Function evaluation of laryngeal reconstruction using infrahyoid muscle after partial laryngectomy in 37patients.

Treatment of small laryngeal cancerous lesions (T1 and T2) is based on partial endoscopic or open surgery and radiotherapy. In addition to the oncological imperative, these techniques must optimally preserve the functions of breathing, swallowing and phonation. OBJECTIVE: To analyze the above functions in patients treated with supracricoid laryngectomy and reconstruction using infrahyoid muscle. MATERIALS AND METHODS: Breathing, swallowing and phonation were analyzed in 37patients treated in two institutes between 2005 and 2015. All patients undergoing the above type of reconstruction with a minimum 1year's follow-up were included. Respiratory study noted any tracheotomy and measured peak inspiratory flow. Preservation of cricoarytenoid units and nasogastric intubation time, and DHI-30 self-administered questionnaire results were collected to analyze swallowing function. Phonation was assessed on the VHI-30 self-administered questionnaire. RESULTS: The rate of primary surgery without tracheotomy was 64.9% (13patients), with rapid resumption of oral feeding (mean intubation time, 13days). Mean VHI score was 28.3 and mean DHI 30score 2.7. Mean peak inspiratory flow was 203.3mL/min. CONCLUSION: Supracricoid laryngectomy with reconstruction using subhyoid muscle is an alternative technique for the treatment of small laryngeal cancerous lesions, providing uncomplicated functional outcome.

Cervical lymph node metastases and T1 squamous cell carcinoma of the lips.

OBJECTIVE: The occurrence of cervical lymph node metastasis is a major prognostic factor for head and neck squamous cell carcinoma (SCC) of the lip. This study focuses on patients with T1 stage tumours,in order to describe the prevalence of metastatic lymphadenopathies. METHODS: A multicenter retrospective study was performed in three tertiary care referral centers and included 59 patients surgically treated for T1 stage SCC of the lips from January 1996 to December 2006. This surgical treatment concerned the tumour, with cervical neck dissection when lymph node metastasis was suspected. RESULTS: Cervical lymph node metastasis was found and histologically proven in 7 patients (11.9% of the cases, pN+ group; 95% confidence interval, 3.6 to 20.2%) during follow-up, never at the time of diagnosis. Metastasis appeared 13.3 ± 7.9 months (min. 5.3 months, max. 29.1 months) after the initial treatment and involved the IB level in all cases. Tumour progression was significantly longer in the pN+ group compared to patients with no lymph node metastases (sN-group). The pN+ group also had a significantly higher proportion of poorly or moderately differentiated tumours, and a significant decrease in overall survival, disease-free survival, and disease-specific survival. CONCLUSION: Lymph node metastasis occurs in roughly 12% of T1 stage SCC of the lips, and the management of neck lymph node areas is necessary. A randomized trial is needed to determine the proportion of occult lymph node metastases in T1N0 patients and the impact of this therapeutic procedure on survival.

Laryngeal preservation in ENT oncology. Retrospective series of 246 patients managed in the Caen University Hospital and François Baclesse Cancer Care Center between 1998 and 2008.

OBJECTIVES: A 10-year retrospective study investigated factors for survival and laryngeal preservation in advanced laryngeal, hypopharyngeal or epilaryngeal neoplasia. MATERIAL AND METHOD: Two hundred and forty-six patients with advanced cancer of the larynx (17.48%), hypopharynx (48.78%) or epilarynx (33.74%) undergoing primary organ-sparing treatment were included from 1998 to 2008. Treatment comprised chemotherapy followed by radiation therapy for 92.68% of patients, isolated radiation therapy for 1.6% and concomitant or sequential radiation-chemotherapy for 5.7%. General health status, history and tumor status were recorded. Factors influencing survival were analyzed by Kaplan-Meier estimator, log-rank test and Cox models. RESULTS: Median overall survival of the population was 2.3 years and median laryngeal preservation 0.99 years in male patients and 2 years in female patients. Survival correlated significantly with body mass index (BMI; P=0.0004), WHO performance status (P=0.0064), alcohol consumption (P=0.0004) and cessation (P<0.0001) and also T stage (P=0.0038), initial laryngeal mobility (P=0.0002) and post-chemotherapy assessment (P<0.0001). Survival with functional larynx correlated with baseline BMI at first consultation (P=0.016), baseline WHO grade (P=0.0005), laryngeal mobility (P<0.0001), T staging (P=0.0009), and T and/or N chemotherapy response to a classical organ preservation protocol (P<0.0001). CONCLUSION: Over and above established criteria, the present study highlighted the importance of general health and nutritional status during treatment.

