Importance: Young adults aged 18 to 39 years represent the minority of breast cancer diagnoses but are particularly vulnerable to financial hardship. Factors contributing to sustained financial hardship are unknown.

Objectives: To identify financial hardship patterns over time and characterize factors associated with discrete trajectories; it was hypothesized that treatment-related arm morbidity, a key source of expense, would be associated with long-term financial difficulty.

Article Synopsis
  • Many young women diagnosed with breast cancer (BC) are interested in breastfeeding after treatment, but there's limited information on their experiences.
  • In a study of 143 women diagnosed with BC, around 55% attempted breastfeeding, with satisfaction rates high despite challenges such as mastectomies and low milk production.
  • There's a need for more specific resources and support for BC survivors who want to breastfeed, as many women reported receiving helpful information only from their oncology teams or online.*

Article Synopsis
  • - The study examined the cardiovascular disease (CVD) risk linked to cancer treatments in young women (≤40 years) with breast cancer, focusing on data from 372 survivors over five years.
  • - Findings revealed that radiation treatment, especially left-sided radiation, was associated with a significant increase in excess heart age, while systemic cancer treatments showed no correlation with heart age changes.
  • - The authors suggest that CVD risk assessment tools should integrate cancer treatment history to better identify young breast cancer survivors at high risk for cardiovascular issues.

AbstractThere is societal consensus that cancer clinical trial participation is unjust because some sociodemographic groups have been systematically underrepresented. Despite this, neither a definition nor an ethical explication for the justice norm of equity has been clearly articulated in this setting, leading to confusion over its application and goals. Herein we define equity as acknowledging sociodemographic circumstances and apportioning resource and opportunity allocation to eliminate disparities in outcomes, and we explore the issues and tensions this norm generates through practical examples.

Purpose: Erb-B2 receptor tyrosine kinase 2 ()-positive breast cancer (BC) is particularly common in young women. Genomic features of -positive tumors before and after chemotherapy and trastuzumab (chemo + H) have not been described in young women and are important for guiding study of therapeutic resistance in this population.

Methods: From a large prospective cohort of women age 40 years or younger with BC, we identified patients with -positive BC and tumor tissue available before and after chemo + H.

Extended adjuvant endocrine therapy (eET) improves outcomes in breast cancer survivors. Most studies however have been limited to postmenopausal women, and optimal eET for young survivors is uncertain. We report eET use among participants in the Young Women's Breast Cancer Study (YWS), a multicenter prospective cohort of women age ≤40 newly diagnosed with breast cancer enrolled between 2006-2016.

Purpose: Antibiotic exposure before immune checkpoint inhibitor (ICI) treatment can negatively affect outcomes through alteration in the gut microbiome, but large-scale evaluations are lacking. We performed a population-level retrospective cohort study to evaluate the impact of antibiotic exposure before starting ICI on overall survival (OS).

Patient And Methods: Patients with cancer, age 65 years or older, who initiated treatment with ICIs between June 2012 and October 2018 in Ontario, Canada, were identified using systemic therapy administration data.

Article Synopsis
  • The study aimed to determine the best timing for exercise therapy to enhance cardiorespiratory fitness (CRF) in women with breast cancer undergoing chemotherapy.
  • The research involved a randomized trial with 158 participants divided into groups receiving different exercise regimens (during, after, or both) compared to usual care.
  • Results showed no significant difference in CRF improvement between the concurrent and sequential exercise groups, but continuous exercise over 32 weeks showed notable benefits, suggesting more research is needed.

Background: Patients taking adjuvant endocrine therapy (AET) after breast cancer face adherence challenges and symptom-related distress. We conducted a randomized trial to evaluate the feasibility, acceptability, and preliminary efficacy of a telehealth intervention (Symptom-Targeted Randomized Intervention for Distress and Adherence to Adjuvant Endocrine Therapy [STRIDE]) for patients taking AET.

Methods: From October 2019 to June 2021, 100 patients reporting difficulty with AET were randomly assigned to either STRIDE or a medication monitoring (MedMon) control group.

As the prognosis for multiple myeloma (MM) has significantly improved and patients remain on therapy longer, there is a need for supportive care interventions to optimize patient quality of life (QOL) and functional status over the course of cancer treatment. MM is characterized by a significant symptom burden and a relatively lower QOL compared to other cancers. This review evaluates the role of healthy lifestyle behaviors in improving both the physical functioning and psychological well-being of the MM population.
