NCT02231086

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Peritoneal Recurrence Free Survival at 18 Months

    Peritoneal recurrence-free survival at 18 months determined by CT and CEA. If CEA was normal and CT did not show any signs of peritoneal metastase at 18 months, a diagnostic laparoscopy was performed in those patients who consented to this intervention. Complete peritoneal staging was performed during laparoscopy, and biopsies were taken from suspicious lesions. If no peritoneal lesions were seen or biopsies were negative, this indicated that the patient was free from peritoneal recurrence.

    18 months

Secondary Outcomes (7)

  • Treatment Related Toxicity of Adjuvant HIPEC

    30 days after adjuvant HIPEC

  • Hospital Stay for Simultaneous and Staged HIPEC, Either Open or Laparoscopic

    10 weeks

  • False-negative Rate of CT-scan for Peritoneal Metastases

    5 years

  • Patterns of Dissemination (Peritoneal Plus or Minus Distant Metastases)

    5 years

  • Disease-free Survival

    5 years

  • +2 more secondary outcomes

Study Arms (2)

Standard adjuvant systemic chemotherapy

ACTIVE COMPARATOR

Standard adjuvant systemic chemotherapy according to the Dutch colon cancer guideline, using a capecitabine and oxaliplatin (CAPOX) or 5-FU and oxaliplatin (FOLFOX) schedule. 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.

Drug: Standard adjuvant systemic chemotherapyProcedure: Diagnostic laparoscopy

Adjuvant HIPEC (open/laparoscopic)

EXPERIMENTAL

Adjuvant HIPEC will be performed simultaneously with primary tumor resection, or as a staged procedure (\<10 days or 5-8 weeks postoperatively). The chemotherapy during oxaliplatin-HIPEC consists of an intravenous phase with leucovorin 20 mg/m2 (maximum 40 mg) and 5-fluorouracil 400 mg/m2 (maximum 800 mg) and an intraperitoneal phase with oxaliplatin 460 mg/m2 (maximal 920 mg). Standard adjuvant systemic chemotherapy according to the national guideline will be given within 3 weeks from HIPEC. 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.

Procedure: Adjuvant HIPEC (open/laparoscopic)Drug: Standard adjuvant systemic chemotherapyProcedure: Diagnostic laparoscopy

Interventions

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.

Also known as: I.V. leucovorin 20 mg/m2 (maximum 40 mg), I.V. 5-fluorouracil 400 mg/m2 (maximum 800 mg), Intraperitoneal oxaliplatin 460 mg/m2 (maximum 920 mg)
Adjuvant HIPEC (open/laparoscopic)

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.

Also known as: adjuvant capecitabine and oxaliplatin (CAPOX), adjuvant 5-FU and oxaliplatin (FOLFOX)
Adjuvant HIPEC (open/laparoscopic)Standard adjuvant systemic chemotherapy

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.

Also known as: Diagnostic laparoscopic surgery
