    Title Intratumoral Delivery of Docetaxel Enhances Antitumor Activity of Ad-p53 in Murine Head and Neck Cancer Xenograft Model.
    Date May 2010
    Journal American Journal of Otolaryngology
    Excerpt

    The aim of this study is to determine the ability of intratumorally delivered docetaxel to enhance the antitumor activity of adenovirus-mediated delivery of p53 (Ad-p53) in murine head and neck cancer xenograft model.

    Title Effect of Docetaxel on the Surgical Tumor Microenvironment of Head and Neck Cancer in Murine Models.
    Date July 2008
    Journal Archives of Otolaryngology--head & Neck Surgery
    Excerpt

    OBJECTIVES: To identify the antitumor activity and wound-healing effect of docetaxel delivered in the surgical tumor microenvironment of head and neck squamous cell carcinoma (HNSCC). DESIGN: Control and experimental series. SETTING: Academic medical center. SUBJECTS: BALB/c and severe combined immunodeficiency mice. INTERVENTION: Intrawound (IW) docetaxel therapy was tested in 3 HNSCC xenograft and 2 taxane-resistant models. Intratumoral (IT) docetaxel therapy was further tested in the 2 taxane-resistant models. MAIN OUTCOME MEASURES: Tumor size, survival, and wound toxic effects were measured. The effect of docetaxel on various factors involved in wound healing and tumor growth within the surgical tumor microenvironment was also analyzed. RESULTS: In a pilot study using BALB/c mice, IW docetaxel therapy was not associated with problems in wound healing. Using the HN6, HN12, and HN30 HNSCC xenograft model, IW docetaxel prevented tumor growth and improved survival when compared with controls. No local or systemic toxic effect or wound-healing problem was noted. Using taxane-resistant xenograft lung cancer (H460/T800) and syngeneic salivary cancer (BALB/c mucoepidermoid carcinoma) models, IW therapy did not delay tumor growth. An antitumor effect was detected with repeated docetaxel injections in the H460/T800 taxane-resistant model but not in the BALB/c mucoepidermoid carcinoma model. Docetaxel inhibited the expression of growth factors and receptors in tumor cells; however, it did not inhibit the level of wound-healing growth factors in the surgical tumor microenvironment. CONCLUSIONS: These preclinical results support further testing of IW docetaxel treatment in HNSCC. Docetaxel appears to exert antitumor activity without affecting factors involved in wound healing in the tumor microenvironment.

    Title Laryngitis--diagnosis and Management.
    Date May 2008
    Journal Otolaryngologic Clinics of North America
    Excerpt

    Laryngeal inflammation includes a broad spectrum of pathologies, from infectious processes that need to be managed as airway emergencies, to indolent diseases that mimic head and neck cancer. The importance of a thorough history cannot be emphasized enough as it is the most important step toward developing a differential diagnosis. Vocal pathologies often have a noticeable impact on a person's quality of life and daily activities; therefore, it is key to counsel patients on the course of the disease process. Treatment of specific pathologies depends on the causative pathogen or etiology, as well as the age, vocal demands, and clinical characteristics of the individual.

    Title Pilot Study on Lower Nitrosamine Smokeless Tobacco Products Compared with Medicinal Nicotine.
    Date March 2008
    Journal Nicotine & Tobacco Research : Official Journal of the Society for Research on Nicotine and Tobacco
    Excerpt

    Smokeless tobacco (ST) products have the potential to be used as a harm reduction method for cigarette smokers. These products can deliver significantly less toxicants than cigarettes, although they are not toxicant free nor harmless. It is important to examine potential health risks and benefits of these products. These two small pilot studies examined the effects of two different ST products (Exalt and Ariva) compared with medicinal nicotine, another potential harm reduction product. Dependent, healthy adult cigarette smokers, who were motivated to quit smoking, underwent 1 week of baseline smoking measurement. They were then asked to quit smoking and were randomly assigned to use either an ST product or a medicinal nicotine lozenge (MNL, Commit) for 2 weeks, then crossed over to use the other product for 2 weeks. In the last week, following the sampling phase, subjects could choose the product they wished to use. Assessments were made repeatedly during baseline cigarette use and throughout the 5 weeks of treatment. Outcome measures included biomarkers for tobacco exposure and subjective, physiological, and behavioral responses. Tobacco-specific carcinogen uptake was greater from Exalt than from the MNL, and was comparable between the MNL and Ariva. Physiological effects and subjective effects on withdrawal and craving were comparable among Exalt, Ariva, and the MNL. Ariva was preferred over the MNL, which was preferred over Exalt. With the exception of medicinal nicotine products, low-nitrosamine ST products have the greatest potential to result in reduced toxicant exposure compared with other combustible reduced exposure products and have promise for reducing individual risk for disease. However, the population effect of marketing of such products as reduced exposure/reduced risk is unknown. The need for further research in this area and regulation of tobacco products is evident.

