Prospective, observational study of pain and analgesic prescribing in medical oncology outpatients with breast, colorectal, lung, or prostate cancer

GPR37 Activation Alleviates Bone Cancer Pain via the Inhibition of Osteoclastogenesis and Neuronal Hyperexcitability

Osteolytic bone cancer pain is a primary concern for cancer patients with bone metastasis, and current therapies offer inadequate pain relief. The present study demonstrates that activation of the G protein-coupled receptor 37 (GPR37) by neuroprotectin D1 (NPD1) or artesunate (ARU) alleviates both acute and persistent pain in multiple mouse models of bone cancer. GPR37 agonists also protect against cancer-induced bone destruction. Mechanistically, NPD1 or ARU binding to GPR37 in macrophages promotes the release of IL-10, which further inhibits cancer-induced osteoclastogenesis. Moreover, direct activation of GPR37 in dorsal root ganglion (DRG) neurons and the spinal dorsal horn reduces action potential firing and the frequency of spontaneous excitatory postsynaptic currents (sEPSCs), thereby suppressing cancer-induced neuronal hyperexcitability. Importantly, the analgesic and protective effects of NPD1 and ARU are abolished in Gpr37-/- mice, and β-arrestin 2 is identified as a key mediator in IL-10 release and neuronal inhibition. In patients with bone metastases, plasma levels of endogenous NPD1 are negatively correlated with both pain intensity and the bone resorption marker CTX-I. Collectively, these findings highlight GPR37 activation as a potential therapeutic strategy for alleviating bone cancer pain through direct and synergistic inhibition of osteoclastogenesis and neuronal hyperexcitability.

Adding Metastasis-Directed Therapy to Standard-of-Care Systemic Therapy for Oligometastatic Breast Cancer (EXTEND): A Multicenter, Randomized Phase 2 Trial

PURPOSE

Prior evidence suggests a progression-free survival (PFS) benefit from adding metastasis-directed therapy (MDT) to standard-of-care (SOC) systemic therapy for patients with some oligometastatic solid tumors. Randomized trials testing this hypothesis in breast cancer have yet to be published. We sought to determine whether adding MDT to SOC systemic therapy improves PFS in oligometastatic breast cancer.

METHODS AND MATERIALS

External Beam Radiation to Eliminate Nominal Metastatic Disease is a multicenter phase 2 randomized basket trial testing the addition of MDT to SOC systemic therapy in patients with ≤5 metastases (NCT03599765). Patients were randomly assigned 1:1 to MDT (definitive local treatment to all sites of disease, plus SOC systemic therapy) or to SOC systemic therapy-only. Primary endpoint was PFS, and secondary endpoints included overall survival, time to subsequent line of systemic therapy, and time to the appearance of new metastases. Exploratory analyses included quality of life and systemic immune response measures.

RESULTS

From September 2018 through July 2022, 22 and 21 patients were randomly assigned to the MDT and no-MDT arms, respectively. At a median follow-up of 24.8 months, PFS was not improved with the addition of MDT to SOC systemic therapy (median PFS 15.6 months MDT vs 24.9 months no-MDT [hazard ratio, 0.91; 95% CI, 0.34-2.48; P = .86]). Similarly, MDT did not improve overall survival, time to subsequent line of systemic therapy, or time to the appearance of new metastases (all P > .05). No significant differences were found in quality of life measures, systemic T-cell activation, or T-cell stimulatory cytokine concentration.

CONCLUSIONS

Among patients with oligometastatic breast cancer, the addition of MDT to SOC systemic therapy did not improve PFS. These findings suggest that MDT may have no systemic benefit in otherwise unselected patients with oligometastatic breast cancer, although this trial was limited by a heterogeneous and small sample size and overperformance of both treatment arms.

Opioid conversion in adults with cancer: MASCC-ASCO-AAHPM-HPNA-NICSO guideline

PURPOSE

To standardize and improve the safety and efficacy of opioid conversion in people with cancer.

METHODS

The Multinational Association of Supportive Care in Cancer (MASCC), American Society of Clinical Oncology (ASCO), American Academy of Hospice and Palliative Medicine (AAHPM), Hospice and Palliative Nurses Association (HPNA), and Network Italiano Cure di Supporto in Oncologia (NICSO) convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal consensus process. The systematic review focused on randomized and non-randomized studies published from database inception to June 2022. A modified Delphi approach was used to develop and finalize recommendations. Recommendations developed by the Expert Panel underwent two rounds of consensus voting before being finalized.

RESULTS

The systematic review, published separately, identified 208 eligible studies. These studies provided mixed and inclusive findings regarding optimal approaches to opioid conversion. In consensus voting, 58 of 84 statements met or exceeded the required 75% level of agreement and were accepted. This process demonstrated some consistencies in conversion ratios between particular opioids internationally, but also uncovered variability in opioid conversion ratios among experts, particularly for methadone.

RECOMMENDATIONS

The recommendations address three main topics: pre-conversion assessments, strategies for conversion, and post-conversion assessments. The goal is to reduce the relative risk of overdosing or under-dosing opioids when converting from one opioid to another or converting administration routes. The strength of the evidence from the trials is modest, and there are large clinical practice and research gaps. The panel hopes this guideline will establish an international best practice baseline that can be built upon by new research and better-designed trials.

Psychological assessment and the role of the psychologist in early palliative care

Background

Early palliative care (EPC) is a recommended model for improving the quality of life for patients with advanced cancer and their caregivers. However, limited research has focused on the role of psychological evaluation within EPC. The Veneto Institute of Oncology (IOV), a Comprehensive Cancer Centre, employs an interdisciplinary team to assess patients with advanced-stage disease. This study aims to assess the psychological needs of these patients, investigate any correlations between psychological symptoms (PSs) and factors such as awareness of diagnosis and prognosis, symptoms detected using the Edmonton Symptom Assessment System (ESAS), as well as the patient's gender, age, social issues, and survival and to clarify the psychologist's role within the interdisciplinary team.

Methods

Data were retrieved from a prospectively maintained database. From 1st January 2018 to 31st December 2021, 819 consecutive patients were evaluated during EPC consultations, with 753 participants enrolled in the study. The ESAS was administered to each patient before the consultation.

Results

More than half of the patients (385, 57.1%) reported at least one PS, with an ESAS score of ≥4. Specifically, 34.9% reported depression, 28.7% reported anxiety, and 43.2% indicated feeling "not well." Referring oncologists tended to overestimate the presence of PSs compared to patient self-reports (51.8% versus 41.3%). According to the psychologists' assessment, 29.2% of participants were found to have depression, and 10.8% of participants had anxiety. Additionally, 31 patients (10.8%) with psychological disorders were diagnosed with an adaptation disorder related to a physical condition. The psychology service engaged 47% of patients, while 18.5% declined psychological support. Patients exhibiting other ESAS symptoms with scores of ≥4 had an increased odds ratio for reporting PSs of ≥4. However, multivariable analysis revealed no significant relationship between PSs and awareness of diagnosis and prognosis.

Conclusion

The systematic use of self-assessment in EPC is essential for understanding patient's experience, determining whether PSs stem from physical disorders, and prioritizing interventions. Awareness of prognosis does not correlate with increased anxiety and depression in patients. Therefore, EPC is an ideal opportunity to discuss prognosis and facilitate patients' end-of-life choices early in their care journey.

Racial Disparities in Opioid Prescribing in the United States from 2011 to 2021: A Systematic Review and Meta-Analysis

Background

This meta-analysis is an update to a seminal meta-analysis on racial/ethnic disparities in pain treatment in the United States (US) published in 2012. Since then, literature has accumulated on the topic and important policy changes were made.

Objective

Examining racial/ethnic disparities in pain management and investigating key moderators of the association between race/ethnicity and pain outcomes in the US.

Methods

We performed a systematic search of publications (between January 2011 and February 2021) from the Scopus database. Search terms included: race, racial, racialized, ethnic, ethnicity, minority, minorities, minoritized, pain treatment, pain management, and analgesia. All studies were observational, examining differences in receipt of pain prescription medication in various settings, across racial or ethnic categories in US adult patient populations. Two binary analgesic outcomes were extracted: 1) prescription of "any" analgesia, and 2) prescription of "opioid" analgesia. We analyzed these outcomes in two populations: 1) Black patients, with White patients as a reference; and 2) Hispanic patients, with non-Hispanic White patients as a reference.

Results

The meta-analysis included twelve studies, and the systematic review included forty-three studies. Meta-analysis showed that, compared to White patients, Black patients were less likely to receive opioid analgesia (OR 0.83, 95% CI [0.73-0.94]). Compared to non-Hispanic White patients, Hispanic patients were less likely to receive opioid analgesia (OR 0.80, 95% CI [0.72-0.88]).

Conclusion

Despite a decade's gap, the findings indicate persistent disparities in prescription of, and access to opioid analgesics for pain among Black and Hispanic populations in the US.

Perceptions of prescription opioids among marginalized patients with hematologic malignancies in the context of the opioid epidemic: a qualitative study

PURPOSE

Opioids are essential for treating pain in hematologic malignancies (HM), yet are heavily stigmatized in the era of the opioid epidemic. Stigma and negative attitudes towards opioids may contribute to poorly managed cancer pain. We aimed to understand patient attitudes towards opioids for HM pain management, particularly among historically marginalized populations.

METHODS

We interviewed a convenience sample of 20 adult patients with HM during outpatient visits at an urban academic medical center. Semi-structured interviews were audio-recorded, transcribed, and qualitatively analyzed using the framework method.

