High-Risk Chronic Lymphocytic Leukemia<\/h2>\n
\n

Jeff Sharman, MD:<\/strong> Hello, my name is Jeff Sharman. I\u2019m the Medical Director of Hematology Research for US Oncology, and I am a practicing oncologist at the Willamette Valley Cancer in Eugene, Oregon.<\/p>\n

Today I\u2019ve been asked to present a case of a 79-year-old gentleman with relapsed chronic lymphocytic leukemia to address some of the treatment considerations we have in this patient population.<\/p>\n

This particular patient is a hypothetical patient but referred to me. We\u2019ll say that he was a 79-year-old gentleman who initially presented to his outside medical oncologist for the first time complaining of some vague intermittent abdominal pain and progressive fatigue. His past medical history is notable primarily for medically-controlled hypertension. He had a myocardial infarction 8 years ago and is on low-dose aspirin. His original CLL diagnosis was about 7 years ago, and after a period of watchful waiting, he had progressive lymphocytosis and adenopathy. He was treated with ibrutinib 420 mg daily, his symptoms improved, and he achieved a stable disease with resolution of lymphadenopathy.<\/p>\n

Unfortunately, after 5 years of disease control on ibrutinib, he complained of increasing fatigue and decreasing appetite. Upon physical exam, he had a return of palpable lymphadenopathy, and his spleen was palpable, 4 centimeters below the costal margin. At that time, seen by an outside medical oncologist, he was started on rituximab monotherapy due to his medical comorbidities, but after 6 months on this regimen, he presents to my clinic after moving to be closer to family.<\/p>\n

His physical exam was notable this time for palpable bilateral cervical adenopathy, right-sided inguinal adenopathy. Labs showed a white blood cell count of 55,000, predominately lymphocytes, and neutrophil count of 3100. He was anemic and thrombocytopenic, with a hemoglobin of 9.4 and platelets of 90,000, respectively. His beta-2 microglobulin was elevated, and, notably, he had a creatine clearance of just 31 mL per min.<\/p>\n

Flow cytometry confirmed the typical immunophenotype for CLL, and at this time, FISH testing was performed and, importantly, returned a deletion of 17p in a high fraction of the cells. He was Rai stage 4 with an ECOG performance status of 1. At this time, treatment was initiated with idelalisib in combination with rituximab, or I should say idelalisib was added to rituximab at this time, 150 mg PO BID.<\/p>\n

Now this is an interesting case, and it presents a number of features that are challenging in terms of how to pick therapy in this population with significant comorbidities. I\u2019ve been asked to address questions pertaining to both his prior management, his current situation, and so forth.<\/p>\n

The first question I\u2019ve been asked is to describe my initial impression of the case and what the prognosis was for this patient. You know this is a patient who has high-risk CLL. He has relapsed after ibrutinib, and he has a deletion of 17p. What that means is that chemoimmunotherapy is not going to work for this individual, so you really don\u2019t have that much in the way of options. Then you\u2019ve exhausted BTK inhibitors, and there\u2019s a question of what you have left.<\/p>\n

In this particular case, the outside provider used rituximab monotherapy probably for lack of clarity in what options might have been available; this is a patient that because of his age and comorbidities, it\u2019s very possible this patient may ultimately pass away of their CLL, which, in contemporary CLL management, seems like a relatively rare occurrence.<\/p>\n

When we discuss risk stratification for patients with chronic lymphocytic leukemia, there\u2019s a couple of things that are really important. We think about their IgHV status, which is really a measurement of how quickly the CLL is growing. What are the kinetics of growth? Then we think about the FISH status, which is how resistant it is to therapy. Deletion of 17p is a particularly noteworthy abnormality because patients with 17p have very brief responses to chemoimmunotherapy-based approaches.<\/p>\n

Similarly, we\u2019re seeing updates with targeted therapy, such as venetoclax, that 17p can retain adverse prognostic significance in this population. In this particular patient\u2019s case, idelalisib had been added to the regimen. It\u2019s noteworthy that idelalisib outcomes appear to be independent of 17p, so whether 17p is present or not, the outcomes relative to 17p don\u2019t matter quite as much.<\/p>\n
