Abstract Background Ibrutinib (Ibr), an oral, first-in-class covalent Bruton's tyrosine kinase inhibitor, showed in the Phase 3 RESONATE trial significantly improved progression-free survival (PFS, hazard ratio [HR] =0.22, p<0.001) and overall survival (OS, HR=0.39,p=0.001) compared with ofatumumab (ofa) in patients with previously treated CLL who were not eligible for chemoimmunotherapy (Byrd et al, NEJM 2013). Long-term follow-up data from a single arm Phase 2 study have also demonstrated that patients treated with ibrutinib have long durable responses with a PFS at 2.5 years of 69% (Byrd et al, Blood 2015). While ofatumumab is a licensed comparator and included in treatment guidelines, some Health Technology Assessment (HTA) bodies require comparisons with a wider range of treatments. In the absence of direct head-to-head comparison of single-agent ibrutinib with other frequently used treatments in this patient population, additional comparative evidence against standard of care as observed in clinical practice can provide useful insights on the relative efficacy of ibrutinib. Naïve (unadjusted) comparisons of outcomes from different sources are prone to bias due to confounding, as treatment assignments were not randomly assigned, and populations can vary in important prognostic factors. The objective of this analysis was to compare the relative efficacy of Ibr versus physician's choice in R/R CLL-patients based on patient-level data from RESONATE pooled with an observational cohort, adjusting for confounders using multivariate statistical modelling. Methods Patient-level data from the Phase 3 RESONATE trial (Ibr: n=195; ofa: n=196) were pooled with data from a retrospective observational study conducted in the Stockholm area in Sweden. This retrospective study collected efficacy and safety data from a detailed, in-depth retrospective review of individual patient files from 148 consecutively identified patients with R/R CLL initiated on second or later line treatment between 2002 and 2013 at the four CLL-treating centers in Stockholm, Sweden, with complete follow-up. Longitudinal follow-up in subsequent treatment lines was available for patients in 3rd (n=91), 4th (n=51), 5th (n=29), and 6+ (n=15) line, and as such individual patients could contribute information to the analysis for multiple lines of therapy, with baseline defined as the date of initiation of the actual treatment line. A multivariate cox proportional hazards model was developed to compare PFS and OS between treatments, including line of therapy, age, gender, Binet stage, ECOG, and refractory disease as covariates. Adjusted HRs and 95% CIs are presented vs. Ibr. Results Across all treatment lines, fludarabine-cyclophosphamide (FC) (n=64), chlorambucil (n=59), alemtuzumab (n=33), FC+rituximab (FCR) (n=30), bendamustine+rituximab (BR) (n=28), and other rituximab-based combination chemotherapy (n=28) were the most frequently used treatments. Line of therapy, age and gender, Binet stage, ECOG performance status, and refractory disease were all independent risk factors for worse outcome on both PFS and OS. The adjusted HR for PFS and OS pooled observational data versus Ibr were 6.80 [4.72;9.80] (p<0.0001) and 2.90 [1.80;4.69] (p<0.0001). HR's for PFS/OS versus most frequent treatment regimens ranged between 2.50/1.82 (FCR) and 14.00/5.34 (anti-CD20 Mab). Baseline adjusted results for the Ofa-arm in RESONATE were comparable for both PFS and OS to outcome data from the consecutive historical cohort, however OS outcomes for Ofa were partly confounded by cross-over to Ibr. Conclusions Comparison of results from the Phase 3 RESONATE study with treatments used as part of previous standard of care in a well-defined cohort of consecutive Swedish patients shows that ibrutinib is superior to physician's choice in patients with relapsed/refractory CLL, suggesting a more than 6 fold improvement in PFS and almost 3 fold improvement in OS. Results were consistent across all different physician chosen treatments and provides further evidence that ibrutinib improves both PFS and OS vs current and prior standard of care regimens.

