Recurrence patterns and complications in endometrial adenocarcinoma with cervical involvement

Abstract

Cervical involvement in endometrial carcinoma is a diverse entity, and the optimal management of these patients is not well understood. Recurrence patterns and complications in 202 patients with histologically confirmed endometrial carcinoma with cervical involvement were retrospectively studied. The 5-year actuarial survival rate for all patients was 65%. Recurrences were documented in 80 (40%) of the patients, and the overall long-term survival rate in this group was 4%. Patients treated with radical hysterectomy (n = 33) had a 6% isolated pelvic recurrence rate and the lowest serious complication rate among the five treatment groups despite having the highest frequency of risk factors for recurrence among any of the groups studied. Patients treated with extrafascial hysterectomy alone (n = 37) had a 14% pelvic recurrence rate and very few complications. When radiotherapy preceded extrafascial hysterectomy (n = 37), the frequency of pelvic recurrences was 30%, and 19% experienced serious gastrointestinal or genitourinary tract complications. When radiotherapy followed extrafascial hysterectomy (n = 68), the pelvic recurrence rate was 24%, and 13% experienced serious complications. Overall, 24% of patients (49 of 202) had isolated pelvic recurrences, whereas 10% (21 of 202) had isolated distant recurrences and 5% (10 of 202) were simultaneously diagnosed with both pelvic and distant recurrences. This large data base suggests that older conventional forms of therapy, particularly those using preoperative radiotherapy, subject the patient to significant morbidity over a 5- to 10-year period and, in terms of local control, are not necessarily superior to therapeutic modalities using primary surgical evaluation, such as radical hysterectomy. Consideration of primary surgery should be given in the appropriate situation, and radical hysterectomy should be considered when gross cervical involvement is encountered and intraoperative exploration does not show obvious extrauterine disease.
