Background Immune checkpoint inhibitors (ICIs) represent an effective cancer immunotherapy yet are associated with immune-related adverse events (irAEs). The aim of this study was to characterize irAEs involving the peripheral nervous system (PNS-irAEs) in a real-world cohort of ICI-treated patients. Methods Cancer patients treated with ICIs between January 2014 and March 2022 were included. Patients with PNS-irAEs were identified and divided into two groups: (1) cranial/peripheral neuropathies and (2) myasthenia gravis (MG) and/or myositis. Clinical characteristics and outcomes, measured with the modified Rankin Scale (mRS), were compared among the two groups. Results Among 920 ICI-treated patients, 20 patients (2.17%) developed a PNS-irAEs. The median latency from ICI exposure was 8.8 weeks and the median time from onset to clinical nadir was 3.5 weeks. Eleven patients developed a neuropathy: polyneuropathy (n = 4), cranial neuropathy (n = 3), small-fiber neuropathy (n = 3), brachial plexopathy (n = 1). Nine patients presented MG and/or myositis: concomitant MG and myositis (n = 6), isolated myositis (n = 2), exacerbation of MG (n = 1). Immunosuppressive treatment and/or ICI withdrawal determined a significant clinical improvement, expressed by a mRS reduction, in the neuropathy group (p = 0.004), but not in the MG/myositis group (p = 0.11). Overall, death due to irAEs occurred in four patients (20%), all with MG/myositis. Compared to patients with neuropathies, those with MG/myositis had a shorter latency onset (p = 0.036), developed more frequently concomitant non-neurologic irAEs (p = 0.028) and showed a higher mortality rate (p = 0.026). Conclusions In our large cohort of ICI-treated patients, 2.17% developed PNS-irAEs. Compared to ir-neuropathies, ir-MG/myositis tend to occur earlier from ICI exposure and present a worse response to treatment and a higher mortality.

Aims: We performed a meta-analysis to assess the relative risk (RR) of all-grade and grade 3–4 hypertransaminasemia in studies comparing immune-based combinations with sunitinib in treatment-naive patients with advanced renal cell carcinoma. Materials & methods: Outcomes of interest included all-grade and grade 3–4 hypertransaminasemia measured as RRs and 95% confidence intervals (CIs). Results: RRs for all-grade hypertransaminasemia were 1.73 (95% CI: 1.25–2.4) and 1.63 (95% CI: 1.25–2.12) in patients receiving immunocombinations and sunitinib, respectively. The pooled RRs for grade 3–4 hypertransaminasemia were 3.24 and 3.04 in patients treated with immunocombinations or sunitinib. Conclusion: Immune-based combinations were associated with higher hypertransaminasemia risk. Physicians should pay attention to these common but overlooked events. Careful monitoring of tolerability remains a crucial need.

The therapeutic algorithm of renal cell carcinoma has been revolutionized by the approval of immunotherapy agents by regulatory agencies. However, objective and durable responses are still not observed in a large number of patients, and prognostic and predictive biomarkers for immunotherapy response are urgently needed. Prognostic models used in clinical practice are based on clinical and laboratory factors (such as hypercalcaemia, neutrophil count or Karnofsky Performance Status), but, with progress in molecular biology and genome sequencing techniques, new renal cell carcinoma molecular features that might improve disease course and outcomes prediction have been highlighted. An implementation of current models is needed to improve the accuracy of prognosis in the immuno-oncology era. Moreover, several potential biomarkers are currently under evaluation, but effective markers to select patients who might benefit from immunotherapy and to guide therapeutic strategies are still far from validation.

