Abstract
PURPOSE The incidence of multiple primary malignancies (MPM) involving lung cancer has increased in recent decades. There is an urgent need to clarify the genetic profile of such patients and explore more efficacious therapy for them. EXPERIMENTAL DESIGN Peripheral blood samples from MPM involving patients with lung cancer were assessed by whole-exome sequencing (WES), and the identified variants were referenced for pathogenicity using the public available database. Pathway enrichment analysis of mutated genes was performed to identify the most relevant pathway. Next, the effects of mutations in relevant pathway on function and response to targeted drugs were verified by in vitro and in vivo experiments. RESULTS Germline exomes of 71 patients diagnosed with MPM involving lung cancer were sequenced. Pathway enrichment analysis shows that the homologous recombination repair (HRR) pathway has the strongest correlation. Moreover, HRR genes, especially key Holliday junction resolvases (HJR) genes (GEN1, BLM, SXL4, and RMI1), were most frequently mutated, unlike the status in the samples from patients with lung cancer only. Next, we identified a total of seven mutations in HJR genes led to homologous recombination DNA repair deficiency and rendered lung cancer cells sensitive to PARP inhibitor treatment, both in vitro and in vivo. CONCLUSIONS This is the first study to map the profile of germline mutations in patients with MPM involving lung cancer. This study may shed light on early prevention and novel targeted therapies for MPM involving patients with lung cancer with HJR mutations.

[PMID: 37102045 PMCID: PMC10125234 DOI: 10.21315/mjms2023.30.2.13] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 10/06/2022] [Indexed: 04/28/2023] Open
Abstract
Background Cancer is the second greatest cause of death and disability after cardiovascular disease. Objective To determine the effects of exercise training in patients with lung cancer during chemotherapy treatment. Methods A randomised clinical trial was conducted in Shaukat Khanum Memorial Cancer Hospital and Institute of Radiotherapy and Nuclear Medicine (IRNUM) Peshawar. A total of 40 participants were randomly divided into two groups: i) the Experimental group (EG, n = 20) and ii) Control group (CG, n = 20). Both groups received exercise training for 4 weeks, with five sessions per week. The EG received pulmonary rehabilitation and aerobic training. The CG received only pulmonary rehabilitation. Both groups were evaluated at baseline and after 6 weeks through Mindful Attention Awareness Scale (MAAS) Urdu version, Six Minute Walk Test (6MWT), digital spirometry, Borgs scale, Hospital Anxiety and Depression Scale (HADs) and Visual Analogue Scale (VAS). Results Both the EG and CG showed significant improvement in MAAS scores at post-study with a (P < 0.001). The scores of 6MWT were improved significantly in both groups after intervention with a (P = 0.001). The patient's anxiety scores were significantly improved in both groups after intervention with a (P < 0.001), while depression scores were also improved considerably between the two groups at post-level with a (P < 0.001). Regarding spirometry value, both groups showed significant improvement after intervention for forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC (P < 0.001). Both groups show significant differences in patient pain intensity and dyspnea at post-level with P < 0.001. Conclusion This study concluded that pulmonary rehabilitation along with aerobic training can be more effective than pulmonary rehabilitation alone for patients with lung cancer during chemotherapy treatment.