Abstract BACKGROUND The role of autologous stem cell transplantation (ASCT) in Waldenström Macroglobulinaemia (WM) is not well established, largely due to the paucity of evidence. It remains unclear where ASCT should be placed in the sequence of treatment lines. The debate is stronger in the era of targeted therapies that can achieve prolonged progression free survival (PFS) intervals and expected treatment-free intervals of approximately 4 to 8 years. The goal of this real world analysis was to review response and survival outcomes, and relapse risk factors in WM patients who underwent ASCT in a single WM referral centre. METHODS A retrospective cohort analysis was undertaken of consecutive WM patients treated with ASCT at a single specialist centre between 2003 and 2020. Baseline demographic/biological data, number/types of prior therapies, and pre- and post-ASCT depth of response, were collected from patient records and the WMUK Rory Morrison Registry. The primary aims were to determine depth of response, overall survival (OS), progression free survival (PFS), transplant related mortality (TRM) and relapse-associated mortality. RESULTS A total of 32 patients received ASCT, with a median age at time of ASCT of 57 years (range 40-68 years) and median interval from diagnosis to ASCT of 2.3 years (range 0.5-16.8 years); 14 (43.7%) were male. Prior to ASCT, 11 patients (34%) had received one therapy, 11 patients had 2 lines of treatment (excluding mobilisation), and 10 patients (31%) had received 3 or more therapies. The disease status pre-ASCT was complete remission (CR)/very good partial response (VGPR) in 14 patients (43.7%) and partial response (PR) in 18 patients (56.2%). Conditioning therapy comprised LEAM (Lomustine, Etoposide, Cytarabine, Melphalan; 18 patients, 56.2%), BEAM (Carmustine substituted for Lomustine; 12 patients, 37.5%), or Melphalan only (2, 6.2%). All patients had successful engraftment. Median time from stem cell reinfusion to hospital discharge was 15.5 days (range 13-187 days) in the 24 patients for whom these data were available; 5/24 patients (21%) were discharged &gt;25 days after stem cell reinfusion. Restaging at 100 days post-ASCT showed deepening of response by ASCT in 17 patients (53.1%). CR/VGPR was achieved by 26 patients (81.2%) and PR by 4 patients (12.5%). Two patients (6.2%) experienced disease progression before day 100 post-ASCT (both receiving ASCT in second remission/PR2). At a median follow up of 8.9 years (range 0.1-18 years), the estimated median PFS was 4.5 years (95% confidence interval [CI] 3.2-5.7 years), with estimated 2-year and 5-year PFS rates of 75% and 35.9%, respectively (Figure 1A). In this small cohort, there was no significant difference in PFS based on age, number of prior lines of treatment, pre-ASCT remission status (CR/VGPR vs PR) or post-ASCT response achieved. At time of analysis, 14/32 patients (43.7%) had died: TRM rate was 6.2% (2 patients died during inpatient admission of ASCT complications), 4 patients (12.5%) died of PD, and 1 patient died of unknown causes. Another 7 patients (21.9%) died of infective causes after the immediate post-ASCT period: the median time from ASCT to death among these patients was 5.5 years (range 0.8-10.8 years). Estimated median OS for the unstratified cohort was 10.8 years (95% CI 7.3-14.3 years), with estimated 2- and 5-year OS rates of 87.5% and 77.5%, respectively (Figure 1B). Overall survival did not differ significantly based on age at time of ASCT, number of therapy lines prior to ASCT, pre-ASCT remission status (CR/VGPR vs PR) or post-ASCT response achieved. One patient (3.1%) underwent ASCT after BTK inhibitor therapy, achieving deepening of response (PR to VGPR) with ASCT and progression free interval of 11 months. CONCLUSION ASCT is a feasible treatment option for patients with relapsed WM, producing deeper responses following salvage therapy and resulting in PFS intervals comparable to other currently available therapeutic options. With the benefit of a long follow up period, performing ASCT at later stages in the treatment course (i.e. following 3 or more prior therapy lines) did not appear to result in inferior survival outcomes; timing of ASCT should therefore be considered on an individual patient basis and in light of other available therapy options for relapsed disease.