The reactivation of telomerase represents a key moment in the carcinogenesis process. Mutations in the central promoter region of the telomerase reverse transcriptase (TERT) gene cause telomerase reactivation in approximately 90% of solid tumors. In some of these, its prognostic and predictive role in response to treatments has already been demonstrated, in others (such as tumors of the genitourinary tract like urothelial carcinoma) data are controversial and the research is still ongoing. In the future, TERT promoter mutations and telomerase activity could have diagnostic, prognostic, and therapeutic applications in many types of cancer.We performed a review the literature with the aim of describing the current evidence on the prognostic and predictive role ofWe described the role of

To describe the biological rationale of peripheral blood cells (PBC)-derived inflammatory indexes and assess the related prognostic scores for patients with advanced non-small cell lung cancer (aNSCLC) treated with immune-checkpoint inhibitors (ICI).Inflammatory indexes based on PBC may indicate a pro-inflammatory condition affecting the immune response to cancer. The lung immune prognostic index (LIPI), consisting of derived neutrophils-to-lymphocyte ratio (NLR) and lactate dehydrogenase, is a validated prognostic tool, especially for pretreated aNSCLC patients, where the combination of NLR and PD-L1 tumour expression might also be predictive of immunotherapy benefit. In untreated high-PD-L1 aNSCLC patients, the Lung-Immune-Prognostic score (LIPS), including NLR, ECOG PS and concomitant steroids, is prognostic, and its modified version might indicate patients with favourable outcomes despite an ECOG PS of 2. NLR times platelets (i.e., SII), included in the NHS-Lung score, might improve the prognostication for combined chemoimmunotherapy. PBC-derived inflammatory indexes and related scores represent accurate, reproducible and non-expensive prognostic tools with clinical and research utility.

Despite significant therapeutic advances, metastatic CRPC (mCRPC) remains a lethal disease. Mutations in homologous recombination repair (HRR) genes are frequent in mCRPC, and tumors harboring these mutations are known to be sensitive to PARP inhibitors. The aim of this study was to verify the technical effectiveness of this panel in the analysis of mCRPC, the frequency and type of mutations in the BRCA1/BRCA2 genes, as well as in the homologous recombination repair (HRR) genes. A total of 50 mCRPC cases were analyzed using a multi-gene next-generation sequencing panel evaluating a total of 1360 amplicons in 24 HRR genes. Of the 50 cases, 23 specimens (46.0%) had an mCRPC harboring a pathogenic variant or a variant of uncertain significance (VUS), whereas in 27 mCRPCs (54.0%), no mutations were detected (wild-type tumors). BRCA2 was the most commonly mutated gene (14.0% of samples), followed by ATM (12.0%), and BRCA1 (6.0%). In conclusion, we have set up an NGS multi-gene panel that is capable of analyzing BRCA1/BRCA2 and HRR alterations in mCRPC. Moreover, our clinical algorithm is currently being used in clinical practice for the management of patients with mCRPC.

Circadian rhythm regulates cellular differentiation and physiology and shapes the immune response. Altered expression of clock genes might lead to the onset of common malignant cancers, including Renal Cell Carcinoma (RCC). Data from Cancer Genome Atlas (TCGA) indicate that clock genes PER1-3, CRY2, CLOCK, NR1D2 and RORα are overexpressed in RCC tissues and correlate with patients’ prognosis. The expression of clock genes could finely tune transcription factor activity in RCC and is associated with the extent of immune cell infiltration. The clock system interacts with hypoxia-induced factor-1α (HIF-1α) and regulates the circadian oscillation of mammalian target of rapamycin (mTOR) activity thereby conditioning the antitumor effect of mTOR inhibitors. The stimulation of natural killer (NK) cell activity exerted by the administration of interferon-α, a cornerstone of the first era of immunotherapy for RCC, relevantly varies according to circadian dosing time. Recent evidence demonstrated that time-of-day infusion directly affects the efficacy of immune checkpoint inhibitors in cancer patients. Compounds targeting the circadian clock have been identified and their role in the era of immunotherapy deserves to be further investigated. In this review, we aimed at addressing the impact of clock genes on the natural history of kidney cancer and their potential therapeutic implications.

Aims: We performed a meta-analysis to investigate the predictive value of PD-L1 in metastatic renal cell carcinoma (mRCC) patients receiving immune-based combinations versus sunitinib monotherapy. Materials & Methods: Outcomes of interest included OS and PFS; HRs and their 95% CIs were extracted. Results: The pooled HR for OS was 0.71 (95% CI: 0.61–0.84) and 0.75 (95% CI: 0.68–0.82) in PD-L1-positive and unselected patients, respectively. Similarly, HR for PFS was 0.68 (95% CI: 0.54–0.85) in PD-L1-positive patients and 0.63 (95% CI: 0.50–0.78) in the ITT population, respectively. Conclusion: Slight differences were observed between PD-L1-positive patients and the ITT population, and these findings support the limited role of PD-L1 as predictive biomarkers in this setting.

