The use of opioids for cancer-related pain is essential but poses significant challenges due to the risk of misuse and the development of opioid use disorder (OUD). This review takes a multidisciplinary perspective based on the current scientific literature to analyze the pharmacological mechanisms, classification, and therapeutic roles of opioids in oncology. Key risk factors for opioid misuse—including psychiatric comorbidities, prior substance use, and insufficient clinical monitoring—are discussed in conjunction with validated tools for pain assessment and international guidelines. The review emphasizes the importance of integrating toxicological, pharmacological, physiological, and public health perspectives to promote rational opioid use. Pharmacogenetic variability is explored as a determinant of treatment response and addiction risk, underscoring the value of personalized medicine. Evidence-based strategies such as early screening, psychosocial interventions, and the use of buprenorphine-naloxone are presented as effective measures for managing OUD in cancer patients. Ultimately, this work advocates for safe, patient-centered opioid prescribing practices that ensure effective pain relief without compromising safety or quality of life. Full article

Background/Objectives: Biofeedback interventions are increasingly utilized in pediatric and adult care, with evidence in treating specific medical conditions and specific symptoms. However, evidence supporting their efficacy among children and adolescents and young adults (AYAs, aged 15–39) with cancer is limited. The aims of this systematic review are to present, assess, and synthesize the existing research on biofeedback in pediatric and AYA oncology, identify gaps in biofeedback research within this population, and provide recommendations for future research and clinical implications. Methods: A systematic search for articles was conducted using six bibliographic databases—PubMed/MEDLINE (NLM), EMBASE (Elsevier), CINAHL (EBSCO), SPORTDiscus (EBSCO), PsycINFO (OVID), and PEDro (NeuRA)—with an update on 5/7/2025. Included were studies involving pediatric/AYA oncology participants (0–39 years old) and those receiving at least one biofeedback modality. The methodological quality and risk of bias among included articles were assessed using the Cochrane Risk of Bias (ROB) Tool (modified version for non-randomized studies). A narrative synthesis of included studies examined the type of cancer studied, type of biofeedback used, study designs and methodological quality, and key outcomes evaluated. Results: While the literature suggests that biofeedback may offer beneficial outcomes for managing various pediatric/AYA oncology-related symptoms, such as pain, anxiety, and fatigue, only 8 studies out of 1013 screened (<1%) met inclusion criteria. Limitations included low study quality (small sample sizes, lack of control groups, and methodological inconsistencies). Conclusions: While biofeedback shows promise as a feasible and effective intervention, there is a call to action for well-designed, methodologically rigorous studies to substantiate its effectiveness and inform evidence-based practice specifically for pediatric/AYA oncology patients and clinicians.

Animal venoms are complex biochemical secretions rich in highly potent and selective bioactive molecules, including peptides, enzymes, and small organic compounds. Once associated primarily with toxicity, these venoms are now recognized as a promising source of therapeutic agents for a wide range of medical conditions. This review provides a comprehensive analysis of the pharmacological potential of venom-derived compounds, highlighting their mechanisms of action, such as ion channel modulation, receptor targeting, and enzyme inhibition. Successful venom-derived drugs like captopril and ziconotide exemplify the translational potential of this biological arsenal. We discuss therapeutic applications in cardiovascular diseases, chronic pain, cancer, thrombosis, and infectious diseases, as well as emerging peptide candidates in clinical development. Technological advancements in omics, structural biology, and synthetic peptide engineering have significantly enhanced the discovery and optimization of venom-based therapeutics. Despite challenges related to stability, immunogenicity, and ecological sustainability, the integration of AI-driven drug discovery and personalized medicine is expected to accelerate progress in this field. By synthesizing current findings and future directions, this review underscores the transformative potential of animal venoms in modern pharmacotherapy and drug development. We also discuss current therapeutic limitations and how venom-derived compounds may address unmet needs in specific disorders. Full article

