Sun Y, Sun Y, Li Z, Song S, Wu K, Mao J, Cheng J. 18F-FAPI PET/CT performs better in evaluating mediastinal and hilar lymph nodes in patients with lung cancer: comparison with 18F-FDG PET/CT. Eur J Med Res 2024; 29:9. [PMID: 38173034 PMCID: PMC10763273 DOI: 10.1186/s40001-023-01494-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 11/01/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of fluorine 18 (18F) labeled fibroblast activation protein inhibitor (FAPI) in identifying mediastinal and hilar lymph node metastases and to develop a model to quantitatively and repeatedly identify lymph node status. METHODS Twenty-seven patients with 137 lymph nodes were identified by two PET/CT images. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of lymph node status were analyzed, and the optimal cut-off value was identified by ROC analysis. RESULTS The SUVmax of metastatic lymph nodes on 18F-FAPI was higher than that on 18F-FDG PET/CT (10.87 ± 7.29 vs 6.08 ± 5.37, p < 0.001). 18F-FAPI presented much greater lymph node detection sensitivity, specificity, accuracy, PPV and NPV than 18F-FDG PET/CT (84% vs. 71%; 92% vs. 67%; 90% vs. 69%, 84% vs. 52%, and 92% vs. 83%, respectively). Additionally, the diagnostic effectiveness of 18F-FAPI in small lymph nodes was greater than that of 18F-FDG PET/CT (specificity: 96% vs. 72%; accuracy: 93% vs. 73%; PPV: 77% vs. 33%, respectively). Notably, the optimal cut-off value for specificity and PPV of 18F-FAPI SUVmax was 5.3; the optimal cut-off value for sensitivity and NPV was 2.5. CONCLUSION 18F-FAPI showed promising diagnostic efficacy in metastatic mediastinal and hilar lymph nodes from lung cancer patients, with a higher SUVmax, especially in small metastatic nodes, compared with 18F-FDG. In addition, this exploratory work recommended optimal SUVmax cutoff values to distinguish between nonmetastatic and metastatic lymph nodes, thereby advancing the development of image-guided radiation. Trial registration ClinicalTrials.gov identifier: ChiCTR2000036091.

Abstract
Metastatic bone disease is a common and devastating complication to cancer, confounding treatments and recovery efforts and presenting a significant barrier to de-escalating the adverse outcomes associated with disease progression. Despite significant advances in the field, bone metastases remain presently incurable and contribute heavily to cancer-associated morbidity and mortality. Mechanisms associated with metastatic bone disease perpetuation and paralleled disruption of bone remodeling are highlighted to convey how they provide the foundation for therapeutic targets to stem disease escalation. The focus of this review aims to describe the preclinical modeling and diagnostic evaluation of metastatic bone disease as well as discuss the range of therapeutic modalities used clinically and how they may impact skeletal tissue.

Abstract
BACKGROUND Among patients diagnosed with stage IA non-small cell lung cancer (NSCLC), the incidence of occult brain metastasis is low, and several professional societies recommend against brain imaging for staging purposes. The goal of this study was to characterize the use of brain imaging among Medicare patients diagnosed with stage IA NSCLC. METHODS Using data from linked SEER-Medicare claims, we identified patients diagnosed with AJCC 8th edition stage IA NSCLC in 2004 through 2013. Patients were classified as having received brain imaging if they underwent head CT or brain MRI from 1 month before to 3 months after diagnosis. We identified factors associated with receipt of brain imaging using multivariable logistic regression. RESULTS Among 13,809 patients with stage IA NSCLC, 3,417 (25%) underwent brain imaging at time of diagnosis. The rate of brain imaging increased over time, from 23.5% in 2004 to 28.7% in 2013 (P=.0006). There was significant variation in the use of brain imaging across hospital service areas, with rates ranging from 0% to 64.0%. Factors associated with a greater likelihood of brain imaging included older age (odds ratios [ORs] of 1.16 for 70-74 years, 1.13 for 75-79 years, 1.31 for 80-84 years, and 1.46 for ≥85 years compared with 65-69 years; all P<.05), female sex (OR, 1.09; P<.05), black race (OR 1.23; P<.05), larger tumor size (ORs of 1.23 for 11-20 mm and 1.28 for 21-30 mm tumors vs 1-10 mm tumors; all P<.05), and higher modified Charlson-Deyo comorbidity score (OR, 1.28 for score >1 vs score of 0; P<.05). CONCLUSIONS Roughly 1 in 4 patients with stage IA NSCLC received brain imaging at the time of diagnosis despite national recommendations against the practice. Although several patient factors are associated with receipt of brain imaging, there is significant geographic variation across the United States. Closer adherence to clinical guidelines is likely to result in more cost-effective care.

Computed Tomography Radiomics for Residual Positron Emission Tomography-Computed Tomography Uptake in Lymph Nodes after Treatment. Cancers (Basel) 2020; 12:cancers12123564. [PMID: 33260608 PMCID: PMC7761511 DOI: 10.3390/cancers12123564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 11/17/2020] [Accepted: 11/26/2020] [Indexed: 11/16/2022] Open
Abstract
Simple Summary In this study we explored the predictive ability of radiomics in non-small cell lung cancer patients, and reported the complementary role of radiomics in predicting the treatment response of the lymph nodes. Radiomics analysis is a cutting-edge technology for the noninvasive assessment of tumor biology, which converts medical images into mineable high-dimensional data. Our method is cost-effective with no need for additional studies, and moreover, we used an easily reproducible study method that can be applicable in further studies using radiomics in oncology. Abstract Although a substantial decrease in 2-[fluorine-18]fluoro-2-deoxy-d-glucose (FDG) uptake on positron emission tomography-computed tomography (PET-CT) indicates a promising metabolic response to treatment, predicting the pathologic status of lymph nodes (LN) remains challenging. We investigated the potential of a CT radiomics approach to predict the pathologic complete response of LNs showing residual uptake after neoadjuvant concurrent chemoradiotherapy (NeoCCRT) in patients with non-small cell lung cancer (NSCLC). Two hundred and thirty-seven patients who underwent NeoCCRT for stage IIIa NSCLC were included. Two hundred fifty-two CT radiomics features were extracted from LNs showing remaining positive FDG uptake upon restaging PET-CT. A multivariable logistic regression analysis of radiomics features and clinicopathologic characteristics was used to develop a prediction model. Of the 237 patients, 135 patients (185 nodes) met our inclusion criteria. Eighty-seven LNs were proven to be malignant (47.0%, 87/185). Upon multivariable analysis, metastatic LNs were significantly prevalent in females and patients with adenocarcinoma (odds ratio (OR) = 2.02, 95% confidence interval (CI) = 0.88–4.62 and OR = 0.39, 95% CI = 0.19–0.77 each). Metastatic LNs also had a larger maximal 3D diameter and higher cluster tendency (OR = 9.92, 95% CI = 3.15–31.17 and OR = 2.36, 95% CI = 1.22–4.55 each). The predictive model for metastasis showed a discrimination performance with an area under the receiver operating characteristic curve of 0.728 (95% CI = 0.654–0.801, p value < 0.001). The radiomics approach allows for the noninvasive detection of metastases in LNs with residual FDG uptake after the treatment of NSCLC patients.

