An 8-year pragmatic observation evaluation of the benefits of allogeneic HCT in older and medically infirm patients with AML.

We designed a prospective, observational study enrolling patients presenting for treatment of acute myeloid leukemia (AML) at 13 institutions to analyze associations between hematopoietic cell transplantation (HCT) and survival, quality of life (QOL), and function in: the entire cohort, those aged ≥65 years, those with high comorbidity burden, intermediate cytogenetic risk, adverse cytogenetic risk, and first complete remission with or without measurable residual disease. Patient were assessed 8 times over 2 years. Time-dependent regression models were used. Among 692 patients that were evaluable, 46% received HCT with a 2-year survival of 58%. In unadjusted models, HCT was associated with reduced risks of mortality most of the subgroups. However, after accounting for covariates associated with increased mortality (age, comorbidity burden, disease risks, frailty, impaired QOL, depression, and impaired function), the associations between HCT and longer survival disappeared in most subgroups. Although function, social life, performance status, and depressive symptoms were better for those selected for HCT, these health advantages were lost after receiving HCT. Recipients and nonrecipients of HCT similarly ranked and expected cure as main goal of therapy, whereas physicians had greater expectations for cure than the former. Accounting for health impairments negates survival benefits from HCT for AML, suggesting that the unadjusted observed benefit is mostly owing to selection of the healthier candidates. Considering patients' overall expectations of cure but also the QOL burdens of HCT motivate the need for randomized trials to identify the best candidates for HCT. This trial was registered at www.clinicaltrials.gov as #NCT01929408.

Patient-reported treatment response in chronic graft-versus-host disease.

Chronic graft-versus-host disease (GvHD) treatment response is assessed using National Institutes of Health (NIH) Consensus Criteria in clinical trials, and by clinician assessment in routine practice. Patient-reported treatment response is central to the experience of chronic GvHD manifestations as well as treatment benefit and toxicity, but how they correlate with clinician- or NIH-responses has not been well-studied. We aimed to characterize 6-month patientreported response, determine associated chronic GvHD baseline organ features and changes, and evaluate which patientreported quality of life and chronic GvHD symptom burden measures correlated with patient-reported response. From two nationally representative Chronic GVHD Consortium prospective observational studies, 382 subjects were included in this analysis. Patient and clinician responses were categorized as improved (completely gone, very much better, moderately better, a little better) versus not improved (about the same, a little worse, moderately worse, very much worse). At six months, 270 (71%) patients perceived chronic GvHD improvement, while 112 (29%) perceived no improvement. Patient-reported response had limited correlation with either clinician-reported (kappa 0.37) or NIH chronic GvHD response criteria (kappa 0.18). Notably, patient-reported response at six months was significantly associated with subsequent failure-free survival. In multivariate analysis, NIH responses in eye, mouth, and lung had significant association with 6-month patient-reported response, as well as a change in Short Form 36 general health and role physical domains and Lee Symptom Score skin and eye changes. Based on these findings, patient-reported responses should be considered as an important complementary endpoint in chronic GvHD clinical trials and drug development.

CMV exposure drives long-term CD57+ CD4 memory T-cell inflation following allogeneic stem cell transplant.

Donor and recipient cytomegalovirus (CMV) serostatus correlate with transplant-related mortality that is associated with reduced survival following allogeneic stem cell transplant (SCT). Prior epidemiologic studies have suggested that CMV seronegative recipients (R-) receiving a CMV-seropositive graft (D+) experience inferior outcomes compared with other serostatus combinations, an observation that appears independent of viral reactivation. We therefore investigated the hypothesis that prior donor CMV exposure irreversibly modifies immunologic function after SCT. We identified a CD4+/CD57+/CD27- T-cell subset that was differentially expressed between D+ and D- transplants and validated results with 120 patient samples. This T-cell subset represents an average of 2.9% (D-/R-), 18% (D-/R+), 12% (D+/R-), and 19.6% (D+/R+) (P < .0001) of the total CD4+ T-cell compartment and stably persists for at least several years post-SCT. Even in the absence of CMV reactivation post-SCT, D+/R- transplants displayed a significant enrichment of these cells compared with D-/R- transplants (P = .0078). These are effector memory cells (CCR7-/CD45RA+/-) that express T-bet, Eomesodermin, granzyme B, secrete Th1 cytokines, and are enriched in CMV-specific T cells. These cells are associated with decreased T-cell receptor diversity (P < .0001) and reduced proportions of major histocompatibility class (MHC) II expressing classical monocytes (P < .0001), myeloid (P = .024), and plasmacytoid dendritic cells (P = .0014). These data describe a highly expanded CD4+ T-cell population and putative mechanisms by which prior donor or recipient CMV exposure may create a lasting immunologic imprint following SCT, providing a rationale for using D- grafts for R- transplant recipients.

