EBV-Associated Smooth Muscle Neoplasms:Solid Tumors Arising in the Presence of Immunosuppression and Autoimmune Diseases

[摘要] Background. Epstein-Barr virus (EBV)-related smooth muscle neoplasms (SMNs) have been associated with immune dysregulation, most notably in patients who have undergone solid organ transplantation or in patients with HIV/AIDS.Objective. to report our experience with EBV-related neoplasms as well as describing the first EBV-related SMN in the setting of administration of glucocorticoids and the tumor necrosis factor inhibitor etanercept.Design.We have case reports, of minimum 3-year follow-up,2002–2005.Setting.It was held in an academic and tertiary referral cancer center.Patients. Patients are with dysregulated immunity after solid organ transplantation, HIV/AIDS, or with psoriasis after treatment with etanercept.Interventions.There were discontinuation of etanercept, right hepatic trisegmentectomy, andchemotherapy.Measurements.We use survival as a measurement here.Results. Patients who were able to withstand reduction in immunosuppression survived. Surgical resection or chemotherapy was successful in delaying progression of disease.Limitations.There was arelatively short follow-up for these slow-growing neoplasms.Conclusion. EBV-related SMNs have variable aggressiveness. While chemotherapy may slow disease progression, resection and improving the host immune status provide the best opportunity for primary tumor control.
