Abstract
BACKGROUND For oncologists and for patients, no site-specific clinical trial evidence has emerged for the use of concurrent chemotherapy with radiotherapy (ccrt) over radiotherapy (rt) alone for cancer of the hypopharynx (hpc) or for other human papilloma virus-negative head-and-neck cancers. METHODS This retrospective population-based cohort study using administrative data compared treatments over time (1990-2000 vs. 2000-2010), treatment outcomes, and outcomes over time in 1333 cases of hpc diagnosed in Ontario between January 1990 and December 2010. RESULTS The incidence of hpc is declining; the use of ccrt that began in 2001 is increasing; and the 3-year overall survival for all patients remains poor at 34.6%. No difference in overall survival was observed in a comparison of patients treated in the decade before ccrt and of patients treated in the decade during the uptake of ccrt. CONCLUSIONS The addition of ccrt to the armamentarium of treatment options for oncologists treating head-and-neck patients did not improve outcomes for hpc at the population level.

Caveolin-1 is overexpressed in hypopharyngeal squamous cell carcinoma and correlates with clinical parameters. Oncol Lett 2016; 12:2371-2374. [PMID: 27703521 PMCID: PMC5038869 DOI: 10.3892/ol.2016.4963] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2015] [Accepted: 06/10/2016] [Indexed: 11/05/2022] Open
Abstract
The present study aimed to identify the role of caveolin-1 (CAV1) in hypopharyngeal squamous cell carcinoma (HSCC) and identify its possible correlation with tumor clinical parameters. Expression of CAV1 was measured using immunohistochemical staining of 66 HSCC samples and 44 samples from morphologically normal tissues adjacent to the carcinomas. Expression of CAV1 in HSCC and paracancerous tissues were 71.2 and 9.5% respectively. Levels of CAV1 expression were significantly associated with tumor differentiation, tumor-node-metastasis stage and lymph nodes metastasis (P<0.05). The present study identified that expression of CAV1 in HSCC is significantly higher than in paracancerous tissues, suggesting that this high expression of CAV1 is associated with tumor invasion and metastasis.

Abstract
Supracricoid hemilaryngopharyngectomy (SCHLP) was performed in 147 patients over a 19-year period for previously untreated invasive squamous cell carcinoma of the pyriform sinus. With a minimum of 3 years' follow-up, the current retrospective series was designed to document the incidence, risk factors, and consequences of local recurrence following SCHLP. Before operation, 97.4% of patients had an induction chemotherapy regimen. A complete clinical response and a complete histologic regression were noted in 21.7% and 16.8% of patients, respectively. A significant statistical relationship (p = .0001) was noted between complete clinical response and complete histologic regression. Postoperative radiotherapy was used in 49.8% of patients. The overall local recurrence rate was 8.2%. The 5-year actuarial (Kaplan-Meier life-table method) local control estimate was 90.4%. As a function of T stage, the 5-year actuarial local control estimates were 96.2%, 91.1%, 92.9%, and 62.6% in patients with tumors classified as T1, T2, T3, and T4a, respectively. On univariate analysis, the overall local recurrence rate varied significantly, from 5.3% to 55.6% if the apex of the pyriform sinus was invaded (p = .02), 6.9% to 18.7% if the posterior pharyngeal wall was invaded (p = .03), and 6.3% to 60% if the margins of resection were positive (p = .02). In a stepwise regression model, positive margins of resection (odds ratio, 8.4; 95% confidence interval, 2.2 to 32.2; p = .002) and invasion of the apex of the pyriform sinus (odds ratio, 6.1; 95% confidence interval, 1.1 to 33.3; p = .04) were the variables statistically associated with an increased risk of local recurrence. Local recurrence resulted in a statistically significant increased risk of nodal recurrence (p = .005) and death (p < .004). The overall laryngeal preservation rate was 91.2%. From an oncological perspective, these results suggest that SCHLP should become a major tool in the armamentarium of the head and neck surgeon and should be integrated into future trials aimed at organ preservation in patients with invasive squamous cell carcinoma of the pyriform sinus.

Abstract
Objectives: Hypopharyngeal cancer (HPC) and cervical esophageal cancer (Ce) are aggressive tumors with a poor prognosis. Multiple lymph node metastases often occur in the upper mediastinum, as well as in the neck, and thus upper mediastinal dissection (MD) is crucial to improving the cure rate. However, excessive MD can increase postoperative morbidity and mortality, making it important to employ the proper technique and appropriate extent of dissection. In the present retrospective study we aimed to determine the proper extent of upper MD according to tumor site and stage. The benefit and risk of upper MD are also discussed. Methods: Chart review was completed for patients who underwent upper MD, including 64 patients with HPC, 21 patients with Ce, and 9 patients with Ce extending to involve the upper thoracic esophagus (Ce/Ut). The incidence and distribution of lymph node metastases in the upper mediastinum were assessed by postoperative histopathologic examination. Postoperative complications of upper MD, as well as the impact on survival and locoregional control, were also reviewed. Results: Upper mediastinal metastases were detected in 7.8% of HPC patients, 33.3% of Ce patients, and 55.6% of Ce/Ut patients. In HPC patients, mediastinal metastases were usually associated with T4 primary tumors (80%), whereas positive nodes in the upper mediastinum were detected regardless of T stage in both Ce and Ce/Ut. Only 1 Ce/Ut patient with a T4 tumor developed late nodal metastasis in the lower mediastinum. The 5-year disease-specific survival and locoregional control rates were 58.6% and 90.2% in HPC, 45.5% and 94.1% in Ce, and 38.9% and 77.7% in Ce/Ut, respectively. Rupture of the greater vessels after MD was observed in 5 cases (5.3%). Conclusions: The present results indicate excellent locoregional control rates following upper MD, while major complications such as arterial breakdown were rare. It is suggested that upper MD may be an essential and adequate procedure for patients with Ce or Ce/Ut tumors, and may also be required for cases of HPC with a T4 primary to improve locoregional control of the disease.

