ABSTRACT
Objective To analysis the correlation factors which influence the prognosis and relationship of molecular subtypes on young patients.Methods Clinical data of 108 cases young breast cancer patients (≤ 35 years old) who were treat in the Third Affiliated Hospital of Zhengzhou University from January 2007 to October 2014 were retrospective analyzed.According to immunohistochemistry such as estrogen receptor (ER),progesterone receptor(PR),human epidermal growth factor receptor-2 (Her-2/neu),Ki-67 index,patients were divided into molecular subtypes and follow up.Results LuminalA subtype,LuminalB subtype,human epidermal growth factor receptor-2 overexpression subtype and basal-like accounted for 22％ (24/108),33％ (36/108),20％ (21/108) and 25％ (27/108) respectively,and there's 5-year disease-free survival rate were74.1％,62.8％,.56.8％,58.5％ respectively.Kaplan-Meier method was used to draw the disease-free survival curves through.There was no significant difference in the 5-year disease-free survival rate of each subtype (x2 =0.318,0.802,0.876,0.277,0.239,0.074,P＞0.05).Univariate analysis of prognostic factors of Log-rank showed that there were significant differences between recurrence with tumor size,age,lymph node metastasis and surgical methods in young patients with breast cancer(x2 =9.612,12.099,51.345,5.928,P＞0.05),while no significant difference with adjuvant chemotherapy,radiotherapy,endocrine therapy and molecular typing(x2 =2.381,1.958,0.027,2.612,P＞0.05).Multivariate Cox proportional hazards regression model analysis showed that tumor size (RR =5.487,95％ CI 1.519-19.822,P =0.009) and lymph node metastasis (RR =5.655,95％ CI 2.939 -10.884,P＜0.001) were independent risk factors for disease recurrence.Conclusion Tumor size and lymph node metastasis are important factors of prognosis on young patients.Young patients need the screening and therapy in the early time.
ABSTRACT
ObjectiveTo explore the expression of p130Cas and paxillin in breast carcinoma and investigate the relationships of p130Cas and paxillin levels with clinical and pathological characteristics.MethodsReverse transcriptase polymerase chain reaction (RT-PCR) was applied to detect the expression of p130Cas and paxillin in tumor tissues from 30 cases of primary breast carcinoma,15 cases of normal breast tissues and 10 cases of breast fibroadenoma.ResultsThe levels of p130Cas and paxillin were 0.444 ± 0.088,0.493 ± 0.073,0.739 ± 0.092,0.755 ± 0.137 in normal breast tissues and breast fibroadenoma tissues.The levels of p130Cas and paxillin were 0.914 ±0.186,0.303 ±0.043 in breast carcinoma tissues.Breast carcinoma tissues showed higher levels of p130Cas and lower levels of paxillin than normal breast tissues and breast fibroadenoma tissues(P ＜ 0.01 ).The expression of p130Cas was related with age (r =0.599,P =0.000 ),menopausal status (t =5.602,P =0.000 ),estrogen receptor ( ER ),progesterone receptor ( PR ) status (t =5.768,P =0.000; t =4.151,P =0.000 ) and histological grades (r =-0.668,P =0.000 ),but not related with tumor size (F =0.717,P =0.497 ),lymph node status (F =1.230,P =0.308 ) and pathological stages(r =0.283,P =0.137).The expression of paxillin was related with rumor size (F=4.114,P =0.028 ),pathological stages( r =-0.520,P =0.003),and lymph node status(F=12.418,P=0.000 ),but not related with age(r =0.294,P=0.115),menopausal status(t =-0.403,P =0.690),ER,PR status(t =0.749,P =0.460;t =0.006,P =0.995) and histological grades (r =-0.173,P =0.362).Conclusions p130Cas and paxillin have relations with the malignant transformation,invasion and metastasis of breast carcinoma.Measurement of p130Cas and paxillin may provide useful prognostic information for patients with primary or metastatic breast carcinoma.
ABSTRACT
Objective To explore the expression of p130Cas and c-erbB-2 in human breast carcinoma and the relationship between p130Cas and c-erbB-2 levels with clinical and pathological characteristics. Methods Immunohistochemistry SP staining was applied to detect the expression of p130Cas and c-erbB-2 in tumor tissues from 53 cases of human primary breast carcinoma,10 cases of breast fibroadenoma and in 10 cases of normal breast tissues. Results Breast carcinoma tissues showed higher levels of p130Cas and c-erbB-2 than normal and fibroadenoma tissues(both P＜0.01).The expression of p130Cas was related with age, menopausal status, ER, PR status and histological grades, but not related with tumor size, lymph node status and pathological stages. The expression of c-erbB-2 was related with ER status, histological grades and lymph node status, but not related with age, menopausal status, PR status, tumor size and pathological stages. There were no significant correlations between p130Cas and c-erbB-2. Conclusion p130Cas and c-erbB-2 have relations with the malignant transformation and differentiation of breast carcinoma.c-erbB-2 is associated with metastasis of breast carcinoma.p130Cas and c-erbB-2 can be served as useful indicators in the prognosis of breast carcinoma.
ABSTRACT
Objective To review the experience of surgical treatment of congenital esophageal atresia. Methods From 1987 to 2001, 32 patients with congenital esophageal atresia were treated surgically, 13 patients using the traditional method, 17 using the new method and 2 using esophago gastric reconstruction. Results There was no postoperative mortality in all patients. There was one anastomosis leak and 4 anastomosis stricture. No anastomosis leak and one esophageal stricture in the patients recieved new method. Conclusion The new surgical method for congenital esophageal atresia can effectively prevent postoperative anastomosis leak and stricture. One stage esophago gastric reconstruction can be used in type I and type II esophageal atresia and instead of two stage operation.
