Lung cancer is the most common primary tumor of brain metastasis. Metastasis to the brain is a frequent complication of non-small cell lung cancer (NSCLC) occuring in 12 ~ 18% of patient. The incidence of brain metastasis is rising because of longer survival of cancer patients as a result of the increase in early diagnosis of primary tumors and aggressive management, and improvements in imaging quality and accessibility such as widespread use of MRI. The most common symptoms are gradual onset of headache, focal weakness, and mental changes. Surgery, chemotherapy, radiotherapy and steroid therapy are treatment of NSCLC with brain metastasis. We report a patient with NSCLC metastasis to the brain. This patient underwent chemotherapy, radiotherapy and steroidtherapy. However, the patient requested oriental medical treatment for the patient's continuous headache and disease. We administered Banhabaekchulchoenma-tang gagambang with Allergen-removed Rhus Verniciflua Stokes(aRVS). The patient showed remarkable improvement in terms of frequency and severity of headache. Further study will be needed in order to determine the long-term effectiveness of oriental medical treatment on cancer patient with headache.

Bronchial carcinoids were classified as one of the bronchial adenoma group and constituted about 90% of bronchial adenoma. Typical carcinoids are common benign neoplasms of the airway because of their uniform histologic feature, predictable clinical course and good survival after surgical resection. And atypical carcinoid is regarded as a malignant tumor because of its pleomorphic, hyperchromatic nucleus, frequent mitosis and distant metastasis (about 70%). However, typical carcinoids rarely metastasize to regional lymph nodes and such cases would be regarded as a low grade malignancy because their clinical prognosis could be bad. We present a case of typical bronchial carcinoid which metastasize to hilar lymph node who has been followed up 10 months after resection.

Wanpae-tang is suggested to have antitumor activity on lung cancer. This study was performed to investigate antitumor, immune response, and apoptotic effects by Wanpae-tang in the cancer cell lines and C57BL/6 mice. Experimental studies were progressed through the anticancer activities such as, survival time, cell cytotoxicity, natural killer cell activity, productivity of interleukins and apoptotio effects. The results were summarized as follows: 1. Median survival time of Wanpae-tang treated group was prolonged to 4.1%, as compared with control group, but was not significant. 2. On the MTT assay, half-maximal inhibitory concentration(IC50) of Wanpae-tang was 15.00 ㎎/㎖ in HeLa cell, and 4.158 ㎎/㎖ in HRT-18 cell. 3. Natural killer cell activity in Wanpae-tang treated group was decreased in case of 100:1 and 10:1 effect cell/target cell ratio. 4. Production of interleukin-2, 4, 12 in Wanpae-tang treated group were significantly increased. 5. On the studies of Wanpae-tang induced apoptosis, a DNA fragmentation patterns were not appeared.

Background and Objectives: Recently the tenn 'papillary microcarcinoma' has been proposed to designate carcinoma of 10 mm or less in diameter. In some cases, cervical lymph node metastasis preceding the occurrence of the primary tumor may be the first and sole manifestation of the disease. The objective of this study is to assess the clinical features of cervical metastasis in papillary microcarcinoma of thyroid glands. Materials and Methods: 9 cases with papillary microcarcinoma with neck metastasis were analyzed retrospectively. 5 cases are men and 4 are women. All patients complained of painless, movable neck mass. The symptom had been present from 1 month to 36 months. We reviewed clinical history, imaging studies, the results of fine needle aspiration, the surgical method, the pathologic results. Results: In 9 cases, no abnormalities of the thyroid gland were shown by imaging studies and thyroid scan. 3 cases were diagnosed by fine needle aspiration cytology. the others were not. Total thyroidectomy and neck dissection were performed in 9 cases and then pathology reports showed 2 case of multiple, 2 case of contralateral single and 5 cases of unilateral single thyroid microcarcinoma. They have no recurrence during follow-up period. Conclusions: Cervical metastasis from papillary microcarcinoma is variable clinical manifestation. The diagnosis of cervical metastasis from papillary microcarcinoma should be considered in patient with neck mass. We recommend total thyroidectomy with neck dissection and postoperative radioactive iodine ablation therapy in neck metastasis from papillary thyroid microcarcinoma.