Multisite 11-year experience of less-intensive vs intensive therapies in acute myeloid leukemia.

Less-intensive induction therapies are increasingly used in older patients with acute myeloid leukemia (AML). Using an AML composite model (AML-CM) assigning higher scores to older age, increased comorbidity burdens, and adverse cytogenetic risks, we defined 3 distinct prognostic groups and compared outcomes after less-intensive vs intensive induction therapies in a multicenter retrospective cohort (n = 1292) treated at 6 institutions from 2008 to 2012 and a prospective cohort (n = 695) treated at 13 institutions from 2013 to 2017. Prospective study included impacts of Karnofsky performance status (KPS), quality of life (QOL), and physician perception of cure. In the retrospective cohort, recipients of less-intensive therapies were older and had more comorbidities, more adverse cytogenetics, and worse KPS. Less-intensive therapies were associated with higher risks of mortality in AML-CM scores of 4 to 6, 7 to 9, and ≥10. Results were independent of allogeneic transplantation and similar in those age 70 to 79 years. In the prospective cohort, the 2 groups were similar in baseline QOL, geriatric assessment, and patient outcome preferences. Higher mortality risks were seen after less-intensive therapies. However, in models adjusted for age, physician-assigned KPS, and chance of cure, mortality risks and QOL were similar. Less-intensive therapy recipients had shorter length of hospitalization (LOH). Our study questions the survival and QOL benefits (except LOH) of less-intensive therapies in patients with AML, including those age 70 to 79 years or with high comorbidity burdens. A randomized trial in older/medically infirm patients is required to better assess the value of less-intensive and intensive therapies or their combination. This trial was registered at www.clinicaltrials.gov as #NCT01929408.

Durable discontinuation of systemic therapy in patients affected by chronic graft-versus-host disease.

Successful treatment of chronic graft-versus-host disease (GvHD) often requires long-term systemic therapy (ST). Durable discontinuation of ST reflects the resolution of active chronic GvHD. We evaluated the factors associated with durable ST discontinuation, defined as cessation of all ST for ≥12 months, using data from two prospectively followed cohorts from the Chronic GvHD Consortium (n=684). Transplant sources were peripheral blood (89%), bone marrow (6.6%), and cord blood (4.4%) from HLA matched related (37.6%), HLA matched unrelated (45%), and other donor types (18%). Half of the patients received non-myeloablative conditioning. The median time from transplantation to chronic GvHD diagnosis was 7.7 months (range, 1.0-141.3) and the median time from chronic GvHD onset to enrollment into the cohorts was 0.9 months (range, 0.0-12.0). The cumulative incidence estimate of durable ST discontinuation was 32% (95% confidence interval: 28%-37%) at 10 years after enrollment into the cohort. Among patients who discontinued ST, the median time from chronic GvHD diagnosis to durable ST discontinuation was 3.6 years (range, 1.2-10.5). In multivariate analysis, patients who received myeloablative conditioning, had chronic GvHD manifested as moderate/severe lower gastrointestinal involvement, and had a higher (worse) Lee symptom overall score were less likely to attain durable ST discontinuation. In contrast, mild lower gastrointestinal involvement and cord blood (vs. peripheral blood) as the graft source were associated with a greater likelihood of ST discontinuation. Although a minority of patients can discontinue ST permanently, most patients require prolonged ST. Viewing chronic GvHD in this way has implications for management approaches.

