Comparison of a new tumour marker, CA 19-9, with alpha-fetoprotein and carcinoembryonic antigen in patients with upper gastrointestinal diseases.

Background: Fibreoptic endoscopy is a highly efficient diagnostic tool, which is now increasingly being used in the diagnosis of upper gastrointestinal diseases. This study has been carried out to evaluate the distribution of various upper gastrointestinal diseases based on endoscopic findings in a tertiary care hospital in Mysore.Methods: A cross-sectional study was conducted based on data from endoscopic register of 1000 subjects who underwent endoscopy for various upper gastrointestinal symptoms from 1st January 2017 to 31st December 2017(one year).Results: Mean age of the study population was 50.23 years (SD-15.46). Minimum age was 12 years and maximum was 88 years. About 44.7% of the study subjects belonged to 40-60 age group.61.6% of the study subjects were males. Most common indication was pain abdomen (32.1%) followed by dysphagia (22.2%). Of the 1000 study subjects 18.6% had normal findings. Most common finding was Gastritis / Duodenitis /Gastric erosions (28%). Malignant lesions were noted among 11.1%, of which esophagus and stomach are 5.4% and 4.9% respectively.Conclusions: Endoscopic diagnosis is useful for early detection of UGI diseases and helpful for their management.

Objectives We calculated upper 95% reference limits for serum alpha-fetoprotein (AFP)and carcinoembryonic antigen (CEA) according to the CLSI/NCCLS C28-A3 guideline. Material and methods Serum samples from 1400 healthy male subjects were collected from the Fangchenggang Area Male Health and Examination Survey (FAMHES). Serum AFP and CEA values were measured by electrochemiluminescence immunoassay on COBAS 6000 system E601 (Elecsys module) immunoassay analyzers. Results Serum AFP and CEA values were not normally distributed but log normally distributed. The upper 95% reference limits of the reference intervals were ≤4.76 IU/mL (nonparametric) or ≤4.56 IU/mL (parametric) for AFP and ≤5.57 ng/mL (nonparametric) or ≤5.82 ng/mL (parametric) for CEA. The distribution of AFP levels was found to be consistent between the non-smoking and smoking (p=0.740) and non-drinking and drinking groups (p=0.698). The distribution of serum CEA levels was significantly higher in the smoking than the non-smoking group (p<105), whereas there was no significant difference in this respect between the non-drinking and drinking groups (p=0.147). A significant increase with age was found both for serum AFP and CEA levels, and the age-dependent reference intervals were calculated. Conclusions The reference intervals for serum AFP and CEA show a slight deviation compared to previously reported reference levels. Distinct reference intervals of serum CEA must be established for smoking and non-smoking populations. In addition, age-dependent reference intervals should be implemented in clinical laboratories.
