ABSTRACT
<p><b>OBJECTIVE</b>To detect microsatellite instability(MSI) in colorectal cancer by fluorescence multiplex polymerase chain reaction(FM-PCR) and explore its clinical value.</p><p><b>METHODS</b>MSI of 110 colorectal cancer patients undergone surgical resection in our department from 2004 to 2005 were examined by FM-PCR, and the pathological characteristics were compared between MSI and microsatellite stable (MSS) colorectal cancer patients.</p><p><b>RESULTS</b>Among 110 cases, the male were 66 and the female were 44. Mean age was 60.8 (26-94) yrs. All 5 microsatellite markers were amplified. Out of them, 10 cases (8.1%) were MSI-H, 13 cases (11.8%) were MSI-L and 87 cases (79.1%) were MSS. Instability of BAT-26 was found in 9 cases (8.2%), BAT-25 was in 11 cases (10.0%), D2S123 was in 11 cases (10.0%), D5S346 was in 6 cases (8.2%) and D17S250 was in 8 cases (7.3%). Age between MSI and MSS colorectal cancer patients was significant and other pathological characteristics were not significant.</p><p><b>CONCLUSIONS</b>FM-PCR is a clinically stable method for MSI detection in colorectal cancer patients. There are no significant differences between MSI and MSS pathological characteristics of colorectal cancer patients.</p>
