Fentanyl in cancer pain management: avoiding hasty judgments and discerning its potential benefits.

Cancer pain is an important challenge in treatment and requires a rapid onset of action for its control. In particular, breakthrough cancer pain (BTcP) should be adequately controlled with a stable dose of a short-acting oral opioid. Fentanyl is a synthetic, highly selective opioid with many advantageous chemical properties, including high lipophilicity and distinct pharmacokinetic properties. It is recommended for pain management in a variety of settings, including acute pain, chronic pain and BTcP. To date, its variously designed formulations allow non-invasive administration; amongst others, sublingual fentanyl has proven useful in the management of BTcP and in improving the quality of life of patients with cancer. This review provides an update on the management of BTcP with fentanyl, with consideration of safety, as it remains an important tool in the treatment of cancer pain.

Breakthrough Cancer Pain

Health Organization defined breakthrough pain as a temporary increase in pain from pre-existing underlying pain with moderate to severe pain intensity. Cancer patients with chronic pain experience breakthrough cancer pain during their illness. Breakthrough cancer pain caused high morbidity in patients that disrupts the quality of life of patients and their families. Until now, the causes of breakthrough cancer pain are multifactorial and subjective, therefore the assessment and management are very complex. This article aimed to provide a comprehensive and focused review from the definition to the management of breakthrough cancer pain. Keywords: Breakthrough cancer pain, chronic pain, moderate-severe intensity.

Predicting tolerability of high-dose fentanyl buccal tablets in cancer patients.

Fentanyl buccal tablets (FBTs) are a rapid-onset opioid indicated for breakthrough cancer pain (BTcP) and FBT titration is needed to optimize BTcP management. We aimed to predict which patients could tolerate a high dose of FBT (400 μg or more at a time). A retrospective analysis was performed to assess the final FBT dose. The final FBT doses were compared according to the clinical features. The prediction accuracy of patients tolerant of 400 μg or higher FBT was compared using the area under the receiver operating characteristic (ROC) curves. A risk scoring model based on the odds ratio (OR) was developed from the final multivariable model, and patients were assigned into two groups: low tolerance (0-1 point) and high tolerance (2-3 points). Among 131 patients, the most frequently effective dose of FBT was 200 μg (54%), followed by 100 μg (30%). The median value of morphine equivalent daily doses (MEDD) was 60 mg/day, and the most common daily use was 3-4 times/day. In multivariable analysis, male sex, younger age, and use of FBTs three or more times per day were independently associated with high-dose FBT. According to the risk scoring model, the patients with a final FBT of 400 μg or higher were significantly more in the high tolerance group (17%) compared to the low tolerance group (3%; p = 0.023). According to the dose relationship between the final FBT dose and the clinical features, three factors (sex, age, daily use of FBT) were independently associated with the final dose of FBT. Our risk score model could help predict tolerance to high-dose FBT and guide the titration plan for BTcP.

Rapid-Onset Opioids for Management of Breakthrough Cancer Pain: Considerations for Daily Practice.

Background and ObjectiveRapid-onset opioids (ROOs) are effective treatments for breakthrough cancer pain (BTcP) given their rapid onset of action and relatively short duration of analgesia. The aim of this article is to describe specific considerations for the use of ROOs in daily practice, focusing on dose titration and treatment of specific populations.Type of ReviewWe conducted a narrative review on the use of ROOs for BTcP. We selected papers according to the following search terms: “breakthrough cancer pain” and “rapid onset opioids”.ResultsROOs may be considered as the most suitable drugs to treat BTcP and can be used “on-demand”. Several fentanyl formulations are available and have been associated with control of BTcP and with improvement in quality of life. Various titration schemes have been used to optimize ROO dosing; however, a dose-proportional scheme could be considered safe and effective in most patients. Specific formulations may be more suitable for specific patient subgroups; for example, patients with oral mucositis may prefer intranasal to oral formulations. Moreover, elderly patients or those without caregivers should be clearly educated on the use of these formulations. A key element in achieving successful treatment of BTcP is awareness of the barriers to pain management, including poor overall assessment, patient reluctance to take opioids or report pain, and physician reluctance to prescribe opioids.ConclusionA personalized approach is fundamental when prescribing a medication for BTcP, and careful attention should be given to drug choice and route of administration, and to the need for alternative therapeutic options.

