RESUMEN
PURPOSE: In 1968, Steinmann described the hyoid bone syndrome as a degenerative and inflammatory insertion tendinosis. It causes unilateral pain in the neck, increased by swallowing and palpation. The treatment is conservative, but when this fails, surgery is an option. Our aim is to assess the post-operative outcome of patients for whom a surgical hyoid bone resection procedure was performed in the University Hospital of Antwerp (UZA). METHODS: A retrospective study was performed. Patients were seen at the laryngology clinic in the UZA from 2018 until 2023. They were diagnosed with the hyoid bone syndrome based on anamnesis and clinical examination. Pre-operative imaging was performed to evaluate for anatomical changes and fiberoptic laryngoscopy performed to exclude other causes. Pre- and postoperative VAS pain scores were questioned. RESULTS: Seventeen patients were operated, two of them bilaterally. All patients had pain located to the affected side, and almost half of patients (n = 7) had dysphagia. On imaging, 10 patients had an elongated styloid process and 7 had calcification of the stylohyoid ligament. All patients underwent resection of the greater horn of the hyoid bone, 13 patients underwent resection of the stylohyoid ligament and in 9 patients the superior horn of the thyroid cartilage was removed. Mean pre-operative VAS pain score was 9 (/10) and mean postoperative score was 1.3 (/10). CONCLUSION: Our preliminary results show a good clinical effect of the surgical excision procedure and offer insight in the hyoid bone syndrome. Follow-up is necessary to assess the long-term results and potential recurrence of symptoms.
RESUMEN
BACKGROUND: Prophylactic swallowing exercises (PSE) during radiotherapy can significantly reduce dysphagia after radiotherapy in head and neck cancer (HNC). However, its positive effects are hampered by low adherence rates during the burdensome therapy period. Hence, the main goal of this multicenter randomized controlled trial (RCT) was to investigate the effect of 3 different service-delivery modes on actual patients' adherence. METHODS: A total of 148 oropharyngeal cancer patients treated with primary (chemo)radiotherapy were randomly assigned to a 4 weeks PSE program, either diary-supported (paper group; n = 49), app-supported (app group; n = 49) or therapist-supported (therapist group; n = 50). Participants practiced 5 days/week, daily alternating tongue strengthening exercises with chin tuck against resistance exercises. Adherence was measured as the percentage of completed exercise repetitions per week (%reps). Statistical analysis was performed by means of SPSSv27, using Linear Mixed-effects Models with post hoc pairwise testing and Bonferroni-Holm correction. RESULTS: Adherence and evolution of adherence over time was significantly different between the three groups (p < .001). Adherence rates decreased in all three groups during the 4 training weeks (p < .001). During all 4 weeks, the therapist group achieved the highest adherence rates, whilst the app group showed the lowest adherence rates. CONCLUSIONS: PSE adherence decreased during the first 4 radiotherapy weeks regardless of group, but with a significant difference between groups. The therapist group achieved the highest adherence rates with a rather limited decline, therefore, increasing the face-to-face contact with a speech-language therapist can overcome the well-known problem of low adherence to PSE in this population.

BACKGROUND: The Hopkins criteria were introduced for nodal response evaluation after therapy in head and neck cancer, but its superiority over quantification is not yet confirmed. METHODS: SUVbody weight thresholds and lesion-to-background ratios were explored in a prospective multicenter study of standardized FDG-PET/CT 12 weeks after CRT in newly diagnosed locally advanced head and neck squamous cell carcinoma (LAHNSCC) patients (ECLYPS). Reference standard was histology, negative FDG-PET/CT at 12 months after treatment or ≥ 2 years of negative follow-up. Area under the receiver operator characteristics curves (AUROC) were estimated and obtained thresholds were validated in an independent cohort of HNSCC patients (n = 127). RESULTS: In ECLYPS, 124 patients were available for quantification. With a median follow-up of 20.4 months, 23 (18.5%) nodal neck recurrences were observed. A SUV70 threshold of 2.2 (AUROC = 0.89; sensitivity = 79.7%; specificity = 80.8%) was identified as optimal metric to identify nodal recurrence within 1 year after therapy. For lesion-to-background ratios, an SUV50/SUVliver threshold of 0.96 (AUROC = 0.89; sensitivity = 79.7%; specificity = 82.8%) had the best performance. Compared with Hopkins criteria (AUROC = 0.81), SUV70 and SUV50/SUVliver provided a borderline significant (p = 0.040 and p = 0.094, respectively) improvement. Validation of thresholds yielded similar AUROC values (SUV70 = 0.93, SUV50/SUVliver = 0.95), and were comparable to the Hopkins score (AUROC = 0.91; not statistically significant). CONCLUSION: FDG quantification detects nodal relapse in LAHNSCC patients. When using EARL standardized PET acquisitions and reconstruction, absolute SUV metrics (SUV70 threshold 2.2) prove robust, yet ratios (SUV50/SUVliver, threshold 0.96) may be more useful in routine clinical care. In this setting, the diagnostic value of quantification is comparable to the Hopkins criteria. TRIAL REGISTRATION: US National Library for Medicine, NCT01179360.

