Radiotherapy versus open surgery versus endolaryngeal surgery (with or without laser) for early laryngeal squamous cell cancer.

BACKGROUND: This is an update of a Cochrane review first published in The Cochrane Library in Issue 2, 2002 and previously updated in 2004, 2007 and 2010.Radiotherapy, open surgery and endolaryngeal excision (with or without laser) are all accepted modalities of treatment for early-stage glottic cancer. Case series suggest that they confer a similar survival advantage, however radiotherapy and endolaryngeal surgery offer the advantage of voice preservation. There has been an observed trend away from open surgery in recent years, however equipoise remains between radiotherapy and endolaryngeal surgery as both treatment modalities offer laryngeal preservation with similar survival rates. Opinions on optimal therapy vary across disciplines and between countries. OBJECTIVES: To compare the effectiveness of open surgery, endolaryngeal excision (with or without laser) and radiotherapy in the management of early glottic laryngeal cancer. SEARCH METHODS: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL 2014, Issue 8); PubMed; EMBASE; CINAHL; Web of Science; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 18 September 2014. SELECTION CRITERIA: Randomised controlled trials comparing open surgery, endolaryngeal resection (with or without laser) and radiotherapy. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We identified only one randomised controlled trial, which compared open surgery and radiotherapy in 234 patients with early glottic laryngeal cancer. The overall risk of bias in this study was high.For T1 tumours, the five-year survival was 91.7% following radiotherapy and 100% following surgery and for T2 tumours, 88.8% following radiotherapy and 97.4% following surgery. There were no significant differences in survival between the two groups.For T1 tumours, the five-year disease-free survival rate was 71.1% following radiotherapy and 100.0% following surgery, and for the T2 tumours, 60.1% following radiotherapy and 78.7% following surgery. Only the latter comparison was statistically significant (P value = 0.036), but statistical significance would not have been achieved with a two-sided test.Data were not available on side effects, quality of life, voice outcomes or cost.We identified no randomised controlled trials that included endolaryngeal surgery. A number of trials comparing endolaryngeal resection and radiotherapy have terminated early because of difficulty recruiting participants. One randomised controlled trial is still ongoing. AUTHORS' CONCLUSIONS: There is only one randomised controlled trial comparing open surgery and radiotherapy but its interpretation is limited because of concerns about the adequacy of treatment regimens and deficiencies in the reporting of the study design and analysis.

Continuing clopidogrel during elective total hip and knee arthroplasty: assessment of bleeding risk and adverse outcomes.

Limited research assessing risks of continued clopidogrel perioperatively in patients undergoing elective orthopedic procedures exists. Patients that underwent elective primary or revision total knee arthroplasty (TKA) or total hip arthroplasty (THA) from 2007 to 2012 while taking clopidogrel at the time of surgical evaluation were retrospectively identified. Patient demographics, last dose of clopidogrel, intraoperative blood loss, blood transfusion, and presence of 30-day adverse cardiac events (ACE) were collected. Of 142 patients meeting criteria, 24 (16.9%) patients remained on clopidogrel perioperatively. Patients that continued clopidogrel were more likely to receive a blood transfusion within 24 hours of surgery (31.8% vs. 7.7%; P=0.004) and during hospitalization (37.5% vs. 15.3%; P=0.02), but the incidence of 30-day ACE was not significantly different. Continuation of clopidogrel perioperatively for elective THA or TKA should be carefully considered.

Anaplastic thyroid cancer: the addition of systemic chemotherapy to radiotherapy led to an observed improvement in survival--a single centre experience and review of the literature.

INTRODUCTION: Anaplastic thyroid carcinoma (ATC) is rare yet accounts for up to 50% of all thyroid cancer deaths. This study reviews outcomes of patients with confirmed ATC referred to a tertiary oncology centre plus reviews the literature to explore how poor outcomes may be improved. MATERIALS AND METHODS: The management and outcomes of 20 patients with ATC were reviewed. RESULTS: Median age at diagnosis was 69.5 years. 19 patients died due to ATC, 40% of whom died from asphyxiation. Median survival for all cases was 59 days. Patients who had previous surgery prior to other treatment modalities had a longer median survival overall compared to those who had not had previous surgery (142 days compared to 59 days) and produced the one long-term survivor. Chemotherapy followed by radiotherapy (without previous surgery) was associated with longer median survival (220 days). Palliative radiotherapy alone did not decrease the rate of death by asphyxiation when compared to other single modality treatments. CONCLUSION: Multimodality treatment including surgery when feasible remains the best strategy to improve survival and prevent death from asphyxiation in the management of ATC. The addition of chemotherapy to our institutional protocol led to improved survival but prognosis remains very poor.

Does patient-perceived handicap correspond to the modified clinical test for the sensory interaction on balance?

