Introduction: Cardiovascular toxicity of immunotherapy represents an underreported but potentially fatal side effect. A relatively high incidence of pericardial disease has been noticed in patients with non-small cell lung cancer (NSCLC)., Methods: We retrospectively analyzed a population of patients with advanced NSCLC receiving immune checkpoint inhibitors (ICIs) looking for the presence of pericardial effusion at baseline or during treatment. The study population was compared with a control group treated with chemotherapy. All patients were checked for the presence of concomitant pleural effusion., Results: We identify 60 patients (36 male/24 female, median age 70 years [range 43-81]). Prevalent histology was adenocarcinoma (65%) followed by squamous cell carcinoma (28%) and large cell or not otherwise specified (NOS) carcinoma (7%). Treatment consisted of nivolumab 3 mg/kg every 14 days (52 cases; 45 as second-line and 7 as third-line treatment) or pembrolizumab 200 mg (8 cases; all first-line treatment) for a total of 302 cycles delivered. Four out of 60 patients (6.7%) developed pericardial effusion during treatment, in two cases (3.3%) without concomitant pleural effusion, compared to 2 out of 60 (3.3%) in the control group in one case without concomitant pleural effusion (1.6%). Median time of onset was 40 days. Myocarditis was not observed., Conclusion: Our findings confirm pericardial effusion as a relatively frequent side effect of immunotherapy in NSCLC. Clinicians should be aware of this specific toxicity in patients with metastatic NSCLC receiving immunotherapy and refer to a cardiologist for a multidisciplinary approach.

Background/aim: The optimal therapeutic use of metronomic vinorelbine has not yet been defined. We aimed to assess the safety of metronomic oral vinorelbine in first-line treatment of elderly patients with advanced lung cancer who were unfit for polychemotherapy. Progression-free survival, response rate and overall survival were secondary end-points., Patients and Methods: Seventy-six patients received 50 mg of oral vinorelbine three times per week, until disease progression, patient refusal or unacceptable toxicity. Patients were evaluated for response and toxicity after one cycle of chemotherapy. The treatment was considered feasible with a grade 3/4 toxicity rate lower than 20%., Results: Clinical benefit was observed in 50% of patients. Median overall survival was 8.0 months. Grade 1/2 toxicity was observed in 53 patients (69.7%), grade 3 toxicity in eight patients (10.5%). One patient had grade 4 diarrhea., Conclusion: Metronomic oral vinorelbine is safe in elderly patients, allowing for long-term disease stabilization with optimal patient compliance., (Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Background/aim: The management of elderly patients with advanced non-squamous NSCLC includes several strategies., Patients and Methods: Patients (≥70 years) were randomly assigned to bevacizumab (7.5 mg/kg i.v. on day 1) plus gemcitabine (1,200 mg/m 2 i.v. on days 1-8) (arm A) or bevacizumab (7.5 mg/kg i.v.) and cisplatin (60 mg/m 2 i.v.) plus gemcitabine (1,000 mg/m 2 i.v. on days 1-8) (arm B), to independently evaluate treatments. The primary endpoint was progression-free rate at 6 months; secondary endpoints included progression-free survival (PFS) and safety profiles., Results: At 6 months, 5 (11.6%) patients in arm A and 5 patients (12.5%) in arm B were found to be progression-free. Median PFS was 4.8 months in arm A and 6.5 months in arm B, respectively., Conclusion: In our experience, combination of bevacizumab and chemotherapy had encouraging anti-tumor efficacy as first-line therapy in elderly patients with non-squamous NSCLC., (Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Introduction: KRAS oncogene mutations (MUTKRAS) drive resistance to EGFR inhibition by providing alternative signaling as demonstrated in colo-rectal cancer. In non-small cell lung cancer (NSCLC), the efficacy of treatment with EGFR tyrosine kinase inhibitors (EGFR-TKIs) depends on activating EGFR mutations (MUTEGFR). However, inhibition of EGFR may select resistant cells displaying alternative signaling, i.e., KRAS, or restoration of EGFR activity due to additional MUTEGFR, i.e., the c.2369C > T (p.T790MEGFR)., Aim: The aim of this study was to investigate the appearance of MUTKRAS during EGFR-TKI treatment and their contribution to drug resistance., Methods: This study used cell-free circulating tumor DNA (cftDNA) to evaluate the appearance of codon 12 MUTKRAS and p.T790MEGFR mutations in 33 advanced NSCLC patients progressing after an EGFR-TKI., Results: p.T790MEGFR was detected in 11 (33.3%) patients, MUTKRAS at codon 12 in 3 (9.1%) while both p.T790MEGFR and MUTKRAS codon 12 were found in 13 (39.4%) patients. Six patients (18.2%) were KRAS wild-type (WTKRAS) and negative for p.T790MEGFR. In 8 subjects paired tumor re-biopsy/plasma samples were available; the percent concordance of tissue/plasma was 62.5% for p.T790MEGFR and 37.5% for MUTKRAS. The analysis of time to progression (TTP) and overall survival (OS) in WTKRAS vs. MUTKRAS were not statistically different, even if there was a better survival with WTKRAS vs. MUTKRAS, i.e., TTP 14.4 vs. 11.4 months (p = 0.97) and OS 40.2 vs. 35.0 months (p = 0.56), respectively., Conclusions: MUTKRAS could be an additional mechanism of escape from EGFR-TKI inhibition and cftDNA is a feasible approach to monitor the molecular development of drug resistance.

