Purpose:
Surgery is controversial in limited-stage small-cell lung cancer (LS-SCLC) (except for T1-2, N0M0). This study aimed to analyze the survival of LS-SCLC patients with proximal lobe (N1) lymph node metastases after surgery and appropriate postoperative adjuvant treatment.
Patients And Methods:
We reviewed and followed up medical history and survival data of LS-SCLC patients from June 2007 to June 2016, and a total of 68 pathological stage N1 (p-N1) patients who underwent surgical resection and 71 clinical-stage N1 (c-N1) patients who received chemoradiotherapy were included in the final analysis.
Results:
The median follow-up of all the patients was 99.30 months. The median disease-free survival (DFS) of the surgery group was 13.567 months, and the median overall survival (OS) of the surgery and chemoradiotherapy groups were 29.600 months and 21.133 months (P-value < .001), respectively. The 2- and 5-year survival rates of the surgery group were 55.9% and 33.7%, and the 2- and 5-year survival rates of the chemoradiotherapy group were 39.8% and 9.4%, respectively. Meanwhile, postoperative thoracic radiotherapy appeared to be associated with a good prognosis (median OS 36.400 vs. 21.333 months, P-value .048), as did prophylactic cranial irradiation (median OS 50.867 vs. 22.600 months, P-value .007) in the surgery group.
Conclusions:
Surgery may benefit patients with p-N1 SCLC, and in combination with appropriate postoperative adjuvant treatment, surgery may be a new therapeutic modality for SCLC.
