RESUMO

BACKGROUND: Vincristine plus dexamethasone pulses are generally used throughout maintenance treatment for childhood acute lymphoblastic leukaemia. However, previous studies remain inconclusive about the benefit of this maintenance therapy and the absence of randomised, controlled trials in patients with low-risk or high-risk acute lymphoblastic leukaemia provides uncertainty. We therefore aimed to determine if this therapy could be safely omitted beyond 1 year of treatment without leading to an inferior outcome in any risk subgroup of childhood acute lymphoblastic leukaemia. METHODS: This open-label, multicentre, randomised, phase 3, non-inferiority trial involved 20 major medical centres across China. We enrolled patients who were aged 0-18 years with newly diagnosed acute lymphoblastic leukaemia that was subsequently in continuous remission for 1 year after initial treatment. Patients with secondary malignancy or primary immunodeficiency were excluded. Eligible patients were classified as having low-risk, intermediate-risk, or high-risk acute lymphoblastic leukaemia based on minimal residual disease and immunophenotypic and genetic features of leukaemic cells. Randomisation and analyses were done separately for the low-risk and intermediate-to-high-risk cohorts. Randomisation was generated by the study biostatistician with a block size of six. Stratification factors included participating centre, sex, and age at diagnosis; the low-risk cohort was additionally stratified for ETV6-RUNX1 status, and the intermediate-to-high-risk cohort for cell lineage. Patients in each risk cohort were randomly assigned (1:1) to either receive (ie, the control group) or not receive (ie, the experimental group) seven pulses of intravenous vincristine (1·5 mg/m2) plus oral dexamethasone (6 mg/m2 per day for 7 days) during the second year of treatment. The primary endpoint was difference in 5-year event-free survival between the experimental group and the control group for both the low-risk and intermediate-to-high-risk cohorts, with a non-inferiority margin of 0·05 (5%). The analysis was by intention to treat. This trial is registered with the Chinese Clinical Trial Registry, ChiCTR-IPR-14005706. FINDINGS: Between Jan 1, 2015, and Feb 20, 2020, 6141 paediatric patients with newly diagnosed acute lymphoblastic leukaemia were registered to this study. Approximately 1 year after diagnosis and treatment, 5054 patients in continuous remission were randomly assigned, including 2923 (1442 in the control group and 1481 in the experimental group) with low-risk acute lymphoblastic leukaemia and 2131 (1071 control, 1060 experimental) with intermediate-to-high risk acute lymphoblastic leukaemia. Median follow-up for patients who were alive at the time of analysis was 3·7 years (IQR 2·8-4·7). Among patients with low-risk acute lymphoblastic leukaemia, no difference was observed in 5-year event-free survival between the control group and the experimental group (90·3% [95% CI 88·4-92·2] vs 90·2% [88·2-92·2]; p=0·90). The one-sided 95% upper confidence bound for the difference in 5-year event-free survival probability was 0·024, establishing non-inferiority. Among patients with intermediate-to-high-risk acute lymphoblastic leukaemia, no difference was observed in 5-year event-free survival between the control group and the experimental group (82·8% [95% CI 80·0-85·7] vs 80·8% [77·7-84·0]; p=0·90), but the one-sided 95% upper confidence bound for the difference in 5-year event-free survival probability was 0·055, giving a borderline inferior result for those in the experimental group. In the low-risk cohort, we found no differences in the rates of infections, symptomatic osteonecrosis, or other complications during the second year of maintenance treatment between patients in the control and experimental groups. Patients with intermediate-to-high-risk acute lymphoblastic leukaemia in the control group were more likely to develop grade 3-4 pneumonia (26 [2·4%] of 1071 vs ten [0·9%] of 1060) and vincristine-related peripheral neuropathy (17 [1·6%] vs six [0·6%]) compared with the experimental group. Incidence of grade 5 fatal infection was similar between the control group and the experimental group in both the low-risk cohort (two [0·1%] of 1442 vs five [0·3%] of 1481) and intermediate-to-high risk cohort (six [0·6%] of 1071 vs five [0·5%] of 1060). INTERPRETATION: Vincristine plus dexamethasone pulses might be omitted beyond 1 year of treatment for children with low-risk acute lymphoblastic leukaemia. Additional studies are needed for intermediate-to-high-risk acute lymphoblastic leukaemia.

