Tumor tissue CA125 in ovarian carcinoma patients with normal serum levels

A good correlation between elevated serum CA125 and its immunolocalization in ovarian tumor tissue has been reported. This study was undertaken in order to assess the presence of CA125 in tumor tissue obtained from ovarian carcinoma patients with normal serum levels. Eleven such ovarian carcinoma patients (nine of them serous) were identified. In seven the level was normal prior to the initial operation, and in four, prior to a positive second-look operation. Immunohistochemical staining of paraffin sections for CA125 was positive in seven of the tumor tissue samples. Tumor tissue of most ovarian carcinoma patients with a preoperative normal serum CA125 contains the antigen, but an undetermined mechanism prevents elevated serum levels.     

A study of serum CASA and CA 125 levels in patients with ovarian carcinoma

The assays of Cancer Associated Serum Antigen (CASA) and CA 125 were assessed in the management of patients with ovarian cancer. It was shown that CASA is sensitive to ovarian carcinoma, and both CASA and CA 125 are more useful when used in conjunction.     

A CA125 score as a prognostic index in patients with ovarian cancer

Summary Due to its high specificity (90%) and sensitivity (86%) measurement of CA125 has become well-established in patients with epithelial ovarian cancer. We have formulated a CA125 prognostic score and examined its validity as an additional prognosis index. This score is composed of two CA125 values (one determined preoperatively and one 1 month after operation). CA125 serum levels of 0–64 IU/ml received 1 point, levels of 65–299 IU/ml were given 2 points, and those >300 IU/ml were given 3 points. These points are added to produce the CA125 prognostic score. Statistical comparison demonstrated that patients with scores of 2 or 3 had a significantly (P=0.0005) better prognosis than patients with scores of 4, 5 or 6. The classical prognostics features such as the FIGO stage, residual tumor mass and ascites were found to correlate with the CA125 prognostic score.     

A retrospective study of preoperative CA 125 levels in 82 patients with ovarian cancer

Introduction. The aim of our study was to investigate preoperative serum CA 125 as a prognostic factor in patients with ovarian carcinoma.Methods. A retrospective analysis was conducted on 82 patients with ovarian carcinoma treated at our Unit between 1998 and 2000 who had a serum CA 125, evaluated by a commercially available radioimmunoassay, prior to cytoreductive surgery. We looked for an association between preoperative CA 125 and known prognostic factors of ovarian cancer. We compared outcomes of patients with preoperative CA 125 at or below to 500 U/ml with outcomes of patients with preoperative CA 125 above 500 U/ml.Results. A significant (p<0.002) correlation between stage and CA 125 serum levels was found as 16 out of 18 stage I–II patients (89%) had CA 125 level 500 U/ml and 36 out of 64 stage III–IV patients (56%) had CA 125 level >500 U/ml. Among stage III and IV patients there was nonstatistically significant relation between serum CA 125 and histologic grade (G1+G2 vs. G3) and residual disease (<1 cm vs. >1 cm) after primary cytoreductive surgery. Preoperative serum CA-125 level did not predict either recurrences or disease free interval.Conclusion. Preoperative CA 125 correlated well with FIGO stage but not with age, grade, residual disease after primary surgery, relapse and disease free interval.     

血清CA125半衰期判定卵巢上皮性癌预后的价值

目的 探讨血清ＣＡ１２５半衰期在卵巢上皮性癌中的预后价值。方法 回顾性分析３０例卵巢上皮性癌患者在化疗过程中血清ＣＡ１２５半衰期值（ｔ１／２）与生存时间的关系。结果 血清ＣＡ１２５半衰期值（ｔ１／２）≤２０天组的中位生存时间为３６个月,ｔ１／２〉２０天组中完全缓解率为２７．３％,两者存在极显著差异（ｐ＝０．００１）。多因素生存分析表明：ＣＡ１２５半衰期和细胞分级、残余瘤灶大小均是独立的预后因素。结     

CA125 expression pattern, prognosis and correlation with serum CA125 in ovarian tumor patients. From The Danish "MALOVA" Ovarian Cancer Study

OBJECTIVES: To determine the CA125 tissue expression levels in borderline and invasive epithelial ovarian tumor tissues. Secondly, to evaluate whether CA125 tissue expression levels correlate with clinico-pathological parameters and serum CA125 levels and finally to investigate the prognostic value of tissue CA125 expression levels in ovarian cancer (OC) patients. METHODS: We designed tissue arrays (TA) and analyzed the CA125 expression in tissues from 778 Danish women with an ovarian tumor. Furthermore, corresponding preoperative blood samples obtained before surgery were collected from 382 women with OC. RESULTS: Significantly more CA125 expression positive tumors (no expression vs. expression) were found in the serous subtype compared to the percentage of positive tumors in mucinous, endometroid and other subtypes for patients both with borderline ovarian tumors and with OC (p<0.00001, p<0.00001). Similarly, a positive significant correlation was found between elevated serum CA125 levels and elevated levels of CA125 tissue expression (N=382 stage I-IV OC, Spearman rho=0.31, p<0.0001) (N=206 stage III OC, Spearman rho=0.30, p<0.0001). We found a significantly shorter survival for stage III/IV OC patients with no CA125 tissue expression compared to stage III/IV OC patients with positive CA125 tissue expression (p=0.0003). CONCLUSION: Our finding that tissue CA125 expression was lacking in late stage primary OC tumor of Danish women with poor survival may be of value in selecting patients as eligible candidates for individually based treatments.     

