Early Stage Breast Cancer

Brief summary

In patients with early-stage breast cancer, chemotherapy has substantially improved survival rates for breast cancer patients. Improvements in outcomes, however, are compromised by the considerable toxicities associated with chemotherapy, most notable being neutropenia. Neutropenia is the presence of abnormally few white blood cells, leading to increased susceptibility to infection and can require hospitalization and need for intravenous antibiotics and is sometimes fatal. Febrile neutropenia can also be associated with treatment delays and dose reductions, potentially compromising treatment efficacy. Patients can receive medication to reduce the risk of febrile neutropenia, such as Neupogen (Filgrastim) as a daily injection for 5, 7, or 10 days. Since there is genuine uncertainty amongst healthcare professionals as to which administration schedule of Neupogen is better, investigators are performing a randomized study in which patients are put into a group by chance to give participants one of three standards of Neupogen daily injection. Neupogen can cost approximately $200 per injection, so if a physician prescribes 10 days for 8 cycles of treatment this can cost $16,000 compared to a 5 day prescription which would cost half this. In addition to cost savings, many patients are not able to give themselves injections on a daily basis and require nursing resources which are utilized at high-cost. This study will use an integrated consent model that involves an oral consent rather than a written informed consenting process in order to increase the number of patients who may participate while performing a study at a lower cost. While determining the optimal treatment will improve patient comfort and acceptability, using the minimal safe duration of administration may also offer cost savings.