RESUMO

OBJECTIVES: Single nucleotide variants (SNVs) in vascular endothelial growth factor A (VEGFA) and VEGFA receptor (KDR) genes confer different inherited abilities in angiogenesis (AG) pathway. We aimed in the present study to evaluate influence of six VEGFA and four KDR SNVs in clinical features and survival of diffuse large B-cell lymphoma (DLBCL) patients. METHODS: One hundred and sixty-eight DLBCL patients diagnosed between June 2009-September 2014 were enrolled in the study. Patients were homogeneously treated with R-CHOP. Genotypes were identified in genomic DNA by real-time polymerase chain reaction. RESULTS: Patients with VEGFA -634CC and +936CT or TT genotypes were at increased risk of showing grade III / IV toxicities and not achieving complete remission with treatment, and shorter event-free and overall survival were seen in patients with VEGFA -1154GA or AA genotype and VEGFA ATAGCC haplotype. CONCLUSION: Our data suggest that inherited abnormalities in AG's gene modulate clinical features and prognosis of DLBCL patients homogeneously treated with R-CHOP.

RESUMO

Corticosteroid administration prior to the application of chemotherapy in small animal lymphoma patients is a concern, as it is discussed to negatively influence the therapeutic outcome due to corticosteroid-induced drug resistance. Using feline lymphoma cell lines FT-1 and MS4 we have shown, that prednisolone pre-treatment alters the susceptibility of these cells towards doxorubicin or vincristine treatment in vitro. The observed effect was negative as for the killing potential and it was cell line and drug (doxorubicin or vincristine) dependent. Furthermore, increase in mRNA expression of selected proteins with multidrug resistance potential (MDR1, BCRP, LRP, MT) was observed after prednisolone pre-treatment. Administration of chemical inhibitors of these proteins did not lead to reversal in sensitivity of tested cell lines to doxorubicin or vincristine.

RESUMO

RATIONALE: B-lymphoblastic lymphoma (B-LBL) with BCR/ABL mutation (Ph+ B-LBL) is a rare type of cancer in both childhood and adults. Its clinical manifestations are similar to those of other types lymphoma. However, the targeted therapy can substantially improve the outcome of Ph+ B-LBL. PATIENT CONCERNS: A 19-year-old male with blood type O, Rh+ was admitted into our hospital on August 14, 2018, due to a recurrent fever and hypocytosis for 6 months. DIAGNOSES: Routine blood exam showed pancytopenia. Bone marrow sample flow cytometry (FCM) exam showed abnormal cells were 2.27% of the nucleated cells, and was classified as the abnormal early B-lineage lymphoblastic cells. FISH testing showed the BCR/ABL positive cells were 13.6%. Karyotype analysis showed the 46, XY, t(9;22)(q34;q11). Molecular analysis of BCR/ABL mutation on ABL kinase showed that BCR/ABL T315I mutation. Patient was diagnosed with B-LBL with BCR/ABL mutation (Ph+ B-LBL). INTERVENTIONS: The patient was given chemotherapy with VDPI regimen (Vinorelbine, daunorubicin, prednisone, imatinib). OUTCOMES: The patient achieved complete remission after 2 courses' treatment, followed by one course of clarithromycin regimen and another two courses of VDPI regimen. Patient remains in complete remission as of March 10, 2021. LESSONS: In B-LBL, a BCR/ABL mutation can happen in some of these patients. It is important to guide the pathologist to perform appropriate gene mutation detection, in addition to routine Immunohistochemistry test, to ensure an accurate diagnosis and use the targeted agent for treatment. According to the literature and our results, it seems that intensive chemotherapy plus TKI regimen is effective in inducing complete remission, and allo-SCT should be used as a long-term strategy.

