Endotracheal metastases from colon adenocarcinoma.

Endotracheal metastases (ETM) from non-lung cancer are seldom seen. Their main clinical symptoms are cough, haemoptysis and dyspnoea, although occasionally an incidental finding is made during a bronchoscopy. Breast, colon and kidney adenocarcinoma might be associated with ETM, lung cancer being the most frequent cause. Its finding is associated with advanced disease but survival will depend on the primary origin, patient status and comorbidity. Therefore, treatment should be individual for each patient. In our centre we recommend pre-surgery bronchoscopy to exclude metastatic endotracheal lesions in patients with metastatic colon adenocarcinoma disease, as this might affect the final outcome and therefore management of the disease.

[Computed tomography-guided radiofrequency ablation of malignant lung lesions: early experience]. / Ablación mediante radiofrecuencia guiada por tomografía computarizada de las lesiones pulmonares malignas: experiencia inicial.

OBJECTIVE: To present our early experience in the treatment of primary malignant and metastatic lung lesions by radiofrequency ablation. PATIENTS AND METHODS: From August 2004 through January 2007 we treated 19 patients (in 26 procedures) with curative or palliative intent. None of the lesions was amenable to surgery and some had been treated previously. The procedure was performed in the radiology room under conscious sedation-analgesia administered by an anesthesiologist. Fourteen patients were treated for pulmonary lesions and 5 for metastatic lung disease in a context of controlled primary disease. Treatment was with curative intent in 15 cases and palliative in 4. RESULTS: The radiofrequency technique was applicable in 26 procedures and the mean follow-up was 8.68 months. The principal complications of radiofrequency treatment were pneumothorax in 4 patients, requiring drainage in only 2 cases; pneumonitis in 4; self-limiting pulmonary hemorrhage in 1; and pleural effusion in 5. There were no procedure-related deaths. Six patients died during the follow-up period. CONCLUSIONS: In our experience, radiofrequency offers a safe and minimally invasive option for the treatment of malignant lung lesions in appropriately selected, nonsurgical patients. Morbidity is low, and in combination with other treatments this technique opens up a wide range of possibilities still to be explored.
