Dual IFNγ/IL2 response after stimulation by one peptide or a pool of peptide was observed in women F#2 (peptide 68–82), who entered the study after tumor treatment and in women F#3 (pool E2-5), F#6 (pool E2-11 and peptide 335–350) and F#8 (peptide 301–315) at the time of the clearance of their lesion. This evidence concerns the gene IFNG and neoplasm.
