Gemcitabine and cisplatin is the first line chemotherapy for non-small cell lung cancer with high toxicity. Aidi injection is a cantharidin and astragalu-based Chinese herbs injection in China. Has Aidi injection attenuation and synergistic efficacy to GP in NSCLC? There is lack of strong evidence to prove it. To further reveal it, we systematically evaluated all related studies. We collected all studies about Aidi injection plus GP for NSCLC in Medline, Embase, Web of Science, CNKI, VIP, Wanfang Database, CBM, CCRCT, Chi-CTR, and US-clinical trials (established to June 2015)...

The aim was to investigate the clinical efficacy and immunomodulatory effect of lienal polypeptide injection combined with postoperative FOLFOX chemotherapy regimen in colon cancer patients. A total of 84 colon cancer patients were selected between January, 2014 and December, 2015. The selected patients were randomly divided into the observation (42 patients) and control (42 patients) groups. The observation group patients were treated with FOLFOX chemotherapy regimen combined with lienal polypeptide, whereas, the control group patients were treated with FOLFOX chemotherapeutic regimen only...

Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of paclitaxel and other chemotherapeutic agents. Paclitaxel binds and stabilizes microtubules, but the cellular mechanisms that underlie paclitaxel's neurotoxic effects are not well understood. We therefore used primary cultures of adult murine dorsal root ganglion neurons, the cell type affected in patients, to examine leading hypotheses to explain paclitaxel neurotoxicity. We address the role of microtubule hyperstabilization and its downstream effects...

Cognitive impairment termed chemobrain is a common neurotoxicity associated with chemotherapy treatment, affecting an estimated 78% of patients. Prompted by the hypothesis that neuronal mitochondrial dysfunction underlies chemotherapy-induced cognitive impairment (CICI), we explored the efficacy of administering the small molecule pifithrin (PFT)-µ, an inhibitor of mitochondrial p53 accumulation, in preventing CICI. Male C57BL/6J mice injected with cisplatin +/- PFT-µ for two 5-day cycles were assessed for cognitive function using novel object/place recognition and alternation in a Y-maze...

Intrathecal chemotherapy with methotrexate, a folate antagonist, is widely used to treat central nervous system malignancies. The mechanisms underlying methotrexate-induced neurotoxicity are unclear but may be related to increased homocysteine levels. Intrathecal methotrexate-induced myelopathy mimicking sub-acute combined degeneration, with normal B12 levels, has been documented. We examined treatment and magnetic resonance imaging (MRI) characteristics of 13 patients with leukemia who received intrathecal methotrexate and developed urinary and bowel incontinence, ascending motor weakness, and sensory loss with dorsal column hyper-intensity on MRI between 2000 and 2016...

Introduction T-cell acute lymphoblastic leukemia (ALL) and lymphoma (LBL) are aggressive hematologic neoplasms that are treated with combination chemotherapy in the frontline, but have limited options in the relapsed or refractory setting. Based on observations in patients with purine nucleoside phosphorylase (PNP) deficiency, a guanosine nucleoside analogue, arabinosylguanine (ara-G) was developed that provided T-cell specificity. Nelarabine was developed as the water-soluble, clinically useful-prodrug of ara-G and based on its activity was approved for the treatment of relapsed or refractory T-ALL/LBL...

Chemotherapy-induced neurotoxicity of peripheral nervous system (PNS) hinders efficacy of cancer treatments. Mechanisms initiating PNS injury by anticancer drugs are incompletely understood delaying development of effective management strategies. To understand events triggered in PNS by cancer drugs, we exposed dorsal root ganglion (DRG) neurons to cisplatin, a drug from platinum-based class of chemotherapeutics frequently implicated in peripheral neuropathies. While cisplatin enters cancer cells and forms cisplatin/DNA crosslinks that block cell proliferation, circulating cisplatin can also reach the PNS and produce crosslinks that impede critical DNA transactions in postmitotic neurons...

Gastrointestinal (GI) side-effects of chemotherapy are a debilitating and often overlooked clinical hurdle in cancer management. Chemotherapy-induced constipation (CIC) and Diarrhea (CID) present a constant challenge in the efficient and tolerable treatment of cancer and are amongst the primary contributors to dose reductions, delays and cessation of treatment. Although prevalence of CIC is hard to estimate, it is believed to affect approximately 16% of cancer patients, whilst incidence of CID has been estimated to be as high as 80%...

Cancer survivors diagnosed during infancy and adolescence may be at risk for chemotherapy-related cognitive impairments (CRCI), however the effects of pediatric chemotherapy treatment on adulthood cognitive function are not well understood. Impairments in memory, attention and executive function affect 15-50% of childhood leukemia survivors related to methotrexate exposure. Systemic cisplatin is used to treat a variety of childhood and adult cancers, yet the risk and extent of cognitive impairment due to platinum-based chemotherapy in pediatric patients is unknown...

BACKGROUND: Although in recent years, the introduction of novel chemotherapy protocols has improved the outcome of T cell acute lymphoblastic leukemia (T-ALL) patients, refractory and/or relapsing disease remains a foremost concern. In this context, a major contribution was provided by the introduction of the nucleoside analog nelarabine, approved for salvage treatment of T-ALL patients with refractory/relapsed disease. However, nelarabine could induce a life-threatening, dose-dependent neurotoxicity...

Combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) is an active but not well-tolerated regimen for advanced gastric cancer (GC) with standard 3-weekly doses. Several modified schedules (mDCFs) have been designed to reduce acute toxicities and improve feasibility as first-line therapy in patients with metastatic GC. The objective of this systematic review was to evaluate overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade (G) greater than or equal to 3 adverse event of mDCF chemotherapy in this setting...

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...

Emergency departments (EDs) are alert to the possibility of stroke and the need for early interventions to improve long-term clinical outcomes. However, new-onset hemiparesis in pediatric patients with leukemia may be due to a number of different etiologies, including most common side effects from chemotherapeutic agents. We present a case of a 15-year-old boy with pre-B acute lymphoblastic leukemia on chemotherapy, having recently received a high-dose methotrexate infusion in addition to intrathecal methotrexate therapy, who presented to our ED with acute right-sided hemiparesis...
