RESUMEN
BACKGROUND: Follicular lymphoma (FL) and marginal zone lymphoma (MZL) are indolent non-Hodgkin lymphomas (iNHL). Median survival for iNHL is approximately 20 years. Because standard treatments are not curative, patients often receive multiple lines of therapy with associated toxicity-rationally designed, combination therapies with curative potential are needed. The immunomodulatory drug lenalidomide was evaluated in combination with rituximab for the frontline treatment of FL in the phase 3 RELEVANCE study. Ibrutinib, an oral Bruton tyrosine kinase inhibitor, is active in NHL and was evaluated in combination with lenalidomide, rituximab, and ibrutinib (IRR) in a phase 1 study. METHODS: The authors conducted an open-label, phase 2 clinical trial of IRR for previously untreated FL and MZL. The primary end point was progression-free survival (PFS) at 24 months. RESULTS: This study included 48 participants with previously untreated FL grade 1-3a (N = 38), or MZL (N = 10). Participants received 12, 28-day cycles of lenalidomide (15 mg, days 1-21 cycle 1; 20 mg, cycles 2-12), rituximab (375 mg/m2 weekly in cycle 1; day 1 cycles 2-12), and ibrutinib 560 mg daily. With a median follow-up of 65.3 months, the estimated PFS at 24 months was 78.8% (95% confidence interval [CI], 68.0%-91.4%) and 60-month PFS was 59.7% (95% CI, 46.6%-76.4%). One death occurred unrelated to disease progression. Grade 3-4 adverse events were observed in 64.6%, including 50% with grade 3-4 rash. CONCLUSIONS: IRR is highly active as frontline therapy for FL and MZL. Compared to historical results with lenalidomide and rituximab, PFS is similar with higher grade 3-4 toxicity, particularly rash. The study was registered with ClinicalTrials.gov (NCT02532257).

Patients with relapsed or refractory large B-cell lymphomas (rrLBCL) can achieve long-term remission after CD19 chimeric antigen receptor T-cell therapy (CART19). However, more than half of recipients will experience treatment failure. Thus, approaches are needed to identify high-risk patients who may benefit from alternative or consolidative therapy. We evaluated low-pass whole-genome sequencing (lpWGS) of cell-free DNA (cfDNA) before CART19 as a new approach for risk stratification. We performed lpWGS on pretreatment plasma samples from 122 patients at time of leukapheresis who received standard-of-care CART19 for rrLBCL to define DNA copy number alterations (CNAs). In multivariable selection, high focal CNA score (FCS) denoting genomic instability was the most significant pretreatment variable associated with inferior 3-month complete response rates (28% vs 56%, P = .0029), progression-free survival (PFS; P = .0007; hazard ratio, 2.11), and overall survival (OS; P = .0026; hazard ratio, 2.10). We identified 34 unique focal CNAs in 108 (89%) patients; of these, deletion 10q23.3 leading to loss of FAS death receptor was the most highly associated with poor outcomes, leading to inferior PFS (P < .0001; hazard ratio, 3.49) and OS (P = .0027; hazard ratio, 2.68). By combining FCS with traditional markers of increased tumor bulk (elevated lactate dehydrogenase and >1 extranodal site), we built a simple risk model that could reliably risk stratify patients. Thus, lpWGS of cfDNA is a minimally invasive assay that could rapidly identify high-risk patients and may guide patient selection for and targeted therapies to evaluate in future clinical trials.

Salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) is a potentially curative treatment for patients with relapsed or refractory large B-cell lymphoma (rrLBCL) with chemosensitive disease. A18 F-fluorodeoxyglucose positron emission tomography (PET) scan after salvage chemotherapy is used to assess response and eligibility for ASCT, but metrics for chemosensitivity in patients with residual disease are not well defined. We performed a single-centre retrospective analysis of 92 patients with a partial response or stable disease after salvage chemotherapy for rrLBCL who received ASCT to investigate PET-derived parameters and their prognostic utility. The Deauville 5-point Scale (D-5PS) score, maximum standardised uptake value (SUVmax ), total metabolic tumour volume (TMTV), and total lesion glycolysis (TLG) were calculated from the post-salvage/pre-ASCT PET scan. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 40% and 54% respectively. A D-5PS score of 5 (p = 0.0082, hazard ratio [HR] 2.09), high SUVmax (p = 0.0015, HR 2.48), TMTV (p = 0.035, HR 1.83) and TLG (p = 0.0036, HR 2.27) were associated with inferior PFS. A D-5PS score of 5 (p = 0.030, HR 1.98) and high SUVmax (p = 0.0025, HR 2.55) were associated with inferior OS. PET-derived parameters may help prognosticate outcomes after ASCT in patients with rrLBCL with residual disease after salvage chemotherapy.

