Popis: Docetaxel-based chemotherapy regimens have substantially improved survival and recurrence rates for cancer patients. Safety profile of docetaxel regimens includes toxicities, particularly a high risk of neutropenia and febrile neutropenia. Granotax was a prospective, open label, multicentre, national phase IV study that evaluated the incidence and severity of neutropenia in adult patients with solid tumors being treated with a docetaxel-based regimen while receiving the GCSF lenograstim. Among the 394 enrolled patients the incidence of grade 3-4 neutropenia was 16.2% and of febrile neutropenia was 1.5%, far lower than the reported 85–100% and 30–40% incidence without G-CSFs. A total of 68 patients (17.3%) were reported to have experienced at least one grade 3-4 adverse event during the study. Two (0.5%) patients and 32 (8.1%) patients had dose delayed due to febrile neutropenia and neutropenia, respectively. Four (1.0%) patients and 32 (8.1%) patients had a dose changed due to febrile neutropenia and neutropenia, respectively. The low incidence of adverse effects and chemotherapy dose changes, delays, and withdrawals supports the use of lenograstim as effective primary prophylaxis in South African patients being treated with a docetaxel-based regimen. Furthermore, lenograstim may increase the patient’s exposure to chemotherapy allowing patients to receive optimal dosing and duration of treatment, benefitting survival.