RESULTS

Among 20 participants, 12 were female and half were Black. Median age was 62 (interquartile range = 54-68). HM diagnoses included multiple myeloma (n = 10), leukemia (n = 5), lymphoma (n = 4), and myelofibrosis (n = 1). Eight themes emerged from interviews that seemed to influence HM-related pain self-management, including (1) fear of opioid-related harms, (2) opioid side effects and harms to health, (3) fatalism and stoicism, (4) perceived value of opioids for HM-related pain, (5) low perceived susceptibility to opioid-related harms and externalizing blame, (6) preferences for non-opioid pain management approaches, (7) trust in providers and opioid accessibility, and (8) external sources of pain management support and information.

CONCLUSIONS

This qualitative study demonstrates that fears and stigmatized views of opioids can conflict with marginalized patients' needs to manage debilitating HM-related pain. Negative attitudes towards opioids were shaped by the opioid epidemic and reduced willingness to seek out or use analgesics.

IMPLICATIONS FOR CANCER SURVIVORS

These findings help expose patient-level barriers to optimal HM pain management, revealing attitudes, and knowledge to be targeted by future pain management interventions in HM.

Racial differences in treatment adherence and response to acupuncture and cognitive behavioral therapy for insomnia among Black and White cancer survivors

BACKGROUND

Racial disparities in sleep are well-documented. However, evidence-based options for addressing these disparities are lacking in cancer populations. To inform future research on sleep interventions, this study aims to understand racial differences in treatment responses to acupuncture and cognitive behavioral therapy for insomnia (CBT-I) among Black and White cancer survivors.

METHODS

We conducted a secondary analysis of a comparative effectiveness trial evaluating acupuncture versus CBT-I for insomnia in cancer survivors. We compared insomnia severity, sleep characteristics, and co-morbid symptoms, as well as treatment attitudes, adherence, and responses among Black and White participants.

RESULTS

Among 156 cancer survivors (28% Black), Black survivors reported poorer sleep quality, longer sleep onset latency, and higher pain at baseline, compared to White survivors (all p < 0.05). Black survivors demonstrated lower adherence to CBT-I than White survivors (61.5% vs. 88.5%, p = 0.006), but their treatment response to CBT-I was similar to white survivors. Black survivors had similar adherence to acupuncture as white survivors (82.3% vs. 93.4%, p = 0.16), but they had greater reduction in insomnia severity with acupuncture (-3.0 points, 95% CI -5.4 to 0.4, p = 0.02).

CONCLUSION

This study identified racial differences in sleep characteristics, as well as treatment adherence and responses to CBT-I and acupuncture. To address racial disparities in sleep health, future research should focus on improving CBT-I adherence and confirming the effectiveness of acupuncture in Black cancer survivors.

Early Hospice Consultation Team Engagement for Cancer Pain Relief: A Case Report

This case report explores the challenges and complexities associated with opioid management of cancer pain, emphasizing the importance of early involvement of a hospice consultation team and the adoption of a multidisciplinary approach to care. A 56-year-old man with advanced pancreatic cancer experienced escalating pain and inappropriate opioid prescriptions, highlighting the shortcomings of traditional pain management approaches. Despite procedural intervention by the attending physician and increased opioid dosages, the patient's condition deteriorated. Subsequently, the involvement of a hospice consultation team, in conjunction with collaborative psychiatric care, led to an overall improvement. The case underscores the necessity of early hospice engagement, psychosocial assessments, and collaborative approaches in the optimization of patient-centered palliative care.

Social Determinants of Health and Cancer Pain in the US: Scoping Review

Social determinants of health (SDOH) are structural factors that yield health inequities. Within the context of cancer, these inequities include screening rates and survival rates, as well as higher symptom burden during and after treatment. While pain is one of the most frequently reported symptoms, the relationship between SDOHs and cancer pain is not well understood. The purpose of this study is to describe and synthesize the published research that has evaluated the relationships between SDOH and cancer pain. A systematic search of PubMed, CINAHL, and Embase was conducted to identify studies in which cancer pain and SDOH were described. In all, 20 studies met the inclusion criteria. In total, 14 studies reported a primary aim related to SDOH and cancer pain. Demographic variables including education or income were used most frequently. Six specific measurements were utilized to measure SDOH, such as the acculturation scale, the composite measure of zip codes for poverty level and blight prevalence, or the segregation index. Among the five domains of SDOH based on Healthy People 2030, social and community was the most studied, followed by economic stability, and education access and quality. The neighborhood and built environment domain was the least studied. Despite increasing attention to SDOH, the majority of published studies use single-dimension variables derived from demographic data to evaluate the relationships between SDOH and cancer pain. Future research is needed to explore the intersectionality of SDOH domains and their impact on cancer pain. Additionally, intervention studies should be conducted to address existing disparities and to reduce the incidence and impact of cancer pain.

Monitoring Adolescent and Young Adult Patients With Cancer via a Smart T-Shirt: Prospective, Single-Cohort, Mixed Methods Feasibility Study (OncoSmartShirt Study)

Background

Wearables that measure vital parameters can be potential tools for monitoring patients at home during cancer treatment. One type of wearable is a smart T-shirt with embedded sensors. Initially, smart T-shirts were designed to aid athletes in their performance analyses. Recently however, researchers have been investigating the use of smart T-shirts as supportive tools in health care. In general, the knowledge on the use of wearables for symptom monitoring during cancer treatment is limited, and consensus and awareness about compliance or adherence are lacking.

objectives

The aim of this study was to evaluate adherence to and experiences with using a smart T-shirt for the home monitoring of biometric sensor data among adolescent and young adult patients undergoing cancer treatment during a 2-week period.

Methods

This study was a prospective, single-cohort, mixed methods feasibility study. The inclusion criteria were patients aged 18 to 39 years and those who were receiving treatment at Copenhagen University Hospital - Rigshospitalet, Denmark. Consenting patients were asked to wear the Chronolife smart T-shirt for a period of 2 weeks. The smart T-shirt had multiple sensors and electrodes, which engendered the following six measurements: electrocardiogram (ECG) measurements, thoracic respiration, abdominal respiration, thoracic impedance, physical activity (steps), and skin temperature. The primary end point was adherence, which was defined as a wear time of >8 hours per day. The patient experience was investigated via individual, semistructured telephone interviews and a paper questionnaire.

Results

A total of 10 patients were included. The number of days with wear times of >8 hours during the study period (14 d) varied from 0 to 6 (mean 2 d). Further, 3 patients had a mean wear time of >8 hours during each of their days with data registration. The number of days with any data registration ranged from 0 to 10 (mean 6.4 d). The thematic analysis of interviews pointed to the following three main themes: (1) the smart T-shirt is cool but does not fit patients with cancer, (2) the technology limits the use of the smart T-shirt, and (3) the monitoring of data increases the feeling of safety. Results from the questionnaire showed that the patients generally had confidence in the device.

Conclusions

Although the primary end point was not reached, the patients' experiences with using the smart T-shirt resulted in the knowledge that patients acknowledged the need for new technologies that improve supportive cancer care. The patients were positive when asked to wear the smart T-shirt. However, technical and practical challenges in using the device resulted in low adherence. Although wearables might have potential for home monitoring, the present technology is immature for clinical use.

Short-term pain control after palliative radiotherapy for uncomplicated bone metastases: a prospective cohort study

This study aimed at evaluating the efficacy of different radiotherapy (RT) fractionation regimens in managing uncomplicated painful bone metastases (BM) and identifying predictive factors for pain control. Patients with 1 to 4 symptomatic BM from any primary solid tumors and a life expectancy exceeding 3 months were included in the study and received palliative RT, with SBRT restricted in the context of oligometastatic disease or in patients with good prognosis. Pain analysis using the Brief Pain Inventory (BPI) tool was conducted at baseline, 1 and 3 months after RT. Analgesic intake was recorded as morphine-equivalent doses (OME). Pain response was assessed using the International Consensus on Palliative Radiotherapy Endpoint (ICPRE). Multivariate logistic regression analyzed patient-related, tumor-related, and treatment-related factors predicting BM pain control at 3 months post-RT. From Feb 2022 to Feb 2023, 44 patients with 65 symptomatic BM were investigated. Breast (32%) and lung (24%) tumors were the most common primary tumors. Treatment plans included 3DCRT (60%) and VMAT (40%), with a median biological effective dose for tumors (BED) of 29 Gy [14-108]. All patients completed the 3-month follow-up. Pain response rates were 62% at 1 month and 60% at 3 months. Responders had better PS ECOG scores (67%; P = 0.008) and received active systemic therapies (67%: P = 0.036). Non-responders had lower pretreatment BPI (mean: 13.7 vs. 58.2; P = 0.032), with significantly higher values after 1 month (mean: 9.1 vs. 5.3, P = 0.033). Baseline BPI (OR: 1.17; 95% CI: 1.032-1.327; P = 0.014) and BPI at 1 month (OR: 0.83; 95% CI: 0.698-0.976; P = 0.025) were independent predictors of pain response at 3 months. Our findings show that palliative RT ensured short-term pain control in patients with BM, regardless of tumor type and dose-fractionation regimen. A larger sample size and a longer follow-up could potentially identify which patients are likely to benefit most from RT, and which fractionation might be indicated for achieving a durable pain relief. A multidisciplinary approach is paramount to provide a better care to BM patients.

Association of Race/Ethnicity, Persistent Poverty, and Opioid Access Among Patients with Gastrointestinal Cancer Near the End of Life

BACKGROUND

Social determinants of health (SDoH) can impact access to healthcare. We sought to assess the association between persistent poverty (PP), race/ethnicity, and opioid access among patients with gastrointestinal cancer near the end-of-life (EOL).

