血清和胸水中CA125在结核性和癌性胸水中的表达及临床意义

目的:探讨血清和胸水中CA125在结核性和癌性胸水中的表达及鉴别诊断意义。方法:抽选我院确诊的结核性胸水病人85例(结核组)和癌性胸水病人71例(癌症组),检测两组患者血清和胸水中CA125表达,并以胸水/血清中CA125比值10(p-CA125/s-CA12510)为临界值,观察其对癌性胸水的鉴别特异度、灵敏度及准确性。结果:癌症组胸水中CA125表达及p-CA125/s-CA125比值均显著高于结核组(P0.05);但血清中两组CA125表达比较差异无显著性(P0.05);两组胸水中,以35U/ml为临界值,两组患者阳性率92.9%(79/85)、100%(71/71)比较差异无显著性(X2=7.0718,P=0.0078)。癌症组中p-CA125/sCA125比值10的比率(84.5%VS 17.6%)明显高于结核组(X2=66.6244,P=0.0000);并以其为诊断癌性胸水的临界值,鉴别诊断特异度、灵敏度及准确性分别为82.3%、84.5%、83.3%。结论:血清和胸水中CA125表达对于鉴别结核性或者是癌性胸水的临床意义不大,但是p-CA125/s-CA125比值对于鉴别结核性和癌性胸水具有一定临床价值。     

Peritoneal fluid cytokines and the differential diagnosis of benign and malignant ovarian tumors and residual/recurrent disease examination

This study aimed to assess the potential value of peritoneal fluid cytokine examination for the differential diagnosis of ovarian tumors and for evaluating residual or recurrent disease after treatment. The cytokines that are commonly elevated in ovarian cancer, VEGF, IL-6, bFGF, IL-8 and M-CSF, and a reference ovarian tumor marker, CA 125, were measured in peritoneal fluids of 53 previously untreated patients with epithelial ovarian cancer, 18 ovarian cancer patients after surgical treatment and chemotherapy, and 17 patients with benign epithelial ovarian tumors. Non-parametric statistical analysis of data was performed. Ovarian cancer peritoneal fluids, as compared to peritoneal fluids of patients with benign ovarian tumors, contained significantly higher concentrations of IL-6, VEGF and CA 125, and significantly lower concentrations of bFGF and M-CSF, but only the levels of IL-6 and VEGF were significantly higher in peritoneal fluids of stage I and II ovarian cancer patients than of patients with benign ovarian conditions. IL-6 at the cutoff level of 400 pg/mL discriminated benign and malignant ovarian tumors with 92% sensitivity and 60% specificity, while VEGF at the cutoff of 400 pg/mL had 90% sensitivity and 80% specificity. At the cutoff level of 1200 pg/mL, IL-6 had 84% sensitivity and 87% specificity. A radical decrease in local cytokine and CA 125 levels in patients after treatment was independent of therapy outcome. IL-6 and VEGF measurements in peritoneal fluids might be useful for the differential diagnosis of malignant and benign ovarian conditions, but not for residual or recurrent disease examination.