Background: We aimed to explore the use of platinum plus bevacizumab in a real world NSCLC population., Patients and Methods: We retrospectively collected data from patients affected by NS-NSCLC treated with platinum plus bevacizumab across Tuscany., Results: We evaluated 62 (median age: 63.5 [30-77] years) pts. All but one presented with adenocarcinoma and the majority had ECOG PS of 0/1. 17.7% presented with central lesion, 11.3% with brain metastasis, 38.7% with hypertension and 4.8% with mild haemoptysis. We observed a median time to progression (TTP) of 6.5 [2-37] and a median overall survival (OS) of 10.5 [2-39] months. Overall response rate (ORR) was 59.6% with a disease control rate (DCR) of 80.6%. Safety profile was acceptable. We observed five cardiovascular events and two major bleedings with no toxic deaths., Conclusion: Safety and efficacy real world data are consistent with those from clinical trials even in a less selected population.

Background: Metronomic oral vinorelbine could be a safe option for elderly patients with advanced non small cell lung cancer (NSCLC). Metronomic administration of chemotherapy leads to a cytostatic action shifting treatment target from cancer cell to tumor angiogenesis., Methods: 43 chemotherapy naive elderly (≥ 70 yrs) PS 0-2 patients with stage IIIB-IV NSCLC were prospectively recruited. Median age was 80 yrs (M/F 36/7) with predominantly squamous histology. PS distribution was 0-1(16)/2(27) with a median of 3 serious co-morbid illnesses. Study treatment consisted of oral vinorelbine 50mg three times weekly (Monday-Wednesday-Friday) continuously until disease progression, unacceptable toxicity or patient refusal. Primary endpoints were overall response rate (ORR), clinical benefit (CB--disease response plus disease stabilization >12 weeks) and safety. Health-related QoL (HRQoL) was also assessed with FACT-L V4 scoring questionnaire. We conducted an exploratory time-course analysis of VEGF and thrombospondin-1 (TSP1) serum levels in a subgroup of patients., Results: Patients received a median of 5 (range 1-21) cycles with a total of 272 cycles delivered. ORR was 18.6% with 7 partial and 1 complete responses; 17/43 experienced stable disease lasting more than 12 weeks leading to an overall CB of 58.1%. Median time to progression was 5 (range 2-21) and median overall survival 9 (range 3-29) months. Treatment was well tolerated with rare serious toxicity. Regardless of severity main toxicities observed were anemia in 44%, fatigue in 32.4%, and diarrhoea 10.5%. FACT-L v4 scores did not significantly vary during treatment. Baseline VEGF levels were lower and showed a rapid increase during treatment in non-responders pts only while TSP1 levels did not change., Conclusions: Metronomic oral vinorelbine is safe in elderly patients with advanced NSCLC with an interesting activity mainly consisting in long-term disease stabilization coupled with an optimal patient compliance (Eudra-CT 2010-018762-23, AIFA OSS on 26 February 2010).

