Would you operate on a 85 yr man with chf ,for tumor w/cancer in sigmoid colon, 80 pd weight loss,bad ekg too,worried he won't make it, what chance?

Here are 2 options: Surgery can be done on 85 year olds depending on their cardio-pulmonary reserve. If his heart failure is well controlled and his Ejection fraction is > 40% then surgery may be safe. Alternatively, Primary chemotherapy can shrink localized Colon cancer. Go seek a consultation with a medical oncologist. You may need 2 opinions from medical oncologists and select one who has used chemo in old patient

Complicated Question: There's not enough space in this forum to answer a complex question like this. There are many nuances... how bad is the CHF? (ie, What is the NYHA Stage? What is the EF?) How large / problematic is the cancer? What type of cancer? (adenocarcinoma,? squamous?) What is the Grade and Stage of the cancer? (They're not the same thing). Hopefully a surgical oncologist is helping guide the pt. I feel 4u.