RESUMO

Chemotherapy for non-Hodgkin lymphoma (NHL) in the hemodialysis (HD) patient is a challenging situation. Because many drugs are predominantly eliminated by the kidneys, chemotherapy in the HD patient requires special considerations concerning dose adjustments to avoid overdose and toxicities. Conversely, some drugs are removed by HD and may expose the patient to undertreatment, therefore the timing of drug administration in relation to HD sessions must be carefully planned. Also, the metabolites of some drugs show different toxicities and dialysability as compared with the parent drug, therefore this must also be catered for. However, the pharmacokinetics of many chemotherapeutics and their metabolites in HD patients are unknown, and the fact that NHL patients are often treated with distinct multiagent chemotherapy regimens makes the situation more complicated. In a realm where uncertainty prevails, case reports and case series reporting on actual treatment and outcomes are extremely valuable and can aid physicians in decision making from drug selection to dosing. We carried out an exhaustive review of the literature and adopted 48 manuscripts consisting of 66 HD patients undergoing 71 chemotherapy regimens for NHL, summarized the data, and provide recommendations concerning dose adjustments and timing of administration for individual chemotherapeutics where possible. The chemotherapy regimens studied in this review include, but are not limited to, rituximab, cyclophosphamide + vincristine + prednisolone (CVP) and cyclophosphamide + doxorubicin + vincristine + prednisolone (CHOP)-like regimens, chlorambucil, ibrutinib, bendamustine, methotrexate, platinum compounds, cytarabine, gemcitabine, etoposide, ifosfamide, melphalan, busulfan, fludarabine, mogamulizumab, brentuximab vedotin, and 90 Y-ibritumomab tiuxetan.

RESUMO

BACKGROUND/AIM: Primary adrenal lymphoma (PAL) is rare and aggressive. The aim of this retrospective study was to compare the results of surgery and chemotherapy compared to chemotherapy alone for the treatment of this condition. PATIENTS AND METHODS: Sixteen patients, 10 men and 6 women of a median age of 63 years (IQR=56-70.5 years), admitted for the treatment of PAL, were retrospectively reviewed. Six patients (37.5%) underwent surgical resection of the mass followed by CHOP (cyclophosphamide, doxorubicin, vincristine, bleomycin and prednisone) - based chemotherapy (Group A). Ten patients (62.5%) underwent chemotherapy alone, consisting of CHOP alone in one case and Rituximab-CHOP (R-CHOP) in 9 cases (Group B). As primary study endpoints of the study, overall survival (OS) and progression-free survival (PFS) were considered. RESULTS: At two years follow-up, OS was 50% in Group A and 60% in group B (p=0.69). The PFS was 50% in group A and 30% in group B (p=0.42). CONCLUSION: PAL exhibits overall a dismal prognosis. Chemotherapy remains the most appropriate treatment, although unable to ensure long-term survival. Surgery combined with chemotherapy is ineffective in improving survival and may, at best, have a limited role in relieving the pain related to the local mass effect.

RESUMO

The application of positron emission tomography (PET)-computed tomography (CT) in treatment response evaluation has increased in diffuse large B-cell lymphoma (DLBCL), although its predictive value is controversial. We retrospectively analyzed the rate of false-positive PET-CTs performed as interim (n = 94) and end-of-treatment (n = 8) assessments among 102 DLBCL patients treated during 2010-2017 at Oulu University Hospital. In PET-CT Deauville score ≥4 was regarded as positive. A biopsy was performed on 35 patients, and vital lymphoma tissue was detected from nine patients. Positive biopsy findings were associated with poor disease outcomes in this study. This difference was statistically significant: 2-year failure-free survival (FFS) was 44% in patients with a positive biopsy versus 83% for those with a negative biopsy (p = 0.003). The corresponding overall survival (OS) rates were 53% versus 95% (p = 0.010). In the multivariate analyses, a negative biopsy was an independent protective factor in FFS (Hazard Ratio (HR) 0.093 (95% confidence interval [CI] 0.017-0.511); p = 0.006) unrelated to the International Prognostic Index (IPI) (HR 1.139 [95% CI 0.237-5.474] p = 0.871) or stage (HR 1.365 [95% CI 0.138-13.470]; p = 0.790). There was no statistically significant difference in OS according to the PET results, but the FFS rate was significantly higher in patients with a negative PET. The value of PET-CT as an evaluation method suffers from a high false-positive rate, and it is inadequate alone for the justification of treatment decisions. Biopsy results provide more reliable prognostic information for the evaluation of treatment response and outcome and should be used to assess patients with positive PET-CT scans.

