Endobronchial laser ablation in the management of epithelial-myoepithelial carcinoma of the trachea

AbstractA 52 year old, never smoker presented to hospital with progressive shortness of breath and significant stridor over a five month period. He also described the feeling of needing to cough but being unable to expectorate. CT Thorax demonstrated a mass lesion in the trachea just distal to the larynx which was then confirmed on rigid bronchoscopy. Subsequent histology confirmed an epithelial-myoepithelial carcinoma.Only a few case reports document these rare salivary gland tumours occurring in other locations such as the respiratory tract. After staging showed only local disease, the patient was managed with rigid bronchoscopy and laser ablation therapy.We present the first documented case to be treated with endobronchial laser ablation therapy with discussion of the incidence, presentation and characteristics of these tumours including the treatment options, as well as the use of laser ablation in the management of benign and malignant endobronchial lesions

Simultaneous cardiac surgery with pulmonary resection: presentation of series and review of literature 1

Abstract Background: The issue of performing simultaneous pulmonary resection and cardiac surgery in patients with coexisting lung carcinoma and ischaemic heart disease remains controversial. We report our experience and review the literature. Methods: Thirteen patients (male ten, female three; mean age 65 years) underwent simultaneous cardiac surgery and pulmonary resection. Lung pathology consisted of primary lung carcinoma (n = 10), benign disease (n = 2) and carcinoid (n = 1). Lung resections included pneumonectomy (n = 3), lobectomy (n = 4), segmentectomy (n = 1) and local excision (n = 5). Cardiac procedures consisted of coronary artery bypass grafting (CABG) in 11, aortic valve replacement in one and mitral valve repair with CABG in one patient. In all but one case the lung resection was performed prior to heparinization and cardiopulmonary bypass (CPB). In two patients, with suitable coronary anatomy, myocardial revascularization without CPB was performed to reduce morbidity. Results: There was no hospital mortality. Postoperative blood loss and ventilation requirements were reduced in the patients who were operated on without CPB. Prolonged ventilatory support was required in two cases. All patients with benign pathology are alive. In the lung cancer group there have been five late deaths: disseminated metastatic disease (n = 3), anticoagulant related haemorrhage (n = 1) and broncho-pleural fistula (n = 1). Of the remaining five patients four are alive and disease free 7-23 months post-operatively; one patient has recurrent disease 40 months post-operatively. Conclusions: Simultaneous pulmonary resection and cardiac surgery is associated with acceptable operative morbidity and mortality. In patients with lung carcinoma long-term survival was determined by tumour stage. The avoidance of CPB may be advantageous by decreasing blood loss and ventilation requirements

Inability to perform maximal stair climbing test before lung resection: a propensity score analysis on early outcome

Abstract Objective: The objective of the present study was to assess whether patients unable to perform a preoperative maximal stair climbing test had an increased incidence of morbidity and mortality after major lung resection compared to patients who were able to exercise. Methods: Three hundred and ninety one patients submitted to pulmonary lobectomy or pneumonectomy for lung cancer were analyzed. Forty-five of these patients were unable to perform a preoperative maximal stair climbing test for underlying comorbidities. Unadjusted and propensity score case matched comparisons were performed between patients who could and who could not perform a preoperative stair climbing test. Multivariable analyses were then performed to identify predictors of morbidity and mortality, and were validated by bootstrap bagging. Results: Patients who could not perform the stair climbing test had similar morbidity rates (31.1 vs. 35.6%, respectively, PZ0.7), but higher mortality rates (15.6 vs. 4.4%, respectively, PZ0.08) and deaths among complicated patients (50 vs. 12.5%, respectively, PZ0.025), compared to propensity score matched patients who could perform the stair climbing test. Logistic regression analyses showed that the inability to perform the stair climbing test was an independent and reliable predictor of mortality (PZ0.005) but not of morbidity (PZ0.2). Conclusions: Patients unable to perform a preoperative maximal exercise test had an increased risk of mortality after major lung resection. Half of these patients did not survive postoperative complications, due to their decreased aerobic reserve caused by physical inactivity which made them unable to cope with the increased oxygen demand.

The impact of immediate breast reconstruction on the time to delivery of adjuvant therapy: the iBRA-2 study

Background: Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods: Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results: A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions: IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown

Lung surgery: identifying the subgroup at risk for sputum retention. Eur J Cardiothorac Surg

Lung surgery: identifying the subgroup at risk for sputum retention This information is current as of August 24, 2006 http://ejcts.ctsnetjournals.org/cgi/content/full/22/1/18 located on the World Wide Web at: The online version of this article, along with updated information and services, is Abstract Objectives: Sputum retention after lung surgery is a potentially lethal condition, which can progress to atelectasis, pneumonia and respiratory failure requiring ventilatory support. Previous studies have concentrated on the treatment of postoperative respiratory complications but few have studied the risk factors for sputum retention. This prospective study was designed to identify the risk factors which may lead to the development of sputum retention after lung surgery. Methods: Three hundred sixty-one patients underwent lung surgery between January 1997 and December 1999 in a specialist Thoracic Surgery Unit (pneumonectomy, lobectomy, wedge or segmental resection, bullectomy, etc). Preoperative and intraoperative data collected prospectively included potential risk factors: chronic obstructive airway disease (COAD), forced expiratory volume in 1 s ðFEV1Þ , 50%, current smokers, ischaemic heart disease (IHD), cerebrovascular disease (CVA), resection of phrenic or recurrent laryngeal nerve, or absence of regional analgesia. Univariate and multivariate analysis was performed. Results: Sputum related complications occurred in 108 patients (30%). There were 17 deaths of which nine were due to complications related to sputum retention. Univariate analysis confirmed current smokers (n ¼ 128), COAD (n ¼ 103), IHD (n ¼ 41), prior history of CVA (n ¼ 16), FEV1 , 50% (n ¼ 48), and absence of regional anaesthesia as significant risk factors (P , 0:01). The multivariate analysis confirmed current smokers, IHD and absence of regional anaesthesia as risk factors. Conclusions: A subgroup of lung surgery patients at high risk for postoperative sputum retention can be predicted by the presence of one of the following criteria: current smokers, history of COAD, CVA, or IHD, and absence of regional analgesia. Prophylactic measures should be considered in this group to reduce the incidence of sputum retention.

Successful Endobronchial stenting for bronchial compression from a massive thoracic aortic aneurysm

A case of bronchial occlusion caused by a thoracic aortic aneurysm and the relief of this obstruction by the implantation of expandable metallic stents is described. Stent deployment provided an immediate improvement in lung ventilation and chest radiograph appearances. Stent insertion was uncomplicated, but weaning from mechanical ventilation was unsuccessful and the patient died from a ventilator-associated pneumonia, unrelated to the procedure. Endobronchial stenting should be considered as a non-invasive therapy for the treatment of bronchial obstruction, with respiratory compromise, caused by a thoracic aortic aneurysm when vascular surgery is not an option. The medium to long term survival of this patient group is poor. This can be attributed to complications related to the stent and also to the poor performance status of these patients
