New data show that high maximum standard uptake value (SUVmax) of F-18-FDG in the lymph nodes prior to treatment could be an independent indicator of disease recurrence. http://medicalxpress.com/news/2012-09-pretreatment-petct-imaging-lymph-nodes.html Cancer Tue, 04 Sep 2012 14:50:53 EST news265989042 (HealthDay) -- For adult patients with acute or chronic low back pain (LBP), assessing the baseline score for catastrophizing does not help clinicians in routine clinical practice predict the evolution of LBP or the patient's disability at three months, according to a study published online July 23 in The Spine Journal. http://medicalxpress.com/news/2012-08-catastrophizing-doesnt-pain-evolution.html Diseases, Conditions, Syndromes Thu, 16 Aug 2012 17:36:42 EST news264357378 (HealthDay) -- In patients with invasive breast cancer, lymphovascular invasion (LVI) is a strong and independent predictor of both breast cancer-specific survival (BCSS) and distant metastasis-free survival (DMFS), according to a study published in the Aug. 1 issue of Cancer. http://medicalxpress.com/news/2012-07-lymphovascular-invasion-independent-predictor-survival.html Cancer Sun, 29 Jul 2012 17:04:47 EST news262800180 A DNA repair pathway-focused score has the potential to help determine if first-line platinum based chemotherapy can benefit advanced-stage ovarian cancer patients, according to a study published April 13 in the Journal of the National Cancer Institute. http://medicalxpress.com/news/2012-04-dna-pathway-score-chemotherapy-response.html Cancer Fri, 13 Apr 2012 16:00:01 EST news253457787 Researchers at the Kimmel Cancer Center at Jefferson have demonstrated for the first time that the metabolic biomarker MCT4 directly links clinical outcomes with a new model of tumor metabolism that has patients "feeding" their cancer cells.

Currently, the NRC recommends outpatient treatment for patients receiving radioactive iodine after total or near-total thyroidectomy; however, several groups have been urging NRC to mandate overnight hospital stays to protect others from a perceived risk of radiation exposure. http://medicalxpress.com/news/2011-05-case-current-i-therapy.html Other Thu, 05 May 2011 13:55:38 EST news223822525
