Study in JNCCN Identifies Significant Factors for Reducing the Risk of Immunosuppression and Fever in People Being Treated with Chemotherapy
Researchers find the timing and length of use for corticosteroids has a particularly strong impact on the likelihood of severe, life-threatening adverse events for people with cancer
PLYMOUTH MEETING, Pa., Oct. 30, 2018 /PRNewswire/ -- New research in the October 2018 issue of JNCCN—Journal of the National Comprehensive Cancer Network identifies risk factors for chemotherapy-induced febrile neutropenia (FN) —a dangerously low white blood cell count, which increases the risk of serious infection and fever. The study was led by Chun Rebecca Chao, PhD, of the Kaiser Permanente Southern California Department of Research & Evaluation, with the intention of learning how to reduce the number of patients who experience this serious and life-threatening side effect in the future.
"Febrile neutropenia is life threatening and often requires hospitalization," explained Dr. Chao. "Furthermore, FN can lead to chemotherapy dose delay and dose reduction, which in turn negatively impacts anti-tumor efficacy. However, it can be prevented if high-risk individuals are identified and treated prophylactically."
The researchers studied 15,971 patients who were diagnosed with non-Hodgkin lymphoma, breast, lung, colorectal, ovarian, or gastric cancer and treated with myelosuppressive chemotherapy1 at Kaiser Permanente Southern California between the years 2000 and 2009. Of those, 4.3% developed FN in the first chemotherapy cycle. The study's authors found that longer term use and more recent use of corticosteroids appeared to increase the risk of FN the most, leading to three and two times the risk, respectively. Certain dermatologic and mucosal conditions (including gastritis, dermatitis, and psoriasis), as well as the use of intravenous (IV) antibiotics prior to chemotherapy were also associated with higher risk of FN during the first chemotherapy cycle.
"One way to reduce the incidence rate for FN could be to schedule prior corticosteroid use and subsequent chemotherapy with at least two weeks between them, given the magnitude of the risk increase and prevalence of this risk factor. Physicians should also consider which patients are at higher risk of FN, as identified by this study, when making decisions about using prophylactic treatment like granulocyte-colony stimulating factor (G-CSF)," said Dr. Chao.
"Identifying those at higher risk for infectious complications is a priority, in order to prevent associated complications for those undergoing treatment for cancer, especially cytotoxic therapy, as denoted in the NCCN Guidelines® for Prevention and Treatment of Cancer-Related Infections," said Lindsey Robert Baden, MD, Dana-Farber Cancer Institute, Chair of the Panel. "In this retrospective study by Dr. Chao and colleagues, risk factors for febrile neutropenia in patients with NHL and solid tumor malignancies are assessed. Corticosteroid use and selected dermatologic and mucosal conditions are found to be associated with developing FN. It will be important for these observations to be confirmed and the time frame of risk clearly defined in order to facilitate generalizability."
The research team was surprised to find a lack of association between prior or concurrent radiation therapy and FN, since radiation has been linked to bone marrow suppression2. However, they did not account for radiation field or dose, and believe more comprehensive evaluation is needed. They also found no clear association between oral antibiotic use and FN risk. The results suggest IV antibiotics may have a more profound impact on the balance of bacterial flora and other immune functions, though it is also possible that patients who received antibiotics intravenously rather than orally were generally sicker and more prone to severe infection.