摘要 目的：探讨上皮性卵巢癌患者电子计算机断层扫描（CT）、磁共振成像（MRI）影像学特征及与血清标志物癌胚抗原（CEA）、糖类抗原199（CA199）、糖类抗原125（CA125）水平的相关性。方法：回顾性分析2014年4月-2020年2月于我院83例诊断为上皮性卵巢癌患者的CT、MRI影像学资料,以手术病理结果作为金标准。分析患者的CT、MRI影像学特征,检测患者血清CEA、CA199、CA125水平,评价患者CT、MRI影像学特征与血清CEA、CA199、CA125水平的相关性。结果：上皮性卵巢癌肿瘤横截面最大径为14.2mm-121.7mm,平均（18.6±4.3）mm,上皮性卵巢癌以混杂密度/信号为主,形态不规则,病灶多为囊实性,可见壁结节及分隔改变,增强后可见分隔或壁结节明显强化,可伴有腹水、腹膜转移、淋巴结转移。血清CEA、CA199、CA125水平分别为（66.35±7.52）ng/mL、（183.59±22.62）U/mL、（225.27±25.34）U/mL。上皮性卵巢癌边界清晰、不清晰的血清CA199、CA125水平组间差异有统计学意义（P＜0.05）;上皮性卵巢癌形态圆形/类圆形/椭圆形、分叶状、形态不规则的血清CA199、CA125水平组间差异有统计学意义（P＜0.05）;上皮性卵巢癌患者有壁结节、腹膜转移、淋巴结转移的血清CEA、CA199、CA125水平组间差异有统计学意义（P＜0.05）;其余CT、MRI影像学表现特征组间血清CEA、CA199、CA125水平差异无统计学意义（P＞0.05）。上皮性卵巢癌边界与血清CA125水平呈正相关（P＜0.05）,上皮性卵巢癌形态与血清CA199、CA125水平呈正相关（P＜0.05）,壁结节与血清CA125水平呈正相关（P＜0.05）,腹膜转移、淋巴结转移与血清CEA、CA199、CA125水平呈正相关（P＜0.05）,其余指标之间无明显相关性（P＞0.05）。结论：上皮性卵巢癌CT、MRI影像表现具有特征性,血清CEA、CA199、CA125水平的检测有助于对早期上皮性卵巢癌的诊断以及不同病理类型的判断,CT、MRI影像学特征与血清CEA、CA199、CA125水平具有相关性,可判断疾病的进展及患者预后情况,对指导临床综合治疗及评估患者预后可提供客观依据。     

Relationship of CA 125 and CA 19.9 with lung carcinoma histological subtype: preliminary study

The aim of this work was to study the possible utility of simultaneous determination of CA 125 and CA 19.9 in patients with lung cancer. Serum levels of both markers were studied in 87 patients without metastases (Mo), 72 patients with distant metastases (MT) and 15 cases without clinical evidence of disease after primary treatment (NED). Sixty-five tumors were epidermoid, 34 were adenocarcinomas, 24 were cell undifferentiated carcinomas and 51 were small-cell carcinomas. Sera from 75 healthy subjects and 20 patients with benign lung disease were used as controls. The cut-off values used were 35 and 37 U/ml for CA 125 and CA 19.9, respectively. CA 125 and CA 19.9 serum levels were within normal limits in all control patients. In NED patients these markers were not elevated, except in one with chronic liver disease who showed elevated CA 19.9 (76 U/ml). Twenty-five percent of Mo lung cancer patients and 40.3% of MT cases had CA 19.9 over 37 U/ml. Abnormally high levels of CA 125 were found in 18.7% and 22.9% of Mo and MT patients, respectively. Sixty percent of patients with large cell undifferentiated carcinoma had elevated CA 125 (mean 176 U/ml) compared to 15.4% of patients with all other histological types of tumors combined (54.3 U/ml, p less than 0.01). CA 19.9 serum levels were also more often elevated in patients with large cell undifferentiated carcinomas (50%, 7/14 cases) than in other histological types (30%, 36/120 patients), but the difference was not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)     

A comparison of diagnostic techniques for postpartum endometritis in dairy cattle

Holstein cows (n=221) from eight commercial dairy herds were examined for endometritis between 28 and 41 days postpartum using 5 diagnostic techniques: (1) vaginoscopy; (2) ultrasonographic assessment of uterine fluid volume; (3) ultrasonographic assessment of endometrial thickness; (4) endometrial cytology collected by cytobrush; and (5) endometrial cytology collected by uterine lavage. Concordance correlation was used to evaluate the reliability of cytobrush and lavage cytology. Cytobrush cytology was found to have the greatest intraobserver repeatability (cytobrush, rho(c)=0.85 versus lavage, rho(c)=0.76) and was chosen as the reference diagnostic test. Pregnancy data at 150 days postpartum was available for 189 cows. Survival analysis was used to determine the lowest percentage of polymorphonuclear cells associated with time to pregnancy. The sensitivity and specificity of the diagnostic techniques was determined using pregnancy status at 150 days and cytobrush cytology as the diagnostic standards. The risk of non-pregnancy at 150 days was 1.9 times higher in cows with more than 8% PMNs identified using cytobrush cytology than in cows with less than 8% PMNs (P=0.04). Twenty-one cows of 189 cows (11.1%) had >8% PMNs and were considered to be positive for endometritis. Cows with endometritis had a 17.9% lower first service conception rate (P=0.03) and a 24-day increase in median days open (P=0.04). The sensitivities of all five diagnostic tests relative to 150-day pregnancy status ranged from 7.1 to 14.3% and the specificities from 84.0 to 93.3%. Relative to cytobrush cytology, the respective sensitivity and specificity values are as follows: vaginoscopy (53.9%, 95.4%); lavage cytology (92.3%, 93.9%); ultrasonographic assessment of uterine fluid (30.8%, 92.8%); and ultrasonographic assessment of endometrial thickness (3.9%, 89.2%). Endometritis impaired reproductive performance. Cytobrush cytology was the most reliable method of diagnosing endometritis in cattle.     

