Understanding ROR1

ROR1, an oncogene recently discovered on chronic lymphocytic leukemia (CLL) B cells, is being studied by researchers as a potential target for CLL treatment. Dr. Brian Koffman met with Dr. Thomas Kipps, who is researching ROR1, at the 2014 American Society of Clinical Oncology (ASCO) meeting to discuss this oncogene and its potential use in treating CLL.

Prolonged lymphocytosis during Ibrutinib therapy

The Bruton’s tyrosine kinase (BTK) inhibitor ibrutinib has outstanding activity in patients with chronic lymphocytic leukemia. Most patients experience lymphocytosis, representing lymphocyte egress from nodal compartments.

This resolves within 8 months in the majority of patients, but a subgroup has lymphocytosis lasting >12 months. Here we report a detailed characterization of patients with persistent lymphocytosis during ibrutinib therapy. Signaling evaluation showed that while BTK is inhibited, downstream mediators of B-cell receptor (BCR) signaling are activated in persistent lymphocytes. These cells cannot be stimulated through the BCR and do not show evidence of target gene activation.

Progression-free survival is not inferior for patients with prolonged lymphocytosis vs those with traditional responses. Thus, prolonged lymphocytosis is common following ibrutinib treatment, likely represents the persistence of a quiescent clone, and does not predict a subgroup of patients likely to relapse early.

Developmental Protein Plays a Role in Spread of Cancer


Dr. Thomas Kipps and scientists from his research laboratory at the UC San Diego Moores Cancer Center discover an association between a protein called ROR1 and EMT, a process that occurs during embryogenesis.

Stopping cancer’s spread: New protein found to control deadly cancer metastasis

Researchers have found a critical element that may explain why some cancers spread farther and faster than others, a discovery that could lead to one of the Holy Grails of cancer treatment: containing the disease.

Scientists from the University of California, San Diego School of Medicine, Dr. Thomas J. Kipps and colleagues,  have identified a protein that seems to serve as a switch, regulating the spread of cancer from the primary tumor to distant spots in the body – a process known as metastasis.  The protein is used by embryo cells during early development, but then disappears from the body after an individual comes out of the womb.

Ibrutinib, a potential breakthrough in treating chronic lymphocytic leukemia (CLL)

(TIME.com) — It’s called ibrutinib, and it’s a potential breakthrough in treating chronic lymphocytic leukemia (CLL) that could leave patients with fewer side effects than chemotherapy.

4/6/2013 Fighting Cancer at the UC San Diego Moores Cancer Center

In an article published in the San Diego Union Tribune,  assistant project scientist, Emanuela Ghia, PhD, is highlighted at the Moores UC San Diego Cancer Center fight against cancer in association with the American Cancer Society.  While this article focuses on breast cancer research, it highlights some of the important advances, applications, and techniques that we are applying in our fight against CLL and other blood cancers.

Study senior investigator Thomas J. Kipps, MD, PhD, is Evelyn and Edwin Tasch Chair in Cancer Research and professor of medicine in the Division of Hematology-Oncology. He is Interim Director of the UC San Diego Moores Cancer Center, where he co-leads the Hematologic Malignancies Program.

Dr. Kipps is principal investigator of the UC San Diego site in the Cancer Immunotherapy Trials Network, a research network established last year by the National Cancer Institute and headquartered at the Fred Hutchinson Cancer Research Center in Seattle.

Dr. Kipps was named to the National “Top Doctors” List for 2011-2012. In both 2010 and 2011, he was selected for the “San Diego Top Doctors” list.
