Gene Expression Risk Scores for COVID-19 Illness Severity.

BACKGROUND: The correlates of coronavirus disease 2019 (COVID-19) illness severity following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are incompletely understood. METHODS: We assessed peripheral blood gene expression in 53 adults with confirmed SARS-CoV-2 infection clinically adjudicated as having mild, moderate, or severe disease. Supervised principal components analysis was used to build a weighted gene expression risk score (WGERS) to discriminate between severe and nonsevere COVID-19. RESULTS: Gene expression patterns in participants with mild and moderate illness were similar, but significantly different from severe illness. When comparing severe versus nonsevere illness, we identified >4000 genes differentially expressed (false discovery rate < 0.05). Biological pathways increased in severe COVID-19 were associated with platelet activation and coagulation, and those significantly decreased with T-cell signaling and differentiation. A WGERS based on 18 genes distinguished severe illness in our training cohort (cross-validated receiver operating characteristic-area under the curve [ROC-AUC] = 0.98), and need for intensive care in an independent cohort (ROC-AUC = 0.85). Dichotomizing the WGERS yielded 100% sensitivity and 85% specificity for classifying severe illness in our training cohort, and 84% sensitivity and 74% specificity for defining the need for intensive care in the validation cohort. CONCLUSIONS: These data suggest that gene expression classifiers may provide clinical utility as predictors of COVID-19 illness severity.

A Multicentered Academic Medical Center Experience of a Simulated Root Cause Analysis (RCA) for Hematology/Oncology Fellows.

Quality improvement and patient safety education is an Accreditation Council for Graduate Medical Education (ACGME) common program requirement for hematology/oncology fellowships. Interprofessional clinical patient safety activities, such as root cause analyses (RCA), can be challenging to incorporate into busy schedules. We report on a multicentered experience utilizing a simulated RCA educational module in an attempt to provide fellows with the tools needed to participate in a live RCA and to increase awareness of the need to analyze patient safety events. The 2-h module included a didactic session explaining the basics of an RCA including common terminology, effective chart review, and personal interviews. The fellows assessed a patient safety event of a missed coagulopathy and created an event flow map and fishbone analysis. They then formed root cause/contributing factor statements and proposed a solution. Twenty-three fellows from two institutions completed the experience. There was a significant difference in fellow reported comfort with participating in a live RCA (p = 0.03), and in utilizing the tools of an RCA following the mock RCA experience (p = 0.005). About 70% of respondents felt that as a result of the mock RCA, they were more likely to report a near miss or adverse event and were more likely to be thorough in their documentation. Mock RCAs are a feasible method of incorporating ACGME-required patient safety activities into hematology/oncology fellow education and are effective in increasing their comfort and understanding of important quality improvement skills.

Host Gene Expression in Nose and Blood for the Diagnosis of Viral Respiratory Infection.

BACKGROUND: Recently there has been a growing interest in the potential for host transcriptomic analysis to augment the diagnosis of infectious diseases. METHODS: We compared nasal and blood samples for evaluation of the host transcriptomic response in children with acute respiratory syncytial virus (RSV) infection, symptomatic non-RSV respiratory virus infection, asymptomatic rhinovirus infection, and virus-negative asymptomatic controls. We used nested leave-one-pair-out cross-validation and supervised principal components analysis to define small sets of genes whose expression patterns accurately classified subjects. We validated gene classification scores using an external data set. RESULTS: Despite lower quality of nasal RNA, the number of genes detected by microarray in each sample type was equivalent. Nasal gene expression signal derived mainly from epithelial cells but also included a variable leukocyte contribution. The number of genes with increased expression in virus-infected children was comparable in nasal and blood samples, while nasal samples also had decreased expression of many genes associated with ciliary function and assembly. Nasal gene expression signatures were as good or better for discriminating between symptomatic, asymptomatic, and uninfected children. CONCLSUSIONS: Our results support the use of nasal samples to augment pathogen-based tests to diagnose viral respiratory infection.

Results of the First Clinical Study in Humans That Combines Hyperbaric Oxygen Pretreatment with Autologous Peripheral Blood Stem Cell Transplantation.

