I recently underwent a bilateral mastectomy after finding a tumor in my right breast. The pathology of that tumor is below:
2 lymph nodes tested: negative.
BRCA1 & BRCA2 tests: negative.
Tumor size: 1.5cm
Tumor focality: Single focus of invasive carcinoma
Skin: doesn't invade into dermis or epidermis
Nipple and DCIS: DCIS doesn't involve the nipple epidermis
DCIS: DCIS is present and positive for EIC
DCIS dimensions: 2cm
Architectural patterns of DCIS: Solid
Nuclear grade of DCIS: Grade 2
Necrosis of DCIS: not identified
Lobular Carcinoma: Absent
Type of invasive carcinoma: Invasive ductal carcinoma (NOS)
Margins of DCIS: margins uninvolved by DCIS
Location closest margin: superior radial margin
Distance from closest margin: 2mm
Margins - Invasive: margins uninvolved by carcinoma
Location closest margin: superior radial margin
Distance from closest margin: 1mm
pTNM staging: pT1c, pN0, pM0.
Prognostic markers performed prior to case: Yes, S13-40089
Estrogen Receptor: 86%
Progesterone Receptor: 67%
Her-2/neu score: 0
Oncotype score: 11
My oncologist said that he doesn't pay attention to the Oncotype score because it's tests were done on 83% post-menopausal women, and since I'm pre-menopausal it didn't apply to me. I was a bit discouraged at this. He, even with the low Onco score, said he felt I needed chemo (seemed "bent" on chemo). I'm a bit concerned about this and hoped you could provide some feedback.
