Neoplastic and non-neoplastic complications of solid organ transplantation in patients with preexisting monoclonal gammopathy of undetermined significance.

Monoclonal gammopathy of undetermined significance (MGUS) occurs in 3-7% of the elderly population, with higher prevalence in renal failure patients, and is associated with a 25-fold increased lifetime risk for plasma cell myeloma (PCM), also known as multiple myeloma. Using the California State Inpatient, Emergency Department, and Ambulatory Surgery Databases components of the Healthcare Cost and Utilization Project (HCUP), we sought to determine whether patients with MGUS who undergo solid organ allograft (n = 22,062) are at increased adjusted relative risk (aRR) for hematologic malignancy and other complications. Among solid organ transplant patients, patients with preexisting MGUS had higher aRR of PCM (aRR 19.

Management of Elderly Patients with Plasma Cell Myeloma.

Plasma cell myeloma (PCM) is a hematologic malignancy that primarily affects the elderly. Approximately two-thirds of patients are aged 65 years or older at diagnosis. Major advances in testing, treatment, and supportive care have resulted in substantial improvement in overall survival in younger, standard-risk, PCM patients over the past 3 decades.
