Brief summary
Investigation of which patients treated with bortezomib that have increased risk of developing peripheral neuropathy.
Detailed description
The study aims to include 20 patients with multiple myeloma that are initiating bortezomib treatment. The patients must follow their normal treatment cycles while getting blood drawn during their treatment period however maximal 9 cycles. Blood is dawn before treatment initiation and approximately once per cycle in order to measure neurofilament light chain (NFL) before and during treatment. The primary outcome is to relate the level of NFL during treatment with the level at baseline and as a secondary outcome to relate the level of NFL to the cumulative dose of bortezomib.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Level of plasma neurofilament light chain | Baseline (before treatment initiation) | Plasma neurofilament light chain before treatment with bortezomib. (Cycle length can vary). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Level of plasma neurofilament relative to cumulative dose of bortezomib | From cycle 1 (each cycle is often between 3-6 weeks) and forward, maximum 9 cycles in total. An average of 1 year. | Plasma neurofilament light chain relative to the cumulative dose of bortezomib in patients. |
| Degree of peripheral neuropathy | From cycle 1 (each cycle is often between 3-6 weeks) and forward, maximum 9 cycles in total. An average of 1 year. | Using questionnaire Chemotherapy-induced peripheral neuropathy 20 (CIPN20), grading |
