    This is an update of the review published in Issue 4, 2003. Bone metastasis cause severe pain as well as pathological fractures, hypercalcaemia and spinal cord compression. Treatment strategies currently available to relieve pain from bone metastases include analgesia, radiotherapy, surgery, chemotherapy, hormone therapy, radioisotopes and bisphosphonates. To determine efficacy and safety of radioisotopes in patients with bone metastases to improve metastatic pain, decrease number of complications due to bone metastases and improve patient survival. We sought randomised controlled trials (RCTs) in MEDLINE, EMBASE, CENTRAL, and the PaPaS Trials Register up to October 2010. Studies selected had metastatic bone pain as a major outcome after treatment with a radioisotope, compared with placebo or another radioisotope. We assessed the risk of bias of included studies by their sequence generation, allocation concealment, blinding of study participants, researchers and outcome assessors, and incomplete outcome data. Two review authors extracted data. We performed statistical analysis as an "available case" analysis, and calculated global estimates of effect using a random-effects model. We also performed an intention-to-treat (ITT) sensitivity analysis. This update includes 15 studies (1146 analyzed participants): four (325 participants) already included and 11 new (821 participants). Only three studies had a low risk of bias. We observed a small benefit of radioisotopes for complete relief (risk ratio (RR) 2.10, 95% CI 1.32 to 3.35; Number needed to treat to benefit (NNT) = 5) and complete/partial relief (RR 1.72, 95% CI 1.13 to 2.63; NNT = 4) in the short and medium term (eight studies, 499 participants). There is no conclusive evidence to demonstrate that radioisotopes modify the use of analgesia with respect to placebo. Leucocytopenia and thrombocytopenia are secondary effects significantly associated with the administration of radioisotopes (RR 5.03; 95% CI 1.35 to

    Bone pain associated with advanced prostate and other cancers is a frequent and significant complication. Pharmaceutical therapy of bone pain includes nonsteroidal analgesics and opiates. While external beam radiation therapy remains the mainstay of pain palliation of solitary lesions, bone-seeking radiopharmaceuticals have entered the armamentarium for the treatment of multiple osseous metastases. The 3 radioisotopes currently approved for treatment of pain (strontium-89/(89)Sr, samarium-153/(153)Sm and rhenium-186/(186)Re) are discussed in this review including the approved dose, method of administration and indications for use.

    Cancer patients who develop bone metastases are an estimated 60 to 84% . Of these 79% experienced pain syndromes are difficult to manage, of which 50% die without adequate pain relief and with a poor quality of life. Therefore, it is necessary to have accessible and effective medications for the management of this condition. The pathophysiology of pain in bone is reviewed and the drugs used most frequently in the management of this type of cancer pain are described. Furthermore an algorithm of 6 steps is presented and can guide the physician when making a therapeutic decision. (author) [es

    Bone metastases are the most frequent cause of cancer-induced bone pain (CIBP). Although palliative radiotherapy and pharmacotherapy conducted according to World Health Organization (WHO) analgesic ladder are the treatment of choice for CIBP reduction, these methods are not always successful, especially with regard to alleviation of incidental pain. Antiresorptive drugs (bisphosphonates) are able to inhibit bone destruction (loss), proliferation of cancer cells and angiogenesis, but their prolonged use may lead to a spectrum of adverse effects. In this paper, types of bone metastases, their complications, as well as diagnostic and therapeutic implications are presented. Moreover, the paper discusses presently used CIBP treatment methods and research directions for future methods, with special focus on bone metastases. Copyright © 2017 Elsevier Masson SAS.

    Metabolic radionuclide therapy of metastatic bone pain using 89 SrCl (metastron) is discussed in historical point of view and in perspective. Also its place among the conventional therapeutic options for bone pain palliation and the perspectives for an improvement in its efficiency is evaluated. Pharmacokinetics of 89 SrCl and the mechanism of its impact on pathophysiology of metastatic bone pain were considered. In regard to an optimal selection of patients, that would benefit most of the therapy, the indications, criteria and effectiveness of the therapy in patients in different stages of the malignancy or with different bone metastases were analyzed. In this article are also discussed current changes in treatment approaches. They consist in earlier administration of metastron in the course of the neoplastic disease and in more accurate selection of patients with predominant osteoblastic bone metastases. Radionuclide metabolic therapy has some advantages to conventional therapeutic approaches that are considered in this article. One of them is the opportunity for combined therapy using 89 SrCl and biphosphonates and/ or chemotherapy Together these approaches have a synergistic effect inducing better efficacy in bone pain palliation, delay in new incidence of metastatic bone process, decrease in metastatic bone related complications and may be a better life expectancy.

    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.

    Phosphorus-32 ( 32 P) is a routinely used bone pain palliation agent at our institute due to its cost, availability and proven efficacy with mild and self limiting myelo-suppression. Vitamin D is known to de-differentiate tumors and supposed to enhance calcium deposition onto metastatic foci with a hope of reducing the marrow effects. A pilot study showing an increase in the 99m Tc-MDP uptake by skeletal metastatic foci, using single pulse dose of Vitamin D, in some of the patients preceded this study and found the basis for this study. The aim of this study was to evaluate the role of 32 P alone and in combination with vitamin D in the palliation of bone pain from osseous metastases and to look for its clinical efficacy and reduction in marrow suppression in our clinical environment. 62 patients with extensive osteoblastic bone metastases were randomly divided into 3 groups. Group A received 32 P alone, group B combination therapy of 32 P and Vitamin D and group C Vitamin D alone. All these patients were evaluated by a standard protocol on broad parameters of pain reduction, reduction in analgesic consumption, improvement in quality of life and effect on bone marrow suppression at the end of 4th and 8th week post-therapy. Favorable response (≥25%) to treatment was recorded in 55% of cases in-group A, 81% in- group B and 9% in-group C. Reduction in pain score of 50% to 100% were obtained in two cases in group A and 10 in group B. A decrease in pain of 26% to 50% and ≤ 25% was observed in 10 (45%) and 4 (18%) cases respectively in group A, and 8 (36%) and 2 (9%) cases respectively in group B. Analgesic consumption was reduced in both the groups of 32 P, comparatively more in group B. The improvement in mobility and quality of life was observed to be better in group B than A and C. A decrease of white blood cells, hemoglobin level and platelets counts was observed in both groups of 32 P but no significant difference was noted in group A and B was noted at the end

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

    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.

    While bisphosphonates are indicated for prevention of skeletal-related events, radionuclide therapy is widely used for treatment of painful bone metastases. Combined radionuclide therapy with bisphosphonates has demonstrated improved effectiveness in achieving bone pain palliation in comparison to mono therapy with radionuclides or bisphosphonates alone. However, there are conflicting reports as to whether bisphosphonates adversely influence skeletal uptake of the bone-seeking radiotracers used for therapy. Recent studies analyzing influence of Zoledronic acid on total bone uptake of Samarium-153 EDTMP (Sm-153 EDTMP) by measuring cumulative urinary activity of Sm-153 on baseline study, as well as in combination with bisphosphonates (administrated 48 hours prior to Sm-153) did not provide any statistically significant difference in urinary excretion of Sm-153 between the two groups. It may be noted that the exact temporal sequence of bisphosphonate administration vis a vis radionuclide therapy has not yet been studied. One of the side effects of bisphosphonates is transient flare effect on bone pain. Radionuclide therapy may also have similar side effect. Keeping in view the above the current study was designed with the main objective of determining the exact timing of bisphosphonate administration in patients receiving combined therapy so as to achieve optimal efficacy of bone pain palliation. Ninety-three patients suffering from metastatic bone pain who received combination therapy with Sm-153 oxabifore (an analog of Sm-153 EDTMP) and Zoledronic acid were divided into three groups according to the timing of Zoledronic acid administration: Group I: 39 patients who received Zoledronic acid 7 or more days prior to Sm-153 oxabifore treatment; Group II: 32 patients who received Zoledronic acid 48-72 hours prior to Sm-153 oxabifore treatment and Group III: 22 patients who received Zoledronic acid 7 days after Sm-153 oxabifore treatment. Sm-153 oxabifore was administered

    Skeletal conditions are common causes of chronic pain and there is an unmet medical need for improved treatment options. Bone pain is currently managed with disease modifying agents and/or analgesics depending on the condition. Disease modifying agents affect the underlying pathophysiology...... of the disease and reduce as a secondary effect bone pain. Antiresorptive and anabolic agents, such as bisphosphonates and intermittent parathyroid hormone (1-34), respectively, have proven effective as pain relieving agents. Cathepsin K inhibitors and anti-sclerostin antibodies hold, due to their disease...... modifying effects, promise of a pain relieving effect. NSAIDs and opioids are widely employed in the treatment of bone pain. However, recent preclinical findings demonstrating a unique neuronal innervation of bone tissue and sprouting of sensory nerve fibers open for new treatment possibilities....

    To educate is a difficult task but its results make efforts worthwhile. Many patients in Peru suffer from intractable bone pain due to metastases. Since 1993 radionuclides were used to palliate bone pain due to metastases in Peru. First, with the help of the IAEA, Peru participated in a clinical trial using Phosphorus 32 and Strontium 89. Then, efforts were performed to produce Samarium 153 EDMTP locally, which was achieved in 1995. Nevertheless, years passed and Samarium use did not increase proportionally to the needs of people with cancer and bone pain, mainly the poor. Educational strategies have been proven useful for delivering solutions to many health problems in other diseases and also in cancer. Health education makes patients and their relatives assume responsible care of their problems. The purpose of this work was to increase Samarium EDTMP use as palliative treatment in patients with bone pain due to metastases, using educational strategies as means to change attitudes towards this health problem. In September 2003, a task group conducted studies in order to apply several methods to achieve the goal of increasing Samarium EDTMP use. Educational strategies employed were performed to provide verbal and written information to patients, physicians, medical students, residents, pain specialists, oncologists and neurologists, as well as general public. Verbal information included radio interviews, television spots and a phone number (in charge of two secretaries, prepared for answering and if not possible, a physician was in charge of attending patient consultation), e-mail and a web page for consultation. Written material was delivered to several newspapers, including clinical use of Samarium, possibilities of being elected for treatment, benefits and risks and a photography of the product. Politics of the institution producing Samarium changed, in order to achieve minimum cost of the product and it was delivered to all publics at the lowest cost for a year

    The objective of the study was to evaluate the treatment effectiveness with 188Re-HEDP in a group of 27 patients, who had received 36 doses. A pharmaceutical care programme was also added in order to improve drug follow-up after treatment. Two levels of doses were administered: 30 or 60 mCi. Initially a trace dose was given in order to estimate the therapeutic dose, which was individualise according to bone uptake of the radiopharmaceutical. Bone uptake was determined measuring radioactivity in urine samples (0, 1, 2, 4 and 6 hs), because the radiopharmaceutical showed only renal elimination. Multiple dose schedules with with 3 months between both doses were also tried. Seventy two percent showed an algesic effect during the first week post-treatment, with was kept during one month, while seven tenn (17%) percent of the patients the effect was kept for two of more months. Opioid analgesic (third level of OMS scale) were diminished in eighty two percent of the patients and AINES drugs in seventy one percent. The pharmaceutical care programme also showed the importance of the radio pharmacist role to improve treatment outcomes. 188Re-HEDP effectiveness was achieved in 100% of the patients, but with different pain palliation response in time and/or drug intake, with a suitable radiological safety

    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

    Full Text Available Abstract In adults, bone is the preferential target site for metastases from primary cancers of prostate, breast, lungs and thyroid. The tendency of these cancers to metastasize to bone is determined by the anatomical distribution of the blood vessels, by the genetic profile of the cancer cells and by the biological characteristics of the bone microenvironment that favour the growth of metastatic cells of certain cancers. Metastases to bone may have either an osteolytic or an ostoblastic phenotype. The interaction in the bone microenvironment between biological factors secreted by metastatic cells, and by osteoblasts and osteoclasts, and the osteolytic and osteoblastic factors released from the organic matrix mediate a vicious cycle characterized by metastatic growth and by ongoing progressive bone destruction. This interaction determines the phenotype of the metastatic bone disease.

    Metastatic bone disease is a major sequela of several solid cancers; the breast, prostate, lung, kidney and thyroid etc. Bone pain is a common symptom in advancing malignancy and often determines the quality of life in the later stages of disease. Management of bone pain remains palliative at present. With the improved cancer survival resulting from advances in cancer management, the population of patients seeking relief of bone pain has increased. Radiopharmaceutical therapy offers potential pain relief with minimal adverse effects. The purpose of this study was to assess the current status of radiopharmaceutical therapy for bone pain palliation in the Philippines. To date, no study has been done on bone pain palliation therapy. The study population included all cancer patients with bone metastasis presenting with chronic bone pain who were subjected to radiopharmaceutical therapy for bone pain palliation in the different medical centers and hospitals in the Philippines. The clinical histories of the patients were reviewed. The specific radiopharmaceutical and corresponding doses used for the said therapies were also noted. The respondents were inquired of the effectiveness of the therapy in relieving bone pain and duration of the response to the therapy. The complete blood count, before and after the therapy, were retrieved. The approximate cost of the therapy was also inquired and was then compared with the cost of different treatment modalities. Over the years only six radiopharmaceutical therapies have been performed in the Philippines (three male patients with prostate cancer, two female patients with breast cancer and one female patient with renal cancer). All had multiple bone metastases on bone scintigraphy and presented with chronic bone pain, which were not adequately controlled by other treatment modalities such as analgesics, bisphosphonates, chemotherapy, hormonal therapy and radiation therapy. Four subjects were subjected to Strontium-89 chloride (Sr

    Full Text Available The primary carcinoma may secondarily invade bone tissue through direct extensions, blood circulation or lymphatic transportation particulary when it is arising from breast, prostate, kidney, thyroid and lung. Metastatics tumors of bone are more common than primary tumor of bone. The most common tumor, which metastasizes into bone, is the breast adenocarcinoma. Some metastatic tumors of bone including the breast cancer, may appear only as a destructive lesion, while prostatic carcinoma is osteoblastoma. The metastasis is mostly appeared in skull, vertebrae, pelvic, femur and humerus bones. The first metastatic syndrome is usually the affected bone pain and pathologic fractures are commonly caused by osteometastasis

    Two patients with carotid body paraganglioma developed bone metastases 3 and 6 years respectively after surgical excision of the primary tumors. Plain radiographs showed ill-defined metastatic lesions. Scintigram using radiolabeled metaiodobenzylguanidine, an analogue of noradrenaline that is taken up by neurosecretary granules, showed an abnormal accumulation in the corresponding metastatic lesion. Histologically, nests of epithelioid cells with clear cytoplasm and pyknotic nuclei and abundant collagen fibers were observed within destroyed trabeculae. Treatment including external radiation and surgery provided pain relief and early local disease control. (orig.)

    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.

    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

    Full Text Available A variety of radionuclides continue to be investigated and/or clinically used for different therapeutic applications in nuclear medicine. The choice of a particular radionuclide with regard to appropriate emissions, linear energy transfer (LET, and physical half-life, etc., is dictated to a large extent by the character of the disease (e.g., solid tumor or metastatic disease, and by the carrier to selectively transport the radionuclide to the desired site. An impressive body of information has appeared in the recent literature that addresses many of these considerations. This article summarizes and discusses the role of high-LET electron emitters and their advantage in the treatment of cancer or for other disorders in specific situations. Areas such as bone pain palliation, bone malignancy therapy, and radiation synovectomy are covered in greater detail. Projections are made as to the future directions and progress in these areas. A discussion of the various issues related to the selection criteria that are useful for choosing the appropriate radionuclide for a particular application is included. Use of high-LET electron emitters is discussed in greater detail, with particular emphasis on the use of conversion electron emitter tin-117m for various therapeutic applications.Uma variedade de radionuclídeos continua a ser investigada e/ou clinicamente utilizada para diferentes aplicações terapêuticas em medicina nuclear. A escolha de um radionuclídeo, considerando-se sua emissão apropriada, transferência linear de energia (LET e meia-vida física é determinada na maior parte pelo caráter da doença (p.ex., tumor sólido ou doença metastática, e pelo carreador que transporta o radionuclídeo seletivamente para o sítio desejado. Um notável conjunto de informações voltadas para essas considerações tem aparecido na literatura recente.

    Radiotherapy often is used for palliation of bone pain from metastatic cancer of the prostate but an objective evaluation of its efficacy in a large series of patients is unavailable. We report the results of external beam irradiation in 62 patients who had bone pain secondary to stage D carcinoma of the prostate. The variables used to judge pain before and after radiotherapy included subjective evaluation of pain, status of activity and quantitation of analgesic use. Complete relief of pain was achieved in 26 patients (42 per cent), partial relief in 22 (35 per cent) and no relief in 14 (23 per cent). On the basis of our experience external beam irradiation is useful palliative therapy for pain from metastatic cancer of the prostate

    Thermal neutron activation of 152 Sm [ 152 Sm(n,γ) 153 Sm] using natural or isotopically enriched (by 152 Sm) samarium target is the established route for production of 153 Sm used for preparation of 153 Sm-EDTMP for pain palliation in cancer patients with disseminated bone metastases. However, some long-lived radionuclidic contaminants of Eu, such as, 154 Eu (t ½ =8.6y) are also produced during the target activation process. This leads to detectable amount of Eu radionuclidic contaminants in patients' skeleton even years after administration with therapeutic doses of 153 Sm-EDTMP. Further, the presence of such contaminants in 153 Sm raises concerns related to radioactive waste management. The aim of the present study was to develop and demonstrate a viable method for large-scale purification of 153 Sm from radionuclidic contaminants of Eu. A radiochemical separation procedure adopting electroamalgamation approach has been critically evaluated. The influence of different experimental parameters for the quantitative removal radionuclidic contaminants of Eu from 153 Sm was investigated and optimized. The effectiveness of the method was demonstrated by purification of ~37 GBq of 153 Sm in several batches. As a proof of concept, 153 Sm-EDTMP was administered in normal Wistar rats and ex vivo γ-spectrometry of bone samples were carried out. After carrying out the electrolysis under the optimized conditions, the radionuclidic contaminants of Eu could not be detected in purified 153 Sm solution by γ-spectrometry. The overall yield of 153 Sm obtained after the purification process was >85%. The reliability of this approach was amply demonstrated in several batches, wherein the performance remained consistent. Ex vivo γ-spectrometry of bone samples of Wistar rats administered with 153 Sm-EDTMP (prepared using electrochemically purified 153 Sm) did not show photo peaks corresponding to radionuclidic contaminants of Eu. A viable electrochemical strategy for the large

    Basal cell carcinoma (BCC) is the most common carcinoma in the community, but the incidence of metastatic events is exceedingly low. The few reported cases most often appear in regional nodes or the lungs, and patients usually exhibit multiple concurrent organs of spread at the time of diagnosis. We report a case of primary BCC located on the left forehead of a 48-year-old man, which metastasized exclusively to the bone and bone marrow, associated with hematologic disorders. A short review of the literature is included. Pathologic examination of the tumor located on the left forehead showed BCC. The patient underwent two surgical excisions because of local recurrence. Three years later, the patient developed a bicytopenia (anemia and thrombocytopenia). The bone marrow biopsy revealed metastasis of BCC. There were no abnormal findings in the other routine laboratory tests and radiologic investigations, except for the bone scan which showed multifocal skeletal metastases. The patient received two cycles of chemotherapy with cisplatin 75 mg/m(2) before he died as a result of hemorrhagic complications and progressive disease. Metastasis of BCC is a very rare condition that should not be overlooked. The prognosis remains very poor. We emphasize the importance of long-term follow-up of such patients.

    Stress fractures result from an unusual repetitive physical activity causing absorption of bone in excess of repair and bone formation. This leads to the weakening of the bone and subsequently to a fracture. It is a benign condition that if recognized in time does not need any treatment besides rest. However, if diagnosis is not made and physical activity continues it may result in severe injury to the bone and a frank fracture may result. Pain is the typical clinical feature and bone scintigraphy, being more sensitive than radiography, is done to establish early diagnosis. The presence of asymptomatic sites of abnormal bone uptake typical of stress fracture in which pain appeared only about 2 weeks after scintigraphy, drew the authors' attention to the question of how close is the relationship between stress fractures and bone pain. Sixty-four military recruits diagnosed as suffering from stress fracture were investigated in order to correlate sites with abnormal uptake of Tc-99m MDP on bone scintigraphy with sites of local pain. In 37 (58%) subjects multiple sites of abnormal uptake were recognised. Of 123 sites of abnormal uptake, 31 (25%) were asymptomatic. In three patients bone pain appeared at the site of the abnormal uptake two weeks after scintigraphy. Bone scintigraphy appears to be more sensitive than bone pain in the diagnosis of stress fractures. The osteoblastic activity which manifests itself by abnormal uptake appears in some cases earlier than the pain caused by the fracture. Present findings may suggest that under certain circumstances, in a population prone to stress fracture, bone scan should be considered as a screening method

    Bone is one of the most common metastasis sites from solid tumors. Bone pain due to metastatic neoplastic growth is due to tumor infiltration and expansion of bone membranes. Treatment of acute and chronic pain represents one of the greatest problems in clinical oncology, requiring a multidisciplinary approach. This review focuses on the effectiveness of conventional diagnostic radiology and nuclear medicine for the detection, management and treatment of pain from bone metastasis.

    Ga-67 scintigrams in patients with malignant diseases sometimes reveal uptake of the tracer in the bone metastases. Detectability of Ga-67 scintigraphy for metastatic bone tumors and benign bone lesions was compared with that of Tc-99m bone scintigraphy. Countable bone metastases detected by bone scintigraphy were evaluated whether the lesion showed apparent, faint, or negative Ga-67 uptake. Of 47 lesions 23 (49%) showed apparent uptake and 17 (36%) showed negative uptake, only 7 (10%) mostly fracture/osteotomy, showed apparent uptake of the tracer. Uptake in the other benign lesions such as trauma of the ribs, spondylosis deformans, and arthrosis deformans was rather faint. In patients with multiple bone metastases, 9 patients (82%) out of 11 showed more prominent abnormal findings in Tc-99m MDP bone scintigraphy than in Ga-67 scintigraphy; that is, Ga-67 scintigraphy was not able to reveal all metastatic bone lesions. In patients with untreated or recurrent tumors, relation between Ga-67 uptake in the tumors and that in the bone metastases was evaluated. Of 7 patients with negative Ga-67 uptake in the bone metastases; that is, there seemed to be little relation between Ga-67 affinity to the primary tumors and that to the bone metastases. Mechanisms of the Ga-67 uptake in the bone metastases were discussed. Not only the tumor cells or tissues in the bone metastases but also bone mineral or osteoclasts might be the deposition sites of Ga-67.

    1987-10-01

    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 Most deaths from solid cancers occur as a result of secondary metastasis to distant sites. Bone is the most frequent metastatic site for many cancer types and can account for up to 80% of cancer-related deaths in certain tumours. The progression from a discrete solid primary tumour to devastating and painful bone metastases is a complex process involving multiple cell types and steps. There is increasing evidence that modulation of the extracellular matrix plays an important role in the lethal transition from a primary to disseminated metastatic bone tumour. This review provides an overview of the current understanding on the role of role of lysyl oxidase, the extracellular matrix and the pre-metastatic niche in bone metastasis

    The treatment of painful skeletal metastases is a common clinical problem, and the use of therapeutic radionuclides which localize at metastatic sites has been found to be an effective method for treatment of pain, especially for multiple sites for which the use of external beam irradiation is impractical. There are currently several metastatic-targeted agents radiolabeled with various therapeutic radionuclides which are in various stages of clinical investigation. Since neutron-rich radionuclides are produced in research reactors and often decay by emission of beta- particles, most radionuclides used for bone pain palliation are reactor-produced. Key examples of radionuclides produced by single neutron capture of enriched targets include rhenium-186 and samarium-153. In addition, generator systems are also of interest which provide therapeutic daughter radionuclides from the decay of reactor-produced parent radionuclides. One important example is rhenium-188, available from generators via decay of reactor-produced tungsten-188. Tin-117m is an example of a reactor-produced radionuclide which decays with the emission of low-energy conversion electrons rather than by beta- decay. Each of these agents and/or radionuclides has specific advantages and disadvantages, however, the ideal agent for bone pain palliation has not yet been identified. The goal of this paper is to briefly review the production and use of several reactor-produced radionuclides for bone pain palliation, and to discuss the role of the ORNL High Flux Isotope Reactor (HFIR) for the production of many of these radionuclides.

    153 Sm-EDTMP is currently undergoing clinical evaluation as a radiotherapeutic agent for the relief of pain associated with cancer metastatic to bone. These clinical studies have demonstrated biodistributions similar to those seen earlier in animals, namely, rapid clearance from blood, selective uptake in bone and in particular metastatic bone lesions. The radioactivity not deposited in bone is cleared through the kidneys into the urine. In this study, urine samples collected from 9 patients injected with 153 Sm-EDTMP underwent complexation analysis via Pharmacia SP-Sephadex C25 cation exchange chromatography. The results showed 96.9 ± 1.7% of the radioactivity in the urine to be present as a complex of 153 Sm. An HPLC method was developed and it was demonstrated that different complexes of 153 Sm could be separated. A non-radioactive analytical standard of the Sm-EDTMP chelate was synthesized, characterized and shown to have the same HPLC retention profile as the 153 -EDTMP drug product. HPLC analysis was performed on six urine samples and in each case a single radioactivity peak with an elution profile the same as that of a 153 Sm-EDTMP standard was observed. These results indicate that the 153 Sm-EDTMP chelate is excreted intact in the urine of patients. (Author)

    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)

    Full Text Available Abstract Introduction Prostate cancer is the second most common cancer in men and the fifth most common cancer worldwide. In the USA it is more common in African-American men than in Caucasian men. Prostate cancer frequently metastasizes to bone and the lesions appear osteoblastic on radiographs. Presentation with diffuse osteolytic bone lesions is rare. We describe an unusual presentation of metastatic prostate cancer with diffuse osteolytic bone lesions. Case presentation A 65-year-old Namibian man presented with anemia, thrombocytopenia and worsening back pains. In addition he had complaints of effort intolerance, palpitations, dysuria and mild symptoms of bladder outlet obstruction. On examination he was found to be anemic, had a swollen tender right shoulder joint and spine tenderness to percussion. On digital rectal examination he had asymmetrical enlargement of the prostate which felt nodular and hard with diffuse firmness in some parts. His prostate-specific antigen was greater than 100ng/mL and he had diffuse osteolytic lesions involving the right humerus, and all vertebral, femur and pelvic bones. His screen for multiple myeloma was negative and the prostate biopsy confirmed prostate cancer. Conclusion Prostate cancer rarely presents with diffuse osteolytic bone lesions and should be considered in the differential diagnosis when evaluating male patients with osteolytic bone lesions.

  3. Radioisotopes for the palliation of metastatic bone cancer: a systematic review.

    2005-06-01

    Strontium-89 and samarium-153 are radioisotopes that are approved in the USA and Europe for the palliation of pain from metastatic bone cancer, whereas rhenium-186 and rhenium-188 are investigational. Radioisotopes are effective in providing pain relief with response rates of between 40% and 95%. Pain relief starts 1-4 weeks after the initiation of treatment, continues for up to 18 months, and is associated with a reduction in analgesic use in many patients. Thrombocytopenia and neutropenia are the most common toxic effects, but they are generally mild and reversible. Repeat doses are effective in providing pain relief in many patients. The effectiveness of radioisotopes can be greater when they are combined with chemotherapeutic agents such as cisplatin. Some studies with 89Sr and 153Sm indicate a reduction of hot spots on bone scans in up to 70% of patients, and suggest a possible tumoricidal action. Further studies are needed to address the questions of which isotope to use, what dose and schedule to use, and which patients will respond.

  4. Disseminated breast cancer cells acquire a highly malignant and aggressive metastatic phenotype during metastatic latency in the bone.

    Carolyn G Marsden

    Full Text Available BACKGROUND: Disseminated tumor cells (DTCs in the bone marrow may exist in a dormant state for extended periods of time, maintaining the ability to proliferate upon activation, engraft at new sites, and form detectable metastases. However, understanding of the behavior and biology of dormant breast cancer cells in the bone marrow niche remains limited, as well as their potential involvement in tumor recurrence and metastasis. Therefore, the purpose of this study was to investigate the tumorigenicity and metastatic potential of dormant disseminated breast cancer cells (prior to activation in the bone marrow. METHODOLOGY/PRINCIPAL FINDINGS: Total bone marrow, isolated from mice previously injected with tumorspheres into the mammary fat pad, was injected into the mammary fat pad of NUDE mice. As a negative control, bone marrow isolated from non-injected mice was injected into the mammary fat pad of NUDE mice. The resultant tumors were analyzed by immunohistochemistry for expression of epithelial and mesenchymal markers. Mouse lungs, livers, and kidneys were analyzed by H+E staining to detect metastases. The injection of bone marrow isolated from mice previously injected with tumorspheres into the mammary fat pad, resulted in large tumor formation in the mammary fat pad 2 months post-injection. However, the injection of bone marrow isolated from non-injected mice did not result in tumor formation in the mammary fat pad. The DTC-derived tumors exhibited accelerated development of metastatic lesions within the lung, liver and kidney. The resultant tumors and the majority of metastatic lesions within the lung and liver exhibited a mesenchymal-like phenotype. CONCLUSIONS/SIGNIFICANCE: Dormant DTCs within the bone marrow are highly malignant upon injection into the mammary fat pad, with the accelerated development of metastatic lesions within the lung, liver and kidney. These results suggest the acquisition of a more aggressive phenotype of DTCs during

    Surgical treatment of metastatic fractures of long bones is mostly a palliative one. Intramedullary stabilisation without resection of metastases follows the aim of the palliative therapy concept. From 01.01.1995 to 30.08.2001 36 manifest and 4 impending long bone fractures were registered in 22 female and 16 male patients, with a mean age of 63 years. In addition, one revision was necessary due to persisting instability after humeral intramedullary bundle nailing. Pathological fractures were found in the humerus (n=11), femoral neck (n=6), per- and subtrochanteric region (n=12), femoral shaft (n=10) and tibia (n=2). Most of them were malignancies of the kidneys (n=13), bronchi (n=7) and breast (n=6). One patient with a solitary metastasis in the humerus received curative treatment by resection, open reduction and internal fixation. All other cases underwent palliative stabilisation. Metastatic lesions of the femoral neck were treated by resection and prosthetic replacement. The remaining fractures were stabilized intramedullarily without resection of metastases or use of bone cement. In 9 cases, a locking nail was implanted in the humerus, and one patient received humeral bundle nailing. In the lower extremities, we used a classic-nail or gamma-nail in 15 and a locking nail in 8 cases. Two moribund patients did not undergo surgery. No intraoperative complications occurred. 63 % of the patients with stabilisation of the leg were able to walk at the time of discharge. The mean survival time (Kaplan-Meier) of patients after palliative operation amounted to 161.5 days (95 % CI 92.7; 230.3). We found 6 postoperative complications: temporary palsy of the radial nerve (n=1), soft tissue infection (n=1), dislocation of the nail (n=2), loosening of the distal locking screw (n=1), proceeding osteolysis with high fracture risk (n=1). Intramedullary stabilisation without resection of metastases using locking nails meets the requirements of palliative therapy. This procedure

    Bone pain is a common complication for patient with bone metastases from prostate, breasts, lung and renal cancers. The systemic treatment of metastatic bone cancers can be done by using analgesic drug therapy, hormonal therapy, chemotherapy, narcotic (morphine) and radiopharmaceuticals. Samarium-153 EDTMP is one of the most widely used radiopharmaceutical for the treatment of metallics bone pain. Preparation and quality control of 186 Re-HEDP have been carried out. Radiochemical purity was analysed using paper chromatography and resulted in maximum yields more than 90 % . Complexes quite were stable for 3 days when stored at 4 o C. Rhenium-186 HEDP complex contents in the blood reach optimum activity after 5 minutes and decrease drastically at 24 hours post injection. The complex showed major renal clearance up to 41 % as perrhenate ion within 24 hours after injection, Biodistribution pattern of the injected complex in mice indicates that the accumulated optimum activity in the bone was obtained between 2 - 24 hours post injection, Sterility and pyrogenicity test indicated that the complex were sterile and pyrogen free

    Full text: Bone metastases are often multiple, presenting with multifocal bone pain. Bone pain is a common symptom in advancing malignancy and often determines the quality of life in the later stages of disease. Management of bone pain remains palliative at present. Systemic targeted treatment of metastatic sites using radiopharmaceuticals offers potential pain relief with minimal adverse effects. Acting systemically, targeted therapy using bone seeking radiopharmaceuticals are well suited to the management of disseminated cancer when repeated local treatment becomes impractical. Radiopharmaceuticals developed for treating painful bone metastases use the following radionuclides: 32 P, 89 Sr, 186 Re, 188 Re, 153 Sm, 117mSn, 177 Lu and 223 Ra. Nuclear medicine started in the Philippines in the year 1969. Majority of the procedures are mostly diagnostic. With the improved cancer survival resulting from advances in cancer management, the population of patients seeking relief of bone pain has increased. The purpose of this study is to assess the current status of radiopharmaceutical therapy for bone pain palliation in the Philippines. It also aims to determine which radiopharmaceuticals are being used for therapy and to evaluate the acceptability, efficacy, accessibility, and cost effectiveness of the therapy in the country. To date, no local study has been done on bone pain palliation therapy. This pioneer study can serve as a baseline study for future researches on the therapy. This can also promote the therapy as an effective treatment modality in the management of bone pain secondary to bone metastases. Methods: The study population included all cancer patients with bone metastasis presenting with chronic bone pain who were subjected to radiopharmaceutical therapy for bone pain palliation in the different medical centers and hospitals in the Philippines. The clinical histories of the patients were reviewed. The specific radiopharmaceutical and corresponding doses

    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

    Full Text Available Knee pain is a common reason for a patient to seek medical evaluation. Of the many causes of knee pain, malignancy is one of the least common. When malignancy is the etiology of the pain, it is usually due to a primary tumor of the osseous structures or soft tissues of the knee joint. Metastatic disease involving the knee joint is uncommon, with few cases reported in the literature. Of these reported cases, metastatic colon cancer is exceedingly rare. However, in a patient with new onset knee pain and the proper clinical history, metastatic disease should be considered as a potential explanation of symptoms. We report a case of knee pain and swelling due to metastatic colon cancer to the patella.

    Irradiation of bone metastases primarily aims at alleviating pain, preventing fracture in the short term. The higher doses and more conformal dose distribution achievable while saving healthy tissue with new irradiation techniques have induced a paradigm shift in the management of bone metastases in a growing number of clinical situations. A search of the English and French literature was conducted using the keywords: bone metastases, radiotherapy, interventional radiology, vertebroplasty, radiofrequency, chemoembolization. RESULTS-DISCUSSION: Stereotactic irradiation yields pain relief rates greater than 90% in Phase I/II and retrospective studies. IMRT (static, rotational, helical) and stereotactic irradiation yield local control rates of 75-90% at 2 years. Some situations previously evaluated as palliative are currently treated more aggressively with optimized radiation sometimes combined modality interventional radiology. A recommendation can only be made for stereotactic irradiation in vertebral oligometastases or reirradiation. In the absence of a sufficient level of evidence, the increasing use of conformal irradiation techniques can only reflect the daily practice and the patient benefit while integrating economic logic care. The impact of these aggressive approaches on survival remains to be formally demonstrated by interventional prospective studies or observatories including quality of life items and minimal 2-year follow-up.

  13. Acupuncture for Cancer-Induced Bone Pain?

    Directory of Open Access Journals (Sweden)

    Carole A. Paley

    2011-01-01

    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.

    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 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.

    The aim of this study was to investigate the additional value of single-photon emission computed tomography (SPECT) for patient staging compared to planar bone scanning in an unselected cohort of cancer patients. The study included 271 consecutive tumor patients in whom planar imaging and two-bed position SPECT of the spine and the pelvis had been performed. Retrospective image interpretation was performed independently for planar and SPECT scans. Findings were categorized as 'benign', 'equivocal', or malignant' on a lesion base, and as 'no metastatic disease', 'equivocal', or metastatic disease' on a patient base. Four hundred and forty seven lesions were detected by SPECT. Missing of lesions in planar images was rare (4.3% of all SPECT lesions). Planar findings differed from SPECT findings in 149 lesions (33.3%). Most of these 'inconsistent' lesions were rated as equivocal in the planar images but benign (14.5% of all lesions) or malignant (11.0%) by SPECT. On a patient base, 81.6% of patients with planar equivocal staging were classified as either benign (55.3%) or malignant (26.3%) by SPECT. Patients definitively staged as 'no metastatic disease' or 'metastatic disease' in planar images were staged differently by SPECT in only 3.7% of cases (up-staging in 2.6% and down-staging in 1.1%). Single-photon emission computed tomography changed a definite staging as based on planar images in less than 4% of the patients. In patients with planar equivocal staging, however, SPECT allowed a definite diagnosis in more than 80% of these cases, and, thus, should be performed routinely in patients with equivocal findings.

    Being a tertiary referral center, we encounter the highest number of oral cancer patients in India, and there is direct involvement of the jaw bone in approximately 40% of these cases. There are no large case series from the Indian subcontinent on metastatic tumors to the jaw bones. With this retrospective analysis, we intend to estimate the incidence of this rare manifestation in the jaw bones in our patients and compare it with the available literature. All patients with biopsy proven metastatic disease involving jaw bones having complete clinical data were included. Nineteen out of 10,411 oral cancer patients who reported between the years 2000 and 2005 were included. Breast and thyroid malignancies (5/19 each) were commonest in the females to metastasize to the mandible, whereas in the males, there was no predominant site that resulted in jaw bone metastasis, although mandible was commonly affected. Neuroblastoma of adrenal gland metastasized to maxilla in the age group ranging from 4 months to 16 years. maxilla was the commonest jaw bone affected in this age group. in five cases, jaw bone was found to be the first site of metastasis. There is variation in the primary site that causes metastasis to the jaw bones depending on age, sex and geographic distribution. Jaw bone metastases are rare and can be the first site of metastasis. We get approximately four cases in a year with metastatic disease manifesting in the jaw bones. Metastasis to jaw bone is associated with poor prognosis.

    Full Text Available Advanced breast cancer frequently metastasizes to bone through a multistep process involving the detachment of cells from the primary tumor, their intravasation into the bloodstream, adhesion to the endothelium and extravasation into the bone, culminating with the establishment of a vicious cycle causing extensive bone lysis. In recent years, the crosstalk between tumor cells and secondary organs microenvironment is gaining much attention, being indicated as a crucial aspect in all metastatic steps. To investigate the complex interrelation between the tumor and the microenvironment, both in vitro and in vivo models have been exploited. In vitro models have some advantages over in vivo, mainly the possibility to thoroughly dissect in controlled conditions and with only human cells the cellular and molecular mechanisms underlying the metastatic progression. In this article we will review the main results deriving from in vitro co-culture models, describing mechanisms activated in the crosstalk between breast cancer and bone cells which drive the different metastatic steps.

    Indium is generally presumed to localize in the bone marrow within the erythroid cell line. Fibrosis, inflammation, lymphoma, extended field radiation, chemotherapy, or combinations of both treatment modalities generally depress the uptake of indium by the marrow in a complex fashion. We report a case of metastatic breast carcinoma and pancytopenia in which the In-111 scan appeared qualitatively similar to a Tc-99m MDP bone scan. Findings were confirmed by bone marrow biopsy

    Full text: Radiopharmaceutical therapy may be used for the treatment of cases with painful skeletal metastases. We evaluate and want to share an experience with application and efficacy of Sm-153 EDTMP in palliative painful bone metastases therapy. Our aim was to determine the efficacy and toxicity of single-dose Sm- 153 EDTMP as a palliative treatment for painful skeletal metastases. Material and methods: we selected 18 patients (9 male, 9 female). The average age 35-65 years weight 40- 60 kg; with metastatic bone confirmed with bone scan examination. 6 with breast cancer, 5 with nasopharyngeal cancer, 5 with prostatic cancer, 2 with lung cancer were treated with 30 mCi ( 1110 MBq) Sm-153 EDTMP. All showed extensive metastatic bone disease. The patients were given intravenous injections of 30 mCi Sm-153 EDTMP, after reconditioning, hydration . We established intensity of pain, haematological parameters, scintigraphic, Karnofsky scale. Clinical assessment was performed one month later. Responses were classified in completed (good response), partial and absent taking into account symptoms and drugs reduction. The discontinuation or the reduction of analgesic drugs like opiate dosage was also considered as successful palliative results of the treatment. Result: pain relief was obtained in 16/18 patients, Sm-153 was effective in patients with reduced drug assumption. The response to Sm-153 was good in 14/18(77,7%) of the patients and partial in 3/18(16,6%) and no response in 1/18(0,5%). The application of Sm-153 in patients with painful disseminated bone metastases has a satisfactory pain alleviating effects. Sides effects were noted, decrease hemoglobin counts and white blood cell and platelets, which gradually returned to near normal after 6 weeks. Easy application and low cost and produced in own country are important factors. Conclusion: radiopharmaceutical therapy can be recommended because of the favorable palliation effect and the low cost of Sm-153, especially

    Background and Purpose: The purpose was to develop a systematic review that would address the following question: what is the role of radiopharmaceuticals in the palliation of metastatic bone pain in adults with uncomplicated, multifocal painful bone metastases whose pain is not controlled with conventional analgesic regimens? The outcomes of interest are pain response, analgesic consumption, overall survival, adverse effects and quality of life. Materials and methods: A systematic review of the English published literature was undertaken to provide evidence relevant to the above outcomes. Results: Six randomized phase III trials, two randomized phase II trials and one randomized crossover trial of strontium-89 were reviewed. A randomized phase III trial comparing strontium-89 plus cisplatin with strontium-89 plus placebo reported a significantly higher proportion of patients experiencing pain relief for a significantly longer duration with strontium-89 plus cisplatin. A randomized phase III trial comparing adjuvant strontium-89 with placebo following radiotherapy reported a higher proportion of pain-free patients with strontium-89. Patients who received strontium-89 also experienced fewer new sites of bone pain. A second, but underpowered study failed to confirm these results. In one randomized trial of strontium-89 versus radiotherapy (hemibody or local), patients treated with strontium-89 developed fewer new sites of pain. In a second trial comparing strontium-89 versus local radiotherapy, median overall survival was improved with radiotherapy, while pain response and time-to-progression were similar in the two groups. One randomized phase III trial reported no difference in pain relief between strontium-89 and placebo. Three randomized phase III trials and two randomized phase II trials investigating samarium-153 were reviewed. In a randomized phase III trial of three different doses of samarium-153, the pain responses were similar for all three doses. In a

    Understanding cancer patients' everyday pain experiences and their concomitant use of pain medication may help identify ways to improve pain management among outpatients. This study examined the between-person and within-person associations between pain intensity and analgesic use in metastatic breast cancer patients. Fifty-three women who were initiating treatment for metastatic breast cancer completed electronic diary assessments six times per day for 14 days. The likelihood of taking medication was found to depend on patients' average pain levels and on whether their pain was better or worse than usual at the time. Patients who typically experienced moderate-to-high pain were more likely to be prescribed and to take analgesics than were patients who typically experienced low pain. However, these patients tended not to vary their medication use based on within-person fluctuations in pain. In contrast, patients who typically experienced low pain tended to increase their medication use at times when their pain was higher than usual but were less likely to use medication than were patients who typically experienced higher levels of pain. Our findings provide some evidence that patients with advanced cancer tend to use their pain medications appropriately. Patients with lower pain appear to be taking medications in response to increases in pain, whereas patients whose pain is typically more intense may be relying on other cues to prompt them to take analgesic medication. Clinicians may need to be sensitive to individual differences in the factors associated with pain medication use in daily life. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    To establish normal bone marrow values of apparent diffusion coefficient (ADC) over an age range, compare them with metastatic and myelomatous involvement, to establish reproducibility and to optimise b values. The ADCs of bone marrow in 7 volunteers (mean age 29.7 years), 34 volunteers (mean age 63.3 years) and 43 patients with metastatic and myelomatous involvement (mean age 65.5 years) were measured. In 9 volunteers diffusion weighted MRI was repeated within 7 days. b values were derived to optimise contrast between normal and pathological marrow. The mean ADC of bone marrow in younger volunteers was significantly higher than that of older volunteers. The coefficient of reproducibility was 14.8%. The ADC mean of metastatic and myeloma bone disease was 1054+/-456 x 10 -6 mm 2 s -1 . An ADC threshold of 655 x 10 -6 mm 2 s -1 separated normal and abnormal marrow with a sensitivity and specificity of 90% and 93% respectively. Contrast between normal and abnormal marrow was optimal at b = 1389 smm -2 . The reproducibility of ADC measurements in bone is equivalent to published data for soft tissue with a high sensitivity and specificity for separating abnormal from age matched normal bone marrow. A b value of around 1,400 smm -2 is optimal for imaging bone marrow. (orig.)

