Abstract
BACKGROUND Advancements in frontline therapy and chemotherapy-sparing treatments in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have altered the treatment algorithms of this disease. We present a frontline alternative for treatment- naïve (TN) CLL/SLL patients. METHODS This was a single-center, phase 2 study of high-dose methylprednisolone (HDMP) and ofatumumab with lenalidomide and ofatumumab consolidative therapy for all comers with TN CLL/SLL. Treatment was continued until disease progression or intolerable side effects. Patients were assessed for response per iwCLL 2008 criteria after completing cycles 3 and 12. RESULTS Forty-five patients were enrolled (median age, 62.6 years). High-risk features included del17p (18%), Del11q (22%), and unmutated IGHV gene (76%). Median treatment duration was 32·2 (2·7-75·9) months. Thirty-six patients discontinued treatment due to disease progression (22%), adverse events (40%), allogeneic hematopoietic cell transplantation (allo-HCT) (7%), consent withdrawal (4%), and secondary malignancies (7%). The best overall and complete response rates were 96& and 29% respectively. At median follow-up of 61·7 (5·6-84·9) months, 9 patients remained on treatment. Median progression-free survival was 54·4 (2·9-77·6) months. Three patients underwent allo-HCT after a median of 3 (3-4) treatment cycles. Treatment was well tolerated, with a grade 3/4 infusion reaction in one patient. The most common grade 3/4 hematological adverse event was neutropenia (69%). Four patients had grade 3/4 infections. No grade 3/4 tumor flares, tumor lysis syndrome, or thrombosis were observed. CONCLUSION The combination of ofatumumab, HDMP, and lenalidomide was effective and relatively well tolerated in treatment-naive CLL/SLL. Its role in the frontline setting remains unclear given the current available and effective treatment options. FUNDING The funders had no role in the study.

Abstract
Autoimmune hemolytic anemia (AIHA) and pure red cell aplasia (PRCA) are common complications of CLL. The optimal treatment of steroid refractory AIHA/PRCA is not well established. We conducted a multicenter study of ibrutinib and rituximab in patients with relapsed/refractory to steroids AIHA/PRCA and underlying CLL. Protocol included induction (ibrutinib 420 mg/day and rituximab, 8 weekly and 4 monthly infusions) and maintenance phase with ibrutinib alone until progression or unacceptable toxicity. Fifty patients were recruited (44-warm AIHA, 2-cold AIHA, 4-PRCA). After the induction 34 patients (74%) have achieved complete response, 10 (21.7%) partial response. Median time to hemoglobin normalization was 85 days. With regards to CLL response 9 (19%) patients have achieved CR, 2 (4%) patients-stabilization and 39 (78%)-PR. The median follow-up was 37.56 months. In AIHA group 2 patients had a relapse. Among 4 patients with PRCA 1 patient did not respond, and 1 patient had a relapse after CR, 2 remained in CR. The most common adverse events were neutropenia (62%), infections (72%), gastrointestinal complications (54%). In conclusion ibrutinib in combination with rituximab is an active second-line treatment option for patients with relapsed or refractory AIHA/PRCA and underlying CLL.

Obinutuzumab, High-Dose Methylprednisolone (HDMP), and Lenalidomide for the Treatment of Patients with Richter's Syndrome. Cancers (Basel) 2022; 14:cancers14246035. [PMID: 36551520 PMCID: PMC9775482 DOI: 10.3390/cancers14246035] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 11/24/2022] [Accepted: 11/29/2022] [Indexed: 12/13/2022] Open
Abstract
Background: For patients with Richter's Syndrome (RS), a durable response is rarely achieved with standard therapies. Significant efforts have focused on the development of novel treatments with reduced toxicity. We describe our experience using the novel combination of obinutuzumab, high-dose methylprednisolone (HDMP) and lenalidomide (len) in patients with RS. Patients and Methods: Eligible patients included adults with biopsy-proven RS. Patients received obinutuzumab 1000 mg × 8 doses. All patients received HDMP 1000 mg/m2 on days 1-5 of cycles 1-4. Patients were administered len PO daily, starting at a dose of 5 mg. Starting on C2D1, the dose increased every 2 weeks in 5 mg increments to a maximum of 25 mg PO daily. Results: Seven patients were treated. The median dose of len was 10 mg and the median number of cycles of treatment completed was 2. The most common grade 3/4 adverse events were neutropenia (29%) and pulmonary embolism (29%). The overall response rate for the entire cohort was 43% (95% CI, 10-82%). All patients who achieved a response underwent consolidative autologous or allogeneic stem cell transplant and remain in remission to date. Conclusions: The combination of obinutuzumab, HDMP, and len is a well-tolerated, outpatient regimen that could serve as a bridge to transplantation, or as palliation for transplant-ineligible patients with RS.

Chronic lymphocytic leukaemia/small lymphocytic lymphoma treatment with rituximab and high-dose methylprednisolone, revisited. Cancer Med 2021; 10:8768-8776.

Abstract
High‐dose methylprednisolone plus rituximab (R‐HDMP) is a useful treatment in chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL) patients unfit for chemo‐immunotherapy and has proven its utility on the treatment of CLL/SLL complicated by auto‐immune cytopenias. We performed a retrospective, single‐centre study, of CLL/SLL patients treated with R‐HDMP for 9 years. Thirty‐nine patients were included, median age at time of treatment was 77 years. Most patients had stage Rai III/IV and Binet C disease. Twenty‐eight patients had relapsed/refractory disease at time of treatment with a median of 1 previous line of therapy; 53.8% had prior exposure to fludarabine and 25% to rituximab. Grade 3–4 neutropenia and thrombocytopenia were recorded in 10.2% and 17.9% patients, respectively. While on treatment, 51.3% had documented infectious complications, but no other non‐haematological toxicities grades 3–4 were identified. Overall response rate was 64%. Median overall survival and progression‐free survival were 24 and 13 months, respectively. Twenty four patients relapsed and 16 received another line of treatment after R‐HDMP, with median time to next treatment of 13.5 months. Thirteen out of the 24 patients improved performance status and were subsequently considered fit for chemo‐immunotherapy. R‐HDMP is a valuable option for elderly and frail patients, with low risk of severe myelotoxicity and other severe adverse events. It was shown to work as a bridge to other lines of treatment, including chemo‐immunotherapy.