Patients undergoing high-dose chemotherapy and autologous hematopoietic cell transplantation (auto-HCT) are at risk for multiple morbidities, including mucosal inflammation and neutropenic fever, both related to neutropenia. Evidence from our preclinical work in an umbilical cord blood (UCB) transplantation murine model suggests that treatment with hyperbaric oxygen (HBO) before UCB infusion improves UCB CD34+ cell engraftment by reducing erythropoietin levels. A pilot clinical trial using HBO in patients undergoing UCB transplantation showed improvement in kinetics of blood count recovery. In this study, we evaluated HBO in combination with auto-HCT. Our primary aim was to determine the safety of HBO in this setting and secondarily to determine its efficacy in reducing time to neutrophil and platelet engraftment compared with matched historic controls. Patients with multiple myeloma, non-Hodgkin lymphoma, and Hodgkin disease eligible for auto-HCT were included. On day 0, patients received HBO treatment consisting of exposure to 2.5 atmosphere absolutes for a total of 90 minutes, in a monoplace hyperbaric chamber, breathing 100% oxygen. Six hours after the start of HBO, peripherally mobilized stem/progenitor cells were infused and patients were followed daily for toxicity and blood count recovery. All patients received daily granulocyte colony-stimulating factor starting on day +5 and until absolute neutrophil count (ANC) of ≥1500 or ANC of 500 for 3 consecutive days. A matched historic cohort of 225 patients who received auto-HCT between January 2008 and December 2012 was chosen for comparison and matched on sex, age, conditioning regimen, and disease type. We screened 26 patients for this study; 20 were treated and included in the primary analysis, and 19 completed the HBO therapy and were included in the secondary analysis. Although the median time to neutrophil count recovery was 11 days in both the HBO and control cohorts, the Kaplan-Meier estimates of the full distributions indicate that the time to neutrophil recovery was generally about 1 day sooner for HBO versus historical controls (log-rank P = .005; range, 9 to 13 for HBO patients and 7 to 18 for controls). The median time to platelet count recovery was 16 days (range, 14 to 21) for HBO versus 18 days (range, 11 to 86) for controls (log-rank P < .0001). In the secondary analysis comparing the HBO cohort who completed HBO therapy (n = 19) with our historical cohort, we evaluated neutropenic fever, growth factor use, mucositis, day +100 disease responses, and blood product use. HBO was associated with less growth factor use (median 6 days in HBO cohort versus median 8 days in controls, P < .0001). Packed RBC and platelet transfusion requirements were not statistically different between the 2 cohorts. Mucositis incidence was significantly lower in the HBO cohort (26.3% in HBO cohort versus 64.2% in controls, P = .002). HBO therapy appears to be well tolerated in the setting of high-dose therapy and auto-HCT. Prospective studies are needed to confirm potential benefits of HBO with respect to earlier blood count recovery, reduced mucositis, and growth factor use, and a cost-benefit analysis is warranted. © 2019 American Society for Blood and Marrow Transplantation.

Long-term results of a pilot study evaluating hyperbaric oxygen therapy to improve umbilical cord blood engraftment.

Umbilical cord blood (UCB) transplantation is a promising option for hematopoietic stem cell transplantation in patients with hematologic malignancies who lack an HLA-matched sibling or well-matched unrelated donor; however, it has a higher incidence of delayed or failed engraftment because cell doses are low and bone marrow homing is inefficient. We have demonstrated that pre-treating irradiated immune-deficient mice with hyperbaric oxygen (HBO) prior to UCB CD34+ cell transplantation lowered host systemic erythropoietin (EPO) and improved UCB CD34+ cell homing and engraftment. These findings suggested that EPO-EPO-R signaling plays a role in UCB CD34+ homing and engraftment. In a pilot clinical trial, we showed that recipients of HBO therapy prior to UCB cell infusion had reduced systemic EPO, which was associated with improved kinetics of blood count recovery. Although early clinical outcomes at day 100 were encouraging, with improved overall survival, the long-term effects of HBO therapy on UCB-transplanted patients were not evaluated. In this study, we examined the long-term outcome of patients in our pilot study, compared with a historic control group, and correlated their clinical outcomes to serum EPO response to HBO. While 50% of HBO-treated patients received single UCB units, ~ 90% of the control patients received double UCB units. Although HBO patients had much better rates of survival at 6 months, their 1-year survival did not significantly differ from the control group. HBO-treated patients had on average lower relapse and non-relapse mortality rates, and less chronic graft versus host disease (GVHD), but had increased acute GVHD. However, these differences were not statistically significant, probably because of the small sample size. In the HBO-treated cohort, immune reconstitution analysis showed significant improvement in early B cell recovery, with a trend toward improvement in early NK cell recovery. When we evaluated the ratio of 8 h to baseline EPO levels, we found a non-significant trend toward lower EPO values in those who neither relapsed nor died by 1 year, compared to those who died or relapsed. This result suggests that EPO response to HBO may be associated with better outcomes. Disease progression-free survival was also improved in those who had more than 80% reduction in EPO levels in response to HBO. Our study highlights the long-term safety of HBO therapy when used prior to UCB transplantation. Future UCB transplant patients who receive HBO should have their serum EPO response measured, as it may be a marker of relapse/mortality.

