[Diagnostic value of oscillopolarography of earlobe blood for stomach cancer].
This paper reports the results of oscillopolarographic assay of earlobe blood in 212 patients examined by fibergastroscopy. Polarographic value above 0.081 was regarded as positive. The positive rate was 96.7% in 30 patients with gastric cancer and 100% in 10 with cancer of cardia and 1 with esophageal cancer. The false positive rate was 14.0% in 171 patients with gastric and duodenal diseases. All 72 healthy persons gave the value of less than 0.081. This method, being convenient and requiring only a small amount blood, is acceptable. It has a high positive rate for stomach cancer, and could be helpful in screening for some malignant tumors.
