Review
Cancer pain requires careful comprehensive patient evaluation and an appropriate and personalized clinical approach by a trained multidisciplinary team. The proper assessment of breakthrough cancer pain (BTcP) is part of an all-inclusive multidimensional evaluation of the patient. The aim of this narrative review is to explore the relationship between high-rate BTcP, which strongly impacts health- related quality of life and tumour characteristics, in the face of novel approaches that should provide guidance for future clinical practice. The presentation of short, emblematic clinical reports also promotes knowledge of BTcP, which, despite the availability of numerous therapeutic approaches, remains underdiagnosed and undertreated. This article is part of the Special Issue: https://www.drugsincontext.com/special_issues/management-of-breakthrough-cancer-pain.

Cancer pain intensity (PI) fluctuates, but the relationship between pain flares and background pain with respect to pain management is not settled. We studied how flare and background PIs corresponded with treatment results for background cancer pain. Patients admitted to an acute palliative care unit with average and/or worst PI ≥ 1 on the 11-point numeric rating scale were included. Average and worst PI at admission and average PI at discharge were collected. We examined how the difference and ratio between worst and average PI and average PI at admission, were associated with average PI development during hospitalization. Positive differences between worst and average PI at admission were defined as pain flares. Ninety out of 131 patients had pain flares. The reduction in average PI for patients with flares was 0.9 and for those without, 1.9 ( = 0.02). Patients with large worst minus average PI differences reported the least improvement, as did those with large worst/average PI ratios. Patients with pain flares and average PI ≤ 4 at admission had unchanged average PI during hospitalization, while those with pain flares and average PI > 4 experienced pain reduction (2.1, < 0.001). Large pain flares, in absolute values and compared to background PI, were associated with inferior pain relief.

Boney metastasis may lead to terrible suffering from debilitating pain. The most likely malignancies that spread to bone are prostate, breast, and lung. Painful osseous metastases are typically associated with multiple episodes of breakthrough pain which may occur with activities of daily living, weight bearing, lifting, coughing, and sneezing. Almost half of these breakthrough pain episodes are rapid in onset and short in duration and 44% of episodes are unpredictable. Treatment strategies include: analgesic approaches with "triple opioid therapy", bisphosphonates, chemotherapeutic agents, hormonal therapy, interventional and surgical approaches, steroids, radiation (external beam radiation, radiopharmaceuticals), ablative techniques (radiofrequency ablation, cryoablation), and intrathecal analgesics.

Review
Breakthrough cancer pain (BTcP) is a complex and variegate phenomenon that may change its presentation during the course of patients' disease in the same individual. An appropriate assessment is fundamental for depicting the pattern of BTcP. This information is determinant for a personalized 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. The most controversial point regards the opioid dose to be used. The presence of opioid tolerance suggests to use a dose proportional to the dose used for background analgesia. In contrast, regulatory studies have suggested to use the minimal available dose to be titrated until the effective dose. Further large studies should definitely settle this never ended question.

Recent data indicate that there are large disparities in the use of opioid analgesics to control breakthrough cancer pain (BTcP) in Europe and worldwide. While it is clear that affordability is a key factor, it is certainly not the only one, and other factors, such as cultural differences and overall awareness, are undoubtedly responsible. More work remains to be done to overcome barriers in the use of these medications when warranted. When prescribing a medication for BTcP, it must be considered that its time profile is different from chronic persistent pain. The best control of background pain can best be achieved with a low dose of an extended opioid, and managing BTcP with a rapid-onset opioid, providing a good combination of overall pain control and lower opioid exposure. Notwithstanding their efficacy, greater attention needs to be paid to inappropriate use of opioids. It is important to evaluate patients for potential opioid misuse, including assessment of risk factors, and aberrant drug-taking behaviours must be investigated. In our institution, several measures have been adopted in this patient population in order to prevent aberrant opioid-induced behaviours. The adoption of some or all of these principles, depending on the individual patient and treatment setting, can undoubtedly help to reduce the risk of developing an aberrant behaviour related to opioid use as rescue medication for BTcP.

