We report a 65-year-old Japanese woman with Kaposi's sarcoma (KS). The eruption first occurred on the legs while she was admitted for treatment of poorly differentiated lung cancer. Approximately eight months after the evolution, cutaneous tumors rapidly spread to the forearms, trunk, and pharynx. At that time, the patient had received systemic corticosteroid (10-40 mg/day of prednisolone) for about three months to reduce pulmonary inflammation. The laboratory data showed anemia, lymphopenia, hypogammaglobulinemia, and a decreased T cell count, although the serological test for HIV infection was negative. The patient was treated with radiation (X-ray for KS of pharynx and electron beam for KS of lower legs) and local intralesional injection of vinblastine. Although both therapies were very effective and well tolerated, she died of bacterial pneumonia and sepsis. Autopsy revealed KS tumors, unknown before death, in both lungs, the esophagus, and the stomach. The left lung cancer had disseminated and metastasized to the right lung, pleura, mediastinum, and abdominal cavity. It is suspected that chronic respiratory distress and systemic use of corticosteroids might have induced the rapid extension of KS.

From 1980 to 1995, sixteen patients with T4 lung cancer underwent resection of left atrium (LA) or great vessels combined with pulmonary resection. For eight patients with lung cancer invading LA, LA was resected under simple clamp of LA in seven cases, and under extracorporeal circulation in one case. For three patients with lung cancer invading aorta, resection and reconstruction of aorta was performed under femoro-femoral bypass in one case, and under temporary bypass using a heparin-coated tube in two cases. For five patients with lung cancer invading superior vena cava (SVC), SVC was resected under partial clamp or simple clamp of SVC in each case. In remaining three patients, SVC was resected under internal bypass in one case, and under temporary bypass using a heparin-coated tube in two cases. Three were two operative deaths, one (SVC) died of acute heart failure, and the other (LA) died of acute respiratory distress syndrome. Four patients are alive without recurrence and three of them (one LA and two SVC) have been surviving more than five years after operation.

Disruption of the lung architecture by genetic events, environmental insults, or transformation can lead to respiratory diseases such as acute respiratory distress syndrome and lung cancer. Identification of the stem cells of the lung and the processes by which they regulate homeostasis may lead to better targets for treatment of these diseases. There are a number of approaches to study stem cell biology. Development of the lung and the major pulmonary cells of the bronchioles and alveolar regions of the lung is discussed in this review. Likewise, identifying the proteins that are critical for cell-specific expression and differentiation may identify approaches for manipulation of gene expression for use as therapy or treatment of lung diseases. Furthermore, strategies for studying stem cells in the lung are addressed by using the mouse as a model system. Gaining a more detailed understanding of the stem cells of the lung may provide new insight into the processes that govern lung biology and may lead to better treatments for lung diseases. Enthusiasm for the use of exogenous stem cells to replace tissue, organs, or other defective or deficient cells is boundless. Before stem cells can be used indiscriminately for these purposes, understanding tissue genetics and immunology is essential. Progress has been made in these areas for pulmonary disease. Attention to these models will be applicable to other organs and diseases.

Surgical resection is feasible in only 20% of patients with lung cancer: less than 30% of these patients survive > 5 yrs and almost 95% of them require palliative treatment. During the course of disease, 30% of lung cancers cause obstruction of the trachea and main bronchi with subsequent respiratory distress, bleeding and infection. Similar problems arise through secondary pulmonary malignancies. There are several types of central airway obstruction; this influences the modality used for their treatment. The three basic types of stenosis are endoluminal, extraluminal and a combination of both. A mainly endoluminal stenosis can be treated with various resection techniques, such as laser, electrocautery or cryotherapy; for an extraluminal compression the only option is placement of stents, which results in efficient palliation and may prolong survival. Various stent models have been developed for the treatment of inoperable airway stenoses. They consist mainly of two types: metal and silicone devices, or combinations of both (hybrid models). The choice of a specific stent depends on the nature of the airway obstruction, the endoscopist's preference and the overall costs of the procedure. The best treatment results are usually obtained using a combination of stent placement followed by tumour-specific treatment such as irradiation or chemotherapy.

Critically ill cancer patients constitute a large percentage of admissions to tertiary care medical intensive care units (ICUs). We sought to describe outcomes of such patients, and to evaluate how conditions commonly seen in these patients impact mortality. A total of 348 consecutive medical ICU cancer patients were evaluated. Subgroup comparisons included the three most common cancer types (leukemia, lymphoma, lung cancer), as well as three different treatments/conditions (bone marrow transplant [BMT] versus non-BMT, mechanical ventilation [MV] versus non-MV, neutropenic versus non-neutropenic). There were no mortality differences between patients with leukemia, lymphoma, or lung cancer. By logistic regression, mortality predictors were: MV, hepatic failure, and cardiovascular failure for the group as a whole (41% overall mortality); MV and allogeneic (as compared with autologous) BMT for the BMT group (39% overall mortality); hepatic failure, cardiovascular failure, and persistent acute respiratory distress syndrome (ARDS) for the MV group (67% overall mortality); and MV for the neutropenic group (53% overall mortality). Neutropenia showed no independent association with mortality in the group as a whole or any subgroup analyzed. We conclude that respiratory, hepatic, and cardiovascular failure predict mortality, whereas neutropenia does not. Additionally, we have noted an encouraging improvement in survival in many groups of critically ill cancer patients.