CA 125 in biological fluids

CA 125 is not a specific tumor marker, and is synthesized by normal and malignant cells of different origin (mainly in tissues derived from the müllerian epithelia) in a similar proportion. Abnormal CA 125 levels may be found in fluids of different origin (ascites, pleura, pericardium, amniotic fluid, cyst fluid, bronchoalveolar fluid, etc.) and in serum from patients with these fluids. Differences in serum CA 125 found in malignant or benign diseases may be related to the number of cells that synthesize the marker, and are highly dependent on the access to serum, where the marker is normally determined. Moreover, CA 125 is a very good tumor marker in ovarian and lung cancer. The sensitivity of CA 125 in ovarian cancer is related to stage (40-95%), histological type (lower levels in mucinous adenocarcinoma), and the marker is useful in the early detection of recurrence (sensitivity 80%) and in therapy monitoring. It's sensitivity in lung cancer is lower than in ovarian cancer, 39% in locoregional malignancies and 69% in metastatic disease, but clearly related to stage and histology (mainly in adenocarcinomas and large cell lung cancer) and it is useful in prognosis and disease monitoring.     

Tumor markers, liver function tests and symptoms in 115 patients with isolated colorectal liver metastases

Development of the hybridoma technique has made the identification of several new tumor antigens possible. Although it was hoped that they would be more tumor-specific, none of these markers are found exclusively in tumor or in serum of tumor patients. Compared with carcinoembryionic antigen (CEA) and liver function tests, the roles of these markers (CA 19-9, CA 125, CA 15-3) were prospectively evaluated in 115 patients with colorectal liver metastases. Patients were classified according to tumor volume (T1 less than 25%, T2 25-75%, T3 greater than 75%), and the extension of infiltration (solitary/multiple/diffuse; unilateral, bilateral). Patients with benign liver or biliary disease served as a control group (n = 63). Overall sensitivity was 87% for *1, 50% for *2 and 38% for *3, with a significant correlation with tumor size. CEA serum levels were elevated in 88% of all patients. CA 19-9 was less sensitive: positive in 59%. Because of some complementary elevations, the combined use of CEA, CA 19-9 and CA 125 raised sensitivity to 94%. CA 19-9 and LDH could be useful for confirmation because of their higher specificity; however, the specificity of CEA rose to 93% on using a cut-off of 10 ng/ml instead of 3 ng/ml. The results indicate that CEA and CA 19-9 as well as liver function tests are helpful for preoperative staging in conjunction with imaging procedures before liver resection or regional chemotherapy.     

血清CA125 和OPN 联检在卵巢癌患者中的诊断价值

目的:探讨CA125和OPN联检在卵巢癌诊断中的应用价值。方法:以50例正常健康人为对照,对经组织病理学确诊的69例卵巢癌患者和54例卵巢良性肿瘤患者术前行血清CA125(放免法)和OPN(ELISA法)测定。比较二种血清标志物在正常人、卵巢良性肿瘤和卵巢癌病例中的表达水平。以正常人血清OPN均值±1.96S作为上下界,计算OPN临界值,大于临界值即为OPN阳性。血清CA125≥35 U/mL为阳性。比较三组病例中血清CA125和OPN单检及联检的灵敏度及特异性。比较二种血清标志物在卵巢癌及卵巢良性肿瘤的不同组织分型中的灵敏度。结果:卵巢癌组血清CA125和OPN的水平均显著高于正常对照组和卵巢良性肿瘤组(P<0.01),OPN临界值为27 ng/mL。在卵巢癌诊断中CA125、OPN检测的敏感度分别为66.7%和85.5%,二者联检的敏感度为95.7%。同时二者联检对浆液性囊腺癌、粘液性囊腺癌和子宫内膜样腺癌的敏感度分别为91.7%、70.0%和66.7%。结论:血清CA125和OPN是卵巢癌诊断的敏感性指标,二者联检可提高卵巢癌、特别是粘液性卵巢癌诊断的敏感度。     