Introduction: Breast cancer therapy is a common cause of lymphedema. The accumulation of protein-rich fluid in the affected extremity leads to a progressive path—swelling, inflammation, and fibrosis—namely, irreversible changes. Methods: A scientific literature analysis was performed on PubMed/Medline, Scopus, Web of Science (WoS), the Cochrane Central Register of Controlled Trials (CENTRAL), and the Physiotherapy Evidence Database (PEDro) from inception until 30 June 2024. Results: Breast cancer-related lymphedema (BCRL) is indeed an important healthcare burden both due to the significant patient-related outcomes and the overall social impact of this condition. Even though lymphedema is not life-threatening, the literature underlined harmful consequences in terms of pain, infections, distress, and functional impairment with a subsequent and relevant decrease in quality of life. Currently, since there is no cure, the therapeutic approach to BCRL aims to slow disease progression and prevent related complications. A comprehensive overview of postmastectomy lymphedema is offered. First, the pathophysiology and risk factors associated with BCRL were detailed; then, diagnosis modalities were depicted highlighting the importance of early detection. According to non-negligible changes in patients’ everyday lives, novel criteria for patients’ functioning assessment are reported. Regarding the treatment modalities, a wide array of conservative and surgical methods both physiologic and ablative were analyzed with their own outcomes and downsides. Conclusions: Combined strategies and multidisciplinary protocols for BCRL, including specialized management by reconstructive surgeons and physiatrists, along with healthy lifestyle programs and personalized nutritional counseling, should be compulsory to address patients’ demands and optimize the treatment of this harmful and non-curable condition. The Lymphedema-specific ICF Core Sets should be included more often in the overall outcome evaluation with the aim of obtaining a comprehensive appraisal of the treatment strategies that take into account the patient’s subjective score.

Background/Objectives: This study evaluates the effects of a personalized exercise program on symptoms (pain, fatigue, sleep, cognitive function, physical function), resilience, and health-related quality of life (HRQOL) and compares the effectiveness of in-person versus telehealth delivery. Methods: A secondary data analysis was conducted on two 12-week randomized control pilot studies for solid tumor cancer survivors. One study involved in-person home visits with telephone follow-ups. The second utilized weekly exercise recommendations via a smartphone app. Both studies had control participants who received the standard care. Symptoms, resilience, and HRQOL were measured at baseline and after 12 weeks. Paired t-tests were conducted for intervention effects and ANCOVA for group differences, adjusting for age and education. Results: The analysis included 75 program completers: 15 in-person (iHBE), 38 telehealth (TEHE), and 22 who received standard care. Those receiving exercise interventions reported improvements in physical (t = 3.0, p < 0.01) and mental fatigability (t = 3.1, p < 0.01) at program completion compared to baseline. Comparing the mean changes between participants receiving exercise interventions in-person and via telehealth, there were no significant differences between the two delivery methods except perceived visuo-perceptual cognitive difficulty (F = 3.55, p = 0.027), where telehealth showed a slight advantage. Conclusions: The study provides initial evidence of the effectiveness of a telehealth personalized exercise on fatigability and cognitive difficulty, suggesting it is a potential viable alternative to in-person intervention. Further research with a larger cohort is essential to ascertain the effects of these interventional modalities on cancer-related health outcomes. Full article

Background/Objectives: Childhood cancer, although relatively rare, has a profound impact on the quality of life of affected children and their families. Technological advances have facilitated the development of mobile applications (apps) aimed at enhancing symptom monitoring and improving communication with healthcare teams. This systematic review aimed to analyse the effect of mobile applications on the health of children with cancer, with a specific focus on health-related quality of life (HRQoL). Methods: A systematic review was conducted in accordance with PRISMA 2020 guidelines. Searches were performed in PubMed (Medline), CINAHL, Cochrane and Scopus databases using MeSH terms such as Smartphone, Mobile Applications, Child Health, Neoplasms, and Digital Health, with no date restrictions, and including studies published in English, Spanish or Portuguese. We included original research studies that examined the use of mobile apps in paediatric oncology patients. The search was completed in January 2025. Results: Of the 324 records initially identified, 14 studies (mainly pilot studies, early-phase clinical trials, and observational designs) met the inclusion criteria. Interventions commonly focused on symptom tracking (pain, nausea, fatigue), promoting treatment adherence, and delivering educational content. Several studies reported high user acceptance and a potential positive impact on HRQoL, particularly when gamification strategies were incorporated to sustain children’s engagement. Conclusions: Despite the preliminary nature and small sample sizes of most studies, mobile applications appear to be effective in supporting symptom management, communication, and health education in paediatric oncology. Their use may contribute to improvements in HRQoL. Further high-quality research involving younger children and diverse socio-cultural contexts is required to confirm their effectiveness.

