1/445. Pulmonary vein obstruction by bronchogenic carcinoma.

    Two patients with obstruction of the pulmonary veins by bronchogenic carcinoma, an unusual cause, are presented. These and other cases reported have had features suggestive of mitral stenosis. The differential diagnosis is discussed. ( info)

2/445. Bronchogenic carcinoma presenting as a bronchopericardial fistula.

    A case is reported in which an undiagnosed bronchogenic carcinoma presented clinically with sudden onset shortness of breath and cardiac failure due to the development of an acute bronchopericardial fistula. ( info)

3/445. Bilevel non-invasive ventilation in malignant large airways obstruction during chemotherapy and radiotherapy.

    A case is described of acute respiratory failure secondary to variable intrathoracic large airway obstruction due to a lung neoplasm. Successful ventilation was achieved with facemask bilevel non-invasive ventilatory assistance allowing radiotherapy and chemotherapy to be undertaken. ( info)

4/445. pituitary apoplexy following metastasis of bronchogenic adenocarcinoma to a prolactinoma.

    A 42-year-old house wife presented with worsening headaches over 6 months in the absence of visual symptoms or symptoms suggestive of focal neurology. She was a life-long smoker. Systems review was unremarkable apart from secondary amenorrhoea and galactorrhoea of 6 months duration. Her serum prolactin was found to be 620 mU/l (60-400), FT4 12.6 nmol/l (9.8-23.1), TSH 1.38 mU/l (0.35-5.5), oestradiol < 73 pmol/l, LH and FSH of 4.4 and 12.6 mIU/l, respectively. She was on bromocriptine. A presumptive diagnosis of pneumonia, based on pyrexia and CXR findings, was made and she was started on IV antibiotics. Two days later she developed meningism and deterioration of conscious level. (Lumbar puncture results: no organisms, 312 neutrophils and 164 lymphocytes). CT scan revealed a 2.5-cm pituitary adenoma, with suprasellar extension. A repeat hormonal profile revealed FSH 1.4, LH < 0.3 mU/l, oestradiol < 73 pmol/l, prolactin 488 mU/l (60-400), and low random cortisol at 29 nmol/l. T1-weighted MRI revealed a large pituitary mass with evidence of haemorrhage. The patient subsequently underwent a transsphenoidal exploration with resection of the pituitary lesion. Whilst awaiting the histopathology results, CT of chest revealed a 1. 5-cm diameter rounded well defined density in the right lower lobe associated with hilar, pre- and right para-tracheal lymphadenopathy. The histopathology of the pituitary lesion, obtained piecemeal, revealed fragments of fibrous tissue infiltrated by sheets of acidophilic prolactin-positive cells, in keeping with a prolactinoma. In addition, other fragments with blood clot included highly atypical epithelial cells with mitotic figures. These were negative for prolactin but showed HMFG-and CEA-positivity, excluding them from a pituitary lineage. Transbronchial biopsy revealed moderately differentiated adenocarcinoma, with evidence of lymphatic spread. The overall conclusion was of bronchogenic adenocarcinoma, metastasizing to a prolactinoma and complicated by apoplexy. ( info)

5/445. Left sleeve pneumonectomy performed through a clamshell incision with extracorporeal membrane oxygenation for bronchogenic carcinoma: report of two cases.

    We report herein the cases of two patients with bronchial gland carcinomas in the left main bronchus who were successfully treated by left sleeve pneumonectomy performed through a clamshell incision. Adequate oxygenation during pathological examination of tumor invasion at the bronchial stumps and the tracheobronchial anastomoses was achieved by extracorporeal membrane oxygenation (ECMO) in both patients. Tracheobronchial anastomosis was relatively easy to perform in the excellent operative field achieved by this method. The postoperative courses of both patients were uneventful, although they developed temporary pulmonary edema that was effectively controlled by mechanical ventilation and appropriate diuresis. The procedure presented in this paper is considered to be a safe and effective method of performing left sleeve pneumonectomy. ( info)

6/445. Long-term survival after surgical resections of bronchogenic carcinoma and adrenal metastasis.

    There is some evidence that complete resection of both primary and metastatic sites of non-small cell lung carcinoma has more influence on survival than the locoregional stage of the lung cancer. We describe prolonged survival (>5 years) after complete surgical resection of a bronchogenic carcinoma (T3N0M1) and solitary adrenal metastasis. ( info)

7/445. thallium and FDG uptake by atelectasis with bronchogenic carcinoma.

    We report a case of bronchogenic carcinoma with atelectasis studied by T1-SPECT and FDG-PET. In the carcinoma, abnormally high uptake of T1 and FDG were detected, but in the region of atelectasis, an abnormally high uptake of T1 with a relatively low uptake of FDG were observed. On quantitative analyses, the T1 retention indexes of the tumor and atelectasis were 29.7 and 42.0. The mean SUVs of FDG of the tumor and the atelectasis were 8.92 and 1.28. T1-SPECT could not distinguish the atelectasis from the carcinoma. FDG-PET was superior to T1-SPECT in this case in detecting malignancy and distinguishing it from atelectasis. ( info)

8/445. Tracheal bronchus associated with lung cancer: a case report.

    Tracheal bronchus is a rarely found congenital bronchial anomaly. It usually originates from the right lateral wall of the trachea at the level < 2 cm above the tracheal bifurcation. The patients usually are asymptomatic, but some may experience recurrent pneumonia, chronic bronchitis, or bronchiectasis. It is very rare for a malignant tumor to grow from this aberrant bronchus. There are only four cases of lung cancer developing from the tracheal bronchus reported in the world literature, and we present a fifth case. ( info)

9/445. Improved ventilatory function after combined operation for pulmonary emphysema and lung cancer.

    BACKGROUND: smoking is the leading cause of both lung cancer and emphysema. Therefore, some patients with stage I and II disease will present with contra-indications to resection including a predicted postoperative FEV1 of less than 0.81 or a VO2max of less than 10 ml/kg/min. Recently, lung volume reduction surgery (LVRS) has re-emerged in the management of emphysema with excellent results. methods AND patients: 2 patients are reported with lung cancer in the left lower lobe and emphysematous destruction in both upper lobes. They, respectively, had a predicted postoperative FEV1 of 0.9211 and 0.6851. No metastases were present. Pre-operatively, a COPD index of 0.9 and 0.7 was calculated. A left lower lobectomy together with volume reduction of the left upper lobe was performed through a standard posterolateral thoracotomy. RESULTS: Pathological examination showed, respectively, stage IIb and stage Ib disease. The postoperative course was uneventful and 3 months later a FEV1 of 1.441 for patient 1 and 1.041 for patient 2 were recorded. CONCLUSION: These findings suggest that pulmonary function criteria for pulmonary resection have to be revised when patients can undergo simultaneous lung cancer resection and LVRS. The pre-operatively calculated COPD index can be used to predict which patients may not have a decrease in ventilatory function. ( info)

10/445. Successful treatment of a patient with ARDS after pneumonectomy using high-frequency oscillatory ventilation.

    High frequency oscillatory ventilation (HFOV) was used in a patient who developed the acute respiratory distress syndrome 5 days following a right pneumonectomy for bronchogenic carcinoma. When conventional pressure-controlled ventilation failed to maintain adequate oxygenation, HFOV dramatically improved oxygenation within the first few hours of therapy. Pulmonary function and gas exchange recovered during a 10-day period of HFOV. No negative side effects were observed. Early use of HFOV may be a beneficial ventilation strategy for adults with acute pulmonary failure, even in the postoperative period after lung resection. ( info)