Abstract
Clinical studies of predictive diagnostic tests consider the evaluation of a single test and comparison of two tests regarding their predictive accuracy of disease status. The positive predictive value (PPV) curve is used for assessing the probability of predicting the disease given a positive test result. The sequential property of one PPV curve had been studied. However, in later stages of diagnostic test development, it is more interesting to compare predictive accuracy of two tests. In this article, we propose a group sequential test for the comparison of PPV curves for paired designs when both diagnostic tests are applied to the same subject. We first derive asymptotic properties of the sequential differences of two correlated empirical PPV curves under the common case-control sampling. We then apply these results to develop a group sequential test procedure. The asymptotic results are also critical for deriving both the optimal sample size ratio and minimal required sample sizes for the proposed procedure. Our simulation studies show that the proposed sequential testing maintains the nominal type I error rate in finite samples. The proposed design is illustrated in a hypothetical lung cancer predictive trial and in a cancer diagnostic trial.

Abstract
BACKGROUND Lung cancers or (Bronchogenic-Carcinomas) are the disease in certain parts of the lungs in which irresistible multiplication of abnormal cells leads to the inception of a tumor. Lung cancers consisting of two substantial forms based on the microscopic appearance of tumor cells are: Non-Small-Cell-Lung-Cancer (NSCLC) (80 to 85%) and Small-Cell-Lung-Cancer (SCLC) (15 to 20%). DISCUSSION Lung cancers are existing luxuriantly across the globe and the most prominent cause of death in advanced countries (USA & UK). There are many causes of lung cancers in which the utmost imperative aspect is the cigarette smoking. During the early stage, there is no perspicuous sign/symptoms but later many symptoms emerge in the infected individual such as insomnia, headache, pain, loss of appetite, fatigue, coughing etc. Lung cancers can be diagnosed in many ways, such as history, physical examination, chest X-rays and biopsy. However, after the diagnosis and confirmation of lung carcinoma, various treatment approaches are existing for curing of cancer in different stages such as surgery, radiation therapy, chemotherapy, and immune therapy. Currently, novel techniques merged that revealed advancements in detection and curing of lung cancer in which mainly includes: microarray analysis, gene expression profiling. CONCLUSION Consequently, the purpose of the current analysis is to specify and epitomize the novel literature pertaining to the development of cancerous cells in different parts of the lung, various preeminent approaches of prevention, efficient diagnostic procedure, and treatments along with novel technologies for inhibition of cancerous cell growth in advance stages.

Abstract
Background/Objectives: Evaluation of mediastinal lymphadenopathy (MLA) is a great diagnostic challenge considering the myriad of causes. In recent years, the role of endoscopic ultrasound (EUS) has been greatly extended in evaluation of MLA due to its safety, reliability, and accuracy. The present study details the role of EUS-guided-fine-needle aspiration/fine-needle biopsy (EUS-FNA/FNB) in MLA of unknown origin. Methods: Seventy-two patients (34 men) with MLA of unknown etiology were studied. Mediastinum was evaluated with linear echoendoscope and FNA/FNB was performed with 22-G needle and sent for cytology, histopathological, and mycobacterial growth indicator tube/GeneXpert evaluation. EUS-FNA/FNB diagnosis was based on cytology reporting by pathologists. Patients tolerated the procedure, and insertion of needle into the lesion was always successful without any complications. Results: EUS-FNA/FNB established a tissue diagnosis in 66/72 patients in first sitting, while six patients underwent repeat procedure. EUS-FNA diagnoses (after second sitting) were tuberculous lymphadenitis in 45/72 (62.5%), metastatic lymph nodes 12/72 (16.7%), reactive lymphadenopathy 6/72 (8.3%), sarcoidosis 4/72 (5.6%), and lymphoma 2/72 (2.8%), while it was nondiagnostic in 3/72 (4.1%) patients. Final diagnosis was based on combined clinical presentation, EUS-FNA/FNB result and clinicoradiological response to treatment on long-term follow-up of 6 months. Conclusion: EUS echo features along with EUS-FNA/FNB can diagnose MLA and surgical biopsy can be avoided.

