The Impact of the COVID-19 Pandemic on Incidence and Short-Term Survival for Common Solid Tumours in the United Kingdom: A Cohort Analysis.

Purpose: The COVID-19 pandemic profoundly affected healthcare systems and patients. There is a need to comprehend the collateral effects of the pandemic on non-communicable diseases. We examined the impact of the pandemic on short-term survival for common solid tumours, including breast, colorectal, head and neck, liver, lung, oesophageal, pancreatic, prostate, and stomach cancer in the UK. Methods: This was a population-based cohort study of electronic health records from the UK primary care Clinical Practice Research Datalink GOLD database. In sum, 12,259,744 eligible patients aged ≥18 years with ≥1 year's history identified from January 2000 to December 2022 were included. We estimated age-standardised incidence and short-term (one- and two-year) survival for several common cancers from 2000 to 2019 (in five-year strata) and compared these to 2020-2022 using the Kaplan-Meier method. Results: Incidence decreased for most cancers in 2020 and recovered to different extents in 2021-2022. Short-term survival improved for most cancers between 2000 and 2019, but then declined, albeit minimally, for those diagnosed in 2020-2022. This was most pronounced for colorectal cancer, with one-year survival falling from 78.8% (95% CI 78%-79.6%) in 2015-2019 to 77% (95% CI 75.6-78.3%) for those diagnosed in 2020-2022. Conclusion: Short-term survival for many cancers was impacted, albeit minimally, by the pandemic in the UK, with reductions in survivorship from colorectal cancer equivalent to returning to the mortality seen in the first decade of the 2000s. While data on longer-term survival are needed to fully comprehend the impact of COVID-19 on cancer care, our findings illustrate the need for an urgent and substantial commitment from the UK National Health Service to address the existing backlog in cancer screening and diagnostic procedures to improve cancer care and mortality.

Predictive capacity for local disease control of neogenin-1 (NEO1) transcriptional expression in patients with head and neck squamous cell carcinoma.

PURPOSE: To analyze the predictive capacity for local disease control of the transcriptional expression of neogenin-1 (NEO1) gene in patients with head and neck squamous cell carcinoma (HNSCC). METHODS/PATIENTS: A retrospective study was performed on tumor biopsies from 107 patients with HNSCC treated surgically. The transcriptional expression of NEO1 was determined by RT-PCR. NEO1 transcriptional expression value was categorized according to local disease control by recursive partitioning analysis. RESULTS: Lower NEO1 transcriptional expression was associated with worse local control after surgical treatment. Patients with lower NEO1 expression (n = 25, 23.4%) had a 5-year local recurrence-free survival of 61.8% (95% CI: 42.1-81.5%), while patients with higher NEO1 expression (n = 82, 76.6%) had a 5-year local recurrence-free survival of 85.6% (95% CI: 77.6-93.6%), (P = 0.003). According to the result of multivariable analysis, patients with lower NEO1 expression had a 2.7-fold increased risk of local tumor recurrence (95% CI: 1.0-7.0, P = 0.043) compared to patients with higher NEO1 expression. CONCLUSIONS: HNSCC patients with a lower transcriptional expression of NEO1 have a significantly higher risk of local recurrence after surgical treatment.

The current situation of tutoring in specialised training in otorhinolaryngology-head and neck surgery in Spain. Where are we? Where do we want to go?

BACKGROUND AND OBJECTIVE: There is great heterogeneity in the methodology and evaluation in specialized health training (SHT) in otorhinolaryngology in our country. The figure of the resident tutor is the cornerstone on which the ESF system is based and the regulation and recognition of this figure varies. This article aims to take a snapshot of the current situation of the ESF in Spain and to describe the activity of tutors. MATERIALS AND METHODS: During the month of September 2023, a survey was sent in a Google Forms® format through the Spanish Society of Otolaryngology and Head and Neck Surgery. The survey consisted of 8 multiple-choice questions and 4 questions in which they were asked to rank a series of 5 weaknesses, threats, opportunities and strengths selected by the authors, in order to perform a SWOT analysis. RESULTS: A total of 103 responses were obtained, of which 81 corresponded to accredited tutors. 63% of the tutors indicated that they did not have enough time to carry out their teaching work and 48% did not carry out a regular assessment of their residents. 64% of the tutors believe that the quality of otorhinolaryngology training in Spain is good and 61% are satisfied with their job as tutors. The main weakness was the short duration of the training programme, and the pressure of care was found to be the main threat. An experienced training system was considered the main strength and the creation of a national network of tutors was seen as an opportunity for improvement. CONCLUSIONS: The creation of a common and transversal otorhinolaryngology training pathway for all accredited centres and the creation of a network of mentors and residents are necessary to address the problems of SHT. The role of the tutor must be recognised and reinforced to improve specialist training.

Survivin/BIRC5 as a novel molecular effector at the crossroads of glucose metabolism and radioresistance in head and neck squamous cell carcinoma.