    We examined the efficacy of Pyridinoline-cross-linked C-terminal telopeptide of type I collagen (ICTP) and C-terminal propep tide of the type I procollagen (PICP), as bone metabolic markers (BMM) that reflect the effects of radiotherapy in patients with metastatic bone tumors (MBT). One-hundred eight patients who had had malignant tumors and been suspected of developing MBT were measured for ICTP and PICP. Ninety six patients with recognized MBT and 12 patients without MBT were evaluated for the diagnostic accuracy of MBT. Out of the 96 cases, 49 received radiotherapy and were measured for ICTP and PICP before and after the treatment. The 49 cases were divided into 25 cases (Com group) that had all of the MBT irradiated and 24 cases (InCom group) that could not have all sites irradiated. Increase ratios from before to after the radiotherapy were compared between ICTP and PICP. In the 96 patients with MBT, both ICTP and PICP were observed to be significantly high. Diagnostic accuracy was 81.5% for ICTP, and 61.6% for PICP. InCom group showed an increase in ICTP by about 25% while no significant change was observed in the Com group. BMM has diagnostic significance in patients with MBT. Performing radiotherapy to every osseous lesion results in a decline or leveling-off of ICTP. (author)

    Fifteen patients with breast cancer and skeletal metastases who had bone pain refractory to opioid analgesics and who were not eligible for or had not responded to local field radiotherapy, were treated with strontium-89. All patients had received previous treatment with chemotherapy and radiotherapy for bone metastases. Severity of bone pain, sleeping pattern, mobility and dependency on analgesics were evaluated before and 4, 8 and 12 weeks after 89 Sr administration. Patients received 2 MBq/kg (118-148 MBq) of 89 Sr by i.v. injection. Pain relief and a reduction in analgesic requirements were observed in 7 of the 15 (47%) patients, with a reduction in the severity score from 34% to 71%. Duration of the response varied from 3 to 7 months. A decrease in peripheral blood cell count was observed in 11 patients: a 15%-66% reduction in white cell count and a 14%-75% reduction in platelet count were detected at 12 weeks after treatment in these patients. We conclude that 89 Sr is effective (47% response rate) for bone pain palliation in patients with bone metastases from breast cancer. Dependency on opioid analgesics may be reduced in patients with refractory bone pain. (orig.)

    Full Text Available Michael R Harrison, Terence Z Wong, Andrew J Armstrong, Daniel J GeorgeDuke Cancer Institute, Durham, NC, USABackground: Radium-223 chloride (223Ra; Alpharadin is an alpha-emitting radioisotope that targets areas of osteoblastic metastasis and is excreted by the small intestine. When compared with beta-emitters (eg, strontium-89, samarium-153, 223Ra delivers a high quantity of energy per track length with short tissue penetration.Objective: This review describes the mechanism, radiobiology, and preclinical development of 223Ra and discusses the clinical data currently available regarding its safety and efficacy profile.Methods: Data from clinical trials including abstracts were collected and reviewed using the PubMed Database, as well as the American Society of Clinical Oncology abstract database.Conclusion: Current bone-targeted therapies fall into two main categories: antiresorptive agents (eg, zoledronic acid, denosumab, which have been shown to delay skeletal-related events, and radiopharmaceuticals (eg, samarium-153, which may have a role in pain palliation. Historically, neither antiresorptive agents nor radiopharmaceuticals have shown definitive evidence of improved overall survival or other antitumor effects in metastatic castrate-resistant prostate cancer (mCRPC. Radiopharmaceuticals are limited by myelosuppresion, thrombocytopenia, and renal excretion. In a recently reported randomized Phase III trial in men with symptomatic bone-metastatic CRPC who had received or were ineligible for docetaxel chemotherapy, 223Ra treatment resulted in improved overall survival and delayed skeletal-related events. Toxicity consisted of minor gastrointestinal side effects and mild neutropenia and thrombocytopenia that were rarely severe. Pending regulatory approval, 223Ra may represent a unique and distinct option for an important subgroup of patients with mCRPC; future trials should address its use in combination or in sequence with existing and novel

    Pain palliation with bone-seeking radiopharmaceuticals is an effective treatment modality in patients with advanced metastatic bone cancer. Several studies have shown encouraging clinical results of palliative therapy using 186 Re-HEDP, with an overall reported response rate of ± 71% for painful osseous metastasize prostate and breast cancer patients. 186 Re-HEDP is a very potential isotope with numerous advantageous characteristics for this purpose. Myelosuppressive toxicity is limited and reversible, which makes repetitive treatment safe. However, individual studies are difficult to compare, and are hampered by the numerous and different methods used to assess clinical responses. Standardized clinical response assessment using the objective multi-dimensional pain evaluation model should therefore be implemented

  9. The anti-metastatic micro-environment of the bone: Importance of osteocyte Cx43 hemichannels.

    2016-08-01

    Bone metastases of tumor cells are a common and life-threatening feature of a variety of late-stage cancers, including breast cancers. However, until now, much less has been known about the intrinsic anti-metastatic properties of the bones and how these could be exploited to prevent or treat bone metastases. Very recently, native Cx43 hemichannels present in osteocytes have been identified as important anti-metastatic signaling complexes by establishing high local extracellular ATP levels. Moreover, bisphosphonate drugs, applied as adjuvant therapies in the treatment of breast cancer patients and bone diseases, are known to display anti-metastatic properties. Now, it became clear that these compounds exert their effects through osteocyte Cx43 hemichannels, thereby triggering their opening and promoting ATP release in the extracellular micro-environment. Hence, endogenous osteocyte Cx43 hemichannels emerge as important and promising therapeutic targets for the prevention of bone metastases and/or clinical treatment of bone-metastasized breast cancers.

    Bone cancer pain (BCP) remains to be a clinical challenge with limited pharmaceutical interventions. Therefore, novel therapeutic targets for the management of BCP are in desperate need. Recently, a growing body of evidence has suggested that glial cells may play a pivotal role in the pathogenesis of BCP. Areas covered: This review summarizes the recent progress in the understanding of glia in BCP and reveals the potential therapeutic targets in glia for BCP treatment. Expert opinion: Pharmacological interventions inhibiting the activation of glial cells, suppressing glia-derived proinflammatory cytokines, cell surface receptors, and the intracellular signaling pathways may be beneficial for the pain management of advanced cancer patients. However, these pharmacological interventions should not disrupt the normal function of glia cells since they play a vital supportive and protective role in the central nervous system.

    In the progressive stages of cancer, metastatic lesions in often develop in the femur. The accompanying pain and risk of fracture dramatically affect the quality of life of the patient. Radiotherapy is often administered as palliative treatment to relieve pain and restore the bone around the lesion. It is thought to affect the bone mineralization of the treated region, but the quantitative relation between radiation dose and femur remineralization remains unclear. A new framework for the longitudinal analysis of CT-scans of patients receiving radiotherapy is presented to investigate this relationship. The implemented framework is capable of automatic calibration of Hounsfield Units to calcium equivalent values and the estimation of a prediction interval per scan. Other features of the framework are temporal registration of femurs using elastix, transformation of arbitrary Regions Of Interests (ROI), and extraction of metrics for analysis. Build in Matlab, the modular approach aids easy adaptation to the pertinent questions in the explorative phase of the research. For validation purposes, an in-vitro model consisting of a human cadaver femur with a milled hole in the intertrochanteric region was used, representing a femur with a metastatic lesion. The hole was incrementally stacked with plates of PMMA bone cement with variable radiopaqueness. Using a Kolmogorov-Smirnov (KS) test, changes in density distribution due to an increase of the calcium concentration could be discriminated. In a 21 cm3 ROI, changes in 8% of the volume from 888 ± 57mg • ml-1 to 1000 ± 80mg • ml-1 could be statistically proven using the proposed framework. In conclusion, the newly developed framework proved to be a useful and flexible tool for the analysis of longitudinal CT data.

    Purpose To update, in collaboration with Cancer Care Ontario (CCO), key recommendations of the American Society of Clinical Oncology (ASCO) guideline on the role of bone-modifying agents (BMAs) in metastatic breast cancer. This focused update addressed the new data on intervals between dosing and the role of BMAs in control of bone pain. Methods A joint ASCO-CCO Update Committee conducted targeted systematic literature reviews to identify relevant studies. Results The Update Committee reviewed three phase III noninferiority trials of dosing intervals, one systematic review and meta-analysis of studies of de-escalation of BMAs, and two randomized trials of BMAs in control of pain secondary to bone metastases. Recommendations Patients with breast cancer who have evidence of bone metastases should be treated with BMAs. Options include denosumab, 120 mg subcutaneously, every 4 weeks; pamidronate, 90 mg intravenously, every 3 to 4 weeks; or zoledronic acid, 4 mg intravenously every 12 weeks or every 3 to 4 weeks. The analgesic effects of BMAs are modest, and they should not be used alone for bone pain. The Update Committee recommends that the current standard of care for supportive care and pain management-analgesia, adjunct therapies, radiotherapy, surgery, systemic anticancer therapy, and referral to supportive care and pain management-be applied. Evidence is insufficient to support the use of one BMA over another. Additional information is available at www.asco.org/breast-cancer-guidelines and www.asco.org/guidelineswiki .

  15. Metastatic testicular cancer presenting as lower back pain in a pilot.

    Lower back pain is ubiquitous in the helicopter community and testicular cancer is the most common solid organ tumor that affects approximately 1% of men ages 15 to 35. However, rarely is lower back pain caused by testicular cancer and, in an otherwise healthy male, it is generally low on the differential diagnosis. Literature review discovered the most recent case report where lower back pain was the presenting symptom for testicular cancer was in 1987. A 26-yr-old male helicopter pilot presented to clinic complaining of lower back pain for greater than 1 yr for which conservative treatment had failed. The pain was so severe he was unable to sleep and had to remove himself from the flight schedule. The patient was seen by physical therapy and a chiropractor and treated with NSAIDs and other pain medications, including narcotics. After further investigation, it was discovered that the patient's lower back pain was a result of a retroperitoneal metastatic tumor originating from his right testicle. It is important to consider that, although most aviators in their twenties have been screened for chronic illness, they are still at risk for developing cancer. In this case, the patient never complained of testicular mass or pain and even denied symptoms during review of systems questioning. Proper education regarding the importance of self-examination and reporting of abnormalities is key to early detection and intervention. The 5-yr survival for metastatic testicular cancer is greater than 95%.

  16. Molecular Mechanisms That Contribute to Bone Marrow Pain

    Full Text Available Pain associated a bony pathology puts a significant burden on individuals, society, and the health-care systems worldwide. Pathology that involves the bone marrow activates sensory nerve terminal endings of peripheral bone marrow nociceptors, and is the likely trigger for pain. This review presents our current understanding of how bone marrow nociceptors are influenced by noxious stimuli presented in pathology associated with bone marrow. A number of ion channels and receptors are emerging as important modulators of the activity of peripheral bone marrow nociceptors. Nerve growth factor (NGF sequestration has been trialed for the management of inflammatory bone pain (osteoarthritis, and there is significant evidence for interaction of NGF with bone marrow nociceptors. Activation of transient receptor potential cation channel subfamily V member 1 sensitizes bone marrow nociceptors and could contribute to increased sensitivity of patients to noxious stimuli in various bony pathologies. Acid-sensing ion channels sense changes to tissue pH in the bone marrow microenvironment and could be targeted to treat pathology that involves acidosis of the bone marrow. Piezo2 is a mechanically gated ion channel that has recently been reported to be expressed by most myelinated bone marrow nociceptors and might be a target for treatments directed against mechanically induced bone pain. These ion channels and receptors could be useful targets for the development of peripherally acting drugs to treat pain of bony origin.

    A case is presented of a scapular chondrosarcoma which showed intense uptake of Tc-99m MPD in the primary tumour and in the pleural and osseous metastases. Additionally, there was intense visualization of the malignant pleural effusion. The bone scintigraphy correctly diagnosed the extent of the involvement. This finding is unusual because chondrosarcomas in such a disseminated state are relatively rare.

  18. Endothelial Cells as Precursors for Osteoblasts in the Metastatic Prostate Cancer Bone

    Directory of Open Access Journals (Sweden)

    Ana E. Paiva

    2017-11-01

    Full Text Available Prostate cancer cells metastasize to the bones, causing ectopic bone formation, which results in fractures and pain. The cellular mechanisms underlying new bone production are unknown. In a recent study, Lin and colleagues, by using state-of-the-art techniques, including prostate cancer mouse models in combination with sophisticated in vivo lineage-tracing technologies, revealed that endothelial cells form osteoblasts induced by prostate cancer metastasis in the bone. Strikingly, genetic deletion of osteorix protein from endothelial cells affected prostate cancer–induced osteogenesis in vivo. Deciphering the osteoblasts origin in the bone microenvironment may result in the development of promising new molecular targets for prostate cancer therapy.

    2015-11-01

    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.

    The os styloideum (ninth carpal bone) is an anatomic variant that may occur as an accessory ossicle located dorsally between the capitate and trapezoid, and the bases of the second and third metacarpals. The association of dorsal wrist pain or fatigability with an os styloideum is known as carpe bossu disease. The authors describe a woman with dorsal wrist pain in whom the diagnosis of painful os styloideum (carpe bossu disease) was made using plain radiography, bone scintigraphy and tomography

  1. The role of alpha 6 integrin in prostate cancer migration and bone pain in a novel xenograft model.

    Directory of Open Access Journals (Sweden)

    Tamara E King

    Full Text Available Of the estimated 565,650 people in the U.S. who will die of cancer in 2008, almost all will have metastasis. Breast, prostate, kidney, thyroid and lung cancers metastasize to the bone. Tumor cells reside within the bone using integrin type cell adhesion receptors and elicit incapacitating bone pain and fractures. In particular, metastatic human prostate tumors express and cleave the integrin A6, a receptor for extracellular matrix components of the bone, i.e., laminin 332 and laminin 511. More than 50% of all prostate cancer patients develop severe bone pain during their remaining lifetime. One major goal is to prevent or delay cancer induced bone pain. We used a novel xenograft mouse model to directly determine if bone pain could be prevented by blocking the known cleavage of the A6 integrin adhesion receptor. Human tumor cells expressing either the wildtype or mutated A6 integrin were placed within the living bone matrix and 21 days later, integrin expression was confirmed by RT-PCR, radiographs were collected and behavioral measurements of spontaneous and evoked pain performed. All animals independent of integrin status had indistinguishable tumor burden and developed bone loss 21 days after surgery. A comparison of animals containing the wild type or mutated integrin revealed that tumor cells expressing the mutated integrin resulted in a dramatic decrease in bone loss, unicortical or bicortical fractures and a decrease in the ability of tumor cells to reach the epiphyseal plate of the bone. Further, tumor cells within the bone expressing the integrin mutation prevented cancer induced spontaneous flinching, tactile allodynia, and movement evoked pain. Preventing A6 integrin cleavage on the prostate tumor cell surface decreased the migration of tumor cells within the bone and the onset and degree of bone pain and fractures. These results suggest that strategies for blocking the cleavage of the adhesion receptors on the tumor cell surface can

    Approximately 85% of patients with cancer suffer severe metastatic bone pain for which radionuclide therapy has been employed for pain palliation. We undertook this study to evaluate the pain relief effect of (153)Sm-EDTMP in Mexican patients with severe and painful bone metastases from mainly prostate, breast, and renal cancer and other malignancies. Patients (277) with intense sustained pain caused by bone metastases were referred to the Nuclear Medicine Department of the Oncology Hospital of the Mexican Social Security Institute. The patients had to have acceptable physical conditions, a previous positive (99m)Tc-MDP scan and blood values within normal range. (153)Sm-EDTMP was prepared at the Instituto Nacional de Investigaciones Nucleares (ININ) and 37 MBq/kg of body weight was injected intravenously. Pain palliation was evaluated with a visual analogue scale (VAS) and a verbal rating scale (VRS) before treatment and 3 and 12 weeks after treatment was started. The age interval of the patients was 24-92 years with a mean age of 64 ± 12 years. Mean values for hemoglobin, leukocyte and platelet counts did not statistically differ at zero time, 3 and 12 weeks after treatment. Pain intensity and relief assessment were statistically different: 9.1 ± 0.61 units initially; 4.2 ± 1.3 units 3 weeks later (54%) and after 12 weeks the pain diminished to 2.4 ± 1.4 units (74%) in the pain relief score scales. (153)Sm-EDTMP was readily available, safe and well tolerated. We conclude that (153)Sm-EDTMP was an adequate palliative agent and was the best option for our Mexican patients to relieve their severe metastatic bone pain. Copyright © 2014 IMSS.

    Bone scanning with sup(99m)Tc sodium pyrophosphate was performed in 65 patients with primary neoplasms, using a gamma-camera. The scans are compared to those obtained with 85 Sr and 87 Sr. Sup(99m)Tc appears to be superior to the other two in the detection of metastatic bone lesions, mainly because of its physical characteristics (high yield of 140 KeV photons, short physical half-life). The advantages related to these characteristics are emphasized: possibility of rapid and systematic investigation of the whole skeleton using a gamma-camera; low dose irradiation of the patient which enables frequent repetitive studies to be performed [fr

Materials and methods: From 2010 to 2013, 245,707 breast cancer patients and 8901 patients diagnosed with initial bone metastasis were identified by Surveillance, Epidemiology, and End Results database of the National Cancer Institute. Multivariate logistic and Cox regression were used to identify predictive factors for the presence of bone metastasis and prognosis factors. Kaplan–Meier method and log-rank test were used for survival analysis. Results: Eight thousand nine hundred one patients with initial MBC had bone involvement, accounting for 3.6% of the entire cohort and 62.5% of the patients with initial MBC. Also, 70.5% of patients with bone metastasis were hormone receptor (HR positive (HR+/human epidermal growth factor receptor 2 [HER2]−: 57.6%; HR+/HER2+: 12.9%. Patients with initial bone metastasis had a better 5-year survival rate compared to those with initial brain, liver, or lung metastasis. HR+/HER2− and HR+/HER2+ breast cancer had a propensity of bone metastasis in the entire cohort and were correlated with better prognosis in patients with initial bone metastasis. Local surgery had significantly improved overall survival in initial MBC patients with bone metastasis. Conclusion: Our study has provided population-based estimates of epidemiologic characteristics and prognosis in patients with bone metastasis at the time of

    Eight out of 10 breast cancer patients die within 5 years after the primary tumor has spread to the bones. Tumor cells disseminated from the breast roam the vasculature, colonizing perivascular niches around blood capillaries. Slow flows support the niche maintenance by driving the oxygen, nutrients, and signaling factors from the blood into the interstitial tissue, while extracellular matrix, endothelial cells, and mesenchymal stem cells regulate metastatic homing. Here, we show the feasibility of developing a perfused bone perivascular niche-on-a-chip to investigate the progression and drug resistance of breast cancer cells colonizing the bone. The model is a functional human triculture with stable vascular networks within a 3D native bone matrix cultured on a microfluidic chip. Providing the niche-on-a-chip with controlled flow velocities, shear stresses, and oxygen gradients, we established a long-lasting, self-assembled vascular network without supplementation of angiogenic factors. We further show that human bone marrow-derived mesenchymal stem cells, which have undergone phenotypical transition toward perivascular cell lineages, support the formation of capillary-like structures lining the vascular lumen. Finally, breast cancer cells exposed to interstitial flow within the bone perivascular niche-on-a-chip persist in a slow-proliferative state associated with increased drug resistance. We propose that the bone perivascular niche-on-a-chip with interstitial flow promotes the formation of stable vasculature and mediates cancer cell colonization.

    Percutaneous vertebroplasty comprises the injection of Polymethylmethacrylate (PMMA) bone cement into vertebrae and can be used for the treatment of compression fractures of vertebrae. Metastatic bone tumors can cause such compression fractures but are not treated when injecting PMMA-based bone cement. Hyperthermia of tumors can on the other hand be attained by placing magnetic nanoparticles (MNPs) in an alternating magnetic field (AMF). Loading the PMMA-based bone cement with MNPs could both serve vertebra stabilization and metastatic bone tumor hyperthermia when subjecting this PMMA-MNP to an AMF. A dedicated pancake coil is designed with a self-inductance of 10 μH in series with a capacitance of 0.1 μF that acts as resonant inductor-capacitor circuit to generate the AMF. The thermal rise is appraised in beef vertebra placed at 10 cm from the AMF generating circuit using optical temperatures sensors, i.e. in the center of the PMMA-MNP bone cement, which is located in the vicinity of metastatic bone tumors in clinical applications; and in the spine, which needs to be safeguarded to high temperature exposures. Results show a temperature rise of about 7 °C in PMMA-MNP whereas the temperature rise in the spine remains limited to 1 °C. Moreover, multicycles heating of PMMA-MNP is experimentally verified, validating the technical feasibility of having PMMA-MNP as basic component for percutaneous vertebroplasty combined with hyperthermia treatment of metastatic bone tumors.

    While basal cell carcinoma (BCC) remains the most common skin cancer, the incidence of metastasis is rare. Most cases of metastatic BCC have been to regional lymph nodes. Metastasis to bone marrow with myelophthisic anemia is especially rare. To our knowledge, there have been only 5 reported cases in literature. We report a sixth case. A 46-year-old male patient presented with an 8 × 7-cm ulcerated plaque on his chest, found to be morpheaform basal cell on pathology. Laboratory findings were notable for normocytic anemia, thrombocytopenia, and elevated LDH. Further work up with bone marrow biopsy revealed tumor cells staining positive for CK AE1/AE3, BerEP4, CK7, CD56, and PIN-4. This confirmed the diagnosis of metastatic BCC (MBCC) to bone marrow. Although the rate of metastasis for BCC is rare, once it occurs, prognosis is poor. MBCC remains a challenge to treat. Therefore, it is critical to resolve the primary BCC and obtain vigilant follow-up, especially in patients with multiple risk factors for MBCC.

    Background: The optimum dose and fractionation schedule for the palliative irradiation of painful bone metastases is controversial. Purpose: To compare the efficacy, side-effects and effect on quality of life of two commonly used radiotherapy schedules in the management of painful bone metastases. Materials and methods: In a prospective trial, 280 patients were randomised to receive either a single 10 Gy treatment or a course of 22.5 Gy in five daily fractions for the relief of localised metastatic bone pain. Results: Response rates have been calculated from 240 assessable treated sites of pain. The overall response rates were 83.7% (single treatment) and 89.2% (five fractions). The complete response rates were 38.8% (single treatment) and 42.3% (five fractions). The median duration of pain control was 13.5 weeks (single treatment) and 14.0 weeks (five fractions). None of these differences was statistically significant. There were no differences between the groups in the effect of treatment on a variety of quality of life parameters. Conclusions: It is concluded that a single 10 Gy treatment is as effective as a course of 22.5 Gy in five fractions in the management of painful bone metastases

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.

    Full text: In patients with osteoarthritis bone scintigraphy is consistently reported as demonstrating mild, moderate or severe arthritis, particularly for the medial compartment of the knee, depending on the degree of uptake. Numerous studies however have not demonstrated a correlation between severity of bone scan findings and severity of osteoarthritis (OA) demonstrated at surgery or arthroscopy. In fact, most studies have not demonstrated any correlation between OA as assessed with imaging and subsequent surgical findings. The only positive correlation for outcome of OA of the knee appears to be the severity of pain. In this pilot study we investigate if there is correlation between pain and scintigraphic findings in medial compartment OA. 69 patients (18 - 87 years) without history of recent knee trauma or previous surgery for insertion of knee prosthesis who presented for a bone scan for any reasons were studied. All patients were asked to quantify any knee pain on a simple 4 point score i.e. no pain, non limiting pain, pain limiting daily activity and rest pain. Uptake in the medial compartment of the knee was quantified by measuring the count ratio between the medial compartment and the corresponding distal femur. 45 patients reported no pain, 20 reported non-limiting pain while 4 reported limiting pain. No patient reported pain at rest. In general pain was bilateral with no major differences. The mean knee/femur ratio for patients with no pain was 1.46 +/- 0.95 (N=90). Knee/femur ratio for patients with non-limiting pain was 1.77 +/- 0.57 (N=40) and for those with limiting pain it was 2.36 +/- 1.82 (N=8). Although the results were not statistically significant there was a clear trend towards a rising knee/femur ratio with increasing pain. The number of patients with knee pain was small and further study concentrating on this group would be required to assess the significance of the trend findings. Further study particularly in patients with significant

    Full Text Available Abstract Background Giant cell tumour of bone (GCTB is an expansile osteolytic tumour which contains numerous osteoclast-like giant cells. GCTB frequently recurs and can produce metastatic lesions in the lungs. Bisphosphonates are anti-resorptive drugs which act mainly on osteoclasts. Method In this study, we have examined clinical and radiological outcomes of treatment with aminobisphosphonates on 25 cases of aggressive primary, recurrent and metastatic GCTB derived from four European centres. We also analysed in vitro the inhibitory effect of zoledronic acid on osteoclasts isolated from GCTBs. Results Treatment protocols differed with several different aminobisphosphonates being employed, but stabilisation of disease was achieved in most of these cases which were refractory to conventional treatment. Most inoperable sacral/pelvic tumours did not increase in size and no further recurrence was seen in GCTBs that had repeatedly recurred in bone and soft tissues. Lung metastases did not increase in size or number following treatment. Zoledronic acid markedly inhibited lacunar resorption by GCTB-derived osteoclasts in vitro. Conclusion Our findings suggest that bisphosphonates may be useful in controlling disease progression in GCTB and that these agents directly inhibit GCTB - derived osteoclast resorption. These studies highlight the need for the establishment of standardised protocols to assess the efficacy of bisphosphonate treatment of GCTB.

    An 80-year-old man visited our clinic with the chief complaint of asymptomatic macroscopic hematuria secondary to anticoagulant medicine. Although digital rectal examination was normal, a high serum prostate specific antigen (PSA) level (85.9 ng/ml) led us to perform sextant prostate biopsy, resulting in negative for cancer. Three months later, since the serum PSA increased to 169 ng/ml with high serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 levels. Twelve-core prostate biopsy was performed again, but the result was negative. Pelvic magnetic resonance imaging (MRI) showed a metastatic lesion on the right pubic bone, which was biopsied, and turned out to be poorly differentiated prostate cancer in histology. Maximum androgen blockade failed to control PSA. Finally he died of pneumonia 55 days after the bone biopsy. To our knowledge, there were only two case reports diagnosed as prostate cancer by biopsies of the metastatic lesions in Japanese literature, but none in the English literature. These findings suggest that high serum levels of CEA and CA19-9 in patients with prostate cancer are indications of hormone-refractory prostate cancer resulting in poor prognosis.

    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.

    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. Copyright © 2015 Elsevier Inc. All rights reserved.

    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.

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

    Temporomandibular (TM) joint pain results from many etiologic factors. The aim of this study was to evaluate the utility of Bone SPECT in patients with TM joint pain. The subjects were 34 patients with TM joint pain. All patients underwent plain radiography, planar bone scan, and Bone SPECT. The intensity of radioisotope uptake at TM joint was graded into three; no increased uptake above the background activity as grade 0, uptake similar to occipital bone as grade I, and uptake similar to maxillary sinus as grade II. Clinical findings and therapeutic methods were reviewed. Twenty-seven patients (80%) out of 34 patients with TM joint pain had increased uptake in bone SPECT. Twenty-one (78%) out of 27 patients had increased uptake in the mandibular condyle and remaining six patients (22%) had uptake in the mandibular and maxillary arch, which proved to be dental problem. Seven patients (21%) out of 34 were grade as 0, four (12%) were grade I, 23 (68%) were grade. II. Four patients with grade I had clicking sound and symptoms which were subsided with medication in all cases. Among 23 patients with grade II, 7 patients had clicking sound and 14 patients underwent medication and decompression therapy. With Planar bone scan, 11 cases (32%) had increased uptake in TM joint area. Plain radiography revealed narrowing, distension, erosion and limitation of TM joint in 16 cases (47%). Bone SPECT can be valuable for screening and managing the patients with TM joint pain. Patients with grade II needed intensive treatment such as joint aspiration. However degree of the radioisotope uptake did not well correlated with clinical symptoms

    It has been reported that MRgFUS has pain palliative effects on the local pain in patients with bone metastasis. In general, a severity of pain has been evaluated using only subjective method with numerical rating scale (NRS) or visual analogue scale (VAS). It is important to evaluate local pain-palliative effects of MRgFUS treatment with objective and quantitative method. The aim of this study is to investigate changes in the severity of local pain of bone metastasis before and after MRgFUS treatments, measuring pressure pain threshold (PPT) using pressure algometer, and pain intensity using electrical stimulation device (the Pain Vision system) at most painful site of bone metastasis. We have conducted MRgFUS for pain palliation of bone metastasis for 8 patients, and evaluated the local tenderness quantitatively for 8 patients, and evaluated local pain intensity for 7 patients. Before the treatments, PPTs were 106.3kPa [40.0-431.5] at metastatic site and 344.8 kPa [206.0-667.0] at normal control site, which showed a significant difference. The PPTs at metastatic site shows a significant increase from 106.3 kPa [40.0-431.5] at the baseline to 270.5 kPa [93.5-533.5] at 3 months after the treatment. The NRS score shows a significant decrease from 6.0 [4-8] at baseline to 1 [0-3] at 3 months after the treatment. Similarly, the pain intensity shows a significant decrease 245 [96.3-888.7] at baseline to 55.9 [2.8-292] at 3 months after the treatment. The results of our study illustrate the pain-relieving effects of MRgFUS for the treatment of painful bone metastasis. PPT might be a useful parameter not only for assessing a treatment's effect, but also for the decision of the painful area to treat with MRgFUS. Pain Vision seems to be useful for quantitative and objective evaluation of local pain of painful bone metastasis.

    Full Text Available Percutaneous vertebroplasty comprises the injection of Polymethylmethacrylate (PMMA bone cement into vertebrae and can be used for the treatment of compression fractures of vertebrae. Metastatic bone tumors can cause such compression fractures but are not treated when injecting PMMA-based bone cement. Hyperthermia of tumors can on the other hand be attained by placing magnetic nanoparticles (MNPs in an alternating magnetic field (AMF. Loading the PMMA-based bone cement with MNPs could both serve vertebra stabilization and metastatic bone tumor hyperthermia when subjecting this PMMA-MNP to an AMF. A dedicated pancake coil is designed with a self-inductance of 10 μH in series with a capacitance of 0.1 μF that acts as resonant inductor-capacitor circuit to generate the AMF. The thermal rise is appraised in beef vertebra placed at 10 cm from the AMF generating circuit using optical temperatures sensors, i.e. in the center of the PMMA-MNP bone cement, which is located in the vicinity of metastatic bone tumors in clinical applications; and in the spine, which needs to be safeguarded to high temperature exposures. Results show a temperature rise of about 7 °C in PMMA-MNP whereas the temperature rise in the spine remains limited to 1 °C. Moreover, multicycles heating of PMMA-MNP is experimentally verified, validating the technical feasibility of having PMMA-MNP as basic component for percutaneous vertebroplasty combined with hyperthermia treatment of metastatic bone tumors.

    Full text: Introduction: Bone metastases are the most common cause of pain in patients with cancer, and postmortem studies have been shown that up to 85% of patients with breast or prostate cancer have bone metastases at the time of death. The palliation of bone pain is one of the goals of treatments in oncologic patients, due to the fact that patients with bone metastases may survive many years with severe pain and seriously impaired mobility. Bone pain palliation can be attempted by using different modalities analgesics (nonsteroid, opioides), biphosphonates, external beam radiotherapy or radionuclide therapy. Purpose The aim of our study was to review the database and to analyze the results of the treatments performed in our department, in the field of radionuclide metastatic bone pain palliation with 89 Sr Method: 12 patients (47-73 years old) were treated with 89 Sr in the past two years in our department. All patients had confirmed prostate adenocarcinoma and refractory bone pain due to skeletal metastasis involving more than one site, associated with osteoblastic response on bone scan. All patients had a good hematological and renal status (Hb> 9 mg/dl, leukocytes > 4000/ μl, platelets > 150.000/ μl, GFR > 30 ml/min), an increased alkaline phosphatase and recent bisphosphonate therapy interrupted within 48h before treatment. The standard administered dose was 150 MBq [4 mCi] of 89 Sr (Metastron Amersham). In 8 cases single dose was given, while in 4 patients a second dose was administered at 4, 6 or 9 months after the first injection. Clinical and biological evaluation was repeated at 3 weeks and 3-6 months after treatment. Hematological assessment was performed monthly for all patients. Results The most important criterion of pain relief was objective pain score. Significant improvement of life quality was seen in 4 patients with major reduction of analgesic needs. In 4 patients in addition to external beam radiotherapy we obtained a stable effect of more

    This paper summarizes radiation therapy in the treatment of bone metastases from breast cancer. 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.

    Percutaneous vertebroplasty (PVP) is a minimally invasive outpatient procedure whereby vertebral compression fractures are stabilized by the injection of bone cement, or polymethyl methacrylate (PMMA). Rapid partial or complete pain relief can usually be achieved through this procedure. We prospectively evaluate the efficacy of PVP in the relief of pain and improvement in quality of life of patients with intractable pain from osteoporotic and metastatic fractures. Patients with intractable pain from vertebral metastases (many resistant to palliative radiation therapy) and patients with intractable painful osteoporotic fractures were treated with parapedicular or transpedicular injection of PMMA. Plane X-rays, computed tomography (CT) scan, and magnetic resonance imaging (MRI) scan were performed on all patients. With a reflex hammer, percussion pain was correlated to the imaging abnormalities. The preplanning CT scan was used to calculate the exact entry point and angle of the bone-biopsy needle. All patients were assessed before and after the procedure for quality of life and amount of pain. The following measures were used: 1) the Edmonton Symptom Assessment System (ESAS), for global pain, nausea, tiredness, depression, anxiety, drowsiness, appetite, sense of well-being, and shortness of breath; 2) a site-specific pain score (SSPS); 3) the amount of analgesic intake in morphine equivalents in the last 24 hours; and 4) the Townsend Functional Assessment Scale (TFAS), ascertaining mobility. A postprocedural CT scan was performed the same day on all patients. Follow-up assessment consisted of a phone call at Days 1, 2, and 4 and Weeks 1, 2, 4, 8, and 12. Patients with recurrent back pain or complications were followed in the bone metastases clinic. Thirty patients (19 women, 11 men) were evaluated. Their median age was 68 years (range 31 to 87 years). Thirty procedures (n=30) at 45 vertebral levels were performed; 13 were for pathologic fractures, and 17 were for

    Bisphosphonates offer a significant improvement in the quality of life for cancer patients; these potent inhibitors of bone resorption have been shown to markedly reduce the morbidity frequently resulting from bone metastases. Despite the success of bisphosphonates as therapeutic agents, however, toxicity in the form of osteonecrosis of the jaw (ONJ) is a rare complication whose incidence rate has climbed in recent years. ONJ is defined as an unexpected development of necrotic bone in the oral cavity, and is commonly associated with administration of the bisphosphonates Pamidronate and Zoledronate. Clinical features include local pain, soft-tissue swelling, and/or loose teeth; ONJ is also often correlated with previous dental procedures, such as tooth extractions, during biphosphonate therapy. Although additional risk factors-such as corticosteroids, chemotherapy, radiotherapy, trauma or infection-exhibit etiological associations with ONJ, the real pathobiology has not yet been fully elucidated. Here we report our findings on all 2005 OJN cases presented at our institution resulting from bone metastatic prostate cancer treated with zoledronic acid. The incidence of ONJ is nearly 3% (3 out of 104) in these patients.

Renal failure was induced in 8-week-old male Wistar rats by feeding 0.75% adenine-containing diet for 6 weeks. Serum parameters, parathyroid hyperplasia, bone changes and metastatic calcification were examined at 2, 4 and 6 weeks. Progressive increase of serum creatinine and inorganic phosphate, and decreased levels of serum calcium and 1,25(OH)2D3 were confirmed. Markedly enlarged parathyroid glands and extremely high PTH levels were observed in all adenine-fed rats compared with the control (PTH: 199.3+/-58.0 vs 10.5+/-3.0 pmol/l, Prats. Uraemic rats made by adenine diet developed severe abnormalities of calcium metabolism in a relatively short period and therefore they may serve as a useful model for the analysis of parathyroid hyperplasia and vascular calcification in chronic renal failure.

    Accurate skeleton registration is necessary to match corresponding metastatic bone lesions for response assessment over multiple scans. In articulated registration (ART), whole-body skeletons are registered by auto-segmenting individual bones, then rigidly aligning them. Performance and robustness of the ART in lesion matching were evaluated and compared to other commonly used registration techniques. Sixteen prostate cancer patients were treated either with molecular targeted therapy or chemotherapy. Ten out of the 16 patients underwent the double baseline whole-body [F-18]NaF PET/CT scans for test-retest (TRT) evaluation. Twelve of the 16 patients underwent pre- and mid-treatment [F-18]NaF PET/CT scans. Skeletons at different time points were registered using ART, rigid, and deformable (DR) registration algorithms. The corresponding lesions were contoured and identified on successive PET images based on including the voxels with the standardized uptake value over 15. Each algorithm was evaluated for its ability to accurately align corresponding lesions via skeleton registration. A lesion matching score (MS) was measured for each lesion, which quantified the per cent overlap between the lesion's two corresponding contours. Three separate sensitivity studies were conducted to investigate the robustness of ART in matching: sensitivity of lesion matching to various contouring threshold levels, effects of imperfections in the bone auto-segmentation and sensitivity of mis-registration. The performance of ART (MS = 82% for both datasets, p ≪ 0.001) in lesion matching was significantly better than rigid (MS TRT  = 53%, MS Response  = 46%) and DR (MS TRT  = 46%, MS Response  = 45%) algorithms. Neither varying threshold levels for lesion contouring nor imperfect bone segmentation had significant (p∼0.10) impact on the ART matching performance as the MS remained unchanged. Despite the mis-registration reduced MS for ART, as low as 67% (p ≪ 0.001), the

    This is an updated version of the original Cochrane review published in Issue 3 (Lee 2012) on patient positioning (mobilisation) and bracing for pain relief and spinal stability in adults with metastatic spinal cord compression.Many patients with metastatic spinal cord compression (MSCC) have spinal instability, but their clinician has determined that due to their advanced disease they are unsuitable for surgical internal fixation. Mobilising may be hazardous in the presence of spinal instability as further vertebral collapse can occur. Current guidance on positioning (whether a patient should be managed with bed rest or allowed to mobilise) and whether spinal bracing is helpful, is contradictory. To investigate the correct positioning and examine the effects of spinal bracing to relieve pain or to prevent further vertebral collapse in patients with MSCC. For this update, we searched for relevant studies from February 2012 to 31 March 2015. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In Process, EMBASE, AMED, CINAHL, TRIP, SIGN, NICE, UK Clinical Research Network, National Guideline Clearinghouse and PEDro database. We also searched the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov, UK Clinical Trials Gateway (UKCTG), WHO International Clinical Trials Registry Platform (ICTRP) and Australia New Zealand Clinical Trials Registry (ANZCTR).For the original version, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, CANCERLIT, NICE, SIGN, AMED, TRIP, National Guideline Clearinghouse, and PEDro database, in February 2012. We selected randomised controlled trials (RCTs) of adults with MSCC of interventions on positioning (mobilisation) and bracing. Two review authors independently assessed each possible study for inclusion and quality. For the original version of the review, we screened 1611 potentially relevant studies.

    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.

    Men who receive bone-targeted therapy for metastatic prostate cancer are at increased risk of osteonecrosis of the jaw (ONJ). Development of ONJ has been associated with the administration of bone-targeted therapies in association with other risk factors. ONJ can be distressing for a patient because it can cause pain, risk of jaw fracture, body image disturbance, difficultly eating, and difficulty maintaining good oral hygiene. The aim of this article is to report results of an audit of prior assessment by oral and maxillofacial surgeons (OMFS) before initiation of bone-targeted therapies and whether it may reduce the risk of ONJ in patients receiving bone-targeted therapies for advanced cancers.

    Despite affecting millions of people, chronic pain is generally treated insufficiently. A major point of focus has been the lack of translation from preclinical data to clinical results, with the predictive value of chronic pain models being a major concern. In contrast to current focus on stimulus......-based nociceptive responses in preclinical research, development of behavioural tests designed to quantify suspension of normal behaviour is likely a more equivalent readout for human pain-assessment tests. In this study, we quantified grid-climbing behaviour as a non-stimulus-evoked behavioural test for potential...... use as a measure of neuropathic and cancer-induced bone pain in mice. In both models, the grid-climbing test demonstrated pain-related sparing of the affected leg during climbing. In both models, the behaviour was reversed by administration of morphine, suggesting that the observed behaviour was pain-specific....

    Background: External beam radiotherapy is frequently applied for palliative treatment of painful bone lesions with a variety of fractionation schemes. There is a continuous interest to administer only 1 or a few dose fractions for inducing pain relief. Methods: A review of the literature was made with the aim to determine whether a treatment can be deduced that is simple and effective. The linear-quadratic (L-Q) concept was applied to compare reported therapy schemes which each other for the iso-effect pain relief. Results: Single-dose and fractionated radiotherapy resulted in partial or complete pain relief in about 80% of the patients. Complete responses have been observed in about 43% of the patients. For patients responding to treatment, the duration of pain relief is at least 3 to 4 months with reported duration of up to 1 year or even longer. Conclusion: Based on this review of literature data concerning randomized trials a treatment with a single dose of 8 Gy is effective for inducing pain relief. (orig.) [de

    Abstract Recently, an inverse role for Wnt signaling in the development of osteoclasts in the bone was demonstrated. In the present study, we examined whether there is a commonality in the mechanism of bone resorption and lysis that occur in a diverse set of bone metastatic lesions, as well as in primary bone lesions. Compared with control bone tissue and bone biopsies from patients with nonmetastatic primary tumors (i.e., breast carcinoma, lung adenocarcinoma, and prostate carcinoma), patients with bone metastatic lesions from the three aforementioned primary tumors, as well as osteolytic lesions obtained from the bone biopsies of patients with multiple myeloma, demonstrated an upregulated expression of the glycoprotein Dickkopf-1 at both the mRNA and protein levels. Additionally, by coimmunoprecipitation, Dickkopf-1 pulled-down low-density lipoprotein receptor-related protein 6 (Lrp6), which is a key downstream effector of the Wnt signaling pathway. The expression of Lrp6 was unaltered in the osteometastatic lesions. This negative regulation was associated with a lowered expression of osteoprotegerin in the osteometastatic lesions, an observation that was previously reported to promote osteoclastogenesis. These findings provide a common mechanism for the inverse relationship between the Wnt signaling pathway and the development of primary or metastatic bone lesions. Pharmacological modulation of the Wnt signaling pathway might benefit the clinical management of primary and metastatic bone lesions. PMID:27310953

  5. Interleukin-6: a bone marrow stromal cell paracrine signal that induces neuroendocrine differentiation and modulates autophagy in bone metastatic PCa cells.