METHODS

SEER-Medicare patients with gastric, liver, pancreatic, biliary, colon, and rectal cancer were identified between 2008 and 2016 near EOL, defined as 30 days before death or hospice enrolment. Data were linked with county-level poverty from the American Community Survey and the US Department of Agriculture (2000-2015). Counties were categorized as never high-poverty (NHP), intermittent high-poverty (IHP) and persistent poverty (PP). Trends in opioid prescription fills and daily dosages (morphine milligram equivalents per day) were examined.

RESULTS

Among 48,631 Medicare beneficiaries (liver: n = 6551, 13.5%; pancreas: n = 13,559, 27.9%; gastric: n = 5486, 1.3%; colorectal: n = 23,035, 47.4%), there was a steady decrease in opioid prescriptions near EOL. Black, Asian, Hispanic, and other racial groups had markedly decreased odds of filling an opioid prescription near EOL (Black: OR 0.84, 95% CI 0.79-0.90; Asian: OR 0.86, 95% CI 0.79-0.94; Hispanic: OR 0.90, 95% CI 0.84-0.95; Other: OR 0.83, 95% CI 0.74-0.93; all p < 0.05). Even after filling an opioid prescription, this subset of patients received lower daily doses versus White patients (Black: -16.5 percentage points, 95% CI -21.2 to -11.6; Asian: -11.9 percentage points, 95% CI -18.5 to -4.9; Hispanic: -19.1 percentage points, 95%CI -23.5 to -14.6; all p < 0.05). The disparity in opioid access and average daily doses among was attenuated in IHP/PP areas for Asian, Hispanic, and other racial groups, yet exacerbated among Black patients.

CONCLUSIONS

Race/ethnicity-based disparities in EOL pain management persist with SDoH-based variations in EOL opioid use. In particular, PP impacted EOL opioid access and utilization.

SIO-ASCO guideline on integrative medicine for cancer pain management: implications for racial and ethnic pain disparities

Racial and ethnic disparities in pain management pose major challenges to equitable cancer care delivery. These disparities are driven by complex interactions between patient-, provider-, and system-related factors that resist reductionistic solutions and require innovative, holistic approaches. On September 19, 2022, the Society for Integrative Oncology and the American Society of Clinical Oncology published a joint guideline to provide evidence-based recommendations on integrative medicine for cancer pain management. Integrative medicine, which combines conventional treatments with complementary modalities from cultures and traditions around the world, are uniquely equipped to resonate with diverse cancer populations and fill existing gaps in pain management. Although some complementary modalities, such as music therapy and yoga, lack sufficient evidence to make a specific recommendation, other modalities, such as acupuncture, massage, and hypnosis, demonstrated an intermediate level of evidence, resulting in moderate strength recommendations for their use in cancer pain management. However, several factors may hinder real-world implementation of the Society for Integrative Oncology and the American Society of Clinical Oncology guideline and must be addressed to ensure equitable pain management for all communities. These barriers include, but are not limited to, the lack of insurance coverage for many complementary therapies, the limited diversity and availability of complementary therapy providers, the negative social norms surrounding complementary therapies, the underrepresentation of racial and ethnic subgroups in the clinical research of complementary therapies, and the paucity of culturally attuned interventions tailored to diverse individuals. This commentary examines both the challenges and the opportunities for addressing racial and ethnic disparities in cancer pain management through integrative medicine.

Ethical considerations in the relief of cancer pain

The management of pain for patients with cancer and cancer survivors is a critical clinical task that involves a multitude of ethical issues at almost every phase of the cancer experience. This review is divided into three sections: In the first, we address rights and duties in the relief of pain from the perspective of patients, clinicians, health care institutions and organizations, and public policy. This section includes a detailed description of issues and duties in relation to opioid misuse and addiction. In the second section, we discuss the ethical consideration of therapeutic planning. The final section addresses ethical considerations in the management of pain at the end of life including a detailed discussion regarding ethical issues relating to the use of palliative sedation as a clinical intervention of last resort.

Addition of Metastasis-Directed Therapy to Intermittent Hormone Therapy for Oligometastatic Prostate Cancer: The EXTEND Phase 2 Randomized Clinical Trial

Importance

Despite evidence demonstrating an overall survival benefit with up-front hormone therapy in addition to established synergy between hormone therapy and radiation, the addition of metastasis-directed therapy (MDT) to hormone therapy for oligometastatic prostate cancer, to date, has not been evaluated in a randomized clinical trial.

Objective

To determine in men with oligometastatic prostate cancer whether the addition of MDT to intermittent hormone therapy improves oncologic outcomes and preserves time with eugonadal testosterone compared with intermittent hormone therapy alone.

Design, Setting, Participants

The External Beam Radiation to Eliminate Nominal Metastatic Disease (EXTEND) trial is a phase 2, basket randomized clinical trial for multiple solid tumors testing the addition of MDT to standard-of-care systemic therapy. Men aged 18 years or older with oligometastatic prostate cancer who had 5 or fewer metastases and were treated with hormone therapy for 2 or more months were enrolled to the prostate intermittent hormone therapy basket at multicenter tertiary cancer centers from September 2018 to November 2020. The cutoff date for the primary analysis was January 7, 2022.

Interventions

Patients were randomized 1:1 to MDT, consisting of definitive radiation therapy to all sites of disease and intermittent hormone therapy (combined therapy arm; n = 43) or to hormone therapy only (n = 44). A planned break in hormone therapy occurred 6 months after enrollment, after which hormone therapy was withheld until progression.

Main Outcomes and Measures

The primary end point was disease progression, defined as death or radiographic, clinical, or biochemical progression. A key predefined secondary end point was eugonadal progression-free survival (PFS), defined as the time from achieving a eugonadal testosterone level (≥150 ng/dL; to convert to nanomoles per liter, multiply by 0.0347) until progression. Exploratory measures included quality of life and systemic immune evaluation using flow cytometry and T-cell receptor sequencing.

Results

The study included 87 men (median age, 67 years [IQR, 63-72 years]). Median follow-up was 22.0 months (range, 11.6-39.2 months). Progression-free survival was improved in the combined therapy arm (median not reached) compared with the hormone therapy only arm (median, 15.8 months; 95% CI, 13.6-21.2 months) (hazard ratio, 0.25; 95% CI, 0.12-0.55; P < .001). Eugonadal PFS was also improved with MDT (median not reached) compared with the hormone therapy only (6.1 months; 95% CI, 3.7 months to not estimable) (hazard ratio, 0.32; 95% CI, 0.11-0.91; P = .03). Flow cytometry and T-cell receptor sequencing demonstrated increased markers of T-cell activation, proliferation, and clonal expansion limited to the combined therapy arm.

Conclusions and Relevance

In this randomized clinical trial, PFS and eugonadal PFS were significantly improved with combination treatment compared with hormone treatment only in men with oligometastatic prostate cancer. Combination of MDT with intermittent hormone therapy may allow for excellent disease control while facilitating prolonged eugonadal testosterone intervals.

Racial and Ethnic Disparities in Opioid Access and Urine Drug Screening Among Older Patients With Poor-Prognosis Cancer Near the End of Life

PURPOSE

To characterize racial and ethnic disparities and trends in opioid access and urine drug screening (UDS) among patients dying of cancer, and to explore potential mechanisms.

METHODS

Among 318,549 non-Hispanic White (White), Black, and Hispanic Medicare decedents older than 65 years with poor-prognosis cancers, we examined 2007-2019 trends in opioid prescription fills and potency (morphine milligram equivalents [MMEs] per day [MMEDs]) near the end of life (EOL), defined as 30 days before death or hospice enrollment. We estimated the effects of race and ethnicity on opioid access, controlling for demographic and clinical factors. Models were further adjusted for socioeconomic factors including dual-eligibility status, community-level deprivation, and rurality. We similarly explored disparities in UDS.

RESULTS

Between 2007 and 2019, White, Black, and Hispanic decedents experienced steady declines in EOL opioid access and rapid expansion of UDS. Compared with White patients, Black and Hispanic patients were less likely to receive any opioid (Black, -4.3 percentage points, 95% CI, -4.8 to -3.6; Hispanic, -3.6 percentage points, 95% CI, -4.4 to -2.9) and long-acting opioids (Black, -3.1 percentage points, 95% CI, -3.6 to -2.8; Hispanic, -2.2 percentage points, 95% CI, -2.7 to -1.7). They also received lower daily doses (Black, -10.5 MMED, 95% CI, -12.8 to -8.2; Hispanic, -9.1 MMED, 95% CI, -12.1 to -6.1) and lower total doses (Black, -210 MMEs, 95% CI, -293 to -207; Hispanic, -179 MMEs, 95% CI, -217 to -142); Black patients were also more likely to undergo UDS (0.5 percentage points; 95% CI, 0.3 to 0.8). Disparities in EOL opioid access and UDS disproportionately affected Black men. Adjustment for socioeconomic factors did not attenuate the EOL opioid access disparities.

CONCLUSION

There are substantial and persistent racial and ethnic inequities in opioid access among older patients dying of cancer, which are not mediated by socioeconomic variables.

Pharmacologic Pain Management: What Radiation Oncologists Should Know

Individuals with cancer experience a host of symptoms, especially when the malignancy is advanced. Pain occurs from the cancer itself or related treatments. Undertreated pain contributes to patient suffering and lack of engagement in cancer-directed therapies. Adequate pain management includes thorough assessment; treatment by radiotherapists or anesthesia pain specialists; anti-inflammatory medications, oral or intravenous opioid analgesics, and topical agents; and attention to the emotional and functional effects of pain, which may involve social workers, psychologists, speech therapists, nutritionists, physiatrists and palliative medicine providers. This review discusses typical pain syndromes arising in cancer patients undergoing radiotherapy and provides concrete recommendations for pain assessment and pharmacologic treatment.

