A comparative analysis of remission rates and length of stay of patients with de-novo AML and patients with AML with underlying MDS in a community hospital setting

Acute Myeloid Leukemia (AML) is a type of cancer that affects the process of hematopoiesis. In individuals affected with AML, normal blood cells do not develop into red blood cells, white blood cells, and platelets, leading to symptoms such as anemia, neutropenia, and thrombocytopenia. The prognosis of AML is affected by multiple factors including: the genetic make-up of the leukemic cells, age of the affected individual, and underlying blood disorders such as myelodysplastic syndrome (MDS). MDS affects the development of stem cells into red blood cells, white blood cells, and platelets. Due to their clinical heterogeneity, AML and MDS continue to be a challenge that should be investigated in the community hospital setting. Remission rates between patients diagnosed with de-novo AML and patients diagnosed with AML with MDS were compared in a community hospital setting following induction therapy using a retrospective study design. Length of stay between patients diagnosed with de-novo AML and patients diagnosed with AML with MDS was compared during induction therapy. The association of age at diagnosis and number of chromosomal abnormalities to remission status was evaluated in each disease group. The association of blood transfusion requirements and neutropenic fever to length of stay was evaluated in each disease group. There were no statistically significant differences found between disease groups with respect to remission rates and length of stay. There were no statistically significant associations found between blood transfusion requirements and neutropenic fever in each disease group. There was an association found between age at diagnosis and remission status in patients diagnosed with AML with MDS. This indicates that older patients with AML with MDS are less likely to benefit from therapy and achieve complete remission. It is important to consider the small sample size, rare nature of the disease, and other variables that could have contributed to trends seen in the study population. The impact of predictors such as growth factor use and incidence of fungal infections should be investigated in future studies with AML patients. Considering these factors will allow for the development of targeted therapies and mechanisms against drug resistance for affected individuals.
