Sigrid Skånland’s project group Functional precision medicine for hematologic cancers

Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in Europe and it remains incurable. Targeted therapies have made a breakthrough in the treatment of CLL over the last decade. However, many patients develop resistance, have severe side effects or relapse during treatment. To prevent ineffective treatment and toxic effects, there is an unmet clinical need for tailoring optimal therapy for each patient.

Our research group focuses on developing functional precision medicine for B-cell malignancies, in particular CLL. By performing functional analyses such as drug sensitivity screening and single cell signaling analyses directly on the patients' cancer cells, our aim is to identify biomarker signatures that can predict treatment outcomes for the individual patient, and thus guide treatment decisions.
