Real-world use of granulocyte colony-stimulating factor in ambulatory breast cancer patients: a cross-sectional study.

PURPOSE: To prevent febrile neutropenia (FN), European Organisation for Research and Treatment of Cancer (EORTC) guidelines recommend primary prophylaxis with granulocyte colony-stimulating factors (PPG) for patients at high risk (≥ 20%) of FN. In Belgium, the use of PPG is restricted by specific reimbursement criteria. The impact of these criteria on PPG use and adherence to guidelines is unknown. METHODS: This multicentre, cross-sectional, observational study aimed to describe PPG use by FN risk category in breast cancer patients who were scheduled to receive myelosuppressive chemotherapy in outpatient clinics in Belgium during a 2-week period between 13 October and 12 December 2014. RESULTS: In total, 490 patients were enrolled. Median age was 57.0 years. Based on their chemotherapy regimen, 53.9, 5.1 and 41.0% of patients were at a low, intermediate and high risk of FN, respectively. Overall, 39.8% of patients received PPG (17.0, 12.0 and 73.1% of those receiving low-, intermediate- and high-risk regimens, respectively). In the high-risk category, PPG was used in 89.9% of dose-dense and in 25.0% of classical chemotherapy regimens. PPG use was adherent to EORTC guidelines in 75.3% of patients (30.6% appropriate use, 44.7% appropriate non-use). EORTC guidelines would recommend PPG use in 46.1% of this study population (n = 226), and its use was reimbursable in Belgium in 76.1% of these patients (n = 172), but only 66.4% of them received PPG (n = 150). CONCLUSIONS: Both Belgian reimbursement criteria and physician decision-making led to a proportion of patients for whom PPG treatment was recommended but finally not receiving it.

Information needs about palliative care and euthanasia: A survey of patients in different phases of their cancer trajectory.

OBJECTIVE: We assessed information provision and information needs about illness course, treatments, palliative care and euthanasia in cancer patients. METHODS: Cancer patients consulting a university hospital (N=620) filled out a questionnaire. Their cancer related data were collected through the treating oncologist. This study is performed in Belgium, where "palliative care for all" is a patient's right embedded in the law and euthanasia is possible under certain conditions. RESULTS: Around 80% received information about their illness course and treatments. Ten percent received information about palliative care and euthanasia. Most information about palliative care and euthanasia was given when the patient had a life expectancy of less than six months. However, a quarter of those in earlier phases in their illness trajectory, particularly those who experienced high pain, fatigue or nausea requested more information on these topics. CONCLUSION: Many patients want more information about palliative care and euthanasia than what is currently provided, also those in an earlier than terminal phase of their disease. PRACTICE IMPLICATIONS: Healthcare professionals should be more responsive, already from diagnosis, to the information needs about palliative care and possible end-of-life decisions. This should be patient-tailored, as some patients want more and some patients want less information.

Initial assessment of tumor tracking with a gimbaled linac system in clinical circumstances: a patient simulation study.

PURPOSE: To have an initial assessment of the Vero Dynamic Tracking workflow in clinical circumstances and quantify the performance of the tracking system, a simulation study was set up on 5 lung and liver patients. METHODS AND MATERIALS: The preparatory steps of a tumor tracking treatment, based on fiducial markers implanted in the tumor, were executed allowing pursuit of the tumor with the gimbaled linac and monitoring X-rays acquisition, however, without activating the 6 MV beam. Data were acquired on workflow time-efficiency, tracking accuracy and imaging exposure. RESULTS: The average time between the patient entering the treatment room and the first treatment field was about 9 min. The time for building the correlation model was 3.2 min. Tracking errors of 0.55 and 0.95 mm (1σ) were observed in PAN/TILT direction and a 2D range of 3.08 mm. A skin dose was determined of 0.08 mGy/image, with a source-to-skin distance of 900 mm and kV exposure of 1 mAs. On average 1.8 mGy/min kV skin dose was observed for 1 Hz monitoring. CONCLUSION: The Vero tracking solution proved to be fully functional and showed performance comparable with other real-time tracking systems.
