The role of spirituality in pain experiences among adults with cancer: an explanatory sequential mixed methods study.

PURPOSE: Foundational research demonstrates that spirituality may affect the way people with cancer experience pain. One potential route is through alterations in thoughts and beliefs, such as pain-related catastrophizing. The purpose of this study is to understand whether spirituality impacts pain experiences through pain-related catastrophizing. METHODS: This explanatory sequential mixed methods study was informed by an adapted Theory of Unpleasant Symptoms. Data were collected via online surveys (N = 79) and follow-up qualitative interviews (N = 25). Phase 1 employed Empirical Bayesian analysis. Phase 2 used deductive content analysis. Phase 3 involved creating a mixed methods joint display to integrate findings and draw meta inferences. RESULTS: Results indicate that total spiritual well-being was directly negatively associated with pain-related catastrophizing, and indirectly negatively associated with the outcomes of pain interference, pain severity, and pain-related distress. Qualitative categories highlight the supportive role of spirituality when facing pain, while also shedding light on the limitations of spirituality in the context of some pain (i.e., severe, neuropathic, and/or chronic). Mixed methods findings reveal the importance of spirituality for some people as they face cancer and cancer-related pain, as well as the need for integrating spirituality as part of a larger pain management plan. CONCLUSIONS: This research advances supportive cancer care by exploring the complex role of spirituality in pain experiences. Findings will inform further exploration into the role of spirituality in supporting holistic symptom management in the context of cancer, as well as developing and testing interventions to enhance spirituality and address symptom-related suffering.

Epitranscriptomic profiling of N4-acetylcytidine-related RNA acetylation in the spinal dorsal horn of rat with cancer-induced bone pain.

Recently, epigenetics involved in the regulation of gene expression has become a research hotspot. This study evaluated N4-acetylcytidine (ac4c) RNA acetylation in the spinal dorsal horn (SDH) of rats with cancer-induced bone pain (CIBP). The ac4C-specific RIP sequencing and NAT10-specific RIP sequencing were performed to identify the differences in ac4C acetylation and gene expression in the SDH between CIBP and sham groups, the relationship with the acetylation-modifying enzyme NAT10, and association analysis was performed. By interfering with the NAT10 expression, the relationship between some up-regulated genes and ac4C acetylation in CIBP was verified. In this study, we demonstrated that bone cancer increases the levels of NAT10 and the overall acetylation, inducing differential ac4C patterns in the SDH of rats. Through verification experiments, it was found that ac4C acetylation of some genes is regulated by NAT10, and differential ac4C patterns in RNA determine the expression of this RNA. We exposed that some CIBP-related gene expression was altered in the SDH of rats, which was regulated by differentially expressed ac4C acetylation.

Management of cancer pain due to bone metastasis.

Bone metastases frequently occur in patients with cancer. Skeletal-related events (SREs), including pain, impaired mobility, hypercalcemia, pathological fracture, spinal cord and nerve root compression, and bone marrow infiltration, can decrease the quality of life of the patients and increase the risk of morbidity. The mechanism of pain due to bone metastasis is complicated and involves various interactions among tumor cells, bone cells, activated inflammatory cells, and bone-innervating neurons. Cancer pain due to bone metastasis can be crippling and a chronic state that causes sarcopenia. For pain management, it is important to diagnose whether the pain is based on background pain or breakthrough pain due to bone metastasis. In addition, the management goal of cancer pain due to bone metastasis is not only to achieve pain relief but also to prevent pain progression and SREs. Pain mechanisms should be applied to achieve optimal management. This review aims to discuss the mechanisms of cancer pain due to bone metastasis and review the recommended drug therapies.

Efficacy of reconstituted intravenous fentanyl to sublingual solution versus oral morphine syrup for breakthrough pain among patients with chronic gynecologic cancer pain: A randomized, double-blind, placebo-controlled trial.

