Abstract

Purpose: The initial goal of this study was to test the immunologic and clinical effects of a new cancer vaccine consisting of dendritic cells (DC) transduced with the full-length wild-type p53 gene delivered via an adenoviral vector in patients with extensive stage small cell lung cancer. Experimental Design: Twenty-nine patients with extensive stage small cell lung cancer were vaccinated repeatedly at 2-week intervals. Most of the patients received three immunizations. p53-specific responses were evaluated, and phenotype and function of T cells, DCs, and immature myeloid cells were analyzed and correlated with antigen-specific immune responses. Objective clinical response to vaccination as well as subsequent chemotherapy was evaluated. Results: p53-specific T cell responses to vaccination were observed in 57.1% of patients. Immunologic responses to vaccination were positively associated with a moderate increase in the titer of antiadenovirus antibodies, and negatively with an accumulation of immature myeloid cells. One patient showed a clinical response to vaccination whereas most of the patients had disease progression. However, we observed a high rate of objective clinical responses to chemotherapy (61.9%) that immediately followed vaccination. Clinical response to subsequent chemotherapy was closely associated with induction of immunologic response to vaccination. Conclusions: This study provides clinical support for an emerging paradigm in cancer immunotherapy, wherein optimal use of vaccination might be more effective, not as a separate modality, but in direct combination with chemotherapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
