Exercise and cancer: a position statement from the Spanish Society of Medical Oncology.

Due to improvements in the number of cancer survivors and survival time, there is a growing interest in healthy behaviors, such as physical activity (PA), and their potential impact on cancer- and non-cancer-related morbidity in individuals with cancer. Commissioned by the Spanish Society of Medical Oncology (SEOM), in this review, we sought to distill the most recent evidence on this topic, focusing on the mechanisms that underpin the effects of PA on cancer, the role of PA in cancer prevention and in the prognosis of cancer and practical recommendations for clinicians regarding PA counseling. Despite the available information, the introduction of exercise programs into the global management of cancer patients remains a challenge with several areas of uncertainty. Among others, the most effective behavioral interventions to achieve long-term changes in a patient's lifestyle and the optimal intensity and duration of PA should be defined with more precision in future studies.

Cáncer de mama y ejercicio físico: estudio piloto / Breast cancer and physical exercise: pilot study

Objetivo. El cáncer de mama (CM) es el más común entre las mujeres occidentales, con un alto porcentaje de supervivencia, la cual no está exenta de numerosos efectos secundarios tanto por los tratamientos como por la enfermedad, afectando a la calidad de vida de estas mujeres. El objetivo de este proyecto es conocer el efecto de un programa de ejercicio físico conducido en la calidad de vida de mujeres afectadas por cáncer de mama. Método. El programa de ejercicio físico consistió en 24 sesiones (doce semanas) y se desarrolló íntegramente en la Facultad de Ciencias de la Actividad Física y del Deporte-INEF (UPM), donde se estudió a 31 mujeres afectadas. Resultados. Se muestra una mejora en la calidad de vida (p= 0,034), así como en diferentes aspectos de autoestima y depresión (p = 0,029 y p = 0,003 para el primero y p = 0,018 y p = 0,015 para el segundo). También se observó una mejora en el índice de fuerza general (p = 0,009) y en la capacidad funcional (p = 0,005). Conclusiones. Estos resultados permiten asociar un programa de ejercicio físico regular con posibles mejoras en la calidad de vida de las mujeres afectadas por cáncer de mama(AU)

Objective. Breast cancer is the most common cancer in occidental women. It presents a very high survival with a lot of side effect produced by the treatments, what affect to these women quality of life. Our goal is to know the effect of a guide exercise program on quality of life of breast cancer women. Methods. This program consisted in 24 classes and it was developed in the faculty of Physical Activity and Sport Science (UPM). 31 women were studied. Results. They showed an increase in their quality of life (p = 0.034), and in different psychological aspects as depression (p = 0.029 y p = 0.003) and self-esteem (p = 0.018 y p = 0.015). Also a positive change was observed in the global strength (p = 0.009) and in the functional capacity (p = 0.005). Conclusion. These results suggest that could exist an association between regular exercise programs with improvements in quality of life in women with breast cancer(AU)
