Gupta, S., Singh, P.K., Bhatt, M.L., Pant, M.C., Gupta, R., & Negi, M.P. (2010). Efficacy of granulocyte colony stimulating factor as a secondary prophylaxis along with full-dose chemotherapy following a prior cycle of febrile neutropenia. Bioscience Trends, 4, 273–278.
The purpose of the study was to evaluate the feasibility and efficacy of G-CSF secondary prophylaxis in patients with solid tumors undergoing chemotherapy.
Patients in the study required IV antibiotics filgrastim 300 mg per day subcutaneously starting 24–30 hours after the last chemotherapy dose in a subsequent cycle. A total of 8–9 alternate day doses were given. If no other dose limiting toxicity was seen, patients received full chemotherapy dosing with filgrastim support for following treatment cycles. Duration of hospital stay, days on antibiotic therapy, incidence of fever, time to resolve fever, dose reductions or delays, neutrophil recovery time, and incidence of adverse events were recorded. Results compared to findings in the same patients during the previous chemotherapy cycle.
Single-site location in India
Active antitumor treatment
Prospective, single group, observational study
No specific measure definitions were provided.
Neutrophil recovery time, duration of fever, duration of antibiotics and duration of hospitalization, cycle delays, and chemotherapy dose reductions declined with each course of chemotherapy. The decrease in all measures was significant across four treatment cycles (p < 0.01).
Study findings provide some support the use of colony-stimulating factor as secondary prophylaxis in patients receiving myelosuppressive chemotherapy. A number of study limitations limit the strength of these findings.
This study provides limited evidence supporting the use of colony-stimulating factors as secondary prophylaxis in patients receiving chemotherapy. CSF was given every other day in this trial, adding to the body of evidence in which the frequency of administration varies. Secondary prophylaxis can play an important role in sustaining the treatment dosages of chemotherapy cycles.
