Differential characteristics of patients with squamous cell carcinoma of the head and neck with no history of tobacco or alcohol use.

OBJECTIVE: The present study aims to analyse the differential characteristics of patients with head and neck squamous cell carcinoma (HNSCC) without a history of consumption of toxic substances such as tobacco and alcohol. MATERIAL AND METHODS: We carried out a retrospective study of 4694 patients with HNSCC located in the oral cavity, oropharynx, hypopharynx or larynx treated in our centre during the period 1985-2019. RESULT: 7.7% of the patients (n = 363) did not report a history of consumption of toxic substances. The group of patients with no toxic history was older, had a higher proportion of women, a higher frequency of cases located in the oral cavity, a higher proportion of cases diagnosed in early stages, and a lower incidence of second neoplasms. The percentage of patients with no history of consumption of toxic substances increased significantly over the study period. The overall survival of patients with no history of consumption of toxic substances was significantly higher than that of patients with toxic substances use. Specific survival for patients with tumours located in the oral cavity without a history of consumption of toxic substances was significantly lower than that of patients with toxic substances use, whereas for patients with oropharyngeal carcinomas the absence of a history of consumption of toxic substances was associated with a better prognosis. CONCLUSIONS: There were differences in the epidemiological and prognostic characteristics of patients with HNSCC according to the history of consumption of toxic substances such as tobacco and alcohol.

Características diferenciales de los pacientes con carcinoma escamoso de cabeza y cuello sin antecedentes de consumo de tabaco ni alcohol / Differential characteristics of patients with squamous cell carcinoma of the head and neck with no history of tobacco or alcohol use

Objetivo: El objetivo del presente estudio es analizar las características diferenciales de los pacientes con un carcinoma escamoso de cabeza y cuello (CECC) sin antecedentes de consumo de tóxicos, como el tabaco y el alcohol.Material y métodosSe llevó a cabo un estudio retrospectivo de 4.694 pacientes con un CECC localizado en la cavidad oral, orofaringe, hipofaringe o laringe tratados en nuestro centro durante el periodo 1985-2019.ResultadoUn 7,7% de los pacientes (n=363) no refirieron el antecedente de consumo de tóxicos. El grupo de pacientes sin antecedentes tóxicos tenía mayor edad, una mayor proporción de mujeres, una mayor frecuencia de casos localizados en la cavidad oral, una mayor proporción de casos diagnosticados en estadios iniciales y una menor incidencia de segundas neoplasias. El porcentaje de pacientes sin antecedentes de consumo de tóxicos aumentó de forma significativa a lo largo del periodo de estudio. La supervivencia global de los pacientes sin antecedentes de consumo de tóxicos fue significativamente más elevada que la de los pacientes con antecedentes tóxicos. La supervivencia específica para los pacientes con tumores localizados en la cavidad oral sin antecedentes tóxicos fue significativamente inferior, en tanto que para los pacientes con carcinomas de orofaringe la ausencia de antecedentes de consumo de tóxicos se asoció a un mejor pronóstico.ConclusionesExistieron diferencias en las características epidemiológicas y pronósticas de los pacientes con CECC en función del antecedente de consumo de tóxicos como el tabaco o el alcohol.

Head and neck squamous cell carcinoma in cigar smokers. Distinctive epidemiological and prognostic characteristics.

OBJECTIVE: The objective of this study is to assess the existence of differences in the epidemiological characteristics and prognosis of patients with head and neck squamous cell carcinoma (HNSCC) who smoke cigars. MATERIAL AND METHODS: We carried out a retrospective study of a cohort of 4500 patients with HNSCC treated during the period 1985-2017. RESULT: The proportion of cigar smokers was 2.4%, compared with 88.3% of cigarette smokers and 9.3% of non-smokers. There was an increase in the proportion of cigar smokers throughout the study period. With respect to cigarette smokers, cigar smokers had a higher proportion of male patients, a higher average age at diagnosis, and they had a higher frequency of tumours located in the oral cavity and hypopharynx. The results of a univariate analysis showed that the disease-specific survival of cigar smokers was lower than that of the other patients. Five-year disease-specific survival of cigar smokers was 60.9%, compared to 69.0% for non-smokers, 72.8% for smokers of less than 20 cigarettes/day, and 67.2% for smokers of more than 20 cigarettes/day. There were differences in the pattern of survival depending on tobacco consumption based on the location of the primary tumour. CONCLUSIONS: A 2.4% of patients with HNSCC had a history of regular consumption of cigars. Disease-specific survival of cigar smokers was lower than that of other patients.

