Background: The PRAETORIAN trial showed non-inferiority of the subcutaneous implantable cardioverter-defibrillator (S-ICD) compared to the transvenous ICD (TV-ICD) with regard to inappropriate shocks and complications. In contrast to the TV-ICD, the S-ICD cannot provide antitachycardia pacing (ATP) for monomorphic ventricular tachycardia (VT). This pre-specified secondary analysis evaluates appropriate therapy and whether ATP reduces the number of appropriate shocks. Methods: The PRAETORIAN trial was an international, investigator-initiated randomized trial, which included patients with an indication for ICD therapy. Patients with prior VTs below 170 bpm or refractory recurrent monomorphic VTs were excluded. In 39 centers, 849 patients were randomized to receive an S-ICD (N=426) or TV-ICD (N=423) and were followed for a median of 49.1 months. ICD programming was mandated by protocol. Appropriate ICD therapy was defined as therapy for ventricular arrhythmias. Arrhythmias were classified as discrete episodes and storm episodes (≥3 episodes within 24 hours). Analyses were performed in the modified intention-to-treat population. Results: In the S-ICD group, 86/426 patients received appropriate therapy, versus 78/423 patients in the TV-ICD group, during a median follow-up of 52 months (48-month Kaplan-Meier estimates 19.4% and 17.5%, P=0.45). In the S-ICD group, 83 patients received at least one shock, versus 57 patients in the TV-ICD group (48-month Kaplan-Meier estimates 19.2% and 11.5%, P=0.02). Patients in the S-ICD group had a total of 254 shocks, compared to 228 shocks in the TV-ICD group (P=0.68). First shock efficacy was 93.8% in the S-ICD group and 91.6% in the TV-ICD group (P=0.40). The first ATP attempt successfully terminated 46% of all monomorphic VTs, but accelerated the arrhythmia in 9.4%. Ten S-ICD patients experienced 13 electrical storms, versus 18 TV-ICD patients with 19 electrical storms. Patients with appropriate therapy had an almost two-fold increased relative risk of electrical storms in the TV-ICD group compared to the S-ICD group (P=0.05). Conclusions: In this trial, no difference was observed in shock efficacy of the S-ICD compared with the TV-ICD. Although patients in the S-ICD group were more likely to receive an ICD shock, the total number of appropriate shocks was not different between the two groups.

Abstract Background: The PTLD-1 trial has demonstrated the efficacy and safety of 4 cycles of weekly rituximab followed by 4 cycles of CHOP-21 + G-CSF in CD20-positive PTLD after solid organ transplantation. Median overall survival (OS) was 6.6 years, a clear improvement over the preceding rituximab monotherapy trials (2.4 years). However, response to rituximab induction predicted OS after completion of therapy. Based on the hypothesis that rituximab consolidation might be sufficient treatment for patients already in a complete response (CR) after rituximab induction, trial treatment was changed in 2007 through a protocol amendment introducing risk-stratified sequential treatment (RSST): rituximab consolidation for patients in CR after rituximab induction and R-CHOP-21 consolidation for all others. Methods: In this international, multicenter phase II trial (PTLD-1, 3rd amendment; NCT00590447), treatment-naïve adult solid organ transplant recipients diagnosed with CD20-positive PTLD were treated with rituximab (375 mg/m2 IV) on days 1, 8, 15 and 22. After restaging, patients in CR continued with four three-weekly courses of rituximab monotherapy while all others received 4 cycles of R-CHOP-21 + G-CSF. In case of disease progression during rituximab monotherapy R-CHOP was commenced immediately. The primary endpoint was treatment efficacy measured as response rates and response duration. Analysis was by intention to treat. This is the final analysis of 152 patients treated with RSST from 2007 to 2014 at centers in Germany (72), Belgium (36), France (24), Australia (7), Poland (7) and Italy (6) with a median follow-up of 4.5 years. The 70 patients treated with rituximab followed by CHOP-21 in the original PTLD-1 trial (median follow-up 5.1 years) served as a control population. Inclusion criteria and follow-up schedule were identical; there were no significant differences in the transplant- and lymphoma-related baseline factors listed below. Results: 115/152 patients were male. 69/152 were kidney, 40 liver, 18 lung, 15 heart, 5 heart/kidney, 3 kidney/pancreas and 2 heart/lung transplant recipients. Median age at diagnosis was 56 years. PTLD was late (> 1 year after transplantation) in 120/152 (79%) of patients. 67/145 (46%) PTLD were EBV-associated. 130/152 patients had monomorphic, 20 polymorphic and 2 early lesion PTLD. The overall response rate (ORR) was 111/126 (88%, CR: 88/126 [70%]). Median duration of remission (DR) was not reached; the 3-year Kaplan-Meier estimate was 82% (compared to 71% in PTLD-1). In the intention-to-treat population (152 patients), the median time to progression (TTP) was not reached either. The 3-year Kaplan-Meier estimate was 78% (69% in PTLD-1). Median OS by intention-to-treat was 6.6 years (95% CI 5.5 - 7.6) with a 3-year estimate of 70% in comparison to 61% in PTLD-1. There was no significant difference in ORR, DR, TTP or OS between EBV-positive and EBV-negative PTLD. On the other hand, response to 4 applications of rituximab was a highly significant predictor of OS, TTP and progression-free survival (PFS) despite treatment stratification (all p<0.001). 37/148 patients (25%) achieved CR with 4 cycles of rituximab and were allocated to rituximab consolidation. In this group, TTP in the intention-to-treat population was significantly longer than in the corresponding group in the PTLD-1 trial (37 patients versus 14 patients, p<0.05). In the 111 patients allocated to R-CHOP consolidation, ORR was 78/92 (85%) with 55/92 (60%) complete remissions (89% and 60%, respectively, in PTLD-1). Median TTP was not reached, the 3-year estimate was 73% (69% in PTLD-1). In patients refractory to rituximab induction, the CR rate was 22/38 (58%) with R-CHOP compared to 3/11 (27%) in PTLD-1 with CHOP (p=0.07); median PFS was 1.4 years versus 0.3 years in PTLD-1, p<0.05. The frequency of grade 3/4 leukopenia and infections was 63% and 34%, respectively. Treatment-related mortality occurred in 7%. Conclusions: This largest trial cohort in PTLD to date demonstrates for the first time that treatment stratification by response to rituximab induction is feasible, safe and effective. Rituximab consolidation in early rituximab responders results in significantly better disease control compared to CHOP consolidation. The addition of rituximab to CHOP chemotherapy improves outcome in patients refractory to rituximab monotherapy.

