Purpose/objective(s): While definitive chemoradiation (CRT) with 5-FU/MMC remains the standard of care for localized anal cancer, treatment is associated with significant acute and late toxicity. Proton radiation therapy (RT) may potentially reduce such toxicity. Here, we assess the long-term outcomes of anal cancer patients treated with CRT using proton RT in two prospective pilot studies.

Reducing radiation-induced hypothyroidism by modified delineation of cervical lymphatic drainage area for nasopharyngeal carcinoma treated by intensity-modulated radiation Therapy: 3 years' experience.

Radiother Oncol

January 2025

NHC Key Laboratory of Personalized Diagnosis and Treatment of Nasopharyngeal Carcinoma, Jiangxi Cancer Hospital, The Second Affiliated Hospital of Nanchang Medical College, Nanchang 330029 China; Department of Radiation Oncology, Jiangxi Clinical Research Center for Cancer, Jiangxi Cancer Hospital, The Second Affiliated Hospital of Nanchang Medical College, Nanchang 330029 China. Electronic address:

Background And Purpose: Radiation-induced hypothyroidism (RIHT) is a late complication of intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC). We evaluated thyroid protection in NPC patients receiving IMRT using modified delineation (MD) of cervical lymphatic drainage areas, sparing the common carotid artery within the clinical target volume (CTV), to assess its impact on thyroid function and survival outcomes.

Materials And Methods: This retrospective cohort study included patients without metastatic lymph nodes at levels III and IV who received neck irradiation.

Aims: Unresectable cutaneous squamous cell cancer of the head and neck (HNcSCC) poses treatment challenges in elderly and comorbid patients. Radiation therapy (RT) is often employed for locoregional control. This study aimed to determine progression-free survival (PFS) and overall survival (OS) outcomes achieved with upfront RT in unresectable HNcSCC.

Purpose: This systematic review aimed to assess the updated literature for the prevention of salivary gland hypofunction and xerostomia induced by non-surgical cancer therapies.

Methods: Electronic databases of MEDLINE/PubMed, EMBASE, and Cochrane Library were searched for randomized controlled trials (RCT) that investigated interventions to prevent salivary gland hypofunction and/or xerostomia. Literature search began from the 2010 systematic review publications from the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) up to February 2024.

Background: In patients with breast cancer, prone radiation therapy (RT) has been shown to reduce heart and lung dose. Though prone positioning is routinely used for whole breast RT, its use when treating the regional lymph nodes (RLNs) is not widespread.

Methods: In this phase I-II trial for stage IB-IIA breast cancer treated with lumpectomy or mastectomy, patients received 40.
