RESUMO
Hearing rehabilitation of patients with severe hearing loss or deafness using cochlear implants (CI) is a very successful but also complex and lifelong process that requires high quality standards for structure, process, and results. Medical registries represent an ideal tool for conducting quality control relevant to care while at the same time collecting scientific data. Therefore, at the initiative of the Executive Committee of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery (DGHNO-KHC), a Germany-wide CI registry (the German Cochlear Implant Register, DCIR) was to be established. The following goals were to be achieved: 1) legal and contractual basis for the register; 2) definition of the register contents; 3) development of evaluation standards (hospital-specific and national annual reports); 4) development of a logo; 5) practical operation of the registry. After defining a catalog of services that defines the content, structure, and operation of the DCIR, a registry operator with audiological expertise was sought. After considering various offers, the registry was technically implemented in cooperation with the provider INNOFORCE (Ruggell, Liechtenstein) as registry operator. This also included the realization of an interface for data transfer from previously existing databases and development of a data protection concept for productive operation of the DCIR under the scientific leadership of the DGHNO-KHC Executive Committee. Since January 2022, it has been possible for participating hospitals to enter pseudonymized data into the DCIR. To date, 75 hospitals in Germany have contractually agreed to participate in the registry. During the first 15 months, data from over 2500 implants in over 2000 patients were registered in the DCIR. The work presented here describes the structuring, development, and successful establishment of the DCIR. Introduction of the DCIR represents an important milestone of future scientifically based quality control in CI care. The registry presented here can therefore be considered as an example for other areas of medical care and thus also sets an international standard.

A standardized and structured process is indispensable for optimal hearing rehabilitation with cochlear implants (CI). The Executive Committee of the German Society of Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC), initiated the conception of a certification program and a Whitepaper based on the Association of the Scientific Medical Societies in Germany (AWMF) clinical practice guideline (CPG) describing the current medical standards of CI care in Germany. The goal was to independently confirm implementation of this CPG and make this information publicly available. With the support of an independent certification organization, successful implementation of the CI-CPG by a hospital would then be verified and confirmed by awarding the "Cochlear implant-provision institution" (Cochlea-Implantat-versorgende Einrichtung, CIVE) quality certificate. A structure for implementation of a certification system was developed based on the CI-CPG. The following steps were required: 1) conception of a quality control system for certification of hospitals working in accordance with the CI-CPG; 2) development of required structures for an independent review of quality-relevant structure, process, and result parameters; 3) development of a standard procedure for independent certification of hospitals; 4) development of a certificate and a logo to demonstrate successful certification; 5) practical implementation of the certification. Following design of the certification program and the required organizational structure, the certification system was successfully launched in 2021. Applications for the quality certificate could be formally submitted from September 2021. A total of 51 off-site evaluations were performed by December 2022. In the first 16 months from introduction, 47 hospitals were successfully certified as CIVE. In this period, 20 experts were trained as auditors, who have since then carried out 18 on-site audits in hospitals. In summary, the conceptual design, structure, and practical implementation of a certification program for quality control in CI care was successfully implemented in Germany.

PURPOSE: Lymphatic malformations (LM) are congenital malformations of the lymphatic system, mainly located in the head and neck area. They can be staged based on location according to de Serres and based on different morbidity items using the Cologne Disease Score (CDS), a clinical staging system. In many cases, functional impairment greatly affects the life of patients suffering from lymphatic malformations. The present study aims to analyze a cohort of pediatric patients with LM. METHODS: A retrospective analysis of 144 pediatric patients with head and neck LM was performed. Location, type of malformation (microcystic, macrocystic, mixed), scoring according to two different scoring systems and therapy were analyzed. Kruskal-Wallis test was used to analyze the difference in CDS between the patient groups and Dunn's test was used for post-hoc pairwise comparison. RESULTS: The average age at presentation was 6.1 years. The most common sites were neck (47%), cheek/parotid gland (26%), tongue (17%) and orbit (8%). Macrocystic malformations dominated the lateral neck, while microcystic malformations were predominantly localized in the tongue and floor of mouth. Macrocystic malformations (mean CDS 9.44) were associated with significantly better CDS than microcystic (mean CDS 7.11) and mixed (mean CDS 5.71) malformations (p < 0.001). LM in stage V according to de Serres had the lowest values (mean CDS: 4.26). The most common therapeutic procedures were conventional surgical (partial) resection, laser therapy and sclerotherapy with OK-432. CONCLUSIONS: There is an association between malformation type, location according to de Serres and CDS in children with LM of the head and neck. Patients with microcystic and mixed malformations in stage V had lowest CDS levels.

