Background:Oesophageal cancer is the eighth most common cancer and sixth in cancer
related mortality, worldwide. The current study was carried out to see the role of three
markers (P53, HER2, EGFR) in various oesophageal lesions, their association in cancer
progression and their role as tumour markers.
Materials and Methods: Study was conducted on 100 cases of oesophageal lesions
consisting of both neoplastic and non-neoplastic spectrum. Immunohistochemistry was
performed on all the specimens for three markers as per the set criteria and expression
of these markers was studied and scoring was done accordingly.
Results: Present study was conducted on 100 cases with oesophageal lesions both
neoplastic and non-neoplastic. Parameters like age, gender, family history, alcohol
intake, cigarette smoking and location of lesion in oesophagus were also studied.
Expression of P53, Her2, EGFR were studied using IHC.
Conclusion: P53, HER2 and EGFR show a strong association with EC and
premalignant lesions, the absence of their expression in normal oesophageal tissue and
non-neoplastic conditions, points out their role in development of EC and tumour
progression. Out of the three markers, P53 has the strongest association with EC. HER2
overexpression was more in case of EAC than ESCC, indicating its importance in
guiding further treatment. EGFR over- expression was noted in fewer cases.
