The study is to evaluate the difference between outcomes of two high-dose-rate fractionation schedules in the treatment of intracavitary brachytherapy (ICBT) of cervical cancer.

Material and methods
A retrospective analysis of 163 cervical cancer patients was completed. All patients received external beam radiotherapy (EBRT) to whole pelvis with concurrent weekly chemotherapy, followed by ICBT with either 7 Gy per fraction in three fractions (arm A) or 9 Gy per fraction in two fractions (arm B). Median follow-up was 19 months. The outcomes were compared in terms of 2-year actuarial local control, disease-free survival, overall survival, and late toxicity in the two treatment arms.

The 2-year actuarial local control rates in arm A and arm B were 88.5% and 91.5%, respectively. The actuarial 2-year disease-free survival rates in arm A and arm B were 85.9% and 82.6%, respectively. The actuarial 2-year overall survival in arm A and arm B were 95.7% and 100%, respectively (p = 0.06). There were 12.7% and 15.2% local failures in arm A and arm B, respectively. Distant metastases were seen in 8.5% and 7.6% in arm A and arm B, respectively. The 2-year actuarial risk of developing late rectal toxicity in arm A and arm B were 5.6% and 5.4%, respectively. The 2-year actuarial risk of developing late bladder toxicity in arm A and arm B were 2.8% and 2.2%, respectively.

ICBT treatment with 9 Gy in two fractions offers equivocal local control rates and survival rates in cancer cervix cases with many advantages of short overall treatment time, improved patient compliance, cost effectiveness, and reduced exposure to aesthetic agents. The toxicities observed were few, low grade, and easily manageable.
