Prolonged in-hospital stay and higher mortality after Covid-19 among patients with non-Hodgkin lymphoma treated with B-cell depleting immunotherapy.

Prolonged Covid-19 is an emerging issue for patients with lymphoma or immune deficiency. We aimed to examine prolonged length of in-hospital stay (LOS) due to Covid-19 among patients with lymphoma and assess its determinants and outcomes. Adult patients with lymphoma admitted for Covid-19 to 16 French hospitals in March and April, 2020 were included. Length of in-hospital stay was analyzed as a competitor vs death. The study included 111 patients. The median age was 65 years (range, 19-92). Ninety-four patients (85%) had B-cell non-Hodgkin lymphoma. Within the 12 months prior to hospitalization for Covid-19, 79 patients (71%) were treated for their lymphoma. Among them, 63 (57%) received an anti-CD20 therapy. Fourteen patients (12%) had relapsed/refractory disease. The median LOS was 14 days (range, 1-235). After a median follow-up of 191 days (3-260), the 6-month overall survival was 69%. In multivariable analyses, recent administration of anti-CD20 therapy was associated with prolonged LOS (subdistribution hazard ratio 2.26, 95% confidence interval 1.42-3.6, p < 0.001) and higher risk of death (hazard ratio 2.17, 95% confidence interval 1.04-4.52, p = 0.039). An age ≥ 70 years and relapsed/refractory lymphoma were also associated with prolonged LOS and decreased overall survival. In conclusion, an age ≥ 70 years, a relapsed/refractory lymphoma and recent administration of anti-CD20 therapy are risk factors for prolonged LOS and death for lymphoma patients hospitalized for Covid-19. These findings may contribute to guide the management of lymphoma during the pandemic, support evaluating specific therapeutic approaches, and raise questions on the efficacy and timing of vaccination of this particular population.

Determinants of outcome in Covid-19 hospitalized patients with lymphoma: A retrospective multicentric cohort study.

BACKGROUND: Patients with lymphoma are immunocompromised because of the disease per se and its treatments. We aimed to describe the characteristics of patients with lymphoma hospitalized for Coronavirus Disease 2019 (Covid-19) and to analyze pre-Covid-19 determinants of mortality. METHODS: This retrospective multicentric cohort study used the Programme de Médicalisation des Systèmes d'Information database to identify all adult patients with lymphoma, hospitalized for Covid-19 in March and April 2020, in 12 hospitals of three French regions with pandemic outbreaks. The characteristics of lymphoma and Covid-19 were collected from medical charts. FINDINGS: Eighty-nine patients were included. The median age was 67 years (range, 19-92), 66% were male and 72% had a comorbidity. Most patients had B-cell non-Hodgkin lymphoma (86%) and had received a lymphoma treatment within one year (70%). With a median follow-up of 33 days from admission, 30-day overall survival was 71%, (95% confidence interval, 62-81%). In multivariable analysis, having an age ≥ 70 years (hazard ratio 2·87, 1·20-6·85, p = 0·02) and relapsed/refractory lymphoma (hazard ratio 2·54, 1·14-5·66, p = 0·02) were associated with mortality. Recent bendamustine treatment (n = 9) was also pejorative (hazard ratio 3·20, 1·33-7·72, p = 0·01), but was strongly associated with relapsed/refractory lymphoma. Remarkably, 30-day overall survival for patients < 70 years of age without relapsed/refractory lymphoma was 88% (78% - 99%). INTERPRETATION: Thirty-day mortality was associated with being older and relapsed/refractory lymphoma. Survival of patients younger than 70 years without relapsed/refractory lymphoma was comparable to that of the general population. FUNDING: There have been no specific funds to run this study.

ABVD or BEACOPPbaseline along with involved-field radiotherapy in early-stage Hodgkin Lymphoma with risk factors: Results of the European Organisation for Research and Treatment of Cancer (EORTC)-Groupe d'Étude des Lymphomes de l'Adulte (GELA) H9-U intergroup randomised trial.

