Abstract Background The purpose of this study was to estimate precise age-specific tubo-ovarian carcinoma (TOC) and breast cancer (BC) risks for carriers of pathogenic variants in RAD51C and RAD51D. Methods We analyzed data from 6178 families, 125 with pathogenic variants in RAD51C, and 6690 families, 60 with pathogenic variants in RAD51D. TOC and BC relative and cumulative risks were estimated using complex segregation analysis to model the cancer inheritance patterns in families while adjusting for the mode of ascertainment of each family. All statistical tests were two-sided. Results Pathogenic variants in both RAD51C and RAD51D were associated with TOC (RAD51C: relative risk [RR] = 7.55, 95% confidence interval [CI] = 5.60 to 10.19; P = 5 × 10-40; RAD51D: RR = 7.60, 95% CI = 5.61 to 10.30; P = 5 × 10-39) and BC (RAD51C: RR = 1.99, 95% CI = 1.39 to 2.85; P = 1.55 × 10-4; RAD51D: RR = 1.83, 95% CI = 1.24 to 2.72; P = .002). For both RAD51C and RAD51D, there was a suggestion that the TOC relative risks increased with age until around age 60 years and decreased thereafter. The estimated cumulative risks of developing TOC to age 80 years were 11% (95% CI = 6% to 21%) for RAD51C and 13% (95% CI = 7% to 23%) for RAD51D pathogenic variant carriers. The estimated cumulative risks of developing BC to 80 years were 21% (95% CI = 15% to 29%) for RAD51C and 20% (95% CI = 14% to 28%) for RAD51D pathogenic variant carriers. Both TOC and BC risks for RAD51C and RAD51D pathogenic variant carriers varied by cancer family history and could be as high as 32–36% for TOC, for carriers with two first-degree relatives diagnosed with TOC, or 44–46% for BC, for carriers with two first-degree relatives diagnosed with BC. Conclusions These estimates will facilitate the genetic counseling of RAD51C and RAD51D pathogenic variant carriers and justify the incorporation of RAD51C and RAD51D into cancer risk prediction models.

Introduction. Myeloid leukemia in children with Down syndrome (ML-DS) is a unique subtype of acute myeloid leukemia, distinguished by an earlier age of onset (under 4 years of age); somatic mutations of GATA1; hypersensitivity of leukemic blasts to cytarabine and other chemotherapeutic agents; lack of CNS involvement; and superior event-free survival (EFS, 85-90% at 5 years). Due to these excellent outcomes, successive protocols by the Children's Oncology Group (COG) have aimed for a reduction of treatment intensity but continue to include a course containing high-dose cytarabine (HD-AraC) for all patients, which is associated with the bulk of infectious toxicity. COG AAML1531 is the first study to evaluate differential treatment for ML-DS patients based on risk-stratification. We report the outcomes for patients with Standard Risk (SR) ML-DS enrolled on AAML1531, who were treated without inclusion of HD-AraC (https://clinicaltrials.gov/ct2/show/NCT02521493?term=AAML1531&rank=1). Methods. Patients older than 90 days and younger than 4 years of age with ML-DS were eligible, including those presenting with myelodysplastic syndrome (< 20% blasts in the bone marrow) and trisomy 21 mosaicism. Pathological and cytogenetic data were reviewed centrally. All patients received the same first course of induction therapy (cytarabine 200 mg/m2/24h IV as continuous infusion, day 1-4; daunorubicin 20 mg/m2IV, day 1-4; thioguanine 50 mg/m2/dose PO twice daily, day 1-4; and a single dose of age-based intrathecal cytarabine on day 1). After this first course, measureable residual disease (MRD) in the bone marrow by multi-dimensional flow cytometry in a reference laboratory was used for risk stratification. Patients with negative MRD (<0.05%) were assigned to Standard Risk (SR) therapy, which was modeled after the AAML0431 predecessor study, but with further reduction of treatment by omission of the course containing HD-AraC/E. coli asparaginase (Induction II of AAML0431). Courses #2 and #3 of SR therapy were identical to the first course except that no further intrathecal chemotherapy was administered. Courses #4 and #5 (cytarabine 100 mg/m2/24h IV as continuous infusion day 1-7; etoposide 125 mg/m2 IV, day 1-3) were identical to the corresponding courses of AAML0431. For patients younger