PURPOSE: Despite the recent CREST trial demonstrating a survival benefit to thoracic radiotherapy (TRT) for patients with extensive-stage small-cell lung cancer (ES-SCLC) with response to chemotherapy, as well as endorsement by current National Comprehensive Cancer Network guidelines, TRT may not be uniformly delivered in clinical practice across all circumstances. METHODS AND MATERIALS: We surveyed US academic thoracic radiation oncologists regarding their practice patterns for TRT and assessed conditions in which withholding TRT could be warranted...

OBJECTIVES: Postoperative atrial fibrillation (POAF) occurs frequently in patients after noncardiac thoracic surgery and has been associated with increased morbidity and risk of stroke. Recent studies have shown conflicting results on the role of neutrophil-lymphocyte ratio (NLR) and its association with the development of POAF after cardiac surgery. Our goal was to determine whether an association exists between NLR and the incidence of POAF after non-cardiac thoracic surgery. METHODS: Using a database of 259 consecutive patients age 60 or older who had anatomic lung resection or oesophagectomy for oncologic resection, we compared preoperative, postanaesthesia care unit and postoperative day 1 NLR between patients who did and did not develop POAF during their hospitalization using Fisher's exact test or logistic regression...

: CT ventilation imaging is an exciting functional imaging modality that combines four-dimensional computed tomography (4DCT) and deformable image registration (DIR) to provide exquisite ventilation maps of the lung. CT ventilation imaging can be used for: (1) Functional avoidance in thoracic radiation therapy, (2) Imaging longitudinal changes in regional lung function for treatment assessment and adaptation, (3) Image-assisted diagnosis of non-oncologic respiratory diseases. CT ventilation imaging uses CT, a predominantly anatomic imaging modality, and through imaging processing creates functional images...

PURPOSE: The current standard-of-care imaging used to evaluate lung cancer patients for surgical resection is nuclear-medicine ventilation. Surgeons use nuclear-medicine images along with pulmonary function tests (PFT) to calculate percent predicted postoperative (%PPO) PFT values by estimating the amount of functioning lung that would be lost with surgery. 4DCT-ventilation is an emerging imaging modality developed in radiation oncology that uses 4DCT data to calculate lung ventilation maps...

PURPOSE: To propose a method of real time tracking of respiratory motion in patients undergoing radiation therapy. Radar technology can be employed to detection the movement of diaphragm and thoracic anatomy. METHODS: A radar transceiver was specially designed. During experiment, the radar device was securely attached to a fixed frame. Respiratory motion was simulated with: 1) Varian RPM phantom, 2) Standard Imaging Respiratory Gating Platform. Signals recorded with radar equipment were compared with those measured with Varian RPM system as a reference...

AIM: The aim of this study was to assess the concordance of PET measurements of F-FDG uptake in tumor and normal tissues obtained on Australia's first clinical PET/MRI scanner in comparison to PET/CT, with comparison against published data. METHODS: One hundred subjects were prospectively recruited from an unselected, heterogeneous group of cancer patients to undergo F-FDG PET/CT and PET/MRI on the same day. SUVs of physiological regions and tumor tissues obtained by PET/MRI and PET/CT were compared and benchmarked against existing published data...

The EML4-ALK pathway plays an important role in a significant subset of non-small cell lung cancer patients. Treatment options such as ALK tyrosine kinase inhibitors lead to improved progression free survival and overall survival. These therapeutic options are chosen on the basis of the identification of the underlying genetic signature of the EML-ALK translocation. Efficient and easily accessible testing tools are required to identify eligible patients in a timely fashion. While FISH techniques are commonly used to detect this translocation, the broad implementation of this type of ALK testing into routine diagnostics is not optimal due to technical, structural and financial reasons...

INTRODUCTION: Docetaxel and erlotinib are registered second-line treatments for wild-type EGFR NSCLC. Previous studies suggested a predictive value of the Veristrat test in second-line therapy of NSCLC, classifying patients as either Veristrat "good" or "poor". EMPHASIS-lung aimed at exploring this predictive effect in patients with squamous cell NSCLC. The trial closed prematurely due to low accrual and results from other trials. Our analysis includes an exploratory combined analysis with results from the PROSE trial...

INTRODUCTION: Oncoplastic breast conservation surgery (OBCS) combines the principles of surgical oncology and plastic surgery. OBCS has now become a growing option for the treatment of breast cancer and forms a part of breast-conserving therapy (BCT). We sought to investigate and report our experience in two breast units in Glasgow (Victoria Infirmary and Western Infirmary) on volume replacement OBCS. MATERIALS AND METHODS: Details of patients treated with volume replacement OBCS were identified from a prospectively recorded database from November 2010 to October 2015...

BACKGROUND: Dorsal intercostal artery perforator (DICAP) flap is an ideal flap to be used for posterior trunk defects since it leads to lower donor-site morbidity and shorter operative times, offers easy surgical planning, and uses a reliable and easily identifiable artery. MATERIALS AND METHODS: The study retrospectively reviewed 52 patients with meningomyelocele defects that were closed with DICAP flap between January 2007 and May 2015. SURGICAL TECHNIQUE: Each of the 4th to 12th posterior intercostal arteries can be used as dorsal perforators...

BACKGROUND: The high recurrence rate following keloid resection has generated interest in adjuvant treatments for this disease. OBJECTIVE: This study assesses keloid recurrence when treated with surgery and adjuvant radiotherapy. METHODS: Retrospective analysis of resected keloids in patients referred to a Chilean radiation oncology centre between 2006 and 2013. Local recurrence was defined as new tissue growth on the surgical scar margin...

OBJECTIVE: Esophageal resection is a traumatic intervention usually performed on patients with poor condition, resulting high mortality and morbidity. To improve the high incidence of complications, minimal invasive interventions were introduced. The results of the thoracoscopically and laparoscopically performed esophageal resection (McKeown) was investigated after 20 cases and the technical details of the surgical intervention are presented. PATIENTS AND METHOD: 20 thoracoscopic esophageal resection with laparoscopic gastric tube formation (sec...

BACKGROUND: Various factors may influence outcomes after lobectomy for lung cancer. Postgraduate subspecialty training in general thoracic surgery with a focus on minimally invasive surgery (MIS) and thoracic oncology was completed by an established cardiothoracic surgeon on the hospital staff in July 2007, and principles emphasized in that training were incorporated into practice through formation of a subspecialty program. We hypothesized that establishing a dedicated general thoracic surgeon-lead subspecialty program, with focus on MIS and thoracic oncology, would improve short-term and long-term outcomes...