RESUMO

Diffuse large B cell lymphoma (DLBCL), the most common type of Non-Hodgkin lymphoma (NHL), comprises a heterogeneous group of diseases with different biology, clinical presentations, and response to treatment. R-CHOP remains the mainstay of therapy and can achieve long-term disease control in nearly 90% of patients presenting with limited-stage and in up to 60% of those presenting with advanced stages. Advances on the understanding of the genetic landscape and molecular features of DLBCL have identified high-risk subsets with poor outcomes to chemo-immunotherapy that are actively being studied in clinical trials. Novel therapies could potentially improve outcomes for patients with high-risk disease. Studies evaluating risk-adapted therapy based on classification by cell of origin (COO) and molecular features are ongoing. Developments in the fields of immunotherapy, mostly with adoptive T-cell therapy, have significantly improved the outcomes of patients with relapsed refractory disease. In this review, we will summarize the recent data and discuss ongoing efforts to improve DLBCL treatment in the frontline and relapsed refractory settings.

RESUMO

The long-term effects of pegfilgrastim administered in the first cycle of chemotherapy in day-to-day practice remain unclear. We retrospectively identified 114 patients aged ≥ 70 years with diffuse large B-cell lymphoma who received a rituximab-cyclophosphamide-doxorubicin-vincristine-prednisolone (R-CHOP) regimen in our institution. Twenty-six patients received pegfilgrastim (pegfilgrastim group); of the 88 patients scheduled to receive conventional granulocyte-colony stimulating factor (G-CSF) when their neutrophil count decreased (neut-adjusted-G group), conventional G-CSF was ultimately administered to 57. During the first cycle of R-CHOP, the incidence of febrile neutropenia was lower in the pegfilgrastim group than in the neut-adjusted-G group (0% vs. 18%, p = 0.020). Throughout all cycles, a higher proportion of patients exhibited sustained relative dose intensity (≥ 80%) in the pegfilgrastim group than in the neut-adjusted-G group (25% vs. 4.0%, p = 0.008). A lower proportion of patients received a reduced dose in the second cycle in the pegfilgrastim group than in the neut-adjusted-G group (0% vs. 10%, p = 0.116). Although the differences were not significant, the pegfilgrastim group showed higher progression-free survival and overall survival than the neut-adjusted-G group. Adequate prevention of febrile neutropenia using pegfilgrastim during the first cycle of R-CHOP may contribute to avoidance of dose intensity reduction in all cycles.

RESUMO

BACKGROUND: Acute leukemia with mixed-phenotype blasts is associated with poor outcomes. There are no standard treatment regimens. Due to disease heterogeneity, controversy exists over whether an AML-based, ALL-based, or a combined (hybrid) AML/ALL-based regimen is most appropriate. MATERIALS AND METHODS: We conducted a single-center, retrospective case series review of patients with acute leukemia with mixed phenotype blasts as described by the European Group for Immunological Characterization of Leukemia (EGIL) or the 2008 WHO classification. Patients were treated from November 2014 and December 2019 with the combination chemotherapy regimen FLAG-idarubicin-vincristine-prednisone with or without rituximab. Outcomes included induction response, time to transplant, time to relapse, overall survival, time to neutrophil or platelet recovery, infection, and duration of hospitalization. RESULTS: The median age was 68 years (range 21-77). Six patients (87.5 %) had unfavorable/complex cytogenetics. All patients achieved a complete remission (CR) or complete remission with incomplete hematologic recovery (CRi). Estimated 1-year overall survival was 85.7 %. There were no deaths during induction, with a 22 day median duration of hospitalization for induction. CONCLUSION: The combination of FLAG, idarubicin, vincristine, and prednisone (FLAG-VIPR) demonstrated favorable induction responses in a disease state with historically poor outcomes and should be studied in a prospective clinical trial.

