  1. Pain and nociception: mechanisms of cancer-induced bone pain.

    2014-06-01

    Cancer pain, especially pain caused by metastasis to bone, is a severe type of pain, and unless the cause and consequences can be resolved, the pain will become chronic. As detection and survival among patients with cancer have improved, pain has become an increasing challenge, because traditional therapies are often only partially effective. Until recently, knowledge of cancer pain mechanisms was poor compared with understanding of neuropathic and inflammatory pain states. We now view cancer-induced bone pain as a complex pain state involving components of both inflammatory and neuropathic pain but also exhibiting elements that seem unique to cancer pain. In addition, the pain state is often unpredictable, and the intensity of the pain is highly variable, making it difficult to manage. The establishment of translational animal models has started to reveal some of the molecular components involved in cancer pain. We present the essential pharmacologic and neurobiologic mechanisms involved in the generation and continuance of cancer-induced bone pain and discuss these in the context of understanding and treating patients. We discuss changes in peripheral signaling in the area of tumor growth, examine spinal cord mechanisms of sensitization, and finally address central processing. Our aim is to provide a mechanistic background for the sensory characteristics of cancer-induced bone pain as a basis for better understanding and treating this condition.

    Full Text Available Bone pain is the most common type of pain in cancer. Bony metastases are common in advanced cancers, particularly in multiple myeloma, breast, prostate or lung cancer. Current pain-relieving strategies include the use of opioid-based analgesia, bisphosphonates and radiotherapy. Although patients experience some pain relief, these interventions may produce unacceptable side-effects which inevitably affect the quality of life. Acupuncture may represent a potentially valuable adjunct to existing strategies for pain relief and it is known to be relatively free of harmful side-effects. Although acupuncture is used in palliative care settings for all types of cancer pain the evidence-base is sparse and inconclusive and there is very little evidence to show its effectiveness in relieving cancer-induced bone pain (CIBP. The aim of this critical review is to consider the known physiological effects of acupuncture and discuss these in the context of the pathophysiology of malignant bone pain. The aim of future research should be to produce an effective protocol for treating CIBP with acupuncture based on a sound, evidence-based rationale. The physiological mechanisms presented in this review suggest that this is a realistic objective.

    Full Text Available The majority of patients with terminal breast cancer show signs of bone metastasis, the most common cause of pain in cancer. Clinically available drug treatment options for the relief of cancer-associated bone pain are limited due to either inadequate pain relief and/or dose-limiting side-effects. One of the major hurdles in understanding the mechanism by which breast cancer causes pain after metastasis to the bones is the lack of suitable preclinical models. Until the late twentieth century, all animal models of cancer induced bone pain involved systemic injection of cancer cells into animals, which caused severe deterioration of animal health due to widespread metastasis. In this mini-review we have discussed details of a recently developed and highly efficient preclinical model of breast cancer induced bone pain: Walker 256 cancer cell- induced bone pain in rats. The model involves direct localized injection of cancer cells into a single tibia in rats, which avoids widespread metastasis of cancer cells and hence animals maintain good health throughout the experimental period. This model closely mimics the human pathophysiology of breast cancer induced bone pain and has great potential to aid in the process of drug discovery for treating this intractable pain condition.

    Full Text Available Abstract Background Mechanisms driving cancer-induced bone pain are poorly understood. A central factor implicated to be a key player in the process of tumorigenesis, osteoclastogenesis and nociception is p38 MAPK. We determined the role of p38 MAPK in a mouse model of breast cancer induced bone pain in which mixed osteolytic and osteoblastic remodeling occurs. Results In cancer-treated mice, acute as well as chronic inhibition of p38 MAPK with SB203580 blocked flinching and guarding behaviors in a dose-dependent manner whereas no effect on thresholds to tactile stimuli was observed. Radiographic analyses of bones demonstrated that chronic inhibition of p38 MAPK reduced bone loss and incidence of spontaneous fracture in cancer-treated mice. Histological analysis of bones collected from mice treated with the p38 MAPK inhibitor showed complete absence of osteoblastic growth in the intramedullary space as well as significantly reduced tumor burden. Conclusions Blockade of non-evoked pain behaviors but not hypersensitivity suggests differences in the underlying mechanisms of specific components of the pain syndrome and a possibility to individualize aspects of pain management. While it is not known whether the role of p38 MAPK signaling can be expanded to other cancers, the data suggest a need for understanding molecular mechanisms and cellular events that initiate and maintain cancer-induced bone pain for effective management for both ongoing pain as well as breakthrough pain.

    Patients with tumors that metastasize to bone frequently suffer from debilitating pain, and effective therapies for treating bone cancer are lacking. This study employed a novel strategy in which herpes simplex virus (HSV) carrying a small interfering RNA (siRNA) targeting platelet-derived growth factor (PDGF) was used to alleviate bone cancer pain. HSV carrying PDGF siRNA was established and intrathecally injected into the cavum subarachnoidale of animals suffering from bone cancer pain and animals in the negative group. Sensory function was assessed by measuring thermal and mechanical hyperalgesia. The mechanism by which PDGF regulates pain was also investigated by comparing the differential expression of pPDGFRα/β and phosphorylated ERK and AKT. Thermal and mechanical hyperalgesia developed in the rats with bone cancer pain, and these effects were accompanied by bone destruction in the tibia. Intrathecal injection of PDGF siRNA and morphine reversed thermal and mechanical hyperalgesia in rats with bone cancer pain. In addition, we observed attenuated astrocyte hypertrophy, down-regulated pPDGFRα/β levels, reduced levels of the neurochemical SP, a reduction in CGRP fibers and changes in pERK/ERK and pAKT/AKT ratios. These results demonstrate that PDGF siRNA can effectively treat pain induced by bone cancer by blocking the AKT-ERK signaling pathway. PMID:27282805

    The purinergic P2X7 receptor is implicated in both neuropathic and inflammatory pain, and has been suggested as a possible target in pain treatment. However, the specific role of the P2X7 receptor in bone cancer pain is unknown. We demonstrated that BALB/cJ P2X7 receptor knockout (P2X7R KO) mice...... were susceptible to bone cancer pain and moreover had an earlier onset of pain-related behaviours compared with cancer-bearing, wild-type mice.

    Full Text Available Pre-clinical bone cancer pain models mimicking the human condition are required to respond to clinical realities. Breast or prostate cancer patients coping with bone metastases experience intractable pain, which affects their quality of life. Advanced monitoring is thus required to clarify bone cancer pain mechanisms and refine treatments. In our model of rat femoral mammary carcinoma MRMT-1 cell implantation, pain onset and tumor growth were monitored for 21 days. The surgical procedure performed without arthrotomy allowed recording of incidental pain in free-moving rats. Along with the gradual development of mechanical allodynia and hyperalgesia, behavioral signs of ambulatory pain were detected at day 14 by using a dynamic weight-bearing apparatus. Osteopenia was revealed from day 14 concomitantly with disorganization of the trabecular architecture (µCT. Bone metastases were visualized as early as day 8 by MRI (T(1-Gd-DTPA before pain detection. PET (Na(18F co-registration revealed intra-osseous activity, as determined by anatomical superimposition over MRI in accordance with osteoclastic hyperactivity (TRAP staining. Pain and bone destruction were aggravated with time. Bone remodeling was accompanied by c-Fos (spinal and ATF3 (DRG neuronal activation, sustained by astrocyte (GFAP and microglia (Iba1 reactivity in lumbar spinal cord. Our animal model demonstrates the importance of simultaneously recording pain and tumor progression and will allow us to better characterize therapeutic strategies in the future.

    Full Text Available Abstract Background Skeletal metastases are often accompanied by bone pain. To investigate the clinical meaning of bone pain associated with skeletal metastasis in breast cancer patients after surgery, we explored whether the presence of bone pain was due to skeletal-related events (SREs or survival (cause specific death, CSD, retrospectively. Methods Consecutive breast cancer patients undergoing surgery between 1988 and 1998 were examined for signs of skeletal metastasis until December 2006. Patients who were diagnosed as having skeletal metastasis were the subjects of this study. Bone scans were performed annually for 5, 7 or 10 years; they were also conducted if skeletal metastasis was suspected. Data concerning bone pain and tumor markers at the time of skeletal metastasis diagnosis, and data relating to various factors including tumors, lymph nodes and hormone receptors at the time of surgery, were investigated. The relationships between factors such as bone pain, SRE and CSD were analyzed using the Kaplan-Meier method and Cox's analysis. Results Skeletal metastasis occurred in 668 patients but the pain status of two patients was unknown, therefore 666 patients were included in the study. At the time of skeletal metastasis diagnosis 270 patients complained of pain; however, 396 patients did not. Analysis of data using Cox's and Kaplan-Meier methods demonstrated that patients without pain had fewer SREs and better survival rates than those with pain. Hazard ratios regarding SRE (base = patients without pain were 2.331 in univariate analysis and 2.243 in multivariate analysis. Hazard ratios regarding CSD (base = patients without pain were 1.441 in univariate analysis and 1.535 in multivariate analysis. Similar results were obtained when analyses were carried out using the date of surgery as the starting point. Conclusion Bone pain at diagnosis of skeletal metastasis was an indicator of increased SRE and CSD. However, these data did not

    2011-10-01

    Full Text Available Abstract Background Bone metastases are a common painful and debilitating consequence of castration-resistant prostate cancer (CPRC. Bone pain may predict patients' prognosis and there is a need to further explore CRPC patients' experiences of bone pain in the overall context of disease pathology. Due to the subjective nature of pain, assessments of pain severity, onset and progression are reliant on patient assessment. Patient reported outcome (PRO measures, therefore, are commonly used as key endpoints for evaluating the efficacy of CRPC treatments. Evidence of the content validity of leading PRO measures of pain severity used in CRPC clinical trials is, however, limited. Methods To document patients' experience of CRPC symptoms including pain, and their impact on health-related quality of life (HRQL, semi-structured in-depth qualitative interviews were conducted with 17 patients with CRPC and bone metastases. The content validity of the Present Pain Intensity (PPI scale from the McGill Pain Questionnaire (MPQ, and the 'Average Pain' and 'Worst Pain' items of the Brief Pain Inventory Short-Form (BPI-SF was also assessed. Results Patients with CRPC and bone metastases present with a constellation of symptoms that can have a profound effect on HRQL. For patients in this study, bone pain was the most prominent and debilitating symptom associated with their condition. Bone pain was chronic and, despite being generally well-managed by analgesic medication, instances of breakthrough cancer pain (BTcP were common. Cognitive debriefing of the selected PRO measures of pain severity highlighted difficulties among patients in understanding the verbal response scale (VRS of the MPQ PPI scale. There were also some inconsistencies in the way in which the BPI-SF 'Average Pain' item was interpreted by patients. In contrast, the BPI-SF 'Worst Pain' item was well understood and interpreted consistently among patients. Conclusions Study findings support the

    Cancer-induced bone pain can severely compromise the life quality of patients, while tolerance limits the use of opioids in the treatment of cancer pain. Monocyte chemoattractant protein-1 (MCP-1) is known to contribute to neuropathic pain. However, the role of spinal MCP-1 in the development of morphine tolerance in patients with cancer-induced bone pain remains unclear. The aim of the present study was to investigate the role of spinal MCP-1 in morphine tolerance in bone cancer pain rats (MTBP rats). Bone cancer pain was induced by intramedullary injection of Walker 256 cells into the tibia of the rats, while morphine tolerance was induced by continuous intrathecal injection of morphine over a period of 9 days. In addition, anti-MCP-1 antibodies were intrathecally injected to rats in various groups in order to investigate the association of MCP-1 with mechanical and heat hyperalgesia using the paw withdrawal threshold (PWT) and thermal withdrawal latency (TWL) tests, respectively. Furthermore, MCP-1 and CCR2 expression levels were measured using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis, and CCR2 expression levels were measured using RT-qPCR. The results indicated that MCP-1 and CCR2 expression levels were significantly increased in the spinal cord of MTBP rats. Intrathecal administration of anti-MCP-1 neutralizing antibodies was observed to attenuate the mechanical and thermal allodynia in MTBP rats. Therefore, the upregulation of spinal MCP-1 and CCR2 expression levels may contribute to the development of mechanical allodynia in MTBP rats. In conclusion, MCP-1/CCR2 signaling may serve a crucial role in morphine tolerance development in rats suffering from cancer-induced bone pain.

    Full Text Available To explore the effects and mechanisms of Xiaozheng Zhitong Paste (XZP on bone cancer pain, Wistar rats were inoculated with vehicle or prostate cancer PC-3 into the tibia bone and treated topically with inert paste, XZP at 15.75, 31.5, or 63 g/kg twice per day for 21 days. Their bone structural damage, nociceptive behaviors, bone osteoclast and osteoblast activity, and the levels of OPG, RANL, RNAK, PTHrP, IGF-1, M-CSF, IL-8, and TNF-α were examined. In comparison with that in the placebo group, significantly reduced numbers of invaded cancer cells, decreased levels of bone damage and mechanical threshold and paw withdrawal latency, lower levels of serum TRACP5b, ICTP, PINP, and BAP, and less levels of bone osteoblast and osteoclast activity were detected in the XZP-treated rats (P<0.05. Moreover, significantly increased levels of bone OPG but significantly decreased levels of RANL, RNAK, PTHrP, IGF-1, M-CSF, IL-8, and TNF-α were detected in the XZP-treated rats (P<0.05 for all. Together, XZP treatment significantly mitigated the cancer-induced bone damage and bone osteoclast and osteoblast activity and alleviated prostate cancer-induced bone pain by modulating the RANKL/RANK/OPG pathway and bone cancer-related inflammation in rats.

    Cancer-induced bone pain is described as dull, aching ongoing pain. Ongoing bone cancer pain was characterized after intratibial injection of breast cancer cells in rats. Cancer produced time-dependent bone remodeling and tactile hypersensitivity but no spontaneous flinching. Conditioned place preference (CPP) and enhanced dopamine (DA) release in the nucleus accumbens (NAc) shell was observed after peripheral nerve block (PNB) selectively in tumor-bearing rats revealing nociceptive-driven ongoing pain. Oral diclofenac reversed tumor-induced tactile hypersensitivity but did not block PNB-induced CPP or NAc DA release. Tumor-induced tactile hypersensitivity, and PNB-induced CPP and NAc DA release, was blocked by prior subcutaneous implantation of a morphine pellet. In sham rats, morphine produced a modest but sustained increase in NAc DA release. In contrast, morphine produced a transient 5-fold higher NAc DA release in tumor bearing rats compared with sham morphine rats. The possibility that this increased NAc DA release reflected the reward of pain relief was tested by irreversible blockade of rostral anterior cingulate cortex (rACC) μ-opioid receptors (MORs). The rACC MOR blockade prevented the morphine-induced transient increased NAc DA release in tumor bearing rats but did not affect morphine-induced effects in sham-operated animals. Consistent with clinical experience, ongoing cancer pain was controlled by morphine but not by a dose of diclofenac that reversed evoked hypersensitivity. Additionally, the intrinsic reward of morphine can be dissociated from the reward of relief of cancer pain by blockade of rACC MOR. This approach allows mechanistic and therapeutic assessment of ongoing cancer pain with likely translation relevance.

    Full Text Available Abstract Pain often accompanies cancer and most current therapies for treating cancer pain have significant unwanted side effects. Targeting nerve growth factor (NGF or its cognate receptor tropomyosin receptor kinase A (TrkA has become an attractive target for attenuating chronic pain. In the present report, we use a mouse model of bone cancer pain and examine whether oral administration of a selective small molecule Trk inhibitor (ARRY-470, which blocks TrkA, TrkB and TrkC kinase activity at low nm concentrations has a significant effect on cancer-induced pain behaviors, tumor-induced remodeling of sensory nerve fibers, tumor growth and tumor-induced bone remodeling. Early/sustained (initiated day 6 post cancer cell injection, but not late/acute (initiated day 18 post cancer cell injection administration of ARRY-470 markedly attenuated bone cancer pain and significantly blocked the ectopic sprouting of sensory nerve fibers and the formation of neuroma-like structures in the tumor bearing bone, but did not have a significant effect on tumor growth or bone remodeling. These data suggest that, like therapies that target the cancer itself, the earlier that the blockade of TrkA occurs, the more effective the control of cancer pain and the tumor-induced remodeling of sensory nerve fibers. Developing targeted therapies that relieve cancer pain without the side effects of current analgesics has the potential to significantly improve the quality of life and functional status of cancer patients.

    Full Text Available Although bone cancer pain is still not fully understood by scientists and clinicians alike, studies suggest that toll like receptor 4 (TLR4 plays an important role in the initiation and/or maintenance of pathological pain state in bone cancer pain. A promising treatment for bone cancer pain is the downregulation of TLR4 by RNA interference; however, naked siRNA (small interference RNA is not effective in long-term treatments. In order to concoct a viable prolonged treatment for bone cancer pain, an inducible lentivirus LvOn-siTLR4 (tetracycline inducible lentivirus carrying siRNA targeting TLR4 was prepared and the antinociception effects were observed in bone cancer pain rats induced by Walker 256 cells injection in left leg. Results showed that LvOn-siTLR4 intrathecal injection with doxycycline (Dox oral administration effectively reduced the nociception induced by Walker 256 cells while inhibiting the mRNA and protein expression of TLR4. Proinflammatory cytokines as TNF-α and IL-1β in spinal cord were also decreased. These findings suggest that TLR4 could be a target for bone cancer pain treatment and tetracycline inducible lentivirus LvOn-siTLR4 represents a new potential option for long-term treatment of bone cancer pain.

    Ethnopharmacological relevance The herbal analgesic gel Tong-Luo-San-Jie (TLSJ) and its modifications are used in traditional Chinese medicine to manage cancer pain. However, its mechanisms are still unknown. Aim of the study To investigate the effects and mechanisms of TLSJ gel on bone cancer pain in a rat model. Materials and Methods A bone cancer pain rat model was established by inoculating Walker 256 rat carcinoma cells directly into the right tibial medullary cavity of Sprague-Dawley rats (150–170 g); Phosphate buffered saline (PBS) tibial inoculation was used as control. Cancer-bearing rats were treated twice a day with external TLSJ gel (0.5 g/cm2/day) or inert gel control for 21 days (n=10/group). Behavioral tests such as mechanical threshold and paw withdrawal latency (PWL) were carried out. Osteoclastic activities were determined and carboxyterminal pyridinoline cross-linked type I collagen telopeptides (ICTP) and bone-specific alkaline phosphatase (BAP) concentrations were detected with ELISA after treatment. Adverse effects were monitored, and biochemical and histological tests were performed in naïve rats treated with local TLSJ gel for six weeks. Results TLSJ treatment significantly restored bone cancer-induced decrease of PWL and mechanical threshold compared to inert gel. It also decreased the level of blood serum ICTP and BAP and inhibited osteoclast activities. No adverse effects or abnormal biochemical and histological changes were detected after TLSJ treatment. Conclusion The present study shows that TLSJ significantly inhibits bone cancer-induced thermal and mechanical sensitization. It suggests that the gel may be useful in managing cancer pain and that it may act by inhibiting osteoclastic activity. PMID:22960543

    Bone cancer pain is a major clinical problem and remains difficult to treat. ATP-sensitive potassium (KATP) channels may be involved in regulating nociceptive transmission at the spinal cord level. We determined the role of spinal KATP channels in the control of mechanical hypersensitivity in a rat model of bone cancer pain. The rat model of bone cancer pain was induced by implanting rat mammary gland carcinoma cells (Walker256) into the tibias. KATP modulators (pinacidil and glibenclamide) or the specific Kir6.2-siRNA were injected via an intrathecal catheter. The mechanical withdrawal threshold of rats was tested using von Frey filaments. The Kir6.2 mRNA and protein levels were measured by quantitative PCR and western blots, respectively. Intrathecal injection of pinacidil, a KATP channel opener, significantly increased the tactile withdrawal threshold of cancer cell-injected rats in a dose-dependent manner. In contrast, intrathecal delivery of glibenclamide, a KATP channel blocker, or the specific Kir6.2-siRNA significantly reduced the tactile withdrawal threshold of cancer cell-injected rats. The mRNA and protein levels of Kir6.2 in the spinal cord of cancer cell-injected rats were significantly lower than those in control rats. Our findings suggest that the KATP channel expression level in the spinal cord is reduced in bone cancer pain. Activation of KATP channels at the spinal level reduces pain hypersensitivity associated with bone cancer pain.

    Full Text Available Human pheochromocytoma cells, which are demonstrated to contain and release met-enkephalin and norepinephrine, may be a promising resource for cell therapy in cancer-induced intractable pain. Intrathecal injection of alginate-poly (l lysine-alginate (APA microencapsulated human pheochromocytoma cells leads to antinociceptive effect in a rat model of bone cancer pain, and this effect was blocked by opioid antagonist naloxone and alpha 2-adrenergic antagonist rauwolscine. Neurochemical changes of cerebrospinal fluid are in accordance with the analgesic responses. Taken together, these data support that human pheochromocytoma cell implant-induced antinociception was mediated by met-enkephalin and norepinephrine secreted from the cell implants and acting at spinal receptors. Spinal implantation of microencapsulated human pheochromocytoma cells may provide an alternative approach for the therapy of chronic intractable pain.

    Prostate cancer (PCa) has a high propensity for metastasis to bone. Despite the availability of multiple treatment options for relief of PCa-induced bone pain (PCIBP), satisfactory relief of intractable pain in patients with advanced bony metastases is challenging for the clinicians because currently available analgesic drugs are often limited by poor efficacy and/or dose-limiting side effects. Rodent models developed in the past decade show that the pathobiology of PCIBP comprises elements of inflammatory, neuropathic and ischemic pain arising from ectopic sprouting and sensitization of sensory nerve fibres within PCa-invaded bones. In addition, at the cellular level, PCIBP is underpinned by dynamic cross talk between metastatic PCa cells, cellular components of the bone matrix, factors associated with the bone microenvironment as well as peripheral components of the somatosensory system. These insights are aligned with the clinical management of PCIBP involving use of a multimodal treatment approach comprising analgesic agents (opioids, NSAIDs), radiotherapy, radioisotopes, cancer chemotherapy agents and bisphosphonates. However, a major drawback of most rodent models of PCIBP is their short-term applicability due to ethical concerns. Thus, it has been difficult to gain insight into the mal(adaptive) neuroplastic changes occurring at multiple levels of the somatosensory system that likely contribute to intractable pain at the advanced stages of metastatic disease. Specifically, the functional responsiveness of noxious circuitry as well as the neurochemical signature of a broad array of pro-hyperalgesic mediators in the dorsal root ganglia and spinal cord of rodent models of PCIBP is relatively poorly characterized. Hence, recent work from our laboratory to develop a protocol for an optimized rat model of PCIBP will enable these knowledge gaps to be addressed as well as identification of novel targets for drug discovery programs aimed at producing new analgesics

    Background:Calpain,a calcium-dependent cysteine protease,has been demonstrated to regulate osteoclastogenesis,which is considered one of the major reasons for cancer-induced bone pain (CIBP).In the present study,calpain inhibitor was applied in a rat CIBP model to determine whether it could reduce CIBP through regulation of osteoclastogenesis activity.Methods:A rat CIBP model was established with intratibial injection of Walker 256 cells.Then,the efficacy of intraperitoneal administered calpain inhibitor Ⅲ (MDL28170,1 mg/kg) on mechanical withdrawal threshold (MWT) of bilateral hind paws was examined on postoperative days (PODs) 2,5,8,11,and 14.On POD 14,the calpain inhibitor's effect on tumor bone tartrate-resistant acid phosphatase (TRAP) stain and radiology was also carefully investigated.Results:Pain behavioral tests in rats showed that the calpain inhibitor effectively attenuated MWTs of both the surgical side and contralateral side hind paws on POD 5,8,and 11 (P < 0.05).TRAP-positive cell count of the surgical side bone was significantly decreased in the calpain inhibitor group compared with the vehicle group (P < 0.05).However,bone resorption and destruction measured by radiographs showed no difference between the two groups.Conclusions:Calpain inhibitor can effectively reduce CIBP of both the surgical side and nonsurgical side after tumor injection in a rat CIBP model.It may be due to the inhibition of receptor activator of nuclear factor-kappa B ligand-induced osteoclastogenesis.Whether a calpain inhibitor could be a novel therapeutic target to treat CIBP needs further investigation.

    Full Text Available Background: The primary aim of this prospective non-randomized study was to evaluate the effect of hemi-body irradiation (HBI on pain and quality of life in cancer patients with extensive bone metastases. The secondary aim was to evaluate side-effects and cost-effectiveness of the treatment. Materials and Methods: Between March 2008 and December 2010, a total of 23 (male = 14, female = 9, median age = 60 years diagnosed cases of metastatic cancer patients (prostate = 11, breast = 6, and lung = 6 received HBI, which was delivered as lower (n = 7 (dose = 8 Gy, upper (n = 8 (dose = 6 Gy, or sequential HBI (n = 8 with a Telecobalt unit (Theratron 780C. Among them, one lung cancer patient died at 2 months and one prostate cancer patient defaulted after the second follow-up. Thus, 21 patients (male = 13, female = 8, median age = 65 years (prostatic cancer = 10, breast cancer = 6, and lung cancer = 5 were followed up for a minimum of 6 months. Evaluations were performed before and at 2, 4, 8, 16, and 24 weeks after treatment. Pain evaluation was done by Visual Analogue Scale (VAS, Verbal Rating Scale (VRS, Percentage of Pain Relief (PRR, and Global Pain Score (GPS. Toxicity was assessed by CTC v-3 toxicity scores in the medical record. Assessment of oral morphine consumption was done before and after radiation using paired t-test, and correlation analysis was also done with decrease of morphine consumption and reduction of pain score using statistical analysis. Results: Response (control of pain was partial (PR in 67% and complete (CR in 22% of patients. For most patients, the pain control lasted throughout the follow-up period (6 months. From 66.66% patients requiring 13 or more Morphine (10 mg tablets per day prior to HBI, none of the patients required to consume 13 or more Morphine (10 mg tablets per day following HBI, which was correlated with significant reduction in various pain scores (P < 0.05.

Over 13 days, rats progressively developed a tumor within the distal femoral epiphysis. On days 3, 7, 10, and 13 post injection, rats were subjected to the incapacitance and Randall–Selitto behavioral tests as they are believed to be indirect reflections of tumor induced pain. Ipsilateral hind limbs were subjected to X-ray and computed tomography (CT scans and histological sections were stained with hematoxylin and eosin (H&E.Results: Intra femoral injections of MLL cells resulted in the progressive development of a tumor leading to bone destruction and nociceptive behaviors. Tumor development resulted in the redistribution of weight to the contralateral hind leg and significantly reduced the paw withdrawal threshold of the ipsilateral hind paw as observed via the incapacitance and Randall–Selitto tests, respectively. X-ray and computed tomography scans along with H&E stains indicated tumor-associated structural damage to the distal femur. This model was challenged with administration of meloxicam. Compared with vehicle-injected controls, the meloxicam-treated rats displayed smaller nociceptive responses as observed with the incapacitance and Randall–Selitto tests, suggesting that meloxicam was effective in reducing the pain-related symptoms displayed by model animals and that the model behaved in a predictable way to cyclooxygenase-2 treatment.Conclusions: This

    Resiniferatoxin (RTX) is the most potent among all known endogenous and synthetic agonists for the transient receptor potential vanilloid 1 (TRPV1) receptor, which is a calcium-permeable nonselective cation channel, expressed on the peripheral and central terminals of small-diameter sensory neurons. Prolonged calcium influx induced by RTX causes cytotoxicity and death of only those sensory neurons that express the TRPV1 ion channel leading to selective targeting and permanent deletion of the TRPV1-expressing C-fiber neuronal cell bodies in the dorsal root ganglia. The goal of this project was to provide preclinical efficacy data, that intrathecal RTX could provide effective pain relief and improve function in dogs with bone cancer without significant long-term side effects. In a single-blind, controlled study, 72 companion dogs with bone cancer pain were randomized to standard of care analgesic therapy alone (control, n = 36) or 1.2 μg/kg intrathecal RTX in addition to standard of care analgesic therapy (treated, n = 36). Significantly more dogs in the control group (78%) required unblinding and adjustment in analgesic protocol or euthanasia within 6 weeks of randomization, than dogs that were treated with RTX (50%; P dogs in the control group required unblinding significantly sooner than dogs that had been treated with RTX (P dogs without any evidence of development of deafferentation pain syndrome that can be seen with neurolytic therapies.

    Full Text Available Treating cancer pain continues to possess a major challenge. Here, we report that a traditional Chinese medicine Xiao-Ai-Tong (XAT can effectively suppress pain and adverse reactions following morphine treatment in patients with bone cancer pain. Visual Analogue Scale (VAS and Quality of Life Questionnaire (EORTC QLQ-C30 were used for patient’s self-evaluation of pain intensity and evaluating changes of adverse reactions including constipation, nausea, fatigue, and anorexia, respectively, before and after treatment prescriptions. The clinical trials showed that repetitive oral administration of XAT (200 mL, bid, for 7 consecutive days alone greatly reduced cancer pain. Repetitive treatment with a combination of XAT and morphine (20 mg and 30 mg, resp. produced significant synergistic analgesic effects. Meanwhile, XAT greatly reduced the adverse reactions associated with cancer and/or morphine treatment. In addition, XAT treatment significantly reduced the proinflammatory cytokines interleukin-1β and tumor necrosis factor-α and increased the endogenous anti-inflammatory cytokine interleukin-10 in blood. These findings demonstrate that XAT can effectively reduce bone cancer pain probably mediated by the cytokine mechanisms, facilitate analgesic effect of morphine, and prevent or reduce the associated adverse reactions, supporting a use of XAT, alone or with morphine, in treating bone cancer pain in clinic.

    Cancer pain, especially cancer-induced bone pain, affects the quality of life of cancer patients, and current treatments for this pain are limited. The present study demonstrates that spinal extracellular signal-regulated kinase (ERK) activation in glial cells plays a crucial role in cancer-induced bone pain. From day 4 to day 21 after the intra-tibia inoculation with Walker 256 mammary gland carcinoma cells, significant mechanical allodynia was observed as indicated by the decrease of mechanical withdrawal thresholds in the von Frey hair test. Intra-tibia inoculation with carcinoma cells induced a vast and persistent (>21 D) activation of ERK in the bilateral L2-L3 and L4-L5 spinal dorsal horn. The increased pERK1/2-immunoreactivity was observed in both Iba-1-expressing microglia and GFAP-expressing astrocytes but not in NeuN-expressing neurons. A single intrathecal injection of the selective MEK (ERK kinase) inhibitors PD98059 (10 μg) on day 12 and U0126 (1.25 and 3 μg) on day 14, attenuated the bilateral mechanical allodynia in the von Frey hair test. Altogether, our results suggest that ERK activation in spinal microglia and astrocytes is correlated with the onset of allodynia and is important for allodynia maintenance in the cancer pain model. This study indicated that inhibition of the ERK pathway may provide a new therapy for cancer-induced bone pain.

    Mechanisms underlying bone cancer-induced pain are largely unknown. Previous studies indicate that neuroinflammation in the spinal dorsal horn is especially involved. Being first reported as a nonhistone chromosomal protein, high-mobility group box 1 (HMGB1) is now implicated as a mediator of inflammation. We hypothesized that HMGB1 could trigger the release of cytokines in the spinal dorsal horn and contribute to bone cancer pain. To test this hypothesis, we first built a bone cancer pain model induced by intratibal injection of Walker 256 mammary gland carcinoma cells. The structural damage to the tibia was monitored by radiological analysis. The mechanical allodynia was measured and the expression of spinal HMGB1 and IL-1{beta} was evaluated. We observed that inoculation of cancer cells, but not heat-killed cells, induced progressive bone destruction from 9 d to 21 d post inoculation. Behavioral tests demonstrated that the significant nociceptive response in the cancer cells-injected rats emerged on day 9 and this kind of mechanical allodynia lasted at least 21 d following inoculation. Tumor cells inoculation significantly increased HMGB1 expression in the spinal dorsal horn, while intrathecal injecting a neutralizing antibody against HMGB1 showed an effective and reliable anti-allodynia effect with a dose-dependent manner. IL-1{beta} was significantly increased in caner pain rats while intrathecally administration of anti-HMGB1 could decrease IL-1{beta}. Together with previous reports, we predict that bone cancer induces HMGB1 production, enhancing spinal IL-1{beta} expression and thus modulating spinal excitatory synaptic transmission and pain response.

    Full Text Available An overwhelming amount of evidence demonstrates sex-induced variation in pain processing, and has thus increased the focus on sex as an essential parameter for optimization of in vivo models in pain research. Mammary cancer cells are often used to model metastatic bone pain in vivo, and are commonly used in both males and females. Here we demonstrate that compared to male rats, female rats have an increased capacity for recovery following inoculation of MRMT-1 mammary cells, thus potentially causing a sex-dependent bias in interpretation of the data.

One of the reasons is that mechanisms underlying bone cancer pain are not solved completely. Our previous studies have shown that brain-derived neurotrophic factor (BDNF, known as a member of the neurotrophic family, is an important molecule in the pathological pain state in some pain models. We hypothesized that expression changes of BDNF may be one of the factors related to bone cancer pain; in this study, we investigated changes of BDNF expression in dorsal root ganglia in a rat bone cancer pain model. As we expected, BDNF mRNA (messenger ribonucleic acid and protein were significantly increased in L3 dorsal root ganglia after intra-tibial inoculation of MRMT-1 rat breast cancer cells. Among the eleven splice-variants of BDNF mRNA, exon 1–9 variant increased predominantly. Interestingly, the up-regulation of BDNF is localized in small neurons (mostly nociceptive neurons but not in medium or large neurons (non-nociceptive neurons. Further, expression of nerve growth factor (NGF, which is known as a specific promoter of BDNF exon 1–9 variant, was significantly increased in tibial bone marrow. Our findings suggest that BDNF is a key molecule in bone cancer pain, and NGF-BDNF cascade possibly develops bone cancer pain. Keywords: BDNF, bone cancer pain, chronic pain, nerve growth

    Full Text Available Pain from bone metastases of breast cancer origin is treated with localized radiation. Modulating doses and schedules has shown little efficacy in improving results. Given the synergistic therapeutic effect reported for combined systemic chemotherapy with local radiation in anal, rectal, and head and neck malignancies, we sought to evaluate the tolerability and efficacy of combined capecitabine and radiation for palliation of pain due to bone metastases from breast cancer.Twenty-nine women with painful bone metastases from breast cancer were treated with external beam radiation in 10 fractions of 3 Gy, 5 fractions a week for 2 consecutive weeks. Oral capecitabine 700 mg/m(2 twice daily was administered throughout radiation therapy. Rates of complete response, defined as a score of 0 on a 10-point pain scale and no increase in analgesic consumption, were 14% at 1 week, 38% at 2 weeks, 52% at 4 weeks, 52% at 8 weeks, and 48% at 12 weeks. Corresponding rates of partial response, defined as a reduction of at least 2 points in pain score without an increase in analgesics consumption, were 31%, 38%, 28%, 34% and 38%. The overall response rate (complete and partial at 12 weeks was 86%. Side effects were of mild intensity (grade I or II and included nausea (38% of patients, weakness (24%, diarrhea (24%, mucositis (10%, and hand and foot syndrome (7%.External beam radiation with concurrent capecitabine is safe and tolerable for the treatment of pain from bone metastases of breast cancer origin. The overall and complete response rates in our study are unusually high compared to those reported for radiation alone. Further evaluation of this approach, in a randomized study, is warranted.ClinicalTrials.gov NCT01784393NCT01784393.