Background: Cachexia worsens prognosis, quality of life and chemotherapy treatment compliance of patients with lung cancer. Chemotherapy-induced cachexia has also been implicated in lowered mortality. This study aimed to evaluate the frequency of cachexia-related measures and symptoms as outcomes in lung cancer chemotherapy trial protocols and to examine how key trial characteristics influence them. Method: We conducted a cross-sectional data analysis of randomised controlled chemotherapy trials of lung cancer registered in four public trial registries between 2012 and 2023. Trial outcome measures included overall survival, treatment toxicity/side effects and cachexia-related indicators such as physical activity, weight/body mass index (BMI), dietary limitations, caloric intake and lean muscle mass. Symptom-related outcomes, including appetite loss, diarrhoea, pain, fatigue/insomnia, constipation, nausea, vomiting, dysphagia, dyspnoea and oral mucositis, were also extracted. Additionally, the number and type of performance status and assessment tool were recorded. Data were summarised descriptively. Chi-square tests were used to examine associations between trial outcomes and characteristics including cancer type, trial location, lead investigator/funding source, assessment tools and trial commencement year. A p < 0.05 was considered statistically significance. Results: Of the 335 trial protocols (non-small cell (87.2%) and small cell (12.8%)), most were from Europe (50.4%). The trial lead investigator was from industry (56.7%) followed by academia (25.1%). Allied health professional involvement was minimal (0.6%). Trial protocols mostly recorded overall survival (96.4%) and toxicity (83.9%). However, physical activity, weight/BMI, dysphagia, dyspnoea and oral mucositis were recorded in <30%, with dietary limitations, caloric intake and lean muscle mass recorded in <3% of the trials. Measures and symptoms were not associated with cancer type. Trial location was associated with the measures toxicity, physical activity and caloric intake and all symptoms. Lead investigator was associated with the measures toxicity and weight/BMI and all symptoms except for dyspnoea. Performance status and assessment tools were mentioned in 93.4% and 41.8% of the trials, respectively, with significant associations between assessment tools and outcomes, except for weight/BMI, dietary limitations, lean muscle mass, dysphagia and oral mucositis. There was a significant trend with trial commencement year for the measures physical activity (p = 0.002) and weight/BMI (p = 0.000) and all symptoms, except for appetite loss (p = 0.115) and pain (p = 0.433). Conclusions: While the reporting of measures and outcomes was generally higher compared to gastrointestinal chemotherapy cancer trials, it still faced significant under-reporting. Assessment tools should include cachexia-specific symptoms to accurately assess the quality of life in patients with lung cancer undergoing chemotherapy clinical trials. Full article

Magnesium (Mg²⁺) has gained oncologists’ attention due to its wide range of biological functions and frequent use as a complementary or integrative agent. This review outlines Mg’s actions, its complex role in carcinogenesis and tumor risk, and clinical issues. Mg²⁺ is essential in numerous biochemical processes, including adenosine triphosphate production, cellular signal transduction, DNA, RNA and protein synthesis, and bone formation. Pertinent full-text articles were thoroughly examined, and the most relevant ones were selected for inclusion in this review. There is conflicting scientific evidence about the relationship between Mg²⁺ changes and cancer risk, apart from colorectal cancer. Chronic Mg²⁺ deficiency leads to immune dysfunctions and enhanced baseline inflammation associated with oxidative stress related to various age-associated morbidities and cancer. On the other hand, Mg²⁺ deficiency is associated with drug or chemotherapy-related hypomagnesemia, postoperative pain, cachexia, opioid-induced constipation, normal tissue protection from radiation damage, and prevention of nephrotoxicity. A balanced diet usually provides sufficient Mg²⁺, but supplementation may be necessary in some clinical settings. Full article

