PURPOSE Recent studies have suggested that specific single-nucleotide polymorphisms (SNPs) contribute to the clinical features of benign prostatic hyperplasia (BPH). In this study, we investigated the relationships of genetic polymorphisms of the epidermal growth factor (EGF) gene and the epidermal growth factor receptor (EGFR) gene with BPH. METHODS A total of 218 patients with BPH were enro...

OBJECTIVES To investigate the prognostic significance of undetectable ultrasensitive prostate-specific antigen (PSA) nadir in patients who received radical prostatectomy (RP) for prostate cancer. METHODS We reviewed records of 384 patients who received RP for prostate cancer and were followed for at least 2 years with ultrasensitive PSA testing. Undetectable ultrasensitive PSA level was defin...

OBJECTIVE To determine if there are significant differences in biochemical characteristics, biopsy variables, histopathological data, and rates of prostate-specific antigen (PSA) recurrence between African-American (AA) and white American (WA) men undergoing radical prostatectomy (RP), as AA men are twice as likely to die from prostate cancer than their white counterparts. PATIENTS AND METHOD...

In this retrospective study, we evaluated the chromogranin A (CgA) baseline value as a predictor of clinical outcome in patients with metastatic castration-resistant prostate cancer (CRPC) treated with abiraterone 1000 mg per day, whose disease progressed after docetaxel chemotherapy. In the 48 evaluable patients, serum CgA level was normal when <120  ng/ml (group A, n=16), within three times t...

BACKGROUND To evaluate prognostic factors in salvage radiotherapy (RT) for patients with pre-RT prostate-specific antigen (PSA) < 1.0 ng/ml. METHODS Between January 2000 and December 2009, 102 patients underwent salvage RT for biochemical failure after radical prostatectomy (RP). Re-failure of PSA after salvage RT was defined as a serum PSA value of 0.2 ng/ml or more above the postradiotherap...

Frameworks that associate cancer dynamic disease progression models with parametric survival models for clinical outcome have recently been proposed to support decision making in early clinical development. Here we developed such a disease progression clinical outcome model for castration-resistant prostate cancer (CRPC) using historical phase II data of the anticancer agent eribulin. Disease p...

OBJECTIVE To determine whether the rate of change in total serum prostate-specific antigen (PSA) levels accurately detects prostate cancer and to evaluate whether it adds any predictive value to a single measurement of serum PSA alone, in general practice settings. MATERIALS AND METHODS A retrospective cohort of 219,388 community-dwelling men, aged ≥45 years, enrolled in the Kaiser Permanente...

PURPOSE Prostate-specific antigen (PSA) has been used as a marker of advanced prostate cancer but remains controversial. To evaluate PSA as a predictor of survival, we analyzed data from sequential phase II trials of estramustine and etoposide. METHODS A landmark analysis that used data from 62 men with PSA levels at baseline and 8 weeks was conducted. The best PSA measure (of six evaluated) ...

BACKGROUND Rates of long-term survival among patients with untreated localized prostate cancer are high. To avoid unnecessary treatment, tools are needed to identify the small proportion of patients who are destined to develop lethal prostate cancer. METHODS To evaluate the accuracy of early changes in prostate-specific antigen (PSA) levels as predictors of prostate cancer outcome, we assesse...
