  • Silver-binding nucleolar organizer regions (Ag-NORs)염색법을 이용하여 in vivo 및 in vitro에서 발암과정과 관련된 세포증식능을 검토하였다. A/J마우스에 benzo (a) pyrene을 투여하여 유발된 폐선종, 폐선암 및 Sprague-Dawley랫트에 dimethylbenz (a) anthracene투여에 의해 발생된 유선의 선암세포에서 Ag-NORs의 염색상태를 정상 조직과 비교하여 또한 정상마우스 섬유모세포인 NIH3T3에서의 Ag-NORs의 수 및 DNA 증식 억제물질인 caffeine에 의한 변화를 관찰하였다. 은친화성 NOR과련 단백질은 핵내 흑색의 반점으로 나타났으며 정상 폐조직의 세포당 Ag-NORs 수치는 0.87+0.01였으며 양성종양인 폐선종세포 및 악성종양인 폐선암세포에서는 각각 2.33+0.02, 2.56+0.45 정상 유선조직의 세포당 Ag-NORs수치는 1.21+0.16였으며 악성종양인 선암세포는 3.91+0.11로써 종양성 병변에서 유의한 증가를 보였다 (P<0.005).

  • Between January 1979 and August 1996, resection of a primary chest wall tumor was done in 51 patients. The mean age of the patients was 36.1 years(2 to 69 years). A palpable mass was the most common symptom(32 patients, 62.7%). The tumor was malignant in 11 patients (21.6%) and benign in 40 patients(78.4%). The tumors in 32 patients(62.7%) had developed from the bony or the cartilaginous wall and in 19 patients(37.3%) from soft tissue. Thirty seven of the patients with benign tumors were treated by excision (three of the patients: wide resection and reconstruction) without recurrence or death, and they are currently free from disease. Most malignancies(8 patients) were treated by wide resection and chest wall reconstruction. Five of them are currently alive. The chest wall reconstruction with Marlex mesh, Prolene mesh, or Teflon felt was done in five of the patients with malignant tumors. There was no operative or hospital mortality among the total 51 patients.

  • Purpose: To present our experience with soft tissue reconstruction using anterolateral thigh free flap after resection of soft tissue sarcoma. Materials and Methods: Between January of 2003 and June of 2007, we treated 7 patients with soft tissue reconstruction using anterolateral thigh free flap after wide resection for soft tissue sarcoma. We retrospectively analyzed type and size of tumors, resection margin, size of defect after resection, time of operation, flap survival and complication. Results: The type of sarcoma was 3 synovial sarcoma, 2 malignant fibrous histiocytoma, 1 leimyosarcoma and 1 fibrosarcoma. The size of tumor varied from $3{\times}5\;cm$ to $7{\times}8\;cm$. The resection margins of tumors were negative in all cases. The size of soft tissue defect after resection varied from $6{\times}8\;cm$ to $15{\times}10\;cm$. The mean time of operation was 3.6 hours. All flaps were survived. Conclusion: Anterolateral thigh free flap appear to be ideal for reconstruction after wide resection of soft tissue sarcoma.

  • Purpose To evaluate the incidence and condition of platysma infiltration in benign tumors, malignant tumors, and inflammatory disease in the parotid gland using CT or MRI. Materials and Methods Patients with benign tumors (n = 314), malignant tumors (n = 52), and inflammatory disease (n = 22) in the parotid gland were included. The incidence of platysma infiltration and the relationship between platysma infiltration and the location, capsular involvement, and focality of the mass were retrospectively evaluated using CT or MRI. Results The incidence of platysma infiltration was 0% in benign tumors,19.2% in malignant tumors (10/52), and 50.0% in inflammation (11/22). Platysma infiltration was positive in 10 of 13 patients with inflammatory lesion with capsular involvement. Platysmal infiltrations in inflammatory lesion showed diffuse lesion in 10 patients and focal lesion in one patient. Malignant tumor with platysmal infiltration showed all capsular involvement, and diffuse lesion in seven and focal lesion in three. Conclusion Platysma infiltration was more common in patients with inflammatory disease than those with malignant tumors or benign tumors. In inflammatory disease, platysma infiltration was more common in patients with capsular involvement or diffuse lesion.

