Increased incidence of oropharyngeal squamous cell carcinomas after liver transplantation for alcoholic cirrhosis.
BACKGROUND
THE aim of this study was to describe the features of posttransplantation tumors observed in a series of liver transplant recipients with special reference to patients receiving a transplant for alcoholic cirrhosis.


METHODS
Among 171 consecutive liver transplant recipients, 90 patients who had received a first liver allograft for cirrhosis were studied. After liver transplantation, detection of de novo malignancies was prospectively undertaken and the characteristics of the patients in whom tumors occurred were compared with those in whom tumors did not develop.


RESULTS
With a follow-up of 45.2+/-21.2 months, 11 tumors were observed in 90 patients (overall incidence of 12.2%). The incidence of tumors was higher in patients receiving a transplant for alcoholic cirrhosis than in patients receiving a transplant for nonalcoholic cirrhosis (26.7% vs. 5.0%, P<0.01). Squamous cell carcinoma (SCC) of the oropharynx or esophagus and posttransplant lymphoproliferative disorders were mainly observed. SCC (uvula in two cases, tongue in one case, esophagus in one case, pharynx in one case) occurred exclusively in patients transplanted for alcoholic cirrhosis (16.7% vs. 0%, P=0.001). The incidence of posttransplant lymphoproliferative disorders was similar in alcoholics and nonalcoholics (6.7% vs. 5%, NS). Survival was not influenced by the occurrence of SCC.


CONCLUSIONS
The incidence of oropharyngeal SCC could be high in patients receiving a transplant for alcoholic cirrhosis. This could be due to an additional effect of posttransplantation immunosuppression in patients exposed to alcohol and tobacco before transplant. Careful posttransplantation screening of oropharyngeal SCC is warranted after liver transplantation for alcoholic cirrhosis.