    Autophagy reallocates nutrients and clears normal cells of damaged proteins and organelles. In the context of metastatic disease, invading cancer cells hijack autophagic processes to survive and adapt in the host microenvironment. We sought to understand how autophagy is regulated in the metastatic niche for prostate cancer (PCa) cells where bone marrow stromal cell (BMSC) paracrine signaling induces PCa neuroendocrine differentiation (NED). In PCa, this transdifferentiation of metastatic PCa cells to neuronal-like cells correlates with advanced disease. Because autophagy provides a survival advantage for cancer cells and promotes cell differentiation, we hypothesized that autophagy mediates PCa NED in the bone. Thus, we determined the ability of paracrine factors in conditioned media (CM) from two separate BMSC subtypes, HS5 and HS27a, to induce autophagy in C4-2 and C4-2B bone metastatic PCa cells by characterizing the autophagy marker, LC3. Unlike HS27a CM, HS5 CM induced LC3 accumulation in PCa cells, suggesting autophagy was induced and indicating that HS5 and HS27a secrete a different milieu of paracrine factors that influence PCa autophagy. We identified interleukin-6 (IL-6), a cytokine more highly expressed in HS5 cells than in HS27a cells, as a paracrine factor that regulates PCa autophagy. Pharmacological inhibition of STAT3 activity did not attenuate LC3 accumulation, implying that IL-6 regulates NED and autophagy through different pathways. Finally, chloroquine inhibition of autophagic flux blocked PCa NED; hence autophagic flux maintains NED. Our studies imply that autophagy is cytoprotective for PCa cells in the bone, thus targeting autophagy is a potential therapeutic strategy.

    Full Text Available The aim of the study was to assess health-related quality of life (HRQoL among metastatic soft tissue (mSTS or bone sarcoma (mBS patients who had attained a favourable response to chemotherapy. We employed the EORTC QLQ-C30, the 3-item Cancer-Related Symptoms Questionnaire, and the EQ-5D instrument. HRQoL was evaluated overall and by health state in 120 mSTS/mBS patients enrolled in the SABINE study across nine countries in Europe and North America. Utility was estimated from responses to the EQ-5D instrument using UK population-based weights. The mean EQ-5D utility score was 0.69 for the pooled patient sample with little variation across health states. However, patients with progressive disease reported a clinically significant lower utility (0.56. Among disease symptoms, pain and respiratory symptoms are common. This study showed that mSTS/mBS is associated with reduced HRQoL and utility among patients with metastatic disease.

    Prediction of survival in patients having surgery for metastatic bone disease in the extremities (MBDex) has been of interest in more than two decades. Hitherto no consensus on the value of biochemical variables has been achieved. Our purpose was (1) to investigate if standard biochemical variables have independent prognostic value for survival after surgery for MBDex and (2) to identify optimal prognostic cut off values for survival of biochemical variables. In a consecutive cohort of 270 patients having surgery for MBDex, we measured preoperative biochemical variables: hemoglobin, alkaline phosphatase, C-reactive protein and absolute, neutrophil and lymphocyte count. ROC curve analyses were performed to identify optimal cut off levels. Independent prognostic factors for variables were addressed with multiple Cox regression analyses. Optimal cut off levels were identified as: hemoglobin 7.45 mmol/L, absolute lymphocyte count 8.5 × 10 9 /L, neutrophil 5.68 × 10 9 /L, lymphocyte 1.37 × 10 9 /L, C-reactive protein 22.5 mg/L, and alkaline phosphatase 129 U/L. Regression analyses found alkaline phosphatase (HR 2.49) and neutrophil count (HR 2.49) to be independent prognostic factors. We found neutrophil count and alkaline phosphatase to be independent prognostic variables in predicting survival in patients after surgery for MBDex. © 2016 Wiley Periodicals, Inc.

    Defining an optimal imaging modality for assessment of therapy and the best time of evaluation are pivotal for ideal patient's management. {sup 223}Ra (Xofigo registered, formerly Alpharadin) has been approved by the FDA and European Medicines Agency for treatment of metastatic castration-resistant prostate cancer with painful osseous involvement. PET/CT imaging using various radiotracers such as {sup 18}F-FDG, {sup 18}F-FCH, {sup 68}Ga-PSMA and {sup 18}F-NaF have been investigated to mitigate the limitations of conventional imaging modalities. Diagnostic radiotracers that have properties similar to a therapeutic radiotracer will precisely assess of the possibility and efficacy of a treatment; this is the theranostic concept. An example of a diagnostic test employed for selecting targeted therapy is the combined use of {sup 18}F-fluoride PET/CT for evaluation of possible therapy with {sup 223}Ra. This review examines the most recent publications related to this topic. (orig.)

    Knee pain is one of the common complaints of patients seen in our orthopedic clinic. Routine anterior and posterior views of whole body bone scan (WBBS) is often not sufficient in the evaluation of these patients. An ideal bone scan using pinhole collimator or single photon emission tomography (SPECT), however, is impractical and time consuming in busy nuclear medicine department with limited resources. Therefore, the aim of the study is to assess limited bone scan of knees with magnification (LNSKM) for knee pain evaluation. Technical aspect of LBSKM and diagnostic efficacy are discussed on this poster. Adult patients with knee pain were reffered for LBSKM from an orthopedic surgen specializing knees. Four hundred fifteen LBSKMs were performed since 1999. patients were given 740 MBq (20mCi) Tc-99m MDP intravenously and 3 hours later LBSKM was performed using a low energy high resolution parallel hole collimator and Siemens Orbitor camera. (Simens medical systems. Inc., Hoffman Estates, III., USA). Anterior view of the knees was taken for 5 min, without magnification and both lateral views of symptomatic knees were obtained with electronic magnification (1.25, upto 2.0) for 8 min each. Disease processes such as DJD, traumatic arthritis, P-F tendonitis, SONK, meniscus tear are detected and illustrated along with normal knee scan finding. We believe LBSKM may not be as good as SPECT or pinhole imaging of the knees in the evaluation of knee pain but superior to routine WBBS in the nuclear medicine department with limited resources of instrumentation and manpower.

    The role of image-guided thermal ablation techniques for the nonoperative local management of painful osseous metastatic disease has expanded during recent years, and several advantages of cryoablation in this setting have emerged. The purpose of this study is to retrospectively evaluate and report a single-center experience of CT-guided percutaneous cryoablation in the setting of painful musculoskeletal metastatic disease. This study was approved by the institutional review board and is compliant with the Health Insurance Portability and Accountability Act. Electronic medical records of all patients who underwent percutaneous image-guided palliative cryoablation at our institution were reviewed (n = 61). An intent-to-treat analysis was performed. Records were reviewed for demographic data and anatomical data, primary tumor type, procedure details, and outcome - including change in analgesic requirements (expressed as morphine equivalent dosages), pain scores (utilizing the clinically implemented visual analog scale), subsequent therapies (including radiation and/or surgery), and complications during the 24 h following the procedure and at 3 months. Patients were excluded (n = 7) if data were not retrospectively identifiable at the defined time points. Fifty-four tumors were ablated in 50 patients. There were statistically significant decreases in the median VAS score and narcotic usage at both 24 h and 3 months (p < 0.000). Six patients (11 %) incurred complications related to their therapy. Two patients had no relief at 24 h, of which both reported worsened pain at 3 months. One patient had initial relief but symptom recurrence at 3 months. Four patients went on to have radiation therapy of the ablation site at some point following the procedure. CT-guided cryoablation is a safe, effective, reproducible procedural option for the nonoperative local treatment of painful musculoskeletal metastatic disease. (orig.)

    Purpose: Wide-field radiation therapy (WFRT) is an effective treatment for widespread bone metastasis. We evaluated local-field irradiation (LFI) after fractionated WFRT (f-WFRT) for treating the patients with multiple painful bone lesions. Methods and Materials: From 1998 to 2007, 32 patients with multiple bone metastases were treated with fractionated LFI (f-LFI) after f-WFRT. All patients initially received 15 Gy in 5 fractions to a wide field, followed by LFI (9-15 Gy in 3 Gy fractions). Response was assessed by evaluating the degree of pain relief using a visual analog scale before radiotherapy, after f-WFRT, and after f-LFI. Results: Fractionated LFI following f-WFRT yielded an overall relief rate of 93.8% and a complete relief rate of 43.8%. The rate of the appearance of new disease was 6.3% for the patients with complete relief, 20.5% for the patients with a partial relief, and 50% for the patients with no relief. Conclusion: Fractionated LFI after f-WFRT is a well-tolerated and effective treatment for multiple metastatic bone disease.

    In 25 patients with prostatic cancer confirmed histologically, 24 patients had bone metastasis on the whole body bone scintigraphy. The extent of bone metastasis was estimated quantitatively by the computerized digitizer. At the same time, the number of the metastatic lesions was counted. The correlations between the area of metastatic lesions on the sup(99m)Tc-MDP bone scintigrams and ESR, LDH, total acid phosphatase, prostatic acid phosphatase, ALP and urinary hydroxyproline/creatinine levels were further investigated. The number of the metastatic lesions was also investigated with the same tumor markers. The results are as follows: 1) The extent of the metastatic lesions was showed more accurately by the area measured with the computerized digitalizer than by the number of metastatic lesions. 2) The correlation between the area of metastatic lesions and serum ALP levels was relatively high (..gamma.. = 0.75). But almost all were within normal limits. 3) As for the relation between the area of the metastatic lesions and the urinary hydroxyproline/creatinine levels, the correlation was high (..gamma.. = 0.78). And the hydroxyproline/creatinine levels were almost over the upper limit. Therefore, the urinary hydroxyproline/creatinine was considered as a good marker of the extent of bone metastasis.

    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.

  15. Do Laying Hens with Keel Bone Fractures Experience Pain?

    2012-01-01

    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.

    Full Text Available 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.

Thus, osteoprotection is an important part of therapy in breast cancer metastasized to bone, and bisphosphonates (BPs are a major therapeutic option. In this study, our objectives were to compare the side effects of oral versus intravenous BP treatment and to assess their clinical effectiveness.  Patients and methods: In this prospective randomized, open-label, non-inferiority trial, we enrolled breast cancer patients with at least one bone metastasis and an Eastern Cooperative Oncology Group performance status of 0–2. Patients were randomly assigned to one of the three treatment groups: A, 60 mg pamidronate intravenously q3w; B-iv, 900 mg clodronate intravenously q3w; and B-o, 2,400 mg oral clodronate daily. Assessments were performed at baseline and every 3 months thereafter.  Results: Between 1995 and 1999, 321 patients with confirmed bone metastases from breast cancer were included in the study. At first follow-up, gastrointestinal (GI tract side effects were most common, and adverse effects on the GI tract were more frequent in the oral treatment group (P=0.002 and P<0.001, respectively. There were no statistically significant differences among the treatment cohorts for other documented side effects (skin, serum electrolytes, urinary tract, immune system, and others. No significant differences in clinical effectiveness of BP treatment, as assessed by pain score, were detected among the groups; however, pathologic fractures

    Radionuclides have been long used for the palliation of skeletal-related metastatic pain. They are almost invariably used as the last resource for pain palliation. Their use as single agents with dose escalations, in combination with biphosphonates or chemotherapy is well known in the peer-reviewed literature; however, little is known about the combination between different agents. In our study, we used consecutive administration of 2 different radionuclides such as (186)Re-1,1-hydroxyethylidenediphosphonate ((186)Re-HEDP) and (89)Strontium Chloride ((89)Sr-Cl) separated by adequate period of time to allow bone marrow recovery in patients with high chance of bone pain relapse and compared it with (89)Sr-Cl and chemotherapy group and (186)Re-HEDP with bisphosphonates. The end result was that treatment with consecutive radionuclides was much more effective and safe than the other 2 groups.

    Background and purpose: To examine the incidence of pain flare following external beam radiotherapy and to determine what constitutes a meaningful change in pain scores in the treatment of bone metastases. Patients and methods: Patients with bone metastases treated with external beam radiotherapy were asked to score their pain on a scale of 0-10 before the treatment (baseline), daily during the treatment and for 10 days after completion of external beam radiation. Pain flare was defined as a two-point increase from baseline pain in the pain scale of 0-10 with no decrease in analgesic intake or a 25% increase in analgesic intake employing daily oral morphine equivalent with no decrease in pain score. To distinguish pain flare from progression of pain, we required the pain score and analgesic intake to return back to baseline levels after the increase/flare. They were also asked to indicate if their pain changed during that time compared to pre-treatment level. The change in pain score was compared with patient perception. Results: Eighty-eight patients were evaluated in this study. There were 49 male and 39 female patients with the median age of 70 years. Twelve of 88 patients (14%) had pain flare on day 1. The overall incidence of pain flare during the study period ranged from 2 to 16%. A total of 797 pain scorings were obtained. Patients perceived an improvement in pain when their self-reported pain score decreased by at least two points. Conclusions: Our study confirms the occurrence of pain flare following the external beam radiotherapy in the treatment of bone metastases. Further studies are required to predict who are at risk for flare. Appropriate measures can be taken to alleviate the pain flare. The finding in the meaningful change in pain scores supports the investigator-defined partial response used in some clinical trials

    Medulloblastoma is a relatively common intracranial neoplasm in childhood. Its extraneural spread was, until recently, thought to be a rare occurrence. Metastases are most commonly to bone. Five patients with medulloblastoma metastatic to bone are presented, and findings are compared to those of previous reports. Two of the five cases showed patchy extensive osteosclerosis of the pelvis and/or proximal femora. One case had concurrent lymph node involvement. In patients with past or present medulloblastoma and bone pain, metastases to bone should be excluded. Medulloblastoma metastatic to bone is a rare cause of extensive osteosclerosis. (orig.)

    Purpose: The incidence of painful bone metastases increases with longer survival times. Although external beam radiation therapy (EBRT) is an effective palliative treatment, it often requires several days from the start of treatment to produce a measurable reduction in pain scores and a qualitative amelioration of patient pain levels. Meanwhile, the use of analgesics remains the best approach early on in the treatment course. We investigated the role of radiation therapists as key personnel for collecting daily pain scores to supplement assessments by physician and oncology nursing staff and manage pain more effectively during radiation treatment. Methods and Materials: Daily pain scores were obtained by the radiation therapists for 89 patients undertaking a total of 124 courses of EBRT for bone metastases and compared with pretreatment pain scores. The majority of patients (71%) were treated to 30 Gy (range, 20-37.5) in 10 fractions (range, 8-15 fractions). Results: One hundred nineteen treatment courses (96%) were completed. Pain scores declined rapidly to 37.5%, 50%, and 75% of the pretreatment levels by Days 2, 4, and 10, respectively. Pain was improved in 91% of patients with only 4% of worse pain at the end of treatment. Improved pain scores were maintained in 83% of patients at 1-month follow-up, but in 35% of them, the pain was worse than at the end of treatment. Conclusions: Collection of daily pain scores by radiation therapists was associated with an effective reduction in pain scores early on during EBRT of painful osseous metastases.

    Full Text Available Women diagnosed with breast cancer often endorse psychosocial concerns prior to treatment, which may influence symptom experiences. Among these, low perceived social support relates to elevated fatigue. Those with low social support perceptions may also experience a greater sense of rejection. We sought to determine if social rejection concerns post-surgery predict fatigue interference 12 months later in women with non-metastatic breast cancer. Depressive symptoms and pain severity after completion of adjuvant therapy (six months post-surgery were examined as potential mediators. Women (N = 240 with non-metastatic breast cancer were recruited 2–10 weeks post-surgery. Multiple regression analyses examined relationships among variables adjusting for relevant covariates. Greater rejection concerns at study entry predicted greater fatigue interference 12 months later (p < 0.01. Pain severity after adjuvant therapy partially mediated the relationship between social rejection concerns and fatigue interference, with significant indirect (β = 0.06, 95% CI (0.009, 0.176 and direct effects (β = 0.18, SE = 0.07, t(146 = 2.78, p < 0.01, 95% CI (0.053, 0.311. Therefore, pain levels post-treatment may affect how concerns of social rejection relate to subsequent fatigue interference. Interventions targeting fears of social rejection and interpersonal skills early in treatment may reduce physical symptom burden during treatment and into survivorship.

  3. The Role of Purinergic Receptors in Cancer-Induced Bone Pain

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Cancer-induced bone pain severely compromises the quality of life of many patients suffering from bone metastasis, as current therapies leave some patients with inadequate pain relief. The recent development of specific animal models has increased the understanding of the molecular and cellular mechanisms underlying cancer-induced bone pain including the involvement of ATP and the purinergic receptors in the progression of the pain state. In nociception, ATP acts as an extracellular messenger to transmit sensory information both at the peripheral site of tissue damage and in the spinal cord. Several of the purinergic receptors have been shown to be important for the development and maintenance of neuropathic and inflammatory pain, and studies have demonstrated the importance of both peripheral and central mechanisms. We here provide an overview of the current literature on the role of purinergic receptors in cancer-induced bone pain with emphasis on some of the difficulties related to studying this complex pain state.

    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.)

    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.

    The case of an eight years old African boy who suffers from sickle cell-thalassemia is presented. In the course of the disease frequent pain attacks occurred within the abdomen and extremities, recently also within the trunk. Local pain, at some occasions in combination with local swelling and always positive laboratory parameters for inflammation, hindered a solely clinical differentiation between bone infarcts and osteomyelitis. Bone scintigraphy, eventually in combination with bone marrow scintigraphy, can assist the clinician in the differentiation of aseptic bone infarcts versus secondary osteomyelitis. Based on the presented case scintigraphic results for bone infarcts, osteomyelitis and special scintigraphic pattern seen in sickle cell disease are presented. Furthermore, problems regarding the interpretation of the scintigraphies in relation to the delayed time after the beginning of pain attacks are discussed. (author)

    We aimed to generate and characterize a novel cell line from a breast cancer bone metastasis to better study the progression of the disease. The cell line, P7731, was derived from a metastatic bone lesion of a breast cancer patient and assessed for marker expression. P7731 was analyzed for DNA copy number variation, somatic mutations, and gene expression and was compared with the primary tumor. P7731 cells are negative for estrogen receptor alpha (ERα), progesterone receptor (PR), and HER2 (triple-negative); strongly express vimentin (100% of cells positive) and also express cytokeratins 8/18 and 19 but at lower frequencies. Flow cytometry indicates P7731 cells are predominantly CD44 + /CD49f + /EpCAM - , consistent with a primitive, mesenchymal-like phenotype. The cell line is tumorigenic in immunocompromised mice. Exome sequencing identified a total of 45 and 76 somatic mutations in the primary tumor and cell line, respectively, of which 32 were identified in both samples and included mutations in known driver genes PIK3CA, TP53, and ARID1A. P7731 retains the DNA copy number alterations present in the matching primary tumor. Homozygous deletions detected in the cell line and in the primary tumor were found in regions containing three known (CDKN2A, CDKN2B, and CDKN1B) and 23 putative tumor suppressor genes. Cell line-specific gene amplification coupled with mRNA expression analysis revealed genes and pathways with potential pro-metastatic functions. This novel human breast cancer-bone metastasis cell line will be a useful model to study aspects of breast cancer biology, particularly metastasis-related changes from breast to bone.

    Skeletal scintigraphy is the first or second most frequently performed imaging procedure in most nuclear medicine departments. The uses of bone scan in orthopedic practice are multiple. Bone scans are often used to localize disease, to identify areas of focal increased physiological activity, and to evaluate pain. Bone scans are particularly useful in depicting and localizing small tumors. Bone scans may clarify the significance of radiographic abnormalities. When pain is poorly localized, a bone scan helps focus attention, particularly when it precisely corresponds to the questionable radiographic lesion. In order to do a survey about role of bone scan for the detection and localizing bone pain, a retrospective study was done about 37 patient who from 1373 to 1374 were admitted to the infectious department of Martyr Labafinejad having bone pain. The results of our studies showed that most common case of bone pain of this patients was due to brucellosis (brucella arthritis) with 19%, and other causes were cellulits with 13.15% osteomyelitis and D.J.D with 11%, septic arthritis, bone metastasis, bone abscesses, discopathy, infectious spondylitis, lymphoma, D.V.T. and reactive traumatic arthritis with 2.7%

    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

    Full Text Available Aim: to analyze expression of biomarkers CXCR4, IL11-RA, TFF1 and MLF1P, and clinicopathology in advanced breast cancer patients with bone metastatic. Methods: this is a cross-sectional study. Analysis was done against a total of 92 breast cancer patients, including 46 bone metastatic patients and 46 non-bone metastatic patients. Immunohistochemistry and microarray analysis was performed in 81 formalin fixed paraffin embedded (FFPE samples from 81 patients were used. Data were collected through medical records, immunohistochemistry (IHC, and microarray with nanoString nCounterTM. Results: this article is part one of a two stage reporting research results. In part one we got the results of the IHC analysis, IL11-RA with cut-off ≥103.5 showed OR 3.803 (95 % confidence interval [CI], 1.375-10.581, p=0.010, MLF1P with cut-off ≥83.0 OR 2.784 (95% CI, 1.009-7.681, p=0.048, and ER+ OR 7.640 (95 % CI, 2.599-22.459, p<0.000, were associated with bone metastastic incidences in advanced breast cancer, and were statistically significantly different. A combination of IL-11RA, MLF1P and ER+, showed an accuracy of approaching 80% to discriminate between bone metastatic and non bone metastatic in advanced breast cancer patients. Conclusion: IL11-RA, MLF1P, and ER+ were the determinants that were associated with increasing bone metastasis incidence.

    The aim of this study was to assess the diagnostic performance of 18 F-Fluoride positron emission tomography (PET) or positron emission tomography/computed tomography (PET/CT) compared with bone scintigraphy (BS) planar or BS planar and single photon emission computed tomography (SPECT) in evaluating patients with metastatic bone tumor. We performed a meta-analysis of all available studies addressing the diagnostic accuracy of 18 F-Fluoride PET, 18 F-Fluoride PET/CT, BS planar, and BS planar and SPECT for detecting the metastatic bone tumor. We determined sensitivities and specificities across studies, calculated positive and negative likelihood ratios, and drew summary receiver operating characteristic curves using hierarchical regression models. We also compared the effective dose and cost-effectiveness estimated by data from the enrolled studies between 18 F-Fluoride PET or PET/CT and BS planar or BS planar and SPECT. When comparing all studies with data on 18 F-Fluoride PET or PET/CT, sensitivity and specificity were 96.2% [95% confidence interval (CI) 93.5-98.9%] and 98.5% (95% CI 97.0-100%), respectively, on a patient basis and 96.9% (95% CI 95.9-98.0%) and 98.0% (95% CI 97.1-98.9%), respectively, on a lesion basis. The Az values of 18 F-Fluoride PET or PET/CT were 0.986 for the patient basis and 0.905 for the lesion basis, whereas those of BS or BS and SPECT were 0.866 for the patient basis and 0.854 for the lesion basis. However, the estimated effective dose and average cost-effective ratio were poorer for 18 F-Fluoride PET or PET/CT than those of BS planar or BS planar and SPECT. 18 F-Fluoride PET or PET/CT has excellent diagnostic performance for the detection of metastatic bone tumor, but the estimated effective dose and average cost-effective ratio are at a disadvantage compared with BS planar or BS planar and SPECT.

    To investigate the relationship between patient and tumor characteristics and pain response in patients with metastatic bone disease, and construct and internally validate a clinical prediction model for pain response to guide individualized treatment decision making. A total of 965 patients with painful bone metastases undergoing palliative radiation therapy at a tertiary referral center between 1999 and 2007 were identified. Pain scores were measured at 1, 2, and 3 months after radiation therapy. Pain response was defined as at least a 2-point decrease on a pain score scale of 0-10, without increase in analgesics, or an analgesic decrease of at least 25% without an increase in pain score. Thirteen candidate predictors were identified from the literature and expert experience. After multiple imputation, final predictors were selected using stepwise regression and collapsed into a prediction model. Model performance was evaluated by calibration and discrimination and corrected for optimism. Overall 462 patients (47.9%) showed a response. Primary tumor site, performance status, and baseline pain score were predictive for pain response, with a corrected c-statistic of 0.63. The predicted response rates after radiation therapy increased from 37.5% for patients with the highest risk score to 79.8% for patients with the lowest risk score and were in good agreement with the observed response rates. A prediction score for pain response after palliative radiation therapy was developed. The model performance was moderate, showing that prediction of pain response is difficult. New biomarkers and predictors may lead to improved identification of the large group of patients who are unlikely to respond and who may benefit from other or innovative treatment options.

  14. Palliation of bone cancer pain by antagonists of platelet-activating factor receptors.

    Directory of Open Access Journals (Sweden)

    Full Text Available Bone cancer pain is the most severe among cancer pain and is often resistant to current analgesics. Thus, the development of novel analgesics effective at treating bone cancer pain are desired. Platelet-activating factor (PAF receptor antagonists were recently demonstrated to have effective pain relieving effects on neuropathic pain in several animal models. The present study examined the pain relieving effect of PAF receptor antagonists on bone cancer pain using the femur bone cancer (FBC model in mice. Animals were injected with osteolytic NCTC2472 cells into the tibia, and subsequently the effects of PAF receptor antagonists on pain behaviors were evaluated. Chemical structurally different type of antagonists, TCV-309, BN 50739 and WEB 2086 ameliorated the allodynia and improved pain behaviors such as guarding behavior and limb-use abnormalities in FBC model mice. The pain relieving effects of these antagonists were achieved with low doses and were long lasting. Blockade of spinal PAF receptors by intrathecal injection of TCV-309 and WEB 2086 or knockdown of the expression of spinal PAF receptor protein by intrathecal transfer of PAF receptor siRNA also produced a pain relieving effect. The amount of an inducible PAF synthesis enzyme, lysophosphatidylcholine acyltransferase 2 (LPCAT2 protein significantly increased in the spinal cord after transplantation of NCTC 2472 tumor cells into mouse tibia. The combination of morphine with PAF receptor antagonists develops marked enhancement of the analgesic effect against bone cancer pain without affecting morphine-induced constipation. Repeated administration of TCV-309 suppressed the appearance of pain behaviors and prolonged survival of FBC mice. The present results suggest that PAF receptor antagonists in combination with, or without, opioids may represent a new strategy for the treatment of persistent bone cancer pain and improve the quality of life of patients.

    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. Furthermore, acute treatment with the selective P2X7 receptor antagonist, A-438079, failed to alleviate pain-related behaviours in models of bone cancer pain...... with and without astrocyte activation (BALB/cJ or C3H mice inoculated with 4T1 mammary cancer cells or NCTC 2472 osteosarcoma cells, respectively), suggesting that astrocytic P2X7 receptors play a negligible role in bone cancer pain. The results support the hypothesis that bone cancer pain is a separate pain state...

  16. Optimization and In Vivo Profiling of a Refined Rat Model of Walker 256 Breast Cancer Cell-Induced Bone Pain Using Behavioral, Radiological, Histological, Immunohistochemical and Pharmacological Methods

    Full Text Available In the majority of patients with advanced breast cancer, there is metastatic spread to bones resulting in pain. Clinically available drug treatments for alleviation of breast cancer-induced bone pain (BCIBP often produce inadequate pain relief due to dose-limiting side-effects. A major impediment to the discovery of novel well-tolerated analgesic agents for the relief of pain due to bony metastases is the fact that most cancer-induced bone pain models in rodents relied on the systemic injection of cancer cells, causing widespread formation of cancer metastases and poor general animal health. Herein, we have established an optimized, clinically relevant Wistar Han female rat model of breast cancer induced bone pain which was characterized using behavioral assessments, radiology, histology, immunohistochemistry and pharmacological methods. In this model that is based on unilateral intra-tibial injection (ITI of Walker 256 carcinoma cells, animals maintained good health for at least 66 days post-ITI. The temporal development of hindpaw hypersensitivity depended on the initial number of Walker 256 cells inoculated in the tibiae. Hindpaw hypersensitivity resolved after approximately 25 days, in the continued presence of bone tumors as evidenced by ex vivo histology, micro-computed tomography scans and immunohistochemical assessments of tibiae. A possible role for the endogenous opioid system as an internal factor mediating the self-resolving nature of BCIBP was identified based upon the observation that naloxone, a non-selective opioid antagonist, caused the re-emergence of hindpaw hypersensitivity. Bolus dose injections of morphine, gabapentin, amitriptyline and meloxicam all alleviated hindpaw hypersensitivity in a dose-dependent manner. This is a first systematic pharmacological profiling of this model by testing standard analgesic drugs from four important diverse classes, which are used to treat cancer induced bone pain in the clinical setting

  17. Severe pegfilgrastim-induced bone pain completely alleviated with loratadine: A case report.

    Febrile neutropenia is an oncologic emergency that can result in serious consequences. Granulocyte colony stimulating factors (G-CSFs) are often used as prophylaxis for febrile neutropenia. Bone pain is the most notorious adverse effect caused by G-CSFs. Specifically, with pegfilgrastim (Neulasta(®)), the incidence of bone pain is higher in practice than was observed during clinical trials. Traditional analgesics, such as non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, can be ineffective in severe pegfilgrastim-induced bone pain. With the high frequency of this adverse effect, it is clear that health practitioners need additional treatment options for patients who experience severe pegfilgrastim-induced bone pain. The mechanisms of bone pain secondary to G-CSFs are not fully known, but research has shown that histamine release is involved in the inflammatory process. There is scant previous clinical data on antihistamine use in the management of G-CSF-induced pain. We present the first case report in which loratadine prophylaxis completely alleviated NSAID-resistant severe pain secondary to pegfilgrastim. The result showed that loratadine may be a promising option for severe, resistant pegfilgrastim-induced bone pain. Further clinical studies are warranted and ongoing. © The Author(s) 2014.

    Purpose: To determine whether fluorodeoxyglucose positron emission tomography (FDG-PET) before and after palliative radiation therapy (RT) can predict long-term pain control in patients with painful bone metastases. Methods and Materials: Thirty-one patients with bone metastases who received RT were prospectively included. Forty painful metastatic treatment fields were evaluated. All patients had undergone pre-RT and post-RT PET/CT scanning. We evaluated the relationships between the pre-RT, post-RT, and changes in maximum standardized uptake value (SUV{sub max}) and the pain response, and between SUV{sub max} and pain relapse of the bone metastases in the treatment field. In addition, we compared the SUV{sub max} according to the length of time from the completion of RT to pain relapse of the bone metastases. Results: Regarding the pain response at 4 weeks after the completion of RT, there were 36 lesions of 27 patients in the responder group and 4 lesions of 4 patients in the nonresponder group. Changes in the SUV{sub max} differed significantly between the responder and nonresponder groups in both the early and delayed phases (P=.0292 and P=.0139, respectively), but no relationship was observed between the pre-RT and post-RT SUV{sub max} relative to the pain response. The responder group was evaluated for the rate of relapse. Thirty-five lesions of 26 patients in the responder group were evaluated, because 1 patient died of acute renal failure at 2 months after RT. Twelve lesions (34%) showed pain relapse, and 23 lesions (66%) did not. There were significant differences between the relapse and nonrelapse patients in terms of the pre-RT (early/delayed phases: P<.0001/P<.0001), post-RT (P=.0199/P=.0261), and changes in SUV{sub max} (P=.0004/P=.004). Conclusions: FDG-PET may help predict the outcome of pain control in the treatment field after palliative RT for painful bone metastases.

    Metastatic bone disease is increasing in association with ever-improving medical management of osteophylic malignant conditions. The precise timing of surgical intervention for secondary lesions in long bones can be difficult to determine. This paper aims to evaluate a classic scoring system. All radiographs were examined twice by three orthopaedic oncologists and scored according to the Mirels\\' scoring system. The Kappa statistic was used for the purpose of statistical analysis. The results show agreement between observers (κ = 0.35-0.61) for overall scores at the two time intervals. Inter-observer agreement was also seen with subset analysis of size (κ = 0.27-0.60), site (κ = 0.77-1.0) and nature of the lesion (κ = 0.55-0.81). Similarly, low levels of intra-observer variability were noted for each of the three surgeons (κ= 0.34, 0.39, and 0.78, respectively). These results indicate a reliable, repeatable assessment of bony metastases. We continue to advocate its use in the management of patients with long bone metastases.

    The aim of study was evaluation of the results of the bone scan in patients suffering back for more than 2 weeks. In 120 patients with back pain for more than 2 w ks who referred for bone scan significant numbers showed inflammatory disease including spondylitis and/ or saltcellar's in bone scintigraphy. Because of low sensitivity of the other imaging modalities in detection of this inflammatory lesions, the bone scan can be used as primary imaging method in evaluation of the patients with back pain in certain geographic regions in which special pathogens endemic ally exist. This study was performed in Hamedan in which Brucella infection and to lesser extent Tuberculosis are endemic

    Prostate cancer (adenocarcinoma of the prostate) is the most widespread cancer in men. It causes significant suffering and mortality due to metastatic disease. The main therapy for metastatic prostate cancer (MPC) includes androgen manipulation, chemotherapy, and radiotherapy and/or radioisotopes. However, these therapeutic approaches are considered palliative at this stage, and their significant side effects can cause further decline in patients' quality of life and increase non-cancer-related morbidity/mortality. In this study, the authors have used the infusion of dimethyl sulfoxide-sodium bicarbonate (DMSO-SB) to treat 18 patients with MPC. The 90-day follow-up of the patients having undergone the proposed therapeutic regimen showed significant improvement in clinical symptoms, blood and biochemistry tests, and quality of life. There were no major side effects from the treatment. In searching for new and better methods for palliative treatment and pain relief, this study strongly suggested therapy with DMSO-SB infusions could provide a rational alternative to conventional treatment for patients with MPC.

    To evaluate the feasibility and effectiveness of computed tomography (CT)-guided percutaneous screw fixation plus cementoplasty (PSFPC), for either treatment of painful metastatic fractures or prevention of pathological fractures, in patients who are not candidates for surgical stabilization. Twenty-seven patients with 34 metastatic bone lesions underwent CT-guided PSFPC. Bone metastases were located in the vertebral column, femur, and pelvis. The primary end point was the evaluation of feasibility and complications of the procedure, in addition to the length of hospital stay. Pain severity was estimated before treatment and 1 and 6 months after the procedure using the visual analog scale (VAS). Functional outcome was assessed by improved patient walking ability. All sessions were completed and well tolerated. There were no complications related to either incorrect positioning of the screws during bone fixation or leakage of cement. All patients were able to walk within 6 h after the procedure and the average length of hospital stay was 2 days. The mean VAS score decreased from 7.1 (range, 4-9) before treatment to 1.6 (range, 0-6), 1 month after treatment, and to 1.4 (range 0-6) 6 months after treatment. Neither loosening of the screws nor additional bone fractures occurred during a median follow-up of 6 months. Our results suggest that PSFPC might be a safe and effective procedure that allows the stabilization of the fracture and the prevention of pathological fractures with significant pain relief and good recovery of walking ability, although further studies are required to confirm this preliminary experience.

    Purpose: To study quality of life (QoL) in responders and nonresponders after radiation therapy for painful bone metastases; and to identify factors predictive for a pain response. Patients and Methods: The prospectively collected data of 956 patients with breast, prostate, and lung cancer within the Dutch Bone Metastasis Study were used. These patients, irradiated for painful bone metastases, rated pain, QoL, and overall health at baseline and weekly afterward for 12 weeks. Using generalized estimating equations analysis, the course of QoL was studied, adjusted for primary tumor. To identify predictive variables, proportional hazard analyses were performed, taking into account death as a competing risk, and C-statistics were calculated for discriminative value. Results: In total, 722 patients (76%) responded to radiation therapy. During follow-up, responders had a better QoL in all domains compared with nonresponders. Patients with breast or prostate cancer had a better QoL than patients with lung cancer. In multivariate analysis, baseline predictors for a pain response were breast or prostate cancer as primary tumor, younger age, good performance status, absence of visceral metastases, and using opioids. The discriminative ability of the model was low (C-statistic: 0.56). Conclusions: Responding patients show a better QoL after radiation therapy for painful bone metastases than nonresponders. Our model did not have enough discriminative power to predict which patients are likely to respond to radiation therapy. Therefore, radiation therapy should be offered to all patients with painful bone metastases, aiming to decrease pain and improve QoL.

  7. The impact of bone marrow micrometastases on metastatic disease-free survival in patients with colorectal carcinoma.

    AIMS: The biological relevance of bone marrow micrometastases (BMM) in colorectal cancer remains unknown. Here, we investigate their nature by examining the impact of the presence of BMM on metastatic disease-free survival in a cohort of patients with this disease. METHODS: Sixty-three consecutive patients undergoing surgery for colorectal cancer of any stage were studied after approval of the study protocol by the local ethics committee and with full individual informed consent. All had bilateral iliac crest bone marrow aspirates prior to operation. Aspirates were then examined for the presence of aberrant cytokeratin-18-positive cells by a blinded observer using both flow cytometric and APAAP immunohistochemical techniques. RESULTS: Mean follow-up after surgery was 4.6 years (range 1.9-6.9) for those without hepatic metastases at diagnosis. Seven of 34 patients with Dukes\\' stage A or B developed metastatic disease after a mean interval of 4.7 years (range 3.8-6.8). However, only 2 of these patients demonstrated BMM at the time of surgery. Nine of 15 patients with Dukes\\' C carcinoma at the time of surgery subsequently developed metastases after a mean interval of 4.4 years (range 1.9-6.9). Again, only two of these patients had BMM detectable initially. In only three of the 14 patients known to have metastases at the time of operation (i.e. Dukes\\'\\'D\\' disease) were BMM found. CONCLUSION: The presence of BMM as detected by this methodology was not predictive of tumour recurrence or metastasis. This study does not support the consideration of adjuvant therapy based on the presence of BMM at a single pre-operative time point in patients with colorectal cancer.

    A new method for measurement of 24-hr whole body retention (WBR) of Tc-99mMDP, using a thyroid uptake probe was established and its clinical significance was evaluated in 102 patients with various bone disorders, including metabolic and metastatic bone diseases, aged above 20 years old. Reproducibility of 24-hr WBR in 10 patients was very good (r=0.996). The 24-hr WBR of Tc-99mMDP in the normal subjects was 30.4 +- 4.6%. The WBR values of chronic renal failure, metastatic bone disease and hyperthyroidism groups were 98.4 +- 3.0, 44.0 +- 8.0, 40,6 +- 6.3% respectively, which were significantly higher (p < 0.001). However the WBR of steroid-induced osteoporotic group was significantly lower (17.3 +- 5.4%) as compared with the normal group (p < 0.001). Based on these results the method is simple, reproducible and accurate to measure 24-hr WBR of Tc-99mMDP. Quantification of WBR is of great clinical value to diagnose metabolic bone disease and to follow-up metabolic and metastatic bone disease after treatment

    Purpose: In the case of metastatic involvement of the sacrum with destruction and consecutive pathological fracture, intense disabling pain is one of the defining factors. The feasibility, safety and pain development with cement augmentation were to be investigated. Materials and Methods: CT-guided balloon sacroplasty was conducted in 10 patients with metastasis-induced bone destruction of the sacrum. After establishment of the entry point, a K-wire was first introduced as far as the central tumor lesion via the short, or transiliac axis. A cannula was then positioned over the wire. Under CT guidance, a balloon catheter was introduced through the cannula and inflated and deflated several times. The PMMA cement was then injected into the preformed cavity. The procedure was completed by a spiral CT control using the thin-slice technique. Pain intensity was determined using a visual analog scale (VAS) before the procedure, on the 2nd postoperative day and 6 months after the intervention. Finally, the patients were asked to state how satisfied they were. Results: Balloon sacroplasty was technically feasible in all patients. The control CT scan showed central distribution of the cement in the tumor lesion. On average 6+/-1.78 (4-10) ml of PMMA cement were introduced per treated lesion. A significant (p < 0.001) reduction in pain according to the VAS occurred in all patients from 9.3+/-0.67 (8-10) pre-operatively to 2.7+/-1.28 (1-5) on the 2nd postoperative day and 2.9+/-0.81 (2-5) 6 months after the intervention. All of the patients were re-mobilized after the procedure and underwent the further therapeutic measures as planned. Conclusion: Balloon sacroplasty is a helpful therapeutic option in the overall palliative treatment of patients with tumor-induced destruction. It is a safe and practicable procedure that markedly reduces disabling pain. (orig.)

    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.

    2011-01-01

    Purpose: To analyze the relationship between mean absorbed dose to the pubic bone after pelvic radiotherapy for gynecological cancer and occurrence of pubic bone pain among long-term survivors. Methods and Materials: In an unselected, population-based study, we identified 823 long-term gynecological cancer survivors treated with pelvic radiotherapy during 1991-2003. For comparison, we used a non-radiation-treated control population of 478 matched women from the Swedish Population Register. Pain, intensity of pain, and functional impairment due to pain in the pubic bone were assessed with a study-specific postal questionnaire. Results: We analyzed data from 650 survivors (participation rate 79%) with median follow-up of 6.3 years (range, 2.3-15.0 years) along with 344 control women (participation rate, 72 %). Ten percent of the survivors were treated with radiotherapy; ninety percent with surgery plus radiotherapy. Brachytherapy was added in 81%. Complete treatment records were recovered for 538/650 survivors, with dose distribution data including dose-volume histograms over the pubic bone. Pubic bone pain was reported by 73 survivors (11%); 59/517 (11%) had been exposed to mean absorbed external beam doses <52.5 Gy to the pubic bone and 5/12 (42%) to mean absorbed external beam doses ≥52.5 Gy. Thirty-three survivors reported pain affecting sleep, a 13-fold increased prevalence compared with control women. Forty-nine survivors reported functional impairment measured as pain walking indoors, a 10-fold increased prevalence. Conclusions: Mean absorbed external beam dose above 52.5 Gy to the pubic bone increases the occurrence of pain in the pubic bone and may affect daily life of long-term survivors treated with radiotherapy for gynecological cancer.

    Melorheostosis is a very rare sclerosing bone disorder that involves frequently one limb. It may be asymptomatic, but pain and limb deformity may occur and can be very debilitating. Different reports have indicated efficacy of bisphosphonates (pamidronate and etidronate) on symptoms. We report an adult patient with a very painful melorheostosis, who  improved after treatment with zoledronate, either on symptoms or on bone scans. PMID:23813581

    Bisphosphonates and denosumab are well-established therapies to reduce the frequency and severity of skeletal-related events in patients with bone metastasis. However, the analgesic effect of these medications on bone pain is uncertain. To identify, critically appraise and synthesize existing evidence to answer the following questions: 'In adult patients with metastatic bone pain, what is the evidence that bisphosphonates and denosumab are effective and safe in controlling pain?' and 'What is the most appropriate schedule of bisphosphonate/denosumab administration to control bone pain?'. This review also updates the 2002 Cochrane review 'Bisphosphonates for the relief of pain secondary to bone metastases'. Standard systematic review and narrative synthesis. MEDLINE, EMBASE and Cochrane CENTRAL databases were searched for relevant articles published through 31 January 2014. A manual search was also performed. Study inclusion criteria were: a) conducted in adult patients; b) randomized controlled trial or meta-analisys; c) reported efficacy of bisphosphonates or denosumab on pain and/or decribed side effects versus placebo or other bisphosphonate; and d) English language. The database search yielded 1585 studies, of which 43 (enrolling 8595 and 7590 patients, respectively, in bisphosphonate and denosumab trials) met the inclusion criteria. Twenty-two (79%) of the 28 placebo-controlled trials found no analgesic benefit for bisphosphonates. None of the denosumab studies assessed direct pain relief. Evidence to support an analgesic role for bisphosphonates and denosumab is weak. Bisphosphonates and denosumab appear to be beneficial in preventing pain by delaying the onset of bone pain rather than by producing an analgesic effect per se.

