Stage three kidney cancer

Hi everyone, my mum had stage three grade three transitional cell kidney cancer. She had a radical nephrectomy. We had initially been told it was stage one. Although it was grade three, thank god it was still localised. Due to it being a higher stage & grade she has to have three cycles of chemo, GemCarbo. Has anyone had this chemo? Would be nice to know of any side affects. I know everyone is different but we are all very worried. Thanks in advance
