Abstract
Head and neck cancers are heavily infiltrated by immune cells, the significance of which is complex. The natural immune response against head and neck tumors, including anti-human papillomavirus (HPV) T cells, and humoral responses has been clearly documented. However, during the course of tumor progression, co-option of the immune system by tumor cells for their own advantage and increased resistance of tumor cells to immune attack also occur. Inflammation and immune subversion to support angiogenesis are key factors promoting tumor growth. Only a better understanding of this tumor-host interaction will permit a rational design of new immunotherapeutic approaches combining immunostimulation with drugs endowed with the ability to counteract immunoevasion mechanisms.

Abstract
OBJECTIVES We reviewed outcomes of treatment of early glottic carcinoma by transoral laser resection. METHODS We performed a retrospective study of tumor stage, type of cordectomy (European Laryngological Society), resection margins, local control, and laryngeal preservation. RESULTS Of 142 patients treated with curative intent, 79 (92% male; average age, 63 years) were retained for this study, on the basis of availability of information regarding resection margins, the absence of adjuvant radiotherapy, and followup of at least 2 years. The tumors were classified pTis (n = 21), pT1a (n = 51), or pT1b (n = 7) and were treated by cordectomy types I (23%), II (30%), III (27%), IV (6%), and V (14%). The average follow-up was 56 months (range, 24 to 150 months). The overall 5-year actuarial recurrence-free survival rate was 89%, and the 5-year actuarial disease-specific survival rate was 97.3%. There were 11 local recurrences (14%); 7 were treated by another laser resection, 1 by radiotherapy, 1 by supracricoid partial laryngectomy, and 2 by total laryngectomy. The overall rate of final local control with the laser alone was 100% for patients with initially positive margins, 95% for those with initially suspicious margins, and 94% for those with free margins. The overall rate of organ preservation was 100% for patients with positive or suspicious margins and 96% for those with free margins. Margin status (p = .39), cordectomy type (p = .67), and anterior commissure involvement (p = .16) were not statistically related to recurrence (Kaplan-Meier calculations with nonparametric univariate analysis). The recurrence rate was significantly higher for T1b tumors, however (p = .001). CONCLUSIONS Laser microresection provides high rates of local control and organ preservation for early glottic cancer. Positive or suspicious margins were not related to recurrence, nor was anterior commissure involvement. This study implies that suspicious margins can be managed with a "watch-and-wait" attitude. Re-treatment with laser, external partial laryngectomy, and radiotherapy remain therapeutic options for recurrences.

Abstract
Pain is very frequent in otolaryngology disease: headaches, facial pain, earaches, and neck pain. The search for nasal pathology with maxillary sinus, sphenoidal, or ethmoidal involvement is part of the workup for headache. Facial pain should first suggest symptomatic neuralgia through involvement of the cranial nerves - trigeminal, glossopharyngeal, superior laryngeal - even if asymptomatic neuralgia are the most frequent. Earaches should be investigated through a search for involvement of the ear at the pinna, the external acoustic conduit, and the tympanic membrane. If the ear examination is normal, pain irradiating from the masticatory apparatus, the parotid, or the oropharynx is undertaken, with a systematic search for a tumoral cause.

Abstract
In a series of 84 head and neck patients, a statistically significant correlation was observed between high serum soluble interleukin (IL)-2 receptor alpha (sIL-2Ralpha) (P = 0.034) and metalloproteinase-9 (MMP-9) concentrations (P = 0.036) at diagnosis and a shorter survival of these patients. As MMP-9 has been shown to mediate cleavage of IL-2Ralpha (CD25) by preactivated T cells, we looked for a relationship between MMP-9 expression and soluble IL-2Ralpha serum concentrations in these cancer patients. We did not find any correlation between intratumoral expression of MMP-9 or serum MMP-9 concentrations and serum sIL-2Ralpha levels. These results led us to reassess the role of MMP-9 in the release of sIL-2Ralpha. Treatment of Kit225 leukaemic cells with recombinant MMP-9 slightly decreased membrane CD25 expression and was associated with an increased concentration of sIL-2Ralpha in the supernatants. However, using a selective inhibitor of MMP-9 we did not succeed in specifically inhibiting the release of sIL-2Ralpha by the Kit225 cell line or by phytohaemagglutinin (PHA)-activated peripheral blood mononuclear cells. In addition, in a preclinical mouse model, basal serum sIL-2Ralpha concentrations and sIL-2Ralpha production by activated cells were not altered in MMP-9-deficient mice compared to wild-type mice. Interestingly, a broad spectrum metalloproteinase inhibitor inhibited the release of sIL-2Ralpha by PHA-activated peripheral blood mononuclear cells, suggesting that in contrast with current views concerning the major role of MMP-9 in the cleavage of membrane IL-2Ralpha, other proteases are involved in the shedding of sIL-2Ralpha. MMP-9 and sIL-2Ralpha appear therefore as independent prognostic markers in head and neck cancers.

