KI-67 as a predictive indicator of papillary thyroid cancer in Iraqi patients.

Background: KI-67 (MKI-67 in humans) is a protein able to bind to DNA which contributes to cell growth and cell proliferation. KI-67 is currently considered as a biomarker that is widely utilized as prognostic indicator for evaluating cell proliferation, diagnosing diseases, and conducting research. Several different kinds of cancer have high Ki-67 expression, which simplifying the choice of treatment for individuals with various cancer types.

Aim: The objective was to evaluate the expression of KI67 in patients suffering papillary thyroid cancer (PTC) also the association between patients age and gender and KI67 expression.

Materials and methods: To undertake an in-depth investigation of KI67 in malignant and normal tissues, we used thyroid tissue sections to analyze KI67 expression in 70 samples, 50 different PTC (44 female and 6 male), and 20 normal types (10 for each gender). Each group's average age is between 20 and 60.

Results: The analysis of the data revealed a substantial difference in the expression of ki67 between the patients and control groups. Ki67 expression and either gender or age did not significantly correlate.

Conclusion: This study suggest that KI67 may be a crucial marker for assessing the aggressiveness of tumors and inflammatory diseases.
