[Carbon dioxide laser transoral microsurgery for glottic carcinoma in situ].

OBJECTIVE: To evaluate the oncologic results of glottic carcinoma in situ (CIS) treated with transoral carbon dioxide laser microsurgery. METHODS: A retrospective review of 12 patients with glottic CIS previously untreated, treated with carbon dioxide laser transoral microsurgery between January 1990 and December 1999 was conducted. RESULTS: Initial and ultimate local control rates were 75%, and 100%, respectively. Three local failures occurred: two glottic CIS were treated by carbon dioxide laser transoral microsurgery, one squamous cell glottic carcinoma was treated by supracricoid partial laryngectomy with cricohyoidoepiglottopexy. The ultimate rate of laryngeal preservation rate was 100%. CONCLUSIONS: Based on the material of this study, recommended treatment for glottic CIS should be carbon dioxide laser transoral microsurgery. Difficulties in endoscopic exposure of the larynx is a contraindication. Further studies are necessary to confirm these preliminary results.

[Adenocarcinomas of the ethmoid sinuses. Epidemiological data].

OBJECTIVE: The relationship between adenocarcinomas of the ethmoid (ADKE) and wood-dust exposure has been well established. Sino-nasal cancer in wood-workers has been added to the list of occupational disorders in France, as prescribed disease number 47-Bq. PATIENTS AND METHODS: Our data set consisted of 207 cases with sino-nasal cancer (from January 1985 to January 2001). Among these cases, 67.1% were adenocarcinoma. A wood dust exposure has been reported in 96.4% cases. The mean duration of wood dust exposure was 30 years. The mean latency between the end of the exposure and the diagnostic was 10.6 years. RESULTS: Our epidemiological data confirmed those from the biomedical literature. The occupations at greatest risk are furniture workers, sawmill workers, carpentry workers, and other wood product workers. Two components of exposure - duration and average level - contributed independently to the overall elevated risk. The risk is greater among men who were employed in jobs with the highest wood dust exposure and increases with the duration of exposure. CONCLUSIONS: The preinvasive stages of ADKE (mucostasis/cuboïd metaplasia/dysplasia) are still an unverified hypothesis. ADKE were observed in workers who use "hard" woods. The chemical nature of the carcinogenic factor(s) in wood dust is not known. The factors responsible for induction of ADKE in hard wood-workers probably exist in the wood-dust itself. Tannins were suggested as possible contributing agents to induction of ADKE. In addition to wood dust, exposures may include formaldehyde. Given these facts, it should be possible to define preventive measures, so that incidence of ADKE in professional wood and leather workers should decrease.

Chemotherapy alone with curative intent in patients with invasive squamous cell carcinoma of the pharyngolarynx classified as T1-T4N0M0 complete clinical responders.

BACKGROUND: The current studies documented the results achieved with chemotherapy alone with curative intent in a series of 67 patients with invasive squamous cell carcinoma of the pharyngolarynx classified as T1-T4N0M0 complete clinical responders after a platin-based induction chemotherapy regimen. METHODS: Group I consisted of 36 patients with tumors originating from the glottis. Group II consisted of 31 patients with tumors originating from sites within the pharyngolarynx other than the glottis. A minimum of 3 years of follow-up was achieved. Statistical analyses of survival, local control, lymph node control, distant metastasis, and second primary tumor rates were based on the Kaplan-Meier life-table method. Laryngeal preservation rates and local control rates are presented. RESULTS: The 5-year actuarial survival estimate was 85.1% in Group I patients and 54.8% in Group II patients. Survival was statistically more likely to be reduced in Group II patients compared with Group I patients (P = 0.01). The 5-year actuarial local control estimate was 65.7% in Group I patients and 37.5% in Group II patients. Local failure was statistically more likely to occur in Group II patients compared with Group I patients (P = 0.02). Local control rates after salvage treatment were 100% in Group I patients and 83% in Group II patients. Laryngeal preservation rates after salvage treatment were 100% in Group I patients and 64% in Group II patients. The 5-year actuarial lymph node control estimate was 90% in Group I patients and 73.7% in Group II patients. Lymph node failure was statistically more likely to occur in Group II patients compared with Group I patients (P = 0.04). The 5-year actuarial estimate for patients without distant metastasis was 100% in Group I patients and 90% in Group II patients. Distant metastasis was statistically more likely to occur in Group II patients compared with Group I patients (P = 0.03). The 10-year actuarial estimate for patients without metachronous second primary tumors was 56.4% in Group I and 46.1% in Group II. CONCLUSIONS: The current report 1) contradicts the old dogma of nonchemocurability for invasive squamous cell carcinoma of the upper aerodigestive tract and 2) suggests that the use of a platin-based chemotherapy-alone regimen with curative intent in patients with invasive squamous cell carcinoma of the pharyngolarynx who are classified as T1-T4N0M0 complete clinical responders after receiving an induction chemotherapy regimen is best indicated when the tumor originates from the glottis.

