Objectives: This study aimed to evaluate the predictive and prognostic factors in clinical stage I, anaplastic lymphoma kinase (ALK)-rearranged lung adenocarcinoma following radical surgery. Additionally, it sought to compare these factors with an external cohort of ALK wild-type patients., Methods: A multicentric, retrospective, case-control analysis was conducted on patients with clinical T1-2 N0 ALK-rearranged lung adenocarcinoma who underwent anatomical resection and radical lymphadenectomy. Data were collected from 5 high-volume oncological centres. An external cohort of ALK wild-type patients was also analysed for comparison. Survival analyses were performed using the Kaplan-Meier method, and multivariable Cox regression analysis was used to identify prognostic factors., Results: From January 2016 to December 2022, 63 patients with ALK-rearranged lung adenocarcinoma were included. High-grade tumours (G3) significantly associated with upstaging (odds ratio = 3.904, P = 0.04). Disease-free survival (DFS) and overall survival were significantly improved in upstaged patients receiving adjuvant treatment [hazard ratio (HR) = 0.18, P = 0.0042; HR = 0.24, P = 0.0004, respectively]. The solid or micropapillary histological subtypes were independently associated with worse DFS (HR = 3.41, P = 0.022). Comparison with 435 ALK wild-type patients showed worse DFS in the ALK-rearranged group (HR = 2.09, P = 0.0003). ALK-rearranged patients had higher rates of nodal upstaging, systemic and brain recurrences., Conclusions: Clinical T1-2 N0 ALK-rearranged lung adenocarcinoma is an aggressive disease with a specific tropism for lymph nodes and the brain. High-grade tumours are predictive of nodal upstaging. Adjuvant treatment significantly improves DFS and overall survival in upstaged patients, highlighting the need for personalized preoperative staging and post-surgical management in this cohort., (© The Author(s) 2024.

Purpose: The aim of this multi-center, retrospective/prospective cohort observational study was to evaluate outcomes in routine clinical practice of first-line chemo-immunotherapy with cis/carboplatin, pemetrexed and pembrolizumab in patients with advanced non-squamous non-small cell lung cancer (NSCLC) in 33 Italian centers., Methods: The outcome measure was to evaluate overall survival (OS) in a real-world patient population. Secondary endpoints were: progression-free survival (PFS), objective response rate (ORR), duration of response (DoR) and incidence of treatment-related adverse events (AEs)., Results: 1068 patients were enrolled at the time of data cut-off (January 31st, 2023), and 812 (76.0%) belonged to the retrospective cohort. Median age was 66 years (27-85), ECOG PS was ≥ 2 in 91 (8.6%) patients; 254 (23.8%) patients had brain metastases at baseline; 38 (3.6%) patients had tumor with PD-L1 expression ≥ 50%. After a median follow-up of 17.0 months (95% CI, 16.1-17.9), median OS was 16.1 months (95% CI, 14.4-18.8) and PFS was 9.9 months (95% CI, 8.8-11.2). Median DoR (n = 493) was 14.7 months (95% CI, 13.6-17.1). ORR was 43.4% (95% CI, 40.4-46.4). Any-grade AEs occurred in 636 (59.6%) patients and grade ≥ 3 in 253 (23.7%) patients. Most common grade ≥ 3 AEs were neutropenia (6.3%) and anemia (6.3%)., Conclusions: First-line chemo-immunotherapy was effective and tolerable in this large, real-world Italian study of patients with advanced non-squamous NSCLC. Our results were in line with the KEYNOTE-189 registration study, also considering the low number of PD-L1 ≥ 50% patients included in our study., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Lorenzo Belluomini received speakers' fee from Astra-Zeneca, MSD, Roche, BMS, Amgen, Takeda.

Background: Pleural mesothelioma usually presents at an advanced, incurable stage. Chemotherapy with platinum-pemetrexed is a standard treatment. We hypothesised that the addition of pembrolizumab to platinum-pemetrexed would improve overall survival in patients with pleural mesothelioma., Methods: We did this open-label, international, randomised phase 3 trial at 51 hospitals in Canada, Italy, and France. Eligible participants were aged 18 years or older, with previously untreated advanced pleural mesothelioma, with an Eastern Cooperative Oncology Group performance status score of 0 or 1. Patients were randomly assigned (1:1) to intravenous chemotherapy (cisplatin [75 mg/m 2 ] or carboplatin [area under the concentration-time curve 5-6 mg/mL per min] with pemetrexed 500 mg/m 2 , every 3 weeks for up to 6 cycles), with or without intravenous pembrolizumab 200 mg every 3 weeks (up to 2 years). The primary endpoint was overall survival in all randomly assigned patients; safety was assessed in all randomly assigned patients who received at least one dose of study therapy. This trial is registered with ClinicalTrials.gov, NCT02784171, and is closed to accrual., Findings: Between Jan 31, 2017, and Sept 4, 2020, 440 patients were enrolled and randomly assigned to chemotherapy alone (n=218) or chemotherapy with pembrolizumab (n=222). 333 (76 %) of patients were male, 347 (79%) were White, and median age was 71 years (IQR 66-75). At final analysis (database lock Dec 15, 2022), with a median follow-up of 16·2 months (IQR 8·3-27·8), overall survival was significantly longer with pembrolizumab (median overall survival 17·3 months [95% CI 14·4-21·3] with pembrolizumab vs 16·1 months [13·1-18·2] with chemotherapy alone, hazard ratio for death 0·79; 95% CI 0·64-0·98, two-sided p=0·0324). 3-year overall survival rate was 25% (95% CI 20-33%) with pembrolizumab and 17% (13-24%) with chemotherapy alone. Adverse events related to study treatment of grade 3 or 4 occurred in 60 (27%) of 222 patients in the pembrolizumab group and 32 (15%) of 211 patients in the chemotherapy alone group. Hospital admissions for serious adverse events related to one or more study drugs were reported in 40 (18%) of 222 patients in the pembrolizumab group and 12 (6%) of 211 patients in the chemotherapy alone group. Grade 5 adverse events related to one or more drugs occurred in two patients on the pembrolizumab group and one patient in the chemotherapy alone group., Interpretation: In patients with advanced pleural mesothelioma, the addition of pembrolizumab to standard platinum-pemetrexed chemotherapy was tolerable and resulted in a significant improvement in overall survival. This regimen is a new treatment option for previously untreated advanced pleural mesothelioma., Funding: The Canadian Cancer Society and Merck & Co., Competing Interests: Declaration of interests MP has received grants for research to institution from AstraZeneca and Roche; payment for educational events from Astellas, Pfizer, and AstraZeneca; and received drugs for research from Roche and AstraZeneca.

