Adding A Second Robot May Help Surgeon to Spare Nerves Controlling Erections
Johns Hopkins researchers have developed a new technique that may improve robotic prostate surgery by using a second robot for taking three-dimensional ultrasound images of the prostate and surrounding structures during the procedure. These images can potentially help surgeons spot the nerve bundle that controls erectile function.
Cancer Vaccine Plus Interleukin-7 Boosts Immune Response to Cancer
Sunday, April 26 2009 13:00
Scientists have discovered that combining interleukin-7 (IL-7) – a key component of the immune system – with a viral vaccine improves the ability of the immune system to attack tumors. A Canadian team at The Campbell Family Institute for Breast Cancer Research (CFIBCR) at Princess Margaret Hospital, Toronto say their discovery could be included in new clinical trials that use a patient’s own cells to destroy tumors.
CT Scans: Most Doctors Lack Knowledge of Radiation Exposure Risks
Scans for diagnosis and staging - CT:Computerised Tomography scan

Ordering physicians have limited knowledge of CT-related radiation exposure and its associated risks, according to a study performed at the Carilion Clinic in Roanoke, VA.
"More than 100 surveys were completed by physicians from various specialties who order CT scans at a tertiary-care teaching hospital," said Jeremy McBride, MD, lead author of the study. "When physician knowledge regarding radiation was assessed, 63% underestimated the radiation dose of one abdominal-pelvic CT in chest radiograph equivalents."
MRI: Effective Tool for Staging Prostate Cancer
MRI-Magnetic Resonance Imaging

In patients with prostate cancer undergoing prostatectomy, Magnetic Resonance Imaging (MRI) can play an important role in determining if the cancer is restricted to the prostate gland or if it has spread beyond the capsule.
This is the finding of a study performed at the University of California, Los Angeles, CA. The study included a review of 119 patients who were referred for prostate MRI prior to prostatectomy.
"Results showed that MRI correctly identified 87 out of 92 (95%) of patients with T2 and 6 out of 8 (75%) of patients with T3 disease (T2 means the disease is organ confined and T3 means the disease has locally spread beyond the prostate)," said Timothy McClure, MD, lead author of the study. Steven Raman, MD, worked with Dr. McClure on this study.
New Method of Teaching Immune System to Recognize A Prostate Cancer Marker, PSMA
Last Updated (Tuesday, April 28 2009 03:38) Monday, April 20 2009 02:26
PSMA (prostate specific membrane antigen) is a marker expressed in advanced prostate cancer in many men including men with bone metastases. Several methods of exploiting it to target cells and prostate tumors are in clinical trials or under research. Prostate cancer patients in an ongoing Phase 1 study have been treated with designer T cells modified by retroviral gene therapy.
