Clinical analysis of Primary Gastrointestinal Non-Hodgkin's Lymphoma

To study the clinical characteristics and prognostic factors of survival for patients with primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL).

A retrospective analysis was performed for 104 PGI-NHL patients who were admitted in Baoding First Central Hospital from July 2003 to January 2014.

There were 58 males and 46 females. The median age of onset was 53 (15-83) years old. In terms of pathogenic sites, there were 51 gastric cases (49.00%) and 53 intestinal cases (51.00%), with the median survival of 35 (1-130) months. The 1-, 3- and 5-year overall survival (OS) rates were 88.40%, 80.70% and 78.80%, respectively. The factors influencing the progression-free survival (PFS) and OS rates were studied by univariate and multivariate analyses. The PFS and OS rates of patients with B-cell PGI-NHL were significantly higher than those of patients with T-cell PGI-NHL (P<0.05). The PFS and OS rates of patients with primary gastric lymphoma were significantly higher than those of patients with primary intestinal lymphoma (P<0.05), but the data were not associated with Ann Arbor stage or LDH level (P>0.05). Compared with non-surgical patients, only patients with intestinal lymphoma benefited from surgery (P<0.05).

The pathogenic site and pathological type are risk factors that affect the survival of PGI-NHL patients, and chemotherapy should be given the first priority for patients with primary gastric lymphoma.
