Since gastric cancer possesses various malignant types, the levels of TRIP13 expression were studied in gastric tissues from 99 gastric cancer patients and established that TRIP13 expression status was significantly subjective to tumor-node-metastasis (TNM) staging and poor survival, suggesting that TRIP13 can be considered as an independent prognostic indicator for gastric cancer. The gene discussed is TRIP13; the disease is gastric cancer.
