Background: Despite continued and comprehensive planning of the world health organization (WHO), intestinal parasitic infections are a serious public problem in developing countries. Due to the high prevalence of cancers in Ardabil province and subsequently the high possibility of intestinal parasitic infections among the people, the aim of this study was to assess the frequency of intestinal parasites in patients with malignancy in this area.Methods: In this cross-sectional study, 100 fecal samples were collected from patients with cancer during February to September 2015. The specimens were examined for intestinal parasites using direct smear, formol-ethyl acetate concentration, agar plate culture and Ziel-Neelsen staining technique.Results: The overall frequency of intestinal parasitic infections in studied cancer patients was 10%. The infection rates of detected intestinal parasites were Cryptosporidium spp. oocyst 4%, Blastocystis hominis 3%, Giardia lamblia 2% and Taenia spp. 1%.Conclusion: Despite the low frequency of intestinal parasites, there is a need to screen cancer patients for some important parasitic infections such as Cryptosporidium spp. and Strongiloides stercoralis because of irreparable effects of those parasites on thepatients and to increase awareness among clinicians regarding the occurrence of parasitic infections in these patients.
