To detect prostate cancer in young black men and compare our results with those of western studies.
The authors conducted a prospective multicenter study from February 2008 to May 2009 on 220 men aged 40 to 49 years. All patients with an abnormal prostate suspicious of cancer and/or a PSA greater than 2.5 ng/ml had a prostate biopsy.
The mean age of patients was 44.99 years. The mean PSA was 26.62 ng/ml and ranged from 0.3 to 5600 ng/ml, with a median PSA of 0.88 ng/ml. Eleven patients had a PSA greater than 2.5 ng/ml and three had abnormal prostates suspicious of cancer. Twelve patients had a prostate biopsy. Histologic studies of the specimens found one case of prostate adenocarcinoma (Gleason 4+4) and two cases of high grade prostate intraepithelial neoplasia (HGPIN), all within the 46 to 50 years age group.
Due to the absence of prostate cancer within the 40 to 45 years age group, we would not recommend the screening of prostate cancer within this age group. This is only a preliminary study, and should be completed with the search for familial forms of prostate cancer. Also, a regular follow-up of patients already presenting with PSA greater than 2.5 ng/ml or HGPIN should be considered.
在年轻黑人男性中检测前列腺癌,并将我们的结果与西方研究结果进行比较。
作者于2008年2月至2009年5月对220名年龄在40至49岁的男性进行了一项前瞻性多中心研究。所有前列腺异常怀疑患有癌症和/或前列腺特异性抗原(PSA)大于2.5 ng/ml的患者均接受了前列腺活检。
患者的平均年龄为44.99岁。平均PSA为26.62 ng/ml,范围为0.3至5600 ng/ml,PSA中位数为0.88 ng/ml。11名患者的PSA大于2.5 ng/ml,3名患者的前列腺异常怀疑患有癌症。12名患者接受了前列腺活检。对标本的组织学研究发现1例前列腺腺癌(Gleason 4+4)和2例高级别前列腺上皮内瘤变(HGPIN),均在46至50岁年龄组内。
由于40至45岁年龄组内未发现前列腺癌,我们不建议在该年龄组进行前列腺癌筛查。这只是一项初步研究,应通过寻找前列腺癌的家族形式来完善。此外,应考虑对PSA已大于2.5 ng/ml或患有HGPIN的患者进行定期随访。