    Full Text Available Objective. To explore the efficacy of electroacupuncture treatment in cancer induced bone pain (CIBP rat model with morphine tolerance and explore changes of calcitonin-gene related peptide (CGRP expression in dorsal root ganglion (DRG. Methods. Forty SD rats were divided into five groups: sham, CIBP (B, CIBP + morphine (BM, CIBP + electroacupuncture (BE, and CIBP + morphine + electroacupuncture (BME. B, BM, BE, and BME groups were prepared CIBP model. The latter three groups then accepted morphine, electroacupuncture, and morphine combined electroacupuncture, separately, nine days consecutively (M1 to M9. Mechanical withdraw threshold (MWT was evaluated. Results. BE group only had differences in M1, M2, and M3 compared to B group (P<0.01. From M5, BM group showed significantly decreased MWT. Electroacupuncture could obtain analgesic effects only at early stage (M1 to M5. From M5 to M9, BME had the differences with BM group (P<0.01. IOD value of CGRP in BM and BME was substantially less than in B group. CGRP in BME was significantly lower than that in BM group (P<0.01. Conclusion. When used in combination with electroacupuncture, morphine could result in improving analgesic effects and reducing tolerance. CGRP may be associated with pain behaviors.

    Full Text Available Cancer-induced bone pain (CIBP is a severe type of chronic pain. It is imperative to explore safe and effective analgesic drugs for CIBP treatment. Baicalein (BE, isolated from the traditional Chinese herbal medicine Scutellaria baicalensis Georgi (or Huang Qin, has been demonstrated to have anti-inflammatory and neuroprotective effects. In this study, we examined the effect of BE on CIBP and the mechanism of this effect. Intrathecal and oral administration of BE at different doses could alleviate the mechanical allodynia in CIBP rats. Intrathecal 100 μg BE could inhibit the production of IL-6 and TNF-α in the spinal cord of CIBP rats. Moreover, intrathecal 100 μg BE could effectively inhibit the activation of p-p38 and p-JNK MAPK signals in CIBP rats. The analgesic effect of BE may be associated with the inhibition of the expression of the inflammatory cytokines IL-6 and TNF-α and through the activation of p-p38 and p-JNK MAPK signals in the spinal cord. These findings suggest that BE is a promising novel analgesic agent for CIBP.

    Abstract Bone-seeking radiopharmaceuticals and bisphosphonates may be indicated in patients with cancer with painful osseous metastases to palliate pain symptoms or to prevent skeletal-related events. Both pharmaceuticals may have an additive or even synergistic palliative effect. The combined use of bone-seeking radiopharmaceuticals and bisphosphonates is, however, controversial because of assumed competition between both phosphonate-compounds at the bone level. We report a case of hormone-refractory prostate cancer (HRPC) with multiple painful osseous metastases. The patient was treated with samarium-153-ethylenediaminetetramethylphosphonic acid ((153)Sm-EDTMP; Quadramet, CIS bio International, Saclay, France) in combination with zoledronic acid (Zometa, Novartis, Stein, Switzerland). He was treated for 6 months with 4 weekly intervals of zoledronic acid in combination with 3 monthly intervals of (153)Sm-EDTMP. No negative interaction was found, toxicity was low, and efficacy high. He experienced a total relief of pain, a significant decrease of prostate-specific antigen (PSA) and, surprisingly, a significant decrease of tumor burden.

    Herbal analgesic Xiaozheng Zhitong Paste (XZP) and related modifications are often used in traditional Chinese medicine to manage cancer pain. However, its underlying mechanism remains unknown. To investigate the effects and mechanism of XZP on bone cancer pain in a rat model of breast cancer-induced bone pain, a bone cancer pain model was established by inoculating Walker 256 cells into Wistar rats. Bone cancer-bearing rats were topically treated with different doses of XZP or injected with 5 mg/kg of osteoprotegerin (OPG) as positive control. Bone destruction, bone mineral content (BMC) and bone mineral density (BMD) were analyzed by radiology. Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were examined to determine pain levels. Trypsin, TNF-α and IL-1β serum levels were determined using enzyme-linked immunosorbent assay (ELISA). Central sensitization markers such as c-Fos, GFAP, IBA1 and CGRP, as well as proteinase-activated receptor 2 (PAR2) signaling pathway mediators such as PAR2, PKC-γ, PKA and TRPV1, were determined by quantitative RT-PCR and western blotting assay. XZP treatment significantly mitigated bone cancer-related nociceptive behavior, bone damage, BMC and BMD; and decreased radiological scores in rats. XZP treatment significantly inhibited IBA1, GFAP, c-Fos and CGRP expressions in the spinal cord; and significantly mitigated trypsin, TNF-α and IL-1β serum levels. Furthermore, PAR2, PKC-γ, PKA and TRPV1 relative mRNA levels and protein expression in bone lesions were significantly reduced in rats treated with XZP. XZP significantly alleviates breast cancer-induced bone pain by inhibiting the PAR2 signaling pathway.

    Background. This study aimed to investigate the use of human bone marrow mesenchymal stem cells (hBMSCs) genetically engineered with the human proenkephalin (hPPE) gene to treat bone cancer pain (BCP) in a rat model. Methods. Primary cultured hBMSCs were passaged and modified with hPPE, and the cell suspensions (6 × 106) were then intrathecally injected into a rat model of BCP. Paw mechanical withdrawal threshold (PMWT) was measured before and after BCP. The effects of hPPE gene transfer on hBMSC bioactivity were analyzed in vitro and in vivo. Results. No changes were observed in the surface phenotypes and differentiation of hBMSCs after gene transfer. The hPPE-hBMSC group showed improved PMWT values on the ipsilateral side of rats with BCP from day 12 postoperatively, and the analgesic effect was reversed by naloxone. The levels of proinflammatory cytokines such as IL-1β and IL-6 were ameliorated, and leucine-enkephalin (L-EK) secretion was augmented, in the hPPE-engineered hBMSC group. Conclusion. The intrathecal administration of BMSCs modified with the hPPE gene can effectively relieve pain caused by bone cancer in rats and might be a potentially therapeutic tool for cancer-related pain in humans.

    Bone cancer pain is a common symptom in cancer patients with bone metastases and the underlying mechanisms are largely unknown. The aim of this study is to explore the endogenous analgesic mechanisms to develop new therapeutic strategies for bone-cancer induced pain (BCIP) as a result of metastases. MRMT-1 tumor cells were injected into bilateral tibia of rats and X-rays showed that the area suffered from bone destruction, accompanied by an increase in osteoclast numbers. In addition, rats with bone cancer showed apparent mechanical and thermal hyperalgesia at day 28 after intratibial MRMT-1 inoculation. However, intrathecal injection of morphine or lentivirus-mediated glial cell line-derived neurotrophic factor RNAi (Lvs-siGDNF) significantly attenuated mechanical and thermal hyperalgesia, as shown by increases in paw withdrawal thresholds and tail-flick latencies, respectively. Furthermore, Lvs-siGDNF interference not only substantially downregulated GDNF protein levels, but also reduced substance P immunoreactivity and downregulated the ratio of pERK/ERK, where its activation is crucial for pain signaling, in the spinal dorsal horn of this model of bone-cancer induced pain. In this study, Lvs-siGDNF gene therapy appeared to be a beneficial method for the treatment of bone cancer pain. As the effect of Lvs-siGDNF to relieve pain was similar to morphine, but it is not a narcotic, the use of GDNF RNA interference may be considered as a new therapeutic strategy for the treatment of bone cancer pain in the future.

    Background cAMP response element binding protein (CREB)-dependent gene expression plays an important role in central sensitization. CREB-regulated transcription coactivator 1 (CRTC1) dramatically increases CREB-mediated transcriptional activity. Brain-derived neurotrophic factor, N-methyl-d-aspartate receptor subunit 2B, and miRNA-212/132, which are highly CREB responsive, function downstream from CREB/CRTC1 to mediate activity-dependent synaptic plasticity and in turn loops back to amplify CREB/CRTC1 signaling. This study aimed to investigate the role of spinal CRTC1 in the maintenance of bone cancer pain using an RNA interference method. Results Osteosarcoma cells were implanted into the intramedullary space of the right femurs of C3H/HeNCrlVr mice to induce bone cancer pain. Western blotting was applied to examine the expression of spinal phospho-Ser133 CREB and CRTC1. We further investigated effects of repeated intrathecal administration with Adenoviruses expressing CRTC1-small interfering RNA (siRNA) on nociceptive behaviors and on the upregulation of CREB/CRTC1-target genes associated with bone cancer pain. Inoculation of osteosarcoma cells induced progressive mechanical allodynia and spontaneous pain, and resulted in upregulation of spinal p-CREB and CRTC1. Repeated intrathecal administration with Adenoviruses expressing CRTC1-siRNA attenuated bone cancer–evoked pain behaviors, and reduced CREB/CRTC1-target genes expression in spinal cord, including BDNF, NR2B, and miR-212/132. Conclusions Upregulation of CRTC1 enhancing CREB-dependent gene transcription in spinal cord may play an important role in bone cancer pain. Inhibition of spinal CRTC1 expression reduced bone cancer pain. Interruption to the positive feedback circuit between CREB/CRTC1 and its targets may contribute to the analgesic effects. These findings may provide further insight into the mechanisms and treatment of bone cancer pain. PMID:27060162

    Previous studies have demonstrated that sigma-1 receptor plays important roles in the induction phase of rodent neuropathic pain; however, whether it is involved in bone cancer pain (BCP) and the underlying mechanisms remain elusive. The aim of this study was to examine the potential role of the spinal sigma-1 receptor in the development of bone cancer pain. Walker 256 mammary gland carcinoma cells were implanted into the intramedullary space of the right tibia of Sprague-Dawley rats to induce ongoing bone cancer-related pain behaviors; our findings indicated that, on days 7, 10, 14, and 21 after operation, the expression of sigma-1 receptor in the spinal cord was higher in BCP rats compared to the sham rats. Furthermore, intrathecal injection of 120 nmol of sigma-1 receptor antagonist BD1047 on days 5, 6, and 7 after operation attenuated mechanical allodynia as well as the associated induction of c-Fos and activation of microglial cells, NR1, and the subsequent Ca(2+)-dependent signals of BCP rats. These results suggest that sigma-1 receptor is involved in the development of bone cancer pain and that targeting sigma-1 receptor may be a new strategy for the treatment of bone cancer pain.

    Although estrous cycle has been reported to influence antiociceptive effect of morphine in several pain conditions, its effect on cancer pain is not well established. We investigated the effect of estrogen on morphine antinociception using a bone cancer pain model and compared its potency with that of oxycodone. Female mice were ovariectomized (OVX) for preparation of a femur bone cancer pain (FBC) model. β-estradiol was subcutaneously (s.c.) administered and antinociceptive effects of opioids was assessed using the von Frey monofilament test. Although morphine (5-20mg/kg, s.c.) did have significant antinociceptive effects in the FBC-OVX group, its effects in the FBC-OVX+β-estradiol (OVX+E) group was limited. Oxycodone (1-5mg/kg, s.c.) exhibited significant effects in both groups. Expression changes in opioid-related genes (μ-, κ-, δ-opioid receptors, prodynorphin, proenkephalin, proopiomelanocortin) in the spinal and supraspinal sites were examined among the sham-OVX, sham-OVX+E, FBC-OVX, and FBC-OVX+E groups by in situ hybridization. These studies detected a significant increase in prodynorphin in the spinal dorsal horn of the FBC-OVX+E group. Spinal injection of a dynorphin-A antibody to FBC-OVX+E mice restored antinociception of morphine. In conclusion, we detected a differential effect of estrogen on morphine- and oxycodone-induced antinociception in a female FBC model. The effect of morphine was limited with estrogen exposure, which may be due to estrogen- and pain-mediated spinal expression of dynorphin-A.

    In this study, we examined the involvement of chemokine monocyte chemoattractant protein-1 (MCP-1) in the spinal cord of a rat model of cancer-induced bone pain (CIBP). In this model, CIBP was established by an intramedullary injection of Walker 256 cells into the tibia of rats. We observed a significant increase in expression levels of MCP-1 and its receptor CCR2 in the spinal cord of CIBP rats. Furthermore, the intrathecal administration of an anti-MCP-1 neutralizing antibody attenuated the mechanical allodynia established in CIBP rats. Likewise, an intrathecal injection of exogenous recombinant MCP-1 induced a striking mechanical allodynia in naïve rats. These results suggest that increases in spinal MCP-1 and CCR2 expression are involved in the development of mechanical allodynia associated with bone cancer rats.

    Primary and metastatic cancers that affect bones are frequently associated with severe and intractable pain. The mechanisms underlying the development of bone cancer pain are largely unknown. In the present study, we investigated whether inhibition of KCNQ/M (Kv7) potassium channels in the spinal cord contributes to the development of bone cancer pain via sensitization of dorsal horn wide dynamic range (WDR) neurons. Using a rat model of bone cancer pain based on intratibial injection of MRMT-1 tumor cells, we observed a significant increase in C-fiber responses of dorsal horn WDR neurons in the MRMT-1 injected rats, indicating sensitization of spinal WDR neurons in bone cancer rats. Furthermore, we discovered that blockade of KCNQ/M channels in the spinal cord by local administration of XE-991, a specific KCNQ/M channel blocker, caused a robust increase in excitability of dorsal horn WDR neurons, while, producing obvious pain hypersensitivity in normal rats. On the contrary, activation of spinal KCNQ/M channels by retigabine, a selective KCNQ/M channel opener, not only inhibited the bone cancer‑induced hyperexcitability of dorsal horn WDR neurons, but also alleviated mechanical allodynia and thermal hyperalgesia in the bone cancer rats, while all of these effects of retigabine could be blocked by KCNQ/M-channel antagonist XE-991. All things considered, these results suggest that suppression of KCNQ/M channels in the spinal cord likely contributes to the development of bone cancer pain via sensitization of dorsal horn WDR neurons in rats following tumor cell inoculation.

Methods A 12-week prospective study was carried out in 25 opioid-naïve MBD patients. Patients initially received twice-daily doses of tapentadol PR 50 mg. Doses were then managed to maintain adequate relief or dose-limiting toxicity. The following parameters were recorded at weekly intervals for 4 weeks, and then at weeks 8 and 12: pain, opioid-related adverse effects, use of other analgesics, DN4 (Douleur Neuropathique 4) score. Quality of life (SF-36 [36-item short-form health survey]) was measured at baseline and at final evaluation. Results Of 25 patients, 22 completed the study. Pain intensity significantly decreased from baseline to all the week intervals (P<0.01). Quality of life significantly improved with respect to all SF-36 subscale parameters (P<0.01), and so did both the physical and mental status (P<0.01). Tapentadol PR significantly reduced DN4 mean value (P<0.01) and the number of patients with neuropathic component (DN4 ≥4) (P<0.01). After 8 weeks of treatment, all patients were negative for the DN4 score. Tapentadol PR was well tolerated, and the use of other analgesics was reduced during the study period. Conclusion Tapentadol PR started in doses of 100 mg/day was effective and well tolerated in opioid-naïve MBD patients with moderate-to-severe pain. Tapentadol PR can be considered a first-choice opioid in cancer patients suffering from mixed pain with a neuropathic component. PMID:26064064

  16. Functional upregulation of nav1.8 sodium channels on the membrane of dorsal root Ganglia neurons contributes to the development of cancer-induced bone pain.

    Directory of Open Access Journals (Sweden)

    Xiao-Dan Liu

    Full Text Available We have previously reported that enhanced excitability of dorsal root ganglia (DRG neurons contributes to the development of bone cancer pain, which severely decreases the quality of life of cancer patients. Nav1.8, a tetrodotoxin-resistant (TTX-R sodium channel, contributes most of the sodium current underlying the action potential upstroke and accounts for most of the current in later spikes in a train. We speculate that the Nav1.8 sodium channel is a potential candidate responsible for the enhanced excitability of DRG neurons in rats with bone cancer pain. Here, using electrophysiology, Western blot and behavior assays, we documented that the current density of TTX-R sodium channels, especially the Nav1.8 channel, increased significantly in DRG neurons of rats with cancer-induced bone pain. This increase may be due to an increased expression of Nav1.8 on the membrane of DRG neurons. Accordantly, blockade of Nav1.8 sodium channels by its selective blocker A-803467 significantly alleviated the cancer-induced mechanical allodynia and thermal hyperalgesia in rats. Taken together, these results suggest that functional upregulation of Nav1.8 channels on the membrane of DRG neurons contributes to the development of cancer-induced bone pain.

    Cancer pain management is a challenge for which Chinese herbal medicine might be useful. To study the spinal mechanisms of the Chinese medicated gel Long-Teng-Tong-Luo (LTTL), a 7-herb compound, on bone cancer pain, a bone cancer pain model was made by inoculating the tibias of female rats with Walker 256 cells. LTTL gel or inert gel, 0.5 g/cm(2)/d, was applied to the skin of tumor-bearing tibias for 21 days beginning a day after the inoculation. Mechanical threshold and paw withdrawal latency to thermal stimulation was measured. Transient receptor potential (TRP) cation channels in lumbar dorsal root ganglia (DRG) were immunostained and counted, and lumbar spinal cord interleukin-17A (IL-17A) was measured with real-time polymerase chain reaction and enzyme-linked immunosorbent assay. TRP antagonists and interleukin (IL)-17A antibodies were intrathecally administered to determine their effects on bone cancer pain. The gel significantly (P gel inhibits cancer pain, and this might be accounted for by the decrease in expression of DRG TRP channels and spinal astrocyte IL-17A.

    Purpose: This is the first Brazilian study intended to evaluate the response of pain relief with radiotherapy in three different fractionation and the clinical differences in managing pain in patients with painful bone metastases. Methods: Prospective study of patients with painful bone metastases referred to the Radiotherapy Sector of the Hospital de Cancer de Barretos for pain-relieving radiotherapy between March and December 2010. It is known that radiotherapy seems to alter the activation of osteoclast-mediated bone resorption, relieving pain in cases of painful bone metastases. Patients were assessed in relation to the status of pain intensity before and after the initiation of radiotherapy. Either a single fraction of 8Gy, five fractions of 4Gy or ten fractions of 3Gy were given. A visual analog scale (VAS) was applied by doctors, nurses and nursing technicians to assess pain intensity at each session of radiotherapy, and follow-up at 8, 30 and 90 days from the end of treatment. Results: We evaluated 92 consecutive patients, 48 male and 44 female, with a median age of 58 years. We found that 14% of patients referred from the Palliative Care or Clinical Oncology sectors need better pharmacological analgesia due to severe pain, compared with 40.5% of patients from the other sectors (p = 0.004). We also found that the onset of pain relief to patients receiving 10 fractions of 300cGy analgesia without changing the pre-radiotherapy analgesia occurred with significance after the fifth fraction. Improvement in pain experienced within 90 days of follow-up was found in eighty percent of patients, independent of fractionated radiotherapy, site of metastases and the clinical condition of the patient. Discussion/Conclusion: The Palliative Care and Clinical Oncology sectors expressed greater concern in regards to analgesia for the patient with painful bone metastases. Radiotherapy is an effective pain-relieving treatment in different fractionation studied, even though the

    Cancer induced bone pain is a very complicated clinical pain states that has proven difficult to be treated effectively due to poorly understand of underlying mechanism, but bone cancer pain (BCP) seems to be enhanced by a state of spinal sensitization. In the present study, we showed that carcinoma tibia implantation induced notable pain sensitization and up-regulation of G-protein-coupled estrogen receptor (GPR30) in the spinal cord of rats which was reversed by GPR30 knockdown. Further studies indicated that upregulation of GPR30 induced by cancer implantation resulted in a select loss of γ-aminobutyric acid-ergic (GABAergic) neurons and functionally diminished the inhibitory transmission due to reduce expression of the vesicular GABA transporter (VGAT). GPR30 contributed to spinal cord disinhibition by diminishing the inhibitory transmission via upregulation of α1 subunit and downregulation of γ2 subunits. GPR30 also facilitated excitatory transmission by promoting functional up-regulation of the calcium/calmodulin-dependent protein kinase II α (CaMKII α) in glutamatergic neurons and increasing the clustering of the glutamate receptor subunit 1 (GluR1) subunit to excitatory synapse.Taken together, GPR30 contributed to the development of BCP by both facilitating excitatory transmission and inhibiting inhibitory transmission in the spinal cord. Our findings provide the new spinal disinhibition and sensitivity mechanisms underlying the development of bone cancer pain.

  1. Pain management in cancer cervix

    Palat Gayatri

    2005-01-01

    Full Text Available Cancer of the cervix uteri is a common cause of pain among women. On the physical realm, the cancer may cause somatic [soft tissue and bone], visceral and neuropathic pain [lumbosacral plexopathy]. Radiotherapy and chemotherapy may cause neuropathy too. Psychological, social and cultural factors modify the pain. Evaluation of the individual type of pain and a patient-centred approach are fundamental requirements for rational management. Disease modifying treatment like radiotherapy and chemotherapy must be considered when applicable. Pain control is usually achieved by the use of WHO three-step ladder, remembering that possible association of renal dysfunction would necessitate caution in the use of NSAIDs and opioids. Side effects must be anticipated, prevented when possible, and aggressively treated; nausea and vomiting may already be present, and constipation can worsen pain when there is a pelvic mass. Pain emergencies can be treated by quick titration with intravenous morphine bolus doses. Neuropathic pain may warrant the use of usual adjuvants, with particular reference to cortico-steroids and the NMDA antagonist, ketamine. In intractable pain, many neurolytic procedures are tried, but a solid evidence base to justify their use is lacking. Continuous epidural analgesia with local anaesthetic and opioid may be needed when drug therapy fails, and desperate situations may warrant interventions such as neurolysis. Such physical measures for pain relief must be combined with psychosocial support and adequate explanations to the patient and the family.

    Background Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled “Orofacial Pain and Cancer” (Dolor Orofacial y Cancer) given at the VI Simposio International “Advances in Oral Cancer” on the 22 July, 2016 in Donostia. Material and Methods We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. Results There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. Conclusions The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years. Key words:Pain, orofacial, facial, cancer. PMID:27694791

    Cancer-induced bone pain (CIBP) is a common clinical problem in breast cancer patients with bone metastasis. Recent studies shows chemokines are novel targets for treatment of CIBP. In this study, we intra-tibial inoculated with Walker 256 rat mammary gland carcinoma cells into rat bone to established metastatic breast cancer. Then we measured the expression of CXCL10 in the spinal cord of metastatic bone cancer rats, investigated the role of CXCL10 in the development of CIBP, and the underlying mechanism. Results revealed that after intra-tibial inoculation with Walker 256 cells, rats showed up-regulation of CXCL10 and its receptor CXCR3 in the spinal cord. Interestingly, intrathecally injection of recombinant CXCL10 protein induced mechanical allodynia in naïve rats. Blocking the function of CXCL10/CXCR3 pathway via anti-CXCL10 antibody or CXCR3 antagonist prevented the development of CIBP and microglial activation. Moreover, CXCL10-induced mechanical allodynia was rescued by minocycline treatment during the late-stage of CIBP, days 10-14. The regulation of CXCL10 expression involved microglial activation in a manner of autocrine positive feedback. These results suggest that CXCL10 may be a necessary algogenic molecule, especially in the development of CIBP. Its function was partly mediated via spinal microglial activation. This study provides a novel insight into the biological function of chemokine CXCL10 in the molecular mechanism underlying cancer pain. It also provides new target for clinical treatment of metastatic breast cancer-induced bone pain in future.

    Cancer-induced bone pain (CIBP) is a challenging medical problem that considerably influences cancer patients' quality of life. Currently, few treatments have been developed to conquer CIBP because of a poor understanding of the potential mechanisms. Our previous work has proved that spinal RANTES (a major ligand for CCR5) was involved in the maintenance of CIBP. In this study, we attempted to investigate whether spinal CCR5 and its downstream PKCγ pathway is involved in the maintenance of CIBP. Inoculation of Walker 256 cells into the tibia could induce a marked mechanical allodynia with concomitant upregulation of spinal CCR5 and p-PKCγ expression from day 6 to day 15 after inoculation. Spinal CCR5 was prominently expressed in microglia, and mechanical allodynia was attenuated by intrathecal injection of DAPTA (a specific antagonist of CCR5) with downregulation of spinal CCR5 and p-PKCγ expression levels at day 15 in inoculated rats. Pre-intrathecal injection of RANTES could reverse the anti-allodynia effects of DAPTA. Intrathecal administration of GF109203X (an inhibitor of PKC) could alleviate mechanical allodynia as well as decrease of spinal p-PKCγ expression level, but no influence on spinal CCR5 level. Our findings suggest that CCR5/PKCγ signaling pathway in microglia may contribute to the maintenance of CIBP in rats.

    The activation of MAPK pathways in spinal cord and subsequent production of proinflammatory cytokines in glial cells contribute to the development of spinal central sensitization, the basic mechanism underlying bone cancer pain (BCP). Our previous study showed that spinal CXCL12 from astrocytes mediates BCP generation by binding to CXCR4 in both astrocyters and microglia. Here, we verified that CXCL12/CXCR4 signaling contributed to BCP through a MAPK-mediated mechanism. In naïve rats, a single intrathecal administration of CXCL12 considerably induced pain hyperalgesia and phosphorylation expression of spinal MAPK members (including extracellular signal-regulated kinase, p38, and c-Jun N-terminal kinase), which could be partially prevented by pre-treatment with CXCR4 inhibitor AMD3100. This CXCL12-induced hyperalgesia was also reduced by MAPK inhibitors. In bone cancer rats, tumor cell inoculation into the tibial cavity caused prominent and persistent pain hyperalgesia, and associated with up-regulation of CXCL12 and CXCR4, activation of glial cells, phosphorylation of MAPKs, and production of proinflammatory cytokines in the spinal cord. These tumor cell inoculation-induced behavioral and neurochemical alterations were all suppressed by blocking CXCL12/CXCR4 signaling or MAPK pathways. Taken together, these results demonstrate that spinal MAPK pathways mediated CXCL12/CXCR4-induced pain hypersensitivity in bone cancer rats, which could be druggable targets for alleviating BCP and glia-derived neuroinflammation. Following tumor cell inoculation, chemokine CXCL12 from astrocytes spreads around the spinal environment, resulting in functional activation of CXCR4-expressing astrocytes and microglia. Once glia are activated, they may initiate MAPK (mitogen-activated protein kinase) pathways, and subsequently produce proinflammatory cytokines and chemokines. Among them, CXCL12 could reinforce the astrocytic and microglial activation in autocrine and paracrine manners

    Sixty-five percent of patients with advanced cancer present bone metastases and most of them present a rather slow clinical course characterized by pain, mobility deficiencies and skeletal complications such as fractures and spinal cord compression. Metastatic involvement of the bone is one of the most frequent causes of pain in cancer patients and represents one of the firs signs of widespread neoplastic disease. The pain may originate directly from the plastic disease. The pain may originate directly from the bone, from nerve root compression or from muscle spasms in the area of the lesions. The mechanism of metastatic bone pain is mainly somatic (nociceptive) even though, in some cases, neuropathic and visceral stimulations may overlap. The conventional symptomatic treatment of metastatic bone pain requires the use of multidisciplinary therapies such as radiotherapy in association with systemic treatment (hormonotherapy, chemotherapy, radioisotopes) with the support of analgesic therapy. Recently, studies have indicated the use of bisphosphonates in the treatment of pain and in the prevention of skeletal complications in patients with metastatic bone disease. In some patients pharmacological treatment, radiotherapy, radioisotopes administered alone or in association are not able to manage pain adequately. The role of neuroinvasive techniques in treating metastatic bone pain is debated. The clinical conditions of the patient, his life expectancy and quality of life must guide the physician in the choice of the best possible therapy.

    Objective Our previous study showed that tumor tissue-derived formaldehyde at low concentrations plays an impoaant role in bone cancer pain through activating transient receptor potential vanilloid subfamily member 1 (TRPV1).The present study further explored whether this tumor tissue-derived endogenous formaldehyde regulates TRPV1 expression in a rat model of bone cancer pain,and if so,what the possible signal pathways are during the development of this type of pain.Methods A rat model of bone cancer pain was established by injecting living MRMT-1 tumor cells into the tibia.The formaldehyde levels were determined by high performance liquid chromatography,and the expression of TRPV1 was examined with Western blot and RT-PCR.In primary cultured dorsal root ganglion (DRG) neurons,the expression of TRPV1 was assessed after treatment with 100 μmol/L formaldehyde with or without pre-addition of PD98059 [an inhibitor for extracellular signal-regulated kinase],SB203580 (a p38 inhibitor),SP600125 [an inhibitor for c-Jun Nterminal kinase],BIM [a protein kinase C (PKC) inhibitor] or LY294002 [a phosphatidylinositol 3-kinase (PI3K) inhibitor].Results In the rat model of bone cancer pain,formaldehyde concentration increased in blood plasma,bone marrow and the spinal cord.TRPV1 protein expression was also increased in the DRG.In primary cultured DRG neurons,100μmol/L formaldehyde significantly increased the TRPV1 expression level.Pre-incubation with PD98059,SB203580,SP600125 or LY294002,but not BIM,inhibited the formaldehyde-induced increase of TRPV1 expression.Conclusion Formaldehyde at a very low concentration up-regulates TRPV1 expression through mitogen-activated protein kinase and PI3K,but not PKC,signaling pathways.These results further support our previous finding that TRPV1 in peripheral afferents plays a role in bone cancer pain.

    Full Text Available Abstract Background The neuroinflammatory responses in the spinal cord following bone cancer development have been shown to play an important role in cancer-induced bone pain (CIBP. Lipoxins (LXs, endogenous lipoxygenase-derived eicosanoids, represent a unique class of lipid mediators that possess a wide spectrum of anti-inflammatory and pro-resolving actions. In this study, we investigated the effects of intrathecal injection with lipoxin and related analogues on CIBP in rats. Methods The CIBP model was induced by intra-tibia inoculation of Walker 256 mammary gland carcinoma cells. Mechanical thresholds were determined by measuring the paw withdrawal threshold to probing with a series of calibrated von Frey filaments. Lipoxins and analogues were administered by intrathecal (i.t. or intravenous (i.v. injection. The protein level of LXA4 receptor (ALX was tested by western blot. The localization of lipoxin receptor in spinal cord was assessed by fluorescent immunohistochemistry. Real-time PCR was carried out for detecting the expression of pro-inflammatory cytokines. Results Our results demonstrated that: 1 i.t. injection with the same dose (0.3 nmol of lipoxin A4 (LXA4, lipoxin B4 (LXB4 or aspirin-triggered-15-epi-lipoxin A4 (ATL could alleviate the mechanical allodynia in CIBP on day 7 after surgery. ATL showed a longer effect than the others and the effect lasted for 6 hours. ATL administered through i.v. injection could also attenuate the allodynia in cancer rats. 2 The results from western blot indicate that there is no difference in the expression of ALX among the naive, sham or cancer groups. 3 Immunohistochemistry showed that the lipoxin receptor (ALX-like immunoreactive substance was distributed in the spinal cord, mainly co-localized with astrocytes, rarely co-localized with neurons, and never co-localized with microglia. 4 Real-time PCR analysis revealed that, compared with vehicle, i.t. injection with ATL could significantly

Effectiveness was evaluated by visual analog scale (VAS) and daily morphine dose with a follow-up of 6-months. Complications were also recorded. Mean VAS score and morphine dose pre-procedure were 7.4 ± 1.6 (range, 5-10) and 47.7 ± 30.1 mg (range, 20-120 mg), respectively. Technical success and pain relief were achieved in all patients. Mean VAS scores and daily morphine doses post-procedure were as follows: 48 h, 1.7 ± 1.2 (p < 0.001) and 29.6 ± 16.1 mg (p = 0.003); 7 days, 1.9 ± 1.7 (p < 0.001) and 16.1 ± 12.0 mg (p < 0.001); 1 month, 1.5 ± 0.9 (p < 0.001) and 10.8 ± 10.9 (p < 0.001); 3 months, 0.9 ± 0.7 (p < 0.001) and 8.4 ± 9.2 mg (p < 0.001); and 6 months, 1.2 ± 0.8 (p < 0.001) and 9.2 ± 12.3 mg (p < 0.001). Complications were observed in eight patients (28 %); among these, major complications were reported in two (7.7 %) patients, one with local infection and the other with a bone fracture. The minor complication rate was 23.1 % (6/26). MWA combination with osteoplasty appeared to be an effective and safe treatment for lung cancer patients with painful extraspinal bone metastases.

    We have utilized 89Sr as palliative treatment for bone pain secondary to metastatic cancer in the skeleton of over 200 patients. The best results have been in patients with carcinoma of the prostate (80% response rate) and breast (89%). Results in a small number of patients with a variety of other cell types were not nearly as encouraging. Strontium-89 provides excellent palliation in the management of bone pain secondary to prostate and breast carcinoma.

    Bone metastasis occurs as a result of a complex pathophysiologic process between host and tumor cells leading to cellular invasion, migration adhesion, and stimulation of osteoclastic and osteoblastic activity. Several sequences occur as a result of osseous metastases and resulting bone pain can lead to significant debilitation. Pain associated with osseous metastasis is thought to be distinct from neuropathic or inflammatory pain. Several mechanisms, such as invasion of tumor cells, spinal cord astrogliosis,and sensitization of nervous system, have been postulated to cause pain. Pharmaceutical therapy of bone pain includes nonsteroidal analgesics and opiates. These drags are associated with side effects, and tolerance to these agents necessitates treatment with other modalities. Bisphosphonates act by inhibiting osteoclast-mediated resorption and have been increasingly used in treatment of painful bone metastasis. While external beam radiation therapy remains the mainstay of pain palliation of solitary lesions, bone-seeking radiopharmaceuticals have entered the therapeutic armamentarium for the treatment of multiple painful osseous lesions. 32p has been used for over 3 decades in the treatment of multiple osseous metastases. The myelosuppression caused by this agent has led to the development of other bone-seeking radiopharmaceuticals, including 89SrCl, and 153Sm-ethylenediaminetetramethylene phosphonic acid (153Sm-EDTMP). 89Sr is a bone-seeking radionuclide, whereas 153Sm-EDTMP is a bone-seeking tetraphosphonate; both have been approved by the Food and Drug Administration for the treatment of painful osseous metastases. While both agents have been shown to have efficacy in the treatment of painful osseous metastases from prostate cancer, they may also have utility in the treatment of painful osseous metastases from breast cancer and perhaps from non-small cell lung cancer. This article illustrates the salient features of these radiopharmaceuticals, including the

    Managing cancer-related chronic pain is challenging to health care professionals as well as cancer patients and survivors. The management of cancer-related pain has largely consisted of pharmacological treatments, which has caused researchers to focus on neurotransmitter activity as a mediator of patients' perception of pain rather than the electrical activity during neurobiological processes of cancer-related pain. Consequently, brain-based pain treatment has focused mainly on neurotransmitters and not electrical neuromodulation. Neuroimaging research has revealed that brain activity is associated with patients' perceptions of symptoms across various diagnoses. The brain modulates internally generated neural activity and adjusts perceptions according to sensory input from the peripheral nervous system. Cancer-related pain may result not only from changes in the peripheral nervous system but also from changes in cortical activity over time. Thus, cortical reorganization by way of the brain's natural, plastic ability (neuroplasticity) may be used to manage pain symptoms. Physical and psychological distress could be modulated by giving patients tools to regulate neural activity in symptom-specific regions of interest. Initial research in nononcology populations suggests that encouraging neuroplasticity through a learning paradigm can be a useful technique to help treat chronic pain. Here we review evidence that indicates a measurable link between brain activity and patient-reported psychological and physical distress. We also summarize findings regarding both the neuroelectrical and neuroanatomical experience of symptoms, review research examining the mechanisms of the brain's ability to modify its own activity, and propose a brain-computer interface as a learning paradigm to augment neuroplasticity for pain management.

