Expert UK consensus on the definition of high risk of recurrence in HER2-negative early breast cancer: A modified Delphi panel.

BACKGROUND: There is currently no standardised definition for patients at high risk of recurrence of human epidermal growth factor receptor 2 (HER2)-negative early breast cancer (eBC; stages 1-3) after surgery. This modified Delphi panel aimed to establish expert UK consensus on this definition, separately considering hormone receptor (HR)-positive and triple-negative (TN) patients. METHODS: Over three consecutive rounds, results were collected from 29, 24 and 22 UK senior breast cancer oncologists and surgeons, respectively. The first round aimed to determine key risk factors in each patient subgroup; subsequent rounds aimed to establish appropriate risk thresholds. Consensus was pre-defined as ≥70% of respondents. RESULTS: Expert consensus was achieved on need to assess age, tumour size, tumour grade, number of positive lymph nodes, inflammatory breast cancer and risk prediction tools in all HER2-negative patients. There was additional agreement on use of tumour profiling tests and biomarkers in HR-positive patients, and pathologic complete response (pCR) status in TN patients. Thresholds for high recurrence risk were subsequently agreed. In HR-positive patients, these included age <35 years, tumour size >5 cm (as independent risk factors); tumour grade 3 (independently and combined with other high-risk factors); number of positive nodes ≥4 (independently) and ≥1 (combined). For TN patients, the following thresholds reached consensus, both independently and in combination with other factors: tumour size >2 cm, tumour grade 3, number of positive nodes ≥1. CONCLUSIONS: The results may be a valuable reference point to guide recurrence risk assessment and decision-making after surgery in the HER2-negative eBC population.

The frequency and severity of capecitabine-induced hypertriglyceridaemia in routine clinical practice: a prospective study.

BACKGROUND: Capecitabine is known to rarely cause raised serum triglycerides (TG). In our centre, several patients receiving capecitabine developed raised TG levels corresponding to the 'very high risk' category for potentially serious acute pancreatitis. METHODS: A fasting blood lipid screening protocol was introduced into clinical practice for patients receiving capecitabine. Patients with TGs >5 mmol l(-1) were treated and followed up. An 18-month prospective audit was performed to establish the incidence and severity of capecitabine-induced hypertriglyceridaemia (CIHT). RESULTS: A total of 304 patients received capecitabine for colorectal cancer between January 2008 and June 2009. Of these, 212 patients (70%) were screened and 8 (3.7%) developed clinically significant hypertriglyceridaemia requiring lipid-lowering therapy. Two of the eight patients had diabetes and one had pre-existing dyslipidaemia. One suffered cerebral infarction during chemotherapy. There were no cases of acute pancreatitis. Follow-up showed that serum TGs safely and rapidly returned to normal with appropriate treatment without discontinuation of capecitabine. CONCLUSIONS: This is the first prospective study evaluating CIHT. These results suggest that it should be classed as a 'common' undesired effect of capecitabine. Despite this, the incidence does not justify routine screening in all patients. Targeted screening in those with diabetes or pre-existing hyperlipidaemia is recommended, together with adoption of a clear management policy.