Exclusive radiotherapy for stage T1-T2N0M0 lanryngeal cancer: retrospective study of 59 patients at CFB and CHU de Caen.

OBJECTIVE: Study of patients with stage T1N0M0 or T2N0M0 glottic cancer treated by exclusive radiotherapy and comparison of the survival and functional results of this series with those of the literature. METHOD: Retrospective study of stage T1N0M0 or T2N0M0 glottic cancers diagnosed between 1st January 2000 and 31st December 2010 and treated by exclusive radiotherapy. Evaluation of survival, recurrence and larynx preservation rates. STUDY CENTRES: CLCC François-Baclesse and CHU de Caen. PATIENTS: Fifty-nine patients (53 men and sixwomen) treated for glottic cancer (57 squamous cell carcinomas, two verrucous carcinomas) comprising 51 T1N0M0 and eight T2N0M0 tumours. Treatment with exclusive radiotherapy (mean dose of 70 Grays limited to the thyroid cartilage for 57 patients, with lymph node irradiation for two patients). RESULTS: In this series, five (9.8%) patients with stage T1N0M0 glottic cancer and three patients (37.5%) with stage T2N0M0 glottic cancer relapsed, corresponding to a global recurrence rate of 13.6%. Three of the eight recurrences involved lymph nodes exclusively (N), two patients relapsed exclusively at the primary tumour site (T) and three patients presented local and lymph node recurrence (T and N). Treatment consisted of salvage total laryngectomy with bilateral cervical lymph node dissection in three cases, bilateral cervical lymph node dissection and sensitized radiotherapy in two cases, exclusive chemotherapy in one case, cervical lymph node dissection and cervical radiotherapy in one case. The last patient with recurrence died prior to salvage therapy. The larynx preservation rate was 94.9%. CONCLUSION: In comparison with the literature, treatment of stage T1-T2N0M0 glottic cancer by exclusive radiotherapy gives very good results, with a larynx preservation rate of 95%.

Revascularized free scapular flaps in mandibular reconstruction. Report of 93 cases (April 1997 - October 2009).

OBJECTIVE: The aim of the present article is to demonstrate the relevance of revascularized free scapular flap in mandibular reconstruction in oncological cervicofacial salvage surgery. We will discuss the advantages and the disadvantages, indications and contraindications, together with possible complications and sequelae for this type of surgical flap. MATERIAL AND METHODS: Retrospective study of 93 revascularized free scapular flaps used to reconstruct segmental substance defects in the mandible from April 1997 to October 2009 (in 91 patients). All patients benefited from 10 months to 12 years follow-up surgical and functional results. Functional assessment following anatomic site restoration focused on the quality of feeding and deglutition. RESULTS: The anatomical success rate was 94.63% (5 complete necroses out of 93 flaps). Results were considered to be good (normal or close to normal function for feeding and deglutition) in the majority of patients (83% at 6 months, 91% at 18 months). On the donor site: Functional sequelae were moderate when post-operative reeducation was correctly performed. CONCLUSION: Vascularized free scapular flap bone graft is very interesting for the reconstruction of mandibular discontinuity, composite (soft tissue and cutaneous resection) or exclusively osseous defects (not in excess of 13 cm), secondary to oncologic or osteoradionecrotic resections.

[T1-T2 NO hypopharyngeal cancers treated with surgery alone. A GETTEC study (French Neck Study Group)]. / Cancers de l'hypopharynx T1-T2 "N0" traités par chirurgie exclusive. Etude GETTEC.

OBJECTIVE: Consider whether surgery alone in the treatment of early cancers of the hypopharynx can give identical or better results in terms of survival and local control than radiotherapy. METHODS: Forty-five patients were operated on during the years 1991-2004. Surgical treatment consisted in a resection by the transoral approach in four patients and 41 patients had a partial pharyngolaryngectomy. An elective neck dissection was performed on 43 patients. RESULTS: The 1-, 3-, and 5-year overall survival rates were 100, 95, and 75%. The 1-, 3-, and 5-year locoregional control rates were 93, 88, and 82% and were influenced by the presence of dysplasia on surgical margins (p=0.027). The oncological occurrences observed were five local recurrences, two nodal recurrences, ten second primary cancers, and two metastases. Five locoregional failures out of seven were controlled after a second treatment. CONCLUSION: Surgery alone gives completely satisfactory results in terms of survival and locoregional control. In case of recurrence, this makes it possible to operate on patients in nonirradiated areas with lower morbidity and mortality and better results. These results must be confirmed by a randomized trial.

