The Binet staging system is a widely used staging system for chronic lymphatic leukemia (CLL). The use of staging systems is recommended in recent CLL guidelines in order to help to guide therapy. Patients are grouped prognostically based on physical examination and blood counts. The Binet clinical staging system comprises three stages, which takes into consideration five potential sites of involvement: cervical, axillary, and inguinal lymph nodes, spleen and liver.
|Stage||Hb [g/l]||Platelets [G/l]||LN, spleen, liver|
|A||> 100||> 100||< 3 involved regions|
|B||> 100||> 100||> 3 involved regions|
|C||< 100||< 100|
