BACKGROUND Ramucirumab is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. We aimed to assess efficacy and safety of treatment with docetaxel plus ramucirumab or placebo as second-line treatment for patients with stage IV non-small-cell-lung cancer (NSCLC) after platinum-based therapy. METHODS In this multicentre, double-blind, randomised phase 3 trial (REVEL), we enrolled patients with squamous or non-squamous NSCLC who had progressed during or after a first-line platinum-based chemotherapy regimen. Patients were randomly allocated (1:1) with a centralised, interactive voice-response system (stratified by sex, region, performance status, and previous maintenance therapy [yes vs no]) to receive docetaxel 75 mg/m(2) and either ramucirumab (10 mg/kg) or placebo on day 1 of a 21 day cycle until disease progression, unacceptable toxicity, withdrawal, or death. The primary endpoint was overall survival in all patients allocated to treatment. We assessed adverse events according to treatment received. This study is registered with ClinicalTrials.gov, number NCT01168973. FINDINGS Between Dec 3, 2010, and Jan 24, 2013, we screened 1825 patients, of whom 1253 patients were randomly allocated to treatment. Median overall survival was 10·5 months (IQR 5·1-21·2) for 628 patients allocated ramucirumab plus docetaxel and 9·1 months (4·2-18·0) for 625 patients who received placebo plus docetaxel (hazard ratio 0·86, 95% CI 0·75-0·98; p=0·023). Median progression-free survival was 4·5 months (IQR 2·3-8·3) for the ramucirumab group compared with 3·0 months (1·4-6·9) for the control group (0·76, 0·68-0·86; p<0·0001). We noted treatment-emergent adverse events in 613 (98%) of 627 patients in the ramucirumab safety population and 594 (95%) of 618 patients in the control safety population. The most common grade 3 or worse adverse events were neutropenia (306 patients [49%] in the ramucirumab group vs 246 [40%] in the control group), febrile neutropenia (100 [16%] vs 62 [10%]), fatigue (88 [14%] vs 65 [10%]), leucopenia (86 [14%] vs 77 [12%]), and hypertension (35 [6%] vs 13 [2%]). The numbers of deaths from adverse events (31 [5%] vs 35 [6%]) and grade 3 or worse pulmonary haemorrhage (eight [1%] vs eight [1%]) did not differ between groups. Toxicities were manageable with appropriate dose reductions and supportive care. INTERPRETATION Ramucirumab plus docetaxel improves survival as second-line treatment of patients with stage IV NSCLC.

Recent strategies targeting the interaction of the programmed cell death ligand-1 (PD-L1, B7-H1, CD274) with its receptor, PD-1, resulted in promising activity in early phase clinical trials. In this study, we used various antibodies and in situ mRNA hybridization to measure PD-L1 in non-small cell lung cancer (NSCLC) using a quantitative fluorescence (QIF) approach to determine the frequency of expression and prognostic value in two independent populations. A control tissue microarray (TMA) was constructed using PD-L1-transfected cells, normal human placenta and known PD-L1-positive NSCLC cases. Only one of four antibodies against PD-L1 (5H1) validated for specificity on this TMA. In situ PD-L1 mRNA using the RNAscope method was similarly validated. Two cohorts of NSCLC cases in TMAs including 340 cases from hospitals in Greece and 204 cases from Yale University were assessed. Tumors showed PD-L1 protein expression in 36% (Greek) and 25% (Yale) of the cases. PD-L1 expression was significantly associated with tumor-infiltrating lymphocytes in both cohorts. Patients with PD-L1 (both protein and mRNA) expression above the detection threshold showed statistically significant better outcome in both series (log-rank P=0.036 and P=0.027). Multivariate analysis showed that PD-L1 expression was significantly associated with better outcome independent of histology. Measurement of PD-L1 requires specific conditions and some commercial antibodies show lack of specificity. Expression of PD-L1 protein or mRNA is associated with better outcome. Further studies are required to determine the value of this marker in prognosis and prediction of response to treatments targeting this pathway.

BACKGROUND There is a major unmet need for effective treatments in patients with squamous cell carcinoma of the lung. LUX-Lung 8 compared afatinib (an irreversible ErbB family blocker) with erlotinib (a reversible EGFR tyrosine kinase inhibitor), as second-line treatment for patients with advanced squamous cell carcinoma of the lung. METHODS We did this open-label, phase 3 randomised controlled trial at 183 cancer centres in 23 countries worldwide. We enrolled adults with stage IIIB or IV squamous cell carcinoma of the lung who had progressed after at least four cycles of platinum-based-chemotherapy. Participants were randomly assigned (1:1) to receive afatinib (40 mg per day) or erlotinib (150 mg per day) until disease progression. The randomisation was done centrally with an interactive voice or web-based response system and stratified by ethnic origin (eastern Asian vs non-eastern Asian). Clinicians and patients were not masked to treatment allocation. The primary endpoint was progression-free survival assessed by independent central review (intention-to-treat population). The key secondary endpoint was overall survival. This trial is registered with ClinicalTrials.gov, NCT01523587. FINDINGS 795 eligible patients were randomly assigned (398 to afatinib, 397 to erlotinib). Median follow-up at the time of the primary analysis of progression-free survival was 6·7 months (IQR 3·1-10·2), at which point enrolment was not complete. Progression free-survival at the primary analysis was significantly longer with afatinib than with erlotinib (median 2·4 months [95% CI 1·9-2·9] vs 1·9 months [1·9-2·2]; hazard ratio [HR] 0·82 [95% CI 0·68-1·00], p=0·0427). At the time of the primary analysis of overall survival (median follow-up 18·4 months [IQR 13·8-22·4]), overall survival was significantly greater in the afatinib group than in the erloinib group (median 7·9 months [95% CI 7·2-8·7] vs 6·8 months [5·9-7·8]; HR 0·81 [95% CI 0·69-0·95], p=0·0077), as were progression-free survival (median 2·6 months [95% CI 2·0-2·9] vs 1·9 months [1·9-2·1]; HR 0·81 [95% CI 0·69-0·96], p=0·0103) and disease control (201 [51%] of 398 patients vs 157 [40%] of 397; p=0·0020). The proportion of patients with an objective response did not differ significantly between groups (22 [6%] vs 11 [3%]; p=0·0551). Tumour shrinkage occurred in 103 (26%) of 398 patients versus 90 (23%) of 397 patients. Adverse event profiles were similar in each group: 224 (57%) of 392 patients in the afatinib group versus 227 (57%) of 395 in the erlotinib group had grade 3 or higher adverse events. We recorded higher incidences of treatment-related grade 3 diarrhoea with afatinib (39 [10%] vs nine [2%]), of grade 3 stomatitis with afatinib (16 [4%] vs none), and of grade 3 rash or acne with erlotinib (23 [6%] vs 41 [10%]). INTERPRETATION The significant improvements in progression-free survival and overall survival with afatinib compared with erlotinib, along with a manageable safety profile and the convenience of oral administration suggest that afatinib could be an additional option for the treatment of patients with squamous cell carcinoma of the lung.

