    Every year in Europe and in USA, more than 60% of new cases of cancer are diagnosed at the patient's of more than 65 years with a mortality of more than 70%. Pain, is a major symptom which often accompanies cancer. It is always painful and intolerable, notably when pain is linked to bone metastases to elderly patients often poly pathological. In 1/3 of cases pain is present at the time of diagnosis of cancer and in 2/3 of cases at the advanced diseases. The bone metastases occupy the third place after the pulmonary and liver metastases. They are in order of frequency linked in breast cancer, the kidney and the prostate cancer. Bone metastases are at the origin of the loss of the elderly autonomy, with for consequence an impairment of quality of life. Validated tools are at now available to assess this pain. The different treatments offered in bone metastases pain are: the chemotherapy, the surgery, radiotherapy, bisphosphonates and analgesic treatment.

    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

    In Germany the incidence of breast cancer is about 85 and of prostate cancer about 50 new patients per 100.000 inhabitants/year. In about 80% of prostate cancer patients and 75% of breast cancer patients bone metastases are observed in autopsy. Most of these patients develop severe pain syndrome from bone metastases reducing quality of life during life time. Therapy of these patients should aim at adding life to the years not years to their life. The knowledge of metastatic cell biology, of cell-cell interaction and of tumor-cell, tumor cell-skeleton interaction may modify the therapeutic procedure. Already in 1940/41, Pecher treated a patient suffering from painful prostate cancer bone metastases administering 296 MBq 89 Strontium chloride. About 10 years later, Friedell introduced 32 Phosphorus for treatment of bone metastases from breast cancer. Today in Europe 3 radionuclides are approved for pain palliation therapy as shown in Table.1. Indication: - pain palliation therapy of bone metastases from prostate cancer ( 89 Sr and 186 Re); - pain palliation of all osteoblastic metastases independent from primary tumors ( 153 Sm). Contraindications: - pregnant and lactating females - myelosuppression ( 3 granulocytes; 3 platelets); - impaired renal function (urea >12 mmol/l; creatinine > 150 mmol/l) - incontinence; - acute or chronic spinal cord compression and/or brain metastases causing neurological symptoms; - disseminated intravascular coagulopathy. The recommended activities per treatment are: 89 Sr 150 MBq, 186 Re 1.295 MBq, and 153 Sm 37 MBq/kg BW. Shortly (6-8 weeks) prior to radionuclide therapy for pain palliation no high dose chemotherapy or large field radiation therapy should be performed. Stopping unlabelled bisphosphonate therapy prior to pain palliation therapy is not necessary. This radionuclide therapy may be repeated several time, the interval between tracer administration depends on blood cell count rate. The recommended intervals are for 89 Sr

    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

    For palliation of pain caused by bone metastases beta radiation isotope therapy was successful. As shown in experimental work on animals bone uptake of 90 Y with its shorter half-life is high when it is administered as a citrate complex. 90 Y can be eluted with high purity from a 90 Sr cow. The retention in man was found by whole-body counting to be higher than 80%. In preliminary trials on 16 patients the analgetic effect was the same as that of 89 Sr. The properties of 90 Y therapy are discussed. (orig.) [de

    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.)

    Palliative radiotherapy provides pain relief for patients with painful bone metastases. The practice among radiation oncologists as to whether a large single fraction is most effective, or whether multiple smaller fractions are preferable in providing the quickest, most durable pain relief is inconsistent. A literature review was completed to see if there is consensus about whether there is better pain response and control following single versus multiple fraction radiotherapy. The Pub Med search engine was used to find all reported studies comparing single and multiple fraction radiotherapy for painful bone metastases. Each article was reviewed according to specific criteria. A generalized conclusion was ascertained from each study and then compared. Among the studies reviewed, the consensus concluded that single fraction radiotherapy was the better choice for palliation of painful bone metastases. According to the literature reviewed, single fraction radiotherapy provides adequate pain relief with reasonable duration of pain response. (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.

    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

    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

    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.

    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.

    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

    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

    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.

    Full text: Intravenous injection of Strontium-89 (Sr-89) is an accepted palliative treatment for bone metastases. We evaluated the pain relief achieved with this radiopharmaceutical in patients with widespread painful bone metastases from prostate and breast cancers. Pain intensity on a 9-grade scale and use of narcotics was recorded before and after Sr-89 injection, and the ensuing palliative effect was divided into complete, partial and no response. The duration of response was also recorded. Thirty-five patients with widespread painful bone metastases were treated with Sr-89, of whom 22 had prostate and 13 breast cancers. Mean follow-up was 227 days, during which death was recorded for 32 patients. Fourteen patients (40%) had a complete response, 9 (26%) partial and 12 (34%) no response. In the 23 responding patients, mean duration of response was 6 months. In 17 patients the response was present until death. There was no significant relationship between pain response and patients' age or type of primary cancer. No side effects were recorded other than mild and temporary drop in white blood cell and platelet counts. Three patients with a complete response had a second injection of Sr-89 after progression of pain. One of these patients had a second partial response; the other 2 did not show a response to the second injection. The use of Sr-89 for treatment of widespread painful bone metastases from prostate and breast cancers in our department showed a 66% rate of response and a mean response duration of 6 months, with no significant side effects.

    Sixteen patients with painful bone metastases received single fraction radiotherapy of 8 Gy. Single fraction radiotherapy was effective in providing pain relief with response rate of 88.8%. There were no severe acute side effects. The therapeutic regimen was also safe and effective in patients with poor performance status and poor prognosis. Therefore single fraction radiotherapy should be considered to treat pain arising from bone metastases. (author)

    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

    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.

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

    The records of 158 patients irradiated for bone metastases were reviewed to evaluate the effectiveness of pain relief and to judge the effect of treatment on overall quality of life. Within 3 months 73% of the sites treated had pain relief, with 55 to 65% having sustained relief up to 1 year or death. Of patients surviving more than 3 months, 63% maintained a satisfactory quality of life and were able to take care of most personal needs. The median survival of all patients was 1 year from initial treatment for bone metastasis. Radiation dose and the primary tumor site do not seem to be significant prognostic factors for initial pain relief or quality of life

    Systemic use of radiopharmaceuticals is a recognised alternative method for the treatment of pain in patients with multiple bone metastases. 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 metastases 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. (author)

    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)

    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.

    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.)

    Full text: Bone metastases that develop in patients with advanced prostatic cancer often cause deep, unremitting pain adversely affecting quality of life, pathologic fracture, immobility, anxiety and depression. Currently, a number of therapies specifically targeted for the treatment of pain from bone metastases are available. These include analgesics, chemotherapy, hormonal therapy, surgery, external beam radiation and systemically administered radiopharmaceuticals. Strontium Chloride (89Sr - Metastron) injection has been used as systemically administered radio therapeutic agent for the palliation of osteoblastic skeletal metastases. It imitates the biodistribution of calcium invivo and is avidly taken up by bony metastases. Twenty-five known prostatic cancer patients with painful bone metastases were assessed following a single injection of 89Sr (2.0 MBq / Kg body weight). Six patients (24%) showed dramatic improvement, 9 patients (36%) have substantial improvement, 5 patients (20%) have some improvements while 5 patients (20%) did not have any improvement. These improvements were assessed in various scoring rates such as improvement in the intensity of pain, fall in the total and free PSA titre, regression in the demonstrated area of metastases in bone scan. The last group of 5 patients who do not show any improvement were also tried with second injection of 89Sr. These patients were followed-up with measurement of total platelets count, differential cell count (DC) and total leucocyte count. Two patients have moderate improvement in the pain relief and rest three patients were refractory to the multiple schedules of injection. We conclude that 89Sr has a significant effect in improving palliation of the distressing symptoms associated with prostate cancer as against the major drawback of external beam radiotherapy limits to the number of sites that can be treated at a time or recurrence at the treated site or new areas of bony pain requiring several hospital

    Objective: To estimate clinical curative efficacy and adverse reaction of 89 Sr-chloride therapy for palliation of pain from bone metastases in the older patients with prostate cancer. Methods: 48 cases of older patients with metastatic prostate cancer with bone pain were studied after androgen deprivation therapy, 89 Sr- chloride were administrated iv for the palliative treatment of metastatic bone pain. The curative effects in patients were investigated, including palliation of pain, change of metastatic focus, the tumor sign of PSA, and the adverse reaction. Results: After 89 Sr-chloride therapy, the total palliation rate was 89.6%, inefficiency rate was 10.4%, while metastatic focus and PSA decreased to some extent. No severe adverse reaction occurred. Conclusions: It is shown that the curative efficacy of acesodyne is evident after 89 Sr-chloride therapy in older patients suffering from bone metastase with prostate cancer. It is an effective therapeutic method for the palliation of pain from bone metastases especially to the older patients with multiple metastatases. (authors)

    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

    Twenty-five cases of bone metastases involving the cortex alone are reviewed. Seven patients had primary lung carcinoma, while 18 had primary tumors not previously reported to produce cortical bone metastases (tumors of the breast, kidney, pancreas, adenocarcinoma of unknown origin, multiple myeloma). Radiographically, these cortical lesions were well circumscribed, osteolytic, and produced soft-tissue swelling and occasional periosteal reaction. A recurrent pattern of metadiaphyseal involvement of the long bones of the lower extremity (particularly the femur) was noted, and is discussed. Findings reported in the literature, review, pathophysiology, and the role of skeletal radiographs, bone scans, and CT scans in evaluating cortical bone metastases are addressed

    Background: The effect of the palliative irradiation of bone metastases was explored in this retrospective analysis. The spectrum of primary tumor sites, the localization of the bone metastases and the fractionation schedules were analyzed with regard to palliation discriminating total, partial and complete pain response. Patients and Methods: One hundred seventy-six patients are included in this retrospective quantitative study from April 1992 to November 1993. Two hundred fifty-eight localizations of painful bone metastases were irradiated. The percentage of bone metastases of the total irradiated localizations in our department of radiotherapy in the Carite-Hospital, the primary tumor sites, the localizations and the different fractionation schedules were explored. The total, partial and complete pain response was analyzed in the most often used fractionation schedules and by primary tumor sites. Results: Eight per cent of all irradiated localizations in the observation period were bone metastases. There were irradiated bone metastases of 21 different tumor sites. Most of the primary tumor sites were breast cancer (49%), lung cancer (6%) and kidney cancer (6%). The most frequent site of metastases was the vertebral column (52%). The most often used fractionation schedules were: 4x5 Gy (32%), 10x3 Gy (18%), 6x5 Gy (9%), 7x3 Gy (7%), 10x2 Gy (5%) and 2x8 Gy. The total response rates in this fractionation schedules were 72%, 79%, 74%, 76%, 75% and 72%, the complete response rates were 35%, 32%, 30%, 35%, 33% and 33%. There were no significant differences between the most often irradiated primary tumor sites, the most frequent localizations and the palliation with regard to total, partial and complete pain response.

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

    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.

    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.

    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

    To evaluate the safety and efficacy of magnetic resonance guided focused ultrasound surgery (MRgFUS) in treatment for pain palliation of bone metastases. Eighty-one patients of painful bone metastases were volunteered to screen for this study in Shanghai General Hospital from June 2014 to February 2015. Twenty-three patients among them were treated by MRgFUS, who was more than 18-years old, having the ability to fully understand the informed consent of the research, suffering with pain of numeric rating scale (NRS) ≥ 4, non-received radiotherapy or chemotherapy for pain palliation of bone metastases in the past two weeks. The NRS, the standard question of Brief Pain Inventory (BPI-QoL), and the standard question of Europe Organization for Research and Treatment of Cancer Quality of Life Questionnaire- Bone Metastases 22 (EORTC QLQ-BM22) were respectively recorded before and 1-week, 1-month, 3-month after the treatment. The related adverse events of MRgFUS were observed and recorded in 3 months after the treatment as well. (1)Twenty-three metastatic bone tumor lesions of 23 patients were treated by MRgFUS, the treatment data was as follows: the mean treatment time was (88 ± 33) minutes, the mean sonication number was 13 ± 8. (2) Adverse events included: pain in therapy area 3/23, which spontaneous relieving within one week; numbness in lower limb (1/23), which relieved after physiotherapy. (3) The NRS of before treatment and at 1-week, 1-month, and 3-month after treatment respectively was 6.0 ± 1.5, 3.7 ± 1.7,3.1 ± 2.0, and 2.2 ± 1.0,which significantly decreased after the treatment (P<0.01). (4) The BPI-QoL score of before treatment and at 1-week, 1-month, and 3-month after treatment respectively was 39 ± 16, 27 ± 18, 26 ± 18, and 21 ± 18, which significantly decreased after the treatment (P<0.01). (5) The EORTC QLQ-BM22 score of before treatment and at 1-week, 1-month, and 3-month after treatment respectively was 52 ± 13, 44 ± 12, 42 ± 12, and 39

    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.)

    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.

    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.

    To assess the effectiveness of oral Chinese herbal medicine (CHM) in relieving pain secondary to bone metastases in patients. The searched electronic literature databases included both English and Chinese articles published in the MEDLINE, EMBASE, Wanfang database and China National Knowledge Infrastructure (up to December 2012). The studies included randomized controlled trials (RCTs) comparing CHM plus conventional treatment with conventional treatment alone for patients with pain secondary to bone metastases. The outcomes were the odds ratio (OR) with 95% confidence intervals (CI) for the pain-relief rate and adverse events. A total of 16 RCTs involving 1,008 patients were identified and analyzed. All of the included RCTs were associated with a moderate to high risk of bias. In the metaanalysis, CHM plus conventional treatment increased the pain-relief rate compared with the conventional treatment alone (OR, 2.59; 95% CI 1.95 to 3.45). In subgroup analysis, the pooled OR of the pain-relief rate of CHM plus conventional treatment compared with conventional treatment was 3.11 (95% CI 2.01 to 4.79) for CHM plus bisphosphonates, 2.24 (95% CI 1.33 to 3.78) for CHM plus analgesics, 2.28 (95% CI 1.09 to 4.79) for CHM plus radiotherapy, and 2.22 (95% CI 0.95 to 5.15) for CHM plus analgesics and bisphosphonates. The adverse events included nausea, vomiting, dizziness, fever, and constipation. No serious adverse events were reported in any of the included studies. CHM interventions appear to have beneficial effects on pain secondary to bone metastases in patients. However, published efficacy trials are small in size to draw any firm conclusions.

    Full text: 105 patients with bone metastases from prostate and breast cancer; between 42 and 78 years age (median 61 years) were evaluated. Patients had intense pain that could not be managed with combinations of analgesic and anti tumoral drugs. All patients received 1.2 mCi/kg of Samarium-153 intravenously as treatment for pain due to bony metastases. The isotope obtained from atomic reactor placed in Lima - Peru, was provided by Peruvian Nuclear Energy Institute (IPEN). One week before therapy, all the patients had a bone scan study with Tc99m-MDP that showed the presence of multiple bone metastases with high blastic activity. Haematology and biochemical parameter checked were: Creatinine ( 150,000 mm3), Leukocytes (> 5,000 mm3), Red cells (>3,500,000 mm3). No problems were encountered during intravenous administration of the radioisotope. The side effects after treatment were: Primary effects: 16 cases of nausea, 2 of vomiting, 3 of headache, 28 had increment of pain, 6 had flushing. 50 patients did not have the primary symptoms. Secondary effects: 3 Patients showed drop in leukocyte count between 2nd and 3rd week of therapy. Red cells showed 10-15% decrease between 6th to 8th week. Platelets showed a decrease of about 15% with one peak between 1st and 2nd week post Samarium therapy. Data was analysed using an analogue visual scale of the pain with values from 0 - 10 (0-no pain; 10-maximum pain) and in the same way using the E.C.O.G. scale (Eastern Cooperative Oncology Group) in relationship with the Karnofsky index in order to establish functional recovery for each patient. The decrease of pain was seen between 4th-7th days (average 8 days). A second dose was given after 60 days in 12 patients and a third dose in 3 cases.11 patients died due to different causes between 30 - 60 days post treatment. The analgesic dose came down significantly in 80% of patients. We conclude that palliative therapy of metastatic bone pain in Peru is possible with radionuclides. It

    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. 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. 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. 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 uncomplicated bone metastases.

    We have studied bone scintigrams in 60 patients with gastric cancer. Of these 60 patients, bone metastases were found in 15 patients (25 %). There were no evidence of bone metastases in polypoid lesions, cancers of the antrum, carcinomas in situ, advanced cancers without invasion to serosa, cancer with N 0 or N 1 regional lymph node metastases, highly deferenciated adenocarcinomas and papillary adenocarcinomas. On the contrary, high rates of bone metastases were seen in cancers of the corpus, advanced cancers with invasion to neighbouring structures and tubular adenocarcinomas. Of these 15 patients with bone metastasis, 3 patients showed very similar clinical features and the findings of ''diffuse bone metastases on bone scintigrams.'' Cancer of the antrum showed high rates of liver metastases, while cancers of the corpus showed high rates of bone stastases. Sixty percent of the patients with bone metastases did not have liver metastases and there seemed to be no significant relationship between liver metastases and bone metastases. From these results we suppose that non-portal tract through the vertebral venous plexus instead of portal tract may be the other route of bone metastases from gastric cancer. (author)

    Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC) stage T 4 N 2 M 1b , 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 18 F-FDG PET/CT. The patient received 153 Sm-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

    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

  11. Bone scintiscanning in metastases

    The three fold interest of bone scintiscanning is discussed in relation to 182 cases of bone metastases of various origins. Firstly, this technic facilitates early diagnosis of invasion of the bone by the detection of metastatic lesions which, in 7.7% of cases are still infraradiologic, or even of reflex algodystrophy of the legs, which can be detected only from a scintiscan, long before X-ray plates can show the lumbar metastasis which is responsible. Secondly, the method is able to pick up more metastasic sites in 54.4% of cases than can be detected by X-ray; this is confirmed by investigation of the S/R ratio (ratio of the number of strongly binding sites to the number of sites showing radiologic damage) which is greater than unity for a considerable period. Thirdly, repeated scintiscanography provides a prognosis, because the survival time appears to be fairly closely correlated with the regression, stability or extension of strongly binding sites, although a ''flare phenomenon'' may give the erroneous impression that the metastatic process has deteriorated. Repeated scintiscanography also provides a good way of evaluating the efficacy of medical treatment, particularly in the case of bone metastases of mammary or prostatic origin. Sometimes, the decision for or against prophylactic or palliative orthopedic surgery may be based to a considerable extent on data provided by scintiscan [fr

    The Centers against cancer of Caen, Angers, Montpellier, Strasbourg and 'the Curie Foundation' have confronted their experience in detection of bone metastases by total body scanning. From the investigation by this procedure, of 1,467 patients with cancer, it results: the confrontation between radio and scanning shows a rate of false positive and false negative identical to the literature ones; the countage scanning allows to reduce the number of false positive; scanning allows to direct bone biopsy and to improve efficiency of histological examination [fr

    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.

    The authors have investigated 6 cases of bone metastases from cervical cancer out of a total of 90 cases of metastatic bone tumors that were irradiated for relief of associated pain at the Department of Radiology, Nagasaki University Hospital from April 1977 to March 1987. In 2 of the 6 cases, a rare, delayed recurrence with paraaortic lymph node metastases was seen. An invasion to the proasmajor muscle, iliomajor muscle was demonstrated by Computed Tomography after the initiation of therapy, so that the size of the field was modified. Computed Tomography was found useful to determine the exact field size for radiotherapy of metastatic bone tumor.

    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.

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.

    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

    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

    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....

    Purpose: The NCIC CTG Symptom Control.20 randomized trial (SC.20) confirmed the effectiveness of re-irradiation to painful bone metastases. This companion study correlates urinary markers of osteoclast activity with response to re-irradiation, survival and skeletal related events (SREs). Methods: Pain response was assessed using the International Consensus Endpoints. Urinary markers of bone turnover-pyridinoline (PYD), deoxypyridinoline (DPD), N-telopeptide (NTX), Alpha and Beta cross-laps of C-telopeptide (CTX)-before and 1 month after re-irradiation were correlated to response to re-irradiation and then to both, either or none of the initial and re-irradiation: frequent responders (response to both); eventual responders (response to re-irradiation only); eventual non-responders (response to initial radiation only), and absolute non-responders (no response to both). Results: Significant differences between 40 responders and 69 non-responders to re-irradiation existed for PYD (p = 0.03) and DPD (p = 0.04) at baseline. When patients were categorized as frequent responders (N = 34), eventual responders (6), eventual non-responders (59) and absolute non-responders (10), the mean values of all markers in the absolute non-responders at baseline and the follow-up were about double those for the other three groups with statistically significant difference for DPD (p = 0.03) at baseline. Absolute non-responders had the worst survival. The few occurrences of the SREs did not allow meaningful comparisons among the groups. Conclusion: There were significant differences between responders and non-responders to re-irradiation for PYD and DPD at baseline. The urinary markers in the absolute non-responders were markedly elevated at both baseline and follow-up with a statistically significant difference for DPD at baseline

    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

    Cancer prevalence is estimated at around 2% of the population and on average between 64-80% of patients with solid tumors develop bone metastases, being breast tumors, lung and prostate those who do more frequency. In this paper an estimate of the prevalence of bone pain from metastases, with reference to the data reported in the literature is presented. the different treatment techniques are summarized for pain management with special emphasis on Radionuclidic therapy, analyzing the different factors to consider for the selection of suitable radiopharmaceutical. cost data and cost-benefit of some radiopharmaceuticals for the purpose to take into account during their selection are provided. It is concluded that although the treatment of metastatic bone disease requires multidisciplinary therapies, Radionuclidic therapy is not sufficiently used, particularly by inadequate perception of risks and costs of radiopharmaceuticals, despite the undeniable support of its efficacy and tolerability.

    Complications of bone metastases can seriously influence quality of life of the patients including of their independence in activities of daily living. Bisfosfonates are reducing skeletal morbidity in solid tumors and in multiple myeloma by 30 - 50% (1). They are not only used in active antineoplastic therapy in the prevention of skeletal complications by bone metastases but they are also significantly useful in prevention of the decrease of osseous mass by hormonal manipulation. Preclinical and in part clinical data suppose that there is some role of bisfosfonates in prevention of formation of metastases by early cancer. Denosumab is fully humanized antibody against RANKL (receptor activator of nuclear factor κ-B ligand) which is very important in pathogenesis of bone resorption induced by osteoclasts. In this work we discuss about pathological mechanisms of bone resorption in multiple myeloma and solid tumors, we resume data from randomized clinical trials and we focus on the application of anti resorption therapy in clinical practice.

    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.

    Background. To investigate the utility of stereotactic body radiotherapy (SBRT) in the treatment of painful renal cell carcinoma (RCC) bone metastases, and for a possible dose effect on time to symptom relief. Material and methods. Eighteen patients with 24 painful osseous lesions from metastatic RCC were treated with SBRT. The most common treatment regimens were 24 Gy in 3 fractions and 40 Gy in 5 fractions. The times from treatment to first reported pain relief and time to symptom recurrence were evaluated. Median follow-up was 38 weeks (1-156 weeks). Results. Seventy-eight percent of all patients had pain relief. Patients treated with a BED > 85 Gy achieved faster and more durable pain relief compared to those treated with a BED < 85 Gy. There was decrease in time to pain relief after a change in treatment regimen to 8 Gy x 5 fractions (BED = 86). There was only one patient with grade 1 skin toxicity. No neurological or other toxicity was observed. Conclusions. SBRT can safely and effectively treat painful RCC bony metastases. There appears to be a relationship between radiation dose and time to stable pain relief.

    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.

    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.

    Here we report our experience with bone SPET in the diagnosis of vertebral metastases. This is a retrospective study of technetium-99m methylene diphosphonate (MDP) bone scans in 174 consecutive patients who were referred for the investigation of back pain in our department. MDP planar and SPET images were obtained. Of teh 174 patients, 98 had a known history of malignant tumours. The diagnosis of vertebral metastasis was made on the basis of the patients' clinical histories and the findings with other imaging techniques such as magnetic resonance imaging, computed tomography or follow-up bone scan. We found that the presence of pedicle involvement as seen on SPET was an accurate diagnostic criterion of vertebral metastasis. SPET had a sensitivity of 87%, a specificity of 91%, a positive predictive value of 82%, a negative predictive value of 94% and an accuracy of 90%. On the other hand, planar study had a sensitivity of 74%, a specificity of 81%, a positive predictive value of 64%, a negative predictive value of 88% and an accuracy of 79% in diagnosing vertebral metastasis. Except with regard to the negative predictive value, SPET performed statistically better than planar imaging. Only 9/147 (6.4%) lesions involving the vertebral body alone and 3/49 (6.1%) lesions involving facet joints alone were subsequently found to be metastases. We conclude that bone SPET is an accurate diagnostic test for the detection of vertebral metastases and is superior to planar imaging in this respect. (orig./MG) (orig.)

    This paper deals with the international experience of using sodium orthophosphate labeled with 32 P as a first radiopharmaceutical for the treatment of metastatic bone disease (EOM).

    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.

    Background and purpose: To investigate whether single-fraction radiotherapy is equal to multiple fractions in the treatment of painful metastases. Patients and methods: The study planned to recruit 1000 patients with painful bone metastases from four Norwegian and six Swedish hospitals. Patients were randomized to single-fraction (8 Gyx1) or multiple-fraction (3 Gyx10) radiotherapy. The primary endpoint of the study was pain relief, with fatigue and global quality of life as the secondary endpoints. Results: The data monitoring committee recommended closure of the study after 376 patients had been recruited because interim analyses indicated that, as in two other recently published trials, the treatment groups had similar outcomes. Both groups experienced similar pain relief within the first 4 months, and this was maintained throughout the 28-week follow-up. No differences were found for fatigue and global quality of life. Survival was similar in both groups, with median survival of 8-9 months. Conclusions: Single-fraction 8 Gy and multiple-fraction radiotherapy provide similar pain benefit. These results, confirming those of other studies, indicate that single-fraction 8 Gy should be standard management policy for these patients

    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.

    To objectively compare the response of the palliative radiotherapy in bone metastatic patients which decreases pain and prevents pathologic fractures, we introduced and applied the RTOG pain and narcotic measure system. From Oct in 1991 to July in 1993, thirty-two patients with painful bone metastases, 17 of them were solitary lesions and others were multiple lesions, were treated with mainly 6 MV photon otherwise 15 MV photon. Radiation doses to bone metastatic sites ranged about from 2000 to 4600cGy. Responses of radiation therapy were compared with days of pre-RT, RT finish, 3, 6, 9 months after the start of RT and solitary versus multiple lesions and follow up scores according to the RTOG measure system. Survival analysis was done. Pain and narcotic score of the entire patients were 7.3, 7.8 at the pre-RT period and 2.6, 3.9 at the immediate or 2 weeks after RT, which was 64%, 50% decrement compared with the pre-RT score. Pain scores of 3, 6 and 9 months after the beginning of irradiation were 3.6, 3.7 and 3.3. The best response found in the breast and prostate primaries was 84%, 78% decrement of pain score as compared with pre-RT score (statistically insignificant). Median survival was 5.5 months and mean survival was 5 months. We conclude that the RTOG pain and narcotic measure system in relatively effective scale in the comparison of before and after palliative irradiation to the painful bone metastatic sites but more detailed parameters will be required in the narcotic scoring system. More aggressive but less or similar toxic radiotherapy is needed in the patients having relatively long life expected time

    We have studied bone scintigrams in 60 patients with gastric cancer. Of these 60 patients, bone metastases were found in 15 patients (25 %). There were no evidence of bone metastases in polypoid lesions, cancers of the antrum, carcinomas in situ, advanced cancers without invasion to serosa, cancer with N/sub 0/ or N/sub 1/ regional lymph node metastases, highly differentiated adenocarcinomas and papillary adenocarcinomas. On the contrary, high rates of bone metastases were seen in cancers of the corpus, advanced cancers with invasion to neighbouring structures and tubular adenocarcinomas. Of these 15 patients with bone metastasis, 3 patients showed very similar clinical features and the findings of ''diffuse bone metastases on bone scintigrams.'' Cancer of the antrum showed high rates of liver metastases, while cancers of the corpus showed high rates of bone metastases. Sixty percent of the patients with bone metastases did not have liver metastases and there seemed to be no significant relationship between liver metastases and bone metastases. From these results we suppose that non-portal tract through the vertebral venous plexus instead of portal tract may be the other route of bone metastases from gastric cancer.

  5. Prevention and Treatment of Bone Metastases in Breast Cancer

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

    Bone is the most common metastatic site associated with breast cancer. Using a database of women with breast cancer treated at Guy's Hospital, London 1976-2006 and followed until end 2010, we determined incidence of and survival after bone metastases. We calculated cumulative incidence of bone metastases considering death without prior bone metastases as a competing risk. Risk of bone metastases was modelled through Cox-regression. Survival after bone metastases diagnosis was calculated using Kaplan-Meier methodology. Of the 7064 women, 589 (22%) developed bone metastases during 8.4 years (mean). Incidence of bone metastases was significantly higher in younger women, tumour size >5 cm, higher tumour grade, lobular carcinoma and ≥ four positive nodes, but was not affected by hormone receptor status. Median survival after bone metastases diagnosis was 2.3 years in women with bone-only metastases compared with early, and proportionately fewer patients in this group. Incidence of bone metastases has decreased but bone metastases remain a highly relevant clinical problem due to the large number of patients being diagnosed with breast cancer.

    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

    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.

