My name is Greg. I have CLL. I took chemo treatments 3 years ago and was OK until this fall. The Dr. said my bone marrow is "70% packed". Is this an indication of what stage my cancer is at? I am looking into a bone marrow transplant.

Hello

Thanks for posting. Essentially with CLL your bone marrow will have a lot of CLL, and this does not change your stage. What will change your stage is the consequence of the bone marrow disease: anemia, thrombocitopenia, enlarged spleen and/or liver, etc.

There are two staging systems for CLL: Rai and Binet.

Rai staging System

Stage 0
Stage 0 chronic lymphocytic leukemia: absolute lymphocytosis (>15,000 per cubic millimeter) without adenopathy, hepatosplenomegaly, anemia, or thrombocytopenia.

Stage I
Stage I chronic lymphocytic leukemia: absolute lymphocytosis with lymphadenopathy without hepatosplenomegaly, anemia, or thrombocytopenia.

Stage II
Stage II chronic lymphocytic leukemia: absolute lymphocytosis with either hepatomegaly or splenomegaly, with or without lymphadenopathy.

Stage III
Stage III chronic lymphocytic leukemia: absolute lymphocytosis and anemia (hemoglobin <11 g/dL) with or without lymphadenopathy, hepatomegaly, or splenomegaly.

Stage IV
Stage IV chronic lymphocytic leukemia: absolute lymphocytosis and thrombocytopenia (<100,000 per cubic millimeter) with or without lymphadenopathy, hepatomegaly, splenomegaly, or anemia.

Binet classification

Clinical stage A: no anemia or thrombocytopenia and fewer than three areas of lymphoid involvement (Rai stages 0, I, and II)

Clinical stage B: no anemia or thrombocytopenia with three or more areas of lymphoid involvement (Rai stages I and II)*

Clinical stage C: anemia and/or thrombocytopenia regardless of the number of areas of lymphoid enlargement (Rai stages III and IV)
