The incidence of erectile dysfunction (ED) in men following radical prostatectomy has been estimated to range from 16% to 82%. Several factors determine the postoperative incidence of erectile difficulties; these include patient age, degree of cavernosal nerve sparing during surgery, cancer stage, and associated comorbidities. Early initiation of available treatments after radical prostatectomy, such as phosphodiesterase-5 (PDE-5) inhibitors and intracavernosal alprostadil, may improve the speed and degree of recovery of erectile function. Oral PDE-5 inhibitors are recognized as the first line of therapy for men with ED after radical prostatectomy, with reasonable success rates reported for all commercially available PDE-5 inhibitors. In recognition of the neurogenic basis for erectile dysfunction after radical prostatectomy, new strategies have been devised, such as cavernous nerve graft interposition procedures, perioperative neuroprotection measures, and postoperative neurotrophic treatments. Hopefully, these efforts will improve quality of life for patients with prostate cancer. The aim of this article is to review the current modalities of ED management for men with prostate cancer.</p></div>","PeriodicalId":87076,"journal":{"name":"Clinical prostate cancer","volume":"3 2","pages":"Pages 87-92"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3816/CGC.2004.n.017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40915596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to evaluate prospectively preferences, optimism, involvement in care, and quality of life (QOL) in black and white veterans newly diagnosed with localized prostate cancer. A total of 95 men who identified themselves as black/African-American or white who had newly diagnosed, localized prostate cancer completed a \"time trade-off\" task to assess utilities for current health and mild, moderate, and severe functional impairment; importance rankings for attributes associated with prostate cancer (eg, urinary function); and baseline and follow-up measures of optimism, involvement in care, and QOL. Interviews were scheduled before treatment, and at 3 and 12 months after treatment. At baseline, both blacks and whites ranked pain, bowel, and bladder function as their most important concerns. Optimism, involvement in care, and QOL were similar. Utilities for mild impairment were lower for blacks than whites, but were similar for moderate and severe problems. Decline in QOL at 3 and 12 months compared to baseline occurred for both groups. However, even with adjustment for marital status, education level, and treatment, blacks had less increase in nausea and vomiting and more increase in difficulty with sexual interest and weight gain compared with whites. Black and white veterans entered localized prostate cancer treatment with similar priorities, optimism, and involvement in care.

Increased Hsp70 expression is reported in a variety of tumor tissues. Heat shock protein 70 is detectable in plasma and could potentially be used as a biomarker for diagnosis or disease stratification. The relationship between plasma levels of Hsp70 and prostate cancer status has not been well studied. Our study was designed to test this relationship. One hundred twenty-five patients with localized/untreated or hormone-refractory prostate cancer were identified. Forty-five healthy male blood donors between 50 and 73 years of age served as controls. EDTA plasma was subjected to quantitative sandwich immunoassays for both Hsp70 and prostate-specific antigen (PSA). Wilcoxon rank-sum tests were used to examine differences by category. Maximally selected χ² statistics were used to identify cutoff points to best distinguish between categories. Plasma Hsp70 levels in the patients with localized untreated disease (n = 68; median, 0.8 ng/mL; interquartile range, 0.5-2.0) were significantly higher than those in the control group (n = 45; median, 0.5 ng/mL; interquartile range, 0.3-0.8; <em>P</em> = 0.0037). Although the primary cutoff point (1.15 ng/mL) significantly distinguished the localized untreated patients from the control group, plasma Hsp70 levels did not prove more effective than PSA as a predictor for diagnosis or stratification of patients with prostate cancer in the context of group comparisons. Nonetheless, several patients in the localized untreated group showed higher plasma levels of Hsp70 than the primary cutoff point even though their PSA levels were within normal range (&lt; 4 ng/mL). Heat shock protein 70 is a marker of prostate cancer, although its clinical utility is uncertain. It is possible that when used in conjunction with PSA it might prove useful in identifying patients with early-stage prostate cancer who might otherwise be missed by PSA screening alone.</p></div>","PeriodicalId":87076,"journal":{"name":"Clinical prostate cancer","volume":"3 1","pages":"Pages 49-53"},"PeriodicalIF":0.0,"publicationDate":"2004-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3816/CGC.2004.n.013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40948344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