Glutathione-associated enzymes in head and neck squamous cell carcinoma and response to cisplatin-based neoadjuvant chemotherapy.

Glutathione S-transferases (GSTs) are metabolic phase II enzymes that promote reactive metabolite elimination by conjugating them to glutathione (GSH). Because of their important role in xenobiotic metabolism and detoxification, they have been implicated in carcinogenesis processes, especially epithelium transformation. Moreover, their influence on response to chemotherapy in cancer patients has been demonstrated. Genetic polymorphisms for GSTM1, GSTT1 and GSTP1 have been found in human populations and have been shown to have phenotypic consequences. To investigate the role of GST enzymes in carcinogenesis and in response to chemotherapy in patients with head and neck squamous cell carcinoma (HNSCC), GSTP1, GSTM1 and GSTT1 were studied prospectively in a large series of HNSCC patients. Correlations between GST alterations, p53 mutation status and clinical response to chemotherapy were investigated. We showed that the risk of developing laryngeal cancer was increased by 2.6-fold [95% CI 1.6--6.1] in patients with the GSTM1 null genotype and by 2.8-fold [95% CI 0.9--8.1] in patients with the homozygous GSTP1 val105 genotype. Furthermore, individuals with this latter genotype were over-represented in the p53 mutation group (p = 0.05). After storage duration and hemolysis adjustment, a significantly lower plasmatic GSTP1 level was observed in complete responders compared with partial and non-responders (mean: 4.4 +/- 0.06 microg/l, 4.7 +/- 0.06 microg/l and 4.7 +/- 0.07 microg/l; p = 0.05), respectively. The prevalence of p53-mutated tumors was significantly higher in the group of non-responders (81%) compared with partial (60%) and complete responders (64%) (p = 0.05). Two types of multivariate analysis were performed including parameters that have been shown to influence response to chemotherapy significantly in univariate analysis. p53 mutations and high tumor stage are independent factors of non-response to chemotherapy, whereas plasmatic GSTP1 levels and low tumor stage are independent factors of complete response. Our data suggest that GST enzymes are associated with larynx cancer and that their use as predictive factors and treatment targets should be further explored.

[Esophagectomy for squamous cell carcinoma of the esophagus isolated or associated with head and neck cancer: long-term survival].

STUDY AIM: Esophageal squamous cell carcinomas are frequently associated with head and neck cancers. This retrospective study was conducted to compare the long-term outcome of the patients with a double cancer and of the patients with a solitary esophageal cancer after curative management. PATIENTS AND METHODS: From 1989 to 1999, 114 patients with an esophageal carcinoma were included in the study. Among them, 52 had an associated head and neck cancer (metachronous: n = 17 and synchronous: n = 35). Curative treatment was achieved in all patients. The patients were divided in "solitary" and "associated" group. RESULTS: Age, sex distribution, tumor location and histological findings were similar in the two groups. The esophageal resection was an esopharyngolaryngectomy (n = 13), a subtotal esophagectomy with cervical anastomosis (n = 92) and a Lewis-Santy esophagectomy with thoracic anastomosis (n = 9). Operative mortality (8 versus 7.7%), anastomotic leaks rate (14.5 versus 21%) and pneumonia rate (21 versus 9.6%) were not significantly different in the two groups. The mean hospital stay was 27 days. The mean follow-up was 85 +/- 50 months. Five-year survival rates were not significantly different in the two groups (p = 0.6411). In univariate survival analysis the only significant predictive factors were the depth of esophageal tumor invasion (p = 0.0002) and node involvement (p = 0.0373). The presence of head and neck cancer did not affect survival after esophagectomy. CONCLUSION: With an aggressive therapeutic plan, the survival of patients with an esophageal cancer associated to head and neck cancer was similar to the survival of patients with an isolated esophageal carcinoma. Long term esophageal survey seems to be useful to detect more superficial esophageal carcinomas in patients with head and neck cancer.

