| Popis: | Background: Recent data have shown an inverse association between serum 25-hydroxyvitamin D concentration and incidence of several cancers, including cutaneous malignant melanoma (CMM). In addition, lower serum 25-hydroxyvitamin D levels have been associated with thicker or higher stage melanomas and worse survival in observational studies. Materials and Methods: Ninety-nine patients diagnosed with primary CMM and 97 matched healthy controls entered the study. Demographic characteristics, risk factors for CMM, and clinical and histological characteristics were recorded for patients with primary CMM. Total serum 25-hydroxyvitamin D levels of melanoma patients measured by fully automated chemiluminescent vitamin D total immunoassay (Elecsys vitamin D total, Roche) at the time of diagnosis were compared with those of healthy controls. In addition, we tested the association of serum total 25-hydroxyvitamin D levels at melanoma diagnosis with known risk and prognostic factors for CMM. Results: Of the melanoma patients, 49 (49.49%) had deficient serum total 25-hydroxyvitamin D levels (30 ng/mL). The median serum total 25-hydroxyvitamin D levels were significantly lower in melanoma patients (20.62 ng/mL) compared with healthy controls (24.71 ng/mL), but statistical significance was not reached (chi-square test, P = 0.051) No statistically significant association was found between serum total 25-hydroxyvitamin D levels and demographic characteristics; risk factors for CMM; prognostic factors, such as Breslow thickness and ulceration; as well as clinical characteristics, such as melanoma stage, clinical type, and location. Conclusions: Lower serum 25-hydroxyvitamin D levels were found in our Greek cohort of melanoma patients compared with healthy controls, without reaching, however, statistical significance; these levels were not statistically associated with established risk and prognostic factors for CMM. |
