We also explored on association of Toxoplasma gondii seropositivity with selected variables.Methods: This is a prospective cross-sectional study conducted at Prince Faisal bin Bandar cancer center, Qassim, Saudi Arabia, from November 2014 to March 2015. One hundred thirty seven patients were involved in the study. Demographic data was collected using structured questionnaire, and clinical information was retrieved from the patient’s medical reports. Enzyme-linked immunosorbent assay technique was used for antibody assay.Results: The frequency of seropositivity for Toxoplasma gondii infection was 30.6%. The patient’s age range from 1.5-84 years with a geometric mean of 42.7 years. The seropositivity was significantly higher (p<0.05) among the 40-80 years age group (71.4%) as compared to 0-39 years one (28.6%).Conclusion: The prevalence of Toxoplasma gondii increases with increasing age among cancer patients in this region of central Saudi Arabia. More research is advisable for better understanding of ageing in pathogenesis of toxoplasmosis among patients with malignancies.
