Oncological and Functional Outcomes of Larynx-preserving Surgery for Hypopharyngeal Cancer: A Comparison with Definitive Radiation-based Treatment. Cancer Res Treat 2021; 54:84-95. [PMID: 33781050 PMCID: PMC8756124 DOI: 10.4143/crt.2020.1197] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Accepted: 03/24/2021] [Indexed: 12/27/2022] Open
Abstract
Purpose Larynx-preserving surgery (LPS) have recently gained popularity and achieved comparable oncologic outcomes to conventional radical surgery for localized hypopharyngeal cancer (HPC). In the current study, the role of LPS has been assessed thoroughly in comparison with upfront radiation therapy (RT). Materials and Methods We retrospectively reviewed 185 candidates for LPS with cT1–2 disease; 59 patients underwent upfront LPS while 126 patients received upfront RT, respectively. Oncological and functional outcomes were investigated and compared. Results Following LPS, safe margin (≥ 5 mm) was achieved in 37.3% of patients. Overall, better clinical outcomes at 5 years were achieved following upfront LPS than those following upfront RT: overall survival (OS) (72.7% vs. 59.0%, p=0.045), disease-free survival (DFS) (59.8% vs. 45.0%, p=0.039), and functional laryngeal preservation (100% vs. 89.7%, p=0.010). Although similar outcomes were observed in patients with cT1 disease, better 5-year DFS was achieved following upfront LPS in patients with cT2 disease (57.0% vs. 36.4%, p=0.023) by virtue of better local control. Despite frequent cN2–3 disease in upfront LPS group, comparable outcomes were observed between upfront RT and LPS group. However, multivariable analyses revealed that performance status and double primary cancer diagnosed within 6 months of HPC diagnosis affected OS significantly, while treatment modality per se did not. Conclusion Although upfront LPS could provide better local control than upfront RT in patients with cT2 disease, overall outcomes were comparable following either modality. Treatment selection of larynx-preserving approach for HPC should be individualized based on tumor and patient factors.

Abstract
OBJECTIVE Due to the current coronavirus disease 2019 (COVID-19) pandemic, otolaryngologists face novel challenges when treating patients with head and neck cancer. The purpose of this review is to evaluate the current evidence surrounding the treatment of these patients during this pandemic and to provide evidence-based recommendations with attention to increased risk in this setting. DATA SOURCES A review of the literature was performed with PubMed. Because recently published articles on this topic may not yet be indexed into PubMed, otolaryngology journals were hand searched for relevant articles. Guidelines from national organizations were reviewed to identify additional relevant sources of information. REVIEW METHODS Two groups of search terms were created: one with terms related to COVID-19 and another with terms related to head and neck cancer and its management. Searches were performed of all terms in each group as well as combinations of terms between groups. Searches and subsequent exclusion of articles were performed in accordance with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Additional articles were identified after relevant journals and guidelines from national organizations were reviewed. CONCLUSIONS Patients with head and neck mucosal malignancy require continued treatment despite the current pandemic state. Care must be taken at all stages of treatment to minimize the risk to patients and health care workers while maintaining focus on minimizing use of limited resources. IMPLICATIONS FOR PRACTICE Patient care plans should be guided by best available evidence to optimize outcomes while maintaining a safe environment in the setting of this pandemic.

Abstract
BACKGROUND Surgical treatment of cancers that arise from or invade the hypopharynx presents major reconstructive challenges. Reconstructive failure exposes the airway and neck vessels to digestive contents. METHODS We performed a national N = near-all analysis of the administrative dataset to identify pharyngolaryngectomies in England between 2002 and 2012. Information about morbidity, pharyngeal closure method and post-operative complications was derived. RESULTS There were 1589 predominantly male (78%) patients whose mean age at surgery was 62 years. The commonest morbidities were hypertension (24%) and ischemic heart disease (11%). For 232 (15%) patients, pharyngolaryngectomy was performed during an emergency admission. The pharynx was closed primarily in 551 patients, with skin or muscle free or pedicled flaps in 755 patients and with jejunum and gastric pull-up in 123 and 160 patients, respectively. In-hospital mortality rate was 6% and was significantly higher in the gastric pull-up group (11%). Reconstructive failure had an odds ratio of 6.2 [95% confidence interval (CI) 2.4-16.1] for in-hospital death. The five-year survival was 57% and age, morbidities, emergency surgery, gastric pull-up, major acute cardiovascular events, renal failure and reconstructive failure independently worsened prognosis. Patients who underwent pharyngeal reconstruction with radial forearm or anterolateral thigh flaps had lower mortality rates than patients who had jejunum flap reconstruction (hazard ratio = 1.50 [95% CI 1.03-2.19]) or gastric pull-up (hazard ratio = 1.92 [95% CI 1.32-2.80]). CONCLUSIONS Pharyngolaryngectomy carries a high degree of risk of morbidity and mortality. Reconstructive failure worsens short- and long-term prognosis, and the use of cutaneous free flaps appears to improve survival.