Systematic Review of Randomized Controlled Trials of Exercise Interventions Using Digital Activity Trackers in Patients With Cancer.

Background: Exercise can ameliorate cancer- and treatment-related toxicities, but poor adherence to exercise regimens is a barrier. Exercise interventions using digital activity trackers (E-DATs) may improve exercise adherence, but data are limited for patients with cancer. We conducted a systematic review examining the feasibility of E-DATs in cancer survivors and effects on activity level, body composition, objective fitness outcomes, health-related quality of life (HRQoL), self-reported symptoms, and biomarkers. Methods: We identified randomized controlled trials (RCTs) of E-DATs in adult cancer survivors published in English between January 1, 2008, and July 27, 2017. Two authors independently reviewed article titles (n=160), removed duplicates (n=50), and reviewed the remaining 110 articles for eligibility. Results: A total of 12 RCTs met eligibility criteria, including 1,450 patients (mean age, 50-70 years) with the following cancers: breast (n=5), colon or breast (n=2), prostate (n=1), acute leukemia (n=1), or others (n=3). Duration of E-DATs ranged from 4 to 24 weeks, and the follow-up period ranged from 4 to 52 weeks, with retention rates of 54% to 95%. The technology component of E-DATs included pedometers (n=8); pedometers with smartphone application (n=1), Wii Fit (n=1), heart rate monitor (n=1); and a wireless sensor with accelerometer, gyroscope, and magnetometer (n=1). Adherence by at least one measure to E-DATs was >70% in 8 of 8 RCTs. Compared with controls, E-DATs significantly improved patients' step count in 3 of 5 RCTs, activity level in 6 of 9 RCTs, and HRQoL in 7 of 9 RCTs (all P≤05), with no significant changes in biomarkers (eg, interleukin 6, tumor necrosis factor α, C-reactive protein, c-peptide, lipid panel) in 3 RCTs. Duration of E-DAT was not significantly correlated with adherence or study retention. Conclusions: This systematic review shows that E-DATs are feasible to implement in cancer survivors. Future research should examine the optimal type, dose, and schedule of E-DATs for cancer survivors.

Evaluation of the clinical impact of concomitant acid suppression therapy in colorectal cancer patients treated with capecitabine monotherapy.

BACKGROUND: Capecitabine is an oral chemotherapeutic agent used in colorectal cancer. Two prior studies found a negative impact with the concomitant use of proton pump inhibitor agents during treatment with capecitabine in patients with early colorectal and gastroesophageal cancers. OBJECTIVE: To determine if there is a clinical impact of the concomitant use of capecitabine and acid suppression therapy in patients with local and metastatic colorectal cancer. METHODS: This was a single-center retrospective cohort study of adult patients with colorectal cancer on capecitabine monotherapy between 2011 and 2017. Progression-free survival (PFS) and overall survival were compared between patients on acid suppression therapy and those not on acid suppression therapy. RESULTS: A total of 70 patients were included. Patients on acid suppression therapy at capecitabine initiation (21%) had decreased progression-free survival versus those not on acid suppression therapy (HR 2.24, 95% CI 1.06-4.41, p = 0.035), after adjusting for disease severity and age. Acid suppression therapy use was associated with a numerical decrease in overall survival (HR 1.86, 95% CI 0.81-3.91, p = 0.14). In patients on any concomitant acid suppression therapy (25%), there was a decreased rate of progression-free survival (HR 6.21, 95% CI 2.56-14.32, p = 0.0001) but not overall survival (HR 1.64, 95% CI 0.68-3.54, p = 0.25) versus those without concomitant acid suppression therapy, after adjusting for age and disease severity. CONCLUSIONS: Concurrent use of acid suppression therapy and capecitabine was associated with decreased progression-free survival, and there was a trend towards decreased overall survival. Due to the demonstrated potential of decreased efficacy, concurrent use of proton pump inhibitors or histamine 2 receptor antagonists should be avoided in colorectal cancer patients on treatment with capecitabine monotherapy.

Phase 2 study of imexon, a prooxidant molecule, in relapsed and refractory B-cell non-Hodgkin lymphoma.