Abstract
Objective To compare survival data between patients who had surgery followed by concomitant chemoradiation therapy (CCRT) versus CCRT followed by early surgical salvage. Study Design Retrospective study. Methods We retrospectively analyzed 202 patients with hypopharyngeal carcinoma (HPC) who were treated with different treatment strategy according to the choice of the patients by surgery first or CCRT first. In 72 (35.6%) cases, the primary treatment was surgery. Postoperative radiation therapy was given to 47 patients. Radiation therapy was the primary treatment in 130 (64.4%) patients; among them, 69 (34.2%) patients received salvage surgery within 2 months after CCRT course if there was a residual tumor visible on post-CCRT CT image or clinically residual tumor. Results and Conclusion The 5-year disease-specific survival rate was 80% for stage I-II, 44.8% for stage III, and 14.3% for stage IV disease. Surgery plus concomitant chemoradiotherapy led to a better survival rate than CCRT plus salvage surgery in patients with stage III-IV HPC.

Abstract
Disease specific patterns of volatile organic compounds can be detected in exhaled breath using an electronic nose (e-nose). The aim of this study is to explore whether an e-nose can differentiate between head and neck, and lung carcinoma. Eighty-seven patients received an e-nose measurement before any oncologic treatment. We used PARAFAC/TUCKER3 tensor decomposition for data reduction and an artificial neural network for analysis to obtain binary results; either diagnosed as head and neck or lung carcinoma. Via a leave-one-out method, cross-validation of the data was performed. In differentiating head and neck from lung carcinoma patients, a diagnostic accuracy of 93 % was found. After cross-validation of the data, this resulted in a diagnostic accuracy of 85 %. There seems to be a potential for e-nose as a diagnostic tool in HNC and lung carcinoma. With a fair diagnostic accuracy, an e-nose can differentiate between the two tumor entities.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs of approximately 22 nucleotides that negatively regulate gene expression at the post-transcriptional level. Downexpression of miR-140-5p was reported in some human cancers, and combined with a reduction of cell migration and invasion, suggesting that miR-140-5p functions as a tumor suppressor. However, little is known about the expression and function of miR-140-5p in hypopharyngeal squamous cell carcinoma (HSCC). In this research, we found that miR-140-5p was significantly downregulated in HSCC tissues and correlated to tumor classification and lymph node metastasis. Restoration of miR-140-5p suppressed the migration and invasion of FaDu cells, and decreased the protein expression levels of ADAM10. Furthermore, the luciferase reporter assay revealed that miR-140-5p was directly bound to ADAM10 mRNA and knockdown of ADAM10 could inhibit FaDu cell migration and invasion and reduced the protein expression levels of and Notch1 intracellular domain (NICD1). Of note, knockdown of Notch1 could inhibit the migration and invasion of FaDu cells and rescued the effect of miR-140-5p inhibitor in FaDu cells. Taken together, our study demonstrates that miR-140-5p suppresses tumor migration and invasion by inhibiting ADAM10-mediated Notch1 signaling pathway and suggests that miR-140-5p could have potential therapeutic applications in HSCC.

Abstract
OBJECTIVES Hypopharyngeal squamous cell carcinoma (HPSCC) is an aggressive disease in the head and neck region. Therefore, simple and useful prognostic predictors of HPSCC are needed for clinical practice. This study investigates the prognostic significance of preoperative neutrophil-to-lymphocyte ratio (NLR) in patients with HPSCC who received radical resections. METHODS Retrospective review was conducted on medical records at a tertiary referral hospital involving 146 consecutive patients who underwent radical resection for HPSCC between January 2000 and December 2010. The prognostic significance of NLR and other clinicopathologic factors was analyzed. The relationships between the NLR value and clinicopathologic factors were also evaluated. RESULTS The study cohort consisted of 146 patients with HPSCC, with a mean age of 57.5 years (range, 34-89 years). The median number of NLR was 2.28 (range, 0.71-8.75). On the basis of this median value, the cutoff value of NLR was set as 2.3. The patients were divided into 2 groups: a low (<2.3) NLR group and a high (≥2.3) NLR group. Patients with NLR of 2.3 or more had significantly higher incidence of wound complications (P = 0.026). The 3-year overall survival rate was 69.9% in patients in the low NLR group and 27.4% in those in the high NLR group (P <0.001; hazard ratio;2.99; 95% confidence interval, 1.91-4.67). CONCLUSIONS Results showed that high preoperative NLR is associated with increased wound complications and poor survival in patients with HPSCC.

Abstract
OBJECTIVE Patients with advanced hypopharyngeal or cervical esophageal cancer have a comparatively high risk of also developing thoracic esophageal cancer. Pharyngolaryngectomy with total esophagectomy is highly invasive, and few reports about it exist. We examined the postoperative complications and respective countermeasures and prognoses of patients who underwent pharyngolaryngectomy with total esophagectomy. STUDY DESIGN Case series with chart review. SETTING Department of Head and Neck Oncology, Cancer Institute Hospital of Japanese Foundation for Cancer Research, Japan. SUBJECTS AND METHODS We examined the postoperative complications and respective countermeasures and prognoses of 40 patients who underwent pharyngolaryngectomy with total esophagectomy in our hospital. RESULTS Postoperative complications were observed in 23 patients (57.5%) and consisted of 8 groups: tracheal region necrosis in 5 patients; neck abscess formation/wound infection in 5; fistula in 4; tracheostomy suture leakage in 2; ileus in 2; lymphorrhea in 2; pulmonary complications in 2; and other complications, including hemothorax, tracheoinnominate artery fistula, temporary cardiac arrest due to intraoperative mediastinum operation, methicillin-resistant Staphylococcus aureus enteritis, and sepsis, in 1 patient each. A lethal complication-brachiocephalic vein hemorrhage due to tracheostomy suture leakage and hemorrhagic shock due to tracheoinnominate artery fistula-occurred in 2 (5%) patients. The crude 5-year survival rate was 48.6%. CONCLUSIONS Serious postoperative complications were related to tracheostomaplasty. Although pharyngolaryngectomy with total esophagectomy is highly invasive, we believe that our outlined treatment method is the most appropriate for cases of advanced hypopharyngeal or cervical esophageal cancer that also requires concurrent surgery for esophageal cancer.

