7/17/2006 Fort Worth, TX Bob Ray Sanders StarTelegram.com A 75-year-old Fort Worth man is the Billy Graham of the anti-smoking crusade. When Jerry Berkowitz finishes talking to schoolchildren, they start coming down the aisles to testify -- to ask questions and, in some cases, to give him something he gave up 25 years ago. At his home the other day, he recalled his first speech. It was to more than 300 students at Aledo Middle School. The youngsters were seated on the gymnasium floor, and as Berkowitz prepared to address them, he remembered administrators' warnings that the kids likely would be a little restless, partly because it was the last period of the day. But as soon as he began to speak, sounding somewhat like a robot from a science fiction movie, the kids were mesmerized, he said. At the end of his 25-minute presentation, "a little kid about this tall [just over waist high] handed me a pack of Marlboros and said, 'Hey, mister, take this away from me. I'll never smoke again, I promise.' " Soon afterward at a similar event, a young girl approached him. He had noticed her on the front row, staring straight at him during the entire speech. The girl was deaf, Berkowitz learned, and she had been reading his lips. "She handed me a brand of cigarettes I had never seen before and said, 'I've been trying to quit for years.' And I burst out crying," Berkowitz said as tears welled in his [...]

7/17/2006 Long Beach, CA Phillip Zonkel Long Beach PressTelegram.com Sabrina Mansfield is receiving her final hyperthermia treatment a therapy designed to kill her aggressive and recurrent cancer. She has seven catheters in her neck and head. Each one beams microwave energy to heat a precise location of her cancer-riddled tissue. When this heating is combined with radiation or chemotherapy, it increases the success rate of these therapies for eradicating cancer cells, according to recent research. "We needed to be extremely aggressive with Sabrina's treatment," says Dr. Behrooz Hakimian, Mansfield's radiation oncologist at Cedars-Sinai Medical Center, who recommended the combination therapy. "She probably had one chance of treatment at this point. I wanted her to have the best treatment." Mansfield received her treatment from Dr. Nisar Syed, director of radiation oncology at Long Beach Memorial Medical Center, who is considered a leader in the field of hyperthermia. Syed has been administering the procedure for more than 22 years and has treated more than 3,000 patients. Of Syed's patients, he says approximately 25 percent had recurrent cancer after treatment. "Dr. Syed has the most experience in Southern California, if not on the West Coast, in using hyperthermia," Hakimian says. "He's magical with his hands." Hyperthermia works on selected cancers: head and neck, tongue, throat, cervix, prostate, melanoma, sarcoma and breast cancer on the chest wall. They can be locally advanced tumors that have not metastasized or recurrent cancers that have been treated with surgery, chemotherapy and/or radiation. Sixty-five percent of Syed's patients [...]

7/15/2006 Viena, Austria Clemens Klug et al. Laryngoscope, July 1, 2006; 116(7): 1162-1167 Objective/Hypotheses: The aim of this retrospective cohort study was to investigate the effect of prior radiotherapy (XRT) on the outcome of microvascular free tissue transfer in the head and neck region. Methods: Four hundred fifty-five patients, subdivided into three groups, were analyzed. Groups I (no previous XRT, n = 110), II (previous radiochemotherapy with 50 Gy focus dosage in the primary treatment regime for oral cancer, n = 322), and III (secondary reconstruction after XRT-induced complications, n = 23) were compared regarding flap success rate, postoperative complications, postoperative mortality, duration of intensive care (DOIC), and hospitalization (DOH). Results: Flap success did not differ significantly across groups (I: 95.5%, II: 93.2%, III: 91.3%. Risk of postoperative complications was significantly lower for group I (12.7%) compared with groups II (23.9%) and III (39.1%). DOIC and DOH were significantly shorter for patients in group I than for those in groups II and III. Conclusions: XRT before free tissue transfer does not significantly increase flap loss or postoperative mortality but does increase postoperative complications and length of hospitalization.