[Treatment of recurrent unilateral paralysis with thyroplasty with Montgomery implant].

OBJECTIVES: An analysis of thyroplasty with Montgomery implant under local anesthesia for unilateral laryngeal nerve paralysis. PATIENTS AND METHOD: An inception cohort of 21 patients was operated on with a minimum follow-up of 9 months. All patients had severe dysphonia and breathlessness. Seven patients had aspiration with a non efficient cough. RESULTS: The only adverse side effect was a subcutaneous cervical hematoma in one patient. Aspiration disappeared immediately after completion of the thyroplasty. Immediate improvement of speech, cough, and breathlessness was achieved in all patients. Over time, speech and voice remained stable in all patients. Recurrence of aspiration was not encountered. CONCLUSION: Such data supported the notion that the thyroplasty with Montgomery implant under local anesthesia is an extremely valuable option in patients with unilateral laryngeal nerve paralysis.

Objective voice analysis after autologous fat injection for unilateral vocal fold paralysis.

This study was designed to objectively compare a patient's voice after onset of unilateral vocal fold paralysis (UVFP) to his or her own normal voice, and to compare the results after treatment by intrafold injection of autologous fat. Acoustic recordings were obtained for 2 male patients before thoracic surgery and after the onset of iatrogenic left UVFP. Vocal fold augmentation was performed 10 days after UVFP. The acoustic recordings were repeated within 3 days and at 1 month. The phonation quotient, pitch perturbation quotient, amplitude perturbation quotient, harmonics-to-noise ratio, cepstral peak prominence, and long-term average spectrum were analyzed. All parameters improved after treatment, with a return to preparalytic values for most. During the first month, some deterioration was noted. This is the first study comparing a subject's own normal voice to his or her voice after vocal fold augmentation. We recommend overinjection of fat if vocal fold atrophy is expected.

Phonatory mechanisms after vertical partial laryngectomy with glottic reconstruction by false vocal fold flap.

A prospective randomized study was designed to compare phonatory mechanisms in patients treated with frontolateral partial laryngectomy (FLPL) with or without glottic reconstruction with false vocal fold (FVF) mucosal flap. Objective voice assessment was based on computerized acoustic recordings and videolaryngostroboscopy performed before, 1 year after, and 2 years after surgery. Phonatory mechanisms were studied according to the surgical technique and correlated with acoustic recordings. The results showed that supraglottic structures participated in laryngeal closure and voice production in 80% of cases in which a standard FLPL was performed. The FVF mucosal flap was involved in both laryngeal closure and voice production in 54% of patients treated with glottic reconstruction. The type of laryngeal closure (glottic or supraglottic) statistically influenced the acoustic measurements. As glottic closure is more frequent in patients treated with glottic reconstruction, the authors recommend performing reconstruction of the glottis with an FVF mucosal flap when an FLPL is indicated.

Supracricoid partial laryngectomy for non-squamous cell carcinoma of the larynx.

The objective of this paper was to evaluate the potential utility of supracricoid partial laryngectomies (SCPLS) for non-squamous cell carcinoma of the larynx. To illustrate our management of such tumours we present a case series based on six patients. Local control was achieved in five patients, with the sixth being salvaged by total laryngectomy and post-operative radiation therapy. Three of the six patients died of distant metastases. We concluded that supracricoid partial laryngectomies should become part of the armamentarium of the otolaryngologist - head and neck surgeon for non-squamous cell carcinoma of the larynx.

[Articulatory compensation after supracricoid partial laryngectomy with cricohyoidoepiglottopexy].

