Node Metastases

Supraclavicular lymph node metastases appeared in a female patient six years after thyroidectomy, radioiodine therapy and external radiation for a follicular thyroid carcinoma and four years after mastectomy and lymphadenectomy for an invasive ductal breast cancer. It was not possible either by conventional imaging methods or by serological methods, to assign the metastases to one of the two primary tumors. Anti-CEA immunoscintigraphy and SPECT of the cervicothoracic region showed a circumscribed pathological uptake of 99mTc-labeled anti-CEA antibodies in the area of the supraclavicular lymph nodes. The preoperative suspicion of lymph-node infiltration by CEA-expressing breast cancer cells was confirmed histologically after surgical removal of the lymph nodes.

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.

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 EvC ciliary complex subunit 1, EVC, 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. EVC mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of EVC in primary tumors of the breast was correlated with patient overall survival, in lymph node positive patients but not in lymph node negative patients. Modulation of EVC 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.
