Radioterapia posoperatoria de intensidad volumétrica modulada hipofraccionada con refuerzo simultáneo integrado en sarcomas de partes blandas

Palabras clave: Radioterapia de intensidad modulada, sarcoma, supervivencia, toxicidad

Resumen

Los sarcomas de partes blandas son neoplasias poco frecuentes cuyo tratamiento estándar combina cirugía y radioterapia. Los esquemas convencionales de radioterapia posoperatoria implican tratamientos prolongados, lo que ha motivado la exploración de alternativas hipofraccionadas. El desarrollo de técnicas avanzadas, como la radioterapia de intensidad modulada y la radioterapia volumétrica, junto con el uso de refuerzo simultáneo integrado, permite administrar dosis biológicamente equivalentes en menor tiempo, optimizando la distribución de dosis y reduciendo la irradiación a tejidos sanos. Se presenta una serie retrospectiva de 51 pacientes con sarcoma de partes blandas tratados con radioterapia posoperatoria hipofraccionada en 15 fracciones. Se evaluaron la toxicidad aguda y tardía, y los resultados oncológicos. Los resultados muestran un control local y una supervivencia adecuados, una baja incidencia de toxicidad aguda y una tasa moderada de fibrosis tardía. Estos hallazgos sugieren que el hipofraccionamiento con radioterapia de intensidad modulada/radioterapia volumétrica constituye una alternativa terapéutica viable en contextos seleccionados.
