INTRODUCTION: Proton pump inhibitors (PPIs) are potent inhibitors of gastric acid secretion and can affect the optimal absorption of concomitant oral medications, such as vascular endothelial growth factor (VEGF) tyrosine kinase inhibitors (TKIs). The purpose of this study was to investigate the effect of PPI use on survival in metastatic renal cell carcinoma (mRCC) patients treated in the targeted therapy era. MATERIALS AND METHODS: We conducted a pooled analysis of mRCC patients treated in phase II and III clinical trials...

Changes in pH can alter the uptake of chemotherapy drugs. Proton pump inhibitors (PPIs) may therefore increase the chemosensitivity of cancer cells and cytotoxicity of chemotherapeutic drugs by increasing their uptake. We investigated the chemosensitizing potential of PPIs in colorectal cancer (CRC). Our in vitro data show that the PPI pantoprazole increases the chemosensitivity of CRC HT29 and RKO cells to fluorouracil (5-FU). Our in vivo data demonstrate that pantoprazole also increases the ability of 5-FU to inhibit CRC tumor growth in mice...

We have updated both the American College of Gastroenterology (ACG) and the Canadian Association of Gastroenterology (CAG) guidelines on dyspepsia in a joint ACG/CAG dyspepsia guideline. We suggest that patients ≥60 years of age presenting with dyspepsia are investigated with upper gastrointestinal endoscopy to exclude organic pathology. This is a conditional recommendation and patients at higher risk of malignancy (such as spending their childhood in a high risk gastric cancer country or having a positive family history) could be offered an endoscopy at a younger age...

Colorectal cancer (CRC), gastroesophageal reflux disease (GERD), inflammatory bowel disease (IBD), and nonalcoholic fatty liver disease are considered important emerging diseases in the Asia Pacific (AP) region. The incidence rate of CRC is the highest among gastrointestinal cancers in the region surpassing that of gastric cancer. However, population CRC screening is limited by availability of adequate health resources and financing. GERD is a highly prevalent disease in AP with the prevalence of GERD symptoms and reflux esophagitis reported to be increasing...

INTRODUCTION: In this study, we investigated the degree of drug interactions between gefitinib and gastric acid suppressants (ie, histamine 2-receptor antagonists [H2RAs] or proton pump inhibitors [PPIs]) with a clinical standard dose in Japanese patients with non-small-cell lung cancer. METHODS: Retrospectively, 47 patients were divided into 3 groups: gefitinib therapy with a PPI (15 patients) or an H2RA (8 patients) or gefitinib therapy alone (24 patients). On day 15 after beginning gefitinib therapy (administration at 08:00) with or without H2RA (administration twice daily at 08:00 and 18:30) or PPI (administration once daily at 08:00 or 18:30), whole blood samples were collected just prior to and at 1, 2, 4, 6, 8, 12, and 24 hours after administration...

Gastric cancer is the third leading cause of cancer-related mortality worldwide. Despite progress in understanding its development, challenges with treatment remain. Gastrin, a peptide hormone, is trophic for normal gastrointestinal epithelium. Gastrin also has been shown to play an important role in the stimulation of growth of several gastrointestinal cancers including gastric cancer. We sought to review the role of gastrin and its pathway in gastric cancer and its potential as a therapeutic target in the management of gastric cancer...

Helicobacter pylori (H. pylori) is a common gastrointestinal bacterial strain closely associated with the incidence of chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. A current research and clinical challenge is the increased rate of antibiotic resistance in H. pylori, which has led to a decreased H. pylori eradication rate. In this article, we review recent H. pylori infection and reinfection rates and H. pylori resistance to antibiotics, and we discuss the pertinent treatments...

