Characteristics and associations of pain intensity in patients referred to a specialist cancer pain clinic

Symptom Clusters in Patients With Advanced Cancer: A Prospective Longitudinal Cohort Study to Examine Their Stability and Prognostic Significance

This study's purpose was to assess symptom cluster (SC) stability during disease progression and determine their strength of association with survival in patients with advanced cancer . Consecutively eligible patients with advanced cancer not receiving cancer-specific treatment and referred to a Tertiary Palliative Care Clinic were enrolled in a prospective cohort study. At first consultation (D0) and in subsequent consultations at day 15 (D15) and day 30 (D30), patients rated 9 symptoms through the Edmonton Symptom Assessment System scale (0-10) and 10 others using a Likert scale (1-5). Principal components factor analysis with varimax rotation was used to determine SCs at each consultation. Of 318 patients with advanced cancer, 301 met eligibility criteria with a median age of 69 years (range 37-94). Three SCs were identified: neuro-psycho-metabolic (NPM), gastrointestinal, and sleep impairment, with some variations in their constitution over time. Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter median survival was observed continuously for NPM cluster (D0 23 vs. 58 days, P < .001; D15 41 vs. 104 days, P=.004; D30 46 vs. 114 days, P = .002), although the presence of 2 or more SCs on D0 and D15 also had prognostic significance (D0: 21 vs. 45 days, P = .005; D30: 50 vs. 96 days, P = .040). In a multivariable model, NPM cluster (D0 hazard ratio estimate: HR 1.64; 95%CI, 1.17-2.31; P = .005; D15 HR: 2.51; 95%CI, 1.25-5.05; P = .009; D30 HR: 3.9; 95%CI, 1.54-9.86; P = .004) and hospitalization (D0 HR: 2.27; 95%CI, 1.47-3.51; P < .001; D15 HR: 2.43; 95%CI, 1.18-5.01; P = .016; D30 HR: 3.41; 95%CI, 1.35-8.62; P = .009) were independently and significantly associated with worse survival. Three clinically relevant SCs were identified, and their constitution had small variations, maintaining a stable set of nuclear symptoms through disease progression. Presence of the NPM cluster and hospitalization maintained their prognostic value over time.

Effects of self-management interventions for cancer patients with pain: A systematic review of randomised controlled trials

AIMS

To evaluate the effects of self-management interventions targeting individuals with cancer-related pain on pain intensity, self-efficacy, quality of life (QoL), pain medication adherence, and pain-related knowledge and provide recommendations for the content and format of self-management interventions based on the existing evidence.

DESIGN

A systematic review of randomised controlled trials (RCTs) and narrative synthesis.

DATA SOURCES

A search of six electronic databases, including Medline, PsycINFO, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science and Scopus.

REVIEW METHODS

This systematic review followed the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies published from January 2011 to March 2022 in English were retrieved. The Cochrane Risk of Bias Tool was used to assess quality. Data were summarised using narrative synthesis.

RESULTS

This systematic review included six RCTs involving 748 patients with cancer-related pain. The results support the effectiveness of the intervention on QoL and pain-related knowledge. Mixed results were observed in the effectiveness on pain intensity, self-efficacy and medication adherence. Overall, the quality of the evidence was low. The content of self-management interventions varied across studies but with similar formats (face-to-face coaching and telephone follow-up).

CONCLUSION

The existing evidence supports the effectiveness of self-management interventions on pain-related knowledge and QoL. Further high-quality RCTs are needed to determine the most effective interventions.

RELEVANCE TO CLINICAL PRACTICE

Self-management is recommended to improve cancer patients' pain awareness, self-management behaviour and adaptability. Components for self-management of cancer pain, including patient attitude and knowledge assessment, nurse coaching and counselling, reinforcement during follow-up period, and provision of supplementary materials on pain management and medication adherence, could be covered in the intervention. In the future, it is worthwhile exploring an effective intervention using Internet-based information technology, for example WeChat, to aid the delivery of self-management intervention.