PURPOSE: For early-stage Hodgkin lymphoma (HL), optimal chemotherapy regimen and the number of cycles to be delivered remain to settle down. The H9-U trial compared three modalities of chemotherapy followed by involved-field radiotherapy (IFRT) in patients with stage I-II HL and risk factors (NCT00005584). PATIENTS AND METHODS: Patients aged 15-70 years with untreated supradiaphragmatic HL with at least one risk factor (age ≥ 50, involvement of 4-5 nodal areas, mediastinum/thoracic ratio ≥ 0.35, erythrocyte sedimentation rate (ESR) ≥ 50 without B-symptoms or ESR ≥ 30 and B-symptoms) were eligible for the randomised, open label, multicentre, non-inferiority H9-U trial. The limit of non-inferiority was set at 10% for the difference between 5-year event-free survival (EFS) estimates. From October 1998 to September 2002, 808 patients were randomised to receive either the control arm 6-ABVD-IFRT (n = 276), or one of the two experimental arms: 4-ABVD-IFRT (n = 277) or 4-BEACOPPbaseline-IFRT (n = 255). RESULTS: Results in the 4-ABVD-IFRT (5-year EFS, 85.9%) and the 4-BEACOPPbaseline-IFRT (5-year EFS, 88.8%) were not inferior to 6-ABVD-IFRT (5-year EFS, 89.9%): difference of 4.0% (90%CI, -0.7%-8.8%) and of 1.1% (90%CI,-3.5%-5.6%) respectively. The 5-year overall survival estimates were 94%, 93%, and 93%, respectively. Patients treated with combined modality treatment chemotherapeutic regimen comprising doxorubicin (Adriamycin), bleomycin, vincristine (Oncovin), cyclophosphamide, procarbazine, etoposide and prednisone (BEACOPP)baseline more often developed serious adverse events requiring supportive measures and hospitalisation compared with patients receiving the chemotherapeutic regimen comprising doxorubicin (Adriamycin), bleomycin, vinblastine and dacarbazine (ABVD). CONCLUSIONS: The trial demonstrates that 4-ABVD followed by IFRT yields high disease control in patients with early-stage HL and risk factors responding to chemotherapy. Although non-inferior in terms of efficacy, four cycles of BEACOPPbaseline were more toxic than four or six cycles of ABVD.

Combination of ofatumumab and reduced-dose CHOP for diffuse large B-cell lymphomas in patients aged 80 years or older: an open-label, multicentre, single-arm, phase 2 trial from the LYSA group.

BACKGROUND: In 2011 we reported a rituximab plus miniCHOP (reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone) combination for patients older than 80 years with diffuse large B-cell lymphoma (DLBCL). The 2-year overall survival was 59% (95% CI 49-67) with an excess of early toxicity. To improve those results we tested the same chemotherapy protocol in combination with ofatumumab and a pre-phase treatment. METHODS: For this open-label, multicentre, single-group, phase 2 trial, we recruited patients older than 80 years with untreated histologically-proven CD20-positive DLBCL, Ann Arbor stage I to IV, from 41 academic and hospital centres in France and Belgium. Patients received a pre-phase with oral vincristine (1 mg total dose 1 week before cycle 1 [day -7]) and oral prednisone (60 mg total dose starting 1 week before cycle 1, for 4 days [day -7 to day -4]) before the first cycle of the ofatumumab plus miniCHOP regimen. The regimen consisted of 1000 mg total dose of intravenous ofatumumab, 25 mg/m2 of intravenous doxorubicin, 400 mg/m2 of intravenous cyclophosphamide, and 1 mg of intravenous vincristine, on day 1 of each cycle; and 40 mg/m2 of oral prednisone on days 1-5. Ofatumumab was administered with 1000 mg of paracetamol and 50 mg of diphenhydramine. The primary endpoint was overall survival in the intention-to-treat population. The statistical analysis has been done on an intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT01195714. FINDINGS: Between June 2, 2010, and Nov 4, 2011, we enrolled 120 patients. Age-adjusted International Prognostic Index was 2-3 in 68 (57%) of them. The median follow-up time was 26·8 months (IQR 24·5-30·1). The 2-year overall survival was 64·7% (95% CI 55·3-72·7) and median overall survival was not reached (95% CI 30·2-not reached). 45 patients died during the treatment, of whom 28 (62%) died due to lymphoma. The most common side-effect was haematological toxicity. Among the 120 patients, grade 3-4 neutropenia was reported in 24 (21%) patients and thrombocytopenia in two (2%), during the treatment period. Grade 3-4 anaemia was reported in six (5%) patients; seven (6%) patients had one episode of febrile neutropenia. 17 (15%) of 115 patients in the modified intention-to-treat population had red blood cell transfusions and three (3%) had platelet transfusions. INTERPRETATION: Our result suggest that, in patients older than 80 years with DLBCL, ofatumumab and pre-phase treatment seem to improve overall survival compared with the previously reported data. The combination of pre-phase treatment, a monoclonal antibody against CD20, and miniCHOP can be considered a new treatment platform for use in randomised clinical trial design for DLBCL treatment in patients older than 80 years.

Eight Cycles of ABVD Versus Four Cycles of BEACOPPescalated Plus Four Cycles of BEACOPPbaseline in Stage III to IV, International Prognostic Score ≥ 3, High-Risk Hodgkin Lymphoma: First Results of the Phase III EORTC 20012 Intergroup Trial.

