ABSTRACT
Objective:
To evaluate the effect of intraoperative cell salvage (ICS) on the number and viability of cancer cells in salvaged autologous blood from the patients undergoing liver cancer surgery.Methods:
Twenty patients undergoing open radical primary hepatocellular carcinoma were selected, and blood from the operative field was collected after exposing the liver and treated with ICS. Blood specimens 20 ml from the surgical field (S 1), blood specimens 20 ml before ICS treatment-leukocyte depletion filter (LDF) filtration (S 2) and blood specimens 20 ml after LDF filtration (S 3) were collected and enriched, of which the blood sample 10 ml was used for cancer cell identification and count by immunofluorescence staining, and the remaining blood sample 10 ml was continuously cultured for 3 weeks, and then cell viability was observed by immunofluorescence method.Results:
Hepatocellular carcinoma(HCC) cells were identified in 19 S 1 specimens, 18 S 2 specimens, and 16 S 3 specimens, but there was no significant difference in the detection rate among the three specimens ( P>0.05). Compared with S 1 specimens, HCC cell count was significantly reduced in S 2 and S 3 specimens ( P<0.05). There was no significant difference in the HCC cell count between S 3 specimens and S 2 specimens ( P>0.05). After 3 weeks of culture, the results of light microscopy showed that hepatocellular carcinoma cell clusters were found in S1 specimens, and no hepatocellular carcinoma cell cluster was found in S 2 and S 3 specimens; the results of fluorescence microscopy showed that 400 and 14 mixed epithelial-mesenchymal HCC cells and 100 and 21 mesenchymal HCC cells were found in S 1 and S 2 specimens, respectively, while no HCC cells were identified in S 3 specimens, among which HCC cells mainly presented as clusters of hepatocellular carcinoma cells in S 1 specimen, while no clusters of hepatocellular carcinoma cells were found in S 2 and S 3 specimens.Conclusions:
After treatment with ICS or ICS-LDF, the number and viability of hepatocellular carcinoma cells in salvaged autologous blood are significantly reduced, and hepatocellular carcinoma cells exist as single cells and fail to develop clusters of hepatocellular carcinoma cells; LDF can reduce the risk of hepatocellular carcinoma cell autotransfusion to a certain extent, although it can not effectively filter out hepatocellular carcinoma cells continuously.
