Aj. Karayiannakis et al., Serum levels of tumor necrosis factor-alpha and nutritional status in pancreatic cancer patients, ANTICANC R, 21(2B), 2001, pp. 1355-1358
Background:Tumour necrosis factor alpha (TNF-alpha) is a multifunctional cy
tokine associated with cancer-related cachexia. In this study we evaluated
serum levels of TNF-alpha in pancreatic cancer patients and investigated th
eir relationship;Ds:to cachexia. Patients and Methods: Serum TNF-alpha leve
ls were determined in 63 patients with pancreatic cancer wing an enzyme imm
unoassay specific for human TNF-alpha. Results: Serum TNF-alpha levels were
detected in 36.5% of patients. Patients with metastatic disease showed sig
nificantly higher positive serum TNF-alpha rate compared to those with non-
metastatic disease. Patients with detectable serum TNF-alpha levels had sig
nificantly lower body weight and body mass index, lower haematocrit and hae
moglobin values, and lower serum fetal protein and albumin levels compared
to those with undetectable TNF-alpha levels. Serum TNF-alpha levels were in
versely correlated with body weight, body mass index, haematoclit, haemoglo
bin, and serum protein and albumin levels. Conclusions: TNF-alpha levels ar
e detectable in the serum of pancreatic cancer patients, particularly in th
ose with advanced disease, and these levels correlate with poor nutritional
status.
