GSK partners with Enigma, Abbott on cancer immunotherapy project

Source: bioopticsworld.co Author: staff Pharmaceuticals company, Abbott (Des Plaines, IL), announced an agreement with GSK to develop an automated molecular diagnostic test, also based on RT-PCR technology, to screen non-small cell lung cancer (NSCLC) tumors for expression of the MAGE-A3 antigen. GSK's MAGE-A3 ASCI (antigen specific cancer immunotherapy) candidate is currently being evaluated as an adjuvant treatment in resected NSCLC in the Phase III clinical study MAGRIT, the largest lung cancer treatment study ever conducted. Fast, accurate influenza testing The GSK-Enigma partnership aims for joint development of the Enigma ML (mini laboratory) PCR platform to deliver fully-automated results from swab samples in less than 60 minutes at the point of care--to the same accuracy standards as reference laboratories. Thus, patients can be tested for specific influenza subtypes and quickly receive appropriate treatment. Operators of the Enigma ML system will not require specialist training. A trial involving working prototypes of the ML system with front line health care providers across Europe is planned for Q4 2009. Launch of Enigma ML is anticipated in early 2011, subject to successful clinical trials and regulatory approval. Cancer immunotherapy Under terms of the GSK-Abbott agreement, the partners will develop and commercialize an RT-PCR test--designed to detect MAGE A3--for use on the Abbott m2000 automated instrument system. "This is an exciting collaboration with a leading company in cancer immunotherapy research," said Stafford O'Kelly, head of Abbott's molecular diagnostics business. "The agreement is indicative of our focus on personalized medicine and developing analytical molecular tools to identify [...]

Oral spray reduces mouth sores

Source: patient.cancerconsultants.com Author: staff Among patients treated with radiation therapy for head and neck cancer, mouth sores (oral mucositis) were reduced by use of an oral spray containing epidermal growth factor (EGF). These results were published in Cancer. Mouth sores are one of the most common and serious complications of radiation therapy for head and neck cancer. Mouth sores are painful, interfere with eating and drinking, and can also lead to infection. If they become severe enough they may require a reduction or delay in cancer treatment. Epidermal growth factor (EGF) is a protein that plays several important roles in the body, including wound healing and tissue growth. To evaluate the use of an EGF-containing oral spray for the treatment of mouth sores, researchers in Korea conducted a Phase II clinical trial among 113 patients with head and neck cancer. The most common sites of cancer among the study participants were the nasopharynx, oropharynx, and oral cavity. All of the patients were treated with radiation therapy with or without chemotherapy. In addition, patients were assigned to receive one of three doses of the EGF oral spray or a placebo. The spray was used twice a day through week five of radiation therapy. Patients were considered to have responded to the EGF spray or placebo if they had no mucositis or only mild mucositis at weeks 4 and 5 of radiation therapy. Response rate among patients in the placebo group was 37%. Response rates among patients in the EGF spray groups [...]

Laser microsurgery for tongue cancer is as effective as invasive open surgery, according to new study

Source: www.sciencedaily.com Author: press release Transoral (through-the-mouth) laser surgery to remove cancer at the base of the tongue is as effective as more invasive open surgery and may improve quality of life according to a new study by Rush University Medical Center. The study is published in the July issue of the scientific journal Otolaryngology –Head and Neck Surgery. The study involved a retrospective chart review of 71 patients who underwent transoral laser microsurgery for squamous cell carcinoma of the base of the tongue. At 24 months, overall survival was 90 percent and disease specific survival was 94 percent. Quality-of-life data, obtained for 46 patients, revealed the majority had mild or no pain, minimally impaired to normal swallowing, and normal speech. Historically, the tongue base could only be safely accessed through complicated open surgical approaches through the neck. Delicate structures in the neck, such as the voice box, the trachea, the esophagus, lymph nodes, muscles and large nerves make surgical resection difficult with significant complications including speech and swallowing impairment. Advances in transoral laser microsurgery have transformed the surgeon's ability to treat cancer that was not otherwise amenable to surgical therapy. The surgery is performed through the opening of the mouth using an endoscope with a lighted camera and microscopic lens to view the area. Using a CO-2 laser and micro-staging, surgeons carefully remove the tumor in small pieces minimizing disruption to nearby tissues, thereby reducing complications and the likelihood of infections. With magnification of normal and abnormal tissue the [...]

Beastie Boy, Adam Yauch announces he has cancer of the salivary gland

Source: Newsday.com Author: Staff The Beastie Boys have cancelled all their upcoming tour dates, including their headlining spot at the All Points West Festival next week, and pushed back their "Hot Sauce Committee Part 1" album, after Adam Yauch was diagnosed with cancer of the salivary gland. In a video statement (below) released this morning, Yauch said the cancer is treatable and will not affect his voice. He will have surgery next week to remove the tumor and will need several weeks of further treatment. "It's a pain in the neck (sorry had to say it) because I was really looking forward to playing these shows, but the doctors have made it clear that this is not the kind of thing that can be put aside to deal with later," Yauch said in a statement. No word yet from All Points West organizers on how the cancellation will be handled.

