Epidermal growth factor receptor gene

More recently, there has been some exciting new information indicahng that the patients whose tumors clearly and in some cases dramatically responded to Iressa have achvating mutations and other mutations in the epidermal growth factor receptor gene in their tumorsd This finding has very imporfant implicahons whether pahents tumors should be evaluated for these types of mufafions before patients are plac on Iressa. Only additional studies will define fhaf future for Iressa.
