Application and accuracy of the EAPC/IASP diagnostic algorithm for neuropathic cancer pain and quantitative sensory testing profile in patients with pain due to cancer.

Introduction: Better diagnosis and treatment of neuropathic cancer pain (NcP) remains an unmet clinical need. The EAPC/IASP algorithm was specifically designed for NcP diagnosis; yet, to date, there is no information on its application and accuracy. Objectives: Our aim was to determine the accuracy of the EAPC/IASP algorithm compared with the Neuropathic Special Interest Group grading system (gold standard) and to describe patients' sensory profile with quantitative sensory testing (QST). Methods: This is a cross-sectional observational study conducted in a palliative care and pain outpatient clinic. Patients with cancer pain intensity ≥3 (numerical rating scale 0-10) were eligible. The palliative care physician applied the EAPC/IASP algorithm as a grading system to diagnose probable or definite NcP, and an independent investigator applied the gold standard and performed the QST. Sensitivity and specificity of the EAPC/IASP algorithm were measured in comparison with the gold standard results. Kruskal-Wallis and unequal variance independent-samples t tests were used to compare the QST parameters in patients with and without NcP. Results: Ninety-eight patients were enrolled from August 2020 to March 2023. Sensitivity and specificity for the EAPC/IASP algorithm were 85% (95% CI 70.2-94.3) and 98.3% (95% CI 90.8-100), respectively. Patients with NcP in contrast to patients without NcP showed cold hypoesthesia (P = 0.0032), warm hypoesthesia (P = 0.0018), pressure hyperalgesia (P = 0.02), and the presence of allodynia (P = 0.0001). Conclusion: The results indicate a good performance of the EAPC/IASP algorithm in diagnosing NcP and the QST discriminated well between patients with and without NcP.

Finding predictors for successful opioid response in cancer patients: An analysis of data from four randomized controlled trials.

CONTEXT: There is no consensus on which "strong" (or step 3 WHO analgesic ladder) opioid to prescribe to a particular patient with cancer-related pain. A better understanding of opioid and patient characteristics on treatment response will contribute to a more personalized opioid treatment. OBJECTIVES: Assessment of potential predictors for successful opioid treatment response in patients with cancer pain. METHODS: An international partnership between four cancer pain research groups resulted in a combined individual-level database from four relevant randomized controlled trials (RCTs; n = 881). Together, these RCTs investigated the short-term (1 week) and medium-term (4 or 5 weeks) treatment responses for morphine, buprenorphine, methadone, oxycodone, and fentanyl. Candidate predictors for treatment response were sex, age, pain type, pain duration, depression, anxiety, Karnofsky performance score, opioid type, and use of anti-neuropathic drug. RESULTS: Opioid type and pain type were found statistically significant predictors of short-term treatment success. Sex, age, pain type, anxiety, and opioid type were statistically, significantly associated with medium-term treatment success. However, these models showed low discriminative power. CONCLUSION: Fentanyl and methadone, and mixed pain were found to be statistically significant predictors of treatment success in patients with cancer-related pain. With the predictors currently assessed our data did not allow for the creation of a clinical prediction model with good discriminative power. Additional - unrevealed - predictors are necessary to develop a future prediction model.

A real-world study on the prevalence and risk factors of medication related osteonecrosis of the jaw in cancer patients with bone metastases treated with Denosumab.