Background: The combination of oral vinorelbine plus cisplatin has been studied in numerous trials as first-line treatment of patients with non-small cell lung cancer (NSCLC) regardless of histologic subtype. NAVoTrial 01 is the first study that explores this combination specifically in nonsquamous (NS) NSCLC by assessing the feasibility of this doublet (ratio 1:2) in an investigational approach. A reference arm with pemetrexed plus cisplatin was included. Maintenance therapy with single-agent therapy after 4 cycles of combination therapy was included in the study schedules because it reflected a trend in first-line treatment of NSCLC., Patients and Methods: Stage IIIB/IV untreated/relapsed patients with NS NSCLC received a 3-week cycle of pemetrexed 500 mg/m(2) and cisplatin 75 mg/m(2) on day 1 (arm A) or oral vinorelbine 80 mg/m(2) on days 1 and 8 (first cycle 60 mg/m(2)) and cisplatin 80 mg/m(2) on day 1 (arm B). After 4 cycles, patients without disease progression received single-agent maintenance treatment with pemetrexed or oral vinorelbine., Results: Overall, 153 patients were randomized (arm A/arm B: 51/102). Disease control rate (%) for arm A was 76.5 (95% confidence interval [CI], 62.5-87.2) and for arm B it was 75.0 (95% CI, 65.3-83.1), Response rates for arm A were 31.4% (95% CI, 19.1-45.9) and for arm B were 24.0% (95% CI, 16.0-33.6). Median progression-free survival for arm A was 4.3 months (95% CI, 3.8-5.6) and for arm B it was 4.2 months (95% CI, 3.6-4.7). Median survival for arm A was 10.8 months (95% CI, 7.0-16.4) and for arm B it was 10.2 months (95% CI, 7.8-11.9). Main grade 3/4 hematologic toxicities were neutropenia 18.3% (arm A) and 44.0% (arm B), whereas febrile neutropenia was reported in 2% of patients in each arm., Conclusion: Oral vinorelbine and cisplatin had an efficacy in line with that achieved with a standard treatment such as pemetrexed and cisplatin, coupled with an acceptable safety profile., (Copyright © 2014 Elsevier Inc.

Objectives: Customized chemotherapy has several advantages: patients are more likely to be treated with the most effective agents and can be spared the toxicity of ineffective drugs. Based on the literature, excision repair cross complementation group 1 (ERCC1) and ribonucleotide reductase M1 (RRM1) genes represent predictive biomarkers of response to platinum compound and gemcitabine, in NSCLC., Materials and Methods: We had planned a phase II trial (Simon design) to evaluate combination chemotherapy according to single nucleotide polymorphisms (SNPs) of ERCC1 (118T/C and 8092C/A) and RRM1 (-37C/A and -524T/C) in naïve patients affected by advanced NSCLC. ERCC1 and RRM1 SNPs assessment was performed in peripheral blood lymphocytes (PBLs). Combination chemotherapy was selected based on ERCC1 and RRM1 SNPs: we assume that patients with one or two C alleles at position 118 and with one or two A alleles at position 8092 in ERCC1 gene would correspond to Cisplatin non-responder and than with two A alleles at -37 and two C alleles at -524 in RRM1 gene to gemcitabine non-responder. Four schedules were provided: cisplatin+gemcitabine, cisplatin+docetaxel, gemcitabine+docetaxel; docetaxel+vinorelbine. Primary endpoint was overall response (ORR) in the intention-to-treat population., Results: 42 patients were enrolled from January 2010 to November 2011; 40 patients received at least 1 cycle of chemotherapy; median age was 66 years (range: 47-72); 36(90%) had stage IV, 4(10%) IIIB; 23(58%) had adenocarcinoma, 14(35%) squamous carcinoma. Twenty-five (62%) patients received treatment A, 3(8%) treatment B, 11(28%) treatment C, 1(23%) treatment D. ORR was 55%, analysis in squamous patients subgroups showed 71.4% ORR. The median follow-up was 19.7 months, PFS was 23 weeks (95% CI = 15-26) and OS was 40.4 weeks (95% CI = 32-55). Treatment was well tolerated., Conclusion: We observed an increase of ORR in NSCLC patients when they were treated with chemotherapy according to ERCC1 and RRM1 SNPs status., (Copyright © 2013 Elsevier Ireland Ltd.

