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.
Int J Radiat Oncol Biol Phys
January 2025
Providence Swedish Cancer Institute, Seattle, Washington.
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.
Breast cancer outcomes after skin- and nipple-sparing mastectomy in BRCA pathogenic mutation carriers versus non-BRCA carriers.

Unlabelled: Our previous study on BRCA breast cancer carriers disclosed a high local recurrence (LR) rate in patients who underwent skin sparing (SSM) or nipple sparing mastectomy (NSM) without postoperative radiation therapy (RT), compared to breast conservation surgery or mastectomy with RT. The current study compares the LR rates in BRCA versus non BRCA carriers after SSM/NSM in relation the receipt of RT.
Methods: The study was approved by the institutional ethics committee.
Randomized Evaluation of the PET-Adjusted IMRT for NSCLC Trial (REPAINT).
Int J Radiat Oncol Biol Phys
January 2025
Montefiore Einstein Comprehensive Cancer Center, Bronx, NY.
Background: Standard radiotherapy (RT) for locally advanced NSCLC (LA-NSCLC) employs a uniform dose of approximately 60 Gy. Recent trials demonstrated that radiotherapy dose escalation may not improve outcomes and may cause added toxicity. XXX previously performed a single-arm trial testing a personalized, risk-adapted, and de-intensified RT strategy.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

Clinical risk prediction models are ubiquitous in many surgical domains. The traditional approach to develop these models involves the use of regression analysis. Machine learning algorithms are gaining in popularity as an alternative approach for prediction and classification problems.
