Objective: To describe demographic characteristics, surgical results, postoperative complications, and overall survival rates in surgically treated patients with lung metastases. Methods: This was a retrospective analysis of 119 patients who underwent a total of 154 lung metastasis resections between 1997 and 2011. Results: Among the 119 patients, 68 (57.1%) were male and 108 (90.8%) were White. The median age was 52 years (range, 15-75 years). In this sample, 63 patients (52.9%) presented with comorbidities, the most common being systemic arterial hypertension (69.8%) and diabetes (19.0%). Primary colorectal tumors (47.9%) and musculoskeletal tumors (21.8%) were the main sites of origin of the metastases. Approximately 24% of the patients underwent more than one resection of the lesions, and 71% had adjuvant treatment prior to metastasectomy. The rate of lung metastasis recurrence was 19.3%, and the median disease-free interval was 23 months. The main surgical access used was thoracotomy (78%), and the most common approach was wedge resection with segmentectomy (51%). The rate of postoperative complications was 22%, and perioperative mortality was 1.9%. The overall survival rates at 12, 36, 60, and 120 months were 96%, 77%, 56%, and 39%, respectively. A Cox analysis confirmed that complications within the first 30 postoperative days were associated with poor prognosis (hazard ratio = 1.81; 95% CI: 1.09-3.06; p = 0.02). Conclusions: Surgical treatment of lung metastases is safe and effective, with good overall survival, especially in patients with fewer metastases.

Mucoepidermoid carcinoma of the trachea mimicking asthma

Carcinoma mucoepidermoide da traqueia mimetizando asma brônquica

Ricardo Kalaf Mussi, Ivan Felizardo Contrera Toro, Mônica Corso Pereira

J Bras Pneumol.2009;35(3):280-284

Abstract PDF PT PDF EN Portuguese Text

In cases of recent asthma in which clinical control with the usual treatment (corticosteroids and bronchodilator) is unsatisfactory, it is important to consider other diagnoses, such as congestive heart failure, gastroesophageal reflux or other forms of airway obstruction. We report the case of a female patient with mucoepidermoid carcinoma of the trachea mimicking asthma. The patient presented cough and wheezing, as well as abnormal spirometry results with an obstructive pattern that was responsive to bronchodilators. One year later, the patient presented clinical and spirometric worsening. The chest X-ray revealed no abnormalities. A CT scan showed a vegetative lesion obstructing the tracheal lumen and located 1 cm from the carina. Fiberoptic bronchoscopy showed a finding similar to a bronchial carcinoid tumor. The anatomopathological diagnosis made after surgical resection was low-grade mucoepidermoid carcinoma, without lymph node involvement. Although the flow-volume curve was not suggestive of upper airway obstruction, the spirometry performed after the surgery showed a significant reduction in the degree of obstruction and greater reversibility after bronchodilator use. There was no evidence of recurrence of the disease or of the symptoms after a two-year follow-up period.

Negative-pressure pulmonary edema and hemorrhage associated with upper airway obstruction

Edema e hemorragia pulmonar por pressão negativa associados à obstrução das vias aéreas superiores

Ricardo Kalaf Mussi, Ivan Felizardo Contrera Toro

J Bras Pneumol.2008;34(6):420-424

Abstract PDF PT PDF EN Portuguese Text

Negative-pressure pulmonary edema accompanied by hemorrhage as a manifestation of upper airway obstruction is an uncommon problem that is potentially life-threatening. The principal pathophysiological mechanism involved is the generation of markedly negative intrathoracic pressure, which leads to an increase in pulmonary vascular volume and pulmonary capillary transmural pressure, creating a risk of disruption of the alveolar-capillary membrane. We report the case of an adult male with diffuse alveolar hemorrhage following acute upper airway obstruction caused by the formation of a cervical and mediastinal abscess resulting from the insertion of a metallic tracheal stent. The patient was treated through drainage of the abscess, antibiotic therapy, and positive pressure mechanical ventilation. This article emphasizes the importance of including this entity in the differential diagnosis of acute lung injury after procedures involving upper airway instrumentation.
