Abstract

Background: The aim of the study was to delineate the treatment modalities and survival outcomes in patients with stage T1-2N0M0 small cell lung cancer (SCLC) who underwent surgery.

Methods: SCLC patients from the Surveillance, Epidemiology, and End Results databases between 2000 and 2020 were investigated. Kaplan-Meier survival analysis was employed to assess cancer-specific survival (CSS) and overall survival (OS) across diverse therapeutic strategies.

Results: The study included 190 patients. Treatment modalities included surgery alone in 65 patients (34.2%), surgery + chemotherapy in 70 patients (36.8%), surgery + radiotherapy in three patients (1.6%), and surgery + chemoradiotherapy in 52 patients (27.4%). The median CSS remained undetermined for the surgery alone group, whereas it was 123 and 113 months for the surgery + chemotherapy and surgery + chemoradiotherapy groups. Median OS was 47, 84, and 50 months for these groups. Multivariate Cox regression analysis revealed that patients receiving surgery + chemotherapy exhibited a significantly enhanced OS (hazard ratio (HR) = 0.60, 95% confidence interval (CI): 0.38 - 0.94; P = 0.028) compared to those undergoing surgery alone. However, the integration of radiotherapy did not improve OS compared to surgery alone (HR = 0.72, 95% CI: 0.44 - 1.15; P = 0.170).

Conclusion: Adjuvant chemotherapy improved OS compared to surgery alone. However, the addition of radiotherapy did not prolong OS.

接受手术治疗的 T1-2N0M0 期小细胞肺癌患者的治疗模式和生存结果：回顾性队列研究

背景该研究旨在明确接受手术治疗的T1-2N0M0期小细胞肺癌（SCLC）患者的治疗方式和生存结果：方法：调查了2000年至2020年期间来自监测、流行病学和最终结果数据库的小细胞肺癌患者。采用 Kaplan-Meier 生存分析法评估不同治疗策略下的癌症特异性生存（CSS）和总生存（OS）：研究共纳入 190 名患者。治疗方式包括：65 名患者（34.2%）接受了单纯手术治疗，70 名患者（36.8%）接受了手术+化疗，3 名患者（1.6%）接受了手术+放疗，52 名患者（27.4%）接受了手术+化放疗。单纯手术组的中位CSS仍未确定，而手术+化疗组和手术+化放疗组的中位CSS分别为123个月和113个月。这些组别的中位OS分别为47、84和50个月。多变量考克斯回归分析显示，与单独接受手术的患者相比，接受手术+化疗的患者的OS显著提高（危险比（HR）=0.60，95%置信区间（CI）：0.38 - 0.94；P = 0.028）。然而，与单纯手术相比，联合放疗并未改善OS（HR = 0.72，95% CI：0.44 - 1.15；P = 0.170）：结论：与单纯手术相比，辅助化疗可改善患者的生存期。结论：与单纯手术相比，辅助化疗可改善患者的生存期，但增加放疗并不能延长患者的生存期。

期刊介绍： World Journal of Oncology, bimonthly, publishes original contributions describing basic research and clinical investigation of cancer, on the cellular, molecular, prevention, diagnosis, therapy and prognosis aspects. The submissions can be basic research or clinical investigation oriented. This journal welcomes those submissions focused on the clinical trials of new treatment modalities for cancer, and those submissions focused on molecular or cellular research of the oncology pathogenesis. Case reports submitted for consideration of publication should explore either a novel genomic event/description or a new safety signal from an oncolytic agent. The areas of interested manuscripts are these disciplines: tumor immunology and immunotherapy; cancer molecular pharmacology and chemotherapy; drug sensitivity and resistance; cancer epidemiology; clinical trials; cancer pathology; radiobiology and radiation oncology; solid tumor oncology; hematological malignancies; surgical oncology; pediatric oncology; molecular oncology and cancer genes; gene therapy; cancer endocrinology; cancer metastasis; prevention and diagnosis of cancer; other cancer related subjects. The types of manuscripts accepted are original article, review, editorial, short communication, case report, letter to the editor, book review.
