Extremity soft tissue sarcoma patient follow-up: tumor grade and size affect surveillance strategies after potentially curative surgery.
A large recent survey disclosed considerable variation in the intensity of follow-up after potentially curative surgery for extremity soft tissue sarcoma among highly credentialed clinicians. The source of the variation is not known. The survey was reanalyzed to investigate whether tumor grade and size account for the variation. The 1,592 members of the Society of Surgical Oncology were surveyed to measure their follow-up practices for 10 years after initial therapy for extremity sarcoma. Repeated-measures analysis of variance was used to measure the relationship among follow-up practice patterns and tumor grade, tumor size, and years after surgery. The 318 respondents who performed surgery and also carried out long-term follow-up for their patients with extremity soft tissue sarcoma were considered evaluable; 94% were general surgeons and 5% were orthopedic surgeons. Office visit, complete blood count, liver function tests, chest X-ray, chest computed tomography, extremity computed tomography, and extremity magnetic resonance imaging were ordered significantly more frequently with increasing tumor grade and size. Tumor grade and size significantly impacted physician practice patterns in post-treatment follow-up, although the degree of variation attributable to these variables was modest. These data permit rational design of a randomized clinical trial of two alternative follow-up plans.