Abstract
MicroRNAs (MiRNAs) have been recognized to regulate cancer initiation and progression in carcinogenesis as either oncogenes or tumor suppressor genes, but their role in hypopharyngeal cancer development is not clearly defined. To determine whether miRNA-203 can promote tumor growth in human hypopharyngeal squamous cell carcinoma, we conducted experiments on the functional study of miRNA-203 and identification of miRNA-203 regulated target genes in hypopharyngeal cancer cells. We found that cell proliferation and cell colony-forming increased more in the miRNA-203 up-regulated cancer cells than in the negative control cancer cells. Up-regulation of miRNA-203 accelerated cell cycle progression in hypopharyngeal cancer cells. TP63 and B3GNT5 mRNAs were identified and validated as targets of miRNA-203. However, transwell assay and wound scratch assay showed that miRNA-203 did not involve in invasion and metastasis in hypopharyngeal cancer cells. According to the results, we conclude that miRNA-203 can promote tumor growth in human hypopharyngeal squamous cell carcinoma. These results provide the convincing evidence for the first time that up-regulation of miRNA-203 contributes to the malignancy of hypopharyngeal squamous cell carcinoma, possibly through down-regulating TP63 and B3GNT5.

Abstract
OBJECTIVES This study aimed to determine the efficacy and feasibility of preoperative radiotherapy with or without chemotherapy (XRT) followed by surgery of locally advanced pyriform sinus carcinoma. MATERIALS AND METHODS We performed a retrospective study of 482 patients with T3 and T4 pyriform sinus carcinoma treated with curative intent between 1979 and 2008. The patients were divided into 4 groups according to different treatment patterns. RESULTS The 5-year disease-special survival rate was 32%. Survival was best for the patients treated with surgery followed by XRT (41.1%) and with neoadjuvant XRT followed by surgery (39.4%), but it was worse with surgery only (27.1%) and XRT alone (23%). The disease-special survival was significantly different between the patients who accepted multidisciplinary therapy and those who accepted single therapy (P<0.001). The 5-year laryngeal function preservation survival rate of the patients with XRT followed by surgery was 13.6%, which was similar to those with XRT alone (16.2%), and superior to those who accepted surgery followed by XRT (3.8%) and surgery alone (0). Multivariate analysis results revealed that treatment pattern is an independent predictor of both overall and laryngeal function preservation survival rates (P < 0.001; hazard ratio, 0.56; 95% confidence interval, 0.44-0.71). Perioperative wound complications were not different among the patients in the 3 groups who accepted surgical treatment (P > 0.05). CONCLUSIONS The results suggested that neoadjuvant XRT followed by planned surgery was feasible with satisfactory oncological and functional outcomes.

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
BACKGROUND The number and ratio of positive lymph nodes are important prognostic factors in gastric cancer, but there is little data reported in hypopharyngeal cancer. METHODS Medical data from 81 patients with hypopharyngeal cancer undergoing radical hypopharyngectomy and cervical lymph node dissection were reviewed. RESULTS The median survival time was 84, 54, 30, and 13 months in patients with N0, N1, N2, and N3, respectively, and 84, 51, and 17 months with positive lymph node ratios (N ratio) 0, <10%, and >10%, respectively. Of the 24 N1 patients, the 20 patients that had an N ratio <10% had a better prognosis than the 4 patients with an N ratio >10%. Similar data was seen for the N2 patients. Tumor (T) classification, adjuvant therapy, and N ratio were independent prognostic factors in multivariate analysis. CONCLUSION The positive lymph node ratio is complementary to the current N classification system.

Abstract
For patients without symptoms and at risk, there is no established early detection program to discover carcinomas of the upper aerodigestive tract in the sense of secondary prevention. Such type of prevention seems even more desirable because the chances for a cure and the quality of life are strongly dependent on the stage of the tumor and the time of the initial diagnosis. Six hundred and eight patients without symptoms but at least one of the self-reported risk factors "smoking", "alcohol consumption" or "reflux" were examined with an endoscope or an optical microscope for pathological findings in the upper aerodigestive tract once a year. In addition, the incidence of malignancies of the upper aerodigestive tract between 2001 and 2010 was determined through the Cancer Registry of Schleswig-Holstein. Tissue samples were taken from 18 of the 608 patients. Eleven patients (1.8%) had a squamous cell carcinoma. Another patient suffered from non-Hodgkin's lymphoma and one from larynx tuberculosis. The ratio of detected malignancies in the oral cavity and the oropharynx on the one hand and the hypopharynx and larynx, which can only be examined by endoscopes, on the other hand were in our cohorts and in our survey according to the cancer registry was 5/6. The above-described methods allow examining risk patients easily and safely. According to current publications, the ratio of the found malignancies exceeds the expected ratio significantly, which presumably was caused by the examination targeting patients at risk. Due to the expanded examination area using optical instruments more than doubles the rate of discoverable malignancies compared to the limitations posed by the examination of directly visible areas of the oral cavity of the oropharynx.

