The clinical treatment of ovarian cancer with ascites is problematic. The main reasons for treatment failure are the susceptibility to intraperitoneal metastasis and chemotherapeutic drug resistance. The purpose and significance of this study is to evaluate which marker might evaluate treatment efficacy and improve the cure rate.
This study compared a no chemotherapy group with a chemotherapy group regarding the determination of carbohydrate antigen 125 and human epididymis protein 4 in ovarian cancer ascitic supernatants and cross-analyzed routine serum carbohydrate antigen 125 levels. The level of human epididymis protein 4 in the ascites of the chemotherapy group was significantly lower than that of the no chemotherapy group (p < 0.001). Moreover, the expression of ascitic human epididymis protein 4 correlated positively with serum carbohydrate antigen 125 levels (p < 0.001). MDR was positive in 13 of the 30 samples (43.33%) in the chemotherapy group with highly expressed CA125.
The level of human epididymis protein 4 in ovarian cancer ascites may reflect the therapeutic effect of ovarian cancer patients, and a high level of human epididymis protein 4 might predict chemoresistance and the possibility of ascites formation. The determination of the expression of human epididymis protein 4 alone or combined with carbohydrate antigen 125 levels in both serum and ascites in ovarian cancer patients with ascites may have important significance for guiding and improving the treatment regimen.
卵巢癌合并腹水的临床治疗存在问题。治疗失败的主要原因是易发生腹腔内转移和化疗药物耐药。本研究的目的和意义在于评估哪种标志物可能评估治疗效果,提高治愈率。
本研究比较了卵巢癌腹水上清液中糖链抗原 125 和人附睾蛋白 4 的测定值,对无化疗组和化疗组进行了分析,并对常规血清糖链抗原 125 水平进行了交叉分析。化疗组的人附睾蛋白 4 水平明显低于无化疗组(p<0.001)。此外,腹水人附睾蛋白 4 的表达与血清糖链抗原 125 水平呈正相关(p<0.001)。在化疗组的 30 个样本中(43.33%),有 13 个样本 MDR 呈阳性,CA125 高表达。
卵巢癌腹水中人附睾蛋白 4 的水平可能反映卵巢癌患者的治疗效果,高水平的人附睾蛋白 4可能预测化疗耐药和腹水形成的可能性。单独或联合检测血清和腹水中人附睾蛋白 4 的表达水平,对指导和改善卵巢癌腹水患者的治疗方案可能具有重要意义。
