We sought to determine parameters of the acute phase response, a feature of innate immunity activated by infectious noxae and cancer, deranged by Covid-19 and establish oncological indices’ prognostic potential for patients with concomitant cancer and Covid-19. Between 27/02 and 23/06/2020, OnCovid retrospectively accrued 1,318 consecutive referrals of patients with cancer and Covid-19 aged 18 from the U.K., Spain, Italy, Belgium, and Germany. Patients with myeloma, leukemia, or insufficient data were excluded. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and prognostic index (PI) were evaluated for their prognostic potential, with the NLR, PLR, and PNI risk stratifications dichotomized around median values and the pre-established risk categorizations from literature utilized for the mGPS and PI. 1,071 eligible patients were randomly assorted into a training set (TS, n=529) and validation set (VS, n=542) matched for age (67.9±13.3 TS, 68.5±13.5 VS), presence of 1 comorbidity (52.1% TS, 49.8% VS), development of 1 Covid-19 complication (27% TS, 25.9% VS), and active malignancy at Covid-19 diagnosis (66.7% TS, 61.6% VS). Among all 1,071 patients, deceased patients tended to categorize into poor risk groups for the NLR, PNI, mGPS, and PI (P6 (44.6% vs 28%, P6 30 days 95%CI 1-63, PNI Citation Format: Gino M.

IMPORTANCE Whether the severity and mortality of COVID-19 in patients with cancer have improved in terms of disease management and capacity is yet to be defined. OBJECTIVE To test whether severity and mortality from COVID-19 among patients with cancer have improved during the course of the pandemic. DESIGN, SETTING, AND PARTICIPANTS OnCovid is a European registry that collects data on consecutive patients with solid or hematologic cancer and COVID-19. This multicenter case series study included real-world data from 35 institutions across 6 countries (UK, Italy, Spain, France, Belgium, and Germany). This update included patients diagnosed between February 27, 2020, and February, 14, 2021. Inclusion criteria were confirmed diagnosis of SARS-CoV-2 infection and a history of solid or hematologic cancer. EXPOSURES SARS-CoV-2 infection. MAIN OUTCOMES AND MEASURES Deaths were differentiated at 14 days and 3 months as the 2 landmark end points. Patient characteristics and outcomes were compared by stratifying patients across 5 phases (February to March 2020, April to June 2020, July to September 2020, October to December 2020, and January to February 2021) and across 2 major outbreaks (February to June 2020 and July 2020 to February 2021). RESULTS At data cutoff, 2795 consecutive patients were included, with 2634 patients eligible for analysis (median [IQR] age, 68 [18-77] years ; 52.8% men). Eligible patients demonstrated significant time-dependent improvement in 14-day case-fatality rate (CFR) with estimates of 29.8% (95% CI, 0.26-0.33) for February to March 2020; 20.3% (95% CI, 0.17-0.23) for April to June 2020;12.5% (95% Cl, 0.06-22.90) for July to September 2020; 17.2% (95% CI, 0.15-0.21) for October to December 2020; and 14.5% (95% CI, 0.09-0.21) for January to February 2021(all P < .001) across the predefined phases. Compared with the second major outbreak, patients diagnosed in the first outbreak were more likely to be 65 years or older (974 of 1626 [60.3%] vs 564 of 1008 [56.1%]; P = .03), have at least 2 comorbidities (793 of 1626 [48.8%) vs 427 of 1008 [42.4%); P = .001), and have advanced tumors (708 of 1626 [46.4%) vs 536 of 1008 [56.1%]: P < .001). Complications of COVID-19 were more likely to be seen (738 of 1626 [45.4%) vs 342 of 1008 [33.9%]; P < .001) and require hospitalization (969 of 1626 [59.8%) vs 418 of 1008 [42.1%); P < .001) and anti-COVID-19 therapy (1004 of 1626 [61.7%) vs 501of 1008 [49.7%); P < .001) during the first major outbreak. The 14-day CFRs for the first and second major outbreaks were 25.6% (95% CI, 0.23-0.28) vs 16.2% (95% CI, 0.13-0.19; P < .001), respectively. After adjusting for country, sex, age, comorbidities, tumor stage and status, anti-COVID-19 and anticancer therapy, and COVID-19 complications, patients diagnosed in the first outbreak had an increased risk of death at 14 days (hazard ratio [HR], 1.85; 95% CI, 1.47-2.32) and 3 months (HR, 1.28; 95% CI, 1.08-1.51) compared with those diagnosed in the second outbreak. CONCLUSIONS AND RELEVANCE The findings of this registry-based study suggest that mortality in patients with cancer diagnosed with COVID-19 has improved in Europe; this improvement may be associated with earlier diagnosis, improved management, and dynamic changes in community transmission over time.

Background: The medium-term and long-term impact of COVID-19 in patients with cancer is not yet known. In this study, we aimed to describe the prevalence of COVID-19 sequelae and their impact on the survival of patients with cancer. We also aimed to describe patterns of resumption and modifications of systemic anti-cancer therapy following recovery from SARS-CoV-2 infection. Methods: OnCovid is an active European registry study enrolling consecutive patients aged 18 years or older with a history of solid or haematological malignancy and who had a diagnosis of RT-PCR confirmed SARS-CoV-2 infection. For this retrospective study, patients were enrolled from 35 institutions across Belgium, France, Germany, Italy, Spain, and the UK. Patients who were diagnosed with SARS-CoV-2 infection between Feb 27, 2020, and Feb 14, 2021, and entered into the registry at the point of data lock (March 1, 2021), were eligible for analysis. The present analysis was focused on COVID-19 survivors who underwent clinical reassessment at each participating institution. We documented prevalence of COVID-19 sequelae and described factors associated with their development and their association with post-COVID-19 survival, which was defined as the interval from post-COVID-19 reassessment to the patients’ death or last follow-up. We also evaluated resumption of systemic anti-cancer therapy in patients treated within 4 weeks of COVID-19 diagnosis. The OnCovid study is registered in ClinicalTrials.gov, NCT04393974. Findings: 2795 patients diagnosed with SARS-CoV-2 infection between Feb 27, 2020, and Feb 14, 2021, were entered into the study by the time of the data lock on March 1, 2021. After the exclusion of ineligible patients, the final study population consisted of 2634 patients. 1557 COVID-19 survivors underwent a formal clinical reassessment after a median of 22·1 months (IQR 8·4–57·8) from cancer diagnosis and 44 days (28–329) from COVID-19 diagnosis. 234 (15·0%) patients reported COVID-19 sequelae, including respiratory symptoms (116 [49·6%]) and residual fatigue (96 [41·0%]). Sequelae were more common in men (vs women; p=0·041), patients aged 65 years or older (vs other age groups; p=0·048), patients with two or more comorbidities (vs one or none; p=0·0006), and patients with a history of smoking (vs no smoking history; p=0·0004). Sequelae were associated with hospitalisation for COVID-19 (p

COVID-19; Cancer; End-of life care (EOLC) COVID-19; Cáncer; Cuidados al final de la vida COVID-19; Càncer; Cures al final de la vida Background: Specialist palliative care team (SPCT) involvement has been shown to improve symptom control and end-of-life care for patients with cancer, but little is known as to how these have been impacted by the COVID-19 pandemic. Here, we report SPCT involvement during the first wave of the pandemic and compare outcomes for patients with cancer who received and did not receive SPCT input from multiple European cancer centres. Methods: From the OnCovid repository (N = 1318), we analysed cancer patients aged ⩾18 diagnosed with COVID-19 between 26 February and 22 June 2020 who had complete specialist palliative care team data (SPCT+ referred; SPCT− not referred). Results: Of 555 eligible patients, 317 were male (57.1%), with a median age of 70 years (IQR 20). At COVID-19 diagnosis, 44.7% were on anti-cancer therapy and 53.3% had ⩾1 co-morbidity. Two hundred and six patients received SPCT input for symptom control (80.1%), psychological support (54.4%) and/or advance care planning (51%). SPCT+ patients had more ‘Do not attempt cardio-pulmonary resuscitation’ orders completed prior to (12.6% versus 3.7%) and during admission (50% versus 22.1%, p