Abstract
INTRODUCTION Venetoclax, an oral, BCL-2 inhibitor, is approved by the FDA for treatment of CLL in all lines of therapy. Data from landmark studies, including the CLL14 and MURANO trials, demonstrated marked improvement in clinical outcomes compared to chemoimmunotherapy when venetoclax was used in combination with CD20 monoclonal antibodies for fixed treatment duration. AREAS COVERED This article reviews the mechanism of action of venetoclax and discusses how curtailing the BCL signaling pathway undermines CLL pathophysiology. The authors also give their clinical experience with the drug, with emphasis on assessing and managing the risk of venetoclax-associated tumor lysis syndrome (TLS). EXPERT OPINION Venetoclax has positioned itself as one of the primary treatment options for CLL, given the consistent efficacy and deep remissions it has elicited across multiple settings of the disease with a time-limited schedule. Accurate TLS risk evaluation and stringent adherence to the dose-escalation protocols will help optimize patient outcomes. Finally, we expect that current and future studies will (1) ascertain the ideal treatment duration using the minimal residual disease state as a guide and (2) help us understand the optimal role of venetoclax in combination or in sequence with other novel targeted therapies in the treatment of CLL.

Abstract
PURPOSE High-dose methylprednisolone (HDMP) with or without anti-CD20 antibody treatment in the pre B-cell receptor inhibitor (BCRi) era was used as potential salvage therapy for relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (r/r CLL/SLL) patients bearing the 17p deletion. PATIENTS AND METHODS Outcomes were compared in retrospect between r/r patients treated with HDMP (n = 20), ibrutinib (n = 39) and idelalisib with rituximab (n = 14). RESULTS Higher overall response rates were found in those patients undergoing BCRi therapy compared to HDMP (79.2% vs. 0%; p < 0.0001), along with longer median progression-free survival (not reached vs. 24.1 months; p < 0.01). Nevertheless, there were no differences in the overall survival (HDMP 35.87 months vs. not reached; p = 0.58). CONCLUSION HDMP treatment was significantly inferior in terms of response rate and progression-free survival in r/r CLL/SLL patients with the 17p deletion, and may only be used whenever novel compounds are unavailable.

Abstract
During the past 5 years, a number of highly active novel agents, including kinase inhibitors targeting BTK or PI3Kδ, an antagonist of the antiapoptotic protein BCL-2, and new anti-CD20 monoclonal antibodies, have been added to the therapeutic armamentarium for patients with chronic lymphocytic leukaemia (CLL). In these exciting times, care is needed to optimally integrate these novel agents into the traditional treatment algorithm without overlooking or compromising the benefits of established treatments, especially chemoimmunotherapy. A more personalized approach to CLL therapy that takes into account individual risk factors, patient characteristics, and their treatment preferences is now possible. Herein, we discuss the biological basis for the novel therapeutic agents and outline not only the major advantages of these agents over traditional therapies but also their adverse effects and the rationale for continued use of older versus newer types of therapy for selected patients with CLL. We conclude by providing recommendations for an individualized therapy approach for different populations of patients with CLL.

Abstract
Objective: To analyze the survival and first-line immune-chemotherapy (CIT) of chronic lymphocytic leukemia (CLL) with abnormal TP53 gene in the era of traditional CIT. Methods: The clinical data of 118 CLL patients diagnosed from January 2003 to August 2017 were collected. Survival was analyzed according to indicators including sex, age, Binet risk stratification, B symptoms, β(2)-microglobulin (β(2)-MG) , immunoglobulin heavy chain variable region gene (IGHV) mutation status, chromosome karyotype and TP53 gene deletion/mutation. The efficacy of first-line CIT of 101 CLL patients was further analyzed. Results: Among 118 patients, median progression-free survival (PFS) was 12 (95%CI 10.148-13.852) months and median overall survival (OS) was 53 (95%CI 41.822-64.178) months, only 30.5% patients survived over 5 years. Low β(2)-MG<3.5 mg/L indicated longer PFS (P=0.027) , female and Binet A patients had longer OS (P=0.011 and 0.013, respectively) . Of 118 patients, 17 (14.4%) didn't receive any therapy until follow-up time or the dead time. Among the 101 patients who received ≥1 CIT, median time to first treatment (TTFT) was 1 (0-62) months, patients in Binet A had longer TTFT (P<0.001) compared to the patients in Binet B/C. According to statistical needs, we divided those first-line CIT into four groups: there were 30 cases (29.7%) in mild chemotherapy group (mainly treated with nitrogen mustard phenylbutyrate or rituximab alone) , 32 cases (31.7%) in the fludarabine-containing group, 23 cases (22.8%) in high-dose methyprednisolone (HDMP) containing group and 16 cases (15.8%) in the other chemotherapy group. The first regimen contained HDMP can bring longer PFS (P<0.001) , however the OS between four groups had no statistical differences. Conclusion: CLL patients with abnormal TP53 gene had poor response to immunotherapy, rapid clinical progressing, first-line immunotherapy containing HDMP can prolong PFS and will create an opportunity for patients to participate in clinical trials of novel drugs.

BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2018; 1865:1795-1804.

Abstract
Bcl-2 inhibits cell death by at least two different mechanisms. On the one hand, its BH3 domain binds to pro-apoptotic proteins such as Bim and prevents apoptosis induction. On the other hand, the BH4 domain of Bcl-2 binds to the inositol 1,4,5-trisphosphate receptor (IP3R), preventing Ca2+ signals that mediate cell death. In normal T-cells, Bcl-2 levels increase during the immune response, protecting against cell death, and then decline as apoptosis ensues and the immune response dissipates. But in many cancers Bcl-2 is aberrantly expressed and exploited to prevent cell death by inhibiting IP3R-mediated Ca2+ elevation. This review summarizes what is known about the mechanism of Bcl-2's control over IP3R-mediated Ca2+ release and cell death induction. Early insights into the role of Ca2+ elevation in corticosteroid-mediated cell death serves as a model for how targeting IP3R-mediated Ca2+ elevation can be a highly effective therapeutic approach for different types of cancer. Moreover, the successful development of ABT-199 (Venetoclax), a small molecule targeting the BH3 domain of Bcl-2 but without effects on Ca2+, serves as proof of principle that targeting Bcl-2 can be an effective therapeutic approach. BIRD-2, a synthetic peptide that inhibits Bcl-2-IP3R interaction, induces cell death induction in ABT-199 (Venetoclax)-resistant cancer models, attesting to the value of developing therapeutic agents that selectively target Bcl-2-IP3R interaction, inducing Ca2+-mediated cell death.

