Would you recommend adjuvant chemotherapy for a resected extensive, multifocal gastric pT2(m) pN3 MiNEN arising in a background of autoimmune gastritis?

The tumor spans >17 cm and comprises a G2 NET component involving eight lymph nodes and an adenocarcinoma component that does not extend beyond T2 but has LVI. If so, would you favor fluoropyrimidine monotherapy or FOLFOX for six months?
