[PMID: 26973324 PMCID: PMC5063047 DOI: 10.1016/s1470-2045(15)00614-2] [Citation(s) in RCA: 349] [Impact Index Per Article: 43.6] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2015] [Revised: 12/14/2015] [Accepted: 12/16/2015] [Indexed: 01/18/2023]
Abstract
BACKGROUND ALK-rearranged non-small-cell lung cancer (NSCLC) is sensitive to ALK tyrosine kinase inhibitors (ALK inhibitors) such as crizotinib, but resistance invariably develops, often with progression in the brain. Ceritinib is a more potent ALK inhibitor than crizotinib in vitro, crosses the blood-brain barrier in vivo, and shows clinical responses in patients with crizotinib-resistant disease. We aimed to assess whole-body activity of ceritinib in both ALK inhibitor-pretreated and ALK inhibitor-naive patients with ALK-rearranged NSCLC. METHODS ASCEND-1 was an open-label, phase 1 trial that recruited patients from 20 academic hospitals or cancer centres in 11 countries in Europe, North America, and Asia-Pacific. Eligible patients were aged 18 years or older with ALK-rearranged locally advanced or metastatic cancer that had progressed despite standard therapy (or for which no effective standard therapy existed), who had at least one measurable lesion at baseline. The primary objective (to determine the maximum tolerated dose) has been reported previously. This updated analysis includes all patients with ALK-rearranged NSCLC given oral ceritinib at the recommended dose of 750 mg/day in the dose-escalation and expansion phases. Here we report the secondary outcomes of overall response, duration of response, and progression-free survival, analysed in all patients who received at least one 750 mg dose of ceritinib. Exploratory analyses included retrospective analysis of intracranial activity by independent neuroradiologists, in patients with untreated or locally treated neurologically stable brain metastases at baseline. Safety was assessed in all patients who received at least one dose of ceritinib. This study is no longer recruiting patients; however, treatment and follow-up are ongoing. This study is registered with ClinicalTrials.gov, number NCT01283516. FINDINGS Between Jan 24, 2011, and July 31, 2013, 255 patients were enrolled and received at least one dose of ceritinib 750 mg/day, of whom 246 had ALK-rearranged NSCLC. At data cutoff (April 14, 2014), median follow-up was 11·1 months (IQR 6·7-15·2) and 147 (60%) patients had discontinued treatment, 98 (40%) as a result of disease progression. An overall response was reported in 60 (72% [95% CI 61-82]) of 83 ALK inhibitor-naive patients and 92 (56% [49-64]) of 163 ALK inhibitor-pretreated patients. Median duration of response was 17·0 months (95% CI 11·3-non-estimable [NE]) in ALK inhibitor-naive patients and 8·3 months (6·8-9·7) in ALK inhibitor-pretreated patients. Median progression-free survival was 18·4 months (95% CI 11·1-NE) in ALK inhibitor-naive patients and 6·9 months (5·6-8·7) in ALK inhibitor-pretreated patients. Of 94 patients with retrospectively confirmed brain metastases and at least one post-baseline MRI or CT tumour assessment, intracranial disease control was reported in 15 (79% [95% CI 54-94]) of 19 ALK inhibitor-naive patients and in 49 (65% [54-76]) of 75 ALK inhibitor-pretreated patients. Of these 94 patients, 11 had measurable brain lesions and no previous radiotherapy to the brain, six of whom achieved a partial intracranial response. Serious adverse events were recorded in 117 (48%) of 246 patients. The most common grade 3-4 laboratory abnormalities were increased alanine aminotransferase (73 [30%] patients) and increased aspartate aminotransferase (25 [10%]). The most common grade 3-4 non-laboratory adverse events were diarrhoea and nausea, both of which occurred in 15 (6%) patients. Two on-treatment deaths during the study were deemed to be related to study drug by the investigators, one due to interstitial lung disease and one as a result of multiorgan failure that occurred in the context of infection and ischaemic hepatitis. INTERPRETATION The durable whole-body responses reported, together with the intracranial activity, support a clinical benefit for treatment with ceritinib in patients with ALK-rearranged NSCLC who have received crizotinib, or as an alternative to crizotinib. A confirmatory phase 2 clinical trial is ongoing to assess ceritinib activity in patients with ALK-rearranged NSCLC and brain or leptomeningeal metastases.

Abstract
BACKGROUND Unplanned hospital admissions (UHAs) are frequent in lung cancer, but literature on this topic is scarce. The aim of this study is to gain insight in the demographics, patterns of referral, causes, presenting symptoms, and final outcome of these UHAs. A strategy to improve quality of care and reduce the number and cost of UHAs was suggested based upon these findings. PATIENTS AND METHODS In retrospective analysis of all consecutive UHAs in a 6-month period in a tertiary center, demographics, pattern of referral, clinical data, tumor control status, final diagnosis, duration of hospitalization, and outcome were examined. RESULTS Two hundred seven UHAs were recorded. Male/female ratio was 185/62, mean age 65.5 years, performance status (PS) on admission 0-1 in 32 %, 2 in 37.2 %, and 3-4 in 30.8 % of patients. Patient referral occurred by general practitioner in 33.6 % or specialist in 25.5 % and in 40.9 % on own initiative. UHAs were therapy-related in 23.9 %, cancer-related in 47.4 %, comorbidity-related in 19.4 %, or of unclear nature in 9.3 %. Most frequent causes were infections (21.9 %) and respiratory problems (17.0 %). Mean length of stay was 9.5 days. Final outcome was 10.1 % mortality, 6.9 % hospice care transfers, and 79.4 % home returns (including 18.2 % same day returns). CONCLUSION UHAs in lung cancer were more cancer- than therapy-related. Majority of patients (2/3) were not seen by their general practitioner. A significant number of same day returns were noted. UHAs in patients with poor PS, uncontrolled cancer and cancer-related events had the worst outcome. This work is a first step in identifying specific characteristics of UHAs in lung cancer patients, which may lead to strategies to reduce the burden of UHAs.

