Abstract BACKGROUND Embryonal tumours with multilayered rosettes (ETMR) are highly aggressive tumors, mostly occurring in infants. Published clinical data refer to retrospective cohorts of inhomogeneously treated patients. Here, we describe the outcome of patients, who were prospectively treated within the P-HIT2000-trial, the subsequent HIT2000-interim-registry and earlier HIT-trials. PATIENTS AND METHODS Nineteen patients from the P-HIT2000-trial (2001–2011), 12 patients from the subsequent HIT2000-interim-registry (2012–2014) and 4 patients from earlier HIT-trials with centrally reviewed neuropathological and molecularly-confirmed diagnosis of ETMR were included. Outcome of 18 patients treated with carboplatin-etoposide-induction followed by tandem-high-dose chemotherapy (“CARBO-ETO+HDCT”) with stage-stratified radiotherapy administered in case of persistant disease, relapse or progression were compared to patients treated with HIT-SKK chemotherapy ± radiotherapy (n=9) or other regimens (n=8). RESULTS Median age at diagnosis was 2.9(1.0–5.3) years. Metastases at diagnosis were detected in 9 patients (26%). For the entire cohort of n=35, 5-year overall survival (OS) was 26.7%, and progression-free survival (PFS) was 18.5%. Five-year OS for patients with CARBO-ETO+HDCT, SKK chemotherapy or other regimens was 44.4%, 13.0% and 0%, respectively (p=0.006). Five-year PFS was 33.3%, 0% and 0%, respectively (p=0.119). Of 10 survivors, n=8 were treated with CARBO-ETO+HDCT; n=4 had craniospinal, n=2 local and n=4 no radiotherapy. Impact of initial gross-total-resection (p=0.231) and non-metastatic disease (p=0.097) was limited. CONCLUSIONS We show improved survival with carboplatin-etoposide-induction followed by tandem-high-dose chemotherapy, indicating that a cure is possible for some patients. However, despite intensive treatment, outcome is unsatisfactory and innovative therapies urgently need to be included in an upfront setting.

PURPOSE A phase I/II study was performed to evaluate the incorporation of hydroxyurea (HU) into high-dose chemotherapy of non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Thirty-eight patients with primary refractory and refractory relapsed NHL were treated with carmustine (BCNU) (300 mg/m2 on day -8), cyclophosphamide (Cy) (2.5 g/m2/d on days -8 and -7), etoposide (E) (150 mg/m2 every 12 hours on days -6, -5, and -4), and HU (BCHE) with autologous hematopoietic stem-cell rescue. Twenty-one patients received HU in a dose escalation of 2 to 12 g/m2 intravenously (IV) by 72-hour continuous infusion. When the IV formulation was not available, 17 patients were given 18 g/m2 of HU orally in divided doses every 6 hours over the same 72-hour period. RESULTS The dose-limiting toxicity of 72-hour continuous infusion HU in this regimen was mucositis. Endotracheal intubation was necessary to protect the airway in two thirds of patients treated at 12 g/m2. Six patients (oral BCHE, five of 17; IV BCHE, one of 21) died with nonresponding or progressive disease and, at least in part, from the complications of the high-dose chemotherapy. Seventeen patients (45%) achieved complete remission (CR). More patients treated with IV BCHE achieved CR than patients treated with oral BCHE (12 of 21 v five of 17; P < .1, chi 2 test). Nine patients (two of 17 oral BCHE and seven of 21 IV BCHE) remain disease-free as of January 31, 1994, with a minimum follow-up time of 3 years. The lower mortality and higher response rate with IV BCHE translated into a significantly superior probability of progression-free survival (PFS) (33% at 4 year v 12% for oral BCHE; P = .048, log-rank test). CONCLUSION High-dose BCHE is effective treatment for primary refractory and refractory relapsed NHL. Continuous IV HU appears to be less toxic and more effective than intermittent oral HU in this regimen.