The proportion of cancer patients candidate to receive immune checkpoint inhibitors (ICI) as part of the therapeutic approach is increasing in all settings, from the early to the advanced stage of disease. The management of ICI in special populations of patients with viral hepatitis or autoimmune disease still lacks strong evidence-based recommendations. Patients having one of these two clinical conditions are generally excluded from clinical trials testing immunotherapic compounds. We present the experience of a patient with heavily pretreated advanced non-small-cell lung cancer affected by both chronic active hepatitis C and systemic lupus erythematosus, treated with nivolumab. We give a report of long-term efficacy and safety data, and we provide an insight on this important topic.

BackgroundAge is considered as one of the most important risk-factor for many types of solid and hematological cancers, as their incidence increases with age in parallel to the ever-growing elderly population. Moreover, cancer incidence is constantly increasing as a consequence of the increase in life expectancy that favors the process of cellular senescence. Geriatric assessment has been increasingly recognized as predictive and prognostic instrument to detect frailty in older adults with cancer. In particular, the G8 score is a simple and reproducible instrument to identify elderly patients who should undergo full geriatric evaluation. Due to their frailty, elderly patients may be often under-treated and a therapeutic choice based also on a comprehensive geriatric assessment (CGA) is recommended. With these premises, we aim to test the impact of the CGA based interventions on the quality of life (QoL) of frail elderly onco-hematological patients, identified by the G8 screening, candidate for innovative target directed drugs or treatments including the combination of radiotherapy and chemotherapy (RT + CT).MethodsPatients aged > 65 years, candidate to target directed agents or to RT + CT treatments are screened for frailty by the G8 test; those patients classified as frail (G8 ≤ 14) are randomized to receive a CGA at baseline or to conventional care. The primary endpoint is QoL, assessed by EORTC QLQ-C30C. As collateral biological study, the potential prognostic/predictive role of T-cell senescence and myeloid derived suppressor cells (MDSC) are evaluated on plasma samples.DiscussionThis trial will contribute to define the impact of CGA on the management of frail elderly onco-hematologic patients candidate to innovative biological drugs or to integrated schedules with the association of RT + CT. Furthermore, the use of plasma samples to assess the potential prognostic value of imbalance of immune-competent cells is expected to contribute to the individualized care of elderly patients, resulting into a fine tuning of the therapeutic strategies.Trial registrationClinicalTrials.gov ID:NCT04478916. registered July 21, 2020 – retrospectively registered.

Background: Breast cancer (BC) is the most common neoplasm in women. Many clinical and preclinical studies investigated the possible relationship between host metabolism and BC. Significant differences among BC subtypes have been reported for glucose metabolism. Insulin can promote tumorigenesis through a direct effect on epithelial tissues or indirectly by affecting the levels of other modulators, such as the insulin-like growth factor (IGF) family of receptors, sex hormones, and adipokines. The potential anti-cancer activity of metformin is based on two principal effects: first, its capacity for lowering circulating insulin levels with indirect endocrine effects that may impact on tumor cell proliferation; second, its direct influence on many pro-cancer signaling pathways that are key drivers of BC aggressiveness. Methods: In the present review, the interaction between BC, host metabolism, and patients’ prognosis has been reviewed across available literature evidence. Conclusions: Obesity, metabolic syndrome, and insulin resistance are all involved in BC growth and could have a relevant impact on prognosis. All these factors act through a pro-inflammatory state, mediated by cytokines originated in fat tissue, and seem to be related to a higher risk of BC development and worse prognosis.

Small cell lung cancer (SCLC) is an aggressive tumor with a severe prognosis. At the time of diagnosis, most patients present with extensive-stage (ES) disease. For decades, platinum-based chemotherapy has been the only pillar of SCLC treatment, but now, the clinical management of this disease is rapidly evolving thanks to the introduction of immune checkpoint inhibitors (ICIs).In this review, we describe the most recent advances in the treatment of SCLC and discuss the emerging challenges associated with ICI treatments. Meaningful data were collected from the currently available literature on PubMed and in international oncology meetings.Recently, meaningful improvements in outcomes of SCLC patients have been achieved with anti-PD-L1 atezolizumab or durvalumab combined with chemotherapy in first line. Results of studies evaluating the role of ICIs in limited-stage (LS) SCLC patients are awaited. Further efforts are required to better understand the role of immunotherapy in the treatment of SCLC and to identify patients most likely to benefit from this treatment strategy.

Background: Despite high contagiousness and rapid spread, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to heterogeneous outcomes across affected nations. Within Europe (EU), the United Kingdom (UK) is the most severely affected country, with a death toll in excess of 100,000 as of January 2021. We aimed to compare the national impact of coronavirus disease 2019 (COVID-19) on the risk of death in UK patients with cancer versus those in continental EU. Methods: We performed a retrospective analysis of the OnCovid study database, a European registry of patients with cancer consecutively diagnosed with COVID-19 in 27 centres from 27th February to 10th September 2020. We analysed case fatality rates and risk of death at 30 days and 6 months stratified by region of origin (UK versus EU). We compared patient characteristics at baseline including oncological and COVID-19-specific therapy across UKand EU cohorts and evaluated the association of these factors with the risk of adverse out-comes in multivariable Cox regression models Findings: Compared with EU (n = 924), UK patients (n = 468) were characterised by higher case fatality rates (40.38% versus 26.5%, p < 0.0001) and higher risk of death at 30 days (haz-ard ratio [HR], 1.64 [95% confidence interval {CI}, 1.36-1.99]) and 6 months after COVID-19 diagnosis (47.64% versus 33.33%; p < 0.0001; HR, 1.59 [95% CI, 1.33-1.88]). UK patients were more often men, were of older age and have more comorbidities than EU counterparts (p < 0.01). Receipt of anticancer therapy was lower in UK than in EU patients (p < 0.001). Despite equal proportions of complicated COVID-19, rates of intensive care admission and use of mechanical ventilation, UK patients with cancer were less likely to receive anti-COVID-19 therapies including corticosteroids, antivirals and inter leukin-6 antagonists (p < 0.0001). Multivariable analyses adjusted for imbalanced prognostic factors confirmed the UK cohort to be characterised by worse risk of death at 30 days and 6 months, indepen-dent of the patient's age, gender, tumour stage and status; number of comorbidities; COVID-19 severity and receipt of anticancer and anti-COVID-19 therapy. Rates of permanent cessa-tion of anticancer therapy after COVID-19 were similar in the UK and EU cohorts. Interpretation: UK patients with cancer have been more severely impacted by the unfolding of the COVID-19 pandemic despite societal risk mitigation factors and rapid deferral of anti-cancer therapy. The increased frailty of UK patients with cancer highlights high-risk groups that should be prioritised for anti-SARS-CoV-2 vaccination. Continued evaluation of long-term outcomes is warranted.

