测定血清CA125水平在卵巢癌的临床意义

目的分析卵巢癌手术前后测定血清CA125水平的临床意义.方法采用回顾性分析方法,1994年1月～2000年8月我院收治的137例卵巢癌患者手术前后血清CA125水平结合病理、分期、分化、手术情况\治疗及预后等临床资料进行分析.结果在卵巢癌,术前血清CA125水平与病理类型及分期相关(P=0.006),术后2～4个月血清CA125水平与手术的癌细胞减灭程度相关(P=0.025),术后5～7个月血清CA125水平与是否坚持化疗相关(P=0.014),且为预测复发及生存时间的重要因素.术后血清CA125水平的升高可预测复发,其敏感性为87.5%,且通常较临床证实复发提前,平均为7.2个月.结论卵巢癌患者术前测定血清CA125水平可初步反映病理类型及分期,术后监测血清CA125水平可反映手术的肿瘤减灭程度,及时预测复发,并可判断预后.     

晚期卵巢上皮性癌患者初次治疗过程中血清CA125水平变化与其预后的关系

目的 探讨晚期(Ⅲ～Ⅳ期)卵巢上皮性癌(卵巢癌)患者初次治疗过程中血清CA125水平变化与其预后的关系.方法 选择1998年1月-2003年12月间中山大学肿瘤防治中心妇瘤科收治的142例晚期卵巢癌患者,回顾性分析其初次治疗过程中血清CA125水平的变化,采用Kaplan-Meier法计算其累积生存率,并采用Cox风险比例回归模型分析血清CA125水平的变化对患者预后的影响.结果 根据患者治疗前血清CA125水平不同分为≤500、>500～1500和>1500 kU/L,其3年累积生存率(分别为64%、71%及64%)比较,差异无统计学意义(P>0.05).术后接受3个疗程化疗后,血清CA125水平降至正常(0～35 kU/L)的77例患者的3年及5年累积生存率分别为84%及56%,明显高于血清CA125水平仍为异常的48例患者(分别为42%、15%,P<0.01).多因素分析表明,残留灶直径(P<0.01)及3个疗程化疗后血清CA125水平(P<0.01)是影响晚期卵巢癌患者预后的独立的因素.进一步分层分析表明,接受了满意的肿瘤细胞减灭术(残留灶直径≤1 cm)的患者中,3个疗程化疗后血清CA125水平降至正常者的3年及5年累积生存率分别为88%、64%,明显高于化疗后血清CA125笛水平仍为异常者(分别为52%、18%,P<0.01);同样,接受了不满意的肿瘤细胞减灭术(残留灶直径>1 cm)的患者中,3个疗程化疗后血清CA125水平降至正常者的3年和5年累积生存率分别为74%、32%,明显高于化疗后血清CA125水平仍为异常者的33%、13%(P<0.01).结论 3个疗程化疗后血清CA125水平正常与否可预测晚期卵巢癌患者的预后,且无论初次手术是否为满意的肿瘤细胞减灭术,3个疗程化疗后血清CA125水平降至正常者较未降至正常者预后好.