Long non-coding RNA LSAMP-1 is down-regulated in non-small cell lung cancer and predicts a poor prognosis. Cancer Cell Int 2022; 22:181. [PMID: 35524253 PMCID: PMC9074231 DOI: 10.1186/s12935-022-02592-0] [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: 09/13/2021] [Accepted: 04/18/2022] [Indexed: 12/05/2022] Open
Abstract
Background Long noncoding RNAs (lncRNAs) are emerging as master regulators for gene expression and thus play a vital role in human tumorigenesis and progression. But the involvement of novel lncRNAs in non-small cell lung cancer (NSCLC) remains largely unelucidated. Methods A total of 170 NSCLC and their adjacent non-tumor tissues were enrolled to detect the expression of Lnc-LSAMP-1 by RT-qPCR. The effects of Lnc-LSAMP-1 on cell proliferation, migration, invasion and drug-sensitivity were determined by in vitro and in vivo experiments. The proteins that interact with Lnc-LSAMP-1were confirmed by RNA pull-down assay. RNA-sequencing were used to identify the potential targets of Lnc-LSAMP-1 in NSCLC. Results We found that Lnc-LSAMP-1 was significantly down-regulated in 170 cases of NSCLC tissues when compared to their adjacent non-cancerous tissues. Loss expression of Lnc-LSAMP-1 was notably correlated with unfavorable prognosis of NSCLC patients. The ectopic expression of Lnc-LSAMP-1 drastically inhibited lung cancer cell proliferation, viability, invasion and migration ability, arrested cell cycle and facilitated apoptosis. Chemotherapy sensitization experiments showed that over-expressed Lnc-LSAMP-1 enhanced the inhibition of cell proliferation induced by TKI. Mechanistically, Lnc-LSAMP-1-LSAMP formed a complex which could protect the degradation of LSAMP gene, and thus exerted crucial roles in NSCLC progression and TKI targeted treatment. Conclusions Consequently, our findings highlight the function and prognostic value of Lnc-LSAMP-1 in NSCLC and provide potential novel therapeutic targets and prognostic biomarkers for patients with NSCLC.

Abstract
Abstract
Introduction
A number of articles focus on functioning with lung cancer. However, there are no articles on factors which result in the inability to live independently in the course of this disease. This study assesses risk factors regarding the inability to live independently among individuals with lung cancer.
Materials and Methods
This study included 134 patients who displayed interest in obtaining a certificate of the inability to live independently.
Results
Over the study period, 75% of the patients obtained the certificate of inability to live independently (group A) and 25% of them did not obtain the certificate (group B). In group A, 56.4% of individuals were men, and in group B, 42.4% of them were men. In group A, 11.8% of patients were diagnosed with small cell lung cancer; no such case was found in group B. Metastases were revealed in 83.2% of patients from group A and in 57.6% from group B. Patients from group A had a significantly lower score in the Barthel Index for Activities of Daily Living and lower body mass index compared with those from group B.
Conclusions
Information on body mass index, histopathological diagnosis, and the presence of metastases is useful in assessing the risk of being unable to live independently in patients with lung cancer. The Barthel Index for Activities of Daily Living is helpful in assessing the inability to live independently.

Front Oncol 2021; 10:568433. [PMID: 33520694 PMCID: PMC7840895 DOI: 10.3389/fonc.2020.568433] [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: 06/02/2020] [Accepted: 11/30/2020] [Indexed: 12/24/2022] Open
Abstract
Lung cancer is one of the most prevalent and life-threatening neoplasias worldwide due to the deficiency of ideal diagnostic biomarkers. Although aberrant glycosylation has been observed in human serum and tissue, little is known about the alterations in bronchoalveolar lavage fluid (BALF) that are extremely associated with lung cancer. In this study, our aim was to systematically investigate and assess the alterations of protein glycopatterns in BALF and possibility as biomarkers for diagnosis of lung cancer. Here, lectin microarrays and blotting analysis were utilized to detect the differential expression of BALF glycoproteins from patients with 80 adenocarcinomas (ADC), 77 squamous carcinomas (SCC), 51 small cell lung cancer (SCLC), and 73 benign pulmonary diseases (BPD). These 281 specimens were then randomly divided into a training cohort and validation cohort for constructing and verifying the diagnostic models based on the glycopattern abundances. Moreover, an independent test was performed with 120 newly collected BALF samples enrolled in the double-blind cohort to further assess the clinical application potential of the diagnostic models. According to the results, there were 15 (e.g., PHA-E, EEL, and BPL) and 14 lectins (e.g., PTL-II, LCA, and SJA) that individually showed significant variations in different types and stages of lung cancer compared to BPD. Notably, the diagnostic models achieved better discriminate power in the validation cohort and exhibited high accuracies of 0.917, 0.864, 0.712, 0.671, and 0.781 in the double-blind cohort for the diagnosis of lung cancer, early stage lung cancer, ADC, SCC, and SCLC, respectively. Taken together, the present study revealed that the abnormally altered protein glycopatterns in BALF are expected to be novel potential biomarkers for the identification and early diagnosis of lung cancer, which will contribute to explain the mechanism of the development of lung cancer from the perspective of glycobiology.