Simple Summary Identifying reliable prognostic biomarkers of progression in the early phases of treatment is crucial in patients undergoing immune checkpoints inhibitors (ICI) administration for advanced non-small cell lung cancer (NSCLC). With this aim, in this study we combined the prognostic power of the degree of systemic inflammation (depicted by peripheral inflammation indexes), the quantification of the metabolically active tumor burden (estimated using 18F-fluorodeoxyglucose positron emission tomography/computed tomography) as well as their combination in NSCLC patients receiving immune checkpoints inhibitors. This combined approach could be used to improve the risk stratification and the subsequent clinical management in NSCLC patients treated with immune checkpoints inhibitors. Abstract An emerging clinical need is represented by identifying reliable biomarkers able to discriminate between responders and non-responders among patients showing imaging progression during the administration of immune checkpoints inhibitors for advanced non-small cell lung cancer (NSCLC). In the present study, we analyzed the prognostic power of peripheral-blood systemic inflammation indexes and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in this clinical setting. In 45 patients showing radiological progression (defined as RECIST 1.1 progressive disease) during Nivolumab administration, the following lab and imaging parameters were collected: neutrophil-to-lymphocyte ratio (NLR), derived-NLR (dNLR), lymphocyte-to-monocyte ratio (LMR), platelets-to-lymphocyte ratio (PLR), systemic inflammation index (SII), maximum standardized uptake value, metabolic tumor volume (MTV), and total lesion glycolysis (TLG). MTV and SII independently predicted OS. Their combination in the immune metabolic prognostic index (IMPI) allowed the identification of patients who might benefit from immunotherapy continuation, despite radiological progression. The combination of FDG PET/CT volumetric data with SII also approximates the immune-metabolic response with respect to baseline, providing additional independent prognostic insights. In conclusion, the degree of systemic inflammation, the quantification of the metabolically active tumor burden, and their combination might disclose the radiological progression in NSCLC patients receiving Nivolumab.

We describe the outcomes in cancer patients during the initial outbreak of the COVID-19 in Europe from the retrospective, multi-center observational OnCovid study. We identified 204 cancer patients from eight centers in the United Kingdom, Italy, and Spain aged &gt, 18 (mean = 69) and diagnosed with COVID-19 between February 26th and April 1st, 2020. A total of 127 (62%) were male, 184 (91%) had a diagnosis of solid malignancy, and 103 (51%) had non-metastatic disease. A total of 161 (79%) had &gt, 1 co-morbidity. A total of 141 (69%) patients had &gt, 1 COVID-19 complication. A total of 36 (19%) were escalated to high-dependency or intensive care. A total of 59 (29%) died, 53 (26%) were discharged, and 92 (45%) were in-hospital survivors. Mortality was higher in patients aged &gt, 65 (36% versus 16%), in those with &gt, 2 co-morbidities (40% versus 18%) and developing &gt, 1 complication from COVID-19 (38% versus 4%, p = 0.004). Multi-variable analyses confirmed age &gt, 65 and &gt, 2 co-morbidities to predict for patient mortality independent of tumor stage, active malignancy, or anticancer therapy. During the early outbreak of SARS-CoV-2 infection in Europe co-morbid burden and advancing age predicted for adverse disease course in cancer patients. The ongoing OnCovid study will allow us to compare risks and outcomes in cancer patients between the initial and later stages of the COVID-19 pandemic.

Higher risk of death from COVID-19 among patients with cancer was correlated with male sex, greater age, presence of multiple comorbidities, advanced-stage disease, and active disease; there was no association between risk and anticancer treatment., The SARS-CoV-2 pandemic significantly affected oncology practice across the globe. There is uncertainty as to the contribution of patients' demographics and oncologic features to severity and mortality from COVID-19 and little guidance as to the role of anticancer and anti–COVID-19 therapy in this population. In a multicenter study of 890 patients with cancer with confirmed COVID-19, we demonstrated a worsening gradient of mortality from breast cancer to hematologic malignancies and showed that male gender, older age, and number of comorbidities identify a subset of patients with significantly worse mortality rates from COVID-19. Provision of chemotherapy, targeted therapy, or immunotherapy did not worsen mortality. Exposure to antimalarials was associated with improved mortality rates independent of baseline prognostic factors. This study highlights the clinical utility of demographic factors for individualized risk stratification of patients and supports further research into emerging anti–COVID-19 therapeutics in SARS-CoV-2–infected patients with cancer. Significance: In this observational study of 890 patients with cancer diagnosed with SARS-CoV-2, mortality was 33.6% and predicted by male gender, age ≥65, and comorbidity burden. Delivery of cancer therapy was not detrimental to severity or mortality from COVID-19. These patients should be the focus of shielding efforts during the SARS-CoV-2 pandemic.

Introduction: The discovery of new actionable oncogenic drivers has led to the development of effective antineoplastic targeted agents in advanced non-small cell lung cancer (NSCLC). While the role of inhibitors of the epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and ROS proto-oncogene 1 (ROS1) is widely acknowledged, other oncogenic drivers can be exploited as therapeutic targets.Areas covered: Our aim is to explore the therapeutic role of actionable oncogenic drivers, including well-established targets, such as EGFR, ALK, and ROS1, as well as less frequent drivers for which specific agents are at different stages of clinical development, such as MET, RET, BRAF, and NTRK.Expert opinion: Targeted agents have revolutionized the management of advanced NSCLC; in particular, novel agents and combinations targeting EGFR, ALK, ROS1, BRAF, and NTRK have become available and others are on their way. The molecularly driven approach to advanced NSCLC requires adequate tumor samples, as well as increasingly complex technologies designed to assess multiple targets on limited available tissue in an acceptable time-span. Furthermore, the role of other novel antineoplastic approaches, such as immunotherapy with immune checkpoint inhibitors, needs to be elucidated in the case of patients with oncogenic-driven NSCLC.

Introduction Breast cancer survivors are at increased risk of developing unrelated primary cancers, particularly lung cancer. Evidence indicates that sex hormones as well as a deregulation of DNA-repair pathways may contribute to lung cancer onset. We investigated whether the hormone status and expression of markers involved in DNA repair (BRCA1/2, ERCC1, and P53R2), synthesis (TS and RRM1), and cell division (TUBB3) might be linked to lung cancer risk. Patients and Methods Thirty-seven breast cancer survivors with unrelated lung cancer and 84 control subjects comprising women with breast cancer (42/84) or lung cancer (42/84) were enrolled. Immunohistochemistry on tumor tissue was performed. Geometric mean ratio was used to assess the association of marker levels with patient groups. Results Estrogen receptor was expressed in approximately 90% of the breast cancer group but was negative in the majority of the lung cancer group, a result similar to the lung cancer control group. Likewise, ER isoform β was weakly expressed in the lung cancer group. Protein analysis of breast cancer versus control had a significantly lower expression of BRCA1, P53R2, and TUBB3. Likewise, a BRCA1 reduction was observed in the lung cancer group concomitant with a BRCA2 increase. Furthermore, BRCA2 and TUBB3 increased in ipsilateral lung cancer in women who had previously received radiotherapy for breast cancer. Conclusion The decrease of DNA-repair proteins in breast cancer could make these women more susceptible to therapy-related cancer. The increase of BRCA2 and TUBB3 in lung cancer from patients who previously received radiotherapy for breast cancer might reflect a tissue response to exposure to ionizing radiation.

