Multi-disciplinary modality treatment is the optimal therapeutic strategy for locally advanced squamous cell carcinoma of head and neck (SCCHN). Recently, molecular targeted agents have been tested in this setting. Epithelial growth factor receptor (EGFR) is the major therapeutic target because of its universally high expression in SCCHN. As a human-mouse chimeric monoclonal antibody, cetuximab is the only molecular targeted agent approved in SCCHN. As compared with radiotherapy alone, radiotherapy in combination with cetuximab was proved to improve progression-free and overall survival in patients with locally advanced SCCHN. However, randomized comparison between radiotherapy plus cetuximab and conventional concurrent chemoradiotherapy (CCRT) is limited in term of efficacy and toxicity. Although RTOG 0522 study demonstrated it is ineffective to combine cetuximab with CCRT, the optimal chemotherapy agent partner with cetuximab warrants further investigation. For other anti-EGFR inhibitors, how to wisely design pertinent clinical studies based on available evidence is the key for success.

Objective To discuss the application value of cancer gene c-erbB-2 and its protein products P185 in evaluation of the diagnosis and prognosis of breast cancer with lymph node metastasis,and to explore the relationship between c-erbB-2 expression and tumor pathology classification,relapse.Methods 112 cases with mammary disease were selected as the research subjects.According to different clinical diagnosis,they were divided into breast cancer lymph node metastasis group,breast cancer without metastasis group and mammary gland benign pathological change group.The c-erbB-2 gene and carcinoembryonic antigen(CEA) were detected by immunohistochemical method,enzyme-linked immunosorbent(ELISA) and electrochemical luminescence method.The c-erbB-2 protein(P185)and CEA of the three groups were compared,the sensitivity and specificity of c-erbB-2 expression and CEA in the diagnosis of breast cancer with lymph node metastasis were analyzed.At the same time,the relationship between cerbB-2 expression and tumor pathology classification,relapse was analyzed.Results P185 and CEA index of breast cancer lymph node metastasis group and breast cancer without metastasis group were significantly higher than those of mammary gland benign pathological change group(t =7.093,6.443,9.232,8.508,all P ＜ 0.0 1),and P185 index of breast cancer lymph node metastasis group was significantly higher than without metastasis group (t =2.281,P ＜0.05),and there was no significant difference of CEA between the two breast cancer groups (t =0.406,P ＞ 0.05).The sensitivity of c-erbB-2 expression in dignosis of breast cancer lymph node metastasis had no difference with CEA (x2 =0.632,P ＞ 0.05),but the specificity was significantly higher than CEA(x2 =11.900,P ＜ 0.01).The positive expression rate of c-erbB-2 and tumor pathology classification had no obvious relation:Postoperative recurrence rate of c-erbB-2 positive expression patients was significantly higher than the negative expression patients(x2 =5.141,P ＜0.05).Conclusion c-erbB-2 gene and its protein product has good sensitivity and specificity in the diagnosis of breast cancer lymph node metastasis,and has obvious correlation with postoperative breast cancer recurrence,has important reference value in evaluation of the diagnosis and prognosis of breast cancer.

Objective To explore the clinical signifcance of changes of serum Ang Ⅱ,hs-CRP and BNP levels and the relationship with atrial fibrillation(AF),and the risk factors of AF recurrence.Methods 100 patients with AF were selected in this study,and they were divided into two groups:paroxysmal atrial fibrillation group (n =54),durative atrial fibrillation group(n =46),and 50 healthy subjects were selected as control.The levels of serum Ang Ⅱ,BNP were detected by radioimmunoassay,and hs-CRP was detected by immunoturbidimetry.Results The levels of Ang Ⅱ,hs-CRP and BNP in atrial fibrillation patients were significantly increased as compared to control group (P ＜ 0.01).The levels of Ang Ⅱ,hs-CRP in the durative atrial fibrillation group were higher than those in the paroxysmal atrial fibrillation group.The levels of serum Ang Ⅱ,hs-CRP were positively correlated with serum BNP level (r =0.563,0.678,all P ＜0.01).The level of serum Ang Ⅱ was positively correlated with serum hs-CRP level(r =0.626,P ＜ 0.01).Multiple logistic regression analysis revealed that hs-CRP and BNP were the important risk factors of atrial fibrillation recurrence[OR value =2.42,95％ CI(1.84 ～ 5.26) ;OR value =2.14,95％ CI(1.37 ～.86)].Conclusion The serum AngⅡ,hs-CRP and BNP may play important roles in the development of AF.hs-CRP and BNP may be the independent risk factors of AF.The detection of hs-CRP and BNP may be related to recurrence prognosis in patients with AF.
