概要	OBJECTIVE:The study compared the treatment outcomes of surgery versus radiotherapy, including concurrent chemoradiotherapy, in stage Ib2-IIb cervical adenocarcinoma patients in Japan.METHODS:Of 57,470 patients diagnosed with stage I-IV cervical cancer from January 2001-December 2011, 1,932 patients with stage Ib2-IIb cervical adenocarcinoma were initially treated by surgery or radiotherapy. The primary endpoint was 5-year overall survival (OS) in all and 614 propensity score-matched (PSM) patients (307 per group). We compared OS and prognosis factors based on age, primary stage, and treatment arm.RESULTS:In Japan, >80% (n=1,573) of stage Ib2-IIb cervical adenocarcinoma patients underwent surgery. The 5-year OS of surgery vs. radiotherapy groups were 82.1% (n=704) vs. 79.7% (n=59) (hazard ratio [HR]=1.494; 95% confidence interval [CI]=0.826-2.702; p=0.181) for stage Ib2, 76.6% (n=239) vs. 66.7% (n=54) (HR=1.679; 95% CI=0.986-2.858; p=0.053) for stage IIa, and 71.1% (n=630) vs. 58.9% (n=246) (HR=1.711; 95% CI=1.341-2.184; p<0.001) for stage IIb. In 614 PSM patients balanced for age and carcinoma stage Ib2-IIb, the 5-year OS of surgery vs. radiation groups was 73.0% (n=307) vs. 65.5% (n=307) (HR=1.394; 95% CI=1.044-1.860; p=0.023). In multivariable analysis, age (HR=1.293; 95% CI=1.045-1.601; p=0.018), treatment arm, radiotherapy (HR=1.556; 95% CI=1.253-1.933; p<0.001), and stage IIb (HR=1.783; 95% CI=1.443-2.203; p=0.018) were independent prognosis factors for 5-year OS in stage Ib2-IIb adenocarcinoma patients.CONCLUSION:Age (>65 years), treatment arm (radiotherapy), and stage IIb significantly affect OS in cervical adenocarcinoma patients. Surgery may be considered for <65-year-old patients with stage IIb adenocarcinoma.
