Colorectal cancer is a common malignancy with a high prevalence and associated mortality rate. However, the preclinical tools currently used for drug development are insufficient. The aim of the present study was to establish and characterize a specific patient-derived colon cancer xenograft (PDCCX) mouse model for drug testing. Primary colon tumors were obtained from 10 patients by surgical resection, and tumor tissues were subsequently grafted into nude mice followed by consecutive passages. Primary tumors and xenograft tumors were collected and processed for DNA sequencing, histological evaluation and immunohistochemical staining...

Inhibition of cathespsin S not only inhibits invasion and angiogenesis, but also induces apoptosis and autophagy in cancer cells. In present study, we revealed that pharmacological inhibitor [Z-FL-COCHO (ZFL)] of cathepsin S up-regulates pro-apoptotic protein Bim expression at the posttranslational levels. These effects were not associated with MAPKs and AMPK signal pathways. Interestingly, pretreatment with the chemical chaperones (TUDCA and PBA) and knockdown of protein phosphatase 2A (PP2A) markedly inhibited ZFL-induced Bim upregulation...

Human pancreatic ductal adenocarcinoma (PDAC) contains a distinctively dense stroma that limits the accessibility of anticancer drugs, contributing to its poor overall prognosis. Nanoparticles can enhance drug delivery and retention in pancreatic tumors and have been utilized clinically for their treatment. In preclinical investigations, various mouse models differentially recapitulate the microenvironmental features of human PDAC. Here, we demonstrate that through utilization of different organic co-solvents and by doping of a homopolymer of poly(ε-caprolactone), a diblock copolymer composition of poly(ethylene oxide)- block-poly(ε-caprolactone) may be utilized to generate biodegradable and nanoscale micelles with different physical properties...

Chemotherapy-induced neutropenia (CIN) has been shown to be associated with improved clinical outcomes in patients with various solid tumors. This study retrospectively assessed the association between timing of CIN and prognosis in 321 patients with advanced gastric cancer (AGC) who finished at least one cycle of chemotherapy with oxaliplatin and capecitabine (XELOX). Primary landmark analyses were restricted to 274 patients who received four cycles of chemotherapy and lived for more than 4 months. CIN was categorized as early-onset and non-early-onset...

BACKGROUND: Many factors, including histopathologic parameters, seem to influence the prognosis of patients undergoing resection of colorectal cancer liver metastases (CRCLM), although their relative weight is unclear. Histopathologic growth patterns (HGPs) of CRCLM may affect sensitivity to antiangiogenics. We aimed at evaluating differences in histopathologic parameters of response according to the use of bevacizumab or cetuximab as first-line targeted agents, and at exploring the prognostic and predictive role of HGPs...

The candidate vitamin ergothioneine (ET) is a unique antioxidant. Expression of the ergothioneine transporter (ETT) (gene symbol SLC22A4) in distinct cells is thought to signal intracellular ET activity, since we have previously shown that the ETT is highly selective for ET. Unfortunately, some continue to hold the ETT as a relevant drug transporter, using the misleading functional name OCTN1, novel organic cation transporter. The present study was provoked by 2 recent reports in which new ETT substrates were declared...

Oxaliplatin-induced peripheral neuropathy (OIPN) is a severe, dose-limiting toxicity associated with cancer chemotherapy. The efficacy of antioxidant administration in OIPN is debatable, as the promising preliminary results obtained with a number of antioxidants have not been confirmed in larger clinical trials. Besides its antioxidant activity, the transcription factor, nuclear factor-erythroid 2 (NF-E2) p45-related factor 2 (Nrf2) plays a crucial role in the maintenance of mitochondrial homeostasis, and mitochondrial dysfunction is a key contributor to OIPN...

BACKGROUND: FOLFOXIRI (Fluorouracil, folinate, oxaliplatin, and irinotecan) plus bevacizumab improved progression-free survival (PFS) and overall survival in patients with metastatic colorectal cancer (mCRC), compared with FOLFIRI (fluorouracil, folinate, and irinotecan) plus bevacizumab, but significantly increased the incidences of adverse events. The efficacy and safety profiles of FOLFOXIRI plus bevacizumab in ethnic Asian patients have not been established yet. PATIENTS AND METHODS: This study was an open-label, single-arm, multi-centered phase II prospective clinical trial in patients with mCRC who received FOLFOXIRI plus bevacizumab...

Introduction: In Japan, the age of patients with pancreatic cancer has increased. Combination chemotherapies such as 5-fluorouracil/leucovorin, oxaliplatin and irinotecan therapy and gemcitabine hydrochloride (GEM) +nab paclitaxel therapy have been developed as the standard treatments for young patients with advanced recurrent pancreatic cancer. However, both therapies produce toxicity and their administration is limited by the patients' age or performance status. The efficacy and safety data obtained in the GEST study-a large-scale randomised controlled study conducted in patients with pancreatic cancer in Japan-suggested that GEM +S-1 (GS) combination therapy is a promising candidate for those aged between 75 and 80 years...

