re detected in 48% (25 of 52 tested) of adenocarcinomas and 55.55% (5 of 9 tested) of young, nonsmoker, female squamous cell carcinoma patients.
This study highlights that the adenocarcinoma incidence is surpassing squamous cell carcinoma in Indian lung cancer patients also, as observed in Western population. Mean age at diagnosis is about one decade earlier than in the Western population. Driver mutations are more common in India than in the West as also reported in other Asian studies.

The benefits of second-line chemotherapy on the overall survival (OS) of small-cell lung cancer (SCLC) patients might be confounded by subsequent therapies. In this study, we aimed to determine the influence of progression-free survival (PFS) and postprogression survival (PPS) on OS after second-line chemotherapy in patients with refractory SCLC treated with amrubicin monotherapy.
We analyzed the data of 35 patients with refractory SCLC who were treated with amrubicin monotherapy as second-line chemotherapy between July 2005 and December 2015. The correlations of PFS and PPS with OS were statistically analyzed at the individual level using Spearman's rank correlation and linear regression analyses.
The correlation between PPS and OS was strong (r = 0.88, P < 0.05, R
= 0.87), while that between PFS and OS was weak (r = 0.60, P < 0.05, R
= 0.15). The number of regimens administered after disease progression postsecond-line chemotherapy was significantly associated with PPS (P = 0.003).
OS is more strongly linked to PPS than to PFS in refractory SCLC patients who undergo amrubicin monotherapy as a second-line treatment. These results suggest that treatments administered after second-line chemotherapy affect the OS of refractory SCLC patients treated with amrubicin monotherapy.

To assess the survival outcomes and prognostic factors of young (≤45 years) Stage IIIB nonsmall cell lung cancer (NSCLC) patients treated with definitive concurrent chemoradiotherapy (C-CRT).
Medical records of 145 Stage IIIB NSCLC patients (≤45 years) who received 60-66 Gy thoracic radiotherapy and concurrent 1-3 cycles of cisplatin-based doublet chemotherapy were retrospectively evaluated. The primary endpoint was overall survival (OS), while locoregional progression-free survival (LRPFS), progression-free survival (PFS), and evaluation of potential prognostic factors constituted the secondary endpoints.
At median 21.6 months (range 7.3-62.5) of follow-up, the median and 4-year survival estimates were 24.8 months and 24.2% for OS, 15.7 months and 18.9%, for LRPFS and 12.0 months and 11.2% for PFS, respectively. On univariate analyses, among all factors, the smaller tumor size (≤7.0 cm; P = 0.03), lower T-stage (T1-T2; P = 0.02), lower N-stage (N2; P = 0.01), absence of anemia before C-CRT (hemoglobin WL levels suggests a noteworthy prognostic role for these two latter variables in the stratification of such patients.
In extensive-disease-small cell lung cancer (ED-SCLC), the median survival is 8-10 months and 2-year survival is <5%. Primary tumor progression occurs in 90% of patients approximately within 1 year. The role of consolidative thoracic radiotherapy (C-TRT) for the postchemotherapy residue with the aim of improving local control (LC) and survival is currently of great interest. The objective of this study is to determine the effectiveness of C-TRT on LC, progression-free survival (PFS), and overall survival (OS) in ED-SCLC.
Medical records of patients diagnosed as SCLC between January 2010 and December 2015 were evaluated retrospectively. Patients who received C-TRT were identified. Pre- and post-chemotherapy radiological evaluations, radiotherapy schedules, relapse patterns, toxicity incidence, LC, PFS, and OS were analyzed.
Among 552 SCLC patients, 26 ED-SCLC patients who underwent C-TRT were analyzed. Median follow-up was 7.5 months (range, 6.5-8.5 months). Nearly 50% of the patients had >4 metastatic lesions. Restaging was performed mostly by positron emission tomography/computed tomography and cranial magnetic resonance imaging. All patients had complete or near-complete response distantly. C-TRT was 10 × 300 cGy (n = 1), 23 × 200 cGy (n = 2), 25 × 200 cGy (n = 7), 30 × 200 cGy (n = 12), and 33 × 200 cGy (n = 4). There was no toxicity ≥ Grade 3. LC rate was 77%; there was no isolated local relapse. TVB-2640 PFS was 3 months. Median survival was 13 months. The 1- and 2-year OS rates were 62% and 8%, respectively.
In ED-SCLC patients, C-TRT may prevent isolated local recurrence and may improve 1-year survival. This survival improvement might be the reflection of high intrathoracic control achieved in 77% of patients.

The objective of the study was to evaluate the clinical efficacy of kanglaite (KLT) injection combined with gefitinib versus gefitinib alone in the treatment of nonsmall cell lung cancer (NSCLC).
The randomized controlled trials involving NSCLC treatment with KLT injection combined with gefitinib versus gefitinib alone were searched on seven medical databases up to October 2016. Two reviewers independently assessed the methodological quality of the included studies. The RevMan 5.3 software was employed for data analysis.
Seven randomized trials involving 554 patients met our criteria. Compared with gefitinib alone, KLT injection combined with gefitinib showed significant effects in increasing objective response rate (relative risk [RR] =1.38; 95% confidence interval [CI], 1.09-1.75), improving the performance status (RR = 1.80; 95% CI 1.34-2.42), raising the percentages of CD4
cells (weighted mean difference [WMD] = 4.45; 95% CI 2.61-6.28), natural killer cells (WMD = 4.43; 95% CI 3.85-5.01), and ratio of CD4
/CD8
(WMD = 0.