Because of the peculiar mechanism of action of immune checkpoint inhibitors (ICIs), evaluation of the radiologic response to them in solid tumors presents many challenges. We aimed to compare evaluation of the first response to nivolumab by means of CT-based criteria with respect to 18F-FDG PET response criteria in non–small cell lung cancer (NSCLC) patients. Methods: Seventy-two patients with advanced NSCLC were recruited in a single-institution ancillary trial within the expanded-access program (NCT02475382) for nivolumab. Patients underwent CT and 18F-FDG PET at baseline and after 4 cycles (the first evaluation). In cases of progressive disease, an additional evaluation was performed after 2 further cycles to confirm progression. We evaluated the treatment response on CT using RECIST 1.1 and the immune-related response criteria (irRC) and on 18F-FDG PET using PERCIST and immunotherapy-modified PERCIST. The concordance between CT- and PET-based criteria and the capability of each method to predict overall survival were evaluated. Results: Forty-eight of 72 patients were evaluable for a first response assessment with both PET- and CT-based criteria. We observed low concordance between CT- and PET-based criteria (κ-value of 0.346 and 0.355 between PERCIST and imPERCIST and RECIST, respectively. κ-value of 0.128 and 0.198 between PERCIST and imPERCIST and irRC, respectively). Regarding overall survival, irRC could more reliably distinguish responders from nonresponders. However, thanks to the prognostic value of partial metabolic response assessed by both PERCIST and immunotherapy-modified PERCIST, PET-based response maintained prognostic significance in patients classified as having progressive disease on the basis of irRC. Conclusion: Even though the present study did not support the routine use of 18F-FDG PET in the general population of NSCLC patients treated with ICIs, the findings suggest that metabolic response assessment has added prognostic value, potentially improving therapeutic decision making.

Immune checkpoint blockade represents a major breakthrough in advanced non-small cell lung cancer (NSCLC) therapy. However, success is limited to a subset of patients and there is a critical need to identify robust biomarkers associated with clinical response. In this study, we assessed whether pre-existing immunological characteristics, as well as immune parameters measured during treatment, might provide such clinical guidance. We studied blood samples collected at baseline and during treatment in a cohort of advanced NSCLC patients (n = 74) treated with nivolumab. Several lymphocyte subsets and biomarkers were then correlated with overall survival (OS) as well as clinical response, assessed using RECIST criteria. We found that patients characterized by longer OS had higher levels of CD3+, CD4+, and CD8+ T cells but lower levels of NK cells at baseline. Moreover, that they displayed a statistically significant lower expression of PD-1 on both CD3+ and CD8+ T cells (p = 0.013 and p = 0.033, respectively). The pre-treatment level of exhausted T cells (CD8+PD1+Eomes+) was significantly lower in patients with controlled disease (CD), defined as partial response (PR), and stable disease (SD), compared to those with progressive disease (PD) (p = 0.046). In CD patients, the frequency of exhausted CD8+ T cells further decreased during treatment cycles (p =

Non-small cell lung cancer (NSCLC) remains one of the big cancer killers, despite the introduction of a number of approved therapeutics in recent times. Pemetrexed is a multi-target folate inhibitor, which is currently available to patients affected by advanced non-squamous NSCLC in combination with a platinum derivate in first-line therapy and as a single agent in second-line therapy. Areas covered: This review covers presents the use pemetrexed in the management of NSCLC by exploring the data available from clinical trials and meta-analyses. Data from a phase III trial confirmed its role in the first-line setting in combination with immune checkpoint inhibitors (ICIs). Furthermore, data suggested a role for pemetrexed in local and advanced NSCLC. Expert opinion: To date, in spite of the introduction of novel anti-neoplastic agents, pemetrexed still represents a cornerstone in the management of non-squamous NSCLC. Furthermore, recently published data support its role in innovative combinations including together with chemotherapy and immunotherapy.

Since the role of resistin was evaluated only in patients with non-small cell lung cancer (NSCLC) not treated with immunotherapy, we aimed to evaluate levels of resistin during immunotherapy (nivolumab) and its prognostic role with regard to OS. From a cohort of 78 patients with advanced NSCLC enrolled in a prospective study at Ospedale Policlinico San Martino in Genoa (Italy), 43 patients have been considered for this sub-analysis because of the availability of samples. Before and during nivolumab administration, clinical information and blood samples were collected and resistin, matrix metalloproteinase (MMP)-8, MMP-9, and myeloperoxidase were evaluated by enzyme-linked immunosorbent assay (ELISA). Median age was 71 with a prevalence of males and former smokers. Median resistin levels presented a peak at cycle 2 and then dropped down until the last cycle. Resistin correlated with all neutrophil degranulation products at cycle 1 (except for MMP-9) and at cycle 2 as well as with white blood cells and neutrophils. By a ROC curve analysis, a resistin value at cycle 2 of 19 ng/mL was tested as the best cut-off point for OS. Kaplan–Meier analysis demonstrated that patients above the resistin cut-off experienced a reduced OS (median OS 242.5 vs. 470 days, p = 0.0073), as confirmed by Cox proportional hazards regression analysis. Resistin levels > 19 ng/mL at the time of the second cycle of nivolumab treatment independently predict a reduced OS in patients with advanced NSCLC.

Objectives VeriStrat® is a blood-based test that utilizes matrix-assisted laser desorption/ionization time-of-flight (MALDI ToF) mass spectrometry to assign a binary classification of VeriStrat Good or VeriStrat Poor that is associated with treatment outcomes in cancer patients. A number of other studies have shown an association between VeriStrat status and clinical outcomes in second and subsequent lines of therapy. The prognostic properties of VeriStrat were demonstrated in the placebo arms of two randomized studies in non-small cell lung cancer (NSCLC): TOPICAL and BR.21; the predictive properties of the test were shown in a prospective randomized phase III study PROSE in the second line treatment of NSCLC with erlotinib versus chemotherapy. Motivated by these observations, we sought to extend the clinical utility of VeriStrat to standard first line chemotherapy and evaluated the performance of the test in a number of clinical studies of patients treated with platinum-based regimens. Materials and methods We examine the performance of VeriStrat in three independent clinical trials where the test classification was acquired for prospectively collected baseline samples from 481 patients treated with platinum-based chemotherapy in first line. Results Across these trials, 66–70% of patients were classified as VeriStrat Good; patients classified as VeriStrat Good had significantly longer progression-free survival and overall survival than VeriStrat Poor patients, with hazard ratios ranging from 0.36 to 0.72 and 0.26 to 0.51, respectively. These results demonstrated that VeriStrat is a strong prognostic test in NSCLC patients treated with platinum-based regimens in the first line. Conclusion VeriStrat provides valuable clinical information that may be used to support patient-physician conversations regarding prognosis and treatment options, and to identify a subset of patients who might benefit from other treatment strategies, possibly in the framework of clinical trials.

Background: The long-term impact of COVID-19 in cancer patients (pts) is undefined. Methods: Among 2795 consecutive pts with COVID-19 and cancer registered to OnCovid between 01/2020 and 02/2021, we examined clinical outcomes of pts reassessed post COVID-19 recovery. Results: Among 1557 COVID-19 survivors, 234 (15%) reported sequelae including respiratory symptoms (49.6%), fatigue (41%) and cognitive/psychological dysfunction (4.3%). Persisting COVID-19 sequelae were more likely found in males (p=0.0407) aged ≥65 years (p=0.0489) with ≥2 comorbidities (p=0.0006) and positive smoking history (p=0.0004). Sequelae were associated with history of prior hospitalisation (p

