人附睾蛋白4在卵巢癌中的研究进展

卵巢癌是严重威胁女性健康的恶性疾病之一。糖类抗原125（carbohydrate antigen125,CA125）是目前临床上广泛用于诊断卵巢上皮性癌的肿瘤标记物,然而其缺乏敏感性和特异性,因此,迫切需要寻找一种新的标志物来提高卵巢癌的诊断。人附睾蛋白4（human epididymis protein4,HE4）是近年发现的肿瘤标志物,其在良性肿瘤和正常组织中含量极低,但在卵巢癌中高表达。本文就HE4在卵巢癌中的诊断,动态监测等方面的进展做一综述。

Evaluation of proteomics-identified CCL18 and CXCL1 as circulating tumor markers for differential diagnosis between ovarian carcinomas and benign pelvic masses

A lack of sensitive and specific tumor markers for early diagnosis and treatment is a major cause for the high mortality rate of ovarian cancer. The purpose of this study was to identify potential proteomics-based biomarkers useful for the differential diagnosis between ovarian cancer and benign pelvic masses. Serum samples from 41 patients with ovarian cancer, 32 patients with benign pelvic masses, and 41 healthy female blood donors were examined, and proteomic profiling of the samples was assessed by surface-enhanced laser desorption/ionization time-of-flight (SELDI-TOF) mass spectroscopy (MS). A confirmatory study was also conducted with serum specimens from 58 patients with ovarian carcinoma, 37 patients with benign pelvic masses, and 48 healthy women. A classification tree was established using Biomarker Pattern Software. Six differentially expressed proteins (APP, CA 125, CCL18, CXCL1, IL-8, and ITIH4) were separated by high-performance liquid chromatography and identified by matrix-assisted laser desorption/ionization (MALDI)-MS/MS and database searches. Two of the proteins overexpressed in ovarian cancer patients, chemokine CC2 motif ligand 18 (CCL18) and chemokine CXC motif ligand 1 (CXCL1), were automatically selected in a multivariate predictive model. These two protein biomarkers were then validated and evaluated by enzyme-linked immunosorbent assay (ELISA) in 535 serum specimens (130 ovarian cancer, 64 benign ovarian masses, 36 lung cancer, 60 gastric cancer, 55 nasopharyngeal carcinoma, 48 hepatocellular carcinoma, and 142 healthy women). The combined use of CCL18 and CXCL1 as biomarkers for ovarian cancer had a sensitivity of 92% and a specificity of 97%. The multivariate ELISA analysis of the two putative markers in combination with CA 125 resulted in a sensitivity of 99% for healthy women and 94% for benign pelvic masses, and a specificity of 92% for both groups; these values were significantly higher than those obtained with CA 125 alone (p and lt;0.05). We conclude that serum CCL18 and CXCL1 are potentially useful as novel circulating tumor markers for the differential diagnosis between ovarian cancer and benign ovarian masses.     

Development of multiplexed bead-based immunoassays for the detection of early stage ovarian cancer using a combination of serum biomarkers

CA125 as a biomarker of ovarian cancer is ineffective for the general population. The aim of this study was to evaluate multiplexed bead-based immunoassay of multiple ovarian cancer-associated biomarkers such as transthyretin and apolipoprotein A1, together with CA125, to improve the identification and evaluation of prognosis of ovarian cancer. We measured the serum levels of CA125, transthyretin, and apolipoprotein A1 from the serum of 61 healthy individuals, 84 patients with benign ovarian disease, and 118 patients with ovarian cancer using a multiplex liquid assay system, Luminex 100. The results were then analyzed according to healthy and/or benign versus ovarian cancer subjects. When CA125 was combined with the other biomarkers, the overall sensitivity and specificity were significantly improved in the ROC curve, which showed 95% and 97% sensitivity and specificity, respectively. At 95% specificity for all stages the sensitivity increased to 95.5% compared to 67% for CA125 alone. For stage I+II, the sensitivity increased from 30% for CA125 alone to 93.9%. For stage III+IV, the corresponding values were 96.5% and 91.6%, respectively. Also, the three biomarkers were sufficient for maximum separation between noncancer (healthy plus benign group) and stage I+II or all stages (I-IV) of disease. The new combination of transthyretin, and apolipoprotein A1 with CA125 improved both the sensitivity and the specificity of ovarian cancer diagnosis compared with those of individual biomarkers. These findings suggest the benefit of the combination of these markers for the diagnosis of ovarian cancer.

Tumor antigen NB/70K and CA 125 levels in the blood of preoperative ovarian cancer patients and controls: a preliminary report of the use of the NB12123 and CA 125 radioimmunoassays alone and in combination

The NB12123 and CA125 radioimmunoassays, murine monoclonal antibody assays for measuring circulating levels of human ovarian tumor associated antigens NB/70K and CA 125, respectively, have been previously described. In the present study, preoperative serum samples were obtained from patients undergoing laparotomy for benign neoplastic ovarian tumors (N = 16), cancer of the cervix (N = 22), cancer of the uterus (N = 20), and cancer of the ovary (N = 47). Controls (N = 50) were obtained from healthy blood bank donors. No correlation was observed between the levels of NB/70K and CA 125 in these samples (r2 = .079, linear regression analysis). In general, increasing levels of both antigens were present with increasing tumor burden and higher histological grade. In addition, both markers were most elevated in the serum of ovarian cancer patients with serous and unclassified adenocarcinomas. Using 40 AU and 35 unit cut-offs for the NB/70K and CA 125 assay, respectively, overall specificity for healthy controls and patients with benign diseases approaches 100%. The combined sensitivity of the assays for ovarian cancer patient sera in this study indicates that the assays may be helpful in establishing a pre operative diagnosis of ovarian cancer. Complementarity of the NB/70K and CA 125 assays has been demonstrated, indicating that one or both assays may be used to monitor as many as 85% of ovarian cancer patients.
