10/23/2005 Milwaukee, WI Kawanza Newson Milwaukee Sentinel Jouranl (www.braneton.com) Byron Liebner is a sun lover, and he has several tiny scars to prove it. But it's the spot on his left forehead that he likes to talk about most. The skin there is dry and red, like a bad sunburn, and is a visual reminder of the high doses of radiation he receives each weekday to prevent his cancer from spreading into his eye. For the past five weeks, Liebner has had a mesh mask placed over his face to hold his head perfectly still and had his feet tied together to prevent wiggling so high-intensity radiation can be blasted into the nerve above his eye for 438 seconds. He's scheduled for seven weeks of radiation. "They have to be careful because it's a delicate situation," said Liebner, 84. "They told me I could lose clusters of hair in the back because the radiation goes right through the head," he said. "But I wouldn't care if I lost it because I don't have that much hair anyway." Surgery was not a feasible option for Liebner because his eyeball would have been removed, and he may have still needed radiation therapy later. Throughout the United States, cancer patients are benefiting from technological advancements that increase the precision of radiation treatment to the tumor while decreasing damage to the normal tissue or organs surrounding it. More precise treatment means patients can get higher doses of radiation over a shorter time span, and [...]

10/23/2005 Italy staff CancerConsultants.com According to an early on-line publication in the Journal of Clinical Oncology, a type of immunotherapy targeted against cancer cells appears to provide some anticancer responses in patients with advanced nasopharyngeal cancer that has stopped responding to radiation and chemotherapy. Nasopharyngeal carcinoma (NPC) is a type of head and neck cancer. Stage IV NPC refers to cancer that has spread from its site of origin and invaded nearby tissues or more distant areas of the body. Standard treatment for stage IV NPC typically includes radiation therapy and chemotherapy. However, a large portion of these patients will stop responding to these standard therapies and are left with very limited treatment options. NPC is a type of cancer that often appears related to infection with the Epstein-Barr virus (EBV). These cancer cells express specific antigens (proteins) on their surface associated with EBV. Immunotherapy is a type of therapy that stimulates the immune system to recognize and attack cancer cells within the body. Researchers have been evaluating ways in which to stimulate the immune system to recognize very specific antigens on cancer cells, such as the EBV antigens. Researchers from Italy recently conducted a small clinical trial to evaluate a type of immunotherapy for the treatment of 10 patients with advanced NPC that has stopped responding to chemotherapy and radiation therapy. Immunotherapy was used to stimulate the immune system to attack the cancer cells that displayed EBV antigens. Overall, the immunotherapy produced anticancer activity: 20% of patients experienced a [...]

10/18/2005 Gainesville, FL press release EurekAlert (ww.eurekalert.org) Some patients with head and neck cancer can be safely spared the risk and expense of surgery by undergoing a CT scan to predict whether the disease is in check after radiation therapy, according to study findings University of Florida doctors released today (Oct. 18) at the annual meeting of the American Society for Therapeutic Radiology and Oncology. Researchers with the UF Shands Cancer Center have identified criteria doctors can use to evaluate CT scans four weeks after patients undergo initial treatment. If these criteria are met, there is a 94 percent likelihood a patient's lymph nodes are cancer free, said Stanley L. Liauw, M.D., a resident in radiation oncology. Using a CT scan was found to be much more accurate than relying on a physical exam to assess response to treatment. Radiation therapy is commonly used to treat the more than 40,000 U.S. patients a year who develop advanced head and neck cancer. After radiation therapy, doctors often operate to remove affected lymph nodes. But UF physicians say in some cases surgery is unnecessary, and can increase recovery time, lead to infection and possibly compromise a patient's quality of life. The current study builds on previous research involving 95 head and neck cancer patients. In two-thirds of the patients who underwent surgery after radiotherapy, the removed lymph nodes turned out to be cancer free, noted UF radiologist Anthony Mancuso, M.D. Mancuso collaborated with UF radiation oncologists Robert Amdur, M.D., Christopher Morris, M.S., [...]