Use of Opioids for Adults With Pain From Cancer or Cancer Treatment: ASCO Guideline

PURPOSE

To provide guidance on the use of opioids to manage pain from cancer or cancer treatment in adults.

METHODS

A systematic review of the literature identified systematic reviews and randomized controlled trials of the efficacy and safety of opioid analgesics in people with cancer, approaches to opioid initiation and titration, and the prevention and management of opioid adverse events. PubMed and the Cochrane Library were searched from January 1, 2010, to February 17, 2022. American Society of Clinical Oncology convened an Expert Panel to review the evidence and formulate recommendations.

RESULTS

The evidence base consisted of 31 systematic reviews and 16 randomized controlled trials. Opioids have primarily been evaluated in patients with moderate-to-severe cancer pain, and they effectively reduce pain in this population, with well-characterized adverse effects. Evidence was limited for several of the questions of interest, and the Expert Panel relied on consensus for these recommendations or noted that no recommendation could be made at this time.

RECOMMENDATIONS

Opioids should be offered to patients with moderate-to-severe pain related to cancer or active cancer treatment unless contraindicated. Opioids should be initiated PRN (as needed) at the lowest possible dose to achieve acceptable analgesia and patient goals, with early assessment and frequent titration. For patients with a substance use disorder, clinicians should collaborate with a palliative care, pain, and/or substance use disorder specialist to determine the optimal approach to pain management. Opioid adverse effects should be monitored, and strategies are provided for prevention and management.Additional information is available at www.asco.org/supportive-care-guidelines.

The Role of Pain Catastrophizing, Emotional Intelligence, and Pain Intensity in the Quality of Life of Cancer Patients with Chronic Pain

Pain catastrophizing (PC) is a negative cognitive distortion to actual or anticipated pain. This study aims to investigate the relationship between pain catastrophizing, emotional intelligence, pain intensity, and quality of life (QoL) in cancer patients with chronic pain. Eighty-nine outpatients with chronic pain attending pain clinics and palliative care units were recruited. Participants were men (42.7%) and women (57.3%) with an average age of 56.44 years (SD = 14.82). Self-report psychological measures were completed, including a measure of emotional intelligence, a standard measure of PC, a scale assessing pain intensity, and a scale measuring QoL. The PC scale was found to assess three correlated yet different dimensions of pain catastrophizing (helplessness, magnification, and rumination). Moreover, as expected, patients with PC scale scores ≥ 30 had lower scores in functional QoL dimensions and higher scores in the fatigue, pain, and insomnia symptom dimensions. Regression analyses demonstrated that PC (B = − 0.391, p = 0.004), pain intensity (B = − 1.133, p < 0.001), and education (B = 2.915, p = 0.017) remained the only significant variables related to QoL, when controlling for demographic and clinical confounders. Regarding mediating effects, PC and pain intensity were jointly found to be significant mediators in the relationship between emotional intelligence and QoL. Results are discussed in the context of the clinical implications regarding interventions designed to improve cancer patients’ quality of life and offer new insight, understanding, and evaluation targets in the field of pain management.

Music Therapy for Pain in Black and White Cancer Patients: A Retrospective Study

CONTEXT

Racial pain disparities present challenges to cancer symptom management. Music therapy has demonstrated benefits for pain and is a promising treatment option for diverse populations due to music's multicultural presence. However, Black cancer patients are under-represented in music therapy trials.

OBJECTIVES

This study compared pain severity, treatment approaches, and responses to music therapy between Black and white cancer patients. The findings will be used to generate hypotheses for future music therapy research to address racial disparities in pain management.

METHODS

We conducted a retrospective program evaluation of Black and white patients who received music therapy at an NCI-Designated Comprehensive Cancer Center. We used the Edmonton Symptom Assessment Scale (ESAS) to assess pain. We abstracted opioid use, music therapy referral reasons, and treatment approaches from the electronic health record.

RESULTS

Among 358 patients, 18% were Black, 42% reported moderate-to-severe pain, and 47% received opioids. Black patients reported higher baseline pain than white patients, but similar proportions of Black and white patients received opioids. Greater proportions of Black patients received music therapy referrals for pain (73% vs. 56%, P = 0.04) and engaged in active techniques (92% vs. 82%, P = 0.04). Black and white patients reported clinically meaningful pain reduction of similar magnitude after music therapy. Black patients discussed spirituality more commonly during music therapy, whereas white patients focused on family bonds.

CONCLUSION

Black and white patients reported clinically meaningful pain reduction through varying music therapy approaches. Our findings may help inform cultural adaptations of music therapy to address racial pain disparities in oncology.

Symptom burden, psychological distress, and symptom management status in hospitalized patients with advanced cancer: a multicenter study in China

BACKGROUND

The management of physical symptoms and psychological distress of cancer patients is an important component of cancer care. The purpose of this study was to evaluate the symptom burden, psychological distress, and management status of hospitalized patients with advanced cancer in China and explore the potential influencing factors of undertreatment and non-treatment of symptoms.

PATIENTS AND METHODS

A total of 2930 hospitalized patients with advanced cancer (top six types of cancer in China) were recruited from 10 centers all over China. Patient-reported MD Anderson Symptom Inventory, Hospital Anxiety and Depression Scale (HADS), and Patient Health Questionnaire-9 (PHQ-9) scales and symptom management-related information were collected and linked with the patient's clinical data. The proportion of patients reporting moderate-to-severe (MS) symptoms and whether they were currently well managed were examined. Multivariable logistic regression models were applied to explore the factors correlated to undertreatment and non-treatment of symptoms.

RESULTS

About 27% of patients reported over three MS symptoms, 16% reported over five, and 9% reported over seven. Regarding psychological distress, the prevalence of HADS-anxiety was 29% and that of PHQ-9 depression was 11%. Sixty-one percent of patients have at least one MS symptom without any treatment. Sex [odds ratio (OR) = 2.238, 95% confidence interval (95% CI) 1.502-3.336], Eastern Cooperative Oncology Group (ECOG; OR = 0.404, 95% CI 0.241-0.676), and whether currently undergoing anticancer treatment (OR = 0.667, 95% CI 0.503-0.886) are the main factors correlated with the undertreatment of symptoms. Age (OR = 1.972, 95% CI 1.263-3.336), sex (OR = 0.626, 95% CI 0.414-0.948), ECOG (OR = 0.266, 95% CI 0.175-0.403), whether currently undergoing anticancer treatment (OR = 0.356, 95% CI 0.249-0.509), and comorbidity (OR = 0.713, 95% CI 0.526-0.966) are the main factors correlated with the non-treatment of symptoms.

CONCLUSIONS

This study shows that hospitalized patients with advanced cancer had a variety of physical and psychological symptoms but lacked adequate management and suggests that a complete symptom screening and management system is needed to deal with this complex problem.

Palliative Care Early in the Care Continuum among Patients with Serious Respiratory Illness: An Official ATS/AAHPM/HPNA/SWHPN Policy Statement

Background: Patients with serious respiratory illness and their caregivers suffer considerable burdens, and palliative care is a fundamental right for anyone who needs it. However, the overwhelming majority of patients do not receive timely palliative care before the end of life, despite robust evidence for improved outcomes. Goals: This policy statement by the American Thoracic Society (ATS) and partnering societies advocates for improved integration of high-quality palliative care early in the care continuum for patients with serious respiratory illness and their caregivers and provides clinicians and policymakers with a framework to accomplish this. Methods: An international and interprofessional expert committee, including patients and caregivers, achieved consensus across a diverse working group representing pulmonary-critical care, palliative care, bioethics, health law and policy, geriatrics, nursing, physiotherapy, social work, pharmacy, patient advocacy, psychology, and sociology. Results: The committee developed fundamental values, principles, and policy recommendations for integrating palliative care in serious respiratory illness care across seven domains: 1) delivery models, 2) comprehensive symptom assessment and management, 3) advance care planning and goals of care discussions, 4) caregiver support, 5) health disparities, 6) mass casualty events and emergency preparedness, and 7) research priorities. The recommendations encourage timely integration of palliative care, promote innovative primary and secondary or specialist palliative care delivery models, and advocate for research and policy initiatives to improve the availability and quality of palliative care for patients and their caregivers. Conclusions: This multisociety policy statement establishes a framework for early palliative care in serious respiratory illness and provides guidance for pulmonary-critical care clinicians and policymakers for its proactive integration.

Evaluating Cancer Pain Characteristics and Treatment Factors in the Emergency Department: A Retrospective Cohort Study

Objectives: To identify patient characteristics and treatment factors of patients presenting to the emergency department (ED) with cancer-related pain that may affect patient outcomes. Methods: We conducted a retrospective cohort study to evaluate adult patients with active cancer, who presented to the ED with a chief complaint of pain between June first, 2012 and January first, 2016. We utilized multivariable logistic regression to evaluate the association of several exposure variables, including disease and demographic characteristics, primary pain site, and treatment methods, on ED disposition and revisit rate. Results: We included 483 patients with active cancer with a chief complaint of pain. Patients with severe pain on arrival tended to be younger than those who did not present with severe pain (median: 58 vs 62 respectively, OR 8.0 p < 0.01). Patients with high ECOG scores (3-4) with severe pain on arrival (≥7 out of 10) had less improvement in their pain than the rest of our cohort (OR 8.4, p < 0.01). Also, those with musculoskeletal pain had significantly less improvement in reported pain than all other pain types (delta pain −2.1 vs −3.4, OR 2.3, p = 0.025) Long delays in initial analgesic administration were associated with increased rates of subsequent admission (OR 3.4) [p = 0.014]. Although opioid analgesics led to greater decreases in pain than non-opioid analgesics, patients treated with opioids were more likely to be admitted (43% vs 34.5% AOR 1.51, p = 0.048). Conclusion: Our study showed that delays in analgesic administration, poor functional status, and the presence of musculoskeletal (MSK) pain significantly influenced outcomes for this patient cohort. These findings suggest the development of specific protocols and tools to address cancer-related pain in the ED may be necessary.