Abstract
INTRODUCTION Lung cancer is the leading cause of cancer death among men and women, accounting for more fatalities than colon, breast, and prostate cancers combined. Smoking causes about 85% of all lung cancers in the United States and is the single greatest risk factor. In 2013, the US Preventive Services Task Force (USPSTF) published initial guidelines for low-dose computed tomography lung cancer screening (LCS) among patients 55-80 years old, with a 30-pack-year history, who are current smokers or who quit within the previous 15 years. Smoking prevalence is higher among military personnel compared to the civilian population, demonstrating a need for vigilant screening. MATERIALS AND METHODS A retrospective review of Naval Medical Center San Diego's (NMCSD) LCS data was conducted to examine screening numbers, lung cancer rates, and initial analysis of screening results. Patients were referred for screening if they met the USPSTF criteria. Between September 2013 and September 2018, 962 patients underwent LCS. A total of 1758 examinations were performed, including follow-up and annual surveillance examinations. The American College of Radiology's Lung CT Screening Reporting and Data System (Lung-RADS) was used to classify lung nodules' risk for malignancy. RESULTS On this initial analysis, 42 enrolled patients received the diagnosis of lung cancer detected by screening. The initial calculated lung cancer rate is 4.4% (42/962) over the 5-year reporting period. The lung cancer rate among those patients with a Lung-RADS score of 3 or 4 was 31% (42/135). Thirty-seven patients were classified as having non-small cell lung cancer (NSCLC), while five were classified as having small cell lung cancer. Of the 37 NSCLC patients, 76% (28/37) were diagnosed at stage I and II, 11% (4/37) were diagnosed at stage III, and 13% (5/37) were diagnosed at stage IV. The total number of years a person smoked was a significant risk factor (P = 0.004), but not pack-years a person smoked (P = 0.052). CONCLUSIONS These preliminary results demonstrate the success of a Military Treatment Facility (MTF)-based LCS Program in the detection of early stage lung cancer. Earlier stage detection may result in better health outcomes for affected patients. In the population studied, duration of smoking proved to be more significant than pack-years in predicting lung cancer risk. These results validate the newly dedicated resources and continued efforts to strengthen the LCS program at NMCSD and across MTFs.

Abstract
This study aimed to assess the impact of exercise training in patients with lung cancer on several outcomes compared to a control group. Results suggest that exercise programs in patients with lung cancer are a practical and beneficial intervention for enhancing mobility and physical fitness. Purpose: The aim of this study was to perform a randomized trial to assess the impact of exercise training in patients with non–small cell lung cancer during chemotherapy on several outcomes in comparison to a control group (CG). Methods: The exercise training group (ETG) consisted of 20 patients and the CG consisted of 10 patients. In the ETG, a 4-wk in-hospital exercise training program was performed in 2-wk cycles interspersed with consecutive rounds of chemotherapy with cytostatic drugs. The exercise training program was individualized and included warm-up, respiratory muscle exercise, training on a cycle ergometer or treadmill, and Nordic walking. CG participants were assessed before and after 6 wk of chemotherapy alone. Results: Comparing pre- and post-intervention values, the ETG demonstrated an increase in 6-min walk distance (486 ± 92 vs 531 ± 103 m, P = .01). In a battery of physical performance tests: Up and Go Test (6.3 ± 1.0 vs 6.0 ± 1.1 sec, P = .01); chair stand (13.3 ± 2.8 vs 14.3 ± 3.4 repetitions, P = .001); and arm curl (18.4 ± 3.1 vs 20.4 ± 3.5 repetitions, P = .001) all improved significantly. Spirometry values also improved: FEV1 % predicted (76 ± 16 vs 84 ± 15, P = .01), FVC % predicted (87 ± 14 vs 95 ± 13, P = .01), and FEV1/FVC (73 ± 13% vs 76 ± 12%, P = .04). The exercise training was well tolerated, without any adverse events due to exercise. There were no significant improvements in the CG. Conclusions: This study suggests that planned, individualized, and supervised exercise programs in patients with advanced lung cancer during chemotherapy are a practical and beneficial intervention for enhancing mobility and physical fitness.

