To Study the Role of Liquid Based Cytology (LBC) for Diagnosis and Characterization of Biliopancreatic Tumor s Compared With Standard Cytology and On-site Evaluation.

Not Applicable

• Conditions: Pancreatobiliary-Type Carcinoma

• Registration Number: NCT04022408
• Lead Sponsor: Institute of Liver and Biliary Sciences, India

Brief Summary

Liquid Based Cytology is a method of preparing samples for examination in cytopathology.Liquid-based cytology (LBC), enables cells to be suspended in a monolayer. LBC makes better cytological assessment possible with improved sensitivity and specificity, since fixation is better and nuclear details are well preserved in the technique. Conventional cytology is gold standard for biliopancreatic malignancy examination. This method is operator depended and have high inter observer variation . On site evaluation increases the sensitivity of conventional cytology but requires the presence of pathologist at the time of sampling . Our study will compare LBC with conventional cytology ,If found to be non inferior will be great help in centre were on site evaluation cannot be carried out . It will further reduce the interobserver variation