7/15/2006 Mississauga, Ontario, Canada IC Munro et al. J Esthet Restor Dent, January 1, 2006; 18(3): 119-25 Tooth whitening products containing hydrogen peroxide or carbamide peroxide were evaluated in this review for potential oral cancer risk from their use. Hydrogen peroxide is genotoxic in vitro, but not in vivo. Hydrogen peroxide was not considered to pose a genotoxic risk to humans. The animal toxicology data relevant to the assessment of the carcinogenicity of hydrogen peroxide do not indicate that it has significant carcinogenic activity at any site, including the oral cavity. Hydrogen peroxide was found to enhance the carcinogenic effects of potent DNA reactive carcinogens in experimental animals. However, these experimental conditions are artificial as they are related to high exposures and are of no relevance to potential human exposures to low quantities of hydrogen peroxide from the use of tooth whitening products. Clinical data on hydrogen peroxide-containing tooth whitening products show no evidence for the development of preneoplastic or neoplastic oral lesions. Exposures to hydrogen peroxide received by the oral cavity are exceedingly low, of short duration (30-60 minutes), and could not plausibly enhance any carcinogenic risk associated with exposure of the oral cavity to chemicals in cigarette smoke or to alcohol, both known risk factors for the development of oral cancer. Based on a comprehensive review of the available literature and research, the use of tooth whitening products containing hydrogen peroxide or carbamide peroxide does not appear to pose an increased risk of oral cancer in the general [...]

7/15/2006 Baltimore, MD Karl B. Hille Examiner.com A possible cure for some types of mouth, larynx and throat cancer is being tested at the University of Maryland Medical Center. University researchers have begun testing “Trojan peptide” vaccines to treat squamous cell carcinoma, a common type of head and neck cancer. The vaccine targets specific proteins made by tumors, and in theory can stimulate the body’s immune system to destroy the cancer. “It’s really founded on very strong science,” said Dr. Scott Strome, who developed the vaccine and stands to benefit if it becomes an approved treatment. Currently, researchers are accepting patients for Phase I trials, which test the safety of a new therapy. If it proves safe, further trials will test the effectiveness of the vaccine. Strome said the vaccine is experimental and it is not known yet if it will reduce or eliminate patients’ tumors. Researchers hope the vaccine therapy will improve the survival rate and quality of life for patients. Cancers of the head and neck — including those of the throat, mouth, voice box, sinuses, salivary glands and skin — are often difficult to treat and have a high risk of recurrence, according to information provided by the University of Maryland. Treatments include surgery, chemotherapy and radiation therapy. Much larger than traditional vaccine molecules, these peptides contain approximately 40 to 50 amino acids, Strome said. Researchers believe these larger peptides may trigger a stronger, two-pronged response by the body’s immune system. The vaccines prepare white blood cells [...]

7/15/2006 Sao Paolo, Brazil L. Cuffari et al. Oral Surg Oral Med Oral Pathol Oral Radiol Endod, July 1, 2006; 102(1): 56-61 OBJECTIVE: To identify pain as the initial symptom of oral cancer patients. STUDY DESIGN: Hospital charts of 1412 patients (1977 to 1998) with oral cancer were reviewed (238 female and 1174 male). Results: Pain was the initial complaint in 19.2% of the sample. Oral cancer (ratio 4:1) and initial pain (ratio 9:1; P= .001) was prevalent in men. There were 12 different complaints of pain: sore throat (37.6%), tongue pain (14.0%), mouth pain (12.9%); pain when swallowing (11.1%), dental pain (5.9%); earache (5.9%); pain in the palate (4.1%); burning mouth (3.3%); gingival pain (2.2%); pain when chewing (1.1%); neck pain (1.1%), and facial pain (0.7%). Pain was associated with advanced TNM staging and location of tumor in the tongue (P= .004) and the tongue/mouth floor (P< .006). Conclusion: There were 12 different descriptions of pain; pain was related to TNM staging in the tongue and the tongue/mouth floor. The data presented reinforce the suggestion that patients with orofacial pain need systematized evaluation and sometimes require an interdisciplinary approach.

7/15/2006 Iowa City, IA staff CancerConsultants.com The American Society of Clinical Oncology recently published guidelines about larynx preservation in patients with laryngeal cancer. The guidelines note the importance of balancing successful cancer treatment with patient function and quality of life. Head and neck cancers originate in the throat, larynx (voice box), pharynx, salivary glands, or oral cavity (lip, mouth, tongue). Most head and neck cancers involve squamous cells, which are cells that line the mouth, throat, or other structures. For patients facing the treatment of laryngeal cancer, an important consideration is whether the larynx can be preserved. Because the larynx is involved in speech and communication, complete removal of the larynx can have a dramatic and adverse effect on a patient’s life. Treatment approaches that preserve the larynx include radiation therapy alone, chemotherapy plus radiation therapy, and surgery that preserves the function of the larynx. Certain patients, however, may not be candidates for these approaches, and may require more extensive treatment. To guide the use of larynx-preservation approaches, the American Society of Clinical Oncology summarized the available evidence and released recommendations. Final decisions about treatment, however, will still require consideration of each patient’s individual circumstances. - For patients with limited laryngeal cancer (T1 or T2), the recommendations note that patients should initially be treated with the intent to preserve the larynx. In these patients, radiation therapy alone or larynx-preservation surgery each appear to produce similar survival outcomes. The recommendations include the qualification that “Limited-stage laryngeal cancer constitutes a wide spectrum [...]

