Writing about a newly diagnosed, pre-treatment Stage IV Lung Cancer patient (most likely NSCLC, biopsi to confirm soon). He lost some weight quickly a couple of months ago and then was able to stop the loss. He is frail with a BMI < 18. Now again he seems to be loosing weight. We are wondering if the tumor is becoming more active?
1- Are there any drugs that can help slow the cachexia while we wait for biopsi results and a possible treatment plan? I've seen a couple of small studies on effectiveness of ATP. Is this used in clinical practice?
2- Are there Lung Cancer specific nutrition guidelines in terms of how much extra calories are needed and mix of Protein vs.Carbs and fat? His current diet is over 60% carbs, about 20% Protein. I saw one study suggesting increase of Proteins might be beneficial.
3- what regular blood tests does he need to keep track of his nutrition status. I'm guessing Albumin, pre-Albumin?
