Abstract:
Background: Nutritional factors in developing some malignancies have been investigated
recently.
Objective: In this study, we evaluated the role of vitamin D in advanced laryngeal cancer and its association
with the development of pharyngocutaneous fistula (PCF) following total laryngectomy.
Study Design: A cross-sectional, case-control study was conducted.
Methods: Fifty-five patients with advanced laryngeal cancer referred for total laryngectomy were
included. We also considered 55 healthy individuals after matching age and sex as a control group.
Serum levels of 25(OH)D3 were measured using a commercially available enzyme-linked immunosorbent
assay (ELISA) kit. The association of serum 25(OH)D3 with PCF following total
laryngectomy was also determined.
Results: Vitamin D was significantly lower in patients with advanced laryngeal cancer than in the
control group (p < 0.001). Moreover, our results showed that a mean serum concentration of
25(OH)D3 in patients with PCF was significantly lower than in patients without PCF (p < 0.001).
Conclusion: Vitamin D deficiency is highly prevalent in advanced laryngeal cancer, most pronounced
in those who develop a PFC following total laryngectomy.