Evaluating the clinical significances of serum HE4 with CA125 in peritoneal tuberculosis and epithelial ovarian cancer

This study aimed to evaluate the clinical significances of human epididymis protein 4 (HE4) with cancer antigen 125 (CA125) in differential diagnosis between epithelial ovarian cancer (EOC) and peritoneal tuberculosis (PTB). We retrospectively reviewed data of 31 patients suspected preoperatively as having EOC but whose pathological results revealed PTB. The concentrations of serum HE4 and CA125 in PTB were significantly lower than that in EOC. The optimal cutoffs to differentiate EOC from PTB were HE4?>?151.4?pmol/l and CA125?>?563.5?U/ml, which means EOC may be considered if HE4 or CA125 was greater than the cutoff, otherwise, PTB should not be neglected. Furthermore, the specificity and accuracy for differentiating PTB form EOC could be improved when combination HE4 and CA125. Conclusively, the combination of HE4 and CA125 may be recommended as potential biomarkers in the preliminary differential diagnosis of PTB from EOC before the “golden standard” of pathologic diagnosis finally obtained.

血清AFP,CEA,CA125单独或联合检测对原发性肝癌早期诊断的临床价值研究

目的:探讨血清中甲胎蛋白(AFP)、癌胚抗原(CEA)、糖类抗原125(CA125)单独以及联合检测对于原发性肝癌的早期诊断临床价值。方法:选择2012年1月~2016年6月在我院检验科确诊的120例原发性肝癌患者作为观察组,并以80例健康志愿者作为对照组,检测和比较两组的AFP、CEA和CA125水平,分析血清AFP、CEA、CA125单项及联合检测检出原发性肝癌的阳性率和约登指数。结果:观察组血清AFP(319.53±35.78 ng/mL)、CEA(81.4±27.8 ng/mL)、CA125(20.67±4.61 ng/mL)水平均明显高于健康对照组(P0.05)。血清AFP、CEA、CA125在单独检测时诊断原发性肝癌的敏感性分别为65%(78/120)、75%(90/120)和60%(72/120),而三者的联合检测能够使检测的敏感性达到92%(112/120),显著高于单独检测时的敏感度(P0.05)。血清AFP、CEA、CA125单项检测约登指数均显著低于联合检测(P0.05)。结论:相较于血清AFP、CEA、CA125的单独检测,三者联合检测可明显提高原发性肝癌的检出率。     

Density distribution and immunological reactivity of tumor cells from peritoneal effusions of patients with ovarian neoplasms.

Ascitic samples from 19 patients with primary ovarian non-mucinous carcinomas, three with Krukenberg tumors and eight with noncancerous peritoneal effusions were studied by conventional cytology and immunocytochemical staining. Density gradient centrifugation was applied to fractionate ascitic fluid cells. The enrichment of cell types by this method facilitated their cytomorphological characterization and identification of neoplastic cell subpopulations existing in peritoneal effusions. Immunophenotypic studies of cells were made using monoclonal antibodies (mAbs) against ovarian carcinoma-associated antigens (OC 125, 10B, 8C) and carcino-embryonic antigen (CEA). Non-specific cross-reacting antigen (NCA) was applied as a marker for granulocytes which often accompany peritoneal effusions. Our results indicated that immunofluorescence (IF) staining contributed to the distinction between the primary and secondary ovarian carcinomas. Density gradient centrifugation appeared to be a useful method for separation of mesothelial cells.     

