Abstract

Gemcitabine plus cisplatin (GC) is the standard first line of chemotherapy for urothelial carcinoma. However, it is often difficult to complete scheduled GC therapy because of real‑world adverse events. Therefore, the reasons behind delays, scheduled cancelations and determined predictive factors for completing scheduled GC therapy were retrospectively analyzed. Patients diagnosed with locally advanced or metastatic urothelial carcinoma from 2009 to 2020 received a 4‑week GC therapy schedule in Oita University Hospital. Information was retrospectively extracted from medical records and all cycles were divided into two groups: One wherein all treatments were administered and completed on schedule and the other wherein treatment was either delayed or canceled in during the treatment schedule. Predictive factors were then statistically extracted between the two groups. In total, 70 patients received 201 cycles of a 4‑week scheduled GC therapy. Of the 201 cycles, a total of 68 (33.8%) completed all scheduled treatments, while 133 (66.1%) did not complete the treatment as scheduled. In the group where administration was not completed on schedule, the factors of male, ureteral cancer, lower stage, <90% of gemcitabine and cisplatin dosage, solitary kidney, high creatinine level, low estimated glomerular filtration rate level, low platelet count and high alkaline phosphatase level at the initiation of each cycle were more significant. Additionally, the lowest anticancer drug percentage administration was on day 15. From these results, predictive factors for patients with various backgrounds who completed the scheduled 4‑week GC therapy based on real‑world data were identified. This information can be useful for clinical physicians when deciding the course of treatment.
