Screening of toxoplasmosis in cancer patients: a concern

Toxoplasmosis is an opportunistic infectious disease in immunocompromised patients, including cancer patients, whose detection is by molecular and serological methods. A total of 106 blood samples from patients with different types of cancer were evaluated for anti-Toxoplasma gondii IgG and IgM antibodies by the enzyme-linked immunosorbent assay (ELISA) and the parasite DNA by nested polymerase chain reaction (PCR). These were detected in 41.51% (44/106) and 0.94% (1/106), respectively, but T. gondii IgM antibody was not detected at all. These results suggest that the screening of toxoplasmosis should be considered more routinely in cancer patients
