Special Issue Information

Dear Colleagues,

At present, significant advancements have been made in the field of breast cancer research, leading to improved detection, diagnosis, and treatment options. This Special Issue aims to gather cutting-edge research and innovative developments in breast cancer to further enhance our understanding and management of this complex disease.

The topics of interest for publication include but are not limited to the following:

  • Early detection and diagnosis techniques;
  • Novel therapeutic strategies and drug development;
  • Personalized medicine and targeted therapies;
  • Survivorship and quality of life issues for breast cancer patients;
  • Role of artificial intelligence and machine learning in breast cancer research;
  • Immunotherapy and its applications in breast cancer treatment.

Background: Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors are the standard of care for hormone receptor (HR)+/human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer in combination with endocrine therapy. However, the real-world efficacy and safety of standard versus reduced doses in elderly patients remain unclear. This study aims to compare the clinical outcomes of standard versus reduced doses of CDK4/6 inhibitors in elderly patients with metastatic breast cancer. Methods: This multicenter retrospective cohort study included 158 patients aged ≥70 years diagnosed with HR+/HER2-negative metastatic breast cancer who received either standard or reduced doses of CDK4/6 inhibitors (Ademaciclib, Ribociclib, Palbociclib) as first-line therapy. Progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated. PFS and OS were estimated using the Kaplan–Meier method, and comparisons between groups were performed using a log-rank test. Results: Of the total population, 108 patients (68.4%) received the standard dose, and 50 patients (31.6%) received a reduced dose. The standard-dose group had significantly longer median PFS compared to the reduced-dose group (21.3 vs. 15.2 months, p = 0.014), while the median OS did not differ significantly (37.2 vs. 37.2 months, p = 0.103). Subgroup analyses revealed no significant differences in PFS or OS between standard and reduced doses for Ademaciclib and Ribociclib, while Palbociclib at standard dose showed superior PFS (21.9 vs. 12.7 months, p = 0.029) and OS (50.5 vs. 28.6 months, p = 0.026). The incidence of Grade 2–4 AEs was higher in the standard-dose group (74.2% vs. 56.8%, p = 0.044). Conclusions: Dose reduction of CDK4/6 inhibitors, particularly Ademaciclib and Ribociclib, is a viable option in elderly patients, maintaining comparable OS outcomes to standard dosing while reducing the risk of adverse events. Palbociclib at standard dose may offer superior outcomes. These findings support personalized dosing strategies to optimize efficacy and tolerability in frail or elderly patients. Full article

Objective: With advancements in treatment, the increasing number of women with breast cancer has led to a growing focus on enhancing their well-being by understanding health-related quality of life (HRQoL). This study aimed to investigate the association between comorbidities and HRQoL in middle-aged and older community-dwelling Korean women with breast cancer. Methods: Data from the Sixth, Seventh, and Eighth Korea National Health and Nutrition Examination Surveys between 2014 and 2020 were used to analyze 12,218 women aged ≥50 years (244 women with breast cancer vs. 11,974 women without breast cancer). HRQoL was assessed using the EQ-5D-3L tool and the EQ-5D index. Associations between comorbidities (arthritis, depression, hypertension, diabetes, and cardiovascular disease) and HRQoL were examined. Results: Among women with breast cancer, arthritis was associated with problems in mobility (OR, 3.24; 95% CI, 1.39–7.53) and pain/discomfort (OR, 7.30; 95% CI, 3.62–14.73). Depression was associated with problems in self-care (OR, 7.02; 95% CI, 1.97–25.01), usual activities (OR, 5.73; 95% CI, 1.52–21.59), pain/discomfort (OR, 5.58; 95% CI, 1.49–20.87), and anxiety/depression (OR, 3.81; 95% CI, 1.14–12.72). Arthritis and depression were also considerably associated with overall HRQoL, as measured by the EQ-5D index. Hypertension, diabetes, and cardiovascular disease were not independently associated with HRQoL. Conclusions: Arthritis and depression were markedly associated with HRQoL in middle-aged and older women in the community who suffer from breast cancer. Public health interventions that focus on managing these comorbidities can enhance the well-being of women with breast cancer. Full article
