BACKGROUND: Chronic myelomonocytic leukemia (CMML) is a rare and likely underdiagnosed hematologic malignancy. Due to its rarity and nuances in diagnosis, many patients are referred to tertiary referral centers, although many continue to be cared for in the community setting. Given discrepancies in outcomes based on facility type in related myeloid malignancies, we hypothesized that CMML patients treated at academic centers may have improved survival as compared to patients treated at nonacademic centers (NACs).
PATIENTS AND METHODS: Using the National Cancer Database (NCDB), we identified 6290 patients with CMML and collected data on demographics, comorbidities, treatment, and survival. We also performed a propensity matched analysis to control for baseline differences.
RESULTS: We found that patients at academic centers had higher median overall survival (OS) (17.7 months vs 14.7 months) and 5-year OS (19.1% vs 15.3%) than patients at NACs. In addition, patients treated at an academic center were also more likely to receive hematopoietic stem cell transplant as compared to those treated at NACs. Time to treatment initiation was overall similar between academic and NACs.
CONCLUSION: Our study of one of the largest available datasets of CMML patients supports the importance of referring CMML patients to academic centers upon diagnosis to optimize outcomes in this rare hematologic malignancy.
