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...
Radiotherapy is an important treatment modality for 40-50% of children with cancer. There is concern about late effects, particularly the neuropsychological effects of CNS irradiation, and orthopaedic effects. It is important to administer the highest standard of radiotherapy, incorporating departmental quality assurance. Meticulous planning is essential to achieve local tumour control with the...
Intraoperative radiotherapy (IORT) for breast cancer has challenged the standard external beam radiotherapy (EBRT) and has been shown to be non-inferior for treating early breast cancer in the past decade. Several technologies have been tested for IORT and various randomised controlled trials are still ongoing. Different methods of application of IORT have also been evaluated, from early breast...
BACKGROUND To compare the dosimetric coverage of target volumes and organs at risk in the radical treatment of nasopharyngeal carcinoma (NPC) between intensity-modulated radiotherapy (IMRT) and three- dimensional conformal radiotherapy (3DCRT). MATERIALS AND METHODS Data from 10 consecutive patients treated with IMRT from June-October 2011 in Penang General Hospital were collected retrospecti...
Intensity-modulated radiation therapy (IMRT) is frequently utilized after prostatectomy without strong evidence for an improvement in outcomes compared to conformal radiation therapy (RT). We analyzed a large group of patients treated with RT after radical prostatectomy (RP) to compare complications after IMRT and CRT. The Surveillance, Epidemiology and End Results (SEER)-Medicare database was ...
OBJECTIVE We evaluated health-related quality of life (HRQOL) in patients with localized prostate cancer who underwent intensity-modulated radiation therapy (IMRT) or three-field conformal radiotherapy (3DCRT). METHODS A total of 97 patients underwent 3DCRT and 36 underwent IMRT for localized prostate cancer between 2002 and 2004. We measured the general and disease-specific HRQOL with the Me...
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...
