Prostate cancer P D:年龄不大于50岁男性中前列腺癌肿瘤特性、治疗和肿瘤治疗结果研究

2018-01-30 AlexYang MedSci原创

最近,有研究人员调查了年龄不大于50岁 vs. 年龄大于50岁男性中,前列腺癌(PCa)的临床特性、治疗方法和肿瘤治疗结果。在407599名患有前列腺原发性腺癌的男性中,18387名男性年龄不大于50岁(4.5%)。研究人员在年轻病人和年老病人之间测试了时间趋势、累积发病率和竞争风险回归(CRR)之间的差异,并利用多变量分析调整了诊断年限、种族、婚姻状况、格林森得分、临床肿瘤阶段和淋巴结状态。研究

最近,有研究人员调查了年龄不大于50岁 vs. 年龄大于50岁男性中,前列腺癌(PCa)的临床特性、治疗方法和肿瘤治疗结果。在407599名患有前列腺原发性腺癌的男性中,18387名男性年龄不大于50岁(4.5%)。研究人员在年轻病人和年老病人之间测试了时间趋势、累积发病率和竞争风险回归(CRR)之间的差异,并利用多变量分析调整了诊断年限、种族、婚姻状况、格林森得分、临床肿瘤阶段和淋巴结状态。

研究发现,与年老的男性对比,年轻男性具有更为有利的肿瘤特性:更低的格林森得分、更低的中值PSA以及更低的转移发生率。随着时间的推移,非局部治疗(NLT)比例增加,根治性前列腺癌切除(RP)和短距离放射治疗(BT)比例减少,并且外照射(EBRT)比例保持不变。更多的是,新发生的转移性前列腺癌比例在年轻病人中从2%(2004)增加到了3.2%(2013)(p=0.004)。CRR模型表明了在前列腺特异性死亡率(PCSM)上,年轻男性和年老男性之间没有差异,并且涵盖了所有局部治疗类型。

最后,研究人员指出,目前,年轻PCa病人具有更多的有利的疾病特性,他们很少使用RP或者BT治疗,并且更可能从NLT中受益。另外,在年轻和年老病人之间,PCSM没有有差异。然而,令人担忧的是,更多的PCa年轻病人诊断为在转移阶段。