PURPOSE: The aim of this study was to investigate the feasibility of tongue strength measures (TSMs) and the influence of bulb location, sex, and self-perceived pain and mucositis in head and neck cancer (HNC) patients during chemoradiotherapy (CRT). METHODS: Twenty-six newly diagnosed HNC patients treated with CRT performed anterior and posterior maximal isometric tongue pressures by means of the Iowa Oral Performance Instrument (IOPI). The Oral Mucositis Weekly Questionnaire (OMWQ) and a Visual Analogue Scale (VAS) for pain during swallowing were completed weekly from baseline to 1 week post CRT. RESULTS: Feasibility of TSMs during CRT declines significantly from 96 to 100% at baseline to 46% after 6 weeks of CRT. But post-hoc analyses reveal only significant differences in feasibility between baseline and measurements after 4 weeks of treatment. No effect of gender or bulb location was established, but feasibility is influenced by pain and mucositis. CONCLUSIONS: Feasibility of TSMs declines during CRT and is influenced by mucositis and pain. For the majority of subjects, TSMs were feasible within the first 4 weeks, which provides a window of scientific and clinical opportunities in this patient population.

BACKGROUND: Platinum-based concurrent chemoradiation (CCRT) improves locoregional control and overall survival of locoregionally advanced (LA) squamous cell carcinoma of the head and neck (SCCHN) when compared to radiotherapy alone, but this approach is hampered by significant toxicity. Therefore, alternative ways to enhance the radiation effects are worth investigating. Gemcitabine (2',2'-difluorodeoxycytidine), in addition to its activity against a variety of solid tumors, including SCCHN, is one of the most potent radiosensitizers, and it has an overall favorable safety profile. In this paper, the clinical experience with gemcitabine-based chemoradiation in the treatment of patients with LA-SCCHN is reviewed. METHODS: We conducted a review of the literature on the clinical experience with radiotherapy combined with either single-agent gemcitabine or gemcitabine/cisplatin-based polychemotherapy for the treatment of patients with LA-SCCHN. We also searched abstracts in databases of major international oncology meetings from the last 20 years. A meta-analysis was performed to calculate pooled proportions with 95% confidence intervals (CIs) for complete response rate and grade 3-4 acute mucositis rate. RESULTS: A total of 13 papers were eligible for the literature review. For schedules using a gemcitabine dose intensity (DI) below 50 mg/m(2) per week, the complete response rate was 86% (95% CI, 74%-93%) with grade 3-4 acute mucositis rate of 38% (95% CI, 27%-50%) and acceptable late toxicity. In one of the studies employing such low DIs, survival data were provided showing a 3-year overall survival of 50%. Compared with DI ≥50 mg/m(2) per week, there was no difference in the complete response rate (71%; 95% CI, 55%-83%; p = .087) but a significantly higher (p < .001) grade 3-4 acute mucositis rate of 74% (95% CI, 62%-83%), often leading to treatment interruptions (survival data provided in 8 studies; 3-year overall survival, 27%-63%). Late toxicity comprising mainly dysphagia was generally underreported, whereas information about xerostomia and skin fibrosis was scarce. CONCLUSION: This review highlights the radiosensitizing potential of gemcitabine and suggests that even very low dosages (less than 50 mg/m(2) per week) provide a sufficient therapeutic ratio and therefore should be further investigated. Refinements in radiation schemes, including intensity-modulated radiation therapy, in combination with low-dose gemcitabine and targeted agents, such as cetuximab, are currently being investigated. IMPLICATIONS FOR PRACTICE: Cisplatin-based concurrent chemoradiation (CCRT) has become the standard treatment of locally advanced head and neck cancer (LAHNC). This approach is hampered by significant toxicity. This paper reviews the studies using gemcitabine as an alternative radio-sensitizer for CCRT in patients with LAHNC. In this capacity, despite its mild intrinsic toxicity, gemcitabine comes with high rates of severe mucositis when used in dosages exceeding 50 mg/m(2) per week. CCRT with low-dose gemcitabine provides a sufficient therapeutic ratio, combining clinical activity, similar to the higher-dose regimens, with lower toxicity. Further investigation is warranted.