以Krukenberg瘤为首发表现胃癌55例临床分析

目的比较Krukenberg瘤为首发表现的胃癌患者与原发卵巢上皮性癌患者的临床病理资料,探讨前者的临床病理特征。方法回顾性分析2005年9月至2013年9月郑州大学第一附属医院妇产科以Krukenberg瘤为首发表现的胃癌患者55例（Krukenberg瘤组）的临床资料,同期原发卵巢上皮癌患者55例（原发卵巢癌组）作为对照。结果 Krukenberg瘤组患者的平均年龄为（35.1±4.6）岁（20~56）岁,显著低于原发卵巢癌组的（57.2±6.8）岁（40~72）岁（P〈0.05）。Krukenberg瘤组合并腹水比例（34.5%,9/55）明显低于原发卵巢癌组（90.9%,50/55;P〈0.05）。Krukenberg瘤组血清CA125升高30例,平均CA125水平为（98.7±14.1）kU/L;原发卵巢癌组CA125升高55例,平均CA125水平为（473.9±123.9）kU/L;两组CA125水平比较,差异有统计学意义（P〈0.05）。Krukenberg瘤组术前术后诊断符合率（9.1%,5/55）明显低于原发卵巢癌组（100.0%,55/55;P〈0.05）。Krukenberg瘤组病理类型多为胃印戒细胞癌（49.1%,27/55）,原发卵巢癌组多为浆液性囊腺癌（74.5%,41/55）。Krukenberg瘤组患者6个月生存率为54.5%（30/55）,1年生存率为36.4%（20/55）,3年生存率为3.6%（2/55）;原发卵巢癌组分别是72.7%（40/55）、60.0%（33/55）和23.6%（13/55）。结论以Krukenberg瘤为首发表现的胃癌患者病理类型以胃印戒细胞癌为主,术前诊断率低,预后差,患者多为中青年妇女,合并腹水比例较低,血清CA125的测定及PET-CT检查对鉴别诊断有重要价值。     

CA125 regression during neoadjuvant chemotherapy as an independent prognostic factor for survival in patients with advanced ovarian serous adenocarcinoma

OBJECTIVE: The associations of the CA125 regression rate with initial response to chemotherapy and prognosis remain unclear. We examined the association between CA125 regression in neoadjuvant chemotherapy (NAC) and prognosis. METHODS: Fifty patients with advanced ovarian cancer (TNM classification TIIIc or M1) who received initial NAC and did not undergo significant cytoreductive surgery were selected for the retrospective analysis, after excluding clear cell carcinoma and mucinous adenocarcinoma putative to be cisplatin-resistant. For each patient, regression coefficient was calculated using all the CA125 levels measured from the day of NAC as day 0 until the day of normalization of CA125 level (<35 IU/ml) or the day of standard surgery. Responder was defined as a regression coefficient of -0.039 or greater (33 cases) and nonresponder as a regression coefficient less than -0.039 (17 cases). RESULTS: The 3-year survival rate for all 50 cases was 59.3%. When stratified by regression coefficient of CA125 levels, the 3-year survival was 70.5% in responders and 43.3% in nonresponders. Univariate analysis identified the regression coefficient of CA125 as a significant prognostic factor for overall survival (P = 0.012; log lank test). Residual tumor at standard surgery after NAC and absolute CA125 level were not significant prognostic factors. CONCLUSIONS: Based on the CA125 regression rate, it is possible to stratify TIIIc or M1 ovarian serous adenocarcinoma cases into those with a good prognosis of survival and those with poor prognosis. Regression coefficient of CA125 level greater than -0.039 predicts good 3-year survival after subsequent radical surgeries.     

CA125、D-二聚体在卵巢癌中的应用价值

卵巢癌发病率在妇科恶性肿瘤中居第3位,而病死率却居首位。卵巢癌起病隐匿,早期缺乏典型临床表现,易发生腹腔内播散转移,70%的患者就诊时已属晚期。虽然目前卵巢癌可经肿瘤细胞减灭术辅以化疗得到有效治疗,但因其复发率较高,晚期患者5年存活率仅为30%左右。早期诊断、有效治疗、降低复发对卵巢癌的预后有重要影响。研究者致力于寻找指标,如CA125、D-二聚体,以应用于卵巢癌的早期诊断、疗效观察及预后评估。综述CA125、D-二聚体在卵巢癌中的应用价值。     

Prognostic significance of CA 125 and TPS levels after 3 chemotherapy courses in ovarian cancer patients

