The Relationship Between P38 MAPK Expression and Histopathological Type in Patients with Nasopharyngeal Carcinoma

Introduction

Nasopharyngeal carcinoma (KNF) is a type of cancer that affects the nasopharynx, the upper part of the throat behind the nose. It is a significant health concern in Indonesia, with over 13,000 new cases reported each year. The disease is characterized by its aggressive nature and high mortality rate. Understanding the molecular mechanisms underlying KNF is crucial for developing effective treatment strategies. One of the key proteins involved in the development of KNF is P38 MAPK, a protein kinase that plays a crucial role in various cellular processes, including proliferation, differentiation, migration, and apoptosis.

Background

P38 MAPK is a member of the mitogen-activated protein kinase (MAPK) family, which is involved in the regulation of cellular responses to various stimuli, including stress, cytokines, and growth factors. Previous studies have shown that P38 MAPK plays a dual role in cancer development, with both tumor-suppressive and tumor-promoting effects. In the context of KNF, P38 MAPK has been implicated in the regulation of tumor growth, invasion, and metastasis.

Methodology

This study aimed to investigate the relationship between P38 MAPK expression and histopathological type in patients with KNF. A total of 126 patients diagnosed with KNF at the Adam Malik Hajj General Hospital between February and December 2019 were included in the study. The diagnosis was based on a combination of clinical history, physical examination, and histopathological biopsy. Immunohistochemical techniques were used to evaluate the expression of P38 MAPK in the biopsy tissue samples. The immunoreactive score was used to determine the level of P38 MAPK expression, with scores ≥ 4 considered positive or overexpressed.

Results

The results of the study showed that KNF most commonly occurred in the age group 41-60 years (57.1%), male (71.4%), with non-Keratinizing SCC histopathology (79.4%), and stage IV (54.8%). Further analysis revealed that the expression of P38 MAPK was more commonly found in patients with Non-Keratinizing SCC histopathology (81.0%), T3-T4 tumor stage (97.1%), N3 lymph nodes (100%), and Clinical Stadium III-IV (96.8%).

Discussion

The findings of this study suggest that there is a significant correlation between the expression of P38 MAPK and the size of the primary tumor, enlargement of the neck lymph nodes, and clinical stage. However, no significant relationship was found between the expression of P38 MAPK and the KNF histopathology type. This suggests that P38 MAPK may play a role in the development of KNF, particularly at an advanced stage. The high expression of P38 MAPK in non-keratinizing SCC may indicate higher tumor aggressiveness.

Conclusion

In conclusion, this study provides new insights into the relationship between P38 MAPK expression and histopathological type in patients with KNF. The findings suggest that P38 MAPK may play a role in the development of KNF, particularly at an advanced stage. Further research is needed to understand the mechanism of work of P38 MAPK in KNF and the potential for developing therapeutic strategies that target the P38 MAPK pathway.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research is needed to understand the mechanism of work of P38 MAPK in KNF and the potential for developing therapeutic strategies that target the P38 MAPK pathway.
Public awareness of KNF and risk factors, such as exposure to the Epstein-Barr virus, salted fish consumption, and smoking habits, should be increased.
Efforts should be made to increase access to appropriate diagnostic and therapy services for KNF patients in Indonesia.

Limitations

This study has several limitations, including the small sample size and the use of a single hospital as the study site. Further studies with larger sample sizes and multiple study sites are needed to confirm the findings of this study.

Future Directions

Future studies should focus on understanding the mechanism of work of P38 MAPK in KNF and the potential for developing therapeutic strategies that target the P38 MAPK pathway. Additionally, studies should investigate the relationship between P38 MAPK expression and other molecular markers in KNF.

Abstract

This study investigated the relationship between P38 MAPK expression and histopathological type in patients with nasopharyngeal carcinoma. The results showed that P38 MAPK expression was more commonly found in patients with Non-Keratinizing SCC histopathology, T3-T4 tumor stage, N3 lymph nodes, and Clinical Stadium III-IV. However, no significant relationship was found between P38 MAPK expression and KNF histopathology type. The findings suggest that P38 MAPK may play a role in the development of KNF, particularly at an advanced stage. Further research is needed to understand the mechanism of work of P38 MAPK in KNF and the potential for developing therapeutic strategies that target the P38 MAPK pathway.