Retrospective Observational Study on the Characteristics of Pain and Associated Factors of Breakthrough Pain in Advanced Cancer Patients.

Objective This study aimed to conduct a retrospective observational study to understand the status of characteristics of pain and identify potential variables influencing the clinical presentation of breakthrough cancer pain (BTP) in advanced cancer patients. Methods Advanced cancer patients over 18 years of age; diagnosed with cancer of any type and stage III or IV in the palliative care ward with available data were enrolled between 2018 and 2020. Demographic data and pain-related information were collected by using structured electronic extraction form from Hospital Information System (HIS). Patients who had well-controlled background pain with an intensity ≤4 on a 0–10 numerical scale for >12 hours/day, the presence of transient exacerbations of pain with moderate-severe intensity (≧5), and clearly distinguish from background pain were regarded to have suffered BTP. Spearman correlation was conducted to explore the relationship between pain score and demographics characteristics. Factors significant in univariate analysis were included in the multiple regression model to explore independent predictive factors associated with the BTP. Results Of 798 advanced cancer patients, the mean age was 56.7 (SD = 11.84) years. Lung cancer (29.95%) was the most common cancer, and pain (93%) was the most common symptom. More than half (n = 428, 53.6%) of the patients experienced BTP. The median number of BTP episodes was 4 (IQR = 2, 7, range: 1–42). The median intensity of BTP was 6 (IQR = 6, 7, range 5–10). Patients with severe background pain or BTP had longer hospital stay and more symptoms. Besides, more severe background pain was related to higher activity of daily living. Intramuscular injection of hydromorphone hydrochloride was the main medication for BTP onset. Younger age, background pain, anorexia, and constipation were independently associated with the presentation of BTP. BTP pain intensity was independently associated with bloating. Symptom numbers were an independent factor and positively associated with BTP episodes. Conclusions BTP resulted in poor prognosis, which has a variable presentation depending on interdependent relationships among different characteristics. Good controlling of background pain and assessment of pain-related symptoms are essential for BTP management. BTP should be managed individually, especially the invisible pain among aged patients. Furthermore, BTP-related education and training were still needed.

Clinical Practice Guidelines in the Management of Breakthrough Cancer Pain: A Systematic Review using the Appraisal of Guidelines for Research and Evaluation (AGREE II) Instrument

BackgroundSeveral clinical practice guidelines (CPGs), consensus statements, and recommendations currently exist for the diagnosis and management of breakthrough cancer pain (BTcP). These documents have considerable variability amongst them, and to date, their quality and methodologic rigor have not been appraised. AimWe aim to identify and perform a quality appraisal of CPGs for the diagnosis and management of BTcP using the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool. MethodsA comprehensive literature search was performed in MEDLINE (via PubMed), EMBASE, and SCOPUS databases up until January 1, 2021. Four reviewers independently evaluated each guideline using the AGREE II instrument. Scaled domain scores were generated and the threshold used for satisfactory quality was >60%. Additionally, intraclass correlation coefficients (ICC) were calculated to determine level of agreement between reviewers. ResultsEleven guidelines were selected for final evaluation based on inclusion/exclusion criteria. Only one guideline was classified of “average” quality while the rest were classified as “low” quality. The “Editorial Independence” (70.46 ± 35.7) and “Scope and Purpose” (64.78 ± 12.5) domains received the highest mean scores, while the “Applicability” (32.58 ± 13.5) and “Rigor of Development” (35.04 ± 9.0) domains received the lowest mean scores. ICC statistical analysis showed high magnitude of agreement between reviewers with a range of (0.790-0.988). ConclusionsReflecting upon our quality appraisal, it is evident that the quality and methodologic rigor of BTcP guidelines can be improved upon in the future. Our findings also elucidate the existing variability/discrepancies among guidelines in diagnostic criteria and management of BTcP.

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

BackgroundCancer 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.MethodsThis 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.ResultsFrom 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.ConclusionThis study proposes several key points to be considered in the pharmacological management of BTcP, useful to ensure patients’ satisfaction and optimal quality of life.

Strengths and Weaknesses of Cancer Pain Management in Italy: Findings from a Nationwide SIAARTI Survey.