Abstract
PURPOSE The phase III PROCLAIM study evaluated overall survival (OS) of concurrent pemetrexed-cisplatin and thoracic radiation therapy (TRT) followed by consolidation pemetrexed, versus etoposide-cisplatin and TRT followed by nonpemetrexed doublet consolidation therapy. PATIENTS AND METHODS Patients with stage IIIA/B unresectable nonsquamous non-small-cell lung cancer randomly received (1:1) pemetrexed 500 mg/m(2) and cisplatin 75 mg/m(2) intravenously every 3 weeks for three cycles plus concurrent TRT (60 to 66 Gy) followed by pemetrexed consolidation every 3 weeks for four cycles (arm A), or standard therapy with etoposide 50 mg/m(2) and cisplatin 50 mg/m(2) intravenously, every 4 weeks for two cycles plus concurrent TRT (60 to 66 Gy) followed by two cycles of consolidation platinum-based doublet chemotherapy (arm B). The primary objective was OS. The study was designed as a superiority trial with 80% power to detect an OS hazard ratio of 0.74 with a type 1 error of .05. RESULTS Enrollment was stopped early because of futility. Five hundred ninety-eight patients were randomly assigned (301 to arm A, 297 to arm B) and 555 patients (283 in arm A, 272 in arm B) were treated. Arm A was not superior to arm B in terms of OS (hazard ratio, 0.98; 95% CI, 0.79 to 1.20; median, 26.8 v 25.0 months; P = .831). Arm A had a significantly lower incidence of any drug-related grade 3 to 4 adverse events (64.0% v 76.8%; P = .001), including neutropenia (24.4% v 44.5%; P < .001), during the overall treatment period. CONCLUSION Pemetrexed-cisplatin combined with TRT followed by consolidation pemetrexed was not superior to standard chemoradiotherapy for stage III unresectable nonsquamous non-small-cell lung cancer.

Abstract
INTRODUCTION Small cell lung cancer (SCLC) is commonly classified as either limited or extensive, but the Union for International Cancer Control TNM Classification of Malignant Tumours seventh edition (2009) recommended tumor, node, and metastasis (TNM) staging based on analysis of the International Association for the Study of Lung Cancer (IASLC) database. METHODS Survival analyses were performed for clinically and pathologically staged patients presenting with SCLC from 1999 through 2010. Prognosis was compared in relation to the TNM seventh edition staging to serve as validation and analyzed in relation to proposed changes to the T descriptors found in the eighth edition. RESULTS There were 5002 patients: 4848 patients with clinical and 582 with pathological stages. Among these, 428 had both. Survival differences were confirmed for T and N categories and maintained in relation to proposed revisions to T descriptors for seventh edition TNM categories and proposed changes in the eighth edition. There were also survival differences, notably at 12 months, in patients with brain-only single-site metastasis (SSM) compared to SSM at other sites, and SSM without a pleural effusion showed a better prognosis than other patients in the M1b category. CONCLUSION We confirm the prognostic value of clinical and pathological TNM staging in patients with SCLC, and recommend continued usage for SCLC in relation to proposed changes to T, N, and M descriptors for NSCLC in the eighth edition. However, for M descriptors, it remains uncertain whether survival differences in patients with SSM in the brain simply reflect better treatment options rather than better survival based on anatomic extent of disease.

Abstract
PURPOSE Limited data are available to describe the effectiveness of darbepoetin alfa (DA) in terms of hemoglobin (Hb) and transfusion outcomes when initiated at Hb ≤10 g/dL (the threshold specified in the summary of prescribing characteristics). We assessed DA, initiated according to current labeling (Hb ≤10 g/dL), in chemotherapy-induced anemia (CIA). METHODS Data for patients with cancer and CIA who initiated DA at Hb ≤10 g/dL were extracted from a database of Amgen-sponsored trials. A comparative analysis was limited to randomized, controlled trials in patients treated with DA or control (placebo/best supportive care). Data for the DA arm(s) of randomized, multiple-arm, or prospective, single-arm trials were also extracted (DA-only analysis; non-front-loaded studies only). Outcomes included Hb increase ≥1 g/dL or ≥2 g/dL during the first 12 weeks of treatment. Crude and Kaplan-Meier proportions of patients who experienced each outcome and time (days) to each outcome were summarized by treatment arm. Meta-analysis (fixed-effects inverse-variance method) was performed to compare outcomes for DA with control. FINDINGS The comparative analysis included 4 studies (2 in lung cancer, 1 in lymphoproliferative disease, and 1 in non-myeloid malignancy: DA, n = 261; control, n = 273). The DA-only analysis included 15 studies (n = 3768). In comparative analyses, more patients who received DA than placebo achieved Hb increase of ≥1 g/dL (fixed-effects hazard ratio [HR] = 2.07; 95% CI, 1.62-2.63) or ≥2 g/dL (HR = 2.91; 95% CI, 2.09-4.06). Median times to ≥1 g/dL or ≥2 g/dL increase were 43 or 78 days for DA (not evaluable for placebo). Transfusions were less common in patients who received DA (HR = 0.58; 95% CI, 0.44-0.77). Addition of 2 dose-finding studies did not change the findings of the main comparative analysis. Results were similar in the DA-only analyses. IMPLICATIONS This is the first patient-level meta-analysis, to our knowledge, to evaluate the efficacy in terms of Hb response of DA treatment when initiated according to current product labeling in patients with CIA. Limitations include the small number of studies and patients eligible for inclusion in the comparative analyses and the absence of non-Amgen trials of DA. The results of the comparative analysis confirm that DA is more effective than placebo at increasing serum Hb levels and at reducing the need for transfusion in patients with CIA when treatment is initiated at Hb ≤10 g/dL, as per current product labeling.