Abstract
Recent developments in the diagnosis and treatment of chronic lymphocytic leukemia (B-CLL) have led to change of approach in clinical practice. New treatments have been approved based on the results of randomized multicenter trials for first line and for salvage therapy, and the results of numerous ongoing clinical trials are permanently providing new answers and further refining of therapeutic strategies. This is paralleled by substantial increase in understanding the disease genetics due to major advances in the next generation sequencing (NGS) technology. We define current position of the Croatian Cooperative Group for Hematologic Disease on diagnosis and treatment of CLL in the transition from chemo-immunotherapy paradigm into a new one that is based on new diagnostic stratification and unprecedented therapeutic results of B-cell receptor inhibitors (BRI) and Bcl-2 antagonists. This is a rapidly evolving field as a great number of ongoing clinical trials con-stantly accumulate and provide new knowledge. We believe that novel therapy research including genomic diagnosis is likely to offer new options that will eventually lead to time limited therapies without chemotherapy and more effective clinical care for B-CLL based on individualized precision medicine.

Abstract
With the recent approval of several effective and well-tolerated novel agents (NAs), including ibrutinib, idelalisib, venetoclax, and obinutuzumab, patients with chronic lymphocytic leukemia (CLL) have more therapeutic options than ever before. The availability of these agents is both an important advance for patients but also a challenge for practicing hematologist/oncologists to learn how best to sequence NAs, both with respect to chemoimmunotherapy (CIT) and to other NAs. The sequencing of NAs in clinical practice should be guided both by an individual patient's prognostic markers, such as FISH and immunoglobulin heavy chain variable region (IGHV)-mutation status, as well as the patient's medical comorbidities and goals of care. For older, frailer patients with lower-risk CLL prognostic markers, NA monotherapy may remain a mainstay of CLL treatment for years to come. For younger, fitter patients and those with higher-risk CLL, such as del(17p) or unmutated IGHV, combination approaches may prove to be more valuable than NA monotherapy. Trials are currently evaluating the efficacy of several such combination approaches, including NA plus anti-CD20 monoclonal antibody, NA plus NA (with or without anti-CD20 monoclonal antibody), and NA plus CIT. Given the tremendous efficacy of the already approved NAs, as well as the promising data for next generation NAs, the development of well-tolerated, highly effective combination strategies with curative potential for patients with CLL has become a realistic goal.

Abstract
OPINION STATEMENT The front-line management of patients with chronic lymphocytic leukemia (CLL) has evolved significantly in recent years due to introduction of novel, targeted agents. Upon CLL diagnosis, physicians should determine whether treatment or careful observation is indicated. Once treatment is required, choice of therapy should be based on the age and fitness of the patient and the distinct molecular profile of their disease. As multiple novel agents are in various stages of development, all patients regardless of their age, fitness, and disease risk should be evaluated for clinical trial participation before initiating any front-line therapy. If no clinical trial is available, we provide our recommendations for front-line treatment of CLL patients. Healthy, young patients with low-risk disease (mutated IgVH, del (13q)) should be offered fludarabine, chlorambucil, and rituximab (FCR), while similar patients with high-risk disease (unmutated IgVH, del (17p), del (11q), and complex karyotype) should be considered for ibrutinib therapy. For those young, fit patients with high-risk disease and a contraindication to ibrutinib, FCR, or high-dose methylprednisolone and rituximab are options. In regard to older, unfit patients, a careful assessment of their fitness and ability to tolerate treatment should be undertaken before starting therapy. Those who have poor performance and multiple medical comorbidities should be considered for palliative care alone. However, those who are fit enough for treatment can be offered ibrutinib. If there is a contraindication to ibrutinib, they can be separated into low- and high-risk molecular groups. For the low-risk patients, bendamustine and rituximab or obinutuzumab and chlorambucil can be considered. For the high-risk patients, treatment with rituximab and lenalidomide is an option. Herein, we provide an evidence-based front-line treatment algorithm for CLL patients based upon fitness and molecular risk.

Abstract
More effective therapies are emerging, with better toxicity profiles, and are being incorporated into modern treatment algorithms of chronic lymphocytic leukemia at various stages of the disease, including for patients harboring Del17p and/or aberrant TP53. Ibrutinib, an inhibitor of Bruton's tyrosine kinase, has demonstrated impressive response rates in the relapsed/refractory setting, including in the setting of Del17p and/or TP53 mutations. Venetoclax, an inhibitor of BCL-2 known to play an important role in regulating cell death, has been approved recently for treatment of patients with chronic lymphocytic leukemia with Del17p who have received at least one prior therapy. Unfortunately, a cure remains unattainable unless eligible patients are offered an allogeneic hematopoietic cell transplant. However, hematopoietic cell allografting is limited by the availability of suitable donors and significant morbidity and mortality. Recent clinical practice recommendations by the American Society for Blood and Marrow Transplantation have relegated the role of transplantation to later stages of the disease. In patients with evidence of Richter syndrome, frontline consolidation allogeneic hematopoietic cell transplantation remains the most desirable approach owing to the limited activity of ibrutinib or other novel therapies. Further therapeutic advances would require enrolling these patients in large clinical trials that evaluate novel therapies alone or in combination with traditional chemotherapies or even in the setting of posttransplant consolidation/maintenance.

Abstract
Objective This study aims to evaluate the natural history of patients with chronic lymphocytic leukemia (CLL) and a 17p deletion (17p-) and identify the predictive factors within this subgroup. Methods The sample of patients with CLL were analyzed by fluorescencein situ hybridization for deletions in chromosome bands 11q22, 13q14 and 17p13; trisomy of bands 12q13; and translocation involving band 14q32. The data from 456 patients with or without a 17p- were retrospectively collected and analyzed.
Results The overall response rate (ORR) in patients with a 17p- was 56.9%, and patients with a high percentage of 17p- (defined as more than 25% of cells harbouring a 17p-) had a lower ORR. The median overall survival (OS) in patients with a 17p- was 78.0 months, which was significantly shorter than the OS in patients without this genetic abnormality (median 162.0 months, P<0.001). Within the subgroup with a 17p-, the progression-free survival was significantly shorter in patients at Binet stage B-C and patients with elevated lactate dehydrogenase (LDH), B symptoms, unmutatedIGHV and a high percentage of 17p-.
Conclusions These results indicated that patients with a 17p- CLL have a variable prognosis that might be predicted using simple clinical and laboratory characteristics.