AIM: Assessing the incidence of Medication Related Osteonecrosis of the Jaw (MRONJ) in cancer patients with bone metastases receiving Denosumab (Dmab) and identifying potential risk factors. METHODS: A retrospective observational study on consecutive cancer patients with bone metastases, who received at least one dose of Dmab and one follow-up visit. MRONJ crude cumulative incidence (CCI) was estimated considering death without MRONJ as competing event. Multiple regression models were used to study the association between MRONJ incidence and potential risk factors: age, cancer diagnosis, previous bisphosphonates, dental treatments before starting Dmab, extraction or other dental treatment during Dmab, chemotherapy, hormone therapy, and antiangiogenic (AA) agents concurrent use. RESULTS: On 780 patients included (median follow-up 17 months), 54% and 18% had, respectively, breast and prostate cancer. The mean number of Dmab administration was 12. Fifty-six patients developed MRONJ with a 24- and a 48-month crude cumulative incidence of 5.7% (95% Cl: 4.2%-7.8%) and 9.8% (95% CI: 7.6%-12.7%), respectively. Higher MRONJ incidence was significantly associated with middle aged group (>56 and ≤73), both at univariate and multivariate analysis (p = 0.029 and 0.0106). Dental treatments (Hazard Ratio [HR] = 3.67; p = 0.0001), dental extractions (HR = 23.40; p < 0.0001), and previous BP administration (HR = 2.62; p = 0.0024) were significantly associated with higher MRONJ incidence at multivariate Cox analysis. Although not statistically significant, MRONJ incidence was lower for patients receiving chemotherapy or hormone therapy and higher for those receiving AAs. CONCLUSIONS: The results confirm a clinically relevant incidence of Dmab-induced MRONJ. Dental treatments, especially extraction, during and before Dmab, constitute a serious risk factor. The role of AA concurrent administration deserves further investigations.

Public and patient involvement: a survey on knowledge, experience and opinions among researchers within a precision oncology European project.

BACKGROUND: Patient and Public Involvement (PPI) is slowly but steadily being implemented in all phases of clinical research. As part of the European project "Building Data Rich Clinical Trials" a survey was launched to investigate the knowledge, experiences and opinions on this topic of clinicians and researchers from seven European clinical and non-clinical centers (Cancer Core Europe). METHODS: An invitation to take part in a cross-sectional web survey was sent to 199 clinicians and researchers working in the field of precision oncology. The questionnaire was developed ad hoc because no existing questionnaires met the purpose of this study. The analysis takes account of whether respondents had experience on PPI or not. RESULTS: On a total of 101 respondents, this survey reveals that 76.2% of them knew about PPI before answering the questionnaire, 54.5% had experience in the previous five years and 86.1% were interested in a training course on this topic. PPI knowledge grew together with career seniority (peak of 86.5% for established career professionals), while the group most interested in a course was the early-career professionals (100.0%). Finally, the majority of respondents stated they had no training or education on PPI (67.3% of experienced and 82.6% of not-experienced respondents). CONCLUSIONS: This survey shows that most cancer researchers knew the term PPI, even if only a little more than half of them had any relative experience. Opinions on PPI benefits, negative effects, barriers and requirements differed between the groups of PPI experienced and not-experienced respondents, showing that experience itself can influence respondents' opinions. Most of respondents reported they would prefer a training course based on practical rather than theoretical tools.

Characterizing Different Multidisciplinary Team Models Implemented Within One Comprehensive Cancer Center.

Background: The multidisciplinary approach is considered "best practice" in oncology. Multidisciplinary Teamwork (MDTW) can be broadly classified into Multidisciplinary Team Meetings (MDTM) and Multidisciplinary Cancer Clinics (MDCC; involving also patients), yet both models are heterogeneously implemented. Purpose: This study aims at describing the different MDTW implemented models in a Comprehensive Cancer Center. Methods: All clinical unit directors of the hospital were contacted to identify any MDTW activities the personnel of the unit were involved in. Structured interviews were carried out to collect MDTWs information, ie, type (MDTM vs MDCC), team composition, aims, disease phase, use of Patient Reported Outcome Measures (PROMs). Descriptive analyses and Social Network Analysis (SNA) were performed. Results: Among 38 structured interviews, 25 concerned MDTMs and 13 in MDCCs. Responders were mainly surgeons (35%) and oncologists (29%), 35% of them were team leaders. Teams were mostly composed of physicians only (64% in MDTMs, 69% in MDCCs). Case managers (8% and 31%), palliative care specialists (12% and 23%) and psychologists (20% and 31%) were involved to a lesser extent, mainly when dealing with advanced disease. MDTWs were mainly aimed at integrating the skills of the different specialists (respectively 72% for MDTMs and 64% for MDCCs) and offering the best overall patient care pathway (64%, 61.5%). MDTWs were directed at patients in both diagnostic (72%, 61.5%) and locally advanced/metastatic (32%, 38.4%) disease. PROMs were seldom used (24%, 23%). SNA shows a similar density in the two MDTWs, but in the MDCCs two nodes remain isolated (pathologists and radiologists). Conclusion: Despite a high number of MDTWs for advanced/metastatic disease, there is limited involvement of palliative care specialists, psychologists, and nurses.