PURPOSE: To compare patients with high-risk stage III to IV Hodgkin lymphoma (HL) in the phase III European Organisation for Research and Treatment of Cancer 20012 Intergroup trial (Comparison of Two Combination Chemotherapy Regimens in Treating Patients With Stage III or Stage IV Hodgkin's Lymphoma) who were randomly assigned to either doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or to bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP). PATIENTS AND METHODS: Patients with clinical stage III or IV HL, International Prognostic Score of 3 or higher, and age 60 years or younger received ABVD for eight cycles (ABVD8) or escalated-dose BEACOPP (BEACOPPescalated) for four cycles followed by baseline BEACOPP (BEACOPPbaseline) for four cycles (BEACOPP4+4) without radiotherapy. Primary end points were event-free survival (EFS), treatment discontinuation, no complete response (CR) or unconfirmed complete response (CRu) after eight cycles, progression, relapse, or death. Secondary end points were CR rate, overall survival (OS), quality of life, secondary malignancies, and disease-free survival in CR/CRu patients. RESULTS: Between 2002 and 2010, 549 patients were randomly assigned to ABVD8 (n = 275) or BEACOPP4+4 (n = 274). Other characteristics included median age, 35 years; male, 75%; stage IV, 74%; "B" symptoms, 81%; and International Prognostic Score ≥ 4, 59%. WHO performance status was 0 (34%), 1 (48%), or 2 (17%). Median follow-up was 3.6 years. CR/CRu was 82.5% in both arms. At 4 years, EFS was 63.7% for ABVD8 versus 69.3% for BEACOPP4+4 (hazard ratio [HR], 0.86; 95% CI, 0.64 to 1.15; P = .312); disease-free survival was 85.8% versus 91.0% (HR, 0.59; 95% CI, 0.33 to 1.06; P = .076), and OS was 86.7% versus 90.3% (HR, 0.71; 95% CI, 0.42 to 1.21; P = .208). Death as a result of toxicity occurred in six and five patients, early discontinuation (before cycle 5) in 12 and 26 patients, treatment crossovers in five and 10 patients, and secondary malignancies in eight and 10 patients in the ABVD8 and BEACOPP4+4 arms, respectively. CONCLUSION: ABVD8 and BEACOPP4+4 resulted in similar EFS and OS in patients with high-risk advanced-stage HL. Because BEACOPP4+4 did not demonstrate a favorable effectiveness or toxicity ratio compared with ABVD8, treatment burden, immediate and late toxicities, and associated costs must be considered before selecting one of these regimens on which to build future treatment strategies.

Personalized risk prediction for event-free survival at 24 months in patients with diffuse large B-cell lymphoma.

We recently defined event-free survival at 24 months (EFS24) as a clinically relevant outcome for patients with DLBCL. Patients who fail EFS24 have very poor overall survival, while those who achieve EFS24 have a subsequent overall survival equivalent to that of the age- and sex-matched general population. Here, we develop and validate a clinical risk calculator (IPI24) for EFS24. Model building was performed on a discovery dataset of 1,348 patients with DLBCL and treated with anthracycline-based immunochemotherapy. A multivariable model containing age, Ann Arbor stage, normalized serum LDH, ALC, ECOG performance status, bulky disease, and sex was identified. The model was then applied to an independent validation dataset of 1,177 DLBCL patients. The IPI24 score estimates the probability of failing to achieve the EFS24 endpoint for an individual patient. The IPI24 model showed superior discriminatory ability (c-statistic = 0.671) in the validation dataset compared to the IPI (c-statistic = 0.649) or the NCCN-IPI (c-statistic = 0.657). After recalibration of the model on the combined dataset, the median predicted probability of failing to achieve EFS24 was 36% (range, 12-88%), and the IPI24 showed an EFS24 gradient in all IPI groups. The IPI24 also identified a significant percentage of patients with high risk disease, with over 20% of patients having a 50% or higher risk of failing to achieve EFS24. The IPI24 provides an individual patient level probability of achieving the clinically relevant EFS24 endpoint. It can be used via electronic apps.

Pediatric-Like Acute Lymphoblastic Leukemia Therapy in Adults With Lymphoblastic Lymphoma: The GRAALL-LYSA LL03 Study.

PURPOSE: This study evaluated the efficacy of pediatric-like acute lymphoblastic leukemia (ALL) therapy in adults with lymphoblastic lymphoma (LL). PATIENTS AND METHODS: This was a prospective phase II study in adults 18 to 59 years old with previously untreated LL. Patients were treated with an adapted pediatric-like ALL protocol, which included a corticosteroid prephase, a five-drug induction reinforced by sequential cyclophosphamide administration, dose-dense consolidation, late intensification, CNS prophylaxis, and a 2-year maintenance phase. Treatment response was assessed by computed tomography and optional positron emission tomography. Allogeneic hematopoietic stem cell transplant was offered to selected patients in first complete remission (CR) or unconfirmed CR. RESULTS: The study enrolled 148 patients (131 with T-lineage LL [T-LL] and 17 with B-lineage LL [B-LL]). A total of 119 patients with T-LL (90.8%) and 13 with B-LL (76.5%) reached CR/unconfirmed CR, including 26 with T-LL and two with B-LL who needed a second induction salvage course. Relapse occurred in 34 patients with T-LL and four with B-LL. In patients with T-LL, 3-year event-free survival was 63.3% (95% CI, 54.2% to 71.0%), disease-free survival was 72.4% (95% CI, 63.0% to 79.7%), and overall survival was 69.2% (95% CI, 60.0% to 76.7%). Multivariate analysis identified serum lactate dehydrogenase level and the NOTCH1/FBXW7/RAS/PTEN oncogene (a four-gene oncogenetic classifier) status but not positron emission tomography or hematopoietic stem cell transplant as independent prognostic factors for outcome in T-LL. CONCLUSION: In adults with LL, an intensive pediatric-like ALL treatment protocol was associated with a good response rate and outcome. In patients with T-LL, the four-gene oncogenetic classifier and lactate dehydrogenase level were independent prognostic indicators.