BACKGROUND: Induction with ibrutinib and rituximab provides an opportunity to minimise chemotherapy exposure, because upfront use of these targeted therapies could result in remission without chemotherapy and allow for consolidation with only four cycles of chemotherapy instead of the conventional eight. We aimed to determine the activity and safety of ibrutinib-rituximab induction followed by shortened chemoimmunotherapy (four cycles) with rituximab plus hyper-fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (R-HCVAD) alternating with methotrexate-cytarabine in previously untreated patients with mantle cell lymphoma. METHODS: We did a single-centre, single-arm, phase 2 trial in previously untreated patients with mantle cell lymphoma. Eligible patients were aged 65 years or younger and had serum bilirubin of less than 1·5 mg/dL, creatinine clearance of 30 mL/min or more, Eastern Cooperative Oncology Group performance status of 2 or less, and cardiac ejection fraction 50% or more by echocardiogram. Patients received 12 cycles of ibrutinib-rituximab induction (part A; oral ibrutinib 560 mg daily and intravenous rituximab 375 mg/m2 weekly for the first 4 weeks and then on day 1 of cycles 3-12). As soon as patients had a complete response, four cycles of R-HCVAD alternating with methotrexate-cytarabine (part B) were administered. If they did not have a complete response or had a partial response, patients received two cycles of R-HCVAD alternating with methotrexate-cytarabine followed by reassessment, up to a total of eight cycles. Patients were taken off study if they had stable disease or progression during R-HCVAD. The primary outcome was the overall response rate after part A. The analyses were conducted on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT02427620. FINDINGS: 131 patients were enrolled between June 12, 2015, and Dec 6, 2018. The median age was 56 years (IQR 49-60). 58 (50%) of 117 patients had high Ki-67 (≥30%). 129 (98%, 95% CI 95-100) of 131 patients had an overall response in part A. The most common grade 3-4 adverse events were lymphocytopenia (19 [14%] of 131), skin rash (16 [12%]), thrombocytopenia (12 [9%]), infections (11 [8%]), and fatigue (ten [8%]) in part A and lymphocytopenia (96 [73%]), leukocytopenia (42 [32%]), thrombocytopenia (40 [30%]), and neutropenia (26 [20%]) in part B. There was one on-study death, which was not deemed to be treatment-related. INTERPRETATION: Induction with ibrutinib-rituximab in the frontline treatment of young patients with mantle cell lymphoma is active and safe. This approach allowed minimisation of the number of chemotherapy cycles, thereby reducing the adverse events associated with chemotherapy. Newer trials bringing the next-generation Bruton's tyrosine kinase inhibitors into the frontline setting might obviate the need for chemotherapy altogether in patients with mantle cell lymphoma.

Chimeric antigen receptor (CAR) T-cell therapy targeting CD19 may be associated with long-term adverse effects such as cytopenia and immune deficiency. In order to characterize these late events, we analyzed 31 patients with relapsed or refractory large B-cell lymphoma treated with axicabtagene ciloleucel at our institution on two clinical trials, ZUMA-1 (clinicaltrials gov. Identifier: NCT02348216) and ZUMA-9 (clinicaltrials gov. Identifier: NCT03153462). Complete blood counts, lymphocyte subsets, and immunoglobulin levels were measured serially until month 24 or progression. Fifteen (48%) patients had grade 3-4 cytopenia, including anemia (five, 16%), neutropenia (nine, 29%), or thrombocytopenia (13, 42%) at day 30. Cytopenia at day 30 was not significantly associated with later diagnosis of myelodysplasia. Among patients with ongoing remission, grade 3-4 cytopenia was observed in one of nine (11%) at 2 years. While peripheral CD8+ T cells recovered early, CD4+ T-cell recovery was delayed with a count of <200/mL in three of nine (33%) patients at 1 year and two of seven (29%) at 2 years. Immunoglobulin G levels normalized in five of nine (56%) patients at 2 years. Thirteen (42%) patients developed grade 3-4 infectious complications, including herpes zoster and Pneumocystis jiroveci pneumonia. These results suggest the need for prolonged monitoring and prophylaxis against opportunistic infections in these patients, to improve the longterm safety of axicabtagene ciloleucel therapy.

