title: Clinical interest of the combined use of serum CD26 and alpha-L-fucosidase in the early diagnosis of colorectal cancer.
abstract: The purpose of this study was to assess if the combination of CD26 and alpha-L-fucosidase has a role in the diagnosis of colorectal cancer, paying particular attention to the stages in which the tumour is not yet disseminated. CD26 concentration and alpha-L-fucosidase activity were determined in sera from 110 colorectal cancer patients and 46 donors. The combination of CD26 and alpha-L-fucosidase showed a specificity of 100% with a sensitivity of 64% in the diagnosis of colorectal cancer. Interestingly, the combination of both markers had a sensitivity of 75% in the stage I at the highest specificity (100%), providing also high sensitivity levels for the other non-disseminated stages (66% for stages II and III). In conclusion, the combined use of CD26 and alpha-L-fucosidase offers high sensitivity with high specificity in the diagnosis of colorectal cancer, especially at the earliest stage (TNM I).
