There is little evidence on treatment strategy for postoperative locoregional relapsed nonesmall-cell lung cancer. Seventy-four consecutive patients with nonesmall-cell lung cancer with postoperative locoregional recurrences who received chemoradiotherapy (CRT) or radiotherapy at our institute were analyzed. Multivariate analysis identified CRT as a significant survival factor. CRT showed favorable survival outcomes with acceptable feasibility of both CRT and radiotherapy.
Background: The optimal treatment strategy for locoregional recurrences developing after surgical resection in patients with nonesmall-cell lung cancer (NSCLC) is yet to be clearly established. Patients and Methods: To investigate the efficacy and safety of radiotherapy (RT) and chemoradiotherapy (CRT), we reviewed the consecutive data of patients with NSCLC with postoperative locoregional recurrences treated at the National Cancer Center Hospital between January 2000 and April 2010. Results: We reviewed the data of 74 patients (including 56 who received RT alone and 18 who received CRT) according to our study criteria. The median age was lower and the N factor at the recurrence site was higher in the CRT group compared with the RT group. Most patients received 60 Gy/30 Fr RT in both groups. The 2-year progression-free survival (PFS) rate, median PFS, and overall survival (OS) were 44.4%, 19.0 months (95% confidence interval [CI], 0-41.9 months), and 79.6 months (95% CI, 8.2-151.0 months), respectively, in the CRT group, although those were 25.0%, 10.6 months (95% CI, 8.7-12.9 months), and 33.1 months (95% CI, 17.9-48.3 months), respectively, in the RT group. The adverse event profile was acceptable, with no treatment-related death in either group. Multivariate analysis identified CRT as being significantly associated with a longer PFS and OS. Conclusion: CRT tended to yield better results than RT in terms of the survival outcomes, with acceptable safety profiles of both. We consider that a randomized study comparing RT and CRT is warranted to identify the optimal treatment strategy for patients with NSCLC with postoperative locoregional recurrences.