Abstract Background Diffuse large B-cell lymphoma (DLBCL) accounts for 30% to 40% of non-Hodgkin’s lymphoma (NHL) cases in Western countries. Although two-thirds of patients may be cured with combination chemotherapy, in the event of treatment failure and for those who are refractory to treatment, survival is usually measured in months. Several therapeutic modalities have been utilized for patients with relapsed or refractory disease, but among patients who are not eligible for high-dose chemotherapy with stem cell transplant, a comprehensive assessment of efficacy and safety is lacking. This systematic literature review (SLR) was designed to exhaustively collect and review information on the clinical efficacy and safety of the different interventions used in the treatment of refractory or relapsed DLBCL, and if possible to perform a meta-analysis. Methods Electronic databases (PubMed, Cochrane Library, Embase) were searched for relevant studies published from 1997 to August 2, 2012. In addition, conference abstracts, bibliographic reference lists of included articles and recent reviews, and the Clinicaltrials.gov database were searched for phase 2, 3, or 4 studies displaying results, potentially unpublished in peer-reviewed journals. Main efficacy outcomes included objective response rate (ORR), complete response, partial response, duration of response, progression-free survival (PFS), and overall survival (OS). Safety endpoints focused on grade 3/4 toxicities and treatment discontinuation due to toxicity. Studies had to report on relapsed or refractory DLBCL after at least one standard treatment and patients who were not eligible to receive high-dose chemotherapy or stem cell transplant (autologous or allogeneic). Mixed type NHL studies were required to report DLBCL outcomes separately for inclusion. Results A total of 3,308 publications were identified in the first pass of a broad SLR on NHL; of these, 57 provided relevant data for DLBCL representing 54 unique studies. Of the 54 studies, there was 1 phase 3 study, 33 phase 2 studies, and 4 phase 1/2 studies (15 studies did not report the study phase and 1 was an observational study). Six studies were comparative (3 randomized trials; 3 nonrandomized trials) with two treatment arms; 48 studies were single arm. Of the 48 regimens evaluated, few regimens were represented more than once. Overall survival and PFS were often not reported or not reported separately for the patients with DLBCL in studies that enrolled patients with any of the multiple lymphoma histologies. Refractory and relapsed criteria were often not defined, and definitions were heterogeneous when available. The ORR from the few comparative studies ranged from 27% to 100%, with most estimates between 40% and 70%. PFS with low and high doses of obintuzumab was 2 months and 3 months, respectively in one study, and OS was 4 months with MEP and 7 months with C-MEP in another study. There was a common regimen in two of the randomized controlled trials, but the patient populations in these studies differed too greatly to allow a valid meta-analysis to be performed. In the single-arm studies, ORR ranged from 11% to 100%, with the estimates evenly distributed across that range. Progression-free survival was approximately 1 to 10 months. Reported median OS ranged from 1 to 13 months. Main safety concerns included thrombocytopenia, leukopenia, and neutropenia. Conclusions There is a high unmet need for effective therapies for patients with relapsed or refractory DLBCL who are ineligible for stem cell transplant. Although numerous regimens have been evaluated in single-arm trials and a handful in comparative studies, there is no clearly superior regimen for patients with relapsed or refractory DLBCL, especially in third- and later lines of therapy.

522 Background: HDCT plus PBSCT is effective salvage therapy for relapsed mGCT but has potential toxicity which can be more pronounced in older patients. We report survival and toxicity outcomes in pts with relapsed mGCT age ≥ 40 at time of HDCT. Methods: 440 consecutive pts with relapsed mGCT were treated with HDCT and PBSCT with tandem cycles at Indiana University (IU) between 2004-2017 per our previous reported regimen (N Engl J Med 2007; 357: 340-8). Kaplan-Meier methods were used for progression free survival (PFS) analysis. Results: 110 pts were age ≥ 40 while 330 pts were age < 40. Among pts age ≥ 40, median AFP was 6.6 (range, 1-2,709) and median hCG was 5.3 (range, 1-42, 453). Of the 110 pts age ≥ 40, 75 had complete remission without relapse during a median follow-up of 23 months. There were 3 treatment-related deaths. Conclusions: HDCT plus PBSCT is safe and effective salvage therapy in pts age ≥ 40 with relapsed mGCT. [Table: see text]

Abstract Background: For a long time, multiple myeloma has been a disease with a poor outcome. High dose (melphalan) chemotherapy followed by autologous stem cell transplantation has been reported to improve the overall and progression-free survival of these patients. Objective: To determine the survival of multiple myeloma patients treated with conventional chemotherapy and compare it with that of patients treated with high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation. Design/Methods: 83 myeloma patients treated at a single institution were included in this retrospective study. They were divided into two groups: one group of patients who were received high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (n=42) and one group of patients who only received conventional chemotherapy and were eventually also treated with thalidomide and/or corticosteroids (n=41). The distribution of the stages of the disease according to Salmon and Durie were similar in both groups of patients. For both groups, the overall and progression-free survival was calculated. Results: In the general analysis, myeloma patients who underwent an autologous transplant had a significantly longer overall survival (58.8 vs. 52.2 months, p=0.036) and progression-free survival (39.6 vs. 11.8 months, p &lt; 0.001) in comparison with the conventional chemotherapy group. If analysis was restricted to those patients who were transplanted as a first-line treatment, there was no significant difference in overall survival in comparison with conventional chemotherapy (51.8 vs. 52.2 months, p= 0.422); progression-free survival was significantly better in the first-line transplant arm as compared to the conventional chemotherapy arm (35.4 vs. 11.8 months, p= 0.003). As the median age in the transplant arm was significantly lower than in the conventional chemotherapy arm, we also performed a sub-analysis of patients who were between 60 and 70 years of age at diagnosis; there was no significant difference in overall survival between the two groups (60.7 vs. 69.5 months, p= 0.656), while the progression-free survival was again better in the autologous transplant group as compared to the conventional chemotherapy group (41.0 vs. 8.4 months, p= 0.020). Conclusion: High-dose chemotherapy and autologous stem cell transplantation in the treatment of myeloma is associated with improved progression-free survival and in the general analysis, with improved overall survival. The overall survival of patients who were only treated with conventional chemotherapy is somewhat higher (more than 4 years) as compared to that of historical controls (2–3 years).