Abstract
Background and Objective: The role of EUS-FNA biopsy (EUS-FNAB) for detection of metastatic lesions (mets) to adrenals has not been evaluated systematically. Our aim is to systematically evaluate the performance characteristics of EUS-FNAB in detecting metastasis to the adrenal glands. Materials and Methods: We performed a systematic search on PubMed and OvidSP from January 1990 to July 2016 using various search terms for EUS and adrenal lesion. Only articles published in English literature were included in the study. Studies with fewer than 10 patients were excluded from the study. Publication bias was assessed using Begg-Mazumdar test and visual inspection of funnel plots. Results: Eight studies including 360 adrenal lesions that underwent EUS-FNAB were identified. Of these, 137 FNABs were conclusive for malignancy. Sensitivity of EUS-FNAB in detecting metastasis to the adrenals was 95% (95% confidence interval [CI]: 90%–98%) and specificity was 99% (95% CI: 96%–100%). Pooled positivity of EUS-FNAB in detecting lung cancer metastasis to the adrenals was 44% (95% CI: 31.5%–57.3%). No evidence of publication bias was noted. Conclusion: Our study demonstrates that EUS-FNAB is highly sensitive and specific in detecting metastasis to adrenals. It also shows that up to about half of the patients with lung cancer and adrenal lesions on imaging have metastasis, a finding with profound implications on lung cancer staging and treatment.

Abstract
SummaryFDG-PET/CT is increasingly used in staging of lung cancer as single „one stop shop” method. Aim, patients, methods: We prospectively included 104 neurological asymptomatic patients (65 years, 26% women) with primary diagnosis of lung cancer. In all patients PET/CT including cerebral imaging and cerebral MRI were performed. Results: Diagnosis of brain metastases (BM) was made by PET/CT in 8 patients only (7.7%), by MRI in 22 (21.2%). In 80 patients both PET/CT and MRI showed no BM. In 6 patients (5.8%) BM were detectable on PET/CT as well as on MRI. Exclusive diagnosis of BM by MRI with negative finding on PET/CT was present in 16 patients (15.4%). 2 patients (1.9%) had findings typical for BM on PET/CT but were negative on MRI. With MRI overall 100 BM were detected, with PET/CT only 17 BM (p < 0.01). For the diagnosis of BM PET/CT showed a sensitivity of 27.3%, specificity of 97.6%, positive predictive value of 75% and negative predictive value of 83.3%. BM diameter on PET/CT and MRI were consistent in 43%, in 57% BM were measured larger on MRI. Discussion: Compared to the gold standard of MRI for cerebral staging a considerable number of patients are falsely diagnosed as free from BM by PET/CT. MRI is more accurate than PET/CT for detecting multiple and smaller BM. Conclusion: In patients with a curative option MRI should be performed additionally to PET/CT for definitive exclusion of brain metastases.

Abstract
Vertebral metastasis of non-small-cell lung cancer (NSCLC) often leads to neurological paralysis, with deterioration of the patients' activities of daily living (ADL). Surgical treatments for the symptoms are unlikely to be recommended due to the poor prognosis of patients with advanced NSCLC. The aim of the present study was to retrospectively evaluate the clinical outcome of posterior spinal fixation surgery in patients with neurological paralysis resulting from vertebral metastasis of NSCLC. Between April, 2007 and March, 2012, 4 patients (3 men and 1 woman; median age, 56.5 years) underwent fixation surgery at the Shiga University of Medical Science Hospital (Otsu, Japan). The mean preoperative Tokuhashi and Tomita scores of the patients were high (8.25 and 7.0, respectively). However, the Frankel grade functional score and performance status of the patients improved following fixation surgery, after which all patients received chemoradiotherapy. Postoperatively, the median paralysis-free time was 41 months (range, 17-42 months) and the median survival time was 42.5 months (range, 22-43 months). According to the functional scores, the patients had a poor prognosis, which may have been a contraindication for fixation surgery. In these cases, however, surgical treatment improved the patients' ADL and increased the likelihood of receiving anticancer therapy, contributing to the prolongation of survival. Therefore, fixation surgery may be beneficial for patients with neurological paralysis following vertebral metastasis of advanced NSCLC.

Abstract
The article proposes a unified least squares method to estimate the receiver operating characteristic (ROC) parameters for continuous and ordinal diagnostic tests, such as cancer biomarkers. The method is based on a linear model framework using the empirically estimated sensitivities and specificities as input "data." It gives consistent estimates for regression and accuracy parameters when the underlying continuous test results are normally distributed after some monotonic transformation. The key difference between the proposed method and the method of Tang and Zhou lies in the response variable. The response variable in the latter is transformed empirical ROC curves at different thresholds. It takes on many values for continuous test results, but few values for ordinal test results. The limited number of values for the response variable makes it impractical for ordinal data. However, the response variable in the proposed method takes on many more distinct values so that the method yields valid estimates for ordinal data. Extensive simulation studies are conducted to investigate and compare the finite sample performance of the proposed method with an existing method, and the method is then used to analyze 2 real cancer diagnostic example as an illustration.

Abstract
Further elucidation of the molecular mechanisms underlying lung cancer (LC) is essential for the development of new effective therapeutic agents. Recently, involvement of Wnt antagonists in oncogenesis has been demonstrated in several cancers. The investigation of their contribution to lung carcinogenesis is still under investigation. We aimed to investigate whether there is a susceptibility or preventive effect of Wnt antagonist gene polymorphisms on the development and/or prognosis of LC. We investigated 110 LC patients and 160 controls. Single-nucleotide polymorphisms of Wnt antagonist genes including DKK2 (rs17037102), DKK3 (rs3206824), DKK3 intron4 G/C (rs7396187), DKK4 (rs2073664), and sFRP4 (rs1802074) were analyzed using nested polymerase chain reaction and restriction fragment length polymorphism. Results showed that patients with DKK3 AA compared with controls have a decreased risk of LC (adjusted for smoking habit, body mass index, and familial history) (P = 0.02; odds ratio [OR],0.08; 95% confidence interval [95% CI], 0.01-0.7). It was found that, for sFRP4 polymorphism, patients with GG and GA genotypes versus AA genotype controls showed a decreased risk for LC (P = 0.01; [OR, 0.19; 95% CI, 0.05-0.73 for GG genotype]; [OR = 0.18, 95% CI, 0.04-0.72 for GA genotype]). In addition, a decreased risk of LC was also found for the genotype combination of DKK3 (rs3206824) GG and sFRP4 AG + GG (P = 0.004; OR, 0.12; 95% CI, 0.02-0.58). We suggest that these 2 polymorphisms have a protective effect on LC in this study.

