PURPOSE Pancreatic cancers are resistant to radiotherapy (RT) and current chemotherapy agents. Epidermal growth factor receptor is overexpressed in pancreatic cancer, and in vitro studies have shown that epidermal growth factor receptor inhibitors can overcome radio- and chemoresistance. The aim of the study was to determine whether the addition of(More)
PURPOSE Oxaliplatin-5-fluorouracil combinations have increased responses in first-line therapy up to 40% in advanced colorectal cancer. Unfortunately, those patients who will respond are unknown and initially sensitive patients become rapidly resistant to current therapies. FAS (CD95) and FAS ligand (FASL; CD95L) have been implicated in chemosensitivity(More)
PURPOSE To define the maximum-tolerated dose of oxaliplatin given with cisplatin, protacted 96-h infusion of fluorouracil, and radiotherapy for patients with advanced esophageal cancer. PATIENTS AND METHODS Seventeen patients with locally advanced esophageal cancer and 2 patients with local recurrence were treated. Escalating doses of oxaliplatin,(More)
The purpose of the study was to prospectively explore the role of serum MMP-7 as a predictive and prognostic marker of anti-epidermal growth factor receptor (EGFR) therapy and irinotecan efficacy in third-line advanced colorectal cancer therapy. One hundred patients were recruited prospectively from six Spanish hospitals. Patients were treated with biweekly(More)
Background: To analyze the feasibility of capecitabine with weekly irinotecan and concurrent radiotherapy followed by laparoscopic-total mesorectal excision (LTME) in rectal cancer patients. Methods: Eligible criteria included adenocarcinoma of the rectum staged by endoscopic ultrasonography (u), spiral abdominal and pelvic CT and chest X-ray. Patients(More)
INTRODUCTION Whole brain irradiation (WBRT) remains a recommended treatment for patients with brain metastases from malignant melanoma in terms of symptom palliation, especially when extracranial systemic disease is present. Temozolomide (TMZ) has shown efficacy in the treatment of metastatic melanoma. The objective was to evaluate the potential benefit in(More)
Metalloproteinase 7 (MMP-7) plays an important role in tumor growth, invasion and dissemination, and is secreted to the media. Because of the close implication of MMP-7 in cancer biology, we sought to define the prognostic significance of serum levels of MMP-7 in metastatic colorectal cancer (CRC) and explore its possible impact in the daily clinical(More)
The FAS/FASL system, comprising membrane-bound (mFAS and mFASL) and soluble forms (sFAS and sFASL), has been related to apoptosis driven by chemotherapy administration. In vitro experiments show chemotherapy upregulating membrane-bound forms, leading to an increase of receptor availability (at 24-72 h) and favoring apoptosis. The regulatory effect of(More)
AIM To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy. METHODS Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of(More)
INTRODUCTION Chemotherapy is the principal treatment in metastatic colorectal cancer (mCRC) patients. RAC1b, a RAC1 spliced variant, is over-expressed in colorectal cancer (CRC), and impairs apoptosis by activation of nuclear-factor-KB. Since RAC1b has been associated with the BRAF(V600E) mutation, associated with poor prognosis in CRC, we evaluated the(More)