The Effect of Hypnosis on the Intensity of Pain and Anxiety in Cancer Patients: A Systematic Review of Controlled Experimental Trials

BACKGROUND

Pain is a common symptom in cancer patients. Hypnosis is considered one of the most recognized non-pharmacological techniques in pain management. In oncology, this technique can be used as a complementary treatment to reduce the level of pain and anxiety. The objective of this study is to systematically review and evaluate controlled clinical trials (CCTs) examining the effect of hypnosis on the intensity of pain, and anxiety in cancer patients.

METHODS

A systematic review was conducted according to the recommendations of the "Preferred reporting items for systematic reviews and meta-analyses" (PRISMA). The Cochrane systematic review database, the abstract databases, Scopus, PubMed, Google Scholar, and Cochrane Library have been systematically reviewed from 2005 to 2018.

RESULTS

Eleven CCT with a total of 1182 participants met the inclusion criteria and were included in this review. The participants were mainly women (n = 968). Their average age alternates between 48 and 58 years. Perceived pain was measured primarily by visual analog scale (VAS)/numerical pain rating scale (NPRS), which showed that anxiety was measured by Hospital Anxiety and Depression scale (HADS). Hypnosis-related anxiety and pain decreased significantly with respect to usual treatment.

CONCLUSIONS

Evidence suggests promising results of hypnosis on the management of pain, and anxiety levels in the vast majority of cancer patients. Therefore, because of the exploratory design and high risk of bias, the effectiveness of hypnosis or hypnotherapy in reducing pain and anxiety levels remains unclear. There is a need for more rigorous randomized controlled trials (RCTs).

Compromised end-of-life syndrome: Concept development from the condition of adults and older adults in palliative care

PURPOSE

This study aimed to develop the nursing diagnosis concept "compromised end-of-life syndrome" in palliative care.

METHODS

The authors used the integrative strategy by Meleis to develop the concept in this study and identifying clinical indicators from a literature review. For data organization, we applied the Preferred Reporting Items for Systematic Reviews and Metanalysis (PRISMA).

FINDINGS

Some clusters of unpleasant signs and symptoms in palliative care patients at the end of life, such as pain, dyspnea, depression, constipation, and anxiety, were identified. Through conceptualization, the authors propose a new nursing diagnosis, "compromised end-of-life syndrome." The manuscript includes a model case of a patient with nursing diagnosis syndrome as a clinical example.

CONCLUSIONS

Simultaneous patterns of signs and symptoms present in the literature reinforce the utility of the proposition of end-of-life syndrome as a nursing diagnostic construct.

IMPLICATIONS FOR NURSING PRACTICE

The concept development related to patients' unpleasant signs and symptoms critically ill at palliative care supports the proposition of a new nursing diagnosis relevant to selecting adequate nursing interventions and nursing outcomes. Some clusters of unpleasant signs and symptoms in palliative care patients at the end of life, such as pain, dyspnea, depression, constipation, and anxiety were identified. Conceptualization was used to propose a new nursing diagnosis, "compromised end-of-life syndrome." A model case of a patient with nursing diagnosis syndrome is described as a clinical example.

CONCLUSION

Simultaneous patterns of signs and symptoms present in the literature reinforce the utility of the proposition of end-of-life syndrome as nursing diagnostic construct.

IMPLICATIONS FOR NURSING PRACTICE

The concept development related to patients' unpleasant signs and symptoms critically ill at palliative care supports the proposition of a new nursing diagnosis relevant to selecting adequate nursing interventions and nursing outcomes.

Prevalence of neuropathic pain in terminally ill patients with cancer admitted to a general ward: a prospective observational study

Objectives

To determine the prevalence of neuropathic pain among terminally ill patients with cancer admitted to a general ward, using the International Association for the Study of Pain algorithm.

