Radiation therapy is effective in achieving local control and palliation in patients with pancreatic neuroendocrine tumors (PNTs), despite such tumors being commonly considered resistant to radiation therapy, according to a largest of its kind study in the November 15 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO). PNT is a very rare form of pancreatic cancer that can stay confined to the...

PALO ALTO, Calif., Nov. 12 /PRNewswire-FirstCall/ -- Researchers from the University of California, Irvine Medical Center reported last week that image-guided RapidArc® radiotherapy from Varian Medical Systems (NYSE: VAR) has clinical advantages over earlier fixed-beam approaches to stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) for treating cancer. RapidArc, Varian's technology for delivering volumetric modulated arc therapy (VMAT), enables...

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 sides effects. "The observations to date suggest that a three-week...

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). Another significant finding is that almost three-quarters of the patients...

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. The Phase II study was presented Nov. 3 in an oral session at the annual meeting of the American Society for Radiation Oncology (ASTRO), by Ritsuko Komaki, M.D., professor and program director of Lung Cancer...

Hypofractionated radiation treatment, a newer type of radiation treatment that delivers higher doses of radiation in fewer treatments than conventional radiation therapy, is significantly more effective in stopping cancer from growing in high risk patients, compared to receiving standard radiation treatment, according to a study presented November 4, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO). In addition, findings show there is no increased risk...

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). "The study...

Proton beam therapy can be safely delivered to men with prostate cancer and has minimal urinary and rectal side effects, according to a study presented November 2, 2009, at the American Society for Radiation Oncology's 51st Annual Meeting in Chicago. Researchers sought to determine if delivering higher doses of radiation with proton therapy would cause early harmful side effects to urinary function within the genitourinary system (GU) function and rectal function within the gastrointestinal...