Stopping oral cancer in its tracks

Source: insciences.org Author: staff In new research from Boston University Henry M. Goldman School of Dental Medicine (GSDM), Dr. Maria Kukuruzinska and her team are the first to show, in vivo, a direct relationship between expression of the gene DPAGT1 and tumor spread in oral cancer. “When the gene is highly expressed in oral squamous cell carcinoma, it drives cellular discohesion and tumor spread within the oral cavity,” explains Dr. Kukuruzinska, Professor of Molecular and Cell Biology at GSDM. Researchers found that overexpression of DPAGT1, the gene that determines glycosylation capacity, led to abnormal glycosylation of e-cadherin, causing it to malfunction as a cell-cell adhesion receptor and tumor suppressor. When researchers suppressed the gene using oral cancer cell lines, cancer spread was interrupted. The findings suggest the potential to stop or reverse oral cancer tumor growth by therapeutically regulating DPAGT1. Researchers plan to find what causes overexpression of DPAGT1 in cancer and hope to find the key repressor molecule to regulate the gene. Unlike many cancers, which metastasize early, oral cancer forms massive tumors and generally stays in the mouth. One of the deadliest cancer diagnoses, the current survival rate is about five years. Notes: 1. Dr. Kukuruzinska worked with Dr. Mihai Nita-Lazar, Research Associate in the Department of Molecular and Cell Biology; Dr. Vikki Noonan, formerly of the Department of Oral Pathology; Drs. A. Sue Menko and Janice Walker of the Department of Anatomy, Pathology, and Cell Biology at Thomas Jefferson University; and Dr. Ivan Rebustini of the National [...]

Moderate alcohol intake and cancer incidence in women

Source: www.medscape.com Authors: Naomi E. Allen et al. Background: With the exception of breast cancer, little is known about the effect of moderate intakes of alcohol, or of particular types of alcohol, on cancer risk in women. Methods: A total of 1 280 296 middle-aged women in the United Kingdom enrolled in the Million Women Study were routinely followed for incident cancer. Cox regression models were used to calculate adjusted relative risks and 95% confidence intervals (CIs) for 21 site-specific cancers according to amount and type of alcoholic beverage consumed. All statistical tests were two-sided. Results: A quarter of the cohort reported drinking no alcohol; 98% of drinkers consumed fewer than 21 drinks per week, with drinkers consuming an average of 10 g alcohol (1 drink) per day. During an average 7.2 years of follow-up per woman 68 775 invasive cancers occurred. Increasing alcohol consumption was associated with increased risks of cancers of the oral cavity and pharynx (increase per 10 g/d = 29%, 95% CI = 14% to 45%, P trend

In push for cancer screening, limited benefits

Source: nytimes.com Author: Natasha Singer "Don’t forget to check your neck,” says an advertising campaign encouraging people to visit doctors for exams to detect thyroid cancer. In another cancer awareness effort, Representative Debbie Wasserman Schultz, a Florida Democrat, has more than 350 House co-sponsors for her bill to promote the early detection of breast cancer in young women, teaching them about screening methods like self-exams and genetic testing. Meanwhile, the foundation of the American Urological Association has a prostate cancer awareness campaign starring Hall of Fame football players. “Get screened,” Len Dawson, a former Kansas City Chiefs quarterback, says in a public service television spot. “Don’t let prostate cancer take you out of the game.” Nearly every body part susceptible to cancer now has an advocacy group, politician or athlete with a public awareness campaign to promote routine screening tests — even though it is well established that many of these exams offer little benefit for the general public. An upshot of the decades-long war on cancer is the popular belief that healthy people should regularly examine their bodies or undergo screening because early detection saves lives. But in fact, except for a few types of cancer, routine screening has not been proven to reduce the death toll from cancer for people without specific symptoms or risk factors — like a breast lump or a family history of cancer — and could even lead to harm, many experts on health say. That is why the continued rollout of screening campaigns, [...]

Israeli study sees link between oral cancer, cell phones

Source: haaretz.com Author: Dan Even A recent study documents a sharp rise in the incidence of salivary gland cancer in Israel that researchers believe may be linked to the use of mobile phones. The study was commissioned by the Israel Dental Association and directed by Avi Zini of the community dentistry department at the Hebrew University-Hadassah School of Dental Medicine. The study included examination of the incidence of oral cavity cancers in Israel from 1970 to 2006. Among salivary gland cancer cases, researchers found a worrying rise in the number of cases of malignant growth in parotid glands - the salivary gland located under the ear, near the location where cell phones are held during conversations. By contrast, the incidence of salivary cancers in glands of the lower mouth - the so-called submandular and sublingual salivary glands - remained stable. From 1980-2002 the number of cases of parotid salivary cancer held steady at around 25 per year. The number of cases rose dramatically in the five years after to 70 cases per year. "We haven't gathered data on the use of cell phones on the part of the patients," Zini said, "but the rise [in cancer cases] absolutely could indicate increased exposure to cellular telephones and damage caused by radiation." The researchers intend to collect data on their oral cancer patients' cell phone use during the next stage of the study to examine the possible statistical link between the two. Of the 11,843 Israelis who developed oral cancers during the [...]