Nodular lymphocyte predominant Hodgkin lymphoma: a Lymphoma Study Association retrospective study.

Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320-1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234-0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

Rituximab plus gemcitabine and oxaliplatin in patients with refractory/relapsed diffuse large B-cell lymphoma who are not candidates for high-dose therapy. A phase II Lymphoma Study Association trial.

A previous pilot study with rituximab, gemcitabine and oxaliplatin showed promising activity in patients with refractory/relapsed B-cell lymphoma. We, therefore, conducted a phase II study to determine whether these results could be reproduced in a multi-institutional setting. This phase II study included 49 patients with refractory (n=6) or relapsing (n=43) diffuse large B-cell lymphoma. The median age of the patients was 69 years. Prior treatment included rituximab in 31 (63%) and autologous transplantation in 17 (35%) patients. International Prognostic Index at enrollment was >2 in 34 patients (71%). The primary endpoint was overall response rate after four cycles of treatment. Patients were planned to receive eight cycles if they reached at least partial remission after four cycles. After four cycles 21 patients (44%) were in complete remission and 8 (17%) in partial remission, resulting in an overall response rate of 61%. Factors significantly affecting overall response rate were early (<1 year) progression/relapse (18% versus 54%; P=0.001) and prior exposure to rituximab (23% versus 65%; P=0.004). Five-year progression-free and overall survival rates were 12.8% and 13.9%, respectively. Rituximab, gemcitabine and oxaliplatin were well tolerated with grade 3-4 infectious episodes in 22% of the cycles. These results are the first confirmation from a multicenter study that rituximab, gemcitabine and oxaliplatin provide a consistent response rate in patients with refractory/relapsed diffuse large B-cell lymphoma. This therapy can now be considered as a platform for new combinations with targeted treatments. This trial was registered at clinicaltrial.gov under #NCT00169195.

Dose-dense rituximab-CHOP compared with standard rituximab-CHOP in elderly patients with diffuse large B-cell lymphoma (the LNH03-6B study): a randomised phase 3 trial.

BACKGROUND: Immunochemotherapy with rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) has become the standard of care for elderly patients with diffuse large B-cell lymphoma. We aimed to ascertain if a dose-dense R-CHOP regimen administered every 2 weeks (R-CHOP14) was superior to the standard 3-week schedule (R-CHOP21). METHODS: We did a randomised phase 3 trial at 83 centres in four countries. 602 patients aged 60-80 years with untreated diffuse large B-cell lymphoma and at least one adverse prognostic factor (age-adjusted international prognostic index ≥ 1) were eligible for the study. We randomly allocated individuals to R-CHOP-ie, rituximab (375 mg/m(2)), cyclophosphamide (750 mg/m(2)), doxorubicin (50 mg/m(2)), vincristine (1.4 mg/m(2), up to 2 mg) all on day 1, and prednisone 40 mg/m(2) daily for 5 days-administered every 14 days (n=304) or every 21 days (n=298) for eight cycles. We did permuted-block randomisation (block size four, allocation ratio 1:1) stratified by centre and number of adverse prognostic factors. The primary endpoint was event-free survival. Our analysis was of the intention-to-treat population, and we present the final analysis. This study is registered with ClinicalTrials.gov, number NCT00144755. FINDINGS: Two patients allocated R-CHOP21 were ineligible for the study and were excluded from analyses. After median follow-up of 56 months (IQR 27-60), 3-year event-free survival was 56% (95% CI 50-62) in the R-CHOP14 group and 60% (55-66) in the R-CHOP21 group (hazard ratio 1.04, 95% CI 0.82-1.31; p=0.7614). Grade 3-4 neutropenia occurred in 224 (74%) of 304 patients allocated R-CHOP14 and 189 (64%) of 296 assigned R-CHOP21, despite increased use of granulocyte colony-stimulating factor in the R-CHOP14 group compared with the R-CHOP21 group. 143 (47%) patients in the R-CHOP14 group received at least one red-blood-cell transfusion versus 93 (31%) in the R-CHOP21 group (p=0.0001). 35 (12%) patients allocated R-CHOP14 received at least one platelet transfusion versus 25 (8%) assigned R-CHOP21 (p=0.2156). 155 (51%) patients who were assigned R-CHOP14 had at least one serious adverse event compared with 140 (47%) who were allocated R-CHOP21. INTERPRETATION: In elderly patients with untreated diffuse large B-cell lymphoma and at least one adverse prognostic factor, a 2-week dose-dense R-CHOP regimen did not improve efficacy compared with the 3-week standard schedule. The frequency of toxic side-effects was similar between regimens, but R-CHOP14 was associated with increased need for red-blood-cell transfusion.