Germline variation in the insulin-like growth factor pathway and risk of Barrett's esophagus and esophageal adenocarcinoma.

Genome-wide association studies (GWAS) of esophageal adenocarcinoma (EAC) and its precursor, Barrett's esophagus (BE), have uncovered significant genetic components of risk, but most heritability remains unexplained. Targeted assessment of genetic variation in biologically relevant pathways using novel analytical approaches may identify missed susceptibility signals. Central obesity, a key BE/EAC risk factor, is linked to systemic inflammation, altered hormonal signaling and insulin-like growth factor (IGF) axis dysfunction. Here, we assessed IGF-related genetic variation and risk of BE and EAC. Principal component analysis was employed to evaluate pathway-level and gene-level associations with BE/EAC, using genotypes for 270 single-nucleotide polymorphisms (SNPs) in or near 12 IGF-related genes, ascertained from 3295 BE cases, 2515 EAC cases and 3207 controls in the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON) GWAS. Gene-level signals were assessed using Multi-marker Analysis of GenoMic Annotation (MAGMA) and SNP summary statistics from BEACON and an expanded GWAS meta-analysis (6167 BE cases, 4112 EAC cases, 17 159 controls). Global variation in the IGF pathway was associated with risk of BE (P = 0.0015). Gene-level associations with BE were observed for GHR (growth hormone receptor; P = 0.00046, false discovery rate q = 0.0056) and IGF1R (IGF1 receptor; P = 0.0090, q = 0.0542). These gene-level signals remained significant at q < 0.1 when assessed using data from the largest available BE/EAC GWAS meta-analysis. No significant associations were observed for EAC. This study represents the most comprehensive evaluation to date of inherited genetic variation in the IGF pathway and BE/EAC risk, providing novel evidence that variation in two genes encoding cell-surface receptors, GHR and IGF1R, may influence risk of BE.

Reliability and Validity of the Modified 7-Day Lee Chronic Graft-versus-Host Disease Symptom Scale.

Chronic graft-versus-host disease (cGVHD) adversely affects patient quality of life, functional status, and survival after allogenic hematopoietic cell transplantation. The Lee Symptom Scale is a 30-item scale developed to measure the symptoms of cGVHD. Although the original 30-item scale uses a 1-month recall period, we tested the reliability and validity of a 28-item scale (deleting 2 items based on supportive care needs rather than symptoms) with a 7-day recall period, a format that is more appropriate for use in clinical trials. Results show the modified 7-day scale is reliable and valid in the modern era and may be used to assess the symptom burden of cGVHD in clinical trials. Using the distribution method, a 5- to 6-point difference (half a standard deviation) is considered clinically meaningful.

Improving Quality of Life in Hematopoietic Stem Cell Transplantation Survivors Through a Positive Psychology Intervention.

Despite advances in transplantation medicine, psychological distress and quality of life and functional deficits continue to compromise survivorship after hematopoietic stem cell transplantation (HSCT). With increasing numbers of HSCT survivors, supportive oncology interventions that target health-related outcomes in HSCT survivorship are needed. Here we aimed to test the feasibility and acceptability of a group format phone-delivered positive psychology (PP) intervention in HSCT survivors. This is a one-arm pilot study design that adapted and tested an individual PP intervention used in cardiac disease to a phone-delivered group-based program for HSCT survivors who were .4 to 39 years post-transplantation. All participants received an 8-session weekly PP intervention. We assessed feasibility by the enrollment and intervention completion rates. We examined acceptability on a 10-point Likert scale of ease and utility. Unstructured qualitative interviews were used to obtain participant feedback on the intervention for future application in a larger trial. Self-reported assessments on psychological, functional, and quality of life outcomes were administered at baseline and at follow-up (the end of the intervention). Of 64 eligible participants, 29 (45%) enrolled in the study. For the main aim of intervention feasibility and acceptability, participants completed 96% of all PP sessions and rated the ease (7.6 ± 1.7) and utility (8.1 ± 1.1) of sessions highly. Of the self-reported assessments obtained, the PP intervention resulted in improvements in the resilience scale (mean difference, 2.4 ± 5.4; P = .03). From unstructured qualitative interviews, participants reported the PP exercises and intervention helped them to focus on positive emotions and the group format fostered a sense of community and social support. An 8-week phone-delivered group format PP intervention is feasible and acceptable in HSCT survivors. The piloted intervention could be tested with minor modifications in a randomized study to definitively examine the impact of the group format PP intervention on health-related outcomes.

