Stage IV T2N2bM0 squamous cell carcinoma of the left lateral tongue, on IRB 121712 clinical trial, 1 month post TFHX ending 9/16/16. There are post-treatment findings without evidence of measurable mass in the left oral tongue, which measures up to approximately 40 mm. There has been interval decrease in size of the necrotic left cervical lymphadenopathy. In particular, there is a cystic or necrotic left level 2B lymph node measures 25 x 32 mm in axial cross-section, previously 43 x 47 mm. The lymph node tumor appears to slight infiltrate into the adjacent left parotid gland. A left level 1 lymph node measures 5 x 6 mm in axial cross-section, previously 12 x 13 mm. The left lateral retropharyngeal lymph node is asymmetrically prominent and measures 3 x 4 mm in axial cross-section, previously 4 x 8 mm. There is a right level 2A lymph node with a rounded morphology, which measures 7 x 10 mm in axial cross-section, which is not enlarged by size criteria. There is no significant right cervical lymphadenopathy. There is a cystic right thyroid nodule that measures up to 9 mm. There are small maxillary sinus retention cysts. There are also secretions in the left sphenoid sinus. The orbits and imaged intracranial structures are unremarkable. There is a small posterior disc-osteophyte complex at C5-C6 that mildly indents the spinal cord.
