The doctor has a hard time explaining these tumor marker test results. Can you?

Hello doctor,

I was just curious what your translation of this might be. I am copying this information directly from a printout of medical records which I can upload if necessary. This is the tumor marker test results of a 70 year old white male.

Reports from three years ago:

• CEA 1.4 ng/mL
• AFP-tumor marker 26164.3 ng/mL

Reports from yesterday:

• BUN 13 mg/dL.
• Creat 0.90 mg/dL.
• CA 9.3 mg/dL.
• TP 7.9 g/dL.
• Alb 3.4 g/dL - Low
• Alk Phos 66 U/L
• AST (SGOT) 39 U/L
• ALT (SGPT) 33 U/L
• Total Bili 0.5 mg/dL
• Gap 5 --- LOW
• Est GFR >60 mL/min
• AA-GFR >60 mL/min
• BUN/Creat Ratio 14.4
• Osmo,Calc 274 mOsm/kg
• Glob 4.5 g/dL
• AFP Tumor Marker 18.9 ng/mL - high 
• HCV RNA IU/mL Pending
• HCV RNA log IU/mL Pending

Thank you.

Thank you doctor,

The doctors told him he had multiple cancers and hepatitis after the earlier tests and told him to get his affairs together and move into a hospice to die. He then started a home treatment of something called 'The Budwig Diet' which is a combination of flaxseed oil and cottage cheese. Then he got the results yesterday (which I also attached previously). What do yesterday's results show? Why would his doctor have a hard time explaining the results? They are saying they need more time to investigate and have even sent a nurse to the health food store where he gets 'The Budwig Diet' from, to ask questions about what he was being given. I guess what I am asking is, are the new results showing a considerable improvement or decline, or possibly a medical device malfunction or needing calibration? I am really just grasping at straws, and wondering if you have seen something like this before.
