Supracricoid laryngectomies: long-term oncological and functional results

CONCLUSIONS: Our results confirm that supracricoid laryngectomies (SL) are reliable techniques for glottosupraglottic tumors, even for selected T3 and T4 cases, if the indications are correct. These surgical techniques allow a good quality of life with the preservation of the larynx. OBJECTIVE: SL with cricohyoidoepiglottopexy (CHEP) and cricohyoidopexy (CHP) have been popular over the last 20 years for the treatment of the glottic and/or supraglottic squamous cell carcinoma due to demonstrated good oncological and functional results. We report our experience with these techniques, with special focus on long-term oncological and functional results. PATIENTS AND METHODS: We retrospectively reviewed 206 patients who had undergone SL with CHEP or CHP technique between 1987 and 1998 for glottosupraglottic squamous cell carcinoma in our department. The long-term results for 206 patients with T1-T4 laryngeal carcinomas treated with SL are reported: 90.8% CHEP and 9.2% CHP. The mean follow-up was 62 months. RESULTS: Oncological results: the 5-year actuarial disease-free survival was 85%; the 5-year determinate actuarial survival was 88.3%. Functional results: organ preservation rate was 97%. Phonation was assessed according to the GRBAS scale.     

Supracricoid partial laryngectomy with cricohyoidoepiglottopexy and cricohyoidopexy for glottic and supraglottic carcinomas

OBJECTIVES: To review the patients operated in our department with supracricoid partial laryngectomy with either cricohyoidoepiglottopexy (CHEP) (59 cases) or cricohyoidopexy (CHP) (10 cases) technique, for primary or recurrent glottosupraglottic squamous cell carcinoma and compare the technique with other surgical or conservative approaches for treatment of laryngeal carcinoma. METHODS: From hospital charts, we retrospectively reviewed 69 patients who had undergone supracricoid partial laryngectomy with the CHEP or CHP technique between 1983 and 1996 for primary or recurrent glottosupraglottic squamous cell carcinoma in our department. Statistical evaluation of oncological and functional results were conducted. Results were compared with other surgical and conservative treatment for glottosupraglottic carcinoma of the larynx that were published previously in the literature. RESULTS: Sixty-nine patients had CHEP or CHP for glottosupraglottic carcinoma of the larynx. Thirteen percent of the patients received adjuvant radiotherapy. Minimum follow-up was 2 years or until death. Five-year actuarial survival (Kaplan-Meier method) was 68%. Global local control was achieved in 84% of cases. Among previously untreated patients (n = 54), local control rate was 94.5%. After 1 year, 92.7% of patients achieved normal swallowing and respiration. Salvage total laryngectomy had to be performed in four patients (5.7%) for persistent aspiration and in five patients (7.2%), who were previously treated with radiotherapy, for local recurrence. No permanent tracheostomy or gastrostomy was required. CONCLUSIONS: Our experience with supracricoid partial laryngectomy with either CHP or CHEP suggests that this technique is a valuable alternative to radiotherapy for T2-T4 glottosupraglottic carcinomas, particularly those with extension and invasion of the anterior commissure. It allows for preservation of a good laryngeal function without altering the long-term survival, keeping total laryngectomy as a salvage procedure.     

Supracricoid partial laryngectomy with cricohyoidopexy and cricohyoidoepiglottopexy: functional and oncological results

Sixty-eight patients who presented with glottic and glottosupraglottic squamous cell carcinoma and who were managed in this department with supracricoid partial laryngectomy (SCPL) with either cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP), were retrospectively reviewed. The authors analysed the functional and oncological results of the patients. The median follow-up period was 62 months. The average times until decannulation and nasogastric feeding tube removal were 27.7 and 26.4 days, respectively. All patients were successfully decannulated. All patients were able to swallow, but one patient was unable to swallow and had recurrent aspiration. Better functional results were achieved in patients managed with CHEP procedure than the patients managed with CHP procedure. The five-year absolute and cause-specific actuarial survival rates (Kaplan-Meier method) were 78.6 per cent and 93.9 per cent, respectively. The five-year actuarial local control and nodal control rates were 89.5 per cent and 90.4 per cent, respectively. Local recurrence was statistically more likely in patients with positive resection margins (p <0.006). Overall, local control and laryngeal preservation were achieved in 95.6 per cent and 89.7 per cent, respectively. Supracricoid partial laryngectomy procedures (CHEP and CHP) are possible alternatives to total laryngectomy in the treatment of selected advanced glottic and glottosupraglottic carcinomas.     

