PURPOSE: To evaluate the long-term results of salvage radiotherapy for patients of invasive cervical cancer after inadequate surgery.
METHODS AND MATERIALS: Between October 1975 and January 1994, 90 patients were treated with radiotherapy for invasive cervical carcinoma after simple hysterectomy. The inadequate surgery was performed for a variety of reasons. All patients had postoperative external beam irradiation or intravaginal brachytherapy, or both. The end points of this study were local control, survival, and treatment-related toxicity.
RESULTS: The patients' age varied between 33 and 76 with a median of 53 years. The most common histopathology was squamous cell carcinoma, which accounted for 91% of the patients. The most frequent reason for inadvertent hysterectomy was understaged disease with preoperative diagnosis as carcinoma in situ for 51 patients (57%). Malignancy was not suspected before surgery in 28 patients (31%). After surgery, 72 patients (80%) were restaged as Ib, 12 patients (13.3%) as IIa, and 6 patients (6.7%) as IIb. Median follow-up time was 83 months. Seventy-three patients had follow-up times of 5 years or more. The overall 5-year and 10-year survival rates of 90 patients were 85.5% and 74.1%, respectively. Disease-specific 5-year and 10-year survival rates were 85.5% and 80.5%, respectively. All 16 patients with either locoregional or distant failure eventually died of disease. Fourteen patients (15.5%) had late morbidities. Radiation proctitis developed in 6 patients, intestinal obstruction in 4 patients, and hemorrhagic cystitis in 3. There was only 1 patient (1%) with terminal ileum stenosis and severe intestinal obstruction requiring surgical intervention.
CONCLUSIONS: Most cases of inadequately treated invasive cervical cancer were the result of suboptimal preoperative workups. Patients who had early tumors and no gross residual tumor after inadequate hysterectomy can have excellent prognoses when given postoperative radiotherapy. The severe long-term complication related to salvage radiotherapy is rare.
