Abstract Purpose: In breast cancer, the lymph node status is of prognostic importance and a decisive factor in therapy planning. This study shows the distribution of lymph nodes metastases of node-positive breast cancer patients. Risk factors for lymph node metastases are described.Methods: 2095 patients with primary breast cancer were analyzed. Analysis included descriptive analysis (median, standard deviation, ranges) and statistical analysis (Chi², discriminant analysis).Results: The nodal stage was positive in 39.4% of all patients and negative in 60.6%. If the nodal stage was positive, only 1 lymph node was involved in 36% of the patients; more than 1 lymph node was involved in 64% of the patients. With an increasing number of lymph node metastases in level I, the probability of an involvement in level III also increases (F 437.845, p = .000). Other indicators are evidence of hemangiosis (F 247.728, p = .000) or lymphangiosis (F 167.368, P = .000). Despite <10 affected lymph nodes, 3.4% of the patients had nodal stage N3 due to level III involvement.Conclusion: Even with only a small number of lymph node metastases in level I higher lymphatic stations are often affected. The data cannot lead to a decision regarding an operation or radiation indication, but they can better substantiate the risk for certain therapy decisions.

Node Metastases

The protein product of the ras cellular oncogene(s) (p21) was assayed in primary breast carcinomas from two groups of patients who had different axillary lymph node status. Using an immunohistochemical assay, the intensity and percent of neoplastic cells demonstrating ras p21 antigen staining were significantly higher in the primary tumors from patients with lymph nodes positive (LN+) for malignancy (20 patients) compared with the lymph node negative (LNO) group (21 patients). The expression of p21 also correlated with tumor size. Age and estrogen receptor status did not influence p21 staining. The antigen expression of p21 was similar in intensity and distribution in the primary tumor and regional lymph node metastases. Enhanced expression of p21 in primary breast cancers that metastasize to regional nodes indicates that ras p21 may be a determinant of the malignant potential of breast cancer cells and may represent a new class of more biologically relevant tumor markers.

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.

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 teashirt zinc finger homeobox 3, TSHZ3, 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. Analysis of a separate microarray dataset revealed that TSHZ3 was also differentially expressed in brain metastatic tissues. TSHZ3 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of TSHZ3 in primary tumors of the breast was correlated with patient post-progression survival, in lymph node positive patients but not in lymph node negative patients. Modulation of TSHZ3 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.
