BACKGROUND: Currently, no large study addressing the relationship between lung cancer patients with different therapies and second primary malignancies (SPMs) is available. METHODS: Using the Taiwan National Health Insurance Research Database, we conducted a population-based cohort study. Patients with newly diagnosed lung cancer between 1997 and 2005 were enrolled and followed up until Dec. 31, 2011. The endpoint of the study was SPM occurrence. Standardized incidence ratios (SIRs) of cancers were calculated to compare the cancer incidence of the study cohort to that of the general population...

BACKGROUND: Spray cryotherapy (SCT) of airway lesions is used to effectively palliate respiratory symptoms related to airway obstruction, but significant intraoperative hemodynamic complications have been noted. We reviewed the experience at a single institution using SCT for the treatment of obstructive airway tumors. METHODS: A retrospective review of a single institution experience with intraoperative and postoperative hemodynamic complications associated with SCT was performed...

BACKGROUND: Advanced head and neck squamous cell carcinomas frequently develop distant metastases to limited organs, including the lungs, bone, mediastinal lymph nodes, brain, and liver. Peritoneal carcinomatosis as an initial distant metastasis from hypopharyngeal squamous cell carcinoma is quite rare. CASE PRESENTATION: A 75-year-old man diagnosed with hypopharyngeal squamous cell carcinoma and his clinical stage was determined as T2N2cM0. Notably, the right retropharyngeal lymph node surrounded more than half of the right internal carotid artery...

PURPOSE: To develop a clinically viable gene expression assay to measure RAS/RAF/MEK/ERK (RAS-ERK) pathway output suitable for hypothesis testing in non-small cell lung cancer (NSCLC) clinical studies. EXPERIMENTAL DESIGN: A published MEK-functional-activation signature (MEK signature) that measures RAS-ERK functional output was optimized for NSCLC in silico. NanoString assays were developed for the NSCLC optimized MEK signature and the 147-gene RAS signature. First, platform transfer from Affymetrix to NanoString, and signature modulation following treatment with KRAS siRNA and MEK inhibitor, were investigated in cell lines...

Synchronous occurrence of multiple lung cancers in the same lobe of the lung is very rare. Most of the tumors diagnosed in this way have the same histologic type. With imaging methods it is difficult to determine if the multiple lung lesions present hematogenous spread of lung cancer (or cancer from other origin) or these lesions present the second primary lung cancer. We report a rare and unusual case of synchronous occurrence of primary adenocarcinoma and squamous cell carcinoma in the same lobe of the lung...

The world health organization figures show prostate cancer in developed countries has been the second primary cause of cancer mortality following lung cancer for the men. So, early and sensitive diagnosis of cancer is very important before it spreads out to the other organs of the body. It is well-known that prostate-specific antigen (PSA) is the most specific and efficient tumor marker for the diagnosis of prostate cancer. Herein, we successfully fabricated core-shell composite fluorescent nanoparticle Ag@SiO2@SiO2-RuBpy which provide a photoluminescence enhancement of up to ~3-fold when the separation distance between the surface of silver core and the center of the third RuBpy doped silica shell is about 10nm...

INTRODUCTION: Pancreatic metastases are uncommon and only found in a minority of patients with widespread metastatic disease at autopsy. The most common primary cancer site resulting in pancreatic metastases is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma and sarcoma. PRESENTATION OF CASE: Herein, we report a 63-year-old male patient who presented -3.5 years after radical nephrectomy performed for renal cell carcinoma (RCC)-with a well-defined lobular, round mass at the body of the pancreas demonstrated by abdominal Magnetic Resonance Imaging (MRI)...

The first Chinese-German Lung Cancer Expert Panel was held in November 2015 one day after the 7th Chinese-German Lung Cancer Forum, Shanghai. The intention of the meeting was to discuss strategies for the diagnosis and treatment of lung cancer within the context of lung cancer screening. Improved risk classification criteria and novel imaging approaches for screening populations are highly required as more than half of lung cancer cases are false positive during the initial screening round if the National Lung Screening Trial (NLST) demographic criteria [≥30 pack years (PY) of cigarettes, age ≥55 years] are applied...