The use of neoadjuvant or perioperative anti-PD(L)1 was recently tested in multiple clinical trials. We performed a systematic review and meta-analysis of randomised trials comparing neoadjuvant or perioperative chemoimmunotherapy to neoadjuvant chemotherapy in resectable NSCLC. Nine reports from 6 studies were included. Receipt of surgery was more frequent in the experimental arm (odds ratio, OR 1.39) as was pCR (OR 7.60). EFS was improved in the experimental arm (hazard ratio, HR 0.55) regardless of stage, histology, PD-L1 expression (PD-L1 negative, HR 0.74) and smoking exposure (never smokers, HR 0.67), as was OS (HR 0.67). Grade > = 3 treatment-related adverse events were more frequent in the experimental arm (OR 1.22). The experimental treatment improved surgical outcomes, pCR rates, EFS and OS in stage II-IIIB, EGFR/ALK negative resectable NSCLC; confirmatory evidence is warranted for stage IIIB tumours and with higher maturity of the OS endpoint., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: DM: none.

Background: Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. In this study we aim to analyze the upstaging rate in patients with clinical stage I NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy., Methods: Patients who underwent lobectomy and systematic lymphadenectomy for clinical stage I NSCLC were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines., Results: A total of 297 patients were included in the study. 159 patients were female, and the median age was 68 (61 - 73). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the number of resected lymph nodes and micropapillar/solid adenocar-cinoma subtype. This result was confirmed in the multivariate analysis with a OR= 2.545 (95%CI 1.136-5.701; p=0.02) for the number of resected lymph nodes and a OR=2.717 (95%CI 1.256-5.875; p=0.01) for the high-grade pattern of adenocarcinoma., Conclusion: Our results showed that in a homogeneous cohort of patients with clinical stage I NSCLC, the number of resected lymph nodes and the histological subtype of adenocarcinoma can significantly be associated with nodal metastasis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Gallina, Marinelli, Tajè, Forcella, Alessandrini, Cecere, Fusco, Visca, Sperduti, Ambrogi, Cappuzzo, Melis and Facciolo.)

Background: Molecular Tumor Boards (MTB) operating in real-world have generated limited consensus on good practices for accrual, actionable alteration mapping, and outcome metrics. These topics are addressed herein in 124 MTB patients, all real-world accrued at progression, and lacking approved therapy options., Methods: Actionable genomic alterations identified by tumor DNA (tDNA) and circulating tumor DNA (ctDNA) profiling were mapped by customized OncoKB criteria to reflect diagnostic/therapeutic indications as approved in Europe. Alterations were considered non-SoC when mapped at either OncoKB level 3, regardless of tDNA/ctDNA origin, or at OncoKB levels 1/2, provided they were undetectable in matched tDNA, and had not been exploited in previous therapy lines., Results: Altogether, actionable alterations were detected in 54/124 (43.5%) MTB patients, but only in 39 cases (31%) were these alterations (25 from tDNA, 14 from ctDNA) actionable/unexploited, e.g. they had not resulted in the assignment of pre-MTB treatments. Interestingly, actionable and actionable/unexploited alterations both decreased (37.5% and 22.7% respectively) in a subset of 88 MTB patients profiled by tDNA-only, but increased considerably (77.7% and 66.7%) in 18 distinct patients undergoing combined tDNA/ctDNA testing, approaching the potential treatment opportunities (76.9%) in 147 treatment-naïve patients undergoing routine tDNA profiling for the first time. Non-SoC therapy was MTB-recommended to all 39 patients with actionable/unexploited alterations, but only 22 (56%) accessed the applicable drug, mainly due to clinical deterioration, lengthy drug-gathering procedures, and geographical distance from recruiting clinical trials. Partial response and stable disease were recorded in 8 and 7 of 19 evaluable patients, respectively. The time to progression (TTP) ratio (MTB-recommended treatment vs last pre-MTB treatment) exceeded the conventional Von Hoff 1.3 cut-off in 9/19 cases, high absolute TTP and Von Hoff values coinciding in 3 cases. Retrospectively, 8 patients receiving post-MTB treatment(s) as per physician's choice were noted to have a much longer overall survival from MTB accrual than 11 patients who had received no further treatment (35.09 vs 6.67 months, p = 0.006)., Conclusions: MTB-recommended/non-SoC treatments are effective, including those assigned by ctDNA-only alterations. However, real-world MTBs may inadvertently recruit patients electively susceptible to diverse and/or multiple treatments., (© 2023. BioMed Central Ltd., part of Springer Nature.)

KRAS G12C mutations are found in about 12-13% of LUAD samples and it is unclear whether they are associated with worse survival outcomes in resected, stage I LUAD. We assessed whether KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours and to KRAS wild-type tumours in a cohort of resected, stage I LUAD (IRE cohort). We then leveraged on publicly available datasets (TCGA-LUAD, MSK-LUAD 604 ) to further test the hypothesis in external cohorts. In the stage I IRE cohort we found a significant association between the KRAS-G12C mutation and worse DFS in multivariable analysis (HR: 2.47). In the TCGA-LUAD stage I cohort we did not find statistically significant associations between the KRAS-G12C mutation and DFS. In the MSK-LUAD 604 stage I cohort we found that KRAS-G12C mutated tumours had worse RFS when compared to KRAS-nonG12C mutated tumours in univariable analysis (HR 3.5). In the pooled stage I cohort we found that KRAS-G12C mutated tumours had worse DFS when compared to KRAS-nonG12C mutated tumours (HR 2.6), to KRAS wild-type tumours (HR 1.6) and to any other tumours (HR 1.8); in multivariable analysis, the KRAS-G12C mutation was associated with worse DFS (HR 1.61). Our results suggest that patients with resected, stage I LUAD with a KRAS-G12C mutation may have inferior survival outcomes.., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Immune checkpoint inhibitors have activity in mesothelioma. IND.227 was a phase 2 trial (120 patients planned) comparing progression-free survival of standard platinum and pemetrexed (CP) versus CP + pembrolizumab (pembro) versus pembro. Accrual to the pembro arm was discontinued on the basis of interim analysis (IA-16 wk disease control rate). CP + pembro was tolerable, with progression-free survival similar between arms and median survival and overall response rate higher than those of CP alone (19.8 mo [95% confidence interval or CI: 8.4-41.36] versus 8.9 mo [95% CI: 5.3-12.8] and 47% [95% CI: 24%-71%] versus 19% [95% CI: 5%-42%], respectively). The subsequent phase 3 trial has completed accrual; results are expected in 2023., (Copyright © 2023 International Association for the Study of Lung Cancer. Published by Elsevier Inc.

