Abstract
Abstract
Background: Infection with SARS-CoV-2 has led to a global pandemic and has significantly impacted the care of cancer patients. Breast cancer patients receiving active systemic therapy need protection against COVID19 but the efficacy of vaccines in this population is unknown. Although specific biomarkers associated with protection from SARS-CoV-2 infection have yet to be identified, measurement of serum antibody activity is generally accepted as a surrogate of in vivo humoral response to vaccine. This study evaluates the efficiency and durability of binding antibodies to SARS-CoV-2 spike (S) protein in response to COVID19 vaccine in breast cancer patients receiving systemic treatment. Methods: Breast cancer patients, who were unvaccinated, partially or fully vaccinated with Pfizer-BioNTech BNT162b2 (PF), Moderna mRNA-1273 (Mod) or Johnson & Johnson AD26.COV2.S (J&J) were enrolled in this prospective longitudinal study. Eligible patients were on systemic treatment with cytotoxic chemotherapy, chemotherapy plus a checkpoint inhibitor (CPI), CPI alone or a CDK 4/6 inhibitor. Longitudinal blood samples are being collected at baseline, prior to vaccination in unvaccinated patients (T0), 2 weeks after the first vaccine dose and before the second dose for the mRNA vaccines (T1), 1 month (T2), 3 months (T3), 6 months (T4) and 12 month post vaccination. For J&J, there was no T1 timepoint. Roche Elecsys® Anti-SARS-CoV-2 S receptor binding domain (RBD) antibody immunoassay was used to measure antibody titers (range 0.4 to 250 U/mL). Cut points of <0.8 U/mL = negative, ≥0.8 U/mL = seropositive, were based on validated product specifications. Results: Of the 84 breast cancer patients enrolled, 9 had documented COVID infection at baseline and were excluded from analysis. Mean age was 58 years; 99% were female, 85% were Caucasian, 49% had early stage disease and 51% had metastatic breast cancer. 67% were receiving cytotoxic chemotherapy, 20% a CKD 4/6 inhibitor, 13% a CPI with or without chemotherapy. 61.2% were vaccinated with PF, 34.3% with Mod and 4.5% with J&J vaccines. Seropositivity rate for the entire group was 10% at T0, 78% at T1, 98% at T2 and 100% at T3. Seropositivity rates of all cohorts at different timepoints are shown in the table. Mean titers for all patients were 12.6 U/mL at T0, 102.3 U/mL at T1, 204.4 U/mL at T2 and 214.6 U/mL at T3 timepoints. Similar incremental increase in antibody levels was observed in all cohorts (Table). Conclusions: 78% of the patients with breast cancer on active systemic treatment were seropositive after the first dose of COVID19 vaccine and 98% after the second dose. The antibody response was maintained at 3 months, with 100% seropositivity rate. 6-month antibody response will be available at the time of presentation. Durability of antibody response at 6 and 12 months will help determine the timing of additional vaccine booster doses in this population. Importantly, this study has found that active treatment with chemotherapy, immunotherapy or CDK4/6 inhibitor therapy does not impact antibody response to SARS-CoV-2 vaccination in patients with breast cancer. Table: Seropositivity rate and mean Anti-S protein antibody levels by cohort at each time point. T0= baseline, T1=after first vaccine dose (mRNA vaccines), T2= 4 weeks after 2 doses of mRNA vaccine or after single dose of J&J vaccine, T3=3 months after the first dose of vaccine.

