Abstract
ABSTRACT:
BACKGROUND:
Gastric carcinoma is the fifth most common cancer worldwide. P53 is tumor suppressor gene, located on chromosome 17p13.1, involved in cell senescence and differentiation. In gastric cancer, P53 expression had shown to be associated with bad prognosis.
AIMS OF THE STUDY:
To determine P53 immunohistochemical expression in gastric adenocarcinoma and correlate it with clinic-pathological variables.
MATERIALS AND METHODS:
Forty formalin fixed, paraffin embedded tissue blocks (24 endoscopic biopsies & 16 gastrectomy cases) included in this retrospective study, collected from archived materials from Baghdad hospitals & laboratories (from January 2019 to December 2020).
Two sections of 5μm thickness were done, one stained with H&E and the other for P53 using mouse monoclonal antibody (clone BP-53-12).
RESULTS:
Immunohistochemical expression of P53 was expressed in 32 cases (80%) (24 cases intestinal type adenocarcinoma & 8 cases diffuse type adenocarcinoma). Five had score +1, eleven had score +2 and sixteen had score +3. Twelve lymph nodes positively expressed p53, eleven of them (91.7 %) involved by metastatasis.
CONCLUSION:
P53 significantly expressed in intestinal type adenocarcinoma and directly related with tumor differentiation, depth of invasion and lymph node metastasis but not with tumor location.
