Supracricoid partial laryngectomy in the treatment of laryngeal cancer: univariate and multivariate analysis of prognostic factors.

OBJECTIVES: To evaluate the oncological results of supracricoid partial laryngectomy as a treatment for selected glottic and supraglottic cancer in a large series of patients who had undergone uniform treatment over a 16-year period and to determine the different prognostic factors that may influence local control and survival. DESIGN: Retrospective clinical study. SETTING: Academic tertiary referral medical center. PATIENTS: The study population comprised 253 consecutive patients (234 men and 19 women) with glottic and supraglottic squamous cell carcinoma. The mean age was 58 years for men and 59.2 years for women. INTERVENTION: Supracricoid partial laryngectomy: 180 patients had undergone cricohyoidopexy and 73 had undergone cricohyoidoepiglottopexy. MAIN OUTCOME MEASURES: Local control and overall survival. Potential prognostic factors for local control and survival were evaluated with univariate and multivariate models. RESULTS: The 3-, 5-, 10-, and 16-year overall survival rates in this group of 253 patients were 85.8%, 79.1%, 57.6%, and 57.6%, respectively. With regard to local control, univariate and multivariate analyses showed that a positive resection margin was the only important predictor of local control and that a dysplastic lesion at the margin of resection is just as aggressive as the presence of invasive carcinoma. When considering the prognostic factors influencing survival, univariate analysis showed that the tumor category, lymph node category, tumor stage, and recurrence all had a significant influence on the survival rate. Multivariate analysis showed that the most important predictor of survival was recurrence. CONCLUSIONS: Supracricoid partial laryngectomy is a valid choice in the treatment of selected glottic and supraglottic cancer while maintaining laryngeal functions and achieving a high rate of local control. T category, N category, tumor stage, positive resection margins, and recurrence are the most important predictors of oncological outcome.

Anesthetic and operative management of potential upper airway obstruction.

Potential or actual supraglottic airway obstruction becomes critical when general anesthesia is begun. Four cases illustrated such obstruction, and the anesthetic and surgical management of each condition was critical. In carcinoma of the supraglottic larynx and in pharyngeal abscess, the unobstructed airway in the conscious patient became impossible to secure once general anesthesia was begun. Unappreciated pathological deformity prohibited endotracheal intubation, and anesthesia precipitated obstruction. In epiglottitis and peritonsillar abscess, the nature of the impending airway obstruction was appreciated, and the selection of a safe technique to secure the airway was made. Anesthetic and surgical management of potential supraglottic obstruction includes five options: (1) oral tracheal intubation by laryngoscopy while the patient is awake; (2) awake nasotracheal intubation; (3) inhalation induction by general anesthesia with intubation; (4) rapid induction with barbiturates and muscle relaxants with intubation; and (5) tracheostomy with local anesthesia.

Conservation laryngeal surgery. A critical analysis.

Three hundred forty-two cases of laryngeal cancer were treated at the University of Michigan, Ann Arbor. One hundred ten supraglottic cancers and 150 glottic cancers were studied in depth. Conservation surgery was performed on 63 patients. Determinate two-year disease-free survival for glottic cancer was 90% in those irradiated primarily, 83% for those treated with vertical hemilaryngectomy, and 58% in the group that had total laryngectomy. Supraglottic cancers had a determinate survival rate at two years of 62% for those irradiated primarily, 80% for those treated with a supraglottic laryngectomy, and 62% when total laryngectomy was required. The cost of preserving the respiratory and sphincteric functions of the larynx in some cases amounted to the morbidity associated with a protracted hospital stay, altered deglutition, instances of a weak but functional voice, and the possibility of a permanent tracheostomy. Despite high recurrence rates of 30% to 40%, the overall determinate survival with salvage was an acceptable 80% for the conservation surgery group.

Gender influences subsite of origin of laryngeal carcinoma.