BACKGROUND: In recurrent head and neck squamous cell carcinoma ineligible for resection or irradiation, treatment aims primarily at symptom control and quality of life enhancement with an expected outcome of 6-12 months. METHODS: In 2005, a male patient, born in 1944, with a second local recurrence of human papillomavirus negative tonsil cancer was enrolled in the EXTREME trial, and randomized to platinum/5-fluorouracil/cetuximab arm resulting in partial remission with progression-free survival of 12 months. The second-line systemic therapy comprised 5 cycles of 3-weekly docetaxel/cisplatin/5-fluorouracil regimen plus weekly cetuximab. RESULTS: As confirmed on imaging and repeated biopsies, complete response was achieved with disease-free survival of 8 years and follow-up period of 12 years. Severe acute toxicities during the taxane-based chemotherapy plus cetuximab included grade 4 anorexia and grade 3 febrile neutropenia. CONCLUSIONS: Poor tumor differentiation, no weight loss, oropharyngeal location, white race, and particularly the induced complete response were most likely the key favorable prognostic factors in the reported patient. The possibility of a synergistic interaction between taxanes and cetuximab should be further explored.

BACKGROUND: We report on a retrospective analysis of 147 patients with early and locoregionally advanced squamous cell head and neck cancer (SCCHN) treated with helical tomotherapy (HT). PATIENTS AND METHODS: Included were patients with SCCHN of the oral cavity (OC), oropharynx (OP), hypopharynx (HP), or larynx (L) consecutively treated in one radiotherapy center in 2008 and 2009. The prescribed HT dose was 60-66 Gy in the postoperative setting (group A) and 66-70 Gy when given as primary treatment (group B). HT was given alone, concurrent with systemic therapy (ST), that is, chemotherapy, biotherapy, or both, and with or without induction therapy (IT). Acute and late toxicities are reported using standard criteria; locoregional failure/progression (LRF), distant metastases (DM), and second primary tumors (SPT) were documented, and event-free survival (EFS) and overall survival (OS) were calculated from the start of HT. RESULTS: Group A patients received HT alone in 22 cases and HT + ST in 20 cases; group B patients received HT alone in 17 cases and HT + ST in 88 cases. Severe (grade ≥ 3) acute mucosal toxicity and swallowing problems increased with more additional ST. After a median follow-up of 44 months, grade ≥2 late toxicity after HT + ST was approximately twice that of HT alone for skin, subcutis, pharynx, and larynx. Forty percent had grade ≥2 late xerostomia, and 29% had mucosal toxicity. At 3 years, LRF/DM/SPT occurred in 7%/7%/17% and 25%/13%/5% in groups A and B, respectively, leading to a 3-year EFS/OS of 64%/74% and 56%/63% in groups A and B, respectively. CONCLUSION: The use of HT alone or in combination with ST is feasible and promising and has a low late fatality rate. However, late toxicity is nearly twice as high when ST is added to HT.

A decade after its first introduction into the clinic, little is known about the clinical impact of helical tomotherapy (HT) on head and neck cancer (HNC) treatment. Therefore, we analyzed the basics of this technique and reviewed the literature regarding HT's potential benefit in HNC. The past two decades have been characterized by a huge technological evolution in photon beam radiotherapy (RT). In HNC, static beam intensity-modulated radiotherapy (IMRT) has shown superiority over three-dimensional conformal RT in terms of xerostomia and is considered the standard of care. However, the next-generation IMRT, the rotational IMRT, has been introduced into the clinic without any evidence of superiority over static beam IMRT other than being substantially faster. Of these rotational techniques, HT is the first system especially developed for IMRT in combination with image-guided RT. HT is particularly promising for the treatment of HNC because its sharp dose gradients maximally spare the many radiosensitive organs at risk nearby. In addition, HT's integrated computed tomography scan assures a very precise dose administration and allows for some adaptive RT. Because HT is specifically developed for IMRT in combination with (integrated) image-guidance, it allows for precise dose distribution ("dose painting"), patient setup, and dose delivery. As such, it is an excellent tool for difficult HNC irradiation. The literature on the clinical results of HT in HNC all show excellent short-term (≤2 years) results with acceptable toxicity profiles. However, properly designed trials are still warranted to further substantiate these results.

