Differential diagnosis by the FDG PET/CT between recurrence of primary lung cancer and the postoperative change is difficult. The results of our study, favorable diagnostic accuracy as higher 70% were obtained by setting the optimal cutoff value of SUVmax except for pleural lesions. Diagnostic performance was further improved by adding delayed image. The usefulness of FDG PET/CT was confirmed in diagnosing recurrence of NSCLC after surgery.

© 2014 Al-Kandari et al.; licensee BioMed Central Ltd. Introduction: Ganglioneuroma is a rare tumor in the posterior mediastinum; fat-containing ganglioneuromas are rarely reported. The present case report documents a brown fat-containing, posterior mediastinal ganglioneuroma, which has not been reported previously. Radiological examination, in particular 18F-2-fluoro-2-deoxyglucose-positron emission tomography, suggested that the tumor had low-grade malignant potential. This led to uncertainty at preoperative diagnosis. Case presentation: An asymptomatic 66-year-old Japanese woman with no significant past medical history was referred for the evaluation of a posterior mediastinal mass. Although its size had not changed in the past 5 years, a malignant lipomatous tumor could not be excluded due to the presence of intratumoral fat and increased 18F-2-fluoro-2-deoxyglucose uptake observed by positron emission tomography imaging. A computed tomography-guided core-needle biopsy revealed a mixture of mature adipocytes, spindle-shaped cells, and fibrotic stroma. Definite diagnosis was not possible, and surgical resection was performed. Three years after the surgery, she remains disease-free. Conclusions: Histological diagnosis of the surgically resected mass confirmed ganglioneuroma with substantial amounts of white and brown adipose tissues in peripheral areas. The existence of both ganglion cells and brown fat tissue intensified the accumulation of 18F-2-fluoro-2-deoxyglucose, resulting in a false-positive result by positron emission tomography. Considering this, ganglioneuroma should not be excluded either clinically or pathologically in fat-containing, posterior mediastinal tumors.

Background: Epidermal growth factor receptor (EGFR) mutations play a vital role in the prognosis of patients with lung adenocarcinoma. Such somatic mutations are more common in women who are non-smokers with adenocarcinoma and are of Asian origin. However, to our knowledge, there are few studies that have focused on men. Materials and Methods: One hundred and eighty-four consecutive patients (90 men and 94 women) of resected lung adenocarcinoma were studied retrospectively. Results: EGFR mutations were positive in 48.9% and negative (wild type) in 51.1%. Overall mutation was significant in women (66.0% vs. 32.2%) compared with men (p < 0.001). For overall patients, EGFR mutation status was associated with gender, pStage, pT status, lepidic dominant histologic subtype, pure or mixed ground-glass nodule type on computed tomography and smoking status. However, in men, EGFR mutation status was only associated with lepidic dominant histologic subtype and not the other variables. Interestingly, the Brinkman index of men with mutant EGFR also did not differ from that for the wild type (680.0±619.3 vs. 813.1±552.1 p=0.1077). Conclusions: The clinical characteristics of men with lung adenocarcinoma related to EGFR mutation are not always similar to that of overall patients. Especially we failed to find the relationship between EGFR mutations and smoking status in men.

A neurogenic tumor in the cervico-thoracic region is rare. To remove such a tumor, a supraclavicular approach, mini-sternotomy, video-assisted thoracic surgery, or a combination of these procedures is performed in consideration of minimally invasive surgery. A 25-year-old male was pointed out by others as showing a left cervical swelling 6 months previously. He was diagnosed with a cervico-thoracic tumor of 5.5×4.5 cm by chest computed-tomographic scanning, originating from the vagus nerve and passing to the level of the aortic arch. Physical examination showed café-au-lait macules, Lisch nodules, and scoliosis, and the patient was diagnosed with neurofibromatosis type 1 (NF-1). We incised the skin from the left cervical region to median anterior thorax. A figure-L unilateral mini-sternotomy at the left first intercostal space was performed. The tumor originating from the vagus nerve was resected by 22 cm in its longitudinal length, and pathological examination showed neurofibroma. A type I thyroplasty for hoarseness from the left recurrent nerve palsy was performed. A combination of the figure-L unilateral mini-sternotomy and supraclavicular approach is considered an effective and useful minimally invasive approach for a cervico-thoracic tumor.

Some previous studies reported the relationship between the mutation status of epidermal growth factor receptor (EGFR) gene and serum carcinoembryonic antigen (CEA) level in advanced or recurrent lung adenocarcinomas. In the present study, this relationship was examined in resected lung adenocarcinomas. One hundred thirty five resected lung adenocarcinoma patients were reviewed retrospectively. Mutations of the EGFR gene were detected in 64 of the 135 patients, the most common being deletions in exon 19 and the L858R mutations in exon 21. The patients with normal serum CEA level had favorable prognosis, whereas those with high had poor prognosis. The 5-year survival of the patients with EGFR mutation-negative was significantly worse than that of the patients with EGFR mutation-positive. Both univariate and multivariate analyses indicated an independent prognostic impact of the combined use of serum CEA level and the status of EGFR mutation. There was no difference in the rate of EGFR gene mutations according to the serum CEA level. Furthermore we also failed to find the differences in the serum CEA level based on the EGFR mutation status. The rate of deletions in exon 19 and/or the L858R mutation in exon 21 was not also related to the serum CEA level. In conclusions we failed to find the relationship between the serum CEA level and the EGFR mutation status in resected lung adenocarcinomas. © 2013, The Japanese Society of Strategies for Cancer Research and Therapy.

Aims: The relationship between the maximum standardized uptake values (SUVmax) on positron emission tomography (PET) and serum carcinoembryonic antigen (CEA) level in non-small cell lung cancer (NSCLC) patients was investigated. Methods: Consecutively, 197 surgically resected NSCLC patients with preoperative staging including serum CEA and PET were reviewed retrospectively. Results: When patients were subdivided into two groups based on the median value of the SUVmax (6.6), the 5-year survival of patients with a high SUVmax was 63.20%, which was significantly worse than patients with a low SUVmax (87.29%, P=0.0004). The 5-year survival of patients with normal and high serum CEA level was 82.70 and 51.08%, respectively (P<0.0001). Univariate and multivariate analyses indicated the independent prognostic impact of the SUVmax and serum CEA level. Patients with both low SUVmax and normal serum CEA level had favorable prognosis, whereas those with both high SUVmax and high serum CEA level had poor prognosis. Conclusion: Preoperative SUVmax and serum CEA level are independent prognostic factors for survival in NSCLC. The combined use of preoperative SUVmax and serum CEA level might be a better prognostic indicator. © 2012 Wiley Publishing Asia Pty Ltd.

Background: Previous studies showed the prognostic impact of inflammatory markers such as the neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP), in resected non-small cell lung cancer (NSCLC). However, there are no studies that examined both of these markers simultaneously. Patients and Methods: Three hundred and one consecutive cases of resected NSCLC with a follow-up period of more than 5 years were reviewed retrospectively. Results: A significant association was only observed between NLR and patients ' survival (p<0.0001). High CRP also led to a higher 5-year survival rate than low CRP (38.71% vs. 70.71%, p<0.0001). We evaluated the prognostic significance of the use of NLR and CRP combined. The 5-year survival of patients with both low NLR and low CRP was 74.18%. On the other hand, that of patients with both of these at a low level was significantly poor (20.00%, p<0.0001). Univariate and multivariate analyses of the clinicopathological factors affecting survival revealed that the combined use of preoperative NLR and CRP was an independent prognostic determinant. Conclusion: The combined use of preoperative NLR and CRP might be useful to predict the prognosis of patients with NSCLC.
