Pathology Report Questions

Thank you for providing this service, it is a lifeline for many of us. Background: biopsy dx invasive ductal, Modified Bloom/Richardson 2/3. Mitotic activity infrequent, minimal tubule formation, er-/pr-/her2-, 1.3-1.0-1.4 cm by ultrasound. Tx A/C complete July 18th, Surgery Aug 15th bilateral mast. Pathology: The mastectomy was divided into two sections the first called: Lymph nodes, thoracodorsal nerve of right axilla, showed 3 nodes were taken all benign. The second section was referred to as: Right breast and axillary node, it showed
Small focus of residule invasive ductal carcinoma and DCIS measuring 0.4 cm in diameter, grade 3/3 Bloom Richardson, Nuclear Grade 3/3, prominent lymphoid reaction to tumour present,nearest resection margin (posterior) is clear. Sections confirm seven lymph nodes, on of these show the presence of a micrometastasis.

I am now being treated with taxotere for 4 rounds. I am 33 years old.

Questions:
1)What is a micrometastasis? Is it some cells, is it a small tumour? Can you tell by reading this report where the lymph node was located. Is there a chance that this metastasis is dead?

2)Is there any indication of vascular invasion?  

3)With the over all reduction in tumour size from 1.4 cm to 0.4 cm, would you consider this successful treatment?

Any other information would be appreciated. I am scared. Thank you for your time.

Dear Ctina:  1.  Micrometastasis means that there are cancer cells that are microscopic within the specimen - not generally a tumor.  Cannot tell from this report where the node was.  If there was micrometastasis, one would assume the cells were alive.

2.  Cannot tell from this report if there was vascular invasion.

3.  I would consider this successful treatment but as you are experiencing additional treatment was needed.

PS. Only one axillary node showed presence of a micrometastasis.
