Abstract
Circulating tumor cells (CTCs) are novel biomarkers for liquid biopsy, emerging as a promising research area for colorectal cancer (CRC) management. However, the heterogeneity of CTC phenotypes poses a significant challenge for their reliable detection in blood. The heat shock protein 70 (HSP70) and chaperonin-containing TCP1 (TCP1) have crucial roles in cancer pathogenesis, but their clinical value for CTC characterization remains unknown. We assessed the expression status of the HSP70 and TCP1 in CRC-derived CTCs to evaluate their biomarker potential for CTC identification. Peripheral blood samples were collected from metastatic CRC (mCRC) patients. The enrichments of CTCs were performed by the AdnaTest protocol, and the expression status of the HSP70 and TCP1 was analyzed using PCR-based analysis. Additionally, we analyzed the correlations between these genes and CRC-specific markers (CEA, EGFR, and EpCAM) along with clinicopathological characteristics. HSP70 positivity was observed in 55.32% of mCRC patients, and TCP1 positivity was detected in only 6 samples. Nine samples that were negative for CRC-specific markers showed expressions of HSP70 and TCP1. Notably, no TCP1 positivity was seen in individuals who received more than five systematic treatments. Overall, this study highlights the importance of expanding CTC biomarker panels beyond conventional markers to capture the full spectrum of tumor cell diversity in circulation. Integrating novel molecular markers such as HSP70 and TCP1 may improve the sensitivity of CTC-based diagnostics and facilitate personalized monitoring of disease progression and treatment response in CRC patients.