Abstract
RATIONALE Chronic obstructive pulmonary disease is associated with a worse overall survival in non-small cell lung cancer. Lung emphysema is one component of chronic obstructive pulmonary disease. We hypothesized that emphysema of the tumor region may result in larger tumors and a poorer overall survival. METHODS We evaluated 304 cases of non-small cell lung cancer from a prospectively enrolled cohort. The lung was divided into equal volumetric thirds (upper, middle, or lower region). Emphysema was defined as percentage of low-attenuation areas less than -950 Hounsfield units (%LAA-950) and measured for each region. Whole-lung %LAA-950 was defined as the emphysema score of the entire lung parenchyma, whereas regional %LAA-950 was the score within that particular region (upper, middle, or lower). The emphysema score of the region in which the tumor occurred was defined as the tumor %LAA-950. Tumor diameter was measured while blinded to characteristics of the lung parenchyma. A proportional hazards model was used to control for multiple factors associated with survival. MEASUREMENTS AND MAIN RESULTS Increasing tumor %LAA-950 was associated with larger tumors (P = 0.024). Survival, stratified by stage, was significantly worse in those with tumor %LAA-950 greater than or equal to the 50th percentile versus less than the 50th percentile (P = 0.046). Whole-lung %LAA-950 and regional %LAA-950 (e.g., regional emphysema without tumor occurring in the region) were not significantly associated with survival. There were no differences in presenting symptoms or locations of mediastinal or distant metastasis by emphysema score. Increasing tumor %LAA-950 was associated with an increased risk of death (adjusted hazard ratio, 1.36; confidence interval, 1.09-1.68; P = 0.006) after adjustment for age, sex, smoking status, histology, stage, performance status, chemotherapy, radiation, and surgery. Sensitivity analyses revealed no significant difference in the effect size or test of significance for each of the following conditions: (1) exclusion of cases with central tumor location, (2) exclusion of cases where surgery was performed, (3) exclusion of cases where radiation therapy was performed, (4) exclusion of cases where epidermal growth factor receptor tyrosine kinase inhibitors were administered, and (5) inclusion of only stage IV disease. CONCLUSIONS Increasing emphysema of the region in which a non-small cell lung cancer tumor occurs is associated with increasing tumor size and worse overall survival.

Time courses and value of circulating microparticles in patients with operable stage non-small cell lung cancer undergoing surgical intervention. Tumour Biol 2016; 37:11873-11882.

Abstract
Microparticles (MPs) are substantially increased in patients with operable stage non-small cell lung cancer (NSCLC) prior to lung resection surgery. This study tested the hypothesis that there is a decrease in MPs after surgical intervention. Between March 2012 and January 2015, 33 patients who had operable stage NSCLC were consecutively and prospectively enrolled into the study. Additionally, 31 healthy subjects who were consecutively enrolled in the study period served as age- and gender-matched controls. Circulating MPs (EDAc-MPs, EDAp-MPs, PDAc-MPs, PDAp-MPs) were measured by flow cytometry once in control subjects and twice (i.e., prior to and three months later after surgical intervention) in NSCLC patients. Compared with control subjects, these four types of circulating MPs were significantly higher in NSCLC patients prior to operation (all P < 0.005), but did not differ among the controls and NSCLC patients at 3 months after surgery (all P > 0.2). Additionally, a receiver operating characteristic curve (ROC) showed that these four types of MPs were significantly valuable predictors for detecting early stage NSCLC (all P < 0.004). Circulating MPs which were remarkably increased in the operable stage of NSCLC prior to surgery were substantially decreased 3 months later after surgery. These findings show that circulating MPs might be an accessory biomarker for monitoring those of NSCLC after receiving lung resection surgery.

Abstract
OBJECTIVES Surgery has been available for the treatment of mono-metastatic, non-small cell lung cancer (NSCLC) and promising overall survival was observed in some retrospective studies with selected patients. This study investigated whether the preoperative 18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) scan influences survival in this patient group. Furthermore we tried to identify other prognostic factors associated with survival and aimed to clarify if synchronous metastases are different from metachronous disease. METHODS Between 1994 and 2012, 181 patients underwent resection for solitary metastases. Sixty-six patients underwent surgery after an initial FDG-PET/CT scan, whereas 115 patients underwent conventional preoperative staging by a spiral CT scan. RESULTS The overall 5-year survival rate was 38.8%. The 5-year survival rates after preoperative evaluation by FDG-PET/CT and by conventional CT were 58% and 33%, respectively (p=0.01). A higher 5-year survival rate was observed in patients without thoracic lymph node involvement (pN0: 44% vs. pN1-3: 33%, p=0.028). In patients with a solitary pulmonary metastasis, we observed a 5-year survival rate of 45.7%, whereas in patients with extrapulmonary metastases, the 5-year survival rate was 27.1% (p=0.001). In patients with a locally limited primary lung cancer according to the pT descriptor, we observed a 5-year survival rate of 53.1%, whereas in patients with a pT>1 descriptor, the 5-year survival rate was 33.6% (p=0.016). By multivariate analyses, we showed that preoperative FDG-PET/CT evaluation, no thoracic lymph node metastases, and sole pulmonary metastatic disease were favorable predictors of survival, whereas the time of metastasis (synchronous vs. metachronous) and maximum standardized uptake value was not. CONCLUSIONS We conclude that resection of the primary tumor and metastasectomy for mono-metastatic NSCLC can be performed after a comprehensive evaluation with FDG-PET/CT. N-stage and the site of the oligometastases have a significant influence on overall survival.

