A healthy level of vitamin D can boost breast cancer outcomes

THURSDAY, JUNE 10, 2021 (HealthDay News) – Patients with adequate levels of breast cancer patients Vitamin D. “Vitamins of the Sun” – have better long-term results at the time of diagnosis, a new study has found.

Combined with the results of previous research, the new findings “bring continued benefits to patients who maintain a sufficient level [of vitamin D] through and beyond treatment of breast cancersaid Song Yao, author of the study. He is a professor of oncology in the Department of Cancer Prevention and Control at the Roswell Park Comprehensive Cancer Center, Buffalon, NY.

The study also found that black women had the lowest levels of vitamin D, which may have helped after explaining the worse results. diagnosis of breast cancer, Said Yao’s team.

The findings were presented at the last year’s virtual meeting of the American Clinical Oncology Association.

An oncologist unrelated to the research said the findings could offer women a new and easier way to fight breast cancer.


Vitamin D “can be found in some foods and is made by sunlight when it hits a human skin,” explains Dr. Alice Police, a breast cancer researcher at Northwell Health’s Northwell Health Institute for Women’s Health, in Westchester, NY

“This may be an important intervention in breast cancer outcomes for all women, but especially in the black population,” she said.

The study included nearly 4,000 patients who had their vitamin D levels checked and had a median follow-up of almost 10 years.

Patients were divided into three levels: vitamin D deficiency (less than 20 nanograms per blood test per milliliter); sufficient (20 to 29 ng / ml); or sufficient (30 ng / ml or more).

The study was not designed to prove cause and effect. However, she found – compared to low-nutrient women – women with adequate vitamin D levels had a 27% lower chance of dying from 27% of the causes at 10-year follow-up, and a 22% lower chance of dying from breast cancer. exactly.

The group also found that the link between vitamin D levels and breast cancer outcomes was similar regardless of the status of the estrogen receptor (ER) in the tumor. The association was somewhat stronger among those who weighed less and were diagnosed with more advanced breast cancer.


“The findings of this large cohort of long-term breast cancer survival survivors and observers provide the strongest evidence to date to maintain sufficient vitamin levels among breast cancer patients, especially black women and patients with more advanced disease,” Yao said in a note from Roswell Park .

Dr. Paul Baron is the head of breast surgery and director of the Breast Cancer Program at Lenox Hill Hospital in New York City. He was not involved in the new study, but said it was “an important study” because it shows the importance of having enough vitamin D levels to improve the long-term survival of patients with obvious cancer.

For its part, police said the findings underscore the importance of women with adequate vitamin D.

The difference in outcomes among patients with black-and-white breast cancer “was reduced with higher levels of vitamin D at the time of diagnosis,” he noted. “It can be an important step in efforts to level the field of this disease: let the sun in!”


Since these findings were presented at a medical meeting, they should be considered preliminary until they are published in a peer-reviewed journal.
