Recent advances have improved the effectiveness, decreased the complications, and expanded the implications of radiation therapy. These advances include three-dimensional conformal radiation therapy, intensity-modulated radiation therapy, stereotactic radiotherapy, brachytherapy, and radioimmunotherapy. Each of these modalities has improved radiation targeting, thereby limiting radiation exposu...

Conventional radiotherapy for cervical cancer relies on clinical examination, 3-dimensional conformal radiotherapy (3D-CRT), and 2-dimensional intracavitary brachytherapy. Excellent local control and survival have been obtained for small early stage cervical cancer with definitive radiotherapy. For bulky and locally advanced disease, the addition of chemotherapy has improved the prognosis but t...

BACKGROUND Patients with brain metastases from lung cancer have poor prognoses and short survival time, and they are often excluded from clinical trials. Whole-cranial irradiation is considered to be the standard treatment, but its efficacy is not satisfactory. The purpose of this phase II clinical trial was to evaluate the preliminary efficacy and safety of the treatment of whole-brain irradia...

Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...

RODRIGUES G. Is intensity-modulated radiotherapy for prostate cancer ready for prime-time? Can J Urol 2012;19(4):6381-6382. the therapeutic ratio between the positive anticancer effect of radiotherapy on macroscopic and microscopic disease and the negative normal tissue effects leading to both acute and late radiotherapy toxicities. In the context of prostate cancer radiotherapy, these technolo...

OBJECTIVES The objectives of this study were to assess the clinical effects of an integrated program consisting of concurrent preoperative combined paclitaxel and nedaplatin chemotherapy and three-dimensional conformal radiotherapy followed by surgery intended to cure oral squamous cell carcinoma and to determine whether this integrated program is feasible and effective with respect to the trea...