Abstract
BACKGROUND Tumor metastases are the main reasons for oncotherapy failure. Paris polyphylla (Chinese name: Chonglou) has traditionally been used for its anti-cancer actions. In this article, we focus on the regulation of human lung cancer A549 cell metastases and invasion by Paris polyphylla steroidal saponins (PPSS). MATERIALS AND METHODS Cell viability was evaluated in A549 cells by MTT assay. Effects of PPSS on invasion and migration were investigated by wound-healing and matrigel invasion chamber assays. Adhesion to type IV collagen and laminin was evaluated by MTT assay. Expression and protease activity of two matrix metalloproteinases (MMPs), MMP-2 and MMP-9, were analyzed by Western blotting and gelatin zymography, respectively. RESULTS PPSS exerted growth inhibitory effects on A549 cells, and effectively inhibited A549 cell adhesion, migration and invasion in a concentration-dependent manner. Western blotting and gelatin zymography analysis revealed that PPSS inhibited the expression and secretion of MMP-2 and MMP-9 in A549 cells. CONCLUSIONS PPSS has the potential to suppress the migration, adhesion and invasion of A549 cells. PPSS could be a potential candidate for interventions against lung cancer metastases.

Abstract
Lung cancer is one of the most frequently diagnosed cancers and is the leading cause of cancer-related death worldwide. Non-small-cell lung cancer (NSCLC), a heterogeneous class of tumours, represents approximately 85% of all new lung cancer diagnoses. Tobacco smoking remains the main risk factor for developing this disease, but radon exposure and air pollution also have a role. Most patients are diagnosed with advanced-stage disease owing to inadequate screening programmes and late onset of clinical symptoms; consequently, patients have a very poor prognosis. Several diagnostic approaches can be used for NSCLC, including X-ray, CT and PET imaging, and histological examination of tumour biopsies. Accurate staging of the cancer is required to determine the optimal management strategy, which includes surgery, radiochemotherapy, immunotherapy and targeted approaches with anti-angiogenic monoclonal antibodies or tyrosine kinase inhibitors if tumours harbour oncogene mutations. Several of these driver mutations have been identified (for example, in epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK)), and therapy continues to advance to tackle acquired resistance problems. Also, palliative care has a central role in patient management and greatly improves quality of life. For an illustrated summary of this Primer, visit: http://go.nature.com/rWYFgg.

Abstract
BACKGROUND We hypothesized that lung cancer patient's circulating microparticles (Lc-MPs) could promote angiogenesis, blood flow in ischemic zone and ischemic recovery in rat critical limb ischemia (CLI). METHODS To investigate the impact of MP therapy on reversing the setting of CLI, adult-male Sprague-Dawley rats (n=50) equally randomized into sham control (SC) (group 1), SC-Lc-MPs (1.0 x 10(7) particles) (group 2), CLI (group 3), CLI-Hs-MPs (MPs from healthy-subject) (group 4), and CLI-Lc-MPs (group 5) were sacrificed by post-CLI day-14. RESULTS In vitro study showed that Lc-MPs enhanced VEGFR2 expression, angiogenesis, nitric-oxide production, and endothelial cell proliferation (all p<0.005). By days 7 and 14, Laser Doppler showed significantly higher ischemic/normal blood-flow ratio in groups 1 and 2 compared with group 3, and was significantly higher in group 4 and further elevated in group 5 (p<0.0001). Numbers of small vessels and endothelial markers (CD31(+) and vWF(+) cells) and protein expressions (eNOS, CD31) exhibited a pattern identical to Lasre Doppler among the five groups (all p<0.001). Pro-angiogenic factors (VEGF, CXCR4, SDF-1α, HGF) at cellular and protein levels showed a significant step-wise increase from groups 1 and 2 to groups 3, 4, and 5 (all p<0.001). Protein expressions of fibrotic (Smad3, TGF-β) and apoptotic (mitochondrial Bax, cleaved caspase 3, and PARP) biomarkers displayed an opposite pattern compared to that of Laser Doppler, whereas the protein expressions of anti-fibrotic (Smad1/5, BMP-2) and anti-apoptotic (Bcl-2) biomarkers showed an identical pattern compared with that of Laser Doppler among groups 1 to 3, and 5 (all p<0.001). CONCLUSION Administration of Lc-MPs augmented angiogenesis and restored blood flow in a rat of CLI.

Abstract
PURPOSE To prospectively compare the capabilities for TNM classification and assessment of clinical stage and operability among whole-body magnetic resonance (MR) imaging, coregistered positron emission tomographic (PET)/MR imaging with and without MR signal intensity (SI) assessment, and integrated fluorine 18 fluorodeoxyglucose (FDG) PET/computed tomography (CT) in non-small cell lung cancer (NSCLC) patients. MATERIALS AND METHODS The institutional review board approved this study, and written informed consent was obtained from each patient. One hundred forty consecutive NSCLC patients (75 men, 65 women; mean age, 72 years) prospectively underwent whole-body MR imaging, FDG PET/CT, conventional radiologic examinations, and surgical, pathologic, and/or follow-up examinations. All factors and clinical stage and operability were then visually assessed. All PET/MR examinations were assessed with and without SI assessment. One examination used anatomic, metabolic, and relaxation-time information, and the other used only anatomic and metabolic information. κ statistics were used for assessment of all factors and clinical stages with final diagnoses. McNemar test was used to compare the capability of all methods to assess operability. RESULTS Agreements of assessment of every factor (κ = 0.63-0.97) and clinical stage (κ = 0.65-0.90) were substantial or almost perfect. Regarding capability to assess operability, accuracy of whole-body MR imaging and PET/MR imaging with SI assessment (97.1% [136 of 140]) was significantly higher than that of MR/PET without SI assessment and integrated FDG PET/CT (85.0% [119 of 140]; P < .001). CONCLUSION Accuracies of whole-body MR imaging and PET/MR imaging with SI assessment are superior to PET/MR without SI assessment and PET/CT for identification of TNM factor, clinical stage, and operability evaluation of NSCLC patients.

