Some chronic lymphocytic leukemia (CLL) patients may wonder how they can check to see if treatment is working. Watch as Dr. Nadia Khan from Fox Chase Cancer Center answers a viewer’s question and provides insights on what tests are used in assessing response to CLL treatment.
Dr. Khan, here’s a question that I think many are probably thinking of right now, what tests do you give patients to see if CLL treatment is working?
Dr. Nadia Khan:
Thank you, Jessica. During the course of CLL treatment and at the end of a time-limited treatment course, we’re assessing for responses, so as a patient is going through their treatment, we may decide to re-image to determine if there has been debulking of lymph nodes. And depending on the treatment that we’re administering and where the lymph nodes are located, we may decide to do imaging sooner or later, so for example, if there are palpable lymph nodes while a patient is on therapy, and we can measure these readily by physical exam in the clinic, we may not feel as compelled to re-image at an early time point, if there is valiantly or in large seen that is hard to palpate. And we want to understand if treatment is working after approximately three to four cycles of therapy, we would assess for a good response to treatment if clinically, it also does appear that patients are responding, and if there was any question as to respond, we would image at an earlier time point when patients are being treated with a venetoclax-based (Venclexta) regimen and there is significant adenopathy or an enlarged spleen, we may reassess the size of lymph nodes and spleen during the course of venetoclax ramp-up to determine if patients can be transitioned from inpatient to outpatient ramp-up.