Rapid-acting fentanyl formulations are superior to oral morphine (OM) syrup in controlling breakthrough pain among patients with cancer, but they are expensive and unavailable in many countries. OBJECTIVE: To evaluate the efficacy of reconstituted intravenous fentanyl to sublingual solution (IFS) in relieving breakthrough pain as compared with OM. METHODS: In this randomized, double-blind, double-dummy, placebo-controlled trial, patients with gynecologic cancer aged ≥18 years experiencing chronic cancer pain with breakthrough pain were enrolled. Patients were randomly allocated (1:1) to receive either 50 µg IFS or 5 mg OM. Pain intensity level was assessed at 5, 15, 30, 45, 60, and 120 min after treatment. The primary outcome was the reduction in pain intensity at 15 min in the intention-to-treat population (ClinicalTrials.gov, NCT05037539). RESULTS: Between June 15, 2021 and December 30, 2021, 40 participants were equally and randomly assigned to receive IFS or OM. The primary outcome was significantly higher in the IFS group (4.25 vs. 1.05, p < 0.0001). The secondary outcomes also showed higher reduction in pain intensity at 5 min in the IFS group. Subsequent breakthrough pain did not differ between the two groups. However, the reduction in pain was lower in the IFS group at 45, 60, and 120 min, where pain was classified as mild. No severe adverse effects were observed in both groups. Burning sensation without noticeable lesion was found in 20% of the IFS group. CONCLUSION: IFS can reduce early breakthrough pain. IFS may be considered for breakthrough pain when rapid-acting fentanyl formulations are unavailable.

Intrathecal drug delivery for cancer pain at the end of life: a case study.

Two-thirds of patients with advanced cancer have pain and, of these, approximately 10-20% do not respond to conventional pain management approaches. This case study concerns a hospice patient who received intrathecal drug delivery for intractable cancer pain at the end of life. This involved working in partnership with a hospital-based interventional pain team. Despite side-effects and complications associated with intrathecal drug delivery and the requirement for inpatient nursing care, intrathecal drug delivery was the best option for the patient. The case identifies the importance of a patient-centred approach to decision-making, effective partnerships between hospice and acute hospital teams, and nurse education as key factors contributing to the provision of safe and effective intrathecal drug delivery.

Methadone as First-line Opioid for the Management of Cancer Pain.

AIM: The aim of this study was to assess the efficacy and adverse effects of methadone when used as first-line therapy in patients that are either receiving low doses of opioids or none. METHODS: Patients with advanced cancer were prospectively assessed. Opioid-naive patients (L-group) were started with methadone at 6 mg/day. Patients receiving weak or other opioids in doses of <60 mg/day of OME (H-group) were started with methadone at 9 mg/day. Methadone doses were changed according to the clinical needs to obtain the most favorable balance between analgesia and adverse effects. Edmonton Symptom Asssement Score (ESAS), Memorial Delirium Assessment Score (MDAS), doses of methadone, and the use of adjuvant drugs were recorded before starting the study treatment (T0), 1 week after (T7), 2 weeks after (T14), 1 month after (T30), and 2 months after (T60). Methadone escalation index percent (MEI%) and in mg (MEImg) were calculated at T30 and T60. RESULTS: Eighty-two patients were assessed. In both groups H and L, there were significant changes in pain and symptom intensity at the different times during the study. Adverse effects as causes of drop-out were minimal. Mean MEImg was 0.09 (SD 0.28) and 0.02 (SD 0.07) at T30 and T60, respectively. MEI% was 1.01 (SD 3.08) and 0.27 (SD 0.86) at T30 and T60, respectively. CONCLUSION: Methadone used as a first-line opioid therapy provided good analgesia with limited adverse effects and a minimal opioid-induced tolerance.

Nutritional Risk and Assessment for Patients with Cancer Pain.