Aims: The minimally invasive procedures used in the diagnostic workup of patients with advanced non-small cell lung cancer (NSCLC) often provide poor yields of pathological material suitable for molecular analyses. Not infrequently, the DNA yield from small biopsies/cytological samples is insufficient for the assessment of genomic biomarkers that inform personalised therapies. The Idylla EGFR mutation test (IEMT) has been specifically designed to process formalin-fixed paraffin-embedded sections without requiring preliminary DNA extraction.This study aims to evaluate the diagnostic accuracy of IEMT when used to analyse archival histopathology material. More specifically, our objective was to establish whether or not different staining procedures could affect assay performance., Methods: Twenty NSCLC samples were selected accordingly to EGFR mutational status. To mimic archived stained material, sections were subjected to H&E staining, fluorescent in situ hybridisation analyses or immunodetection by immunohistochemistry before being processed for IEMT., Results: Parallel assessment of EGFR mutational status by IEMT on stained sections and next-generation sequencing on DNA yielded a concordant result in 50 out of 60 tests (83.3%). The discoloration of H&E of the archived sample was found to be the optimal procedure to highlight all the actionable alterations of EGFR ., Conclusions: IEMT can provide remarkable diagnostic accuracy for the assessment of EGFR mutational status also when the only source of pathological material available for molecular analyses is represented by H&E stained sections. Ad hoc supervision by a qualified molecular biologist is in any case recommended., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

The approval of osimertinib for adjuvant treatment of stage I-II-III EGFR -mutated NSCLC (early stage) represents a paradigm shift, raising the question of whether other genotype-matched therapeutics approved for advanced-stage NSCLC can also provide clinical benefit in the adjuvant setting. However, there is a paucity of real-world data on the prevalence of actionable genomic alterations (GAs) in early-stage NSCLC. We used next-generation sequencing, complemented by immunohistochemistry and fluorescence in situ hybridization, to screen our single-institution cohort of 1961 NSCLC consecutive cases for actionable molecular targets. The prevalence of actionable GAs was comparable in early versus advanced-stage NSCLC, the only exception being KRAS mutations (more frequent in early-stage cases). Consistent with advanced-stage tumors being more aggressive, co-occurrence of TP53 and EGFR GAs as well as copy number gains were less frequent in early-stage tumors. EGFR mutations and high expression of PD-L1 were inversely associated, whereas KRAS mutations and high PD-L1 reactivity showed positive association. Recapitulating advanced-stage tumors, early-stage NSCLC had the highest share of EGFR mutations in lepidic and acinar subtypes. Resected lepidic tumors contained the highest proportion of the KRAS G12C actionable variant. These results, obtained with routine diagnostic technologies in an unselected clinical setting, provide a significant addition of real-world data in early-stage NSCLC.

Background: The combination of radiotherapy (RT) and programmed death 1 inhibitors seems to increase antitumor immune responses., Objective: To assess the outcome and the role of the best combination sequence, i.e. immunotherapy given before, during, and/or after RT, in patients with non-small cell lung cancer (NSCLC)., Methods: We conducted an observational, retrospective analysis of 95 consecutive patients with advanced NSCLC who received any radiotherapy treatment and nivolumab, as clinically indicated. Median overall survival (OS) and the 95% confidence interval (CI) were estimated with the Kaplan-Meier method. Cox model was used to obtain hazard ratio (HR) and associated 95% CI with statistical inference by log-rank statistic., Results: Median OS was 11.9 months (95% CI, 6.6-17.2). Patients who received radiotherapy during an immune checkpoint inhibitor treatment started more than 60 days before showed a better outcome than patients who started immunotherapy over 60 days after RT ending (HR, 2.90 [1.37-6.12], p = 0.005; median OS, 22.4 months vs 8.6 months, p = 0.005). Median progression-free survival was 6.3 months (95% CI, 4.6-8.0)., Conclusions: This study shows that combining irradiation with nivolumab for the treatment of advanced NSCLC leads to improved OS. The optimal time window for the combination of RT and immunotherapy seems to play a critical role for therapeutic antitumor response derived by abscopal effect.

Background: While the thoracotomy approach was considered the gold standard until two decades ago, robotic surgery has increasingly strengthened its role in lung cancer treatment, improving patients’ peri-operative outcomes. In this study, we report our experience in robotic lobectomy for early-stage non-small cell lung cancer, with particular attention to oncological outcomes and nodal upstaging rate. Methods: We retrospectively reviewed patients who underwent lobectomy and radical lymphadenectomy at our Institute between 2016 and 2020. We selected 299 patients who met the inclusion criteria of the study. We analyzed the demographic features of the groups as well as their nodal upstaging rate after pathological examination. Then, we analyzed disease-free and overall survival of the entire enrolled patient population and we compared the same oncological outcomes in the upstaging and the non-upstaging group. Results: A total of 299 patients who underwent robotic lobectomy were enrolled. After surgery, 55 patients reported nodal hilar or mediastinal upstaging. The 3-year overall survival of the entire population was 82.8%. The upstaging group and the non-upstaging group were homogeneous for age, gender, smoking habits, clinical stage, tumor site, tumor histology. The non-upstaging group had better OS (p = 0.004) and DFS (p < 0.0001). Conclusion: Our results show that robotic surgery is a safe and feasible approach for the treatment of early-stage NSCLC, especially for its accuracy in mediastinal lymphadenectomy. The oncological outcomes were encouraging and consistent with previous findings.