Significance of CA 125 serum level in discrimination between benign and malignant masses in the pelvis

Aim Our aim was to confirm that preoperative CA 125 serum level can be useful for discrimination between benign and malignant masses in the pelvis.Methods Preoperative CA 125 serum level was analyzed retrospectively in 121 patients who had surgery because of a malignant ovarian tumor and in 91 patients with benign masses in the pelvis. The cutoff serum level CA 125 between benign and malignant masses in the pelvis was 35 and 65 IU/ml.Results Of those patients with a malignant ovarian tumor, 65.3% had menopause whereas only 31.5% of those with a benign tumor did so. The average age of the patients with a malignant tumor was 54.2 years and of those with a benign tumor 46.8 years. The preoperative CA 125 serum level was higher than 35 IU/ml in 80.2% and higher than 65 IU/ml in 72.7% of all analyzed patients with a malignant tumor, whereas it was 23.9% and 9.8% respectively in patients with a benign mass. In early stage ovarian cancer disease (borderline stage, I/II) the preoperative CA 125 serum level was higher than 35 IU/ml in 67.8% and in 52.5% higher than 65 IU/ml. In advanced stages (III/IV), it was higher than 35 and 65 IU/ml in 96.1%. After therapy the CA 125 serum level dropped below 35 IU/ml in 70.8% and after three chemotherapy courses in 78.1%. A CA 125 level less than 35 IU/ml was achieved by therapy in 84.2% patients with an early stage disease (I/II) and in 62.1% in advanced stages (III/IV). The calculated sensitivity was 80.2% and negative 74.5% (CA 125 higher than 35 IU/ml) and 72.7%, 90.2%, 90.7%, 71.6% respectively (CA 125 higher than 65 IU/ml).Conclusion Preoperative determination of CA 125 is a very useful method to discriminate between benign and malignant masses in the pelvis.     

卵巢良性肿块伴腹水和血清CA125升高的临床分析--附三例报告

目的 探讨卵巢良性肿瘤伴腹水和血清CA125升高的临床特征。方法 对我院收治的3例患者进行临床分析并复习相关文献。结果 3例患者术前均误诊为卵巢癌而手术治疗,并均于手术中确诊;术前均无恶性肿瘤的诊断证据,如病理学和(或)细胞学阳性发现,也无特征性的超声表现。该类疾病以盆腔结核性肿块、卵巢子宫内膜异位囊肿和卵巢纤维瘤最常见,其他的有卵巢泡膜纤维瘤、腺纤维瘤、卵巢甲状腺肿、卵巢泡膜细胞瘤、卵巢良性Brenner瘤、卵巢成熟畸胎瘤、卵巢水肿和卵巢纤维瘤样变。结论 盆腔肿块伴腹水和血清CA125升高,并不能立即诊断卵巢癌。病理学和细胞学检查是惟一确诊的方法;对可疑病例腹腔镜检查是简便、可靠的方法。     

CA 125 in serum and tumor from patients with uterine sarcoma

Serial serum samples of 33 patients with primary sarcoma of the uterus were analyzed for CA 125 and frozen tissue sections of tumor from 23 patients were tested for this antigen. Before treatment, 12 of 30 evaluable patients showed serum CA 125 levels> 16 Uml⁻¹ (40%). There was no relationship between serum CA 125 level and the histologic subtype. Patients with serum CA 125> 16 Uml⁻¹ showed extrauterine tumor sites in 67% of the cases versus 33% in patients with normal CA 125 determinations ( P = 0.026). In (FIGO) stages I and II, elevated serum CA 125 levels prior to surgery were associated with a poor prognosis ( P = 0.043). Patients with recurrent or progressive disease demonstrated serum CA 125 levels> 16 Uml⁻¹ in 14 of the 20 cases (70%). Sarcoma cells were completely negative for CA 125, whereas positivity was observed in the epithelial component of mixed Müllerian tumors. The source of the elevated serum CA 125 levels in patients with uterine sarcoma may be stimulated mesothelial cells.     