Pyriform sinus squamous cell carcinoma: oncological outcomes in good responders of induction chemotherapy-based larynx preservation protocols. Eur Arch Otorhinolaryngol 2014; 272:1725-31.

Abstract
Induction chemotherapy-based larynx preservation protocols use chemotherapy to select exclusively patients with 'chemosensitive' tumors for a nonsurgical treatment with radiation therapy. This study on pyriform sinus squamous cell carcinoma (SCC) is interested in the oncological outcome of treatment based on radiation therapy when offered to patients with tumors responding to induction chemotherapy. This was a retrospective cohort study. The cohort included good responders to induction chemotherapy, subsequently treated with definite radiation therapy (with or without concomitant chemotherapy) for pyriform sinus SCC, in a tertiary referral cancer center. The primary endpoints were overall, laryngectomy-free and disease-free survival and the secondary endpoints were analysis of treatment failures and possibilities of salvage treatment. Forty-two patients fulfilled the inclusion criteria and were retained for analysis; 7% were stage II (3/42), 48% stage III (20/42) and 45% stage IV (19/42). At 1, 3 and 5 years, the overall survival was 95% (40/42), 74% (31/42), and 60% (SE ≈ 0.08), respectively. For the same intervals, the laryngectomy-free survival was 90% (38/42), 69% (29/42) and 50% (SE ≈ 0.08), respectively. The estimated 5-year disease-free survival was also 50%. Disease-free survival was significantly better for N0 patients. There was a 28% recurrence rate, mainly in the primary tumor site (9/11), with or without simultaneous nodal recurrence. Interestingly, more than one-third of all oncologic failures occurred beyond the first 3 years of follow-up. Salvage treatment was not possible or definitely inefficient in at least 2/3 of all recurrences. In candidates for larynx preservation for a pyriform sinus SCC, good response to induction chemotherapy followed by definite radiation therapy seems to be associated with a more favorable prognosis. Nevertheless, in case of locoregional recurrence the possibilities for efficient salvage treatment are limited.

Abstract
PURPOSE OF REVIEW This review aims at unravelling the medical literature which has reported on the treatment of 'larynx preserving' chemoradiotherapy strategies and separating the treatment sites, larynx and hypopharynx, from each other and reporting on the adverse effects and functional outcomes of patients with hypopharyngeal cancer. RECENT FINDINGS The literature reports on the treatment of advanced laryngeal and hypopharyngeal cancer with chemoradiotherapy together as a 'common cancer site'. Although the chemotherapeutic drugs affect the tumour and the normal tissues similarly in both the larynx and hypopharynx, their effects on the patient groups are different, mainly affecting swallow, airway protection mechanisms and voice/speech to a greater or lesser extent. Pretreatment symptoms and function should be documented subjectively and objectively prior to commencing nonsurgical treatment. Hypopharyngeal cancer should be reported separately, and preferably stratified into the three subsites, according to the T stage of disease rather than TNM stage. Equipment for such testing and the process for such documentation are available in most clinical areas, worldwide. SUMMARY Future analysis relies on the conscientious monitoring of adverse effects of all treatment modalities and an assessment of function as well as quality of life impact on the patient. Thus, the specialty can make informed decisions on the most appropriate and most suitable mode of treatment for individual patients based upon their tumour, their preoperative organ function, their likely future organ function and the likelihood of cure.

Abstract
PURPOSE Cis-platinum and radiation in combination are current organ preservation treatment strategies for head and neck cancer. Their individual ototoxicity has been investigated, with recent demonstration of ototoxicity in clinical studies. Currently, no ototoxicity studies have been performed in animals receiving similar schedules of radiation or cis-platinum to those patients with head and neck cancer. MATERIALS AND METHODS In the present study, an animal model was developed to investigate the effects of combined modality therapy on hearing. Albino guinea pigs were given equivalent protocol dosages of cis-platinum (3 parenteral courses), fractionated radiation (25 fractions over 5 weeks), or both. Click and tone burst auditory brainstem response (ABR) measurements were performed before and 6 weeks after the completion of treatment. RESULTS Animals receiving radiation or cis-platinum and radiation experienced permanent significant ABR shifts at all frequencies, with 33% of the animals experiencing complete unilateral sensorineural hearing loss at 2 or more frequencies in the ear receiving the full radiation dose (7075 cGy over 25 fractions) (P < .05, paired t test analysis). The animals receiving 3 doses of cis-platinum had no significant ABR threshold shifts at 6 weeks. These data suggest that cis-platinum and radiation cause greater ototoxicity than cis-platinum alone. These findings correlate closely with sensorineural hearing loss in combined modality patients at our institution and in recent studies. CONCLUSIONS We conclude that the current animal results parallel those seen clinically and serve as a model for ototoxicity from combined modality therapies in future protocols.

