What is Lymphoma ?
Lymphoma is a malignant transformation of lymphocytes (white blood cells)
Lymphocytes (B-cell and T-cell)involved in immune response to infection, transplanted organs or foreign bodiesThey are carried through lymphatic system as well as the blood, so lymphoma can start both in lymph nodes and spread anywhere throughout the bodyLymphoma can also start in ANY solid organ of the body- GI tract- skin- lung- heart- CNS- bones

Conclusions
1. Selected group of DLBCL patients may benefit from more aggressive treatment than standard R-CHOP chemotherapy
2. New agents are being evaluated for relapsed disease (conjugated monoclonal Abs and small molecule oral drugs) with promising results in early phase clinical trials