Supraglottic laryngectomy: analysis of 267 cases

Horizontal supraglottic laryngectomy (HSL) allows the preservation of a functioning larynx and avoids permanent tracheotomy. In this retrospective study we report our experience with HSL and describe the functional and oncological results of the procedure. A total of 267 previously untreated patients with squamous cell carcinoma of the supraglottis underwent a supraglottic laryngectomy at our Department from January 1978 to May 2002. The main outcome measures were: local and regional control, disease-specific survival and laryngeal preservation rate. The overall recurrence rate was 29% (78/267). The local recurrence rate was 8% (22 patients) and the regional recurrence rate was 17% (45 patients). The 5-year disease-specific survival rate was 73%. The 5-year laryngeal preservation rate was 82%. Multivariate analysis showed two parameters that were independent predictors of a reduced disease specific survival: cervical lymph node metastases of class N3 (P = 0.0003) and primary tumour classified as T4 (P = 0.004). HSL provided, in our experience, an optimal locoregional oncological control for laryngeal preservation.     

Successful 10-year outcomes after supracricoid partial laryngectomy for selected glottic squamous cell carcinoma classified as T3N0M0: A STROBE analysis

PurposeTo evaluate long-term oncological outcome for patients with selected glottic squamous cell carcinoma (SCC) classified as T3N0M0 treated by supracricoid partial laryngectomy (SCPL).Materials and methodsAnalysis of an inception cohort of 46 patients with isolated untreated SCC classified as T3N0M0 and minimum 10-year follow-up, consecutively treated by SCPL between 1982 and 2012 in a French university teaching hospital. The main endpoint was 5- and 10-year actuarial survival and local control estimates. Accessory endpoints comprised cause of death, screening for variables decreasing survival and increasing risk of local recurrence, oncologic consequences of local recurrence, and laryngeal preservation rate.ResultsFive- and 10-year actuarial survival was 78.1%, and 53.3%, respectively. The main causes of death were intercurrent disease and metachronous second primary, each in 33.3% of cases. Postoperative mortality (aspiration pneumonia) was 2.1%. There were no significant correlations between survival and any study variables. Five- and 10-year local control was 90.5%. Overall local recurrence varied significantly (P = 0.003), from 2.3% with negative margins (R0) to 100% with positive margins (R1) and/or dysplasia. Local recurrence was associated with a significantly (P < 0.005) increased risk of nodal failure and distant metastasis, and reduced survival. Overall laryngeal preservation was 89.1%.ConclusionThe present results suggest that SCPL should continue to be taught and that this type of partial laryngeal surgery should be included in the various organ-sparing strategies considered in advanced laryngeal cancer.     

Subtotal laryngectomy with cricohyoidopexy as first treatment procedure for supraglottic carcinoma: Institut Gustave-Roussy experience (146 cases, 1974–1997)

Patients and methods: Between 1974 and 1997, 297 patients underwent a subtotal laryngectomy at the Institut Gustave-Roussy; 146 of these patients underwent cricohyoidopexy (CHP) for a supraglottic primary as their first treatment. The majority of patients were men (137) aged from 33 to 78 years (median 54 years). The tumour stage at presentation was T1 in 2, T2 in 87, T3 in 53 (pre-epiglottic space involvement), and T4 (minimal thyroid cartilage invasion) in 4 patients. One hundred and twenty-five patients were N0 (86%) and 21 patients were Np (palpable); 98% had homolateral and 55% had bilateral neck dissections. Results: One patient died postoperatively of a myocardial infarction and 68% patients had an uneventful course. Aspiration was the commonest complication (23 patients, 19%). The median time to removal of the tracheotomy cannula was 10 days and for the nasogastric tube 21 days during the past 10 years. Completion of subtotal laryngectomy into total laryngectomy was done in 21 cases (15%): eight times because of oncological events [five local failures, two second primary (hypopharynx), one positive margin] and 13 times because of aspiration (9%). There were six local failures (4%) and eight nodal failures (5%). The rates of distant metastases and second primaries were 6% and 16% respectively. Half of the local and nodal failures were subsequently sterilized. Findings at death were two local recurrences, four nodal recurrences, eight distant metastases, and 11 second primaries. The 3- and 5-year overall survival rates were 92% and 88% respectively, with an overall laryngeal preservation rate of 86%. Conclusion: When supraglottic laryngectomy is not feasible for supraglottic cancer, subtotal laryngectomy with CHP is a safe and effective oncological procedure, with preservation of satisfactory laryngeal function.

