Efficacy of diagnostic upper node evaluation during (salvage) laryngectomy for supraglottic carcinoma

Ronald J. E. Pennings MD
Abstract Background. The effectiveness of selective upper node dissection or inspection during laryngectomy for supraglottic squamous cell carcinoma was evaluated. These diagnostic procedures aimed to cause less morbidity than elective neck dissection in patients with a clinically N0 neck. Methods. In 93 patients, 166 clinically N0 necks (73 bilateral and 20 contralateral) were evaluated. Lymph nodes at levels II and III were inspected or dissected and directly sent in for frozen section histopathology. This way, occult neck metastases were identified and treated by neck dissection. Results. Occult neck metastases were identified in 19% of the examined necks (31/166). Regional recurrence rate in the postoperative N0 necks was 0%, and 10% in the postoperative N+ necks. Conclusions. Selective upper node dissection and inspection during laryngectomy reduced the need for an elective neck dissection with its morbidity in the clinically N0 neck. In addition, it selects the patients who need such extensive treatment. © 2008 Wiley Periodicals, Inc. Head Neck, 2009. [source]

The distribution of lymph node metastases in supraglottic squamous cell carcinoma: Therapeutic implications

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002
Luca O. Redaelli de Zinis MD
Abstract Background. The treatment of the neck in cancer of the upper aerodigestive tract is still a matter of controversy, even though nowadays there is a trend in the literature toward elective surgery in the N0 neck when the probability of occult lymph node metastasis is greater than 20%. In the elective setup, every effort is made for preservation of uninvolved nonlymphatic structures in positive neck. The aim of this study is to analyze in a large cohort of patients treated for supraglottic carcinoma the prevalence of lymph node metastases and their distribution through various neck levels to redefine our policy of neck treatment. Methods. A retrospective review of 402 consecutive patients, who underwent surgery in the Department of Otolaryngology of the University of Brescia (Italy) for supraglottic squamous cell carcinoma in a 14-year period, has been performed. The prevalence of neck metastases was assessed by pT category and site (marginal vs vestibular) of the primary tumor. The side(s) of neck disease was related to the side of the primary tumor, whether lateral or central. The distribution of involved lymph nodes through the neck levels was determined. Results. Overall lymph node metastases accounted for 40%; their prevalence rate increased with pT category from 10% to 57% (p = .0001). Occult metastases were found in 26% of N0 patients from 0% in pT1 to 40% in pT4 (p = .02). There was no difference in metastases rate between marginal vs vestibular, and central vs lateral neoplasms, whereas bilateral metastases were more frequent in central tumors (20% vs 5%; p < .0001). Level IV was involved only in association with level II and/or level III. Levels I and V were rarely involved when overt metastases were present and never by occult metastases. Conclusions. Elective lateral neck dissection (levels II,IV) is recommended in T2,T4 N0 supraglottic cancers; clearance of both sides of the neck is indicated whenever the lesion is not strictly lateral. We still perform a selective neck dissection including levels II,V whenever there is clinical, radiologic, or intraoperative evidence of metastases at any level. © 2002 Wiley Periodicals, Inc.

Voice, Speech, and Swallowing Outcomes in Laser-Treated Laryngeal Cancer,

THE LARYNGOSCOPE, Issue 6 2003
Matthew C. Jepsen MD
Abstract Objective To describe preliminary voice, speech, and swallowing outcomes in patients treated by endoscopic laser excision of laryngeal cancer with or without adjuvant radiation therapy. Study Design Retrospective review. Methods Seventeen surgically treated patients (five T2 glottic and 12 clinically staged T2 supraglottic squamous cell carcinomas) participated in the study. Self-ratings of voice (Voice Handicap Index) and swallowing (M. D. Anderson Dysphagia Inventory) were completed, as well as independent auditory-perceptual ratings of voice and speech recordings. Results Although no significant difference between Voice Handicap Index, M. D. Anderson Dysphagia Inventory, and listener ratings was identified based on tumor site and irradiation status, there was a trend toward poorer outcomes in patients who received adjuvant radiation therapy. Whereas the patients having supraglottic cancer tended to report better voice but poorer swallowing outcomes, the glottic cancer group displayed the opposite pattern. Severity on Voice Handicap Index correlated significantly with listener severity ratings of speech, suggesting that the patients' perception of their voice handicap was similar to the listeners' judgments of their speech severity. Conclusions The results suggest the following trends: 1) Adjuvant radiation therapy was associated with poorer outcomes for voice, speech, and swallowing and may be associated with more impairment than surgery alone and 2) poorer outcomes on voice and swallowing were observed for the glottic and supraglottic cancer groups, respectively. To bolster these preliminary findings, additional outcomes studies in patients treated with conservation therapy are needed. [source]