Ixazomib for Treatment of Refractory Chronic Graft-versus-Host Disease: A Chronic GVHD Consortium Phase II Trial.

New interventions are needed in advanced chronic graft-versus-host disease (GVHD). In a phase II, single-arm, multicenter trial, we examined the efficacy of ixazomib in patients with chronic GVHD who had progressed after at least 1 previous line of systemic immunosuppressive (IS) therapy. Ixazomib was given as a 4 mg oral dose weekly on days 1, 8, and 15 of a 28-day cycle for up to 6 total cycles. The primary endpoint was 6-month treatment failure, a composite endpoint including death, relapse, and requirement for an additional line of systemic IS therapy. A total of 50 subjects were enrolled at 6 institutions. The median time from the onset of chronic GVHD to enrollment was 2.8 years (interquartile range, 1.5 to 4.3 years). The degree of chronic GVHD at enrollment was National Institutes of Health (NIH)-defined moderate (16%) or severe (84%), predominantly classic (80% versus 20% overlap), with 52% of patients having involvement of 4 or more organs. The patients were heavily pretreated, with 39 (78%) receiving 3 or more previous lines of systemic therapy for chronic GVHD. Of the 50 patients treated, 26 completed 6 months of planned therapy. The 6-month treatment failure rate was significantly lower than the historical benchmark (28% versus 44%; P = .01) previously established in second-line therapy for chronic GVHD. No patient, transplantation, or chronic GVHD variables were significantly associated with 6-month treatment failure. NIH-defined overall response rate was 40% at 6 months. Overall survival was 92% at 6 months and 90% at 12 months. Ixazomib met the primary endpoint of low treatment failure at 6 months in the setting of advanced chronic GVHD. At 6 months, the NIH-defined rate of complete/partial response was 40%, and 52% of patients remained on ixazomib therapy, suggesting that the low treatment failure rate was due in part due to prevention of progressive disease that would have required additional treatment.

Carfilzomib for Treatment of Refractory Chronic Graft-versus-Host Disease: A Chronic GVHD Consortium Pilot Phase II Trial.

Previously reported experimental and clinical data suggest that proteasome inhibition may have immunomodulatory activity relevant to graft-versus-host disease (GVHD). To explore the safety and activity of carfilzomib in advanced chronic GVHD, we conducted a multicenter pilot phase II trial through the Chronic GVHD Consortium. Carfilzomib was administered at 20 mg/m2 on day 1, then 36 mg/m2 on days 8 and 15 of a 28-day treatment cycle (cycle 1), and then 36 mg/m2 on days 1, 8, and 15 of a 28-day treatment cycle (cycles 2 to 6). The primary endpoint was 6-month treatment failure, a composite endpoint including death, relapse, and requirement for an additional line of systemic immunosuppressive therapy. A total of 20 subjects were enrolled at 4 institutions. The median time from chronic GVHD onset to enrollment was 1.5 years (interquartile range, 0.5 to 3.7 years). Chronic GVHD was National Institutes of Health category moderate (30%) or severe (70%), predominantly classic (90% versus overlap 10%), and involved multiple diverse organ sites. The number of previous lines of systemic therapy for chronic GVHD was ≤2 in 6 patients (30%) and ≥3 in the other 14 (70%). Doses were held primarily for infection (50% of total held doses); only 3 patients (15%) completed all planned doses of the 6 cycles of carfilzomib. Serious adverse effects occurred in 40% of the patients, and 7 patients died, between .3 and 9 months after the last carfilzomib dose, but no deaths were attributed to carfilzomib. The 6-month treatment failure rate was not significantly improved versus the historical benchmark rate (40% versus 44%; P = .36). Overall survival was 80% at 6 months and 65% at 12 months. Failure-free survival at 12 months was 32%. These pilot phase II data suggest that carfilzomib therapy in this advanced chronic GVHD population did not improve over the expected 6-month treatment failure rates achieved under conventional practices and is not recommended for further study for this indication.