6003 Background: GP regimen has been established as the standard first-line treatment option for patients with recurrent/metastatic NPC. However, its efficacy in locoregionally advanced disease remains unclear. Methods: Patients with previously untreated, non-metastatic stage III-IVB (except T3-4N0M0, AJCC 7th) NPC, aged 18–64 years without severe comorbidities were eligible. They were randomly assigned (1:1) to receive GP IC (gemcitabine 1 g/m2on days 1 & 8, cisplatin 80 mg/m2 on day 1, q3w for 3 cycles) plus CCRT (cisplatin 100 mg/m2, q3w for 3 cycles, concurrently with intensity-modulated radiotherapy) or CCRT alone. The primary endpoint was failure-free survival (FFS). The calculated sample size was 238 per group, with an 80% power (two-sided α 0.05) to detect a treatment failure hazard ratio (HR) of 0.52. Results: From Dec 2013 to Sep 2016, 480 patients from 12 centers were randomly assigned to IC+CCRT (n = 242) or CCRT alone (n = 238) group. Baseline characteristics were well balanced. After a median follow-up of 39 months, 3-year FFS was 85.8% in the IC+CCRT group and 77.2% in the CCRT alone group (intention-to-treat population; HR 0.53, 95% confidence interval 0.34–0.81; P = 0.003). In GP+CCRT group, 239 patients started GP IC and 231 (96.7%) completed all three cycles. The most common ≥grade 3 adverse events (AE) in IC+CCRT and CCRT group were mucositis (28.9% vs. 32.1%), neutropenia (28.0% vs. 10.5%) and leukopenia (26.4% vs. 20.3%). Conclusions: Adding GP IC to CCRT significantly improved FFS in locoregionally advanced NPC and is well tolerated with favorable toxicity profile. Clinical trial information: NCT01872962.

Background. Due to underrepresentation of patients with chronic kidney disease (CKD) in large Implantable-Cardioverter Defibrillator (ICD) clinical trials, the impact of ICD remains uncertain in this population.Methods. Consecutive patients who received ICD at Creighton university medical center between years 2000–2004 were included in a retrospective cohort after excluding those on maintenance dialysis. Based on baseline Glomerular filtration rate (GFR), patients were classified as severe CKD: GFR < 30 mL/min; moderate CKD: GFR: 30–59 mL/min; and mild or no CKD: GFR ≥ 60 mL/min. The impact of GFR on appropriate shocks and survival was assessed using Kaplan-Meier method and Generalized Linear Models (GLM) with log-link function.Results. There were 509 patients with a mean follow-up of 3.0 + 1.3 years. Mortality risk was inversely proportional to the estimated GFR: 2 fold higher risk with GFR between 30–59 mL/min and 5 fold higher risk with GFR < 30 mL/min. One hundred and seventy-seven patients received appropriate shock(s); appropriate shock-free survival was lower in patients with severe CKD (GFR < 30) compared to mild or no CKD group (2.8 versus 4.2 yrs).Conclusion. Even moderate renal dysfunction increases all cause mortality in CKD patients with ICD. Severe but not moderate CKD is an independent predictor for time to first appropriate shock.

