Résumé
Mastectomy is the standard treatment of in-breast-recurrence of breast cancer after breast conserving surgery (BCS) and external beam radiation therapy (EBRT). In selected cases, it is possible to preserve the breast if targeted intraoperative radiotherapy (TARGIT-IORT) can be given during the second lumpectomy. This is a comparative analysis of overall survival and quality of life (QoL). Patients in our database with in-breast-recurrence and either mastectomy or BCS and TARGIT-IORT were included. Identified patients were offered participation in a prospective QoL-analysis using the BREAST-Q questionnaire. The cohorts were compared for confounding parameters, overall survival, and QoL. Thirty-six patients treated for in-breast-recurrence were included, 21 had received a mastectomy and 16 patients had received BCS with TARGIT-IORT. Mean follow-up was 12.8 years since primary diagnosis and 4.2 years since recurrence. Both groups were balanced regarding prognostic parameters. Overall survival was numerically longer for BCS and TARGIT-IORT, but the numbers were too small for formal statistical analysis. No patient had further in-breast-recurrence. Psychosocial and sexual wellbeing did not differ between both groups. Physical wellbeing was significantly superior for those whose breast could be preserved (p-value=0.021). Patient-reported incidence and severity of lymphedema of the arm was significantly worse in the mastectomy group (p=0.007). Preserving the breast by use of TARGIT-IORT was safe with no re-recurrence and no detriment to overall survival in our analysis and led to a statistically significant improvement in physical wellbeing and incidence of lymphedema. These data should increase the confidence in offering breast preservation after in-breast-recurrence of breast cancer.

BACKGROUND/AIM
OBJECTIVE
Mastectomy is the standard treatment of in-breast-recurrence of breast cancer after breast conserving surgery (BCS) and external beam radiation therapy (EBRT). In selected cases, it is possible to preserve the breast if targeted intraoperative radiotherapy (TARGIT-IORT) can be given during the second lumpectomy. This is a comparative analysis of overall survival and quality of life (QoL).
PATIENTS AND METHODS
METHODS
Patients in our database with in-breast-recurrence and either mastectomy or BCS and TARGIT-IORT were included. Identified patients were offered participation in a prospective QoL-analysis using the BREAST-Q questionnaire. The cohorts were compared for confounding parameters, overall survival, and QoL.
RESULTS
RESULTS
Thirty-six patients treated for in-breast-recurrence were included, 21 had received a mastectomy and 16 patients had received BCS with TARGIT-IORT. Mean follow-up was 12.8 years since primary diagnosis and 4.2 years since recurrence. Both groups were balanced regarding prognostic parameters. Overall survival was numerically longer for BCS and TARGIT-IORT, but the numbers were too small for formal statistical analysis. No patient had further in-breast-recurrence. Psychosocial and sexual wellbeing did not differ between both groups. Physical wellbeing was significantly superior for those whose breast could be preserved (p-value=0.021). Patient-reported incidence and severity of lymphedema of the arm was significantly worse in the mastectomy group (p=0.007).
CONCLUSION
CONCLUSIONS
Preserving the breast by use of TARGIT-IORT was safe with no re-recurrence and no detriment to overall survival in our analysis and led to a statistically significant improvement in physical wellbeing and incidence of lymphedema. These data should increase the confidence in offering breast preservation after in-breast-recurrence of breast cancer.