We aimed to evaluate the relationships between circulating tumor cells (CTCs) or plasma cell-free DNA (cfDNA) on one side and a comprehensive range of 18F-FDG PET/CT-derived parameters on the other side in chemotherapy-naive patients with advanced non-small cell lung cancer (NSCLC). Methods: From a group of 79 patients included in a trial evaluating the role of pretreatment circulating tumor markers as predictors of prognosis in chemotherapy-naive patients with advanced NSCLC, we recruited all those who underwent 18F-FDG PET/CT for clinical reasons at our institution before inclusion in the trial (and thus just before chemotherapy). For each patient, a peripheral blood sample was collected at baseline for the evaluation of CTCs and cfDNA. CTCs were isolated by size using a filtration-based device and then morphologically identified and enumerated; cfDNA was isolated from plasma and quantified by a quantitative polymerase chain reaction using human telomerase reverse transcriptase. The following 18F-FDG PET/CT-derived parameters were computed: maximum diameter of the primary lesion (T), of the largest lymph node (N), and of the largest metastatic lesion (M); SUVmax; SUVmean; size-incorporated SUVmax; metabolic tumor volume; and total lesion glycolysis. All parameters were independently measured for T, N, and M. The associations among CTCs, cfDNA, and 18F-FDG PET/CT-derived parameters were evaluated by multivariate-analysis. Patients were divided into 2 groups according to the presence of either limited metastatic involvement (M1a or M1b due to extrathoracic lymph nodes only) or disseminated metastatic disease. The presence or absence of metabolically active bone lesions was also recorded for each patient, and patient subgroups were compared. Results: Thirty-seven patients recruited in the trial matched our PET-based criteria (24 men; age, 64.5 ± 8.1 y). SUVmax for the largest metastatic lesion was the only variable independently associated with baseline cfDNA levels (P = 0.016). Higher levels of cfDNA were detected in the subgroup of patients with metabolically active bone lesions (P = 0.02), but no difference was highlighted when patients with more limited metastatic disease were compared with patients with disseminated metastatic disease. Conclusion: The correlation of cfDNA levels with tumor metabolism, but not with metabolic tumor volume at regional or distant levels, suggests that cfDNA may better reflect tumor biologic behavior or aggressiveness rather than tumor burden in metastatic NSCLC.

Introduction: Fibroblast growth factor receptor (FGFR) due to its central role in regulating cell survival, is a promising target for cancer therapeutics. Dysregulation of the FGFR pathway has been observed in several malignancies, including non-small cell lung cancer (NSCLC) particularly in patients with squamous histology.Areas covered: The aim of this article is to review the most relevant findings of clinical trials investigating drugs targeting FGFR pathway: such as FGFR tyrosine kinase inhibitors (TKIs), FGFR monoclonal antibodies and FGF ligand traps in NSCLC patients.Expert opinion: At present, clinical activity of drugs targeting FGFR in NSCLC is disappointing. Further studies are needed in order to better identify patients who might benefit from these drugs and to clarify the mechanisms of resistance to these compounds.

Reliable predictors of benefit from immune checkpoint inhibitors in non-small-cell lung cancer (NSCLC) are still limited. We aimed to evaluate the association between the expression of selected molecules involved in immune response and clinical outcomes in NSCLC patients receiving nivolumab. In our study, the outcomes of 46 NSCLC patients treated with nivolumab in second or subsequent lines (Nivolumab Cohort) were compared with the expression of PD-L1, PD-L2, PD-1, B7-H3, and B7-H4 assessed by immunohistochemistry (IHC). Samples from 17 patients (37.0%) in the Nivolumab Cohort were positive for B7-H4 expression. At univariate analyses, only B7-H4 expression was associated with significantly decreased progression-free survival (PFS, 1.7 vs. 2.0 months, p = 0.026) and with a disadvantage in terms of overall survival (OS) close to statistical significance (4.4 vs. 9.8 months, p = 0.064). At multivariate analyses, B7-H4 expression was significantly associated with decreased PFS (hazard ratio (HR) = 2.28, p = 0.021) and OS (HR = 2.38, p = 0.022). Subsequently, B7-H4 expression was compared with clinical outcomes of 27 NSCLC patients receiving platinum-based chemotherapy (Chemotherapy Cohort), but no significant association was observed. Our results suggest a negative predictive role of B7-H4 in a population of NSCLC treated with immune checkpoint inhibitors, which deserves further research.

Treatment with nivolumab improves survival and response rate in non-small cell lung cancer (NSCLC). Nevertheless, due to its high financial cost, identifying predictors of response to treatment has become an urgent need. Here, we focused on serum osteopontin (OPN), a pleiotropic protein overexpressed in lung cancer and involved in the immune response. A cohort of NSCLC patients (n = 72) treated with nivolumab was enrolled. Blood samples were collected at the time of first five nivolumab administrations. OPN and high-sensitivity C-reactive protein (hs-CRP) were assayed at each time point. The primary endpoint was to assess the predictive value of baseline serum levels of OPN towards overall survival (OS). Secondary endpoints included the potential association between OPN, hs-CRP and response to nivolumab. OPN and hs-CRP correlate with each other, with neutrophil count and biochemical markers of metastatic disease. At baseline, serum OPN increased with increasing Eastern Cooperative Oncology Group scale of Performance Status (ECOG PS). When Eastern Cooperative Oncology Group scale of Performance Status) (RECIST) criteria were considered, high baseline OPN levels were associated with a worse response to nivolumab. Cox hazard regression further confirmed baseline serum OPN as a predictor of mortality with the best predictive accuracy for serum levels above 37.7 ng/mL. Patients above the cut-off value had a higher mortality rate as compared to low serum OPN levels during follow up. Serum OPN may have a predictive role in NSCLC patients treated with nivolumab. Although larger confirmatory studies are needed, measuring serum OPN levels at baseline can be a clinically useful tool in a near future.

Monoclonal antibodies targeting PD-1 are used for treating NSCLC. To date, proprotein convertase subtilisin/kexin type 9 (PCSK9) has been poorly investigated in the oncologic field. Here, we aimed at evaluating whether serum PCSK9 might represent a predictive factor for OS in older patients with advanced NSCLC under nivolumab treatment. Among 78 patients with advanced, pre-treated NSCLC previously enrolled in a prospective study at Ospedale Policlinico San Martino in Genoa (Italy), 44 patients have been included in this sub-analysis due to the availability of serum samples for the measurement of PCSK9. Before each nivolumab administration, clinical information and blood samples were collected. Median age was 71, with a prevalence of the male sex. The most represented histological type of lung cancer was adenocarcinoma. The majority of patients were former smokers (72.1%). Median PCSK9 levels were 123.59 (86.32–169.89) ng/mL and 117.17 (80.46–147.79) ng/mL at cycle 1 and 2, respectively. Based on a receiver operating characteristic curve analysis, a PCSK9 value at cycle 2 of 95 ng/mL was found as the best cutoff point for OS. Kaplan–Meier analysis demonstrated that patients below the PCSK9 cutoff (

Background CEA, CYFRA21-1 and NSE are tumor markers used for monitoring the response to chemotherapy in advanced adenocarcinoma, squamous cell carcinoma and small-cell lung cancer, respectively. Their role in cancer immunotherapy needs to be elucidated. Methods Patients with advanced non-small cell lung cancer (NSCLC) were treated with nivolumab 3 mg/kg every 2 weeks within the Italian Nivolumab Expanded Access Program. Blood samples were collected at baseline, at each cycle up to cycle 5 and then every two cycles until patient’s withdrawn from the study. All patients underwent a CT-scan after every 4 cycles of treatment and responses were classified according to RECIST 1.1. The biomarkers serum levels were measured with a chemiluminescent microparticle immunoassay for CEA and with an immuno radiometric assay for CYFRA21-1 and NSE. The markers values at baseline and after 4 cycles were used to analyze the relationship between their variation over baseline and the tumor response, evaluated as disease control rate (DCR: CR + PR + SD), and survival (PFS and OS). Results A total of 70 patients were evaluable for the analysis. Overall, a disease control was obtained in 24 patients (35.8%, 4 PR + 20 SD). After 4 cycles of nivolumab a CEA or CYFRA21-1 reduction ≥ 20% over the baseline was significantly associated with DCR (CEA, p = 0.021; CYFRA21-1, p