Impact of rituximab on stem cell mobilization following ACVBP regimen in poor-risk patients with diffuse large B-cell lymphoma: results from a large cohort of patients.

BACKGROUND: The ACVBP regimen is an efficient induction regimen for poor-risk patients with diffuse large B-cell lymphoma (DLBCL) before consolidative autologous stem cell transplantation. Adjunction of the monoclonal anti-CD20 antibody rituximab (R-ACVBP) was recently found to be superior to ACVBP alone. This study assessed the impact of rituximab on stem cell mobilization in two similar consecutive groups of patients treated with ACVBP in two prospective, controlled trials. STUDY DESIGN AND METHODS: The first trial (LNH-98B-3) involved 137 patients treated with ACVBP alone. In the second trial (LNH-03-3B), 91 patients received an R-ACVBP regimen. Stem cell mobilization was performed after a course of (R)-ACVBP. RESULTS: The median peak numbers of blood CD34+ cell counts recorded before the first apheresis procedure in the ACVBP and R-ACVBP groups were 69×10(6) and 63×10(6) /L, respectively (p=0.55). The median numbers of CD34+ cells collected were 7.1×10(6) and 6.0×10(6) CD34+ cells/kg for the ACVBP and R-ACVBP groups, respectively (p=0.13). The median number of apheresis procedures required for gathering the minimum amount of CD34+ cells (2×10(6) /kg) was the same in the two groups. CONCLUSION: When compared with ACVBP alone, adjunction of rituximab does not impair stem cell mobilization.

Long-term outcome of adults with systemic anaplastic large-cell lymphoma treated within the Groupe d'Etude des Lymphomes de l'Adulte trials.

PURPOSE: Systemic anaplastic large-cell lymphoma (ALCL) is a T-cell lymphoma, whose anaplastic lymphoma kinase (ALK) expression varies according to age. Long-term outcomes of chemotherapy-treated adults are not definitively established and should be evaluated. PATIENTS AND METHODS: Patients treated in three Groupe d'Étude des Lymphomes de l'Adulte prospective clinical trials with confirmed systemic ALCL after immunohistopathologic review and defined ALK expression status were analyzed. RESULTS: Among the 138 adult patients with ALCL, 64 (46%) were ALK positive, and 74 (54%) were ALK negative. Median follow-up was 8 years. At diagnosis, significantly more patients younger than 40 years old were ALK positive than ALK negative (66% v 23%, respectively; P < .001). Comparing patients with ALK-positive and ALK-negative ALCL, ß(2)-microglobulin was ≥ 3 mg/L in 12% and 33% (P = .017); International Prognostic Index was high (score, 3 to 5) in 23% and 48% (P = .03); complete response rates to first-line treatment were 86% and 68% (P = .01); and 8-year overall survival (OS) rates were 82% (95% CI, 69% to 89%) and 49% (95% CI, 37% to 61%), respectively (P < .001). The survival difference mostly affected patients age ≥ 40 years. Multivariate analysis identified ß(2)-microglobulin ≥ 3 mg/L (P < .001) and age ≥ 40 years (P = .029), but not ALK status, as prognostic for OS. These two variables distinguished four survival risk groups, with 8-year OS ranging from 84% to 22%. CONCLUSION Results of this long-term study enabled refinement of the prognosis of adult systemic ALCL, with ALK prognostic value dependent on age, and could provide guidance for eventual treatment adjustment.

Parenthood in survivors of Hodgkin lymphoma: an EORTC-GELA general population case-control study.