Abstract
It is an unprecedented time for the treatment of patients with chronic lymphocytic leukemia (CLL) with the recent approval of several targeted agents for use in frontline, relapsed, refractory, and high-risk disease. Traditionally, frontline management of CLL has been a combination of chemotherapy (fludarabine, cyclophosphamide, bendamustine, or chlorambucil) with an anti-CD20 monoclonal antibody (rituximab, ofatumumab, obinutuzumab). The current landscape is rapidly evolving with the advent of therapies that demonstrate selective inhibition of important pathways necessary for CLL proliferation and survival. Despite considerable progress, much is still unknown and optimal treatment selection and sequence is still debatable. None of the new agents have been compared against each other and the impact of adding an additional agent to monotherapy is not yet fully elucidated. In routine clinical practice, the choice of therapy is based on nonrandomized comparisons, presence of comorbidities, and toxicity considerations. These recently approved drugs (ibrutinib, idelalisib, and venetoclax) are reporting excellent outcomes, including patients with high-risk disease such as 17p deletion (17p-) or TP53 mutations (TP53mut). Ibrutinib and venetoclax have been approved for use in 17p- patients (frontline and relapsed, respectively). Ibrutinib is currently moving into the frontline space given recent regulatory approvals. This review will summarize and interpret the limited therapeutic sequencing data available, highlighting the need for additional studies to optimize combination strategies and treatments after failure or discontinuation of these novel agents.

Abstract
The aim of this study was to analyze the population‐based frequency of classic (c‐) and biologic (b‐) disease‐modifying antirheumatic drug (DMARD) use over time, selected underlying indications and the specialty of the prescribing physicians in Germany. Based on the claims data of the German Pharmacoepidemiological Research Database (GePaRD), yearly cross‐sectional studies were conducted from 2004 to 2011. The prevalence of DMARD use was calculated as the number of persons with at least one dispensation per 1000 persons stratified by sex and age. In 2011, we also obtained the proportion of c‐ and b‐DMARDs users with diagnoses of selected indications and the proportion of dispensations by specialty of the physician. Between 2004 and 2011, the annual prevalence of b‐DMARD and c‐DMARD use increased from 0.35‰ to 1.54‰ and from 6.53‰ to 8.93‰, respectively. In 2011, the study population comprised 12.8 million insurants with a mean age of 44.0 years. During this year, among c‐DMARDs, methotrexate was prescribed most frequently (4.76‰), followed by azathioprine (1.72‰) and sulfasalazine (1.20‰). For b‐DMARDs, adalimumab (0.57‰), etanercept (0.46‰), and rituximab (0.23‰) were most frequently used. Notably, b‐DMARD users more often had a diagnosis of ankylosing spondylitis and psoriasis compared to c‐DMARD‐users (20.7% vs. 2.9% and 20.0% vs. 11.4%, respectively) and b‐DMARDs were more frequently prescribed by rheumatologists and other specialists. Our population‐based study highlights the increasing use of c‐ and b‐DMARDs in Germany. Compared to c‐DMARDs, b‐DMARDs were commonly used for indications besides rheumatoid arthritis. Future research should therefore also focus on their prescription patterns and safety aspects in indications other than RA.

Abstract
Hematologic malignancies are a common cause of morbidity and mortality among older adults, who represent the majority of patients diagnosed with these diseases. Treatment options and disease outcomes have improved in recent years because of the development of novel treatment strategies and the design of elderly-specific clinical trials. Despite this, extrapolation of clinical trial data to patients routinely seen in practice is challenging because of the presence of multimorbidity and functional impairments. Individualized treatment decision making requires not only an understanding of underlying tumor biology but also careful estimation of an older patient's anticipated ability to withstand the stresses of therapy. This article will discuss approaches to standardizing patient assessment strategies and tailoring therapeutic decisions for older adults with hematologic malignancies with a focus on acute myeloid leukemia (AML), allogeneic bone marrow transplantation, multiple myeloma (MM), and chronic lymphocytic leukemia (CLL).

Abstract
INTRODUCTION High-dose methylprednisolone (HDMP) in combination with rituximab is active in the treatment of relapsed/refractory chronic lymphocytic leukemia (CLL), but serious infections are frequent. Recently published data suggested that high-dose dexamethasone might be equally effective as HDMP despite a lower cumulative dose. MATERIAL AND METHODS We performed retrospective analysis of 60 patients with relapsed/refractory CLL (median age: 66 years; range: 37-86) treated with rituximab plus dexamethasone (R-dex) at a single tertiary center between September 2008 and October 2012. The schedule of R-dex consisted of rituximab 500 mg/m(2) i.v. day 1 (375 mg/m(2) in cycle 1) and dexamethasone 40 mg orally on days 1-4 and 10-13 repeated every 3 weeks for a maximum of 8 cycles. Unfavorable prognostic features were frequent (Rai stages III/IV in 67%, unmutated IgVH 82%, del 11q 43%, TP53 mutation/deletion 23%, bulky lymphadenopathy 58% of patients). RESULTS Overall response (OR)/complete remission (CR) was achieved in 75/3%. At the median follow-up of 21 months, median progression-free survival (PFS) was 8 months, median time to next treatment 12.9 months and median overall survival 25.5 months. Refractoriness to fludarabine (p = 0.04) and age ≥ 65 years (p = 0.03) were significant predictors of shorter PFS. R-dex was successfully used for debulking before allogenic stem cell transplantation in 7 patients (12%). Serious (CTCAE grade III/IV) infections occurred in 27% of patients; 20% of patients developed steroid diabetes requiring temporary short-acting insulin. CONCLUSIONS Our results show that R-dex is an active and well-tolerated regimen for patients with relapsed/refractory CLL; however, major infections remain frequent despite combined antimicrobial prophylaxis.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common leukemia. Combined agent chemotherapy is the current standard front-line treatment for physically fit patients with CLL. Use of chemotherapy can be complicated by significant toxicity, especially in patients with advanced age or comorbid conditions. Moreover, patients may relapse and become refractory to further chemotherapy. Immunotherapy targets the aberrant immunological processes in CLL without the toxicity of chemotherapy. Immunotherapeutic strategies can also be combined with chemotherapy to improve response rates in this incurable disease. In this review, we evaluate current and future immune-based options in the treatment of CLL.

