Objectives: For patients with advanced ovarian cancer, neoadjuvant chemotherapy (NACT) can significantly increase the rate of optimal cytoreduction. However, this does not translate into a survival benefit. The aim of this study was to investigate the feasibility and effect of neoadjuvant laparoscopic hyperthermic intraperitoneal chemotherapy (NLHIPEC).
Methods: Between March 2016 and February 2018, 14 patients with advanced ovarian cancer who were not candidates for optimal cytoreduction via primary debulking surgery (PDS) received NLHIPEC. Their clinical data were retrospectively analyzed.
Results: No patients experienced intraoperative complications during NLHIPEC. Grade 3 adverse events (AEs) were noted in two (14.3%) patients, and all patients received planned NACT without dose delay or dose reduction. Following NACT, CA125 levels <35 U/mL and <20 U/mL were observed in six (42.9%) patients and five (35.7%) patients, respectively. All patients underwent interval debulking surgery (IDS) after the last NACT cycle. After IDS, R0 resection was achieved in 10 (71.4%) patients without intraoperative injury, and one (7.1%) patient developed a grade 3 AE. During a median follow-up time of 16 months, no patients died of disease, and the median progression-free survival (PFS) was not achieved. Progression was noted in six (42.9%) patients (range, 9–21 months).
Conclusions: NLHIPEC appears to be a feasible option for ovarian cancer patients who have a low likelihood of achieving optimal cytoreduction during PDS.