Abstract
CONCLUSIONS Endoscopic laser microsurgery (ELM) provides comparable oncological outcomes, and improved functional recovery and laryngeal preservation compared with open partial laryngopharyngectomy (OPLP) in patients with early squamous cell carcinoma of the hypopharynx (HPSCC). The use of open surgery is declining. The outcome of the study provides evidence-based recommendations for surgical choices in HPSCC treatment. However, it is not conclusive without a larger prospective study. OBJECTIVES To compare the functional and oncological results of ELM and OPLP in HPSCC and examine surgical trends. METHODS From 1990 to 2008, 53 HPSCC patients undergoing ELM (n = 25) and OPLP (n = 28) were included. Functional recovery, oncological results, and laryngeal preservation rate were analyzed. RESULTS Patients who underwent ELM demonstrated a shorter decannulation period (7 vs 11 days, p = 0.010), time using a nasogastric tube (7 vs 16 days, p = 0.043), and hospitalization stay (12 vs 22 days, p = 0.0061) than those who underwent OPLP. The 3-year overall and disease-specific survival rates were comparable between ELM and OPLP (79% vs 64%, p = 0.151, and 83% vs 71%, p = 0.320, respectively). The ELM patients had better laryngeal preservation (92% vs 71%, p = 0.048). The number of OPLPs performed has decreased since 2000 (68% before vs 32% after, p < 0.0001).

Abstract
OBJECTIVE Review of the literature on the role of surgery in the management of head and neck cancer in the era of organ preservation. METHOD Literature search based on the essential practice guidelines set out by the US National Comprehensive Cancer Network. RESULTS Despite the increasing popularity of non-surgical treatment options, the surgeon remains a key figure in the multidisciplinary head and neck cancer team, along with the radiation oncologist, the medical oncologist and the speech and swallowing therapist. Even when organ preservation is successful, early and late toxicity may cause serious complications, including laryngeal dysfunction with a 'frozen larynx'. When organ preservation fails, salvage surgery is often associated with increased complications and reduced survival. CONCLUSION There is a definite need to apply more rigorous standards to the use of organ preservation strategies, and to re-evaluate the role of surgery in head and neck cancer treatment.

Abstract
CONCLUSION Partial laryngopharyngectomy (PLP) provides acceptable oncologic results and laryngeal preservation rate in selected patients with squamous cell carcinoma of the hypopharynx. Even when local recurrence develops, the chance of successful salvage is still high. OBJECTIVES To evaluate the oncologic results and laryngeal preservation rate in patients with squamous cell carcinoma of the hypopharynx who underwent PLP. METHODS The results of 39 patients who underwent PLP were compared with those of 91 patients who underwent total laryngectomy (TL). RESULTS The distribution of the primary T stages were 23 (59%) pT2, 9 (23%) pT3, and 7 (18%) pT4; the pathologic stages were 8 patients (21%) stage II, 9 (23%) stage III, and 22 (56%) stage IV. All of the patients also had ipsilateral or bilateral neck dissections. Eighteen patients (46%) received postoperative adjuvant therapy. After a median follow-up of 39 months, 17 patients (44%) had recurrence, including 12 local, 2 regional, and 3 distant lesions. The 5-year overall and disease-specific survival were 44% and 56%, respectively; functional preservation was 62%. The recurrence rate was similar in patients treated with PLP and TL (44% vs 36%, p = 0.431); the local recurrence rate was higher after PLP than after TL (31% vs 8%, p = 0.001). The salvage surgery was successful in four of the six patients (67%). After salvage treatment, the 5-year overall survival (44% vs 47%) and disease-specific survival (56% vs 62%) were similar in the two groups.

Abstract
PURPOSE Centromere protein H (CENP-H) and Ki67 are overexpressed in some malignancies, but whether they are predictors of survival after primary resection for hypopharyngeal squamous cell carcinoma (HSCC) remains unknown. METHODS We assessed immunohistochemical expression of CENP-H and Ki67 in 112 HSCC specimens collected between March 2003 and March 2005 for analysis by clinical characteristics. The Kaplan-Meier method was used to analyze relapse-free survival and logistic multivariate regression to determine risk factors of relapse-free survival. Cholecystokinin octapeptide assays and flow cytometry were used to examine cell proliferation and apoptosis after siRNA inhibition of CENP-H in HSCC cells. RESULTS Overall, 50 (44.6%) HSCC specimens showed upregulated CENP-H expression and 69 (61.6%) upregulated Ki67. An increased CENP-H protein level was associated with advanced cancer stage and alcohol history (P=0.012 and P=0.048, respectively) but an increased Ki67 protein level only with advanced cancer stage (P=0.021). Increased CENP-H or Ki67 were associated with short relapse-free survival (P<0.001 or P=0.009, respectively) and were independent predictors of relapse-free survival (P=0.001 and P=0.018, respectively). siRNA knockdown of CENP-H mRNA inhibited cell proliferation and promoted cancer cell apoptosis in vitro. CONCLUSIONS Upregulated CENP-H and Ki67 levels are significantly associated with short relapse-free survival in HSCC. These factors may be predictors of a relapsing phenotype in HSSC cases.

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
OBJECTIVES Squamous cell carcinoma (SCC) of the hypopharynx represents a distinct clinical entity among other cancers of the head and neck region. Despite recent advances in chemoradiotherapy, surgery remains the preferred therapeutic option for locally advanced disease and salvage for failure after chemo-radiotherapy. In this article, several aspects of surgical and non-surgical approaches in the management of hypopharyngeal cancer are discussed. METHODS A search in pubmed was made for publications with regard to the management of hypopharyngeal carcinoma. RESULTS In early-staged hypopharyngeal cancer, the overall and disease-specific survival rates after organ-preserving radiotherapy is comparable to that after surgery. However, for advanced staged disease, the results initial surgery with post-operative adjuvant radiotherapy was superior to chemoradiotherapy alone. The incidence of occult nodal metastasis is found to be more than 20%. Selective neck dissection removing cervical lymph node level II-IV is the procedure of choice for patients with clinically N0 neck. Contralateral nodal clearance may also be considered in tumors involving the medial wall of the pyriform recess, post-crioid region or the posterior wall, and those with ipsilateral palpable nodal metastasis and clinical stage IV disease. Transoral robotic surgery (TORS) has the potential value as the minimally invasive procedure for the management of carcinoma of the hypopharynx. CONCLUSIONS The treatment strategy for carcinoma of the hypopharynx has been evolving with time. Organ preserving chemoradiotherapy has been the treatment of choice for early stage disease, with surgical resection and reconstruction reserved for advanced and recurrent tumors.