Abstract
(18)F-fluoro-2-deoxy-d-glucose positron emission tomography (PET) complements conventional imaging for diagnosing and staging lung cancer. Two literature-based meta-analyses suggest that maximum standardised uptake value (SUVmax) on PET has univariate prognostic value in nonsmall cell lung cancer (NSCLC). We analysed individual data pooled from 12 studies to assess the independent prognostic value of binary SUVmax for overall survival.After searching the published literature and identifying unpublished data, study coordinators were contacted and requested to provide data on individual patients. Cox regression models stratified for study were used.Data were collected for 1526 patients (median age 64 years, 60% male, 34% squamous cell carcinoma, 47% adenocarcinoma, 58% stage I-II). The combined univariate hazard ratio for SUVmax was 1.43 (95% CI 1.22-1.66) and nearly identical if the SUV threshold was calculated stratifying for histology. Multivariate analysis of patients with stage I-III disease identified age, stage, tumour size and receipt of surgery as independent prognostic factors; adding SUV (HR 1.58, 95% CI 1.27-1.96) improved the model significantly. The only detected interaction was between SUV and stage IV disease.SUV seems to have independent prognostic value in stage I-III NSCLC, for squamous cell carcinoma and for adenocarcinoma.

Abstract
INTRODUCTION Non-small cell lung cancer (NSCLC) is a heterogeneous disorder consisting of distinct molecular subtypes each characterised by specific genetic and epigenetic profiles. Here, we aimed to identify novel NSCLC subtypes based on genome-wide methylation data, assess their relationship with smoking behaviour, age, COPD, emphysema and tumour histopathology, and identify the molecular pathways underlying each subtype. METHODS Methylation profiling was performed on 49 pairs of tumour and adjacent lung tissue using Illumina 450 K arrays. Transcriptome sequencing was performed using Illumina HiSeq2000 and validated using expression data from The Cancer Genome Atlas (TCGA). Tumour immune cell infiltration was investigated by immunohistochemistry. RESULTS Unsupervised hierarchical clustering of tumour methylation data revealed two subgroups characterised by a significant association between cluster membership and presence of COPD (p=0.024). Ontology analysis of genes containing differentially methylated CpGs (false discovery rate, FDR-adjusted p<0.05) revealed that immune genes were strongly enriched in COPD tumours, but not in non-COPD tumours. This COPD-specific immune signature was attributable to methylation changes in immune genes expressed either by tumour cells or tumour-infiltrating immune cells. No such differences were observed in adjacent tissue. Transcriptome profiling similarly revealed that genes involved in the immune response were differentially expressed in COPD tumours (FDR-adjusted p<0.05), an observation that was independently replicated using TCGA data. Immunohistochemistry validated these findings, revealing fewer CD4-positive T lymphocytes in tumours derived from patients with COPD. CONCLUSIONS Lung tumours of patients with COPD differ from those of patients without COPD, with differentially methylated and expressed genes being mainly involved in the immune response.

Abstract
BACKGROUND Selumetinib (AZD6244, ARRY-142886)+docetaxel increases median overall survival (OS) and significantly improves progression-free survival (PFS) and objective response rate (ORR) compared with docetaxel alone in patients with KRAS mutant, stage IIIB/IV non-small-cell lung cancer (NSCLC; NCT00890825). METHODS Retrospective analysis of OS, PFS, ORR and change in tumour size at week 6 for different sub-populations of KRAS codon mutations. RESULTS In patients receiving selumetinib+docetaxel and harbouring KRAS G12C or G12V mutations there were trends towards greater improvement in OS, PFS and ORR compared with other KRAS mutations. CONCLUSION Different KRAS mutations in NSCLC may influence selumetinib/docetaxel sensitivity.

Abstract
Background Treatment decisions in advanced non-small cell lung cancer rely on accurate analysis of the EGFR mutation status in small tissue samples. Sanger sequencing of PCR products is unbiased and cheap, but its detection threshold requiring 20 % infiltration by malignant cells is not optimal. Commercial kits, based on quantitative real-time PCR have better detection limits and can detect a wide spectrum of mutations but are considerably more expensive. Methods We developed a wild-type blocking PCR for EGFR G719A/S/C (exon 18), exon 19 deletions, and exon 20 insertions using locked nucleic acid (LNA) probes. The amplification products of positive reactions were analyzed by Sanger sequencing. We retrospectively validated this assay by comparison of the EGFR mutation status as obtained with Fragment Length Analysis and the Therascreen EGFR RGQ PCR kit. Results The EGFR mutation status for exon 18 and 19 as obtained with the LNA-PCR/sequencing assay correlated adequately with the results obtained by the other independent methods. Due to the lack of structural consistency among the insertions in exon 20, the latter are less amenable for a LNA-PCR design. Conclusions The LNA-PCR/sequencing assay presented here is specific, sensitive, and has a low detection threshold. In combination with allele-specific PCR reactions for T790M (exon 20) and L858R (exon 21), a wider scope of EGFR mutations can be assessed at a lower cost.

Abstract
ABSTRACT In the past decade, the approach to patients with metastatic non-small-cell lung cancer has relied on chemotherapy and on targeted agents for molecularly selected subgroups of patients. Recent work has introduced immunotherapy as another area of progress, and likely as a new treatment paradigm in the near future. While the large Phase III studies with cancer vaccination with the current technologies remain at present disappointing, the immunomodulation strategies with immune checkpoint inhibitors have delivered remarkable results in expanded Phase I studies and are now intensively studied in large Phase III studies. This review summarizes the past decade of immunotherapy for non-small-cell lung cancer, gives an updated overview of trials in this field, and the context of future development in this exciting field.

