[Abstract]:Research objective breast cancer is a disease which endangering women's health. The incidence of the disease is the first of the female malignant tumor, and it is rising rapidly. As a hormone related tumor, endocrine therapy is a routine method for the treatment of breast cancer system. It is an accurate assessment of the expression of estrogen receptor, ER protein in breast cancer. The bed treatment scheme and prognosis are very important. The breast cancer treatment guide is to determine the expression of ER protein and the expression of progesterone receptor (progesterone receptor, PR) protein. The Ki67 index and HER-2 detection should be included in the routine examination of invasive breast cancer. This study should use tissue chip technique to compare the infiltration of ER in progressing stage. The differences and characteristics of the expression of the primary breast cancer and the axillary lymph node metastases in the same period, analyze the homogeneity and stability of ER protein in the progression of lymph node metastasis of breast cancer, and enrich the understanding of the ER expression of breast cancer (especially the ER expression in the metastatic foci). The retrospective study method is used to collect the pathology department of Shaoxing People's Hospital 20. 100 paraffin specimens of primary female invasive ductal carcinoma with axillary lymph node metastases were found in 100 cases. All cases had complete clinical data. The surgical operation was modified radical mastectomy, and preoperative radiotherapy and chemotherapy were not accepted. 5 typical loci were selected in the primary tumor specimens in each case. The axillary lymph nodes were labeled with all visual transfer sites under the microscope to prepare a "full information tissue chip". The expression of ER protein was detected by immunohistochemistry (IHC), and the characteristics and stability of the expression were analyzed. According to the number and intensity of ER stained cells, ER (0): no staining or 10% infiltrative cancer cells showed weak nuclear staining. Color; (1+): the infiltrating cancer cells of 10%-30% showed weak nuclear staining; (2+): more than 30% of infiltrating cancer cells showed moderate intensity of nuclear staining; (3+): more than 50% of infiltrating cancer cells showed strong nuclear staining. Results 100 cases of invasive ductal carcinoma, 472 of the 500 sites of primary focus. Only one site in the primary focus was ER+. The expression of ER positive rate 53%.ER protein in the primary focus of this group was ER+: all 222 effective loci of the primary foci in 47 cases were negative, and 192 effective sites in 41 primary foci were ER diffuse 3+ expression; the other 12 cases had 58 effective sites, ER expression intensity was not consistent, ER expression 3+, 2+, 1+, and 0 were 26 (44.8%) respectively. 13 (22.4%), 7 (12.1%) and 12 (20.7%).100 cases of axillary lymph node metastases were effective in 626. Only one loci ER+ in the metastatic lymph node was located as the metastatic lymph node ER+ in the patient. The ER positive rate of 54%.ER protein expression in the lymph node metastasis of this group: 249 of the 249 metastatic lymph nodes in 46 cases were negative, and 33 cases 177. The effective loci of the metastatic lymph nodes were all ER diffuse 3+ expression, and the other 21 cases with 200 effective sites were dissimilar in ER expression, ER expressed 3+, 2+, 1+, and 0, respectively, 77 (38.5%), 15 (7.5%), 9 (4.5%), and 99 (49.5%). By comparing the expression of ER protein in the primary and the same phase of the axillary lymph node metastasis, ER3+ at all sites in the primary foci. Of the 41 cases expressed, 234 (86%) lymph node metastases were expressed in ER3+, ER expression 2+, 1+, and 0 metastatic foci were 10 (3.7%), 4 (1.5%) and 24 (8.8%). According to case analysis, ER positive expression was found in the metastatic lymph nodes in 39 cases (95.1%), and all lymph nodes in all lymph nodes were expressed as 3+, and the remaining lymph nodes were negative expression in the remaining cases. In 47 cases with negative expression of ER, 298 (96.1%) lymph node metastasis ER negative expression, ER expression 1+, 2+ and 3+ metastasis location points were 3 (1%), 3 (1%) and 6 (1.9%). 40 cases of lymph node metastasis loci (224) were negative expression, ER expression in all 4 lymph node metastases of 1 cases were diffuse one. 3+; in the other 6 effective loci of 82 metastatic foci, 74 (90.2%) loci were negative, ER expressed 1+, 2+ and 3+ were 3 (3.7%), 3 (3.7%) and 2 (2.4%). In 12 cases of primary focal site ER, a total of 44 axillary lymph node metastasis loci were obtained. Among them, metastatic lymph nodes were ER negative and metastasis lymph nodes were metastatic. ER expressed 3+, and 17 metastatic lymph nodes in the other 4 cases expressed 3+, 2+, 1+, and 0, respectively, 9 (52.9%), 2 (11.8%), 2 (11.8%) and 4 (23.5%). The total consistency of primary and lymph node metastases was 87%. stratified analysis. Among the primary foci of ER positive expression, the corresponding lymph node metastases were expressed in ER positive and remaining in the remaining cases. The expression of ER was negative in all metastatic foci, and the positive rate of positive expression of ER in primary and metastatic foci was 88.7%. Of the 41 cases with positive ER 3+ positive expression in the primary foci, 39 cases of corresponding lymph node metastasis were ER positive, the rate of agreement was 95.1%. In 47 cases of ER full Yin at all sites of primary foci, 40 cases of corresponding lymph node metastases were negative and 7 lymph nodes were transferred. The positive expression of ER was 85.1%, and the negative expression of ER in primary and metastatic foci was 85.1%. In 12 cases of primary foci, but the intensity was not consistent (3+, 2+, 1 +), 8 cases had ER positive metastatic lymph nodes, the coincidence rate was 66.7%. conclusion 1. The expression of ER egg white in invasive ductal carcinoma of the mammary gland was in the primary tumor and axillary lymph node metastases at the same time. The consistency between the primary foci and the same 3+ expression in the primary ER was higher. The consistency of the lymph nodes with the primary foci was higher.2. The tissue chip technology was used to sample the primary tumor and the axillary lymph node metastases at the same time. The expression of the ER protein in the tumor was fully reflected, and the expression of the tumor was.3, and ER was carried out in the tissue chip specimen. Immunohistochemical staining showed that the expression pattern of 3+ was negative or.4 negative. The positive rate of ER in this group was slightly lower, which might be related to lymph node metastasis.
