Does biopsy before excision have contribution to clinical results in patients with schwannoma? A single-center prospective observational study

Abstract

Introduction: This study aimed to investigate whether tru-cut biopsy before excision contributes to clinical outcomes in patients diagnosed with limb schwannoma.Materials and methods: Tru-cut biopsy was performed before excision in patients diagnosed with schwannoma of the extremity in clinical and radiological evaluations. All patients underwent total excision with microsurgical methods. Demographic data, complications of tru-cut biopsy, treatments, and clinical results were analyzed.Results: Data for 17 patients (9 males and 8 females) were analyzed. The mean age was 49.8 years. No complications related to tru-cut biopsy were observed. The mean preoperative and postoperative VAS scores were 4.3 and 0.4, respectively. One patient developed postoperative neurological complications. No recurrence was observed in any patient.Conclusions: In schwannomas of the extremities, tru-cut biopsy before excision is an applicable and reliable option. The preoperative diagnosis is ascertained as schwannoma, and the outcomes of making the excision with microsurgical techniques are quite good.
