We examined the association between primary disease site and survival in MCL patients to identify subgroups with distinct characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p>We analyzed the United States Surveillance, Epidemiology and End Results Program database for MCL cases reported from 2000 through 2009.

The most common extranodal primary sites were of the gastrointestinal (GI) tract (7.8%), the head and neck (6.2%), and the hematologic\/reticuloendothelial systems (3.6%). Asians\/Pacific Islanders were more likely than whites or blacks to have GI tract or head and neck disease (<jats:italic>P<\/jats:italic> &lt; .0001 and <jats:italic>P<\/jats:italic> = .002, respectively). Advanced disease and B symptoms were less common in those with primary disease of the GI tract or head and neck than in those with primary disease of the lymph nodes (both <jats:italic>P<\/jats:italic> &lt; .0001). In a multivariate Cox regression model, patients with primary disease of the GI tract and head and neck had superior survival compared to those with primary disease of the lymph nodes; hazard ratios 0.75 (95% CI = 0.62\u20100.90) and 0.68 (95% CI = 0.55\u20100.85), respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>Primary site of disease may be an important prognostic factor for patients with MCL.