Abstract
The principles of open versus laser microsurgical approaches for partial resections of the larynx are described, oncologic as well as functional results discussed and corresponding outcomes following primary radiotherapy are opposed. Over the last decade, the endoscopic partial resection of the larynx has developed to an accepted approach in the treatment of early glottic and supraglottic carcinomas thus leading to a remarkable decline in the use of open surgery. Comparing the various surgical approaches of laryngeal partial resections, the oncological outcome of the patients, as far as survival and organ preservation are concerned, are comparable, whereas functional results of the endoscopic procedures are superior with less morbidity. The surgical procedures put together, are all superior to radiotherapy concerning organ preservation. Transoral laser microsurgery has been used successfully for vocal cord carcinomas with impaired mobility or fixation of the vocal cord, supraglottic carcinomas with infiltration of the pre- and/or paraglottic space as well as for selected hypopharyngeal carcinomas. It has been well documented that laser microsurgery achieves good oncological as well as functional results with reasonable morbidity. However, patients with those tumours have been successfully treated by open partial resections of the larynx at medical centres with appropriate expertise. The initially enthusiastic assessment of study results concerning the efficacy of various protocols of chemoradiation with the intent of organ preservation for laryngeal and hypopharyngeal carcinomas are judged more cautious, today, due to recent reports of rather high rates of late toxicity complications.

Abstract
OBJECTIVE To date, no secondary prevention program is in place for patients carrying an increased risk for developing head and neck cancer (HNSCC). In terms of successful, long-term curative therapy and increased quality of life, it would be useful to detect such diseases at an early stage. PATIENTS AND METHODS A total of 370 patients with at least one risk factor such as "smoking", "alcohol", or "reflux disease" and without any symptoms were examined during a 1-year period using standard HNO methods (e. g. endoscopy) for suspicious alterations of the mucosa of the upper aerodigestive tract. RESULTS In 13 (3.5%) of all 370 cases a biopsy was taken for further diagnosis. Squamous cell carcinoma was found in eight cases, while one further patient was suffering from non-Hodgkin lymphoma. CONCLUSIONS It is simple and safe to examine patients at risk of developing HNSCC by standard HNO methods. The rate of detected carcinomas is much higher than in former investigations, likely because our survey focused only on patients with specific risk factors.

Abstract
BACKGROUND Limited data evaluate intensity-modulated radiotherapy (IMRT) for cancers of the hypopharynx and larynx. We report clinical outcomes and failure patterns for these patients. METHODS Between September 2001 and December 2007, 42 patients with squamous cell carcinoma (SCC) of the hypopharynx (n = 23) and larynx (n = 19) underwent IMRT, 11 postoperatively and 31 definitively. Thirty-six received systemic therapy. Median follow-up was 30 months among surviving patients. RESULTS Three local failures occurred within the high-dose region and 3 occurred in regional nodes. Seven patients developed distant metastasis as the initial failure. Three-year actuarial estimates of locoregional control, freedom from distant metastasis, and overall survival rates were, respectively, 80%, 72%, and 46%. CONCLUSIONS IMRT provides good locoregional control for SCC of the hypopharynx and larynx compared with historical controls. Locoregional relapses occurred in the high-dose volumes, suggesting adequate target volume delineation. Hypopharyngeal tumors, which fare worse than laryngeal tumors, warrant investigation of more aggressive treatment.

Abstract
Objectives To evaluate the oncologic and functional results of larynx-preserving partial pharyngectomy (LPP) via lateral pharyngotomy approach as a primary treatment for small (T1 or T2) hypopharyngeal squamous cell carcinoma (HPSCC). Methods We performed a retrospective review of 23 patients who underwent LPP through lateral pharyngotomy approach for small HPSCC at the our department between January 1991 and June 2007. Fourteen (61%) patients had adjuvant postoperative radiotherapy. Results The 2-years and 5-years disease specific survival rate was 77% and 61%, respectively. Nine patients (39%) had tumor recurrence. The most common pattern of recurrence was isolated distant failure (n=4, 44%) followed by local (n=2, 22%) and loco-regional (n=3, 34%) recurrence. The ultimate cure rate of the primary tumor was 87% (20 of 23). Twenty-two of the 23 patients (95%) could be decannulated, tolerate an oral diet, and had acceptable postoperative phonatory function. Conclusion LPP via lateral pharyngotomy approach appears to be a feasible procedure for selected small HPSCC patients in terms of both oncologic and functional outcomes.

Abstract
CONCLUSION Organ preservation surgery with partial pharyngectomy preserving the larynx is feasible for the treatment of advanced hypopharyngeal cancer with comparable local control and preservation of function. OBJECTIVES To examine the feasibility and therapeutic effects of organ preservation surgery for advanced hypopharyngeal cancer. METHODS Fourteen patients with stage III/IV hypopharyngeal cancer were treated by partial pharyngectomy with or without partial laryngectomy to preserve the larynx. Ten cases were T1/2 primary while four cases had T3/4 tumors. Reconstruction of the pharyngolarynx was completed by primary mucosal suture in six, while free forearm flap was used in eight cases. Induction chemotherapy was administered for six cases including three with T3/4 tumors. RESULTS Five-year overall survival and disease-specific survival rates were 57.1% and 66.7%, respectively. The 5-year locoregional control rate was 66.7% and the larynx preservation rate was 100%. No patients presented with local recurrence at the pharyngolaryngeal segment, while two cases showed nodal recurrence, from which they died. Tracheal stoma was closed in 9 of 14 cases. Vocal function was excellent in five cases, moderate in five, and poor in three. Swallowing function was excellent to moderate in eight cases and poor in six.