Oncological and functional outcome of conservative surgery for primary supraglottic cancer

The aim of this study was to verify the oncological and functional outcome of conservative surgical treatment of primary supraglottic squamous cell carcinoma (SGSCC) and related neck disease in order to verify the effectiveness of supraglottic laryngectomy (SL) and the validity of an “observation” policy in the control of clinically negative (N0) necks. Of a total of 252 consecutive patients affected by primary SGSCC seen between 1975 and 1990 at the Department of Otolaryngology of the University of Perugia (1975–1987) and the Catholic University of the Sacred Heart of Rome (1988–1990), a subset of 132 patients treated with classical SL was evaluated after presenting sufficient clinicopathological data and a follow-up period of at least 5 years. Tumors were staged according to the 1992 UICC TNM classification and grouped into stages I-II (n = 94) and III-IV (n = 38). Comprehensive neck dissections were performed only in the clinically positive (N+) necks (25/132 cases), while in the clinically N0 ones (107/132 cases) an “observation” policy under strict follow-up conditions was adopted. After primary surgery, the 5-year relapse-free survival (RFS) was 74%. The RFS was 80% for T1-2 disease and 65% for T3. The RFS was 80% for stages I-II tumors and 71% for stages III-IV. The actual 5-year overall survival (OS) was 89% for T1-T2 tumors and 67% for T3 disease or 93% for stages I-II and 69% for stages III-IV. The OS was 89% for N0 neck and 73% for N+. The 5-year-metastasis-free survival (MFS) was 83% for N0 patients, 74% for N+, 84% for T1-T2 N0, 71% for T1-T2 N+, 81% for T3 N0 and 68% for T3 N+. In all, SL was found to be highly effective in the management of primary SGSCC. In the presence of clinically N0 neck “observation” under strict follow-up with therapeutic comprehensive neck dissection for delayed nodal recurrence, SL was suitable for controlling the neck cancer, as well as for salvaging recurrent disease. Bilateral elective, selective or functional neck dissection in every instance of supraglottic cancer was best performed only in those SGSCC patients who were more likely to have occult nodal disease on the basis of biological factors and imaging data.

Supracricoid partial laryngectomy with cricohyoidoepiglottopexy for “early” glottic carcinoma classified as T1-T2N0 invading the anterior commissure

Purpose: “Early” glottic squamous cell carcinoma classified as T1-T2N0 with anterior commissure invasion is conventionnaly managed with vertical partial laryngectomy (VPL) or radiation therapy (FIT). At our institution, in the early 1980s, vertical partial laryngectomy was progressively replaced by supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCPL-CHEP). The medical files and operative charts of 62 patients with “early” glottic carcinoma classified as T1-T2N0 invading the anterior commissure, consecutively managed with cricohyoidoepiglottopexy, were retrospectively reviewed to ascertain whether any conclusions could be drawn regarding this treatment modality.Materials and Methods: Survival, local control, nodal recurrence, distant metastasis, and metachronous second primary tumor estimate was analyzed using the Kaplan-Meier life table method.Results: The 3- and 5-year actuarial survival estimate was 93.3% and 86.5%, respectively. The 3- and 5-year actuarial local control estimate was 98.2%. The only patient with local recurrence was successfully salvaged with FIT resulting in an overall 100% local control rate and laryngeal preservation rate. The 3- and 5-year actuarial nodal recurrence estimate was 1.8%. The 3- and 5-year actuarial distant metastasis estimate was 0% and 2%, respectively. Aspiration related completion total laryngectomy and permanent tracheostomy never occurred.Conclusion: The present retrospective study suggests that cricohyoidoepiglottopexy for glottic carcinoma classified as T1-T2 invading the anterior commissure resulted in higher local control rates and overall laryngeal preservation rate when compared with historical series using either VPL or RT. Further series are warranted to confirm our results.     

