Background
The surgical treatment for retroperitoneal sarcoma (RPS) is challenging because of its complex clinical features. According to the Japanese National Health-Care Insurance System, the fee for the surgical treatment of RPS is nearly equal to that of open distal gastrectomy for gastric cancer (GC). The purpose of the present study is to compare the financial burdens of surgery for RPS and 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 fee per surgeon and surgical fee per hour were compared between the two groups.
Results
There were 35 patients in the GC group and 63 patients in the RPS group. In the latter, 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 operation 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 1,667 dollars in the GC group and 1,022 dollars in the RPS group (p < 0.001); that per hour was 1,388 dollars and 777 dollars, respectively (p < 0.001).
Conclusions
The financial burden of surgical treatment for RPS was unexpectedly higher than that for GC. Additional data are needed to determine the actual costs of RPS treatment and to justify the fee for the surgical treatment of RPS.