Abstract
Combination immunotherapy with sequential administration may enhance metastatic melanoma (MM) patients with long-term disease control. High Dose Aldesleukin/Recombinant Interleukin-2 (HD rIL-2) and ipilimumab (IPI) offer complementary mechanisms against MM. This phase IV study assessed the sequenced use of HD rIL-2 and IPI in MM patients. Eligible Stage IV MM patients were randomized to treatment with either two courses of HD rIL-2(600,000 IU/kg) followed by four doses of IPI 3 mg/kg or vice-versa. The primary objective was to compare one-year overall survival (OS) with historical control (46%, Hodi et al., NEJM 2010). Secondary objectives were 1-year progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs) profile. Evaluable Population (EP) included patients who received at least 50% of planned treatment with each drug. Thirteen and 16 patients were randomized to receive HD rIL-2 first, and IPI first, respectively. One-year OS rate was 75% for intention to treat population. Eighteen patients were included in EP, 8 in HD rIL-2, 10 in IPI first arm. In EP, 1-year OS, PFS and ORR rates were 87%, 68%, and 50%, respectively. The frequency of AEs was similar in both arms with 13 patients experiencing Grade 3 or higher AEs, 3 resulting in the end of study participation. There was one HD rIL-2-related death, from cerebral hemorrhage due to thrombocytopenia. In this study with small sample size, HD rIL-2 and IPI were safe to administer sequentially in MM patients and showed more than additive effects. 1-year OS was superior to that of IPI alone from historical studies.

Abstract
Background The National Clinical Trials Network program conducts phase 2 or phase 3 treatment trials across all National Cancer Institute’s designated cancer centers. Participant accrual across these clinical trials is a critical factor in deciding their success. Cancer centers that cater to rural populations, such as The University of Kansas Cancer Center, have an additional responsibility to ensure rural residents have access and are well represented across these studies. Objective There are scant data available regarding the factors that act as barriers to the accrual of rural residents in these clinical trials. This study aims to use electronic screening logs that were used to gather patient data at several participating sites in The Kansas University of Cancer Center’s Catchment area. Methods Screening log data were used to assess what clinical trial participation barriers are faced by these patients. Additionally, the differences in clinical trial participation barriers were compared between rural and urban participating sites. Results Analysis revealed that the hospital location rural urban category, defined as whether the hospital was in an urban or rural setting, had a medium effect on enrolment of patients in breast cancer and lung cancer trials (Cohen d=0.7). Additionally, the hospital location category had a medium effect on the proportion of recurrent lung cancer cases at the time of screening (d=0.6). Conclusions In consideration of the financially hostile nature of cancer treatment as well as geographical and transportation barriers, clinical trials extended to rural communities are uniquely positioned to alleviate the burden of nonmedical costs in trial participation. However, these options can be far less feasible for patients in rural settings. Since the number of patients with cancer who are eligible for a clinical trial is already limited by the stringent eligibility criteria required of such a complex disease, improving accessibility for rural patients should be a greater focus in health policy.

Abstract
Many patients with advanced melanoma are resistant to immune checkpoint inhibition. In the ILLUMINATE-204 phase I/II trial, we assessed intratumoral tilsotolimod, an investigational Toll-like receptor 9 agonist, with systemic ipilimumab in patients with anti-PD-1- resistant advanced melanoma. In all patients, 48.4% experienced grade 3/4 treatment-emergent adverse events. The overall response rate at the recommended phase II dose of 8 mg was 22.4%, and an additional 49% of patients had stable disease. Responses in noninjected lesions and in patients expected to be resistant to ipilimumab monotherapy were observed. Rapid induction of a local IFNα gene signature, dendritic cell maturation and enhanced markers of antigen presentation, and T-cell clonal expansion correlated with clinical response. A phase III clinical trial with this combination (NCT03445533) is ongoing. SIGNIFICANCE: Despite recent developments in advanced melanoma therapies, most patients do not experience durable responses. Intratumoral tilsotolimod injection elicits a rapid, local type 1 IFN response and, in combination with ipilimumab, activates T cells to promote clinical activity, including in distant lesions and patients not expected to respond to ipilimumab alone.This article is highlighted in the In This Issue feature, p. 1861.