Cricohyoidopexy (CHP) and Cricohyoidoepiglottopexy (CHEP). Indication,complications, functional und oncological results

BACKGROUND: Subtotal laryngectomy with Cricohyoido(epiglotto)pexy (CHEP and CHP) is a commonly used surgical procedure in France, Italy and North America, but it is rarely carried out in Germany,where most laryngeal carcinomas staged T1-T3 are resected endoscopically or with total laryngectomy. OBJECTIVE: To identify indications for the CHEP and CHP in a setting that uses endolaryngeal procedures as a standard approach to organ preserving surgery in laryngeal cancer patients. PATIENTS: Nineteen patients with primary (n=15) or recurrent (n=4), supra- or transglottic carcinoma or carcinoma of the anterior commissure staged (r)T1b-4N0-2cM0 were treated with subtotal laryngectomy with CHEP (with or without neck dissection/radiotherapy) between October 1997 and June 1999. RESULTS: Undisturbed deglutition without aspiration and respiration without tracheotomy was achieved in 17/19 patients.Three patients showed temporary pneumonia from aspiration and two patients needed further treatment for endolaryngeal synechia. Three patients died of unrelated causes. Four patients were diagnosed with local recurrence: Two of them died from tumor, two patients had curative total laryngectomy as salvage surgery.Fourteen patients are living free of disease 24-40 months after therapy. CONCLUSION: CHEP is a subtotal laryngectomy with increased postoperative morbidity, but good functional results.Assuming a scrupulous indication for the extended tumors the oncological results of the CHEP are satisfying, too.     

Supracricoid laryngectomy with cricohyoidoepiglotto-pexy or cricohyoido-pexy: experience on 32 patients

OBJECTIVE: Supracricoid laryngectomy (SCL) with Cricohyoidoepiglotto-pexy (CHEP) or Cricohyoido-pexy (CHP) is an organ preservation surgery indicated for early and selected advanced laryngeal cancers. To verify the clinical usefulness of supracricoid laryngectomy versus total laryngectomy, a retrospective review was conducted. METHODS: We summarized the clinical and postoperative data of 32 patients who received SCL over the past 9 years (1997-2005). Five-year survival rate of the SCL patient group (29 cases) was compared with that of the patient group receiving total laryngectomy (35 cases) within the same period. RESULTS: Wound infection was detected in 12 patients (38%). Those with severe infection, which required surgical intervention, included two cases of ruptured pexis and two cases showing cricoid cartilage necrosis induced by Forestier disease. There were two T4 cases that resulted in extensive excision. In one case, excision involved the posterior part of the cricoid cartilage resulting in insufficient closure of the neoglottis; the patient received total laryngectomy 30 months after SCL-CHEP because of persistent aspiration of liquid diet. In the other T4 case, the tumor invaded the thyroid and arytenoid cartilages but not the cricoid cartilage. Reposition of the remaining corniculate cartilage resulted in sufficient closure of the neoglottis; this patient subsequently acquired satisfactory laryngeal function. The 5-year overall survival rate was 86% for SCL group and 61% for the total laryngectomy group (limited to Stages III and IV glottic cancers). The causes of the four deaths were distant metastasis, neck metastasis, and intercurrent disease, respectively. Two patients are alive with distant disease. CONCLUSION: Through our experience in this series, the functional and oncological results of SCL showed certain advantages over those of total laryngectomy. Particularly, the clinical impact of SCL-CHEP was impressive; this technique needs is recommended to both head and neck surgeons and patients.     

Supracricoid hemilaryngopharyngectomy in patients with invasive squamous cell carcinoma of the pyriform sinus. Part II: Incidence and consequences of local recurrence

