How would you mange a completely excised true anal margin squamous cell carcinoma, with anal canal uninvolved, with positive inguinal nodes that were not managed surgically?

Chemo RT to anal margin, anal canal, inguinal and pelvic nodes to 45 Gy/25 fx. Boost positive inguinal nodes to 55.8-59.4 at 1.8 Gy/fx. PET at 3 months. Resect whatever is left (hopefully nothing).
