Abstract
BACKGROUND Lung adenocarcinoma (LUAD), the most common and lethal subtype of lung cancer, continues to be a major health concern worldwide. Despite advances in targeted and immune therapies, only a minority of patients derive substantial benefits. As a result, the urgent need for novel therapeutic strategies to improve lung cancer treatment outcomes remains undiminished. METHODS In our study, we employed the TIMER database to scrutinize TNFSF11 expression across various cancer types. We further examined the differential expression of TNFSF11 in normal and tumor tissues utilizing the TCGA-LUAD dataset and tissue microarray, and probed the associations between TNFSF11 expression and clinicopathological parameters within the TCGA-LUAD dataset. We used the GSE31210 dataset for external validation. To identify genes strongly linked to TNFSF11, we engaged LinkedOmics and conducted a KEGG pathway enrichment analysis using the WEB-based Gene SeT AnaLysis Toolkit. Moreover, we investigated the function of TNFSF11 through gene knockdown or overexpression approaches and explore its function in tumor cells. The therapeutic impact of ferroptosis inducers in tumors overexpressing TNFSF11 were also investigated through in vivo and in vitro experiments. Through these extensive analyses, we shed light on the potential role of TNFSF11 in lung adenocarcinoma, underscoring potential therapeutic targets for this malignancy. RESULTS This research uncovers the overexpression of TNFSF11 in LUAD patients and its inverse correlation with peroxisome-related enzymes. By utilizing gene knockdown or overexpression assays, we found that TNFSF11 was negatively associated with GPX4. Furthermore, cells with TNFSF11 overexpression were relatively more sensitive to the ferroptosis inducers. CONCLUSIONS Our research has provided valuable insights into the role of TNFSF11, revealing its negative regulation of GPX4, which could be influential in crafting therapeutic strategies. These findings set the stage for further exploration into the mechanisms underpinning the relationship between TNFSF11 and GPX4, potentially opening up new avenues for precision medicine in the treatment of LUAD.

Abstract
OBJECTIVE Injection of brucea javanica oil emulsion (IBJOE), one of Chinese patent drugs has been widely used for lung cancer (LC) in China, and is known to provide some favorable outcomes, in particular when it combined with conventional treatment. However, little available best evidence is known about its effect and safety. This paper aims to evaluate the effectiveness and safety of IBJOE plus chemoradiotherapy to alleviate symptoms of LC patients. METHODS A complete literature searching was conducted in databases including Chinese Biomedical Literature Database, China Academic Journals Full-text Database, Chinese Scientific Journals Database, the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE to identify randomized controlled trials (RCTs) of IBJOE with chemoradiotherapy versus chemoradiotherapy alone for LC patients regardless of blinding, duration of treatment or duration of follow-up. All searching dates were from the beginning to December 2011. Quality of the included studies was assessed using the method by Cochrane Reviewer Handbook, and data analysis was performed using RevMan 5.10 software developed by The Cochrane Collaboration. RESULTS The searching yielded over 1371 relevant citations, most of which did not meet the inclusion criteria. Finally, only 21 RCTs involving 1619 patients were included, and all the studies were of poor quality. Pooled analyses were performed to reveal that compared with chemoradiotherapy alone, IBJOE plus chemoradiotherapy had a better complete response rate (relative risk (RR) = 1.42; 95% CI 1.05 to 1.92; P = 0.02) and improved quality of life (RR = 1.83; 95% CI 1.63 to 2.07; P < 0.00001) measured by Karnofsky Performance Status scale. In addition, there was a significant difference on the outcome of long-term survival rate, level of immune function, and some incidences of adverse effects. CONCLUSIONS IBJOE plus chemoradiotherapy may have positive effects on LC patients in response rate, improvement of quality of life, and reducing incidences of some adverse effects compared with chemoradiotherapy alone. However, the results need to be viewed with caution because of low quality of the included studies.

