Survival Outcomes in Older Adult Acute Lymphoblastic Leukemia Patients Analyzed by Facility Volume and Type: A National Cancer Database Analysis.

BAKGROUND: It is important to understand the outcomes of adult acute lymphoblastic leukemia (ALL) patients at different facilities as treatment paradigms change. AIMS: Our primary objective was to determine adult ALL overall survival (OS) by facility volume and type. Secondary objectives included identifying sociodemographic factors that may have impacted outcomes and analyzing treatment patterns by facility volume and type. METHODS: This was a retrospective analysis of the National Cancer Database (NCDB) that included patients ≥40 years diagnosed with ALL between 2004 and 2016. RESULTS: A total of 14 593 patients were included in this study. Univariate OS was greatest at low volume (LV) and community programs (CPs) and the least at high volume (HV) and academic programs (AP). This difference was lost after multivariable Cox proportional hazards model analysis, which found no difference in survival by facility volume or type, however, survival was significantly influenced by age, race, Hispanic ethnicity, insurance, and residence location (p < 0.05). Patients treated at HV and APs compared to LV and CP received more anti-neoplastic directed therapy. CONCLUSION: Our results suggest treatment facility volume and type do not impact older adult ALL patient (≥40 years) survival, however confounding sociodemographic differences do impact survival outcomes, despite more aggressive and novel treatment approaches provided at HV and APs.

Top Ten Tips Palliative Care Clinicians Should Know About Caring for Patients with Myeloproliferative Neoplasms.

Myeloproliferative neoplasms (MPNs) are a group of rare chronic progressive blood cancers that vary widely in clinical presentation, yet all patients have a risk of disease progression and thrombotic complications. Diseases include primary myelofibrosis, polycythemia vera, and essential thrombocythemia. With current treatment approaches, most patients live a prolonged life, but many experience a complex of symptoms that negatively influence their functional status and quality of life. Although significant advances have been made in preventing arterial and venous complications while mitigating inflammatory processes, comprehensive palliative care can help address unmet complex physical and psychosocial needs on a long-term basis. This article, created by a multidisciplinary group of providers, offers an overview of MPNs so palliative care clinicians can better support patients with these hematologic cancers.

Influence of Income, Education, and Medicaid Expansion on Palliative Care in Acute Myeloid Leukemia Using the National Cancer Database.

Palliative care is integral to symptom management, and we examined its relationship with income, education, and Medicaid expansion in acute myeloid leukemia. This was a retrospective cross-sectional study using the National Cancer Database that included patients with acute myeloid and monocytic leukemias > 18 years of age treated at Commission on Cancer facilities from 2004 to 2016. Univariate and multivariate models were adjusted for demographic variables and facility characteristics. There were 124,988 patients, but only 106,495 had palliative care data, and of this 4111 (3%) received palliative care. The most educated had the highest odds of receiving palliative care (odds ratio, OR 1.23, 95% CI 1.08-1.41; P = 0.002), but the highest income bracket (≥ $63,333) had the lowest odds (OR 0.82, 95% CI 0.72-0.93; P = 0.003). Residence in states with Medicaid expansion (January 2014 onward) had greater palliative care utilization. Palliative care use was associated with higher education but underutilized with higher incomes. Increased access with Medicaid expansion suggests the importance of public insurance.

Hospital facility characteristics and socioeconomic factors on outcomes and treatment in patients with multiple myeloma: National Cancer Database analysis.

Previous studies have shown that socioeconomic factors play an important role in multiple myeloma (MM) health outcomes. We postulated that the type of treatment facilities and their volume of cases also affect overall survival, utilization of various therapies including palliative care services in newly diagnosed MM. Using the National Cancer Database (NCDB), we analyzed 174,551 newly diagnosed MM participants from across the country. We found that at high volume facility centers (over 90th percentile of new patient volume from 2004 to 2016), the median overall survival (OS) was 62.3 months versus 35.3 months at lower volume facilities (p <0.001). Similarly, high volume academic cancer centers had an improved median OS of 66.4 months (65.3-67.4 CI) versus 39.2 months (37.9-40.4 months CI) in lower volume academic centers (p <0.001). The odds of utilizing chemotherapy, immunotherapy, and autologous transplants were higher in academic cancer centers compared to community cancer centers, after adjusting for demographic and socioeconomic factors (OR 1.10, 1.23, and 2.06 respectively, all with p<0.001). There was significantly decreased odds of receiving palliative care (OR 0.89, 95% CI 0.85-0.93) in high volume facilities compared to low volume. Palliative care services were more frequently utilized at integrated network cancers and comprehensive community cancer centers compared to community cancer centers, with similar odds of receiving palliative care between community and academic facility types. Our results likely reflect increased provider experience and resources in higher volume and academic facilities. This highlights the need to integrate resources and improve access to community programs.

Rational design of a trimeric APRIL-based CAR-binding domain enables efficient targeting of multiple myeloma.

Chimeric antigen receptor (CAR) T cells (CARTs) have shown tremendous potential for the treatment of certain B-cell malignancies, including patients with relapsed/refractory multiple myeloma (MM). Targeting the B-cell maturation antigen (BCMA) has produced the most promising results for CART therapy of MM to date, but not all remissions are sustained. Emergence of BCMA escape variants has been reported under the selective pressure of monospecific anti-BCMA CART treatment. Thus, there is a clinical need for continuous improvement of CART therapies for MM. Here, we show that a novel trimeric APRIL (a proliferation-inducing ligand)-based CAR efficiently targets both BCMA+ and BCMA- MM. Modeled after the natural ligand-receptor pair, APRIL-based CARs allow for bispecific targeting of the MM-associated antigens BCMA and transmembrane activator and CAML interactor (TACI). However, natural ligands as CAR antigen-binding domains may require further engineering to promote optimal binding and multimerization to adequately trigger T-cell activation. We found that using a trimeric rather than a monomeric APRIL format as the antigen-binding domain enhanced binding to BCMA and TACI and CART activity against MM in vitro and in vivo. Dual-specific, trimeric APRIL-based CAR are a promising therapeutic approach for MM with potential for preventing and treating BCMA escape.