Abstract
CONCLUSIONS It is suggested that radiotherapy might be the first choice for stage I/II hypopharyngeal cancer, and that adjuvant treatment might be necessary for stage II patients to prevent distant metastasis. OBJECTIVES To update the therapeutic outcome of early hypopharyngeal cancer. METHODS Twenty-eight patients with stage I/II hypopharyngeal cancer (8 in stage I, 20 in stage II) were treated at Kyoto University Hospital between 1995 and 2007. Of 8 cases in stage I, radiotherapy was applied for 4 cases, and surgical treatment for another 4, while 13 of 20 cases in stage II underwent radiotherapy and the remaining 7 cases underwent surgery. RESULTS The 5-year cumulative disease-specific survival and larynx preservation rates were 74.6% and 73.2%, respectively. Recurrent tumors were found in two cases in stage I treated by surgery and in five cases in stage II treated with radiotherapy. Two of five recurrent cases in stage II were rescued by salvage surgery. Distant metastasis to the lung appeared in two cases in stage II after initial treatment.

Abstract
CONCLUSION Treatment of advanced hypopharyngeal cancer has become more conservative and more multidisciplinary, and the prognosis has been improved. Induction chemotherapy has the potential to extend organ preservation therapy even in cases with locally advanced primary lesion. It is also important to develop a strategy to reduce distant metastasis and to keep track of second primary cancers. OBJECTIVES To update the therapeutic outcome of advanced hypopharyngeal cancer. METHODS A total of 72 cases with stage III/IV hypopharyngeal cancer were treated at Kyoto University Hospital during 2000-2008. Surgery was performed in 56 cases; total pharyngolaryngoesophagectomy (TPLE) in 39 cases and partial pharyngectomy (PPX) preserving the larynx in 17 cases. Radiotherapy (RT) with or without concurrent chemotherapy was applied in 16 cases. Induction chemotherapy (ICT) has been applied for 14 cases since 2006 to achieve organ preservation and reduction of distant metastasis. The follow-up period varied from 12 months to 96 months (mean 32 months). Therapeutic outcomes were chart reviewed. RESULTS Five years cumulative overall and disease-specific survival (DSS) rates were 52.1% and 63.8%, respectively. DSS rates in cases treated with surgery and those with RT were 65.1% and 56.1%, respectively. N2c status showed the worst prognosis according to nodal disease classification. Local control rates for cases treated with TPLE, PPX, and RT were 97.3%, 100%, and 80.4%, respectively. The effective rate of ICT was 79%, and laryngeal preservation was achieved in 79% of the cases with ICT. Recurrence occurred in 20 cases. Approximately half of the recurrence was distant disease. In the end, 17 cases died of the primary disease, while 10 cases died of other causes, mainly second primary cancers.

Abstract
Survival and quality of life in head and neck cancer are directly linked to the size of the primary tumor at first detection. In order to achieve substantial gain at these issues, both, primary prevention and secondary prevention, which is early detection of malignant lesions at a small size, have to be improved. So far, there is not only a lack in the necessary infrastructure not only in Germany, but rather worldwide, but additionally the techniques developed so far for early detection have a significance and specificity too low as to warrant safe implementation for screening programs. However, the advancements recently achieved in endoscopy and in quantitative analysis of hypocellular specimens open new perspectives for secondary prevention. Chromoendoscopy and narrow band imaging (NBI) pinpoint suspicious lesions more easily, confocal endomicroscopy and optical coherence tomography obtain optical sections through those lesions, and hyperspectral imaging classifies lesions according to characteristic spectral signatures. These techniques therefore obtain optical biopsies. Once a "bloody" biopsy has been taken, the plethora of parameters that can be quantified objectively has been increased and could be the basis for an objective and quantitative classification of epithelial lesions (multiparametric cytometry, quantitative histology). Finally, cytomics and proteomics approaches, and lab-on-the-chip technology might help to identify patients at high-risk. Sensitivity and specificity of these approaches have to be validated, yet, and some techniques have to be adapted for the specific conditions for early detection of head and neck cancer. On this background it has to be stated that it is still a long way to go until a population based screening for head and neck cancer is available. The recent results of screening for cancer of the prostate and breast highlight the difficulties implemented in such a task.

Abstract
Background: Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive malignancy with one of the worst prognoses among all head and neck cancers. Greater understanding of the pertinent molecular oncogenic pathways could help improve diagnosis, therapy, and prevention of this disease. The aim of this study was to identify tumour-suppressive microRNAs (miRNAs), based on miRNA expression signatures from clinical HSCC specimens, and to predict their biological target genes. Methods: Expression levels of 365 human mature miRNAs from 10 HSCC clinical samples were screened using stem-loop real-time quantitative PCR. Downregulated miRNAs were used in cell proliferation assays to identify a tumour-suppressive miRNA. Genome-wide gene expression analyses were then performed to identify the target genes of the tumour-suppressive miRNA. Results: Expression analysis identified 11 upregulated and 31 downregulated miRNAs. Gain-of-function analysis of the downregulated miRNAs revealed that miR-489 inhibited cell growth in all head and neck cancer cell lines examined. The gene PTPN11 coding for a cytoplasmic protein tyrosine phosphatase containing two Src Homology 2 domains was identified as a miR-489-targeted gene. Knockdown of PTPN11 resulted in the inhibition of cell proliferation in head and neck SCC cells. Conclusion: Identification of the tumour-suppressive miRNA miR-489 and its target, PTPN11, might provide new insights into the underlying molecular mechanisms of HSCC.

