title: [Blood triboluminescence in patients with cancer of the proximal stomach and esophagus].
abstract: Total triboluminescence, i.e. optic radiation induced as a result of mechanic activation of venous blood in a TPA-2 triboluminometer, was measured in patients with cancer of the gastric cardia and esophagus, and in healthy subjects. The parameter was assessed in control water samples, too. In the 252-649 nm range, five bands of emission were registered with peaks at 262, 280, 360, 422 and 649 nm subject to variation in certain segments of blood spectrum. Triboluminescence of the venous blood at 280 nm determines for the total triboluminescence registered in the entire spectrum. The triboluminescence of capillary blood at 302 and 418 nm calculated using K coefficient facilitates differentiating between inflammation and cancer. This express test takes less than 1 minute and requires a small blood sample (0.02 ml). The accuracy proved 88%.
