Resumen

Objetivo: Describir la experiencia de la RIO en el Hospital Clínica Bíblica, San José, Costa Rica.

Materiales y Métodos: De mayo de 2012 a septiembre de 2014, se ha tratado a 57 pacientes en el Hospital Clínica Bíblica; con haz de electrones con radioterapia intraoperatoria después del tratamiento quirúrgico conservador para el cáncer de mama temprano o avanzado, con refuerzo o como un único tratamiento de radioterapia.

Resultados: La duración promedio de entrega de los tratamientos es de 69,4 segundos (rango: 30s a 128s).

Conclusiones: Un haz de electrones de radioterapia intraoperatoria en el tratamiento conservador del cáncer de mama podría ser considerado una opción adecuada para pacientes de bajo riesgo y algunos pacientes con riesgo intermedio bien seleccionados, o para disminuir el tiempo total del tratamiento en los casos de cáncer de mama tempranos, o como un refuerzo anticipado en estadios avanzados.

Abstract

Objective: Describe the experience of the IOR in the Clinica Biblica Hospital, San Jose, Costa Rica.

Materials and methods: From May 2012 to September 2014 it has treated 57 patients in the Clinica Biblica Hospital with electron beam intraoperative radiotherapy after breast conservative treatment for early or advanced breast cancer, as boost or as a single radiotherapy treatment.

Results: The average duration of delivery of the treatments is 69.4 seconds (rank: 30s to 128s).

Conclusions: The electron beam intraoperative radiotherapy in the conservative treatment of breast cancer could be considered a suitable option for low risk patients and some well-selected intermediate-risk patients, or for decrease the total time of treatment in cases of advanced cancer to use as a boost.
