目的

探讨SSIGN分级联合γ-谷氨酰转肽酶(GGT)在高危非转移性肾癌术后复发的预测价值。

方法

回顾性选择2020年1月至2022年1月重庆理工大学附属中心医院收治的80例高危非转移性肾癌患者资料,所有患者术前行SSIGN分级,检测血清GGT水平,术后定期门诊复诊和电话随访,统计术后肿瘤复发情况。Kaplan-Meier生存分析不同SSIGN分级、GGT水平高危非转移性肾癌患者无复发生存率,单因素和多因素Cox回归分析影响高危非转移性肾癌患者术后复发的因素。受试者工作特征曲线(ROC)分析SSIGN分级联合GGT预测高危非转移性肾癌患者术后复发的价值。

结果

中位随访19(12~36)个月,随访期间复发18例,复发率22.50%。复发组pT2、肿瘤直径≥5 cm、Fuhrman核分级3~4级、淋巴血管浸润、肿瘤坏死比例以及血清GGT水平高于无复发组(P<0.05),两组SSIGN分级比较差异具有统计学意义(P<0.05)。不同SSIGN分级无复发生存率差异具有统计学意义(P<0.05),高水平GGT组无复发生存率低于低水平GGT组(P<0.05)。多因素Cox回归结果显示pT2、SSIGN分级高危、高GGT是高危非转移性肾癌患者术后复发的危险因素(P<0.05)。SSIGN分级、GGT预测高危非转移性肾癌患者术后复发的曲线下面积分别为0.847、0.705,SSIGN分级联合GGT预测的曲线下面积为0.955,高于单独预测(P<0.05)。

结论

高危非转移性肾癌术后复发患者术前SSIGN高危比例和血清GGT水平偏高,且与低无复发生存率有关,联合SSIGN分级和GGT有助于预测高危非转移性肾癌术后复发风险。

Objective

To investigate the predictive value of SSIGN grading combined with gamma-glutamyl transpeptidase (GGT) in postoperative recurrence of high-risk non-metastatic renal carcinoma.

Methods

Data of 80 patients with high-risk non-metastatic renal cancer admitted to the Central Hospital Affiliated to Chongqing University of Technology from January 2020 to January 2022 were retrospectively analyzed. All patients underwent SSIGN grading before surgery, serum GGT level was detected, and postoperative regular outpatient visit and telephone follow-up were conducted to analyze postoperative tumor recurrence. Kaplan-Meier survival analysis was conducted for relapse-free survival of high-risk non-metastatic renal cancer patients with different SSIGN grades and GGT levels. Univariate and multivariate Cox regression analysis was conducted for factors influencing postoperative recurrence of high-risk non-metastatic renal cancer patients. Receiver operating characteristic (ROC) curve analysis of the value of SSIGN grading combined with GGT in predicting postoperative recurrence in high-risk non-metastatic renal cancer patients.

Results

The median follow-up was 19(12-36) months. During the follow-up, 18 cases relapsed, with a recurrence rate of 22.50%. pT2, tumor diameter ≥5 cm, Fuhrman nuclear grade 3-4, lymphovascular infiltration, tumor necrosis ratio and serum GGT level in the recurrence group were higher than those in the non-recurrence group (P<0.05), and the difference in SSIGN grade between the two groups was statistically significant (P<0.05). The relapse-free survival rate of different SSIGN grades was statistically significant (P<0.05), and the relapse-free survival rate of high GGT group was lower than that of low GGT group (P<0.05). Multivariate Cox regression results showed that high risk of pT2 and SSIGN grading and high GGT were risk factors for postoperative recurrence in high-risk non-metastatic renal cancer patients (P<0.05). The area under the curve predicted by SSIGN grade and GGT for postoperative recurrence of high-risk non-metastatic renal cancer was 0.847 and 0.705, respectively, and the area under the curve predicted by combined SSIGN grade with GGT was 0.955, which was higher than that predicted by alone (P<0.05).

Conclusion

High SSIGN risk ratio and serum GGT level before operation are associated with low relapse-free survival rate in high-risk non-metastatic renal cancer patients with postoperative recurrence. Combined SSIGN grade and GGT can help to predict the risk of postoperative recurrence of high-risk non-metastatic renal cancer.