  • 장막내의 고립성 섬유성 종양은 드물며 대부분 장측 또는 벽측 흉막에서 발생하지만 종격동, 심막, 복막, 폐실질 , 안과 그리고 뇌척수막에서도 발생하기도 한다. 이 종양은 다양성으로 인하여 진단하는데 어려움이 있으며, 특히 종격동이나 흉부 외의 장소에서 발생하는 경우에는 더욱 그러하다. 이 종양의 임상적 양상을 예측하기 어려우며 조직학적으로 양성의 소견을 보이면서, 임상적으로는 악성의 양상을 띠기도 한다. 악성의 임상양상을 보이는 경우는 약 13∼23% 정도로 보고되고 있다. 저자는 53세의 여자 환자에서 종격동의 고립성 섬유성 조양을 수술한 후, 4차례 재발한 드문 증례를 수술 치험하였기에, 문헌 고찰과 함께 보고하는 바이다.

  • Dedifferentiated chondrosarcoma is a most highly malignant variant of chondrosarcoma and approximately 10% of chondrosarcomas dedifferentiated into more anaplastic lesions. In addition to the surgical treatment, adjuvant chemotherapy or radiation therapy has been used but with little success. Thus, the primary treatment remains wide excision and chemotherapy or radiation therapy can be used for palliation. This article shows the case of a dediffderentiated chondrosarcoma occuring in proximal femur after conservative surgical treatment of a low grade chondrosarcoma.

  • 악성종양의 발생과 진행에 면역 방어기능이 중요한 역할을 하리라는 가설은 모두가 공감하는 사실이다. 이중 T-lymphocyte와 Natural killer cell (이하 NK cell이라함)은 종양 면역학에 특히 중요한 임파구로 이런 임파구의 혈액분포양상은 면역방어기능을 짐작할 수 있는 간접적인 자료가 될 수 있다. 저자들은 치료전 두경부 악성종양환자에서 혈액을 채취하여 T-lymphocyte와NK cell의 분포양상을 검사하고, 방사선치료 환자에서는 NK cell activity를 측정하였기에 다음과 같은 결과를 보고하는 바이다. 1) 두경부 악성 종양 환자군에서 CD3+ cell은 감소하고 NK cell은 증가하며 CD4/CD8 비율은 변화가 없었다. 2) 병변이 진행되면서 CD3+ cell과 CD4+ cell은 감소하고 NK cell은 증가하였으며 CD4/CD8 비율의 변화는 없었다. 3) 방사선치료에 의해 CD3+ cell과 CD4+ cell, CD4/CD8 비율은 감소하였고, NK cell과CD8+cell은 증가하였다. 4) 방사선치료에 의한 CD4/CD8 비율의 감소와, CD8+ cell의 증가는 NK cell의 증가에 의한 것이라 추정되고, NK cell을 제외하면 CB4/CD8 비율의 변화는 없었다. 5) 방사선치료 환자에서 NK cell activity는 증가하였고, 이런 증가가 T-lymphocyte기능의 감소를 보상해 주고 있었다.

  • Benign and malignant bone tumors occur most commonly around the knee. The proximal tibia is the most technically demanding site for limb salvage surgery. The most difficult problem using an endoprothesis for proximal tibial resection has been reconstruction of the extensor mechanism. After excision of proximal tibia, we resected distal femur and made a composite with resected distal femur, low heat treated autogenous proximal tibia and endoprothesis. Patella was fixed into the resected down-loaded distal femur. This article shows the new technique and the results of reconstruction of extensor mechanism after prosthetic replacement of the proximal tibia.