    Deep pain is neglected compared with cutaneous sources. Pressure algometry has been validated in the clinic for assessment of bone-related pain in humans. In animal models of bone-related pain, we have validated the Randall Selitto behavioural test for assessment of acute and pathological bone pain and compared the outcome with more traditional pain-related behaviour measures. Randall Selitto pressure algometry was performed over the anteromedial part of the tibia in naïve rats, sham-operated rats, and rats inoculated with MRMT-1 carcinoma cells in the left tibia, and the effect of morphine was investigated. Randall Selitto measures of cancer-induced bone pain were supplemented by von Frey testing, weight-bearing and limb use test. Contribution of cutaneous nociception to Randall Selitto measures were examined by local anaesthesia. Randall Selitto pressure algometry over the tibia resulted in reproducible withdrawal thresholds, which were dose-dependently increased by morphine. Cutaneous nociception did not contribute to Randall Selitto measures. In cancer-bearing animals, compared with sham, significant differences in pain-related behaviours were demonstrated by the Randall Selitto test on day 17 and 21 post-surgery. A difference was also demonstrated by von Frey testing, weight-bearing and limb use tests. Our results indicate that pressure applied by the Randall Selitto algometer on a region, where the bone is close to the skin, may offer a way to measure bone-related pain in animal models and could provide a supplement to the traditional behavioural tests and a means to study deep pain. © 2014 European Pain Federation - EFIC®

    Bone mineral density (BMD) and clinical status of 40 patients with a chronic, unilateral patellofemoral pain syndrome (PFPS) were determinated. The mean duration of the disease at the time of the follow-up was 7.6 +/- 1.8 (SD) years. The BMD was measured at the spine (L2-L4), and the femoral neck, trochanter area of the femur, distal femur, patella, proximal tibia, and calcaneus of both lower extremities using a dual-energy X-ray absorptiometric (DXA) scanner. The mean BMD of the affected limb (compared with the unaffected side) was significantly lower in the distal femur (-3.3%; P = 0.002), patella (-2.5%; P = 0.016), and proximal tibia (-1.9%; P = 0.008). The femoral neck, trochanter area of the femur, and calcaneus showed no significant side-to-side differences, and the spinal BMDs of men and women with the PFPS were comparable with the manufacturer's age-adjusted reference values for Western European men and women. The relative BMDs of the affected knee showed strongest correlation with the muscle strength of the same knee: the better the muscle strength compared with the healthy knee, the higher the relative BMD (r = 0.56-0.58 with P < 0.001 in each anatomic site of the knee). In the stepwise regression analysis, low body weight or low body mass index, high level of physical activity, the patient's good subjective overall assessment of his/her affected knee, and short duration of the symptoms were also independent predictors of the high relative BMD in the affected knee so that along with the muscle strength these variables could account for 51% of the variation seen in the relative BMD of the femur, 61% in the patella, and 54% in the proximal tibia. In conclusion, chronic patellofemoral pain syndrome results in a significantly decreased BMD in the knee region of the affected limb. The spine, proximal femur, and calcaneus are not affected. Recovery of normal muscle strength and knee function seems to be of great importance for good BMD.

    Bone pain due to bony metastases can seriously affect a patient's quality of life. External irradiation, narcotic drugs and polyphosphates may cause important side effects or are expensive, therefore in many patients radionuclide treatment using a single dose of beta emitting bone seeking radiopharmaceuticals has become widely accepted. Except 32-Phosphorus (32-P) all of them are expensive and difficult to obtain in certain countries. The aim of the study was to evaluate safety and efficacy of 32-P for palliation of bone pain due to bony metastases by comparing it to 89-Strontium (89-Sr), the most commonly used radiopharmaceutical for bone pain palliation in the framework of a prospective IAEA co-ordinated multicenter study. A very strict protocol for unified patient inclusion and follow up was used. 93 cancer patients with osteoblastic bony metastases were included into the study, 48 were treated by 89-Sr (150 MBq) and 45 by 32-P (450 MBq). Pain score, analgesic consumption, quality of life, and indices of bone marrow depression were monitored 2 weeks pre- and up to 4 months post treatment. Favourable response to treatment was recorded in 75% of the patients treated with 89-Sr and in 60% of those treated with 32-P (p=0,122). There was no significant difference between the duration of favourable effect for both radiopharmaceuticals. Moderate decrease of white blood cell (WBC) and platelet counts, and haemoglobin (Hb) levels was detected more often in the 32-P treated group. Although 32-P appears to be more toxic, no toxic effects requiring specific treatment were seen in either group. Due to its comparable efficacy and safety, general availability and low cost its more widespread use should be encouraged to increase quality of life and reduce cost of medical care of patients with intractable bone pain due to cancer metastases.

    2002-01-01

    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.)

    Cancer-induced bone pain (CIBP) is a common chronic pain characterized by 2 components, ongoing pain and breakthrough pain. Tanshinone IIA (TSN IIA) is a bioactive constituent of the traditional Chinese medicine Danshen, which has been reported to have an antinociceptive effect on neuropathic and inflammatory pain through downregulation of the late proinflammatory cytokine high-mobility group protein B1 (HMGB1). To assess the antinociceptive effect of TSN IIA on CIBP. A randomized, double-blind, controlled animal trial was performed. University lab in China. A rat CIBP model was established by injecting Walker 256 mammary gland carcinoma cells into the intramedullary cavity of the tibia. Both ongoing pain, e.g., flinching and guarding, and breakthrough pain, e.g., limb use and von Frey threshold, were evaluated. The effects of intraperitoneally administered TSN IIA on pain behavior and the expression levels of spinal HMGB1, interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha, and IL-6 were determined. The effect of TSN IIA on the electrically evoked response of spinal wide-dynamic range (WDR) neurons was performed in vivo. TSN IIA dose-dependently inhibited cancer-induced ongoing pain and breakthrough pain. The expression levels of spinal HMGB1 and other inflammatory factors (IL-1beta, TNF-alpha, and IL-6) were increased in the rat model, but they were suppressed by TSN IIA in a dose-dependent manner. Moreover, TSN IIA significantly inhibited the neuronal responses of WDR neurons in spinal deep layers. Further studies are warranted to ascertain how TSN IIA attenuates cancer-induced ongoing pain. Our results indicate that TSN IIA attenuates cancer-induced ongoing pain and breakthrough pain, possibly via suppression of central sensitization in CIBP rats. Therefore, we have provided strong evidence supporting TSN IIA as a potential and effective therapy for relieving CIBP.

    To evaluate whether the apparent diffusion coefficient (ADC) of metastatic bone tumours on diffusion-weighted magnetic resonance imaging (MRI) images differs according to the type of primary cancer, the affected bone, and clinical factors. For this retrospective study, two radiologists reviewed MRI images, including ADC maps, of 67 patients (M:F=38:29; median age, 48 years) who were diagnosed with bone metastasis by means of histological or clinical confirmation. The primary tumours included 29 lung adenocarcinomas, 15 invasive ductal adenocarcinomas of the breast, 13 hepatocellular carcinomas, six prostatic carcinomas, and four renal cell carcinomas. ADC values of the metastatic tumour were compared according to the type of primary malignancy, the affected bone, and the age and sex of the patient using Kruskal-Wallis and Mann-Whitney U-tests with Bonferroni correction. In addition, pre-contrast CT images were available in 38 of 67 patients; a subanalysis of the CT radiodensity and ADC values were performed with Spearman correlation. The mean, standard deviation, and minimum and maximum values of the ADC of metastatic bone tumours did not differ significantly according to type of primary malignancy, the affected bone, or clinical variables (p>0.1). The ADC value was not significantly correlated with CT radiodensity (p=0.24). Intra- and interobserver agreements for the mean ADC values were excellent (intra-observer: p=0.98; interobserver: p=0.98). Assessment of the ADC value of metastatic bone tumours is not reliable for differentiation of the type of primary cancer. Copyright © 2015 The Royal College of Radiologists.

    Full Text Available Abstract Background The most frequent pain in patients with metastatic breast and prostate cancer is bone pain, which can be severe and difficult to treat. The mechanisms underlying this pain remain unclear. Here we investigated the role of c-jun N-terminal kinase (JNK pathway in the spinal cord in cancer-induced bone pain (CIBP. Results In this study, we used an established rat CIBP model to investigate the possible role of JNK activation in the spinal cord. After intra-tibial inoculation with Walker 256 rat mammary gland carcinoma cells, the rats displayed mechanical allodynia on day 5, which lasted to day 16. The activation of JNK in neurons and astrocytes in the spinal cord was found on day 12 and day 16 after intra-tibial inoculation with carcinoma cells. A single intrathecal injection with JNK inhibitor SP600125 by lumbar puncture attenuated mechanical allodynia on day 12, and repeated intrathecal injection of SP600126 from day 10 to day 14 had a cumulative analgesic effect on CIBP. Conclusions Taken together, our results demonstrated for the first time that JNK activation in the spinal cord is required in the maintenance of CIBP. Inhibition of the spinal JNK pathway may provide a new therapy for CIBP management.

    The purpose of this study was to elucidate the central processing of painful mechanical stimulation to muscle and bone by measuring blood oxygen level-dependent signal changes using functional magnetic resonance imaging (fMRI). Twelve healthy volunteers were enrolled. Mechanical pressure on muscle and bone were applied at the right lower leg by an algometer. Intensities were adjusted to cause weak and strong pain sensation at either target site in preliminary testing. Brain activation in response to mechanical nociceptive stimulation targeting muscle and bone were measured by fMRI and analyzed. Painful mechanical stimulation targeting muscle and bone activated the common areas including bilateral insula, anterior cingulate cortex, posterior cingulate cortex, secondary somatosensory cortex (S2), inferior parietal lobe, and basal ganglia. The contralateral S2 was more activated by strong stimulation than by weak stimulation. Some areas in the basal ganglia (bilateral putamen and caudate nucleus) were more activated by muscle stimulation than by bone stimulation. The putamen and caudate nucleus may have a more significant role in brain processing of muscle pain compared with bone pain.

    Background: Pain caused by bone metastases has a severe impact on the quality of life for many patients with cancer. Good translational in vivo models are required to understand the molecular mechanism and develop better treatment. In the current study we evaluated the influence of sex differences...... a significantly greater bioluminescence signal on day 2 compared to male mice and, in addition, a significant earlier onset of pain-related behavior was observed in the females. No sex difference was observed for bone degradation. Finally, a strong correlation between pain-related behavior and bone degradation...... was observed for both sexes. Conclusion: Although differences were observed between the sexes, these were minor and did not affect the overall progression of the pain state....

  10. Use of Animal Models in Understanding Cancer-induced Bone Pain

    2015-01-01

    Full Text Available Many common cancers have a propensity to metastasize to bone. Although malignancies often go undetected in their native tissues, bone metastases produce excruciating pain that severely compromises patient quality of life. Cancer-induced bone pain (CIBP is poorly managed with existing medications, and its multifaceted etiology remains to be fully elucidated. Novel analgesic targets arise as more is learned about this complex and distinct pain state. Over the past two decades, multiple animal models have been developed to study CIBP's unique pathology and identify therapeutic targets. Here, we review animal models of CIBP and the mechanistic insights gained as these models evolve. Findings from immunocompromised and immunocompetent host systems are discussed separately to highlight the effect of model choice on outcome. Gaining an understanding of the unique neuromolecular profile of cancer pain through the use of appropriate animal models will aid in the development of more effective therapeutics for CIBP.

    2015-05-01

    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.

    This multicenter study assessed the feasibility of conducting a phase III trial of transcutaneous electrical nerve stimulation (TENS) in patients with cancer bone pain recruited from palliative care services. Eligible patients received active and placebo TENS for 1 hour at site of pain in a randomized crossover design; median interval between applications 3 days. Responses assessed at 30 and 60 minutes included numerical and verbal ratings of pain at rest and on movement, and pain relief. Recruitment, tolerability, adverse events, and effectiveness of blinding were also evaluated. Twenty-four patients were randomised and 19 completed both applications. The intervention was well tolerated. Five patients withdrew: 3 due to deteriorating performance status, and 2 due to increased pain (1 each following active and placebo TENS). Confidence interval estimation around the differences in outcomes between active and placebo TENS suggests that TENS has the potential to decrease pain on movement more than pain on rest. Nine patients did not consider that a placebo was used; the remaining 10 correctly identified placebo TENS. Feasibility studies are important in palliative care prior to undertaking clinical trials. Our findings suggest that further work is required on recruitment strategies and refining the control arm before evaluating TENS in cancer bone pain. Cancer bone pain is common and severe, and partly mediated by hyperexcitability. Animal studies suggest that Transcutaneous Electrical Nerve Stimulation can reduce hyperalgesia. This study examined the feasibility of evaluating TENS in patients with cancer bone pain in order to optimize methods before a phase III trial. Copyright 2010 American Pain Society.

    Full Text Available The expression of the immunosuppressive molecules IL-10 and arginase 1 (ARG-1, and of FOXP3 and CD163, as markers of regulatory T cells (Treg and macrophages, respectively, was evaluated in bone marrow (BM and peripheral blood (PB samples collected at diagnosis from patients with metastatic neuroblastoma (NB. IL-10 and ARG-1 plasma concentrations were measured and the association of each parameter with patients’ outcome was tested. The percentages of immunosuppressive Treg and type-1 regulatory (Tr1 cells were also determined. In both BM and PB samples, IL-10 mRNA expression was higher in metastatic NB patients than in controls. IL-10 plasma concentration was higher in patients with NB regardless of stage. Neither IL-10 expression nor IL-10 plasma concentration significantly associated with patient survival. In PB samples from metastatic NB patients, ARG-1 and CD163 expression was higher than in controls but their expression did not associate with survival. Moreover, ARG-1 plasma concentration was lower than in controls, and no association with patient outcome was found. Finally, in metastatic NB patients, the percentage of circulating Treg was higher than in controls, whereas that of Tr1 cells was lower. In conclusion, although IL-10 concentration and Treg percentage were increased, their contribution to the natural history of metastatic NB appears uncertain.

    The objective of the study was to evaluate postoperative pain following a transcutaneous active conductive hearing implant. 27 patients undergoing Bonebridge (BB) bone conduction implantation were evaluated with two pain-related questionnaires. The Headache Impact Test (HIT-6) was used to measure the degree of disability including none or little impact (≤49), mild (50-55), moderate (56-59), and severe (≥60). The Brief Pain Inventory (BPI) was used to assess pain severity score and function interference (0 = no pain to 10 = worst pain); meaningful pain was considered to be ≥3. The impact of surgical factors on postoperative pain was analyzed. Postoperative BB pain results were compared with 11 Vibrant Soundbridge™ (VSB) and 103 cochlear implant (CI) users. The mean pre- and postoperative HIT-6 scores for BB implantation were 42.6 and 41.8, respectively and the mean preoperative BPI pain severity score changed from 0.6 to 0.9 postoperatively, whereas the preoperative interference score changed from 0.1 to 0.3. None of the mean postoperative values revealed significant pain. The retrosigmoid approach, the need for dural or sinus compression, and the use of bone conduction implant lifts had no significant impact on pain scores. The mean postoperative HIT-6 pain scores for patients with BB, VSB, and CI were 41.8, 46.4, and 42.8, respectively, with the differences not being significant. BB implantation causes no significant postoperative pain irrespective of sinus or dura compression. Pain scores were similar to those experienced by patients with other transcutaneous auditory implants such as middle ear or CIs.

  16. The diagnostic value of bone scintigraphy in patients with low back pain

    Schuette, H.E.; Park, W.M.

    1983-01-01

    Bone scintigraphy has been studied in two groups of patients presenting with low back pain. In one group of 38 patients suffering ''non-specific'' back pain, bone scintigraphy and laboratory findings were negative in 24. There were abnormal laboratory findings in all of the remaining 14 and 7 had positive bone scans indicative of clinically significant disease. Selection of patients for bone scintigraphy in this group should therefore be influenced by abnormal laboratory findings and elevation of the erythrocyte sedimentation rate in particular. By comparison, the bone scans were reviewed from another group of patients suffering previously known malignancy. Out of 138 patients, nearly 40% showed a positive bone scan due to subsequently proven metastasis. Bone scintigraphy was positive in a further 14% as a result of osteoporotic rib fracture and vertebral body collapse. In half of these, it was not possible to exclude malignancy by scintigraphy. The present findings indicate that bone scintigraphy is not a useful procedure in patients with long-standing low back pain who have normal radiographs and normal laboratory findings. (orig.)

    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.

    No effective treatment has been developed for bone-metastatic breast cancer. We found 3 cases with clinical complete response (cCR) of the bone metastasis and longer overall survival of the retrospectively examined cohort treated comprehensively including autologous formalin-fixed tumor vaccine (AFTV). AFTV was prepared individually for each patient from their own formalin-fixed and paraffin-embedded breast cancer tissues. Three patients maintained cCR status of the bone metastasis for 17 months or more. Rate of cCR for 1 year or more appeared to be 15% (3/20) after comprehensive treatments including AFTV. The median overall survival time (60.0 months) and the 3- to 8-year survival rates after diagnosis of bone metastasis were greater than those of historical control cohorts in Japan (1988-2002) and in the nationwide population-based cohort study of Denmark (1999-2007). Bone-metastatic breast cancer may be curable after comprehensive treatments including AFTV, although larger scale clinical trial is required.

    The number of patients suffering from postoperative pain due to orthopedic surgery and bone fracture is projected to dramatically increase because the human life span, weight, and involvement in high-activity sports continue to rise worldwide. Joint replacement or bone fracture frequently results in skeletal pain that needs to be adequately controlled for the patient to fully participate in needed physical rehabilitation. Currently, the 2 major therapies used to control skeletal pain are nonsteroidal anti-inflammatory drugs and opiates, both of which have significant unwanted side effects. To assess the efficacy of novel therapies, mouse models of orthopedic and fracture pain were developed and evaluated here. These models, orthopedic surgery pain and bone fracture pain, resulted in skeletal pain-related behaviors that lasted 3 weeks and 8 to 10 weeks, respectively. These skeletal pain behaviors included spontaneous and palpation-induced nocifensive behaviors, dynamic weight bearing, limb use, and voluntary mechanical loading of the injured hind limb. Administration of anti-nerve growth factor before orthopedic surgery or after bone fracture attenuated skeletal pain behaviors by 40% to 70% depending on the end point being assessed. These data suggest that nerve growth factor is involved in driving pain due to orthopedic surgery or bone fracture. These animal models may be useful in developing an understanding of the mechanisms that drive postoperative orthopedic and bone fracture pain and the development of novel therapies to treat these skeletal pains.

    Tumour metastasis is a complex process involving reciprocal interplay between cancer cells and host stroma at both primary and secondary sites, and is strongly influenced by microenvironmental factors such as hypoxia. Tumour-secreted proteins play a crucial role in these interactions and present...... morbidity and mortality. The molecular interactions governing the early events of osteolytic lesion formation are currently unclear.

    describing the extent of the surgical trauma were found to be associated with 30-day mortality. The 30-day mortality in patients undergoing surgery for MBD is highly dependent on the general health status of the patients as measured by the ASA score and the Karnofsky performance status. The extent of surgery...... of the surgery and thus the surgical trauma reduces survival in this patient group. We wanted to evaluate if perioperative parameters such as blood loss, extent of bone resection, and duration of surgery were risk factors for 30-day mortality in patients having surgery due to MBD in the appendicular skeleton.

    BACKGROUND Bisphosphonates are used to prevent the bone loss and fractures associated with osteoporosis, bone metastases, multiple myeloma, and osteogenis deformans. Distal limb fractures cause regional bone loss with cutaneous inflammation and pain in the injured limb that can develop into complex regional pain syndrome (CRPS). Clinical trials have reported that anti-resorptive bisphosphonates can prevent fracture-induced bone loss, inhibit serum inflammatory cytokine levels, and alleviate CRPS pain. Previously we observed that the inhibition of inflammatory cytokines or adaptive immune responses attenuated the development of pain behavior in a rat fracture model of CRPS and we hypothesized that bisphosphonates could prevent pain behavior, trabecular bone loss, post-fracture cutaneous cytokine up-regulation, and adaptive immune responses in this CRPS model. METHODS Rats underwent tibia fracture and cast immobilization for 4 weeks and were chronically administered either subcutaneously perfused alendronate or oral zoledronate. Behavioral measurements included hindpaw von Frey allodynia, unweighting, warmth, and edema. Bone microarchitecture was measured by uCT and bone cellular activity was evaluated by static and dynamic histomorphometry. Spinal cord Fos immunostaining was performed and skin cytokine (TNF, IL-1, IL-6) and nerve growth factor (NGF) levels were determined by EIA. Skin and sciatic nerve immunoglobulin levels were determined by EIA. RESULTS Tibia fracture rats developed hindpaw allodynia, unweighting, warmth, and edema, increased spinal Fos expression, trabecular bone loss in the lumbar vertebra and bilateral distal femurs as measured by uCT, increased trabecular bone resorption and osteoclast surface with decreased bone formation rates, increased cutaneous inflammatory cytokine and NGF expression and elevated immunocomplex deposition in skin and nerve. Alendronate (60 μg/kg/day s.c.) or zoledronate (3 mg/kg/day p.o.) treatment for 28 days, started

    Increasing numbers of patients with advanced cancer are receiving anticancer and/or palliative treatment in outpatient settings, and palliative care for outpatients with advanced cancer is being recognized as one of the most important areas for comprehensive cancer treatment. The aim of this study was to evaluate pain intensity, quality of life, quality of palliative care, and satisfaction reported by outpatients with advanced cancer. Questionnaires were sent to 1493 consecutive outpatients with metastatic or recurrent cancer from four regions in Japan; 859 responses were analyzed (58%). Questionnaires included the Brief Pain Inventory, Good Death Inventory, Care Evaluation Scale, and a six-point satisfaction scale. Approximately 20% of the patients reported moderate to severe pain. Whereas more than 70% agreed or strongly agreed with "good relationship with medical staff" and "being respected as an individual," less than 60% agreed or strongly agreed with "free from physical distress," "free from emotional distress," "maintaining hope," and "fulfillment at life's completion"; 54% reported some agreement with "feel a burden to others." About 20% reported that improvement is necessary in physical care by physicians, physical care by nurses, psycho-existential care, help with decision making, and coordination/consistency of care; 13% reported some levels of dissatisfaction. A considerable number of outpatients with metastatic or recurrent cancer experienced pain, physical symptoms, emotional distress, and existential suffering, and advocated improvements in palliative care across multiple areas.

    In clinic, local radiation is effective for relief of pain from cancer invasion into the bones. This effect is usually observed before the regression of tumor occurs, which implies radiation-induced pain relief by mechanisms other than tumor irradication. In this study, possible mechanisms were explored in animal model system. To establish an animal model, syngeneic hepatocarcinoma, HCa-I was transplanted on femoral periosteum of C3H/HeJ male mice and bone-invasive tumor growth was identified through the histological analysis. Development of tumor-induced pain was assessed by von Frey filament test, acetone test, and radiant heat test. Animals were also irradiated for their tumors. Any change in pain was analyzed by above tests for the quantitative change and by immunohistochemical stain for the expression of molecules such as c-fos, substance P, and calcitonin gene-related peptide (CGRP) in lumbar spinal cord. Cancer invasion into the bone was started from 7th day after transplantation and became evident at day 14. Objective increase of pain in the ipsilateral thigh was observed at day 14 on von Frey filament test and acetone test, while there was no remarkable regression of the tumors. In this model system, local radiation of tumor resulted in decrease in objective pain on von Frey filament test and acetone test. In the immunohistochemical stain for lumbar spinal cord, the expression of substance P and CGRP but not c-fos increased in tumor-bearing animal compared to the control. The expression of these molecules decreased in animals given local radiation. In summary, an animal model system was established for objective pain from cancer invasion into the bones. Local radiation of tumor induced objective pain relief and this effect seems to be mediated not by tumor regression but through altered production of pain-related molecules

    The information content of knee bone scintigraphy was evaluated, including pattern, localisation and intensity of retention relative to radiographic features of knee osteoarthritis, knee alignment and knee symptoms. A total of 308 knees (159 subjects) with symptomatic and radiographic knee osteoarthritis of at least one knee was assessed by late-phase (99m)Technetium methylene disphosphonate bone scintigraph, fixed-flexion knee radiograph, full limb radiograph for knee alignment and for self-reported knee symptom severity. Generalised linear models were used to control for within-subject correlation of knee data. The compartmental localisation (medial vs lateral) and intensity of knee bone scan retention were associated with the pattern (varus vs valgus) (p<0.001) and severity (p<0.001) of knee malalignment and localisation and severity of radiographic osteoarthritis (p<0.001). Bone scan agent retention in the tibiofemoral, but not patellofemoral, compartment was associated with severity of knee symptoms (p<0.001) and persisted after adjusting for radiographic osteoarthritis (p<0.001). To the authors' knowledge, this is the first study describing a relationship between knee malalignment, joint symptom severity and compartment-specific abnormalities by bone scintigraphy. This work demonstrates that bone scintigraphy is a sensitive and quantitative indicator of symptomatic knee osteoarthritis. Used selectively, bone scintigraphy is a dynamic imaging modality that holds great promise as a clinical trial screening tool and outcome measure.

    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. 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. 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. The pain relief began between 2 and 16 days post injection and the duration of pain palliation was in the range of 4 to 32 weeks (mean±SD=15.22±7.8). 64.3% of patients showed complete relief of pain and 21.4% achieved partial response to therapy. (Over all response to therapy was 85.7%). The lowest amount of peripheral blood cells was detected in the fourth week for RBCs and in the 6th week for WBCs and PLTs. No

    A 70-year-old man was diagnosed as thyroid medullary carcinoma with multiple bone metastases. He underwent total thyroidectomy and cervical lymph node dissection. After one year, the pain from his bone lesions was becoming severe. To relieve the pain, he was administered opioids and external-beam radiation therapy. However, he continued to have substantial multiple bone pain. We used combination therapy of strontium-89 chloride for the treatment of widespread multiple bone pain and external-beam radiation therapy for localized pain. That combination therapy was effective and improved the quality of life (QOL) of the patient. We used strontium-89 chloride four times within one year, and no serious side effects occurred during therapy. Our thoroughly investigated case suggests that strontium-89 therapy is one of the effective and safe therapies for patients with painful bone metastases of thyroid medullary carcinoma. (author)

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

    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

    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.

    Systemic use of radiopharmaceuticals is a recognized alternative method for the treatment of pain in patients with multiple bone metastasis. A new option, 188 Re-HEDP is proposed, using generator-obtained 188 Rhenium (β energy = 2.1 MeV, γ 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

    136 patients with bone cancer pain were treated with 153 Sm-EDTMP (ethylenediamine-tetramethylene phosphonic acid). Pain free was noted in 49 cases (36%, 49/136) and pain relief in 77 cases (56.6%, 77/136), the total relief rate being 92.6%(126/136). The data from 76 patients with moderate and severe pain showed there were no significant relationships between the patients' age, the dose of 153 Sm-EDTMP and the analgesic effects (P>0.05). The pain relief observed in the patients with chest pain (ribs metastases) was earlier than that in other groups (P 153 Sm-EDTMP is safe for use

    The aim of our study is to assess the diagnostic value of Technituim-(99m)-Methyle diphosphonate ((99m)Tc-MDP) Bone scintigraphy in the assessment of children with back pain. Included in this retrospective study were 68 child referred to us complaining of back pain (mean age of 13+ 2). There were 45 boys and 23 girls. All children have been investigated with conventional x-ray which revealed normal or inconclusive result. All underwent bone scintigraphy after the injection of (99m)Tc-MDP with calculated doses according to there body weights. Bone scintigraphy revealed 17 (25%) abnormal scans in 11 boys and 6 girls. Scans findings were suggestive of spondylolysis (n=4); malignancy including primary tumors and metastases (n=3); infection including osteomyelitis and discitis (n=3); sacroiliitis (n=2); benign tumors (n=2); pseudo fractures in ribs (n=1); necrosis in femoral head epiphysis(n=1) and nonskeletal-renal retention due to hydronephrosis (n=1). Sensitivity, specificity and accuracy of bone scan in detecting gross skeletal abnormality as a cause for back pain were 94% and 100% and 99% respectively. Bone isotope scan is a sensitive imaging modality in the assessment of pediatric patients with back pain. It is a reliable modality to detect and role out most benign and aggressive serious etiologies.

    Hyperalgesia in different musculoskeletal structures including bones is a major clinical problem. An experimental bone hyperalgesia model was developed in the present study. Hyperalgesia was induced by three different weights impacted on the shinbone in 16 healthy male and female subjects. The mechanical impact pain threshold (IPT) was measured as the height from which three weights (165, 330, and 660 g) should be dropped to elicit pain at the shinbone. Temporal summation of pain to repeated impact stimuli was assessed. All these stimuli caused bone hyperalgesia. The pressure pain threshold (PPT) was assessed by a computerized pressure algometer using two different probes (1.0 and 0.5 cm(2)). All parameters were recorded before (0), 24, 72, and 96 h after the initial stimulations. The IPTs were lowest 24 h after hyperalgesia induction for all three weights and the effect lasted up to 72 h (p pain and hyperalgesia model may provide the basis for studying this fundamental mechanism of bone-related hyperalgesia and be used for profiling compounds developed for this target.

    Pain can significantly decrease the quality of life of patients with advanced cancer. Current treatment strategies often provide inadequate analgesia and unacceptable side effects. Animal models of bone cancer pain are used in the development of novel pharmacological approaches. Here we conducted a systematic review and meta-analysis of publications describing in vivo modelling of bone cancer pain in which behavioural, general health, macroscopic, histological, biochemical, or electrophysiological outcomes were reported and compared to appropriate controls. In all, 150 publications met our inclusion criteria, describing 38 different models of bone cancer pain. Reported methodological quality was low; only 31% of publications reported blinded assessment of outcome, and 11% reported random allocation to group. No publication reported a sample size calculation. Studies that reported measures to reduce bias reported smaller differences in behavioural outcomes between tumour-bearing and control animals, and studies that presented a statement regarding a conflict of interest reported larger differences in behavioural outcomes. Larger differences in behavioural outcomes were reported in female animals, when cancer cells were injected into either the tibia or femur, and when MatLyLu prostate or Lewis Lung cancer cells were used. Mechanical-evoked pain behaviours were most commonly reported; however, the largest difference was observed in spontaneous pain behaviours. In the spinal cord astrocyte activation and increased levels of Substance P receptor internalisation, c-Fos, dynorphin, tumor necrosis factor-α and interleukin-1β have been reported in bone cancer pain models, suggesting several potential therapeutic targets. However, the translational impact of animal models on clinical pain research could be enhanced by improving methodological quality. Copyright © 2013. Published by Elsevier B.V.

    Objective: Bone scintigraphy with SPECT of the lumbar spine allows identification of lesions not seen with planar imaging, in patients with chronic low back pain. The aim of this study was to investigate the value of SPECT bone scans in diagnosis of patients with zygapophyseal joint pain. Methods: Thirty-five consecutive patients in Ruijin hospital from July 2006 to March 2007 with low back pain were en- rolled. All patients underwent bone scintigraphy with SPECT. According to the results of SPECT, patients with isotope-uptake joints received injections at the levels where abnormalities were identified on the scan. Patients with negative scans received other treatment (conservative treatment or surgery) but not facet joint injection. Clinical records were collected at 1-, 3-, and 6-month in SPECT-positive group after their initial treatment. And the SPECT-negative group were followed up at 6-month after therapy. Statistical analysis was performed with SPSS 10.0. Patients with SPECT-positive and -negative results were performed with the grouped t-test. Visual analog scales (VAS) were with the paired t-test used in patients with positive scans at before and after treatment. Results: Fifteen cases had facetal uptake of isotope on SPECT bone scans. After facet joint injection, 85.7% patients (12/14, 1 patient was excluded for operation) had improvement in pain score at 1-month, 78.6% (11/14) at 3-month, and 50.0% (7/14) at 6-month. Of 20 negative cases, 3 were treated by surgery and 17 by conservative treatment. All 20 cases were followed up for 6 months and 70.0% (14/20) had long time pain relief. Conclusion: SPECT bone scans are helpful to identify patients with low back pain who would benefit from facet joint injections. (authors)

    Diagnosis of wrist pain can be difficult to determine with clinical examination and conventional imaging techniques alone. Bone SPECT-CT (single-photon emission tomography with computerized tomography) is a hybrid imaging technique that overlays functional bone scintigraphy in tomographic/3D mode with conventional CT. Data from the two modalities are complementary; areas of abnormal bone metabolism can be localized with anatomical precision, hitherto lacking in conventional bone scans, while structural information from the CT scan further embellishes the diagnostic information. Over the last 6 years, one surgeon (David Evans) has used bone SPECT and later bone SPECT-CT as an additional line of investigation. This is a series of 21 consecutive patients with wrist pain that could not be diagnostically resolved with the usual combination of history, examination, and conventional imaging, and therefore underwent bone SPECT-CT. Clinical and imaging findings, management, and outcomes of these cases are discussed to explore the potential role of this hybrid functional modality in hand and wrist surgical practice.

    The purpose of this study was to assess the necessity of post-marketing safety monitoring focused on osteonecrosis of the jaw (ONJ) in patients with bone metastatic cancer treated with denosumab (AMG162). The ONJ safety data from three randomized phase III trials were pooled, and risk ratios and power were computed using traditional methods and simulation. A total of 89 ONJ cases (1.57%; 95% CI, 1.26-1.92) were reported with 52 (1.83%; 95% CI, 1.37-2.39) occurring in the denosumab group (n = 2,841) and 37 (1.30%; 95% CI, 0.92-1.79) in the zoledronic acid group (n = 2,836). Overall, the pooled risk ratio (RR) for ONJ was 1.40 (95% CI, 0.92-2.13; p = 0.11). In the trials reporting superior therapeutic efficacy of denosumab, the RR for ONJ was 1.61 (95% CI, 0.99-2.62; p = 0.052). However, neither separately nor pooled had any trial adequate power (>80%) to detect excess relative risks of ONJ of up to 76%, assuming fixed ONJ rates in the control arms. The joint power of the trials to detect the observed excess relative risk of 40% was only 36%. The rate of mucosal healing in patients with ONJ appeared similar in both groups (RR, 1.28; 95% CI, 0.66-2.45; p = 0.5). Although the overall frequency of ONJ was low, post-marketing risk-benefit studies with this novel compound appear warranted focusing specifically on this rare toxicity, which can potentially have a high impact on quality of life.

    Full text: Low back pain following minimal trauma may be caused by insufficiency fracture of the sacrum, which is often radiographically occult. Bone scintigraphy is a method of reference for the diagnosis; the results have been analyzed retrospectively. Bone scintigraphy was done on 228 patients treated by the departments of orthopedics at the General Hospital Linz. Predominantly after (minor) trauma, they suffered from lower back pain and their conventional radiographic findings were negative. During a 24 month period, a sacral insufficiency fracture was diagnosed in 68 patients (29,8 %). H-shaped hyperfixation of the tracer - described as typical - was present in only 12 % of the gases. Tracer accumulation was found as follows: located uni/bilateral in the sacral wings (39 % / 9 %), horizontal (31 %) and half H-shaped (9 %). In the majority of the gases bone scan detected farther fractures with main localization in the pubic bones, in the spine and the ribs. The insufficiency fracture of the sacrum as cause of lower back pain is not uncommon, especially in postmenopausal women with risk factors. Bone scintigraphy is not only an adequate procedure for the detection of often radiographically occult sacral fractures, but also an easy method to reveal the often concomitand fractures. (author)

    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.

    Cancer in bone is frequently a result of metastases from distant sites, particularly from the breast, lung, and prostate. Pain is a common and often severe pathological feature of cancers in bone, and is a significant impediment to the maintenance of quality of life of patients living with bone metastases. Cancer cell lines have been demonstrated to release significant amounts of the neurotransmitter and cell-signalling molecule l-glutamate via the system xC(-) cystine/glutamate antiporter. We have developed a novel mouse model of breast cancer bone metastases to investigate the impact of inhibiting cancer cell glutamate transporters on nociceptive behaviour. Immunodeficient mice were inoculated intrafemorally with the human breast adenocarcinoma cell line MDA-MB-231, then treated 14days later via mini-osmotic pumps inserted intraperitoneally with sulfasalazine, (S)-4-carboxyphenylglycine, or vehicle. Both sulfasalazine and (S)-4-carboxyphenylglycine attenuated in vitro cancer cell glutamate release in a dose-dependent manner via the system xC(-) transporter. Animals treated with sulfasalazine displayed reduced nociceptive behaviours and an extended time until the onset of behavioural evidence of pain. Animals treated with a lower dose of (S)-4-carboxyphenylglycine did not display this reduction in nociceptive behaviour. These results suggest that a reduction in glutamate secretion from cancers in bone with the system xC(-) inhibitor sulfasalazine may provide some benefit for treating the often severe and intractable pain associated with bone metastases.

    Prostate, breast and lung cancers readily develop bone metastases which lead to fractures, hypercalcemia and pain. Malignant growth in the bones depends on osteoclast-mediated bone resorption and in this regard bisphosphonate compounds, which have high-bone affinity and inhibit osteoclast activity......, have been found to alleviate bone cancer symptoms. In this study, the bisphosphonate risedronate and its phosphonocarboxylate derivative NE-10790 was tested in a murine bone cancer pain model. Risedronate decreased bone cancer-related bone destruction and pain-related behavior and decreased the spinal...

    Full Text Available Background: Despite advances in the knowledge of pathophysiology of pain and its management, patients continue to suffer from pain in many terminal stage cancer. Tramadol hydrochloride is a weak opioid with analgesic properties, and can be tried for cancer pain management. Objectives: This study was performed to find out the efficacy of the analgesic property of Tramadol through epidural route in cancer patients as an combination with low dose(.125% Bupivacaine and to compare with Fentanyl, a μ opioid agonist. Methods: 50 Cancer patients with or without previous pain management were randomly allocated to one of the two study regime- Group-A (tramadol 50 mg and Group-B (Fentanyl 50 mgm in combination with .125% Bupivacaine. Drugs were administered epidurally 6 hourly, 8 hourly and 12 hourly respectively for the 1st, 2nd and 3rd day. Low dose bupivacaine was added to both groups to enhance quality. Pain scores, blood pressure, respiratory rate, heart rate, side effects and patients' satisfaction score was recorded 6 hourly for 72 hrs. The data yielded from this study were compiled and analyzed by unpaired and paired ‘t' test with 95% confidence limit. A value of P< 0.05 was considered to be significant. ÷ square test was done for some of the data. Results: Pain scores were significantly decreased in both the groups but were not significantly different. The incidence of side effects including nausea and vomiting was found in both the groups and was not significantly different between the two groups. Conclusion: The use of epidural Tramadol in selected cancer pain patients (especially pain in lower abdomen and lower back may be very useful and is comparable to opioid in certain situations.

    2001-01-01

    Whereas in developing countries P-32 is widely used for radionuclide therapy of painful bone metastases, in Europe three radionuclides or radiopharmaceutical agents are available for pain palliation: Sr-89, Sm-153-EDTMP, and Re-186-HEDP. Radionuclide therapy for pain palliation is indicated for bone pain due to metastatic malignancy that has involved multiple skeletal sites and has evoked an osteoblastic response on bone scintigraphy. Response rates of about 70-80% in patients with breast or prostate cancer is reported in the literature, less in metastatic lesions of other primary malignancies. Sm-153-EDTMP may also be used for curative treatment of primary bone tumours or their metastases. Radiosynovectomy as therapeutic procedure or rheumatoid arthritis, other inflammatory joint diseases, persistent synovial perfusion, and other joint diseases is widely used. Using Y-90 for the knee joint, Re-186 for middle sized joints, and Er-169 for small joints an improvement of symptoms may be observed in about 70-80%. (author)

    Experiences with the new palliative agent Lu-177 EDTMP are summarized. The production of primary 177 Lu by the 176 Lu(n,γ) 177 Lu reaction and the synthesis of the radioactive complex are described as well as the procedures used for the control of the radionuclidic and the radiochemical purity. The stability of the compound has been also studied. The in vivo essays with rats and the use of the radiopharmaceutical, after a careful dose evaluation, in a patient with bone metastases from a breast cancer, show that the behaviour of Lu-177 EDTMP is similar to that of the analogue Sm-153 EDTMP.

    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

    Mesenchymal stem cells (MSCs) transplantation has been used for therapeutic applications in various diseases. Here we report MSCs can malignantly transform in vivo. The novel neoplasm was found on the tail of female rat after injection with male rat bone marrow-derived MSCs (rBM-MSCs) and the new tumor cell line, K3, was isolated from the neoplasm. The K3 cells expressed surface antigens and pluripotent genes similar to those of rBM-MSCs and presented tumor cell features. Moreover, the K3 cells contained side population cells (SP) like cancer stem cells (CSCs), which might contribute to K3 heterogeneity and tumorigenic capacity. To investigate the metastatic potential of K3 cells, we established the nude mouse models of liver and lung metastases and isolated the corresponding metastatic cell lines K3-F4 and K3-B6. Both K3-F4 and K3-B6 cell lines with higher metastatic potential acquired more mesenchymal and stemness-related features. Epithelial-mesenchymal transition is a potential mechanism of K3-F4 and K3-B6 formation.

    A 50-yr-old man arrived at our department for a rehabilitation prescription after a right knee medial collateral ligament sprain. Magnetic resonance imaging showed medial collateral ligament partial rupture and medial femoral condyle increased signal intensity indicating bone edema. After treatment, the patient still complained of weight-bearing knee medial compartment pain. A lateral wedged insole was prescribed to decrease medial compartment compression forces. Initial response to insole use was good, but soon after, the patient complained of severe worsening knee pain. On examination, the lateral joint line and condyle palpation were tender. Insole use discontinuation was recommended, and another magnetic resonance imaging scan was performed. It showed an high T2-weighted signal intensity, representing bone marrow edema comprising a volume of 5 x 5 x 4.5 cm of lateral femoral condyle. Discontinuation of orthosis use relieved the pain, and the edema disappeared. To our knowledge, lateral femoral condyle painful bone marrow edema after lateral wedged insole use has not been previously described. The findings of this case report indicate that lateral wedged insole prescription should be carefully evaluated.