BACKGROUND: Patients with multicentric Castleman disease (MCD) who are negative for human immunodeficiency virus and human herpesvirus 8 are considered to have idiopathic MCD (iMCD). The clinical presentation of iMCD varies from mild constitutional symptoms to life-threatening symptoms or death. The treatment strategy varies from "watchful waiting" to high-dose chemotherapy. This diverse clinical presentation calls for a classification stratification system that takes into account the severity of the disease. SUBJECTS, MATERIALS, AND METHODS: We analyzed the clinical, laboratory, and pathologic abnormalities and treatment outcomes of 176 patients with iMCD (median follow-up duration 12 years) from the U.S. and China to better understand the characteristics and prognostic factors of this disease. This discovery set of iMCD results was confirmed from the validation set composed of additional 197 patients with iMCD organized from The International Castleman Disease Consortium. RESULTS: Using these data, we proposed and validated the iMCD international prognostic index (iMCD-IPI), which includes parameters related to patient characteristics (age > 40 years), histopathologic features (plasma cell variant), and inflammatory consequences of iMCD (hepatomegaly and/or splenomegaly, hemoglobin <80 g/L, and pleural effusion). These five factors stratified patients according to their performance status and extent of organ dysfunction into three broad categories: low risk, intermediate risk, and high risk. The iMCD-IPI score accurately predicted outcomes in the discovery study cohort, and the results were confirmed on the validation study cohort. CONCLUSION: This study represents the largest series of studies on patients with iMCD in the field and proposed a novel risk-stratification model for iMCD-IPI that could be used to guide risk-stratified treatment strategies in patients with iMCD. IMPLICATIONS FOR PRACTICE: Patients with idiopathic multicentric Castleman disease (iMCD) can benefit from care based on clinical symptoms and disease severity. This study in 176 patients with iMCD constructed an iMCD-IPI score based on five clinical factors, including age >40 years, plasmacytic variant subtype, hepatomegaly and/or splenomegaly, hemoglobin <80 g/L, and pleural effusion, and stratified patients into three risk categories: low risk, intermediate risk, and high risk. The predictive value was validated in an independent set of 197 patients with iMCD from The International Castleman Disease Consortium. The proposed novel model is valuable for predicting clinical outcome and selecting optimal therapies using clinical parameters.

The impact of pre-treatment maximum standardized uptake value (SUVmax) on the outcome of follicular lymphoma (FL) following specific frontline regimens has not been explored. We performed a retrospective analysis of 346 patients with advanced stage follicular lymphoma (FL) without histological evidence of transformation, and analyzed the impact of SUVmax on outcome after frontline therapy. Fifty-two (15%) patients had a SUVmax >18, and a large lymph node ≥6 cm was the only factor associating with SUVmax >18 on multivariate analysis (odds ratio 2.7, 95% confidence interval [CI]: 1.3-5.3, P=0.006). The complete response rate was significantly lower among patients treated with non-anthracycline-based regimens if SUVmax was >18 (45% vs 92%, P<0.001), but not among patients treated with R-CHOP (P=1). SUVmax >18 was associated with significantly shorter progression-free survival among patients treated with non-anthracycline-based regimens (77 months vs. not reached, P=0.02), but not among patients treated with R-CHOP (P=0.73). SUVmax >18 associated with shorter overall survival (OS) both in patients treated with R-CHOP (8-year OS 70% vs. 90%, P=0.02) and non-anthracycline-based frontline regimens (8-year OS 50% vs 85%, P=0.001). In conclusion, pre-treatment PET scan has prognostic and predictive value in patients with advanced stage FL receiving frontline treatment.