Survivorship after Autologous Hematopoietic Cell Transplantation for Lymphoma and Multiple Myeloma: Late Effects and Quality of Life.

Although autologous hematopoietic cell transplantation (AHCT) is standard therapy for patients with lymphoma and multiple myeloma (MM), few studies have addressed late effects and quality of life (QoL) in long-term survivors after AHCT. Using long-term follow-up (LTFU) annual questionnaires with self-reported outcomes, we surveyed 665 patients who were at ≥5 years after AHCT for the diagnosis of lymphoma or MM. Three-hundred and eighty-nine patients completed the questionnaire (58% response rate) at a median of 11 years (range, 5-30 years) after AHCT. The median patient age was 63 years (range, 22-88 years) in the 268 patients with lymphoma and 69 years (range, 34-84 years) in the 121 patients with multiple myeloma. The most commonly reported medical conditions (>10% incidence) were sexual dysfunction, history of shingles, cataracts, osteoporosis or osteopenia, joint replacement, and skin cancer. Current medication use was more frequent in the patients with MM for infection prevention/treatment (19% for MM versus 5% lymphoma; P < .001), hypertension (41% versus 26%; P = .004), osteoporosis (23% versus 10%; P < .001), and pain (32% versus 11%, P < .001). Treated hypothyroidism was more common in lymphoma patients. In multivariate analysis combining lymphoma and MM, worse physical functioning was associated with older age, shorter interval since AHCT, comorbidities, relapse, and treatment for depression and/or pain. Worse mental functioning was associated with younger age and treatment for anxiety, depression, or pain. In conclusion, AHCT survivors report generally good QoL but many late effects and symptoms that are potentially amenable to intervention.

The Chronic Graft-versus-Host Disease Failure-Free Survival (cGVHD-FFS) Index.

In clinical trials of chronic graft-versus-host disease (cGVHD), the need to start a new systemic treatment is considered a treatment failure. A composite endpoint called "failure-free survival" (FFS), where events are initiation of a new systemic cGVHD treatment, recurrent malignancy, and death, has been suggested as a possible long-term indicator of success. The goal of the current study was to identify changes in cGVHD manifestations from baseline to 6 months that could accurately predict subsequent longer-term FFS, thereby making it possible to assess outcomes earlier than would otherwise be possible. We used data from 2 prospective, multicenter, observational studies to develop the cGVHD-FFS index. The cGVHD-FFS index was calculated at 6 months, a typical timepoint for assessment of the primary endpoint of phase II cGVHD trials. Subsequent FFS was only 45% within the next 2 years. We found that changes in the scores for the eyes, joint/fascia, and mouth ulcers from baseline to 6 months were associated with subsequent FFS, but the prognostic accuracy of these changes was not adequate for use in trials. Biomarker studies might help to identify criteria that improve prediction of long-term clinical outcomes in patients with cGVHD.

Employment, Insurance, and Financial Experiences of Patients with Chronic Graft-versus-Host Disease in North America.

Understanding the socioeconomic impact of chronic graft-versus-host disease (GVHD) on affected patients is essential to help improve their overall well-being. Using data from the Chronic GVHD Consortium, we describe the insurance, employment, and financial challenges faced by these patients and the factors associated with the ability to work/attend school and associated financial burdens. A 15-item cross-sectional questionnaire designed to measure financial concerns, income, employment, and insurance was completed by 190 patients (response rate, 68%; 10 centers) enrolled on a multicenter Chronic GVHD Consortium Response Measures Validation Study. Multivariable logistic regression models examined the factors associated with financial burden and ability to work/attend school. The median age of respondents was 56years, and 87% of the patients were white. A higher proportion of nonrespondents had lower income before hematopoietic cell transplantation and less than a college degree. All but 1 patient had insurance, 34% had faced delayed/denied insurance coverage for chronic GVHD treatments, and 66% reported a financial burden. Patients with a financial burden had greater depression/anxiety and difficulty sleeping. Nonwhite race, lower mental functioning, and lower activity score were associated with a greater likelihood of financial burden. Younger age, early risk disease, and higher mental functioning were associated with a greater likelihood of being able to work/attend school. In this multicenter cohort of patients with chronic GVHD, significant negative effects on finances were observed even with health insurance coverage. Future research should investigate potential interventions to provide optimal and affordable care to at-risk patients and prevent long-term adverse financial outcomes in this vulnerable group.