Review
The assessment and treatment of breakthrough cancer pain (BTcP) remain a major challenge in medicine due to its high impact on several aspects of health-related quality of life. BTcP should be carefully monitored in all cancer care settings by a multidisciplinary team to provide an appropriate and personalized clinical approach. The aim of this paper is to provide healthcare professionals involved in cancer pain management with a review of the relevant literature on the relationship between background cancer pain and BTcP which, by definition, occurs despite adequately controlled background cancer pain. The clinical cases presented contribute to a better understanding of this issue and underline its impact in daily clinical practice.

Review
Breakthrough cancer pain (BTcP) is a common condition in oncological patients. However, its management is still suboptimal. Improved knowledge of BTcP and its management in clinical practice may have immediate importance for all physicians involved in the supportive care of cancer patients. This review critically discusses the most important concepts for the correct diagnosis of BTcP and presents some intriguing cases of the management of this condition in clinical practice. Overall, the most appropriate therapeutic choice appears to be a rapid-onset opioid (ROO), and in particular, the nasal route of administration is the quickest and most convenient mode of administration for the management of BTcP, especially when the patient needs rapid resolution of pain. To this end, intranasal fentanyl spray may have a particular relevance in clinical practice. Future research should focus on accepted definitions of BTcP to investigate the optimal management of this highly heterogeneous pain condition. Therapeutic decision-making of patients, clinicians, and payers will likely be driven from results of well-designed clinical trials of ROOs.

Review
Multimodal analgesia (MMA) involves the use of additive or synergistic combinations of analgesics to achieve clinically required analgesia while minimizing significant side effects associated with higher dose of a single equianalgesic medication such as an opioid analgesic. MMA generally involves optimizing non-opioid pharmacologic and non-pharmacologic interventions and reserving opioid use to treat breakthrough pain. Patients receiving medications via MMA protocols are likely to have lower opioid consumption compared to those managed using primarily IV opioid patient-controlled analgesia. MMA pain management strategies have become important components of enhanced recovery after surgery (ERAS) protocols in an effort to optimize care by standardizing analgesic medications in the perioperative setting while minimizing adverse effects and improving quality and patient outcomes. Successful implementation of a MMA requires the input and cooperation of all of the stakeholders including the caregivers as well as the patients. Health system benefits can also be realized from the implementation of an effective MMA, as fewer opioid related side effects can improve patient recovery and lead to faster discharge and improved utilization of resources.

BACKGROUND
Methadone is commonly considered an alternative opioid treatment for refractory cancer pain. This study aims to investigate the efficacy, safety, and cost of methadone in the treatment of refractory cancer pain.
METHODS
A retrospective study was conducted in patients who used methadone for refractory cancer pain from April 2016 to December 2020 at a cancer specialized hospital. Pain control, evaluated via pain score and breakthrough pain frequency, and adverse events of methadone were compared with analgesic regimens prior to methadone administration. The factors potentially affecting the switching outcome were analyzed via multivariate analysis. Moreover, the cost of pain control was estimated.
RESULTS
Ninety patients received methadone for poor pain control (74.4%), intolerable adverse events (10.0%), or both (15.6%) after prior opioid treatments. Sixty-four patients (71.1%) were successfully switched to methadone with median pain score significantly decreased from 4.0 to 2.0 (p < 0.001) and median daily frequency of breakthrough pain from 3.0 to 0.0 (p < 0.001) at a maintained median conversion ratio of 6.3 [interquartile range (IQR): 4.0-10.0] to prior opioid treatment. Similar adverse event profiles of constipation, nausea, vomiting, and dizziness were observed between methadone and prior opioid regimens. The median daily cost of analgesic regimens was significantly reduced from $19.5 (IQR: 12.3-46.2) to $10.8 (IQR: 7.1-18.7) (p < 0.01) after switching to methadone. The 3-day switch method significantly improved the rate of successful switching compared with the stop and go method (odds ratio = 3.37, 95% CI: 1.30-8.76, p = 0.013).
CONCLUSION
Methadone is an effective, safe, and cost-saving treatment for patients with refractory cancer pain.