    Cancer patients with bone metastases have previously been excluded from participation in physical activity programmes due to concerns of skeletal fractures. Our aim was to provide initial information on the association between physical activity levels and physical and mental health outcomes in prostate cancer patients with bone metastases. Between 2012 and 2015, 55 prostate cancer patients (mean age 69.7 ± 8.3; BMI 28.6 ± 4.0) with bone metastases (58.2% >2 regions affected) undertook assessments for self-reported physical activity, physical and mental health outcomes (SF-36), objective physical performance measures and body composition by DXA. Sixteen men (29%) met the current aerobic exercise guidelines for cancer survivors, while 39 (71%) reported lower aerobic exercise levels. Men not meeting aerobic exercise guidelines had lower physical functioning (p = .004), role functioning (physical and emotional) (p health scores (p = .014) as well all lower measures of physical performance (p exercise are associated with reduced physical and mental health outcomes in prostate cancer patients with bone metastases. While previous research has focused primarily in those with non-metastatic disease, our initial results suggest that higher levels of aerobic exercise may preserve physical and mental health outcomes in prostate cancer patients with bone metastases.

    The objective of this study was to correlate chronic medial knee pain at rest and during exercise with bone scintigraphic uptake, bone marrow edema pattern (BMEP), cartilage lesions, meniscal tears, and collateral ligament pathologies on magnetic resonance MR imaging (MRI). Fifty consecutive patients with chronic medial knee pain seen at our institute were included in our study. Pain level at rest and during exercise was assessed using a visual analog scale (VAS). On MR images, BMEP volume was measured, and the integrity of femoro-tibial cartilage, medial meniscus, and medial collateral ligament (MCL) were assessed. Semiquantitative scintigraphic tracer uptake was measured. Multivariate linear regression analysis was performed. At the day of examination, 40 patients reported medial knee pain at rest, 49 when climbing stairs (at rest mean VAS 33 mm, range 0-80 mm; climbing stairs mean VAS, 60 mm, range 20-100 mm). Bone scintigraphy showed increased tracer uptake in 36 patients (uptake factor, average 3.7, range 2.4-18.0). MRI showed BMEP in 31 studies (mean volume, 4,070 mm 3 ; range, 1,200-39,200 mm 3 ). All patients with BMEP had abnormal bone scintigraphy. Ten percent of patients with pain at rest and 8% of patients with pain during exercise showed no BMEP but tracer uptake in scintigraphy. Tracer uptake and signal change around MCL predicted pain at rest significantly (tracer uptake p=0.004; MCL signal changes p=0.002). Only MCL signal changes predicted pain during exercise significantly (p=0.001). In chronic medial knee pain, increased tracer uptake in bone scintigraphy is more sensitive for medial knee pain than BMEP on MRI. Pain levels at rest and during exercise correlate with signal changes in and around the MCL. (orig.)

Twenty patients were considered randomly for treatment with 153Sm-EDTMP and with 177Lu-EDTMP in 10 patients, respectively. Using fixed dose of 37.0 MBq/kg body weight of each, the mean administered doses of 153Sm-EDTMP and 177Lu-EDTMP were 2,155.2 ± 419.6 MBq (1,347–2,857 and 1,935.1 ± 559.4 MBq (1,073–2,627, respectively. Anterior and posterior whole body images were acquired at different time points following radioactivity administration. The first data set of pre-void images (acquired at 0.5 h representing the total activity of either of 153Sm-EDTMP or 177Lu-EDTMP was considered as reference images. All the serial images were used for patients’ dosimetry analysis by using organ level internal dosimetry assessment algorithm. Reduction in pain scoring was assessed clinically over 8 weeks by using appropriate WHO criteria and correlated with the absorbed dose to the metastatic sites.ResultsA total of 86 metastatic lesions clearly visualized on post-therapy serial images (matching on bone scans were evaluated for absorbed dose calculations. Both 153Sm-EDTMP and 177Lu-EDTMP delivered similar absorbed dose to the metastatic sites, i.e., 6.22 ± 4.21 and 6.92 ± 3.92 mSv/MBq, respectively. The mean absorbed doses to various other organs were found to be comparable and within the safe limits. A complete response (CR for each radionuclide was evaluated as 80.0%. No significant alternation in blood parameters and no untoward reaction were observed. However, a mild to severe toxicity was observed in two patients (1 each with 153Sm-EDTMP and 177Lu-EDTMP.

    This Study describes the method for preparation of labelling compound Ethylene diamine tetramethylene phosphonic acid (EDTMP) with 90 Y. Malignant cancer is one of the most important resulting in human death. Bone metastases in nearly 25% of all cancer patients; so it is useful to develop radiopharmaceuticals for the treatment of bone cancer. Yttrium-90 is high energy (2.3 MeV) beta emitter required with a physical haft life of 2.7 days which has limited bone-seeking properties. Its physical properties make it ideal for therapeutic application, the most energetic beta emission being able to penetrate to 1 cm from the site of deposition in soft tissue with an average range of approximately 4 mm. Theoretically, therefore, it can penetrate all marrow spaces in normal trabecular bone and conceivably even to the centre of large tumours where bone destruction may be extensive. Specific deposition of 90 Y into the skeleton demands its delivery in a chemical form with affinity for bone mineral alone. Compounds with these properties are the phosphonate analogues of polyaminocarboxylic acids, and one in particular EDTMP (ethylen diamine tetra methylene phosphonate) has already been used to target 153 Sm to bone mineral with success. Because of chemical similarities between 90 Y and the rare earths, EDTMP should form stable complexes with 90 Y and carry it specifically to the bone with comparable efficiency. Skeletal uptake of β - emitting radionuclides may be used for bone pain palliation or myeloablation. The physical characteristics of the β - particles required for the two conditions are, however, different, that is, higher energies are favorable for destruction of bone marrow. (author)

    The purpose of this investigation is to assess statistically the effect of different schemes of radiation therapy in patients with painful bone metastases: 2 x 8.5 Gy, 10 x 3 Gy, 5 x 4 Gy, 4 x 5 Gy, 5 Gy and 8 Gy and the reasons for their choice. In the investigation are included 523 patients - 71 % were with cancer of the breast, 16 % with lung cancer and 13% with other locations, 65 % (340) were women and 35 % (183) were men. They were randomized in different groups according to the radiation scheme as follows: 2 x 8.5 Gy - 392 patients, 10 x 3 Gy - 31 patients, 5 x 4 Gy - 43 patients, 4 x 5 Gy - 39 patients, 5 Gy - 9 patients and 8 Gy - 9 patients. In the group 2 x 8.5 Gy the measurement of pain relief was done after the first fraction, after the second fraction and a month later. In the other schemes the pain relief was measured after radiation treatment and 1 month later. The assessment of pain intensity was done after the WHO scale. The statistical processing of data was done as nonparametric analyses using SPSS-10 version with defining χ 2 and p=0.001. All versions of radiation therapeutic regimens relieved pain in different degree in each patient. Except data for bone metastases it was also important the general condition of the patient in combination with age for the choice of radiation treatment schedule. All radiation treatment schedules are effective in relieving pain in cancer patients with bone metastases and they have to be used adequately and competently by the radiation oncologist

    Increased participation in sports by the general public has led to an increase in sports-induced injuries, including stress fractures, shin splints, arthritis, and a host of musculotendinous maladies. Bone scintigraphy with Tc-99m MDP has been used with increasing frequency in detecting stress fractures, but this study can miss certain important conditions and detect other lesions of lesser clinical significance. This paper demonstrates the spectrum of findings on bone scanning in nonacute sports trauma and offers suggestions for the optimal use of Tc-99m MDP for detecting the causes of lower extremity pain in athletes

    We investigated the potential for improvement in disease control by use of autologous peripheral blood stem cell transplant (PBSCT) to permit administration of high activities of {sup 186}Re-hydroxyethylidene diphosphonate (HEDP) in patients with progressive hormone-refractory prostate cancer (HRPC). Eligible patients had progressive HRPC metastatic to bone, good performance status and minimal soft tissue disease. Patients received 5,000 MBq of {sup 186}Re-HEDP i.v., followed 14 days later by PBSCT. Response was assessed using PSA, survival, pain scores and quality of life. Thirty-eight patients with a median age of 67 years (range 50-77) and a median PSA of 57 ng/ml (range 4-3,628) received a median activity of 4,978 MBq {sup 186}Re-HEDP (range 4,770-5,100 MBq). The most serious toxicity was short-lived grade 3 thrombocytopenia in 8 (21%) patients. The median survival of the group is 21 months (95%CI 18-24 months) with Kaplan-Meier estimated 1- and 2-year survival rates of 83% and 40% respectively. Thirty-one patients (81%, 95% CI 66-90%) had stable or reduced PSA levels 3 months post therapy while 11 (29%, 95% CI 15-49%) had PSA reductions of >50% lasting >4 weeks. Quality of life measures were stable or improved in 27 (66%) at 3 months. We have shown that it is feasible and safe to deliver high-activity radioisotope therapy with PBSCT to men with metastatic HRPC. Response rates and survival data are encouraging; however, further research is needed to define optimal role of this treatment approach. (orig.)

    Conclusion: PCSD1 cells reproducibly induced bone loss leading to osteolytic lesions at the ends of the femur, and, in contrast, induced aberrant bone formation leading to osteoblastic lesions along the femur shaft. Therefore, the interaction of PCSD1 cells with different bone region-specific microenvironments specified the type of bone lesion. Our approach can be used to determine if different bone regions support more therapy resistant tumor growth, thus, requiring novel treatments.

    Full text: Pain is an extremely prevalent symptom in patients with cancer. Tumor size location of the lesion, stage of the disease is directly related to pain. Several studies have established that more than two third of cancer patients develop pain as a direct result of neoplasm. Bone metastases occur in more than 50% of breast and prostate cancer patients. Chronic pain relief is the goal of the treatments, which is tried to be achieved with narcotic analgesics, external beam radiotherapy and internal radiotherapy. This report describes the results of 153 Ethylenediaminetetramethylene phosphonate (EDTMP) in patients having multiple skeletal metastases from prostate and breast cancer in Paraguay. We report thirty male patients of prostate cancer and twenty female patients of breast cancer in ages between 59 and 73 years having multiple skeletal metastases. They were administered 100 mCi of 153Sm-EDTMP. Post-therapy imaging was done 2hrs. later under a large filed of view scintillation camera coupled with low energy all purpose (LEAP) parallel hole collimator. Good correlation was seen between this scan and the bone scan done earlier with 20 MCi of 99Tc-MDP. Most of the patients showed disappearance of pain one week after the treatment. Minimal decrease in platelets count that recovered within two weeks was also noted. Analgesic medication was suspended 3 weeks post treatment. In conclusion, our experience shows that palliative therapy with 153Sm-EDTMP gives good pain relief in patients with bony metastases in one or two weeks time and this procedure can be routinely employed for relief of pain relief.

    The purpose of this study is to evaluate the pain relief obtained by radiation therapy for painful bone metastases, with a special regard to general condition. Between June 1998 and May 2000, 54 patients with 86 painful bone metastases were treated with radiation therapy whose effects could be evaluated for a minimum period of 6 months or until death. Treatment schedules were 3 Gy/fraction/day (30-36 Gy/10-12 fractions) in usual cases (61 lesions), 4-8 Gy/fraction/day (8-20 Gy/1-5 fractions) in patients with a poor general condition (9 lesions), and 2 Gy/fraction/day (40-50 Gy/20-25 fractions) in lesions with a large radiation field (16 lesions). Complete pain relief without medication (CR) was achieved in 40 lesions (47%). Significant predictors for CR were primary site (p=0.0003), performance status (p=0.0060), pain score (p=00190), narcotic score (p<0.0001), and prognosis (p<0.0001), but no difference was found in CR among treatment schedules. No evidence of severe radiation-induced complication was seen. General condition (performance status and prognosis) has an influence on pain relief. Compared with the daily 2 Gy protocol, the daily 3 Gy protocol has the advantage of shorter treatment time. The treatment schedule should be assessed in patients with a large radiation field and/or poor general condition. Especially for the patients with poor general condition, combined pain medication should be considered. (author)

    Although the pathological changes in osteoporotic bones are well established, the characterization of the osteoporotic pain and its appropriate treatment are not fully elucidated. We investigated the behavioral signs of cutaneous and deep musculoskeletal pain and physical function; time-dependent changes in bone mineral density (BMD) and the emergence of the behavioral phenotype; and the effects of pharmacological interventions having different mechanisms of action (chronic intraperitoneal administration of pamidronate [0.25 mg/kg, 5x/week for 5 weeks] versus acute treatment with intraperitoneal morphine [10 mg/kg] and pregabalin [100 mg/kg]) in a mouse model of ovariectomized or sham-operated mice 6 months following surgery. We observed reduced BMD associated with weight gain, referred cutaneous hypersensitivity, and deep musculoskeletal pain that persisted for 6 months. Chronic bisphosphonate treatment, 6 months after ovariectomy, reversed bone loss and hypersensitivity to cold, but other behavioral indices of osteoporotic pain were unchanged. While the efficacy of acute morphine on cutaneous pain was weak, pregabalin was highly effective; deep musculoskeletal pain was intractable. In conclusion, the reversal of bone loss alone is insufficient to manage pain in chronic osteoporosis. Additional treatments, both pharmacological and nonpharmacological, should be implemented to improve quality of life for osteoporosis patients. PMID:28299231

    Background: Multimorbidity and declining performance in elderly cancer patients may result in less treatment benefit. We investigated whether age is a predictor for pain response and quality of life (QoL) after radiotherapy in patients with painful bone metastases. Methods: The database of the Dutch Bone Metastasis Study was used (1996–1999). 1157 patients, irradiated for painful bone metastases, rated their pain, QoL-domains and overall health at baseline and during follow-up. Response was calculated taking into account changes in pain score and medication. Patients were grouped into three age cohorts: A: <65 (n = 520), B: 65–74 (n = 410) and C: ⩾75 years (n = 227). Results: No significant difference existed in pain response between cohorts: 78% in cohort A, 74% in B and 67% in C. When assessing baseline QoL, a significant difference in activity level was noticed, with more impairment in elderly compared to younger patients (C versus B (p = 0.01), C versus A (p < 0.001)). Other QoL-domains were similar at baseline and during follow-up among cohorts. A pain response was significantly associated with improvement of health-related QoL (OR 3.74, 95% CI 2.66–5.25). Conclusion: The majority of elderly patients with painful bone metastases responded to radiotherapy and showed comparable overall QoL compared to their younger counterparts. Age is not a predictor for pain response or QoL

    Purpose: To determine the incidence of pain flare following radiotherapy (RT) for painful bone metastases. Materials and Methods: Patients with bone metastases treated with RT were eligible. Worst pain scores and analgesic consumption were collected before, daily during, and for 10 days after treatment. Pain flare was defined as a 2-point increase in the worst pain score (0-10) compared to baseline with no decrease in analgesic intake, or a 25% increase in analgesic intake with no decrease in worst pain score. Pain flare was distinguished from progression of pain by requiring the worst pain score and analgesic intake return to baseline levels after the increase/flare (within the 10-day follow-up period). Results: A total of 111 patients from three cancer centers were evaluable. There were 50 male and 61 female patients with a median age of 62 years (range, 40-89 years). The primary cancers were mainly breast, lung, and prostate. Most patients received a single 8 Gy (64%) or 20 Gy in five fractions (25%). The overall pain flare incidence was 44/111 (40%) during RT and within 10 days following the completion of RT. Patients treated with a single 8 Gy reported a pain flare incidence of 39% (27/70) and, with multiple fractions, 41% (17/41). Conclusion: More than one third of the enrolled patients experienced a pain flare. Identifying at-risk individuals and managing potential pain flares is crucial to achieve an optimal level of care.

    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.

    Bone metastasis are very common in many cancers; metastatic bone disease is the most common cause of cancer pain and also of serious complications, which reduce the quality of life of these patients. Management of skeletal cancer involves a multimodality approach who include bisphosphonates, which in association with anti-tumour treatments reduce the apparition of new skeletal-related events (SRE) and prolong the delay to first SRE. They although reduce the pain of bone metastasis. All this facts do the quality of life better.

    Bone metastases are common in patients with non-small cell lung cancer (NSCLC), often causing pain and a decrease in quality of life (QoL). The effect of bone-targeted agents is evaluated by reduction in skeletal-related events in which neither pain nor QoL are included. Radioisotopes can be administered for more diffuse bone pain that is not eligible for palliative radiotherapy. The evidence that bone-targeted agents relieve pain or improve QoL is not solid. We performed a systematic review of the effect of bone-targeted agents on pain and QoL in patients with NSCLC. Our systematic literature search included original articles or abstracts reporting on bisphosphonates, denosumab, or radioisotopes or combinations thereof in patients with bone metastases (≥5 patients with NSCLC), with pain, QoL, or both serving as the primary or secondary end point. Of the twenty-five eligible studies, 13 examined bisphosphonates (one also examined denosumab) and 12 dealt with radioisotopes. None of the randomized studies on bisphosphonates or denosumab evaluated pain and QoL as the primary end point. In the single-arm studies of bisphosphonates a decrease in pain or analgesic consumption was found for 38% to 77% of patients. QoL was included in five of 13 studies, but improvement was found in only two. No high-level evidence that bisphosphonates or denosumab reduce pain or improve QoL was found. Although the data are limited, radioisotopes seem to reduce pain with a rapid onset of action and duration of response of 1 to 3 months. The evidence that bisphosphonates or denosumab reduce or prevent pain in patients with NSCLC and bone metastases or that they have an influence on QoL is very weak. Radioisotopes can be used to reduce diffuse pain, although there is no high-level evidence supporting such use. Copyright © 2015 International Association for the Study of Lung Cancer.

    2014-01-01

    Background and purpose: An objective measure of pain relief may add important information to patients’ self assessment, particularly after a treatment. The study aims were to determine whether measures of physical activity and/or gait can be used in characterizing cancer-induced bone pain (CIBP) and whether these biomarkers are sensitive to treatment response, in patients receiving radiotherapy (XRT) for CIBP. Materials and methods: Patients were assessed before (baseline) and 6–8 weeks after XRT (follow up). The following assessments were done: Brief Pain Inventory (BPI), activPAL™ activity meter, and GAITRite® electronic walkway (measure of gait). Wilcoxon, Mann–Whitney and Pearson statistical analyses were done. Results: Sixty patients were assessed at baseline; median worst pain was 7 and walking interference was 5. At follow up 42 patients were assessed. BPI worst pain, average pain, walking interference and total functional interference all improved (p < 0.001). An improvement in functional interference correlated with aspects of physical activity (daily hours standing r = 0.469, p = 0.002) and gait (cadence r = 0.341, p = 0.03). The activPAL and GAITRite parameters did not change following XRT (p > 0.05). In responder analyses there were no differences in activPAL and GAITRite parameters (p > 0.05). Conclusion: Assessment of physical activity and gait allow a characterization of the functional aspects of CIBP, but not in the evaluation of XRT

    Mr. R.N. 32 year's old, high level sportsman, without particular pathological antecedents, consults for pains of the area above the knee of the left thigh, of mechanical pace being exacerbated with the effort. The clinical examination notes pains induced by the deep of the left thigh. The biological assessment, in particular blood cell formula and CRP were normal. The standard radiography of the femurs did not find an anomaly of the osseous structure. Because of the persistence of the pains, an osseous scintiscan was carried out and orientated towards pathology of soft tissues. The doppler and the TDM made it possible to pose the diagnosis of intra-tissues muscular hemangioma. The early times of the bone scintigraphy appears important in the approach diagnosis of many osseous disease of the sportsman. (author)

  18. Antinociceptive Effect of Intrathecal Microencapsulated Human Pheochromocytoma Cell in a Rat Model of Bone Cancer Pain

    2014-07-01

    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.

    Full Text Available Aim: The bone scintigraphy is indicated in patients with costochondral pain in order to identify the organic etiology. We aimed to investigate the local and projecting pain, or incidental findings in the three phase bone scintigraphy of the patients referred for costochondral pain. Methods: We included 50 patients (36F, 24M; mean: 41±18 years-old referred to our department for three phase bone scintigraphy for costochondral pain between January 2009-July 2012. Results: Among the 50 patients 22 had normal scintigraphy. An increased activity accumulation in the sternoclavicular joint was observed in 12 patients (right in 4, left in 4 and bilateral in 4 only in late phase and in 9 patients (right in 2, left in 1 and bilateral in 6 with increased vascularity. Among projecting pain causes, activity was present on sternum in 4 patients, on humerus in 2 patients and on the first costae in 2 patients. For the characterization of inflammatory pathology, the three phase bone scintigraphy showed sensitivity, specificity, accuracy, positive and negative predictive values of 43%, 94%, 78%, 77% and 78% respectively. Conclusion: Bone scintigraphy is an effective diagnostic method for the identification of local or projecting pain, and additionally unexpected incidental pathologies associated with costochondral pain. However regarding the characterization of inflammatory process false negatives should be considered.

    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

    Radiotherapy has a good effect in palliation of painful bone metastases, with a pain response rate of more than 60%. However, shortly after treatment, in approximately 40% of patients a temporary pain flare occurs, which is defined as a two-point increase of the worst pain score on an 11-point rating scale compared to baseline, without a decrease in analgesic intake, or a 25% increase in analgesic intake without a decrease in worst pain score, compared to baseline. A pain flare has a negative impact on daily functioning and mood of patients. It is thought to be caused by periostial edema after radiotherapy. Dexamethasone might diminish this edema and thereby reduce the incidence of pain flare. Two non-randomized studies suggest that dexamethasone reduces the incidence of a pain flare by 50%. The aim of this trial is to study the effectiveness of dexamethasone to prevent a pain flare after palliative radiotherapy for painful bone metastases and to determine the optimal dose schedule. This study is a three-armed, double-blind, placebo-controlled multicenter trial. We aim to include 411 patients with uncomplicated painful bone metastases from any type of primary solid tumor who receive short schedule radiotherapy (all conventional treatment schedules from one to six fractions). Arm 1 consists of daily placebo for four days, arm 2 starts with 8 mg dexamethasone before the (first) radiotherapy and three days placebo thereafter. Arm 3 consists of four days 8 mg dexamethasone. The primary endpoint is the occurrence of a pain flare. Secondary endpoints are pain, quality of life and side-effects of dexamethasone versus placebo. Patients complete a questionnaire (Brief Pain Inventory with two added questions about side-effects of medication, the EORTC QLQ-C15-PAL and QLQ-BM22 for quality of life) at baseline, daily for two weeks and lastly at four weeks. This study will show whether dexamethasone is effective in preventing a pain flare after palliative radiotherapy for

      After an anterior cruciate ligament (ACL) injury, a majority of patients have a traumatic bone marrow lesion (BML, or bone bruise). The clinical relevance of posttraumatic lesions remains unclear.   To explore the cross-sectional associations between traumatic BML volume and self-reported knee pain and symptoms among individuals within 4 weeks of ACL injury.   Cross-sectional exploratory analysis of a randomized clinical trial.   Orthopaedic departments at 2 hospitals in Sweden.   As part of a randomized trial (knee anterior cruciate ligament nonoperative versus operative treatment [KANON] study), 121 young active adults (74% men, age = 26 ± 5 years, height = 1.8 ± 0.1 m, weight = 76 ± 13 kg) with an ACL tear were studied.   The BML volume in the proximal tibia and distal femur was segmented using magnetic resonance images obtained within 4 weeks of injury. A radiologist evaluated the presence of depression fractures on the images. Pain and symptoms of the injured knee (Knee Injury and Osteoarthritis Outcome Score [KOOS] pain and symptoms subscales) were obtained the same day as imaging. We used linear regression models to assess the associations.   Most knees had at least 1 BML (96%), and the majority (57%) had a depression fracture. Whole-knee BML volume was not related to knee pain for the entire cohort (β = -0.09, P = .25). Among those without a depression fracture, larger whole-knee BML volume was associated with increased knee pain (β = -0.46, P = .02), whereas no association was found for those with a depression fracture (β = 0.0, P = .96). Larger medial (β = -0.48, P = .02) but not lateral (β = -0.03, P = .77) tibiofemoral BML volume was associated with greater pain. We found no association between BML volume and knee symptoms.   We confirmed the absence of relationships between whole-knee BML volume and pain and symptoms within 4 weeks of ACL injury. Our findings extend previous reports in identifying weak associations between

    Fifteen bone scintigrams in patients with diffuse bone metastases were reviewed because of the diffuse radionuclide accumulation in the axial skeleton. Diagnoses were gastric cancer in 6 patients, prostatic cancer in 5, breast cancer in 3, and renal pelvic tumor in one. In 5 patients with gastric cancer, one with prostatic cancer, and one with renal pelvic tumor, initial bone scintigraphy showed diffuse accumulation. In one gastric cancer patient and two breast cancer patients, the multiple bone metastases had altered the diffuse bone metastasis. All patients had no lung or liver metastasis morphologically at the course of diagnosed diffuse bone metastasis. Overall, the diffuse bone metastases were classified into two groups: diffuse symmetrical accumulation in proportion to bone marrow demonstrated in the gastric cancer, and diffuse accumulation centering the axial skeleton with asymmetrical accumulation in the rib and extremities demonstrated in cancer of the prostate. The finding of X ray films were consistent to common bone metastases in proportion to the primary tumor. Diffuse bone metastases did not show the characteristic finding. During the period from the diagnosed time to the death of patients, the patients with gastric cancer died extremely earlier in comparison to the patients with breast cancer and with prostatic cancer.

    Calcineurin inhibitor-induced pain syndrome is an entity recognized in patients on immunosuppressive therapy after transplantation. Diagnosis is characterized by onset of pain beginning in the setting of an elevated calcineurin-inhibitor trough level. Reducing the medication dose relieves symptoms. Imaging findings can be nonspecific, including bone marrow edema and periosteal reaction. We present the unique case of calcineurin inhibitor-induced pain syndrome in a child and review the imaging findings. (orig.)

    Oral metastatic tumors are rare. A case of primary affection of oral soft tissues by metastatic hypernefroma, without radiologic evidence of bone involvement, is presented in this paper. Review of the literature reveals that the gingiva is the commonest location of metastatic hypernephroma in the oral soft tissues. The most important clinicopathology and therapeutic features are also reviewed.

    This retrospective study evaluated the efficacy and toxicity of 89 strontium chloride (Metastron - Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of the treatment according to extension of bone involvement, moderate or extensive. The predictive value of Flare response for antalgic efficacy was also studied. Grade III/IV leuko-thrombopenia was observed after only 5% of injections. An improvement of the quality of life was obtained in 65% of cases, a decrease of pain in 78% (31% complete response) and reduction of antalgic intake in 60%. Efficacy was significantly better for pain decrease (p=0,005) and reduction of antalgic intake (p=0,018), and response duration was significantly longer (p 89 strontium chloride for treatment of metastatic bone pain and suggest that internal radiotherapy should be started earlier. A bone scan could be proposed at the time of hormonal escape and bone pain, and internal radiotherapy could be initiated when several metastatic foci exist, even if only one is painful. Thus, pain-free follow up could be prolonged, and transition to other therapeutic approaches, particularly opioids, delayed. (author)

    To assess the safety and effectiveness of combined radiofrequency (RF) ablation and cementoplasty in the treatment of painful neoplastic lesions of bone. The authors performed a retrospective analysis of 25 combined treatments comprising RF ablation followed by injection of polymethylmethacrylate cement performed in 19 patients during a 22-month period. Patients ranged in age from 42 to 82 years (mean, 58.9 years) and included five women and 14 men. Eleven vertebrae (eight lumbar and three thoracic), nine acetabulae, three sacra, one pubis, and one humerus were treated with a total of 36 RF ablations (in several instances, overlapping ablations were used). The location of the primary neoplasm, lesion size, pain before and after the procedure (as determined with a 10-point visual analog scale [VAS]), number of RF treatments, type of device used for cementoplasty, RF time, cement volume, and extravasation were documented. A total of 25 combined RF ablations and cementoplasties were performed. The technical success rate was 100% (25 of 25 treatments). There were seven minor complications: six limited cement extravasations and a transient thermal nerve injury. The mean RF time was 9.1 minutes (range, 6-12 minutes). The mean cement volume injected was 6.1 mL (range, 0.8-16 mL). The mean preprocedure pain (as measured with a VAS) was 7.9 (range, 7.0-9.0) and the mean posttreatment pain was 4.2 (range, 0-6); the difference was statistically significant (mean score, 4.08; 95% confidence interval: 3.92, 4.87; P < .0001) using a paired t test. Combined RF ablation and cementoplasty appears to be safe and effective in the treatment of painful neoplastic lesions of bone.

    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

    Traumatic bone fractures cause moderate to severe pain, which needs to be minimized for optimal recovery and animal welfare, illustrating the need for reliable objective pain biomarkers for use in a clinical setting. The objectives of this study were to investigate catestatin (CST) and vasostatin (VS) concentrations as two new potential biomarkers, and cortisol concentrations, scores of the short form of the Glasgow composite measure pain scale (CMPS-SF), and visual analog scale (VAS) in dogs suffering from traumatic bone fractures before and after morphine administration in comparison with healthy dogs. Fourteen dogs with hind limb or pelvic fractures and thirty healthy dogs were included. Dogs with fractures were divided into four groups according to analgesia received before participation. Physical examination, CMPS-SF, pain and stress behavior VAS scores were recorded in all dogs. Saliva and blood were collected once in healthy dogs and in dogs with fractures before and 35-70 min after morphine administration. Blood samples were analyzed for CST, VS, and cortisol. Saliva volumes, however, were insufficient for analysis. Catestatin and cortisol concentrations, and CMPS-SF, and VAS scores differed significantly between dogs with fractures prior to morphine administration and healthy dogs. After morphine administration, dogs with fractures had significantly decreased CMPS-SF and VAS scores and, compared to healthy dogs, CST concentrations, CMPS-SF, and VAS scores still differed significantly. However, CST concentrations remained largely within the normal range. Absolute delta values for CST significantly correlated with delta values for CMPS-SF. Catestatin and cortisol did not differ significantly before and after morphine administration. Vasostatin concentrations did not differ significantly between groups. Catestatin and cortisol concentrations, CMPS-SF, and VAS scores differed significantly in the dogs with traumatic bone fractures compared to the healthy dogs

    Objective: To explore the correlationship between SPECT radionuclide bone scan and serum levels of three tumor markers as well as three cytokines in patients with breast cancer. Methods: Serum levels of IL-1β, IL-6, IL-8, CEA, CA15-3(with RIA) and PRL(with CLIA) were determined in 1)20 breast cancer patients with definite bone metastatic lesions shown on radio-nuclide bone scan 2) 20 breast cancer patients without bone metastasis 3) 30 patients with benign breast disorders and 4) 35 controls. Results: The serum tumor markers levels in patients osseous metastasis were significantly higher than those in the other three groups (P 0.05). The serum levels of IL-6, IL-8, IL-1β in patients with osseous metastasis were also significantly higher than those in other groups(P<0.05). Conclusion: Over expression of CEA, CA15-3 and PRL as well as IL-6, IL-8, IL-1β were related with osseous metastasis from breast cancer. Determination of the levels of these six parameters would be helpful for dynamic monitoring of the extent of metastasis. (authors)

    Cancer and its treatment are stressful and reduce the quality of life in children. The aim of this study was to investigate the effect of massage therapy on pain and anxiety arising from intrathecal therapy or bone marrow aspiration in children with cancer. We conducted a controlled pretest/posttest quasi-experimental study at a paediatric oncology unit in Turkey. Twenty-five children were enrolled in this study. Their pain and anxiety were determined using a visual analogue scale. When the pretest and posttest pain and anxiety levels of the groups were compared, no statistically significant difference was found (P > 0.05). It was determined that pain and anxiety levels in the experimental group decreased significantly. This study provides preliminary evidence for the effectiveness in children of massage in reducing pain and anxiety arising from intrathecal therapy or bone marrow aspiration. © 2014 Wiley Publishing Asia Pty Ltd.

    In addition of clinical evaluation and x-ray radiography, the diagnosis of a loose joint prosthesis is often made by nuclear medicine imaging techniques. Differentiation between loosening and infected prosthesis is important for better treatment of those patients. Aim: The aim of this study was to reevaluate the scintigraphic patterns in patients with painful hip of knee arthroplasty. Material and Method: From 1996. to 2003. forty patients aged 49-78 years were referred for evaluation of possible loosening/infection joint prosthesis: 36 pts with 39 total/ partial hip prosthesis, 1 pt with knee prosthesis and 3 pts with history of previously extracted hip prosthesis due to infection. Whole body acquisition had been performed with a single head gamma camera three hours after the injection of 740 MBq 99m Tc-MDP. Scans were classified as: positive for loosening if abnormal uptake was shown at the tip of the prosthesis; positive for infection if diffuse abnormal uptake was shown around the implant; negative and indeterminate scans. Scintigraphic findings were compared to clinical follow up, histology or cultures. Results: Positive findings were found in 17 bone scans strongly suggesting loosening in 10 cases, infection of prosthesis in 4 cases and both loosening/infection in 3 cases. Bone scintigraphy was normal in 11pts. Scans of three pts with previously extracted hip prosthesis and scheduled for reimplatation, showed inhomogeneously and mildly increased uptake in femur. Most of scans classified as indeterminate (n=12) showed slightly increased tracer uptake in region of acetabular roof, greater or lesser tho chanter, suggesting bone remodeling due to the presence of implant, rather than loosening. Conclusion: 99m Tc-MDP bone scintigraphy had a significant role in assessing the painful joint prosthesis. Complementary diagnostic procedures should be considered in indeterminate scintiscans.

    Full Text Available Metastases to the spine can involve the bone, epidural space, leptomeninges, and spinal cord. The spine is the third most common site for metastatic disease, following the lung and the liver. Approximately 60–70% of patients with systemic cancer will have spinal metastasis. Materials/Methods. This is a review of the imaging techniques and typical imaging appearances of spinal metastatic disease. Conclusions. Awareness of the different manifestations of spinal metastatic disease is essential as the spine is the most common site of osseous metastatic disease. Imaging modalities have complimentary roles in the evaluation of spinal metastatic disease. CT best delineates osseous integrity, while MRI is better at assessing soft tissue involvement. Physiologic properties, particularly in treated disease, can be evaluated with other imaging modalities such as FDG PET and advanced MRI sequences. Imaging plays a fundamental role in not only diagnosis but also treatment planning of spinal metastatic disease.

    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.)

    Purpose: To determine the current patterns of practice in Japan and to investigate factors that may make clinicians reluctant to use single-fraction radiotherapy (SF-RT). Methods and Materials: Members of the Japanese Radiation Oncology Study Group (JROSG) completed an Internet-based survey and described the radiotherapy dose fractionation they would recommend for four hypothetical cases describing patients with painful bone metastasis (BM). Case 1 described a patient with an uncomplicated painful BM in a non-weight-bearing site from non-small-cell lung cancer. Case 2 investigated whether management for a case of uncomplicated spinal BM would be different from that in Case 1. Case 3 was identical with Case 2 except for the presence of neuropathic pain. Case 4 investigated the prescription for an uncomplicated painful BM secondary to oligometastatic breast cancer. Radiation oncologists who recommended multifraction radiotherapy (MF-RT) for Case 2 were asked to explain why they considered MF-RT superior to SF-RT. Results: A total of 52 radiation oncologists from 50 institutions (36% of JROSG institutions) responded. In all four cases, the most commonly prescribed regimen was 30 Gy in 10 fractions. SF-RT was recommended by 13% of respondents for Case 1, 6% for Case 2, 0% for Case 3, and 2% for Case 4. For Case 4, 29% of respondents prescribed a high-dose MF-RT regimen (e.g., 50 Gy in 25 fractions). The following factors were most often cited as reasons for preferring MF-RT: “time until first increase in pain” (85%), “incidence of spinal cord compression” (50%), and “incidence of pathologic fractures” (29%). Conclusions: Japanese radiation oncologists prefer a schedule of 30 Gy in 10 fractions and are less likely to recommend SF-RT. Most Japanese radiation oncologists regard MF-RT as superior to SF-RT, based primarily on the time until first increase in pain.

    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

    Rhenium-188-HEDP is a beta-emitting radiopharmaceutical used for palliation of metastatic bone pain. We investigated whether the addition of rhenium-188-HEDP to docetaxel/prednisone improved efficacy of chemotherapy in patients with CRPC. Patients with progressive CRPC and osteoblastic bone metastases were randomised for first-line docetaxel 75 mg/m{sup 2} 3-weekly plus prednisone with or without 2 injections of rhenium-188-HEDP after the third (40 MBq/kg) and after the sixth (20 MBq/kg) cycle of docetaxel. Primary endpoint was progression-free survival (PFS), defined as either PSA, radiographic or clinical progression. Patients were stratified by extent of bone metastases and hospital. Forty-two patients were randomised for standard treatment and 46 patients for combination therapy. Median number of cycles of docetaxel was 9 in the control group and 8 in the experimental group. Median follow-up was 18.4 months. Two patients from the experimental group did not start treatment after randomisation. In the intention to treat analysis no differences in PFS, survival and PSA became apparent between the two groups. In an exploratory per-protocol analysis median overall survival was significantly longer in the experimental group (33.8 months (95%CI 31.75-35.85)) than in the control group (21.0 months (95%CI 13.61-28.39); p 0.012). Also median PFS in patients with a baseline phosphatase >220U/L was significantly better with combination treatment (9.0 months (95%CI 3.92-14.08) versus 6.2 months (95%CI 3.08-9.32); log rank p 0.005). As expected, thrombocytopenia (grade I/II) was reported more frequently in the experimental group (25% versus 0%). Combined treatment with rhenium-188-HEDP and docetaxel did not prolong PFS in patients with CRPC. The observed survival benefit in the per-protocol analysis warrants further studies in the combined treatment of chemotherapy and radiopharmaceuticals. (orig.)

    Full Text Available We describe our semi-automatic segmentation of whole-body diffusion-weighted MRI (WBDWI using a Markov random field (MRF model to derive tumor total diffusion volume (tDV and associated global apparent diffusion coefficient (gADC; and demonstrate the feasibility of using these indices for assessing tumor burden and response to treatment in patients with bone metastases. WBDWI was performed on eleven patients diagnosed with bone metastases from breast and prostate cancers before and after anti-cancer therapies. Semi-automatic segmentation incorporating a MRF model was performed in all patients below the C4 vertebra by an experienced radiologist with over eight years of clinical experience in body DWI. Changes in tDV and gADC distributions were compared with overall response determined by all imaging, tumor markers and clinical findings at serial follow up. The segmentation technique was possible in all patients although erroneous volumes of interest were generated in one patient because of poor fat suppression in the pelvis, requiring manual correction. Responding patients showed a larger increase in gADC (median change = +0.18, range = -0.07 to +0.78 × 10(-3 mm2/s after treatment compared to non-responding patients (median change = -0.02, range = -0.10 to +0.05 × 10(-3 mm2/s, p = 0.05, Mann-Whitney test, whereas non-responding patients showed a significantly larger increase in tDV (median change = +26%, range = +3 to +284% compared to responding patients (median change = -50%, range = -85 to +27%, p = 0.02, Mann-Whitney test. Semi-automatic segmentation of WBDWI is feasible for metastatic bone disease in this pilot cohort of 11 patients, and could be used to quantify tumor total diffusion volume and median global ADC for assessing response to treatment.

    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 (pbone 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.

    Purpose: Multiple randomized controlled trials have demonstrated the equivalence of multifraction and single-fraction (SF) radiotherapy for the palliation of painful bone metastases (BM). However, according to previous surveys, SF schedules remain underused. The objectives of this study were to determine the current patterns of practice internationally and to investigate the factors influencing this practice. Methods and Materials: The members of three global radiation oncology professional organizations (American Society for Radiology Oncology [ASTRO], Canadian Association of Radiation Oncology [CARO], Royal Australian and New Zealand College of Radiologists) completed an Internet-based survey. The respondents described what radiotherapy dose fractionation they would recommend for 5 hypothetical cases describing patients with single or multiple painful BMs from breast, lung, or prostate cancer. Radiation oncologists rated the importance of patient, tumor, institution, and treatment factors, and descriptive statistics were compiled. The chi-square test was used for categorical variables and the Student t test for continuous variables. Logistic regression analysis identified predictors of the use of SF radiotherapy. Results: A total of 962 respondents, three-quarters ASTRO members, described 101 different dose schedules in common use (range, 3 Gy/1 fraction to 60 Gy/20 fractions). The median dose overall was 30 Gy/10 fractions. SF schedules were used the least often by ASTRO members practicing in the United States and most often by CARO members. Case, membership affiliation, country of training, location of practice, and practice type were independently predictive of the use of SF. The principal factors considered when prescribing were prognosis, risk of spinal cord compression, and performance status. Conclusion: Despite abundant evidence, most radiation oncologists continue to prescribe multifraction schedules for patients who fit the eligibility criteria of

    2000-01-01

    In February 1996 the Trans-Tasman Radiation Oncology Group (TROG) initiated a two-arm, multicentre, prospective randomized trial on radiotherapy for neuropathic pain due to bone metastases (TROG 96.05). This trial compares the response to a single 8-Gy fraction with 20 Gy in five fractions. The accrual target is 270 patients. In order to evaluate compliance with eligibility criteria after approximately 1 year of accrual, an independent audit of the first 42 randomized patients was commissioned. This found that only one of these patients did not have genuine neuropathic pain, but that this patient and seven others (19%) had infringements of other eligibility/exclusion criteria for the trial. Accordingly it was decided to continue the full audit up to 90 patients. This detected no further patients without genuine neuropathic pain, and found only one other eligibility infringement (1/48; 2%). It is concluded that this quality assurance (QA) measure undertaken early in the trial led to significantly improved clinician awareness of, and compliance with, eligibility/exclusion criteria. It also enabled an accurate comparison of outcome data for all randomized versus all eligible patients at the time of the preplanned first interim analysis at 90 patients. In view of the excellent compliance demonstrated in the second audit, a one-in-five sampling is proposed for future audits from centres that have already accrued at least five consecutive eligible patients. This is consistent with TROG QA guidelines now operational. Copyright (2000) Blackwell Science Pty Ltd

    The aim of this study was to evaluate the response and hematological toxicity in peptide receptor radionuclide therapy (PRRT) with lutetium ((177)Lu)-DOTA-octreotate (DOTATATE) in metastatic neuroendocrine tumor (NET) with extensive bone marrow metastasis at the initial diagnosis. A retrospective evaluation was undertaken for this purpose: Patients with NET with extensive diffuse bone marrow involvement at diagnosis who had received at least three cycles of PRRT with (177)Lu-DOTATATE were considered for the analysis. The selected patients were analyzed for the following: (i) Patient and lesional characteristics, (ii) associated metastatic burden, (iii) hematological parameters at diagnosis and during the course of therapy, (iv) response to PRRT (using a 3-parameter assessment: Symptomatic including Karnofsky/Lansky performance score, biochemical finding, and scan finding), (v) dual tracer imaging features [with somatostatin receptor imaging (SRI) and fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT)]. Based on the visual grading, tracer uptake in somatostatin receptor (SSTR)-positive bone marrow lesions were graded by a 4-point scale into four categories (0-III) in comparison with the hepatic uptake on the scan: 0 - no uptake; I - clear focus but less than liver uptake; II - equal to liver uptake; and III - higher than liver uptake]. Hematological toxicity was evaluated using National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 score. A total of five patients (age range: 26-62 years; three males and two females) with diffuse bone marrow involvement at the diagnosis was encountered following analysis of the entire patient population of 250 patients. Based on the site of the primary, three had thoracic NET (two patients bronchial carcinoid and one pulmonary NET) and two gastroenteropancreatic NET (one in the duodenum and one patient of unknown primary with liver metastasis).

