Predictive and prognostic impact of the different features of tumor budding in stage II colorectal cancer.

Tumor budding is a significant independent prognostic factor in colorectal cancer. Routine reporting of tumor budding is now advocated for in the colorectal cancer standard approach recommended by the International Tumor Budding Consensus Conference guidelines. However, the current tumor budding assessment system only emphasizes tumor-budding quantity and ignores other features. Therefore, this study aimed to further determine the prognostic value of tumor budding based on a more comprehensive feature analysis. To this end, we conducted a retrospective pathology review of the different characteristics of tumor budding (that is quantity, structure, cell atypia, location, stromal reaction, and immunohistochemical phenotype) in 224 specimens of stage II colorectal cancer at our institution between 2009 and 2015. The mean age of the patients was 60.3 ± 9.2 years (range, 39-84 years). Among various features of tumor budding, single-cell budding, anaplasia-like cell atypia, myxoid stroma, high tumor budding quantity, and loss of CDX2 expression were independent predictors of recurrence and mortality in patients with stage II colorectal cancer. Based on these results, we suggest that in addition to tumor-budding quantity, other tumor budding features play important biological roles in the development of colorectal cancer. Our findings provide prognostic information that could help with guiding clinical management and oncology care models for patients with stage II colorectal cancer.