'Why should I fill out this questionnaire?' A qualitative study of cancer patients' perspectives on the integration of e-PROMs in routine clinical care.

PURPOSE: There is increasing interest in integrating electronic patient-reported outcomes (e-PROs) into clinical routines in cancer settings. However, little is known about patients' experiences with and perceptions of e-PRO measures (e-PROMs). This study examines patients' experiences with e-PROMS, particularly their perspectives about its usefulness and its implications for the clinical encounter with their doctors. METHOD: A total of 19 individual in-person interviews with cancer patients at a Comprehensive Cancer Center in northern Italy conducted in 2021 inform this study. RESULTS: The findings suggested that, overall, patients had positive attitudes towards data collection using e-PROMs. On the one hand, most patients found the integration of e-PROMs into routine clinical practice as beneficial in treating patients with cancer. The main benefits of e-PROMs according to this group of patients were that: they promoted patient-centred care; could be used to tailor and improve the quality of care through a holistic approach; supported early detection of problematic symptoms; increased patient self-awareness; and contributed to clinical research. On the other hand, many patients did not fully understand the purpose of e-PROMs and some patients were also sceptical about their usefulness in routine clinical practice. CONCLUSIONS: These findings have several practical implications for ensuring the successful implementation of e-PROMs in routine clinical practice. These include the following preconditions: patients are informed about the purposes of data collection; physicians provide feedback to patients about the e-PROMs' results; and that hospital administrators allocate sufficient time for clinical interactions to integrate e-PROMs into routine clinical practice.

Quality of Life in Oncology: Measuring What Matters for Cancer Patients and Survivors in Europe: The EUonQol Project.

Cancer, in Europe, is the second cause of death. In addition, there is an unacceptable variability in terms of access to innovation, quality of care, and outcomes, within and between countries. The European Union has activated an unprecedented initiative to fight cancer by launching Europe's Beating Cancer Plan and the Cancer Mission. The goals are to reduce mortality, increase survival, and ameliorate quality of life by increasing knowledge, improving quality of care, and reducing inequalities through interventions on actionable determinants of variability. A competitive call was launched with the objective to develop and validate a set of quality of life and patient preference measures for cancer patients and survivors, to be used for routine data collection all over Europe. A consortium, the EUonQoL, was funded, including partners from 41 countries with 55 participants. It will start the activities on January 2023 and rresults are expected by December 2024.

Development of the palliative care referral system: proposal of a tool for the referral of cancer patients to specialized palliative care.

BACKGROUND: Early palliative care (PC) has shown beneficial effects for advanced cancer patients. However, it is still debated what criteria to use to identify patients for PC referral. AIM: To document the initial steps of the development of the Palliative Care Referral System (PCRS), a tool to be used by oncologists in clinical practice. METHODS: A multiprofessional working group developed the PCRS based on the results of a scoping literature review on PC referral criteria. PCRS criteria were evaluated by experts via a nominal group technique (NGT). Descriptive statistics were used to summarize expert scores on relevance, appropriateness and perceived feasibility of the criteria proposed. Quotations of participants during the discussion were also reported. RESULTS: Sixteen studies, including PC referral criteria/tools, emerged from the scoping review. Severe symptoms, poor performance status, comorbidities and prognosis were the most commonly used criteria. The PCRS included nine major criteria and nine assessment methods; a scoring procedure was also proposed. Answers to the questionnaire during the NGT showed that five criteria reached full agreement on all items, while four did not, and were then discussed within the group. Participants agreed on the relevance of all criteria and on the appropriateness of methods proposed to assess most of them, while issues were raised about potential feasibility of the overall assessment of the PCRS in clinical practice. CONCLUSION: The PCRS has been developed as an help for oncologists to timely identify patients for specialized PC referral. Since feasibility emerged as the main concern, implementation strategies have to be tested in subsequent studies.

