Financial burden of surgical treatment for retroperitoneal sarcoma.

ABSTRACT

PURPOSES: The purpose of this study was to compare the financial burden of surgery for retroperitoneal sarcoma (RPS) and gastric cancer (GC). METHODS: All patients who underwent surgery for GC or RPS between 2020 and 2021 at Nagoya University Hospital were included. The clinical characteristics, surgical fees per surgeon, and surgical fees per hour were compared between the two groups. RESULTS: The GC and RPS groups included 35 and 63 patients, respectively. In the latter group, 37 patients (59%) underwent tumor resection combined with organ resection; the most common organ was the intestine (n = 23, 37%), followed by the kidney (n = 16, 25%). The mean operative time (248 vs. 417 min, p < 0.001) and intraoperative blood loss (423 vs. 1123 ml, p < 0.001) were significantly greater in the RPS group than in the GC group. The mean surgical fee per surgeon was USD 1667 in the GC group and USD 1022 in the RPS group (p < 0.001) and USD 1388 and USD 777 per hour, respectively (p < 0.001). CONCLUSIONS: The financial burden of surgical treatment for RPS is unexpectedly higher than that for GC.
