My husband has recently been diagnosed with stage 4 stomach cancer. It has spread to his lymph nodes and he has one small spot on his liver. 

He is due to begin treatment this month. We received info regarding treatment through the post. He's going to be having capecitabine and oxalaplatin (sorry I probably spelled that second one wrong).

I'm wanting to know what will happen after his 6 cycles of treatment. I have stage 4 breast cancer myself and finished 6 cycles of chemo in October last year and am now on herceptin and perjeta. Will my husband be offered any type of immunotherapy?

I've read on line about a treatment called keytruda but no one has mentioned this to us so I'm wondering if it isnt available. Are there any other options?

We have a small baby and need all the help/advice we can.

Thanks in advance.
