CIPN

This is a pilot, observational, cross-sectional, study on socio-economic burden related to chemotherapy-induced peripheral neurotoxicity (CIPN). Investigators will collect CIPN healthcare related costs on a detailed clinical patient-level. As a sub-study, data obtained in this cross-sectional study, will be compared with administrative larger datasets on patients affected by cancer. The aim is to run a test for potential proxy variables which are available in larger administrative datasets, even if not directly measuring CIPN, to learn more about the impact of CIPN.

To conduct a two-arm, parallel, prospective, randomized controlled, open-label trial to compare the efficacy of the novel drug mirogabalin with the conventional treatment duloxetine in reducing pain associated with chemotherapy-induced peripheral neuropathy (CIPN). There will be a difference in pain reduction after 4 weeks of treatment between the mirogabalin group and the duloxetine group in patients with chemotherapy-induced peripheral neuropathy (CIPN). Participants will: * Take drug duloxetine or a mirogabalin every day for 4 weeks. * Visit the clinic once every 2 weeks for checkups and tests
