GENERAL PRINCIPLES OF PALLIATIVE CARE
ASCO recommendations on palliative care in patients with advanced cancer (November 2016)
In response to increasing evidence from randomized trials that early palliative care offers benefits in terms of quality of life, mood, end-of-life care, and possibly even survival, an updated provisional clinical opinion from the American Society of Clinical Oncology (ASCO) now recommends integrating dedicated palliative care services into the care of inpatients and outpatients with advanced cancer early in the disease course, concurrent with active treatment . Essential components of palliative care may include symptom, distress, and functional status management; clarification of treatment goals; assistance with medical decision making; coordination with other care providers; and assessment and support of coping needs. (See "Benefits, services, and models of subspecialty palliative care", section on 'Rationale for palliative care'.)
Palliative care consultation for families of patients in the intensive care unit (August 2016)
Post-intensive care syndrome-family (PICS-F) is a term given to family members who have been affected physically and psychologically during the intensive care unit (ICU) stay of critically ill patients. Therapeutic measures for PICS-F are poorly studied. One multicenter randomized trial examined the impact of a palliative care-led consultation for surrogate decision-makers of critically ill patients in the ICU who were unlikely to wean from mechanical ventilation . Compared with routine family meetings conducted by the ICU team, palliative care-led consultation did not reduce symptoms of anxiety or depression of family members and may have increased symptoms of posttraumatic stress disorder. However, limitations of this study include possible inadequate "dosing" of the intervention (on average, 1.4 encounters per family and physician presence at only 9 percent of meetings), leaving the possibility that more aggressive and supportive interventions may have different outcomes. (See "Post-intensive care syndrome (PICS)", section on 'Post-intensive care syndrome-family'.)
Benefit and safety of antipsychotics for delirium (January 2017)
The benefit of antipsychotics for management of delirium in terminally ill patients has been called into question by a double-blind, randomized trial in which 247 inpatients of a hospice or palliative care service with mild to moderately severe delirium were randomly assigned to oral risperidone, haloperidol, or placebo every 12 hours for 72 hours . All patients received individualized supportive care. Patients who received antipsychotics had worse delirium-associated distress scores, greater delirium severity, more use of midazolam, more extrapyramidal effects, and worse short-term survival. In our view, this study does not justify abandoning the use of antipsychotics for severely agitated delirious patients, but points to the importance of reversing precipitating causes, providing best supportive care for symptomatic distress associated with delirium, and the need for additional research on the use of antipsychotics. (See "Overview of managing common non-pain symptoms in palliative care", section on 'Treatment'.)
Dosing interval for zoledronic acid in patients with bone metastases (January 2017)
For patients with bone metastases from a solid tumor, the approved dose and schedule of administration for zoledronic acid to reduce the frequency of skeletal-related events (SREs) is 4 mg every three to four weeks. Less frequent dosing is supported by data from CALGB (Alliance) trial 70604, which randomly assigned 1822 patients with bone metastases from breast or prostate cancer or multiple myeloma to the same dose of zoledronic acid every 4 or every 12 weeks for two years, starting with the first dose. There was no difference in the proportion of patients who developed at least one SRE (29.5 versus 28.6 percent) . There are now sufficient data in breast and prostate cancer to support dosing of zoledronic acid every 12 rather than every 4 weeks, and we suggest this approach for most patients. We still prefer every-four-week dosing, at least initially, for patients who have extensive or highly symptomatic bone metastases. (See "Osteoclast inhibitors for patients with bone metastases from breast, prostate, and other solid tumors", section on 'Dosing interval'.)
Updated MASCC/ESMO guidelines for nausea and emesis related to cancer treatment (October 2016)
Updated guidelines for prevention and management of cancer therapy-associated nausea and vomiting are available from the Multinational Association of Supportive Care in Cancer and the European Society of Medical Oncology (table 1), the consensus panel also provides guidance on the use of prophylactic antiemetics in patients undergoing radiation therapy. (See "Prevention and treatment of chemotherapy-induced nausea and vomiting in adults", section on 'Recommendations for specific groups'.)
Olanzapine for prevention of nausea and vomiting induced by highly emetogenic chemotherapy regimens (August 2016)
The antipsychotic olanzapine may be a particularly useful agent for preventing delayed chemotherapy-induced nausea and vomiting, which is often poorly controlled with conventional antiemetics. The effectiveness of adding olanzapine to a standard antiemetic regimen was shown in a trial in which 380 patients receiving highly emetogenic chemotherapy (cisplatin or doxorubicin/cyclophosphamide for breast cancer) were randomly assigned to dexamethasone, an NK1R antagonist, and a 5-HT3 receptor antagonist plus either olanzapine (10 mg daily orally on days 1 through 4) or placebo . The proportion of patients with no chemotherapy-induced nausea (the primary endpoint) was higher with olanzapine both in the first 24 hours after chemotherapy and in the delayed period. Rates of complete response (no emesis and no use of rescue medication) were also higher with olanzapine over a five-day period. Patients receiving olanzapine had more sedation on day 2 (severe in 5 percent), which resolved despite continued olanzapine. On the basis of this trial, we now suggest the addition of olanzapine on days 1 through 4 to standard antiemetic therapy for patients receiving highly emetogenic chemotherapy. (See "Prevention and treatment of chemotherapy-induced nausea and vomiting in adults", section on 'Olanzapine'.)
