Objectives: IMbrella A is a Phase III extension study that allowed rollover from Roche/Genentech-sponsored atezolizumab trials, including IMpower133, a Phase I/III trial of first-line atezolizumab or placebo plus carboplatin/etoposide in extensive-stage small cell lung cancer. We report outcomes from an exploratory analysis of IMpower133 with extended time-to-event data for patients who rolled over to IMbrella A., Materials and Methods: IMpower133 patients could roll over to IMbrella A to receive atezolizumab 1200 mg intravenously every three weeks if they continued to receive atezolizumab at IMpower133 closure or were in survival follow-up after atezolizumab discontinuation. Overall survival and safety were assessed; only serious adverse events and AEs of special interest were collected in IMbrella A., Results: Eighteen of 26 eligible patients rolled over to IMbrella A. At clinical cutoff (March 16, 2023), median follow-up in the atezolizumab plus carboplatin/etoposide arm (IMpower133 and IMbrella A) was 59.4 months. The three-, four-, and five-year overall survival (95 % CI) estimates were 16 % (11 %-21 %), 13 % (8 %-18 %), and 12 % (7 %-17 %), respectively. In IMbrella A, serious adverse events occurred in three patients (16.7 %), and one adverse event of special interest was reported (grade two hypothyroidism)., Conclusion: This long-term analysis of patients from IMbrella A previously enrolled in IMpower133 provides the first report of five-year overall survival outcomes in patients with extensive-stage small cell lung cancer treated with first-line cancer immunotherapy and chemotherapy. While limited by small patient numbers and lack of long-term data for the IMpower133 control arm, exploratory overall survival analyses in patients treated with atezolizumab plus carboplatin/etoposide compared favorably with historical data with chemotherapy alone.

Surgical resection of pulmonary adenocarcinoma is considered to be curative but progression-free survival (PFS) has remained highly variable. Antitumor immune response may be important, however, the prognostic significance of tumor-infiltrating natural killer (NK) and regulatory T (Treg) lymphocytes is uncertain. Resected pulmonary adenocarcinoma tissues (n = 115) were studied by immunohistochemical detection of NKp46 and FoxP3 positivity to identify NK and Treg cells, respectively. Association of cell densities with clinicopathological features and progression-free survival (PFS) as well as overall survival (OS) were analyzed with a follow-up time of 60 months. Both types of immune cells were accumulated predominantly in tumor stroma. NK cell density showed association with female gender, non-smoking and KRAS wild-type status. According to Kaplan-Meier analysis, PFS and OS proved to be longer in patients with high NK or Treg cell densities (p = 0.0293 and p = 0.0375 for PFS, p = 0.0310 and p = 0.0448 for OS, respectively). Evaluating the prognostic effect of the combination of NK and Treg cell density values revealed that PFS and OS were significantly longer in NK high /Treg high cases compared to the other groups combined (p = 0.0223 and p = 0.0325, respectively). Multivariate Cox regression analysis indicated that high NK cell density was independent predictor of longer PFS while high NK and high Treg cell densities both proved significant predictors of longer OS. The NK high /Treg high combination also proved to be an independent prognostic factor for both PFS and OS. In conclusion, NK and Treg cells can be components of the innate and adaptive immune response at action against progression of pulmonary adenocarcinoma., 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 © 2024 Elsevier B.V.

Purpose: In the CASPIAN trial, first-line durvalumab plus platinum-etoposide (EP) significantly improved overall survival (OS) versus EP alone in extensive-stage small cell lung cancer (ES-SCLC). We report exploratory analyses of CASPIAN outcomes by programmed cell death ligand-1 (PD-L1) expression and tissue tumor mutational burden (tTMB)., Experimental Design: Patients were randomized (1:1:1) to durvalumab (1,500 mg) plus EP, durvalumab plus tremelimumab (75 mg) plus EP, or EP alone. Treatment effects in PD-L1 and tTMB subgroups were estimated using an unstratified Cox proportional hazards model., Results: The PD-L1 and tTMB biomarker-evaluable populations (BEP) comprised 54.4% (438/805) and 35.2% (283/805) of the intention-to-treat population, respectively. PD-L1 prevalence was low: 5.7%, 25.8%, and 28.3% had PD-L1 expression on ≥1% tumor cells (TC), ≥1% immune cells (IC), and ≥1% TCs or ICs, respectively. OS benefit with durvalumab plus EP versus EP was similar across PD-L1 subgroups, with HRs all falling within the 95% confidence interval (CI) for the PD-L1 BEP (0.47‒0.79). OS benefit with durvalumab plus tremelimumab plus EP versus EP was greater in PD-L1 ≥1% versus <1% subgroups, although CIs overlapped. There was no evidence of an interaction between tTMB and treatment effect on OS (durvalumab plus EP vs. EP, P = 0.916; durvalumab plus tremelimumab plus EP vs. EP, P = 0.672)., Conclusions: OS benefit with first-line durvalumab plus EP in patients with ES-SCLC was observed regardless of PD-L1 or tTMB status. PD-L1 expression may prove to be a useful biomarker for combined treatment with PD-(L)1 and CTLA-4 inhibition, although this requires confirmation with an independent dataset.

Objectives: In the Phase I/III IMpower133 study, first-line atezolizumab plus carboplatin and etoposide (CP/ET) treatment for extensive-stage small cell lung cancer (ES-SCLC) significantly improved overall survival (OS) and progression-free survival versus placebo plus CP/ET. We explored patient and disease characteristics associated with long-term survival in IMpower133, and associations of differential gene expression and SCLC-A (ASCL1-driven), SCLC-N (NEUROD1-driven), SCLC-P (POU2F3-driven), and SCLC-inflamed (SCLC-I) transcriptional subtypes with long-term survival., Materials and Methods: Patients with previously untreated ES-SCLC were randomized 1:1 to four 21-day cycles of CP/ET with atezolizumab or placebo. Long-term survivors (LTS) were defined as patients who lived ≥ 18 months post randomization. A generalized linear model was used to evaluate the odds of living ≥ 18 months. Differential gene expression was analyzed using RNA-sequencing data in LTS and non-LTS. OS was assessed by T-effector and B-cell gene signature expression. Distribution of SCLC transcriptional subtypes was assessed in LTS and non-LTS., Results: More LTS were in the atezolizumab arm (34%) than in the placebo arm (20%). The odds ratio for living ≥ 18 months in the atezolizumab arm versus the placebo arm was 2.1 (P < 0.03). Enhanced immune-related signaling was seen in LTS in both arms. Exploratory OS analyses showed atezolizumab treatment benefit versus placebo across T-effector and B-cell gene signature expression subgroups. A higher proportion of LTS than non-LTS in both arms had the SCLC-I subtype; this difference was particularly pronounced in the atezolizumab arm., Conclusion: These exploratory analyses suggest that long-term survival is more likely with atezolizumab than placebo in ES-SCLC, confirming the treatment benefit of the IMpower133 regimen., Clinicaltrial: gov Identifier: NCT02763579., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: S.V.L. declares grants or contracts from Alkermes, Bayer, Blueprint, Bristol Myers Squibb, Elevation Oncology, Genentech, Lilly, Merck, Merus, Pfizer, Rain Therapeutics, RAPT, Turning Point Therapeutics; consulting fees from Amgen, AstraZeneca, Bayer, BeiGene, Blueprint, Bristol Myers Squibb, Daiichi Sankyo, Eisai, Elevation Oncology, Genentech/Roche, Gilead, Guardant Health, Janssen, Jazz Pharmaceuticals, Lilly, Merck/Merck Sharpe & Dohme, Novartis, Regeneron, Sanofi, Takeda, Turning Point Therapeutics; and participation on a Data Safety Monitoring or Advisory Board for Candel Therapeutics.