We analyzed 186 patients with lymphoma who underwent allogeneic stem cell transplantation (ASCT) with fludarabine-melphalan (FM) conditioning and different types of donors (25 haploidentical [HD], 98 matched unrelated [MUD], and 63 matched related [MRD]) at our institution between September 2009 and January 2018. Patients received fludarabine 160 mg/m2 (40 mg/m2/day for 4 days) in combination with 1 dose of melphalan 140 mg/m2 (FM140) or 100 mg/m2 (FM100). Engraftment was similar among the 3 groups (92%, 89%, and 98%, respectively; P = .7). The 6-month cumulative incidence of grade III-IV acute graft-versus-host disease (GVHD) was 4% in the HD group, 14% in the MUD group, and 8% in the MRD group (P not significant), and the respective 3-year cumulative incidence of chronic GVHD was 5%, 16%, and 26% (P not significant). The respective 3-year nonrelapse mortality and relapse rates were 31%, 32%, and 10% (HD versus MUD, P = .9; HD versus MRD, P = .02) and 15%, 21%, and 39% (HD versus MUD, P = .4; HD versus MRD, P = .04). At 3 years, progression-free survival (PFS) was 59%, 44%, and 46% (P not significant); overall survival (OS) was 52%, 54%, and 67% (P not significant); and GVHD-free, relapse-free survival was 39%, 31%, and 24% (P not significant). No differences in the 3-year PFS (57% versus 43%; Pâ¯=â¯.3) and OS (64% versus 58%; Pâ¯=â¯.7) were seen between patients receiving FM100 and those receiving FM140. Our data demonstrate that in patients with lymphoma, ASCT with HD transplants have similar outcomes as ASCT with HLA-matched transplants, and the FM100 conditioning regimen appears to be at least as effective as the FM140 regimen.

In a prospective phase II trial, pentostatin combined with cyclophosphamide and rituximab (PCR) induced strong responses and was well-tolerated in previously untreated patients with advanced-stage, indolent non-Hodgkin lymphoma (iNHL). After a median patient follow-up of more than 108 months, we performed an intent-to-treat analysis of our 83 participants. Progression-free survival (PFS) rates at 108 months for follicular lymphoma (FL), marginal zone lymphoma (MZL) and small lymphocytic lymphoma (SLL) were 71%, 67% and 15%, respectively, and were affected by clinicopathological characteristics. Ten-year PFS rates for those with beta-2-microglobulin levels <2·2 and ≥2·2 mg/l prior to treatment were 71% and 21%, respectively. Patients without bone marrow involvement had 10-year PFS rates of 72% vs. 29% for those with involvement. At time of analysis, the median overall survival (OS) had not been reached. The OS rate was 64% at 10 years and differed significantly based on histology: 94% for FL, 66% for MZL and 39% for SLL. Long-term toxicities included 18 (21·7%) patients with second malignancies and 2 (2·4%) who developed myelodysplastic syndrome after receiving additional lines of chemotherapy. Our 10-year follow-up analysis confirms that PCR is an effective, robust and tolerable treatment regimen for patients with iNHL.

Lack of consensus for first-line marginal zone lymphoma (MZL) treatment and toxicities associated with currently available systemic therapies have inspired evaluation of immunotherapeutic agents yielding robust outcomes with improved tolerability. We previously reported durable efficacy with first-line lenalidomide and rituximab (R2 ) in follicular lymphoma, MZL and small lymphocytic lymphoma with a subsequent long-term follow-up shown here in MZL patients. This phase 2 investigator-initiated study included previously untreated, stage III/IV MZL patients treated with lenalidomide 20 mg/day on days 1-21 and rituximab 375 mg/m2 on day 1 of each 28-day cycle, continuing in responders for ≥6-12 cycles. The primary endpoint was overall response rate (ORR); secondary endpoints were complete and partial response (CR, PR), safety, and progression-free survival (PFS). The ORR was 93% with 70% attaining CR/CR unconfirmed. At median follow-up of 75·1 months, median PFS was 59·8 months and 5-year OS was 96%. Most non-haematological adverse events (AE) were grade 1/2. Grade 3 haematological AEs were neutropenia (33%) and leucopenia (7%), and grade 4 were leucopenia (3%) and thrombocytopenia (3%). Two patients died of secondary malignancies; no treatment-related fatalities occurred. With extended follow-up, outcomes for MZL patients receiving R2 were robust with no unexpected late or delayed toxicities.

