Effect of baseline cancer pain on the efficacy of immunotherapy in lung cancer patients. J Thorac Dis 2023; 15:4314-4323. [PMID: 37691656 PMCID: PMC10482640 DOI: 10.21037/jtd-23-375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 07/07/2023] [Indexed: 09/12/2023]
Abstract
Background Cancer pain is a common symptom in cancer patients. However, few reports have evaluated the effect of baseline cancer pain on the efficacy of immunotherapy in lung cancer patients. The aim of this retrospective study is to reveal the effect of baseline cancer pain on the prognosis of lung cancer patients receiving immunotherapy. Methods We retrospectively reviewed the medical records of lung cancer patients who received immunotherapy at Zhejiang Cancer Hospital and were included 280 patients with or without baseline cancer pain. Propensity score matching (PSM) was used to minimize potential selection bias. Progression-free survival (PFS) and overall survival (OS) were assessed using Kaplan-Meier estimation and log-rank tests. Cox proportional hazard regression analysis was performed to identify factors associated with survival independence. Results The median PFS and OS of the patients with baseline cancer pain were significantly shorter than that of patients without baseline cancer pain (PFS: 3.1 vs. 6.5 months, P=0.001; OS: 16.5 vs. 31.2 months, P<0.001). PSM also included 27 patients with or without breakthrough pain. Patients with breakthrough pain had significantly shorter median PFS and OS than those without breakthrough pain (PFS: 1.9 vs. 4.2 months, P=0.001; OS: 9.9 vs. 18.7 months, P=0.012). Cox analysis results implicated breakthrough pain as an independent prognostic factor for immunotherapy. Conclusions Baseline cancer pain is a negative prognostic factor for lung cancer patients receiving immunotherapy. Patients with baseline cancer pain may have a worse survival prognosis if they develop breakthrough pain.

A retrospective study of the efficacy and safety of naldemedine for opioid-induced constipation in thoracic cancer patients. Thorac Cancer 2022; 13:2301-2308. [PMID: 35790500 PMCID: PMC9376157 DOI: 10.1111/1759-7714.14557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 06/07/2022] [Accepted: 06/10/2022] [Indexed: 12/01/2022] Open
Abstract
Background We conducted a multicenter, retrospective study on the efficacy and safety of naldemedine in thoracic cancer patients using opioids in clinical practice. Methods We retrospectively evaluated thoracic cancer patients treated with naldemedine at 10 institutions in Japan. Clinical data of patients administered naldemedine between June 2017 and August 2019 were extracted from electronic medical records. Inclusion criteria were as follows: (i) patients hospitalized for at least seven days before and after naldemedine administration, and (ii) those whose frequency of defecation was entered in the medical records. Results Forty patients were analyzed, and defecation frequency was observed for at least seven days before and after naldemedine administration. The response rate was 65.0% (95% CI: 50.2%–79.7%). The number of defecations increased significantly after naldemedine administration in the overall population, as well as among only those who defecated <3 times/week before naldemedine administration, and those that were administered ≥30 mg/day of morphine equivalent. Diarrhea was the most common adverse event in all grades, occurring in 11 patients (27.5%), of which 9 (81.8%) were grade 1 or 2. None of the patients experienced grade 4 or higher adverse events. Conclusion The efficacy and safety of naldemedine for thoracic cancer patients in clinical practice were comparable with those of prospective studies, which suggest that naldemedine may be effective and feasible for most thoracic cancer patients.

Abstract
This phase III multicenter randomized double-blind placebo-controlled comparative study evaluated the efficacy and safety of diclofenac sodium patches for the treatment of cancer pain. The study consisted of a 2-week to 4-week open-label dose-titration phase and a 4-week double-blind phase. In the double-blind phase, patients who were expected to continue treatment of cancer pain with nonopioid analgesics alone were randomized to the diclofenac sodium patch or placebo group. Once-daily diclofenac sodium patches were started at 150 mg/day (2 patches) and could be increased up to 225 mg/day (3 patches). The primary efficacy endpoint was the time to insufficient analgesic response. Statistical analysis of the double-blind phase included data from 120 patients of the diclofenac sodium patch group and 118 patients of the placebo group. Time to insufficient analgesic response was significantly longer with diclofenac sodium patches than with placebo (P = 0.0016). The hazard ratio for insufficient response for diclofenac sodium patch vs placebo was 0.459 (95% confidence interval, 0.275-0.768). Regarding sleep quality during the double-blind phase, the proportion of patients with “very good sleep” or “good sleep” in the diclofenac sodium patch and placebo groups was 90.8% and 88.1% at the start of the double-blind phase and 81.4% and 78.6% at the final assessment, respectively. The incidence of adverse events was 60.8% (73/120) in the diclofenac sodium patch group and 60.2% (71/118) in the placebo group. Once-daily diclofenac sodium patches are effective in treating cancer pain and are well tolerated.

A living systematic review to assess the analgesic undertreatment in cancer patients. Pain Pract 2022; 22:487-496. [PMID: 35014151 DOI: 10.1111/papr.13098] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/15/2021] [Accepted: 01/03/2022] [Indexed: 11/28/2022]
Abstract
This living, systematic review aims to provide an updated summary of the available evidence on pain undertreatment prevalence in patients with cancer; correlations with some potential determinants and confounders were also carried out. We updated a systematic review published in 2014, including observational and experimental studies reporting the use of the pain management index (PMI) in adults with cancer and pain, from 2014 to 2020. We conducted searches in PubMed/MEDLINE, Embase, and Google Scholar. We performed univariate and multivariable regression analyses to describe the relationship between PMI and a list of potential explanatory variables. Twenty new papers were identified, yielding a total sample size of 66 studies. The proportion of patients classified as undertreated according to the year of study publication shows a higher decrease from 1994 to 2013 (-13% as relative change) than the most recent years 2014-2020 (-11%). The quality of the included studies has increased over the years (from 80% to 93%). At the multivariable analysis, a statistically significant relationship was confirmed between undertreatment and the year of the publication of the study and with a low-medium economic level of the countries where the studies were conducted. Despite the improvement when compared to the period 1994-2000,-still about 40% of the cases identified received an analgesic treatment inadequate to the intensity of pain, according to the PMI. Despite its intrinsic limitations, PMI continues to be widely used and it could allow a continuous monitoring of pain management across a different mix of studies and patients.

