Adjuvant endocrine therapy for early breast cancer significantly reduces recurrence but increases bone fragility. Given limited data on denosumab (60 mg every 6 months) in premenopausal patients receiving endocrine therapy for early breast cancer, we conducted a retrospective real-world study at the Gemelli Hospital (September 2018-January 2025). A descriptive analysis was performed.

Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) plus endocrine therapy (ET) are the mainstay of treatment for hormone receptor positive, HER2 negative (HR + /HER2-) metastatic breast cancer (MBC). However, disease progression is inevitable and unveiling resistance mechanisms is crucial to guide post-CDK4/6i therapeutic strategies. In this study, we retrospectively analyzed a real-world, multi-institutional cohort of patients with HR + /HER2- MBC characterized by circulating tumor DNA (ctDNA) through next-generation sequencing (NGS) before starting second-line treatment.

Over the past decade, liquid biopsy (LB) has emerged as a key tool in oncology. Its utility in non-invasive sampling and real-time monitoring has made it a cornerstone in precision medicine. Since 2020, publications on LB in solid tumors have doubled, underscoring its pivotal role in advancing cancer care.

Circulating tumor cells (CTCs) have emerged as a key prognostic biomarker for breast cancer, with their role becoming more pronounced in metastatic cases. In metastatic breast cancer, having five or more CTCs per 7.5 mL of blood is linked to poorer survival and more aggressive disease, marking it as stage IV.

Purpose: To investigate metabolic parameters from baseline F-FDG PET/CT as predictors of pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) and disease recurrence in locally advanced breast cancer (LABC) patients.

Materials And Methods: From 142 LABC in 137 patients (bilateral-synchronous BC: 5/137), the following parameters from baseline (pre-treatment) F-FDG PET/CT were retrospectively analyzed, along with clinic-histological data: primary tumor activity (SUVmax, SUVmean, SUVpeak, tumor-to-liver ratio-TLR-, MTV, TLG); lymphoid organs activity (spleen and bone marrow SUVmax and SUVmean, spleen-to-liver ratio-SLR-, bone marrow-to-liver ratio-BLR); and PET-positive lymph-nodes' number. Predictors of pCR and recurrence-free survival (RFS) were assessed by univariable logistic regression and Cox regression (significant or suggestive association: p < 0.

Hormone receptor-positive/HER2-negative breast cancer (BC) is the most common subtype of BC and typically occurs as an early, operable disease. In patients receiving neoadjuvant chemotherapy (NACT), pathological complete response (pCR) is rare and multiple efforts have been made to predict disease recurrence. We developed a framework to predict pCR using clinicopathological characteristics widely available at diagnosis.

Article Synopsis
  • Advancements in antiemetic drugs have improved the management of chemotherapy-induced nausea and vomiting (CINV), but about 30% of adult patients still experience persistent symptoms, leading to complications.
  • Supportive care interventions, including physical exercise and nutritional counseling, have proven effective in reducing CINV severity, while psychological interventions and acupuncture have also shown promise.
  • The review aims to update current guidelines for preventing and treating CINV and to explore various non-drug interventions available for cancer patients.

Article Synopsis
  • Liquid biopsy is a new way to help doctors find and track breast cancer by looking for special markers in the blood.
  • Instead of just focusing on one type of marker, researchers are now combining different markers to get a better understanding of the cancer.
  • This method could lead to better detection, tracking, and treatment of breast cancer and other types of cancer, but improvements in technology and teamwork are needed to make it really effective.

Article Synopsis
  • Recent improvements in breast cancer survival rates are not reflected for gender minorities, as they are often excluded from clinical trials.
  • A review of 51 phase III clinical trials showed that only 35.3% allowed men to enroll, and none reported on transgender or gender-diverse participants.
  • The study calls for more inclusive trial criteria to better represent gender minorities, highlighting a significant underrepresentation and varying enrollment rates across different drug classes.

Targeted therapy (TT) has revolutionized cancer treatment, successfully applied in various settings. Adjuvant TT in resected early-stage gastrointestinal stromal tumors (GIST), melanoma, non-small cell lung cancer (NSCLC), and breast cancer has led to practice-changing achievements. In particular, standard treatments include BRAF inhibitors for melanoma, osimertinib for NSCLC, hormone therapy or HER2 TT for breast cancer, and imatinib for GIST.

The human epidermal growth factor receptor 2 (HER2) plays a central role in breast cancer (BC). Therefore, it is critical to develop a method that can capture its spatial and temporal heterogeneity. Nowadays, therapeutic decisions for BC patients relies on evaluation of HER2 status from tissue biopsies using immunohistochemistry and hybridization.

Background: In early breast cancer (BC) the impact of denosumab on survival outcomes is still unclear. We undertook a systematic review and meta-analysis to assess efficacy and safety of adjuvant denosumab in addition to standard anticancer therapy.

Methods: PubMed, CENTRAL, Scopus, Embase, and oncological meetings websites were screened to identify potentially eligible randomized controlled trials (RCTs).

Cancer treatment-related adverse events (AEs) are sometimes associated with outcomes for cancer patients, especially with the newest therapies such as target therapy and immunotherapy. A few years ago, the first-line therapy for hormone-receptor-positive metastatic breast cancer (mBC) patients has been deeply changed by the introduction of cyclin-dependent kinase (CDK) 4/6 inhibitors, and now, we are improving our knowledge about their AEs and significance in clinical practice. Here, we report our experience with two cases of vitiligo-like lesions that occur early during treatment with ribociclib.

Article Synopsis
  • The liver is a common site for metastasis in metastatic breast cancer (MBC), affecting 5-12% of cases, and liver metastasectomy (LM) may be a treatment option for certain patients.
  • A study analyzed 49 MBC patients who underwent LM over 25 years, focusing on their overall survival (OS) and disease-free interval (DFI) post-surgery.
  • Results showed a median OS of 67 months and DFI of 15 months, with negative resection margins being a key factor positively influencing survival outcomes.
