Further observation of Kashara isoenzyme in patients with malignant diseases

The Kasahara isoenzyme of alkaline phosphatase was found in cancer tissues from patients with gastric carcinoma, maxillary carcinoma, pulmonary carcinoma, and carcinoma of the urinary bladder, in addition to hepatoma. This fact suggests that the Kasahara isoenzyme may not be a specific marker protein of liver cancer but could occur in a variety of neoplasms.