BACKGROUND: The incidence of nutritional risk and malnutrition are high in patients with cancer pain. It is very important to choose an effective tool to identify these patients promptly. However, few studies have discussed this issue. The primary objective of this study is to clarify the similarities and differences between the two nutritional screening and assessment tools, and to estimate the anthropometry and biochemical indicators of the patients with cancer pain, with a view to provide help for treatment of these patients. METHOD: Data of 146 patients with cancer pain were collected from August 2018 to May 2019 in the Pain Therapy Department of Tianjin Cancer Hospital. The information of numerical rating scale (NRS), nutritional risk screening-2002 (NRS-2002), patient-generated subjective global assessment (PG-SGA), anthropometry and biochemical indicators were collected for pain assessment, nutritional risk screening, and nutritional status assessment. RESULTS: NRS scores had a positive correlation with NRS-2002 (R = 0.273, P = 0.001) and PG-SGA (R = 0.341, P = 0.000) separately. NRS-2002 and PG-SGA had a significant positive correlation with each other (R = 0.468, P = 0.000). NRS-2002 was finished in a shorter time period (4.2 ± 0.8 min vs. 12.8 ± 0.8 min, P = 0.001), while PG-SGA had a higher detection rate of malnutrition (86.3% vs. 65.8%). In the stepwise multiple regression analysis, NRS (0.258, P = 0.001), PA (-0.297, P = 0.000), TP (0.178, P = 0.030) are the indicators of NRS-2002; and NRS (0.317, P = 0.000), PA (ß = 0.288, P = 0.000) and BMI (-0.281, P = 0.000) are the related variables of PG-SGA. The kappa coefficient was lower than 0.4 (kappa value = 0.396) when choosing the score of NRS-2002 ≥ 3 and PG-SGA ≥ 9 as the diagnostic criteria. If choosing the score of NRS-2002 ≥ 2 and PG-SGA ≥ 9, both the correlation coefficient (R = 0.699, P = 0.000) and the kappa coefficient (kappa value = 0.698, P = 0.000) became more coefficient. CONCLUSIONS: Both NRS-2002 and PG-SGA could identify patients with nutritional risk and malnutrition accurately. NRS-2002 is simpler and takes less time to finish, while PG-SGA is more cumbersome with a higher detection rate of malnutrition. NRS, PA, TP and BMI are the most important reference indicators predicting on nutritional risk index and malnutrition status. We recommend NRS-2002 ≥ 2 as the diagnostic criteria in order to avoid missing the patients with nutritional risk.

Rapid titration with oral sustained-release morphine plus subcutaneous morphine in a multi-center, randomized control study of cancer patients with moderate to severe cancer pain.

BACKGROUND: Pain is one of the most common concomitant symptoms among cancer patients. Pharmacologic agents are regarded as a cornerstone of cancer pain management. 'Dose titration' with short-acting morphine is widely accepted. Such a titration method is very complicated. The analgesic background establishment is often delayed. Titration based on sustained-release opioids is also recommended, but the onset of analgesic effect requires hours, whereas the rescue analgesia is always needed. This study evaluated the optimized morphine titration scheme with a simultaneous combination of sustained-release morphine and subcutaneous morphine. METHODS: In a multicenter, 7-day, randomized controlled study, patients with moderate to severe cancer pain were assigned to receive either sustained-release morphine and subcutaneous morphine simultaneously (rapid titration) or only subcutaneous morphine to dose titration. The primary outcome was the safety and the number of times of rescue therapy as needed in the first 24 h. RESULTS: A total of 108 patients with moderate to severe cancer pain were included in the study. The number of times of rescue analgesics in the first 24 h significantly reduced in the rapid titration group (0.4 ± 0.48 vs. 2.3 ± 0.78, P = 0.000). No differences in the intensity of opioid-related symptoms were found between the two groups. CONCLUSIONS: Rapid titration is safe and efficient, which could significantly decrease rescue analgesics in the first 24 h and achieve better analgesic efficacy for cancer pain patients.

PALLIATIVE TREATMENT OF INTRACTABLE CANCER PAIN.

