Popis: 204 Background: In spite of the fact that cancer patients under palliative care represent the group of high risk for vitamin D deficiency (e.g. changed nutritional patterns and UV exposure), data reporting vitamin D levels in palliative care setting are rather scarce. Methods: Between Jan-02/2014 and June-20/2015 circulating 25-hydroxyvitamin-D (25-OH-D) levels were analyzed in 76% consecutive patients’ samples of a single individual cancer practice located in Gdansk, Poland. Three hundred forty seven patients (female: 72.5%, median age 64, range: 23-89 years; breast cancer: 57.8%, colon cancer 27.7%) were admitted for palliative care due to: disseminated cancer (18%), side effects of anticancer therapy (56.6%) or symptom control in non-cancer diseases (24.5%). Results of fast 25-OH-D blood tests were correlated with selected clinical factors. Results: The median 25-OH-D level of all our cohort patients was 15.85 ng/mL (range: 0.40 – 62.00 ng/mL); 65.0% of subjects were vitamin D deficient (25-OH-D < 20 ng/mL) and 23.5% insufficient (20-30 ng/mL); only 3.30% patients were taking vitamin D supplements before they entered the study. The univariate analysis identified the following risk factors for inadequate 25-OH-D levels: active cancer disease (median 25-OH-D: 12.50 ng/mL versus 17.86 ng/mL in patients without evidence of disease, p < 0.001) and current glucocorticoids use (at least 14 days within the last month: 11.58 ng/mL versus 17.12 ng/mL in glucocorticoids nonusers; p < 0.01). Age, gender, body mass index values, primary cancer location, dominant metastatic site and higher antibiotics use did not influence 25-OH-D levels. Conclusions: 1) Low (deficient or insufficient) 25-OH-D serum levels were highly prevalent in palliative cancer care outpatients, mostly in those with clinically active disease and using glucocorticoids; 2) the study will continue to address the correlation between 25-OH-D concentrations and symptom burden as well as the potential feasibility of vitamin D supplementation to improve symptoms management of patients in palliative care setting.
