Review of the referral documents of patients with malignant soft tissue tumors

Abstract

Fifteen years have passed since the soft tissue tumor practice guidelines were first published in Japan. Tumor size of ≥ 5 cm and tumor depth were key findings suggestive of malignant soft tissue tumors. We reviewed the referral documents provided by the referring physicians to see if these two findings were reported. The study was conducted from January 2007 to December 2021 and included 142 patients (83 men and 59 women; median age, 64 [6–94] years) with malignant soft tissue tumors. Patient referral documents from physicians were screened for descriptions of the tumor size and depth. The tumor size, depth, and both were described in 51.4%, 36.6%, and 23.2% of the referrals, respectively. Both findings were mentioned in 23.8%, 21.7%, and 25.0% of referrals in 2007–2011, 2012–2016, and 2017–2021, respectively. Of orthopedic surgeons and other physicians, 61.2% and 38.6%, respectively, described the tumor size. Whether the general physicians could follow the soft tissue tumor practice guidelines was difficult to conclude by reviewing patient referral documents. However, orthopedic surgeons seemed to pay more attention to tumor size. Awareness regarding soft tissue tumor practice guidelines should be increased to help diagnose malignant soft tissue tumors early.