Abstract
OBJECTIVE To evaluate the advantage of accelerated fractionation radiotherapy for patients with hypopharyngeal cancer requiring total laryngectomy. METHODS Seventy patients with previously untreated, technically resectable hypopharyngeal cancer who received larynx-preserving treatment with radiotherapy between April 1992 and June 2004 were analyzed. No patients had previous history of other malignancy or poor performance status that would possibly affect the outcomes. A total RT dose of > or = 60 Gy/6 weeks was determined depending on the tumor clearance during treatment before December 1998, and fixed to 70 Gy in all patients thereafter. Accelerated fractionation (70 Gy/<49 days) was completed in 35 patients during the latter period. Concomitant platinum-based chemotherapy was used in 41 patients after May 1998. RESULTS Local control rates at 2 years were 72 and 68% for patients with T2 and T3/T4 disease, respectively. Patients who had received 70 Gy/<49 days achieved a better local control rate than those who had received other, more conservative total dose/overall treatment time with statistical significance (91% versus 50% at 2 years, P < 0.001). Multivariate analysis involving 70 Gy/<49 days of radiotherapy, T-classification (T2 versus T3/4), and use of chemotherapy revealed that administering 70 Gy/<7 weeks was the only independent prognostic factor (P = 0.007) for better local control. CONCLUSIONS Our experience in radiotherapy for hypopharyngeal cancer mirrored the results of previously conducted large randomized trials for various head and neck cancers. Encouraging local control in this study warrants prospective study to test the long-term oncological and functional outcome of larynx-preserving treatment in patients with advanced but resectable volume of this disease.

Abstract
Since the first total laryngectomy was undertaken, efforts have been made to avoid removing the entire larynx. For a long time, partial surgery and radiotherapy were the only options that could preserve the larynx. Development of active chemotherapy regimens has prompted an era of intensive clinical research. Induction chemotherapy followed by radiotherapy in patients with objective responses has been shown to allow conservation of the larynx in nearly two-thirds of individuals, without any effect on survival; concurrent chemoradiotherapy also provides high rates of laryngeal preservation, again without affecting survival; and induction chemotherapy followed by concurrent chemoradiotherapy is under investigation. In the meantime, partial open surgery and endoscopic carbon dioxide laser procedures are feasible in selected moderately advanced laryngopharyngeal cancers as an alternative to destructive surgery. Altered fractionation radiotherapy can also be used in management of these tumours, and targeted treatments have opened a new area of clinical research. Findings of basic research and modern imaging should provide useful approaches for selection of patients for various strategies.

Abstract
PURPOSE There has been no definitive randomized study to identify the optimal therapeutic regimen for treating squamous cell carcinoma of tonsil. The purpose of this study was to retrospectively evaluate the treatment outcome according to various combinations of surgery, radiation therapy and chemotherapy. MATERIALS AND METHODS Fifty-six patients with tonsillar carcinoma, who were treated at Seoul National University Hospital from March 1985 to August 2001, were the subjects of this study. Twenty-one patients received surgery followed by radiation therapy (SRT), 16 patients underwent radiation therapy alone (RT), and 19 patients received neoadjuvant chemotherapy and radiation therapy (CRT). The median radiation dose was 66.6 Gy for the SRT group and 70.2 Gy for the RT and CRT groups. Surgery comprised extended tonsillectomy and modified radical neck dissection of the involved neck. Cisplatin and 5-fluorouracil were used every three weeks for 3 cycles in the SRT group. The median follow-up was 73.2 months. RESULTS The distribution of T-stage was 4 cases of T1, 14 cases of T2, 1 case of T3 and 2 cases of T4 staging in the SRT group, 2 cases of T1, 6 cases of T2, 5 cases of T3 and 3 cases of T4 staging in the RT group and 0 cases of T1, 7 cases of T2, 9 cases of T3 and 3 cases of T4 staging in the CRT group. The distribution of N-stage was 5 cases of N0, 2 cases of N1, 13 cases of N2 and 1 case of N3 staging in the SRT group, 6 cases of N0, 5 cases of N1, 5 cases of N2 and 0 cases of N3 staging in the RT group, and 2 cases of N0, and 7 cases of N1, 9 cases of N2 and 1 case of N3 staging in the CRT group. The five-year overall survival rate (OSR) for all patients was 78%. The five-year OSR was 80% for the SRT group, 71% for the RT group, and 80% for the CRT group (p=ns). The five-year disease-free survival rate was 93% for the CRT group and 71% for the RT group (p=0.017). Four patients developed local failure and one patient failed at a regional site in the RT group, and one patient failed at a primary site in the CRT group. The five-year DFS was 84% for patients who had undergone neck dissection and 76% for patients who had not undergone neck dissection (p=ns). Treatment-related complications of grade 3 or 4 occurred in 15 patients, and the incidence of complication was not different between each of the treatment methods. CONCLUSION Although the patients with more advanced T stage were included in the RT and CRT groups, the OSR was not statistically different according to the treatment methods. In the radical radiation therapy group, the addition of neoadjuvant chemotherapy showed an improvement in the disease-free survival. Because of the retrospective nature of our study and the small number of patients, this study cannot draw any definite conclusions, but it suggests that radiation therapy with chemotherapy can be a good alternative option for squamous cell carcinoma of tonsil. Controlled randomized study is necessary to confirm this hypothesis.