National Study of Pain Medicine Access Among Māori and Non-Māori Patients With Lung Cancer in New Zealand. JCO Glob Oncol 2021; 7:1276-1285. [PMID: 34383597 PMCID: PMC8389912 DOI: 10.1200/go.21.00141] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
PURPOSE Pain is among the most common and consequential symptoms of cancer, particularly in the context of lung cancer. Māori have extremely high rates of lung cancer, and there is evidence that Māori patients with lung cancer are less likely to receive curative treatment and more likely to receive palliative treatment and to wait longer for their treatment than non-Māori New Zealanders. The extent to which Māori patients with lung cancer are also less likely to have access to pain medicines as part of their supportive care remains unclear. METHODS Using national-level Cancer Registry and linked health records, we describe access to subsidized pain medicines among patients with lung cancer diagnosed over the decade spanning 2007-2016 and compare access between Māori and non-Māori patients. Descriptive and logistic regression methods were used to compare access between ethnic groups. RESULTS We observed that the majority of patients with lung cancer are accessing some form of pain medicine and there do not appear to be strong differences between Māori and non-Māori in terms of overall access or the type of pain medicine dispensed. However, Māori patients appeared more likely than non-Māori to first access pain medicines within 2 weeks before their death and commensurately less likely to access them more than 24 weeks before death. CONCLUSION Given the plausibility that there are differences in first access to pain medicines (particularly opioid medicines) among Māori approaching end of life, further investigation of the factors contributing to this disparity is required.

Abstract
Purpose To further evaluate the efficacy and safety of computed tomography (CT)-guided iodine 125 (125I) brachytherapy to treat locally advanced non-small cell lung cancer (NSCLC) after progression of concurrent radiochemotherapy (CCRT). Methods This study obtained written consent from all patients and was approved by our institution. From January 2006 to June 2018, 210 NSCLC patients (progression of first-line CCRT) were retrospectively recruited and then divided into two groups. A total of 116 patients were given CT-guided 125I brachytherapy and second-line chemotherapy (group A), and 94 were treated with second-line chemotherapy alone (group B). Results In group A, local response rate (LRR) within 3 years was significantly better (P<0.05). Mean survival time [progression-free survival time (PFST) and overall survival (OS)] was 15.1±1.4 months and 21.2±1.6 months in group A compared with 10.0±1.4 months and 16.2±1.7 months in group B (PFST: P<0.01, HR=1.472, 95% CI 1.097–1.975; OS: P = 0.036, HR=1.342, 95% CI 1.005–1.791). Tumor size and No. of first cycle chemotherapy were independent factors that affected survival, ≤3cm largest tumor diameter and more than 4 first cycles of chemotherapy showed longer PFST and OS (P<0.05). Tumor-related clinical symptoms were relieved in group A (P<0.01). No serious complications occurred in the two groups. Conclusion 125I brachytherapy is effective and safe in locally advanced NSCLC after progression of CCRT.

Abstract
AbstractThere is limited data on management of metastatic nonsmall cell lung cancer (NSCLC) in the elderly population due to lack of representation of this subset in clinical trials. The projected representation of elderly population of patients globally is expected to rise significantly in the years to come. It is imperative to understand the specific challenges and opportunities in management of elderly with NSCLC. Even in the elderly, the medical management of advanced NSCLC begins with driver mutation testing on lung biopsy. Once the patient is classified as driver mutation positive or negative, they can either be treated with a single-agent-targeted therapy or with immunotherapy and chemotherapy or after programmed death ligand 1 (PDL-1) assessment, with immunotherapy alone. After starting the appropriate therapy, the disease needs to be monitored at every 3 months with reassessment scans. Treatment in elderly should be designed as per their functional and not chronological age, and geriatric assessment scales should be utilized wherever possible to understand the functional age of the patient.

Abstract
Aim: To describe pain management regulations, prevalence of pain and pain management practices in a Zimbabwean setting. Materials & methods: A multi-methods approach was used, consisting of: policy and guideline review; review of 410 cervical cancer patient records for pain symptoms and pain management data; and semistructured interviews with oncology healthcare practitioners. Results: We found a lack of policies that are specific for cervical cancer pain management. Although prevalence of pain was 68% (n = 278), only 42% of the patient records indicated pain drugs had been prescribed. Barriers to pain management included inadequate use of pain assessment tools, inaccessibility of key drugs and limited capacity. Conclusion: Cancer pain management in Zimbabwe can be improved by tailoring assessment protocols, improving drug accessibility and strengthening healthcare systems.

Opioid-induced constipation in patients with cancer pain in Japan (OIC-J study): a post hoc subgroup analysis of patients with lung cancer. Jpn J Clin Oncol 2021; 51:444-450. [PMID: 33157554 PMCID: PMC7937418 DOI: 10.1093/jjco/hyaa186] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 09/21/2020] [Indexed: 11/13/2022] Open
Abstract
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.

Abstract
Background: The presence of lung cancer is almost always associated with pain, a symptom that causes severe distress in patients. Although many pharmacological methods are available to manage pain in this oncologic population, the medications often cause undesirable sideeffects and inadequate relief. Nonpharmacological interventions can be used as adjuvants to pharmacological interventions in reducing pain and increasing quality of life. Objectives: The purpose of this review is to compare the efficacy of nonpharmacological interventions in reducing pain in lung cancer patients. Materials and Methods: This is a systematic review study guided by the Preferred Reporting Items of Systematic reviews and Meta-Analysis Protocol. Interventions identified in the present systematic review have been categorized as physical treatment, technologybased, cognitive behavioral, coping, and coaching. Results: Results indicate that the nonpharmacological interventions such as physical treatment interventions, selfmanagement and coaching interventions, cognitive behavioral interventions, and technologybased interventions or coping skills interventions had limited and shortterm effects on alleviating pain among the patients. However, previous studies have provided limited evidence regarding nonpharmacologic therapy due to the lack of a comparison group, small sample sizes, and lack of longterm followup periods to determine whether sustained effects are feasible. Conclusion: Healthcare professionals should consider additional research on the added advantage of utilizing the nonpharmacological interventions as an adjunct option while managing pain in lung cancer patients.

