THURSDAY, June 12, 2014 (HealthDay News) -- Low cholesterol
levels may increase kidney cancer patients' risk of death, a new
The findings indicate that cholesterol testing may help guide
treatment for kidney cancer patients, the study authors said.
They analyzed cholesterol levels in 867 kidney cancer patients
before they had surgery for their cancer and followed them for a
median of 52 months after surgery. Low cholesterol levels before
surgery were associated with more advanced cancer and greater
cancer spread after surgery.
The investigators also found that patients with high cholesterol
levels were 43 percent less likely to die after surgery than those
with low cholesterol levels, and that assessing cholesterol levels
improved the accuracy of patients' prognoses.
While the study found an association between low cholesterol
levels and a raised death risk among kidney cancer patients, it did
not prove a conclusive link between the two.
It's not clear how cholesterol levels may affect kidney cancer
patients' chances of survival, but certain components of
cholesterol may influence tumor growth and spread, according to the
authors of the study published June 12 in the journal
"As this was a hypothesis-generating study, our findings should be confirmed in [future research]. If confirmed, patients with low cholesterol may be considered high-risk and may be treated or followed up more aggressively," Dr. Tobias Klatte, of the Medical University of Vienna in Austria, said in a journal news release.
