About

This is a single-center study design, and 30 patients will be enrolled. Eligible patients will receive docetaxel at different dose levels according to the trial schedule.All the enrolled patients were treated with docetaxel during the first HIPEC treatment and cisplatin during the second HIPEC treatment at 43℃ for 1 hour.The dose of docetaxel for patients in the next group was determined according to the incidence of dose-limiting toxicity (DLT) of the previous docetaxel dose level. Finally, the maximum tolerated dose (MTD) of docetaxel for HIPEC was calculated according to the incidence of dose-limiting toxicity.

Full description

This is a single-center study design, and 30 patients will be enrolled. Eligible patients will receive docetaxel at different dose levels according to the trial schedule. All the enrolled patients were treated with docetaxel during the first HIPEC treatment and cisplatin during the second HIPEC treatment at 43℃ for 1 hour. Four dosages of docetaxel were set up in the study. We decided to take the initial dose of 60mg/m2 and increase the remaining dose gradient by 5 mg/m2. The dosage of cisplatin was 75mg/m2. Time-to-event Bayesian Optimal Interval Design(TITE-BOIN) was used, with 3 patients as an observation group (i.e. a cohort), starting from a dose of 60mg/m2. The dose of docetaxel for patients in the next group was determined according to the incidence of dose-limiting toxicity (DLT) of the previous docetaxel dose level. Finally, the maximum tolerated dose (MTD) of docetaxel for HIPEC was calculated according to the incidence of dose-limiting toxicity.

  2. No history of radiotherapy or chemotherapy in recent 3 weeks.
  3. In addition to HIPEC, docetaxel and cisplatin should be used by other means within 3 weeks after HIPEC treatment.