RESUMO

BACKGROUND: To improve the long-term tumour control in early, unfavourable Hodgkin Lymphoma, the German Hodgkin Study Group (GHSG) HD14 trial compared four cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with an intensified chemotherapy regimen consisting of two cycles of escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (escalated BEACOPP) plus two cycles of ABVD. The final analysis of the trial showed a significant advantage in terms of freedom from treatment failure (difference 7·2% [95% CI 3·8-10·5] at 5 years) for patients who received two cycles of escalated BEACOPP and two cycles of ABVD. However, there was no difference in overall survival between the two groups. To evaluate long-term efficacy and toxicity of this strategy, we did a follow-up analysis. METHODS: Patients aged 18-60 years with performance status of 2 or less and primary diagnosis of early, unfavourable Hodgkin lymphoma (all histologies) were included in an international, randomised, open-label, phase 3 trial. Patients were randomly assigned to receive four cycles of ABVD (ABVD group) or two cycles of escalated BEACOPP and two cycles of ABVD (2 + 2 group), both groups also received 30 Gy involved field radiotherapy. The ABVD dosing regimen was doxorubicin 25 mg/m2 (days 1 and 15), bleomycin 10 mg/m2 (days 1 and 15), vinblastine 6 mg/m2 (days 1 and 15), and dacarbazine 375 mg/m2 (days 1 and 15), repeated on day 29. The escalated BEACOPP dosing regimen was cyclophosphamide 1250 mg/m2 (day 1), doxorubicin 35 mg/m2 (day 1), etoposide 200 mg/m2 (days 1-3), procarbazine 100 mg/m2 (days 1-7), prednisone 40 mg/m2 (days 1-14), vincristine 1·4 mg/m2 (day 8; maximum 2 mg), and bleomycin 10 mg/m2 (day 8), repeated on day 22. After closure of the ABVD group according to prespecified rules, patients were assigned to receive two cycles of escalated BEACOPP and two cycles of ABVD (non-randomised 2 + 2 group), which continued until the end of the predefined 5-year recruitment period. In this prespecified long-term follow-up analysis, we aimed to evaluate the secondary endpoints progression-free survival, overall survival, and long-term toxicity. To this end, we did a descriptive intention-to-treat analysis of all qualified HD14 patients and on the predefined subsets of randomised qualified HD14 patients and patients in the non-randomised 2 + 2 group. The trial was registered on the International Standard Randomised Controlled Trial database, 04761296. FINDINGS: Between Jan 28, 2003, and Dec 29, 2009, 1686 patients were randomly assigned to the ABVD group (847 [50·2%] patients) and the 2 + 2 group (839 [49·8%] patients). 370 additional patients were recruited to the non-randomised 2 + 2 group. 1550 (92%) randomly assigned patients (median observation time 112 months [IQR 80-132]) and 339 (92%) patients in the non-randomised 2 + 2 group (median observation time 74 months [58-100]) were included in the qualified analysis set. 10-year overall survival in the randomly assigned patients was 94·1% (95% CI 92·0-95·7) for the ABVD group and 94·1% (91·8-95·7) for the 2 + 2 group (HR 1·0 [95% CI 0·6-1·5]; p=0·88). 8-year overall survival in the non-randomised 2 + 2 group was 95·1% (95% CI 91·6-97·2). 10-year progression-free survival in the randomly assigned patients was 85·6% (95% CI 82·6-88·1) for the ABVD group and 91·2% (88·4-93·3) for the 2 + 2 group (HR 0·5% [95% CI 0·4-0·7]; p=0·0001), accounting for a significant difference of 5·6% (95% CI 1·9-9·2) favouring the 2 + 2 group (p=0·0001). In the non-randomised 2 + 2 group, 8-year progression-free survival was 94·5% (95% CI 91·1-96·6). Standardised incidence ratios of second primary malignancies were similar between the ABVD group (2·3 [95% CI 1·6-3·1]) and the 2 + 2 group (2·5 [1·8-3·4]; Gray's p=0·80). Standardised incidence ratio of second primary malignancies was 3·1 (95% CI 1·7-5·0) in the non-randomised 2 + 2 group. INTERPRETATION: This long-term analysis confirms superior tumour control in the 2 + 2 group compared with the ABVD group without translating into an overall survival difference. At longer follow-up, there is no difference regarding second primary malignancies between groups. In conclusion, the 2 + 2 regimen spares a significant number of patients from the burden of relapse and additional treatment without increased long-term toxicity.

