Description
Summary:Background: There is a lack of information regarding Vitamin D deficiency in treatment-naive cancer patients. Aim: The aim of this was to study the prevalence of Vitamin D deficiency in cancer patients. Objectives: The objective was to measure the extent of Vitamin D insufficiency and deficiency in treatment-naive consecutive individual cancer patients from Eastern India. Materials and Methods: All consecutive new patients seen between April 2019 and September 2019 were offered a baseline test to measure serum 25-hydroxy Vitamin D [25 (OH) D] levels along with routine investigations. Vitamin D insufficiency was diagnosed when serum 25 (OH) D level was between 20 and 30 ng/mL, whereas patients with a level <20 ng/mL were designated as Vitamin D deficient. Patients with a Vitamin D level <10 ng/mL were termed as having severe Vitamin D deficiency. Descriptive statistics and frequency distribution were used in SPSS software, and Pearson's Chi-squared test was used to compare between the categorical variables. Results: Of 252 patients, 140 (56%) were female; median age was 51 years (range, 19–84 years) and 204 (81%) were diagnosed with solid organ malignancies. Mean (±standard deviation) Vitamin D level was 18.94 (±10.4). 169/252 (67%) had Vitamin D deficiency, whereas another 52/252 (21%) had Vitamin D insufficiency. Among these, 44/169 (26%) had severe Vitamin D deficiency. Females were more deficient compared to males, 76% versus 55% (P = 0.002). Vitamin D deficiency in younger (<50 years) and older (>50 years) population was 73% and 61% (P = 0.144); while that in solid versus hematolymphoid malignancies was 69% versus 58% (P = 0.173). In the three most common tumors, namely breast (21%), colorectal (8%), and ovary (8%), Vitamin D deficiency was noted in 75% of patients in each group. Vitamin D deficiency was the highest (84%) in esophageal and stomach cancer patients. Conclusion: More than two-thirds of Indian cancer patients are Vitamin D deficient. Patients with upper gastrointestinal, breast, colorectal, and ovarian cancers and female patients are the most vulnerable groups.