Abstract
BACKGROUND This multicentre, open-label, randomized, controlled phase II study evaluated cilengitide in combination with cetuximab and platinum-based chemotherapy, compared with cetuximab and chemotherapy alone, as first-line treatment of patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients were randomized 1:1:1 to receive cetuximab plus platinum-based chemotherapy alone (control), or combined with cilengitide 2000 mg 1×/week i.v. (CIL-once) or 2×/week i.v. (CIL-twice). A protocol amendment limited enrolment to patients with epidermal growth factor receptor (EGFR) histoscore ≥200 and closed the CIL-twice arm for practical feasibility issues. Primary end point was progression-free survival (PFS; independent read); secondary end points included overall survival (OS), safety, and biomarker analyses. A comparison between the CIL-once and control arms is reported, both for the total cohorts, as well as for patients with EGFR histoscore ≥200. RESULTS There were 85 patients in the CIL-once group and 84 in the control group. The PFS (independent read) was 6.2 versus 5.0 months for CIL-once versus control [hazard ratio (HR) 0.72; P = 0.085]; for patients with EGFR histoscore ≥200, PFS was 6.8 versus 5.6 months, respectively (HR 0.57; P = 0.0446). Median OS was 13.6 for CIL-once versus 9.7 months for control (HR 0.81; P = 0.265). In patients with EGFR ≥200, OS was 13.2 versus 11.8 months, respectively (HR 0.95; P = 0.855). No major differences in adverse events between CIL-once and control were reported; nausea (59% versus 56%, respectively) and neutropenia (54% versus 46%, respectively) were the most frequent. There was no increased incidence of thromboembolic events or haemorrhage in cilengitide-treated patients. αvβ3 and αvβ5 expression was neither a predictive nor a prognostic indicator. CONCLUSIONS The addition of cilengitide to cetuximab/chemotherapy indicated potential clinical activity, with a trend for PFS difference in the independent-read analysis. However, the observed inconsistencies across end points suggest additional investigations are required to substantiate a potential role of other integrin inhibitors in NSCLC treatment. CLINICAL TRIAL REGISTRATION ID NUMBER NCT00842712.

Abstract
PURPOSE MAPK and PI3K/AKT/mTOR pathways play important roles in many tumors. In this study, safety, antitumor activity, and pharmacokinetics of buparlisib (pan class PI3K inhibitor) and trametinib (MEK inhibitor) were evaluated. EXPERIMENTAL DESIGN This open-label, dose-finding, phase Ib study comprised dose escalation, followed by expansion part in patients with RAS- or BRAF-mutant non-small cell lung, ovarian, or pancreatic cancer. RESULTS Of note, 113 patients were enrolled, 66 and 47 in dose-escalation and -expansion parts, respectively. MTD was established as buparlisib 70 mg + trametinib 1.5 mg daily [5/15, 33% patients with dose-limiting toxicities (DLT)] and recommended phase II dose (RP2D) buparlisib 60 mg + trametinib 1.5 mg daily (1/10, 10% patients with DLTs). DLTs included stomatitis (8/103, 8%), diarrhea, dysphagia, and creatine kinase (CK) increase (2/103, 2% each). Treatment-related grade 3/4 adverse events (AEs) occurred in 73 patients (65%); mainly CK increase, stomatitis, AST/ALT (aspartate aminotransferase/alanine aminotransferase) increase, and rash. For all (21) patients with ovarian cancer, overall response rate was 29% [1 complete response, 5 partial responses (PR)], disease control rate 76%, and median progression-free survival was 7 months. Minimal activity was observed in patients with non-small cell lung cancer (1/17 PR) and pancreatic cancer (best overall response was SD). Relative to historical data, buparlisib exposure increased and trametinib exposure slightly increased with the combination. CONCLUSIONS At RP2D, buparlisib 60 mg + trametinib 1.5 mg daily shows promising antitumor activity for patients with KRAS-mutant ovarian cancer. Long-term tolerability of the combination at RP2D is challenging, due to frequent dose interruptions and reductions for toxicity.

Abstract
OBJECTIVES Afatinib, an oral irreversible ErbB family blocker, has demonstrated efficacy in patients with epidermal growth factor receptor (EGFR) mutation-positive advanced lung adenocarcinoma. Other potential biomarkers predicting response to afatinib, such as human epidermal growth factor receptor-2 (HER2) mutations and EGFR gene amplification, have not been validated yet. This phase II study investigated whether afatinib conferred clinical benefit in cohorts of adenocarcinoma patients with: (1) EGFR mutation and failing on erlotinib/gefitinib; or (2) increased copy number of EGFR by fluorescence in situ hybridization (FISH); or (3) HER2 mutation. MATERIALS AND METHODS Patients started daily afatinib 50mg monotherapy. Upon disease progression, patients could continue, at the investigator's discretion, afatinib (40mg) with the addition of paclitaxel (80mg/m(2) weekly for 3 weeks/4-week cycle). Endpoints included confirmed objective response (OR), progression-free survival (PFS), disease control, and safety. RESULTS Of 41 patients treated (cohort 1: n=32; cohort 2: n=2; cohort 3: n=7), 33 received afatinib monotherapy; eight subsequently received afatinib plus paclitaxel. With afatinib monotherapy, one patient achieved a confirmed OR (partial response [PR]; cohort 2). Two further patients achieved unconfirmed PRs (one each in cohort 1 and cohort 3). Disease control was achieved by 17/32 (53%), 2/2 (100%) and 5/7 (71%) patients in cohorts 1, 2 and 3, respectively. In patients receiving combination therapy (median PFS: 6.7 weeks), one (cohort 3) had confirmed PR of 41.9 weeks. The most common afatinib-related adverse events were diarrhea (95%) and rash/acne (80%). CONCLUSION Afatinib demonstrated signs of clinical activity in heavily pretreated patients with activating HER2 or EGFR mutations or EGFR FISH-positive tumors.