In order to test the toxicity and efficacy of intensive postremission therapy with high-dose cytosine arabinoside with L-asparaginase and amsacrine with etoposide in adults with acute nonlymphocytic leukemia (ANL), 100 adults (ages 19 to 75) with previously untreated ANL were entered into a study using six sequential cycles of chemotherapy. Cycles 1 (induction), 3, and 5 included conventional doses of daunomycin, cytosine arabinoside, 6-thioguanine, vincristine (VCR), and prednisone. Cycle 2 was cytosine arabinoside 3 g/m2 intravenously (IV) every 12 hours for four doses, followed by L-asparaginase 10,000 U intramuscularly (IM) at hour 42; this combination was repeated 1 week later. Cycle 4 included amsacrine 120 mg/m2/d and etoposide 100 mg/m2/d, both IV for five days, and cycle 6 was three monthly courses of VCR on day 1, and prednisone, mercaptopurine, and methotrexate each for five days. Seventy-four patients (74%) achieved complete remission (CR) (51 with cycle 1 and 23 after cycle 2). The overall disease-free survival (DFS) for patients achieving CR is 27% at 3 years by Kaplan-Meier analysis, while for patients achieving CR with cycle 1 it is 34%. The actuarial probability of being free from relapse at 3 years for patients achieving CR is 34%. Sixteen of the 74 CR patients (22%) died in CR while continuing to receive intensive chemotherapy, including 12 (18%) who succumbed to infection (nine bacterial, three fungal). After a median follow-up of 20 months, 36 patients have relapsed and 21 remain alive in CR. Intensive consolidation with high-dose cytosine arabinoside, amsacrine, and etoposide can modestly prolong DFS compared with historical controls. However, relapse continued to be a major problem and, in addition, with more aggressive consolidation therapy, infection during marrow aplasia resulted in a significant number of deaths.

Abstract Background: The initial report of the CREST phase 2 study (Br J Haematol2004;127:165–72) demonstrated the substantial activity of bortezomib (VELCADE®, Vc) at two different dose levels in patients with relapsed or refractory multiple myeloma (MM). Here, we provide an updated analysis of overall survival (OS) after prolonged follow-up (median >5 years). Methods: 54 patients were enrolled to receive Vc 1.0 mg/m2 (n=28) or 1.3 mg/m2 (n=26) on days 1, 4, 8, and 11 of a 21-day cycle, for up to 8 cycles. Dexamethasone (dex) 20 mg on the day of and day after each Vc dose was added for 16 (57%) patients in the 1.0 mg/m2 group and 12 (46%) patients in the 1.3 mg/m2 group, upon suboptimal response to Vc alone. A total of 17 (31%) patients continued to receive Vc ± dex in an extension study, 12 (43%) from the 1.0 mg/m2 and 5 (19%) from the 1.3 mg/m2 groups. Patients received a median of 3 (range, 1–7) prior regimens. Median time from diagnosis to first Vc dose was 2 years. In the 1.0 and 1.3 mg/m2 groups, respectively, mean age was 64 vs 60 years, 50% vs 35% of patients were male, 54% vs 65% had IgG MM, 58% vs 48% had β2-microglobulin ≥4 mg/L, and 29% vs 48% had abnormal cytogenetics. Response rate (CR+PR, EBMT criteria) to Vc alone was 30% vs 38%, and to Vc ± dex was 37% vs 50% in the 1.0 and 1.3 mg/m2 groups. OS from first dose of Vc in each dose group was analyzed using the Kaplan-Meier method. Results: Median OS in the 1.0 and 1.3 mg/m2 groups was 26.8 months and 60.0 months, after median follow-up of 61 and 65 months, respectively (Figure). In the 1.0 mg/m2 group, 21 (75%) patients have died; the 1- and 2-year OS rates were 82% and 54%, respectively. In the 1.3 mg/m2 group, only 14/26 (54%) patients have died; 1- and 2-year OS rates were 81% and 69%, respectively. Conclusions: Vc ± dex was active in relapsed or refractory MM at both the 1.0 mg/m2 and 1.3 mg/m2 dose levels and was associated with notable OS, particularly in patients treated with the approved Vc dose of 1.3 mg/m2. The difference in OS between dose groups suggests that the higher dose of Vc is more active. Figure. Kaplan-Meier analyses of OS in patients who received Vc 1.0 mg/m2 (n=28) or 1.3 mg/m2 (n=26).

