High-dose tamoxifen plus ifosfamide and anthracycline in a patient with angiosarcoma of the breast / Tamoxifen en dosis alta con ifosfamida y antraciclina en un paciente con angiosarcoma de mama

Although breast cancer is, unfortunately, not uncommon in women, a mere 0.04% of malignant breast tumours are primary angiosarcomas. Chemotherapy is advocated for treatment of breast angiosarcomas; however, no guidelines exist regarding optimal chemotherapeutics or protocols. Presently, the prognosis for breast angiosarcomas is poor. This case report describes a 24-year old woman diagnosed with primary breast angiosarcoma. She initially refused to receive treatment, but later returned to the hospital four years later with a haemopneumothorax. She was treated with rescue chemotherapy using a combination of high-dose tamoxifen plus ifosfamide and epirubicin (an anthracycline). She achieved a partial response, but died 16 months after therapy was initiated. More research is needed to devise novel chemotherapeutics and protocols to improve outcomes in women diagnosed with primary angiosarcomas ofthe breast.

Aunque el cáncer de mama, desafortunadamente, no es poco común en las mujeres, apenas 0.04% de los tumores malignos de mama son angiosarcomas primarios. La quimioterapia es el tratamiento de preferencia en los casos de angiosarcomas de mama. Sin embargo, no existen guías en relación con los protocolos o la quimioterapia óptima. En la actualidad, el pronóstico para los angiosarcomas de mama es pobre. Este informe del caso describe a una mujer de 24 años diagnosticada con angiosarcoma primario de mama. Inicialmente la paciente se negó a recibir tratamiento, pero volvió al hospital cuatro años más tarde con un hemoneumotórax. Fue tratada entonces con quimioterapia de rescate usando una combinación de alta dosis de tamoxifen con ifosfamida y epirrubicina (antraciclina). Llegó a responder parcialmente al tratamiento, pero falleció 16 meses después del inicio de la terapia. Se necesitan más investigaciones para elaborar nuevos quimioterápeuticos y protocolos que mejoren los resultados en los casos de mujeres diagnosticadas con angiosarcomas primarios de mama.