Abstract Introduction: Combination therapy for longer periods but at low dose, also called metronomic scheduling, might be an effective manner to treat patients with relapsing myeloma. In particular if the used agents attack the malignant clone in an alternative manner. Therefore we used the combination of bortezomib, dexametasone and daily low dose of oral cyclophosphamide as an induction regimen followed by one year of maintenance therapy consisting of bortezomib and cyclophosphamide. Methods: Relapsing myeloma patients, bortezomib naïve, were treated with three cycles of 1.3 mg/m2 bortezomib at day 1, 4, 8 and 11, cyclophosphamide 50 mg daily, and 20 mg dexamethasone at day 1, 2, 4, 5, 8, 9, 11 and 12 followed by three cycles of bortezomib 1.6 mg/m2 (day 1, 8, 15 and 2), cyclophosphamide (50 mg) daily and dexamethasone (20 mg) at day 1, 2, 8, 9, 15, 16, 22 and 23. Maintenance therapy consisting of bortezomib 1.3 mg/m2 every two weeks and daily dose of 50 mg cyclophosphamide for one year was applied to patients in partial or complete remission. Primary endpoints were toxicity during re-induction and maintenance therapy. Secondary endpoints were response to treatment and progression free and overall survival. Results: 59 patients with relapsing multiple myeloma were included of whom 69% were in first relapse (Table 1). The upfront treatment consisted mainly of thalidomide-based and vincristine-based chemotherapy and 40% of the patients have been treated with an autologous stem cell transplantation. All 6 cycles of induction chemotherapy could be given in 49% of the patients. Premature discontinuation before starting maintenance therapy was due to toxicity (31%), progressive disease (7%), death (7%) or other reasons (6%). Myelosuppression was the most common side effect with WHO grade 3-4 in 31% of the patients. Neuropathy grade 3-4 was observed in 16% of patients, partially due to the fact that bortezomib was given intravenously during the first 2 yrs of the protocol which included 76% of the patients. Maintenance therapy was started in 47% of the patients with a median duration of 7.3 months (range 0.36.-13.4). Grade 3-4 toxicity was observed in 25% of the patients including infections (n=3) and myelosuppression (n=3) which did not resulted in discontinuation of therapy. Median follow up time was 29 months with an overall response of 62%, and a very good partial response (VGPR), complete remission (CR) in 21% and 7% of the patients respectively. During the maintenance phase an improvement in responsiveness was observed in 25% of the patients. The CR rate increased with 9% to a total of 16%. VGPR rate was 20% and 16% of the patient had a PR. At end of the maintenance therapy 50% of patients started with maintenance had stable disease. The median progression free survival (PFS) was 17.2 months (range 0.13 – 43.5) as depicted in figure 1. and the median overall survival was 21.6 months (range 0.46-54.4, figure 2). During follow up 33 % of the patients died due to progression of MM. Conclusion: The present study demonstrates that combination therapy with bortezomib, continuous low dose cyclophosphamide and dexamethasone is an effective and manageable regimen. Adding a year of maintenance was feasible with limited side effects and an increase in CR rate.

