目的

探讨甘油三酯-葡萄糖(TyG)指数与术后肾细胞癌患者预后的相关性。

方法

回顾性分析2019年1月至2022年1月淮安市第二人民医院接受手术治疗的108例肾细胞癌患者临床资料,采用Kaplan-Meier法及Cox比例风险回归模型对患者的预后进行分析。计算TyG指数,通过随访获取患者的预后信息,采用Pearson相关分析TyG指数与患者预后指标(总生存期)的关系。

结果

不同TyG指数水平患者空腹血糖(FBG)、甘油三酯(TG)、胰岛素水平(INS)、肌酐(Cr)等差异均具有统计学意义(P<0.05)。术后随访49(35,60)个月,108例肾细胞癌术后患者死亡28例(25.93%),存活80例(74.07%),中位生存时间(OS)48(34,60)个月,低TyG组死亡6例(11.76%),存活45例(88.24%),中位OS 45(33,58)个月,中TyG组死亡10例(25.64%),存活29例(74.36%),中位OS 40(30,56)个月,高TyG组死亡12例(66.67%),存活6例(33.33%),中位OS 37(28,55)个月,三组OS差异有统计学意义(P<0.05)。Cox回归分析显示,高FBG、TG、INS、HOMA-IR、Cr均为肾细胞癌患者术后预后的危险因素(P<0.05)。Pearson相关分析结果显示,TyG指数与FBG、TG、INS、HOMA-IR、Cr等指标呈正相关(r=0.825、0.932、0.841、0.585、0.855),且相关性显著(P<0.05)。

结论

TyG指数与肾细胞癌患者术后预后密切相关,高TyG指数患者术后预后更差。

Objective

To investigate the correlation between triglyceride glucose (TyG) index and the prognosis of postoperative renal cell carcinoma patients.

Methods

A retrospective analysis was conducted on the clinical data of 108 patients with renal cell carcinoma who underwent surgical treatment at the Second People's Hospital of Huai'an City from January 2019 to January 2022. Kaplan-Meier method and Cox proportional hazards regression model were used to analyze the prognosis of the patients. Calculate the TyG index, obtain patient prognosis information through follow-up, and use Pearson correlation analysis to examine the relationship between TyG index and overall survival(OS) of patients.

Results

The differences in fasting blood glucose (FBG), triglycerides (TG), insulin levels (INS), creatinine (Cr), and other parameters among patients with different TyG index levels were statistically significant (P<0.05). After a follow-up of 49(35, 60) months postoperatively, 28 out of 108 patients with renal cell carcinoma died (25.93%), survived (74.07%), and had a median OS of 48 (34, 60) months. The low TyG group died in 6 cases (11.76%), survived in 45 cases (88.24%), had a median OS of 45 (33, 58) months, the medium TyG group died in 10 cases (25.64%), survived in 29 cases (74.36%), had a median OS of 40 (30, 56) months, the high TyG group died in 12 cases (66.67%), survived in 6 cases (33.33%), and had a median OS of 37 (28, 55) months. The difference in group OS was statistically significant (P<0.05). Cox regression analysis showed that high FBG, TG, INS, HOMA-IR, and Cr were all risk factors for postoperative prognosis in patients with renal cell carcinoma (P<0.05). The Pearson correlation analysis results showed that the TyG index was positively correlated with FBG, TG, INS, HOMA-IR, Cr and other indicators (r=0.825, 0.932, 0.841, 0.585, 0.855), and the correlation was significant (P<0.05).

Conclusion

The TyG index is closely related to the postoperative prognosis of patients with renal cell carcinoma, and patients with high TyG index have worse postoperative prognosis.