ASCO policy statement on access to opioids for cancer-related pain (July 2016)
Safe prescribing of opioids requires consideration of the risks associated with drug abuse, misuse, and diversion to the illicit marketplace. With increasing prescription drug abuse and opioid-associated overdose deaths, federal and state governments have taken additional steps to regulate opioids beyond the restrictions imposed by the federal Controlled Substances Act. However, inadequate treatment of cancer-related pain is a real problem, and concerns have been raised that many of these well-intentioned proposals will limit legitimate access to opioids for patients with cancer, and challenge the ability of oncologists and palliative care physicians to provide compassionate care that includes adequate pain relief. In response to these concerns, the American Society of Clinical Oncology (ASCO) has issued a policy statement that emphasizes principles for balancing opioid access with the need to curb misuse and abuse . (See "Cancer pain management: General principles and risk management for patients receiving opioids", section on 'Risk assessment and management for patients receiving opioids'.)
SELECTED END-STAGE CONDITIONS
Potential interaction between high-dose methotrexate and levetiracetam (November 2016)
Levetiracetam is sometimes used for prophylaxis and treatment of seizures in patients undergoing high-dose methotrexate (MTX) treatment for brain or other central nervous system (CNS) cancers, including lymphomas. Health Canada has issued a safety review describing a potential interaction between the two drugs, noting 13 reports received by the levetiracetam manufacturer and concluding that concurrent use can lead to significantly elevated levels of MTX and increased risk of toxicity . The labeling is being revised to recommend careful MTX blood level monitoring. Additional details are available from Lexi-Interact, the drug interactions tool included within UpToDate. (See "Therapeutic use and toxicity of high-dose methotrexate", section on 'Coadministered drugs that may interfere with excretion'.)
Proton pump inhibitors may diminish capecitabine efficacy (October 2016)
Two recent studies suggest that proton pump inhibitors diminish the effectiveness of capecitabine in the treatment of colorectal and gastroesophageal cancer [9,10]. It is hypothesized that higher gastric pH levels may inhibit dissolution and absorption of capecitabine. Patients who are receiving a capecitabine-containing regimen for adjuvant treatment of colon cancer or other malignancies should, when possible, avoid taking concurrent proton pump inhibitors. (See "Adjuvant therapy for resected stage III (node-positive) colon cancer", section on 'Capecitabine'.)
Declining use of feeding tubes in advanced dementia (August 2016)
Patients with advanced dementia commonly have eating problems in the final stages of illness, and caregivers are faced with decisions about whether to continue oral feeding by hand or place a long-term feeding tube. The available evidence fails to demonstrate any health benefits of tube feeding over ongoing hand feeding, and an increasing number of consensus-based guidelines advocate against feeding tube placement in this setting. In keeping with these recommendations, a recent study in the United States found that the proportion of nursing home residents with advanced dementia who received a feeding tube within one year of the onset of feeding problems decreased by approximately 50 percent between the years 2000 and 2014 . Advance care planning is critical in the management of patients with dementia and should include preparatory discussions about eating problems and other common complications encountered in the advanced stages of the disease. (See "Palliative care of patients with advanced dementia", section on 'Oral versus tube feeding'.)
Use of adjunctive antidepressants for treating complicated grief with comorbid depression (August 2016)
Complicated grief is a distinct syndrome that often occurs in bereaved individuals and is characterized by maladaptive thoughts, dysfunctional behaviors, and poorly regulated emotions. The best treatment for complicated grief is psychotherapy that is specific for complicated grief (complicated grief therapy, CGT). Antidepressants are frequently prescribed as an adjunctive therapy. Although adjunctive antidepressants do not appear to mitigate symptoms of complicated grief, they can improve comorbid unipolar major depression, which is common. In a recent trial, 395 adults with complicated grief were randomly assigned to citalopram alone, placebo alone, CGT plus citalopram, or CGT plus placebo . As expected, more patients responded to CGT plus placebo than placebo alone. The addition of citalopram did not significantly improve complicated grief outcomes. However, improvement of depressive symptoms was greater with citalopram. Thus, in patients with complicated grief and depressive symptoms, the addition of citalopram may be helpful. (See "Complicated grief in adults: Treatment", section on 'Other options'.)