INTRODUCTION: Surgical reports are usually written after a procedure and must often be reproduced from memory. Thus, this is an error-prone, and time-consuming task which increases the workload of physicians. In this proof-of-concept study, we developed and evaluated a software tool using Artificial Intelligence (AI) for semi-automatic intraoperative generation of surgical reports for functional endoscopic sinus surgery (FESS). MATERIALS AND METHODS: A vocabulary of keywords for developing a neural language model was created. With an encoder-decoder-architecture, artificially coherent sentence structures, as they would be expected in general operation reports, were generated. A first set of 48 conventional operation reports were used for model training. After training, the reports were generated again and compared to those before training. Established metrics were used to measure optimization of the model objectively. A cohort of 16 physicians corrected and evaluated three randomly selected, generated reports in four categories: "quality of the generated operation reports," "time-saving," "clinical benefits" and "comparison with the conventional reports." The corrections of the generated reports were counted and categorized. RESULTS: Objective parameters showed improvement in performance after training the language model (p < 0.001). 27.78% estimated a timesaving of 1-15 and 61.11% of 16-30 min per day. 66.66% claimed to see a clinical benefit and 61.11% a relevant workload reduction. Similarity in content between generated and conventional reports was seen by 33.33%, similarity in form by 27.78%. 66.67% would use this tool in the future. An average of 23.25 ± 12.5 corrections was needed for a subjectively appropriate surgery report. CONCLUSION: The results indicate existing limitations of applying deep learning to text generation of operation reports and show a high acceptance by the physicians. By taking over this time-consuming task, the tool could reduce workload, optimize clinical workflows and improve the quality of patient care. Further training of the language model is needed.

PURPOSE: Children with extensive lymphatic malformations of the head and neck often suffer from functional impairment and aesthetic deformity which significantly affect the quality of life and may be life-threatening. Treatment with sirolimus has the potential to improve symptoms and downsize lymphatic malformations. This systematic review summarizes the current information about sirolimus treatment of lymphatic malformations of the head and neck in children, its efficacy and side effects. METHODS: A systematic search of the literature regarding studies on sirolimus treatment of children with lymphatic malformations of the head and neck was performed in PubMed, Embase, and Google Scholar up to July 2021 with the search terms "lymphatic malformation", "lymphangioma", "cystic hygroma", "low-flow malformation", "sirolimus", "rapamycin", "mTOR inhibitor" and "children". RESULTS: In all, 28 studies including 105 children from newborn to 17 years treated with sirolimus for lymphatic malformations of the head and neck were analyzed. The most frequent initial dose was 0.8 mg/m2 per dose, twice daily at 12-h interval. The target blood level differed between studies, 10-15 ng/mL and 5-15 ng/mL were most often used. More than 91% of the children responded to sirolimus treatment which lasts from 6 months to 4 years. Typical side effects were hyperlipidemia, neutropenia and infections. METHODS: Sirolimus could be an effective treatment for children with large complicated lymphatic malformations of the head and neck. As not all patients will benefit from treatment, the decision to treat sirolimus should be made by a multidisciplinary team.

