paraneoplastic syndrome

Oncology A co-morbid condition due to the indirect–remote or 'biologic' effects of malignancy, which may be the first sign of a neoplasm or its recurrence; PSs occur in > 15% of CAs, are caused by hormones, growth factors, biological response modifiers, and other as-yet unidentified factors, and may regress with treatment of the primary tumor. See Ectopic hormone.
