Introduction: Malignancies of lymphoid cells can be divided into Hodgkin and non-Hodgkin lymphomas (NHL) on the basis of pathologic features, clinical manifestations and treatment. In this paper we present data on lymphomas in Golestan province, in the northeast of Iran, during 2004-2006, using three years results of the Golestan population-based cancer registry (GPCR), a voting member of the International Association of Cancer Registries (IACR).
Methods: GPCR started collecting data on all cancers from all public and private diagnostic and therapeutic centers (hospitals, specialist physicians' offices, pathology, laboratory, and imaging centers) of Golestan province in 2004.
