Management of endometrial adenocarcinoma with cervical involvement

Seventy-seven patients with endometrial cancer with cervical involvement were treated at Memorial Sloan-Kettering Cancer Center from 1968 to 1982. Fractional curettage specimens showed that 25 patients (32%) had involvement of cervical stroma and 52 (68%) had only detached fragments of carcinoma present in endocervical curettings. Six patients treated for palliation only are excluded from analysis of treatment and survival. Our preferred treatment during the time interval studied consisted of preoperative whole pelvic radiotherapy followed by modified radical hysterectomy and bilateral salpingo-oophorectomy with post-operative intravaginal brachytherapy. This regimen was well tolerated by the 37 patients so treated. The remaining patients were treated with a variety of regimens, most commonly radiotherapy and simple hysterectomy (25 patients). With a mean follow-up among survivors of 97 months, disease-free survival is 72%. Mean time to relapse was 19 months, with 90% of relapses occurring within 40 months. Initial sites of relapse included abdomen, 9 (12.6%); lungs, 8 (11.3%); brain, 2 (2.8%); lateral pelvis, 2 (2.8%); and bone, 1 (1.4%). Clinicopathologic variables significantly related to risk of relapse included presence of extrauterine disease at surgery (P = 0.0001), extent of cervical involvement as determined prior to hysterectomy (P = 0.001), depth of myometrial invasion (P = 0.005), and papillary serous histology (P = 0.0002). Treatment of endometrial cancer with cervical involvement with combinations of radiotherapy and surgery is well tolerated and results in an excellent long-term disease-free survival and a low rate of pelvic relapse.
