BackgroundFollowing the National Chemotherapy Advisory Group report, calling for better management of patients with cancer admitted acutely to hospital, Clatterbridge Cancer Centre, with Merseyside and Cheshire Cancer Network, implemented an acute oncology service (AOS) for the region's seven acute trusts.Study designWe prospectively collected data on all referrals from March 2010 to December 2012, seen by the seven local teams within the cancer network.ResultsOver 7000 patient-episodes were analyzed. We found an AOS has the greatest impact on reducing hospital stay of patients admitted with complications of cancer treatment, compared with patients presenting with cancer symptoms, or those presenting with a new cancer as an emergency. Also an AOS significantly reduces the mortality rate of patients admitted with complications of cancer treatment, compared with patients presenting with cancer symptoms, either of a known cancer or those patients presenting with a new cancer as an emergency.ConclusionsOur network establishment of an AOS has had a positive impact on the quality of care cancer patients receive, in addition to saving local trusts valuable bed days, due to the overall reduction in hospital stay. This study also highlights deficiencies in the cancer journeys of certain patients with cancer, such as patients who present with a new cancer as an emergency admission, or patients unable to be discharged due to a lack of community resources. Such analysis is important in highlighting where the AOS can concentrate resources and collaborate with other healthcare professionals, especially within the local community.

In addition to its role in bone turnover, osteoprotegerin (OPG) has been reported to bind to and inhibit Tumour necrosis factor-related apoptosis inducing ligand (TRAIL). TRAIL is produced in tumours by invading monocytes, inducing apoptosis in neoplastic cells sensitive to this cytokine. OPG production by tumour cells would therefore be a novel mechanism whereby cancer cells evade host defences and gain a growth advantage. In this study we show that OPG produced by breast cancer cells enhances tumour cell survival by inhibiting TRAIL-induced apoptosis. OPG expression by breast cancer cells (MDA-MB 436/231) grown in vitro was examined using PCR and ELISA, and the sensitivity of these cells to TRAIL was determined. The effects of OPG on TRAIL induced apoptosis was investigated by exposing MDA-MB 436 cells to TRAIL, in the presence or absence of OPG, followed by assessment of nuclear morphology. We found that the levels of OPG produced were sufficient to inhibit TRAIL-induced apoptosis, suggesting that OPG may play a role in tumour cell survival. We also examined the expression pattern of OPG in a selection of breast tumours (n=400) by immunohistochemistry, and related OPG expression to the clinico-pathological data for each tumour. OPG expression was found to be negatively correlated with increasing tumour grade. To our knowledge these results are the first to demonstrate that OPG can act as an endocrine survival factor for breast cancer cells, as well as reporting the expression patterns of OPG in a large cohort of human breast tumours.

Adjuvant trastuzumab significantly improves outcomes for patients with HER2-positive early breast cancer. The standard treatment duration is 12 months but shorter treatment could provide similar efficacy while reducing toxicities and cost. We aimed to investigate whether 6-month adjuvant trastuzumab treatment is non-inferior to the standard 12-month treatment regarding disease-free survival. This study is an open-label, randomised phase 3 non-inferiority trial. Patients were recruited from 152 centres in the UK. We randomly assigned patients with HER2-positive early breast cancer, aged 18 years or older, and with a clear indication for chemotherapy, by a computerised minimisation process (1:1), to receive either 6-month or 12-month trastuzumab delivered every 3 weeks intravenously (loading dose of 8 mg/kg followed by maintenance doses of 6 mg/kg) or subcutaneously (600 mg), given in combination with chemotherapy (concurrently or sequentially). The primary endpoint was disease-free survival, analysed by intention to treat, with a non-inferiority margin of 3% for 4-year disease-free survival. Safety was analysed in all patients who received trastuzumab. This trial is registered with EudraCT (number 2006–007018–39), ISRCTN (number 52968807), and ClinicalTrials.gov (number NCT00712140). Between Oct 4, 2007, and July 31, 2015, 2045 patients were assigned to 12-month trastuzumab treatment and 2044 to 6-month treatment (one patient was excluded because they were double randomised). Median follow-up was 5·4 years (IQR 3·6–6·7) for both treatment groups, during which a disease-free survival event occurred in 265 (13%) of 2043 patients in the 6-month group and 247 (12%) of 2045 patients in the 12-month group. 4-year disease-free survival was 89·4% (95% CI 87·9–90·7) in the 6-month group and 89·8% (88·3–91·1) in the 12-month group (hazard ratio 1·07 [90% CI 0·93–1·24], non-inferiority p=0·011), showing non-inferiority of the 6-month treatment. 6-month trastuzumab treatment resulted in fewer patients reporting severe adverse events (373 [19%] of 1939 patients vs 459 [24%] of 1894 patients, p=0·0002) or stopping early because of cardiotoxicity (61 [3%] of 1939 patients vs 146 [8%] of 1894 patients, p<0·0001). We have shown that 6-month trastuzumab treatment is non-inferior to 12-month treatment in patients with HER2-positive early breast cancer, with less cardiotoxicity and fewer severe adverse events. These results support consideration of reduced duration trastuzumab for women at similar risk of recurrence as to those included in the trial.

Development of a 24/7 acute oncology service at Clatterbridge Cancer Centre Foundation Trust. The establishment of a service providing access to a team of oncology consultants for all acute hospitals in the local cancer network is outlined. The improvements for patients with cancer, and for those attending the emergency department in particular, are outlined. 0 references
