Prophylactic HIPEC for Colorectal Cancers At High Risk of Developing Peritoneal Metastases

January 30, 2025 updated by: National Cancer Centre, Singapore

Pilot Study: Prophylactic Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for Colorectal Cancers At High Risk of Developing Peritoneal Metastases

The study investigators hypothesize that prophylactic HIPEC is feasible and well tolerated in patients with colorectal cancers with high-risk of developing peritoneal recurrence.

The aim of the pilot study is to test the feasibility of performing prophylactic HIPEC for colorectal cancer patients at high-risk of developing peritoneal recurrence in our institution, and determine the morbidity associated with such a procedure.

Patients with high-risk of developing peritoneal recurrence are defined as patients with

  1. tumours involving the serosa and adjacent viscera (i.e. T4 cancers)
  2. krukenburg tumours (i.e. ovarian metastases)
  3. perforated tumours
  4. positive peritoneal fluid cytology
  5. minimal synchronous PC (nodules <1cm in the omentum and/or close to the primary tumour).

The study investigators plan to assess feasibility according to

  1. The number of patients completing the treatment
  2. Time to adjuvant systemic chemotherapy, to evaluate if there is delay to adjuvant treatment

Morbidity will be measured according to the Clavien-Dindo Classification, and graded according to low versus high grade morbidity.

If prophylactic HIPEC is shown to be feasible, with acceptable morbidity, the investigators aim to carry out a randomized controlled trial to determine the effectiveness of prophylactic HIPEC in preventing the development of peritoneal metastases in patients with colorectal cancer at high risk of peritoneal recurrence.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

Two groups of patients may be enrolled:

Group 1 patients are identified pre-operatively on radiological imaging, while Group 2 patients are identified post-operative based on histological findings.

All patients diagnosed with adenocarcinoma of the colon and rectum, and either one of the five following risk factors for peritoneal metastases will be considered for inclusion:

  1. T4 tumours - in Group 1, this would consist of obvious clinical T4 stage based on preoperative imaging, and in Group 2, this would be on pathological confirmation of a T4 tumour.
  2. Krukenburg tumours - Unilateral or bilateral ovarian masses seen on preoperative imaging
  3. Perforated tumours - in Group 1, this would consist of patients presenting with perforation on preoperative imaging, and undergoing curative resection, and in Group 2, this would be on pathological or intra-operative confirmation of a perforated tumour.
  4. Limited synchronous peritoneal metastases (peritoneal nodules <1cm in the omentum and/or close to the tumour). Patients with limited peritoneal disease in close proximity to the primary tumour, that may be removed enbloc with the primary resection can be included, but patients with more extensive peritoneal disease and those with extra-peritoneal metastases i.e. liver and/or lung metastases will be excluded from the study.
  5. Positive cytology in Group 2 patients

Other inclusion criteria:

  1. Patients must be between the ages of 21 and 75 years
  2. Patients must be in a stable clinical condition to undergo simultaneous HIPEC after the primary curative colorectal resection
  3. Patients must have an ECOG performance status 0 or 1
  4. Patients must have normal organ and marrow function as defined below:

i. Absolute neutrophil count > 1.5 x 109/L ii. Platelets > 100 x 109/L iii. Haemoglobin > 9.0g/dl iv. Total bilirubin ≤1.5 x ULN v. AST(SGOT)/ALT(SGPT) < 3 X institutional ULN vi. Creatinine ≤1.5 x upper limit of normal (ULN) OR vii. Creatinine clearance ≥60 mL/min for patients with creatinine levels >1.5 x institutional UL e. Patients must have a normal coagulation profile f. Patients must give written informed consent

Exclusion Criteria:

  1. Patients who are not fit to give consent for the procedure
  2. Patients who are not fit to undergo surgery
  3. Patients who are pregnant
  4. Patients who have extensive synchronous peritoneal disease
  5. Patients with extra-peritoneal metastases i.e. liver and/or lung metastases

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group 1
Patients are identified pre-operatively on radiological imaging. Prophylactic HIPEC will be delivered intra-operatively, immediately after the resection of the primary tumour, and only if the patient is deemed well enough to receive the HIPEC.
Procedure: HIPEC
All HIPEC will be with Mitomycin C and given at a dose of 10mg/body surface area.
Experimental: Group 2
Patients are identified post-operative based on histological findings. They will be counselled to receive prophylactic HIPEC only. If peritoneal nodules are found during surgery, these patients will be excluded from the study.
Procedure: HIPEC
All HIPEC will be with Mitomycin C and given at a dose of 10mg/body surface area.