Abstract Abstract 903 Background: High-dose chemotherapy (HDC) with autologous stem cell transplant (ASCT) is a standard component of therapy for some patients with hematologic malignancies, particularly those with relapsed or refractory lymphoma. No high-dose chemotherapy regimen has been shown to be superior to another, and thus regimens are chosen based on institutional standards and toxicity profiles. Pneumonitis is a recognized complication of HDC regimens containing BCNU. There has not been a large study of uniformly-treated lymphoma patients to define the incidence and risk factors for developing pneumonitis in the modern era. Methods: We retrospectively examined the medical records of patients who were treated with HDC-ASCT at the Dana-Farber Cancer Institute and Massachusetts General Hospital Cancer Center from 2007–2009 using a regimen containing cyclophosphamide 750 mg/m2 Q12h x4d, BCNU 112.5 mg/m2 daily x4d, and VP-16 (etoposide) 200 mg/m2 Q12h x4d (CBV). Overall (OS) and progression-free survival (PFS), and the incidence of pneumonitis were determined. Univariable and multivariable analyses were performed for characteristics likely to be associated with an increased risk of pneumonitis, which was defined based on a combination of clinical, laboratory, and radiographic factors, with or without bronchoscopy. Results: 222 patients were analyzed. The age range was 21–77 (median 54). 61% were male. 71% had non-Hodgkin lymphoma and 29% had Hodgkin lymphoma. The median number of prior chemotherapy regimens was 2; 65% of patients had received prior rituximab, 31% prior bleomycin, and 12% prior gemcitabine. 71% had disease involvement of the mediastinum, and 11% had received prior mediastinal radiation therapy. 43% were past or present smokers. The median follow-up among all living patients was 12 months. The total cumulative incidence of pneumonitis was 22% (49 patients), with 41 patients (19%) receiving corticosteroid treatment, and 18 patients (8%) requiring inpatient hospitalization for pneumonitis. The time range to development of pneumonitis was 26–199 days post-transplant, with a median of 50 days. There were four treatment-related deaths (1.8%): three related to pneumonitis and one related to veno-occlusive disease. On univariable analysis, age, diagnosis of Hodgkin lymphoma, prior mediastinal radiation, prior bleomycin, total BCNU dose delivered, and lack of complete remission status at the time of ASCT were associated with the development of pneumonitis. Gender, body mass index, history of smoking, mediastinal disease involvement, prior rituximab, prior gemcitabine, and pretransplant pulmonary function testing were not found to be statistically significantly different between patients with and without pneumonitis. Stepwise multivariable logistic regression analysis, excluding 31 patients without pneumonitis who had death, relapse, or censoring in the first four months post-transplant, revealed the following variables as independently associated with development of pneumonitis: prior mediastinal radiation (odds ratio 6.5, 95% CI 2.2–18.9, P=0.0005), total BCNU dose above 1000 mg (OR 3.4, 95% CI 1.3–8.7, P=0.012), and age less than 54 (OR 3.0, 95% CI 1.4–6.5, P=0.0037). One year overall survival was 92%, and progression-free survival was 71%. There were no variables, including pneumonitis, associated with PFS on multivariable analysis. Only lack of complete or partial disease response prior to ASCT was associated with inferior OS on multivariable Cox regression modeling (hazard ratio 0.2, 95% CI 0.05–0.72, P=0.01). Conclusions: Pneumonitis is relatively common after HDC-ASCT using CBV conditioning. Increased vigilance for symptoms of pneumonitis is warranted for patients with prior mediastinal radiation and for younger patients. Our data suggests an increased risk with total BCNU dose above 1000 mg, suggesting a possible threshold toxicity effect. Empiric dose reduction may be considered for patients who would receive greater than 1000 mg of BCNU, particularly if they are also younger and/or have had prior mediastinal radiation. