[Proteinase inhibitors as markers of stomach cancer]

The study was concerned with assay of alpha 1.2-microglobulins (MGs) and pregnancy-associated alpha 1.2-glucoproteins (PAGs) which are considered nonspecific markers. The study group included 52 patients with gastric precancer and 40 patients with gastric tumors. A correlation was established between MG levels and carcinogenesis which may be interpreted as an indicator of malignant transformation of chronic ulcer or metastasis development following radical surgery for stomach cancer.
