Quality of life before and after total laryngectomy: Results of a multicenter prospective cohort study
2013
Background The purpose of this study was to determine what quality of life (QOL) areas improve and deteriorate during the first year after total laryngectomy and to identify predictors of these changes. Methods One hundred seventy-four patients completed the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires before laryngectomy, n = 133 before discharge from hospital, n = 110 at the end of rehabilitation, and n = 86 1 year after laryngectomy. Multivariate regression analysis was performed to estimate the effect of potential predictors on QOL. Results Areas that did not recover to baseline level were physical functioning, role functioning, social functionin…
The influence of nimodipine on chromatolysis of motoneurons following axotomy with and without reinnervation: A quantitative image analysis
1996
Using a recently developed image analysis method to quantify the time course of chromatolysis in injured motorneurons we tested the effect of the calcium entry blocker nimodipine (1000 ppm in food pellets) on regenerating and degenerating motoneurons. Following facial-facial, hypoglossal-hypoglossal anastomosis with complete regeneration and following facial and hypoglossal nerve resection which causes a partial neuronal degeneration and postoperative survival times of 4 to 112 days, the texture of the Nissl substance of facial and hypoglossal motoneurons was analyzed on both sides of the brainstem in paraffin serial sections with a VIDASplus image analyzer. Monitoring alterations of the Ni…
The use of texture analysis to study the time course of chromatolysis
1998
Image analysis of the textural feature entropy of the Nissl substance was used to monitor the time course of chromatolysis in regenerating hypoglossal motoneurons and degenerating facial motoneurons 4-112 days after hypoglossal-facial anastomosis in rats. Changes in the Nissl substance were detected that were not obvious on the basis of subjective judgement of the light-microscopical appearance of the neurons. Chromatolysis started 4 days post operation (dpo) and was not reversed at 112 dpo in both nuclei. The increase of chromatolysis was 14-28 dpo faster in the regenerating hypoglossal neurons than in degenerating facial neurons. Maximal chromatolysis was measured at 56-70 dpo in both nuc…
Cetuximab, fluorouracil and cisplatin with or without docetaxel for patients with recurrent and/or metastatic squamous cell carcinoma of the head and…
2019
Abstract Background The combination of cisplatin, 5-fluorouracil (5-FU) and cetuximab (PFC) is the reference first-line treatment for recurrent/metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN). We analysed whether treatment intensification by the addition of docetaxel to PFC improved efficacy in R/M SCCHN. Methods A total of 180 patients with R/M SCCHN (1:1) were assigned to receive either cisplatin (40 mg/m2), docetaxel (40 mg/m2) and 5-FU (2000 mg/m2) at days 1 and 8 and cetuximab (400/250 mg/m2) at days 1, 8 and 15 (DPFC) or standard cisplatin (100 mg/m2) at day 1, 5-FU (1000 mg/m2) at days 1–4 and cetuximab (400/250 mg/m2) at days 1, 8 and 15 (PFC). Chemotherapy was…
Multicenter prospective study on the use and outcome of rehabilitation after total laryngectomy in Germany
2018
Background The purpose of this study was to assess the use and outcome of rehabilitation after total laryngectomy in Germany. Methods We enrolled patients who were scheduled for total laryngectomy, approached them again after surgery, after 3 months and 1 year. Patients completed questionnaires and were interviewed. Results Of 309 participants, 14% had not received any rehabilitation. Reasons for nonuse were primarily ongoing treatment and poor health. Users of rehabilitation had 4 times the odds of attaining any ability to speak compared to nonusers (odds ratio 3.8, P = .02). The main aim of rehabilitation from the perspective of the users was speech rehabilitation, mentioned by 71% before…
Quality of life during the first year after partial laryngectomy: Longitudinal study
2018
This prospective study was conducted to assess changes in quality of life (QOL) of patients who undergo a partial laryngectomy.The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires Core and Head and Neck (EORTC-QLQ-C30, QLQ-HN35) were used preprocedure (n = 218), 1 week (n = 159), 3 months (n = 122), and 1 year after partial laryngectomy (n = 88). Changes over time were analyzed with the Wilcoxon signed rank test and the Holm-Bonferroni method, and interpreted regarding clinical relevance.Most subscales worsened 1 week postprocedure, but many recovered to baseline level after 1 year. Dyspnea and cognitive functioning deteriorated over time, with worst…
Cetuximab, fluorouracil (5-FU), cisplatin, and docetaxel as first-line treatment in patients with recurrent and/or metastatic squamous cell carcinoma…

e17021 Background: This study investigates efficacy and toxicity of docetaxel added to cetuximab, cisplatin and 5-FU for patients with R/M SCCHN. We here report a planned second interim analysis to compare response rates between arms in order to decide on continuing to full accrual. Methods: Inclusion criteria were: stage III/IV R/M SCCHN and ECOG 0-1. Patients were randomized to arm A: cetuximab (standard dose) plus a maximum of 6 cycles of docetaxel (40 mg/m², day 1+8), cisplatin (40 mg/m², day 1+8) and 5-FU (2000 mg/m², day 1+8) or to arm B: cetuximab (standard dose), cisplatin (100 mg/m², day 1) and 5-FU (1000 mg/m², day 1-4). Treatment was administered until progression or intolerabil…
Quantitative image analysis of the chromatolysis in rat facial and hypoglossal motoneurons following axotomy with and without reinnervation.
1996
Image analysis was used to quantify the time course of chromatolysis in regenerating and degenerating motoneurons. Following facial-facial, hypoglossal-hypoglossal nerve suture, or resection of facial and hypoglossal nerves with postoperative survival times of 4 h to 112 days, the texture of the Nissl substance of facial and hypoglossal motoneurons was analyzed on both sides of the brainstem in paraffin serial sections with a VIDASplus image analyzer. In this quantitative study of 149 Wistar rats, alterations of the Nissl substance were measured that were statistically significant but not yet visible to the human eye. Chromatolysis started significantly as early as 8 h and was not fully rev…

2014
Background In this exploratory study, employment and psychological factors were investigated in head and neck cancer survivors with survivorship of ≥2 years. Methods Fifty-five head and neck cancer survivors ≤60 years old completed a survey including subscales from the Functional Assessment of Cancer Therapy (FACT) instrument, the Miller Behavioral Style Scale, the General Perceived Self-Efficacy Scale, the Patient Health Questionnaire-9 (PHQ-9), and the Hornheider–Fragebogen short version (HFB) measuring the need for psychological interventions. Exploratory analyses of associations to the employment status were performed. Results The rate of employed patients dropped from three-fourths of …
Tobacco and alcohol consumption after total laryngectomy and survival: A German multicenter prospective cohort study
2016
Background We examined the relation of tobacco and alcohol consumption after total laryngectomy with overall survival (OS). Methods Tobacco and alcohol consumption was assessed at 5 time points after total laryngectomy. Patients were followed up for survival until December 31, 2014. A multivariate Cox regression was fitted to test for differences in OS. Results Three hundred fifty-nine patients were included in this study. Compared to former smokers, never smokers had hazard ratios (HRs) of 0.88 (95% confidence intervals [CIs] = 0.50–1.59), and continuous smokers 1.31 (95% CI = 0.87–1.96). Constantly high alcohol consumption after total laryngectomy had an HR of 2.19 (95% CI = 1.30–3.67). D…
