| Popis: | 123 Background: The commonly used adjuvant chemotherapy regimens for early breast cancer include 5-fluorouracil, epirubicin, cyclophosphamide and docetaxel (FEC-D), docetaxel and cyclophosphamide (TC), doxorubicin and cyclophosphamide with or without paclitaxel and/or herceptin (AC combination) and docetaxel, carboplatin and trastuzumab (TCH). Hematologic toxicity from these regimens can be life threatening as well as cause significant morbidity for the patient and major costs to the health system. Granulocyte colony stimulating factor (GCSF) is frequently used to try and reduce these complications. In Australia, GCSF is funded for use as primary prophylaxis with docetaxel in combination with an anthracycline and cyclophosphamide. Secondary prophylaxis is available only after demonstration of prolonged severe neutropenia or an episode of febrile neutropenia (FN). Methods: Patients treated with adjuvant chemotherapy for early breast cancer at Gold Coast Hospital, Qld, Australia from February 2010 to February 2012 were identified. Patient charts were reviewed for incidence of neutropenia (neutrophil count 9/L), FN (temp ≥38°C), dose reductions or delays and use of GCSF. Results: 102 patients were treated over this time. Incidence of neutropenia, FN and use of GCSF are summarised below. 30 patients receiving FEC-D had a dose delay or reduction with the majority due to non-haematologic toxicities. 96% patients completed 6 cycles of treatment. Of the patients with FN in the TC group, half had received primary GCSF. No patients who were given primary GCSF experienced a dose delay. Similar trends were observed in the other treatment groups. Conclusions: Our results show that patients receiving FEC-D along with GCSF had lower rates of neutropenia and hospitalisations. Rates of neutropenia and dose delay are higher in the other groups. FEC-D is the most commonly used regimen in our institution likely due to the availability of GCSF. [Table: see text] |
