目的分析前列腺癌根治术(RP)后生化复发(BCR)的危险因素。方法回顾性分析2012年3月至2016年12月在郑州大学第一附属医院接受RP的241例患者的临床信息和随访资料。以随访过程中连续2次前列腺特异抗原(PSA)≥0.2μg·L~(-1)为BCR诊断标准。根据RP后是否发生BCR,将患者分为复发组(93例)和非复发组(148例)。比较两组患者相关参数,运用Cox回归模型进行多因素分析。结果两组术前PSA水平、术前Gleason评分、术后Gleason评分、临床分期、病理分期、精囊侵犯率、切缘阳性率及淋巴结转移率比较,差异有统计学意义(均P<0.05)。Cox多因素回归分析显示,术前PSA>20μg·L~(-1)、精囊侵犯、切缘阳性、淋巴结转移、术前Gleason评分>7分均是RP后BCR的独立危险因素(均P<0.05)。结论术前PSA>20μg·L~(-1)、术前Gleason评分>7分、精囊侵犯、淋巴结转移及切缘阳性均是RP后发生BCR的独立危险因素。 相似文献

目的 探究ROCK2蛋白在临床局限性前列腺癌患者肿瘤组织内部不同区域的表达水平及其意义。方法选取2005年1月至2010年12月行前列腺癌根治术的32例临床局限性前列腺癌患者,其中17例生化复发,15例至末次随访无生化复发。收集记录患者的前列腺特异抗原(prostate specific antigen, PSA)水平、Gleason评分、肿瘤分期及是否复发等资料。对这些前列腺根治标本进行免疫组化检测,评估肿瘤中心区、肿瘤前缘区及癌旁前列腺组织中ROCK2的表达水平,分析其与患者血PSA、肿瘤分期、分级及复发的关系。结果 ROCK2在前列腺癌组织肿瘤前缘区表达显著高于肿瘤中心区,且肿瘤前缘区ROCK2高表达与前列腺癌病理分级及生化复发相关,而肿瘤中心区ROCK2表达与前列腺癌病理分级及生化复发无相关。ROCK2表达与患者PSA水平及病理分期均无相关。结论ROCK2在前列腺癌前缘组织中高表达与肿瘤恶性程度及复发相关,该蛋白可能是前列腺癌的预后因子。 相似文献

目的:评价腹腔镜下前列腺癌根治术治疗早期前列腺癌的临床疗效。方法:1999年3月-2006年12月我院收治的26例早期前列腺癌患者,分为A组和B组。A组,20例患者,行开放性耻骨后前列腺癌根治术;B组,6例患者,行腹腔镜前列腺癌根治术。观察比较两组患者的围手术期情况、术中及术后早期并发症、术后随访生化复发及尿控的恢复情况。结果:所有患者手术均成功。两组患者的手术时间、出血量、切缘阳性率、术后病理分期、术中及术后早期并发症发生率、术后生化复发及尿控恢复情况比较均无明显差别;但B组患者术后住院时间明显短于A组患者(P〈0.05)。结论:腹腔镜前列腺癌根治术治疗早期前列腺癌可行;同开放性耻骨后前列腺癌根治术比较,损伤小、恢复快、住院时间短;在控制肿瘤和术后尿控功能恢复方面近期效果相当。 相似文献

为了了解增殖细胞核抗原(PCNA)与前列腺癌的病理分级、临床分期及预后的关系,我们采用免疫组织化学S-P法对43例前列腺癌组织中PCNA进行检测,并与临床随访结果进行对比。结果显示:前列腺癌PCNA表达与分级、分期及预后均呈正相关(P〈0.05),随肿瘤分级增高,PCNA表达明显上升趋势;肿瘤高分期组(Ⅲ、Ⅳ)的PCNA表达明显高于低分期组(Ⅰ、Ⅱ);PCNA高表达组(Ⅲ、Ⅳ极)术后生存率明显低于 相似文献

目的 探讨转谷氨酰胺酶4(transglutaminase 4, TGM4)在前列腺癌诊断及预后评价中的可能价值。 方法 对159例前列腺癌患者的存档石蜡标本行TGM4免疫组织化学染色;根据染色情况将TGM4表达水平分为4级:不表达,弱表达,中表达和高表达。通过查阅病历、调用我院前列腺癌随访数据库和电话随访等方式获得患者临床病理资料及随访信息;进而对TGM4表达水平与前列腺癌临床病理特征及预后信息的关系进行统计学分析。 结果 与癌旁组织相比,TGM4在前列腺癌组织中高表达(P<0.001),且表达水平在不同Gleason分级(P<0.001)和前列腺特异抗原(PSA)水平(P=0.005)间差异有统计学意义。单因素Cox回归分析提示TGM4高表达是前列腺癌生化复发的高危因素(P=0.020),但多因素Cox回归分析并不支持TGM4高表达是前列腺癌生化复发的高危因素(P=0.139)。 结论 TGM4在前列腺癌中高表达,且在高Gleason分级和高PSA水平的前列腺癌中表达更高,值得进一步研究。 相似文献