    Approximately 80% of patients with prostate cancer will develop bone metastases, which often lead to bone pain and skeletal-related events. Sr-89 is an established alternative for the palliation of bone pain in prostate cancer. We aimed to assess the effect of Sr-89 radionuclide therapy on quality of life (QOL) in prostate cancer patients with painful bone metastases. Thirteen patients received a single intravenous injection of Sr-89 at a dose of 2.0 MBq/kg. All patients underwent QOL evaluation prior to Sr-89 treatment and 1, 2, and 3 months afterward using the Japanese version of the European Organisation for Research and Treatment of Cancer developed a Quality of Life questionnaire for Patients with Bone Metastases 22(EORTC QLQ-BM22), EORTC Quality of Life Group core questionnaire (EORTC QLQ-C30), a visual analog scale (VAS), and face scale. We also evaluated prostate-specific antigen (PSA) and serum alkaline phosphatase (ALP) response and toxicity of the Sr-89 therapy. The pain characteristics subscale of the EORTC QLQ-BM22 was significantly reduced from 1 month onward compared with the baseline. The functional interference and psychosocial aspects subscales were significantly higher than baseline from 2 months onward. At 2 months, VAS indicated a significant reduction in pain as compared to the baseline. Sr-89 therapy caused a nonsignificant reduction in PSA and ALP levels. No patients had leukocyte toxicity, and one patient had grade 3 platelet toxicity. Sr-89 radionuclide therapy can provide not only reduced pain characteristics but also better psychosocial aspects and functional interference in patients with painful bone metastases of prostate cancer.

    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

    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

    Many patients with cancer develop bone metastases with pain as an important symptom impacting on quality of life. Conventional radiotherapy is the standard local treatment, effective in a small majority of patients (61%). This means that a large portion of patients does not respond to radiotherapy.

    Purpose: External beam radiotherapy (RT) is commonly indicated for the palliation of symptomatic bone metastases, but there is evidence of underutilization of this treatment modality in palliative care for cancer populations. This study was conducted to investigate factors that influenced the use of palliative RT services at a regional comprehensive cancer center. Methods and Materials: A cohort of patients with radiographically confirmed bone metastases and first-time users of palliative RT between 2003 and 2005 was retrospectively reviewed from the time of initial diagnosis of bone metastases to death or last follow-up. Type of radiation treatment service provider used (rapid access or routine access) and patient-, tumor-, and treatment-related factors were analyzed for their influences on the number of treatment courses given over the duration of disease. Results: A total of 887 patients received 1,354 courses of palliative RT for bone metastases at a median interval of 4.0 months between courses. Thirty-three percent of patients required more than one RT course. Increased age and travel distance reduced the likelihood and number of treatment courses, while service through a rapid access clinic was independently associated with an increase in subsequent use of palliative RT. Conclusions: A rapid access service model for palliative RT facilitated access to RT. Travel distance and other factors remained substantial barriers to use of palliative RT services. The pattern of practice suggests an unmet need for symptom control in patients with bone metastases.

    Background and purpose: Despite numerous randomized trials investigating radiotherapy (RT) fractionation schedules for painful bone metastases, there are very few data on RT for bone metastases causing pain with a neuropathic component. The Trans-Tasman Radiation Oncology Group undertook a randomized trial comparing the efficacy of a single 8 Gy (8/1) with 20 Gy in 5 fractions (20/5) for this type of pain. Materials and methods: Eligible patients had radiological evidence of bone metastases from a known malignancy with no change in systemic therapy within 6 weeks before or anticipated within 4 weeks after RT, no other metastases along the distribution of the neuropathic pain and no clinical or radiological evidence of cord/cauda equina compression. All patients gave written informed consent. Primary endpoints were pain response within 2 months of commencement of RT and time to treatment failure (TTF). The hypothesis was that 8/1 is at least as effective as 20/5 and the planned sample size was 270 patients. Results: Between February 1996 and December 2002, 272 patients were randomized (8/1:20/5=137:135) from 15 centres (Australia 11, New Zealand 3, UK 1). The commonest primary cancers were lung (31%), prostate (29%) and breast (8%); index sites were spine (89%), rib (9%), other (2%); 72% of patients were males and the median age was 67 (range 29-89). The median overall survival (95% CI) for all randomized patients was 4.8 mo (4.2-5.7 mo). The intention-to-treat overall response rates (95% CI) for 8/1 vs 20/5 were 53% (45-62%) vs 61% (53-70%), P=0.18. Corresponding figures for complete response were 26% (18-34%) vs 27% (19-35%), P=0.89. The estimated median TTFs (95% CI) were 2.4 mo (2.0-3.3 mo) vs 3.7 mo (3.1-5.9 mo) respectively. The hazard ratio (95% CI) for the comparison of TTF curves was 1.35 (0.99-1.85), log-rank P=0.056. There were no statistically significant differences in the rates of re-treatment, cord compression or pathological fracture by arm

    Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases.

    The objective of this study was to determine which of the following three methods is the most effective for the treatment of bone metastases from hepatocellular carcinoma (HCC): transcatheter arterial embolization (TAE); combination of TAE and external radiotherapy; or external radiotherapy alone. Thirty-nine metastatic bone lesions from HCC in 33 patients were retrospectively reviewed. Each lesion underwent either TAE alone (group A, n=11), TAE followed by radiotherapy (group B, n=17), or radiotherapy alone (group C, n=11). They were evaluated on the following subjects: pain relief; improvement of daily activities; and complications. Each treatment was effective for pain relief (89-94%) and improvement of daily activities (73-82%). The mean time interval from the beginning of each treatment to the onset of initial pain relief was 4.7 days in group A, 4.8 days in group B, and 15 days in group C. Recurrence of the pain after the initial pain relief was noted in 75% in group A, 20% in group B, and 88% in group C. Pyrexia and local pain commonly occurred after TAE. In conclusion, TAE is effective in relieving pain immediately and in improving the patients' daily activities. The combination of TAE and radiotherapy is recommended for permanent pain relief.

    Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-yea...

    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.

    Objective: To evaluate the efficacy of 89 Sr in treatment of multiple bone metastases of breast and prostate cancer patients. Methods: Seventy multiple bone metastases patients (30 females with breast cancer and 40 males with prostate cancer) were treated with 89 Sr. The clinical effectiveness was assessed by Karnofsky performance score and whole body bone scanning data. Results: The total pain relief rate was 79% in bone metastases of breast cancer and 85% in bone metastases of prostate cancer, respectively. There was no significant differences between the two groups (χ 2 =0.78, P>0.05). The Karnofsky score was significantly improved in both groups (t=2.46, P 89 Sr treatment was good, and the quality of life was improved in patients with multiple bone metastases breast or prostate cancer.

    The incidence of bone metastases(BMs)from hepatocellular carcinoma(HCC)is relatively low compared to those of other cancers,but it has increased recently,especially in Asian countries.Typically,BMs from HCC appear radiologically as osteolytic,destructive,and expansive components with large,bulky soft-tissue masses.These soft-tissue masses are unique to bone metastases from HCC and often replace the normal bone matrix and exhibit expansive growth.They often compress the peripheral nerves,spinal cord,or cranial nerves,causing not only bone pain but also neuropathic pain and neurological symptoms.In patients with spinal BMs,the consequent metastatic spinal cord compression(MSCC)causes paralysis.Skull base metastases(SBMs)with cranial nerve involvement can cause neurological symptoms.Therefore,patients with bony lesions often suffer from pain or neurological symptoms that have a severe,adverse effect on the quality of life.External-beam radiotherapy(EBRT)can effectively relieve bone pain and neurological symptoms caused by BMs.However,EBRT is not yet widely used for the palliative management of BMs from HCC because of the limited number of relevant studies.Furthermore,the optimal dosing schedule remains unclear,despite clinical evidence to support single-fraction ra-diation schedules for primary cancers.In this review,we outline data describing palliative EBRT for BMs from HCC in the context of(1)bone pain;(2)MSCC;and(3)SBMs.

    During routine investigations, we are surprised to find that therapy for bone metastases is sometimes delayed for a considerable period of time. To determine the extent of this delay and its causes, we reviewed the medical records of symptomatic patients seen at our hospital who had been recently diagnosed as having bone metastases for the last four years. The treatment delay was defined as the interval between presentation with symptoms and definitive treatment for bone metastases. The diagnostic delay was defined as the interval between presentation with symptoms and diagnosis of bone metastases. The results of diagnostic radiological examinations were also reviewed for errors. The study population included 76 males and 34 females with a median age of 66 years. Most bone metastases were diagnosed radiologically. Over 75% of patients were treated with radiotherapy. The treatment delay ranged from 2 to 307 days, with a mean of 53.3 days. In 490 radiological studies reviewed, we identified 166 (33.9%) errors concerning 62 (56.4%) patients. The diagnostic delay was significantly longer for patients with radiological errors than for patients without radiological errors (P < 0.001), and much of it was due to radiological errors. In conclusion, the treatment delay in patients with symptomatic bone metastases was much longer than expected, and much of it was caused by radiological errors. Considerable efforts should therefore be made to more carefully examine the radiological studies in order to ensure prompt treatment of bone metastases. (author)

    2011-01-01

    Purpose: To present guidance for patients and physicians regarding the use of radiotherapy in the treatment of bone metastases according to current published evidence and complemented by expert opinion. Methods and Materials: A systematic search of the National Library of Medicine's PubMed database between 1998 and 2009 yielded 4,287 candidate original research articles potentially applicable to radiotherapy for bone metastases. A Task Force composed of all authors synthesized the published evidence and reached a consensus regarding the recommendations contained herein. Results: The Task Force concluded that external beam radiotherapy continues to be the mainstay for the treatment of pain and/or prevention of the morbidity caused by bone metastases. Various fractionation schedules can provide significant palliation of symptoms and/or prevent the morbidity of bone metastases. The evidence for the safety and efficacy of repeat treatment to previously irradiated areas of peripheral bone metastases for pain was derived from both prospective studies and retrospective data, and it can be safe and effective. The use of stereotactic body radiotherapy holds theoretical promise in the treatment of new or recurrent spine lesions, although the Task Force recommended that its use be limited to highly selected patients and preferably within a prospective trial. Surgical decompression and postoperative radiotherapy is recommended for spinal cord compression or spinal instability in highly selected patients with sufficient performance status and life expectancy. The use of bisphosphonates, radionuclides, vertebroplasty, and kyphoplasty for the treatment or prevention of cancer-related symptoms does not obviate the need for external beam radiotherapy in appropriate patients. Conclusions: Radiotherapy is a successful and time efficient method by which to palliate pain and/or prevent the morbidity of bone metastases. This Guideline reviews the available data to define its proper use

    Local bone pain and osseous scintigraphic findings were evaluated in patients with cancer of the lung, breast or prostate. (1) In 77-92% out of the patients with local pain, metastatic bone lesions were detected. (2) The sacrum and scapulae were the frequent sites of pain as estimated from the metastatic bone lesions. On the other hand, the incidence of pain was low in the ribs, cervical vertebrae, skull and femurs. (3) When calculated by the weight of red bone marrow, the most likely sites for bone metastases consisted of the scapulae, clavicles, sternum, humeri, ribs and cervical vertebrae, somewhat different from previous reports. Those bones involved were all proximate to the heart. (4) Extensive bone metastases were already detected in more than 50% of patients who complain of pain in the metastatic bone lesion. On the other hand, extensive bone metastases occurred in less than 6% of patients who didn't complain of pain. (5) The appearance of pain in the metastatic bone lesion was earlier in only 3% and was later in 71% than the detection of abnormal radioisotope accumulation on scintigram. (6) Majority of the patients with pain in the metastatic bone lesion showed a high degree of abnormal radioisotope accumulation which measured more than 5 cm in diameter on scintigram. On the other hand, the abnormal radioisotope accumulation in most of patients without pain was mild and mostly measured less than 5 cm in diameter. (7) The positive rate of bone metastasis amounted to 29% by plain X-ray and 41% by local bone pain as compaired to positive bone scintigram. (author)

    Full Text Available Draupadi B TalrejaDepartment of Medicine, David Geffen School of Medicine at UCLA and Northridge Hospital Medical Center, Northridge, CA, USAAbstract: Patients with bone metastases are at risk of skeletal-related events such as pathologic fractures, spinal cord compression, the need for orthopedic surgery to bone, and palliative radiotherapy for severe bone pain. Antiresorptive therapies have demonstrated efficacy for reducing the risk of skeletal-related events and ameliorating bone pain. Despite the well documented clinical benefits of antiresorptive therapies, patient benefits can be limited or compromised by nonadherence with scheduled therapy. Potential reasons for poor compliance include lack of understanding of how antiresorptive therapies work, neglecting the importance of bone health in maintaining quality of life, and being unaware of the potentially debilitating effects of skeletal-related events caused by bone metastases. Indeed, patients may stop therapy after bone pain subsides or discontinue due to generally mild and usually manageable adverse events, leaving them at an increased risk of developing skeletal-related events. In addition, the cost of antiresorptive therapy can be a concern for many patients with cancer. Medical care for patients with cancer requires a coordinated effort between primary care physicians and oncologists. Patients' medical care teams can be leveraged to help educate them about the importance of adherence to antiresorptive therapy when cancer has metastasized to bone. Because primary care physicians generally have more contact with their patients than oncologists, they are in a unique position to understand patient perceptions and habits that may lead to noncompliance and to help educate patients about the benefits and risks of various antiresorptive therapies in the advanced cancer setting. Therefore, primary care physicians need to be aware of various mechanistic and clinical considerations regarding

    Purpose: To determine the proportion of patients undergoing palliative radiotherapy (RT) for bone pain who would like to participate in the decision-making process, and to determine their choice of palliative RT regimen (2000 cGy in five fractions vs. 800 cGy in one fraction) for painful bone metastases. Methods and Materials: Eligible patients were approached and all patients agreeing to participate provided written informed consent. Patients' decisional preferences were studied using a five-statement preference instrument. A decision board was used to help patients decide their preferred palliative RT regimen. Factors influencing patients' choices were studied using a visual analog scale. Results: A total of 101 patients were enrolled in the study (55 women and 46 men). The preferences for decision-making were as follows: 30 active, 47 collaborative, and 24 passive. Most (55 [76%] of 72) patients favored one fraction of palliative RT (95% confidence interval, 65-86%). Patients were more likely to select the 800 cGy in one fraction because of the convenience of the treatment plan (odds ratio, 1.024; 95% confidence interval, 1.004-1044) but were less likely to choose it because of the chance of bone fracture (odds ratio, 0.973; 95% confidence interval, 0.947-1.000) compared with 2000 cGy in five fractions. Conclusion: Most participating patients preferred to decide either by themselves or with the radiation oncologists which treatment option they preferred. An 800-cGy-in-one-fraction regimen was favored, independent of the treated site. The convenience of the treatment plan and the likelihood of bone fracture were the most important factors influencing patients' choice

    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)

    Purpose: In a prospective randomized trial we examined whether radiotherapy of painful bone metastases can be shortened using larger single doses without impairing effectivity. Methods and Materials: One hundred patients with painful bone metastases having no prior surgical intervention or treatment with x-ray therapy and had a median follow-up of 12 months were analyzed. The primary tumor was located in the breast in 43%, in the lung in 24%, and in the prostate in 14%. The most frequent sites of metastases were the pelvis (31%), the vertebral column (30%), and the ribs (20%). Further percentages of sites were: lower extremity 11%, upper extremity 6%, and skull 2%. Fifty-one patients received a short course radiotherapy with a total dose of 20 Gy in 1 week (daily dose 4 Gy), and 49 patients received 30 Gy in 3 weeks (daily dose 2 Gy). Results: There were no significant differences in frequency, duration of pain relief, improvement of mobility, recalcification, frequency of pathologic fractures nor survival. There was a light trend favoring 30 Gy in frequency of pain relief and recalcification. Survival was mostly influenced by primary tumor site, Karnofsky performance status, and possibly by the response to radiotherapy (pain relief). Conclusions: Because of the very short life expectancy of patients with metastatic bone disease, we now use 20 Gy in 1 week as our standard to reduce hospital stay

    Radioimmune imaging of bone marrow was performed by technetium-99m- (99mTc) labeled antigranulocyte monoclonal antibody BW 250/183 (AGMoAb) scans in 32 patients with suspected bone metastases from primary breast cancer. AGMoAb scans showed bone marrow defects in 25/32 (78%) patients; bone invasion was subsequently confirmed in 23 (72%) patients. Conventional bone scans performed within the same week detected bone metastases in 17/32 (53%) patients (p less than 0.001). AGMoAb scans detected more sites indicating metastatic disease than bone scans in 12 of these 17 patients (71%). All patients with bone metastases in the axial skeleton had bone marrow defects at least at the sites of bone metastases. Of 15 patients with normal, or indicative of, benign disease bone scans, 8 patients (53%) presented with bone marrow defects in the AGMoAb scans. Bone invasion was confirmed in six of them. AGMoAb bone marrow scans provide a method for the early detection of bone metastatic invasion in patients with breast cancer and suspected bone metastases

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

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

    Full text: Introduction: PET-CT is an established technique in staging cancer patients and monitoring the therapeutic response. In the literature it has been pointed out the different uptake in osteosclerotic and osteolytic metastases due to different metabolic activity. Objective: The aim of this study is to share authors initial experience in 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) evaluation of bone metastases secondary to breast cancer with different morphological appearance and to compare the diagnostic accuracy of CT and PET alone and in combination. Patients and methods: Fifty-nine (59) patients with bone lesions secondary to breast carcinoma are included in the retrospective study. The imaging protocol included a low-dose 16-raw detector CT scan with consequent PET scanning after the administration of 5 MBq/kg 18F-FDG activity. Bone metastases were characterized morphologically as being osteolytic, osteoblastic or mixed and metabolically as active, nonactive. Standard uptake value (SUV) of the most active metastatic lesion in each patient is measured. Results: Most patients had more than one type of bone metastases. 23 patients (38.98%) had osteolytic bone metastases, 32 (54.23%) had mixed, 14 (23.72%) had osteoblastic and 8 (13.55%) patients had metabolically active bone metastases without any morphological evidence. All of the osteolytic and all of the mixed bone lesions were metabolically active (100%). Amongst the osteoblastic bone metastases metabolic activity was seen in 11 (78.57%) patients and the rest 3 (21.42%) of them had only morphological evidence of bone lesions due to good therapeutic response. SUV varies from 3.2 to 18.5 (normal uptake threshold - 2.5). The aggressiveness of bone lesions is related to high metabolic activity and the lack of the latter is usually a sign of good therapeutic response. Metabolic activity without morphological changes is a feature of early bone marrow affection and

    The single 89 Sr therapy has been used for pain relief in patients with multiple bony metastases and it is known to be very effective without serious complications except mild bone marrow suppression. But usually repeated therapy is needed because it is not a completely curative therapy. This study was performed to evaluate the effects of repeated 89 Sr therapy on therapeutic outcome compared to first therapy. This study was performed retrospectively with fifteen breast cancer patients treated more than twice with 89 SrCl 2 against multiple bony metastases. There were total 42 cases-there were eight, four, two and one patients treated twice, three times, four times and six times respectively. The time interval between therapy was 179.1±107.5 (90-550) days. We scored zero to five about performance, analgesics, subjective pain, sleep pattern respectively and summed as the pain score (0-20). Before therapy and one month and three months after therapy the pain score was evaluated and blood leukocyte and platelet was estimated. Bone scan was performed before therapy and one, three and six months after therapy. The pain score was 6.5±2.4 (2-10) before first therapy. Among 42 cases the pain score was improved in 22 cases (52.4%), not changed in 8 cases (19.0%) and aggravated in 12 cases (28.6%). The pain score was not affected by therapy number. Bone scan showed various changes without statistical correlation with pain score. One month after therapy blood leukocyte and platelet was decreased more than 20% than before therapy in six cases (28.6%) and seven cases (16.7%) among 21 cases, respectively. The leukocyte and platelet was not more decreased as increased therapy number. The repeated 89 Sr therapy is not so different from the first therapy in effects and bone marrow suppression. Bone scan finding was independent to the pain score

    Purpose: The purpose of this course is to discuss the current radiotherapeutic strategies in the treatment of bone metastases. Radiation therapy continues to play a central role in the relief of symptoms associated with bone metastases. The introduction of large field or hemibody and systemic or isotopic radiation techniques has expanded the role of radiation therapy to include evaluation of the impact of radiation on occult and overt yet asymptomatic disease. This course will review some of the basic mechanisms involved in the genesis of bone pain. A comparative analysis of the clinical trials of local field irradiation on bone metastases including dose and fractionation schedules, response rates, duration and evaluation of response will be discussed. The role of large field hemibody and systemic irradiation (e.g. isotopestrontium) in the treatment of metastatic disease will be presented. The topics include the response rates and duration of response of symptomatic metastases, the effect of each technique on the delay in progression of overt symptomatic disease as well as a delay in the appearance of new disease and the morbidity associated with each treatment modality. The design of several current trials will be presented as well as concepts for an expanding role of large field and systemic radiation techniques will be presented. The current managed care climate has brought to the forefront some basic issues regarding the economic impact of palliative radiotherapy. Therefore, this course will present an analysis of radiotherapeutic and non-radiotherapeutic management of pain associated with bone metastases as well as discussion of the basic techniques of economic analyses. Techniques of cost-minimization, cost-utility, cost-benefit, and cost-effective analyses and the appropriateness of each type of analyses will be presented. A discussion of which costs and benefits to include in the analyses will also be presented

    Patients with bone metastases are at risk of skeletal-related events such as pathologic fractures, spinal cord compression, the need for orthopedic surgery to bone, and palliative radiotherapy for severe bone pain. Antiresorptive therapies have demonstrated efficacy for reducing the risk of skeletal-related events and ameliorating bone pain. Despite the well documented clinical benefits of antiresorptive therapies, patient benefits can be limited or compromised by nonadherence with scheduled therapy. Potential reasons for poor compliance include lack of understanding of how antiresorptive therapies work, neglecting the importance of bone health in maintaining quality of life, and being unaware of the potentially debilitating effects of skeletal-related events caused by bone metastases. Indeed, patients may stop therapy after bone pain subsides or discontinue due to generally mild and usually manageable adverse events, leaving them at an increased risk of developing skeletal-related events. In addition, the cost of antiresorptive therapy can be a concern for many patients with cancer. Medical care for patients with cancer requires a coordinated effort between primary care physicians and oncologists. Patients’ medical care teams can be leveraged to help educate them about the importance of adherence to antiresorptive therapy when cancer has metastasized to bone. Because primary care physicians generally have more contact with their patients than oncologists, they are in a unique position to understand patient perceptions and habits that may lead to noncompliance and to help educate patients about the benefits and risks of various antiresorptive therapies in the advanced cancer setting. Therefore, primary care physicians need to be aware of various mechanistic and clinical considerations regarding antiresorptive treatment options

    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 metastases are extremely rare in patients with classical Wilms' tumor (WT). We describe the clinical and radiologic features, treatment and outcome of three patients with WT (one with favorable histology and two with anaplasia) in whom bone metastases were detected at diagnosis or relapse. Bone metastases were documented by skeletal radiographs, computed tomography and/or bone scintigraphy. The patient with favourable histology WT had no evidence of pulmonary metastases and is now free of disease following aggressive chemotherapy and radiotherapy. (orig.)

    Objective: Bone metabolic markers (BMM) are biochemical substances that reflect bone resorption or formation. Some of them have been found to be useful in the diagnosis and management of bone metastases. The aim of this study was to investigate the usefulness of two bone resorption markers: bone-specific alkaline phosphatase (B-ALP) and N-terminal procollagen propeptides of type I collagen (PINP), as well as two bone formation markers: cross linked N and C terminal telepeptides of type I collagen (NTX and CTX) in the detection of bone metastasis in patients with differentiated thyroid cancer (DTC). Methods: There were sixty-three DTC patients in this study, 33 cases with clinically confirmed bone metastases and 30 cases with no bone metastases. The extents of bone metastases (or extents of the disease, EOD) were classified into four grades (0, I, II and III) according to the clinical and imaging findings including 99 Tc m -MDP, 131 I whole body scans and others. Serum BMM levels were measured by chemiluminescence immunoassay for B-ALP, radioimmunoassay for PINP, ELISA for NTX and electrochemiluminescence immunoassay for CTX. Nonparametric Mann-Whitney U test, grade correlation analysis and receiver operator characteristic (ROC) curve were applied to analyze the correlation between BMM and DTC patients with bone metastases. Results: The serum levels of B-ALP, NTX and CTX were significantly higher in DTC patients with bone metastases than those in patients with no bone metastases (all P 0.05). The serum levels of all markers were correlated with EOD grades (r s =0.371-0.558, all P<0.01). B-ALP level was found to have significant difference between EOD 0 to I (P=0.012). The diagnostic sensitivity and specificity of B-ALP for detecting DTC with bone metastases were 71.1% and 76.7% respectively by ROC curve analysis, which were higher than those of the other three markers. Conclusions: Serum BMM levels of B-ALP, NTX and CTX were useful for the evaluation of DTC with

    Impending spinal cord compression and vertebral fractures are considered contraindications for radionuclide bone pain palliation therapy. However, most of the patients with widespread bone metastases already have weakened vertebral segments that may be broken. Therefore, local field external-beam radiotherapy or percutaneous vertebroplasty (VP) should be considered to improve the patient's quality of life and to institute subsequent appropriate treatment, including radionuclide therapy for bone pain palliation. The objective of this study was to develop a strategy for an effective treatment of bone metastases in patients with widespread bone metastases and intolerable pain, associated with impending cord compression or vertebral fractures. Eleven patients (5 females and 6 males, aged 32-62 years; mean age 53.8 ± 2.7 years) with multiple skeletal metastases from carcinomas of prostate (n = 3), breast (n = 3) and lung (n = 5) were studied. Their mean pain score measured on a visual analogue scale of 10 was found to be 8.64 ± 0.15 (range 8-9) and the mean number of levels with impending cord compression or vertebral fracture was 2.64 ± 0.34 (range 1–4). All patients underwent vertebroplasty and after 3–7 days received Sm-153 ethylene diamine tetra methylene phosphonic acid (EDTMP) therapy. Sm-153 EDTMP was administered according to the recommended standard bone palliation dose of 37 MBq/kg body weight. Whole body (WB) bone scan, computed tomography and magnetic resonance imaging (MRI) were performed before and after treatment in all patients. Pain relief due to stabilization of vertebrae after VP occurred within the first 12 hours (mean 4.8 ± 1.2 hours; range 0.5–12 hours), and the mean pain score was reduced to 4.36 ± 0.39 (range 2–6). Subsequent to Sm-153 EDTMP treatment, further pain relief occurred after 3.91 ± 0.39 days (range 2-6 days) and the pain score decreased to 0.55 ± 0.21 (range 0–2). The responses to treatment were found to be

    Two-thirds of patients with metastatic cancer suffer from pain. Pain originating from skeletal metastases is the most common form of cancer-related pain. Bone pain, often exacerbated by pressure or movement, limits the patient's autonomy and social life. Pain palliation with bone-seeking radiopharmaceuticals has proven to be an effective treatment modality in patients with metastatic bone pain. These bone-seeking radiopharmaceuticals are extremely powerful in treating scattered painful bone metastases, for which external beam radiotherapy is impossible because of the large field of irradiation. 186 Re-hydroxyethylidene diphosphonate (HEDP) is a potentially useful radiopharmaceutical for this purpose, having numerous advantageous characteristics. Bone marrow toxicity is limited and reversible, which makes repetitive treatment safe. Studies have shown encouraging clinical results of palliative therapy using 186 Re-HEDP, with an overall response rate of ca. 70% in painful bone metastases. It is effective for fast palliation of painful bone metastases from various tumours and the effect tends to last longer if patients are treated early in the course of their disease. 186 Re-HEDP is at least as effective in breast cancer patients with painful bone metastases as in patients with metastatic prostate cancer. It is to be preferred to radiopharmaceuticals with a long physical half-life in this group of patients, who tend to have more extensive haematological toxicity since they have frequently been pretreated with bone marrow suppressive chemotherapy. This systemic form of radionuclide therapy is simple to administer and complements other treatment options. It has been associated with marked pain reduction, improved mobility in many patients, reduced dependence on analgesics, and improved performance status and quality of life. (orig.)

    Molecular drivers underlying bone metastases in human cancer are not well understood, in part due to constraints in bone tissue sampling. Here, RNA sequencing was performed of circulating tumor cells (CTC) isolated from blood samples of women with metastatic estrogen receptor (ER) + breast cancer, comparing cases with progression in bone versus visceral organs. Among the activated cellular pathways in CTCs from bone-predominant breast cancer is androgen receptor (AR) signaling. AR gene expression is evident, as is its constitutively active splice variant AR-v7. AR expression within CTCs is correlated with the duration of treatment with aromatase inhibitors, suggesting that it contributes to acquired resistance to endocrine therapy. In an established breast cancer xenograft model, a bone-tropic derivative displays increased AR expression, whose genetic or pharmacologic suppression reduces metastases to bone but not to lungs. Together, these observations identify AR signaling in CTCs from women with bone-predominant ER + breast cancer, and provide a rationale for testing androgen inhibitors in this subset of patients. Implications: This study highlights a role for the AR in breast cancer bone metastasis, and suggests that therapeutic targeting of the AR may benefit patients with metastatic breast cancer.

    Patients with bone metastases in the extremities sometimes require surgical intervention to prevent deterioration of quality of life due to a pathological fracture. The use of localized radiotherapy combined with surgical reinforcement has been a gold standard for the treatment of bone metastases. However, radiotherapy sometimes induces soft tissue damage, including muscle induration and joint contracture. Moreover, cancer cells are not always radiosensitive. Hyperthermia has been studied since the 1940s using an experimental animal model to treat various types of advanced cancer, and studies have now reached the stage of clinical application, especially in conjunction with radiotherapy or chemotherapy. Nevertheless, bone metastases have several special properties which discourage oncologists from developing hyperthermic therapeutic strategies. First, the bone is located deep in the body, and has low thermal conductivity due to the thickness of cortical bone and the highly vascularized medulla. To address these issues, we developed new hyperthermic strategies which generate heat using magnetic materials under an alternating electromagnetic field, and started clinical application of this treatment modality. The purpose of this review is to summarize the latest studies on hyperthermic treatment in the field of musculoskeletal tumors, and to introduce the treatment strategy employing our novel hyperthermia approach.

