What is the best way to proceed in anal cancer surveillance if PET avidity of the primary is reduced, but still avid at time point <6 months s/p chemo-RT?

Patient is 4 months s/p CRT with resolution of avid lymph nodes and no evidence of disease on anoscopy. PET avidity is currently <10 SUV from 30 SUV pre treatment.
