Core Tip

Core Tip: Through retrospective analysis of 83 patients with gastric signet ring cell carcinoma (SRCC) and paraffin-embedded sections from 83 patients were stained with Alcian blue (AB), periodic acid Schiff (PAS), Ki67, protein 53, and human epidermal growth factor receptor 2, we confirmed that AB to PAS (A/P) ratio > 0.5 is a potential risk factor for the prognosis and low PAS expression is an independent risk factor for the prognosis of gastric SRCC. PAS expression and A/P ratio could help in predicting the clinical prognosis of SRCC patients. However, our study had a limited sample size this and further follow-up studies are still needed.