Introduction: The standard surgical procedures for patients with early-stage NSCLC is lobectomy-associated radical lymphadenectomy performed by using the thoracotomy approach. In the last few years, minimally invasive techniques have increasingly strengthened their role in lung cancer treatment, especially in the early stage of the disease. Although the lobectomy technique has been accepted, controversy still surrounds lymph node dissection. In our study, we analyze the rate of upstaging early non-small cell lung cancer patients who underwent radical surgical treatment using the robotic and the VATS techniques compared to the standard thoracotomy approach. Methods and Materials: We retrospectively reviewed patients who underwent a lobectomy and radical lymphadenectomy at our Institute between 2010 and 2019. We selected 505 patients who met the inclusion criteria of the study: 237 patients underwent robotic surgery, 158 patients had thoracotomy, and 110 patients were treated with VATS. We analyzed the demographic features between the groups as well as the nodal upstaging rate after pathological examination, the number of dissected lymph nodes and the ratio of dissected lymph nodes to metastatic lymph nodes of the three groups. Results: The patients of the three groups were homogenous with respect to age, sex, and histology. The postoperative major morbidity rate was significantly higher in the thoracotomy group, and hospital stay was significantly longer. The percentage of the mediastinal nodal upstaging rate and the number of dissected lymph nodes was significantly higher in the robotic group compared with the VATS group. The ratio of dissected lymph nodes to metastatic lymph nodes was significantly lower compared with the VATS group and the thoracotomy group. Discussion: The prognostic impact of the R(un) status is still highly debated. A surgical approach that allows better results in terms of resection has still not been defined. Our results show that robotic surgery is a safe and feasible approach especially regarding the accuracy of mediastinal lymphadenectomy. These findings can lead to defining a more precise pathological stage of the disease and, if necessary, to more accurate postoperative treatment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Gallina, Melis, Forcella, Mercadante, Marinelli, Ceddia, Cappuzzo, Vari, Cecere, Caterino, Vidiri, Visca, Buglioni, Sperduti, Marino and Facciolo.)

Background: Coronavirus disease 2019 (COVID-19) has rapidly spread to every country around the world taking on pandemic proportions. Since 8 March 2020, the Italian government ordered a nationwide lockdown with unavoidable social isolation. Healthcare professionals (HCPs) represent the most physically and emotionally involved category. The aim of this study is to assess the social distress among HCPs in Italy., Patients and Methods: In this online, totally anonymous survey, 24 multiple choice questions were posed to medical staff employed in the Italian Healthcare System during the COVID-19 pandemic. Data collection was performed from 30 March to 24 April 2020., Results: A total of 600 HCPs completed the questionnaire. The majority of respondents expressed the fear of being at higher risk of contagion than the general population (83.3%) and the weighty concern of infecting their families (72.5%). An insufficient supply of personal protective equipment (PPE; P = 0.0003) and inadequate training about procedures to follow (P = 0.0092) were seen to significantly coincide with these worries. More than two-thirds declared a change in family organisation, which showed a significant correlation with the concern of infecting their relatives (P < 0.0001)., Conclusions: This is the first Italian survey on social distress among HCPs during the COVID-19 pandemic. The unavailability of PPE, screening procedures and adequate training strongly affected HCPs' emotional status. Although there was a predominance of oncologists (especially from the North of Italy), which impairs the generalisation of our findings, this survey underlined the social impact that this health emergency has had on HCPs., Competing Interests: Disclosure The authors have declared no conflicts of interest., (Copyright © 2021 The Authors.

Background: Platinum-based therapy, combined or not with immune checkpoint inhibitors, represents a front-line choice for patients with non-small-cell lung cancer (NSCLC). Despite the improved outcomes in the last years for this malignancy, only a sub-group of patients have long-term benefit. Excision repair cross-complementation group 1 (ERCC1) has been considered a potential biomarker to predict the outcome of platinum-based chemotherapy in NSCLC. However, the ERCC1 gene is transcribed in four splice variants where the isoform 202 was described as the only one active and able to complex Xeroderma pigmentosum group F-complementing protein (XPF). Here, we prospectively investigated if the active form of ERCC1, as assessed by the ERCC1/XPF complex (ERCC1/XPF), could predict the sensitivity to platinum compounds., Patients and Methods: Prospectively enrolled, patients with advanced NSCLC treated with a first-line regimen containing platinum were centrally evaluated for ERCC1/XPF by a proximity ligation assay. Overall survival (OS), progression-free survival (PFS) and objective response rate (ORR) were analyzed., Results: The absence of the ERCC1/XPF in the tumor suggested a trend of worst outcomes in terms of both OS [hazard ratio (HR) 1.41, 95% confidence interval (CI) 0.67-2.94, P = 0.373] and PFS (HR 1.61, 95% CI 0.88-3.03, P = 0.123). ORR was marginally influenced in ERCC1/XPF-negative and -positive groups [odds ratio (stable disease + progressive disease versus complete response + partial response) 0.87, 95% CI 0.25-3.07, P = 0.832]., Conclusion: The lack of ERCC1/XPF complex in NSCLC tumor cells might delineate a group of patients with poor outcomes when treated with platinum compounds. ERCC1/XPF absence might well identify patients for whom a different therapeutic approach could be necessary., Competing Interests: Disclosure MCG reported personal fees from Merck, Bristol-Myers Squibb, AstraZeneca, Roche, Takeda, Celgene, Pfizer, and GlaxoSmithKline.

Background: Malignant pleural mesothelioma (MPM) is a rare and aggressive disease of the pleura with a dismal prognosis. Distant metastases most commonly occur in the liver, spleen, and thyroid gland. To our knowledge, ovarian metastases have never been described., Case Description: We describe a case of a woman with recurrent malignant pleural mesothelioma presenting a single ovarian metastasis, surgically resected., Conclusions: This case report highlights the importance of using a complete staging protocol in patients with MPM to improve patient management. A whole-body computed tomography (CT) scan with contrast enhancement and possibly positron emission tomography-CT should be performed to identify any distant metastases before deciding on treatment strategy.

In the era of personalized medicine, BRAF mutational assessment is mandatory in advanced-stage melanoma and non-small cell lung cancer (NSCLC) patients. The identification of actionable mutations is crucial for the adequate management of these patients. To date various drugs have been implemented in clinical practice. Similarly, various methods may be adopted for the identification of BRAF mutations. Here, we briefly review the current literature on BRAF in melanoma and NSCLC, focusing attention in particular on the different methods and drugs adopted in these patients. In addition, an overview of the real-world practice in different Italian laboratories with high expertise in molecular predictive pathology testing is provided., (Copyright © 2020 Elsevier B.V.

