    ABSTRACT: A 37-year-old woman was referred to our institution for further management of a mass lesion located in the thoracic cavity. The mass had grown by more than 10 cm over the course of a year and was initially considered to be a scar from previous pulmonary tuberculosis at another hospital. The patient had complained of left-sided flank pain for a year and experienced dyspnea for one month. Chest radiography and chest computed tomography revealed an irregular-shaped mass in the left mid to lower pleural cavity. The mass was widely excised through left thoracotomy. Pathologic examination of the biopsy specimen revealed a malignant spindle cell tumor, which consisted of components of osteosarcoma, pleomorphic sarcoma, and leiomyosarcoma. The patient underwent adjuvant chemotherapy and has been doing well without any evidence of recurrence for 14 months.

    ABSTRACT: The standard regimen in elderly patients with non-small-cell lung cancer (NSCLC) is still uncertain. Gemcitabine is one of the most widely used drugs for the treatment of NSCLC, and several phase II trials specifically designed for elderly patients with advanced NSCLC have confirmed the role of gemcitabine in this setting. In addition, oral uracil-tegafur (UFT) was associated with a survival advantage in the adjuvant setting. Therefore, we performed a phase II study using the combination of gemcitabine and UFT as first-line therapy in elderly patients with advanced NSCLC. Chemotherapy-naïve, elderly (≥ 70 years) patients who had histologically or cytologically confirmed with stage IIIB or IV NSCLC with a performance status of 1-2 were enrolled. Patients received gemcitabine (1250 mg/m(2) on days 1 and 8, respectively) and UFT (400mg/day on days 1-14) every 3 weeks for up to four cycles. Patients who had not progressed after four cycles continued UFT monotherapy until progression. Primary endpoint was overall response rate and secondary endpoints were overall survival, time to progression and safety profiles. Between March 2008 and November 2010, 48 patients were enrolled. The median age was 74.5 years (range: 70-84 years), and there were 29 males. The performance status was 1 in 41 and 2 in 7 patients. Thirty-one (64.6%) patients were stage IV and seventeen (35.4%) patients were stage IIIB. Thirty patients (62.5%) completed four cycles of chemotherapy. Response was evaluated in 44 patients. Partial response was achieved in twelve (25.0%) patients and stable disease in 23 (47.9%) patients. Disease control rate was 72.9%. The median survival time was 6.1 months (95% confidence interval [CI]; 5.1-7.0 months), the 1-year survival rate was 29.1% and the median time to progression was 4.6 months (95% CI; 3.7-5.5 months). Toxicities were mild and mostly hematological adverse events. Grade 3/4 neutropenia occurred in 8.3% of patients and one patients experienced febrile neutropenia. Grade 3/4 anemia and thrombocytopenia occurred in 2.1% and 2.1% of patients, respectively. Non-hematological toxicities were tolerable. The combination of gemcitabine and UFT was effective in disease control and well tolerated first-line regimen in elderly patients with advanced NSCLC.

    ABSTRACT: Hemangiomas that arise in cervical esophagus are extremely rare, representing 3.3% of all benign esophageal tumors. Although endoscopic mucosal resection (EMR) and potassium titanyl phosphate/yttrium aluminum garnet (KTP/YAG) laser therapy have been used with success for small tumors, the safety and efficacy in the case of large tumors remains uncertain. We report the successful resection of cervical esophageal hemangioma through a cervical esophagotomy in a patient with thyroid cancer who needed a cervical collar incision.

    ABSTRACT: Acupuncture-related hemopericardium is a rare but potentially fatal complication. We describe a hemopericardium that occurred shortly after acupuncture in a 55-year-old woman. A chest CT scan and echocardiography revealed a hemopericardium, and pericardiocentesis was then immediately and successfully performed. Subsequently, her clinical course improved. This case increases the attention of emergency physicians for acupuncture-related complications, especially hemopericardium, and the necessity of rapid diagnosis and management.