Introduction: In the phase 1/3 IMpower133 study, atezolizumab plus carboplatin and etoposide (CP/ET) followed by maintenance atezolizumab for first-line treatment of extensive-stage SCLC (ES-SCLC) led to improvement in both overall survival (OS) and progression-free survival (PFS) versus placebo plus CP/ET followed by maintenance placebo. We explored the benefit of atezolizumab versus placebo in the subset of patients who reached the IMpower133 maintenance phase and the safety profile of maintenance therapy., Methods: Patients with untreated ES-SCLC were randomized 1:1 to four 21-day cycles of CP/ET with atezolizumab or placebo, followed by maintenance atezolizumab or placebo. The primary end points were OS and investigator-assessed PFS. A multivariate Cox model from the start of maintenance treatment was used to evaluate the treatment effect and account for lead-time bias; a generalized linear model was used to identify prognostic or predictive characteristics for reaching the maintenance phase., Results: A similar proportion of patients in each arm received at least the first dose of maintenance therapy (atezolizumab: 77%, n = 154 of 201; placebo: 81%, n = 164 of 202) and were included in the maintenance analysis population. An Eastern Cooperative Oncology Group performance status of 0 and absence of liver metastases at baseline were identified as prognostic factors for reaching the maintenance phase. The positive treatment effect with atezolizumab remained after adjusting for baseline characteristics. Median OS and PFS from the start of maintenance therapy in the atezolizumab versus placebo arm were 12.5 versus 8.4 months (hazard ratio = 0.59, 95% confidence interval: 0.43-0.80) and 2.6 versus 1.8 months (hazard ratio = 0.63 [95% confidence interval: 0.49-0.80]), respectively. Treatment-related adverse events from the start of maintenance therapy occurred in 41% (n = 64 of 155) and 25% (n = 41 of 163) of safety-evaluable patients in the atezolizumab and placebo arms, respectively, and were grade 3 or 4 in 28% (n = 43 of 155) and 23% (n = 37 of 163) of the respective populations; no patient in the atezolizumab arm and one patient in the placebo arm had a grade 5 treatment-related adverse event., Conclusions: These data in the context of other immunotherapy trials in ES-SCLC suggest that induction with atezolizumab plus CP/ET and maintenance treatment with atezolizumab are important components that contributed to the OS benefit observed in IMpower133. Safety results from randomization and from the start of maintenance therapy were similar between the treatment arms despite the continuation of atezolizumab in the maintenance phase., (Copyright © 2022.

Background: In the phase III CASPIAN study, first-line durvalumab in combination with etoposide plus either cisplatin or carboplatin (EP) significantly improved overall survival (OS) versus EP alone in extensive-stage small-cell lung cancer (ES-SCLC). Durvalumab plus tremelimumab plus EP numerically improved OS versus EP, but did not reach statistical significance. Here we report updated OS in censored patients after median follow-up of >3 years., Patients and Methods: 805 patients with treatment-naïve ES-SCLC were randomized 1 : 1 : 1 to durvalumab plus EP, durvalumab plus tremelimumab plus EP, or EP. The two primary endpoints were OS for durvalumab plus EP versus EP and for durvalumab plus tremelimumab plus EP versus EP., Results: As of 22 March 2021 (median follow-up 39.4 months, 86% maturity), durvalumab plus EP continued to demonstrate improved OS versus EP: hazard ratio (HR) 0.71 [95% confidence interval (CI) 0.60-0.86; nominal P = 0.0003]; median OS was 12.9 versus 10.5 months, and 36-month OS rate was 17.6% versus 5.8%. Durvalumab plus tremelimumab plus EP continued to numerically improve OS versus EP: HR 0.81 (95% CI: 0.67-0.97; nominal P = 0.0200); median OS was 10.4 months, and 36-month OS rate was 15.3%. Twenty-seven and nineteen patients in the durvalumab plus EP and durvalumab plus tremelimumab plus EP arms, respectively, remained on durvalumab treatment at data cut-off., Conclusions: Three times more patients were estimated to be alive at 3 years when treated with durvalumab plus EP versus EP, with the majority still receiving durvalumab at data cut-off, further establishing durvalumab plus EP as first-line standard of care for ES-SCLC., Competing Interests: Disclosure LPA reports receiving grants from AstraZeneca, Bristol-Myers Squibb, MSD, and Pfizer; consulting fees from Amgen, AstraZeneca, Bayer, Blueprint Medicines, Bristol-Myers Squibb, Ipsen, Lilly, Merck, Mirati, MSD, Novartis, Pfizer, PharmaMar, Roche, Sanofi, and Servier; and honoraria from AstraZeneca, Janssen, Merck, Mirati, and Sanofi, and reports a leadership role with Genomica and Altum Sequencing, all outside the submitted work.

Background: First-line durvalumab plus etoposide with either cisplatin or carboplatin (platinum-etoposide) showed a significant improvement in overall survival versus platinum-etoposide alone in patients with extensive-stage small-cell lung cancer (ES-SCLC) in the CASPIAN study. Here we report updated results, including the primary analysis for overall survival with durvalumab plus tremelimumab plus platinum-etoposide versus platinum-etoposide alone., Methods: CASPIAN is an ongoing, open-label, sponsor-blind, randomised, controlled phase 3 trial at 209 cancer treatment centres in 23 countries worldwide. Eligible patients were aged 18 years or older (20 years in Japan) and had treatment-naive, histologically or cytologically documented ES-SCLC, with a WHO performance status of 0 or 1. Patients were randomly assigned (1:1:1) in blocks of six, stratified by planned platinum, using an interactive voice-response or web-response system to receive intravenous durvalumab plus tremelimumab plus platinum-etoposide, durvalumab plus platinum-etoposide, or platinum-etoposide alone. In all groups, patients received etoposide 80-100 mg/m 2 on days 1-3 of each cycle with investigator's choice of either carboplatin area under the curve 5-6 mg/mL/min or cisplatin 75-80 mg/m 2 on day 1 of each cycle. Patients in the platinum-etoposide group received up to six cycles of platinum-etoposide every 3 weeks and optional prophylactic cranial irradiation (investigator's discretion). Patients in the immunotherapy groups received four cycles of platinum-etoposide plus durvalumab 1500 mg with or without tremelimumab 75 mg every 3 weeks followed by maintenance durvalumab 1500 mg every 4 weeks. The two primary endpoints were overall survival for durvalumab plus platinum-etoposide versus platinum-etoposide and for durvalumab plus tremelimumab plus platinum-etoposide versus platinum-etoposide in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered at ClinicalTrials.gov, NCT03043872., Findings: Between March 27, 2017, and May 29, 2018, 972 patients were screened and 805 were randomly assigned (268 to durvalumab plus tremelimumab plus platinum-etoposide, 268 to durvalumab plus platinum-etoposide, and 269 to platinum-etoposide). As of Jan 27, 2020, the median follow-up was 25·1 months (IQR 22·3-27·9). Durvalumab plus tremelimumab plus platinum-etoposide was not associated with a significant improvement in overall survival versus platinum-etoposide (hazard ratio [HR] 0·82 [95% CI 0·68-1·00]; p=0·045); median overall survival was 10·4 months (95% CI 9·6-12·0) versus 10·5 months (9·3-11·2). Durvalumab plus platinum-etoposide showed sustained improvement in overall survival versus platinum-etoposide (HR 0·75 [95% CI 0·62-0·91]; nominal p=0·0032); median overall survival was 12·9 months (95% CI 11·3-14·7) versus 10·5 months (9·3-11·2). The most common any-cause grade 3 or worse adverse events were neutropenia (85 [32%] of 266 patients in the durvalumab plus tremelimumab plus platinum-etoposide group, 64 [24%] of 265 patients in the durvalumab plus platinum-etoposide group, and 88 [33%] of 266 patients in the platinum-etoposide group) and anaemia (34 [13%], 24 [9%], and 48 [18%]). Any-cause serious adverse events were reported in 121 (45%) patients in the durvalumab plus tremelimumab plus platinum-etoposide group, 85 (32%) in the durvalumab plus platinum-etoposide group, and 97 (36%) in the platinum-etoposide group. Treatment-related deaths occurred in 12 (5%) patients in the durvalumab plus tremelimumab plus platinum-etoposide group (death, febrile neutropenia, and pulmonary embolism [n=2 each]; enterocolitis, general physical health deterioration and multiple organ dysfunction syndrome, pneumonia, pneumonitis and hepatitis, respiratory failure, and sudden death [n=1 each]), six (2%) patients in the durvalumab plus platinum-etoposide group (cardiac arrest, dehydration, hepatotoxicity, interstitial lung disease, pancytopenia, and sepsis [n=1 each]), and two (1%) in the platinum-etoposide group (pancytopenia and thrombocytopenia [n=1 each])., Interpretation: First-line durvalumab plus platinum-etoposide showed sustained overall survival improvement versus platinum-etoposide but the addition of tremelimumab to durvalumab plus platinum-etoposide did not significantly improve outcomes versus platinum-etoposide. These results support the use of durvalumab plus platinum-etoposide as a new standard of care for the first-line treatment of ES-SCLC., Funding: AstraZeneca., (Copyright © 2021 Elsevier Ltd.