Abstract
Background Microwave ablation (MWA) has attracted a worldwide attention gradually in treating inoperable pulmonary malignancies. However, in the lung tissues treated with MWA recurrence of tumor may still occur and few data in large patient groups till now were reported about the safety or effectiveness of microwave ablation in treating primary lung cancer and metastatic pulmonary malignancies. The purpose of this study is to evaluate the clinical curative effect (local control, survival data) MWA and its safety as well. Methods From 1 January 2005 to 1 January 2008, retrospective analyses, 69 patients underwent computed tomography (CT)-guided percutaneous MWA of pulmonary malignancies. All patients were deemed medically inoperable. The correlation of tumor sizes and local progression after ablation was analyzed and the survival rates within 3 years post surgery were compared between non-small-cell lung cancer and pulmonary metastases groups also. Results Pneumothorax was the most frequent complication and occurred in 24.64% patients after ablation. Neither needle track implantation was found nor did patient death occur in these patients within 30 days. The 1-, 2-, and 3-year overall survival rates were 66.7%, 44.9% and 24.6%, respectively. The overall survival rates for NSCLC patients in 1 year, 2 years, and 3 years were 75.0%, 54.2%, and 29.2%, respectively. The overall survival rates for pulmonary metastatic tumor patients in 1 year, 2 years, and 3 years were 47.6%, 23.8%, and 14.3%, respectively. The recurrence-free survival rates for NSCLC patients in 1 year, 2 years, and 3 years were 72.9%, 50.0%, and 27.1%, respectively. The mortality rates for pulmonary metastatic tumor patients in 1 year, 2 years, and 3 years were 47.6%, 19.0%, and 14.3%, respectively. Conclusions Percutaneous microwave coagulation therapy was one safe and effective method and could be beneficial for the improvement of inoperable pulmonary malignancies treatment effect.

Abstract
RATIONALE AND OBJECTIVES The aim of this review was to evaluate the diagnostic properties of (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) or PET/computed tomography (CT) and bone scintigraphy in the detection of osseous metastases in patients with lung cancer. MATERIALS AND METHODS MEDLINE was searched for relevant original articles published between January 1995 and August 2010. Inclusion criteria were as follows: FDG-PET or PET/CT and bone scintigraphy was carried out to detect bone metastases in patients with lung cancer, sufficient data were presented to construct a 2 × 2 contingency table, and histopathologic analysis and/or close clinical and imaging follow-up and/or radiographic confirmation by multiple imaging modalities was used as the reference standard. Two reviewers independently extracted data related to research design, sample size, imaging techniques, technical characteristics, reference standards, methods of imaging interpretation, and totals of true-positives, false-positives, true-negatives, and false-negatives. Stata was used to obtain per patient and per lesion pooled estimates of sensitivity, specificity, and positive and negative likelihood ratios, and areas under summary receiver-operating characteristic curves (AUCs) were calculated. RESULTS The pooled patient-based sensitivity of FDG-PET or PET/CT was 0.93 (95% confidence interval [CI], 0.88-0.96), specificity was 0.95 (95% CI, 0.91-0.98), and the AUC was 0.94. The pooled sensitivity of bone scans was 0.87 (95% CI, 0.79-0.93), specificity was 0.82 (95% CI, 0.62-0.92), and the AUC was 0.91. The pooled lesion-based sensitivity of FDG-PET or PET/CT was 0.93 (95% CI, 0.84-0.97), specificity was 0.91 (95% CI, 0.80-0.96), and the AUC was 0.97. The pooled sensitivity of bone scans was 0.92 (95% CI, 0.87-0.95), specificity was 0.57 (95% CI, 0.09-0.95), and the AUC was 0.92. CONCLUSIONS Although FDG-PET or PET/CT has higher sensitivity and specificity than bone scintigraphy, further research with a less biased design is needed to determine the most efficacious imaging modality for the detection of metastatic lung cancer.

