Radiation therapy (in North America), or radiotherapy (in the UK and Australia) also called radiation oncology, and sometimes abbreviated to XRT, is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis).

Over one-third of people with terminal cancer do not receive entitled benefits: Study

Cancer radiotherapy can increase risk of cardiovascular disease later in life

For an as yet unknown reason, cancer radiotherapy can increase the risk of cardiovascular disease later in life, a problem that is growing as more and more people survive their cancer diagnosis. New research from Karolinska Institutet now suggests that sustained inflammation induced by post-radiotherapy changes in the gene expression in the arteries could be the cause.

Scientists identify new growth factor that stimulates expansion of hematopoietic stem cells

Scientists at Duke University Medical Center have identified a new growth factor that stimulates the expansion and regeneration of hematopoietic (blood-forming) stem cells in culture and in laboratory animals. The discovery, appearing in the journal Nature Medicine, may help researchers overcome one of the most frustrating barriers to cellular therapy: the fact that stem cells are so few in number and so stubbornly resistant to expansion.

SBRT can improve survival rates for patients with inoperable non-small cell lung cancer

Highly-focused stereotactic body radiation therapy (SBRT) can eliminate the targeted tumor while avoiding treatment-related illness and may ultimately improve survival for patients with inoperable non-small cell lung cancer, according to early findings of a Radiation Therapy Oncology Group study published in the March 17 cancer-themed issue of the Journal of the American Medical Association.

SBRT doubles rate of primary tumor control compared to conventional radiotherapy

Early findings suggest a radiation therapy that involves numerous highly-focused and potent radiation beams provides targeted tumor control in nearly all patients, reduces treatment-related illness, and may ultimately improve survival for patients with inoperable non-small cell lung cancer, according to a study in the March 17 issue of JAMA, a theme issue on cancer.

SBRT may improve survival rates for lung-cancer patients: Study

A radiation therapy that uses multiple radiation beams to target tumors precisely has been shown to eliminate the primary tumor and ultimately may improve survival rates for lung-cancer patients unable to undergo surgery, according to UT Southwestern Medical Center physicians who led a national clinical trial of the treatment.

Cytheris study: rhIL-7 treatment restores T cell trafficking and improves survival in animal model of sepsis

Cytheris SA, a clinical stage biopharmaceutical company focused on research and development of new therapies for immune modulation, today announced publication of data from a preclinical study in a clinically relevant animal model of sepsis showing that recombinant human Interleukin-7 (rhIL-7) treatment not only restores T cell trafficking and function, but also translates into improved survival.

Bone implants that support and release chemotherapeutical agents in ciclodextrin nanocapsule

Chemotherapy, followed by the surgical removal of the affected tissue is the treatment usually adapted to bone tumors. An implant which can fill the areas of subtraction, while releasing chemotherapeutical agents locally, in a controlled manner, during the treatment period, is the aim of a research led by the Research Centre in Ceramic Material and Composites (CICECO/UA). In these experiences, specialists are using potential "anti-tumor" drugs coated by nanocapsules.

Latest treatment options for colorectal cancer highlighted at NCCN Annual Conference

Despite statistics stating that colorectal cancer is the fourth most frequently diagnosed cancer in men and women in the United States, mortality from colon cancer has decreased slightly over the past 30 years, possibly because of earlier diagnoses through screening and better treatment modalities.

Breast cancer patients with early stage disease may not benefit from radiation after mastectomy

Breast cancer patients with early stage disease that has spread to only one lymph node may not benefit from radiation after mastectomy, because of the low present-day risk of recurrence following modern surgery and systemic therapy, a finding that could one day change the course of treatment for thousands of women diagnosed each year, according to researchers at The University of Texas M. D. Anderson Cancer.

Longer wait for radiation treatment after breast cancer surgery increases risk of recurrence in older women

The longer older women wait for radiation treatment after undergoing surgery for breast cancer, the greater the chances of the disease coming back, an international team of scientists has warned.

Arc radiotherapy treatments: Breakthrough in image-guided targeting of prostate tumors

Researchers in the US and Denmark have made a breakthrough in image-guided targeting of prostate tumors during arc radiotherapy treatments. In research partially supported by Varian Medical Systems, physicists at Stanford University (California, USA) and Aarhus University Hospital (Aarhus, Denmark) have devised a method for 'real-time' tracking of the prostate motion using Varian's On-Board Imager® that shows promise in paving the way for advanced clinical treatments.
