Acute myeloid leukemia (AML) often requires allogeneic hematopoietic cell transplantation (alloHCT) for cure, but historically alloHCT has been strikingly underutilized. Reasons for this remain uncertain at the population level. We examined alloHCT utilization over time and explored associations between demographic/healthcare factors and use of alloHCT by age group (AYA 15-39y, adult 40-64y, older adult 65-79y) using a linked dataset merging the Center for International Blood and Marrow Transplant Research, California Cancer Registry, and California Patient Discharge Database.

Article Synopsis
  • Childhood exposure to radioactive iodine from the Chornobyl accident increases the risk of papillary thyroid carcinoma (PTC), particularly in younger individuals.
  • A study of 428 PTC cases found that cervical lymph node metastases (cLNM) were more common in PTC with certain genetic fusions compared to mutations, and this frequency varied significantly by specific gene types.
  • Molecular profiling of the cLNM showed strong genetic concordance with primary PTCs and identified 17 differentially expressed genes, pointing to potential biological mechanisms in PTC metastasis that require further investigation.

Compared with the general population, hematopoietic cell transplantation (HCT) survivors are at elevated risk for developing solid subsequent neoplasms (SNs). The Center for International Blood and Marrow Transplant Research (CIBMTR) is a key resource for quantifying solid SN incidence following HCT, but the completeness of SN ascertainment is uncertain. Within a cohort of 18 450 CIBMTR patients linked to the California Cancer Registry (CCR), we evaluated the completeness of solid SN data reported to the CIBMTR from 1991 to 2018 to understand the implications of using CIBMTR data alone or combined with CCR data to quantify the burden of solid SNs after HCT.

The simultaneous presence of different electrophores provides an interesting playground for responsive materials. Herein, we present the incorporation of a twice-reversibly oxidizable tetrathiafulvalene (TTF) unit into a binucleating ligand, bridging two metal centers in a fully conjugated plane. A two-step synthesis scheme gave the D symmetric Schiff base-like ligand HL in moderate yields from which the corresponding copper(II) [Cu2L], nickel(II) [Ni2L], [Ni2L(py)4] and iron(II) complexes [Fe2L(py)4], [Fe2L(dmap)4] and [Fe2L(bpee)2]·1 Tol could be obtained.

Type II diabetes is associated with cancer risk in the general population but has not been well studied as a risk factor for subsequent malignancies among cancer survivors. We investigated the association between diabetes and subsequent cancer risk among older (66-84 years), 1-year breast cancer survivors within the linked Surveillance Epidemiology and End Results (SEER)-Medicare database using Cox regression analyses to quantify hazard ratios (HR) and corresponding 95% confidence intervals (95% CI). Among 133 324 women, 29.

Background: Population-based survival studies of adult acute myeloid leukemia (AML) have not simultaneously evaluated age at diagnosis, race and ethnicity, sex, calendar period or AML subtypes/subgroups among chemotherapy-treated patients.

Methods: For 28,473 chemotherapy-treated AML patients diagnosed at ages ≥20 years in population-based cancer registry areas of the Surveillance, Epidemiology, and End Results Program (2001-2018, followed through 2019), we evaluated 1-month through 5-year relative survival (RS) and 95% confidence intervals (95% CI) using the actuarial method in the SEER∗Stat Survival Session and overall survival (OS) using multivariable Cox regression to estimate proportional hazard ratios (HR) and 95% CI.

Findings: RS decreased with increasing age (20-39, 40-59, 60-74, 75-84, ≥85 years) at AML diagnosis.

Purpose: Autologous hematopoietic cell transplantation (autoHCT) is associated with survival benefits in multiple myeloma (MM), but utilization remains low and differs by sociodemographic factors. Prior population-based studies have not fully captured autoHCT utilization or examined relationships between sociodemographic factors and autoHCT trends over time.

Patients And Methods: We used a novel data linkage between the California Cancer Registry, Center for International Blood and Marrow Transplant Research, and hospitalizations to capture autoHCT in a population-based MM cohort (n = 29, 109; 1991-2016).

Despite the excellent disease-specific survival associated with low-risk differentiated thyroid cancer (DTC), its diagnosis and management have been linked to patient concerns about cancer recurrence, treatment-related health risks, and mortality. Lack of information regarding long-term health outcomes can perpetuate these concerns. Therefore, we assessed all-cause and cause-specific mortality in a large cohort of individuals diagnosed with low-risk DTC.

Article Synopsis
  • This study evaluates the challenges of tracking outcomes after hematopoietic cell transplantation (HCT) by comparing data from two sources: the Center for International Blood and Marrow Transplant Research (CIBMTR) and the California Cancer Registry (CCR).
  • It finds high agreement in patient vital status (97%+) but significant discrepancies in the cause of death reporting, with CIBMTR reporting more noncancer-related deaths and CCR showing a higher number of cancer-related deaths.
  • The analysis reveals that the CCR provides longer follow-up durations, indicating potential benefits of integrating cancer registry data to improve understanding of patient outcomes post-HCT.

Rationale And Objectives: Over 20% of the Lesbian, Gay, Bisexual, Queer or Questioning, Intersex, Asexual or Ally, and more (LGBTQIA+) community reports experiencing discrimination upon accessing health care, causing many to defer access to care and resulting in poorer outcomes. While members of this community routinely undergo imaging studies, little formal education exists within the field of radiology to review the unique health care needs of this population and the specific relevance to imaging, in addition to actionable methods to promote inclusion.

Materials And Methods: A 1-hour educational conference was held for a cohort of radiology resident physicians at our institution, in which topics including LGBTQIA+ health care disparities, clinical nuances relevant to the field of radiology, and actionable suggestions that both academic and private-practice centers can adopt to foster inclusion were presented.