OBJECTIVE: To determine whether patient self-reported handicap correlates with scores obtained from the modified Clinical Test for the Sensory Interaction on Balance as assessed by the Neurocom VSR Balance Master platform. STUDY DESIGN: Prospective observational. SETTING: Balance clinic in tertiary referral center. PATIENTS: Patients referred with dizziness or imbalance as their primary complaint. OUTCOME MEASURES: The modified Clinical Test for the Sensory Interaction on Balance scores as assessed by the Neurocom VSR Balance Master platform, the Dizziness Handicap Inventory, and the Health Utilities Index Marks 2 and 3. RESULTS: One hundred fifty-nine patients were entered into the study. The mean age of participants was 54.5 years, with a female-to-male ratio of 2.1:1. The scores for the Dizziness Handicap Inventory and Health Utilities Index are similar between sexes, and although the Dizziness Handicap Inventory score did not correlate with age, Health Utilities Index 2 and 3 scores did show a negative correlation with increasing age. There are weak, positive correlations between the Dizziness Handicap Inventory and the firm surface conditions of the modified Clinical Test for the Sensory Interaction on Balance but no useful correlation with the foam conditions. Similar weak negative correlations were found between the Health Utilities Index 2 and 3 and the modified Clinical Test for the Sensory Interaction on Balance scores. CONCLUSION: Patient-perceived handicap of imbalance appears to correlate poorly with assessment of postural stability using the modified Clinical Test for the Sensory Interaction on Balance.

Nasal polyposis: prevalence of positive food and inhalant skin tests.

OBJECTIVES: To investigate the etiology of nasal polyps and its relationship to allergy. The prevalence of positive food and inhalant skin tests in patients with nasal polyps and nonatopic controls was compared. STUDY DESIGN AND SETTING: Prospective controlled study in tertiary referral rhinology clinic. RESULTS: Seventy percent (70%) of the patients with nasal polyps had positive skin tests to an average of four foodstuffs, compared to 34 percent of controls (P = 0.006). Only 35 percent of the nasal polyp patients also had positive inhalant skin tests. Overall, the prevalence of positive inhalant skin tests was similar in the nasal polyp patients and controls. CONCLUSIONS: These findings suggest that the positive skin tests to foods are not merely a reflection of the general atopic status of patients with nasal polyps. It may be that non-IgE-mediated hypersensitivities, such as to ingested foods, play a role on the basis of a significant number of patients with positive intradermal skin tests to foods. SIGNIFICANCE: Evaluation of the allergic status of patients with polyposis is important. Dietary manipulation may be indicated, though its role needs further investigation.

Management of the compromised airway and role of tracheotomy in anaplastic thyroid carcinoma.

BACKGROUND: Anaplastic thyroid carcinoma (ATC) is an uncommon thyroid malignancy with a poor prognosis. American Thyroid Association (ATA) guidelines acknowledge the complexity of airway management in these patients. We studied our local experience with the aim of providing guidance in airway management in ATC. METHODS: Patients with histologically confirmed ATC from January 2004 to December 2011 were identified from our institutional database. The data were retrospectively analyzed using hospital case notes. RESULTS: Twenty-six patients were identified with ATC, 25 of who died from the disease. Five of 26 patients (19%) had stridor at presentation. A further 6 of 26 patients (23%) developed stridor during or soon after radiotherapy. Nine patients (36%) died of airway obstruction. CONCLUSION: Tracheotomy can facilitate completion of palliative treatment in those patients with ATC and stridor. Given the short life expectancy of these patients, a balanced decision must be made regarding the role and timing of tracheotomy.

A prospective randomized single-blind trial comparing ultrasonic scalpel tonsillectomy with tonsillectomy by blunt dissection in a pediatric age group.

OBJECTIVE: To determine if there was a difference in postoperative pain and dietary intake when comparing ultrasonic scalpel (US) with blunt dissection tonsillectomy (BD) in children. STUDY DESIGN AND SETTING: A prospective single-blind randomized controlled trial comparing US and BD tonsillectomy in children aged between 5 and 13 years who undergo tonsillectomy for recurrent acute tonsillitis in a specialized pediatric hospital. RESULTS: One hundred and twenty-two children were enrolled. Ninety-three (76%) patients completed dietary and pain scales. Pain was significantly greater in the US group on postoperative days 1 and 3 (P = 0.0466, P = 0.0084) and overall (P = 0.0003). Dietary intake scores were significantly better in the US group on days 1, 5, 7, and 9, however, these scores were inconsistent with dietary intake scores declining in both groups throughout the study. Blood loss was statistically significantly greater in the BD group (33.1 ml vs 3.0 ml, P < 0.0001). There were no significant differences for all other observed outcomes. CONCLUSIONS: US tonsillectomy causes significantly more pain overall and on postoperative days 1 and 3 when compared to BD tonsillectomy. US tonsillectomy causes less intraoperative blood loss, the clinical significance of which is questionable. SIGNIFICANCE: US tonsillectomy appears to cause more postoperative pain than BD tonsillectomy in children aged 5 to 13 years undergoing tonsillectomy for recurrent acute tonsillitis.

