Postoperative radiotherapy for pigmented villonodular synovitis (PVNS): case series and literature review

Abstract

Abstract Purpose: Pigmented villonodular synovitis (PVNS) is a rare benign proliferative disease of the synovium with locally aggressive behaviour. We reviewed our experience using external beam radiotherapy (RT) in the treatment of PVNS. Method: We report five cases of PVNS who underwent Arthroscopic Synovectomy followed by postoperative RT in National Oncology centre in Oman. The total dose RT ranges between 30 and 36 Gray (Gy) Three-dimensional radiotherapy technique. Conclusion: Postoperative RT is effective in preventing disease recurrence and should be offered following maximal cytoreduction to enhance local control in PVNS.
