Objective To study the clinical singificance of serum tumor markers (CA153, CA125 and CEA) in doagnosis of breast cancer. Methods Electrochemiluminescence immunoassay (ECLIA) was used to analyze serum levels of CA153,CA125 and CEA in 55 patients with breast canc-er (breast cancer group),20 patients with benign breast lesions (benign breast lesion group) and 20 healthy controls (healthy control group). Results The levels of CA153, CA125 and CEA in breast cancer group were significantly higher than those in healthy control group (P<0.05); the levels of CEA and CA153 in breast cancer group were significantly higher than those in benign breast lesion group (P<0.05);the level of CA153 in postoperative patients was statistically lower than that in pre-operative patients (P<0.05);the levels of CEA and CA153 in breast cancer patients with stage Ⅲ and Ⅳ were significantly higher than those in healthy controls (P<0.05); the level of CA153 with stage Ⅲ and Ⅳ was higher than that in ones with stage Ⅰ and Ⅱ. The combined dection of CA153, CA125 and CEA in breast cancer patients increased the experimental sensitivity to 53.8% and specific-ity to 83.3%. Conclusion Detections of CA153,CA125 and CEA contribute to diagnosis of breast cancer.

GSTA1基因多态性对环磷酰胺辅助化疗的乳腺癌患者预后的影响

Objective To investigate the association between the genetic polymorphisms in GSTA1 and the clinical outcome of breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy. Methods A total of 137 breast cancer patients receiving cyclophosphamide-based adjuvant chemotherapy were recruited ( 124 cases with infiltrative ductal carcinoma, 5 cases with infiltrative lobular carcinoma and 8 cases with other histological types). PCR-LDR method was used to detect the genotypes of GSTA1. Survival curves were generated by the Kaplan-Meier method, and verified by the log-rank test. Cox proportional hazards regression analysis was used to estimate the prognostic factors in multivariate analysis. Results Of the 137 breast cancer patients, the genotypic frequencies of the GSTA1 * A/* A,* A/* B and * B/* B were 67.2% ( 92/137 ), 31.4% ( 43/137 ) and 1.5% ( 2/137 ), respectively. No significant differences were found between the genotypic frequencies and groups categorization according to age, stage, lymph node metastasis, ER or PR status (x2 = 0. 722,1. 967, 3. 303, 0. 226 and 0. 709, all P ＞0. 05 ) ;through Fisher exact test, also no significant differences were found between the genotypic frequencies and group categorization according to tumor size, histological types and grading ( all P ＞ 0. 05 ) . The recurrence rates in patients with GSTA1 * A/* A and * A/* B or * B/* B genotypes were 47. 8% (44/92) and 31.1% ( 14/45 ), respectively, and the mortality rates were 22. 8% ( 21/92 ) and 17. 8% ( 8/45 ),respectively. Patients with GSTA1 * A/* B and * B/* B genotypes were significantly associated with reduced hazard of relapse (x2 =18.723, P＜0. 01)and mortality (x2 =7.352, P＜0.01), compared to cases with the common * A/* A genotypes, according to Kaplan-Meier survival analysis and log-rank test. Moreover,Cox multivariate analysis showed that GSTA1 polymorphisms appeared to be an independent risk factor for recurrence-free survival ( OR =0. 222, 95% CI:0. 108-0. 458, P ＜0. 01 ) and overall survival ( OR =0. 362,95% CI:0. 145-0. 902, P ＜ 0. 05 ). Conclusion These data indicate that GSTA1 polymorphism may be a potential prognostic factor for recurrence-free survival and overall survival in breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy.

Objective To determine the expression of Human Epidermal Growth Factor Receptor 2 (HER-2) in breast cancer and its correlation with Tumor Necrosis Factor-α (TNF-α). Methods We used SABC method to detect the expression of HER-2 and TNF-α in 112 cases of primary breast cancer, and analyzed the association of HER-2 expression with clinicopathological features and TNF-α expression. Results The positive expression rate of HER-2 in breast cancer was 35.71% (40/112), of which, the expression rate was 35.05% (34/97) in 97 invasive tubic breast cancer, and 33.33% (2/6) in invasive lobular breast cancer,25.00% (1/4) in mucinous carcinoma, and 50. 00% (2/4) in intraductal carcinoma. There was no significant correlation between HER-2 and any clinicopathological features of primary breast cancer ( P ＞ 0. 05 ). The expression of HER-2 in breast cancer had no signiciant association with TNM stage, age, age of menarche,menopause, gravidity, parity and family history of cancer ( Ps ＞ 0. 05 ), The positive rate of TNF-α was 23.61% (17/72) when HER-2 was negative, whereas the positive rate of TNF-α was 52. 50% (21/40) when HER-2 was positive. The expression of HER-2 was signiciantly positively correlated with the expression of TNF-α (r = 0. 881, P ＜ 0. 05 ). Conclusion HER-2 expression had a positive correlation with TNF-α in breast cancer,but the specific mechanism is still unclear.