Abstract
Background With the recent advancement in medicine there has been a great emphasis on the management of chronic pain which remains as one of the major contributing factors for functional limitation in patients as well as a financial burden on healthcare. Newer treatment modalities are aimed at terminating the vicious pain cycles and in this regard peripheral nerve blocks have proven to be very effective. Objectives The aim of this study is to evaluate the effectiveness of interventions for both cancer and non-cancer patients by objective assessment of the patients before and after the procedure. Materials and methods The study included 252 patients who underwent nerve block procedures in Shaukat Khanum Memorial Cancer Hospital from December 2016 to December 2018. The patients were evaluated using numerical rating scale (NRS) for pain, reduction in analgesic doses and patient satisfaction after one and four weeks post procedure. The data was analyzed using mean values and calculating percentages. Results In cancer group, 168 patients were included; mean age 50.49 ± 15.39 with 46.43% females and 53.57% males, the average pain score was 2.62 ± 1.87 post procedure compared with 6.30 ± 1.87 post procedure. 48.21% of the patients reported a reduction in analgesia while 51.79% of the patients kept on using the same analgesics doses. 74.40% of the patients were satisfied and 25.60% patients remained unsatisfied after one week whereas 66.07% were satisfied, 23.81% were not satisfied and 10.12% loss to follow up after four weeks. In non-cancer group 84 patients were included; mean age 56.49 ± 15.79 with 41.67% females and 58.33% males, the average pain score before intervention was 5.99 ± 1.21 and after intervention it was 2.43 ± 1.62. In 73.81% non-cancer patients the analgesics doses were reduced and 70.24% patients were satisfied while 29.76% were unsatisfied after one week. After four weeks 55.95% were satisfied, 22.62% were not satisfied and 21.43% loss to follow up. Conclusion The study showed decrease in pain scores in both group of patients and the importance of nerve blocks as an effective method for chronic pain management. The reduction in the use of other analgesics was also commendable in both the groups.

Abstract
CONTEXT Chronic pain (CP) is a major concern in cancer survivors. Often under-reported by patients, it is both underassessed and undertreated by care providers. OBJECTIVES To assess CP prevalence and related treatment in cancer survivors five years after diagnosis and to identify factors associated with prescribing opioids among survivors with CP, focusing on access to palliative care (PC). METHODS In 2015-2016, we interviewed 4174 French patients diagnosed with cancer five years previously. Combining patient-reported and clinical-reported outcomes together with medicoadministrative data, we studied factors associated with Step II and Step III opioid prescriptions in cancer survivors with CP. We performed multinomial logistic regression adjusting for various covariates, including self-reported health status variables and inpatient PC. RESULTS Five years after cancer diagnosis, 63.5% of the respondents reported current CP (i.e., pain lasting three months or more). Of these, 64.6% and 14.4% were prescribed at least one Step II or Step III opioid, respectively. Only 1.9% had had inpatient PC since diagnosis. After adjustment for age, gender, clinical and self-reported variables, we found that the latter were more likely to receive Step III opioids (adjusted relative risk ratio 5.33; 95% CI 1.15, 24.58). CONCLUSION This study showed a high prevalence of CP five years after cancer diagnosis. Step III opioids were underprescribed but positively associated with inpatient PC. PC access in France remains limited, especially among cancer survivors. Integrating PC in oncology is essential to provide the best cancer-related symptoms management.

Abstract
Background Inadequate pain management is highly prevalent and is associated with significant costs and socioeconomic problems, which can lead to disparities in patient care. Specific groups are at higher risk of this problem. A few studies have evaluated the predictive risk factors of inadequate pain management. Objectives This study evaluated the prevalence and predictive risk factors of inadequate pain management at the primary and secondary care centers with large sample size. Methods Patients who had been managed in primary and secondary care clinics were asked to report their personal characteristics, pain intensity, pain duration, and analgesics they were receiving in their first visit at our pain clinic. Zelman pain management index was calculated for each patient by analgesic potency minus mean pain intensity. The negative index showed incongruence between pain intensity and analgesic potency score (pain stronger than medication), indicating inadequate pain management. Results A negative pain management index was reported in 77% of the 511 recruited patients. Patients with more severe pain were more likely to experience inadequate pain management. A logistic model demonstrated women, people aged 45 - 65 years, illiterates, and obese patients were at higher risks of inadequate pain management. The pain management index was affected by sex and education (via higher pain intensities) and by age and BMI (via lower analgesic potency). Conclusions Age, sex, education, and BMI are predictive risk factors of inadequate pain management as a prevalent problem in chronic pain patients.

Abstract
Aim: Chronic pain is common in terminally ill patients with cancer and affects their quality of life. In this study, we wanted to evaluate pain severity and the adequacy of prescribed analgesics in terminally ill patients with cancer in North Palestine. Methods: We conducted a cross-sectional descriptive study in North Palestine on 77 terminally ill patients with cancer. Pain experience was evaluated with Brief Pain Inventory-Short Form (BPI-SF). Pain management index (PMI) was calculated to determine the adequacy of interventions. The relationships between adequacy of pain management and socioeconomic and clinical factors were analyzed by the covariance method. Statistical analyses were performed using Statistical Package for the Social Sciences (SPSS version 15.0 [SPSS Inc., Chicago, USA]). Results: Fifty-nine patients (76.6%) reported moderate-to-severe pain. According to the PMI, only 64.9% of the patients received adequate pain management. Thirty-five patients (45%) wanted additional treatment or an increase in the dose of pain medications. Although men and women reported similar pain severities, women were more likely to be inadequately treated (P = 0.027). Pain severity was significantly less in patients who received health-care services at least once in the last month before the interview, compared to those without recent access to health care (P = 0.024). Conclusion: There is substantial inadequacy in pain management in patients with cancer. The BPI-SF should be routinely used to evaluate pain severity, and analgesics should be prescribed equitably without discrimination with regard to gender and socioeconomic status of patients.

Abstract
Purpose To identify patterns of analgesic prescription and to explore patient-reported pain intensity, sleep disturbance, and quality of life among cancer patients with pain in Southeast Asia (SEA). Methods This cross-sectional observational study included 465 adult outpatients prescribed analgesics for cancer pain for 1 month or longer at 22 sites in Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Data on analgesic prescription and cancer characteristics were extracted from medical records. Pain intensity, sleep disturbance, and quality of life measures were recorded via questionnaires. Results Most patients (84.4%) had stage III or IV cancer. A total of 419 patients (90.7%) were prescribed opioids; of these, 42.2% received only weak opioids, whereas 57.8% received at least one strong opioid. The mean worst pain intensity during the past 24 hours was 4.76 (standard deviation [SD], 2.47) on a scale of 0 (no pain) to 10 (worst possible pain); the mean current pain intensity was 4.10 (SD, 2.61). More than half of patients (54.8%) reported sleep disturbance caused by pain in the past 7 days. The majority of patients reported problems with pain/discomfort (82.3%), usual activities (65.8%), mobility (58.2%), and anxiety/depression (56.3%). The median daily dose prescribed in oral morphine equivalents was 30 mg for both morphine and tramadol. Conclusion Despite unrelieved pain, sleep disturbance, and issues with quality of life, a notable proportion of patients were prescribed only weak opioids, and opioid doses prescribed were generally low. Efforts focused on encouragement of prescriptions with analgesic strength and/or doses proportional to the pain management needs of patients are vital to improve the status of cancer pain management in the region.

