title: Serious neutropenia following neoadjuvant chemotherapy for locally advanced breast cancer: A case report.
abstract: Neoadjuvant chemotherapy has been widely used in patients with locally advanced breast cancer (LABC) to increase the chance of breast conservation. Among the most active adjuvant chemotherapy regimens, doxorubicin and cyclophosphamide are the most common drugs used for breast cancer in adjuvant and advanced settings, and taxanes are added to neoadjuvant regimens to improve the pathological complete response rates. However, chemotherapy is often associated with a variety of acute and long-term side effects, and neutropenia is one of the most common chemotherapy-associated toxicities. Lethal neutropenia is rarely reported in clinics. The present study reports the case of a patient with LABC that received 1 cycle of neoadjuvant chemotherapy [intravenous docetaxel (75 mg/m2), pirarubicin (45 mg/m2) and cyclophosphamide (500 mg/m2) on day 2 in 3-weekly intervals] and succumbed to neutropenia and subsequent multiple organ dysfunction syndrome. The present study suggests that neutropenia may be associated with significant mortality if not managed appropriately. Based on the findings of the present study, individual chemotherapy regimens, dosing schedules, effective methods of the prevention and management of neutropenia, and the management of the discharged patient require additional consideration.