425 Background: CA19-9 has been shown to correlate with response to therapy and OS in patients with mPAC. NAPOLI-1, a randomized phase 3 study evaluated nal-IRI, a nanoliposomal formulation of irinotecan, with or without 5-FU/LV vs 5-FU/LV in patients with mPAC previously treated with gemcitabine-based therapy. Nal-IRI+5-FU/LV significantly improved OS (primary endpoint) vs 5-FU/LV (6.1 mo vs 4.2 mo; unstratified hazard ratio [HR] = 0.67; P = 0.012). CA19-9 response (≥50% decline from baseline) was superior with nal-IRI+5FU/LV compared with 5-FU/LV (29% vs 9%; P=0.0006). Nal-IRI alone did not show a statistical improvement in survival. Methods: Patients with a recorded baseline CA19-9 measurement were divided into quartiles to evaluate the treatment effect pattern of CA19-9 from nal-IRI+5-FU/LV and 5-FU/LV arms. Quartile ranges were based on 404 available CA19-9 values from randomized patients (N=417). Unstratified Cox proportional hazards regression was used to estimate HRs and corresponding 95% CIs. Effect of baseline CA19-9 on time to response, progression-free survival, and response will be presented. Results: Of patients randomized to receive nal-IRI+5-FU/LV (n = 117) or 5-FU/LV enrolled contemporaneously (n = 119), 218 received study drug and had a baseline CA19-9 measurement. Results show a greater treatment effect on OS with higher CA19-9 level relative to 5-FU/LV. Conclusions: In patients with mPAC previously treated with gemcitabine-based therapy, nal-IRI+5-FU/LV significantly improved OS supported by progression free survival and objective response rate. The CA19-9 serum level can provide important information with regards to overall survival. Clinical trial information: NCT01494506. [Table: see text]

Abstract Abstract 2917 Background: The European LeukemiaNet MDS (EUMDS) registry is designed to collect information about the demographics and disease-management of newly diagnosed low-risk and intermediate-1 risk MDS patients. From April 2008 until July 2010, 828 patients have been registered in eleven participating countries through a web-based reporting system. Objectives: This report describes the disease-management of the first 800 registered patients, including transfusion-related issues like secondary iron overload and its treatment. Results: 159 of 800 patients (20%) started MDS specific treatment within three months before registration; this percentage increased to 50% at 18 months of follow-up. Most patients received erythroid-stimulating agents (ESA), like erythropoietin (Table 1). In patients with a clinical indication for ESA, the percentage of transfusion-independency was similar to the transfusion-independent group without indication for ESA at 18 months of follow-up (Table 1). Overall, 27% of the patients received blood transfusions at registration. This percentage remained stable during follow-up, probably due to the therapeutic effect of ESA (Table 1). The number of units transfused, per 6 months, in these patients increased from 5 to 13 units at 18 months of follow-up, with a mean pre-transfusion Hb level of 7.6 g/dL. The serum ferritin levels of the transfusion-dependent patients at registration were available in 159 patients. The serum ferritin level at registration was ≥2000 μg/L in 4% of the patients who received a mean number of 10 units (SD 7). This increased to 28% of the patients who received a mean number of 20 units (SD 11) at 18 months of follow-up. The percentage of patients on iron chelation therapy increased from 1% to 9% during follow-up (Table 1). In these patients the mean serum ferritin levels remained stable: 1913 μg/L (SD 1183) at registration and 1626 μg/L (SD 1232) at 18 months of follow-up. In contrast, transfusion-dependent patients not treated with iron chelation or ESA had increasing ferritin levels, with a mean ferritin of 630 μg/L (SD 597) at registration and 1586 μg/L (SD 1017) at 18 months of follow-up. 37 patients (5%) progressed to high-risk MDS or acute myeloblastic leukemia at a median of 155 days from registration. 62 patients (8%) have died within a median of 269 days from registration, 32 deaths were MDS related. The overall survival was 93% at 18 months of follow-up, with a progression-free survival of 90%. Differences in overall survival between transfusion-independent and transfusion-dependent patients were significant: 97% versus 85%, respectively (p<0.0001; Table 2). In the multivariate analysis transfusion-dependency, ferritin levels and IPSS score predicted survival (Table 2). The IPSS score had a significant prognostic impact on overall survival and progression-free survival in contrast to the WHO classification (Data not shown). Conclusions: Despite a high transfusion load the mean serum ferritin levels remained stable during treatment with iron chelation. Transfusion-dependent patients had a worse overall survival and progression-free survival with higher ferritin levels and higher IPSS score as compared to transfusion-independent patients. This report demonstrates the importance of detailed disease-management in low- and intermediate-1 risk MDS patients.