Abstract
UNLABELLED Since the influential study by van Tinteren et al. published in The Lancet in 2002, there have been an increasing number of diagnostic randomized controlled trials (RCTs) investigating the benefit of PET. If they provide valid and useful information on the benefit, these studies can play an important role in informing guideline developers and policy makers. Our aim was to investigate how far the nuclear medicine community has come on its way from accuracy studies to RCTs and which issues we have to take into account in planning future studies. METHODS We conducted a systematic review of diagnostic randomized trials, in which PET was applied in only one arm. We covered published studies as well as registered unpublished and planned studies. We considered 3 quality indicators related to the usefulness of a trial to generate evidence for a clinical benefit: use of patient-important outcome, sufficient sample size, and current standard as comparator. RESULTS Fourteen published and 15 planned studies were identified. Five of the published studies and 12 of the planned studies did not use a patient-important outcome. Sample sizes were often so small that a significant result could be expected only under the assumption of a substantial reduction in the event rate. Comparators typically reflected the current standard. CONCLUSION If we consider the traditional areas of primary diagnosis, staging, and follow-up, then the number and quality of RCTs on PET is currently not sufficient to provide a major source for evidence-based decisions on the clinical benefit of PET. There will also be a future need in these traditional areas to deduce the clinical benefit of PET from the results of accuracy studies. The situation may be more favorable for the areas of treatment planning and response evaluation. Choice of patient-important outcomes and sufficient sample sizes are crucial issues in planning RCTs to demonstrate the clinical benefit of using PET.

Abstract
Cancer immunotherapy is a promising new approach to cancer treatment. It has been demonstrated that a high number of tumor-specific cytotoxic T cells (CTLs) is associated with increased disease-specific survival in lung cancer patients. Identification of superior CTL epitopes from tumor antigens is essential for the development of immunotherapy for malignant tumors. The EML4-ALK fusion gene was recently identified in a subset of non-small cell lung cancers (NSCLCs). In this study we searched for HLA-A*02:01- and HLA-A*24:02-restricted epitopes derived from EML4-ALK by screening predicted EML4-ALK-derived candidate peptides for the induction of tumor-reactive CTLs. Nine EML4-ALK-derived peptides were selected by a computer algorithm based on a permissive HLA-A*02:01 or HLA-A*24:02 binding motif. One of the nine peptides induced peptide-specific CTLs from human peripheral blood mononuclear cells. We were able to generate a peptide-specific CTL clone. This CTL clone specifically recognized peptide-pulsed T2 cells and H2228 cells expressing HLA-A*02:01 and EML4-ALK that had been treated with IFN-γ 48 h prior to examination. CTL activity was inhibited by an anti-HLA-class I monoclonal antibody (W6/32), consistent with a class I-restricted mechanism of cytotoxicity. These results suggest that this peptide (RLSALESRV) is a novel HLA-A*02:01-restricted CTL epitope and that it may be a new target for antigen-specific immunotherapy against EML4-ALK-positive cancers.

Abstract
The purpose of this study was to assess the efficacy of ¹⁸F-fluoro-2-deoxy-glucose uptake positron emission tomography (FDG-PET) for the prediction of outcome in definitive chemoradiotherapy (CRT) for esophageal cancer. We enrolled 56 patients with esophageal cancer treated with definitive CRT and examined by FDG-PET before treatment. We examined the correlation of the maximum standardized uptake value (SUVmax) in FDG-PET of the primary tumor with overall survival (OS), progression-free survival (PFS), local control (LC) and response of the primary tumor. After definitive CRT, 30 patients had a clinical complete response (CR), making the CR rate 54%. For all 56 patients, the 2-year OS rate, PFS rate and LC rates were 64%, 38% and 51%, respectively. We divided the patients into two groups according to SUVmax: SUVmax < 10 (low-SUV) and ≥10 (high-SUV). The 2-year OS rates in the low- and high-SUV groups were 100% and 41%, the PFS rates were 73% and 19%, the LC rates were 71% and 39%, and the CR rates were 100% and 32%, respectively. A univariate analysis revealed significant differences between the low- and high-SUV group in OS, PFS, LC and response (P = 0.0005, 0.0002, 0.048, and <0.0001, respectively). SUVmax and T stage were significantly associated with OS, PFS, LC and response. A multivariate analysis showed significant differences between the SUVmax <10 and ≥10 groups in overall survival and response (P < 0.05). Our result suggests that the SUVmax in FDG-PET of the primary tumor before treatment may have prognostic value for esophageal cancer.

Abstract
As an evolving technique, linear endobronchial ultrasound is becoming the first choice and standard of care not only to diagnose the malignant and benign mediastinal lesions but also to stage non-small cell lung cancer. Lung cancer is the leading cause of cancer-related mortality in both men and women. The disease causes more death compared with colorectal, breast, and prostate cancers combined in the United States. Staging of lung cancer determines the prognosis. The type of lung cancer has changed in the past few decades. The frequency of adenocarcinoma has increased, whereas squamous cell carcinoma now is less frequent. Determining the cell type and its molecular characteristics allow targeted treatments in adenocarcinoma. The diagnosis of indeterminate mediastinal lymph nodes or masses and staging lung cancer might be challenging. This article will review the principles and clinical utility of endobronchial ultrasound in mediastinal lesions.

Abstract
INTRODUCTION Spinal metastases of lung cancer occur frequently and lead to the risk of spinal cord compression. Our objective is to clarify the management of this disease, emphasizing, in particular the use of prognostic scores. BACKGROUND The first step is to evaluate the characteristics of the spinal lesion and its impact on the autonomy and quality of life of the patient. A clinical examination is complemented by imaging procedures, such as X-rays, MRI of the spine, and PET scanning. The precise characterization of the spinal lesion permits the calculation of a predictive score for mechanical stability. The characteristics of the disease (number of metastatic sites, therapeutic possibilities, co-morbidities) can be used in decision-making. VIEWPOINTS The use of prognostic scores is recommended by the Global Spine Tumour Study Group (GSTSG) for the management of spinal metastases. Among these scores, the most used are the Tokuhashi index, and the Tomita classification. They help to identify the treatment modalities, sometimes combined that might be used in the management: surgery, vertebral resection, tumour embolisation, radiotherapy, chemotherapy. CONCLUSIONS The management of spinal metastases of lung cancer should be multidisciplinary. Use of prognostic scores should be encouraged to identify optimal management.