    This retrospective study evaluated the toxicity and efficacy of strontium-89 chloride (Metastron, Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of treatment in patients with moderate and extensive bone involvement. The predictive value of flare response with regard to analgesic response was also studied. High-grade leukothrombopenians were observed after only 5% of injections. An improvement in quality of life was obtained in 65% of cases, a decrease in pain in 78% (31% complete response) and a reduction of analgesics in 60%. Efficacy was significantly better for pain decrease (P=0.005) and reduction of analgesics (P=0.018), and response was significantly longer (P 89 Sr chloride for the treatment of metastatic bone pain and suggest that internal radiotherapy should be started earlier. A bone scan could be proposed at the time of hormonal escape resulting in bone pain, and internal radiotherapy could be initiated when several metastatic foci exist, even if only one is painful. In this way, pain-free follow-up could be prolonged, and the transition to other therapeutic approaches, particularly opioids, delayed. (orig.)

    The aim of this study was to determine if it would be possible to use spinal bone single photon emission computed tomography (SPECT) in patients with unexplained back pain in varied clinical backgrounds and to determine if a positive or negative study had any prognostic value. The study was co-ordinated by the International Atomic Energy Agency (IAEA) and involved 8 centres in 7 countries. A total of 174 patients (mean age 42 years, range 15-80 years) were screened and found to have no obvious cause for their back pain at the time of the SPECT scan. All patients had a CT, and planar radiology. There was clinical follow-up data for 6 months without active treatment (such as surgery) in 147 patients. A panel of 9 specialists in nuclear medicine, radiology and orthopaedics reviewed all images and histories. Final assessment determined that 141 patients had skeletal causes for their back pain. SPECT was abnormal in 64% of these patients as compared to 58% with CT and 18% with planar radiology. CT was most likely to be diagnostic in disc degeneration (sensitivity 92%). SPECT was most diagnostic in facet joint disease (sensitivity 96%). In the 43 patients without any skeletal disease the specificity of SPECT was 79%, compared to 65% for CT. Follow-up of patients at 6 months showed that on average 71% had improvement of symptoms, suggesting a benign course for their back pain, with the exception of patients with pure facet joint disease, identified on SPECT but with no treatment. Spinal skeletal SPECT can be applied in a wide range of social and clinical settings. Results compare well with CT, providing additional information in 30% of patients, especially in facet joint disease where a positive SPECT study, suggests a worse clinical outcome at 6 months.

    Purpose: To determine the current patterns of practice in Japan and to investigate factors that may make clinicians reluctant to use single-fraction radiotherapy (SF-RT). Methods and Materials: Members of the Japanese Radiation Oncology Study Group (JROSG) completed an Internet-based survey and described the radiotherapy dose fractionation they would recommend for four hypothetical cases describing patients with painful bone metastasis (BM). Case 1 described a patient with an uncomplicated painful BM in a non-weight-bearing site from non-small-cell lung cancer. Case 2 investigated whether management for a case of uncomplicated spinal BM would be different from that in Case 1. Case 3 was identical with Case 2 except for the presence of neuropathic pain. Case 4 investigated the prescription for an uncomplicated painful BM secondary to oligometastatic breast cancer. Radiation oncologists who recommended multifraction radiotherapy (MF-RT) for Case 2 were asked to explain why they considered MF-RT superior to SF-RT. Results: A total of 52 radiation oncologists from 50 institutions (36% of JROSG institutions) responded. In all four cases, the most commonly prescribed regimen was 30 Gy in 10 fractions. SF-RT was recommended by 13% of respondents for Case 1, 6% for Case 2, 0% for Case 3, and 2% for Case 4. For Case 4, 29% of respondents prescribed a high-dose MF-RT regimen (e.g., 50 Gy in 25 fractions). The following factors were most often cited as reasons for preferring MF-RT: 'time until first increase in pain' (85%), 'incidence of spinal cord compression' (50%), and 'incidence of pathologic fractures' (29%). Conclusions: Japanese radiation oncologists prefer a schedule of 30 Gy in 10 fractions and are less likely to recommend SF-RT. Most Japanese radiation oncologists regard MF-RT as superior to SF-RT, based primarily on the time until first increase in pain.

    Bone morphogenetic protein-2 (BMP-2) is a pleiotropic, secreted molecule with diverse effects. The potent ability of BMP-2 to stimulate bone growth prompted its widespread clinical use for arthrodesis (spine fusion). However, elevated post-operative pain in patients treated with BMP-2 has been increasingly reported. Determining whether BMP-2 induces pain directly or whether it induces neuroinflammation, which could lower the threshold for pain, is important for developing therapeutic interventions. We therefore modeled the clinical use of BMP-2 for posterior lumbar fusion by implanting absorbable collagen sponges soaked with either recombinant human BMP-2 (rhBMP-2) or vehicle above the L4-L5 transverse processes of rat spine. Using microarray analysis we found that implantation of rhBMP-2-soaked absorbable collagen sponges resulted in altered expression of numerous pro-inflammatory genes in the adjacent dorsal root ganglia (DRG) showing that implantation of rhBMP-2/absorbable collagen sponges triggers potent neuroinflammatory responses in the DRG-2. Interestingly, direct BMP-2 treatment of DRG explants resulted in changes in gene expression that were not specifically pro-inflammatory. Rats implanted with rhBMP-2 in absorbable collagen sponges also exhibited a transient change in thermal and mechanical sensitivity indicating that rhBMP-2 applied to the lumbar spine could increase pain sensitivity. Immunohistochemical analysis indicated macrophage infiltration in the DRG and spinal nerve in rats implanted with rhBMP-2/absorbable collagen sponges or absorbable collagen sponges alone, but not in rats that underwent surgery without implantation of the absorbable collagen sponges suggesting that the sponges contributed to the biological response. Indeed, analysis of DRGs taken from rats implanted with absorbable collagen sponges without rhBMP-2 showed a significant change in gene expression distinct from DRGs from rats undergoing surgery only. Our data indicate that

    {sup 18}F-FDG PET/CT should be performed before a diagnostic biopsy site is chosen in patients with a high clinical suspicion of aggressive, advanced tumour. The aim of this study was to evaluate the safety and efficacy of {sup 18}F-FDG PET/CT in guiding biopsy of bone metastases in patients with advanced lung cancer. PET/CT-guided percutaneous core biopsies were performed in 51 consecutive patients with suspected lung cancer and {sup 18}F-FDG-avid bone lesions after whole-body {sup 18}F-FDG PET/CT scans. Generally, one tissue sample was obtained from each patient. The final diagnoses were established on the basis of the histology results. The histopathological and molecular testing results were systematically evaluated. A total of 53 samples were obtained for histological examination or molecular testing as a second biopsy was required in two patients in whom the pathological diagnosis was unclear following the first biopsy. The pathological diagnosis and lung cancer classification were confirmed in 48 patients. The epidermal growth factor receptor mutation status was determined in 23 biopsies, and the mutation rate was 30.4 % (7/23). The anaplastic lymphoma kinase mutation status was determined in 19 biopsies, and the mutation rate was 31.6 % (6/19). Two of the 51 biopsies were positive for non-Hodgkin's lymphoma and one was positive for metastatic renal cell carcinoma. The first-time diagnostic success rate of biopsy was 96.1 % (49/51) and the overall diagnostic success rate and sensitivity were 100 %. All 51 patients were eventually confirmed as having stage IV disease. No serious complications were encountered and the average biopsy time was 30 min. PET/CT-guided percutaneous biopsy of {sup 18}F-FDG-avid bone metastases is an effective and safe method that yields a high diagnostic success rate in the evaluation of hypermetabolic bone lesions in patients with suspected advanced lung cancer.

    Full Text Available The preferential metastasis of prostate cancer cells to bone disrupts the process of bone remodeling and results in lesions that cause significant pain and patient morbidity. Although prostate-specific antigen (PSA is an established biomarker in prostate cancer, it provides only limited information relating to bone metastases and the treatment of metastatic bone disease with bisphosphonates or novel noncytotoxic targeted or biological agents that may provide clinical benefits without affecting PSA levels. As bone metastases develop, factors derived from bone metabolism are released into blood and urine, including N- and C-terminal peptide fragments of type 1 collagen and bone-specific alkaline phosphatase, which represent potentially useful biomarkers for monitoring metastatic bone disease. A number of clinical trials have investigated these bone biomarkers with respect to their diagnostic, prognostic, and predictive values. Results suggest that higher levels of bone biomarkers are associated with an increased risk of skeletal-related events and/or death. As a result of these findings, bone biomarkers are now being increasingly used as study end points, particularly in studies investigating novel agents with putative bone effects. Data from prospective clinical trials are needed to validate the use of bone biomarkers and to confirm that marker levels provide additional information beyond traditional methods of response evaluation for patients with metastatic prostate cancer.

    2012-08-01

    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.

    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-1β 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-1β was significantly increased in caner pain rats while intrathecally administration of anti-HMGB1 could decrease IL-1β. Together with previous reports, we predict that bone cancer induces HMGB1 production, enhancing spinal IL-1β expression and thus modulating spinal excitatory synaptic transmission and pain response.

    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.

    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.

    The aim of this work was to obtain new bisphosphonate marked with 131I suitable for palliative treatment of bone metastases pain characteristics. Materials and Methods: It started with aromatic amino acids and the synthesis consisted of three stages: 1) Protection of amino groups by acetylation; 2) phosphonation protected amino acids with a mixture of phosphorous acid and phosphorus pentachloride; 3) Lack of protection of the amino groups by basic hydrolysis. The compounds obtained were characterized by IR, 1H NMR, RMN13-C mass. Los spectrometry bisphosphonic acids obtained were labeled with 131I using chloramine T and iodogen as oxidants. Stability of labeled compounds in aqueous solution was studied serum. 3 mg of 2-amino-3- (4-hydroxyphenyl) -1-hydroxypropyl-1,1-bisphosphonic acid labeled of 131I were administered to male wistar rats (170-190 g) through a lateral tail vein. The scintigraphic study was conducted at 2, 6 and 12 hours. Results: The yield of the reactions of the amino group protection four compounds ranged from 75 to 80%, while the phosphonation was between 50 and 60%. The radiochemical purity of 2-amino-3- (4-hydroxyphenyl) -1-hydroxypropyl-1,1- bisphosphonic acid labeled with 131I was (91.5 ± 1.4)% and its stability was satisfactory for 72h. Scintigraphic images suggest excretion by the kidneys of the compound and from 12 h post-administration begin to visualize bone structures of the animal, suggesting that the compound exhibits affinity for these tissues. Conclusions: A novel synthesis method with modifications that yielded the sodium salts of bisphosphonic acids starting from the respective aromatic amino acids was developed. 2-amino-3- (4-hydroxyphenyl) -1-hydroxypropyl-1,1-bisphosphonic acid 131I labeled was stable up to 72h and showed affinity for bone tissue.

    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.

    The purpose of this investigation was to find out a reliable scintigraphic method to investigate different fatigue phenomena in bone and to correlate the scintigraphic findings to the development of clinical symptoms. The gamma-imaging after the injection of bone seeking tracers is recommended to be performed after a period of 1-3 hours. The experiments indicate that in active bone tissue, might it be a healing fracture or a remodeling bone, the tracer uptake still increases after 1-3 hours. The delayed gamma-imaging can therefore be useful, especially if it is important to investigate faint physiological changes in bone tissue. It seems, that the capacity of emission energy in the diagnosis of bone affections is superior to the radiology because of its excellent histo-functional resolution especially in detecting and localizing bone affections

    The prognosis for patients with metastatic breast cancer remains poor. Metastatic breast cancer confined to the bones may have a better prognosis, especially hormone receptor-positive disease. We performed a prospective, randomized clinical trial to compare immediate consolidation with high-dose chemotherapy and hematopoietic support versus observation with high-dose consolidation at the time of disease progression in women with metastatic breast cancer and only bone metastases. The patients received chemotherapy with doxorubicin, 5-fluorouracil and methotrexate before randomization. In all, 85 patients were enrolled and 69 were randomized. The median follow-up is 8.1 years from randomization. The median event-free survival (EFS) for the immediate transplant arm is 12 months and for the observation arm is 4.3 months (Pconsolidation offers a clinically and statistically significant improvement in EFS compared with radiation therapy alone following induction chemotherapy for women with metastatic breast cancer confined to the bones.

    Full Text Available 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.

    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

    Bone metastases are a frequent complication of cancer. It is estimated that they arise in 14-70% of all tumour patients, while it was reported that they occur in 70-85% patients in autopsy material. Although they may arise from any primary malignant tumour, certain tumours such as breast, prostate, lung, thyroid, kidney and myeloma have a predilection for a spread to bone. Bone metastases frequently cause pain, but there are also clinical situations with bone metastases causing no pain at all. The overall importance of the problem of bone metastases is well recognized by the fact that each year hundreds of thousands of cancer patients develop bone metastases. For example, more than 100 000 new patients develop this condition in the United States of America, although the prevalence is estimated to be double the number of new cases. While it is virtually unknown how many cancer patients in the developing countries develop bone metastases, it is not unrealistic to expect that these figures largely surpass those coming from the developed countries. The reason is simply that more patients in the developing countries are diagnosed as having locally advanced or metastatic cancer that will eventually widely disseminate, including bone metastasis as well. Furthermore, at least some of the cancer patients may survive prolonged periods of time. They can also develop earlier and more severe symptoms than patients harbouring other types (locations) of metastases, emphasizing the importance of the overall problem of painful bone metastases. In addition, there is a big socioeconomic problem of bone metastasis, burdening health care systems worldwide, while having continuous adverse psychological effect on both patients and their families. The management of patients with metastatic bone pain must be a multidisciplinary approach and includes the use of analgesia, radiotherapy, surgery, chemotherapy, hormone treatment, radioisotopes and bisphosphonates.

    Autologous bone grafting is still considered the standard method for alveolar cleft repair. However, donor site morbidities remain a relevant problem in cleft care. Thus, the authors assessed postoperative donor site pain in cleft patients who underwent alveolar cleft repair by iliac crest bone graft transferring through a prospective randomized study comparing 2 minimally invasive harvesting techniques. Fifty-six consecutive patients with cleft lip and palate who underwent iliac crest bone grafting for alveolar cleft repair were randomly divided into 2 groups: bone graft harvested by minimally invasive techniques without (group 1) and with (group 2) periosteum elevation. Postoperative donor site pain was evaluated using a unidimensional numerical pain intensity rating scale (0, "no pain;" 10, "worst pain imaginable") at 1, 3, 6, 9, and 12 hours after the procedures and on the 3rd, 7th, 14th, 21st, and 28th days after surgeries. Intergroup comparisons were performed. The mean measurements of donor site pain revealed no significant differences (all P > 0.05) in any of the evaluated postoperative period comparisons between groups 1 and 2. There was a greater number (P < 0.05) of group 1 patients who reported "no pain" in the donor site compared with group 2, suggesting that periosteum elevation may play a role in pain intensity measurement. This prospective randomized study showed no difference in pain intensity among cleft patients who had postoperative pain. However, a greater number of patients in group 1 reported "no pain" in comparison to patients in group 2.

    Purpose: To study the course of quality of life (QoL) after radiation therapy for painful bone metastases. Patients and Methods: The Dutch Bone Metastasis Study randomized 1157 patients with painful bone metastases between a single fraction of 8 Gy and 6 fractions of 4 Gy between 1996 and 1998. The study showed a comparable pain response of 74%. Patients filled out weekly questionnaires for 13 weeks, then monthly for 2 years. In these analyses, physical, psychosocial, and functional QoL domain scores and a score of general health were studied. Mixed modeling was used to model the course of QoL and to study the influence of several characteristics. Results: In general, QoL stabilized after 1 month. Psychosocial QoL improved after treatment. The level of QoL remained stable, steeply deteriorating at the end of life. For most QoL domains, a high pain score and intake of opioids were associated with worse QoL, with small effect sizes (−0.11 to −0.27). A poor performance score was associated with worse functional QoL, with a medium effect size (0.41). There is no difference in QoL between patients receiving a single fraction of 8 Gy and 6 fractions of 4 Gy, except for a temporary worsening of physical QoL after 6 fractions. Conclusion: Although radiation therapy for painful bone metastases leads to a meaningful pain response, most domains of QoL do not improve after treatment. Only psychosocial QoL improves slightly after treatment. The level of QoL is related to the actual survival, with a rather stable course of QoL for most of the remaining survival time and afterward a sharp decrease, starting only a few weeks before the end of life. Six fractions of 4 Gy lead to a temporary worse physical QoL compared with a single fraction of 8 Gy.

    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.

    To date, high mortality in women due to malignancy breast cancer related to the metastasis to the bone is a significant challenge. As, magnetic nanoparticles (MNPs) conjugated with the biocompatible polymers was employed for the delivery of some hydrophobic anticancer agents, the main aim of the current research was to assess whether cisplatin-loaded MNPs enhanced the anticancer effect of free cisplatin in breast cancer cells. MNPs decorated with PEG were synthesized by an improved coprecipitation technique, and then cisplatin was loaded onto the MNPs via a simple mixing method. Afterward, its morphology, size, chemical structure, magnetic property, hydrodynamic diameter, zeta potential, and crystal structure were characterized by scanning and transmittance electron microscopy, Fourier transforms infrared spectroscopy, vibrating sample magnetometer, dynamic light scattering, and X-ray powder diffraction and flame atomic absorption spectroscopy respectively. Additionally, the effects of cisplatin and MNPs-PEG-cisplatin on viability, migration and adhesion capacity of T47D cells were investigated by evaluating α2-integrin and β1-integrin; mRNAs were assessed by real-time RT-PCR. Consequently, the in vitro assay results showed a considerable dose-dependent inhibitory effect of cisplatin and MNPs-PEG-cisplatin on proliferation, migration, and adhesion of T47D cells. Finally, current research was shown that MNPs-PEG-cisplatin strongly increased anticancer effects compared with free cisplatin in the T47D cell line. © 2017 John Wiley & Sons A/S.

    We compared the activity of denosumab with zoledronic acid for delaying or preventing hypercalcaemia of malignancy (HCM) in patients with advanced cancer and bone metastases or with multiple myeloma. Patient-level data were combined from two identically designed, randomised, double-blind, active-controlled, phase III trials of advanced cancer patients with breast cancer and other solid tumours (excluding breast or prostate cancer) or multiple myeloma. End-points included time to first on-study HCM, time to first and subsequent on-study HCM, proportion of patients experiencing HCM and proportion of patients experiencing recurrent HCM. Denosumab significantly delayed the time to first on-study HCM, representing a 37% reduction in the hazard ratio (HR) compared with zoledronic acid (HR, 0.63; 95% confidence interval (CI): 0.41-0.98; P = 0.042) and reduced the risk of developing recurrent HCM (time to first and subsequent on-study HCM) by 52% (rate ratio, 0.48; 95% CI: 0.29-0.81; P = 0.006). The median time on study was 12.9 months. Fewer patients receiving denosumab compared with zoledronic acid experienced an HCM event (1.7% versus 2.7%; P = 0.028). Of the 84 patients experiencing an HCM event, 40% of those receiving zoledronic acid experienced >1 event of HCM compared with 31% of those receiving denosumab. Denosumab treatment was more efficacious than treatment with zoledronic acid in delaying or preventing HCM in advanced cancer patients with breast cancer, other solid tumours or multiple myeloma.

Androgen ablation therapy can be used in treatment of these patients; however, most will progress to metastatic hormone-refractory prostate cancer. In this regard, docetaxel has been approved to treat metastatic hormone-refractory prostate cancer in the United States. In this study, we aimed to investigate the results of this treatment modality in metastatic prostate cancer patients from Iran. Methods:We evaluated PSA response and bone pain relief in 18 metastatic prostate cancer patients who underwent treatment with docetaxel at a dose of 75 mg/m2 intravenously on the first day of treatment. The treatment was repeated every three weeks (6 cycles along with 10 mg of prednisolone. Results: Of 18 patients, 39% had >50% decline in PSA levels.There were 16% of the patients with a PSA decline of approximately 30% to 50% of the pre-treatment levels. In addition, 29% of the patients had progressive PSA levels during chemotherapy. Among them, 55% had significant pain relief. Conclusion: This research showed the effectiveness of docetaxel to decrease PSA levels in metastatic hormone-refractory prostate cancer patients from Iran. Docetaxel was also valuable in alleviation of pain in these patients. However, prospective studies should validate this approach.

    Histoplasmosis is an infection caused by a fungus called Histoplasma. Diagnosis of histoplasmosis is based on the culture of biological samples and detection of fungus in tissues. Histoplasmosis can mimic malignant lesions. We report a 65-year-old, immunocompetent, male patient with back pain. We describe the main clinical and radiological characteristics in our patient who had vertebral histoplasmosis that mimicked cancer. A computed tomography scan showed lytic lesions of the right side of T4, T5, and T6 vertebral bodies. Magnetic resonance imaging displayed abnormal marrow signals in T4, T5, and T6 vertebral bodies (low signal on T1, high on T2 and short time inversion recovery (STIR)). Which was mimicking malignancy, such as haematological malignancy and metastatic bone cancer. Therefore, thoracic spinal surgery using the anterior approach was performed. An intraoperative frozen section examination and routine postoperative pathology showed thoracic histoplasmosis infection. Treatment of histoplasmosis was performed with oral itraconazole. The lesions did not progress and the patient symptomatically improved at a follow-up of 26 months.

    Rhenium-186(Sn)-1,1-hydroxyethylidene diphosphonate ( 186 Re-HEDP) has been used for palliation of metastatic bone pain. The purpose of this study was to find a relationship between the bone marrow absorbed dose and the toxicity, expressed as the percentage decrease in the peripheral blood platelet count. The bone marrow absorbed dose was calculated according to the MIRD model using data obtained from ten treatments of patients suffering from metastatic prostate cancer; noninvasive and pharmacokinetic method were used. The bone marrow doses were related to toxicity using the pharmacodynamic sigmoid E max model. The mean bone marrow absorbed doses using the noninvasive and pharmacokinetic methods were in a close range to each other (1.07 mGy/MBq and 1.02 mGy/MBq, respectively). There was a good relationship between the toxicity and the bone marrow absorbed dose (r = 0.80). Furthermore, the EDrm 50 (i.e., the bone marrow absorbed dose producing a 50% platelet decrease) to bone marrow for 186 Re-HEDP was on the order of 2 Gy. Although the function of normal bone marrow is affected by metastases in patients with metastatic bone disease, the MIRD model can be used to relate toxicity to the bone marrow absorbed dose after a therapeutic dosage of 186 Re-HEDP. 33 refs., 1 fig., 1 tab

    Complex regional pain syndrome (CRPS) is usually associated with trauma. Rarely, it may be seen in association with malignancies. We present here the bone scan and X-ray findings in the case of a 56-year-male-patient with adenocarcinoma lung who also had non-traumatic CRPS without involvement of the stellate ganglion. The case highlights the fact that spontaneous development of reflex sympathetic dystrophy may be associated with a neoplastic etiology. PMID:24019656

    Full Text Available Cancer-induced bone pain (CIBP is a frequent complication in patients suffering from bone metastases. Previous studies have demonstrated a pivotal role of reactive oxygen species (ROS in inflammatory and neuropathic pain, and ROS scavengers exhibited potent antinociceptive effect. However, the role of spinal ROS remains unclear. In this study, we investigated the analgesic effect of two ROS scavengers in a well-established CIBP model. Our results found that intraperitoneal injection of N-tert-Butyl-α-phenylnitrone (PBN, 50 and 100 mg/kg and 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl (Tempol, 100 and 200 mg/kg significantly suppressed the established mechanical allodynia in CIBP rats. Moreover, repeated injection of PBN and Tempol showed cumulative analgesic effect without tolerance. However, early treatment with PBN and Tempol failed to prevent the development of CIBP. Naive rats received repetitive injection of PBN and Tempol showed no significant change regarding the nociceptive responses. Finally, PBN and Tempol treatment notably suppressed the activation of spinal microglia in CIBP rats. In conclusion, ROS scavengers attenuated established CIBP by suppressing the activation of microglia in the spinal cord. Keywords: Cancer-induced bone pain, Reactive oxygen species, PBN, Tempol

    Tumor necrosis factor-α (TNF-α) is a proalgesic cytokine that is commonly expressed following tissue injury. TNF-α expression not only promotes inflammation but can also lead to pain hypersensitivity in nociceptors. With the established link between TNF-α and inflammatory pain, we identified its increased expression in the teeth of patients affected with caries and pulpitis. We generated a transgenic mouse model (TNF-α(glo)) that could be used to conditionally overexpress TNF-α. These mice were bred with a dentin matrix protein 1 (DMP1)-Cre line for overexpression of TNF-α in both the tooth pulp and bone to study oral pain that would result from subsequent development of pulpitis and bone loss. The resulting DMP1/TNF-α(glo) mice show inflammation in the tooth pulp that resembles pulpitis while also displaying periodontal bone loss. Inflammatory infiltrates and enlarged blood vessels were observed in the tooth pulp. Pulpitis and osteitis affected the nociceptive neurons innervating the orofacial region by causing increased expression of inflammatory cytokines within the trigeminal ganglia. With this new mouse model morphologically mimicking pulpitis and osteitis, we tested it for signs of oral pain with an oral function assay (dolognawmeter). This assay/device records the time required by a mouse to complete a discrete gnawing task. The duration of gnawing required by the DMP1/TNF-α(glo) mice to complete the task was greater than that for the controls; extended gnaw time in a dolognawmeter indicates reduced orofacial function. With the DMP1/TNF-α(glo) mice, we have shown that TNF-α expression alone can produce inflammation similar to pulpitis and osteitis and that this mouse model can be used to study dental inflammatory pain. © International & American Associations for Dental Research 2015.

    Breast cancer (BC) is the most common female cancer worldwide with approximately 10 % of new cases metastatic at diagnosis and 20-50 % of patients with early BC who will eventually develop metastatic disease. Bone is the most frequent site of colonisation and the development of skeletal metastases depends on a complex multistep process, from dissemination and survival of malignant cells into circulation to the actual homing and metastases formation inside bone. Disseminated tumor cells (DTCs) can be detected in bone marrow in approximately 30 % of BC patients, likely reflecting the presence of minimal residual disease that would eventually account for subsequent metastatic disease. Patients with bone marrow DTCs have poorer overall survival compared with patients without them. Although bone-only metastatic disease seems to have a rather indolent behavior compared to visceral disease, bone metastases can cause severe and debilitating effects, including pain, spinal cord compression, hypercalcemia and pathologic fractures. Delivering an appropriate treatment is therefore paramount and ideally it should require interdisciplinary care. Multiple options are currently available, from bisphosphonates to new drugs targeting RANK ligand and radiotherapy. In this review we describe the mechanisms underlying bone colonization and provide an update on existing systemic and locoregional treatments for bone metastases.

    Introduction: Radiation therapy has been shown to successfully palliate bone metastases. A number of systematic reviews and large clinical trials have reported response rates for initial treatment and retreatment. Objective: To determine overall response rates of patients with painful uncomplicated bone metastases undergoing initial treatment and retreatment. Methods: Intent-to-treat and evaluable patient statistics from a systematic review of palliative radiotherapy trials for initial treatment of bone metastases and a randomized clinical trial of retreatment were pooled and analyzed to determine the overall response rates for patients receiving initial treatment and retreatment. Results: In the intent-to-treat calculation, 71–73% of patients had an overall response to radiation treatment and in the evaluable patient population; 85–87% of patients did so. Response rates varied slightly whether patients underwent single or multiple fractions in initial treatment or retreatment. Conclusions: Single and multiple fraction radiation treatment yielded very similar overall response rates. Patients treated with a single fraction for both initial and repeat radiation experience almost identical overall response to those patients treated with multiple fraction treatment. It is therefore recommended that patients with uncomplicated painful bone metastases be treated with a single 8 Gy fraction of radiation at both the initial treatment and retreatment

    Myeloma bone disease (MBD) is a devastating complication of multiple myeloma that leads to severe pain. The aim of this study was to evaluate the efficacy and tolerability of tapentadol prolonged release (PR) in the management of patients with MBD suffering from moderate-to-severe cancer pain. 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. Of 25 patients, 22 completed the study. Pain intensity significantly decreased from baseline to all the week intervals (Popioid-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.

    Morphine is viewed as one of the classical treatments for intractable pain, but its role is limited by side effects, including analgesic tolerance. A few chemokines have been reported to be engaged in the mechanisms of morphine tolerance. However, the exact roles of CXC chemokine 11 (CXCL11) in chronic morphine tolerance remain unknown. In this study, Walker 256 mammary gland carcinoma cells were inoculated into the tibia of rats to provoke cancer-induced bone pain. Then, morphine was intrathecally administered twice daily for seven consecutive days to induce drug tolerance. We found that the level of CXCL11 in lumbar spinal cord was increased during the development of morphine tolerance in cancer-induced bone pain rats. Meanwhile, CXCL11 was co-localized with markers of astrocytes and neurons in the spinal cord. Inhibition of CXCL11 by neutralizing antibodies could remarkably attenuate the degree of morphine tolerance and decrease the activation of astrocytes. Moreover, blocking astrocyte activation by d, l-Fluorocitric acid could distinctly alleviate morphine tolerance and reduce the expression of CXCL11. Finally, morphine stimulation could induce the release of CXCL11 by cultured astrocytes and neurons in vitro. In summary, our results provide evidence that spinal CXCL11 plays a powerful modulatory role in the development of morphine tolerance through cross-talking between astrocytes and neurons.

    Rhenium-188 dimercaptosuccinic acid complex [{sup 188}Re(V)DMSA], a potential therapeutic analogue of the tumour imaging agent {sup 99m}Tc(V)DMSA, is selectively taken up in bone metastases in patients with prostate cancer. It would be helpful in planning palliative radionuclide therapy if {sup 99m}Tc(V)DMSA could be used to predict tumour and kidney retention of {sup 188}Re(V)DMSA. The aim of this study was to determine the correlation between tumour-to-normal tissue ratios and kidney-to-soft tissue ratios of {sup 99m}Tc(V)DMSA and {sup 188}Re(V)DMSA. This would determine whether a scan with {sup 99m}Tc(V)DMSA, could be used to identify patients for whom {sup 188}Re(V)DMSA treatment would be contra-indicated, and enable prediction of relative kidney and tumour radiation absorbed dose in {sup 188}Re(V)DMSA treatment. Ten patients with prostate carcinoma were recruited following observation of disseminated bone metastases on a recent {sup 99m}Tc-hydroxydiphosphonate bone scan. Whole-body planar scans were obtained at ca. 4 h and 24 h after hydration and injection of 600 MBq {sup 99m}Tc(V)DMSA, and a week later, at similar times after hydration and injection of 370 MBq {sup 188}Re(V)DMSA. A triple-energy window (TEW) scatter correction was applied to the {sup 188}Re scans. Counts per pixel were determined in regions of interest drawn over metastatic sites, kidneys and normal soft tissue. Tumour-to-soft tissue ratios were significantly lower (by a factor of approximately 0.8 after the TEW was applied) on {sup 188}Re scans than on {sup 99m}Tc scans, but the two were highly linearly correlated both in all individual patients and in tumours pooled from all patients together both at 4 h and at 24 h. Kidney-to-soft tissue ratios were similarly correlated and were lower for {sup 188}Re than for {sup 99m}Tc by a similar factor. Both tumour- and kidney-to-soft tissue ratios increased between 4 and 24 h but the latter increased more. In conclusion, only minor differences were

    Metastatic prostate cancer continues to be a leading cause of morbidity and mortality in men with prostate cancer. Over the last decade, the treatment landscape for patients with castrate-resistant disease has drastically changed, with several novel agents demonstrating an improvement in overall survival in large, multi-institutional randomized trials. Traditional treatment with radioisotopes has largely been in the palliative setting. However, the first in class radiopharmaceutical radium-223 has emerged as the only bone-directed treatment option demonstrating an improvement in overall survival. Medline publications from 1990 to 2016 were searched and reviewed to assess the use of currently approved radioisotopes in the management of prostate cancer including emerging data regarding integration with novel systemic therapies. New positron emission tomography-based radiotracers for advanced molecular imaging of prostate cancer were also queried. Radioisotopes play a crucial role in the diagnosis and treatment of prostate cancer in the definitive and metastatic setting. Molecular imaging of prostate cancer and theranostics are currently being investigated in the clinical arena. The use of modern radioisotopes in selected patients with mCRPC is associated with improvements in overall survival, pain control, and quality of life.

    Full Text Available Metastatic tumors are of great significance since few cases may represent the only symptom of an undiscovered underlying malignancy. Metastatic tumors rarely metastasize to the oral region despite the fact that many common primary neoplasms frequently metastasize to bone. The true incidence of metastatic tumors in the bones of the jaw is unknown, as jaws are not always included in radiographic skeletal surveys for metastasis. Sometimes oral metastasis may be the first evidence of metastasis from its primary site. A case of metastatic follicular thyroid carcinoma to the mandible is presented here, along with the discussion of clinical and histological features. The present case not only emphasizes the importance of considering metastasis in the differential diagnosis of a radiolucent lesion in the mandible, but also emphasizes in the improvement of the overall survival rate and treatment results by an early detection of metastatic disease.

  13. Preventing painful age-related bone fractures: Anti-sclerostin therapy builds cortical bone and increases the proliferation of osteogenic cells in the periosteum of the geriatric mouse femur.

    Age-related bone fractures are usually painful and have highly negative effects on a geriatric patient's functional status, quality of life, and survival. Currently, there are few analgesic therapies that fully control bone fracture pain in the elderly without significant unwanted side effects. However, another way of controlling age-related fracture pain would be to preemptively administer an osteo-anabolic agent to geriatric patients with high risk of fracture, so as to build new cortical bone and prevent the fracture from occurring. A major question, however, is whether an osteo-anabolic agent can stimulate the proliferation of osteogenic cells and build significant amounts of new cortical bone in light of the decreased number and responsiveness of osteogenic cells in aging bone. To explore this question, geriatric and young mice, 20 and 4 months old, respectively, received either vehicle or a monoclonal antibody that sequesters sclerostin (anti-sclerostin) for 28 days. From days 21 to 28, animals also received sustained administration of the thymidine analog, bromodeoxyuridine (BrdU), which labels the DNA of dividing cells. Animals were then euthanized at day 28 and the femurs were examined for cortical bone formation, bone mineral density, and newly borne BrdU+ cells in the periosteum which is a tissue that is pivotally involved in the formation of new cortical bone. In both the geriatric and young mice, anti-sclerostin induced a significant increase in the thickness of the cortical bone, bone mineral density, and the proliferation of newly borne BrdU+ cells in the periosteum. These results suggest that even in geriatric animals, anti-sclerostin therapy can build new cortical bone and increase the proliferation of osteogenic cells and thus reduce the likelihood of painful age-related bone fractures. © The Author(s) 2016.

    This retrospective study evaluated the toxicity and efficacy of strontium-89 chloride (Metastron, Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of treatment in patients with moderate and extensive bone involvement. The predictive value of flare response with regard to analgesic response was also studied. High-grade leukothrombopenians were observed after only 5% of injections. An improvement in quality of life was obtained in 65% of cases, a decrease in pain in 78% (31% complete response) and a reduction of analgesics in 60%. Efficacy was significantly better for pain decrease (P=0.005) and reduction of analgesics (P=0.018), and response was significantly longer (P<0.0035) in patients with moderate than in patients with extensive bone involvement. The flare response observed in 23% of cases was not predictive of pain response (P=0.919) or reduction of analgesics (P=0.353). A second dose prolonged analgesia in three-quarters of cases without any apparent increase in toxicity. These results confirm the benefit of {sup 89}Sr chloride for the treatment of metastatic bone pain and suggest that internal radiotherapy should be started earlier. A bone scan could be proposed at the time of hormonal escape resulting in bone pain, and internal radiotherapy could be initiated when several metastatic foci exist, even if only one is painful. In this way, pain-free follow-up could be prolonged, and the transition to other therapeutic approaches, particularly opioids, delayed. (orig.)

    The aim of this trial was to establish the effectiveness of traditional bone setting (TBS) compared with conventional physical and exercise therapy (PhT) in treating chronic low back pain (cLBP). Randomised clinical trial. Working-aged cLBP patients (n=131, age range 29-51 years) were randomised into two treatment groups: TBS and PhT. Follow-up assessments took place 1, 6 and 12 months after treatment. TBS is a popular traditional manual mobilisation therapy for musculoskeletal disorders in Finland. Conventional PhT was used as the reference treatment. LBP intensity (Visual Analog Scale 0-100, VAS), the Oswestry Disability Index (ODI), the global assessment score (scale -1 to +10), a health-related quality of life (HRQoL) assessment and spine mobility measurements were used as measures. 118 patients (95.9%, 59 men and 59 women) completed the treatment program. Both treatments reduced the VAS and ODI levels after 1 month. Changes in VAS did not differ between the two treatment groups (mean -0.2, CI -11.3 to 10.9). The improvement in ODI (mean 2.4, CI -1.2 to 6.0, p=0.069, repeated measurements ANOVA) and quality of life scores (mean -0.03, CI -0.06 to 0, p=0.056) tended to be greater after TBS. Additionally, global assessment scores were better for TBS-treated patients (Mann-Whitney test, p=0.001). There were no differences between the spine mobility test results of the two groups. Changes in both VAS (mean -2.4, CI -15.5 to 10.6) and ODI (mean 1.0, CI -3.0 to 5.1) measures did not, however, differ between the groups at the 1-year follow-up stage. Most cLBP patients found the treatments to be beneficial. Although the long-term dynamics of pain and disability did not differ between the groups, the subjective benefits appeared to be more significant after TBS.

Results. 215 men participated, CPCs were detected in 62.7%, DTCs in 62.2%, and mM in 71.4% in nonmetastatic cancer; in metastatic cancer all had CPCs, DTCs, and mM detected. All CPCs and DTCs expressed MMP-2; in mM MMP-2 expression was positively associated with increasing Gleason score. MMP-2 expression in CPCs and DTCs showed concordance. In low grade tumors, mM and surrounding stromal cells were MMP-2 negative, with variable expression in high grade tumors; in metastatic disease, both mM and stromal cells were MMP-2 positive. Conclusions. CPCs and DTCs are different from mM, with inhibition of MMP-2 expression in mM of low grade tumors. With disease progression, MMP-2 expression increases in both mM and surrounding stromal cells, with implications for the use of bisphosphonates or MMP-2 inhibitors.

    Radiation therapy is a medical specialty that uses ionizing radiation sources, and can be applied to relieve the pain. The Numerical Dosimetry Group (GDN) of Recife-PE, Brazil presented in June 2012 the SISRAD (Health information system in radiotherapy), developed to organize information about data of patients with bone metastasis, aiming to evaluate patterns of pain after radiation treatment. They have since been carried out interviews with this type of patient and the answers have been added to a data file of the software. Were developed some graphical visualization tools as well as data sheets. The current version of SISRAD reads the data file and displays graphics and numerical results, with options to save them or print them. In this paper is presented a roadmap for the health care professional use with efficiency the SISRAD to form quantitative profiles of intensity of pain that their patients, on their responsibility, feel after the radiation treatment. A hypothesis used in SISRAD consists of organizing the responses of the patients supposing them free from other effects other than those arising from the permanence of the pain he felt before treatment or modification by the treatment. So the way the information is handled in the SISRAD enable the trader can discern patterns of pain and, consequently, improve the quality of treatment. In this sense the computational tool here presented can be classified as educational software for health professionals

    Bone-seeking radiopharmaceuticals have palliative benefit in castration-resistant prostate cancer (CRPC) metastatic to bone. Recent studies have shown improvement of survival and quality of life when radiopharmaceuticals were given repeatedly or in combination with chemotherapy. We designed a phase I study combining docetaxel and {sup 186}Re-labelled hydroxyethylidene diphosphonate (HEDP) in men with CRPC and bone metastases to evaluate toxicity. A dose escalation schedule was designed consisting of four dose levels with a standard dosage of docetaxel (75 mg/m{sup 2} 3-weekly). {sup 186}Re-HEDP was given in increasing activities (1,250 MBq up to 2,500 MBq) after the third and sixth cycle of docetaxel. Dose limiting toxicity (DLT) was defined as any grade 4 toxicity lasting more than 7 days or any grade 3 toxicity that did not recover within 10 days. Three patients were planned for each dose level expanding to six if a DLT occurred. Fourteen patients were recruited with a median age of 64.6 years. One DLT, grade 3 thrombocytopenia lasting >10 days, occurred at dose level 3 leading to expansion of this group to six. One of these patients had an episode of acute renal failure which resolved. Because of production problems of {sup 186}Re-HEDP dose level 4 was not started. Combined therapy with docetaxel and {sup 186}Re-HEDP is generally well tolerated in patients with CRPC metastatic to bone. We will conduct a randomized phase II study using three cycles of docetaxel 75 mg/m{sup 2} 3-weekly followed by {sup 188}Re-HEDP 40 MBq/kg body weight, followed by another three cycles of docetaxel 75 mg/m{sup 2}, followed by {sup 188}Re-HEDP 20 MBq/kg body weight.

    To determine the association between bone marrow lesions (BMLs) and (teno)synovitis as assessed on magnetic resonance (MR) imaging in patients with pain in hand osteoarthritis (OA). In 105 consecutive primary hand OA patients (83% women, mean age 59 years), who were diagnosed by rheumatologists and included in the HOSTAS (Hand OSTeoArthritis in Secondary care) cohort, contrast enhanced MR imaging of right distal and proximal interphalangeal joints were obtained. In 92 patients joint site specific pain upon palpation was assessed within 3 weeks of magnetic resonance imaging (MRI) examination. MR features were scored (0-3) following the Oslo hand OA score: BMLs, synovitis, cysts, flexor tenosynovitis (FTS). Additionally, extensor tendon inflammation (ETI) (0-3) was scored. Odds ratios (OR, 95% confidence interval (CI)) were calculated using generalized estimating equations for MR features with joint pain, adjusted for putative confounders. Stratified analyses were performed to investigate interaction. BMLs, synovitis, cysts, FTS and ETI were demonstrated in 56%, 90%, 22%, 16% and 30% of patients, respectively. BMLs (grade 2/3 vs 0: 3.5 (1.6-7.7)) and synovitis (3 vs 0: OR 3.6 (95% CI 1.9-6.6)) were severity-dependent associated with joint pain, but FTS and ETI were not. Stratified analyses showed that BMLs did not associate with pain in the absence of synovitis, whereas synovitis was associated with pain in the absence of BMLs. Interaction was seen between BMLs and synovitis grade 2 or 3. In hand OA patients severe synovitis is associated with joint pain, which is worsened when BMLs co-occur, suggesting synovitis as primary target of treatment.

    Full Text Available Purpose: To report a case of orbital metastasis from scapular bone osteosarcoma. Case Report: A 55-year-old man who was a known case of scapular bone osteosarcoma, was referred to our clinic with ocular symptoms including acute painful decreased vision, proptosis, conjunctival injection, and chemosis. He had undergone surgical excision of the original tumor and received systemic chemotherapy 4 months before. Imaging studies and incisional biopsy were performed for the orbital lesion, the histopathological examination confirmed the diagnosis of metastatic osteosarcoma. The patient was referred to the oncologist for palliative chemotherapy and further intervention; however, he deceased 2 months later due to sepsis in the context of immunosuppression. Conclusion: Metastatic involvement of the orbit due to osteosarcoma is a rare condition manifesting with orbital mass, pain, diplopia and ocular motility disturbance. Although there is no effective treatment, the combination of modalities such as chemotherapy, radiotherapy, and surgery may delay progression of the disease.

