      • Abstract

      Primary pulmonary non-Hodgkin’s lymphoma(NHL) is very rare, and although the prognosis is favorable, clinical features, beneficial diagnostic procedures, prognostic factors and optimal management have not been clearly defined.

      In this study, thirty-eight cases of primary pulmonary NHL treated in Shanghai Chest Hospital during a 10-year period were retrospectively reviewed, and clinicopathological features and prognosis were analyzed.

      There were twenty-eight patients with mucosa-associated lymphoid tissue (MALT) lymphoma, three with diffuse large B-cell lymphoma, one with peripheral T-cell lymphoma, one with mantle cell lymphoma and five with unclassified B-cell lymphoma. The cohort consisted of 21 male and 17 female patients with a median age of 57.5 years. At presentation, 36.8% of patients were asymptomatic, and unilateral tumors occurred more frequently than bilateral and predominantly in the right lung. Thirty-three patients underwent surgical resection single or combination chemotherapy, and five patients received combination chemotherapy alone. Overall survival(OS) was significantly longer in patients with MALT lymphoma than that of non-MALT lymphoma (129.9 vs. 71.5 months, P = 0.019 by log-rank test). Patients who had received surgical resection had a better OS (126 vs. 65.4 months, P = 0.036 by log-rank test). Additionally, multivariate analysis showed that elevated serum lactate dehydrogenase (LDH) level was independently associated with a poor OS (P = 0.048).

      Primary pulmonary NHL has atypical clinical manifestations and non-specific imaging changes. Surgical resection is vital in clarifying the diagnosis and obtaining a favorable prognosis. Serum LDH level was an independent prognostic factor.