7/15/2006 Queensland, Australia D Chin et al. Expert Rev Anticancer Ther, July 1, 2006; 6(7): 1111-8 Head and neck cancer consists of a diverse group of cancers that ranges from cutaneous, lip, salivary glands, sinuses, oral cavity, pharynx and larynx. Each group dictates different management. In this review, the primary focus is on head and neck squamous cell carcinoma (HNSCC) arising from the mucosal lining of the oral cavity and pharynx, excluding nasopharyngeal cancer. Presently, HNSCC is the sixth most prevalent neoplasm in the world, with approximately 900,000 cases diagnosed worldwide. Prognosis has improved little in the past 30 years. In those who have survived, pain, disfigurement and physical disability from treatment have had an enormous psychosocial impact on their lives. Management of these patients remains a challenge, especially in developing countries where this disease is most common. Of all human cancers, HNSCC is the most distressing since the head and neck is the site of the most complex functional anatomy in the human body. Its areas of responsibility include breathing, the CNS, vision, hearing, balance, olfaction, taste, swallowing, voice, endocrine and cosmesis. Cancers that occur in this area impact on these important human functions. Consequently, in treating cancers of the head and neck, the effects of the treatment on the functional outcome of the patient need the most serious consideration. In assessing the success of HNSCC treatment, consideration of both the survival and functional deficits that the patient may suffer as a consequence of their treatment are of paramount [...]

7/11/2006 Rochester, MN staff www.biocompare.com Researchers at the University of Minnesota have developed novel anti-cancer drugs to treat solid tumors. These "small molecules" belong to a class of pharmaceutical agents called anti-angiogenics. The new compounds are a refined form of drugs that effectively reduce blood flow to the tumor, thereby inhibiting tumor growth. The results of the study appear in the July 5 issue of the Journal of the National Cancer Institute. "This is a novel class of drugs that increases the potential for good, effective treatment for cancer patients with tumors," said Kevin Mayo, Ph.D., principle investigator and professor of biochemistry, molecular biology and biophysics at the University of Minnesota Medical School. There is currently a protein anti-angiogenic agent approved by the FDA for clinical use. These new tumor-targeting compounds were designed to mimic the functional part of an anti-angiogenic protein. But, because the compounds are not proteins themselves, they have the advantage of possibly being taken in pill form and being less costly to produce. In animal studies with mice, the compounds inhibited tumor growth by up to 80 percent, and in combination with chemotherapy tumors essentially disappeared. Although the compounds proved effective against solid tumors, researchers believe they have potential to treat liquid tumors as well, such as the type found in leukemia and other blood cancers. "Our next step is to treat people with the drug in FDA-approved clinical trials," said Mayo.

7/9/2006 Pittsburgh, PA Lee Bowman ScrippsNews (www.scrippsnews.com) The Pittsburgh Pirates' dugout at PNC Park, site of Tuesday's All-Star game, is less likely to be tobacco-stained than was their lair in old Three Rivers Stadium when the Midsummer Classic was last played there 12 years ago. A newly published study_ based on 10 years of surveys and looking into the mouths of professional baseball players at Pirates spring training camps _ finds that smokeless-tobacco use among members of the club's major and minor league teams declined by more than a third between 1990 and 2000. Dipping and chewing goes way back with baseball. Many think the urge to chew and spit is a way to expend nervous energy between the next at-bat or the next play in the field, whether the chew is sunflower seeds, bubble gum or wads of tobacco. "A lot of players say they only use tobacco during the season or cut way down in the off-season. It's very much part of the cultural aspect of baseball," said Dr. Keith Sinusas, lead author of the study published in the July issue of Medicine and Science in Sports and Exercise. The difference, says Sinusas, is that tobacco users are much more likely to have one or more lesions or patches in or around the mouth that can progress to oral cancer. Since 1986, the U.S. Surgeon General has warned of a clear association between smokeless tobacco use and oral cancers. Sinusas and former Pirates team physician Dr. Joseph Coroso [...]
