How Does Leukeran Affect Cancer Cells?

Chlorambucil is a nitrogen mustard alkylating agent that interferes with DNA replication and promotes apoptosis in susceptible cells. Its cytotoxic activity affects rapidly dividing malignant cells as well as normal bone marrow cells.

Who Is Treated With Leukeran?

Leukeran is used for chronic lymphocytic leukemia and selected malignant lymphomas under current labeling. Blood counts are followed closely during therapy due to the risk of severe bone marrow suppression.

How Is Leukeran Dosed?

The usual oral dose is 0.1 mg to 0.2 mg per kg daily for three to six weeks, commonly about 4 mg to 10 mg per day in an average adult. Hodgkin disease commonly uses 0.2 mg per kg daily, while other lymphomas or chronic lymphocytic leukemia commonly use 0.1 mg per kg daily. Doses are adjusted according to blood counts and clinical response.

What Serious Risks Are Linked to Leukeran?

Leukeran carries a boxed warning for severe bone marrow suppression and states that chlorambucil is carcinogenic, probably mutagenic and teratogenic, and produces human infertility. Other serious concerns include secondary malignancies, seizures, severe skin reactions, and fetal harm.
