Evaluating the Impact of Limited Compared With Intense Post-Operative Surveillance on Patient-Reported Outcomes in Patients With Stage II-III Soft Tissue Sarcoma of the Trunk and Extremities

PRIMARY OBJECTIVE: I. To evaluate whether a risk-based limited follow-up surveillance is associated with reduced patient anxiety compared to risk-based intense surveillance. SECONDARY OBJECTIVE: I. To evaluate the impact of reduced surveillance in low-risk patients on overall survival, time to local or distant recurrence, anxiety at early and late time-points, out of pocket costs, and number of missed or extra clinic visits, compared to the risk-based intense follow-up in both low-risk and high-risk patients. OUTLINE: Patients are assigned to 1 of 2 groups based on risk status. GROUP 1 (LOW RISK): Patients are randomized to 1 of 2 arms. ARM I: Patients undergo intense follow-up every 3 months for 2 years consisting of restaging with computed tomography (CT)-chest and imaging of the primary site. ARM II: Patients undergo limited follow-up every 6 months for 2 years consisting of restaging with either CT-chest or chest x-ray (CXR) and imaging of the primary site. GROUP 2 (HIGH RISK): Patients undergo intense follow-up every 3 months for 2 years as in Group 1, Arm I.
