Cervical cancerVitamin D levels

A study in Germany of cancer patients found “Seven patients with ovarian
carcinoma and 3 patients with cervix carcinoma were also examined. No less than 7 out of these 10 subjects displayed a plasma 25(OH)D concentration 1. This study also found that serum 25(OH)D level for those patients declined with age from a regression fit of 28 μg/l (ng/mL) at age 30 years to zero at 76 years. No separate information was given for cervical cancer.

A case-control study in Japan involving 405 incident cervical neoplasias (333 invasive carcinomas and 72 cervical intraepithelial neoplasias grade III [CIN3]) investigated the correlation of disease with respect to oral vitamin D and calcium intake2. For invasive cancer, there was a significantly reduced risk for > 291 international units (IU)/day vs 3.

On the other hand, there was no effect of vitamin D intake on CIN3 for nonsmokers, but there was a significantly reduced risk for smokers (P-trend = 0.02)2.For those taking 247 IU/day.
