Shelly, if you have decided not to go with surgery, I respect your decision. However, I would still advice you to go for a multi-drug (Taxane + Carboplatin/Cisplatin + 5-FU)chemotherapy instead of pallative care.
Since you did not have any prior chemotherapy, you stand a better chance to have complete recovery or partial recovery to go with further treatment.
Hoping that you will consider my advice and discuss with your medical oncologist.