Objectives: Despite guidelines, a large percentage of cancer patients continue to suffer from ineffectively treated pain. The authors undertook this survey to assess the strengths and weaknesses of cancer pain management in Italy. Design: This was a prospectively administered survey. Participants: The participants were anesthesiologists of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI). Intervention: A 58-item questionnaire covered the demographics and features of cancer pain management in the Italian context. Results: The authors received responses from 611 pain therapists of 279 centers. Only 22% of physicians are exclusively pain therapists. Seventy-five percent are specialists in anesthesiology, intensive care, and pain medicine. Most pain centers are hospital or university facilities (78%). The strengths of cancer pain management in Italy are the careful opioid prescriptions, the use of strategies for the treatment of neuropathic pain, patient/healthcare provider partnerships, and breakthrough cancer pain management. Weaknesses to be addressed include poor adherence to guidelines, inadequate attention toward the patient’s quality of life, insufficient use of minimally invasive techniques, lack of teamwork approaches, inappropriate timing of pain specialist engagement, and poor telemedicine use. Conclusions: Despite several strengths, further efforts are needed to improve the care of patients suffering from cancer pain in Italy.

Low-dose sublingual fentanyl improves quality of life in patients with breakthrough cancer pain in palliative care.

Aim: This subanalysis of the CAVIDIOPAL study evaluated the impact of individualized management of breakthrough cancer pain (BTcP) with fentanyl on the quality of life (QoL) of advanced cancer patients in Spanish palliative care units. Patients & methods: This was a prospective, observational, multicenter study. The European Organization for Research and Treatment of Cancer's QLQ-C30 questionnaire was used at baseline (V0) and visit 28 (V28). Results: Ninety-five patients were mainly treated with 67-133μg fentanyl, showing a notable reduction in intensity (visual analog scale: 8.0 [V0] to 4.6 [V28]), frequency and duration of BTcPepisodes shortly after the first 1-2weeks of treatment, with significantly improved QoL (global health status: 31.1 [V0] to 53.1 [V28]). Conclusion: Low-dose sublingual fentanyl effectively reduced BTcPin advanced cancer patients in palliative care units, significantly improving QoL. Clinical trial registration: NCT02840500 (ClinicalTrials.gov).

Cultural adaptation and psychometric validation of the Portuguese breakthrough pain assessment tool with cancer patients.

Breakthrough cancer pain (BTcP) is a transient exacerbation of pain that occurs over persistent, stable, and adequately controlled cancer background pain. It is prevalent and bears severe consequences to patients' quality-of-life. The effective management of BTcP depends on fast and reliable (re)assessment. The Breakthrough pain Assessment Tool (BAT) is one of the most concise and reliable self-report instruments adapted to clinical contexts so far, showing goodpsychometric qualities in the United Kingdom, the Netherlands, and South Korea. As to promote the effective management of BTcP in Portuguese-speaking communities this study, first aimed to culturally adapt and validate the Portuguese version of the BAT (BAT-Pt). Second, and most importantly, it sought to provide novel evidence on its criterion validity by investigating its association with measures of psychological distress, which has not been yet investigated. The BAT was translated into European Portuguese, using the back-translation method, and culturally adapted. Its psychometric properties (factor structure, internal consistency, construct and criterion validity) were analyzed in a cross-sectional multicenter study, with a sample of 65 cancer patients (49.2% women) recruited from eight hospitals in mainland Portugal (a priori power analysis determined a minimum sample of 50). Health professionals collected patients' clinical information, assessed their functional disability (ECOG Performance Status) and the adequacy of pain control. In addition to the Portuguese version of the BAT (BAT_Pt), patients completed the Portuguese versions of the Brief Pain Inventory, the Hospital Anxiety and Depression Scale, a Distress Thermometer and answered questions about the adequacy of pain control. The BAT-Pt was very well accepted by experts and patients. As hypothesized, a Principal Axis Factor Analysis revealed two underlying factors accounting for 55.2% of the variance: (1) Pain Severity and Impact of BTcP and (2) Duration of BTcP and Medication Inefficacy. Two items (on episode frequency and medication efficacy) were analyzed separately given their lower/cross loadings. The BAT-Pt showed good internal consistency overall (α=0.79) and for each sub-scale, namely, Pain Severity and Impact of BTcP (n=5 items; α=0.86) and Duration of BTcP and Medication Inefficacy (n=2 items; rsb=0.62). The BAT-Pt showed good convergent validity, being moderately to strongly associated with overall pain severity and interference (0.46<r<0.77, p<0.001). It also showed good concurrent validity by being associated not only with physical outcomes- such as functional disability (r=0.40, p<0.001) and patient- and physician-determined adequacy of BTcP control (|0.25<rpb<0.63|, p s <0.05)- but also, with distress (0.33<r<0.46, p s <0.001), anxiety (0.28<r<0.44, p s <0.05) and depression (r=0.47, p<0.001). The BAT-Pt is a reliable and valid measure of breakthrough pain in Portuguese cancer patients and it is strongly associated to physical and psychological outcomes. This study confirms and extends the psychometric validation of the BAT to a new cultural context, promoting its diffusion and use by researchers and clinicians in Portuguese-speaking communities. The BAT-Pt may be an invaluable tool for daily clinical practice by tapping multiple aspects of BTcP experiences that are associated to patients' physical and psychological outcomes.

