Resumen

Objetivo: Describir la experiencia de la radioterapia intraoperatoria (RIO) aplicada para cáncer de mama (CM), estadio temprano, en el Hospital Clínica Bíblica.

Materiales y métodos: Se realiza una revisión retrospectiva del registro médico, entre enero de 2014 y diciembre de 2015; 28 pacientes fueron tratadas con cirugía conservadora (CC) y RIO para el CM temprano.

Resultados: No hemos documentada recidiva local, con 28 casos tratados, ni eventos adversos crónicos en piel o pared torácica; 26 de ellas cumplían los criterios según las recomendaciones para irradiación parcial de la mama de la ASTRO y GEC-ESTRO para RIO.

Conclusiones: La RIO con haz de electrones en CC para el CM es una opción adecuada para pacientes de bajo riesgo, con excelente control local sin eventos adversos a piel o pared torácica.

Palabras claves

Cáncer de mama temprano, radioterapia intraoperatoria, radioterapia de haz externo, irradiación de toda la mama, irradiación parcial acelerada de la mama.

Abstract

Objective: Describe the experience of intraoperative radiotherapy (IORT) applied to early stage breast cancer (BC) at Hospital Clínica Bíblica.

Materials and methods: A retrospective review of the medical record was conducted between January 2014 and December 2015; 28 patients were treated with conservative surgery (CS) and IORT for early BC.

Results: We have not documented local recurrence with 28 cases treated, or chronic adverse events in skin or chest wall, 26 of them met the criteria of ASTRO and GEC-ESTRO for IORT.

Conclusions: IORT with electron beam with CS for BC is suitable option for low risk patients, with excellent local control without adverse events to skin or chest wall.

Keywords
