RESUMEN
PURPOSE: Intestinal-type adenocarcinoma (ITAC) is a rare sinonasal malignancy. Curative treatment requires multidisciplinary approach, with surgical options consist of the endonasal endoscopic approach (EEA) and external surgery (EXTS). Here, we provide the post-operative and survival results from a single-center long-term follow-up. METHODS: We report long-term follow-up of 92 ITAC cases treated between 1998 and 2018, treated with EEA (n = 40) or EXTS (n = 52). Survival estimates, post-operative complications and duration of hospitalization were compared between surgical modalities. RESULTS: Baseline characteristics were similar. A higher number of T4b tumors (16%), and subsequently more tumoral invasion (39%), was present in patients undergoing EXTS compared to EEA (3% and 18%, respectively). No difference in Barnes histology subtypes was noticed. Patients undergoing EEA had a shorter post-operative hospitalization stay versus EXTS (4 versus 7 days). Use of EEA was associated to improved disease-specific survival (DSS; 11.4 versus 4.4 years; HREEA = 0.53), especially for patients with T3-4a tumors (11.4 versus 3.0 years; HREEA = 0.41). Patients with T3-4 stage, tumoral invasion, positive surgical margins, mucinous or mixed histology, and prolonged post-operative hospital stay showed poor local relapse-free, disease-free, overall, and DSS. CONCLUSIONS: Long-term follow-up in locally advanced ITAC demonstrates that resection by EEA is correlated with improved DSS compared to EXTS, especially for T3-4 tumors. No significant differences between both treatment modalities was observed regarding per- and post-operative complications, although hospitalization in patients undergoing EEA was shorter than for patients treated with EXTS. These results confirm that EEA should remain the preferred surgical procedure in operable cases of sinonasal ITAC.

Pheochromocytomas (PHEO) and paragangliomas (PGL) can occur sporadic or within genetic predisposition syndromes. Despite shared embryology, there are important differences between PHEO and PGL. The aim of this study was to describe the clinical presentation and disease characteristics of PHEO/PGL. A retrospective analysis of consecutively registered patients diagnosed with or treated for PHEO/PGL in a tertiary care centre was performed. Patients were compared according to anatomic location (PHEO vs PGL) and genetic status (sporadic vs hereditary). In total, we identified 38 women and 29 men, aged 50 ± 19 years. Of these, 42 (63%) had PHEO, and 25 (37%) had PGL. Patients with PHEO presented more frequently with sporadic than hereditary disease (45 years vs 27 (77%) vs 8 (23%)) than patients with PGL (9 (36%) vs 16 (64%), respectively) and were older at diagnosis (55 ± 17 vs 40 ± 18 years, P = 0.001), respectively). About half of the cases in both PHEO and PGL were diagnosed due to disease-related symptoms. In patients with PHEO, tumour diameter was larger (P = 0.001), metanephrine levels higher (P = 0.02), and there was more frequently a history of cardiovascular events than in patients with PGL. In conclusion, we found that patients with PGL more frequently have a hereditary predisposition than those with PHEO, contributing to the fact that diagnosis is generally made earlier in PGL. Although diagnosis in both PHEO and PGL was mostly due to related symptoms, patients with PHEO more often presented with cardiovascular comorbidities than those with PGL which might relate to a higher number of functionally active tumours in the former.
RESUMEN
PURPOSE: Recent technical advancements in PET imaging have improved sensitivity and spatial resolution. Consequently, clinical nuclear medicine will be confronted with PET images on a previously unfamiliar resolution. To better understand [18F]FDG distribution at submillimetric scale, a direct correlation of radionuclide-imaging and histopathology is required. METHODS: A total of five patients diagnosed with a malignancy of the head and neck were injected with a clinical activity of [18F]FDG before undergoing surgical resection. The resected specimen was imaged using a preclinical high-resolution PET/CT, followed by slicing of the specimen. Multiple slices were rescanned using a micro-PET/CT device, and one of the slices was snap-frozen for frozen sections. Frozen sections were placed on an autoradiographic film, followed by haematoxylin and eosin staining to prepare them for histopathological assessment. The results from both autoradiography and histopathology were co-registered using an iterative co-registration algorithm, and regions of interest were identified to study radiotracer uptake. RESULTS: The co-registration between the autoradiographs and their corresponding histopathology was successful in all specimens. The use of this novel methodology allowed direct comparison of autoradiography and histopathology and enabled the visualisation of uncharted heterogeneity in [18F]FDG uptake in both benign and malignant tissue. CONCLUSION: We here describe a novel methodology enabling the direct co-registration of [18F]FDG autoradiography with the gold standard of histopathology in human malignant tissue. The future use of the current methodology could further increase our understanding of the distribution of radionuclides in surgically excised malignancies and hence, improve the integration of pathology and molecular imaging in a multiscale perspective.

