OBJECTIVE: To determine the percentage of metastatic and unexpected residual lung cancer at autopsy in patients considered for curative resection of non-small cell lung cancer during a time when computed tomography was available as a preoperative staging tool. MATERIAL AND METHODS: Clinical data and surgical and autopsy slides of all patients who underwent curative resection of non- small cell lung cancer at the Mayo Clinic in Rochester, Minn, between 1985 and 1999 and who underwent autopsy within 30 days of surgery were reviewed retrospectively for the presence of residual or metastatic disease, RESULTS: The study group consisted of 25 men and 7 women, with a mean age of 70 years. A pulmonary metastasis was identified at surgery in 1 patient (3%). Metastases were found in an additional S patients (16%) at autopsy, 1 of whom had 2 sites involved. These sites included the liver in 2 and lung, epicardium, adrenal Sand, and kidney in 1 each. The average diameter of metastases was 1.6 cm. No factor studied was found to be significantly associated with the presence of unrecognized meta static disease at autopsy. CONCLUSION: The advent of computed tomography as a staging tool has decreased the percentage of patients with undiagnosed metastatic disease at surgery; however, preoperative understaging in lung cancer remains a problem.

    Lung cancer metastasis commonly involves the adrenal glands, liver, bone, and brain. However, it can have some rarer forms of metastatic presentation making diagnosis difficult, especially in nonsmokers. We describe a rare case of lung cancer with metastasis to the ischioanal fossa. Overall,...

    Background and Purpose: Positron-emission tomography/computed tomography (PET/CT) with fluorine-18 fluorodeoxyglucose (FDG) is used as first-line staging for patients with newly diagnosed non-small cell lung cancer (NSCLC). Our purpose was to review the accuracy of FDG-PET/CT to predict adrenal...

    Abstract: Objective: Lung segmentectomy reduces the extent of resection required for lobectomy, but its resulting clinical benefits remain controversial. Methods: Forty patients who underwent segmentectomy for stage I lung cancer over a 5-year period were matched to 40 patients who underwent...

    There are no accurate data on the diagnostic value of preoperative flexible bronchoscopy (FB) for persistent ground-glass nodule (GGN) of the lung. We evaluated the value of preoperative FB in patients with suspected GGN-type lung cancer. We retrospectively searched a database for subjects who...
