From: Identification of multiple cancer-associated myositis-specific autoantibodies in idiopathic inflammatory myopathies: a large longitudinal cohort study

Autoantibodies Patients with paralleled clinical course, numbera Patients with non-paralleled clinical course, number Total numberb
Anti-TIF1-γ 20 14 34
Anti-NXP2 2 1 3
Anti-SAE1 2 2 4
Anti-HMGCR 1 0 1
Anti-SRP 0 1 1
Anti-Jo-1 1 4 5

  1. Abbreviations: MSAs myositis specific autoantibodies
  2. aA paralleled clinical course meant that myositis emerged/deteriorated with the progression/recurrence of previously diagnosed cancers, cancer emerged with the recurrence of previously diagnosed IIMs, and/or myositis improved after removal or effective treatment of the cancer
  3. bFour patients with anti-TIF1-γ and one MSA-negative patient were lost to follow up
  4. cNegative for all of the listed MSAs
