Standard of care of patients with Chronic Myeloid Leukemia (CML) treated in community based oncology group practices between 2001-2015 in Rhineland- Palatinate (Germany)

ABSTRACT

Background: The aim of this study was to assess retrospectively treatment and outcome of CML-patients in community based oncology practices in Germany and whether European LeukemiaNET (ELN) recommendations were followed. Method: All Ph+, BCR-ABL1+ CML-patients who were treated between 11/2001 and 12/2015 in nine oncology group practices were analyzed retrospectively. Results: Two hundred sixty patients with a median age of 60 (18­90) were analyzed. 254 (98%) were in chronic phase, 5 (2%) in accelerated and 1 (0.4%) in blast crisis. 248 patients (95%) received some form of TKI-therapy. 1st line TKI was imatinib in 197 patients (79%), 51 (21%) received a second generation TKI. 75% of TKI-therapies were monitored by PCR. Overall survival after 10 years according to Charlson comorbidity index (CCI) was CCI 2 100%; CCI 3­4 83%; CCI 5­6 52%; CCI ≥7 39%. More patients died from comorbidities (8%) than from CML (5%). Whether patients died was strongly correlated to CCI at diagnosis CCI 2 3% of patients died, CCI 3­4 16% of patients died, CCI 5­6 38% of patients died, CCI ≥ 7 42% of patients died. Conclusion: CML-patients treated in oncology group practices receive standard of care as recommended by ELN. Overall survival in routine care is comparable to international studies. Molecular monitoring should be improved (AU)
