Exploring RAS mutation incidence and temporal heterogeneity in metastatic colorectal cancer patients - a single-institution experience utilising circulating tumour DNA.

Introduction: Colorectal cancer (CRC) remains a significant global health challenge, ranking among the leading causes of neoplastic mortality. Despite transformative therapeutic advances, a considerable proportion of patients are diagnosed with metastatic disease, and 15-30% of those initially presenting with early-stage CRC eventually experience recurrence. Comprehensive molecular testing, especially the evaluation of microsatellite instability and mutations in KRAS/NRAS or BRAF genes, is essential upon diagnosis of stage IV disease, guiding treatment decisions.

Exploring a Rarity: Incidence of and Therapeutic Approaches for Neurological Complications and Hypophysitis in Cancer Patients on Immune Checkpoint Inhibitors-A Single-Center Study.

Immune checkpoint inhibitors, such as anti-PD-1 and anti-CTLA-4 inhibitors, have become the standard of care for many cancer types. However, they induce immune-related adverse events (irAEs), including neurotoxicity and hypophysitis. The incidence and outcomes of neurotoxicity and hypophysitis in patients treated with immune checkpoint inhibitors are not well established.

Gender identity disputed in the court of justice: a story of female to male sexual transformation in the hellenistic period, described by Diodorus Siculus.

Cases of sexual reassignment in Greco-Roman antiquity, presenting as a pubertal female to male gender transformation, are described in the "classical"literature. Textual evidence concerning a case of androgynism, garnered by Diodorus Siculus, among other similar accounts, as an odd story of gender dispute in a court of justice, is provided in the present study. A medical interpretation of the data pertaining to this case has been attempted and is herein reported.
