Long-term side effects and cosmetic outcome in a pool of breast cancer patients treated with intraoperative radiotherapy with electrons as sole treatment

Tumori. May-Jun 2012;98(3):324-30. doi: 10.1700/1125.12400.

Abstract

Aims: To evaluate late toxicity and cosmetic outcome after intraoperative radiotherapy using electrons (ELIOT) as sole treatment modality in early breast cancer patients.

Methods: A total of 119 patients selected randomly among 1200 cases was analyzed. Late toxicities were documented using the LENT-SOMA scoring system, cosmesis was evaluated with the Harvard scale, and a numeric rating scale was used to assess symptoms.

Results: After a median follow-up of 71 months, grade II fibrosis was observed in 38 patients (31.9%) and grade III fibrosis in 7 patients (5.9%). Postoperative complications (12.6%) did not correlate with late toxicity. Physicians and patients scored cosmesis as excellent or good in 84% and 77.3% of the cases, respectively. Patient satisfaction was higher than 90%.

Conclusions: In the study, ELIOT gives low and acceptable long-term toxicity. A longer follow-up and a larger number of patients are needed to confirm these promising results.