10/18/2005 Houston, TX staff Biocompare Life Science News (news.biocompare.com) Curcumin, the main ingredient of turmeric and the compound that gives curry its mustard-yellow color, inhibits metastasis to the lungs of mice with breast cancer, report researchers at The University of Texas M. D. Anderson Cancer Center. The study, to be published in the Oct. 15 issue of the journal Clinical Cancer Research, reports that the spice appears to shut down a protein active in the spread of breast cancer to a major target for metastasis. Though the study results are early, researchers found that the nontoxic natural substance not only repelled progression of the disease to the lungs, but also appeared to reverse the effects of paclitaxel (Taxol(tm)), a commonly prescribed chemotherapy for breast cancer that may trigger spread of the disease with use over a long period of time. Because Taxol is so toxic, it activates a protein that produces an inflammatory response that induces metastasis. Curcumin suppresses this response, making it impossible for the cancer to spread. In fact, researchers found that adding curcumin to Taxol actually enhances its effect. Curcumin breaks down the dose, making the therapy less toxic and just as powerful while delivering the same level of efficacy. "We are excited about the results of the study and the possible implications for taking the findings into the clinic in the next several years," says Bharat Aggarwal, Ph.D., professor of cancer medicine in M. D. Anderson's Department of Experimental Therapeutics. "At this time, advanced breast cancer [...]

10/18/2005 Mark El-Deiry, MD et al. Arch Otolaryngol Head Neck Surg. 2005;131:879-885 Objective: To compare the long-term, health-related quality-of-life outcomes in patients with advanced head and neck cancer (HNC) treated with surgery and postoperative radiation therapy (SRT) or concurrent chemotherapy and radiation therapy (CRT). Design: Matched-pair study comparing patients with advanced HNC treated with SRT or CRT at least 12 months after treatment. Patients completed 2 validated surveys addressing HNC-specific outcomes and depressive symptoms and provided information on employment and tobacco and alcohol use. Results for the 2 groups were compared using paired-sample t test and 2 analysis. Setting: University-based study. Patients: Patients with stage III or IV squamous cell carcinoma of the oropharynx, hypopharynx, and larynx who underwent SRT or received CRT. Main Outcome Measures: Head and neck cancer–specific health-related quality of life from the Head and Neck Cancer Inventory and level of depressive symptoms from the Beck Depression Inventory. Results: The matching process resulted in 27 patients in each treatment group. The HNC-specific domain scores (with higher scores representing better outcomes) for CRT vs SRT were eating, 37.8 vs 40.8 (P = .69); speech, 65.1 vs 56.0 (P = .23); aesthetics, 80.3 vs 69.2 (P = .14); and social disruption, 69.7 vs 70.6 (P = .90). Overall health-related quality of life was 64.0 with SRT and 55.0 with CRT (P = .142). For the Beck Depression Inventory (with higher scores representing worse outcomes), patients who underwent SRT had a mean score of 9.6 compared with 11.6 for patients [...]

10/18/2005 Denver, CO Robert Preidt Forbes (www.forbes.com) A new combination of radiation therapy and chemotherapy may offer a much greater chance of survival for head and neck cancer patients who develop a second tumor or whose disease recurs in an area that's already been treated with radiation, says a study by Canadian and American researchers. Few treatment options currently exist for these patients, according to background information from the study. This study included 99 patients who received split-course hyperfractionated radiation therapy twice a day for five days every two weeks for four cycles. The patients also received chemotherapy with cisplatin (daily every two weeks for four cycles) and paclitaxel (daily every two weeks for four cycles). The median follow-up for surviving patients was 23.6 months and the median survival was 12.1 months. The median survival for patients treated with the current standard of chemotherapy alone is six to eight months, and one-year survival rates are typically less than 35 percent, the researchers said. Fifty percent of the patients in this study survived for at least a year while 26 percent survived two years. The findings were presented Monday at the American Society for Therapeutic Radiology and Oncology annual meeting, in Denver. "The side effects from this experimental regimen were significant, but these patients were among those with the most serious cancers," Dr. Eric Horwitz, study co-principal investigator and clinical director in the radiation oncology department at Fox Chase Cancer Center in Philadelphia, said in a prepared statement. Eight of the [...]

10/18/2005 Louisville, CO press release PRNewswire (www.prnewswire.com) RxKinetix, Inc., a specialty pharmaceutical company developing new therapeutics focused in oncology care, today announced completion of their Phase 2 clinical trial of RK-0202 in oral mucositis. The Independent Data Monitoring Committee (IDMC) for the Phase 2 trial recommended stopping enrollment in order to expedite development of the drug. The IDMC found no significant safety issues associated with the use of RK-0202. The Phase 2 trial was double-blind, randomized and placebo controlled, 114 out of a planned total of 130 patients receiving radiotherapy for head and neck cancer were enrolled. The preliminary data at 50 Gy cumulative radiation shows that, compared with placebo, RK-0202 showed a 32% reduction in the incidence of WHO Grade mucositis greater than or equal to 3, which is a measure of the patient's inability to eat solid food. Furthermore, the percentage of patients requiring nutritional support via external feeding tubes was 21% in the placebo group compared with 3% in the group taking RK-0202. "We were delighted to receive this recommendation to conclude our Phase 2 trial for RK-0202 in oral mucositis," said Harry Ross, M.D., CEO and President of RxKinetix, Inc. "These results provide a strong signal for RK-0202 against oral mucositis allowing us to move forward with our goal of achieving a safe and effective treatment for this debilitating disorder." The Company will now complete the data gathering for the remaining patients who were active at the time of the IDMC review and move forward with [...]