[Interest of peri-operative immunonutrition in head and neck cancers]. / Intérêt de l'immunonutrition péri-opératoire en carcinologie cervico-faciale.

OBJECTIVE: Authors reported the results of a study on the application of immunonutrion in peri-operative (pre and postoperative) in head and neck cancer for all patients malnourished or not. In preoperative we used an oral treatmentand in postoperative an enteral one. MATERIALS AND METHODS: Prospective study concerning 78 patients (47 malnourished versus 31 not) having had heavy head and neck curative cancerology surgery. The mean follow up was of 10 months (from 7 to 16 month). They peri-operative immuno-enriched diet consisted, in pre-operative of 1000 kcal/j during 7 days of oral immunonutrition (Impact), and in post-operative, 1500 kcal/j during 10 days of enteral immunonutition (Crucial). The nutritional state was evaluated in pre-operative by simple clinical and biological parameters (size, weight, CMI "Corporal Mass Index", albumin, NRI "Nutritional Risk Index"), and in post-operative by the evolution of the weight and the CMI. The palatability of the product used in pre-operative and the patients' compliance to the treatment are studied using the satisfaction's multiple choice question paper. RESULTS: The study showed an improvement of the patients' nutritional and general state (regain appetite, less marked asthenia) and of the quality of life. The product used in preoperative was well tolerated, this oral supplementation led to the same beneficial effects of the enteral's. At eight days in preoperative, the average weight was 62.35 kg, the average CMI was 20.93, and the average NRI was 94.12. In post-operative the patients' nutritional state improved: at eight days, the average loss of weight was 2.82 kg, the average CMI was 22.2. At one and six months after respectively the average gain of weight was 2.17 kg and 6.11 kg, the average CMI was 23.71 and 25.16. The application of this protocol decreased the post-operative complications (13% reduction of the infectious complications and 6% diminution of the fistulas). The time of hospitalization is then reduced (1.7 days), and the life's longevity is improved. CONCLUSION: The results produced by this study, demonstrate the necessity to apply a peri-operative immuno-enriched diet systematically for all the patients with and without a degraded nutritional state, undergoing a heavy head and neck curative cancerology surgery.

[Laryngeal schwannoma: a case report and review of the literature]. / Schwannome laryngé: a propos d'un cas et revue de la littérature.

OBJECTIVES: In presenting a case of laryngeal schwannoma, the authors emphasize the difficulties in diagnosing this rare pathology and review treatment options. The recent literature concerning this benign tumour is reviewed. MATERIALS AND METHOD: The authors present a case of laryngeal schwannoma in a 29 year old man, revealed by exertional inspiratory dyspnea. RESULTS: The patient was treated by a conservative surgery with no recurrence after two years follow-up. CONCLUSION: CT scan and magnetic resonance imaging provide essentiel data on the spread of this benign tumour. The possibility of malignant change and recurrence warrant long-term follow-up.

[Lip, oral cavity and pharynx cancers in France: incidence, mortality and trends (period 1975-1995)]. / Les cancers de la lèvre, de la cavité buccale et du pharynx en France: incidence, mortalité et tendance (période 1975-1995).

With 10,882 estimated new cases in 1995 in France, lip, oral cavity and pharynx tumours rank 4th, representing 8.1% of all cancers in men. They are less frequent in women, with a sex ratio of 7. Based on the French cancer registries data which cover 13% of the metropolitan territory in 2000, both incidence and mortality increased until early 1980s to decrease thereafter. The main hypothesis proposed to explain the French leadership world-wide for these tumours deals with alcohol and tobacco consumption. Important differences observed between several areas within Europe, for some subsites, in connection with age or sex, are pointing toward the need of new studies about environment and/or genetics. Until now, comparisons between countries were made at the level of lip, oral cavity and pharynx category as a whole or by large subgroups. In this work we attempt to establish more accurate statistics, in order to comply with the situation of this cancer in France. Present results should encourage the scientific community to conduct site specific epidemiological studies.