RESUMO

We present long-term combined results of two clinical trials implementing R-MACLO-IVAM induction followed by thalidomide or rituximab maintenance in 44 patients with untreated mantle cell lymphoma (MCL). The first 22 patients (UM-MCL1 ClinicalTrials.gov identifier NCT00450801) received maintenance with thalidomide (200 mg daily until relapse/intolerable toxicity) and a subsequent cohort of 22 patients (UM-MCL2 ClinicalTrials.gov identifier NCT00878254) received rituximab (375 mg/m2 IV weekly × 4, repeated every 6 months for 3 years). Considering all 44 patients, 41 (93.2%) achieved complete response (CR), two (4.5%) partial response (PR), and one (2.3%) was not evaluated for response. With a median follow up of 7.2 years (range < 1 month to 16 years), the 5-year progression-free survival (PFS) was 55.6% (95% CI: 38.9%-69.4%) and median PFS 7.9 years (95% CI: 3.7-11 years). The 5-year OS was 83.3% (95% CI: 68.1%-91.7%) and median OS was not reached. Patients with blastic variant (n = 6) had a 5-year PFS and OS of 20.8% and 60%, respectively. Myelosuppression was the most common adverse event during immunochemotherapy. Long-term treatment-related mortality was 6.8%. Note, R-MACLO-IVAM followed by maintenance therapy is an effective regimen to induce long-term remission in MCL without need for consolidation with ASCT.

RESUMO

The phase 2 CAVALLI (NCT02055820) study assessed efficacy and safety of venetoclax, a selective B-cell lymphoma-2 (Bcl-2) inhibitor, with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in first-line (1L) diffuse large B-cell lymphoma (DLBCL), including patients demonstrating Bcl-2 protein overexpression by immunohistochemistry (Bcl-2 IHC+). Eligible patients were ≥18 years of age and had previously untreated DLBCL, Eastern Cooperative Oncology Group performance status ≤2, and International Prognostic Index 2 to 5. Venetoclax 800 mg (days 4-10, cycle 1; days 1-10, cycles 2-8) was administered with rituximab (8 cycles) and cyclophosphamide, doxorubicin, vincristine, and prednisone (6-8 cycles) in 21-day cycles. Primary end points were safety, tolerability, and research_plete response (CR) at end of treatment (EOT). Secondary end points were progression-free survival (PFS) and overall survival. Comparative analyses used covariate-adjusted R-CHOP controls from the GOYA/BO21005 study, an appropriate contemporary benchmark for safety and efficacy. Safety and efficacy analyses included 206 patients. CR rate at EOT was 69% in the overall population and was maintained across Bcl-2 IHC+ subgroups. With a median follow-up of 32.2 months, trends were observed for improved investigator-assessed PFS for venetoclax plus R-CHOP in the overall population (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.43-0.87) and Bcl-2 IHC+ subgroups (HR, 0.55; 95% CI, 0.34-0.89) vs R-CHOP. Despite a higher incidence of grade 3/4 hematologic adverse events (86%), related mortality was not increased (2%). Chemotherapy dose intensity was similar in CAVALLI vs GOYA. The addition of venetoclax to R-CHOP in 1L DLBCL demonstrates increased, but manageable, myelosuppression and the potential of improved efficacy, particularly in high-risk Bcl-2 IHC+ patient subgroups.

RESUMO

RATIONALE: Oral cancer often causes secondary primary cancers in the upper gastrointestinal tract. However, there are no reports of secondary primary cancers in patients with oral squamous cell carcinoma and malignant lymphoma of the small intestine. This report describes a case of metachronous multiple primary cancers of the tongue and small intestine malignant lymphoma. PATIENTS CONCERNS: The patient was admitted to our department with the chief complaint of pain in the right tongue. Partial tongue resection and supraomohyoid neck dissection were performed. One year after surgery, the patient experienced abdominal pain and bloody stools. DIAGNOSIS: Diffuse large B-cell lymphoma (DLBCL) was diagnosed via histological examination. INTERVENTIONS: A terminal ileum resection was performed. Postoperatively, the patient received 6 courses of rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP). OUTCOMES: Five years after his initial diagnosis, there is no evidence of recurrence, metastasis, or other primary cancer. LESSONS: Oral cancer patients should always be followed up owing to a possibility of malignant tumors in other areas.

