Background: Colorectal cancer is the second leading cause of cancer-related mortality worldwide. Peritoneal metastases carry the worst prognosis among all sites of colorectal cancer metastases. In recent years, the advent and acceptance of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have greatly improved survival for selected patients with low-volume peritoneal metastases.
Objective: Here, we report the evolution of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases at a statewide tertiary referral center over an 8-year period.
Design: This is a retrospective study from 2009 to 2017.
Setting: The study was conducted at a single center over 8 years.
Patients: Patients with colorectal peritoneal metastases undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were included.
Main Outcomes: Main outcomes included evaluation of grade III/IV morbidity rate, mortality rate, overall and relapse-free survival, and prognostic factors influencing survival on a Cox multivariate analysis model.
Results: One hundred one cytoreductive surgeries were undertaken on 96 patients during this time for colorectal peritoneal metastases. The median patient age was 60 years with 55.2% being female. The median Peritoneal Carcinomatosis Index was 9, with complete cytoreduction achieved in 76 (75.2%) cases. Grade III or IV complications occurred in 26 cases (25.7%) with 2 (2%) perioperative mortalities. Median overall survival for the entire cohort was 32 months, with a 3-year survival of 38%. For patients who achieved a complete cytoreduction, median overall survival was 37 months, with a relapse-free survival of 13 months and a 3-year survival of 54%. Complete cytoreduction and nonmucinous histology were key factors independently associated with improved overall survival.
Limitations: The main limitation this study is its retrospective nature.
Conclusion: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for isolated low-volume colorectal peritoneal metastases is safe and effective, with low morbidity. It offers selected patients a highly favorable overall and relapse-free survival. See Video Abstract at http://links.lww.com/DCR/B2. EVOLUCIÓN DE LA CIRUGÍA CITORREDUCTIVA Y QUIMIOTERAPIA INTRAPERITONEAL HIPERTÉRMICA (HIPEC) PARA METÁSTASIS PERITONEALES COLORRECTALES: EXPERIENCIA INSTITUCIONAL DE 8 AÑOS: El cáncer colorrectal es la segunda causa de mortalidad relacionada con el cáncer en todo el mundo. Las metástasis peritoneales tienen el peor pronóstico entre todos los sitios de metástasis del cáncer colorrectal. En los últimos años, el advenimiento y la aceptación de la cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica ha mejorado enormemente la supervivencia de pacientes seleccionados con metástasis peritoneales de bajo volumen.
Objetivo: Aquí, informamos sobre la evolución de la cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica para las metástasis peritoneales colorrectales en un centro de referencia terciario para todo el estado durante un período de ocho años. DISEÑO:: Estudio retrospectivo del 2009 a 2017. CONFIGURACIÓN:: Centro único a lo largo de ocho años.
Pacientes: Pacientes con metástasis peritoneales colorrectales sometidos a cirugía citorreductiva y quimioterapia intraperitoneal hipertérmica.
Resultados Principales: Los resultados principales incluyeron la evaluación de la tasa de morbilidad de grado III / IV, la tasa de mortalidad, la supervivencia general y libre de recaída y los factores pronósticos que influyen en la supervivencia en el modelo de análisis multivariado Cox.
Resultados: Se realizaron el ciento uno cirugías citorreductivas en noventa y seis pacientes durante este tiempo por metástasis peritoneales colorrectales. La edad media de los pacientes fue de 60 años, con un 55.2% de mujeres. El Índice de Carcinomatosis Peritoneal mediano fue de 9, con una citorreducción completa lograda en 76 (75.2%) casos. Las complicaciones de grado III o IV ocurrieron en 26 casos (25.7%) con dos (2%) de mortalidad perioperatoria. La supervivencia mediana general para toda la cohorte fue de 32 meses, con una supervivencia de 3 años del 38%. Para los pacientes que lograron una citorreducción completa, la supervivencia global media fue de 37 meses, con una supervivencia sin recaída de 13 meses y una supervivencia de 3 años del 54%. La citorreducción completa y la histología no mucinosa fueron factores clave asociados de forma independiente con una mejor supervivencia general.
Limitaciones: La principal limitación es la naturaleza retrospectiva del estudio. CONCLUSIÓN:: La cirugía citorreductiva y la quimioterapia intraperitoneal hipertérmica para las metástasis peritoneales colorrectales aisladas de bajo volumen son seguras y eficaces, con baja morbilidad. Ofrece a los pacientes seleccionados una supervivencia global altamente favorable y libre de recaída. Vea el Resumen del video en http://links.lww.com/DCR/B2.
