Abstract

Objective: To determine the role of vitamin D deficiency as a risk factor for carcinoma breast. 

Study Setting: Khyber Teaching Hospital Peshawar in Khyber Pakhtunkhwa.

Study Duration: Minimum of 6 months after approval of synopsis.

Study Design: Case-control study 

Material and Methods: After taking approval from the hospital ethical committee, 256 patients were included in the study, between August 2022 and January 2023, divided equally into 2 groups as cases (breast cancer) and controls (breast diseases other than cancer). Vitamin D levels along with other variables were collected in Microsoft excel sheet and shifted to SPSS data base for analysis and the results shown in tables and charts.

Results: The mean age for cases was 47.8 ± 11.6 SD and for controls was 33.7 ± 12.7 SD. The mean BMI for cases was 27.9 kg/m2 ± 3.3 and for controls was 26.6 kg/m2 ± 3.4. Other biological variables did not show much variation between both groups. The adjusted OR for cases showed significant association between low vitamin D levels {OR 1.25 with 95% CI (0.74-2.12), p value 0.01} and higher BMIs {OR 1.63 with 95% CI (0.96-2.75), p-value 0.05} with increased risk of breast cancer. Adjustment for age, sun exposure and use of vitamin D supplements did not show any significant association with risk of developing breast cancer.

Conclusion: Since Vitamin D was found deficient in most of our study subjects, it can be considered as an independent risk factor in progression of breast cancer disease.
