PURPOSE The American Urological Association Prostate Guideline Update Panel was charged with updating the Guidelines for Clinically Localized Prostate Cancer. In assessing outcomes with treatment, it became apparent that a highly variable number of definitions exist with respect to biochemical recurrence. Herein, we review the variability in published(More)
Elevated levels of the p53 protein occur in approximately 50% of human malignancies, which makes it an excellent target for a broad-spectrum T cell immunotherapy of cancer. A major barrier to the design of p53-specific immunotherapeutics and vaccines, however, is the possibility that T cells may be tolerant of antigens derived from wild-type p53 due to its(More)
PURPOSE Studies suggest that SNPs within ESR1 may be associated with an increased risk of prostate cancer. We evaluated the association of the XbaI and PvuII ESR1 SNPs and prostate cancer risk in 3 different racial/ethnic populations. MATERIALS AND METHODS A total of 1,603 volunteers from the SABOR study (285 black, 876 white and 442 Hispanic men) were(More)
A high proportion of tumors arise due to mutation of the p53 tumor suppressor protein. A p53 hotspot mutation at amino acid position 273 from R to H, flanking a peptide epitope that spans residues 264-272, renders cells resistant to killing by human histocompatibility leukocyte antigen (HLA)-A*0201-restricted cytotoxic T lymphocytes (CTLs) specific for this(More)
PURPOSE Since 1988, scientists from the Central Valley Regional Water Quality Control Board have tested water quality in the San Joaquin River watershed using toxicity tests. They found that water samples from certain areas of the watershed caused mortality in a species of water flea (Ceriodaphnia dubia). Ceriodaphnia dubia is used in these toxicity tests(More)
PURPOSE Hormonal therapy (HT) is the current mainstay of systemic treatment for prostate specific antigen (PSA) only recurrence (PSAR), however, there is virtually no published literature comparing HT to observation in the clinical setting. The goal of this study was to examine the Department of Defense Center for Prostate Disease Research observational(More)
Not all T cells specific for autoantigens are eliminated in the thymus, and therefore alternate mechanisms are required to prevent potentially autoreactive T cells from developing into effectors. Adoptive transfer of CD8(+) T cells from influenza hemagglutinin-specific Clone 4 TCR transgenic mice into mice that express hemagluttinin in the pancreatic islets(More)
BACKGROUND The widespread use of prostate-specific antigen (PSA) screening has had a tremendous impact on all aspects of the management of prostate carcinoma. Although PSA-based screening has resulted in a stage migration to more organ-confined tumors at the time of diagnosis, and has been temporally associated with a decrease in prostate carcinoma(More)
OBJECTIVE To modify the Prostate Cancer Prevention Trial risk calculator (PCPTRC) to predict low- vs high-grade (Gleason grade≥7) prostate cancer and incorporate percent free-prostate-specific antigen (PSA). METHODS Data from 6664 Prostate Cancer Prevention Trial placebo arm biopsies (5826 individuals), where prostate-specific antigen and digital rectal(More)
