Screening of esophageal and gastric cancer by occult blood bead detector

A previously described bead method used to detect blood is simple, cheap, and effective; it can be repeated periodically. In 11 provinces in China, 233,825 persons (age range, 30–70 years) were screened. A positive occult blood test result was found in 28,557 persons (12%). Of these, 16,918 underwen...

Description
Summary:A previously described bead method used to detect blood is simple, cheap, and effective; it can be repeated periodically. In 11 provinces in China, 233,825 persons (age range, 30–70 years) were screened. A positive occult blood test result was found in 28,557 persons (12%). Of these, 16,918 underwent a gastroscopy, resulting in the detection of 581 cancers that were located in similar frequencies in the esophagus, gastric cardia, and gastric body; 70% of the lesions were in an early or moderately advanced stage. Among 119 patients with early‐stage cancer, the 3‐year survival rate was 98.3%. After preliminary screening of cancer, the 4‐year follow‐up found a mortality rate in the group with negative occult blood test results that was only 25% of that of the positive group. Preliminary yearly screening would detect more early cancers and fewer advanced cancers. The mortality rate of esophageal and gastric cancer might be reduced drastically. Cancer 1993; 71:216‐8.
