Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Antioxidants inositol and inositol hexaphosphate could provide all-purpose radiation protection

Two common dietary molecules found in legumes and bran could protect DNA from the harmful effects of radiation, researchers from the University of Maryland report.

Manipulation of MOF enzyme may make tumors more sensitive to radiation therapy

To make tumors more sensitive to the killing power of radiation is a key aspiration for many radiation oncologists. Researchers at Washington University School of Medicine in St. Louis have uncovered new information that leads them closer to that goal.

Radiation seed implant decreases risk of death over watchful waiting/active surveillance for prostate cancer

Prostate cancer patients cut their risk of dying of the disease in half when they receive radiation seed implants (brachytherapy) to treat their cancer, compared to those who don't receive active treatment (watchful waiting/active surveillance), within six months from being diagnosed with localized prostate cancer, according to a study presented October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Radiation after surgery keeps high-risk prostate cancer at bay

An analysis of data involving more than 2,000 patients from 17 U.S. institutions demonstrates that men with high-risk prostate cancer who receive radiation therapy after a prostatectomy were less likely to have a recurrence of disease.

Quality of life most important for survival in advanced non-small cell lung patients

Healthcare providers have observed it for years -- patients who appear to have a better quality of life while battling their cancer live longer.

Stereotactic radiation is effective as surgery against nerve tumor

Specifically aimed, "stereotactic" radiation may be as good as surgery - and in some cases, even better - in treating benign but potentially devastating brain tumors called non-acoustic schwannomas, according to a study by rradiation oncologists at the Kimmel Cancer Center at Thomas Jefferson University and Thomas Jefferson University Hospital in Philadelphia.

Which lung volumes to use for radiotherapy planning of lung cancer

A new method to standardize the reporting of radiation dose volumes in the use of four-dimensional computed tomography (4D-CT) can lead to a more accurate radiation dose to the lungs in lung cancers, thereby lowering the risk of lung injury, according to a study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Brachytherapy effectively cures prostate cancer in young men

Radiation seed implants (brachytherapy) are just as effective at curing prostate cancer in younger men (aged 60 and younger) as they are in older men, according to a study presented at a scientific session on October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Radiation plus chemo quadruples survival time for fatal brain cancer

Over four times as many patients with a rapidly fatal type of brain cancer, glioblastoma multiforme (GBM), who are treated with the chemotherapy drug temozolomide (TMZ) and radiation therapy, can live for four years after diagnosis, compared to those who receive only radiation treatment, according to updated results of a large, international trial presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Preventing lung scarring may extend lives of lung cancer patients

Researchers have found that using a special type of drug called a pharmaceutical monoclonal antibody to block the integrin beta6-TGF-beta pathway prevents a serious side effect of radiation therapy for lung cancer patients – pulmonary fibrosis (scarring of the lungs), thereby extending patients' lives and improving their quality of life, according to a study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

New treatment option studied for bladder cancer

A chemotherapy regimen for patients with advanced bladder cancer who aren't eligible for standard treatment is under study at the Medical College of Georgia.

Higher radiation doses over shorter periods of time for prostate cancer doesn't lead to sexual dysfunction

Recent advances in the delivery of radiation therapy for prostate cancer are fueling a new trend of providing higher radiation doses over shorter periods of time.

Extra radiation dose prevents breast cancer return in young women

Women 40 years and younger with early-stage breast cancer who receive an additional high dose of radiation (boost dose) after undergoing breast-conserving surgery (lumpectomy) and standard radiation treatment are almost twice as likely to be free of cancer 10 years after treatment compared to those who don't receive the boost dose, according to a large European study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Do statins make radiation more effective at curing prostate cancer?

Patients with prostate cancer who receive high-dose radiation treatment and also take statin drugs commonly used to lower cholesterol have a 10 percent higher chance of being cured of their cancer at 10 years after diagnosis (76 percent), compared to those who don't take these medications (66 percent), according to a study presented at a scientific session October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Study confirms the aggressive nature of breast cancer in African-American women

Contrary to previous studies, African-American women with early-stage breast cancer who have surgery to remove the cancer (lumpectomy) followed by radiation therapy have a higher chance of their cancer coming back in the breast and lymph nodes 10 years after diagnosis, compared to their Caucasian counterparts, according to the largest study of its kind, presented at a scientific session October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Women with breast cancer have less dermatitis when treated with intensity-modulated radiation therapy

All women treated with radiation therapy for breast cancer are at risk of developing dermatitis - a sometimes-painful skin condition caused by radiation as it makes its way through the skin to the tumor area and tissue within the breast.
