Purpose of review: This review aims to synthesise the evidence from systematic reviews and meta-analyses on the efficacy of dignity therapy (DT) in relation to psychosocial and spiritual outcomes in the context of person-centred and culturally competent care for people with supportive and palliative care needs.

Recent findings: Thirteen reviews were found, including seven conducted by nurses. Most reviews were of high quality, including various study populations such as cancer, motor neurone disease and non-malignant conditions. Six psychosocial and spiritual outcomes were identified: quality of life, anxiety, depression, hopefulness, meaning and purpose in life, and suffering based on the cultural variations in the implementation of DT.

Summary: DT has a positive impact on anxiety, depression, suffering, and meaning and purpose in life for people with palliative care needs, but the evidence is somewhat conflicted as to whether DT is effective in improving hope, quality of life and spiritual outcomes in the context of culturally competent care. Nurse-led DT seems desirable given its pivotal role when caring for people with palliative care needs. More randomised controlled trials should be conducted for people with different cultural backgrounds to provide person-centred, culturally competent supportive and palliative care.

Purpose of review: The misuse of opioids has increased significantly in recent decades. Historically, cancer patients have not been considered at risk of opioid misuse. However, cancer pain is common, and opioids are often prescribed. Guidelines addressing opioid misuse often exclude cancer patients. Given that misuse is associated with significant harm and a reduction in quality of life, it is important to understand the risk of opioid misuse in cancer patients and how we can recognise and treat it.

Recent findings: Early cancer diagnoses and treatments have improved cancer survival rates, leading to a larger population of cancer patients and survivors. Opioid use disorder (OUD) may precede a cancer diagnosis or may develop during or after treatment. The effect of OUD extends from an individual patient to a societal level. This review examines the increasing incidence of OUD in cancer patients, ways to identify patients with OUD such as behaviour change and screening scales, prevention of OUD such as limited and targeted opioid prescriptions, and evidence-based treatment suggestions for OUD.

Summary: OUD in cancer patients has only relatively recently been recognised as a growing problem. Early identification, involvement of the multidisciplinary team, and treatment can reduce the negative impact of OUD.

Purpose of review: Tapentadol is the first of a new class of analgesics, having synergistic µ-opioid receptor agonist and noradrenaline reuptake inhibitory actions. It has been widely researched in many areas of pain, often in noninferiority studies against potent opioids. This review describes all randomized and recent nonrandomized studies of tapentadol in adults with cancer pain.

Recent findings: Tapentadol has been shown to be at least as effective as morphine and oxycodone in five randomized (two of which were multicenter and double-blind) and a range of nonrandomized trials, although caution is needed when interpreting these results. It is effective in both opioid-naive patients and those already taking opioids. By having a lower µ-opioid receptor binding affinity, it has fewer opioid-related toxicities such as constipation and nausea. A recent randomized trial comparing tapentadol to tapentadol plus duloxetine in patients with chemotherapy-induced peripheral neuropathy shows similar improvement in both groups in a range of pain relieving and quality of life measures, with similar adverse effects.

Summary: Tapentadol has been shown in a range of studies to be an effective analgesic and thus should be considered as an alternative to morphine and oxycodone, especially when opioid toxicities are an issue.

Purpose of review: Within the context of palliative care, existential suffering (ES) can be an exclusive source of suffering or intertwined with physical pain and/or psychological and spiritual suffering. With newly emerging modalities for addressing this phenomenon and its increasing salience given that many patients cite ES as a significant contributing factor to requests for hastened death, a review of recent interventions for addressing ES at the end of life is timely.

Recent findings: This review of newer approaches to dealing with ES in the palliative context suggests some promising new modalities and pharmacological interventions, such as brain stimulation and the use of psychedelics. The use of other pharmacological interventions, such as palliative sedation and lethal injections, solely for the alleviation of existential distress remains ethically controversial and difficult to disentangle from other forms of suffering, not least because a clear clinical definition of ES has yet to emerge in the literature.

Summary: The evaluation of end-of-life (EOL) ES mitigating tools should also consider how broader contexts, such as institutional arrangements and barriers, and cultural factors may influence the optimal management of dying persons' ES in the palliative care setting.