Supracricoid hemilaryngopharyngectomy (SCHLP) was performed in 147 patients over a 19-year period for previously untreated invasive squamous cell carcinoma of the pyriform sinus. With a minimum of 3 years' follow-up, the current retrospective series was designed to document the incidence, risk factors, and consequences of local recurrence following SCHLP. Before operation, 97.4% of patients had an induction chemotherapy regimen. A complete clinical response and a complete histologic regression were noted in 21.7% and 16.8% of patients, respectively. A significant statistical relationship (p = .0001) was noted between complete clinical response and complete histologic regression. Postoperative radiotherapy was used in 49.8% of patients. The overall local recurrence rate was 8.2%. The 5-year actuarial (Kaplan-Meier life-table method) local control estimate was 90.4%. As a function of T stage, the 5-year actuarial local control estimates were 96.2%, 91.1%, 92.9%, and 62.6% in patients with tumors classified as T1, T2, T3, and T4a, respectively. On univariate analysis, the overall local recurrence rate varied significantly, from 5.3% to 55.6% if the apex of the pyriform sinus was invaded (p = .02), 6.9% to 18.7% if the posterior pharyngeal wall was invaded (p = .03), and 6.3% to 60% if the margins of resection were positive (p = .02). In a stepwise regression model, positive margins of resection (odds ratio, 8.4; 95% confidence interval, 2.2 to 32.2; p = .002) and invasion of the apex of the pyriform sinus (odds ratio, 6.1; 95% confidence interval, 1.1 to 33.3; p = .04) were the variables statistically associated with an increased risk of local recurrence. Local recurrence resulted in a statistically significant increased risk of nodal recurrence (p = .005) and death (p < .004). The overall laryngeal preservation rate was 91.2%. From an oncological perspective, these results suggest that SCHLP should become a major tool in the armamentarium of the head and neck surgeon and should be integrated into future trials aimed at organ preservation in patients with invasive squamous cell carcinoma of the pyriform sinus.     

Oncologic outcomes of transoral laser microsurgery versus open partial laryngectomies in the management of early stage glottic carcinoma

BackgroundThe oncologic outcomes between transoral laser microsurgery (TLM) and open partial laryngectomy (OPL) using comprehensive analysis in one clinical center is rare. The purpose of this study was to evaluate the oncologic outcomes of TLM in patients with early stage glottic carcinoma, and to compare the results with OPL.Subjects and methodsRecords of 425 glottic carcinoma patients with T1 - T2 stage treated with TLM, vertical partial laryngectomy (VPL), and cricohyoidoepiglottopexy (CHEP) from 2005 to 2010 were retrospectively analyzed. The overall survival (OS), disease-specific survival (DSS), and laryngeal function preservation (LFP) of these three treatments were assessed.ResultsOne hundred and twenty-two patients were treated with TLM. Regarding OPL, 167 patients underwent VPL, and 136 patients underwent CHEP. The mean age was 59.7 years, with men accounting for 97.2 % of all cases. The OS, DSS, and LFP rates of patients with anterior commissure (AC) involvement undergoing TLM were worse than those of patients without AC involvement, but these differences were not statistically significant. The 5-year OS, DSS, and LFP of patients undergoing TLM were 88.4 %, 89.9 %, and 83.5 %, respectively, and the oncologic outcomes of patients undergoing TLM, VPL, and CHEP were not statistically different.ConclusionGlottic carcinoma patients with early stage treated with TLM experience satisfactory oncologic outcomes. No compelling difference in oncologic outcomes among three treatments of TLM, VPL and CHEP, as well as VPL and CHEP can be alternatives to patients who are not suitable for receiving TLM.     

CO<Subscript>2</Subscript> laser treatment of laryngeal stenoses after reconstructive laryngectomies with cricohyoidopexy,cricohyoidoepiglottopexy or tracheohyoidoepiglottopexy

Supracricoid laryngectomy with cricohyoidopexy (CHP) or cricohyoidoepiglottopexy (CHEP) is a conservative laryngeal surgery tailored to T1b-T2-T3 glottic-supraglottic carcinomas. Tracheohyoidopexy (THP) and tracheohyoidoepiglottopexy (THEP) allow a chance of conservative surgery also for selected transglottic carcinomas. These techniques are comprehensively named reconstructive laryngectomies (RLs). Post RL laryngeal stenosis not due to carcinoma persistence or recurrence is an unusual occurrence. The aim of the present study has been to analyse retrospectively and describe the treatment of the cases of laryngeal stenosis after RL, which occurred in Vittorio Veneto Otolaryngological Department in a 6 year period. In the period between 1999 and 2004, 225 patients underwent RL in our Department. In 18 of them (8%) a laryngeal stenosis after RL was diagnosed. The same evidence was shown in 2 patients who underwent RL in other Institutions. All patients underwent CO₂ laser surgical treatment of the laryngeal stenosis. The 14 patients who underwent RL-CHEP, the 5 patients who underwent THEP and the patient who underwent CHP were treated on average with CO₂ laser 1.2 (range 1–2), 4.2 (range 2–7), and 2 times, respectively. Decannulation was possible in all patients but one after CO₂ laser treatment of the stenosis in a mean period of 3.4 months. Laryngeal stenoses after RLs can be successfully treated with CO₂ laser excision with a very limited morbility. The only reasonable contra-indication to CO₂ laser excision could be a cranio-caudal length of the laryngeal stenotic tract longer than 1 cm: in this occurrence diagnosed after THP or THEP, an external surgical approach could be preferred.     