    To determine whether the calcium-dependent cell adhesion molecule E-cadherin is expressed in metastatic deposits of prostate cancer in bone. Ten bone biopsies containing metastatic deposits of untreated prostatic cancer were obtained and immunohistochemically stained for E-cadherin with the monoclonal antibody HECD-1, using the streptavidin-biotin complex technique. Benign prostatic tissue was used as the control. Of the 10 specimens, nine showed positive expression of E-cadherin, graded as strong in four. E-cadherin expression was strongest in well-differentiated metastases and decreased with increasing tumour grade. In some specimens there were mixed patterns of expression. E-cadherin is strongly expressed in prostatic bone metastases and the degree of expression appears to reflect local tumour grade. This suggests that loss of E-cadherin expression may not be critically linked to metastatic potential.

    To evaluate the extent of pain response and objective response to palliative radiotherapy (RT) for bone metastases from hepatocellular carcinoma according to RT dose. From January 2007 to June 2010, palliative RT was conducted for 103 patients (223 sites) with bone metastases from hepatocellular carcinoma. Treatment sites were divided into the high RT dose and low RT dose groups by biologically effective dose (BED) of 39 Gy10. Pain responses were evaluated using the numeric rating scale. Pain scores before and after RT were compared and categorized into 'Decreased', 'No change' and 'increased'. Radiological objective responses were categorized into complete response, partial response, stable disease and progression using modified RECIST (Response Evaluation Criteria In Solid Tumors) criteria; the factors predicting patients' survival were analyzed. The median follow-up period was 6 months (range, 0 to 46 months), and the radiologic responses existed in 67 RT sites (66.3%) and 44 sites (89.8%) in the high and low RT dose group, respectively. A dose-response relationship was found in relation to RT dose (p=0.02). Pain responses were 75% and 65% in the high and low RT dose groups, respectively. However, no statistical difference in pain response was found between the two groups (p=0.24). There were no differences in the toxicity profiles between the high and low RT dose groups. Median survival from the time of bone metastases diagnosis was 11 months (range, 0 to 46 months). The Child-Pugh classification at the time of palliative RT was the only significant predictive factor for patient survival after RT. Median survival time was 14 months under Child-Pugh A and 2 months under Child-Pugh B and C. The rate of radiologic objective response was higher in the high RT dose group. Palliative RT with a high dose would provide an improvement in patient quality of life through enhanced tumor response, especially in patients with proper liver function.

    The presence of bone metastases has excluded participation of cancer patients in exercise interventions and is a relative contraindication to supervised exercise in the community setting because of concerns of fragility fracture. We examined the efficacy and safety of a modular multimodal exercise program in prostate cancer patients with bone metastases. Between 2012 and 2015, 57 prostate cancer patients (70.0 ± 8.4 yr; body mass index, 28.7 ± 4.0 kg·m) with bone metastases (pelvis, 75.4%; femur, 40.4%; rib/thoracic spine, 66.7%; lumbar spine, 43.9%; humerus, 24.6%; other sites, 70.2%) were randomized to multimodal supervised aerobic, resistance, and flexibility exercises undertaken thrice weekly (EX; n = 28) or usual care (CON; n = 29) for 3 months. Physical function subscale of the Medical Outcomes Study Short-Form 36 was the primary end point as an indicator of patient-rated physical functioning. Secondary end points included objective measures of physical function, lower body muscle strength, body composition, and fatigue. Safety was assessed by recording the incidence and severity of any adverse events, skeletal complications, and bone pain throughout the intervention. There was a significant difference between groups for self-reported physical functioning (3.2 points; 95% confidence interval, 0.4-6.0 points; P = 0.028) and lower body muscle strength (6.6 kg; 95% confidence interval, 0.6-12.7; P = 0.033) at 3 months favoring EX. However, there was no difference between groups for lean mass (P = 0.584), fat mass (P = 0.598), or fatigue (P = 0.964). There were no exercise-related adverse events or skeletal fractures and no differences in bone pain between EX and CON (P = 0.507). Multimodal modular exercise in prostate cancer patients with bone metastases led to self-reported improvements in physical function and objectively measured lower body muscle strength with no skeletal complications or increased bone pain.

    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

    Full text of publication follows. Introduction: the management of bone pain includes analgesia, radiation, hormones, radiofrequency (RF) ablation, chemotherapy, and surgery. Bone pain palliation therapy with radiopharmaceuticals is a cost-effective systemic therapy to relieve pain from skeletal metastases with a consequent decrease in morbidity and an improvement in quality of life. The aim of our study is to evaluate the effect of myelotoxicity of samarium lexidronam (Sm 153 ) in patients with painful bony metastasis. Methods: we reviewed 116 patients aged from 14 to 87 years old, 91 males (78%) and 25 females (22%), having received 1 to 4 treatments of Sm 153 (37 MBq/kg) for painful bony metastases from different primitive tumors: 67 cases of prostate cancer (57.7%), 22 cases of breast cancer (18.9%), 10 cases of pulmonary cancer (8.6%) and others in 14.6% of cases. Clinical follow-up was available for 159 treatments, consisting on blood count each week over at least two months, in order to evaluate myelotoxicity according to WHO classification. Results: no patients had grade 4 toxicity after its cures. A grade 2-3 myelotoxicity was observed after 52 treatments (34%) during the second week and after 50 treatments (32.6%) during the fourth week with a satisfactory reversibility. At 10 weeks of treatment, myelotoxicity was reclassified from 0 to 2 for 139 cures (90,8%). Moreover, we found that prior treatment with radiotherapy or chemotherapy did not affect the rates of myelotoxicity. Conclusion: multiple treatments with samarium Sm 153 lexidronam had no significant effect on myelotoxicity. Patients with bone predominant metastatic disease may survive for extended periods of time and may safely be treated with multiple modalities of therapy. (authors)

Methods and Materials: Thirty-three patients receiving computed tomography (CT)-simulated RT for spinal metastases in an outpatient palliative RT clinic from January 2007 to October 2008 were retrospectively reviewed. Forty spinal metastases were evaluated. Pain response was rated using the International Bone Metastases Consensus Working Party endpoints. Three musculoskeletal radiologists and two orthopaedic surgeons evaluated CT features, including osseous and soft tissue tumor extent, presence of a pathologic fracture, severity of vertebral height loss, and presence of kyphosis. Results: The mean patient age was 69 years; 24 were men and 9 were women. The mean worst pain score was 7/10, and the mean total daily oral morphine equivalent was 77.3 mg. Treatment doses included 8 Gy in one fraction (22/33), 20 Gy in five fractions (10/33), and 20 Gy in eight fractions (1/33). The CT imaging appearance of spinal metastases included vertebral body involvement (40/40), pedicle involvement (23/40), and lamina involvement (18/40). Soft tissue component (10/40) and nerve root compression (9/40) were less common. Pathologic fractures existed in 11/40 lesions, with resultant vertebral body height loss in 10/40 and kyphosis in 2/40 lesions. At months 1, 2, and 3 after RT, 18%, 69%, and 70% of patients experienced pain relief. Pain response was observed with various CT imaging features. Conclusions: Pain response after RT did not differ in patients with and without pathologic fracture, kyphosis, or any other CT features related to extent of tumor involvement. All patients with painful spinal metastases may benefit from palliative RT.

    To assess whether clodronate can reduce frequency of skeletal morbidity in women with lytic bone metastases from breast cancer. Methods: Between 1997 and 2001,167 patients with stage IV breast cancer with bone metastases, were randomly assigned to receive clodronate at a dose of 1600 mg per day orally for 12 months, in addition to the standard specific anti cancer therapy (87 patients) or standard anti cancer therapy only (80 patients). Skeletal complications, including pathological fractures, the need for radiation to bone or bone surgery, spinal cord compression and hypercalcaemia (a serum calcium concentration above 12 mg per deci liter (3.0 mmol per liter) or elevated to any degree and requiring treatment) were assessed monthly. Bone pam. use of analgesic drugs, performance status and quality of life were assessed throughout the trial. Results: There was no significant difference between the two groups at study entry regarding clinical characteristics. The median time for first skeletal complication was ,significantly less in the control group (6.1 vs 9.7 months, ρ=0.05). The proportion of patients who had any skeletal complication in the clodronate group than the control group, but the difference was insignificant (ρ 0.09). Clodronate was generally well tolerated and the main side effects were constipation (32%) flatulence/dyspepsia (17%) and anorexia (8%). The overall survival was not affected by clodronate therapy. The median survival was 14 months In the clodronate group and 13.8 months in the control group. Conclusions: Clodronate is an effective supplement to conventional anticancer treatment for breast cancer with bone metastasis. It reduces skeletal complications and relieves symptoms associated with lytic bone lesions. Further clinical trials that recruit a larger number of patients will be needed to clearly define the role of clodronate in metastatic breast cancer

    Purpose: To explore the relationships (clusters) among the functional interference items in the Brief Pain Inventory (BPI) in patients with bone metastases. Methods: Patients enrolled in the Radiation Therapy Oncology Group (RTOG) 9714 bone metastases study were eligible. Patients were assessed at baseline and 4, 8, and 12 weeks after randomization for the palliative radiotherapy with the BPI, which consists of seven functional items: general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life. Principal component analysis with varimax rotation was used to determine the clusters between the functional items at baseline and the follow-up. Cronbach's alpha was used to determine the consistency and reliability of each cluster at baseline and follow-up. Results: There were 448 male and 461 female patients, with a median age of 67 years. There were two functional interference clusters at baseline, which accounted for 71% of the total variance. The first cluster (physical interference) included normal work and walking ability, which accounted for 58% of the total variance. The second cluster (psychosocial interference) included relations with others and sleep, which accounted for 13% of the total variance. The Cronbach's alpha statistics were 0.83 and 0.80, respectively. The functional clusters changed at week 12 in responders but persisted through week 12 in nonresponders. Conclusion: Palliative radiotherapy is effective in reducing bone pain. Functional interference component clusters exist in patients treated for bone metastases. These clusters changed over time in this study, possibly attributable to treatment. Further research is needed to examine these effects.

    The clinical picture of bone metastases is manifested by pain and loss of mechanical stability. Standard treatment options for bone metastases include external beam radiotherapy and the use of analgesics. Due to a large number of lesions in many patients, the use of radionuclide therapy with beta emitters may be preferable. Re-186 hydroxyethydilene diphosphonate (Re-186 HEDP) is one of the radiopharmaceuticals suitable for palliative treatment of metastatic bone pain. The aim of this study was to investigate palliative and side effects of Re-186 HEDP in pts with different type of cancers. Material and method: Thirty one (17 male, 14 female) patients with cancer (10 prostate, 10 breast, 4 rectum, 5 lung, 2 nasopharynx) and bone metastases were included in the study. Therapy was started with a fixed dose of 1295 MBq of Re-186 HEDP. If necessary, the same dose was repeated at least 3 times after an interval of 10-12 weeks A total of 40 standard doses (1295 MBq Re HEDP, Mallinckrodt, Holland) were given; 6 pts received repeated doses (3 doses in 3 pts, 2 doses in 3 pts). The pts with bone marrow suppression were excluded from the study. The pain relief was assessed with ECOG and Karnofsky status index. All pts were evaluated with standard evaluation forms filled daily a maximum of 10 weeks. Results: The respond rate was found as 87.5% in pts with breast and prostate Ca, 75% in pts with rectum Ca, 50% in pts with nasopharynx Ca and 20% in pts with lung Ca. The overall response rate was 67.5%. The palliation period varied between 6 to 10 weeks. The mean palliation period was 8.1 ± 1.3 weeks. Maximal palliation effect was observed between the 3 rd and the 7 th weeks. Any serious side effects were not seen except mild haematologic toxicity. Discussion and conclusion: It is concluded that Re-186 HEDP is a highly effective agent in the palliation of metastatic bone pain in pts with prostate, breast, rectum cancer, mildly effective in pts with nasopharynx cancer, but not

    Bone metastases are extremely rare in patients with classical Wilms' tumor (WT). We describe the clinical and radiologic features, treatment and outcome of three patients with WT (one with favorable histology and two with anaplasia) in whom bone metastases were detected at diagnosis or relapse. Bone metastases were documented by skeletal radiographs, computed tomography and/or bone scintigraphy. The patient with favourable histology WT had no evidence of pulmonary metastases and is now free of disease following aggressive chemotherapy and radiotherapy. (orig.)

    Full Text Available Objective To analyze the risk factors and characteristics of bone metastases in patients with prostate cancer. Methods Patients who were diagnosed as prostate cancer by biopsy and histopathologic analysis between June 2006 and June 2016 were included in this study. The clinical data of the patients were reviewed, and the demographic data, laboratory examination results and Gleason score were recorded. The correlations between clinical factors and bone metastasis were analyzed, and the risk factors of bone metastasis were identified. Results A total of 585 patients were recruited in this study, including 228 with bone metastasis and 357 without bone metastasis. Of the patients with bone metastasis, the incidence of pelvic metastasis was the highest, accounting for 81.58%, followed by spin (63.16% and rib (58.33%, and the incidence of clavicle metastasis was the lowest (14.47%. Logistic regression analysis showed that age 85.5U/L, prostate-specific antigen >79.88μg/L and Gleason score >7.5 were the risk factors of bone metastasis in prostate cancer. ROC curve analysis showed that the sensitivity of diagnosing bone metastasis was 56.1%, 66.7%, 68.4% and 56.1%, and the specificity was 56.6%, 81.8%, 70.0% and 65.3%, respectively for above 4 factors. Conclusions The most common site of bone metastasis in patients with prostate cancer is pelvis. Patients' age, concentrations of plasma ALP and PSA, and Gleason score are the risk factors for bone metastasis in patients with prostate cancer. DOI: 10.11855/j.issn.0577-7402.2017.08.09

    Primary spinal primitive neuroectodermal tumor (PNET) is relatively rare in all age groups, and the prognosis in most cases of spinal PNETs appears to be poor, with a median patient survival of 1 to 2 years. We present a case with recurrent spinal PNET with brain and bone metastases that was successfully treated by multimodality treatment. A 14-year-old teenage girl had suffered from progressive left upper back pain with bilateral lower legs weakness and numbness for 1 year. After treatment, left neck mass was noted 3 years later. Initially, magnetic resonance imaging (MRI) showed neurogenic tumor involving intradural extramedullary space of T5-T10. Pathology report showed PNET (World Health Organization grade IV) featuring lobules of neoplastic cells with round regular nuclei, high nucleus-to-cytoplasm ratio, and fibrillary cytoplasm. At the time of tumor recurrence, chest MRI then showed recurrent tumor at T2-T3 level of the epidural space with right neural foramina invasion. Brain MRI showed extensive bilateral calvarial metastases and leptomeningeal metastases in the right frontoparietal regions. Bone scan showed multiple bone metastases. T-spine tumor removal and adjuvant radiotherapy (RT) to T-spine tumor bed were performed in the initial treatment. After clinical tumor recurrence, tumor removal was done again. She then received chemotherapy followed by whole brain irradiation with hippocampal sparing with 35 gray in 20 fractions. After treatment, follow-up images showed that the disease was under control. There was no neurological sequela. She has survived more than 7 years from diagnosis and more than 4 years from recurrence to date. Multimodality treatments including operation, RT, and chemotherapy should be considered in the initial treatment planning, and salvage chemotherapy was useful in this case.

    Full Text Available Purpose. We report a series of 58 patients with metastatic bone disease treated with resection and endoprosthetic reconstruction over a five-year period at our institution. Introduction. The recent advances in adjuvant and neoadjuvant therapy in cancer treatment have resulted in improved prognosis of patients with bone metastases. Most patients who have either an actual or impending pathological fracture should have operative stabilisation or reconstruction. Endoprosthetic reconstructions are indicated in patients with extensive bone loss, failed conventional reconstructions, and selected isolated metastases. Methods and Results. We identified all patients who were diagnosed with metastatic disease to bone between 1999 and 2003. One hundred and seventy-one patients were diagnosed with bone metastases. Metastatic breast and renal cancer accounted for 84 lesions (49%. Fifty-eight patients with isolated bone metastasis to the appendicular skeleton had an endoprosthetic reconstruction. There were 28 males and 30 females. Twelve patients had an endoprosthesis in the upper extremity and 46 patients had an endoprosthesis in the lower extremity. The mean age at presentation was 62 years (24 to 88. At the time of writing, 19 patients are still alive, 34 patients have died, and 5 have been lost to follow up. Patients were followed up and evaluated using the musculoskeletal society tumour score (MSTS and the Toronto extremity salvage score (TESS. The mean MSTS was 73% (57% to 90% and TESS was 71% (46% to 95%. Mean follow-up was 48.2 months (range 27 to 82 months and patients died of disease at a mean of 22 months (2 to 51 months from surgery. Complications included 5 superficial wound infections, 1 aseptic loosening, 4 dislocations, 1 subluxation, and 1 case, where the tibial component of a prosthesis rotated requiring open repositioning. Conclusions. We conclude that endoprosthetic replacement for the treatment of isolated bone metastases is a reliable

    Accurate staging of cancer has a critical role in optimal patient management. Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) is superior to CT in the detection of local and distant metastases in patients with non-small cell lung cancer. Although Tc-99 m methylene diphosphonate (MDP) bone scanning is well established in the evaluation of bone metastases, there are conflicting reports on the use of FDG PET in the evaluation of skeletal metastases. We report on a patient with locally advanced lung carcinoma in whom FDG PET accurately identified previously unsuspected widespread asymptomatic bone metastases (bone scan and X-rays negative, confirmed on MRI). Assessment of glucose metabolism with FDG PET might represent a more powerful tool to detect bone metastases in lung cancer compared with conventional bone scans Copyright (2004) Blackwell Publishing Asia Pty Ltd

    Purpose: Data in the literature suggest that for painful bone metastases a single dose is as effective as fractionated radiotherapy. In the present multicentre prospective trial, the effects of 8 Gy x1 and 5 Gy x4 were compared. Patients and methods: A total of 241 patients were randomized to 8 Gy (122 patients) or 20 Gy (119 patients). The primary tumour was in the breast in 39% of patients, in the prostate in 34% of patients, in the lung in 13% of patients and in other locations in 14% of patients. Outcome measures were pain relief as measured by VAS and in half of the patients also by a five-point categorical pain scale, global quality of life (QoL) and analgesic consumption. Evaluation was performed before and 4, 8, 12 and 20 weeks after treatment. Results: A total of 239 patients were evaluable for response. The two groups did not differ with respect to age, sex, primary tumour, metastasis localization, analgesic consumption (type and dose), performance status, prior systemic treatment, degree of pain and QoL. The treatment was completed as planned in 98% of patients. The degree of pain relief did not differ between the two treatment groups. At 4 weeks the difference in pain relief was 6% (95% CI 7, 20%) and at 8 weeks the difference was 13% (95% CI 3, 28%). Neither was there any significant difference in the duration of pain relief, the number of new painful sites and the need for reirradiation and toxicity was minor. Conclusion: The present randomized study showed that a single fraction of 8 Gy was as effective as 5 Gy x4 in relieving pain from bone metastasis.

    The aim of this study was evaluation of the clinical usefulness of bone scintigraphy and of serum bone turnover marker levels in the assessment of skeletal metastases. We investigated 60 patients with suspected skeletal metastases. Serum level of bone-formation marker: amino- terminal propeptide of type I procollagen (PINP) and a bone-degradation marker: carboxy-terminal telopeptide of type I collagen (ICTP) were assessed with radioimmunoassays. Bone MDP- 99m- Tc scans were performed as well. Hot spots were showed in 72% of patients. According to bone scintigraphy the patients were divided in to 3 groups: Group I - without hot spots (n = 16; 26%), Group II up to 10 hot spots (n = 25; 42%) and Group III more that 10 hot spots (n = 19; 32%). Mean serum level of ICTP was significantly higher in Group II than in Group I (p < 0.05), as well as in Group III compared to Group II (p < 0.001) and in Group III compared to Group I (p < 0.001). There is only one significant relationship in PINP levels - between Groups II and III. The levels of bone pathological degradation (ICTP) and bone formation reflect the metastatic disease extent in bone. Serum ICTP level is more useful in staging metastasis. Significantly higher PINP reflects only a much disseminated process. (author)

    Numerous randomised clinical trials have shown that the efficacy of single fraction radiotherapy for metastatic bone pain corresponds to that of multiple fractions of radiotherapy for the majority of patients. It is not clear to which extent single fraction radiotherapy has been implemented into clinical practice. Material and methods: A Norwegian national registry based study was conducted, including all radiotherapy schedules of 8 Gy x 1 and 3 Gy x 10 delivered to bone metastases in 1997 - 2007. Binomial regression analyses were used to study whether treatment centre, primary diagnosis, anatomical region irradiated, age, sex, and travel distance, were associated with the choice of fractionation. Results: A total of 14 380 radiotherapy episodes were identified. During the period 31% of the treatments were delivered as 8 Gy x 1. The proportion of single fraction treatments increased from 16% in 1997 to 41% in 2007. There were substantial differences in the proportion of single fraction treatments between the treatment centres (range 25 - 54%). These differences persisted after adjustment for sex, age, primary diagnosis, anatomical region, and travel distance. Conclusions: The study demonstrates an under utilisation of single fraction treatment for bone metastases in Norway during the study period.

    Prognosis of patients affected with hepatocellular carcinoma (HCC) has been improved by the modern imaging techniques allowing an early diagnosis and by the value of the therapeutic protocols employed. Staging has also become more and more important. Bone metastases from HCC are reportedly rare. The authors observed a 5.5 incidence in 90 cases of hepatocarcinoma. The metastases were demonstrated by radiography, CT, and nyclear scintigraphy, in patients with skeletal pain. The plain film appearance of skeletal metastases from Hcc was osteolytic in all cases; no surrounding sclerosis was seen. CT scans demonstrated the destructive nature of these lesions, which were associated with bulky soft-tissue masses. Metastases exhibited increased radiotracer ({sup 99m}Tc-MDP) uptake at bone scintigraphy. The authors believe that bone scintigraphy should be included in the staging protocols of the HCCs which need a potentially curative therapy. 28 refs.

    Histograms which show uptake rate distribution on bone metastases and on normal bones, arthrosic bone, uncalcified bone, have been drawn up. 819 scans performed on 627 patients have been classified according to ratio of bone segment/knee, bone segment/whole body and bone segment/minimum (knee, whole body). Henry's straight lines have been drawn in man and in woman for these different ratios in order to select the best discriminant. At last a biopsy on 97 patients has controlled the validity of the method. Quantitative scanning allows, on the other hand, to observe the evaluation of metastases under treatment as shown by the fixation curves during this time [fr

    We evaluated the radiological response and clinical outcome in patients with femoral bone metastases after radiotherapy. 102 consecutive patients with femoral metastases without pathological fracture were treated by surgery or radiotherapy between 2002 and 2005. Twelve of them initially treated with surgery were excluded from this study. The remaining 90 patients with 102 lesions underwent radiation therapy as the initial treatment. Twelve patients who died within 30 days by disease progression and 6 who were lost to follow-up were excluded. The remaining 72 patients with 84 lesions including 43 impending fractures were enrolled in this analysis. Radiological changes were categorized into complete response, partial response, no change, and progressive disease based on plain radiograph findings. Pain relief was reviewed for 77 painful lesions. The median radiation dose was 30 Gy. No re-irradiation was performed. 35 lesions (42%) achieved radiological responses median 3 months after radiotherapy. Pain relief was obtained in 36 of 77 lesions (47%). There was no significant correlation between radiological response and pain relief (P=0.166). Eleven lesions eventually required surgery and considered as treatment failure. The treatment failure rate in the radiological progressive disease (PD) group (8/19, 42%) was significantly higher than that in the non-PD group (3/65, 5%) (P<0.001). Among 43 impending fracture lesions, 15 lesions (36%) experienced radiological response and 35 lesions (81%) required no surgical interventions. Our data suggest that radiotherapy can enable metastatic bone healing and avoid surgery in many lesions. However, radiological PD lesions often require surgery after radiotherapy. (author)

    Full text: Bone metastases are a frequent complication of cancer, occurring in up 70% of patients suffering from advanced breast or prostate cancer and often present with severe bone pain. In this purpose the radionuclide therapy is a useful option for cancer patients. Different radionuclides are described, such as 89 Sr, 32 P, 153 Sm-EDTMP, 186 Re-HEDP, 131 I-BDP3, 90 Y, 117mSn-DTPA, 188 Re-HEDP and 188 Re-DMSA. The most experiences are available for 89 Sr. An indication for the treatment are patients with osteoblastic metastases, bone pain, sufficient bone marrow function and at least of three bone metastases visualized in bone scan. A bisphosphonate therapy, a chemotherapy with lower bone marrow toxicity or a local field external beam radiotherapy represent no contraindications, especially because the reported synergistic effects to the systemic radionuclide therapy. In 33 treated patients (breast and prostate cancer) we investigated the effect of 188 Re-HEDP on pain relief, analgesic intake and impairment of bone marrow function. There were an improvement on the Karnofsky performance scale from 74 7% to 85 9% 12 weeks after therapy (p= 0.001). The pain score showed a maximum decrease from 44 ± 18% to 27 ± 20% in the 3rd to the 8th week after therapy (p = .009) and 76% had a pain relief (20% were pain free). The maximal differences between the values of platelets and leukocytes before and after therapy were not statistically significant (p = 0.021 and p = 0.094). In 105 investigated patients treated with different radionuclides ( 89 Sr, 153 Sm-EDTMP, 186 Re-HEDP, 188 Re-HEDP and 89 Sr in combination with chemotherapy) no different therapeutic efficacy of the treatments were observed. In dose calculation of 188 Re-HEDP a radiation dose of 3.83 ± 2.01 mGy/MBq (12.6 Gy for 3300 MBq) for bone metastases and 0.61 ± 0.21 mGy/MBq (2 Gy for 3300 MBq) were found. With the introducing of radionuclide treatments with chemotherapy and repeated treatments, the

    Full Text Available Ursa Brown-Glaberman, Alison T StopeckUniversity of Arizona Cancer Center, Tucson, AZ, USAAbstract: Skeletal-related events (SREs including pain, fractures, and hypercalcemia are a major source of morbidity for cancer patients with bone metastases. The receptor activator of NF-κB ligand (RANKL is a key mediator of osteoclast formation and activity in normal bone physiology as well as cancer-induced bone resorption. The first commercially available drug that specifically targets and inhibits the RANKL pathway is denosumab, a fully human monoclonal antibody that binds and neutralizes RANKL, thereby inhibiting osteoclast function. In this review, we summarize the major studies leading to the US Food and Drug Administration-approval of denosumab for the prevention of SREs in patients with bone metastases from solid tumors. Further, we discuss the role of denosumab in the prevention and treatment of SREs and bone loss in cancer patients. As a monoclonal antibody, denosumab has several advantages over bisphosphonates, including improved efficacy, better tolerability, and the convenience of administration by subcutaneous injection. In addition, as denosumab has no known renal toxicity, it may be the preferred choice over bisphosphonates in patients with baseline renal insufficiency or receiving nephrotoxic therapies. However, other toxicities, including osteonecrosis of the jaw and hypocalcemia, appear to be class effects of agents that potently inhibit osteoclast activity and are associated with both denosumab and bisphosphonate use. The data presented highlight the differences associated with intravenous bisphosphonate and denosumab use as well as confirm the essential role bone-modifying agents play in maintaining the quality of life for patients with bone metastases.Keywords: denosumab, bone metastases, solid tumor, breast cancer, prostate cancer, skeletal related events, skeletal complications

    Full Text Available Abstract Background Breast cancer (BrCa is the most commonly diagnosed cancer among women in the industrialized world. More than half of women presenting with metastatic BrCa develop bone metastases. Bone metastases increase the risk of skeletal-related events (SREs, defined as pathological fractures, spinal cord compression, bone pain requiring palliative radiotherapy, and orthopaedic surgery. Both bone metastases and SREs are associated with unfavorable prognosis and greatly affect quality of life. Few epidemiological data exist on SREs after primary diagnosis of BrCa and subsequent bone metastasis. We therefore estimated the incidence of bone metastases and SREs in newly-diagnosed BrCa patients in Denmark from 1999 through 2007. Methods We estimated the overall and annual incidence of bone metastases and SREs in newly-diagnosed breast cancer patients in Denmark from January 1, 1999 to December 31, 2007 using the Danish National Patient Registry (DNPR, which covers all Danish hospitals. We estimated the cumulative incidence of bone metastases and SREs and associated 95% confidence intervals (CI using the Kaplan-Meier method. Results Of the 35,912 BrCa patients, 178 (0.5% presented with bone metastases at the time of primary breast cancer diagnosis, and of these, 77 (43.2% developed an SRE during follow up. A total of 1,272 of 35,690 (3.6% BrCa patients without bone metastases at diagnosis developed bone metastases during a median follow-up time of 3.4 years. Among these patients, 590 (46.4% subsequently developed an SRE during a median follow-up time of 0.7 years. Incidence rates of bone metastases were highest the first year after the primary BrCa diagnosis, particularly among patients with advanced BrCa at diagnosis. Similarly, incidence rates of a first SRE was highest the first year after first diagnosis of a bone metastasis. Conclusions The high incidence of SREs following the first year after first diagnosis of a bone metastasis

    Aim: Influenced by the incorrect diagnosis of a bone metastasis caused by bone necrosis we evaluated reasons and frequency of bone necrosis in patients referred for bone scanning in follow-up of tumors. Methods: Bone scans performed within two years on patients with primary bone tumors or tumors metastatic to bone were reviewed in respect to the final diagnosis bone necrosis. Results: We found the cases of three young patients who presented the appearance of hot spots on bone scintigrams which were finally diagnosed as bone necrosis. In two cases the diagnosis was based on histological findings, in one case the diagnosis was made evident by follow-up. All the three patients had been treated by chemotherapy and presented no other reason for the development of bone necrosis. Enhanced tracer uptake in all sites decreased within eight weeks up to two years without therapy. Conclusion: Single and multiple hot spots after chemotherapy may be originated by bone necrosis but mimikry metastases. (orig.) [de

    Full Text Available Percutaneous vertebroplasty (PVP has been shown to release spinal pain and stabilize the vertebral body. PVP is suggested as an alternative treatment in spinal metastasis. Although cervical metastases is less prevalent than thoracic and lumbar spine, PVP procedure in cervical vertebrae remains technical challenging. We retrospectively analyzed the data from patients (n=9 who underwent PVP using anterolateral approach to treat severe neck pain and restricted cervical mobility from metastatic disease. Patients were rated using modified Tokuhashi score and Tomita score before the procedure. Visual analog scale (VAS, neck disability index (NDI, analgesic use, and imaging (X-ray or CT were evaluated before PVP and 3 days, 3 months, and 6 months after PVP. All patients were in late stage of cancer evaluated using modified Tokuhashi and Tomita score. The cement leakage rate was 63.6% (14 of the 22 vertebrae with no severe complications. VAS, NDI, and analgesic use were significantly decreased 3 days after the procedure and remained at low level until 6 months of follow-up. Our result suggested PVP effectively released the pain from patients with cervical metastasis. The results warrant further clinical investigation.

