Transoral laser surgery for supraglottic cancer

Abstract The goal of treatment for supraglottic cancer is to achieve cure and to preserve laryngeal function. Organ preservation strategies include both endoscopic and open surgical approaches as well as radiation and chemotherapy. The challenge is to select the correct modalities for each patient. Endoscopic procedures should be limited to tumors that can be completely visualized during diagnostic microlaryngoscopy. If complete resection can be achieved, the oncologic results of transoral laser surgery appear to be comparable to those of classic supraglottic laryngectomy. In addition, functional results of transoral laser resection are superior to those of the conventional open approach, in terms of the time required to restore swallowing, tracheotomy rate, incidence of pharyngocutaneous fistulae, and shorter hospital stay. The management of the neck remains of paramount importance, as survival of patients with supraglottic cancer depends more on cervical metastasis than on the primary tumor. Most authors advocate bilateral elective neck dissection. However, in selected cases (T1,T2 clinically negative [N0] lateral supraglottic cancers), ipsilateral selective neck dissection could be performed without compromising survival. The authors conclude that with careful selection of patients, laser supraglottic laryngectomy is a suitable, and often the preferred, treatment option for supraglottic cancer. © 2008 Wiley Periodicals, Inc.

Carcinoma of the Tongue Base Treated by Transoral Laser Microsurgery, Part Two: Persistent, Recurrent and Second Primary Tumors

THE LARYNGOSCOPE, Issue 12 2006
David G. Grant MD
Abstract Objectives: To report the oncologic and functional outcomes of transoral laser microsurgery (TLM) in the treatment of persistent, recurrent, and second primary squamous cell carcinoma of the tongue base. Study Design: A two-center prospective case series analysis. Methods: Twenty-five patients with persistent, recurrent, or second primary squamous cell carcinoma of the tongue base were treated with TLM between 1997 and 2005. Four (16%) patients with persistent disease at the primary site were considered TX. Eleven (44%) patients with recurrent disease were pathologically staged rT1 3/11, rT2 2/11, rT3 4/11, T4 1/11, and TX 1/11. Ten (40%) patients with second primary tumors were staged pT1, 4/10; pT2, 3/10; pT3, 2/10; and pT4, 1/10. Eight (32%) patients underwent neck dissection. Three (12%) patients received adjuvant radiotherapy. Pre- and post-treatment organ function was assessed using a clinical Functional Outcome Swallowing Scale (FOSS) and Communication Scale. Results: The mean follow-up period was 26 months. The 2-year Kaplan-Meier local control and locoregional control estimate was 69%. For those patients presenting with persistent/recurrent or second primary disease, the 2 year local control estimates were 75% and 68%, respectively. For all patients, the respective 2 and 5 year overall survival estimates were 54% and 26%. Two (8%) patients suffered postoperative hemorrhage. The average duration of hospitalization was 3.6 days. The median pretreatment and posttreatment FOSS stage was stage 2 and stage 3, respectively. Conclusions: Transoral laser surgery is a rational and effective treatment in appropriately selected patients with persistent, recurrent, or second primary tongue base cancer. The low morbidity and mortality and shortened duration of hospitalization associated with TLM make it an attractive therapeutic alternative. [source]

Functional outcomes of transoral laser surgery of supraglottic carcinoma compared with a transcervical approach

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2004
Rubén Cabanillas MD
Abstract Background. Several functional advantages have been described for the transoral laser supraglottic laryngectomy as compared with open techniques. However, comparative studies have been rarely performed. Methods. Functional results in 26 patients treated with a transoral approach were retrospectively compared with those of a comparable series of 26 patients who underwent a transcervical approach. Results. The only significant differences found between the two groups were a lesser number of temporary tracheotomies and a shorter time of removal of the nasogastric tube in the laser group. No significant differences were found in the incidence of postoperative complications, hospital stay, and swallowing capacity. Conclusions. The rate of functional problems after transoral laser surgery did not greatly decrease compared with the rate after the conventional procedure. The mayor advantage of the transoral approach was the lower incidence of temporary tracheotomies. © 2004 Wiley Periodicals, Inc. Head Neck26: 653,659, 2004 [source]