Immune checkpoint inhibitors (ICIs) have reported unprecedented results in the treatment of metastatic renal cell carcinoma (mRCC) patients, as monotherapy or in combination with other anticancer agents. However, little information is available regarding the association between different clinicopathological features and survival in this setting.We performed a meta-analysis aimed at exploring the predictive value of routinely collected clinicopathological data in randomized controlled trials (RCTs) evaluating ICIs plus tyrosine kinase inhibitors (TKIs) in treatment-naïve patients with mRCC.We retrieved all the relevant RCTs through PubMed/Medline, Cochrane Library, and EMBASE; additionally, proceedings of the main international oncological meetings were also searched for relevant abstracts. Eligible studies included RCTs assessing first-line ICI-TKI versus sunitinib in treatment-naïve mRCC patients; the primary endpoint was overall survival (OS), measured as hazard ratio (HR) with corresponding 95% confidence interval (CI).Overall, three phase III RCTs involving 1769 patients with advanced or metastatic RCC were included. Compared with sunitinib, the ICI-TKI combination significantly decreased the risk of death in patients with Eastern Cooperative Oncology Group performance status (ECOG-PS) 0 (HR, 0.66; 95% CI, 0.57-0.76) and ECOG-PS 1 (HR, 0.64; 95% CI, 0.54-0.77). Similarly, the combination was associated with prolonged OS in patients who were65 yr old (HR, 0.57; 95% CI, 0.49-0.67), in mRCC patients ≥65 yr old (HR, 0.75; 95% CI, 0.61-0.90), as well as in male (HR, 0.66; 95% CI, 0.56-0.78) and female (HR, 0.66; 95% CI, 0.52-0.83) patients.According to our results, the magnitude of benefit of the ICI-TKI combination over sunitinib monotherapy in treatment-naïve mRCC patients was consistent across the clinicopathological subgroups. Despite the limitations affecting the analysis, we believe that the results of the current meta-analysis could assist clinicians and researchers in the design and interpretation of future clinical trials on combination therapies in this setting.First-line combinations of an immune checkpoint inhibitor plus a tyrosine kinase inhibitor improved survival in metastatic renal cell carcinoma (mRCC) patients. This survival benefit was consistent across all subgroups of mRCC patients irrespective of clinicopathological features such as patient performance status, age65 and ≥65 yr, and male and female gender.

Background: Obesity has been associated with improved response to immunotherapy in cancer patients. We investigated the role of body mass index (BMI) in patients from the ARON-1 study (NCT05287464) treated by dual immuno-oncology agents (IO+IO) or a combination of immuno-oncology drug and a tyrosine kinase inhibitors (TKI) as first-line therapy for metastatic renal cell carcinoma (mRCC). Patients and methods: Medical records of patients with documented mRCC treated by immuno-oncology combinations were reviewed at 47 institutions from 16 countries. Patients were assessed for overall survival (OS), progression-free survival (OS), and overall clinical benefit (OCB), defined as the sum of the rate of partial/complete responses and stable disease. Univariate and multivariate analyses were used to explore the association of variables of interest with survival. Results: A total of 675 patients were included; BMI was >25 kg/m2 in 345 patients (51%) and was associated with improved OS (55.7 vs. 28.4 months, P < .001). The OCB of patients with BMI >25 kg/m2 versus those with BMI ≤25 kg/m2 was significantly higher only in patients with nonclear cell histology (81% vs. 65%, P = .011), and patients with liver metastases (76% vs. 58%, P = .007), Neutrophil to lymphocyte ratio >4 (77% vs 62%, P = .022) or treated by nivolumab plus ipilimumab (77% vs. 64%, P=.044). In the BMI ≤25 kg/m2 subgroup, significant differences were found between patients with NLR >4 versus ≤4 (62% vs. 82%, P = .002) and patients treated by IO+IO versus IO+TKIs combinations (64% vs. 83%, P = .002). Conclusion: Our study suggests that the prognostic significance and the association of BMI with treatment outcome varies across clinico-pathological mRCC subgroups.

