colorectal cancer by grade of venous invasion coupled with histological subtype
Version:

Reviewer's report:
The manuscript has been appropriately revised and now it is acceptable to be
published. However, still the quality of images are not good. Changing the dpi
will not increase the quality of figures if the figures are originally low quality
images. I request if possible to change the images with new high quality images.
