Disease increased after radiation?

So my dad went 25 fractions of radiation (45 Gy) for pelvic radiation and sacral met which he finished on 11 May, 2022. Last PET scan was done in Mar 2022 and the recent PET scan was just done yesterday in (June 2022).
ill defined soft tissue lesion in pelvic cavity (SUVmax 8.54 vs 8.16, 46x43 vs 45x41 mm). It was SUVmax 7.78 pre-radiation and size was 2.3x3.1cm. It also says lesion is inseparable from adjacent bowel loops. Significant perlesional fat and stranding nodularity is seen.
Negligible FDG avid few small subcentimetric reptroperitoneal, abdominal and pelvic lymph nodes are seen. No size significant FDG avid lymphadenopathy in abdominal and pelvic region.
And the sacral lesion has also gone from SUVmax 8.8 to 9.99. It says "intense FDG avid predominantly sclerotic osseous lesion in proximal body of sacrum at S1 vertebra.
Though post radiation(1 month after treatment) CEA has dropped to 1.98 which was about 4.8 (pre-treatment).
Our doc pre-treatment told us that the radiation will just eradicate these mets and if somehow they lived they will get too small then the chemo can finish them off. I have no idea what to do now.
What should be my next step?