OBJECTIVES: The consequences of the modification of the glottis and the shortening of the vocal tract after supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) were investigated prospectively on ten patients. An acoustic analysis of the transfer function of the vocal tract was performed by measuring the formant frequencies of the [a] and [i] vowels. The articulation compensatory mechanisms of the vocal tract were observed with cinefluoroscopy in order to evaluate the phonation and articulation constraints. PATIENTS AND METHODS: Ten male patients were recorded before surgery and at six, 12 and 18 months after surgery. The results were compared with those of 10 male normal speakers having the same range of age. For the acoustic measures, we tracked the three first formant frequencies of the cardinal vowels [a] and [i], before and after surgery. Articulation investigation was performed with cinefluoroscopy for the vowels [a] and [i] uttered by two of the 10 patients. RESULTS: For the [a] vowel, the acoustic analysis showed higher values for all three formants, related to the shortening of the vocal tract after surgery. For the [i] vowel, the lowering of the second formant frequencies after surgery was related to an articulatory compensation. Cinefluoroscopy confirmed the shortening of the vocal tract, the tongue-root retraction for voicing and the anterior position of the tip of the tongue for the [i] vowel. CONCLUSIONS: The consequences of the shortening of the vocal tract after SCPL with CHEP can be evaluated, non invasively, by means of acoustic analysis. The understanding of the articulation compensatory mechanisms resulting from voicing constraints should help voice rehabilitation and improve oral communication in such patients.

Complications of postoperative radiation therapy after partial laryngectomy in supraglottic cancer: A long-term evaluation.

This retrospective study, based on a series of 90 patients with invasive squamous cell carcinoma of the supraglottis, was designed to document the functional outcome and complications after postoperative radiation therapy following partial laryngeal surgery. The surgical procedure was a standard supraglottic laryngectomy in 62 patients and a supracricoid partial laryngectomy in 28 patients. All of the patients had an unremarkable postoperative course and achieved locoregional control. The average dose delivered to the remaining larynx was 51.2 Gy (range 25-71 Gy). The average dose delivered to the neck was 50.6 Gy (range 22-70 Gy). The patients were treated at 180-cGy per fractions in a continuous course technique with a cobalt 60 beam. In 5 patients (5.5%) complications led to cessation of postoperative radiation therapy, and the total dose delivered to the remaining larynx and neck was less than 40 Gy. All patients were followed up for a minimum of 10 years or until death. The 5-, 10-, and 15-year actuarial survival estimates were 71. 5%, 44.3%, and 36.3%, respectively. The 5-, 10-, and 15-year actuarial severe complication estimates were all 11.2%. Overall, severe complications occurred in 15 patients. Severe complications led to death in 3 patients (3.3%), permanent gastrostomy in 3 (3.3%), and permanent tracheostomy in 1 (1.1%). A severe complication never resulted in completion of total laryngectomy. In univariate analysis, the mean dose delivered to the larynx was the only variable statistically related to the incidence of a severe complication. The mean dose delivered to the larynx was statistically higher (P = 0.014) in patients who had severe complications (60 Gy) than in patients who did not (50 Gy).

Aerodynamic and acoustic parameters in CO2 laser posterior transverse cordotomy for bilateral vocal fold paralysis.

The aim of this prospective study was to analyse airway improvement and acoustic and aerodynamic parameters after CO2 laser posterior transverse cordotomy (LPTC) in bilateral vocal fold paralysis (BVFP). Four patients (2 males, 2 females) were recorded pre- and post-operatively at 1, 3, 6, 12 and 24 months. Forced inspiratory volume during the first second (FIV), vital capacity, peakflow, and forced expiratory volume during the first second (FEV) were measured with the Gould II spirometer. Acoustic frequency features (average fundamental frequency, standard deviation, jitter, shimmer and harmonic-to-noise ratio) and speech duration parameters (maximum phonation time, number of words read per minute, and number of words per breath) were measured. Aerodynamic parameters were measured with the Aerophone II. Three tasks were completed. Pneumo-phonatory parameters in "maximum sustained phonation" and in "comfortable phonation", and laryngeal aerodynamic parameters (intraoral air pressure, oral airflow and sound pressure level) were measured non-invasively. Glottal resistance and vocal efficiency were calculated. FIV increased significantly after LPTC (p = 0.01). Postoperatively, frequency features were undetectable by standard commercialized algorithms. Acoustic and aerodynamic parameters improved in the measures obtained at the 6th postoperative month. These results were stable 2 years postoperatively in all cases. We conclude that laryngeal aerodynamic parameters can be used objectively to follow patients longitudinally after LPTC.