Methods

This prospective observational study was conducted at a tertiary care center. We enrolled terminally ill patients with cancer admitted to the general ward between September 2018 and September 2019. On the day of consultation with our palliative care team, pain management clinicians examined and diagnosed neuropathic pain using the International Association for the Study of Pain diagnostic criteria.

Results

A total of 108 patients were enrolled during the study period. The median age was 69 years (interquartile range [IQR] 58.3–76.8 years), 72 patients (66.7%) were men, and the median survival time was 33 days (IQR 14.3–62 days). Of the 108 patients, 33 (30.6%) had neuropathic pain. Patients with neuropathic pain had more severe pain than those without neuropathic pain.

Conclusions

The prevalence of neuropathic pain in terminally ill patients with cancer admitted to a Japanese general ward was 30.6%. Further studies are warranted to elucidate whether the accurate diagnosis of neuropathic pain can improve pain control and/or patient conditions.

Perceived Quality of Nursing Care Among Cancer Patients Attending Hawassa University Comprehensive Specialized Hospital Cancer Treatment Center; Hawassa Southern Ethiopia: Cross-Sectional Study

Background

Cancer has become one of the most common and the second leading cause of death. According to grounded theory, quality care is meeting all the needs of the patients. Low-quality nursing care relates omission of nursing care required to meet patients' need. Quality of nursing care in oncologic setting was nursing practice area where studies are limited.

Objective

The aim of the study was to assess the perceived quality of nursing care among patients with cancer attending Hawassa University comprehensive specialized Hospital.

Methods

A quantitative Cross-sectional study was conducted. Among the proposed 422 patients with cancer, using a simple random sampling technique 415 patients were included in this study. Seven data were discarded due to incompleteness and inconsistency between collected data and patient medical record. Data were collected using structured questionnaires and Quality of Oncology Nursing Care Scale. We carried out statistical analysis using SPSS V-20. We used descriptive analysis to examine the quality of oncology nursing care.

Results

The mean age of patients was 42.51 (±14.24) years, among patients diagnosed with cancer more than one-third 148 (35.70%) had breast cancer. The majority of patients with cancer 173 (41.70%) were in stage-III. Nearly two-third 266 (64.10%) of patients were on chemotherapy. Among study participants on treatment, 249 (60.00%) perceived they received good quality of nursing care. The mean score related to the domain of support and confirmation is 62.73 ± 7.26. In terms of spiritual care, the mean score is 21.03 ± 5.37.

Conclusion

The perceived quality of nursing care was high however not all domains of oncology care were achieved. We recommend Detail and focused study to explore important predictors’ quality nursing care.

The pattern of change in opioid and adjuvant prescriptions for cancer pain before and after referral to a comprehensive program in the Palliative Care Center in Kuwait

Background

Cancer-related pain is a complicated symptom that often coincides with fatigue, depression, and anxiety. Although many safe treatments are available, inadequate control of Cancer-related pain continues to lead to suffering in cancer patients. This study’s aim is to describe pain control, and the pattern of change in opioid and adjuvant medication prescriptions, before and after referral to the Palliative Care Center.

Methods

We conducted a prospective cohort study in adult cancer patients the Palliative Care Center between January 1, 2016 and December 30, 2017. We measured pain intensity and other associated symptoms via the Revised Edmonton Symptom Assessment System (ESAS-r) and documented detailed analgesics and adjuvant medication history before starting any palliative care and on days 0, 3, 6, and 14.

Results

The analysis included 240 patients whose cancer-related pain, anxiety, and depression scores meaningfully improved by day 6. The changes in the median (interquartile ranges) of Cancer-related pain, anxiety, and depression scores from day 0 to day 6 were: 6 (4–8) to 3 (1–4); 6 (4–9) to 2 (1–4); and 3 (2–6) to 2 (1–4), respectively, with p < 0.001 for all. Morphine was the most common opioid administered; the percentage using it increased from 20.4% (n = 49) before referral to 49.6% (n = 119) on day 6 (p < 0.001). The median morphine equivalent daily dose decreased from a median (interquartile ranges) of 60(31–93) mg/day before referral to 34(22–66) mg/day on day 6 (p < 0.001). There was also a statistically significant increase in the percentage of patients taking adjuvant medications, from 38.8% before referral to 84.2% on day 6 (p < 0.001). Comparing D0 to D6, the number of patients using Gabapentinoids significantly increased from 57(23.75%) to 79(32.9%) (p < 0.001), amitriptyline dramatically increased from 14 (5.8%) to 44 (18.3%) (p < 0.001), and other antidepressant drugs increased from 15 (6.2%) to 34 (14.1%) (p < 0.001).