BACKGROUND: Metabolic reprogramming and abnormal glucose metabolism are hallmarks of head and neck squamous cell carcinoma (HNSCC). Certain oncogenes can promote cancer-related metabolic changes, but understanding their crosstalk in HNSCC biology and treatment is essential for identifying predictive biomarkers and developing target therapies. METHODS: We assessed the value of survivin/BIRC5 as a radioresistance factor potentially modulated by glucose for predicting therapeutic sensitivity and prognosis of HNSCC in a cohort of 32 patients. Additionally, we conducted in vitro experiments to explore the role of survivin/BIRC5 in glucose metabolism concerning radiation response. RESULTS: Tumoral BIRC5 expression is associated with serum glucose and predicts locoregional disease-free survival and lower BIRC5 mRNA levels are associated with better outcomes. Upregulation of BIRC5 by radiation depends on glucose levels and provokes a pro-tumoral and radioresistant phenotype in surviving cells. CONCLUSIONS: Survivin/BIRC5 might be independently associated with the risk of recurrence in patients with HNSCC.

Relationship between transcriptional expression of pyruvate dehydrogenase and local control of disease in patients with oral cavity carcinomas / Relación entre la expresión transcripcional de piruvato deshidrogenasa y el control local de la enfermedad en pacientes con cáncer en la cavidad oral

Background The altered cellular metabolism is one of the hallmarks of the cancer cells, favoring the process of aerobic glycolysis, known as the Warburg effect. The pyruvate dehydrogenase (PDH) complex is one of the elements involved in this metabolic process. The present study aims to evaluate the relationship between the transcriptional expression of PDHB and the risk of local recurrence in patients with oral cavity carcinomas. Methods We determined the transcriptional expression of PDHB in biopsies from 41 patients with oral cavity carcinomas treated with surgery. The PDHB expression was categorized according to the local control of the disease with a recursive partitioning analysis. Results During the follow-up period 13 patients (31.7%) had a local recurrence of the tumor. Considering local disease control as the dependent variable, the recursive partitioning analysis classified the patients in two categories according to high (n=16, 39.0%) or low (n=25, 61.0%) PDHB expression. Five-year local recurrence-free survival for patients with high PDHB expression was 84.8% (95% CI: 65.2-100%), and for patients with low expression it was 54.3% (95% CI: 34.3–74.2 %) (P=0.034). The results of multivariate analysis showed that patients with a low PDHB expression had a 4.90 times higher risk of local recurrence of the tumor (95% CI: 1.02–22.68, P=0.042). Conclusion There is a relationship between the metabolic characteristics of the tumor and its aggressiveness. According to our results, patients with oral cavity carcinomas with low transcriptional expression levels of PDHB have a significantly higher risk of local tumor recurrence. (AU)

Antecedentes La alteración del metabolismo celular es una de las características distintivas de las células cancerígenas, y favorece el proceso de la glucólisis aeróbica, conocido como efecto de Warburg. El complejo de piruvato deshidrogenasa (PDH) es uno de los elementos implicados en este proceso metabólico. El objetivo del presente estudio es evaluar la relación entre la expresión transcripcional de PDHB y el riesgo de recidiva local en los pacientes con cáncer en la cavidad oral. Métodos Determinamos la expresión transcripcional de PDHB en biopsias de 41 pacientes con cáncer en la cavidad oral tratados con cirugía. Se categorizó la expresión de PDHB de acuerdo con el control local de la enfermedad, con un análisis de partición recursiva. Resultados Durante el periodo de seguimiento, trece pacientes (31,7%) tuvieron una recidiva local del tumor. Considerando el control de la enfermedad local como variable dependiente, el análisis de partición recursiva clasificó a los pacientes en dos categorías, de acuerdo con la expresión de PDHB alta (n=16, 39%) o baja (n=25, 61%). La tasa de supervivencia libre de enfermedad a cinco años con expresión alta de PDHB fue del 84,8% (95% IC: 65,2–100%), siendo del 54,3% (95% IC: 34,3–74,2%) (P=0,034) para los pacientes con expresión baja. Los resultados del análisis multivariante reflejaron que los pacientes con expresión baja de PDHB tuvieron un riesgo 4,90 veces mayor de recidiva local del tumor (95% IC: 1,02–22,68, P=0,042). Conclusión Existe una relación entre las características metabólicas del tumor y su agresividad. Conforme a nuestros resultados, los pacientes con cáncer en la cavidad oral y bajos niveles transcripcionales de PDHB tienen un riesgo significativamente mayor de recidiva local del tumor. (AU)

