A phase I dose-finding trial of hyperthermic intraperitoneal docetaxel combined with cisplatin in patients with advanced-stage ovarian cancer

To identify the maximum tolerated dose (MTD) of docetaxel combined with a fixed dose of cisplatin (75 mg/m²) delivered as hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with ovarian cancer. In this phase I trial, a time-to-event Bayesian optimal interval design was used. Docetaxel was given at a starting dose of 60 mg/m² and was increased in 5 mg/m² increments until the MTD was determined or the maximum dose level of 75 mg/m² was reached. The dose-limiting toxicity (DLT) rate was set at 25%, with a total sample size of 30 patients. HIPEC was delivered immediately following debulking surgery at a target temperature of 43°C for 90 minutes. From August 2022 to November 2022, 30 patients were enrolled. Among the patients who received a dose of docetaxel ≤65 mg/m², no DLT was reported. DLTs were observed in one patient who received 70 mg/m² docetaxel (grade 3 anaemia) and in three patients who received 75 mg/m² docetaxel (one case of grade 3 anaemia, one case of grade 3 hepatic impairment and one case of grade 4 thrombocytopenia). Patients treated with docetaxel 75 mg/m² in combination with cisplatin 75 mg/m² had an estimated DLT rate of 25%, which was the closest to the target DLT rate and was therefore chosen as the MTD. Docetaxel, in combination with a fixed dose of cisplatin (75 mg/m²), can be used safely at intraperitoneal doses of 75 mg/m² in ovarian cancer patients who received HIPEC (43°C, 90 minutes) following debulking surgery.

Administration of Hyperthermic Intraperitoneal Chemotherapy in the General Ward

Ovarian cancer is the most lethal gynecologic malignancy. The majority of patients get diagnosed with advanced disease with peritoneal dissemination.It has been demonstrated that the addition of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) to interval debulking surgery can improve the prognosis. The National Comprehensive Cancer Network (NCCN) treatment guideline has recommended HIPEC as a first-line treatment for patients with advanced ovarian cancer. However, the guideline recommended the "Dutch model" of HIPEC, which is limited for routinely being performed in China. So we propose a HIPEC treatment modality, the bedside closed HIPEC in the general ward (C-HIPEC), which is suitable for the clinical characteristics of China. The aim of this study was to evaluate the safety of this model as a way to lay the foundation for subsequent efficacy evaluation and clinical promotion.
