Table 4.

Comparison of TAA-specific CTL in blood and tumor

Patient	Circulating TAA-specific CTL preceding vaccination	TAA-specific TIL
1	MART_26–35	gp100_154–162
2	All negative	MART_26–35
3	All negative	Tyrosinase_368–376
4	All negative	MART_26–35 + gp100_154–162
5	All negative	MART_26–35 + gp100_154–162
6	All negative	gp100_154–162
7	All negative	All negative
8	All negative	All negative

The table shows results of tetramer analyses in patients of which both blood and tumor tissue were available. Preceding vaccination therapy, in no patient CTL were found for the same TAA in both blood and tumor tissue
