- The past 5 years have seen the clear recognition that the administration of chemotherapy to patients with initially unresectable colorectal liver metastases can increase the number of patients who can undergo potentially curative secondary liver resection. Coupled with this, recent data have emerged that show that perioperative chemotherapy confers a disease-free survival advantage over surgery alone in colorectal cancer (CRC) patients with initially resectable liver disease. The purpose of this paper is to build on the existing knowledge and review the issues surrounding the use of chemotherapy +/- targeted agents combined with surgery in the treatment of CRC patients with liver metastases, with a view to providing clinical recommendations. An international panel of 21 experts in colorectal oncology comprising liver surgeons and medical oncologists reviewed the available evidence. In a major change to clinical practice, the panel's recommendation was that the majority of patients with CRC liver metastases should be treated up front with chemotherapy, irrespective of the initial resectability status of their metastases.

- Background Surgical resection alone is regarded as the standard of care for patients with liver metastases from colorectal cancer, but relapse is common. We assessed the combination of perioperative chemotherapy and surgery compared with surgery alone for patients with initially resectable liver metastases from colorectal cancer. Methods This parallel-group study reports the trial's final data for progression-free survival for a protocol unspecified interim time-point, while overall survival is still being monitored. 364 patients with histologically proven colorectal cancer and up to four liver metastases were randomly assigned to either six cycles of FOLFOX4 before and six cycles after surgery or to surgery alone (182 in perioperative chemotherapy group vs 182 in surgery group). Patients were centrally randomised by minimisation, adjusting for Centre and risk score. The primary objective was to detect a hazard ratio (HR) of 0.71 or less for progression-free survival. Primary analysis was by intention to treat. Analyses were repeated for all eligible (171 vs 171) and resected patients (151 vs 152). This trial is registered with ClinicalTrials.gov, number NCT00006479. Findings In the perioperative chemotherapy group, 151 (83%) patients were resected after a median of six (range 1-6) preoperative cycles and 115 (63%) patients received a median six (1-8) postoperative cycles. 152 (84%) patients were resected in the surgery group. The absolute increase in rate of progression-free survival at 3 years was 7.3% (from 28.1% [95-66% CI 21.3-35.51 to 35.4% [28.1-42.7]; HR 0 . 79 [0.62-1.02]; p=0.058) in randomised patients; 8 . 1% (from 28.1% [21.2-36.6] to 36.2% [28.7-43.8]; HR 0 . 77 [0-60-1 . 001; p=0 . 041) in eligible patients; and 9.2% (from 33.2% [25.3-41.2] to 42.4% [34.0-50.5]; HR 0.73 [0.55-0.97]; p=0.025) in patients undergoing resection. 139 patients died (64 in perioperative chemotherapy group vs 75 in surgery group). Reversible postoperative complications occurred more often after chemotherapy than after surgery (40/159 [25%] vs 27/170 [16%]; p=0.04). After surgery we recorded two deaths in the surgery alone group and one in the perioperative chemotherapy group. Interpretation Perioperative chemotherapy with FOLFOX4 is compatible with major liver surgery and reduces the risk of events of progression-free survival in eligible and resected. patients.

