Abstract

Introduction: Phosphatase and tensin homologue (PTEN) is an important tumour suppressor in multi-step tumorigenesis. To establish the role of PTEN in gastric cancer progression, we examined the PTEN expression degree in gastric cancer tissues. We also explained the connection between PTEN expression and histopathological findings. Materials and methods: Our study was cross-sectional and made up of 50 patients with known gastric cancer. Immunohistochemical staining for PTEN was done on gastric cancer tissues. Tumour behaviour was estimated by histopathological assessments. Results: Twenty-seven (54%) of the 50 patients had PTEN staining. The evaluation of the connection between PTEN expression and demographic data and tumour behaviours revealed no meaningful relationship between PTEN expression and patients’ age, gender, tumour site and size, tumour type, tumour grade and stage, neural, and lymphovascular invasion (P-value > 0.05). Conclusion: PTEN expression level is expected to be a significant molecular event in the progression of gastric cancer and may be a predictive marker for gastric cancer behaviours dependent on society. © 2023 Sociedad Espanola de Anatomia Patologica