The relationship of gender to laryngeal cancer is not well understood. We analyzed 688 laryngeal cancers diagnosed in Kansas from 1980 through 1989 for sex differences in subsite distribution (glottis, supraglottis, subglottis, and laryngeal cartilage) as well as survival, histologic grade, and age at diagnosis. The ratio of glottic to supraglottic tumors was 22.12:1 in men and 0.56:1 in women, a highly significant difference. Survival in glottic tumors was significantly better than in supraglottic tumors, but survival was not significantly better for women than it was for men. Glottic tumors were significantly more likely than were supraglottic tumors to be of low-grade malignancy for all subjects and for male subjects alone, but not for female subjects alone. Women were younger at time of diagnosis than were men, but not significantly so. Gender is an important factor in the genesis of laryngeal cancer.

Clinical relevance of p53 and bcl-2 protein over-expression in laryngeal squamous-cell carcinoma.

We investigated immunohistochemically the clinical relevance of the over-expression of the apoptosis-regulating proteins p53 and bcl-2 in a homogeneous series of 149 laryngeal squamous-cell carcinomas. p53 was over-expressed in 75 cases and bcl-2 in 39 cases. p53 and bcl-2 co-expression was found in 21 cases. p53 and bcl-2 immunoreactivity was significantly associated with poor histological differentiation and lymph-node metastases. Moreover, a significant statistical correlation was found between bcl-2 expression, supraglottic tumor site and advanced disease stage. p53/bcl-2 co-expression was significantly associated with poor differentiation, tumor extension, the presence of lymph-node metastases and advanced clinical stage. Univariate analysis showed that a lower probability of survival was significantly associated with supraglottic site, tumor extension, advanced clinical stage and p53/bcl-2 co-expression, but not with p53 or bcl-2 considered separately. In multivariate analysis, only tumor extension and supraglottic site retained their prognostic value. Our data suggest that clinical staging remains the most reliable predictive indicator of survival in patients with laryngeal carcinoma.

Neo-adjuvant chemotherapy and supracricoid partial laryngectomy with cricohyoidopexy for advanced endolaryngeal carcinoma classified as T3-T4: 5-year oncologic results.

BACKGROUND: Historically, total laryngectomy with voice-prosthesis insertion and near-total laryngectomy were the surgical options advocated for advanced supraglottic and transglottic tumors classified as T3-T4. METHODS: The present retrospective study reviewed our experience with neo-adjuvant chemotherapy and supracricoid partial laryngectomy with cricohyoidopexy (SCPL-CHP) in a series of 60 patients with an isolated, untreated, advanced supraglottic/transglottic invasive squamous cell carcinoma classified as T3-T4. RESULTS: The Kaplan-Meier 5-year actuarial survival, local failure, nodal failure, and distant metastasis estimates were 72.7%, 8.3%, 9.2%, and 9.8%, respectively. Survival was significantly reduced in patients with nodal failure (p = .001) and distant metastasis (p = .007). Overall, a 91.7% laryngeal preservation rate and a 98.3% local control rate were achieved. CONCLUSION: Our report was a retrospective analysis and did not present a control group exclusively managed with SCPL-CHP. Therefore, we were unable to demonstrate that the use of neo-adjuvant chemotherapy prior to SCPL-CHP allowed for an increase in local control, laryngeal preservation, and survival. However, the use of neo-adjuvant chemotherapy allowed for remobilization of a fixed arytenoid cartilage in 10 patients who thus became amenable to SCPL-CHP. The key role of neo-adjuvant chemotherapy in this series was as a prognostic indicator for suitability for SCPL-CHP in the case of supraglottic-transglottic tumor with arytenoid cartilage fixation. Our data also supported the notion that SCPL-CHP is a valid alternative to total laryngectomy with voice prosthesis insertion and near-total laryngectomy in selected patients with a previously untreated supraglottic/transglottic invasive squamous cell carcinoma classified as T3-T4. Furthermore, the successful use (in terms of surgical outcome, laryngeal preservation, and survival) of SCPL-CHP after neo-adjuvant chemotherapy suggested that laryngeal organ-preservation strategies, in advanced endolaryngeal transglottic and/or supraglottic invasive squamous cell carcinoma, should not be limited to the use of laryngeal radiotherapy after neo-adjuvant chemotherapy.

