    I suggest reviewing the following items and making the necessary corrections:

    *Table 1 and 2 are not included in the article although they have been mentioned in the text

    *The degree of positivity used for Ki-67 is not sufficient the value used by Motta et al 2009 might be bettter

    *There is difference between the  patients number mentioned in each group and the T and N data.

    *There are odd numbers of patients mentioned such as 34.637, 4.535, 1.716, and 1.637 patients?!!!!!

    * It is advisable to show the disease free survival rate for both groups instead of just considering survival rate in group A
