목적: 원발 성 악성 골반부 종양의 수술적 치료에 관한 기능적, 종양적 결과와 그에 따른 합병증을 분석 하고자 한다. 대상 및 방법: 1994년 12월부터 2004년 5월까지 골반부 종양에 대해 수술을 받은 21명의 환자(남자 10, 여자 11)를 대상으로 후향적으로 조사하였다. 평균 연령은 39.1세였으며, 평균 추시 관찰 기간은 27.9개월이었다. 병리학적 진단은 연골 육종 10예, 골육종 6예, 골수종과 유잉 육종이 각각 2예, 지방 육종이 1예였다. 병변은 장골에 10예, 비구에 4예, 치골에 7예가 위치해 있었다. 수술은 광범위 절제술로 7예, 광범위 절제술과 체외 방사선 골이식술로 9예, 광범위 절제술과 Pasteurization으로 3예, 광범위 절제술과 인공 대치물 삽입술이 2예로 시행하였다. Musculoskeletal Tumor Society (MSTS) 기능평가 지수(1993년)와 합병증, 종양적 결과를 조사하였다. 결과: 평균 MSTS 기능 평가 지수는 72.3%였다(환자의 사망으로 인한 골육종 4예, 연골 육종 2예, 골수종 및 지방육종 1예를 제외). 장골의 기능 평가 지수는 76.2%, 비구는 61.7%, 치골 70.0%였다. 연골 육종의 평가 지수는 72.5%, 골육종은 75.0%, 골수종 73.3%, 유잉 육종 68.3%였다. 종양학적 결과에 의하면 NED (alive with no evidence of disease)는 11예, AWD (alive with disease)는 2예, DOC (died of other cause)는 2예, DOD (died of disease)는 6예였다. 합병증으로는 국소적 재발이 3예, 심부 감염이 2예, 그리고 피부 결손이 1예였다. 결론: 골반부 종양의 수술적 치료는 기술적 어려움과 합병증에도 불고하고 보다 낳은 기능적, 종양학적 결과를 고려해 볼 때 효과적인 선택적 방법이다.
Purpose: To analyze the functional and oncologic outcomes and the possible complications involved in the surgical treatment of primary malignant pelvic tumors. Materials and Methods: 21 patients (10 males, 11 females) with pelvic tumors who received surgical treatment from December 1994 to May 2004 were studied retrospectively. The mean age was 39.1 years (ranging from 5 to 69 years) and the mean follow-up period was 27.9 months (ranging from 10 to 68 months). Pathologic diagnoses included 10 cases of chondrosarcoma, 6 cases of osteosarcoma, 2 cases each of myeloma and Ewing's sarcoma, and 1 case of liposarcoma. The pelvic lesions were located in 3 places; there were 10 cases in the ilium, 4 in the acetabulum, and 7 in the ischium. Seven patients had wide excision only, 9 had wide excision with intraoperative radiated bone graft (IORBG), 3 had wide excision with Pasteurization, and 2 patients had wide excision with prosthesis. We evaluated functional outcomes as described by the Musculoskeletal Tumor Society (MSTS) score (1993) and investigated complications and oncologic results. Results: The Average MSTS score was 72.3% (4 cases of osteosarcoma, 2 cases of chondrosarcoma, 1 case each of myeloma and liposarcoma were excluded due to mortality). The MSTS score of the ilium lesion was 76.2%, the acetabulum 61.7%, and the ischium 70.0%. The MSTS score of the chondrosarcoma was 72.5%, the osteosarcoma 75.0%, the myeloma 73.3%, and Ewing's sarcoma 68.3%. As evaluated by onlcologic results, 11 patients were NED (alive with no evidence of disease), 2 were AWD (alive with disease), 2 were DOC (died of other causes), and 6 were DOD (died of disease). Complications occurred in 6 cases; 3 cases of local recurrence, 2 cases of deep infection and 1 case of skin defects. Conclusion: Surgical treatment of a pelvic tumor is an effective optional management for better functional and oncologic results in spite of the technical difficulties and considerable complications.