Epidemiology of lung cancer in northeast of Iran: A 25-year study of 939 patients. Med J Islam Repub Iran 2020; 34:17. [PMID: 32551306 PMCID: PMC7293801 DOI: 10.34171/mjiri.34.17] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Indexed: 01/10/2023] Open
Abstract
Background: Lung cancer (LC) is a global public health priority. In this study, the epidemiology and current trends of primary LCs were investigated in northeast of Iran.
Methods: Demographic and pathologic records of primary LCs during 1985-2012 in Mashhad (capital of northeast of Iran) were reviewed. Data were obtained from archives of the largest referral oncologic hospital and the only private outpatient radiation-oncologic clinic in the region. To investigate trends, study duration was classified into 3 periods: 1985-1995, 1995-2005, and 2005-2012. Patients were placed in one of these 3 groups, based on the date of their pathologic diagnosis. Data were analyzed by SPSS 16 software. T test, chi-squared, and ANOVA tests were used for data analysis, and statistical significant level was set at < 0.05.
Results: Among 939 cases with pathologic diagnosis of primary LC, male-to-female ratio was 2.36. Mean±SD age at diagnosis was 61.47±12.01 years in males and 58.45±12.75 in females (p=0.001). Squamous cell carcinoma (SCC) was the most frequent pathologic subtype. Mean age at diagnosis and rate of smokers were unchanged during the study (p= 0.978 and 0.153, respectively). Relative frequency of leading pathologic subtypes changed in 3 intervals (p<0.001): it was increasing in adenocarcinoma and large cell carcinoma and decreasing in SCC and small cell lung cancer (SCLC). There were statistically significant differences in the mean age at diagnosis (p<0.001), rate of smokers (p<0.001), and male-to-female ratio (p=0.011) between leading pathologic subtypes.
Conclusion: Similar to universal picture, rate of adenocarcinoma in northeast of Iran was rising during recent decades, especially among younger patients, women, and nonsmokers. These trends are indicative of changes in exposures and smoking habits and reveal the need for regional studies in these contexts.

Abstract
Objective: Lung cancer is the most frequently diagnosed cancer and the most leading cause of death due to cancer worldwide. This study aimed to use censored quintile regression model to estimate the effect of potential risk factors on survival of lung cancer patients. Methods: In this study we used a dataset of a retrospective cohort study conducted in West Azerbaijan (during 2007 and 2014). Demographic variables included age, and gender and biological variables included Eastern Cooperative Oncology Group, smoking, tumor type, stage, metastasis, and treatment were investigated as risk factors of survival of lung cancer patients by using censored quintile regression. Result: The mean (± standard deviation) age of the 347 lung cancer patients was 63.48 (± 13.55) years. The survival time ranges from 11 to 91. A total of 240 (67.6%) experienced death by the end of the study. The impact of Eastern Cooperative Oncology Group (IV), smoking and treatment were significant for most of quintiles (p<0.05). Stage of cancer and metastasis are the other affective risk factors on the survival of lung cancer patients(p<0.05). It was shown that Eastern Cooperative Oncology, smoking habit and treatment were significantly associated with a shorter time-to-death progression. Conclusion: As censored quintile regression could consider time-varying effects and the interpretation of its regression coefficients are easy it could be an adequate choice for analyzing survival data.

Abstract
In Iran, a developing country in southwest Asia, an epidemiologic transition is underway from communicable to noncommunicable diseases. In Iran, cancer is the second largest group of chronic non-communicable diseases (NCDs) and the third most common cause of death following heart disease, accidents and other natural phenomena. There are some studies reporting an increasing trend in the incidence and mortality rate of a variety of cancers in Iran. Therefore, controlling and preventive interventions pertaining to cancers must be a main priority for health policy and it is recommended that the high-risk population receive earlier screening. In this review, incidence and mortality of colorectal, lung, liver, thyroid, and bladder cancers in Iran are reported.

