RESUMO
BACKGROUND: Multiple myeloma (MM) is a plasma cell neoplasm, which accounts for 1-2% of cancers and approximately 17% of hematological malignancies in the United States each year. Fifty percent of patients with symptomatic MM have three or more primary care visits before being referred to a specialist, which is greater than any other cancer. A delay in the diagnosis of multiple myeloma has been shown to negatively impact the clinical course of the disease; patients with longer diagnostic intervals have been shown to experience shorter disease-free survival and higher rates of treatment-related complications. RESEARCH DESIGN AND METHODS: We performed a retrospective analysis of patients diagnosed with MM in our institution, to determine the time from the first detectable lab abnormality to the diagnosis of MM. RESULTS: We included 92 patients in this study. Fifty-two percent of patients had isolated anemia at the time of diagnosis. Twenty-nine percent of patients had a delay in diagnosis of ≥1 year, while 18% had a delay of ≥3 years. Nine patients in our cohort had anemia and an elevated serum total protein (31%). This group had the longest time to diagnosis with a median of 38 months. CONCLUSIONS: Our results did not show any difference in time to diagnosis by race, ethnicity, gender, or socioeconomic status.
