Background We provided preliminary psychometric data for the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Head and Neck Module, updated version (QLQ-H&N43) from a group of Serbian laryngectomized patients. Methods The study included 170 subjects. The QLQ-H&N43 is a 43-item questionnaire, with 12 multi-item scales and 7 single-item symptom scales. All subjects also completed the Quality of Life Questionnaire-Core 30-questions (QLQ-C30). Results Good internal consistency (Cronbach's α of above 0.7) was found for 5 of the 7 scales. All QLQ-H&N43 scales correlated negatively as predicted with all QLQ-C30 functioning scales. The correlations with the QLQ-C30 symptoms supported discriminant validity, with only one exception: the head and neck social eating scale overlapped with the QLQ-C30 pain scale. For 14 of 19 QLQ-H&N43 scale scores, significant known-group differences were observed between those who differ in type of laryngectomy, adjuvant therapy, or 5-year survival. Conclusion Preliminary evidence suggests that a great majority of the QLQ-H&N43 scales have acceptable internal consistency and promising construct validity, but more research studies are needed with other cancer groups to extend these findings. © 2015 Wiley Periodicals, Inc..

Background/Aim. Laryngeal carcinomas make 1%-3% of all head and neck malignancies.Treatment outcome and survival rates depend greatly on established stage of the disease. The purpose of this study was to examine the survival of the patients with advanced laryngeal carcinoma depending on gender, age, common risk factors (tobacco and alcohol use), primary tumor localization, histopathological tumor grade, clinical TNM (tumor, node and metastasis) stage and surgical treatment of the disease. Methods. Retrospective study included 252 patients treated surgically for advanced squamocellular carcinoma of the larynx in a threeyear period with five-year follow-up. Patients included in the study were treated primary with surgery, with postoperative radiotherapy and chemotherapy depending on the stage of the disease, intraoperative findings and tumor resection borders. Overall survival and disease-specific five-year survival of patients was calculated for demographical and clinical characteristics of the patients. Results. Overall 5-year survival of patients with operable advanced laryngeal cancer included in the study was 86.14% and disease-specific survival 86.51%. Lower overall and the disease-specific survival was associated with age, higher histological tumor grade and more extensive neck dissections. Conclusion. Primary total laryngectomy results in higher survival outcomes in cases of transglottic T3 and T4a laryngeal tumors. Patients should be informed of the likely increased mortality risks tied to the choice of surgical resection and treatment modality before their decision. © 2020 Inst. Sci. inf., Univ.

There has recently been one hundred years since George Crile demonstrated systematic cervical lymph nodes excision for treatment of patients with head and neck cancer. Due to morbidity of the radical surgical approach, the emphasis was made on surgically conservative approach, in cases where it does not have adverse effects on disease control and still offers preservation of functional and cosmetic status. Modified radical neck dissection (MRND) removes "en block" the same lymph nodes and vessels as radical dissection, but by preserving one or more non-lymphatic structures that are being entirely removed by radical dissection, it decreases postoperative morbidity. Selective neck dissections, which are being preferred by American head and neck surgeons, went even further. The research was performed at Institute for Otolaryngology and Maxillofacial Surgery of Clinical Center of Serbia in Belgrade. The study included 319 patients treated period, from January 1, 1997 to December 31, 2001, who have been followed up for at least 5 years after treatment. Having in mind that this was retrospective clinical study, i.e. longitudinal study, the choice of patients and variables was made based on patient records. Of 302 patients with determined category, the most were in T2 category (40.44%), while T1 tumors were four times less frequent. It has been observed that metastases recurrences have occurred in 57/319 (17.86%) subjects at various time intervals. By analyzing recurrent metastases according to N categories, it has been determined that the most of them were in N1 and N2 category. This was expected, as N1 category was the most represented in the entire group of patients with 137/319 (42.94%) cases, and the largest number of neck dissections - 137/291 (47.08%), primarily SND, were performed within this category. Patient five-year survival in our study has been analyzed according to N category, type of neck dissection, and recurrence of metastases (Figure 2). Over the first two years of follow-up, there has been larger survival tendency in MRND group compared to SND. The difference became comparable in the third year, and increased in favor of SND by the end of follow-up period. Although arithmetic mean value was almost the same, and median value was higher in patients with MRND, there is no significant difference in five-year survival among patients with N1 category (0.43; df=1; p>0.05).
