Psa Failure

PURPOSE A multivariable analysis to evaluate the potential clinical and pathologic factors that predict for early biochemical failure in patients with pathologically organ-confined and margin-negative disease was performed to define patients who may benefit from adjuvant therapy. PATIENTS AND METHODS Three hundred forty-one prostate cancer patients treated with a radical retropubic prostatectomy between January 1989 and June 1995 and found to have pathologically organ-confined and margin-negative disease comprised the study population. A logistic regression multivariable analysis to evaluate the predictive value of the preoperative prostate-specific antigen (PSA) level, pathologic (prostatectomy) Gleason score, and pathologic stage on PSA failure occurring during the first postoperative year was performed. RESULTS Predictors of PSA failure during the first postoperative year in patients with pathologically organ-confined disease included pathologic Gleason score > or = 7 (P = .0007) and preoperative PSA level greater than 10 (P < .0001). Corresponding 3-year freedom-from-PSA-failure rates for these pathologic organ-confined patients with both, one, or neither of these factors were 60%, 75% to 84%, and 95%, respectively (P < .0001). CONCLUSION Prostate cancer patients with pathologically organ-confined and margin-negative disease and a preoperative PSA level greater than 10 ng/mL or a pathologic Gleason score > or = 7 have significant decrements in short-term PSA-failure-free survival. Therefore, these patients should be considered for adjuvant therapy in the setting of a phase III clinical trial.

14621 Background: After undergoing definitive treatment for a primary localized disease, prostate cancer patients may experience a rise in their prostate specific antigen (PSA) levels. Treating PSA failure with hormonal treatment has many health related quality of life (HRQOL) implications, including urinary, bowel, sexual, and male hormonal problems. Predictors of choice between hormonal treatment versus watchful waiting have not been investigated. Methods: Patients were approached after consecutive rises in PSA levels (n = 31). Patients completed HRQOL and decision satisfaction questionnaires, and a literacy assessment. Results: Patients were between 56 and 85 years old; 55% were African American. 71% of African Americans and 50% of whites had low functional literacy. 58% of patients chose hormonal therapy to treat their PSA rise; 81% of patients reported urinary problems. All patients reported decision satisfaction (see Table). Factors associated with castration versus watchful waiting were primarily related to poor urologic function, and were not specifically prostate cancer related (dysuria, nocturia, urination frequency). Conclusions: Primary treatment of urinary dysfunction, rather than castration, should be evaluated as initial therapy for prostate cancer patients with PSA failure.

Lhrh Therapy

9093 Background: Growing numbers of prostate cancer patients survive for extended periods of time after initial diagnosis and treatment. Many experience a biochemical relapse (“PSA failure”) some time after prostatectomy or pelvic radiation. LhRH agonist therapy can reduce PSA levels, but its impact on survival time and quality of life (QOL) is unclear. We evaluated these concerns among Veterans who experienced PSA Failure. Methods: Eligibility criteria included: receipt of primary therapy for prostate cancer followed by a PSA nadir and subsequent PSA rise to at least 0.2 ng/ml. Data sources include patients (interviewer administered survey instruments on health-related QOL at baseline, 3 and 12 months) and medical records (clinical and laboratory findings). Results: 69 patients from the Jesse Brown VA Medical Center in Chicago have enrolled in the study to date. At their baseline interviews, 30 patients (43.5%) were receiving LhRH agonists (46.1% of 39 African-American patients and 48.0% of 25 White patients). LhRH agonist patients reported worse health-related QOL in domains relevant to prostate cancer than watchful waiting (WW) patients ( Table ), including increased frequency of urination, difficulty controlling urination, greater erectile dysfunction, and more limits on sexual activity. LhRH agonist and WW patients reported similar levels of sexual satisfaction. Conclusion: Of the PSA failure patients studied in this sample, those receiving LhRH agonist therapy experience more problems with urinary and sexual function than those who opted for WW. Longitudinal study will provide information about whether the LhRH therapy causes these side effects, or whether symptomatic patients are more likely to choose LhRH therapy than those with few prostate cancer symptoms.

Core Genes

Prostate cancer is currently associated with higher morbidity and mortality in men in the United States and Western Europe, so it is important to identify genes that regulate prostate cancer. The high-dimension gene expression profile impedes the discovery of biclusters which are of great significance to the identification of the basic cellular processes controlled by multiple genes and the identification of large-scale unknown effects hidden in the data. We applied the biclustering method MCbiclust to explore large biclusters in the TCGA cohort through a large number of iterations. Two biclusters were found with the highest silhouette coefficient value. The expression patterns of one bicluster are highly similar to those found by the gene expression profile of the known androgen-regulated genes. Further gene set enrichment revealed that mitochondrial function-related genes were negatively correlated with AR regulation-related genes. Then, we performed differential analysis, AR binding site analysis, and survival analysis on the core genes with high phenotypic contribution. Among the core genes, NDUFA10 showed a low expression value in cancer patients across different expression profiles, while NDUFV2 showed a high expression value in cancer patients. Survival analysis of NDUFA10 and NDUFV2 demonstrated that both genes were unfavorable prognostic markers.

e16083 Background: Growing numbers of prostate cancer patients experience biochemical relapse (PSA failure) after initial treatment. LhRH agonist (hormonal) therapy can reduce PSA levels, but there is no clear evidence that it slows disease progression or reduces mortality. Quality of Life (QoL) issues are essential when deciding between observation (OBS) versus hormonal castration following biochemical relapse. We evaluated health related quality of life and treatment satisfaction among prostate cancer patients who experience PSA failure. Methods: Eligibility criteria were receipt of primary therapy for prostate cancer followed by a PSA nadir and subsequent PSA rise to at least 0.2 ng/ml. Data sources include medical records and interviewer administered surveys on health- related QoL at baseline, 3 and 12 months. Results: Castrated versus observed patients who are satisfied with their sexual activity report similar health-related QoL, with the exception of higher rates of maintaining an erection (73.3% vs. 32.0%) and not having prostate cancer affect sexual activity (66.7% vs. 28.6%). Castrated and expectant management patients with low levels of satisfaction and sexual activity report similar health-related QoL. Conclusions: Among patients with PSA Failure, the only health-related QOL difference is reflected in sexual activity related to erectile dysfunction, but not sexual satisfaction among patients who all have a high level of treatment decision satisfaction and sexual activity.
