Electrochemotherapy for the palliative management of non-skin-origin head and neck cancer: case series and UK national survey.

OBJECTIVES: Electrochemotherapy uses electric fields to facilitate the influx of chemotherapy into cancer cells, producing a targeted effect. For head and neck cancer, it is mainly used for palliation of non-skin-origin metastases. It is used infrequently in the UK. This paper presents our experience and a UK survey to identify its frequency of use. METHODS: Between 2016 and 2019, a prospective database was created and reviewed. Only patients with non-skin-origin metastatic head and neck cancer, with no other palliative options, were included. Survival length, complications and symptomatic benefit were assessed. The survey was conducted via e-mail. RESULTS: Five patients were included: three with squamous cell carcinoma, one with esthesioneuroblastoma and one with hepatocellular carcinoma. Survival ranged from 1 month to over 20 months. Minor complications were seen. Only 15 out of 69 UK head and neck multidisciplinary teams offer electrochemotherapy. CONCLUSION: Electrochemotherapy is a well-tolerated adjunct to standard palliation of metastatic head and neck cancer, and is offered by a limited number of UK multidisciplinary teams.

Curved adjustable fibre-optic diode laser in microscopic cholesteatoma surgery: description of use and review of the relevant literature.

OBJECTIVE: The use of lasers in cholesteatoma surgery is common and well accepted. The most commonly used laser fibres are straight and non-adjustable; these have several limitations. This paper describes the use of an alternative laser fibre. METHOD: This 'How I Do It' paper describes and illustrates the use of an alternative curved adjustable fibre-optic diode laser in microscopic cholesteatoma surgery. RESULTS: The curved, adjustable laser fibre allows accurate and atraumatic disease removal when the use of a straight laser fibre may be less effective or accurate. It reduces potential damage to delicate structures without the need for extra drilling or bone removal. CONCLUSION: It is suggested that the curved adjustable laser fibre is superior to the traditional straight fibre for cholesteatoma surgery.

Laryngomalacia: is there an evidence base for management?

BACKGROUND: The advent of supraglottoplasty clearly has transformed the surgical management of severe laryngomalacia. The condition, however, generally runs a milder course, with spontaneous resolution the norm. OBJECTIVES: To identify gaps in the knowledge and identify topics for future study. METHOD: Systematic review of the literature. RESULTS: The literature suggests that there is a range of abnormalities leading to the typical collapsing upper airway, and that neurological disease, other airway abnormalities, syndromes and gastroesophageal reflux all contribute to disease severity and influence outcomes. The procedures involved in supraglottoplasty are rarely specified, the indications for surgery are vaguely defined and the role of medical therapy is unclear. CONCLUSION: Every review article or survey of opinion suggests that there is still a marked variation in individual practice and a lack of consensus.

Cardiopulmonary exercise testing as a predictor of complications in oesophagogastric cancer surgery.

INTRODUCTION: An anaerobic threshold (AT) of <11 ml/min/kg can identify patients at high risk of cardiopulmonary complications after major surgery. The aim of this study was to assess the value of cardiopulmonary exercise testing (CPET) in predicting cardiopulmonary complications in high risk patients undergoing oesophagogastric cancer resection. METHODS: Between March 2008 and October 2010, 108 patients (83 men, 25 women) with a median age of 66 years (range: 38-84 years) underwent CPET before potentially curative resections for oesophagogastric cancers. Measured CPET variables included AT and maximum oxygen uptake at peak exercise (VO2 peak). Outcome measures were length of high dependency unit stay, length of hospital stay, unplanned intensive care unit (ICU) admission, and postoperative morbidity and mortality. RESULTS: The mean AT and VO2 peak were 10.8 ml/min/kg (standard deviation [SD]: 2.8 ml/min/kg, range: 4.6-19.3 ml/min/kg) and 15.2 ml/min/kg (SD: 5.3 ml/min/kg, range: 5.4-33.3 ml/min/kg) respectively; 57 patients (55%) had an AT of <11 ml/min/kg and 26 (12%) had an AT of <9 ml/min/kg. Postoperative complications occurred in 57 patients (29 cardiopulmonary [28%] and 28 non-cardiopulmonary [27%]). Four patients (4%) died in hospital and 21 (20%) required an unplanned ICU admission. Cardiopulmonary complications occurred in 42% of patients with an AT of <9 ml/min/kg compared with 29% of patients with an AT of ≥9 ml/min/kg but <11 ml/min/kg and 20% of patients with an AT of ≥11 ml/min/kg (p = 0.04). There was a trend that those with an AT of <11 ml/min/kg and a low VO2 peak had a higher rate of unplanned ICU admission. CONCLUSIONS: This study has shown a correlation between AT and the development of cardiopulmonary complications although the discriminatory ability was low.