Pacientes fumadores de cigarros con carcinomas escamosos de cabeza y cuello. Características epidemiológicas y pronósticas diferenciales / Head and neck squamous cell carcinoma in cigar smokers. Distinctive epidemiological and prognostic characteristics

Objetivo: El objetivo del presente estudio es evaluar la existencia de diferencias en las características epidemiológicas y el pronóstico de los pacientes fumadores de cigarros con carcinomas escamosos de cabeza y cuello (CECC).Material y métodosEstudio retrospectivo de una cohorte de 4.500 pacientes con CECC tratados durante el periodo 1985-2017.ResultadoLa proporción de fumadores de cigarros fue del 2,4%, frente a un 88,3% de fumadores de cigarrillos y 9,3% de no fumadores. Se observó un incremento en la proporción de fumadores de cigarros a lo largo del periodo de estudio. En relación con los fumadores de cigarrillos, los fumadores de cigarros contaron con una mayor proporción de pacientes varones, una edad media de diagnóstico más avanzada, y una mayor frecuencia de tumores localizados en cavidad oral e hipofaringe. El resultado de un estudio univariante mostró que la supervivencia específica de los fumadores de cigarros fue inferior a la del resto de pacientes. La supervivencia específica a los cinco años fue del 60.9% para los fumadores de cigarros, del 69,0% para los no fumadores, del 72,8% para los fumadores de menos de 20 cigarrillos/día, y del 67,2% para los fumadores de más de 20 cigarrillos/día. Existieron diferencias en el patrón de supervivencia, dependiendo del consumo de tabaco en función de la localización del tumor primario.ConclusionesUn 2,4% de los pacientes con CECC contaron como antecedente el consumo habitual de cigarros. La supervivencia específica de los pacientes fumadores de cigarros fue inferior a la del resto de pacientes. (AU)

Resultados oncológicos del tratamiento de rescate en pacientes con carcinomas de hipofaringe / Oncological results of salvage treatment in patients with hypopharyngeal carcinoma

INTRODUCCIÓN Y OBJETIVOS: El objetivo del presente estudio es analizar las variables relacionadas con la posibilidad de llevar a cabo una cirugía de rescate con intención radical en pacientes con carcinomas de hipofaringe con una recidiva local del tumor, así como evaluar el rendimiento oncológico de este tipo de cirugías. MÉTODOS: Estudio retrospectivo de 96 pacientes con carcinoma de hipofaringe con una recidiva local del tumor. RESULTADOS: Sólo 27 pacientes (28,1%) fueron considerados candidatos a cirugía de rescate. Las variables relacionadas con que el paciente fuese tratado con una cirugía de rescate fueron el tratamiento no quirúrgico inicial y un intervalo libre de enfermedad superior a los seis meses. Los 69 pacientes no candidatos a tratamiento quirúrgico de rescate fallecieron como consecuencia de la evolución del tumor en un periodo inferior a los 2,5 años. La supervivencia específica a los cinco años para los pacientes tratados con una cirugía de rescate fue del 39,5%. La única variable que se relacionó de forma significativa con la supervivencia específica fue el estatus de los márgenes de resección. Los pacientes con una recidiva tumoral extensa (rT3-4) o con una afectación ganglionar simultánea tuvieron una peor supervivencia, pero sin que las diferencias alcanzasen la significación estadística. CONCLUSIÓN: Sólo un 28,1% de los pacientes con carcinomas de hipofaringe con una recidiva local del tumor fueron considerados candidatos a tratamiento de rescate quirúrgico con intención radical. De los pacientes tratados con una cirugía de rescate, la supervivencia específica a los cinco años fue del 39,5%

INTRODUCTION AND OBJECTIVE: The aim of this study is to analyse the variables related to the feasibility of salvage surgery with radical intention in patients with a local recurrence of hypopharyngeal carcinoma, and to evaluate the oncological performance of this type of surgery. METHODS: Retrospective study of 96 patients with hypopharyngeal carcinoma with local tumour recurrence RESULT: Only 27 patients (28.1%) were considered for surgical salvage treatment. The variables related to feasibility of salvage surgery were non-surgical initial treatment of the tumour and a disease-free interval greater than 6 months. All 69 patients non-candidates for salvage surgery died as a result of tumour progression in a period of less than 2.5 years. The 5-year disease-specific survival rate for the patients treated with salvage surgery was 39.5%. The only variable significantly related to disease-specific survival was the status of the resection margins. Patients with extensive tumour recurrence (rT3-T4) or with simultaneous nodal involvement had a lower survival rate, but the differences did not reach statistical significance. CONCLUSION: Only 28% of the patients with hypopharyngeal carcinoma with local recurrence of the tumour were eligible for salvage surgery with radical intention. The patients treated with salvage surgery had a 5 -year disease-specific survival of 39.5%
