卵巢癌患者淋巴结转移的超声造影定量参数评估及其与疗效的关系
Evaluation of quantitative parameters of contrast-enhanced ultrasound in the patients with lymph node metastasis ovarian cancer and its relationship with treatment efficacy
目的 探究卵巢癌患者淋巴结转移的超声造影定量参数评估及其与治疗效果的关系。 方法 回顾性分析黄河三门峡医院2019年2月至2021年2月收治的137例卵巢癌患者的临床资料。依据患者是否出现淋巴结转移分为转移组(76例)与未转移组(61例),比较2组患者的超声造影定量参数,并通过受试者工作特征曲线(receiver operating characteristic curve,ROC)分析不同的超声造影定量参数对患者是否发生淋巴结转移的诊断价值;对转移组患者采取4个周期的新辅助放化疗,依据治疗结果分为有效组(55例)与无效组(21例),对比分析2个亚组患者的超声造影定量参数与临床疗效的关系。 结果 (1)转移组患者的基础强度(12.79 ± 1.93)dB低于未转移组(14.70 ± 2.51)dB、达峰时间(28.34 ± 2.86)s长于未转移组(26.98 ± 3.27)s,差异有统计学意义(P<0.05);(2)基础强度、达峰时间对卵巢癌患者淋巴结转移诊断的ROC曲线下面积(area under curve, AUC)依次为0.730、0.627,敏感度依次为90.8%、92.1%,特异度依次为47.5%、34.4%,差异有统计学意义(P<0.05);(3)有效组患者的基础强度(15.68 ± 2.57)dB高于无效组(13.27 ± 1.92)dB、达峰时间(25.76 ± 3.31)s短于无效组(27.81±2.89)s,差异有统计学意义(P<0.05);(4)基础强度与治疗效果呈显著正相关(r=0.413),达峰时间与治疗效果呈显著负相关(r=-0.279),差异有统计学意义(P<0.05)。 结论 超声造影定量参数对评估卵巢癌患者淋巴结是否转移具有较好的诊断价值,能够作为评价患者是否发生淋巴结转移的重要指标;卵巢癌患者淋巴结转移的超声造影定量参数与临床疗效具有显著的相关性,能够为评估肿瘤进展及临床治疗方案提供有效的科学依据。
Objective To explore the quantitative parameter evaluation of contrast-enhanced ultrasound in the patients with lymph node metastasis ovarian cancer and its relationship with treatment efficacy. Methods The clinical data of 137 patients with ovarian cancer admitted to the Huanghe Sanmenxia Hospital from February 2019 to February 2021 were analyzed retrospectively.The patients were divided into the metastatic group (n=76) and the non⁃metastatic group (n=61), depending on whether or not there was lymph node metastasis. Then, differences in quantitative parameters of contras⁃enhanced ultrasound were compared between the patients of the two groups, and the diagnostic value of different quantitative parameters of contrast⁃enhanced ultrasound was analyzed for the patients with lymph node metastasis by using receiver operating characteristic curve (ROC) . Following 4 cycles of neoadjuvant radiotherapy and chemotherapy, the patients in the metastatic group were divided into the effective group (n=55) and the non⁃effective group (n=21), according to treatment results. The relationship between the quantitative parameters of ultrasound contrast and the clinical efficacy in the two sub⁃groups was compared. Results (1) The basic intensity (12.79 ± 1.93) of the patients in the metastasis group was lower than that of the non⁃metastatic group (14.70 ± 2.51), and the peak time (28.34 ± 2.86) of the former was higher than that of the latter (26.98 ± 3.27) (P<0.05). (2) The area under curve (AUC) in the diagnosis of lymph node metastasis in the patients with ovarian cancer was respectively 0.730 and 0.627, the sensitivity was 90.8% and 92.1%, specificity was 47.5% and 34.4%, with statistical significance (P<0.05). (3) The basic strength of the effective group (15.68 ± 2.57) was higher than that of the non⁃effective group (13.27 ± 1.92), peak time (25.76 ± 3.31) was shorter than that of the non⁃effective group (27.81 ± 2.89), also with statistical significance (P<0.05). (4) The basic intensity and treatment effect showed a significant positively correlation (r=0.413) , while the peak time was negatively correlated with the treatment effect (r=-0.279), with statistical significance (P<0.05). Conclusion The quantitative parameters of contrast⁃enhanced ultrasound are of good diagnostic value in the assessment of lymph node metastasis in the patients with ovarian cancer, and can be used as an important indicator to evaluate whether there is metastasis in the patient. The clinical efficacy of the ovarian cancer patient with lymph node metastasis is closely correlated with the quantitative parameters of contrast⁃enhanced ultrasound, which could provide solid evidence for the assessment of tumor progression and development of clinical treatment profile.