Conclusion

After referral to the Palliative Care Center, patients’ pain and other symptoms scores decreased significantly, even with lower median morphine equivalent daily doses, arguably through more appropriately directed opioid use. This is evidence for the effectiveness of the comprehensive program at the Palliative Care Center in Kuwait.

Usefulness of painDETECT and S-LANSS in identifying the neuropathic component of mixed pain among patients with tumor-related cancer pain

PURPOSE

Tumor-related cancer pain often comprises mixed pain with both nociceptive and neuropathic components. Whether tumor-related cancer pain includes a neuropathic component impacts the therapeutic strategy. The aim of this cross-sectional study was to investigate the usefulness of two screening tools for neuropathic pain, painDETECT and Self-Report Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS), in identifying the neuropathic component of mixed pain among patients with tumor-related cancer pain.

METHOD

This cross-sectional study recruited consecutive inpatients and outpatients at a single site. The diagnostic accuracy of painDETECT and S-LANSS was evaluated using receiver operating characteristic curve analysis and classification probability.

RESULTS

Of the study group, 106 patients had tumor-related cancer pain. Analyses of the nociceptive and mixed pain groups (n = 104) showed that neither painDETECT nor S-LANSS had satisfactory areas under the curve (AUCs) for identifying the neuropathic component of mixed pain (0.59 for painDETECT and 0.56 for S-LANSS). By pain intensity, the AUC for painDETECT was significantly higher in the mild pain group than in the moderate or severe pain group (0.77 vs. 0.43, P = 0.002). All parameters of classification probability for both tools were higher in the mild pain group than in the moderate or severe pain group.

CONCLUSIONS

painDETECT and S-LANSS could not identify the neuropathic component of mixed pain among patients with tumor-related cancer pain, especially when pain was moderate or severe. Contrarily, these screening tools might be useful for identifying the neuropathic component of mixed pain for mild pain.

Which factors can aid clinicians to identify a risk of pain during the following month in patients with bone metastases? A longitudinal analyses

PURPOSE

Explore clinical factors associated with higher pain intensity and future pain in patients with bone metastases to identify patients who can benefit from closer follow-up or pain-modifying interventions.

METHODS

This is a secondary analysis of 606 patients with bone metastases included in a multicenter longitudinal study. The dependent variables were "average pain" and "worst pain" in the last 24 h (0-10 NRS). Twenty independent variables with potential association to pain intensity were selected based on previous literature. Cross-sectional analyses were performed with multiple linear regression to explore factors associated with pain intensity at baseline. Longitudinal data were analyzed with a generalized equation models to explore current factors associated with pain intensity at the next visit in 1 month.

RESULTS

Current pain intensity (p < 0.001), sleep disturbances (p 0.01 and 0.006), drowsiness (p 0.003 and 0.033) and male gender (p 0.045 and 0.001) were associated with higher average and worst pain intensity in 1 month. In addition, breakthrough pain was related to higher worst pain intensity (p 0.003) in 1 month. The same variables were also associated with higher average pain intensity at baseline.

CONCLUSION

Higher current pain intensity, sleep disturbances, drowsiness, male gender, and breakthrough pain are factors associated with higher pain intensity in patients with bone metastases at the next follow-up in 1 month. These factors should be assessed in clinical practice and may aid clinicians in identifying patients that can benefit from closer follow-up or interventions to prevent lack of future pain control.