Dimensionality and Measurement Invariance of the Italian Version of the EORTC QLQ-C30 in Postoperative Lung Cancer Patients. Front Psychol 2019; 10:2147. [PMID: 31649573 PMCID: PMC6792474 DOI: 10.3389/fpsyg.2019.02147] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Accepted: 09/05/2019] [Indexed: 12/20/2022] Open
Abstract
Background This study aims to validate and evaluate the psychometric properties and measurement invariance of the Italian version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30), which is a measure of quality of life (QoL) for lung cancer patients after surgery. Methods A total of 167 lung cancer patients completed the Italian version of the EORTC QLQ-C30 questionnaire at 30 days after they received a lobectomy. The factor structure of this scale was assessed by performing confirmatory factor analysis (CFA). Measurement invariance was evaluated by considering differential item functioning (DIF) due to age, gender, and type of surgery (i.e., robot- or not robot-assisted). Results The CFA demonstrated the validity of the factor structure of the EORTC QLQ-C30 in assessing overall health and eight distinct subscales of adverse events and functioning. Moreover, the results highlighted a minimal DIF with only trivial consequences on measurement invariance. Specifically, the DIF did not affect the mean differences of latent scores of QoL between patients undergoing robot-assisted surgery or traditional surgery. Conclusion These findings supported the validity and suitability of the EORTC QLQ-C30 for the assessment of QoL in lung cancer patients of diverse ages and genders undergoing lobectomy with or without robot-assisted surgery.

Abstract
Cancer is an increasing public health burden for Ethiopia. Pain is among the most common symptoms in patients with cancer. Hence, we aimed to assess cancer pain prevalence, cancer pain interference, and adequacy of cancer pain treatment in the oncology ward of an Ethiopian teaching hospital. Of 83 patients, total of 76 (91.6%) cancer patients experienced pain with varying degree of severity, and 7 (8.4%) patients experienced severe pain. Of the 76 cancer patients with pain, 68 (89.2%) experienced pain interference with their daily activities. Fifty-four (65%) patients were receiving inadequate cancer pain treatment with negative Pain Management Index. Therefore, it is vital to anticipate and assess pain of the cancer patients as routine clinical practice, to optimize analgesic therapy, and to identify and overcome barriers to adequate pain management.

Abstract
CONTEXT Chronic pain needs to be evaluated with a standard instrument. The Brief Pain Inventory (BPI) is a pain assessment tool that has been validated in many languages. OBJECTIVES The aim of the present study was to develop the Persian version of the Brief Pain Inventory (BPI-P) and also to evaluate the psychometric properties of the BPI-P in the Iranian population. METHODS The BPI-P was translated from the original version of BPI using standard procedure. The Persian version of the BPI and 12-item Short-Form Health Survey (SF-12) were completed by 201 patients with chronic pain who were referred to a tertiary pain care clinic from 2013 to 2015. The performance status of the patients was evaluated by physicians using Eastern Cooperative Oncology Group performance test. RESULTS Factor analysis of the BPI-P identified two scales: pain intensity and pain interference with life. These two factors explained 68.4% of the variance. Coefficient alpha values for BPI-P items ranging from 0.87 to 0.91 showed good internal consistency of the factors. The high intraclass correlation coefficients for the items of the questionnaire confirmed the test-retest reliability for the BPI-P. Patients with higher scores in Eastern Cooperative Oncology Group performance test reported higher levels of pain intensity and pain interference with life. Pain intensity in BPI-P correlated with physical functioning, bodily pain, mental health, and vitality of the SF-12 questionnaire, whereas pain interference was associated with general health, bodily pain, mental health, vitality, and social functioning. CONCLUSION The present study demonstrated that the Persian version of the BPI could be a valid and reliable instrument for pain assessment in Persian-speaking patients.

Abstract
Zoledronic acid is an established agent used in the management of metastatic bone disease. The administration of zoledronic acid improves overall survival (OS) of lung cancer patients with bone metastases receiving chemotherapy. However, it is currently unknown whether zoledronic acid-induced fever is associated with OS. The purpose of this study was to examine the association between zoledronic acid-induced fever and prognosis in lung cancer patients with bone metastases. We retrospectively analyzed 98 lung cancer patients with bone metastases who had received zoledronic acid. The end point outcome measure was OS. Multivariate analyses were used to estimate the hazard ratio (HR) for OS due to fever after adjusting for covariates. In multivariate analysis, white blood cell (WBC) count, lactate dehydrogenase (LDH) level, fever, chemotherapy, and hypercalcemia were independent prognostic factors, with HRs of 2.834 for WBC count (<10 × 103/μL vs. ≥10 × 103/μL, p < 0.001), 3.044 for LDH level (<250 vs. ≥250 IU/L, p < 0.001), 0.603 for fever (<37.0 vs. ≥37.0°C, p = 0.039), 0.481 for chemotherapy (chemotherapy not administered vs. administered, p = 0.006), and 2.453 for hypercalcemia (<11.0 vs. ≥11.0 mg/dL, p = 0.001). Zoledronic acid-induced fever was the most important prognostic factor in this cohort of lung cancer patients with bone metastases.

Abstract
BACKGROUND Pain is a highly prevalent and distressing symptom in patients with cancer but at the same time inadequately treated in many of these patients. The major reason for such imbalance is inappropriate pain assessment. To overcome such a barrier, the use of a valid and reliable pain assessment tool in the language the patient understands is invaluable. Unfortunately, until now, no such standardized tool has been utilized in Ethiopian patients with cancer for both clinical and research purposes. OBJECTIVES This study tried to validate the Amharic language version of the Brief Pain Inventory (BPI-Am) and evaluate the adequacy of cancer pain management using the Pain Management Index (PMI). METHODS A standard forward/backward translation technique was used for translating the BPI from its original English version into Amharic (BPI-Am). The BPI-Am was administered to 291 Ethiopian patients with cancer who fulfilled the inclusion criteria. Factor analysis was used to identify the underlying constructs of the tool. Mean comparison was used to confirm the sensitivity of the BPI-Am to known patient groups that differed based on their performance status. Cronbach's α and intraclass correlation coefficients, respectively, were used to assure internal consistency and test-retest reliability of the BPI-Am. The PMI was calculated to identify the level of inadequate pain management in the current sample. Stepwise logistic regression was used to identify potential predictors of inadequate pain management. RESULTS Factor analysis yielded 3 factors-pain severity, physical activity interference, and psychosocial interference-with Cronbach's α coefficients of 0.85, 0.87, and 0.77, respectively. The BPI-Am showed the capacity to detect higher mean pain severity and mean pain interference scores in patients with poor performance status as compared with those having a good performance status (P < 0.001). Intraclass correlation coefficients for test-retest reliability were 0.75 and 0.78 for the pain severity and pain interference composite scores, respectively. Sixty-seven percent of patients in the current sample were inadequately treated for their pain according to the PMI. Good performance status (odds ratio [OR] = 2.9, P < 0.01), absence of cancer-related complications (OR = 2.1, P < 0.05), and being unemployed (OR = 2.6, P < 0.01) were identified as predictors of inadequate pain management. CONCLUSION The BPI-Am is a valid and reliable tool for use in Ethiopian patients with cancer. The inadequacy of cancer pain management in these groups of patients is high, which calls for needed attention.

