The Optimal Treatment Modality in Patients with T4N2M0 Non-Small Cell Lung Cancer: The Best Choice May Be Definitive Chemoradiotherapy Followed by Consolidation Chemotherapy

Short-Term Efficacy of Different First-Line Chemotherapy Regimens for Advanced Non-Small Cell Lung Cancer: A Network Meta-Analysis

This study intends to compare short‐term efficacy of 12 chemotherapy regimens in treatment of advanced non‐small cell lung cancer (NSCLC) by a network meta‐analysis (NMA). PubMed, Cochrane Library, and Embase were searched from the inception of each database to June 2018. Randomized controlled trials (RCTs) of the 12 chemotherapy regimens for advanced NSCLC were included. Direct and indirect evidence were combined by NMA to evaluate the odds ratio and the surface under the cumulative ranking curves (SUCRA) of the 12 chemotherapy regimens. Nineteen RCTs that met our inclusion criteria were collected in this study. For partial response (PR), gemcitabine exhibited relatively poor efficacy compared with cisplatin + gemcitabine, carboplatin + gemcitabine, carboplatin + paclitaxel, paclitaxel + gemcitabine, and cisplatin + gemcitabine + vinorelbine. For overall response rate (ORR), gemcitabine had poorer efficacy than cisplatin + gemcitabine and paclitaxel + gemcitabine. For disease control rate (DCR), compared with carboplatin + gemcitabine and gemcitabine, paclitaxel + gemcitabine had a better efficacy. Gemcitabine had the lowest SUCRA values in terms of complete response, PR, ORR, stable disease, and DCR; whereas paclitaxel + gemcitabine ranked the highest in ORR, progressive disease, and DCR. The cluster analysis revealed that cisplatin + gemcitabine, paclitaxel + gemcitabine, and cisplatin + gemcitabine + vinorelbine had better short‐term efficacy for advanced NSCLC. Collectively, short‐term efficacy of multidrug combination chemotherapy regimens was superior to that of single‐drug chemotherapy regimens for advanced NSCLC. Cisplatin + gemcitabine, paclitaxel + gemcitabine, and cisplatin + gemcitabine + vinorelbine may have particularly prominent short‐term efficacy for advanced NSCLC.

Oral vinorelbine plus cisplatin with concomitant radiotherapy as induction therapy for stage III non-small cell lung cancer: Results of a single-arm prospective cohort study

Background

Concurrent chemoradiotherapy (CCRT) is an optimal recommended treatment for stage III non‐small cell lung cancer (NSCLC). Herein, we aimed to investigate the efficacy and safety of oral vinorelbine plus cisplatin with concomitant radiotherapy for stage III NSCLC.

Methods

This prospective, open‐label, single‐arm, observational cohort study was performed between January 2010 and September 2016. Patients were treated with two cycles of chemotherapy with 60 mg/m² intravenous cisplatin on day 1 and 50 mg/m² oral vinorelbine on days 1, 8, and 15; radiotherapy was administered concurrently from day 1 when chemotherapy was initiated. A total dose of 66–70 Gy radiotherapy was delivered in daily fractions of 2 Gy for 6.5–7 consecutive weeks. The tumor response was assessed after completing concomitant treatment.

Results

A total of 58 patients were enrolled and analyzed; 31 patients had stage IIIA NSCLC and 27 had stage IIIB NSCLC. After induction CCRT, 31 patients achieved an objective response (complete response in one and partial response in 30; the response rate was 53.4%). The median progression‐free survival was 6.73 months (95% confidence interval [CI], 5.42–7.91), duration of response was 12.30 months (95% CI, 5.59–19.01), and overall survival was 24.83 months (95% CI, 19.26–30.21). No treatment‐related mortality was observed, and neutropenia was the most common grade 3 and 4 treatment‐related toxicity (11 patients; 18.9%).

Conclusions

CCRT with the weekly regimen of oral vinorelbine plus triweekly cisplatin was effective and safe for stage III NSCLC.
