Retrospective analysis of surgery for cervical stump carcinoma at early stage

Subtotal hysterectomy reviewed: a stable or aperture for stump cervical malignancy. A referral hospital experience

Introduction

To review the malignant potential of the stump after subtotal abdominal hysterectomy. Material and methods: Thirty-three patients with stump malignancy were diagnosed and treated between January 2018 and January 2022. All patients primarily underwent subtotal hysterectomy (STH) outside our hospital due to different indications, most of which seemed non-convincing. Upon presentation, they were evaluated properly and offered the best management plan.

Results

The presenting symptoms were abnormal histopathology report in 8 patients (24.24%), abnormal bleeding in 7 patients (21.21%), and postcoital bleeding and abnormal Pap smear in 6 patients (18.18%). The primary site of malignancy was endometrial in 17 patients (51.51%), on top of fibroid in 6 patients (18.18%), and cervical in 5 patients (15.15%). Eighteen patients (54.54%) underwent proper surgery, 9 patients (27.277%) were referred for chemoradiation, and 6 patients (18.18%) were candidates for palliative therapy.

Conclusions

Stump cancer cases show a worse stage silhouette compared with cancer cases in intact uteruses. The high prevalence of cervical stump problems should be taken into account before a change in surgical approach from total to STH is deemed possible. Further prospective studies with prolonged follow-up periods are needed to evaluate the risks and benefits of retaining the cervix at hysterectomy. Subtotal hysterectomy is easier, does not require distinct skills that lead to experience and follow-up, and must be limited to the narrowest limits of practice, provided that the woman knows that there are no health benefits to keeping the cervix in place.

Characteristics, complications, and outcomes of early-stage cervical stump carcinoma: laparoscopy versus laparotomy

Objective

To compare the characteristics, surgical complications, and overall survival between patients undergoing laparoscopy versus laparotomy for treatment of early-stage cervical stump carcinoma.

Methods

Patients with International Federation of Gynecology and Obstetrics (FIGO, 2009) stage IA2 to IIA2 cervical stump carcinoma who underwent laparoscopy or laparotomy in the Obstetrics and Gynecology Hospital of Fudan University from January 2000 to June 2018 were retrospectively reviewed. All patients’ clinical characteristics, pathological features, complications, and follow-up data were retrieved.

Results

Seventy-two patients were included in the analysis; 58 underwent laparoscopy and 14 underwent laparotomy. With respect to surgical complications, laparoscopy was associated with a significantly lower complication rate, less blood loss, a shorter operative time, and a higher hospitalization fee than laparotomy. Survival was not significantly different between the laparoscopy and laparotomy groups.

Conclusions

Although survival was not significantly different between the two surgical approaches, the rate of surgical complications was much lower in the laparoscopy than laparotomy group.

Cervical Stump Cancer Treated With Radiotherapy Using Computed Tomography-Guided Brachytherapy

Cervical stump cancer, which arises in the remaining uterine cervix of a woman with a history of supravaginal hysterectomy, accounts for 1.6-4.4% of all cervical cancers. The close proximity of the rectosigmoid colon to the primary tumor, which is due to the absence of the uterine corpus, should be considered carefully in the treatment planning of brachytherapy. Although three-dimensional image-guided brachytherapy (3D-IGBT) is used widely to treat cervical cancer in those with an intact uterine corpus, the safety and efficacy of 3D-IGBT for cervical stump cancer remains unclear. Here, we report a case of cervical stump cancer (T3bN1M0) treated successfully with definitive radiotherapy, which combined external beam radiotherapy and computed tomography (CT)-based IGBT. By applying the dose prescription concept used for definitive brachytherapy of cervical cancer with an intact uterine corpus, IGBT achieved satisfactory dose conformity to the tumor while sparing the adjacent rectosigmoid colon. This led to local tumor control for three years and eight months, with no late adverse effects. This case suggests that radiotherapy using CT-based IGBT is a safe and effective treatment for cervical stump cancer.