Abstract
OBJECTIVE To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms. SUBJECTS AND METHODS This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ2, Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis. RESULTS The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled. CONCLUSION In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey.

Abstract
The objective of this descriptive study is to explore the relationships between pain, sleep disturbance, and quality of life among Palestinian patients diagnosed with cancer in the West Bank. A cross-sectional, descriptive-correlational design was used to collect data from 184 patients with cancer. The quality of life questionnaire, visual analogue pain scale, and physical health status were used in data collection. The results showed that the mean score for pain was 5, the best functioning was for cognitive scale (M = 75, SD = 29), the worst symptoms experienced by patients was appetite loss (M = 47, SD = 35), a moderate global health status (M = 53, SD = 27), and the mean for sleep disturbance was 43 (SD = 35). Pain and sleep disturbance showed high negative correlations with functional scales of quality of life and positive with symptom scales. The findings showed that the co-occurrence of pain and sleep disturbance was negatively correlated with quality of life (QoL) and positively with symptom scales. The regression analysis revealed that pain and sleep disturbance accounted for a significant proportion of variance in the QoL (p < 0.001), and the highest proportion was in predicting global health status (41.9 %). The findings of this study give evidence about the importance of assessing pain and sleep quality among Palestinian patients with cancer.

Abstract
BACKGROUND Bone is one of the most common sites of metastases, with bone metastases-related pain representing a significant source of morbidity among patients with cancer. Magnetic resonance-guided focused ultrasound is a noninvasive, outpatient modality with the potential for treating painful bone metastases. The aim of this study is to report our initial experience with magnetic resonance-guided focused ultrasound in the treatment of bone metastases and our preliminary analysis of urinary cytokine levels after therapy. METHODS This was a single-center pilot study of 10 patients with metastatic cancer to investigate the feasibility of magnetic resonance-guided focused ultrasound for primary pain control in device-accessible skeletal metastases. Treatments were performed on a clinical magnetic resonance-guided focused ultrasound system using a volumetric ablation technique. Primary efficacy was assessed using Brief Pain Inventory scores and morphine equivalent daily dose intake at 3 time points: before, day 14, and day 30 after the magnetic resonance-guided focused ultrasound treatment. Urine cytokines were measured 3 days before treatment and 2 days after the treatment. RESULTS Of the 10 patients, 8 were followed up 14 days and 6 were followed up 30 days after the treatment. At day 14, 3 patients (37.5%) exhibited partial pain response and 4 patients (50%) exhibited an indeterminate response, and at day 30 after the treatment, 5 patients (83%) exhibited partial pain response. No treatment-related adverse events were recorded. Of the urine cytokines measured, only Transforming growth factor alpha (TGFα) demonstrated an overall decrease, with a trend toward statistical significance ( P = .078). CONCLUSION Our study corroborates magnetic resonance-guided focused ultrasound as a feasible and safe modality as a primary, palliative treatment for painful bone metastases and contributes to the limited body of literature using magnetic resonance-guided focused ultrasound for this clinical indication.

Abstract
BACKGROUND In the outpatient oncology clinic, pain management is often inadequate. Incorporating a systematic pain management program into visits is likely to improve this. We implemented an integrated program, including a structured pain assessment, pain treatment protocol and patient education module. In the present study, we investigated whether this intervention improved pain control. PATIENTS AND METHODS At seven oncology outpatient clinics, patients were asked to register their pain intensity on a touch screen computer. These scores were made available into their electronic medical records. Additionally, a hospital-wide treatment protocol for cancer-related pain and a patient education module were developed. A data warehouse system enabled us to extract patient data from the electronic medical record anonymously and to use them for analysis. The primary outcome of the study was the percentage of patients with moderate to severe pain [current pain (CPI), NRS > 4] measured during 2 weeks at the start and 6 months after implementation. As secondary outcomes, we studied the percentage of pain registrations in specific patient groups and the percentage of patients treated with a curative and a palliative intention with (moderate-severe) pain. Differences were tested with the χ(2) test. RESULTS During the first 6 months, 3407 of the 4345 patients (78%) registered their pain intensity on the touch screen computer. The percentage of patients with moderate to severe CPI decreased 32% (P = 0.021): from 12.5% at start to 8.5% after 6 months. More patients in the palliative phase than in the curative phase of their disease registered their pain intensity (82% versus 75%, respectively, P < 0.005), and more patients in the palliative phase experienced moderate to severe pain (23% versus 14%, respectively, P < 0.001). CONCLUSION Pain registration by patients themselves is feasible, provides insight into patients' pain intensity and may improve pain control in outpatients with cancer-related pain. CLINICAL TRIAL NUMBER Because this is an innovation project and not a primary research project, it has no clinical trial number. The protocol and all materials involved were approved by the Institutional Review Board of the Erasmus MC (MEC-2009-324).

Abstract
Lung cancer is the leading cause of death due to malignancy. Although lung cancer mortality has been decreasing in recent years, it remains substantially higher than other causes of cancer death. Median survival for patients with locally advanced non-small cell lung cancer, defined as lung cancer involving regional lymph nodes, is estimated to be approximately 10 to 17 months, and median survival for patients with metastatic disease is only 6 to 9 months. In addition, patients with advanced lung cancer often experience debilitating symptoms and poor quality of life. Pain, dyspnea, and fatigue are most frequently reported and affect at least 65% of patients with advanced lung cancer. Given this burden of symptoms and high mortality, patients and their families facing a diagnosis of advanced lung cancer are in need of support. Palliative care, with its focus on addressing the emotional, physical, and spiritual sources of suffering utilizing the expertise of an interdisciplinary team, can provide this comprehensive support. This review describes the role of supportive and palliative care integrated into the treatment of patients with a diagnosis of advanced lung cancer with sections focused on the evaluation and treatment of pain and dyspnea, approaches to challenging communication tasks, and the support of caregivers who care for patients with advanced lung cancer.

