Ultrasonography-guided fine-needle aspiration for the assessment of cervical metastases

Source: Arch Otolaryngol Head Neck Surg. 2000;126:1091-1096 Authors: Marco Knappe, MD et al. Objective: To assess the value of ultrasonography (US) combined with fine-needle aspiration (FNA) cytology for the investigation of lymph node metastases in patients with head and neck cancer. Design: Comparison of clinical examination (palpation) and preoperative US-FNA examination results of cervical nodes in a sample of patients with head and neck cancer. The histological features of the neck dissection specimens are used to validate these 2 variables. Setting: A head and neck oncology service in a tertiary referral hospital. Patients: A consecutive sample of 56 patients with head and neck squamous cell carcinoma, first seen between April 1, 1996, and July 30, 1998, who had neck dissections performed after the US-FNA examination. Intervention: Cervical US-FNA preoperatively, followed by elective or therapeutic radical modified or selective neck dissection. Main Outcome Measures: The histological examination results of subsequent neck dissection specimens are used to determine the sensitivity, specificity, and accuracy of US-FNA for individual nodes. Second, the results of node staging by clinical examination and US-FNA examination are compared. Results: The sensitivity was 89.2%; specificity, 98.1%; and accuracy, 94.5%. Correct node stages were obtained in 52 (93%) of the patients using US-FNA compared with 34 (61%) using palpation. Conclusions: Ultrasonography combined with FNA is a highly accurate technique for the investigation of cervical lymph node metastases. A more accurate diagnosis may result in more appropriate treatment, particularly in a setting with limited resources. Retropharyngeal nodes, micrometastases, and lymph nodes [...]

Head, neck cancer treatment often not completed

Source: www.ajc.com/health Author: staff Incomplete and interrupted radiation treatment is a common problem among Medicare patients with head and neck cancer, a new study has found. Researchers analyzed data from 5,086 Medicare patients diagnosed with head and neck cancer between 1997 and 2003 and found that nearly 40 percent of them experienced interruptions in radiation therapy or failed to complete the course of therapy. People who had surgery before radiation treatment were more likely to complete the treatment without interruption than were those who did not have surgery (70 percent versus 52 percent). People with co-existing illnesses, those who had undergone chemotherapy and those whose disease had spread to surrounding lymph nodes were less likely to do so, the study found. The findings are in the September issue of Archives of Otolaryngology -- Head & Neck Surgery. "Surgical patients may be more likely to complete radiotherapy for several reasons," wrote Megan Dann Fesinmeyer, of the Fred Hutchinson Cancer Research Center in Seattle, and her research colleagues. "First, characteristics that make patients good candidates for surgery may also make them more likely to complete radiotherapy. Because comorbidities are known to decrease survival in patients with head and neck cancer, healthier patients may be chosen by surgeons to complete more rigorous treatments (e.g., surgery in addition to radiotherapy)." The study authors added that people "willing to undergo major surgery to treat their disease may also be more motivated to complete a full course of uninterrupted radiation therapy, despite any toxic effects of [...]

Speaking, eating possible after tonsil cancer surgery with reconstruction

Source: www.eurekalert.org Author: press release A new technique for reconstructing the palate after surgery for tonsil cancer maintained patients' ability to speak clearly and eat most foods, a new study shows. The technique, developed at the University of Michigan Comprehensive Cancer Center, is described in the September Archives of Otolaryngology – Head & Neck Surgery. "This is the area that triggers swallowing, that separates the mouth from the nasal cavity. It affects speech and eating – typically, patients have difficulty eating when they have this kind of tumor and undergo surgery. We can remove the cancer, but there are major quality of life issues," says study author Douglas Chepeha, M.D., M.S.P.H., associate professor of otolaryngology head and neck surgery and director of the microvascular program at the University of Michigan Health System. Tonsil cancer develops in the back of the throat, which means surgery could include parts of the palate, the tongue and the jaw. Traditional reconstruction efforts have meant taking a large, round piece of tissue to plug the hole left when the tumor is removed. But this impairs the way the palate and tongue function, and does not restore the complex components of the throat that allow a person to speak and swallow. With the new technique, surgeons first create a tube from the remaining palate by attaching the palate to the back part of the throat, next to where the tumor was removed. This tube separates the mouth from the nasal cavity and closes during swallowing, allowing [...]

Smoking ban heart gains ‘massive’

Source: news.bbc.co.uk Author: staff Bans on smoking in public places have had a bigger impact on preventing heart attacks than ever expected, data shows. Smoking bans cut the number of heart attacks in Europe and North America by up to a third, two studies report. This "heart gain" is far greater than both originally anticipated and the 10% figure recently quoted by England's Department of Health. The studies appear in two leading journals - Circulation and the Journal of the American College of Cardiology. Heart attacks in the UK alone affect an estimated 275,000 people and kill 146,000 each year. Big impact Earlier this month it was announced that heart attack rates fell by about 10% in England in the year after the ban on smoking in public places was introduced in July 2007 - which is more than originally anticipated. But the latest work, based on the results of numerous different studies collectively involving millions of people, indicated that smoking bans have reduced heart attack rates by as much as 26% per year. Second-hand smoke is thought to increase the chances of a heart attack by making the blood more prone to clotting, reducing levels of beneficial "good" cholesterol, and raising the risk of dangerous heart rhythms. Dr James Lightwood, of the University of California at San Francisco, led the Circulation study that pooled together 13 separate analyses. His team found that heart attack rates across Europe and North America started to drop immediately following implementation of anti-smoking laws, [...]