Outpatient palliative care referral system (PCRS) for patients with advanced cancer: an impact evaluation protocol.

INTRODUCTION: Early palliative care (PC) in the clinical pathway of advanced cancer patients improves symptom control, quality of life and has a positive impact on overall quality of care. At present, standardised criteria for appropriate referral for early PC in oncology care are lacking. The aim of this project is to develop a set of standardised referral criteria and procedures to implement appropriate early PC for advanced cancer patients (the palliative care referral system, PCRS) and test its impact on user perception of quality of care received, on patient quality of life and on the use of healthcare resources. SETTING: Selected oncology clinics and PC outpatient clinic. METHODS AND ANALYSIS: A scoping literature review and an expert consultation through a nominal group technique will be used to revise existing referral tools and to develop a new one, the PCRS. 25 patients will be enrolled in a pilot study to assess feasibility of the implementation of PCRS; 10 interviews with patients and healthcare professionals will be carried out to evaluate applicability.A pretest-post-test quasiexperimental study involving 150 patients before implementation of the PCRS and 150 patients after implementation will be carried out.Patient satisfaction with care received, quality of life and use of resources, and caregiver satisfaction with care will also be assessed to explore the impact of the intervention. ETHICS AND DISSEMINATION: Ethical approval for the study has been granted by the Institutional Review board of the Fondazione IRCCS Istituto Nazionale Tumori; approval reference INT201/19.Results will be disseminated through open access publications and through scientific communication presented at national and international conferences. TRIAL REGISTRATION NUMBER: NCT04936568.

Cancer pain: Results of a prospective study on prognostic indicators of pain intensity including pain syndromes assessment.

BACKGROUND: Pain is a prevalent symptom in patients with advanced cancer. Recognition of prognostic factors associated with pain intensity, could help provide better assessment, leading to better pain management. AIM: identifying prognostic factors which could guide improvements on cancer pain classification. DESIGN: a prospective observational study on chronic cancer pain, exploring the association between average mean pain intensity during a 28 days study follow-up and patients' clinical and pain-related characteristics, including pain syndromes. To evaluate these associations, a mixed model was built. SETTING/PARTICIPANTS: Patients attending a Palliative Care and Pain Outpatient Clinic from May 2015 to June 2019 were screened. Patients with moderate to severe cancer pain who were already receiving or needed treatment with third step WHO ladder opioids were enrolled in the study. Data from 342 patients with at least one follow-up visit were analyzed. RESULTS: Pain intensity decreased significantly for all patients during time (p < 0.001). Age, sex, emotional distress, pain duration and neuropathic pain presence evaluated by the Douleur Neuropathique 4 Questions (DN4) questionnaire were not significantly associated to pain intensity. Breakthrough/episodic pain was associated with higher pain intensity during follow-up (p < 0.001). The diagnosis of pain syndrome was overall significantly associated with mean pain intensity during follow-up (p = 0.016). Particularly, the concurrent presence of visceral and soft (p = 0.026) or soft and nervous tissue pain (p = 0.043) were significantly related to worse outcome, whereas pain due to only soft tissue damage with better outcome (p = 0.032). CONCLUSIONS: The recognition of specific pain syndromes may help to better classify cancer pain.

Inflammatory Markers and Radiotherapy Response in Patients With Painful Bone Metastases.

