RESUMO
PURPOSE: A large number of AML patients present with infection at the time of initial presentation in Indian settings. There is lack of published data on the proportion of patients with infection at initial presentation and its impact on induction mortality. METHODS: A retrospective audit of patients with newly diagnosed AML more than 14 years of age, who underwent standard induction chemotherapy between the periods of January 2011 to December 2018, was done. Infection at presentation if any was documented. Induction mortality was defined as death happening within 28 days of starting induction chemotherapy. RESULTS: Among a total of 315 cases of AML, 96 (30%) patients underwent induction chemotherapy with 7 + 3 regimen. Documented infection at baseline was present in 30 (31%) of patients. Another 10 patients had fever at the time of presentation but without any documented infection focus. Fifteen patients died within 4 weeks of induction amounting to induction mortality of 15.6%. Induction mortality was 28% among patients with infection at baseline compared with 7% without baseline infections (P = 0.01). CONCLUSION: Around 40% of patients had fever at the time of presentation, and 31% had documented infections. Baseline infections led to increase in induction mortality. We would like to propose that infection at baseline is to be considered as one of the potential variables in the predictive scoring system for induction mortality in developing countries.
