I see GA in one of the posts. Are you living in Atlanta? Dr Ballard from Piedmont Cancer Center in Atlanta is working with Dr Kemeny. They are exchanging patients sometimes , cooperate and you can receive some treatments locally, some in NY. They try hard to arrange everything as convenient for patients as possible. I am one of their shared patients.
I personally met 2 of Dr Kemeny patients with peritoneum involvement. One had HIPEC by Dr Sugarbaker , than HAI pump, resection, is NED, no chemo.
The other one had MSKCC version of HIPEC, HAI pump, resection, is NED, now on chemo.
You can successfully treat traditionally (chemo+surgery) some of stage 4 patients with more sites affected. The key is: good response to chemo,(Sarah, Melissa - the CEA of your husband went down fast), aggressive surgeon and oncologist.
