Clinical Trial Summary
The investigators examined circulating tumor cells (CTC) in the perioperative peripheral
blood of hundreds of HCC patients undergoing liver cancer surgery using CellSearch technology
between 2013 and 2016. Although the investigators have done a preliminary study of the above
data and published some results, the previous study was only a basic analysis. Now the
investigators plan to carry out further in-depth analysis of these data, including
hospitalization data, follow-up results, surgical tumors and blood specimens, and make full
use of biostatistics, molecular biology, pathology and other related techniques to elucidate
the association between the levels of CTC or CTC clusters and patients' disease during the
perioperative period, and to explore the molecular basis of CTC production in hepatocellular
carcinoma.
Description:
From 2013 to 2016, CellSearch technology was used to detect the number of circulating tumor
cells (CTC) in peripheral blood of hundreds of HCC patients undergoing liver cancer surgery
during perioperative period. The analysis results confirmed that the level of CTC before and
after surgery were significantly correlated with overall survival (OS) and disease-free
survival (DFS) of patients. CTC level changed before and after surgery, but there was no
statistical difference. Preoperative CTC was more correlated with patients' disease-related
clinical parameters, while postoperative CTC was an independent prognostic indicator of
patients after surgery. In addition, the investigators' study found that CTC clusters level
can be a new marker of tumor progression in HCC patients.
Based on the above data, the investigators will perform retrospective analysis to compare the
relationship between CTC level and clinical indicators of HCC patients. Participants were
divided into groups according to pathological type, differentiation degree, clinical stage,
invasion degree, recurrence and metastasis of tumors. Combined with immunohistochemistry and
quantitative PCR results, the correlation of CTC in tumor genesis, pathological model, degree
of differentiation, tumor stage, invasion, metastasis and expression of other tumor markers
was studied.
