Nutritional Factors during and after Cancer: Impacts on Survival and Quality of Life.

The French National Cancer Institute conducted a collective expertise study with researchers and clinical experts from the French Network for Nutrition And Cancer Research (NACRe Network). The objective was to update the state of knowledge on the impacts of nutritional factors on clinical endpoints during or after cancer. Data from 150 meta-analyses, pooled analyses or intervention trials and 93 cohort studies were examined; they concerned 8 nutritional factors, 6 clinical events and 20 cancer locations.

"During and after cancer: identification of high-risk nutritional situations At the end of 2020, the French National Cancer Institute published a report presenting the state of knowledge on the impact of nutritional factors on clinical endpoints during or after cancer. This report is the result of a collective expertise by an expert group from the French Network for Nutrition And Cancer Research (NACRe Network, www.inrae.

[Impact of nutritional factors during and after cancer].

Nutritional factors (diet, weight, alcohol, physical activity) are identified as factors having an impact on the onset of several cancer sites. Less abundant scientific data also underline their impact on the tumor progression. A review of the scientific literature was carried out by a group of experts established by the French National Cancer Institute (INCa) to better document the influence of nutritional factors during and after cancer on outcomes such as overall mortality, cancer specific mortality, recurrence, second primary cancers and quality of life.

[Benefits of physical activity for cancer patients].

The prescription of physical activity for patients living with a long-term condition has been enshrined in legislation since 2016. The French National Cancer Institute published a literature review on the expected effects of physical activity in patients living with cancer. The benefits are prevention or correction of physical deconditioning, a preservation and/or a normalization of body composition, a reduction of cancerrelated fatigue, an overall quality-of-life improvement, the improvement of treatments tolerance and their medium and long-term effects, an increased life expectancy and a lower risk of cancer recurrence.

[Cancer prevention in France: Implication of health professionals].

Almost 40% of cancers are attributable to preventable cancer risk factors related to behavior. Health professionals must take into account the respective weight of the different causes of cancer to enforce effective cancer prevention. Their involvement is needed on several levels.

Alcoholic beverages, obesity, physical activity and other nutritional factors, and cancer risk: A review of the evidence.

Purpose: Prevention is a priority in the fight against cancers, especially nutritional prevention. To update the levels of evidence of relationships between 10 nutritional factors and cancer risk, the scientific literature published from 2006 to 2014 was reviewed by an expert group.

Methods: Data from 133 meta-analyses, pooled analyses or intervention trials were examined.