than 36 months, chemotherapy doses were calculated based on weight. Use of dexrazoxane during anthracycline-containing courses was at the discretion of the treating center but was captured by the data collection of the study. Patients with positive MRD (>0.05%) after the first course were assigned to the High Risk (HR) Arm and received intensified therapy (equivalent to that used for non-DS AML). Accrual to the HR arm is ongoing. Results. Interim analysis of SR therapy was performed after 50% of expected EFS events had occurred as of June 30, 2018. The observed EFS was 89.3 +/- 6.1% at 2 years from study entry and significantly lower than expected for comparable MRD-negative patients whose treatment in predecessor study AAML0431 included a course of HD-AraC/E. coliasparaginase (p=0.0002). OS at 2 years was 88.7 +/- 6.8%. Among a total of 114 SR ML-DS patients, 11 developed a relapse, all within the first year from study entry (range 136-327 days). OS at 1 year from relapse was 9.1 +/- 17.3%. Based on the results of interim analysis, the SR arm of AAML1531 was closed to accrual due to lack of efficacy. Cytogenetic analysis showed that complex karyotypes (defined as >3 independent abnormalities including >1 structural one) were significantly more frequent in SR patients who relapsed (40%, n=10) compared to SR patients who did not (9%; n=100; p=0.017). The most common abnormalities were trisomies (61% of cases) of chromosomes 3 and 8, and a gain of a fourth copy of chromosome 21. Monosomy 7 was present in 20% of relapsed vs. 5% of patients without a relapse (p=0.122). Conclusions. MRD measured by multi-dimensional flow cytometry is insufficient to identify a subset of ML-DS patients for whom HD-AraC/E.coliasparaginase can be eliminated from treatment. Cytogenetic profiling may aid in further refining risk-based subsets of ML-DS patients. Additional approaches to risk stratification of ML-DS should be pursued, which take into account the emerging genetic events that co-operate with mutant GATA1 in the development of ML-DS. At this time, HD-AraC/E.coli asparaginase should be included in the treatment of ML-DS, regardless of MRD.

Background Surveillance of sepsis incidence is important for directing resources and evaluating quality-of-care interventions. The aim was to develop and validate a fully-automated Sepsis-3 based surveillance system in non-intensive care wards using electronic health record (EHR) data, and demonstrate utility by determining the burden of hospital-onset sepsis and variations between wards. Methods A rule-based algorithm was developed using EHR data from a cohort of all adult patients admitted at an academic centre between July 2012 and December 2013. Time in intensive care units was censored. To validate algorithm performance, a stratified random sample of 1000 hospital admissions (674 with and 326 without suspected infection) was classified according to the Sepsis-3 clinical criteria (suspected infection defined as having any culture taken and at least two doses of antimicrobials administered, and an increase in Sequential Organ Failure Assessment (SOFA) score by >2 points) and the likelihood of infection by physician medical record review. Results In total 82 653 hospital admissions were included. The Sepsis-3 clinical criteria determined by physician review were met in 343 of 1000 episodes. Among them, 313 (91%) had possible, probable or definite infection. Based on this reference, the algorithm achieved sensitivity 0.887 (95% CI: 0.799 to 0.964), specificity 0.985 (95% CI: 0.978 to 0.991), positive predictive value 0.881 (95% CI: 0.833 to 0.926) and negative predictive value 0.986 (95% CI: 0.973 to 0.996). When applied to the total cohort taking into account the sampling proportions of those with and without suspected infection, the algorithm identified 8599 (10.4%) sepsis episodes. The burden of hospital-onset sepsis (>48 hour after admission) and related in-hospital mortality varied between wards. Conclusions A fully-automated Sepsis-3 based surveillance algorithm using EHR data performed well compared with physician medical record review in non-intensive care wards, and exposed variations in hospital-onset sepsis incidence between wards.