Results of surgical treatment alone for primary subglottic carcinoma

Primary subglottic carcinoma is rare and surgery is the most common therapeutic strategy for Chinese patients with this disease. To retrospectively evaluate surgically treated primary subglottic carcinoma treated with surgery. Patients with primary subglottic carcinoma who initially underwent surgery from 2005-2010 were grouped by surgical procedures with or without laryngeal function preservation and reviewed. Of 1815 patients with laryngeal cancer, 23 had a subglottic origin. Of these, 21 initially underwent surgery; 12 had ‘early’ (stage I/II) disease, and nine had ‘advanced’ (stage III/IV) disease. The actuarial 5-year OS was 73.9% [95% confidence interval (54.1% ～ 93.7%)] for patients with squamous cell carcinoma. Among patients with early disease, the 5-year OS and DFS were 80% for partial laryngectomy and 71.4% for total laryngectomy. Patients with advanced disease underwent total laryngectomy, and the 5-year OS and DFS were 62.5%. Satisfactory oncologic outcomes can be achieved with initial surgery. Patients with early disease who underwent partial laryngectomy had a comparable prognosis to those who underwent total laryngectomy; deglutition and speech function were maintained.     

Supracricoid laryngectomy outcomes: The Johns Hopkins experience

OBJECTIVE: To report the oncologic and functional results from our experience in performing supracricoid laryngectomy (SCL) for selected patients with laryngeal cancer. STUDY DESIGN: Retrospective chart review. METHODS: Twenty-four consecutive patients who underwent SCL for laryngeal cancer in our institution from December 2000 to March 2006 have been reviewed. Reports of the site and extent of tumor, type of reconstruction, preoperative or postoperative radiotherapy, and the final histopathologic examination were reviewed. In addition, the reports of the preoperative examination, inpatient course, and postoperative follow-up were reviewed. RESULTS: A total of 24 patients were involved in the study; 19 had tumors involving the glottic region, and 5 patients had tumors involving both the glottic and supraglottic regions (transglottic). Ten patients had their SCL for postradiotherapy recurrence/persistence of disease. Eighteen patients underwent reconstruction through cricohyoidoepiglottopexy (CHEP), whereas six patients had cricohyoidopexy (CHP). Eleven patients had an arytenoid cartilage resected; 8 of 11 had CHEP, and 3 of 11 had CHP. All patients had a tracheostomy and percutaneous endoscopic gastrostomy (PEG) tube placement performed at the same time as the SCL. The median hospital stay period was 6 days. Twenty-three of 24 had successful tracheostomy tube decannulation, with a median time to decannulation of 37 days. The median time to removal of the PEG tube was 70 days. The complications with SCL were postoperative wound infection in two patients (SCL/CHP) and the need for completion total laryngectomy secondary to intractable aspiration in one patient with SCL/CHP. One patient with SCL/CHEP had a ruptured pexy and subsequently underwent a second reconstruction with successful tracheostomy and PEG tube removal. One of 24 patients is still PEG tube dependant, and he had postoperative radiotherapy. Fifteen patients underwent concurrent neck dissection. None of the patients had any local or regional recurrence, with a median follow-up period of 3 years. All final surgical margins were negative for tumor invasion. Three patients had postoperative radiotherapy, two patients because of nodal metastases in the excised lymph nodes and one because of perineural invasion on final histopathologic examination of the SCL specimen. There were no perioperative deaths. CONCLUSION: SCL with CHEP or CHP represents an effective technique that can be taught and effectively used to avoid a total laryngectomy while maintaining physiologic speech and swallowing in selected patients with advanced stage primary laryngeal cancer or recurrent/persistent laryngeal cancer after radiotherapy. There is a good functional recovery with acceptable morbidity and an excellent oncologic outcome when strict selection criteria are applied and a formal swallowing rehabilitation program is followed.     

