4. Is moderate hypofractionation accepted as a new standard of care in north america for prostate cancer patients treated with external beam radiotherapy? Survey of genitourinary expert radiation oncologists
ABSTRACT Introduction: Several recent randomized clinical trials have evaluated hypofractionated regimens against conventionally fractionated EBRT and shown similar effectiveness with conflicting toxicity results. The current view regarding hypofractionation compared to conventional EBRT among North American genitourinary experts for management of prostate

5. Potential role of sorafenib as neoadjuvant therapy in unresectable papillary thyroid cancer
Summary Total thyroidectomy, radioiodine (RAI) therapy, and TSH suppression are the mainstay treatment for differentiated thyroid carcinomas (DTCs). Treatments for metastatic disease include surgery, external-beam radiotherapy, RAI, and kinase inhibitors for progressive iodine-refractory disease. Unresectable locoregional disease remains a challenge, as stan

7. Thyroid function, autoimmunity and nodules in hematological malignancies
Objective Hematological malignancies encompass a large spectrum of disease entities whose treatment by chemo/radiotherapy could lead to thyroid complications. To the best of our knowledge, no study has simultaneously addressed thyroid function, autoimmunity and nodularity. Therefore, we decided to conduct one.Materials and methods We evaluated 82 Caucasian p

8. Optimizing Penile Length in Patients Undergoing Partial Penectomy for Penile Cancer: Novel Application of the Ventral Phalloplasty Oncoplastic Technique
The ventral phalloplasty (VP) has been well described in modern day penile prosthesis surgery. The main objectives of this maneuver are to increase perceived length and patient satisfaction and to counteract the natural 1-2 cm average loss in length when performing implantation of an inflatable penile prosthesis. Similarly, this video represents a new adapta

12. Programa de controle da qualidade dosimétrico, validado com auxílio de filme radiocrômico, aplicado à radioterapia estereotáxica / Dosimetric quality assurance with the help of the radiochromic film, applied to stereotactic radiotherapy.
Radiation therapy of brain lesions near critical structures requires a highly accurate location and dose. The accuracy in dose delivery should be accompanied by an accurate quality control in devices involving the practice. The commissioning of the planning system is to ascertain and confirm the calculations performed by the system, but even with all quality
