We established new pemetrexed-resistant cells originating from malignant pleural mesothelioma MSTO-211H cells to clarify the mechanism involved in pemetrexed resistance in malignant pleural mesothelioma. In the pemetrexed-resistant cells, only thymidylate synthase (TYMS) mRNA was overexpressed among other well-known molecular targets and chemosensitivity determinants of pemetrexed, and the role...

PURPOSE This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed-based chemoradiotherapy in treating patients with locally advanced or metastatic esophageal cancer. METHODS Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for relevant patients were identified using a predefined search strategy. Pooled respo...

PURPOSE Both gefitinib and pemetrexed maintenance were effective therapies for advanced lung adenocarcinoma, but which is better is unclear. For patients with advanced lung adenocarcinoma, we have no idea whether we should choose gefitinib or pemetrexed maintenance in clinical practice. Here, we assessed the efficacy and tolerability of gefitinib versus pemetrexed maintenance in these patients....

PURPOSE To compare supportive care costs associated with second-line chemotherapy for advanced non-squamous non-small cell lung cancer (advNS-NSCLC) in Chinese patients. METHODS This retrospective cohort study included patients receiving pemetrexed or docetaxel-based second-line chemotherapy for advNS-NSCLC in four Chinese hospitals from 2007 to 2012. The best matched pairs between pemetrexed...

PURPOSE This phase I study evaluated the effect of folate supplementation on the toxicity, tolerability, and pharmacokinetics of pemetrexed in patients with locally advanced or metastatic cancer. It also examined two different types of vitamin supplementation and whether the extent of prior myelosuppressive therapy affected pemetrexed tolerability. PATIENTS AND METHODS Patients received a 10-...

Introduction Inhibition of thymidylate synthase (TS) results in a transient compensatory "flare" in thymidine salvage pathway activity measureable with 18F-thymidine (FLT)- positron emission tomography (PET) at 2hrs. of therapy which may predict non-small cell lung cancer (NSCLC) sensitivity to TS inhibition. Materials and Methods Resistance to TS inhibition by pemetrexed was induced in NSCLC...

OBJECTIVES This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. METHODS PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publi...

INTRODUCTION Non-small cell lung cancer (NSCLC) is a major cause of cancer-related death worldwide. Although advanced NSCLC is still incurable, various anti-neoplastic agents have become available for the treatment of this disease. Pemetrexed , a multi-target folate antagonist, has improved the survival of non-squamous NSCLC patients. Currently, pemetrexed is approved for first-line treatment i...

Indian Journal of Nephrology | Volume 27 | Issue 3 | May-June 2017 243 Sir, Pemetrexed is an antifolate agent approved for the treatment of non‐small cell lung cancer. A 62 year old male was admitted to our hospital in December 2014. He was diagnosed with metastatic non‐small cell lung cancer. He was treated with first‐line chemotherapy, including paclitaxel infusions and carboplatin, every 3 w...

BACKGROUND Pemetrexed is currently recommended as the second-line treatment for patients with advanced non-small-cell lung cancer (NSCLC). However, it is unclear whether pemetrexed-based doublet therapy improves treatment efficacy and safety. Thus, this meta-analysis was performed to resolve this controversial question. METHODS Electronic databases, including PubMed, Embase, and the Cochrane ...
