RESUMO
BACKGROUND: The public subsidy in Australia of bortezomib (Velcade) for untreated non-transplant multiple myeloma patients was based on the VISTA trial. AIMS: To ascertain the health outcomes of bortezomib in 'real world' transplant-ineligible elderly patients, compared to trial data. METHODS: Patient and treatment data were extracted from an oncology information system, laboratory information system and medical chart audits for three Queensland public hospitals. RESULTS: We identified 74 patients; the median age was 75 years. Our cohort comprised 47% patients who were International Staging System stage III, 45% at stage II and 8% at stage I. Patients who had comorbidities, such as cardiac disease (41%), pulmonary disease (14%), diabetes (22%), peripheral neuropathy (14%) and other comorbidities (41%) at baseline were included. The common regimens prescribed were VMP, CVD and VD, and most patients (n = 73) received bortezomib on a once-weekly or twice-a-week basis. The overall response rate was 81%. Half (53%) of the patients did not complete their planned therapy due to toxicity (30%), suboptimal response or disease progression (15%), or death on treatment (8%). Overall survival was 40.7 months and progression free survival was 17.7 months. CONCLUSIONS: Our patients were older, had worse disease characteristics and more comorbidities than patients in the VISTA trial. While response rates were similar, survival outcomes appeared worse. Bortezomib-based treatment in the real world setting still carries a high risk of toxicity in the elderly population.

BACKGROUND: Chronic lymphocytic leukaemia (CLL) is the most common lymphoproliferative disease in Australia. Improvements in the understanding of this disease have led to drastic changes in regards to diagnosis, management and prognosis. OBJECTIVE: The aim of this article is to give an updated approach to the diagnosis, investigation, monitoring and new treatments of CLL. DISCUSSION: With the advent of new medications and improved investigations to predict outcomes, CLL has now become a chronic disease that requires long-term monitoring by haematologists and general practitioners (GPs).

Objectives: We aimed to externally validate Lilleness' et al. Boston University (BU) prognostic score that replaced NT-proBNP with brain natriuretic peptide (BNP), which will allow centres without access to NT-proBNP to accurately stage and prognosticate AL amyloidosis. Patients/methods: Forty-four were identified that had BNP, NTpro-BNP and TnI taken simultaneously, with a mean follow up of 7.3 years. Median age of the 44 patients was 67 years and 27% were female, with 61% having cardiac involvement, and 61% having renal involvement. Results: Using the BU BNP-based staging system, we identified 12/44 (27%) of patients as stage I, 18/44 (41%) of patients as stage II and 14/44 (31%) of patients as stage III. This correlated closely with stratification via the Mayo score, with only one patient miscategorised (97.7% agreement, k = 0.98). Median overall survival for our BU stage I was not reached, stage II was 40 months and stage III was 5 months (long rank p = .0012). Mayo 2004 median overall survival was identical for stages I, II and III. Conclusion: We have provided external validation of the BU staging system, a novel prognostic scoring system incorporating BNP, instead of NT-proBNP, for AL amyloidosis.

BACKGROUND: Multiple myeloma is an uncommon haematological cancer of plasma cells. Improvements in understanding of this disease have lead to drastic changes regarding diagnosis, management and its prognosis. OBJECTIVE: The aim of this article is to provide a concise update regarding the current management of myeloma in Australia, and important management issues for general practitioners. DISCUSSION: With the advent of new treatments, the outcomes of myeloma have changed drastically in the past decade, and it is now a disease that requires long-term monitoring by both haematologists and general practitioners.
