- Аннотация: Cancer-associated fibroblasts (CAFs) — mesenchymal cells in the tumor stroma, play one of the leading roles in tumor progression in many different tumors, including colorectal cancer. Scientists have described many markers for CAFs, but none of them is specific. We performed immunohistochemistry tests using five antibodies (αSMA, POD, FAP, PDGFRα, PDGFRβ) to investigate CAFs in three zones of 49 colorectal adenocarcinomas: apical, central, and invasive edge. We revealed the reliable correlation between high PDGFRβ and PDGFRα value in the apical zone and deeper invasion (T3–T4) (p = 0.0281 and p = 0.0137). High αSMA level in apical zone (p = 0.0001), αSMA level in central zone (p = 0.019), POD level in apical zone (p = 0.0222), POD level in central zone (p = 0.0206) and PDGFRβ level in apical zone (p = 0.014) correlated reliably with the presence of metastasis in lymphatic nodules. For the first time, focused on the inner layer of CAF adjacent to tumor complexes. We observed that cases with inner αSMA expression were significantly more often (p = 0.023) characterized by the presence of regional lymph node metastasis compared with cases with mix of CAF markers (p = 0.007) and with cases with inner POD expression (p = 0.024). The found relationships between the level of markers and the presence of metastases indicate their clinical significance.
