Hinduja A et al: Rosai-Dorfman disease manifesting as intracranial and intraorbital lesion. A superficial scalp mass that contained several hyperintense foci suggesting calcifications was incidentally noted. The masses are incompletely surrounded by fat and isointense with brain and muscle.

In a population-based sample of all patients with glioma diagnosed in Victoria from 1998 to 2000, the median survival was 9. This could include issues such as patient characteristics and /or specific circumstances that patients would have to satisfy in order to access the service. Adjuvant whole brain radiotherapy and chemotherapy post surgery has been shown to improve survival. Indicate if there is evidence for the population who would benefit from this service i. If appropriate provide a table summarising the population considered in the evidence. The study included patients aged 18–72 years with suspected newly diagnosed, untreated malignant glioma and who were eligible for surgery according to the study surgeon. Provide details on the expected utilisation, if the service is to be publicly funded. In 2010 there were 1,680 incident cases of brain tumour in Australia (Australian-specific age standardised incidence rate 7. The total patient population would be slightly higher than this with the inclusion of patients with recurrent tumours. This medicine is administered orally, at least three hours before the induction of anaesthesia (recommended dose of 20 mg/kg of body weight) (Gliolan Product Information). With blue light the tumour can be seen as pink fluorescence in an area that looked relatively normal with white light. This enables the surgeon to see the tumour more clearly during brain surgery and to remove it more accurately, sparing healthy brain tissue. If the service is for investigative purposes, describe the technical specification of the health technology and any reference or “evidentiary” standard that has been established. The viable malignant glioma tumoural tissue is visualised as an intense red fluorescence. This value was defined as the percentage of patients with positive identification of tumoural cells in all biopsies conducted in areas of strong and weak fluorescence. The Gliolan product information provides details of interactions, use in specific patients, contra-indications, precautions, and adverse events. Indicate whether the service includes a registered trademark with characteristics that distinguish it from any other similar health technology. There are no other products registered for the use in fluorescence guided resection of high grade glioma. Indicate the proposed setting in which the proposed medical service will be delivered and include detail for each of the following as relevant: inpatient private hospital, inpatient public hospital, outpatient clinic, emergency department, consulting rooms, day surgery centre, residential aged care facility, patient’s home, laboratory. Where the proposed medical service will be provided in more than one setting, describe the rationale related to each. This could include details such as frequency of use (per year), duration of use, limitations or restrictions on the medical service or provider, referral arrangements, professional experience required. The reconstituted solution is physically-chemically stable for 24 hours at 25C, however the product information states that Gliolan should be used within four hours of reconstitution. Specialised Therapeutics Australia provides neurosurgeons with a distance learning based training program. In addition to these benefits, it is widely accepted that there is a relation between the extent of resection, and survival, in order to provide the best starting platform for adjuvant therapy (Australian Cancer Network 2009). The retrospective study of Lacroix and colleagues (2001), which involved 416 patients with glioblastoma multiforme, identified age, Karnofsky functional status, the degree of necrosis in pre-surgery magnetic resonance imaging, and extent of resection as predictive factors of survival. The prospective study from Albert and colleagues (1994), which included 60 patients with high grade glioma, concluded that patients with a residual tumour had a death risk factor that was six times higher in comparison to patients without residual tumour after surgery. Patients with a complete resection were compared with patients with an incomplete resection, whilst controlling for factors such as age, tumour location and Karnofsky functional status. This re-analysis confirmed the association between the resection degree and survival (Stummer 2008). The treatment of relapses depends on the extension of disease and the patient’s clinical condition. In case of a local relapse, a new surgery is recommended, if possible, either with or without placement of chemotherapy implants. After surgery, patients with a poor functional status only receive supportive treatment, whilst patients with a better clinical condition undergo chemotherapy and/or re-radiation. For recurrence of diffuse pattern or multiple lesions, the therapeutic options are supportive treatment in patients with poor functional status, and systemic chemotherapy and/or surgery for symptomatic relief. These protocols are consistent with the earlier Australian guidleines which recommend concurrent radiotherapy and chemotherapy followed by adjuvant chemotherapy, finding that it provides a significant improvement in median and two-year survival in patients with (Australian Cancer Network 2009).
