Summary of new main scinetific contribution of the thesis:
Dividing stages of gastric cancer according to AJCC obtained the following results: overall accuracy: 46.6%, Sn: 30.8 – 62.5%, Sp: 78.3% - 100%, Acc: 70.5% - 87.5%, PPV:36.4% - 100%, NPV: 84.4% - 94.8%.
The following characteristics: tumor length, tumor position, microscopic classification has significant values in the diagnosis at the correct stage of gastric caner on MDCT (The difference is not statistically significant in dianosing stages by MDCT and histologic). But the limitations of MDCT are: Tumor differentiation, invasive tumor, lymph node (LN), stage AJCC and number of metastatic LN / harvested LN (The difference is statistically significant dianosing stages by MDCT and histologic).
Its sensitivity of N and AJCC staging low presents problems when using it to make therapeutic decisions. Improvements in imaging equipment and techniques will be essential in overcoming the drawbacks of this method, and rigorous criteria should be developed to improve the clinical usefulness of MDCT.
