A survey was conducted to identify demographics and standards of care for treatment of hypopharyngeal squamous cell carcinoma in the United States. Data were accrued from voluntary submission of cancer registry and medical chart information from 769 hospitals representing 2939 cases diagnosed from 1980 to 1985 and 1990 to 1992. Clinical findings, diagnostic procedures employed, treatment practices, and outcome are presented. Overall, 5-year disease-specific survival was 33.4%, which segregated to 63.1% (stage I), 57.5% (stage II), 41.8% (stage III), and 22% (stage IV). Survival was best for patients treated with surgery only (50.4%), similar with combined surgery and irradiation (48%), and worse with irradiation only (25.8%). This analysis provides a standard to which current treatment practice and future clinical trials may be compared.

The most commonly used incision for parotidectomies is the modified Blair incision. We have successfully used an alternative incision which allows good exposure, and leaves no neck scar.Between 1 March 1989 and 1 August 1991, 18 parotidectomies were performed using a modified facelift incision. Fifteen parotidectomies were done for similar indications during the same period using a modified Blair incision. The mean age in both groups of patients was 40.3 years. The pathology and incidence of complications was similar in the two groups. The difference in mean (±SD) time of surgery between the two groups was not statistically significant: 3.14 ±0.75 hours in patients with a modified facelift incision and 3.25 ±1.27 hours in patients with a modified Blair incision (p<20.1).The modified facelift incision is an alternative approach to parotidectomy for selected patients. It provides adequate exposure, even for a total parotidectomy and mastoidectomy and it results in improved patient satisfaction without additional risk of complications.

BACKGROUND:In head and neck cancer (HNC), 3-month post-treatment positron emission tomography (PET)/computed tomography (CT) reliably identifies persistent/recurrent disease. However, further PET/CT surveillance has unclear benefit. The impact of posttreatment PET/CT surveillance on outcomes is assessed at 12 and 24 months. METHODS: A 10-year retrospective analysis of HNC patients was carried out with long-term serial imaging. Imaging at 3 months included either PET/CT or magnetic resonance imaging, with all subsequent imaging comprised of PET/CT. PET/CT scans at 12 and 24 months were evaluated only if preceding interval scans were negative. Of 1114 identified patients, 284 had 3-month scans, 175 had 3-and 12-month scans, and 77 had 3-, 12-, and 24-month scans. RESULTS: PET/CT detection rates in clinically occult patients were 9% (15 of 175) at 12 months, and 4% (3 of 77) at 24 months. No difference in outcomes was identified between PET/CT-detected and clinically detected recurrences, with similar 3-year diseasefree survival (41% vs 46%, P ¼ .91) and 3-year overall survival (60% vs 54%, P ¼ .70) rates. Compared with 3-month PET/CT, 12-month PET/CT demonstrated fewer equivocal reads (26% vs 10%, P < .001). Of scans deemed equivocal, 6% (5 of 89) were ultimately found to be positive. CONCLUSIONS: HNC patients with negative 3-month imaging appear to derive limited benefit from subsequent PET/ CT surveillance. No survival differences were observed between PET/CT-detected and clinically detected recurrences, although larger prospective studies are needed for further investigation.

The review of our experience with PEG tube placement revealed a low complication rate. Safe PEG placement was achieved by transillumination of the abdominal wall and confirmation by ballottement. In addition, appropriate patient selection, use of perioperative antibiotics, as well as meticulous post-procedure care contributed to the low rate of complications. For the patients with head and neck cancer, a barrier should be placed between the tumor and the instrumentation at the time of tube placement.

PET is effective in detecting distant metastases in the posttreatment surveillance for HNSCC patients. A negative PET is highly reliable for all sites. However, a positive PET in the head and neck region is unreliable because of a high false-positivity rate. PET of the head and neck region has a statistically significant risk of a false-negative reading when performed within 1 month of radiation.

One hundred thirty-eight patient courses of tobramycin (tobra) and gentamicin (genta) were prospectively monitored for ototoxicity using weekly audiograms and electronystagmograms. Twice weekly drug serum levels and kidney function tests were determined. A pre, during, and post-therapy history was obtained and the results were analyzed to determine significant parameters of ototoxicity. Statistical analysis of the data was performed using SPSS on an IBM 370/3033 computer. Tobra showed less toxicity than genta but only the difference in vestibular toxicity was statistically significant. Significant associations with toxicity included the patient developing a high temperature, total dose, low hematocrit for tobra, high hematocrit for genta, high creatinine clearance with cochlear toxicity, high creatinine with nephrotoxicity, poor condition or critically ill, and duration of therapy greater than 10 days. Non-significant parameters included dose rate (mg/kg), serum levels, age, prior noise exposure, prior aminoglycosides, prior ear infections, non-aminoglycoside ototoxic drugs, underlying disease, or total number of high risks present. Ototoxicity was independent of nephrotoxicity.
