Role of supracricoid partial laryngectomy with cricohyoidoepiglottopexy in glottic carcinoma with anterior commissure involvement

ObjectivesTo analyze oncologic and functional outcomes after supracricoid laryngectomy with cricohyoidoepiglottopexy (SCL-CHEP) in glottic carcinoma with anterior commissure (AC) involvement, to determine predictive factors, and to compare results with those reported for other therapeutic strategies.Material and methodsA retrospective analysis included all patients who underwent SCL-CHEP for glottic squamous cell carcinoma with anterior commissure involvement in our institution, between 2000 and 2014. Swallowing function was evaluated on the DOSS (Dysphagia Outcomes and Severity Scale).ResultsFifty-three patients were included. Three-year overall, cause-specific and recurrence-free survival rates were 86, 95 and 80%, respectively. There were 5 cases of local recurrence (9%), all treated by total laryngectomy. Smoking was the only predictive factor of recurrence-free survival (P = 0.02). Mean DOSS score was 5.5 ± 0.9. DOSS scores ≥ 6 (normal oral feeding) were recovered by 59% of patients. T-stage ≥ 2 was the only predictive factor for DOSS score (P = 0.04).ConclusionIn glottic carcinoma with anterior commissure involvement, SCL with CHEP provided a local control rate of more than 90%, which is higher than reported with endoscopic surgery or external radiotherapy. However, contrary to LSC, salvage of local recurrence can often be obtained by conservative treatments after endoscopic surgery. Therefore, total-laryngectomy-free survival rates after SCL-CHEP and endoscopic surgery are finally comparable.     

Inverted epiglottis: A postoperative complication of supracricoid laryngectomy with cricohyoidoepiglottopexy

Objectives

Among the 50 laryngeal cancer patients who received SCL-CHEP between 1997 and 2008, we experienced three patients with complete epiglottis prolapse, which obstructed the neoglottis. By defining this complication as “Inverted epiglottis” and presenting the clinical features, we intend to elucidate the mechanism, risk factors, and management of this complication.

Methods

Details of the clinical features are presented. We conducted the following analyses: (1) distance from anterior commissure to the upper resected end of the surgical specimen was grossly measured. (2) Based on the analysis of sagittal cut CT images, the level of vallecula was identified and compared with the level of hyoid bone. (3) Distance between hyoid bone and cricoid arch (cricohyoid gap) after SCL-CHEP was measured using sagittal cut CT images.

Results

Prolonged edema of the neoglottis and delayed stomal closure were the main symptoms. In patients with the vallecula lower than the hyoid bone, excessive resection of the epiglottic petiole (anterior commissure–upper edge > 25 mm) might be a risk factor.

Conclusions

We reported a post-SCL-CHEP complication “Inverted epiglottis”. Extensive excision of the epiglottic petiole, patients with a low vallecula profile, and incorrect suturing of epiglottic petiole during pexis are the three factors most related. Inverted epiglottis was treatable and most of the laryngeal function could be retrieved.     

Thyroid gland flap minimizes mucosal defects at supracricoid partial laryngectomy with cricohyoidoepiglottopexy

Wound infection is a major complication after supracricoid partial laryngectomy with cricohyoidoepiglottopexy (CHEP) for radiation therapy failure. A 60-year-old man received chemoradiotherapy for a glottic carcinoma. CHEP, reusing the thyroid gland flap (TF), was performed because the cancer recurred after a salvage vertical partial laryngectomy following radiation therapy failure. The TF was sutured to the supraglottis and cricoid cartilage mucosa to minimize mucosal defects before the hyoid bone and cricoid cartilage were sutured. Wound healing after CHEP was good without infection. After decannulation, oral food intake was possible without aspiration, and speech function was comparable to that of other patients who had supracricoid partial laryngectomies. Histopathological examination revealed a close connection between the TF and its surrounding tissues without fibrous scarring. TF may improve wound healing after CHEP for radiation failure by minimizing mucosal defects.