    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

    Targeted radiopharmaceuticals have been mostly developed to visualize and/or treat oncologic diseases. In targeted radiotherapy radionuclide selection is a key issue, because the radionuclide should provide the appropriate radiation absorbed dose, matching the desirable biologic effect, but at the same time it should preclude irradiation of surrounding healthy tissues. Among the last generation of bisphosphonates with cyclic side chains, zoledronic acid is the most potent bisphosphonate, described till now, which inhibits bone resorption. In this paper, we describe the synthesis, properties and hydroxyapatite binding of zoledronic acid labeled with two low energy beta emitters, {sup 47}Sc and {sup 177}Lu. Radiochemicals labeled with low energy electron emitters are preferred, because they deliver both a therapeutic dose to the bone and spare the bone marrow. Hydroxyapatite adsorption experiments have shown that the binding values obtained with complexes of zoledronic acid labeled with {sup 46}Sc and {sup 177}Lu are much higher than those of bisphosphonates labeled with {sup 153}Sm and {sup 166}Ho. Hence, complexes of zoledronic acid with either {sup 46}Sc or {sup 177}Lu seems to be a promising radiopharmaceutical for bone pain therapy.

    Full Text Available Abstract Background This practice guideline was developed to provide recommendations to clinicians in Ontario on the preferred standard radiotherapy fractionation schedule for the treatment of painful bone metastases. Methods A systematic review and meta-analysis was performed and published elsewhere. The Supportive Care Guidelines Group, a multidisciplinary guideline development panel, formulated clinical recommendations based on their interpretation of the evidence. In addition to evidence from clinical trials, the panel also considered patient convenience and ease of administration of palliative radiotherapy. External review of the draft report by Ontario practitioners was obtained through a mailed survey, and final approval was obtained from the Practice Guidelines Coordinating Committee. Results Meta-analysis did not detect a significant difference in complete or overall pain relief between single treatment and multifraction palliative radiotherapy for bone metastases. Fifty-nine Ontario practitioners responded to the mailed survey (return rate 62%. Forty-two percent also returned written comments. Eighty-three percent of respondents agreed with the interpretation of the evidence and 75% agreed that the report should be approved as a practice guideline. Minor revisions were made based on feedback from the external reviewers and the Practice Guidelines Coordinating Committee. The Practice Guidelines Coordinating Committee approved the final practice guideline report. Conclusion For adult patients with single or multiple radiographically confirmed bone metastases of any histology corresponding to painful areas in previously non-irradiated areas without pathologic fractures or spinal cord/cauda equine compression, we conclude that: • Where the treatment objective is pain relief, a single 8 Gy treatment, prescribed to the appropriate target volume, is recommended as the standard dose-fractionation schedule for the treatment of symptomatic and

    The purpose of this study was to assess the incremental value of technetium-99m-methyl diphosphonate (Tc-MDP) single-photon emission computed tomography/computed tomography (SPECT/CT) over Tc-MDP two-phase bone scan (TPBS) in the assessment of the patients with pain following knee arthroplasty. Tc-MDP TPBS and Tc-MDP SPECT/CT were performed in 49 patients with knee pain after knee arthroplasty. The scans were reviewed by two readers (nuclear medicine physician and musculoskeletal radiologist). Tc-MDP SPECT/CT studies were interpreted in conjunction with TPBS in this retrospective study to identify the pain generator in painful knee prosthesis. The final diagnosis was established based on a combination of histopathological/cytological findings, other imaging findings (e.g. MRI, radiolabelled white scan), clinical decisions, and management outcomes (including subsequent intraoperative findings). In diagnosing infection or aseptic loosening, a definitive outcome regarding the presence/absence of aseptic loosening or periprosthetic infection was obtained in 41 patients. (a) Sensitivity of Tc-MDP SPECT/CT [100%; 95% confidence interval (CI): 66.4-100%] was higher than Tc-MDP TPBS (88.9%; 95% CI: 51.8-99.7%). (b) Specificity of Tc-MDP SPECT/CT (75%; 95% CI: 53.3-90.2%) was considerably higher than Tc-MDP TPBS (30%; 95% CI: 11.9-54.3%). Alternative diagnoses were identified in 21/49 (43%) patients on Tc-MDP SPECT/CT, which could not be ascertained on Tc-MDP TPBS alone. Tc-MDP SPECT/CT has better sensitivity and specificity compared with Tc-MDP TPBS in diagnosis of aseptic loosening and periprosthestic infection in patients with painful knee arthroplasty. Tc-MDP SPECT/CT identified alternative causes of pain in 43% of patients, which was not identified by Tc-MDP TPBS.

    Samarium-153 emits medium-energy beta particles an a gamma photon with a physical half-life of 46,3 hours. When chelated to ethylenediaminetetramethylenephosphonic acid (EDTMP), it is remarkably stable in vitro and in vivo. In this study we administered randomly 0,5 and 1,0 mCi/Kg body weight (two groups), to 30 patients with painful metastatic bone cancer. Slight and spontaneously reversible myelotoxicity was observed. A bigger leukocyte and platelet suppression was obtained with 1,0 mCi/kg than 0,5 mCi/Kg dose. Pain palliation was obtained in 66% of the treated patients. Our preliminary results indicate that 153 Sm-EDTMP is a promising radiotherapeutic agent for palliative treatment of metastatic bone cancer pain where a reactor is available and at a very affordable cost.

    Percutaneous radiotherapy is the most effective modality for treatment of metastatic bone cancer. Local irradiation improves overall quality of life by relieving pain in most patients. It also helps preventing complications as pathological fractures in lytic bone lesions by new bone formation. In a retrospective study on 100 patients, irradiated for lytic bone metastases, the radiotherapeutic effect on alleviation of pain and on recalcification rate was investigated. In our experience in 84% of the cases pain and disability associated with bone metastases could be decreased. 38% of the patients had complete relief of symptoms. A correlation between subjective therapy effect and histology of the primary tumor was not demonstrated. Remineralization was found in 67% of all irradiated skeletal areas (n=137) (recalcification rate in breast cancer 77%, in bronchial carcinoma 27%, and in renal cell carcinoma 25%). After a total dose of 30 Gy reduction of the metastases-associated pain was achieved in 81% of the cases and remineralization was observed in 70% of the cases. (orig.) [de

    The authors report a case of gastric, renal, pulmonary, and myocardial uptake of M.D.P.-Tc 99 m in a patient with parathyroid carcinoma. Parathyroid carcinoma is a rare cause of primary hyperparathyroidism which becomes complicated during its evolution by metastatic calcifications. Metastatic calcifications are frequently located in lungs and heart. If an adequate treatment is not undertaken, these calcifications progress and evolve into severe respiratory and cardiac complications. In our patient, quasi-complete disappearance of metastatic calcifications on the follow-up bone scintigraphy, performed four weeks after surgical cure of parathyroid tumour, indicates the great interest of this examination in early identification of metastatic calcifications and monitoring of their disappearance after treatment.

    Skeletal-related events (SREs) including pathologic fracture, spinal cord compression, radiation to bone and surgery to bone, are common in men with bone metastatic castration-resistant prostate cancer (mCRPC). Men with mCRPC are at high risk of death. Whether SREs predict mortality is unclear. We tested the association between SREs and overall survival (OS) in a multiethnic cohort with bone mCRPC, controlling for key covariates unavailable in claims data such as bone pain, number of bone metastases and PSA doubling time (PSADT). We collected data on 233 men diagnosed with nonmetastatic castration-resistant prostate cancer (CRPC) in 2000-2013 at two Veterans Affairs hospitals who later progressed to bone metastases. First occurrence of SRE and OS were collected from the medical records. Cox models were used to test the association between SRE and OS, treating SRE as a time-dependent variable. We adjusted for age, year, race, treatment center, biopsy Gleason, primary treatment to the prostate, PSA, PSADT, months from androgen deprivation therapy to CRPC, months from CRPC to metastasis and number of bone metastases at initial bone metastasis diagnosis. In a secondary analysis, we also adjusted for bone pain. During follow-up, 88 (38%) patients had an SRE and 198 (85%) died. After adjusting for risk factors, SRE was associated with increased mortality (hazard ratio (HR)=1.67; 95% confidence interval (CI) 1.22-2.30; P=0.001). When bone pain was added to the model, the association of SREs and OS was attenuated, but remained significant (HR=1.42; 95% CI 1.01-1.99; P=0.042). SREs are associated with increased mortality in men with bone mCRPC. Further studies on the impact of preventing SREs to increase survival are warranted.

    Full Text Available Multiple myeloma (MM cells interact with bone marrow stromal cells stimulating transcription and secretion of cytokines like IL-6 and IL-10, which are implicated in the progression and dissemination of MM. Regulation of cytokines secretion is under genetic control through genetic polymorphisms in their coding and promoter sequences. It seems that single nucleotide polymorphism (SNP in the promoter region of various genes may regulate the plasma concentrations of cytokines. Cytokines could be also hypothesized to function as pain modulators as peripheral nociceptors are sensitized by cytokines. The aim was to determine if the SNP of IL-6 and IL-10 cytokines could influence the analgesic response of radiotherapy in the treatment of painful bone destructions in MM patients. 30 patients (19 women and 11 men, median age: 67 years with MM and painful bone destructions were treated with palliative radiotherapy. Pain was evaluated according to the visual analogue scale and analgesics intake. Pain scores and analgesics use were measured prior to radiotherapy as well as 4, 12 and 24 weeks afterward. Opioid analgesics were converted to the morphine-equivalent daily dose (MEDD. Genomic DNA was extracted from peripheral blood leukocytes and IL-6 and IL-10 gene promoter polymorphisms were analysed with polymerase chain reaction. 60% of patients reported severe pain prior to radiotherapy, which decreased to 13% at the first follow-up visit (p <0.001. The MEDD on admission to the hospital was 75 mg/day which decreased to 46 mg/day at the first follow-up visit (p = 0.033. A significant parameter in pain relief was: age < 65 years (p=0.029. We analysed 6 SNPs in the gene promoter region of IL-6 (-597 G/A, -572 G/C, -174 G/C and IL-10 (-592 A/C, -819 C/T, -1082 A/G as well as their relation with pain severity and analgesic consumption.

    Full Text Available Objective: Optimized production and quality control of ytterbium-175 (Yb-175 labeled pamidronate and alendronate complexes as efficient agents for bone pain palliation has been presented. Methods: Yb-175 labeled pamidronate and alendronate (175Yb-PMD and 175Yb-ALN complexes were prepared successfully at optimized conditions with acceptable radiochemical purity, stability and significant hydroxyapatite absorption. The biodistribution of complexes were evaluated up to 48 h, which demonstrated significant bone uptake ratios for 175Yb-PAM at all-time intervals. It was also detected that 175Yb-PAM mostly washed out and excreted through the kidneys. Results: The performance of 175Yb-PAM in an animal model was better or comparable to other 175Yb-bone seeking complexes previously reported. Conclusion: Based on calculations, the total body dose for 175Yb-ALN is 40% higher as compared to 175Yb-PAM (especially kidneys indicating that 175Yb-PAM is probably a safer agent than 175Yb-ALN.

    Full Text Available PURPOSE: The aim of this study was to evaluate the degree of metastatic bone pain palliation and medullar toxicity associated with samarium-153-EDTMP treatment. METHODS: Seventy-three patients with metastatic bone pain having previously undergone therapy with samarium-153-EDTMP (1 mCi/kg were retrospectively evaluated. Routine follow-up included pain evaluation and blood counts for 2 months after treatment. Pain was evaluated using a subjective scale (from 0 to 10 before and for 8 weeks after the treatment. Blood counts were obtained before treatment and once a week for 2 months during follow-up. Dosimetry, based upon the urinary excretion of the isotope, was estimated in 41 individuals, and the resulting radiation absorbed doses were correlated with hematological data. RESULTS: Reduction in pain scores of 75% to 100% was obtained in 36 patients (49%, with a decrease of 50% to 75%, 25% to 50%, and 0% to 25% in, respectively, 20 (27%, 10 (14%, and 7 (10% patients. There was no significant relationship between the pain response and location of the primary tumor (breast or prostate cancer. Mild to moderate myelosuppression was noted in 75.3% of patients, usually with hematological recovery at 8 weeks. The mean bone marrow dose was 347 ± 65 cGy, and only a weak correlation was found between absorbed dose and myelosuppression (Pearson coefficient = .4. CONCLUSIONS: Samarium-153-EDTMP is a valuable method for metastatic bone pain palliation. A mild to moderate and transitory myelosuppression is the main toxicity observed after samarium therapy, showing a weak correlation with dosimetric measures.OBJETIVO: O presente trabalho teve por objetivo avaliar o efeito paliativo da dor e a toxicidade medular associados ao tratamento com Samário-153-EDTMP em pacientes com metástases ósseas.

    Objective: One of the common complaints in advanced breast cancer is pain. This is due to osseous metastasis. Analgesics, along with chemotherapy and hormonal therapy, are the mainstay of treatment. Multifocal bone disease that is refractory to above routine treatments can benefit from a series of agents like Pamidronate. Design: Prospective comparative study. Place and Duration of Study: Study was carried out from February 1998 to January 2001 in the Department of Radiotherapy / Oncology, Services Hospital, Lahore. Subjects and Methods: Sixty patients suffering from metastatic breast cancer (mainly to bones) initially treated with chemotherapy or hormonal therapy and analgesics were treated with 60-90 mg of injection Pamidronate by 4-hour intravenous infusion once a month for three or more months. The intensity of pain was assessed by the memorial symptom assessment scale and marked on the pain control performa according to frequency of pain, severity of pain or interference in daily activities due to pain at the start and after six months time of inclusion in the study. Difference in frequency of pain, severity or interference in daily routine was measured for each patient individually. Results: Marked pain relief was reported by 60% of patients who were additionally taking Pamidronate as compared to 43.3% patients who were not taking Pamidronate. Reduction in pain and analgesic demand is noted more in chemotherapy group with Pamidronate as compared to hormonal therapy group. Conclusion: Pamidronate can be additionally used in resistant cases for pain control. (author)

    Samarium-153 (Sm-153)-EDTMP is routinely used for pain palliation in skeletal metastasis, however most patients report partial response. Many strategies have been contemplated to make radiation therapy for pain more effective, one of them being the use of radiosensitizers. Capecitabine is a chemotherapeutic drug and is routinely combined with external beam radiation to make the target more radio-sensitive. Aim of the study was to evaluate whether combining capecitabine in radiosensitizing dose with Sm-153-EDTMP produces superior analgesia compared to Sm alone. Forty-four patients with skeletal metastases from various primaries were randomized into two groups: The study group received 1 mCi/kg Sm-153-EDTMP plus capecitabine (1,650 mg/m 2 ) orally for 8 days (equivalent to four t ½ of 153 Sm-EDTMP) and the control arm received 1 mCi/kg Sm-153-EDTMP plus placebo for the 8 days. After treatment, the patients were followed up for 12 weeks to evaluate the degree and duration of pain palliation and hematologic toxicity. All 44 patients reported different degrees of pain relief with none reporting complete pain relief for the entire duration of 12 weeks posttherapy observation period. However the level of pain relief obtained in study arm was significantly better than the control arm with mean posttherapy pain score being 1.29 ± 1.05 and 3.59 ± 2.77 respectively with P of 0.001. Transient and mild hematologic toxicity, as determined by World Health Organization criteria, was apparent in both arms without significant differences. The addition of a low-dose of capecitabine significantly enhances the analgesic effect of Sm-153 without any additional side effects

    Full Text Available This study is to investigate the role of Mas-related gene (Mrg C in the pathogenesis and treatment of bone cancer pain (BCP.BCP mouse model was established by osteosarcoma cell inoculation. Pain-related behaviors were assessed with the spontaneous lifting behavior test and mechanical allodynia test. Expression levels of MrgC, Gi, and NR2B in the spinal cord were detected with Western blot analysis and immunohistochemistry.Pain-related behavior tests showed significantly increased spontaneous flinches (NSF and decreased paw withdrawal mechanical threshold (PWMT in mouse models of BCP. Western blot analysis showed that, compared with the control group and before modeling, all the expression levels of MrgC, Gi, and NR2B in the spinal cord of BCP mice were dramatically elevated, which were especially increased at day 7 after operation and thereafter, in a time-dependent manner. Moreover, the treatment of MrgC agonist BAM8-22 significantly up-regulated Gi and down-regulated NR2B expression levels, in the spinal cord of BCP mice, in a time-dependent manner. On the other hand, anti-MrgC significantly down-regulated Gi expression, while dramatically up-regulated NR2B expression, in the BCP mice. Similar results were obtained from the immunohistochemical detection. Importantly, BAM8-22 significantly attenuated the nociceptive behaviors in the BCP mice.Our results indicated the MrgC-mediated Gi and NR2B expression alterations in the BCP mice, which might contribute to the pain hypersensitivity. These findings may provide a novel strategy for the treatment of BCP in clinic.

    Introduction: Radionuclide therapy (RNT) is an effective method for bone pain palliation in patients suffering from bone metastasis. Due to the long half-life, easy production and relatively low β- energy, 177 Lu [T 1/2 =6.73 days, E βmax =497 keV, E γ =113 keV (6.4%), 208 keV (11%)]-based radiopharmaceuticals offer logistical advantage for wider use. This paper reports the results of a multispecies biodistribution and toxicity studies of 177 Lu-EDTMP to collect preclinical data for starting human clinical trials. Methods: 177 Lu-EDTMP with radiochemical purity greater than 99% was formulated by using a lyophilized kit of EDTMP (35 mg of EDTMP, 5.72 g of CaO and 14.1 mg of NaOH). Biodistribution studies were conducted in mice and rabbits. Small animal imaging was performed using NanoSPECT/CT (Mediso, Ltd., Hungary) and digital autoradiography. Gamma camera imaging was done in rabbits and dogs. Four levels of activity (9.25 through 37 MBq/kg body weight) of 177 Lu-EDTMP were injected in four groups of three dogs each to study the toxicological effects. Results: 177 Lu-EDTMP accumulated almost exclusively in the skeletal system (peak ca. 41% of the injected activity in bone with terminal elimination half-life of 2130 and 1870 h in mice and rabbits, respectively) with a peak uptake during 1-3 h. Excretion of the radiopharmaceutical was through the urinary system. Imaging studies showed that all species (mouse, rat, rabbit and dog) take up the compound in regions of remodeling bone, while kidney retention is not visible after 1 day postinjection (pi). In dogs, the highest applied activity (37 MBq/kg body weight) led to a moderate decrease in platelet concentration (mean, 160 g/L) at 1 week pi with no toxicity. Conclusion: The protracted effective half-life of 177 Lu-EDTMP in bone supports that modifying the EDTMP molecule by introducing 177 Lu does not alter its biological behaviour as a specific bone-seeking tracer.

    The results of radiation therapy for metastatic spinal tumors were evaluated in terms of pain relief, improvement of neurological impairment, and survival. Between 1986 and 1995, 52 symptomatic patients with metastatic spinal tumors treated with radiation therapy were evaluated. The patients all received irradiation of megavoltage energy. Therapeutic efficacy was evaluated in terms of pain relief and improvement of neurological impairment. Pain relief was observed in 29 (61.7%) of 47 patients with pain. Therapy was effective for 17 (70.8%) of 24 patients without neurological impairment, and efficacy was detected in 12 (52.2%) of 23 patients with neurological impairment. Improvement of neurological symptoms was obtained in seven (25.0%) of 28 patients with neurological impairment. Radiation therapy was effective for pain relief in patients with metastatic spinal tumors. In patients with neurological impairment, less pain relief was observed than in those without impairment. Improvement of neurological impairment was restricted, but radiation therapy was thought to be effective in some cases in the early stage of neurological deterioration. Radiation therapy for metastatic spinal tumors contraindicated for surgery was considered effective for improvement of patients' activities of daily living. (author)

    Purpose: In order to better define variables and factors that may influence the pain response to radiation, and to look for a radiation regimen that can assure the highest percentage and the longest duration of pain relief, we performed a prospective, although not randomized, study on patients with bone metastases from various primary sites. Methods and Materials: From December 1988 to March 1994, 205 patients with a total of 255 solitary or multiple bone metastases from several primary tumors were treated in our radiotherapy center with palliative intent. Irradiation fields were treated with three main fractionation schedules: (1) Conventional fractionation: 40-46 Gy/20-23 fractions in 5-5.5 weeks; (2) Short course: 30-36 Gy/10-12 fractions in 2-2.3 weeks; (3) Fast course: 8-28 Gy/1-4 consecutive fractions. Pain intensity was self-assessed by patients using a visual analogic scale graduated from 0 (no pain) to 10 (the strongest pain one can experience). Analgesic requirement was assessed by using a five-point scale, scoring both analgesic strength and frequency (0 = no drug or occasional nonopioids; 1 = Nonopioids once daily; 2 = Nonopioids more than once daily; 3 = Mild opioids (oral codeine, pentazocine, etc.), once daily; 4 = Mild opioids more than once daily; 5 = Strong opioids (morphine, meperidine, etc.). Complete pain relief meant the achievement of a score ≤ 2 in the pain scale or 0 in the analgesic requirement scale. Partial pain relief indicated a score of 3 to 4 or of 1 to 2 on the former and latter scale, respectively. Results: Total pain relief (complete + partial) was observed in 195 (76%) sites, in 158 of which (62%) a complete response was obtained. Metastases from NSC lung tumors appeared to be the least responsive among all primary tumors, with 46% complete pain relief in comparison to 65% and 83% complete relief in breast (p = 0.04) and in prostate metastases (p 0.002), respectively. A significant difference in pain relief was detected among

    We report a case of a 39-year-old man with intractable multifocal pain caused by metastatic urachal carcinoma to the bone. The patient underwent a partial cystectomy in May 2008, and lung metastasis occurred 9 months after the surgery. He then received salvage chemotherapy, but developed metastasis to the liver, brain, and bone. He was hospitalized due to a shoulder pain, a lower back pain, buttocks pain, numbness in both legs, and drop foot in right leg. MRI revealed metastases to the spine, and lumbar spinal canal stenosis with cauda equina compression. Even a combination of fentanyl-patch, oral acetaminophen, gabapentin and paroxetine was not effective for pain control. Strontium-89 therapy and subarachnoid phenol block successfully eliminated intractable pain. The patient could be discharged from hospital and received a palliative care at home for a short period of time. (author)

    Objectives: To evaluate the effectiveness of samarium-153 (153Sm) lexidronam (EDTMP) in treatment of bone metastases. Methods: 380 patients with bone metastases were studied (221 men, 159 women; average age 65.3 y; ranged 27-91 y; average weight 59.3 kg, ranged 39-95 kg). The tumor types were prostate carcinoma (n=155), pulmonary carcinoma (n=92), breast cancer (n=57), gastric carcinoma (n=12), colorectal carcinoma (n=22), nasopharyngeal carcinoma (n=8), lymphoma (n=8), hepatic carcinoma (n=6), ovary carcinoma (n=4) and others (n=16). All patients were received 135Sm-EDTMP 0.8 or 1.0 mCi/kg during 1 to 7 course of treatment. Patients and physician evaluations were used to assess pain relief. Numbers of metastatic foci and activity of ROIs were used to observe post-therapy change in bone scanning. Results: In 380 patients, pain relief was observed in 257 patients (67.6%). Persistence of pain relief was seen through 2 to 24 weeks. The mean relief time is 5.8±3.4 weeks. KPS score was higher 10% than pre-therapy (71.2%±9.6% Vs 80.9%±10.3%, p<0.001). Numbers of metastatic foci (11.2+8.8 Vs 8.4±5.7, p<0.001) and activity of ROIs (3.28±2.04 Vs 2.15±0.94, p<0.01) were less than pre-therapy. Bone marrow suppression was mild and reversible (5.87±1.56 Vs 4.94±1.16 x 109/L). Conclusions: 153Sm-EDTMP provided relief of pain associated with bone metastases and inhibition of metastatic foci. As a relief drug of painful bone metastases, 153Sm-EDTMP is safe and effective. (authors)

    Conventional radiologic modalities provide details only about the anatomic aspect of the various structures of the spine. Frequently the structures that show abnormal morphology may not be the cause of low back pain (LBP). Functional imaging in the form of bone scan along with single photon emission computerized tomography (SPECT/CT) may be helpful in identifying structures causing pain, whether morphologically normal or not. The objective of this study is to evaluate the role of bone scan with SPECT/CT in management of patients with LBP. This is randomized double-blinded controlled study performed on 80 patients with LBP aged 20 to 80 years, ASA physical status I to III. Patients were randomized into bone scan and control groups consisting of 40 patients each. On the basis of the clinical features and radiologic findings a clinical diagnosis was made. After making a clinical diagnosis, the patients in bone scan group were subjected to bone scan with SPECT/CT. On the basis of the finding of the bone scan and SPECT/CT, a new working diagnosis was made and intervention was performed according to the new working diagnosis. Diagnostic blocks in the control group were given based on clinical diagnosis. Controlled comparative diagnostic blocks were performed with local anesthetic. The pain score just after the diagnostic block and at the time of discharge (approximately 4 h later) was recorded; the pain relief was recorded in percentage. In both the groups, sacroilitis was the most common diagnosis followed by facet joint arthropathy. The number of patients obtaining pain relief of >50% was significantly higher in the bone scan-positive group as compared with the control group. Three new clinical conditions were identified in the bone scan group. These conditions were multiple myeloma, avascular necrosis of the femoral head, and ankylosing spondylitis. Bone scan with SPECT/CT was found to complement the clinical workup of patients with LBP. Inclusion of bone scan with

    Conclusion:. Even when the tumor is confined to a single load-bearing bone, CIBP drives a significant loss of activity, which increases with disease progression. Understanding the mechanisms that drive this reduction in activity may allow the development of therapies that allow CIBP patients to better maintain their activity and functional status.

    Conclusions: Different fractionation of radiation has same response and toxicity in treatment of vertebral bone metastasis. Single fraction RT may be safely used to treat these cases as this is more cost effective and less time consuming. Studies may be conducted to find out particular subgroup of patients to be benefitted more by either fractionation schedule; however, our study cannot comment on that issue.

    It was the aim of this study to evaluate different markers of inflammation such as 99m-Tc-labelled human immunoglobulin G and 99m-Tc-nanocolloid with respect to their ability to detect inflammatory or degenerative affections of small joints of hand and fingers. While conventional bone scanning reveals good agreement with clinical findings it is not well suited for screening of inflammatory processes due to its poor specificity. In small joints conventional three-phase bone scan with information of perfusion, blood pool and accumulation is not suitable due to the small ROI, low count rate with high statistics. Therefore we used inflammatory markers to overcome this problem. Immunoglobulin G was true positive in case of inflammatory lesions in 69%, and false positive in case of degenerative lesions in 24%, while nanocolloid was true positive in 72% and false positive in 14%, respectively. Significant differences were found between markers of inflammation and the bone scanning agent while both inflammatory markers, immunoglobulin G and nanocolloid demonstrated significant correlation. While bone scanning tracers detect all kinds of joint affections, immunoglobulin G and nanocolloid accumulate preferentially in inflammatory joints and therefore might be useful to differentiate between inflammatory and degenerative lesions.

    Full Text Available Osteosarcoma is the most common bone cancer in dogs and people. In order to improve clinical outcomes, it is necessary to identify proteins that are differentially expressed by metastatic cells. Membrane bound proteins are responsible for multiple pro-metastatic functions. Therefore characterizing the differential expression of membranous proteins between metastatic and non-metastatic clonal variants will allow the discovery of druggable targets and consequently improve treatment methodology. The objective of this investigation was to systemically identify the membrane-associated proteomics of metastatic and non-metastatic variants of human and canine origin. Two clonal variants of divergent in vivo metastatic potential from human and canine origins were used. The plasma membranes were isolated and peptide fingerprinting was used to identify differentially expressed proteins. Selected proteins were further validated using western blotting, flow cytometry, confocal microscopy and immunohistochemistry. Over 500 proteins were identified for each cell line with nearly 40% of the proteins differentially regulated. Conserved between both species, metastatic variants demonstrated significant differences in expression of membrane proteins that are responsible for pro-metastatic functions. Additionally, CD147, CD44 and vimentin were validated using various biochemical techniques. Taken together, through a comparative proteomic approach we have identified several differentially expressed cell membrane proteins that will help in the development of future therapeutics.

    Bone marrow aspiration and trephine (BMAT) biopsies remain important tests in haematology. However, the procedures can be moderately to severely painful despite standard methods of pain relief. To test the efficacy of transcutaneous electrical nerve stimulation (TENS) in alleviating the pain from BMAT in addition to standard analgesia using a numerical pain rating scale (NRS). 70 patients requiring BMAT were randomised (1:1) in a double-blind, placebo-controlled trial. -35 patients received TENS impulses at a strong but comfortable amplitude (intervention group) and 35 patients received TENS impulses just above the sensory threshold (control group) (median pulse amplitude 20 and 7 mA, respectively). Patients and operators were blinded to group allocation. Pain assessments were made using a numerical pain scale completed after the procedure. No significant difference in NRS pain recalled after the procedure was detected (median pain score 5.7 (95% CI 4.8 to 6.6) in control vs 5.6 (95% CI 4.8 to 6.4) in the intervention group). However, 100% of patients who had previous experience of BMAT and >94% of participants overall felt they benefited from using TENS and would recommend it to others for this procedure. There were no side effects from the TENS device, and it was well tolerated. TENS is a safe, non-invasive adjunct to analgesia for reducing pain during bone marrow biopsy and provides a subjective benefit to most users; however, no objective difference in pain scores was detected when using TENS in this randomised controlled study.

    To describe usual care received by women with bony metastatic breast cancer (ICD-9: 174.xx and 198.5) treated in a United States specialty cancer hospital, an Electronic Medical Record (EMR)-based retrospective review identified 111 deceased female breast cancer patients ≥18 years of age treated with zoledronic acid (ZOL). Baseline symptoms included bone pain/fracture (58.6%), breathing difficulties (24.3%), or mental status changes (11.7%). ZOL was started at/after metastatic diagnosis for 75.7% of women (N = 84), with average administration of 15.9 months (median 11.3). Nearly 20% required reduced ZOL doses, most (54.5%) due to impaired renal function; 61.3% discontinued ZOL due to patient death/disease progression. Adverse events were reported in 10.8%, while 0.9% (N = 1) had a documented osteonecrosis of the jaw. Initiation of palliative care should be considered early in patients with a history of metastatic breast cancer who report bone pain or other skeletal-related events. Copyright © 2012 Elsevier Ltd.

    Conclusion: This case highlights the possibility of a missed fish bone perforation causing chronic postprandial abdominal pain and discomfort in a patient with a Roux-en-Y gastric bypass anatomy. Foreign body perforation is a rare cause of abdominal pain after gastric bypass that should be considered when evaluating chronic abdominal pain symptoms after LRYGP.

    Cancer induced bone pain (CIBP) remains one of the most intractable clinical problems due to poor understanding of its underlying mechanisms. Recent studies demonstrate the decline of inhibitory interneurons, especially GABAergic interneurons in the spinal cord, can evoke generation of chronic pain. It has also been reported that neuronal MHC-I expression renders neurons vulnerable to cytotoxic CD8 + T cells and finally lead to neurons apoptosis in a variety neurological disorders. However, whether MHC-I could induce the apoptosis of GABAergic interneurons in spinal cord and contribute to the development of CIBP remains unknown. In this study, we investigated roles of MHC-I and underlying mechanisms in CIBP on a rat model. Our results showed that increased MHC-I expression on GABAergic interneurons could deplete GABAergic interneurons by inducing their apoptosis in the spinal dorsal horn of tumor-bearing rats. Pretreatment of MHC-I RNAi-lentivirus could prevent the apoptosis of GABAergic interneurons and therefore alleviated mechanical allodynia induced by tumor cells intratibial injection. Additionally, we also found that CD8 + T cells were colocalized with MHC-I and GABAergic neurons and presented a significant and persistent increase in the spinal cord of tumor-bearing rats. Taken together, these findings indicated that MHC-I could evoke CIBP by promoting apoptosis of GABAergic interneurons in the dorsal horn, and this apoptosis was closely related to local CD8 + T cells.

    The purpose of our study has been to evaluate the efficacy of single photon emission computed tomography (SPECT) over planar bone scan in identifying solitary vertebral lesions in patients with low backache and its ability to differentiate various pathologies according to the uptake pattern. Materials and Methods: The study included twenty patients out of whom six patients presented with known carcinoma and fourteen patients with low back pain. SPECT was done in all following planar skeletal survey. Benign and malignant lesions were identified according to the uptake pattern in vertebral elements, based on Gary F. Gates observations. Final diagnosis was obtained by means of biopsy or correlation with radiograph or computed tomography (CT) or magnetic resonance imaging (MRI), and/or follow up. Results: SPECT detected additional 30% of solitary vertebral lesions that were obscured on planar scan. Seven out of twenty were localized in anterior vertebral body and were diagnosed as benign ostophytes in six and osteoma in one substantiating the previous observations. Out of six cases of known carcinoma, three were having solitary metastases and showed posterior vertebral body uptake with pedicle involvement. SPECT could localize specific lesions as source of pain in eleven patients with low back pain (78%) and identified various etiologies including benign tumors (osteoid osteoma and osteoma), facet arthritis, discitis, transverse process fractures and spondylolysis. Conclusion: Our study highlighted the higher diagnostic value of SPECT over planar skeletal scintigraphy in localizing solitary vertebral lesions in low backache patients. Based on SPECT pattern, malignant and benign lesions could be differentiated in the given clinical context. (author)

    Full text: Radionuclide pain palliation therapy was done in 156 patients (1995-2007). Total 176 therapy were done. Mean age at the time of presentation was 56 yrs (13-81) with 114 patients were male. Most common referral diagnosis was Carcinoma prostate (86 patients) followed by Breast (38), lung (6) and other malignancies. Earlier oral Phosphorus-32 was used in a mean dose 3.15 mCi (2.5-4 mCi) in 20 patients, intravenous Phosphorus-32 6.7 mCi (4.5-7 mCi) in 138 pts and Samarium-153 52.8 mCi (45-95 mCi) in 14 patients. Most of the patients were referred at very advanced stage so follow up rate was low 25∼30% (40 patients only). Mean follow up duration was 3.75 months. Out of 40 patients significant pain relief was noted in 33 patients while no change was noted in 7 patients. Pre-treatment pain score and narcotic score were 7.6 and 4.5. Average hemoglobin, white blood cell and platelet count was 10.8, 7,800 and 2,05,000 respectively. After administration of radionuclide therapy there was a predictive fall in platelet count only. It decreased to 1,43,000 at around 4-5 weeks. Post-treatment pain score and narcotic score were 5 and 3.5 (P<0.005 as compared with pretreatment level). No serious toxicity was noted in any patient. Despite of most of the patient being in very advance stage of cancer significant relief was noted in 83% patients. Radionuclide therapy is a safe option even in advanced cancer with minimal toxicity

Phosphorus-32 was used in a mean dose 6.15 mCi (4.5-7 mCi) in 15 pts. and Samarium-153, 60 mCi (45-95 mCi) in 20 therapies. Strict follow up data was available in all patients. Mean follow up duration was 13.75 months (6 month - 20 months). Re-therapy was done after an interval of 4.7 months on an average. Pre-treatment pain score and narcotic score were 6.8 and 3.5. Average Hemoglobin, white blood cell and platelet count was 11.2, 8,600 and 1,89,000 respectively. After administration of radionuclide therapy there was a predictive but fully recovered fall in platelet counts only. It decreased to a mean 1,63,000 at around 4-5 weeks. Post-treatment pain score and narcotic score were 4.1 and 2.5 (P<0.005 as compared with pretreatment level). No serious toxicity was noted in any patient. Radionuclide pain palliation remains a very safe and effective option. Retherapy can be done very easily will equally good effects. No hematological toxicity was seen in any of the patient

    Determining the actual painful vertebral level is difficult when evaluating osteoporotic vertebral fracture, especially when there are acute and chronic fractures simultaneously. In this study, we retrospectively evaluated and compared the findings between plain film, bone scan, and magnetic resonance imaging (MRI) in the diagnosis of new fracture in osteoporotic vertebral fractures. This is a retrospective clinical study of patients who were diagnosed with osteoporotic vertebral fractures using plain film, bone scan, and MRI within a 1-month interval between February 2008 and December 2012. The findings in plain film, the extent of increased uptake in bone scan, and signal change in MRI were compared to evaluate the actual level of pain. All patients received percutaneous vertebroplasty according to MR finding. Pain scores (visual analog scale) of the study patients were compared prior to and after the procedure. A total of 52 patients with a mean age of 79.1 years (range 59-92 years) were enrolled in this study, and were treated by vertebroplasty confirmed by MRI. It was observed that patient pain score (visual analog scale) improved from 7.6 to 2.8. Plain film examination revealed 79 vertebrae that were suspected to be compression fractures. Among the suspected vertebrae, 62 showed increased uptake in bone scan, and MRI showed bony edema change in 58 vertebrae. The consistency between bone scan and MRI was 96.9% in patients with single-level suspected fracture on plain film. There was moderate agreement (kappa was 0.56) in patients where multiple levels were noted. Fifteen vertebrae with vacuum cleft sign on plain film showed total concordance in both bone scan and MRI. For patients with single-level compression fracture, the painful level in osteoporotic vertebral fractures can be determined by plain film and bone scan testing. Vacuum cleft sign noted on plain film may be enough to localize the level of pain. However, MRI testing is further needed in multiple

    Vimentin was originally identified as an intermediate filament protein present only as an intracellular component in many cell types. However, this protein has now been detected on the surface of a number of different cancer cell types in a punctate distribution pattern. Increased vimentin expression has been indicated as an important step in epithelial-mesenchymal transition (EMT) required for the metastasis of prostate cancer. Here, using two vimentin-specific monoclonal antibodies (SC5 and V9 directed against the coil one rod domain and the C-terminus of the vimentin protein, respectively), we examined whether either of these domains would be displayed on the surface of three commonly studied prostate cancer cell lines isolated from different sites of metastases. Confocal analysis of LNCaP, PC3 and DU145 prostate cancer cell lines (derived from lymph node, bone or brain prostate metastases, respectively) demonstrated that both domains of vimentin are present on the surface of these metastatic cancer cell types. In addition, flow cytometric analysis revealed that vimentin expression was readily detected along with CD44 expression but only a small subpopulation of prostate cancer cells expressed vimentin and the putative stem cell marker CD133 along with CD44. Finally, Cowpea mosaic virus (CPMV) nanoparticles that target vimentin could bind and internalize into tested prostate cancer cell lines. These results demonstrate that at least two domains of vimentin are present on the surface of metastatic prostate cancer cells and suggest that vimentin could provide a useful target for nanoparticle- or antibody- cancer therapeutic agents directed against highly invasive cancer and/or stem cells.

    Full text: Objective: This study describes the initial experience in the use of low-dose 1-131 MIBG in patients with metastaticl refractory Neuroblastoma given at 18.5 Mbql Kg (0.5 mCi/Kg )to (1) achieve disease palliation (i.e., pain I symptom control) and improvement in the quality of life, through subjective response from patient/carers and (2) allow day-admission to minimize hospital stay providing more quality time between the patients and carers. Methods: Patients with refractory and metastatic Neuroblastoma whose primary treatment goal at that particular stage is pain palliation were given low-dose 1-131 M IBG at a dose of 18.5 Mbql Kg ( 0.5 mCil Kg)l. Assessment of subjective pain relief following 1-131 MIBG was done through interviews from hospital visits of the patient and home visits by the team. Results: Four patients underwent Low-Dose 1-131 MIBG Therapy for pain palliation between May 2007- March 2008. Median age was 5.75 years old and median total dose given was 539 Mbql patient (14.5 mCil patient). All patients at a cenain time had relief from disease pain allowing them to communicate with family and participate in physical activities not priyiledged before. Observations gathered from carersl parents revealed that the overall quality-of-life improved after the 1-131 MIBG therapy with concurrent pain medication protocol. Conclusion: This initial I pilot study described achievement of disease palliation (i.e., pain and symptom control) and improvement in the quality of life of Stage IV Neuroblastoma patients and allows day-admissions providing more quality time between the patient and the family and reduces patient anxiety.

    Rapid and effective treatment of cancer-induced bone pain remains a clinical challenge and patients with bone metastasis are more likely to experience severe pain. The voltage-gated sodium channel Nav1.8 plays a critical role in many aspects of nociceptor function. Therefore, we characterized a rat model of cancer pain and investigated the potential role of Nav1.8. Adult female Wistar rats were used for the study. Cancer pain was induced by inoculation of Walker 256 breast carcinosarcoma cells into the tibia. After surgery, mechanical and thermal hyperalgesia and ambulation scores were evaluated to identify pain-related behavior. We used real-time RT-PCR to determine Nav1.8 mRNA expression in bilateral L4/L5 dorsal root ganglia (DRG) at 16-19 days after surgery. Western blotting and immunofluorescence were used to compare the expression and distribution of Nav1.8 in L4/L5 DRG between tumor-bearing and sham rats. Antisense oligodeoxynucleotides (ODNs) against Nav1.8 were administered intrathecally at 14-16 days after surgery to knock down Nav1.8 protein expression and changes in pain-related behavior were observed. Tumor-bearing rats exhibited mechanical hyperalgesia and ambulatory-evoked pain from day 7 after inoculation of Walker 256 cells. In the advanced stage of cancer pain (days 16-19 after surgery), normalized Nav1.8 mRNA levels assessed by real-time RT-PCR were significantly lower in ipsilateral L4/L5 DRG of tumor-bearing rats compared with the sham group. Western-blot showed that the total expression of Nav1.8 protein significantly decreased bilaterally in DRG of tumor-bearing rats. Furthermore, as revealed by immunofluorescence, only the expression of Nav1.8 protein in small neurons down regulated significantly in bilateral DRG of cancer pain rats. After administration of antisense ODNs against Nav1.8, Nav1.8 protein expression decreased significantly and tumor-bearing rats showed alleviated mechanical hyperalgesia and ambulatory-evoked pain.

    This retrospective study evaluated the efficacy and toxicity of {sup 89}strontium chloride (Metastron - Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of the treatment according to extension of bone involvement, moderate or extensive. The predictive value of Flare response for antalgic efficacy was also studied. Grade III/IV leuko-thrombopenia was observed after only 5% of injections. An improvement of the quality of life was obtained in 65% of cases, a decrease of pain in 78% (31% complete response) and reduction of antalgic intake in 60%. Efficacy was significantly better for pain decrease (p=0,005) and reduction of antalgic intake (p=0,018), and response duration was significantly longer (p<0,0035) in patients with moderate than extensive bone involvement. The Flare response observed in 23% of cases was not predictive of pain response (p=0,0919) and reduction of antalgic (p=0,353). A second dose prolonged antalgic in three-fourth of cases without any apparent increase of toxicity. These results confirm the benefit of {sup 89}strontium chloride for treatment of metastatic bone pain and suggest that internal radiotherapy should be started earlier. A bone scan could be proposed at the time of hormonal escape and bone pain, and internal radiotherapy could be initiated when several metastatic foci exist, even if only one is painful. Thus, pain-free follow up could be prolonged, and transition to other therapeutic approaches, particularly opioids, delayed. (author)

  12. Exuberant sprouting of sensory and sympathetic nerve fibers in nonhealed bone fractures and the generation and maintenance of chronic skeletal pain.

