The BRAF activating mutation, harbored by approximately 10% of colorectal cancers (CRC), confers dramatic prognosis to advanced diseases. In early-stage setting, the identification of the BRAF mutation does not impact the therapeutic decision. Yet, the BRAF mutation could be considered as a stratification factor in adjuvant trials, because of its prognostic impact after relapse. Moreover, both BRAF mutation and mismatch repair (MMR) statuses should be determined in all CRC to help identify sporadic tumors versus Lynch syndrome-related tumors...

PURPOSE: Fluorouracil and folinic acid with irinotecan (FOLFIRI) plus bevacizumab (BV) is widely used as second-line chemotherapy for patients with metastatic colorectal cancer (mCRC) previously treated with fluoropyrimidines, oxaliplatin, and BV. FOLFIRI requires a CV catheter and an infusion pump, which are inconvenient for patients. Sufficient data are not available for characterizing the effectiveness of fluoropyrimidines beyond first disease progression. In this study, we evaluated the efficacy and safety of irinotecan (CPT-11) plus BV as second-line therapy...

Non-classical secretory vesicles, collectively referred to as extracellular vesicles (EVs), have been implicated in different aspects of cancer cell survival and metastasis. Here, we describe how a specific class of EVs, called microvesicles (MVs), activates VEGF receptors and tumour angiogenesis through a unique 90 kDa form of VEGF (VEGF90K). We show that VEGF90K is generated by the crosslinking of VEGF165, catalysed by the enzyme tissue transglutaminase, and associates with MVs through its interaction with the chaperone Hsp90...

There is no standard therapy for recurrent anaplastic glioma (AG). Salvage therapies include alkylator-based chemotherapy, re-resection with or without carmustine implants, re-irradiation and bevacizumab. Bendamustine is a novel bifunctional alkylator with CNS penetration never previously evaluated in AG. Assess response and toxicity of bendamustine in recurrent AG in a phase II trial. Adults with radiation and temozolomide refractory recurrent AG were treated with bendamustine. A cycle of bendamustine was defined as two consecutive days of treatment (100 mg/m(2)/day) administered once every 4 weeks...

It has been reported that many patients with lung metastasis of colorectal cancer (CRC) underwent chemotherapy with fluorouracil, folinic acid, oxaliplatin, irinotecan, or capecitabine. There is a small number of reports about the capecitabine and irinotecan (XELIRI) plus bevacizumab (BV) therapy for patients with metastatic CRC in Japan. We report a case of successful BV+XELIRI therapy for rectal cancer with multiple lung metastases as first-line chemotherapy. A 53-year-old female presented with advanced rectal cancer and metastatic lung tumors...

AIMS: Glioblastoma cancer stem-like cells (GCSCs) promote themselves proliferation by secreting the vascular endothelial growth factor A (VEGFA) in an autocrine manner, positively regulated by phosphodiesterase IV (PDE4). In the current study, we investigated the putative cytotoxic effect of bevacizumab, a VEGFA blocker, alone and in combination with a specific inhibitor of PDE4 called rolipram on GCSCs isolated from human surgical tumor specimen with a focus on PI3K/AKT pathway. MAIN METHODS: CD133+/CD15+ GCSCs were characterized by flow cytometry and expanded in a serum-free primary culture system...