Abstract
PURPOSE The aim of the present study was to compare the incidence, patterns, and survival of second primary malignancy (SPM) in patients with squamous cell carcinoma of the larynx (LSCC) and hypopharynx (HPSCC). METHODS We retrospectively review the medical record of 581 previously untreated patients with LSCC (392 cases) and HPSCC (189 cases) who received primary surgery with or without postoperative radiotherapy from 1990 to 2000. Data including age, sex, risk factors, subsites and TNM stage of primary tumor, treatment, site and incidence of SPM, and prognosis were collected from medical charts. RESULTS Groups with HPSCC had a higher incidence (4.2% vs 2.9% annual rate) and shorter median time (30 vs 59 months) developing SPM rather than LSCC. Fifty-five percent of the SPM occurred in the respiratory axis in LSCC, and 66% developed in the digestive axis in HPSCC. The factors influencing the appearance of SPM included early T stage, tobacco use, and less tumor recurrence. Long-term survival was poorer in those with than without SPM (38% vs 49% at 10 years). CONCLUSIONS There is a tendency for SPM to occur in the respiratory axis (lung and larynx) in LSCC and in the digestive axis (oral cavity, pharynx, and esophagus) in HPSCC. This information is important for posttreatment follow-up.

Abstract
BACKGROUND Comorbidity has an impact on survival in laryngeal cancer in several reports. However, the importance of comorbidity in hypopharyngeal cancer (HPC) has not been reported. METHODS A retrospective medical record review of 156 patients with HPC treated between 1995 and 2005 was performed. Comorbid illness was measured by the Adult Comorbidity Evaluation-27. A Cox proportional hazards model was used to determine the factors related to overall survival. RESULTS Comorbidity was absent in 55 (35.2%) of the patients, mild in 39 (25%), moderate in 28 (17.9%), and severe in 34 (21.8%). There were statistically significant differences between the survival rates in accord with age, stage, subsite, and comorbidity (45.1% for none or mild vs 27.7% for moderate or severe; p = .0073). Age, stage, and comorbidity were identified as independent prognostic factors in the multivariate analysis. CONCLUSION Comorbidity, along with the clinical stage, should be considered in treatment planning for patients with HPC.

Abstract
Dysphagia is an important alarm symptom, commonly associated with chest pain; it is often associated with reflux disease, xerostomia, or tumors of the head and neck. However, simple diagnoses such as aspiration of a foreign body can be overseen and may result in major complications, such as perforation and mediastinitis. It is thus of crucial importance that a thorough gastrointestinal, cardiac, and radiologic examination precede a rigid esophagoscopy by an otolaryngologist. In this article the differential diagnoses of dysphagia are discussed, and the otolaryngologist's approach to diagnosis and therapy are explained.

Abstract
OBJECTIVE We investigated the risk factors for metastasis to retropharyngeal lymph nodes (RPLNs) and the significance of dissection of RPLNs in hypopharyngeal cancer. Metastasis to the RPLNs is an important prognostic factor in head and neck cancer, especially in hypopharyngeal cancer. METHODS Study subjects were 129 cases who received primary treatment at nine leading medical facilities in the field of head and neck cancer management in Japan. Focusing on RPLNs, we compared prognosis in RPLN-metastasis-positive, RPLN-metastasis-negative, RPLN-dissected and RPLN-non-dissected cases. RESULTS The 5-year survival rate for the entire study group was 41.1%. Metastasis to RPLNs occurred during the follow-up period in 13.2%. RPLN dissection was performed in 32 of the 129 cases at the time of primary treatment. In the RPLN-dissected group, the 5-year survival rate in the RPLN-metastasis-positive subgroup was 30.0%, whereas that in the RPLN-metastasis-negative subgroup was 41.2%, showing no statistically significant difference. Among 17 cases having RPLN metastasis, 30.0% in the RPLN-dissected group (n = 10) survived for 5 years versus none in the RPLN-non-dissected group (n = 7). The rate of RPLN metastasis was higher in primary hypopharyngeal cancer of the posterior wall/post-cricoid area (PC/PW) compared with that of the piriform sinus (P = 0.020). CONCLUSIONS We recommend RPLN dissection at the time primary of treatment of hypopharyngeal cancer, especially in cases with cancer at subsites PC/PW, as RPLN dissection is expected to improve prognosis. The primary subsites PC/PW are associated with a risk of RPLN metastasis.

Background The aim of this study is to assess the functional and oncologic results of supracricoid hemilaryngopharyngectomy and report our experience in the technique, local control and overall survival rates. Materials and methods 18 selected patients with pyriform sinus cancer treated by supracricoid hemilaryngopharyngectomy in a University Hospital setting. Retrospective chart review was used to assess functional and oncologic results of the procedure. Results The actuarial 5 year survival rate in our study was 55.56% and the actuarial neck recurrence rate was 16.67%. All patients were successfully decannulated. Aspiration pneumonia was the most common postoperative complication (22.23%) and was treated mostly conservatively. One patient required a temporary gastrostomy but no patient needed total laryngectomy in the postoperative period. Conclusion Supracricoid hemilaryngopharyngectomy in experienced hands is a reliable technique for selected patients with pyriform sinus cancer.

Abstract
INTRODUCTION Hypopharyngeal cancers have extensive submucosal spread, high risk of nodal involvement and relatively high propensity of distant metastases. Contemporary paradigms for hypopharyngeal cancers aim to maximize loco-regional control while attempting to preserve laryngo-pharyngeal form and function. AIMS To retrospectively review outcome of large cohort of patients with hypopharyngeal cancers treated with curative intent radiotherapy with or without systemic chemotherapy in an academic tertiary referral centre. MATERIAL AND METHODS Medical records of patients with hypopharyngeal cancers treated with primary non-surgical approaches over a 15-year period were reviewed retrospectively. Loco-regional control (LRC) and disease-free survival (DFS) were considered as outcome measures. RESULTS Electronic search of database identified 501 patients with hypopharyngeal cancers treated with definitive radiotherapy. The median age was 55 years (range 20-87 years) and median radiotherapy dose 70 Gy (range 5.4-72 Gy). With a mean follow-up period of 22 months (median 12 months), the 3-year LRC and DFS was 47.1% and 40.9% respectively. Stage (T-stage, N-stage, overall stage grouping), and age influenced outcome significantly. The 3-year LRC for T1-T2 disease was 49.7% versus 43.1% for T3- T4 stage (p0.056). The 3-year DFS was 49.4% and 36.9% respectively (p0.014). The 3-year LRC and DFS for N0; N1; and N2-3 disease was 57.3% & 54.3%; 40.5% & 35.3%; and 33% & 27% respectively with highly significant p-values. CONCLUSION This is an outcome analysis of the largest cohort of patients with hypopharyngeal cancers managed with primary non-surgical approaches. Stage and age remain the most important determinants of outcome.