RESUMO

As the aging society advances, the number of non-Hodgkin lymphoma (NHL) patients is increasing. Aged relapsed or refractory (r/r) NHL patients have limited treatment options. Therefore, a safe and effective regimen is urgently needed for these patients. Thus, we originally developed the MTX-HOPE (methotrexate, hydrocortisone, vincristine, sobuzoxane, and etoposide) regimen for r/r NHL and validated the safety and efficacy of this regimen in a clinical setting. We analyzed the data of 42 r/r NHL patients who received MTX-HOPE in this single-center retrospective cohort study. The median age of the patients was 81 years. The overall response rate was 45.3%. The median overall survival (OS) was 7 months, the one-year OS was 43.7%, and the two-year OS was 40.8%. Grade ≥3 neutropenia and renal dysfunction were observed in 47.6% and 11.9% of patients, respectively, and treatment-related death were not observed. Appropriate supportive care enabled these patients to continue the MTX-HOPE regimen. The proportion of patients who needed hospitalization during MTX-HOPE therapy was only 21.4%. Multivariable analyses with the Cox proportional hazards model revealed that both OS and progression-free survival (PFS) were significantly influenced by high Ki-67 expression in pathology, with response to the MTX-HOPE regimen after three to five cycles as a time-dependent covariate. Our results suggest that MTX-HOPE therapy can be an option for non-aggressive r/r NHL patients. To validate MTX-HOPE therapy, further prospective investigation is needed.

RESUMO

High-dose methotrexate (HD-MTX) at 3 g/m2 is one of the strategies for central nervous system (CNS) prophylaxis in the first-line treatment of aggressive lymphomas, especially in diffuse large B cell lymphoma patients with high-risk CNS-International Prognostic Index. The objective of our study was to retrospectively analyze the safety of 2 cycles of systemic HD-MTX administered as an ambulatory regimen. Between January 2013 and December 2016, 103 patients were carefully selected on 6 criteria, including age < 60, albumin > 34, performance status 0 or 1, normal renal and hepatic functions, good understanding of practical medical guidance, and no loss of weight. Strict procedures of HD-MTX infusion were observed including alkalinization, urine pH monitoring, and leucovorin rescue. Renal and hepatic functions were monitored at days 2 and 7. MTX clearance was not monitored. Toxicities and grades of toxicity were collected according to the NCI-CTCAE (version 4.0). Among the 103 selected patients, 92 (89%) patients successfully completed the planned 2 cycles of HD-MTX on an outpatient basis. Eleven patients completed only 1 cycle, 3 because of lymphoma progression and 8 because of toxicity including 3 grade II hepatotoxicity, 2 grade I/II renal toxicity, 1 grade III neutropenia, 1 active herpetic infection, and 1 grade III ileus reflex. Reported adverse events (AE) included 92 (84%) grade I/II and 18 (16%) grade III/IV. Grade III hepatotoxicity, mostly cytolysis, was the most frequent AE observed with 8 (8%) events. Grade III/IV hematologic toxicities concerned 9 patients with 8 grade III/IV neutropenia and 1 thrombocytopenia. Renal toxicity was rare, mild, and transient, observed with 4 (4%) grade I/II events. Ambulatory administration of HD-MTX at 3 g/m2 without MTX clearance monitoring is safe with strict medical guidance. It requires careful selection of patients before administration, and a renal and hepatic monitoring after the administration.

