Abstract
It is increasingly appreciated that host factors within the tumor centre and microenvironment play a key role in dictating colorectal cancer (CRC) outcomes. As a result, the metastatic process has now been defined as a result of epithelial‐mesenchymal transition (EMT). Establishment of the role of EMT within the tumor centre and its effect on the tumor microenvironment would be beneficial for prognosis and therapeutic intervention in CRC. The present study assessed five immunohistochemical EMT markers within the tumor centre on a 185 stage II/III CRC patient TMA. In 185 patients with CRC; cytoplasmic snail (HR 1.94 95% CI 1.15‐3.29, p=0.012), and a novel combined EMT score (HR 3.86 95% CI 2.17‐6.86, p<0.001) were associated with decreased cancer‐specific survival. The combined EMT score was also associated with increased tumor budding (p=0.046), and systemic inflammation (p=0.007), as well as decreased memory T‐cells within the stroma (p=0.030) and at the invasive margin (p=0.035). Furthermore, the combined EMT score was associated with cancer specific survival independent of TNM‐stage (HR 4.12 95% CI 2.30‐7.39, p<0.001). In conclusion, a novel combined EMT score stratifies patient's survival in stage II/III CRC and associates with key factors of tumor metastasis. Therefore, the combined EMT score could be used to identify patients at risk of micrometastases and who may benefit from standard adjuvant therapy, potentially in combination with EMT blockade.
