Survival Trends Associated With Histopathological Risk Factors in Oral Squamous Cell Carcinoma.

Area of Science:

• Oncology
• Pathology
• Cancer Research

Background:

• Histopathological risk models for oral squamous cell carcinoma (OSCC) have limited success in patient stratification.
• Key features like perineural invasion (PNI) and worst pattern of invasion are underutilized in current staging.
• There's a need to integrate these histological indicators for better prognosis prediction.

Purpose of the Study:

• To assess and characterize histological prognostic indicators in OSCC.
• To elucidate the significance of these indicators in relation to patient prognosis.
• To develop a risk assessment model correlating indicators with survival and risk stratification.

Main Methods:

• Retrospective chart audit of OSCC cases.
• Histologic parameters staged using AJCC 8th Edition and CAP Protocol 2018.
• Pearson's chi-square and Kaplan-Meier survival analyses were employed.

Main Results:

• Higher grades of invasion patterns correlated with increased PNI and depth of invasion (p < 0.05).
• Depth of invasion was significantly associated with extranodal extension (ENE) (p < 0.05).
• Worst pattern of invasion, depth of invasion, and PNI emerged as predictors of poorer survival.

Conclusions:

• A risk stratification model based on these histological indicators can enhance patient outcomes.
• Integrating detailed histopathological analysis improves survival rates and treatment efficacy in OSCC.
• The study highlights the importance of specific histological features for accurate OSCC risk assessment.
