ABSTRACT
Background:
Primary pulmonary lymphoepithelioma-like carcinoma (PLELC) is a rare and unique subtype of non-small cell lung cancer (NSCLC). Studies reporting on salvage treatment for pretreated PLELC are limited. Positive interactions between gemcitabine (GEM) and capecitabine (CAP) have been demonstrated in preclinical studies. In addition, the clinical benefit of the combination has been reported for other malignancies. However, the efficacy and safety of the combination for pretreated PLELC remain unclear. Therefore, we conducted this retrospective study to examine the activity and safety of gemcitabine plus capecitabine (GEM/CAP) combination for previously treated PLELC.Methods:
Patients with PLELC at Sun Yat-sen University Cancer Center who received GEM combined with CAP between May 2013 and January 2021 as the second-line therapy or beyond were retrospectively enrolled. Treatment consisted of intravenous GEM (1,000 mg/m2 on days 1 and 8) and oral CAP (1,000 mg/m2 twice daily on days 1-14) every 3 weeks. Evaluation of response was performed every 2 cycles in accordance with Response Evaluation Criteria in Solid Tumors version 1.1. Safety was assessed in accordance with Common Terminology Criteria for Adverse Events version 5.0. Clinical characteristics were collected from medical records. The survival data were obtained by medical records or telephone. Follow-ups were performed until February 3rd, 2021.Results:
A total of 16 patients were enrolled in this study. There were 5, 4, 4, and 3 patients treated with GEM/CAP combination as the second-, third-, fourth-, and fifth-line settings, respectively. There were 8 patients with partial response (PR) (50.00%), 6 with stable disease (SD) (37.50%), 2 with progressive disease (PD) (12.50%), and none with complete response (CR). The objective response rate and disease control rate (DCR) were 50.00% and 87.50%, respectively. The most common hematological and nonhematological adverse events (AEs) at any grade were neutropenia (31.25%) and hand-foot syndrome (43.75%). At a median follow-up of 29.3 months with 95% confidence interval (CI) of 20.3 to 38.3 months, the median progression-free survival (PFS) was 9.3 months (95% CI 6.5-12.1 months). The median overall survival (OS) was 41.5 months (95% CI 3.1-79.8 months).Conclusions:
This retrospective study demonstrated the potential clinical benefit of GEM in combination with CAP for pretreated PLELC. Future multicenter large-scale, prospective studies are warranted.
