RESUMO
PURPOSE: The University of Washington Quality of Life Questionnaire (UW-QOL) is an English-language survey used to assess the quality of life of patients with head and neck cancer. The present study aimed to translate this widely used questionnaire into Turkish according to international guidelines and to statistically determine its validity and reliability by administering it to native Turkish-speaking patients. MATERIALS AND METHODS: This prospective study was performed at Hacettepe University, Faculty of Medicine, Turkey. The study included patients newly diagnosed as having head and neck cancer. Translation and cultural adaptation of the questionnaire were performed first. Then, the translated version was tested on a consecutive series of patients seen in the department of otorhinolaryngology head and neck surgery and the department of radiation oncology between September 2006 and February 2008. The patients were asked to complete 3 sets of questionnaires. The first set was completed 1 day before the beginning of treatment, the second 3 months after the completion of treatment, and the third 10 days after the second questionnaire was completed. The first and second sets included the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire-Turkish version and UW-QOL-Turkish version. The third set included the Turkish UW-QOL only. Performance status was assessed and rated by a physician using the Karnofsky and ZEW (Zubrod/The Eastern Cooperative Oncology Group (ECOG)/World Health Organization) performance scales, synchronous with the first and second sets of questionnaires. RESULTS: The original English version of UW-QOL was carefully translated into Turkish, and a final Turkish version of UW-QOL was developed in an iterative fashion. To determine its validity and reliability, 67 patients were included in the study. Internal consistency (Cronbach α = .757) was adequate, and test-retest reliability (interclass correlation coefficient, 0.941) was excellent. The composite scores of the translated UW-QOL were compared statistically with the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire scores, Karnofsky and ZEW performance scales, T stage of the disease, and UW-QOL global questions scores to support the scale's construct validity, and statistically significant associations were observed. CONCLUSIONS: The Turkish UW-QOL appears to be a valid and reliable tool for use with Turkish patients with head and neck cancer; it can also be used in clinical investigations and routine clinical practice in Turkey.

PURPOSE: The purpose of the study was to determine the prognostic significance of the ratio between metastatic and examined lymph nodes to the survival rate of patients with squamous cell carcinoma of the head and neck. MATERIALS AND METHODS: The study included 142 patients in whom metastatic lymph nodes were observed in neck dissection specimens. The number of metastatic lymph nodes and the ratio of metastatic lymph nodes (RMLN) were compared as prognostic factors affecting overall survival (OS) and disease-free survival (DFS) rates. Survival curves were made using Kaplan-Meier analysis and were assessed by the log-rank test and Cox regression method. RESULTS: The median number of metastatic lymph nodes and RMLN for the entire study population were 2 and 4%, respectively. The OS and DFS rates were analyzed in the groups according to such stratification. The result of analysis of OS and DFS showed a statistically significant difference between patients with RMLN of at least 4% and those with RMLN less than 4% (hazard ratio, 3.4 and 2.7; P = .015 and P = .001, respectively). CONCLUSIONS: The ratio of metastatic lymph nodes has a significant impact on the survival period.

CONCLUSION: Preoperative chemoradiotherapy (CRT) was associated with a significantly higher rate of pharyngocutaneous fistula (PCF). OBJECTIVE: PCF is the most frequent complication following total laryngectomy. Although organ-preserving radiotherapy (RT) or CRT offer good locoregional control, many patients still require salvage laryngectomy. The aim of this study was to evaluate the factors that predispose patients to PCF, with a focus on preoperative RT, induction chemotherapy (ICT), and CRT. METHODS: This was a retrospective case series; 151 patients who underwent TL were reviewed. Preoperative RT, ICT, CRT, and some surgical parameters were analyzed as potential risk factors. RESULTS: The overall PCF rate was 13%. CRT was the only preoperative treatment that had a significant effect on PCF (35.3%, p = 0.004, odds ratio (OR) = 10.75). Surgery extended to the pharynx (p = 0.005, OR = 8.34) and vacuum drain duration (p = 0.012, OR = 5.16) were observed to be associated with PCF.

OBJECTIVE: Obstructive adenoid and tonsillar hyperplasia may present with retardation of growth. Interruption of growth hormone-insulin-like growth factor I axis resulting from abnormal nocturnal growth hormone secretion is among the postulated causes. Growth hormone (GH) mediates its anabolic effects on tissues through insulin-like growth factor I (IGF-I). Most of the circulating IGF-I is bound to insulin-like growth factor binding protein 3 (IGFBP3). The objective of this study is to determine blood serum levels of IGF-I and IGFBP3 in patients with adenoid and tonsillar hypertrophy. Furthermore, we want to investigate the effect of tonsillectomy and adenoidectomy (T&A) on these levels. STUDY DESIGN: The blood serum levels of IGF-I and its binding protein IGFBP3 were examined in 41 randomly selected children with a diagnosis of upper airway obstruction resulting from hypertrophic tonsils and adenoids. METHODS: Blood samples were taken preoperatively and repeated at 3 to 6 months (mean, 4.3 mo) following T&A operation. Coated-tube immunoradiometric assay (IRMA) method was used to analyze IGF-I and IGFBP3 levels. RESULTS: Thirty-two of 41 children were eligible for the analysis. When the preoperative and postoperative results were compared, it was found that there was a statistically significant increase in serum IGF-I and IGFBP3 levels in these 32 children (P <.001). In 7 of the 32 patients, the preoperative serum IGF-I levels were below normal. Postoperatively these levels increased within normal range. This was also statistically significant (P = .016). CONCLUSION: These findings revealed that obstructive adenoid and tonsillar hypertrophy may cause decreased serum IGF-I levels by affecting the GH-IGF-I axis, and T&A is an effective therapeutic measure in these patients.

Salivary duct carcinoma (SDC) is a highly malignant tumor that is histologically similar to ductal carcinoma of the breast. This article presents the clinicopathologic features of 15 patients with SDC arising in the salivary glands. The majority of patients were male and aged 65 years or older. The tumor was most often located in the parotid gland. Pain, facial palsy, and presence of calcification in the CT scan were diagnostic features suggestive of SDC. Histologically, 27% of the tumors arose from pre-existing pleomorphic adenoma. Perineural and lymphatic invasion were common findings. There was an extensive cervical lymph node involvement (73%). Distant metastasis was the most common cause of failure. Although SDC exhibits an unpredictable clinical course, total parotidectomy with neck dissection and adjunctive radiation therapy appear to be appropriate for local and regional control of this aggressive neoplasm.