CONTEXT: Inflammation is proposed to influence tumor response in radiotherapy (RT). Clinical studies to investigate the relationship between inflammatory markers and RT response is warranted to understand the variable RT efficacy in patients with painful bone metastases. OBJECTIVES: To evaluate the association between inflammatory markers and analgesic response to RT in patients with painful bone metastases. METHODS: Adult patients from 7 European study sites undergoing RT for painful bone metastases were included in this prospective and longitudinal analysis. The association between RT response and 17 inflammatory markers at baseline, as well as the association between RT response and the changes observed in inflammatory markers between baseline and three and eight weeks after RT, was analyzed with univariate regression analyses. Baseline analyses were adjusted for potential clinical predictors of RT response. RESULTS: None of the inflammatory markers were significantly associated with an upcoming RT response in the analysis of 448 patients with complete baseline data. In patients available for follow-up, the three-week change in TNF (P 0.017), IL-8 (P 0.028), IP-10 (P 0.032), eotaxin (P 0.043), G-CSF (P 0.033) and MCP-1 (P 0.002) were positively associated with RT response, while the three-week change in CRP (P 0.006) was negatively associated. CONCLUSION: Results from this study show an association between RT response and change in pro-inflammatory mediators and indicate that inflammation may be important to achieve an analgesic RT response in patients with painful bone metastases. None of the investigated inflammatory markers were found to be pre-treatment predictors of RT response.

Telemedicine for outpatient palliative care during COVID-19 pandemics: a longitudinal study.

OBJECTIVES: During the COVID-19 pandemic, telemedicine (TM) emerged as an important mean to reduce risks of transmission, yet delivering the necessary care to patients. Our aim was to evaluate feasibility, characteristics and satisfaction for a TM service based on phone/video consultations for patients with cancer attending an outpatient palliative care clinic during COVID-19 pandemics. METHODS: A longitudinal observational study was conducted from April to December 2020. Consecutive patients were screened for video consultations feasibility. Either patients or their caregivers received video/phone consultations registering reason and intervention performed. Those contacted at least twice were eligible for experience of care assessment. RESULTS: Video consultations were feasible in 282 of 572 screened patients (49%, 95% CI 45% to 52%); 112 patients among the 572 had at least two phone/video consultations and 12 of them had one or more video consultations. Consultations were carried out with patients (56%), caregivers (30%) or both (14%). 63% of the consultations were requested by the patients/caregivers. Reasons for consultation included uncontrolled (66%) or new symptom onset (20%), therapy clarifications (37%) and updates on diagnostic tests (28%). Most interventions were therapy modifications (70%) and appointments' rescheduling (51%). 49 patients and 19 caregivers were interviewed, reporting good care experience (average of 1-5 satisfaction score of 3.9 and 4.2, respectively). The majority (83% and 84%) declared they would use TM after the pandemics. CONCLUSIONS: Although feasibility is still limited for some patients, TM can be a satisfactory alternative to in-person visits for palliative care patients in need of limiting access to the hospital.

Knowledge, use and attitudes of healthcare professionals towards patient-reported outcome measures (PROMs) at a comprehensive cancer center.

BACKGROUND: Despite evidence of the positive impact of routine assessment of patient-reported outcome measures (PROMs), their systematic collection is not widely implemented in cancer care. AIM: To assess the knowledge, use and attitudes of healthcare professionals (HCPs) towards PROMs and electronically collected PROMs (ePROMs) in clinical practice and research and to explore respondent-related factors associated with the above dimensions. METHOD: An ad hoc developed online survey was administered to all HCPs employed in clinical activity in an Italian comprehensive cancer center. The survey investigated which PROMs were known and used, as well as HCPs' opinions on the advantages and drawbacks of routine PROM assessment, including electronic assessment (ePROM). Linear and logistic regression models were used for association analyses. RESULTS: Five Hundred Eleven of nine hundred ninety-two invited HCPs (52%) provided analyzable responses. 68% were women, 46% were nurses and 42% physicians, and 52.5% had > 20 years seniority. The average number of PROMs known was six among 17 proposed. All proved to be under-used (< 28%) except unidimensional and multidimensional pain scales (77 and 36%). Respondents expressed an overall positive attitude towards PROMs, with strengths outweighing weaknesses (mean overall scores 3.6 and 2.9, respectively, on a 1-5 scale). 67% of respondents preferred electronic collection over paper and pencil. Profession was associated with knowledge and use (physicians reported knowing more PROMs than other professionals) and with a preference for electronic collection (nurses were less likely to prefer the electronic format than physicians). Senior HCPs were slightly more critical about both PROMs and electronic administration. CONCLUSIONS: This survey indicates an acceptable level of knowledge of common PROM tools but low usage in practice. Based on the generally positive attitude of HCPs, routine implementation of ePROMs can be promoted as long as adequate resources and training are provided. TRIAL REGISTRATION: Not registered.

