Transglottic Extension of Laryngeal Tumor

ABSTRACT Background Using neck ultrasound to evaluate the status of the lymph nodes of a patient with a head and neck cancer is common practice but laryngeal ultrasound could help to receive more information of the tumor. Methods and results We report a case of an initially T1a N0 M0 G2 R0 squamous-cell carcinoma of the right vocal cord. Despite regular follow-up, the relapse of the tumor remained undetected. The hypopharyngoscopy and laryngoscopy were performed. The tumor was evaluated with laryngeal ultrasound and to confirm the relapse of the tumor a MRI scan was performed. Endoscopically there was no obvious presence of the tumor. Laryngeal ultrasound facilitated the visualization of the tumor in good quality. Unfortunately, a total laryngectomy was necessary to treat the relapse of the squamous-cell carcinoma (T4a N0 (0/16) M0 G2 R0). Conclusion Despite careful follow-up via laryngoscopy a relapse of the laryngeal tumor was not visible. Using laryngeal ultrasound, the relapse might have been detected sooner.

Aims: To evaluate diagnostic accuracy of pretreatment surgical magnetic resonance images (MRI) in assessment of patients with tumors of the larynx. Materials and methods: The study included 12 patients, 11 men and 1 women, age 614 years. All patients underwent laryngeal endoscopy and biopsy followed by MRI. The biopsy confirmed that all patient had squamous-cell carcinoma. The MRI images were evaluated for presence in supraglottic, glottic or subglottic region, invasion of submucosal space, cartilage, extension to extralaryngeal tissue, presence of regional lymph nodes in regions I to VII. Imaging data were compared to surgical findings. Results: In 11 patients (92%) the tumor was supraglottic and glotic region and in 1 (8%) subglottic. None of them had tumor only in one region. Paraglottic ivasion was seen in 9 (75%) and preepiglottic in 2 (50%) patients. Paraglottic and preepiglotic invasion in the same time was seen in 3(25%) patients. 7 (58%) patients had normal vocal cord mobility, 3 (25%) mobility was unilateral and 2 (17%) had no vocal cord mobility. Cartilage invasion has not been seen in present study. All patients had billateral limphadenopathy region II-IV. Extension to extralaryngeal tissue was absent. These findings were confirmed on surgery with high diagnostic accuracy. Conclusion: MRI has been shown to be a reliable method for presurgical assessment of patients with tumor of the larynx.