In 10% to 30% cancer-pain cases standard analgesic therapy fails to provide effective pain relief. Interventional techniques, such as peripheral nerve blocks, neuraxial analgesia along with neurolytic blocks may be used for such refractory pain. Peripheral nerve blocks can be used when pain occurs in the territory of one or more peripheral nerves, but rarely as main therapy. Neuraxial analgesia is a valid option for progressive cancer pain, and healthcare possibilities and costs call into question the utility of intrathecal infusion pumps. Neurolysis is the targeted destruction of a nerve or nerve plexus, using chemicals, radiofrequency ablation (RFA), cryoablation, and neurosurgical procedures; however, it rarely completely eliminates pain because patients frequently experience coexisting somatic and neuropathic pain as well. Complex conditions of palliative patients along with limited high-quality randomized controlled trials limit the use of interventional procedures. Even so, some cancer patients benefit from interventional procedures to achieve pain alleviation and consequently improve quality of life.

Opioid-induced constipation in patients with cancer pain in Japan (OIC-J study): a post hoc subgroup analysis of patients with lung cancer.

OBJECTIVE: To evaluate the opioid-induced constipation burden in the subgroup of patients with lung cancer who participated in the observational Opioid-Induced Constipation in Patients with Cancer Pain in Japan (OIC-J) study. METHODS: The prospective, observational study, OIC-J, included 212 patients with various tumour types, 33% of whom had lung cancer. The incidence of opioid-induced constipation was evaluated using several diagnostic criteria, as well as the physician's diagnosis and patient's subjective assessment. Following initiation of opioids, patients recorded details of bowel movements (i.e. date/time, Bristol Stool Scale form, sensations of incomplete evacuation or anorectal obstruction/blockage and degree of straining) in a diary for 2 weeks. Relationships between patient characteristics and opioid-induced constipation onset and effects of opioid-induced constipation on quality of life were explored. RESULTS: In total, 69 patients were included in this post hoc analysis. The incidence of opioid-induced constipation varied (39.1-59.1%) depending on which diagnostic criteria was used. Diagnostic criteria that included a quality component or a patient's feeling of bowel movement as an evaluation item (i.e. Rome IV, physician's diagnosis, Bowel Function Index, patient's assessment) showed higher incidences of opioid-induced constipation than recording the number of spontaneous bowel movements alone. Opioid-induced constipation occurred rapidly after initiating opioids and had a significant impact on Patient Assessment of Constipation Symptoms total score (P = 0.0031). Patient baseline characteristics did not appear to be predictive of opioid-induced constipation onset. CONCLUSIONS: In patients with lung cancer, opioid-induced constipation can occur quickly after initiating opioids and can negatively impact quality of life. Early management of opioid-induced constipation, with a focus on quality-of-life improvement and patient's assessments of bowel movements, is important for these patients.

Pain in older survivors of hematologic malignancies after blood or marrow transplantation: A BMTSS report.

BACKGROUND: Blood or marrow transplantation (BMT) is increasingly offered to older adults with hematologic malignancies; however, their risk for severe pain is poorly understood. Using the Bone Marrow Transplant Survivor Study, the current study investigated the prevalence and predictors of pain after BMT (allogeneic or autologous) as well as its association with physical performance impairments and frailty. METHODS: The cohort included 736 patients with hematologic malignancies who underwent BMT at an age ≥ 60 years at 1 of 3 transplant centers between 1974 and 2014 and survived ≥2 years after BMT; 183 unaffected siblings also participated. Study participants reported on 4 pain domains (nonminor everyday pain, moderate to severe bodily pain, prolonged pain, and moderate to extreme pain interference), and the presence of 1 or more domains was indicative of a severe and/or life-interfering pain composite variable. RESULTS: Overall, 39.4% of the BMT survivors reported severe pain with 2.6-fold greater odds of reporting pain in comparison with sibling controls. Among BMT recipients, those with less education, lower incomes, and active chronic graft-versus-host disease had higher odds of reporting pain. In multivariable analyses, BMT survivors with pain were more likely to have impaired physical performance and were more likely to meet the frailty criteria. BMT survivors reported higher use of pain medications (17.8% vs 9.3%) and opioid pain medications (6.5% vs 2.2%) in comparison with sibling controls. CONCLUSIONS: Nearly 40% of older BMT survivors who were followed for a median of 5 years after BMT reported pain, and BMT survivors had 2.6-fold higher odds of reporting severe, nonminor or life-interfering pain in comparison with siblings.