BACKGROUND: FDG-PET/CT has a high negative predictive value to detect residual nodal disease in patients with locally advanced squamous cell head and neck cancer after completing concurrent chemoradiotherapy (CCRT). However, the positive predictive value remains suboptimal due to inflammation after radiotherapy, generating unnecessary further investigations and possibly even surgery. We report the results of a preplanned secondary end point of the ECLYPS study regarding the potential advantages of dual time point FDG-PET/CT imaging (DTPI) in this setting. Standardized dedicated head and neck FDG-PET/CT images were obtained 12 weeks after CCRT at 60 and 120 min after tracer administration. We performed a semiquantitative assessment of lymph nodes, and the retention index (RI) was explored to optimize diagnostic performance. The reference standard was histology, negative FDG-PET/CT at 1 year, or > 2 years of clinical follow-up. The time-dependent area under the receiver operator characteristics (AUROC) curves was calculated. RESULTS: In total, 102 subjects were eligible for analysis. SUV values increased in malignant nodes (median SUV1 = 2.6 vs. SUV2 = 2.7; P = 0.04) but not in benign nodes (median SUV1 = 1.8 vs. SUV2 = 1.7; P = 0.28). In benign nodes, RI was negative although highly variable (median RI = - 2.6; IQR 21.2), while in malignant nodes RI was positive (median RI = 12.3; IQR 37.2) and significantly higher (P = 0.018) compared to benign nodes. A combined threshold (SUV1 ≥ 2.2 + RI ≥ 3%) significantly reduced the amount of false-positive cases by 53% (P = 0.02) resulting in an increased specificity (90.8% vs. 80.5%) and PPV (52.9% vs. 37.0%), while sensitivity (60.0% vs. 66.7%) and NPV remained comparably high (92.9% vs. 93.3%). However, AUROC, as overall measure of benefit in diagnostic accuracy, did not significantly improve (P = 0.62). In HPV-related disease (n = 32), there was no significant difference between SUV1, SUV2, and RI in malignant and benign nodes, yet this subgroup was small. CONCLUSIONS: DTPI did not improve the overall diagnostic accuracy of FDG-PET/CT to detect residual disease 12 weeks after chemoradiation. Due to differences in tracer kinetics between malignant and benign nodes, DTPI improved the specificity, but at the expense of a loss in sensitivity, albeit minimal. Since false negatives at the 12 weeks PET/CT are mainly due to minimal residual disease, DTPI is not able to significantly improve sensitivity, but repeat scanning at a later time (e.g. after 12 months) could possibly solve this problem. Further study is required in HPV-associated disease.
RESUMEN
The traditional concept of post-treatment surveillance in head and neck cancer patients relies on examinations directed at early detection of disease recurrence and/or second primary tumors. They are usually provided by ear, nose and throat specialists with complementary input from radiation oncologists and medical oncologists. Emerging evidence underscores the importance of monitoring and effective management of late adverse events. One of the major drawbacks is a lack of prospective controlled data. As a result, local institutional policies differ, and practice recommendations are subject to continuing debate. Due to the economic burden and impact on emotional comfort of patients, intensity and content of follow-up visits are a particularly conflicting topic. According to the current evidence-based medicine, follow-up of head and neck cancer patients does not prolong survival but can improve quality of life. Therefore, an approach giving priority to a multidisciplinary care involving a speech and swallowing expert, dietician, dentist, and psychologist may indeed be more relevant. Moreover, on a case-by-case basis, some patients need more frequent consultations supplemented by imaging modalities. Human papillomavirus positive oropharyngeal cancer tends to develop late failures at distant sites, and asymptomatic oligometastatic disease, especially in the lungs, can be successfully salvaged by local ablation, either surgically or by radiation. The deep structures of the skull base related to the nasopharynx are inaccessible to routine clinical examination, advocating periodic imaging supplemented by nasofibroscopy as indicated. Anamnesis of heavy smoking justifies annual low-dose computed tomography screening of the thorax and intensive smoking cessation counseling. Finally, some cancer survivors feel more comfortable with regular imaging, and their voice should be taken into consideration. Future development of surveillance strategies will depend on several variables including identification of reliable predictive factors to select those who could derive the most benefit from follow-up visits, the availability of long-term follow-up data, the results of the first randomized trials, resource allocation patterns, infrastructure density, and the therapeutic landscape of locally advanced and recurrent and/or metastatic disease, which is rapidly changing with the advent of immune checkpoint inhibitors and better utilization of local approaches.
RESUMEN
BACKGROUND: Dysphagia is a common and serious complication after (chemo)radiotherapy (CRT) for head-and-neck cancer (HNC) patients. Prophylactic swallowing exercises (PSE) can have a significantly positive effect on post-treatment swallowing function. However, low adherence rates are a key issue in undermining this positive effect. This current randomized trial will investigate the effect of adherence-improving measures on patients' swallowing function, adherence and quality of life (QOL). METHODS: This ongoing trial will explore the difference in adherence and swallowing-related outcome variables during and after PSE in HNC patients performing the same therapy schedule, receiving different delivery methods. One hundred and fifty patients treated in various hospitals will be divided into three groups. Group 1 performs PSE at home, group 2 practices at home with continuous counseling through an app and group 3 receives face-to-face therapy by a speech and language pathologist. The exercises consist of tongue-strengthening exercises and chin-tuck against resistance with effortful swallow. The Iowa Oral Performance Instrument and the Swallowing Exercise Aid are used for practicing. Patients are evaluated before, during and after treatment by means of strength measurements, swallowing and QOL questionnaires. DISCUSSION: Since low adherence rates undermine the positive impact of PSE on post-treatment swallowing function, there is need to develop an efficient PSE protocol maximizing adherence rates.