Abstract
Squamous cell carcinoma of the hypopharynx (HPSCC) tends to present with an advanced stage. Surgery with postoperative radiation or chemoradiation therapy has been the standard treatment for HPSCC. Radical surgery may result in a large surgical defect of the hypopharyngeal and cervical esophageal regions. Reconstruction of the surgical defect is also important after ablation procedures. Many reconstructive methods have been developed. However, each method has its own advantages and disadvantages. The ideal method for hypopharyngeal reconstruction should have the following attributes if possible: single-stage procedure, high success rate of tissue transfer, low donor-site morbidity, low fistula and stenosis rates, restoration of the ability to speak and swallow, able to achieve successful reconstruction in a heavily radiated area and tolerance of postoperative radiotherapy. In this review article, we discuss the indications and drawbacks of several reconstructive methods that have been frequently used in our clinical practice. Finally, we will introduce the technique of laryngotracheal flap reconstruction, which was developed in our institution and has proved to be a simple and reliable method for hypopharyngeal reconstruction.

Abstract
OBJECTIVES Knowledge of prognostic factors is essential for patient care and research. The objectives of this study were to demonstrate that prognostic factors and their impact can vary depending on study design and to examine the relationships between select prognostic factors. METHODS Retrospective population-based study of patients with cancer of the hypopharynx in Ontario, Canada, from January 1990 to December 1999 identifying and comparing prognostic factors for different survival outcomes and different subpopulations using Kaplan Meier analysis and Cox Proportional Hazards models. RESULTS The impact of prognostic factors varies within subgroups of a study population, varies with treatment decisions, and varies with the outcome of interest. CONCLUSIONS N and T category were the dominant prognostic factors in hypopharyngeal cancer. Performance status was an independent predictor of survival.

Abstract
CONCLUSION Relapse-free survival (RFS) of patients suffering from cancers located in the oro- and hypopharynx (COH) is strongly related to the localization and initial tumor stage; 25% of relapses remain undetected by the patients themselves. To detect relapse at an early stage oncologic follow-up should be performed at close intervals during the first 3 years. For confirmation imaging procedures should be indicated generously as well as control endoscopy under general anesthesia. OBJECTIVES COH are often characterized by a rapid progression of disease in case of relapse. Most of these relapses are already incurable at the time of diagnosis. The aim of the present study was the assessment of time intervals between initial diagnosis of the primary tumor and its relapse. PATIENTS AND METHODS The course of disease of 280 patients was analyzed. RFS was evaluated statistically. RESULTS RFS was strongly related to the location of the primary tumor. The median RFS of patients suffering from oropharyngeal cancer was longer (86 months) than that of patients with hypopharyngeal carcinomas (45 months). Patients with COH revealed an accumulation of recurrent disease within the first 33 months after initial diagnosis. Within the first 2 years more than 60% of COH recurred. After 3 years 80% had developed a relapse.

Abstract
OBJECTIVES Hypopharyngeal squamous cell carcinoma (HPSCC) usually presents at an advanced stage. Although chemoradiotherapy has become more popular in treating HPSCC in recent years, surgery with postoperative adjuvant therapy still plays an important role. The purpose of this study was to identify the clinicopathologic factors that predict survival in patients with HPSCC who underwent surgical treatment. METHODS Between 1986 and 1995, 94 previously untreated HPSCC patients who underwent surgery with or without postoperative radiotherapy were enrolled. The surgical specimens were reexamined by a single pathologist. The clinicopathologic parameters and prognostic data were analyzed. RESULTS With a median follow-up of 50 months, the 5-year overall survival (OS), disease-specific survival (DSS), and relapse-free survival (RFS) were 47%, 60%, and 58%, respectively. Thirty-seven patients (39%) had tumor recurrence. The level of lymph node metastasis was an independent factor in OS, DSS, and RFS. Neck biopsy before surgery, tumor involvement of more than 1 subsite, and extracapsular spread were independent factors in DSS, as was lymphovascular permeation in RFS. CONCLUSIONS The level of cervical lymph node metastasis is the only independent prognostic factor in OS, DSS, and RFS. The addition of postoperative chemoradiotherapy may benefit high-risk cases.

Abstract
CONCLUSIONS The combination of surface-enhanced laser desorption/ionization (SELDI) with bioinformatics tools could help find serum proteome biomarkers and establish a predictive model for early detection of hypopharyngeal squamous cell carcinoma (HSCC). OBJECTIVES Proteomic profiling of serum using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) is an emerging technique to identify new biomarkers in biological fluids and to establish clinically useful diagnostic computational models. We used it to find new potential biomarkers and to establish a predictive model for early detection of HSCC. MATERIALS AND METHODS One hundred serum samples including 48 from HSCC patients and 52 from normal controls which were divided into a training set and a blind testing set were treated on WCX2 and IMAC3 protein chip, and serum protein or peptide patterns were detected by SELDI-TOF-MS. The data of spectra were analyzed by Biomarker Wizard software to screen serum proteome biomarkers of HSCC. A decision tree classification algorithm and blind validation were determined by Biomarker Pattern Software (BPS). RESULTS Ranging from 2 to 30 kDa, 45 potential biomarkers could differentiate HSCC patients from normal controls (p < 0.05). Among them four candidate protein peaks with m/z values of 7796, 4216, 5927, and 5361Da were selected to establish a predictive model by BPS with sensitivity of 94% and specificity of 89%. A sensitivity of 92% and specificity of 82% were validated in the blind testing set.
