Bronchial rupture by blunt chest trauma is rare. We present a case of bronchial injury after blunt chest trauma that was repaired surgically by primary reconstruction. We performed a review of literature to verify if primary reconstruction is suitable for the treatment of adult patients with blunt bronchial injury. A systematic search was conducted to identify cohort studies of bronchial rupture after blunt chest trauma in adult patients between 1985 and 2016 (n=215 articles). Studies were included concerning four or more patients and in case patient data could be extracted. This resulted in 19 articles for final review, consisting of 155 patients. Mean age of 155 patients was 28 (range, 18-60) years. The main bronchus was mostly injured (81%), in 5% including an injury of the trachea and in 14% lobar bronchi injury. Surgical repair was performed in 95% of patients: primary anastomosis in 72%, pneumonectomy in 15%, lobectomy or sleeve resection in 12% and other in 1%. Perioperative mortality rate was 10%. Other complications occurred in 17% (empyema, rebleeding, stenosis and fistula, among others). Data concerning the occurrence of longterm complications or long-term follow-up was not found. Statistical evaluation could not be performed due to lack of consistent patient data. No strong recommendations regarding type and timing of surgery can be made based on the available literature. Based on our multidisciplinary opinion we would advocate primary anastomosis in case of stable vital signs with the goal to preserve healthy lung parenchyma. Moreover, it may be considered transferring these rare cases to an experienced thoracic and trauma surgery center.

Laparotomy for trauma has a high complication rate resulting in significant morbidity and mortality. Most events occur in the early postoperative period. Further prospective research needs to be conducted in order to identify possibilities to improve care in the future.

FDG-PET/CT has an advantage over CT as a predictive tool to identify histopathologic response after 3 weeks of EGFR-TKI treatment in NSCLC patients.

Over recent years, [18F]-fluorodeoxyglucose positron emission tomography acquired together with low dose computed tomography (FDG-PET/CT) has proven its role as a staging modality in patients with non-small cell lung cancer (NSCLC). The purpose of this review was to present the evidence to use FDG-PET/CT for response evaluation in patients with NSCLC, treated with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI). All published articles from 1 November 2003 to 1 November 2013 reporting on 18F-FDG-PET response evaluation during EGFR-TKI treatment in patients with NSCLC were collected. In total 7 studies, including data of 210 patients were eligible for analyses. Our report shows that FDG-PET/CT response during EGFR-TKI therapy has potential in targeted treatment for NSCLC. FDG-PET/CT response is associated with clinical and radiologic response and with survival. Furthermore FDG-PET/CT response monitoring can be performed as early as 1-2 wk after initiation of EGFR-TKI treatment. Patients with substantial decrease of metabolic activity during EGFR-TKI treatment will probably benefit from continued treatment. If metabolic response does not occur within the first weeks of EGFR-TKI treatment, patients may be spared (further) unnecessary toxicity of ineffective treatment. Refining FDG-PET response criteria may help the clinician to decide on continuation or discontinuation of targeted treatment.

The purpose of this study was to prospectively evaluate the timing of metabolic response monitoring with 18 F-FDG PET of (neoadjuvant) erlotinib treatment in patients with early-stage non-small cell lung cancer. Methods: This study was designed as an open-label phase II trial performed in 4 hospitals in The Netherlands. Patients received preoperative erlotinib (150 mg) once daily for 3 wk. Response evaluation was performed after 4-7 d and at 3 wk with 18 F-FDG PET/CT scans. Tumor 18 F-FDG uptake and changes were measured as standardized uptake values (SUVs). The metabolic response was classified on the basis of European Organization for Research and Treatment of Cancer criteria (.25% decrease in the maximum SUV) and was compared with histopathologic regression as observed in the resection specimen. Results: From December 2006 to November 2010, 60 patients with non-small cell lung cancer eligible for surgical resection were enrolled in this study. For 43 patients (18 men and 25 women), baseline 18 F-FDG PET/CT scans as well as both monitoring scans and histopathologic response monitoring were available. A partial metabolic response on 18 F-FDG PET/CT scans was observed for 10 patients (23%) after 1 wk and for 14 patients (33%) after 3 wk. Histopathologic examination revealed regression (necrosis of .50%) in 11 patients (26%). In these patients, the maximum SUV decreased by a mean of 17% within 1 wk and a mean of 31% at 3 wk. Seven patients were identified as responders within 1 wk. Conclusion: Response monitoring with 18 F-FDG PET/CT within 1 wk after the start of erlotinib treatment identified approximately 64% of histopathologic responders on the basis of European Organization for Research and Treatment of Cancer criteria.

Pre-operative FDG tumor uptake in patients with NSCLC is predictive for survival after complete surgical resection. GC-SUVmax, as an additional value to SUVmax, may better approach competitive inhibition of FDG and glucose in tumors, however, in this study this potential advantage, if any, was very small.

Response monitoring using fluorodeoxyglucose positron emission tomography acquired together with low dose computed tomography (FDG-PET/CT) textural features has potential in targeted treatment with erlotinib in non-small cell lung cancer (NSCLC) patients. Patients with substantial decrease of metabolic activity during erlotinib treatment will probably benefit from continued treatment. However, various aspects of the method (quantification tools, cut-off values, etc.) need to be standardized before the software becomes widely available in a similar manner as standardized uptake value (SUV) measurements. Heterogeneity on FDG-PET/CT opened an additional window for innovation but simultaneously a new challenge for molecular hybrid imaging.