Routine inclusion of level IV in neck dissection for squamous cell carcinoma of the larynx: is it justified?

BACKGROUND: Dissection of levels II-IV as part of an elective or therapeutic neck dissection is common practice during laryngectomy for laryngeal squamous cell carcinoma (SCC). The necessity of routine dissection at level IV has recently been questioned. The purpose of this study was to find the incidence of level IV metastases in patients with transglottic and supraglottic SCC who underwent neck dissections. METHODS: The charts of 71 suitable patients were reviewed. Forty-two had supraglottic primary cancers, and 29 had transglottic primary tumors. Levels II-IV had been removed in them all, and their neck specimens were marked according to the levels of the neck. The surgical specimens were pathologically diagnosed. RESULTS: Of 43 patients who underwent elective lateral neck dissection, the only one (2.3%) with level IV metastases also showed metastases at level II. Nine (32%) of the other 28 patients with clinical adenopathy had level IV metastases. CONCLUSIONS: Dissection of level IV as part of a therapeutic neck dissection for supraglottic and transglottic SCC is recommended for patients with clinically enlarged lymph nodes, but its necessity in the absence of detectable adenopathy is challenged.

Recovery of postoperative swallowing in patients undergoing partial laryngectomy.

This study assessed the achievement of postoperative swallowing in patients undergoing partial laryngectomy surgery. Oropharyngeal swallow efficiency was used to predict time to achievement of outcome. Fifty-five patients were followed for up to 1 year in two hemilaryngectomy and four supraglottic laryngectomy groups. Within 10 days of healing, a videofluoroscopic evaluation enabled the measurement of swallowing efficiency. Times to achievement of oral intake, removal of feeding tube, preoperative diet, and normal swallow were analyzed using actuarial curves. Patients with hemilaryngectomies achieved swallowing rehabilitation sooner than patients with nonextended supraglottic laryngectomies (p < .05) who, in turn, achieved swallowing function sooner than did patients undergoing supraglottic laryngectomies with tongue base resection (p < .05). Median time to attainment of preoperative diet in these three groups was 28 days, 91 days, and > 335 days, respectively. Higher early postoperative oropharyngeal swallow efficiency was related to earlier achievement of oral food intake and of preoperative diet (p < .05). Results show that the time course for swallowing rehabilitation covers an extended postoperative period. In some surgical groups, functional swallowing and eating may be achieved within 3 months of surgery while for other types, significant impairment remains up to 9 months postoperatively Early radiographic assessments of swallowing function are useful in predicting the time to swallow recovery. Recovery of swallowing ability may be delayed in patients who have not achieved oral intake before radiotherapy is started.

Randomized study of local control and survival following radical surgery or radiation therapy in oral and laryngeal carcinomas.

From 1971 to 1975, 100 patients with glottic, supraglottic, and oral cavity lesions were prospectively randomized between primary radiation treatment and primary surgery. Local control and survival were similar with either treatment for lesions of the oral cavity or supraglottic larynx. Comparison between radiation alone and surgery alone for T1 and T2 glottic laryngeal lesions showed local control rates of 76% and 100% (P=0.32); after secondary salvage attempts, local control rates were 82% and 100%, respectively (P= 0.52). Neither result approached statistical significance. Successful radiation for early glottic larynx lesions resulted in superior deglutition and equivalent voice function compared to successful primary treatment with conservation laryngectomy. For oral cavity lesions, swallowing was impaired in the same percentage of radiated and operated patients, but fewer primary radiation patients had articulation difficulties. Among the patients with supraglottic larynx lesions, aspiration was not a problem with either radiation or surgery, but successful radiation perhaps maintained a slightly better voice quality.

Radiotherapy in N0 head and neck cancer patients.