Context Immune checkpoint inhibitors (ICIs) have reported durable responses in selected groups of patients with metastatic urothelial carcinoma (mUC). However, identification of biomarkers predictive of response to ICIs remains an unmet need in mUC management, and the role of programmed cell death ligand 1 (PD-L1) expression remains controversial. Objective In this systematic review and meta-analysis, we aimed at assessing the predictive value of PD-L1 in mUC patients receiving first-line ICIs as monotherapy or in combination with other anticancer agents across randomized controlled clinical trials (RCTs). Evidence acquisition We retrieved all the relevant RCTs through PubMed/Medline, Cochrane library, and EMBASE; proceedings of the main international oncological meetings were also searched for relevant abstracts. Eligible studies included RCTs evaluating ICIs versus chemotherapy in PD-L1–positive mUCs; the primary endpoint was overall survival (OS). Evidence synthesis Three phase III trials matched our eligibility criteria; a total of 2237 PD-L1–positive mUC patients (ICIs: 1125; chemotherapy: 1112) were included in the analysis. Compared with chemotherapy, ICIs were associated with higher OS in PD-L1–positive patients (hazard ratio [HR] 0.86, 95% confidence interval [CI] 0.78–0.96; p = 0.007); conversely, no differences were observed in the PD-L1–negative patient population (HR 1.03, 95% CI 0.89–1.19; p Conclusions Compared with standard chemotherapy, our results suggested a survival benefit in PD-L1–positive mUC patients receiving ICIs; conversely, no benefit was observed in patients with PD-L1–negative disease. Although this systematic review and meta-analysis should be interpreted with caution due to several issues, our results highlight the need for reliable predictive biomarkers of response to ICIs, providing a benchmark for future studies in this setting. Patient summary Despite immune checkpoint inhibitors (ICIs) having revolutionized the treatment landscape of metastatic urothelial carcinoma (mUC), an important percentage of patients do not experience clinical benefit or durable responses. Identification of reliable biomarkers of response to ICIs remains a mandatory need in mUC management, and further efforts are needed to standardize the assessment of programmed cell death ligand 1 in urothelial carcinoma.

The gold standard of medical therapy for advanced prostate cancer is based on the use of androgen-receptor inhibitors and taxane-based chemotherapy. Several new agents, such as enzalutamide, apalutamide, darolutamide and abiraterone, are now approved and currently used in clinical practice.We present a review of the literature on the current state of the art on the use of androgen receptors inhibitors for the treatment of castration-resistant prostate cancer. We also provide an update on recent significant progress and ongoing clinical trials, and discuss the underlying cancer biology of castration resistance.The advent of second-generation androgen receptor inhibitors has radically changed the therapeutic landscape of advanced prostate cancer. Novel strategies targeting the androgenic signaling pathway are being evaluated in order to overcome resistance mechanisms, to optimize the sequence of drugs currently available and to develop new combinational approaches to improve survival outcomes of advanced prostate cancer patients. New clinical trials, predictive biomarkers research, and real-world experience may further improve clinical outcomes and guide clinicians in the decision-making process.

Immune checkpoint inhibitors (ICIs) represent the standard of care as first- or second-line treatment in patients with renal cell carcinoma (RCC). Proton pump inhibitors (PPIs) are among the most prescribed drugs worldwide and are known to affect gut microbiota, which is gaining interest in its association with outcomes for patients on ICIs.The aim of this study was to evaluate the impact of PPIs on outcomes in RCC patients receiving immunotherapy.We retrospectively collected data from patients with metastatic RCC who received the combination of ipilimumab and nivolumab for first-line treatment (Cohort 1) or single-agent nivolumab for second-line or third-line treatment (Cohort 2) from five international centers with expertise in the treatment of RCC. Data about clinicopathological characteristics, PPI use, and outcome on ICIs were collected. Endpoints of the study were objective response rate (ORR), progression-free survival (PFS), and overall survival (OS).Two hundred and eighteen patients (71% male, median age 61 years) were included in the analysis, 62 in Cohort 1 (including 25 patients receiving PPIs) and 156 in Cohort 2 (including 88 patients receiving PPIs), and were followed up for a median of 42 months. In Cohort 1, no difference was observed in ORR (48% vs 57%; p = 0.203), PFS (12.2 vs 8.5 months; p = 0.928), or OS (not reached [NR] vs 27.3 months; p = 0.84). In Cohort 2, no difference was observed in ORR (32% vs 28%; p = 0.538), PFS (6.7 vs 9.0 months; p = 0.799), or OS (16.0 vs 26.0 months; p = 0.324).In patients with RCC, concomitant PPI use did not seem to affect survival outcomes on ICIs, either as combination therapy or monotherapy.

