RESUMEN
INTRODUCTION: Curative resection of malignant tumours of the skull base is increasingly undertaken endoscopically. Hitherto the diverse histology, rarity and long natural history have made it difficult to accrue statistically robust cohorts for comparison with conventional craniofacial resection. It is now possible to make such a comparison in a large personal cohort. METHOD: Data on all cases of sinonasal malignancy undergoing endoscopic resection with curative intent over an eighteen year period were collected prospectively and analysed for survival and prognostic factors. RESULTS: There were 140 cases, 68 men and 72 women, aged 20-92 years (mean 63 yrs). Follow-up ranged from 6-184 months (mean 60 months). Eighteen different histopathologies were represented with olfactory neuroblastoma (36), malignant melanoma (33) and adenocarcinoma (19) being the commonest. Additional radiotherapy was given in 95 cases and chemotherapy in 49. Overall survival is 84% at 5 years and 69% at 10 years. Overall disease-free survival was 77% at 5 years and 56% at ten. Overall and disease-free survival at 5 (and 10) years is, respectively, 97% and 90% for olfactory neuroblastoma, 79% and 68% for adenocarcinoma and 56% and 39% for malignant melanoma. CONCLUSION: These results show that endoscopic resection is an alternative to conventional craniofacial resection in selected cases.

PURPOSE: Radiotherapy has been the mainstay treatment for nasopharyngeal carcinoma (NPC) and has achieved good disease control. However, irradiation is associated with potential complications such as osteoradionecrosis (ORN) and infection. There is sparse description in the literature of such complications and how they are best managed. The objectives of the study are: (1) to describe the complications at the cervical spine after surgical and radiotherapy treatment for NPC (2) to identify key principles in the diagnosis and treatment of these complications. METHODS: A retrospective review of all patients with cervical spine complications after radiation treatment and surgery for NPC treated in a tertiary referral center, since 1990. RESULTS: Fourteen patients with cervical spine ORN and infections were found with an average duration to diagnosis of 8.6 years. All 14 patients had mucosal and deep biopsies and none had tumor recurrence. Four patients had ORN, eight had osteomyelitis and two patients had both ORN and osteomyelitis. CONCLUSIONS: Radiotherapy complications usually have delayed and subtle presentations. ORN progresses slowly and can often be treated conservatively. Infections should be treated aggressively with surgical debridement and the results are generally good. Patients should be regularly followed-up with transoral examination to assess the integrity of the posterior pharyngeal wall and imaging to assess for ORN. Pharyngeal defects raise concern for cervical spine infections. Coverage of pharyngeal defects in these patients is important to prevent recurrent infection.

OBJECTIVE: To assess the long-term audiological outcome and otological complications of nasopharyngeal carcinoma patients who have received intensity-modulated radiotherapy (IMRT) versus conventional two-dimensional radiotherapy (2 DRT). STUDY DESIGN: Prospective study on the audiological outcome and otological complications 5-9 years after radiotherapy. METHODOLOGY: Patients had pure-tone audiogram before radiotherapy and 5 years after radiotherapy. Otological examination was performed 5-9 years after radiotherapy by an otolaryngologist. RESULTS: There is a significant deterioration of the hearing threshold 5 years after radiotherapy but there is no statistically significant difference in the deterioration of hearing between IMRT and 2 DRT. Six patients in the 2 DRT group and 1 patient in the IMRT group had osteoradionecrosis of the external auditory canal (p = 0.042). CONCLUSION: There are fewer incidences of osteoradionecrosis of the external auditory canal in patients treated with IMRT. There is no difference in bone conduction threshold in patients treated with IMRT or 2 DRT.

BACKGROUND: We have previously reported our early experience in robotic-assisted nasopharyngectomy. The current case series is a report of our experience in 33 robotic-assisted nasopharyngectomy. METHODS: Prospective series of patients who underwent robotic-assisted nasopharyngectomy for local recurrent nasopharyngeal carcinoma from January 2010 to March 2019. RESULTS: Thirty-one patients underwent robotic-assisted nasopharyngectomy with two additional second procedure for positive margin. Median age is 55 years (29-85). Twenty-five patients had rT1 disease and six patients had tumor invaded sphenoid floor (rT3). Median operative time was 227 min and median blood loss was 200 ml. The median follow-up period for all patients were 38 months. Four patients had local recurrence. Five-year local control rate, overall survival, and disease-free survival are 85.1%, 55.7%, and 69.1%, respectively. CONCLUSION: Robotic-assisted nasopharyngectomy for recurrent nasopharyngectomy was showed to have a high local control rate. The operating time was comparable to open surgery.

