Significant morbidity and mortality occur in immunocompromised hosts as a result of parasite
infections. Cancer patients have impaired immune systems, either due to the illness itself or as
a result of immunosuppressive medications or treatments. In this study, parasitic infections in
patients with intestinal cancer from Sohag Hospitals and Sohag Oncology Center's Clinical
Oncology and Nuclear Medicine department were assessed. Between April and October of
2023, a total of 100 stool samples were taken from outpatient clinics; another 100 stool samples
were taken from the healthy control group. Every sample that was gathered was split into
three sections: the first was used for microscopic and macroscopic analysis, the second was
kept for later use and preservation, and the third was cultivated to identify Strongyloides stercoralis.
In contrast to 21% (21 instances) in controls, 45% (45 cases) of patients with intestinal
cancers (24 with colon cancer and 21 with rectal cancer) had intestinal parasites. According to
the data, Blastocystis hominis was the most prevalent