BACKGROUND: Concomitant chemotherapy and radiotherapy (chemoradiation; CRT) is the standard treatment for locoregionally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). CRT improves local control and overall survival (OS) when compared to radiotherapy (RT) alone. Induction chemotherapy (IC) reduces the risk of distant metastases (DM) and improves OS by 5% with the use of cisplatin/infusional 5 fluorouracil (PF) in meta-analysis. Adding a taxane to PF in the IC regimen confers a better outcome. Sequential treatment (ST) of IC followed by CRT is therefore under active investigation in multiple phase III trials. METHODS: We compared the outcome of two cohorts of patients (pts) with LA-SCCHN treated at our institution with CRT (n = 27) or ST (n = 31), respectively. CRT consisted of GEM 100 mg/m2 weekly + conventional RT (70 Gy); ST consisted of the same CRT preceded by platinum-based IC. RESULTS: Response to IC: complete 8 (26%), partial 20 (65%), stable 1, progressive 1, not evaluable 1. Median follow up of the surviving pts: for CRT 73 months, for ST 51 months. Median time to distant metastasis (TDM) was for CRT 23.6 months, for ST not reached. Median OS was for CRT 20.2 months, for ST 40.2 months. Cox regression analysis, taking into account age, T and N stage and tumor site, showed a hazard ratio with ST of 1.190 for time to locoregional failure (p = 0.712), 0.162 for TDM (p = 0.002), and 0.441 for overall survival (OS) (p = 0.026). CONCLUSION: TDM and OS were found significantly longer in the ST cohort without a reduced locoregional control. Notwithstanding the limitations of a non-randomized single-center comparison, the results are in line with very preliminary data of randomized comparisons suggesting an improved outcome with ST.

BACKGROUND: Radiation-associated-dysphagia is a serious side effect of radiotherapy (RT) for head and neck cancer (HNC). METHODS: Seventy-six patients had a weekly prospective follow-up from baseline until one week post-RT. Combined mixed model analysis (n = 43) determined the evolution of self-perceived swallowing function, isometric tongue strength (MIP), tongue strength (TS) during swallowing (Pswal), and quality of life (QoL) in these patients during RT. RESULTS: Swallowing deteriorated from the third week on, resulting in an increase of tube dependency from 10% at baseline toward 31% post-RT. Both MIP and Pswal are reduced, with anterior MIP decreasing in 29% of patients and posterior MIP in 17%. Pswal decreases for saliva and a bolus swallow. All QoL subscales except "sleep" were affected during RT. CONCLUSIONS: Self-perceived swallowing function, TS and QoL decrease during RT for HNC. Current findings highlight the need for early monitoring of these parameters.

