Cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i): Mechanisms of resistance and where to find them.

CDK4/6 inhibitors (CDK4/6i) have significantly impacted on the treatment of HR + HER2 negative (HER2-) metastatic breast cancer (BC) when combined with endocrine therapy. Nonetheless, despite significant research efforts, the mechanisms of de novo and acquired resistance to CDK4/6i have not yet been fully elucidated, highlighting the need for a deeper understanding of these process. Additionally, the importance of dissecting CDK4/6i resistance from endocrine resistance for personalized treatment is increasingly recognized.

Clinico-pathological predictors of radiologic complete response to first-line anti-HER2 therapy in metastatic breast cancer.

This study aimed to identify the clinico-pathological variables predictive of radiologic complete response (rCR) to first-line anti-HER2 therapy in patients with HER2-positive metastatic breast cancer. Patients were selected from the database of the GIM14 study and classified according to the best radiologic response obtained to first-line anti-HER2 therapy and upon time-to-treatment-discontinuation (TTD). A total of 545 patients were included in the analysis.

Is ctDNA ready to outpace imaging in monitoring early and advanced breast cancer?

Introduction: Circulating tumor DNA (ctDNA) and radiological imaging are increasingly recognized as crucial elements in breast cancer management. While radiology remains the cornerstone for screening and monitoring, ctDNA holds distinctive advantages in anticipating diagnosis, recurrence, or progression, providing concurrent biological insights complementary to imaging results.

Areas Covered: This review delves into the current evidence on the synergistic relationship between ctDNA and imaging in breast cancer.

Managing sexual health challenges in breast cancer survivors: A comprehensive review.

The significant advancements in breast cancer management have led to an increase in the prevalence of breast cancer survivors. Despite their efficacy, these treatments can cause a variable range of side effects, significantly deteriorating the patients' quality of life. Sexual dysfunction, and in particular the genitourinary syndrome of menopause, represent one of the major causes of quality-of-life impairment among breast cancer patients, potentially affecting treatment adherence and compliance.

Nutritional Management of Oncological Symptoms: A Comprehensive Review.

Throughout their experience of illness and during the course of treatment, a substantial proportion of cancer patients are prone to develop nutritional and/or metabolic disturbances. Additionally, cancer patients often encounter long-term side effects from therapies, which may lead to impaired digestion, nutrient absorption or bowel motility. Therefore, the preservation and maintenance of an optimal and balanced nutritional status are pivotal to achieving a better prognosis, increasing the tolerance and adherence to cancer therapies and improving the overall quality of life.
