Primary gastric lymphoma of T-cell origin: Clinicopathologic features and treatment outcome

We conducted a retrospective analysis to investigate the natural history and the clinical outcome after treatment of primary gastric lymphoma of T-cell origin. Seventeen cases of T-cell origin among 444 primary gastric lymphoma patients were analyzed. The median age of the 14 male and 3 female patients was 49 years (range 22–76 years). The median progression-free survival (PFS) and overall survival (OS) were only 10 months (95% CI; 0–20 months), and 12 months (95% CI; 4–21 months), respectively. This study showed that the incidence of this subtype of T-cell gastric lymphoma was very rare, and had poor prognosis.