A systematic review of the risk factors for clinical response to opioids for all-age patients with cancer-related pain and presentation of the paediatric STOP pain study

BACKGROUND

Inter-patient variability in response to opioids is well known but a comprehensive definition of its pathophysiological mechanism is still lacking and, more importantly, no studies have focused on children. The STOP Pain project aimed to evaluate the risk factors that contribute to clinical response and adverse drug reactions to opioids by means of a systematic review and a clinical investigation on paediatric oncological patients.

METHODS

We conducted a systematic literature search in EMBASE and PubMed up to the 24th of November 2016 following Cochrane Handbook and PRISMA guidelines. Two independent reviewers screened titles and abstracts along with full-text papers; disagreements were resolved by discussion with two other independent reviewers. We used a data extraction form to provide details of the included studies, and conducted quality assessment using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

RESULTS

Young age, lung or gastrointestinal cancer, neuropathic or breakthrough pain and anxiety or sleep disturbance were associated to a worse response to opioid analgesia. No clear association was identified in literature regarding gender, ethnicity, weight, presence of metastases, biochemical or hematological factors. Studies in children were lacking. Between June 2011 and April 2014, the Italian STOP Pain project enrolled 87 paediatric cancer patients under treatment with opioids (morphine, codeine, oxycodone, fentanyl and tramadol).

CONCLUSIONS

Future studies on cancer pain should be designed with consideration for the highlighted factors to enhance our understanding of opioid non-response and safety. Studies in children are mandatory.

Strong opioid prescription in cancer patients in their final year of life: A population-based analysis using a Taiwanese health insurance database

AIM

Pain assessment and management have been important criteria in hospital accreditation in Taiwan since 2007. We used a Taiwanese health insurance database to determine factors influencing patterns of strong opioid use in cancer patients in their final 12 months of life.

METHODS

Data from patients with cancer in Taiwan outpatient clinics with cancer-related deaths between 2008 and 2011 were included in the analysis. Strong opioid prescription data from the last 12 months of each patient's life, as well as patient, physician, and hospital characteristics, were collected from the National Health Insurance Research Database.

RESULTS

Among 162 679 patients, more were male (63.6%) than female (36.4%) and almost half (49.3%) were ≥70 years old. Most (44.9%) patients had gastrointestinal cancer. More than one-third (35.4%) of patients were prescribed strong opioids during the 12 months before death, and more than half (53.2%) of those prescribed opioids received them in the 3 months before death. Median duration of strong opioid use was 81 days before death. Patients with head/neck cancer (52.8%) or who were treated in hematology and oncology departments (45.8%) were most likely, and patients with gastrointestinal cancer (hazard ratio = 0.65; 95% confidence interval, 0.64-0.67) or treated in gastroenterology departments (hazard ratio = 0.88; 95% confidence interval, 0.84-0.93) were least likely to be prescribed strong opioids.

CONCLUSION

Strong opioid prescriptions varied among patients with different cancer diagnoses and physicians. Information from this study can guide efforts to improve patient and physician education about cancer pain management.

It summarizes papers published during 2016 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia, stress and social status, tolerance and dependence, learning and memory, eating and drinking, drug abuse and alcohol, sexual activity and hormones, pregnancy, development and endocrinology, mental illness and mood, seizures and neurologic disorders, electrical-related activity and neurophysiology, general activity and locomotion, gastrointestinal, renal and hepatic functions, cardiovascular responses, respiration and thermoregulation, and immunological responses.

Cancer Pain With a Neuropathic Component: A Cross-sectional Study of Its Clinical Characteristics, Associated Psychological Distress, Treatments, and Predictors at Referral to a Cancer Pain Clinic

CONTEXT

In patients with cancer pain, identifying a neuropathic pain component (NPC) may inform the selection of subsequent therapeutic interventions.

OBJECTIVES

The objective of this study was to determine the prevalence, clinical characteristics, associated psychological distress, pre-referral treatment, and predictors of cancer pain with an NPC in patients referred to a cancer pain clinic.

