Serum leucine aminopeptidase profile in cancers of gastro-intestinal tract with special reference to hepatic metastasis.
Serum leucine aminopeptidase (LAP) was estimated in 30 cases of gastro-intestinal cancers, and compared with 50 age and sex matched controls. Highly significant increase of serum LAP was seen in 7 patients with hepatic metastasis (p less than 0.001) from adenocarcinoma of stomach, colon and rectum. The enzyme values showed a highly significant increase in carcinoma of colon, when compared with different anatomical sites of the gastro-intestinal tract (p less than 0.001). However, in adenocarcinoma of stomach and rectum, significantly increased level of serum LAP was observed (p less than 0.01) which contrasted sharply with the normal enzyme values in squamous cell carcinoma of oesophagus and anal canal.
