Abstract
Introduction: Data on the clinical outcomes of patients receiving adjuvant chemotherapy for surgically resected high-grade pulmonary neuroendocrine carcinoma (HGNEC) (large-cell neuroendocrine carcinoma and small-cell lung cancer) are limited. This study aimed to evaluate the prognostic significance of adjuvant chemotherapy in patients with HGNEC.
Methods: We retrospectively analyzed patients with surgically resected HGNEC at five institutions in Japan between January 2006 and May 2016.
Results: A total of 143 patients were enrolled. Among them, 65 received adjuvant chemotherapy. Four patients who participated in clinical trials were excluded; the remaining 61 patients were included in the study. Fifty-six patients received adjuvant small-cell lung cancer-based chemotherapy. Twenty-five of 29 patients who relapsed after postoperative adjuvant chemotherapy received chemotherapy. The most commonly administered chemotherapy agent was amrubicin. The 3-year relapse-free and overall survival rates were 55.2% and 66.8%, respectively. The median relapse-free and overall survival times for the 25 patients who received chemotherapy after relapse were 12.9 and 27.5 months, respectively. Among them, 22 relapsed within 2 years. Patients who received platinum-doublet chemotherapy after relapse tended to have better time to progression disease and overall survival than those who received single-agent chemotherapy.
Conclusions: Most patients with HGNEC received small-cell lung cancer-based regimens as postoperative adjuvant chemotherapy. Those who relapsed after adjuvant chemotherapy were mainly treated with amrubicin. Our findings suggest that platinum-doublet chemotherapy tends to improve the time to progression disease and overall survival in patients who relapse after postoperative adjuvant chemotherapy.
期刊介绍:
This journal publishes original research articles and state-of-the-art reviews on all aspects of antimicrobial and antitumor chemotherapy. The results of experimental and clinical investigations into the microbiological and pharmacologic properties of antibacterial, antiviral and antitumor compounds are major topics of publication. Papers selected for the journal offer data concerning the efficacy, toxicology, and interactions of new drugs in single or combined applications. Studies designed to determine the pharmacokinetic and pharmacodynamics properties of similar preparations and comparing their efficacy are also included. Special emphasis is given to the development of drug-resistance, an increasing problem worldwide.
