Anaemia in hospitalized cancer patients: a retrospective study of two cohorts before and after the guideline update.

Introduction The incidence of anaemia and its consequences are often underestimated during cancer management. We propose to evaluate the situation before and after the recommendations were updated in order to assess their impact on the day-to-day practice. Methods In this single-center retrospective study, eligible patients were treated for cancer and warranted overnight hospitalization over two periods (n=206 in 2011, n=143 in 2018). The diagnosis of anaemia was defined by a hemoglobin level below 12 and 13 g/dl for women and men, respectively. Results The prevalence of anaemia was 26% in 2011 and 16% in 2018 (p<.001). Biological assessment had changed between the two periods, with more tests of iron metabolism and measurements of inflammatory parameters. Patients hospitalized in 2018 had more advanced cancer and more severe anaemia (8.2 g/dl [±1.07] in 2011 vs 7.9 g/dl [±1.18] in 2018). Rate of transfusion therapy did not change, but patients with mild and moderate anaemia were transfused less in 2018 (57% in 2011 vs 44% in 2018). Intravenous iron and erythropoiesis-stimulating agent were used more frequently in 2018 (1% and 5%, and 13% and 23% in 2011 and 2018, respectively), mainly for mild anaemia and life-threatening anaemia, respectively. Overall survival was poor in both cohorts at 24 months (15.4% in 2011 and 6.5% in 2018, p=.048). Conclusion Practices have changed in the diagnosis of anaemia and prescriptions for erythropoiesis-stimulating agents and intravenous iron have increased. Efforts must continue to explore the causes of anaemia, optimize patients' quality of life of and reduce transfusions.

Final results on effectiveness and safety of Ibrutinib in patients with chronic lymphocytic leukemia from the non-interventional FIRE study.

We conducted an observational study (FIRE) to understand the effectiveness and safety outcomes of ibrutinib in patients with chronic lymphocytic leukemia (CLL) in France, after a maximum follow-up of five years. Patients were included according to the French marketing authorization in 2016 (i.e. patients with relapsed or refractory CLL or to previously untreated CLL patients with deletion 17p and/or tumor protein p53 mutations unsuitable for chemoimmunotherapy) and could have initiated ibrutinib more than 30 days prior their enrolment in the study (i.e. retrospective patients) or between 30 days before and 14 days after their enrolment (i.e. prospective patients). The results showed that in the effectiveness population (N = 388), the median progression-free survival (PFS) was 53.1 (95% CI: 44.5-60.5) months for retrospective patients and 52.9 (95% CI: 40.3-60.6) months for prospective patients and no difference was shown between the PFS of patients who had at least one dose reduction versus the PFS of patients without dose reduction (p = 0.7971 for retrospective and p = 0.3163 for prospective patients). For both retrospective and prospective patients, the median overall survival was not reached. The most frequent treatment-emergent adverse event of interest was infections (57.6% retrospective; 71.4% prospective). A total of 14.6% of the retrospective patients and 22.4% of the prospective patients had an adverse event leading to death. Our findings on effectiveness were consistent with other studies and the fact that patients with dose reductions had similar PFS than patients without dose reduction is reassuring. No additional safety concerns than those already mentioned in previous studies could be noticed.Trial registration ClinicalTrials.gov, NCT03425591.

A New Option for Pain Prevention Using a Therapeutic Virtual Reality Solution for Bone Marrow Biopsy (REVEH Trial): Open-Label, Randomized, Multicenter, Phase 3 Study.