The underlying principle of the surgical treatment of non-small-cell lung cancer (NSCLC) is complete removal of the local/regional disease within the thorax. Pulmonary resection should be as conservative as possible without compromising the adequacy of tumor removal. A multitude of factors influence the incidence and severity of complications following pulmonary resection including the pre-operative physical and psychological status of the patient, the pathologic process requiring resection, the physiologic impact of the procedure, and the addition of pre-operative or postoperative adjuvant therapy. The insidious onset of interstitial changes on chest X-ray (CXR) 1 to 2 days after pulmonary resection forewarns of respiratory distress; however, the pathophysiology of adult respiratory distress syndrome (ARDS) with progression to respiratory failure requiring mechanical ventilation and advanced critical care often unfolds. Management of patients with severe respiratory failure remains primarily supportive. "Good critical care" is the mainstay of therapy: this includes gentle mechanical ventilation to avoid ventilator-induced barotrauma and over-extension of remaining functional alveoli, diuresis, infection identification and management, and nutritional support. New therapeutic strategies that may impact on outcomes in the adult population include pressure-limited ventilation (permissive hypercapnia), inverse ratio ventilation, high-frequency jet ventilation, high-frequency oscillatory ventilation, intratracheal pulmonary ventilation, and prone position ventilation. In addition, alternative therapies such as partial liquid ventilation, inhaled nitric oxide, and extracorporeal techniques including extracorporeal membrane oxygenation (ECMO), extracorporeal carbon dioxide removal (ECCO(2)R), intravascular oxygenation (IVOX), and arteriovenous carbon dioxide removal (AVCO(2)R), provide additional modalities. A component of some or all of these strategies is finding a role in clinical practice.

A 63-year-old man complained of rapidly progressive respiratory failure, requiring a control respiration. He subsequently, presented with muscle weakness involving the neck and all the extremities, superimposed by painful paresthesia. He was proven to carry small-cell lung cancer (SCLC). Neurophysiological examinations revealed the waxing phenomenon at 30 Hz repetitive motor nerve stimulation. Positive serum autoantibodies were detected to voltage-gated calcium channel and Hu proteins. He received diagnosis of combined Lambert-Eaton myasthenic syndrome (LEMS) and anti-Hu syndrome. The initial chemotherapy for SCC alleviated his respiratory and neurological symptoms. But he developed multiple cranial palsies and fatal respiratory distress two months later. There is only a few reports about LEMS complicated by respiratory failure as an initial presentation. Various clinical manifestations including respiratory failure at the onset could be best explained by the combination of LEMS and anti-Hu syndrome in this case.

Systemic capillary leak syndrome (SCLS) is a rare disorder with a high mortality rate, characterized by rapidly developing edema, weight gain and hypotension, hemoconcentration and hypoproteinemia. This syndrome is caused by sudden, reversible capillary hyperpermeability with a rapid extravasation of plasma from the intravascular to the interstitial space. Even though SCLS has been suggested to be the pathogenic mechanism for the pulmonary toxicity of gemcitabine (GCB), a new deoxycytidine analogue with structural similarities to cytosine arabinoside, a direct correlation between GCB and SCLS has never been reported. We describe a case of repeated SCLS after GCB administration in a 51-year-old male with locally-advanced non-small-cell lung cancer treated with a combination of cisplatin and GCB. The detection of GCB-induced SCLS supports the hypothesis that SCLS could be the pathogenic way of GCB pulmonary toxicity. This finding can help to better understand and treat the potentially deadly GCB-related acute respiratory distress syndrome that is being recognized.

Therapeutic bronchoscopic techniques such as LPR, EC, brachytherapy, stents, and PDT are effective tools in the palliation and local control of lung cancer. Palliation of malignant tracheobronchial obstruction by LPR, stents, brachytherapy, PDT, or a combination thereof results in relief of dyspnea, hemoptysis, and postobstructive pneumonia. Importantly, it avoids intubation in patients with respiratory distress and facilitates the weaning of patients from MV. In the exciting field of lung cancer screening and treatment of early lung cancer, PDT, brachytherapy, EC, and LPR may represent treatment alternatives to surgical resection, especially in a select group of patients with high surgical risk or favorable endobronchial lesions. Clinicians await the results of future studies, which will (1) better define the impact of each treatment modality on patient care in terms of cost, survival, and improvement in quality of life, and (2) determine the optimal combination therapy relative to bronchoscopic and conventional treatment for effective palliation and cure of lung cancer.

An eight-year-old female German wirehaired pointer was presented with signs of respiratory distress. Clinical examination, laboratory results, thoracic radiography and echocardiography indicated the presence of a diffuse interstitial lung disease with secondary appropriate erythrocytosis, pulmonary hypertension and cor pulmonale. Transthoracic fine needle aspiration biopsy of the lung suggested malignant epithelial neoplasia. A primary lung cancer with an unusually diffuse distribution of miliary/micronodular lesions was found at postmortem examination. Histological diagnosis was bronchiolo-alveolar carcinoma. Bronchiolo-alveolar carcinoma can occasionally occur in a diffuse fashion involving most or all of the lung parenchyma. In man, diffuse bronchiolo-alveolar carcinoma is considered a great imitator of other, more common diffuse interstitial forms of lung disease. This case report indicates that it is also a differential diagnosis to consider in dogs.
