The following parameters were evaluated on univariate analysis by the chi-square (chi2) statistic for their correlation to disease progression or death from any cause. N: total number of patients; PD: progressive disease; p-val: p-value; D: death of any cause; PS: performance status; ECOG: Eastern Cooperative Oncology Group; MSK: Memorial Sloan-Kettering Cancer Center; IESLG: international extranodal lymphoma study group; LDH: serum lactate dehydrogenase; GC: germinal center type histology; non GC: non germinal center type histology; PET2–: negative PET2 result; PET2+: positive PET2 result.