OBJECTIVE: To evaluate the prognostic significance of and predictive value for survival of CA 125 and TPS levels after three chemotherapy courses in ovarian cancer patients. METHODS: We analyzed in a prospective multicenter study the 1- and 2-year overall survival (OS) in ovarian carcinoma patients. The prognostic significance of CA 125 and TPS levels above the discrimination value (25 kU/L and 100 U/L, respectively) was examined by univariate and multivariate analyses. RESULTS: Of the 213 cases included, 64 patients were staged as FIGO I + II and 149 patients were staged as FIGO III + IV. Tumor marker levels in stage I + II were not correlated with survival. However, stage III and IV patients with elevated levels of CA 125 or TPS after three chemotherapy courses had a worse 2-year OS (69% vs 26%, P < 0.0001 and 57% vs 20%, P < 0.0001, respectively) than patients with normal levels of the markers. In univariate analysis the result of operation (staging laparatomy and partial debulking) and advanced FIGO stage (IV) were also adverse prognostic factors. Independent factors predictive of low 2-year OS by multivariate analysis were staging laparotomy, TPS elevated, and CA 125 elevated. The only factors predictive of low 1-year OS were TPS elevated and staging laparotomy. CONCLUSIONS: Ovarian cancer patients with elevated CA 125 levels after three chemotherapy courses have a poor prognosis. However, the prognostic accuracy can be significantly increased by the parallel determination of serum TPS.     

The prognosis of ovarian cancer depends on the CA125 value at the end of induction therapy

The prognosis of ovarian cancer depends on the CA125 value at the end of induction therapy. The relationship between the prognosis and the CA125 value at the end of induction therapy was analysed in 16 ovarian cancers. In the group with a CA125 value less than 35 units/ml after the induction therapy (initial surgery + 3 courses of chemotherapy) all patients have survived for 18-45 months since the initial treatment to the present, whereas in the group with a CA125 value above 35 units/ml all patients died within 16 months after the initial treatment. Comparison of the survival rates in these two groups showed a significant difference. These results suggest that the most important factor that affects prognosis in patients with ovarian cancer is the normalization of the CA125 value after the induction therapy.     

Serum CA125 assay at the time of relapse has no prognostic relevance in patients undergoing chemotherapy for recurrent ovarian cancer: a multicenter Italian study

The present retrospective study assessed the prognostic value of serum CA125 assay at relapse in 73 patients with recurrent epithelial ovarian cancer. At the time of relapse, serum CA125 levels ranged from 7 to 7000 U ml⁻¹. The 25%, 50% and 75% quantiles of CA125 levels were 76, 178 and 339 U ml⁻¹, respectively. Antigen values were >35 U ml⁻¹ in 67 (91.8%) of the 73 patients. Median time to recurrence was 16 months (range, 4–62 months). Serum CA125 levels at relapse were not related to site of recurrence, time to recurrence, FIGO stage, histologic type, tumor grade and residual disease after initial surgery. Sixty patients received salvage chemotherapy at relapse. In these patients survival after recurrence was significantly related to time to recurrence ( 6 months vs < 6 months, P  = 0.0371; 12 months vs >12 months, P  = 0.0014; 16 months vs >16 months, P = 0.0001), but not to CA125 level at relapse (at any cut-off value for the antigen: 35, 76, 178 and 339 U ml⁻¹ ), site of recurrence, FIGO stage, histologic type, tumor grade and residual disease after initial surgery. In conclusion, time to recurrence was the only variable predictive of further survival in patients undergoing salvage chemotherapy for recurrent ovarian cancer, whereas serum CA125 level at relapse had no prognostic relevance.     

卵巢癌早期诊断的血清肿瘤标志物研究进展

卵巢癌死亡率居妇科恶性肿瘤之首。由于早期临床症状隐匿,缺乏有效的早期诊断方法,超过70％的患者就诊时已是临床晚期。早期卵巢癌患者5年生存率为70％-90％,而晚期卵巢癌患者的5年生存率仅为20％。因此．早期诊断对卵巢癌的预后有重要影响。近年研究者致力于寻找特异度、灵敏度高的血清肿瘤标志物,如CA125、卵巢癌差异蛋白4（HE4）、可溶性间皮素相关蛋白（SMRP）、人激肽释放酶（Hk）、CA72-4和骨桥蛋白（OPN）等。以及血清标记物的联合检测,并取得一系列进展。对卵巢癌早期诊断的血清肿瘤标志物研究进展综述。