Abstract
BACKGROUND Biomarker-driven clinical trials in advanced non-small cell lung cancer (NSCLC) usually accept biopsy specimens only, as cytology specimens are supposed to be more challenging due to low neoplastic cell content and suboptimal DNA quantity. OBJECTIVES We aimed to evaluate 2 aspects of bronchoscopic biopsy and cytology specimens: (1) the proportion of neoplastic cells and quantity of DNA extracted, and (2) the detection limit of the Scorpion amplification refractory mutation system on endoscopic samples obtained in daily clinical practice. METHODS We screened 679 patients with advanced-stage NSCLC for the presence of an activating EGFR mutation according to the guidelines of the European Society of Medical Oncology. Their diagnostic tumour tissue samples were characterized. A dilution experiment was performed to determine the minimal proportion of neoplastic cells for a reliable test result. RESULTS Surgical biopsies, bronchoscopic forceps biopsy samples and needle aspiration cytology specimens exhibited a median tumour cell proportion of 70 versus 30 versus 20% and a DNA quantity of 2,500 versus 1,610 versus 1,440 ng, respectively. The overall EGFR mutation rate was 11%, with no differences between different sample types. Dilution experiments showed that the detection limit depends on the type of mutation. A neoplastic cell content of at least 10 and 25% for exon 19 deletions and exon 21 L858R point mutation, respectively, was required for a true negative result. CONCLUSIONS Bronchoscopic forceps biopsy and needle aspiration cytology specimens are suitable for accurate EGFR mutation analysis using single-gene quantitative real-time polymerase chain reaction. Technologies with a better analytical sensitivity are evolving and should consider these endoscopic tumour specimens.

Abstract
Background ESMO consensus recommends EGFR mutation testing in never/former light smokers (<15 pack-years) or patients with non-squamous NSCLC. The aim of this work was to determine the frequency and clinical predictors of EGFR mutations, and the role of specimen sampling tests, in Caucasian standard practice setting. Methods We screened 297 patients according to this consensus. Mutational analysis of EGFR was performed using the Therascreen EGFR RGQ PCR mutation kit. Clinical and pathological correlative data were collected. Results An EGFR activating mutation was found in 32 patients (11%), twelve exon 19 deletions, two exon 18 and eighteen exon 21 point mutations. Most were in females, but half were in smokers. Negative TTF-1 staining had a very strong negative predictive value (all except one patient had TTF-1 positive adenocarcinoma). Both biopsies as well as cytology specimens (mainly EBUS-TBNA) did well: 24 mutations in 213 biopsy samples (11.2%) and 8 in 84 cytology samples (9.5%), respectively. The Therascreen acted as a sensitive test in all types of samples: 7 activating mutations were found in samples rated to have <5% of tumour cells, and there were only 4 test failures in the whole series. Conclusion In this Caucasian standard practice NSCLC cohort, tested according to the ESMO consensus, activating EGFR mutation occurred in 11% of the patients. Half of these were in former/current smokers. With our sampling technique and use of the Therascreen kit, EBUS-TBNA cell blocks performed as good as biopsies.

Abstract
BACKGROUND Non-small-cell lung cancer (NSCLC) harboring the anaplastic lymphoma kinase gene (ALK) rearrangement is sensitive to the ALK inhibitor crizotinib, but resistance invariably develops. Ceritinib (LDK378) is a new ALK inhibitor that has shown greater antitumor potency than crizotinib in preclinical studies. METHODS In this phase 1 study, we administered oral ceritinib in doses of 50 to 750 mg once daily to patients with advanced cancers harboring genetic alterations in ALK. In an expansion phase of the study, patients received the maximum tolerated dose. Patients were assessed to determine the safety, pharmacokinetic properties, and antitumor activity of ceritinib. Tumor biopsies were performed before ceritinib treatment to identify resistance mutations in ALK in a group of patients with NSCLC who had had disease progression during treatment with crizotinib. RESULTS A total of 59 patients were enrolled in the dose-escalation phase. The maximum tolerated dose of ceritinib was 750 mg once daily; dose-limiting toxic events included diarrhea, vomiting, dehydration, elevated aminotransferase levels, and hypophosphatemia. This phase was followed by an expansion phase, in which an additional 71 patients were treated, for a total of 130 patients overall. Among 114 patients with NSCLC who received at least 400 mg of ceritinib per day, the overall response rate was 58% (95% confidence interval [CI], 48 to 67). Among 80 patients who had received crizotinib previously, the response rate was 56% (95% CI, 45 to 67). Responses were observed in patients with various resistance mutations in ALK and in patients without detectable mutations. Among patients with NSCLC who received at least 400 mg of ceritinib per day, the median progression-free survival was 7.0 months (95% CI, 5.6 to 9.5). CONCLUSIONS Ceritinib was highly active in patients with advanced, ALK-rearranged NSCLC, including those who had had disease progression during crizotinib treatment, regardless of the presence of resistance mutations in ALK.

Abstract
To complement the existing treatment guidelines for all tumour types, ESMO organises consensus conferences to focus on specific issues in each type of tumour. The 2nd ESMO Consensus Conference on Lung Cancer was held on 11-12 May 2013 in Lugano. A total of 35 experts met to address several questions on non-small-cell lung cancer (NSCLC) in each of four areas: pathology and molecular biomarkers, first-line/second and further lines in advanced disease, early-stage disease and locally advanced disease. For each question, recommendations were made including reference to the grade of recommendation and level of evidence. This consensus paper focuses on early-stage disease.

