RESUMO
PNS are uncommon manifestations of cancer. The current literature about these syndromes in the setting of cHL is disintegrated. A systematic literature review of all published literature was conducted. One hundred twenty-eight patients from 115 publications met the inclusion/exclusion criteria. Eight-five patients were of the NS subtype (66.4%). The most frequent clinical presentation of the PNS was CNS manifestation (25.8%). The majority of patients were diagnosed with the cHL and PNS simultaneously (42.2%). In 33.6% of patients, the lymphoma diagnosis preceded the PNS diagnosis. In 16.4% of patients, the PNS diagnosis preceded the lymphoma diagnosis. The presence of PNS antibodies was reported in 35 patients (27.3%). Age older than 18 was associated with higher prevalence of PNS. The CR rate of the lymphoma was 77.3%. The complete resolution rate of the PNS was 54.7%. Relapse of lymphoma was reported in 13 patients, and recurrence of the PNS upon relapse was reported in 10/13 patients.
