There has been a recent increase in the number of small @entity1358 ( @entity1358 ) cases, particularly in pT1a cases. The prognostic parameters for small @entity1358 , however, are not well described. Herein, we assess the pathological parameters of pT1a @entity1 . Various clinicopathological parameters were analyzed in 293 @entity1 with pT1a @entity1358 without pre-operative @entity3 to predict the disease-free survival rate (DFS) and the @entity5 -specific survival rate (CSS). Clinicopathological parameters included age, @entity5 location, Fuhrman grade, @entity1350 ( @entity1350 ), @entity5 @entity39 , and growth pattern (expansive or infiltrative). In the univariate analysis, Fuhrman grade (grade 1 + 2 vs. 3 + 4), @entity1350 , growth pattern, and @entity5 @entity39 were parameters associated with a worse prognosis (P < 0.0001) in both the DFS and CSS. In the multivariate analysis, Fuhrman grade (P = 0.0048), growth pattern (P = 0.0275), and @entity5 @entity39 (P = 0.0188) were statistically significant in the DFS. Fuhrman grade (P = 0.0189) and growth pattern (P = 0.0016) were also statistically significant in the CSS. Fuhrman grade, @entity5 @entity39 , and growth pattern were independent prognostic parameters in pT1a @entity1358 . Growth pattern, a previously unrecognized parameter for prognosis, can be considered a new prognostic parameter in @entity1358 .

The post-operative pathological prognostic parameters of XXXX in pT1a cases.
