My wife is going under chemotherapy after mastectomy of her left breast (On 26/12/2015). Cancer was T2N2G2, ER/PR negative & HER2 positive. 3 weekly ECx4 & weekly Taxol + Trastuzumab has been completed. Now doctor advice for 25 days Radiotherapy & 3 weekly maintenance Trastuzumab for next 9 months.
Due to some personal problem, I want to take Radiotherapy in a Government hospital near my native place. Doctors of this govt. hospital has given me advice that one cycle of maintenance Trastuzumab should be postponed & taken only after when Radiotherapy completes.They stated its reason that both treatments are cardio-toxin & should not be clubbed during RT because RT will be given to left side chest & some radiation may be taken by heart also. Please advice in this matter.
They proposes this RT by Linear Accelerator but I have little knowledge about this process & anxious about its side effects.
Also Please let me know about consequences of delaying RT by one week and delaying maintenance Trastudumab by one cycle. Whether it will be safe?
Although, I will discuss it with my Medical Oncologist also but I want that you please guide me in this matter.
