Researchers analyzed data from 561 patients with high-risk prostate cancer from a multi-center, randomized phase III trial in Canada (PCS IV clinical trials, Gov. # NCT 00223171). …
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…
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. …
• 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. …
• 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…
