Head and neck paragangliomas: Recent advances in translational and clinical research and guidelines for patient care.

Head and neck paragangliomas (HNPGLs), rare neuroendocrine tumors that mainly arise from parasympathetic ganglia along the cranial nerves, are challenging due to anatomic origin, tendency to aggressive neurovascular and skull base infiltration, unpredictable metastatic potential, radio-chemoresistance, and risk of multiplicity. Symptoms range from mild to life threatening depending on location/size, but rarely relate to catecholamine excess. Risk factors include female sex and pathogenic germline variants in genes affecting hypoxia signaling (foremost succinate dehydrogenase genes).

Identification of Succinate Dehydrogenase Gene Variant Carriers by Blood Biomarkers.

Background: Carriers of germline pathogenic variants (PVs) in succinate dehydrogenase genes () are at risk of developing tumors, including paragangliomas, gastrointestinal stromal tumors, and renal cell carcinomas. Early tumor detection is paramount for improved clinical outcome. Blood-based biomarkers could aid in identifying individuals with PVs early and provide functional evidence in patients with variants of unknown significance.

Steroidomics-Based Screening for Primary Aldosteronism: Impact of antihypertensive Drugs.

Background: Diagnosis of primary aldosteronism (PA) is complicated by the need to withdraw antihypertensive medications that interfere with test results, particularly renin. This study examined whether machine learning-based steroid-probability scores offer a renin measurement-independent approach for testing less prone to interference than the aldosterone-to-renin ratio (ARR).

Methods: This prospective multicenter cohort study involved the use of plasma steroidomics and the ARR in 839 patients tested for PA, including 190 with and 578 without PA (71 indeterminate).

Quality of Life in Patients Undergoing Emergency Surgery for Complex Colorectal Cancer: Protocol and Piloting of the Surgical Utilization and Recovery Patterns for Advanced Stage Colorectal Cancer Study.

Globally, cancer is the leading cause of mortality, with colorectal neoplasia ranking third in terms of incidence and mortality worldwide. Patients face disease- and treatment-specific impacts, which can significantly influence their quality of life (QoL). Aim: This study aimed to propose a protocol to measure in-hospital and long-term QoL in patients with complicated colorectal cancer (CRC).