559 Background: The increase in survival seen in recent years in patients with mCRC has been attributed to improvements in treatments, including the introduction of targeted biologic agents. The objectives of this retrospective, observational study are to investigate recent treatment patterns in US mCRC patients and examine real-world survival outcomes. Methods: Data were obtained from a large U.S. database (SDI/IMS Health) of mCRC patients diagnosed from January 1, 2004 to June 30, 2011, ≥18 y at diagnosis, and who received chemotherapy and/or biologic treatment. Complete follow-up was defined as those who either died before June 2011 or who had at least 1 claim within 30 days of June 30, 2011. Kaplan-Meier curves were generated to determine overall survival (OS) from the date of mCRC diagnosis. Results: 1,066 stage IV mCRC patients with complete follow-up were identified (57.5% male; mean age, 61.6 y). Approximately 80% were diagnosed with mCRC after 2006; 51.7% had liver metastases. The most common 1L, 2L, and 3L regimens were FOLFOX plus bevacizumab (34.52%), FOLFIRI plus bevacizumab (21.83%), and irinotecan plus cetuximab (15.83%), respectively. A total of 445 patients died during the study period, yielding a mortality rate of 41.74%. Mean time from diagnosis to first treatment was 3.31 months (SD=7.13). All patients received 1L therapy; OS from diagnosis was 35.77 months (95% CI: 32.57-38.10); 5-year survival was approximately 28%. After 1L, 591/1066 (55%) patients went on to receive 2L therapy; for these patients, median survival from diagnosis was 37.13 months (95% CI: 34.07-40.43) and 5-year survival was approximately 25%. After 2L, 278/591 (47%) patients received 3L therapy; for these patients, median survival from diagnosis was 38.10 months (95% CI: 34.83-43.13); 5-year survival was approximately 25%. Conclusions: In this study, OS (35.77 months) was longer than for other mCRC observational studies that have reported survival from start of treatment, but is more comparable when the ~3 months from diagnosis to start of treatment are not included. Addition of targeted agents and novel chemotherapy has prolonged OS in mCRC patients. Because of poor 5-year survival rates, the need for additional agents in later lines of therapy still exists.

426 Background: Locoregional management of muscle-infiltrating bladder cancer (MIBC) after neoadjuvant chemotherapy (NAC) is controversial, because of both the morbidity of radical cystectomy (RC). Bladder preservation may be feasible after complete tumor response. Methods: This single-center retrospective study included 120 MIBC patients (stages ypT2-4aN0-3M0) treated between 2011 and 2017 with up to 6 cycles of neoadjuvant dose-dense Methotrexate, Vinblastin, Doxorubicin and Cisplatin (DD-MVAC). The primary outcome was relapse-free survival (RFS) depending on pathological findings on RC specimens, classified as either pathological complete response (pCR: ypT0N0/x), residual organ-confined disease (yOCD: ypTa/is/1/2N0/x), residual non-organ-confined disease (yNOCD: ypT≥3Nany or ypTanyN1-3). Secondary objectives included the rate of pCR in RC patients, the rate of ypT0 in the intention-to-treat population, and RFS in ypT0 patients according to locoregional management. Results: After a median number of 5 cycles of NAC, RC was performed in 75% of the patients, concurrent radiochemotherapy (CRC) in 11% and cystoscopic surveillance (CS) in 8%. In the intention-to-treat population, the ypT0 rate was 47%. Among 90 patients who underwent RC, 49% achieved pCR, 16% had yOCD and 34% yNOCD. Median follow-up in RC patients alive at last follow-up was 40 months. Three-year RFS was 86% in RC patients with pCR, 69% in patients with yOCD and 21% in patients with yNOCD (p < 0.0001). Outcomes were similar between ypT0 patients treated with either RC or CRC/CS (3-year RFS: 81% vs 100%, p = 0.20). Limitations to this study included its restrospective design and the lower number of patients treated with CRC/CS. Conclusions: Patients reaching ypT0 after dose-dense NAC show improved prognosis regardless of locoregional treatment. Patients with yOCD are frequently cured by RC, as opposed to patients with yNOCD. Prospective trials are needed to compare upfront cystectomy and bladder-sparing management in patients with both pCR or yNOCD.