BACKGROUND: The clinical significance of tumor-infiltrating lymphocytes (TILs) and programmed cell death-ligand 1 (PD-L1) expression has been thoroughly researched in squamous cell carcinoma of the head and neck (SCCHN). To address the impact of intra- and intertumoral heterogeneity in these biomarkers, we explored the concordance of PD-L1 combined positive score (CPS) and stromal TILs in different paired tissue sample types, while evaluating their internal relationship and prognostic impact. METHODS: A total of 165 tissue blocks from 80 SCCHN patients were reviewed for TILs and PD-L1 CPS. Concordance between paired tissue samples was evaluated, and their association with several clinicopathological variables, overall survival (OS), and disease-free survival (DFS) was determined. RESULTS: Biopsies and paired resection material were severely discordant in 39% and 34% of samples for CPS and TIL count, respectively, of which CPS was underscored in 27% of biopsies. In paired primary tumor-metastatic lesions, the disagreement was lower for CPS (19%) but not for TIL count (44%). PD-L1 CPS was correlated with prolonged OS when calculated from tissue acquirement, while extended OS and DFS were observed for high TIL density. CONCLUSION: Intertumoral and, especially, intratumoral heterogeneity were confounding factors when determining PD-L1 CPS and TIL count on paired tissue samples, indicating the increasing necessity of assessing both biomarkers on representative tissue material. Although TILs hold valuable prognostic information in SCCHN, the robustness of PD-L1 as a biomarker in SCCHN remains ambiguous.
RESUMEN
The surgical treatment of head and neck malignancies relies on the complete removal of tumoral tissue, while inadequate margins necessitate the use of adjuvant therapy. However, most positive margins are identified postoperatively as deep margins, and intraoperative identification of the deep positive margins could help achieve adequate surgical margins and decrease adjuvant therapies. To improve deep-margin identification, we investigated whether the use of high-resolution preclinical PET and CT could increase certainty about the surgical margins in three dimensions. Patients with a malignancy of the head and neck planned for surgical resection were administered a clinical activity of 4MBq/kg 18F-FDG approximately one hour prior to surgical initiation. Subsequently, the resected specimen was scanned with a micro-PET-CT imaging device, followed by histopathological assessment. Eight patients were included in the study and intraoperative PET/CT-imaging of 11 tumoral specimens and lymph nodes of three patients was performed. As a result of the increased resolution, differentiation between inflamed and dysplastic tissue versus malignant tissue was complicated in malignancies with increased peritumoral inflammation. The current technique allowed the three-dimensional delineation of 18F-FDG using submillimetric PET/CT imaging. While further optimization and patient stratification is required, clinical implementation could enable deep margin assessment in head and neck resection specimens.
RESUMEN
An increased presence of CD206-expressing tumor associated macrophages in solid cancers was proposed to be associated with worse outcomes in multiple types of malignancies, but contradictory results are published. We performed a reproducible systematic review and meta-analysis to provide increased evidence to confirm or reject this hypothesis following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The Embase, Web of Science, and MEDLINE-databases were systematically searched for eligible manuscripts. A total of 27 papers studying the prognostic impact of CD206 in 14 different tumor types were identified. Meta-analyses showed a significant impact on the overall survival (OS) and disease-free survival (DFS). While no significant differences were revealed in progression-free survival (PFS) and disease-specific survival (DSS), a shift towards negative survival was correlated with increased CD206-expresion. As a result of the different tumor types, large heterogeneity was present between the different tumor types. Subgroup analysis of hepatocellular carcinoma and gastric cancers revealed no heterogeneity, associated with a significant negative impact on OS in both groups. The current systematic review displays the increased presence CD206-expressing macrophages as a significant negative prognostic biomarker for both OS and DFS in patients diagnosed with solid cancers. Because a heterogenous group of tumor types was included in the meta-analysis, the results cannot be generalized. These results can, however, be used to further lead follow-up research to validate the specific prognostic value of CD206 in individual tumor types and therapeutic approaches.
RESUMEN
Tumour infiltrating lymphocytes (TILs) have been described as a biomarker for the host immune response against the tumour with prognostic properties. The International Immuno-Oncology Biomarkers Working Group (IBWG) proposed a standardised method for quantifying TILs in solid tumours to improve consistent and reproducible scoring. In this study, the methodology was tested in a retrospective population of oropharyngeal squamous cell carcinoma (OPSCC). TIL quantification was performed on 92 OPSCC samples (2004-2013) by four independent observers as described by the IBWG. Interobserver variability was assessed and results were correlated with clinicopathological variables and survival. TIL evaluation turned out to be challenging in OPSCC due to heterogeneity of TILs distribution, presence of pre-existing lymphoid tissue, surface ulceration or erosion and insufficient amount of intertumoural stroma in biopsies. Nonetheless, interobserver variability proved to be good to excellent. High stromal TILs (TILstr) and intratumoural TILs (TILtum) were both correlated to favourable overall survival and multivariate analysis showed TILstr to be the sole independent prognostic factor in OPSCC. The IBWG-proposed TIL quantification method is feasible and reproducible in OPSCC and provides valuable prognostic information regarding clinicopathological characteristics and overall survival. The use of this standardised methodology may facilitate implementation of TILs scoring as a prognostic biomarker in OPSCC.