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

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

    The inclusion of scintigraphy in the repertory of diagnostic techniques is quite recent, but this examination is continually gaining in importance. In the case of bone metastases it certainly contributes to early diagnosis, a factor which is still the foremost condition of therapeutic efficiency. However some faults persist in the detection of metastases and it is hoped that the isotopic technique will gradually eliminate these errors. Scintigraphy in fact is still in its infancy, and several products are used for want of a consensus. Many improvements are expected in the future, whether in the technique itself or in its reliability or interpretation. - Technical improvement with the appearance of more sensitive instruments, tomography... - Improved interpretation by the acquisition of images on which hypofixation and hyperfixation zones will be more clearly differentiated and by a more accurate, more mathematical estimation of hypofixation and hyperfixation. Progress is already very rapid in this respect owing to the arrival of computerization. - Better reliability, perhaps the field in which hopes are highest: discovery of new radioactive products acting selectively in the metabolism or catabolism of the neoplasic process. Scintigraphy is a technique undoubtedly destined for considerable further development and called on to play an increasingly important part in cancer diagnosis and even in research on the cancer call development process itself [fr

    Accurate staging of cancer has a critical role in optimal patient management. Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) is superior to CT in the detection of local and distant metastasesin patients with non-small cell lung cancer. Although Tc-99 m methylene diphosphonate (MDP) bone scanning is well established in the evaluation of bone metastases, there are conflicting reports on the use of FDG PET in the evaluation of skeletal metastases. We report on a patient with locally advanced lung carcinoma in whom FDG PET accurately identified previously unsuspected widespread asymptomatic bone metastases (bone scan and X-rays negative, confirmed on MRI). Assessment of glucose metabolism with FDG PET might represent a more powerful tool to detect bone metastases in lung cancer compared with conventional bone scans.

    The purpose of this study was to determine the effect of interventional palliative therapy by using chemoembolization on metastatic bone pain and tumor bulk in inoperable metastases where chemotherapy and radiotherapy had failed. Twenty-five patients (mean age: 59 years) underwent chemoembolization of symptomatic lytic lesions involving the spinal column (n=10), iliac bone and sacrum (n=15). The study design consisted of at least three procedures based on combined chemoembolization performed under analog-sedation. Therapeutic agents were carboplatin for selective chemotherapy and pirarubicin mixed with polyvinyl alcohol foam for chemoembolization. Fifteen of 18 (83%) patients had significant pain relief, as shown by the decrease of analgesic drug use. Mean clinical response duration was 12 months. Radiologically, ten patients were stable. A partial response was observed in four patients, while a complete response was seen in two others. Selective intra-arterial chemoembolization gives longer pain relief than embolization, compared to the literature data, probably because of partial response with local anti-cancer drugs. (orig.)

    Objective: To evaluate the effect of 153 Sm-EDTMP in treating patients with lung cancer and multiple bone metastases. Methods: A dose of 18.5-25.9 MBq/Kg 153 Sm-EDTMP was administered once a month to each patient through vein injection according to disease severity and body weight. 3 injections made up one therapy cycle. Results: Pain relieves were obtained in 65 patients, with an effective rate of 83.3%. Pain relief of grade I was observed in 19 patients (24.3%), grade II in 46 patients (59%) and grade III in 13 patients (16.7%), respectively. Lesions of bone metastases disappeared or shrunk in 9 patients, with a positive rate of 11.5%, which included 3 cases of grade I and 6 cases of grade II, respectively. Better effects were obtained in adenocarcinoma and squamous carcinoma than in small cell lung cancer. Conclusion: 153 Sm-EDTMP is safe and effective in treating patients with lung cancer and multiple bone metastases

    Full Text Available Denise A Yardley1,2 1Sarah Cannon Research Institute, Nashville, TN, USA; 2Tennessee Oncology, Nashville, TN, USA Abstract: There is a high risk for bone loss and skeletal-related events, including bone metastases, in postmenopausal women with hormone receptor-positive breast cancer. Both the disease itself and its therapeutic treatments can negatively impact bone, resulting in decreases in bone mineral density and increases in bone loss. These negative effects on the bone can significantly impact morbidity and mortality. Effective management and minimization of bone-related complications in postmenopausal women with hormone receptor-positive breast cancer remain essential.

    The detailed examination of the skeleton in prostate cancer has become more critical since surgical treatment requires the non-evidence of bone metastases. The data of 30 patients have been evaluated. All patients had a bone scan and a bone marrow scintigraphy with [ 99m Tc[-anti-NCA95. In this study we compared the degree of bone marrow displacement with the extent of metastatic deposits identified on the bone scan. Six patients showing the criterias of a superscan (maximal avidity of the osteotrope radiatracer) had as a correlate a complete displacement of the hematopoesis in the bone marrow scintigraphy and an increased activity in liver and spleen. The degree of the peripheral extension correlated strongly with the decrease of the haemoglobin in blood samples. The grading was based upon the number of metastatic deposits identified on the scan (0=no metastases; 1≤6 metastases; 2=multiple metastases; 3=superscan). In 28 of 30 patients (93%) we found corresponding results in both the bone scan and the bone marrow scintigraphy. The bone marrow scintigraphy is a sensitive method in the detection of metastatic disease and gives additional information about the extent of bone marrow displacement by osteoplastic metastases.

    Full Text Available Bone is one of the most preferential target site for cancer metastases, particularly for prostate, breast, kidney, lung and thyroid primary tumours. Indeed, numerous chemical signals and growth factors produced by the bone microenvironment constitute factors promoting cancer cell invasion and aggression. After reviewing the different theories proposed to provide mechanism for metastatic progression, we report on the gene expression profile of bone-seeking cancer cells. We also discuss the cross-talk between the bone microenvironment and invading cells, which impacts on the tumour actions on surrounding bone tissue. Lastly, we detail therapies for bone metastases. Due to poor prognosis for patients, the strategies mainly aim at reducing the impact of skeletal-related events on patients’ quality of life. However, recent advances have led to a better understanding of molecular mechanisms underlying bone metastases progression, and therefore of novel therapeutic targets.

    The results from a prospective randomized trial comparing two different radiation schedules for treatment of painful bone metastases in women with recurrent breast cancer are presented. A total of 217 patients with painful bone metastases were randomized to either 30 Grey (Gy) in ten fractions, five fractions a week ((5F(W))) or 15 Gy in three fractions(2F(W)) . The effect of treatment was evaluated by pain assessment, the radiological response and the degree of side-effects. The patients were rated at start of treatment and after 1, 3, 6 and 12 months. No difference between the two radiation regimes was found, neither in achieved pain relief, improvement in level of activity and medication, nor was there any difference in radiological response and side-effects from treatment. Both regimes resulted in a significant improvement in both pain score and level of activity 1 month after treatment, an improvement which persisted during the follow-up period. We conclude that 15 Gy given in three fractions (2F(W)) is as effective as 30 Gy in ten fractions (5F(W)), but more convenient to the patient and of less cost to society

    Full Text Available Sex-associated differences in bone metastasis formation from breast, lung, and prostate cancer exist in clinical studies, but have not been systematically reviewed. Differences in the bone marrow niche can be attributed to sexual dimorphism, to genetic variations that affect sex hormone levels, or to the direct effects of sex hormones, natural or exogenously delivered. This review describes the present understanding of sex-associated and sex hormone level differences in the marrow niche and in formation of bone metastasis during the transition of these three cancers from treatable disease to an often untreatable, lethal metastatic one. Our purpose is to provide insight into some underlying molecular mechanisms for hormonal influence in bone metastasis formation, and to the potential influence of sexual dimorphism, genetic differences affecting sex assignment, and sex hormone level differences on the bone niche and its favorability for metastasis formation. We reviewed publications in PubMed and EMBASE, including full length manuscripts, case reports, and clinical studies of relevance to our topic. We focused on bone metastasis formation in breast, lung, and prostate cancer because all three commonly present with bone metastases. Several clear observations emerged. For breast cancer bone metastasis formation, estrogen receptor (ER signaling pathways indicate a role for ER beta (ERβ. Estrogen influences the bone microenvironment, creating and conditioning a favorable niche for colonization and breast cancer progression. For lung cancer, studies support the hypothesis that females have a more favorable bone microenvironment for metastasis formation. For prostate cancer, a decrease in the relative androgen to estrogen balance or a “feminization” of bone marrow favors bone metastasis formation, with a potentially important role for ERβ that may be similar to that in breast cancer. Long-term estrogen administration or androgen blockade in males

    Metastatic bone pain is a complex, poorly understood process. Understanding the unique mechanisms causing cancer-induced bone pain may lead to potential therapeutic targets. This article discusses the effects of osteoclast overstimulation within the tumor microenvironment; the role of inflammatory factors at the tumor-nociceptor interface; the development of structural instability, causing mechanical nerve damage; and, ultimately, the neuroplastic changes in the setting of sustained pain. Several adjuvant therapies are available to attenuate metastatic bone pain. This article discusses the role of pharmacologic therapies, surgery, kyphoplasty, vertebroplasty, and radiofrequency ablation. Copyright © 2018 Elsevier Inc. All rights reserved.

Methods: Forty-two patients with proved bone metastases were treated with 89 SrCl 2 and according to the final therapeutic efficiency for the metastatic lesions, the patients were divided into efficacious and inefficacious group. Twenty untreated healthy adults served as control group. The T lymphocyte subsets CD 4 + , CD 8 + , CD 4 + /CD 8 + were analyzed before and after 89 SrCl 2 treatment. Results: The immunological indexes were not significantly different between the two patient groups before the therapy of 89 SrCl 2 . The indexes between the controls and patients before and after the therapy were different significantly (P 89 SrCl 2 , 37 (88.10%) patients' immunological functions were improved, 33 patients (78.57%) stated that their pain were effectively relieved, 29 (69.05%) patients' bone metastatic lesions reduced. Conclusions: The immunological functions in the patients with bone metastases were inhibited obviously. Treating with 89 SrCl 2 can improve their immunological functions to a certain extent. The recovery level of the inefficacious patients was lower than that of the efficacious patients. The changes of immunological functions can reflect the therapeutical effectiveness. (authors)

    Once tumours metastasize to bone, they are usually incurable and responsible for several devastating consequences: severe pain, pathologic fractures, life-threatening hypercalcemia, spinal cord compression and other nerve-compression syndromes. Understanding of physiopathological mechanisms responsible for these symptoms is critical for therapeutic approach, especially pain treatments. Three types of pain occur in tumour bone involvement: tonic or background pain, which are deep non-specific ache rising in intensity as the disease progresses; incident pain on movement (allodynia); and spontaneous pain which can be severe. Bone metastases could be osteolytic or osteoblastic. However, this classification actually represents two extremes of a continuum characterized by dys-regulation of the normal bone remodeling process. Biochemical mediators production is crucial as a part of this process. The bone microenvironment plays a critical role in the formation of osteoclasts through the production of macrophage colony-stimulating factor, receptor activator of nuclear factor kB ligand (RANKL)... Many of these mediators of osteolysis also have been shown to activate nociceptors: prostaglandins A and E, IL-1, IL-6, TNF. Thus there is a link between osteolytic destruction, inflammation and pain. It explains that severe pain could occur independently from fractures and in absence of any bone structure alteration and nervous compression. Also, pain is often disproportionate to tumour size or degree of bone involvement. Inflammatory and osteolytic processes depend on number, localization and organization of tumour cells inside bone and bone marrow tissues. All these parameters are crucial to take into account for a good understanding of treatments mechanisms of action, especially anti-inflammatory drugs (corticosteroid and others), bi-phosphonates, internal radiotherapy (strontium 89 or radiolabelled bi-phosphonates), external radiotherapy and chemotherapy or hormonotherapy

    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)

    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.

    Bone is the most common site of breast cancer distant metastasis, affecting 50–70 % of patients who develop metastatic disease. Despite decades of informative research, the effective prevention, prediction and treatment of these lesions remains elusive. The Breast Cancer to Bone (B2B) Metastases Research Program consists of a prospective cohort of incident breast cancer patients and four sub-projects that are investigating priority areas in breast cancer bone metastases. These include the impact of lifestyle factors and inflammation on risk of bone metastases, the gene expression features of the primary tumour, the potential role for metabolomics in early detection of bone metastatic disease and the signalling pathways that drive the metastatic lesions in the bone. The B2B Research Program is enrolling a prospective cohort of 600 newly diagnosed, incident, stage I-IIIc breast cancer survivors in Alberta, Canada over a five year period. At baseline, pre-treatment/surgery blood samples are collected and detailed epidemiologic data is collected by in-person interview and self-administered questionnaires. Additional self-administered questionnaires and blood samples are completed at specified follow-up intervals (24, 48 and 72 months). Vital status is obtained prior to each follow-up through record linkages with the Alberta Cancer Registry. Recurrences are identified through medical chart abstractions. Each of the four projects applies specific methods and analyses to assess the impact of serum vitamin D and cytokine concentrations, tumour transcript and protein expression, serum metabolomic profiles and in vitro cell signalling on breast cancer bone metastases. The B2B Research Program will address key issues in breast cancer bone metastases including the association between lifestyle factors (particularly a comprehensive assessment of vitamin D status) inflammation and bone metastases, the significance or primary tumour gene expression in tissue tropism, the

    Palliative radiotherapy is effective in the treatment of bone metastases but is under-utilized, possibly because it is perceived to be expensive. We performed a cost-utility analysis of palliative radiotherapy for bone metastases, evaluating both the actual cost of radiotherapy as well as its impact on quality of life by adjusting for the variation in response to treatment. Hospital records between July 1991 and July 1996 were reviewed to ascertain the number of patients treated with palliative radiotherapy for bone metastases, the average number of fields of radiation delivered to each patient and the average duration of survival. Partial and complete response rates to palliative radiotherapy were obtained from a review of all published randomized controlled trials of radiation treatment of bone metastases. Utility values were assigned to the response rates, and an overall adjusted response rate to radiotherapy was derived. The cost of delivering a field of radiation was calculated. The total cost was divided by the total number of response months to give a utility-adjusted cost per month of palliative radiotherapy. The utility-adjusted cost per month of palliative radiotherapy of bone metastases was found to be AUS$ 100 per month or AUS$ 1200 per utility-adjusted life-year. This study demonstrates that, contrary to popular perception, palliative radiotherapy is a cost-effective treatment modality for bone metastases. Copyright (2003) Blackwell Science Pty Ltd

    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

    To evaluate the local response according to stability after radiotherapy (RT) with a special focus on quality-of-life (QoL), fatigue, pain and emotional distress in patients with unstable spinal bone metastases. In this prospective trial, 30 patients were treated from September 2011 until March 2013. The stability of osteolytic metastases in the thoracic and lumbar spine was evaluated on the basis of the Taneichi-score after three and six months. EORTC QLQ-BM22, EORTC QLQ-FA13, and QSC-R10 were assessed at baseline, and three months after RT. After 3 months, 25% (n = 6) and after 6 months 33.3% (n = 8) were classified as stable. QoL, fatigue, and emotional distress showed no difference over the course. The pain response 3 months after RT showed a significant difference (p < 0.001). Pathological fractures occurred in 8.3% of the patients (n = 2) within six months following RT. Our trial demonstrated that RT can improve stability in one third of patients over a 6-months period with unstable spinal metastases. Importantly, for these patients pain relief was detected but RT had no impact on QoL, fatigue, and emotional distress

    MRI is an effective tool in evaluating bone marrow metastases. However, no study has defined which MRI sequences or image characteristics best correlate with bone-marrow metastases in neuroblastoma. To identify and refine MRI criteria and sequence selection for the diagnosis of bone-marrow metastases in children with neuroblastoma. Ninety-one children (mean age: 3.2 years; standard deviation: 2.8 years) enrolled in the RDOG IV study participated in our study. Forty-five children had bone metastases determined by bone-marrow aspiration or biopsy (n=4), radionuclide imaging (n=2), or both (n=39). Spine lesions were characterized using coronal T1-weighted (T1W) sagittal short tau inversion recovery (STIR) and coronal gadolinium-enhanced T1-weighted (GAD) MR sequences. Contingency table analysis was performed to determine which MRI sequences and characteristics were associated with metastases. The MRI criteria for metastatic disease were then developed for each imaging sequence. The sensitivity, specificity, predictive values, and accuracy of these criteria were determined for the whole group, children younger than 12 months old, and children 12 months and older. The MR characteristics that had significant (P ≤ 0.05) associations with metastases were homogeneous low T1-signal intensity, homogeneous high STIR-signal intensity, and heterogeneous pattern on T1, STIR, or GAD. Homogeneous low T1-signal had the highest sensitivity (88%), but a specificity of 62% for detecting metastases. A heterogeneous pattern on GAD was highly specific (97%), but relatively insensitive (65%) for detecting metastases. These MR characteristics were most accurate in children 12 months and older. The combination of non-contrast-enhanced T1W and GAD sequences can be used to determine the presence of spinal metastases in children with neuroblastoma, particularly those children who are 1 year and older.

    The aim of this retrospective study was to evaluate the stability of spinal metastases in gynecologic cancer patients (pts) on the basis of a validated scoring system after radiotherapy (RT), to define prognostic factors for stability and to calculate survival. Fourty-four women with gynecologic malignancies and spinal bone metastases were treated at our department between January 2000 and January 2012. Out of those 34 were assessed regarding stability using the Taneichi score before, 3 and 6 months after RT. Additionally prognostic factors for stability, overall survival, and bone survival (time between first day of RT of bone metastases and death from any cause) were calculated. Before RT 47% of pts were unstable and 6 months after RT 85% of pts were stable. Karnofsky performance status (KPS) >70% (p = 0.037) and no chemotherapy (ChT) (p = 0.046) prior to RT were significantly predictive for response. 5-year overall survival was 69% and 1-year bone survival was 73%. RT is capable of improving stability of osteolytic spinal metastases from gynecologic cancer by facilitating re-ossification in survivors. KPS may be a predictor for response. Pts who received ChT prior to RT may require additional bone supportive treatment to overcome bone remodeling imbalance. Survival in women with bone metastases from gynecologic cancer remains poor

    Objective: To study the correlation between the level of serum tumor makers and bone metastases of lung cancer. Method: In 128 diagnosed patients with lung cancer, small cell lung cancer were 26 cases, non-small cell lung cancer were 102 cases which included 44 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 4 cases of large cell carcinoma, 4 cases of squamous adenocarcinoma. "9"9"mTc-MDP whole-body bone scanning was performed in 128 patients with lung cancer. over the same period, the serum samples were collected in these patients and 30 comparison controls. CEA, CA125, CA199, SCC, NSE, CA15-3, and AFP were measured by ELISA technique. Bone imaging findings analysis used t-test, and serum levels of tumor markers analysis used χ"2 test. Results: The diagnostic of 53 cases of lung cancer with bone metastasis was subject to clinical criteria of lung cancer with bone metastases. The positive ratio of patients with osseous metastasis was confirmed by "9"9"mTc-MDP whole-body bone scanning was 23.44% (30/128), including 16 cases of lung adenocarcinoma, 9 cases of squamous cell carcinoma, 3 cases of small cell lung cancer , 1 case of large cell lung cancer, 1 case of squamous adenocarcinoma and multiple bone metastases accounted for 66.67% (20/30). The levels of serum CEA, CA125, CA199, SCC, NSE and CA15-3 were higher than the control group (P < O.05). 29 cases of CEA positive and 21 cases of CA125 positive were included in 30 cases of lung cancer with bone metastasis. There was a significant difference between the levels of CEA, CA125, CA199, NSE in lung cancer with bone metastases and without bone metastases (P < 0.05). The sensitivity of "9"9"mTc-MDP whole-body bone scanning in diagnosis of lung cancer with bone metastasis was 84.91%. Conclusion: The average value of CEA, CA125, and CA199, SCC, NSE and CA15-3 in lung cancer patients were significantly higher than the control group. In addition, there is a significantly correlation between the occurrence

    Full Text Available Gastrointestinal stromal tumors (GISTs are rare, but represent the most common mesenchymal neoplasms of the gastrointestinal tract. Tumor resection is the treatment of choice for localized disease. Tyrosine kinase inhibitors (imatinib, sunitinib are the standard therapy for metastatic or unresectable GISTs. GISTs usually metastasize to the liver and peritoneum. Bone metastases are uncommon. We describe three cases of bone metastases in patients with advanced GISTs: two women (82 and 54 years of age, and one man (62 years of age. Bones metastases involved the spine, pelvis and ribs in one patient, multiple vertebral bodies and pelvis in one, and the spine and iliac wings in the third case. The lesions presented a lytic pattern in all cases. Two patients presented with multiple bone metastases at the time of initial diagnosis and one patient after seven years during the follow-up period. This report describes the diagnosis and treatment of the lesions and may help clinicians to manage bones metastases in GIST patients.

    2013-01-01

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

The skeletal roentgenograms performed immediately after the scintigram confirmed osseous metastases in 60.9% of the cases, after 3 months in 76.5%, after 6 months in 81.5% and, finally, after 12 months the metastases were radiologically confirmed in 89.3% of the cases. The reasons of no confirmation of metastases in 10.7% of the cases are discussed. (Author) [pt

    AIM OF STUDY: The primary aim of this study was to evaluate the effect of half-body irradiation (HBI) on pain and quality of life in cancer patients with multiple bone metastases. The secondary aim was to evaluate side effects of the treatment. PATIENTS AND METHODS: A total of 44 patients received...... lower (n = 37), upper (n = 5), or sequential HBI (n = 2). The dose for lower HBI was 8 Gy in one fraction and for upper HBI 7 Gy in one fraction, with reduction of the lung dose to 6 Gy in one fraction by partial shielding. The majority of patients (n = 41) were males with prostate cancers (93......%). Outcome and side effects were measured by the EORTC Quality of Life Questionnaire C30 (QLQ-C30), and by the doctors' toxicity scores in the medical record. Pain relief was defined as a reduction of more than 10 points on the QLQ-C30 scale. Evaluations were performed before and 2, 4, 8, 16, and 24 weeks...

    To evaluate, in an exploratory analysis, the effect of zoledronic acid (ZOL) on skeletal-related event (SRE) incidence as determined by the bone pain levels at study entry. Bone metastases can undermine skeletal integrity long before the onset of symptoms. Treating patients before symptom onset might be more effective in preventing SREs and improving patients' quality of life. ZOL has shown significant reductions in SREs and pain compared with placebo in patients with bone metastases from advanced prostate cancer in a randomized placebo-controlled trial. Patients from a placebo-controlled, Phase III trial of men with castration-resistant prostate cancer, randomized to receive ZOL 4 mg (n = 214) or placebo (n = 208) for ≤ 24 months, were stratified by pain or no pain at baseline. Bone pain was assessed at baseline, week 3, and week 6 and at 6-week intervals thereafter. The primary endpoint was the proportion of patients with ≥ 1 SRE. ZOL significantly reduced the mean pain scores compared with placebo at 3, 9, 21, and 24 months (P ≤ .03 for each point) and reduced the annual incidence of SREs. Among patients without baseline pain, ZOL decreased the percentage of patients with ≥ 1 SRE by 39% and reduced the annual incidence of SREs by 49% compared with placebo. ZOL delayed the onset of bone pain in those patients without pain at baseline compared with placebo. ZOL reduced bone pain and SREs compared with placebo in patients with bone metastases from castration-resistant prostate cancer, irrespective of the baseline pain status, and appeared more efficacious when initiated before the onset of pain.

    Approximately 30% of patients with renal cell carcinoma (RCC) and 40% of patients with bladder cancer develop bone metastases that can disrupt normal bone homeostasis and place patients at risk for potentially life-limiting skeletal-related events (SREs). In the absence of bone-directed therapies, patients with RCC may experience up to four SREs per year. In patients with bone metastases from RCC or bladder cancer, zoledronic acid (ZOL) significantly reduced the risk of SREs compared with placebo. In addition to its bone-protective effects, preclinical and early clinical evidence indicates that ZOL prevents tumor progression. For example, retrospective subset analysis in patients with RCC indicated that ZOL extended time to disease progression and demonstrated a trend toward improved overall survival compared with placebo. Additionally, a study in patients with bone metastases from bladder cancer demonstrated that ZOL improved 1-year overall survival compared with placebo. Bone metastases place a heavy burden on patients with RCC or bladder cancer, and early, continuous treatment with ZOL may provide anticancer benefits in addition to important patient quality of life. 2010.

    Anaplastic thyroid carcinoma (ATC), an aggressive form of thyroid cancer, represents less than 2% of all thyroid cancers. The survival of patients with ATC remains low especially when accompanied with bone metastasis. This study aims to establish a reproducible animal model of bone metastasis of ATC which may be useful for further research on novel treatment strategy. Eight 6-8 week old female athymic nude mice were randomly selected. ATC cell line ARO cells were injected into the left ventricular cavity of each mouse respectively. Each mouse was imaged using a dedicated small-animal PET/CT scanner after successful injection of [18F]-FDG under deep anesthesia. Pathological examination was carried out to confirm the bone metastases of ATC. Histopathology established ATC bone metastases in five nude mice’s tibia. Similarly, PET image displayed significantly increased radioactivity (P<0.01) in the established bone metastasis compared with the control normal tibia. Both micro-PET/CT and histomorphometric measurement confirmed the bone metastases model of ATC in nude mice by left ventricular cavity injection of ARO cell line. The bone metastases model of ATC will thus facilitate the understanding of its pathogenesis and aid in the development of novel therapies.

    Breast cancer is considered to often involve bone metastasis. Early detection and treatment of bone metastasis are essential in improving the prognosis of this disease. In 47 patients with bone metastasis confirmed with bone scintigraphy, we examined the appearance time of bone metastasis; bone metastasis was frequently observed with the progress of stage, but no association with the appearance time was found. Age was not associated with the incidence of bone metastasis but was found to be closely related to its appearance time. That is to say, patients with breast cancer below 40 years of age showed relatively early bone metastasis. Bone scintigraphy is required every 6 months at least for 3 years after the operation. In patients over 40 years of age, on the other hand, bone scintigraphy is required only once a year but has to be continued for 5 years or more, because they often show relatively late bone metastasis.

    It is studied the incidence of osseus metastases and the usefulness of 179 bone scanning realized in the diagnosis and follow-up (average: 23,6 months) of 87 patients operated by breast cancer. It is obvious the scan sensitivity and its unspecificity (15,08% phase-positives). In 13 (14,9%) patients who showed them, during the follow-up, scan was pathological at the moment of the osseus metastases diagnosis or a bit later; there were other clinical data or abnormal analytical ones of suspicion in 77% of them. The time average of appearance is 27 months after surgery. We concluded that the bone scan in the follow-up of breast cancer will be realized only when clinical or analytical suspicion of bone metastases. (Author)

    Full text: Introduction: A number of studies have demonstrated the value of performing spinal SPECT in addition to planar scintigraphy for the diagnosis of bone metastases. This has however not been demonstrated in an African population where patients frequently present with more advanced disease. The aim of this study was to investigate the contribution of spinal SPECT to the diagnosis of bone metastases in an African population. Materials and methods: In a retrospective study of 576 patients with known primary tumours who underwent skeletal scintigraphy for the diagnosis of bone metastases, the students of 119 patients who underwent planar imaging and SPECT were reviewed. Blinded to the SPECT study, the planar studies were graded for the probability of metastatic disease using a four-point scale, and the number of spinal lesions was noted. This was repeated with the planar and SPECT studies reviewed together. The interpretation using the planar images alone was compared with that obtained after the addition of SPECT using non-parametric tests. Results: Of the 576 patients, 119 (45 men and 74 women) underwent planar and SPECT imaging. A wide variety of primary malignancies were presented but the majority consisted of breast carcinoma (n=55) and prostate carcinoma (n=29). The addition of SPECT resulted in a significant change in the interpretation of these studies (p<0.05), with a significantly lower proportion of patients having equivocal gradings (p<0.01). However the actual number of patients affected was relatively small (n=35) representing about 6% of the total of 576 patients. The addition of SPECT also resulted in the detection of significantly more spinal lesions (p<0.01 ). Conclusion: The addition of SPECT resulted in a statistically significant change in the interpretation of the studies, demonstrating the value of spinal SPECT in this population. However compared to the total patient population the actual number of patients affected was relatively small

    Bone scintigraphy plays a major role in the diagnosis of bone metastases. The clinical utility of new biochemical markers of bone metabolism has recently been investigated in various bone diseases. This study evaluated the role of some bone metabolism markers in comparison with bone scan in the follow-up of breast cancer patients. We studied 149 patients with breast cancer, 33 (22%) of whom had bone metastases. IRMAs were used for the evaluation of blood levels of osteocalcin, bone alkaline phosphatase (BAP), the C-terminal propeptide of type I procollagen and the C-terminal cross-linked telopeptide of type I collagen (ICTP). Multivariate regression analysis showed that menopausal status (P=0.007) and metastatic bone lesions (P=0.001) affected bone marker levels. When considering post-menopausal women, the only subset in which bone metabolism marker behaviour could be reliably investigated, we found a high degree of overlap in marker distribution for scan-positive and scan-negative patients. Discrimination between scan-negative and scan-positive patients based on the above markers, taken singly or jointly, was assessed by means of logistic discriminant analysis. The best discrimination was achieved with BAP, closely followed by ICTP. BAP and ICTP together gave a slight improvement over the use of the two markers separately. However, even in this case the degree of discrimination was poor and its clinical utility was limited. In fact, to achieve a specificity of 95%, the sensitivity of the test was about 20%; conversely, with a sensitivity of 95%, the specificity was below 10%. In conclusion, based on our findings, we believe that blood levels of the investigated markers cannot replace bone scintigraphy in the follow-up of breast cancer patients for the early detection of bone metastases.

