卵巣がんに対するPegylated Liposomal Doxorubicin療法による手足症候群発現に及ぼす影響因子の解析

Abstract

Pegylated liposomal doxorubicin (PLD) is a liposomal formulation of doxorubicin hydrochloride. It was approved for the treatment of ovarian cancer aggravated after chemotherapy. The occurrence of hand-foot syndrome (HFS) associated with the administration of PLD is considered one of the major adverse side effects. The development of Grade2 ≦ HFS (Serious HFS) during the course of PLD therapy calls for dose reduction or discontinuation of subsequent PLD administration. However, the factors that influence the development of HFS are unclear in Japan. Therefore, we focused on the factors influencing the development of HFS in patients receiving PLD therapy for ovarian cancer. The study population consisted of 36 patients. Twenty patients (55.6%) developed HFS while 10 patients (27.8%) developed serious HFS. The patients who did not develop stomatitis during PLD therapy, also never developed serious HFS. In contrast, 37.0% (10/27) of the patients who had developed stomatitis during PLD therapy were reported to have developed serious HFS (P = 0.0390). For the 10 patients with serious HFS, the median time for the occurrence of serious HFS and stomatitis after the initiation of PLD therapy was 3 cycles and 1 cycle, respectively. In conclusion, patients who developed stomatitis during the course of PLD therapy were more likely to develop serious HFS than those who did not. Additionally, stomatitis has been reported to develop prior to serious HFS. Therefore, the occurrence of stomatitis during PLD therapy can aid in the prediction of serious HFS development in future.
