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)

Experiencia del Hospital Universitario de Salamanca en el tratamiento sistémico adyuvante del cáncer de mama locorregional. Resultados de un protocolo asistencial tras 7 años de seguimiento / Salamanca University Hospital experience in the adjuvant systemic treatment of loco-regional breast cancer. Results of a medical assistance protocol of a seven-year follow-up

- Objetivos: evaluar la eficacia en términos de supervivencia libre de enfermedad (SLE) y supervivencia global (SG) y toxicidad de un protocolo asistencial para el tratamiento sistémico adyuvante del cáncer de mama.- Material y métodos: estudio prospectivo con 308 pacientes. Se diseñó un esquema de tratamiento escalonado en relación a grupos de riesgo, factores pronósticos asociados y factores biológicos. Las pacientes recibieron 4 esquemas de tratamiento diferentes (Tamoxifeno y/o quimioterapia sin antraciclinas o uno de los dos esquemas con antraciclinas con diferente intensidad de dosis).- Resultados: mediana de seguimiento: 7 años. La SLE y SG (ñ E.E.) fue: pacientes con ganglios negativos: 86 por ciento (ñ2 por ciento) y 91 por ciento (ñ2 por ciento) respectivamente; pacientes con ganglios positivos: 64 por ciento (ñ3) y 82 por ciento (ñ3). La SLE y la SG de todo el grupo fue del 75 por ciento (ñ2) y del 87 por ciento (ñ1) respectivamente. La principal toxicidad encontrada fue la hematológica en las pacientes tratadas con quimioterapia.- Conclusiones: El protocolo diseñado se ajusta a cada una de las pacientes en relación a los principales grupos de riesgo y factores pronósticos, de manera que se consigue optimizar la utilización y la selección de los diferentes agentes, tipos de quimioterapia e intensidad de dosis, evitando toxicidades innecesarias y alcanzando altos índices de eficacia en términos de SLE (AU)
