We report a 72-year-old woman who was initially diagnosed with locally advanced gastric cancer with involvement of the esophagus and pancreas. She received 3 courses of neoadjuvant chemotherapy(NAC)with docetaxel, cisplatin, and 5- fluorouracil(the DCF regimen)and achieved an excellent response. She underwent total gastrectomy with distal pancreatectomy, splenectomy, and D2 lymphadenectomy. Histological examination confirmed a pathological complete response. NAC chemotherapy can down stage/down size the disease and allow some patients to undergo curative radical surgery...

BACKGROUND: Increasing numbers of patients are treated by robotic distal gastrectomy (RDG); however, it remains unclear whether RDG is clinically comparable with conventional laparoscopic distal gastrectomy (LDG). This study aimed to clarify the feasibility of RDG from safety aspects. METHODS: The study included 109 cT1 gastric cancer patients who underwent RDG at Shizuoka Cancer Center from January 2012 to April 2015. Short-term outcomes were compared with 160 cT1 gastric cancer patients who underwent LDG during the same period...

Activin Receptor-Like Kinase 5 (ALK-5) is related to some types of cancer, such as breast, lung and pancreas. In this study, we have used molecular docking, molecular dynamics simulations and free energy calculations in order to explore key interactions between ALK-5 and six bioactive ligands with different ranges of biological activity. The motivation of this work is the lack of crystal structure for inhibitor-protein complexes for this set of ligands. The understanding of the molecular structure and the protein-ligand interaction could give support for the development of new drugs against cancer...

BACKGROUND: The improving efficacy of cancer treatment has resulted in an increasing array of treatment-related symptoms and associated burdens imposed on individuals undergoing aggressive treatment of their disease. Often, clinical trials compare therapies that have different types, and severities, of adverse effects. Whether rated by clinicians or patients themselves, it can be difficult to know which side effect profile is more disruptive or bothersome to patients. A simple summary index of bother can help to adjudicate the variability in adverse effects across treatments being compared with each other...

Preclinical studies have attributed 3,3',5-triiodo-L-thyronine (T3) a direct negative effect on tumor progression, as well as chemosensitizing, differentiating and immunomodulatory properties. On the other hand, L-thyroxine (T4), via a thyroid hormone receptor on plasma membrane integrin αvβ3, promotes solid tumor growth and neoangiogenesis, therefore lowering endogenous T4 reduces tumor growth rate. We present the case of two patients with metastatic triple negative breast cancer and metastatic pancreatic cancer respectively, who benefit of the sole treatment with antithyroid drugs and exogenous administration of T3 (liothyronine)...

Background and study aims:  Pancreatic intraductal papillary mucinous neoplasms (IPMN) are cystic tumors of the pancreas characterized by a malignant potential. IPMN have been associated with recurrent pancreatitis (RP). Obstruction of the main pancreatic duct by thick mucus has been postulated to be the cause of pancreatitis. In a few isolated reports, pancreatic sphincterotomy (PS) has been reported to reduce the frequency of pancreatitis. The aim of this study was to assess the efficacy of PS in patients with IPMN-associated RP...

Pancreatic ductal adenocarcinoma (PDAC) is one of the leading forms of cancer related deaths in the United States. With limited treatment options and unreliable diagnostic methods, long-term survival rates following a diagnosis of pancreatic cancer remain poor. Pancreatic intraepithelial neoplasia (PanIN) are precancerous lesions that precede progression towards PDAC. PanIN occur in increasing complexity as the disease progresses and the description of PanIN plays a critical role in describing, staging and diagnosing PDAC...

Interest in non-coding regions of DNA has been increasing since the mapping of the human genome revealed that human DNA contains far fewer genes encoding proteins than previously expected. However, analysis of the derivatives of DNA transcription (transcriptomics) revealed that the majority of the genetic material is transcribed into non-coding RNA (ncRNA), indicating that these molecules probably provide the functional diversity and complexity of the physiology of the human body that cannot be attributed to the proteins...

The ETS family transcription factor ETV4 is aberrantly expressed in a variety of human tumors and plays an important role in carcinogenesis through upregulation of relevant target gene expression. Here, it is demonstrated that ETV4 is overexpressed in pancreatic cancer (PC) tissues as compared to the normal pancreas, and is associated with enhanced growth and rapid cell cycle progression of PC cells. ETV4 expression was silenced through stable expression of a specific short-interfering hairpin RNA (shRNA) in two PC cell lines (ASPC1 and Colo357), while it was ectopically expressed in BXPC3 cells...

ABSTRACT: HASH(0x38f7db8) CONTEXT: Pancreatic metastases from primary malignant tumors at other sites are rare, constituting about 2% of the neoplasms that affect the pancreas. Pancreatic metastasis from breast cancer is extremely rare and difficult to diagnose, because its clinical and radiological presentation is similar to that of a primary pancreatic tumor. CASE REPORT: A 64-year-old female developed a lesion in the pancreatic tail 24 months after neoadjuvant therapy, surgery and adjuvant radiation therapy for right-side breast cancer (ductal carcinoma)...

IMP3 is an RNA binding protein required for ribosomal RNA processing, which has been suggested to be a prognostic marker in a large variety of human types of cancer. However, available data on the prevalence of IMP3 expression are largely discrepant. To systematically investigate the epidemiology and clinical relevance of IMP3 expression in human cancers we employed a two-step tissue microarrays (TMAs) approach. First, a normal tissue TMA and a multi-tumor TMA were analyzed for immunohistochemically detectable expression of IMP3 in 76 different normal tissue types and 3889 cancer samples from 95 different tumor categories...

Pancreatic ductal adenocarcinoma (PDA) is one of the major types of cancer that exhibit high mortality worldwide because of the late diagnosis and the lack of effective treatment. Immunotherapy appears to be ineffective in PDA treatment due to the existence of a unique immune-suppressive microenvironment in PDA. Gemcitabine-based therapy is still the most commonly used chemotherapy to treat PDA patients with only marginal increased survival rates. This prompted us to continue the search for more effective therapy for PDA treatment...

Pancreatic cancer is a high mortality form of cancer, with a median survival only six months. There are multiple associated risk factors associated, most importantly type 2 diabetes, obesity, pancreatitis and smoking. The relative rarity of the disease, however, has made it difficult to dissect causative risk factors, especially with related risk factors. A major unanswered question with important therapeutic implications is the effect of immunological responses on pancreatic cancer formation, with data from other cancers suggesting the potential for local immunological responses to either increase cancer development or increase cancer elimination...

Comorbidities have considerable effects on survival outcomes. The primary objective of this retrospective study was to examine the association between age-adjusted Charlson comorbidity index (ACCI) score and postoperative in-hospital mortality in patients with digestive system cancer who have undergone surgical resection of their cancers. Using electronic hospitalization summary reports, we identified 315,464 patients who had undergone surgery for digestive system cancer in top-rank (Grade 3A) hospitals in China between 2013 and 2015...