    Skeletal injury is a leading cause of chronic pain and long-term disability worldwide. While most acute skeletal pain can be effectively managed with nonsteroidal anti-inflammatory drugs and opiates, chronic skeletal pain is more difficult to control using these same therapy regimens. One possibility as to why chronic skeletal pain is more difficult to manage over time is that there may be nerve sprouting in nonhealed areas of the skeleton that normally receive little (mineralized bone) to no (articular cartilage) innervation. If such ectopic sprouting did occur, it could result in normally nonnoxious loading of the skeleton being perceived as noxious and/or the generation of a neuropathic pain state. To explore this possibility, a mouse model of skeletal pain was generated by inducing a closed fracture of the femur. Examined animals had comminuted fractures and did not fully heal even at 90+days post fracture. In all mice with nonhealed fractures, exuberant sensory and sympathetic nerve sprouting, an increase in the density of nerve fibers, and the formation of neuroma-like structures near the fracture site were observed. Additionally, all of these animals exhibited significant pain behaviors upon palpation of the nonhealed fracture site. In contrast, sprouting of sensory and sympathetic nerve fibers or significant palpation-induced pain behaviors was never observed in naïve animals. Understanding what drives this ectopic nerve sprouting and the role it plays in skeletal pain may allow a better understanding and treatment of this currently difficult-to-control pain state.

    Our aim was to quantify nociceptive spontaneous behaviors, knee edema, proinflammatory cytokines, bone density, and microarchitecture in high-fat diet (HFD)-fed mice with unilateral knee arthritis. ICR male mice were fed either standard diet (SD) or HFD starting at 3 weeks old. At 17 weeks, HFD and SD mice received intra-articular injections either with Complete Freund's Adjuvant (CFA) or saline into the right knee joint every 7 days for 4 weeks. Spontaneous pain-like behaviors and knee edema were assessed for 26 days. At day 26 post-first CFA injection, serum levels of IL-1β, IL-6, and RANKL were measured by ELISA, and microcomputed tomography analysis of knee joints was performed. HFD-fed mice injected with CFA showed greater spontaneous pain-like behaviors of the affected extremity as well as a decrease in the weight-bearing index compared to SD-fed mice injected with CFA. Knee edema was not significantly different between diets. HFD significantly exacerbated arthritis-induced bone loss at the distal femoral metaphysis but had no effect on femoral diaphyseal cortical bone. HFD did not modify serum levels of proinflammatory cytokines. HFD exacerbates pain-like behaviors and significantly increases the magnitude of periarticular trabecular bone loss in a murine model of unilateral arthritis. © 2016 The Obesity Society.

    Full Text Available Metastatic carcinomas from a distant primary malignancy involving the temporal bone particularly the jugular foramen are rare tumors. A 57-year-old gentleman had multiple gradually increasing swellings over the body since many years. For last two years, he noticed enlargement of the swelling in left calf and rapidly enlarging painful new swelling over the left chest wall in back for last one year. He had recent involvement of left seventh, eighth and lower cranial nerves. CT scan showed an extensive lesion in left jugular foramen region with bone destruction. The patient underwent decompression of the left jugular foramen mass lesion. The tumor was extremely vascular and a partial decompression could only be performed. Although there was relief in the headache but the neurological deficits were persisting. Histopathology of the tumor showed features of metastatic small ling cancer. In the present case, there was presence of long standing multiple swelling all over the body and the patient had painful enlargement that he perceived as an ongoing process of the von Recklinghausen′s disease and made a delay in seeking the medical advice resulting in a well advanced disease and with poor prognosis.

    To prospectively evaluate the predictive value of various bone formation and resorption markers in patients with bone metastases from prostate cancer after palliative treatment with 186 Re-1,1-hydroxyethylidene diphosphonate ( 186 Re-HEDP). Included in the study were 36 men with prostate cancer, suffering from painful osseous metastases and treated with 186 Re-HEDP. None had received any treatment that would have interfered with bone metabolism before 186 Re-HEDP treatment or throughout the follow-up period. For each patient, pretreatment and posttreatment serum levels of osteocalcin (OC), bone alkaline phosphatase (BALP), aminoterminal (PINP) and carboxyterminal (PICP) propeptides of type I collagen, amino-terminal (NTx) and carboxyterminal (CTx) telopeptides of type I collagen and their combinations were compared with the level and duration of pain response to radionuclide treatment. Pain response was correlated only with pretreatment ΝΤx/PINP, PICP/PINP and NTx/CTx ratios and posttreatment decrease in baseline NTx and PICP values (p=0.0025-0.035). According to multivariate and ROC analyses, the best marker-derived predictors of better and longer duration of response to 186 Re-HEDP treatment were a posttreatment decrease in NTx of ≥20% (RR=3.44, p=0.0005) and a pretreatment NTx/PINP ratio of ≥1.2 (RR=3.04, p=0.036) NTx, a potent collagenous marker of bone resorption, along with the novel NTx/PINP ratio provide useful cut-off values for identifying a group of patients suffering from painful osseous metastases from hormone-refractory prostatic carcinoma who do not respond to palliative treatment with 186 Re-HEDP. This information could help avoid an inefficient and expensive radionuclide treatment. Also, in the cohort of patients who will eventually undergo such treatment, the medium-term posttreatment changes in NTx offer valuable predictive information regarding long-term palliative response.

    Full Text Available Abstract Background Previous studies have demonstrates that, after nerve injury, extracellular signal-regulated protein kinase (ERK activation in the spinal cord-initially in neurons, then microglia, and finally astrocytes. In addition, phosphorylation of ERK (p-ERK contributes to nociceptive responses following inflammation and/or nerve injury. However, the role of spinal cells and the ERK/MAPK pathway in cancer-induced bone pain (CIBP remains poorly understood. The present study analyzed activation of spinal cells and the ERK/MAPK pathway in a rat model of bone cancer pain. Results A Sprague Dawley rat model of bone cancer pain was established and the model was evaluated by a series of tests. Moreover, fluorocitrate (reversible glial metabolic inhibitor and U0126 (a MEK inhibitor was administered intrathecally. Western blots and double immunofluorescence were used to detect the expression and location of phosphorylation of ERK (p-ERK. Our studies on pain behavior show that the time between day 6 and day 18 is a reasonable period ("time window" as the remaining stages to investigate bone cancer pain mechanisms and to research analgesic drugs. Double-labeling immunofluorescence revealed that p-ERK was sequentially expressed in neurons, microglia, and astrocytes in the L4-5 superficial spinal cord following inoculation of Walker 256 cells. Phosphorylation of ERK (p-ERK and the transcription factor cAMP response element-binding protein (p-CREB increased in the spinal cord of CIBP rats, which was attenuated by intrathecal injection of fluorocitrate or U0126. Conclusions The ERK inhibitors could have a useful role in CIBP management, because the same target is expressed in various cells at different times.

However, the role of spinal cells and the ERK/MAPK pathway in cancer-induced bone pain (CIBP) remains poorly understood. The present study analyzed activation of spinal cells and the ERK/MAPK pathway in a rat model of bone cancer pain. A Sprague Dawley rat model of bone cancer pain was established and the model was evaluated by a series of tests. Moreover, fluorocitrate (reversible glial metabolic inhibitor) and U0126 (a MEK inhibitor) was administered intrathecally. Western blots and double immunofluorescence were used to detect the expression and location of phosphorylation of ERK (p-ERK). Our studies on pain behavior show that the time between day 6 and day 18 is a reasonable period ("time window" as the remaining stages) to investigate bone cancer pain mechanisms and to research analgesic drugs. Double-labeling immunofluorescence revealed that p-ERK was sequentially expressed in neurons, microglia, and astrocytes in the L4-5 superficial spinal cord following inoculation of Walker 256 cells. Phosphorylation of ERK (p-ERK) and the transcription factor cAMP response element-binding protein (p-CREB) increased in the spinal cord of CIBP rats, which was attenuated by intrathecal injection of fluorocitrate or U0126. The ERK inhibitors could have a useful role in CIBP management, because the same target is expressed in various cells at different times.

    Full Text Available Metastatic renal cell cancer (RCC is a malignant disease without curative treatment. These patients are usually symptomatic and desperate for effective palliative treatment. Radiotherapy, chemotherapy, and hormonal therapy are not effective in these patients. A multimodal approach consisting of cytoreductive nephrectomy, systemic therapy (which includes cytokines or targeted molecules, and metastasectomy have been shown to be useful in prolonging the survival and improving the quality of life in a select group of patients with metastatic renal cancer. Patients with oligometastatic disease, good performance status, and delayed presentation of the secondaries have better results following this integrated approach. Although there is some controversy regarding the order in which nephrectomy and systemic therapy are to be instituted, well-controlled studies like the South West Oncology Group and European organization research and treatment of cancer have shown that upfront nephrectomy gives better survival compared to neoadjuvant systemic therapy followed by nephrectomy. This order is the standard presently. Of late, with better understanding of the genetic basis and the biology of the various subtypes of renal cell carcinoma, targeted molecular therapies have emerged as an equally effective alternative therapy to cytokines. Recent reports have proven that targeted therapy is more effective with comparable side effects. Metastasectomy in a subgroup of patients improves survival and quality of life specifically in those with lung secondaries and painful bone metastases.

  19. Microenvironment Stimuli HGF and Hypoxia Differently Affected miR-125b and Ets-1 Function with Opposite Effects on the Invasiveness of Bone Metastatic Cells: A Comparison with Breast Carcinoma Cells

    Full Text Available We examined the influence of microenvironment stimuli on molecular events relevant to the biological functions of 1833-bone metastatic clone and the parental MDA-MB231 cells. (i In both the cell lines, hepatocyte growth factor (HGF and the osteoblasts’ biological products down regulated nuclear Ets-1-protein level in concomitance with endogenous miR-125b accumulation. In contrast, under hypoxia nuclear Ets-1 was unchanged, notwithstanding the miR-125b increase. (ii Also, the 1833-cell invasiveness and the expression of Endothelin-1, the target gene of Ets-1/HIF-1, showed opposite patterns under HGF and hypoxia. We clarified the molecular mechanism(s reproducing the high miR-125b levels with the mimic in 1833 cells. Under hypoxia, the miR-125b mimic maintained a basal level and functional Ets-1 protein, as testified by the elevated cell invasiveness. However, under HGF ectopic miR-125b downregulated Ets-1 protein and cell motility, likely involving an Ets-1-dominant negative form sensible to serum conditions; Ets-1-activity inhibition by HGF implicated HIF-1α accumulation, which drugged Ets-1 in the complex bound to the Endothelin-1 promoter. Altogether, 1833-cell exposure to HGF would decrease Endothelin-1 transactivation and protein expression, with the possible impairment of Endothelin-1-dependent induction of E-cadherin, and the reversion towards an invasive phenotype: this was favoured by Ets-1 overexpression, which inhibited HIF-1α expression and HIF-1 activity. (iii In MDA-MB231 cells, HGF strongly and rapidly decreased Ets-1, hampering invasiveness and reducing Ets-1-binding to Endothelin-1 promoter; HIF-1α did not form a complex with Ets-1 and Endothelin-1-luciferase activity was unchanged. Overall, depending on the microenvironment conditions and endogenous miR-125b levels, bone-metastatic cells might switch from Ets-1-dependent motility towards colonization/growth, regulated by the balance between Ets-1 and HIF-1.

    Intravenous bisphosphonates have been used in metastatic breast cancer patients to reduce pathologic bone fracture and bone pain. However, necrosis of the jaw has been reported in those who received intravenous bisphosphonates. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is caused by dental extraction, dental implant surgery, and denture wearing; however, it occurs spontaneously. The purpose of this study was to report BRONJ in metastatic breast cancer patients. Consecutive 25 female patients were referred from the Department of Oncology from 2008 to 2014 for jaw bone discomfort. Staging of breast cancer, history of bisphosphonate infusion, etiology of BRONJ, and treatment results were reviewed. Average age of the patients was 55.4 years old (38-74). Twelve maxillae and 16 mandibles were involved. Conservative treatments such as irrigation, antibiotic medication, analgesics, and oral gargle were applied for all patients for the initial treatment. Patients who had sequestrum underwent debridement and primary closure. The etiologies of BRONJ were dental extraction (19 cases), dental implant (2 cases), and endodontic treatment (1 case). However, three patients did not have any risk factors to cause BRONJ. Three patients died of progression of metastasis during follow-up periods. Surgical debridement was performed in 21 patients with success in 18 patients. Three patients showed recurred bone exposure and infection after operation. Prevention of the BRONJ is critical in metastatic breast cancer patients. Conservative treatment to reduce pain, discomfort, and infection is recommended for the initial therapy. However, if there is a sequestrum, surgical debridement and primary closure is the key to treat the BRONJ.

    Evidence to support the use of bone hydroxydiphosphonate (HDP) single photon emission computed tomography (SPECT/CT) in patients with facetogenic low back pain (LBP) is still limited. In this study we compared the scintigraphic patterns on bone SPECT/CT with the degree of structural facet joint (FJ) degeneration on CT in patients with LBP. Ninety-nine consecutive patients with LBP were prospectively evaluated. Patients with known or suspected malignancy, trauma, infectious processes, chronic inflammatory diseases, and previous surgery were excluded. The effect of LBP on the daily quality of life was assessed with the Oswestry disability index (ODI). The Pathria grading system was used to score FJ degeneration on CT scans. The correlation between the degree of FJ degeneration and osteoblastic activity on SPECT/CT was analyzed with Kappa statistics. Ninety-nine patients were included (59 female, mean age 56.2 years). The mean ODI score was 38.5% (range, 8% to 72%). In all, 792 FJ (L2-3 to L5-S1) were examined. Of the FJs, 49.6% were Pathria grade 0-1 (normal to mild degeneration) on CT, 35% were grade 2 (moderate degeneration), and 16% were grade 3 (severe degeneration). Sixty-seven percent of the patients had scintigraphically active FJs on SPECT/CT. Sixty-nine percent of Pathria grade 3 FJs were scintigraphically active; 5.5% and 16.8% of Pathria grade 0-1 and Pathria grade 2, respectively, were active. Of the metabolically active FJs, 71.4% were at the L4-5/L5-S1 levels. The ability of SPECT/CT to precisely localize scintigraphically active FJs may provide significant improvement in the diagnosis and treatment of patients with LBP. In this study we demonstrate that in >40% of FJs, the scintigraphic patterns on SPECT/CT did not correlate with the degree of degeneration on CT. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Bone marrow sampling remains essential in the evaluation of hematopoietic and many non-hematopoietic disorders. One common limitation to these procedures is the discomfort experienced by patients. To address whether a Powered biopsy system could reduce discomfort while providing equivalent or better results, we performed a randomized trial in adult volunteers. Twenty-six subjects underwent bilateral biopsies with each device. Core samples were obtained in 66.7% of Manual insertions; 100% of Powered insertions (P=0.002. Initial mean biopsy core lengths were 11.1±4.5 mm for the Manual device; 17.0±6.8 mm for the Powered device (P<0.005. Pathology assessment for the Manual device showed a mean length of 6.1±5.6 mm, width of 1.0±0.7 mm, and volume of 11.0±10.8 mm3. Powered device measurements were mean length of 15.3±6.1 mm, width of 2.0±0.3 mm, and volume of 49.1±21.5 mm3 (P<0.001. The mean time to core ejection was 86 seconds for Manual device; 47 seconds for the Powered device (P<0.001. The mean second look overall pain score was 33.3 for the Manual device; 20.9 for the Powered (P=0.039. We conclude that the Powered biopsy device produces superior sized specimens, with less overall pain, in less time.

    Background and purpose: Trans-Tasman Radiation Oncology Group 96.05 is a prospective randomized controlled trial comparing a single 8 Gy with 20 Gy in five fractions of radiotherapy (RT) for neuropathic pain due to bone metastases. This paper summarizes the quality assurance (QA) activities for the first 234 patients (accrual target 270). Materials and methods: Independent audits to assess compliance with eligibility/exclusion criteria and appropriateness of treatment of the index site were conducted after each cohort of approximately 45 consecutive patients. Reported serious adverse events (SAEs) in the form of cord/cauda equina compression or pathological fracture developing at the index site were investigated and presented in batches to the Independent Data Monitoring Committee. Finally, source data verification of the RT prescription page and treatment records was undertaken for each of the first 234 patients to assess compliance with the protocol. Results: Only one patient was found conclusively not to have genuine neuropathic pain, and there were no detected 'geographical misses' with RT fields. The overall rate of detected infringements for other eligibility criteria over five audits (225 patients) was 8% with a dramatic improvement after the first audit. There has at no stage been a statistically significant difference in SAEs by randomization arm. There was a 22% rate of RT protocol variations involving ten of the 14 contributing centres, although the rate of major dose violations (more than ±10% from protocol dose) was only 6% with no statistically significant difference by randomization arm (P=0.44). Conclusions: QA auditing is an essential but time-consuming component of RT trials, including those assessing palliative endpoints. Our experience confirms that all aspects should commence soon after study activation

    Bone marrow aspiration and biopsy (BMAB) is painful when performed with only local anesthetic. Our objective was to determine whether viewing nature scenes and listening to nature sounds can reduce pain during BMAB. This was a randomized, controlled clinical trial. Adult patients undergoing outpatient BMAB with only local anesthetic were assigned to use either a nature scene with accompanying nature sounds, city scene with city sounds, or standard care. The primary outcome was a visual analog scale (0-10) of pain. Prespecified secondary analyses included categorizing pain as mild and moderate to severe and using multiple logistic regression to adjust for potential confounding variables. One hundred and twenty (120) subjects were enrolled: 44 in the Nature arm, 39 in the City arm, and 37 in the Standard Care arm. The mean pain scores, which were the primary outcome, were not significantly different between the three arms. A higher proportion in the Standard Care arm had moderate-to-severe pain (pain rating ≥4) than in the Nature arm (78.4% versus 60.5%), though this was not statistically significant (p = 0.097). This difference was statistically significant after adjusting for differences in the operators who performed the procedures (odds ratio = 3.71, p = 0.02). We confirmed earlier findings showing that BMAB is poorly tolerated. While mean pain scores were not significantly different between the study arms, secondary analyses suggest that viewing a nature scene while listening to nature sounds is a safe, inexpensive method that may reduce pain during BMAB. This approach should be considered to alleviate pain during invasive procedures.

    Full Text Available Prostate cancer is common in older patients. Rarity in younger population limits the study of natural history and prognosis in this population. Most of the published data has reported poor outcome in younger patients with metastatic prostate cancer. Here, we report a case of prostate cancer in 28-year-old male who presented with bone metastasis. After bilateral inguinal orchidectomy, he was started on anti-androgen therapy and received palliative radiotherapy for bone metastasis. There was only a slight decrease in prostate-specific antigen (PSA level and pelvic disease post treatment. Subsequently, he was started on opioid analgesics (by World Health Organization, WHO, step ladder in view of persistent pain. The index case is being presented for its rarity and probable poor outcome in young patients and to stress on the fact that the possibility of primary prostatic adenocarcinoma should be investigated in a male presenting with bone metastasis irrespective of the age.

    The physical and biological attributes of 117m Sn(4+)-DTPA indicate that it should be an effective agent for palliative therapy of painful bony metastatic disease. The aim of this study was to evaluate whether or not this agent could effectively reduce pain while sparing the hemopoietic marrow from adverse effects. Fifteen patients (10 males and 5 females) with painful bony metastases from various primary cancers were included in the study. Seven patients received 1.22 to 3.11 MBq/kg of 117m Sn intravenously (Group 1) and eight patients received 4.85 to 5.77 MBq/kg (Group 2). All but one were treated as outpatients and followed for a minimum of 2 mo. In the first group, pain relief was nonassessable in four patients because of death or additional treatment of soft-tissue disease by another modality. One patient had no relief of pain, one had complete relief of pain and one had transient relief of pain. No myelotoxicity was observed. For Group 2, three patients achieved complete relief of pain, two good relief, two partial relief and one began to experience pain relief when he suffered a pathological fracture 2 mo most-treatment. None of these patients had myelotoxicity. Tin-117m(4+)-DTPA can reduce pain from metastatic disease to bone without inducing adverse reactions related to bone marrow. Further studies are needed to assess tolerance levels for the bone marrow and to evaluate response rates and duration of effect. 6 refs., 4 figs., 4 tabs

    Metastatic castration-resistant prostate cancer (mCRPC) often involves bone, and bone-targeted therapy (BTT) has become part of the overall treatment strategy. Investigation of outcomes for concomitant BTT in a post hoc analysis of the COU-AA-302 trial, which demonstrated an overall clinical benefit of abiraterone acetate (AA) plus prednisone over placebo plus prednisone in asymptomatic or mildly symptomatic chemotherapy-naïve mCRPC patients. This report describes the third interim analysis (prespecified at 55% overall survival [OS] events) for the COU-AA-302 trial. Patients were grouped by concomitant BTT use or no BTT use. Radiographic progression-free survival and OS were coprimary end points. This report describes the third interim analysis (prespecified at 55% OS events) and involves patients treated with or without concomitant BTT during the COU-AA-302 study. Median follow-up for OS was 27.1 mo. Median time-to-event variables with 95% confidence intervals (CIs) were estimated using the Kaplan-Meier method. Adjusted hazard ratios (HRs), 95% CIs, and p values for concomitant BTT versus no BTT were obtained via Cox models. While the post hoc nature of the analysis is a limitation, superiority of AA and prednisone versus prednisone alone was demonstrated for clinical outcomes with or without BTT use. Compared with no BTT use, concomitant BTT significantly improved OS (HR 0.75; p=0.01) and increased the time to ECOG deterioration (HR 0.75; pAA was similar to that reported for AA in the overall intent-to-treat population. Osteonecrosis of the jaw (all grade 1/2) with concomitant BTT use was reported in AA with concomitant BTT was safe and well tolerated in men with chemotherapy-naïve mCRPC. The benefits of AA on clinical outcomes were increased with concomitant BTT. Treatment of advanced prostate cancer often includes bone-targeted therapy. This post hoc analysis showed that in patients with advanced prostate cancer who were treated with abiraterone acetate and

    Increased knee pain at the time of anterior cruciate ligament reconstruction may potentially predict more difficult rehabilitation, prolonged recovery, and/or be predictive of increased knee pain at 2 years. A bone bruise and/or other preoperative factors are associated with more knee pain/symptoms at the time of index anterior cruciate ligament reconstruction, and the presence of a bone bruise would be associated with specific demographic and injury-related factors. Cohort study (prevalence); Level of evidence, 2. In 2007, the Multicenter Orthopaedic Outcomes Network (MOON) database began to prospectively collect surgeon-reported magnetic resonance imaging bone bruise status. A multivariable analysis was performed to (1) determine if a bone bruise, among other preoperative factors, is associated with more knee symptoms/pain and (2) examine the association of factors related to bone bruise. To evaluate the association of a bone bruise with knee pain/symptoms, linear multiple regression models were fit using the continuous scores of the Knee injury and Osteoarthritis Outcome Score (KOOS) symptoms and pain subscales and the Short Form 36 (SF-36) bodily pain subscale as dependent variables. To examine the association between a bone bruise and risk factors, a logistic regression model was used, in which the dependent variable was the presence or absence of a bone bruise. Baseline data for 525 patients were used for analysis, and a bone bruise was present in 419 (80%). The cohort comprises 58% male patients, with a median age of 23 years. The median Marx activity level was 13. Factors associated with more pain were higher body mass index (P pain at the time of index anterior cruciate ligament reconstruction. None of the factors included in the SF-36 bodily pain model were found to be significant. After controlling for other baseline factors, the following factors were associated with a bone bruise: younger age (P = .034) and not jumping at the time of injury (P = .006

    Full Text Available Abstract Background Chronic low back pain (CLBP experienced in middle-age may have important implications for vertebral bone health, although this issue has not been investigated as a primary aim previously. This study investigated the associations between CLBP and dual energy X-ray absorptiometry (DXA-derived vertebral bone mineral measures acquired from postero-anterior and lateral-projections, among community-dwelling, middle-aged adults. Methods Twenty-nine adults with CLBP (11 male, 18 female and 42 adults with no history of LBP in the preceding year (17 male, 25 female were evaluated. Self-reported demographic and clinical data were collected via questionnaires. Areal bone mineral density (aBMD was measured in the lumbar spine by DXA. Apparent volumetric (ap.v BMD in the lumbar spine was also calculated. Multiple linear regression models were used to examine associations between study group (CLBP and control and vertebral DXA variables by gender, adjusting for height, mass and age. Results There was no difference between groups by gender in anthropometrics or clinical characteristics. In the CLBP group, the mean (SD duration of CLBP was 13.3 (10.4 years in males and 11.6 (9.9 years in females, with Oswestry Disability Index scores of 16.2 (8.7% and 15.4 (9.1%, respectively. Males with CLBP had significantly lower adjusted lateral-projection aBMD and lateral-projection ap.vBMD than controls at L3 with mean differences (standard error of 0.09 (0.04 g/cm2 (p = 0.03 and 0.02 (0.01 g/cm3 (p = 0.04. These multivariate models accounted for 55% and 53% of the variance in lateral-projection L3 aBMD and lateral-projection L3 ap.vBMD. Conclusions CLBP in males is associated with some lumbar vertebral BMD measures, raising important questions about the mechanism and potential clinical impact of this association.

  13. Metastatic breast carcinoma uncovered in an otherwise unremarkable “random colon biopsy”

    Directory of Open Access Journals (Sweden)

    Mike Black

    2016-06-01

    Full Text Available Breast cancer is one of the most devastating cancers afflicting women, being a main cause of cancer related death. Approximately 50% of these patients have developed regional or distant metastases at the time of diagnosis; hence, an early diagnosis and surgery with indicated neoadjuvant therapy are crucial in eradicating this disease and improving patient survival. A significant percentage of patients, even after initial satisfactory tumor removal, still face the threat of metastatic diseases which could plague a wide spectrum of body sites such as bones, lungs, central nervous system, liver and gastrointestinal tract (mostly upper gastrointestinal locations. Colonic and anorectal involvement by metastatic breast cancer has been less frequently reported in disseminated diseases. Typically, metastatic disease presents as a mass, enteric stenosis, or obstruction. Rare cases, however, may not form an endoscopically or radiologically recognizable lesion, and thus could be overlooked. Here we report a unique case of random colon biopsies in a patient presenting with epigastric pain, whose stomach biopsy showed Helicobacter pylori-associated chronic active gastritis. No colonoscopic lesion was present; however, microscopic examination of the “random biopsy” revealed scattered single and small clusters of tumor cells involving the lamina propria of the colonic mucosa, morphologically and immunophenotypically consistent with metastatic disease from breast carcinoma. The clinical presentation and histopathology of the case were reviewed and compared with limited cases reported in the literature. We conclude that high levels of suspicion and alertness are essential to identify occult microscopic gastrointestinal metastatic breast cancer in the absence of a grossly appreciable lesion.

    To retrospectively evaluate the efficacy and safety of microwave ablation (MWA) combined with osteoplasty in lung cancer patients with painful extraspinal bone metastases. From January 2011 to July 2014, 26 lung cancer patients with 33 painful extraspinal bone metastases underwent percutaneous MWA combined with osteoplasty. 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.

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.

    Full Text Available The contents of this data in brief are related to the article titled “Matrix Rigidity Regulates the Transition of Tumor Cells to a Bone-Destructive Phenotype through Integrin β3 and TGF-β Receptor Type II”. In this DIB we will present our supplemental data investigating Integrin expression, attachment of cells to various adhesion molecules, and changes in gene expression in multiple cancer cell lines. Since the interactions of Integrins with adsorbed matrix proteins are thought to affect the ability of cancer cells to interact with their underlying substrates, we examined the expression of Integrin β1, β3, and β5 in response to matrix rigidity. We found that only Iβ3 increased with increasing substrate modulus. While it was shown that fibronectin greatly affects the expression of tumor-produced factors associated with bone destruction (parathyroid hormone-related protein, PTHrP, and Gli2, poly-l-lysine, vitronectin and type I collagen were also analyzed as potential matrix proteins. Each of the proteins was independently adsorbed on both rigid and compliant polyurethane films which were subsequently used to culture cancer cells. Poly-l-lysine, vitronectin and type I collagen all had negligible effects on PTHrP or Gli2 expression, but fibronectin was shown to have a dose dependent effect. Finally, altering the expression of Iβ3 demonstrated that it is required for tumor cells to respond to the rigidity of the matrix, but does not affect other cell growth or viability. Together these data support the data presented in our manuscript to show that the rigidity of bone drives Integrinβ3/TGF-β crosstalk, leading to increased expression of Gli2 and PTHrP.

  17. A Case of Disease Improvement after Treatment with Everolimus plus Exemestane in a Patient with Hormone Receptor-Positive Metastatic Breast Cancer with Bone Metastases

    Full Text Available Breast cancer is one of the most frequently diagnosed cancers and a leading cause of death in women worldwide. Despite significant advances in the treatment of hormone receptor-positive breast cancer, tumor metastasis occurs frequently and is associated with poor long-term prognosis. The mammalian target of rapamycin (mTOR pathway plays a central role in cancer cell growth, proliferation, and resistance to endocrine therapies. Therefore, mTOR inhibitors such as everolimus in combination with nonsteroidal aromatase inhibitors might reverse endocrine resistance and improve clinical outcomes in patients. Here, we report on a case of infiltrating lobular carcinoma of the breast with metastases to the bone. Histopathologic analysis showed that the patient was estrogen and progesterone receptor positive and human epidermal growth factor-2 negative. This case represents the clinical spectrum of complications caused by metastasis: the patient experienced a considerable amount of skeletal-related complications, had previously received chemotherapy, and experienced disease progression while taking nonsteroidal aromatase inhibitors. After treatment with oral everolimus 10 mg daily plus oral exemestane 25 mg daily, the patient's disease was ameliorated. Combination therapy was well tolerated, with minimal adverse effects that were manageable with concomitant medications. Although further analyses in larger populations are necessary, the addition of everolimus to exemestane might provide an effective new treatment option for patients with bone metastasis.

    To identify frail and pre-frail patients in a group of patients older than 60 years. The phenotype model of Fried's method was used to identify frailty and pre-frailty in total of 78 participants. Cognitive ability and psychosocial function tests were also given to 59 of the 78 patients. Prevalence of frailty and pre-frailty was 14.1% (11/78) and 46.2% (36/78), respectively. Of the 5 phenotype variables, weak grip strength was the most commonly seen variable with 53.8% of all participants and 100% in the frail group. Low energy expenditure, however, was not self-reported by any participant in the current study (0%). Prevalence of frailty in the present study is associated with chronological age. The current study indicates that 4 phenotypic variables (unintentional weight loss, self-reported exhaustion, gait speed and grip strength) contribute to the development to frailty, and that cognitive impairment and psychosocial frailty also predict frailty or pre-frailty in the patients older than 60 years old irrespective of chronic pain or osteoarthritis. The findings of the current study suggest frailty and pre-frailty are common in senior Chinese patients with chronic diseases. Recognition and identification of frailty in a rehabilitation clinic or hospital might help physicians to provide appropriate counseling to patients and families about adverse outcomes of certain treatments such as surgery, and could optimize management of coexisting chronic diseases that might contribute to or be affected by frailty.

    Purpose: The aim of this study is to show the utility of vertebroplasty in the treatment of some types of back pain. Vertebroplasty is a venous embolisation of the vertebral body performed under computed tomography (CT) or fluoroscopy guidance with transpedicular, anterolateral, intercostovertebral or posterolateral approach with acrylic element. Materials and methods: We report our experience in 85 patients suffering from low back and thoracic pain and treated with percutaneous vertebroplasty owing to osteoporotic vertebral compression fractures, vertebral haemangiomas or secondary lytic lesions of the spine. Patient selection was performed on the basis of physical examination, magnetic resonance or less frequently, with bone scan. CT has a minor role in selected cases to evaluate the integrity of the posterior wall. We treated 55 patients affected by acute osteoporotic vertebral compression fracture, 10 patients with vertebral haemangioma and 20 patients with metastatic lesions. The patients were placed in the prone position and the procedure was performed under fluoroscopy guidance in 80 patients and under CT guidance in 5 patients affected by metastatic lesions. In no case was phlebography performed before the treatment. The approach adopted was bilateral in 45 patients and unilateral in the remaining 30 cases. Injection with a low viscosity cement was performed under fluoroscopy guidance with extreme precision in all cases. The amount of cement injected ranged from 4 ml (thoracic level) up to 12 ml (lumbar level). Results: The results were better for osteoporotic cases (95%) and patients with vertebral haemangioma (90%) than with metastatic lesions (77%), with improvement within 24-72 hours after the treatment. We noted asymptomatic cement leakage in 39 cases but only in 2 cases was there an acute radiculopathy due to epidural cement leakage, which was treated and resolved medically in 1 month. At follow-up no cases were noted of fractures of vertebral bodies

    A 71-year old patient suffering from untreated non-insulin-dependent diabetes presented anti-inflammatory drug-resistant lumbalgia with referred inguinal pain either on the right or left side, corresponding to the first signs of septicemia due to staphylococcus aureus, with urinary onset. Despite specific antibiotic treatment, pulmonary, cardiac and neurological complications followed. Simultaneous investigations by MRI and bone scintigraphy performed in the remitting patient showed multiple septic metastatic localization in the soft tissues and bones. It was hence necessary to pursue the antibiotic therapy to avoid relapses. (author)

    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

    Full Text Available Abstract Background Malignant arthritis is a rare manifestation of metastatic disease. We describe the case of a previously well 28 year old man in whom hip pain was the presenting symptom of disease. We describe the case and discuss the aetiology of colorectal cancer in young patients. We then review the literature and discuss the investigation and management of malignant joint arthritis. Case presentation We present the case of a 28 year old man who presented to the emergency department with an acute monoarthritis of the hip. He had an unremarkable past medical history and was systemically well. A diagnosis of malignant joint effusion was reached after a heightened index of clinical suspicion, magnetic resonance imaging and cytological evaluation of the synovial fluid. Computed tomography and bone scan confirmed widespread metastatic disease from a primary colonic adenocarcinoma. The patient tolerated three cycles of oxaliplatin and capecitabine but died 4 months after presentation. Conclusion The metastatic spread of cancer to the joint and the synovium is one of the rarest manifestations of malignant disease and has not been previously reported as the presenting symptom of disease. The diagnosis is a difficult one to reach and is associated with a poor prognosis. This case illustrates the importance of thorough investigation in reaching this diagnosis and entertaining the possibility in individuals who do not respond to conventional management of acute monoarthritis, even in young patients and individuals who do not display any other symptoms of disease.

    Thermal ablation is an effective, minimally invasive alternative to conventional therapies in the palliation of painful musculoskeletal metastases and an emerging approach to obtain local tumor control in the setting of limited metastatic disease. Various thermal ablation technologies have been applied to bone and soft tissue tumors and may be used in combination with percutaneous cement instillation for skeletal lesions with or at risk for pathologic fracture. This article reviews current practices of percutaneous ablation of musculoskeletal metastases with an emphasis on radiofrequency ablation and cryoablation of painful skeletal metastases. © 2013 Elsevier Inc.

    Efficacy of palliative and prophylactic radiotherapies for metastatic bone pain and pathological fracture was investigated in 14 patients with long bone metastases. Irradiation sites were the femur in 10 patients, the humerus in 2, the radius in one, and the tibia in one. Radiographs showed osteolytic lesion in 13 patients and osteoblastic lesion in one. A total dose of 48.6 Gy to 87.3 Gy was delivered in daily fractional doses of 2 Gy (one patient), 2.5 Gy (3), 3 Gy (6), 4 Gy (2) and 5 Gy (2), 5 days a week. For 13 patients, except for one death within one month after the completion of irradiation, pain relief was attained. Of these patients, 7 (54%) had complete pain relief. In one patient, pathological fracture occurred as early as 10 days after the beginning of irradiation when irradiation efficacy was not attained. In none of the 13 others, was pathological fracture encountered. No side effects were seen at all during or after irradiation. Radiation therapy was an extremely effective means for managing patients with long bone metastases in terms of its palliative and prophylactic role. (N.K.)

    Although the three phase bone scan (TBPS) is one of the widely used imaging studies for diagnosing complex regional pain syndrome type 1 (CRPS 1), there is some controversy regarding the TPBS image criteria for CRPS 1. In this study, we modified the image criteria using image pattern and quantitative analysis in the patients diagnosed using the most recent consensus clinical diagnostic criteria. The study included 140 patients with suspected CRPS 1 (CRPS 1, n=79; non CRPS, n=61; mean age 39{+-}15 years) who underwent TPBS. The clinical diagnostic criteria for CRPS 1 revised by the Budapest consensus group were used for confirmative diagnosis. Patients were classified according to flow/pool and delayed uptake (DU) image patterns, and the time interval between the initiating event and TPBS (TI{sup eventscan)}. Quantitative analysis for lesion to contralateral ratio (LCR) was performed. Modified TPBS image criteria were created and evaluated for optimal diagnostic performance. Both increased and decreased periarticular DU were significant image findings for CRPS 1 (CRPS 1 positive rate=73% in the increased DU group, 75% in the decreased DU group). The TI{sup eventscand}id not differ significantly between the different image pattern groups. Quantitative analysis revealed an LCR of 1.43 was the optimal cutoff value for CRPS 1 and diagnostic performance was significantly improved in the increased DU group (area under the curve=0.732). Given the modified image criteria, the sensitivity and specificity of TPBS for diagnosing CRPS 1 were 80% and 72%, respectively. Optimally modified TPBS image criteria for CRPS 1 were suggested using image pattern and quantitative analysis. With the criteria, TPBS is an effective imaging study for CRPS 1 even with the most recent consensus clinical diagnostic criteria.

    The role of dopaminergic system in the development of rheumatoid arthritis-related pain, a major symptom in this disease, has not been explored. Therefore, the anti-nociceptive effect of mazindol, a dopamine uptake inhibitor, was evaluated in a model of complete Freund's adjuvant (CFA)-induced arthritis. Furthermore, as studies have shown that the dopaminergic system regulates bone metabolism, the effect of mazindol on bone mass and microarchitecture was determined. Adult ICR male mice received intra-articular injections of either CFA or saline into the right knee joint every week. Spontaneous pain-like behaviors (flinching and guarding) and locomotor activity were assessed at day 26 post-first CFA, following which, a single intraperitoneally (i.p.) administered dose of mazindol was given (1, 3 and 10 mg/kg). Then, the antinociceptive effect of a repeated administration of 3 mg/kg mazindol (daily, i.p.; day 15-day 26) was evaluated. Additionally, at day 26, the participation of D1-like, D2-like or opioid receptors in the antinociceptive effect of mazindol was evaluated. The effect of mazindol on bone density and microarchitecture was evaluated by micro-computed tomography. Acute administration of mazindol decreased the spontaneous pain-like behaviors in a dose-dependent manner without reducing the knee edema. However, mazindol at 10 mg/kg significantly increased the locomotor activity; therefore, 3 mg/kg mazindol was used for further studies. Repeated administration of 3 mg/kg mazindol significantly decreased the pain-like behaviors without modifying locomotor activity. The antinociceptive effect of mazindol was blocked by administration of a D2-like receptor antagonist (haloperidol), but not by administration of D1-like receptor antagonist (SCH 23390) or an opioid receptor antagonist (naloxone). Repeated administration of mazindol did not significantly modify the density and microarchitecture of periarticular bone of the arthritic and nonarthritic knee joints

    Osteosarcoma (OS) is the most common pediatric bone tumor and is associated with the emergence of pulmonary metastasis. Unfortunately, the mechanistic basis for metastasis remains unclear. Tumor-derived extracellular vesicles (EVs) have been shown to play critical roles in cell-to-cell communication and metastatic progression in other cancers, but their role in OS has not been explored. We show that EVs secreted by cells derived from a highly metastatic clonal variant of the KHOS cell line can be internalized by a poorly metastatic clonal variant of the same cell line and induce a migratory and invasive phenotype. This horizontal phenotypic transfer is unidirectional and provides evidence that metastatic potential may arise via interclonal co-operation. Proteomic analysis of the EVs secreted by highly metastatic OS clonal variants results in the identification of a number of proteins and G-protein coupled receptor signaling events as potential drivers of OS metastasis and novel therapeutic targets. Finally, multiphoton microscopy with fluorescence lifetime imaging in vivo, demonstrated a preferential seeding of lung tissue by EVs derived from highly metastatic OS clonal variants. Thus, we show that EVs derived from highly metastatic clonal variants of OS may drive metastatic behaviour via interclonal co-operation and preferential colonization of the lungs.

    Bone metastases are rare in primary hepatocellular carcinoma (HCC). Spinal cord compression (SCC) due to bone metastases occur commonly in patients with lung and breast carcinomas, and metastatic HCC is an unusual cause of SCC. Spinal cord compression is an oncologic emergency and treatment delays can lead to irreversible consequences. Thus, the awareness that SCC could be a potential complication of bone metastases due to HCC is of significance in initiation of early treatment that can improve the quality of life and survival of the patients, if diagnosed earlier. This paper describes four cases of primary HCC with varied manifestations of SCC due to bone metastases. The first patient presented primarily with the symptoms of bone pains corresponding to the bone metastases sites rather than symptoms of associated hepatic pathology and eventually developed SCC. The second patient, diagnosed as having HCC, developed extradural SCC leading to paraplegia during the course of illness, for which he underwent emergency laminectomy with posterior fixation. The third patient developed SCC soon after the primary diagnosis and had to undergo emergency laminectomy. Post laminectomy he had good neurological recovery. The Fourth patient presented primarily with radicular pains rather than frank paraplegia as the first manifestation of SCC. PMID:16937544

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    2008-07-01

    Full Text Available Abstract Introduction Shoulder-hand syndrome is a relatively rare clinical entity classified as a complex regional pain syndrome type 1 and consisting essentially of a painful 'frozen shoulder' with disability, swelling, vasomotor or dystrophic changes in the homolateral hand. The pathophysiology is not completely clear but a predominant 'sympathetic' factor affecting the neural and vascular supply to the affected parts seems to be involved. Shoulder-hand syndrome has been related to many surgical, orthopedic, neurological and medical conditions; it is more often seen after myocardial infarction, hemiplegia and painful conditions of neck and shoulder, such as trauma, tumors, cervical discogenic or intraforaminal diseases and shoulder calcific tendinopathy, but has also been associated with herpetic infections, brain and lung tumors, thoracoplasty and drugs including phenobarbitone and isoniazid. The diagnosis of shoulder-hand syndrome is primarily clinical, but imaging studies, particularly bone scintigraphy, may be useful to exclude other disorders. Case presentation We report the case of a 67-year-old woman who presented with shoulder-hand syndrome as the initial manifestation of gastric cancer which had metastasized to bone. Conclusion Wider investigations are advisable in patients with atypical shoulder-hand syndrome. To the best of the authors' knowledge this is the first case of shoulder-hand syndrome associated with metastatic gastric cancer.

    Sarcomas are cancers arising from the mesenchymal layer that affect children, adolescents, young adults, and adults. Although most sarcomas are localized, many display a remarkable predilection for metastasis to the lungs, liver, bones, subcutaneous tissue, and lymph nodes. Additionally, many sarcoma patients presenting initially with localized disease may relapse at metastatic sites. While localized sarcomas can often be cured through surgery and often radiation, controversies exist over optimal management of patients with metastatic sarcoma. Combinations of chemotherapy are the most effective in many settings, and many promising new agents are under active investigation or are being explored in preclinical models. Metastatic sarcomas are excellent candidates for novel approaches with additional agents as they have demonstrated chemosensitivity and affect a portion of the population that is motivated toward curative therapy. In this paper, we provide an overview on the common sarcomas of childhood (rhabdomyosarcoma), adolescence, and young adults (osteosarcoma, Ewing sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor) and older adults (leiomyosarcoma, liposarcoma, and undifferentiated high grade sarcoma) in terms of the epidemiology, current therapy, promising therapeutic directions and outcome with a focus on metastatic disease. Potential advances in terms of promising therapy and biologic insights may lead to more effective and safer therapies; however, more clinical trials and research are needed for patients with metastatic sarcoma.
