title: [De novo tumors in adult patients with hepatic transplant].
abstract: The incidence of de novo neoplasms was analyzed in 340 patients with liver transplantation who survived more than 2 months post transplantation. Sixteen (4.7%) patients developed a new tumor following transplantation. The most frequent tumor observed was a lymphoma which was detected in four patients (1.2%). In three of the four lymphomas histologic diagnosis of non Hodgkin phenotype B lymphoma was confirmed and in three patients the central nervous system was involved. The remaining tumors consisted of two cases of adenocarcinoma of the colon, papillary carcinoma of the urinary bladder and ductal breast cancer (0.6%) for each of these tumors and one case of cervical cancer, adenocarcinoma of the small intestine, Kaposi sarcoma, laryngeal carcinoma, pharyngeal carcinoma and malignant melanoma (0.3% for each tumor). None of the patients developed more than one tumor. The mean time to the appearance of the tumors was 28 months (range: 3-52 months). These results suggest that de novo neoplasms in patients with liver transplantation are relatively frequent, particularly lymphoma.
