Perry and colleagues identified the following significant differences in the epidemiology of NHL in developing countries, compared with the developed countries [7] :

  • Higher percentage of males
  • Lower median age at diagnosis for both low- and high-grade B-cell lymphoma
  • Lower frequency of B-cell lymphoma and a higher frequency of T- and NK-cell lymphoma
  • Approximately 20% more cases of high-grade B-cell lymphoma and 10% fewer cases of low-grade B-cell lymphoma
