Carcinoembryonic Antigen (CEA) Immunoexpression Display In Ulcerous Colitis Lesions, Dysplasia And Adenocarcinoma Colon

Carcinoembryonic Antigen (CEA) Immunoexpression Display in Ulcerous Colitis Lesions, Dysplasia, and Adenocarcinoma Colon: A Comprehensive Review

Ulcerous colitis is a non-specific inflammatory disease that has the potential to become cancer. The incidence of ulcerous colitis has increased significantly over the last two decades, with a substantial proportion of cases undergoing a dysplasia process and a high risk of developing into colorectal carcinoma. Carcinoembryonic antigen (CEA) levels have been shown to increase in ulcerous colitis, serving as a preoperative marker for poor prognosis in colorectal carcinoma. This study aims to investigate the CEA immunoexpression in tissues diagnosed with colorectal carcinoma, ulcerous colitis, dysplasia, and adenocarcinoma colon.

Ulcerous colitis is a chronic inflammatory disease of the colon that is characterized by ulcers and inflammation in the lining of the colon. The exact cause of ulcerous colitis is unknown, but it is believed to be related to a combination of genetic, environmental, and immune system factors. The disease can be classified into two main types: ulcerative proctitis and ulcerative colitis. Ulcerative proctitis is limited to the rectum, while ulcerative colitis affects the colon and rectum.

The incidence of ulcerous colitis has increased significantly over the last two decades, with a substantial proportion of cases undergoing a dysplasia process and a high risk of developing into colorectal carcinoma. Data shows that 25% of cases of ulcerous colitis can undergo a dysplasia process after 20 years, and up to 43% of cases are at risk of developing into colorectal carcinoma after more than 25 years. The diagnosis of ulcerous colitis can be confirmed through the CEA expression, which is a preoperative marker for poor prognosis in colorectal carcinoma.

This study involved 46 colony tissue specimens which had previously been diagnosed as ulcerous colitis, dysplasia, and colorectal adenocarcinoma. The analysis was carried out qualitatively related to CEA using the immunohistochemical method, where the results were classified based on the level of intensity: light and strong.

Of the 46 samples analyzed, 40 showed the results of positive staining on the cell membrane and cytoplasm (87%). This includes 20 cases with intensity (+1), 5 cases (+2), and 15 cases (+3). Of the total 12 cases with the results of coloring (+3) that spread, all of these cases were adenocarcinoma, with 3 of them identified as dysplasia. Of all cases of ulcerous colitis examined, 20 cases showed the results of coloring (+1), but 6 of them were not detected at all.

Statistical data shows that lesions diagnosed earlier through histopathology show a significant relationship with CEA immunoexpression. The results of this study suggest that adenocarcinoma and dysplasia show high intensity associated with poor prognosis, while ulcerous colitis shows moderate to low intensity, which indicates better prognosis.

Based on the results of the study, adenocarcinoma and dysplasia show high intensity associated with poor prognosis. Meanwhile, ulcerous colitis shows moderate to low intensity, which indicates better prognosis. This study provides an important picture of the relationship between CEA immunoexpression and prognosis in ulcerous colitis lesions, dysplasia, and adenocarcinoma of colon, and emphasizes the need for strict supervision in ulcerous colitis patients for early detection of the development of dysplasia and colorectal cancer.

A deeper understanding of this interaction can help in clinical management and preventive strategies for patients with ulcerous colitis, while improving the quality of their lives. The results of this study suggest that CEA immunoexpression can be used as a biomarker for early detection of dysplasia and colorectal cancer in ulcerous colitis patients. This can lead to early intervention and improved outcomes for patients with ulcerous colitis.

Further studies are needed to confirm the findings of this study and to explore the potential of CEA immunoexpression as a biomarker for early detection of dysplasia and colorectal cancer in ulcerous colitis patients. Additionally, studies are needed to investigate the relationship between CEA immunoexpression and other biomarkers for ulcerous colitis, such as inflammatory markers and genetic markers.

This study had several limitations, including the small sample size and the limited number of cases with high intensity CEA immunoexpression. Additionally, the study was limited to a single institution and may not be representative of all patients with ulcerous colitis.

In conclusion, this study provides an important picture of the relationship between CEA immunoexpression and prognosis in ulcerous colitis lesions, dysplasia, and adenocarcinoma of colon. The results of this study suggest that adenocarcinoma and dysplasia show high intensity associated with poor prognosis, while ulcerous colitis shows moderate to low intensity, which indicates better prognosis. This study emphasizes the need for strict supervision in ulcerous colitis patients for early detection of the development of dysplasia and colorectal cancer.
