title: [Usefulness of adjuvant chemotherapy with antimetabolites for cervical invasive cancer].
abstract: A series of 584 patients with cervical invasive cancer were included in the retrospective study on the efficacy of long-term oral maintenance chemotherapy with antimetabolites (Fluorouracil or Tegaful). The patients were histologically classified into the squamous cell carcinoma (SCC) group and the adenocarcinoma (AD) group. In the SCC group (n = 518), 163 patients were given more than 300 mg/day of antimetabolite tablets for one year or more after the main therapy (hysterectomy or pelvic irradiation). In the AD group (n = 66), 36 patients were treated with the same dose of antimetabolites. The Kaplan-Meier overall and cancer specific survival analysis estimates that the chronic administration of antimetabolites did not improve the cumulative 5-year survival in the SCC group. In contrast, the cumulative 5-year survival rate in the AD group treated with antimetabolites (88%) was significantly higher than that without chemotherapy (64%) by Kaplan-Meier analysis. This significant improvement in the survival rate in the AD group due to antimetabolites was notable in patients in FIGO stage I or II treated with radical or semiradical hysterectomy, these results indicate that oral adjuvant chemotherapy with antimetabolites is useful for cervical adenocarcinoma, but not for squamous cell carcinoma.