PURPOSE: The authors examined the prevalence of a histologic change of ocular adnexal lymphoma (OAL) grade in patients with a history of lymphoma in nonocular sites. METHODS: In this retrospective study, the authors reviewed the clinical and pathological data of 209 patients with OAL treated by the senior author during 2000 to 2017. RESULTS: Of 209 patients with OAL, 65 (31%) had a history of lymphoma. In 54 of the 65 patients (83%), the original lymphoma and OAL were of the same histologic type. In 8 of the 65 patients (12.3%), the OAL was more indolent than the original lymphoma: 6 patients with a history of diffuse large B-cell lymphoma, one of mantle cell lymphoma, and one of grade 3 follicular lymphoma had biopsy-proven extranodal marginal-zone lymphoma in the orbital area. Two additional patients (3%) with a history of chronic lymphocytic leukemia developed OAL: diffuse large B-cell lymphoma in one patient and extranodal marginal-zone lymphoma in the other. One patient (1.5%) with a history of a low-grade follicular lymphoma relapsed as a different low-grade histology of extranodal marginal-zone lymphoma. Lower-grade OAL than the original lymphoma was more common than higher-grade OAL than the original lymphoma (p = 0.048). CONCLUSIONS: In this cohort of 209 patients with OAL, the authors found that nearly one third had a history of lymphoma, 17% of whom had a different histologic type of lymphoma in the orbit, more commonly a more indolent type. This underscores the importance of biopsy of OAL even in patients with a known history of lymphoma to determine the histologic subtype of orbital lymphoma and to help guide appropriate treatment.

To determine whether pre-treatment neutrophil/lymphocyte (NLR) or platelet/lymphocyte ratios (PLR) are predictive for progression in early-stage classical Hodgkin lymphoma (cHL), we derived NLR and PLR values for 338 stage I/II cHL patients and appropriate cut-off point values to define progression. Two-year freedom from progression (FFP) for patients with NLR ≥6·4 was 82·2% vs. 95·7% with NLR <6·4 (P < 0·001). Similarly, 2-year FFP was 84·3% for patients with PLR ≥266·2 vs. 96·1% with PLR <266·2 (P = 0·003). On univariate analysis, both NLR and PLR were significantly associated with worse FFP (P = 0·001). On multivariate analysis, PLR remained a significant, independent prognostic factor (P < 0·001).

We report a single-centre, randomized study evaluating the efficacy and safety of concurrent fludarabine, mitoxantrone, dexamethasone (FND) and rituximab versus sequential FND followed by rituximab in 158 patients with advanced stage, previously untreated indolent lymphoma, enrolled between 1997 and 2002. Patients were randomized to 6-8 cycles of FND followed by 6 monthly doses of rituximab or 6 doses of rituximab given concurrently with FND. All patients who achieved at least a partial response received 12 months of interferon (IFN) maintenance. Median ages were 54 and 55 years. The two groups were comparable with the exception of a higher percentage of females (65% vs. 43%) and baseline anaemia (23% vs. 11%) in the FND followed by rituximab group. Complete response/unconfirmed complete response rates were 89% and 93%. The most frequent grade ≥ 3 toxicity was neutropenia (86% vs. 96%). Neutropenic fever occurred in 21% and 16%. Late toxicity included myelodysplastic syndrome (n = 3) and acute myeloid leukaemia (n = 5). With 12·5 years of follow-up, no significant differences based on treatment schedule were observed. 10-year overall survival estimates were 76% and 73%. 10-year progression-free survival estimates were 52% and 51%. FND with concurrent or sequential rituximab, and IFN maintenance in indolent lymphoma demonstrated high response rates and robust survival.

