Long Term Outcomes of Patients with Aggressive T-Cell Non-Hodgkin Lymphoma Undergoing Allogeneic Stem Cell Transplantation: Retrospective Results from a Single Center

Background: Mature T cell and NK cell neoplasms collectively known as peripheral T-cell lymphomas (PTCL) comprise 15-20% of Non-Hodgkin lymphomas in adults and have a poor prognosis with a 5-year survival of less than 30% for the most aggressive subtypes. Allogeneic HCT (allo-HCT) is offered to eligible patients as a potentially curative modality in the salvage setting or in high risk patients to consolidate an initial response to frontline therapy. There are few studies that report clinical outcomes derived from large sample size and long-term follow up data. Methods: We retrospectively reviewed medical records of 87 consecutive patients with PTCL including transformed mycosis fungoides and NK/T-cell lymphoma without prior autologous transplant who underwent allo-HCT at City of Hope from January 2000 to June 2018 after IRB approval was obtained. Descriptive statistics were used to summarize baseline patient demographic, treatment, and disease characteristics. Kaplan-Meier curves and the log-rank test were used to evaluate the overall survival (OS) and progression-free survival (PFS). Cumulative incidences of time to relapse and time to non-relapse mortality (NRM) were calculated with relapse and NRM as competing risks. Cumulative incidences of acute and chronic GVHD were calculated as time to onset of GVHD with relapse and death as competing events for GVHD. Results: 87 patients were included for the analysis. Median age at the time of allo-HCT was 49 years (range 2-70 years). Histologies were PTCL-NOS (n=21); transformed CTCL (n=19); NK T-cell lymphoma (n=17); AITL (n=15), ALCL (n=7); gamma delta T-cell lymphoma (n=6) and other rare subtypes (n=2). None of the patients had a prior auto transplant. 42 patients (48%) received myeloablative conditioning, with the majority of patients receiving FTBI based conditioning (n=39) and three patients received BEAM regimen for conditioning. 45 patients (52%) received reduced intensity conditioning; fludarabine/melphalan based-conditioning was the most common regimen used (n=39). Sibling HCT was performed in 47 patients (54%), while MUD HCT was performed in 36 patients (41%) with fully matched HLA unrelated donor in 15 (17%) and HLA mismatched in 21 (24%) patients; 4 (5%) received haploidentical HCT. GVHD prophylaxis consisted of tacrolimus/sirolimus (n=54), tacrolimus/sirolimus/MTX (n=11), tacrolimus or cyclosporine/MTX (n=7), tacrolimus or cyclosporine/MMF (n=7), post-transplant cyclophosphamide/tacrolimus/MMF (n=5) and other (n=3). Source of stem cells was PBSC in 77 (88%), bone marrow in 5 (6%), and cord blood in 5 (6%) patients. At the time of allo-HCT, there were a total of 25 (29%) patients in complete remission (CR1 n=15, CR2+ n=10), 25 (29%) patients in partial remission 22 (25%) with induction failure and 14 (16%) with relapsed disease. The median follow-up among survivors was 6.9 years (range 1.1-15.5). The 5- and 10-year PFS was 47% (95% CI: 36%-58%) and 38% (95% CI: 26%-50%), respectively. The 5- and 10-year OS was 53% (95% CI: 41%-63%) and 42% (95% CI: 29%-54%), respectively (Fig.1). Relapses at 5 and 10 years were both 24% (95% CI: 16%-34%), while NRM at 5 and 10 years was 28% (95% CI: 19%-39%) and 37% (95% CI: 25%-50%), respectively. At day 100 after allo-HCT, the rates of acute GVHD grade II-IV were 41% (95% CI: 30%-51%) and grade III-IV of 16% (95%CI: 9%-25%). Chronic GVHD rates at 3 years were 62% (95% CI: 51%-72%), with extensive GVHD of 55% (95% CI: 44%-65%). On univariate analysis, age (> 60 or not), sex, TBI-based conditioning, donor type (MSD vs MUD), stem cell source or remission status prior to allo-HCT did not predict for overall survival in our study. Conclusions: Our results constitute the largest reported single-institution series with a long-term follow-up on allo-HCT outcomes in patients with aggressive T-cell NHL. The 5-year PFS and OS of 47 and 53%, respectively, are encouraging for the high-risk T-cell NHL patients with limited treatment options.