BACKGROUND: The aim of the RESGEX study was to compare the efficacy and safety of the anti-epidermal growth factor receptor (anti-EGFR) antibody tomuzotuximab against cetuximab both in combination with chemotherapy in patients with recurrent and/or metastatic squamous cell cancer of the head and neck in the first-line treatment. PATIENTS AND METHODS: In this phase II trial 240 patients were equally randomized for six cycles to receive either tomuzotuximab (initial dose 990 mg then 720 mg) weekly and cisplatin 100 mg/m2 and fluorouracil (5-FU; 1000 mg/m2/day, days 1-4) every 3 weeks or cetuximab (400 mg/m2 subsequent 250 mg/m2) weekly with the same chemotherapeutic backbone followed by antibody maintenance treatment. The primary endpoint was progression-free survival. RESULTS: Median progression-free survival was 6.5 months [95% confidence interval (CI) 5.9-7.9 months] in the tomuzotuximab group and 6.2 months (95% CI 5.8-7.3 months) in the cetuximab group (P = 0.86). The median overall survival (OS) estimate was 11.6 months (95% CI 9.5-17.2 months) in the tomuzotuximab group and 13.8 months (95% CI 12.3-16.4 months) in the cetuximab group (P = 0.96). In an exploratory analysis a small subgroup of p16-positive patients had a significantly longer OS compared with p16-negative patients (hazard ratio 1.860, 95% CI 1.09-3.16, P = 0.02). CONCLUSIONS: The glyco-engineered antibody tomuzotuximab failed to demonstrate improved efficacy with a chemotherapeutic backbone in the first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma. It remains a so far unanswered question whether such antibody would partner better with different drugs such as checkpoint inhibitors.

BACKGROUND: In different cancer entities, several studies have shown the adverse effects of cancer on mental health, psychological well-being and the increased risk of high emotional distress in cancer patients. This study aims to analyze psychosocial distress levels and their relationship between sociodemographic parameters and selected items on the Distress Thermometer (DT) Problem List in head and neck squamous cell carcinoma (HNSCC) patients. PATIENTS AND METHODS: We assessed a total of 120 HNSCC patients using the Distress Thermometer (DT) Problem List. Distress scores (DTS) of 90 patients were available. A DTS of ≥ 5 on the visual analogue scale represents clinically relevant distress. Data analysis consisted of descriptive statistics, comparison of mean values for different DTS subcategories and correlation between DTS scores and parameters of tumor classification, sociodemographic variables and selected problems. RESULTS: Distress was present in 57.7% of the sample, with a total of 52 patients with a DTS ≥ 5. The mean DTS was 4.7 (SD 2.4). Patients with newly diagnosed HNSCC had significantly higher DTS. Distress levels were significantly associated with sadness, general worries, anxiety, nervousness, sleeping disorders, mouth sores and fever. Out of the total sample, 6 patients and out of these 6 individuals, 5 patients with a DTS ≥ 5 requested referrals to psycho-oncological service. CONCLUSION: High distress levels were common in HNSCC patients but only few patients desired psycho-oncological care. Addressing patients' supportive care needs in routine clinical practice is essential to meet unmet needs of HNSCC patients and thus improve cancer care.

BACKGROUND: Treatment of head and neck cancer (HNC) often leads to visible and severe functional impairments. In addition, patients often suffer from a variety of psychosocial problems, significantly associated with a decreased quality of life. We aimed to compare depression, anxiety, fatigue and quality of life (QoL) between HNC patients and a large sample of the general population in Germany and to examine the impact of sociodemographic, behavioral and clinical factors on these symptoms. METHODS: We assessed data of HNC patients during the aftercare consultation at the Leipzig University Medical Center with a patient reported outcome (PRO) tool named "OncoFunction". Depression, anxiety, fatigue and QoL were assessed using validated outcome measures including the PHQ-9, the GAD-2, and the EORTC QLQ-C30 questionnaire. RESULTS: A total of 817 HNC patients were included in our study and compared to a sample of 5018 individuals of the general German population. HNC patients showed significantly higher levels of impairment in all dimensions assessed. Examination of association between depression, anxiety, fatigue and QoL and clinical as well as sociodemographic variables showed significant relationships between occupational status, ECOG-state, body mass index and time since diagnosis. CONCLUSIONS: HNC patients suffer significantly from psychological distress. The used questionnaires are suitable for the use in daily routine practice and can be helpful to increase the detection of depression, anxiety and fatigue and therefore can improve HNC aftercare.