ObjectiveTo evaluate the clinical usefulness of serum vascular endothelial growth factor (VEGF) levels in gastric cancer patients. Summary Background DataVascular endothelial growth factor plays an important role in the formation of new blood vessels involved in the growth and metastatic spread of solid tumors, but there is limited information regarding the clinical significance of serum VEGF levels in cancer patients. MethodsSerum VEGF concentrations were measured by an enzyme linked immunosorbent assay in 61 healthy controls and in 58 gastric cancer patients before surgery, and then again at 7 and 30 days after surgery. The association between preoperative serum VEGF levels, clinicopathological features and patient survival, and their changes following surgery were evaluated. ResultsSerum VEGF levels in gastric cancer patients were significantly higher than those in controls. There was a significant association between serum VEGF levels and disease stage, as well as invasion depth of the tumor and the presence of distant metastases. Serum VEGF levels decreased significantly after radical resection of the primary tumor and increased in patients with unresectable tumors. Multivariate regression analysis showed that serum VEGF level is an independent prognostic factor for survival. ConclusionsSerum VEGF levels in gastric patients are significantly higher compared with normal controls and correlate with local tumor extent, disease stage, and the presence of distant metastases. Preoperative serum VEGF concentration decreases significantly after radical resection of the primary tumor and is an independent prognostic factor for patient survival suggesting that determination of serum VEGF levels may be clinically useful.

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.

The serum concentrations of the cell adhesion molecules E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) were investigated in 63 patients with colorectal cancer and in 51 controls by an enzyme-linked immunosorbent assay (ELISA). Their relationship to clinicopathological variables and patient survival and changes in their levels after surgery were examined. Colorectal cancer patients showed significantly higher serum levels of E-selectin, ICAM-1 and VCAM-1 compared with healthy controls. There was a significant association between the serum levels of these molecules, disease stage and the presence of both lymph node and distant metastases. Both ICAM-1 and VCAM-1 levels correlated with serum E-selectin and carcinoembryonic antigen (CEA) levels. Serum levels of all three molecules decreased significantly after radical resection of the tumour. Elevated pre-operative E-selectin, ICAM-1 and VCAM-1 levels were significant prognostic factors, although not independent of stage, for patient survival. These findings suggest that serum concentrations of E-selectin, ICAM-1 and VCAM-1 may reflect tumour progression and metastasis. Since these markers are linked to CEA levels, it is uncertain whether their measurement will prove cost-effective in colorectal cancer management.

PURPOSE To compare the overall survival (OS) of patients with advanced non-small-cell lung cancer (NSCLC) treated with docetaxel plus cisplatin (DC) or docetaxel (D) alone. PATIENTS AND METHODS Chemotherapy-naïve patients with advanced/metastatic NSCLC were randomly assigned to receive either DC (n = 167; docetaxel 100 mg/m(2) on day 1, cisplatin 80 mg/m(2) on day 2, and recombinant human granulocyte colony-stimulating factor (rhG-CSF) 150 microg/m(2)/d on days 3 to 9) or D (n = 152; 100 mg/m(2) on day 1 without rhG-CSF) every 3 weeks. RESULTS The overall response rates were 36.5% for DC (three complete responses and 58 partial responses) and 21.7% for D (one complete response and 32 partial responses; P =.004). The median OS was 10.5 months (range, 0.5 to 41 months) and 8.0 months (range, 0.5 to 41 months) for DC and D, respectively (P =.200). The 1- and 2-year survival rates were 44% and 19% for DC and 43% and 15% for D, respectively. Median times to tumor progression were 4.0 and 2.5 months for DC and D, respectively (P =.580). Grade 2/3 anemia was significantly higher with DC than with D (33% v 16%; P =.0001). Fifteen (9%) DC and 12 (8%) D patients developed febrile neutropenia. Grade 3/4 nausea/vomiting (P =.0001), diarrhea (P =.007), neurotoxicity (P =.017), and nephroroxicity (P =.006) were significantly more common with DC than with D. There were five treatment-related deaths in the DC group and one in the D (P =.098). CONCLUSION DC regimen resulted in a higher response rate but without improvement in median time to tumor progression or OS compared with D. D could be a reasonable front-line chemotherapy for patients who cannot tolerate cisplatin.