PURPOSE: This study investigates the long-term voice outcome of thyroidectomy up to 10 years after the surgery using a longitudinal prospective study design. METHODS: Eighteen participants (6 men and 12 women, mean age: 54 years) who underwent a thyroidectomy between September 2006 and May 2007 were included in this study. A voice assessment protocol consisting of subjective (videolaryngostroboscopic evaluation, auditory- perceptual evaluation, patients' self-report) and objective voice assessments (maximum performance task, acoustic analysis, voice range profile and Dysphonia Severity Index) was used to evaluate the participants' pre- and postoperative voice. Voice measurements were compared before and one week, six weeks, three months and 10 years after the surgery. RESULTS: No significant differences over time in auditory-perceptual and objective voice parameters were found, except for shimmer. Only in the first postoperative condition, significantly more patients reported vocal complaints. A progressive amelioration of the vocal folds' movement patterns was observed in the postoperative conditions. CONCLUSION: The findings of this small longitudinal prospective study suggest that thyroidectomy without laryngeal nerve injury does not cause a permanent deterioration of the laryngeal aspect or function, vocal fold behavior and the self-perceived, perceptual and objective vocal quality. The increase of the shimmer 10 years post-thyroidectomy may be related to vocal aging.

Background and aim: Verrucous hyperplasia (VH) and verrucous carcinoma (VC) of the head and neck are two (pre)malignant entities that are slowly progressive with low tendency to metastasize. However, they can reduce the patient's Quality of Life (QoL) and may even transform into squamous cell carcinoma (SCC). As they are typically approached by surgical resection, some patients do not qualify for surgery. Methotrexate may be a systemic alternative but the response is mostly not durable. This case report tries to illustrate the potential role of methotrexate in VH/VC of the head and neck.Method: We describe four cases of patients with VH or VC of the head and neck who received methotrexate (40-60 mg/m2) in a weekly or two-weekly interval.Results: Two patients received methotrexate in a neoadjuvant setting. The first patient achieved a macroscopical complete response after 16 cycles and remained in remission after surgery. The second patient suffered from residual disease after 26 cycles and refused radical surgery.Two other patients refused surgery at the time of diagnosis and were proposed methotrexate as a salvage treatment. The first patient had an ongoing response on methotrexate after >60 cycles. The second patient achieved macroscopical complete remission after 28 cycles of methotrexate but suffered relapse by developing an oropharyngeal SCC in the same region.Conclusion: When surgery is not desirable in VH and/or VC, patients can be treated with methotrexate which has a reasonable effect and seems to be well tolerated. Nevertheless, surgery should be the preferred strategy to achieve complete remission.

OBJECTIVE: We aimed to analyze oncologic outcomes and identify patterns of failure and negative prognostic factors in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx. METHODS: This was a retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018 for residual/recurrent/second primary SCC in the larynx or hypopharynx after initial (chemo)radiation. Prognostic factors for oncologic outcomes were identified using univariable and multivariable analysis. RESULTS: A total of 405 patients were included in the final analysis. Five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), and locoregional relapse-free survival (LRFS) estimates were 47.7% (95% confidence interval [CI] 42.0-53.2%), 68.7% (95% CI 63.7-73.7%), 42.1% (95% CI 36.7-47.4%), and 44.3% (95% CI 38.8-49.7%), respectively. In a multivariable model, increasing clinical tumor stage of the residual/recurrent/second primary tumor, increasing number of metastatic cervical lymph nodes retrieved during neck dissection, hypopharyngeal and supraglottic tumor location, positive section margin status and perineural invasion were independent negative prognostic variables for OS, DSS, DFS, and LRFS. The type of second tumor was identified as an additional independent prognosticator for DSS, with local recurrences and second primary tumors having a better prognosis than residual tumor. CONCLUSIONS AND RELEVANCE: Favorable oncologic outcomes are reported after STL. Increasing clinical tumor stage, increasing number of metastatic cervical lymph nodes, hypopharyngeal and supraglottic tumor location, positive section margins, and perineural invasion are identified as independent negative prognosticators for all oncologic outcome measures.