(1) Background: Quality of life (QoL) assessment is a crucial aspect for patients diagnosed with cancer. Over the years, different tools have been developed to measure QoL, both generic and pathology specific, but the inclusion of quality of life among other indicators of efficacy in randomized controlled trials (RCTs) remains a controversial issue. In this review, we aim to review the frequency and modality of QoL assessment in RCTs, enrolling patients diagnosed with mesenchymal tumors. (2) Methods: An electronic literature search of bone and soft tissue sarcoma and GIST-related RCTs published between January 2000 and December 2023 was performed by two independent reviewers using PubMed. English-language phase II and III clinical trials enrolling at least more than 15 patients were included, regardless of the disease stage. Studies involving patients under the age of 18 years or for which the full text was not available were excluded. For each study, data regarding the journal and year of publication, the study design, the primary objective, and the evaluation of quality of life as an endpoint with any type of patient-reported outcomes used were extracted. (3) Results: Among the 742 publications screened, 171 resulted eligible. QoL assessment was listed among the endpoints in 35 trials and QoL results were reported in 29 primary publications. In these trials, 16 included patients with soft tissue sarcomas, 8 Kaposi sarcomas, 6 GIST, and 3 desmoid tumors. Among all the trials included, 10.4% on an adjuvant/neoadjuvant setting and 24.4% on a metastatic setting included QoL as an endpoint. The proportion of trials, including QoL, was variable over time, as follows: 16.9% of trials in 2000–2014 vs. 23.4% in 2015–2023. In 35 trials, including QoL endpoints, 27 had a superiority design and 25 reported a positive result. In the majority of trials (80%), the tools for QoL assessment were generic and those mostly used were the EORTC QLQ-C30, the EQ-5D questionnaire, and the modified Brief Pain Inventory–Short Form. (4) Conclusions: Quality of life has not been assessed or published in many phase II and III trials, despite an improvement over time. QoL evaluation in RCTs should be considered even more carefully in patients with rare tumors, where the low number of patients who can be enrolled makes it difficult to draw statistically significant conclusions on the effectiveness of treatments.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy. CIPN can lead to a dose reduction and/or the interruption of chemotherapy, limiting its effectiveness, while chronic CIPN decreases patients’ quality of life. Improvements in cancer treatment and patients’ survival have increased the number of patients living with CIPN. The only evidence-based treatment for CIPN-related pain, duloxetine, provides only modest clinical benefit, and there is no effective clinical management option for numbness and tingling. Several experimental studies and clinical reports suggest that adjuvant ozone treatment may be beneficial in managing CIPN. Methods: This narrative review aims to provide an overview of current knowledge regarding CIPN and ozone therapy. Specifically, it summarizes experimental studies (18) and clinical reports (27) published between 1995 and 2025 that offer preliminary evidence supporting the potential role of ozone treatment in managing CIPN, highlighting the need for ongoing randomized clinical trials to establish its efficacy. Additionally, this review highlights existing gaps in the literature and proposes directions for future research. Results: The hypothesized mechanisms of action and experimental findings suggest that ozone therapy may be a valuable intervention for CIPN, a concept supported by preliminary clinical observations. Conclusions: Clinically relevant approaches for established CIPN are currently unavailable. While preliminary data suggest a potential role of ozone therapy, clinical evidence remains limited. Further high-quality randomized controlled trials are needed to confirm its efficacy and safety in this context; several trials are currently ongoing. Full article

Gene therapy has emerged as a promising therapeutic approach across various oral diseases. This review examines current applications and future prospects of gene therapy in dentistry, focusing on five key areas: oral cancer, cancer-related pain, xerostomia (dry mouth), dental caries, and periodontal disease. Recent advances in viral and non-viral vectors have enabled more efficient gene delivery systems, with particular success in cancer pain management through µ-opioid receptor gene transfer and xerostomia treatment using aquaporin-1 gene therapy. For periodontal applications, gene therapy strategies include both immunomodulation and tissue regeneration approaches using growth factors like platelet-derived growth factor and bone morphogenetic proteins. While significant progress has been made, particularly in treating radiation-induced xerostomia and oral cancer pain, challenges remain in vector optimization and delivery methods. Clinical trials, predominantly in Phase I, indicate both the potential and current limitations of gene therapy in oral healthcare. This review synthesizes current evidence and outlines future directions for gene therapy applications in oral medicine and dentistry. Full article

Background: Endocrine therapies are accompanied by side effects that significantly impact the quality of life (QoL) of women with breast cancer. Adequate diet is important for fulfilling nutritional requirements, preserving health, and supporting therapy in this vulnerable population. Methods: This preliminary study evaluated the QoL of life and dietary intake in 185 women with breast cancer on two therapies, aromatase inhibitors (AIs) and tamoxifen, using the Functional Assessment of Cancer Therapy—Endocrine Symptoms (FACT-ES), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and Breast Cancer Specific Questionnaire (QLQ-BR23) and a 24 h dietary recall. A total of 185 women were included in the study and fulfilled the FACT-ES, of whom 73 fulfilled other two questionnaires and a 24 h recall. Results: No significant differences were found in the overall QoL between groups. Joint pain (95.3%) and reduced libido (84.7%) were most common with AIs, while tamoxifen users more frequently reported weight gain and irritability (93.0%, each), and vasomotor and gynecological symptoms. Macronutrient intake was similar, though AIs users consumed more energy-dense (p ≤ 0.001) and sugary foods (p = 0.034), while tamoxifen users had higher omega-6 PUFA intake. Both groups exhibited suboptimal intake of vitamin D, calcium, and selenium, and a higher phosphorus consumption relative to recommended daily values. Conclusions: Preliminary findings showed that QoL and dietary intake were comparable between patients with BC on AIs and tamoxifen treatment. Endocrine-related symptoms were more prevalent among tamoxifen users, whereas joint pain was most common in AIs users. Nutritional interventions may be warranted in both groups to ensure adequate intake of essential micronutrients in accordance with recommended dietary guidelines. Full article