    Full Text Available Abstract Background To estimate the costs (paid amounts of palliative radiation episodes of care (REOCs to the bone for patients with bone metastases secondary to breast or prostate cancer. Methods Claims-linked medical records from patients at 98 cancer treatment centers in 16 US states were analyzed. Inclusion criteria included a primary neoplasm of breast or prostate cancer with a secondary neoplasm of bone metastases; ≥2 visits to ≥1 radiation center during the study period (1 July 2008 through 31 December 2009 on or after the metastatic cancer diagnosis date; radiation therapy to ≥1 bone site; and ≥1 complete REOC as evidenced by a >30-day gap pre- and post-radiation therapy. Results The total number of REOCs was 220 for 207 breast cancer patients and 233 for 213 prostate cancer patients. In the main analysis (which excluded records with unpopulated costs the median number of fractions per a REOC for treatment of metastases was 10. Mean total radiation costs (i.e., radiation direct cost + cost of radiation-related procedures and visits per REOC were $7457 for patients with breast cancer and $7553 for patients with prostate cancer. Results were consistent in sensitivity analyses excluding patients with unpopulated costs. Conclusions In the US, current use of radiation therapy for bone metastases is relatively costly and the use of multi-fraction schedules remains prevalent.

    Bone metastasis is an important factor for the treatment and prognosis of breast cancer patients. Whole body bone scintigraphy (WBBS) can evaluate skeletal metastases, and 18 F FDG PET/CT seems to exhibit high specificity and accuracy in detecting bone metastases. However, there is a limitation of 18 F FDG PET in assessing sclerotic bone metastases because some lesions may be undetectable. Recent studies showed that 18 F fluoride PET/CT is more sensitive than WBBS in detecting bone metastases. This study aims to evaluate the usefulness of 18 F fluoride PET/CT by comparing it with WBBS and 18 F FDG PET/CT in breast cancer patients with osteosclerotic skeletal metastases. Nine breast cancer patients with suspected bone metastases (9 females; mean age ± SD, 55.6±10.0 years) underwent 99m Tc MDP WBBS, 18 F FDG PET/CT and 18 F fluoride PET/CT. Lesion based analysis of five regions of the skeletons(skull, vertebral column, thoracic cage, pelvic bones and long bones of extremities) and patient based analysis were performed. 18 F fluoride PET/CT, 18 F FDG PET/CT and WBBS detected 49, 20 and 25 true metastases, respectively. Sensitivity, specificity, positive predictive value and negative predictive value of 18 F fluoride PET/CT were 94.2%, 46.3%, 57.7% and 91.2%, respectively. Most true metastatic lesions of 18 F fluoride PET/CT had osteosclerotic change (45/49, 91.8%), and only four lesions showed osteolytic change. Most lesions on 18 F FDG PET/CT also demonstrated osteosclerotic change (17/20, 85.0%) with three osteolytic lesions. All true metastatic lesions detected on WBBS and 18 F FDG PET/CT were identified on 18 F fluoride PET/CT. 18 F FDG PET/CT in detecting osteosclerotic metastatic lesions. 18 F fluoride PET/CT might be useful in evaluating osteosclerotic metastases in breast cancer patients

    Full text: This research analyses the evaluation of the absorbed dose in the bone marrow for developing a calculation formalism, based on MIRD methodology, to take into account the influence of bone metastases in patients treated with 131 INa due to thyroid differentiated cancer (DTC). A methodology of image processing is stated for later quantification purposes. The dose contribution, mainly electronic, from trabecular bone and cortical bone to red marrow is considered and a general equation is developed to add that contribution. The biodistribution of active bone marrow in adults bone regions is considered from different studies (Cristy (1981), ICRP 70 (1995), Bouchet et al. (2000), ICRP 89 (2004)). It is assumed that the 60% of red marrow is in the axial skeleton, 25% in ribs, femoral head, proximal portion of chimney and breast bone, and 10% in skull and scapula. Accordingly to this distribution, the bone regions with more percentage are included to calculate the influence in the red marrow absorbed dose. The absorbed dose in bone marrow is calculated considering 4 sources: bone marrow, bone tissue with metastases, rest of the bone tissue without metastases and rest of soft tissue. Conversion factors for fifteen regions of the skeleton, obtained from Eckerman Monte Carlo simulations, were used to calculate absorbed dose in each region of bone. The absorbed dose from this formalism is based on specific biokinetic data from patients and dosimetric models. It was considered of interest to compare the results with the biological dosimetry in parallel. From this biological method, the accumulated absorbed dose from previous therapies and also the bone marrow absorbed dose due to the last radioiodine treatment can be obtained in order to compare dose assessment results between the developed formalism and biological dosimetry. The results obtained with the proposed formalism, show that lesions in some bones regions contribute more to the absorbed dose than lesions in

    Accurate staging of lung cancer is essential for effective patient management and selection of appropriate therapeutic strategy. The aim of this paper was to compare the value of bone scintigraphy and FDG PET-CT for detecting bone metastases in lung cancer patients and the impact of these modalities in disease staging. One hundred sixty-four lung cancer patients who had undergone both FDG PET-CT and bone scintigraphy within 14 days were included into this study. The analysis of FDG PET-CT and bone scintigraphy was carried out patient- and lesion-based. One hundred twenty-one patients were negative and 43 patients positive for bone metastases. FDG PET-CT found bone metastases in 42/43 patients and bone scintigraphy in 38/43 patients. Sensitivity, specificity and accuracy of FDG PET-CT and bone scintigraphy for detecting bone metastases were 97.7%, 100% and 99.4%, and 87.8%, 97.5% and 94.2%, respectively. FDG PET-CT identified 430 bone metastases and bone scintigraphy 246 bone metastases. Skull was the only region where bone scintigraphy identified more lesions than FDG PET-CT. Based on both scintigraphic modalities disagreement concerning disease stage was found in 3 patients. In conclusion, FDG PET-CT yielded a higher sensitivity, specificity and accuracy than bone scintigraphy for identifying bone metastases in lung cancer patients. FDG PET-CT thus can be recommended for initial staging of lung cancer patients without applying bone scintigraphy for the detection of bone metastases.

    The skeletal metastatic disease is a real clinical problem. Approximately 70% of patients with prostate or breast cancer and 35% of those with advanced lung, thyroid, and kidney cancers will develop skeletal metastases, which cause considerable morbidity. Several options are available for treatment, to be used either alone or in various combinations: hormones in case of hormone-sensitive tumours, chemotherapy, biphosphonates, external beam radiation therapy, surgery (in pathologic or impending fracture), bone-seeking radiopharmceuticals, and also molecular therapies. Focusing our attention to patients with prostate cancer, 50% of patients with bone metastases develop skeletal related events (SREs) such as: severe pain, pathologic fractures, spinal compression syndrome, malignant hypercalcemia, bone marrow suppression. All these SREs require adequate therapy since generally determine several functional impairments and worsen the prognosis. It is well known that skeletal complications reduce the quality of life affecting different aspects, physical, functional end emotional. SREs are associated also with lower survival

    In 21 patients with "spontaneous" knee pain, 99mTc-MDP bone scan was found to be more sensitive than clinical and radiographic examination in detecting alterations of the joint components. These alterations were shown by increased radionuclide uptake in the compartments where pain was present, which was most commonly the medial femorotibial compartment, although the femoropatellar compartment was also frequently affected. The authors conclude that bone scan should be the first imaging study performed on the knee in order to establish if further tests are necessary.

    Purpose: Throughout the years, the palliative treatment of bone metastases using bone seeking radiotracers has been part of the therapeutic resources used in oncology, but the choice of which bone seeking agent to use is not consensual across sites and limited data are available comparing the characteristics of each radioisotope. Computational simulation is a simple and practical method to study and to compare a variety of radioisotopes for different medical applications, including the palliative treatment of bone metastases. This study aims to evaluate and compare 11 different radioisotopes currently in use or under research for the palliative treatment of bone metastases using computational methods. Methods: Computational models were used to estimate the percentage of deoxyribonucleic acid (DNA) damage (fast Monte Carlo damage algorithm), the probability of correct DNA repair (Monte Carlo excision repair algorithm), and the radiation-induced cellular effects (virtual cell radiobiology algorithm) post-irradiation with selected particles emitted by phosphorus-32 ({sup 32}P), strontium-89 ({sup 89}Sr), yttrium-90 ({sup 90}Y ), tin-117 ({sup 117m}Sn), samarium-153 ({sup 153}Sm), holmium-166 ({sup 166}Ho), thulium-170 ({sup 170}Tm), lutetium-177 ({sup 177}Lu), rhenium-186 ({sup 186}Re), rhenium-188 ({sup 188}Re), and radium-223 ({sup 223}Ra). Results: {sup 223}Ra alpha particles, {sup 177}Lu beta minus particles, and {sup 170}Tm beta minus particles induced the highest cell death of all investigated particles and radioisotopes. The cell survival fraction measured post-irradiation with beta minus particles emitted by {sup 89}Sr and {sup 153}Sm, two of the most frequently used radionuclides in the palliative treatment of bone metastases in clinical routine practice, was higher than {sup 177}Lu beta minus particles and {sup 223}Ra alpha particles.

    Bone scintigraphy, by its ease of application and the use of short-lived isotopes, has revolutionised the conditions of bone metastase diagnosis. Scintigraphy possesses two advantages, the possibility it offers of exploring the whole skeleton at once and its extreme simplicity. This technique should therefore find its place at the very beginning of the bone examination, an attitude which also has dosimetric repercussions: a 'whole skeleton' examination delivers 170 mrad to the marrow, whereas spinal and pelvic X-rays deliver 325 mrad. Unfortunately the sup(99m)Tc-labelled sodium pyrophosphate bone scintigraphy is not specific to any given lesion. Diagnosis can only be improved by the appearance of tracers taken up specifically on the neoplasic tissue, as is already the case of 131 I for thyroid cancer metastases. Labelled bleomycine and 67 Ga have so far given disappointing results [fr

    Early diagnosis of recurrence after treatment of cervical cancer has large influence on the prognosis. Local recurrence can be easily discovered by speculum inspection and palpation and also by association with cytodiagnosis and colposcopy. However, remote metastases, especially bone metastasis, though not highly frequent, have been difficult to diagnose. Therefore, we attempted the combination of computerized tomography and bone scintigraphy using sup(99m)Tc-labeled phosphate in 79 cases treated for cervical cancer at stage I to III. As a result, bone metastases was found in 16.7% of the 79 patients. Out of these 79 cases, bone metastases was considered as positive by bone scintigraphy in 15 cases (20.0%), as false positive in 9 cases (11.4%) and as negative, in 55 cases (69.6%). In 24 cases consisting of 15 positive and 9 false-negative cases of bone scintigraphy, CT was performed; 13 cases were proved positive and 11 cases, negative. Thirteen cases, proved positive by both bone scintigraphy and CT were diagnosed to surely have bone metastases. Metastases was found most frequently in the vertebral column (42.1%), and the ribs (26.3%). It was found also in the pelvis and in the femur in some cases. In the cases confirmed in operation to have metastases into the lymphatic glands, the incidence of bone metastases was higher (22.5%) than in the cases without. Metastases were discovered in many cases within 1 year after operation. From the above results, it was found that bone scintigraphy was useful for early discovery of bone metastases after treatment of cervical cancer, and that the additional application with CT would be very valuable in raising the success rate for discovery.

    Purpose: To update the international consensus on palliative radiotherapy endpoints for future clinical trials in bone metastases by surveying international experts regarding previous uncertainties within the 2002 consensus, changes that may be necessary based on practice pattern changes and research findings since that time. Methods and Materials: A two-phase survey was used to determine revisions and new additions to the 2002 consensus. A total of 49 experts from the American Society for Radiation Oncology, the European Society for Therapeutic Radiology and Oncology, the Faculty of Radiation Oncology of the Royal Australian and New Zealand College of Radiologists, and the Canadian Association of Radiation Oncology who are directly involved in the care of patients with bone metastases participated in this survey. Results: Consensus was established in areas involving response definitions, eligibility criteria for future trials, reirradiation, changes in systemic therapy, radiation techniques, parameters at follow-up, and timing of assessments. Conclusion: An outline for trials in bone metastases was updated based on survey and consensus. Investigators leading trials in bone metastases are encouraged to adopt the revised guideline to promote consistent reporting. Areas for future research were identified. It is intended for the consensus to be re-examined in the future on a regular basis.

    To determine the E-cadherin and beta-catenin expression phenotype in untreated primary prostate cancer and corresponding bone metastases. Paired bone metastasis and primary prostate specimens were obtained from 14 men with untreated metastatic prostate carcinoma. The tumours were histologically graded by an independent pathologist. Expression of mRNA for E-cadherin and beta-catenin was detected within the tumour cells using in-situ hybridization with a 35S-labelled cDNA probe. The expression of E-cadherin and beta-catenin were graded as uniform, heterogeneous or negative. The mRNA for E-cadherin was expressed in 13 of 14 primary carcinomas and 11 bone metastases; beta-catenin was expressed by 13 and nine, respectively. Of the primary tumours, nine expressed E-cadherin and beta-catenin uniformly; in contrast, all metastases had down-regulated E-cadherin and/or beta-catenin. The down-regulation of E-cadherin and beta-catenin are a feature of the metastatic phenotype, which may be a significant factor in the genesis of bone metastases. However, this does not appear to be reflected in the expression of these molecules in the primary tumours.

    To assess 18 F-fluorodeoxyglucose (FDG) uptake in bone metastases in patients with and without previous treatment, and compare positive positron emission tomography (PET) with osteolytic or osteoblastic changes on computed tomography (CT). One hundred and thirty-one FDG-PET/CT studies were reviewed for bone metastases. A total of 294 lesions were found in 76 patients, 81 in untreated patients and 213 in previously treated patients. PET was assessed for abnormal FDG uptake localised by PET/CT to the skeleton. CT was evaluated for bone metastases and for blastic or lytic pattern. The relationship between the presence and pattern of bone metastases on PET and CT, and prior treatment was statistically analysed using the chi-square test. PET identified 174 (59%) metastases, while CT detected 280 (95%). FDG-avid metastases included 74/81 (91%) untreated and 100/213 (47%) treated lesions (p<0.001). On CT there were 76/81 (94%) untreated and 204/213 (96%) treated metastases (p NS). In untreated patients, 85% of lesions were seen on both PET and CT (26 blastic, 43 lytic). In treated patients, 53% of lesions were seen only on CT (95 blastic, 18 lytic). Of the osteoblastic metastases, 65/174 (37%) were PET positive and 98/120 (82%), PET negative (p<0.001). The results of the present study indicate that when imaging bone metastases, prior treatment can alter the relationship between PET and CT findings. Most untreated bone metastases are PET positive and lytic on CT, while in previously treated patients most lesions are PET negative and blastic on CT. PET and CT therefore appear to be complementary in the assessment of bone metastases. (orig.)

    Experience is presented with the diagnosis of bone metastases in patients with breast cancer using bone scintigraphy with 99m TC phosphonate and radioimmunological determination of carcinoembryonic antigen (CEA) and tissue polypeptic antigen (TPA). In a group of 395 patients, there was agreement between tumor markers (CEA, TPA) and the results of bone scintigraphy in 331 cases (84%) - negative in 193 cases (49%) and positive (i.e., in terms of bone scintigraphy results and the presence of at least one tumor marker) in 138 cases (35%). On the basis of this agreement between bone scintigraphy and CEA and TPA levels, the following algorithm is recommended in monitoring patients with breast cancer: a) follow-up of tumor markers at several month intervals and in case of an increase in their levels the patient should be referred to further examination using imaging techniques including bone scintigraphy.

    3.0 Tesla magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) was compared with combined 18F-fluorodeoxyglucose positron emission tomography and computed tomography (PET/CT) in patients with suspected bone metastases from breast cancer. A prospective clinical study was performed in 13 female breast cancer patients (mean age 61years; range 45–85 years). The spine was imaged in the sagittal plane with T1-weighted (T1), short tau inversion recovery (STIR), and T2-weighted fat-saturated (T2) sequences. The pelvis was imaged similarly in the coronal plane. Axial DWI was performed from the skull base to the mid-thigh. MRI and PET/CT were performed in all patients at a maximum interval of 10 working days and at least 14 days after chemotherapy. MRI was reviewed by two radiologists, and their consensus on potential metastases in 27 predefined locations was recorded. The predefined locations were the vertebral bodies (24), the left (1) and right (1) pelvic bones, and the sacral bone (1). The PET/CT was reviewed by a radiologists and a nuclear medicine physician. MRI detected 59 of the 60 active metastases found with our gold standard modality PET/CT. T1 had the highest sensitivity (98%) but rather low specificity (77%), but with the addition of STIR and DWI, the specificity increased to 95%. The additional metastases detected with MRI most likely represented postherapeutic residual scars without active tumour. In conclusion, 3.0 Tesla MRI with T1, STIR, and DWI is useful for the clinical evaluation of bone metastases from breast cancer and compares well to PET/CT.

    It is well recognized that colorectal cancer does not frequently metastasize to bone. The aim of this retrospective study was to establish whether colorectal cancer ever bypasses other organs and metastasizes directly to bone and whether the presence of lung lesions is superior to liver as a better predictor of the likelihood and timing of bone metastasis. We performed a retrospective analysis on patients with a clinical diagnosis of colon cancer referred for staging using whole-body 18 F-FDG PET and CT or PET/CT. We combined PET and CT reports from 252 individuals with information concerning patient history, other imaging modalities, and treatments to analyze disease progression. No patient had isolated osseous metastasis at the time of diagnosis, and none developed isolated bone metastasis without other organ involvement during our survey period. It took significantly longer for colorectal cancer patients to develop metastasis to the lungs (23.3 months) or to bone (21.2 months) than to the liver (9.8 months). Conclusion: Metastasis only to bone without other organ involvement in colorectal cancer patients is extremely rare, perhaps more rare than we previously thought. Our findings suggest that resistant metastasis to the lungs predicts potential disease progression to bone in the colorectal cancer population better than liver metastasis does

    18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET) has become widely available and an important oncological technique. To evaluate the influence of PET on detection of bone metastasis, we compared the diagnostic accuracy of PET and conventional bone scintigraphy (BS) in a variety of cancer patients. Consecutive ninety-five patients with various cancers, who received both PET and BS within one month, were retrospectively analyzed. A whole-body PET (from face to upper thigh) and a standard whole body BS were performed and these images were interpreted by two experienced nuclear medicine physicians with and without patient information using monitor diagnosis. Each image interpretation was performed according to 8 separate areas (skull, vertebra, upper limbs, sternum and clavicles, scapula, ribs, pelvis, and lower limbs) using a 5-point-scale (0: definitely negative, 1: probably negative, 2: equivocal, 3: probably positive, 4: definitely positive for bone metastasis). Twenty-one of 95 patients (22.1%) with 43 of 760 areas (5.7%) of bone metastases were finally confirmed. In untreated patients, 12 of 14 bone metastasis positive patients were detected by PET, while 9 of 14 were detected by BS. Three cases showed true positive in PET and false negative in BS due to osteolytic type bone metastases. In untreated cases, PET with and without clinical information showed better sensitivity than BS in patient-based diagnosis. For the purpose of treatment effect evaluation, PET showed better results because of its ability in the evaluation of rapid response of tumor cells to chemotherapy. Out of 10 cases of multiple-area metastases, 9 cases included vertebrae. There was only one solitary lesion located outside of field of view (FOV) of PET scan in the femur, but with clinical information that was no problem for PET diagnosis. Diagnostic accuracy of bone metastasis was comparable in PET and BS in the present study. In a usual clinical condition, limited FOV (from

    Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patients (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.

    Extra-hepatic spread is present in 5% to 15% of patients with hepatocellular carcinoma (HCC) at the time of diagnosis. The most frequent sites are lung and regional lymph nodes. Here, we report 3 cases of unsuspected HCC with symptoms due to bone lesions as initial presentation. Morphological characteristics and immunohistochemistry from the examined bone were the key data for diagnosis. None of the patients had an already known chronic liver disease. Differential diagnoses with HCC upon ectopic liver disease or hepatoid adenocarcinoma were shown. Therapy with the orally active multikinase inhibitor sorafenib plus symptomatic treatment was indicated.

    1976-01-01

    A review of the literature of 2,155 reported patients with primary carcinoma of the pancreas, revealed 110 cases or 5 percent to have skeletal metastasis by radiographic or autopsy study. A study conducted over a 2 year period disclosed that 1 case of skeletal metastasis was detected by bone scanning in 16 patients with pancreatic carcinoma. This indicates a minimum skeletal metastasis rate of 6 percent. We feel these percentages are low and can be further defined by the more routine employment of the bone scan to evaluate patients with carcinoma of the pancreas. The true figure may be much higher, perhaps as high as 20 percent.

    For many years it has been known that the sensitivity of bone scanning to the presence of destructive bony lesions favors its use in screning for bone metastases and osteomyelitis. More recently bone scanning has been routinely employed in evaluating benign skeletal pathology that may be the cause of low back pain. Bone scanning can play an important part identifying the cause of pain, clarifying the significance of radiographic findings, and evaluating the results of spinal surgery. This expansion of the role of nuclear medicine in diagnosing and managing low back pain is based in part upon novel diagnostic applications of 99m Tc-methylene diphosphonate, a radiopharmaceutical that has been available for over 15 years. Equally important for this development, however, has been the recent availability of SPECT, a tomographic imaging technique that can be used to display the spine in a series of 6- to 8-mm thick sections. Slightly more than one-half of newly purchased gamma cameras are rotating systems suitable for bone SPECT studies. Thus, many community hospitals can now perform state-of-the-art bone scans for low back pain. (orig.)

    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.

  1. Osteoprotegerin in bone metastases: mathematical solution to the puzzle.

    Directory of Open Access Journals (Sweden)

    Marc D Ryser

    Full Text Available Bone is a common site for cancer metastasis. To create space for their growth, cancer cells stimulate bone resorbing osteoclasts. Cytokine RANKL is a key osteoclast activator, while osteoprotegerin (OPG is a RANKL decoy receptor and an inhibitor of osteoclastogenesis. Consistently, systemic application of OPG decreases metastatic tumor burden in bone. However, OPG produced locally by cancer cells was shown to enhance osteolysis and tumor growth. We propose that OPG produced by cancer cells causes a local reduction in RANKL levels, inducing a steeper RANKL gradient away from the tumor and towards the bone tissue, resulting in faster resorption and tumor expansion. We tested this hypothesis using a mathematical model of nonlinear partial differential equations describing the spatial dynamics of OPG, RANKL, PTHrP, osteoclasts, tumor and bone mass. We demonstrate that at lower expression rates, tumor-derived OPG enhances the chemotactic RANKL gradient and osteolysis, whereas at higher expression rates OPG broadly inhibits RANKL and decreases osteolysis and tumor burden. Moreover, tumor expression of a soluble mediator inducing RANKL in the host tissue, such as PTHrP, is important for correct orientation of the RANKL gradient. A meta-analysis of OPG, RANKL and PTHrP expression in normal prostate, carcinoma and metastatic tissues demonstrated an increase in expression of OPG, but not RANKL, in metastatic prostate cancer, and positive correlation between OPG and PTHrP in metastatic prostate cancer. The proposed mechanism highlights the importance of the spatial distribution of receptors, decoys and ligands, and can be applied to other systems involving regulation of spatially anisotropic processes.

  2. The mechanism of uptake of bone-seeking isotopes by skeletal metastases

    Although skeletal scintigraphy has become accepted as an extremely useful method of examining the skeleton, particularly for the early detection of skeletal metastases and the assessment of their response to therapy, the underlying pathological changes which allow this use of isotopes are not well understood. This study was undertaken in man and in the experimental animal in an attempt to explain the underlying mechanism for skeletal scintigraphy. Autopsy specimens indicated that tumour invasion of bone, with the possible exception of lymphomata, is associated with a significant increase in new bone production, shown by an increase in the amount of osteoid tissue and particularly immature woven bone. The animal experiments indicated that there are two mechanisms for this new bone formation. These different mechanisms may explain the different radiographic appearances. Irrespective of the mechanism of production, this new bone had a markedly increased avidity for bone-seeking isotopes. When the tumour was successfully irradiated the bone lost its osteoblastic reaction, and the production of immature new bone ceased as did the increased uptake of bone-seeking isotopes. Investigation of the vascularity of the lesion showed that there was an increase in small vessels in the neighbourhood of the tumour. The results of the study suggest that the uptake of isotope occurs in two phases. During the first phase, which occurs very rapidly, large amounts of isotope accumulate in the extracellular fluid following the increased vascularity. In the second slower phase, the isotope is gradually concentrated by the reactive immature new woven bone. (author)

    Objective: To evaluate the therapeutic effect of 89 Sr (a pure beta emitter) using Bremsstrahlung imaging in patients with multiple bone metastases. Methods: 89 Sr Bremsstrahlung imaging was performed 1-2 weeks after injection in 14 patients with bone metastases, using GE Camstar 3200 SPECT equipped with a medium-energy collimator. To improve resolution of imaging, authors selected suitable energy level and wide window width (a 95-100% energy window around 100 KeV). Results: Abnormal uptake was seen in all and was consistent with the results of 99m Tc-MDP imaging. According to this result, authors can realize localization, retention and metabolism of 89 Sr in body. Conclusion: Bremsstrahlung imaging is useful for clinical observation and estimating the curative effect and prognosis in pure beta emitter therapy such as 89 Sr. In addition, it can be helpful in determining dose of 89 Sr if a repeated therapy is needed

    1976-07-01

    Sixty-four women with Stage II breast cancer who had Sr85 bone scans at the time of radical mastectomy were followed for 8 years in a prospective study. Those women with positive scans had a slight, but statistically significant, increased incidence of metastic disease, particularly for metastases to bone.However, 40% of those women with positive bone scans and negative roentgenograms survived 8 years without evidence of any metastatic disease. Therefore, it has not been shown at this time that bone scans should be obtained in order to exclude bone metastasis before regional therapy for breast cancer is instituted. Also, a significant percentage of women with negative bone scans developed both bone and soft tissue metastases. As many as 30% of asymptomatic women with a history of breast cancer and positive bone scans and negative bone roentgenograms may still harbor disease in bone after 8 years.

    The aims of this retrospective analysis were to compare 68 Ga-PSMA PET findings and low-dose CT findings (120 kV, 30 mA), and to obtain semiquantitative and quantitative 68 Ga-PSMA PET data in patients with prostate cancer (PC) bone metastases. In total, 152 PET/CT scans from 140 patients were evaluated. Of these patients, 30 had previously untreated primary PC, and 110 had biochemical relapse after treatment of primary PC. All patients underwent dynamic PET/CT scanning of the pelvis and lower abdomen as well as whole-body PET/CT with 68 Ga-PSMA-11. The PET/CT scans were analysed qualitatively (visually), semiquantitatively (SUV), and quantitatively based on a two-tissue compartment model and a noncompartmental approach leading to the extraction of the fractal dimension. Differences were considered significant for p values PET-positive and CT-positive, 65 were only 68 Ga-PSMA-positive, and 10 were only CT-positive. The Yang test showed that there were significantly more 68 Ga-PSMA PET-positive lesions than CT-positive lesions. Association analysis showed that PSA plasma levels were significantly correlated with several 68 Ga-PSMA-11-associated parameters in bone metastases, including the degree of tracer uptake (SUV average and SUV max ), its transport rate from plasma to the interstitial/intracellular compartment (K 1 ), its rate of binding to the PSMA receptor and its internalization (k 3 ), its influx rate (K i ), and its distribution heterogeneity. 68 Ga-PSMA PET/CT is a useful diagnostic tool in the detection of bone metastases in PC. 68 Ga-PSMA PET visualizes more bone metastases than low-dose CT. PSA plasma levels are significantly correlated with several 68 Ga-PSMA PET parameters.

    To assess the clinical usefulness of bone scintigraphy for the osseous metastases of prostatic cancer after treatment, we attempted the correlative studies on laboratory data (TAP, PAP, ALP, and LDH) and scintigraphy. In 77 patients with prostatic cancer, bone scintigraphies were performed with sup(99m)Tc-phosphorous compounds to detect bone metastases. In 34 cases (44 %) bone metastases were detected. In 21 patients out of them, we assessed the effects of hormone and chemotherapy for bone metastases using serial bone scintigraphy. In 19 cases (24.7 %) of the bone scintigraphy showed equivocal results. Of 21 patients with bone metastases, 15 patients showed improvement on scintigram after hormone or chemotherapy. In much improved group (5 patients) and moderately improved group (5 patients), TAP and PAP levels were low and stable. On the other hand, in slightly improved group (5 patients) which showed partially effective on scintigram after treatment, serum TAP and PAP level were unstable. Some cases in the group of which the 1st scintigrams showed normal were turned to positive on scintigram, while TAP, PAP, ALP and LDH level were not elevated. Therefore, follow-up bone scintigraphies have value in evaluating the disease extent in patients with prostatic carcinoma.

