Primitive sarcomas of the breast
Sarcomas primitivos de mama
Resumen:
Primitive sarcomas of the breast are a very heterogeneous group of tumors, only related to one another by their mesenchymal origin. Clinically, they are undistinguishable from other breast tumors, and in particular, from carcinomas. Definitive diagnosis can only be based on a complete histopathologic study. Simple breast roentgenology, cytologic punction and even partbiopsy may lead to errors. Each histopathologic type has a particular bio-pathology, which requires its own clinical and therapeutic approach. The surgical procedure then depends on the degree of extension and the type of tumor. Radical mastectomy is indicated in rhabdomyosarcoma, in undifferentiated liposarcoma and in hemagiosarcoma; in the rest, a simple mastectomy, or mastectomy associated with pectoral resection and/or axillary dissection is enough.The authors carry out a retrospective clinical and pathological analysis on 16 cases: 10 fibrosarcomas, 3 rhabdomyosarcomas, 2 hemangiosarcomas and 1 malignant mesenchymoma. The treatments applied were varied, in general choosing non-radical procedures. In 8 cases local recurrences occurred. Out of the 10 cases in which a long follow-up could be done, 8 have survivedwithout signs of disease, from 2 to 16 years after surgery.
Los sarcomas primitivos de mama constituyen un grupo de tumores muy heterogéneo, cuyo único nexo de unión es su origen mesenquimal. Clínicamente son indiferenciables de otros tumores mamarios y en particu1ar del carcinoma. El diagnóstico definitivo sólo puede estar basado en un estudio histopatológico completo. La radiología simple de mama, la punción citológica y aun la biopsia-parte, pueden ser engañosas. Cada tipohistopatológico tiene una biopatología particular, que demanda un encare clínico-terapéutico propio. La táctica quirúrgica depende, pues, del grado de extensión y del tipo del tumor. La mastectomía radical está indicada en los rabdomiosarcomas, en el liposarcoma indiferenciado y en el hemangiosarcoma; en los demás, es suficiente la mastectomía simple o asociad.a a resección del pectoral y/o vaciamiento axilar. Los autores realizan un análisis clínico-patológico retrospectivo sobre 16 casos: 10 fibrosarcomas, 3 rabdomiosarcomas, 2 hemangiosaroomas y un mesenquimoma maligno. Los tratamientos aplicados fueron variados obtándose en general por procedimientos no radicales. En 8 casos se produjeron recidivas locales. De los 10 casos en 1os que se pudo hacer un seguimiento prolongado, 8 sobreviven sin signos de enfermeda: de entre 2 y 16 años luego de tratados.