Abstract
Only chronic lymphocytic leukemia (CLL) patients with active or symptomatic disease or with advanced Binet or Rai stages require therapy. Prognostic risk factor profile and comorbidity burden are most relevant for the choice of treatment. For physically fit patients, chemoimmunotherapy with fludarabine, cyclophosphamide, and rituximab remains the current standard therapy. For unfit patients, treatment with an anti-CD20 antibody (obinutuzumab or rituximab or ofatumumab) plus milder chemotherapy (chlorambucil) may be applied. Patients with a del(17p) or TP53 mutation should be treated with the kinase inhibitors ibrutinib or a combination of idelalisib and rituximab. Clinical trials over the next several years will determine, whether kinase inhibitors, other small molecules, immunotherapeutics, or combinations thereof will further improve outcomes for patients with CLL.

Abstract
High dose methylprednisolone (HDMP) has been an effective salvage therapy for patients with relapsed chronic lymphocytic leukemia (CLL), while little is known about the exact mechanisms implicated in glucocorticoid-induced cell death. To explore the mechanism of glucocorticoid-induced cell death, we investigated the effect of HDMP on canonical Wnt signaling which emerged as a key pathway implicated in the pathogenesis of CLL. In this study, the human CLL cell line MEC-1 was incubated with various concentrations of methylprednisolone. Cell proliferation activity was detected by CCK8 assay, the apoptotic effect was evaluated by TUNEL assay. Western blot was used to detect active-caspase 3, and the key proteins in Wnt signaling pathway (LEF-1, β-catenin). RT-PCR was performed to assess the mRNA levels of β-catenin, LEF-1, c-myc and cyclin D1. We observed that high concentration of methylprednisolone could suppress the proliferation activity of MEC-1 cells, promote the relative expression of active-caspase 3, and induce apoptotic cell death. Furthermore, methylprednisolone could inhibit LEF-1 protein expression, consequently down-regulate mRNA levels of c-myc and cyclin D1, but could not affect the transcription level of β-catenin and LEF-1 mRNA. The results of this study indicate that methylprednisolone can suppress Wnt signaling pathway by down-regulating LEF-1 protein expression, indicating a novel mechanism for HDMP therapy in CLL.

Abstract
Ofatumumab is a humanized anti-CD20 monoclonal antibody that has been approved by the FDA for the treatment of patients with chronic lymphocytic leukemia. We conducted a phase II single-arm study at a single center. Patients received ofatumumab (300 mg then 1000 mg weekly for 12 weeks) and methylprednisolone (1000 mg/m2 for 3 days of each 28-day cycle). Twenty-one patients enrolled, including 29% with unfavorable cytogenetics (del17p or del11q). Ninety percent of patients received the full course without dose reductions or delays. The overall response rate was 81% (17/21) with 5% complete response, 10% nodular partial response, 67% partial response, 14% stable disease and 5% progressive disease. After a median follow-up of 31 months, the median progression-free survival was 9.9 months and the median time to next treatment was 12.1 months. The median overall survival has not yet been reached. The combination of high-dose methylprednisolone and ofatumumab is an effective and tolerable treatment regimen. This regimen may be useful for patients who are unable to tolerate more aggressive therapies, or have not responded to other treatments.

Abstract
To determine the prognostic impact of de novo deletion 17p13.1 (17p-) in previously untreated chronic lymphocytic leukemia (CLL) patients, we prospectively studied the outcome of 71 treatment-naïve CLL patients. About 18.3 % of them had 17p- detected by interphase fluorescent in situ hybridization (FISH) at diagnosis. There was statistically significant difference between 17p- negative and positive patients as regards 2-year overall survival [OS] (89.7 vs. 53.8 %, respectively; P = 0.001). On the other hand, 2-year progression-free survival [PFS] was also significantly higher in 17p- negative group than in 17p- positive one (82.8 vs. 23.1 %, respectively; P < 0.001). On univariate analysis for OS, 17p- positivity was significantly associated with shorter OS (P = 0.003). However, when we performed multivariate analysis, 17p- lost its significant impact. On the other hand, 17p- positivity was a significant risk factor for PFS in both univariate and multivariate analyses [independent risk factor] (P < 0.001 and P = 0.02, respectively). So, 17p- is a predictor for disease progression, but not for survival in CLL patients.

Abstract
In the last decade, the management of chronic lymphocytic leukemia has undergone profound changes that have been driven by an improved understanding of the biology of the disease and the approval of several new drugs. Moreover, many novel drugs are currently under evaluation for rapid approval or have been approved by regulatory agencies, further broadening the available therapeutic armamentarium for patients with chronic lymphocytic leukemia. The use of novel biological and genetic parameters combined with a careful clinical evaluation allows us to dissect some of the heterogeneity of the disease and to distinguish patients with a very mild onset and course, who often will not need any treatment, from those with an intermediate prognosis and a third group with a very aggressive course (high-risk leukemia). On this background, it becomes increasingly challenging to select the right treatment strategy. In this paper, we describe our own approach to the management of different patients with chronic lymphocytic leukemia.

Abstract
Although uncommon in treatment-naive patients with chronic lymphocytic leukemia, deletion 17p is a high-risk disease characteristic. We analyzed and reported outcomes for 63 patients with deletion 17p chronic lymphocytic leukemia who received first-line therapy at our institution; at time of first treatment, 81% had unmutated immunoglobulin heavy chain variable gene and 58% had complex karyotype. Forty-nine patients (76%) received first-line fludarabine, cyclophosphamide, rituximab-based therapy, 6 (11%) received rituximab-based and 8 (13%) received lenalidomide-based treatment. Overall, the complete plus nodular partial remission rate was 33%; on multivariable model, higher complete plus nodular partial remission rate was observed in patients with less than 50% cells positive for deletion 17p, and a higher probability of achieving at least a partial remission was observed with fludarabine, cyclophosphamide, rituximab-based treatment. After a median follow up of 33 months (range 1-89 months), the estimated median progression-free survival was 14 months (95% confidence interval 10-18) and estimated median overall survival was 63 months (95% confidence interval 43-83). In multivariable analysis, factors independently associated with longer progression-free survival were response to treatment and absence of complex karyotype. Achievement of complete plus nodular partial remission rate and mutated immunoglobulin heavy chain variable gene were independently associated with longer overall survival in multivariable model. Complex karyotype was associated with increased risk for Richter's transformation. New first-line strategies and agents must aim at both improving response and maintaining remission in patients with deletion 17p, particularly in the presence of complex karyotype.