Abstract
The efficacy of high dose-rate endobronchial radiotherapy (HDERT) against proximal airway obstruction that results from lung cancer has not been thoroughly evaluated. This study retrospectively reviewed tumor/obstruction characteristics prior to therapy, interventions applied, symptoms before and after intervention, complications, and survival of all patients with proximal airway obstruction resulting from lung cancer who received HDERT between 1995 and 2003 in a tertiary teaching center. Thirty-four (34) patients received HDERT, while 28 had additional treatment (external radiotherapy = 23, neodymium yttrium aluminum garnet laser ablation = 9, stenting = 7, electrosurgery = 5, cryosurgery = 3, and photodynamic therapy = 1). Sixteen (16) patients developed complications, the most frequent being respiratory failure and bronchial-wall necrosis, while 19 experienced symptomatic relief. The median (95% confidence interval) survival of these 34 patients was 7.8 (5.9-9.8) months, significantly longer (p = 0.004) than a historic control of 3.9 (3.7-7.1) months from the Cleveland Clinic Foundation, in Cleveland, OH, and comparable to other previous reports. No single factor predicted complications or symptomatic relief. However, female gender, presence of only one symptom, absence of fatigue/weight loss, >1 HDERT sessions, and postprocedure symptom relief were associated with improved survival. Contemporary HDERT with or without additional treatment modalities is effective against central airway compromise resulting from lung cancer.

Abstract
A 39-year-old man living with AIDS presented with a swollen face. He was found to be HIV infected after presenting with Coccidioides pneumonia 2 years previously and was placed on daily fluconazole and then on highly active antiretroviral therapy. Computed tomography confirmed superior vena cava obstruction secondary to lymphadenopathy. Biopsy confirmed coccidioidomycosis with no evidence of malignancy. To our knowledge, this is the first description of superior vena cave syndrome secondary to coccidioidomycosis and the first description of immune reconstitution inflammatory syndrome involving Coccidioides.

Abstract
PURPOSE To investigate whether 201Tl uptake is associated with cell proliferation and angiogenesis in non-small-cell lung carcinoma (NSCLC). METHODS Eighty-four patients with scheduled NSCLC underwent 201Tl single photon emission computed tomography (SPECT) imaging: 15 min (early scan) and 240 min (delayed scan) after intravenous injection of 111 MBq of 201Tl chloride. 201Tl indices were calculated on early images (early ratio: ER) and delayed images (delayed ratio: DR). The retention index (RI) was also calculated from these two parameters. Using surgically resected cancer specimens (54 adenocarcinoma, 24 squamous cell carcinoma (SCC), six large-cell carcinoma), immunohistochemical stains for both Ki-67 (MIB-1 index) and CD34 were performed to examine the proliferative activity and the micro-vessel density (MVD), respectively. RESULTS The mean value of 201Tl index was 1.69+/-0.77 (ER) and 2.31+/-1.08 (DR). The average RI was 42.6+/-42.9%, respectively. Both DR and RI positively correlated with MIB-1 index (r = 0.68, P < 0.05 and r = 0.52, P < 0.05). When we analyse adenocarcinoma and SCC separately, there was a significant positive correlation (r = 0.62, P < 0.05) between RI and MIB-1 index in adenocarcinoma but not in SCC (r = 0.20, P = NS). The value of ER positively correlated with MVD (r = 0.75, P < 0.05). It demonstrated strong positive correlation with both histological types (adenocarcinoma: r = 0.80, P < 0.05, SCC: r = 0.66, P < 0.05). CONCLUSION 201Tl SPECT imaging is effective non-invasive method for assessing both the proliferation and the angiogenesis in NSCLC. Both DR and RI are useful indicators for assessing cancer cell proliferation in lung adenocarcinoma. ER is a useful marker for assessing the tumour angiogenesis in NSCLC.

Abstract
Percutaneous radiofrequency thermal ablation (RFA) has been used to treat primary and secondary liver tumors under ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI) guidance for the past decade [Park et al., Radiol Clin North Am 38:545-561, 2000; Siperstein and Gotomirski, Cancer J 6:S293-S301, 2000; Kelekis et al., Eur Radiol 13:1100-1105, 2003]. RFA is a low-cost, minimally invasive treatment that has recently attracted attention for treating tumors in different solid organs with promising results [Dupuy and Goldberg, J Vasc Interv Radiol 12:1135-1148, 2001; Friedman et al., Cardiovasc Intervent Radiol 27:427-434, 2004]. It can be provided with minimal hospitalization, and experienced practitioners have reported low complication rates [Dupuy and Goldberg, J Vasc Interv Radiol 12:1135-1148, 2001; Livraghi et al., Radiology 226:441-451, 2003]. Patients with lung malignancies (primary lung cancer or pulmonary metastases), who cannot be operated, might be candidates for RFA treatment. It can also be used in association with other treatments (i.e., chemotherapy, radiotherapy) for better disease control. Combination of the above with RFA may help reduce morbidity and mortality. Many ways to apply energy to the tumor exist (monopolar and bipolar RFA, microwave, laser, brachytherapy). In this review we will focus on expandable monopolar systems, which despite their deficiencies are the most popular in the interventional radiology sector.

