Abstract

Objectives: To identify the differences in sensitivity and accuracy between ultrasound-guided and palpation-guided fine needle aspirations (FNA) of suspicious lymph nodes in patients with human papillomavirus (HPV) (+) oropharyngeal squamous cell carcinoma (OPSCC). Additional objectives included identifying patient specific factors affecting biopsy accuracy and evaluating potential differences in accuracy between fine and core needle biopsies. Study Design: Retrospective chart review. Materials and Methods: A retrospective study of diagnostic sensitivity was completed at a single tertiary care center between 1/1/2006–12/31/2016. Participants included patients who underwent pretreatment FNA biopsy with HPV(+)OPSCC confirmed pathologically following neck dissection or excisional lymph node biopsy. A true positive (TP) on FNA biopsy was defined as an FNA biopsy concerning for squamous cell carcinoma (SCC) that was confirmed on excisional biopsy or neck dissection. A false negative (FN) was defined as a negative FNA but metastatic disease identified on excisional biopsy or neck dissection. Sensitivity was calculated as TPs/(TPs + FNs). Sensitivity was compared among techniques using chi-square and Fisher exact tests. Results: A total of 209 FNA biopsies among 198 patients were included in the study, including 31 (15%) palpation-guided FNAs, 160 (77%) ultrasound-guided FNAs, and 18 (9%) ultrasound-guided FNA + core biopsies. Sensitivity was significantly different among palpation-guided FNA, ultrasound-guided FNA, and ultrasound-guided FNA + core biopsies (48% vs. 83% vs. 94%, respectively; P <.001) but there was no significant difference in sensitivity between ultrasound-guided FNA versus ultrasound-guided FNA + core biopsies (P =.31). Conclusion: The use of ultrasound guidance in FNA biopsies of nodal metastases in HPV(+)OPSCC improves sensitivity compared to palpation guidance alone. Ultrasound guided biopsies are preferred in patients with suspected nodal metastasis from HPV(+)OPSCC. Level of Evidence: 3 Laryngoscope, 2022.
