There are two tumors that are often mistaken for GISTs and specifically those known as: (1) Fibromatosis; and (2) leomysarcoma. (Rubic, Heinrich, and Corless, 2007) Findings in this study include that there apparently are genetic bases for development of gastrointestinal stromal tumor and that in the Chinese population that when comparing the U.S. And Hong Kong demonstrates that Hong Kong is comparable to the U.S. And lower than Finland. This is likely to be true for the entire Chinese population although this fact could not be confirmed in the present study. Findings in this study additional include the findings that the previous optimal treatment for GISTs is likely not to be the best method of treating this condition and indicating that further and additional research is required toward the necessity and needs of different treatment options that are evidence-based and found to be more effective in treating this condition.