Abstract
OBJECTIVES Investigating the survival of patients with cancer is vitally necessary for controlling the disease and for assessing treatment methods. This study aimed to compare various statistical models of survival and to determine the survival rate and its related factors among patients suffering from lung cancer. METHODS In this retrospective cohort, the cumulative survival rate, median survival time, and factors associated with the survival of lung cancer patients were estimated using Cox, Weibull, exponential, and Gompertz regression models. Kaplan-Meier tables and the log-rank test were also used to analyze the survival of patients in different subgroups. RESULTS Of 102 patients with lung cancer, 74.5% were male. During the follow-up period, 80.4% died. The incidence rate of death among patients was estimated as 3.9 (95% confidence [CI], 3.1 to 4.8) per 100 person-months. The 5-year survival rate for all patients, males, females, patients with non-small cell lung carcinoma (NSCLC), and patients with small cell lung carcinoma (SCLC) was 17%, 13%, 29%, 21%, and 0%, respectively. The median survival time for all patients, males, females, those with NSCLC, and those with SCLC was 12.7 months, 12.0 months, 16.0 months, 16.0 months, and 6.0 months, respectively. Multivariate analyses indicated that the hazard ratios (95% CIs) for male sex, age, and SCLC were 0.56 (0.33 to 0.93), 1.03 (1.01 to 1.05), and 2.91 (1.71 to 4.95), respectively. CONCLUSIONS Our results showed that the exponential model was the most precise. This model identified age, sex, and type of cancer as factors that predicted survival in patients with lung cancer.

Abstract
Lung cancer (LC) is a leading cause of cancer-related morbidity and mortality globally, and exhaled breath testing has been considered as a fast, convenient and non-invasive way to diagnose LC in its early stages. Volatile organic compounds (VOCs), as markers of LC in exhaled breath, have been widely investigated for cancer diagnosis. However, few studies have reported on the interference of benign pulmonary diseases (BPD) in the selection of VOC markers for LC. During this study, 207 samples were analyzed using thermal desorption instrumentation/gas chromatography/mass spectrometry (TD-GCMS) to detect C6-C30 VOCs, and all samples were divided into four groups: LC group, BPD group, lung disease (LD) group (including LC group and BPD group) and healthy group. To make up for the deficiency of detecting low carbon hydrocarbons (<C6), 277 samples were analyzed using solid-phase micro-extraction/gas chromatography/mass spectrometry (SPME-GCMS), divided among the four groups. VOC markers were selected by reference to the receiver operating characteristics curve. With the comparisons among the LC group, BPD group and healthy group from TD-GCMS and SPME-GCMS results, we found that exhaled VOCs are capable of discriminating LC group versus healthy group and BPD group versus healthy group with a consistency of 70%-80%. However, no VOCs can be selected with good discrimination capability between the LC group and BPD group, indicating that BPD interferes significantly in VOC marker selection for LC. To discriminate breath samples from the LD group and healthy group, 11 VOCs, including ten selected from TD-GCMS and one from SPME-GCMS, were chosen as markers for LD diagnosis. The sensitivity, specificity and overall accuracy of the diagnostic model established using ten VOCs were 80.8%, 84% and 82.7%, and those of the model established by using one VOC were 75.6%, 78.9% and 76.7%. These results validate that LD patients can be effectively discriminated and diagnosed using exhaled VOC analysis. (Clinical trial registration number: ChiCTR-DCD-15007106.).

