Abstract
- Aim: This study aims to evaluate the long-term treatment outcome of conventional and hypofractionation radiotherapy in postmastectomy cancer breast patients. Material and Methods: A total of 140 postmastectomy breast cancer patients were included in this retrospective study, who were treated from 2012 to 2014 with chemotherapy and various fractionation radiotherapy schedules. Radiotherapy treatment records for study group-I received radiotherapy 4256 cGy in 16 fractions over 31/2 weeks, group-II patients received 4005 cGy in 15 fractions over 3 weeks, and conventional radiotherapy group-III received 5000 cGy in 25 fractions over 5 weeks. Results: The median follow-up of patients from all groups was 60 months (range 9 to 111 months). There were 39 cases with disease failure, 13 (26%) in group I (42.56 Gy), 16 (40%) in group II (40.05 Gy), and 10 (20%) in group III (50 Gy). There were 4 locoregional recurrences (LRRs), two isolated, and 11 distant failures in group I, 3 LRRs (1 isolated LRR) and 15 distant failures in group II, and only one LRR and 9 distant failures in group III. The disease-free survival (DFS) were 74%, 60%, and 80%, respectively, in groups I, II, and III (P =0.044). Conclusion: The long-term results of this study show that hypofractionation radiotherapy in postmastectomy cases is well tolerated and acute and late side effects are also comparable to conventional fractionation. In our study, locoregional and distant failure seems slightly higher with hypofractionation schedules than in other studies, highlighting the need for more studies with long-term follow-up in postmastectomy patients.