Lymphoma cells are subject to higher levels of oxidative stress compared with their normal counterparts and may be vulnerable to manipulations of the cellular redox balance. We therefore designed a phase 2 study of imexon (Amplimexon/NSC-714597), a prooxidant molecule, in patients with relapsed/refractory B-cell non-Hodgkin lymphoma (NHL). Imexon was administered at 1000 mg/m(2) IV daily for 5 days in 21-day cycles. Gene expression analysis performed on pretreatment tumor specimens included 13 transcripts used to generate a redox signature score, previously demonstrated to correlate with lymphoma prognosis. Twenty-two patients were enrolled having follicular (n = 9), diffuse large B-cell (DLBCL) (n = 5), mantle cell (n = 3), transformed follicular (n = 2), small lymphocytic (n = 2), and Burkitt (n = 1) lymphoma. The most common grade 3/4 adverse events were anemia (14%) and neutropenia (9%). The overall response rate was 30%, including responses in follicular lymphoma (4 of 9) and DLBCL (2 of 5). Gene expression analyses revealed CD68 and the redox-related genes, GPX1 and SOD2, as well as a higher redox score to correlate with clinical responses. Therefore, pretreatment markers of oxidative stress may identify patients likely to respond to this therapeutic approach. This trial was registered at www.clinicaltrials.gov as #NCT01314014.

Serum Procalcitonin Measurement and Viral Testing to Guide Antibiotic Use for Respiratory Infections in Hospitalized Adults: A Randomized Controlled Trial.

BACKGROUND: Viral lower respiratory tract illness (LRTI) frequently causes adult hospitalization and is linked to antibiotic overuse. European studies suggest that the serum procalcitonin (PCT) level may be used to guide antibiotic therapy. We conducted a trial assessing the feasibility of using PCT algorithms with viral testing to guide antibiotic use in a US hospital. METHODS: Three hundred patients hospitalized with nonpneumonic LRTI during October 2013-April 2014 were randomly assigned at a ratio of 1:1 to receive standard care or PCT-guided care and viral PCR testing. The primary outcome was antibiotic exposure, and safety was assessed at 1 and 3 months. RESULTS: Among the 151 patients in the intervention group, viruses were identified in 42% (63), and 83% (126) had PCT values of <0.25 µg/mL. There were no significant differences in antibiotic use or adverse events between intervention patients and those in the nonintervention group. Subgroup analyses revealed fewer subjects with positive results of viral testing and low PCT values who were discharged receiving antibiotics (20% vs 45%; P = .002) and shorter antibiotic durations among algorithm-adherent intervention patients versus nonintervention patients (2.0 vs 4.0 days; P = .004). Compared with historical controls (from 2008-2011), antibiotic duration in nonintervention patients decreased by 2 days (6.0 vs 4.0 days; P < .001), suggesting a study effect. CONCLUSIONS: Although antibiotic use was similar in the 2 arms, subgroup analyses of intervention patients suggest that physicians responded to viral and biomarker data. These data can inform the design of future US studies. CLINICAL TRIALS REGISTRATION: NCT01907659.

Bacterial complications of respiratory tract viral illness: a comprehensive evaluation.

BACKGROUND: Respiratory tract infection is one of the most common reasons for hospitalization among adults, and recent evidence suggests that many of these illnesses are associated with viruses. Although bacterial infection is known to complicate viral infections, the frequency and impact of mixed viral-bacterial infections has not been well studied. METHODS: Adults hospitalized with respiratory illness during 3 winters underwent comprehensive viral and bacterial testing. This assessment was augmented by measuring the serum level of procalcitonin (PCT) as a marker of bacterial infection. Mixed viral-bacterial infection was defined as a positive viral test result plus a positive bacterial assay result or a serum PCT level of ≥ 0.25 ng/mL on admission or day 2 of hospitalization. RESULTS: Of 842 hospitalizations (771 patients) evaluated, 348 (41%) had evidence of viral infection. A total of 212 hospitalizations (61%) involved patients with viral infection alone. Of the remaining 136 hospitalizations (39%) involving viral infection, results of bacterial tests were positive in 64 (18%), and PCT analysis identified bacterial infection in an additional 72 (21%). Subjects hospitalized with mixed viral-bacterial infections were older and more commonly received a diagnosis of pneumonia. Over 90% of hospitalizations in both groups involved subjects who received antibiotics. Notably, 4 of 10 deaths among subjects hospitalized with viral infection alone were secondary to complications of Clostridium difficile colitis. CONCLUSIONS: Bacterial coinfection is associated with approximately 40% of viral respiratory tract infections requiring hospitalization. Patients with positive results of viral tests should be carefully evaluated for concomitant bacterial infection. Early empirical antibiotic therapy for patients with an unstable condition is appropriate but is not without risk.

miRglmm: a generalized linear mixed model of isomiR-level counts improves estimation of miRNA-level differential expression and uncovers variable differential expression between isomiRs.