BACKGROUND: Pharyngo-laryngo-esophagectomy (PLE) has been regarded as a standard treatment for cervical esophageal cancer, but the morbidity and mortality rates associated with PLE are substantial. Chemoradiation (CTRT) is widely used to treat esophageal cancer; however, its role in managing cervical esophageal cancer has not been fully elucidated. It was hypothesized that up-front CTRT could be an effective alternative treatment option to PLE. The purpose of this study was to compare the outcomes of patients with cervical esophageal cancer treated with these two methods. METHODS: Patients with cervical esophageal cancer from 1995 to 2008 were studied. Three main groups were identified: those treated with PLE, those managed with up-front concurrent chemoradiation, and those not suitable for either PLE or chemoradiation but to whom palliative treatment was offered. The demographics, management strategies, and outcomes of these patients were studied and analyzed. RESULTS: A total of 107 patients were studied: 87 (81.3%) were men, and the median age was 64 years (range 17-92 years). There were 62 patients who underwent PLE as the primary treatment, 21 had up-front chemoradiation, and the others had palliative treatment. In the PLE group, curative resection was achieved in 37 (59.7%) patients, 20 of whom had either adjuvant chemoradiation or radiotherapy. The hospital mortality rate was 7.1%. In the chemoradiation group, 10 (47.6%) had tumor down-staging, 6 of whom achieved a clinically complete response. Among the 11 patients with poor response, 5 required salvage PLE for palliation. Chemoradiation-associated morbidities included oral mucositis, bilateral vocal cord palsy, esophageal stricture, carotid artery blowout, and permanent hypothyroidism and hypoparathyroidism. The median survival durations of patients in the PLE and chemoradiation groups were 20 and 25 months respectively (P = 0.39). CONCLUSIONS: Up-front chemoradiation can be an alternative therapeutic strategy to PLE. However, this method is not without drawbacks. A significant proportion also requires salvage surgery. Both PLE and chemoradiation have significant curative as well as palliative role in the management of cervical esophageal cancer and treatment should be individualized.

BACKGROUND & AIMS: There is controversy about the efficacy of treating patients with laryngopharyngeal reflux (LPR) using proton pump inhibitors (PPIs). We assessed the effects of high doses of the PPI rabeprazole in patients with LPR. METHODS: Patients with LPR symptoms were assigned randomly to receive rabeprazole (20 mg, twice daily, n = 42) or placebo (n = 40) for 12 weeks. All patients completed symptom questionnaires; these provided demographic information and the reflux symptom index before, during, and 6 weeks after cessation of treatment. Videolaryngostroboscopy was used to document the laryngeal findings and determine the reflux finding score. RESULTS: Twenty-four patients (57.1%) in the rabeprazole group and 27 patients (67.5%) in the placebo group had pH-documented LPR. The total reflux symptom index score decreased significantly in the group given rabeprazole, compared with patients given placebo, at weeks 6 and 12, but not at week 18. However, there were no significant differences in reflux finding scores between the rabeprazole and placebo groups at any of the time points. CONCLUSIONS: Twelve weeks of treatment with rabeprazole (20 mg, twice daily) significantly improved reflux symptoms, compared with placebo, in patients with LPR. Relapse of symptoms was observed 6 weeks after stopping PPI therapy, indicating the requirement for longer treatment duration in patients with LPR.