SM047 immunoreactivity in peritoneal fluids

SM047 is a recently developed monoclonal antibody generated against an ovarian adenocarcinoma cell line. A recent immunohistochemical study has shown that SM047 is strongly expressed in tissue sections of most ovarian serous adenocarcinomas. This study aimed to ascertain whether SM047 staining is of value in cytological preparations of peritoneal fluid. A total of 206 consecutive peritoneal fluids were stained immunocytochemically with SM047, CA125, monoclonal carcinoembryonic antigen (mCEA), Ber-EP4 and cytokeratins (CK7 and 20). SM047 positivity was present in reactive mesothelial cells in 117 of 141 (83%) benign cases in which these were present. SM047 positive tumour cells were present in 22 of 23 (96%) ovarian serous adenocarcinomas and in small numbers of gastric adenocarcinomas (two of three), mesotheliomas (one of two) and pancreatic adenocarcinomas (one of one). All six colorectal and two breast adenocarcinomas were negative with SM047. Reactive mesothelial cells in all cases were positive with CK7 and in most cases with CA125. They were negative with CEA, Ber-EP4 and CK20. All adenocarcinomas were positive with Ber-EP4 and mesothelial cells were always negative. All colorectal adenocarcinomas were positive with CK20. This study shows that SM047 staining may be of value in the diagnosis of an ovarian serous adenocarcinoma in peritoneal fluids. Negative staining helps to exclude a primary ovarian serous adenocarcinoma and is characteristic of colorectal adenocarcinoma. The small numbers of other malignancies in the study precludes a judgement of the value of SM047 staining in these neoplasms. SM047 staining may be useful, as part of a larger panel, in the work up of patients with peritoneal effusions.

Evaluation of serum CA 125 levels in patients with pelvic pain related to endometriosis

The aim of the study was to investigate the clinical value of the serum CA 125 level for diagnosing and determining the severity of endometriosis and pelvic pain associated with endometriosis. Eighty-six women who underwent operative laparoscopy were enrolled. Sixty-nine women with endometriosis and 17 without endometriosis participated in this study. In all of the patients, endometriosis was diagnosed and classified into stages according to the Revised American Fertility Society (R-AFS) classification. The mean serum CA 125 levels were determined in each patient. We also investigated the relationship between serum CA 125 concentration and the intensity of dysmenorrhea and dyspareunia in the study group. The mean serum CA 125 levels of women with endometriosis were higher than those of the control group (p<0.050). However, the mean serum CA 125 levels were higher in stage IV than in other stages of endometriosis according to the R-AFS classification. On the other hand, the percentage of patients with serum CA 125 levels >35 U/mL was elevated in the subgroups with severe dyspareunia and severe dysmenorrhea versus the asymptomatic subgroup but the differences had no statistical significance. In conclusion, CA 125 serum levels were related to endometriosis and R-AFS score in the evaluated patient series. No correlation was found between serum levels of CA 125 and pelvic pain in patients with endometriosis.

目的:探究伊立替康联合卡铂辅助化疗对宫颈癌患者血清叶酸、CA125及临床疗效的影响。方法:选择我院收治的宫颈癌患者41例,随机分成实验组和对照组。对照组19例予广泛全子宫切除及盆腔淋巴结清扫术;实验组22例在行全子宫切除及盆腔淋巴结清扫术前予卡铂和伊立替康治疗。对比两组的临床疗效以及治疗前后患者血清叶酸及CA125水平的变化。结果:实验组患者的有效率(81.8%)高于对照组(47.4%),其差异有统计学意义(P0.05);治疗后,两组患者的血清CA125水平均降低、叶酸水平均升高(P0.05),其差异有统计学意义;与对照组相比,实验组叶酸水平较高、血清CA125水平较低(P0.05),差异有统计学意义。结论:伊立替康联合卡铂辅助化疗对宫颈癌患者有较好的临床疗效,推测其机制可能与降低患者CA125水平及提高叶酸水平有关。     

Changes in the expression of serum markers CA242, CA199, CA125, CEA, TNF-α and TSGF after cryosurgery in pancreatic cancer patients

The presence of serum tumor markers, carbohydrate antigen 242 (CA242), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), tumor-supplied group of factors (TSGF) and tumor necrosis factor-α (TNF-α), is closely associated with invasion and metastasis of many malignancies. The expression of these markers were measured in serum taken from 37 pancreatic cancer patients prior to treatment. Levels of CA242, CA199, CA125, CEA and TNF-α expression correlated with tumor size, clinical stage, tumor differentiation, lymph node and liver metastasis (P < 0.05). One month after cryosurgery, serum levels of these markers were significantly reduced compared with levels prior to cryosurgery (P < 0.05), whereas there was no significant difference was found between serum levels before and after chemotherapy (P > 0.05). Thus, cryosurgery is more effective than chemotherapy for decreasing CA242, CA199, CA125, CEA, TSGF and TNF-α serum levels in these patients.
