BACKGROUND: Gynecomastia is a frequent side effect of antiandrogen therapy for prostate cancer and may compromise quality of life. Although it has been successfully treated with radiotherapy (RT) for decades, the priority of RT as a preferred treatment option has...
The Small Animal Radiation Research Platform (SARRP) is a novel isocentric irradiation system that enables state-of-the-art image-guided radiotherapy research to be performed with animal models. This paper reports the results obtained from investigations assessing the...
BACKGROUND: A multidisciplinary nonmelanoma skin cancer (NMSC) clinic is held weekly at our center, where all new patients are jointly assessed by dermatology/dermatopathology, radiation oncology, and plastic surgery. A new patient database was established in 2004....
PURPOSE: To report an exceptionally large conjunctival-corneal intraepithelial neoplasia (CCIN) (Bowen disease), for which the size of the tumor made classical treatment difficult, and to highlight the role of orthovoltage as an alternative treatment mode with good...
PURPOSE: To identify factors significantly affecting recurrence rates after postoperative external beam radiotherapy (XRT) of keloids, and to delineate any radiation dose response and effects of radiation dose per fraction. METHODS AND MATERIALS: A comprehensive...
Radiation therapy (RT) for brain tumors is associated with neurocognitive toxicity which may be a result of damage to neural progenitor cells (NPCs). We present a novel technique to limit the radiation dose to NPC without compromising tumor coverage. A study was...
Radiation therapy can result in bone injury with the development of fractures and often can lead to delayed and nonunion of bone. There is no prevention or treatment for irradiation-induced bone injury. We irradiated the distal half of the mouse left femur to study...
BACKGROUND: The most common form of cancer in Brazil is non-melanoma skin cancer, which affects approximately 0.06% of the population. There are no public policies for its prevention and the economic impact of its diagnosis has yet to be established. OBJECTIVES: To...
The diagnosis and management of periocular cutaneous malignancies are essential components of an ophthalmologist's practice. Skin cancers comprise nearly one-third of newly diagnosed malignancies. Furthermore, the incidence of skin cancer appears to be increasing....