It is not uncommon for patients with hypopharyngeal cancer to present at an advanced stage of disease. Surgical treatment provides a cure for the tumour with immediate relief from obstruction to the airway and the swallowing passage. Careful planning of surgery is important to ensure good outcome of treatment and prevent complications, some of which may be fatal. The shape of the hypopharynx resembles that of a funnel, with a wide circumference above in continuity with the oropharynx, and a small circumference below where it joins with the cervical oesophagus. As a result, while small tumours require the partial removal of the hypopharynx, large tumours, especially those involving the post-cricoid region, warrant a complete, circumferential pharyngectomy. For tumours that invade the cervical esophagus, transcervical approach is still feasible, and this is facilitated by the removal of the manubrium, allowing access to the tumour and resection with clear margins. In the presence of synchronous tumours lower down in the esophagus, pharyngo-laryngo-esophagectomy is indicated. Successful reconstruction of defects after tumour extirpation allows proper wound healing and early delivery of adjuvant radiotherapy. It is also important to ensure quick recovery of the long-term swallowing function. It ranges from the use of the soft tissue flap with skin island that is sutured as a patch to the remnants of the pharyngeal mucosa, to the use of a visceral flap, such as the free jejunal flap, to repair the circumferential pharyngectomy defects. The treatment protocol is personalized according to the extent of the tumour and the characteristics of the patients.

OBJECTIVE: We analyzed a single center's experience over a decade of right liver living donor liver transplantation (RLDLT). SUMMARY BACKGROUND DATA: To define the donor risk and recipient benefit ratio, midterm outcome of this life-saving treatment modality ought to be known. METHODS: Consecutive patients from 9 May 1996 were included. Era I comprised the first 50 patients and Era II comprised the remaining 184 patients. Their midterm outcomes were compared with patients receiving deceased donor liver transplantation (DDLT) of the same period in the same center. RESULTS: With a median follow-up of 48 months, the 1-, 3-, and 5-year overall survival rates were 93.2%, 85.7%, and 82.4%, respectively and were comparable with those of DDLT (n = 131) (90.1%, 87.7%, and 85.2%) (P = 0.876). Hospital mortality decreased from 16% in Era I to 2.2% in Era II (P = 0.000). Reduced hospital mortality improved the overall survival rates from Era I to Era II (78%, 74%, and 72% vs. 97.3%, 88.7%, and 85.1%, respectively) (P = 0.003). The 5-year survival rate of recipients with hepatocellular carcinoma (HCC) (n = 65) was 65.7%. Starting from Era II, excellent 5-year survival of recipients without HCC was achieved as compared with DDLT in the same period (93.4% vs. 88.2%) (P = 0.493). The 5-year survival rates of recipients with HCC within the Milan criteria of Era II and DDLT in the same period were 72.0% and 100%, respectively (P = 0.091). Multivariate analysis indicated that only Era I (relative risk = 2.606; P = 0.005) and pretransplant HCC (relative risk = 2.729; P = 0.002) adversely affected overall survival. CONCLUSIONS: High midterm survivals were achieved by reduction of hospital mortality through accumulation of experience and transplanting recipients with low chance of recurrence of HCC. RLDLT could be considered as a legitimate alternative to DDLT.

BACKGROUND: The presence of synchronous or antecedent head and neck cancers may complicate management of patients with primary esophageal cancer. METHODS: From January 1982 to December 2004, by means of a prospectively collected database, we compared information from 119 patients with esophageal cancers who had synchronous or antecedent head and neck cancers with information from 1555 patients who only had squamous cell esophageal cancer in a tertiary referral academic hospital. RESULTS: There were far more men and younger patients in those who had head and neck cancers, and multicentric tumors were also more common. Hypopharyngeal tumors were the most frequently encountered head and neck cancer and were found in 36.1% of patients. Resection rates of the primary esophageal cancers were similar in those who had head and neck cancers and in those who only had esophageal cancer (60.7% vs. 61.7% P = .74). Overall postoperative complication rates were not different. Thirty-day mortality rates were 0% and 2.9% for those who did and did not have head and neck tumors, respectively (P = .25). The respective hospital mortality rates were 10.3% and 9.5% (P = .83). Median survival for resectable esophageal cancers was 9.2 months for the former group and 13.4 months for the latter (P = .02). CONCLUSIONS: Esophagectomy rates did not differ when synchronous or antecedent head and neck cancers were present. Similar postoperative morbidity and mortality rates could be achieved. The presence of additional head and neck tumors imparted a worse long-term prognosis.