Functional outcomes after supracricoid laryngectomy

OBJECTIVES: Local control and 5-year survival rates are similar for patients undergoing total laryngectomy and supracricoid laryngectomy for the treatment of advanced-stage laryngeal carcinoma. However, comprehensive studies of functional outcomes after supracricoid laryngectomy are lacking. STUDY DESIGN: Cohort study. METHODS: This investigation provides objective voice laboratory data, skilled listener impressions of voice samples, swallowing evaluations, and patient self-perceptions of speech ability obtained from 10 supracricoid laryngectomees. RESULTS: Results demonstrated variable acoustic and speech aerodynamic disturbances, hoarse-breathy vocal quality, and speech dysfluency. Patients' self-perceptions of voice revealed severe dysphonia that induced certain emotional, physical, and functional setbacks. However, blinded judges rated these individuals as possessing intelligible speech and communication skills. All patients demonstrated premature spillage of the bolus and varying degrees of laryngeal penetration, aspiration, and retention during swallowing studies. However, each patient used a compensatory strategy to protect the airway. Voice and swallowing abilities appeared to depend on the mobility of the arytenoid cartilages, base of tongue action, and residual supraglottic tissue for the creation of a competent neoglottal sphincter complex that vibrated during phonation efforts and protected the airway during deglutition. CONCLUSIONS: Supracricoid laryngectomy avoids the potential complications, limitations, and emotional problems associated with a permanent tracheostoma. All patients demonstrated intelligible voice and effective swallowing function postoperatively, supporting supracricoid laryngectomy as a suitable alternative surgical approach to the total laryngectomy in select patients.     

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.     

Oncologic and functional outcomes of salvage supracricoid partial laryngectomy

Abstract

Background: Supracricoid partial laryngectomy (SCL) can have a positive impact on patients’ quality of life by circumventing dysphagia and voice problems resulting from creation of a permanent stoma after conventional total laryngectomy (TL) surgery.

Aims/Objectives: The aim of this study was to investigate the oncologic and functional outcomes of salvage SCL for recurrent laryngeal carcinoma.

Material and methods: Forty-five patients that underwent salvage surgery for recurrent laryngeal carcinoma between January 2004 and May 2015 after initial treatment failure were included in this retrospective study.

Results: Overall survival and disease free survival were non-significantly higher in the salvage SCL group (n?=?14) than in the salvage TL group (n?=?31) (87.5 versus 56.5%, 53.4 versus 41.9%). Multivariate analyses showed only positive resection margin to be significantly associated with survival and recurrence (HR 9.974, p?=?.007, and HR 9.196, p?=?.002, respectively). In the salvage SCL group, 92.8% achieved successful decannulation and all patients returned to an oral diet. All patients in the salvage TL group sustained a permanent stoma and conversation was possible only through esophageal voice or a voice prosthesis. 74.2% of patients in the group were able to tolerate an oral diet.

Conclusions and significance: Salvage SCL showed comparable oncologic outcomes and favorable functional outcomes relative to the classic salvage TL. This study could provide a sufficient basis of SCL as salvage treatment for recurrent laryngeal carcinoma in selected patients.     

Partial vertical laryngectomy for recurrent glottic carcinoma

Partial vertical laryngectomy for recurrent glottic carcinoma was performed in 61 patients according to stringent criteria. The great majority of the recurrent tumours appeared within 2 years of radiotherapy (80%). The mean follow-up after surgery was 79 months. At 5 years 85% of the patients were free of local recurrence. Nine patients (15%) developed a local recurrence; eight of them underwent total laryngectomy; one patient refused the operation and died. Seven patients died of other causes. The actuarial overall survival rate was 88% at 5 years. Post-operative complications were seen in 12 patients (20%); nine of these patients developed airway problems. One patient underwent total laryngectomy for severe aspiration, the others finally were decannulated. The results of this study indicate that partial vertical hemi-laryngectomy for irradiation failures is a safe procedure with good results without undue morbidity.

The role of supracricoid laryngectomy for glottic carcinoma recurrence after radiotherapy failure: a critical review

Conclusions.In the near future salvage supracricoid laryngectomy (SCL) will be used more extensively for failures of radiotherapy for glottic carcinoma. Objectives. Primary radiotherapy has been used for patients with early glottic carcinomas in northern Europe and North America for more than half a century. Local recurrences after radiotherapy for glottic malignancies occur in 5–25% for T1 carcinomas and in 15–50% for T2 carcinomas. The classic choice as salvage surgery in cases of glottic squamous cell carcinoma recurrence after irradiation failure is total laryngectomy. The development of extended conservation procedures such as SCL has permitted an increasing number of successful partial laryngectomies that save laryngeal functions after radiotherapy failure. SCL allows the creation of a neo-larynx, permitting both swallowing and speech; in most cases the tracheostoma can be closed. Methods. The electronic database Pubmed was searched without publication date limits. Results. Considering available data (103 cases), 84.5% of the cases treated with salvage SCL for irradiation failure did not present a new local recurrence; laryngeal recurrences after salvage SCL (15.5%) were successfully treated with total laryngectomy in 66.7% of the cases. Tracheostoma closure was possible in all except two cases after a mean period ranging between 12 and 28 days. Swallowing results seemed good, with longer recovery time in irradiated than in non-irradiated patients who underwent SCL. Voice quality determined with psychoacoustic methods had acceptable intelligibility.     

