Long-Term Outcomes of Radiation Monotherapy Versus Combined Radiation Monotherapy + Hormone Therapy in Low-Risk Early-Stage Breast Cancer Patients 70 Years or Older After Breast-Conserving Surgery.

Purpose: Standard therapy for breast cancer after breast-conserving surgery is radiation therapy (RT) plus hormone therapy (HT). For patients with a low-risk of recurrence, there is an interest in deescalating therapy.

Methods And Materials: A retrospective study was carried out for patients treated at the Swedish Cancer Institute from 2000 to 2015, aged 70 years or older, with pT1N0 or pT1NX estrogen receptor-positive and ERBB2-negative unifocal breast cancer without positive surgical margins, high nuclear grade, or lymphovascular invasion.

Individualized Prediction for Risk of Recurrence in Stage I/II Melanoma Patients With Negative Sentinel Lymph Node.

Background: Despite the favorable prognosis of AJCC stage I/II melanoma patients, up to 20%-30% will develop metastases. Our objective is to predict long-term risk (probability) of recurrence in early-stage melanoma patients.

Methods: A Risk Score to predict long-term recurrence was developed using Cox regression based on 2668 patients.

Are Nomograms Useful for Predicting Sentinel Lymph Node Status in Melanoma Patients?

Background And Objectives: Clinical nomograms have been developed to predict sentinel lymph node (SLN) status in early-stage melanoma patients, but the clinical utility of these tools remains debatable. We created and validated a nomogram using data from a randomized clinical trial and assessed its accuracy against the well-validated Melanoma Institute Australia (MIA) nomogram.

Methods: We developed our model to predict SLN status using logistic regression on clinicopathological patient data from the Multicenter Selective Lymphadenectomy Trial-I.

Widespread Adoption of Precision Anticancer Therapies After Implementation of Pathologist-Directed Comprehensive Genomic Profiling Across a Large US Health System.

Purpose: Precision therapies and immunotherapies have revolutionized cancer care, with novel genomic biomarker-associated therapies being introduced into clinical practice rapidly, resulting in notable gains in patient survival. Despite this, there is significant variability in the utilization of tumor molecular profiling that spans the timing of test ordering, comprehensiveness of gene panels, and clinical decision support through therapy and trial recommendations.

Methods: To standardize testing, we designed a pathologist-directed test ordering system at the time of diagnosis using a 523-gene DNA/RNA hybrid comprehensive genomic profiling (CGP) panel and extensive clinical decision support tools.

The Intersecting Effects of Lifetime Experiences of Homelessness and Incarceration on Cognitive Aging and Dementia Risk Factors in the United States.

Background And Objectives: Alzheimer's disease and related dementias (ADRD) remain a pressing concern in the US, which also has one of the highest incarceration rates worldwide. Existing research has analyzed dementia risk and care among currently incarcerated and homeless populations; this paper fills a gap by examining later-life cognitive disparities facing formerly incarcerated and/or homeless individuals.

Research Design And Methods: Using Health and Retirement Study data (HRS; 1998-2018), we tested whether formerly homeless and/or incarcerated people had earlier onset of cognitive decline, and whether they were more likely to have modifiable risk factors for ADRD than those without such experiences.
