Screening for the Desire to Die in the First Palliative Care Encounter: A Proof-of-Concept Study.

Context: There is a lack of consensus about the appropriate moment to assess a potential wish to hasten death (WTHD) in patients with life-threatening illness, despite evidence of its positive appraisal among patients. Objectives: To evaluate the practical potential and acceptability of questions about the WTHD in the first palliative care (PC) clinical encounter. Design: A proof-of-concept single-arm unmasked trial. Subjects: We enrolled 30 advanced cancer patients, 16 inpatients and 14 outpatients in their first PC clinical encounter. Measurements: We assessed the WTHD using a semistructured interview guide, the Assessment of the Frequency and Extent of the Desire to Die (AFEDD) embedded in a multidimensional needs assessment carried out during the first PC encounter. Information about practical potential [patients consider the assessment (a) important and (b) helpful] and acceptability [patients (a) understand and (b) are not bothered by the questions] was obtained. Results: Thirty-two patients were approached and 30 (94%) agreed to participate. The WTHD was present in two outpatients and eight inpatients. The question to assess WTHD were well understood by 94% of patients and was considered not bothersome by 87% and quite or very helpful by 80%, regardless of whether they had WTHD. Conclusions: The results support that clinicians can integrate screening for the WTHD in usual clinical practice within a multidimensional needs assessment. Patient acceptability suggests that this as a part of patient-centered care including in the first PC clinical encounter. Further studies are needed to confirm efficacy and safety in larger and different populations.

Efficacy of Cryoablation to Control Cancer Pain: A Systematic Review.

The use of opioids to control cancer pain could be insufficient. Interventional techniques such as a cryoablation have emerged as alternatives to opioids. OBJECTIVES: To summarize the current scientific evidence on the use of cryoablation to control cancer pain. METHODS: A systematic search of the Scopus, PubMed, and Cochrane databases was performed. All articles published before December 31, 2015, whose title or abstract specified cancer pain control as the endpoint were selected. Articles without abstracts and all nonsystematic reviews were excluded. RESULTS: 22 articles were included: 1 randomized clinical trial (RCT), 2 non-RCTs, 1 ambispective study, 9 retrospective studies, 2 nonspecified cohort studies, 3 case series, and 4 case reports. 496 patients with 580 lesions were treated. Lung cancer was the most common primary tumor. 82.8% of the metastases were bone metastases, with or without soft tissue involvement. Cryoablation decreased mean pain scores by 62.5% at 24 hours post-cryoablation, by 70% at 3 months, and by 80.9% at 6 months. Cryoablation was associated with a 44.2% improvement in quality of life after 4 weeks and a 59.6% improvement at 8 weeks. The need for opioids decreased by 75% at 24 hours and by 61.7% at 3 months. Cryoablation in combination with radiotherapy, vertebroplasty, or bisphosphonates appears to be better than cryoablation alone. Complications were highly variable among the studies, but no fatal complications were reported. CONCLUSIONS: Cryoablation is effective in controlling cancer pain without relevant side effects. However, more studies are needed to confirm these results.
