BACKGROUND: To assess the efficacy of concurrent chemoradiotherapy (CCRT) with daily low-dose cisplatin (CDDP) plus weekly docetaxel (DTX) for patients with T2N0 glottic cancer. METHODS: Between January 2004 and December 2013, 62 treatment-naive patients with histologically proven T2N0 glottic cancer were treated with concurrent chemoradiotherapy. Radiation therapy (RT; 2 Gy daily fractions up to a total dose of 66 Gy) was administered in combination with daily low-dose CDDP (6 mg/m(2), five times a week), plus weekly DTX (10 mg/m(2)) for up to 4 weeks from the commencement of RT...

A series of new platinum Pt(II) compounds possessing a bidentate leaving ligand modified from oxaliplatin has been synthesized, with one of the oxygen ligating atom substituted for a sulphur atom (resulting in a Pt-NNSO coordination core structure). The general structures are R,R-diaminocyclohexane (DACH)-Pt-(methylthio)acetic acid (K4) and DACH-Pt-(thiophenylacetic acid) (K4 derivatives). Substitution of an electron donating or withdrawing group at the ortho or para position on the phenyl ring of K4 derivatives was found to affect the complexes' stability, reactivity with the biological molecules (5'-guanosine monophosphate (5'-GMP) and L-methionine (L-Met)) and anticancer activity...

5-fluorouracil (5-FU) and cisplatin (CDDP) are common chemotherapy drugs used in the treatment of patients with advanced esophageal cancer. We investigated the efficacy of adding a continuous infusion of a large dose of a common adjuvant, citrovorumfactor (CF), to the traditional 5-FU/wCDDP regimen. 50 patients with advanced esophageal cancer were treated with a continuous infusion of CF, 5-FU, and CDDP, and the short-term effects, adverse reactions, and survival periods after treatment were analyzed. Overall, the treatment was effective in 58% of patients, and the therapeutic effects of the first-line of chemotherapy were significantly better than the second-line (u = 4...

INTRODUCTION: Cisplatin also known as Cis-Diammine-Dichloroplatinum (CDDP) is a chemotherapeutic alkylating nephrotoxic agent. Thus, it is necessary to know if renal function is normal before starting chemotherapy. Glomerular Filtration Rate (GFR) can be assessed directly by using a radiopharmaceutical (dGFR). Estimated GFR (eGFR) method use, Serum Creatinine (SCR) levels in mathematical formulae such as Cockroft-Gault (CG) and abbreviated. Modified Diet in Renal Disease (aMDRD). The serum creatinine level is a function of GFR but is relatively insensitive for detecting early renal insufficiency...

Neuroblastoma (NB) is a pediatric cancer treated with poly-chemotherapy including platinum complexes (e.g. cisplatin (CDDP), carboplatin), DNA alkylating agents, and topoisomerase I inhibitors (e.g. topotecan (TOPO)). Despite aggressive treatment, NB may become resistant to chemotherapy. We investigated whether CDDP and TOPO treatment of NB cells interacts with the expression and function of proteins involved in regulating calcium signaling. Human neuroblastoma cell lines SH-SY5Y, IMR-32 and NLF were used to investigate the effects of CDDP and TOPO on cell viability, apoptosis, calcium homeostasis, and expression of selected proteins regulating intracellular calcium concentration ([Ca2+]i)...

Lysophosphatidic acid (LPA) is a simple biophysical lipid which interacts with at least six subtypes of G protein-coupled LPA receptors (LPA1-LPA6). In cancer cells, LPA signaling via LPA receptors is involved in the regulation of malignant properties, such as cell growth, motility, and invasion. The aim of this study was to assess whether LPA receptors regulate cellular functions of fibrosarcoma cells treated with anticancer drug. HT1080 cells were maintained by the stepwise treatment of cisplatin (CDDP) at a range of 0...

Therapy against nasopharyngeal carcinoma (NPC) is hurdled by chemoresistance. Recent studies found that microRNA (miRNA) are important regulators of cancer resistance. In this study, we aimed to explore the role and mechanism of miR-26b in regulating NPC cisplatin (CDDP) resistance. Real-time PCR was used to evaluate miR-26b levels in CDDP-resistant and CDDP-sensitive NPC cells, as well as human NPC tissues. MiR-26b was ectopically overexpressed in CDDP-resistant cells, followed by monitoring changes in cell viability and apoptosis...

Following the publication of this article, we realize that there were some errors in the manuscript. Details of the experiments describing the gene silencing of RUNX3 with small interfering RNA (siRNA) were erroneously included in this paper, and all references to siRNA should have been deleted from the manuscript prior to publication. In the subsection entitled 'Cell lines and cell culture' on page 2577, the left‑hand column, the text should have indicated that the human HCC cell lines Hep3B and Huh7 were obtained from the American Type Culture Collection (ATCC; Manassas, VA, USA), whereas HLF cells were obtained from the Japanese Cancer Resources Bank (Tokyo, Japan)...

Platinum-based (Pt) chemotherapy is broadly utilized in the treatment of cancer. Development of more effective, personalized treatment strategies require identification of novel biomarkers of treatment response. Since Pt compounds are inactivated through cellular metabolic activity, we hypothesized that metabolic interrogation can predict the effectiveness of Pt chemotherapy in a pre-clinical model of head and neck squamous cell carcinoma (HNSCC).We tested the effects of cisplatin (CDDP) and carboplatin (CBP) on DNA damage, activation of cellular death cascades and tumor cell metabolism, specifically lactate production...

The role of cluster of differentiation (CD) 24 in breast cancer remains unclear; previously, we showed that CD24 suppresses malignant phenotypes by inactivating Hedgehog signaling through signal transducer and activator of transcription (STAT) 1 inhibition. In this study, we examined how CD24 affects chemosensitivity in breast cancer cells. The CD44(+)CD24(+) breast cancer cell line MCF-7 was transfected with CD24 with/without STAT1 siRNA, and chemosensitivity to 5-fluorouracil (5-FU) and cis-diamminedichloroplatinum (CDDP) was measured...
