My husband has colon cancer and just finished 28 radiation treatments and four courses of oxiplatin, 5-FU and leukovorin (every 2 weeks), he will be having surgery in about 2 weeks. They gave him these treatments to shrink the tumor which was about 10 cm when discovered.
His tests for the "tumor markers" were all negative and initial CT scan just showed a thickening of the colon wall. It took the doctors quite a while to decide if it was really cancer or not.
Anyhow, after the radiation treatments, his butt looked like an overcooked ham, just almost burned. And the chemo makes him very sick. He threw up for three days continuously after this last one, and that's in spite of the "anti-nausea" two drugs which only helped a little bit. He has a lot of pain, caused in part by his hernia which will also be repaired when they take the tumor out.
The side effects of the cold sensitivity lasts about 2 days after the chemo is taken off. He has a chemo pump that he wears for about 22 hours x 2 days, plus the 4 hour infusion at the cancer treatment center.
One think that amazes me is the great variation in the number and duration of people's treatments.
I talked to one lady who had been diagnosed with stage 4 and had cancer practically everywhere. She was absolutely sold on the chemo, says last exam showed she was nearly cancer free and she feels great.
But another guy, a former police officer, had to discontinue the oxyplatin after a while because the cold sensitivity and numbness began to last longer and longer.
My husband was supposed to have 2 more sessions of chemo (about a month's worth), but after his last treatment, he decided he just couldn't take it anymore. His surgeon says if it was him, he wouldn't take those last two either, says it wouldn't make too much difference. Surgery should remove the tumor, but the surgeon left it very open as to what exactly my husband will wake up with....a few inches of colon removed or a bag. Pretty scary. I wish we knew more.