Abstract AITL is a rare peripheral T-cell lymphoma characterised by an aggressive behaviour, which primarily affects the elderly. Chemotherapy regimens fail to alter the high relapse rate and overall survival hardly exceeds 25% at 5 years. To date, there is no information on the potential role of allogeneic stem cell transplantation (allo-SCT) in the management of AITL. We report the outcome of 39 patients with a median age of 47 years (24–68), who underwent an allo-SCT between 1995 and 2004 for AITL, and were reported to the EBMT registry. The median time from diagnosis to transplant was 10 months (4–72). Thirty-four patients (87%) had previously received two or more treatment lines, and 16 patients (41%) a previous autologous SCT. Fifteen patients (38%) had a primary refractory disease, 13 (33%) were transplanted in partial remission and the remaining patients were in complete remission (CR) (mostly in 2nd and 3rd CR). Twenty-four patients were transplanted from an HLA-identical sibling and 15 from a matched unrelated donor. A myeloablative conditioning regimen (MAC) was used in 21 patients (cyclophosphamide + total body irradiation in 14), while 18 patients received fludarabine-based reduced intensity conditionings (RIC). Peripheral blood was the source of stem cells in 35 patients (90%). Three patients failed to engraft (one patient in the RIC group). Twenty-one patients (54%) developed acute graft versus host disease (grade I-II, n=16; grade III-IV, n=5). Twenty-eight patients (72%) achieved a CR after the allogeneic procedure. Nine patients died from transplant related mortality (TRM) and 5 patients from disease progression. The cumulative incidence of TRM at 12 months was 19% for the MAC and 26% for the RIC group. After a median follow-up for the surviving patients of 20 months (6–74), 25 patients are alive. Relapse rates at 1 and 3 years were estimated at 10% and 18% for the MAC and 16 and 20% for the RIC patients. Progression free survival rates at 3 years were 67% and 50% and the overall survival at the same time 71% and 56% for the MAC and RIC group of patients, respectively. Although follow up is rather short, these data suggest that allo-SCT results in good overall response and is associated with a low relapse rate in this group of poor risk heavily pre-treated and rather elderly group of AITL patients. Allo-SCT could be considered a therapeutic option for eligible high-risk AITL patients. Nevertheless, the impact of this approach should be further explored in prospective collaborative studies.

