Dear MSK Colleagues, Earlier today I accepted the resignation of José Baselga, MD, PhD, as Physician in Chief. His letter of resignation is here, and I believe it speaks for itself. It is effective immediately. Dr. Baselga has made numerous contributions to our organization, our patients, and the field of cancer treatment and research. We are grateful for his service. Lisa DeAngelis MD, currently the Chair of Neurology, will become the acting Physician in Chief while a search for Dr.Baselga’s successor is conducted. Dr. DeAngelis is a leader in the field of neuro-oncology and is held in high esteem by her colleagues throughout MSK. We are thankful for her willingness to take on this challenging role. Questions about Dr. Baselga’s disclosures and relationships with outside organizations have caused concern from the community, our staff, and most importantly our patients and family members. As you know, MSK has robust programs in place to manage how our staff should work with outside organizations and we are confident of strong compliance in this area. We will remain diligent. There will be continued discussion and review of these matters in the coming weeks. Everyone at MSK is united around the commitment to deliver the highest quality care. Our first obligation is to our patients and their wellbeing throughout treatment. In this we have never wavered. Regards, Craig Thompson President and CEO
