Serum total sialic acid and regan isoenzyme levels in patients with lung cancer.
Serum total sialic acid (TSA), Regan isoenzyme (RI) (heat stable placenta like alkaline phosphatase) and TSA/Total protein (TP) ratio were estimated in 44 cases of Lung cancer using highly specific chemical methods to assess their efficacy as malignancy markers. Levels of the two markers were compared with 27 matched healthy controls. A significant increase (P less than 0.001) in both the bio-markers were compared with 27 matched healthy controls. A significant increase (P less than 0.001) in both the bio-markers was observed compared to controls. TSA/TP ratio was significantly higher (P less than 0.001) in lung cancer patients compared to controls. TSA levels were elevated in more cases of patients compared to elevations in RI. Mean values of TSA and RI were higher in epidermoid carcinoma than adeno carcinoma. The use of combination of these markers may be considered in the diagnosis of the disease in future trials.