Abstract
The aim of this study is to evaluate the results of treatment for hypopharyngeal cancer and indicate the future prospect of the treatment. Seventy-four patients with squamous cell carcinoma of the hypopharynx admitted to Miyagi Cancer Center from 1993 through 2000 are reviewed. Sixty-four patients received radical treatment, and 10 patients received palliative treatment or no treatment. The cancer was advanced (stages III and IV) in 82% of all the patients. The overall 5-year survival rate of all the patients was 38%. The overall 5-year survival rate of 64 patients received radical treatment was 43%. The ten patients who received palliative treatment or no treatment died of cancer within 16 months. Fifty-two out of the 74 patients underwent neck dissection for the neck lymph node involvement; forty of the 52 patients underwent ipsilateral neck dissection and 12 underwent bilateral neck dissection. Four out of the 40 patients, who underwent ipsilateral neck dissection alone, developed late contralateral regional recurrence but were successfully treated by contralateral neck dissection at the time of recurrence. Twenty-three out of 74 patients had multiple primary cancers synchronously or metachronously (31%). Cause of the death of six patients out of 74 patients was confirmed to be primary cancers other than hypopharyngeal cancer, as judged by physicians in other department or other hospitals. Most of the patients died due to distant metastasis from hypopharyngeal cancer or other primary cancers. We therefore conclude that contralateral elective neck dissection which is frequently chosen for the treatment of hypopharyngeal cancer surgery is unnecessary. Even if locoregional control is accomplished, distant metastasis or multiple primary cancers emerge and make prognosis poor. To improve the prognosis, we should develop some strategy against hypopharyngeal cancer for each patient. New strategies including chemoprevention and surgery against distant metasistasis are necessary.

BACKGROUND Radical surgery followed by radiotherapy plays an important role in the treatment of patients with hypopharyngeal cancer. However, there is no general consensus as to which is the best method of reconstruction after surgical resection. METHODS We retrospectively reviewed the records of 91 patients who underwent radical surgery and reconstruction. Postoperative complications and oncologic results of the different reconstructive methods were compared. RESULTS Reconstruction with gastric pull-up had the lowest pharyngocutaneous (PC) fistula (0%) and pharyngoesophageal (PE) stenosis rates (0%). However, the overall postoperative complication rate was high (64%). Laryngotracheal flap (LTF) reconstruction had relatively lower rates of PC fistula (3%), PE stenosis (10%), and overall complications (22%). The introduction of the LTF technique significantly decreased postoperative complications from 71% to 30% (p = .0001), with similar tumor control and survival. CONCLUSIONS Hypopharyngeal reconstruction with an LTF is a simple and effective method. The chance of using a complex flap is decreased. The postoperative complications are reduced, and the oncologic results are satisfactory.

Abstract
Knowing the surgical options for treating laryngeal carcinomas and the factors that are used to select patients for radiation therapy leads to a more valuable and relevant interpretation of neck scans in patients with laryngeal tumors. Critical factors include tumor volume; cartilaginous invasion; spread across supraglottic-glottic-subglottic boundaries; infiltration of preepiglottic, paraglottic, and pharyngeal planes; and nodal disease. MR imaging offers greater sensitivity to cartilaginous invasion than CT but shows a higher rate of false-positive studies. Direct coronal MR imaging is often valuable in assessing these issues.