The role of partial laryngeal resection in current management of laryngeal cancer: a collective review.

A spectrum of treatment plans and surgical procedures is available for management of early and moderately advanced laryngeal cancer. While the approach of chemotherapy and irradiation, or irradiation alone, followed by total laryngectomy for failure is often employed in practice by present day clinicians, the options of conventional conservation surgery (CCS), transoral endoscopic laser surgery (TLS) and supracricoid partial laryngectomy (SCPL) provide a wide choice of treatments that may help attain the goal of cure with preservation of laryngeal function and integrity of the airway. While CCS has been supplanted for many early-stage lesions by TLS and for more advanced stages by SCPL, centres throughout the world have reported favourable results with CCS, which is often modified to include resection of more extensive tumours than was previously possible. During the past decade a number of extended CCS procedures have been developed for management of glottic tumours involving both vocal cords and the anterior commissure, the paraglottic space and with vocal cord fixation, and for supraglottic tumours involving the glottis or hypopharynx. TLS has proved an effective, minimally invasive and functionally satisfactory procedure for management of suitable T1 and T2 glottic cancers, and stage I-III supraglottic cancers. The procedure may be effectively employed in combination with neck dissection and postoperative radiotherapy when necessary, particularly for moderately advanced supraglottic carcinomas. SCPL has proven effective in management of glottic and supraglottic cancers of all stages, even with involvement of paraglottic space and thyroid cartilage, provided at least one arytenoid unit can be preserved with clear margins. Invasion of cricoid cartilage is the most significant limitation for this procedure. All three surgical approaches have been employed for irradiation failure, but with greatly increased failure and complication rates compared with the results of treatment of non-irradiated patients. Thus a decision to treat laryngeal cancer initially with irradiation may preclude a satisfactory result from partial laryngectomy should radiation fail. The treatment of laryngeal cancer should be individualized according to the size and extent of the tumour, the age and physical condition of the patient, and the skill and experience of the surgeon with various treatment modalities and surgical procedures.

Vertical partial laryngectomy versus supracricoid partial laryngectomy for selected carcinomas of the true vocal cord classified as T2N0.

From an inception cohort of 204 patients with squamous cell carcinoma of the true vocal cord classified as T2N0 and a minimum of 3 years of follow-up, the authors compare the oncological and functional outcomes following vertical partial laryngectomy (group 1; 85 patients) and supracricoid partial laryngectomy (group 2; 119 patients). The 10-year actuarial survival estimate was 46.2% for group 1 and 66.4% for group 2. Survival was statistically more likely to be reduced (p = .019) in group 1 than in group 2. The 10-year actuarial local control estimate was 69.3% for group 1 and 94.6% for group 2. Local recurrence was statistically more likely to occur (p < .0001) in group 1 than in group 2. Salvage treatment resulted in an overall 94.1% local control rate and a 78.1% laryngeal preservation rate for group 1 and an overall 99.2% local control rate and a 94.9% laryngeal preservation rate for group 2. The 10-year actuarial nodal control estimate was 81.7% for group 1 and 93.7% for group 2. Nodal recurrence was statistically more likely to occur (p = .028) in group 1 than in group 2. The 10-year actuarial estimate for patients without distant metastasis was 84.6% for group 1 and 95.1% for group 2. Distant metastasis was statistically more likely to occur (p = .05) in group 1 than in group 2. The hospital mortality rate was 1.2% for group 1 and 0.8% for group 2. The incidence of permanent gastrostomy was 0% for group 1 and 2.4% for group 2. The incidence of permanent tracheostomy was 1.2% for group 1 and 2.4% for group 2. The incidence of completion laryngectomy due to functional problems was 1.2% for group 1 and 0.8% for group 2.

Laryngeal stenosis after supracricoid partial laryngectomy.