    Although, the use of technetium scintigraphy in the assessment of anterior knee pain has been described, no reference has been made to the scintigraphic appearances of painful bipartite patella. We report the scintigraphic-appearances of painful bipartite patella in 25-year-old man a 2 1/2 years history of unexplained patellar pain. Painful bipartite patella is a rare cause of chronic post-traumatic patellar pain. Bone scintigraphy, by demonstrating increased uptake by the painful accessory bipartite fragment, appears to be an imaging method of choice in the diagnosis of this condition. (orig./MG)

    2017-01-01

    Lung cancer is one of the four most prevalent cancers worldwide. Comprehensive patient care includes not only adherence to clinical guidelines to control and when possible cure the disease but also appropriate symptom control. Pain is one of the most prevalent symptoms in patients diagnosed with lung cancer; it can arise from local invasion of chest structures or metastatic disease invading bones, nerves, or other anatomical structures potentially painful. Pain can also be a consequence of therapeutic approaches like surgery, chemotherapy, or radiotherapy. Conventional medical management of cancer pain includes prescription of opioids and coadjuvants at doses sufficient to control the symptoms without causing severe drug effects. When an adequate pharmacological medical management fails to provide satisfactory analgesia or when it causes limiting side effects, interventional cancer pain techniques may be considered. Interventional pain management is devoted to the use of invasive techniques such as joint injections, nerve blocks and/or neurolysis, neuromodulation, and cement augmentation techniques to provide diagnosis and treatment of pain syndromes resistant to conventional medical management. Advantages of interventional approaches include better analgesic outcomes without experiencing drug-related side effects and potential for opioid reduction thus avoiding central side effects. This review will describe various pain syndromes frequently described in lung cancer patients and those interventional techniques potentially indicated for those cases. PMID:28261561

    The purpose of this study was to evaluate the efficacy and safety of {sup 177}Lu-EDTMP for pain palliation in patients with bone metastases from castration-resistant prostate and breast cancer. The secondary objective was to compare low-dose and high-dose {sup 177}Lu-EDTMP in bone pain palliation. Included in the study were 44 patients with documented breast carcinoma (12 patients; age 47 ± 13 years) or castration-resistant prostate carcinoma (32 patients; age 66 ± 9 years) and skeletal metastases. Patients were randomized into two equal groups treated with {sup 177}Lu-EDTMP intravenously at a dose of 1,295 MBq (group A) or 2,590 MBq (group B). Pain palliation was evaluated using a visual analogue score (VAS), analgesic score (AS) and Karnofsky performance score (KPS) up to 16 weeks. Toxicity was assessed in terms of haematological and renal parameters. The overall response rate (in all 44 patients) was 86 %. Complete, partial and minimal responses were seen in 6 patients (13 %), 21 patients (48 %) and 11 patients (25 %), respectively. A favourable response was seen in 27 patients (84 %) with prostate cancer and in 11 patients (92 %) with breast cancer. There was a progressive decrease in the VAS from baseline up to 4 weeks (p < 0.05). Also, AS decreased significantly from 1.8 ± 0.7 to 1.2 ± 0.9 (p < 0.0001). There was an improvement in quality of life of the patients as reflected by an increase in mean KPS from 56 ± 5 to 75 ± 7 (p < 0.0001). The overall response rate in group A was 77 % compared to 95 % in group B (p = 0.188). There was a significant decrease in VAS and AS accompanied by an increase in KPS in both groups. Nonserious haematological toxicity (grade I/II) was observed in 15 patients (34 %) and serious toxicity (grade III/IV) occurred in 10 patients (23 %). There was no statistically significant difference in haematological toxicity between the groups. {sup 177}Lu-EDTMP was found to be a safe and effective radiopharmaceutical for bone pain

    In men, prostate cancer is the most common non-cutaneous malignancy and the second most common cause of cancer death. Skeletal complications occur at various points during the disease course, either due to bone metastases directly, or as an unintended consequence of androgen deprivation therapy (ADT). Bone metastases are associated with pathologic fractures, spinal cord compression, and bone pain and can require narcotics or palliative radiation for pain relief. ADT results in bone loss and fragility fractures. This review describes the biology of bone metastases, skeletal morbidity, and recent advances in bone-targeted therapies to prevent skeletal complications of prostate cancer.

    The bone is the most common target organ of cancer metastasis. Bone metastasis leads to considerable morbidity due to skeletal-related events (SREs). These include bone pain, hypercalcemia, pathologic frac-tures, and compression of the spinal cord. Cancers such as those of the lung, breast, prostate, and kidney are more likely to cause SREs than other cancer types. Additionaly, some blood cancers, including multiple myeloma and lymphoma, frequently cause SREs. In this article, we review the conventional therapies for metastatic bone disease, including drug therapy, radiotherapy, and surgery. Among osteoclast-targeting agents, bisphosphonates and nuclear factor kappa-B ligand inhibitors are the most widely used agents to prevent cancer-related bone loss. Unsealed radioisotopes are also considered promising in cancer therapy. Currently, iodine-131, strontium-89, and radium-223 are available for the treatment of bone metastasis. However, the treatments for blood cancers with SREs are diferent from those of other cancers. In those cases, new classes of agents including proteasome inhibitors, immunomodulatory drugs, monoclonal anti-bodies, and histone deacetylase inhibitors have shown remarkable eficacy. We also discuss the potential development of new therapies for these diseases.

    Full Text Available A majority of pancreatic cancer patients present with pain at the time of diagnosis. Pain management can be challenging in light of the aggressive nature of this cancer. Apart from conventional pharmacotherapy, timely treatment with neurolytic celiac plexus block (NCPB has been shown to be of benefit. NCPB has demonstrated efficacious pain control in high quality studies with analgesic effects lasting one to two months. NCPB has also shown to decrease the requirements of narcotics, and thus decrease opioid related side effects. Another option for the control of moderate to severe pain is intrathecal therapy (IT. Delivery of analgesic medications intrathecally allows for lower dosages of medications and thus reduced toxicity. Both of the above mentioned interventional procedures have been shown to have low complication rates, and be safe and effective. Ultimately, comprehensive pancreatic cancer pain management necessitates understanding of pain mechanisms and delivery of sequential validated therapeutic interventions within a multidisciplinary patient care model.

    Bone metastasis is a common sequelae of solid malignant tumors such as prostate, breast, lung, and renal cancers, which can lead to various complications, including fractures, hypercalcemia, and bone pain, as well as reduced performance status and quality of life. It occurs as a result of a complex pathophysiologic process between host and tumor cells leading to cellular invasion, migration adhesion, and stimulation of osteoclastic and osteoblastic activity. Several sequelae occur as a result of osseous metastases and resulting bone pain can lead to significant debilitation. A multidisciplinary approach is usually required not only to address the etiology of the pain and is complicating factors but also to treat the patient appropriately. Pharmaceutical therapy of bone pain, includes non-steroidal analgesics, opiates, steroids, hormones, bisphosphonates, and chemotherapy. While external beam radiation therapy remains the mainstay of pain palliation of a solitary lesions, bone seeking radiopharmaceuticals have entered the therapeutic armamentarium for the treatment of multiple painful osseous lesion. {sup 32}P, {sup 89}SrCl, {sup 153}Sm-EDTMP, {sup 188}Re/{sup 186}Re-HEDP, and {sup 177}Lu-EDTMP can be used to treat painful osseous metastases. These various radiopharmaceuticals have shown good efficacy in relieving bone pain secondary to bone metastasis. This systemic from of metabolic radiotherapy is simple to administer and complements other treatment options. This has been associated with improved mobility in many patients, reduced dependence on narcotic and non-narcotic analgesics, improved performance status and quality of life, and in some studies, improved survival. All of these agents, although comprising different physical and chemical characteristics, offer certain advantages in that they are simple to administer, are well tolerated by the patient if used appropriately, and can be used alone or in combination with the other forms of treatment.

    We evaluated the pain response and daily discomfort in patients suffering from a borderline degree of bone pain due to breast or lung cancer bone metastases, who had undergone early palliative radionuclide treatment. The results were compared with those from patients who had received standard analgesic therapy. Twenty-one patients (65.7 ± 3 years; 17 women) with metastatic bone cancer underwent samarium-153 (Sm-153) ethylene diamine tetramethylene phosphonate (EDTMP) administration (group A) and 18 patients (64.3 ± 8 years; 16 women)continued to receive standard analgesics (group B; control group). The patients kept a daily pain diary assessing both their discomfort and the pain at specific sites by means of a visual analog scale, rating from 0 (no discomfort–no pain)to 10 (worst discomfort–pain). These diaries were reviewed weekly for 2 months and three physicians rated the pain response on a scale from -2 (considerable deterioration) to +2 (considerable improvement). Baseline characteristics were similar in both groups. The reduction of total discomfort and of bone pain in group A was significantly greater compared to group B (p < 0.0001). A significant improvement of clinical conditions was observed in group A, where the physician rate changed from -1 to 1, compared to group B in which the rate changed from -1 to 0. Sm-153 EDTMP therapy can be considered for patients with bone pain from breast and lung cancer in advance, i.e.,before the establishment of severe pain syndrome.

    Bone cancer pain (BCP) is one of the most difficult and intractable tasks for pain management, which is associated with spinal 'neuron-astrocytic' activation. The activation of the c-Jun N-terminal kinase (JNK)/chemokine (C-C motif) ligand (CCL2) signaling pathway has been reported to be critical for neuropathic pain. Rolipram (ROL), a selective phosphodiesterase 4 inhibitor, possesses potent anti-inflammatory and anti-nociceptive activities. The present study aimed to investigate whether the intrathecal administration of ROL has an analgesic effect on BCP in rats, and to assess whether the inhibition of spinal JNK/CCL2 pathway and astrocytic activation are involved in the analgesic effects of ROL. The analgesic effects of ROL were evaluated using the Von Frey and Hargreaves tests. Immunofluorescence staining was used to determine the number of c-Fos immunoreactive neurons, and the expression of spinal astrocytes and microglial activation on day 14 after tumor cell inoculation. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of pro-inflammatory cytokines [interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α] and chemokines (CCL2), and western blot analysis was then used to examine the spinal phosphodiesterase 4 (PDE4), ionized calcium binding adapter molecule-1 (IBA-1) and JNK levels on day 14 after tumor cell inoculation. The results revealed that ROL exerted a short-term analgesic effect in a dose-dependent manner, and consecutive daily injections of ROL exerted continuous analgesic effects. In addition, spinal 'neuron-astrocytic' activation was suppressed and was associated with the downregulation of spinal IL-1β, IL-6 and TNF-α expression, and the inhibition of PDE4B and JNK levels in the spine was also observed. In addition, the level of CCL2 was decreased in the rats with BCP. The JNK inhibitor, SP600125, decreased CCL2 expression and attenuated pain behavior. Following co-treatment with ROL and SP600125, no significant

    Objective To investigate the effect of intraperitoneal injection of thalidomide on pain behaviors in a mouse model of bone cancer pain. Methods 36 male C3H/HeJ mice were divided randomly into tumor group (n= 18) and sham group (n= 18) ,six mice from each group were chosen to examine the time course of changes in behavior after tumor cells inoculated to the bone. 2 × 105 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors. The sham group was inoculated by α-MEM without any cells. On the day before inoculation,the tumor mice were divided randomly into tumor + thalidomide group and tumor + vehicle group. The sham group mice were further divided randomly into sham + thalidomide group and sham + vehicle group. Pain ethology indexes such as paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were observed on 1 d before inoculation and on 3 d ,5 d ,7 d, 10 d, 14 d after inoculation. Results ( 1 ) At day 7 after the operation, compared with sham mice ( 1. 70 ± 0. 33 ) g, PWMT of tumor mice decreased to ( 1.07 ± 0. 30) g (P < 0. 05 ).

    The public and healthcare professionals have become increasingly aware and accepting of the benefit in physical, psychological, social, and spiritual support for patients with cancer. Patients with cancer often seek nonpharmacologic interventions to complement conventional care and decrease the pain associated with cancer and its treatment. Most often referred to as complementary and alternative medicine (CAM), these supportive therapies consist of a heterogeneous group of modalities used as adjuncts to allopathic health care. Biofield therapies are CAM modalities that involve the direction of healing energy through the hands to facilitate well-being by modifying the energy field of the body. This critical review of studies of biofield therapies emphasizes research using these modalities to decrease pain in patients with cancer. Although the therapies have demonstrated clinical efficacy, additional research is warranted. Oncology nurses should familiarize themselves with biofield therapies so they can offer informed recommendations to patients with cancer experiencing pain.

    Full Text Available Cancer pain is multifactorial and complex. The impact of cancer pain is devastating, with increased morbidity and poor quality of life, if not treated adequately. Cancer pain management is a challenging task both due to disease process as well as a consequence of treatment-related side-effects. Optimization of analgesia with oral opioids, adjuvant analgesics, and advanced pain management techniques is the key to success for cancer pain. Early access of oral opioid and interventional pain management techniques can overcome the barriers of cancer pain, with improved quality of life. With timely and proper anticancer therapy, opioids, nerve blocks, and other non-invasive techniques like psychosocial care, satisfactory pain relief can be achieved in most of the patients. Although the WHO Analgesic Ladder is effective for more than 80% cancer pain, addition of appropriate adjuvant drugs along with early intervention is needed for improved Quality of Life. Effective cancer pain treatment requires a holistic approach with timely assessment, measurement of pain, pathophysiology involved in causing particular type of pain, and understanding of drugs to relieve pain with timely inclusion of intervention. Careful evaluation of psychosocial and mental components with good communication is necessary. Barriers to cancer pain management should be overcome with an interdisciplinary approach aiming to provide adequate analgesia with minimal side-effects. Management of cancer pain should comprise not only a physical component but also psychosocial and mental components and social need of the patient. With risk-benefit analysis, interventional techniques should be included in an early stage of pain treatment. This article summarizes the need for early and effective pain management strategies, awareness regarding pain control, and barriers of cancer pain.

    Objective: To observe the effects of p38 mitogen activated protein kinase (MAPK) inhibitor SB203580 by intrathecal injection on the pain behavior and the spinal proinflammatory cytokines in a rat model of bone cancer pain induced by breast cancer cells. Methods: Eleven rats were used to establish the models of bone cancer pain, six rats were treated by intrathecal SB203580 injection, and the other 5 were as the controls. The paw withdrawal latency (PWL), histology and the spinal levels of IL-1β and TNF-α were detected. Results: All the 11 rats presented evident bone destruction and thermal hyperalgesia after intra-tibial injection of breast cancer cells. No effect of SB203580 on the bone destruction was observed.However, following intrathecal injection of SB203580, the left PWLs (12.12±1.26 s at 16 days and 12.99±1.65 s at 19 days)were significant higher than that of controls (9.05±1.08 s at 16 days and 8.55±1.60 s at 19 days), P<0.05. Meanwhile,intrathecal injection of SB203580 evidently reduced the levels of spinal IL-1βand TNF-α. Conclusion: Intrathecal injection of SB203580 in a rat model of bone cancer pain cannot prevent the tibial destruction but significantly depress the thermalgia sensitivity, which might result from inhibiting intracellular p38 MAPK signaling transduction, and thereby reducing the release of the proinflammatory cytokines.

    Bone health and maintenance of bone integrity are important components of comprehensive cancer care. Many patients with cancer are at risk for therapy-induced bone loss, with resultant osteoporotic fractures, or skeletal metastases, which may result in pathologic fractures, hypercalcemia, bone pain, and decline in motility and performance status. Effective screening and timely interventions are essential for reducing bone-related morbidity. Management of long-term bone health requires a broad knowledge base. A multidisciplinary health care team may be needed for optimal assessment and treatment of bone-related issues in patients with cancer. Since publication of the previous NCCN Task Force Report: Bone Health in Cancer Care in 2009, new data have emerged on bone health and treatment, prompting NCCN to convene this multidisciplinary task force to discuss the progress made in optimizing bone health in patients with cancer. In December 2012, the panel members provided didactic presentations on various topics, integrating expert judgment with a review of the key literature. This report summarizes issues surrounding bone health in cancer care presented and discussed during this NCCN Bone Health in Cancer Care Task Force meeting.

    associated with release of proinflammatory cytokines from glial cells,causing increased neuronal excitability and exaggerated nociception.Mounting evidence implies a critical role of P2X7R in inflammatory and neuropathic pain.However,whether P2X7R is involved in cancer pain remains controversial.Here we established a bone cancer pain model by injecting the Lewis lung carcinoma cells into the femur bone marrow cavity of C57BL/6J wild-type mice (C57 WT mice) and P2X7R knockout mice (P2rx7-/-mice) to explore the role of P2X7R in bone cancer pain.Following intrafemur carcinoma inoculation,robust mechanical allodynia and thermal hyperalgesia in C57 WT mice were developed on day 7 and 14,respectively,and persisted for at least 28 days in the ipsilateral hindpaw of the affected limb.CatWalk gait analysis showed significant decreases in the print area and stand phase,and a significant increase in swing phase in the ipsilateral hindpaw on day 21 and 28 after carcinoma cells inoculation.Histopathological sections (hematoxylin and eosin stain) showed that the bone marrow of the affected femur was largely replaced by invading tumor cells,and the femur displayed medullary bone loss and bone destruction on day 28 after inoculation.Unexpectedly,no significant changes in bone cancer-induced hypersensitivity of pain behaviors were found in P2rx7/-mice,and the changes of pain-related values in CatWalk gait analysis even occurred earlier in P2rx7-/-mice,as compared with C57 WT mice.Together with our previous study in rats that blockade of P2X7R significantly alleviated bone cancer pain,it is implied that P2X7R may play different roles in bone cancer pain in different species (e.g.rat vs mouse).These results implicated a huge difference between the pathophysiology discovered in the experimental animal models and that of human disease.

    Bone is the preferred site of metastasis for breast cancer, and presence of skeletal lesions is associated with significant morbidity and poor prognosis. Skeletal-related effects such as pain, pathologic fractures, spinal compression, and hypercalcemia are frequent consequences of skeletal lesions of breast cancer that have debilitating effects on the patients' quality of life. In addition to direct cancer effects on the skeleton, therapies commonly used to treat patients with breast cancer such as chemotherapy and aromatase inhibitors (AI) result in cancer therapy-induced bone loss (CTIBL) which is associated with increased risk of skeletal complications such as fractures. Bisphosphonates are a class of antiresorptive drugs that are now firmly established as the cornerstone of the management of skeletal-related events due to breast cancer. Other novel bone-targeting agents such as the anti-receptor activator of NF-κB ligand (RANKL) monoclonal antibody denosumab are also showing promising activity in the treatment of bone metastasis secondary to breast cancer. Moreover, recent provocative evidence suggests that bisphosphonates might also exhibit antitumor activity via direct and indirect mechanisms. The goal of this review is to summarize the pathophysiology of osteolytic bone lesions secondary to breast cancer, provide clinical evidence of currently available bone-targeted drugs in the treatment of bone metastasis and CTIBL, and explore the antitumor activity of current bone-targeted agents in patients with breast cancer.

    Some of the most common human cancers, including breast cancer, prostate cancer, and lung cancer, metastasize with avidity to bone. What is the basis for their preferential growth within the bone microenvironment? Bidirectional interactions between tumor cells and cells that make up bone result in a selective advantage for tumor growth and can lead to bone destruction or new bone matrix deposition. This review discusses our current understanding of the molecular components and mechanisms that are responsible for those interactions.

    Full Text Available Bone pain is a common and severe symptom in cancer patients. The present study employed a mouse model of leukemia bone pain by injection K562 cells into tibia of mouse to evaluate the analgesic effects of lappacontine. Our results showed that the lappaconitine treatment at day 15, 17 and 19 could effectively reduce the spontaneous pain scoring values, restore reduced degree in the inclined-plate test induced by injection of K562 cells, as well as restore paw mechanical withdrawal threshold and paw withdrawal thermal latency induced by injection of K562 cells to the normal levels. Additionally, the molecular mechanisms of lappaconitine’s analgesic effects may be related to affect the expression levels of endogenous opioid system genes (POMC, PENK and MOR, as well as apoptosis-related genes (Xiap, Smac, Bim, NF-κB and p53. Our present results indicated that lappaconitine may become a new analgesic agent for leukemia bone pain management.

    Full Text Available CONTEXT: More than 50% of patients with prostate, breast or lung cancer will develop painful bone metastases. The purpose of treating bone metastases is to relieve pain, reduce the use of steroids and to maintain motion. OBJECTIVE: To evaluate the use of samarium-153-EDTMP (153Sm-EDTMP for the treatment of bone pain secondary to metastases that is refractory to clinical management. TYPE OF STUDY: Retrospective. SETTING: Division of Nuclear Medicine, Universidade Estadual de Campinas (Unicamp. METHODS: Fifty-eight patients were studied (34 males with mean age 62 years; 31 patients had prostate cancer, 20 had breast cancer, three had lung cancer, one had lung hemangioendothelioma, one had parathyroid adenocarcinoma, one had osteosarcoma and one had an unknown primary tumor. All patients had multiple bone metastases demonstrated by bone scintigraphy using 99mTc-MDP,and were treated with 153Sm-EDTMP. Response to treatment was graded as good (pain reduction of 50-100%, intermediate (25-49% and poor (0-24%. RESULTS: All patients showed good uptake of 153Sm-EDTMP by bone metastases. Among the patients with prostate cancer, intermediate or good response to therapy occurred in 80.6% (25 patients and poor response in 19.4% (6. Among the patients with breast cancer, 85% (17 showed intermediate or good response to therapy while 15% (3 showed poor response. All three patients with lung cancer showed poor response to treatment. The lung hemangioendothelioma and unknown primary lesion patients showed intermediate response to treatment; the osteosarcoma and parathyroid adenocarcinoma patients showed good response to treatment. No significant myelotoxicity occurred. DISCUSSION: Pain control is important for improving the quality of life of patients with advanced cancers. The mechanism by which pain is relieved with the use of radionuclides is still not yet completely understood, however, the treatment is simple and provides a low risk of mielotoxicity

    Full Text Available In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression. Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach.

    Full Text Available MH Wong, N PavlakisDepartment of Medical Oncology, Royal North Shore Hospital, Sydney, NSW, AustraliaAbstract: Bone metastasis in breast cancer is a significant clinical problem. It not only indicates incurable disease with a guarded prognosis, but is also associated with skeletal-related morbidities including bone pain, pathological fractures, spinal cord compression, and hypercalcemia. In recent years, the mechanism of bone metastasis has been further elucidated. Bone metastasis involves a vicious cycle of close interaction between the tumor and the bone microenvironment. In patients with bone metastases, the goal of management is to prevent further skeletal-related events, manage complications, reduce bone pain, and improve quality of life. Bisphosphonates are a proven therapy for the above indications. Recently, a drug of a different class, the RANK ligand antibody, denosumab, has been shown to reduce skeletal-related events more than the bisphosphonate, zoledronic acid. Other strategies of clinical value may include surgery, radiotherapy, radiopharmaceuticals, and, of course, effective systemic therapy. In early breast cancer, bisphosphonates may have an antitumor effect and prevent both bone and non-bone metastases. Whilst two important Phase III trials with conflicting results have led to controversy in this topic, final results from these and other key Phase III trials must still be awaited before a firm conclusion can be drawn about the use of bisphosphonates in this setting. Advances in bone markers, predictive biomarkers, multi-imaging modalities, and the introduction of novel agents have ushered in a new era of proactive management for bone metastases in breast cancer.Keywords: breast cancer, bone metastases, bisphosphonates, denosumab, biomarkers, optimal management

  12. Dissecting Tumor-Stromal Interactions in Breast Cancer Bone Metastasis

    2016-06-01

    Full Text Available Bone metastasis is a frequent occurrence in breast cancer, affecting more than 70% of late stage cancer patients with severe complications such as fracture, bone pain, and hypercalcemia. The pathogenesis of osteolytic bone metastasis depends on cross-communications between tumor cells and various stromal cells residing in the bone microenvironment. Several growth factor signaling pathways, secreted micro RNAs (miRNAs and exosomes are functional mediators of tumor-stromal interactions in bone metastasis. We developed a functional genomic approach to systemically identified molecular pathways utilized by breast cancer cells to engage the bone stroma in order to generate osteolytic bone metastasis. We showed that elevated expression of vascular cell adhesion molecule 1 (VCAM1 in disseminated breast tumor cells mediates the recruitment of pre-osteoclasts and promotes their differentiation to mature osteoclasts during the bone metastasis formation. Transforming growth factor β (TGF-β is released from bone matrix upon bone destruction, and signals to breast cancer to further enhance their malignancy in developing bone metastasis. We furthered identified Jagged1 as a TGF-β target genes in tumor cells that engaged bone stromal cells through the activation of Notch signaling to provide a positive feedback to promote tumor growth and to activate osteoclast differentiation. Substantially change in miRNA expression was observed in osteoclasts during their differentiation and maturation, which can be exploited as circulating biomarkers of emerging bone metastasis and therapeutic targets for the treatment of bone metastasis. Further research in this direction may lead to improved diagnosis and treatment strategies for bone metastasis.

    Cancer pain is prevalent, undertreated, and feared by patients with cancer. In April 2013, a panel of pain experts convened in Singapore to address the treatment of cancer pain. They discussed the various types of cancer pain, including breakthrough pain, which is sometimes clinically confused with analgesic gaps. Reasons for undertreating cancer pain include attitudes of patients, clinicians, and factors associated with healthcare systems. The consequences of not treating cancer pain may include reduced quality of life for patients with cancer (who now live longer than ever), functional decline, and increased psychological stress. Early analgesic intervention for cancer pain may reduce the risk of central sensitization and chronification of pain. To manage pain in oncology patients, clinicians should assess pain during regular follow-up visits using validated pain measurement tools and follow prescribing guidelines, if necessary referring patients with cancer to pain specialists. Many patients with cancer require opioids for pain relief. Pain associated with cancer may also relate to cancer treatments, such as chemotherapy-induced peripheral neuropathy. Many patients with cancer are what might be considered "special populations," in that they may be elderly, frail, comorbid, or have end-stage organ failure. Specific pain therapy guidelines for those populations are reviewed. Patients with cancer with a history of or active substance abuse disorder deserve pain control but may require close medical supervision. While much "treatment inertia" exists in cancer pain control, cancer pain can be safely and effectively managed and should be carried out to alleviate suffering and improve outcomes.

    Bone metastases in prostate cancer constitute the most frequent cause of systemic failure in treatment, which results in numerous complications and finally leads to patient's death. Pain is one of the first and most important clinical symptoms of bone metastases and can be found among more than 80% of patients. Therefore, the most analgetic effective and simultaneously the least toxic treatment is an important point of therapeutic management in this group of patients. The aim of this prospective clinical trial was a comparison of analgetic effectiveness and toxicity of monotherapy with 153Sm isotope to combined therapy (153Sm + EBRT) among patients diagnosed with multiple painful bone metastases due to CRPC (mCRPC). 177 patients with mCRPC were included into the prospective randomised clinical trial in which 89 patients were assigned to the 153Sm isotope monotherapy, while 88 patients were assigned to the combined therapy including 153Sm isotope therapy and EBRT. All patients were diagnosed (bone scan and X-ray or/and CT or/and MRI) with painful bone metastases (bone pain intensity >= 6 according to VAS classification). The following additional inclusion criteria were established: histologically confirmed adenocarcinoma of prostate, multifocal bone metastases, no prior chemotherapy or palliative radiotherapy to bone. All patients signed informed consent.The combination of the isotope therapy with EBRT was more effective analgetic treatment than isotope therapy alone. The highest pain decline was noticed in the first weeks after treatment termination. In the whole group, a total or partial analgesic effect was observed among 154 (87%) patients while among 23 (13%) patients there was a lack of analgesic effect or even pain intensification. The results of this clinical trial demonstrated that for patients with multiple mCRPC it is recommended to combine the 153Sm isotope therapy with local EBRT because of a greater analgetic effect. It is important to note that

    Pain and quality of life following palliative radiotherapy of bone metastases Background and purpose: palliative irradiation is used to provide pain relief and to increase quality of life. Most studies exclude patients with advanced cancer disease and, therefore, a positive selection results. This prospective clinical study investigates the effect of palliative radiotherapy on pain and quality of life of patients with painful bone metastases. Patients and methods: 263 patients with bone metastases due to advanced cancer were observed with respect to pain and quality of life during a 2-month course of radiotherapy. Missing data were substituted by the LOCF method (last observation carried forward) to prevent a biased reduction of data. Results: radiotherapy resulted in pain relief. In the complete group, pain medication was not increased. Quality of life was not affected positively. Side effects of radiotherapy increased remarkably. Conclusion: Radiotherapy leads to pain relief. However, risks and benefits must be considered critically due to side effects. (orig.)

    Nurses spend more time with patients than any other member of the healthcare team. They play a critical, active and very important part in controlling cancer patients' pain and alleviating suffering. In controlling cancer pain the nurse needs to understand the psychological state of the cancer patient, cancer pain, cancer pain treatment, deleterious effects of unrelieved cancer pain and patient's socio cultural background. She needs to understand that there are two types of pain, nociceptive and neuropathic pains and that 80% of the cancer patients in pain could have 2 or more than 4 different pains at the same time. Nurses' role in controlling cancer pain include believing the patient, assessing pain, identifying the root of the problem, planning the care, administering medication, evaluating effectiveness, ensuring good pain control and individualizing treatment. It also includes nursing interventions such as giving tender nursing care, preventing pain, educating, advocating, communicating, comforting, supporting, and counseling the patient. The nurse must use both pharmacological and non pharmacological treatments to individualize treatment, know all the drugs that are used for the treatment of Cancer Pain, how these drugs relieve pain and what their side effects are. She must use the WHO guidelines to treat pain and must choose the right drug, right dose, given at the right times, with the right intervals and to the right patient. She must evaluate effectiveness of treatment, give PRN doses for breakthrough pain and recommend for specific changes. The role of the nurse is to anticipate the patient's pain needs, advocate for the patient for what feels appropriate for him within his cultural context and incorporate the patient's belief. The nurse can physically relieve pain by promoting comfort, support painful area, gentleness in handling the patient and use nursing treatments. The nurse can recommend physiotherapy, (TENS)/Acupuncture, Occupational therapy

    Full Text Available Aim of study: To investigate the features, adverse effects, bone marker changes in patients with breast cancer, prostate cancer, and multiple myeloma with bone metastases under Zometa® therapy. Materials and Methods: This post-marketing study included 414 Taiwanese patients with bone metastases secondary to breast cancer, prostate cancer, or multiple myeloma who received Zometa® for 48 weeks. The patients′ characteristics, medication and adverse events were recorded, meanwhile changes in four serum bone metabolic markers and pain reduction were assessed every three months for one year. Results: A total of 3,711 doses of Zometa® were infused, accounting for 294.5 patient-years. Adverse events occurred in 9.4% of patients, with bone pain, insomnia, constipation, and pyrexia as the most frequently reported. There was no osteonecrosis of the jaw. The incidence of skeletal-related events decreased significantly from 44.9% to 18.8%. Serum NTx, BAP, and TRACP5b steadily decreased to nadir at six months, but serum OPG was persistently elevated until the end of one year. The average decrease in pain score was 14.1, 14.3, and 16.7 for prostate cancer, breast cancer, and multiple myeloma patients, respectively. Conclusion: Zometa® can be safely administered in Taiwanese patients with bone metastases secondary to breast cancer, prostate cancer, and multiple myeloma. There are concomitant decreases in skeletal-related events and bone pain.

    Full Text Available Introduction: Involvement of the skeleton can cause an excruciating pain in two-thirds of terminal patients with a history of malignancy. Due to several limitations of other therapies, such as analgesics, bisphosphonates, chemotherapy, hormonal therapy and external beam radiotherapy; bone-seeking radiopharmaceuticals have an important role in palliation of pain from bone metastases. Although these kinds of therapies have many advantages including the ability to treat multiple sites of tumoral involvement simultaneously, no significant confliction with other treatments, ease of administration and the potential to be used repetitively; in Iran using of this modality is not widely practiced. In this study we evaluated the clinical usefulness of Sm-153 lexidronamfor pain management of bone metastases. Methods: 28 patients (14 males and 14 females aged 38-77 years with a history of painful bone metastases caused by different cancers, not responding to conventional treatments were included in the study. All patients had a recent whole body bone scan indicating multiple bone metastases. 1 mCi/Kg Sm-153 lexidronam was injected intravenously to the patients. Whole body scintigraphy was done 3 or 18 hours post injection. Pain relief and quality of life have been evaluated by analog pain scale and Karnofsky index every week, respectively. Also, all patients were evaluated for hematological toxicity every two weeks. Active follow ups were performed. Results: 43% of patients showed the presence of the flare phenomenon during the first three days after Sm injection with a mean duration of 2.2 days.

    Clonidine is an alpha2-adrenergic agonist with analgetic properties. Due to its side-effects, the drug is administered via the epidural or spinal route. A literature search yielded nine controlled studies on clonidine as a supplemental drug in the epidural or spinal treatment of cancer pain....... These studies were systematically reviewed to evaluate the evidence of efficacy in patients with cancer pain. CONCLUSION: Despite weak evidence, clonidine may be a useful adjunct in epidural or spinal morphine therapy of cancer pain Udgivelsesdato: 2008/11/3...

    Neuropathic pain (NP) in children with cancer is not well characterized. In a retrospective review of patient data from a 3.5-year period, we describe the prevalence of NP and the characteristics, duration of follow-up, and interventions provided for NP among patients referred to a pediatric oncology center's pain management service. Fifteen percent (66/439) of all referrals to our pain service were for NP (56/323 patients [17%]; 34 male, 22 female). The NP patient group had 1,401 clinical visits (778 inpatient visits [55.5%] and 623 outpatient visits [44.5%]). Patients with NP had a significantly greater mean number of pain visits per consultation (p = .008) and significantly more days of pain service follow-up (p cancer treatment rather than the underlying malignancy. Pharmacologic management of NP was complex, often comprising three medications. Nonpharmacologic approaches were used for 57.6% of NP referrals. Neuropathic pain is less frequently encountered than non-NP in children with cancer; nevertheless, it is more difficult to treat, requiring longer follow-up, more clinical visits, complex pharmacologic management, and the frequent addition of nonpharmacologic interventions.

    It remains unclear as to whether P2Y1 purinergic receptor (P2Y1R) and the molecules that act downstream,such as extracellular signal-regulated protein kinase 1/2 (ERK1/2),are involved in the development of cancer-induced bone pain (CIBP) in vivo.Here,we investigated the role of the P2Y1R in the modulation of CIBP-associated nociception in spinal cord and dorsal root ganglia (DRG).A CIBP model was established by inoculating Walker 256 gland carcinoma cells into the tibia of female rats.Tactile ailodynia and spontaneous pain were assessed using von Frey filaments and ambulatory scores.The results showed that both the paw withdrawal latency to tactile allodynia and the ambulatory score to spontaneous pain were significantly different between the CIBP group and the sham group on days 7-9 post-inoculation (P < 0.01).Furthermore,rats in the CIBP group also showed a progressive increase in ambulatory score,which is different from the sham group (P<0.01).Furthermore,P2Y1R mRNA and phosphory lated ERK1/2 (p-ERK1/2) protein expression levels were increased in the spinal dorsal horn and DRG of the CIBP group relative to the sham group.However,intrathecal injection of the P2Y1R antagonist MRS2179 decreased P2Y1R mRNA and p-ERK1/2 protein expression in the spinal dorsal horn and DRG (P<0.01).These results provide evidence that the inhibition of P2Y1R-mediated ERK1/2 phosphorylation in the spinal dorsal horn and DRG can attenuate nociception transmission.

    Giant cell bone tumors are the most common precursor lesions of aneurysmal bone cysts (ABCs) developing secondarily. In giant cell bone tumors containing an explicit ABC component, the observation of the solid component of the giant cell bone tumor plays a critical role in the separation of the primary ABC. In general, ABC cases together with giant cell tumors in the bone are diagnosed histopathologically. The combination of giant cell bone tumor with superposed ABC and that of painful scoliosis with backache is rarely seen in children. In this case study, we discussed the diagnosis and the treatment of a giant cell tumor and superposed an ABC present in the fifth lumbar spine in a pediatric patient admitted to our clinic with a complaint of acute scoliotic back pain.

