In this, the seventh part (originally held July 26, 2011) of our eight-part online, integrated educational course, Drs Stephanie A Gregory and John P Leonard discuss recent advances in the treatment of non-Hodgkin lymphoma/chronic lymphocytic leukemia. (Webinar)
TARGET AUDIENCE
This activity is intended for hematologists, medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of non-Hodgkin lymphoma.
OVERVIEW OF ACTIVITY
Hematologic cancer includes the lymphomas, the leukemias, multiple myeloma and other related disorders such as myelodysplastic syndromes and myeloproliferative diseases, all stemming from lymphoid and myeloid progenitor cell lines. Cytotoxic chemotherapies, autologous and/or allogeneic hematopoietic stem cell transplant and biologic or molecular-targeted therapies have been the focus of treatment algorithms designed to assist clinicians in the clinical care of patients with hematologic cancer. Despite the existence of such tools, many areas of controversy persist within the academic and community settings, especially within the area of non-Hodgkin lymphoma. The recent entry of novel agents and the emergence of extensive practice-changing clinical trial data have created clinical scenarios in which multiple treatment options may be available but the optimal strategy is highly debatable. To bridge the gap between research and patient care, this CME activity will use a review of recent ASCO papers and other relevant publications, faculty case presentations, Q&A and discussion of community practice patterns to assist practicing clinicians in the formulation of up-to-date and appropriate treatment strategies.

1. Rituximab (R) maintenance in mantle-cell lymphoma (MCL)
Since the PRIMA study in follicular lymphoma (FL) was first presented at ASCO 2010 demonstrating improved progression-free survival with two years of maintenance R, this strategy has become well established in FL. However, a lack of data led to lingering doubt/skepticism about its effectiveness in MCL. At the June European Hematology Association meeting in London this began to change as a trial for patients with MCL over age 60 demonstrated that R maintenance following R/chemo induction resulted in a median remission duration of 51 months compared to 24 months with low-dose maintenance interferon. Interestingly, the current ECOG trial evaluating induction bortezomib/bendamustine/R in MCL provides another sign that maintenance may be taking hold as all patients continue R for two years.
2. Promising agents and novel strategies
During our broadcast John presented a 66-year-old patient with MCL and disease progression after multiple prior regimens, including R-CHOP and BR. With a rapidly deteriorating performance status, the patient chose to enter a Phase I trial of the Bruton’s tyrosine kinase inhibitor PCI-32765, and John showed a stunning set of CT scans demonstrating a major response in this woman. Stephanie then mentioned other small molecules in development with apparent efficacy and tolerability in B-cell neoplasia, including CAL-101, and both faculty noted ongoing trials evaluating proteasome inhibitors (bortezomib) and IMiDs (lenalidomide).
3. “Watch and worry” versus R induction and maintenance
John commented on data presented in June at the International Conference on Malignant Lymphoma in Lugano evaluating quality of life for patients on the landmark UK trial first presented at ASH demonstrating a 33% three-year PFS rate with observation compared to an 81% PFS rate with R induction and maintenance for two years. Quality of life trial data are often difficult for clinicians to apply in their practices, but these new findings are interesting in that the untreated group actually experienced an improved quality of life with time but patients who received R demonstrated an additional incremental benefit. The faculty speculated that in this and other cancers, after the initial life-shock of diagnosis begins to subside, many patients feel more at ease over time, and in this psychological milieu of adapting to life with a treatable but not curable illness, patients seem to feel even better when receiving a relatively nontoxic treatment that slows disease progression.
4. CLL
John presented a 75-year-old man with CLL and a trisomy 12 mutation (intermediate risk), and the audience was split in terms of their preferred induction regimen (BR 37%, FR 25%, FCR 20% and other 18%). This patient received FR and is doing well, but Stephanie verbalized her hope that the ongoing large German CLL study will show at least equal efficacy and perhaps greater tolerability for BR compared to FCR.
5. Bonus item for Andy Zelenetz
Prompted by an impassioned plea from Dr Z at a recent Think Tank in our Miami studio, we asked the webcast audience how they approach screening for hepatitis in patients slated to receive R. Andy — head of the NCCN NHL guidelines committee — wants to be certain clinicians realize the importance of screening such patients, and sure enough, 23% of our webcast viewers indicated they don’t routinely conduct these tests. Stephanie then described a patient in her practice who wasn’t screened and experienced reactivated hepatitis and a catastrophic clinical course after receiving R/chemo.
