Filter by:Study Design: This is a pragmatic study on the management strategy for patients with metastatic colorectal cancer (CRC) who are candidates for CT, independently of any previous adjuvant therapy received. The aim of this study is to define the role of new target molecules in combination with CT in first- and second line treatment. First line study: Eligible patients were randomized to either treatment: Arm A: FOLFIRI or FOLFOX + Bevacizumab, cycle to be repeated every 2 weeks - BEVACIZUMAB: Day 1,1st cycle 5 mg/kg IV infusion of 90 min Day 1, 2nd cycle if well tolerated, 5 mg/kg IV infusion of 60 min Day 1, 3rd cycle and subsequent cycles if well tolerated, 5 mg/kg IV infusion of 30 min after 5-Fluorouracile (FU) bolus - FOLFIRI Day 1: Irinotecan 180 mg/m2 IV infusion 30-90 min Day 1,2: L-Folinic acid 100 mg/m2 IV infusion of 2 hours 5-Fluorouracil 400 mg/m2 as a bolus 5-Fluorouracil 600 mg/m2 continuous IV infusion of 22 hours - FOLFOX Day 1: Oxaliplatin 85 mg/m2 IV infusion of 2hours Day 1,2: L-Folinic acid 100 mg/m2 IV infusion of 2 hours 5-Fluorouracil 400 mg/m2 as a bolus 5-Fluorouracil 600 mg/m2 continuous IV infusion of 22 hours Arm B: FOLFIRI or FOLFOX, cycle to be repeated every 2 weeks If FOLFIRI: FOLFIRI as specified in arm A without Bevacizumab If FOLFOX: FOLFOX as specified in arm A without Bevacizumab Duration of Therapy For both arms, CT was repeated until progressive disease (PD) or unacceptable toxicity occurs. If unacceptable CT-related toxicity occurs in ARM A, in the absence of PD patients stopped CT and continued with only bevacizumab 5 mg/kg as a 30-min infusion every 2 weeks until progression or intolerable toxicity occurred. Second line - it is divided in two different studies (2A and 2B): Study 2A: Patients from arm A and Kras Wild Type were randomized to: - Arm C: FOLFIRI or FOLFOX (the CT schedule not received in 1st line trial, as defined in arm B) - Arm D: FOLFIRI or FOLFOX (the CT schedule not received in 1st line trial, as described in arm B) plus CETUXIMAB CETUXIMAB 1st cycle Day 1 400 mg/m2 infusion of 120 min 2 hrs before CT infusion 1st cycle Day 8 and subsequent cycles 250 mg/m2 infusion of 60 min 1 hr before CT infusion Patients from arm A and Kras Mutant were treated according to arm C. Study 2B: Patients from arm B and Kras Wild Type were randomized to: - Arm E: FOLFIRI or FOLFOX (the CT schedule not received in the 1st line trial, as defined in arm B) plus BEVACIZUMAB - Arm F: FOLFIRI or FOLFOX (the CT schedule not received in the first-line trial, as defined in arm B) plus BEVACIZUMAB and CETUXIMAB; cycle to be repeated every 2 weeks, whilst cetuximab will be administered weekly. - BEVACIZUMAB 2nd day of 1st cycle 5 mg/kg IV infusion of 90 min 2nd day of 2 nd cycle if well tolerated, 5 mg/kg IV infusion of 60 min 2nd day of 3 rd cycle and subsequent cycles if well tolerated, 5 mg/kg IV infusion of 30 min after the end of 5-FU bolus on the 2nd day - CETUXIMAB 1st cycle Day 1 400 mg/m2 infusion of 120 min 2 hr before CT infusion 1st cycle Day 8 and subsequent cycles 250 mg/m2 infusion of 60 min 1 hr before CT infusion If cetuximab will be stopped for any of the reasons specified in this protocol, bevacizumab will be administered as defined in arm A of the 1st line study Patients from arm B and Kras Mutant were treated according to arm E. Objectives of study The primary objective of the 1st line study is to determine whether the addition of bevacizumab to a poly-chemotherapy (polyCT) regimen (FOLFIRI or FOLFOX) improves efficacy in terms of progression-free survival (PFS). The secondary objectives of the 1st line study are to determine the Overall Response Rate (ORR) and the safety profile of the treatments administered. The primary objective of the 2nd line studies is to determine, separately for each study, whether the addition of cetuximab to a polyCT schemes (FOLFOX or FOLFIRI), or to polyCT schemes plus bevacizumab, improves efficacy in terms of PFS.The secondary objectives of the 2nd line studies are to determine the ORR, the overall survival (OS) and the safety profile of the treatments administered.