Objectives: In the phase III CASPIAN study, first-line durvalumab plus etoposide in combination with either cisplatin or carboplatin (EP) significantly improved overall survival (primary endpoint) versus EP alone in patients with extensive-stage small-cell lung cancer (ES-SCLC) at the interim analysis. Here we report patient-reported outcomes (PROs)., Materials and Methods: Treatment-naïve patients with ES-SCLC received 4 cycles of durvalumab plus EP every 3 weeks followed by maintenance durvalumab every 4 weeks until progression, or up to 6 cycles of EP every 3 weeks. PROs, assessed with the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) version 3 and its lung cancer module, the Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13), were prespecified secondary endpoints. Changes from baseline to disease progression or 12 months in prespecified key disease-related symptoms (cough, dyspnea, chest pain, fatigue, appetite loss) were analyzed with a mixed model for repeated measures. Time to deterioration (TTD) of symptoms, functioning, and global health status/quality of life (QoL) from randomization was analyzed., Results: In the durvalumab plus EP and EP arms, 261 and 260 patients were PRO-evaluable. Patients in both arms experienced numerically reduced symptom burden over 12 months or until progression for key symptoms. For the improvements from baseline in appetite loss, the between-arm difference was statistically significant, favoring durvalumab plus EP (difference, -4.5; 99% CI: -9.04, -0.04; nominal p = 0.009). Patients experienced longer TTD with durvalumab plus EP versus EP for all symptoms (hazard ratio [95% CI] for key symptoms: cough 0.78 [0.600‒1.026]; dyspnea 0.79 [0.625‒1.006]; chest pain 0.76 [0.575‒0.996]; fatigue 0.82 [0.653‒1.027]; appetite loss 0.70 [0.542‒0.899]), functioning, and global health status/QoL., Conclusion: Addition of durvalumab to first-line EP maintained QoL and delayed worsening of patient-reported symptoms, functioning, and global health status/QoL compared with EP., (Copyright © 2020 The Authors.

Chronic obstructive pulmonary disease (COPD) is a common comorbidity of non-small cell lung cancer (NSCLC). COPD is characterized by systemic inflammation and lymphocyte dysfunction, mechanisms that are also known to accelerate progression of advanced (IIIB-IV) stage NSCLC. We aimed to find out whether COPD exerts an influence on tumor induced inflammatory and lymphoid responses and progression-free survival (PFS) after first-line treatment in advanced NSCLC. Patients suffering from NSCLC (n = 95), COPD (n = 54), NSCLC+COPD (n = 80) and healthy controls (n = 60) were included. PFS, neutrophil granulocyte and lymphocyte cell counts were recorded. Serum IFNγ, TNFα, VEGF concentrations were measured by using multiplex cytometric bead-based immunoassay. Prevalence of myeloid-derived suppressor cell populations (MDSC-s), and signs of T cell exhaustion were tested by using flow cytometry. Median PFS increased in the NSCLC+COPD group compared to NSCLC patients without COPD (7.4 vs 4.9 months, p < 0.01). NSCLC+COPD patients had 1.7 times (1.2-2.4) more likely to have longer PFS compared to NSCLC patients without COPD (Cox analysis, p < 0.01). Neutrophil cell counts, CRP, IFNγ and TNFα concentrations were all reduced in NSCLC+COPD (all p < 0.05 vs NSCLC). NSCLC+COPD was also associated with reduced serum IL-10 concentration and increased granzyme-B positive CD8 cell counts compared to NSCLC without COPD. The effects of VEGF and MDSC-s on systemic inflammation appeared to be blunted by COPD in patients suffering from advanced NSCLC. Concomitant COPD moderates tumor-induced inflammation and supports some effector lymphoid functions and thereby may be an independent positive predictive factor of longer PFS after first-line therapy in advanced NSCLC.

Background: Most patients with small-cell lung cancer (SCLC) have extensive-stage disease at presentation, and prognosis remains poor. Recently, immunotherapy has demonstrated clinical activity in extensive-stage SCLC (ES-SCLC). The CASPIAN trial assessed durvalumab, with or without tremelimumab, in combination with etoposide plus either cisplatin or carboplatin (platinum-etoposide) in treatment-naive patients with ES-SCLC., Methods: This randomised, open-label, phase 3 trial was done at 209 sites across 23 countries. Eligible patients were adults with untreated ES-SCLC, with WHO performance status 0 or 1 and measurable disease as per Response Evaluation Criteria in Solid Tumors, version 1.1. Patients were randomly assigned (in a 1:1:1 ratio) to durvalumab plus platinum-etoposide; durvalumab plus tremelimumab plus platinum-etoposide; or platinum-etoposide alone. All drugs were administered intravenously. Platinum-etoposide consisted of etoposide 80-100 mg/m 2 on days 1-3 of each cycle with investigator's choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m 2 (administered on day 1 of each cycle). Patients received up to four cycles of platinum-etoposide plus durvalumab 1500 mg with or without tremelimumab 75 mg every 3 weeks followed by maintenance durvalumab 1500 mg every 4 weeks in the immunotherapy groups and up to six cycles of platinum-etoposide every 3 weeks plus prophylactic cranial irradiation (investigator's discretion) in the platinum-etoposide group. The primary endpoint was overall survival in the intention-to-treat population. We report results for the durvalumab plus platinum-etoposide group versus the platinum-etoposide group from a planned interim analysis. Safety was assessed in all patients who received at least one dose of their assigned study treatment. This study is registered at ClinicalTrials.gov, NCT03043872, and is ongoing., Findings: Patients were enrolled between March 27, 2017, and May 29, 2018. 268 patients were allocated to the durvalumab plus platinum-etoposide group and 269 to the platinum-etoposide group. Durvalumab plus platinum-etoposide was associated with a significant improvement in overall survival, with a hazard ratio of 0·73 (95% CI 0·59-0·91; p=0·0047]); median overall survival was 13·0 months (95% CI 11·5-14·8) in the durvalumab plus platinum-etoposide group versus 10·3 months (9·3-11·2) in the platinum-etoposide group, with 34% (26·9-41·0) versus 25% (18·4-31·6) of patients alive at 18 months. Any-cause adverse events of grade 3 or 4 occurred in 163 (62%) of 265 treated patients in the durvalumab plus platinum-etoposide group and 166 (62%) of 266 in the platinum-etoposide group; adverse events leading to death occurred in 13 (5%) and 15 (6%) patients., Interpretation: First-line durvalumab plus platinum-etoposide significantly improved overall survival in patients with ES-SCLC versus a clinically relevant control group. Safety findings were consistent with the known safety profiles of all drugs received., Funding: AstraZeneca., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background: Enhancing tumor-specific T-cell immunity by inhibiting programmed death ligand 1 (PD-L1)-programmed death 1 (PD-1) signaling has shown promise in the treatment of extensive-stage small-cell lung cancer. Combining checkpoint inhibition with cytotoxic chemotherapy may have a synergistic effect and improve efficacy., Methods: We conducted this double-blind, placebo-controlled, phase 3 trial to evaluate atezolizumab plus carboplatin and etoposide in patients with extensive-stage small-cell lung cancer who had not previously received treatment. Patients were randomly assigned in a 1:1 ratio to receive carboplatin and etoposide with either atezolizumab or placebo for four 21-day cycles (induction phase), followed by a maintenance phase during which they received either atezolizumab or placebo (according to the previous random assignment) until they had unacceptable toxic effects, disease progression according to Response Evaluation Criteria in Solid Tumors, version 1.1, or no additional clinical benefit. The two primary end points were investigator-assessed progression-free survival and overall survival in the intention-to-treat population., Results: A total of 201 patients were randomly assigned to the atezolizumab group, and 202 patients to the placebo group. At a median follow-up of 13.9 months, the median overall survival was 12.3 months in the atezolizumab group and 10.3 months in the placebo group (hazard ratio for death, 0.70; 95% confidence interval [CI], 0.54 to 0.91; P=0.007). The median progression-free survival was 5.2 months and 4.3 months, respectively (hazard ratio for disease progression or death, 0.77; 95% CI, 0.62 to 0.96; P=0.02). The safety profile of atezolizumab plus carboplatin and etoposide was consistent with the previously reported safety profile of the individual agents, with no new findings observed., Conclusions: The addition of atezolizumab to chemotherapy in the first-line treatment of extensive-stage small-cell lung cancer resulted in significantly longer overall survival and progression-free survival than chemotherapy alone.