Feasibility of a pharmacist-led symptom monitoring and management intervention to improve breast cancer endocrine therapy adherence

BACKGROUND

Adjuvant endocrine therapy (AET) for breast cancer reduces mortality, but one-third to one-half of patients discontinue it early or are nonadherent.

OBJECTIVE

We developed a pilot single-site study of patients with evidence of early nonadherence to AET to assess the feasibility of a novel, clinical pharmacist-led intervention targeting symptom and medication management.

METHODS

Patients with prescription fill records showing nonadherence were enrolled in a single-arm feasibility study. Automated reminders were sent by e-mail or text with a link to symptom monitoring assessments weekly for 1 month and monthly until 6 months. Clinical oncology pharmacists used guideline-based symptom management and other medication management tools to support adherence and ameliorate symptoms reported on the assessments. Patient-reported outcome assessments included physical, mental, and social health domains and self-efficacy to manage symptoms and medications. Feasibility outcomes included completion of symptom reports and pharmacist recommendations.

RESULTS

Of 19 participants who were nonadherent who enrolled and completed initial assessments, 18 completed all final study procedures, with 14 completing all assessments and no patient missing more than 3 assessments. All 18 participants reported at least one of 3 symptom types, and the majority reported attempting pharmacist recommendations. Patient-reported measures of physical, mental, and social health and self-efficacy improved, and 44% of the patients became adherent.

CONCLUSION

An intervention using pharmacists in an oncology practice to systematically monitor and manage symptoms shows promise to reduce symptoms, enhance support and self-efficacy, and improve adherence to AET.

Do racial and ethnic disparities lead to the undertreatment of pain? Are there solutions?

PURPOSE OF REVIEW

The current review aims to empower anesthesiologists, specifically pain medicine specialists, to become leaders in ensuring equitable care.

RECENT FINDINGS

Disparities in both acute and chronic pain medicine lead to increased morbidity for patients of color. Gaps in care include misdiagnosis or under diagnosis of chronic pain disease states, undertreatment of sickle cell disease and other conditions that are common in minorities, under prescription of opioids, and lack of access to novel opioid sparing treatments. While the causes of these disparities are multifactorial, care team implicit bias and lack of representation are two of the major factors. Solutions are challenging, but the authors suggest an inside out solution. We believe that this practice will have far-reaching downstream effects, including improving diversity in our field and quality of care for our patients.

SUMMARY

The current article reviews disparities in both acute and chronic pain treatment for underrepresented racial and ethnic minorities in the United States. The authors examine whether implicit bias and lack of representation are a contributing factor for these disparities. Lastly, we will discuss potential solutions.

Impact of NCCN Guideline Adherence in Adult Cancer Pain on Length of Stay

To improve the management of cancer related pain, the National Comprehensive Cancer Network (NCCN) publishes the Adult Cancer Pain guideline on an annual basis. However, a large majority of oncology patients still report inadequate pain control. Single-center, retrospective cohort study of adult patients admitted for uncontrolled pain or pain crisis between 3/1/19 and 06/30/20 were assigned to cohorts of either adherent or non-adherent to NCCN guideline recommendations for management of pain crises based on their initial opioid orders. Patients must have reported a pain score >/= 4 and received at least one dose of opioids within 24 hours upon admission. The length of stay (LOS), pain scores, and naloxone administration were compared between both groups. Patients in the adherent group had a shorter median LOS (3.7 days [range: 1 to 18.93] vs 5.4 days [range: 1.45 to 19.64 days], p = 0.04). Patients that received lower doses than recommended had longer LOS compared to adherent group (6.1 vs. 3.7 days; p = 0.009). When adjusted for confounders, this significance did not remain. The lowest reported pain score within 24 hours of admission was lower in the adherent group (median 3 vs 4, p = 0.04). Predictors of LOS included opioid tolerance and a pain or palliative care consult. Adherence to NCCN guidelines for acute pain crisis management in adult patients with cancer remains poor. Patients who received guideline adherent initial opioid regimens demonstrated a trend toward a shorter LOS. Opioid-tolerant patient outcomes remain inadequate; appropriate pain management for these patients need to improve.

Does ethnicity affect pain management for people with advanced disease? A mixed methods cross-national systematic review of 'very high' Human Development Index English-speaking countries

BACKGROUND

Racial disparities in pain management have been observed in the USA since the 1990s in settings such as the emergency department and oncology. However, the palliative care context is not well described, and little research has focused outside of the USA or on advanced disease. This review takes a cross-national approach to exploring pain management in advanced disease for people of different racial and ethnic groups.

METHODS

Mixed methods systematic review. The primary outcome measure was differences in receiving pain medication between people from different racial and ethnic groups. Five electronic databases were searched. Two researchers independently assessed quality using JBI checklists, weighted evidence, and extracted data. The quantitative findings on the primary outcome measure were cross-tabulated, and a thematic analysis was undertaken on the mixed methods studies. Themes were formulated into a conceptual/thematic matrix. Patient representatives from UK ethnically diverse groups were consulted. PRISMA 2020 guidelines were followed.

RESULTS

Eighteen papers were included in the primary outcome analysis. Three papers were rated 'High' weight of evidence, and 17/18 (94%) were based in the USA. Ten of the eighteen (56%) found no significant difference in the pain medication received between people of different ethnic groups. Forty-six papers were included in the mixed methods synthesis; 41/46 (89%) were based in the USA. Key themes: Patients from different ethnically diverse groups had concerns about tolerance, addiction and side effects. The evidence also showed: cultural and social doctor-patient communication issues; many patients with unmet pain management needs; differences in pain assessment by racial group, and two studies found racial and ethnic stereotyping.

CONCLUSIONS

There was not enough high quality evidence to draw a conclusion on differences in receiving pain medication for people with advanced disease from different racial and ethnic groups. The mixed methods findings showed commonalities in fears about pain medication side effects, tolerance and addiction across diverse ethnic groups. However, these fears may have different foundations and are differently prioritised according to culture, faith, educational and social factors. There is a need to develop culturally competent pain management to address doctor-patient communication issues and patients' pain management concerns.

Effect Evaluation of Electronic Health PDCA Nursing in Treatment of Childhood Asthma with Artificial Intelligence

Asthma in children has a long duration and is prone to recurring attacks. Children will feel chest tightness, shortness of breath, cough, and difficulty breathing when they are onset, which has a serious impact on their health. Clinical nursing is of great significance in the treatment of childhood asthma. At present, the electronic health PDCA nursing model is widely used in clinical nursing as a common and effective nursing method. Therefore, it is very important to evaluate the efficacy of the PDCA nursing model in the treatment of childhood asthma. With the development of artificial intelligence, artificial intelligence can be used to evaluate the effect of the PDCA nursing model in the treatment of childhood asthma. The BP network can effectively perform data training and discrimination, but its training efficiency is low, and it is easily affected by initial weights and thresholds. Aiming at this defect, this work uses the genetic simulated annealing (GSA) algorithm to improve it. In view of the problems that the genetic algorithm falls into local minimum and simulated annealing algorithm has a slow convergence speed, the improved genetic simulated annealing algorithm is used to optimize the BP neural network, and an improved genetic simulated annealing BP network (IGSA-BP) is proposed. The algorithm not only reduces the problem that the BP network has an influence on initial weight and threshold on the algorithm but also improves the population diversity and avoids falling into local optimum by improving the crossover and mutation probability formula and improving Metropolis criterion. The proposed method has more efficient performance.

Patients' Satisfaction with Breakthrough Cancer Pain Therapy: A Secondary Analysis of IOPS-MS Study

Background

Cancer pain is one of the most important symptoms for patients. Pharmacological control is central for clinical management and to ensure well-being. In cancer patients, the management of breakthrough cancer pain (BTcP) is also crucial. This study aims to identify factors that can predict patients' satisfaction with pain relief for BTcP.

Methods

This was a secondary analysis of the IOPS-MS study, a large, observational, multicenter, national study where thirty-two Italian centers were involved to explore BTcP management. Clinical and pathologic features were recorded, as well as the patients' degree of satisfaction with BTcP medications classified as dissatisfied (not or indifferent satisfied) versus satisfied (or very satisfied). Frequency distributions and the chi-squared test of independence were performed. A multivariate model was carried out by selecting significant variables upon univariate analysis using logistic regression.

Results

From the original 4016 patients enrolled, 3840 were available for the study purpose. Seventy-one per cent of patients declared satisfaction with BTcP medications. Young age [odds ratio (OR) 1.29 (95% confidence interval, CI: 1.12-1.50)], non-metastatic cancer stage [OR 1.53 (95% CI: 1.22-1.91)], high Karnofsky performance status [OR 1.63 (95% CI:1.33-1.99)], the absence of anticancer treatment [OR 1.42 (95% CI: 1.19-1.69)], the NSAIDs/paracetamol use for background pain [OR 1.56 (95% CI: 1.34-1.82)] and a high BTcP interference in activities of daily living [OR 2.34 (95% CI: 1.81-3.01)] resulted positively correlated with dissatisfaction in the multivariate analyses. Also, the setting of care was related to difference in BTcP therapy satisfaction.