175例子宫内膜异位症患者血清CA125水平的回顾性分析

目的:分析子宫内膜异位症患者合并子宫内膜息肉的情况,探讨血清CA125水平与痛经、内异症rAFS分期、病灶部位的相关性,为临床上更好地解读CA125水平提供依据。方法:回顾性分析2010年1月至12月我院术中或术后病理诊断为子宫内膜异位症的175例患者的临床资料。结果:(1)20.0%的子宫内膜异位症患者合并子宫内膜息肉;(2)36.6%的内异症患者有中、重度痛经,痛经程度与血清CA125水平无相关性;(3)Ⅰ期、Ⅱ期、Ⅲ期、Ⅳ期内异症患者的平均CA125水平分别为21.5U/ml、28.4U/ml、38.6U/ml、57.1U/ml,Ⅲ～Ⅳ期内异症患者血清CA125水平高于Ⅰ～Ⅱ期患者(P<0.05);(4)腹膜型、混合型、卵巢型内异症患者血清CA125的阳性率分别为21.4%、63.0%和67.4%,混合型、卵巢型内异症患者血清CA125阳性率显著高于腹膜型(P<0.001)。结论:血清CA125水平不能作为内异症合并子宫内膜息肉的预测指标;血清CA125水平可用于辅助鉴别内异症的分期和病灶部位,但是CA125对于内异症的早期诊断缺乏敏感性。     

血清CA125检测在子宫内膜癌中的价值

目的探讨血清CA125在子宫内膜癌中的价值.方法选取1992年3月～2002年3月在北京大学第一附属医院、北京大学人民医院住院经手术治疗的子宫内膜癌患者141例,术前及随访中用放射免疫法测定血清CA125水平,CA125≥35 U/ml 为阳性结果.对其中14例行子宫内膜癌组织CA125免疫组化方法检测.收集患者的临床病理资料,分析CA125与这些资料的关系以及复发患者复发前后CA125变化.结果 CA125免疫组化检测14例均呈阳性,阳性细胞着色率与血清CA125之间无明显相关.141例患者术前血清CA125阳性32例(22.7%), Ⅰ、Ⅱ、Ⅲ和Ⅳ期患者血清CA125阳性(阳性率)分别为11例(12.1%)、6例(31.6%)、12例(46.2%)和3例(60.0%). 血清CA125阳性率随子宫内膜癌期别的增加而升高.深肌层浸润、宫颈受累、附件转移、腹腔洗液细胞学阳性、盆腔淋巴结转移及宫内肿瘤病灶≥2 cm者,血清CA125阳性率增加.随访中13例复发,其中9例术前血清CA125＞35 U/ml者复发时均伴血清CA125水平升高,而另4例术前血清CA125正常者,复发后血清CA125水平仍正常.结论子宫内膜癌患者术前血清CA125的测量有助于了解肿瘤的侵犯范围.术前血清CA125水平异常的子宫内膜癌患者,术后定期复查血清CA125水平,将有助于子宫内膜癌病情的监测.

血清SCCAg及CA125在诊断宫颈鳞癌及评价预后中作用的研究

目的:探讨血清SCCAg及CA125用于宫颈鳞癌诊断、手术治疗及预后的价值。方法:选取ⅠA2～ⅡA期宫颈鳞状细胞癌为研究组,20例CIN及20例慢性宫颈炎分别为对照组1和对照组2。采用固相夹心法酶联免疫吸附实验(ELISA)检测血清SCCAg的数值,采用化学发光免疫分析法(CLIA)检测血清CA125数值。比较分析血清SCCAg及CA125与宫颈鳞癌临床病理特征、手术疗效及预后的关系。结果:宫颈鳞癌组术前血清SCCAg及CA125水平均高于慢性宫颈炎组,差异均具有统计学意义(P<0.01)。宫颈鳞癌组术前SCCAg水平高于CIN组,差异有统计学意义(P<0.001);宫颈鳞癌组术前CA125水平与CIN组的差异无统计学意义(P=0.049,P>0.0167)。血清SCCAg、CA125诊断宫颈鳞癌的临界值分别为1.03ng/ml、8.16U/ml。血清SCCAg、CA125及两项联合诊断宫颈癌的ROC曲线下面积分别为0.954、0.718、0.960,两项联合后诊断性能无明显增加。宫颈鳞癌术前血清SCCAg随临床分期增加具有线性增加的趋势。脉管有否癌栓、盆腔淋巴结有否转移也与术前血清SCCA水平有关,差异有统计学意义(P=0.011,P=0.043)。宫颈鳞癌组手术治疗后的血清SCCAg及CA125水平均有逐渐降低趋势,差异有统计学意义(P均<0.001)。结论:血清SCCAg对宫颈鳞癌有较高的诊断价值,可考虑作为诊断及手术疗效评估指标之一,有助于初步判断脉管及盆腔淋巴结转移。血清CA125对于宫颈鳞癌诊断、手术评估及随访的价值均低于SCCAg,与SCCAg联合不能增加诊断的敏感度和特异度。     

Serum CA 125 levels and survival in advanced ovarian cancer

We made a retrospective analysis of 85 patients with elevated serum CA 125 after surgery for ovarian cancer. Absolute CA 125 serum levels were a poor guide to prognosis. However, the ratio between the serum CA 125 after the first, second, or third course of treatment and the postoperative value was an excellent guide to prognosis. These were also independent and stable in the Cox Regression analysis.