Abstract
Current standard therapy for advanced or metastatic non-small cell lung cancer (NSCLC) includes chemotherapy, which is often associated with limited efficacy and toxicity. Thus, there is an unmet need for novel anticancer agents that are both effective and well tolerated in patients with NSCLC. Gefitinib (Iressa) is an orally active epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor in advanced clinical development, and the first agent of its kind to receive approval. Extensive evidence indicates that gefitinib provides significant antitumor activity in previously treated advanced NSCLC, along with fast symptom improvement. This orally administered agent is generally well tolerated. Gefitinib has also shown promising efficacy in other solid tumors that rely on EGFR-related mechanisms for growth and survival. This article reviews the profile of gefitinib and the evidence supporting its use in the treatment of NSCLC.

Abstract
ABSTRACT: Modulation of a patient’s immune system so that it acts against lung cancer cells has not been successful in the past decades. Advances in our understanding of the immune response to tumors resulted in the development of different kinds of novel immunotherapeutic agents. This has resulted in the development of two major approaches. First, antigen-specific immunotherapy or cancer vaccination, with the MAGE-A3 vaccine in resected early-stage non-small-cell lung cancer (NSCLC), the L-BLP25 vaccine in locally advanced NSCLC after chemoradiotherapy and belagenpumatucel-L and the TG4010 vaccine in advanced-stage NSCLC. Second, non-antigen-specific immunotherapy or cancer immunomodulation is reviewed, including how monoclonal antibodies modulate the interaction between antigen-presenting cells, T-lymphocytes and tumor cells (e.g., antibodies against CTLA-4, or against PD-1 receptor or its ligands). Recent Phase II trials with these treatments have shown promising results of efficacy and tolerability, which has led to testing in several large Phase III trials. Some of these are fully recruited, while others are still ongoing, and important results are be expected in the near future.

Meta-analysis of individual patient data from randomized trials of chemotherapy plus cetuximab as first-line treatment for advanced non-small cell lung cancer. Lung Cancer 2013; 83:211-8.

Abstract
OBJECTIVES Four randomized phase II/III trials investigated the addition of cetuximab to platinum-based, first-line chemotherapy in patients with advanced non-small cell lung cancer (NSCLC). A meta-analysis was performed to examine the benefit/risk ratio for the addition of cetuximab to chemotherapy. MATERIALS AND METHODS The meta-analysis included individual patient efficacy data from 2018 patients and individual patient safety data from 1970 patients comprising respectively the combined intention-to-treat and safety populations of the four trials. The effect of adding cetuximab to chemotherapy was measured by hazard ratios (HRs) obtained using a Cox proportional hazards model and odds ratios calculated by logistic regression. Survival rates at 1 year were calculated. All applied models were stratified by trial. Tests on heterogeneity of treatment effects across the trials and sensitivity analyses were performed for all endpoints. RESULTS The meta-analysis demonstrated that the addition of cetuximab to chemotherapy significantly improved overall survival (HR 0.88, p=0.009, median 10.3 vs 9.4 months), progression-free survival (HR 0.90, p=0.045, median 4.7 vs 4.5 months) and response (odds ratio 1.46, p<0.001, overall response rate 32.2% vs 24.4%) compared with chemotherapy alone. The safety profile of chemotherapy plus cetuximab in the meta-analysis population was confirmed as manageable. Neither trials nor patient subgroups defined by key baseline characteristics showed significant heterogeneity for any endpoint. CONCLUSION The addition of cetuximab to platinum-based, first-line chemotherapy for advanced NSCLC significantly improved outcome for all efficacy endpoints with an acceptable safety profile, indicating a favorable benefit/risk ratio.

Abstract
BACKGROUND Pulmonary function may decline after induction chemotherapy and predict perioperative complications in non-small cell lung cancer (NSCLC). The influence of adjuvant chemotherapy is largely indeterminate. OBJECTIVE To assess whether adjuvant chemotherapy alters pulmonary function and impacts on treatment-related adverse events. METHODS In a trial on adjuvant chemotherapy (the TREAT trial), 132 patients with R0-resected NSCLC were randomised to 4 cycles of cisplatin-vinorelbine (CVb, n = 65) or cisplatin-pemetrexed (CPx, n = 67). Pulmonary function tests (forced expiratory volume in 1 s, FEV1, forced vital capacity, FVC, total lung capacity, TLC, diffusing capacity for carbon monoxide, DLCO, and blood gas analyses, BGA) were analysed before and 30 days after the last chemotherapy, and changes were calculated (Δ = mean differences). RESULTS Overall, FVC increased significantly (Δ +290 ml, n = 76; p < 0.0001), while TLC did not change (Δ +220 ml, n = 41; p = 0.174). For CPx, FEV1 increased significantly (Δ +150 ml, n = 47; p = 0.0017), but not for CVb (Δ +30 ml, n = 30). DLCO decreased only for CVb (-8%, n = 6) but not for CPx (-0.39%, n = 17; p = 0.58). BGA did not change (p = 0.99). In a Cox regression analysis, baseline pulmonary function did not influence treatment failure. CONCLUSIONS Adjuvant chemotherapy seems not to result in a decrease of pulmonary function parameters. A significant FVC increase was probably due to ongoing postoperative improvement. Decline of DLCO was noted with CVb but not with CPx. Pulmonary function does not impact on treatment failure.

Modern post-operative radiotherapy for stage III non-small cell lung cancer may improve local control and survival: a meta-analysis. Radiother Oncol 2013; 110:3-8.

