Results

The graphs of Fig. 5 showed the mean of Angles A, B, and C and the mean of θ₁ and θ₂ in each, and the pathological diagnosis of solid type, tubule forming type, and scirrhous type was made.

It is shown that θ₁ value decreases in the order of solid type, tubule forming type, and scirrhous type.

The tissue was classified according to the classified TIC form pattern as Angle A = 94.3%, Angle B = 5.7%, Angle C = 0.0% in the solid type; Angle A = 5.7%, Angle B = 85.7%, Angle C = 8.6% in the tubule forming type; and Angle A = 0.0%, Angle B = 8.6%, Angle C = 91.4% in the scirrhous type.

When the amount of the traits of solid type were set to Angle A, tubule forming type to Angle B, and scirrhous type to Angle C, θ₁ of scirrhous type (P = 5.09E-06) was a value much lower than that of tubule forming type and solid type.

The sensitivity, specificity, and positive predictive value according to each tissue in 105 cases were 94.3%, 97.1%, 94.3% in the solid type, 85.7%, 92.9%, 85.7% in the tubule forming type, and 91.4%, 95.7%, 91.4% in the scirrhous type, respectively (Fig.6, Table,1).