The efficacy of elective radiotherapy in N0 cancer of the oropharynx, hypopharynx and supraglottic larynx was assessed retrospectively in a large series of head and neck cancer patients treated at the Institut Curie between 1958 and 1976. Despite a significant incidence of false-negative cases accompanied by extra-capsular tumor spread, radiation tissue doses of 4500-5500 cGy were highly successful in preventing nodal disease in clinically negative necks. Isolated node failure occurred in only 2% of 611 cases of oropharyngeal and pharyngolaryngeal cancer from a total group of 1646 patients and 2% of 237 N0 cases of supraglottic vestibular cancer taken from a series of 340 patients. The impact of neck status on survival and disease-free survival is discussed. Present findings show that elective irradiation of the neck is easily integrated into the radiation management of primary pharyngeal and supraglottic laryngeal cancers and results in no additional morbidity to patients so treated.

Pharyngoesophageal pressure in patients with swallowing disorders.

We developed and tested a pressure transducer to correctly determine swallowing pressure at different sites in the pharynx. In normal individuals three pressure peaks were obtained in the mesopharynx, hypopharynx and cervical esophagus, respectively. A patient with central dysphagia demonstrated markedly low mesopharyngeal and hypopharyngeal swallowing pressure. One tongue cancer patient who had undergone right hemiglossectomy, including partial resection of the root of the tongue and bilateral superior neck dissection, had markedly low swallowing pressure in the mesopharynx and vallecula area. Another supraglottic cancer patient treated by supraglottic horizontal partial laryngectomy showed extremely low swallowing pressure in the supraglottic area. Based on our findings, we suggest that measurements using a pressure transducer such as the one described here should be used in combination with radiographic study to diagnose swallowing anomalies correctly. Data obtained with the pressure transducer will allow the clinician to identify the site responsible for postoperative dysphagia as well as its severity, and facilitate planning of reconstructive surgery when required.

[Primary radiotherapy of laryngeal carcinoma. An analysis of the therapeutic results and of the the relapse behavior in 283 patients].

PURPOSE: In the treatment of laryngeal carcinoma definitive radiotherapy results in a similar outcome as surgical treatment in the early stages with a lower morbidity rate and good functional results. In fact no randomized studies exist, so far, and the optimal treatment concept for the different stages is not well defined. The following study analyses retrospectively the treatment results and the recurrence data in patients with a squamous cell carcinoma of the larynx treated with definitive radiotherapy. PATIENTS AND METHOD: Two hundreds and eighty-three patients with carcinoma of the larynx were treated with radiation therapy in the department of radiology of the LMU München between September 1971 and June 1986. Twenty-six patients (9.2%) were female and 257 (73.1%) male. The median age was 68.5 years, respectively 70 years. All patients had a histologically confirmed squamous cell carcinoma of the larynx. No true subglottic cases were observed. Forty-one (14.5%) tumors were localized supraglottically, 207 (73.1%) glottically. Thirty-five patients had a T4 tumor with glottic and supraglottic involvement. In 147 patients the histopathological grading was evaluable: 32 tumors were classified as G1, 95 as G2, 15 as G3 and 5 as G4. According to the UICC classification of 1979 25 patients had a carcinoma in situ (Tis), 93 patients had a stage T1, 90 stage T2, 40 stage T3 and 35 stage T4. Two hundreds and thirty-three of 283 (82.3%) had no lymph node involvement. In 50 patients clinically a lymph node involvement was observed. 22 patients had a stage N1, 5 patients stage N2 and 23 patients stage N3. An external beam radiation mostly with cobalt-60 was performed with a mean dose of 61.9 Gy. RESULTS: The 5-years relapse-free survival for the whole group was 61.7%. The probability for "no evidence of disease" (NED) depended on tumor stage and localisation (glottic tumors: Tis/T1 90.5%: T2 59.4%: T3 39.6%: [5-year NED]; supraglottic tumors T1 64.2%: T2/3 28.6%: T4/N3 24.7% [3-year NED]). Other significant prognostic factors besides T-stage were N-stage (NO vs. N1-3: 3-year recurrence-free survival 68% vs. 37.2%, p < 0.001) and histopathologic grading (G1 vs. G3/4: 3-year recurrence-free survival 74% vs. 37.1%, p < 0.01). One hundred and twenty-two (43.1%) patients had a recurrence, which occurred in 75.4% local, in 12.3% loco regional, in 8.2%, with distant metastases and 4.1% combined. In 50 patients with a recurrent disease a salvage therapy was carried out. Thereby 17 patients achieved a complete response. CONCLUSION: Even for the here described negatively selected patient group with a high median age and multimorbidity, good local control rates could be achieved especially in early stages with definitive radiation therapy. In more advanced stages even in elderly patients a combined surgical-radiotherapeutic treatment should be performed.