Background: Bavituximab is a monoclonal antibody that targets phosphatidylserine in the presence of β2 glycoprotein 1 (β2GP1) to exert an antitumor immune response. This phase III trial determined the efficacy of bavituximab combined with docetaxel in patients with previously treated advanced non-small-cell lung cancer (NSCLC)., Patients and Methods: Key eligibility criteria included advanced non-squamous NSCLC with disease progression after treatment with platinum-based doublet chemotherapy, evidence of disease control after at least two cycles of first-line therapy, presence of measurable disease, ECOG performance status 0 or 1, adequate bone marrow and organ function, and no recent history of clinically significant bleeding. Eligible patients were randomized 1 : 1 to receive up to six 21-day cycles of docetaxel plus either weekly bavituximab 3 mg/kg or placebo until progression or toxicity. The primary end point was overall survival (OS)., Results: A total of 597 patients were enrolled. Median OS was 10.5 months in the docetaxel + bavituximab arm and was 10.9 months in the docetaxel + placebo arm (HR 1.06; 95% CI 0.88-1.29; P = 0.533). There was no difference in progression-free survival (HR 1.00; 95% CI 0.82-1.22; P = 0.990). Toxicities were manageable and similar between arms. In subset analysis, among patients with high baseline serum β2GP1 levels ≥200 µg/ml, a nonsignificant OS trend favored the bavituximab arm (HR 0.82; 95% CI 0.63-1.06; P = 0.134). Among patients who received post-study immune checkpoint inhibitor therapy, OS favored the bavituximab arm (HR 0.46; 95% CI 0.26-0.81; P = 0.006)., Conclusions: The combination of bavituximab plus docetaxel is not superior to docetaxel in patients with previously treated advanced NSCLC. The addition of bavituximab to docetaxel does not meaningfully increase toxicity. The potential benefit of bavituximab observed in patients with high β2GP1 levels and in patients subsequently treated with immune checkpoint inhibitors requires further investigation., Clinical Trial Number: NCT01999673.

Lessons Learned: The lack of efficacy associated with anti-EGFL7 combined with standard bevacizumab and chemotherapy in this phase II trial in non-small cell lung carcinoma is consistent with the lack of benefit observed in colorectal carcinoma, highlighting the challenge of enhancing the efficacy of VEGF inhibition in unselected populations.Future efforts with agents like anti-EGFL7 should be guided by advances in pharmacodynamic and predictive biomarker development for antiangiogenic agents., Background: Epidermal growth factor-like domain 7 (EGFL7) is an extracellular matrix-associated protein that is upregulated during angiogenesis and supports endothelial cell survival. This phase II trial evaluated the efficacy of the anti-EGFL7 antibody, parsatuzumab, in combination with bevacizumab plus platinum-based therapy for advanced or recurrent nonsquamous non-small cell lung cancer (NS-NSCLC)., Methods: Patients ( n  = 104) were randomized to either placebo or parsatuzumab (600 mg) in combination with bevacizumab (15 mg/kg) and carboplatin/paclitaxel, administered on day 1 of each 21-day cycle. Carboplatin and paclitaxel were administered for up to six cycles. Bevacizumab and parsatuzumab/placebo were administered for a maximum of 24 months., Results: The progression-free survival (PFS) hazard ratio (HR) was 1.7 (95% confidence interval [CI], 1.0-2.8; p  = .047). The median PFS was 6.7 months for the parsatuzumab arm versus 8.1 months for the placebo arm. The hazard ratio for overall survival (OS) was 1.1 (95% CI, 0.5-2.2; p  = .847). The objective response rate (ORR) was 29% in the parsatuzumab arm and 56% in the placebo arm. Overall safety and tolerability were consistent with the established toxicity profile of bevacizumab., Conclusion: There was no evidence of efficacy for the addition of parsatuzumab to the combination of bevacizumab and chemotherapy for first-line NS-NSCLC., (©AlphaMed Press; the data published online to support this summary is the property of the authors.)

Introduction: Necitumumab, a second-generation, recombinant human immunoglobulin G1 epidermal growth factor receptor antibody in the phase 3 SQUIRE trial (NCT00981058), increased survival benefit for patients randomized to receive necitumumab plus gemcitabine-cisplatin compared with those who received gemcitabine-cisplatin. Here we characterize health-related quality of life (HRQoL) and tolerability results., Methods: A total of 1093 patients with stage IV squamous non-small cell lung cancer were randomized 1:1 to receive necitumumab (800 mg absolute dose intravenously [IV]) plus gemcitabine-cisplatin (gemcitabine = 1250 mg/m(2) IV on days 1 and 8; cisplatin = 75 mg/m(2) IV on day 1) or gemcitabine-cisplatin alone (every 21 days) for up to six cycles. Patients receiving necitumumab plus gemcitabine-cisplatin without disease progression continued necitumumab until progression. HRQoL was measured by Eastern Cooperative Oncology Group performance status, the Lung Cancer Symptom Scale (LCSS), and the European Quality of Life Five-Dimensions questionnaire. Efficacy and LCSS outcomes were analyzed using the baseline maximum severity score of the LCSS. Tolerability was measured in terms of exposure to the study treatment and adverse events. Hospitalization rates were collected., Results: Most patients in both study arms similarly maintained Eastern Cooperative Oncology Group performance status and comparable LCSS and European Quality of Life Five-Dimensions questionnaire assessments. Patients with a higher baseline LCSS had a greater survival benefit on the necitumumab arm. Chemotherapy exposure was similar in both treatment arms; 51% of patients on the necitumumab plus gemcitabine-cisplatin arm continued on single-agent necitumumab. The most frequent grade 4 adverse events were neutropenia (6.1% versus 7.9%) and thrombocytopenia (3.2% versus 4.3%) in the necitumumab plus gemcitabine-cisplatin versus gemcitabine-cisplatin arms, respectively. Hospitalizations were slightly higher with necitumumab plus gemcitabine-cisplatin (36.4%) than with gemcitabine-cisplatin (34.0%)., Conclusions: The addition of necitumumab to gemcitabine-cisplatin was well tolerated, did not negatively affect HRQoL or toxicity, and particularly benefited patients with more severe baseline symptoms or lower HRQoL., (Copyright © 2016 International Association for the Study of Lung Cancer.