Survival outcome of patients with peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) and angioimmunoblastic T-cell lymphoma (AITL) who experience disease progression/relapse remains very poor. A total of 321 patients, newly diagnosed with PTCL-NOS (n = 180) or AITL (n = 141) between 1999 and 2015, were analysed. Failure-free survival (FFS) and overall survival (OS) were calculated from the time of first disease progression (FFS1, OS1), from second disease progression (FFS2, OS2) and from third progression (FFS3, OS3). With a median follow-up duration of 52 months, 240 patients (135 PTCL-NOS, 105 AITL) experienced progression/relapse. In patients with PTCL-NOS, the median durations of FFS1, FFS2 and FFS3 were 3·1, 2·5 and 2·1 months, respectively. In patients with AITL, they were 5·5, 2·9 and 2·3 months, respectively. There was no improvement in FFS1 and OS1 by the time of recurrence during this period (1999-2004, 2005-2009 and 2010-2015). The median FFS after pralatrexate and romidepsin was only 3·0 and 2·5 months, respectively. The 5-year OS rates after salvage autologous and allogeneic transplant were 32% and 52%, respectively; while the 5-year OS rates for patients who did not undergo transplant was 10%. Further research for novel therapeutic approaches with higher efficacy and better safety profile are needed.

BACKGROUND: Relapsed or refractory mantle cell lymphoma (MCL) has a poor prognosis. The best outcome is achieved in patients who have a partial or complete response to salvage treatment and proceed to allogeneic stem cell transplant. PATIENTS AND METHODS: Twenty-one patients were given a combination regimen of bortezomib, cyclophosphamide, and rituximab at MD Anderson Cancer Center as part of a single-arm, prospective, open-label phase II clinical trial. The median age was 66 years, with a median number of prior treatments of three. Sixty-seven percent had failed intensive chemoimmunotherapy and 43% were intermediate/high risk according to the MCL international prognostic index score, with a median Ki-67 proliferation index of 45% in those who were tested. RESULTS: The rates of overall and complete response achieved were 74% and 42%, respectively, with median progression-free and overall survivals of 9 months and 36.4 months, respectively. The regimen's toxicity profile was acceptable; only 25% of the cycles resulted in grade 3 or 4 neutropenia or thrombocytopenia, and only 3% of cycles produced grade 3-4 fatigue. There were no episodes of grade 3-4 neuropathy. CONCLUSION: The combination of bortezomib with cyclophosphamide and rituximab is an effective and well-tolerated regimen in patients with relapsed/refractory MCL. Because of its low toxicity, future combinations of this regimen with other promising drugs that have different mechanisms of action offer a realistic possibility that may improve outcomes for patients who have MCL. The Oncologist 2017;22:549-553 IMPLICATIONS FOR PRACTICE: The combination of bortezomib with cyclophosphamide and rituximab represents an additional effective novel salvage regimen for mantle cell lymphoma. This combination adds to the growing list of treatment options available for patients with mantle cell lymphoma.

PURPOSE: The aim of this study was to determine rates of positive findings on positron emission tomography (PET) and bone marrow biopsy performed during staging workup for ocular adnexal lymphoma (OAL). METHODS: A retrospective review of OAL patients was conducted. Demographics, primary versus secondary OAL, histologic subtype, and findings on PET and bone marrow biopsy performed as part of the initial staging workup for OAL were recorded. RESULTS: The study included 119 patients with OAL. There were 85 primary and 34 secondary OALs. The main histologic subtypes of lymphoma were mucosa-associated lymphoid tissue (n = 61), follicular (n = 26), diffuse large B-cell (n = 17), and mantle cell (n = 10). Positive PET findings were seen in 42 of 68 patients (62%) with primary OAL and 19 of 24 (79%) with secondary OAL. Positive PET findings were seen in 24 of 47 patients (51%) with mucosa-associated lymphoid tissue, 13 of 17 (76%) with follicular, 14 of 15 (93%) with diffuse large B-cell, and 9 of 10 (90%) with mantle cell lymphoma. Positive findings on bone marrow biopsy were seen in 7 of 59 patients (12%) with mucosa-associated lymphoid tissue, 4 of 23 (17%) with follicular, 1 of 17 (6%) with diffuse large B-cell, and 2 of 9 (22%) with mantle cell lymphoma. CONCLUSIONS: Our findings suggest that a significant proportion of patients with primary and secondary OAL have positive findings on PET and bone marrow biopsy at initial diagnosis, suggesting a reasonable yield for these tests as part of the initial staging workup in patients with a new diagnosis of OAL.