The treatment of patients with severe hearing loss or deafness with a cochlear implant (CI) represents a standard in Germany today. However, there is hardly any data on the current number of clinical CI centers (CI clinics) and their geographical distribution. The patient self-help organization, German Cochlear Implant Society (DCIG), and the German Society for Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) have therefore initiated a survey to determine the regional distribution, the range of services, the consideration of existing quality standards and cooperation with patient self-help organizations of the individual clinical CI centers.For this purpose, a total number of 170 ENT departments or their directors (37 professors and 133 chief physicians), respectively, were contacted by e-mail and provided with a questionnaire. The survey took place from October 2019 to February 2020.Of the 170 departments contacted, 71 (41.8â%) took part in the survey. Of these, 70 departments (98.6â%) confirmed to perform CI surgeries. Thus, 41.8â% of all clinics contacted reported to perform CI surgeries (70 of 170 clinics), while this information was not available from 99 clinics. All 70 clinical CI centers (100â%) reported to conduct CI surgeries on adults, 60 centers (85.7â%) also on children (<â18 years). 36 departments (51.4â%) reported that the total number of CI surgeries at their facility in 2018 was more than 50. In 64 departments (91.4â%), the recommendations of the DGHNO-KHC on CI care (according to the White Paper CI care 2018) were followed. A collaboration between the department and patient self-help organization was confirmed by 67 institutions (95.7â%). The geographical distribution of the clinical CI centers showed a heterogeneous distribution pattern between the individual federal states and also within the respective federal state.The work presented here is a first assessment of the situation with regard to the regional distribution of clinical CI centers in Germany. A clustering of CI centers was noticeable in metropolitan areas, sometimes with several facilities in one city. The predominant attention to quality-related aspects, such as the consideration of the DGHNO-KHC white paper and the cooperation with patient self-help, is gratifying. The limitations of the study result from limited participation in the survey (41.8â% of the contacted clinics).

Patients with locoregionally advanced laryngeal and hypopharyngeal squamous cell carcinomas (LHSCC) comprise two broad groups: those who are candidates for functional larynx preservation (LP) with avoidance of ablative surgery and those who are not. Currently, treatment depends on the patient's needs and wishes, the experience and recommendation of the surgeon, the philosophy of the institution, etc. The milestone VA trial established non-surgical LP in advanced LHSCC in the 1990s using induction chemotherapy (IC) with PF (cisplatin, P, plus 5fluorouracil, F) followed by irradiation (ICâ¯+ RT) as an appropriate alternative treatment to total laryngectomy (TL). Even though the findings of the VA trial were verified by the EORTC 24891 trial, a debate persists regarding the best protocol for balancing survival and laryngectomy-free survival (LFS) with acceptable late toxicity and good functional outcome. In advanced LHSCC without surgical options for larynx preservation, only ICâ¯+ RT or primary concurrent platin-based chemoradiotherapy (CRT) are accepted treatment options aiming to preserve a functional larynx. In the US, cisplatin-based CRT is exclusively recommended as the best curative protocol. With regards to long-term survival with functional organ preservation and persistently high failure rates, there is current discussion on the necessity of improving patient selection based on the current literature and the recently published data of the DeLOS-II trial.

BACKGROUND: In the field of immunotherapy of head and neck squamous cell carcinoma (HNSCC), a high level of study activity can still be observed. The results of the Keynote-048 study on first-line therapy with pembrolizumab were a highlight at this year's meeting of the American Society of Clinical Oncology (ASCO). MATERIALS AND METHODS: All abstracts and presentations on immunotherapy of head and neck tumors presented at ASCO 2019 were evaluated for relevance and the most interesting studies were summarized. RESULTS: The Keynote-048 study showed an improvement in overall survival with pembrolizumab monotherapy for patients with measurable programmed cell death ligand 1 (PD-L1) expression according to the combined positive score (CPS), and for the whole cohort with the combination of pembrolizumab and platin/5-fluorouracil (FU). The EAGLE study on durvalumab⯱ tremelimumab in second-line therapy did not demonstrate any improvement in response rates or overall survival compared to standard therapy. In addition, several new immunotherapeutic approaches and combinations were presented. CONCLUSION: The results of the Keynote-048 study have already led to the approval of pembrolizumab in the first line for platin-sensitive HNSCC in the USA and the expected approval in Europe will presumably change the therapeutic landscape in the long term. In the future, effective therapies for patients without a response to programmed cell death 1 (PD-1)/PD-L1 inhibition will be needed.

