(HealthDay)—Given the shift in the focus of drug development for Alzheimer's disease toward earlier disease stages, before the onset of dementia, regulatory guidelines need to evolve, according to a perspective piece published online March 13 in the New England Journal of Medicine. http://medicalxpress.com/news/2013-03-evolve-drugs-early-alzheimer.html Alzheimer's disease & dementia Thu, 14 Mar 2013 19:20:01 EST news282506836 For patients with medically operable clinical stage I non–small-cell lung cancer (NSCLC), lobectomy or pneumonectomy is the standard approach. For patients with medically inoperable stage I NSCLC, stereotactic body radiotherapy (SBRT) has become a standard of care. Researchers from the Washington University School of Medicine wanted to compare the patterns of failure (primary tumor control, local control, regional control, and distant control) between each method. http://medicalxpress.com/news/2013-01-patterns-failure-sbrt-lobectomy-pneumonectomy.html Cancer Tue, 15 Jan 2013 11:39:09 EST news277472335 Prostate cancer experts at Johns Hopkins have developed an updated version of the Partin Tables, a tool to help men diagnosed with prostate cancer and their doctors to better assess their chance of a surgical cure. The updated tool, based on a study of more than 5,600 men treated at The Johns Hopkins Hospital from 2006 to 2011, is published in the Jan. 3 issue of the British Journal of Urology International. http://medicalxpress.com/news/2013-01-partin-tables-tool-prostate-cancer.html Cancer Fri, 04 Jan 2013 07:22:01 EST news276506378 People who study or treat Alzheimer's disease and its earliest clinical stage, mild cognitive impairment (MCI), have focused attention on the obvious short-term memory problems. But a new study suggests that people on the road to Alzheimer's may actually have problems early on in processing semantic or knowledge-based information, which could have much broader implications for how patients function in their lives. http://medicalxpress.com/news/2012-12-early-cognitive-problems-eventually-alzheimer.html Alzheimer's disease & dementia Fri, 28 Dec 2012 11:06:02 EST news275915154 (HealthDay) -- Active surveillance of patients with small renal masses is driven by a tumor size less than 3 cm, poor performance score (PS), and an endophytic lesion, among other patient, tumor, and surgeon characteristics, according to research published in the May issue of Urology. http://medicalxpress.com/news/2012-05-criteria-surveillance-small-renal-mass.html Other Mon, 07 May 2012 17:10:01 EST news255626924 (HealthDay) -- In patients with locally advanced rectal cancer undergoing radical resection, response to neoadjuvant chemoradiotherapy is an early marker that correlates with rates of recurrence-free survival, distant metastases, and local recurrences, according to research published online April 9 in the Journal of Clinical Oncology. http://medicalxpress.com/news/2012-04-early-response-indicator-rectal-cancer.html Cancer Tue, 10 Apr 2012 14:40:01 EST news253286418 Whether chemotherapy is given before or after breast-conserving therapy (BCT) does not have an impact on long-term local-regional outcomes, suggesting treatment success is due more to biologic factors than chemotherapy timing, according to a study by researchers at The University of Texas MD Anderson Cancer Center. http://medicalxpress.com/news/2011-09-chemotherapy-effective-breast-cancer-surgery.html Cancer Thu, 08 Sep 2011 15:15:25 EST news234713696 A new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease. A link also was found between smoking at the time of prostate cancer diagnosis and aggressive prostate cancer, overall mortality (death) and cardiovascular disease mortality. http://medicalxpress.com/news/2011-06-prostate-cancer-recurrence-death.html Cancer Tue, 21 Jun 2011 16:26:17 EST news227892240