BACKGROUND: Evidence regarding the analgesic effect of distraction through immersion in virtual reality (VR) for care-induced pain has been documented in several phase 2 trials, but comparison with standard treatments in large, randomized studies is needed. OBJECTIVE: In this open-label, multicenter, randomized, phase 3 trial, we evaluated the safety and efficacy of a novel VR therapy solution for distraction in the context of bone marrow biopsy. METHODS: Bliss is a VR software with 4 imaginary interactive environments in 3 dimensions with binaural sound (head-mounted display). Efficacy regarding pain intensity was evaluated using a visual analog scale (VAS; score from 0 to 10) immediately after the biopsy. Secondary end points were anxiety and tolerance. Modified intention-to-treat analysis was performed. RESULTS: Overall, 126 patients with previously documented untreated or suspected malignant hemopathy between September 6, 2018, and May 18, 2020, were randomly assigned in a 1:1 ratio to receive pain prevention with a mixture of nitrous oxide/oxygen (MEOPA; n=63) or VR (n=63) before and during the bone marrow biopsy. We excluded 8 patients from the final analysis (3 in the MEOPA group and 5 in the VR group). All patients received local anesthesia (lidocaine) before biopsy. Follow-up was limited to 1 month after the biopsy. Participants' median age was 65.5 (range 18-87) years, and 54.2% (64/118) of patients were male. The average pain intensity was 3.5 (SD 2.6, 95% CI -1.6 to 8.6) for the MEOPA group and 3.0 (SD 2.4, 95% CI -1.7 to 7.7) for the VR group, without any significant differences in age, sex, center, and hemopathy (P=.26). Concerning anxiety, 67.5% (79/117; fear of pain questionnaire) of the patients were afraid before the biopsy, and anxiety scores were moderate to very high in 26.3% (30/114; revised Spielberger State-Trait Anxiety Inventory questionnaire) of the patients before the biopsy and 9.0% (10/114) after the biopsy for all patients, without a significant difference between the 2 groups (P=.83). Immersion in VR was well tolerated by the majority (54/57, 95%) of patients in the VR group. CONCLUSIONS: The intensity of pain did not significantly differ between both arms. VR was well tolerated, and the satisfaction of patients, nurses, and physicians was very high. VR could be an alternative treatment in case of contraindication or intolerance to MEOPA.

Physical Activity Program for the Survival of Elderly Patients With Lymphoma: Study Protocol for Randomized Phase 3 Trial.

BACKGROUND: The practice of regular physical activity can reduce the incidence of certain cancers (colon, breast, and prostate) and improve overall survival after treatment by reducing fatigue and the risk of relapse. This impact on survival has only been demonstrated in active patients with lymphoma before and after treatment. As poor general health status reduces the chances of survival and these patients are most likely to also have sarcopenia, it is important to be able to improve their physical function through adapted physical activity (APA) as part of supportive care management. Unfortunately, APA is often saved for patients with advanced blood cancer. As a result, there is a lack of data regarding the impact of standardized regular practice of APA and concomitant chemotherapy as first-line treatment on lymphoma survival. OBJECTIVE: This study aimed to assess the impact of a new and open rehabilitation program suitable for a frail population of patients treated for diffuse large B-cell lymphoma (DLBCL). METHODS: PHARAOM (Physical Activity Program for the Survival of Elderly Patients with Lymphoma) is a phase 3 randomized (1:1) study focusing on a frail population of patients treated for DLBCL. The study will include 186 older adult patients with DLBCL (aged >65 years) receiving rituximab and chemotherapy. Overall, 50% (93/186) of patients (investigational group) will receive APA along with chemotherapy, and they will be supervised by a dedicated qualified kinesiologist. The APA program will include endurance and resistance training at moderate intensity 3 times a week during the 6 months of chemotherapy. The primary end point of this study will be event-free survival of the patients. The secondary end points will include the overall survival, progression-free survival, prevalence of sarcopenia and undernutrition, and patients' quality of life. This study will be conducted in accordance with the principles of the Declaration of Helsinki. RESULTS: Recruitment, enrollment, and data collection began in February 2021, and 4 participants have been enrolled in the study as of July 2022. Data analysis will begin after the completion of data collection. Future outcomes will be published in peer-reviewed health-related research journals and presented at national congress, and state professional meetings. This publication is based on protocol version 1.1, August 3, 2020. CONCLUSIONS: The PHARAOM study focuses on highlighting the benefits of APA intervention on survival during the period of first-line treatment of patients with DLBCL. This study could also contribute to our understanding of how an APA program can reduce complications such as sarcopenia in patients with lymphoma and improve their quality of life. By documenting the prevalence and relationship between sarcopenia and exercise load, we might be able to help physicians plan better interventions in the care of patients with DLBCL.