Clinical data suggest that only a subgroup of non-small cell lung cancer (NSCLC) patients has long-term benefits after front-line platinum-based therapy. We prospectively investigate whether KRAS status and DNA polymerase β expression could help identify patients responding to platinum compounds. Prospectively enrolled, advanced NSCLC patients treated with a first-line regimen containing platinum were genotyped for KRAS and centrally evaluated for DNA polymerase β expression. Overall survival (OS), progression-free survival (PFS), and the objective response rate (ORR) were recorded. Patients with KRAS mutations had worse OS (hazard ratio (HR): 1.37, 95% confidence interval (95% CI): 0.70-2.27). Negative DNA polymerase β staining identified a subgroup with worse OS than patients expressing the protein (HR: 1.43, 95% CI: 0.57-3.57). The addition of KRAS to the analyses further worsened the prognosis of patients with negative DNA polymerase β staining (HR: 1.67, 95% CI: 0.52-5.56). DNA polymerase β did not influence PFS and ORR. KRAS may have a negative role in platinum-based therapy responses in NSCLC, but its impact is limited. DNA polymerase β, when not expressed, might indicate a group of patients with poor outcomes. KRAS mutations in tumors not expressing DNA polymerase β further worsens survival. Therefore, these two biomarkers together might well identify patients for whom alternatives to platinum-based chemotherapy should be used.

Background: Although immunotherapy with immune-checkpoint inhibitors (ICIs) has profoundly changed the therapeutic scenario in the treatment of advanced non-small cell lung cancer (NSCLC), trials of ICIs only enrolled NSCLC patients with common histology. Atezolizumab was approved by the United States Food and Drug Administration (US FDA) in October 2016 and by the European Medicines Agency (EMA) in September 2017 for the treatment of patients with metastatic NSCLC whose disease progressed during or following platinum-containing chemotherapy, regardless of PD-L1 expression., Methods: We designed a single-arm, multicenter, two-stage phase II study and plan to enroll 43 patients. The primary objective of the study is to evaluate the antitumor activity of atezolizumab in advanced NSCLC patients with rare histology subtypes. Patients with prior atezolizumab or ICI treatment and with untreated, symptomatic, or progressing brain metastases will be excluded. The primary endpoint is disease control rate. Secondary objectives are toxicity and safety, overall response rate, progression-free survival, overall survival, and time to progression. Diagnosis of NSCLC with rare histology will be confirmed by central pathology revision, and will include: colloid carcinoma, fetal adenocarcinoma, non-endocrine large cell carcinoma, sarcomatoid carcinoma, salivary gland-type tumor, lymphoepithelioma-like carcinoma, and NUT-nuclear protein in testis carcinoma. Archival tumor tissue is required for correlative studies of PD-L1 expression on tumor cells and tumor infiltrating lymphocytes., Conclusions: Therapeutic options in NSCLC with rare histology subtypes, to be assessed in specifically designed trials, are an unmet need. This trial will help elucidate the role of atezolizumab as a viable option in this setting., Competing Interests: Conflict of interest statement: The authors declare that there is no conflict of interest., (© The Author(s), 2020.)

Among the group of thymic epithelial tumors (TET), thymomas often show either uncertain or explicit malignant biological behavior, local invasiveness, and intrathoracic relapse and are often difficult to manage. From the initial stages, thymic carcinomas tend to show aggressive behavior and extrathoracic spread. Moreover, the interplay of epithelial cells and thymocytes in thymomas causes complex immune derangement and related systemic autoimmune diseases. Due to their rare occurrence and to the limited funding opportunities available for rare tumors, it is challenging to make advances in clinical and translational research in TET. The authors of this paper are all members of a multidisciplinary clinical and research thoracic tumor team. Strong input was given to the team by long-standing expertise in TET in the Pathology Department. In addition, thanks to the collaboration between research units at our Institute as well as to national collaborations, over the last 10 years we were able to perform several tissue-based research studies. The most recent studies focused on microRNA and on functional studies on the thymic carcinoma cell line 1889c. The recent implementation of our biobank now provides us with a new tool for networking collaborative research activities. Moreover, the participation in a worldwide community such as ITMIG (International Thymic Malignancy Interest Group) has allowed us to significantly contribute toward fundamental projects/research both in tissue-based studies (The Cancer Genome Atlas) and in clinical studies (TNM staging of TET). Our achievements derive from constant commitment and long-standing experience in diagnosis and research in TET. New perspectives opened up due to the establishment of national [the Italian Collaborative Group for ThYmic MalignanciEs (TYME)] and European reference networks such as EURACAN, for an empowered joint clinical action in adult solid rare tumors. The challenge we face still lies in the advancement of clinical and basic science in thymic epithelial malignancies., (Copyright © 2020 Melis, Gallo, di Martino, Gallina, Laquintana, Casini, Visca, Ganci, Alessandrini, Caterino, Cecere, Mandoj, Papadantonakis, De Bello, Lattanzio, Palmieri, Garassino, Girard, Conti, Blandino, Fazi, Facciolo, Pescarmona, Ciliberto and Marino.)

Background: Pembrolizumab is the first-line standard of care for advanced non-small cell lung cancer (NSCLC) with a PD-L1 tumour proportion score (TPS) ≥ 50%. Eastern Cooperative Oncology Group performance status (PS) 2 patients may receive pembrolizumab, despite the absence of sustaining evidence., Patients and Methods: GOIRC-2018-01 is a multicentre, retrospective, observational study. PS 2 NSCLC patients with a PD-L1 TPS ≥50% receiving first-line pembrolizumab from June 2017 to December 2018 at 21 Italian institutions were included. Clinical-pathological characteristics were correlated with disease response and survival outcomes; adverse events were recorded. The primary objective was 6-months progression-free rate (6-months PFR)., Results: One hundred fifty-three patients (median age 70 years) were enrolled. At a median follow-up of 18.2 months, median progression-free survival (PFS) and overall survival (OS) were 2.4 (95% confidence interval, 95% CI, 1.6-2.5) and 3.0 months (95% CI 2.4-3.5), respectively. 6-months PFR was 27% (95% CI 21-35%). Patients with a PS 2 determined by comorbidities (n = 41) had significantly better outcomes compared with disease burden-induced PS 2 (n = 112). Indeed, 6-months PFR was 49% versus 19%, median PFS 5.6 versus 1.8 months and OS 11.8 versus 2.8 months, respectively. Additional potential prognostic factors (radiotherapy, antibiotics, steroids received before pembrolizumab) correlated with clinical outcomes. The determinant of PS 2 resulted the only factor independently impacting on both PFS and OS. No toxicity issues emerged., Conclusions: Outcomes of PS 2 NSCLC patients with PD-L1 TPS ≥50% receiving first-line pembrolizumab were globally dismal but strongly dependent on the reason conditioning the poor PS itself., Competing Interests: Conflict of interest statement F.F. declares he has attended editorial activities sponsored by Roche and BMS.