Challenges of Treating a Patient With Advanced Prostate Cancer During the COVID-19 Pandemic.

A 78-year-old man had a medical history of hypertension, atrial fibrillation, chronic kidney disease, and metastatic castration-resistant prostate cancer (CRPC). He had progressed to first-line therapy for CRPC with abiraterone plus androgen-deprivation therapy (ADT) and as second-line therapy he was being treated with docetaxel, with biochemical progression in his last prostate specific antigen measurement. He was admitted to the hospital on April 2020, in the middle of the coronavirus disease 2019 (COVID-19) pandemic, because of painful bone lesions and deterioration of renal function.

The Rate of Infectious Complications After Intrathecal Drug Delivery System Implant for Cancer-Related Pain Is Low Despite Frequent Concurrent Anticancer Treatment or Leukopenia.

BACKGROUND: The efficacy of intrathecal drug delivery (IDD) for cancer-related pain is well established. Cancer therapies are often associated with immunosuppression and increased risk of infection, and the rate of infection after intrathecal drug delivery system (IDDS) implant in cancer patients has been reported as 2.4%-6.3%. Our objective is to report on the rate of surgical site infections (SSI) in patients implanted with IDDS for cancer-related pain and to provide a data-driven discussion on the relationship between antineoplastic treatment, leukopenia, and other clinical or demographic characteristics and SSI. METHODS: Following local institutional review board approval, we conducted a retrospective chart review of IDDS implants from May 2014 through December 2018. Data collected included demographic data, health status, prophylactic antibiotic administration, surgery duration, presence of leukopenia (white blood cell [WBC] count of <4.0 K/µL) or moderate neutropenia (absolute neutrophil count [ANC] of <1000/µL) within the 30 days before IDDS implant, and details of antineoplastic treatment or systemic corticosteroid use in the perioperative period. This information was assessed in relation to SSI incidence up to 6 months following implant. RESULTS: Two hundred seventeen IDDS implants were identified. A majority of patients (79.3%) received ≥1 form of antineoplastic therapy within 30 days before or after implant, and 42.4% received multiple forms of antineoplastic therapy. Therapies included chemotherapy in 46.5%, immunotherapy in 28.6%, systemic steroids in 32.3%, and radiation therapy in 28.1%. One-quarter of patients (25.8%) were leukopenic within 30 days before implant, with 3.2% having moderate neutropenia. There were 2 infectious complications representing an infection rate of 0.9% (95% CI, 0.1%-3.3%), with limited shared characteristics between those experiencing SSI. CONCLUSIONS: SSI risk after IDDS placement for cancer pain is low, despite frequent concurrent antineoplastic therapy and leukopenia in the perioperative period. Concomitant cancer therapies should not be a barrier to the implementation of IDD for cancer pain.

Validation of the Japanese version of the barriers questionnaire II in cancer pain management: a cross-sectional study.

BACKGROUND: The Barriers Questionnaire II (BQ-II) was developed to assess barriers to effective pain management. In this study, we aimed to assess the reliability and validity of the newly developed Japanese version of the BQ-II (JBQ-II). METHODS: This study used a cross-sectional design. The study was conducted an ambulatory infusion center for cancer in a general hospital in Tokyo, Japan. Participants were 120 Japanese patients with cancer and 21 Japanese health professionals with experience in pain management. Cronbach's alpha coefficient was used to calculate reliability. Test-retest reliability was assessed with Spearman's intra-class correlation coefficient (ICC). Construct, criterion-related, and discriminant validity were assessed using information about pain management, daily life, mental health, and subjective health. RESULTS: The Cronbach's alpha was 0.90 for the JBQ-II, and all ICCs exceeded 0.70 (P < 0.01). Factor analysis showed the JBQ-II had a virtually identical structure to the BQ-II, and path analysis supported the JBQ-II constructs. The JBQ-II was weakly correlated with poor mental state (r = 0.36, P < 0.01). Patients' JBQ-II scores were significantly higher than health professionals' scores. CONCLUSION: The JBQ-II is a valid and reliable measure of patient-related barriers to pain management among Japanese adult patients with cancer.