    The insular carcinoma of thyroid gland is a poorly frequent neoplasm, slightly differentiated and of clinical aggressive course. The bone metastasis unique as a form of presentation in absence of regional ganglions compromise or another metastasis localization is very unusual. The local invasion, regional ganglions and metastases at a distance (lung and bone) are the usual conduct. It is of interesting to highlight the importance of the immunoreactivity for Tg (thyroglobulin) to tackle the diagnosis, like also the considerable absorption with Tc 99m -MDP, I 131 and Tc 99m -MIBI by the tissue of the metastasis [es

    Radiation-induced changes in the sacroiliac joints mimicking metastases on MR images were evaluated. Twelve patients who received radiotherapy to the pelvic region due to pelvic malignancy were included in the study. All patients had undergone external beam radiation therapy to the pelvic region, and 2 patients received supplementary internal radiation. The changes in the sacroiliac joints were evaluated. Computed-tomography-guided core bone biopsy from the bone marrow was taken from their corresponding MR sections in 5 of the patients. T1 hypointense and T2 hyperintense areas with ill-defined margins in the bone marrow adjacent to the sacroiliac joints were observed in all patients. On bone scintigraphy all the lesions demonstrated increased activity. Other radiological modalities excluded fracture, soft tissue mass, and osseous destruction. Bone biopsies demonstrated peritrabecular fibrosis and inflammatory cell infiltration. Patients receiving radiotherapy to the pelvis may demonstrate T1 hypointense/T2 hyperintense, ill-defined postradiotherapeutic benign changes in the sacroiliac joints. In the absence of any other signs of disease progression and when the imaging pattern is typical, close radiological follow-up should be sufficient to rule out metastases. (orig.)

    The aim of this study was radiographically to monitor the effect of disodium pamidronate on metastatic bone disease, using image-processing techniques. Eighteen patients with osteolytic metastases from breast cancer received an intravenous infusion of 180 mg disodium pamidronate every 4 weeks for a period of 6 months. The first session of intravenous infusions was given concurrently with external beam radiotherapy with a 6 MV linear accelerator (total dose 30 Gy in 10 fractions). Radiographs of osteolytic lesions were obtained at every session of the treatment, retaining the same settings for each modality. The analysis of the attributes of the images was based on measuring the first-order statistics of the gray-level histogram in terms of mean value (MVGLH) and energy (EGLH). The measurements showed significant differences for MVGLH and EGLH values (p<0.05, Wilcoxon test). Analytically, there was an 11.08% (95% CI=10.21, 11.93) mean reduction of EGLH and an 11.63% (95% CI=10.96, 12.29) mean increase of MVGLH of the x-ray images, before and after the combined treatment protocol. The changes in the image-processing indices were also highly correlated with the reduction of the patient's pain score. These findings indicate an important increase in bone mass and bone formation, which the radiologists found difficult to identify visually

    Objective Patients with bone metastases or lesions secondary to solid tumors or multiple myeloma often experience bone complications (skeletal-related events [SREs]-radiation to bone, pathologic fracture, surgery to bone, and spinal cord compression); however, recent data that can be used to assess the value of treatments to prevent SREs across European countries are limited. This study aimed to provide estimates of health resource utilization (HRU) and cost associated with all SRE types in Europe. HRU data were reported previously; cost data are reported herein. Methods Eligible patients from 49 centers across Austria (n = 57), the Czech Republic (n = 59), Finland (n = 60), Greece (n = 59), Portugal (n = 59), and Sweden (n = 62) had bone metastases or lesions secondary to breast, lung, or prostate cancer, or multiple myeloma, and ≥1 index SRE (a SRE preceded by a SRE-free period of ≥ 6.5 months). SRE-related costs were estimated from a payer perspective using health resource utilization data from patient charts (before and after the index SRE diagnosis). Country-specific unit costs were from 2010 and local currencies were converted to 2010 euros. Results The mean costs across countries were €7043, €5242, €11,101, and €11,509 per radiation to bone, pathologic fracture, surgery to bone, and spinal cord compression event, respectively. Purchasing power parity (PPP)-adjusted mean cost ratios were similar in most countries, with the exception of radiation to bone. Limitations The overall burden of SREs may have been under-estimated owing to home visits and evaluations outside the hospital setting not being reported here. Conclusions All SREs were associated with substantial costs. Variation in SRE-associated costs between countries was most likely driven by differences in treatment practices and unit costs.

    Bone metastases are an important clinical issue in women with breast cancer. Particularly, unstable spinal bone metastases (SBM) are a major cause of severe morbidity and reduced quality of life (QoL) due to frequent immobilization. Radiotherapy (RT) is the major treatment modality and is capable of promoting re-ossification and improving stability. Since local therapy response is excellent, survival of these patients with unstable SBM is of high clinical importance. We therefore conducted this analysis to assess survival and to determine prognostic factors for bone survival (BS) in women with breast cancer and unstable SBM. A total population of 92 women with unstable SBM from breast cancer who were treated with RT at our department between January 2000 and January 2012 was retrospectively investigated. We calculated overall survival (OS) and BS (time between first diagnosis of bone metastases until death) with the Kaplan-Meier method and assessed prognostic factors for BS with a Cox regression model. Mean age at first diagnosis of breast cancer was 60.8 years ± SD 12.4 years. OS after 1, 2 and 5 years was 84.8, 66.3 and 50 %, respectively. BS after 1, 2 and 5 years was 62.0, 33.7 and 12 %, respectively. An age > 50 years (p < .001; HR 1.036 [CI 1.015–1.057]), the presence of a single bone metastasis (p = .002; HR 0.469 [CI 0.292–0.753]) and triple negative phenotype (p < .001; HR 1.068 [CI 0.933–1.125]) were identified as independent prognostic factors for BS. Our analysis demonstrated a short survival of women with breast cancer and unstable SBM. Age, presence of a solitary SBM and triple-negative phenotype correlated with survival. Our results may have an impact on therapeutic decisions in the future and offer a rationale for future prospective investigations

    Objective: To study the clinical value of serum tumor marker determination and whole body bone scan for diagnosis of bone metastases from breast cancer. Methods: Serum tumor markers (CA15-3, CEA, TSGF)were detected with GLIA and whole body bone scan were investigated by SPECT in 124 breast cancer patients. Results: In 124 patients, 38 patients were diagnosed as positive for bone metastases with whole body bone scan. The positive predicting values of CA15-3, CEA, TSGF were 76.78%, 80% and 82.14%, and the negative predicting values of CA15-3, GEA, TSGF were 82.41%, 86.74% and 84.29% respectively. The levels of CA15-3, CEA, TSGF in patients with bone metastases were significantly higher than those in patients without metastasis and the controls (P<0.01). Conclusion: Determination of levels of serum tumor markers CA15-3, CEA, TSGF is helpful for diagnosis of bone metastases from breast cancer. Combined detection of GA15-3, CEA, TSGF could increase the sensitivity and accuracy of diagnosing bone metastases. (authors)

    To evaluate the clinical efficacy of zoledronic acid combined with chemotherapy in the management of skeletal metastasis of non-small cell lung cancer (NSCLC) and investigate the value in urine amino-terminal telopeptide of type I collagen (uNTX) and serum bone specific alkaline phosphatase (sBALP) in monitoring skeletal metastasis of NSCLC. From February, 2007 to January, 2009, 32 NSCLC patients with bone metastases received treatment with zoledronic acid at the dose of 4 mg given every 3 weeks and platinum-based chemotherapy (each cycle lasting for 3 weeks). Before and during the treatments, uNTX and sBALP were measured in these patients using ELISA and precipitation with wheat germ lectin, respectively. The patients were followed up for skeletal-related events (SREs) and status of survival. A significant decrease occurred in the pain scores and analgesic use in the patients after the therapy. SREs were not observed during the treatment. Serum creatinine and calcium levels underwent no significant variation during the treatment. Eleven patients reported 14 possible zoledronic acid-related adverse events. The concentration of uNTX and sBALP in patients with bone metastases was above the upper limit of the normal range. A positive correlation was observed between the levels of the markers and the extent of bone metastases. At the third month, uNTX and sBALP were significantly lowered, but radionuclide whole-body bone imaging showed no obvious changes. Of the 32 patients, 24 had elevated uNTX values, which became normal after the treatment in 15 patients and remained elevated in the other 9 patients. SREs occurred in these two subgroups at the rates of 53% and 89% (P=0.039), respectively. Twenty-six patients had elevated sBALP level, and 16 of them exhibited normal sBALP level after the treatment. The incidences of SREs in the patients with elevated and normal sBALP level were 50% and 90% (P=0.038), respectively. The levels of uNTX/Cr and sBALP were not correlated

    Sodium pyrophosphate was chosen for its ease of application and the quality of the images it gives. The aim of this study, in the context of breast cancer exploration, is to examine: - its reliability for the detection of bone metastases, - the correlation of its results with other factors. The first part reviews the properties of sup(99m)Tc-labelled sodium pyrophosphate and the current hypotheses on the mechanism of its bone fixation, essential for an understanding of the image formation mechanism and for the interpretation of anomalies. Part two gives an analysis of 311 examinations carried out on 223 patients, obtained by the use of a coded file and modern data processing methods. The following are dealt with in turn: - material and methods, - the results themselves and especially their reliability for the whole skeleton and for one bone at a time, - discussion and comparison with published data. Sup(99m)Tc pyrophosphate bone scintigraphy is a simple examination easy to interpret and allows the whole skeleton to be explored. Abnormal scintigraphic images are: - seldom hypofixing lacunae, - usually 'hyperfixing centres' which point to a perilesional bone reaction and depend on: vascular factors, the affinity of technetium for the immature collagen fibres of the forming bone matrix, the affinity of pyrophosphate for the bone mineral substance [fr

    This was a phase I-II nonrandomized study that explored the toxicity and response of fractionated half-body irradiation (F-HBI) in patients with multiple symptomatic osseous metastases. The patients had no premedication and received 10 Gy in 5 fractions with a dose rate of 15 cGy/min. At the Cancer Institute Hospital, 9 patients were treated by this technique (1 upper and lower F-HBI, 6 upper F-HBI, 2 lower F-HBI). All patients were female and had adenocarcinomas (8 breast and 1 lung). Adverse effects were myelosuppression, vomiting and partial alopecia. But hematologic toxicity was treated with blood transfusion or G-CSF. All toxicity was transient, and no pneumonitis nor radiation-related deaths occurred. When given as palliation, F-HBI was found to relieve pain in 80% of the patients. In 10% of the patients the pain relief was complete. The mean time to achieve pain relief in responders after F-HBI was 9 days. The pain relief was long-lasting and continued without need of reirradiation for 40% of the remaining patient's life. This treatment modality appears to be well tolerated and effective in patients with multiple symptomatic osseous metastases. The optimal indications, dose and fractionation for F-HBI should be further explored in randomized trials. (author).

    Renal cell carcinoma (RCC) is thought to respond unreliably to radiotherapy (RT). Zoledronic acid significantly reduces the risk of skeletal complications. This study investigated whether RT with zoledronic acid prolonged the time to bone-lesion progression in comparison with RT alone. Twenty-seven patients (34 lesions) with bone metastases secondary to RCC undergoing treatment with RT with or without zoledronic acid were retrospectively evaluated at two institutions between 1999 and 2009. Twelve patients were treated with RT alone from 1999 to 2008 (RT group). Fifteen patients were treated with RT and zoledronic acid from 2006 to 2009 (RT+Z group). The time to skeletal-related events and pain progression were assessed from patients' medical records. The median (range) follow-up was 26 (3-75) and 24 (3-55) months in the RT and RT+Z groups, respectively. Three patients (three lesions) in the RT+Z group had skeletal-related events (SREs). In contrast, six patients (eight lesions) in the RT group had SREs. SREs comprised pathological fractures in five, additional surgeries in three, spinal cord or cauda equine compression in two, and repeat RT in one. There was a significant difference in SRE-free survival time and duration of site-specific pain response between groups. RT combined with zoledronic acid significantly prolonged SRE-free survival and duration of pain response compared with RT alone in the treatment of osseous metastases from RCC. (author)

    We designed this study to quantify the effects of radiotherapy (RT) on bone density as a local response in spinal bone metastases of women with breast cancer and, secondly, to establish bone density as an accurate and reproducible marker for assessment of local response to RT in spinal bone metastases. We retrospectively assessed 135 osteolytic spinal metastases in 115 women with metastatic breast cancer treated at our department between January 2000 and January 2012. Primary endpoint was to compare bone density in the bone metastases before, 3 months after and 6 months after RT. Bone density was measured in Hounsfield units (HU) in computed tomography scans. We calculated mean values in HU and the standard deviation (SD) as a measurement of bone density before, 3 months and 6 months after RT. T-test was used for statistical analysis of difference in bone density as well as for univariate analysis of prognostic factors for difference in bone density 3 and 6 months after RT. Mean bone density was 194.8 HU ± SD 123.0 at baseline. Bone density increased significantly by a mean of 145.8 HU ± SD 139.4 after 3 months (p = .0001) and by 250.3 HU ± SD 147.1 after 6 months (p < .0001). Women receiving bisphosphonates showed a tendency towards higher increase in bone density in the metastases after 3 months (152.6 HU ± SD 141.9 vs. 76.0 HU ± SD 86.1; p = .069) and pathological fractures before RT were associated with a significantly higher increase in bone density after 3 months (202.3 HU ± SD 161.9 vs. 130.3 HU ± SD 129.2; p = .013). Concomitant chemotherapy (ChT) or endocrine therapy (ET), hormone receptor status, performance score, applied overall RT dose and prescription of a surgical corset did not correlate with a difference in bone density after RT. Bone density measurement in HU is a practicable and reproducible method for assessment of local RT response in osteolytic metastases in breast cancer. Our analysis demonstrated an excellent local response within

  1. Molecular Mechanisms That Contribute to Bone Marrow Pain

    Jason J. Ivanusic

    2017-09-01

    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.

    This article reports the syntheses and evaluation of 68 Ga- and 153 Sm-complexes of a new DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid)-conjugated geminal bisphosphonate, DOTA-Bn-SCN-BP, for their potential uses in the early detection of skeletal metastases by imaging and palliation of pain arising from skeletal metastases, respectively. The conjugate was synthesized in high purity following an easily adaptable three-step reaction scheme. Gallium-68- and 153 Sm-complexes were prepared in high yield (>98%) and showed excellent in vitro stability in phosphate-buffered saline (PBS) and human serum. Both the complexes showed high affinity for hydroxyapatite particles in in vitro binding study. In biodistribution studies carried out in normal Wistar rats, both the complexes exhibited rapid skeletal accumulation with almost no retention in any other major organ. The newly synthesized molecule DOTA-Bn-SCN-BP would therefore be a promising targeting ligand for the development of radiopharmaceuticals for both imaging skeletal metastases and palliation of pain arising out of it in patients with cancer when radiolabeled with 68 Ga and 153 Sm, respectively. A systematic comparative evaluation, however, showed that there was no significant improvement of skeletal accumulation of the 153 Sm-DOTA-Bn-SCN-BP complex over 153 Sm-DOTMP (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetramethylenephosphonic acid) as the later itself demonstrated optimal properties required for an agent for bone pain palliation. © 2018 John Wiley & Sons A/S.

    18 F-fluorocholine is a specific promising agent for imaging tumor cell proliferation, particularly in prostate cancer, using PET/CT. It is a beneficial tool in the early detection of marrow-based metastases because it excludes distant metastases and evaluates the response to hormone therapy. In addition, 18 F-fluorocholine has the potential to differentiate between degenerative and malignant osseous abnormalities because degenerative changes are not choline-avid; however, the agent may accumulate in recent traumatic bony lesions. On the other hand, 18 F-NaF PET/CT can indicate increased bone turnover and is generally used in the assessment of primary and secondary osseous malignancies, the evaluation of response to treatment, and the clarification of abnormalities on other imaging modalities or clinical data. 18 F-NaF PET/CT is a highly sensitive method in the evaluation of bone metastases from prostate cancer, but it has problematic specificity, mainly because of tracer accumulation in degenerative and inflammatory bone diseases. In summary, 18 F-NaF PET/CT is a highly sensitive method, but 18 F-fluorocholine PET/CT can detect early bone marrow metastases and provide greater specificity in the detection of bone metastases in patients with prostate cancer. However, the difference seems not to be significant. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    Radiotherapy (RT) for palliation of pain due to bone metastases (BM) is effective but underutilized likely due to the traditional practice of separate clinic visits for consultation, treatment planning, and RT delivery. However, recent evidence proves one RT treatment is as effective as multiple for analgesia, enabling investigation of an alternative model of RT delivery, the rapid access palliative radiotherapy program (RAPRP). Prior to the start of the program, needs assessment was performed to determine the composition of the optimal team. Screening tools were implemented to streamline holistic, multidisciplinary assessment. An advertising strategy, treatment and research protocols, and mechanisms for patient feedback were established. After RAPRP implementation, patient outcomes such as symptom relief were tracked. Eighty-six patients with painful BM were referred over the 25-week pilot. Median age was 69.9 years; 64% had prostate cancer, and median performance status was 70. Patient-rated pain was on average 6.1/10 at baseline, improving to 2.6/10 by week 4 post-RT. On average, 6.2 symptoms were reported (baseline) compared to 5.2 (week 4). Team members assessed 10-100% of patients and were successful in stabilizing or improving all symptoms in >75% contacted at week 4. One hundred percent of patients surveyed were satisfied with their experience. Early needs assessment was advantageous in determining the optimal team and methods of assessment for our 'one-stop' BM clinic. This approach was successful in improving pain and other symptoms, and the convenience of seeing multiple providers on 1 day was appreciated by the patients.

    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

    Full Text Available The skeleton is a unique structure capable of providing support for the body. Bone resorption and deposition are controlled in a tightly regulated balance between osteoblasts and osteoclasts with no net bone gain or loss. However, under conditions of disease, the balance between bone resorption and deposition is upset. Osteoblasts play an important role in bone homeostasis by depositing new bone osteoid into resorption pits. It is becoming increasingly evident that osteoblasts additionally play key roles in cancer cell dissemination to bone and subsequent metastasis. Our laboratory has evidence that when osteoblasts come into contact with disseminated breast cancer cells, the osteoblasts produce factors that initially reduce breast cancer cell proliferation, yet promote cancer cell survival in bone. Other laboratories have demonstrated that osteoblasts both directly and indirectly contribute to dormant cancer cell reactivation in bone. Moreover, we have demonstrated that osteoblasts undergo an inflammatory stress response in late stages of breast cancer, and produce inflammatory cytokines that are maintenance and survival factors for breast cancer cells and osteoclasts. Advances in understanding interactions between osteoblasts, osteoclasts, and bone metastatic cancer cells will aid in controlling and ultimately preventing cancer cell metastasis to bone.

    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.

    Time is an important factor during immobilization for radiotherapy (RT) of painful spinal bone metastases. The different RT techniques currently in use have differing impacts on medical staff requirements, treatment planning and radiation delivery. This prospective analysis aimed to evaluate time management during RT of patients with spine metastases, focusing particularly on the impact of image-guided RT (IGRT). Between 21 March 2013 and 17 June 2013, we prospectively documented the time associated with the core work procedures involving the patient during the first day of RT at three different linear accelerators (LINACs). The study included 30 patients; 10 in each of three groups. Groups 1 and 2 were treated with a single photon field in the posterior-anterior direction; group 3 received a three-dimensional conformal treatment plan. The median overall durations of one treatment session were 24 and 25.5 min for the conventional RT groups and 15 min for IGRT group. The longest single procedure was patient immobilization in group 1 (median 9.5 min), whereas this was image registration and matching in groups 2 and 3 (median duration 9.5 and 5 min, respectively). Duration of irradiation (beam-on time) was similar for all groups at 4 or 5 min. The shortest immobilization procedure was observed in group 3 with a median of 3 min, compared to 4 min in group 2 and 9.5 min in group 1. With this analysis, we have shown for the first time that addition of modern IGRT does not extend the overall treatment time for patients with painful bone metastases and can be applied as part of clinical routine in a palliative setting. The choice of treatment technique should be based upon the patient's performance status, as well as the size of the target volume and location of the metastasis. (orig.)

    To examine the value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for the detection of bone metastasis in breast cancer patients and assess whether whole body bone scan (BS) with (99m)Tc-methylene diphosphonate provides any additional information. Study group comprised 150 patients, mean age 52 years (range 27-85) with breast cancer, suspected of having bone metastases. All patients had undergone both FDG-PET/CT and BS with or without single photon emission tomography/computed tomography (SPECT/CT) within a period of 6 weeks. The final diagnosis of bone metastasis was established by histopathological findings, additional imaging, or clinical follow-up longer than 10 months. Cancer antigen 15-3 (CA15-3) and carcinoembryogenic antigen (CEA) were measured in all patients. Histologically 83%, 7% and 10% had infiltrating ductal, lobular and mixed carcinoma respectively. Confirmed bone metastases were present in 86 patients (57.3%) and absent in 64 (42.7%). Mean CA15-3 and CEA values in patients with bone metastases were 74.6ng/mL and 60.4U/mL respectively, compared to 21.3ng/mL and 3.2U/mL without metastases (p<0.001). The sensitivity of FDG-PET/CT for the detection of bone metastases was 97.6% compared to 89.5% with SPECT/CT. In 57 patients, FDG-PET/CT correctly identified additional pulmonary, hepatic, nodal and other soft tissue metastases, not detected by BS. Our findings suggest that FDG-PET/CT is superior to BS with or without SPECT/CT. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM. All rights reserved.

    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

    Full Text Available Purpose: Bone scintigraphy is the standard of reference in bone metastases in prostate cancer patients. However, new radiotracers employed in prostate-specific membrane antigen (PSMA-ligands has led to the growing importance of PET/CT as diagnostic tool. The aim of our study was to investigate the difference between bone scan and PSMA-PET/CT for the detection of bone metastases in prostate cancer. Methods: Thirty patients with bone metastases originating from prostate cancer were examined by 99mTc-MDP bone scan and 68Ga-PSMA-PET/CT within an average of 21 days. Bone scans were analyzed visually according to the number of lesions and using the software package ExiniBONE by Exini Diagnostics. PET/CT data was analyzed visually. Numbers of detected lesions were compared for the different methods for the whole patient and for different regions. In addition, results were compared to serum prostate-specific antigen (PSA, alkaline phosphatase (ALP, bone alkaline phosphatase (bALP, pro gastrin releasing peptide (pGRP and eastern cooperative oncology group (ECOG performance status. Results: In the bone scans, visual and semiautomatic lesion detection showed similar results with an average of 19.4 and 17.8 detected bone lesion per patient. However, in PSMA-PET/CT, on average double the numbers of lesions (40.0 were detected. The largest differences were found in the thorax and pelvis, which can be explained by the advantages of tomographic imaging. Bland-Altman analysis showed greater differences in patients with large numbers of bone metastases. Conclusion: No significant difference was found when using semiautomatic analysis compared to visual reading for bone scans. Fewer bone metastases were detected in bone scans than in PSMA-PET/CT. However, in none of our patients would the difference have led to clinical consequences. Therefore, it seems that for patients undergoing PSMA-PET/CT, there is no need to perform additional bone scans if the appropriate

    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

    Bisphosphonates are used to prevent the bone loss and fractures associated with osteoporosis, bone metastases, multiple myeloma, and osteogenesis 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 antiresorptive 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, postfracture cutaneous cytokine upregulation, and adaptive immune responses in this CRPS model. 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 microcomputed tomography, and bone cellular activity was evaluated by static and dynamic histomorphometry. Spinal cord Fos immunostaining was performed, and skin cytokine (tumor necrosis factor, interleukin [IL]-1, IL-6) and nerve growth factor (NGF) levels were determined by enzyme immunoassay. Skin and sciatic nerve immunoglobulin levels were determined by enzyme immunoassay. Rats with tibia fractures developed hindpaw allodynia, unweighting, warmth, and edema, increased spinal Fos expression and trabecular bone loss in the lumbar vertebra and bilateral distal femurs as measured by microcomputed tomography, 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

    The bone metastasis appeared early before the bone imaging for most of the above patients. (99)Tc(m)-MDP ((99)Tc(m) marked methylene diphosphonate) bone imaging could diagnosis the bone metastasis with highly sensitivity, but with lower specificity. The aim of this study is to explore the diagnostic value of (99)Tc(m)-MDP SPECT/CT combined SPECT/MRI Multi modality imaging for the early period atypical bone metastases. 15 to 30 mCi (99)Tc(m)-MDP was intravenously injected to the 34 malignant patients diagnosed as doubtful early bone metastases. SPECT, CT and SPECT/CT images were captured and analyzed consequently. For the patients diagnosed as early period atypical bone metastases by SPECT/CT, combining the SPECT/CT and MRI together as the SPECT/MRI integrated image. The obtained SPECT/MRI image was analyzed and compared with the pathogenic results of patients. The results indicated that 34 early period doubtful metastatic focus, including 34 SPECT positive focus, 17 focus without special changes by using CT method, 11 bone metastases focus by using SPECT/CT method, 23 doubtful bone metastases focus, 8 doubtful bone metastases focus, 14 doubtful bone metastases focus and 2 focus without clear image. Totally, SPECT/CT combined with SPECT/MRI method diagnosed 30 bone metastatic focus and 4 doubtfully metastatic focus. In conclusion, (99)Tc(m)-MDP SPECT/CT combined SPECT/MRI Multi modality imaging shows a higher diagnostic value for the early period bone metastases, which also enhances the diagnostic accuracy rate.

    Complete text of publication follows: Distant metastases are found at diagnosis or during follow-up in 10%-15% of patients with differentiated thyroid cancer. Bone is the second most commonly involved site. Patients with bone metastases, whether isolated or associated with lung metastases, have a markedly poor prognosis. Ten-year survival rates range from 13% to 21%. Given such poor prognosis, the use of {sup 131}I therapy has been questioned. However, it might well be that poor prognosis of bone metastases can be overcome if {sup 131}I therapy is delivered at an early stage, when tumor burden is small, as previously demonstrated for pulmonary metastases. A review of a large series of patients showed that only rarely were bone metastases diagnosed at an early stage. Among 109 patients with bone metastases reported by Bernier et al., only 4 had both radioiodine uptake and a negative standard radiography examination. Similarly, Durante et al. reported that only 8 of 115 patients had negative radiography findings at presentation. Prognosis may improve if bone metastases are detected earlier. In a recent study, bone metastases were first detected by {sup 131}I scanning in 8 of 16 patients, when complementary radiologic studies were negative. Six of these patients showed an excellent response to {sup 131}I therapy. Today, the nuclear medicine community is well armed for this challenge toward earlier diagnosis. Postsurgery thyroid remnant ablation is more widely used. The {sup 131}I whole body scan associated with thyroid remnant ablation after thyroidectomy has a major role in early diagnosis of functioning distant metastases at a time when complementary imaging techniques (CT, MRI, bone scanning) are often still showing negative findings. Early diagnosis of specific {sup 131}I-avid bone foci will be improved with the advent and generalization of SPECT/CT. When early diagnosis is achieved, repeated {sup 131}I therapy can be effective by targeting not only visible

    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)

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two of the most severe, rare, and life-threatening adverse reactions to medications. Their incidence is approximately two patients per million population per year. Several cases have been reported in the literature in which SJS and TEN have occurred in patients with a neoplasm undergoing radiation therapy and who are taking an anticonvulsant. We report a case of SJS-TEN that developed in a 51-year-old woman with nonresectable non-small-cell lung cancer during treatment with phenobarbital plus radiation therapy for bone metastases but in whom the irradiated areas did not exhibit the SJS skin reaction. To our knowledge, no similar cases have been reported in the literature. (author)

    Purpose of this article is to present an algorithm for detection and diagnosis of skeletal metastases, which may be applied differently in symptomatic and asymptomatic cancer patients. February to March 1999 it was randomly selected and retrospectively reviewed the clinical charts of 100 cancer patients (70 women and 30 men; mean age: 63 years, range: 55-87). All the patients had been staged according to TNM criteria and had undergone conventional radiography and bone scan; when findings were equivocal, CT and MRI had been performed too. The primary lesions responsible for bone metastases were sited in the: breast (51 cases), colon (30 cases: 17 men and 13 women), lung (7 cases: 6 men and 1 woman), stomach (4 cases: 2 men and 2 women), skin (4 cases: 3 men and 1 woman), kidney (2 men), pleura (1 woman), and finally liver (1 man). The most frequent radiographic pattern was the lytic type (52%), followed by osteosclerotic, mixed, lytic vs mixed and osteosclerotic vs lytic patterns. The patients were divided into two groups: group A patients were asymptomatic and group B patients had local symptoms and/or pain. Skeletal metastases are the most common malignant bone tumors: the spine and the pelvis are the most frequent sites of metastasis, because of the presence of high amounts of red (hematopoietic active) bone marrow. Pain is the main symptom, even though many bone metastases are asymptomatic. Pathological fractures are the most severe consequences. With the algorithm for detection and diagnosis of skeletal metastases two different diagnostic courses are available for asymptomatic and symptomatic patients. Bone scintigraphy remains the technique of choice in asymptomatic patients in whom skeletal metastases are suspected. However this technique, though very sensitive, is poorly specific, and thus a negative bone scan finding is double-checked with another physical examination: if the findings remain negative, the diagnostic workup is over. On the contrary, in

    Iliac crest bone marrow biopsy (BMB) has often been used as the gold standard for the detection of bone marrow metastases in small cell lung cancer (SCLC). However, it is likely to lead to numerous false-negative results. For this reason, we compared the results of bone scintigraphy (BS), magnetic resonance imaging (MRI), and BMB in 48 sequential patients affected with pathologically confirmed SCLC (47 were evaluable; mean age, 58.4 years). The three procedures were carried out within 1 week, no treatment being performed during this period. Whole-body scans and spot views were obtained in the anterior and posterior projections. For MRI, only the thoracolumbar spine, the sternum and the pelvis were scanned, using spin-echo T1-weighted sequences, resulting in an acquisition time of less than 45 min. Only five BMBs were rated as positive. In these cases, both BS and MRI were also positive. The other 42 biopsies were negative. Among them, in ten cases both BS and MRI were positive. In 21 cases, both BS and MRI were negative. In five cases MRI was positive while BS was negative. Finally, in six cases MRI was negative whilst BS was positive. In most cases in which either BS or MRI was positive, follow-up scans confirmed the initial findings. This study suggests that BMB is more invasive and less sensitive than BS or MRI in detecting bone metastases. MRI seems to be more sensitive than BS in detecting small spinal or pelvic metastases. Whole-body bone scintigraphy is more sensitive in detecting skull, costal or peripheral metastases. BS and MRI should be used in combination and may replace BMB in the detection of bone metastases in SCLC. (orig.)