Background: Clinical-pathologic predictors of acquired T790M epidermal growth factor receptor (EGFR) mutation in Caucasian patients with non-small-cell lung cancer (NSCLC) progressing after first-/second-generation tyrosine kinase inhibitors (TKIs) is an open field for research. Similarly, the best time point for T790M detection by liquid or tissue biopsy after disease progression is currently matter of debate., Patients and Methods: This is an observational study at 7 Italian centers enrolling patients with EGFR-mutant NSCLC progressing after first-/second-generation EGFR TKIs, between 2014 and 2018, aiming at comparing baseline clinical-pathologic features and progression patterns in acquired T790M-positive compared with T790M-negative cases., Results: A total of 235 patients received first-line treatment with gefitinib (N = 126; 53%), erlotinib (N = 51; 22%), or afatinib (N = 58; 25%). In 120 (51%) cases, T790M was detected in liquid biopsy, tissue biopsy, or both. Age younger than 65 years (P = .037), the presence of common mutations (P = .004), and better response to first-line TKI (P = .023) were correlated with T790M positivity. T790M detection was associated with higher number of new progressing sites (P = .04), liver progression (P = .002), and a lower frequency of lung metastases (P = .027). When serial liquid biopsies were performed (N = 15), an oligoprogressive disease was correlated with a negative test outcome, whereas systemic progression was observed at the time of T790M positivity., Conclusion: This study on a Caucasian population showed that age, type of EGFR mutation at diagnosis, response to first-line treatment, and peculiar progression pattern are associated with T790M status. Serial liquid biopsy might be useful for treatment selection, especially when tissue rebiopsy is not feasible., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose: Chemotherapy-induced nausea and vomiting (CINV) still represents a common side-effect of chemotherapy, and often, its perception differs between patients and healthcare professionals. The aim of this study was to evaluate the agreement on the perception of CINV and other items among clinicians, patients, and nurses., Methods: This observational prospective study was part of an evaluation program promoted by the Women Against Lung Cancer in Europe (WALCE) Onlus. From August 2015 to February 2016, a survey was administered in 11 oncologic institutions to 188 stage IV lung cancer patients and to their oncologists and nurses during first-line chemotherapy. Our survey investigated 11 aspects: anxiety, mood, weakness, appetite, nausea, vomiting, pain, drowsiness, breath, general condition, and trust in treatments. These items were assessed through Numerical Rating Scale at four consecutive evaluations: at T0 (immediately prior to the first cycle), at T1 (immediately prior to the second cycle), at T2 (immediately prior to the third cycle), and at T3 (immediately prior to the fourth cycle). Clinician versus patient (CvP), nurse versus patient (NvP), and clinician versus nurse (CvN) agreements were estimated applying Weighted Cohen's kappa. A multivariate logistic model and generalized equation estimates were applied to evaluate factors possibly influencing CINV development., Results: The incidence of patients reporting CINV varied from 40% at T0 to 71% at T3. Both CvP and NvP agreement on the investigated items were mainly moderate, slightly increasing over time, and becoming substantial for some items, in particular for NvP. Pre-chemotherapy anxiety in its mild, moderate, and severe manifestations, as well as mild, moderate, and severe anxiety experienced after chemotherapy start, exposed patients to a higher risk of anticipatory and acute/delayed CINV, respectively., Conclusions: Despite clinical staff awareness of patients' status and perceptions, CINV still represents a clinical problem. This study confirms that particular attention should be paid to anxiety due to its key role in CINV development.

Aim: Ceritinib was evaluated within a compassionate use program of Italian patients., Patients & Methods: 70 patients with anaplastic lymphoma kinase-positive crizotinib-refractory advanced non-small-cell lung cancer received ceritinib., Results: Overall response was 40.6%, median progression-free survival was 8.2 months and median survival was 15.5 months. Dose reduction due to treatment-related adverse events occurred in 50.8% of patients starting at 750 mg/day. No significantly different progression-free survival was observed between patients who underwent any time dose reduction (n = 38) versus those who remained on the recommended dose of 750 mg/day (n = 32; p = 0.07)., Conclusion: The efficacy of ceritinib compassionate use program resembled that of clinical trials. Dose reductions and adjustments did not appear to negatively affect clinical outcome.

Non-small-cell lung cancer is a term that encompasses a number of subtypes of lung cancer. In recent years, several intracellular pathways have been studied in order to discover a potential target for novel anticancer therapies such as anaplastic lymphoma kinase (ALK) and reactive oxygen species 1 (ROS1). Increased interest in oncologic treatment research has resulted from the observation that ALK- and ROS1-associated tyrosine kinases show molecular analogies in some of their domains. This discovery led to the hypothesis that target therapy against ALK translocation could have efficacy also in ROS1-positive tumors. Crizotinib is an oral tyrosine kinase inhibitor that binds the ALK tyrosine kinase domain, blocking its function. We report the case of a woman with heavily pretreated metastatic lung adenocarcinoma harboring ROS1 positivity who experienced a prolonged and dramatic clinical benefit from crizotinib therapy.

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.

Lung cancer is the leading cause of cancer related mortality worldwide. Non-small cell lung cancer (NSCLC) accounts for 85% of all cases. Half of the patients at diagnosis of NSCLC are over seventy years old; therefore, the elderly represent a large subgroup of patients affected by advanced NSCLC in our clinical practice. Nevertheless, the elderly are under-represented in clinical trials. Given the fact that old age is frequently associated with several comorbidities, poor general conditions and physiologic reduction in organ function, clinicians must carefully choose the best treatment option for elderly patients with advanced NSCLC, always taking into account the expected risks and benefits. In this paper we perform a review of literature evidence regarding the medical treatment of elderly patients affected by advanced NSCLC, encompassing single-agent chemotherapy, doublet chemotherapy and targeted agents. We conclude that single-agent chemotherapy with a third generation agent (vinorelbine, taxanes, gemcitabine) represents a valid treatment option for elderly patients who are not eligible for a combination chemotherapy due to clinical features such as comorbidities, poor performance status and inadequate organ function. Platinum-based doublet chemotherapy shows similar efficacy in elderly patients as compared to their younger counterpart, despite greater treatment related toxicity and it is indicated in elderly patients with ECOG PS: 0-2, adequate organ function and no major comorbidities. Elderly patients affected by epidermal growth factor receptor (EGFR) mutated NSCLC benefit mostly from a tyrosine kinase inhibitor of EGFR (erlotinib, gefitinib) which is associated with a good toxicity profile. Currently there are no available data to strongly support the use of bevacizumab in combination with first line chemotherapy in the treatment of older adults. Elderly patients affected by NSCLC harboring the EML4-ALK translocation could benefit mostly from a treatment with an oral inhibitor of such a rearrangement (crizotinib)., (Copyright © 2013 Elsevier Inc.