Purpose: To compare efficacy of pemetrexed versus pemetrexed plus carboplatin in pretreated patients with advanced non-small-cell lung cancer (NSCLC)., Patients and Methods: Patients with advanced NSCLC, in progression during or after first-line platinum-based chemotherapy, were randomly assigned to receive pemetrexed (arm A) or pemetrexed plus carboplatin (arm B). Primary end point was progression-free survival (PFS). A preplanned pooled analysis of the results of this study with those of the NVALT7 study was carried out to assess the impact of carboplatin added to pemetrexed in terms of overall survival (OS)., Results: From July 2007 to October 2009, 239 patients (arm A, n = 120; arm B, n = 119) were enrolled. Median PFS was 3.6 months for arm A versus 3.5 months for arm B (hazard ratio [HR], 1.05; 95% CI, 0.81 to 1.36; P = .706). No statistically significant differences in response rate, OS, or toxicity were observed. A total of 479 patients were included in the pooled analysis. OS was not improved by the addition of carboplatin to pemetrexed (HR, 90; 95% CI, 0.74 to 1.10; P = .316; P heterogeneity = .495). In the subgroup analyses, the addition of carboplatin to pemetrexed in patients with squamous tumors led to a statistically significant improvement in OS from 5.4 to 9 months (adjusted HR, 0.58; 95% CI, 0.37 to 0.91; P interaction test = .039)., Conclusion: Second-line treatment of advanced NSCLC with pemetrexed plus carboplatin does not improve survival outcomes as compared with single-agent pemetrexed. The benefit observed with carboplatin addition in squamous tumors may warrant further investigation.

Background: A recent pooled analysis of randomized trials indicated significant improvement in overall survival from cisplatin-based adjuvant chemotherapy for non-small cell lung cancer (NSCLC), depending on disease stage (only in stages II and III) and PS (≤ 1). Post-operative radiotherapy (RT) is optional for pN2 tumours., Patients and Methods: To evaluate opinions and daily clinical practice of Italian Oncologists about adjuvant treatment of NSCLC, a 46-item questionnaire was delivered via e-mail., Results: Seventy-eight physicians from 68 Centers (out of 98 contacted) returned their questionnaire. Seventy-four, 86, 94, and 78% of them give the indication for adjuvant chemotherapy for stage IIA, IIB, IIIA, and IIIB disease, respectively and 14% in stage IB disease. Stage, PS, and age are taken into consideration evaluating adjuvant approach by 97, 95 and 73%, respectively. Cisplatin-vinorelbine (64%) and cisplatin-gemcitabine (33%), for 4 cycles (81%), are the preferred regimens, while 32% use different regimens. Ninety-two percent indicate RT in pN2 disease and/or positive resection margins. Real Number of patients Needed to Treat (NNT) is probably not completely known/understood and/or used by physicians., Conclusions: A substantial adherence between clinical daily practice in Italy and scientific progresses is described in this paper, even with some discordances regarding the most appropriate adjuvant chemotherapy regimen., (Copyright © 2010 Elsevier Ireland Ltd.

Background: Erlotinib demonstrated significantly prolonged survival versus placebo in patients with advanced NSCLC who had progressed after standard chemotherapy. TRUST is a phase IV trial initiated to provide erlotinib access to patients with advanced NSCLC. We report the interim analysis for patients enrolled in the TRUST trial in Italy., Patients and Methods: Eligible patients had stage IIIB/IV NSCLC and had failed or were unsuitable for chemotherapy. Erlotinib (150 mg/day orally) was given until disease progression or unacceptable toxicity. Patients were monitored monthly., Results: At time of this analysis, data from 651 patients were available. Patient characteristics were: median age 66 years (range 30-87), male 69%, former or current smoker 71%, ECOG PS 0-1 81%, adenocarcinoma histology 52% and stage IV 82%. Erlotinib was administered as first-, second-, third- or other-line in 12, 45, 43 and <1% of patients, respectively. Response rate was 9%, with a disease-control rate of 63%. Median progression-free survival was 15 weeks and was longer in females (p<0.001), patients with adenocarcinoma (p=0.008), those with no smoking history (p<0.001) and patients who experienced skin toxicity (p<0.001). Safety data were available for 609 patients, 35% of whom had at least one adverse event (AE), but only 4% of patients discontinued treatment due to erlotinib-related AEs., Conclusion: This analysis of the Italian TRUST results confirms the activity and favourable safety profile of erlotinib in unselected patients with advanced NSCLC.