BACKGROUND: Sudden sensorineural deafness is a well-known symptom mostly of unknown etiology. CASE DESCRIPTION: A case of sudden sensorineural deafness is reported to be caused by a small, remote, ipsilateral tentorial meningioma not compressing the vestibulocochlear nerve or auditory tract. Surgical resection of the meningioma immediately restored the patient's hearing. CONCLUSION: The authors hypothesize that the sudden sensorineural deafness resulted from a growing meningioma inducing a neurovascular compression of the vestibulocochlear nerve, the vertebral artery already being in close relationship with the vestibulocochlear nerve in the premorbid phase. Resection of the meningioma allows for an autodecompression of this vascular conflict resulting in hearing restoration.

We present the case of a 39-year-old man with a severe glottis stenosis. The saddle nose, images of laryngotracheal stenosis and the (FDG) positron-emission tomography/computed tomography lead to a final diagnosis of relapsing polychondritis. In the patient a coexistent myelodysplastic syndrome was diagnosed. Moreover, the elevated total IgG4 exceeding 135 ml/dl requested additional immunochemistry for detection of IgG4-bearing plasma cells in the biopsies. The patient underwent an allogenic stem cell transplantation and died on day 40 after the transplantation because of an acute steroid-resistent graft vs host.

Purpose To assess the standardized implementation and reporting of surveillance [18F]fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scan of the neck in locoregionally advanced head-and-neck squamous cell carcinoma (LAHNSCC) after concurrent chemoradiotherapy (CCRT). Patients and Methods We performed a prospective multicenter study of FDG-PET/CT scanning 12 weeks after CCRT in newly diagnosed patients with LAHNSCC (stage IVa/b) that used standardized reconstruction and Hopkins reporting criteria. The reference standard was histology or > 12 months of clinical follow-up. The primary outcome measure was the negative predictive value (NPV) of FDG-PET/CT scans and other supporting diagnostic test characteristics, including time dependency with increasing follow-up time. Results Of 152 patients, 125 had adequate primary tumor control after CCRT and entered follow-up (median, 20.4 months). Twenty-three (18.4%) had residual neck disease. Overall, NPV was 92.1% (95% CI, 86.9% to 95.3%; null hypothesis: NPV = 85%; P = .012) with sensitivity of 65.2% (95% CI, 44.9% to 81.2%), specificity of 91.2% (95% CI, 84.1% to 95.3%), positive predictive value of 62.5% (95% CI, 45.5% to 76.9%), and accuracy of 86.4% (95% CI, 79.3% to 91.3%). Sensitivity was time dependent and high for residual disease manifesting up to 9 months after imaging but lower (59.7%) for disease detected up to 12 months after imaging. Standardized reporting criteria reduced the number of equivocal reports (95% CI for the difference, 2.6% to 15.0%; P = .003). Test characteristics were not improved with the addition of lymph node CT morphology criteria. Conclusion FDG-PET/CT surveillance using Hopkins criteria 12 weeks after CCRT is reliable in LAHNSCC except for late manifesting residual disease, which may require an additional surveillance scan at 1 year after CCRT to be detected.

BACKGROUND: Reduced tongue strength is an important factor contributing to early and late dysphagia in head and neck cancer patients previously treated with chemoradiotherapy. The evidence is growing that tongue strengthening exercises can improve tongue strength and swallowing function in both healthy and dysphagic subjects. However, little is known about the impact of specific features of an exercise protocol for tongue strength on the actual outcome (strength or swallowing function). Previous research originating in the fields of sports medicine and physical rehabilitation shows that the degree of exercise load is an influential factor for increasing muscle strength in the limb skeletal muscles. Since the tongue is considered a muscular hydrostat, it remains to be proven whether the same concepts will apply. METHODS/DESIGN: This ongoing randomized controlled trial in chemoradiotherapy-treated patients with head and neck cancer investigates the effect of three tongue strengthening exercise protocols, with different degrees of exercise load, on tongue strength and swallowing. At enrollment, 51 patients whose dysphagia is primarily related to reduced tongue strength are randomly assigned to a training schedule of 60, 80, or 100% of their maximal tongue strength. Patients are treated three times a week for 8 weeks, executing 120 repetitions of the assigned exercise once per training day. Exercise load is progressively adjusted every 2 weeks. Patients are evaluated before, during and after treatment by means of tongue strength measurements, fiber-optic endoscopic evaluation of swallowing and quality-of-life questionnaires. DISCUSSION: This randomized controlled trial is the first to systematically investigate the effect of different exercise loads in tongue strengthening exercise protocols. The results will allow the development of more efficacious protocols. TRIAL REGISTRATION: Current Controlled Trials ISRCTN14447678.

