    Abstract:
    OBJECTIVE: We aimed to identify prognostic factors of early-stage cervical adenocarcinoma (AC) and adenosquamous carcinoma (ASC) treated with primary radical surgery, and to evaluate the impact of postoperative adjuvant therapy on outcome. METHODS: The clinical-pathological data of all patients (n = 1132) with stages I-II cervical AC/ASC treated with primary radical surgery at the member hospitals of the Taiwanese Gynecologic Oncology Group were retrospectively reviewed. RESULTS: In multivariate analysis, stage II, deep stromal invasion (DSI), lymphovascular space invasion (LVSI), positive pelvic lymph node (PLN), and parametrial involvement (PI) were significant factors for recurrence-free survival (RFS), while only DSI, PI, and positive PLN were independent factors for cancer-specific survival (CSS). Low- and high-risk groups were defined by prognostic scores derived from the four factors (DSI, LVSI, positive PLN, PI) selected by internal validation. Postoperative adjuvant therapy significantly improved outcome for PLN-positive patients (RFS, p = 0.014; CSS, p = 0.016), but not for PLN-negative high-risk group because of higher mean prognostic score (p = 0.028) of adjuvant+ than adjuvant- patients. CONCLUSIONS: PLN metastasis, PI, DSI, and LVSI were independent prognostic factors. Prospective studies of postoperative adjuvant therapy with prognostic score and nodal status stratification for cervical AC/ASC are necessary.
