Background/Aim: Adenocarcinoma of the pancreas is one of the most aggressive malignant diseases in humans. Characteristics of this tumour type are poor response to radiotherapy and chemotherapeutic agents as well as metastasis in the absence of an organ capsule. The best therapeutic option is surgical removal of the tumour followed by chemotherapy or radiotherapy. Yet, even after surgical R0resection, the 5-year survival probability is only about 20% because of the high recurrence rate of this tumour and complications due to metastases. Furthermore, recent studies have shown that the perioperative period is a particularly vulnerable phase, during which tumour progression and metastasis may be facilitated. The effects of analgesics administered during the perioperative period are still unknown. The present work investigated the effects of analgesics on pancreatic cancer cell migration in vitro. Materials and Methods: The migratory potential of pancreatic cancer cells was analysed using a Cell Migration Assay Kit with a Boyden chamber, in which cells migrate through a semi-permeable membrane under different stimuli. Cell concentration was measured by reading fluorescence (Ex/Em=530/590 nm) in a plate reader. Results: Migration in PANC-1 pancreatic cancer cells was significantly decreased after 24 h stimulation with 100 ,uM of ropivacaine, 100 nM of sufentanil, 1,000 ,uM of ropivacaine and 1,000 nM of sufentanil. In the PaTu 8988t cell line, incubation with 10 ,uM of ropivacaine caused a slight but statistically significant increase in migration, whereas Mathematical modelling of tumour-immune interactions in presence of checkpoint inhibitor-based therapies for the treatment of cancer