Abstract
PURPOSE People with advanced cancer experience different sequelae which have unique effects on quality of life (QOL). The patient-generated index (PGI) is a personalized measure that allows patients to nominate, rate, and value areas that have the most impact on QOL. Fatigue, pain, and aspects of physical function are among the top 10 areas with QOL impact. An area of validation that is lacking for the PGI is the extent to which spontaneously nominated areas of QOL that patients are concerned with, agree with ratings obtained from standard patient reported outcomes (PROs). METHODS Data from 192 patients were used to compare ratings on fatigue, pain, and physical function obtained from PGI to those from standard outcome measures. RESULTS Within one severity rating, agreement ranged from 32.1 to 76.9 % within the fatigue domain, 34.2 to 95.24 % for pain, and between 84.2 and 94.7 % for physical function. Of the 10 items where the PGI had the highest agreement, 7 came from the RAND-36. At the domain level, people nominating an area scored in the more impaired range on standard measures than people who did not. CONCLUSION PGI gives comparable information as do standard measures. IMPLICATIONS FOR CANCER PGI provides important information to guide clinical care of the patient and also produces a legitimate total score suitable for research.

Abstract
PURPOSE The WHO guidelines on cancer pain management recommend a sequential three-step analgesic ladder. However, conclusive data are lacking as to whether moderate pain should be treated with either step II weak opioids or low-dose step III strong opioids. PATIENTS AND METHODS In a multicenter, 28-day, open-label randomized controlled study, adults with moderate cancer pain were assigned to receive either a weak opioid or low-dose morphine. The primary outcome was the number of responder patients, defined as patients with a 20% reduction in pain intensity on the numerical rating scale. RESULTS A total of 240 patients with cancer (118 in the low-dose morphine and 122 in the weak-opioid group) were included in the study. The primary outcome occurred in 88.2% of the low-dose morphine and in 57.7% of the weak-opioid group (odds risk, 6.18; 95% CI, 3.12 to 12.24; P < .001). The percentage of responder patients was higher in the low-dose morphine group, as early as at 1 week. Clinically meaningful (≥ 30%) and highly meaningful (≥ 50%) pain reduction from baseline was significantly higher in the low-dose morphine group (P < .001). A change in the assigned treatment occurred more frequently in the weak-opioid group, because of inadequate analgesia. The general condition of patients, which was based on the Edmonton Symptom Assessment System overall symptom score, was better in the morphine group. Adverse effects were similar in both groups. CONCLUSION In patients with cancer and moderate pain, low-dose morphine reduced pain intensity significantly compared with weak opioids, with a similarly good tolerability and an earlier effect.

Abstract
Context: Pain is a distressing symptom common to all stages and ubiquitous at all levels of care in cancer patients. However, there is a lack of scientific literature on prevalence, severity, predictors, and the quality of pain in cancer patients admitted to an Intensive Care Unit (ICU). Objectives: To elucidate the prevalence of pain, moderate to severe pain, neuropathic pain, chronic pain, and pain as the most distressing symptom in critically ill-cancer patients at the time of ICU admission. Methods: We prospectively interviewed 126 patients within first 24 h of admission to a medical ICU. The patients were assessed for the presence of pain, its severity, sites, duration, nature, and its impact as a distressing symptom. Numerical Rating Scale and self-report version of Leeds Assessment of Neuropathic Signs and Symptoms were used to elucidate intensity of pain and neuropathic pain, respectively. Demographic characteristics such as age and sex, primary site, and stage of cancer were considered for a possible correlation with the prevalence of pain. Results: Of 126 patients included in the study 95 (75.40%), 79 (62.70%), 34 (26.98%), and 17 (13.49%) patients had pain, moderate-severe, chronic, and neuropathic pain, respectively. The average duration of pain was 171.16 ± 716.50 days. Totally, 58 (46.03%) and 42 (42.01%) patients had at least one and more than equal to 2 neuropathic pain symptoms, respectively. The primary malignancies associated with the highest prevalence of pain were genitourinary, hematological, and head and neck whereas breast and lung cancers were associated with the highest prevalence of neuropathic and chronic pain, respectively. Conclusion: The prevalence of pain among critically ill-cancer patients is high. Assessment for pain at the time of ICU admission would ensure appropriate assessment for the presence, type, severity, and the significance imparted to it.

Use of the lung cancer-specific Quality of Life Questionnaire EORTC QLQ-LC13 in clinical trials: A systematic review of the literature 20 years after its development. Cancer 2015; 121:4300-23. [PMID: 26451520 DOI: 10.1002/cncr.29682] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2015] [Revised: 06/24/2015] [Accepted: 07/02/2015] [Indexed: 12/19/2022]
Abstract
The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality-of-life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty-six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ-LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials.

Abstract
Background Previous studies have reported CD44 expression influenced the development and progression of tumors. The aim of this study was to investigate whether single-nucleotide polymorphisms (SNPs) of the CD44 gene are associated with survival of non-small cell lung cancer (NSCLC) and occurrence rate of bone metastasis. Material/Methods A total of 234 patients with NSCLC between 2003 and 2010 were enrolled in this study and 468 healthy persons were used as controls. Two polymorphisms, rs13347 and rs187115, in the CD44 gene were genotyped using DNA from blood lymphocytes. For statistical analysis we used the chi-square test, Fisher’s exact test, Kaplan-Meier method, and log-rank test. Results CD44 gene rs13347 polymorphism was not associated with NSCLC risk. For rs187115, the association with NSCLC risk was observed (P<0.001). Allele G carriers had significantly higher occurrence rates of bone metastasis (OR=0.4, 95%CI: 0.20–0.64, P<0.001) and more advanced tumor stage (OR=2.6, 95%CI: 1.50–4.45, P=0.001) compared to carriers of allele A. The survival rates for patients with AA genotype were significantly higher than for patients with the AG+GG genotypes (P<0.001). In multivariate analysis of survival in NSCLC patients, significant predictors were CD44 gene (AG+GG) (RR=0.48, 95%CI: 0.34–0.68, P<0.001), tumor stage (RR=0.45, 95%CI: 0. 0.31–0.65, P<0.001), and bone metastasis (RR=1.52, 95%CI: 1.05–2.21, P=0.027). Conclusions CD44 gene rs187115 polymorphism is a potential predictive marker of survival in NSCLC patients, and is significantly correlated with bone metastasis and tumor stage.