Background: Knowledge regarding the burden and predictors of hypoglycemia among older adults with type 1 diabetes (T1D) is limited. Methods: We analyzed baseline data from the Wireless Innovations for Seniors with Diabetes Mellitus (WISDM) study, which enrolled participants at 22 sites in the United States. Eligibility included clinical diagnosis of T1D, age ≥60 years, no real-time continuous glucose monitoring (CGM) use in prior three months, and HbA1c <10.0%. Blinded CGM data from 203 participants with at least 240 hours were included in the analyses. Results: Median age of the cohort was 68 years (52% female, 93% non-Hispanic white, and 53% used insulin pumps). Mean HbA1c was 7.5%. Median time spent in the glucose range <70 mg/dL was 5.0% (72 min/day) and <54 mg/dL was 1.6% (24 min/day). Among all factors analyzed, only reduced hypoglycemia awareness was associated with greater time spent <54 mg/dL (median time of 2.7% vs 1.3% [39 vs 19 minutes per day] for reduced awareness vs aware/uncertain, respectively, P = .03). Participants spent a mean 56% of total time in target glucose range of 70-180 mg/dL and 37% of time above 180 mg/dL. Conclusions: Over half of older T1D participants spent at least an hour a day with glucose levels <70 mg/dL. Those with reduced hypoglycemia awareness spent over twice as much time than those without in a serious hypoglycemia range (glucose levels <54 mg/dL). Interventions to reduce exposure to clinically significant hypoglycemia and increase time in range are urgently needed in this age group.

PURPOSETo estimate age-specific relative and absolute cancer risks of breast cancer and to estimate risks of ovarian, pancreatic, male breast, prostate, and colorectal cancers associated with germline PALB2 pathogenic variants (PVs) because these risks have not been extensively characterized.METHODSWe analyzed data from 524 families with PALB2 PVs from 21 countries. Complex segregation analysis was used to estimate relative risks (RRs; relative to country-specific population incidences) and absolute risks of cancers. The models allowed for residual familial aggregation of breast and ovarian cancer and were adjusted for the family-specific ascertainment schemes.RESULTSWe found associations between PALB2 PVs and risk of female breast cancer (RR, 7.18; 95% CI, 5.82 to 8.85; P = 6.5 × 10−76), ovarian cancer (RR, 2.91; 95% CI, 1.40 to 6.04; P = 4.1 × 10−3), pancreatic cancer (RR, 2.37; 95% CI, 1.24 to 4.50; P = 8.7 × 10−3), and male breast cancer (RR, 7.34; 95% CI, 1.28 to 42.18; P = 2.6 × 10−2). There was no evidence for increased risks of prostate or colorectal cancer. The breast cancer RRs declined with age ( P for trend = 2.0 × 10−3). After adjusting for family ascertainment, breast cancer risk estimates on the basis of multiple case families were similar to the estimates from families ascertained through population-based studies ( P for difference = .41). On the basis of the combined data, the estimated risks to age 80 years were 53% (95% CI, 44% to 63%) for female breast cancer, 5% (95% CI, 2% to 10%) for ovarian cancer, 2%-3% (95% CI females, 1% to 4%; 95% CI males, 2% to 5%) for pancreatic cancer, and 1% (95% CI, 0.2% to 5%) for male breast cancer.CONCLUSIONThese results confirm PALB2 as a major breast cancer susceptibility gene and establish substantial associations between germline PALB2 PVs and ovarian, pancreatic, and male breast cancers. These findings will facilitate incorporation of PALB2 into risk prediction models and optimize the clinical cancer risk management of PALB2 PV carriers.

Abstract Implanted neural stimulation and recording devices hold vast potential to treat a variety of neurological conditions, but the invasiveness, complexity, and cost of the implantation procedure greatly reduce access to an otherwise promising therapeutic approach. To address this need, a novel electrode that begins as an uncured, flowable prepolymer that can be injected around a neuroanatomical target to minimize surgical manipulation is developed. Referred to as the Injectrode, the electrode conforms to target structures forming an electrically conductive interface which is orders of magnitude less stiff than conventional neuromodulation electrodes. To validate the Injectrode, detailed electrochemical and microscopy characterization of its material properties is performed and the feasibility of using it to stimulate the nervous system electrically in rats and swine is validated. The silicone‐metal‐particle composite performs very similarly to pure wire of the same metal (silver) in all measures, including exhibiting a favorable cathodic charge storage capacity (CSC C ) and charge injection limits compared to the clinical LivaNova stimulation electrode and silver wire electrodes. By virtue of its simplicity, the Injectrode has the potential to be less invasive, more robust, and more cost‐effective than traditional electrode designs, which could increase the adoption of neuromodulation therapies for existing and new indications.