12038 Background: Elderly cancer patients may have important benefits from innovative treatments. However, they are often barred from clinical trials because of highly selective eligibility criteria, or due to biased and subjective physician standpoints including reluctance to invite elderly patients and fear of excessive toxicity. Indeed, geriatric assessment has been increasingly recognized as predictive and prognostic instrument to detect frailty in older adults with cancer. In this perspective, the G8 score is a simple and reproducible instrument to identify elderly patients who should undergo full geriatric evaluation. The aim of our study was to evaluate the impact of frailty assessment by the G8 screening tool on the outcome of onco-hematological patients. Methods: Between January 2017 and December 2020 the G8 screening tool was administered to patients, aged >65 years, referred to our center for solid and hematological malignancies. G8 score was assessed at the time of first access. The primary endpoint was overall survival. Multivariate analysis was performed according to G8 score, age, tumor type, stage and treatment. Results: In the observation period, 430 patients were screened for frailty by G8; median age was 77 years (65-92); of these, 331 (77%) had a G8 score 14 (OR 3.26, CI 95 1.5-7.2, p = 0.003). Conversely, this increased risk was not observed in hematological malignancies (OR 1.4, CI 95 0.4-4.6, p = 0.57). By multivariate analysis, G8 score was associated with a worse prognosis only in patients with solid tumors. Conclusions: Our analysis suggest that elderly frail patients with solid tumors have a significantly increased risk of death as compared to elderly fit patients. Conversely, no impact of frailty, as assessed by a G8 score < 14, was evident in elderly patients with hematological malignancies.

Vinflunine belongs to the class of vinca alkaloids and acts by disrupting the microtubule dynamics during cell cycle; this agent is currently available for previously treated advanced transitional cell carcinoma in Europe. The aim of this invited review is to evaluate the potential role of vinflunine for the treatment of non-small cell lung cancer (NSCLC). Areas covered: The potential role of vinflunine in NSCLC is discussed on the basis of the available data, including full papers and meeting abstracts. Relevant preclinical studies describing the pharmacological properties of vinflunine are also included. The review also summarizes clinical studies, including phase I trials involving NSCLC among other tumors as well as phase II/III trials specifically addressing this malignancy. Additionally, the safety profile and the current regulatory status of vinflunine is discussed. Expert opinion: Vinflunine is active as single agent and as part of platinum-based combinations in NSCLC. It results non-inferior to docetaxel in a randomized phase III trial including previously treated NSCLC patients; additionally, its safety profile is generally considered manageable. Ultimately, further studies are needed to confirm the role of vinflunine in NSCLC, in consideration of the evolving evidence regarding targeted therapies and immune check-point inhibitors.

Background The severity of SARS-CoV-2 infection (COVID-19) is predicted by advancing age and co-morbidities. The relative contribution of cancer in influencing the course of COVID-19 is poorly understood. We designed the OnCOVID study to investigate natural history of COVID-19 disease in cancer patients. Methods This retrospective, multi-center observational study conducted across 8 tertiary centers in Europe recruited cancer patients aged >/= 18 and diagnosed with COVID-19 between February 26th and April 1st, 2020. Descriptive statistics, univariable and multivariable Cox regression models were used to assess patient’s main characteristics and to evaluate the factors associated to COVID-19 related mortality. Results We identified 204 patients from United Kingdom (n=97, 48%), Italy (n=56, 27%) and Spain (n=51, 25%). Most patients were male (n=127, 62%) had a diagnosis of solid malignancy (n=184, 91%) and 103 (51%) had non-metastatic disease. Mean (±SD) patient age was 69±13 years, and 161 (79%) had >/= 1 co-morbidity, most commonly hypertension (n=88, 43%) and diabetes (n=46, 23%). Commonest presenting symptoms were fever (n=136, 67%) and cough (n=119, 58%), beginning 3.8 (±4.5 SD) days before diagnosis. Most patients (n=141, 69%) had >/= 1 complication from COVID-19, including respiratory failure (n=128, 63%) and acute respiratory distress syndrome (n=49, 24%). In total, 36 patients (19%) patients were escalated to high-dependency or intensive care. At time of analysis, 59 patients had died (29%), 53 were discharged from hospital (26%) and 92 (45%) were in-hospital survivors. Mortality was higher in patients aged >/= 65 (36% versus 16%), in those with >/= 2 co-morbidities (40% versus 18%) and developing >/= 1 complication from COVID-19 (38% versus 4%, p=0.004). Multi-variable analyses confirmed age >/= 65 and >/= 2 co-morbidities to predict for patient mortality independent of tumor stage, active malignancy or anti-cancer therapy. Conclusions In the early outbreak of SARS-CoV-2 infection in Europe co-morbid burden and advancing age predicted for adverse disease course in cancer patients. Risk stratification based on these factors should inform personalized oncological decision making during the COVID-19 pandemic. Legal entity responsible for the study Imperial College London.

e15263 Background: The introduction of immune check-point inhibitors (ICIs) in the treatment of a broad range of tumor types has led to a significant and clinically meaningful improvement in overall survival (OS) in advanced disease stages. However, the efficacy of these agents is not consistent across trials and in routine practice. The role of PD-L1 expression as a tumour-agnostic predictive correlate of response to ICIs remains unclear. We performed a pooled analysis of the efficacy of PD-1/PD-L1-targeted ICI regimens as compared to standard of care (SoC) therapy according to PD-L1 expression, based on landmark clinical studies. Methods: We searched literature databases to identify phase III randomized controlled trials that compared anti-PD-1/PD-L1 antibodies alone or in combination with chemotherapy or targeted agents against SoC therapy in the treatment of different tumor types. We reported efficacy data, in terms of OS, according to PD-L1 status. Log hazard ratios (HRs) were pooled across the studies overall and by PD-L1 status by inverse variance weighting. All statistical tests were two-sided. Results: Twenty-four studies including 17687 randomised patients with advanced lung, renal, urothelial, liver, breast, head and neck cancers and melanoma, were eligible for analysis. Efficacy according to PD-L1 immunohistochemical expression, with a 1% cutoff ( < 1% versus > 1%), was reported in 11 studies (7126 patients). Overall, ICI-containing regimes were significantly superior in terms of OS to SoC regimens (pooled HR = 0.64; 95% CI 0.60 to 0.68). When OS data were pooled according to PD-L1 expression, HR was 0.66; 95% CI 0.61 to 0.71 in PD-L1 < 1%, versus 0.62; 95% CI 0.56 to 0.68 in PD-L1 >1% (p = 0.7). Conclusions: The significant improvement in OS favoring the use of ICIs over SoC does not seem to be confined to patients with PD-L1-overexpressing tumours. The difference in efficacy according to PD-L1 status appears to be, at best, marginal.

Lung cancer represents the most common cause of cancer death worldwide. While the prognosis remains poor, immunotherapy is giving a positive impact on survival. Cancer vaccines represent a form of active immunotherapy that historically has given modest results in terms of efficacy. The overexpression of the EGFR by tumor cells was reported in more than half of cases of lung cancer, representing a mechanism of cancerogenesis. CIMAvax-EGF, a therapeutic vaccine for non-small cell lung cancer (NSCLC) developed in Cuba, consists of a human recombinant EGF able to induce antibodies against the autologous EGF, resulting in serum EGF withdrawal and lower EGF-EGFR interaction. Area covered: We critically reviewed the existing literature about CIMAvax-EGF, from the Pilot studies to the efficacy controlled studies. We also overviewed the ongoing trials. Expert opinion: CIMAvax-EGF demonstrated to be safe and immunogenic. In a phase III randomized study CIMAvax-EGF, used as a switch maintenance treatment after platinum-based chemotherapy, did not significantly improve survival. Current data are not sufficient to recommend CIMAvax-EGF as a treatment option for advanced stage NSCLC. Further studies, conducted in a context of worldwide standardized clinical practice, are needed to better define if a subpopulation of patients can benefit from the vaccination.

