Role of wide/radical hysterectomy and pelvic lymph node dissection in endometrial cancer with cervical involvement.

OBJECTIVE

The goal of this work was to assess retrospectively the role of wide/radical hysterectomy (RH) and pelvic lymph node dissection (LND) in endometrial cancer with cervical involvement. METHODS; From 1984 to 1993, 82 patients with endometrial cancer and cervical involvement were surgically managed at our institution. Of 57 patients with stage II (59%) or III (41%) disease receiving no preoperative therapy, 22 (39%) had simple hysterectomy (SH) and 35 (61%) had RH. Forty-four patients (77%) had pelvic LND, and 38 (67%) had adjuvant radiotherapy (RT). Median follow-up was 70 months.

RESULTS

The 5-year disease-related survival (DRS) and recurrence-free survival (RFS) were 73 and 63%, respectively. Five-year DRS and RFS were 68 and 50%, respectively, in the SH group compared with 76% (P = 0.1) and 71% (P = 0.04) in the RH group. Distant recurrences occurred in 45% of patients with SH and in 23% with RH (P = 0.08). Local recurrence rates did not differ significantly. Considering only stage II tumors, we did not observe any recurrence among patients with negative nodes who had RH, irrespective of the administration of adjuvant RT. By contrast, adjuvant RT improved local control (even if not significantly) in stage II patients who had SH. Five-year DRS of stage III patients was 47%, but it was improved by adjuvant RT in the subgroup of patients who had RH. Independent variables associated with prognosis were stage III disease, deep myometrial invasion, RH, and adjuvant RT.

CONCLUSION

RH and adjuvant RT appear to improve prognosis in endometrial cancer with cervical involvement. In particular, radical surgery alone is therapeutic in stage II patients with negative nodes, irrespective of the administration of RT. By contrast, RT can possibly improve local control in stage II patients who previously had SH. Overall, stage III patients have a poor prognosis that can be improved by a combination of radical surgery and adjuvant RT; however, associated therapy directed to extrapelvic sites is probably needed in patients with extrauterine disease.
