Further treatment after surgery?

My mother just got his breast removed. The surgical pathology reports says as follows:

Diagnosis: Left breast:
1. Infiltrating ductal carcinoma grade II on a scale of I to III according to modified Bloom and Richardson grading system.
2. Size of lesion: 3.5 x 2.5 x 1.5 cm.
3. Lesion is 0.2 cm from deep margin.
4. A small focus of lymphatic invasion is present which is 0.1 cm from deep margin.
5. Nipple and areola: Tumour free.
6. Total 08 lymph nodes are recovered, out of which 03 are positive for metastatic disease.
- size of largest metastatic deposit in the lymph node measeures 1.1 x 1 cm.
- No perinodal extension is present.

We just went to two of the best Oncologist of the city for advise regarding further treatments!

Advise of first one:
He recommended to start radiotherapy immediately and asked for following reports:
- E.R. / P.R.
- HER2
- Ki-67

He further said that on the basis of the above three reports he will decide whether chemotherapy is required or not. He told us about a possible combination of the results of the above reports that was i think as follows:

- E.R /  P.R & HER2.. one of them must be negative and the other one positive, i did not exactly remember which one he told to be negative;
- Ki-67 must be below 15;

If the result would be as above then chemotherapy would not be required and radiotherapy would be sufficient.


Second Oncologist:
He told us to start chemotherapy immediately and asked for the same reports as the first one did. But he said that chemotherapy and radiotherapy both are required irrespective of the results of the test.


Please advise regarding the point of view of first oncologist and what should be done in the above case.
