BACKGROUND: Histological classification of lung cancer is essential for investigations of carcinogenesis and treatment selection. We examined the temporal changes of lung cancer histological subtypes. METHODS: Lung cancer cases diagnosed in the Life Span Study cohort between 1958 and 1999 were collected from tumor registries (TR), mainly consisting of population-based cancer registries. A total of 1,025 cases were histologically reviewed according to the World Health Organization 2004 Classification by a panel of pathologists (PP)...

BACKGROUND: Resistance to chemotherapy drugs (e.g. taxol) has been a major obstacle in successful cancer treatment. In A549 human lung adenocarcinoma, acquired resistance to the first-line chemotherapy taxol has been a critical problem in clinics. Sphingolipid (SPL) controls various aspects of cell growth, survival, adhesion, and motility in cancer, and has been gradually regarded as a key factor in drug resistance. To better understand the taxol-resistant mechanism, a comprehensive sphingolipidomic approach was carried out to investigate the sphingolipid metabolism in taxol-resistant strain of A549 cell (A549T)...

A late-relapse germ cell tumor might contain malignant non-germ cell tumors, known as 'somatic-type malignancy (SM)'. The development of a secondary SM is rare, and this phenomenon remains poorly understood. Case 1 developed lung metastasis 13 years after chemotherapy followed by retroperitoneal lymph node dissection for stage IIA non-seminoma. The tumor increased in size after chemotherapy. The patient underwent a pneumonectomy. Pathology revealed an adenocarcinoma with immature teratoma. The patient has experienced no relapse for 9 years...

BACKGROUND: Despite high-quality evidence demonstrating that screening reduces mortality from breast, cervical, colorectal, and lung cancers, a substantial portion of the population remains inadequately screened. There is a critical need to identify interventions that increase the uptake and adoption of evidence-based screening guidelines for preventable cancers at the community practice level. Text messaging (short message service, SMS) has been effective in promoting behavioral change in various clinical settings, but the overall impact and reach of text messaging interventions on cancer screening are unknown...

PURPOSE: Despite, vaccination is a highly effective and widely recommended for prevention of certain infections, vaccination coverage is very low. The purposes of this study were to evaluate the attitudes of medical oncologists towards vaccination and to identify predictors of intention to recommend vaccination in patients with cancer. METHODS: A structured questionnaire is formed to evaluate the daily practice of vaccination. Turkish medical oncologists were invited to this study via email, SMS, or phone call...

BACKGROUND: The cytological analysis of peritoneal effusions serves as a diagnostic and prognostic aid for either primary or metastatic diseases. Among the different cytological preparations, liquid based cytology (LBC) represents a feasible and reliable method ensuring also the application of ancillary techniques (i.e immunocytochemistry-ICC and molecular testing). METHODS: We recorded 10348 LBC peritoneal effusions between January 2000 and December 2014. They were classified as non-diagnostic (ND), negative for malignancy-NM, atypical-suspicious for malignancy-SM and positive for malignancy-PM...

INTRODUCTION: Management of lung cancer remains a challenge. Although clinical and biological patient data are crucial for cancer research, these data may be missing from registries and clinical trials. Biobanks provide a source of high-quality biological material for clinical research; however, linking these samples to the corresponding patient and clinical data is technically challenging. We describe the mobile Lung Cancer Care system (mLCCare), a novel tool which integrates biological and clinical patient data into a single resource...

Matrix assisted laser desorption ionization (MALDI)-time of flight/mass spectrometry (TOF/MS) was applied to investigate alterations in phospholipids in mitophagic cancer cells. Several phospholipids, including phosphatidylcholines (PCs), sphingomyelins (SMs), and phosphatidylinositols (PIs), were successfully analyzed in control and mitophagy-induced H460 cells in the positive and negative ion modes. Principal component analysis was applied to differentiate the two groups. The upregulated and downregulated phospholipid species in the mitophagic cells were also represented in a heatmap...

Lung cancer is the leading cause of cancer deaths worldwide. Targeting complementary pathways will achieve better treatment efficacy than a single agent high-dose strategy that could increase risk of side effects and tumor resistance. To target COX-2, 5-LOX, and ODC simultaneously, we tested the effects of a dual 5-LOX-COX inhibitor, licofelone, and an ODC inhibitor, DFMO, alone and in combination, on NNK-induced lung tumors in female A/J mice. Seven-week-old mice were treated with NNK (10 μmol/mouse, single dose, i...

INTRODUCTION: This research aims to optimize and predict the effectiveness of imatinib mesylate (imatinib) in tumors expressing platelet-derived growth factors (PDGF-AA, BB), kit/stem cell factor (SCF) ligands and their respective receptors (PDGFR-α, PDGFR-β, and c-kit). MATERIAL AND METHODS: Samples of normal primary human T cells were incubated with graded concentrations of 1-5 μM imatinib. The energy yield by imatinib doses in those samples was identified in H-thymidine proliferation assay as described before in earlier studies...