T Cell Lymphomas

Abstract Background: Peripheral T-Cell lymphomas (PTCLs) constitute approximately 10% of lymphoid malignancies and consist of several distinct entities based on pathologic and clinical characteristics. With the exception of a few subtypes (e.g., ALK-positive anaplastic large cell lymphoma (ALCL) and some primary cutaneous or leukemic forms of PTCL), a majority of PTCLs are aggressive as characterized by poor treatment response, rapid disease progression and poor overall survival. We have shown that landmark timepoints of event-free survival after diagnosis can stratify subsequent overall survival (OS) in diffuse large B-cell and follicular lymphoma. Here we evaluate this approach in newly diagnosed aggressive PTCLs treated with anthracyline-based or related chemotherapy. Methods. Newly diagnosed PTCL patients were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource (MER) from 2002-2012. Clinical data were abstracted from medical records using a standard protocol. For this analysis, we included patients receiving anthracycline-based or other multiagent chemotherapy for the following PTCL subtypes: ALK-negative ALCL (N=24); angioimmunoblastic T-cell lymphoma (AITL, N=34); PTCL, not otherwise specified (NOS; N=60); enteropathy-associated T-cell lymphoma (EATL, N=8); extranodal NK/T-cell lymphoma, nasal type (ENKTL, N=11); and hepatosplenic T-cell lymphoma (HSTCL, N=1). Patients were prospectively followed, and event-free survival (EFS) was defined as time from diagnosis to progression, re-treatment, or death due to any cause. Landmark EFS timepoints were assessed at 12 (EFS12) and 24 (EFS24) months after the date of diagnosis. Subsequent OS was defined as time from a specific endpoint (diagnosis, event or EFS landmark). Replication was performed in a population-based cohort of T-cell lymphomas diagnosed from 2000-2009 from the Swedish Lymphoma Registry. Results. 138 eligible patients were enrolled in the MER from 2002-2012, the median age at diagnosis was 58 years (range, 19-88), 66% were male, 73% had Stage III-IV disease, and 33% had IPI 0-1. At a median follow-up of 47 months (range 11-120), 87 patients (63%) had an event and 70 patients (51%) had died. From diagnosis, only 60 patients were event-free at 12 months (EFS12 45%). Patients who failed to achieve EFS12 had a poor subsequent OS from event (median OS = 6.8 months, 95% CI: 5.3-14.0, figure 1). In contrast, patients who achieved EFS12 had a favorable subsequent OS (median unreached, figure 2). Of the 427 eligible patients in the Swedish registry, the median age at diagnosis was 66 years (range, 18-88), 63% were male, 68% had Stage III-IV disease, and 25% had IPI 0-1. PTCL subtypes were: ALK-negative ALCL (N=89); AITL (N=80); PTCL, NOS (N=183); EATL (N=44); ENKTL (N=24); and HSTCL (N=7). At a median follow-up of 86 months (range 40-158), 333 patients (79%) had an event and 316 patients (74%) had died. From diagnosis, 183 patients were event-free at 12 months (EFS12 44%). Similar to the MER cohort, Swedish patients failing EFS12 had poor subsequent survival (median OS = 3.7 months, 95% CI: 2.9-5.3, figure 1). Swedish patients achieving EFS12 had a favorable subsequent OS (median OS = 89 months, figure 2). Similar results were obtained when conducting landmark analysis at 24 months after diagnosis (EFS24). Conclusion. Relapse and re-treatment events within the first 12 months of diagnosis are associated with very poor OS in PTCL treated with anthracyclines or related chemotherapy, while patients achieving EFS12 have encouraging subsequent OS. Stratifying patients into prognostically distinct subsets using EFS12 may help focus biologic and biomarker studies. EFS12 has potential as an early endpoint for studies of newly diagnosed PTCL. Further investigation of determinants related to post-EFS12 survival is needed. Disclosures Maurer: Kite Pharma: Research Funding. Cerhan:Kite Pharma: Research Funding.

Long Term Follow Up

Abstract Introduction Retrospective studies in MDS/sAML suggest that reducing the intensity of the conditioning regimen prior to allogeneic stem cell transplantation reduces the risk of non-relapse mortality but is associated with a higher risk of relapse. A higher risk of relapse after RIC was confirmed in a prospective BMT CTN study but the prospective randomized studies from the EBMT for MDS and sAML did not show a difference in outcome after 2 years (J Clin Oncol. 2017 Jul 1;35(19):2157-2164). Here we present a long term follow-up of the study after a median follow-up of 75 months (range 4-150 months). Methods Within the European Society of Blood and Marrow Transplantation (EBMT) we conducted a prospective, multicenter, open label, randomized phase III trial comparing comparing a busulfan based (Busulfan 8mg/kg orally or equivalent dosis intravenously (iv) plus fludarabin 180mg/m²) reduced intensity conditioning regimen (RIC) and a standard myeloablative busulfan (Busulfan 16mg/kg orally or equivalent dosis iv plus cyclophosphamide 120mg/kg) based regimen (MAC) in patients with MDS or sAML (<20 % blasts). Between May 2004 and December 2012, a total of 129 patients were enrolled from 18 centers. Patients were randomly assigned in a 1 : 1 ratio and stratified according to donor, age and blast count. Results In the first report (JCO 2017) the CI of NRM after 1 year was 17% (95% CI 8-26%) after RIC and 25% (95% CI 15-36%) after MAC (p = 0.29). The CI of relapse at 2 years was 17% (95% CI 8-26%) after RIC and 15% (95% CI 6-24%) after MAC (p = 0.6), resulting in a 2 year relapse-free and overall survival of 62% (95% CI 50-74%) and 76% (95% CI 66-87%) after RIC and 58% (95% CI 46-71%) and 63% (95% CI 51-75%) after MAC (p = 0.58 and p = 0.08, respectively). In the current follow-up study, all cases but one who were alive at last report could be updated. The median follow-up is now 75 months in the MAC and 72 months in the RIC arm. Since last follow-up =18 death occurred in both arm (MAC n=8, RIC n=10) 8 relapses (MAC n=4; RIC n=4) and 6 NRM (MAC n=2; RIC n=4). Second allogeneic stem cell transplantation was performed in 18 patients (n=10 in RIC and n=8 in MAC) due to graft failure (n=4) relapse (n=11) and others (n=3). The CI of chronic GvHD at 5 years was 65% (95% CI: 53-78) after RIC and 68% after MAC ((95% CI: 55-81; p = 0.70). At 5 years there was no difference in CI of NRM (22%, 95%CI: 12-32 vs 30% , 95%CI : 19-42, p=0.5) in CI of Relapse (22% , 95% CI: 12-32 vs18%, 95% CI: 8-28, p= 0.7), Relapse free- (57%, 95% CI: 44-69 vs51%, 95% CI: 39-64, p=0.8) and Overall survival (69%, 95% CI: 58-80 vs 53%, 95% CI: 40-65, p=0.15) between RIC and MAC, respectively. Conclusion This long term follow-up of the prospective randomized EBMT trial confirmed early results that RIC resulted in at least similar long term relapse-free and overall survival as MAC in patients with MDS or sAML.