    Purpose: To automatically detect sclerotic bone metastases in the pelvic region using dual energy computed tomography (DECT). Methods: We developed a two stage algorithm to automatically detect sclerotic bone metastases in the pelvis from DECT for patients with multiple bone metastatic lesions and with hip implants. The first stage consists of extracting the bone and marrow regions by using a support vector machine (SVM) classifier. We employed a novel representation of the DECT images using multi-material decomposition, which represents each voxel as a mixture of different physical materials (e.g. bone+water+fat). Following the extraction of bone and marrow, in the second stage, a bi -histogram equalization method was employed to enhance the contrast to reveal the bone metastases. Next, meanshift segmentation was performed to separate the voxels by their intensity levels. Finally, shape-based filtering was performed to extract the possible locations of the metastatic lesions using multiple shape criteria. We used the following shape parameters: area, eccentricity, major and minor axis, perimeter and skeleton. Results: A radiologist with several years of experience with DECT manually labeled 64 regions consisting of metastatic lesions from 10 different patients. However, the patients had many more metastasic lesions throughout the pelvis. Our method correctly identified 46 of the marked 64 regions (72%). In addition, our method also identified several other lesions, which can then be validated by the radiologist. The missed lesions were typically very large elongated regions consisting of several islands of very small (<4mm) lesions. Conclusion: We developed an algorithm to automatically detect sclerotic lesions in the pelvic region from DECT. Preliminary assessment shows that our algorithm generated lesions agreeing with the radiologist generated candidate regions. Furthermore, our method reveals additional lesions that can be inspected by the radiologist, thereby

    {sup 153}Sm-ethylene diamine tetramethylene phosphonic acid ({sup 153}Sm-EDTMP) is widely used to palliate pain from bone metastases, and is being studied for combination therapy beyond palliation. Conceptually, red marrow (RM) dosimetry allows myelotoxicity to be predicted, but the correlation is poor due to dosimetric uncertainty, individual sensitivity and biological effects from previous treatments. According to EANM guidelines, basic dosimetric procedures have been studied to improve the correlation between dosimetry and myelotoxicity in {sup 153}Sm-EDTMP therapy. RM dosimetry for 33 treatments of bone metastases from breast, prostate and lung tumours was performed prospectively (with {sup 99m}Tc-MDP) and retrospectively, acquiring whole-body scans early and late after injection. The {sup 153}Sm-EDTMP activity was calculated by prospective dosimetry based on measured skeletal uptake and full physical retention, with the RM absorbed dose not exceeding 3.8 Gy. Patient-specific RM mass was evaluated by scaling in terms of body weight (BW), lean body mass (LBM) and trabecular volume (TV) estimated from CT scans of the L2-L4 vertebrae. Correlations with toxicity were determined in a selected subgroup of 27 patients, in which a better correlation between dosimetry and myelotoxicity was expected. Skeletal uptakes of {sup 99m}Tc and {sup 153}Sm (Tc{sub %} and Sm{sub %}) were well correlated. The median Sm{sub %} was higher in prostate cancer (75.3 %) than in lung (60.5 %, p = 0.005) or breast (60.8 %, p = 0.008). PLT and WBC nadirs were not correlated with administered activity, but were weakly correlated with uncorrected RM absorbed doses, and the correlation improved after rescaling in terms of BW, LBM and TV. Most patients showed transient toxicity (grade 1-3), which completely and spontaneously recovered over a few days. Using TV, RM absorbed dose was in the range 2-5 Gy, with a median of 312 cGy for PLT in patients with toxicity and 247 cGy in those with no

    For palliative care of spinal bone metastases, stability assessment is of crucial importance. Pathological fractures, instability-related patient immobility and the extent of bone metastasis have been reported to affect patient outcome and these parameters have therefore been used for treatment stratification. We report on stability-dependent fracture and survival rates in over 300 non-small cell lung cancer (NSCLC) patients. Data from 303 patients with 868 osteolytic metastases treated with radiotherapy (RT) between 2000 and 2012 were evaluated retrospectively. In NSCLC patients with bone metastases only, the retrospective 6- and 12-month overall survival (OS) rates were 76.7 and 47.2%, respectively. In patients with additional non-bone distant metastases, these values were 60.0 and 34.0%, respectively. Survival rates were significantly lower in patients with multiple bone metastases and in those suffering pathological fractures (p=0.017). No significant impact of histological type, location of spinal lesions or treatment regime was detected. Furthermore, stability assessment revealed no influence of vertebral column stability on patient outcome (p=0.739). Our analysis demonstrated a correlation between the pathological fractures of bone lesions, the number of bone metastases, additional distant metastases and survival. The results offer a rationale for future prospective investigations. (orig.)

    Many breast cancer patients experience bone metastases and suffer skeletal complications. The present study provides evidence on the protective and therapeutic potential of betulinic acid on cancer-associated bone diseases. Betulinic acid is a naturally occurring triterpenoid with the beneficial activity to limit the progression and severity of cancer, diabetes, cardiovascular diseases, atherosclerosis, and obesity. We first investigated its effect on breast cancer cells, osteoblastic cells, and osteoclasts in the vicious cycle of osteolytic bone metastasis. Betulinic acid reduced cell viability and the production of parathyroid hormone-related protein (PTHrP), a major osteolytic factor, in MDA-MB-231 human metastatic breast cancer cells stimulated with or without tumor growth factor-β. Betulinic acid blocked an increase in the receptor activator of nuclear factor-kappa B ligand (RANKL)/osteoprotegerin ratio by downregulating RANKL protein expression in PTHrP-treated human osteoblastic cells. In addition, betulinic acid inhibited RANKL-induced osteoclastogenesis in murine bone marrow macrophages and decreased the production of resorbed area in plates with a bone biomimetic synthetic surface by suppressing the secretion of matrix metalloproteinase (MMP)-2, MMP-9, and cathepsin K in RANKL-induced osteoclasts. Furthermore, oral administration of betulinic acid inhibited bone loss in mice intra-tibially inoculated with breast cancer cells and in ovariectomized mice causing estrogen deprivation, as supported by the restored bone morphometric parameters and serum bone turnover markers. Taken together, these findings suggest that betulinic acid may have the potential to prevent bone loss in patients with bone metastases and cancer treatment-induced estrogen deficiency. - Highlights: • Betulinic acid reduced PTHrP production in human metastatic breast cancer cells. • Betulinic acid blocked RANKL/OPG ratio in PTHrP-stimulated human osteoblastic cells. • Betulinic

    A multicentre trial was organized in China as part of an international coordinated research project to study the efficacy and toxicity of single-dose samarium-153 ethylene diamine tetramethylene phosphonate (EDTMP) as a palliative treatment for painful skeletal metastases. One hundred and five patients with painful bone metastases from various primaries were treated with 153 Sm-EDTMP at a dose of 37 MBq/kg(group I) or 18.5 MBq/kg (group II). The effects were evaluated according to change in daily analgesic consumption, pain score, sum of effect product (SEP), Physician's Global Assessment (PGA), blood counts, and organ function tests conducted regularly for 16 weeks. Fifty-eight of 70 patients in group I and 30 of 35 in group II had a positive response, with SEPs of 22.29±14.47 and 20.13±13.90 respectively. Of 72 patients who had been receiving analgesics, 63 reduced their consumption. PGA showed that the Karnofsky score (KS) increased from 58.54±25.90 to 71.67±26.53, indicating improved general condition, but the difference was not significant. Among subgroups of patients, only those with breast cancer showed a significant change in the Karnofsky score after treatment. Inter-group differences were found for net change in KS between patients with lung and patients with breast cancer, and between patients with lung and patients with oesophageal cancer. Seventeen patients showed no response. No serious side-effects were noted, except for falls in the white blood cell (nadir 1.5 x 10 9 /l) and platelet (nadir 6.0 x 10 10 /l) counts in 44/105 and 34/105 cases, respectively. Ten patients had an abnormal liver function test. Response and side-effects were both independent of dose. In conclusion, 153 Sm-EDTMP provided effective palliation in 83.8% of patients with painful bone metastases; the major toxicity was temporary myelosuppression. Further studies are needed to identify better ways of determining the appropriate dose in the individual case and the efficacy of

    A 48-year-old Chinese female was referred to us regarding EGFR-mutated advanced non-small cell lung cancer, and metastasis to left scapula and vertebrae bones which caused pathological fracture at T8 and T10 thoracic vertebrae. An aggressive combined therapy with icotinib, vertebrae operation, and radioactive particle implantation and immunotherapy was proposed to prevent paraplegia, relieve pain, and control the overall and local tumor lesions. No postoperative symptoms were seen after surgery, and the pain was significantly relieved. Icotinib merited a 31-month partial response with grade 1 diarrhea as its drug-related adverse event. High dose of icotinib was administered after pelvis lesion progression for 3 months with good tolerance. Combination therapy of icotinib, surgery, and internal radiation for metastases of the vertebrae bones from non-small cell lung cancer seems to be a very promising technique both for sufficient pain relief and for local control of the tumor, vertebrae operation can be an encouraging option for patients with EFGR positive mutation and good prognosis indicator.

    Opposed-phase gradient echo (GRE) MRI at 0.5 T was compared with T1-weighted GRE MRI and bone scintigraphy regarding the detection of malignant bone marrow infiltrates of the spine and pelvis. Seventeen control patients and 41 patients with suspected skeletal metastases were studied with plain and gadolinium-enhanced MRI. In the control group only a vertebral haemangioma showed contrast enhancement, while all metastases (confirmed histologically or by follow-up) were enhancing. Opposed-phase surface coil MRI showed a significantly higher contrast-to-noise ratio of 56 metastases than T1-weighted images. In 28 patients body coil opposed-phase MRI detected more metastatic foci of the spine and pelvis than did bone scintigraphy (84 vs 56). No scintigraphically visualised lesion was missed by MRI. In conclusion, body coil gadolinium-enhanced opposed-phase GRE MRI may be applied as a screening method for skeletal metastases of the spine and pelvis at intermediate field strengths. (orig.)

    Bone is the most common site of prostate cancer (PCa) progression to a therapy-resistant, lethal phenotype. We found that blockade of fibroblast growth factor receptors (FGFRs) with the receptor tyrosine kinase inhibitor dovitinib has clinical activity in a subset of men with castration-resistant PCa and bone metastases. Our integrated analyses suggest that FGF signaling mediates a positive feedback loop between PCa cells and bone cells and that blockade of FGFR1 in osteoblasts partially mediates the antitumor activity of dovitinib by improving bone quality and by blocking PCa cell–bone cell interaction. These findings account for clinical observations such as reductions in lesion size and intensity on bone scans, lymph node size, and tumor-specific symptoms without proportional declines in prostate-specific antigen concentration. Our findings suggest that targeting FGFR has therapeutic activity in advanced PCa and provide direction for the development of therapies with FGFR inhibitors. PMID:25186177

    Bone matastases are one of the most common and serious conditions requiring radiotherapy, but there is still a considerable lack of agreement on optimal radiation schedule. We analyzed patients with symptomatic osseous matastases from lung (72 patients) and breast (63 patients) carcinoma treated by palliative radiotherapy between 1983 and 1992. In this series, the incidences of symptomatic bone metastases appearing within 2 years after the first diagnosis of the primary lesion were 96% and 36% for lung and breast carcinomas, respectively. Thirty percent of bone metastases from breast carcinoma were diagnosed more than 5 years after the first diagnosis. Thus careful follow-up must be carried out for a prolonged period. Pain relief was achieved at almost the same rate for bone metastases from lung and breast carcinomas (81% and 85%, respectively), an the rapid onset of pain relief (15 Gy or less) was obtained in about half the patients for both diseases. The rapid onset of pain relief and the lack of association between the onset of pain relief and primary tumor argued against the conventional theory that tumor shrinkage is a component of the initial response. In contrast to the fact that almost all lung carcinoma patients had very poor prognoses, one third of the breast carcinoma patients were alive more than 2 years after palliative radiotherapy. Thust, the late effects of radiation, such as radiation myelopathy, must be always considered especially in breast carcinoma patients even when it is 'just' palliative radiotherapy for bone metastases.

    Full Text Available While gastric cancer is a well established angiogenesis driven tumor, no data has been published regarding angiogenesis stimulated by mast cells (MCs positive for tryptase in bone metastases from gastric cancer patients (BMGCP. It is well established that MCs play a role in immune responses and more recently it was demonstrated that MCs have been involved in tumor angiogenesis. We analyzed infiltrating MCs and neovascularization in BMGCP diagnosed by histology. A series of 15 stage T3-4N2-3M1 (by AJCC for Gastric Cancer Staging 7th Edition BMGCP from bone biopsies were selected. Tumour tissue samples were evaluated by mean of immunohistochemistry and image analysis methods in terms of MCs density positive to tryptase (MCDPT, MCs area positive to tryptase (MCAPT, microvascular density (MVD and endothelial area (EA. A significant correlation between MCDPT, MCAPT, MVD and EA groups to each other was found by Pearson and t-test analysis (r ranged from 0.68 to 0.82; p-value ranged from 0.00 to 0.02. Our very preliminary data suggest that infiltrating MCs positive for tryptase may play a role in BMGCP angiogenesis, and could be further evaluated as a novel target of anti-angiogenic therapy.

    Patients with bone-only metastases survive longer than patients with widespread visceral disease. We analyzed the prognostic impact of different baseline parameters, such as abnormal blood tests and receptor status in patients who received local radiotherapy, in addition to contemporary systemic treatment, according to national guidelines. Retrospective uni- and multivariate analyses of 57 consecutive female patients treated in the time period 2007-2014 (median follow-up=29 months). The median age was 59 years and the median time interval from the initial diagnosis of breast cancer was 57 months. The median survival was 23 months from radiotherapy and 32 months from initial diagnosis of metastatic disease. Five-year survival rates were 13 and 21%, respectively. Survival after radiotherapy was significantly longer in patients who were prescribed higher radiation doses; 29 months after ≥30 Gy and 10 months after radiotherapy improves survival in patients with bone-only disease suitable for local therapy.

    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

    123 I-IMP and bone scintigraphy with 99m Tc-MDP were consecutively performed in patients with vertebral bone metastases from hepatocellular carcinoma and lumbar spondylosis deformans in a 7-day interval or shorter. The intensity of uptake was compared. Eighteen of the 20 metastatic lesions (90%) were classified as increased uptake areas in 123 I-IMP scintigraphy. MDP-scintigraphy disclosed 16 metastatic lesions (80%), 9 as ''hot'' lesions (56%) and 7 as ''cold'' lesions (44%). 123 I-IMP scintigraphy was negative in all 12 lesions of lumbar spondylosis deformans. Compared to MDP-scintigraphy, 123 I-IMP scintigraphy was more sensitive in detecting vertebral bone metastases of hepatocellular carcinoma with smaller rates of false-positive and false-negative findings.

    Full text: Biphosphonates (BP) are very effective in treatment of bone metastatic disease. Their renal excretion defines one of the major side effects - nephrotoxicity. Glomerular filtration rate (GFR) is a basic parameter for its early detection but clinical practice often uses only serum creatinine. Aim of our retrospective study is to assess the role of dynamic kidney scintigraphy (DKS) and the estimated during it GFR in BP-treated patients with bone metastatic disease. 61 patients (53 female, 8 male), aged 33-82, with biphosphonate-treated bone metastases from breast (n53), lung (n1) and prostate (n7) cancer were enrolled for the period 27.04.2012-14.04.2015. Overall 77 studies were made, in 13 patients more than one. GFR was assessed in 57 studies. Results were compared with serum creatinine. All patients with elevated creatinine showed low GFR and decreased renal function at DKS. With normal creatinine and decreased GFR: in 31 studies kidney function was reduced, in 14 function was normal but kidney scintigraphic appearance was disturbed- mostly as in diffuse parenchymal disease. In 5 studies GFR was normal and renal function decreased. In 3 studies both parameters were normal. Zoledronic acid was changed with denosumab in 2 patients because of worsened function and strongly reduced GFR, in one patient BP was stopped after DKS. In 3 patients the interval between BP was extended because of affected renal function. GFR is more sensitive than serum creatinine levels and changes in nephrographic curves. Dynamic kidney scintigraphy is a functional method directing clinical reaction to preserve renal function

    Full text: The experimental unit of of Centro de Medicina Nuclear of the University of Sao Paulo is working on the utilization of Sm-153-EDTMP, produced by IPEN/CNEN-SP (Brazil), for the treatment of bone pain due either inflammatory process or bone tumours spontaneously developed in dogs. The effect of the injection of the radiopharmaceutical (37 MBq/kg) were analysed by observing the animal behavior against the pain and the evolution of the clinical picture of the inflammatory process. The cases where tumours were diagnosed, bone scintigraphy was performed to follow-up the evolution of those tumours. Preliminary observations indicated that, especially in inflammatory process due to disc spondylitis, there was an improvement concerning pain and consequently a better condition of the life for those animals. Bone tumours even being more difficult to evaluate, have shown a favorable evolution concerning the reduction of pain and consequently the increase in the life span of the animals

    Background: Bone metastasis is one of the most common clinical phenomena of late stage lung cancer. A major impediment to understanding the pathogenesis of bone metastasis has been the lack of an appropriate animal and cell model. This study aims to establish human lung adenocarcinoma cell line with highly bone metastases potency with 99m Tc-MDP bone scintigraphy. Methods: The human lung adenocarcinoma cancer cells SPC-A-1 were injected into the left cardiac ventricle of NIH-Beige-Nude-XID (NIH-BNX) immunodeficient mice. The metastatic lesions of tumor-bearing mice were imaged with 99m Tc-MDP bone scintigraphy on a Siemens multi-single photon emission computed tomography. Pinhole images were acquired on a GZ-B conventional gamma camera with a self-designed pinhole collimator. The mice with bone metastasis were sacrificed under deep anesthesia, and the lesions were resected. Bone metastatic cancer cells in the resected lesions were subjected for culture and then reinoculated into the NIH-BNX mice through left cardiac ventricle. The process was repeated for eight cycles to obtain a novel cell subline SPC-A-1BM. Real-time polymerase chain reaction (PCR) was used to compare the gene expression differences in the parental and SPC-A-1BM cells. Results: The bone metastasis sites were successfully revealed by bone scintigraphy. The established bone metastasis cell line SPC-A-1BM had a high potential to metastasize in bone, including mandible, humerus, thoracic vertebra, lumbar, femur, patella, ilium and cartilage rib. The expression level of vascular endothelial growth factor gene family, Bcl-2 and cell adhesion-related genes ECM1, ESM1, AF1Q, SERPINE2 and FN1 were examined. Gene expression difference was found between parental and bone-seeking metastasis cell SPC-A-1BM, which indicates SPC-A-1BM has metastatic capacity vs. its parental cells. Conclusion: SPC-A-1BM is a bone-seeking metastasis human lung adenocarcinoma cell line. Bone scintigraphy may be used as an

    Clinical care of unstable spinal bone metastases in many centers often includes patient immobilization by means of an orthopedic corset in order to prevent pathological fractures. The aim of this retrospective analysis was to evaluate the incidence of pathological fractures after radiotherapy (RT) in patients with and without orthopedic corsets and to assess prognostic factors for pathological fractures in patients with spinal bone metastases. The incidence of pathological fractures in 915 patients with 2.195 osteolytic metastases in the thoracic and lumbar spine was evaluated retrospectively on the basis of computed tomography (CT) scans between January 2000 and January 2012 depending on prescription and wearing of patient—customized orthopedic corsets. In the corset group, 6.8 and 8.0 % in no-corset group showed pathological fractures prior to RT, no significant difference between groups was detected (p = 0.473). After 6 months, patients in the corset group showed pathological fractures in 8.6 % and in no-corset group in 9.3 % (p = 0.709). The univariate and bivariate analyses demonstrated no significant prognostic factor for incidence of pathological fractures in both groups. In this analysis, we could show for the first time in more than 900 patients, that abandoning a general corset supply in patients with spinal metastases does not significantly cause increased rates of pathological fractures. Importantly, the incidence of pathological fracture after RT was small

    18F-fluoride PET/CT exhibits high sensitivity to delineate and measure the extent of bone metastatic disease in patients with prostate cancer. 18F-fluoride PET/CT could potentially replace traditional bone scintigraphy in clinical routine and trials. However, more studies are needed to assess repeatability and biological uptake variation. The aim of this study was to perform test-retest analysis of quantitative PET-derived parameters and blood/serum bone turnover markers at the same time point. Ten patients with prostate cancer and verified bone metastases were prospectively included. All underwent two serial 18F-fluoride PET/CT at 1 h post-injection. Up to five dominant index lesions and whole-body 18F-fluoride skeletal tumour burden were recorded per patient. Lesion-based PET parameters were SUVmax, SUVmean and functional tumour volume applying a VOI with 50% threshold (FTV 50% ). The total skeletal tumour burden, total lesion 18F-fluoride (TLF), was calculated using a threshold of SUV of ≥15. Blood/serum biochemical bone turnover markers obtained at the time of each PET were PSA, ALP, S-osteocalcin, S-beta-CTx, 1CTP and BAP. A total of 47 index lesions and a range of 2-122 bone metastases per patient were evaluated. Median time between 18F-fluoride PET/CT was 7 days (range 6-8 days). Repeatability coefficients were for SUVmax 26%, SUVmean 24%, FTV 50% for index lesions 23% and total skeletal tumour burden (TLF) 35%. Biochemical bone marker repeatability coefficients were for PSA 19%, ALP 23%, S-osteocalcin 18%, S-beta-CTx 22%, 1CTP 18% and BAP 23%. Quantitative 18F-fluoride uptake and simultaneous biochemical bone markers measurements are reproducible for prostate cancer metastases and show similar magnitude in test-retest variation.

    While the skeleton is not the only organ where metastasis can occur, it is one of the preferred sites, with a significant impact in patients' quality of life. With the aim of delineating the cellular and molecular mechanisms of bone metastasis, numerous studies have been employed to identify any contributing factors that trigger cancer progression. One of the major limitations of studying cancer-bone metastasis is the multifaceted nature of the native bone environment and the lack of reliable, simple, and not expensive models that strictly mimic the biological processes occurring in vivo allowing a correct translation of results. Currently, with the growing acceptance of in vitro models as effective tools for studying cancer biology, three-dimensional (3D) models have emerged as a compromise between two-dimensional cultures of isolated cancer cells and the complexity of human cancer xenografts in immunocompromised animal hosts. This descriptive systematic literature review summarizes the current status of advanced and alternative 3D in vitro bone metastases models. We have also reviewed the strategies employed by researchers to set-up these models with special reference to recent promising developments trying to better replicate the complexity and heterogeneity of a human metastasis in situ, with an outlook at their use in medicine. All these aspects will greatly contribute to the existing knowledge on bone metastases, providing a specific link to clinical scenarios and thus making 3D in vitro bone metastasis models an attractive tool for multidisciplinary experts.

    Purpose: To evaluate the effect of a provincial practice guideline on the fractionation of palliative radiation therapy for bone metastases (PRT.B) in Ontario. Methods and Materials: The present retrospective study used electronic treatment records linked to Ontario's population-based cancer registry. Hierarchical multivariable regression analysis was used to evaluate temporal trends in the use of single fractions (SFs), controlling for patient-related factors associated with the use of SFs. Results: From 1984 to 2012, 43.9% of 161,835 courses of PRT.B were administered as SFs. The percentage of SF courses was greater for older patients (age <50 years, 39.8% vs age >80 years, 52.5%), those with a shorter life expectancy (survival >12 months, 36.9% vs < 1 month, 53.6%), and those who lived farther from a radiation therapy center (<10 km, 42.1% vs > 50 km, 47.3%). The percentage of SFs to spinal fields was lower than that to other skeletal sites (31.5% vs 57.1%). The percentage of SFs varied among the cancer centers (range, 26.0%-67.8%). These differences were all highly significant in the multivariable analysis (P<.0001). In 2004, Cancer Care Ontario released a practice guideline endorsing the use of SFs for uncomplicated bone metastases. The rate of use of SFs increased from 42.3% in the pre-guideline period (1999-2003) to 52.6% in the immediate post-guideline period (2004-2007). However, it subsequently decreased again to 44.0% (2009-2012). These temporal trends were significant after controlling for patient-related factors in the multivariable analysis (P<.0001). Large intercenter variations in the use of SFs persisted after publication of the guideline. Conclusions: The publication of an Ontario practice guideline endorsing the use of SF PRT.B was associated with only a transient increase in the use of SFs in Ontario and did little to reduce intercenter variations in fractionation.

    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.

    To describe characteristics and quality-of-life (QoL), and to define factors associated with long-term survival in a subgroup of patients with prostate cancer with M1b disease. The study was based on 915 patients from a prospective randomised multicentre trial (No. 5) by the Scandinavian Prostate Cancer Group, comparing parenteral oestrogen with total androgen blockade. Long-term survival was defined as patients having an overall survival of ≥10 years, and logistic regression models were constructed to identity clinical predictors of survival. QoL during follow-up was assessed using the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire - C30 version 1 (EORTC-C30) ratings. In all, 40 (4.4%) of the 915 men survived for >10 years. Factors significantly associated with increased likelihood of surviving for >10 years in the univariate analyses were: absence of cancer-related pain; Eastern Cooperative Oncology Group (ECOG) performance status of patients with short survival, but slowly declined over the decade. A subgroup of patients with prostate cancer with M1b disease and certain characteristics showed a positive long-term response to androgen-deprivation therapy with an acceptable QoL over a decade or more. Independent predictors of long-term survival were identified as ECOG performance status of <2, limited extent of bone metastases (Soloway score of 1), and a PSA level of <231 μg/L at the time of enrolment. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Purpose: Although the effectiveness of external beam irradiation in palliation of pain from osseous metastases is well established, the optimal fractionation schedule has not been determined. Clinical studies to date have failed to demonstrate an advantage for higher doses. To further address this issue, we conducted a pooled dose response analysis using data from published Phase III clinical trials. Methods and Materials: Complete response (CR) was used as an endpoint because it was felt to be least susceptible to inconsistencies in assessment.The biological effective dose (BED) was calculated for each schedule using the linear-quadratic model and an α/β of 10. Using SAS version 6.12, the data were fitted using a weighted linear regression, a logistic model, and the spline technique. Finally, BED was categorized, and odds ratios for each level were calculated. Results: CR was assessed early and late in 383 and 1,007 patients, respectively. Linear regression on the early-response data yielded a poor fit and a nonsignificant dose coefficient. With the late-response data, there was an excellent fit (R-square = 0.842) and a highly significant dose coefficient (p = 0.0002). Fitting early CR to a logistic model, we could not establish a significant dose response relationship. However, with the late-response data there was an excellent fit and the dose coefficient was significantly different from zero (0.017 ± 0.00524; p = 0.0012). Application of the spline technique or removal of an outlier resulted in an improved fit (p 0.048 and p = 0.0001, respectively). Using BED of < 14.4 Gy as a reference level, the odds ratios for late CR were 2.29-3.32 (BED of 19.5-51.4 Gy, respectively). Conclusion: Our results demonstrate a clear dose-response for pain relief. Further testing of high intensity regiments is warranted

    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

    Full text: Bone metastasis is the most reason of pain in prostate and mammary cancer patients. The Samarium-153-EDTMP has been showed as an alternative to the treatment of the metastasis bone pain. With the objective to evaluate the use of the Sm-153-EDTMP as a systemic therapy for the metastasis bone pain, 30 patients (19 male, 11 female, average age of 64,5 years) were studied. 19 patients with prostate cancer and 11 with mammary cancer. All the patients presented previous bone scintiscanning with multiple metastasis; interruption of the chemotherapy or radiotherapy for two or more weeks and leukocyte count higher than 2,000 leukocytes/mm 3 and platelets higher than 80,000/mm 3 . The patients were classified previously to the radioisotope therapy, as far the intensity of the pain in a scale from 0 to 10 is concerned. All the patients received 37 MBq/kg (1m Ci/kg) of weight of Sm-153-EDTMP by venous via. The evaluation 6 weeks after the therapy showed complete or partial pain relief in 22 patients (73,3%). Complete or partial pain relief has been obtained in 91,0% (10 in 11) of the patients with mammary cancer and in 62,2% (12 in 19) of the patients with prostate cancer. Transitory leukopenia (lower than 2,000 leukocytes/mm 3 ) and platelet count (lower than 80,000/mm 3 ) occurred in 33,3% of the patients. 8 patients (26,7%) did not responded to the therapy. The therapy with Samarium-153-EDTMP is a simple, safe and efficient method in the treatment of the bone pain caused by metastasis

    Full Text Available Current treatments for chronic pain, such as inflammatory pain, neuropathic pain, and cancer pain are insufficient and cause severe side effects. Mounting evidence suggests that neuroinflammation in the peripheral and central nervous system (PNS and CNS plays a pivotal role in the genesis and maintenance of chronic pain. Characteristic features of neuroinflammation in chronic pain conditions include infiltration of immune cells into the PNS [e.g., the sciatic nerve and dorsal root ganglion (DRG], activation of glial cells such as microglia and astrocytes in the CNS (spinal cord and brain, and production and secretion of pro-inflammatory cytokines and chemokines [TNF, interleukin (IL-1β, IL-6, CCL2, and CXCL1]. Recent studies suggest that bone marrow stem cells or bone marrow stromal cells (BMSCs produce powerful analgesic effects in animal models of inflammatory pain, neuropathic pain, and cancer pain. We recently demonstrated that intrathecal injection of BMSCs resulted in a long-term relief of neuropathic pain for several weeks after peripheral nerve injury. Strikingly, this analgesic effect is mediated by the anti-inflammatory cytokine transforming growth factor beta secreted from BMSCs. Additionally, BMSCs exhibit potent modulation of neuroinflammation, by inhibiting monocyte infiltration, glial activation, and cytokine/chemokine production in the DRG and spinal cord. Thus, BMSCs control chronic pain by regulation of neuroinflammation in the PNS and CNS via paracrine signaling. In this review, we discuss the similar results from different laboratories of remarkable anti-nociceptive efficacy of BMSCs in animal and clinical studies. We also discuss the mechanisms by which BMSCs control neuroinflammation and chronic pain and how these cells specifically migrate to damaged tissues.

