Transfer Learning-Based Autosegmentation of Primary Tumor Volumes of Glioblastomas Using Preoperative MRI for Radiotherapy Treatment.

Objectives: Glioblastoma is the most common primary malignant brain tumor in adults and can be treated with radiation therapy. However, tumor target contouring for head radiation therapy is labor-intensive and highly dependent on the experience of the radiation oncologist. Recently, autosegmentation of the tumor target has been playing an increasingly important role in the development of radiotherapy plans.

Radiation-induced glioblastoma with rhabdoid characteristics following treatment for medulloblastoma: A case report and review of the literature.

Glioblastoma multiforme (GBM) is a high-grade glioma that may develop from several other central nervous system tumors after radiation therapy. We herein report a case of GBM occurring 8 years after radiation therapy for medulloblastoma. The secondary tumor was histologically distinctly different from the primary tumor.

Vitamin D improves immune function in immunosuppressant mice induced by glucocorticoid.

Vitamin D is an essential fat-soluble vitamin with multiple functions. Vitamin D receptor has been shown to be expressed in several types of immune cells suggesting vitamin D may have immune regulatory roles. Vitamin D insufficiency has been suggested to increase the risk of autoimmune diseases.

Successful treatment of recurrent Kimura's disease with radiotherapy: a case report.

Kimura's disease is a rare, chronic inflammatory disorder affecting the skin and subcutaneous tissue, predominantly in the head and neck region. It is benign but may be recurrent and difficult to eradicate. A case of recurrent Kimura disease in a 53-year-old man was reported.