Laryngeal preservation with supracricoid partial laryngectomy results in improved quality of life when compared with total laryngectomy

OBJECTIVES/HYPOTHESES: Study 1: To assess the oncologic outcome following supracricoid partial laryngectomy (SCPL). Study 2: To compare the quality of life (QOL) following SCPL to total laryngectomy (TL) with tracheoesophageal puncture (TEP). Study 3: To analyze whole organ TL sections to determine the percentage of lesions amenable to SCPL STUDY DESIGN: Study 1: A retrospective review of patients who underwent SCPL. Study 2: A non-randomized, prospective study using QOL instruments to compare patients who underwent either SCPL or TL Study 3: A retrospective histopathologic study of TL specimens assessed for the possibility of performing an SCPL. METHODS: Study 1: Twenty-five patients with carcinoma of the larynx underwent SCPL between June 1992 and June 1999. Various rates of oncologic outcome were calculated. Study 2: Thirty-one patients participated in the QOL assessment. This included the SF-36 general health status measure, the University of Michigan Head and Neck Quality of Life (HNQOL) instrument, and the University of Michigan Voice-Related Quality of Life (VRQOL) instrument. Study 3: Ninety surgical specimens were obtained and studied from the total laryngectomy cases in the Tucker Collection. Multiple sites were evaluated for the presence of carcinoma A computer program was written to classify whether the patient was amenable to SCPL. RESULTS: Study 1: The overall local control rate was 96% (24/25). The local control rate following SCPL with cricohyoidoepiglottopexy (CHEP) was 95% (20/21). The local control rate following SCPL with cricohyoidopexy (CHP) was 100% (4/4). Study 2: The SCPL had significantly higher domain scores than TL and TEP in the following categories for the SF-36: physical function, physical limitations, general health, vitality, social functioning, emotional limitations, and physical health summary. The significantly higher domains for the SCPL when compared with the TL and TEP for the HNQOL were eating and pain. Finally, when voice-related QOL was assessed with the V-RQOL, the domains of physical functioning and the total score were significantly better with SCPL when compared with TL and TEP. Study 3: Forty of 90 (44%) laryngeal whole organ specimens were determined to be resectable by SCPL. In 16 (18%) specimens, the patients could have undergone SCPL with CHEP and in 24 (27%) specimens the patients could have undergone SCPL with CHP. Among the 40 (44%) specimens determined to be able to have undergone SCPL, 19 were glottic (1 T1, 15 T2, 3 T3) and 21 were supraglottic (9 T2, 12 T3). CONCLUSIONS: 1) A review of the literature and an analysis of the data in this study indicate that excellent local control may be expected following SCPL. 2) The QOL following SCPL, as measured by three validated QOL instruments, is superior to TL with TEP. 3) A histologic assessment of whole organ sections of TL specimens indicates that many patients who have been subjected to TL may have been candidates for SCPL. 4) If the indications and contraindications are rigorously adhered to, SCPLs are reasonable alternatives to TL in selected cases.     

Supracricoid partial laryngectomy cricohyoidoepiglottopexy (SCPL-CHEP) versus vertical partial laryngectomy for the treatment of glottic carcinoma

The study aimed to compare the survival rate and functional outcome of supracricoid partial laryngectomy cricohyoidoepiglottopexy (SCPL-CHEP) and vertical partial laryngectomy (VPL) in the treatment of glottic carcinoma. Thirty-nine patients underwent SCPL-CHEP and 45 patients underwent VPL between 2002 and 2007. Post-operative clinical staging were performed according to the UICC staging criteria (2002). The primary endpoints were survival time and recurrence rate. The secondary endpoints were the laryngeal functions including pronunciation, swallowing, and respiration. Overall, the estimated mean survival time was 75.6 months. There was no significant difference in survival times between the two groups (P = 0.496). The SCPL-CHEP group had a significantly lower post-operative local recurrence rate than VPL group (2.6 vs. 17.8 %, P = 0.033). Significantly longer nasogastric tube removal (22 vs. 14 days, P < 0.001) and tracheostomy decannulation (38.5 vs. 15 days, P < 0.001) times in SCPL-CHEP group was observed with the VPL group, respectively. Significantly higher aspiration rates were observed at 3, 6, and 12 months in the SCPL-CHEP group compared with the VPL group (P < 0.001, P < 0.001, P < 0.05, respectively). Although the survival rate was not significantly different between the two groups, the local regional control rate and organ preservation in the supracricoid partial laryngectomy cricohyoidoepiglottopexy group was better than those observed in the vertical partial laryngectomy group.     

