摘要:

目的 探讨血清铁调素抗菌肽(HAMP)、分泌型磷蛋白1(SPP1)、G蛋白信号转导调节因子2(RGS2)水平与胃癌患者临床病理特征的相关性及对术后复发或转移的预测价值。方法 选取2021年3月至2023年3月在邯郸市第一医院治疗的92例胃癌患者作为胃癌组,另选取同期健康体检人群92例作为对照组,比较两组血清HAMP、SPP1、RGS2水平。根据胃癌患者血清中HAMP、SPP1、RGS2水平的均值,将患者分为HAMP高水平组、HAMP低水平组,SPP1高水平组、SPP1低水平组,RGS2高水平组、RGS2低水平组,并分别比较不同HAMP、SPP1、RGS2水平胃癌患者的临床病理特征。术后中位随访18个月,根据肿瘤是否复发或转移将胃癌患者分为未复发转移组(n=59例)、复发转移组(n=33例),比较两组患者血清HAMP、SPP1、RGS2水平。采用受试者操作特征(ROC)曲线分析HAMP、SPP1、RGS2对胃癌患者术后复发或转移的预测价值。结果 与对照组相比,胃癌组血清HAMP[(52.28±5.44)ng/ml比(31.22±4.18)ng/ml]、SPP1[(55.96±6.43)ng/ml比(36.99±5.25)ng/ml]水平均较高(t=29.44,P<0.001;t=21.92,P<0.001),RGS2[(3.72±0.66)mg/L比(5.11±0.87)mg/L)]水平较低(t=12.21,P<0.001)。HAMP高水平组(n=44)与HAMP低水平组(n=48)、SPP1高水平组(n=43)与SPP1低水平组(n=49)、RGS2高水平组(n=50)与RGS2低水平组(n=42)胃癌患者在肿瘤最大径(χ2=13.07,P<0.001;χ2=6.71,P=0.010;χ2=10.56,P=0.001)、TNM分期(χ2=7.42,P=0.006;χ2=6.36,P=0.012;χ2=5.39,P=0.020)、淋巴结转移(χ2=23.41,P<0.001;χ2=6.52,P=0.011;χ2=13.11,P<0.001)、分化程度(χ2=9.01,P=0.003;χ2=7.97,P=0.005;χ2=15.29,P<0.001)方面的差异均有统计学意义。与未复发转移组相比,复发转移组血清HAMP[(59.26±5.66)ng/ml比(48.37±4.28) ng/ml]、SPP1[(62.85±6.36)ng/ml比(52.11±5.38)ng/ml]水平较高(t=10.40,P<0.001;t=8.60,P<0.001),RGS2[(3.01±0.48)mg/L比(4.12±0.69)mg/L]水平较低(t=8.19,P<0.001)。ROC曲线分析显示,血清HAMP、SPP1、RGS2水平单独预测胃癌患者术后复发或转移的曲线下面积(AUC)值分别为0.777、0.813、0.778,三者联合预测胃癌患者术后复发或转移的AUC值为0.871,三指标联合预测胃癌患者术后复发或转移的预测效能优于单独预测(Z=2.51,P=0.035;Z=2.61,P=0.032;Z=2.71,P=0.029)。结论 胃癌患者血清中HAMP、SPP1水平升高,RGS2水平降低,三者水平与肿瘤最大径、TNM分期、淋巴结转移、分化程度有关,且三者联合检测对于胃癌患者术后复发或转移预测价值较高。

Abstract:

Objective To explore the correlation between serum hepcidin antimicrobial peptide (HAMP), secreted phosphoprotein 1 (SPP1), and regulator of G protein signaling 2 (RGS2) levels and the clinical pathological characteristics of gastric cancer patients, and their predictive value for postoperative recurrence or metastasis. Methods A total of 92 gastric cancer patients treated at Handan First Hospital from March 2021 to March 2023 were selected as the gastric cancer group, and 92 healthy individuals who underwent physical examinations during the same period were selected as the control group. The serum levels of HAMP, SPP1 and RGS2 were compared between the two groups. According to the mean levels of HAMP, SPP1, and RGS2 in the serum of gastric cancer patients, they were divided into HAMP high level group and HAMP low level group, SPP1 high level group and SPP1 low level group, RGS2 high level group and RGS2 low level group. The clinicopathological characteristics of gastric cancer patients with different levels of HAMP, SPP1 and RGS2 were compared respectively. After a median follow-up of 18 months, gastric cancer patients were divided into a non-recurrence or metastasis group (n=59) and a recurrence and metastasis group (n=33) based on whether the tumor recurred or metastasized. The serum levels of HAMP, SPP1, and RGS2 were compared between the two groups of patients. The predictive value of HAMP, SPP1 and RGS2 for postoperative recurrence or metastasis in patients with gastric cancer was analyzed by using the receiver operator characteristic (ROC) curve. Results Compared with the control group, the gastric cancer group had higher levels of serum HAMP [(52.28±5.44) ng/ml vs. (31.22±4.18) ng/ml] and SPP1 [(55.96±6.43) ng/ml vs. (36.99±5.25) ng/ml] (t=29.44, P<0.001; t=21.92, P<0.001), and lower level of RGS2 [(3.72±0.66) mg/L vs. (5.11±0.87) mg/L)] (t=12.21, P<0.001). There were statistically significant differences in maximum tumor diameter (χ2=13.07, P<0.001; χ2=6.71, P=0.010; χ2=10.56, P=0.001), TNM staging (χ2=7.42, P=0.006; χ2=6.36, P=0.012; χ2=5.39, P=0.020), lymph node metastasis (χ2=23.41, P<0.001; χ2=6.52, P=0.011; χ2=13.11, P<0.001), and differentiation degree (χ2=9.01, P=0.003; χ2=7.97, P=0.005; χ2=15.29, P<0.001) between the gastric cancer patients in the HAMP high level group (n=44) and the HAMP low level group (n=48), the SPP1 high level group (n=43) and the SPP1 low level group (n=49), and the RGS2 high level group (n=50) and the RGS2 low level group (n=42). Compared with the non-recurrence or metastatic group, the recurrence and metastatic group had higher levels of serum HAMP [(59.26±5.66) ng/ml vs. (48.37±4.28) ng/ml] and SPP1 [(62.85±6.36) ng/ml vs. (52.11±5.38) ng/ml] level (t=10.40, P<0.001; t=8.60, P<0.001), and lower level of RGS2 [(3.01±0.48) mg/L vs. (4.12±0.69) mg/L] (t=8.19, P<0.001). ROC curve analysis showed that the area under the curve (AUC) values of serum HAMP, SPP1, and RGS2 levels alone for predicting postoperative recurrence or metastasis in gastric cancer patients were 0.777, 0.813, and 0.778, respectively. The AUC value of the combination of the three indicators for predicting postoperative recurrence or metastasis in gastric cancer patients was 0.871. The predictive efficacy of the combination of the three indicators for predicting postoperative recurrence or metastasis in gastric cancer patients was better than that alone (Z=2.51, P=0.035; Z=2.61, P=0.032; Z=2.71, P=0.029). Conclusions The levels of HAMP and SPP1 in the serum of gastric cancer patients increase, while the level of RGS2 decreases, and the levels of the three are related to the maximum tumor diameter, TNM staging, lymph node metastasis and differentiation degree, and their combined detection has higher predictive value for postoperative recurrence or metastasis in gastric cancer patients.