Abstract
Lung cancer is one of the leading causes of death in the world. The underlying cause for lung cancer has been attributed to various factors that include alteration and mutation in the tumor suppressor genes. Restoration of normal function of the tumor suppressor gene is a potential therapeutic strategy. Recent studies have identified a group of candidate tumor suppressor genes on human chromosome 3p21.3 that are frequently deleted in human lung and breast cancers. Among the various genes identified in the 3p21.3 region, we tested the antitumor activity of the FUS1 gene in two human non-small-cell lung cancer (NSCLC) xenografts in vivo. Intratumoral administration of FUS1 gene complexed to DOTAP:cholesterol (DOTAP:Chol) liposome into subcutaneous H1299 and A549 lung tumor xenograft resulted in significant (P = .02) inhibition of tumor growth. Furthermore, intravenous injections of DOTAP:Chol-FUS1 complex into mice bearing experimental A549 lung metastasis demonstrated significant (P = .001) decrease in the number of metastatic tumor nodules. Finally, lung tumor-bearing animals when treated with DOTAP:Chol-FUS1 complex demonstrate prolonged survival (median survival time: 80 days, P = .01) compared to control animals. This result demonstrates the potent tumor suppressive activity of the FUS1 gene and is a promising therapeutic agent for treatment of primary and disseminated human lung cancer.

Abstract
The natural history of bronchogenic carcinoma shows that 42% of patients are diagnosed with cancer-related neurological complications either at initial presentation or at follow-up that can be separated in 3 different categories: - locoregional involvement of cervicothoracic nerves (recurrent laryngeal nerves, phrenic and vagus nerves, brachial plexus and sympathetic cervical chains), - metastatic disease characterized by intracranial lesions (brain, meningeal, ependymal and pituitary metastases) and spinal (extradural, subarachnoid and medullary metastases) lesions, - paraneoplastic syndromes including limbic encephalitis, Lambert-Eaton syndrome and paraneoplastic cerebellar degeneration. These neurological disorders usually are associated with advanced cancer for which radical surgical management seldom is indicated. All imaging studies performed at the time of initial staging for bronchogenic carcinoma should therefore be carefully reviewed in order to detect signs that could suggest the presence of one or several neurological complications. The goals of this paper are to describe the clinical signs and to illustrate the imaging features of neurological complications related to bronchogenic carcinoma at conventional radiography, CT and MRI.

Abstract
PURPOSE Review the surgical treatment of 56 patients at a single institution of early stage non-small cell lung carcinoma (NSCLC). Briefly review the literature to report the current indications for limited pulmonary resection. Discuss newer methods of assessing early stage NSCLC. METHODS We reviewed 56 lobectomies performed at the Biloxi Veterans Administration Medical Center from January 1992 to December 1997 for NSCLC to report the incidence of N1 positive lymph nodes and survival data. Additionally, a search of PubMed, Ovid, and MDConsult.com, using search parameters of non-small cell lung carcinoma, limited pulmonary resection, lobectomy, and comorbidity, were used to determine indications for treating non-small cell lung carcinoma. RESULTS N1 positive lymph nodes occurred in 11 out of 56 patients; 4 were identified preoperatively. In this sample, 21 patients were Stage IA, 21 Stage IB, 6 Stage IIA, and 8 Stage IIB, and their 4-year median survival was as follows: (IA) greater than 44.80 months, (IB) greater than 48.0 months, (IIA) greater than 25.28 months, and (IIB) = 11.18 months. Four-year survival rates by stage were IA= 10/21 (47.62%), IB= 14/21 (66.67%), IIA= 2/6 (33.33%), and IIB= 0/8 (0.0%). CONCLUSIONS The 4-year survival data we reviewed were less favorable than is reported by others. Patient medical comorbidity, patient age, and sample size are thought to account for this difference. According to our literature review, reasons for limited pulmonary resection include poor physical performance, marginal lung reserve, synchronous bilateral tumors, and superior sulcus tumors (T3) in which the tumor primarily invades the chest wall. Heavier consideration of these indications might have improved the outcomes seen in this population.