METHODS

Participants had standard assessments and documentation: Brief Pain Inventory ratings, presence of an NPC, based on a Douleur Neuropathique 4 (DN4) (neuropathic pain screening scale) score ≥4 combined with a physician's clinical assessment (blinded to DN4 result), the Hospital Anxiety Depression Scale, and Emotion Thermometer scores. Logistic regression analyses were used to determine predictors associated with an NPC.

RESULTS

Of 371 study participants, 120 (32.3%) had a designated NPC. Overall, psychological distress indices were similar in the NPC and nociceptive pain groups, except for a Hospital Anxiety and Depression Scale >7 score that was proportionately higher (74% vs. 63%, P = 0.03) in the nociceptive group. The final multivariable logistic regression model generated the following NPC predictors and their respective odds ratios (95% CIs): recent chemotherapy, 2.93 (1.63-5.26); recent surgery, 3.65 (2.03-6.59); adjuvant analgesic use, 2.93 (1.66-5.17); episodic incident pain, 2.63 (1.44-4.84); episodic breakthrough pain, 3.67 (2.00-6.73); pain duration three or more months, 2.35 (1.36-4.06); higher pain intensity, 1.47 (1.24-1.74); and pelvic or perineal pain location, 2.75 (1.09-6.96).

CONCLUSION

One in three patients with cancer have an NPC, which is independently associated with recent chemotherapy, surgery, adjuvant analgesic use, episodic incident and breakthrough pain, longer pain duration, higher pain intensity, and pelvic or perineal pain location.

Adequacy of cancer-related pain management and predictors of undertreatment at referral to a pain clinic

Background

Several guidelines have advocated the need for adequate cancer-related pain (CRP) management. The pain management index (PMI) has been proposed as an auditable measure of the appropriateness for analgesic therapy.

Objectives

To determine the adequacy of CRP management based on the PMI status and its patient-related predictors at the point of referral to a pain clinic (PC).

Methods

Consecutive patients referred to a PC had standardized initial assessments and status documentation on the Brief Pain Inventory (BPI) ratings; pain mechanism, using a neuropathic pain diagnostic questionnaire (the Douleur Neuropathique 4 tool); episodic pain; oral morphine equivalent daily dose; the Hospital Anxiety Depression Scale and the Emotion Thermometer scores; and cancer diagnosis, metastases, treatment, and pain duration. Predictors of “negative PMI status” [PMI(−)] were examined in logistic regression models. Variables with p<0.25 in an initial bivariable analysis were entered into a multivariable model.

Results

Of 371 participants, 95 (25.6%) had PMI(−), suggesting undertreatment of CRP. Both female sex and higher scores on the BPI’s “interference with general activity” more strongly predicted PMI(−). Patients who received either radiotherapy or one or more adjuvant analgesics prior to the initial consultation at the PC, those who had neuropathic pain, those who had a greater need for emotional help, and those with higher BPI’s “relief ” scores were all less likely to be PMI(−).

Conclusion

The potential burden of patient and family distress associated with suboptimal CRP management in one in four patients should generate major public health concern and prompt appropriate educational and health policy measures to address the deficit.