    Full Text Available Abstract Background On-going pain is one of the most debilitating symptoms associated with a variety of chronic pain disorders. An understanding of mechanisms underlying on-going pain, i.e. stimulus-independent pain has been hampered so far by a lack of behavioural parameters which enable studying it in experimental animals. Ultrasound vocalizations (USVs have been proposed to correlate with pain evoked by an acute activation of nociceptors. However, literature on the utility of USVs as an indicator of chronic pain is very controversial. A majority of these inconsistencies arise from parameters confounding behavioural experiments, which include novelty, fear and stress due to restrain, amongst others. Results We have developed an improved assay which overcomes these confounding factors and enables studying USVs in freely moving mice repetitively over several weeks. Using this improved assay, we report here that USVs increase significantly in mice with bone metastases-induced cancer pain or neuropathic pain for several weeks, in comparison to sham-treated mice. Importantly, analgesic drugs which are known to alleviate tumour pain or neuropathic pain in human patients significantly reduce USVs as well as mechanical allodynia in corresponding mouse models. Conclusions We show that studying USVs and mechanical allodynia in the same cohort of mice enables comparing the temporal progression of on-going pain (i.e. stimulus-independent pain and stimulus-evoked pain in these clinically highly-relevant forms of chronic pain.

    Bone crises in type 1 Gaucher disease are reported in long bones and occasionally in weight bearing bones and other bones, but rarely in small bones of the hands and feet. We retrospectively examined the incidence of bone pain in patients followed at the Rabin Medical Center, Israel, before and following the initiation of enzyme replacement therapy (ERT) and evaluated them for bone crises. Of 100 type I Gaucher disease patients, 30 (30%) experienced one or more bone crises. Small bone crises represented 31.5% of all bone crises and were always preceded by crises in other bones. While the incidence of long bone crises reduced after the initiation of ERT, small bone crises increased. Almost 60% of patients with bone crises were of the N370S/84GG genotype suggesting a greater susceptibility of N370S/84GG patients to severe bone complications. These patients also underwent the greatest number of splenectomies (70.6% of splenectomised patients). Splenectomised patients showed a trend towards increased long and small bone crises after surgery. Active investigation of acute pain in the hands and feet in patients in our cohort has revealed a high incidence of small bone crises. Physicians should consider imaging studies to investigate unexplained pain in these areas.

Although variable, the prevalence of breakthrough cancer pain is high (33%–95%. According to the American Pain Foundation, breakthrough pain is observed in 50%–90% of all hospitalized cancer patients, in 89% of all patients admitted to homes for the elderly and terminal-patient care centers, and in 35% of all ambulatory care cancer patients. The management of breakthrough cancer pain should involve an interdisciplinary and multimodal approach. The introduction of new fentanyl formulations has represented a great advance and has notably improved treatment. Among these, the pectin-based intranasal formulation adjusts very well to the profile of breakthrough pain attacks, is effective, has a good toxicity profile, and allows for convenient dosing – affording rapid and effective analgesia with the added advantage of being easily administered by

    Aim To investigate the effect of intrathecal injection of CCR2 antagonist on pain behaviours,spinal astrocytes activation in the spinal cord in a rat model of bone cancer pain. Methods Forty female SD rats weighing 150 ~180 g were randomly divided into five groups ( n=8 each ):(Ⅰ) sham group;(Ⅱ) sham +RS102895 group;(Ⅲ) bone cancer pain group;(Ⅳ) bone cancer pain + DMSO group;(Ⅴ) bone cancer pain+RS102895 group. Rats received i. t. injections of either RS102895 (3 g·L-1 ) 10 μl or 10%DMSO 10 μl at the time of 10-12 days after the operation. Bone cancer was induced by intra-tibial inoculation of 1 × 105 Walker 256 breast cancer cell. Mechanical hind paw withdrawal threshold test was performed one day before and at 3rd,6th,9th, 10th,11th and 12th days after surgery. Immunofluorescence was used to observe the activation of the spinal astrocytes. Results Compared with group Ⅰ, the rats in bone cancer pain group appeared obvious mechanical hyperalgesia (Ⅲ、Ⅳ、Ⅴ) ,the volume,shape and mean optical den-sity ( MOD) of spinal astrocytes could be seen obvious-ly increased,groupⅡhad no obvious statistical signifi-cance (P>0. 05). Compared with group Ⅳ ,i. t. in-jections of RS102895 increased the paw mechanical withdrawal threshold, suppressed the action of astro-cytes,reduced the MOD of spinal astrocytes.

    Pharmacologic treatment of pain does not always meet patients' needs and may produce difficult side effects. Complementary therapies, which are safe, noninvasive, and generally considered to be relatively free of toxicity, may be used adjunctively with standard pain management techniques to improve outcome and reduce the need for prescription medication. Approaches such as acupuncture, massage therapy, mind-body interventions, and music therapy effectively reduce pain, enhance quality of life, and provide patients with the opportunity to participate in their own care. Such therapies have an important role in modern pain management.

    Full Text Available Bone metastases are a common complication of epithelial cancers, of which breast, prostate and lung carcinomas are the most common. The establishment of cancer cells to distant sites such as the bone microenvironment requires multiple steps. Tumour cells can acquire properties to allow epithelial-to-mesenchymal transition, extravasation and migration. Within the bone metastatic niche, disseminated tumour cells may enter a dormancy stage or proliferate to adapt and survive, interacting with bone cells such as hematopoietic stem cells, osteoblasts and osteoclasts. Cross-talk with the bone may alter tumour cell properties and, conversely, tumour cells may also acquire characteristics of the surrounding microenvironment, in a process known as osteomimicry. Alternatively, these cells may also express osteomimetic genes that allow cell survival or favour seeding to the bone marrow. The seeding of tumour cells in the bone disrupts bone-forming and bone-resorbing activities, which can lead to macrometastasis in bone. At present, bone macrometastases are incurable with only palliative treatment available. A better understanding of how these processes influence the early onset of bone metastasis may give insight into potential therapies. This review will focus on the early steps of bone colonisation, once disseminated tumour cells enter the bone marrow.

    To illustrate the effect of treatment with cementoplasty in patients with painful bone metastases in the extraspinal region. A retrospective study was conducted to review 51 consecutive patients who underwent cementoplasty under CT or fluoroscopic guidance, a total of 65 lesions involving the ilium, ischium, pubis, acetabulum, humeral, femur and tibia. In 5 patients with a high risk of impending fracture in long bones based on Mirels' scoring system, an innovative technique using a cement-filled catheter was applied. The clinical effects were evaluated using the visual analogue scale (VAS) preoperatively and postoperatively. All patients were treated successfully with a satisfying resolution of painful symptoms at 3 months' follow-up. Cement leakage was found in 8 lesions without any symptoms. VAS scores decreased from 8.19 ± 1.1 preoperatively to 4.94 ± 1.6 at 3 days, 3.41 ± 2.1 at 1 month and 3.02 ± 1.9 at 3 months postoperatively. There was a significant difference between the mean preoperative baseline score and the mean score at all of the postoperative follow-up points (P < 0.01). Cementoplasty is an effective technique for treating painful bone metastases in extraspinal regions, which is a valuable, minimally invasive, method that allows reduction of pain and improvement of patients' quality of life.

    Cancer pain, especially pain caused by metastasis to bone, is a severe type of pain, and unless the cause and consequences can be resolved, the pain will become chronic. As detection and survival among patients with cancer have improved, pain has become an increasing challenge, because traditional...... therapies are often only partially effective. Until recently, knowledge of cancer pain mechanisms was poor compared with understanding of neuropathic and inflammatory pain states. We now view cancer-induced bone pain as a complex pain state involving components of both inflammatory and neuropathic pain...... but also exhibiting elements that seem unique to cancer pain. In addition, the pain state is often unpredictable, and the intensity of the pain is highly variable, making it difficult to manage. The establishment of translational animal models has started to reveal some of the molecular components involved...

    Facial pain in lung cancer patients may be secondary to metastatic disease to the brain or skull base. Since 1983 there have been 19 published reports of hemi-facial pain as a non-metastatic complication of lung carcinoma. This report describes an additional case in whom unilateral face pain preceded the diagnosis of lung cancer by 9 months. A clinical diagnosis of trigeminal neuralgia was made after a normal brain CT scan. Later on the patient complained of global lethargy, weight loss and haemoptysis. A chest X-ray disclosed a 6 cm right hilar mass that was further defined with a whole body CT scan. The neural mechanism of the unilateral facial pain is discussed and the literature reviewed. 14 refs., 1 tab.

    A 77-year-old man, who received a renal transplant 13 years before for IgA glomerulonephritis, was referred after he developed bilateral mid-tibial aching pain that did not improve with simple analgesia. He had recently been changed from low-dose cyclosporine to tacrolimus, but the pain did not improve when this was reversed. He had a history of focal prostatic adenocarcinoma, cryptococcal lung infection, osteoporosis treated with alendronate for 2 years and multiple squamous cell carcinomas, including one requiring left neck dissection and radiotherapy. Upon physical examination, he had gouty tophi and marked bilateral tibial tenderness but had no other clinical findings. Laboratory investigations included an elevated intact parathyroid hormone value of 7.9 pmol/L (1.6 to 6.9), bone specific alkaline phosphatase of 22 µg/L (3.7 to 20.9), urinary deoxypyridinoline/creatinine ratio of 7.2 nmol/mmol (2.5 to 5.4) and C-reactive protein. Chest X-ray and tibial X-rays were normal, but there was marrow oedema and a prominent periosteal reaction on magnetic resonance imaging. A radionuclide bone scan showed increased symmetrical, linear uptake in both tibiae and the left femur, and uptake was also noted in both clinically asymptomatic humeri. Tibial bone biopsy disclosed small deposits of poorly differentiated metastatic cancer and a follow-up chest CT revealed a lung lesion. It was concluded that the bone pain and periostitis was caused by primary lung cancer with metastatic disease to bone, and an associated hypertrophic osteoarthropathy.

    Painful skeletal metastases are a common problem in cancer patients. Although external beam radiation therapy is the current standard of care for cancer patients who present with localized bone pain, 20-30% of patients treated with this modality do not experience pain relief, and few further options exist for these patients. For many patients with painful metastatic skeletal disease, analgesics remain the only alternative treatment option. Recently, image-guided percutaneous methods of tumor destruction have proven effective for treatment of this difficult problem. This review describes the application, limitations, and effectiveness of percutaneous ablative methods including ethanol, methyl methacrylate, laser-induced interstitial thermotherapy (LITT), cryoablation, and percutaneous radiofrequency ablation (RFA) for palliation of painful skeletal metastases.

  17. Bone sialoprotein and osteopontin in bone metastasis of osteotropic cancers.

    2014-02-01

    The mechanisms underlying malignant cell metastasis to secondary sites such as bone are complex and no doubt multifactorial. Members of the small integrin-binding ligand N-linked glycoproteins (SIBLINGs) family, particularly bone sialoprotein (BSP) and osteopontin (OPN), exhibit multiple activities known to promote malignant cell proliferation, detachment, invasion, and metastasis of several osteotropic cancers. The expression level of BSP and OPN is elevated in a variety of human cancers, particularly those that metastasize preferentially to the skeleton. Recent studies suggest that the "osteomimicry" of malignant cells is not only conferred by transmembrane receptors bound by BSP and OPN, but includes the "switch" in gene expression repertoire typically expressed in cells of skeletal lineage. Understanding the role of BSP and OPN in tumor progression, altered pathophysiology of bone microenvironment, and tumor metastasis to bone will likely result in development of better diagnostic approaches and therapeutic regimens for osteotropic malignant diseases.

    The purpose of this cross-sectional, correlational study was to describe stomatitis-related pain in women with breast cancer undergoing autologous hematopoietic stem cell transplant. The hypotheses that significant, positive relationships would exist between oral pain and stomatitis, state anxiety, depression, and alteration in swallowing were tested. Stomatitis, sensory dimension of oral pain, and state anxiety were hypothesized to most accurately predict oral pain overall intensity. Thirty-two women were recruited at 2 East Coast comprehensive cancer centers. Data were collected on bone marrow transplantation day +7 +/- 24 hours using Painometer, Oral Mucositis Index-20, Oral Assessment Guide, State-Trait Anxiety Inventory, and Beck Depression Inventory. Data analysis included descriptive statistics, correlations, and stepwise multiple regression. All participants had stomatitis; 47% had oral pain, with a subset reporting continuous moderate to severe oral pain despite pain management algorithms. Significant, positive associations were seen between oral pain, stomatitis, and alteration in swallowing and between oral pain with swallowing and alteration in swallowing. Oral pain was not significantly correlated with state anxiety and depression. Oral sensory and affective pain intensity most accurately predicted oral pain overall intensity. Future research needs to explore factors that affect perception and response to stomatitis-related oropharyngeal pain and individual patient response to opioid treatment.

  1. Improving cancer pain management in Malaysia.

    Science.gov (United States)

    Lim, Richard

    2008-01-01

    Within Malaysia's otherwise highly accessible public healthcare system, palliative medicine is still an underdeveloped discipline. Government surveys have shown that opioid consumption in Malaysia is dramatically lower than the global average, indicating a failure to meet the need for adequate pain control in terminally ill patients. Indeed, based on daily defined doses, only 24% of patients suffering from cancer pain receive regular opioid analgesia. The main barriers to effective pain control in Malaysia relate to physicians' and patients' attitudes towards the use of opioids. In one survey of physicians, 46% felt they lacked knowledge to manage patients with severe cancer pain, and 64% feared effects such as respiratory depression. Fear of addiction is common amongst patients, as is confusion regarding the legality of opioids. Additional barriers include the fact that no training in palliative care is given to medical students, and that smaller clinics often lack facilities to prepare and stock cheap oral morphine. A number of initiatives aim to improve the situation, including the establishment of palliative care departments in hospitals and implementation of post-graduate training programmes. Campaigns to raise public awareness are expected to increase patient demand for adequate cancer pain relief as part of good care.

    2017-03-01

    Purpose: To evaluate the clinical performance of MRgFUS in primary pain palliation of painful bone metastases and in local tumor control. Materials and Methods: We enrolled 26 consecutive patients (female/male 12/14; age: 64.7±7.5yrs) with painful bone metastases. Before and 3 months after MRgFUS treatment pain severity and pain interference scores were assessed according to Brief Pain Inventory-Quality of Life (BPI-QoL) criteria and patients underwent both CT and MRI. Local tumor control was evaluated according to lesion size, density and perfusion at CT, dynamic contrast enhancement at MRI (Discovery 750HD, GE; Gd-Bopta, Bracco) and metabolic activity at PET or scintigraphy. Patients were classified as responders or non-responders. Results: No treatment-related adverse events were recorded during the study. As statistically significant difference between baseline and follow-up values for both pain severity and pain interference scores was observed (p<0.05). Increased bone density was observed in 9/26 (34.6%) patients. Non-Perfused Volume values ranged between 20% and 92%. There was no difference in NPV values between responders and non-responders (46.7±24.2% [25 - 90 %] vs. 45±24.9% [20 - 93 %]; p=0.7). In 6 patients (5 prostate and 1 breast primary cancer) there was nearly absence of metabolic activity after treatment (mean SUV=1.2). Conclusion: MRgFUS can be safely and effectively used as the primary treatment for pain palliation in patients with painful bone metastases; moreover our experience demonstrated also a potential role for the MRgFUS in local tumor control.

    Full Text Available BACKGROUND: Systemic therapy with radionuclides may be used for the treatment of patients with painful skeletal metastases owing to its efficacy, low cost and low toxicity. Imported radionuclides for pain palliation, like Strontium-89 are expensive; particularly for developing countries. In the Indian scenario, Samarium-153 (Sm-153 is produced in our own reactors and as a result, it is readily available and economical. AIM: We undertook this study to determine the efficacy and toxicity of single-dose Sm-153 ethylenediamine tetramethylene phosphonate as a palliative treatment for painful skeletal metastases. MATERIALS AND METHODS: Eightysix patients with painful skeletal metastases from various primaries, were treated with Sm-153 EDTMP at a dose of 37 MBq/kg. The effects were evaluated according to change in visual analogue pain score, analgesic consumption, Karnofsky performance score, mobility score and blood count tests, conducted regularly for 16 weeks. STATISTICS: Repeated measures analysis. RESULTS: The overall response rates were 73%, while complete response was seen in 12.4%. Reduction in analgesic consumption with improvement in Karnofsky performance score and mobility score, was seen in all responders. Response rates were 80.3 and 80.5% in breast and prostate cancer, respectively. One case, each of Wilms tumor, ovarian cancer, germ cell tumor testis, multiple myeloma, primitive neuroectodermal tumor and oesophageal cancer, did not respond to therapy. No serious side-effects were noted, except for fall in white blood cell, platelet and haemoglobin counts, which gradually returned to normal levels by six-eight weeks. CONCLUSION: Sm-153 EDTMP provided effective palliation in 73% patients with painful bone metastases: the major toxicity was temporary myelosuppression.

  7. Do laying hens with keel bone fractures experience pain?

    The European ban on battery cages has forced a change towards the use of non-cage or furnished cage systems, but unexpectedly this has been associated with an increased prevalence of keel bone fractures in laying hens. Bone fractures are acutely painful in mammals, but the effect of fractures on bird welfare is unclear. We recently reported that keel bone fractures have an effect on bird mobility. One possible explanation for this is that flying becomes mechanically impaired. However it is also possible that if birds have a capacity to feel pain, then ongoing pain resulting from the fracture could contribute to decreased mobility. The aim was to provide proof of concept that administration of appropriate analgesic drugs improves mobility in birds with keel fracture; thereby contributing to the debate about the capacity of birds to experience pain and whether fractures are associated with pain in laying hens. In hens with keel fractures, butorphanol decreased the latency to land from perches compared with latencies recorded for these hens following saline (mean (SEM) landing time (seconds) birds with keel fractures treated with butorphanol and saline from the 50, 100 and 150 cm perch heights respectively 1.7 (0.3), 2.2 (0.3), p = 0.05, 50 cm; 12.5 (6.6), 16.9 (6.7), p = 0.03, 100 cm; 20.6 (7.4), 26.3 (7.6), p = 0.02 150 cm). Mobility indices were largely unchanged in birds without keel fractures following butorphanol. Critically, butorphanol can be considered analgesic in our study because it improved the ability of birds to perform a complex behaviour that requires both motivation and higher cognitive processing. This is the first study to provide a solid evidential base that birds with keel fractures experience pain, a finding that has significant implications for the welfare of laying hens that are housed in non-cage or furnished caged systems.

    Little is known about pain among long-term adult survivors of childhood cancers. The study investigated pain prevalence in this population compared with sibling controls and examined pain-related risk factors. Three self-reported pain outcomes including pain conditions, prescription analgesics used, and pain attributed to cancer and treatment were assessed among 10,397 cancer survivors and 3034 sibling controls from the Childhood Cancer Survivor Study. Pain conditions (pain/abnormal sensation, migraines, and other headaches) were reported by 12.3%, 15.5%, and 20.5% of survivors, respectively; 16.7% of survivors reported use of prescription analgesics, and 21% attributed pain to cancer and treatment. Risks of reporting pain conditions and using prescription analgesics were higher among survivors than siblings, adjusting for sociodemographic factors. Younger age at diagnosis and a history of non-Hodgkin lymphoma, Wilms tumor, or neuroblastoma (compared to leukemia) were associated with greater risk of reporting pain conditions. A history of bone cancer or soft tissue sarcoma (compared to leukemia) was associated with greater risks of using prescription analgesics and cancer-related pain attribution. Non-brain-directed scatter irradiation was associated with elevated risk for migraines and cancer-related pain attribution. Female gender and lower educational attainment were associated with increased reports of all 3 pain outcomes; minority status, unemployment, and being single were associated with greater risks for reporting pain conditions. These findings contribute to the understanding of pain and associated risk factors among adult survivors of childhood cancer and suggest areas of focus for pain intervention.

    One or more abnormal vertebrae detected on bone scintigraphy is a common finding in clinical practice, and it could pose a diagnostic dilemma especially in cancer patients, as either metastasis or benign disease may cause scintigraphic abnormality. The purpose of this study was to determine whether additional spine SPECT has a role in differentiating malignant from benign lesions in patients with back pain. We reviewed spine SPECT studies obtained over a three-year period in 108 patients. Among them, forty-five patients with abnormal SPECT and clinically followed records were evaluated (20 cancer patients were included). Uptake patterns were classified as follows: 1. Body: diffusely increased uptake, linear increased uptake of end plate, segmental increased uptake, and cold defect, 2 Posterior element; posterior to body (pedicle), posterior to intervertebral disc space (facet joint), and spinous process. Lesions were correlated with radiological findings and with final diagnosis. Sixty-nine bone lesions were detected on SPECT images, including 18 metastases, 28 degenerative diseases and 21 compression fractures. Cold defect (6) and segmental increased uptake (5) were dominant findings in metastasis: linear increased uptake (12), and facet joint uptake (15) were in degenerative change; and diffuse increased uptake (9), and linear increased uptake (9) were in compression fracture. Cold defect and segmental increased uptake of body were characteristic findings of metastasis, but care should be taken because compression fracture also shows segmental increased uptake in some cases. Degenerative disease was easily diagnosed because of the typical finding of linear increased uptake of end plate and facet joint. Therefore, additional bone SPECT after planar bone scan would be helpful for differentiating metastasis from benign condition in cancer patients.

    Treatment of chronic non-cancer pain with opioid therapy has escalated in recent years, resulting in exploding therapeutic use and misuse of prescription opioids and multiple adverse drug events. Breakthrough pain is defined as a transient exacerbation of pain experienced by individuals who have relatively stable and adequately controlled baseline cancer pain. Further, the definition of breakthrough pain, prevalence, characteristics, implications, and treatment modalities have been extensively described for chronic cancer pain. However, the literature for breakthrough pain in chronic non-cancer pain including its terminology, prevalence, relevance, characteristics, and treatments, have been poorly described and continue to be debated. The philosophy of breakthrough pain in chronic non-cancer pain raises multiple issues leading almost all patients to be on high dose long-acting opioids, followed by supplementing with short-acting drugs, instead of treating the patients with only short-acting drugs as required. Consequently, the subject of breakthrough pain in chronic non-cancer pain is looked at with suspicion due to the lack of evidence and inherent bias associated with its evaluation, followed by escalating use and abuse of opioids. Multiple issues related to the concept of breakthrough pain in chronic non-cancer pain evolve around extensive use, overuse, misuse, and abuse of opioids. In the era of eliminating opioids or significantly curtailing their use to only appropriate indications, the concept of breakthrough pain raises multiple questions without any scientific evidence. This review illustrates that there is no significant evidence for any type of breakthrough pain in chronic non-cancer pain based on available literature, methodology utilized, and response to opioids in chronic non-cancer pain. The advocacy for increased usage of opioids in the treatment of chronic pain dates back to the liberalization of laws governing opioid prescription for the treatment

    The purpose of this randomized controlled study was to investigate the effect of a pain education program (PEP) on pain intensity, patients' satisfaction with pain treatment, and patient-related barriers to pain management among Turkish patients with cancer. The study was conducted in a sample of 40 patients who were hospitalized for cancer and experiencing pain. The patients were equally randomized to either a PEP or a control group. The data were collected by means of the McGill Pain Questionnaire, the Numeric Rating Scale, and the Barrier Questionnaire-Revised. After the completion of the questionnaires at the first interview, patients in the PEP group received pain education using a pain educational booklet and an explanatory slide program that discussed the booklet's content with the patients. Patients in the control group received routine clinical care. The questionnaires were reapplied to the patients in both groups after 2, 4, and 8 weeks. Participation in a PEP was associated with decreased pain intensity scores for "present" and "least pain" during weeks 2, 4, and 8 (p satisfaction with pain treatment (p satisfaction with treatment, and decreases barriers about cancer pain management in cancer patients. Incorparation of PEP into the standard of care for cancer patients with pain may improve the quality of pain management.

    Six patients presented with musculoskeletal pain resulting from destructive bone lesions. These patients were ultimately shown to have metastatic pheochromocytoma. None of the cases exhibited typical symptoms of metastatic pheochromocytoma, nor was it suspected at the time of presentation. In three patients, hypertension caused pheochromocytoma to be considered as a diagnosis. The three remaining patients, all of whom had documented hypertension in the past, underwent bone biopsy. Two of these patients became markedly hypertensive in the postoperative period. Malignant pheochromocytoma may present with metastatic skeletal disease in some patients in whom the presence of hypertension as well as a carefully elicited history may suggest the diagnosis. In such patients, the possibility of pheochromocytoma should be taken into account, as biopsy may trigger a hypertensive crisis in patients not under adrenergic blockade.

    Full Text Available Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC stage T4N2M1b, with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabolically less active and remarkably smaller in size (reduction to 1/6 of the original volume. In spite of the good overall response, the patient developed a syndrome with severe bone pain and had progression in the bone marrow metastases, confirmed by 18F-FDG PET/CT. The patient received 153Sm-EDTMP treatment with a good clinical response. However, in the whole body bone scan with the therapeutic dose, there was no visual evidence of bone metastasis. Retrospectively, by drawing the region of interest, it was possible to identify one metastatic site. The possible mechanisms of the efficacy of this treatment modality, in this specific setting, are also discussed.

    Purpose. Assessment of effects of zoledronic acid therapy on bone metabolic indicators in hormone-resistant prostate cancer patients with bone metastasis. Material and Methods. Hormone-resistant prostate cancer patients who were identified to have metastases in their bone scintigraphy were taken to trial group. Before administration of zoledronic acid, routine tests for serum calcium, total alkalen phosphates were studied. Sample sera for bone metabolic indicators BALP, PINP, and ICTP were collected. Bone pain was assessed via visual analogue scale and performance via Karnofsky performance scale. Four mg zoledronic acid was administered intravenously once a month. Results. When serum levels of bone forming indicators PINP; BALP were compared before and after therapy, there were insignificant decreases (P = .33, P = .21, resp.). Serum levels of bone destruction indicator ICTP was compared, and there was a significant decrease after zoledronic acid therapy (P = .04). When performances of the patients were compared during therapy period, performances decreased significantly due to progress of illness (P = .01). All patients had ostalgia caused by bone metastases at various degrees. Significant decrease in pain scores was observed (P < .01). Conclusion. Zoledronic acid therapy decreased bone destruction and was effective in palliation of pain in patient with bone metastasis. Using bone metabolic indicators during followup of zoledronic acid therapy might be useful. PMID:22084798

    Purpose: Patients with bone metastases have a widely varying survival. A reliable estimation of survival is needed for appropriate treatment strategies. Our goal was to assess the value of simple prognostic factors, namely, patient and tumor characteristics, Karnofsky performance status (KPS), and patient-reported scores of pain and quality of life, to predict survival in patients with painful bone metastases. Methods and Materials: In the Dutch Bone Metastasis Study, 1157 patients were treated with radiation therapy for painful bone metastases. At randomization, physicians determined the KPS; patients rated general health on a visual analogue scale (VAS-gh), valuation of life on a verbal rating scale (VRS-vl) and pain intensity. To assess the predictive value of the variables, we used multivariate Cox proportional hazard analyses and C-statistics for discriminative value. Of the final model, calibration was assessed. External validation was performed on a dataset of 934 patients who were treated with radiation therapy for vertebral metastases. Results: Patients had mainly breast (39%), prostate (23%), or lung cancer (25%). After a maximum of 142 weeks' follow-up, 74% of patients had died. The best predictive model included sex, primary tumor, visceral metastases, KPS, VAS-gh, and VRS-vl (C-statistic = 0.72, 95% CI = 0.70-0.74). A reduced model, with only KPS and primary tumor, showed comparable discriminative capacity (C-statistic = 0.71, 95% CI = 0.69-0.72). External validation showed a C-statistic of 0.72 (95% CI = 0.70-0.73). Calibration of the derivation and the validation dataset showed underestimation of survival. Conclusion: In predicting survival in patients with painful bone metastases, KPS combined with primary tumor was comparable to a more complex model. Considering the amount of variables in complex models and the additional burden on patients, the simple model is preferred for daily use. In addition, a risk table for survival is

    Advances in combination chemotherapy, radiation therapy, surgery, and bone marrow transplantation have resulted in markedly improved survival rates for many children with cancer. Advancements in therapy, however, have led to new concerns, namely long-term consequences of effective treatments. Young adult and adult survivors of childhood cancer are at risk for a number of disorders related to therapy. Specifically, the young adult who has survived cancer, attendant treatments, and their complications is at risk for factors that can lead to suboptimal acquisition of peak bone mass. These factors include chronic illness, nutritional deficiencies, limited physical activity, and treatment with glucocorticoids, multiagent chemotherapy, and radiation. The long-term adverse effects of these therapies on endocrine systems, especially sex steroid and growth hormone deficiencies, are additional risk factors for some patients. After a brief review of the processes associated with acquisition of peak bone mass in the young adult, this article examines the impact of cancer and cancer therapy on bone mineral density in survivors of childhood cancer.

  20. Medical treatment of breast cancer bone metastasis: from bisphosphonates to targeted drugs.

    2014-01-01

    Breast cancer bone metastasis causing severe morbidity is commonly encountered in daily clinical practice. It causes pain, pathologic fractures, spinal cord and other nerve compression syndromes and life threatening hypercalcemia. Breast cancer metastasizes to bone through complicated steps in which numerous molecules play roles. Metastatic cells disrupt normal bone turnover and create a vicious cycle to which treatment efforts should be directed. Bisphosphonates have been used safely for more than two decades. As a group they delay time to first skeletal related event and reduce pain, but do not prevent development of bone metastasis in patients with no bone metastasis, and also do not prolong survival. The receptor activator for nuclear factor κB ligand inhibitor denosumab delays time to first skeletal related event and reduces the skeletal morbidity rate. Radionuclides are another treatment option for bone pain. New targeted therapies and radionuclides are still under investigation. In this review we will focus on mechanisms of bone metastasis and its medical treatment in breast cancer patients.

    Objective: The aim of this study was to assess the safety and the efficacy of radiofrequency thermal ablation (RFA) for pain relief and analgesics use reduction in two patients with painful bone metastases from hepatocellular carcinoma (HCC). Materials and methods: Two patients with lytic metastases from HCC located at the left superior ileo-pubic branch and at the middle arch of VII rib, performed RFA displacing a LeVeen Needle (3.5 and 4.0 cm diameter) under US (ultrasonography) and fluoroscopic guidance. Two methods were used to determine the response of both patients: the first method was to measure patient's worst pain with a Brief Pain Inventory (BPI) 1 day after the procedure, every week for 1 month, and thereafter at week 8 and 12 (total follow-up 3 months); Second method was to evaluate patient's analgesics use recorded at week 1, 4, 8 and 12. Analgesic medication use was translated into a morphine-equivalent dose. Results: The RFA were well tolerated by the patients who did not develop any complication. Both patients obtained substantial reduction of pain, which decreased from a mean score of 8 to approximately 2 in 4 weeks. In both patients we observed a reduction in the use of morphine dose-equivalent after a peak at week 1. CT (computed tomography) imaging, performed at 1 month after RFA, demonstrated that both procedures were technically successful and safe because consistent necrosis and no evidence for complications were observed. Conclusion: RFA provides a potential alternative method for palliation of painful osteolytic metastases from HCC; the procedure is safe, and the pain relief is substantial.

    Full Text Available Introduction One of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. Metastatic bone disease is the most common form of malignant bone tumors. Samarium-153-ethylene diamine tetramethylene phosphonate (153Sm-EDTMP as a radiopharmaceutical is used for pain palliation. This radiopharmaceutical usually emits beta particles, which have a high uptake in bone tissues. The purpose of this study was to calculate the radiation dose distribution of 153Sm-EDTMP in bone and other tissues, using MCNPX Monte Carlo code in the particle transport model. Materials and Methods Dose delivery to the bone was simulated by seeking radiopharmaceuticals on the bone surface. The phantom model had a simple cylindrical geometry and included bone, bone marrow, and soft tissue. Results The simulation results showed that a significant amount of radiation dose was delivered to the bone by the use of this radiopharmaceutical. Conclusion Thebone acted as a fine protective shield against rays for the bone marrow. Therefore, the trivial absorbed dose by the bone marrow caused less damage to bone-making cells. Also, the high absorbed dose of the bone could destroy cancer cells and relieve the pain in the bone.

    Bone metastasis from lung cancer requires a thorough examination of bones, including axial bones (e.g., spine, pelvis, and proximal femur) . Most patients have multiple bone metastases by the time they are initially diagnosed. In such patients, radiation therapy is often the first choice of treatment. Surgical treatment is indicated for pathological fracture and impending fracture associated with cortical bone invasion in long bone metastasis. Spinal metastasis requires accurate imaging to evaluate the extent of bone metastasis ; surgical treatment is indicated when the spinal cord is compressed. Given reports that bisphosphonates decrease the incidence of pathological fractures, prescribing bisphosphonates at an early stage is likely to be an effective therapeutic strategy for bone metastasis.

    Objective The aim of this study was to evaluate the ef icacy and time course of radiotherapy for pain relief in patients with bone metastases. Methods A total of 70 patients with painful bone metastases were investigated between January 2013 and August 2015. The patients were divided into 3 groups and each group was treated with radiotherapy using 30 Gy in 10 fractions, 20 Gy in 5 fractions, or a single dose of 8 Gy. The pain over the irradiated site was assessed using a numerical rating scale (NRS) ranging from 0 to 10. Pain relief was assessed every 5 days based on a pain questionnaire. Results Complete pain relief was achieved in 14.3% (10/70) patients; partial pain relief in 74.3% (52/70); and no response in 11.4% (8/70). The overal response rate was 88.6%. No significant dif erence was observed between single fraction radiotherapy and multifraction radiotherapy. There was no relationship between the pain relief and treated sites. The pain score gradual y decreased and most patients reached a moderate pain score (NRS Conclusion Local radiotherapy is a very rapid and ef ective pal iative treatment for painful bone metas-tases; however, the optimal dose and fractionation regimen remain debatable. Individualized therapy for painful bone metastases should be considered according to the patient’s condition and life expectancy.

    Full Text Available Purpose. Experimental data suggest that tumour cells can reversibly transition between epithelial and mesenchymal states (EMT and MET, a phenomenon known as cellular plasticity. The aim of this review was to appraise the clinical evidence for the role of cellular plasticity in prostate cancer (PC bone metastasis. Methods. An electronic search was performed using PubMed for studies that have examined the differential expression of epithelial, mesenchymal, and stem cell markers in human PC bone metastasis tissues. Results. The review included nineteen studies. More than 60% of the studies used ≤20 bone metastasis samples, and there were several sources of heterogeneity between studies. Overall, most stem cell markers analysed, except for CXCR4, were positively expressed in bone metastasis tissues, while the expression of EMT and MET markers was heterogeneous between and within samples. Several EMT and stemness markers that are involved in osteomimicry, such as Notch, Met receptor, and Wnt/β pathway, were highly expressed in bone metastases. Conclusions. Clinical findings support the role of cellular plasticity in PC bone metastasis and suggest that epithelial and mesenchymal states cannot be taken in isolation when targeting PC bone metastasis. The paper also highlights several challenges in the clinical detection of cellular plasticity.

