좌측 대퇴골 원위부 골육종 진단 받은 9세 여아로 광범위 절제수술과 재활용 자가골 이식술을 받은 후 하지 부동과 성장판 손상이 있어 확장형 종양 대치물로 치환수술을 시행하였다. 그 후 종양 대치물에 심부 감염 발생하여 종양 대치물 제거 후 감염을 조절하기 위한 시멘트와 골수내정을 이용한 한시적 공간 대치물을 삽입하였다. 감염이 조절된 후 외고정 장치를 이용한 하지 부동(10 cm)에 대한 교정을 시행하였고, 마지막으로 종양 대치물 재삽입을 통한 관절 기능 보존을 시행한 1례를 보고 하고자 한다. In 1996, a nine-year-old girl was treated with recycling autograft after wide resection of the distal femoral osteosarcoma. The leg lengthening and revision with growing tumor prosthesis were performed due to limb leg discrepancy and epiphyseal problem. However, deep infection developed after operation, and a temporary spacer with cement and Ender nail was inserted. After infection was controlled completely, the final leg lengthening was performed with mono-external fixator for limb length discrepancy (10 cm). Lastly, Tumor prosthesis was reinserted to preserve the joint function.

목적: 악성 흑색종의 치료 중 가장 중요한 것은 외과적 전절제술이며, 수술시 광범위 절제술을 시행한다. 저자 등은 광범위절제와 면역화학요법을 시행한 후 각 병기별 5년 생존율을 알아보고 예후에 영향을 주는 요인을 주는 요인들을 분석하고자 한다. 대상 및 방법: 1995년 3월부터 2003년 8월까지 악성 흑색종으로 진단 받았던 35명(남자 17명, 여자 18명)을 대상으로 광범위절제술과 면역화학요법을 시행한 후 추시 관찰하였다. 절제술은 종양의 크기나 피부층의 침범정도와 상관없이 종양의 변연으로부터 2 cm으로 하였고, 절제술 후 덮이지 않는 피부 결손부는 피판 이식술이나 전층 피부 이식술을 이용하였다, 면역화학요법으로는 dacarbazine (DTIC) 400 mg과 인터페론-${\alpha}$ 300만 IU를 병용 투여 하는 방법을 사용하였다. 면역화학요법은 III기 이상의 환자에게 시행하였고, 병기는 2002년 개정된 AJCC 병기를 이용하여 판정하였다. 또 이들 환자들에 대해 국소재발과 국소전이, 그리고 원격전이여부를 조사하였고, 각 병기별 5년 생존율을 조사하였다. 결과: 발생부위는 족부가 15명(42.8%)으로 가장 많았고, 족관절부 5명(14.2%), 하퇴부 2명(5.7%), 대퇴부 2명(5.7%), 수부에 5명(14.2%)이었다. 병기별 발생빈도는 IA 8명(22.8%), IB 9명(25.7%), IIA 4명(11.4%), IIB 2명(5.7%), IIIA 1명(2.8%), IIIB 2명(5.7%), IIIC 2명(5.7%) 그리고 IV기는 7명(20.0%) 이었다. 각 병기별 5년 생존율은 I기에서 94.1%, II기에서 66.8%, III기에서 40%, IV기에서 14.3%로 나타났다. 결론: 악성 흑색종은 III기 이상에서는 5년 생존율이 낮았다. 악성 흑색종의 치료는 초기에 진단하여 병기에 따라 치료의 방법을 달리하므로 수술전 병기의 확인이 매우 중요하다. 광범위 절제연에 대해서는 종양 두께에 따라 1~3 cm의 절제연으로 광범위 절제를 권유한다. Purpose: The most important thing in curing Malignant melanoma is surgical excision, operating method is wide excision. The author et al. studied 5-year survival rate of each stage and appropriate surgical margin after operating wide excision and immuno-chemotherapy. Materials and methods: From March 1995 to August 2003, wide excision and immunochemotherapy were operated to 35 patients (17 males and 18 females) who were diagnosed as malignant melanoma and followed up. Excision was done around 2 cm from edge of tumor regardless of the size or effected degree of the skin, and flap or full thickness skin graft was used for skin deficit that was not covered after excision. As for immuno-chemotherapy, method that prescribes 400 mg of dacarbazine (DTIC) and 3 million IU of interferone-${\alpha}$ in combination was used. Immuno-chemotherapy was operated to patients in over stage III. We used AJCC stage that was revised in 2002. Local recurrence, local metastasis and distant metastasis were investigated for these patients as well as the 5-year survival rate of each stage. Results: Most frequently 15 cases(42.8%) occurred in foot, 5 cases(14.2%) occured in ankle, 2 cases(5.7%) in leg, 2 cases(5.7%) in thigh and 5 cases(14.2%) in hand. The incidence of each stage were 8 cases(22.8%) in IA, 9 cases(25.7 %) in IB, 4 cases(11.4%) in IIA, 2 cases(5.7%) in IIB, 1 cases(2.8%) in IIIA, 2 cases(5.7%) in IIIB, 2 cases(5.7%) in IIIC and 7 cases(20.0%) in stage IV. 5-year survival rate of each stage were 94.1% in stage I, 66.8% in stage II, 40% in stage III and 14.3% in stage IV. Conclusion: 5-year survival rate of stage IV was low in malignant melanoma. In treatment of malignant melanoma, staging before operation is important as operation methods are different from each stage. We recommend wide excision which remove around 1~3 cm from margin of tumor up to each thickness.