Background: MUC1 is a tumour-associated antigen expressed by many solid tumours, including non-small-cell lung cancer. TG4010 is a modified vaccinia Ankara expressing MUC1 and interleukin 2. In a previous study, TG4010 combined with chemotherapy showed activity in non-small-cell lung cancer and the baseline value of CD16, CD56, CD69 triple-positive activated lymphocytes (TrPAL) was shown to be potentially predictive of TG4010 efficacy. In this phase 2b part of the phase 2b/3 TIME trial, we further assess TG4010 in combination with first-line chemotherapy and use of the TrPAL biomarker in this setting., Methods: In this phase 2b part of a randomised, double-blind, placebo-controlled, phase 2b/3 trial, we recruited previously untreated patients aged 18 years or older with stage IV non-small-cell lung cancer without a known activating EGFR mutation and with MUC1 expression in at least 50% of tumoural cells. Patients were randomly allocated (1:1) by an external service provider to subcutaneous injections of 10(8) plaque-forming units of TG4010 or placebo from the beginning of chemotherapy every week for 6 weeks and then every 3 weeks up to progression, discontinuation for any reason, or toxic effects, stratified according to baseline value of TrPAL (≤ or > the upper limit of normal [ULN]) and, in addition, a dynamic minimisation procedure was used, taking into account chemotherapy regimen, histology, addition or not of bevacizumab, performance status, and centre. Patients, site staff, monitors, the study funder, data managers, and the statistician were masked to treatment identity. The primary endpoint was progression-free survival, assessed every 6 weeks, to validate the predictive value of the TrPAL biomarker. If patients with TrPAL values of less than or equal to the ULN had a Bayesian probability of more than 95% that the true hazard ratio (HR) for progression-free survival was less than 1, and if those with TrPAL values of greater than the ULN had a probability of more than 80% that the true HR for progression-free survival was more than 1, the TrPAL biomarker would be validated. We did primary analyses in the intention-to-treat population and safety analyses in those who had received at least one dose of study drug and had at least one valid post-baseline safety assessment. Monitors, site staff, and patients are still masked to treatment assignment. This trial is registered with ClinicalTrials.gov, number NCT01383148., Findings: Between April 10, 2012, and Sept 12, 2014, we randomly allocated 222 patients (TG4010 and chemotherapy 111 [50%]; placebo and chemotherapy 111 [50%]). In the whole population, median progression-free survival was 5·9 months (95% CI 5·4-6·7) in the TG4010 group and 5·1 months (4·2-5·9) in the placebo group (HR 0·74 [95% CI 0·55-0·98]; one-sided p=0·019). In patients with TrPAL values of less than or equal to the ULN, the HR for progression-free survival was 0·75 (0·54-1·03); the posterior probability of the HR being less than 1 was 98·4%, and thus the primary endpoint was met. In patients with TrPAL values of greater than the ULN, the HR for progression-free survival was 0·77 (0·42-1·40); the posterior probability of the HR being greater than 1 was 31·3%, and the primary endpoint was not met. We noted grade 1-2 injection-site reactions in 36 (33%) of 110 patients in the TG4010 group versus four (4%) of 107 patients in the placebo group. We noted no grade 3 or 4 nor serious adverse events deemed to be related to TG4010 only. Four (4%) patients presented grade 3 or 4 adverse events related to TG4010 and other study treatments (chemotherapy or bevacizumab) versus 11 (10%) in the placebo group. No serious adverse event was related to the combination of TG4010 with other study treatments. The most frequent severe adverse events were neutropenia (grade 3 29 [26%], grade 4 13 [12%] in the TG4010 group vs grade 3 22 [21%], grade 4 11 [10%] in the placebo group), anaemia (grade 3 12 [11%] vs grade 3 16 [15%]), and fatigue (grade 3 12 [11%], grade 5 one [1%] vs grade 3 13 [12%]; no grade 4 events)., Interpretation: TG4010 plus chemotherapy seems to improve progression-free survival relative to placebo plus chemotherapy. These data support the clinical value of the TrPAL biomarker in this clinical setting; because the primary endpoint was met, the trial is to continue into the phase 3 part., Funding: Transgene, Avancées Diagnostiques pour de Nouvelles Approches Thérapeutiques (ADNA), and OSEO., (Copyright © 2016 Elsevier Ltd.

Purpose: Lung cancer may be associated with airway acidification due to enhanced airway inflammation and oxidative stress. Exhaled breath condensate (EBC) pH is a non-invasive indicator of airway acidity; however, it is still unclear how EBC pH changes in lung cancer. The aim of the study was to investigate EBC pH in lung cancer together with clinical variables., Methods: Thirty-five patients with lung cancer and 37 control subjects (21 patients with stable COPD and 16 non-COPD smokers) were enrolled. EBC was collected for pH, which was determined with the argon-purging method, compared among the groups and correlated with clinical variables of patients with lung cancer., Results: No difference was found in EBC pH between patients with lung cancer and control subjects. However, endobronchial tumour localisation, squamous-cell carcinoma subtype and gastro-oesophageal reflux were associated with low EBC pH values. No relationship was observed between EBC pH and the presence of COPD, lung function variables or smoking history., Conclusions: Although, EBC pH is unchanged in lung cancer, lower EBC pH values are associated with distinct phenotypes. Our findings could facilitate further research on airway acidity in lung cancer.

Background: Necitumumab is a second-generation, recombinant, human immunoglobulin G1 EGFR antibody. In this study, we aimed to compare treatment with necitumumab plus gemcitabine and cisplatin versus gemcitabine and cisplatin alone in patients with previously untreated stage IV squamous non-small-cell lung cancer., Methods: We did this open-label, randomised phase 3 study at 184 investigative sites in 26 countries. Patients aged 18 years or older with histologically or cytologically confirmed stage IV squamous non-small-cell lung cancer, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and adequate organ function and who had not received previous chemotherapy for their disease were eligible for inclusion. Enrolled patients were randomly assigned centrally 1:1 to a maximum of six 3-week cycles of gemcitabine and cisplastin chemotherapy with or without necitumumab according to a block randomisation scheme (block size of four) by a telephone-based interactive voice response system or interactive web response system. Chemotherapy was gemcitabine 1250 mg/m(2) administered intravenously over 30 min on days 1 and 8 of a 3-week cycle and cisplatin 75 mg/m(2) administered intravenously over 120 min on day 1 of a 3-week cycle. Necitumumab 800 mg, administered intravenously over a minimum of 50 min on days 1 and 8, was continued after the end of chemotherapy until disease progression or intolerable toxic side-effects occurred. Randomisation was stratified by ECOG performance status and geographical region. Neither physicians nor patients were masked to group assignment because of the expected occurrence of acne-like rash--a class effect of EGFR antibodies--that would have unmasked most patients and investigators to treatment. The primary endpoint was overall survival, analysed by intention to treat. We report the final clinical analysis. This study is registered with ClinicalTrials.gov, number NCT00981058., Findings: Between Jan 7, 2010, and Feb 22, 2012, we enrolled 1093 patients and randomly assigned them to receive necitumumab plus gemcitabine and cisplatin (n=545) or gemcitabine and cisplatin (n=548). Overall survival was significantly longer in the necitumumab plus gemcitabine and cisplatin group than in the gemcitabine and cisplatin alone group (median 11·5 months [95% CI 10·4-12·6]) vs 9·9 months [8·9-11·1]; stratified hazard ratio 0·84 [95% CI 0·74-0·96; p=0·01]). In the necitumumab plus gemcitabine and cisplatin group, the number of patients with at least one grade 3 or worse adverse event was higher (388 [72%] of 538 patients) than in the gemcitabine and cisplatin group (333 [62%] of 541), as was the incidence of serious adverse events (257 [48%] of 538 patients vs 203 [38%] of 541). More patients in the necitumumab plus gemcitabine and cisplatin group had grade 3-4 hypomagnesaemia (47 [9%] of 538 patients in the necitumumab plus gemcitabine and cisplatin group vs six [1%] of 541 in the gemcitabine and cisplatin group) and grade 3 rash (20 [4%] vs one [<1%]). Including events related to disease progression, adverse events with an outcome of death were reported for 66 (12%) of 538 patients in the necitumumab plus gemcitabine and cisplatin group and 57 (11%) of 541 patients in the gemcitabine and cisplatin group; these were deemed to be related to study drugs in 15 (3%) and ten (2%) patients, respectively. Overall, we found that the safety profile of necitumumab plus gemcitabine and cisplatin was acceptable and in line with expectations., Interpretation: Our findings show that the addition of necitumumab to gemcitabine and cisplatin chemotherapy improves overall survival in patients with advanced squamous non-small-cell lung cancer and represents a new first-line treatment option for this disease., Funding: Eli Lilly and Company., (Copyright © 2015 Elsevier Ltd.