Abstract
The identification of mediastinal lymph nodes (LNs) in lung cancer is an important step of treatment decision and prognosis prediction. The endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is widely used to assess the mediastinal LNs and tissue confirmation in lung cancer. As use of bronchoscopy or EBUS-TBNA has been increased, bronchial anthracofibrosis (BAF) has been detected frequently. Moreover, BAF is often accompanied by mediastinal lymphadenopathy and showed false-positive positron emission tomography uptake, which mimics metastatic lymphadenopathy in lung cancer patients. However, clinical implication of BAF during bronchoscopy is not well understood in lung cancer. We retrospectively reviewed 536 lung cancer patients who performed EBUS-TBNA and observed BAF in 55 patients. A total of 790 LNs were analyzed and macroscopic tissue pigmentation was observed in 228 patients. The adjusted odds ratio for predicting malignant LN was 0.46 for BAF, and 0.22 for macroscopic tissue pigmentation. The specificity of BAF and macroscopic tissue pigmentation for predicting a malignant LN was 75.7% and 42.2%, respectively, which was higher than the specificity of using LN size or standard uptake value on PET. In conclusion, BAF and macroscopic tissue pigmentation during EBUS-TBNA are less commonly found in malignant LNs than reactive LNs in Korean lung cancer patients.

Abstract
OBJECTIVES All lymph node stations but the para-aortic are accessible by a combination of endoscopic ultrasound and endobronchial ultrasound. We recently described an echographic-endoscopic technique for the biopsy of para-aortic (station 6) lymph nodes without traversing the thoracic aorta. This study reviewed our initial experience with this new technique. METHODS This first-in-human evaluation of the biopsy of station 6 mediastinal lymph nodes with curvilinear endoscopic ultrasound without arterial puncture used a retrospective case series design to study 12 consecutive patients who underwent this new technique. Station 6 lymph nodes were approached with a long fine needle aspiration approach (6-8 cm) through the proximal esophagus. The needle was passed through the esophagus into the mediastinum just medial to the left subclavian artery. It was then directed toward the para-aortic location (6-8 cm trajectory) to reach and enter the para-aortic lymph nodes without piercing the aorta or great vessels. RESULTS Successful cytologic diagnoses of station 6 lymph nodes were obtained in all cases (lymphocytes in all samples). No morbidity resulted from the procedure, nor was any observed at 30 days after the procedure. Patient anatomy may preclude safe access in certain situations. CONCLUSIONS Endoscopic ultrasound access of para-aortic (station 6) lymph nodes allows complete, minimally invasive mediastinal lymph node staging and diagnosis without traversal of the aorta. This technique, the final piece of the puzzle required for complete staging of the mediastinum with nonsurgical endoscopic techniques, is reproducible and safe.

Abstract
OBJECTIVES The aim of this study was to evaluate the usefulness of the tumor burden as characterized by the metabolic tumor volume (MTV) and total lesion glycolysis (TLG) measured by F-18 fluoro-2-deoxyglucose (F-18 FDG) PET-computed tomography (CT) in predicting recurrence-free survival (RFS) and overall survival (OS) in surgically resected non-small-cell lung cancer (NSCLC) patients. METHODS We retrospectively reviewed 91 patients with pathologically documented stages I-IIIA NSCLC. MTV and TLG were obtained according to various thresholds of the standard uptake value (SUV) of primary tumor using preoperative F-18 FDG PET-CT. We used comparison receiver-operating characteristic curve analysis to test the statistical significance of the differences among the multiple volumetric parameters calculated by various SUV cutoff values. RFS and OS were evaluated with the Kaplan-Meier method and Cox regression analysis. RESULTS On comparison receiver-operating characteristic curve analysis, no significant difference was found among the volumetric parameters calculated using various thresholds of SUV. Regardless of the thresholds, patients with smaller MTV and lower TLG showed longer RFS and OS. MTV and TLG measured by F-18 FDG PET-CT were found to have better predictive performance than SUVmax for recurrence and death. According to multivariate analyses, MTV2.5 was revealed as a significant prognostic factor for RFS. Tumor size over 3 cm was selected as a significant prognostic indicator of OS. CONCLUSION Volume-based parameters of F-18 FDG PET-CT may have a role in providing prognostic information in NSCLC patients who have received surgical treatment.

Abstract
INTRODUCTION Guidelines recommend that patients with clinical stage IIIA non-small cell lung cancer (NSCLC) undergo histologic confirmation of pathologic lymph nodes. Studies have suggested that invasive mediastinal staging is underutilized, although practice patterns have not been rigorously evaluated. METHODS We used the Surveillance, Epidemiology, and End Results-Medicare database to identify patients with stage IIIA NSCLC diagnosed from 1998 through 2005. Invasive staging and use of positron emission tomography (PET) scanning were assessed using Medicare claims. Multivariable logistic regression was used to identify patient characteristics associated with use of invasive staging. RESULTS Of 7583 stage IIIA NSCLC patients, 1678 (22%) underwent invasive staging. Patients who received curative intent cancer treatment were more likely to undergo invasive staging than patients who did not receive cancer-specific therapy (30% versus 9.8%, adjusted odds ratio, 3.31; 95% confidence interval, 2.78-3.95). The oldest patients (age, 85-94 years) were less likely to receive invasive staging than the youngest (age, 67-69 years; 27.6% versus 11.9%; odds ratio, 0.46; 95% confidence interval, 0.34-0.61). Sex, marital status, income, and race were not associated with the use of the invasive staging. The use of invasive staging was stable throughout the study period, despite an increase in the use of PET scanning from less than 10% of patients before 2000 to almost 70% in 2005. CONCLUSION Nearly 80% of Medicare beneficiaries with stage IIIA NSCLC do not receive guideline adherent mediastinal staging; this failure cannot be entirely explained by patient factors or a reliance on PET imaging. Incentives to encourage use of invasive staging may improve care.