Abstract Abstract 3567 Autologous transplantation significantly improves the progression free survival (PFS) and overall survival (OS) of patients with relapsed or resistant follicular (rFL) lymphoma compared with chemotherapy alone (Schouten H, et al. J Clin Oncol 2003;21:3918–27). Small phase II trials suggest, that rituximab (R) given peritransplant further improves survival outcome. Whilst the role of maintenance R post chemotherapy in FL is established, the benefit and safety of maintenance R following autologous transplant is unknown. In this randomised prospective study the efficacy and safety of R as in vivo purging pretransplant and as maintenance treatment immediately post transplant was assessed. From Oct 1999 to Apr 2006, 280 of a planned 420 R naïve patients with rFL in first (n=16), second (n= 222) or third remission (n=41) who achieved either a complete remission (n=83) or a very good partial remission (n=196) to induction chemotherapy, with limited bone marrow infiltration (<25% B-lymphocytes) underwent a single randomisation in a 2 × 2 design to R purging 375 mg/m2 weekly × 4 (RP) before high-dose therapy with BEAM conditioning (HDC) and maintenance R 375 mg/m2 every 3 months for 2 years (RM). The primary endpoint of the study was PFS. All analysis is by intention to treat. The median age was 51 years (range: 26–70), and baseline characteristics were well balanced between groups. On average patients were 44.1 (range 3.4–463.8) months from diagnosis with 79.3% having 2 lines of therapy and 15% three lines of prior therapy. Patients were equally distributed between low, intermediate and high FLIPI scores. Pretransplant 70% of patients were in PR and 30% in CR. Fifty seven patients failed to mobilise peripheral blood stem cells. Nineteen patients withdrew, 5 due to toxicity, 9 were ineligible. In the 196 (70%) patients transplanted, neutrophil engraftment > 0.5 × 109 /L was prompt, median 14.3 days (range 10–115) and platelets > 50 × 109/L,median 25.1 days (range 9–190). Time to engraftment and early or late toxicities did not differ significantly between the groups apart from a lower neutrophil count at 3 months in patients on maintenance. No graft failures or late neutropenia was reported. Transplant related mortality was 0.5%. Only 3 infection related deaths have been reported post 100 days. Two hundred and seventeen patients are alive on continued follow-up. Median follow-up is 6.4 years. PFS at 5 years was 62.9% for patients receiving RP + RM versus 37.6 % for patients receiving no R (logrank PFS; p=0.004; HR 0.76, 95%CI: 0.66 – 0.93). OS at 5 years was 79.5% % versus 78.4 % for patient receiving RP + RM versus no R (logrank PFS; p>0.1). Multivariate analysis was not able to define a high or low risk patient group. R in vivo purging and maintenance results in superior PFS compared to no R. R does not adversely affect peripheral blood stem cell harvesting or engraftment and maintenance R post transplant is safe. The impressive OS suggests that relapsed FL patients can be effectively salvaged post R purging and maintenance.

Abstract Abstract 3448 Poster Board III-336 Introduction Patients (pts) with CLL have more than twice the risk of developing second malignancies [1]. Frontline therapy with FCR was the strongest independent determinant of survival when compared to FC in patients with CLL in retrospective analysis [2]. This study aims to identify pretreatment factors that may be associated with the development of 2nd malignancies in patients with CLL treated with FCR as initial therapy. Methods Our analysis includes pts with CLL treated between July 1999 and November 2003, on a Phase II trial of FCR as initial therapy. Patients who had developed a 2nd malignancy prior to initiation of therapy were excluded. Patients were divided in 2 groups according to whether they developed a 2nd malignancy during the follow up period. Time to 2nd malignancy was defined as the time from treatment to the first occurrence of 2nd malignancy. Chromosomal abnormalities were detected by metaphase karyotype of bone marrow leukemia cells. Patient characteristics, response to FCR, and overall survival were compared between the two groups using: Wilcoxon rank for continuous variables or Chi-square tests for categorical variables; Kaplan-Meier method was used to generate survival curves and log-rank test was used to assess differences in survival between subgroups. Responses were assessed by 1996 NCI-WG criteria after completion of treatment. Univariate and multivariate Cox proportional hazards model were fitted to assess the association between pts' characteristics and the second malignancy-free survival. Results Among 300 pts with CLL treated with frontline FCR, 46 had