We have already demonstrated in a small cohort of 17 non-small cell lung cancer patients that ERCC1 (excision repair cross-complementation group 1) protein expression decreased after platinum-based treatment, however, certain clinicopathological parameters, such as histologic subtypes, ERCC1 expression scores, chemotherapeutic combinations, response rate, gender and smoking history were not analyzed. The aim of our present study was to extend the studied cohort and analyze those parameters. ERCC1 protein expression was examined in 46 patients treated with neoadjuvant chemotherapy. 46 bronchoscopic biopsy samples (27 squamous cell carcinomas /SCC/ and 19 adenocarcinomas /ADC/) together with their corresponding surgical biopsies were studied. ERCC1 immunohistochemistry was performed on formalin-fixed, paraffin-embedded tissues. Staining scores were calculated by multiplying the percentage of positive tumor cells (0-100) by the staining intensity (0-3). 24/27 bronchoscopic SCC tissues expressed ERCC1. Thirteen of these cases became negative after neoadjuvant therapy and the expression differences between pre- and postchemotherapy samples were highly significant (p < 0.001). 11/19 bronchoscopic ADC tissues expressed ERCC1. Six of these cases became negative after neoadjuvant therapy and the expression differences were significant (p < 0.010). There was no newly expressed ERCC1 postoperatively. Comparison of staining score changes revealed more pronounced decrease in SCC (p = 0.032). We observed no correlation between initial ERCC1 level or ERCC1 decrease and overall survival, but we demonstrated correlations between decrease in ERCC1 expression and histologic subtypes of tumors and gender. We could confirm our previous data in a larger cohort that platinum-based chemotherapy affects the ERCC1 expression probably referring to an induction of tumor cell selection.

Background: Necitumumab is a second-generation recombinant human immunoglobulin G1 EGFR monoclonal antibody that competitively inhibits ligand binding. We aimed to compare necitumumab plus pemetrexed and cisplatin with pemetrexed and cisplatin alone in patients with previously untreated, stage IV, non-squamous non-small-cell lung cancer (NSCLC)., Methods: We did this randomised, open-label, controlled phase 3 study at 103 sites in 20 countries. Patients aged 18 years or older, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and adequate organ function, were randomly assigned 1:1 to treatment with a block randomisation scheme (block size of four) via a telephone-based interactive voice-response system or interactive web-response system. Patients received either cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2) on day 1 of a 3-week cycle for a maximum of six cycles alone, or with necitumumab 800 mg on days 1 and 8. Necitumumab was continued after the end of chemotherapy until disease progression or unacceptable toxic effects. Randomisation was stratified by smoking history, ECOG performance status, disease histology, and geographical region. Patients and study investigators were not masked to group assignment. The primary endpoint was overall survival. Efficacy analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00982111., Findings: Between Nov 11, 2009, and Feb 2, 2011, we randomly assigned 633 patients to receive either necitumumab plus pemetrexed and cisplatin (n=315) or pemetrexed and cisplatin alone (n=318). Enrolment was stopped on Feb 2, 2011, after a recommendation from the independent data monitoring committee. There was no significant difference in overall survival between treatment groups, with a median overall survival of 11·3 months (95% CI 9·5-13·4) in the necitumumab plus pemetrexed and cisplatin group versus 11·5 months (10·1-13·1) in the pemetrexed and cisplatin group (hazard ratio 1·01 [95% CI 0·84-1·21]; p=0·96). The incidence of grade 3 or worse adverse events, including deaths, was higher in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group; in particular, deaths regarded as related to study drug were reported in 15 (5%) of 304 patients in the necitumumab group versus nine (3%) of 312 patients in the pemetrexed and cisplatin group. Serious adverse events were likewise more frequent in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group (155 [51%] of 304 vs 127 [41%] of 312 patients). Patients in the necitumumab plus pemetrexed and cisplatin group had more grade 3-4 rash (45 [15%] of 304 vs one [<1%] of 312 patients in the pemetrexed and cisplatin alone group), hypomagnesaemia (23 [8%] vs seven [2%] patients), and grade 3 or higher venous thromboembolic events (23 [8%] vs 11 [4%] patients) than did those in the pemetrexed and cisplatin alone group., Interpretation: Our findings show no evidence to suggest that the addition of necitumumab to pemetrexed and cisplatin increases survival of previously untreated patients with stage IV non-squamous NSCLC. Unless future studies identify potentially useful predictive biomarkers, necitumumab is unlikely to provide benefit in this patient population when combined with pemetrexed and cisplatin., Funding: Eli Lilly and Company., (Copyright © 2015 Elsevier Ltd.

Background: Electronic noses are composites of nanosensor arrays. Numerous studies showed their potential to detect lung cancer from breath samples by analysing exhaled volatile compound pattern ("breathprint"). Expiratory flow rate, breath hold and inclusion of anatomic dead space may influence the exhaled levels of some volatile compounds; however it has not been fully addressed how these factors affect electronic nose data. Therefore, the aim of the study was to investigate these effects., Methods: 37 healthy subjects (44 ± 14 years) and 27 patients with lung cancer (60 ± 10 years) participated in the study. After deep inhalation through a volatile organic compound filter, subjects exhaled at two different flow rates (50 ml/sec and 75 ml/sec) into Teflon-coated bags. The effect of breath hold was analysed after 10 seconds of deep inhalation. We also studied the effect of anatomic dead space by excluding this fraction and comparing alveolar air to mixed (alveolar + anatomic dead space) air samples. Exhaled air samples were processed with Cyranose 320 electronic nose., Results: Expiratory flow rate, breath hold and the inclusion of anatomic dead space significantly altered "breathprints" in healthy individuals (p < 0.05), but not in lung cancer (p > 0.05). These factors also influenced the discrimination ability of the electronic nose to detect lung cancer significantly., Conclusions: We have shown that expiratory flow, breath hold and dead space influence exhaled volatile compound pattern assessed with electronic nose. These findings suggest critical methodological recommendations to standardise sample collections for electronic nose measurements.

Objectives: Erlotinib is an epidermal growth factor receptor tyrosine-kinase inhibitor (EGFR-TKI), used for the treatment of non-small cell lung cancer. As the clinical significance of KRAS mutational status has not yet been clearly determined in this setting, our aim was to investigate the efficacy of erlotinib in advanced KRAS mutation-negative lung adenocarcinoma patients., Materials and Methods: MOTIVATE is an open-label, multicenter, observational trial with Tarceva(®) (erlotinib) monotherapy. Enrolled patients with advanced (stage IIIB/IV) KRAS wild type (WT) lung adenocarcinoma refractory to one or two courses of prior chemotherapy were treated with erlotinib at 150mg/day. The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS) and best tumor response rate (RR)., Results and Conclusion: In total, 327 patients were included. Median PFS and OS were 3.3 and 14.4 months, respectively. Three patients (1.2%) had complete response, 51 patients (20.2%) had partial response and 123 patients (48.8%) had SD. Significantly longer median PFS and OS were observed in Eastern Oncology Cooperative Group Performance Status (ECOG PS) 0-1 patients, as compared to ECOG PS 2-3 patients. The longest median OS (20.5 months) was found in patients with ECOG PS 0-1 who received erlotinib as a second-line therapy. There was no difference in median OS in cohorts stratified to disease stage and smoking status. Female patients had both longer median PFS and OS. Disease control rate was 70.2%. Our results suggest that erlotinib represents a valid treatment option for patients with KRAS WT lung adenocarcinoma and, moreover, that KRAS mutation analysis could help to identify clinically relevant subgroups of NSCLC patients that may benefit from EGFR-TKI therapy., (Copyright © 2014 Elsevier Ireland Ltd.