Therapeutic Potential of Denosumab in Patients With Lung Cancer: Beyond Prevention of Skeletal Complications. Clin Lung Cancer 2015; 16:431-46. [PMID: 26264596 DOI: 10.1016/j.cllc.2015.06.004] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2015] [Revised: 06/09/2015] [Accepted: 06/16/2015] [Indexed: 12/29/2022]
Abstract
Approximately up to 40% of patients with lung cancer develop bone metastasis, with 22% to 59% of them experiencing skeletal-related events (SREs), which result in an important quality of life deterioration and economic burden. Denosumab, a fully human antibody that targets the receptor activator of nuclear factor-κB (RANK) ligand (RANKL), is indicated for prevention of SREs in patients with solid tumors and has demonstrated superiority in breast and prostate cancer, and in other solid tumors, in reducing the risk of first SRE by 17% versus zoledronic acid. In the subset of patients with non-small-cell lung carcinoma (NSCLC), denosumab has also shown a positive trend to SRE risk reduction. Denosumab might have direct or indirect antitumor effects. Cancer cells produce factors that stimulate increased bone resorption by osteoclasts, which in turn release tumor growth factors into the bone microenvironment, initiating a tumor/bone vicious cycle. An increasing body of evidence suggests RANK/RANKL signaling plays a role in this tumorigenesis. Both proteins are overexpressed in different tumor types including lung cancer cells. RANK/RANKL signaling activates nuclear factor-κB pathways related to lung carcinogenesis and increases intercellular adhesion molecule 1 expression and MEK/extracellular signal-regulated kinase phosphorylation, which in turn enhances tumor cell migration. In animal NSCLC models, denosumab delayed bone metastases and reduced skeletal tumor growth. In patients with lung cancer (post hoc analysis), denosumab prolonged overall survival by 1.2 months versus zoledronic acid (P = .01). This hypothesis-generating outcome warrants further investigation and 2 studies in lung cancer are ongoing to elucidate the therapeutic potential of denosumab beyond SRE prevention.

Impact of epidural analgesia on quality of life and pain in advanced cancer patients. Pain Manag Nurs 2014; 16:307-13. [PMID: 25439118 DOI: 10.1016/j.pmn.2014.08.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2014] [Revised: 08/07/2014] [Accepted: 08/07/2014] [Indexed: 11/20/2022]
Abstract
Patients with advanced cancer often experience chronic postoperative pain and poor quality of life. The objective of this study was to determine if epidural self-controlled analgesia reduced the incidence of chronic pain and improved the quality of life when compared with intravenous self-controlled analgesia. A total of 50 patients diagnosed with advanced cancer who received analgesia treatment were randomly divided into two groups, epidural self-controlled analgesia group (EA group, n = 26) and intravenous self-controlled analgesia group (IA group, n = 24). Visual analog scale (VAS) and Karnofsky score were used to assess the pain and the quality of life, respectively. A multifunction monitor was used to continuously record the physical signs of patients after treatment. The physical signs, such as heart failure, respiration, pulse, blood pressure, and oxygen saturation, in the two groups were better after analgesia treatment. Meanwhile, the respiration and oxygen saturation in the EA group were significantly improved compared with that of the IA group (p < .05). The VAS in the EA group was significantly lower than that in the IA group (p < .05), and the Karnofsky score in the EA group was significantly higher than that in the IA group (p < .05). Moreover, patients treated with EA felt more satisfied and experienced fewer complications than those with IA (p < .05). The epidural self-controlled analgesia may greatly improve the quality of life and relieve the pain in patients with advanced cancer.

Bone metastasis, skeletal-related events, and mortality in lung cancer patients: a Danish population-based cohort study. Lung Cancer 2014; 86:247-54. [PMID: 25240518 DOI: 10.1016/j.lungcan.2014.08.022] [Citation(s) in RCA: 92] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2014] [Accepted: 08/31/2014] [Indexed: 10/24/2022]
Abstract
OBJECTIVES To estimate the incidence rate of bone metastasis and subsequent skeletal-related events (SREs) (radiation to bone, spinal cord compression, fracture, and surgery to bone) in lung cancer patients and to quantify their impact on mortality. MATERIALS AND METHODS We conducted a nationwide cohort study of patients diagnosed with lung cancer between 1999 and 2010 in Denmark. We computed the cumulative incidence (%) of bone metastasis and subsequent SREs (treating death as a competing risk) and corresponding incidence rates (per 1000 person-years). Survival was evaluated using the Kaplan-Meier method for three dynamic lung cancer patient cohorts-no bone metastasis; bone metastasis without SREs; and bone metastasis with SREs. Based on a Cox proportional hazards model, we computed mortality rate ratios (MRRs) comparing mortality rates between these patient cohorts, adjusting for age, comorbidity, stage, and histology. Analyses were conducted for the lung cancer patient cohort overall and by histologic subtype. RESULTS We identified 29,720 patients with incident lung cancer (median follow-up: 7.3 months). The 1-year cumulative incidence of bone metastasis was 5.9%, and the 1-year cumulative incidence of subsequent SREs was 55.0%. The incidence of bone metastasis and SREs was higher in patients with non-small cell lung cancer (NSCLC) versus SCLC. One-year survival was 37.4% in patients with no bone metastasis; 12.1% in patients with bone metastasis without SREs; and 5.1% in patients with both bone metastasis and SREs. When mortality rates between patients with bone metastasis with and without an SRE were compared, 2-month mortality rates were similar, but the >2-month adjusted MRR was 2.0 (95% confidence interval: 1.7-2.2). CONCLUSION Bone metastases predict a poor prognosis in lung cancer patients. The majority of lung cancer patients with bone metastasis will also experience an SRE, which may further increase the rate of mortality.

Abstract
BACKGROUND Smoking and pain are prevalent and comorbid among patients with cancer. Limited work has compared pain experiences among current, former, and never (regular) smokers with lung and colorectal cancer. METHODS We studied pain experiences of patients with lung (n = 2390) and colorectal (n = 2993) cancer participating in the multi-regional Cancer Care Outcomes Research and Surveillance study. We examined reports of pain, pain treatment, pain severity, and pain-related interference within each cancer group by smoking status, adjusting for demographic, psychosocial, and cancer characteristics. RESULTS Among lung cancer patients, current smokers reported pain and receiving pain treatment more often than former smokers. Never smokers did not differ from current and former smokers on endorsement of pain; however, they reported pain treatment less often than their counterparts. Current smokers reported greater pain severity than former smokers after adjusting for other contributing factors; however, no differences were detected between current and never smokers. There were no differences in pain-related interference. Among colorectal cancer patients, current smokers reported pain and pain treatment more often than former and never smokers; however, the latter 2 groups did not differ. Current smokers also reported greater pain severity than never smokers after adjustments; however, no differences were detected between current and former smokers. An identical pattern of findings was observed for pain-related interference. CONCLUSIONS Many smokers with lung and colorectal cancer experience pain following a cancer diagnosis. Future work should assess if comprehensive smoking cessation treatments that address pain can reduce pain and facilitate smoking cessation among patients with cancer.