권영호,조영율,김재도,정소학,Kwon, Young-Ho,Cho, Yool,Kim, Jae-Do,Chung, So-Hak 대한근골격종양학회 2008 대한골관절종양학회지 Vol.14 No.1

목적: 족관절 및 족부에 발생한 악성 연부 조직 종양의 광범위 절제술 후 시행한 재건술의 임상적 효용성에 대하여 알아보고자 한다. 대상 및 방법: 2000년 3월에서 2007년 3월까지 족관절 및 족부에 악성 연부 조직 종양이 발생하여 광범위 절제술을 시행한 후 재건술을 시행한 15례(14명)을 대상으로 하였다. 폐 전이로 사망한 1례를 제외하고 평균 36.4개월(7~72개월)의 추시기간을 가졌고, 평균 연령은 56.8세(26~77세), 남자가 11명, 여자가 3명이었다. 원발병소는 악성 흑색종 12례, 편평상피 세포암 3례이었다. 최종 추시점에서 종양학적, 수술적 그리고 기능적인 결과를 비교하였다. 결과: 재건술의 방법은 전외측 대퇴부 천공지 피판 5례, 역행성 표재 비복동맥 피판 4례, 족배 동맥 피판 3례와 국소 피판 3례였다. 결손의 크기는 평균 $5.5{\times}5.7\;cm$, 피판의 크기는 평균 $5.9{\times}6.0\;cm$이었다. 회전 피판술 결손의 크기는 평균 $4.6{\times}4.7\;cm$, 피판의 크기는 평균 $4.9{\times}4.8\;cm$이었고 유리 피판술 결손의 크기는 평균 $7.2{\times}7.8\;cm$, 피판의 크기는 평균 $8.2{\times}8.8\;cm$이었다. 평균 수술 시간은 310분(120~540분)이었고, 회전 피판술은 256분, 유리 피판술은 420분이었다. 1례가 폐전이로 사망하였고 국소 재발한 4례와 원격 전이가 발견된 4례를 제외한 7례에서는 최종 추시상 병변이 발견되지 않았다. 피판의 국소적인 울혈외에 수술적 합병증은 없었고, 술 후 MSTS 점수는 평균 68.8%였다. 결론: 족관절 및 족부에 발생한 악성 연부 조직 종양의 광범위 절제술 후 결손의 크기가 비교적 작을 경우($5{\times}5\;cm$ 이하)인 경우 족배 동맥 피판술, 역행성 표재 비복 동맥 피판술과 같은 회전 피판술을 일차적으로 고려해 볼 수 있다. 결손이 더 크거나 복합 조직이 필요한 경우 전외측 대퇴부 천공지 피판술을 포함한 유리 피판술이 더 유용할 것으로 사료된다. 그리고 악성 흑색종의 경우 재건 방법은 종양학적인 결과에 영향을 미치지 않는 것으로 보인다. Purpose: To evaluate the clinical usability of reconstructive methods, and how to select flap after wide excision of malignant soft tissue tumor in ankle and foot. Materials and Methods: The 15 cases shown in the 14 patients (In case of a male patient, reconstruction was performed two times due to local recurrence.) with malignant soft tissue tumor in ankle and foot, who underwent reconstruction after wide excision from March 2000 until March 2007. Oncologic, surgical and functional results were evaluated. Results: The method of reconstruction used were anterolateral thigh perforator flap (5cases), Reversed superficial sural artery flap (4 cases), dorsalis pedis flap (3 cases), local flap (3cases). The defect, mean size was $5.5{\times}5.7\;cm$, was reconstructed with rotation flap or free flap, mean size was $5.9{\times}6.0\;cm$, skin graft for remnant. The mean operation time was 310 minutes (120~540 minutes); it took 256 minutes to reconstruct by rotation flap, and 420 minutes by free flap. As oncologic results, 7 patients were no evidence of disease, 6 patients were alive with disease and 1 patient was expired by pulmonary metastasis at the time of the last follow-up. 4 patients had local recurrence and 4 pateints had distant metastases. As functional results, 14 patients were evaluated with average score of 68.8% using the system of the Musculoskeletal Tumor Society. Conclusion: The dorsalis pedis and reverse superficial sural artery rotation flap which is easy procedure, has less complication and takes short operation time, can be primarily considered to reconstruct a small defect. And the anterolateral thigh perforator flap is suitable for coverage of a large defects after wide excision of malignant soft tissue tumor in ankle and foot.

