Although supracervical hysterectomy is becoming a vanishingly rare procedure, there are still many women with a retained cervical stump. We have reviewed 70 patients treated at the Radiation Oncology Center, Mallinckrodt Institute of Radiology for carcinoma of the cervical stump. The average time between the hysterectomy and the diagnosis of cancer in the stump was 26.6 years. The median age at diagnosis of 63.5 years is 8.5 years older than the median age at diagnosis of patients with cancer of the cervix with an intact uterus. Patients were treated with external beam radiation and/or intracavitary implants. Sixteen patients underwent surgery as well. The 5- and 10-year overall actuarial survival for all patients was 60% and 40%, respectively. The 5- and 10-year progression-free survival for all patients was 77% and 70%, respectively. Ten-year progression-free survival by stage was: 0--100%, 1A--100%, 1B--79%, 2A--100%, 2B--66%, and 3B--39%. Poor histologic differentiation correlated with a decreased long-term progression-free survival. Black patients, and those receiving prolonged courses of external beam irradiation, had a trend toward a worse prognosis. Neither non-squamous histology nor gross appearance affected outcome. With a median follow-up time of 12.9 years, there were only three isolated local failures and four combined with distant metastases. Complications were few, with twice as many occurring in the gastrointestinal system as in the genitourinary tract. We conclude that carcinoma of the cervical stump effectively treated by radiation therapy yields results equivalent to those seen in patients with an intact uterus.
