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.

Study suggests three-week course of radiation therapy effective for breast cancer patients

According to a study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO), a shortened, more intensive course of radiation given to the whole breast, along with an extra dose of radiation given to the surgical bed of the tumor (concomitant boost), has been shown to result in excellent local control at a median follow up of two years after treatment with no significant side effects.

Cancer patients want strong relationship with their radiation oncologist

What do patients want from their radiation oncologists? The most significant preference is that more than one-third of female cancer patients (37 percent) prefer to have their hands held by their radiation oncologists during important office visits, compared to 12 percent of men, according to a randomized study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Combination therapy before prostate removal may prevent recurrence of cancer

Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival.

Non-small cell lung cancer patients who undergo PCI decrease their risk of developing brain metastases

Patients with non-small cell lung cancer treated with preventative brain radiation (called prophylactic cranial irradiation or PCI), significantly decrease their risk of developing brain metastases (cancer spread in the brain) by more than 50 percent (from 18 percent to 8 percent), compared to those who did not receive the treatment, according to a randomized study presented at the plenary session November 2, 2009, at the 51st Annual Meeting of American Society for Radiation Oncology (ASTRO).

Patients who have an undetectable level of PSA after therapy have good chance of being cured

Fox Chase Cancer Center researchers report that radiation therapy alone can reduce prostate specific antigen (PSA) levels below detectable amounts in prostate cancer patients. Patients who have an undetectable level of PSA after therapy have less chance of biochemical failure than other patients and a good chance of being cured.

Obese lung cancer patients with diabeties more likely to develop chest wall pain after receiving stereotactic body radiation therapy

Obesity, not the amount of radiation given, is the greatest factor in whether early-stage lung cancer patients develop chest wall pain after receiving stereotactic body radiation therapy to the chest wall, with obese patients being more than twice as likely to develop chronic pain compared to those who have less body weight, according to a first-of-its-kind study presented Tuesday, November 3, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

HER2-positive breast cancer patients can be treated with Trastuzumab and adjuvant radiation therapy

Standard adjuvant treatment for HER2-positive breast cancer patients, following primary surgery for their cancer, is Trastuzumab (Herceptin)--typically used in combination with chemotherapy.

Combination of high-dose radiotherapy and chemotherapy shows encouraging results in treating LSCL

Treating limited stage small cell lung cancer(LSCL) with a combination of accelerated high-dose radiotherapy and chemotherapy has shown encouraging results, opening the door to larger scale investigation, according to new research from The University of Texas M. D. Anderson Cancer Center.

Radiation treatment as effective and as safe in reducing the risk of prostate cancer from returning

A shorter, five-week course of radiation treatment that delivers higher doses of radiation in fewer sessions, known as hypofractionation, appears to be just as effective and as safe in reducing the risk of prostate cancer from returning as standard radiation therapy, yet is delivered in two-and-a-half weeks less time, according to interim results of a randomized study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Advanced equipment targets radiation to specific areas in the brain

Radiation oncologists at Rush University Medical Center are intent on finding ways to avoid damage to the critically important hippocampus and limbic circuit of the brain when cranial radiation is required to treat existing or potential metastatic cancers.

Stereotactic radiosurgery effectively controls pain in patients with cancer

Stereotactic radiosurgery (SRS), a radiation therapy procedure pioneered at the University of Pittsburgh Cancer Institute (UPCI) that precisely delivers a large dose of radiation to tumors, effectively controls pain in patients with cancer that has spread to the spine, according to researchers from UPCI.

PET imaging is not the basis for increasing dosage level

Positron emission tomography (PET) imaging of non-small cell lung cancer prior to receiving radiation therapy should not be the basis for determining areas that may benefit from higher doses of radiation, according to research presented by investigators at Thomas Jefferson University Hospital at the 51st ASTRO Annual Meeting (Abstract #2583/B-186).

$Optic nerve sheath meningioma patients can be cured using fractionated stereotactic radiotherapy$

Optic nerve sheath meningioma patients can be cured using fractionated stereotactic radiotherapy

Optic nerve sheath meningiomas are rare tumors that are traditionally treated with surgery, which is typically a blinding procedure. However, researchers from Thomas Jefferson University Hospital have found that a specialized type of radiation therapy offers the same local control, with fewer adverse effects on vision.

SBRT stops the growth of cancer for 98% of patients with NSCLC

Stereotactic body radiation therapy (SBRT) stopped the growth of cancer at its original site in the lung for three years among nearly 98 percent of patients with early non-small cell lung cancer (NSCLC) who are unable to have the cancer surgically removed, according to an updated three-year study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

New study to assess preventative brain radiation therapy for lung cancer patients

A new study is taking a closer look at the benefits versus risks for lung cancer patients to undergo preventative brain radiation therapy as a means to stop cancer from spreading to the brain.

Melanoma patients treated with radiation after surgery at lower risk of cancer recurrence

High-risk melanoma patients who are treated with radiation after surgery have a significantly lower risk of their cancer returning to the lymph nodes (19 percent), compared to those patients who do not have radiation therapy (31 percent), according to the first randomized study of its kind presented at the plenary session, November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).