Background/aim We performed a systematic review and meta-analysis to investigate the safety of maintenance with olaparib after platinum-based chemotherapy in cancer patients. Materials and methods Eligible studies included randomized controlled trials (RCTs) regarding the clinical role of olaparib maintenance therapy versus placebo in BRCA-mutated, advanced cancers. Safety profile from each selected study was investigated for all-grade and G3-G4 haematological and non-haematological adverse drug events (ADEs). Results Four RTCs that involved 1099 patients were included in the analysis. Overall incidences of all-grade and G3-4 ADEs in olaparib group were 97.6% and 41%, respectively. Patients treated with maintenance olaparib showed higher risk of all-grade and G3-G4 anaemia, all-grade neutropenia and thrombocytopenia. Moreover, all-grade and G3-G4 fatigue, all-grade vomiting, diarrhoea, nausea and decreased appetite were more common in the olaparib group compared to placebo. Conclusion Despite an increased risk and incidence of several haematological and non-haematological toxicities, olaparib is a relatively safe agent for the treatment of advanced solid tumors. Prompt identification of ADEs is mandatory to avoid therapy discontinuation and optimize treatment.

Introduction: In the evolving treatment scenario of metastatic renal cell carcinoma, cabozantinib is gaining increasing attention, presenting as a cornerstone therapy, both as a monotherapy and in combination with immune-checkpoint inhibitors.Areas covered: In this review, the authors explore the role of cabozantinib in the treatment of metastatic clear cell and non-clear cell renal cell carcinoma, presenting data from the most recent clinical trials and investigating ongoing studies. They, furthermore, evaluate the pharmacokinetic, pharmacodynamic, and immunomodulatory effect of cabozantinib, as well as underlining the tolerability profile and patients' quality of life.Expert opinion: Cabozantinib's administration as a single agent is restricted to intermediate- and poor-risk patients (according to IMDC criteria). The further advent of anti-VEGF-receptor tyrosine kinase inhibitors combined with immune checkpoint inhibitor regimens (such as pembrolizumab + axitinib) has allowed to expand the use of cabozantinib, leading to its combination with nivolumab. In the next few years, more information is required to look for the application of cabozantinib-based combinations as a later-line approach in metastatic RCC patients, beside their use in the first-line setting.

Several novel androgen receptor (AR)-inhibitors have been introduced for nonmetastatic castration-resistant prostate cancer (nmCRPC) treatment, with the improvement of survival outcomes which need to be balanced against the risk of adverse events. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating enzalutamide, apalutamide and darolutamide in nmCRPC patients, to assess overall survival (OS), incidence and risk of adverse drug events, adverse-events-related death and adverse-events-related treatment discontinuation. We selected three RCTs (SPARTAN, PROSPER and ARAMIS). New hormonal agents administration resulted in better OS, despite the increased risk of several any grade and grade 3-4 adverse events. In the decision-making process, careful evaluation of expected adverse events, patients' comorbidities and maintenance of quality of life are mandatory.