Abstract
STUDY OBJECTIVES The findings from conventional imaging modalities, such as chest CT, are frequently unreliable in patients with lung cancer. This study was designed to compare the relative diagnostic accuracies and utility of the two most widely used functional imaging examinations, F-18-2-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) and (99m)Tc depreotide scintigraphy, for the diagnosis and staging of lung cancer. DESIGN Prospective, experimental investigation. SETTING Academic medical center. PATIENTS One hundred sixty-six subjects with suspected lung cancer were enrolled in the study. INTERVENTIONS Whole-body and single-photon emission CT imaging of the chest was performed after IV administration of (99m)Tc depreotide. Attenuation-corrected FDG PET imaging was performed after IV administration of FDG. Image findings were compared with the biopsy results or clinical follow-up. MEASUREMENTS AND RESULTS In 157 subjects with evaluable lung lesions, the sensitivities and specificities for detecting malignant disease (95% confidence intervals) of FDG PET are 96% (90 to 98%) and 71% (54 to 85%), and of (99m)Tc depreotide are 94% (88 to 98%) and 51% (34 to 68%). In the 139 subjects with available complete staging data, FDG PET correctly staged 76 of 139 patients (55%), and (99m)Tc depreotide correctly staged 63 of 139 patients (45%). CONCLUSIONS The sensitivity for detection of lung cancer in the primary lesion is equally high for FDG PET and (99m)Tc depreotide. The specificity is superior for FDG PET. The staging accuracy of FDG PET and (99m)Tc depreotide is similar, but when read with the chest CT neither scintigraphic examination is sufficiently accurate to stage patients with non-small cell lung cancer.

Abstract
Primary lung cancer is the most frequently diagnosed malignancy in the world and the leading cause of death from cancer [1]. When the initial diagnosis is made, most cases are inoperable or the patients' condition does not permit surgical interventions [2]. For patients with inoperable lung cancer, percutaneous radio-frequency thermal ablation (RFA) under CT guidance represents an alternative and minimally invasive treatment. It can also be applied in combination with radiation therapy and chemotherapy. We report three cases treated by percutaneous CT-guided RF ablation, from which two had post-operative recurrent tumor and one was inoperable.

Abstract
PURPOSE The aim of this study was to evaluate the relationship between 201Tl tumor uptake, chemotherapeutic response, metastasis, p53 status and survival in non-small cell lung cancer (NSCLC). METHODS A total of 23 patients underwent 201Tl SPECT. In 9 patients, 2nd 201Tl SPECT study were performed 1 week after the 3rd cycle of chemotherapy (ChT), and early (ER) and delayed (DR) tumor/normal lung ratios and retention indices (RI) were obtained. In 15 patients p53 status was assayed with immuno-histochemical staining. The patients were divided into subgroups after the 3rd cycle of ChT; responders [R(+) (n = 10)] and non-responders [R(-) (n = 13)], distant metastasis [(M1) n = 11] and [(M0) n = 12], and mutant p53 status [p(+) n = 7, p53(-) n = 8]. RESULTS The differences for ER, DR and RI values between all of the subgroups were not statistically significant. ER and DR of responders decreased significantly after ChT; from to 2.46 to 1.36 (p = 0.04) and 2.29 to 1.53 (p = 0.04), respectively. In the non-responder group, both ER and DR slightly increased after ChT (p > 0.05). CONCLUSION Our results suggest that in NSCLC, there was a weak correlation between higher 201Tl ratios and positive response to chemotherapy, absence of distant metastasis, and p53(-) status. Significant 201Tl uptake decrease after chemotherapy indicates that delayed 201Tl uptake can be used in evaluating the chemotherapeutic response.

