A member asked:
Stage iii-b colon cancer removed surgically. suspected liver lesion resected and analyzed with not malignancy. is kras analysis needed for recurrence?

Possibly: For initial treatment after surgery, you shouldn't need to get kras testing. However, if this is metastatic or recurrent colon cancer, then it may help to determine if egfr based therapies like Cetuximab can help (they only work for kras "wild type"). Remember that if you do recur (god forbid), management may be different at that future time! not something to worry about with your current story.

Recommended: Your medical oncologist will be able to counsel you better but determining the kras status could be useful in the future. It might not be necessary, but in the event of resistant disease that requires 2nd and/ or 3rd line treatment, it might help your oncologist make a decision to the appropriate next step. And it may be used for academic or research purposes.
