ABSTRACT
OBJECTIVES: We conducted a clinical risk factors analysis to define a prognostic model for high-grade primary gastric lymphoma (HG-PGL). METHODS AND RESULTS: The median event-free survival and overall survival of 214 HG-PGL patients were 54 and 104.5 months, respectively, after a median follow-up duration of 60 months. According to the prognostic factor analysis, survival, advanced age, male gender, higher LDH levels and the presence of ascites were identified as independent prognostic factors for HG-PGL. We identified four groups at different risk: group 1, no adverse effect; group 2, one factor; group 3, two factors; group 4, three or four factors. The new prognostic model showed excellent prognostic capacity to differentiate subgroups according to their risk stratification. CONCLUSIONS: The proposed new prognostic model for HG-PGL demonstrated a balanced distribution of patients into four groups with good prognostic capacity.
