There is nothing much new going on with chemo these days. Radiation and chemo are synergistic. This means that in addition to the systemic effect chemo also makes the cancer cells in the radiation field easier to kill.
I have no issues with any organ damage from the chemo to my knowledge. One thing I would recommend if you elect to get chemo. See if you can get the weekly treatment, they make more sense and are better tolerated. I had cisplatin and since I had problems with this we switched to carboplatin. This is another advantage of the smaller weekly dose, you actually have time to change if something is not right for you.