Background: The number of resected lymph-nodes (#RNs) has proven prognostic in breast and colorectal cancer. Here we evaluated its prognostic impact in a series of resected NSCLC patients., Methods: A panel of established prognostic factors plus (1) #RNs or (2) the ratio between the number of metastatic nodes and #RNs (NR) were correlated to overall- (OS), cancer-specific- (CSS), and disease-free-survival (DFS), using the Cox-model. Risk-classes according to hazard ratios (HR) were generated. Internal and external validation was accomplished., Results: A dataset of 415 resected NSCLC patients was retrieved. At multivariate analysis, #RNs and NR were independent factor for longer OS, CSS and DFS (p<0.0001). Patients with a #RNs>10 (identified optimal cut-off) had a statistically significant OS (p=0.02) and DFS (p=0.0005) benefit. In node-positive patients, a NR<9% significantly correlated with better outcome. Stratification into High-, Medium-, and Low-Risk classes, based on High- (HRFs: stage, N-status, age, #RNs) and Intermediate-Risk Factors (IRFs: sex, grading, histology), efficiently predicted outcomes (p<0.0001). The risk class model performance was externally validated in and independent dataset of 297 patients., Conclusions: These results contribute to complete the panel of prognostic factors for resected NSCLC. A prospective larger validation and comparison with molecular prognostic tools is warranted.

Aim: Survivin is a member of the inhibitors of apoptosis (IAP) gene family that acts through pathways different from those involving the bcl-2 family. Largely undetectable in normal adult tissues, survivin is deregulated in most human cancers including non-small-cell lung cancer (NSCLC) and may represent a tumor marker with prognostic and therapeutic implications. Aim of our study was to determine the prognostic role of survivin as an apoptosis-related biomarker in a series of resected NSCLC patients., Methods: A retrospective series of resected NSCLC patients were retrieved from the files of the Regina Elena National Cancer Institute. Survivin was detected by immunohistochemistry (IHC) using a polyclonal antibody. Survivin displayed two kinds of immunoreactivity: (i) a diffuse cytoplasmic staining and (ii) a distinct nuclear staining. A score-scale to distinguish positive (score 1-2) vs. negative (score 0) pattern was applied. Clinical and biological (nuclear and cytoplasmic survivin staining) covariables were screened for a prognostic relationship with overall survival (OS) and disease-free survival (DFS) into the univariate and multivariate analyses., Results: Data referring to 116 NSCLC patients who underwent surgery for stage I-IIIA NSCLC were collected. Multivariate analyses identified tumor size, nodal status and nuclear, but not cytoplasmic, expression of survivin as significant independent predictors of OS, with a hazard ratio of 2.40 (95% CI 1.44, 3.99, p=0.001), 2.03 (95% CI 1.26, 3.26, p=0.003) and 1.83 (95% CI 1.01, 3.30, p=0.044), respectively. Median OS for nuclear survivin positive (score 1-2) and negative (score 0) patients were 23 months (95% CI 15, 31) and 36 months (95% CI 1, 76), respectively (p=0.01); five-year survival for score 1-2 and score 0 patients were 20% and 44.5%, respectively. Conversely, no significant impact on survival is found when patients are stratified according to cytoplasmic survivin expression., Conclusions: Data presented herein open the issue that prognosis of stage I-IIIA NSCLC can be linked to the cellular pattern of distribution of survivin.

To summarise the advances in the hormonal treatment of post-menopausal metastatic breast cancer, this paper reviews the published literature regarding the randomised trials comparing aromatase inhibitors (AIs) versus tamoxifen as a first-line therapeutic choice, or AIs versus megestrole acetate (MEG) as a second-line option. The pooled analysis of these authors on AI versus MEG as a second-line option for post-menopausal metastatic breast cancer suggested that AIs do not add any significant benefit over MEG in terms of overall response rate (ORR) and time to progression. According to the Cochrane Database, use of an AI as a second-line therapy versus any other endocrine therapy (mostly MEG) has shown a significant benefit in terms of overall survival, but not for progression-free survival, clinical benefit (CB) or ORR. Concerning the authors' comparisons between AIs versus tamoxifen as a first-line endocrine option in post-menopausal women with metastatic breast carcinoma, AIs seem to be superior to tamoxifen, with a significant benefit in terms of ORR, CB and time to progression being observed in favour of AIs over tamoxifen with fixed effects estimates. According to the Cochrane Database, there was an advantage to the use of AIs over tamoxifen in terms of progression-free survival and CB, but not for overall survival or ORR. With regards to toxicity, AIs show similar levels of hot flushes and arthralgia, increased risks of nausea, diarrhoea and vomiting, but a decreased risk of vaginal bleeding and thromboembolic events compared with other endocrine therapies. Weight gain, dyspnoea and peripheral oedema seem to be more frequent with MEG. At present, there is no proved overall survival difference in patients who are treated first with an AI and then with tamoxifen compared with the opposite sequence. In the metastatic setting, results are limited and are based on retrospective analyses.

Cisplatin must be considered the treatment standard for lung cancer chemotherapy, whatever the disease setting, at least in the Western world. After the seminal meta-analysis published in 1995, 12 randomized clinical trials (RCTs) exploring the benefits of adjuvant cisplatin-based chemotherapy have been completed, published, or presented. Although all these RCTs differ in patient features, two common suggestions emerge when the stage is taken into account: a significant benefit for chemotherapy is demonstrated for stage II and IIIA patients and none of these trials showed any significant benefit for adjuvant chemotherapy in stage IB patients. Ten years after this meta-analysis, a further individual patient data-pooled analysis exploring the eventual benefits of adjuvant cisplatin-based chemotherapy after surgery for early stage non-small cell lung cancer in the more recent RCTs has been presented. The 5-year overall survival benefit in favor of cisplatin-based chemotherapy was 5.3% (48.8% versus 43.3%, p = 0.004), with a relative risk reduction of 11%. These results confirm those reported by previous meta-analyses performed according to a literature-based approach. Advances are emerging in the selection of those patients who are likely to benefit more from such treatment. In this respect, the customized therapy based on molecular/genetic patient and disease features constitutes a new avenue to pursue.

