No tumor residue (multiple samples) was found in your mother's root resection, which is a good phenomenon, indicating that your mother is sensitive to chemotherapy.

But your mother's immunohistochemistry is not very good.

Estrogen er and progesterone pr are negative, not hormone-dependent breast cancer. Endocrine therapy is not effective, and your mother doesn't need endocrine therapy.

C-erbB is the expression level of oncogene. The higher the expression rate (the more+signs), the worse the prognosis (the higher the recurrence and metastasis rate, but not absolute), and the highest CerbB-2 is++.

Gene P53 is negative, which is better, indicating that cancer cells are not aggressive.

Ki-67 is related to the prognosis of breast cancer patients, especially those with negative lymph node metastasis, and is helpful to determine whether to use adjuvant chemotherapy. Ki-67 is not very active.

The doctor said that it is necessary to detect a data index of HER2, so as to further detect whether CerbB-2 is a few plus signs (+) by in-situ hybridization. If CerbB-2 is++,the probability of recurrence and metastasis is higher. If the family economic conditions are good, targeted therapy (Herceptin) can be carried out, but the price is relatively high, about 300,000 yuan is needed. On the other hand, using this drug does not mean that 100% is effective. For example, CerbB-2++, Herceptin is not very effective. Do HER2 data indicators, cancer hospitals generally do, you can ask. If the family's economic conditions are not good, there is no need to do it.

According to the results of immunohistochemistry and the situation during operation, we can make a follow-up treatment plan and let your mother's attending doctor get the plan.

It is also recommended to do chemotherapy twice as soon as possible. If ER and PR are negative, postoperative chemotherapy must be grasped.

Adjuvant Chinese medicine treatment after chemotherapy can increase immunity and prevent recurrence.

I wish your mother a speedy recovery!
