Mutant P53 Expression and Its Relationship with Degrees of Differentiation and Prognosis of Colorectal Adenocarcinoma at the Adam Malik Haji Hospital Medan

Introduction

Cancer is one of the most significant public health concerns worldwide, particularly in developing countries. According to the World Health Organization (WHO), approximately 10 million new cancer cases are diagnosed annually, with colorectal adenocarcinoma being one of the most common types of cancer, affecting men more than women. Colorectal adenocarcinoma accounts for around 90% of all colorectal carcinoma cases, and its development is primarily caused by genetic mutations, particularly the loss of function of the P53 tumor suppressor gene. This gene plays a crucial role in regulating cell cycles and apoptosis, and its mutations often lead to the loss of total and partial protein function.

The Role of the P53 Gene in Colorectal Carcinoma

The P53 gene is responsible for maintaining genetic integrity by regulating several essential activities, including the cessation of cell cycles, DNA repair, and apoptosis. When the function of P53 is disrupted due to mutations, the gene's ability to maintain the health of the body's cells is compromised. The accumulation of abnormal P53 protein in tumor cells can be detected using specific P53 antibodies. In colorectal carcinoma tissue, the overexpression of P53 mutants is often associated with a higher degree of histology of colorectal carcinoma and is related to high cell proliferation activity.

Research Objectives

This study aims to assess the expression of P53 mutants in determining the degree of differentiation and prognosis of colorectal adenocarcinoma in the anatomy pathology laboratory of Adam Malik Haji Hospital Medan. With an observational and cross-sectional approach, this study uses 59 samples of colorectal carcinoma tissue that have been diagnosed according to inclusion criteria. All samples are then colored using immunohistochemical techniques to determine the expression of P53 mutants.

Research Methodology

This study employed an observational and cross-sectional approach, using 59 samples of colorectal carcinoma tissue that met the inclusion criteria. The samples were then analyzed using immunohistochemical techniques to determine the expression of P53 mutants. The results of the analysis were then compared to the degree of histopathology of colorectal adenocarcinoma.

Research Results

The results of the analysis showed that the majority of patients were above 60 years old, with a total of 24 cases (40.68%). In terms of sex, more male patients were 36 cases (61.02%). The most common location of cancer was in the colon, with 36 cases (61.02%), and the majority were identified as adenocarcinoma that were well differentiated (well-differentiated adenocarcinoma) as many as 27 cases (45.76%).

The expression of the mutant P53 detected between the samples showed a score of +1 (weak) in 35 cases (59.32%). However, the results of the statistical analysis using the Chi-Square method showed that there was no significant difference between the expression of the mutant P53 and the degree of histopathology of colorectal adenocarcinoma, with a p-value of 0.427 (p-value > 0.05).

Conclusion

From the results of this study, it can be concluded that there is no significant difference between the expression of P53 mutants and histopathology grading in colorectal adenocarcinoma in the anatomy pathology laboratory of Adam Malik Hospital Medan. This discovery provides important insights for the development of further diagnostic and therapeutic strategies in handling colorectal cancer, as well as showing the need for further research to understand more about the role of the P53 gene in the course of this disease.

Implications and Future Directions

With further knowledge about the P53 gene, it is expected to find a new approach to the prevention and treatment of colorectal carcinoma, provide hope for patients, and improve their quality of life. This study highlights the importance of continued research into the role of the P53 gene in colorectal cancer and its potential applications in the development of new diagnostic and therapeutic strategies.

Limitations and Future Research Directions

This study has several limitations, including the small sample size and the use of a single hospital as the study site. Future studies should aim to recruit a larger sample size and include multiple hospitals to increase the generalizability of the findings. Additionally, further research is needed to understand the role of the P53 gene in the development and progression of colorectal cancer.

Recommendations for Future Research

Based on the findings of this study, several recommendations for future research are proposed. Firstly, further studies should aim to investigate the relationship between P53 mutant expression and the degree of histopathology of colorectal adenocarcinoma in a larger sample size. Secondly, studies should aim to explore the potential applications of P53 mutant expression in the development of new diagnostic and therapeutic strategies for colorectal cancer. Finally, further research is needed to understand the role of the P53 gene in the development and progression of colorectal cancer.

Conclusion

In conclusion, this study aimed to assess the expression of P53 mutants in determining the degree of differentiation and prognosis of colorectal adenocarcinoma in the anatomy pathology laboratory of Adam Malik Haji Hospital Medan. The results of the study showed that there was no significant difference between the expression of P53 mutants and histopathology grading in colorectal adenocarcinoma.

Q&A: Mutant P53 Expression and Its Relationship with Degrees of Differentiation and Prognosis of Colorectal Adenocarcinoma

Q: What is the P53 gene and its role in colorectal carcinoma?

A: The P53 gene is a tumor suppressor gene that plays a crucial role in regulating cell cycles and apoptosis. It helps to maintain genetic integrity by preventing the accumulation of mutations in cells.
