Summary
The volume-corrected mitotic index (M/V index) is a key predictor of patient prognosis in oral squamous cell carcinomas. This M/V index also correlates with DNA ploidy, offering similar prognostic insights.
Area of Science:
- Oncology
- Pathology
- Cancer Research
Background:
- Oral squamous cell carcinoma (OSCC) is a significant global health concern.
- Accurate prognostic indicators are crucial for effective OSCC patient management.
- Existing histopathological and clinical indices have limitations in predicting OSCC outcomes.
Purpose of the Study:
- To evaluate the prognostic value of the volume-corrected mitotic index (M/V index) in OSCC.
- To compare the M/V index with traditional histopathological and clinical prognostic factors.
- To investigate the relationship between the M/V index and DNA ploidy in OSCC.
Main Methods:
- Analysis of 50 OSCC tumors.
- Estimation of volume-corrected mitotic index (M/V index).
- Univariate and multivariate survival analyses (Cox regression model).
- Assessment of DNA ploidy.
Main Results:
- Histological malignancy, mode of invasion, and M/V index significantly correlated with survival (univariate analysis).
- The M/V index emerged as the strongest predictor of patient prognosis in multivariate analysis.
- Significant correlation observed between M/V index and DNA ploidy.
Conclusions:
- The M/V index is a valuable prognostic factor for oral squamous cell carcinoma.
- M/V index and DNA ploidy provide comparable prognostic information.
- The M/V index offers a reliable method for predicting OSCC patient outcomes.