Determining Risk of Barrett's Esophagus and Esophageal Adenocarcinoma Based on Epidemiologic Factors and Genetic Variants.

BACKGROUND & AIMS: We developed comprehensive models to determine risk of Barrett's esophagus (BE) or esophageal adenocarcinoma (EAC) based on genetic and non-genetic factors. METHODS: We used pooled data from 3288 patients with BE, 2511 patients with EAC, and 2177 individuals without either (controls) from participants in the international Barrett's and EAC consortium as well as the United Kingdom's BE gene study and stomach and esophageal cancer study. We collected data on 23 genetic variants associated with risk for BE or EAC, and constructed a polygenic risk score (PRS) for cases and controls by summing the risk allele counts for the variants weighted by their natural log-transformed effect estimates (odds ratios) extracted from genome-wide association studies. We also collected data on demographic and lifestyle factors (age, sex, smoking, body mass index, use of nonsteroidal anti-inflammatory drugs) and symptoms of gastroesophageal reflux disease (GERD). Risk models with various combinations of non-genetic factors and the PRS were compared for their accuracy in identifying patients with BE or EAC using the area under the receiver operating characteristic curve (AUC) analysis. RESULTS: Individuals in the highest quartile of risk, based on genetic factors (PRS), had a 2-fold higher risk of BE (odds ratio, 2.22; 95% confidence interval, 1.89-2.60) or EAC (odds ratio, 2.46; 95% confidence interval, 2.07-2.92) than individual in the lowest quartile of risk based on PRS. Risk models developed based on only demographic or lifestyle factors or GERD symptoms identified patients with BE or EAC with AUC values ranging from 0.637 to 0.667. Combining data on demographic or lifestyle factors with data on GERD symptoms identified patients with BE with an AUC of 0.793 and patients with EAC with an AUC of 0.745. Including PRSs with these data only minimally increased the AUC values for BE (to 0.799) and EAC (to 0.754). Including the PRSs in the model developed based on non-genetic factors resulted in a net reclassification improvement for BE of 3.0% and for EAC of 5.6%. CONCLUSIONS: We used data from 3 large databases of patients from studies of BE or EAC to develop a risk prediction model based on genetic, clinical, and demographic/lifestyle factors. We identified a PRS that increases discrimination and net reclassification of individuals with vs without BE and EAC. However, the absolute magnitude of improvement is not sufficient to justify its clinical use.

No Association Between Vitamin D Status and Risk of Barrett's Esophagus or Esophageal Adenocarcinoma: A Mendelian Randomization Study.

BACKGROUND & AIMS: Epidemiology studies of circulating concentrations of 25 hydroxy vitamin D (25(OH)D) and risk of esophageal adenocarcinoma (EAC) have produced conflicting results. We conducted a Mendelian randomization study to determine the associations between circulating concentrations of 25(OH)D and risks of EAC and its precursor, Barrett's esophagus (BE). METHODS: We conducted a Mendelian randomization study using a 2-sample (summary data) approach. Six single-nucleotide polymorphisms (SNPs; rs3755967, rs10741657, rs12785878, rs10745742, rs8018720, and rs17216707) associated with circulating concentrations of 25(OH)D were used as instrumental variables. We collected data from 6167 patients with BE, 4112 patients with EAC, and 17,159 individuals without BE or EAC (controls) participating in the Barrett's and Esophageal Adenocarcinoma Consortium, as well as studies from Bonn, Germany, and Cambridge and Oxford, United Kingdom. Analyses were performed separately for BE and EAC. RESULTS: Overall, we found no evidence for an association between genetically estimated 25(OH)D concentration and risk of BE or EAC. The odds ratio per 20 nmol/L increase in genetically estimated 25(OH)D concentration for BE risk estimated by combining the individual SNP association using inverse variance weighting was 1.21 (95% CI, 0.77-1.92; P = .41). The odds ratio for EAC risk, estimated by combining the individual SNP association using inverse variance weighting, was 0.68 (95% CI, 0.39-1.19; P = .18). CONCLUSIONS: In a Mendelian randomization study, we found that low genetically estimated 25(OH)D concentrations were not associated with risk of BE or EAC.

