Histological Growth Pattern Predicts Survival in Peritoneal Metastases

Patients with colorectal peritoneal metastases who underwent cytoreductive surgery had better disease-free and overall survival if they had a dominant pushing histological growth pattern compared to infiltrating pattern. The study confirmed the prognostic value of these patterns regardless of neoadjuvant chemotherapy or extent of peritoneal disease burden. No significant associations were found between neoadjuvant chemotherapy and the type of histological growth pattern.