Central nervous system abnormalities in Fanconi anaemia: patterns and frequency on magnetic resonance imaging.

OBJECTIVE: Fanconi anaemia (FA) is an inherited disease associated with congenital and developmental abnormalities resulting from the disruption of a multigenic DNA damage response pathway. This study aimed to define the MRI appearances of the brain in patients with FA in correlation with their genetic and clinical features. METHODS: A review of the brain MRI in 20 patients with FA was performed. Pituitary size and frequencies of the radiological findings of individuals with FA and age-matched controls were determined. RESULTS: Abnormalities were identified in 18 (90%) patients with FA, the commonest being a small pituitary (68%, p < 0.01 females and p < 0.001 males). In five cases (25%, p = 0.02), the pituitary morphology was also abnormal. Posterior fossa abnormalities were seen in six cases (30%, p = 0.01) including Chiari I malformation (n = 3), Dandy-Walker variant (n = 2) and cerebellar atrophy (n = 2). Six patients (30%, p = 0.01) had morphological structural variation of the corpus callosum (CC). CONCLUSION: The incidence of central nervous system (CNS) abnormalities in FA is higher than previously reported, with a midline predominance that points to impact in the early stages of CNS development. MRI brain imaging is important for endocrine assessment and pre-transplant evaluation and can make an important contribution to clinical decision-making. ADVANCES IN KNOWLEDGE: The incidence of brain structural abnormalities in FA is higher than previously reported, with abnormalities of the posterior fossa, CC and pituitary being common. There is an association with gender and reduction in pituitary size which does not strongly correlate with biochemically evident endocrine abnormality.

Use of Pre-Ablation Radioiodine-131 Scan to Assess the Impact of Surgical Volume and Specialisation following Thyroidectomy for Differentiated Thyroid Carcinoma.

BACKGROUND: We evaluated the relationship between thyroid remnant size following thyroidectomy for differentiated thyroid carcinoma and surgical volume and specialisation by assessing pre-ablation radioiodine-131 ((131)I) thyroid bed uptake (TBU) scanning as a surrogate for residual thyroid tissue. METHODS: We analysed data of 651 patients in our thyroid cancer database. Patients' data were included if the following criteria were met: (1) diagnosis of differentiated thyroid carcinoma, (2) total or near-total thyroidectomy, (3) pre-ablation (131)I scan prior to radioiodine ablation (RAI), (4) no distant metastasis, and (5) >3,000 MBq ablative dose of (131)I. (131)I diagnostic whole-body scans and measurement of thyroglobulin levels were carried out 3-9 months after RAI. 305 patients were included in the final analysis. RESULTS: Four endocrine, 19 otolaryngology and 25 general surgeons performed thyroidectomies with median pre-ablation (131)I TBU values of 1.0, 1.8 and 2.9%, respectively (p = 0.0031). There was a statistically significant relationship between number of thyroidectomies performed and median pre-ablation (131)I TBU values up to the optimal number of 11 operations beyond which there was no further significant difference between surgeons. There were differences in remnant size between endocrine and general surgeons (p = 0.001), otolaryngology and general surgeons (p = 0.023) but not between endocrine and otolaryngology surgeons (p = 0.167). CONCLUSION: Using the pre-ablation (131)I uptake scan as a surrogate for thyroid remnant quantification following thyroidectomy demonstrates the relationship between the surgical volume and size of thyroid remnant. The study also demonstrated beneficial effects of specialisation with specialist surgeons achieving the smallest thyroid remnant.

Audit of clinical coding of major head and neck operations.

INTRODUCTION: Within the NHS, operations are coded using the Office of Population Censuses and Surveys (OPCS) classification system. These codes, together with diagnostic codes, are used to generate Healthcare Resource Group (HRG) codes, which correlate to a payment bracket. The aim of this study was to determine whether allocated procedure codes for major head and neck operations were correct and reflective of the work undertaken. HRG codes generated were assessed to determine accuracy of remuneration. PATIENTS AND METHODS: The coding of consecutive major head and neck operations undertaken in a tertiary referral centre over a retrospective 3-month period were assessed. Procedure codes were initially ascribed by professional hospital coders. Operations were then recoded by the surgical trainee in liaison with the head of clinical coding. The initial and revised procedure codes were compared and used to generate HRG codes, to determine whether the payment banding had altered. RESULTS: A total of 34 cases were reviewed. The number of procedure codes generated initially by the clinical coders was 99, whereas the revised codes generated 146. Of the original codes, 47 of 99 (47.4%) were incorrect. In 19 of the 34 cases reviewed (55.9%), the HRG code remained unchanged, thus resulting in the correct payment. Six cases were never coded, equating to pound15,300 loss of payment. CONCLUSIONS: These results highlight the inadequacy of this system to reward hospitals for the work carried out within the NHS in a fair and consistent manner. The current coding system was found to be complicated, ambiguous and inaccurate, resulting in loss of remuneration.
