Ramamurthy --

You indicated that you are T3, but that the tumor was only 2cm in size. If it was truly only 2cmm, you would more likely be T1 or T2. Definitive radiation therapy is possible for smaller tumors. Mine on the base of the tongue was just about 2cm, and they did use definitive RT for the tumor itself without surgery. They did do simultaneous chemotherapy for 8 weeks. Generally, as T stage increases, the less likely it is that definitive radiotherapy can be used in isolation.

I would frankly be more concerned about the metastasis to the lymph node. Even though I had only 1 clinically positive node, and not a very large one, they did a bilateral neck dissection in my case. That is not a difficult surgery, and can make the difference in recurrence in the neck.

Good luck to you!!
