SEOM clinical guidelines for the treatment of head and neck cancer (2017)

Head and neck cancer (HNC) is defined as malignant tumours located in the upper aerodigestive tract and represents 5% of oncologic cases in adults in Spain. More than 90% of these tumours have squamous histology. In an effort to incorporate evidence obtained since 2013 publication, Spanish Society of Medical Oncology (SEOM) presents an update of HNC diagnosis and treatment guideline. The eighth edition of TNM classification, published in January 2017, introduces important changes for p16-positive oropharyngeal tumours, for lip and oral cavity cancer and for N3 category. In addition, there are new data about induction chemotherapy and the role of immunotherapy in HNC (AU)

Epidemiological characteristics of a Spanish cohort of patients diagnosed with squamous cell carcinoma of head and neck: distribution of risk factors by tumor location

Purpose. Head and neck cancer is a highly heterogeneous disease comprising a large number of tumors located in the cervicofacial area. This study aimed to determine the epidemiological characteristics of squamous-cell carcinomas of the head and neck in the Spanish population, and the distribution of risk factors based on tumor locations. Methods/patients. A cohort of 459 patients (75 oral cavity, 167 oro-/hypopharyngeal and 217 laryngeal cancers) recruited in 19 hospitals participating in the Spanish head and neck cancer cooperative group were included over 3 years (2012-2014). Epidemiological parameters and risk factors were obtained from a self-administered questionnaire, and tumor characteristics were obtained from clinical records. Multivariate multinomial logistic regression was used to assess factors associated with tumor location. Results. Most patients were males (88.4 %), smokers (95 %) and drinkers (76.5 %). Relative to laryngeal cancer, pharyngeal cancer and oral cancer were more common in women than men (OR 3.58, p = 0.003 and 4.33, p = 0.001, respectively); pharyngeal cancer was more associated with rural environment (OR 1.81, p = 0.007) and weekly alcohol intake (10-140 g: OR 2.53, p = 0.012; 141-280 g: OR 2.47, p = 0.023; >280 g: OR 3.20, p = 0.001) and less associated with pack-years of smoking (21-40 packs: OR 0.46, p = 0.045; 41-70 packs: OR 0.43, p = 0.023; ≥71 packs: OR 3.20, p = 0.015). Conclusions. The distribution of these tumors differs between the sexes, with a higher proportion of oral cavity and pharyngeal tumors in women than in men. Oro-/hypopharyngeal cancers were more strongly associated with rural areas and with alcohol consumption, although less strongly associated with smoking than laryngeal tumors (AU)

SEOM clinical guidelines for the treatment of head and neck cancer

Head and neck cancer constitutes the fifth highest cause of cancer in Spain. It is a neoplasm with a high possibility of cure if it is diagnosed in early stages, but unfortunately two thirds of the patients are diagnosed at an advanced loco-regional stage (stage III and IV, without metastasis). The multidisciplinary team, bringing together all professionals who specialize in the diagnosis and treatment of these tumors make the decision to establish the best sequence of individualized diagnosis, staging and treatment for each patient. This guide gives recommendations for diagnosis, staging and treatment for squamous cell carcinoma of the head and neck. In order to simplify the amount of information about any subsite of the head and neck area, the treatment recommendations are summarized as local disease, locally advance resectable and unresectable stages, function-preserving laryngeal treatment and recurrent and metastatic disease (AU)

SEOM clinical guidelines for the treatment of nasopharyngeal carcinoma

Nasopharyngeal carcinoma is an unusual tumour in Spain. It has differences in epidemiology, histology, clinical behaviour, treatment and prognosis from those of other head and neck neoplasms, which justifies separate analysis. It is a neoplasm with a high possibility of cure with a combined treatment if even it is diagnosed in an advanced locoregional stage (stage III or IV, without metastasis). The multidisciplinary team, bringing together all professionals who specialize in the diagnosis and treatment of these tumors make the decision to establish the best sequence of individualized diagnosis, staging and treatment for each patient. This guide gives recommendations for diagnosis, staging and treatment for nasopharyngeal carcinoma. The treatment recommendations are summarized as local disease, locally advance and recurrent and metastatic disease (AU)

Resultados asistenciales de un único centro en el tratamiento del carcinoma indiferenciado de nasofaringe / Medical assistance results at a single center in the treatment of undifferentialed nasopharyngeal carcinoma

Objetivo: Revisión retrospectiva de nuestra experiencia en el tratamiento del carcinoma de nasofaringe. Material y método: Analizamos 38 pacientes (26 hombres, 12 mujeres). Realizamos análisis de supervivencia mediante el método de Kaplan y Meier. Resultados: La mediana de edad de la serie fue de 44 años (15-78). El 93 por ciento de los pacientes presentaban estadios avanzados al diagnóstico. El tratamiento fue: radioterapia 12 pacientes (32 por ciento), radioterapia y quimioterapia 24 casos (63 por ciento), radioterapia y cirugía 1 paciente (3 por ciento) y cirugía 1 caso (3 por ciento). Tasa de respuesta fue de 87 por ciento (82 por ciento RC, 5 por ciento RP). La tasa de recaída fue del 50 por ciento. La mediana del tiempo hasta la progresión fue de 16.6 meses y la de supervivencia de 54 meses con una supervivencia proyectada a 10 años del 38 por ciento. Conclusiones: El carcinoma de nasofaringe es un tumor diferente al resto de tumores de cabeza y cuello. La radioterapia ha sido clásicamente el tratamiento estándar. Actualmente en tumores no metastáticos la combinación de quimioterapia y radioterapia debe ser el tratamiento estándar. El papel de la quimioterapia como tratamiento adyuvante está por definir. (AU)
