- W4387408908 abstract "Abstract Objectives To investigate temporal trends in treatment patterns and prognostic factors for overall survival in patients with metastatic biliary tract cancer. Methods From the Tokushukai REAl-world Data project, we identified 945 patients with metastatic biliary tract cancer treated with gemcitabine, tegafur/gimeracil/oteracil, gemcitabine plus cisplatin, gemcitabine plus tegafur/gimeracil/oteracil or gemcitabine plus cisplatin and tegafur/gimeracil/oteracil between April 2010 and March 2022. Stratified/conventional Cox regression analyses were conducted to examine the association between overall survival and patient- and tumour-related factors, study period, hospital volume, hospital type and first-line chemotherapy regimen. Using inverse probability of treatment weighting with propensity scores, overall survival was also compared between monotherapy and combination therapy groups. Results We enrolled 366 patients (199 men; median age, 72 years). Over a median follow-up of 5.2 months, the median overall survival was 7.0 months (95% confidence interval 6.2–9.0), and the median time to treatment failure was 3.5 months (95% confidence interval 3.1–4.5). Median overall survival and time to treatment failure for gemcitabine/tegafur–gimeracil–oteracil/gemcitabine plus cisplatin/gemcitabine plus tegafur–gimeracil–oteracil/gemcitabine plus cisplatin and tegafur–gimeracil–oteracil regimen were 6.2/6.6/7.9/16.2/15.1 and 2.8/3.4/4.1/15.3/7.4 months, respectively. Primary disease site, previous surgery, previous endoscopic procedures and hospital type were identified as significant prognostic factors. Inverse probability of treatment weighting analysis demonstrated that combination therapy had a significantly better prognosis than monotherapy (hazard ratio 0.61, 95% confidence interval 0.43–0.88, P = 0.006). Conclusions Our real-world data analysis showed that standard care for metastatic biliary tract cancer is widely used in hospitals throughout Japan and verified the survival benefits of combination therapy over monotherapy observed in prior clinical trials. Clinical trial number UMIN000050590 (http://www.umin.ac.jp/ctr/index.htm)." @default.