Conclusion

This study proposes several key points to be considered in the pharmacological management of BTcP, useful to ensure patients' satisfaction and optimal quality of life.

Improving Equity in Cancer Care in the Face of a Public Health Emergency

ABSTRACT

Cancer health disparities have been well documented among different populations in the United States for decades. While the cause of these disparities is multifactorial, the COVID-19 pandemic has highlighted the structural barriers to health and health care and the gaps in public health infrastructure within the United States. The most long-standing inequities are rooted in discriminatory practices, current and historical, which have excluded and disenfranchised many of the most vulnerable populations in the nation. These systemic barriers are themselves a public health crisis, resulting in increased mortality rates in communities of color from both COVID-19 and cancer. While implementing programs to temporarily improve cancer equity locally or regionally is laudable, it is imperative to develop a public health strategy focused on alleviating the root causes of health inequities to improve the health and well-being of every citizen and ensure readiness for the next public health emergency.

A living systematic review to assess the analgesic undertreatment in cancer patients

This living, systematic review aims to provide an updated summary of the available evidence on pain undertreatment prevalence in patients with cancer; correlations with some potential determinants and confounders were also carried out. We updated a systematic review published in 2014, including observational and experimental studies reporting the use of the pain management index (PMI) in adults with cancer and pain, from 2014 to 2020. We conducted searches in PubMed/MEDLINE, Embase, and Google Scholar. We performed univariate and multivariable regression analyses to describe the relationship between PMI and a list of potential explanatory variables. Twenty new papers were identified, yielding a total sample size of 66 studies. The proportion of patients classified as undertreated according to the year of study publication shows a higher decrease from 1994 to 2013 (-13% as relative change) than the most recent years 2014-2020 (-11%). The quality of the included studies has increased over the years (from 80% to 93%). At the multivariable analysis, a statistically significant relationship was confirmed between undertreatment and the year of the publication of the study and with a low-medium economic level of the countries where the studies were conducted. Despite the improvement when compared to the period 1994-2000,-still about 40% of the cases identified received an analgesic treatment inadequate to the intensity of pain, according to the PMI. Despite its intrinsic limitations, PMI continues to be widely used and it could allow a continuous monitoring of pain management across a different mix of studies and patients.

Worst Pain Severity Profiles of Oncology Patients Are Associated With Significant Stress and Multiple Co-Occurring Symptoms

Little is known about the associations between pain, stress, and co-occurring symptoms in oncology patients. Purpose was to identify subgroups of patients with distinct worst pain profiles and evaluate for differences among the subgroups in demographic and clinical characteristics, as well as stress and symptom scores. Oncology outpatients (n = 1305) completed questionnaires prior to their second or third chemotherapy cycle. Worst pain intensity was assessed 6 times over 2 chemotherapy cycles using a 0 to 10 numeric rating scale. The 371 patients (28.4%) who had ≤1 occurrence of pain over the 6 assessments were classified as the None class. For the remaining 934 patients whose data were entered into the latent profile analysis, 3 distinct worst pain profiles were identified (ie Mild [12.5%], Moderate [28.6%], Severe [30.5%]). Compared to None class, Severe class had fewer years of education and a lower annual income; were less likely to be employed and married; less likely to exercise on a regular basis, had a higher comorbidity burden, and a worse functional status. Compared to None class, Severe class reported higher levels of general, disease-specific, and cumulative life stress and lower levels of resilience, as well as higher levels of depressive symptoms, anxiety, fatigue, sleep disturbance, and cognitive dysfunction. This study is the first to identify distinct worst pain profiles in a large sample of oncology patients receiving chemotherapy and associated risk factors. PERSPECTIVE: Unrelieved pain remains a significant problem for oncology patients receiving chemotherapy. High levels of stress and co-occurring symptoms contribute to a more severe pain profile in these patients.

Compassion Inequities and Opioid Use Disorder: A Matched Case-Control Analysis Examining Inpatient Management of Cancer-Related Pain for Patients With Opioid Use Disorder

CONTEXT

The opioid epidemic spurred guidelines intended to reduce inappropriate prescribing. Although acute cancer-related pain was excluded from these recommendations, studies demonstrate reduced opioid prescribing for patients hospitalized with advanced cancer.

OBJECTIVES

We performed a matched case-control analysis to determine how a history of opioid use disorder (OUD) affects inpatient management of cancer pain.

METHODS

Charts of patients with OUD admitted for cancer pain from 2015-2020 were retrospectively reviewed. Hospitalizations were matched 1:1 by patient age and sex. Home milligram-morphine equivalent per day (MME/day) was calculated from the home medication list. Admission MME/day was the average MME/day administered during hospitalization.

RESULTS

A total of 80 hospitalizations (40:40) were matched for 25 patients with a history of OUD and 31 patients with no history of OUD. Cancer was metastatic/relapsed for 70% of admissions. The median overall survival was 2.3 months (95% CI 0-5.21, P = 0.13). Patients with OUD had a significantly lower change from Home to Admission MME/day (-3 vs. 37, P < 0.01) and were less likely to have any increase in Admission MME/day (OR 0.1, 95% CI 0.02-0.43, P < 0.01). When considering opioids administered after pain specialty consultation, there was no difference between groups.

CONCLUSION

Our results suggest that patients with OUD receive lower quality inpatient management of cancer-related pain. Provider education and early involvement of pain specialists are crucial in delivering equitable and compassionate end-of-life care for patients with OUD.

US Trends in Opioid Access Among Patients With Poor Prognosis Cancer Near the End-of-Life

PURPOSE

Heightened regulations have decreased opioid prescribing across the United States, yet little is known about trends in opioid access among patients dying of cancer.

METHODS

Among 270,632 Medicare fee-for-service decedents with poor prognosis cancers, we used part D data to examine trends from 2007 to 2017 in opioid prescription fills and opioid potency (morphine milligram equivalents per day [MMED]) near the end-of-life (EOL), defined as the 30 days before death or hospice enrollment. We used administrative claims to evaluate trends in pain-related emergency department (ED) visits near EOL.

RESULTS

Between 2007 and 2017, the proportion of decedents with poor prognosis cancers receiving ≥ 1 opioid prescription near EOL declined 15.5% (relative percent difference [RPD]), from 42.0% (95% CI, 41.4 to 42.7) to 35.5% (95% CI, 34.9 to 36.0) and the proportion receiving ≥ 1 long-acting opioid prescription declined 36.5% (RPD), from 18.1% (95% CI, 17.6 to 18.6) to 11.5% (95% CI, 11.1 to 11.9). Among decedents receiving opioids near EOL, the mean daily dose fell 24.5%, from 85.6 MMED (95% CI, 82.9 to 88.3) to 64.6 (95% CI, 62.7 to 66.6) MMED. Overall, the total amount of opioids prescribed per decedent near EOL (averaged across those who did and did not receive an opioid) fell 38.0%, from 1,075 morphine milligram equivalents per decedent (95% CI, 1,042 to 1,109) to 666 morphine milligram equivalents per decedent (95% CI, 646 to 686). Simultaneously, the proportion of patients with pain-related ED visits increased 50.8% (RPD), from 13.2% (95% CI, 12.7 to 13.6) to 19.9% (95% CI, 19.4 to 20.4). Sensitivity analyses demonstrated similar declines in opioid utilization in the 60 and 90 days before death or hospice, and suggested that trends in opioid access were not confounded by secular trends in hospice utilization.

CONCLUSION

Opioid use among patients dying of cancer has declined substantially from 2007 to 2017. Rising pain-related ED visits suggests that EOL cancer pain management may be worsening.

Opioid epidemic and prescribing in hospice and palliative care: a review of the literature

BACKGROUND

Rising rates of opioid abuse worldwide have led to the implementation of policies to curb opioid prescribing. It is unknown what impact these policies have on prescribing within the setting of hospice and palliative care.

OBJECTIVES

To determine the current state of the science of opioid prescribing in hospice and palliative care in relation to the opioid epidemic and associated policies.

METHODS

A systematic integrative literature review was conducted using the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, ProQuest Central and SCOPUS.

RESULTS

Most of the existing literature examines physician perspectives related to opioid prescribing in primary care settings. Ample evidence exists that policies can and do affect rates of opioid prescribing in specialties outside of hospice and palliative care. There is limited evidence to suggest how these policies affect opioid prescribing in hospice and palliative care. However, the available evidence suggests that opioids are necessary in hospice and palliative care in order to manage pain.

CONCLUSION

Further research is necessary to examine the possible negative impact of the opioid epidemic on opioid prescribing in hospice and palliative care.

Racial, Ethnic, and Socioeconomic Discrepancies in Opioid Prescriptions Among Older Patients With Cancer

PURPOSE

Minority race and lower socioeconomic status are associated with lower rates of opioid prescription and undertreatment of pain in multiple noncancer healthcare settings. It is not known whether these differences in opioid prescribing exist among patients undergoing cancer treatment.

METHODS AND MATERIALS

This observational cohort study involved 33,872 opioid-naive patients of age > 65 years undergoing definitive cancer treatment. We compared rates of new opioid prescriptions by race or ethnicity and socioeconomic status controlling for differences in baseline patient, cancer, and treatment factors. To evaluate downstream impacts of opioid prescribing and pain management, we also compared rates of persistent opioid use and pain-related emergency department (ED) visits.

