Ischaemic preconditioning provides both better intraoperative haemodynamic stability and anti-ischaemic effects thereby allowing us to take full advantage of blood loss reduction by the Pringle manoeuvre.
This large cohort reveals specific histopathological and recurrence patterns for patients with colorectal AC, MAC, and SC. MAC and SC are diagnosed at more advanced tumor stages and therefore entail reduced survival rates.
Hypotheses: Temporary vascular clampage (Pringle maneuver) during liver surgery can cause ischemiareperfusion injury. In this process, activation of polymorphonuclear leukocytes (PMNLs) might play a major role. Thus, we investigated the effects of hepatic ischemic preconditioning on PMNL functions.Design: Prospective randomized study. Patients who underwent partial liver resection were randomly assigned to 3 groups: group 1 without Pringle maneuver; group 2 with Pringle maneuver, and group 3 with ischemic preconditioning using 10 minutes of ischemia and 10 minutes of reperfusion prior to Pringle maneuver for resection.
BACKGROUND: No standard treatment for locally advanced pancreatic cancer (LAPC) is defined. PATIENTS AND METHODS: Within a multi-centre, randomised phase II trial, 95 patients with LAPC were assigned to three different chemoradiotherapy (CRT) regimens: patients received conventionally fractionated radiotherapy of 50 Gy and were randomised to concurrent 5-fluorouracil (350 mg m À2 per day on each day of radiotherapy, RT-5-FU arm), concurrent gemcitabine (300 mg m À2 ), and cisplatin (30 mg m À2 ) on days 1, 8, 22, and 29 (RT-GC arm), or the same concurrent treatment followed by sequential full-dose gemcitabine (1000 mg m À2 ) and cisplatin (50 mg m À2 ) every 2 weeks (RT-GC þ GC arm). Primary end point was the overall survival (OS) rate after 9 months. RESULTS: The 9-month OS rate was 58% in the RT-5-FU arm, 52% in the RT-GC arm, and 45% in the RT-GC þ GC arm. Corresponding median survival times were 9.6, 9.3, and 7.3 months (P ¼ 0.61) respectively. The intent-to-treat response rate was 19, 22, and 13% respectively. Median progression-free survival was estimated with 4.0, 5.6, and 6.0 months (P ¼ 0.21). Grade 3/4 haematological toxicities were more frequent in the two GC-containing arms, no grade 3/4 febrile neutropaenia was observed. CONCLUSION: None of the three CRT regimens tested met the investigators' definition for efficacy; the median OS was similar to those previously reported with gemcitabine alone in LAPC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