Lateral pharyngeal wall motion during swallowing using real time ultrasound.

B-mode ultrasound imaging has been used primarily to detect temporal and spatial movements of the tongue during the oral preparatory and oral stages of swallowing. The purpose of this study was to investigate the application of M-mode (motion mode) ultrasound imaging as a method to quantify the duration and displacement of single regions along the lateral pharyngeal wall during swallows of two bolus volumes and during three swallow maneuvers (supraglottic, super-supraglottic and Mendelsohn maneuver). In 5 normal subjects, simultaneous B/M-mode images were captured at two regions along the lateral pharyngeal wall. Computer-assisted video analysis of each swallow sequence provided spatial coordinates and durational measures. Results indicated no significant differences in displacements of the lateral pharyngeal wall across bolus volumes, swallow maneuvers, or recording sites. Significant differences (p < 0.001) in lateral pharyngeal wall duration occurred as a function of volitional swallow maneuvers. Greater durations (p < 0.05) were found for the Mendelsohn and super-supraglottic swallow maneuvers. The data demonstrate that B/M-mode ultrasound imaging provides a simple, noninvasive method to visually examine movements of the lateral pharyngeal wall and may provide a clinical method for assessing the effects of direct swallowing therapies at the level of the mid-oropharynx.

[Extranodal non-Hodgkin's lymphoma of MALT-type stage I. A case report].

BACKGROUND: Extranodal non-Hodgkin's lymphoma are mostly localized in the gastrointestinal tract. A small number of these lymphoma arise from specialized lymphoid cells, the so-called mucosa-associated lymphoid tissue (MALT). We describe one case with a metachronous occurrence of a MALT-type lymphoma of the conjunctiva of both eyelids and supraglottic larynx. PATIENT AND METHOD: A 56-year old woman was first treated in August 1990 for a low-grade B-cell lymphoma in the conjunctiva of the left eyelid. 42 months later an extranodal B-cell lymphoma, located in the conjunctiva of the right eyelid, was found. After a father period of 48 months a MALT-type lymphoma arose in the supraglottic larynx. The findings of staging examinations were normal. The final diagnosis was low-grade B-cell lymphoma of the MALT-type, limited to the conjunctival eyelids and supraglottic larynx, with the clinical staging of IE A. Treatment consisted of a LASER-resection followed by a locoregional radiotherapy, with the dose of 40 Gy. RESULTS: Currently no evidence of disease (NED) at all sites can be proven. CONCLUSIONS: Extranodal, primary low grade B-cell MALT-type lymphoma are rare. In the literature only few cases of each larynx- and conjunctival eyelid involvement described. The radiotherapy has been reported to achieve a long time of relapse-free interval. The present case demonstrates, that even the recurrence of an extranodal, primary low-grade B-cell MALT-type lymphoma responds well to local radiotherapy and can also have a long period of no evidence of disease.

Feasibility of supracricoid laryngectomy based on pathological examination.

Partial horizontal supracricoid laryngectomy with cricohyoidopexy at the Department of Otolaryngology, Medical University of Białystok, involves resection of the entire thyroid cartilage with the pre-epiglottic and paraglottic spaces. Experience has shown that this technique will permit adequate phonation, respiration and deglutition in selected advanced cases of supraglottic and glottic carcinoma. The purpose of this study was to verify histologically the indications for this surgery by examining sections of whole-organ laryngeal specimens. Post-laryngectomy specimens from 90 patients with otherwise previously untreated supraglottic (48), transglottic (22) and glottic (20) carcinomas were reviewed retrospectively. The majority (66) of the specimens were staged as pT4. Findings showed that 22 of the specimens analyzed (mostly supraglottic tumors) could have been eradicated by supracricoid laryngectomy alone. The present study confirmed the principles of supracricoid laryngectomy for selected large tumors.

