The Significance of Opportunistic Parasitosis and Blastocystosis in Patients with Gastric Cancer: a Study with Control Group.

OBJECTIVE

The aim of this study was to determine the prevalence of opportunistic parasites and spp. in patients with gastric cancer (CA) and to determine the significance of these parasite.

METHODS

The patient group and the control group were composed of 100 people each. The stool samples were examined under the microscope for intestinal parasites with the native-Lugol method. Then, samples were multiplied by formol-ethyl acetate method and stained with modified acid-fast method.

RESULTS

Intestinal parasite positivity was indicated in 14% of the gastric CA, and 2% of the healthy individuals (p=0.001). spp. (p=0.009) was identified in 11%, spp. was identified in 4%, was identified in 2%, and was identified in 1% of the patient group. There were significant differences between the intestinal parasite positivity (p=0.012), abundant spp. positivity (p=0.041) and all Blastocystis spp. positivity (p=0.037) in patient and control groups. Most of the patients who were positive for parasites had diarrhea.

CONCLUSION

Based findings, it was concluded that it would be beneficial to evaluate gastric CA patients, especially those with diarrhea, for intestinal parasites.