Objetivo: Analizar la relación entre la expresión transcripcional de interleucina-8 (IL-8) y la respuesta al tratamiento con radioterapia o quimio-radioterapia en pacientes con carcinoma escamoso de cabeza y cuello (CECC).Material y métodosEstudio retrospectivo realizado a partir de biopsias de tumor obtenidas de forma previa a un tratamiento con radioterapia o quimio-radioterapia en 87 pacientes con CECC. Se dispuso de una muestra de mucosa sana en 35 ocasiones. Se determinó la expresión transcripcional de la IL-8 mediante RT-PCR. Se categorizó el nivel de expresión transcripcional de IL-8 en función del control local de la enfermedad mediante un análisis de partición recursiva.ResultadosLa expresión transcripcional de IL-8 en el tejido tumoral fue unas 50 veces superior al de las muestras de mucosa sana. La supervivencia libre de recidiva local a los 5años para los pacientes con una expresión transcripcional elevada de IL-8 (n=56) fue del 65,6%, y para los pacientes con una expresión baja (n=31) del 90,2% (p=0,017). De acuerdo con los resultados de un análisis multivariante, los pacientes con unos niveles de expresión elevada de IL-8 contaron con un riesgo 4,1 veces superior de recidiva local de la enfermedad.ConclusionesLos CECC cuentan con un incremento significativo en los niveles de expresión transcripcional de la IL-8 en relación con el tejido no tumoral. Los tumores con unos niveles de expresión elevados de IL-8 tienen un incremento en el riesgo de sufrir una recidiva local del tumor tras un tratamiento con radioterapia o quimio-radioterapia. (AU)

Objective: To analyse the relationship between the transcriptional expression of interleukin-8 (IL-8) and response to treatment with radiotherapy or chemo-radiotherapy in patients with squamous cell carcinoma of the head and neck (SCCHN).Material and methodsRetrospective study from tumour biopsies obtained before a treatment with radiotherapy or chemo-radiotherapy in 87 patients with SCCHN. We had a sample of healthy mucosa in 35 cases. We determined the transcriptional expression of IL-8 with RT-PCR. The transcriptional expression of IL-8 was categorized according to the local control of the disease with a recursive partitioning analysis.ResultsThe transcriptional expression of IL-8 in tumour tissue was about 50 times higher than that in the samples of healthy mucosa. Patients with a high transcriptional expression of IL-8 (n=56) had a 5-year local recurrence-free survival of 65.6%, and for patients with low expression (n=31) it was 90.2% (P=.017). According to the results of a multivariate analysis, patients with high expression of IL-8 had a 4.1 higher risk of local recurrence of the tumour.ConclusionsSCCHN have a significant increase in transcriptional expression of IL-8 in relation to non-tumour tissue. Tumours with high IL-8 expression have an increased risk of local recurrence after treatment with radiotherapy or chemo-radiotherapy. (AU)

Importancia del diagnóstico diferencial en rinología: hamartoma respiratorio adenoepitelial / The importance of the differential diagnosis in rhinology: respiratory epithelial adenomatoid hamartoma of the sinonasal tract

Introducción: El Hamartoma respiratorio adenoepitelial (HRA) es una lesión poco común de la nariz y los senos paranasales caracterizada por la formación anormal de tejido glandular. Fue descrita por primera vez por Wenig y cols., en 1995 y, desde entonces, tan sólo se ha publicado unos 60 casos. Material y métodos: En este trabajo, presentamos el estudio de seis casos de hamartoma de cavidad nasal, los cuales fueron diagnosticados y tratados en nuestro Centro entre los años 2005 y 2010. Asimismo, realizamos un estudio completo del diagnóstico diferencial de esta patología, tanto a nivel clínico como anatomopatológico. Resultados: En estos pacientes, la razón hombre: mujer fue 5:1, con una media de edad de 63,1 años (DE=16,9). Todos los sujetos presentaron afectación de la fosa nasal y, en tres casos, ocupación de los senos maxilar, frontal y etmoidal. Los síntomas más frecuentes fueron obstrucción nasal, rinorrea y pérdida de olfato. Todos los casos fueron tratados mediante cirugia endoscópica nasosinusal sin evidencia de recirrencia en el periodo de seguimimento (28,2 meses, DE=11,5). Las características más importantes del HRA son: edema estromal, proliferación glandular seromucosa, proliferación fibroblástica y vascular, infiltrado inflamatorio mixto, incremento de la proliferación adenomatoide, acúmulo de material glandular y cambios atróficos del epitelio. Conclusión: Sugerimos que el diagnóstico diferencial debe realizarse con la poliposis nasosinusal, pólipo antrocoanal, papiloma invertido y adenocarcinoma. Un diagnóstico incorrecto podría dar lugar a un tratamiento demasiado agresivo. Esta revisión de los casos publicados, con énfasis en el diagnóstico diferencial es de interés tanto para otorrinolarigólogos como anatomopatólogos (AU)

Introduction: Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon lesion of the nasal and paranasal sinuses. It was first described in 1995 by Wenig and Heffner, and only about 60 cases have been published since then. Material and methods: We present 6 case studies of nasal cavity hamartoma diagnosed and treated at our institution between 2005 and 2010. We also conducted a literature review and comprehensive study of the differential diagnosis of this condition, both clinical and pathological. Results: The male-female ratio was 5:1, with a mean age of 63.1 years. The most frequent symptoms were nasal obstruction, rhinorrhea and loss of smell. All cases were treated with endoscopic sinus surgery, without recurrences in the follow-up period (28.2 months; SD=11.5 months). Conclusion: We suggest that differential diagnosis should be made on the basis of nasal polyps, antrochoanal polyps, inverted papilloma and low-grade adenocarcinoma. This review of published cases is of equal interest to both pathologists and otorhinolaryngologists (AU)