The purpose of this study was to review the incidence, risks, management, and outcomes of nontumoral laryngeal stenosis after supracricoid partial laryngectomy (SCPL) in a case series of 376 consecutive SCPLs performed at 1 institution from 1975 to 1995 with a minimum of 3 years of follow-up. Post-SCPL nontumoral symptomatic laryngeal stenosis was defined as an inability to decannulate patients before the 60th postoperative day (group 1) or the development of dyspnea (in patients without local recurrence) after an initial period of prolonged, successful decannulation (group 2). Of 376 SCPLs performed, nontumoral symptomatic laryngeal stenosis developed in 14 (3.7%). There were 7 patients (1.85%) in group 1 and 7 patients (1.85%) in group 2. In univariate analysis, none of the following variables appeared to be statistically related to the risk of immediate stenosis (group 1): age, gender, comorbidity, diabetes mellitus, symptomatic gastroesophageal reflux, arteritis, preoperative radiotherapy, arytenoid cartilage disarticulation, type of reconstruction performed, and postoperative radiotherapy. A delayed laryngeal stenosis (group 2) was statistically more likely to occur if the reconstruction performed at the time of SCPL was a cricohyoidopexy (p = .01). Successful management of the laryngeal stenosis without permanent tracheostomy was achieved in 5 group 1 patients and 3 group 2 patients. We believe that stenosis in group I patients arose through technical error, whereas group 2 patients seemed to suffer from problems of healing, mainly cicatricial narrowing of the airway at the site of the cricohyoidal impaction, or pexis. As a result, whereas laryngeal stenosis in group 1 patients was usually more easily correctable through dilation, laser incision, or resection of redundant tissue or revision of the impaction, laryngeal stenosis in group 2 patients presented a more difficult and frustrating complication. The management and outcomes of these patients are presented.

p53 alterations predict tumor response to neoadjuvant chemotherapy in head and neck squamous cell carcinoma: a prospective series.

PURPOSE: The tumor suppressor gene p53 plays a crucial role in cell cycle control and apoptosis in response to DNA damages. p53 gene mutations and allelic losses at 17p are one of the most common genetic alterations in primary head and neck squamous cell carcinoma (HNSCC). Alterations of the p53 gene have been shown to contribute to carcinogenesis and drug resistance. PATIENTS AND METHODS: In this prospective series, patients with HNSCC were treated with cisplatin-fluorouracil neoadjuvant chemotherapy. p53 status was characterized in 106 patients with HNSCC (p53 mutations, allelic losses at p53 locus, and plasma anti-p53 antibodies) to determine the existence of a relationship between p53 gene status and response to neoadjuvant chemotherapy. RESULTS: Exons 4 to 9 of the p53 gene were analyzed, and mutations were found in 72 of 106 patients with HNSCC. p53 mutations were associated with loss of heterozygosity at chromosome 17p (P <.001). The prevalence of p53-mutated tumors was higher in the group of patients with nonresponse to neoadjuvant chemotherapy than in the group of responders (81% v 61%, respectively; P <.04). When compiling p53 mutations and anti-p53 antibodies in plasma, the correlation between p53 status and response to chemotherapy was significant (87% v 57%, respectively; P =.003). A multivariate analysis showed that p53 status is an independent predictive factor of response to chemotherapy. CONCLUSION: This prospective study suggests that p53 status may be a useful indicator of response to neoadjuvant chemotherapy in HNSCC.

[Swallowing disorders in unilateral recurrent laryngeal nerve paralysis].

Swallowing difficulties in isolated recurrent laryngeal nerve paralysis are rarely reported in the literature, although it is frequently mentioned in lesions of both recurrent laryngeal and superior laryngeal nerves. The aim of this prospective study was to evaluate the incidence of aspiration in patients with unilateral recurrent laryngeal nerve paralysis after head and neck or thoracic surgery. Eighteen patients were included and evaluated within the first week and eleven two months postoperatively. Position, tone and tension of the vocal fold as well as assessment of the glottic axis, arytenoid position and mobility, laryngeal sensibility, status of the pyriform sinus and salivary stasis were studied. Swallowing evaluation was performed using flexible fiberoptic videolaryngoscopy during dry swallowing, thick cream and methylene blue liquid swallowing. Five patients had symptomatic aspiration, one silent aspiration and twelve patients had no aspiration. The type of regimen feeding used was classified as a normal, mixed, or blended diet. Added specific treatment performed was also described. We conclude that aspiration may occur in unilateral recurrent laryngeal nerve paralysis and have to be systematically evaluated after pneumomectomy, because adequate treatment can be proposed.