Early detection of glottic cancer, facilitated by rigid telescopes or flexible fiberoptic laryngoscope in addition to sparse true vocal cord lymphatics, makes this a highly curable tumor in its early stage. Early glottic cancer has a high cure rate with only radiotherapy or conservative surgery. However complications such as mucositis with radiotherapy and voice complications with conservative surgery has raised recent interest in endolaryngeal laser cordectomy. Laser cordectomy can preserve phonatory function and avoid the complications such as mucositis of radiotherapy. To determine the effectiveness of laser cordectomy, the authors made a two year retrospective study of 23 early glottic cancer cases. Fourteen cases(60.9%) who underwent 1 to 3 endoscopic laser cordectomy with KTP-532 laser were cured with this procedure alone. Seven cases needed an additional radiotherapy and three cases needed therapy with salvage operation. We conclude that the endoscopic laser surgery is a good strategy for the properly selected glottic cancer.

Approximately 10-15% of pheochromocytomas are malignant. There are insufficient histologic criteria for the diagnosis of malignant pheochromocytoma. Thus, the term malignant pheochromocytoma is restricted to tumors with local invasion or distant metastases. We experienced a case of malignant pheochromocytoma recurred with spinal metastasis 4 years after the surgery for huge benign pheochromocytoma. A 68-year-old female was admitted for trunk and back pain. The patient had a history of surgery 4 years ago for a $10.0{\times}9.5{\times}7.5cm$ sized benign pheochromocytoma at the left adrenal gland. A thoracolumbar magnetic resonance imaging showed a tumor in the 7th thoracic vertebral body and a 24-hour urinary norepinephrine increased, suggesting metastatic recurrence of malignant pheochromocytoma. After metastasectomy in the 7th thoracic vertebral body, urine catecholamine was normalized and pain also disappeared. However, a metastatic lesion was found in the paraaortic area on a follow-up abdominal computed tomography scan and an additional metastasectomy was performed. The pathology confirmed the diagnosis of metastatic pheochromocytoma in the paraaortic lymph nodes. She is supposed to be treated with adjuvant iodine 131-meta-iodobenzylguanidine therapy. In our experience, a close follow-up should be considered in patients who had a huge benign pheochromocytoma due to the possibility of malignant metastases.

Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%), Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal ceil carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

Since 1950s, fine needle aspiration(FNA) cytology has become increasingly popular and numerous reports have demonstrate its accuracy, safety and cost-effectiveness. To evaluate the role of diagnostic FNA cytology in the thyroid nodule, authors compared preoperative cytologic findings with postoperative histologic diagnosis in two hundred two thyroid nodules underwent surgical resection at Department of Surgery, Pusan Paik Hospital. from July 1990 to December 1993. FNA and thyroidectomy was performed primarily by one Head and Neck surgeon and specimen was interpreted by several pathologists. One hundred seventy two FNAs(85%) were interpreted as positive for benign lesion or carcinoma and thirty(15%, cystic in 25, non-cystic lesion in 5 cases) were unsatisfactory specimens for interpretation. The preoperative cytologic diagnosis of 172 cases revealed 'benign' in 112. 'suspicious cancer' in 10 and 'cancer' in 50 cases. Postoperative pathologic diagnosis showed 'nodular goiter' in 64. 'benign tumor' in 43, 'thyroiditis' in 4 and 'cancer' in 61 cases. The value of preoperative FNA diagnosis for thyroid cancer yielded a sensitivity of 85.2%, a specificity of 92.7%, false negative rate 5.2%, false positive rate 4.5% and positive predictive value and overall accuracy were 86.6% and 90.1% respectively. Preoperative rate of malignancy could be increased up to 35.5% by using FNA.

A 34-year-old man was admitted to our hospital due to fever and cough. He received the combination anti-cancer chemotherapy for testicular tumor, including bleomycin. The chest X-ray showed consolidation and ground glass opacity on the right upper lobe and subpleural areas of other lobes. This condition was initially misdiagnosed as a pneuomonia, but consolidation did not disappear after antibiotics treatment. We performed transbronchial lung biopsy and bleomycin induced pulmonary toxicity was confirmed. The bleomycin induced lung injury is the most common chemotherapeutically induced pulmonary disease. Bleomycin induced Bronchiolitis Obliterans Organizing Pneumonia(BOOP) is less common than interstitial pneumonitis and responds well to corticosteroid treatment.

The present investigation aims at elucidating a possible mechanism of heat inactivation of SCK ceils by comparing the kinetics of cell lethality and protein degradation in the presence of heat protector or heat sensitizer. The effect of heat sensitizer and protector was exhibited in both cell survival and protein degradation kinetics, the magnitude of the effect being much profound for the protector compared to the sensitizer. A conclusion to he drawn from the present experiment is that there is no direct correlation between cell lethality and protein degradation. Rather, protein degradation, which might occur in the membrane, causes cell inactivation indirectly, possibly by altering the cellular environment. Accordingly, further studies are needed to get insight into the mechanism of cell inactivation by hyperthermia.