Abstract
Chronic lymphocytic leukemia (CLL) that becomes refractory to chemotherapy is associated with a poor outcome. For these patients, some of the novel substances that are currently in clinical development for CLL seem to offer new hope. These agents include small molecules, new antibodies, immunomodulators, kinase inhibitors, BCL-2 antagonists and chimeric antigen receptor transduced T-cells (CARTs) and combine high efficacy with a good safety profile. To date, allogeneic stem cell transplant remains the only curative treatment option for patients with relapsed, refractory CLL. However, it is possible that new substances will replace allogeneic stem cell transplant in the near future. This review provides an overview of the currently available data and an outlook on future therapies for chemotherapy refractory CLL.

Abstract
BACKGROUND Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the western world. Recent advances in understanding the biology of B-cell malignancies have resulted in the development of novel agents targeting key prosurvival pathways in the neoplastic B cell. OBJECTIVE The goal of this article was to summarize current literature on the emerging therapeutic approaches in CLL and B-cell malignancies. METHODS A literature review was performed, identifying pathways and key clinical trials involving novel therapies in CLL, with special emphasis on B-cell receptor (BCR)-targeting agents. RESULTS Understanding the biology of the BCR-signaling pathway has led to identification of novel molecular targets. Most notably, inhibitors of Bruton tyrosine kinase and phosphatidylinositide 3-kinase-δ have entered clinical trials and demonstrated high response rates in CLL, including high-risk disease. Cyclin-dependent kinase inhibitors may evolve into an alternative therapeutic approach in CLL. New drugs that target molecules within and outside of the BCR-signaling pathway have shown promise in preclinical studies. CONCLUSIONS Both preclinical and early clinical trial results involving novel targeted therapies suggest that the standard treatment paradigm in CLL and B-cell malignancies will soon change. Particular attention should be paid to the BCR-targeting agents, whose favorable adverse effect profile may improve the lives of elderly patients with CLL.

Abstract
Understanding the pathogenesis of CLL has uncovered a plethora of novel targets for human application of monoclonal antibodies, engineered T cells, or inhibitors of signal transduction pathways. The B-cell receptor signaling pathway is being actively explored as a therapeutic target in CLL. Ibrutinib, an inhibitor of Bruton's tyrosine kinase is showing impressive responses in heavily pre-treated high-risk CLL, whether alone or in combination with MoAbs or chemotherapy. Other key components of the BCR pathway, namely PI3K-δ, are also being targeted with novel therapies with promising results as well. Future trials would likely evaluate ibrutinib in the front-line setting. Moreover, improvements in allogeneic HCT mostly by continuing to reduce associated toxicity as well as incorporating cellular therapies such as autologous CLL tumor vaccines, among others, will continue to expand. This is also the case for the next generation of chimeric antigen receptor therapy for CLL once genetically modified T cells are available at broad scale and with improved efficacy. As our ability to further refine and integrate these therapies continues to improve, and we gain further knowledge from gene sequencing, we anticipate that treatment algorithms will continue to be revised to a more personalized approach to treat this disease with improved efficacy and devoid of unnecessary toxicity.

Abstract
AbstractDespite the advanced age at onset, chronic lymphocytic leukemia (CLL) shortens the life expectancy of the majority of newly diagnosed patients. The management of elderly patients with CLL is more complex than that of younger patients due to the greater frequency of comorbidities and functional impairment as well as reduced organ function. Many of the recent advances in the care of CLL patients (prognostication, more intense combination therapy regimens) are of unclear relevance for elderly patients. This review addresses 5 key questions in the management of elderly patients with CLL: (1) why is classifying the “fitness” of CLL patients necessary; (2) what criteria should be used to classify patient fitness; (3) when should elderly patients be treated; (4) how should therapy be selected for elderly patients; and (5) which therapy is best (for this patient)?

Rituximab is an effective treatment for autoimmune cytopenias associated with chronic lymphocytic leukemia. Despite the incorporation of rituximab into fludarabine-based chemotherapy regimens, the incidence of autoimmune cytopenias has remained high. Inadequate rituximab exposure due to rapid antibody clearance may be a contributing factor. To test this hypothesis, we measured serum rituximab levels in patients treated with fludarabine and rituximab (375 mg/m(2)). All patients had undetectable rituximab trough levels by the end of cycle 1, and one-third had undetectable levels already on Day 6 of cycle 1. Although rituximab trough levels increased progressively with each cycle, only by cycle 4 did the median trough level exceed 10 ug/mL. The median half-life of rituximab during cycle 1 was 27 hours, compared to 199 hours during cycle 4 (P<0.0001). There was a significant inverse correlation between the rituximab half-life in cycle 1 and the degree of tumor burden (P=0.02). Two patients who were identified as having subclinical autoimmune hemolysis prior to therapy were given additional doses of rituximab during the initial cycles of therapy and did not develop clinically significant hemolysis. One patient who developed clinically significant hemolysis during therapy was given additional rituximab doses during cycles 3-5 and was able to successfully complete his treatment. In conclusion, rituximab is cleared so rapidly during the initial cycles of therapy for chronic lymphocytic leukemia that most patients have only transient serum levels. More frequent dosing of rituximab may be required to prevent autoimmune complications in at-risk patients (clinicaltrials.gov identifier:00001586).

Abstract
INTRODUCTION The last decade has witnesd immense progress in the treatment of chronic lymphocytic leukemia (CLL). Chemoimmunotherapy (CIT) combining rituximab and fludarabine with cyclophosphamide (FCR) in the frontline setting has clearly been shown to improve outcomes in patients with CLL. Building on the success achieved with rituximab, other anti-CD20 monoclonal antibodies (mAbs) are being investigated. Novel bioengineering techniques have helped in the development of anti-CD20 mAbs. One antibody, ofatumumab, was recently approved for the treatment of refractory CLL. A type II anti-CD20 mAb, GA-101 (obinutuzumab), is currently in clinical trials. This short review focuses on ongoing clinical trials of anti-CD20 mAbs in CLL. AREAS COVERED Literature search was performed using PubMed ( www.clinicaltrials.gov (till August 2012)), and recent American Society of Clinical Oncology (ASCO), American Society of Hematology (ASH), European Hematology association (EHA), International workshop on CLL (iwCLL) abstracts, using the primary search terms 'anti-CD20 monoclonal antibody' with/without CLL. Articles were chosen on the basis of relevance of anti-CD20 mAbs to CLL therapy. EXPERT OPINION Rituximab, the prototype anti-CD20 mAb, forms the core of CIT in CLL. The success of rituximab and ofatumumab has led investigators to evaluate other anti-CD20 mAbs in the treatment of CLL.