Abstract
BACKGROUND We hypothesized that modern postoperative radiotherapy (PORT) could decrease local recurrence (LR) and improve overall survival (OS) in patients with stage IIIA-N2 non-small-cell lung cancer (NSCLC). METHODS To investigate the effect of modern PORT on LR and OS, we identified published phase III trials for PORT and stratified them according to use or non-use of linear accelerators. Non-individual patient data were used to model the potential benefit of modern PORT in stage IIIA-N2 NSCLC treated with induction chemotherapy and resection. RESULTS Of the PORT phase III studies, eleven trials (2387 patients) were included for OS analysis and eight (1677 patients) for LR. PORT decreased LR, whether given with cobalt, cobalt and linear accelerators, or with linear accelerators only. An increase in OS was only seen when PORT was given with linear accelerators, along with the most significant effect on LR (relative risk for LR and OS 0.31 (p=0.01) and 0.76 (p=0.02) for PORT vs. controls, respectively). Four trials (357 patients) were suitable to assess LR rates in stage III NSCLC treated with surgery, in most cases after induction chemotherapy. LR as first relapse was 30% (105/357) after 5 years. In the modeling part, PORT with linear accelerators was estimated to reduce LR rates to 10% as first relapse and to increase the absolute 5-year OS by 13%. CONCLUSIONS This modeling study generates the hypothesis that modern PORT may increase both LR and OS in stage IIIA-N2 NSCLC even in patients being treated with induction chemotherapy and surgery.

Abstract
BACKGROUND Radiation-induced lung damage (RILD) is an important problem. Although physical parameters such as the mean lung dose are used in clinical practice, they are not suited for individualised radiotherapy. Objective, quantitative measurements of RILD on a continuous instead of on an ordinal, semi-quantitative, semi-subjective scale, are needed. METHODS Hounsfield unit (HU) changes before versus three months post-radiotherapy were correlated per voxel with the radiotherapy dose in 95 lung cancer patients. Deformable registration was used to register pre- and post-CT scans and the density increase was quantified for various dose bins. The dose-response curve for increased HU was quantified using the slope of a linear regression (HU/Gy). The end-point for the toxicity analysis was dyspnoea ≥ grade 2. RESULTS Radiation dose was linearly correlated with the change in HU (mean R(2) = 0.74 ± 0.28). No differences in HU/Gy between groups treated with stereotactic radiotherapy, conventional radiotherapy alone, sequential or concurrent chemo- radiotherapy were observed. In the whole patient group, 33/95 (34.7%) had dyspnoea ≥ G2. Of the 48 patients with a HU/Gy below the median, 16 (33.3%) developed dyspnoea ≥ G2, while in the 47 patients with a HU/Gy above the median, 17 (36.1%) had dyspnoea ≥ G2 (not significant). Individual patients showed a nearly 21-fold difference in radiosensitivity, with HU/Gy ranging from 0 to 10 HU/Gy. CONCLUSIONS HU changes identify objectively the whole range of individual radiosensitivity on a continuous, quantitative scale. CT density changes may allow more robust and accurate radiogenomics studies.

Abstract
Purpose To detect a pretreatment gene expression signature (GS) predictive of response to MAGE-A3 immunotherapeutic in patients with metastatic melanoma and to investigate its applicability in a different cancer setting (adjuvant therapy of resected early-stage non–small-cell lung cancer [NSCLC]). Patients and Methods Patients were participants in two phase II studies of the recombinant MAGE-A3 antigen combined with an immunostimulant (AS15 or AS02B). mRNA from melanoma biopsies was analyzed by microarray analysis and quantitative polymerase chain reaction. These results were used to identify and cross-validate the GS, which was then applied to the NSCLC data. Results In the patients with melanoma, 84 genes were identified whose expression was potentially associated with clinical benefit. This effect was strongest when the immunostimulant AS15 was included in the immunotherapy (hazard ratio [HR] for overall survival, 0.37; 95% CI, 0.13 to 1.05; P = .06) and was less strong with the other immunostimulant AS02B (HR, 0.84; 95% CI, 0.36 to 1.97; P = .70). The same GS was then used to predict the outcome for patients with resected NSCLC treated with MAGE-A3 plus AS02B; actively treated GS-positive patients showed a favorable disease-free interval compared with placebo-treated GS-positive patients (HR, 0.42; 95% CI, 0.17 to 1.03; P = .06), whereas among GS-negative patients, no such difference was found (HR, 1.17; 95% CI, 0.59 to 2.31; P = .65). The genes identified were mainly immune related, involving interferon gamma pathways and specific chemokines, suggesting that their pretreatment expression influences the tumor's immune microenvironment and the patient's clinical response. Conclusion An 84-gene GS associated with clinical response for MAGE-A3 immunotherapeutic was identified in metastatic melanoma and confirmed in resected NSCLC.

Abstract
PURPOSE The MAGE-A3 protein is expressed in approximately 35% of patients with resectable non-small-cell lung cancer (NSCLC). Several immunization approaches against the MAGE-A3 antigen have shown few, but often long-lasting, clinical responses in patients with metastatic melanoma. PATIENTS AND METHODS A double-blind, randomized, placebo-controlled phase II study was performed assessing clinical activity, immunologic response, and safety following immunization with recombinant MAGE-A3 protein combined with an immunostimulant (13 doses over 27 months) in completely resected MAGE-A3-positive stage IB to II NSCLC. The primary end point was disease-free interval (DFI). RESULTS Patients were randomly assigned to either MAGE-A3 immunotherapeutic (n = 122) or placebo (n = 60). After a median postresection period of 44 months, recurrence was observed in 35% of patients in the MAGE-A3 arm and 43% in the placebo arm. No statistically significant improvement in DFI (hazard ratio [HR], 0.75, 95% CI, 0.46 to 1.23; two-sided P = .254), disease-free survival (DFS; HR, 0.76; 95% CI, 0.48 to 1.21; P = .248), or overall survival (HR, 0.81; 95% CI, 0.47 to 1.40; P = .454) was observed. Corresponding analysis after a median of 70 months of follow-up revealed a similar trend for DFI and DFS. All patients receiving the active treatment showed a humoral immune response to the MAGE-A3 antigen, although no correlation was observed with outcome. No significant toxicity was observed. CONCLUSION In this early development study with a limited number of patients, postoperative MAGE-A3 immunization proved to be feasible with minimal toxicity. These results are being investigated further in a large phase III study.