[Voice rehabilitation with a voice prosthesis. Study of 62 patients with 5 years follow-up]. / Réhabilitation vocale par implant phonatoire. Etude de 62 patients ayant 5 ans de recul.

UNLABELLED: From December 1987 to February 1998, 270 patients underwent a total laryngectomy with voice restoration by a voice prosthesis. The analysis is focused on the 62 live patients with a 5 year follow-up. Tracheoesophageal speech had a success rate of 81% after 1 year and 73% after 5 years. The daily use of the voice prosthesis is only 68% after 1 year and 61% after 5 years. During the 5 year follow up (for all patients) 16 (26%) presented an enlarged fistula with leakage around the fistula and 17 (27%) needed a removal of the prosthesis. CONCLUSION: Tracheoesophageal speech with a voice prosthesis appears interesting for laryngectomized patients with: a high success rate, the quality and precocity of the voice obtained. However, it requires extensive care and the results deteriorate with time.

[Flow cytometry in ORL cancers]. / Cytométrie en flux dans les cancers ORL.

The possibility to perform flow cytometry was examined in a series of 167 patients with primary untreated head and neck carcinoma referred to our Institution from February 1989 to January 1992. In all cases, flow cytometry was carried out on frozen tumour samples. The Cox model was used including age, tumour size, nodal status on clinical assessment, topography, treatment, malignancy grade, S phase fraction and ploidy as independent variables and overall survival as dependent variable. In this study, ploidy could be assessed in only 73% of cases and S phase fraction and G2M in 65% of the population studied. No correlation could be evidenced between ploidy or SPF with other clinical, pathologic characteristics or clinical outcome. We conclude that flow cytometry should remain a research tool until the method has proved to be relevant in clinical routine, and until the yield of the technique can be improved.

[The value of extemporaneous study of the surgical margins of cancers of the upper aero-digestive tract. Apropos of 129 cases of oral and oropharyngeal tumors]. / Intérêt de l'étude extemporanée des limites d'exérèse dans les cancers des voies aéro-digestives supérieures (V.A.D.S.). A propos de 129 cas de tumeurs buccales et oro-pharyngées.

129 patients, who had oral cavity or oropharyngeal carcinoma underwent excision with intraoperative histopathologic examination. Thanks to this method, the number of satisfying resections has increased from 25% to 75%. Whatever the quality of the surgical excision may be, postoperative radiotherapy improves the prognosis.

[Prosthetic vocal rehabilitation of Herrmann's type after total laryngectomy. Results apropos of 29 cases]. / Réhabilitation vocale prothétique type Herrmann après laryngectomie totale. Résultats à propos de 29 cas.

The authors performed 29 surgical interventions of this type (24 primary and 5 secondary implantations). The treatment protocols, especially, the radio-chemotherapeutic protocols, were not changed and the radiotherapeutic tolerance of these prosthetic implants was particularly outstanding. This method may find wide application as well after single total laryngectomy as after circular total pharyngeal laryngectomy with restoration by gastric transplant. Speech is generally produced as early as the 12th day and we may assert that it is much better than esophageal speech, the whole indications and results being considered. These are being discussed and sustained support by the therapeutic team appears to be necessary.

[Screening for cancer of the upper aerodigestive tract in a high-risk population]. / Dépistage des cancers des V.A.D.S. dans une population à haut risque.

From the data collected in the Cancer Registry of Calvados, a screening program for neoplastic lesions of the whole upper digestive and respiratory tract was performed in a canton where esophageal cancer incidence is very high. 137 men underwent this examination for mouth, pharyngo-larynx and esophagus. None neoplastic lesion was revealed but histologic and cytologic swabs showed some abnormalities that are now being studied.

[Detection of buccal cavity cancers with toluidine blue (author's transl)]. / Le dépistage des cancers de la cavité buccale par le bleu de toluidine.

When malignant tumours of the oral cavity are of a small size, they are asymptomatic during a long time, and it is difficult to detect them. A method permitting to discover them more easily during the examination would be a precious rescue. In this aim, we have tested the oral coloration with toluidine-blue in 50 patients with a high risk of malignant tumour. This coloration has allowed to reveal cancer in 3 patients whereas no tumour was found at previous clinical examination.