Real-world study of children and young adults with myeloproliferative neoplasms: identifying risks and unmet needs.

Myeloproliferative neoplasms (MPNs) are uncommon in children/young adults. Here, we present data on unselected patients diagnosed before 25 years of age included from 38 centers in 15 countries. Sequential patients were included. We identified 444 patients, with median follow-up 9.7 years (0-47.8). Forty-nine (11.1%) had a history of thrombosis at diagnosis, 49 new thrombotic events were recorded (1.16% patient per year [pt/y]), perihepatic vein thromboses were most frequent (47.6% venous events), and logistic regression identified JAK2V617F mutation (P = .016) and hyperviscosity symptoms (visual disturbances, dizziness, vertigo, headache) as risk factors (P = .040). New hemorrhagic events occurred in 44 patients (9.9%, 1.04% pt/y). Disease transformation occurred in 48 patients (10.9%, 1.13% pt/y), usually to myelofibrosis (7.5%) with splenomegaly as a novel risk factor for transformation in essential thrombocythemia (ET) (P= .000) in logistical regression. Eight deaths (1.8%) were recorded, 3 after allogeneic stem cell transplantation. Concerning conventional risk scores: International Prognostic Score for Essential Thrombocythemia-Thrombosis and new International Prognostic Score for Essential Thrombocythemia-Thrombosis differentiated ET patients in terms of thrombotic risk. Both scores identified high-risk patients with the same median thrombosis-free survival of 28.5 years. No contemporary scores were able to predict survival for young ET or polycythemia vera patients. Our data represents the largest real-world study of MPN patients age < 25 years at diagnosis. Rates of thrombotic events and transformation were higher than expected compared with the previous literature. Our study provides new and reliable information as a basis for prospective studies, trials, and development of harmonized international guidelines for the specific management of young patients with MPN.

Extranodal classical Hodgkin lymphoma involving the spinal cord: case report and review of the literature.

Primary CNS involvement is very rare in Hodgkin lymphoma. Here we present two cases of spinal cord dissemination. Two women of 40 and 65 years of age presented symptoms of spinal cord injury; imaging showed an intramedullary mass in T10 and T2, respectively, without vertebral involvement and upper diaphragmatic lymph nodes. Lymph-node biopsy confirmed the diagnosis of classical Hodgkin lymphoma in both patients. The first patient received four cycles of chemotherapy (escalated BEACOPP and ABVD) with intrathecal therapy, and the second four cycles of doxorubicin, vinblastine, dacarbazine (AVD) and local irradiation after surgery decompression. Complete metabolic response was obtained at the end of treatment. After 5 and 7 years of follow-up respectively, neurological deficits persisted in both.

Lymph-node infiltration is the most common presentation in Hodgkin lymphoma at diagnosis. Primary extranodal involvement is rare and spinal cord infiltration exceptional. Back pain, tingling and vesico-sphincter dysfunctions are the main symptoms. 18F-fluorodeoxyglucose (FDG) PET and MRI can detect the location and extension of neurological involvement. We present here two cases of tumoral myelitis and a review of the literature. Local treatment (surgery/radiotherapy) is often administered together with chemotherapy to optimize local control and to avoid long-term sequelae.

Outcomes after first-line immunochemotherapy for primary mediastinal B-cell lymphoma: a LYSA study.