Abstract
The present study assessed the effects of the tankyrase (TNKS) small molecule inhibitor XAV939 on the proliferation and migration of lung adenocarcinoma A549 cells and the possible underlying mechanism. To do this, the association between TNKS and the WNT/β-catenin signaling pathway in lung acinar adenocarcinoma was investigated. Immunohistochemistry was performed, which demonstrated that TNKS, β-catenin and Myc proto-oncogene protein (c-Myc) proteins are positively expressed in lung adenocarcinoma tissue; this expression was significantly higher than that in normal adjacent non-carcinoma tissues. A549 cell proliferation was inhibited in all XAV939-intervention groups examined. In the wound-healing assay, cells treated with different concentrations of XAV939 exhibited a significantly increased scratch width compared with the control group. Reverse transcription-semi-quantitative polymerase chain reaction analysis revealed that β-catenin mRNA expression was significantly decreased in A549 cells in response to different XAV939 concentrations compared with the control group. Immunofluorescence revealed that β-catenin protein, initially localized in the nucleus/cytoplasm, gradually translocated to the cytoplasm/membrane, an effect that was associated with increased drug concentration. TNKS, β-catenin and c-Myc protein expression in A549 cells treated with XAV939 was reduced compared with that in untreated cells. Therefore, abnormally high TNKS expression may promote the occurrence of lung cancer. The TNKS inhibitor XAV939 inhibited lung adenocarcinoma A549 cell proliferation and migration in vitro. The underlying mechanism by which XAV939 exerted its inhibitory effects may be associated with attenuation of the WNT signaling pathway.

Abstract
Background: Prevalence statistics are essential for cancer control in addition to incidence and mortality data. As we know, there is no published report regarding lung cancer (LC) prevalence in Iran. Herein, we provide model-based estimates of limited time LC prevalence in Iran, 2015. Materials and Methods: Incidence numbers of LC were extracted from Iranian National Cancer Registry reports for 2003–2009. Trends were analyzed by joinpoint regression, assuming a logarithmic poisson model. Incidence numbers were projected up to 2015, using linear regression models which were trained by corrected annual percentage changes. A Monte Carlo-based model was generated, and absolute survival rates, number of incident cases, and incompleteness of Iranian cancer registry for LC were included into it. Limited-time prevalence (within 1, 2–3, and 4–5 years from diagnosis) and its respective 95% uncertainty level (UL) were estimated by age, gender, and histopathological type. Results: Five-year prevalence was estimated to be 4.21 (95% UL: 3.37–5.38) per 100,000 adult person, with a male:female ratio of 2.01. Estimated number of patients within 1, 2–3, and 4–5 years from diagnosis were 1871 (1497–2392), 993 (770–1285), and 420 (322–550), respectively. Most prevalent form of LC were squamous cell carcinoma (802; 579–999) and adenocarcinoma (319; 230–389) in males and females, respectively. Conclusion: According to our results, the most plausible estimates of number of alive LC patients within initial treatment, clinical follow-up, and cure phases were 2392, 1285, and 550 cases in Iran in 2015.

Abstract
Clinicians should looking for techniques that helps to early diagnosis of cancer, because early cancer detection is critical to increase survival and cost effectiveness of treatment, and as a result decrease mortality rate. Medical images are the most important tools to provide assistance. However, medical images have some limitations for optimal detection of some neoplasias, originating either from the imaging techniques themselves, or from human visual or intellectual capacity. Image processing techniques are allowing earlier detection of abnormalities and treatment monitoring. Because the time is a very important factor in cancer treatment, especially in cancers such as the lung and breast, imaging techniques are used to accelerate diagnosis more than with other cancers. In this paper, we outline experience in use of image processing techniques for lung and breast cancer diagnosis. Looking at the experience gained will help specialists to choose the appropriate technique for optimization of diagnosis through medical imaging.

Abstract
BACKGROUND Lung cancer is a fatal malignancy with high mortality and short survival time. The aim of this study was to estimate survival rates of Iranian patients with lung cancer and its associate predictive factors. MATERIALS AND METHODS The study was conducted on 355 patients admitted to hospitals of West Azerbaijan in the year 2007. The patients were followed up by phone calls until the end of June 2014. The survival rate was estimated using the Kaplan-Meier method and log-rank test for comparison. The Cox's proportional hazard model was used to investigate the effect of various variables on patient survival time, including age, sex, Eastern Cooperative Oncology Group (ECOG) performance, smoking status, tumor type, tumor stage, treatment, metastasis, and blood hemoglobin concentration. RESULTS Of the 355 patients under study, 240 died and 115 were censored. The mean and median survival time of patients was 13 and 4.8 months, respectively. According to the results of Kaplan-Meier method, 1, 2, and 3 years survival rates were 39%, 18%, and 0.07%, respectively. Based on Cox regression analysis, the risk of death was associated with ECOG group V (1.83, 95% CI: 1 CONCLUSIONS: The survival time of the patients with lung cancer is very short. While early diagnosis may improve the life expectancy effective treatment is not available.

