Abstract
An apparent increase of blood group antigen A was noted during a study of 21 patients with carcinoma of the colon associated with either leukemia or lymphoma. Thirteen of 20 patients typed were blood type A. This incidence was then compared to that of the blood group A antigen in the normal population of the city of New York, the blood donor group of Columbia-Presbyterian Medical Center, patients with carcinoma of the colon alone, and patients with leukemia and lymphoma alone. Occurrence of blood type A in patients with these two neoplasms was found to be higher than in the normal population and also higher than in the colon carcinoma group. Eighteen of the 21 patients had the lymphocytic form of chronic leukemia or lymphosarcoma.