Background: Customizing chemotherapy on the basis of chemosentitivity prediction may improve outcome in advanced bladder cancer patients. Since DNA damaging agents are the cornerstones of therapy, we hypothesized that levels of DNA repair genes could predict survival., Patients and Methods: Messenger RNA expression levels of excision repair cross complementing 1 (ERCC1), breast cancer 1 (BRCA1), ribonucleotide reductase subunit M1 (RRM1) and caveolin-1 were determined by RT-PCR in tumor DNA from 57 advanced and metastatic bladder cancer patients treated with either gemcitabine/cisplatin or gemcitabine/cisplatin/paclitaxel (Taxol). Levels were correlated with survival, time to disease progression and chemotherapy response., Results: Median survival was significantly higher in patients with low ERCC1 levels (25.4 versus 15.4 months; P = 0.03) (median follow-up 19 months). A trend towards longer time to progression was observed in patients with tumors expressing low levels of all markers. Levels of RRM1, BRCA1 and caveolin-1, however, failed to predict the survival and a clear link with chemotherapy response could not be established. On multivariate analysis with pretreatment prognostic factors, ERCC1 emerged as an independent predictive factor for survival., Conclusion: The results of the study indicate that ERCC1 may predict survival in bladder cancer treated by platinum-based therapy.

Background: Improving results in nonsmall-cell lung cancer (NSCLC) will require the development of new drugs and strategies to combine available agents. On the basis of data indicating the activity of docetaxel as second-line therapy, a Phase II study was conducted to evaluate the efficacy and toxicity of the sequential combination of chemotherapy consisting of cisplatin (P) and gemcitabine (G) followed by docetaxel (DOC) in patients with advanced NSCLC., Methods: Patients with 1997 TNM stage IIIB (pleural effusion)/stage IV NSCLC, performance status (PS) of 0-1, and normal organ function were eligible. Therapy consisted of P at 75 mg/m(2) on Day 1 and G 1200 mg/m(2) on Days 1 and 8 every 3 weeks for 3 cycles followed, in nonprogressive patients, by DOC 30 mg/m(2) every week for 6 consecutive weeks every 8 weeks for 2 cycles., Results: Fifty-two eligible patients were enrolled (M/F, 39/13; stage IIIB/IV, 8/44; PS 0, 73%, PS 1, 27%; median age, 58 years; range, 36-73). The overall response rate was 36.5% (95% confidence interval [CI]: 23-49). The median overall survival was 11 months (95% CI: 9-13); the median progression-free survival was 6 months (95% CI: 5-7); and the 1- and 2-year survivals were 48% and 25%, respectively. One- and 2-year progression-free survivals were 12% and 8%, respectively. Both phases of the treatment protocol were well tolerated., Conclusions: P/G followed by weekly DOC is well tolerated and active as first-line therapy for NSCLC patients and provides a feasible chemotherapeutic option in this clinical setting.

Purposes: To evaluate whether the incidence of recurrent venous thromboembolism (VTE) events after therapy differs for patients treated with long-term low-molecular-weight heparin (LMWH) or oral anticoagulant therapy (OAT)., Methods: All randomized studies were searched through computerized queries of MEDLINE, the Cochrane Controlled Trials Register, the American Society of Hematology abstract database, and the American Society of Clinical Oncology abstract database., Results: Eleven studies including 2,907 patients were identified. Seven studies evaluated a period of 3 to 9 months after cessation of the allocated treatment: 5.4% of patients in the LMWH group vs 4% in the arm allocated to OAT had an episode of recurrent symptomatic VTE. Combined analysis showed a nonsignificant trend in lowering recurrent symptomatic VTE in favor of OAT (relative risk [RR], 1.29; 95% confidence interval [CI], 0.82 to 2.02; p = 0.27). By contrast, during active treatment, a statistically significant reduction of the risk of recurrent symptomatic VTE in favor of LMWH over OAT was registered (RR, 0.63; 95% CI, 0.47 to 0.83; p = 0.001). Regarding cancer patients only, 37 of 569 patients (6.5%) in the LMWH group had recurrent symptomatic VTE vs 69 of 546 patients (12.6%) in the OAT group, with a statistically significant reduction of the risk of recurrent symptomatic VTE in favor of LMWH (RR, 0.52; 95% CI, 0.35 to 0.76; p = 0.001)., Conclusions: Despite the significant reduction of the risk of recurrent symptomatic VTE in favor of LMWH over OAT during treatment, patients treated with long-term LMWH do not seem to have more frequently recurrent VTE events compared with OAT after cessation of therapy. The significant difference favoring LMWH over OAT among all patients receiving treatment comes mostly from studies enrolling cancer patients.

The purpose of this study was to estimate in all randomised trials the relative risk of overall response rate (ORR), clinical benefit (CB), time to progression (TTP), overall survival (OS), and toxicity of aromatase inhibitors (AI), compared with tamoxifen (Tam) as first-line endocrine therapy in postmenopausal metastatic breast cancer (PMBC) women. Prospective randomised studies were searched through computerised queries of MEDLINE, EMBASE, and the American Society of Clinical Oncology (ASCO) abstract database. Relative risk, 95% confidence interval, and heterogeneity were derived according to the inverse variance and Mantel-Haenszel method and Q statistics. Six phase III prospective randomised trials including 2787 women were gathered. A significant advantage in ORR (P = 0.042), TTP (P = 0.007), and CB (P = 0.001) in favour of AI over Tam was detected at the fixed effects model. These results were not significant at the random effects model, owing to the significant heterogeneity. On the contrary, no difference was registered for OS (P = 0.743) with no significant heterogeneity. Regarding toxicity, Tam caused more frequently thromboembolic events (P = 0.005) and vaginal bleeding (P = 0.001) compared with AI. Aromatase inhibitors appear to be superior to Tam as first-line endocrine option in PMBC women. Owing to a component of variability between the six studies analysed, the random effects estimates differed from corresponding fixed ones. Investigators should assess heterogeneity of trial results before deriving summary estimates of treatment effect.
