The Lambert-Eaton myasthenic syndrome (LEMS) is typically recognized as a paraneoplastic syndrome associated with a small cell lung carcinoma (SCLC), whereas LEMS with other neuroendocrine lung tumors, including carcinoids or large cell lung carcinoma, are highly unusual. Here, we report a rare case of LEMS with atypical bronchopulmonary carcinoid tumor: A 65-yr-old man presented with progressive leg weakness and a diagnosis of LEMS was made by serial repetitive nerve stimulation test. Chest CT revealed a lung nodule with enlargement of paratracheal lymph nodes, and surgically resected lesion showed pathological features of atypical carcinoid tumor. We concluded that LEMS could be associated with rare pulmonary neuroendocrine tumor other than SCLC, which necessitates pathologic confirmation followed by aggressive treatment for optimal management in these rare cases.

Phyllodes tumor is a rare breast tumor. A 45-year-old woman who underwent left mastectomy 12 years ago was found to have infiltrates in both lungs in a health examination. Combining histological examinations of the lung and breast samples, the diagnosis of borderline phyllodes tumor metastases to the lung was made. It is the longest interval to our knowledge that the metastases occurred 12 years after primary phyllodes tumor.

OBJECTIVETo evaluate and compare the value of stair climbing tests and conventional pulmonary function tests in the prediction of postoperative cardiopulmonary complications in non-small cell lung cancer patients underwent surgery.

METHODSFrom April 1, 2010 to Jan. 30, 2012, a total of 162 patients with thoracic carcinoma underwent stair climbing test (SCT) and conventional pulmonary function tests (PFT) preoperatively. The correlation of postoperative cardiopulmonary complications with the SCT and PFT parameters were analyzed retrospectively using chi-square test, independent sample t test and binary logistic regression analysis.

RESULTSOf the 162 patients, 19 without operation were excluded, due to an advanced stage (9 cases), poor cardiopulmonary function (5 cases), rejecting operation (4 cases) and exploration alone (1 case). 143 cases were eligible and evaluated eventually. Forty-one of the 143 patients (28.7%) had postoperative cardiopulmonary complications, but no death occurred. The patients were stratified into groups based on the time of stair climbing 5 stories (18.36 m, t, <92 s, ≥ 92 s). Exercise oxygen desaturation (EOD) during the stair climbing test (<5%, ≥ 5%) and the difference between the pulse at resting state and the pulse at end of stair climbing test (ΔP, <55 beats/min, ≥ 55 beats/min), respectively. The rate of postoperative cardiopulmonary complications was significantly higher in the group with t ≥ 92 s, EOD ≥ 5% and ΔP < 55 beats/min (38.5%, 42.0% and 35.1%, respectively) than that in the group with t<92 s, EOD<5% and ΔP ≥ 55 beats/min (16.9%, 21.5% and 18.2%, respectively). Binary logistic regression analysis showed that postoperative cardiopulmonary complications were independently correlated with EOD and lung function which did not meet the requirement of the lung resection operation mode.

CONCLUSIONSA symptom-limited stair climbing test is a safe, simple and low-cost method to evaluate the cardiopulmonary function preoperatively. It can predict the occurrence of postoperative cardiopulmonary complications in non-small cell lung cancer patients. Conventional pulmonary function tests and stair-climbing test can be recommended to be routinely performed in all patients with non-small cell lung cancer before thoracic surgery.

Carcinosarcoma is defined as a malignant tumor with an admixture of carcinoma and sarcoma. Pulmonary carcinosarcoma accounts for about 0.27 percent of all lung neoplasms. It occurs frequently in males, particularly in smokers between 50 and 80 years of age. Preoperative diagnostic tests, such as sputum cytology, percutaneous fine needle biopsy and bronchoscopy, have a low yield in detection of pulmonary carcinosarcoma. The diagnosis is verified by postoperative pathologic findings and by immunohistochemical investigations in many cases. Surgical resection is the treatment of choice. As the metastasis to regional lymph nodes and distant organ is common at diagnosed time, the prognosis is quite poor. We report a case of pulmonary carcinosarcoma presented with persistent mild fever and blood-tinged sputum in a 66-year-old male.