Region-specific immunological response of the different laryngeal compartments: significance of larynx-associated lymphoid tissue.

The occurrence of primary extranodal marginal-zone B-cell lymphoma [of the mucosa-associated lymphoid tissue (MALT) type] has only been described in the supraglottic region, implying that preexistent organized lymphoid tissue is present at that site only. To date, studies have not established clearly whether organized MALT shows a site-related distribution in the larynx. The supraglottic region of the false vocal folds and the subglottis from 87 unselected cadavers with no known history of nasal, oral, pharyngeal, laryngeal, tracheal, or esophageal disease were examined for the presence of organized MALT. Organized lymphoid tissue was found with the cytomorphological and immunophenotypic features of MALT in 100% of false vocal folds of children and in more than 90% of adolescents, decreasing to 7.1% in persons in their sixth decade, whereas MALT was completely absent in the subglottis in all age groups. The results explain why primary extranodal marginal-zone B-cell lymphoma has only been described in the supraglottic region but is absent in the subglottis. Moreover, the results suggest a region-specific immunological response of the different laryngeal areas as reflected in clinical observations and animal studies. However, the impact on presence or absence of laryngeal MALT awaits clarification.

The preepiglottic space revisited: is it significant?

One hundred fifty-four laryngeal specimens were examined by a serial sectioning method to determine the importance of the preepiglottic space (PES) in the spread of cancer. Controversy surrounds the status of the PES in the two major TNM classifications regarding laryngeal anatomy. However, both the UICC (International Union Against Cancer) and the AJCCS (American Joint Commission on Cancer Staging) imply a T3 grading for tumors invading the PES. Several variables relating to laryngeal cancer spread were entered into a computer program designed to calculate statistical relationships. Of all laryngeal cancers, PES invasion usually occurred in association with primary supraglottic tumors. Preepiglottic space invasion was also found in association with more than half of the cases involving base of tongue and strap muscle invasion. It was also noted in more than half of the cases with transglottic cancer spread. Statistically, these relationships were all highly significant. These findings suggest that PES invasion should be considered equivalent to the spread of cancer outside the larynx, and should therefore be assigned a T4 localized even when advanced, casting doubt on supraglottic partial laryngectomy as a curative procedure in all but the earliest supraglottic tumors.

Planned preoperative radiation therapy for advanced laryngeal carcinoma.

One hundred ten patients with predominantly advanced laryngeal carcinoma were treated in the period 1969-1978 with planned preoperative radiation therapy followed by surgery. Site distribution was: 63 supraglottic, 26 glottic, 15 transglottic and 6 subglottic. There were 4 Stage II patients, 66 Stage III and 40 Stage IV. Preoperative radiation therapy consisted of Telecobalt irradiation to a total dose of 25 Gy given to a target volume encompassing the larynx and regional neck nodes, given in 5 equal daily fractions of 5 Gy in 5 consecutive days. Surgery was performed 2 days later. Total laryngectomy was performed on 48 patients, total laryngectomy with neck dissection on 55 patients, supraglottic laryngectomy on 5 and supraglottic laryngectomy with neck dissection on 2 patients. Crude actuarial 5 and 10 year survival probability for the whole group is 71 and 61%, respectively. The corrected 5 and 10 year survival is 75%. For patients with T3-T4-N0 tumors 5 and 10 year survival probability is: crude 65 and 58%, and corrected 70% respectively. For T3-T4-N+ crude: 75 and 60% and corrected: 78%. Of 110 patients, one died postoperative, three died of intercurrent disease, five died as a result of second malignancy, and 23 died of their larynx carcinoma: 12/23 because of locoregional failure, and 11/23 because of distant metastasis. We concluded that short intensive preoperative radiation therapy and surgery offer a high cure rate in the treatment of advanced resectable laryngeal carcinoma. The merits of this technique are outlined in the text.
