기관 및 기관지 종양은 대부분이 악성 종양이며 양성 종양은 10% 이내에 불과하다. 특히 폐에 발생하는 원발성 신경성 종양은 전체 폐종양의 2% 이하로 대부분이 Schwann세포에서 기원한다고 알려져 있다. 이러한 종양은 주로 고립성 양성 종양으로 나타나며 드문 경우에 악성의 형태를 보이기도 한다. 기관지내 신경초종은 폐의 원발성 종양 중에서 발생빈도가 매우 낮은 것으로 알려져 있다. 저자들은 기관지내 신경초종으로 폐엽절제술을 시행한 2예를 보고하는 바이다.

From May 1965 to December 1990, 78 patients with chest wall tumors were operated on. The mean age of the patients was 31.5 years with 50 male and 28 female patients. Forty-nine cases[62.8%] were developed at bony or cartilaginous wall and 29 cases[37.2%] at soft tissue of chest wall. Thirty-two of them[41.0%] were malignant, either primary or metastatic, and 46 tumors[59.0%] were histologically benign. For 55 patients who were operated on since 1982, 6 surgical biopsies. 39 tumor excisions, and 11 wide excisions with chest wall reconstruction were done. Preoperative factors favoring diagnosis of malignant neoplasm were; 1] old-aged male patient, 2] bone or cartilaginous tumors, 3] involvement of multiple ribs, 4] complaint of pain, 5] large size on palpation[larger than 4cm]. With proper diagnosis and management plan, we think, operations of chest wall tumors can give good results.

Salivary gland tumors usually appear in solitary mass in single salivary gland. The coexistence of tumors with different histological types occurring within a unilateral parotid gland is an extremely rare event. We experienced a case which two different types of malignant tumors developed at different time points in same gland; metachronous tumors. The second tumor was excised widely and reconstruction was performed by free tissue transfer. Sensory and motor nerve to the left cheek appeared to be intact, and circulation was adequate. This rare case was presented in this article.

Tumors of the parotid gland are the most frequently encountered salivary gland tumors. Knowledge of the histology and anatomy of the salivary gland is important when considering the histiogenesis of salivary gland tumors, requiring close cooperation between the pathologist and the surgeon. Most tumors are benign epithelial formations. Pleomorphic adenomas predominate. Superficial lobectomy is adequate treatment. When the tumor involves a deep lobe, total parotidectomy is indicated. Treatment of malignant tumors depends on the histology, its TNM stage and other factors. Total parotidectomy with lymph adectomy and radiotherapy are needed in case of high grade malignancy. In children, vascular neoplasias are the most frequent, followed by malignant tumors. Their histological features and treatment are the same as for adults. We reviewed 64 cases of the parotid tumors at Department of surgery, Dong-A University Hospital from July. 1990 to Jan. 1999 for the purpose of apprehension of parotid gland tumor by the clinical study and review. Over all sex ratio was 1：1.13(M:F), mean age was 38.9 years, mean size was 3.53cm. According to histologic findings of 64 cases, pleomorphic adenoma was 55(85.9%), Warthin's tumor was 3(4.7%), mucoepidermoid carcinoma was 3(4.7%), squamous cell carcinoma was 2(3.1%), acinic cell carcinoma was 1(1,6%). Post op. facial nerve palsy 16(25%), Frey's syndrome 11(17.2%) cases were happened. Hence, the clinical manifestation of pain, tenderness, facial N. palsy suggest malignant tumors.

Backgroud and Objectives: Major salivary gland tumor is a rare disease with a largely unknown origin. And also corresponding to the diversity of histopathologic characteristics is an equally wide distribution of clinical behavior that makes treatment decisions difficult. The aim of this study is to analysis the clinical experience of our major salivary gland tumor and to suggest a guidline of management. Materials and Methods : We studied clinical manifestations and treatment results of 104 patients who were diagnosed as major salivary gland tumors. Tumor site, patient age and sex of the patients were analysed. Histopathologic diagnosis, treatment modality, lymph nodes metastasis, recurrence rate and 5-year survival rate were studied on malignant tumors. Results: 1) 48 patients were male and 56 patients were female. 2) Benign tumors were 79 cases. They consisted of 57 cases(72%) of parotid tumor, 22 cases(27%) of submandibular tumor. And pleomorphic adenoma was the most common benign tumor. 3) Malignant tumors were 25 cases and were consisted of 19 cases(76%) of parotid tumor, 4 cases(l6%) of submandibular tumor and 2 cases(8%) of sublingual gland tumor with high-grade mucoepidermoid carcinoma as the most common cause. 4) In the malignant tumors, the number of stage I, II tumors was 14 and that of stage III, IV tumors was 11. Neck node metastasis was noted in 8 cases. 5) 8 cases of malignant tumor were died and all of them had high-grade malignancy. And they were dead before 17 months from the time of diagnosis. 6) Mean survival duration in the malignant salivary gland tumor was 56 months. 7) High-grade malignancy had a 5-year survival rate of 57.9%. A 5-year survival rate of TI, T2 patients was 92.9% and that of T3, T4 patients was 36.4%. That of patients who had neck node metastasis was 37.5% and that of those who had tree neck was 82.4%. Conclusion: The results of this study suggest that the survival rate is dependent on the tumor size, lymph node matastasis and histologic grade. And also the early diagnosis and radical surgery result in the increased survival rate and are effective for prevention of the tumor recurrance.