Abstract Background: Patients (pts) with deletion 17p (del17p) CLL follow an aggressive clinical course and experience poor outcomes with chemoimmunotherapy. Ibrutinib, an oral inhibitor of Bruton's tyrosine kinase (BTK), is approved for pts with CLL with ≥1 prior therapy and for pts with del17p CLL (including first-line). In the phase 2 RESONATE-17 study (PCYC-1117), ibrutinib demonstrated high efficacy with a favorable risk-benefit profile in del17p CLL/SLL (O'Brien, ASH 2014). We evaluate the baseline genetic features and prognostic factors of these pts to determine their impact on outcome. Methods: Pts with del17p CLL or SLL defined by peripheral blood FISH who failed ≥1 therapy received 420 mg oral ibrutinib once daily until progression or unacceptable toxicity. Using the primary analysis data cut, the overall response rate (ORR; iwCLL 2008 criteria by investigators), progression-free survival (PFS), and overall survival (OS) were assessed by subgroup. Results: Among 144 treated pts (137 CLL, 7 SLL), the median age was 64 (range 36-89). At baseline, 63% of pts had Rai stage III or IV disease, and 39% had received ≥3 prior therapies. Baseline cytogenetics included del11q (16%), del13q (74%), and trisomy 12 (17%), in addition to del17p in all pts. Of 116 pts with valid baseline genomic samples, IGHV status was unmutated in 84%; genomic variants that included mutations, rearrangements, insertions, deletions, and copy number variants affecting coding regions were identified as follows: ATM (14%), BIRC3 (3%), BTK (1%), MYC (2%), MYD88 (2%), NOTCH1 (16%), PLCG2 (3%), SF3B1 (27%), and TP53 (92%), which were consistent with previously identified mutations in pts with CLL (Wang, NEJM 2011; Winkelmann, Haematologica 2015). At a median follow-up of 11.5 months, the investigator-assessed ORR including partial response with lymphocytosis (PR-L) for all treated pts was 83% (17% PR-L). Median PFS and OS were not reached, with 12-month PFS and OS rates of 79% and 84%. Any-grade adverse events (≥15%) included diarrhea (36%), fatigue (31%), cough (24%), arthralgia (22%), nausea (19%), hypertension (19%), anemia (19%), pyrexia (17%), decreased appetite (17%), muscle spasms (17%), neutropenia (17%), and peripheral edema (15%). Serious AEs occurred in 40% of pts (38% ≥ grade 3). ORR, 12-month PFS, and 12-month OS are presented by subgroup for baseline characteristics, cytogenetics, and genomic variants (Table). There were no substantial differences in response rates and survival outcomes in the subgroups with and without baseline cytogenetic aberrations or genomic variants (Table). Response rates were similar for pts with and without NOTCH1 or SF3B1 variants. Of 11 pts with del17p CLL who developed Richter transformation, baseline aberrations included ATM (n=2), SF3B1 (n=3), and/or NOTCH1 (n=3); none had BIRC3 variants. Overall at baseline, there were 3 pts with a PLCG2 mutation (L163F, H193Q, P236L), and 1 with a BTK mutation (R236Q); all achieved a best overall response of PR-L or better. None had received prior therapy with a BTK or PI3K inhibitor. Two pts had a baseline MYD88 mutation (L265P, L142F) with a best overall response of PR in 1 pt. Two pts had baseline MYC amplifications with 5 of 5 exons amplified to 6 and 7 copies, respectively; 1 pt achieved a best overall response of PR. Conclusions: These results provide further evidence of ibrutinib's robust clinical activity and encouraging survival outcomes in this high-risk population regardless of baseline cytogenetic aberrations or genomic variants. The prognostic role of these clinical characteristics and genetic anomalies will continue to be elucidated with longer term follow-up of this population. Figure 1.

