Pretreatment PET/CT(A) and post-treatment PET/CT(B) in patient harboring oropharyngeal tumor with complete metabolic response at 14th day, cycle 1 of induction chemotherapy (SUV variation from 5.1 to 0.0 and 5.3 to 0.0 in lymph node and primary tumor respectively). Pretreatment PET/CT(C) and post-treatment PET/CT(D) in patient harboring non-responsive oropharyngeal tumor with Increased metabolic response at 14th day, cycle 1 of induction chemotherapy (neck lymph node SUV variation from 2.8 to 3.6, despite achieving a complete metabolic response in primary tumor).