Primary mediastinal B-cell lymphoma (PMBL) is a rare type of aggressive lymphoma typically affecting young female patients. The first-line standard of care remains debated. We performed a large multicenter retrospective study in 25 centers in France and Belgium to describe PMBL patient outcomes after first-line treatment in real-life settings. A total of 313 patients were enrolled and received rituximab (R) plus ACVBP (doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone) (n = 180) or CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) delivered every 14 days (R-CHOP14, n = 76) or 21 days (R-CHOP21, n = 57) and consolidation strategies in modalities that varied according to time and institution, mainly guided by positron emission tomography. Consolidation autologous stem cell transplantation was performed for 46 (25.6%), 24 (31.6%), and 1 (1.8%) patient in the R-ACVBP, R-CHOP14, and R-CHOP21 groups, respectively (P < .001); only 17 (5.4%) patients received mediastinal radiotherapy. The end-of-treatment complete metabolic response rates were 86.3%, 86.8%, and 76.6% (P = .23) in the R-ACVBP, R-CHOP14, and R-CHOP21 groups. The median follow-up was 44 months, and the R-ACVBP, R-CHOP14, and R-CHOP21 three-year progression-free survival probabilities were 89.4% (95% confidence interval [CI], 84.8-94.2), 89.4% (95% CI, 82.7-96.6), and 74.7% (95% CI, 64-87.1) (P = .018). A baseline total metabolic tumor volume (TMTV) ≥360 cm3 was associated with a lower progression-free survival (hazard ratio, 2.18; 95% CI, 1.05-4.53). Excess febrile neutropenia (24.4% vs 5.3% vs 5.3%; P < .001) and mucositis (22.8% vs 3.9% vs 1.8%; P < .001) were observed with R-ACVBP compared with the R-CHOP regimens. Patients with PMBL treated with dose-dense immunochemotherapy without radiotherapy have excellent outcomes. R-ACVBP acute toxicity was higher than that of R-CHOP14. Our data confirmed the prognostic importance of baseline TMTV.

Venetoclax plus obinutuzumab versus chlorambucil plus obinutuzumab for previously untreated chronic lymphocytic leukaemia (CLL14): follow-up results from a multicentre, open-label, randomised, phase 3 trial.

BACKGROUND: Venetoclax plus obinutuzumab has been established as a fixed-duration treatment regimen for patients with chronic lymphocytic leukaemia. We compared the long-term efficacy after treatment cessation of the combination of venetoclax plus obinutuzumab with chlorambucil plus obinutuzumab in patients with previously untreated chronic lymphocytic leukaemia. METHODS: CLL14 is a multicentre, randomised, open-label, phase 3 trial done at 196 sites in 21 countries. Eligible patients were aged 18 years or older, had untreated chronic lymphocytic leukaemia, and coexisting conditions with a cumulative illness rating scale greater than 6, a creatinine clearance of 30-69 mL/min, or both. Patients were randomly assigned (1:1) via a web and voicemail system with allocation concealment and based on a computer-generated randomisation schedule with a block size of six and stratified by Binet stage and geographical region. Patients received either venetoclax plus obinutuzumab (oral venetoclax initiated on day 22 of cycle 1 [28-day cycles], with a 5-week dose ramp-up [20 mg, 50 mg, 100 mg, and 200 mg, then 400 mg daily for 1 week], thereafter continuing at 400 mg daily until completion of cycle 12; combined with intravenous obinutuzumab for six cycles starting with 100 mg on day 1 and 900 mg on day 2 [or 1000 mg on day 1], 1000 mg on days 8 and day 15 of cycle 1, and subsequently 1000 mg on day 1 of cycles 2 through 6) or chlorambucil plus obinutuzumab (oral chlorambucil at 0·5 mg/kg bodyweight on days 1 and 15 of each cycle for 12 cycles combined with the same obinutuzumab regimen). The primary endpoint was investigator-assessed progression-free survival in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. Patient enrolment is complete, and the study is registered with ClinicalTrails.gov, NCT02242942. FINDINGS: Between Aug 7, 2015, and Aug 4, 2016, 432 patients were enrolled and randomly assigned to receive either venetoclax plus obinutuzumab (n=216) or chlorambucil plus obinutuzumab (n=216). All patients had been off treatment for at least 24 months at data collection. At a median follow-up of 39·6 months (IQR 36·8-43·0), patients given venetoclax plus obinutuzumab had a significantly longer progression-free survival than did patients given chlorambucil plus obinutuzumab (HR 0·31, 95% CI 0·22-0·44; p<0·0001). Median progression-free survival was not reached (95% CI not estimable to not estimable) in the venetoclax plus obinutuzumab group vs 35·6 months (33·7-40·7) in the chlorambucil plus obinutuzumab group. The most common grade 3 or 4 adverse event in both groups was neutropenia (112 [53%] of 212 patients in the venetoclax plus obinutuzumab group versus 102 [48%] of 214 patients in the chlorambucil plus obinutuzumab group). Serious adverse events occurred in 115 (54%) of 212 patients in the venetoclax plus obinutuzumab group and 95 (44%) of 214 patients in the chlorambucil plus obinutuzumab group. Venetoclax or chlorambucil treatment-related deaths were reported in one (1%) of 212 patients in the venetoclax plus obinutuzumab group (n=1 sepsis) and two (1%) of 214 patients in the chlorambucil plus obinutuzumab group (n=1 septic shock, n=1 metastatic skin squamous carcinoma). INTERPRETATION: 2 years after treatment cessation, venetoclax plus obinutuzumab continues to significantly improve progression-survival compared with chlorambucil plus obinutuzumab, thereby providing a limited duration treatment option for patients with previously untreated chronic lymphocytic leukaemia.