RESULTS

Compared with non-Hispanic White patients, the covariate-adjusted odds of receiving an opioid prescription were 24.9% (95% CI, 16.0 to 33.9, P < .001) lower for non-Hispanic Blacks, 115.0% (84.7 to 150.3, P < .001) higher for Asian-Pacific Islanders, and not statistically different for Hispanics (-1.0 to 14.0, P = .06). There was no significant association between race or ethnicity and persistent opioid use or pain-related ED visits. Patients living in a high-poverty area had higher odds (53.9% [25.4 to 88.8, P < .001]) of developing persistent use and having a pain-related ED visit (39.4% [16.4 to 66.9, P < .001]).

CONCLUSION

For older patients with cancer, rates of opioid prescriptions and pain-related outcomes significantly differed by race and area-level poverty. Non-Hispanic Black patients were associated with a significantly decreased likelihood of receiving an opioid prescription. Patients from high-poverty areas were more likely to develop persistent opioid use and have a pain-related ED visit.

Cost-Utility of Group Versus Individual Acupuncture for Cancer-Related Pain Using Quality-Adjusted Life Years in a Noninferiority Trial

Introduction: Individual acupuncture (AP) is the gold standard method of AP delivery for cancer-related pain; however, costs can be prohibitive. Group AP allows four to six patients to be treated in a single session. This study sought to examine the cost-utility of group AP compared with individual AP from a patient perspective. Materials and Methods: Effectiveness and cost data from a noninferiority randomized trial of group versus individual AP for cancer-related pain were used. In the trial, 74 patients were randomly assigned to individual or group AP treatments twice per week for 6 weeks. The EuroQol five-dimension five level questionnaire (EQ-5D-5L) was used to assess health-related quality of life, and the EQ-5D Utility Index was used as a composite measure constituted of five domains (mobility, self-care, usual activities, anxiety-depression, and pain-discomfort). Linear mixed models were used to compare the change in EQ-5D-5L states pre-post intervention between the two arms. A cost-utility analysis was performed in terms of the incremental costs per additional quality-adjusted life year (QALY) gained. Results: Group AP participants experienced more significant relief in the pain-discomfort subscale of the EQ-5D-5L measure compared with individual AP participants (group × time, F = 6.18; p = 0.02). The effect size on pain-discomfort for group AP (d = 0.80) was higher than that of individual AP (d = 0.34). There were no significant differences between the two study arms for other subscales of the EQ-5D-5L over time. QALYs at 6 weeks were slightly higher for group AP (0.020) compared with individual AP (0.007) leading to an incremental QALY gained by the group arm of 0.013, but this difference was not statistically significant (p = 0.07). The cost of delivering AP treatment for the group arm over 6 weeks ($201.25) was nearly half of the individual arm ($400). Conclusions: Group AP was superior to individual AP in cancer patients. These findings have implications for the use of group AP in low-resource settings and in health care systems where AP for cancer patients is not covered by public health insurance.

Adaptations to Acupuncture and Pain Counseling Implementation in a Multisite Pragmatic Randomized Clinical Trial

Objectives: As part of a pragmatic effectiveness trial of integrative pain management among inpatients with cancer, the authors sought to understand the clinical context and adaptations to implementation of two study interventions, acupuncture and pain counseling (i.e., pain education and coping skills). Design: The larger study uses a 2 × 2 factorial design with inpatients randomized to: (1) usual care (UC), (2) UC with acupuncture, (3) UC with pain counseling, and (4) UC with acupuncture and pain counseling. The study is being conducted in two hospitals (one academic and one public) and three languages (Cantonese, English, and Spanish). The authors conducted a process evaluation by interviewing study interventionists. Analysis included deductive coding to describe context, intervention, implementation, and inductive thematic coding related to intervention delivery. Results: Interviewees included seven acupuncturists and four pain counselors. Qualitative themes covered adaptations and recognizing site-specific differences that affected implementation. Interventionists adhered closely to protocols and made patient-centered adaptations that were then standardized in broader implementation (e.g., including caregivers in pain counseling sessions; working in culturally nuanced ways with non-English-speaking patients). The public hospital included more patients with recent diagnoses and advanced disease, more ethnically and linguistically diverse patients, less continuity of staffing, and shared patient rooms. At the academic medical center, more patients were familiar with integrative therapies and all were located in single rooms. Providing acupuncture to hospital staff was a key strategy to establish trust, experientially explain the intervention, and create camaraderie and staff buy-in. Conclusions: Providing nonpharmacologic interventions for a pragmatic trial requires adapting to a range of clinical factors. Site-specific factors included greater coordination and resources needed for successful implementation in the public hospital. The authors conclude that adaptation to context and individual patient needs can be done without compromising intervention fidelity and that intervention design should apply principles such as centering at the margins to reduce participation barriers for diverse patient populations.

Opioid use by cancer status and time since diagnosis among older adults enrolled in the Prostate, Lung, Colorectal, and Ovarian screening trial in the United States

BACKGROUND

Dosing limits in opioid clinical practice guidelines in the United States are likely misapplied to cancer patients, however, opioid use may be difficult to ascertain as they are largely excluded from opioid use studies.

METHODS

The primary objective was to determine whether cancer patients were more likely to be chronic opioid users after diagnosis. We described prescription opioid use among U.S. older adult cancer patients during two time periods, within 2 years of diagnosis (short-term) and at least 2 years beyond diagnosis (long-term), compared to those without cancer (controls). Among participants in the Prostate, Lung, Colorectal, and Ovarian (PLCO) screening trial with linkages to Medicare Part D data during 2011-2015, we used multivariable logistic regression to estimate the association between cancer diagnosis and opioid use outcomes controlling for demographics. The primary outcome of opioid use was measured with the following metrics: Any opioid use, chronic use (90 consecutive days supply of opioid use while allowing for a 7-day gap between refills), high use (average daily morphine equivalent (MME) ≥120 mg for any 90-day period), and total MME dose above 2,000 mg (MME₂₀₀₀ ).

RESULTS

The short-term cohort included 1,491 cancer patients and 24,930 controls. Any use in the 2-year post-diagnosis period was higher among cancer patients OR 3.3 (95% CI: 3.0-3.7). Chronic use rates were similar by cancer status (4.6% vs. 3.8% for cases and controls, respectively). The long-term cohort included 4,377 cancer patients and 27,545 controls. Rates of any use were similar among cancer patients and controls (63% vs. 59%).

CONCLUSIONS

Any opioid use was similar among long-term cancer survivors compared to controls, but differed among short-term survivors for any opioid use and marginally for chronic opioid use.

Effect of cyclooxygenase inhibitor use on immunotherapy efficacy in non-small cell lung cancer

BACKGROUND

A synergistic effect of cyclooxygenase inhibitors (COX-I) and immune checkpoint inhibitors (ICIs) has been suggested. However, the impact of COX-I on the efficacy of ICIs is unclear. Here, we aimed to evaluate the relationship between COX-I use and the efficacy of ICI in patients with non-small cell lung cancer (NSCLC).

METHODS

We retrospectively reviewed NSCLC patients who received ICI monotherapy. We defined COX-I use as regular use of COX-I other than low-dose aspirin during the initiation of ICIs to the first evaluation of efficacy. The efficacy of ICIs was evaluated with response rate (RR), disease control rate (DCR), progression free survival (PFS), and overall survival (OS). Differences in baseline characteristics by COX-I use were controlled by using an inverse probability of treatment weighting (IPW) adjusted analysis.

RESULTS

A total of 198 patients with NSCLC received ICIs; 128, 50, and 20 patients received nivolumab, pembrolizumab, and atezolizumab, respectively; there were 65 (32.8%) COX-I users. While there was no significant difference in RR (15.4% vs. 13.5%; p = 0.828), DCR (41.5% vs. 49.6%; p = 0.294), PFS (median, 2.69 vs. 3.68 months; 95% confidence intervals [CI], 1.77-5.19 vs. 2.20-4.60 months; p = 0.630), COX-I users had significantly shorter OS than non-COX-I users (median, 6.08 vs. 16.10 months; 95% CI: 3.78-11.66 vs. 9.49-19.68 months; p = 0.003). On IPW adjusted analysis, there was no significant difference in OS (median, 7.85 vs. 15.11 months; 95% CI: 5.03-14.92 vs. 9.49-19.32 months; p = 0.081).

CONCLUSIONS

There was no additional or negative impact of COX-I use on the efficacy of ICIs in NSCLC.

Psychoeducational Nursing Intervention for Symptom Management in Cancer Patients: A Randomized Clinical Trial

Objective

The objective of this study was to assess the effects of a psychoeducational intervention upon symptom control and quality of life (QoL) among cancer patients.

Methods

This was an open randomized clinical trial (RCT) conducted at the Cancer Institute of the State of São Paulo. The RCT comprised 107 outpatients in chemotherapy or radiation for malignant neoplasms. Participants were randomized to control group (usual treatment) or intervention group (IG) (psychoeducational intervention) with assessments at baseline and upon completion of the intervention. Sociodemographic information, clinical data, QoL, functionality, and symptoms were assessed. This trial is registered with the Brazilian Clinical Trials Registry number RBR-9337nv. A mixed-effects model was applied to compare the effects of the intervention between the groups.

Results

The most frequent symptoms were fatigue (76.6%), insomnia (47.7%), pain (42.1%), and loss of appetite (37.4%). The symptom intensity analysis suggests that insomnia was the strongest symptom, followed by fatigue, loss of appetite, and pain. The IG experienced a significant improvement in terms of loss of appetite (P = 0.002) and a tendency toward less insomnia (P = 0.053).

