ABSTRACT
PURPOSE:
Primary breast sarcomas are heterogeneous tumours derived from non-epithelial mammary gland structures. Although they represent a rare entity, their incidence may increase in the coming years owing to conservative approach considered in the treatment of breast cancer. The aim of this work was to highlight the effect of postoperative irradiation in the treatment of these tumours. MATERIALS ANDMETHODS:
This is a retrospective study conducted at the Mohammed-VI centre for cancer treatment between 2004 and 2011. Survival rates were calculated by the Kaplan-Meier method.RESULTS:
Fifteen cases were collected. The median age was 41.9years. Phyllode sarcoma accounted for 66% of this series. Surgical treatment was performed in 93% of the patients with negative margins in 33.33% of the cases. Neoadjuvant chemotherapy was indicated in 46% of the patients with locally advanced tumours and 66% of the patients received postoperative radiotherapy for positive or close margins. Five years overall survival and relapse free survival was not significantly different with the use of adjuvant radiotherapy.CONCLUSION:
Due to the rarity of this entity and the absence of randomized trials, evidence based management is still lacking. However, a multidisciplinary approach is to be required including surgical excision followed by radiotherapy, depending on the tumour characteristics.Palabras clave