Bone metastasis occurs in approximately 70% of breast cancer patients, and the goals of radiation therapy for bone metastasis are: palliation of pain, prevention and treatment of neuropathic symptoms, and prevention of pathologic fractures. The prognosis of bone metastasis from breast cancer is known to be better than that of bone metastasis from other solid tumors. Local-field radiation, hemibody (or wide-field) radiation, and systemic radionuclide treatment are the major methods of radiation therapy for pain palliation. Although many studies have shown that breast cancer is more responsive to radiation therapy for pain palliation than other solid tumors, some studies found no significant difference. Local-field radiation therapy, which includes multi-fraction irradiation and single-fraction irradiation, is currently the most generally used method of radiotherapy for pain palliation. Pain palliation has been reported to be achieved in approximately 80% to 90% of patients treated with local-field external beam irradiation. Three types of multi-fraction irradiation therapy are administered depending on the prognosis: high-dose fraction irradiation (36-50 Gy/12-25 Fr/2.4-5 wk), short-course irradiation (20-30 Gy/10-15 Fr/2-3 wk), and ultra-short-course irradiation (15-25 Gy/2-5 Fr/1 wk). The most common irradiation schedule is 30 Gy/10 Fr/2 wk. Although many reports indicate no significant difference in pain palliation according to the dose, the percentage of patients who show a complete cure is significantly higher in those treated with doses of 30 Gy or more, and thus the total irradiation dose should be at least 30 Gy. High-dose fraction irradiation is indicated for patients with an expected survival time of 6 months or more while short-course or single-fraction irradiation is indicated for those with an expected survival time of 3 months or more.

    Pain is unfortunately a quite common symptom for cancer patients. Normally pain starts as an episodic experience at early cancer phases to become chronic in later stages. In order to improve the quality of life of oncological patients, anti-cancer treatments are often accompanied by analgesic therapies. The P2 X receptor are adenosine triphosphate(ATP) gated ion channels expressed by several cells including neurons, cancer and immune cells. Purinergic signaling through P2 X receptors recently emerged as possible common pathway for cancer onset/growth and pain sensitivity. Indeed, tumor microenvironment is rich in extracellular ATP, which has a role in both tumor development and pain sensation. The study of the different mechanisms by which P2 X receptors favor cancer progression and relative pain, represents an interesting challenge to design integrated therapeutic strategies for oncological patients. This review summarizes recent findings linking P2 X receptors and ATP to cancer growth, progression and related pain. Special attention has been paid to the role of P2X2, P2X3, P2X4 and P2X7 in the genesisof cancer pain and to the function of P2X7 in tumor growth and metastasis. Therapeutic implications of the administration of different P2 X receptor blockers to alleviate cancer-associated pain sensations contemporarily reducing tumor progression are also discussed.

    Twenty years ago, the main barriers to successful cancer pain management were poor assessment by physicians, and patients' reluctance to report pain and take opioids. Those barriers are almost exactly the same today. Cancer pain remains under-treated; in Europe, almost three-quarters of cancer patients experience pain, and almost a quarter of those with moderate to severe pain do not receive any analgesic medication. Yet it has been suggested that pain management could be improved simply by ensuring that every consultation includes the patient's rating of pain, that the physician pays attention to this rating, and a plan is agreed to increase analgesia when it is inadequate. After outlining current concepts of carcinogenesis in some detail, this paper describes different methods of classifying and diagnosing cancer pain and the extent of current under-treatment. Key points are made regarding cancer pain management. Firstly, the pain may be caused by multiple different mechanisms and therapy should reflect those underlying mechanisms - rather than being simply based on pain intensity as recommended by the WHO three-step ladder. Secondly, a multidisciplinary approach is required which combines both pharmacological and non-pharmacological treatment, such as psychotherapy, exercise therapy and electrostimulation. The choice of analgesic agent and its route of administration are considered, along with various interventional procedures and the requirements of palliative care. Special attention is paid to the treatment of breakthrough pain (particularly with fast-acting fentanyl formulations, which have pharmacokinetic profiles that closely match those of breakthrough pain episodes) and chemotherapy-induced neuropathic pain, which affects around one third of patients who receive chemotherapy. Finally, the point is made that medical education should place a greater emphasis on pain therapy, both at undergraduate and postgraduate level.

    Full Text Available Intractable cancer pain not amenable to standard oral or parenteral analgesics is a horrifying truth in 10-15% of patients. Interventional pain management techniques are an indispensable arsenal in pain physician′s armamentarium for severe, intractable pain and can be broadly classified into neuroablative and neuromodulation techniques. An array of neurolytic techniques (chemical, thermal, or surgical can be employed for ablation of individual nerve fibers, plexuses, or intrathecalneurolysis in patients with resistant pain and short life-expectancy. Neuraxial administration of drugs and spinal cord stimulation to modulate or alter the pain perception constitutes the most frequently employed neuromodulation techniques. Lately, there is a rising call for early introduction of interventional techniques in carefully selected patients simultaneously or even before starting strong opioids. After decades of empirical use, it is the need of the hour to head towards professionalism and standardization in order to secure credibility of specialization and those practicing it. Even though the interventional management has found a definite place in cancer pain, there is a dearth of evidence-based practice guidelines for interventional therapies in cancer pain. This may be because of paucity of good quality randomized controlled trials (RCTs evaluating their safety and efficacy in cancer pain. Laying standardized guidelines based on existing and emerging evidence will act as a foundation step towards strengthening, credentialing, and dissemination of the specialty of interventional cancer pain management. This will also ensure an improved decision-making and quality of life (QoL of the suffering patients.

    The prevalence of cancer pain in patients with cancer is high. The majority of efforts are spent on research in cancer treatment, but only a small fraction focuses on cancer pain. Pain in cancer patients, viewed predominantly as a secondary issue, is considered to be due to the destruction of tissues, compression of the nerves, inflammation, and secretion of biological mediators from the necrotic tumor mass. As a result, opioid drugs have remained as the primary pharmacological therapy for cancer pain for the past hundred years. This report reviews evidence that cancer pain may be produced by the metabolic effects of two byproducts of cancer-high acidity in the cancer microenvironment and the secretion of formaldehyde and its metabolites. We propose the research and development of therapeutic approaches for preemptive, short- and long-term management of cancer pain using available drugs or nutraceutical agents that can suppress or neutralize lactic acid production in combination with formaldehyde scavengers. We believe this approach may not only improve cancer pain control but may also enhance the quality of life for patients.

    Beside its poor prognosis and its late diagnosis, pancreatic cancer remains one of the most painful malignancies. Optimal management of pain in this cancer represents a real challenge for the oncologist whose objective is to ensure a better quality of life to his patients. We aimed in this paper to review all the treatment modalities incriminated in the management of pain in pancreatic cancer going from painkillers, chemotherapy, radiation therapy and interventional techniques to agents under investigation and alternative medicine. Although specific guidelines and recommendations for pain management in pancreatic cancer are still absent, we present all the possible pain treatments, with a progression from medical multimodal treatment to radiotherapy and chemotherapy then interventional techniques in case of resistance. In addition, alternative methods such as acupuncture and hypnosis can be added at any stage and seems to contribute to pain relief.

    While spinal cord astrocytes play a key role in the generation of cancer pain, there have been no studies that have examined the relationship of tumor-induced astrocyte activation and aromatase expression during the development of cancer pain. Here, we examined tumor-induced mechanical hyperalgesia and cold allodynia, and changes in Glial fibrillary acid protein (GFAP) and aromatase expression in murine models of painful and non-painful bone cancer. We demonstrate that implantation of fibrosarcoma cells, but not melanoma cells, produces robust mechanical hyperalgesia and cold allodynia in tumor-bearing mice compared to saline-injected controls. Secondly, this increase in mechanical hyperalgesia and cold allodynia is mirrored by significant increases in both spinal astrocyte activity and aromatase expression in the dorsal horn of fibrosarcoma-bearing mice. Importantly, we show that aromatase is only found within a subset of astrocytes and not in neurons in the lumbar spinal cord. Finally, administration of an aromatase inhibitor reduced tumor-induced hyperalgesia in fibrosarcoma-bearing animals. We conclude that a painful fibrosarcoma tumor induces a significant increase in spinal astrocyte activation and aromatase expression and that the up-regulation of aromatase plays a role in the development of bone tumor-induced hyperalgesia. Since spinal aromatase is also upregulated, but to a lesser extent, in non-painful melanoma bone tumors, it may also be neuroprotective and responsive to the changing tumor environment.

    Purpose: evaluate the performance of the SPECT-CT after a normal or litigious planar bone scintigraphy in the pulmonary cancers with suspicious pains. conclusions: The SPECT-CT has good performances in the exploration of suspicious pains of pulmonary cancers. The comparison of results got at one year interval shows that these performances are clearly improved par experience. It seems logical to use the planar bone scintigraphy coupled to SPECT-CT in this indication. This bone imaging can have an interest in the surveillance of patients after curative or palliative treatment, when pains appear. (N.C.)

  4. Bone mineral density deficits in childhood cancer survivors: Pathophysiology, prevalence, screening, and management

    2013-02-01

    Full Text Available As chemotherapy and other sophisticated treatment strategies evolve and the number of survivors of long-term childhood cancer grows, the long-term complications of treatment and the cancer itself are becoming ever more important. One of the most important but often neglected complications is osteoporosis and increased risk of fracture during and after cancer treatment. Acquisition of optimal peak bone mass and strength during childhood and adolescence is critical to preventing osteoporosis later in life. However, most childhood cancer patients have multiple risk factors for bone mineral loss. Cancer itself, malnutrition, decreased physical activity during treatment, chemotherapeutic agents such as steroids, and radiotherapy cause bone mineral deficit. Furthermore, complications such as growth hormone deficiency and musculoskeletal deformity have negative effects on bone metabolism. Low bone mineral density is associated with fractures, skeletal deformity, pain, and substantial financial burden not only for childhood cancer survivors but also for public health care systems. Thus, it is important to monitor bone health in these patients and minimize their risk of developing osteoporosis and fragility fractures later in life.

  5. TGF-β in cancer and bone: implications for treatment of bone metastases.

    Bone metastases are common in patients with advanced breast, prostate and lung cancer. Tumor cells co-opt bone cells to drive a feed-forward cycle which disrupts normal bone remodeling to result in abnormal bone destruction or formation and tumor growth in bone. Transforming growth factor-beta (TGF-β) is a major bone-derived factor, which contributes to this vicious cycle of bone metastasis. TGF-β released from bone matrix during osteoclastic resorption stimulates tumor cells to produce osteolytic factors further increasing bone resorption adjacent to the tumor cells. TGF-β also regulates 1) key components of the metastatic cascade such as epithelial-mesenchymal transition, tumor cell invasion, angiogenesis and immunosuppression as well as 2) normal bone remodeling and coupling of bone resorption and formation. Preclinical models demonstrate that blockade of TGF-β signaling is effective to treat and prevent bone metastases as well as to increase bone mass.

    Research on biomaterials has been growing in the last few years due to the clinical needs in organs and tissues replacement and regeneration. In addition, cancer nanomedicine has recently appeared as an effective means to combine nanotechnology developments towards a clinical application. Ceramic materials are suitable candidates to be used in the manufacturing of bone-like scaffolds. Bioceramic materials may also be designed to deliver biologically active substances aimed at repairing, maintaining, restoring or improving the function of organs and tissues in the organism. Several materials such as calcium phosphates, glasses and glass ceramics able to load and subsequently release in a controlled fashion drugs, hormones, growth factors, peptides or nucleic acids have been developed. In particular, to prevent post surgical infections bioceramics may be surface modified and loaded with certain antibiotics, thus preventing the formation of bacterial biofilms. Remarkably, mesoporous bioactive glasses have shown excellent characteristics as drug carrying bone regeneration materials. These bioceramics are not only osteoconductive and osteoproductive, but also osteoinductive, and have therefore been proposed as ideal components for the fabrication of scaffolds for bone tissue engineering. A recent promising development of bioceramic materials is related to the design of magnetic mediators against tumors. Magnetic composites are suitable thermoseeds for cancer treatment by hyperthermia. Moreover, magnetic nanomaterials offer a wide range of possibilities for diagnosis and therapy. These nanoparticles may be conjugated with therapeutic agents and heat the surrounding tissue under the action of alternating magnetic fields, enabling hyperthermia of cancer as an effective adjunct to chemotherapy regimens.

    Full Text Available Pain in thalassemia proves to be an emergent issue even if it is not possible to correlate it definitely to bone disease, but we strongly believe that a multidisciplinary approach, may be as decisive in this case as it was in the struggle against thalassemia. In fact, we strongly believe that the involvement of various specialists such as endocrinologists, orthopedist, anesthesiologist, in a close team coordinated by a specialist in thalassemia is absolutely necessary for achieving our aims. First of all, we need to implement clinical trials to identify the mechanisms of disease, to find the optimal management of the problem in order to provide new therapeutic methods for preventing the thalassemia-induced osteoporosis and to reduce the presence of very disabling pain for patients. Patients’ expectations for the future are to continuously improve the quality of life. To do that it is needed to identify pathways to prevent all the complications of thalassemia that cause widespread pain, above all osteoporosis. Although we have seen that osteoporosis is not the sole cause of pain for thalassemia patients, it is true that this seems to have a great incidence in thalassemia patients and it gives a significant contribute to an increased pain. 地中海贫血疼痛亟待解决,即使它可能与和骨病毫不相关,但我们坚信可以找到一种战胜地中海贫血症的多学科结合疗法。 事实上,如果要完成我们的目标,绝对有必要邀请一名地中海贫血专家,在内分泌学家、矫形外科医师和麻醉学家组成的队伍的配合下紧密展开工作。 首先,我们需要开展临床试验,确认发病机制,找出疾病最佳的控制方法,以找到预防地中海贫血诱发骨质疏松症的新疗法和减少疼痛的频率。 病患者对未来的期望是能够不断地提高自己的生活质量。要做到,病患者需要找到预防地中海贫血所有并发症引起的疼痛的方

    2015-01-01

    Full Text Available Background: Bone metastasis is a usual cause of pain in advanced cancer. Conventional radiation schedules require larger hospital stay and thus are not suitable for patients with poor general condition. This prospective observational study aims to compare the pain-relieving efficacy of different radiation fractionation schedules, i.e., 8 Gy administered in a single fraction versus 30 Gy administered in 10 fractions. Materials and Methods: Two hundred and fifty consecutive patients of bone metastasis were evaluated for the study, with 63 patients being excluded due to non-fulfillment of the inclusion criteria. The response to radiotherapy leading to pain relief as per the Visual Analog Scale was recorded at the end of treatment, 8 days, 15 days and 1 month during the follow-up visits. Results: Sixty-two percent of the patients received a single fraction while the remaining received 10 fractions. In the 10-fraction group, overall response was present in 60% of the patients. Stable pain was present in 23% of the patients while 9% patients had progressive pain. At 1 month of completion of treatment, 9% patients were lost to follow-up. In the single-fraction arm, overall response was seen in 58%, stable pain in 27% and progressive pain in 7% of the patients. Six percent of the patients were lost to follow-up. Conclusions: Single-fraction treatment for bony metastasis is as effective as multiple fractions to relieve bony pain and provides treatment convenience to both the patient and the caregiver.

    OBJECTIVE To determine predictors of pain 1 year after the diagnosis of head and neck cancer. DESIGN Prospective, multisite cohort study. SETTING Three academically affiliated medical centers. PATIENTS The study population comprised 374 previously untreated patients with carcinoma of the upper aerodigestive tract. MAIN OUTCOME MEASURES Participants were surveyed before treatment and 1 year thereafter. Multivariate analyses were conducted to determine predictors of the 36-Item Short-Form Instrument (SF-36) bodily pain score 1 year after diagnosis. RESULTS The mean SF-36 bodily pain score at 1 year was 65, compared with 61 at the time of diagnosis (P = .004), and 75, the population norm (lower scores indicate worse pain). Variables independently associated with pain included pretreatment pain score (P neck dissection (P = .001), feeding tube (P = .05), xerostomia (P pain medication (P neck cancer pain and current smoking and problem drinking did not reach significance (P = .07 and P = .08, respectively). CONCLUSIONS Aggressive pain management may be indicated for patients with head and neck cancer who undergo neck dissections, complain of xerostomia, require feeding tubes, and have medical comorbidities. Treatment of modifiable risk factors such as depression, poor sleep quality, tobacco use, and alcohol abuse may also reduce pain and improve quality of life among patients with head and neck cancer.

    Full Text Available Pain due to cancer is one of the most distressing symptoms experienced by the patients at some or the other time during the course of treatment or disease progression. The multidimensional nature of cancer pain is characterized by various dimensions including physical, social, psychological, and spiritual; which together constitute the term "total pain". Young cancer patients illustrate their unique psychological and developmental needs. This case report highlights the concept of "total cancer pain" in a young adult and demonstrates his distinctive social, spiritual, and psychological sufferings. The report emphasizes that addressing all these concerns is considerably significant in order to provide optimal pain relief to the patient. In the present scenario, it has been done by a skillful multiprofessional team communicating effectively with both the patient and the carer.

    This review examines evidence for psychological factors that affect pain across the cancer continuum from diagnosis through treatment and long-term survivorship or end of life. Evidence is convincing that emotional distress, depression, anxiety, uncertainty, and hopelessness interact with pain. Unrelieved pain can increase a desire for hastened death. Patients with cancer use many strategies to manage pain, with catastrophizing associated with increased pain and self-efficacy associated with lower pain reports. A variety of psychological and cognitive behavioral treatments can reduce pain severity and interference with function, as indicated in multiple meta-analyses and high-quality randomized controlled trials. Effective methods include education (with coping skills training), hypnosis, cognitive behavioral approaches, and relaxation with imagery. Exercise has been tested extensively in patients with cancer and long-term survivors, but few exercise studies have evaluated pain outcomes. In survivors post-treatment, yoga and hypnosis as well as exercise show promise for controlling pain. Although some of these treatments effectively reduce pain for patients with advanced disease, few have been tested in patients at the end of life. Given the clear indicators that psychological factors affect cancer pain and that psychological and behavioral treatments are effective in reducing varying types of pain for patients with active disease, these methods need further testing in cancer survivors post-treatment and in patients with end-stage disease. Multidisciplinary teams are essential in oncology settings to integrate analgesic care and expertise in psychological and behavioral interventions in standard care for symptom management, including pain.

    Purpose: Reirradiation of painful bone metastases in nonresponders or patients with recurrent pain after initial response is performed in up to 42% of patients initially treated with radiotherapy. Literature on the effect of reirradiation for pain control in those patients is scarce. In this systematic review and meta-analysis, we quantify the effectiveness of reirradiation for achieving pain control in patients with painful bone metastases. Methods and Materials: A free text search was performed to identify eligible studies using the MEDLINE, EMBASE, and the Cochrane Collaboration library electronic databases. After study selection and quality assessment, a pooled estimate was calculated for overall pain response for reirradiation of metastatic bone pain. Results: Our literature search identified 707 titles, of which 10 articles were selected for systematic review and seven entered the meta-analysis. Overall study quality was mediocre. Of the 2,694 patients initially treated for metastatic bone pain, 527 (20%) patients underwent reirradiation. Overall, a pain response after reirradiation was achieved in 58% of patients (pooled overall response rate 0.58, 95% confidence interval = 0.49-0.67). There was a substantial between-study heterogeneity (I{sup 2} = 63.3%, p = 0.01) because of clinical and methodological differences between studies. Conclusions: Reirradiation of painful bone metastases is effective in terms of pain relief for a small majority of patients; approximately 40% of patients do not benefit from reirradiation. Although the validity of results is limited, this meta-analysis provides a comprehensive overview and the most quantitative estimate of reirradiation effectiveness to date.

    Cancer pain is the most common complaint among patients with cancer. Conventional treatment does not always relieve cancer pain satisfactorily. Therefore, many patients with cancer have turned to complementary therapies to help them with their physical, emotional, and spiritual well-being. Massage therapy is increasingly used for symptom relief in patients with cancer. The current study aimed to investigate by meta-analysis the effects of massage therapy for cancer patients experiencing pain. Nine electronic databases were systematically searched for studies published through August 2013 in English, Chinese, and Korean. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) and Cochrane risk-of-bias scales. Twelve studies, including 559 participants, were used in the meta-analysis. In 9 high-quality studies based on the PEDro scale (standardized mean difference, -1.24; 95% confidence interval, -1.72 to -0.75), we observed reduction in cancer pain after massage. Massage therapy significantly reduced cancer pain compared with no massage treatment or conventional care (standardized mean difference, -1.25; 95% confidence interval, -1.63 to -0.87). Our results indicate that massage is effective for the relief of cancer pain, especially for surgery-related pain. Among the various types of massage, foot reflexology appeared to be more effective than body or aroma massage. Our meta-analysis indicated a beneficial effect of massage for relief of cancer pain. Further well-designed, large studies with longer follow-up periods are needed to be able to draw firmer conclusions regarding the effectiveness.

    Full Text Available Abstract Introduction The medical management of secondary hyperparathyroidism in patients with end-stage renal disease involves a combination of dietary restrictions, phosphate binders, active vitamin D analogs, and calcimimetics. Case presentation We report the case of a 36-year-old Hispanic dialysis patient, originally from Cuba and now residing in the USA, who developed severe bone pain and muscle twitching after starting low dose cinacalcet, despite normal pre-dialysis ionized calcium and elevated parathyroid hormone. The clinical symptoms correlated with increased symmetrical uptake on bone scan that resolved rapidly upon discontinuation of cinacalcet. Conclusion Cinacalcet may induce severe bone pain and a unique bone scan uptake pattern in hemodialysis patients.

    To improve cancer pain management, the Medical Oncology Department of Sun Yat-sen University Cancer Center (SYSUCC) launched the Good Pain Management (GPM) Ward Program, which has been recognized by the Chinese Ministry of Health and promoted throughout the nation. This retrospective case-control study was designed to evaluate the effectiveness of the program. Patients diagnosed with malignant solid tumors with bone metastasis were eligible. Patients who were admitted 6 months before the initiation of the GPM program were used as the control group, and patients admitted 6 months after the initiation of the program were used as the GPM group. The pain-reporting rate and pain management index (PMI) were calculated. The pain levels before and after pain management were compared. A total of 475 patients (244 in the control group and 231 in the GPM group) were analyzed. The pain-reporting rate of the GPM group was significantly higher than that of the control group (62.8% vs. 37.7%,P< 0.001). The PMI of the GPM group was significantly higher than that of the control group (0.083 vs. -0.261,P< 0.001). Therefore, the GPM Ward Program improved the pain management of cancer patients and provided experience for improving cancer pain management in the future.

    Purpose: Radiation therapy (RT) is an effective method of palliating painful bone metastases and can improve function and reduce analgesic requirements. In advanced cancer patients, quality of life (QOL) is the primary outcome of interest over traditional endpoints such as survival. The purpose of our study was to compare bone metastasis-specific QOL scores among patients who responded differently to palliative RT. Methods and Materials: Patients receiving RT for bone metastases across 6 countries were prospectively enrolled from March 2010-January 2011 in a trial validating the QLQ-BM22 and completed the QLQ-BM22 and the core measure (QLQ-C30) at baseline and after 1 month. Pain scores and analgesic intake were recorded, and response to RT was determined according to the latest published guidelines. The Kruskal-Wallis nonparametric and Wilcoxon rank sum tests compared changes in QOL among response groups. A Bonferroni-adjusted P<.003 indicated statistical significance. Results: Of 79 patients who received palliative RT, 59 were assessable. Partial response, pain progression, and indeterminate response were observed in 22, 8, and 29 patients, respectively; there were no patients with a complete response. Patients across all groups had similar baseline QOL scores apart from physical functioning (patients who progressed had better initial functioning). One month after RT, patients who responded had significant improvements in 3 of 4 QLQ-BM22 domains (painful site, P<.0001; painful characteristic, P<.0001; and functional interference, P<.0001) and 3 QLQ-C30 domains (physical functioning, P=.0006; role functioning, P=.0026; and pain, P<.0001). Patients with progression in pain had significantly worse functional interference (P=.0007) and pain (P=.0019). Conclusions: Patients who report pain relief after palliative RT also have better QOL with respect to bone metastasis-specific issues. The QLQ-BM22 and QLQ-C30 are able to discriminate among patients with varying

    Full Text Available Introduction: Under treatment of pain is a recognized global issue. Opioid analgesic medication is the mainstay of treatment in cancer patients as per the World Health Organization (WHO pain relief ladder, yet 50% of cancer patients worldwide do not receive adequate pain relief or are undertreated. Aim: The aim of this study was to audit the ongoing opioid-prescribing practices in our tertiary cancer pain clinic during January-June 2010. Materials& Methods: The prescribed type of opioid, dose, dosing interval, and laxatives details were analyzed. Results: Five hundred pain files were reviewed and 435 were found complete for audit. Three hundred forty-eight (80% patients were prescribed opioids. Two hundred fifty-nine (74.4% received weak opioids while 118 (33.9% received strong opioids. A total of 195 (45% patients had moderate and 184 (42% had severe pain. Ninety-three (26.7% patients received morphine; however, only 31.5% (58 of 184 in severe pain received morphine as per the WHO pain ladder. Only 73 of 93 (78.4% patients received an adequate dose of morphine with an adequate dosing interval and only 27 (29% were prescribed laxatives with morphine. Conclusion: This study shows that the under treatment of pain and under dosing of opioids coupled with improper side effect management are major issues.

    Background: Systemic mast cell disease (SMCD) is a rare disease characterized by a multitopic proliferation of cytologically and/or functionally abnormal tissue mast cells. SMCD preferentially involves the skin, spleen, liver, lymph nodes and the bone marrow. The cause of SMCD is unknown. Bony pain, caused by mast cell infiltration of the marrow cavity, is present in up to 28% of cases and is frequently chronic and difficult to palliate with medical therapy. Case Report: We report one case of refractory bone pain in a 54-year-old female Caucasian patient with advanced SMCD and associated bony involvement, which was treated with radiotherapy for pain palliation. Between 1995 and 1998, the patient was irradiated at four different locations: 1) right shoulder and proximal right humerus, 2) both hands, 3) both knees, 4) left humerus with a total dose of 40 Gy in 2.0 or 2.5 Gy daily fractions. Results: Different results of pain palliation were achieved. In one location the pain was reduced for 55 months until her death due to disease progression, whereas in two other locations a pain control was maintained for 3 and 6 months after radiotherapy. In one location, no pain reduction was achieved. Severe side effects were not observed. Conclusion: Palliative radiotherapy has a role in the control of severe intractable bone pain in patients with advanced SMCD, though in some cases the effect may be short or incomplete. The observed palliation of pain can even differ in the same patient. (orig.)

    Full Text Available Disodium pamidronate (Aredia®, a drug of the bisphosphonate group, was administered to 20 patients with pains in the bones due to secondary deposits of lung cancer. The aim of the study was to investigate the analgesic effect of pamidronate to osteolytic metastases of lung cancer in the bone. In 16 (80% patients non-small-cell lung cancer was diagnosed, and in 4 (20% patients small-cell-lung cancer was confirmed. Intensive disseminated pains in the bones were present in all the patients. Metastases in the skeleton were confirmed by radiography and scintigraphy of the bones. Initial values of calcium in the plasma were determined in those patients. In 11 (55% patients, initial values of calcium in the serum were normal, and in 9 (45% patients, they were elevated. Patients with normal calcium values received 30 mg of pamidronate in 250 ml of normal saline, and patients with hypercalcaemia received 45-60 mg in 500 ml of normal saline. Analgesic effect of pamidronate was present in 12 (60% patients, and the completely painless state was achieved in 4 out of 12 patients. Evaluation of the pain was done by questionnaire, using a simple, descriptive scale. In all 9 (100% patients with hypercalcaemia, values of calcium in plasma were normalized. Pamidronate exerted favorable analgesic effect in the case of metastases of lung cancer in the bones in more than 50% patients. Satisfactory results were also achieved in the patients non-responsive to palliative therapy by irradiation This enables the use of opiates in lower doses.

    Full Text Available Breast cancer is one of the most prevalent cancers amongst women in the world. Unfortunately, even after adequate treatment, some patients experience severe pain either due to disease progression or due to treatment related side effects. The persistent pain causes a negative physical and psychosocial impact on patients′ lives. Current rational pain management is patient-centred and requires a thorough psychological assessment. Usually adequate analgesia is achieved by adopting the WHO′s three step analgesic ladder. As the disease progresses, the pain experienced by the patient also increases. This necessitates the administration of opioids and adjuvant analgesics to the breast cancer patients experiencing severe pain. However, opioid use is associated with intolerable side effects like constipation, nausea, vomiting, fear of dependence, and tolerance. Concomitant medications are required to combat these unacceptable side effects. Adjuvant analgesics need to be added to provide adequate and satisfactory analgesia. These factors worsen the psychological state of patients and deteriorate their quality of life. Hence, there is a need to develop therapeutic modalities to provide adequate analgesia with minimum side effects. This review article focuses on the current treatments available for cancer pain management, their limitations, and novel targets and non-pharmacological measures under investigation which have the potential to produce a radical change in pain management measures for the breast cancer patients.

    Prostate cancer is the most common primary tumor in men, with a high propensity to metastasize to bone. Bone metastases in prostate cancer are associated with active pathologic bone remodeling, leading to increased mortality and morbidity. Detailed characterization of bone metastases is important in the management of prostate cancer. Raman spectroscopy was applied in this study to investigate the structure and composition of metastatic bone in prostate cancer with the ultimate goal of identifying spectral features that are related to the alterations in bone quality as the bone metastases develop. Osteoblastic-, osteolytic- and tumor-absent bone specimens from prostate cancer patients were investigated using bench-top Raman microspectroscopy. Raman derived measurements of collagen mineralization, mineral crystallinity, and carbonate substitution were calculated. The osteolytic lesions demonstrated significantly lower collagen mineralization, determined by phosphate ν1/proline, and higher carbonate substitution than normal and osteoblastic bones. Mineral crystallinity was significantly lower in both blastic and lytic specimens. In addition, a significant increase in the ratio of hydroxyproine: proline was observed in the osteoblastic specimen, indicating an increase in the content of hydroxyproline at the blastic lesions. This study demonstrate that Raman spectroscopy shows promise in determining alterations in osteoblastic and osteolytic bone metastases as well as assessing the response of metastatic bone to therapies.

    Breakthrough pain is defined as an acute exacerbation of pain with rapid onset, short duration and moderate or high intensity, which occurs spontaneously or in connection with a predictable or unpredictable event despite there being stabilised and controlled baseline pain. However, there are doubts about the definition, terminology, epidemiology, and assessment of breakthrough pain, with no clear answers or consensus, especially in the elderly population. This non-systematic review summarises the most important aspects of breakthrough pain in the elderly, based on the limited publications there are in that population group.

    Metastatic prostate cancer has a unique predilection for bone that can lead to significant clinical sequelae, such as fracture and cord compression. This tropism for bone yields not only clinical challenges, but also opportunities to understand the tumor biology in bone and to develop relevant therapeutic strategies. The process by which tumor cells migrate to bone, remain dormant, and then colonize and expand is based on complex interactions between prostate cancer tumor cells and the host microenvironment. This review will provide an overview of these interactions as well as therapies targeting osseous metastases in castration-resistant prostate cancer.

    @@ Bone is one of the most preferential target sites for cancers such as breast, prostate and lung cancers to metastasize. Although the mechanism under-lying this organ preference still needs to be elucidated, observations that specific inhibitors of osteoclasts such as bisphosphonates inhibit bone metastases suggest a critical role of osteoclasts.

  5. Opioids for cancer pain: the challenge of optimizing treatment.

    During 2007, 11.7 million US men and women of all ages suffered from some form of invasive cancer. During their illness, at least 70% (8.2 million) will experience pain sufficiently severe to require chronic opioid treatment. Cancer-induced pain is usually described under 3 headings: acute pain, chronic pain, and breakthrough pain. Among patients with chronic, persistent cancer pain controlled by around-the-clock analgesics, there is a high prevalence of breakthrough pain-often precipitated by some form of physical activity. Breakthrough pain seems best treated by a powerful, fast-acting opioid such as intravenous morphine or transmucosal fentanyl. At present, opioids are virtually the only analgesics capable of controlling moderate and severe cancer pain. In recent years, a veritable arsenal of opioids with a wide range of pharmacologic properties has become available for use in different pain situations. The World Health Organization has developed a 3-step "analgesic ladder" to guide management of cancer pain, based on the pain's severity, estimated by means of a 1 to 10 numeric rating scale. As the severity of the pain escalates, more potent (World Health Organization Step III) opioids are used. When faced with a difficult case of cancer pain, the physician must choose-from an array of options-the safest and most effective opioid analgesic and the most appropriate delivery system. Such decisions require an adequate understanding of the available opioids and experience with their use. The pharmacodynamic response to a given opioid depends on the nature of the receptor to which the opioid binds and its affinity for the receptor. Morphine activates the μ-opioid receptors, resulting in not only analgesia and sedation, but also euphoria, respiratory depression, constipation, and pruritus. The existence of a number of opioid receptor subtypes, each with its own repertoire of responses, has given rise to the hope (as yet unrealized) that an opioid can be found (or

    Data on the prevalence of bone cancer in dinosaurs is available from past radiological examination of preserved bones. We statistically test this data for consistency with rates extrapolated from information on bone cancer in modern vertebrates, and find that there is no evidence of a different rate. Thus, this test provides no support for a possible role of ionizing radiation in the K-T extinction event.

    Skeletal complications are a common cause of morbidity in patients with primary bone cancer and bone metastases. The type 2 cannabinoid (Cnr2) receptor is implicated in cancer, bone metabolism and pain perception. Emerging data have uncovered the role of Cnr2 in the regulation of tumour-bone cell interactions and suggest that agents that target Cnr2 in the skeleton have potential efficacy in the reduction of skeletal complications associated with cancer. This review aims to provide an overview of findings relating to the role of Cnr2 receptor in the regulation of skeletal tumour growth, osteolysis and bone pain, and highlights the many unanswered questions and unmet needs. This review argues that development and testing of peripherally-acting, tumour-, Cnr2-selective ligands in preclinical models of metastatic cancer will pave the way for future research that will advance our knowledge about the basic mechanism(s) by which the endocannabinoid system regulate cancer metastasis, stimulate the development of a safer cannabis-based therapy for the treatment of cancer and provide policy makers with powerful tools to assess the science and therapeutic potential of cannabinoid-based therapy. Thus, offering the prospect of identifying selective Cnr2 ligands, as novel, alternative to cannabis herbal extracts for the treatment of advanced cancer patients.

    Pain associated with cancer that metastasizes to bone is often severe and debilitating. A better understanding of the neural mechanisms that mediate cancer pain is needed for the development of more effective treatments. In this study, we used an established model of cancer pain to characterize changes in response properties of dorsal horn neurons. Fibrosarcoma cells were implanted into and around the calcaneus bone in mice and extracellular electrophysiological recordings were made from wide dynamic range (WDR) and high threshold (HT) dorsal horn neurons. Responses of WDR and HT neurons evoked by mechanical, heat, and cold stimuli applied to the plantar surface of the hind paw were compared between tumor bearing mice and control mice. Mice exhibited hyperalgesia to mechanical and heat stimuli applied to their tumor-bearing hind paw. WDR neurons in tumor-beating mice exhibited an increase in spontaneous activity, and enhanced responses to mechanical, heat, and cold stimuli as compared to controls. Our findings show that sensitization of WDR neurons, but not HT neurons, contributes to tumor-evoked hyperalgesia.

    This study examines the relationship of personality traits and affect on cancer-related pain in 150 older adults receiving outpatient treatment at a comprehensive cancer center. Regression analyses revealed extraversion as a significant predictor of current pain, with openness to experience as a significant indicator of average pain. Similarly, positive affect and negative affect were significant predictors of self-efficacy for pain management. Moderation models showed that conscientiousness and extraversion were significant moderators in the relationship between self-efficacy for pain management and worst pain. These findings suggest that different personality types may influence perceptions of pain severity.

