RESUMEN
AIMS: There is a scarcity of data regarding medical hospitalizations for breast cancer. The aim was to determine whether the burden of inpatient care for breast cancer was declining. METHODS: A retrospective study was conducted of all admissions to a single medical oncology inpatient unit in 1996 and 2006 related to the treatment of breast cancer. The total number of hospitalizations, patients' length of stay in hospital, clinical indications for hospitalization and utilization of inpatient services were determined. Data analysis involved pairwise comparisons between the cohorts. RESULTS: The total number of breast cancer hospitalizations was similar in 1996 and 2006. However, the number of hospitalizations for adjuvant treatment complications was 50% lower in 2006, attributable to a lower rate of chemotherapy-associated febrile neutropenia. Acute clinical problems necessitating inpatient care differed between 1996 and 2006. Fewer hospitalizations for symptomatic hypercalcemia, uncontrolled pain and chemotherapy toxicity were required in 2006 but a significant increase was seen in central nervous system complications. Recent practice involved greater inpatient consultation of other medical and surgical teams. There was a trend towards a shorter duration of admissions in 2006 in both adjuvant and metastatic patients. CONCLUSION: Although total annual breast cancer admission numbers and length of stay did not change significantly, hospitalization for treatment-related complications was less frequent in 2006. The clinical manifestations of metastatic breast cancer appear to be changing, and in our institution are being managed with broader multidisciplinary care.