Abstract
6039 Purpose: To determine the long-term oncologic outcomes for patients with squamous cell carcinoma (SCC) of the laryngopharynx treated with exclusive chemotherapy after complete clinical response to induction chemotherapy. Materials and Methods: After platin-based induction chemotherapy, selected patients with a complete clinical and histologic response were treated exclusively with additional chemotherapy and observed closely. The rates of overall survival, disease control, and organ preservation were calculated. Results: Survival at 1- and 5-years was 94.5% and 60.2%, respectively. Main causes of death were metachronous second primaries (27) and intercurrent disease (23) than local recurrence (10), distant metastasis, (9) and nodal recurrence (4). The 1-, 3- and 5- year Kaplan-Meier local control estimates were 73.5%, 53.3%, and 50.3%, respectively. No variable was associated with local recurrence using a multivariate analysis. Salvage treatment resulted in an observed final 85.6% local control rate and varied from 96% in patients with glottic cancer to 71% in patients with tumor originating from other locations. Overall, this treatment approach was well-tolerated: 30 patients (20%) experienced grade 3 toxicity; two patients (1.4%) had grade 4 toxicity events. Overall, chemotherapy allowed for successful modulation of local therapy in 66% of patients (96/146). Conclusions: For selected patients, exclusive chemotherapy does not significantly impact survival and maintains function in a majority of patients. Most remarkable, platin-based chemotherapy permitted us to modulate and to diminish the extent of local therapy. Future work should be directed to identify markers of response and resistance to identify which patients are best suited for this approach. No significant financial relationships to disclose.

Abstract
OBJECTIVES Endoscopic laser cordectomy is a minimally invasive surgical technique for Tis, T1 and selected T2 glottic carcinoma. The purpose of the study was to evaluate prospectively pre-operatively and 3 months after surgery i) acoustic and perceptual parameters, ii) quality of life through a self evaluation (VHI) test. METHODS A prospective longitudinal evaluation of 13 male patients, shared-out onto 3 surgical procedures (cordectomy type I, grouped type II and III, and type V). Patients were recorded before and at 1 and 3 months after surgery. The parameters recorded were; acoustic parameters (F0, Jitter, Shimmer), Maximum Phonation Time (MPT), perceptual evaluation using the GRBAS scale and the self evaluation scale with the Voice Handicap Index (VHI). RESULTS No statistics could be done because of the limited number of patients in each group. Perceptual and self evaluation data showed a favorable progression between 1 and 3 months for patients in group Type I, II and III cordectomy. Evolution of acoustic parameters is more difficult to analyze. The voice of the Cordectomy type V group remains whispery at 3 months after surgery. CONCLUSION The quality of voice is a very important criterion for the patients. During the first 3 months after laser cordectomy, the perceptual vocal function and the self evaluation improves. But for the acoustic data, 3 months is probably too short to objectively quantify an improvement especially after type V cordectomy.

Abstract
BACKGROUND Although the lateral pharyngotomy is a well-known surgical procedure, to our knowledge, no published reports have described the results achieved with a lateral pharyngectomy approach in patients with isolated and previously untreated selected invasive squamous cell carcinoma of the lateral wall of the pyriform sinus. METHODS The medical files and operative charts of 30 patients with an isolated, and previously untreated, squamous cell carcinoma of the pyriform sinus, treated for cure by lateral partial pharyngectomy and primary closure, as well as postoperative radiotherapy (n = 22), and preoperative chemotherapy (n = 8), were retrospectively studied. Sixteen tumors were classified as T1 and 14 as T2. All patients but one were followed until death. RESULTS Three patients (9%) died in the immediate postoperative period (two from medical complications and one from a surgery-related complication). Overall, 29 patients died, resulting in a 77.7%, 40%, 23.3%, and 15% 1-, 3-, 5- and 10-year Kaplan-Meier actuarial survival estimate, respectively. Only one patient had a serious postoperative complication develop. All patients were decannulated. No patients required a gastrostomy and/or completion total laryngectomy for functional reasons. Local recurrence occurred in four patients (13%). The 3-and 5-year Kaplan-Meier actuarial local control estimates were 88.5% and 79.6%, respectively. The use of a platin-based induction chemotherapy (p = .05) regimen was the only variable that was significantly statistically related to local recurrence. Overall, a 93.3% laryngeal preservation rate was achieved. CONCLUSION Partial pharyngectomy by means of the lateral pharyngotomy combined with postoperative radiation therapy is an efficient and function-sparing approach to control selected invasive squamous cell carcinomas of the lateral wall of the pyriform sinus.

Abstract
Organ preservation surgery is a reasonable name for these types of techniques because it accurately describes the postoperative outcome, which is preservation of the quintessential laryngeal functions: swallowing, respiration without a permanent stoma and speech. In response to the common use of total laryngectomy, the non-surgical approaches have often been referred to as organ preservation strategies. In many institutions, it appears that there are organ preservation strategies and then there is surgery. In our opinion there are both non surgical organ preservation strategies and surgical organ preservation strategies. The key is that in both approaches the goal is to spare the functions of the larynx. In both, the work-ups are very important to analyse 3-dimensional extent of the lesion by nasofibroscopy (laryngeal mobilities), endoscopy and radiology. Organ preservation surgical approach allowed to save the use of radiotherapy for the management of various metachronous second primary tumours.