BACKGROUND: Targeted therapy against the Epidermal Growth Factor Receptor (EGFR) is among the most promising molecular therapeutics for Head and Neck Squamous Cell Carcinoma (HNSCC). However, drug resistance limits the clinical efficacy of anti-EGFR monoclonal antibodies and no predictive biomarker has entered the clinic yet. METHODS: A retrospective clinical study was performed utilizing pathological specimens from 52 newly diagnosed HNSCC patients. These patients were screened for mutations in EGFR and KRAS. Tyrosine kinase mutations in EGFR and KRAS mutations were evaluated by high resolution melting analysis (HRMA), whereas EGFRvIII was determined using one-step real-time PCR. Finally, patient samples were screened for HPV-DNA by GP5+/6+ PCR. Survival analysis was performed using Kaplan-Meier analysis and significance was calculated using log-rank statistic. RESULTS: In our study population no EGFRvIII mutations were present. However, two silent mutations were found; T785T in exon 20 and R836R in exon 21 of the EGFR gene. Additionally, HRMA revealed an abnormal KRAS melting pattern in 7.0% of the samples. However, the KRAS StripAssay could confirm only one sample with a G12S mutation and none of these samples could be confirmed by direct sequencing. HPV DNA was present in 3/25 larynx and 9/27 oropharynx tumors. CONCLUSION: The low rate of EGFR and KRAS mutations in this Belgian HNSCC population suggests that these genes will probably not play a major role in predicting response to anti-EGFR therapy in HNSCC. Hence, other predictive markers need to be discovered in order to optimize EGFR targeting therapy.

BACKGROUND: Docetaxel, ifosfamide and cisplatin have all shown activity in squamous cell carcinoma of the head and neck (SCCHN). The optimal combination of the three drugs is, however, unknown. Considering the favorable results of taxane-containing triplets as induction chemotherapy in locally advanced (LA) SCCHN, DIP (docetaxel, ifosfamide, cisplatin) was studied in this setting as part of a phase I dose- and sequence-exploring study. PATIENTS AND METHODS: D (60 or 75 mg/m(2)) was given by 60-min infusion on day 1, I (1000 mg/m(2)/day), with mesna until 12 hours after I, by 24-h infusion days 1-5, and P (50 or 75 mg/m(2)) by 24-h infusion on days 1 or 5. The cycles were repeated every 21 days. Toxicities according to the National Cancer Institute Common Toxicity Criteria version 2 (NCI-CTC2) were evaluated weekly and response was evaluated every 2 cycles according to the World Health Organization (WHO) criteria. Thereafter, radiotherapy (RT, cumulative dose 70 Gy) or chemoradiation (CRT), both with conventional fractionation, were planned. RESULTS: Twenty-two patients (18 male, 4 female; age 41-66 years, performance status 0-1, 2 T4N0, 3 T3N2, 11 T4N2, 3 T unknown N3, 1 T1N3 and 2 T4N3) received a median of 4 DIP cycles (range 1-5). Grade 4 neutropenia occurred in 18 patients, grade 3 and 4 thrombocytopenia in 5 and 1 patients, respectively, and grade 3 anemia in 5 patients. Gastrointestinal and mucosal toxicities were generally mild/moderate. Vascular complications (probably not DIP-related) precluded local treatment in two patients. Moreover, one patient died on day 13 of the first DIP (neutropenic sepsis and myocardial infarction). The remaining patients received RT (n=2) or CRT (n=17; 16 of these with gemcitabine). The response to 2 x DIP was 95% (1 complete response, 19 partial responses, 1 stable disease); the complete response rate increased to 42% after 4 x DIP. No dose or sequence effect was evident. The minimum follow-up of the surviving patients was 51 months, with median relapse-free survival of 13.8 months and median overall survival of 18.8 months. Only four patients relapsed at distant sites. CONCLUSION: DIP is highly active in previously untreated LA SCCHN, however, toxicity of DIP in this population is substantial.