Effect of a theory-driven educational intervention on the level of knowledge, attitudes, and assessment practices regarding breakthrough cancer pain (BTCP) management among medical nurses in Hong Kong.

To examine the effect of an educational intervention intended to improve medical nurses' adherence to breakthrough cancer pain (BTCP) assessment practices and their level of knowledge, attitudes and perceived assessment practices regarding BTCP management. Nurses working in a regional hospital were recruited to this quasi-experimental study. The intervention group received a 3-h educational workshop and one session of individual clinical instruction, whilst the control group did not receive any intervention. Chart audits were performed to examine adherence to BTCP assessment practices as the primary outcome. A self-developed questionnaire was used to measure nurses' knowledge, attitudes and perceived assessment practices regarding BTCP management as the secondary outcomes. The chi-square or Fisher's exact test was used to compare the rate of adherence to BTCP assessment practices between groups. A generalised estimating equation was used to compare changes in knowledge, attitudes, and perceived assessment practices between groups over time. One hundred and five nurses completed the study. The chart audits revealed a significantly higher rate of adherence to BTCP assessment practices in the intervention group after the intervention (p<.05). The intervention group exhibited significant positive changes in scores for knowledge (β=25.49, p<.001), attitude (β=0.98 to 2.81, p<.01), and their perceived assessment practices (β=1.33 to 3.14, p<.002) when compared with the control group. This theory-driven educational intervention significantly improved the medical nurses' adherence to BTCP assessment practices and their level of knowledge attitudes and perceived assessment practices regarding BTCP management.

Observational study of efficacy, safety, and tolerability of fentanyl in Korean cancer patients (OASIS)

Abstract Background: Sublingual fentanyl (Abstral) has been developed to provide rapid-onset analgesia in breakthrough cancer pain (BTcP). While the efficacy and safety of the fentanyl tablet have been already confirmed in clinical trials, there is no real-world evidence regarding the effectiveness and safety of this agent in the control of BTcP. Aims: To observe the effectiveness, safety and tolerability of Abstral for the alleviation of BTcP in Korean patients. Methods: The study is a non-interventional, observational study conducted in 13 hospitals in the Republic of Korea. Cancer patients (targeted number: 309), prescribed with Abstral due to the inability to control BTcP with other fentanyl products, are to be followed up for 12 weeks to collect the information about dose titration, pain status, quality of life, and adverse events. Conclusions: The list of inclusion and exclusion criteria is relatively short, which will likely make the study group more representative for the entire population of cancer patients with BTcP. All treatment-related decisions are left solely on the investigator's discretion, which will enable to analyze the treatment outcomes in various clinical scenarios, unlikely to be tested in a traditional clinical trial. These two features seem to be essential for the successful management of BTcP, a highly heterogeneous condition requiring an individualized approach. Further, the study includes patients who did not respond to other fentanyl formulations, and hence, it might explain whether switching from one immediate-release fentanyl to another is associated with a clinical benefit and/or specific risk. Trial registration: ClinicalTrials.gov with the identifier NCT03895762.