10/18/2005 Houston, TX Bradley A. Schiff, MD et al. Arch Otolaryngol Head Neck Surg. 2005;131:874-878 Objectives: To assess the role of selective neck dissection in patients with squamous cell carcinoma (SCC) of the oral tongue with advanced nodal disease, and to assess the role of postoperative radiotherapy in patients with SCC of the oral tongue with pathologically N1 necks. Design: Retrospective study of the medical records of all patients who underwent neck dissection for SCC of the oral tongue from January 1, 1980, to December 31, 1995. Median follow-up was 5.7 years. Setting: The University of Texas M. D. Anderson Cancer Center, Houston, a tertiary care cancer hospital. Patients: A total of 220 patients with SCC of the oral tongue who received surgical treatment of both the primary tumor and the neck and who had an identifiable type of neck dissection, no synchronous or metachronous lesions, and no evidence of local recurrence. Interventions: All patients underwent resection of the primary tumor and neck dissection. The extent of neck dissection was determined by surgeon preference. Some patients received radiotherapy to the neck as well. Main Outcome Measures: Clinical and pathological nodal status, type of neck dissection, and use of radiotherapy. The end points evaluated included the regional control rates. Results: For clinically N+ patients, 5 of 45 treated with selective neck dissection and 1 of 19 treated with radical or modified radical neck dissection had recurrences in the ipsilateral neck. If only patients with significant tumor burden on final pathological examination [...]

10/17/2005 Denver, CO press release PharmaLive (www.medadnews.com) ImClone Systems Incorporated today announced the launch of a first-of-its-kind, independent national registry of patients with head and neck cancer known as LORHAN (Longitudinal Oncology Registry of Head And Neck carcinoma) at the 2005 American Society of Therapeutic Radiology and Oncology (ASTRO) Annual Meeting in Denver. LORHAN will gather together detailed information, including treatment and supportive care choices as well as recurrence and survival outcomes, into a national database via a confidential Web-based system. The registry will then allow physicians participating in the registry to compare the treatment outcomes of their patients to a national database. LORHAN will also determine whether the results of treatment-changing clinical studies are being incorporated effectively into daily practice, and compare treatment practices in community and academic settings. An estimated 26,400 patients will be eligible to enter the system each year, of which approximately 1,000 are expected to be enrolled. The American Board of Internal Medicine (ABIM) has approved use of LORHAN for medical oncologists wishing to satisfy a part of their re-certification related to practice performance. ABIM Certification is designed to assure the public that a medical specialist possesses the knowledge, experience, and skills requisite to the provision of high quality patient care. "This registry is unique in that it is the first time that the overall management of head and neck cancer will be tracked across academic centers and community settings," said Eric K. Rowinsky, M.D., Senior Vice President and Chief Medical Officer of ImClone Systems. [...]

10/17/2005 London, England staff BBC News (news.bbc.co.uk) An invention that helps throat cancer patients to speak has won first prize at the national NHS Innovation Awards. The Sunderland Air Pressure Meter allows doctors to choose the right prosthetic speech valve for patients who have had their larynx removed. Until this breakthrough, speech and language therapists relied on trial and error to select the right valve. The meter was developed by Regional Medical Physics Department (RMPD) staff based at Sunderland Royal Hospital. 'Monitor progress' The device is the result of five years of research and development, and will now be sold to hospitals around the country. It beat 17 other regional finalists to the award, which will be presented to consultant medical physicist who led the RMPD team, Bill Allan, by the Health Minister responsible for innovation, on Monday. Mr Allan said: "The valves are used by the speech and language therapists on patients who have had a total laryngectomy. "Using modern technology, we can put a small prosthetic valve in the oesophagus that allows them to speak. "Our device measures the air pressure and helps choose a valve that is right for the patient. It also helps us monitor a patient's progress."