Dismal Prognosis

Abstract Patients with aggressive forms of Mycosis Fungoides (MF), Sézary syndrome (SS) and other less common subtypes of primary CTCL have a dismal prognosis with conventional therapy. A potential role for alloSCT in these patients has been suggested by a number of case-reports and small series. We conducted a retrospective registry analysis of 64 recipients who received an alloSCT from HLA-identical donors (52 related, 12 unrelated) for advanced CTCL reported to EBMT between 1997 and 2006: 23 MF, 21 SS, 16 primary cutaneous anaplastic large cell lymphoma and 4 subcutaneous panniculitis-like T-cell lymphoma; 38 patients were male, 26 were female; median age was 46 years (5–65); median follow up of survivors was 28 months. AlloSCT was performed at a median of 22 (3–313) months from initial diagnosis, following a median of 3 (1–8) prior lines of therapy, the stem cell source was PB in 54 cases and BM in 10 cases, reduced-intensity conditioning (RIC) was used in 41 (64%) cases. Twenty-three percent of patients were in complete response (CR) and 26% in partial response (PR) at the time of alloSCT. All other patients were primary refractory (RE, 25%) or progressed after a previous response (PG, 26%). Non-relapse mortality was 24% at 3 years, and appeared higher in patients receiving myeloablative conditioning (MAC) than in those receiving RIC alloSCT (35% vs 16%; p=0.06). Acute graft versus host disease (GVHD) occurred in 37% of patients at risk, and chronic GVHD in 69% of patients alive at day +100. The cumulative incidence of disease relapse (36% at 3 years) was significantly higher in patients with advanced disease status at alloSCT (RE/PG 46% vs CR/PR 21%; p=0.01), but similar in patients with related and unrelated donors (p=0.39) and receiving MAC or RIC (p=0.6). Progression free survival (PFS) at 3 years was 41%, with a significant advantage for patients in CR/PR at alloSCT (58% vs 26%; p<0.01), but not for type of conditioning (MAC 45% vs RIC 44%; p=0.4) or donor type (related 46% vs unrelated 33%; p=0.2). Out of 22 patients who relapsed, 10 remain alive and 4 of these were in CR at last follow up, possibly indicating that a proportion of patients achieved a better control of CTCL following relapse after alloSCT. Overall survival for the whole series was 55% at 3 years, with a trend towards an improved OS for patients with disease in CR/PR at transplant (65% vs 46%; p=0.1). Overall, outcome after allogeneic transplantation appears superior to that expected for such patients under conventional therapy. Our analysis reinforces the important role of alloSCT in advanced stage CTCL in a relatively large registry-based series.
