CC: Right neck swelling HPI: JD is a 63M initially presented to PCP with a painful R neck mass after URI, thought to be neck abscess Saw outside HNS and received antibiotics and needle aspiration showing frank pus Sent to WHC ED and admitted to HNS ROS: Negative

CC: Right neck swelling PMH: HTN PSH: Lithotripsy for left renal calculus, arthroscopy R knee Meds: Atenolol-Chlorthalidone, Aspirin FamHx: Denies Social Hx: Employed as mailman. Never smoked. Occasional EtOH

Physical Exam Gen: NAD, AAOx3 Eyes: EOMI, PERRLA Ant nares: Clear Ears: Clear, TM intact OC/OP: Tonsils symmetric 1+ b/l, tongue mobile, no palpable masses, no erythema Neck: Rightlevels II and III LAD. Salivary glands soft and symmetric b/l.Thyroid normal to palpation. Trachea midline, no masses or tenderness.

Flexible laryngoscopy Nasal mucosa: no signs of inflammation Turbinates: normal morphology Polyps: No polyps or masses Septum: No performations Nasopharynx: No significant adenoid enlargement, eustachian tube orifices clear Oropharynx: Pharyngeal walls normal Hypopharynx: No pooling of secretions; no lesions or erythema Larynx: Vocal cord motion is normal; no lesions Vocal Folds: No vocal fold lesions

Evaluation FNA: no signs of malignancy Taken to OR for LN bx and I&D of neck abscess: 2 large nodes. Frozen positive for metastatic SCCa. DL completed PET/CT: Concordant FDG-PET and CT images with necrotic LAD R neck R MRND: 2/44 R level III nodes with metastatic SCCa Diagnosis: TxN2bM0 SCCa, primary site unknown

Carcinoma of unknown primary WHO definition: histologicdx of malignant neoplasm metastatic to cervical LN without identifiable 1o tumor following comprehensive evaluation SCC: 53-77% of CUP histologies1 Constitutes 2-4% of head and neck SCCa2 Presentation3 Neck mass 94-100% Pain 9% Weight loss 7% Dysphagia 4% M:F = 75% : 25% Mean age 55 1.

Evaluation H&N exam, FFL, CT, FNA, panendoscopy, PET/CT Directed biopsies Only 17 – 63% of primary tumors identified1,2 Failure to find primary3: Small size Cryptic location Tumor regression Most common primary sites identified in workup of CUP are palatine tonsils and BOT4 1.

What if 1o site is not found? Remaining true CUP cases are treated with either primary wide-field radiation or chemoradiation therapy with or without neck dissection 5-year actuarial survival1: 69% for N1 58% for N2 30% for N3 1.

N = 10 CUP patients from the University of Pittsburgh All patients underwent cervical bx, PET/CT, formal endoscopy, bilateral tonsillectomy, random bx BOT When 1o site not found  TORS lingual tonsillectomy 9/10 (90%) with pathologic exam revealing invasive SCCa Mean diameter = 0.9 cm

Multi-institutional study: University of Washington, MD Anderson, University of Alabama-Birmingham, UT-Houston, Johns Hopkins, Oregon Health Sciences N = 47 patients with CUP Tumor siteidentified by TORS in 34 of 47 (72.3%) 18 with no suspicious findings  72.2% identified Suggests that regardless of the preoperative findings, TORS had a consistently high diagnostic rate JAMA Otolaryngol Head Neck Surg. 2013

Conclusions CUP is a devastating diagnosis with previously poor treatment options and prognoses Wide-field radiation therapy causes significant morbidity Finding primary site leads to much better survival outcomes TORS has potential to improve both discovery of primary tumor sites and overall survival in these pts Analysis of quality-of-life studies after TORS has shown minimal disruptions in day-to-day functions
