상지에 발생한 악성 및 침윤성 종양의 분절절제 및 재접합술 = Segmental Resection and Replantation for Primary Malignant or Aggressive Tumors of the Upper Limb

다국어 초록 (Multilingual Abstract)

Object : The aim of the current study is to assess the results of segmental resection and replantation for primary malignant or aggressive tumors of the upper limb. Materials and Methods : From 1986 to 1994, ten patients who had primary malignant or aggressive tumors of the upper limb were managed with segmental resection and replantation method. The average duration of follow-up was 7 years and 7 months. Primary indication of this method is stage II B tumors which, because of their extend, could otherwise be adequately treated only by amputation. Three patients had chondrosarcoma, two had osteosarcoma, two had giant cell tumors with pathologic fracture, one had extensive chondroblastoma, one had Ewings sarcoma, and one had leiomyosarcoma. The location of the tumor was humerus in 6 patients, scapula in 3 patients, and soft tissue of forearm in 1 patient. Wide resection margins were achieved in 7 patients and marginal margin in three. Results : One patient died on 40 months after surgery due to systemic metastasis. Nine patients have remained disease free without local recurrence or metastasis. The average overall functional rating was 65% (43~90%) for ten patients on the last follow-up by the functional rating system of Enneking. The mean grasping power and pinching power of operative hand was 75%(28~95%) and 65%(43~90%) of the opposite hand, respectively. Complications associated with this surgical method included three wound dehiscences and one nerve injury that resolved with proper wound care and time. Conclusion : It was concluded that segmental resection and replantation might be used for partial limb salvage in selected cases for the treatment of primary malignant or aggressive tumors of the upper limb.
