There are currently no studies demonstrating the effects of palonosetron on delayed chemotherapy-induced nausea and vomiting (CINV) in gynecological cancer patients receiving chemotherapy with moderately emetogenic chemotherapeutic agents. We conducted a phase II clinical trial to assess the efficacy and safety of palonosetron in patients receiving paclitaxel/carboplatin (TC) therapy. The study population consisted of 42 patients who had been diagnosed with gynecological malignancies and treated with TC. On day 1, 0.75 mg/body palonosetron and 19.8 mg/body dexamethasone were administered intravenously immediately prior to TC therapy. Dexamethasone in daily doses of 6.6 mg/body was also administered intravenously on days 2 and 3. The efficacy and safety of palonosetron + dexamethasone were evaluated by the self-completion method using the Multinational Association of Supportive Care in Cancer Antiemesis Tool during an observation period lasting from day 1 through day 8 of the initial cycle of TC therapy. The severity of the nausea was assessed using a visual analog scale. During the acute (0-24 h), delayed (24-96 h) and overall (0-96 h) periods, the complete response rates were 95.2, 90.5 and 85.7%, respectively, whereas the complete control rates were 90.5, 85.7 and 78.6%, respectively. Grade ≥ 2 constipation and diarrhea developed in 1 patient (2.4%) each. The palonosetron + dexamethasone regimen proved to be effective for delayed CINV in gynecological cancer patients receiving TC therapy. This combined antiemetic regimen was associated with only mild adverse reactions and may serve as supportive therapy, allowing cancer chemotherapy to be continued while maintaining an adequate quality of life.
