[Impact of nutrition on breast cancer mortality and risk of recurrence, a review of the evidence]. / Impact des régimes alimentaires sur la mortalité et le risque de récidive de cancer du sein : revue de la littérature.

INTRODUCTION: There is a growing interest in diets and their effects on cancer prognosis. In 2014, a report from the World Cancer Research Fund on diet and women with a history of breast cancer did not demonstrate a major effect on breast cancer prognosis. The aim of this literature review was to provide an update of knowledge in this area. METHODS: Randomized trials, prospective cohorts and meta-analyses published between 2012 and 2018 examining the impact of diet on recurrence risk and/or mortality after breast cancer were included, to achieve the objective. We evaluated study quality (according to Haute Autorité de Santé criteria) and the studied diets were categorized: macronutrients, micronutrients and selective foods. RESULTS: We selected eighteen articles that met levels of evidence 1 to 3. For macronutrients, a low-fat diet was associated with better survival. With regard to micronutrients, a diet rich in phytœstrogen reduced the risk of cancer recurrence. Finally, the adoption of a healthy diet was not associated with an improved prognosis for breast cancer but with an improvement in overall survival and risk of death from cardiovascular disease. DISCUSSION: This review suggests that nutrition influences the prognosis of breast cancer. Nevertheless, the level of evidence of the results was insufficient to make recommendations. Ultimately, a healthy and balanced diet could be encouraged in order to reduce global mortality.

Long-term outcomes of the Ahmed glaucoma valve surgery in childhood glaucoma.

PURPOSE: To report the rates of success of Ahmed glaucoma valve (AGV) surgery in early childhood glaucoma and factors associated with success. METHODS: Children with primary congenital or early childhood secondary glaucoma who underwent AGV surgery over a 10-year period (one eye per child) at a single institution were identified. Surgical failure was defined as having one or more of the following: intraocular pressure of >21 mm Hg 3 months postoperatively, reoperation for glaucoma, and vision loss to no light perception. RESULTS: A total of 178 patients were identified (median age, 5.8 ± 5.5 years): 125 with primary congenital and 53 with secondary childhood glaucoma. The success rate at 1 year was 92% (95% CI, 88%-96%); at 5 years, 64% (95% CI, 55%-73%); and at 10 years, 36% (95% CI, 25%-52%). Younger age at baseline (P = 0.003) and secondary childhood glaucoma (P = 0.045) were associated with lower success. CONCLUSIONS: The AGV is associated with high short-term success in children with primary congenital glaucoma, but the 10-year success rates are poor. Younger age and secondary childhood glaucoma may be associated with a more refractory outcome.
