【Abstract】Objective:To explore the relationship between microRNA-296-5p(miR-296-5p),S-phase kinase-associated protein 2(Skp2),ribosomal protein L6 (RPL6) and pathological characteristics of prostate cancer,as well as their impact on surgical prognosis. Methods:A total of 120 patients with prostate cancer who were treated from January 2018 to January 2023 were enrolled,and all pa? tients underwent laparoscopic therapy for prostate cancer. The mRNA expression levels of miR-296-5p,Skp2,and RPL6 were com? pared between the patients with different pathological features,and the association between each indicator and pathological features was analyzed. According to the presence or absence of recurrence at 1 year after surgery,the patients were divided into recurrence group with 21 patients and non-recurrence group with 97 patients. The two groups were compared in terms of clinical data and the mRNA expression levels of miR-296-5p,Skp2,and RPL6,and the influ? ence of miR-296-5p,Skp2,and RPL6 on surgical prognosis and their predictive value were analyzed. Results:There were statisti?cally significant differences in the expression levels of miR-296-5p,Skp2,and RPL6 mRNA among patients with different pathologi? cal stages,Gleason scores,preoperative serum prostate specific antigen(PSA) levels,and lymph node metastasis(F=12.927,22.416,10.088,34.239,20.180,12.208;t=4.649,-5.770,-5.713,4.716,-5.647,-6.884;P=0.000 for all). miR-296-5p was negatively corre? lated with Gleason score,pathological stage,preoperative serum PSA level,and lymph node metastasis(r=-0.578,-0.539,-0.517,-0.556;P<0.001 for all),while Skp2 and RPL6 mRNA were positively correlated with Gleason score,pathological stage,preoperative serum PSA level,and lymph node metastasis(r=0.531,0.507,0.476,0.493,0.494,0.473,0.420,0.505;P<0.001 for all). Compared with the non-recurrence group,the recurrence group had significantly higher lymph node metastasis,pathological stage,rate of positive margin,and Gleason score and a significantly lower rate of postoperative adjuvant therapy(P<0.05). Compared with the nonrecurrence group,the recurrence group had a significantly higher expression level of miR-296-5p and significantly lower mRNA ex? pression levels of Skp2 and RPL6(P<0.05). Before correction,the logistic regression analysis showed that pathological stage,Gleason score,lymph node metastasis,positive surgical margin,postoperative adjuvant therapy,and the mRNA expression levels of miR-296-5p,Skp2,and RPL6 mRNA were influencing factors for postoperative biochemical recurrence in patients with prostate cancer(P< 0.05),and after correction,the mRNA expression levels of miR-296-5p,Skp2,and RPL6 were still influencing factors for postopera? tive biochemical recurrence in patients with prostate cancer (P<0.05). The ROC curve analysis showed that the combination of miR-296-5p,Skp2,and RPL6 had an area under the ROC curve of 0.902(95%CI=0.833~0.949) in predicting biochemical recurrence af? ter prostate cancer surgery,with a significantly larger AUC than each indicator alone(P<0.05). Conclusion:The expression levels of miR-296-5p,Skp2,and RPL6 are closely associated with pathological features and postoperative recurrence in patients with prostate cancer,and the combination of the three indicators has a high reference value in predicting biochemical recurrence after prostate can? cer surgery.

国际癌症数据显示,2020年全球前列腺癌新发病例为141.4万,占全部男性癌症14.10%,是全球男性第二位恶性肿瘤,其死亡率在男性癌症中位居第五位[1]。腹腔镜前列腺癌根治术是治疗前列腺癌有效途径之一,能延长患者生存期,但由于恶性肿瘤生物学特性、细胞残留及远处微转移等原因,术后生化复发较为严重,影响预后[2]。微小RNA(mi? croRNA,miRNA)属于非编码RNA,在肿瘤发生发展过程发挥抑癌或原癌基因作用,有证据显示,miRNA与前列腺癌进展有关[3]。如Lee KH等[4]研究发现,miR-296-5p在前列腺组织和细胞中低表达,过表达miR-296-5p能明显抑制前列腺癌细胞增殖和克隆形成能力。S期激酶相关蛋白2(S-phase kinase-associated protein 2,Skp2)是F盒蛋白家族成员,在细胞周期、转移及侵袭中扮演着重要角色,段松等[5]研究发现,Skp2在前列腺癌组织高表达,与术后复发及临床病理特征有关。核糖体蛋白L6(ribo? somal protein L6,RPL6)是核糖体大亚基因之一,在多种实体瘤中异常表达,如RPL6在前列腺癌中高表达,与细胞损伤、细胞增殖及侵袭等有关[6]。但临床关于miR-296-5p、RPL6、Skp2联合在前列腺癌中的研究鲜见。基于此,本研究主要探究miR-296- 5p、Skp2、RPL6与前列腺癌病理特征的关系,并分析三者联合对患者术后的预测价值,以期为临床个性化治疗提供参考。

