From: Serum chitinase activity prognosticates metastasis of colorectal cancer
Chitinase activity correlates with metastases and prognosticates metastases of primary colorectal cancer. a Kaplan-Meier analysis showed the chitinase activity in serum had significant correlation to survival in colorectal cancer patients. b Kaplan-Meier analysis showed CEA level in serum had significant correlation to survival in colorectal cancer patients. c Kaplan–Meier curves of metastasis probability of CRC patients without metastasis at first visit in the populations. It showed that patients with high chitinase activity have more metastasis risk compared with those with low chitinase activity. d Kaplan–Meier curve showed that CRC patients with high CEA level were no more likely to metastasize compared with CRC patients with low CEA level at Stage І-III (p = 0.4054). Log-rank test were performed in all figures. CRC, Colorectal Cancer
