Incidence and patterns of retropharyngeal lymph node involvement in oropharyngeal carcinoma.

CONCLUSIONS: RP LNs were identified in 10% of oropharyngeal carcinoma patients, and were associated with contralateral neck disease and/or posterior pharyngeal wall/soft palate primary. Contralateral RP LN involvement was rare and associated with contralateral neck disease and/or primary crossing midline, suggesting potential for omission from target volumes for selected patients. Involvement of RP LNs close to the skull base highlights the need for generous elective outlining. PMID: 31431388 [PubMed - as supplied by publisher]
