With the increasing incidence of prostate cancer, identifying common genetic variants that confer risk of the disease is important. Here we report such a variant on chromosome 8q24, a region initially identified through a study of Icelandic families. Allele −8 of the microsatellite DG8S737 was associated with prostate cancer in three case-control series of(More)
OBJECTIVES Patients and referring physicians often ask about the significance of lymphovascular invasion (LVI) on pathology reports from radical prostatectomy specimens. However, limited data are available concerning the relationship between LVI and preoperative screening characteristics, pathologic tumor features, and patient prognosis. METHODS LVI was(More)
PURPOSE A prostate specific antigen velocity threshold of 0.75 ng/ml per year has commonly been used to distinguish men with prostate cancer from those with benign prostate conditions. In addition, a prostate specific antigen velocity greater than 2 ng/ml per year has been linked to an increased prostate cancer specific mortality rate after radical(More)
PURPOSE There are numerous reports on the results of watchful waiting or active monitoring protocols for men with low volume, biopsy Gleason grade 6 or less prostate cancer. When counseling patients with low grade prostate cancer about treatment options, it is useful to know the results of surgical treatment in this population. MATERIALS AND METHODS In a(More)
OBJECTIVES Since the initiation of prostate-specific antigen (PSA) screening, the progression-free survival (PFS) rates after radical prostatectomy have markedly improved. However, few studies have evaluated whether PFS has improved for stage and grade-matched patients. Our objective was to examine differences in PFS after radical prostatectomy between the(More)
OBJECTIVES No consensus has been reached about the optimal follow-up for patients with an isolated finding of high-grade prostatic intraepithelial neoplasia (HG-PIN) on prostate biopsy. Early studies reported that approximately one half of men with HG-PIN were diagnosed with prostate cancer (CaP) within a few years. However, more recent studies, using(More)
PURPOSE Prostate specific antigen velocity is frequently calculated using regression analysis of multiple prostate specific antigen measurements during an interval of 18 to 24 months. It has been reported that the prostate specific antigen velocity in the year before prostate cancer diagnosis is associated with the cancer specific mortality rate following(More)
PURPOSE We quantified the rates of over and under diagnosis of prostate cancer in 2 large patient cohorts during the last 15 years. MATERIALS AND METHODS A total of 2,126 men with clinical stage T1c prostate cancer were treated with radical prostatectomy during 1 of the 3 periods 1989 to 1995, 1995 to 2001 and 2001 to 2005. The respective proportions of(More)
PURPOSE Postoperative prostate specific antigen doubling time may be used as a surrogate for prostate cancer specific mortality in patients with biochemical recurrence after radical prostatectomy. Less is known about the usefulness of preoperative prostate specific antigen doubling time for the initial prediction of prostatectomy outcomes. MATERIALS AND(More)
OBJECTIVES For prostate cancer screening, the role of prostate-specific antigen (PSA) velocity (PSAV) in conjunction with total PSA is controversial. We evaluated the relationship of PSAV to histologic findings on biopsy and assessed whether PSAV provides independent predictive information. METHODS From a community-based cohort of 25,276 men screened from(More)
