Sinonasal Carcinoma and Ohngren's Line: Retrospective Cohort Study of 39 Patients

xlomafota13 shared this article with you from Inoreader Sinonasal Carcinoma and Ohngren's Line: Retrospective Cohort Study of 39 Patients Via Clinical Otolaryngology Abstract Approximately two thirds of this study cohort displayed a sinonasal carcinoma extending across Ohngren's line at diagnosis. Tumor extension across Ohngren's line at diagnosis is a negative prognostic factor for clinical outcome in accordance with AJCC 8th edition. 90% of tumors presenting with retropharyngeal lymph node metastasis were extended across Ohngren's line at diagnosis. The presence of retropharyngeal lymph node metastasis is a strong negative prognosticator for survival in our study. Retropharyngeal lymph node metastasis at diagnosis may be considered for inclusion in tumor staging for sinonasal carcinoma. View on the web Inoreader. Take back control of your news feed.