RESUMO

The prognosis of elderly patients diagnosed with diffuse large B cell lymphoma (DLBCL) is considered to be clearly inferior to that of younger patients. Besides tumor biology and comorbidities, treatment selection due to an assumed reduced tolerability may contribute to this difference. With increasingly more patients diagnosed at advanced age, current treatment selections need to be reviewed carefully. Hence, we analyzed the results of patients above the age of 70 in whom a diagnosis of DLBCL was made. Whereas patients up to 80 were frequently selected for and were able to tolerate standard treatment (86% intended use, 74% completion), patients above the age of 80 years were not only treated more cautiously (67 and 60%, respectively) but did show inferior response to treatment with standard treatment (CR rate for intended R-CHOP use 64% vs. 43%). However, on an individual level, patients receiving and completing standard treatment obtained results that resemble the results of younger patients, irrespective if aged more than 80 and impose superior to prior reports in this age cohort. Median PFS for the entire group of patients was 3.44 years, with 4.83 years for patients below 80 and only 1.09 years for patients above the age of 80. The corresponding figures for OS were 7.38 years (estimated); after 2 years, OS was 81% in the younger cohort in contrast to 68% in patients > 80 years. However, for patients not planned to receive or not tolerating R-CHOP, results remain poor; tailored approaches for these patients are required.

RESUMO

Treatment with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) or escalated(e)-BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) remains the international standard of care for advanced-stage classical Hodgkin lymphoma (HL). We performed a retrospective, multicentre analysis of 221 non-trial ("real-world") patients, aged 16-59 years, diagnosed with advanced-stage HL in the Anglia Cancer Network between 2004 and 2014, treated with ABVD or eBEACOPP, and compared outcomes with 1088 patients in the Response-Adjusted Therapy for Advanced Hodgkin Lymphoma (RATHL) trial, aged 18-59 years, with median follow-up of 87.0 and 69.5 months, respectively. Real-world ABVD patients (n=177) had highly similar 5-year progression-free survival (PFS) and overall survival (OS) compared with RATHL (PFS 79.2% vs 81.4%; OS 92.9% vs 95.2%), despite interim positron-emission tomography-computed tomography (PET/CT)-guided dose-escalation being predominantly restricted to trial patients. Real-world eBEACOPP patients (n=44) had superior PFS (95.5%) compared with real-world ABVD (HR 0.20, p=0.027) and RATHL (HR 0.21, p=0.015), and superior OS for higher-risk (international prognostic score ≥3 [IPS 3+]) patients compared with real-world IPS 3+ ABVD (100% vs 84.5%, p=0.045), but not IPS 3+ RATHL patients. Our data support a PFS, but not OS, advantage for patients with advanced-stage HL treated with eBEACOPP compared with ABVD and suggest higher-risk patients may benefit disproportionately from more intensive therapy. However, increased access to effective salvage therapies might minimise any OS benefit from reduced relapse rates after frontline therapy.

RESUMO

We conducted a nationwide retrospective analysis of 116 hepatitis B virus (HBV) surface antigen (HBsAg)-positive patients with diffuse large B-cell lymphoma (DLBCL) and 278 HBsAg-negative patients with DLBCL, as a control cohort, who received rituximab-containing regimens as an induction chemotherapy at 30 Japanese medical centers between January 2004 and December 2014. Hepatitis was defined as an absolute serum alanine aminotransferase (ALT) level of ≥100 U/L. HBV reactivation-related hepatitis was defined as hepatitis with an absolute serum HBV DNA level of ≥3.3 log IU/mL or an absolute increase of ≥2 log compared with the baseline value. HBsAg-positive patients were divided into three groups based on anti-HBV prophylactic therapy: no nucleos(t)ide analogue (non-NA, n = 9), lamivudine (LAM, n = 20), and entecavir (ETV, n = 87). The 4-year cumulative incidence (CI) of hepatitis in HBsAg-positive and HBsAg-negative patients was 21.1% and 14.6% (P = .081), respectively. The 4-year CI of HBV reactivation-related hepatitis was higher in HBsAg-positive patients than in HBsAg-negative patients (8.0% vs 0.4%; P < .001). Among HBsAg-positive patients, the 4-year CI of HBV reactivation-related hepatitis was the highest in the non-NA group (33.3%), followed by the LAM (15.0%) and ETV (3.8%) groups (P < .001). Of note, 3 non-NA patients (33%) and 1 LAM patient (5%) (but no ETV patients) died due to HBV hepatitis. Based on Cox multivariate analysis, HBsAg positivity was not associated with poor overall survival. Prophylactic use of ETV would reduce the occurrence of HBV reactivation-related hepatitis and mortality in HBsAg-positive DLBCL patients receiving rituximab-containing chemotherapy.