Interactive decision support for esophageal adenocarcinoma screening and surveillance.

BACKGROUND: A key barrier to controlling esophageal adenocarcinoma (EAC) is identifying those most likely to benefit from screening and surveillance. We aimed to develop an online educational tool, termed IC-RISC™, for providers and patients to estimate more precisely their absolute risk of developing EAC, interpret this estimate in the context of risk of dying from other causes, and aid in decision-making. RESULTS: U.S. incidence and mortality data and published relative risk estimates from observational studies and clinical trials were used to calculate absolute risk of EAC over 10 years adjusting for competing risks. These input parameters varied depending on presence of the key precursor, Barrett's esophagus. The open source application works across common devices to gather risk factor data and graphically illustrate estimated risk on a single page. Changes to input data are immediately reflected in the colored graphs. We used the calculator to compare the risk distribution between EAC cases and controls from six population-based studies to gain insight into the discrimination metrics of current practice guidelines for screening, observing that current guidelines sacrifice a significant amount of specificity to identify 78-86% of eventual cases in the US population. CONCLUSIONS: This educational tool provides a simple and rapid means to graphically communicate risk of EAC in the context of other health risks, facilitates "what-if" scenarios regarding potential preventative actions, and can inform discussions regarding screening, surveillance and treatment options. Its generic architecture lends itself to being easily extended to other cancers with distinct pathways and/or intermediate stages, such as hepatocellular cancer. IC-RISC™ extends current qualitative clinical practice guidelines into a quantitative assessment, which brings the possibility of preventative actions being offered to persons not currently targeted for screening and, conversely, reducing unnecessary procedures in those at low risk. Prospective validation and application to existing well-characterized cohort studies are needed.

Una Mano Amiga: Pilot Test of a Patient Navigator Program for Southwest New Mexico.

We conducted a pilot test of a patient navigation intervention (Una Mano Amiga) to address cancer health disparities in three rural counties in southwest New Mexico. We trained two bilingual lay health workers (promotoras) as patient navigators (PNs) to help adult cancer patients and their participating families in Grant, Luna, and Hidalgo counties "navigate" the health care system, including appropriate access to social and financial services. Our hypothesized outcome was a reduction in time from diagnosis to treatment initiation compared to the average time without PNs in each of the three counties (2000-2009). We enrolled 85 eligible patients and 43 eligible family members who had completed psychosocial and demographic forms in this PN intervention. Mean time from cancer diagnosis to treatment initiation among 41 study patients was 59.6 days across the three counties. Mean time from non-intervention comparison data was 47.1 days. In the intervention group, on a 0-10 satisfaction scale (higher = more), patient mean scores for three items ranged from 9.3 to 9.6, family members, 8.9-9.3. Caregiver stress as measured by a Caregiver Self-Assessment score ≥ 10 (highest stress = 16) decreased from 23.8% of caregivers at study entry to 14.3% at follow-up (not statistically significantly different). Although the PN intervention did not decrease time from diagnosis to treatment initiation compared to three comparison counties, positive reactions of patients and family members support further research with larger samples.

Quality of Life of Caregivers of Hematopoietic Cell Transplant Recipients.

