Characteristics and outcomes of children, adolescents and young adults with relapsed/refractory non-hodgkin lymphoma undergoing autologous stem cell transplant.

ABSTRACT:

Background

There is paucity of data regarding outcomes of children, adolescents and young adults (CAYA) patients with non-Hodgkin lymphoma (NHL) undergoing autologous stem cell transplantation (ASCT).

Methods

Patients aged 0-39 years undergoing first ASCT for NHL at MD Anderson Cancer Center between 2000 and 2020 were analyzed.

Results

Two hundred twenty-one patients were included in the analysis, 129 (58%) were male and the median age was 32 (range 6-39) years. The most common histological subtypes were diffuse large B cell lymphoma (DLBCL) (44%), T-NHL (19%) and primary mediastinal B-Cell lymphoma (PMBCL) (19%). Younger patients (age ≤ 25) had lower incidence of DLBCL and higher incidence of PMBCL and T-NHL compared to older patients (age > 25) (P = 0.02). None of the younger patients had double hit (DH)/double expressor (DE) DLBCL, compared to 14 patients in the older age group (18%, P = 0.07). Considering the three main aggressive NHL subtypes (DLBCL, PMBCL and T-NHL), younger patients had numerically better 15-year post-transplant progression free survival (PFS) (67% vs. 54%) and overall survival (OS) (71% vs. 62%) compared to older patients, yet these differences did not reach statistical significance (P = 0.19 and P = 0.24, respectively). In multivariate analysis, not achieving a CR prior to ASCT was independently predictive of worse PFS [partial remission (PR) (HR, 3.9); stable disease (SD) (HR, 18.0), P = 0.03] and of worse OS [PR (HR, 4.2), SD (HR, 6.5) and progressive disease (HR, 4.7), P < 0.0001]. DH/DE status was an independent adverse predictor of PFS in multivariate analysis (HR 5.8, p = 0.03). Ten patients (4.5%) (all aged > 25 years) developed second primary malignancies (SPM), at a median of 34.4 (range, 1.0-196.6) months after ASCT, and SPM was the cause of death in five (50%) of them.

Conclusions

CAYA NHL patients aged ≤ 25 years who received ASCT presented a distinct NHL histology as compared to older CAYA patients, and none in this younger age group had DH/DE DLBCL. We observed a trend towards improved PFS and OS in younger patients. Disease status at ASCT was predictive of both PFS and OS. DH/DE status was an adverse predictor of PFS.

Project description:BackgroundThe prognosis of Hodgkin lymphoma (HL) relapsing post autologous transplant (AuSCT) is poor. Even with novel therapies, only approximately 20%-25% of patients attain complete remissions, with a median progression-free survival (PFS) of approximately 5-15 months. Lenalidomide has been shown to have activity in relapsed HL. We retrospectively analyzed the outcomes of patients with relapsed HL post AuSCT treated with lenalidomide alone or in combination with dexamethasone at our center.Patients and methodsRecords of 143 patients transplanted from November 2007 to October 2021 were reviewed. Of these patients, 41 (28%) relapsed, and 16 (39%) received lenalidomide alone or in combination with dexamethasone. Data collected included demographic, pathological, staging, and prior therapy details. Lenalidomide was administered at 10-25 mg/day on an intermittent or continuous schedule alone or in combination with dexamethasone (20-40 mg weekly). Response was assessed using PET-CT scan in accordance with Lugano criteria. Standard definitions were used for response, PFS, and overall survival (OS). Toxicities were graded using Common Terminology Criteria for Adverse Events version 5.0. Statistical analysis was done using SPSS Version 21.ResultsThe median age of the patients was 25.5 years, and 10 were males. Eleven (69%) had advanced disease, and 7 (44%) were refractory to last systemic therapy. Nine patients received lenalidomide alone and 7 with dexamethasone. Four (25%) had complete response, and another four (25%) had partial response, with an overall response rate of 50%. The 3-year PFS and OS were 31% and 38%, respectively. Grade III/IV toxicities were only hematological, neutropenia and thrombocytopenia in four and three patients, respectively. No therapy-related deaths were recorded.ConclusionsLenalidomide alone or in combination with dexamethasone is a safe and effective therapy for relapsed HL post AuSCT and results in durable response and long-term survival in approximately one-third of the patients. However, these results needs verification in larger prospective studies.

Project description:BackgroundNo consensus exists regarding the use of radiotherapy (RT) in conjunction with high-dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) for patients with relapsed/refractory classical Hodgkin lymphoma (HL). The objectives of the current study were to characterize practice patterns and assess the efficacy and toxicity of RT at 2 major transplantation centers.MethodsEligible patients underwent HDC/ASCT from 2006 through 2015 using the combination of either carmustine (BCNU), etoposide, cytarabine, and melphalan (BEAM) or cyclophosphamide, BCNU, and etoposide (CBV).ResultsFor the cohort of 189 patients, the 4-year overall survival rate was 80%, the progression-free survival rate was 67%, and the local control (LC) rate was 68%. RT was used within 4 months of ASCT for 22 patients (12%) and was given more often for disease that was early stage, primary refractory, or [18 F]fluorodeoxyglucose (FDG)-avid at the time of HDC/ASCT. Disease recurrence occurring after HDC/ASCT was associated with primary refractory disease and FDG-avidity at the time of HDC/ASCT. RT was not found to be associated with LC, progression-free survival, or overall survival on univariate analysis. In a model incorporating primary refractory HL and FDG-avid disease at the time of HDC/ASCT, RT was found to be associated with a decreased risk of local disease recurrence (hazard ratio, 0.3; P = .02). In patients with primary refractory HL and/or FDG-avid disease at the time of HDC/ASCT, the 4-year LC rate was 81% with RT versus 49% without RT (P = .03). There was one case of Common Terminology Criteria for Adverse Events grade ≥ 3 RT-related toxicity (acute grade 3 pancytopenia).ConclusionsIn patients undergoing ASCT for relapsed/refractory HL, peritransplantation RT was used more often for disease that was early stage, primary refractory, or FDG-avid after salvage conventional-dose chemotherapy. RT was associated with improved LC of high-risk localized disease and was well tolerated with modern techniques. Cancer 2017;123:1363-1371. © 2016 American Cancer Society.