BACKGROUND: Capecitabine monotherapy had activity in recurrent/metastatic nasopharyngeal carcinoma (NPC) as demonstrated previously in a small pilot study. We conducted a retrospective review of patients who received capecitabine for recurrent and metastatic NPC to further evaluate its clinical benefits. METHODS: Forty-nine patients with recurrent and metastatic NPC received capecitabine at a dose of 1-1.25 G/m(2) twice daily for 14 days in 3-week cycles. Disease sites were locoregional in 29%, distant in 45% and locoregional plus distant in 26%. All except one had prior platinum-based chemotherapy for relapse or as adjunctive treatment. Median follow-up was 10 months (range: 3-41). RESULTS: Treatment was generally well tolerated. Hand-foot syndrome was common and occurred in 86% (25% Grade 3). Grade 3 hematological toxicity occurred in 6%. Partial response rate was 31% (95% CI: 18%, 44%) and complete response rate was 6% (95% CI: 0%, 13%), for an overall response rate of 37% (95% CI: 23%, 50%). Median time-to-progression was 5 months and median survival was 14 months. One- and two-year survival rates were 54 and 26%, respectively. Significantly better survival was observed in patients treated for locoregional recurrence and those with severe hand-foot syndrome. CONCLUSIONS: Capecitabine has single agent activity in NPC and severe hand-foot syndrome predicts favorable outcome. Based on our experience, capecitabine monotherapy should be considered in patients with recurrent/metastatic NPC.

BACKGROUND: Similar to the radial forearm flap, free tissue transfer of a fasciocutaneous flap is possible if the septocutaneous perforators of the posterior tibial vessels are preserved. OBJECTIVE: The authors report their clinical experience on using the free posterior tibial flap for primary reconstruction of head and neck defects after tumor extirpation. METHODS: Eleven patients were included between October of 2005 and March of 2007. Patients' clinical and demographic data were collected. The flap harvesting results and outcomes were retrospectively reviewed. Representative cases are presented for illustration. RESULT: There were nine men and two women, and their ages ranged from 34 to 83 (mean, 60.3) years. The flaps measured from 6 x 9 cm to 8 x 12 cm. Two cutaneous perforators were included in the majority of cases. The average flap thickness was 0.7 cm, and the average pedicle length was 14 cm. Flap survival was 100%. Skin grafts of all donor sites healed well. All patients were ambulatory early in the postoperative period, and there was no distal limb ischemia or cold intolerance on follow-up. Four patients needed postoperative adjuvant radiotherapy. CONCLUSION: Our study demonstrates that the posterior tibial flap is a safe and reliable flap for reconstruction of head and neck defects after tumor expiration. It has all the comparable properties of a radial forearm flap. In addition, a larger area of skin can be removed, and the graft donor site is less conspicuous.

OBJECTIVE: To evaluate anterolateral thigh flap shrinkage after elevation and to develop a predictive model for flap design. METHOD: A prospective study was conducted in a university teaching hospital. The skin islands from anterolateral thigh flaps were outlined on a transparent sheet before and after the reconstruction procedure. Dimensions of the stretched flaps were also recorded. These three outlines were scanned and the surface areas computed and compared by tracing and use of AutoCAD. Age, sex, flap dimension, and flap thickness were investigated for association with flap shrinkage. RESULTS: Forty-five anterolateral thigh flaps harvested for head and neck soft tissue reconstruction after tumor resection were studied. Flap size ranged from 4 to 14 cm in width and 8 to 22 cm in length; flap area ranged from 30.6 to 151.0 cm. On average, the flaps shrunk by 25.0% (6.2%-52.6%), a highly significant change (P < .01). Flap width and thickness correlated with the reduction in flap size. The average stretched-flap area was 10.1% (0.4%-29.4%) less than the preflap area, a significant reduction (P < .01). The difference between stretched-flap and preflap areas was independent of all variables. We developed a predictive model using a stepwise multiple linear regression method with a coefficient of determination of 0.495. CONCLUSIONS: Anterolateral thigh flaps shrink after harvesting, and flap width and thickness are significant contributing variables. These findings indicate that flap size must take shrinkage into account to ensure sufficient coverage.