Supracricoid laryngectomy with cricohyoidopexy for recurrence of early-stage glottic carcinoma after irradiation. Long-term oncological and functional results

Conclusions These results suggest that, in selected cases, SCL-CHP may be used to treat laryngeal carcinomas after radiation failure, with good oncological and functional results.

Objectives Radiotherapy and surgery are believed to be equally effective and highly successful in the management of T1-staged glottic carcinomas. An almost normal post-therapy voice is considered the main advantage of irradiation over the surgical approach. On the other hand, when a tumour recurs after radiotherapy, it is more likely to extend beyond its original site, making total laryngectomy necessary in most cases. However, in selected cases, conservative laryngeal surgery is possible. At present only a few reports in the literature have documented the oncological and functional outcome of supracricoid laryngectomy with cricohyoidopexy (SCL-CHP) in the treatment of laryngeal recurrence after irradiation.

Material and methods We describe seven cases of rT2–T3 laryngeal squamous cell carcinomas that recurred after radiotherapy and were treated with salvage SCL-CHP between 1989 and 1997 at the Department of Otolaryngology, University of Ferrara. The disease-free interval following initial radiotherapy ranged from 13 to 132 months (mean 54 months) in 6 patients; 1 patient underwent 2 courses of irradiation treatment 103 and 8 months prior to surgery.

Results The mean post-SCL-CHP follow-up period exceeded 10 years (range 72–173 months). Only the patient who underwent 2 courses of radiation therapy before surgery experienced laryngeal recurrence 48 months after surgery. All patients were decannulated and recovered the ability to swallow. Vocal quality was significantly rough and breathy but was satisfactorily intelligible in all patients. Four patients had wound healing problems; 1 of them developed a laryngotracheocutaneous fistula 15 months after SCL-CHP as a consequence of chondronecrosis, prompting total laryngectomy.     

Prognostic value of resection margins in supracricoid laryngectomy

OBJECTIVES: The objective was to assess the prognostic value of surgical margin involvement in patients treated for squamous cell carcinoma of the larynx. STUDY DESIGN: Retrospective study. METHODS: A review was made of 253 patients treated with supracricoid laryngectomy between 1984 and 2001. A histopathological study on the surgical resection margins was performed in all cases. The incidence of local recurrence was correlated with the histological features of resection margins. RESULTS: Forty patients (15.8%) were identified as having positive margins: 29 had invasive carcinoma and 11 had dysplastic lesions. The remaining 213 patients (84.2%) had negative margins. Subsequent follow-up showed that 19 of 253 patients developed local recurrence and 3 patients developed regional recurrence. Nine of these patients had positive resection margins (six with invasive carcinoma and three with dysplastic lesions), and 10 had negative resection margins. Overall survival at 3 years was significantly higher for patients without recurrence than for patients with local or regional failure (89.9% vs. 45.5% [P <.05]). CONCLUSION: According to results of the study, patients with positive resection margins developed local recurrence more frequently than those with clear resection margins (P <.05).     

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.     

Surgery versus radiation for T1 glottic carcinoma: Second primary considerations

Although early glottic carcinoma is managed with radiation therapy (RT) or surgery, there is limited data on differences in second primary cancers of the larynx. We utilized the Surveillance, Epidemiology, and End Results (SEER) database to query T1 glottic carcinomas and assess the incidence of second primary laryngeal malignancies. Cumulative hazard for second primary laryngeal malignancies was compared with the log‐rank method. Among 844 surgical and 2,272 RT cases, observed‐to‐expected incidence ratios of laryngeal second primaries were 10.19 (5.89–16.55) and 6.87 (4.64–9.81) per 10 thousand person‐years, respectively. Mean person‐years at risk were comparable at 8.16 years (surgery) and 8.01 years (RT), and relative increased risk of laryngeal second primary was 20.95 (surgery) versus 14.09 (RT) per 10 thousand person‐years. Mean times to development of a second primary were also comparable (304 vs. 305 months, P = 0.898). Thus, second laryngeal primary development is analogous between cases treated with surgery alone versus RT. Continued discussion and investigation of surgery versus RT for early glottic squamous cell carcinoma will need to leverage these findings, along with ongoing investigation of voice and survival outcomes, to develop more well‐informed treatment algorithms.
