Despite the sufficient amount of data accumulated in the literature, there are still no factors, on the basis of which it would be possible to estimate the regional lymph nodes status in breast cancer with a high degree of accuracy. The review presents literature data relating to the influence of clinicopathological, molecular-biological and genetic characteristics of primary tumor on lymph node metastases. Data of 66 foreign and Russian articles are included.

Objective: to identify molecular genetic predictors of metastatic spread to regional lymph nodes in patients with breast cancer (BC) based on the analysis of gene expression profile of the primary tumor.Materials and methods. The study included 358 patients with BC who underwent surgical treatment in breast cancer department of Academician V.I. Kulakov Research Center of Obstetrics, Gynecology, and Perinatology, Ministry of Health of Russia. Among all included into the study patients, 132 (36.9 %) had metastases in at least one axillary lymph node. Molecular genetic examination of the tumor tissue was carried out using reverse transcription polymerase chain reaction; the diagnostic panel consisted of 45 functional and 3 reference genes. Results. Patients with metastases to regional lymph nodes were generally younger (p = 0.006), had larger primary tumor (p<0.001) and higher total malignancy score (p<0.001). The groups were also significantly different in tumor location (p = 0.005). Comparative analysis of transcriptome tumor profiling revealed statistically significant differences between groups in the level of expression of three genes: TMEM45A (p = 0.016), CCND1 (p = 0.019), and MIA (p = 0.046). Based on the data obtained we used mathematical modeling and created a predictive model, which with a high degree of probability (AUC = 0.791) allowed to predict the presence of regional lymph nodes metastases in patients with BC.Conclusion. TMEM45A, CCND1 and MIA gene expression in the primary tumor were the markers of lymph node involvement in BC. The developed predictive genetic signature can become an additional diagnostic tool to predict the risk of lymph node metastases at the point of planning the volume of axillary surgery in patients with BC.

Introduction: The aim of this study was to determine the serum levels of malondialdehyde (MDA) in patients with invasive breast cancer in relation to its serum levels in patients with benign breast disease, and to investigate correlation between MDA serum levels with pathohistological prognostic factors (tumor size, lymph node involvement, and histologic grade [HG]), estrogen receptor (ER) status, and with breast cancer patient’s age and menopausal status. Methods: A total of 43 with well-documented invasive breast cancer were included in this study: 27 with positive axillary’s lymph nodes, and 16 with negative axillary’s lymph nodes, and 39 patients with findings of benign breast diseases. MDA determination in serum of breast cancer and benign breast disease patients was performed by the fluorimetric method, immunohistochemical staining was performed for ER, and routine pathohistological examination was conducted for pathohistological factors. Results: MDA serum levels in breast cancer patients were significantly higher than MDA serum levels in benign breast disease patients (p = 0.042). No statistically significant difference between MDA serum levels in breast cancer patients with and without lymph node metastases was found (p = 0.238). No statistically significant correlations between MDA serum levels and tumor size (p = 0.256), HG (p = 0.124), or number of positive lymph nodes (0.113) were found. A statistically significant correlation between serum MDA levels and ages of breast cancer patients with lymph node metastases was found (p = 0.006). Conclusion: Obtained results support the importance of MDA in the carcinogenesis of breast cancer. According to our findings, serum level of MDA could not be a useful prognostic factor in breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that collagen type XVI alpha 1 chain, COL16A1, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. COL16A1 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of COL16A1 in primary tumors of the breast was correlated with patient overall survival, in lymph node negative patients but not in lymph node positive patients. Modulation of COL16A1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that diaphanous homolog 2, encoded by DIAPH2, was among the genes whose expression was most different in the brain and lymph node metastases of patients with metastatic breast cancer. DIAPH2 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of DIAPH2 in primary tumors was significantly correlated with patient recurrence-free survival in patients with breast cancer. Modulation of DIAPH2 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain while evading immune clearance in the lymph nodes in humans with metastatic breast cancer. These data are one piece of evidence suggesting a common ancestor or tumor clone for brain and lymph node metastases that originate from the primary tumor, alluding to patterns in developmental origin and migratory pathways through the lymph node in human brain metastatic breast cancer.