Abstract
8063 Background: EGFR mutation+ (M+) NSCLC pts have an improved response to EGFR TKIs vs non-M+ pts. Data on EGFR FISH+ (gene amplified) and HER2 M+ pts are, however, limited. Afatinib is an irreversible ErbB Family Blocker with efficacy in Ph II/III trials in EGFR M+ NSCLC. This exploratory, open-label trial assessed afatinib in 3 genotypically and demographically defined NSCLC groups. Methods: Never/ex-smokers with stage IIIB/IV lung adenocarcinoma with EGFR M+ tumors who had failed prior EGFR TKIs, HER2 M+ tumors independent of prior therapy, or EGFR FISH+ tumors who received ≤3 prior chemotherapies were enrolled. Afatinib 50 mg qd was administered until disease progression or intolerable adverse events. Tumor assessments (RECIST 1.0) were performed every 8 wks. Pts who progressed on afatinib but experienced clinical benefit could continue treatment with afatinib 40 mg qd + paclitaxel 80 mg/m² qw on days 1, 8 and 15 every 28-day cycle. Primary endpoint: Confirmed objective response. Results: 41 pts were treated: 63% female; median age 63 yrs; 68% never smokers; 32% ex-smokers. 33 pts received afatinib monotherapy only; 8 pts received afatinib followed by afatinib/paclitaxel combination therapy. 78% (n=32) of pts were EGFR M+, 5% (n=2) were EGFR FISH+ and 17% (n=7) were HER2 M+. For afatinib monotherapy, 1 confirmed partial response (PR) was observed (EGFR FISH+), stable disease (SD) was seen in 5/7 HER2 M+, 2/2 EGFR FISH+ and 17/32 EGFR M+ pts, and overall disease control (DC) rate was 59% (n=24); mean duration of DC was 26 wks.Median PFS was 16 wks (17 wks in HER2 M+ pts). Of 8 afatinib/paclitaxel-treated pts, 1 had a confirmed PR and 2 had SD; median PFS was 7 wks. Most frequently reported drug-related AEs in afatinib monotherapy pts were diarrhea (n=39; grade ≥3 n=13), rash/acne (n=33; grade ≥3 n=4) and stomatitis (n=19; grade ≥3 n=2). In the combination arm these were diarrhea (n=4; grade ≥3 n=1) and nausea (n=3; grade ≥3 n=0). Conclusions: Efficacy of afatinib in EGFR M+ NSCLC pts has been established in previous trials. Novel activity of afatinib in HER2 M+ and EGFR FISH+ NSCLC pts has been demonstrated here, with a manageable safety profile of afatinib in the overall population. Clinical trial information: NCT00730925.

Abstract
The greatest news of the past year in this field was the first large-scale early detection trial that could prove a 20% reduction in lung cancer-related mortality by screening high-risk individuals with low-dose computed tomography (LDCT). Several expert groups and medical societies have assessed the data and concluded that LDCT screening for lung cancer is, however, not ready for large-scale population-based implementation. Too many open questions remain, such as definition of the at-risk population, timing and intervals of screening, optimal method of acquisition and interpretation of the images, how to handle (false) positive findings, and especially cost-effectiveness in relation to other lung cancer prevention strategies, mainly smoking cessation. Further analyses and several ongoing European trials are eagerly awaited. Much hope also resides in the use of biomarkers, as their use in, e.g., blood or exhaled air may provide more easy-to-use tests to better stratify high-risk populations for screening studies. While exciting research is ongoing in this domain--e.g. with microRNAs--none of the tests has yet reached sufficient validation for clinical use. Early central lung cancers are more difficult to visualise by CT. For these patients, standard bronchoscopy, complemented by autofluoresence endoscopy, has been studied in different screening and follow-up settings.

Abstract
BACKGROUND Prior to the approval of the first erythropoiesis-stimulating agent (ESA) in the early 1990s, red blood cell transfusions were the primary means of treating severe chemotherapy-induced anemia (CIA), with little recourse for those with more mild forms of the condition. The introduction of the ESAs allowed treatment of mild-to-moderate CIA in patients with cancer. It has been a decade since darbepoetin alfa (DA), a second-generation ESA with a longer half-life, became available to patients with CIA. OBJECTIVE AND METHODS We present a review of studies on DA in CIA, from its development through to the present day. Medline was searched for randomized clinical trials on DA. Additional trials and meta-analyses on ESAs were incorporated into this review when relevant. RESULTS The first publications on DA generally focused on optimal dosing, efficacy and tolerability. In these, it was shown that DA is an effective and well tolerated treatment option to achieve hematopoietic response, regardless of dosing interval. Subsequently, the focus shifted towards meta-analyses on survival data of all ESAs. These reported conflicting results regarding mortality and/or disease progression. However, guidelines for ESA use were updated and, when followed, these make ESAs a well tolerated and effective tool for managing CIA. CONCLUSIONS As the past decade has broadened our knowledge on the benefits and risks of CIA management, continued high-quality studies will help to optimize treatment with ESAs in order to maximize quality of life for these patients. The limitation of a literature review of this nature is the complete reliance on previously published research and the availability of these studies using the methodology outlined above.
