[Relation of spontaneous chemiluminescence, electrochemiluminescence and resistance of blood serum in patients with cancer of the proximal part of the stomach and esophagus].

The levels of spontaneous chemoluminescence of serum in patients with cancer of the proximal part of the stomach and the esophagus were found to be 2-6 times the age-connected norm. The said concentrations decreased by half following radiation treatment, to rise by 75% after surgery. At later periods after surgery, chemoluminescence levels dropped almost to normal unless complications developed. However, in patients with gastroesophageal cancer, the level of spontaneous chemoluminescence remained high over a long period of time. Variation patterns were identical, with an amplitude being significantly lower. Changes in blood serum resistance were insignificant. Scale factor K varied in the range of 6-66. In cases of purulent complications, spontaneous chemoluminescence levels showed a sharp rise, the values of K exceeding 75. This pattern made it easier to differentiate between inflammatory lesions and neoplasia.
