08:10 Racial Patterns of Thyroid Cancer Incidence in the U.S. Luc GT Morris, MD (presenter); Andrew Sikora, MD, PhD; Daniel Jethanamest, MD; Mark D DeLacure, MD
OBJECTIVES: In contradistinction to other cancers, black Americans have a lower incidence of thyroid cancer than whites. It is unknown if this is due to racial disparity in detection, or a true difference in incidence. This study hypothesized that the incidence gap might be attributable to poorer 08:02 cancer detection in blacks. Recurrent Laryngeal and Pharyngeal Cancer METHODS: Population-based cohort study of 53,990 patients Salvaged with TLM David George, Grant MB, ChB, BSc (St And) (presenter); between 1973-2003, using the Surveillance Epidemiology End Results (SEER) database.

Macrocyst (⬎1cm) access performed with coaxial 5F catheter system and treated with dual-drug chemoablation (sequential intracystic sodium tetradecyl sulfate and ethanol); doxycycline used for microcyts. Macrocysts and microcysts were treated after complete cyst aspiration with sonographic guidance. Macrocyst containment was confirmed with fluoroscopic cystography. Catheter drainage for macrocystic treatment was maintained for three days following treatment. Fifty-four macrocysts and 40 microcysts were treated; goals of treatment are complete cyst ablation documented by sonography, CT, or MR imaging, and excellent cosmetic results. RESULTS: Mean number of treatments ⫽ 1.7 per patient; mean number of treatments for macrocysts ⫽ 1.1; mean treatments for microcysts ⫽ 2.1 (macrocysts and microcysts most often treated as separate sessions). Treatment efficacy 54/54: macrocysts ablated (100%); microcyst controlled 17/17 pts; follow-up 2-60 mo. Treatments included massive cervical cysts and cysts surrounding the facial nerve and brachial plexus. Complications: infection in 2/31 patients; no postprocedural pain or other complications. CONCLUSIONS: Percutaneous interventional radiological regimens provide effective treatment, with rapid resolution, for macrocystic and microcystic LM as primary treatment, or for recurrence following surgical resection, without serious complications or deformity.
08:28 Effect of Neck Dissection on Quality of Life after Chemo-XRT Amy-Anne Donatelli Lassig, MD (presenter); Sonia A Duffy, PhD; Karen Fowler, MPH; Jeffrey E Terrell, MD OBJECTIVES: 1. Understand the differences in quality of life (QOL) in oropharyngeal squamous cell carcinoma patients treated with chemoradiation alone versus chemoradiation and neck dissection. 2. Evaluate such changes over time. METHODS: A prospective cohort study (2001 to present) was conducted at otolaryngology clinics at 2 tertiary care centers and a Veterans Affairs hospital. Patients: sample of 111 patients with SCCA of the oropharynx treated via chemotherapy and radiation therapy with or without neck dissection. Intervention: patients completed a self-administered health survey to collect health, demographic, and QOL information pretreatment and one year later. Clinical/treatment data and tumor site/stage were ascertained from the medical record. The main outcome measures were QOL as assessed by the SF-36 and HNQoL instruments. Type of treatment given was the independent variable. Descriptive statistics were calculated for all health and clinical characteristics, demographics, and QOL scores. T test was used to evaluate changes in QOL over time. RESULTS: Of 111 patients treated for oropharyngeal SCCA, 73 patients were treated with chemoradiation alone and 38 with
chemoradiation and neck dissection. There were no significant differences in QOL between the two groups. Only the pain index of the SF-36 approached significance (p equals .055) with the neck dissection group reporting greater pain. CONCLUSIONS: There are no significant differences in QOL in patients with SCCA of the oropharynx treated via chemoradiation alone versus chemoradiation and neck dissection. As the debate continues regarding the role of post-treatment neck dissection, this lack of added decrement in QOL should be considered.
08:36 Compare ALT and FRFF Flaps for Hypopharyngeal Reconstruction Johnson Chia-shen Yang, MD (presenter); Seng-feng Jeng, MD OBJECTIVES: Study and compare the functional outcomes associated with free anterior lateral thigh (ALT) and free radial forearm flaps (FRFF) for the reconstruction of hypopharyngeal defects. METHODS: A retrospective study for seven years (August 1999 to May 2006); 66 patients received 42 FRFF and 24 ALT flaps for reconstruction after hypopharyngeal cancer ablation. All reconstructions were performed by the same senior plastic surgeon. All patients were male, averaged 54 years old. Fiftyone skin tubing and 15 patches were designed for the defects. The average pharyngoesophageal defects was 84 cm2. The mean follow-up time was 44.5 months for the forearm group, and 10.7 month for the ALT group. Functional outcomes were compared. Chi-squared test used for statistical analysis. RESULTS: Twenty-three out of 42 patients in the forearm group and 12 out of 24 patients in the ALT group have completed an esophagogram for evaluation. Smooth barium passage was found in 83.3% of the ALT group as compared to 34.8% in the forearm group. The P-value is 0.006, which is statistically significant, based on Chi-square test. CONCLUSIONS: The ALT flap has several advantages such as minimal donor site morbidity, and it is a bulkier flap which helps to eliminate dead spaces as compared with FRFF. The lower fistula formation rate also leads to better functional outcome as demonstrated by an esophagogram. The ALT flap is therefore the preferred flap for hypopharyngeal reconstruction.
08:44 Identifying Candidates for Unilateral Parathyroidectomy James Norman, MD (presenter); Douglas Politz OBJECTIVES: Identify preoperative clinical data that may predict excellent versus poor candidates for unilateral parathyroidectomy.