    Objective To explore the analgesia effects of quinpirole ( QNP ) via intrathecal injection and its influence on spi-nal microglia activation in rats with bone cancer pain. Methods Sixty adult male SD rats were used to establish bone cancer pain mod-el by intra-tibia inoculation of Walker256 mammary gland carcinoma cells. The rats with bone cancer pain were randomly divided into 3 groups:high-dose QNP ( QNP-H) group, low-dose QNP ( QNP-L) group and normal saline ( NS) group, with 20 rats in each group. QNP-H group and QNP-L group received intrathecal injection of 10μl QNP at the dose of 10 and 5μg/kg, respectively. Another 20 male SD rats were chosen as control ( C) group and received the same volume of saline as NS group. Pain behaviors were assessed be-fore treatment and 1, 3, 5 and 7d during treatment to analyze the paw mechanical withdrawal threshold ( MWT) and paw withdrawal thermal latency ( WTL) . The immunohistochemistry was employed to evaluate the spinal microglia number ionized calcium binding ada-ptor molecule 1 and activation by the integral optical density ( IOD) of C3 complement receptor ( OX-42) and cannabinoid receptor 2 ( CB2) . The spinal levels of TNF-αand IL-1βwere measured by enzyme linked immunosorbent assay. Moreover, the protein levels of spinal Toll like receptor-4 ( TLR-4) and its receptor-2 ( TLR-2) were detected by Western blotting. Results Compared with C group, there were lower MWT and WTL, but higher spinal microglia number, IOD of OX-42 and CB2, TNF-α, IL-1β, TLR-2 and TLR-4 in NS, QNP-L and QNP-H groups with significant difference ( P<0. 05) . Intrathecal injection of QNP improved the above abnormalities of rats with bone cancer pain compared with NS group ( P<0. 05) . The effect of QNP-H group was stronger than that of QNP-L group ( P<0. 05) . Conclusion Intrathecal injection of QNP exhibits a good analgesic effect on bone cancer pain and inhibits spinal microglia ac-tivation and inflammatory reaction.%目的:探讨鞘内

    2015-12-01

    Buprenorphine (BUP) is a semisynthetic derivative of the opium alkaloid thebaine found in the poppy Papaver somniferum. Its chemical structure contains the morphine structure but differs by having a cyclopropylmethyl group. Buprenorphine is a potent µ opioid agonist. Buprenorphine undergoes extensive first-pass metabolism in the liver and gut. The development of a transdermal BUP formulation in 2001 led to its evaluation in cancer pain. This article provides the practitioner with an update on the current role of BUP in cancer care. It highlights data suggesting effectiveness in various types of cancer pain. The article reviews pharmacology, routes of administration, adverse effects, drug interactions, and cost considerations.

  12. The physiology of bone pain. How much do we really know?

    Directory of Open Access Journals (Sweden)

    Sara eNencini

    2016-04-01

    Full Text Available Pain is associated with most bony pathologies. Clinical and experimental observations suggest that bone pain can be derived from noxious stimulation of the periosteum or bone marrow. Sensory neurons are known to innervate the periosteum and marrow cavity, and most of these have a morphology and molecular phenotype consistent with a role in nociception. However, little is known about the physiology of these neurons, and therefore information about mechanisms that generate and maintain bone pain is lacking. The periosteum has received greater attention relative to the bone marrow, reflecting the easier access of the periosteum for experimental assessment. With the electrophysiological preparations used, investigators have been able to record from single periosteal units in isolation, and there is a lot of information available about how they respond to different stimuli, including those that are noxious. In contrast, preparations used to study sensory neurons that innervate the bone marrow have been limited to recording multi-unit activity in whole nerves, and whilst they clearly report responses to noxious stimulation, it is not possible to define responses for single sensory neurons that innervate the bone marrow. There is only limited evidence that peripheral sensory neurons that innervate bone can be sensitized or that they can be activated by multiple stimulus types, and at present this only exists in part for periosteal units. In the central nervous system, it is clear that spinal dorsal horn neurons can be activated by noxious stimuli applied to bone. Some can be sensitized under pathological conditions and may contribute in part to secondary or refered pain associated with bony pathology. Activity related to stimulation of sensory nerves that innervate bone has also been reported in neurons of the spinoparabrachial pathway and the somatosensory cortices, both known for roles in coding information about pain. Whilst these provide some clues

    2016-11-01

    Full Text Available A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease. From the cervical, thoracic and abdominal computed tomography images, there were no metastatic lesions except for the bone lesions. To confirm whether the bone lesions were metastatic, we performed bone biopsy. The histopathological diagnosis was bone marrow hyperplasia. It was crucial for treatment planning to establish whether the lesions were distant metastases. Here, we report a case of esophageal cancer with bone marrow hyperplasia mimicking bone metastasis.

    Bone metastases are a major problem in the clinical management of patients with prostate cancer. Despite the use of analgesic for the relief of such pain, the outcomes are not often satisfactory. Strontium-89 (89Sr) is a pure beta-emitting radioisotope to be avidly concentrated in the areas of high osteoblastic activity. The aim of this study was to evaluate the efficacy of 89Sr in the therapy for bone metastases of prostate carcinoma. 116 patients received intravenous injection of 89Sr at the dose of 3mCi (111MBq). All patients underwent physical examination and Karnofsky's Performance Score (KPS) evaluation before and after administration; the analgesic effects were evaluated by scores of pain. The complete response (CR) was defined as scores of pain > 75%; no response (NR) was defined as scores of pain bone metastases were screened by CT, MRI and 99mTc-MDP bone scintigraphy according to the standards of WHO. After the treatment with 89Sr, the total response rate was 80.2%. In the 116 cases, 21 cases (18.1%) displayed complete response and 72 cases (62.1%) displayed partial response, but 23 cases (19.2%) showed no response. The mean score on Karnfsky's performance status (KPS) was 20.0% higher. About 1/3 cases exhibited an obvious decrease in the number of metastases, and some foci disappeared. Thirteen cases (12%) showed a greater decrease in prostate-specific antigen (PSA) value. 89Sr chloride is an effective and safe therapy of the bone metastases from prostate cancer.

    The objective of this study was to demonstrate the efficacy, safety and patient acceptability of the use of intranasal sufentanil for cancer-associated breakthrough pain. This was a prospective, open label, observational study of patients in three inpatient palliative care units in Australia. Patients on opioids with cancer-associated breakthrough pain and clinical evidence of opioid responsiveness to their breakthrough pain were given intranasal (IN) Sufentanil via a GO Medical patient controlled IN analgesia device. The main outcome measures were pain scores, need to revert to previous breakthrough opioid after 30 min, number of patients who chose to continue using IN sufentanil, and adverse effects. There were 64 episodes of use of IN sufentanil for breakthrough pain in 30 patients. There was a significant reduction in pain scores at 15 (P < 0.0001) and 30 min (P < 0.0001). In only 4/64 (6%) episodes of breakthrough pain did the participants choose to revert to their prestudy breakthrough medication. Twenty-three patients (77%) rated IN sufentanil as better than their prestudy breakthrough medication. The incidence of adverse effects was low and most were mild. Our study showed that IN sufentanil can provide relatively rapid onset, intense but relatively short lasting analgesia and in the palliative care setting it is an effective, practical, and safe option for breakthrough pain.

    Full Text Available The objective of this study was to evaluate pain in women with breast cancer-related lymphedema and the characteristics of aggravating factors and coping mechanisms. The study was conducted in the Clinica Godoy, São Jose do Rio Preto, with a group of 46 women who had undergone surgery for the treatment of breast cancer. The following variables were evaluated: type and length of surgery; number of radiotherapy and chemotherapy sessions; continued feeling of the removed breast (phantom limb, infection, intensity of pain, and factors that improve and worsen the pain. The percentage of events was used for statistical analysis. About half the participants (52.1% performed modified radical surgery, with 91.3% removing only one breast; 82.6% of the participants did not perform breast reconstruction surgery. Insignificant pain was reported by 32.60% of the women and 67.3% said they suffered pain; it was mild in 28.8% of the cases (scale 1–5, moderate in 34.8% (scale 6–9, and severe in 4.3%. The main mechanisms used to cope with pain were painkillers in 41.30% of participants, rest in 21.73%, religious ceremonies in 17.39%, and chatting with friends in 8.69%. In conclusion, many mastectomized patients with lymphedema complain of pain, but pain is often underrecognized and undertreated.

    Full Text Available Prostate cancer bone metastases are associated with a poor prognosis and are considered incurable. Insight into the formation and growth of prostate cancer bone metastasis is required for development of new imaging and therapeutic strategies to combat this devastating disease. Animal models are indispensable in investigating cancer pathogenesis and evaluating therapeutics. Multiple animal models of prostate cancer bone metastasis have been developed, but few effectively model prostatic neoplasms and osteoblastic bone metastases as they occur in men. This review discusses the animal models that have been developed to investigate prostate cancer bone metastasis, with a focus on canine models and also includes human xenograft and rodent models. Adult dogs spontaneously develop benign prostatic hyperplasia and prostate cancer with osteoblastic bone metastases. Large animal models, such as dogs, are needed to develop new molecular imaging tools and effective focal intraprostatic therapy. None of the available models fully reflect the metastatic disease seen in men, although the various models have provided important insight into the metastatic process. As additional models are developed and knowledge from the different models is combined, the molecular mechanisms of prostate cancer bone metastasis can be deciphered and targeted for development of novel therapies and molecular diagnostic imaging.

    Full Text Available Breast cancer is one of the leading causes of cancer death among women of all races. Pain is a common symptom associated with cancer; 75–90% of cancer patients experience pain during their illness and up to 50% of that pain is undertreated. Unrelieved pain leads to increased levels of the stress hormone cortisol. The purpose of this study was to examine the impact of bioenergy on fecal cortisol levels for mice injected with murine mammary carcinoma 4T1 in two separate pilot studies. Using a multiple experimental group design, six to eight week old female BALB/c mice were injected with tumor and randomly assigned, in groups of 10, to daily treatment, every other day treatment, and no treatment groups. Five days after tumor cell injection, bioenergy interventions were begun for a period of ten consecutive days. Fecal samples were collected for each study and ELISA analysis was conducted at the end of both studies. For both studies, cortisol levels were decreased in the every other day treatment groups but remained high in the no treatment groups. Future studies utilizing bioenergy therapies on cortisol levels in a murine breast cancer model can begin to describe pain outcomes and therapeutic dose.

    Many people with cancer will experience pain when they are outside of structured care settings. Patients must provide their own self-care, drawing on instructions from healthcare providers and on independently developed plans for pain management. With growing interest in complementary therapies, the scope of nonpharmacologic interventions used by patients with cancer to manage pain may be very different than 10-15 years ago. The purpose of this study was to describe steps taken by patients with breast and gynecologic cancer to manage pain after discharge from a surgical hospitalization. A secondary analysis was completed using data from 34 women who participated in a randomized trial of guided imagery. Techniques used included positioning, distraction, relaxation, heat, and eating/drinking. Compared to results of previous studies, increased use of relaxation strategies (breathing, imagery, music, meditation) was noted in the current study. The majority of participants used nonpharmacologic strategies in addition to analgesic medications. Pain-related outcomes were similar among persons who used analgesic medications alone and those who used a combination of analgesics and nonpharmacologic strategies. Nurses may benefit from knowing which pain management strategies patients find helpful so that they can encourage their use and teach similar strategies to the patients who find them useful.

    INTRODUCTION: Every year 4000 women in Denmark undergo surgery for breast cancer. According to published literature approximately 50% suffer from post-operative nausea and vomiting (PONV) and moderate pain. No national guidelines are available regarding the treatment or prevention of pain and PONV...... associated with surgery for these patients. MATERIALS AND METHODS: 116 consecutive patients scheduled for breast cancer surgery were prospectively scored according to pain, PONV and sedation after being introduced to a combined evidence-based, empiric multimodal opioid-sparing prevention and treatment regime...... severe PONV and vomiting resistant to treatment. Upon arrival at the recovery 15% of the patients were in a state of moderate to severe sedation. This number was 1.5% 75 minutes later. CONCLUSION: It is possible with a multimodal opioid-sparing prevention and treatment regime for pain and PONV to gain...

    To evaluate the effectiveness of percutaneous radiofrequency (RF) ablation with or without percutaneous vertebroplasty (PV) on pain relief, functional recovery and local recurrence at 6 months' follow-up (FU), in patients with painful osseous metastases. Thirty RF ablations were performed in 24 patients (mean age: 61 years) with bone metastases. Half of the patients had an additional PV. The primary end point was pain relief evaluated by a visual analogue scale (VAS) before treatment, and at 1 and 6 months' FU. Functional outcome was assessed according to the evolution of their ability to walk at 6 months' FU. Imaging FU was available in 20 out of 24 patients with a mean delay of 4.7 months. Reduction of pain was obtained at 6 months FU in 81% of cases (15 out of 18). Mean pretreatment VAS was 6.4 ({+-}2.7). Mean VAS was 1.9 ({+-}2.4) at 1 month FU, and 2.3 ({+-}2.9) at 6 months' FU. Pain was significantly reduced at 6 months FU (mean VAS reduction = 4.1; P < 0.00001). Functional improvement was obtained in 74% of the cases. Major complications rate was 12.5 % (3 out of 24) with 2 skin burns, and 1 case of myelopathy. Local tumour recurrence or progression was recorded in 5 cases. Radiofrequency ablation is an effective technique in terms of pain relief and functional recovery for the treatment of bone metastases, which provides a relatively low rate of local recurrence.

    Cachexia is a distinctive feature of colorectal cancer associated with body weight loss and progressive muscle wasting. Several mechanisms responsible for muscle and fat wasting have been identified, however it is not known whether the physiologic and molecular crosstalk between muscle and bone tissue may also contribute to the cachectic phenotype in cancer patients. The purpose of this study was to clarify whether tumor growth associates with bone loss using several experimental models of colorectal cancer cachexia, namely C26, HT-29, and ApcMin/+. The effects of cachexia on bone structure and strength were evaluated with dual energy X-ray absorptiometry (DXA), micro computed tomography (μCT), and three-point bending test. We found that all models showed tumor growth consistent with severe cachexia. While muscle wasting in C26 hosts was accompanied by moderate bone depletion, no loss of bone strength was observed. However, HT-29 tumor bearing mice showed bone abnormalities including significant reductions in whole-body bone mineral density (BMD), bone mineral content (BMC), femoral trabecular bone volume fraction (BV/TV), trabecular number (Tb.N), and trabecular thickness (Tb.Th), but no declines in strength. Similarly, cachexia in the ApcMin/+ mice was associated with significant decreases in BMD, BMC, BV/TV, Tb.N, and Tb.Th as well as decreased strength. Our data suggest that colorectal cancer is associated with muscle wasting and may be accompanied by bone loss dependent upon tumor type, burden, stage and duration of the disease. It is clear that preserving muscle mass promotes survival in cancer cachexia. Future studies will determine whether strategies aimed at preventing bone loss can also improve outcomes and survival in colorectal cancer cachexia. PMID:28123369

    It has been reported that remarkable and sustained activation of astrocytes and/or microglia occurs in cancer induced pain (CIP), which is different from neuropathic and inflammatory pain. The present study was designed to investigate the role of spinal Toll-like receptor 4 (TLR4) induced glial neuroinflammation in cancer induced pain using a modified rat model of bone cancer. The rat model of CIP consisted of unilateral intra-tibial injection with Walker 256 mammary gland carcinoma. Nine days after Walker 256 inoculation, a robust activation of both astrocytes and microglia in bilateral spinal dorsal horn was observed together with significant bilateral mechanical allodynia. This neuroinflammation was characterized by enhanced immunostaining of both glial fibrillary acidic protein (GFAP, astrocyte marker) and OX-42 (microglia marker), and an elevated level of IL-1β, IL-6 and TNF-α mRNA. I.t. administration of fluorocitrate (an inhibitor of glial metabolism, 1 nmol) or minocycline (an inhibitor of microglia, 100 μg) has significant anti-allodynic effects on day 12 after Walker 256 inoculation. Naloxone (a nonstereoselective TLR4 signaling blocker, 60 μg, i.t.) also significantly alleviated mechanical allodynia and simultaneously blocked the increased inflammatory cytokine mRNA. The results suggested that spinal TLR4 might play an important role in the sustained glial activation that critically contributed to the robust and sustained spinal neuroinflammation in CIP. This result could potentially help clinicians and researchers to better understand the mechanism of complicated cancer pain.

  15. Integrated multimodal imaging of dynamic bone-tumor alterations associated with metastatic prostate cancer.

    Directory of Open Access Journals (Sweden)

    Jean-Christophe Brisset

    Full Text Available Bone metastasis occurs for men with advanced prostate cancer which promotes osseous growth and destruction driven by alterations in osteoblast and osteoclast homeostasis. Patients can experience pain, spontaneous fractures and morbidity eroding overall quality of life. The complex and dynamic cellular interactions within the bone microenvironment limit current treatment options thus prostate to bone metastases remains incurable. This study uses voxel-based analysis of diffusion-weighted MRI and CT scans to simultaneously evaluate temporal changes in normal bone homeostasis along with prostate bone metatastsis to deliver an improved understanding of the spatiotemporal local microenvironment. Dynamic tumor-stromal interactions were assessed during treatment in mouse models along with a pilot prospective clinical trial with metastatic hormone sensitive and castration resistant prostate cancer patients with bone metastases. Longitudinal changes in tumor and bone imaging metrics during delivery of therapy were quantified. Studies revealed that voxel-based parametric response maps (PRM of DW-MRI and CT scans could be used to quantify and spatially visualize dynamic changes during prostate tumor growth and in response to treatment thereby distinguishing patients with stable disease from those with progressive disease (p<0.05. These studies suggest that PRM imaging biomarkers are useful for detection of the impact of prostate tumor-stromal responses to therapies thus demonstrating the potential of multi-modal PRM image-based biomarkers as a novel means for assessing dynamic alterations associated with metastatic prostate cancer. These results establish an integrated and clinically translatable approach which can be readily implemented for improving the clinical management of patients with metastatic bone disease.

    Full Text Available CONTEXT: Visceral pain characterizing pancreatic cancer is the most difficult symptom of the disease to control and can significantly impair the quality of life which remains and increase the demand for euthanasia. AIM: To investigate a possible new method based on biophysical principles (scrambler therapy to be used in the effective treatment of drug-resistant oncological pain of the visceral/neuropathic type. SETTING: Eleven terminal cancer patients (3 pancreas, 4 colon, 4 gastric suffering from elevated drug resistant visceral pain. DESIGN: The trial program was related to the first ten treatment sessions. Subsequently, each patient continued to receive treatment until death. MAIN OUTCOME MEASURES: Pain measures were performed using the visual analogue scale before and after each treatment session and accompanied by diary recordings of the duration of analgesia in the hours following each single application. Any variation in pain-killing drug consumption was also recorded. RESULTS: All patients reacted positively to the treatment throughout the whole reference period. Pain intensity showed a significant decrease (P less than 0.001, accompanied by a gradual rise both in the pain threshold and the duration of analgesia. Nine (81.8% of the patients suspended pain-killers within the first 5 applications, while the remaining two (18.2% considerably reduced the dosage taken prior to scrambler therapy. No undesirable side effects were observed. Compliance was found to be optimal. CONCLUSIONS: The preliminary results obtained using scrambler therapy are extremely encouraging, both in terms of enhanced pain control after each treatment session and in view of the possible maintenance of effectiveness over time.

    We present a 21-year-old woman with a short history of pelvic pain. The history was unremarkable apart from that of undergoing a surgical termination of pregnancy (TOP) some three-and-half years ago. Examination revealed a foreign body at the cervical os. Subsequent investigations revealed more foreign bodies within the cervical canal and uterine cavity, which were removed. Histologically these were found to be bones. Removal of the bone fragment initially discovered lead to an improvement of symptoms. Although the patient was treated for pelvic-inflammatory disease, no infective cause could be established. The condition of intrauterine retained fetal bones is recognized, but rare. Patients experiencing pelvic pain usually present sooner after TOP than did this patient. Although rare, it is an important condition to diagnose as it represents a treatable cause of infertility.

    Since breast cancer is frequently associated with bone metastasis, bone scintigraphies have been performed to determine pre-operative staging and to survey postoperative bone metastasis. The sternum, in particular, is a site at which is difficult to differentiate between benign bone disease and bone metastasis, because of varied uptake and wide individual variations. In this study, chronological bone images were scintigraphied in six cases with solitary sternal metastasis and three cases with benign bone disease including two fracture cases and one arthritis case. On bone scintigrams in which solitary sternal metastasis appeared, increased uptake was found in five cases, and photon deficiency was observed in one case. During follow-up scintigraphies, abnormal accumulations, such as hot spots and cold lesions, increased in the bone metastasis while abnormal uptake disappeared or was unchanged in the benign bone disease cases. On CT, four cases showed osteolytic change, and one exhibited osteosclerotic change. These findings indicate that sternal metastasis usually shows osteolytic change, even if a hot lesion is recognized on bone scintigraphy. In solitary sternal metastasis, for which early diagnosis is difficult, both an integrated diagnosis using other imaging techniques and chronological bone scintigraphy are important. (author)

    The cannabinoid type 2 receptor (CB2) has previously been implicated as a regulator of tumor growth, bone remodeling, and bone pain. However, very little is known about the role of the skeletal CB2 receptor in the regulation of osteoblasts and osteoclasts changes associated with breast cancer. Here we found that the CB2-selective agonists HU308 and JWH133 reduced the viability of a variety of parental and bone-tropic human and mouse breast cancer cells at high micromolar concentrations. Under conditions in which these ligands are used at the nanomolar range, HU308 and JWH133 enhanced human and mouse breast cancer cell-induced osteoclastogenesis and exacerbated osteolysis, and these effects were attenuated in cultures obtained from CB2-deficient mice or in the presence of a CB2 receptor blocker. HU308 and JWH133 had no effects on osteoblast growth or differentiation in the presence of conditioned medium from breast cancer cells, but under these circumstances both agents enhanced parathyroid hormone-induced osteoblast differentiation and the ability to support osteoclast formation. Mechanistic studies in osteoclast precursors and osteoblasts showed that JWH133 and HU308 induced PI3K/AKT activity in a CB2-dependent manner, and these effects were enhanced in the presence of osteolytic and osteoblastic factors such as RANKL (receptor activator of NFκB ligand) and parathyroid hormone. When combined with published work, these findings suggest that breast cancer and bone cells exhibit differential responses to treatment with CB2 ligands depending upon cell type and concentration used. We, therefore, conclude that both CB2-selective activation and antagonism have potential efficacy in cancer-associated bone disease, but further studies are warranted and ongoing.

    Full Text Available Morphine has been used for many years to relieve cancer pain. Oral morphine (in either immediate release or modified release form remains the analgesic of choice for moderate or severe cancer pain. The dose of oral morphine is titrated up to achieve adequate relief from pain with minimal side effects. Antidepressant and anticonvulsant drugs, when used in addition to conventional analgesics, give excellent relief from cancer pain. Most cancer pain responds to pharmacological measures with oral morphine but some pain like neuropathic and bony pain, pain in children and elderly age group, and advanced malignancy pain are very difficult to treat. Here, we report the management of a similar patient of severe cancer pain and the difficulty that we came across during dose titration of oral morphine and adjuvant analgesic.

    Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is a novel treatment method that achieves non-invasive thermal ablation by focusing many ultrasound waves on a target tissue with real-time monitoring of the location and temperature of the target during the procedure. We investigated the palliative effect on pain and safety of MRgFUS in painful bone metastases. Six patients (mean age, 65.8 years) who met eligibility criteria for the clinical study approved by our Institutional Ethics Committee based on the cooperative protocol were treated with MRgFUS. Targeted sites included the sacrum (n = 1), ilium (n = 2), scapula (n = 2), and femur (n = 1). The mean follow-up period was 9.2 months. All procedures were performed as a single-session treatment using the treatment system that is integrated into the patient table of a magnetic resonance image (MRI) scanner. Endpoints were change in the intensity of pain due to bone metastases from before to after the treatment, as measured on a numerical rating scale, pain interference with daily activities as determined by the Brief pain inventory (BPI), change in images, and safety. Pain relief was obtained in all patients early after treatment, with a reduction in the mean pain score from 6.0±1.3 at baseline to 1.2±1.0 at the end of follow-up as well as in pain interference with daily activities. The mean time required for a single-session treatment was 83.7±37.0 min, with a mean number of sonications required of 13.3±3.7 and mean energy applied of 846.4±273.5 J. No significant growth of tumors was observed, nor were there treatment-related adverse events. These results suggest that MRgFUS has a non-invasive palliative effect on the localized pain in patients with bone metastasis. MRgFUS could become an option in treatment strategies for painful bone metastases in the future.

    Bone metastases and skeletal complications are major causes of morbidity in prostate cancer patients. Despite the osteoblastic appearance of bone metastases on imaging studies, patients have elevated serum and urinary markers of bone resorption, indicative of high osteoclast activity. Increased osteoclast activity is independently associated with higher risk of subsequent skeletal complications, disease progression, and death. Osteoclast-targeted therapies are therefore a rational approach to reduction of risk for disease-related skeletal complications, bone metastases, and treatment-related fractures. This review focuses on recent advances in osteoclast-targeted therapy in prostate cancer. Bisphosphonates have been extensively studied in men with prostate cancer. Zoledronic acid significantly decreased the risk of skeletal complications in men with castration-resistant prostate cancer and bone metastases, and it is FDA-approved for this indication. Denosumab is a human monoclonal antibody that binds and inactivates RANKL, a critical mediator of osteoclast differentiation, activation, and survival. Recent global phase 3 clinic trials demonstrated an emerging role for denosumab in the treatment of prostate cancer bone metastases and prevention of fractures associated with androgen deprivation therapy.

  17. Bone targeted therapies for the prevention of skeletal morbidity in men with prostate cancer

    Institute of Scientific and Technical Information of China (English)

    Philip J Saylor

    2014-01-01

    Men with prostate cancer suffer substantially from bone-related complications. Androgen deprivation therapy itself is a cause of loss of bone mineral density and is associated with an increased incidence of osteoporotic fractures. In advanced disease, bone is by far the most common site of metastasis. Complications of bone metastases prominently include pain and the potential for skeletal events such as spinal cord compression and pathologic fractures. Elevated osteoclast activity is an important aspect of the pathophysiology of both treatment-related osteoporosis and skeletal complications due to metastases. The osteoclast is therefore a therapeutic target. Denosumab is a fully human monoclonal antibody to receptor activator of nuclear factor-k-B ligand that was designed to potently inhibit osteoclast activity and is the central focus of this review. Bisphosphonates, radiopharmaceuticals and systemically-active hormonal agents such as abiraterone acetate and enzalutamide have each been shown to improve skeletal morbidity in speciifc clinical situations. Denosumab is the only agent that has been shown to prevent osteoporotic fractures in men receiving androgen deprivation therapy and at elevated risk for fracture. It has also demonstrated superiority to the potent bisphosphonate zoledronic acid for the prevention of skeletal-related events in men with castration-resistant prostate cancer metastatic to bone. Efifcacy and toxicity data will be discussed.

    To evaluate the MR imaging findings of painful type II accessory navicular bone and to correlate these with the surgical and pathologic findings. The MR images of 17 patients with medial foot pain and surgically proven type II accessory navicular abnormalities were reviewed. The changes of signal intensity in the accessory navicular, synchondrosis and adjacent soft tissue, the presence of synchondrosis widening, and posterior tibial tendon (PTT) pathology on the T1-weighted and fat-suppressed T2-weighted images were analyzed. The MR imaging findings were compared with the surgical and pathologic findings. The fat-suppressed T2-weighted images showed high signal intensity in the accessory navicular bones and synchondroses in all patients, and in the soft tissue in 11 (64.7%) of the 17 patients, as well as synchondrosis widening in 3 (17.6%) of the 17 patients. The MR images showed tendon pathology in 12 (75%) of the 16 patients with PTT dysfunction at surgery. The pathologic findings of 16 surgical specimens included areas of osteonecrosis with granulomatous inflammation, fibrosis and destruction of the cartilage cap. The MR imaging findings of painful type II accessory navicular bone are a persistent edema pattern in the accessory navicular bone and within the synchondrosis, indicating osteonecrosis, inflammation and destruction of the cartilage cap. Posterior tibial tendon dysfunction was clinically evident in most patients.

  20. Characterizing the inorganic/organic interface in cancer bone metastasis

    Science.gov (United States)

    Wu, Fei

    Bone metastasis frequently occurs in patients with advanced breast cancer and remains a major source of mortality. At the molecular level, bone is a nanocomposite composed of inorganic bone mineral deposited within an organic extracellular matrix (ECM). Although the exact mechanisms of bone metastasis remain unclear, the nanoscale materials properties of bone mineral have been implicated in this process. Bone apatite is closely related to synthetic hydroxyapatite (HAP, Ca10(PO4)6(OH)2) in terms of structural and mechanical properties. Additionally, although the primary protein content of bone is collagen I, the glycoprotein fibronectin (Fn) is essential in maintaining the overall integrity of the bone matrix. Importantly, in vivo, neither breast cancer cells nor normal bone cells interact directly with the bone mineral but rather with the protein film adsorbed onto the mineral surface. Therefore, we hypothesized that breast cancer cell functions were regulated by differential fibronectin adsorption onto hydroxyapatite, which led to pathological remodeling of the bone matrix and sustained bone metastasis. Three model systems containing HAP and Fn were developed for this thesis. In model system I, a library of synthetic HAP nanoparticles were utilized to investigate the effect of mineral size, shape, and crystallinity on Fn conformation, using Forster resonance energy transfer (FRET) spectroscopy. In model system II, Fn-functionalized large geologic HAP crystals were used instead of HAP nanoparticles to avoid cellular uptake when investigating subsequent cell functions. Overall our FRET analysis (models I and II) revealed that Fn conformation depended on size, surface chemistry, and roughness of underlying HAP. When breast cancer cells were seeded on the Fn-coated HAP crystal facets (model II), our data indicated high secretion levels of proangiogenic and proinflammatory factors associated with the presence of unfolded Fn conformations, likely caused by differential

    Context Although minority patients with cancer pain are more likely to be undermedicated for cancer pain than non-Hispanic Whites, little is known about the experience of cancer pain in American Indians (AIs). Objectives To describe the experience of cancer and cancer pain in a sample of southwestern AIs. Methods Ethnographic interviews were conducted with 13 patients and 11 health care providers, caregivers, and community members; two questionnaires were used to collect demographic and pain data. Results Barriers to pain control among AIs included difficulties describing pain, a belief that cancer pain is inevitable and untreatable, and an aversion to taking opioid pain medication. Prescriber inexperience also was cited as a barrier to pain management. AIs described a strong desire to protect their privacy regarding their illness, and many felt that expressing pain was a sign of weakness. The inability to participate in spiritual and cultural activities caused AIs distress, and some discontinued treatment or missed chemotherapy appointments to engage in these activities. Conclusion Results revealed new knowledge about the cancer pain experience in AIs. The observation of the close relationship between treatment compliance and the patient’s ability to participate in ceremonial and spiritual activities provides new insight into the problem of incomplete cancer treatment in this population. The finding that AI patients have a multidimensional conceptualization of pain will assist clinicians with obtaining more detailed and informative pain assessments. PMID:22940564

    Bone marrow examination plays a crucial role in the diagnosis and management of various hematological and systemic diseases. Even though the procedure has been carried out for decades, it remains an extremely painful and uncomfortable experience for a majority of patients. This paper reviews the different strategies used to provide analgesia and summarizes the advantages and drawbacks of one strategy over the other. A literature review was carried out addressing the different approaches to providing pain relief during bone marrow aspiration and biopsy. Several different methods, procedure modifications and protocols are employed at various centers but pain control and analgesia remain incomplete. Local infiltration with lidocaine or similar local analgesics is the standard at most centers. Although there is limited data, there are several studies in literature demonstrating the pain relieving effects of different methods and drugs when used with local anesthetics. Sedation, usually using benzodiazepines, reduces anticipatory anxiety, provides analgesia and also short term amnesia. Combinations of different agents not only yield potent effects but also reduce the required dose of each individual drug, minimizing adverse effects. Non-pharmacological factors also play key roles. Providing patients with complete and comprehensible information is vital to ensure the least amount of discomfort during the biopsy. Distraction techniques, such as cognitive behavioral therapy, hypnosis and music therapy, may also play a role in minimizing pain.

    Advanced prostate cancer commonly metastasizes to bone, but transit of malignant cells across the bone marrow endothelium (BMEC) remains a poorly understood step in metastasis. Prostate cancer cells roll on E-selectin(+) BMEC through E-selectin ligand-binding interactions under shear flow, and prostate cancer cells exhibit firm adhesion to BMEC via β1, β4, and αVβ3 integrins in static assays. However, whether these discrete prostate cancer cell-BMEC adhesive contacts culminate in cooperative, step-wise transendothelial migration into bone is not known. Here, we describe how metastatic prostate cancer cells breach BMEC monolayers in a step-wise fashion under physiologic hemodynamic flow. Prostate cancer cells tethered and rolled on BMEC and then firmly adhered to and traversed BMEC via sequential dependence on E-selectin ligands and β1 and αVβ3 integrins. Expression analysis in human metastatic prostate cancer tissue revealed that β1 was markedly upregulated compared with expression of other β subunits. Prostate cancer cell breaching was regulated by Rac1 and Rap1 GTPases and, notably, did not require exogenous chemokines as β1, αVβ3, Rac1, and Rap1 were constitutively active. In homing studies, prostate cancer cell trafficking to murine femurs was dependent on E-selectin ligand, β1 integrin, and Rac1. Moreover, eliminating E-selectin ligand-synthesizing α1,3 fucosyltransferases in transgenic adenoma of mouse prostate mice dramatically reduced prostate cancer incidence. These results unify the requirement for E-selectin ligands, α1,3 fucosyltransferases, β1 and αVβ3 integrins, and Rac/Rap1 GTPases in mediating prostate cancer cell homing and entry into bone and offer new insight into the role of α1,3 fucosylation in prostate cancer development.

  5. Single-dose fentanyl sublingual spray for breakthrough cancer pain

    2013-07-01

    Full Text Available Donald R Taylor Comprehensive Pain Care PC, Marietta, GA, USA Abstract: Breakthrough cancer pain (BTCP is defined as a transient exacerbation of pain that arises in patients with otherwise controlled persistent pain. BTCP typically has a rapid onset and relatively short duration, but it causes a significant amount of physical and psychological distress for patients. Several rapid-onset fentanyl formulations have been introduced in the USA to replace traditional oral opioids for the treatment of BTCP: a transmucosal lozenge, a sublingual orally disintegrating tablet, a buccal tablet, a buccal soluble film, a pectin nasal spray and, the newest formulation to enter the market, a sublingual spray. This article reviews the six rapid-onset formulations of fentanyl approved in the USA for the management of BTCP with emphasis on describing the published literature on fentanyl sublingual spray. The different fentanyl formulations vary in pharmacokinetic properties and ease of use, but all have a rapid onset and a relatively short duration of analgesia. Fentanyl sublingual spray has demonstrated absorption within 5 minutes of administration, with fentanyl plasma concentrations increasing over the first 30 minutes and remaining elevated for 60–90 minutes in pharmacokinetic studies in healthy subjects. Fentanyl sublingual spray shows linear dose proportionality, and changes in the temperature or acidity of the oral cavity do not alter its pharmacokinetic properties. In patients with BTCP, statistically significant pain relief is measurable at 5 minutes after administration of fentanyl sublingual spray, when compared with placebo, with significant pain relief lasting at least 60 minutes after administration. Adverse events are typical of opioid treatment and are considered mild to moderate in intensity. In summary, fentanyl sublingual spray provides rapid onset of analgesia and is a tolerable and effective treatment for BTCP. Keywords: breakthrough pain

The pathophysiology of bone metastasis is poorly understood and related complications is complex.Bone pain consequent to metastatic cancer continues to be a major therapeutic challenge for clinicians and its alleviation is crucial to improving the patient's quality of life. Targeted radionuclide therapy is an effective and cost efficient treatment for multi-site metastatic bone pain, its advantages may also include therapy for subclinical micro-or oligometastatic disease before clinical manifestation. But radionuclides remain underutilized in such treatments.