Background/Purpose: We analyzed complications and functional outcomes and aimed at identifying prognostic factors for functional outcomes and complications in patients who underwent salvage total laryngectomy (STL) for residual, recurrent, and second primary squamous cell carcinoma (SCC) of the larynx and hypopharynx after initial (chemo)radiation. Methods: Retrospective cohort study of patients who underwent STL in four major Belgian reference hospitals between 2002 and 2018. Prognostic factors for functional outcomes and complications were identified with uni- and multivariable analysis. Results: A total of 405 patients were included in the final analysis. STL was performed for residual tumor (40.2%), local recurrence (40.5%), or second primary laryngeal or hypopharyngeal SCC (19.4%). Early postoperative complications were experienced by 34.2% of patients: postoperative hemorrhage occurred in 5.4%, wound infection in 16.2%, and clinical pharyngocutaneous fistula (PCF) in 25.5% of patients. Early readmission proved necessary in 15.1% of cases, most often due to late PCF development (72.2%). Patients achieved total peroral intake in 94.2% of cases. However, subjective dysphagia was reported by 31.3% of patients during follow-up. Functional speech, defined as functional communication by speech without additional aids, was reported in 86.7% of cases and was most often achieved by tracheo-esophageal puncture (TEP) (94.1%). In a multivariable model, lower preoperative hemoglobin (<12.5 g/dl) was identified as an independent prognostic factor for higher overall complication rate. No risk factors were found significant for clinical fistula formation. Vascularized tissue augmentation did not significantly prevent clinical PCF. Patients with positive section margins, patients initially treated with surgery combined with adjuvant RT (vs. radiotherapy alone), and those developing PCF after STL were less likely to achieve total peroral intake. Postoperative dysphagia proved more likely in patients who developed a PCF postoperatively, and less likely in patients who underwent STL without partial pharyngectomy and in patients with myocutaneous pectoralis major (PM) flap reconstruction, compared to muscle onlay PM flap. Achieving postoperative functional speech proved most likely in patients with smaller tumors (lower pT classification) and free section margins. Conclusion: Substantial complication rates and favorable functional outcomes are reported after STL.
RESUMEN
CASE PRESENTATION: We report for the first time a synchronous papillary and follicular thyroid carcinoma in a 12-year-old girl presenting with a large (5 cm diameter) left thyroid nodule, an increased left and right upper pole technetium tracer uptake at scintigraphy and hyperthyroidism. The uptake at the right lobe was explained by the crossing of the left nodule to the right site of the neck at Computed Tomography (CT) scanning. BACKGROUND: Although thyroid nodules are less common in children than in adults, there is more vigilance required in children because of the higher risk of malignancy. According to literature, about 5% of the thyroid nodules in adults are malignant versus 20-26% in children. The characteristics of 9 other pediatric cases with a differentiated thyroid carcinoma presenting with a toxic nodule, which have been reported during the last 20 years, are summarized. A nodular size of more than 3.5 cm and female predominance was a common finding. CONCLUSIONS: The presence of hyperthyroidism in association with a hyperfunctioning thyroid nodule does not rule out thyroid cancer and warrants careful evaluation, even in the absence of cervical lymph node invasion.
RESUMEN
PURPOSE: Sublingual hematoma is a rare complication seen in bleeding disorders, trauma, dental procedures, and the use of anticoagulants. Only a few publications have described idiopathic spontaneous sublingual hematoma, and all of them suspected severe hypertension as etiology. Our objective is to present a case of idiopathic spontaneous sublingual hematoma in a 48-year-old patient without any medical history of hypertension and to perform a literature review on this subject. METHODS: Case report presentation based on information extracted from the electronic patient database of Ghent University Hospital including a literature review of sublingual hematoma. RESULTS: This case report describes a 48-year-old male patient presenting with a spontaneous sublingual hematoma, which needed to be treated with an urgent tracheotomy. Drainage of the old hematoma followed 11 days later. He was not known with hypertension or any bleeding disorder. Clinical examination using fiberoptic nasolaryngoscopy, a CT scan, MRI scan, and biopsy of the sublingual salivary gland showed no focus for etiology. CONCLUSIONS: Clinical work-up is necessary to look for a cause of a spontaneous sublingual hematoma. Idiopathic spontaneous hematoma is only a rare entity. Aggressive airway management should be the first step in treatment. To date, there is no consensus about the management regarding the hematoma itself. Mostly, clinicians start with observation for spontaneous resolution of the hematoma and when possible to treat causative factors. Surgical drainage is performed when conservative treatment is not sufficient.

