Article Synopsis
- * The case involves a patient who had a fistula-related perianal squamous cell carcinoma and was undergoing maintenance therapy for Crohn's disease.
- * The patient successfully completed standard chemoradiotherapy with intensity-modulated radiotherapy, experienced no severe toxicity, and achieved complete remission, suggesting that this treatment method could be viable for similar patients when their Crohn's disease is well-managed.
Purpose: We investigated the prevalence of hypothyroidism (HT) in patients with breast cancer who received radiation therapy to the supraclavicular (SC) field to evaluate the effect of radiation on thyroid.
Methods: Between April 2007 and May 2016, consecutive patients with invasive breast cancer who received SC radiation were recruited. Thyroid-stimulating hormone (TSH) and free thyroxine (fT4) were measured between April and August 2016.
Purpose: When treating large metastatic brain tumors with stereotactic radiotherapy (SRT), high dose conformity to target is difficult to achieve. Employing a modified planning target volume (mPTV) instead of the original PTV may be one way to improve the dose distribution in linear accelerator-based SRT using a dynamic conformal technique. In this study, we quantitatively analyzed the impact of a mPTV on dose distribution.
