Background: Different immunostain markers have improved the early diagnosis of cancer, facilitating early-stage treatment. One of these stains was the special AT-rich sequence-binding protein-2 (SATB2), which serves as a diagnostic marker, and its expression may offer prognostic and predictive insights. Objectives: To evaluate the immunohistochemical expression of SATB2 in colorectal carcinoma cases and its relationship with some clinicopathological parameters and its expression with the expression of each β-hCG and Cyclin D1. Methods: This retrospective case series study examined fifty paraffin-embedded blocks of colorectal carcinoma from October 2024 to August 2025 that were collected from Al-Jamhuri Teaching Hospital and some private laboratories in Mosul City, which had already been studied by immunostains of β-hCG and Cyclin D1. Investigation of SATB2 by immunohistochemistry was done. Results: SATB2 was detected in 54% of the cases, mostly in individuals older than 50 years (88.9%). Grade II differentiation is found in 59.2% of these cases, while depth of invasion at the level of T3 and T4 is 85.1%, and lymphovascular invasion constitutes 62.9%. Expression of negative lymph node involvement was observed in 59.3% of cases, with 48.1% of patients at stage II; among the positive cases of SATB2, 85.1% showed high expression of cyclin D1, while 59.2% showed positive β-hCG expression. Conclusions: SATB2 is expressed in 54% of cases in patients over 50 years old, females, and Grade II. SATB2 is strongly associated with the high expression of cyclin D1 and, to a lesser extent, with β-hCG expression.