Impact of individualized management of breakthrough cancer pain on quality of life in advanced cancer patients: CAVIDIOPAL study

PurposeThe main aim of the study was to assess the impact of individualized management of breakthrough cancer pain (BTcP) on quality of life (QoL) of patients with advanced cancer in clinical practice.MethodsA prospective, observational, multicenter study was conducted in patients with advanced cancer that were assisted by palliative care units. QoL was assessed with the EORTC QLQ-C30 questionnaire at baseline (V0) and after 28 days (V28) of individualized BTcP therapy. Data on background pain, BTcP, comorbidities, and frailty were also recorded.ResultsNinety-three patients completed the study. Intensity, duration, and number of BTcP episodes were reduced (p < 0.001) at V28 with individualized therapy. Transmucosal fentanyl was used in 93.8% of patients, mainly by sublingual route. Fentanyl titration was initiated at low doses (78.3% of patients received doses of 67 μg, 100 μg, or 133 μg) according to physician evaluation. At V28, mean perception of global health status had increased from 31.1 to 53.1 (p < 0.001). All scales of EORTC QLQ-C30 significantly improved (p < 0.001) except physical functioning, diarrhea, and financial difficulties. Pain scale improved from 73.6 ± 22.6 to 35.7 ± 22.3 (p < 0.001). Moreover, 85.9% of patients reported pain improvement. Probability of no ≥ 25% improvement in QoL was significantly higher in patients ≥ 65 years old (OR 1.39; 95% CI 1.001–1.079) and patients hospitalized at baseline (OR 4.126; 95% CI 1.227–13.873).ConclusionIndividualized BTcP therapy improved QoL of patients with advanced cancer. Transmucosal fentanyl at low doses was the most used drug.Trial registrationThis study was registered at ClinicalTrials.gov database (NCT02840500) on July 19, 2016.

Understanding the Chameleonic Breakthrough Cancer Pain.

Breakthrough cancer pain (BTcP) is a variegated phenomenon, that often presents in different ways in each individual, and may change its presentation in the same individual during the course of disease. An appropriate assessment is fundamental for depicting the pattern of BTcP in individuals. This information is determinant for a personalised management of BTcP. The use of opioids as needed, is recommended for the management of BTcP. There are several options which should be chosen according to the individual pattern of BTcP. In general, a drug with a short onset and offset should be preferred. Although oral opioids may still have specific indications, fentanyl products have been found to be more rapid and effective, providing analgesia in 5-15 min. The most controversial point regards the opioid dose to be used. The presence of tolerance suggests using a dose that is proportional to the dose used for background analgesia. In contrast, regulatory studies have suggested using the minimal available dose to be titrated until the effective dose. Further large studies should definitely settle this never-ending question.

Breakthrough cancer pain: A delphi consensus study on expert recommendations for barriers that prevent the proper management of BTcP in Spain

Background: The management of Breakthrough cancer Pain (BTcP) remains unsatisfactory. Although many barriers to BTcP management have been identified, oncologists have not been able to overcome them. The aim of this study is to identify the barriers preventing proper BTcP management that Spanish medical oncologists have found, and to reach a consensus in order to draft the appropriate recommendations to overcome them. Methods: This study is based on two surveys conducted by oncologists. The first survey was designed to reach a consensus on the main barriers (related to patients, physicians and healthcare organizations) that stand in the way of BTcP control. The second survey (a Delphi questionnaire) was based on the barriers evaluated in the first survey, including recommendations assessed using the two-round Delphi methodology.

Breakthrough cancer pain treatment in Spain: physicians’ perception of current opioids utilization and prescription

Objectives: Multiple reasons for suboptimal treatment of breakthrough cancer pain (BTcP) have been reported in the literature. We aimed to ascertain the perception of physicians on the potential inappropriate use and prescription of rapid-onset opioids (ROOs) for breakthrough cancer pain (BTcP) and the causes thereof.Methods: Observational study based on an online survey addressed to doctors from different specialties (radiation oncology, medical oncology, anesthesia, palliative care and general practitioners) with experience in the management of BTcP in the Spanish public health setting.Results: A total of 114 eligible specialists mainly from radiation oncology (37.7%), medical oncology (24.6%) and pain units (18.4%) participated in the study. Most agreed on important aspects of BTcP management, such as their preference for ROOs or the need for early follow-up after treatment initiation. However, their answers revealed a lack of standardization of BTcP diagnosis. Half of respondents believed that their BTcP patients might misuse ROOs. Physicians polled believed that lack of training in pain management (71.9%) and inadequate BTcP diagnosis and evaluation (66.7%) were the greatest obstacles for prescribing opioids. Specialists also thought that they do not provide the necessary information to patients (51.8%) and caregivers (57.9%) to guarantee the correct use of these drugs.Conclusions: These results are of utmost importance as they highlight the need to increase physicians’ awareness of BTcP and its management and the need to improve communication with patients and their caregivers. Our findings also indicate the need for future research on the possible misuse of opioids in BTcP patients and its causes.