a 2nd cancer diagnosed prior to FCR were therefore excluded from this analysis, resulting in a total of 254 pts (85%). With a median follow-up of 76 months, 58 pts (23%) have developed a 2nd malignancy. These included hematological malignancies n=20, non-melanoma skin cancer n=18, solid tumors n=15 and 5 patients have more than 1 type of malignancy. Pts who developed a 2nd malignancy had significantly higher pretreatment percent of lymphocyte in the bone marrow (p=0.04), were less likely to have enlarged spleen size (p=0.024), and were more likely to have deletion of or abnormal chromosome 17 (p=0.008). The overall survival or the responses to treatment were not different between the 2 groups of pts. In the Cox proportional hazards model, abnormalities of chromosome 17 and 13 were statistically significantly associated with shorter time to 2nd malignancy: HR, 9.79 (95% CI, 2.84 - 33.82), p=0.0003 and HR, 4.019 (95% CI, 1.41 - 11.42), p=0.009, respectively. Conclusion Chromosome 17 and 13 abnormalities identified by standard metaphase karyotype analysis were more common in patients with CLL who develop 2nd malignancy after FCR therapy. The response rates and overall survival were not different between patients with CLL with or without 2nd malignancy after frontline therapy with FCR.

Abstract Abstract 1343 Background: Multiple myeloma (MM) is the second most common hematological malignancy in the United States with an estimated 20,580 new cases in 2009. Over the past decade, the introduction of novel agents (thalidomide, lenalidomide and bortezomib) have played a pivotal role in improving response rates, duration of response, overall survival (OS) and quality of life. In this study we describe a single center experience with novel agents used for induction followed by high dose chemotherapy (HDT) and first autologous stem cell transplant (ASCT) in patients with MM. Method: A retrospective review of the medical records of 179 newly diagnosed patients with MM seen between October 2006 and December 2009 at The Ohio State University was performed. All patients received novel therapy containing thalidomide, bortezomib or lenalidomide as part of an induction regimen followed by ASCT. All patients received melphalan 140mg/m2 or 200mg/m2 as preparative regimen. Kaplan-Meier estimates were used to plot progression free survival and overall survival. Results: Of the 181 patients seen, 2 were excluded because they did not receive a novel agent as part of induction treatment. Of the 179 patients analyzed, median age was 56.8 years (29-80) with 30% of patients older than 60 years. African American represented 19%. Fifty-nine percent were male, 80% had Durie-Salmon (DS) stage III while 25%, 28%, 18% represented International prognostic score (IPS) stage I, II, and III respectively with 27% unknown. Median comorbidity index score was 2 (2-7) and median Karnofsky performance score (KPS) was 90% (70-100). Thirty percent had high risk genetic profile, and 73% received one line of treatment before ASCT. The median time from diagnosis to ASCT was 8.33 months (4-58). The overall response rate (ORR) prior to transplant was 84% (9% complete (CR), 29% very good partial (VGPR), and 46% partial (PR)). The ORR post ASCT was 89% (CR 45%, VGPR 22%, PR 21%). Non relapse mortality was 1% and 3% at 100 days and 1 year respectively. At a median follow up of 31 months (7-90), 69 patients (38%) had relapsed. Median progression free survival (PFS) was 29 months with 1 and 3 years PFS of 79.3% and 61.5% respectively (Fig. 1). The OS was not reached. One and 3 years OS were 93% and 88% respectively (Fig. 1). Univariate analysis showed that time to transplant > 12 months was associated with poor outcome and decreased overall survival (HR 3.30, p = 0.008). High risk genetic profile was also found to be associated with decreased overall survival although this was not statistically significant (HR 2.31, p = 0.070). Multivariate analysis found that only time to transplant > 12 months was an independent predictor of decreased OS. Significant predictors for disease progression were high risk genetic profile and time to transplant > 12 months in patients receiving 2 or more treatments before ASCT. Conclusion: Induction with novel agents followed by HDT and ASCT improves CR rate, in our case from 9% to 45%. Median PFS (29 months) was comparable to other published data. OS was not been reached after a median follow up of 31 months. Predictors of progression include high risk genetic profile and time to transplant > 12 months. The only significant predictor for survival was time to transplant. Our study suggests that an early transplant may improve OS and PFS. An extended analysis will be presented at the meeting.

