Journal Article
Clinical significance of immunohistochemical expression of DDR1 and β-catenin in colorectal carcinoma
2023
Overview
Background
Despite recent advances in therapy modalities of colorectal cancer (CRC), it is still the third cause of cancer-related deaths worldwide. Thus, the search for new target therapies became mandatory. DDR1 is a collagen receptor that has a suggested role in cellular proliferation, tumor invasion, and metastasis.
Material and methods
Forty-eight cases of CRC, 20 of CR adenoma, and 8 cases of non-tumoral colonic tissue were subjected to immunohistochemistry by DDR1 and
β
-
catenin
antibodies. Results were compared among the different studied groups and correlated with clinicopathologic data and available survival data. Also, the expression of both proteins was compared versus each other. Results were compared among the 3 studied groups and correlated with clinicopathologic and survival data.
Results
It revealed a stepwise increase of DDR1 expression among studied groups toward carcinoma (
P
= 0.006). DDR1 expression showed a direct association with stage D in the modified Dukes’ staging system (
P
= 0.013), higher-grade histologic types (
P
= 0.008), and lymph node invasion (
P
= 0.028) but inverse correlation with the presence of intratumoral inflammatory response (TIR) (
P
= 0.001). The shortest OS was associated with strong intensity of DDR1 (
P
= 0.012). The DDR1 and
β
-
catenin
expressions were significantly correlated (
P
= 0.028), and the combined expression of both was correlated with TNM staging (
P
= 0.017).
Conclusion
DDR1 overexpression is a frequent feature in CRC and CR adenoma. DDR1 is a poor prognostic factor and a suppressor of the TIR. DDR1 and
β
-
catenin
seem to have a synergistic action.