Abstract
Concomitant chemoradiotherapy is the most effective treatment of unresectable head and neck cancer. Docetaxel and carboplatin are two active drugs that potentiate radiotherapy. Thirty patients (median age = 56 years; median Eastern Cooperative Oncology Group performance status = 1) received radiotherapy (70 Gy, 2 Gy/d, 5 d/wk) concurrent with carboplatin AUC 0.3 to 0.5 on day 1-5, weeks 1, 3, 5, 7, and docetaxel 15 to 25 mg/m2 on day 4 of weeks 2, 4, and 6. Site of unresectable squamous cell carcinoma was as follows: oropharynx, 41%; hypopharynx, 27%; oral cavity, 16%; and larynx, 16%. Stage was III in 13% and IV in 87%. In 11 patients, pharmacokinetic parameters were evaluated. Acute G4 toxicity was as follows: neutropenia, 20%; mucositis, 33%. We had the following acute G3 toxicities: mucositis, 40%; neutropenia, 37%; dermatitis, 23%; and anemia, 13%. The maximum tolerated dosage was area under the curve 0.5 for carboplatin and 20 mg/m2 for docetaxel. Median radiotherapy dose was 69 Gy, and 175 out of 210 courses (83%) were administered. At the end of the treatment, we had 20 complete responses (CR) (67%), 9 partial responses (30%), and 1 no change (3%). After radial neck dissection, 2 patients achieved a CR (overall CR = 73%). After a median follow-up of 2.5 years, we had a 3-year local progression-free survival of 85%, failure-free survival of 69%, and overall survival of 60%. A significant increase of Cmax of carboplatin concentration was noted at the beginning of weeks 3, 5, and 7. Total plasma platinum raises during each course of 5 days of carboplatin without reaching a steady state. Carboplatin, docetaxel, and concomitant conventional radiotherapy is a feasible and effective treatment of unresectable head and neck cancer. The concurrent administration of two drugs does not alter pharmacokinetic drug behavior compared with single-agent data.

Abstract
OBJECTIVE A survey was undertaken to document the clinical management of T3 and T4 pure glottic primary carcinomas and the management of the N0 neck by otolaryngologists and radiation oncologists. STUDY DESIGN AND SETTING This study represents the results of a national survey of 250 otolaryngologists and 250 radiation oncologists regarding management of T3 N0 M0 and T4 N0 M0 glottic carcinomas. RESULTS Of the surveys sent, 208 completed questionnaires were received. Results of this survey suggest that 87% and 90% will treat the neck for a T3 N0 M0 and T4 N0 M0 glottic tumor, respectively, with a large number choosing to perform a radical neck dissection. CONCLUSIONS A significant percentage of otolaryngologists perform neck dissections in the management of T3 N0 M0 and T4 N0 M0 glottic carcinomas. Given the relatively low risk of occult metastasis, potentially high morbidity associated with overtreatment, and the lack of a well-designed outcome study investigating treatment alternatives, a prospective randomized study is needed to address the issue.

Abstract
BACKGROUND Hypopharyngeal cancer often presents at an advanced stage. Radical surgery has played an important role in the treatment of these cases; however, it always results in a large, or even a circumferential, defect of the pharyngoesophageal segment (PES) that causes some difficulties during reconstruction. MATERIALS AND METHODS Twelve patients with advanced hypopharyngeal cancer and cervical esophageal invasion received surgery resulting in a circumferential defect of PES, which was reconstructed with the contralateral unaffected laryngotracheal flap and a patch-on pectoralis major myocutaneous flap (PMMCF). RESULTS The operation time of this method was shorter compared with free flap reconstruction. Only two minor complications and no pharyngocutaneous fistulas were found postoperatively. Nine patients can resume a regular diet. During the follow-up period (median, 38 months), there were no local recurrences and only one contralateral neck recurrence. CONCLUSIONS The preliminary result shows this technique is a simple and effective method with low morbidity and satisfactory oncologic and functional results.

Abstract
Organ-preservation strategies include definitive radiation therapy alone, induction chemotherapy followed by radiotherapy, and concurrent chemoradiotherapy. Over the past decade, induction chemotherapy followed by radiotherapy has been the standard for the nonsurgical management of advanced laryngeal cancer. Over this same period, however, other nonsurgical strategies have been under evaluation. These approaches include radiotherapy with concurrent chemotherapy to take advantage of the radiosensitizing properties of most cytotoxic drugs with activity against squamous cell cancer, altered fractionation radiotherapy, and the incorporation of molecularly targeted therapeutics into multimodality treatment.

Abstract
Knowing the surgical options for treating laryngeal carcinomas and the factors that are used to select patients for radiation therapy leads to a more comprehensive interpretation of neck scans in patients with laryngeal tumors (Table 6). Critical factors include tumor volume; cartilaginous invasion; spread across supraglottic-glottic-subglottic [table: see text] boundaries; infiltration of preepiglottic, paraglottic, and pharyngeal planes; and nodal disease. MR imaging offers greater sensitivity to cartilaginous invasion than CT but leads to a high rate of false-positive studies, which decreases its overall accuracy. Thin-section CT with multiplanar capability is competitive with direct coronal MR scanning and benefits from high specificity and submillimeter section thickness, if multidetector units are employed. Overall, the head and neck radiologist plays an invaluable role in assessing the extent of disease and therefore influences the appropriate selection from the available treatment options.

