Of patients, 553 (7%) 767 (9.7%) 779 (9.9%) 625 (55.15%) thyroid, 209 (2.6% ) 87.4% Rh (+), 12.6% them (-). 38% A 5.2% (-), 13.8% B 2.2% 7.7% AB 1.3% 28% 0 3.8% With group distribution all cancers; When gastric, cancers compared, no statistically significant difference found. However, it found that (+) higher colorectal compared other cancers. Conclusions: In type. addition, type practice.
