Outcomes of Surgery for Benign Tumours in The Upper Extremity.

Abstract

Benign tumours of the upper extremity are common in hand surgeons' practice. The most commonly diagnosed are giant-cell tumours of the tendon sheath and lipomas.

The objective: of this study was an investigation into the distribution of tumours in the upper limb, their symptomatology and outcomes of surgery, particularly regarding the rate of recurrence.

Material and methods: A total of 346 patients, 234 women (68%) and 112 men (32%), who had undergone surgery for tumours located in the upper extremity which were not ganglion cysts were enrolled into the study. The follow-up assessment was performed at a mean of 21 months (range 12-36) post-operatively.

Results: The most common tumour in this study was giant cell tumour of the tendon sheath - 96 cases (27.7%), followed by lipoma - 44 cases (12.7%). Most lesions - 231 (67%) were localized in the digits. A total of 79 (23%) recurrences were noted, the most common after surgery for rheumatoid nodules - 43.3% and the giant-cell tumours of the tendon sheath - 31.3%. The independent factors increasing risk of recurrence following the tumour's resection were: histological type of the lesion - the giant-cell tumour of the tendon sheath (p=0.0086) and the rheumatoid nodule (p=0.0027), as well as a combination of incomplete (non-radical) and not "en block" resection of tumours. A brief review of the literature referring to the presented material is offered.
