Many patients with cancer require palliative care at some stage and the vast majority of people followed in palliative care are cancer patients. Patients with cancer are at high risk of venous thromboembolism (VTE), and this is particularly true during the advanced palliative phase when mobility is limited or absent. Patients with cancer in palliative care are at higher bleeding risk compared to non-cancer patients. ⋯ In cancer patients in advanced palliative care, the benefit/risk ratio of anticoagulation seems unfavourable with a higher haemorrhagic risk than the benefit associated with prevention of CAT recurrence and, above all, in the absence of any benefit on quality of life. For this reason, we recommend that patients should be prescribed anticoagulants on a case-by-case basis. The choice of whether to treat, and with which type of treatment, should take into account anticipated life expectancy and patient preferences, as well as clinical factors such as the estimated bleeding risk, the type of VTE experienced and the time since the VTE event.

The use of strong opioids in medical units is recurrent, mainly for analgesic purposes. The risk of occurrence of an overdose or an opioid use disorders causes very legitimate concerns for the physician, which may limit the use of opioid treatment or the adaptation of the doses necessary to relieve the patient. We provide a summary of the literature aimed at defining the indications, the adverse effects and the risks involved, the prescribing methods in order to reassure professionals and promote the safe use of these molecules.

Interstitial lung diseases (ILD) are a heterogeneous group of respiratory diseases often related to connective tissue diseases. Some patients will develop an ILD with autoimmune features without reaching the recommended criteria for autoimmune diseases. Their management is difficult because they have both features for idiopathic and connective tissue disease. ⋯ Older age at diagnosis, a pattern of usual interstitial pneumonia, and an impaired diffusing capacity for carbon monoxide have been identified as poor prognosis factors. The treatment relies on usual care for chronic respiratory diseases and is often associated with immunosuppressive and/or antifibrotic therapies. The objective of this classification is to better characterize these patients and improve their management.

Catheter-related thrombosis (CRT) is a relatively frequent and potentially fatal complication arising in patients with cancer who require a central catheter placement for intravenous treatment. In everyday practice, CRT remains a challenge for management; despite its frequency and its negative clinical impact, few data are available concerning diagnosis and treatment of CRT. In particular, no diagnostic studies or clinical trials have been published that included exclusively patients with cancer and a central venous catheter (CVC). ⋯ In symptomatic patients, venous ultrasound is the most appropriate choice for first-line diagnostic imaging of CRT because it is noninvasive, and its diagnostic performance is high (which is not the case in asymptomatic patients). In the absence of direct comparative clinical trials, we suggest treating patients with CRT with a therapeutic dose of either a LMWH or a direct oral factor Xa inhibitor, with or without a loading dose. These anticoagulants should be given for a total of at least 3 months, including at least 1 month after catheter removal following initiation of therapy.

Although all patients with cancer-associated thrombosis (CAT) have a high morbidity and mortality risk, certain groups of patients are particularly vulnerable. This may expose the patient to an increased risk of thrombotic recurrence or bleeding (or both), as the benefit-risk ratio of anticoagulant treatment may be modified. Treatment thus needs to be chosen with care. ⋯ Similarly, platelet count should be assessed prior to treatment and monitored regularly. In patients with grade 3-4, thrombocytopenia (less than 50,000platelets/μL) treatment with a LMWH at a reduced dose should be considered. For patients with CAT and low body weight, standard anticoagulant treatment recommendations are appropriate, whereas in obese patients, apixaban may be preferred.