BACKGROUND: The efficacy of oxaliplatin-based chemotherapy combined with anti-epidermal growth factor receptor (EGFR) monoclonal antibody (mAb) remains controversial in metastatic colorectal cancer (mCRC). This meta-analysis aims to estimate the effect of adding panitumumab or cetuximab to oxaliplatin-based chemotherapy in RAS wild type mCRC patients for the first-line treatment. The primary tumor location is also considered into this meta-analysis. METHODS: RCT studies were identified by a search of MEDLINE, EMBASE, Cochrane library to October 2017, supplemented by manually retrieving ASCO, ESMO conference abstracts...

Chemotherapy is considered "state of the art" for the treatment of poorly differentiated neuroendocrine neoplasms. Unfortunately, there is no standard effective post-first-line treatment for relapsing high-grade gastroenteropancreatic neuroendocrine neoplasms. We report the case of a patient with a gastric neuroendocrine carcinoma stage IV, with massive gastrointestinal bleeding at diagnosis. After the first line of platin-based chemotherapy a major tumoral response was documented, but the patient relapsed after 4 months...

While gemcitabine has been the mainstay therapy for advanced pancreatic cancer, newer combination regimens (e.g. FOLFIRINOX) have extended patient survival, though carry greater toxicity. Biomarkers are needed to better stratify patients for appropriate therapy. Previously, we reported that one-third of pancreatic cancers harbor deletions or deleterious mutations in key subunits of the SWItch/Sucrose NonFermentable (SWI/SNF) chromatin remodeling complex. The SWI/SNF complex mobilizes nucleosomes on DNA, and plays a key role in modulating DNA transcription and repair...

The clinical applications of platinum-based antitumor agents are still largely limited by severe side effects as well as multidrug resistance (MDR). To solve these problems, we developed an 1,2-diaminocyclohexane-platinum(II) (DACHPt)-loaded nanoparticle (NP-TPGS-Pt) by self-assembly of poly(amidoamine)-polyglutamic acid- b -D-α-tocopheryl polyethylene glycol 1000 succinate (PAM-PGlu- b -TPGS) and DACHPt. NP-TPGS-Pt showed robust stability and pH-responsive DACHPt release profile in vitro similar to the PEG-containing nanoparticle (NP-PEG-Pt)...

Background: Recently, therapeutic strategies for a metastasectomy from colorectal carcinoma after chemo-targeted therapy with bevacizumab have been presented, with which some uncommon but serious adverse events have been reported. However, only few reports have investigated the safety of lung resection after such therapy or the histological effects. We retrospectively analyzed the both of them at our institute. Methods: Of 69 colorectal carcinoma patients who underwent pulmonary metastasectomy procedures from 2009 to 2014, we investigated 11 who also received chemo-targeted therapy prior to surgery...

The prognostic significance of glandular differentiation in urothelial carcinoma (UC) is controversial, and thus far there is no established treatment strategy against metastasis of glandular component. We describe here a case of metastatic UC with glandular differentiation that had histological disappearance of adenocarcinoma components at autopsy after sequential chemotherapy with S-1 and cisplatin (CDDP) and with mFOLFOX6 (fluorouracil, oxaliplatin, and leucovorin) plus bevacizumab (mFOLFOX6+Bev). A 62-year-old Asian male was diagnosed with invasive UC with glandular differentiation (T2N0M0) by radical cystectomy and ileal conduit, and careful follow-up observation was made...

PURPOSE: Fluorouracil monotherapy, instead of the FOLFOX or FOLFIRI regimen, is administered to patients intolerant to oxaliplatin or irinotecan because of their adverse effects. A prospective clinical trial was designed to evaluate the efficacy and safety of fluorouracil monotherapy combined with panitumumab administered to patients with KRAS wild-type (WT) metastatic colorectal cancer (mCRC) intolerant to oxaliplatin and irinotecan. Screening for potential serum biomarkers to predict early therapeutic responses was conducted...

Chemotherapy remains the mainstay of treatment for advanced pancreatic ductal adenocarcinoma (pda). Two randomized trials have demonstrated superiority of the combination regimens folfirinox (5-fluorouracil, leucovorin, oxaliplatin, and irinotecan) and gemcitabine plus nab-paclitaxel over gemcitabine monotherapy as a first-line treatment in adequately fit subjects. Selected pda patients progressing to first-line therapy can receive secondline treatment with moderate clinical benefit. Nevertheless, the optimal algorithm and the role of combination therapy in second-line are still unclear...
