Using flow cytometry, we evaluated peripheral blood leucocyte subsets in 84 patients with primary and secondary liver cancer. The patients had significantly lower absolute (659+/-386 vs. 906+/-360 cells per microl, p=0.004) numbers of CD3+ CD4+, relative (9+/-5 vs. 12+/-4%, p=0.02) and absolute (154+/-115 vs. 221+/-83 cells per microl, p=0.02) numbers of CD8+ CD28+, absolute numbers of CD3+ and relative and absolute numbers of CD19+. Relative and absolute numbers of CD3+ DR+, CD3+ CD69+ and CD14+ CD16+ cells were significantly elevated in patients compared to controls. The phenotype was similar in 54 patients exposed to chemotherapy compared to 30 untreated patients. Urinary neopterin, a marker of systemic immune activation, was significantly higher in patients with liver tumours compared to controls. A negative correlation was observed between urinary neopterin and the absolute numbers of CD3+ CD4+ (Spearman rank correlation coefficient, rs = -0.54, p<0.0025) and CD19+ (rs = -0.49, p<0.01) in untreated patients. We conclude that, independently of prior chemotherapy, patients with liver present with markedly decreased numbers of CD3+ CD4+ lymphocytes as well as with other abnormalities of peripheral blood leukocyte phenotype. Similar to patients with human immunodeficiency virus infection, the decrease in CD3+ CD4+ lymphocytes is associated with systemic immune activation.
