Abstract: This article extracted and analyzed several palm-print characteristics that correlate with the occurrence of gastric cancer and compared these characteristics with those of the control group by T-test. The results showed that there were differences between the patients and the control group in the ATD-angle, angle between the third flexor line and handbreadth, a-bRc of hand palms. These observations provide a powerful theoretical basis for establishing a quantifiable dermatoglyphics feature index system having relation with gastric cancer, and give a strong support for using clinical screening of early patients.