PURPOSE: We investigated the impact of Hodgkin lymphoma (HL) on parenthood, including factors influencing parenthood probability, by comparing long-term HL survivors with matched general population controls. PATIENTS AND METHODS: A Life Situation Questionnaire was sent to 3,604 survivors treated from 1964 to 2004 in successive clinical trials. Responders were matched with controls (1:3 or 4) for sex, country, education, and year of birth (10-year groups). Controls were given an artificial date of start of treatment equal to that of their matched case. The main end point was presence of biologic children after treatment, which was evaluated by using conditional logistic regression analysis. Logistic regression analysis was used to analyze factors influencing spontaneous post-treatment parenthood. RESULTS: In all, 1,654 French and Dutch survivors were matched with 6,414 controls. Median follow-up was 14 years (range, 5 to 44 years). After treatment, the odds ratio (OR) for having children was 0.77 (95% CI, 0.68 to 0.87; P < .001) for survivors compared with controls. Of 898 survivors who were childless before treatment, 46.7% achieved post-treatment parenthood compared with 49.3% of 3,196 childless controls (OR, 0.87; P = .08). Among 756 survivors with children before treatment, 12.4% became parents after HL treatment compared with 22.2% of 3,218 controls with children before treatment (OR, 0.49; P < .001). Treatment with alkylating agents, second-line therapy, and age older than 35 years at treatment appeared to reduce the chances of spontaneous post-treatment parenthood. CONCLUSION: Survivors of HL had slightly but significantly fewer children after treatment than matched general population controls. The difference concerned only survivors who had children before treatment and appears to have more personal than biologic reasons. The chance of successful post-treatment parenthood was 76%.

Premature ovarian failure and fertility in long-term survivors of Hodgkin's lymphoma: a European Organisation for Research and Treatment of Cancer Lymphoma Group and Groupe d'Etude des Lymphomes de l'Adulte Cohort Study.

PURPOSE: In this large cohort of Hodgkin's lymphoma survivors with long follow-up, we estimated the impact of treatment regimens on premature ovarian failure (POF) occurrence and motherhood, including safety of nonalkylating chemotherapy and dose-response relationships for alkylating chemotherapy and age at treatment. PATIENTS AND METHODS: The Life Situation Questionnaire was sent to 1,700 women treated in European Organisation for Research and Treatment of Cancer and Groupe d'Étude des Lymphomes de l'Adulte trials between 1964 and 2004. Women treated between ages 15 and 40 years and currently not using hormonal contraceptives (n = 460) were selected to assess occurrence of POF. Cumulative POF risk was estimated using the life-table method. Predictive factors were assessed by Cox regression analysis. RESULTS: Median follow-up was 16 years (range, 5 to 45 years). Cumulative risk of POF after alkylating chemotherapy was 60% (95% CI, 41% to 79%) and only 3% (95% CI, 1% to 7%) after nonalkylating chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine; epirubicin, bleomycin, vinblastine, and prednisone). Dose relationship between alkylating chemotherapy and POF occurrence was linear. POF risk increased by 23% per year of age at treatment. In women treated without alkylating chemotherapy at age younger than 32 years and age 32 years or older, cumulative POF risks were 3% (95% CI, 1% to 16%) and 9% (95% CI, 4% to 18%), respectively. If menstruation returned after treatment, cumulative POF risk was independent of age at treatment. Among women who ultimately developed POF, 22% had one or more children after treatment, compared with 41% of women without POF. CONCLUSION: Nonalkylating chemotherapy carries little to no excess risk of POF. Dose-response relationships for alkylating chemotherapy and age at treatment are both linear. Timely family planning is important for women at risk of POF.

Intensified chemotherapy with ACVBP plus rituximab versus standard CHOP plus rituximab for the treatment of diffuse large B-cell lymphoma (LNH03-2B): an open-label randomised phase 3 trial.

BACKGROUND: The outcome of diffuse large B-cell lymphoma has been substantially improved by the addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy regimens. We aimed to assess, in patients aged 18-59 years, the potential survival benefit provided by a dose-intensive immunochemotherapy regimen plus rituximab compared with standard treatment plus rituximab. METHODS: We did an open-label randomised trial comparing dose-intensive rituximab, doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (R-ACVBP) with subsequent consolidation versus standard rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisone (R-CHOP). Random assignment was done with a computer-assisted randomisation-allocation sequence with a block size of four. Patients were aged 18-59 years with untreated diffuse large B-cell lymphoma and an age-adjusted international prognostic index equal to 1. Our primary endpoint was event-free survival. Our analyses of efficacy and safety were of the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT00140595. FINDINGS: One patient withdrew consent before treatment and 54 did not complete treatment. After a median follow-up of 44 months, our 3-year estimate of event-free survival was 81% (95% CI 75-86) in the R-ACVBP group and 67% (59-73) in the R-CHOP group (hazard ratio [HR] 0·56, 95% CI 0·38-0·83; p=0·0035). 3-year estimates of progression-free survival (87% [95% CI, 81-91] vs 73% [66-79]; HR 0·48 [0·30-0·76]; p=0·0015) and overall survival (92% [87-95] vs 84% [77-89]; HR 0·44 [0·28-0·81]; p=0·0071) were also increased in the R-ACVBP group. 82 (42%) of 196 patients in the R-ACVBP group experienced a serious adverse event compared with 28 (15%) of 183 in the R-CHOP group. Grade 3-4 haematological toxic effects were more common in the R-ACVBP group, with a higher proportion of patients experiencing a febrile neutropenic episode (38% [75 of 196] vs 9% [16 of 183]). INTERPRETATION: Compared with standard R-CHOP, intensified immunochemotherapy with R-ACVBP significantly improves survival of patients aged 18-59 years with diffuse large B-cell lymphoma with low-intermediate risk according to the International Prognostic Index. Haematological toxic effects of the intensive regimen were raised but manageable. FUNDING: Groupe d'Etudes des Lymphomes de l'Adulte and Amgen.