Abstract
BACKGROUND Transthoracic fine needle aspiration (FNA) cytology and core needle biopsy (CNB) are two commonly used approaches for the diagnosis of suspected neoplastic intrathoracic lesions. This study compared the diagnostic accuracy of FNA cytology and concurrent CNB in the evaluation of intrathoracic lesions. MATERIALS AND METHODS We studied FNA cytology and concurrent CNB specimens of 127 patients retrospectively, using hematoxylin and eosin (H and E), immunohistochemistry, and, on certain occasions cytochemistry. Information regarding additional tissue tests was derived from the electronic archives of the Department of Pathology and Laboratory Medicine as well as patient records. Diagnostic accuracy was calculated for each test. RESULTS Of 127 cases, 22 were inconclusive and excluded from the study. The remaining 105 were categorized into 73 (69.5%) malignant lesions and 32 (30.5%) benign lesions. FNA and CNB findings were in complete agreement in 63 cases (60%). The accuracy and confidence intervals (CIs) of FNA and CNB for malignant tumors were 86.3% (CI: 79.3-90.7) and 93.2% (CI: 87.3- 96.0 ) respectively. For epithelial malignant neoplasms, a definitive diagnosis was made in 44.8% of cases by FNA and 80.6% by CNB. The diagnostic accuracy of CNB for nonepithelial malignant neoplasms was 83.3% compared with 50% for FNA. Of the 32 benign cases, we made specific diagnoses in 16 with diagnostic accuracy of 81.3% and 6.3% for CNB and FNA, respectively. CONCLUSIONS Our findings suggest that FNA is comparable to CNB in the diagnosis of malignant epithelial lesions whereas diagnostic accuracy of CNB for nonepithlial malignant neoplasms is superior to that for FNA. Further, for histological typing of tumors and examining tumor origin, immunohistochemical work up plays an important role.

Abstract
BACKGROUND Cancer is a major cause of mortality in developing countries and correct and valid information about the epidemiology of this disease is the first step in the planning of health care in each region. The aim of this study was to determine the relative frequency, mean age and sex ratio of the most 10 common non-skin cancers in the world and Iran, among patients referred to an oncology clinic. MATERIALS AND METHODS This descriptive study was conducted in Mashhad, north east of Iran. The data obtained from the records of patients referred to the private oncology center between the years of 1985-2012." According to the latest report of GLOBOCAN study commonest malignancies included were lung, breast, colorectal, prostate, stomach, liver, cervix, esophageal, bladder cancers and Non-Hodgkin lymphoma. RESULTS A total of 4,606 cases were analyzed. The mean age was 55.5±13.8years (male: 59.5±13.9, female: 52.6±12.9). Overall, breast cancer (1,264 cases, relative frequency of 27.4%) was the most prevalent cancer; however the mean ages of diagnosis were not significantly different between 5-year time period divisions (p=0.290). The most common cancer in men was esophageal cancer (26.3%).The lowest mean age was related to women diagnosed with breast cancer (48.5±11.8) and men with non-Hodgkins lymphoma (48.4±17.8). There were statistically significant differences between the mean age of men and women with gastric (p=0.003) and esophageal cancers (p<0.001). Male to female sex ratios in our study for bladder, lung and stomach cancers were 6.57, 2.60 and 2.50 respectively. CONCLUSIONS The results showed that breast cancer tends to be found in younger female patients and bladder cancer appears more often in men. Screening in target population in addition to early diagnosis may reduce death and disability.