MicroRNA-seq data is produced by aligning small RNA sequencing reads of different miRNA transcript isoforms, called isomiRs, to known microRNAs. Aggregation to microRNA-level counts discards information and violates core assumptions of differential expression (DE) methods developed for mRNA-seq data. We establish miRglmm, a DE method for microRNA-seq data, that uses a generalized linear mixed model of isomiR-level counts, facilitating detection of miRNA with differential expression or differential isomiR usage. We demonstrate that miRglmm outperforms current DE methods in estimating DE for miRNA, whether or not there is significant isomiR variability, and simultaneously provides estimates of isomiR-level DE.

Response-adapted, time-limited venetoclax, umbralisib, and ublituximab for relapsed/refractory chronic lymphocytic leukemia.

ABSTRACT: Many patients with chronic lymphocytic leukemia (CLL) will develop treatment resistance to Bruton tyrosine kinase (BTK) inhibitors. Phosphatidylinositol-3-kinase (PI3K) inhibitors, including umbralisib, have significant clinical activity in relapsed/refractory CLL, but prolonged exposure is associated with potential toxicities. Owing to the synergistic antitumor effects of combined PI3K and BCL-2 inhibition, we sought to explore the feasibility of response-adapted, time-limited therapy to optimize disease control while mitigating the risks of prolonged treatment. We conducted a phase 1/2 clinical trial to determine the safety and efficacy of venetoclax in combination with umbralisib and the anti-CD20 monoclonal antibody, ublituximab, (U2-VeN) in patients with relapsed/refractory CLL (N = 46) and Richter transformation (N = 5). After 12 cycles, treatment was stopped for patients with CLL who achieved undetectable minimal residual disease (uMRD). Adverse events of special interest included diarrhea in 50% of patients (11% grade 3/4), and aspartate aminotransferase and/or alanine aminotransferase elevation in 15 patients (33%), with 3 (7%) grade 3/4. There were no cases of tumor lysis syndrome related to venetoclax, with outpatient initiation in 96% of patients. The intent-to-treat overall response rate for CLL was 98% with best response of 100% in evaluable patients (42% complete responses). The end-of-treatment rate of uMRD at 10-4 in bone marrow was 77% (30/39), including a 71% uMRD rate among 14 patients refractory to prior BTK inhibitor. Time-limited venetoclax and U2 is safe and highly effective combination therapy for patients with relapsed/refractory CLL including those who have been previously treated with covalent BTK inhibitors. This trial was registered on www.clinicaltrials.gov as #NCT03379051.

Acalabrutinib and high-frequency low-dose subcutaneous rituximab for initial therapy of chronic lymphocytic leukemia.

Bruton tyrosine kinase inhibitors are an effective therapeutic agent for previously untreated patients with chronic lymphocytic leukemia but require indefinite treatment that can result in cumulative toxicities. Novel combinations of agents that provide deep remissions could allow for fixed duration therapy. Acalabrutinib, unlike ibrutinib, does not inhibit anti-CD20 monoclonal antibody-dependent cellular phagocytosis, making it a suitable partner drug to rituximab. Using standard dosing (375 mg/m2) of rituximab causes loss of target membrane CD20 cells and exhaustion of the finite cytotoxic capacity of the innate immune system. Alternatively, using high-frequency, low-dose (HFLD), subcutaneous rituximab limits loss of CD20 and allows for self-administration at home. The combination of HFLD rituximab 50 mg administered twice a week for 6 cycles of 28 days with the addition of acalabrutinib starting in week 2 was evaluated in a phase II study of 38 patients with treatment naive chronic lymphocytic leukemia. Patients achieving a complete response with undetectable minimal residual disease after 12 or 24 cycles of acalabrutinib could stop therapy. All patient responded, including one with a complete response with undetectable minimal residual disease in the peripheral blood and bone marrow at 12 months who stopped therapy. At a median follow-up of 2.3 years 2 patients with high-risk features have progressed while on acalabrutinib monotherapy. We conclude that HFLD rituximab in combination with acalabrutinib is an effective and tolerable self-administered home combination that provides a platform to build upon regimens that may more reliably allow for fixed-duration therapy. This trial was registered at www.clinicaltrials.gov #NCT03788291.

