ABSTRACT
【Objective】 To retrospectively analyze the average carboplatin dosage and calculate the area under the curve (AUC) using the Calvert formula in first-line chemotherapy in patients with epithelial ovarian cancer in The First Affiliated Hospital of Xi’an Jiaotong University so as to evaluate the effect of the AUC difference in the Chinese population on therapeutic efficacy and safety. 【Methods】 We enrolled patients who underwent first-line chemotherapy with paclitaxel and carboplatin 3-week regimen in our hospital from January 1, 2012 to January 1, 2022. According to the median of AUC, the patients were divided into high-dose group and low-dose group. The overall response rate (ORR), disease control rate (DCR), progression free survival (PFS), overall survival (OS), and the incidence of adverse events (AEs) were compared. 【Results】 A total of 153 patients were enrolled in this study and the median AUC of carboplatin was 3.981 (range 2.314-5.446). Only 10.46% patients (16/153) had an AUC above 5. There were 77 patients with the AUC0.05). The ORR in the low-dose group and the high-dose group was 59.74% and 57.89%, respectively, and the DCR was 87.01% and 85.53%, respectively. The median PFS of the two groups was 14 and 15.5 months, respectively, and the median OS was 50 and 55 months, respectively. None of the above outcomes were statistically different between the two groups (P>0.05). The two groups showed significant differences in the incidence of anemia, neutropenia, and thrombocytopenia (P<0.05). The incidence of nausea and vomiting, grade 1-2 diarrhea or constipation, and grade 1-2 fever showed significant differences (P<0.05). In addition, the incidence of dose limiting toxicity (DLT), including grade 4 thrombocytopenia and febrile neutropenia (FN), was significantly increased in the high-dose group (P<0.05). 【Conclusion】 Compared with the recommended AUC 5-6 of carboplatin abroad, the actual carboplatin dosage in the first-line chemotherapy for patients with epithelial ovarian cancer was generally insufficient in our hospital. There was no difference in therapeutic efficacy between the patients with AUC<4 and AUC≥4. However, considering the increased risk of some AEs and DLT in the high-dose group, it is not recommended to increase the carboplatin AUC blindly.