효과적인 항암 약물요법의 발달과 사지의 절단술에 따르는 기능적인 경제적인 비효율성은 뼈의 원발성 암 환자에서 사지 구제술의 발달을 가져 왔다. 소아에서의 사지 구제술은 종양의 광범위 절제 시 성장판이 같이 절제되어 건측과의 사지 길이 차이가 발생하게 될 수 있고 소아 환자들의 왕성한 활동성 때문에 견고하고 내구성 있는 재건술이 필요하다. 소아 환자에서 악성 골종양의 절제 후 성장한 만큼 대치물의 길이도 같이 늘일 수 있는 확장형 종양 대치물(expandable tumor prosthesis)을 이용한 재건술이 시행되어 왔으나 모든 환자에서 만족스러운 결과를 가져오진 못하였다. 최근 들어 확장형 종양 대치물의 발달로 합병증의 발생을 줄이면서 비침습적인 방법으로 사지 길이를 맞추고 종양 대치물의 수명을 길게 하는 시도들이 늘고 있다. 본 논문에서는 확장형 종양 대치물의 적응증, 특성 및 합병증 등에 대해서 짚어 보고자 한다.

Background: Malignant primary cardiac tumors are extremely rare, but have a poor prognosis. This study evaluated the surgical outcomes of patients with this disease. Methods: Forty patients who underwent surgery for malignant primary cardiac tumors between January 1998 and December 2018 were enrolled. Participants were divided into 3 groups based on resection margins (R0, 14 patients; R1, 11 patients; and R2, 11 patients) and their surgical outcomes were compared. Heart transplantation was performed in 4 patients with unresectable tumors. Results: Early mortality was reported in 2 cases (5%) due to postoperative bleeding and cerebral hemorrhage secondary to brain metastasis. The 1- and 2-year survival rates were 67.5% and 42.5%, respectively. The median survival time of the patients was 20.3 months (range, 9.2-37.6 months). The median survival time was 48.7, 20.3, and 4.8 months in patients with R0, R1, and R2 resections, respectively (p=0.023). Tumor recurrence occurred in 21 patients (61.7%), including 4 cases of local recurrence and 17 cases of distant metastasis. In patients who underwent heart transplantation, the median survival time was 29.5 months, with 3 cases of distant metastasis. Conclusion: Although surgery for malignant primary cardiac tumors has a poor prognosis, complete resection of the tumor may improve surgical outcomes.

Breast cancer is the first of the most common ten cancers in Iraq. Its etiology is multifactorial, oxidative stress and lipid peroxidation being suggested to play important roles in carcinogenesis. The purpose of this study was to investigate the oxidant-antioxidant status in breast cancer patients, by measuring SOD isoenzyme activities (total SOD, CuZn-SOD, Mn-SOD and EC-SOD) in plasma and breast tumors, and by estimating thiobarbituric reactive substances (TBRS) in tissue homogenates. General increase in total SOD activity was observed in plasma and tissue samples of breast tumors, greater in the malignant when compared to benign group (p<0.05). Mn-SOD showed a significant decrease in tissue malignant samples (p<0.05), and insignificant decrease in plasma malignant samples compared with control and benign samples. Plasma EC-SOD activity in both patient benign and malignant breast tumors demonstrated 3.5% and 22.8% increase, respectively. However, there was a decrease in tissue EC-SOD activity in malignant breast tumors when compared with benign. A similar tendency was noted for TBRS. We suggest that elevated total SOD might reflect a response to oxidative stress, and then may predict a state of excess reactive oxygen species in the carcinogenesis process. If there is proteolytic removal of the heparin binding domain, EC-SOD will lose its affinity for the extracellular matrix and diffuse out of the tissue. This will result in a decreased EC-SOD activity, thus leading to an increase in the steady-state concentration of $O^{2-}$ in this domain, and increase in EC-SOD activity in the extracellular fluid. This might explain the results recorded here concerning the decrease in tissue EC-SOD activity and increase in plasma of breast cancer patients.
