Prognosis depends on the type of lymphoma, stage of disease, treatment, and comorbidities.
Worse prognosis is indicated by the following:[116]The International Non-Hodgkin's Lymphoma Prognostic Factors Project. A predictive model for aggressive non-Hodgkin's lymphoma. N Engl J Med. 1993 Sep 30;329(14):987-94.

B symptoms (fever, weight loss, night sweats)
Lymphadenopathy
Organomegaly
Extranodal involvement

Chemotherapy (e.g., R-CHOP) may be curative in a sizeable proportion of patients with aggressive lymphomas.[203]Couderc B, Dujols JP, Mokhtari F, et al. The management of adult aggressive non-Hodgkin's lymphomas. Crit Rev Oncol Hematol. 2000 Jul;35(1):33-48.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL)
