El cáncer de origen colorrectal es el tumor digestivo más frecuente. La alta incidencia de su diseminación abdominal, el mal pronóstico de estos pacientes, con una media de supervivencia de 5-9 meses demostrada en todos los estudios sobre la historia natural de la carcinomatosis colorrectal, y el fracaso del tratamiento adyuvante sistémico, con supervivencias máximas de 18 meses, han obligado al estudio y desarrollo de otras estrategias de tratamiento. Se presenta una revisión de los principios que fundamentan el Protocolo de Tratamiento de Sugarbaker, que comprende la máxima cirugía (..) (AU)

Colorectal cancer is the most frequent digestive tumor. The incidence of abdominal dissemination is high and all studies of the natural history of colorectal carcinomatosis demonstrate that prognosis in these patients is poor, with a mean survival of between 5 and 9 months. Furthermore, the results of systemic adjuvant treatment are disappointing, with a maximum survival of 18 months. Consequently, other treatment strategies need to be studied and developed. We present a review of the principles that underlie Sugarbakers treatment protocol, which includes maximal cytoreductive surgery for the treatment of macroscopic disease through peritonectomy together with perioperative intraperitoneal intensification chemotherapy for residual microscopic disease. We present all the phase II studies with more than 10 treated patients published in the medical literature by the main groups working in this line of treatment, together with the only phase III study published to date. With this new therapeutic alternative, the mean overall survival at 2 and 5 years is 40% and 20% respectively. Based on these results, this new therapeutic approach is recommended as the treatment of choice in these unfortunate patients. The limits of the treatment of advanced colorectal cancer are also discussed.
