Procedure
The participants were recruited to this study right after randomization in the CryoPac study, in connection with the first neurophysiological evaluation. The first interview took place immediately after inclusion and contained questions about their motivation to participate in the trial. The second interview took place at either the 8th treatment with paclitaxel or in connection with the second neurophysiological evaluation after end of treatment. The second interview contained questions about the participants’ experience of being part of the clinical trial and their motivation to continue participating in the trial. Both interviews were performed as semi-structured interviews, using an interview guide, and in both interviews, participants were asked to rank their motivation to participate on a scale from 1 to 10. Hand-written notes were taken in connection to the first interview, while the second more comprehensive interview was audio recorded and transcribed verbatim.Two out of the 21 participants in the interview dropped out of the CryoPac trial during the paclitaxel treatment period; still, both agreed to participate in the second interview. Here, they were asked about the reason for their dropout and their experience of participating in the trial.