Patient Satisfaction with Fentanyl Pectin Nasal Spray in Breakthrough Cancer Pain Management During Radiotherapy for Head and Neck Cancer.

ObjectiveThe severity of breakthrough cancer pain (BTcP) impacts patients’ quality of life, increases the risk of anxiety and depression, lowers functional capacities, and may lead to poor compliance with cancer treatments. The aim of the current study was to assess, in a real-life setting, patient satisfaction with a fentanyl-pectin-nasal-spray (FPNS) for BTcP management in head and neck (H&N) cancer patients treated by radiotherapy.Materials and MethodsThis non-interventional, prospective study was conducted in 92 adult H&N-cancer patients undergoing radiotherapy and who started FPNS treatment for BTcP. Throughout the radiotherapy period, the patients completed self-diaries to assess their BTcP episodes, FPNS use, satisfaction on FPNS efficiency (primary outcome), tolerability and ease of use.ResultsPrior to FPNS treatment, 86% of the patients were experiencing ≤4 BTcP episodes/day. During the radiotherapy period, the BTcP episodes were treated with a median dose of 100µg of FPNS. Patients were “satisfied/very-satisfied” with the efficiency (73% of assessments), ease of use (87% of assessments) and tolerability (87% of assessments) of FPNS. In total, 27% of patients reported at least one adverse event related to FPNS and 4% of patients discontinued treatment due to adverse events. None of the adverse events were serious. Patient quality of life was maintained throughout the radiotherapy period.ConclusionThis study showed, in a real-life setting, that a clear majority of H&N cancer patients treated with FPNS for BTcP throughout radiotherapy expressed satisfaction with this analgesic treatment.

Careful Breakthrough Cancer Pain Treatment through Rapid-Onset Transmucosal Fentanyl Improves the Quality of Life in Cancer Patients: Results from the BEST Multicenter Study.

Objectives: To explore the effect of breakthrough cancer pain (BTcP) treatment on quality of sleep and other aspects of the health-related quality of life (HRQoL) in patients with cancer pain. Methods: In an observational, multicenter, cohort study, cancer patients from palliative care units, oncology departments, and pain clinics and affected by BTcP were included. Enrolled patients were assessed at the four visits: T0 (baseline), T7, T14, and T28. Stable chronic background pain (numeric rating scale, NRS ≤ 4) during the whole study period was mandatory. BTcP was treated through transmucosal fentanyl. Three questionnaires were used to measure the HRQoL: EORTC QLQ-C15-PAL, Pittsburgh Sleep Quality Index (PSQI), and the Edmonton Symptom Assessment System (ESAS). RESULTS: In 154 patients, the HRQoL showed a significant improvement for all physical and emotional characteristics in the EORTC QLQ-C15-PAL, except for nausea and vomiting (linear p-value = 0.1) and dyspnea (Linear p-value = 0.05). The ESAS and PSQI questionnaires confirmed these positive results (p < 0.0001 and p = 0.002, respectively). Conclusions: This prospective investigation by an Italian expert group, has confirmed that careful management of BTcP induces a paramount improvement on the HRQoL. Because in cancer patients there is a high prevalence of BTcP and this severe acute pain has deleterious consequences, this information can have an important clinical significance.

Breakthrough cancer pain: review and calls to action to improve its management.

In this paper, we review the current state of breakthrough cancer pain (BTcP) management. BTcP is a heterogeneous condition and a global problem for cancer patients. It is often managed suboptimally, which results in a negative outcome for patients, healthcare providers, and healthcare systems. Several barriers to the appropriate management of BTcP have been identified. These include, among others, an incomplete definition of BTcP, poor training of healthcare providers and patients alike, a lack of a multidisciplinary approach and the absence of specific protocols and tools. We provide some actions to help physicians and patients improve their approach to BTcP, including specific training, the design of easy-to-use tools for BTcP identification and assessment (such as checklists and pocket-sized cards), individualized treatment, and the use of multidisciplinary teams.
