Intratumoral vaccination induces objective clinical responses. (A) Patients received 2 Gy × 2 radiation combined with intratumoral injection of PF-3512676 to a single disease site and disease was measured at up to six distant sites. (B) Waterfall plot showing percent change in the cross-product sum at the time of best response (indicated above ordinate) versus pretreatment. (*) Refers to patient 10, whose primary cutaneous disease was instead measured as a three-dimensional sum. SPD, sum of products of greatest diameter.