(90)Y ibritumomab tiuxetan (Zevalin) combined with BEAM (Z -BEAM) conditioning regimen plus autologous stem cell transplantation in relapsed or refractory low-grade CD20-positive B-cell lymphoma. A GELA phase II prospective study.

BACKGROUND: This study was designed to evaluate the safety and efficacy of a conventional dose of yttrium-90 ((90)Y) ibritumomab tiuxetan combined with the etoposide rabinoside acytarabine melphalan (BEAM) regimen before autologous stem cell transplantation (ASCT) in chemosensitive relapsed or refractory low-grade B-cell lymphomas. PATIENTS AND METHODS: From March 2005 to August 2006, 77 prospective patients were included, 69 (90%) with follicular lymphomas. RESULTS: The last salvage chemotherapy regimen included rituximab for 74 patients and ASCT for 75 patients. Before ASCT, rates of complete response/unconfirmed response (CR/CRu) and partial response were 77% and 23%, respectively. After zevaline-BEAM (Z-BEAM), time to >1 × 10(9)/L neutrophils was 12 days (range, 9-35 days), and time to >20 × 10(9)/L platelets was 12 days (range, 3-42 days). No other significant extrahematologic toxicity was observed. Three months after ASCT, 68 patients (88%) were in CR/CRu. After a median follow-up of 28 months, 2-year event-free survival (EFS) and overall survival were 63% and 97%, respectively, but EFS for first-relapsed patients was 72%. When using patients as their own controls, 2-year EFS was superior after ASCT and compared favorably with the duration of response of last chemotherapy (62% vs. 37%, P = .007) (Point 1.10). CONCLUSION: Z-BEAM appears safe and needs to be further evaluated in a randomized trial.

Attenuated immunochemotherapy regimen (R-miniCHOP) in elderly patients older than 80 years with diffuse large B-cell lymphoma: a multicentre, single-arm, phase 2 trial.

BACKGROUND: Diffuse large B-cell lymphoma is a common cancer in elderly patients. Although treatment has been standardised in younger patients, no prospective study has been done in patients over 80 years old. We aimed to investigate the efficacy and safety of a decreased dose of CHOP (doxorubicin, cyclophosphamide, vincristine, and prednisone) chemotherapy with a conventional dose of rituximab in elderly patients with diffuse large B-cell lymphoma. METHODS: We did a prospective, multicentre, single-arm, phase 2 study of patients aged over 80 years who had diffuse large B-cell lymphoma. Patients were included from 38 centres in France and Belgium. All patients received six cycles of rituximab combined with low-dose CHOP (R-miniCHOP) at 3-week intervals. Patients received 375 mg/m(2) rituximab, 400 mg/m(2) cyclophosphamide, 25 mg/m(2) doxorubicin, and 1 mg vincristine on day 1 of each cycle, and 40 mg/m(2) prednisone on days 1-5. The primary endpoint was overall survival, both unadjusted and adjusted for treatment and baseline prognostic factors. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, NCT01087424. FINDINGS: 150 patients were enrolled between Jan 9, 2006, and Jan 23, 2009 and 149 were included in the intention-to-treat analyses. Median age was 83 years (range 80-95). After a median follow-up of 20 months (range 0-45), the median overall survival was 29 months (95% CI 21 to upper limit not reached); 2-year overall survival was 59% (49-67%). In multivariate analyses, overall survival was only affected by a serum albumin concentration of 35 g/L or less (hazard ratio 3·2, 95% CI 1·4-7·1; p=0·0053). Median progression-free survival was 21 months (95% CI 13 to upper limit not reached), with a 2-year progression free survival of 47% (38-56). 58 deaths were reported, 33 of which were secondary to lymphoma progression. 12 deaths were attributed to toxicity of the treatment. The most frequent side-effect was haematological toxicity (grade ≥3 neutropenia in 59 patients; febrile neutropenia in 11 patients). INTERPRETATION: R-miniCHOP offers a good compromise between efficacy and safety in patients aged over 80 years old. R-miniCHOP should be considered as the new standard treatment in this subgroup of patients. FUNDING: Groupe d'Etude des Lymphomes de l'Adulte (GELA).

SUVmax reduction improves early prognosis value of interim positron emission tomography scans in diffuse large B-cell lymphoma.

