| アブストラクト | BACKGROUND: Pancreatic cancer treatment is evolving, but few studies have examined a nationwide trend in the treatment patterns. The purpose of this study was to clarify real-world treatment patterns for pancreatic cancer in Japan. METHODS: This retrospective study examined the treatment patterns among 68 479 patients, who had pancreatic cancer diagnosis in Medical Data Vision claims database from 2010 to 2018. We extracted relevant data on treatment options, including chemotherapy, surgery and their combination. For patients who had undergone chemotherapy, we sought to analyse the use of different chemotherapy regimens. In addition, we examined the trend in treatment patterns by age group (<59, 60-69, 70-79, >/=80). RESULTS: The trend in treatment options of pancreatic cancer remained stable from 2010 to 2018, with chemotherapy being the most common therapeutic option and surgery performed in approximately half that of chemotherapy. On the other hand, the use of chemotherapy regimen had changed during the same period. Although gemcitabine was the most commonly administrated single-agent regimen in 2010, gemcitabine + nab-paclitaxel was the most frequently used therapeutic agent in 2018. In the older age groups (age >/=80), the majority of patients was untreated (supposedly received supportive care), and the use of conventional regimens such as gemcitabine or S-1 was common among those undergoing chemotherapy. CONCLUSIONS: Although chemotherapy has been the main treatment option for pancreatic cancer, the regimens of choice have increased significantly during the last decade. With accumulating evidence on combination chemotherapy, treatment options may further evolve in the future. |
