Background: Febrile neutropenia (FN) and myelosupression remain a challenging on-cologic medical emergency and dose limiting toxicity associated with chemotherapy for cancers. Various factors are known to affect the outcomes for patients diagnosed with FN. Electrolyte abnormalities have commonly been observed, but the real incidence and their impact has been only scarcely studied in literature. Methods: This was a prospective, observational study. A total of two hundred and fifteen (215) patients admitted between January 2007 and August 2008 were included. Analysis of data was made using SPSS version 16.0. Toxicity profile was graded according to CTC version 3.0. Results: Almost equal number of FN was observed in both solid tumors and hematological cancers with almost equal gender distribution. Of all 83.5% patients demonstrated some electrolyte abnormalities. All grades combined, hypokalemia was seen in 48% of patients, with 51.4% having grade I, 33.3% grade III and 15.2% G IV (life threatening) hypokalemia. Hypo-natremia of all grades was seen in 67.9% patients, of them 60.3% had Grade I, 33.3% grade III and 0.7% patients had grade IV hyponatremia. Hypomagnesaemia (70 patients assessed) was seen in 54.3% patient, 94.7% having grade I decline. Average length of stay for patients who received IV electrolyte replacement was 6.3 days compared to 4.9 days in those who did not. Out of 90 patients who required special care unit 75 had electrolyte abnormalities, of 15 patients who expired 13 had electrolyte abnormalities Conclusion: This analysis, which is first of its kind, suggests that decline in electrolyte levels is frequently observed in patients presenting with FN. These abnormalities can have independent negative impact on the outcome for such patients. Special attention should be paid to electrolyte imbalance right from the outset.