Aim We performed a systematic review and meta-analysis to evaluate the role of platinum-based adjuvant chemotherapy (AC) in upper tract urothelial carcinoma. Materials methods Eligible studies were identified using Pubmed/Medline, Cochrane library, Embase and meeting abstracts. Outcomes of interest included: overall survival (OS), cancer-specific survival (CSS) and disease-free survival (DFS). Results Platinum-based AC was associated with improved DFS, while the benefit in OS and CSS was not statistically significant compared to observation. Conversely, platinum-based AC showed a modest OS benefit in an analysis combing multivariable HRs with estimated HRs from Kaplan-Meier curves. Conclusion Our results suggest that platinum-based AC is associated with improved DFS and a modest OS benefit in patients with locally advanced urothelial carcinomas.

Background: Renal cell carcinoma with sarcomatoid differentiation is a highly aggressive form of kidney cancer. Objective: We aimed to analyze the outcomes of patients treated with cabozantinib for metastatic renal cell carcinoma with sarcomatoid features. Methods: We retrospectively collected data from 16 worldwide centers. Overall survival and progression-free survival were analyzed using Kaplan–Meier curves. Cox proportional models were used for univariate and multivariate analyses. Results: We collected data from 66 patients with metastatic sarcomatoid renal cell carcinoma receiving cabozantinib as second-line (51%) or third-line (49%) therapy. The median progression-free survival from the start of cabozantinib was 7.59 months (95% confidence interval [CI] 5.75−17.49) and was longer in male patients (8.81 vs 5.95 months, p = 0.042) and in patients without bone metastases (7.59 vs 5.11 months, p = 0.010); the median overall survival was 9.11 months (95% CI 7.13−23.80). At the multivariate analysis, female sex (hazard ratio = 1.81; 95% CI 1.02−3.37,p = 0.046), bone metastases (hazard ratio = 2.62; 95% CI 1.34−5.10, p = 0.005), and International Metastatic Renal Cell Carcinoma Database Consortium criteria (hazard ratio = 3.04; 95% CI 1.54−5.99, p = 0.001) were significant predictors of worse overall survival. Conclusions: Our data show that cabozantinib is active in pretreated patients with sarcomatoid renal cell carcinoma. Biomarkers are needed in this field to select patients for multi-kinase inhibitors or other options.

Introduction The incidence of kidney cancer is increasing; it could be counteracted with new ways to predict and detect it. We aimed to implement an artificial neural network in order to predict new cases of renal-cell carcinoma (RCC) in the population using population rate, obesity, smoking incidence, uncontrolled hypertension, and life expectancy data in the United States. Patients and Methods Statistics were collected on US population numbers, life expectancy, obesity, smoking, and hypertension. We used MATLAB R2018 (MathWorks) software to implement an artificial neural network. Data were repeatedly and randomly divided into training (70%) and validation (30%) subsets. Results The number of new RCC cases will grow from 44,400 (2020) to 55,400 (2050), an increase of +24.7%. Our data show that preventing hypertension would have the greatest impact on reduction of the incidence, estimated at −775 and −575 cases per year in 2020 and in 2030, respectively. The prevention of obesity and smoking would have a more limited impact, estimated at −64 and −180 cases per year in 2020 and in 2030, respectively, for obesity, and −173 and −21 cases per year in 2020 and in 2030, respectively, for smoking. Conclusions Our predictions underline the need for accurate studies on RCC-related risk factors to reduce the incidence.

The American Joint Committee of Cancer (AJCC) tumor-node-metastasis (TNM) classification, with its periodical updates and modifications, has represented and still represents the basis of cancer staging. The historical, long-standing limitations of anatomic-based TNM staging have been recently "threatened" by the impressive amount of data derived from molecular analyses, which have led to an unprecedented level of understanding of cancer genomics. In fact, current era of personalized oncology has witnessed important efforts towards the integration between clinical, anatomical and molecular features; however, despite the promises, personalized oncology faces many obstacles, due to the complex relationship between tumor biomarkers, previously unknown cancer subtypes and clinical and anatomical characteristics. With regard to urothelial carcinoma (UC), the characterization of tumors in large cohorts of patients has provided important information concerning genetic alterations, revealing the presence of biologically relevant subtypes of UC. In the current review, we will provide an overview regarding this recent "translation" from the anatomic-based TNM to a novel horizon, aiming at further "tailoring" personalized oncology, especially focusing on recently published data about the molecular landscape of UC with its therapeutic and prognostic implications.