A 28-year-old female with a pregnant state of 29th gestational week was admitted because of nausea and vomiting. MRI showed a huge hepatocellular carcinoma. At the 36th gestational week, a normal delivery was done. Surgery of hepatocellular carcinoma was done at 20 days after delivery. After 22 months from the operation, pulmonary metastasis was found and resection of lung mass was done. About 3 years after resection, a low attenuating nodule was detected in the left atrial chamber of heart. We report a case of hepatocellular carcinoma with metastatic lesions to lung and heart in a pregnant woman.

Although gynecomastia is a well-defined paraneoplastic syndrome in patients with non-small cell lung cancer, the association with pleomorphic carcinoma has not been reported. A 50-yr-old man presented with bilateral gynecomastia and elevated serum beta-human chorionic gonadotropin (beta hCG) level. Chest tomography showed a mass in the right middle lobe. Right middle lobectomy and mediastinal lymph node dissection were performed. beta hCG levels decreased rapidly after surgery. Histological examination revealed pleomorphic carcinoma with positive immunostaining for beta hCG. Serum beta hCG levels began to increase gradually on postoperatively 4th month. Computed tomography detected recurrence and chemotherapy was started. After second cycle of chemotherapy, beta hCG levels decreased dramatically again and tomography showed regression in mass. Patient died 6 months later due to brain metastasis. beta hCG expression may be associated with aggressive clinical course and increased risk of recurrence, also beta hCG levels may be used to evaluate therapy response in patients with pleomorphic carcinoma.

PURPOSE: The purpose of this study was to identify the effects of a Progressive Walking program (PW) on physical activity, exercise tolerance, recovery, and post-operative complications for patients with a lung resection. METHODS: A nonequivalent control group non-synchronized design was utilized and 37 participants with a lung resection (22 for control group, 15 for experimental group) were recruited at A university hospital from December 2012 to August 2013. The PW consisted of preoperative education, goal setting, and feedback, provided to the experimental group, and usual care to the control group. Data were analyzed using the SPSS WIN 18.0. RESULTS: A higher proportion of patients in the experimental group showed adequate levels of physical activity (p=.001), shorter period of chest tube retention (< or = 7 days; p=.011), and shorter stay in the hospital (< or = 10 days; p=.036) than patients in the control group. Patients in the experimental group reported longer 6-minute walking distance (p=.032) and lower levels of dyspnea (p=.049) than patients in the control group. The PW did not influence the occurrence of pulmonary complications. CONCLUSION: The findings of this study suggest that the PW could be a useful strategy for improving patients' post-operative health and reducing cost after lung resection.

A case of inflammatory pseudotumor of the lung occurring in a six-year-old boy is reported with clinicopathologic findings, including its ultrastructure. The patient had had frequent upper respiratory tract infections, and one and half year before the discovery of the lung mass, he suffered from pneumonia of the right lung, which was serologically proven to be a mycoplasma pneumoniae infection. Exploratory thoracotomy revealed a large mediastinal mass that was removed together with the right middle and lower lobes of the lung. The mass arose from the lung with an endobronchial element. Microscopically, the mass was composed of a variety of inflammatory and mesenchymal cells, including plasma cells, histiocytes, lymphocytes, and fibroblast-like spindle cells. Ultrastructurally, the spindle-shaped mesenchymal cells were either fibroblasts or myofibroblasts. At the time of diagnosis of the inflammatory pseudotumor of the lung, the serum titer of antimycoplasma antibody rose again, and the lung parenchyma adjacent to the mass showed interstitial pneumonia with features of bronchiolitis obliterans. The present case suggests that the inflammatory pseudotumor of the lung could be a postinflammatory lesion associated with mycoplasma pneumoniae infection.
