I had surgery last nov and had a t1n1 tumor (2 mm) at the base of my appendix. i finished 12 treatments of folfox. what are my chances of a cure?

Probably good: It is unusual to have spread to a lymph node from such a small tumor. I need more information about the surgical procedure and the type of cancer to give a proper opinion about your prognosis. However, with just 1 node involved, and a proper surgical resection and chemotherapy, your outlook is much better than if 4 or more were involved. Your cure rate could be as high as 75 or 85%. Good luck!
