초록

목적: 골육종 치료에 있어서 사지 구제술이 보편화되었다. 이 중 수술 수기가 간편하고, 기능적인 회복이 빠른 종양 대치물을 재건 방법으로 사용하고 있을 뿐만 아니라, 다른 생물학적 구제술이나 관절 고정술 등의 합병증으로 인하여 이차적으로 종양 대치술을 사용되고 있다. 본 연구는 광범위 절제술 이후, 일차적으로 종양 대치술을 시행하는 방법의 장기 추시상 결과를 환자 및 종양 대치물의 생존, 기능적 결과, 합병증 측면에서 보고하고자 한다. 대상 및 방법: 1989년 2월부터 2006년 12월까지 본원에서 골육종으로 진단받은 158예 중, 5년 이상 추시관찰이 가능하고 일차적으로 종양 대치물을 이용한 재건술을 시행하였던 48예를 대상으로 하였다. 추시 기간은 최소 60개월에서 최대 179개월이었다. 남자 28예, 여자 20예 였으며, 평균 나이는 22.4 (11-71세)였다. 병리학적 분류상 전형적인 중심성 골육종 46예, 골막성 2예이었다. 골육종 부위는 근위 경골 26예, 원위 대퇴골 20예, 대퇴골 간부, 경골 간부 각 1예이었다. 종양 대치물의 종류는 41예에서 조립형 종양 대치물을, 7예에서는 확장형 종양 대치물을 이용하여 재건술을 시행하였다. 술 후 기능적 평가를 위해 Musculoskeletal Tumor Society (MSTS) Grading System을 이용하였으며, 환자 및 종양 대치물의 생존율, 합병증에 대해 분석하였다. 결과: 환자의 5년 전체 생존율은 77.7%이었고, 5년 무병 생존율은 68.9%이었다. 종양 대치물의 생존율은 68%이었다. 일차적 치환술을 시행한 48예 중 총 20예에서 합병증이 발생하였으며, 감염이 10예로 가장 많았다. 수술적 치료 술 후 MSTS 기능적 평가는 74.1%이었다. 결론: 일차적 종양 대치술의 장기 추시 결과상 골종양 절제 후 재건 방법으로 생존율, 기능적 평가 및 합병증 측면에서 효과적인 방법이라고 사료된다.

Purpose: Modular tumor prosthesis is the most popular recontructive modality after resection of malignat tumor in extremity. Complications and survival of tumor prosthesis reconstruction are well-known. however, reports on the long-term outcome of tumor prosthesis in osteosarcoma patientss are scarece. Materials and Methods: In 158 cases as diagnosed as osteosarcoma from feburary 1989 to December 2006 in a single cancer center. We retrospectively reviewd 48 osteosarcoma patients who under went tumor prosthetic reconstruction. Mean follow up preiod was 75.6 months (range; 60 to 179 months). There were 28 males, 20 females and mean age was 22.4 years (range; 11-71). Pathologic subtypes were conventional central osteosarcoma in 46 cases and periosteal in 2 cases. The location of the tumor was proximal tibia (26 cases), distal femor (20 cases), femor diaphysis (1 case), and tibia diaphysis (1 case). In 41 cases built-up-type tumor prosthesis have been used and 7 cases expansion-type tumor prosthesis have been used. We used Musculoskeletal tumor society (MSTS) grading system to asses post operation function, and we analyzed survival rate of patient and tumor prosthesis and complication. Results: The overall survival rate was 77.7% and disease free survival rate was 68.9%. The survival rate of tumor prosthesis was 73%, in last follow up tumor prosthesis has been removed in 12 cases. All of them, 17 complications occurred, which included infection in 16 cases, Periprosthetic Fracture and Loosening of tumor prosthesis in 4 cases, articular instability in 4 cases. MSTS functional score was 74.1% in post operation. Conclusion: In long term follow up result, Primary tumor prosthesis -a reconstruction method after a wide extensional resecion of a bone tumor- can be a effective treatment method in asepect of survival rate, functional assesment and complication.