Patterns of opioid use in sickle cell disease

Pain, the hallmark complication of sickle cell disease (SCD), is largely managed with opioid analgesics in the United States, but comprehensive data regarding the long-term use of opioids in this patient population is lacking. The pain medication prescription records from a cohort of 203 SCD patients were analyzed. Twenty-five percent were not prescribed opioid medications while 47% took only short-acting opioids, 1% took only long-acting opioids, and 27% took a combination of short-acting and long-acting opioids. The median (interquartile range) daily opioid dose was 6.1 mg (1.7-26.3 mg) of oral morphine equivalents, which is lower than the published opioid use among patients with other pain syndromes. The dose of opioids correlated with the number of admissions due to vaso-occlusive crisis (VOC) (r = 0.53, P < 0.001). When the patients were grouped into quartiles based on daily dose opioid use, a logistic regression model showed that history of avascular necrosis (AVN) (OR: 2.87, 95% CI: 1.37-6.02, P = 0.005), 25-OHD levels (OR: 0.59, 95% CI: 0.38-0.93, P = 0.024) and total bilirubin concentration (OR: 0.64, 95% CI: 0.42-0.99, P = 0.043) were independently associated with opioid use quartiles. In conclusion, doses and types of opioid medications used by adult SCD patients vary widely. Our findings implicate AVN and lower vitamin D levels as factors associated with higher opioid use. They also suggest an association of higher bilirubin levels, possibly suggesting higher hemolytic rate, with lower opioid use. Am. J. Hematol. 91:1102-1106, 2016. © 2016 Wiley Periodicals, Inc.

Symptom clusters and survival in Portuguese patients with advanced cancer

This study aimed to identify clusters of symptoms, to determine the patient characteristics associated with identified, and determine their strength of association with survival in patients with advanced cancer (ACPs). Consecutively eligible ACPs not receiving cancer‐specific treatment, and referred to a Tertiary Palliative Care Clinic, were enrolled in a prospective cohort study. At first consultation, patients rated 9 symptoms through the Edmonton Symptom Assessment System (0–10 scale) and 10 others using a Likert scale (1–5). Principal component analysis was used in an exploratory factor analysis to identify. Of 318 ACPs, 301 met eligibility criteria with a median (range) age of 69 (37–94) years. Three SCs were identified: neuro‐psycho‐metabolic (NPM) (tiredness, lack of appetite, lack of well−being, dyspnea, depression, and anxiety); gastrointestinal (nausea, vomiting, constipation, hiccups, and dry mouth) and sleep impairment (insomnia and sleep disturbance). Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter survival was observed for patients with the NPM cluster (58 vs. 23, P < 0.001), as well as for patients with two or more SCs (45 vs. 21, P = 0.005). In a multivariable model for survival at 30‐days, age (HR: 0.98; 95% CI: 0.97–0.99; P = 0.008), hospitalization at inclusion (HR: 2.27; 95% CI: 1.47–3.51; P < 0.001), poorer performance status (HR: 1.90, 95% CI: 1.24–2.89; P = 0.003), and NPM (HR: 1.64; 95% CI: 1.17–2.31; P = 0.005), were associated with worse survival. Three clinically meaningful SC in patients with advanced cancer were identifiable. The NPM cluster and the presence of two or more SCs, had prognostic value in relation to survival.

Breast cancer survivors suffer from persistent postmastectomy pain syndrome and posttraumatic stress disorder (ORTHUS study): a study of the palliative care working committee of the Turkish Oncology Group (TOG)

PURPOSE

Persistent postmastectomy pain syndrome (PMPS) is one of the most important disturbing symptoms. Posttraumatic stress disorder (PTSD) is an anxiety disorder which is characterized by reactions to reminders of the trauma that has been experienced. The purpose of this study is to evaluate the predictors of PMPS and PTSD in Turkish breast cancer survivors and the correlation between PMPS and PTSD.

METHOD

The study is designed as a multicenter survey study. Breast cancer patients in remission were evaluated. Patients were evaluated with structured questionnaires to assess the PMPS and clinical parameters associated with it. The Turkish version of the posttraumatic stress disorder checklist-civilian version (PCL-C) was used.

RESULTS

Between February 2015 and October 2015, 614 breast cancer survivors in outpatient clinics were evaluated. The incidence of PMPS documented is 45.1 %. In the multivariate analysis low income, presence of PTSD and <46 months after surgery were associated with increased risk of PMPS. PTSD was documented in 75 %, and the mean PCL-C score was 32.4 ± 11.1. PMPS and being married at the time of the evaluation were linked with PTSD.

CONCLUSIONS

It is the first data about the association between PMPS and PTSD. The clinicians should be aware of PMPS and PTSD in breast cancer survivors.
