This study analyzes ten cases of malignancy in a cohort of 183 renal transp
lant recipients, examining surgical management, postoperative immunosuppres
sive therapy, and long-term outcome. One of these ten patients, who had mal
ignant lymphoma of the jejunum, died of the neoplasm, but the other nine pa
tients did not show any signs of tumor recurrence after removal. All of the
se nine patients, except for one who had transplant renal cell carcinoma (R
CC), received the same dose of immunosuppressive agents after surgery for t
he malignant disease. Seven patients were still alive at the time of this r
eport, six of whom had good transplant renal function. The findings of this
study indicate that even if immunosuppressive agents predispose to the dev
elopment of cancer, it is not necessary to reduce their dose after removal
of the tumor.
