Aims. A single-centre prospective randomized trial was conducted to investigate whether a less intensive follow-up protocol would not be inferior to a conventional follow-up protocol, in terms of overall survival, in patients who have undergone surgery for sarcoma of the limb. Initial short-term results were published in 2014. Patients and Methods. The primary objective was to show non-inferiority of a chest radiograph (CXR) group compared with a CT scan group, and of a less frequent (six-monthly) group than a more frequent (three-monthly) group, in two-by-two comparison. The primary outcome was overall survival and the secondary outcome was a recurrence-free survival. Five-year survival was compared between the CXR and CT scan groups and between the three-monthly and six-monthly groups. Of 500 patients who were enrolled, 476 were available for follow-up. Survival analyses were performed on a per-protocol basis (n = 412). Results. The updated results recorded 12 (2.4%) local recurrences, 182 (36.8%) metastases, and 56 (11.3%) combined (local + metastases) recurrence at a median follow-up of 81 months (60 to 118). Of 68 local recurrences, 60 (88%) were identified by the patients themselves. The six-monthly regime (overall survival (OS) 54%, recurrence-free survival (RFS) 46%) did not lead to a worse survival and was not inferior to the three-monthly regime (OS 55%, RFS 47%) in terms of detecting recurrence. Although CT scans (OS 53%, RFS 54%) detected pulmonary metastasis earlier, it did not lead to a better survival compared with CXR (OS 56%, RFS 59%). Conclusion. The overall survival of patients who are treated for a sarcoma of the limb is not inferior to those followed up with a less intensive regimen than a more intensive protocol, in terms of frequency of visits and mode of imaging. CXR at six-monthly intervals and patient education about examination of the site of the surgery will detect most recurrences without deleterious effects on the eventual outcome.

Aims

Local recurrence remains a challenging and common problem following curettage and joint-sparing surgery for giant cell tumour of bone (GCTB). We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up.

Aims

The existing clinical guidelines do not describe a clear indication for adjuvant radiotherapy (RT) in the treatment of superficial soft tissue sarcomas (STSs). We aimed to determine the efficacy of adjuvant RT for superficial STSs.