Abstract
PURPOSE In this study, we evaluated the analgesic potential of demethylating drugs on oral cancer pain. Although demethylating drugs could affect expression of many genes, we focused on the mu-opioid receptor (OPRM1) gene pathway, because of its role in pain processing. We determined the antinociceptive effect of OPRM1 re-expression in a mouse oral cancer model. EXPERIMENTAL DESIGN Using a mouse oral cancer model, we determined whether demethylating drugs produced antinociception through re-expression of OPRM1. We then re-expressed OPRM1 with adenoviral transduction and determined if, and by what mechanism, OPRM1 re-expression produced antinociception. To determine the clinical significance of OPRM1 on cancer pain, we quantified OPRM1 methylation in painful cancer tissues and nonpainful contralateral normal tissues of patients with oral cancer, and nonpainful dysplastic tissues of patients with oral dysplasia. RESULTS We demonstrated that OPRM1 was methylated in cancer tissue, but not normal tissue, of patients with oral cancer, and not in dysplastic tissues from patients with oral dysplasia. Treatment with demethylating drugs resulted in mechanical and thermal antinociception in the mouse cancer model. This behavioral change correlated with OPRM1 re-expression in the cancer and associated neurons. Similarly, adenoviral-mediated OPRM1 re-expression on cancer cells resulted in naloxone-reversible antinociception. OPRM1 re-expression on oral cancer cells in vitro increased β-endorphin secretion from the cancer, and decreased activation of neurons that were treated with cancer supernatant. CONCLUSION Our study establishes the regulatory role of methylation in cancer pain. OPRM1 re-expression in cancer cells produces antinociception through cancer-mediated endogenous opioid secretion. Demethylating drugs have an analgesic effect that involves OPRM1.

Abstract
Achieving balance in the appropriate use of opioids for the treatment of cancer pain is complex. The definition of “balance” is continually being modified. Palliative care professionals, pain specialists, and oncologists have long been advocating for the aggressive management of pain for patients with advanced cancer. Some progress has been made in this arena but barriers persist. Fear of addiction by patients, family members, and oncology professionals presents a serious obstacle to the provision of adequate pain control. This is further complicated by societal factors that receive extensive media coverage, such as diversion of prescribed opioids for recreational use and increasing deaths as a result of this inappropriate use of prescription opioids. This growing concern has led to more opioid regulation, which increases obstacles to pain management in this population. Another evolving concern is whether the long-term use of opioids is safe and effective. Data from the chronic nonmalignant pain literature suggest that toxicities may result and misuse has been underestimated, yet little information is available in the cancer population. These issues lead to serious questions regarding how balance might be successfully achieved for patients in an oncology setting. Can pain relief be provided while reducing negative consequences of treatment? Which patient should be prescribed what medications, in what situations, for what kind of pain, and who should be managing the pain?

Abstract
PURPOSE We investigated implanting computed tomography (CT)-guided (125)I seed to treat locally advanced non-small-cell lung cancer (NSCLC) after chemotherapy failure. METHODS From January 2005 to July 2010, we recruited 69 patients with locally advanced NSCLC who had each had first-line chemotherapy four to six times but had progressive disease; 34 received (125)I seed implantation with second-line chemotherapy (Group A) and 35 received second-line chemotherapy only (Group B). RESULTS Mean follow-up was 32 months (range 5-56 months). Overall 2-year local control rate for existing lung lesions was Group A: 39.9 %; Group B: 12.5 % (P < 0.05). The 1-, 3-year, and median overall survival was 68.7 and 20.8 % at 17.4 months in Group A; and 45.1 and 18.7 % at 11.3 months in Group B, respectively (P > 0.05). Local 3-, 24-month, and median progression-free survival was Group A: 100 and 79.1 % at 11 months; Group B: 76.5 and 18.7 % at 7.3 months, respectively. The groups did not significantly differ in treatment toxicity. Chest pain remission was Group A: 82.1 % (23/28); Group B: 30.8 % (8/26) (P < 0.05). Group A showed no radiation-related pneumonia, esophagitis, bronchial fistulae, or life-threatening morbidity. CONCLUSION CT-guided radioactive seed (125)I implantation procedure is safe and well tolerated in treating locally advanced NSCLC, with few complications. It has good local control rate and can relieve symptoms without increasing side effects.

Abstract
Pain treatment in Italy is far from being optimal. In order to improve this situation, the reporting of a complete assessment of pain in the clinical record became compulsory by law. Pain-related cancer protocols (143) were selected from the National Monitoring Centre of Clinical Trials Database and reviewed. Our data indicate that pain management is not being reported as it should be: treatment has been taken into account in only 36.4% of the protocols, and assessment in 37.1%. Furthermore, breakthrough cancer pain has never been reported. The main aim of cancer therapy is obviously control the disease, however Ethics Committees should pay close attention to pain therapy when evaluating clinical protocols.

Abstract
CONTEXT Pain is a major health care problem for the patients with cancer and one of the most frequent and disturbing cancer related symptoms. AIM To study the characteristics of pain in cancer patients and its pharmacological management by using a subjective self-assessment questionnaire and the World Health Organization (WHO)analgesic ladder for pain management. SETTINGS AND DESIGNS This study was conducted in the Oncology Wards of Penang Hospital, Penang, Malaysia. A questionnaire was developed to assess the pain characteristics and their effect on the patients' daily life activities and the information on the pharmacological management of the cancer pain. The cancer pain intensity was noted from the patients' medical database. METHOD AND MATERIAL By using the validated questionnaire, an observational, cross sectional study was conducted on the cancer patientswho were admitted in the oncology wards of Penang Hospital, Malaysia, for a period of 1 month. STATISTICAL ANALYSIS Descriptive statistics like mean, frequency and percentages were used for this study. RESULTS AND CONCLUSION A total of 42 patients out of 143, who fulfilled the criteria, were interviewed. The results showed mild pain in 66.7% (28) of the patients, moderate pain in 7.1% (3) and severe painin 26.2% (11). The normal daily life activities were affected by the pain in almost all the patients. Among the interviewed patients, sleep was affected in 88% (37) of the patients and the normal physical activity was affected in 92.9% (39) of the patients. Similarly, the pain decreased the appetite in 78.6% (33) of the patients, it affected the personal relationship in 35.7% (15), it affected the emotion in 71.5% (30) and it affected the visual activity in 33.6% (13) of the patients. Mild pain with distressing symptoms was not treated with any analgesic or adjuvant medications in 40.5% (17) of the patients. In contrast, all the patients with moderate and severe pain were treated with medications. Among them, 66.7% (2) of the patients with moderate pain and 90.9% (10) of the patients with severe pain were treated with analgesics as per the WHO analgesic ladder. The WHO analgesic ladder guide for pain management was followed in a majority of the cases, when analgesics were prescribed. However, there was inadequate treatment of the cancer pain in many patients with mild pain and, consequently, their quality of life was largely affected.