Caregivers are critical to recipient recovery after hematopoietic cell transplant (HCT); however, little is known about their long-term health and quality of life (QoL). In this study we surveyed 4446 caregiver-recipient pairs in the post-HCT period to describe their QoL and its determinants. In total, 849 caregiver-recipient pairs at a median of 6 years after autologous or allogeneic HCT responded. Among 849 responding caregivers at a median of 6 years post-HCT, 67% of caregivers were women and 68% indicated they were still providing care to the recipient. Mean and median QoL measures of caregivers were at or above general population norms; however, approximately 20% of caregivers reported poor QoL relative to general population norms. Multivariate analysis revealed that caregiver characteristics, including age, gender, and educational attainment, were important determinants of caregiver QoL. Additional determinants of caregiver QoL included recipient QoL, relapse after autologous HCT, and ongoing use of immunosuppression after allogeneic HCT. Additionally, the prevalence of depression and sleep disorders appear to be higher in caregivers than in the general population. We have identified a population of caregivers who may benefit from interventions aimed at improving QoL and health outcomes. HCT clinical practice should also consider caregiver well-being.

Success of Immunosuppressive Treatments in Patients with Chronic Graft-versus-Host Disease.

Moderate to severe chronic graft-versus-host disease (GVHD) is treated with potent immunosuppressive therapy (IST) to modulate the allo-immune response, control symptoms, and prevent further organ damage. We sought to understand the types of treatments used in clinical practice and the likelihood of successful treatment associated with each. A chart review was performed for 250 adult patients at Fred Hutchinson Cancer Research Center enrolled in a prospective observational study. After a median follow-up of 5.6 years for survivors, approximately one-third were still on IST (of whom half were on fourth or greater line of therapy), one-third were alive and off IST, and one-third had relapsed or died. Approximately half of survivors stopped all IST at least once, although half of these restarted IST after a median of 3.4 months (interquartile range, 2.3 to 8.0) off therapy. Successful discontinuation of IST for at least 9 months was associated with myeloablative conditioning (P = .04), more years since transplant (P = .009), and lack of oral (P < .001) and skin (P = .049) involvement compared with those who had to restart IST. We conclude that patients with chronic GVHD usually receive multiple lines and years of IST, with only a third off IST, alive, and free of malignancy at 5 years after chronic GVHD diagnosis. Patients stopping IST should be cautioned to self-monitor and continue close medical follow-up, especially for 3 to 6 months after stopping IST.

PROMIS measures can be used to assess symptoms and function in long-term hematopoietic cell transplantation survivors.

BACKGROUND: Patient-reported outcomes for hematopoietic cell transplantation (HCT) survivors are well characterized with established measures; however, there is little experience with the new, freely available Patient-Reported Outcomes Measurement Information System (PROMIS) measures in this population. The aim of this study was to compare the performance of the PROMIS measures in the HCT setting with the performance of the commonly used 36-Item Short Form Health Survey (SF-36). METHODS: Adult HCT survivors from the Fred Hutchinson Cancer Research Center (n = 4446) were mailed a survey that included the following as part of an annual follow-up survey: the Patient-Reported Outcomes Measurement Information System-Global Health (PROMIS-GH; 10 questions), the 29-Item Patient-Reported Outcomes Measurement Information System Profile (PROMIS-29), and the SF-36. RESULTS: Both the SF-36 and PROMIS measures were available for 1634 HCT recipients (503 autologous recipients and 1131 allogeneic recipients). The overall response rate was 46%. The median time after transplantation for allogeneic and autologous recipients was 12.0 years (range, 0.4-44.1 years) and 6.1 years (range, 0.4-30.1 years), respectively. With the SF-36 or PROMIS-GH, overall physical functioning was somewhat lower in comparison with the general population, but mental functioning was similar. Component and domain scores with similar contents were strongly correlated by Pearson correlation coefficients: the Global Health-Physical and SF-36 Physical Component Summary scores for autologous (r = 0.82) and allogeneic recipients (r = 0.83) and the PROMIS-29 and SF-36 physical function, pain, and vitality/fatigue scores for allogeneic (0.87, -0.82, and -0.82, respectively) and autologous recipients (0.84, -0.82, and -0.81, respectively). The correlation between the Global Health-Mental and SF-36 Mental Component Summary scores was lower (0.70 for autologous recipients and 0.72 for allogeneic recipients). CONCLUSIONS: Physical and mental symptoms and function in autologous and allogeneic HCT survivors can be adequately assessed with PROMIS-29 and PROMIS-GH.