  7. Radionuclide conjugates of calcitonin for imaging bone disease and cancer

    Greenland, William Edward Peverell

    2002-07-01

    Salmon calcitonin (sCt) is a peptide with a higher affinity for human calcitonin receptors (hCtR) than human calcitonin. It has been used for treating osteoporosis, Paget's disease and bone pain. High levels of hCtRs are expressed on osteoclasts, bone metastases and primary breast and prostate cancers. The peptide was chosen for radiolabelling as a possible imaging agent. Direct labelling with {sup 99m}Tc via simultaneous reduction of the indigenous disulfide bond and {sup 99m}TcO{sub 4}{sup -} (VII) with the water soluble phenyl phosphine (TPPDS) was performed. The radiolabelled peptide was not suitable for use as a radiopharmaceutical due to the heterogeneity of the product as observed by reverse phase HPLC and due to poor binding to the human breast cancer cell line MCF7. The electospray MS suggested a {sup 99}Tc-TPPDS (III) core instead of the expected {sup 99}Tc=O (V) core. Normal sCt has 3 conjugatible primary amines leading to a mixture of 8 possible products. A sCt analogue (sCtA) with a single primary amine was produced and conjugated to the chelator TETA to produce a single conjugated species. The sCtA-TETA was labelled with cold Cu and characterised by electospray MS. The monodentate ligand Hynic was synthesised directly into the peptide using N-{alpha}-Fmoc-N-{epsilon}-(Hynic-Boc)-Lys a novel orthogonally protected amino acid. The peptide was labelled with {sup 99m}Tc with tricine coligands. The radiolabelled peptide produced a single peak as observed by reverse phase HPLC and bound to MCF7 cell in a specific manner. The electospray MS suggested that one of the tricine coligands is lost due to the heating effect and possibly replaced by an adjacent histidine acting as a ternary ligand. The sCtLys{sup 18}-Hynic{sup 99m}Tc(tricine){sub 2} labelled peptide is the lead radiolabelled peptide and could be used for a normal biodistribution animal study, followed by clinical evaluation in humans.

    Cancer recurrence at the site of tumor resection remains a major threat to patient survival despite modern cancer therapeutic advances. Osteosarcoma, in particular, is a very aggressive primary bone cancer that commonly recurs after surgical resection, radiation, and chemotherapeutic treatment. The objective of the present in vitro study was to develop a material that could decrease bone cancer cell recurrence while promoting healthy bone cell functions. Selenium is a natural part of our diet which has shown promise for reducing cancer cell functions, inhibiting bacteria, and promoting healthy cells functions, yet, it has not been widely explored for osteosarcoma applications. For this purpose, due to their increased surface area, selenium nanoparticles (SeNP) were precipitated on a very common orthopedic tissue engineering material, poly-l-lactic acid (or PLLA). Selenium-coated PLLA materials were shown to selectively decrease long-term osteosarcoma cell density while promoting healthy, noncancerous, osteoblast functions (for example, up to two times more alkaline phosphatase activity on selenium coated compared to osteoblasts grown on typical tissue culture plates), suggesting they should be further studied for replacing tumorous bone tissue with healthy bone tissue. Importantly, results of this study were achieved without the use of chemotherapeutics or pharmaceutical agents, which have negative side effects.

    Introduction: Based on the concept of bifunctional radiopharmaceuticals, we have previously developed {sup 186}Re-complex-conjugated bisphosphonate analogs for palliation of painful bone metastases and have demonstrated the utility of these compounds. By applying a similar concept, we hypothesized that a bone-specific directed {sup 90}Y-labeled radiopharmaceutical could be developed. Methods: In this study, 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) was chosen as the chelating site, and DOTA was conjugated with 4-amino-1-hydroxybutylidene-1,1-bisphosphonate. [{sup 90}Y]DOTA-complex-conjugated bisphosphonate ([{sup 90}Y]DOTA-HBP) was prepared by coordination with {sup 90}Y, and its biodistribution was studied in comparison to [{sup 90}Y]citrate. Results: In biodistribution experiments, [{sup 90}Y]DOTA-HBP and [{sup 90}Y]citrate rapidly accumulated and resided in the bone. Although [{sup 90}Y]citrate showed a higher level of accumulation in the bone than [{sup 90}Y]DOTA-HBP, the clearances of [{sup 90}Y]DOTA-HBP from the blood and from almost all soft tissues were much faster than those of [{sup 90}Y]citrate. As a result, the estimated absorbed dose ratios of soft tissues to osteogenic cells (target organ) of [{sup 90}Y]DOTA-HBP were lower than those of [{sup 90}Y]citrate. Conclusions: [{sup 90}Y]DOTA-HBP showed superior biodistribution characteristics as a bone-seeking agent and led to a decrease in the level of unnecessary radiation compared to [{sup 90}Y]citrate. Since the DOTA ligand forms a stable complex not only with {sup 90}Y but also with lutetium ({sup 177}Lu), indium ({sup 111}In), gallium ({sup 67/68}Ga), gadolinium (Gd) and so on, complexes of DOTA-conjugated bisphosphonate with various metals could be useful as agents for palliation of metastatic bone pain, bone scintigraphy and magnetic resonance imaging.

    Full Text Available We describe a 31-years-old female patient with severe pain in both knees who had been diagnosed as Behcet’s disease (BD for 12 years. She had had a history of complications due to BD including superior vena cava thrombosis, pulmonary thromboembolism, uveitis, and erythema nodosum and has reported the administration of corticosteroid therapy irregularly. After radiologic evaluation, she has been diagnosed with bone infarction of both left and right knee with the existance of lupus anticoagulants (LA positivity. Severe joint pain without the evidence of arthritis must alert the clinician to the possibility of bone necrosis of the extremity, although those may rarely occur bilateral in BD.

    The leading European and American professional societies recommend that bone scans (BS) should be performed in the staging of lung cancer only in those patients with bone pain. This prospective study investigated the sensitivity of conventional skeletal scintigraphy in detecting osseous metastases in patients with lung cancer and addressed the potential consequences of failure to use this method in the work-up of asymptomatic patients. Subsequent to initial diagnosis of non-small cell lung cancer, 100 patients were examined and questioned regarding skeletal complaints. Two specialists in internal medicine decided whether they would recommend a bone scan on the basis of the clinical evaluation. Skeletal scintigraphy was then performed blinded to the findings of history and physical examination. The combined results of magnetic resonance imaging (MRI) of the vertebral column, positron emission tomography (PET) of skeletal bone and the subsequent clinical course served as the gold standard for the identification of osseous metastases. Bone scintigraphy showed an 87% sensitivity in the detection of bone metastases. Failure to perform skeletal scintigraphy in asymptomatic patients reduced the sensitivity of the method, depending on the interpretation of the symptoms, to 19-39%. Without the findings of skeletal scintigraphy and the gold standard methods, 14-22% of patients would have undergone unnecessary surgery or neoadjuvant therapy. On this basis it is concluded that bone scans should not be omitted in asymptomatic patients. (orig.)

    PurposeTo retrospectively evaluate the effectiveness of computed tomography-guided percutaneous microwave ablation (MWA) and cementoplasty in patients with painful bone metastases at high risk of fracture.Materials and MethodsThirty-five patients with 37 metastatic bone lesions underwent computed tomography-guided MWA combined with cementoplasty (polymethylmethacrylate injection). Vertebrae, femur, and acetabulum were the intervention sites and the primary end point was pain relief. Pain severity was estimated by visual analog scale (VAS) before treatment; 1 week post-treatment; and 1, 6, and 12 months post-treatment. Functional outcome was assessed by improved patient walking ability. Radiological evaluation was performed at baseline and 3 and 12 months post-procedure.ResultsIn all patients, pain reduction occurred from the first week after treatment. The mean reduction in the VAS score was 84, 90, 90 % at week 1, month 1, and month 6, respectively. Improved walking ability occurred in 100 and 98 % of cases at the 1- and 6-month functional outcome evaluations, respectively. At the 1-year evaluation, 25 patients were alive, and 10 patients (28 %) had died because of widespread disease. The mean reduction in the VAS score and improvement in surviving patients’ walking ability were 90 and 100 %, respectively. No patients showed evidence of local tumor recurrence or progression and pathological fracture in the treated sites.ConclusionOur results suggest that MWA combined with osteoplasty is safe and effective when treating painful bone metastases at high risk of fracture. The number of surviving patients at the 1-year evaluation confirms the need for an effective and long-lasting treatment.

    2008-05-01

    There is a critical need to develop new and effective cancer therapies that target bone, the primary metastatic site for prostate cancer and other malignancies. Among the various therapeutic approaches being considered for this application, gene-modified cell-based therapies may have specific advantages. Gene-modified cell therapy uses gene transfer and cell-based technologies in a complementary fashion to chaperone appropriate gene expression cassettes to active sites of tumor growth. In this paper, we briefly review potential cell vehicles for this approach and discuss relevant gene therapy strategies for prostate cancer. We further discuss selected studies that led to the conceptual development and preclinical testing of IL-12 gene-modified bone marrow cell therapy for prostate cancer. Finally, we discuss future directions in the development of gene-modified cell therapy for metastatic prostate cancer, including the need to identify and test novel therapeutic genes such as GLIPR1.

    Methadone is commonly used in the treatment of heroin addiction. Patients with a history of opioid misuse or on methadone maintenance therapy (MMT) with cancer often have difficult to manage pain. We studied 12 patients referred to the palliative care service with cancer pain who were on MMT. All had difficult to control pain, and a third required 5 or more analgesic agents. Two patients had documented \\'\\'drug-seeking\\'\\' behavior. Methadone was used subcutaneously as an analgesic agent in 1 patient. We explore why patients on MMT have difficult to manage pain, the optimal management of their pain, and the increasing role of methadone as an analgesic agent in cancer pain.

    Systemic use of radiopharmaceuticals is a recognized alternative method for the treatment of pain in patients with multiple bone metastasis. A new option, {sup 188}Re-HEDP is proposed, using generator-obtained {sup 188}Rhenium ({beta} energy = 2.1 MeV, {gamma} energy = 155 keV, half-life = 16.9 hours). After establishing parameters of biodistribution, dosimetry and image acquisition in mice, rats and rabbits, Phase I and II studies were conducted on 12 patients with multiple metastasis from carcinomas, with pain surpassing other analgesic options. More than 50% pain relief was found in 91% of the patients, with total relief during a variable period in 41% of them allowing opiate and other analgesic drugs to be decreased or withdrawn, and showing a lower bone marrow contribution to total absorbed dose than that reported for other similar radiopharmaceuticals. Further study of this option is recommended in order to determine higher dose protocols without toxic bone marrow reaction possibilities.

    For relief from cancer pain, we developed critical pathway (CP) as an effective strategy for the medical staff treating cancer patients. This CP was made out of Microsoft Excel, and was used on personal computers. "Good sleeping" was set as the first goal and the second was "No pain in rest position." To achieve this, physicians and nurses evaluate medical efficacy and complications including nausea/vomiting, constipation, somnolence and hallucination everyday using controlled release oxycodone in addition to NSAIDs and prochlorperazine, stool softener and peristaltic stimulant for adverse effects. These outcomes lead to the medication change the next day by calculation using visual basic function due to opioid titration theory. In twelve patients this CP was acceptable, and all of them achieved the second goal within a week without severe adverse effects except constipation.

    Full Text Available Objective. To investigate cancer pain management and evaluate factors that could be addressed and lead to potential improvement of pain therapy. Materials and methods. Two hundred patients with metastatic cancer pain at the Department of Oncology, University Hospital Mostar, completed questionnaires about cancer pain treatment. Thirty oncologists from the Cancer Institute, University of Sarajevo and the Department of Oncology, Clinical Hospital, Mostar were asked to complete the questionnaire about cancer pain management. Results. Compliance for analgesics was statistically better (p=0.013 for patients who were regularly asked about pain than for those patients who were asked periodically. Nearly twice as many patients, whom the doctor always asked about pain, regularly took medication (65.5% versus 32.8%. There was a statistically significant, positive relationship between regular use of analgesics and the interest of the doctor about pain reduction after initiation of analgesic therapy (p=0.008. Almost half of the patients, 47%, stated that their doctor did not devote enough time to their pain problems during the interview. Statistically significantly more patients took analgesic medication regularly if they were not afraid of narcotics (p=0.006. Numerical or VAS scales in description of cancer pain were used by only 30% of interviewed oncologists. The vast majority of doctors, 86.7%, used opiates for the terminal phase of the illness. Conclusion. Assessment and the treatment of cancer pain in Bosnia and Herzegovina remains inadequate, emphasizing the need for changes to cancer pain patient care.

    Full Text Available In the metastatic patterns of the cancer, the tumor foci are located more frequently in the tubular bones and vertebral column, just less frequently in the bones of the pelvis, and even more rarely in those of the shoulder and skull. Bone pain is usually related to the involvement of the periosteum that has an extensive network of nociceptors. Auxiliary exposures that directly affect the intensity of pain syndrome and the strength of bone structures are used in addition to basic therapy options for cancer of the prostate. Among these agents there are bisphosphonates. Once ingested, bisphosphonates are transported by blood to the areas of active bone tissue rearrangement where they are tightly bound to the mineral matrix. Their administration causes a considerable reduction in pain syndrome, a decrease in the frequency of complications of bone metastases, and an increase in time before a first bone complication. Antiresorptive therapy including particularly zoledronic acid (resorba or denosumab is a necessary treatment option in the above category of patients with bone metastases.

    Lutetium-177 is an emerging radionuclide due its convenient chemical and nuclear properties. In this paper we describe the development and evaluation in Uruguay of the targeted 177Lu labelled radiopharmaceuticals EDTMP (for bone pain palliation) and DOTA-TATE (neuroendocrine tumors). We optimized the preparation of these 177Lu radiopharmaceuticals including radiolabelling, quality control methods, in vitro and in vivo stability and their therapeutic application in patients. Radiation dosimetry aspects of 177Lu are also included. Nine male patients with prostate cancer and four female patients with breast carcinoma with multiple bone metastatic lesions were treated with 177Lu-EDTMP. Four patients with gastroentheropancreatic neuroendocrine tumors (GEP-NET) and one patient with bronchial NET were treated with 1- 3 cycles with a cumulative dose of 4.44-22.2 GBq of 177Lu-DOTA-TATE. Scintigraphic images of the patients treated with 177Lu-EDTMP evidenced high and rapid uptake in bone metastasis, remaining after 7 days post administration. Images allow skeletal visualization with high definition and demonstrate increased uptake in bone metastases. For 177Lu-DOTA-TATE, partial remissions were obtained in 4 patients and the remaining patient did not show significant progression 3 months after the second cycle. No serious adverse effects were registered, even in two patients with confirmed renal disease and high risk for renal disease Dosimetry assessments confirm the predictive value of the personalized therapy with radiolabelled peptides. We found it is possible to accumulate high therapeutic doses in tumours in sequential administrations of 177Lu-DOTA-TATE, increasing the probability of biological response without significant impairment of the renal function in patients with risk factors. These results demonstrate the attractive therapeutic properties of these two 177Lu labelled agents and the feasibility of this metabolic therapy in regions far away from 177Lu producing

    Full Text Available Background: Pain is a common primary symptom of advanced cancer and metastatic disease, occurring in 50-75% of all patients. Although palliative care and pain management are essential components in oncology practice, studies show that these areas are often inadequately addressed. Materials and Methods: We randomly selected 152 patients receiving palliative radiotherapy (PRT from October 2006 to August 2008, excluding metastatic bone lesions. Patients′ records were studied retrospectively. Results: A median follow-up of 21 weeks was available for 119 males and 33 females with a median age of 55 years. Maximum (60% patients were of head and neck cancers followed by esophagus (14%, lung (10% and others. Dysphagia, growth/ulcer and pain were the chief indications for PRT. Pain was present in 93 (61% cases out of which, 56 (60% were referred to pain clinic. All except one consulted pain clinic with a median pain score of 8 (0-10 point scale. Fifty-three of these 56 patients (96% received opioid-based treatment with adequate pain relief in 33% cases and loss of follow-up in 40% cases. Only five (3% cases were referred to a hospice. Twenty-two (14% cases were considered for radical treatment following excellent response to PRT. Conclusion: In this selective sample, the standard of analgesic treatment was found to be satisfactory. However, there is a lot of scope for improvement regarding referral to pain clinic and later to the hospice. Patients′ follow-up needs to be improved along with future studies evaluating those patients who were considered for further RT till radical dose. Programs to change the patients′ attitude towards palliative care, physicians′ (residents′ training to improve communication skills, and institutional policies may be promising strategies.

    Full Text Available BACKGROUND AND OBJECTIVES: the medications used according to the recommendation of the World Health Organization do not promote pain relief in a number of patients with cancer pain. The aim of this study was to evaluate the use of morphine as first medication for the treatment of moderate cancer pain in patients with advanced and/or metastatic disease, as an option to the recommendations of the World Health Organization analgesic ladder. METHOD: sixty patients without opioid therapy, with >18 years of age, were randomized into two groups. G1 patients received medication according to the analgesic ladder and started treatment with non-opioids in the first, weak opioids in the second, and strong opioids in the third step; G2 patients received morphine as first analgesic medication. The efficacy and tolerability of initial use of morphine were evaluated every two weeks for three months. RESULTS: the groups were similar with respect to demographic data. There was no significant difference between the groups regarding pain intensity, quality of life, physical capacity, satisfaction with treatment, need for complementation and dose of morphine. In G1 there was a higher incidence of nausea (p = 0.0088, drowsiness (p = 0.0005, constipation (p = 0.0071 and dizziness (p = 0.0376 in the second visit and drowsiness (p = 0.05 in the third. CONCLUSIONS: the use of morphine as first medication for pain treatment did not promote better analgesic effect than the ladder recommended by World Health Organization, with higher incidence of adverse effects.

    Full Text Available Abstract It has been reported that remarkable and sustained activation of astrocytes and/or microglia occurs in cancer induced pain (CIP, which is different from neuropathic and inflammatory pain. The present study was designed to investigate the role of spinal Toll-like receptor 4 (TLR4 induced glial neuroinflammation in cancer induced pain using a modified rat model of bone cancer. The rat model of CIP consisted of unilateral intra-tibial injection with Walker 256 mammary gland carcinoma. Nine days after Walker 256 inoculation, a robust activation of both astrocytes and microglia in bilateral spinal dorsal horn was observed together with significant bilateral mechanical allodynia. This neuroinflammation was characterized by enhanced immunostaining of both glial fibrillary acidic protein (GFAP, astrocyte marker and OX-42 (microglia marker, and an elevated level of IL-1β, IL-6 and TNF-α mRNA. I.t. administration of fluorocitrate (an inhibitor of glial metabolism, 1 nmol or minocycline (an inhibitor of microglia, 100 μg has significant anti-allodynic effects on day 12 after Walker 256 inoculation. Naloxone (a nonstereoselective TLR4 signaling blocker, 60 μg, i.t. also significantly alleviated mechanical allodynia and simultaneously blocked the increased inflammatory cytokine mRNA. The results suggested that spinal TLR4 might play an important role in the sustained glial activation that critically contributed to the robust and sustained spinal neuroinflammation in CIP. This result could potentially help clinicians and researchers to better understand the mechanism of complicated cancer pain.

Then, we examine in more detail the emerging evidence for the potential impact of analgesic use on cancer risk and disease progression. Increasing findings suggest that long-term use of nonsteroidal anti-inflammatory drugs, particularly aspirin, may reduce cancer occurrence. However, acetaminophen may raise the risk of some hematological malignancies. Drugs acting upon receptors of gamma-aminobutyric acid (GABA and GABA “mimetics” (eg, gabapentin appear generally safe for cancer patients, but there is some evidence of potential carcinogenicity. Some barbiturates appear to slightly raise cancer risks and can affect cancer cell behavior in vitro. For cannabis, studies suggest an increased risk of squamous cell carcinoma of the tongue, larynx, and possibly lung. Morphine may stimulate human microvascular endothelial cell proliferation and angiogenesis; it is not clear whether this might cause harm or produce benefit. The opioid, fentanyl, may promote growth in some tumor cell lines. Opium itself is an emerging risk factor for gastric adenocarcinoma and possibly cancers of the esophagus, bladder, larynx, and lung. It is concluded that analgesics currently prescribed for cancer pain can

    Primary angiosarcoma of the bone (PAB) is a rare and fatal high-grade malignant vascular bone tumor. We report a rare case of multicentric PAB mimicking bone metastasis in a 59-year-old female patient with a history of sigmoid colon cancer. This patient complained of lower back and pelvic pain and presented with multiple osteolytic bone lesions on plain radiography and pelvic computed tomography. First, bone metastasis of sigmoid colon cancer was suspected. However, on the {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) scan, the patient presented unusual multiple hypermetabolic osteolytic bone lesions involving contiguous bones of the lower half of the body. After bone biopsy, these lesions were confirmed to be multicentric PAB. To the best of our knowledge, this is the first case report of an {sup 18}F-FDG PET/CT scan in a patient with multicentric primary bone angiosarcoma.

    Our objective in this study was to review the experience of a one-stop multidisciplinary bone metastases clinic (BMC) that offers a coordinated multidisciplinary approach to the care of cancer patients with bone metastases in a tertiary cancer centre. Patients with symptomatic bone metastases were referred to BMC and assessed by a team of specialists in various disciplines - interventional radiology, orthopedic surgery, palliative medicine, and radiation oncology. At initial consultation, patient demographics, reasons for referral, and case disposition were recorded. From January 1999 to February 2005, a total of 272 patients with bone metastases were referred to the BMC. The median age was 65 years (range 28-95) and median KPS score at consultation was 60 (range 30-90). The majority of patients came from home (74%), while others came from a nursing home or the hospital (9%). Almost a third (28%) of patients had 2 or more reasons of referral, yielding a total of 354 reasons. The most common reason for referral was bone pain (42%), bone metastases (21%), high risk for pathological fracture (12%), and pathological fracture (10%). Of the 272 patients who received consultation, 40% received palliative radiotherapy, 19% received interventional surgery, 7% were referred to other support services such as palliative care, physiotherapy, and 7% had further investigation or imaging. A multidisciplinary clinic is useful for co-coordinating the management of bone metastatic disease in symptomatic patients.

    Full Text Available Quality of life (QoL encompasses the physical, psychosocial, social and spiritual dimensions of life lived by a person. Cancer pain is one of the physical component has tremendous impact on the QoL of the patient. Cancer pain is multifaceted and complex to understand and managing cancer pain involves a tool box full of pharmacological and non pharmacological interventions but still there are 50-70% of cancer patients who suffer from uncontrolled pain and they fear pain more than death. Aggressive surgeries, radiotherapy and chemotherapy focus more on prolonging the survival of the patient failing to realize that the QoL lived also matters equally. This paper reviews complementary and alternative therapy approaches for cancer pain and its impact in improving the QoL of cancer patients.

    Metabolic radiotherapy offers an alternative therapeutic tactic in patients with painful bone metastases. The efficacy and toxicity of Quadramet were evaluated in 77 patients. All patients received a 37 MBq/kg dose of Quadramet, and 13 patients received the dose twice. Then, the efficacy of treatment was evaluated according to WHO/OMS score, to pain relief and modification of opioid treatment. The WHO/OMS score was not changed or increased in 87.5 % (63172) of patients. The pain relief was observed in 77.8 % (56/72) of patients. The antalgic treatment decreased in 76.4 % (55/72) of patients. In patients with prostatic cancer, pain relief (79.2 % of patients) was more noticeable than in patients with breast cancer (76.9 % of patients). An opposite response was observed in 8.3 % (6/72) of patients. The rate of PSA decreased in 42.8 % (12/28) of patients with prostatic cancer. The only toxicity observed was myelo-toxicity. This toxicity was moderate and recovered by 8 weeks. After the second administration of Quadramet as well as after the first, we observed the pain relief in 76.9 % of patients. The results of our study confirm the efficacy and the safety of Quadramet in early painful bone metastases treatment. This treatment can be repeated without decrease of the efficacy. (authors)

    Bone/joint pain and difficulty with sexual arousal are prevalent, frequently severe, and potentially treatable in patients on maintenance hemodialysis. However, the mediators and adequacy of treatment for these symptoms have been less well studied. We sought to assess the clinical correlates and treatment of these symptoms in patients receiving chronic hemodialysis. Using the Dialysis Symptom Index, we assessed the presence and severity of bone/joint pain and difficulty with sexual arousal in 75 patients on chronic hemodialysis. Associations of demographic and clinical variables with these 2 symptoms were assessed. We also recorded the use of analgesics for bone/joint pain and, among men, phosphodiesterase-5 inhibitors for difficulty with sexual arousal. Twenty-eight patients (37%) reported bone/joint pain, of whom 20 (71%) described it as moderate to severe. Nineteen of 50 male patients (38%) reported difficulty with sexual arousal, which was described as moderate to severe by 15 (79%). Patients' demographic and clinical characteristics were not correlated with bone/joint pain. Among men, there were no correlations between patients' demographic and clinical characteristics and difficulty with sexual arousal. Only 48% of patients with bone/joint pain were receiving analgesics, while 21% of men who described difficulty with sexual arousal were receiving phosphodiesterase-5 inhibitors. Demographic, clinical, and dialysis-related variables are poorly correlated with bone/joint pain and difficulty with sexual arousal. However, these symptoms are prevalent and under-treated, which should spur efforts to assess the impact of improving provider assessment and treatment of these symptoms on patient outcomes, including health-related quality of life.

    The surgical outcome of most early gastric cancer (EGC)is usually satisfactory. Some cases show bone metastasis even though the depth of cancer invasion is confined to the mucosa. The most frequent site for recurrence of EGC is the liver. Cases of EGC with bone metastasis are reviewed to clarify the clinicopathological characteristics of EGC giving rise to bone metastasis. Possible mechanisms and risk factors underlying this rare condition are proposed.Forty-six cases of bone metastasis from EGC are reviewed from published reports and meeting proceedings in Japan.This investigation suggests that risk factors for bone metastasis from EGC include depressed-type signet-ring cell carcinoma, poorly differentiated carcinoma, and/or the likely involvement of lymph node metastasis, even though the cancer is confined to the gastric mucosa. The risk factors do not include recurrence of EGC in the liver. We speculate that the mechanism of bone metastasis from EGC is via lymphatic channels and systemic circulation. Postoperative follow-up of cases should consider the development of bone metastasis from EGC. We propose the use of elevated alkaline phosphatase levels for the detection of bone metastasis and recommend bone scintigraphy in positive cases.

    To evaluate the effectiveness and safety of fentanyl-TTS in the management of radiotherapy induced acute pain and cancer pain treated with radiotherapy. Our study was open labelled prospective phase IV multi-center study, the study population included patients with more 4 numeric rating scale (NRS) score pain although managed with other analgesics or more than 6 NRS score pain without analgesics. Patients divided into two groups: patients with radiotherapy induced pain (Group A) and patients with cancer pain treated with radiotherapy (Group B). All patients received 25 ug/hr of fentanyl transdermal patch. Primary end point was pain relief: second end points were change in patient quality of life, a degree of satisfaction for patients and clinician, side effects. Between March 2005 and June 2005, 312 patients from 26 participating institutes were registered, but 249 patients completed this study. Total number of patients in each group was 185 in Group A, 64 in Group B. Mean age was 60 years and male to female ratio was 76:24. Severe pain NRS score at 2 weeks after the application of fentanyl was decreased from 7.03 to 4.01, {rho} = 0.003. There was a significant improvement in insomnia, social functioning, and quality of life. A degree of satisfaction for patients and clinician was very high. The most common reasons of patients' satisfactions was good pain control. Ninety six patients reported side effect. Nausea was the most common side effect. There was no serious side effect. Fentanyl-TTS was effective in both relieving pain with good tolerability and improving the quality of life for patients with radiotherapy induced acute pain and cancer pain treated with radiotherapy. The satisfaction of the patients and doctors was good. There wa no major side effect.

    The Dutch clinical practice guideline on the diagnosis and management of pain in patients with cancer was published in 2008 and intensively promoted to healthcare professionals who see patients with cancer. One of the most important recommendations is the systematic registering of the pain and its intensity. To evaluate in which degree this part of the practice guideline is implemented, we analyzed the medical records of patients attending the outpatient oncological clinic in an academic hospital, a large teaching hospital, and 4 smaller peripheral hospitals. None of the participating hospitals assessed pain by a standardized scale. Reference to pain in the medical record happened more frequently in the academic hospital than in the other hospitals. The frequency of recording pain in the medical record in the academic hospital was much higher in this study than the one previously reported, whereas the findings in the other hospitals were comparable. There may be several reasons for the difference in reporting rate of pain in patients with cancer. Our findings indicate that the clinical practice guideline with regard to pain registration is poorly implemented in oncology outpatient clinics. More efforts should be made to generate the awareness for the need of pain registration.

    Twenty-six adult patients more than 6-months post-lumbar spinal fusion were studied. Flexion and extension radiographs showing motion or bone scintigrams, showing focal areas of increased activity within the fusion mass were considered positive for pseudarthrosis. Patients were classified as either symptomatic or asymptomatic. Among the 15 symptomatic patients, scintigraphy had a sensitivity of 0.78 and a specificity of 0.83 which was superior to the 0.43 sensitivity and 0.50 specificity of radiography. Six of the 11 asymptomatic patients had focal areas of increased activity in the bony fusion mass, possibly reflecting painless pseudarthrosis. Planar imaging was substantially enhanced by SPECT in 14 of the 26 cases. It is concluded that for the patient who remains symptomatic after lumbar spinal fusion, bone scintigraphy with SPECT is of significant value in detecting painful pseudarthrosis.

  16. Single-dose fentanyl sublingual spray for breakthrough cancer pain.

    Taylor, Donald R

    2013-01-01

    Breakthrough cancer pain (BTCP) is defined as a transient exacerbation of pain that arises in patients with otherwise controlled persistent pain. BTCP typically has a rapid onset and relatively short duration, but it causes a significant amount of physical and psychological distress for patients. Several rapid-onset fentanyl formulations have been introduced in the USA to replace traditional oral opioids for the treatment of BTCP: a transmucosal lozenge, a sublingual orally disintegrating tablet, a buccal tablet, a buccal soluble film, a pectin nasal spray and, the newest formulation to enter the market, a sublingual spray. This article reviews the six rapid-onset formulations of fentanyl approved in the USA for the management of BTCP with emphasis on describing the published literature on fentanyl sublingual spray. The different fentanyl formulations vary in pharmacokinetic properties and ease of use, but all have a rapid onset and a relatively short duration of analgesia. Fentanyl sublingual spray has demonstrated absorption within 5 minutes of administration, with fentanyl plasma concentrations increasing over the first 30 minutes and remaining elevated for 60-90 minutes in pharmacokinetic studies in healthy subjects. Fentanyl sublingual spray shows linear dose proportionality, and changes in the temperature or acidity of the oral cavity do not alter its pharmacokinetic properties. In patients with BTCP, statistically significant pain relief is measurable at 5 minutes after administration of fentanyl sublingual spray, when compared with placebo, with significant pain relief lasting at least 60 minutes after administration. Adverse events are typical of opioid treatment and are considered mild to moderate in intensity. In summary, fentanyl sublingual spray provides rapid onset of analgesia and is a tolerable and effective treatment for BTCP.

  17. Innate Immune Signalling Genetics of Pain, Cognitive Dysfunction and Sickness Symptoms in Cancer Pain Patients Treated with Transdermal Fentanyl.

    Full Text Available Common adverse symptoms of cancer and chemotherapy are a major health burden; chief among these is pain, with opioids including transdermal fentanyl the mainstay of treatment. Innate immune activation has been implicated generally in pain, opioid analgesia, cognitive dysfunction, and sickness type symptoms reported by cancer patients. We aimed to determine if genetic polymorphisms in neuroimmune activation pathways alter the serum fentanyl concentration-response relationships for pain control, cognitive dysfunction, and other adverse symptoms, in cancer pain patients. Cancer pain patients (468 receiving transdermal fentanyl were genotyped for 31 single nucleotide polymorphisms in 19 genes: CASP1, BDNF, CRP, LY96, IL6, IL1B, TGFB1, TNF, IL10, IL2, TLR2, TLR4, MYD88, IL6R, OPRM1, ARRB2, COMT, STAT6 and ABCB1. Lasso and backward stepwise generalised linear regression were used to identify non-genetic and genetic predictors, respectively, of pain control (average Brief Pain Inventory < 4, cognitive dysfunction (Mini-Mental State Examination ≤ 23, sickness response and opioid adverse event complaint. Serum fentanyl concentrations did not predict between-patient variability in these outcomes, nor did genetic factors predict pain control, sickness response or opioid adverse event complaint. Carriers of the MYD88 rs6853 variant were half as likely to have cognitive dysfunction (11/111 than wild-type patients (69/325, with a relative risk of 0.45 (95% CI: 0.27 to 0.76 when accounting for major non-genetic predictors (age, Karnofsky functional score. This supports the involvement of innate immune signalling in cognitive dysfunction, and identifies MyD88 signalling pathways as a potential focus for predicting and reducing the burden of cognitive dysfunction in cancer pain patients.

    Full Text Available One in four breast cancer patients is at risk of developing bone metastases in her life time. The early prevention of bone metastases is a crucial challenge. It has been suggested that the use of zoledronic acid (ZOL in the adjuvant setting may reduce the persistence of disseminated tumor cells and thereby might improve outcome, specifically in a population of patients with a low estrogen microenvironment. More recently, the results of a large meta-analysis from 41 randomized trials comparing a bisphosphonate (BP to placebo or to an open control have been presented at the 2013 San Antonio Breast Cancer Meeting. Data on 17,016 patients confirm that adjuvant BPs, irrespective of the type of treatment or the treatment schedule and formulation (oral or intra-venously (IV, significantly reduced bone recurrences and improved breast cancer survival in postmenopausal women. No advantage was seen in premenopausal women. BPs are soon likely to become integrated into standard practice. Published data on the mechanisms involved in tumor cell seeding from the primary site, in homing to bone tissues and in the reactivation of dormant tumor cells will be reviewed; these might offer new ideas for innovative combination strategies.

    Cancer pain consists of continuous pain lasting almost all day and transient exacerbation of pain called breakthrough pain. Breakthrough pain is classified as somatic pain and visceral pain, neuropathic pain according to the character of pain. Although the immediate release opioid is used as the first treatment of choice to breakthrough pain, the effect is not enough when it shows the character of neuropathic pain. Pregabalin has become the first medicine for the treatment of neuropathic pain, and it sometimes reveals prompt analgesic effect based on its pharmacological profile. It has also been reported that pregabalin used with oxycodine reveals analgesic effect with smaller dosage than pregabalin alone. We experienced a young patient with lung cancer suffering from sudden exacerbation of symptomatic sciatica, whose pain was markedly reduced within 30 minutes by taking immediate release oxycodone 5 mg and pregabalin 75 mg simultaneously. Conclusions : Pregabalin with immediate release oxycodone simultaneously may be able to improve acute exacerbation of neuropathic cancer pain rapidly.