Abstract Background: Patients with chronic lymphocytic leukemia (CLL) with deletion of the short arm of chromosome 17 (del 17p) follow an aggressive clinical course and demonstrate a median survival of less than 2 years in the relapsed/refractory (R/R) setting. Ibrutinib (ImbruvicaTM), a first-in-class Bruton's tyrosine kinase (BTK) inhibitor, has been approved for previously treated patients with CLL and for patients with del 17p CLL. We report results from the primary analysis of the Phase II RESONATETM-17 (PCYC-1117-CA) study, designed to evaluate the efficacy and safety of single-agent ibrutinib for treatment of patients with R/R del 17p CLL or small lymphocytic leukemia (SLL). Methods: Patients with del 17p CLL or SLL who failed at least one therapy were enrolled to receive 420 mg oral ibrutinib once daily until progression. All patients receiving at least one dose of ibrutinib were included in the analysis. The primary endpoint was overall response rate (ORR) per an independent review committee (IRC). Other endpoints included duration of response (DOR), progression-free survival (PFS), and safety of ibrutinib. Results: Among 144 treated patients (137 with CLL, 7 with SLL), the median age was 64 (48% 65 years or older) and all had del 17p. Baseline characteristics included 63% of patients with Rai Stage III or IV disease, 49% with bulky lymphadenopathy of at least 5 cm, and 10% with lymphadenopathy of least 10 cm. The median baseline absolute lymphocyte count (ALC) was 32.9 x 109/L with 57% of patients with a baseline ALC at least 25.0 x 109/L. Baseline beta-2 microglobulin levels were at least 3.5 mg/L in 78% of patients (range 1.8-19.8 mg/L), and lactate dehydrogenase levels were at least 350 U/L in 24% of patients (range 127-1979 U/L). A median of 2 prior therapies (range 1-7) was reported. Investigator-assessed ORR was 82.6% including 17.4% partial response with lymphocytosis (PR-L). Complete response (CR)/complete response with incomplete bone marrow recovery (CRi) were reported in 3 patients. IRC-assessed ORR is pending. At a median follow up of 13.0 months (range 0.5-16.7 months), the median PFS (Figure 1) and DOR by investigator determination had not been reached. At 12 months, 79.3% were alive and progression-free, and 88.3% of responders were progression-free. Progressive disease was reported in 20 patients (13.9%). Richter transformation was reported in 11 of these patients (7.6%), 7 of the cases occurring within the first 24 weeks of treatment. Prolymphocytic leukemia was reported in 1 patient. The most frequently reported adverse events (AE) of any grade were diarrhea (36%; 2% Grade 3-4), fatigue (30%; 1% Grade 3-4), cough (24%; 1% Grade 3-4), and arthralgia (22%; 1% Grade 3-4). Atrial fibrillation of any grade was reported in 11 patients (7.6%; 3.5% Grade 3-4). Seven patients reported basal or squamous cell skin cancer and 1 patient had plasma cell myeloma. Most frequently reported Grade 3-4 AEs were neutropenia (14%), anemia (8%), pneumonia (8%), and hypertension (8%). Major hemorrhage was reported in 7 patients (4.9%, all Grade 2 or 3). Study treatment was discontinued in 16 patients (11.1%) due to AEs with 8 eventually having fatal events (pneumonia, sepsis, myocardial or renal infarction, health deterioration). At the time of data cut, the median treatment duration was 11.1 months, and 101 of 144 patients (70%) continued treatment with ibrutinib. Conclusions: In the largest prospective trial dedicated to the study of del 17p CLL/SLL, ibrutinib demonstrated marked efficacy in terms of ORR, DOR, and PFS, with a favorable risk-benefit profile. At a median follow up of 13 months, the median DOR had not yet been reached; 79.3% of patients remained progression-free at 12 months, consistent with efficacy observed in earlier studies (Byrd, NEJM 2013;369:32-42). The PFS in this previously treated population compares favorably to that of treatment-naïve del 17p CLL patients receiving fludarabine, cyclophosphamide, and rituximab (FCR) (Hallek, Lancet 2010;376:1164-74) or alemtuzumab (Hillmen, J Clin Oncol 2007;10:5616-23) with median PFS of 11 months. The AEs are consistent with those previously reported for ibrutinib (Byrd, NEJM 2014;371:213-23). These results support ibrutinib as an effective therapy for patients with del 17p CLL/SLL.
