CD3 ε and ζ expression on PBMC from patients with colorectal carcinoma measured by flow cytometry

The mean fluorescence intensity (MFI) of staining for ε and ζ on a CD3⁺ population is shown. Blood was taken from patients with colorectal carcinoma prior to surgery. The Dukes stage of disease is noted for each patient; two patients (*) had inoperable tumours and were estimated as Dukes stage C. The total lymphocyte count (TLC expressed as cells × 10⁹/l) for the colorectal carcinoma patients was within the normal range.
