Popis:	Background and Objectives We explored the impact of frequency of surveillance imaging on disease-specific survival (DSS) in patients with extremity soft tissue sarcoma (STS). Methods Locoregional imaging (LRI) and chest imaging (CI) were used to detect local recurrence (LR) and distant metastasis (DM), respectively. Relapsing patients were retrospectively assigned to more frequent surveillance (MFS) or less frequent surveillance (LFS) groups, according to the median interval for each follow-up modality. Outcome measures included overall DSS (O-DSS), post-LR DSS, and post-DM DSS. Results We assigned 165 patients to three distinct risk groups according to tumor size (≤5 vs. >5 cm), depth (superficial- vs. deep-seated), grade (I vs. II or III), and surgical margin (≥10 vs.
