Objective To discuss the influence of combination of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) for preoperative assessment on colon cancer surgery strategy.
Methods The examination data of 110 patients diagnosed definitely as colon cancer in the West China Hospital of Sichuan University from Nov. 2007 to Nov. 2008 were studied prospectively, and randomly assigned into the MSCT+SAA group and MSCT group, respectively. Both MSCT and SAA combinative assessment were made for preoperative evaluation in MSCT+SAA group, while only MSCT was made preoperatively in MSCT group. Furthermore, the preoperative staging and prediction of operative procedures were compared with postoperative pathologic staging and practical of operative procedures, respectively.
Results According to the inclusion criteria, 99 colon cancer patients were actually included into MSCT+SAA group (n=49) and MSCT group (n=50). The baseline characteristics of two groups were statistically identical. For MSCT+SAA group, The accuracies of preoperative staging T, N, M and TNM were 81.6%, 79.6%, 100% and 77.6%, respectively. For MSCT group, the corresponding rates were 82.0%, 60.0%, 98.0% and 62.0%, respectively. The difference of accuracies on staging N between two groups was observed statistically (χ2=4.498, P=0.034). There was also a statistically significant difference of the accuracy of prediction of operative procedures in MSCT+SAA group and MSCT group (95.9% vs. 82.0%, χ2=4.854, P=0.028). The preoperative staging N (P=0.008), M (P=0.010), TNM (P=0.009) and level of SAA (P=0.004) were related to the selection of operative procedures when analyzed the relationship between the operative procedures and multiple clinicopathologic factors in colon cancer.
Conclusion The strategy of the combinative assessment of MSCT and SAA could advance the accuracy of preoperative staging, thus serve surgeon the more accurate prediction to surgery strategy in colon cancer.
