The current practice of pulmonary metastasectomy for head and neck cancers in our institution was well justified. A disease-free interval equal to or longer than 12 months, nonsquamous cell carcinoma, and female sex might be relevant to a better prognosis.

Our results confirmed that SLM nebulization during warm ischemia maintained lung tissue cAMP levels, resulting in the alleviation of pulmonary warm ischemia-reperfusion injury.

Current practice of pulmonary metastasectomy for colorectal carcinoma in our institution was well justified. Our study confirmed that unilateral pulmonary metastasis was significantly relevant to a better prognosis.

The treatment of metastatic renal cell carcinoma still represents a widely debated issue due to the introduction of several immunotherapies. To confirm again a role for resection of pulmonary metastases for such tumors, we reviewed our institutional experience. Between 1992 and 2007, eight patients with pulmonary metastases from renal cell carcinoma underwent complete pulmonary resection. All patients had undergone curative resection of their primary renal cell carcinomas and also had obtained or had obtainable locoregional control of their primaries. Various perioperative variables were investigated retrospectively. Disease-free interval varied from 25 to 156 months, with a median of 73 months. In three patients, lung metastases were found to be unilateral and solitary. Four patients presented two metastases in the unilateral lungs. One patient showed five metastases in the bilateral lungs. Six patients underwent wedge resection or segmentectomy, while two patients underwent more than lobectomy. Five patients showed recurrence after pulmonary metastasectomy. Five-year and 10-year overall survival rate was 83.3% and 41.7%, respectively, while 3-year and 5-year disease-free survival rate was 35.0% and 17.5%, respectively. Our study suggested that pulmonary metastasectomy for renal cell carcinoma might be well justified.

Pulmonary metastasectomy for hepatocellular carcinoma in selected patients was well justified when the maximum tumor size was <3 cm.