Non-small cell lung cancer (NSCLC) is the leading cause of cancer death globally. To develop better diagnostics and more effective treatments, research in the past decades has focused on identification of molecular changes in the genome, transcriptome, proteome, and more recently also the metabolome. Phospholipids, which nevertheless play a central role in cell functioning, remain poorly explored. Here, using a mass spectrometry (MS)-based phospholipidomics approach, we profiled 179 phospholipid species in malignant and matched non-malignant lung tissue of 162 NSCLC patients (73 in a discovery cohort and 89 in a validation cohort)...

BACKGROUND: Waldenström macroglobulinemia (WM) is an indolent malignancy that predominantly affects older individuals who are at risk for secondary malignancies (SMs). The objective of this study was to characterize the incidence of SMs after a diagnosis of WM with the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: With SEER-13 data (1992-2011), standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated for the rates of solid and hematologic SMs in WM patients versus the general population...

Traditionally, nicotine from second hand smoke (SHS), active or passive, has been considered the most prevalent substance of abuse used during pregnancy in industrialized countries. Exposure to environmental tobacco smoke (ETS) is associated with a variety of health effects, including lung cancer and cardiovascular diseases. Tobacco is also a major burden to people who do not smoke. As developing individuals, newborns and children are particularly vulnerable to the negative effects of SHS. In particular, prenatal ETS has adverse consequences during the entire childhood causing an increased risk of abortion, low birth weight, prematurity and/or nicotine withdrawal syndrome...

Human tumor xenografts in immunodeficient mice are a very popular model to study the development of cancer and to test new drug candidates. Among the parameters analyzed are the variations in the lipid composition, as they are good indicators of changes in the cellular metabolism. Here, we present a study on the distribution of lipids in xenografts of NCI-H1975 human lung cancer cells, using MALDI imaging mass spectrometry and UHPLC-ESI-QTOF. The identification of lipids directly from the tissue by MALDI was aided by the comparison with identification using ESI ionization in lipid extracts from the same xenografts...

BACKGROUND: It is unclear whether endoscopic mediastinal lymph node (LN) staging techniques are equivalent to surgical mediastinal staging (SMS) techniques in patients with potentially operable non-small cell lung cancer (NSCLC). METHODS: A total of 166 patients with confirmed or suspected NSCLC who required SMS based on current guidelines were enrolled in this prospective controlled trial comparing endosonographic mediastinal LN staging with SMS. Each patient served as his or her own control...

Neuroblastoma, a cancer of the sympathetic nervous system, is the most common extracranial solid tumor in children. MYCN amplification and increased BDNF/TrkB signaling are features of high-risk tumors; yet, only ˜25% of malignant tumors display these features. Thus, the identification of additional biomarkers and therapeutic targets is essential. As aminoacylase 1 (ACY1), an amino acid deacetylase, is a putative tumor suppressor in small cell lung and renal cell carcinomas, we investigated whether it or the other family members aspartoacylase (ASPA, aminoacylase 2) or aminoacylase 3 (ACY3) could serve a similar function in neuroblastoma...

Our group has recently developed 1-(t)butyl carbamoyl, 7-methyl-indole-3-ethyl isothiocyanate (NB7M), a novel indole ethyl isothiocyanate analog. We now describe its selective cytotoxicity in both central nervous system (CNS) and neuroblastoma (NB) cancer cells. In an effort to understand its mechanism of action we examined the effects of NB7M on apoptosis, cell cycle arrest, and pro-survival/mitogen-activated protein kinase (MAPK) signaling in neuroblastoma cells. NB7M proved highly cytotoxic to NB cell lines (SMS-KCNR, SK-N- SH, SH-SY5Y, IMR-32) with IC(50) values ranging from 1...

Despite developments in diagnosis and treatment, lung cancer is the commonest cause of cancer death in Europe and North America. Due to increasing cigarette consumption, the incidence of the disease and resultant mortality is rising dramatically in women. Novel approaches to the management of lung cancer are urgently required. Somatostatin is a tetradecapeptide first identified in the pituitary and subsequently throughout the body particularly in neuroendocrine cells of the pancreas and gastrointestinal tract and the nervous system...

Somatostatin and its analogs are antiproliferative in a wide range of normal and neoplastic tissues. In this study we investigated the effect of octreotide (SMS 201-995) on the invasion and growth of three follicular thyroid cancer (FTC) cell lines from one patient in vitro and in vivo. FTC133 was established from the primary tumor, FTC236 from a cervical lymph node metastasis, and FTC238 from a lung metastasis. Invasion was the ability of tumor cells to penetrate 8-microns pore polycarbonate membranes coated with Matrigel...

To further investigate the antineoplastic efficacy and safety of somatostatin analogues, 2 trials were performed. Octreotide, SMS 201-995 (Sandostatin), was escalated in doses ranging from 1,500 micrograms to 6,000 micrograms daily in 14 patients with carcinoid. Somatuline, (BIM 23014C, Angiopeptin, Lanreotide) was given in doses ranging from 2,250 micrograms to 9,000 micrograms daily to 13 neuroendocrine patients (6 carcinoid, 2 atypical carcinoid, 3 pancreatic islet cell and 2 small cell lung cancer patients)...