Background and Aim: Neuropathic pain leads to a significant deterioration in health-related quality of life (HRQOL). Treating neuromusculoskeletal pain is especially important to prevent and improve physical frailty and the locomotive syndrome. Varied pharmacotherapies could be applicable for neuropathic pain patients, but evidence has been limited for a wide range of neuropathic pain conditions with different etiologies. The aim of this review was to highlight mirogabalin, a novel calcium channel α2δ ligand which was first approved in Japan, and which is effective for various types of neuropathic pain diseases. Methods: We conducted a narrative review of the recent evidence that mirogabalin has significant analgesic potency for varied types of neuropathic pain conditions. Futher, this review highlighted specific advantages over other calcium channel ligands. Results: Analgesic potency of mirogabalin could cover peripheral neuropathic pain conditions including post-herpetic neuralgia, diabetic peripheral neuropathy, cauda equina syndrome caused by lumbar spinal stenosis, radiculopathy caused by cervical spondylosis, and also central neuropathic pain conditions like spinal cord injury. Mirogabalin consistently demonstrated daytime sleepiness and dizziness as adverse effects, but most of these were mild. Conclusions: Mirogabalin is recommended as the first-line drug against most molecular mechanisms that cause neuropathic pain regardless of whether they have a peripheral or central origin. Mirogabalin demonstrates relatively less daytime sleepiness, making it age-friendly in the current global situation where population aging is accelerated. Considering the epidemic of ‘opiophobia’ in Japan and other countries, pharmacotherapy using mirogabalin could treat neuropathic pain associated with cancer and its treatment (e.g., chemotherapy-induced peripheral neuropathy), as well as non-cancer etiologies worldwide.

Background and Objectives: Rectal cancer is a major cause of morbidity and mortality worldwide, and although current therapeutic protocols have improved survival, treatment-related toxicities may significantly affect patients’ daily functioning and emotional well-being. This study aimed to prospectively assess the impact of radiotherapy with concurrent capecitabine on functional and symptomatic outcomes in patients with rectal cancer, with a particular focus on the presence of a stoma and treatment strategy. Materials and Methods: From 165 patients initially assessed, 64 were included in this study after applying eligibility criteria. All received pelvic radiotherapy (50.4 Gy in 28 fractions); 62.5% also received CAPOX chemotherapy. The quality of life was assessed using EORTC QLQ-C30 and QLQ-CR29 questionnaires administered at three time points: before treatment, mid-treatment (day 15), and post-treatment. Results: A statistically significant deterioration was observed in physical, emotional, social, and role functioning over the course of treatment, along with an increase in symptom scores for fatigue, pain, gastrointestinal, and urinary complaints. The presence of a stoma was significantly associated with worse gastrointestinal symptoms and emotional functioning. No significant differences were noted between patients with or without chemotherapy. Despite symptom worsening, global quality-of-life scores remained relatively stable. Conclusions: These findings highlight the complex interplay between treatment toxicity and patient adaptation. The presence of a stoma and other clinical or demographic factors significantly influence patients’ experience during therapy. Integrating routine assessment of functional and symptomatic burden into clinical practice could support individualized interventions aimed at maintaining daily functioning and psychological resilience during treatment.

Background: Breast cancer survivors (BCS) experience long-term adverse effects, with breast cancer-related lymphedema (BCRL) being one of the most common complications. Exercise is suggested as a safe strategy to improve functionality in BCS with or at risk of developing BCRL. However, the effects of concurrent training in these patients are poorly understood. The aim of the study was to analyze the effects of a 12-week supervised concurrent training program and a 12-week follow-up period without training on molecular, functional, and clinical outcomes in BCS. Methods: A single-arm study was conducted in 11 BCS with or at risk of BCRL to analyze the effects of a 12-week concurrent training and a 12-week follow-up period on molecular (92 inflammation-related proteins), functional (upper- and lower-body strength, handgrip strength, and cardiorespiratory fitness), and clinical (body mass index, arm volume, subcutaneous and muscle thickness, range of motion, physical activity levels and heart rate variability, pain, and quality of life [QoL]) outcomes. Results: The 12-week concurrent training program significantly improved upper-body muscle strength, handgrip strength, pain, emotional well-being, and total QoL. In addition, after the 12-week follow-up period, the increase in row strength was maintained, and a significant decrease in various inflammation-related proteins was observed. Conclusions: A 12-week concurrent training program improved strength, pain, and QoL in BCS without increasing inflammation. After the follow-up period, inflammation-related protein levels decreased, and row strength gains were maintained, supporting the potential effects of concurrent training. Further larger and controlled studies are needed to confirm the results. Full article