Factors Associated with Depression in African American Patients Being Treated for Cancer Pain.

BACKGROUND: Among cancer patients in the United States, African American cancer patients have the highest mortality rate and shortest survival rate. Although depression is known as a predictor of mortality in cancer and a potential barrier to health care utilization, research on depression in African American patients is limited. Cancer pain can interfere with an individual's ability to cope with depression. AIMS: To identify factors that are associated with a positive screening of depressive symptoms assessed by the PHQ-8 in African American patients treated for cancer pain. DESIGN: Secondary data analysis of a cross-sectional study of opioid adherence. SETTING: Medical oncology, palliative care, and radiation oncology clinics in Atlanta, Georgia. PARTICIPANTS/SUBJECTS: African American patients with cancer pain in the parent study. METHODS: Independent samples t-test was used to assess variable correlations with and without depressive symptoms. Adjusted logistic regression was conducted to identify factors that were associated with presence of depressive symptoms. RESULTS: Mean patient age was 55.6 years, and nearly 38% had a PHQ-8 score of >10 indicating presence of moderate to severe depressive symptoms. Participants with depressive symptoms had significantly higher means for anxiety and pain interference with mood than those without depressive symptoms. Factors that were significantly associated with depressive symptoms were anxiety, pain interfering with mood, and lack of involvement with a religious congregation. CONCLUSIONS: The findings of this study help to identify African American cancer patients at risk for depression and demonstrates the need for increased screening for depression in this underserved population.

Neuroinflammation and central PI3K/Akt/mTOR signal pathway contribute to bone cancer pain.

BACKGROUND: Pain is one of the most common and distressing symptoms suffered by patients with progression of cancer; however, the mechanisms responsible for hyperalgesia are not well understood. Since the midbrain periaqueductal gray is an important component of the descending inhibitory pathway controlling on central pain transmission, in this study, we examined the role for pro-inflammatory cytokines of the periaqueductal gray in regulating mechanical and thermal hyperalgesia evoked by bone cancer via phosphatidylinositide 3-kinase (PI3K)-mammalian target of rapamycin (mTOR) signals. METHODS: Breast sarcocarcinoma Walker 256 cells were implanted into the tibia bone cavity of rats to induce mechanical and thermal hyperalgesia. Western blot analysis and ELISA were used to examine PI3K/protein kinase B (Akt)/mTOR and pro-inflammatory cytokine receptors and the levels of interleukin (IL)-1ß, IL-6, and tumor necrosis factor-alpha (TNF-α). RESULTS: Protein expression levels of p-PI3K/p-Akt/p-mTOR were amplified in the periaqueductal gray of bone cancer rats, and blocking PI3K-mTOR pathways in the periaqueductal gray attenuated hyperalgesia responses. In addition, IL-1ß, IL-6, and TNF-α were elevated in the periaqueductal gray of bone cancer rats, and expression of their respective receptors (namely, IL-1R, IL-6R, and tumor necrosis factor receptor (TNFR) subtype TNFR1) was upregulated. Inhibition of IL-1R, IL-6R, and TNFR1 alleviated mechanical and thermal hyperalgesia in bone cancer rats, accompanied with downregulated PI3K-mTOR. CONCLUSIONS: Our data suggest that upregulation of pro-inflammatory cytokine signal in the periaqueductal gray of cancer rats amplifies PI3K-mTOR signal in this brain region and alters the descending pathways in regulating pain transmission, and this thereby contributes to the development of bone cancer-induced pain.