The implementation of screening programs for colorectal cancer by screening for fecal occult blood has proven effective in reducing the incidence and mortality from this type of neoplasms. However, to ensure the efficiency of the programs require population participation rates of at least 50%. Experiences in our country show that the population participation is far from this recommended minimum number. Interventions to promote preventive activities in primary care are well received by the population; in the case of colorectal cancer, direct recommendation of primary care professionals to carry out the screening is one of the factors with greatest impact on increasing population participation in such programs. Care overload, circuit design for screening without the direct intervention of primary care professionals and the multiplicity of tasks that they must face, are elements that influence the low recommendation for screening in the target population who consults for any other reason. The introduction of specific reminders in electronic medical record (in widespread use in primary care), as a tool to facilitate and encourage direct referral by physicians and nurse practitioners to perform colorectal cancer screening will mean an increase of at least 10% in participation of the target population, increasing the efficiency of screening programs. The introduction of this new software tool will have good acceptance and increase compliance with recommendations from health professionals.
This study will be looking at whether MK-3475 (an antibody that blocks negative signals to T cells) is effective (anti-tumor activity) and safe in three different patient populations. These include: 1. patients with MSI positive colon cancer, 2. patients with MSI negative colon cancer and 3. patients with other MSI positive cancers.

The purpose of this prospective clinical study is to establish the feasibility and usability of the ENDORINGS™ when used during standard colonoscopy procedure.
Nordic randomized phase II trial which evaluates whether biweekly cetuximab with alternating FOLFIRI and mFOLFOX6 is more effective than biweekly cetuximab with continuously FOLFIRI in patients with potential resectable KRAS wildtype metastatic colorectal cancer. All patients will be randomized to biweekly cetuximab 500 mg/m2 in combination with arm A) FOLFIRI (irinotecan 180 mg/m2 IV, leucovorin: 400 mg/m2 IV, 5FU bolus: 400 mg/m2 IV and 46 hours 5FU infusion of 2400 mg/m2 every 2 weeks) or arm B) FOLFIRI alternating with FOLFOX6 (Oxaliplatin: 85 mg/m2 IV, leucovorin: 400 mg/m2 IV, 5FU bolus: 400 mg/m2 IV and 46 hours 5FU infusion of 2400 mg/m2 every 2 weeks) . Primary objective: response rate (RECIST 1.1) in patients with with potential resectable KRAS wildtype metastatic colorectal cancer. Secondary objectives: Resection rate, PFS, OS, Quality of life, tolerability. Biomarker evaluation to measure plasma biomarkers, Tumour blocks and sequential serum and plasma will be collected to search for markers that may predict efficacy including respectability and safety.
Recruitment to phase I of the PANTHER trial is complete. Phase II, is to evaluate the best overall response rate for AZD8931 + FOLFIRI treatment.
Curcumin is an extract of the tumeric root that has been shown to have anti-tumor properties in laboratory studies. Curcumin, and its parent spice, turmeric (curcuma longa), are the 4th most commonly purchased dietary supplement in the U.S. Many cancer patients take curcumin during their treatment for cancer because of the purported health benefits. This research study is designed to learn more about the safety, pharmacokinetics and effectiveness of irinotecan when given in combination with curcumin in patients with metastatic colorectal cancer. The study of how the body absorbs, processes and eliminates drugs is called pharmacokinetics (PK). One of the main purposes of this study is to better understand the interaction between curcumin and irinotecan by measuring levels of irinotecan in the blood (ie. measure irinotecan PK) when a patient also takes curcumin. Information collected from this study could result in improved dosing guidelines and lead to more effective treatment of your cancer with less toxicity.
The study is designed to analyze the pathological tumor response on resected colorectal cancer metastases after preoperative treatment with bevacizumab combined with FOLFOX or FOLFIRI regimen in a prospective cohort and to correlate this response with patient's outcome.
Bevacizumab in combination with chemotherapy represents a standard of care for first-line treatment in patients with advanced colorectal cancer. Molecular predictive factors for bevacizumab efficacy have not yet been identified therefore selection of patients more likely to benefit from such a treatment approach is not possible. Retrospective analyses suggested that LDH serum levels may influence the clinical activity of anti-angiogenetic drugs. Primary aim of our clinical trial will be to prospectively ascertain whether bevacizumab in combination with chemotherapy has an improved clinical activity in patients with high LDH serum levels compared to patients with normal LDH serum levels
