Intrafractional motion management in external beam radiotherapy
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2019The recent advancements in radiotherapy technologies have made delivery of the highly conformal dose to the target volume possible. With the increasing popularity of delivering high dose per fraction in modern radiotherapy schemes such as in stereotactic body radiotherapy and stereotactic body ablative therapy, high degree of treatment precision is ...

Palliative radiotherapy for bone metastases: conventional external beam radiotherapy
International Journal of Clinical OncologyConventional external beam radiotherapy (cEBRT) is effective for managing symptomatic bone metastases and continues to be in demand despite advances in stereotactic body radiotherapy. This review provides an overview of cEBRT for bone metastases, with a focus on the following: (1) Initial palliative radiotherapy: randomized controlled trials and meta ...

External-Beam Radiotherapy for Localized Prostate Cancer
New England Journal of Medicine, 2006External-beam radiotherapy is recommended for a 69-year-old man with localized prostate cancer. This therapy has evolved rapidly owing to the development of sophisticated techniques for focusing the radiation beam precisely on its target. Important adverse effects include radiation proctitis, cystitis, urethritis, and erectile dysfunction.

External-beam radiotherapy in the management of liver metastases
Seminars in Oncology, 2002This review discusses the importance of palliation of liver metastases. Although colorectal cancer comprises the majority of patients with metastatic liver disease, a number of other malignancies can be involved. Palliation of metastatic disease to liver has generally not included the use of external-beam radiotherapy because of restricted liver ...

Advanced Image-Guided External Beam Radiotherapy
2008The goal of radiation therapy is to eradicate tumor stem cells while sparing healthy tissue. Therefore, the first aim must be to delineate tumor from healthy tissue. Advanced imaging techniques will enable one to reduce the uncertainty of microscopic extension of disease.

External-beam radiotherapy for localized extrahepatic cholangiocarcinoma
International Journal of Radiation Oncology*Biology*Physics, 2006The role of radiation therapy (RT) in extrahepatic cholangiocarcinoma (EHCC) is not clear and only limited reports exist on the use of this modality. We have reviewed our institutional experience to determine the pattern of failure in patients after potentially curative resection and the expected outcomes after adjuvant RT and in unresectable patients ...

External beam radiotherapy in the management of ovarian carcinoma
Radiotherapy and Oncology, 1993Between 1970 and 1983, 345 patients with ovarian cancer clinical stage I, II, and III were irradiated postoperatively. Five-year NED survival was achieved in 41.7% of patients. The most important prognostic factors were histological grade and clinical stage of cancer.

External beam and conformal radiotherapy in the management of gliomas
2003External beam radiotherapy remains an important local treatment modality in both high and low grade gliomas, however its contribution to outcome remains modest. In high grade tumours this is because of their extreme clinical radioresistance, with local recurrences occurring even after doses over 70 Gy.

Management of the complications of external beam radiotherapy and brachytherapy
Current Prostate Reports, 2006External beam radiation therapy (EBRT) and brachytherapy are common treatment modalities for newly diagnosed prostate cancer. What complications can patients and physicians expect following these therapies? How are these conditions diagnosed and treated? In this article, we examine several of the most common acute and delayed complications of radiation

Role of External Beam Radiotherapy in Hepatocellular Carcinoma
Clinics in Liver Disease, 2020External beam radiotherapy (EBRT) has improved efficacy and safety with advancements in technology and techniques. EBRT plays an important role in management of hepatocellular carcinoma (HCC). In resectable cases, EBRT serves as a bridge to transplantation or improves local control through adjuvant radiotherapy.
