The aim of this study was to evaluate the association between thymidylate synthase (TS), methylenetetrahydrofolate reductase (MTHFR) and reduced folate carrier (SLC19A1) gene polymorphisms and the treatment efficacy of pemetrexed-based chemotherapy in advanced non-small cell lung cancer (NSCLC). Advanced NSCLC patients received pemetrexed and cisplatin every three weeks. Polymorphisms in the TS...

Cytoreductive surgery (CRS) with heated intraoperative intraperitoneal chemotherapy (HIPEC) has emerged as optimal treatment for diffuse malignant peritoneal mesothelioma (DMPM) showing median survivals of 36-92 months. However, recurrences occur frequently even in patients undergoing optimal cytreduction and are often confined to the abdomen. We initiated a Phase II study of adjuvant intraperi...

Pemetrexed (ALIMTA, Lilly) is a folate antimetabolite that has been approved by the U.S. Food and Drug Administration for the treatment of non-small cell lung cancer and has been shown to stimulate autophagy. In the present study, we sought to further understand the role of autophagy in response to pemetrexed and to test if combination therapy could enhance the level of toxicity through altered...

PURPOSE Due to the rarity of thymic epithelial tumors (TET), no standard chemotherapy regimen has been identified in the relapsed setting. The aim of this study was to investigate the activity of a pemetrexed-based regimen in advanced TET as palliative treatment after failure of previous chemotherapy, and to detect its association with thymidylate synthetase (TS) level. METHODS Patients with ...

Pemetrexed represents the first antifolate cancer drug to be approved by the Food and Drug Administration in 20 years; it is currently in widespread use for first line therapy of mesothelioma and non-small cell lung cancer. Pemetrexed has more than one site of action; the primary site is thymidylate synthase. We now report that the secondary target is the downstream folate-dependent enzyme in d...

BACKGROUND Despite initial treatment with high-dose methotrexate-based regimens, many patients with primary central nervous system lymphoma (PCNSL) relapse and die from their disease. No standard of care exists at progression or relapse, but chemotherapy and in some cases radiation are usually used. Pemetrexed is a multitargeted antifolate, similar to methotrexate, but with a broader spectrum o...

OBJECTIVE The objective of this study was to compare hospital costs per treatment cycle (HCTC) for nonchemotherapy drugs and nondrug care associated with platinum-based doublets in the first-line setting for advanced nonsquamous non-small-cell lung cancer (AdvNS-NSCLC) in Chinese patients. METHODS Patients receiving platinum-based doublets in the first-line setting for AdvNS-NSCLC from 2010 t...

BACKGROUND Ku80 is a DNA repair protein which involves in cell apoptosis and chemoresistance. However, it is unclear whether Ku80 correlates with the efficiency of neoadjuvant chemotherapy in human lung adenocarcinoma, and modulates cisplatin/pemetrexed-induced lung cancer cell apoptosis in vitro. METHODS We recruited 110 patients with stage IIIA lung adenocarcinoma, who received 2 cycles of ...

To determine the efficacy and toxicity of Pemetrexed plus Oxaliplatin in patients suffering from stage IIIb or IV lung adenocarcinoma and being treated with Erlotinib as second-line treatment, a total of 45 patients were randomly divided into two groups. One group was treated with 500 mg/m(2) Pemetrexed plus 100 mg/m(2) Oxaliplatin, and the other was treated with 500 mg/m(2) Pemetrexed plus 75 ...

INTRODUCTION Two standard single-agent chemotherapy treatments (docetaxel and pemetrexed) were combined in this trial and administered as second-line treatment in patients with non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the safety and feasibility of combining docetaxel with pemetrexed. METHODS Six patients were enrolled between August 2007 and March 2009 with st...
