Long-term results of salvage radiotherapy for the treatment of recurrent cervical carcinoma after prior surgery

AbstarctBackground and purposeTumor recurrence after surgery for cervical carcinoma is associated with high fatality and morbidity, forming a major therapeutic challenge. This paper presents our experience with treatment of this patient group by salvage radiotherapy with curative intent.Materials and methodsThirty-five patients with a pelvic recurrence after hysterectomy received high-dose radiotherapy. A retrospective analysis of long-term outcome and prognostic factors was performed.ResultsAfter a median follow-up period of 12.1 years, actuarial 2-,5- and 10-year overall survival rates were 66%, 43% and 33%; disease-free survival rates were 62%, 45% and 41%, respectively. Pelvic control rates at 2-,5- and 10-years were 77%, 69% and 62%. Unfavorable prognostic factors on univariate analysis for survival were: recurrence extending to the pelvic wall versus central recurrence, early recurrence after surgery, external boost versus brachytherapy boost, low total dose and high age. Only a brachytherapy boost and a long interval between surgery and recurrence were significant on multivariate analysis. Severe complications (⩾grade 3) were seen in 6 patients (17%; actuarial after 5 years, 21%).ConclusionsSalvage radiotherapy for recurrent cervical carcinoma following surgery may result in 40–50% long-term disease-free survival and an acceptable risk of severe treatment complications, even in patient with recurrences extending to the pelvic wall.