Oncological outcomes of early stage glottic squamous cell carcinoma treated with transoral laser microsurgery

Materials and methodsThe records of patients treated with TLM with previously untreated early stage glottic squamous cell carcinoma were reviewed.ResultsA total of 201 patients were enrolled: 191 men (95.0%) and 10 women (4.98%). The anterior commissure (AC) was involved in 94 (47.8%) patients. The 3- and 5-year overall survival rates of all patients were 94.5% and 90.9%. The local recurrence rates were 30.8% in the AC involvement (AC+) group and 16.0% in the group without AC involvement (AC–). The mortality rates were 18.1% and 3.7% in the AC+ and AC– groups. The 3- and 5-year disease-free survival rates were lower in the AC+ group (89.1%, 82.5%) than that in AC– group (99.0%, 96.5%). Local recurrence rates were 25%, 22.7%, 23.4%, and 22.1% for Tis, T1a, T1b, and T2 lesions. The mortality rates were 0.0%, 4.6%, 12.8%, and 15.3%. Three- and 5-year disease-free survival rates did not differ significantly between the tumor stage subgroups. The mortality for patients with local recurrence was 22.2%, which was higher than that for those without recurrence. The organ preservation rate was 98.5%.PurposeThis study was to assess the rates of oncological outcomes in patients with early stage glottic squamous cell carcinoma treated with transoral laser microsurgery (TLM).ConclusionAC involvement was a predictor of local recurrence, and its presence was associated with a reduced survival rate and increased mortality after TLM. TLM got high survival rate and low recurrence rate. The staging and oncological outcomes did not differ between tumor stage subgroups.     

Long-term clinical outcomes of supracricoid partial laryngectomy with cricohyoidoepiglottopexy for glottic carcinoma

Abstract

Background: Laryngeal carcinoma should be treated with the intent of organ-sparing, and supracricoid partial laryngectomy with cricohyoidoepiglottopexy (CHEP) might be an important option.

Aims/objectives: The purpose of this study was to evaluate the clinical outcomes of glottic carcinoma patients treated with CHEP.

Materials and methods: A series of 164 cases with glottic carcinoma undergoing CHEP from 2006 to 2010 was retrospectively analyzed.

Results: The 10-year overall survival (OS) rate, disease-specific survival (DSS) rate, and disease-free survival (DFS) rate were 77.6%, 78.8%, 74.1%, respectively. The OS, DSS, and DFS of patients with stage T1 were higher than patients with stages T2 and T3. Patients with locoregional recurrence and distant metastases had lower OS and DFS than patients with neither recurrence nor metastasis. The DFS of patients with advanced laryngeal carcinoma was worse than that of patients with early-stage carcinoma. T2 and T3 stages, locoregional recurrence, and distant metastases had predictive value regarding patient survival. Additionally, the decannulation rate of postoperative patients was 95.1%, and the nasogastric feeding tube removal rate was 100%.

Conclusions and Significance: CHEP provided reliable oncologic and functional outcomes, and it should be considered as a standard function-sparing option for glottic T1b, T2, and selected T3 carcinoma patients.     

