Adjuvant HIPEC in High Risk Colon Cancer
Condition: Colorectal Neoplasms; Peritoneal Neoplasms
MeSH terms: Neoplasms; Colorectal Neoplasms; Peritoneal Neoplasms
Intervention: Adjuvant HIPEC (open/laparoscopic); Standard adjuvant systemic chemotherapy; Diagnostic laparoscopy
Intervention description: Adjuvant HIPEC procedure: access to the abdominal cavity by laparoscopy or laparotomy under general anaesthesia, adhesiolysis if necessary, complete staging of the intra-abdominal cavity, positioning of in- and outflow catheters, perfusion with a minimum of 2l isotonic dialysis fluid at a flow rate of 1-2l/min and an inflow temperature of 42-43˚C. Before the beginning of HIPEC, 5-fluorouracil 400 mg/m2 and leucovorin 20 mg/m2 will be administered intravenously to potentiate oxaliplatin activity. Oxaliplatin (460 mg/m2) is added to the perfusate after attaining at least 42 degrees inflow temperature with a total of 30 minutes perfusion time.; Colon cancer patients with a high risk of developing PC, but do not have (yet) proven macroscopic peritoneal metastasis, are standardly treated with adjuvant systemic chemotherapy. Standard adjuvant systemic chemotherapy consists in the Netherlands of a capecitabine and oxaliplatin (CAPOX) or 5-FU and oxaliplatin (FOLFOX) for a total of 6 months.; Presence or absence of peritoneal recurrence will be evaluated by laparoscopy in case of negative routine examination (CEA and CT thorax/abdomen) at 18 months postoperatively in both study arms.

Summary:

      This study aims to determine the oncological effectiveness of adjuvant HIPEC, using
      intraperitoneal oxaliplatin with concomitant i.v. 5-FU/LV, following a curative resection of
      a T4 or intra-abdominally perforated Colon cancer in preventing the development of peritoneal
      carcinomatosis in addition to the standard adjuvant systemic treatment.

      Hypothesis:

      The hypothesis is that adjuvant HIPEC preceding routine adjuvant systemic therapy using i.p.
      oxaliplatin with concomitant i.v. 5-FU/LV following a curative resection of a T4 or
      intra-abdominally perforated colon cancer reduces the development of peritoneal
      carcinomatosis in comparison to standard adjuvant systemic treatment alone.