OBJECTIVES: To review the treatment outcome of rhabdomyosarcoma in Hong Kong Chinese children. DESIGN: Retrospective review. SETTING: University teaching hospital, Hong Kong. PATIENTS: Consecutive cases of rhabdomyosarcoma diagnosed and treated by the Department of Paediatrics and Adolescent Medicine of Queen Mary Hospital between 1989 and 2005. Each patient was staged and treated according to the Intergroup Rhabdomyosarcoma Study guidelines. MAIN OUTCOME MEASURES: Overall and event-free survival rates, and toxicity data. RESULTS: Of 19 patients (8 males and 11 females), 14 (74%) were younger than 10 years old. The median age at diagnosis was 6 (range, 0.5-17) years. Primary sites of rhabdomyosarcoma included: the head and neck (n=8; 6 classified as cranial parameningeal), genitourinary (3), extremity (3), pelvis (3), and trunk (2). Thirteen (68%) had embryonal and six (32%) had alveolar histology. Two, 2, 9, and 6 were classified as belonging to Intergroup Rhabdomyosarcoma Study groups 1, 2, 3, and 4, respectively. Respective 5-year overall and event-free survival rates of the entire cohort were 49% (95% confidence interval, 26-73%) and 32% (10-55%), with a median follow-up of 3.4 (range, 0.2-16.7) years. In non-metastatic cases (Intergroup Rhabdomyosarcoma Study groups 1-3), the 5-year overall survival rate was 66% (95% confidence interval, 39-93%) and in metastatic cases (group 4) it was 17% (0-46%). The 5-year overall survival rate for patients aged less than 10 years was 60% (95% confidence interval, 33-87%) compared to 20% (0-55%) in those aged 10 years and over. Significant treatment-related toxicities including myelosuppression, infections, peripheral neuropathy, and second cancers were encountered. CONCLUSIONS: Treatment outcome of rhabdomyosarcoma in this cohort of Chinese children was less favourable than that reported in international studies. Whilst the main reason could have been related to the high proportion of metastatic cases, also non-metastatic cases faired worse. Improved outcomes may be achieved by advances in multidisciplinary (paediatric oncology, pathology, radiotherapy, and surgery) management and supportive care.

BACKGROUND: Limited local failure of nasopharyngeal carcinoma (NPC) can often be salvaged by reirradiation using different techniques. Both gold grain implantation (GGI) and stereotactic radiosurgery (SRS) have been used as salvage treatment of NPC but the relative efficacy of these two treatments is not known. METHODS AND MATERIALS: A total of 74 patients with local NPC failure were included in this retrospective analysis. Of these patients, 37 underwent SRS (median dose, 12.5 Gy) and 37 split-palatal GGI at a dose of 60 Gy. The two groups were individually matched for prognostic factors, except for tumor volume. The median follow-up was 42 months. RESULTS: Local control was better in the GGI group. The 3-year local failure-free rate was 77.9% for the GGI group compared with 68.3% for the SRS group. However, the difference was not statistically significant (p = 0.098). In the subgroup with a tumor volume of Asunto(s)

RESUMEN
PURPOSE OF REVIEW: The management of cervical lymph node metastases in nasopharyngeal carcinoma is important for a favourable outcome. The strategy of diagnosis and treatment for the lymph nodes on presentation and those that have recurred after initial therapy are different. This review presents the current concept. RECENT FINDINGS: The detection of the cervical lymph node metastases on presentation has improved with magnetic resonance imaging and positron emission tomography. The confirmation of the presence of malignancy is through fine needle aspiration cytology. For those lymph nodes that have recurred after concurrent radiotherapy and chemotherapy, the progression of the nodes detected through clinical examination and imaging studies indicates that salvage therapy is necessary. The surgical procedure of salvage is radical neck dissection, as pathological studies have shown that these lymph nodes exhibit extensive involvement of the neck tissue. Postoperative brachytherapy should be applied when the deep resection margins are close. SUMMARY: Identification of lymph node metastasis provides accurate staging of the disease and radical surgery should be performed for salvage.

