【摘要】目的:探讨基于长链非编码 RNA(lncRNA)PTENP1、血清纤维蛋白降解复合物(DR-70)在早期胃癌诊断及胃癌进展中的效能评估研究。方法:本研究选取了2020年4月至2021年2月佛山市第五人民医院收治的胃癌患者100例为观察组,并选择同期进行胃镜检查者50例为胃良性病变组和健康体检者50例为正常组,采用 PCR 检测血清 lncRNA PTENP1的表达水平,采用肿瘤标记 DR-70酶免疫分析早期胃癌的检测水平。结果:胃良性病变组与健康组的血清 lncRNA PTENP1 水平(54.67±3.81)-log、(58.03±3.69)-log 高于胃癌组患者的水平(10.58±1.69)-log,差异具有统计学意义(F =13.132, P =0.001);胃癌组患者的 DR-70水平(4.51±0.58)μg/mL 高于胃良性病变组与健康组的 DR-70水平(0.71±0.45)μg/ mL、(0.43±0.36)μg/ mL,差异具有统计学意义(F =7.621, P =0.003);患者的血清 DR-70与患者的 TNM 分期/淋巴转移呈现相关性(r =-6.583, P =0.037; r =-6.146, P =0.005)。胃癌患者血清 lncRNA PTENP1联合 DR-70检测敏感性与特异性显著提高。结论:血清 lncRNAPTENP1、DR-70联合检测在早期胃癌诊断中具有较好的应用价值。

【Abstract】Objective:To evaluate the e?cacy of serum lncRNA PTENP1,DR-70 in the diagnosis of early gastric cancer and gastric cancer progression.Methods:This study selected 100 patients with gastric cancer treated from April 2020 to February 2021.At the same period,50 patients with gastroscopy in this hospital were patients with benign gastric lesions and 50 patients were normal groups.The expression level of serum lncRNA PTENP1 was measured by PCR,and the detection level of early tumor cancer was used.Results:Serum lncRNA PTENP1 levels in benign and healthy groups [(54.67±3.81)-log,(58.03±3.69)-log]higher than those in the gastric cancer group(10.58±1.69)-log,The di?erences are statistically signi?cant(F=13.132,P=0.001);DR-70 levels in patients[(4.51±0.58)μg/ mLin the gastric cancer group]were higher than in benign and healthy patients[(0.71±0.45)μg/ mL,(0.43±0.36)μg/ mL],Di?erences have statistical signi?cance;Serum DR-70 was associated with TNM staging and lymphatic metastasis(r=-6.583,P=0.037;r=-6.146,P=0.005).Serum lncRNA PTENP1 and DR-70 detection sensitivity and speci?city were signi?cantly improved in patients with gastric cancer.Conclusion:Serum lncRNA PTENP1,DR-70 combination test is useful in early diagnosis of gastric cancer.

胃癌是我国最常见的恶性肿瘤之一,研究发现胃癌的死亡率较高,严重影响了患者的预后治疗[1-3]。近年来,随着胃镜检查的普及,胃癌患者的发病率呈现下降趋势。随着生活节奏的加快、饮食结构的改变,胃癌发病人群逐步呈现出低龄化倾向。由于大多数人在就诊时病情已处于胃癌中晚期,所以生存质量明显下降。因此,早期监测、早期诊断对于胃癌预后显得尤为重要。本研究探讨基于血清 lncRNA PTENP1、DR-70在早期胃癌诊断及胃癌进展中的效能评估研究。