Abstract
BACKGROUND The aim of this study was to analyze the impact of the induction chemoradiotherapy (IT) on the survival pattern in T3/T4-N0 non-small cell lung cancer (NSCLC) patients. METHODS The data of 71 patients treated from January 1992 to May 2007 were reviewed. Of these, 31 patients received IT prior to surgery (IT group: T3, 20 patients; and T4, 11 patients), and 40 directly underwent surgery (S group: T3, 34 patients; and T4, 6 patients). Survival rates were compared using the Kaplan-Meier analysis and the Cox proportional hazards models. RESULTS Mean ages were 62.5±9.9 years in the IT group and 67.7±7.1 in the S group. All patients but 1 completed the IT treatment and 27 patients (87%) were operated. A radical resection was possible in 21 patients (78%). In the IT group a complete pathologic response was obtained in 6 patients (22%), where 8 patients ended up in pI stage, 7 in pII stage, and 6 in pIII stage. The overall 5-year survival (long-term survival [LTS]) and disease-free 5-year survival (DFS) for the entire cohort were 40% and 34%, respectively. No significant differences were found when LTS in the IT group (44%) and in the S group (37%) were compared. At multivariate analysis, the completeness of resection was the only independent predictive factor (hazard ratio [HR]=5.18; 95% confidence interval [CI]=2.55 to 10.28) while Cox multivariate analysis (on the IT group only) confirmed the critical role of the pathologic downstaging (HR=4.62; 95% CI=1.54 to 13.89). CONCLUSIONS A multimodal strategy with IT treatment followed by surgery is a safe and reasonable treatment in T3/T4-N0 NSCLC patients, but no clear evidence of prognostic improvement may be assumed at the present time. Nevertheless, patients with radical resection and complete pathologic response have a very rewarding survival.

Abstract
OBJECTIVES To determine factors associated with diagnostic yield of ENB. METHODS In 112 consecutive patients referred to our department between March 2010 and December 2010 the diagnostic work-up for solitary pulmonary lesions included a FDG-PET-CT scan, and ENB in combination with ROSE. The final diagnosis was confirmed by histopathological evaluation of specimen obtained either by ENB, or - if ENB was not diagnostic - by CT-guided fine needle aspiration or surgery. RESULTS Thirty-seven (33%) subjects were female, mean age was 66.7 (±1.04) years. The mean diameter of lesions was 27mm (range: 6-46mm). In 83.9% the combination of PET-CT, ENB, and ROSE established a correct diagnosis, as defined by the definite histopathological result. 15.2% (17/112) of lesions were benign, and 84.8% (95/112) were malignant. For 112 procedures we observed a steep learning curve with a diagnostic yield of 80% and 87.5% for the first 30 and last 30 procedures, respectively. The diagnostic yield in lesions ≤20mm and >20mm in diameter was 75.6% and 89.6% (p=0.06), respectively. No significant difference in diagnostic yield was seen depending on lung function, and the localization of the lesions. Two cases (1.8%) of pneumothorax were seen during and up to 24h after bronchoscopy, none of them required a chest tube. CONCLUSION Diagnostic yield increased with experience but was independent from the size of the lesion, the localisation in the lungs, and lung function. The diagnostic yield of ENB can be as high as for CT-guided transthoracic biopsies but carries a significantly lower complication rate.

ZHONGGUO FEI AI ZA ZHI = CHINESE JOURNAL OF LUNG CANCER 2011; 13:700-5.

Abstract
BACKGROUND AND OBJECTIVE PET-CT have emerged as powerful imaging tools in radiotherapy to add information that might lead to a change in GTV definition in patients with non-small cell lung cancer (NSCLC). The aim of this study was to investigate the impact of co-registering 18F-FDG-PET-CT images on the gross tumor volume (GTV), the planning target volume (PTV), and critical organ dose in radiation therapy planning of NSCLC. METHODS Thirty patients with stage III NSCLC, referred for radical radiation therapy, underwent PET-CT scanning. GTV was delineated on the CT imaging and PET-CT fused imaging respectively. The two images were used to develop the radiotherapy planning at the GE Advantage Sim 6.0 workstation. Dose-volume histograms (DVH) parameters were selected to be paralleled to compare the quality of the two plans and the impact of PET-CT on radiation plan (RP) was further analyzed. RESULTS (1) PET-CT image changed the clinical stage: 3 patients (10%) upstaged and 3 patients (10%) downstaged. (2) PET-CT image altered GTV and PTV: GTV and PTV was decreased by PET-CT image fusion in 18 patients (60%) and was increased in 12 patients (40%). A significant (> 25%) treatment volume modification was observed in 17 patients (56.67%). (3) PET-CT image changed the parameters of DVH: to deliver the same target dose of 60 Gy in 30 fractions, all dose-volume characteristics decreased in treatment planning for the 18 patients with decreased PTV based on PET-CT; the issue was the contrary for the 12 patients who had enlarged PTV based on PET-CT. CONCLUSIONS The use of the co-registration of PET-CT significantly reduced inaccurate outlining of the GTV and/or to geographic misses.

Abstract
BACKGROUND Although the utility of blind biopsy in the detection of metastasis in the carina has been reported, submucosal fine needle aspiration (SMFNA) has not been evaluated. We investigated how SMFNA of the main carina and upper-lobe carina in addition to blind biopsy affect management of patients with NSCLC. METHODS Thirty-five patients were evaluated. During fiberoptic bronchoscopy (FOB), five blind biopsy and three SMFNA specimens were collected from normal-appearing main carina (n = 35) and/or upper-lobe carina (n = 18). Subjects were staged for operability using traditional staging system, without knowing the blind biopsy or SMFNA results. Then, patients were staged again after results were made known. RESULTS Thirty-five NSCLC patients were analyzed. The management of 12 patients (34%) was changed according to our results. Out of the patients, 8, 5 and one had microscopic metastasis in the main carina, ipsilateral upper-lobe carina and both, respectively. Although SMFNA were more diagnostic compared to blind forceps biopsy, there was no statistically difference between them. These procedures increased the success of detection of microscopic metastasis and the results changed management of those cases. CONCLUSION SMFNA adds valuable information to blind biopsy, and their combination changed the management in one quarter of our NSCLC patients.