Abstract
BACKGROUND The treatment of patients with squamous cell carcinoma (SCC) of the oropharynx remains controversial. No randomized trial has addressed adequately the question of whether surgery (S), radiation therapy (RT), or combined treatment is most effective. METHODS Treatment results from North American academic institutions that used S with or without adjuvant RT (S +/- RT) or used RT alone or followed by neck dissection (RT +/- ND) for patients with SCC of the tonsillar region or the base of tongue were compiled through a MEDLINE search (from 1970 to August, 2000) and from the references cited in each report. Studies were eligible for inclusion if they contained direct, actuarial (life-table), or Kaplan-Meier calculations for the following end points: local control, local-regional control, 5-year absolute survival, 5-year cause specific survival, or severe or fatal treatment complications. Weighted average results, which took into account series size, were calculated for each end point for the purposes of treatment comparison. Results and conclusions were based on data from 51 reported series, representing the treatment of approximately 6400 patients from the United States and Canada. RESULTS The results for patients with SCC of the base of tongue who underwent S +/- RT versus RT +/- ND, respectively, were as follows: local control, 79% versus 76% (P = 0.087); local-regional control, 60% versus 69% (P = 0.009); 5-year survival, 49% versus 52% (P = 0.2); 5-year cause specific survival, 62% versus 63% (P = 0.4); severe complications, 32% versus 3.8% (P < 0.001); and fatal complications, 3.5% versus 0.4% (P < 0.001). The results for patients with SCC in the tonsillar region who underwent S +/- RT versus RT +/- ND, respectively, were as follows: local control, 70% versus 68% (P = 0.2); local-regional control, 65% versus 69% (P = 0.1); 5-year survival, 47% versus 43% (P = 0.2); 5-year cause specific survival, 57% versus 59% (P = 0.3); severe complications, 23% versus 6% (P < 0.001); and fatal complications, 3.2% versus 0.8% (P < 0.001). CONCLUSIONS The information in this article provides a useful benchmark for evidence-based counseling of patients with SCC of the oropharynx. The rates of local control, local-regional control, 5-year survival, and 5-year cause specific survival were similar for patients who underwent S +/- RT or RT +/- ND, whereas the rates of severe or fatal complications were significantly greater for the S +/- RT group. Furthermore, available data on the functional consequences of treatment suggest the superiority of RT +/- ND. The authors conclude that RT +/- ND is preferable for the majority of patients with SCC of the oropharynx.

Abstract
PURPOSE To determine the feasibility of an organ preservation regimen consisting of infusional paclitaxel administered concurrently with radiotherapy to patients with locally advanced head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS Thirty-three previously untreated patients with stage III or IV tumors were enrolled onto the study. Paclitaxel was administered as a 120-hour continuous infusion every 3 weeks during the course of radiation therapy. Sixteen patients received a paclitaxel dose of 105 mg/m(2), and 17 patients received 120 mg/m(2). Radiation was delivered in a standard format at 1.8 Gy/d to a total dose of 70.2 to 72 Gy. RESULTS Three months after therapy, a 76% complete response (CR) at the primary site and a 70% overall CR was achieved. At 36 months, locoregional control was 55.7%, overall survival was 57.8%, and disease-free survival was 51.1%. The median survival duration for all 33 patients was greater than 50 months at the time of this report. Local toxicities including mucositis, dysphagia, and skin reactions were severe but tolerable. All patients retained functional speech, and all but four patients were swallowing food 3 months after treatment. Steady-state plasma concentrations for paclitaxel were not achieved during a 120-hour infusion, suggesting a nonlinear process. Tumor volume quantified by pretreatment computerized tomography imaging was associated with likelihood of response and survival. CONCLUSION Paclitaxel administered as a 120-hour continuous infusion in combination with radiotherapy is a feasible and promising treatment for patients with advanced HNSCC.

Abstract
BACKGROUND Occasionally in head and neck cancer patients treated surgically after induction chemotherapy, the histologic analysis of the excised tissue does not show evidence of viable tumor cells, a situation that the authors named "negative specimen." The objective of this study was to quantify the frequency of negative specimens in surgery after induction chemotherapy and to analyze the repercussions of this situation. METHODS A retrospective study of prospectively collected data on 245 patients treated surgically after induction chemotherapy was made to calculate the frequency of negative specimens. An individualized review of the patients with negative specimens was made. The actuarial survival was calculated in relation to the existence of residual tumor. RESULTS Twenty-five patients (10%) had negative specimens. Five-year adjusted survival for patients with negative specimens was 96%, significantly better than 62% survival in patients with residual tumor. CONCLUSIONS Ten percent of patients treated surgically after induction chemotherapy had no residual tumor. These patients had a favorable prognosis.

