	abstract = {In a series of 10151 organ allograft recipients who developed 10813 de novo malignancies after transplantation, 755 involved the hepato-biliary-pancreatico-duodenal (HBPD) area. If nonmelanoma skin cancers and in situ carcinomas of the uterine cervix were excluded (as they are from most cancer statistics), then the HBPD area was affected by 10\% of neoplasms. Many of the tumors encountered were uncommon in the general population. The largest group of neoplasms was 474 lymphomas, which comprised 63\% of the total. Other major malignancies were hepatocellular carcinomas (HCC; 15\%), pancreatic carcinomas (11\%), cholangiocarcinomas (3\%), Kaposi{\textquoteright}s sarcomas (3\%), and other sarcomas (1\%). Lymphomas occurred at a younger age than other tumors (average, 39 versus 50 years), appeared earlier after transplantation (average, 24 versus 77 months), and were more frequently associated with immunosuppressive therapy with the antilymphocytic agents (ALG/ATG) and/or (OKT3) (59\% versus 28\%). Lymphomas were localized to the HBPD area in only 18\% of patients, whereas in 82\% there was involvement of other organs or sites. The liver was involved in 95\% of lymphomas. Lymphomas frequently involved allografts, the liver in 84\%, and the pancreas in 59\%. Of 292 patients treated for lymphomas 67 (23\%) had complete remissions lasting 6 months or more. HCC was frequently associated with hepatitis B or C infection. Kaposi{\textquoteright}s sarcomas were rarely confined to the HBPD area, and in 25\% of cases there were no associated skin lesions. An unusual subset of tumors were leiomyosarcomas involving hepatic allografts of pediatric patients. The poor prognosis of most tumors in this series may be related to delays or problems in making the diagnosis in these immunosuppressed patients and, perhaps, it may also be related to the unusually aggressive behavior of some tumors.},
