New radiosurgery technology provides highly accurate treatment, greater patient comfort

The study shows the Edge™ Radiosurgery Suite is able to target cancer tumors within 1 mm, providing sub-millimeter accuracy with extreme precision. “Radiosurgery is just one shot of precision radiation with a very high dose to treat tumors,” says study lead author Ning Wen, Ph.D., a physicist with the Department of Radiation Oncology at Henry Ford. …

Chemotherapy and stereotactic ablative radiation consecutively may be promising for patients with advanced pancreatic cancer

Surgery is the only potentially curative therapy for individuals with pancreatic ductal adenocarcinoma (PDA), the most common type of pancreatic cancer. However, pancreatic cancer is often diagnosed at an advanced stage, making surgical removal of the tumor or the organ challenging, if not impossible. …

Patients who never smoked or who quit smoking have lower risk of developing secondary cancers

The analysis studied the association between patients’ smoking histories and their risks of developing SPLC, which is defined as a new lung cancer unrelated to the initial tumor based on histology and location in the lung. The study analyzed 1,484 patients (372 current smokers, 1,014 former smokers and 98 never smokers) who underwent surgery, with or without adjuvant chemotherapy or radiation therapy, for stage I-IIIA NSCLC at Duke University Medical Center between 1995 and 2008. Baseline covariates and oncologic outcomes including local control (LC), development of distant metastases (DM), overall survival (OS) and rates of SPLC were assessed. …

Study identifies when and how much various prostate cancer treatments will impact urinary and sexual functioning

Looking over data gathered from more than 17,000 surveys completed by men diagnosed with prostate cancer, Fox Chase researchers tracked when patients’ urinary and sexual symptoms changed following each type of treatment, and by how much. “The ultimate goal,” says study author Matthew Johnson, MD, Resident Physician in the Department of Radiation Oncology at Fox Chase, “is to develop a predictive tool that lets patients decide which treatment is right for them based on the symptoms they have beforehand, and their tolerance for any change — even temporary — in those symptoms.” After a diagnosis of prostate cancer, men have multiple treatment options, including surgery to remove the prostate and several types of radiation therapy. They can receive external beam radiation directed towards their prostate, known as intensity modulated radiation therapy (IMRT), or undergo a procedure that implants radioactive seeds in their prostate called low dose rate brachytherapy (LDR). …

Majority of prostate cancer patients surveyed five years after treatment with vessel-sparing radiation therapy report preserved sexual function

The study examined the patient-reported outcomes of 91 men with prostate cancer who received MRI-guided, vessel-sparing radiation at University of Michigan Providence Cancer Institute. The vessel-sparing radiation technique limits the amount of radiation to critical erectile tissues using MRI scans to identify the blood vessels responsible for erections. …

Cancer-fighting cocktail demonstrates promising results as treatment for advanced cervical cancer

The cancer-fighting cocktail, which combines the chemotherapy drug cisplatin with pemetrexed — an agent that stops cancer cells from dividing — showed promising results for advanced, persistent, or recurrent cervical cancer. “We found that pemetrexed combined with cisplatin is less toxic, well tolerated, and should be developed for further treatment of cervical cancer,” said gynecologic oncology specialist Dr. …

Five radiation oncology treatments to question

• Don’t recommend radiation following hysterectomy for endometrial cancer patients with low-risk disease. Patients with low-risk endometrial cancer, including no residual disease in hysterectomy despite positive biopsy, grade 1 or 2 with <50 percent myometrial invasion and no additional high-risk features such as age >60, lymphovascular space invasion or cervical involvement have a very low risk of recurrence following surgery. Meta-analysis studies of radiation therapy for low-risk endometrial cancer demonstrate increased side effects with no benefit in overall survival compared with surgery alone. • Don’t routinely offer radiation therapy for patients who have resected non-small cell lung cancer (NSCLC), negative margins, N0-1 disease…

Improved survival shown in early-stage Hodgkin’s disease patients who receive radiation therapy

Researchers evaluated clinical features and survival outcomes among 41,502 patients diagnosed with stage I and II Hodgkin’s Disease from 1998 to 2011 from a prospectively collected database — the National Cancer Data Base (NCDB), which is composed of cases from 1,500 sites and represents >75 percent of all cancers diagnosed in the U.S. The average patient age was 37 (range: 18 — 90), with a median follow-up of 7.5 years. The association between RT use, co-variables and outcome were assessed in a multivariate Cox proportional hazards model…
