METHODS: CRC patients in an Institutional Review Board approved data/plasma bank who underwent elective MICR for whom preoperative(PreO p), early postoperative(PostO p), and 1 or more late PostO p samples [postoperative day(POD) 7-27] available were included. Plasma CHi3L1 levels(ng/m L) were determined in duplicate by enzyme linked immunosorbent assay. RESULTS: PreOp and PostOp plasma sample were available for 80 MICR cancer patients for the study. The median PreOp CHi3L1 level was 56.8 CI: 41.9-78.6 ng/mL(n = 80). Significantly elevated(P < 0.001) median plasma levels(ng/mL) over PreOp levels were detected on POD1(667.7 CI: 495.7, 771.7; n = 79), POD 3(132.6 CI: 95.5, 173.7; n = 76), POD7-13(96.4 CI: 67.7, 136.9; n = 62), POD14-20(101.4 CI: 80.7, 287.4; n = 22), and POD 21-27(98.1 CI: 66.8, 137.4; n = 20, P = 0.001). No significant difference in plasma levels were noted on POD27-41. CONCLUSION: Plasma CHi3L1 levels were significantly elevated for one month after MICR. Persistently elevated plasma CHi3L1 may support the growth of residual tumor and metastasis.展开更多

Monocyte chemotactic protein-1(MCP-1) levels(pg/mL) were determined via enzyme linked immuno-absorbent assay. RESULTS: One hundred and two CRC and 86 BEN patients were studied. The CRC patient's median preoperative MCP-1 level(283.1, CI: 256.0, 294.3) was higher than the BEN group level(227.5, CI: 200.2, 245.2; P = 0.0004). Vs CRC preoperative levels, elevated MCP-1 plasma levels were found on postoperative day 1(446.3, CI: 418.0, 520.1), postoperative day 3(342.7, CI: 320.4, 377.4), postoperative day 7-13(326.5, CI: 299.4, 354.1), postoperative day 14-20(361.6, CI: 287.8, 407.9), and postoperative day 21-27(318.1, CI: 287.2, 371.6; P < 0.001 for all). CONCLUSION: Preoperative MCP-1 levels were higher in CRC patients(vs BEN). After MICR for CRC, MCP-1 levels were elevated for 1 mo and may promote angiogenesis, cancer recurrence and metastasis.展开更多
