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.

Round ligament suspension and vaginal purse‐string suture: Newly optimized techniques to prevent tumor spillage in laparoscopic radical trachelectomy for cervical cancer

AbstractAimThe purpose of this study was to investigate the surgical techniques and clinical feasibility of nonuterine manipulator and enclosed colpotomy to avoid cancer cell spillages in laparoscopic radical trachelectomy (LRT) for patients with early‐stage cervical cancer.MethodsWe performed the newly optimized surgical techniques of round ligament suspension and vaginal purse‐string suture in LRT in 12 patients with early‐stage cervical cancer from May 2019 to October 2020. Surgical information and postoperative results were recorded.ResultsAll 12 patients successfully underwent LRT with round ligament suspension and vaginal purse‐string suture, and no conversion to laparotomy was required. The median operation time was 268.5 min (range 200–320 min), including 5 min of round ligament suspension, and the median blood loss was 20 mL (range 5–50 mL). The median number of pelvic lymph nodes removed was 27 (range 19–35), and median amounts of paracervical tissue was 24 mm (range 21–26 mm) and vaginal tissue was 18 mm (range 16–26 mm). No intraoperative complication or serious postoperative complications were reported.ConclusionRound ligament suspension and vaginal purse‐string suture techniques are feasible and effective in LRT. They can replace uterine manipulator and unprotected colpotomy with satisfactory perioperative outcomes.

Current treatment strategies for ovarian cancer in the East Asian Gynecologic Oncology Trial Group (EAGOT)

Ovarian cancer, notable for its severe prognosis among gynecologic cancers, has seen substantial progress in treatment approaches recently. Enhanced protocols in chemotherapy and the introduction of poly (ADP-ribose) polymerase (PARP) inhibitors for maintenance therapy have markedly improved outcomes for patients with specific genetic profiles, such as those positive for BRCA mutations or exhibiting homologous recombination deficiency (HRD). Additionally, the method of intraperitoneal chemotherapy administration has emerged as a valuable alternative to traditional transvenous routes, showing promise for wider clinical adoption. The field of surgery has also evolved, with increasing exploration into the benefits and feasibility of laparoscopic methods over more invasive traditional surgeries, aiming for complete tumor removal but with reduced patient impact. The hereditary nature of ovarian cancer underscores the importance of genetic testing, which has become integral in tailoring treatment strategies, particularly in determining suitability for PARP inhibitors. The formation of the East Asian Gynecologic Oncology Trial Group (EAGOT) aims to optimize treatment across Japan, Korea, China, and Taiwan. The ovarian cancer committee of EAGOT shared the current policies, focusing on 5 topics: 1) strategies for maintenance therapy after initial surgery and chemotherapy, 2) drug regimens for platinum-sensitive and platinum-resistant recurrence, 3) intraperitoneal chemotherapy, 4) laparoscopic surgery as an alternative to laparotomy, and 5) current status of genetic testing (BRCA, HRD, and panel tests) for ovarian cancer and its prospects. EAGOT's multi-national trials aim to harmonize these evolving treatment strategies, ensuring that the latest and most effective protocols are accessible across the region, thereby significantly impacting patient outcomes in East Asia.

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.
