OBJECTIVE: To analyze the clinicopathological characteristics, treatment protocls and prognostic factors in patients with primary intestinal diffuse large B-cell lymphoma (DLBCL).
METHODS: The clinical data of 54 patients with DLBCL who were treated in Cancer Hospital of Chinese Academy of Medical Sciences in the period from August 2003 to November 2012 were retrospectively analyzed, and the relevant prognostic factors of DLBCL were analyzed.
RESULTS: Of the 54 patients, there were 43 males and 11 females (male∶female ratio was 3.91∶1), with a median age of onset of 49 (7-76) years. Most patients (64.8%) were in Lugano stage Ⅰ-Ⅱ. Of all the patients, 50 were followed up for a median of 49 (1-118) months. The 1-, 3- and 5-year overall survival (OS) rates were 82.0%, 69.9% and 60.7%, respectively; the 1-, 3- and 5-year progression-free survival (PFS) rates were 68.0%, 58.0% and 53.4%, respectively. Univariate analysis showed that the factors affecting prognosis of DLBCL patients included Lugano stage, B symptom, International Prognostic Index (IPI) score, lactate dehydrogenase level, β2-microglobulin level, tumor size, and treatment protocols (all P<0.05). The 5-year OS rate was 67.1% in the patients treated with surgery plus chemoradiotherapy, and 40.0% in those treated with surgery or chemotherapy alone (P<0.05). In the patients treated with chemotherapy combined with rituximab, the 5-year OS rate was higher than in those treated with chemotherapy alone (71.2% vs 47.6%, P<0.05). Multivariate analysis indicated that tumor size (RR=7.686, P=0.022) and lactate dehydrogenase level (RR=10.131, P=0.017) were independent prognostic risk factors affecting OS.
CONCLUSIONS: Primary intestinal DLBCL is a highly heterogeneous malignancy. Surgery combined with chemoradiotherapy and rituximab may help improve the overall prognosis of DLBCL patients.