Venetoclax-rituximab with or without bendamustine vs bendamustine-rituximab in relapsed/refractory follicular lymphoma.

This open-label phase 2 study (CONTRALTO) assessed the safety and efficacy of BCL-2 inhibitor venetoclax (VEN) plus rituximab (R), and VEN plus bendamustine (B) and R, vs B + R (BR) alone in relapsed/refractory (R/R) follicular lymphoma. Patients in the chemotherapy-free arm (arm A: VEN + R) received VEN 800 mg/d plus R 375 mg/m2 on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 4, 6, 8, 10, and 12. After a safety run-in with VEN 600 mg, patients in the chemotherapy-containing cohort were randomized to either VEN + BR (arm B; VEN 800 mg/d for 1 year + 6 cycles of BR [B 90 mg/m2 on days 1 and 2 and R 375 mg/m2 on day 1]) or 6 cycles of BR (arm C). Overall, 163 patients were analyzed (9 in the safety run-in and 52, 51, and 51 in arms A, B, and C, respectively). Complete metabolic/complete response rates were 17% (arm A), 75% (arm B), and 69% (arm C). Of patients in arm B, only 61% received ≥90% of the planned B dose vs 96% of patients in arm C. More frequent hematologic toxicity resulted in more reduced dosing/treatment discontinuation in arm B vs arm C. Rates of grade 3/4 adverse events were 51.9%, 93.9%, and 60.0% in arms A, B, and C, respectively. VEN + BR led to increased toxicity and lower dose intensity of BR than in arm C, but efficacy was similar. Optimizing dose and schedule to maintain BR dose intensity may improve efficacy and tolerability of VEN + BR, while VEN + R data warrant further study. This study was registered at www.clinicaltrials.gov as #NCT02187861.

Lenalidomide maintenance for diffuse large B-cell lymphoma patients responding to R-CHOP: quality of life, dosing, and safety results from the randomised controlled REMARC study.

Lenalidomide maintenance therapy prolonged progression-free survival (PFS) versus placebo in elderly patients with diffuse large B-cell lymphoma (DLBCL) responding to induction chemotherapy in the phase 3 REMARC study. This subpopulation analysis assessed the impact of lenalidomide maintenance and treatment-emergent adverse events (TEAEs) on health-related quality of life (HRQOL). Global health status (GHS), and physical functioning and fatigue subscales were evaluated in patients who completed the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire-C30 v3.0. The impact of TEAEs classified post hoc as subjective (patients can feel) or observable (only measurable by physicians) on dose reductions and discontinuations was assessed. Among 457 patients (lenalidomide, n = 229; placebo, n = 228), mean (standard deviation) GHS was similar between treatment arms [68·2 (20·7) Versus 72·0 (17·8)] at randomisation and remained similar during maintenance. Patients receiving lenalidomide experienced no meaningful changes in GHS, physical functioning, or fatigue. Observable TEAEs were more common (81·1% Versus 66·3%) and more likely to lead to dose reductions, than subjective TEAEs in both arms. PFS was superior in the lenalidomide arm regardless of dose reduction. Lenalidomide maintenance prolonged PFS and did not negatively impact HRQOL in patients with DLBCL despite TEAEs being more common, when compared with placebo.

