Hello, I understand that you wish simple treatment for your father due to his advanced age. However, oral medicines are given only for some symptom relief and they will not cure the disease. Also, to exactly comment the treatment required, I need to see all the reports. If at all, your family does not wish for treatment due to poor health, oral chemotherapy (metronomic chemotherapy) can be given. I need to see the reports and know his weight, height to prescribe.
