Hypothesis
The local immune response represented by peritumoral inflammatory infiltrate is a possible prognostic factor in squamous cells carcinoma.
Conclusion
The study suggests that a strong cellular immune response, indicated by a high number of T lymphocytes and macrophages, may be associated with better prognosis in oral squamous cell carcinoma.
Supporting Evidence
- The study found that T lymphocytes were the most abundant in the inflammatory infiltrate.
- Undifferentiated tumors showed a higher expression of Ki-67, indicating greater cell proliferation.
- Statistical analysis revealed significant differences in inflammatory area between well-differentiated and undifferentiated tumors.
Takeaway
This study looked at how the immune system reacts to a type of mouth cancer and found that a strong immune response might help patients do better.
Methodology
Oral mucosa samples from patients were analyzed for histological classification and the phenotypical profile of peritumoral inflammatory infiltrate using immunohistochemical methods.
Limitations
The study does not fully clarify the relationship between inflammation intensity and patient prognosis, indicating a need for further research.
Participant Demographics