Development and field testing of a neuro psychomotor multidimensional grid for the assessment of children with cns tumor.

Central Nervous System (CNS) tumors are the most common pediatric solid tumor and development neuro psychomotor (DNPM) therapy can contribute to the rehabilitation of these children. This paper describes the development of a DNPM multidimensional assessment grid for children with CNS tumor (DNPM-CNS grid).The development process included 4 phases: (P1) literature review and grid development (Version 1.0), (P2) two rounds consultations with experts (Version 1.1 and 2.0), (P3) field testing, (P4) final revision (Version 3.0).(P1) The DNPM-CNS grid was developed based on previous tools and manuals and on clinical experience with this patient population. (P2) A total of 52 questionnaires were filled in by experts about relevance of assessment areas, pertinence, comprehensibility and feasibility of the grid. Average scores ranged from 7.6 to 10. (P3) At case level, good inter-rater agreement scores (78%) and limited non-evaluability rates (18%) emerged. At item level, 27% of items reached high disagreement and 26% high not-evaluability rates. The qualitative assessment was judged clinically useful for planning the neuro-oncology rehabilitation treatment and a good feasibility of the DNPM-CNS grid emerged both for preschool and school-age children. (P4) The final version of the grid consists of 8 assessment areas with 133 items.The DNPM-CNS grid is a comprehensive tool that can guide the overall DNPM assessment in a limited amount of time. It can be used as a screening tool to customize more specific assessments. Further research is needed to better characterize grid psychometric properties.Supplemental data for this article is available online at https://doi.org/10.1080/08880018.2021.1948648 .

A Qualitative Study on the Needs of Women with Metastatic Breast Cancer.

Few studies have investigated the needs of patients with metastatic breast cancer (MBC), and none have been conducted in Italy. Three categories of needs have been identified from the literature: information, support, and practical resources. The present study aims to achieve an in-depth understanding of the patients' needs related to the MBC care pathway. In-depth interviews were conducted and analyzed by thematic analysis. The participants were 9 women with MBC (age range 36-74) who were enrolled at the Fondazione IRCCS Istituto Nazionalde dei tumori, in Milan. The analysis enabled us to identify four themes (which reflect the needs of the participants), each divided into numerous sub-themes: (1) the need for clinical recognition, (2) the need for more attention from healthcare professionals, (3) the need for more and better services to be available at the hospital, (4) the need for specific public health policies. Since the metastatic phase of breast cancer seems to elicit additional, specific needs and multi-level management, changes in attitudes and multidisciplinary practices should be tested in order to ascertain how these needs can be met.

Clinical Predictors for Analgesic Response to Radiotherapy in Patients with Painful Bone Metastases.