Abstract
Abstract
Background: BRAF and MEK inhibitors yield objective responses in the majority of BRAFV600E/K mutant melanoma patients, but acquired resistance limits response durations. Preclinical data suggests that intermittent dosing of these agents may delay acquired resistance by deselecting tumor cells that grow optimally in the presence of these agents. S1320 is a randomized phase 2 clinical trial designed to determine whether intermittent versus continuous dosing of dabrafenib and trametinib improves progression-free survival (PFS) in patients with advanced BRAFV600E/K melanoma.
Methods: All patients received continuous dabrafenib and trametinib for 8-weeks after which non-progressing patients were randomized to receive either continuous treatment or intermittent dosing of both drugs on a 3-week-off, 5-week-on schedule. Unscheduled treatment interruptions of both drugs for > 14 days were not permitted. Responses were assessed using RECIST v1.1 at 8-week intervals scheduled to coincide with on-treatment periods for patients on the intermittent dosing arm. Adverse events were assessed using CTCAE v4 monthly. The design assumed exponential PFS with a median of 9.4 months using continuous dosing, 206 eligible patients and 156 PFS events. It had 90% power with a two-sided α = 0.2 to detect a change to a median with an a priori hypothesis that intermittent dosing would improve the median PFS to 14.1 months using a Cox model stratified by the randomization stratification factors.
Results: 242 patients were treated and 206 patients without disease progression after 8 weeks were randomized, 105 to continuous and 101 to intermittent treatment. 70% of patients had not previously received immune checkpoint inhibitors. There were no significant differences between groups in terms of baseline patient characteristics. The median PFS was statistically significantly longer, 9.0 months from randomization, with continuous dosing vs. 5.5 months from randomization with intermittent dosing (p = 0.064). There was no difference in overall survival between groups (median OS = 29.2 months in both arms p = 0.93) at a median follow up of 2 years. 77% of patient treated continuously discontinued treatment due to disease progression vs. 84% treated intermittently (p = 0.34).
Conclusions: Continuous dosing with the BRAF and MEK inhibitors dabrafenib and trametinib yields superior PFS compared with intermittent dosing.

Abstract
Fewer than 5% of cancer patients participate in clinical trials, making it challenging to test new therapies or interventions for cancer. Even within that small number, patients living in inner-city and rural areas are underrepresented in clinical trials. This study explores cancer patients' awareness and perceptions of cancer clinical trials, as well as their perceptions of patient-provider interactions related to discussing cancer clinical trials in order to improve accrual in cancer clinical trials. Interviews with 66 former and current in inner-city and rural cancer patients revealed a lack of awareness and understanding about clinical trials, as well as misconceptions about what clinical trials entail. Findings also revealed that commercials and television shows play a prominent role in forming inner-city and rural patients' attitudes and/or misconceptions about clinical trials. However, rural patients were more likely to hold unfavorable views about clinical trials than inner-city patients. Patient-provider discussions emerged as being crucial for increasing awareness of clinical trials among patients and recruiting them to trials. Findings from this study will inform communication strategies to enhance recruitment to cancer clinical trials by increasing awareness and countering misconceptions about clinical trials.

Abstract
Telehospice, the use of telemedicine technologies to provide services to hospice patients, offers an innovative solution to the challenges of providing high-quality, cost-effective end-of-life care. Specifically, the technology allows caregivers to transmit video images of patients, which provide off-site nurses with the information they need to assist the caregiver. Our telehospice project was conducted in urban and rural Michigan between 2000-2002 and collected data from 187 patients receiving telehospice services in their homes during this study. Overall, nurses were the primary providers of telehospice services and initiated the majority of routine televisits. Often, patients who described themselves as “overwhelmed” at the time of enrollment declined telehospice. However, patients were extremely satisfied with telehospice and often expressed frustration that nurses did not use the telehospice equipment more frequently.