Abstract
The quantification of submicroscopic minimal residual disease (MRD) after therapy proved to have independent prognostic significance in many mature B-cell malignancies. With the advent of routine bench-top cytometers capable of simultaneously analyzing ≥ 4 colors and with improved standardization, flow cytometry has become the method of choice for MRD assessments in some lymphoma entities. Herein we describe general aspects of flow cytometric standardization. Using chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL) as examples we explain in detail the application of flow cytometry for MRD detection.

Abstract
BACKGROUND Chronic lymphocytic leukaemia (CLL) accounts for 25% of all leukaemias and is the most common lymphoid malignancy in western countries. Standard treatments include mono- or polychemotherapies, usually combined with monoclonal antibodies such as rituximab or alemtuzumab. However, the impact of these agents remains unclear, as there are hints for increased risk of severe infections. OBJECTIVES The objectives of this review are to provide an evidence-based answer regarding the clinical benefits and harms of monoclonal anti-CD20 antibodies (such as rituximab, ofatumumab, GA101) compared to no further therapy or to other anti-leukaemic therapies in patients with CLL, irrespective of disease status. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 12, 2011), MEDLINE (from January 1990 to 4 January 2012), and EMBASE (from 1990 to 20 March 2009) as well as conference proceedings (American Society of Hematology, American Society of Clinical Oncology, European Hematology Association and European Society of Medical Oncology) for randomised controlled trials (RCTs). SELECTION CRITERIA We included RCTs examining monoclonal anti-CD20 antibodies compared to no further therapy or to anti-leukaemic therapy such as chemotherapy or monoclonal antibodies in patients with newly diagnosed or relapsed CLL. DATA COLLECTION AND ANALYSIS We used hazard ratios (HR) as effect measures for overall survival (OS), progression-free survival (PFS) and time to next treatment, and risk ratios (RR) for response rates, treatment-related mortality (TRM) and adverse events (AEs). Two review authors independently extracted data and assessed quality of trials. MAIN RESULTS We screened a total of 1150 records. Seven RCTs involving 1763 patients were identified, but only five could be included in the two separate meta-analyses we performed. We judged the overall the quality of these trials as moderate to high. All trials were randomised and open-label studies. However, two trials were published as abstracts only, therefore we were unable to assess the potential risk of bias for these trials in detail.Three RCTs (N = 1421) assessed the efficacy of monoclonal anti-CD20 antibodies (i.e. rituximab) plus chemotherapy compared to chemotherapy alone. The meta-analyses showed a statistically significant OS (HR 0.78, 95% confidence interval (CI) 0.62 to 0.98, P = 0.03, the number needed to treat for an additional beneficial effect (NNTB) was 12) and PFS (HR 0.64, 95% CI 0.55 to 0.74, P < 0.00001) advantage for patients receiving rituximab. In the rituximab-arm occurred more AEs, World Health Organization (WHO) grade 3 or 4 (3 trials, N = 1398, RR 1.15, 95% CI 1.08 to 1.23, P < 0.0001; the number needed to harm for an additional harmful outcome (NNTH) was 9), but that did not lead to a statistically significant difference regarding TRM (3 trials, N = 1415, RR 1.19, 95% CI 0.70 to 2.01, P = 0.52).Two trials (N = 177) evaluated rituximab versus alemtuzumab. Neither study reported OS or PFS. There was no statistically significant difference between arms regarding complete response rate (CRR) (RR 1.21, 95% CI 0.94 to 1.58, P = 0.14) or TRM (RR 0.31, 95% CI 0.06 to 1.51, P = 0.15). However, the CLL2007FMP trial was stopped early owing to an increase in mortality in the alemtuzumab arm. More serious AEs occurred in this arm (43% with alemtuzumab versus 22% with rituximab; P = 0.006).Two trials assessed different dosages or time schedules of monoclonal anti-CD20 antibodies. One trial (N = 104) evaluated two different rituximab schedules (concurrent arm: fludarabine plus rituximab (Flu-R) plus rituximab consolidation versus sequential arm: fludarabine alone plus rituximab consolidation). The comparison of the concurrent versus sequential regimen of rituximab showed a statistically significant difference of the CRR with 33% in the concurrent-arm and 15% in the sequential-arm (P = 0.04), that did not lead to statistically significant differences regarding OS (HR 1.14, 95% CI 0.20 to 6.65, P = 0.30) or PFS (HR 0.96, 95% CI 0.43 to 2.15, P = 0.11). Furthermore results showed no differences in occurring AEs, except for neutropenia, which was more often observed in patients of the concurrent arm. The other trial (N = 61) investigated two different dosages (500 mg and 1000 mg) of ofatumumab in addition to FluC. The arm investigating ofatumumab did not assess OS and a median PFS had not been reached owing to the short median follow-up of eight months. It showed no statistically significant differences between arms regarding CRR (32% in the FCO500 arm versus 50% in the FCO1000 arm; P = 0.10) or AEs (anaemia, neutropenia, thrombocytopenia). AUTHORS' CONCLUSIONS This meta-analysis showed that patients receiving chemotherapy plus rituximab benefit in terms of OS as well as PFS compared to those with chemotherapy alone. Therefore, it supports the recommendation of rituximab in combination with FluC as an option for the first-line treatment as well as for the people with relapsed or refractory CLL. The available evidence regarding the other assessed comparisons was not sufficient to deduct final conclusions.