目的：探讨胃癌患者外周血中CD4^＋-CD25^high-Foxp^3＋-调节性T细胞（Treg）的比例与血清中转化生长因子131（TGF-β1）、前列腺素E2（PGE2）表达水平的相关性。方法：采用流式细胞术检测26名健康体检者（对照组）和39例胃癌患者（胃癌组）外周血中CD4^＋-CD25^high-Foxp^3＋-细胞比例，同时运用ELISA法检测其血清中TGF-β1、PGE2的表达水平。结果：胃癌患者的CD4^＋-CD25^high-Foxp^3＋-细胞比例与其TNM分期相关，该比例随TNM分期上升而上升，其中TNMⅢ、Ⅳ期患者与健康对照者间的细胞比例差异有统计学意义（P〈0．01）。胃癌组和健康对照的组血清TGF-β1[（14．85±6．16）μg／L比（10．33±3．25）μg／L]和PGE2表达[（100．46±47．52）ng／L比（74．12±44．96）ng／L]间差异亦有统计学意义（P〈0．01），其中TNM Ⅲ、Ⅳ期患者TGF-β1水平与Treg相关（r=0．750，P〈0．01），而PGE2在TNM Ⅰ、Ⅱ期和TNMⅢ、Ⅳ期均与Treg相关（r=0．704，P〈0．01；r=0．748，P〈0．01）。结论：胃癌患者外周血中CD4^＋-CD25^high-Foxp^3＋-细胞比例随肿瘤的进展而增高，而其血清TGF-β1、PGE2表达水平与CD4^＋-CD25^high-Foxp^3＋-细胞116例相关。     

恶性肿瘤颈部转移淋巴结超声分区分析

目的分析不同恶性肿瘤颈部转移淋巴结的超声分区特征。方法颈部淋巴结转移恶性肿瘤患者248例,其中甲状腺癌79例,食管癌31例,喉癌23例,鼻咽癌27例,舌癌14例,上颌窦癌7例,肺癌29例,乳腺癌38例,超声分析各恶性肿瘤患者转移淋巴结分区情况。结果甲状软骨以上头颈部原发肿瘤（喉癌、鼻咽癌、舌癌、上颌窦癌）71例,其Ⅱ区淋巴结转移率（92%）高于Ⅰ、Ⅲ、Ⅳ区（49%、37%、11%）（P〈0.05）;甲状软骨以下颈部原发肿瘤（甲状腺癌、食管癌）110例,Ⅲ、Ⅳ、Ⅵ区淋巴结转移率（82%、97%、80%）高于Ⅱ、Ⅴ区（16%、35%）（P〈0.05）;头颈部外的原发肿瘤（肺癌、乳腺癌）67例,Ⅳ、Ⅴ区淋巴结转移率（96%、85%）高于Ⅲ区（16%）（P〈0.05）。结论恶性肿瘤颈部淋巴结转移超声分区特征可为临床诊断提供参考。     

结直肠癌患者测定血脂和单克隆抗体肿瘤标志物水平进行诊断的临床研究

目的 探讨结直肠癌患者测定血浆血脂和单克隆抗体肿瘤标志物水平进行诊断的临床意义.方法 96例结直肠癌患者(包括Ⅰ～Ⅱ期62例和Ⅲ～Ⅳ期34例)和30例良性结直肠瘤患者血脂和单克隆抗体肿瘤标志物CA199、CA724、CA153 水平分别由生化法和电化学发光免疫分析法进行测定,并进行了对比性研究.结果 Ⅰ～Ⅱ期结直肠癌患者血清TC、HDL-C 和HDL-C/TC比值水平较之良性结直肠瘤患者无明显差异(P均＞0.05);而Ⅲ～Ⅳ期结直肠癌患者较之良性结直肠瘤患者血清TC水平明显增高(P＜0.01),血清HDL-C和HDL-C/TC比值水平明显降低(P均＜0.01).Ⅰ～Ⅱ期和Ⅲ～Ⅳ期结直肠癌患者血清CA199、CA724和CA153水平较之良性结直肠癌患者均明显增高(P＜0.01).单克隆抗体肿瘤标记物的阳性率显示:良性结直肠瘤患者的阳性率为3.33%～13.33%,结直肠癌患者血清CA199、CA724和CA153的阳性率为39.58%、37.50%、35.40%,CA199+CA724的阳性率为58.33%.CA724+CA153的阳性率为62.50%,CA199+CA724+CA153的阳性率为84.44%.结论 结直肠癌患者血清TC水平增高和HDL-C、HDL-C/TC比值水平的降低是诊断中、晚期癌症的良好指标,单克隆抗体肿瘤标志物CA199、CA724和CA153水平的联合测定是提高结直肠癌患者阳性率的重要措施.     

CRP与T-淋巴细胞亚群联检在胃癌分期及炎症反应中的意义

目的联合检测CRP及T淋巴细胞亚群,探讨其在胃癌分期和炎症反应中的意义。方法手术前及术后7天检测78例胃癌患者外周血中的T淋巴细胞亚群与CRP水平,分析与胃癌临床分期及感染发生的关系。结果Ⅰ、Ⅱ期胃癌淋巴细胞亚群术前术后改变不明显,Ⅲ、Ⅳ期患者淋巴细胞亚群术前明显下降,术后7天增高明显(P<0.05),Ⅲ、Ⅳ期感染率明显高于Ⅰ、Ⅱ期。术前各期胃癌的CRP改变不明显,但术后7天Ⅲ、Ⅳ期胃癌上升明显(P<0.01),感染率也高于Ⅰ、Ⅱ期(P<0.05)。结论T淋巴细胞亚群及CRP在一定程度上反映了胃癌的病期。病期越晚,CRP的免疫放大作用越明显,对组织免疫损伤程度越明显。
