Does Multidisciplinary Therapy at a Sarcoma Center Improve the Prognosis of Patients With Soft Tissue Sarcoma? A Retrospective Case Study at a Single Institute

The effect of multidisciplinary therapy conducted at the sarcoma center of our hospital was examined to determine whether therapy undertaken here improved the prognosis of patients with soft-tissue sarcoma.The clinical findings and prognoses of patients treated before the establishment of the sarcoma center (72 patients from April 2016 to March 2018) and those treated after (155 patients from April 2018 to March 2021) were compared.The mean number of patients increased from 36.0 to 51.7 per year after the establishment of the sarcoma center. The proportion of patients with stage IV disease also increased from 8.3% to 12.9% after establishment of the sarcoma center. The 3-year survival rate of patients, considering all stages, decreased from 80.0% to 78.3% after establishment of the sarcoma center rather than showing an increase. The 3-year survival rate of patients with stage II and III disease increased from 78.6% to 84.7%, and that of stage III patients with retroperitoneal sarcoma increased from 70.0% to 86.7% after establishment of the sarcoma center. However, no statistically significant difference was observed in the survival curves.The establishment of a sarcoma center has contributed to centralizing treatment for soft-tissue sarcoma. Multidisciplinary therapy at sarcoma centers may improve the prognosis of patients with soft-tissue sarcomas.