Background Rare cases of severe myocarditis are reported during treatment with nivolumab. Troponin, a biomarker of cardiac damage, is a key component of the diagnostic workup of many cardiac disorders, including myocarditis. This study investigates the role of troponin to assess cardiac involvement during nivolumab therapy for non-small cell lung cancer (NSCLC). Materials and Methods We evaluated 59 NSCLC patients, analyzing serum samples collected within a translational research study. Troponin above the upper normal limit (0.046 ng/mL) was defined as Tn+, whereas normal but detectable troponin (0.015–0.045) was defined as Tndet. Troponin alterations were interpreted on the grounds of the following elements: peak values and time curve, cardiac comorbidities, signs and symptoms coincident to troponin elevation, ECG, echocardiography, and disease progression. Results No patient had cardiovascular events. Among 362 available blood samples, Tn+ (max 0.317 ng/mL) was found in 13 determinations belonging to 6 patients. Seven other patients had isolated Tndet. In five patients, Tn+ was attributed to cardiac comorbidities, disease progression, or worsening clinical status. One patient without cardiac history and in good clinical condition had a sustained troponin increase—soon after the start of therapy—and after careful evaluation of all relevant elements, it was interpreted as a marker of nivolumab-related subclinical myocarditis. Conclusion Tn+ may occur in NSCLC patients treated with nivolumab, but in most cases it does not indicate nivolumab cardiotoxicity. In some cases, however, a careful interpretation of troponin alteration, especially at the beginning of therapy, enables identification of subclinical myocarditis, thus allowing early cardiac treatment. Implications for Practice Myocarditis is a rare but serious adverse event of immune checkpoint blockade with nivolumab, which needs to be recognized as soon as possible. This article suggests that troponin, a user-friendly biomarker of myocardial cytotoxicity, might be useful for early detection of immune-mediated myocarditis. However, because troponin abnormalities might also be related to a number of conditions capable of causing myocardial oxygen demand-supply mismatch, a careful cardiac assessment should be performed in non-small cell lung cancer patients in order to properly interpret any troponin increase. According to the available evidence, monitoring troponin during the first weeks of treatment can be considered reasonable.

Introduction Squamous-cell carcinoma (SCC) of the lung represents around 20% of non-small cell lung cancers. Although activating mutations of EGFR are rare in this subtype, its overexpression occurs in more than half the cases. Consequently, many epidermal growth factor receptor (EGFR)-targeted agents have been investigated in patients with SCC. Areas covered This review summarizes the potential roles of erlotinib and afatinib in SCC of the lung. The authors explore the rationale of targeting EGFR in SCC and the pharmacological properties of erlotinib and afatinib. Subsequently, they describe the most relevant clinical data involving each agent with regard to their safety profile and antineoplastic activity. Particular focus is given to the LUX-Lung 8 trial, which compared erlotinib and afatinib as a second-line treatment in a population of patients affected by advanced SCC of the lung. Expert opinion Despite being overcome by new therapeutic strategies - in particular immune checkpoint inhibitors - afatinib and erlotinib still represent potential treatment options down the line in lung SCC because they have a more manageable toxicity profile compared to chemotherapy.

Preclinical studies have suggested that combining cytotoxic agents with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) to treat EGFR-mutated tumors may increase their inhibitory effect depending on the order of drug administration. The antitumor efficacy of different treatment sequences using vinorelbine (VNB) and gefitinib (GEF) was investigated both in vitro and in vivo in non-small cell lung cancer (NSCLC) cell lines with the rationale of potentially translating these findings into the clinical setting. The EGFR-wild-type A549 and the EGFR-mutated (exon 21 L858R/exon 20 T790M) H1975 cell lines were treated as follows: GEF followed by VNB, VNB followed by GEF and the two drugs applied individually or concurrently. Results in vitro demonstrated that the sequence of VNB followed by GEF was significantly more active than single-agent treatments. The expression of activated EGFR and its downstream pathway genes indicated that the increased cytotoxic effect of the VNB and GEF treatment sequence was accompanied by inhibition of EGFR, AKT and ERK1/2. Moreover, the increased inhibition of tumor growth after treatment with VNB followed by GEF was also confirmed in CD1-nude mice that were xenotransplanted with H1975 cells (p

Immune check-point inhibitors are now employed as single-agents in current practice for the treatment of advanced non-small cell lung cancer (NSCLC), while combinations of different inhibitors are being evaluated in clinical trials. Although the safety profile of these compounds, with particular reference to drugs targeting programmed death protein 1 (PD-1) and its ligand (PD-L1), is generally considered manageable, peculiar, immune-related toxicities may onset. Areas covered: This review focuses on the immune-related adverse events (irAEs) observed during immune check-point blockade in NSCLC and their management. The authors report the incidence of irAEs based on the currently available data involving NSCLC and provide recommendations on the general approach to irAEs, as well as indications for the most relevant site-specific events. Expert opinion: Since irAEs may involve a wide range of organs and systems and are potentially reversible if promptly treated, early diagnosis should always be achieved; this might be particularly challenging when other potential causes of toxicity are suspected, such as infections or concurrent treatments. Finally, drugs active on the PD-1/PD-L1 axis appear to be generally manageable even when they are administered to patients with relevant comorbidities, provided that adequate clinical monitoring is performed.

Cell-free DNA (cfDNA) and circulating tumor cells (CTCs) are promising prognostic and predictive biomarkers in non-small cell lung cancer (NSCLC). In this study, we examined the prognostic role of cfDNA and CTCs, in separate and joint analyses, in NSCLC patients receiving first line chemotherapy. Seventy-three patients with advanced NSCLC were enrolled in this study. CfDNA and CTC were analyzed at baseline and after two cycles of chemotherapy. Plasma cfDNA quantification was performed by quantitative PCR (qPCR) whereas CTCs were isolated by the ScreenCell Cyto (ScreenCell, Paris, France) device and enumerated according to malignant features. Patients with baseline cfDNA higher than the median value (96.3 hTERT copy number) had a significantly worse overall survival (OS) and double the risk of death (hazard ratio (HR): 2.14; 95% confidence limits (CL) = 1.24–3.68; p-value = 0.006). Conversely, an inverse relationship between CTC median baseline number (6 CTC/3 mL of blood) and OS was observed. In addition, we found that in patients reporting stable disease (SD), the baseline cfDNA and CTCs were able to discriminate patients at high risk of poor survival. cfDNA demonstrated a more reliable biomarker than CTCs in the overall population. In the subgroup of SD patients, both biomarkers identified patients at high risk of poor prognosis who might deserve additional/alternative therapeutic interventions.

