title: The clinical and pathological features of patients with hematological neoplasms: a study of hospital-based Cancer Registry from western Turkey.
abstract: OBJECTIVE
  To evaluate the frequency and the main features of patients with hematological neoplasms (HNs) who were diagnosed between 1992-2005 at the Izmir Ataturk Education and Research Hospital (IAEAH), affiliated with Izmir Cancer Registry (ICR) database.
  
  
  METHODS
  A total of 2,424 HNs were recorded with reference to ICD-0-3 according to Surveillance, Epidemiology, and End Results (SEER) data among 20,895 recorded cancer patients from 1993 to 2005. The percentages of male and female patients were 58.5% and 41.5%, respectively. The age ranges were as follows: 15-44 years (37.3%), 45-64 (36%), and > 64 (26.6%). One thousand and nineteen (56%) patients had B cell and 108 (5.9%) patients had T/NK (natural killer) cell lymphoid neoplasms. One hundred and ninety-four (10.7%) patients had lymphoblastic leukemia, 267 (14.7%) had Hodgkin's lymphoma (HL), and 603 (24.9%) had myeloid leukemia. Three hundred and five (16.7%) patients had extranodal involvement (in 1821 regions). The major extranodal location was the stomach.
  
  
  CONCLUSIONS
  It seems that our data make a contribution to the relevant literature, because the epidemiologic data of Turkey are inadequate, and hematopoietic neoplasms have different geographic distribution.