Abstract There are no data on the role of postconsolidation therapy with gemtuzumab ozogamicin (GO; Mylotarg) in children with acute myeloid leukemia (AML). The NOPHO-AML 2004 protocol studied postconsolidation randomization to GO or no further therapy. GO was administered at 5 mg/m2 and repeated after 3 weeks. We randomized 120 patients; 59 to receive GO. Survival was analyzed on an intention-to-treat basis. The median follow-up for patients who were alive was 4.2 years. Children who received GO showed modest elevation of transaminase and bilirubin without signs of veno-occlusive disease. Severe neutropenia followed 95% and febrile neutropenia 40% of the GO courses. Only a moderate decline in platelet count and a minor decrease in hemoglobin occurred. Relapse occurred in 24 and 25 of those randomized to GO or no further therapy. The median time to relapse was 16 months versus 10 months (nonsignificant). The 5-year event-free survival and overall survival was 55% versus 51% and 74% versus 80% in those randomized to receive GO or no further therapy, respectively. Results were similar in all subgroups. In conclusion, GO therapy postconsolidation as given in this trial was well tolerated, showed a nonsignificant delay in time to relapse, but did not change the rate of relapse or survival (clinicaltrials.gov identifier NCT00476541).

Abstract BACKGROUND There are currently no published data directly comparing postoperative seizure incidence following endoscopic third ventriculostomy (ETV), with/without choroid plexus cauterization (CPC), to that for ventriculoperitoneal shunt (VPS) placement. OBJECTIVE To compare postoperative epilepsy incidence for ETV/CPC and VPS in Ugandan infants treated for postinfectious hydrocephalus (PIH). METHODS We performed an exploratory post hoc analysis of a randomized trial comparing VPS and ETV/CPC in 100 infants (&lt;6 mo old) presenting with PIH. Minimum follow-up was 2 yr. Variables associated with and the incidence of postoperative epilepsy were compared (intention-to-treat) using a bivariate analysis. Time to first seizure was compared using the Kaplan–Meier method, and the relative risk for the 2 treatments was determined using Mantel-Haenszel hazard ratios. RESULTS Seizure incidence was not related to age (P = .075), weight (P = .768), sex (P = .151), head circumference (P = .281), time from illness to hydrocephalus onset (P = .973), or hydrocephalus onset to treatment (P = .074). Irritability (P = .027) and vision deficit (P = .04) were preoperative symptoms associated with postoperative seizures. Ten (10%) patients died, and 20 (20%) developed seizures over the follow-up period. Overall seizure incidence was 9.4 per 100 person-years (9.4 and 9.5 for ETV/CPC and VPS, respectively; P = .483), with no significant difference in seizure risk between groups (hazard ratio, 1.02; 95% CI: 0.42, 2.45; P = .966). Mean time to seizure onset was 8.5 mo for ETV/CPC and 11.2 mo for VPS (P = .464). As-treated, per-protocol, and attributable-intervention analyses yielded similar results. CONCLUSION Postoperative seizure incidence following treatment of PIH was 20% within 2 yr, regardless of treatment modality.

Abstract Aims To explore the association between resting heart rate (RHR) and ventricular tachyarrhythmias (VTA) events among patients who were enrolled in MADIT-RIT. Methods and results Multivariate Cox proportional hazards regression modelling was employed to evaluate the association between baseline RHR [dichotomized at the lower quartile (≤63 b.p.m.) and further assessed as a continuous measure] and the risk for any VTA, fast VTA (&gt;200 b.p.m.), and appropriate implantable cardioverter-defibrillator (ICD) therapy, among 1500 patients who were enrolled in MADIT-RIT. Kaplan–Meier survival analysis showed that at 2 years of follow-up the rate of any VTA was significantly lower among patients with low baseline RHR (≤63 b.p.m.) as compared with faster RHR (11% vs. 19%, respectively; P = 0.001 for the overall difference during follow-up). Similar results were shown for the association with the rate of fast VTA (8% vs. 14%, respectively; P = 0.016), and appropriate ICD therapy (10% vs. 18%, respectively; P = 0.004). Multivariate analysis, after adjustment for medical therapy, showed that low baseline RHR was associated with a significant 45% (P = 0.002) reduction in the VTA risk as compared with faster baseline RHRs. When assessed as a continuous measure, each 10 b.p.m. decrement in RHR was associated with a corresponding 13% (P = 0.014) reduction in the VTA risk. Conclusion In MADIT-RIT, low RHR was independently associated with a lower risk for life-threatening arrhythmic events. These findings suggest a possible role for RHR for improved selection of candidates for ICD therapy.
