ABSTRACT
Primary tumors of the lung are uncommon in pediatric patients, particularly bronchioloalveolar carcinoma (BAC). An 11-year-old female suffering from back pain for 1 month was referred to Seoul St. Mary's Hospital for treatment of a pathologic fracture of the lumbar spine. Comprehensive evaluation disclosed numerous pulmonary metastases of rhabdomyosarcoma (stage IV). During chemotherapy, most of the lung lesions regressed, with the exception of two nodules. Wedge resections, intended for diagnosis and cure, yielded a histologic diagnosis of BAC.

The granular cell tumor (GCT) occurs extremely rarely in the mediastinum. Few mediastinal GCT cases have been reported in Japan or other countries. Here, we report a case of a 24-year-old man with superior mediastinal GCT. The mass was located just above the aortic arch. It was firm, oval in shape, and well encapsulated. The tumor was removed completely with video-assisted thoracoscopic surgery, but we had to resect the vagus nerve, which was already included in the tumor, along with the tumor. After the operation, the patient recovered without any specific complications except for a mild degree of hoarseness.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

BACKGROUND: Pulmonary hamartomas are the most common form of pulmonary benign tumors, and they occur in approximately 2~5% of all pulmonary neoplasm. However, only a few reports have been published on the clinical characteristics of pulmonary hamartoma in Korea. MATERIAL AND METHOD: The charts, X-rays and pathological specimens of 37 pulmonary hamartoma patients who were diagnosed by a pathological examination from January of 2000 to May of 2005 at the Catholic Medical Center were retrospectively reviewed. RESULT: The peak incidence of the tumor occurred in the seventh decade of life (32.4%). There were 23 men (62.6%) and 14 women (37.8%), with mean age of 55.6 years. Twenty-six patients (70.3%) were asymptomatic and 11 patients (29.7%) had symptoms. A total of 29 tumors (78.4%) were parenchymal, and 8 (21.6%) were endobronchial. Twenty cases (54.1%) were in the right lung and 17 cases (45.9%) were in the left lung. The right lower lobe was most commonly involved. Thirty-two (86.5%) hamartomas were diagnosed by surgical resection, 4 cases (10.8%) were diagnosed by bronchoscopic biopsy and 1 case (2.7%) was diagnosed by a fine needle aspiration biopsy. Thirty-four hamartomas (91.9%) were managed by surgical resection without complication. No recurrence or malignant changes were seen during the follow up period. CONCLUSION: Pulmonary hamartomas are most common in males during their fifth to seventh decade and they more commonly involve the right lung. No recurrence or malignant changes were seen during the follow up period.

Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve replacement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.

BACKGROUND: Recent progress in the surgical therapy for lung cancer is one of the best examples of the successful evolution of clinical medicine. We reviewed our experience to evaluate the surgical outcomes in patients with non-small cell lung cancer. MATERIAL AND METHOD: We reviewed clinical records of 432 consecutive patients with proven non-small cell lung cancer who underwent complete removal of the primary tumor together with hilar and mediastinal lymph nodes from 1995 to 2005. The clinical characteristics, surgical methods, and recurrence patterns were analyzed. RESULT: Lobectomy was the most common procedure (66.7%) performed and sleeve lobectomy was the least (5.6%). In 179 patients (42.6%) the recurrence was noted and the regional recurrence (67 cases, 16.0%) was less than systemic recurrence (112 cases, 26.7%). The main sites of regional recurrence were hilum (25 cases, 37.3%) and ipsilateral mediastinum (17 cases, 25.4%). The hospital mortality rate was 2.8% (12/432 cases) and resection-morbidity rate was 12.5% (54/432 cases). CONCLUSION: The low recurrence rate, especially regional recurrence rate indicated that our surgical procedures with preoperative measures were considered useful and effective.

Pericardial cysts are uncommon benign congenital mediastinal lesions and they are most often found in either cardiophrenic angle. We present here one case of atypically located pericardial cyst that was located in the subpulmonary region. The clinicians should take into consideration this entity in the differential diagnosis of cystic lesion of the mediastinum. The diagnostic difficulties that are encountered and the utility of video-assisted thoracoscopy are described.

PURPOSE: Recent progress in the surgical therapy for lung cancer is one of the best examples of the successful evolution of clinical medicine. We reviewed our experience to evaluate the surgical outcomes in patients with non-small cell lung cancer. MATERIALS AND METHODS: We reviewed clinical records of 236 consecutive patients with proven primary non-small cell lung cancer who underwent complete removal of the primary tumor together with hilar and mediastinal lymph nodes from 1995 to 2005. The clinical characteristics, surgical methods, and recurrence patterns were analysed. RESULTS: The patients of stage III and IV were 71 cases (35.9%) and 2 cases (1.0%) respectively, and neoadjuvant therapy was done in 62 patients. Lobectomy was the most common procedure (69.7%) performed and pneumonectomy was the least (5.6%). In 81 patients (40.9%) the recurrence was noted and the regional recurrence (27 cases, 13.6%) was less than systemic recurrence (54 cases, 27.3%). The main sites of regional recurrence were hilum (11 cases, 40.7%) and ipsilateral mediastinum (9 cases, 33.3%). CONCLUSION: These data indicated that our surgical methods were useful and effective

BACKGROUND: In recent years, a combination of two demographic phenomena, an increased number of older people in the population and an increase in the incidence of lung cancer with age, has made it mandatory to develop therapeutic modalities with less toxicity for the treatment of inoperable elderly patients with lung cancer. Therefore, we investigated the correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. MATERIAL AND METHOD: Immunohistochemical staining of COX-2 was performed. After exposure of Nimesulide, XTT analysis, FACS analysis and Hoechst staining were carried out. RESULT: COX-2 protein was expressed in non- treated A549 cells strongly, but not in H1299. Cytotoxicity of Nimesulide against A549 cell and H1299 cell were similar and IC50 of Nimesulide in both cell lines were 70.9 microM in A549 cell line and 56.5 microM in H1299 cell line respectively. FACS analysis showed G0/G1 arrest in both cell lines and the S phase cell fraction was decreased. Morphologic assessment of apoptosis by Hoechst 33258 staining, many apoptotic cells were detected in both cell lines. CONCLUSION: Selective COX-2 inhibitor, Nimesulide, can inhibit the proliferation of non-small cell lung cancer cell lines in vitro. Inhibitory effect of Nimesulide are induction of apoptosis and G0/G1 arrest. There is no correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. Therefore, highly selective COX-2 inhibitors such as Nimesulide can be expected to lead to even greater efficacy of their use as adjuncts to various anticancer angents and radiation therapy for the treatment of high-risk patients.