Abstract High cytogenetic risk abnormalities confer poor outcomes in multiple myeloma patients. In POLLUX, daratumumab/lenalidomide/dexamethasone (D-Rd) demonstrated significant clinical benefit versus lenalidomide/dexamethasone (Rd) in relapsed/refractory multiple myeloma (RRMM) patients. We report an updated subgroup analysis of POLLUX based on cytogenetic risk. The cytogenetic risk was determined using fluorescence in situ hybridization/karyotyping; patients with high cytogenetic risk had t(4;14), t(14;16), or del17p abnormalities. Minimal residual disease (MRD; 10–5) was assessed via the clonoSEQ® assay V2.0. 569 patients were randomized (D-Rd, n = 286; Rd, n = 283); 35 (12%) patients per group had high cytogenetic risk. After a median follow-up of 44.3 months, D-Rd prolonged progression-free survival (PFS) versus Rd in standard cytogenetic risk (median: not estimable vs 18.6 months; hazard ratio [HR], 0.43; P < 0.0001) and high cytogenetic risk (median: 26.8 vs 8.3 months; HR, 0.34; P = 0.0035) patients. Responses with D-Rd were deep, including higher MRD negativity and sustained MRD-negativity rates versus Rd, regardless of cytogenetic risk. PFS on subsequent line of therapy was improved with D-Rd versus Rd in both cytogenetic risk subgroups. The safety profile of D-Rd by cytogenetic risk was consistent with the overall population. These findings demonstrate the improved efficacy of daratumumab plus standard of care versus standard of care in RRMM, regardless of cytogenetic risk.

Abstract BACKGROUND: Management of neurofibromatosis type 2 (NF2)—associated vestibular schwannomas (VSs) remains controversial. Stereotactic radiosurgery (SRS) with conventional dosing is less effective for NF2-related VS compared with sporadic lesions. OBJECTIVE: To evaluate optimal SRS dose parameters for NF2-related VS and to report long-term outcomes. METHODS: A prospective database was reviewed and outcome measures, including radiographic progression, American Academy of Otolaryngology—Head and Neck Surgery hearing class, and facial nerve function, were analyzed. Progression-free survival was estimated with Kaplan-Meier methods. Associations between tumor progression and radiosurgical treatment parameters, tumor volume, and patient age were explored with the use of Cox proportional hazards regression. RESULTS: Between 1990 and 2010, 26 patients with 32 NF2-related VSs underwent SRS. Median marginal dose and tumor volume were 14 Gy and 2.7 cm3, respectively. Twenty-seven tumors (84%) showed no growth (median follow-up, 7.6 years). Kaplan-Meier estimates for 5- and 10-year progression-free survival were 85% and 80%, respectively. Cox proportional hazards demonstrated a significant inverse association between higher marginal doses and tumor progression (hazard ratio, 0.49; 95% confidence interval, 0.17-0.92; P = .02). Audiometric data were available in 30 ears, with 12 having class A/B hearing before SRS. Only 3 maintained serviceable hearing at the last follow-up. Four underwent cochlear implantation. Initially, 3 achieved open-set speech recognition, although only 1 experienced long-term benefit. Facial nerve function remained stable in 50% of cases. CONCLUSION: Higher marginal doses than commonly prescribed for sporadic VS were associated with improved tumor control in patients with NF2. Hearing outcomes were poor even when contemporary reduced marginal doses were used. However, SRS allows an anatomically preserved cochlear nerve and may permit hearing rehabilitation with cochlear implantation. Further consideration should be given to optimum dosing to achieve long-term control while maximizing functional outcomes.
