简要总结
This is a study that will be conducted in rectal cancer patients with distant disease spread to involve peritoneum only. This study will be done for determining the efficacy and safety of intraperitoneal chemotherapy which is delivered directly into the peritoneum i.e the abdominal cavity along with intravenous chemotherapy in rectal cancer patients with peritoneal metastasis.
A total of 92 patients will be enrolled into the study over a period of 3 years. The study will be conducted in 2 phases. The first phase will enroll 10 patients each into the different dosage schedules of intraperitoneal chemotherapy with paclitaxel to find the safe dose of drug to be administered. Then in the next phase total of 72 patients will be evaluated (including 10 patients from the first phase) to look at the efficacy of the intraperitoneal chemotherapy dose that came out to be safe from the first phase of the study.
Patients aged more than 18 years who are diagnosed with confirmed rectal cancer and having evidence of peritoneal disease on staging evaluation will be considered for screening and inclusion into the study. The patients will first undergo a staginglaproscopy procedure to calculate the involvement of peritoneum by cancer by an index called PCI. If the PCI is more than 12 the patients will be screened for eligibility as per the study inclusion and exclusion criteria. After written informed consent the patients will then receive treatment with combined intraperitoneal chemotherapy with a drug called Paclitaxel and intravenous chemotherapy with a regime called FOLFIRI, both given at 2 weekly intervals. The response to treatment will be then assessed by repeat staging laproscopy procedure done at 8 weeks. The response rates, toxicity rates and survival benefits of the treatment will be estimated at the completion of study recruitment.
