 This is an observational cohort registry study of at least 800 patients with suspected lymphoma in Malawi. The primary purpose of this study is to develop a large prospective longitudinal lymphoma cohort at Kamuzu Central Hospital KCH. Subjects with confirmed hematologic malignancies treated according to local standards of care will be actively followed for 2 years after diagnosis to assess clinical outcomes. After 2 years, if subjects are well, they will be discharged from clinic if they desire and contacted via telephone every 6 months for 5 years after lymphoma diagnosis simply to assess vital status. Subjects who wish to continue clinic follow-up after 2 years will be seen every 6 months until 5 years after lymphoma diagnosis. Those who are unwell after 2 years and continuing to receive active treatment will continue follow-up in clinic with all treatment details recorded.