Abstract
New melanoma drugs bring enormous benefits but do so at significant costs. Because melanoma grows deeper and deadlier over time, deeper lesions are costlier due to increased sentinel lymph node biopsy, chemotherapy, and disease-associated income loss. Prior studies have justified pigmented lesion biopsies on a "value per life" basis; by contrast we sought to assess how many biopsies are justified per melanoma found on a purely economic basis. We modeled how melanomas in the United States would behave if diagnosis were delayed by 6 months, eg, not biopsied, only observed until the next surveillance visit. Economic loss from delayed biopsy is the obverse of economic benefit of performing biopsy earlier. Growth rates were based on Liu et al. The results of this study can be applied to all patients presenting to dermatologists with pigmented skin lesions suspicious for melanoma. In-situ melanomas were excluded because no studies to date have modeled growth rates analogous to those for invasive melanoma. We assume conservatively that all melanomas not biopsied initially will be biopsied and treated 6 months later. Major modeled costs are (1) increased sentinel lymph node biopsy, (2) increased chemotherapy for metastatic lesions using increased 5-yr death as metastasis marker, and (3) income loss per melanoma death at $413,370 as previously published. Costs avoided by diagnosing melanoma earlier justify 170 biopsies per melanoma found. Efforts to penalize "unnecessary" biopsies may be economically counterproductive.

Abstract
The objective of this study was to test whether a telehealth intervention could improve the compliance with continuous positive airway pressure (CPAP) by patients with sleep apnea. These patients had been nonadherent for the initial 3 months of therapy even after receiving the initial standard and then supplemental audiotaped/videotaped patient education for adhering to CPAP nightly. The materials and methods included a randomized testing of experimental and placebo interventions. Interventions were delivered by nurses to two groups in their homes by telehealth over a 12-week period. The placebo intervention was used to control for Hawthorne effect, time and attention influences and the novelty of having telehealth in the home. Results following the telehealth interventions were that significantly more patients in the experimental group 1 (n = 10) than the placebo group 2 (n = 9) were adhering nightly to CPAP (chi 2 = 4.55, p = 0.033). Group 1 patients reported greater satisfaction with their intervention. However, both groups rated telehealth delivery positively. The mean cost of each 20-minute telehealth visit was 30 dollars while the total cost of the telehealth intervention for each patient was 420 dollars. These costs included telehealth equipment, initial installation, longdistance telephone charges, nurse salary, and intervention materials. Conclusions are that telehealth interventions are a potentially cost-effective service for increasing adherence to prescribed medical treatments. Replication studies with large samples and in other clinical groups are recommended.

Abstract
BACKGROUND This research was conducted as part of a telehospice study conducted by researchers at Michigan State University, in a partnership with Hospice of Michigan. The study took place from March 2000 through December 2002. OBJECTIVE One of the primary objectives of the study was to learn more about how providers feel about the provision of telemedicine services, in this case telehospice. Of particular importance was learning more about how providers' perceptions of services could change over the course of the project as they became more familiar and comfortable with providing telehospice services. Finally, researchers were interested in how the providers' perceptions of telehospice system might influence utilization. SETTING/SUBJECTS Four Hospice of Michigan offices took part in this telehospice study, two in rural areas and two in urban settings with a total of 187 patients receiving telehospice care. Health providers who offered telehospice services were recruited to share information about their perceptions of the technology. MEASUREMENTS Providers were surveyed at the beginning and end of the project to track their perceptions of telehospice services. Five focus groups with providers were also conducted over the course of the project to allow providers to elaborate their thoughts and perceptions in greater detail. RESULTS Actual utilization of the telehospice system did not have a significant impact on perceptions of services; for the most part, providers began the project with pre-conceived notions about the technology and these perceptions held over the course of the project. Even providers who praised the level of training and technical support and who were able to cite success stories did not display a significant change in attitudes toward telehospice. Providers did express concern regarding how telehospice would impact current aspects of their job such as autonomy or mileage reimbursement. CONCLUSIONS Study results indicate that providers serve as gatekeepers to a new technology and manner of providing care. Telehospice services in this project were primarily provided by a handful of enthusiastic adopters. The results of this study provide important implications if telehospice care is to disseminate for general use among hospice recipients.

Abstract
In 1997, the University of Kansas Medical Center (KUMC) and the United School District 500 (USD 500) in Kansas City, Kansas, launched an innovative telehealth project that brought health care directly into elementary schools by interactive video technology and peripheral devices. This paper focuses on the attitudes and opinions of key players--teachers, nurses, and administrators--involved in providing the service. Research methodology involved analyzing archival data and conducting interviews with key players on the project from USD 500 and KUMC. The study highlights the difficulty in delivering health care, especially telehealth care, to underserved, urban children. The data also reveal that initial challenges and negative attitudes can be overcome to effectively deliver telehealth care in the school setting.