Venetoclax and Obinutuzumab in Patients with CLL and Coexisting Conditions.

BACKGROUND: The BCL2 inhibitor venetoclax has shown activity in patients with chronic lymphocytic leukemia (CLL), but its efficacy in combination with other agents in patients with CLL and coexisting conditions is not known. METHODS: In this open-label, phase 3 trial, we investigated fixed-duration treatment with venetoclax and obinutuzumab in patients with previously untreated CLL and coexisting conditions. Patients with a score of greater than 6 on the Cumulative Illness Rating Scale (scores range from 0 to 56, with higher scores indicating more impaired function of organ systems) or a calculated creatinine clearance of less than 70 ml per minute were randomly assigned to receive venetoclax-obinutuzumab or chlorambucil-obinutuzumab. The primary end point was investigator-assessed progression-free survival. The safety of each regimen was also evaluated. RESULTS: In total, 432 patients (median age, 72 years; median Cumulative Illness Rating Scale score, 8; median creatinine clearance, 66.4 ml per minute) underwent randomization, with 216 assigned to each group. After a median follow-up of 28.1 months, 30 primary end-point events (disease progression or death) had occurred in the venetoclax-obinutuzumab group and 77 had occurred in the chlorambucil-obinutuzumab group (hazard ratio, 0.35; 95% confidence interval [CI], 0.23 to 0.53; P<0.001). The Kaplan-Meier estimate of the percentage of patients with progression-free survival at 24 months was significantly higher in the venetoclax-obinutuzumab group than in the chlorambucil-obinutuzumab group: 88.2% (95% CI, 83.7 to 92.6) as compared with 64.1% (95% CI, 57.4 to 70.8). This benefit was also observed in patients with TP53 deletion, mutation, or both and in patients with unmutated immunoglobulin heavy-chain genes. Grade 3 or 4 neutropenia occurred in 52.8% of patients in the venetoclax-obinutuzumab group and in 48.1% of patients in the chlorambucil-obinutuzumab group, and grade 3 or 4 infections occurred in 17.5% and 15.0%, respectively. All-cause mortality was 9.3% in the venetoclax-obinutuzumab group and 7.9% in the chlorambucil-obinutuzumab group. These differences were not significant. CONCLUSIONS: Among patients with untreated CLL and coexisting conditions, venetoclax-obinutuzumab was associated with longer progression-free survival than chlorambucil-obinutuzumab. (Funded by F. Hoffmann-La Roche and AbbVie; ClinicalTrials.gov number, NCT02242942.).

Prospective study of a web-mediated management of febrile neutropenia related to chemotherapy (Bioconnect).

BACKGROUND: We aimed to investigate whether patient self-evaluated symptoms transmitted via Internet is feasible between planned visits to provide an early management of fever and neutropenia induced by chemotherapy, and if it can reduce hospitalizations for severe neutropenia. METHODS: Patients who received a chemotherapy regimen with an overall risk of febrile neutropenia ≥ 20% had to report daily temperature between physician planned visits using a web application. Fever and clinical signs of seriousness were reported to the physician (if some criteria were fulfilled in a specific algorithm) via automatic email notifications by the web application. Patients could be hospitalized quickly or could take over at home, make blood count, and take predefined oral antibiotics if indicated. Primary outcome was patient's compliance and satisfaction. The number and the cost of hospitalization were also assessed and compared with an historical cohort of patients with similar clinical conditions and treatment. RESULTS: Among the 41 patients included, 36 (87.8%) used the web application with 88% of daily compliance and 90% (28/33) of satisfaction. One patient (2.7%) had planned hospitalization after the web application alert. In the historical cohort, the rate of unplanned hospitalization for febrile neutropenia was 17% (6 patients) and 2.7% (1 patient) in users of the web application cohort. The cumulative cost of hospitalization for neutropenia was USD 28,827 in the historical cohort and USD 6563 in the web application cohort. CONCLUSION: Web-mediated follow-up of febrile neutropenia is feasible. It led to high patient satisfaction, high compliance, and a possible reduction of the number and the cost of hospitalizations.

