Germ cell tumors (GCTs) are extraordinarily sensitive to cisplatin (CDDP)-based chemotherapy. DNA damage represents one of the most important factors contributing to toxic effects of CDDP-based chemotherapy. This study was aimed to evaluate the prognostic value of DNA damage level in peripheral blood lymphocytes (PBLs) from chemo-naïve GCT patients. PBLs isolated from 59 chemotherapy-naïve GCT patients were included into this prospective study. DNA damage levels in PBLs were evaluated by the Comet assay and scored as percentage tail DNA by the Metafer-MetaCyte analyzing software...

Nasopharyngeal carcinoma (NPC) is highly incident in southern China. Metastasis is the major cause of death in NPC patients. Concurrent chemoradiotherapy (CCRT) has been accepted as standard in the treatment of patients with locoregionally advanced nasopharyngeal carcinoma (NPC). However, induction chemotherapy (IC) also has benefits in this disease, especially in the patients with certain high-risk factors such as bulky and/or extensive nodal disease. It has been presented that adding IC to CCRT might be a reasonable approach and need more work to confirm...

Colorectal cancer (CRC) is one of most prevalent malignant diseases worldwide. Metastasis and chemo-resistance are the two prominent death-related factors of CRCs. Thus, it is urgent to understand the mechanism responsible for the chemo-resistant properties of CRC and develop new therapeutic methods. Here, we found that the expression of miR-659-3p was significantly reduced in cisplatin (CDDP)-resistant HT29 and LOVO colorectal cancer cells and in CDDP-resistant clinical colorectal cancer samples compared with respective CDDP-sensitive counterparts...

Between September 1995 and December 2010, 99 new consecutive assessable patients with extra-cranial MGCT were treated according to SFOP/SFCE TGM95 Protocol. A "watch and wait" strategy for completely resected stage I-II was observed in cases with preoperative high tumor markers levels. Metastatic disease or alpha fetoprotein levels > 15 000 ng/ml cases were treated by VIP chemotherapy (etoposide, ifosfamide and CDDP) 4-6-courses. All other cases were treated by VBP (vinblastine, bleomycin, and CDDP) 3-5 courses...

Lung cancer has substantial mortality worldwide, and chemotherapy is a routine regimen for the treatment of patients with lung cancer, despite undesirable effects such as drug resistance and chemotoxicity. Here, given a possible antitumor effect of the fruit hull of Gleditsia sinensis (FGS), we tested whether FGS enhances the effectiveness of cis-diammine dichloridoplatinum (II) (CDDP), a chemotherapeutic drug. We found that CDDP, when administered with FGS, significantly decreased the viability and increased the apoptosis and cell cycle arrest of Lewis lung carcinoma (LLC) cells, which were associated with the increase of p21 and decreases of cyclin D1 and CDK4...

AIMS: It has been shown that exposure to extremely-low frequency (˂300Hz) oscillating electromagnetic field (EMF) can affect gene expression. The effects of different exposure patterns of 50-Hz EMF and co-treatment of EMF plus cisplatin (CDDP) on mRNA levels of seven genes involved in DNA repair pathways (GADD45A, XRCC1, XRCC4, Ku70, Ku80, DNA-PKcs and LIG4) were evaluated. MAIN METHODS: Two 50-Hz EMF intensities (0.25 and 0.50mT), three exposure patterns (5min field-on/5min field-off, 15min field-on/15min field-off, 30min field-on continuously) and two cell lines (MCF-7 and SH-SY5Y) were used...

Due to the ability of ovarian cancer (OCa) to acquire drug resistance, it has been difficult to develop efficient and safe chemotherapy for OCa. Here, we examined the therapeutic use of a new self-assembled core-shell nanoscale coordination polymer nanoparticle (NCP-Carbo/GMP) that delivers high loadings of carboplatin (28.0±2.6 wt.%) and gemcitabine monophosphate (8.6±1.5 wt.%). A strong synergistic effect was observed between carboplatin and gemcitabine against platinum-resistant OCa cells, SKOV-3, and A2780/CDDP in vitro...

The incidence of esophageal carcinoma is increasing throughout the world. A major obstacle to its treatment is acquired multidrug resistance (MDR) which results in the failure of chemotherapy and patient relapse. Here, we identified that ouabain is capable of reversing MDR to cisplatin (CDDP) in EC109/CDDP cells and explore the possible mechanisms of action. The parental and the MDR cell lines were both sensitive to ouabain with 50 % inhibitory concentration (IC50) values of 258.11 and 710.63 nM, respectively...

The delivery of combination chemotherapy by nanoscale platforms has been demonstrated to enhance cancer treatment in the clinic. Cisplatin (CDDP)-crosslinked, glutathione-sensitive, tumor-targeting micelles based on carboxymethyl chitosan were designed for synergistic cisplatin-doxorubicin (DOX) combination chemotherapy. In our study, DOX was conjugated to carboxymethyl chitosan through a disulfide bond, which was structurally characterized by (1)H NMR. The micelles formed by self-assembly were spherical, with the mean diameter of 274nm...