Abstract
The aim of this study was to evaluate [18F]fluorodeoxyglucose ( F-FDG) imaging of recurrent or inoperable lung cancer using a hybrid positron emission tomography (PET) device of the third generation. Examinations were compared with the results of conventional staging. Thirty-six patients suffering from recurrent or primarily inoperable lung cancer (29 men, seven women; age 64.8+/-12.0 years) were examined using hybrid PET (Marconi Axis gamma-PET ) 60 min after injection of 370 MBq F-FDG. The data obtained were reconstructed iteratively. All patients received a computed tomography (CT) scan using either the spiral or multislice technique. All lesions suspicious for primary or recurrent tumour were verified by biopsy; mediastinal lymph nodes were considered as malignant, when positive histology or a small axis diameter of greater than 1 cm measured with CT in addition to progression of clinical course was found. Distant metastases were diagnosed by CT and bone scintigraphy. Using hybrid PET all lesions showed a focally elevated glucose metabolism. Lymph node involvement of the ipsilateral peribronchial and hilar station (N1) was identified in 24/26 cases (92%), in 26/29 cases (90%) of ipsilateral central manifestation (N2) and in 11/13 (85%) cases of central contralateral or supraclavicular lymphatic infestation (N3). Pulmonary spread in hybrid PET was found in 4/8 cases (50%), whereas mainly lung metastases with a diameter of 1.5 cm and smaller were missed. Pleural involvement diagnosed by CT was verified in 4/5 patients. All four patients with bony metastases in conventional staging also presented with positive findings in hybrid PET (8/9 lesions). Concordance with conventional staging was found in 28/36 of patients (78%). In 4/36 patients (11%) unknown sites of tumour were detected leading to therapeutic consequences in three patients after radiological confirmation. Hybrid PET would have led to an understaging in four cases (11%), resulting theoretically in inefficient treatment in two patients. Hybrid PET for F-FDG imaging in the staging of recurrent or primarily inoperable lung cancer supplied equal (78%) or more information (11%) compared to conventional staging procedures. Using the information of hybrid PET alone, 11% of the patients would have been understaged. We conclude that hybrid PET has the potential for use as an additional staging tool in this subgroup of patients, providing supplementary information compared to conventional staging modalities.

Abstract
Patients with advanced non-small-cell lung carcinoma (NSCLC) have poor prognoses and experience negative sequelae of disease. Patients often suffer from dyspnea and/or hemoptysis, with overall pulmonary compromise. Patients with advanced, inoperable disease have limited options for treatment. This study summarizes our early experience and findings using photodynamic therapy (PDT) as an effective modality in the palliation of hemoptysis, dyspnea, and physical airway obstruction in cases of inoperable lung cancer. A retrospective review was conducted for the first 10 patients diagnosed with stage III/IV obstructive NSCLC who underwent PDT at our institution. Endobronchial lesions were identified by bronchoscopy. Treatments were initiated 48 hours after intravenous injection of 2 mg/kg of the photosensitizing agent porfimer sodium (Photofrin, QLT PhotoTherapeutics, Vancouver, BC). The porfimer sodium was then activated by illumination with a 630 nm wavelength light using a Coherent argon ion laser through a flexible bronchoscope. Repeated bronchoscopies were performed 1-3 days following initial PDT for evaluation and airway debridement. In 8 cases, a second treatment of PDT was administered within 72 hours of the first injection. One patient received a third treatment several months later. Three patients also received endobronchial stents after PDT. Overall, all 10 patients responded to PDT. Physical airway obstruction was reduced in all patients, with a noted improvement in bronchoscopic luminal diameter. Acute hemoptysis resolved in all 7 symptomatic patients. Median survival was 5.5 months post-PDT, while median survival postdiagnosis was 10.5 months. Three patients are alive at the time of this review at 5-21 months following therapy. Patients with unresectable late-stage NSCLC have few options for treatment. Our early experience with PDT indicates effective relief of hemoptysis, dyspnea, and airway obstruction and improves their quality of life.
