J Clin Oncol:兄弟间非低风险前列腺癌的一致性

2018-04-15 海北 MedSci原创

最近,来自瑞典的研究人员进行了一项研究,调查了兄弟间非低风险前列腺癌的一致性如何受遗传关系的影响。

一级亲属患有前列腺癌是诊断前列腺癌的强大危险因素,而前列腺癌病因学中遗传因素的贡献很高。最近,来自瑞典的研究人员进行了一项研究,调查了兄弟间非低风险前列腺癌的一致性如何受遗传关系的影响。
研究人员在瑞典前列腺癌数据库里确定了4,262对患有前列腺癌的兄弟。他们的癌症分为低风险(Gleason评分≤6;临床分期T1-2,Nx / N0,Mx / M0;前列腺特异性抗原≤10ng/ mL)或非低风险。对于非低风险癌症的一致性的风险比(OR)通过对不同类型的兄弟(单卵双胞胎,双卵双胞胎,全兄弟,和半兄弟)的逻辑回归来计算。
在被诊断患有前列腺癌的单卵双胞胎中,在调整了诊断年龄和年份后,两个兄弟都处于非低风险类别的OR为3.82(95%CI,0.99至16.72)。在全兄弟中,相应的调整OR为1.21(95%CI,1.04至1.39)。当分析仅限于四年内被诊断出的兄弟时,结果是相似的。
非低风险前列腺癌具有遗传模式,提示其具有共有遗传因素,单卵双胞胎中一致性最高。该研究结果表明,如果一名男子的兄弟被诊断出患有非低风险的前列腺癌,他自己在临床上患前列腺癌的风险增加。

2018年4月,美国国家综合癌症网络(NCCN)发布了前列腺癌早期检测指南2018年第2版,指南主要内容包括 指南更新摘要 简介 基线评估,风险评估和早期检测评估 活组织检查适应症 活组织检查结果的管理

Clin Cancer Res: 醋酸阿比特龙治疗的前列腺癌患者中游离DNA修饰动态研究

对醋酸阿比特龙(AA)的原发性抗性能够在20%-40%的患者中发生,醋酸阿比特龙是治疗转移性去势难治性前列腺癌的关键的治疗药物。最近,有研究人员鉴定了能够对AA治疗响应进行预测的生物标记和阐释了治疗抗性相关的机制。研究人员对来自33名AA治疗患者的108份血浆样本进行了游离循环DNA(cfDNA)修饰情况分析。研究发现,在AA敏感和AA抗性患者相比中,有30个胞嘧啶表现出了显著的修饰差异(FDR

2018 GETUG建议:中度前列腺癌大分割放疗的剂量限制

2018年4月,法国泌尿生殖小组(GETUG)发布了中度前列腺癌大分割放疗的剂量限制建议,鉴于近期Ⅲ期试验结果,中度前列腺癌大分割放疗可作为低中风险前列腺癌的标准治疗方法,本文主要诊断中度前列腺癌大分割放疗的日常应用实践提供指导建议,考虑适应证,剂量,分级法,治疗前计划,剂量限制等。

Clin Transl Oncol:microRNA-4319的重新表达能够抑制前列腺癌的生长

Her-2是一种表皮生长因子受体,并在一些前列腺癌(PC)中表达,且与肿瘤的外生长相关。一些microRNA的异常调节参与了PC发病机理的调控,然而miR-4319在PC中的角色仍旧未知。最近,有研究人员对miR-4319在PC中的作用进行了研究。研究人员通过RT-qPCR对miR-4319在PC组织中的水平进行了检测,并利用Kaplan-Meier分析调查了其表达水平与患者生存之间的相关性,并利

Pathol Oncol Res:miR-146a, miR-196a2和miR-125a遗传多样性和与前列腺癌相关性研究

在印度人口中前列腺癌发生率的增加促使了易感人群和诊断所用的遗传标记的鉴定。之前的研究表明microRNA在致瘤过程中具有重要的作用,具体是通过改变增殖、分化和细胞死亡来发挥作用。基因的多样性,包括启动子区域和miRNA基因区域的多样性,都能够影响基因的表达。最近,有研究人员分析了miR-146a, miR-196a2和miR-125a在前列腺癌患者中的多样性情况。研究发现,在100个案例和100个

Cancer Epidemiol:PSA,不止“前列腺特异”那么简单

作为FDA批准的首个肿瘤标志物,前列腺特异性抗原(prostate-specific antigen,PSA)早已成为前列腺癌诊断及筛查的重要指标。最初认为PSA仅由前列腺产生,但目前有研究表明该抗原可表达于多种非前列腺组织,女性中出现该抗原的高表达可能与某些类型的癌有关,如乳腺癌等。最近,墨西哥新莱昂州自治大学Pérez-Ibave等人在《Cancer Epidemiology》发表综述,介绍了