    Title Pilot Study of Intraoperative Chemotherapy with Cisplatin and 5-fluorouracil in Patients with Advanced Squamous Cell Carcinoma of the Head and Neck.
    Date April 2007
    Journal Head & Neck
    Excerpt

    BACKGROUND: Intraoperative manipulation of the tumor during cancer surgery has long been recognized as a source of metastasis and contamination of the surgical wound during tumor removal. We explored the use of intraoperative chemotherapy to minimize the risk of tumor cell implantation and metastasis during head and neck cancer surgery and conducted a dose escalating intraoperative chemotherapy clinical trial designed to assess the feasibility of this approach and associated toxicities in patients with advanced squamous cell carcinoma of the head and neck. METHODS: Fourteen patients were treated with 5-fluorouracil at a dose of 1000 mg/m(2) administered intravenously over an 8-hour period during the surgery with simultaneous cisplatin. The cisplatin dose was escalated and toxicity observed. Cisplatin at 75 mg/m(2) was chosen as the maximum tolerated dose level. RESULTS: One patient experienced a grade 3 nephrotoxicity, 1 patient a grade 1 neuropathy, and 5 patients grade 2 nausea (36%). There were no grade 4 toxicities. CONCLUSION: Intraoperative chemotherapy is feasible, and the combination of cisplatin at 75 mg/m(2) and 5-fluorouracil at 1000 mg/m(2) can be administered during surgery without significant toxicity.

    Title Histopathologic and Cytopathologic Diagnostic Discrepancies in Head and Neck Region: Pitfalls, Causes, and Preventive Strategies.
    Date March 2006
    Journal Otolaryngology--head and Neck Surgery : Official Journal of American Academy of Otolaryngology-head and Neck Surgery
    Excerpt

    BACKGROUND: Clinicians commonly utilize fine needle aspiration biopsy (FNAB) for the primary investigation of head and neck masses. Correlation of these results with the surgical resection diagnosis is an essential part of quality control and assurance programs in all cytology laboratories. METHODS: Of 610 cases, 20 (3.3%) had corresponding surgical resections performed within 3 months of the FNAB, with a discrepant diagnosis identified through a search that involved all FNABs performed on the head and neck region, excluding the thyroid gland, at Wayne State University between 1999 and 2004. Sites of discrepant samples included the parotid or submandibular gland (n = 5), lymph nodes (n = 8), and paratracheal/paraesophageal neck masses (n = 7). RESULTS: The reasons of false-negative FNABs included sampling errors (n = 3), insufficient material for an adequate interpretation (n = 5), lack of triage necessary for ancillary studies (n = 4), and interpretation errors (n = 6). There were 2 false-positive FNABs, both reported as mucoepidermoid carcinoma and showed chronic sialadenitis in one and lymphoepithelial cyst in the other. CONCLUSIONS: FNAB is an effective tool for the diagnosis and triage of patients with head and neck masses that can be further improved with an onsite immediate adequacy evaluation and triage performed by a pathologist.

    Title Urinary Metabolites of a Tobacco-specific Lung Carcinogen in Nonsmoking Hospitality Workers.
    Date December 2005
    Journal Cancer Epidemiology, Biomarkers & Prevention : a Publication of the American Association for Cancer Research, Cosponsored by the American Society of Preventive Oncology
    Excerpt

    Exposure of nonsmokers to environmental tobacco smoke results in increased risk for cancer and other diseases. In spite of this finding, some restaurants and bars continue to permit smoking. This study examined the uptake of nicotine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), a potent lung carcinogen, in nonsmokers who work in restaurants and bars that permitted smoking. Urine samples were collected for 24 hours on working and nonworking days and were analysed for total NNAL [the sum of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and its glucuronides (NNAL-Glucs)], metabolites of NNK. In addition, urine samples were analysed for total nicotine (nicotine plus nicotine glucuronide), and total cotinine (cotinine plus cotinine-N-glucuronide). The results showed significant increases in urinary levels of total NNAL, total nicotine, and total cotinine on working days compared with nonworking days. The results of this study show that smoke exposure in bars and restaurants may have important health effects on nonsmoking employees, elicited by the increase in carcinogen levels.