Background: VeriStrat is a blood-based proteomic test with predictive and prognostic significance in second-line treatments for non-small cell lung cancer (NSCLC). This trial was designed to investigate the role of VeriStrat in first-line treatment of advanced NSCLC with standard chemotherapy. Here we present the results for 76 non-squamous patients treated with a combination of carboplatin or cisplatin with pemetrexed. Methods: The test-assigned classifications of VeriStrat Good or VeriStrat Poor to samples collected at baseline. The primary end point was progression-free survival (PFS); secondary end points included overall survival (OS) and objective response. Exploratory analyses of end points separately in carboplatin/pemetrexed and cisplatin/pemetrexed subgroups were also conducted. Results: Patients classified as VeriStrat Good had longer PFS and OS than VeriStrat Poor: 6.5 vs 1.6 months and 10.8 vs 3.4 months, respectively; the corresponding hazard ratios (HRs) were 0.36 (P

Originally formulated as an intravenous (i.v.) agent, vinorelbine is also currently available as an oral chemotherapeutic agent. Oral vinorelbine has demonstrated significant activity in different settings for NSCLC, including adjuvant treatment for resected disease, concurrent chemoradiation for locally advanced NSCLC and palliative chemotherapy for recurrent/metastatic NSCLC, as part of combination schedules or as a single-agent treatment.The authors explored the available data describing the use of oral vinorelbine in NSCLC. PubMed articles and abstracts presented at international conferences were analysed, and relevant trials were reported and discussed. Specific settings, including the treatment of elderly and unfit patients and metronomic schedules including oral vinorelbine, were evaluated. Available pharmacoeconomic data were also assessed.Oral vinorelbine is an appealing agent, particularly as part of combination regimens containing platinum derivatives, although it can have a role as a single-agent treatment as well. Its safety profile is generally favourable and its route of administration is generally preferred by patients receiving chemotherapy. Compared to i.v. vinorelbine and other antineoplastic agents, oral vinorelbine has been reported to be advantageous in terms of cost savings.

Introduction: Despite recent advances with new chemotherapeutic agents and target therapies, the prognosis of NSCLC remains poor. Recent results from clinical trials of immunotherapeutic agents, especially with immune checkpoint inhibitors, make this approach very exciting in NSCLC. Ipilimumab is a monoclonal antibody directed against cytotoxic T-lymphocyte antigen 4 that is able to stimulate the antitumour immune response by promoting T-cell activation. Areas covered: We have reviewed the literature and have described the most important results obtained with ipilimumab in NSCLC in recent trials with a specific focus on its peculiar toxicity profile and pattern of response. Trials ongoing with ipilimumab are also reported. Expert opinion: The results from clinical trials with ipilimumab are promising. Some important issues in the near future will be to identify prognostic and predictive biomarkers to select patients who could benefit from this drug. Further studies are warranted to understand how to combi...

The treatment of advanced non-small cell lung cancer (NSCLC) has been revolutionized by immune checkpoint inhibitors (ICIs). The identification of prognostic and predictive factors in ICIs-treated patients is presently challenging. Circulating tumor cells (CTCs) and cell-free DNA (cfDNA) were evaluated in 89 previously treated NSCLC patients receiving nivolumab. Blood samples were collected before therapy and at the first and second radiological response assessments. CTCs were isolated by a filtration-based method. cfDNA was extracted from plasma and estimated by quantitative PCR. Patients with baseline CTC number and cfDNA below their median values (2 and 836.5 ng from 3 mL of blood and plasma, respectively) survived significantly longer than those with higher values (p = 0.05 and p = 0.04, respectively). The two biomarkers were then used separately and jointly as time-dependent covariates in a regression model confirming their prognostic role. Additionally, a four-fold risk of death for the subgroup presenting both circulating biomarkers above the median values was observed (p &lt, 0.001). No significant differences were found between circulating biomarkers and best response. However, progressing patients with concomitant lower CTCs and cfDNA performed clinically well (p = 0.007), suggesting that jointed CTCs and cfDNA might help discriminate a low-risk population which might benefit from continuing ICIs beyond progression.

e14162 Background: It is well established that an altered host metabolism has an impact on cancer outcome, possibly mediated by several mechanisms, including hyperglicaemia, hyperinsulinemia and presence of chronic inflammation. The aim of our analysis was to evaluate the correlation between host metabolism and clinical outcome in patients with advanced melanoma, kidney and non-small cell lung cancer (NSCLC), treated with immune checkpoint inhibitors (anti-CTLA4, anti PD1 and anti PDL1). Methods: The relationship between presence of type 2 diabetes mellitus (DMII) at baseline and outcome was assessed in 187 patients treated with immune checkpoint inhibitors in two cancer centers. Progression Free Survival (PFS) and Overall Survival (OS) were calculated by Kaplan-Meier estimation; multivariate Cox analysis was performed according to age, gender, BMI (normal < 25 kg/m2, overweight 25-30 kg/m2, obese > 30 kg/m2), type of cancer and line of treatment. Results: One-hundred-sixty-eight patients were available for our analysis. Twenty-eight patients (17%) were diabetic at baseline. Median age was 65 (range 25-80); 83 patients were males (49%); 82 (48%) had advanced melanoma, 83 (49%) NSCLC and 3 (3%) kidney cancer. One-hundred-two (60%) patients had BMI < 25, 51 (30%) were overweight and 16 (10%) were obese. The first line of treatment was immunotherapy in 83 (49%) patients. By univariable analysis median PFS was 4.2 months in non diabetics vs 6.4 in diabetics patients (HR 0.95; 95%CI 0.58-1.58); median OS was 6.17 and 9.1 months, respectively (HR 1.00; 95%CI 0.58-1.75). At multivariable analysis, taking into account DMII, BMI, sex, age, line of treatment and type of cancer, we found that BMI ≤25 was associated with a two fold increase in risk of progression (PD) or death (p = 0.005), whereas patients who received immunotherapy as second or subsequent line had a two fold increase in risk of PD or death (p = 0.003). Conclusions: The results of our analysis show that in patients with advanced cancer treated with immune checkpoint inhibitors, the presence of DMII does not adversely affect the clinical outcome. Conversely, lower BMI was associated with a significantly worse PFS and OS, independently from type of cancer, age and gender. As expected, patients who received immunotherapy in later lines of treatment had a significantly shorter survival.

Although the achievements in the treatment of advanced non-small cell lung cancer (NSCLC) have been translated in improved disease control, response rate and survival, especially in the case of patients with targetable oncogenic drivers, acquired resistance is common after initial benefit; furthermore, primary resistance can occasionally be observed. Due to its clinical implications, the management of treatment-resistant NSCLC is a top topic of the current research, and many efforts are being put in the study of the mechanisms at the base of resistance and in the development of effective therapeutic countermeasures. Areas covered: This review aims at identifying the most relevant novel chemical therapies designed to overcome resistance in NSCLC, including recently approved agents, as well as compounds in clinical development. Expert opinion: An improved knowledge of the mechanisms causing resistance to treatments in NSCLC translates into effective innovative chemical therapies able to overcome such occurrence, and the paradigms of this progress are represented by novel inhibitors of the epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK); however, the study of novel systemic therapies in this setting is challenging, and further efforts in this setting are highly needed.

Malignant pleural mesothelioma (MPM) is an uncommon, aggressive cancer, derived from pleural mesothelial cells, that has a close relationship to asbestos exposure. To date, MPM prognosis is poor and very few treatment options are available for both localized and advanced MPM.The standard of care is still chemotherapy with platinum derivates and antifolate agents. In the last few years, several new agents have been studied on the basis of mesothelioma carcinogenesis and invasiveness mechanisms; however, the recent results are poor and few drugs have been tested in phase III trials because of toxicity or because they did not improve patient outcomes. The aim of this review is to focus on the current available treatment for MPM through the analysis of the results comes from the phase III trials and to discuss the future perspectives in the pathogenesis, diagnosis and treatment.Many compounds are currently under investigation in different subsets of patients. Interesting data have come from preliminary studies on immunotherapy, but randomized studies are needed to confirm the preliminary positive results of this new strategy. A better comprehension of MPM pathogenesis should be obtained to improve and develop new diagnostic tools and target therapies.