Abstract
Central nervous system (CNS) involvement by chronic lymphocytic leukemia (CLL) can present with dramatic neurologic findings or can be quite subtle, discovered only at the time of autopsy. We describe a case of CLL in a patient who presented initially with hearing loss and was ultimately found to have involvement of the tympanic membrane. She noted improvement of her hearing after induction therapy but was not aware at the time of the involvement of her CNS with CLL. Upon worsening of hearing at the time of relapse, she was evaluated by imaging and CSF analysis as well as biopsy of the tympanic membrane, and involvement of the CNS was confirmed. She has received CNS-directed therapy with intrathecal liposomal cytarabine and intravenous CNS-directed therapy and has noted improved hearing and resolution of her imaging and CSF findings. This is the first reported case of tympanic membrane involvement with CLL and describes potentially effective methods for managing this challenging complication.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world and remains incurable with conventional chemotherapy treatment approaches. CLL as a disease entity is defined by a relatively parsimonious set of diagnostic criteria and therefore likely constitutes an umbrella term for multiple related illnesses. Of the enduring fundamental biological processes that affect the biology and clinical behavior of CLL, few are as central to the pathogenesis of CLL as recurrent acquired genomic copy number aberrations (aCNA) and recurrent gene mutations. Here, a state-of-the-art overview of the pathological anatomy of the CLL genome is presented, including detailed descriptions of the anatomy of aCNA and gene mutations. Data from SNP array profiling and large-scale sequencing of large CLL cohorts, as well as stimulated karyotyping, are discussed. This review is organized by discussions of the anatomy, underlying pathomechanisms and clinical significance of individual genomic lesions and recurrent gene mutations. Finally, gaps in knowledge regarding the biological and clinical effects of recurrent genomic aberrations or gene mutations on CLL are outlined to provide critical stimuli for future research.

Abstract
Despite the combinations of chemotherapy with monoclonal antibodies have further improved response rates, chronic lymphocytic leukemia (CLL) remains an incurable disease with an extremely variable course. This article reviews the ongoing clinical advances in the treatment of CLL in both previously untreated and relapsed disease and focuses on the benefit of different therapeutic strategies, the most effective therapy combinations and the potential activity of novel agents. Novel agents and combination therapies have been investigated by several studies in both the upfront and relapsed setting, particularly for patients with 17p deletion, TP53 mutation and fludarabine-refractory CLL. While these agents and combination therapies have improved initial response rates, ongoing studies are continued to determine and improve the efficacy and safety. Despite advancements in the treatment of CLL have led to high response rates, allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only curative option and reduced-intensity conditioning (RIC) allo-HSCT must be strongly considered whenever feasible. As such, ongoing studies of these agents and other novel approaches in clinical development are needed to expand and improve treatment options for CLL patients.

Abstract
Glucocorticoids (GCs) represent an important component of modern treatment regimens for fludarabine-refractory or TP53-defective chronic lymphocytic leukemia (CLL). However, GC therapy is not effective in all patients. The molecular mechanisms responsible for GC-induced apoptosis and resistance were therefore investigated in primary malignant cells obtained from a cohort of 46 patients with CLL. Dexamethasone-induced apoptosis was unaffected by p53 dysfunction and more pronounced in cases with unmutated IGHV genes. Cross-resistance was observed between dexamethasone and other GCs but not fludarabine, indicating non-identical resistance mechanisms. GC treatment resulted in the upregulation of Bim mRNA and protein, but to comparable levels in both GC-resistant and sensitive cells. Pre-incubation with Bim siRNAs reduced GC-induced upregulation of Bim protein and conferred resistance to GC-induced apoptosis in previously GC-sensitive cells. GC-induced upregulation of Bim was associated with the activation of Bax and Bak in GC-sensitive but not -resistant CLL samples. Co-immunoprecipitation experiments showed that Bim does not interact directly with Bax or Bak, but is almost exclusively bound to Bcl-2 regardless of GC treatment. Taken together, these findings suggest that the GC-induced killing of CLL cells results from the indirect activation of Bax and Bak by upregulated Bim/Bcl-2 complexes, and that GC resistance results from the failure of such activation to occur.

Abstract
BACKGROUND Recent advances in the treatment of chronic lymphocytic leukemia (CLL) have moved beyond the traditional use of alkylating agents and purine analogs into regimens combining these two chemotherapy classes with monoclonal antibodies. METHODS This article reviews treatments options for patients with relapsed or refractory CLL. RESULTS Several studies have investigated novel agents in treating patients with 17p deletion, TP53 mutation, and fludarabine-refractory CLL, as well as patients with suboptimal response to intense treatment. These investigational agents include rituximab, alemtuzumab, ofatumumab, bendamustine, high-dose methylprednisolone, lenalidomide, lumiliximab, cyclin-dependent kinase inhibitors, small modular immunopharmaceuticals, Bcl-2 inhibitors, and histone deacetylase inhibitors. While these newer drugs and combination therapies have shown promise as treatment options for CLL, additional studies are needed to determine the immunosuppression, toxicities, and infections associated with their use. CONCLUSIONS Despite improvement in initial overall response rates, most patients relapse and require further treatment. CLL remains incurable with standard therapies due to development of disease refractoriness. As such, novel approaches such as those noted above warrant continued research to improve outcomes for patients with CLL.

Abstract
Purpose To determine the clinical significance of flow cytometric minimal residual disease (MRD) quantification in chronic lymphocytic leukemia (CLL) in addition to pretherapeutic risk factors and to compare the prognostic impact of MRD between the arms of the German CLL Study Group CLL8 trial. Patients and Methods MRD levels were prospectively quantified in 1,775 blood and bone marrow samples from 493 patients randomly assigned to receive fludarabine and cyclophosphamide (FC) or FC plus rituximab (FCR). Patients were categorized by MRD into low- (< 10−4), intermediate- (≥ 10−4 to <10−2), and high-level (≥ 10−2) groups. Results Low MRD levels during and after therapy were associated with longer progression-free survival (PFS) and overall survival (OS; P < .0001). Median PFS is estimated at 68.7, 40.5, and 15.4 months for low, intermediate, and high MRD levels, respectively, when assessed 2 months after therapy. Compared with patients with low MRD, greater risks of disease progression were associated with intermediate and high MRD levels (hazard ratios, 2.49 and 14.7, respectively; both P < .0001). Median OS was 48.4 months in patients with high MRD and was not reached for lower MRD levels. MRD remained predictive for OS and PFS in multivariate analyses that included the most important pretherapeutic risk markers in CLL. PFS and OS did not differ between treatment arms within each MRD category. However, FCR induced low MRD levels more frequently than FC. Conclusion MRD levels independently predict OS and PFS in CLL. Therefore, MRD quantification might serve as a surrogate marker to assess treatment efficacy in randomized trials before clinical end points can be evaluated.