Tandem haematopoietic stem cell transplantation for High Risk relapsed/refractory Hodgkin Lymphoma: a LYSA study.

Tandem stem cell transplantation (SCT) is an option for high-risk relapsed/refractory Hodgkin Lymphoma (HL) patients. We evaluated the tolerance/efficacy of double autologous or autologous SCT (ASCT) followed by allogenic SCT (alloSCT) in 120 HL patients prospectively registered on a French nationwide database. Median age was 26 (14-56) years. Complete remission rate was 60%, including 33% after a single line, and another 27% after two or more salvage regimens. Partial response rate was 32%, and 8% suffered treatment failure. Overall, 115 (96%) patients underwent a first ASCT, and 73 (61%) had a tandem SCT, including alloSCT in 44 (60%) and ASCT in 29 (40%). The median follow-up was 43 months (4.8-73.7 months). The two-year progression-free survival rate for the whole population and for patients receiving tandem transplant was 56% (95% confidence interval [CI]: 46-65%) and 71% (95% CI: 49-84%), respectively. Among tandem transplants, we observed 20 deaths (17%), 10 of which were transplant-related (6 alloSCT and 4 ASCT). We suggest that tandem SCT is efficient in high-risk relapsed/refractory HL patients, although transplant-related mortality remains high. The benefit of tandem SCT should be balanced with the efficacy of Brentuximab vedotin-based post-transplant consolidative strategies in high-risk relapsed/refractory HL patients.

Totally implantable venous access ports: a prospective long-term study of early and late complications in adult patients with cancer.

PURPOSE: Totally implantable venous access ports (TIVAP) have been widely used for many years in the management of patients suffering from cancer. The implantation and long-term use of TIVAPs are associated with mechanical, thrombotic, and infectious complications. This is the first exhaustive prospective study of all complications occurring in a whole population on long-term follow-up and therefore allows an objective assessment to be made of the safety of TIVAPs. METHODS: We carried out a prospective single-center observational study. All adult patients with cancer who had a TIVAP implanted between January 1 and December 31, 2006 were registered. Early and late complications were recorded until the removal of the device, the patient's death, or until December 31, 2013. Exhaustive data concerning patients and TIVAP was recorded at time of implantation. RESULTS: Four hundred and ninety-three TIVAPs were implanted in 483 adult cancer patients and were followed during a period from 1 to 94 months (median = 18 months) representing a global quantity of 367,359 catheter-days. Eighty-seven complications were recorded (0.237/1000 catheter-days), including 37 infections (0.101/1000 catheter-days), 17 thrombotic events (0.046/1000 catheter-days), and 9 extravasations. Out of the 87 events, 62 (71.3%) occurred during the first year after implantation. Events were therefore extremely rare after 1 year. Thromboembolic and infectious complications were rare and no risk factors for these were found. CONCLUSIONS: This study demonstrates excellent tolerability, with only occasional complications. Most of these occurred during the year following implantation. A TIVAP may also be left in place for an extremely long time.

R-CHOP 14 with or without radiotherapy in nonbulky limited-stage diffuse large B-cell lymphoma.

The benefit of radiotherapy (RT) after chemotherapy in limited-stage diffuse large B-cell lymphoma (DLBCL) remains controversial. We conducted a randomized trial in patients with nonbulky limited-stage DLBCL to evaluate the benefit of RT after rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Patients were stratified according to the modified International Prognostic Index, including lactate dehydrogenase, Eastern Cooperative Oncology Group performance status, age, and disease stage. The patients received 4 or 6 consecutive cycles of R-CHOP delivered once every 2 weeks, followed or not by RT at 40 Gy delivered 4 weeks after the last R-CHOP cycle. All patients were evaluated by fluorodeoxyglucose-positron emission tomography scans performed at baseline, after 4 cycles of R-CHOP, and at the end of treatment. The primary objective of the trial was event-free survival (EFS) from randomization. The trial randomly assigned 165 patients in the R-CHOP arm and 169 in the R-CHOP plus RT arm. In an intent-to-treat analysis with a median follow-up of 64 months, 5-year EFS was not statistically significantly different between the 2 arms, with 89% ± 2.9% in the R-CHOP arm vs 92% ± 2.4% in the R-CHOP plus RT arm (hazard ratio, 0.61; 95% confidence interval [CI], 0.3-1.2; P = .18). Overall survival was also not different at 92% (95% CI, 89.5%-94.5%) for patients assigned to R-CHOP alone and 96% (95% CI, 94.3%-97.7%) for those assigned to R-CHOP plus RT (P = not significant). R-CHOP alone is not inferior to R-CHOP followed by RT in patients with nonbulky limited-stage DLBCL. This trial was registered at www.clinicaltrials.gov as #NCT00841945.

