Synovial sarcoma is a rare tumor requiring new treatment methods. A 46-year-old woman with primary monophasic synovial sarcoma in the left thigh involving the sciatic nerve, declining surgery because of potential dysfunction of the affected limbs, received two courses of BNCT. The tumor thus reduced was completely resected with no subsequent recurrence. The patient is now able to walk unassisted, and no local recurrence has been observed, demonstrating the applicability of BNCT as adjuvant therapy for synovial sarcoma. Further study and analysis with more experience accumulation are needed to confirm the real impact of BNCT efficacy for its application to synovial sarcoma.

滑膜肉瘤是一种罕见的肿瘤，需要新的治疗方法。一名 46 岁女性左大腿原发性单相滑膜肉瘤累及坐骨神经，因患肢潜在功能障碍而拒绝手术，接受了两个疗程的 BNCT。如此缩小的肿瘤被完全切除，随后没有复发。患者现在能够独立行走，未观察到局部复发，证明了 BNCT 作为滑膜肉瘤辅助治疗的适用性。需要更多经验积累的进一步研究和分析来证实BNCT疗效对其应用于滑膜肉瘤的真正影响。
