    Salvage laryngectomy and pharyngocutaneous fistulae after primary radiotherapy for head and neck cancer: A national survey from DAHANCA

    Objective. In 1998, the Danish Society for Head and Neck Oncology decided to conduct a nationwide survey at the five head and neck oncology centers with the aim of evaluating the surgical outcome of salvage laryngectomy after radiotherapy with special emphasis on identifying factors that could contribute to the development of pharyngocutaneous fistulae. Patients. A total of 472 consecutive patients undergoing postirradiation salvage laryngectomy in the period July 1, 1987,June 30, 1997 were recorded at the five head and neck oncology centers in Denmark. Age ranged from 36 to 84 years, median 63 years, 405 men and 67 women. Primary tumor site was glottic larynx (n = 242), supraglottic larynx (n = 149), other larynx (n = 45), pharynx (n = 27), and other (n = 9). All patients had received prior radiotherapy. Results. Median time between radiotherapy and laryngectomy was 10 months (range, 1,348 months). A total of 89 fistulae lasting at least 2 weeks were observed, corresponding to an overall average fistulae risk of 19%. The number of performed laryngectomies per year decreased linearly (from 58 to 37), whereas the annual number of fistulae increased slightly (from 7 to 11), which meant that the corresponding estimated fistulae risk increased significantly from 12% in 1987 to 30% in 1997. Other significant risk factors for fistulae in univariate analysis included younger patient age, primary advanced T and N stage, nonglottic primary site, resection of hyoid bone, high total radiation dose, and large radiation fields. Multiple logistic regression analysis of these parameters suggested that nonglottic tumor site, late laryngectomy period (1987,1992 vs 1993,1997), and advanced initial T stage were independent prognostic factors for fistulae risk. Surgical parameters like resection of thyroid/tongue base/trachea or radiotherapy parameters like overall treatment time or fractions per week did not influence fistulae risk. Conclusions. The risk of fistulae is especially high in patients initially treated with radiotherapy for nonglottic advanced stage tumors. A significant decrease in the number of performed salvage laryngectomies over the 10 years was seen. Over the same time period, the annual number of fistulae remained almost constant. The resulting more than doubling of fistulae rate could thus in part be explained by less surgical routine. 2003 Wiley Periodicals, Inc. Head Neck 25: 711,716, 2003 [source]

    Surgical margin determination in head and neck oncology: Current clinical practice.

    Neck Society Member Survey, The results of an International American Head
    Abstract Background. Our aim was to investigate the ways in which surgeons who perform head and neck ablative procedures on a regular basis define margins, how they use frozen sections to evaluate margins, and the effect of chemoradiation on determining tumor margins. Methods. A custom-designed questionnaire was mailed to members of the American Head and Neck Society asking members how they evaluate and define tumor margins. Results. Of 1500 surveys mailed, 476 completed surveys were received. The most common response for distance of a clear pathologic margin was >5 mm on microscopic evaluation. A margin containing carcinoma in situ was considered a positive margin by most, but most did not consider a margin containing dysplasia a positive margin. When initial frozen section margins are positive for tumor and further resection results in negative frozen section margins, 90% consider the patient's margin negative. Most surgeons sample the frozen section from the surgical bed rather than from the main specimen. Nearly half use wider margins when resecting tumors treated with neoadjuvant therapy. When resecting recurrent or residual tumors treated with previous chemoradiation therapy, most resect to the pretreatment margin. Conclusions. No uniform criteria to define a clear surgical margin exist among practicing head and neck surgeons. Most head and neck surgeons consider margins clear if resection completed after an initial positive frozen section margin reveals negative margins, but this view is not shared by all. Most surgeons take frozen sections from the surgical bed; however, error may occur when identifying the positive margin within the surgical bed. The definition of a clear tumor margin after chemoradiation is unclear. These questions could be addressed in a multicenter prospective trial. 2005 Wiley Periodicals, Inc.

    Complementary and Alternative Medicine in Otolaryngology

    THE LARYNGOSCOPE, Issue 8 2001
    Benjamin F. Asher MD
    Abstract The widespread interest in and use of complementary and alternative medicine (CAM) by patients in the United States has been established by multiple surveys. One-third of the U.S. population uses some form of CAM, and an estimated 23 billion dollars is spent annually on these therapies. Because of prevalent usage of CAM among patients, it is important that physicians have some knowledge of this subject. With this purpose in mind, this report reviews the current research on CAM as it relates to common disorders of the head and neck: rhinitis, sinusitis, tinnitus, vertigo, and head and neck oncology.