Conclusions

The intervention significantly reduced appetite loss in cancer patients. Despite no effects observed in global QoL or functionality, the intervention yielded a tendency to improve insomnia, and this outcome should be investigated in future studies.

Validation of an oncology-specific opioid risk calculator in cancer survivors

BACKGROUND

Clinical guidelines recommend that providers risk-stratify patients with cancer before prescribing opioids. Prior research has demonstrated that a simple cancer opioid risk score might help identify to patients with cancer at the time of diagnosis with a high likelihood of long-term posttreatment opioid use. This current project validates this cancer opioid risk score in a generalizable, population-based cohort of elderly cancer survivors.

METHODS

This study identified 44,932 Medicare beneficiaries with cancer who had received local therapy. Longitudinal opioid use was ascertained from Medicare Part D data. A risk score was calculated for each patient, and patients were categorized into low-, moderate-, and high-risk groups on the basis of the predicted probability of persistent opioid use. Model discrimination was assessed with receiver operating characteristic curves.

RESULTS

In the study cohort, 5.2% of the patients were chronic opioid users 1 to 2 years after the initiation of cancer treatment. The majority of the patients (64%) were at low risk and had a 1.2% probability of long-term opioid use. Moderate-risk patients (33% of the cohort) had a 5.6% probability of long-term opioid use. High-risk patients (3.5% of the cohort) had a 75% probability of long-term opioid use. The opioid risk score had an area under the receiver operating characteristic curve of 0.869.

CONCLUSIONS

This study found that a cancer opioid risk score could accurately identify individuals with a high likelihood of long-term opioid use in a large, generalizable cohort of cancer survivors. Future research should focus on the implementation of these scores into clinical practice and how this could affect prescriber behavior and patient outcomes.

LAY SUMMARY

A novel 5-question clinical decision tool allows physicians treating patients with cancer to accurately predict which patients will persistently be using opioid medications after completing therapy.

Patterns of opioid use in older people diagnosed with cancer in New South Wales, Australia

PURPOSE

Opioids provide effective analgesia for most cancer patients, but little is known about individual-level opioid use after cancer diagnosis. We examined the patterns of and factors associated with opioid use in older people diagnosed with cancer.

METHODS

We used the Department of Veterans' Affairs (DVA) client data linked with the New South Wales (NSW) Cancer Registry and the Repatriation Pharmaceutical Benefits Scheme data. We included people aged ≥65 years diagnosed with cancer in NSW, Australia in 2005 to 2015. We examined patterns of opioid use in the 12 months after cancer diagnosis and used cause-specific hazards models to examine factors associated with opioid use.

RESULTS

Of 13 527 people diagnosed with cancer, 51% were dispensed opioids after their diagnosis. We observed the highest proportions of use in people diagnosed with pancreas, liver, or lung cancers. Opioid use was associated with female sex, younger age, more advanced degree of cancer spread, opioid use before cancer diagnosis, and multimorbidity. Forty-four percentages of all people dispensed opioids had a history of opioid use in the 12 months before their cancer diagnosis; these people had higher median number of different opioids and opioid dispensings, and a shorter time to first opioid dispensing than opioid-naive people.

CONCLUSION

Our study suggests that many older cancer patients were dispensed opioids before their cancer diagnosis. Previously opioid-treated people had more intense opioid use patterns after diagnosis than opioid-naïve people. Acknowledging the history of opioid use is important as it may complicate pain treatment in clinical practice.

Clinical Utility and User Perceptions of a Digital System for Electronic Patient-Reported Symptom Monitoring During Routine Cancer Care: Findings From the PRO-TECT Trial

PURPOSE

There is increasing interest in implementing digital systems for remote monitoring of patients' symptoms during routine oncology practice. Information is limited about the clinical utility and user perceptions of these systems.

METHODS

PRO-TECT is a multicenter trial evaluating implementation of electronic patient-reported outcomes (ePROs) among adults with advanced and metastatic cancers receiving treatment at US community oncology practices (ClinicalTrials.gov identifier: NCT03249090). Questions derived from the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) are administered weekly by web or automated telephone system, with alerts to nurses for severe or worsening symptoms. To elicit user feedback, surveys were administered to participating patients and clinicians.

RESULTS

Among 496 patients across 26 practices, the majority found the system and questions easy to understand (95%), easy to use (93%), and relevant to their care (91%). Most patients reported that PRO information was used by their clinicians for care (70%), improved discussions with clinicians (73%), made them feel more in control of their own care (77%), and would recommend the system to other patients (89%). Scores for most patient feedback questions were significantly positively correlated with weekly PRO completion rates in both univariate and multivariable analyses. Among 57 nurses, most reported that PRO information was helpful for clinical documentation (79%), increased efficiency of patient discussions (84%), and was useful for patient care (75%). Among 39 oncologists, most found PRO information useful (91%), with 65% using PROs to guide patient discussions sometimes or often and 65% using PROs to make treatment decisions sometimes or often.

CONCLUSION

These findings support the clinical utility and value of implementing digital systems for monitoring PROs, including the PRO-CTCAE, in routine cancer care.

Testing Symptom Severity Thresholds and Potential Alerts for Clinical Intervention in Patients With Cancer Undergoing Chemotherapy

PURPOSE

Symptom monitoring is attracting attention as a way to improve adherence to cancer therapy, reduce treatment-related toxicities, and possibly improve overall survival. How reporting thresholds affect symptom alert generation and clinical outcomes is poorly understood.

PATIENTS AND METHODS

We analyzed data from 38 US health care institutions collected for the prospective Eastern Cooperative Oncology Group-American College of Radiology Imaging Network E2Z02 Symptom Outcomes and Practice Patterns study. Participants were outpatients receiving chemotherapy for breast (n = 642), colorectal (n = 486), or lung cancer (n = 340) who rated symptom severity using the MD Anderson Symptom Inventory at 2 assessment points 1 month apart. Percentages of patients with pain, dyspnea, fatigue, or distress at different thresholds (score of 4-7 on a 0-10 scale) were compared. The percentage of patients whose performance status had worsened at follow-up was used to estimate risk for missing clinically important symptom data by using higher severity thresholds.

RESULTS

At the guideline-recommended threshold of ≥ 4, suprathreshold rates were 60% for any of the 4 symptoms at the initial survey; performance status worsened at follow-up for 27% of all patients with any symptom rated ≥ 4 at the initiate survey. When the threshold was increased to ≥ 7, approximately half of patients (51%) with worsened performance status were not identified.

CONCLUSION

The burden to clinicians from an alert threshold of ≥ 4 (per many current guidelines) would be substantial. However, setting higher alert thresholds may miss a large percentage of patients who need clinical intervention. These results may inform resource planning when implementing electronic symptom screening at an institutional or practice level.

Feasibility and delivery of patient-reported outcomes in clinical practice among racially diverse bladder and prostate cancer patients

OBJECTIVE

To assess the feasibility of enrollment and collecting patient-reported outcome (PRO) data as part of routine clinical urologic care for bladder and prostate cancer patients and examine overall patterns and racial variations in PRO use and symptom reports over time.

SUBJECTS/PATIENTS AND METHODS

We recruited 76 patients (n = 29 Black and n = 47 White) with prostate or bladder cancer at a single, comprehensive cancer center. The majority of prostate cancer patients had intermediate risk (57%) disease and underwent either radiation or prostatectomy. Over half (58%) of bladder cancer patients had muscle invasive disease and underwent cystectomy. Patients were asked to complete PRO symptom surveys using their preferred mode [web- or phone-based interactive voice response (IVR)]. Symptom summary reports were shared with providers during visits. Surveys were completed at 3 time points and assessed urinary, sexual, gastrointestinal, anxiety/depression, and sleep symptoms. Feasibility of enrollment and survey completion were calculated, and linear mixed effects models estimated differences in outcomes by race and time.

RESULTS

Sixty three percent of study participants completed all PRO measures at all 3 time points. Black patients were more likely to select IVR as their survey mode (40% vs. 13%, P < 0.05), and less likely to complete all surveys (55% vs. 74%, P = 0.13). Patients using IVR were also less likely to complete all surveys (41% vs. 69%, P = 0.046).

CONCLUSIONS

Reported preferences for survey mode and completion rates differ by race, which may influence survey completion rates and highlight potential obstacles for equitable implementation of PROs into clinical care.

Effectiveness of Education Program on Nursing Knowledge and Attitude toward Pain Management

Objective:

Nurses have an integral role in pain assessment and management. Adequate knowledge and positive attitudes toward pain management are essential to provide high-quality nursing care for cancer pain. The purposes of this study are to evaluate nurses' knowledge and attitude toward cancer-related pain and to assess the effectiveness of a pain management education program on nurses' knowledge and attitude toward pain.

Methods:

A quantitative, experimental design was used.

Results:

The total number of participants who were surveyed at three measurement points was 131, with a completion rate of 87.3%. Findings revealed that the score of knowledge and attitude toward cancer-related pain ranged from 14 to 35, with a mean of 23.6 (standard deviation [SD] = 4.38). The mean scores of the intervention group and the control group at two measurement points regarding knowledge and attitude toward cancer-related pain were 32.7 (SD = 2.8) and 32.8 (SD = 4.3) and 23 (SD = 5.5) and 22.2 (SD = 3.8), respectively. There were significant differences at three measurement points among the intervention group (F = 114.3, P < 0.0005). There were no differences in the three measurement points among the control group (F = 3.4, P = 0.055).

Conclusions:

Nurses have essential roles in cancer pain. A pain management education program can improve nurses' knowledge and attitude toward cancer-related pain.
