Study adds to cancer-fighting promise of combined immunotherapy-radiation treatment

The study, led by Johns Hopkins Kimmel Cancer Center researchers, shows how in principle, radiation may specifically activate immune system cells responsible for attacking cancer cells, leading immune cells to “remember” how to fight cancer long after the cancer is gone. Andrew Sharabi, M.D., Ph.D., a resident in the Department of Radiation Oncology and Molecular Radiation Science at Johns Hopkins, is expected to present details of the study at the 2014 annual meeting of the American Society of Radiation Oncology (ASTRO) in San Francisco Sept. 15…

Professional recommendations against routine prostate cancer screening have little effect — ScienceDaily

The study, published as a research letter online in JAMA Internal Medicine, focused on the use of PSA — prostate-specific antigen — to test for prostate cancer. “We found that the effect of the guidelines recommending against the routine screening of elderly men in particular has been minimal at best,” says Jesse Sammon, D.O., a researcher at Henry Ford’s Vattikuti Urology Institute and lead author of the study. The researchers found an estimated 17 million men age 50 or older without a history of prostate cancer or prostate problems who reported undergoing PSA screening…

Benefit of endocrine therapy in elderly women with low risk hormone receptor positive breast cancer? — ScienceDaily

The results, which Fox Chase researchers presented at the American Society for Radiation Oncology’s 56th Annual Meeting on September 14, suggest that low-risk patients over 65 years old with small tumors may achieve comparable survival after treatment with adjuvant radiation therapy alone — without undergoing endocrine therapy. …

Benefit of endocrine therapy in elderly women with low risk hormone receptor positive breast cancer?

The results, which Fox Chase researchers presented at the American Society for Radiation Oncology’s 56th Annual Meeting on September 14, suggest that low-risk patients over 65 years old with small tumors may achieve comparable survival after treatment with adjuvant radiation therapy alone — without undergoing endocrine therapy. “When they’re treated with adjuvant radiation therapy alone, elderly women with small, low risk tumors may have acceptable results,” says Colin T. …

Patients with inoperable, early-stage lung cancer who receive stereotactic body radiation therapy have 40% five-year survival rate

RTOG 0236 was a Phase II North American multicenter trial from May 2004 until October 2006 of patients age 18 and older with biopsy-proven peripheral T1-T2 N0M0 non-small cell lung cancer (early stage with no lymph node involvement or metastases). Patients in the study all had medical conditions that precluded them from surgery, so they received SBRT, a specialized type of external beam therapy that uses focused radiation beams at a tumor using detailed imaging…

Mobility in cancer patients with malignant spinal cord compression

Malignant spinal cord compression (MSCC) is a complication of metastatic cancer mostly with bone involvement that occurs when a tumor’s secondary deposit presses on the spinal cord and nerves. This pressure exposes patients to neurological damage that can result in pain, loss of muscle strength and function of one or more of the senses. In some cases, the neurological damage can lead to paralysis of the entire body below the neck or paralysis of one or more limbs. …

Radiation therapy does not increase risk of lymphedema in node-negative breast cancer patients, study suggests — ScienceDaily

The original NSABP B-32 study was a randomized trial of sentinel node biopsy (SNB) versus SNB + axillary lymph node dissection (ALND) in 5,611 women with clinically node-negative breast cancer. The study was initiated to determine if SNB was as effective as ALND with fewer side effects. Although designed to assess the impact of type of axillary surgery specifically on lymphedema risk, the NSABP B-32 trial also provided the opportunity to evaluate the impact of radiation therapy (RT) on lymphedema risk. …

Long-term androgen deprivation therapy combined with high-dose radiation therapy for prostate cancer improves biochemical control and survival rates

Because prostate cancer cells typically require androgen hormones such as testosterone to grow, ADT is often recommended for patients with prostate cancer. Radiation therapy (RT) combined with ADT is an established, standard of care for patients with locally advanced prostate cancer…