Abstract
The management of advanced cancers of the larynx and hypopharynx has become increasingly complex as different treatment modalities, including surgery, radiation, and chemotherapy, have been combined with the goal of improving local disease control and disease-specific survival. A union of 17 comprehensive cancer centers in the United States, the National Comprehensive Care Network (NCCN), was formed in 1995 to promote state-of-the-art cancer care. To achieve this goal, multidisciplinary panels of experts from member institutions have created disease-specific practice guidelines for the evaluation and treatment of cancer patients, including those with head and neck cancers. Although detailed analysis of surgical methods and radiation techniques are beyond the scope of this article, the evolving laryngeal preservation strategies for patients with advanced, resectable hypopharyngeal or laryngeal (including supraglottic and glottic) cancers are reviewed using relevant sections of the NCCN practice guidelines as a framework for discussion.

Abstract
Although there is no definite survival advantage to the use of sequential induction chemotherapy (CT) followed by radiotherapy (RT) in advanced resectable laryngeal cancer, this approach does succeed in preserving the larynx in many of these patients. The authors performed this study to analyze their results using a similar approach for patients with advanced resectable cancer located outside the larynx who would have required a total laryngectomy for oncologic or functional reasons. A retrospective study was performed at a single institution that included all patients with advanced resectable nonlaryngeal head and neck cancer treated with induction CT between January 1990 and August 1995. A total of 19 patients were included, with primary cancers located in the oropharynx in 14 patients, the hypopharynx in four, and the oral cavity and oropharynx in one. Eight patients had clinical stage III disease, and 11 patients had stage IV disease. Our treatment protocol consisted of two cycles of induction CT with cisplatin and 5-fluorouracil, followed by a third cycle of CT and subsequent RT in patients who achieved at least a clinical partial response (PR) after two courses of induction CT. Eighteen of 19 patients were evaluable for response. Overall, 13 patients (72%) had a major response (PR or CR) to induction CT at the primary site, and eight patients (57%) had a major response to chemotherapy in the neck. With a mean follow-up of 53 months (range, 24-71 months), the disease-specific survival was 57% for those patients with cancer of the oropharynx and oral cavity. In the subset of patients with hypopharynx cancer, 3 of 4 patients died of cancer despite achieving major response to induction CT. Organ preservation using sequential CT and RT for advanced resectable nonlaryngeal head and neck cancer is feasible, and the results in our experience with cancer of the oropharynx were similar to those reported for primary laryngeal cancer. Our limited experience using this protocol for cancer of the hypopharynx has been disappointing.

Abstract
OBJECTIVES Compare the most commonly used types of tracheoesophageal voice prostheses, Blom Singer and Provox. STUDY DESIGN Prospective study of 113 prostheses placed in 52 patients randomly selected to receive Blom-Singer and Provox. METHODS Postoperative voice was recorded at 1 and 4 months after valve placement. Survival time of the prosthesis and four objective voice parameters were analyzed. Eight judges rated all recordings in a random order for six subjective voice parameters. Subgroup analysis for primary versus secondary placements and type of procedure was performed. In addition, patients were asked for their subjective assessment. RESULTS Overall, Blom-Singer and Provox prostheses give very similar voice quality, lifetime, and patient satisfaction. Cleaning management is somewhat better for Provox, but there is a trend toward better overall voice quality for the Blom-Singer prosthesis. In subgroup analysis secondarily placed prostheses score somewhat better than primary placements, and patients with total laryngectomy have better voices than patients with extended laryngectomy combined with partial pharyngectomy. CONCLUSIONS Given the equal and good results in terms of voice quality, other factors (e.g., costs, surgery-related factors, maintenance, patient preference) should be taken into account when deciding which type of tracheoesophageal voice prosthesis to use.

Abstract
The conservation of a functional larynx is an important goal in the various attempts to improve the treatment of locally-advanced pharyngo-laryngeal cancers. Several axes have been followed: conservative surgery (subtotal laryngectomy), exclusive irradiation (with conventional or non-conventional fractionation), initial chemotherapy (followed by surgery or irradiation) or concomitant chemotherapy-radiotherapy. The numerous studies, including some major randomised trials, dealing with the issue of larynx preservation are reviewed in the present article. A critical comparison of their results and its integration in a consistent approach are difficult, especially because the different options are aimed at different patients. Total laryngectomy and its psychological and social consequences can be avoided in a significant number of patients, although the long term functional outcome is poorly known and the choice of the optimal treatment modality is largely dependent on the expertise and experience of the medical team.

