Abstract
Evaluation of: Gulley JL, Arlen PM, Madan RA et al.: Immunologic and prognostic factors associated with overall survival employing a poxviral-based PSA vaccine in metastatic castrate-resistant prostate cancer. Cancer Immunol. Immunother. 1, 27–29 (2009). A comparison was made using an established prognostic nomogram to determine the impact of survival on patients with castration-resistant prostate cancer using a pox-based vaccine. Survival in the treated cohort of 32 patients had improved compared with what was anticipated for the same group using an established nomogram. With a median follow-up of 44.6 months, the median overall survival for all 32 patients in the study was 26.6 months compared with a median nomogram-predicted survival of 17.4 months. The data suggested that there may be measures by which patients may be preselected and therefore may be more responsive candidates to a vaccine treatment approach. This study brings to light improved survival for patients, but the issue of how to reconcile a survival advantage in the absence of significant clinical anti-tumor response remains unsettled.