Castleman disease (CD), described as a heterogeneous lymphoproliferative disorder, can be divided into different subtypes according to clinical appearance (unicentric and multicentric form) and histopathological features (hyaline vascular, plasma cell, mixed type, human herpesvirus 8-associated and multicentric not otherwise specified). Unicentric CD is known to be usually of the hyaline vascular variant, plasma cell and mixed type of this form are quite uncommon. Malignancies are mainly associated with the multicentric form. We report a rare case of unicentric mixed variant CD evolving into intrabronchial, extramedullary plasmacytoma.Intrabronchial mass with consequential obstruction of the left main bronchus, left lung atelectasis and mediastinal lymphadenomegaly was detected by chest CT in our patient suffering from cough and hemoptysis. Pulmonectomy was performed, histopathological and immunhistochemical analysis of lymph nodes revealed mixed type of CD with interfollicular monotypic plasma cell proliferation. The intrabronchial mass consisted of monotypic plasma cells confirming plasmacytoma. Systemic involvement was not confirmed by further tests.Although malignancies more often present in multicentric CD that usually belongs to the plasma cell subtype, this case confirms the neoplastic potential of the rarest, unicentric mixed variant of CD., Virtual Slides: The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/2872096831190851.

We report a 52-year-old patient who developed B-cell non-Hodgkin's lymphoma subsequent to sarcoidosis. Sarcoidosis was diagnosed 16 years ago and remained asymptomatic for 14 years after steroid treatment. She presented with new symptoms of arthralgia, photosensitivity, butterfly erythema, autoimmune antibodies (ANA, chromatin positivity) associated with progression of the known left upper lobe lesion on the chest X-ray suggesting primary autoimmune disease (systemic lupus erythematosus). As steroid treatment was not effective, we started bolus cyclophosphamide therapy after which progression was seen on the chest X-ray. Computed tomography (CT)-guided needle biopsy confirmed malignancy of indefinable origin. Despite of the well-known fluorodeoxyglucose (FDG) avidity in active sarcoidosis, a FDG-positron emission tomography (PET) scan was performed to stage the primary tumour. Intensive FDG uptake was detected in the affected lung segment, with moderate uptake in mediastinal lymph nodes. The patient underwent left upper lobectomy. The histology showed pulmonary mucosa-associated lymphoma (bronchus-associated lymphoid tissue (BALT) lymphoma) in the lung tissue, while only sarcoidosis was present in the mediastinal lymph nodes. Bone marrow biopsy was negative.The association between sarcoidosis and lymphoma is known as sarcoidosis lymphoma syndrome, which is a rare disease. PET-CT was helpful in the differentiation of sarcoidosis and malignancy in this patient. It is important to be aware of the risk of lymphoma in sarcoidosis and FDG-PET, used for adequate purpose, can help the diagnosis.

Active oncotherapy, combination chemotherapy of lung cancer is accompanied with many side effects which may impair patients' quality of life and compromise the effectiveness of chemotherapy. Most side effects of chemotherapy are preventable or treatable with optimal supportive care which enhances success in patient care and treatment. The aim of this review is to summarize the most important conditions that may be associated with combined chemotherapy of lung cancer from the practical point of view.

The authors give an overview about the novel results and shifting paradigm of lung cancer screening. They also summarize the results of previous and most recent clinical trials, which re-directed the international interest on lung cancer screening.

The inducible heat shock protein (HSP)72 plays a central role in antitumor immunomodulation. HSP72 expression was assessed on tumor samples of 43 patients with advanced and metastatic small cell lung cancer (SCLC) by immunohistochemistry and HSP72 [HSPA1B A(1267)G] polymorphism was determined. HSP72 expression of SCLC cells was significantly decreased in GG as compared to cells of AA or AG genotype patients, and was associated with significantly shorter survival in GG patients as compared to carriers of the A allele. Decreased HSP72 expression of SCLC cells associated with HSP72 GG genotype is a negative prognostic factor for survival in SCLC patients.

Purpose: This phase III trial was conducted to test whether the novel vascular disrupting agent ASA404 (vadimezan), when combined with first-line platinum-based chemotherapy, improves survival in patients with advanced non-small-cell lung cancer (NSCLC) versus chemotherapy alone., Patients and Methods: Patients with advanced stage IIIB or IV NSCLC, stratified by sex and tumor histology, were randomly assigned 1:1 to paclitaxel (200 mg/m(2)) and carboplatin (area under the curve, 6.0) with or without ASA404 (1,800 mg m(2)), given intravenously once every 3 weeks for six cycles followed by maintenance ASA404 or placebo. Primary end point was overall survival (OS); secondary end points included overall response rate (ORR) and progression-free survival (PFS)., Results: One thousand two hundred ninety-nine patients were randomly assigned. The trial was stopped for futility at interim analysis. At final analysis, there was no difference in OS seen between ASA404 (n = 649) and placebo (n = 650) arms: median OS was 13.4 and 12.7 months respectively (hazard ratio [HR], 1.01; 95% CI, 0.85 to 1.19; P = .535). Similarly, no OS difference was seen in the histologic (squamous or nonsquamous) and sex (male or female) strata. Median PFS was 5.5 months in both arms (HR, 1.04; P = .727), while ORR was 25% in both arms (P = 1.0). Overall rate of adverse events (AEs) was comparable between the ASA404 and placebo arms. Grade 4 neutropenia (27% v 19%) and infusion site pain (10% v 0.5%) were reported more frequently in the ASA404 arm., Conclusion: The addition of ASA404 to carboplatin and paclitaxel, although generally well tolerated, failed to improve frontline efficacy in advanced NSCLC.

Objective: Lung cancer carries a relatively high risk of chemotherapy-induced anemia, one of the most frequent hematological complications. Previous data show a lack of optimal anemia correction in patients with chemotherapy-induced anemia. This paper analyzes real-life data considering the prevalence and severity of chemotherapy-induced anemia, together with the frequency and efficacy of erythropoietin treatment of anemia in Hungarian lung cancer patients., Research Design and Methods: Data of 482 patients with histological or cytological confirmed lung cancer receiving chemotherapy were collected retrospectively between 1 January and 31 December, 2008. In all, 83 (17%) of them developed chemotherapy-induced moderate to severe anemia (44.6% male, 55.4% female; mean age 70 ± 8.6 years; NSCLC 67.5%, small cell lung cancer 32.5%)., Results: More than 50% of the patients suffering from moderate to severe chemotherapy-induced anemia (hemoglobin below 10 g/dl) did not receive erythropoietin treatment. Chemotherapy had to be postponed due to anemia in 32.26% of the patients receiving erythropoietin supplementation, while this was seen in 41.94% of the group without erythropoietin treatment (p < 0.05). In patients not receiving erythropoietin, the severity of anemia increased, while erythropoietin treated patients maintained acceptable hemoglobin levels after the end of the chemotherapy., Conclusions: The data draws attention to the fact that nowadays chemotherapy-induced anemia is not treated according to current guidelines in many lung cancer cases in Hungary.

Platinum-based chemotherapies are widely used in the treatment of lung cancer. However, little is known about their effect in the expression of certain tissue biomarkers. We have studied the ERCC1 (excision repair cross-complementation group 1) expression in tissue samples of patients treated with neoadjuvant chemotherapy. Fifty lung cancer tissue blocks of 25 patients (15 males, 10 females) were studied. They included 25 bronchoscopic biopsies (14 squamous cell carcinomas and 11 adenocarcinomas) together with their corresponding surgical biopsies after neoadjuvant chemotherapy. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded tissues to study the expression of ERCC1. Staining scores (0-300) were calculated by multiplying the percentage of positive tumor cells (0-100) by the staining intensity (0-3). All but one bronchosopic squamous cell carcinoma tissues (13/14) expressed ERCC1. Four of these cases became negative after neoadjuvant therapy, and in 8 cases the level of expression decreased. In the adenocarcinoma group all but one bronchosopic tissues (10/11) expressed ERCC1. Six of these cases became negative after neoadjuvant therapy, and in 4 cases the level of expression decreased. Comparison of staining scores before and after chemotherapy revealed more pronounced decrease in adenocarcinomas and in female patients. There was no newly expressed ERCC1-positive case in the surgical biopsy group. The results of the present study suggest that platinum-based chemotherapy affects the expression of tissue biomarker (ERCC1) which may have predictive value, and probably induces a selection of tumor cells with more aggressive phenotype. This knowledge might be of importance when designing treatment protocols for non-small cell lung cancer patients.

