Metastatic Sites

One of the most common cancers amongst women is breast cancer. The most common metastatic sites are the lymph nodes, lungs, liver, and bone. Metastatic spread to the urinary bladder is rare, and this case, as far as we are aware, is the first reported in the Caribbean. This patient developed urinary symptoms 4 years after her diagnosis of breast cancer. CT imaging showed thickening of the bladder wall, and histology confirmed metastatic breast cancer. As imaging modalities and cancer treatment improve, patients live longer with metastatic disease, and we will potentially see more unusual presentations of metastatic disease.

11517 Background: We analyses a mono institutional series of patients treated with metastatic breast cancer (MBC). Methods: From 2000 to 2006 forty consecutive patients affected by MBC were evaluated. The average age was 50 years (range: 30–79). All patients had HER2+ tumors (IHC 3+ or FISH+) and LVEF > 50%. Metastatic sites were: liver 18, lymph nodes 10, bone 9, skin 7, lung 5 pts. In 11 cases the sites of metastases were multiple (1–3). All patients were treated with Trastuzumab 4 mg/kg loading dose and 2 mg/kg weekly thereafter with weekly Paclitaxel 80 mg/m2 or weekly Vinorelbine 25 mg/m2; specifically, Paclitaxel was used in 26 patients and Vinorelbine in 14 patients. The endpoints were time to progression (TTP), duration of response, toxicity (including cardiologic) and overall survival. Results: A total of 1271 courses of weekly Trastuzumab were administered (average 28 courses per patient: range 8–72). There were 22 complete and partial responses (CR+PR=55%). In the association of Trastuzumab and Paclitaxel were seen :11 CR, 6 PR, 3 SD and 6 PD, (RR 65.3%). In the combination of Trastuzumab and Vinorelbine: 2 CR, 3 PR, 4 SD and 5 PD (RR 35.7%) . The most responsive sites were: liver 15 CR+PR (37.5%), lung 11 CR+PR (27.5%), lymph nodes 8 CR+PR (20%), and skin 6 CR+PR (15%). TTP was 7 months (2–27 months) and response duration 6.7 months (2–26 months). Overall survival at 5 years was estimated at 26.4 months. Toxicity rates were: hematological grade 4 in 2 pts, grade 3 in 3 pts, neurological grade 3 in 19 pts. No important cardiologic toxicity was observed: LVEF was reduced to 40% in 4 pts. Seven patients developed brain metastasis during therapy. The patients in PD continued Trastuzumab with other chemotherapy, no responses were observed. The median cost of treatment with Trastuzumab for patient was 16.147 € (range 3.987–39.959 €. Conclusions: Treatment with Trastuzumab plus chemotherapy has been shown to be effective and well-tolerated providing a good quality of life. The economic impact is important and is to define. The cost/benefit in this cohort of the patients is ongoing. No significant financial relationships to disclose.

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 the target of myb1-like 2, encoded by TOM1L2, was among the genes whose expression was most different in the brain and lymph node metastases of patients with metastatic breast cancer. TOM1L2 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of TOM1L2 in primary tumors was significantly correlated with patient overall survival in patients with breast cancer. Modulation of TOM1L2 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.

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.
