LOW “VITAMIN D” ASSOCIATED WITH DEATH IN BREAST CANCER
MAMMOGRAM (WHICH SIDE HAS IT?)

Dr. Pinna says:
This is another study, from Germany, with almost 1300 post menopausal women, indicating that low Vitamin D and a higher risk of death were associated.
We now know that Vitamin D is a hormone that regulates the immune system. A weak immune system allows cancers to grow.
All women should train themselves to take it daily. I recommend one thousand units daily, and a Vitamin D level every six months.
Introduction
Vitamin D has been postulated to be involved in cancer prognosis.
Thus far, only two studies reported on its association with recurrence and survival after breast cancer diagnosis yielding inconsistent results.
Therefore, the aim of our study was to assess the effect of post-diagnostic serum 25-hydroxyvitamin D [25(OH)D] concentrations on overall survival and distant disease-free survival.
Methods
We conducted a prospective cohort study in Germany including 1,295 incident postmenopausal breast cancer patients aged 50–74 years.
Patients were diagnosed between 2002 and 2005 and median follow-up was 5.8 years. Cox proportional hazards models were stratified by age at diagnosis and season of blood collection and adjusted for other prognostic factors. Fractional polynomials were used to assess the true dose-response relation for 25(OH)D.
Results
Lower concentrations of 25(OH)D were linearly associated with higher risk of death (hazard ratio (HR) = 1.08 per 10 nmol/L decrement; 95% confidence interval (CI), 1.00 to 1.17) and significantly higher risk of distant recurrence (HR = 1.14 per 10 nmol/L decrement; 95%CI, 1.05 to 1.24).
Compared with the highest tertile (≥ 55 nmol/L), patients within the lowest tertile (< 35 nmol/L) of 25(OH)D had a HR for overall survival of 1.55 (95%CI, 1.00 to 2.39) and a HR for distant disease-free survival of 2.09 (95%CI, 1.29 to 3.41). In addition, the association with overall survival was found to be statistically significant only for 25(OH)D levels of blood samples collected before start of chemotherapy but not for those of samples taken after start of chemotherapy (P for interaction = 0.06).
Conclusions
In conclusion, lower serum 25(OH)D concentrations may be associated with poorer overall survival and distant disease-free survival in postmenopausal breast cancer patients.
SIMPLE TRANSLATION: LOW VITAMIN D LEVELS WERE ASSOCIATED WITH POOR RESULTS.