Rituximab after Autologous Stem-Cell Transplantation in Mantle-Cell Lymphoma.

BACKGROUND: Mantle-cell lymphoma is generally incurable. Despite high rates of complete response after initial immunochemotherapy followed by autologous stem-cell transplantation, patients have relapses. We investigated whether rituximab maintenance therapy at a dose of 375 mg per square meter of body-surface area administered every 2 months for 3 years after transplantation would prolong the duration of response. METHODS: In a phase 3 trial involving 299 patients who were younger than 66 years of age at diagnosis, we randomly assigned 240 patients to receive rituximab maintenance therapy or to undergo observation after autologous stem-cell transplantation (120 patients per group); 59 patients did not undergo randomization. The primary end point was event-free survival (with an event defined as disease progression, relapse, death, allergy to rituximab, or severe infection) after transplantation among patients who underwent randomization. RESULTS: After four courses of immunochemotherapy induction (rituximab, dexamethasone, cytarabine, and a platinum derivative [R-DHAP]), the overall response rate was 89%, and the complete response rate 77%. Transplantation was performed in 257 patients. The median follow-up from randomization after transplantation was 50.2 months (range, 46.4 to 54.2). Starting from randomization, the rate of event-free survival at 4 years was 79% (95% confidence interval [CI], 70 to 86) in the rituximab group versus 61% (95% CI, 51 to 70) in the observation group (P=0.001). The rate of progression-free survival at 4 years was 83% (95% CI, 73 to 88) in the rituximab group versus 64% (95% CI, 55 to 73) in the observation group (P<0.001). The rate of overall survival was 89% (95% CI, 81 to 94) in the rituximab group versus 80% (95% CI, 72 to 88) in the observation group (P=0.04). According to a Cox regression unadjusted analysis, the rate of overall survival at 4 years was higher in the rituximab group than in the observation group (hazard ratio for death, 0.50; 95% CI, 0.26 to 0.99; P=0.04). CONCLUSIONS: Rituximab maintenance therapy after transplantation prolonged event-free survival, progression-free survival, and overall survival among patients with mantle-cell lymphoma who were younger than 66 years of age at diagnosis.

Transformed Waldenström macroglobulinaemia: clinical presentation and outcome. A multi-institutional retrospective study of 77 cases from the French Innovative Leukemia Organization (FILO).

Histological transformation (HT) to diffuse large B-cell lymphoma (DLBCL) is a rare and poorly reported complication of Waldenström macroglobulinaemia (WM). We performed a retrospective study of 77 WM patients with biopsy-proven transformation to DLBCL. The median time from WM diagnosis to HT was 4·6 years and 16 patients (21%) had never been treated for WM. At HT, extranodal sites were observed in 91% of patients with a rather high incidence of central nervous system, cutaneous or testicular involvement. Fluorodeoxyglucose-positron emission tomography was performed in half of the patients and the median maximum standardized uptake value was 15 for transformed disease. More than 80% of cases with available data for assessment by the Hans' algorithm harboured a non-germinal centre B-cell phenotype. First-line treatment for transformation consisted of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone)-like regimen in 85% of patients. The overall response rate after first-line treatment was 61% and the median overall survival was only 16 months for the entire cohort. Time to transformation above 5 years (P = 0·0004) and elevated LDH (P = 0·02) were associated with worse outcome. Based on these findings, HT should be considered and lead to a biopsy in WM patients presenting with extranodal involvement, elevated LDH and constitutional symptoms. The optimal therapeutic approaches remain to be defined.