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 repeated every 21 days and continued for a maximum of 6 cycles in absence of disease progression or limiting toxicity, followed by cetuximab maintenance (500 mg/m2 every 2 weeks). The primary end-point was progression-free survival (PFS). RESULTS: A preplanned interim analysis for toxicity after 20 patients/arm revealed excessive grade 3 and 4 gastrointestinal (65%) and infectious toxicities (35%) in arm A, which led to dose reduction of cisplatin to 30 mg/m2 and 5-FU to 1000 mg/m2 for subsequent patients. With a median follow-up of 2 years, grade 4 toxicities were 21.3% vs. 30.8% for DPFC and PFC, respectively. More treatment-related deaths occurred with DPFC vs. PFC, with 11.2% and 6.6%, respectively. For DPFC and PFC, the median PFS was 6.3 vs. 6.4 months (hazard ratio [HR] = 0.97, p = 0.87), the median overall survival was 8.9 vs. 10.6 months (HR = 1.29 p = 0.1) and response rates were 38.2% vs. 31.9% (p = 0.9), respectively. CONCLUSIONS: DPFC failed to improve efficacy in R/M SCCHN. On the contrary, a high toxicity and mortality rate was detected in both arms, which underscores the vulnerability of patients with R/M SCCHN, and research on the need for further optimisation of the front-line chemotherapy backbone is ongoing.

Background: The German multicenter randomized phase II larynx organ preservation (LOP) trial DeLOS-II was carried out to prove the hypothesis that cetuximab (E) added to induction chemotherapy (IC) and radiotherapy improves laryngectomy-free survival (LFS; survival with preserved larynx) in locally advanced laryngeal/hypopharyngeal cancer (LHSCC). Patients and methods: Treatment-naïve patients with stage III/IV LHSCC amenable to total laryngectomy (TL) were randomized to three cycles IC with TPF [docetaxel (T) and cisplatin (P) 75 mg/m2/day 1, 5-FU (F) 750 mg/m2/day days 1-5] followed by radiotherapy (69.6 Gy) without (A) or with (B) standard dose cetuximab for 16 weeks throughout IC and radiotherapy (TPFE). Response to first IC-cycle (IC-1) with ≥30% endoscopically estimated tumor surface shrinkage (ETSS) was used to define early responders; early salvage TL was recommended to non-responders. The primary objective was 24 months LFS above 35% in arm B. Results: Of 180 patients randomized (July 2007 to September 2012), 173 fulfilled eligibility criteria (A/B: larynx 44/42, hypopharynx 41/46). Because of 4 therapy-related deaths among the first 64 randomized patients, 5-FU was omitted from IC in the subsequent 112 patients reducing further fatal toxicities. Thus, IC was TPF in 61 patients and TP in 112 patients, respectively. The primary objective (24 months LFS above 35%) was equally met by arms A (40/85, 47.1%) as well as B (41/88, 46.6%). One hundred and twenty-three early responders completed IC+RT; their overall response rates (TPF/TP) were 94.7%/87.2% in A versus 80%/86.0% in B. The 24 months overall survival (OS) rates were 68.2% and 69.3%. Conclusions: Despite being accompanied by an elevated frequency in adverse events, the IC with TPF/TP plus cetuximab was feasible but showed no superiority to IC with TPF/TP regarding LFS and OS at 24 months. Both early response and 24 months LFS compare very well to previous LOP trials and recommend effective treatment selection and stratification by ETSS. Clinical trial information: NCT00508664.

BACKGROUND: Immunotherapeutic strategies are becoming increasingly more important for head and neck cancer and numerous clinical trials were presented at the annual meeting of the American Society of Clinical Oncology (ASCO) 2018. OBJECTIVE: In this review the most interesting clinical trials and trial results for immunotherapy of head and neck cancer are summarized. MATERIAL AND METHODS: All abstracts and presentations on immunotherapy of head and neck cancer at the annual meeting of the ASCO 2018 were screened to select the most interesting trials for a more detailed analysis.