BACKGROUND: The number of elderly patients with diffuse large B-cell lymphoma (DLBCL) in our aging society continues to rise, although the optimal management of very elderly patients with DLBCL is unknown. METHODS: This study evaluated 207 patients who were 80 years old or older at the diagnosis of DLBCL from 2002 to 2014 at The University of Texas MD Anderson Cancer Center. Analyzed features included clinical characteristics, treatment outcomes, and tolerability of therapy. Cox proportional hazards models examined relations between the treatment regimen and survival. RESULTS: The median age was 83 years (range, 80-96 years). Fifty-four percent of the patients had intermediate- to high-risk or high-risk International Prognostic Index scores. Fifteen percent had scores of 4 or higher on the Charlson Comorbidity Index (CCI). The initial therapies included rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; 70%); rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (R-EPOCH; 6%); and non-anthracycline-based therapies, including rituximab, cyclophosphamide, etoposide, vincristine, and prednisone (R-CEOP) and rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP; 10%). With a median follow-up of 38.1 months, the 3-year failure-free survival (FFS) and overall survival (OS) rates were 55% and 54%, respectively. Eighty-eight patients experienced relapse during the follow-up, but only 3 patients (3.4%) experienced relapse beyond 3 years. Patients who received R-CHOP or R-EPOCH had significantly longer FFS than those who received R-CEOP or R-CVP, with 3-year FFS rates of 63% for R-CHOP, 74% for R-EPOCH, and 23% for R-CEOP and R-CVP. Male sex, a monocyte count ≥ 500 × 107 /L, and a CCI score ≥ 4 were significantly associated with inferior OS. Extranodal disease (≥2) and a higher CCI score were associated with a high risk of treatment-related mortality. CONCLUSIONS: With anthracycline-based regimens such as R-CHOP and R-EPOCH, very elderly patients with DLBCL had superior outcomes similar to those achieved for younger patients with DLBCL.

Intensive chemotherapy regimens containing cytarabine have substantially improved remission durability and overall survival in younger adults with mantle cell lymphoma (MCL). However, there have been no long-term follow-up results for patients treated with these regimens. We present long-term survival outcomes from a pivotal phase II trial of rituximab, hyper-fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternating with methotrexate and cytarabine (R-HCVAD/MA). At 15 years of follow-up (median: 13·4 years), the median failure-free survival (FFS) and overall survival (OS) for all patients was 4·8 years and 10·7 years, respectively. The FFS seems to have plateaued after 10 years, with an estimated 15-year FFS of 30% in younger patients (≤65 years). Patients who achieved complete response (CR) after 2 cycles had a favourable median FFS of 8·8 years. Six patients developed myelodysplastic syndrome/acute myeloid leukaemia (MDS/AML) whilst in first CR. The 10-year cumulative incidence of MDS/AML of patients in first remission was 6·2% (95% confidence interval: 2·5-12·2%). In patients with newly diagnosed MCL, R-HCVAD/MA showed sustained efficacy, with a median OS exceeding 10 years in all patients and freedom from disease recurrence of nearly 15 years in almost one-third of the younger patients (≤65 years).

There are limited reports that baseline peripheral absolute neutrophil count (ANC), absolute monocyte count (AMC), absolute lymphocyte count (ALC) and serum ß2-microglobulin level independently predict survival in patients with diffuse large B-cell lymphoma (DLBCL). To confirm these findings, we analysed these parameters together with components of the International Prognostic Index (IPI) in patients with newly-diagnosed DLBCL. We evaluated baseline clinical features for their ability to predict survival in 817 newly diagnosed, previously untreated patients with DLBCL who received frontline treatments between October 2001 and December 2011. The median age at diagnosis was 58 years. Multivariate analysis identified elevated baseline ANC (P = 0·036), AMC (P = 0·028) and serum ß2-microglobulin level (P < 0·001), poor performance status (P < 0·001) and high number of extranodal disease sites (P = 0·0497) as independent unfavourable predictors of OS; serum ß2-microglobulin level was the strongest predictor of survival outcomes among all the parameters. High baseline serum ß2-microglobulin, ANC and AMC levels are independent prognostic factors for short overall survival in patients with newly diagnosed DLBCL. Our new model, based on the above five parameters, better stratifies patients into various risk categories than the IPI for newly diagnosed DLBCL.
