Aim:
There are inconsistent results about the effects of vitamin D level on breast cancer prognosis. We aimed to investigate the effect of vitamin D levels on the prognosis of resectable breast cancer in a patient group with highly different clothing styles.
Patients & Methods:
A total of 186 breast cancer patients were enrolled in the study.
Results:
Vitamin D level was sufficient, insufficient and deficient in 17.2, 52.2 and 30.6% of patients, respectively. There was a significant relationship between clothing style and serum 25 (OH) D levels. We could not establish any relation between vitamin D level and tumor characteristics or survival.
Conclusion:
Vitamin D supplementation can be more important than diagnostic serum vitamin D level on prognosis of breast cancer.

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...
