OBJECTIVE This retrospective observational study aims to explore the treatment procedure and outcomes of arthroscopically assisted radiotherapy for diffuse pigmented villonodular synovitis (PVNS) of the knee joint. METHODS From September 2006 to August 2011, 28 diffuse PVNS patients were diagnosed and treated under arthroscopy. Twenty six underwent post-operative radiotherapy. All patients we...
External-beam radiotherapy and brachytherapy, widely utilized as curative treatment modalities for prostate cancer, have undergone significant clinical and technological advances in recent decades. Contemporary radiotherapy treatment algorithms use pretreatment prognostic factors to stratify patients into low-, intermediate-, and high-risk groups that correlate with both pathologic stage of dis...
Several national and international organizations have developed various types and levels of external audits for radiotherapy dosimetry, either based on on-site review visits or using mailed dosimetry systems. Three major TLD (thermoluminescent dosimetry) networks make available postal dose audits to a large number of radiotherapy centres on a regular basis. These are the IAEA/WHO TLD postal dos...
Radiation enteritis is a significant complication of external beam radiotherapy (EBRT) to the pelvis, particularly in patients having high dose radiotherapy (> 80 Gy) and in those with a low pelvic peritoneal reflection allowing loops of small bowel to enter the radiation field. Laparoscopic insertion and subsequent removal of a pelvic tissue expander before and after external beam radiotherapy...
A retrospective analysis has been performed of the results of external beam radiotherapy for retinoblastoma using a whole eye technique. Local tumour control has been assessed in a consecutive series of 175 eyes in 142 children all of whom received external beam radiotherapy as the primary treatment for retinoblastoma. Follow up ranged from 2 to 17 years (median 9 years). Tumour control rates h...
BACKGROUND The combination of external-beam radiotherapy and brachytherapy is used commonly to treat men with prostate cancer. In this analysis, the authors examined the rate of biochemical recurrence (BR) and late grade > or =3 genitourinary (GU) and gastrointestinal (GI) toxicity after treatment with external-beam radiotherapy and brachytherapy in a multiinstitutional, cooperative group setti...
AIMS AND BACKGROUND To evaluate the impact of preoperative chemoradiation on sphincter preservation in patients with low-medium locally advanced resectable rectal cancer treated by four chemoradiation schedules. MATERIALS AND METHODS Between 1990 and 2002, 247 patients were treated according to four schedules of chemoradiotherapy: FUMIR (5-fluorouracil, mitomycin, external beam radiotherapy 3...
Background: Local recurrence in Nasopharyngeal Carcinoma (NPC) presents is a major challenge. Patients experience substantial morbidity as well as poor survival if no further treatment is offered. Residual or recurrent nasopharyngeal carcinoma is usually managed by chemotherapy, stereotactic radiosurgery, external beam radiation therapy (EBRT), interstitial, and intracavitary brachytherapy or s...