Association between tobacco use, pain expression, and coping strategies among patients with advanced cancer.

BACKGROUND: The objective of the current study was to evaluate the association between tobacco use, symptom expression, and coping strategies in patients with advanced cancer. METHODS: The authors prospectively enrolled patients with advanced cancer and collected data regarding patient demographics, cancer diagnosis, morphine equivalent daily dose, cigarette smoking status using the Behavioral Risk Factor Surveillance System, symptom expression as measured by the Edmonton Symptom Assessment System, the Cut down/Annoyed/Guilty/Eye opener alcoholism questionnaire, the Screener and Opioid Assessment for Patients with Pain-short form survey, and the Brief COPE Questionnaire. RESULTS: Among 399 patients, 195 (49%) were never-smokers, 158 (40%) were former smokers, and 46 (11%) were current smokers. The most common malignancies were gastrointestinal (21%) and breast (19%). Current smokers demonstrated significantly higher pain scores at the time of consultation compared with former or never-smokers (mean 6.4 vs 5.9 vs 5.1, respectively; P = .015), demonstrated increased morphine equivalent daily dose (median 90 mg/day vs 60 mg/day vs 50 mg/day, respectively; P = .002), were more likely to screen as positive on the Cut down/Annoyed/Guilty/Eye opener questionnaire (33% vs 24% vs 8.7%, respectively; P < .0001) and were more likely to screen as positive (≥4) on the Screener and Opioid Assessment for Patients with Pain-short form survey (74% vs 13% vs 9.3%, respectively; P < .0001). Compared with former and never-smokers, current smokers were significantly more likely to cope maladaptively with substance use (P = .02), denial (P = .007), and self-blame (P < .0001). CONCLUSIONS: Among patients with advanced cancer, current and former smokers appear to be significantly more likely to have higher pain expression and thus require higher opioid doses, and to have more risk factors for using opioids in a nonprescribed manner. The results of the current study highlight the need to provide closer monitoring and increased psychosocial support for patients with cancer who smoke while receiving chronic opioid therapy.

Minimally Invasive Cordotomy for Refractory Cancer Pain: A Randomized Controlled Trial.

BACKGROUND: Up to 30% of patients with cancer continue to suffer from pain despite aggressive supportive care. The present study aimed to determine whether cordotomy can improve cancer pain refractory to interdisciplinary palliative care. MATERIALS AND METHODS: In this randomized controlled trial, we recruited patients with refractory unilateral somatic pain, defined as a pain intensity (PI) ≥4, after more than three palliative care evaluations. Patients were randomized to percutaneous computed tomography-guided cordotomy or continued interdisciplinary palliative care. The primary outcome was 33% improvement in PI at 1 week after cordotomy or study enrollment as measured by the Edmonton Symptom Assessment Scale. RESULTS: Sixteen patients were enrolled (nine female, median age 58 years). Six of seven patients (85.7%) randomized to cordotomy experienced >33% reduction in PI (median preprocedure PI = 7, range 6-10; 1 week after cordotomy median PI = 1, range 0-6; p = .022). Zero of nine patients randomized to palliative care achieved a 33% reduction in PI. Seven patients (77.8%) randomized to palliative care elected to undergo cordotomy after 1 week. All of these patients experienced >33% reduction in PI (median preprocedure PI = 8, range 4-10; 1 week after cordotomy median PI = 0, range 0-1; p = .022). No patients were withdrawn from the study because of adverse effects of the intervention. CONCLUSION: These data support the use of cordotomy for pain refractory to optimal palliative care. The findings of this study justify a large-scale randomized controlled trial of percutaneous cordotomy. IMPLICATIONS FOR PRACTICE: This prospective clinical trial was designed to determine the improvement in pain intensity in patients randomized to either undergo cordotomy or comprehensive palliative care for medically refractory cancer pain. This study shows that cordotomy is effective in reducing pain for medically refractory cancer pain, and these results can be used to design a large-scale comparative randomized controlled trial that could provide the evidence needed to include cordotomy as a treatment modality in the guidelines for cancer pain management.

