Résumé : Histologic growth patterns (HGPs) of both peritoneal metastasis (PM) and liver metastasis (LM) have emerged as prognostic factors for patients undergoing curative surgery for metastatic colorectal cancer (CRC). The main objectives of the study were, first, to evaluate the correlation between PMHGP and LMHGP of CRC patients who underwent curative-intent cytoreductive surgery (CRS) and LM resection and, second, to assess the prognostic impact of HGP type.
