The overall survival (OS) rates were 67.9% and 36.2% at 2 and 3 years, respectively, in the metachronous first group; 73.8% and 73.8%, respectively, in the metachronous second group; and 68.1% and 56.7%, respectively, in the synchronous tumor group. There was no difference in the survival rate among the 3 groups before 2 years, but after 2 years, a shorter OS rate was observed in the metachronous first group than in the metachronous second group and synchronous tumor group. For all patients, age &gt;60 years, male sex, and \u2a7e3 involved nodal sites were considered independent prognostic factors associated with survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>OS time was shorter in patients with NHL who developed a second tumor than in those who were diagnosed with solid cancer synchronously and second neoplasm after previous solid tumors.
