Impact of 1q gains on treatment outcomes of patients with newly diagnosed multiple myeloma in a real-world Swedish population receiving modern treatment
Background: Amplification of 1q (amp(1q); ≥4 1q copies) has repeatedly been reported to predict a worse outcome in multiple myeloma (MM), whereas the impact of gain of 1q (gain(1q); three 1q copies) is less clear. Methods: We investigated survival of MM in relation to amp(1q) and gain(1q) by retrospectively analysing 346 consecutively newly diagnosed MM (NDMM) patients. Of these, 62 (18%) had amp(