BACKGROUND: Acute and late toxicity after intensity-modulated radiotherapy (IMRT) for head and neck cancer (HNC) impacts on patient quality of life; yet, very late toxicity data remain scarce. This study assessed dysphagia, xerostomia, and neck fibrosis 3-8 years after IMRT. METHODS: A retrospective analysis using generalized estimated equations was performed on 60 patients with HNC treated with fractionated IMRT between 2000 and 2015 who had a follow-up ≥8 years. Toxicity was scored using LENT-SOMA scales. RESULTS: A trend towards a nonlinear global time effect (P = .05) was noted for dysphagia with a decrease during the 5 years post-treatment and an increase thereafter. A significant decrease in xerostomia (P = .001) and an increase in neck fibrosis (P = .04) was observed until 8 years. CONCLUSIONS: Dysphagia, xerostomia, and neck fibrosis do not appear stable over time and remain highly prevalent in the very late follow-up. Our findings support the need for prospective trials investigating very late toxicity in patients with HNC.

OBJECTIVES: After oesophagectomy, stomach grafts are most frequently used to restore intestinal continuity. Less frequently, a colonic graft is used. There is quite a large body of literature addressing the functional outcome after gastric pull-up, but little is known about the functional results of colonic interposition (CI). The aim of this study was to assess the short-term outcomes and the long-term quality of life and function of the CI postoesophagectomy. METHODS: Between 2002 and 2016, we retrospectively collected data on 80 patients with CI from personal health records at the Ghent University hospital. We prospectively compared the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-OG25 and Swallowing Quality of Life (SWAL-QOL) questionnaire scores to the healthy reference group and the gastric tube (GT) group. RESULTS: The 30-day mortality rate was 5%. Anastomotic leakage occurred in 37.5% and stenosis in 20% of the patients. The median overall survival of all patients was 33.9 months (95% confidence interval 8.3-59.4). The mean general health score of the CI patients was less than the healthy reference group but comparable to the GT group (CI = 62.1 vs healthy reference group = 71.2 vs GT = 60). Fifty percent of the patients reported their health as good and 15% as very good. The mean functional results with a CI were better than with a GT. Compared to GT patients, CI patients had less dyspnoea, reflux and dysphagia, but they reported more food selection, diarrhoea and weight loss. CONCLUSIONS: Despite the high complication rate, the severity of the disease and the demanding operation, patients perceived themselves as being in good health and reported very good long-term functionality after CI.

BACKGROUND: To identify predictive factors for the development of late grade 4 mucosal ulcers in adaptive dose-escalated treatments for head-and-neck cancer. MATERIAL AND METHODS: Patient data of four dose-escalated three-phase adaptive dose-painting by numbers (DPBN) clinical trials were analyzed in this study. Correlations between the development of late grade 4 ulcers and factors related with the treatment, disease characteristics and the patient were investigated. Dosimetrical thresholds were searched among the highest doses received by 1.75 cm3 (D1.75cc) of the primary gross tumor volume (GTVT) and the corresponding normalized isoeffective dose (NID21.75cc, with a reference dose of 2Gy/fraction and α/ß of 3 Gy). RESULTS: From 39 studied patients, nine developed late grade 4 mucosal ulcers. The continuation to either smoke or drink alcohol after therapy was the factor that showed a strong (eight out of nine patients) association with the occurrence of grade 4 ulcers. Six of the patients who continued to smoke or/and drink had D1.75cc and NID21.75cc above 84 Gy and 95.5 Gy, respectively. Seven of the patients with grade 4 had the dose levels above these thresholds, but even if the D1.75cc threshold was significant in the prediction of late grade 4 ulcers, it could not be considered as the only contributing factor. CONCLUSIONS: The search for patterns provided strong reasons to apply a dosimetrical threshold for the peak-dose volume of 1.75 cm3 as a preventive measure for late grade 4 mucosal ulcers. Also, patients that continue to smoke or drink alcohol after therapy have increased risk to develop late mucosal ulcers.
