Hi there!
1. It is difficult to comment on the diagnosis without knowing the relevant clinical details. It would be best to discuss this with the treating doctors.
2. Death does not occur due to elevated WBC count, the elevated counts are just an indication of an underlying disease process such as an infection/ sepsis, inflammation, cancer etc.
3. A hyperacute rise to 40,000 predominantly of neutrophils is more likely to be due to conditions such as sepsis than cancer (Assuming this was not the only WBC count that was done).
4. Though very unfortunate, conditions such as this can arise. Looking at the tests he/ she appears to have developed renal compromise as well and possible liver damage, which could have been a compounding factor.
Take care!