Abstract
PURPOSE Induction chemotherapy has been proposed in the case of advanced laryngeal cancer in order to preserve laryngeal function in those patients who are complete responders. To clarify the treatment policies, a retrospective multicentric analysis of 116 patients with advanced carcinoma of the larynx treated by radical surgery and postoperative radiotherapy was carried out in order to evaluate prognostic factors for local control and survival. METHODS AND MATERIALS Between 1980 and 1985, 116 patients with Stage III squamous cell carcinoma of the larynx underwent radical surgery and postoperative radiotherapy with a curative intent. Treatments were very homogenous, and doses delivered were in the range of 50-65 Gy according to nodal involvement and surgical margins status. RESULTS The local recurrence rate and the local disease-free survival rate at 5 years were 22.5% and 76.3%, respectively. Actuarial survival at 5 years was 68.3% with 44 patients still alive with no evidence of disease (NED) with more than 5 years follow-up. For both overall survival and relapse-free survival, cervical node involvement with capsular rupture was found to be the only significant adverse pronostic factor in univariate and multivariate analysis. No other parameter was predictive either for local recurrence or for survival. CONCLUSIONS Local prognosis and survival depend largely on nodal involvement and capsular rupture while increasing doses of radiation strategy is likely to reduce the risk of local and nodal recurrence. Preservation of functional larynx is certainly an important goal to achieve when treating advanced carcinoma of the larynx, provided that local failure rate and survival be similar. In the unique randomized study previously published in the literature comparing radical surgery and postoperative radiotherapy to induction chemotherapy and radiotherapy, the local-regional failure rate was drastically increased in the chemotherapy arm. Other results from well-designed controlled studies are awaited before recommending systematic induction chemotherapy and larynx preservation in complete responders. On the other hand, testing synchronous or alternated chemotherapy vs. induction chemotherapy may address the pending questions about the optimal treatment of advanced laryngeal carcinoma.

Abstract
Transglottic cancer of the larynx crosses the laryngeal ventricle and involves both the vestibular and vocal folds. It has been described to spread within the paraglottic space (PGS). This region of adipose tissue, containing blood vessels and nerves, immediately adjacent to the thyroid laminae, was originally defined by Tucker and Smith (1962). However, the precise topographic relationships of this clinically important space are still controversely discussed. Therefore, a reinvestigation was done in serial sections of 19 plastinated adult human larynges. Laterally, the PGS is bordered by the thyroid cartilage. Superomedially, the PGS is continuous with the preepiglottic space (PES) in most specimens. In some cases, the PGS and the PES are completely separated from each other by a conspicuous collagenous fiber septum. Small projections of the paraglottic adipose tissue extend between the fibers of the thyroarytenoid muscle. Inferomedially, the PGS is bordered by the conus elasticus. Anteroinferior extensions of the PGS escape the larynx beneath the inferior rim of the thyroid cartilage. Posteroinferiorly, the paraglottic adipose tissue extends between the intrinsic laryngeal muscles and towards the cricoarytenoid joint. Dorsally, the PGS is bordered by the mucosal lining of the piriform sinus. A precise knowledge of the topography of the PGS can explain typical symptoms and routes of spread of tumorous growth: extension toward the hypopharynx, extension into the anterior extralaryngeal tissues, invasion of the thyroid cartilage, impairment of vocal cord movements due to infiltration of laryngeal muscles or immobilization of the cricoarytenoid joint.

Abstract
From 1983 to 1991, 31 patients underwent salvage laryngectomy for persistent or recurrent squamous carcinoma of the larynx (14), hypopharynx (15), or oropharynx (2) as part of a larynx preservation protocol. Laryngectomy was performed as a consequence of poor response to induction chemotherapy in 13 and for recurrent disease after completion of chemotherapy and irradiation in 18. Postoperative pharyngocutaneous fistula occurred in 39%, resulting in prolonged hospitalization. Local control was achieved in 68%, more often in patients with laryngeal as opposed to nonlaryngeal primaries (86% versus 53%; p = .05). The overall actuarial survival and disease-specific survival at 2 years were 32% and 38%, respectively. Disease-specific survival at 2 years was better in patients with laryngeal as compared to nonlaryngeal primaries (56% versus 24%; p = .02). There were no long-term survivors among the nonlaryngeal primary patients. In selected patients in whom larynx preservation failed, salvage laryngectomy was associated with acceptable local control and survival. Palliation was obtained in patients who were not cured by their laryngectomy. Future investigation will focus on identification of factors predicting complications and strategies to reduce the incidence and severity.

Abstract
The head and neck surgery workforce in the United States over the next 20 years is of significant interest to physicians, patients, and others. Using election to fellowship in the American Society for Head and Neck Surgery or the Society of Head and Neck Surgeons, or both, as the criteria for designation as a head and neck surgeon, a mathematical model was designed to project the growth of the head and neck surgery workforce through the year 2014. The current combined active membership of the two societies was analyzed to determine the impact of age distribution on this model. The paradigm assumes 30 new head and neck surgeons each year and includes the appropriate mortality rate for each cohort. Based on this model, the total number of head and neck surgeons should decrease slightly from 1109 in the year 1994 to 1028 in the year 2014. A steady-state supply of head and neck surgeons is therefore predicted.
