The ability to classify early oral tongue SCCs into a component of HRS, was also an independent prognostic factor (HR, low-risk and high-risk categories would represent a major advancement 4.47; 95% CI, 1.59-12.51). Even if it is there, it does not always mean that your cancer has spread. Head And Neck, 36(6), 811-818. a WPOI 1: broad pushing invasion.

Kaplan-Meier curves for disease-free survival revealed prognostic association with nodal involvement, tumor size, worst WHO grading; most common pattern of invasion and invasive pattern grading score (sum of two most predominant patterns of invasion). The trained network was used to evaluate several prognostic parameters (age, gender, T stage, WHO histologic grade, depth of invasion, tumor budding, worst pattern of invasion, perineural invasion, and lymphocytic host response). a WPOI 1: broad pushing invasion.b WPOI 2: finger-like tumor front.c WPOI 3: large tumor islands > 15 cells.d-f WPOI 4: small tumor islands 15 cells.g POI 5: satellite nodule(s) at least 1 mm away from the main tumor.
