Purpose: Review the epidemiology, etiology and results of surgical management of mediastinal masses in New Mexico. Methods: A review of all surgically managed mediastinal masses at the University of New Mexico, the Albuquerque VA Medical Center, and the Albuquerque Lovelace Hospital between June 1992 and May 1996. Results: 18 patients were treated. 11 were male. Median age was 36 years (range 18 to 82). 50% were Hispanic, 33% White, 11% Native American, and 6% Black. In New Mexico the population is 39% Hispanic, 50% White, 9% Native American, and 2% Black. 56% of tumors were benign, 44% malignant. 75% of malignant tumors were in Hispanics, 0% in Whites, 13% in Native Americans, and 13% in Blacks. 30% of benign tumors were in Hispanics, 60% in Whites, 10% in Native Americans, and 0% in Blacks (p=0.03 Fishers Exact test; p=0.04 adjusting for age, Mantel-Haenszel, malignancy, Hispanics vs Whites). Symptoms occurred in 83%, and in 88% with malignancy. 72% had resection, 28% had biopsies. 72% of tumors were in the anterior mediastinum, 54% of these were malignant. 33% of tumors were in the posterior mediastinum, 83% of these were benign. 1 patient had benign cysts in both compartments. 54% had sternotomy, 31% had throracotomy, 15% had thoracoscopy. Complications occurred in 22%. There were no operative deaths. Conclusions: Many tumors in the anterior mediastinum are malignant. Malignancy is more common in Hispanics compared to Whites. Surgery has low morbidity and mortality rates. Clinical Implications: 44% of mediastinal masses are malignant. Malignancy is more common in Hispanics. Surgery is safe.
