Father is 80 years of age, and was diagnosed with:
"Invasive ductal carcinomo, nottingham grade 2. Focally extends to lateral margins of resection. Microscopic focus of intraductal carcinoma with microcalcification is noted. Immunostains for estrogen and progesterone receptors are positive. Immunostain for HER2/neu is negative (1+membranous staining. Tumor measures 2 cm in greatest dimension in the submitted material."
He is diabetic (oral meds). Had a coronary about 18 years ago; can't recall meds for blood pressure and beta-blocker. Severe arthritis in neck, back, knees; working through various pain-management options, with little success. No feeling in feet and hands, and little fine-motor control; difficulty eating. Welbutrin is prescribed for depression. Aricept has helped slow memory loss. Not active, other than "scooter" outside. Can still care for himself. I don't have full accounting of prescription meds, but they are tedious for him.
Am concerned that he will not tolerate chemo treatments, and perhaps not radiation. My research indicates that chemo is the norm, augmented with endocrine therapy.
My question concerns the advisability of endocrine therapy only, vs. devastating effects of chemo. His quality of life, now, is such that he is barely mobile; I'm afraid the chemo will de-mobilize him, and depression will take further toll. I've been unable to determine if it is possible to declare this particular cancer agressive or non-agressive or re-gressive, based upon method of treatment. Can you advise?