Anti-citrullinated protein antibodies (ACPAs), produced against citrullinated proteins, are diagnostic and prognostic markers of rheumatoid arthritis (RA). The underlying mechanism that explains the connection of smoking, citrullination [catalyzed by peptidyl arginine deiminases (PADs)] and ACPAs is still unclarified in RA. Thus, we searched for a non-arthritic model in which an increased cell death allows the formation of autoantibodies. Data supporting that lung cancer might be a good candidate are as follows: (i) smoking plays a role in its pathogenesis, (ii) the disease is frequently accompanied by paraneoplastic syndrome, (iii) smoking increases citrullination in the lung, (iv) various types of malignancies are associated with increased citrullination and (v) lung cancer tissue shows similarities with RA synovium. Serum PAD4, rheumatoid factor (RF) and ACPA levels were measured in 42 lung cancer patients; expression of cytokeratin 7 (CK7), PAD4 and citrullinated proteins was visualized in 113 lung cancer tissues. All parameters were analyzed in correlation with smoking history. None of the patients had polyarthritis or autoimmune disease. Significantly increased RF levels were associated with higher PAD4 levels in smoker lung cancer patients compared with non-smokers. Both PAD4 and citrullination immunostaining strongly correlated with that of CK7 in lung cancer, however, did not differ according to smoking history. Two of 30 smoker lung cancer patients had high anti-cyclic citrullinated peptide levels. In conclusion, PAD4 and citrullination may be helpful in distinguishing lung cancer from healthy tissue. Smoking, abnormal serum PAD4 and RF levels may not be sufficient for the production of ACPAs and development of autoimmunity.

Ageing lung cancer patients may be at increased risk of Cisplatin (Cp) nephrotoxicity, because of comorbidities leading to accelerated ageing of the kidneys. Therefore, the Cp-induced impairement of renal function was compared between no comorbidity (NC) and hypertension plus ischaemic heart disease (CD) patients or others having diabetes mellitus plus ischaemic heart disease (DMIH). In a preliminary study, glomerular filtration rate (GFR) was measured by clearance of technetium 99m-labelled diethylene-thiamine penta-acetate in 38 lung cancer patients with normal serum creatinine concentration ([creat]). Then, the incidence of nephrotoxicity was analysed retrospectively over 1st-4th cycles of Cp treatment among 242 lung cancer patients with initially normal [creat]. GFR was repeatedly estimated using calculated creatinine clearance. Pre-treatment GFR was 57 ± 3 mL·min⁻¹·m⁻² in those with normal (n = 15) and 42 ± 2 mL·min⁻¹·m⁻² in those with pathologically increased (n = 23) [creat] any time following their 2nd-4th Cp cycle (p < 0.05). The retrospective analysis revealed that Cp-induced nephrotoxicity developed in 7.5% of the NC (n = 80), in 20.9% of the CD (n = 110) and in 30.8% of the DMIH (n = 52) subgroups. Within the overall dropout rate from further Cp chemotherapy, nephrotoxicity was responsible in 14% of NC, 38% in CD and 75% in DMIH patients. A major portion of our ageing lung cancer patients suffered from comorbidities leading to reduced renal resistance to Cp nephrotoxicity.

High-dose (75 mg/m2) cisplatin is baseline chemotherapy in lung cancer. To prevent nephrotoxicity, patients generally receive saline infusion on the day of chemotherapy prior to and following cisplatin (total of 3.5-4.0 liters during 3-4 hours). Despite these measures nephrotoxicity has remained frequent, especially among patients also suffering from cardiovascular disease or diabetes mellitus. Since 2005 several international recommendations have been formed about prevention of cisplatin nephrotoxicity. According to these recommendations: 1) renal function should not be evaluated by serum creatinine concentration; 2) evaluation of renal function should be based on calculated creatinine clearance (e.g. by the Cockcroft-Gault equation); 3) patients to be treated by high-dose cisplatin should be euvolemic and should have saline diuresis (urine NaCl concentration ~1%) of at least 100 ml/hour prior to, during and several days following the administration of cisplatin. Keeping these recommendations ensures prolonged cisplatin treatability of lung cancer patients. Moreover, decreased renal function will not limit the full dose administration of several other cytotoxic agents. Losonczy G, Máthé C, Müller V, Szondy K, Moldvay J. Incidence, risk factors and prevention of cisplatin-induced nephrotoxicity in patients with lung cancer.

Chemotherapies are widely used in the treatment of lung cancer. However, little is known about their effect in the expression of different tissue markers. Seventeen lung cancer tissue blocks obtained by bronchoscopic biopsies together with their corresponding surgical biopsies after neoadjuvant chemotherapy were studied. They included 9 adenocarcinomas (ADC) and 8 squamous cell carcinomas (SCC). Immunohistochemistry was performed on formalin-fixed, paraffin-embedded tissues to study the expression of Ki-67, p53, Bcl-2, Bax, Fas-ligand and ERCC1 (excision repair cross-complementation group 1). Out of 17 NSCLC 6 expressed proapoptotic markers and 4 expressed antiapoptotic markers, while in 7 cases the apoptotic markers did not show detectable changes after neoadjuvant chemotherapy. Six of 17 bronchoscopic NSCLC cases expressed increased level of Ki-67 after neoadjuvant treatment. Eight bronchoscopic NSCLC tissues (6 SCC, 2 ADC) expressed ERCC1. All but one ADC became ERCC1 negative after neoadjuvant therapy. There was no newly expressed ERCC1 positive case in the surgical biopsy group. Platinum-based neoadjuvant chemotherapy had no effect on the apoptotic activity of 17 patients' tumor specimen, however, 6 of 17 bronchoscopic NSCLC cases expressed increased level of Ki-67 after neoadjuvant treatment, in 3 cases the level of Ki-67 became decreased, while 8 cases had no detectable change of proliferation activity. The results of the present study suggest that platinum-based chemotherapy probably induces a selection of tumor cells with more aggressive phenotype, and also affects the expression of tissue marker (ERCC1) that could have predictive value.

Lung cancer is the leading cause of cancer death. Results of therapeutic interventions are particularly discouraging when the disease is discovered in an advanced stage. Early diagnosis is limited by the fact that the disease usually develops asymptomatically and available screening methods do not fulfil the requirements for reliable discrimination between patients with lung cancer and subjects not suffering from the disease. Breath sampling is completely noninvasive and provides a potentially useful approach to screening lung cancer. Exhaled biomarkers contain both volatile and nonvolatile molecules. The profile of volatile organic compounds is different in patients with lung cancer than in control subjects. In exhaled breath condensate, the proteomic profile of breath from cancer patients differs from that of healthy smokers. We reviewed the scientific evidence demonstrating that a unique chemical signature can be detected in the breath of patients with lung cancer and that the exhaled breath biomarker profile could aid clinical decision making.

Anemia is common among patients with malignant tumors, due to the disease and chemotherapy. Anemia decreases patient's quality of life, and worsens the dose intensity of chemotherapy. The aim of this retrospective data-analysis was to determine the rate of transfusions and the maintenance of chemotherapeutic dose intensity in 9 small cell lung cancer patients receiving beta-erythropoietin, due to anemia observed after the first cycle of chemotherapy. The mean pre-treatment hemoglobin concentration of the patients was 116.67+/-8.17 g/L (mean+/-SD). The mean pre-erythropoietin hemoglobin concentration at baseline was 103.11+/-7.52 g/L. Six cycles of platinum compounds and etoposide were used. The post-treatment hemoglobin concentration of patients was 110.11+/-5.37 g/L (p = 0,028 vs. baseline). During these 54 chemotherapeutic cycles, only 2 patients needed transfusion, each of them once. According to our experience, the use of beta-erythropoietin in 9 anemic small cell lung cancer patients resulted in a low rate of transfusions and maintenance of cytotoxic treatment dose intensity. The adequate use of beta-erythropoietin is of great help to the physician in the management of small cell lung cancer patients.