Abstract
The aims of this study were to investigate the influence of ubiquitin- conjugating enzyme E2C (UBE2C) on biological behavior of lung cancer cells. Using MTT, flow cytometry and invasion assays, we detected UBE2C expression and evaluated its biological properties in these cells, including effects on proliferation, the cell cycle profile and invasive capability. Compared with control cells, the UBE2C transfected cells demonstrated increased cellular proliferation (p<0.05). UBE2C transfected cells also had a lower percentage in G1 phase and a higher percentage in S phase (p<0.05). Importantly, the UBE2C transfected cells had a notable enhancement of cell numbers penetrating the basement membrane compared with the control group (p<0.05). Ectopic up- regulation UBE2C promoted the growth of lung cancer cells in vivo. Furthermore, we found UBE2C increased the expression of cyclin D1 and MMP-2. These results show UBE2C may represent a potential therapeutic target for lung cancer.

Abstract
BACKGROUND Lung cancer is one of the most commonly diagnosed cancers and the most frequent cause of cancer-related death worldwide. In Iran, it ranks second and third as the cancer-causing death in men and women, respectively. We carried out this study to find out the demographic, clinical, and histological characteristics and risk factors of lung cancer in a referral tertiary center in Iran. MATERIALS AND METHODS A retrospective study was conducted on cases of primary lung cancer based on the results of registered cancer reports of cytological and pathological specimens between March 2001 and March 2012. Demographic variables, clinical manifestations, histology and location of tumors were determined based on the data found in the medical records of each patient. Definite or probable etiologic factors were identified. Data analysis was performed with SPSS version 16 and a p-value ≤ 0.05 was considered as significant. RESULTS A total of 203 patients, with a mean age of 65.7 years (SD=11.2), with primary lung cancer were identified, 81.3% being men. Of the total, 110 cases (54.2%) were living in urban areas. In 53.2% of cases, the site of tumor was on the right side and in 72.9% of cases the lesion was centrally located. The histological types of lung cancer were squamous cell carcinoma (SCC) in 107 cases (52.7%), adenocarcinoma (AC) in 30 cases (14.8%), and small cell carcinoma (SC) in 27 cases (13.3%). Significant correlations between the gender and residence, smoking, and the histological type and location (central or peripheral) of tumor were found. The percentage of smokers was 75.2% in men and 15.8% in women. CONCLUSIONS Smoking was the most important risk factor and squamous cell carcinoma the most common histological type of lung cancer in our study. Male sex and being a smoker was associated with histological types of SCC while being nonsmoker had relationship with adenocarcinoma.

Abstract
BACKGROUND Evidence shows direct link of HER2 to increased glycolysis and over production of lactate dehydrogenase (LDH). HER2 overexpression, high LDH and low glucose pleural levels are associated with poor prognosis in lung cancer. Here, their relationships were investigated. MATERIALS AND METHODS HER2 positivity was studied using immunohistochemistry in non-small cell lung cancer. Glucose and LDH levels were measured using commercial colorimetric kits. RESULTS Of 42 patients (29 adenocarcinoma and 13 squamous cell carcinoma), 28 (66.7%) were HER2-negative, 14 (33.3%) were HER2- positive, including 9 (21.4%) weakly stained (1+) and 5 (11.9%) moderately stained (2+) samples. The relationship between HER2 and glucose and LDH levels were tested in 20 newly diagnosed lung cancer patients who had simultaneous pleural and serum samples. Pleural and serum LDH levels were increased, and pleural glucose levels were decreased with the scale of HER2 positivity, and that the difference in glucose levels between HER2-negative group and HER2- positive patients scored at 2+ reached statistical significance (p=0.02). This latter group all had pleural glucose levels below 40 mg/dl. CONCLUSIONS For the first time, we showed a significant association between low pleural glucose level and overexpression of HER2 in lung cancer. Further investigations are warranted to disclose the association of HER2 with low pleural glucose levels in other populations, with a larger sample size, in malignant pleural effusions caused by other types of cancer, and finally to assess employment as a screening tool for finding HER2-positive cases of lung cancer.