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 2743 Background: Based on the impressive results of two pivotal phase II trials, the CD30 targeting antibody-drug conjugate brentuximab vedotin (SGN-35) was approved for the treatment of relapsed Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) by the Food and Drug Administration (FDA) in 2011. Recently, we reported the experience of the German Hodgkin Study Group (GHSG) with brentuximab vedotin as single agent in 45 patients suffering from refractory or relapsed CD30-positive HL. In this cohort with a median age of 35 years and a median number of four prior chemotherapy regimens, overall survival (OS) and progression-free survival (PFS) at 12 months were 83% (95%-CI: 72%-95%) and 43% (95%-CI: 28%-58%), respectively. Interestingly, 10 of 17 patients considered very high-risk (59%) who had primary refractory disease or early relapse and refractory disease prior to brentuximab vedotin treatment, achieved an objective response, which was comparable to the overall response rate of 60% for the whole cohort (Rothe et. al., Blood, July 2012). Since very limited data is available on relapsed or refractory HL patients who received brentuximab vedotin without prior high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT), we have expanded our analysis. Methods: Since March 2010, the GHSG and associated centres have treated patients with refractory or relapsed HL or relapsed ALCL with brentuximab vedotin. In addition to six patients included in our previous analysis, we identified 10 further patients who had not undergone prior HDCT and SCT and were treated with brentuximab vedotin. All patients had histologically confirmed CD30-positive lymphoma and were treated within a named patient program (NPP). All participants gave written informed consent in accordance with the Declaration of Helsinki. Patients received a 30-minute infusion of brentuximab vedotin dosed at 1.8mg/kg body weight every three weeks. Response was defined according to the revised response criteria for malignant lymphoma. Overall survival (OS) was defined as the time from the initiation of therapy to death from any cause. Progression-free survival (PFS) was measured from initiation of therapy to progression, relapse, or death from any cause. Results: In total, 16 patients with HL (n=14) or ALCL (n=2) with a median age of 48.5 years and a median number of three prior chemotherapy regimens were analyzed. Reasons for ineligibility for HDCT and autologous SCT prior to treatment with brentuximab vedotin were refractory disease (n=11), comorbidity (n=4) and unknown reasons (n=1). Treatment with brentuximab vedotin resulted in an objective response in 11 patients (69%), including five complete remissions. Noteworthy, six of the 11 patients with chemotherapy refractory disease and all four patients with significant comorbidity achieved an response. Six patients received a consolidating HDCT followed by autologous (n=4) or allogeneic (n=2) SCT after brentuximab vedotin treatment. OS and PFS at 12 months were 68% (95%-CI: 40%-95%) and 22% (95%-CI: 0%-48%), respectively. Conclusion: This retrospective analysis supports the previously reported excellent therapeutic efficacy of brentuximab vedotin in patients with heavily pre-treated CD30-positive malignancies. Moreover, we present the first data indicating therapeutic efficacy of brentuximab vedotin as reinduction therapy in chemotherapy-refractory HL and ALCL patients before HDCT and ASCT.

