Blood & Cancer

Treatments for chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL) have advanced in recent years, with more new developments on the horizon. James Gerson, MD, of the University of Pennsylvania, Philadelphia, reviewed some of these advances and future directions while describing how he would treat three patients. Host David H. Henry, MD, posed the following cases for consideration. Case 1 In a 75-year-old male with no comorbid illness, routine blood work revealed a WBC count of 15,000/mcL. The manual differential showed mature lymphocytes and smudge cells. The patient has no constitutional symptoms, but there is suspicion of CLL. What to do? An incidental finding of elevated WBC is the most common presentation for CLL, Dr. Gerson noted. Flow cytometry is how most diagnoses are made. If the patient’s blood sample is CD5+ and CD20+, in the vast majority of cases, the patient has CLL. The main alternative diagnosis is MCL, so Dr. Gerson recommends checking for cyclin-D1 overexpression and transloca
