SPSS and multivariate analysis

Dear Friends,

I needed a help in deciding the right test using SPSS and how to do it please.

I am comparing survival of two different cancers. Rt side colon vs left colon cancers.

I have several variables

for eg: 1) patients who had chemotherapy-yes/no
2) what stage at diagnosis: stage 1,or 2 or 3 or 4
3) When they operated emergency or no emergency

So not sure how to use Cox proportional analysis or multivariate analysis.

Thank you
