Laboratory studies of mice and human cells found that a protein called Metastasis suppressor 1 (Mtss1) is downregulated in hematopoietic and progenitor cells when chronic myeloid leukemia is present. Mtss1 levels are restored when complete remission is achieved, suggesting the pathway might represent a new therapeutic target.
The FDA granted approval to ofatumumab for the treatment of patients with recurrent or progressive chronic lymphocytic leukemia who are in complete or partial remission after two or more lines of prior therapy.
A laboratory study showed that peroxisome proliferator-activated receptor gamma agonists such as pioglitazone could help treat chronic myeloid leukemia patients who are resistant or otherwise unresponsive to treatment with tyrosine kinase inhibitors.
Dr. Brian Link discusses clinical implications of the large Mayo Clinic/ University of Iowa study (ASCO abstract 8504) showing patient symptoms rather than scheduled surveillance imaging drove detection of relapses in patients with diffuse large B-cell lymphoma (DLBCL).
