Among the patients that received BCG immunotherapy, more FAS homozygous patients had BCa recurrence than FAS polymorphism-negative patients (P < 0.001) and more patients with homozygote FASL polymorphisms had BCa recurrence than those with heterozygous FASL polymorphisms and no polymorphism.
Cell cycle (MDM2 and Cyclin D1) and apoptotic (Fas) genes that are differentially expressed in urinary bladder cancer (UBC) were investigated with the susceptibility to UBC in northern India.
This is the first report on the Fas gene mutations in nonlymphoid malignancies, and our data suggest that alterations of the Fas gene might lead to the loss of its apoptotic function and contribute to the pathogenesis of some bladder cancers.