BACKGROUND: Radiotherapy (RT) reduces pain in about 60% of patients with painful bone metastases, leaving many patients without clinical benefit. This study assesses predictors for RT effectiveness in patients with painful bone metastases. MATERIALS AND METHODS: We included adult patients receiving RT for painful bone metastases in a multicenter, multinational longitudinal observational study. Pain response within 8 weeks was defined as ≥2-point decrease on a 0-10 pain score scale, without increase in analgesics; or a decrease in analgesics of ≥25% without increase in pain score. Potential predictors were related to patient demographics, RT administration, pain characteristics, tumor characteristics, depression and inflammation (C-reactive protein [CRP]). Multivariate logistic regression analysis with multiple imputation of missing data were applied to identify predictors of RT response. RESULTS: Of 513 eligible patients, 460 patients (90 %) were included in the regression model. 224 patients (44%, 95% confidence interval (CI) 39%-48%) responded to RT. Better Karnofsky performance status (Odds ratio (OR) 1.39, CI 1.15-1.68), breast cancer (OR 2.54, CI 1.12-5.73), prostate cancer (OR 2.83, CI 1.27-6.33) and soft tissue expansion (OR 2.00, CI 1.23-3.25) predicted RT response. Corticosteroids were a negative predictor (OR 0.57, CI 0.37-0.88). Single and multiple fraction RT had similar response. The discriminative ability of the model was moderate; C-statistic 0.69. CONCLUSION: This study supports previous findings that better performance status and type of cancer diagnosis predicts analgesic RT response, and new data showing that soft tissue expansion predicts RT response and that corticosteroids is a negative predictor for RT response in patients with painful bone metastases.

Spiritual quality of life in family carers of patients with advanced cancer-a cross-sectional study.

PURPOSE: Caring affects carers' psychological and physical health, mortality, and quality of life (QoL) negatively. Lower spiritual QoL is associated with anxiety and depression, but the spiritual dimension is rarely investigated in carers. The present study aimed to explore which patient- and carer-related characteristics were associated with spiritual QoL in carers of patients with advanced cancer. METHODS: Secondary analyses were conducted using data from a prospective study investigating integration between oncology and palliative care. Adult patients with advanced cancer and their carers were included, and baseline data considering demographics, clinical characteristics, symptoms, social support, and religious meaning-making were registered. Spiritual QoL was measured using the Functional Assessment of Chronic Illness Therapy - Spiritual well-being (FACIT-Sp-12) questionnaire. Associations to spiritual QoL were explored by bivariate and multivariate regression models. RESULTS: In total, 84 carers were included, median age was 62.5 years, 52 (62%) were female, and the average spiritual QoL score was 23.3. In bivariate analyses, higher education, social support, and lower patients' symptom burden were significantly associated with higher spiritual QoL. The multivariate regression model (n=77) had an explained variance (R2) = 0.34 and showed a significant association for social support, higher education, having children < 18 years living at home, and patient's age. CONCLUSION: The study indicates that spiritual QoL in carers were low and were negatively affected by several factors related to both carers and patients. However, there could be other important factors not yet described. Health care professionals should be aware of the known associated factors, as carers who hold these may need extra support.

Neuropathic pain: clinical classification and assessment in patients with pain due to cancer.

ABSTRACT: Neuropathic cancer pain (NcP) is associated with worse treatment responses and specific therapy indications, but a standardized clinical diagnosis of NcP is still lacking. This is a prospective observational study on outpatients with cancer, comparing different clinical approaches with NcP evaluation. A three-step assessment of NcP was performed using DN4 (cutoff of 4), palliative care physician Clinical Impression, including etiology and pain syndrome identification, and Retrospective Clinical Classification by a board of specialists with the IASP Neuropathic Pain Special Interest Group criteria. Neuropathic cancer pain classification was specifically referred to pain directly due to cancer. Three hundred fifty patients were assessed, and NcP prevalence was 20% (95% confidence interval [CI] 15.9%-24.6%), 36.9%, (95% CI 31.6%-42.1%), and 28.6% (95% CI 23.8%-33.9%) according to DN4, Clinical Impression, and Retrospective Clinical Classification, respectively. Cohen's kappa concordance coefficient between DN4 and Retrospective Clinical Classification was 0.57 (95% CI 0.47-0.67), indicating moderate concordance. Higher percentages of discordance were found for specific pain syndromes such as pain due to deep soft tissue infiltration and pain associated with tenesmus. Disagreement among clinicians accounted also for different NcP diagnoses and highlighted lack of homogeneous clinical criteria. Rigorous application of etiological and syndrome diagnosis to explain pain cause, associated with standardized diagnostic criteria and assessment of pain characteristics, that is also specific for the cancer pain condition could improve clinical classification of NcP.
