Evolutionary Overview and Future Perspectives: ESR1 Mutations, Liquid Biopsy, and Artificial Intelligence for a New Era of Personalized Medicine in ER+ Breast Cancer.

ESR1 gene mutations represent one of the main mechanisms of acquired resistance to endocrine therapy (ET) in estrogen receptor-positive (ER+) breast cancer. The introduction of liquid biopsy as a minimally invasive technique for analyzing circulating tumor DNA (ctDNA) has opened new avenues for real-time mutation monitoring and personalized treatment strategies. This review explores the clinical relevance of ESR1 mutations in endocrine resistance, the potential of liquid biopsy for early detection and monitoring, and the integration of advanced sequencing technologies and artificial intelligence to improve diagnostic accuracy.

Early taxane exposure and neurotoxicity in breast cancer patients.

Introduction: Breast cancer is the most diagnosed tumor and a leading cause of cancer death in women worldwide. Taxanes are the most used chemotherapeutic agents and are strictly connected to neurotoxicity. Taxane-induced neuropathy (TIN) significantly impacts patients' quality of life (QOL).

Mismatch Repair system protein deficiency as a resistance factor for locally advanced rectal adenocarcinoma patients receiving neoadjuvant chemo-radiotherapy.

Background: Available data on Mismatch Repair system (MMR) deficiency are conflicting and derived from small studies. Our study aimed to evaluate the therapeutic implications of MMR status in patients with locally advanced rectal cancer (LARC).

Methods: We retrospectively collected data from 318 patients affected by LARC treated in Italy at the Medical Oncology Units of the University Hospital of Cagliari, Istituto Nazionale dei Tumori Milan, and AOU Ospedali Riuniti Ancona.

New Horizons in Metastatic Colorectal Cancer: Prognostic Role of CD44 Expression.

Background: The transmembrane glycoprotein CD44, the major hyaluronan (HA) receptor, has been proven to regulate cell growth, survival, differentiation, and migration. It is therefore widely considered to be involved in carcinogenesis. Its role as a new therapeutic target in solid tumors is under evaluation in clinical trials.

Determination of salivary cortisol to assess time-related changes of the adrenal response to stress in critically ill patients.

Background: The value of salivary cortisol measurement to study stress-related adrenal response is controversial. The study aim was to assess the role of salivary cortisol measurement to detect time-related changes of adrenal response in critically ill patients.

Patients And Methods: Patients with organ failure, sepsis or trauma were prospectively recruited in the Emergency Department.

Increased osteoprotegerin levels in Cushing's syndrome are associated with an adverse cardiovascular risk profile.

Context: Patients with Cushing's syndrome (CS) have a mortality rate four times higher than age- and sex-matched subjects, mainly due to cardiovascular events. Serum osteoprotegerin (OPG) levels are increased in patients with cardiovascular disease and/or excess bone resorption.

Objective: The aim of the study was to assess serum OPG and soluble receptor activator of nuclear factor-kappaB ligand (sRANKL) levels in CS and their possible relationship with coronary risk profile.