Osteosarcoma is the most common malignancy of the bones, and although advances in chemotherapy and surgery had been achieved in recent years, the long-term survival rate has reached a plateau. The main reason for this is the aggressive malignant potential and poor response of the disease to chemotherapy. However, several studies have found that tumor resistance is associated with cancer stem cells (CSCs). To address this issue, in the present study, osteosarcoma cells were treated with specially designated concentrations of cisplatin (CDDP) in a mouse model...

Melanoma is one of leading cause of tumor death worldwide. Anti-cancer strategy includes combination of different chemo-therapeutic agents as well as radiation; however these treatments have limited efficacy and induce significant toxic effects on healthy cells. One of most promising novel therapeutic approach to cancer therapy is the combination of anti-cancer drugs with calorie restriction. Here we investigated the effect Cisplatin (CDDP), one of the most potent chemotherapeutic agent used to treat tumors, in association with fasting in wild type and mutated BRAF(V600E) melanoma cell lines...

BACKGROUND: Although cis-diamminedichloro-platinum (CDDP) exhibits strong therapeutic effects in cancer chemotherapy, its adverse effects such as peripheral neuropathy, nephropathy, and vomiting are dose-limiting factors. Previous studies reported that chronotherapy decreased CDDP-induced nephropathy and vomiting. In the present study, we investigated the influence of dosing times on CDDP-induced peripheral neuropathy in rats. METHODS: CDDP (4 mg/kg) was administered intravenously at 5:00 or 17:00 every 7 days for 4 weeks to male Sprague-Dawley rats, and saline was given to the control group...

Stomach cancer carcinomatosis peritonitis (SCCP) is a recalcitrant disease. The goal of the present study was to establish an in vitro-in vivo-like imageable model of SCCP to develop cell-cycle-based therapeutics of SCCP. We established 3-D Gelfoam® histoculture and tumor-sphere models of SCCP. FUCCI-expressing MKN-45 stomach cancer cells were transferred to express the fluorescence ubiquinized cell-cycle indicator (FUCCI). FUCCI-expressing MKN-45 cells formed spheres on agarose or on Gelfoam® grew into tumor-like structures with G0/G1 cancer cells in the center and S/G2 cancer cells located in the surface as indicated by FUCCI imaging when the cells fluoresced red or green, respectively...

Concurrent radiochemotherapy (CRC) is a standard treatment in patients with inoperable locoregionally advanced ear-nose-throat (ENT) cancer. We report the safety and efficacy of CRC with daily fractionated 5-fluorouracil and cisplatin ('F' 5FU-CDDP) in a monocentric retrospective cohort. From January 2006 to August 2012, all patients with unresectable (or inoperable) nonmetastatic locoregionally advanced ENT cancer treated curatively by means of radiotherapy (normal fractionated 70 Gy to the macroscopic tumor and prophylactic 50 Gy) with three courses (week 1-week 4-week 7) of 'F' 5FU-CDDP regimen (800 mg/m/day of 5-fluorouracil and 20 mg/m/day of CDDP from day 1 to day 4) were included...

Antiangiogenic tyrosine kinase inhibitors (TKIs) that target VEGF receptor-2 (VEGFR2) have not been effective as adjuvant treatments for micrometastatic disease in phase III trials. Angiopoietin-2 (Ang2) is a pro-angiogenic and pro-inflammatory vascular destabilizer that cooperates with VEGF. The purpose of this study was to test whether CVX-060 (an Ang2-specific CovX-body) can be combined with VEGFR2-targeting TKIs (sunitinib or regorafenib) to successfully treat postsurgical metastatic disease in multiple orthotopically implanted human tumor xenograft and syngeneic murine tumor models...

We report a case of human epidermal growth factor receptor(HER)2 positive stage IV advanced gastric cancer successfully treated with chemotherapy combined with trastuzumab. A 50-year-old man was diagnosed with type 3 gastric cancer complicated by liver and lymph node metastases. Owing to a HER2 immunohistochemistry tumor score of 3+, we initiated capecitabine plus CDDP plus trastuzumab chemotherapy. After 6 chemotherapy courses, computed tomography showed the liver metastasis had disappeared and the paraaortic lymph nodes had shrunk...

BACKGROUND: During administration of thecisplatin (CDDP)containing regimen, hospitalization is necessary to ensure adequate hydration. However, short hydration is widely used when administering CDDP in outpatient chemotherapy centers. METHOD: To assess the safety of the administration of CDDP during short hydration, we retrospectively evaluated adverse events and complications in the outpatients who received CDDP during short hydration between April 2012 and December 2014 in our hospital...

Chemotherapeutics, including the platinum compounds oxaliplatin (OXP) and cisplatin (CDDP), are standard care of treatment for cancer. Although chemotherapy has long been considered immunosuppressive, evidence now suggests that certain cytotoxic agents can efficiently stimulate antitumor responses, through the induction of a form of apoptosis, called immunogenic cell death (ICD). ICD is characterized by exposure of calreticulin and heat shock proteins (HSPs), secretion of ATP and release of high-mobility group box 1 (HMGB1)...
