RESUMO

Introducción y objetivos: A lo largo de las últimas décadas han aparecido una serie cambios con capacidad de modificar las características epidemiológicas de los pacientes con carcinomas escamosos de cabeza y cuello (CECC), como el incremento en las expectativas de vida, la modificación en los patrones de consumo de tabaco y alcohol, o la infección por virus del papiloma humano (HPV). El objetivo del presente estudio es analizar la existencia de modificaciones en las características epidemiológicas y clínicas de este tipo de pacientes a lo largo de un periodo de 30 años. Métodos: Estudio retrospectivo de 5.123 pacientes con CECC tratados durante el periodo 1985-2017. Se evaluó la existencia de modificaciones en los patrones de edad, sexo, consumo de tóxicos, y localización y extensión del tumor a lo largo del periodo de estudio. Para los pacientes con carcinomas de orofaringe se evaluó el estatus HPV. Resultados: A lo largo del periodo de estudio se incrementó de forma significativa el promedio de edad y el porcentaje de pacientes de sexo femenino, disminuyendo el porcentaje de pacientes con uso severo de tóxicos. A nivel del tumor, observamos una disminución en el porcentaje de pacientes con tumores de la laringe, incrementándose los pacientes con tumores iniciales cT1 y con afectación ganglionar cN2. Pudimos evidenciar un incremento progresivo en el porcentaje de pacientes con carcinomas de orofaringe HPV-positivos. Conclusiones: Durante las últimas décadas se han producido modificaciones significativas en las características epidemiológicas y clínicas de los pacientes con CECC


Introduction and objectives: The epidemiological characteristics of patients with head and neck cancer squamous cell carcinoma (HNSCC) have changed over recent years. The increase in life expectancy of the population, changed patterns of tobacco and alcohol use, and human papillomavirus infection (HPV) have brought about significant changes. The objective of the present study is to analyze the changes in the epidemiological and clinical characteristics of these patients over a 30-year period. Methods: Retrospective study of 5,123 patients with HNSCC treated over the period 1985-2017. We evaluated the existence of changes in the patterns of age, sex, tobacco and alcohol use, and location and extension of the tumours throughout the study period. HPV status was evaluated for patients with oropharyngeal carcinomas. Results: Throughout the study period there was a significant increase in the mean age at presentation and in the percentage of women, and a decrease in the percentage of patients with history of high consumption of toxic substances. We observed a decrease in the proportion of patients with laryngeal cancer, and an increase of patients with early tumours cT1 and with neck disease cN2. We detected a progressive increase in the proportion of HPV-positive oropharyngeal carcinoma patients. Conclusion: Over recent decades there have been significant changes in the epidemiological and clinical characteristics of patients with HNSCC

RESUMO

Background: The present study attempted to provide information regarding non-muscle myosin II (MII) isoforms immunoreactivity in patients with head and neck squamous cell carcinoma (HNSCC) and analysis of the patients' clinical status after 5 years of monitoring. Material and Methods: A semiquantitative analysis of the immunoreactivity of the MII isoforms was performed in 54 surgical specimens and its correlation with clinical and pathological variables and prognosis was verified. Data were analyzed using chi-square, Mann-Whitney and Kruskal-Wallis tests. To evaluate the survival over the total monitoring time and any connection with the proteins studied, the Kaplan-Meier analysis was used. P values ≤0.05 were considered statistically significant. Results: In the advanced stages of pathological tumor-node-metastasis, the expression of MIIB in adjacent non-neoplastic epithelial tissues tended to increase (p = 0.057). In tumoral zones there was an association of high expression among the three isoforms (MIIA/MIIB p = 0,001, MIIB/MIIC p = 0,006 and MIIA/MIIC p = 0,012). Negative clinical evolution in patients was directly correlated to increased MIIC expression in the tumoral zone of invasion in HNSCC (p = 0.017). Based on clinical evolution after the monitoring period, patients with tumors expressing MIIC had poorer prognoses (p = 0.048). Conclusions: The present study suggests that MIIB expression in non-neoplastic adjacent epithelial tissues may indicate a potential for regional metastasis and that MIIC expression in the tumoral zone of invasion is predictive of negative evolution of the disease