BioVex Agrees SPA With the FDA for a Pivotal Phase III Study With OncoVEX (GM-CSF) in Head and Neck Cancer

Source: PR Newswire Author: Staff WOBURN, Mass., Sept. 15 /PRNewswire/ -- BioVex Inc, a biotechnology company developing clinical stage treatments for cancer and the prevention of infectious disease, announced today that the U.S. Food and Drug Administration (FDA) has approved the design of a single, pivotal, Phase III clinical trial evaluating its lead product, OncoVEX (GM-CSF), for the first-line treatment of patients with squamous cell cancer of the head and neck. The study is the second the Company has agreed with the FDA under the Special Protocol Assessment (SPA) procedure and highlights the broad potential utility of BioVex's first-in-class cancer destroying virus technology. The first SPA was in melanoma under which BioVex is currently conducting a pivotal Phase III trial. Patients with head and neck cancer often present with locally advanced, bulky disease that is too large, or too close, to vital organs to remove surgically. These patients typically undergo combination radiation and chemotherapy treatment, in some cases with additional surgery. Patients who present with tumor-containing lymph nodes are particularly difficult to treat and approximately half of these patients relapse within two years. Philip Astley-Sparke, President & CEO, for BioVex said: "The announcement of our second SPA governing a Phase III study demonstrates the breadth of the commercial opportunity with OncoVEX (GM-CSF). In addition to treating metastatic disease as is the intention in our ongoing Phase 3 study in melanoma, following multiple systemic responses in Phase II, OncoVEX (GM-CSF) also has considerable potential utility in treating discrete solid tumor masses [...]

Where cancer progress is rare, one man says no

Source: nytimes.com Author: Gardiner Harris Politicians and researchers have predicted for nearly four decades that a cure for cancer is near, but cancer death rates have hardly budged and most new cancer drugs cost a fortune while giving patients few, if any, added weeks of life. For this collective failure, the man atop the nation’s regulatory agency for new cancer drugs increasingly — and supporters say unfairly — gets the blame: Dr. Richard Pazdur. Patient advocates have called Dr. Pazdur, director of the Food and Drug Administration’s cancer drug office, a murderer, conservative pundits have vilified him as an obstructionist bureaucrat, and guards are now posted at the agency’s public cancer advisory meetings to protect him and other committee members. “The industry is not producing that many good drugs, so now they’re looking for scapegoats in Rick Pazdur and the F.D.A.,” said Ira S. Loss, who follows the drug industry for Washington Analysis, a service for investors. In 10 years at the Food and Drug Administration, Dr. Pazdur, 57, has helped to loosen approval standards for cancer medicines and made it easier for dying patients to get experimental drugs. But he demands that drug makers prove with near certainty that their products are beneficial, a requirement that he repeated at a public advisory hearing on Sept. 1 in the slow, loud tones of someone disciplining a dog. After he spoke, the committee of experts voted to reject both drugs. Critics say that Dr. Pazdur’s resolve has cost thousands of lives [...]

Going up in smoke

Source: www.abs-cbnnews.com (Philippines) Author: Adel Gabot Who would have thought graphic, disturbing pictures, like those showing a dead fetus lying amidst cigarette butts, or gangrenous feet, or ugly, bleeding mouth sores, or throats bulging with massive red tumors or black lung tissue would be so widely distributed, and even legally mandated? I’m talking about cigarette packaging, of course. Those of you smokers who travel have seen these pictures on cigarette packs abroad. In Singapore, Thailand, Malaysia, Australia, New Zealand, Brazil, everywhere. These caring and enlightened governments have long ago made it a law that cigarettes packaging must carry graphic images of diseases and the effects of tobacco on our health, in an aggressive effort to scare people off smoking. The more graphic the pictures, the better to convince people to kick the habit. Canada, which started doing this in 2000 with a picture of mouth cancer, is now contemplating upping the ante by putting the actual deathbed photos of anti-smoking activist Barb Tarbox, as she looked, emaciated, and withered just before her recent death from cancer. Their research has shown that the photos elicit an even more intense response from smokers than the usual diseased body parts. More recently, the United States, which had limited health warnings on cigarette packaging to a short, small text-only message from the Surgeon General on the side of the box, is now about to implement similar graphic pictorial warnings on 50% of the front and back of the pack. President Barack Obama, who is [...]

UCLA awarded Government grant to extended oral cancer research

Source: Privatemdlabs.com Author: Brendan Missett Funding made available from the Obama Administration's stimulus plan will assist the UCLA School of Dentistry in cancer research. The National Institutes of Health awarded more than $5 million to UCLA which will be used toward the construction of a state-of-the-art complex designed to expand the School of Dentistry's research on the detection and treatment of oral cancer. The building will be called the Yip Center for Oral/Head & Neck Oncology Research. In the past three years, the school was awarded close to $30 million in grants for oral cancer research. Construction plans for the complex, which is named after philanthropists Felix and Mildred Yip, have already begun. The construction is expected to conclude in 2013. No-Hee Park, dean of the UCLA School of Dentistry, commented, "This visionary funding will enable the dental school to become a nexus of multidisciplinary, collaborative research." She added that she hopes the school will become the "premier" oral cancer research program in the country. According to the Oral Cancer Foundation, oral cancer kills about one person every hour, and only half of oral cancer patients survive for more than 5 years after their diagnosis. The National Cancer Institute recommends oral cancer testing to detect the disease at an early, treatable stage.