- Background Previous results of the EORTC intergroup trial 40983 showed that perioperative chemotherapy with FOLFOX4 (folinic acid, fluorouracil, and oxaliplatin) increases progression-free survival (PFS) compared with surgery alone for patients with initially resectable liver metastases from colorectal cancer. Here we present overall survival data after long-term follow-up. Methods This randomised, controlled, parallel-group, phase 3 study recruited patients from 78 hospitals across Europe, Australia, and Hong Kong. Eligible patients aged 18-80 years who had histologically proven colorectal cancer and up to four liver metastases were randomly assigned (1:1) to either perioperative FOLFOX4 or surgery alone. Perioperative FOLFOX4 consisted of six 14-day cycles of oxaliplatin 85mg/m(2), folinic acid 200 mg/m(2) (DL form) or 100 mg/m2 (L form) on days 1-2 plus bolus, and fluorouracil 400 mg/m(2) (bolus) and 600 mg/m(2) (continuous 22 h infusion), before and after surgery. Patients were centrally randomised by minimisation, adjusting for centre and risk score and previous adjuvant chemotherapy to primary surgery for colorectal cancer, and the trial was open label. Analysis of overall survival was by intention to treat in all randomly assigned patients. This trial is registered with ClinicalTrials.gov, number NCT00006479. Findings Between Oct 10, 2000, and July 5, 2004, 364 patients were randomly assigned to a treatment group (182 patients in each group, of which 171 per group were eligible and 152 per group underwent resection). At a median follow-up of 8.5 years (IQR 7.6-9.5), 107 (59%) patients in the perioperative chemotherapy group had died versus 114 (63%) in the surgery-only group (HR 0.88, 95% CI 0.68-1.14; p=0.34). In all randomly assigned patients, median overall survival was 61.3 months (95% CI 51.0-83.4) in the perioperative chemotherapy group and 54.3 months (41.9-79.4) in the surgery alone group. 5-year overall survival was 51.2% (95% CI 43.6-58.3) in the perioperative chemotherapy group versus 47.8% (40.3-55.0) in the surgery-only group. Two patients in the perioperative chemotherapy group and three in the surgery-only group died from complications of protocol surgery, and one patient in the perioperative chemotherapy group died possibly as a result of toxicity of protocol treatment. Interpretation We found no difference in overall survival with the addition of perioperative chemotherapy with FOLFOX4 compared with surgery alone for patients with resectable liver metastases from colorectal cancer. However, the previously observed benefit in PFS means that perioperative chemotherapy with FOLFOX4 should remain the reference treatment for this population of patients.

- Introduction: Thrombus ages, defined as four relative age phases, are related to different compositions of the intraluminal thrombus (ILT) in the abdominal aortic aneurysm (AAA) (Tong et al., 2011b). Experimental studies indicate a correlation between the relative thrombus age and the strength of the thrombus-covered wall. Methods: On 32 AAA samples we performed peeling tests with the aim to dissect the material (i) through the ILT thickness, (ii) within the individual ILT layers and (iii) within the aneurysm wall underneath the thrombus by using two extension rates (1. mm/min, 1. mm/s). Histological investigations and mass fraction analysis were performed to characterize the dissected morphology, to determine the relative thrombus age, and to quantify dry weight percentages of elastin and collagen in the AAA wall. Results: A remarkably lower dissection energy was needed to dissect within the individual ILT layers and through the thicknesses of old thrombi. With increasing ILT age the dissection energy of the underlying intima-media composite continuously decreased and the anisotropic dissection properties for that composite vanished. The quantified dissection properties were rate dependent for both tissue types (ILT and wall). Histology showed that single fibrin fibers or smaller protein clots within the ILT generate smooth dissected surfaces during the peeling. There was a notable decrease in mass fraction of elastin within the thrombus-covered intima-media composite with ILT age, whereas no significant change was found for that of collagen. Conclusions: These findings suggest that intraluminal thrombus aging leads to a higher propensity of dissection for the ILT and the intima-media composite of the aneurysmal wall.

- Pancreatic cancer is a disease requiring urgent attention from governments and policymakers. Recently, a state of emergency has been declared for this cancer—being the fourth most common cause of cancer deaths in the European Union, it has the lowest survival rate of all common cancers. One of the major reasons pancreatic cancer is associated with such poor outcomes is because it is usually diagnosed at a late stage. Also, investment in research for effective targeted therapies is lacking. This is the perspective of a white paper developed by Digestive Cancers Europe, an umbrella organisation representing European patient organisations. It has been developed after consultation with pancreatic cancer patients, representatives of cancer patient organisations and leading pancreatic cancer healthcare professionals. The purpose of the paper is to highlight the key urgent unmet needs in pancreatic cancer from the patient perspective, ultimately with a view to improve patient care and outcomes in this very challenging disease.