Supracricoid partial laryngectomies after failure of radiation therapy

BACKGROUND: Conservation of laryngeal function is a key surgical objective in cases of limited recurrence after previously irradiated T1b or T2 glottic carcinoma. Only a few articles have mentioned the use of supracricoid partial laryngectomies (SCPL) to treat recurrent T1/T2 tumors that cannot be managed with vertical partial laryngectomy. OBJECTIVES: To evaluate oncologic and functional results of SCPL in selected cases of T1/T2 glottic carcinoma recurrence after primary irradiation therapy. METHOD: Between 1986 and 2000, 23 selected patients (T1b, 12 cases; T2, 11 cases) underwent SCPL as salvage treatment: cricohyoidepiglottopexy (CHEP) in 18 cases and cricohyodopexy (CHP) in 5 cases. RESULTS: The mean cannulation time was 28 (14-90) days. The mean nasogastric feeding tube time for CHP and CHEP was 55 (28-96) days and 21 (9-45) days, respectively. Four (17.4%) patients had major swallowing recovery problems. Three patients died in the postoperative period, one of intercurrent disease and two because of aspiration pneumonia. Six (26.08%) patients relapsed and underwent total laryngectomy. Three were subsequently controlled. The T stage was correlated with the onset of a new recurrence (P = .0258). The surgical margins were not correlated with recurrence (P = .0741). At 3 and 5 years, the global survival rate was 82.9% and 69.04%. The success rate for oncologic control and oncologic control with organ preservation was 74% and 66.6%, respectively. CONCLUSION: In selected cases of limited recurrence after radiation therapy for T1/T2 vocal cord carcinomas, SCPL can be an alternative to total laryngectomy when partial vertical surgery appears unsuitable.     

Transoral laser surgery for early glottic carcinoma

This prospective study evaluates the oncological results of transoral laser surgery (TLS) for glottic carcinoma categorized Tis, T1 and T2 in a large, unselected group of 285 consecutive patients from a university-based referral center that uses transoral laser surgery as the standard approach to these tumors. Patients were treated between 1 January 1987 and 31 December 1996. Thirty-three patients had Tis disease, 174 T1 tumors and 113 T2. Main outcome measures were local control with initial therapy, ultimate local control, regional control, organ preservation, overall survival and cause-specific survival. The 5-year uncorrected actuarial survival for all 285 patients was 71.1%, and cause-specific actuarial survival was 98.7%. Local control with initial treatment was 85.9%, ultimate local control with salvage for local treatment failures 98.5%, and regional control 98.4%. In all, 94.3% had their larynges preserved after 5 years. Although favorable oncological results for early laryngeal carcinoma treated with laser surgery are supported this study, no definitive recommendations can be given for the best single treatment. Partial laryngectomies lead to the highest local control rates reported so far, radiotherapy is believed to preserve voice best and laser surgery is associated with time- and cost-effectiveness, low morbidity, fair local control rates and excellent re-treatment options in case of local failure. All specialists dealing with the treatment of early glottic carcinoma should be able to offer these different treatment modalities to their patients and to deal specifically with each patient’s individual needs and preferences.

Analysis of local recurrence in patients with selected T1-3N0M0 squamous cell carcinoma of the true vocal cord managed with a platinum-based chemotherapy-alone regimen for cure

Based on an inception cohort of 35 patients with T1-3N0M0 squamous cell carcinoma of the true vocal cord who had a complete clinical response after a platinum-based induction chemotherapy regimen and a minimum of 3 years of follow-up, the current retrospective study documented the long-term results and consequences of local recurrence following the use of a platinum-based chemotherapy-alone regimen for cure. During the years 1985 to 1996, 231 patients with invasive squamous cell carcinoma of the true vocal cord classified as T1-3N0M0 were managed at our department with a platinum-based induction chemotherapy regimen. A complete clinical response was achieved in 77 patients. Thirty-five of the 77 patients with complete clinical response were managed at our institution with a platinum-based chemotherapy-alone regimen. The statistical analysis of data on survival, local control, nodal control, distant metastasis, and metachronous second primary tumor incidence was based on the Kaplan-Meier product limit method. Univariate analysis was performed for potential statistical relation between local recurrence and various variables. The 3- and 5-year actuarial survival estimates were 91.4% and 88.6%, respectively. Overall, the causes of death were intercurrent disease in 6 patients and metachronous second primary tumor in 4 patients. The 3- and 5-year actuarial local control estimate was 64.8%. No significant statistical relation could be demonstrated between the incidence for local recurrence and the variables under analysis. Salvage treatment in patients with local recurrence yielded a 100% local control rate and laryngeal preservation rate. The 3- and 5-year actuarial lymph node control estimate was 97.1%. The 3- and 5-year actuarial estimate for patients with distant metastasis was 0%. The 5- and 10-year actuarial estimates for patients with metachronous second primary tumor were 9.7% and 28.1%, respectively. Although local recurrence was noted in almost a third of patients with complete clinical response who were managed with a platinum-based chemotherapy-alone regimen, it did not appear to be detrimental, as none of the patients who had local recurrence ultimately died from their disease or lost their larynx.