Prevalence, characteristics, and treatment of fatigue in oncological cancer patients in Italy: a cross-sectional study of the Italian Network for Supportive Care in Cancer (NICSO).

BACKGROUND: Fatigue is one of the most distressing symptoms of cancer patients. Its characteristics and impact on quality of life have not been fully explored and treatment of cancer-related fatigue in Italian oncological centers has not been codified. METHODS: A cross-sectional study was carried out on all patients attending for any reason the 24 participating centers in two non-consecutive days. Patients with fatigue filled out the Brief Fatigue Inventory (BFI) questionnaire and reported any pharmacological or non-pharmacological treatment for fatigue. RESULTS: From October 2014 to May 2015, 1394 cancer patients agreed to participate in the study. Fatigue was referred by 866 (62.1%) of patients; its duration was > 4 months in 441 patients (50.9%). In the investigators' opinion, the most important (probable or almost sure) determinants of fatigue were reduced physical activity (271 patients), anxiety (149), pain (131), insomnia (125), anemia (123), and depression (123). Fatigue of moderate/severe intensity was reported by 43%/29.2% of patients, while usual fatigue in the last 24 h by 45%/33.1%, and the worst fatigue in the last 24 h by 33%/54.8%, respectively. Concerning the impact on quality of life, fatigue interfered moderately/severely with general activity in 30.8%/38.6% of patients, with mood in 26.1%/32.8%, with the ability to work in 27.9%/35.6%, with normal work in 26.7%/38.9%, with relationships with others in 21%/23.4% and with the ability to amuse themselves in 22.2%/33.1%. Only 117/866 patients (13.5%) received a pharmacological treatment represented by a corticosteroid in 101 patients (86.3%) while 188 patients (21.7%) received a non-pharmacological treatment such as physical exercise (120 patients, 63.8%) and various alimentary supplements (52 patients, 27.6%). CONCLUSIONS: Cancer-related fatigue is frequently reported by oncological patients; its intensity and impact on quality of life is relevant.

Breast Cancer Collaborative Registry informs understanding of factors predicting sleep quality.

SIGNIFICANCE: Poor sleep quality is a common and persistent problem reported by women with breast cancer (BC). Empirical evidence identifies many risk factors for self-reported sleep deficiency, but inconsistencies limit translation to practice. PURPOSE: To increase understanding of risk factors predicting self-reported poor sleep quality in women with BC who completed the Breast Cancer Collaborative Registry (BCCR) questionnaire. METHODS: This cross-sectional study recruited women with a first diagnosis of BC (n = 1302) at five sites in Nebraska and South Dakota. Women completed the BCCR that includes numerous variables as well as the Pittsburgh Sleep Quality Index (PSQI) and SF36v2 (n = 1260). Descriptive statistics and non-parametric correlations were used to determine associations and create predictive models of sleep quality with BCCR variables and SF36v2 subscales. RESULTS: Most women were white (93.7%) and married (71.5%); mean age was 60.1 (21-90) years. Poor sleep was self-reported by 53% of women. Seven variables were highly associated with sleep quality (p ≤ 0.001). The first model found younger age, lower physical activity, and higher fatigue were the strongest combined and independent variables predicting poor sleep quality (F = 23.0 (p < .001), R2 = 0.103). Participants self-reported lower health status on most SF36v2 subscales [Z = 44.9 (11.6) to 49.1 (10.1)]. A second model found that all subscales were predictors of poor sleep; vitality, mental health, bodily pain, and general health were the strongest predictors (F = 101.3 (p < .001), R2 = 0.26). CONCLUSIONS: Results confirm previously identified risk factors and reveal inconsistencies in other variables. Clinicians need to routinely screen for the identified risk factors of self-reported poor sleep quality.