Bone pain is one of the most common and life-limiting complications of cancer metastasis to bone. Although the mechanism of bone pain still remains poorly understood, bone pain is evoked as a consequence of sensitization and excitation of sensory nerves (SNs) innervating bone by noxious stimuli produced in the microenvironment of bone metastases. We showed that bone is innervated by calcitonin gene-related protein (CGRP)(+) SNs extending from dorsal root ganglia (DRG), the cell body of SNs, in mice. Mice intratibially injected with Lewis lung cancer (LLC) cells showed progressive bone pain evaluated by mechanical allodynia and flinching with increased CGRP(+) SNs in bone and augmented SN excitation in DRG as indicated by elevated numbers of pERK- and pCREB-immunoreactive neurons...

BACKGROUND AND AIM: It is clinically important to diagnose drug-induced gastric lesions correctly. Recently, the use of proton pump inhibitors (PPI) has increased worldwide. The histological features induced by PPI have been reported; however, few reports have described endoscopic findings induced by PPI. Therefore, we aimed to clarify the characteristic endoscopic features in PPI users and associated pathogenic factors. METHODS: We prospectively registered 1007 consecutive participants (70 PPI users and 937 nonusers) who underwent endoscopic examination for cancer screening in three hospitals/clinics...

Management of constipation in patients receiving cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) or CHOP-like chemotherapy regimens is important for prevention of paralytic ileus. We reported earlier that the laxative action of magnesium oxide is reversed by the concomitant use of antacids in cancer patients receiving opioid analgesics. Here, we assessed the prevalence of prophylactic laxative medication for the control of constipation in patients receiving CHOP or CHOP-like regimens for non-Hodgkin's lymphoma...

Proton pump inhibitors (PPIs) are known as a class of pharmaceutical agents that target H(+)/K(+)-ATPase, which is located in gastric parietal cells. PPIs are widely used in the treatment of gastric acid-related diseases including peptic ulcer disease, erosive esophagitis and gastroesophageal reflux disease, and so on. These drugs present an excellent safety profile and have become one of the most commonly prescribed drugs in primary and specialty care. Except for gastric acid-related diseases, PPIs can also be used in the treatment of Helicobacter pylori infection, viral infections, respiratory system diseases, cancer and so on...

PURPOSE: The impact of proton pump inhibitors (PPIs) on the pharmacokinetics (PK) and efficacy of ceritinib was evaluated. METHODS: A healthy subject drug-drug interaction (DDI) study was conducted to assess the effect of esomeprazole on the PK of a single 750 mg dose of ceritinib. To further investigate the impact of PPIs on the PK and efficacy of ceritinib in ALK-positive cancer patients, two subgroup analyses were performed. Analysis 1 evaluated ceritinib steady-state trough concentration (Ctrough,ss) and overall response rate (ORR) by concomitant use of PPIs in patients from the ASCEND-1, -2, and -3 studies; analysis 2 evaluated ceritinib single-dose and steady-state AUC0-24h and C max by concomitant PPI use in patients from ASCEND-1 using a definition of PPI usage similar to that used in the healthy subject study...

T-cell-originated protein kinase (TOPK) is highly and frequently expressed in various cancer tissues and plays an indispensable role in the mitosis of cancer cells, and therefore, it is an important target for drug treatment of tumor. Ilaprazole was identified to be a potent TOPK inhibitor. The data indicated that ilaprazole inhibited TOPK activities with high affinity and selectivity. In vitro studies showed that ilaprazole inhibited TOPK activities in HCT116, ES-2, A549, SW1990 cancer cells. Moreover, knockdown of TOPK in these cells decreased their sensitivities to ilaprazole...

BACKGROUND: Autophagy is a survival mechanism that allows recycling of cellular breakdown products, particularly in stressed cells. Here we evaluate the hypotheses that up-regulation of autophagy is a common mechanism of resistance to chemotherapy, and that drug resistance can be reversed by inhibiting autophagy with a proton pump inhibitor. METHODS: We exposed human PC3, LNCaP and MCF7 cells to seven clinically-used chemotherapy drugs ± pantoprazole, examined the up-regulation of autophagy and the effect on cellular proliferation by Western Blots, MTS assay and colony-forming assay...
