The CHAMP (Chemotherapy, Host response And Molecular dynamics in Periampullary cancer) study is a prospective, single-arm observational study that will start Sept 1 2018. All patients diagnosed with a histologically or cytologically confirmed diagnosis of pancreatic or other periampullary adenocarcinoma undergoing adjuvant or palliative chemotherapy treatment in the Department of Oncology, Skåne University Hospital, Malmö will be invited to participate. The estimated number of recruited patients is 90/year, 75 with pancreatic cancers.
Patients will be informed about the study by their oncologist and a research nurse and, if they want to participate, will sign an informed consent form. The treatment regimen will follow national guidelines, and will not be affected by the study. Clinical and pathological data will be compiled at study entry. Radiological and clinical workup will be performed every three months. Primary endpoint will be overall survival, secondary endpoints will be disease specific survival, time to progression, and quality of life.
Serial sampling of blood during chemotherapy treatment will be performed by a dedicated research nurse along with the clinical routine sampling. Plasma and serum samples for analysis of ctDNA and cytokines, respectively, will be will be drawn before chemotherapy start, and prior to each additional course of chemotherapy.
