Also, Bertolini et al. (1999) studied patients with NHL (mainly DLBCL and FL but also other types of lymphomas such as MCL, PTCL, ALCL, large granular NK-cell lymphoma, and extranodal marginal zone lymphoma of MALT), whose leptin levels were not only similar regardless of the outcome but were also not correlated with age, gender, or even-free survival [213]. This evidence concerns the gene LEP and diffuse large B-cell lymphoma.