The prognostic value of interim positron emission tomography (PET) interpreted according to visual criteria is a matter of debate in diffuse large B-cell lymphoma (DLBCL). Maximal standardized uptake value reduction (ΔSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analyzed PET done at baseline (PET0) and after 2 (PET2) and 4 (PET4) cycles in 85 patients with high-risk DLBCL enrolled on a prospective multicenter trial. All images were centrally reviewed and interpreted visually according to the International Harmonization Project criteria and by computing ΔSUVmax between PET0 and PET2 (ΔSUVmaxPET0-2) or PET4 (ΔSUVmaxPET0-4). Optimal cutoff to predict progression or death was 66% for ΔSUVmaxPET0-2 and 70% for ΔSUVmaxPET0-4. Outcomes did not differ significantly whether PET2 and PET4 were visually positive or negative. Inversely, ΔSUVmaxPET0-2 analysis (> 66% vs ≤ 66%) identified patients with significantly different 2-year progression-free survival (77% vs 57%; P = .0282) and overall survival (93% vs 60%; P < .0001). ΔSUVmaxPET0-4 analysis (> 70% vs ≤ 70%) seemed even more predictive for 2-year progression-free survival (83 vs 40%; P < .0001) and overall survival (94% vs 50%; P < .0001). ΔSUVmax analysis of sequential interim PET is feasible for high-risk DLBCL and better predicts outcome than visual analysis. The trial was registered at http://clinicaltrials.gov as NCT00498043.

Changes in antithrombin and fibrinogen levels during induction chemotherapy with L-asparaginase in adult patients with acute lymphoblastic leukemia or lymphoblastic lymphoma. Use of supportive coagulation therapy and clinical outcome: the CAPELAL study.

BACKGROUND: The effects of L-asparaginase on hemostasis during induction chemotherapy are less defined in adults than in children. We, therefore, studied the effects of L-asparaginase in adult patients. DESIGN AND METHODS: This was a retrospective analysis of 214 patients treated with L-asparaginase (7500 IU/m(2) x 6) for acute lymphoblastic leukemia or lymphoblastic lymphoma. Between day 1 of the induction course and discharge, clinical events, and biological and therapeutic modifications were reviewed. RESULTS: Antithrombin and fibrinogen levels were lower than 60% and 1 g/L in 71% and 73% of patients, respectively. Twenty thromboses occurred in 9.3% of the patients; these patients had a median antithrombin level of 53% (range, 21-111) at the time of the event. Forty-two episodes of bleeding occurred in 31 patients with a median fibrinogen level of 1.3 g/L. Infusions of L-asparaginase were reduced or delayed in 64% of patients due to low fibrinogen and/or antithrombin levels. Fresh-frozen plasma, antithrombin and fibrinogen were infused in 31%, 41% and 52% of patients, respectively. The mean antithrombin and fibrinogen levels increased from 61% to 88% and from 1 to 1.4 g/L after infusion of antithrombin or fibrinogen respectively, while both levels remained unchanged after the infusion of fresh-frozen plasma. In patients who received antithrombin concentrates L-asparaginase injections were less frequently omitted or delayed (53% vs. 72%, p=0.005), the rate of thrombosis was lower (4.8% vs. 12.2%, p=0.04) and the disease-free survival was also reduced (p=0.05). CONCLUSIONS: This retrospective study suggests that antithrombin concentrates may have a beneficial effect on the outcome of adults treated for acute lymphoblastic leukemia with L-asparaginase; prospective studies are essential to confirm this hypothesis.

Outcome of adult T-lymphoblastic lymphoma after acute lymphoblastic leukemia-type treatment: a GOELAMS trial.

BACKGROUND AND OBJECTIVES: T-lymphoblastic lymphoma is an infrequent disease usually treated as T-acute lymphoblastic leukemia with an induction chemotherapy course and sequential reinduction and maintenance chemotherapy. The T-LBL/ALL-GOELAL02 study evaluated the impact of randomized reinduction chemotherapy against intensified conditioning followed by autologous stem cell transplantation (ASCT), after an induction regimen of the type used for acute lymphoblastic leukemia (ALL). DESIGN AND METHODS: Patients with favorable characteristics were randomized to receive chemotherapy or ASCT. Patients with unfavorable characteristics (bone marrow involvement and age over 35 years old or leukocytosis >30 x 10(9)/L or failure to achieve medullar complete remission [CR] after one induction course) received a second induction course and ASCT. RESULTS: Among 45 patients, the CR rate was 71% after induction and 87% after a second induction course. Within the group of 27 patients with favorable characteristics, ten received ASCT and 17 chemotherapy. Ten patients in the group with unfavorable characteristics received ASCT. The 7-year overall survival and progression-free survival rates were 64 and 65%, respectively. Surprisingly, CR obtained after only two induction courses was associated with improved overall survival (p=0.04). None of the known prognostic factors significantly affected survival. INTERPRETATION AND CONCLUSIONS: Randomized maintenance or high-dose therapy (HDT) and ASCT or intensified HDT according to initial presentation gave similar overall and relapse-free survival rates. However, HDT allowed sparing of mediastinal irradiation and shortened treatment duration.