OBJECTIVE: To justify the application of medialization thyroplasty in Chinese patients with symptomatic cancer-related unilateral vocal fold paralysis (UVFP). STUDY DESIGN AND SETTING: Retrospective chart review from February 2000 to March 2006. RESULTS: Eighty-seven Chinese patients undergoing medialization thyroplasty for UVFP were included; there were no significant differences between the cancer-related and benign groups in terms of the speech and swallowing rehabilitation outcome and the perioperative complication rate (P > 0.05). The median survival time of cancer-related UVFP patients from the date of medialization to death was 129 days. Age more than 65 years was identified as the only factor for a shorter survival period after medialization (P = 0.040). CONCLUSION: Medialization thyroplasty restores satisfactory speech and swallowing and has a low perioperative complication rate in Chinese patients with cancer-related UVFP. Postmedialization survival period was also reasonable. SIGNIFICANCE: Medialization thyroplasty is a justifiable treatment option for cancer-related UVFP.

Improved hygiene and public awareness have led to a steady decline in the incidence of pulmonary tuberculosis in developed countries. Nonetheless, long-term sequelae like unilateral vocal fold paralysis should not be underestimated in a modern society. We report three patients with chronic lung fibrosis following pulmonary tuberculosis leading to unilateral vocal fold paralysis. All three patients had hoarseness and chronic aspiration on swallowing. Early diagnosis and prompt surgical intervention are essential if this potentially fatal complication is to be prevented.

Incidence of nasopharyngeal carcinoma has remained high in endemic regions. Diagnosing the disease in the early stages requires a high index of clinical acumen and, although most cross-sectional imaging investigations show the tumour with precision, confirmation is dependent on histology. Epstein-Barr virus (EBV)-encoded RNA signal is present in all nasopharyngeal carcinoma cells, and early diagnosis of the disease is possible through the detection of raised antibodies against EBV. The quantity of EBV DNA detected in blood indicates the stage and prognosis of the disease. Radiotherapy with concomitant chemotherapy has increased survival, and improved techniques (such as intensity-modulated radiotherapy), early detection of recurrence, and application of appropriate surgical salvage procedures have contributed to improved therapeutic results. Screening of high-risk individuals in endemic regions together with developments in gene therapy and immunotherapy might further improve outcome.

For patients with squamous cell carcinoma of the upper aerodigestive tract, appropriate management of the regional lymph nodes is an important and often controversial issue that has significant influence on survival. Over the years radical treatment either by surgery or radiotherapy contributed to improvement in prognosis. Recently, a more conservative approach has achieved a similar level of cancer control with less morbidity. This review considers the issues of selection of patients for treatment of the neck, choice of modality and extent of therapy, treatment of the contralateral neck, management of recurrence and influence of the site and status of the primary lesion.

OBJECTIVES/HYPOTHESIS: Recent developments in voice assessment propose the use of quality of life measurements. The Voice Handicap Index (VHI) is one of the most psychometrically robust and well-studied instruments among the various instruments for measuring quality of life. Two versions of VHI (VHI-30 and VHI-10) have been shown to be valid instruments for distinguishing dysphonic from nondysphonic individuals and also for documenting treatment effect for dysphonic patients. The VHI has been used worldwide; however, the psychometric properties of the Chinese version of VHI remains untested. This study aimed to investigate such properties of the Chinese VHI-30 and VHI-10 in the Hong Kong Chinese population. STUDY DESIGN: Psychometric analysis of the Chinese VHI-30 and VHI-10 in dysphonic patients and control subjects. METHODS: The original VHI-30 was translated into Chinese and was completed by 131 dysphonic patients and 54 nondysphonic individuals. The dysphonic patients also self-rated their dysphonic severity. RESULTS: Results showed high test-retest reliability and high item-total correlation for both Chinese VHI-30 and VHI-10. Both Chinese versions could be used to distinguish different dysphonic groups and between dysphonic and nondysphonic groups. Significant correlation was found between the VHI scores and the patients' self-rated dysphonic severity. CONCLUSION: The present study supported the original three-factorial structures of the VHI-30 and the use of the VHI for the Chinese population. It is shown that the Chinese VHI-10 is a strong representation of VHI-30 and is recommended for use in clinics because of its validity and ease of use by patients.