3 讨 论

前列腺癌发病原因尚未阐述清楚,可能与年龄、雄性激素、高脂肪饮食及遗传等因素有关,上述因素均可影响前列腺癌发生发展[10]。腹腔镜前列腺癌根治术是治疗前列腺癌的主要途径,能延长患者生存期,但术后27%~53%患者可能会出现生化复发[11]。本研究中,术后1年内生化复发率为17.50%明显低于魏英等[12]的报道,可能与术后随访时间、纳入样本量不同有关。相关研究报道显示,前列腺癌不良预后与临床病理特征有直接关联性,可见早期诊断前列腺癌对改善患者预后、延长生存期具有重要作用。

miRNA是内源性非编码RNA转录本,通过调节靶基因转录后水平参与肿瘤细胞生物学进展[13]。miR-296是miRNA家族成员,涉及miR-296-5p、miR-296-3p,miRase在线数据库显示,miR-296是miR-296-5p之前名字,主要位于20q13.32区域,最近癌症数据显示,miR-296-5p在多种恶性肿瘤中异常表达,表现出明显异质性,通过作用不同靶基因,呈现不同抑癌或促癌作用[14]。但关于miR-296-5p在前列腺癌血清及与临床病理特征的研究未见报道。本研究结果显示,不同病理分期、术前PSA水平、Gleason评分、淋巴结转移患者miR-296-5p存在明显差异,复发组miR-296-5p表达水平低于未复发组,提示miR-296-5p与临床病理特征、术后复发密切相关。PSA是早期诊断和监测前列腺癌常用指标,正常情况下PSA几乎不表达,若前列腺发生癌变后引起血-上皮细胞屏障破坏,导致PSA进入血液中,血清PSA浓度与恶性肿瘤呈相关[15]。Glea? son评分≥7分提示前列腺癌处于低分化或未分化,为高级别癌,患者术后复发或转移风险较高[16]。miR-296-5p不仅参与肿瘤血管生成、细胞迁移和侵袭、细胞增殖,还能调节肿瘤干细胞表现、诱导细胞凋亡等[14]。于峰等[17]研究发现,miR-296-5p在前列腺癌细胞中低表达,沉默Circ-0033074可能通过上调miR-296-5p抑制前列腺癌细胞增殖、迁移和侵袭,并诱导细胞凋亡,提示miR-296-5p有望成为前列腺癌作用靶点,但具体作用机制尚不清楚,有待下一步考究。

Skp2是一种与细胞周期有关的蛋白,与DNA复制有关,主要位于5p13区域,首次在1995年呈现细胞S期中发现,可与细胞周期蛋白CyclinA相互作用,从而参与细胞增殖分化、周期进展[18]。既往研究显示,Skp2在胃癌、前列腺癌等组织中高表达,沉默Skp2能明显抑制肿瘤细胞增殖和细胞进展,并诱导晚期细胞凋亡[19-20]。本研究结果显示,Skp2与病理分期、Gleason评分、术前血清PSA水平、淋巴结转移呈正相关,复发患者Skp2高于未复发组,这与段松等[5]的研究结果相同,提示Skp2与前列腺癌病理特征和术后复发有关。Skp2水平升高能阻滞细胞周期进展,导致G1/S期比例升高,加剧肿瘤细胞增殖分化,加快前列腺癌发展[21]。Skp2丝氨酸和巯基结构也能促进肿瘤细胞持续复制,加快肿瘤细胞增殖分化[22]。相关研究认为,Skp2表达越高,主要是因为PSA水平越高,肿瘤恶性程度严重,肿瘤细胞增殖速度较快,Skp2合成和释放越明显[23]。

RPL6是核糖体蛋白主要成分,近年证据显示,核糖体蛋白除了参与核糖体组成外,还能参与细胞增殖分化、DNA复制和转录、凋亡及迁移等过程[24]。RPL6主要位于12q24.1区域,有研究表明,RPL6在前列腺癌组织中高表达,与病理分期、术后生化复发密切相关[6]。本研究结果显示,RPL6与病理分期、Gleason评分、术前血清PSA水平、淋巴结转移呈正相关,复发组RPL6 mRNA表达水平高于未复发组,这与上述研究观点一致,提示RPL6与前列腺癌发生发展密切相关。Zhang J等[25]研究发现,下调RPL6能抑制肿瘤细胞增殖和转移,并诱导细胞凋亡。本研究进一步分析发现,miR-296-5p、Skp2、RPL6联合预测前列腺术后生化复发的AUC大于各指标单独预测,提示三者联合预测患者术后生化复发具有良好参考价值。

综上所述,前列腺癌患者miR-296-5p、Skp2、RPL6表达水平与病理特征、术后复发存在一定关系,miR-296-5p、Skp2、RPL6可用于前列腺术后生化复发预测,三者联合预测价值更高,可用作前列腺癌术后复发评估的指标,为前列腺癌术后评估提供参考依据,有助于临床医师早期制定合理干预措施。但本研究存在不足,本研究仅随访1年,下一步动态监测血清指标表达,延长随访期限,观察其对术后复发患者的预测价值。