    Breast cancer often metastasizes to bone causing osteolytic bone resorption which releases active TGFβ. Because TGFβ favors progression of breast cancer metastasis to bone, we hypothesized that treatment using anti-TGFβ antibody may reduce tumor burden and rescue tumor-associated bone loss in metastatic breast cancer. In this study we have tested the efficacy of an anti-TGFβ antibody 1D11 preventing breast cancer bone metastasis. We have used two preclinical breast cancer bone metastasis models, in which either human breast cancer cells or murine mammary tumor cells were injected in host mice via left cardiac ventricle. Using several in vivo, in vitro and ex vivo assays, we have demonstrated that anti-TGFβ antibody treatment have significantly reduced tumor burden in the bone along with a statistically significant threefold reduction in osteolytic lesion number and tenfold reduction in osteolytic lesion area. A decrease in osteoclast numbers (p = 0.027) in vivo and osteoclastogenesis ex vivo were also observed. Most importantly, in tumor-bearing mice, anti-TGFβ treatment resulted in a twofold increase in bone volume (ptreatment with anti-TGFβ antibody increased the mineral-to-collagen ratio in vivo, a reflection of improved tissue level properties. Moreover, anti-TGFβ antibody directly increased mineralized matrix formation in calverial osteoblast (p = 0.005), suggesting a direct beneficial role of anti-TGFβ antibody treatment on osteoblasts. Data presented here demonstrate that anti-TGFβ treatment may offer a novel therapeutic option for tumor-induced bone disease and has the dual potential for simultaneously decreasing tumor burden and rescue bone loss in breast cancer to bone metastases. This approach of intervention has the potential to reduce skeletal related events (SREs) in breast cancer survivors.

The knowledge of cancer pain management may be a hindrance to the proper assessment and treatment of pain in cancer patients.Objective: This report presents an evaluation of the knowledge and practice of cancer pain management among medical practitioners in Ahmadu Bello University Teaching Hospital Shika, Zaria.Methods: This report involves medical practitioners at the Ahmadu Bello University Teaching Hospital who are directly involved in the management of cancer patients. Information was obtained using a structured questionnaire, and the data were analyzed using SPSS (version 11.5.Results: The response rate to the questionnaire was 82%, with an age range of 23 to 50 years (mean age, 34.9, and the majority of actual respondents, 55 (67%, were male. Thirty-six (44% strongly agreed that cancer patients require pain relief. Yet only 40% of the respondents routinely conducted pain assessments among cancer patients, while 51% only treated when patients complained of pain. Concerning the type of analgesic commonly used for cancer patients, 43% used weak opioids, 32% used NSAIDs, and only 20% used strong opioids. Seventy-five respondents (91.5% had no formal training on pain management.Conclusion: The knowledge of pain management for cancer patients among medical personnel at the Ahmadu Bello University Teaching Hospital appears to be elementary. We recommend that formal training in the form of lectures, seminars, and workshops on cancer pain management should be part of continuing medical education in low-resource settings like the Ahmadu Bello University Teaching Hospital.Keywords: cancer pain, management, evaluation

    Transplants from the anterior iliac crest are used for most reconstructive procedures in cranio-maxillofacial surgery. The advantages are easy accessibility, the ability to work in two teams and the amount of corticocancellous bone available; disadvantages are postoperative pain and gait disturbances. To reduce donor-site pain, the effect of a single dose of bupivacaine (10 cc of 2.5mg/cc with 1:80.000 epinephrine) was studied. 200 consecutive patients, who underwent anterior iliac crest bone harvesting for reconstructive procedures, were randomly divided into those receiving bupivacaine and those not. They completed a standardized questionnaire. Patients scored the intensity of the pain and difficulties walking at different times with a visual analogue scale. They recorded analgesics used. 98 questionnaires were eligible for analysis. No differences between the bupivacaine and the control group were detected for postoperative pain and gait disturbance. There is no support for administration of a single dose of bupivacaine to reduce pain in the first postoperative days. The surface area of the removed bone had a significant influence on pain and walking; pain is related to the local osseous damage or periosteal stripping rather than to the length of incision or the operation time.

    The records of 1018 patients with low back pain in a tertiary spine referral practice were reviewed. One hundred thirty-nine out of 1018 (13.6%) underwent technetium-99m planar bone scannings as part of their investigation. Seventy-three out of 139 scans (52%) showed increased uptake in some area, but only 27 out of 139 (19.4%) showed increased uptake specifically in the low back. Scans consistently yielded no findings with reference to the back when the prescan diagnosis was spinal stenosis, lumbar pain syndrome, herniated nucleus pulposus, or postlaminectomy syndrome. Some scans gave positive findings in patients with a diagnosis of degenerative disc disease, pseudoarthrosis, spondylolisthesis, fracture, infection, metabolic disorder, or tumor. Positive scans were generally obtained early after presentation (within 3 months) and negative scans obtained later (after 6 months), suggesting that clinical suspicion is still the main indication for early scanning. Planar bone scanning was helpful in both diagnosis and therapeutic decision-making in many conditions. (orig.)

    In this study we aimed to determine the role of bone scintigraphy as an objective diagnostic method in patients with heel pain. Sixty-seven heels of 50 of 182 patients with defined features who attended the orthopedics outpatient clinic with heel pain over a 3-year period, were treated with combined methods such as nonsteroidal anti-inflammatory drugs (NSAID) and contrast baths, stretching exercises and changing of footwear habits. A one year follow-up was established. The criteria identified by Wolgin et al. were used in assessing the results of the treatment. Subcalcaneal spur was demonstrated by radiography in 44 of the 67 heels. There were two different imaging patterns observed on three phase bone scintigraphy. Type I imaging pattern: Focal increased activity in the heel region or normal activity on dynamic and the blood pool phases and focal increased activity at the inferior calcaneal surface in the late static phase. Type II imaging pattern: Diffuse increased activity along the plantar fascia in the dynamic and the blood pool phase, and focal increased activity at the inferior calcaneal surface in the late static phase. There were 34 (50.7%) type I and 18 (26.8%) type II imaging patterns on the scans. Type I and type II imaging patterns were described as osseous and fascial respectively. At the final examination, the results for pattern type I were good in 16 patients (66.7%), fair in 6 patients (25%) and poor in 2 patients (8.3%), whereas in pattern type II results were good in 12 patients (80%) and fair in 3 patients (20%). The recurrence frequency was 4.1% and 6.6%, respectively. Subcalcaneal spur was determined in 70.5% of the patients with osseous pathology and 55.5% of the patients with fascial pathology. Based on this result, it can be ascertained that calcaneal spurs develop during the pathological process causing heel pain. Other findings supporting this claim were the differences in symptom periods of the patients with type I and type II imaging

    2007-01-01

    Objective: To investigate the proper conversing rate from morphine to continuous infusion of fentanyl in patients suffering cancer pain. Methods: A retrospective study was carried on in 20 patients with cancer pain in Shizuoka Cancer Center from Sep. 2002 to Nov. 2003. Pain intensity, adverse reactions, and satisfaction index of patients were evaluated. Results: The pain intensity was stable in 17 patients indicating good pain-control within 1 week after conversion and unstable in 3 patients after conversion suggesting poor pain-control. Fentanyl injection could alleviate side effects and increase the satisfaction index of patients. Conclusion: The equipotent ratio for ratio less than 72:1 was proposed to get stable pain-relieving effect. But the equipotent ratio for conversion of morphine to continuous infusion of fentanyl could not be determined. We must consider the morphine dose before the confirmation of the conversing rate.

    Terminal cancer patients report substantial pain frequently. Pain control can be achieved in many patients with conventional methods and analgesics. However, significant numbers of patients remain in pain. For these patients, continuous intrathecal narcotics delivered by an external portable pump via a subcutaneous port, offer substantially improved pain control with minimal risk of serious systemic complications. Duration of treatment in our 40 cancer patients lasted up to 11 month. Continuous intrathecal morphine or fentanyl relieved pain till death due to cancer. Supraspinal side effects of opioids were only seen during the first week of intrathecal narcotic treatment. No serious complications like meningitis or other infections were observed. Postmortem examination also could not detect changes of the cord or signs of arachnoiditis due to intrathecal narcotics or the implanted catheter. We conclude, that continuous intrathecal narcotic infusion by means of small portable pump is a very efficient method to control terminal cancer pain and enables treatment on an outpatient basis until death.

    Purpose: To investigate the relative importance of patient-reported hip and sacral pain after pelvic radiotherapy (RT) for gynecological cancer and its relationship to the absorbed doses in these organs. Methods and Materials: We used data from a population-based study that included 650 long-term gynecological cancer survivors treated with pelvic RT in the Gothenburg and Stockholm areas in Sweden with a median follow-up of 6 years (range, 2-15) and 344 population controls. Symptoms were assessed through a study-specific postal questionnaire. We also analyzed the hip and sacral dose-volume histogram data for 358 of the survivors. Results: Of the survivors, one in three reported having or having had hip pain after completing RT. Daily pain when walking was four times as common among the survivors compared to controls. Symptoms increased in frequency with a mean absorbed dose >37.5 Gy. Also, two in five survivors reported pain in the sacrum. Sacral pain also affected their walking ability and tended to increase with a mean absorbed dose >42.5 Gy. Conclusions: Long-term survivors of gynecological cancer treated with pelvic RT experience hip and sacral pain when walking. The mean absorbed dose was significantly related to hip pain and was borderline significantly related to sacral pain. Keeping the total mean absorbed hip dose below 37.5 Gy during treatment might lower the occurrence of long-lasting pain. In relation to the controls, the survivors had a lower occurrence of pain and pain-related symptoms from the hips and sacrum compared with what has previously been reported for the pubic bone.

    The aim of this retrospective study was to evaluate the efficacy and the safety of Quadramet and Metastron in 76 patients with painful bone metastases. The analgesic response was evaluated at six weeks, three months and six months. Blood counts performed every week allowed an assessment of the toxicity. The internal radiotherapy reduced the pain in 60% of patients with a complete pain disappearance in 26% and a reduction of analgesic consumption in 67% of them. This study did not show any statistically significant difference between the two treatments. However, we demonstrated that patients with a relatively long survival ({>=} 4 months) had a better analgesic response (73 against 29%, p = 0.0004). The patients with a less than four months survival and those with CIVD and liver metastasis had a higher risk of thrombopenia. This retrospective study suggests that these treatments should be given preferably to treat patients with a relatively tong life expectancy and that the detection of sub-clinic CIVD and liver metastasis could help to avoid severe thrombopenia.

    Background Bone scintigraphy is the standard procedure for the detection of bone metastases in breast cancer patients. FDG-PET/CT has been reported to be a sensitive tool for tumor staging in different malignant diseases. However, its accuracy for the detection of bone metastases has not been compared to bone scintigraphy. Purpose To compare whole-body FDG-PET/CT and bone scintigraphy for the detection of bone metastases on a lesion basis in breast cancer patients. Material and Methods Twenty-nine consecutive women (mean age 58 years, range 35-78 years) with histologically proven breast cancer were assessed with bone scintigraphy and whole-body FDG-PET/CT. Twenty-one patients (72%) were suffering from primary breast cancer and eight patients (28%) were in aftercare with a history of advanced breast cancer. Both imaging procedures were assessed for bone metastases by a radiologist and a nuclear medicine physician. Concordant readings between bone scintigraphy and FDG-PET/CT were taken as true. Discordant readings were verified with additional MRI imaging in all patients and follow-up studies in most patients. Results A total of 132 lesions were detected on bone scintigraphy, FDG-PET/CT or both. According to the reference standard, 70/132 lesions (53%) were bone metastases, 59/132 lesions (45%) were benign, and three lesions (2%) remained unclear. The sensitivity of bone scintigraphy was 76% (53/70) compared to 96% (67/70) for FDG-PET/CT. The specificity of bone scintigraphy and FDG-PET/CT was 95% (56/59) and 92% (54/59), respectively. According to the reference standard bone metastases were present in eight out of the 29 patients (28%), whereas 20 patients (69%) were free of bone metastases. One (3%) patient had inconclusive readings on both modalities as well as on MRI and follow-up studies. Bone scintigraphy and FDG-PET/CT correctly identified seven out of eight patients with bone metastases and 20 out of 20 patients free of metastases. Conclusion On a lesion

    Full Text Available Bone-seeking therapeutic radiopharmaceuticals are utilized on the basis of the radionuclide?s particulate emissions (primarily low to intermediate beta emission. The requirements therefore are different from those of bone imaging agents that consist mainly of short-lived single photon emitters. Lately, the therapeutic bone seeking radiopharmaceuticals have attained increasing importance due to their potential role in alleviating pain from osseous metastases in cancer patients, for the treatment of joint pain resulting from inflamed synovium (radiosynoviorthesis, or radiosynovectomy, or from various other forms of arthritic disease. There is, however, a paucity of published data on the bio-pharmacokinetics of these agents when used following intravenous administration for bone pain palliation. This paper will briefly review and summarize the presently available chemical and biopharmacokinetic information on the various clinically approved as well as experimental bone-localizing therapeutic radiopharmaceuticals, and make projections on their clinical application for the treatment of primary/metastatic cancer in bone.

    Pain is a common symptom in patients with head and neck cancer (HNC) that is associated with significant decrements in physical and psychological functioning. Only 4 studies have evaluated for changes in and predictors of different pain characteristics in these patients. In this longitudinal study of patients with HNC, changes in pain intensity (i.e., average pain, worst pain), pain interference with function, and pain relief were evaluated from the initiation of radiotherapy and through the following 6 months. Hierarchical linear modeling was used to evaluate for changes over time in these 4 pain characteristics, as well as to identify predictors of interindividual variability in each characteristic. Overall, pain intensity and interference with function scores were in the mild-to-moderate range, while pain relief scores were in the moderate range. The occurrence of pain, as well as scores for each pain characteristic, increased from the initiation to the completion of radiotherapy, followed by a gradual decrease to near pretreatment levels at 6 months. However, interindividual variability existed in patients' ratings of each pain characteristic. Predictors of more severe pain characteristic scores were more comorbidities, worse physical functioning, not having surgery before radiotherapy, difficulty swallowing, mouth sores, sleep disturbance, fatigue, more energy, and less social support. Patients with more depressive symptoms had better pain relief. Although some of the predictors cannot be modified (e.g., rrence of surgery), other predictors (e.g., symptoms) can be treated. Therefore, information about these predictors may result in decreased pain in patients with HNC.

    Bone metastasis is one of the most prevalent complications of late-stage breast cancer, in which the native bone matrix components, including osteoblasts, are intimately involved in tumor progression. The development of a successful in vitro model would greatly facilitate understanding the underlying mechanism of breast cancer bone invasion as well as provide a tool for effective discovery of novel therapeutic strategies. In the current study, we fabricated a series of in vitro bone matrices composed of a polyethylene glycol hydrogel and nanocrystalline hydroxyapatite of varying concentrations to mimic the native bone microenvironment for the investigation of breast cancer bone metastasis. A stereolithography-based three-dimensional (3D) printer was used to fabricate the bone matrices with precisely controlled architecture. The interaction between breast cancer cells and osteoblasts was investigated in the optimized bone matrix. Using a Transwell® system to separate the two cell lines, breast cancer cells inhibited osteoblast proliferation, while osteoblasts stimulated breast cancer cell growth, whereas, both cell lines increased IL-8 secretion. Breast cancer cells co-cultured with osteoblasts within the 3D bone matrix formed multi-cellular spheroids in comparison to two-dimensional monolayers. These findings validate the use of our 3D printed bone matrices as an in vitro metastasis model, and highlights their potential for investigating breast cancer bone metastasis.

    Early whole body bone scintigraphy was performed on 25 patients with prostatic cancer (15 cases with bone metastases and 10 cases without bone metastasis) to obtain anterior and posterior whole body images five minutes after administration of [sup 99m]Tc-hydroxymethylene diphosphonate(HMDP). The results were compared with the findings of routine bone scintigraphy after three hours, and the usefulness of the above method for the diagnosis of bone metastasis from prostatic cancer was evaluated. In cases in which increased activity was found in the upper and lower lumbar vertebrae by routine bone scintigraphy but no abnormality was seen by early whole body bone scintigraphy, senile degenerative bone changes such as spondylosis deformance were observed by bone radiography. In cases with multiple bone metastases, abnormal multiple accumulations were found by both early whole body bone scintigraphy and routine bone scintigraphy. In addition, in cases showing super bone scan, high accumulation in the skeletal system had already been detected by early whole body bone scintigraphy. When the courses before and after treatment in nine cases of multiple bone metastases were passaged from the results of early whole body bone scintigraphy and from changes in tumor markers (prostatic specific antigen, [gamma]-semino protein and prostatic acid phosphatase), increased activity and the appearance of new hot spots as well as an increase in tumor markers were detected by early whole body scintigraphy in three of the four advanced cases, whereas decreased accumulations and a decrease in and normalization of tumor markers were observed in five improved cases.

    2013-12-01

    Although substantial increases in survival rates among children diagnosed with cancer have been observed in recent decades, survivors are at risk of developing therapy-related chronic health conditions. Among children and adolescents treated for cancer, acquisition of peak bone mass may be compromised by cancer therapies, nutritional deficiencies, and reduced physical activity. Accordingly, failure to accrue optimal bone mass during childhood may place survivors at increased risk for deficits in bone density and fracture in later life. Current recommendations for the treatment of bone density decrements among cancer survivors include dietary counseling and supplementation to ensure adequate calcium and vitamin D intake. Few strategies exist to prevent or treat bone loss. Moving forward, studies characterizing the trajectory of changes in bone density over time will facilitate the development of interventions and novel therapies aimed at minimizing bone loss among survivors of childhood cancer.

  8. Cancer pain: A critical review of mechanism-based classification and physical therapy management in palliative care

    Full Text Available Mechanism-based classification and physical therapy management of pain is essential to effectively manage painful symptoms in patients attending palliative care. The objective of this review is to provide a detailed review of mechanism-based classification and physical therapy management of patients with cancer pain. Cancer pain can be classified based upon pain symptoms, pain mechanisms and pain syndromes. Classification based upon mechanisms not only addresses the underlying pathophysiology but also provides us with an understanding behind patient′s symptoms and treatment responses. Existing evidence suggests that the five mechanisms - central sensitization, peripheral sensitization, sympathetically maintained pain, nociceptive and cognitive-affective - operate in patients with cancer pain. Summary of studies showing evidence for physical therapy treatment methods for cancer pain follows with suggested therapeutic implications. Effective palliative physical therapy care using a mechanism-based classification model should be tailored to suit each patient′s findings, using a biopsychosocial model of pain.

    Cancer pain is a serious health problem, and imposes a great burden on the lives of patients and their families. Pain can be associated with delay in treatment, denial of treatment, or failure of treatment. If the pain is not treated properly it may impair the quality of life. Neuropathic cancer pain (NCP) is one of the most complex phenomena among cancer pain syndromes. NCP may result from direct damage to nerves due to acute diagnostic/therapeutic interventions. Chronic NCP is the result of treatment complications or malignancy itself. Although the reason for pain is different in NCP and noncancer neuropathic pain, the pathophysiologic mechanisms are similar. Data regarding neuropathic pain are primarily obtained from neuropathic pain studies. Evidence pertaining to NCP is limited. NCP due to chemotherapeutic toxicity is a major problem for physicians. In the past two decades, there have been efforts to standardize NCP treatment in order to provide better medical service. Opioids are the mainstay of cancer pain treatment; however, a new group of therapeutics called coanalgesic drugs has been introduced to pain treatment. These coanalgesics include gabapentinoids (gabapentin, pregabalin), antidepressants (tricyclic antidepressants, duloxetine, and venlafaxine), corticosteroids, bisphosphonates, N-methyl-D-aspartate antagonists, and cannabinoids. Pain can be encountered throughout every step of cancer treatment, and thus all practicing oncologists must be capable of assessing pain, know the possible underlying pathophysiology, and manage it appropriately. The purpose of this review is to discuss neuropathic pain and NCP in detail, the relevance of this topic, clinical features, possible pathology, and treatments of NCP.

    This literature review explores the effectiveness of massage therapy to reduce cancer pain. As part of the review, systematic literature search was carried out on various electronic databases and specialised journals. Included are 19 research-based articles and 8 review articles. The review suggests that cancer has become a common health problem in the world and most of the cancer patients are going through intense and unbearable pain. Studies have reported that most of the cancer patients' pain reduced with therapeutic massage. Seventy-three per cent of cancer patients use massage therapy in the USA. Few studies are available in the context of the developing world related to massage therapy and we could not find any study in the Pakistani context. There is a need to conduct an interventional study about the effectiveness of massage therapy to control cancer pain in developing countries such as Pakistan.

    Bone is one of the most common metastatic sites of breast cancer, but the underlying mechanisms remain unclear, in part due to an absence of advanced platforms for cancer culture and study that mimic the bone microenvironment. In the present study, we integrated a novel stereolithography-based 3D printer and a unique 3D printed nano-ink consisting of hydroxyapatite nanoparticles suspended in hydrogel to create a biomimetic bone-specific environment for evaluating breast cancer bone invasion. Breast cancer cells cultured in a geometrically optimized matrix exhibited spheroid morphology and migratory characteristics. Co-culture of tumor cells with bone marrow mesenchymal stem cells increased the formation of spheroid clusters. The 3D matrix also allowed for higher drug resistance of breast cancer cells than 2D culture. These results validate that our 3D bone matrix can mimic tumor bone microenvironments, suggesting that it can serve as a tool for studying metastasis and assessing drug sensitivity. From the Clinical Editor: Cancer remains a major cause of mortality for patients in the clinical setting. For breast cancer, bone is one of the most common metastatic sites. In this intriguing article, the authors developed a bone-like environment using 3D printing technology to investigate the underlying biology of bone metastasis. Their results would also allow a new model for other researchers who work on cancer to use.

  15. Acute Cavernous Sinus Syndrome from Metastasis of Lung Cancer to Sphenoid Bone

    Full Text Available Cavernous sinus syndrome is a rare entity in oncology reported only in occasional case reports. Optimal therapy is thus poorly defined with rapidly progressive disease dominating the picture. Management includes prompt diagnosis, attempts at stabilization of cranial nerve function, and aggressive control of central pain syndrome. Here, we report cavernous sinus syndrome secondary to the original squamous cell carcinoma of the lung. With common presenting causes of this syndrome being infection, thrombosis or tumor, it might seem that metastatic tumor would be expected in a patient with a cancer diagnosis. What was not so expected was the extremely rapid progression from mild headache and mild trigeminal neuralgia with negative-contrast head CT to a massive, destructive lesion involving several skull bones and skull base, only 3 weeks later. In addition, the patient was severely immunosuppressed at the completion of induction chemotherapy. Infectious processes, although unlikely, were considered, as aggressive cancer therapy (including high-dose steroids and radiation therapy had no impact on this disease. Despite accurate localization, the aggressive nature of this disease with massive bone destruction and dural thickening limited any chance of a durable control. We discuss the process of evaluation, diagnosis and treatment of symptoms and the importance of a team approach to best palliate these unfortunate patients.

    Objective: To explore the efficacy of Tongkuaixiao Babu plaster (痛块消巴剂, TKXBBP)in treating cancer pain. Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL),and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn't any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0.05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05)and satisfaction rate, with significant difference between the treated and the control groups (P<0.01). Conclusion: TKXBBP's effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.

    2012-01-01

    Full Text Available Breast cancer is a leading cancer diagnosis among women worldwide, with more than 210,000 new cases and 40,000 deaths per year in the United States. Pain, anxiety, and depression can be significant factors during the course of breast cancer. Pain is a complex experience with sensory, affective, and cognitive dimensions. While depression and anxiety symptoms are relatively common among breast cancer patients, little is known about the relation between these psychiatric factors and distinct components of the pain experience. In the present study 60 females presenting to an NCI-designated Cancer Center with newly diagnosed breast cancer completed the Center for Epidemiological Studies 10-item Depression Scale, the State Instrument of the Spielberger State-Trait Anxiety Inventory, and the McGill Pain Questionnaire. Findings indicate that anxiety and depression are common among newly diagnosed breast cancer patients; furthermore, patients experience an appreciable amount of pain even before oncologic treatment starts. State anxiety serves as a predictor of the sensory dimension of the pain experience, whereas depression serves as a predictor of the affective dimension of the pain experience.

    Full Text Available  Oncogenic osteomalacia (OOM is a rare paraneoplastic syndrome induced by tumor produced phosphaturic factors, i.e. phosphatonins. The disorder is characterized by renal tubular phosphate loss, secondary to this process hypophosphatemia and defective production of active form of vitamin D. The clinical course of oncogenic osteomalacia is characterized by bone pain, pathological fractures, muscle weakness and general fatigue. Osteomalacia-associated tumors are usually located in the upper and lower limbs, with half of the lesions primarily situated in the bones. Most of them are small, slow-growing tumors. Their insignificant size and various location coupled with rare occurrence of the disease and non-specificity of clinical symptoms lead to difficulties in reaching a diagnosis, which is often time-consuming and requires a number of additional tests. The average time between the appearance of the first symptoms and the establishment of an accurate diagnosis and the beginning of treatment is over 2.5 years. The aim of this study is to discuss the pathophysiology of disease symptoms, pathomorphology of tumors, diagnostic methods and treatment of oncogenic osteomalacia.

    Various radioisotopes conjugated to pyrophosphate analogues have been developed for systemic metabolic radiotherapy. Samarium-153-EDTMP is a 1:1 complex of radioactive Samarium-153 and a Tetraphosphonate (ethylenediamine-tetramethylene phosphonic acid (EDTMP)). Samarium Sm-153-EDTMP has a high affinity for skeletal tissue and concentrates by chemiabsorption in areas of enhanced metabolic activity, where it associates with the hydroxyappetite crystal. Samarium-153 Lexidronam (Quadramet (R)) has been approved for routine use by the FDA. This agent offers several advantages over other agents used for palliating bone pain. Due to its half-life of 46 hours and its beta emissions, a high dose rate can be delivered to regions adjacent to enhanced osteoblastic activity over a short period of time with little residual long term activity being left in the bone marrow. This paper summarizes both animal studies and clinical studies performed with this agent. Special emphasis will be given to the pivotal Phase-III clinical studies and subsequent studies performed since its approval by the FDA. Special considerations regarding appropriate selection of patients, preparation, follow-up of patients and adjustments to the usual recommended dose (1 mCi/Kg (35 Mbq/kg)) will be discussed. Current and future treatment options utilizing Sm-153-EDTMP with other pharmaceuticals appear promising and will substantially extend its use into new areas. In addition, because it also emits a 103 keV gamma ray which makes it suitable for imaging and assessment of biodistribution, dosimetric application are possible in the future.

    Cancer becomes the leading cause of deaths worldwide, including breast cancer, prostate cancer and lung cancer that preferentially metastasize to bone and bone marrow. Bisphosphonates (BPs) have been used successfully for many years to reduce the skeletal complications related with the benign and malignant bone diseases that are characterized by enhanced osteoclastic bone resorption. Nitrogen-containing bisphosphonates (N-BPs) have also been demonstrated to exhibit direct anti-tumour effects. BPs binds avidly to the bone matrix, and released from matrix during bone resorption process, BPs are internalized by the osteoclasts where they interfere with biochemical pathways and induce osteoclast apoptosis. BPs also antagonizes the production of osteoclast and promotes the osteoblasts proliferation. Currently, Zoledronic acid is widely used as one of the BP having high bone specificity and potential to inhibit the osteoclast-mediated bone resorption. In addition to inhibition of cell multiplication and initiation of apoptosis in cultured cancer cells, they also interfere with adhesion of cancer cells to the bone matrix and inhibit cell migration and invasion. Pathophysiology and current target therapies like conjugate of BPs with liposomes, nanoparticle used for the treatment of bone cancer is reviewed in this article along with the use of different BPs.

    To develop a radiopharmaceutical for the palliation of painful bone metastases based on the concept of bifunctional radiopharmaceuticals, we synthesized a bisphosphonate derivative labeled with rhenium-186 ({sup 186}Re) that contains a hydroxyl group at the central carbon of its bisphosphonate structure, we attached a stable {sup 186}Re-MAMA chelate to the amino group of a 4-amino butylidene-bisphosphonate derivative [N-[2-[[4-[(4-hydroxy-4,4-diphosphonobutyl)amino]-4-oxobutyl] -2-thioethylamino]acetyl]-2-aminoethanethiolate] oxorhenium (V) ({sup 186}Re-MAMA-HBP) and we investigated the effect of a hydroxyl group at the central carbon of its bisphosphonate structure on affinity for hydroxyapatite and on biodistribution by conducting a comparative study with [N-[2-[[3-(3,3-diphosphonopropylcarbamoyl)propyl]-2-thioethylamino]acetyl] -2-a minoethanethiolate] oxorhenium (V) ({sup 186}Re-MAMA-BP). The precursor of {sup 186}Re-MAMA-HBP, trityl (Tr)-MAMA-HBP, was obtained by coupling a Tr-MAMA derivative to 4-amino-1-hydroxybutylidene-1,1-bisphosphonate. {sup 186}Re-MAMA-HBP was prepared by a reaction with {sup 186}ReO{sub 4} {sup -} and SnCl{sub 2} in citrate buffer after the deprotection of the Tr groups of Tr-MAMA-HBP. After reversed-phase high-performance liquid chromatography, {sup 186}Re-MAMA-HBP had a radiochemical purity of over 95%. Compared with {sup 186}Re-MAMA-BP, {sup 186}Re-MAMA-HBP showed a greater affinity for hydroxyapatite beads in vitro and accumulated a significantly higher level in the femur in vivo. Thus, the introduction of a hydroxyl group into {sup 186}Re complex-conjugated bisphosphonates would be effective in enhancing accumulation in bones. These findings provide useful information on the design of bone-seeking therapeutic radiopharmaceuticals.

    Clinicians in acute care settings are often called upon to manage cancer pain unrelieved by medications. Cognitive-behavioral strategies, such as relaxation and imagery, are recommended for cancer pain management; however, there appear to be individual differences in their effects. This pilot study examined variation in pain outcomes achieved with progressive muscle relaxation (PMR) and analgesic imagery interventions among hospitalized patients with cancer pain, and assessed the influence of...

    Full Text Available Background: Cancer pain is a complex multidimensional construct. Physicians use a patient-centered approach for its effective management, placing a great emphasis on patient self-reported ratings of pain. In the literature, studies have shown that a patient′s ethnicity may influence the experience of pain as there are variations in pain outcomes among different ethnic groups. At present, little is known regarding the effect of ethnicity on the pain experience of cancer patients; currently, there are no systematic reviews examining this relationship. Materials and Methods: A systematic search of the literature in October 2013 using the keywords in Group 1 together with Group 2 and Group 3 was conducted in five online databases (1 Medline (1946-2013, (2 Embase (1980-2012, (3 The Cochrane Library, (4 Pubmed, and (5 Psycinfo (1806-2013. The search returned 684 studies. Following screening by inclusion and exclusion criteria, the full text was retrieved for quality assessment. In total, 11 studies were identified for this review. The keywords used for the search were as follows: Group 1-Cancer; Group 2- Pain, Pain measurement, Analgesic, Analgesia; Group 3- Ethnicity, Ethnic Groups, Minority Groups, Migrant, Culture, Cultural background, Ethnic Background. Results: Two main themes were identified from the included quantitative and qualitative studies, and ethnic differences were found in: (1 The management of cancer pain and (2 The pain experience. Six studies showed that ethnic groups face barriers to pain treatment and one study did not. Three studies showed ethnic differences in symptom severity and one study showed no difference. Interestingly, two qualitative studies highlighted cultural differences in the perception of cancer pain as Asian patients tended to normalize pain compared to Western patients who engage in active health-seeking behavior. Conclusion: There is an evidence to suggest that the cancer pain experience is different between

    Lung cancer remains a major worldwide health problem and patients have high rate of metastasis including bone. Although pathologic characteristics of this disease are clear and well established, much remains to be understood about this tumor, particularly at the molecular signaling level. Secreted signaling molecules of the Wnt family have been widely investigated and found to play a prominent role to induce human malignant diseases, such as breast and prostate cancer. A variety of studies have also demonstrated that the Wnt signaling pathway is closely associated with bone malignancies including osteosarcoma, multiple myeloma, and breast or prostate cancer induced bone metastasis. The aim of this review is to provide a summary regarding the role of the Wnt signaling pathway in lung cancer and bone metastasis, highlighting the aberrant activation of Wnt in this malignancy. We also discuss the potential therapeutic applications for the treatment of lung cancer and cancer induced bone metastasis targeting the Wnt pathway.

    Vertebral compression fractures (VCFs) are common complications of osteoporosis. The expansion of VCFs with a Sky Bone Expander is a new procedure which improves kyphotic deformities and decreases pain associated with VCFs. The purpose of this study was to investigate the preliminary results for the treatment of painful osteoporotic VCFs with a Sky Bone Expander. Twenty-six patients with pain-causing VCFs were treated with a Sky Bone Expander. This operation involved the percutaneous insertion of the Sky Bone Expander into a fractured vertebral body transpedicularly. Following the expansion, the Sky Bone Expander was contracted and removed, resulting in a cavity to be filled with bone cement. All fractures were analyzed for improvement in sagittal alignment. Clinical complications, pain relief and ambulation status were evaluated 1 day, 1 week, 1 month, and 3 months after the operation. Twenty-four hours after the operation, all the patients treated experienced some degree of pain relief. In addition, no postoperative neurologic complications were noted. The average operative time was 42.4 {+-} 15.5 min per vertebra. Moreover, an average cement volume of 3.5 mL (range, 2.5 {+-} 5.0 mL) was injected per vertebra. The average anterior height was 18.4 {+-} 5.1 mm preoperatively and 20.5 {+-} 5.3 mm postoperatively (p < 0.01). Furthermore, the average midline height was 15.5 {+-} 5.2 mm preoperatively and 18.9 {+-} 4.0 mm postoperatively (p < 0.01). The Cobb angle improved from 18.5 {+-} 8.2 degrees preoperatively to 9.2 {+-} 4.0 degrees postoperatively (p < 0.01). The Visual Anabog Scale scores decreased from 7.7 {+-} 1.8 points preoperatively to 3.1 {+-} 2.0, 2.9 {+-} 1.7, 2.6 {+-} 1.5 and 2.9 {+-} 11.3 after 1 day, 1 week, 1 month and 3 months after the operation, respectively. Cement extrusion was observed in four patients without any neurologic symptoms. As a result of this study, we can postulate that the expansion of compressed vetrebra with a Sky Bone Expander

    Objective:To evaluate the effect of down-regulation of Nav1.7 on the activation of astrocytes and microglia in DRG of rats with cancer pain, and explore the transmission of the nociceptive information.Methods:Lentiviral vector harboring RNAi sequence targeting theNav1.7gene was constructed, and Walker 256 breast cancer cell and morphine was injected to build the bone cancer pain model and morphine tolerance model in rats. Lentiviral vector was injected. Rats in each model were divided into 4 groups: model group, PBS group, vehicle group and LV-Nav1.7 group. The expression levels of GFAP and OX42 in dorsal root ganglia (DRG) were measured.Results: After the animal model was built,the level of Nav1.7, GFAP and OX42 was improved obviously with the time prolonged, which was statistically significant (P<0.05). The expression level of GFAP and OX42 in the DRG in the LV-Nav1.7 group declined obviously compared to the model group, PBS group and vehicle group (P<0.05).Conclusions:Intrathecal injection of Navl.7 shRNA lentiviral vector can reduce the expression of Nav1.7 and inhibit the activation of astrocytes and microglia in DRG. The effort is also effective in morphine tolerance bone cancer pain model rats.

    This case report series describes eight patients (four patients with pancreatic carcinoma, one patient with hepatocellular carcinoma, one patient with gastric and rectal carcinoma, one with sigmoid colon cancer, and one with rectal cancer), whose abdominal cancer pain was treated with intravenous phentolamine infusion at 80 mg x day(-1) for 2 days. All but one of the patients had already been treated with opioids. All eight patients complained of severe abdominal pain; in five patients the pain radiated to the back, and there was associated anal pain in two patients. Analgesia was achieved in three patients; pain alleviation was obtained in four patients, but was not sustained in two of these four patients; and the treatment in one patient could not be judged for efficacy because epidural morphine was used together with the phentolamine. Adverse effects of phentolamine were tachycardia and/or hypotension.