Abstract Many new therapeutic agents have been approved for follicular lymphoma (FL) but none appear to be curative. Despite novel agents, some patients (pts) experience early relapse, become chemorefractory or suffer transformation into more aggressive lymphomas. Options for these pts are limited. High dose chemotherapy with autologous stem transplant (ASCT) prolongs progression free survival (PFS) and overall survival (OS) in FL pts in first relapse and registry data shows favorable outcome with ASCT in cases of histologic transformation. However, ASCT is usually not curative. Myeloablative allogeneic transplant (MT) has produced long term PFS but is hampered by significant non relapse mortality (NRM) while nonmyeloablative transplant (NMT) has a higher relapse rate compared to MT especially in high risk pts. Finally, many transplant studies have excluded these high risk pts such as those with chemorefractory or transformed disease. We hypothesized that a tandem transplant consisting of an ASCT followed by a NMT would confer the same benefit as a MT without the associated high NRM by separating the high dose chemotherapy from graft versus host disease (GVHD) while preserving the graft versus lymphoma effect. The goal of our study was to improve long term PFS in high risk FL pts. We therefore initiated a prospective protocol in April 2003, for pts with high risk relapsed FL as defined by chemorefractory disease, early 1st relapse, >1st relapse or transformation into aggressive histology. At least one therapy was attempted to document chemosensitivity prior to ASCT. However, regardless of disease status prior to transplant, pts underwent ASCT followed 3 months later by an outpatient NMT from an HLA-identical sibling. NMT comprised 5 days of fludarabine 30 mg/m2/day and cyclophosphamide 300mg/m2/day followed by an infusion of >2x106CD34+ cells/kg. GVHD prophylaxis, chosen to take advantage of the low incidence of acute (a) GVHD and the putative protective effect of chronic (c) GVHD, consisted of tacrolimus starting on day (D) - 8 to achieve levels of 8-12 nmol/L then tapered off by D+100 or D+180 depending on disease risk and of mycophenolate mofetil 1g bid from D+2 to D+50. We previously reported on 27 pts with a follow-up (f/u) of 3 years (yrs). We now report a larger cohort of 40 pts with a median f/u of 8 yrs. Up until July 2015, 40 pts were enrolled with a median age of 50 yrs (34-65). Pts had previously been treated with a median of 3 lines of therapy (2-6). Median time from diagnosis to ASCT was 33 months. Disease status at ASCT was: 14 CR, 16 PR and 10 refractory. Conditioning for ASCT included BEAM/BEAC (n=39), and Cy-TBI (n=1). In addition, 4 pts received radiotherapy after ASCT to sites of previously bulky disease. Median time between ASCT and NMT was 138 days (75-238). Pre NMT disease status was: 25 CR, 12 PR and 3 refractory. Engraftment was prompt in all pts after ASCT and median neutrophil and platelet recovery were respectively 13 days (0-19) and 0 day (0-18) post NMT. Seven pts (18%) developed aGVHD: 2 grade II and 5 grade III. Overall, 29 pts (73%) developed cGVHD: 1 mild, 13 moderate and 15 severe according to NIH revised criteria. Median time to discontinuation of immunosuppression was 22 months. To date, 2 pts have progressed at 11 and 59 months post NMT (one died from relapse and one is now in CR after chemotherapy and DLI) and 5 pts died from either GVHD related complications (n=4) or unknown cause (n=1). All pts alive at last f/u were in CR. With a median f/u of 8 yrs in surviving pts (1-12), OS is 95% at 3 and 5 yrs and 82% at 8 yrs. PFS is 92% at 3yrs, 89% at 5 yrs and 80% at 8 yrs. NRM and relapse rate at 8 yrs are 18% and 6% respectively. Based on our current results in 40 pts, we conclude that ASCT followed by sibling NMT for high risk relapsed FL is associated with excellent disease response and PFS. Furthermore, this tandem strategy appears to be safe and well tolerated. The incidence of cGVHD remains high but could in part explain the impressive PFS in this high risk cohort. This approach should now be further explored in a multi institution setting, include matched unrelated donors and consider the addition of rituximab post-transplant to reduce the incidence and severity of cGVHD with the hope that relapse will not be increased.