Diverse molecular mechanisms that confer acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) in lung cancers with sensitive EGFR mutations have been reported. However, it is not realistic to analyze for all these mechanisms at the time of resistance in clinical practice and establish adequate treatment targeting these numerous resistance mechanisms. Therefore, we believe that we should move our research focus from the exploration of "established" diverse resistance mechanisms to the elucidation of molecular mechanisms that enable cancer cells to remain alive at the early phase of the treatment...

BACKGROUND AND PURPOSE: Radiotherapy plays an essential role in early breast cancer treatment, but is also associated with an increased risk of second malignancies decades after the exposure. MATERIALS AND METHODS: We systematically searched the data-bases Medline/Pubmed, Cochrane, Embase, and Cinahl, for cohort studies estimating the risk of second non-breast cancer after primary breast cancer. Every included study was to report the standardized incidence ratio [SIR] of second cancers, comparing the risk among either irradiated or unirradiated female breast cancer patients to the risk of the general female population...

PURPOSE: To investigate the second primary cancers (SPCs) in patients with urothelial cancer (UC). MATERIALS AND METHODS: The records of 2,339 patients whose UC was diagnosed between January 1974 and December 2012 were reviewed. All data about characteristics of patients, of UC and, of SPC was, recorded digitally. We investigated the prevalence and the type of second or higher order cancers, and the factors associated with SPC. RESULTS: Total 260 patients (11...

BACKGROUND: Lung cancer is one of the most lethal cancers. It is mainly classified into 2 groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Extrapulmonary small cell carcinomas (EPSCC) are very rare. The Ras oncogene controls most of the cellular functions in the cell. Overall, 21.6% of human cancers contain a Kirsten Ras (KRAS) mutation. SCLC and EPSCC have several similar features but their clinical course is different. AIMS: We investigated the KRAS mutation status in SCLC and EPSCC...

The prognosis of lung carcinoma with metastasis to the bone, particularly to the spine, is poor. Chemotherapy and radiotherapy are established treatments for metastatic bone disease, but their effectiveness is unsatisfactory and bone repair following their use is slow and difficult. Medicine prepared from herbal extracts may be an alternative treatment option. The present study discusses the case of a 59-year-old patient diagnosed with squamous cell lung cancer (T2N3M1) in which first-line chemotherapy using docetaxel plus cisplatin failed...

OBJECTIVES: Controversy exists about the integration of erlotinib in patients with EGFR wildtype, advanced NSCLC. MATERIALS AND METHODS: We included patients with advanced NSCLC receiving at least two lines of palliative systemic treatment between January 2005 and December 2014 and not harbouring targetable driver mutations. Primary study endpoint was overall survival (OS), secondary endpoint progression-free survival (PFS). We used Kaplan-Meier statistics, multivariate Cox regression and Propensity score or Inverse Probability Weights (IPW) matching to compare clinical outcome between patients receiving erlotinib in second or further line and those receiving chemotherapy only...

The loss of E-cadherin expression in association with the epithelial-mesenchymal transition (EMT) occurs frequently during tumor metastasis. However, metastases often retain E-cadherin expression, an EMT is not required for metastasis, and metastases can arise from clusters of tumor cells. We demonstrate that the regulation of the adhesive activity of E-cadherin present at the cell surface by an inside-out signaling mechanism is important in cancer. First we find that the metastasis of an E-cadherin expressing mammary cell line from the mammary gland to the lung depends on reduced E-cadherin adhesive function...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and usually occur in the stomach and the small intestine. The pancreas is an extremely rare primary site for GISTs and there are 25 reported cases of pancreatic GIST with most being treated with surgical resection. We describe a 52-year-old African-American female who was diagnosed with limited stage small cell carcinoma in November 2009 and treated with concurrent cisplatin/etoposide chemotherapy and radiation...

Patients who have had curative surgery for lung cancer are at the highest risk of developing a new lung cancer. Individual studies are usually underpowered to describe the clinical characteristics and outcomes in second primary lung cancer (SPLC). The goal of this study is to determine which treatment is best associated with survival in patients who develop a new primary lung cancer. All pathologically proven stage I lung cancer cases that received cancer-directed surgery included in the Surveillance Epidemiology and End Results database between 2004 and 2010 were selected...