目的:探讨PIM-1蛋白在前列腺癌组织中的表达及其与PSA复发之间的关系.方法:利用免疫组化SP检测68例前列腺癌和37例良性前列腺增生(BPH)组织中PIM-1蛋白的表达.结果:在前列腺癌组织中PIM-1蛋白表达的阳性率为67.65% (46/68);BPH组织中40.54% (15/37),两组表达的差异有显著意义(P<0.05).PIM-1蛋白表达的阳性率在前列腺癌Gleason分级中6分33.33% (7/21),7分75%( 21/28),8~10分94.74% (18/19),组间比较差异有显著性(P<0.05).临床分期中在Ⅰ、Ⅱ、Ⅲ、Ⅳ期PIM-1蛋白表达率分别为47.62%、53.85%、73.33%、94.74%,36个月随访PSA复发状况采用Kaplan-Meier方法分析,PIM-1蛋白表达与有无复发分别是78.26% (36/46)和45.45%(10/22),差异有显著性(P<0.05).结论:前列腺癌中PIM-1蛋白表达与前列腺癌的Gleason分级、临床分期以及PSA复发有密切关系,提示PIM-1基因在前列腺癌演化和进展中有重要作用,可能是前列腺癌的预后指标. 相似文献

For localized prostate cancer, radiation therapy (RT) is commonly used. However, in the first five years of RT, 10%-20% of localized prostate cancer patients, ano 30%-50% of the locally advanced prostate cancer patients will progress to biochemical recurrence. In the past, only few these patients considered salvage radical prostatectomy (SRP) as their primary selection due to the significant morbidity. 相似文献

近年来人群中肥胖的比例不断上升,而肥胖与多种恶性肿瘤的发生、发展和死亡呈正相关,其中包括前列腺癌。前列腺癌是老年男性中高发的恶性肿瘤,目前有研究表明肥胖会导致前列腺癌的发生率及死亡率升高,并且认为肥胖与前列腺癌患者在接受根治性前列腺切除术后生化复发呈正相关。但也有部分研究认为两者之间无统计学意义上的相关性。本文通过回顾国内外以体质指数(body mass index,BMI)为指标和随访观察有无生化复发的研究文献,探讨肥胖与根治性前列腺切除术后前列腺癌生化复发的关系。 相似文献

Background Incidence of prostate cancer has been increasing in recent decades. In the year 2005, prostate cancer became the second most common cancer in males in Macau. The purpose of this report was to review and summarize the clinical features and prognosis of the 54 patients undergoing radical prostatectomy in Macau Special Administrative Region (SAR), China.
Methods From November 2000 to November 2006, retropubic radical prostatectomy were performed in 54 cases for the treatment of prostate cancer. The mean age of patients was 69.8 years (range from 54 to 79). The preoperative prostate specific antigen (PSA) level, postoperative pathologic stage and Gleason's score, operation duration, intraoperative bleeding and intraoperative and postoperative complications were reported. The follow-up duration was 3 months to 6.25 years with a mean of 2.1 years. Postoperative parameters including PSA alteration, biochemical recurrence, local recurrence, distant metastasis and mortality were observed.
Results Most of the patients in our study were diagnosed as localized prostate cancer. The patients' preoperative serum PSA was 0-4.0 ng/ml (16.7%), 4.0-10.0 ng/ml (51.8%), 10.1-20.0 ng/ml (24.1%) and above 20.0 ng/ml (7.4%). The TNM stage T1a + T1b comprised 7.6% of patients, stage T2a + T2b comprised 20.3%, stage T2c 38.9%, stage T3a 20.3% and over T3a only 12.9%. There were 9.5% cases with Gleason scores of 2-4, 41.5% with scores of 5-6, 30.2% with scores of 7 and 18.8% with scores of 8-10. The average operative duration was 216 minutes and the average intraoperative bleeding was 760 ml. Intraoperative complications included one massive hemorrhage (1.9%), one rectal injury (1.9%) and one obturator nerve injury (1.9%). Early postoperative complications consisted of urinary incontinence (14 cases, 25.9%), bladder neck stricture (5 cases, 9.3%), acute urinary retention (4 cases, 7.4%), pelvic effusion (2 cases, 3.8%), lymphocele (1 case, 1.9%) and vesicorect 相似文献