Abstract Introduction: For patients with relapsed or refractory diffuse large B cell lymphoma (DLBCL), salvage treatment followed by consolidation with high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT) is the standard of care for those with chemosensitive disease, as established by the PARMA and CORAL trials. In the pre-rituximab era, patients with DLBCL experiencing disease progression following HD-ASCT had a dismal prognosis with a median overall survival of 3 months. These early studies demonstrate that early progression following HD-ASCT is the most important predictor of poor outcome. In the rituximab era, there is very little data examining incidence and outcomes of patients with late relapses following HD-ASCT for relapsed/refractory DLCBCL. Therefore, we sought to evaluate survival outcomes in a cohort population of patients relapsing late after HD-ASCT for DLBCL. Methods: We reviewed consecutive patients who underwent HD-ASCT for biopsy confirmed relapsed or refractory DLBCL between 2001 and 2010 at the University of Rochester James P. Wilmot Cancer Institute. Eligible patients were required to have received rituximab as part of their therapeutic regimen. Survival probability was estimated by the Kaplan-Meier method. Comparisons were made using the X2 test and Fisher's exact test, where appropriate. Results: A total of 88 patients were identified. Median age was 55 (range 20-74). Eighty percent of patients received a BEAM – like conditioning regimen (Carmustine, Etoposide, Cytarabine, and Melphalan). Thirty-five patients were in complete remission at the time of transplant. Median follow up for surviving patient was 5.8 years (range 139 days -12.5 years). The median overall survival for all patients was 5.2 years (range of 15 days-12.5 years). In total, 51 patients died (58%); 31 of these deaths were related to DLBCL (61%). Median progression free survival was not reached. Thirty-five patients relapsed following ASCT. Of these, 89% relapsed < 3 years from ASCT (early relapse), 2 of whom remain alive. Only 4 patients (11%) relapsed ≥ 3 years from ASCT (late relapse), 2 of whom died, and 2 of whom remain alive. Of the deaths, 1 was lymphoma-related, and 1 was death from graft versus host disease in a patient undergoing subsequent allogeneic transplant. Median time to progression in the entire cohort was 167 days. Consistent with early studies, the presence of disease status prior to ASCT was associated with shorter time to progression, p=0.0028 by Fisher's exact test. Conclusions: Ours is one of few series examining late relapses following ASCT performed for relapsed and refractory DLBCL in the rituximab era. In this cohort, late relapses following ASCT for relapsed and refractory DLBCL occurred infrequently. Our data indicate that for the few patients relapsing beyond 3 years, there is a suggestion of long-term disease control. Figure 1: Figure 1:.

Abstract Purpose To investigate safety and efficacy of high-dose chemotherapy followed by autologous stem cell transplantation (HCT-ASCT) in patients with relapsed or refractory primary CNS lymphoma (PCNSL). Patients and methods We conducted a single-arm multicentre phase 2 study for immunocompetent patients (<66 years of age) with PCNSL failing prior HD-MTX based chemotherapy. Induction treatment consisted of 2 courses of rituximab (rituximab 375mg/m2), high-dose cytarabine (2 x 3g/m2) and thiotepa (40mg/m2) with collection of autologous stem cells in between. Conditioning treatment for HCT-ASCT consisted of rituximab 375mg/m2, carmustine 400mg/m2 and thiotepa (4 x 5mg/kg). Patients commenced HCT-ASCT irrespective of response status after induction. Only patients not achieving complete remission (CR) after HCT-ASCT received whole brain radiotherapy (WBRT). The primary endpoint was CR after HCT-ASCT by intention-to-treat (ITT). Secondary endpoints included safety, progression free survival (PFS, time to progression or death) and overall survival (OS, time to death due to any cause). Results Between May 2007 and July 2012, we enrolled 39 patients from 12 German centres. The median age and Karnofsky performance score was 57 years (range 37 to 65) and 90% (range 60% to 100%), respectively. 28 (71.8%) patients had relapsed and 8 (28.2%) refractory disease. 22 (56.4%) patients responded to induction (4 CR, 18 partial remissions [PR]) and 32 (82.1%) patients commenced HCT-ASCT. 22 patients (56.4%, 95% CI 39.6% to 72.2%) achieved CR after HCT-ASCT, 6 (15.4%) achieved PR, and 1 (2.6%) had stable disease. In 9 (17.8%) patients the final scan was not done, because 7 (18.0%) did not undergo HCT-ASCT and 2 died (5.1%) during HCT-ASCT procedure. After a median follow-up of 45.2 months, the respective 2-year PFS and OS rates were 46.0% (95% CI 30.3% to 61.7%, median PFS 12.4 months, Figure 1) and 56.4% (95% CI 40.8% to 72.0%); median OS not reached (Figure 2). The non-relapse mortality rate was 10.3% (95% CI 4.1% to 26.0%) at 1 year without any further increase afterwards. In the subset of 32 patients who received HCT-ASCT, 14 (56.3%) experienced progression or died translating into 1 and 2-year PFS rates (calculated from date of HCT-ASCT) of 62.5% (95% CI 45.7% to 79.3%) and 56.1% (95% CI 38.8% to 73.3%) with no further decrease afterwards. Main grade 3 or higher toxicities were hematological as expected. We recorded four (10.3%) treatment-related deaths, 2 during induction and 2 during HCT-ASCT. Conclusions In eligible PCNSL patients failing HD-MTX based chemotherapy, a short induction with high-dose cytarabine and thiotepa followed by HCT-ASCT is an effective treatment option. Our data provide a reliable benchmark for future comparative studies needed to further scrutinize the role of HCT-ASCT in the salvage setting for PCNSL. Figure 1. Progression free survival Figure 1.