Abstract
In 1997, a telemedicine project began in Kansas which brought health-care directly into elementary schools using interactive video-links. The project initially involved four schools, but was expanded to cover 10 schools, including two middle and one high school. We examined the organizational issues related to telemedicine links to schools. Specific attention was paid to the perceptions of the nurses, teachers and key administrators. The research involved analysing archive data and interviewing participants in the project from the schools and the medical centre. The results showed the difficulties in delivering health-care, especially by telemedicine, to under-served urban children. However, the data also revealed that these can be overcome. Once they had experienced it at first hand, almost all concerned began to see telemedicine as an effective and important asset to the delivery of health-care.

Abstract
We assessed the proportion of home nursing visits that could be replaced by home telenursing in the UK. A retrospective review of nursing notes in the UK was undertaken using an abstraction instrument developed and tested in the US. A total of 1951 episodes of patient care at home were reviewed: 1450 from Liverpool and 501 from Belfast. A total of 1626 (83%) of the episodes involved 'hands-on' interventions. In Belfast two observers estimated that 14% of home nursing visits could be done via telemedicine while in Liverpool two more observers gave an estimate of 16%. Inter-rater agreement was high (kappa = 0.93 for the Belfast observers and 0.79 for the Liverpool observers). Pilot trials of an analogue video-phone in Belfast suggested that even relatively low-quality compressed video might be useful for home nursing. These findings suggest that telemedicine may have a significant role in the delivery of home health care in the UK.

Abstract
Nursing notes for patients nursed at home in the USA and the UK were reviewed using an abstraction instrument developed and tested in the US. More than 1700 episodes of patient care at home were reviewed: 906 in the US and 839 in the UK. Preliminary data suggest that in the US approximately 45% of home nursing visits could be done via telemedicine, while the figure is lower in the UK, less than 15%. Pilot trials of an analogue video-telephone in Kansas City and Belfast suggest that even relatively low-quality compressed video may be useful for home nursing. Clearly, there are differences between the two countries which merit further study, but there is evidence to suggest that telemedicine may have a role in the delivery of home health care.

Abstract
An association between thrombocytopenia and thyrotoxicosis has been previously documented. In addition, a familial association between thrombocytopenia and thyrotoxicosis has also been reported. Theories for etiology include a common immunologic cause, a thyrotoxic-induced decrease in platelet survival, and a genetic predisposition for underlying autoimmune disease. We report a case of autoimmune thrombocytopenic purpura associated with hyperthyroidism in which the patient's thrombocytopenia and thyrotoxicosis resolved concomitantly. We recommend testing for hyperthyroidism in all patients with unexplained thrombocytopenia and that family members of patients be evaluated, screened, and observed for thrombocytopenia and hyperthyroidism.

Abstract
Aplastic anemia is a disorder characterized by pancytopenia and bone marrow hypocellularity. There is some evidence that aplastic anemia may be due to suppression of hematopoiesis by activated T-suppressor cells. Thus, immunosuppressive agents have been used as an alternative to bone marrow transplantation for treatment. We report on a unique case of a patient with aplastic anemia who was treated with a course of immunosuppression including cyclosporine (CSA), anti-thymocyte globulin (ATG), and prednisone. Five months after this treatment, the patient developed a B cell lymphoproliferative disorder which was successfully treated with radiation therapy. Prior reports of CSA-associated lymphoproliferative disorders have appeared in the literature as potential side effects of immunosuppression following transplantation. This is the first report of a lymphoproliferative disorder associated with immunosuppressive treatment of aplastic anemia in a nontransplant setting. Thus, when presenting options for treatment of aplastic anemia, lymphoproliferative disorders should be included as a rare complication of immunosuppressive therapy.
