Editor's Choice Main Category: Cancer / Oncology Article Date: 11 Jun 2012 - 11:00 PDT Current ratings for: 'Vismodegib For Treatment Of Patients With Basal Cell Carcinoma' The study, published in the New England Journal of Medicine (NEJM), found that vismodegib healed visible lesions or shrank tumors in 30% of patients whose cancer had metastasized and in 43% of patients with locally advanced BCC. Although BCC is the most prevalent type of skin cancer in Europe, there are currently no approved drugs for advanced BCC available in the UK. BCCs, which almost always occur on parts of the body excessively exposed to the sun, can cause disfigurement if not treated promptly and can also develop into a potentially life threatening advanced form of BCC. Dr John Lear, Consultant Dermatologist at Manchester Royal Infirmary, explained: According to the researchers, 9.5 months was the median duration of progression-free survival (PFS) among patients taking vismodegib. In addition, they found that the most common side effects included: Written By Grace Rattue Copyright: Medical News Today Not to be reproduced without permission of Medical News Today MLA Grace Rattue.

Public release date: 11-Jun-2012 [ | E-mail | Share ] Contact: Susan Martonik smartonik@snm.org 703-652-6773 Society of Nuclear Medicine Miami Beach, Fla.Research revealed at the Society of Nuclear Medicine's 2012 Annual Meeting explores treatment with a newly developed type of radioimmunotherapy used for treating a resistant form of kidney cancer. The agent is able to hone in on the disease, called clear cell renal carcinoma, and kill the cancer by delivering radiation directly to it. However, the study shows that its effectiveness could be diminished when used after another anti-cancer therapy. The radioimmunotherapy highlighted in this study is radiolabeled monoclonal antibody girentuximab (also known as cG250), a potent anticancer therapy that delivers a precise and powerful dose of radiation just at the site of cancerous tissues. Theobjective of the study was to investigate the effect of the widely used tyrosine kinase inhibitor (TKI) on the targeting of In-111-cG250 in clear cell renal cancer patients. "This research has important implications for future therapeutic regimens for patients with clear cell renal carcinoma," says Stijn Muselaers, M.D., lead physician of the study at Radboud University Nijmegen Medical Centre in Nijmegen, The Netherlands. "This study indicates that imaging and therapy of tumors with radiolabeled … Continue reading →

Public release date: 11-Jun-2012 [ | E-mail | Share ] Contact: Kim Irwin kirwin@mednet.ucla.edu 310-206-2805 University of California - Los Angeles Health Sciences UCLA stem cell scientists purified a subset of stem cells found in fat tissue and made from them bone that was formed faster and was of higher quality than bone grown using traditional methods, a finding that may one day eliminate the need for painful bone grafts that use material taken from the patient during invasive procedures. Adipose, or fat, tissue is thought to be an ideal source of cells called mesenchymal stem cells - capable of developing into bone, cartilage, muscle and other tissues - because they are plentiful and easily attained through procedures such as liposuction, said Dr. Chia Soo, vice chair for research at UCLA Plastic and Reconstructive Surgery. The co-senior authors on the project, Soo and Bruno Pault, are members of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. Traditionally, cells taken from fat had to be cultured for weeks to isolate the stem cells which could become bone, and their expansion increases risk of infection and genetic instability. A fresh, non-cultured cell composition called stromal … Continue reading →

ScienceDaily (June 11, 2012) A customized patch treatment for basal cell carcinoma completely destroys facial tumors without surgery or major radiation therapy in 80 percent of patients studied, say researchers at the Society of Nuclear Medicine's 2012 Annual Meeting. There are two main types of skin cancer:melanoma, which forms deep in the cells that produce pigment in skin, and nonmelanoma cancer, such as basal cell carcinoma and squamous cell carcinoma. Basal cell carcinoma is the most common type of skin cancer that affects the surface layer of the skin. Researchers have developed a treatment called a phosphorus-32 (P-32) skin patch, a radiation spot-treatment in the form of a patch that can safely and easily kill skin tumors with a few easy outpatient appointments. This therapy is ideal for patients with skin cancers that are very difficult to operate on, especially if skin grafting after surgery would be a challenge. "The study is important for the field of nuclear medicine as it opens a new dimension in the field of therapeutic nuclear medicine and dermatology, especially for the treatment of skin malignancies," says Priyanka Gupta, Ph.D., the lead of author of the study at All India Institute of Medical Sciences, New … Continue reading →