Purpose: The purpose of this study was to evaluate the clinical results of anterolateral thigh free flap on soft tissue defect following wide excision in malignant soft tissue tumor of lower extremities. Methods: Between February 2005 to April 2010, we followed up 19 cases who were undergoing anterolateral thigh free flap because of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity, including 9 cases were heel, 5 cases in foot, 3 cases in ankle, 2 cases in knee and leg. We observed that of implanted area's color, peripheral circulation at 3, 5, 7 days after operation and evaluated operating time, amount of hemorrhage, implanted skin necrosis, additional operations, complications. And we also evaluated the oncologic results, including local recurrence, metastasis, and morbidity. Results: Average operation time of wide excision and anterolateral thigh free flap was 7 hour 28 minutes. 18(94.7%) of total 19 cases showed successful engraftment, on the other hand, failure of engraftment due to complete necrosis of flap in 1 case. In 18 cases with successful engraftment, reoperation was performed in 4 cases. Among them, removal of hematoma and engraftment of flap after bleeding control was performed in 3 cases, because of insufficient circulation due to the hematoma. In the remaining 1 case, graft necrosis due to flap infection was checked, and grafted after combination of wound debridement and conservative treatment such as antibiotics therapy, also skin graft was performed at debrided skin defect area. Skin color change was mainly due to congestion with hematoma, flap was not observed global congestion or necrosis except 4 cases which shows partial necrosis on margin that treated with conservative therapy. Conclusions: Anterolateral thigh free flap could be recommended for reconstruction of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity.

낙동강 중. 하류에서의 규조류 성장잠재력 평가

권영호,서정관,박상원,양상용,Kwon, Young-Ho,Seo, Jung-Kwan,Park, Sang-Won,Yang, Sang-Yong 한국조류학회(藻類) 2006 ALGAE Vol.21 No.2

For the test organism of algal growth potential (AGP), the diatom in the genus Stephanodiscus which cause blooms in the Nakdong River was used instead of generally used strains of Selenastrum, Microcystis, or Anabaena. AGP results indicated that all the samples in the Nakdong River except for that from the Nakdan Bridge site were eutrophic state. Furthermore, the sample from Kumho River site was hypertrophic state. In the main stream Nakdong River, the value of AGP was lowest at the upstream Nakdan Bridge site and was highest at Koryoung Bridge site which is just downstream of Kumho River confluent point indicating the seriousness of pollution contributed by the Kumho River to the Nakdong River. Changes in the concentration of nutrients before and after the AGP tests and inter-relationship among the nutrients indicated that the growth of the Stephanodiscus in the AGP tests were mostly affected by the nitrate, silicate and phosphate. The limiting nutrient was identified by the nutrient addition experiments and the results showed that phosphate was the limiting nutrient for the growth of Stephanodiscus in the tested samples.

Purpose: Evaluation of results of free flap as a method of reconstruction in soft tissue defect after wide excision of soft tissue tumor of extremity. Materials and Methods: From 2000 through 2007, 11 patients received free flap surgery for soft tissue defect after wide excision operation for soft tissue tumor of limbs. Four cases were upper extremities and seven were lower extremities. Four subjects were diagnosed as squamous cell carcinoma, three as malignant melanoma, two as synovial sarcoma and one as malignant fibrous histiocytoma and alveolar soft part sarcoma. Donor sites of free flap varied with anterolateral thigh flaps in six cases, latissimus dorsi flaps in four, reverse forearm flap in one. By the method of doppler ultrasound, venous circulation was evaluated for the survival of each flap on the third, fifth and seventh day respectively after the operation. Results: 10 of 11 free flaps were successfully survived. Necrosis of free flaps in 1 cases occurred in case of anterolateral thigh flap. Conclusion: Free flap can be a useful method for reconstruction of soft tissue defect after wide excision of soft tissue sarcoma of extremity.
