Clinical trials

In a multicentric randomized controlled trial, we will compare standard surgery (consisting in removal of the primary cancer) followed by 6 months of adjuvant chemotherapy associated with 3 cycles of oxaliplatin-based PIPAC (4-6 weeks apart), to standard surgery followed by 6 months of adjuvant systemic chemotherapy (routine treatment), in patients with colorectal cancer at high risk for metachronous peritoneal carcinomatosis (pT4 pN0-2 cM0 pMMR colorectal cancer of the colon, colorectal junction or high rectum and/or with positive cytology) in terms of 1-year and 3-year peritoneal metastasis-free survival (as measured by imaging and/or surgical exploration), 1-year and 3-year disease-free survival, as well as 1-year and 3-year overall survival. In terms of outcomes measurement, patients in both groups will benefit from diagnostic laparoscopy at 6 months from the index surgery, and standard surveillance consisting in clinical examination, CEA determination and thoraco-abdominal CT at 6, 12, 24, 36, 48 and 60 months after index surgery.

Robotic right hemicolectomy with intra-corporeal anastomosis may have better short-term recovery outcomes and decreased incidence of incisional hernia when compared to the laparoscopic actual standard of care, for similar safety outcomes.
