Target volume delineation of the neck for radiotherapy in nasopharyngeal carcinoma: CSTRO, CACA, CSCO, HNCIG, ESTRO, and ASTRO guidelines and contouring atlas.

The Chinese Society for Therapeutic Radiology Oncology, the Chinese Anti-Cancer Association, the Chinese Society of Clinical Oncology, the Head and Neck Cancer International Group, the European Society for Radiotherapy and Oncology, and the American Society for Radiation Oncology collaboratively developed evidence-based guidelines and a comprehensive contouring atlas for neck target volume delineation in nasopharyngeal carcinoma. These guidelines address five key challenges in modern radiotherapy practice: margin design of clinical target volume; nodal target volume delineation after induction chemotherapy; delineation of equivocal nodes evident on imaging; low-risk clinical target volume delineation based on regional stepwise extension patterns; and modifications for anatomical boundaries of lymphatic areas. Developed through a rigorous systematic review and expert appraisal process by a panel of 50 international, multidisciplinary members from 17 countries and regions, these guidelines incorporate the latest advances in nasopharyngeal carcinoma diagnosis and treatment.

Primary target volume delineation for radiotherapy in nasopharyngeal carcinoma: CSTRO, CACA, CSCO, HNCIG, ESTRO, and ASTRO guidelines and contouring atlas.

The Chinese Society for Therapeutic Radiology Oncology, the Chinese Anti-Cancer Association, the Chinese Society of Clinical Oncology, Head and Neck Cancer International Group, the European Society for Radiotherapy and Oncology, and the American Society for Radiation Oncology jointly developed evidence-based guidelines and a contouring atlas for primary target volume delineation for radiotherapy in nasopharyngeal carcinoma. The guidelines systematically address three crucial challenges: margin design of clinical target volumes; target volume delineation after induction chemotherapy; and low-risk clinical target volume delineation based on local stepwise extension patterns. Based on a comprehensive systematic review and critical appraisal by an international multidisciplinary panel of 50 nasopharyngeal carcinoma specialists from 17 countries and regions, these guidelines are in keeping with advances in nasopharyngeal carcinoma diagnosis and treatment, embodying contemporary treatment concepts, and elaborating on the differences in practice.

Cardiac Troponin Screening and Clinical Outcomes in Patients Receiving Immunotherapy.

Background: Immune checkpoint inhibitors (ICIs) are associated with cardiotoxicities such as myocarditis. However, data on the implementation and outcomes of cardiac biomarker screening remain limited.

Objectives: The aim of this study was to examine the impact of cardiac troponin I (cTnI) surveillance integrated with symptom-based triaging in patients receiving immunotherapy.

Update: Immunotherapeutic Strategies in HPV-Associated Head and Neck Squamous Cell Carcinoma.

The incidence of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) has increased substantially over the past three decades, and since 2017, it has been recognized in the AJCC staging system as distinct from its HPV-negative counterpart. The underlying mechanisms of HPV-associated carcinogenesis, tumor microenvironment, and host immune response represent opportunities for therapeutic development. While anti-PD-1 immunotherapy is now part of standard treatment for recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) in general, there are no established immunotherapeutic strategies specifically for HPV-related HNSCC.