The role of splenectomy in management of splenic B-cell lymphomas.

INTRODUCTION: Splenic B-cell lymphomas are rare and understudied entities. Splenectomy is frequently required for specific pathological diagnosis in patients with splenic B-cell lymphomas other than classical hairy cell leukemia (cHCL), and can be effective and durable therapy. Our study investigated the diagnostic and therapeutic role of splenectomy for non-cHCL indolent splenic B-cell lymphomas. METHODS: Observational study of patients with non-cHCL splenic B-cell lymphoma undergoing splenectomy between 1 August 2011 and 1 August 2021 at the University of Rochester Medical Center. The comparison cohort was patients categorized as having non-cHCL splenic B-cell lymphoma who did not undergo splenectomy. RESULTS: Forty-nine patients (median age 68 years) had splenectomy (SMZL n = 33, HCLv n = 9, SDRPL n = 7) with median follow up of 3.9 years post splenectomy. One patient had fatal post-operative complications. Post-operative hospitalization was ≤ 4 days for 61% and ≤ 10 days for 94% of patients. Splenectomy was initial therapy for 30 patients. Of the 19 patients who had previous medical therapy, splenectomy changed their lymphoma diagnosis in 5 (26%). Twenty-one patients without splenectomy were clinically categorized as having non-cHCL splenic B-cell lymphoma. Nine required medical treatment for progressive lymphoma and of these 3 (33%) required re-treatment for lymphoma progression compared to 16% of patients following first line splenectomy. CONCLUSION: Splenectomy is useful for the diagnosis of non-cHCL splenic B-cell lymphomas with comparable risk/benefit profile and remission duration to medical therapy. Patients with suspected non-cHCL splenic lymphomas should be considered for referral to a high-volume center with experience in performing splenectomies for definitive diagnosis and treatment.

Adaptation of Serious Illness Care Program to be delivered via telehealth for older patients with hematologic malignancy.

Older patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) experience intense inpatient health care at the end-of-life stage. Early advance care planning may improve care at the end of life for patients with AML or MDS. The Serious Illness Care Program (SICP) is a multicomponent, communication intervention developed to improve conversations about values for patients with serious illnesses. The SICP has been shown to improve the quality and frequency of advance care planning discussions. We adapted the SICP for delivery via telehealth to older patients with AML or MDS. We conducted a single-center qualitative study of 45 participants (25 clinicians, 15 older patients with AML or MDS, and 5 caregivers). Participants, whether clinicians, patients, or caregivers, agreed that the SICP would help older patients with AML or MDS to share their personal values with their care team. Four qualitative themes emerged from our data: (1) serious illness conversations can be conducted via telehealth, (2) older patients have limited experience using technology but are willing and able to learn, (3) patients feel that serious illness conversations will help them understand their AML or MDS diagnosis and prognosis better, and (4) serious illness conversations should be common and routine, not extraordinary. The adapted SICP may provide older patients with AML or MDS an opportunity to share what matters most to them with their care team and may assist oncologists in aligning patient care with patient values. The adapted SICP is the subject of an ongoing single-arm pilot study at the Wilmot Cancer Institute (clinicaltrials.gov identifier: NCT04745676).

Advance care planning in older patients with acute myeloid leukemia and myelodysplastic syndromes.

INTRODUCTION: Older patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) have worse survival rates compared to younger patients, and experience more intense inpatient healthcare at the end of life (EOL) compared to patients with solid tumors. Advance care planning (ACP) has been shown to limit aggressive and burdensome care at EOL for patients with AML and MDS. The purpose of this study was to better understand ACP from the perspective of clinicians, older patients with AML and MDS, and their caregivers. MATERIALS AND METHODS: We conducted semi-structured interviews with 45 study participants. Interviews were audio-recorded and transcribed. Open coding and focused content analysis were used to organize data and develop and contextualize categories and subcategories. RESULTS: Guided by our specific aims, we developed four themes: (1) The language of ACP and medical order for life-sustaining treatment (MOLST) does not resonate with patients, (2) There is no uniform consensus on when ACP is currently happening, (3) Oncology clinician-perceived barriers to ACP (e.g., patient discomfort, patient lack of knowledge, and lack of time), and (4) Patients felt that they are balancing fear and hope when navigating their AML or MDS diagnosis. DISCUSSION: The results of this study can be used to develop interventions to promote serious illness conversations for patients with AML and MDS and their caregivers to ensure that patient care aligns with patient values.
