Delirium is a frequent neurocognitive complication in patients with cancer, particularly in patients with advanced-stage disease (in whom a combination of factors might trigger an episode) and in patients with a high degree of predisposing vulnerability, such as the elderly or patients with dementia. The communicative impediments associated with delirium generate distress for the patient and their family, and substantive challenges for health-care practitioners, who might have to contend with agitation, and difficulty in assessing pain and other symptoms. ⋯ Although delirium is ominously associated with the terminal phase of life, part or complete reversal can be possible depending on the nature of the precipitating factors, and on whether investigation and treatment of these factors is consistent with the established goals of care. Pharmacological treatment for symptom control is indicated for most patients with delirium, and antipsychotics are the drugs of choice, but some patients with refractory and nonreversible delirium can require continuous deep sedation with agents such as midazolam.

The results of several clinical trials in metastatic colorectal cancer presented in 2014 will influence clinical practice. These findings include definitive data from phase III trials comparing bevacizumab and cetuximab-based therapy in the first-line, studies elucidating the value of maintenance therapy after induction treatment, and data on new agents in this disease.

Although the majority of patients with breast cancer have clinically negative axillary nodes at preoperative assessment, around 15-20% of these women will have metastatic disease within the lymph nodes at operative sentinel node biopsy, and additional selective treatment to the axilla might be required. Local treatment to the axilla can include axillary node clearance or axillary radiotherapy. ⋯ We review the evidence base for management of the axilla after detection of a positive sentinel node, discuss the evidence for why micrometastatic disease requires systemic but not axillary therapy, and present data suggesting that axillary irradiation for macrometastases gives equivalent control to axillary node clearance, but causes less morbidity such as lymphoedema. Ongoing trials will confirm whether any further therapy can be omitted for all patients with low volume, sentinel-node macrometastases.

Patients with cancer frequently suffer from debilitating physical symptoms and psychological distress, particularly at the end of life. Interventions to help alleviate these problems are often complex and multifactorial. Palliative care services and therapeutic interventions have developed in a variable manner, often with limited evaluation of clinical effectiveness and affordability, resulting in a relatively weak evidence base. ⋯ It has been shown that many patients with cancer wish to die at home. We discuss the factors that contribute to the place of death, including environmental factors, disease-specific issues, and the availability of resources. There has been a recent upward trend in the number of patients with cancer who die in their preferred place of care, and important contributors--such as community palliative care, advance care planning, and improvements in palliative care services as a result of robust research studies--are considered.

Circulating blood biomarkers promise to become non-invasive real-time surrogates for tumour tissue-based biomarkers. Circulating biomarkers have been investigated as tools for breast cancer diagnosis, the dissection of breast cancer biology and its genetic and clinical heterogeneity, prognostication, prediction and monitoring of therapeutic response and resistance. ⋯ As the scope of breast cancer intratumour genetic heterogeneity unravels, the development of robust and standardized methods for the assessment of circulating biomarkers will be essential for the realization of the potentials of personalized medicine. In this Review, we discuss the current status of blood-born biomarkers as surrogates for tissue-based biomarkers, and their burgeoning impact on the management of patients with breast cancer.