Purpose of the review: Patient-reported outcomes are one of the most valuable clinical outcome measures. In palliative care, however, they are often difficult to retrieve. Therefore, proxy-reported outcomes are sometimes used as a surrogate. As there have been concerns about the validity of these by-proxy reports, the authors reviewed the most recent literature for the most recent insights in using proxy-reported outcomes.

Recent findings: The authors found very little new research on patient versus proxy-reported outcomes in palliative care. The results of the studies the authors found seem to correlate with older evidence concluding that there are many factors influencing a discrepancy between patients' outcomes and how this is perceived by their proxies, such as the well-being paradox, caregiver burden, and the proxies' own mental well-being.

Summary: While proxies' opinions and knowledge of the patients' values are important factors to consider, proxy-reported outcomes should be used with caution and viewed as a complementary perspective rather than a true substitute for the individual patient's outcome.

Purpose of review: Artificial intelligence (AI) is a transformative technology that has the potential to improve and augment the clinical workflow in supportive and palliative care (SPC). The objective of this study was to provide an overview of the recent studies applying AI to SPC in cancer patients.

Recent findings: Between 2020 and 2022, 29 relevant studies were identified and categorized into two applications: predictive modeling and text screening. Predictive modeling uses machine learning and/or deep learning algorithms to make predictions regarding clinical outcomes. Most studies focused on predicting short-term mortality risk or survival within 6 months, while others used models to predict complications in patients receiving treatment and forecast the need for SPC services. Text screening typically uses natural language processing (NLP) to identify specific keywords, phrases, or documents from patient notes. Various applications of NLP were found, including the classification of symptom severity, identifying patients without documentation related to advance care planning, and monitoring online support group chat data.

Summary: This literature review indicates that AI tools can be used to support SPC clinicians in decision-making and reduce manual workload, leading to potentially improved care and outcomes for cancer patients. Emerging data from prospective studies supports the clinical benefit of these tools; however, more rigorous clinical validation is required before AI is routinely adopted in the SPC clinical workflow.

Purpose of review: Half of all cancer patients will develop cancer-related pain, and a fifth of these patients will continue to experience pain refractory to maximal pharmacological therapy. This, together with the opioid crisis, has prompted a resurgence in neurosurgical treatments. Neuromodulatory or neuroablative procedures are largely used for various nonmalignant, chronic pain conditions, but there is growing evidence to support their use in cancer pain. This review aims to cover the main neurosurgical treatments that may prove useful in the changing sphere of cancer pain treatment.

Recent findings: Neuromodulation techniques for pain have largely replaced neuroablation in neurosurgical practice due to the higher risk of inadvertent permanent neurological deficits from the latter. When compared to neuroablative approaches for severe treatment-refractory cancer pain, neuromodulation is more expensive (largely due to implant cost) and requires more follow-up, with greater engagement needed from the health service, the patient and their carers. Furthermore, neuroablation has a more rapid onset of effect.

Summary: Neuromodulation techniques for pain have largely replaced neuroablation in neurosurgical practice due to the higher risk of inadvertent permanent neurological deficits from the latter. Whilst this approach is beneficial when treating nonmalignant pain, neuromodulation in patients with pain related to advanced cancer still has a limited role. Neuroablative procedures are less expensive, require less follow-up, and can have a lower burden on health services, patients and their carers.

Purpose of review: The exploration for accurate ways to predict survival for advanced cancer patients continues to be a significant theme despite the advent of objective criteria and their combination with clinical criteria. The purpose of this article was to review some of the latest studies relating to prognostication and the capacity to predict survival during the terminal cancer stage.

Recent findings: Recent studies show notable prognostication approaches using genetic tests and advanced computation methods such as machine learning, which we will summarize.

Summary: Significant effort has been made to improve the accuracy of survival estimation for advanced cancer patients. The main goals are to optimize individualized patient management and uses of resources. Advanced techniques, including genetic markers and machine learning techniques, may improve the accuracy of prediction.

Current Opinion in Supportive and Palliative Care was launched in 2007. It is one of a successful series of review journals whose unique format is designed to provide a systematic and critical assessment of the literature as presented in the many primary journals. The fields of supportive and palliative care are divided into 12 sections that are reviewed once a year. Each section is assigned a Section Editor, a leading authority in the area, who identifies the most important topics at that time. Here we are pleased to introduce the Journal's Section Editors for this issue.