    Objective: To evaluate the effect on survival of Samarium-153-ethylene diamine tetramethylene phosphonate (153Sm-EDTMP) in patients with nasopharyngeal carcinoma (NPC) and multiple bone metastases. Methods: From 1993 to 1999, 160 patients (127 men, 33 women; median age 35 years) presented with NPC and multiple bone metastases. Of these, 40 patients had undergone chemotherapy, and 72 palliative radiotherapy. Patients were randomly divided into four groups: Group 1 (N = 20) received analgesics (control); Groups 2, 3 and 4 (N = 80, 40, and 20, respectively) received one, two or three courses, respectively, of 153Sm-EDTMP (77.7 MBq/kg/course; course interval, 4 wk). Results: Eight patients died of non-cancer-related causes, and 24 were lost to follow-up. The median survival time for Group 1 (7.8 months) was significantly less (p < 0.05) than that of Groups 2, 3 and 4 (11.6, 13.4 and 12.8 months, respectively). Patients given 153Sm-EDTMP who had had revious external radiation survived longer (p < 0.05) than those in the other treatment groups. Conclusions: Internal radiotherapy with 153Sm-EDTMP can extend survival time in patients with nasopharyngeal carcinoma and multiple bone metastases; when combined with external radiotherapy in appropriate patients, its effect on survival time is enhanced..

    was maintained in 23 patients at the follow-up of 2-7 months. One patient with lesion of humerus re-experienced severe pain in local area of PMMA injection 27 days after the operation when he got up by using the treated arm for the support of the body weight. The condition was considered as the fracture at the cement-bone interface, and the gradual pain relief was obtained in 2 days with the external fixation of p laster for limiting the motion of the treated arm, and the complete relief maintained. There was PMMA leakage in 2 cases without corresponding clinical importance. Conclusion: The technique and treatment of percutaneous PMMA cementoplasty in osteolytic metastases of the pelvis and peripheral bone was safe and effective. Considering the incidence of the potential fracture, the external fixation formotion limitation should be given after PMMA injection to extremity lesions. (authors)

    The purpose of this study was to evaluate local control and toxicity in a group of patients treated with stereotactic body radiotherapy (SBRT) for lung metastases (LM) from bone and soft tissue sarcomas. From October 2010 to July 2014, patients with LM from sarcomas not suitable for surgery were treated with daily cone-beam computed tomography-guided SBRT. The dose administered ranged from 30 to 60 Gy in 3-8 fractions. Acute and late toxicity were scored according to Common Terminology Criteria for Adverse Events version 4.0. A total of 24 patients with 68 LM from sarcomas were treated with SBRT. The median follow-up after SBRT was 17 months (range=11-51 months). Two-year actuarial lesion local control and overall survival were 85.9% and 66.4%, respectively. No G3 or greater acute and late toxicities were observed. SBRT is a safe and effective treatment for LM from sarcoma and might be used as an alternative option in patients unfit for surgery.

    To date, no prospective comparative study of the diagnostic value of STIR versus T1-weighted (T1w) sequences at both 1.5 T and 3 T has been performed with special focus on the detectability of bone metastases. 212 oncological patients had a whole-body MRI at 1.5 T and/or at 3 T. The standard protocol comprised STIR and T1w sequences. All patients who showed typical signs of bone metastases were included in the study. Evaluation of the images was performed by the calculation of the number of metastases by three independent readers and by visual assessment on a 4-point scale. 86 patients fulfilled the inclusion criteria. The total number of metastases was significantly higher on T1w than on STIR images at both field strengths (p < 0.05). T1w revealed a sensitivity of 99.72 % (3 T) and 100.00 % (1.5 T) versus STIR with 70.99 % (3 T) and 79.34 % (1.5 T). In 53 % (38/72) of all patients, STIR detected fewer bone metastases in comparison with T1w at 3 T. At 1.5 T, STIR showed inferior results in 37.5 % (18/48) of all patients. Qualitative analysis indicated a significantly better lesion conspicuity, lesion delineation and an improved image quality on T1w compared to STIR imaging at both field strengths (p < 0.05) with similar results for T1w at 1.5 T and 3 T, but inferior results for STIR especially at 3 T. The whole-body MRI protocol for the detection of bone metastases could safely be limited to the T1w sequence in adults, especially at 3 T. There is no need for an additional STIR sequence. These initial results will have a major impact on the department's workflow if confirmed by larger studies as they will help reduce examination time and therefore save financial resources.

    A number of controlled studies have recently demonstrated the role of disodium pamidronate in the prevention of skeletal complications in patients with metastatic bone disease due to breast cancer and multiple myeloma. They have also shown that it relieves pain and is well tolerated. The aim of this open prospective study was to evaluate the acceptability of a new schedule of pamidronate infusion and to assess pain, analgesic consumption and the Karnofsky Performance Status (KPS) in patients with metastatic bone pain treated with pamidronate in association or not with chemotherapy, radiotherapy, and hormone therapy. Patients with different types of cancer and at least one painful bone metastasis were treated with two cycles of 60 mg intravenous (iv) pamidronate weekly for three consecutive doses, with a 3-week interval between the two cycles (six infusions over 7 weeks), followed by one infusion every 3 weeks for a total of 24 infusions. Two hundred patients were enrolled in the study, of whom 94 received at least the first six infusions; 25 patients received all 24 infusions. Pamidronate was well tolerated in the majority of the patients both during the first six infusions and during the whole study period. In the patients under study, pain intensity decreased compared with T0 after the first two infusions (second week of treatment). The mean equivalent daily dose of oral morphine required ranged from 21.5 to 41.5 mg/day and was low and stable during the study. For the patients who remained in the study, the KPS remained around 70 during the whole treatment period and intrasubject analysis showed a substantial stability of the KPS within each subject. A first fracture occurred within 321 days in 25% of the whole population under study. Pamidronate represents a further valid therapy to add to an already consolidated list of therapies such as radiotherapy, chemotherapy, hormone therapy and orthopaedic intervention in the pain management of patients with bone

    The aim of this study was to compare 11C-choline PET/CT and bone scintigraphy (BS) for detection of bone metastases in patients with prostate cancer. Twenty-one patients with histologically proven prostate cancer underwent 11C-choline PET/CT and BS before (n = 4) or after (n = 17) treatment. Patient-, region-, and lesion-based diagnostic performances of bone metastasis of both 11C-choline PET/CT and BS were evaluated using a five-point scale by two experienced readers. Bone metastases were present in 11 (52.4%) of 21 patients and 48 (32.7%) of 147 regions; 111 lesions were found to have bone metastases. Region-based analysis showed that the sensitivity, specificity, accuracy, and area under the receiver-operating-characteristic curves (AUC) of 11C-choline PET/CT were 97.9%, 99.0%, 98.6%, and 0.9989, respectively; those of BS were 72.9%, 99.0%, 90.5%, and 0.8386, respectively. Sensitivity, accuracy, and AUC significantly differed between the two methods (McNemar test, p = 0.0015, p = 0.0015, and p PET/CT detected 110/111 metastatic lesions (99.1%); BS detected 85 (76.6%) (p PET/BS were 100%/90.3% for the blastic type, 91.7%/8.3% for the lytic type, 100%/100% for the mixed type, and 100%/53.3% for the invisible type, respectively. Significant differences in blastic, lytic, and invisible types were observed between the two methods (p = 0.013, p = 0.0044, and p = 0.023, respectively). In conclusion, 11C-choline PET/CT had greater sensitivity and accuracy than BS for detection of bone involvement in patients with prostate cancer.

    Purpose: Identification of metastatic bone lesions is critical in prostate cancer, where treatments may be more effective in patients with fewer lesions. This study aims characterize the distribution and spread of bone lesions and create a probability map of metastatic spread in bone. Methods: Fifty-five metastatic castrate-resistant prostate cancer patients received up to 3 whole-body [F-18]NaF PET/CT scans. Lesions were identified by physician on PET/CT and contoured using a threshold of SUV>15. An atlas-based segmentation method was used to create CT regions, which determined skeletal location of lesions. Patients were divided into 3 groups with low (N<40), medium (40100) numbers of lesions. A combination of articulated and deformable registrations was used to register the skeletal segments and lesions of each patient to a single skeleton. All the lesion data was then combined to make a probability map. Results: A total of 4038 metastatic lesions (mean 74, range 2–304) were identified. Skeletal regions with highest occurrence of lesions included ribs, thoracic spine, and pelvis with 21%, 19%, and 15% of the total number lesions and 8%, 18%, and 31 % of the total lesion volume, respectively. Interestingly, patients with fewer lesions were found to have a lower proportion of lesions in the ribs (9% in low vs. 27% in high number of lesions). Additionally, the probability map showed specific areas in the spine and pelvis where over 75% of patients had metastases, and other areas in the skeleton with a less than 2% of metastases. Conclusion: We identified skeletal regions with higher incidence of metastases and specific sub-regions in the skeleton that had high or low probability of occurrence of metastases. Additionally, we found that metastatic lesions in the ribs and skull occur more commonly in advanced disease. These results may have future applications in computer-aided diagnosis.

    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

    Prostate cancer subjects with prostate-specific antigen (PSA) relapse who are treated with androgen deprivation therapy (ADT) are recommended to have baseline and serial bone densitometry and receive bisphosphonates. The purpose of this community population study was to assess the utilization of bone densitometry and bisphosphonate therapy in men receiving ADT for non-metastatic prostate cancer. A cohort study of men aged 65 years or older with non-metastatic incident diagnoses of prostate cancer was obtained from the Surveillance Epidemiology End Results (SEER)-linked Medicare claims between 2004 and 2008. Claims were used to assess prescribed treatment of ADT, bone densitometry, and bisphosphonates. A total of 30,846 incident prostate cancer cases receiving ADT and aged 65 years or older had no bone metastases; 87.3% (n=26,935) on ADT did not receive either bone densitometry or bisphosphonate therapy. Three percent (n=931) of the cases on ADT received bisphosphonate therapy without ever receiving bone densitometry, 8.8% (n=2,702) of the cases on ADT received bone densitometry without receiving intravenous bisphosphonates, while nearly 1% (0.90%, n=278) of the cases on ADT received both bone densitometry and bisphosphonates. Analysis showed treatment differed by patient characteristics. Contrary to the recommendations, bone densitometry and bisphosphonate therapy are underutilized in men receiving ADT for non-metastatic prostate cancer

    The patients receiving maintenance hemodialysis were divided into two groups in the absence and the presence of bone pain and investigated the markers of bone pain in these patients. These results suggested that the duration of receiving hemodialysis, serum contrations of alkaline phosphatase, osteocalcin and parathyroid hormone became to be the markers of bone pain. (author)

    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 trial was to compare the effects of resistance training versus passive physical therapy on quality of life (QoL), fatigue, and emotional distress outcomes during radiation therapy in patients with spinal bone metastases under radiotherapy (RT). In this randomized trial, 60 patients were treated from September 2011 until March 2013 into one of the two groups: isometric resistance training or physical therapy with thirty patients in each group during RT. EORTC QLQ-BM22, EORTC QLQ-FA13, and FBK-R10 were assessed at baseline, three months, and six months after RT. Psychosocial aspects in resistance training group (Arm A) were significantly improved after three (p = 0.001) and six months (p = 0.010). Other rated items of the QLQ-BM22 painful site, and pain characteristics were without significant differences. Functional interference showed a positive trend after six months (p = 0.081). After six months, physical fatigue (p = 0.013), and interference with daily life (p = 0.006) according to the QLQ-FA13 assessment improved in Arm A significantly. Emotional distress was in Arm A lower after six months (p = 0.016). The Cohen’s effect size confirmed the clinically significant improvement of these findings. In this group of patients we were able to show that guided isometric resistance training of the paravertebral muscles can improve functional capacity, reduce fatigue and thereby enhance QoL over a 6-months period in patients with stable spinal metastases. The results offer a rationale for future large controlled investigations to confirm these findings

  13. Doxorubicin-mediated bone loss in breast cancer bone metastases is driven by an interplay between oxidative stress and induction of TGFβ.

    Tapasi Rana

    Full Text Available Breast cancer patients, who are already at increased risk of developing bone metastases and osteolytic bone damage, are often treated with doxorubicin. Unfortunately, doxorubicin has been reported to induce damage to bone. Moreover, we have previously reported that doxorubicin treatment increases circulating levels of TGFβ in murine pre-clinical models. TGFβ has been implicated in promoting osteolytic bone damage, a consequence of increased osteoclast-mediated resorption and suppression of osteoblast differentiation. Therefore, we hypothesized that in a preclinical breast cancer bone metastasis model, administration of doxorubicin would accelerate bone loss in a TGFβ-mediated manner. Administration of doxorubicin to 4T1 tumor-bearing mice produced an eightfold increase in osteolytic lesion areas compared untreated tumor-bearing mice (P = 0.002 and an almost 50% decrease in trabecular bone volume expressed in BV/TV (P = 0.0005, both of which were rescued by anti-TGFβ antibody (1D11. Doxorubicin, which is a known inducer of oxidative stress, decreased osteoblast survival and differentiation, which was rescued by N-acetyl cysteine (NAC. Furthermore, doxorubicin treatment decreased Cu-ZnSOD (SOD1 expression and enzyme activity in vitro, and treatment with anti-TGFβ antibody was able to rescue both. In conclusion, a combination therapy using doxorubicin and anti-TGFβ antibody might be beneficial for preventing therapy-related bone loss in cancer patients.

    Full Text Available Bone scintigraphy, despite being non-specific, is a very sensitive and simple investigation for patients with active Paget’s disease of the bone. Skeletal metastases and Paget’s disease may co-exist in the elderly patients as both conditions are commonly seen in this age group. Clinical and radiological correlation may help to improve the diagnostic specificity of a bone scintigram. We report a patient in whom concurrent Paget’s disease and a rib fracture became evident only on repeat scintigraphy following successful treatment of prostate carcinoma skeletal metastases.

    Pain is a severe and debilitating complication of metastatic bone cancer. Current analgesics do not provide sufficient pain relief for all patients, creating a great need for new treatment options. The Src kinase, a non-receptor protein tyrosine kinase, is implicated in processes involved in cancer......-induced bone pain, including cancer growth, osteoclastic bone degradation and nociceptive signalling. Here we investigate the role of dasatinib, an oral Src kinase family and Bcr-Abl tyrosine kinase inhibitor, in an animal model of cancer-induced bone pain.

    2002-01-01

    Introduction: Ethilenediamine tetramethylene phosphonate (EDTMP) is a tetraphosphonate ligand which, when labeled with 188 Re, can be used for relief of metastatic bone pain. The preferential localization of phosphonate complexes in bone is attributed to their affinity for calcium, and tetraphosphonates may be equal or superior to diphosphonates in this regard. In the present study, it was aimed to determine optimal conditions for preparation of a kit of EDTMP to be labeled with 188 Re. Methods: EDTMP was dissolved in NaOH 1N, and alkalinity was reversed with HCl till pH 2, when SnCl 2 . 2H 2 0 and also ascorbic acid were introduced in the mixture, followed by Na 188 ReO 4 . The preparation was incubated in water bath for 30 minutes and after cooling radiochemical purity was assessed. Optimization of the process consisted in varying the values of EDTMP mass (20, 30, 40 mg) SnCl 2 .2H 2 0 concentration (0.5, 1.0, 2.0 and 3.0 mg/mL), and reaction time (15 and 30 minutes). Radiochemical purity and stability were ascertained in vitro and also in Swiss mice. Bone/muscle uptake ratio was calculated from %ID/g of these organs. Results: The best 188 Re-EDTMP complex was obtained with 40 mg of the ligand and 2 mg/mL of stannous chloride heated during 15 minutes, and the product was radiochemically stable during 24 hours. Kidney and bone uptake were very significant (respectively 4.5 ± 0.5% and 3.1 ± 0.3 %ID/g). Bone/muscle ratio observed four hours post-injection was also very adequate (28.5). Conclusions: A stable and biologically useful complex of 188 Re-EDTMP can be prepared with high concentration of EDTMP and considerable uptake by bone. It compares favorably with 153 Sm-EDTMP, as 188 Re has more advantageous radioisotopic properties than 153 Sm, and it can be recommended for further studies in conditions of painful bone metastases

    99m-technetium-labelled pyrophosphates are used at present. This technique combines the tropism of inorganic phosphates for the skeleton with the particularly suitable physical characteristics of technetium. The bone receives on irradiation of 0.5 rads for 10 millicuries of technetium, i.e. the equivalent of three lung X-rays, which means that the examination can safety be carried out on children. The scintigraph is performed with a two-head scanner giving a frontal image, showing in particular the shoulders, sternum, ribs and pelvic belt, and a dorsal image giving a better view of the spine and especially the sacro-iliac joints. When bone metastases are investigated by scintigraphic as compared to radiographic examination it should be remembered that 99mTc-labelled pyrophosphate scintigraphy, while revealing bone metastases at a pre-radiological stage in some cases, cannot distinguish between a benign and a malignant hyperfixing lesion nor show whether or not several lesions on the same scintigram are similar in origin. In this respect these two paraclinical examinations are complementary and give excellent results when used together [fr

    The aim of the present study was to conduct a cross-cultural adaptation (with translation into Brazilian Portuguese) and validation of the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-Bone Metastases-22 (EORTC QLQ-BM22). Ninety-five bone metastasis patients (31 men and 64 women, mean age 58.36±8.90 years) took part in the investigation. The translation guide of the EORTC was used to translate from English into Brazilian Portuguese and adapt the instrument culturally. The reliability and the face, content and construct validities were tested. Internal consistency was estimated using Cronbach's alpha for the total score, pain and functional subscales of the EORTC QLQ-BM22 (0.93, 0.86, 0.90). Reliability was analyzed by Pearson's correlation and intraclass correlation coefficients (ICCs). The correlations were higher than the recommended value of 0.75, which indicated good test-retest reliability. Construct validity was demonstrated by correlation with the questionnaire medical outcome study questionnaire 36-Item Short Form Survey (SF-36). It showed significant correlation between the fields of QLQ-BM22 and the SF-36 (P≤0.001). The EORTC QLQ-BM22 was translated into Brazilian Portuguese, was culturally adapted and was proven to be reliable, with face, content and construct validity.

    In the present work the current status of the use of Radiopharmaceuticals in the treatment of the pain provoked by bony metastasis is revised. Particular attention is devoted to the used doses, the effectiveness and security of the existent products in the market and in development. The convenience of the routine use in the case of multiple metastasis is established, since the results are adequate and the risks acceptable. The doses are examined, the adverse effects and the importance of the costs is indicated and related with it the supply of Radionuclides. Reference is made so much to the practice of countries developed as to that of countries of smaller resources. It is pointed out the Cuban experience and the perspectives of the use in our country.(author)

    Purpose: To validate imaging parameters from diffusion-weighted imaging and dynamic contrast-enhanced MRI with immunohistology and to non-invasively assess microstructure of experimental breast cancer bone metastases. Materials and methods: Animals bearing breast cancer bone metastases were imaged in a clinical 1.5 T MRI scanner. HASTE sequences were performed to calculate apparent diffusion coefficients. Saturation recovery turbo FLASH sequences were conducted while infusing 0.1 mmol/l Gd–DTPA for dynamic contrast-enhanced MRI to quantify parameters amplitude A and exchange rate constant k{sub ep}. After imaging, bone metastases were analyzed immunohistologically. Results: We found correlations of the apparent diffusion coefficients from diffusion-weighted imaging with tumor cellularity as assessed with cell nuclei staining. Histological vessel maturity was correlated negatively with parameters A and k{sub ep} from dynamic contrast-enhanced MRI. Tumor size correlated inversely with cell density and vessel permeability as well as positively with mean vessel calibers. Parameters from the rim of bone metastases differed significantly from values of the center. Conclusion: In vivo diffusion-weighted imaging and dynamic contrast-enhanced MRI in experimental bone metastases provide information about tumor cellularity and vascularity and correlate well with immunohistology.

    Bone is the most common site of prostate cancer (PCa) progression to a therapy-resistant, lethal phenotype. We found that blockade of fibroblast growth factor receptors (FGFRs) with the receptor tyrosine kinase inhibitor dovitinib has clinical activity in a subset of men with castration-resistant PCa and bone metastases. Our integrated analyses suggest that FGF signaling mediates a positive feedback loop between PCa cells and bone cells and that blockade of FGFR1 in osteoblasts partially mediates the antitumor activity of dovitinib by improving bone quality and by blocking PCa cell-bone cell interaction. These findings account for clinical observations such as reductions in lesion size and intensity on bone scans, lymph node size, and tumor-specific symptoms without proportional declines in serum prostate-specific antigen concentration. Our findings suggest that targeting FGFR has therapeutic activity in advanced PCa and provide direction for the development of therapies with FGFR inhibitors.

    The objective of this study was to determine the utility of 99m Tc-(V)- Dmsa whole body planar scan in the diagnostic of skeletal metastases. Nineteen patients were studied, having a recent 99m Tc-HDP bone scan reporting different pathologies (3 normal scans, 5 equivocal scans and 11 with disseminated bone metastases). 72 hours later, a whole body planar scan was obtained at 3 and 24 hours after the i.v. administration of 99m Tc-(V)-Dmsa. Counts per pixel were determined in regions of interest drawn over metastases sites and in normal tissue, and were correlated with the bone scan. Statistical analysis was carried out by using the Kruskal-Wallis analysis of variance followed by Mann Whitney U test. Other comparisons were done with Momios, chi square and t Student tests. 273 lesions were studied in the whole body bone scan and 184 lesions in the 99m Tc-(V)-Dmsa scintigraphy (t Student test n.s.). The tumor to normal tissue ratios were 3.3 (+/- 0.521) and the soft to normal tissue ratios were 1.01 (+/- 0.01), Mann Whitney p 99m Tc-(V)-Dmsa scintigraphy is an useful choice in the diagnostic of bone metastases when the whole body planar bone scan ( 99m Tc- HDP) is equivocal or abnormal. It also points out other lesions such as in bone and in soft tissue. (Author)

    To investigate the effects of music therapy on the pain behaviors and survival of rats with bone cancer pain and analyze the mediating mechanism of mitogen activated protein kinase (MAPK) signal transduction pathway. Male Wistar rats aged 5-8 weeks and weighing 160-200 g were collected. The rat models of colorectal cancer bone cancer pain was successfully established. Animals were divided into experimental and control group, each with 10 rats. The animals in the observation group were given Mozart K448 sonata, sound intensity of 60 db, played the sonata once every 1 hr in the daytime, stopped playing during the night, and this cycle was kept for 2 weeks. On the other hand, rats in the control group were kept under the same environment without music. Animals in the experimental group consumed more feed and gained significant weight in comparison to the control group. The tumor volume of the experimental group was significantly smaller than that of the control group (pMusic therapy may improve the pain behaviors in rats with bone cancer pain, which might be related with low expression of p38á and p38β in the MAPK signal transduction pathway.

    Purpose: Stereotactic body radiation therapy (SBRT) has been proposed for the palliation of painful vertebral bone metastases because higher radiation doses may result in superior and more durable pain control. A phase III clinical trial (Radiation Therapy Oncology Group 0631) comparing single fraction SBRT with single fraction external beam radiation therapy (EBRT) in palliative treatment of painful vertebral bone metastases is now ongoing. We performed a cost-effectiveness analysis to compare these strategies. Methods and Materials: A Markov model, using a 1-month cycle over a lifetime horizon, was developed to compare the cost-effectiveness of SBRT (16 or 18 Gy in 1 fraction) with that of 8 Gy in 1 fraction of EBRT. Transition probabilities, quality of life utilities, and costs associated with SBRT and EBRT were captured in the model. Costs were based on Medicare reimbursement in 2014. Strategies were compared using the incremental cost-effectiveness ratio (ICER), and effectiveness was measured in quality-adjusted life years (QALYs). To account for uncertainty, 1-way, 2-way and probabilistic sensitivity analyses were performed. Strategies were evaluated with a willingness-to-pay (WTP) threshold of $100,000 per QALY gained. Results: Base case pain relief after the treatment was assumed as 20% higher in SBRT. Base case treatment costs for SBRT and EBRT were $9000 and $1087, respectively. In the base case analysis, SBRT resulted in an ICER of $124,552 per QALY gained. In 1-way sensitivity analyses, results were most sensitive to variation of the utility of unrelieved pain; the utility of relieved pain after initial treatment and median survival were also sensitive to variation. If median survival is ≥11 months, SBRT cost <$100,000 per QALY gained. Conclusion: SBRT for palliation of vertebral bone metastases is not cost-effective compared with EBRT at a $100,000 per QALY gained WTP threshold. However, if median survival is ≥11 months, SBRT costs ≤$100

    Purpose: Stereotactic body radiation therapy (SBRT) has been proposed for the palliation of painful vertebral bone metastases because higher radiation doses may result in superior and more durable pain control. A phase III clinical trial (Radiation Therapy Oncology Group 0631) comparing single fraction SBRT with single fraction external beam radiation therapy (EBRT) in palliative treatment of painful vertebral bone metastases is now ongoing. We performed a cost-effectiveness analysis to compare these strategies. Methods and Materials: A Markov model, using a 1-month cycle over a lifetime horizon, was developed to compare the cost-effectiveness of SBRT (16 or 18 Gy in 1 fraction) with that of 8 Gy in 1 fraction of EBRT.

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    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

    The therapeutic effects of external beam radiation to bone or lymph-node metastatic lesions of thyroid cancer were evaluated in 11 patients. These 11 cases included four male and seven female patients ranging in age from 44 to 69 years (mean age 54 years), were treated by 4MV-Xray irradiation. Thyroid surgery had been performed in all patients. The thyroid tumors were classified histologically as papillary carcinoma in 3 patients and follicular carcinoma in 8. Following surgical total thyroidectomy, thyroid ablation and/or therapy with I-131 was performed in 8 patients with follicular carcinoma. Using a 4MV-Xray external beam, a total dose of 54 to 68 Gy (mean dose 62 Gy) was delivered to 28 metastatic lesions including 2 lymph nodes and 26 bones, although an 82-Gy total dose was used for one lymph node. All patients underwent follow-up for more than 8 years. Ten of the 11 patients died, 6 of thyroid cancer and 4 of other diseases. Two of them suffered anaplastic transformation of differentiated thyroid carcinoma and died. The survival term was 0.2 to 8.6 years (mean 4.9 years) after initial external radiotherapy. Local irradiation with a curative dose was able to control most of the lesions in the 11 patients (29 lesions with the exception of 2 cases showing anaplastic transformation). In some patients, pain relief was obtained although tumor size measured by CT did not reveal marked regression. External beam radiation therapy with a curative dose was thought to be beneficial for patients with metastatic lesions of thyroid cancer as slow-growing and having relatively long survival period of patients.

    The clinical management of patients with skeletal metastases puts new demands on imaging. The radiological imaging in screening for skeletal metastases entails detection, metastatic site description and radiologically guided biopsy for morphological typing and diagnosis. Regarding sensitivity and the ease in performing surveys of the whole skeleton, radionuclide bone scintigraphy still is the first choice in routine follow-up of asymptomatic patients with metastatic disease of the skeleton. A negative scan has to be re-evaluated with other findings, with emphasis on the possibility of a false-negative result. Screening for metastases in patients with local symptoms or pain is best accomplished by a combination of radiography and MRI. Water-weighted sequences are superior in sensitivity and in detection of metastases. Standard spin-echo sequences on the other hand are superior in metastatic site description and in detection of intraspinal metastases. MRI is helpful in differentiating between malignant disease, infection, benign vertebral collapse, insufficiency fracture after radiation therapy, degenerative vertebral disease and benign skeletal lesions. About 30% of patients with known cancer have benign causes of radiographic abnormalities. Most of these are related to degenerative diseases and are often easily diagnosed. However, due to overlap in MRI characteristics, bone biopsy sometimes is essential for differentiating between malignant and nonmalignant lesions. Performing bone biopsy and aspiration cytology by radiologist and cytologist in co-operation has proven highly accurate in diagnosing bone lesions. The procedure involves low risk to the patient and provides a morphological diagnosis. Once a suspected metastatic lesion is detected, irrespective of modality, the morphological diagnosis determines the appropriate work-up imaging with respect to the therapy alternatives. (orig./VHE)

    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.

    Strontium-89 (Sr-89) has been considered to have a tumoricidal effect with minimal adverse events. However, few reports have investigated these effects in detail. In this study, we examined the tumoricidal and pain-relief effects of Sr-89 on prostate cancer with bone metastasis as well as survival. A retrospective study was performed involving 31 prostate cancer patients with bone metastasis treated with Sr-89. Using prostate specific antigen (PSA) as an evaluation criterion of cancer control, patients were divided into PSA responder and non-responder groups, and the survival rates of these groups were compared. In addition, using the total amount of painkillers administered as an evaluation criterion of pain relief, patients were divided into pain responder and non-responder groups, and the survival rates of these groups were also compared. As secondary investigation items, age, PSA (ng/ml), pain site, extent of the disease, the presence or absence of castration-resistant prostatic cancer (CRPC), the presence or absence of a past medical history of treatment with docetaxel in CRPC cases, Gleason Score, hemoglobin (g/dl), platelet (Plt) (/μl), serum carboxyterminal telopeptide of type I collagen (ng/ml), and bone-alkaline phosphatase (BAP) (U/l) were investigated. Longer survival was expected for the PSA responder group than for the PSA non-responder group, and whether the spine was the pain site and the presence or absence of CRPC were useful as predictors of this. Plt was suggested to be a useful indicator. Furthermore, the survival time was significantly longer in the pain responder group than in the pain non-responder group, and whether the pain site was present in the spine was considered to be a predictor; however, no significant difference was noted in any of the items assumed to be biomarkers. Sr-89 has the potential to control PSA and prolong survival. A large-scale prospective study of the therapeutic effect of Sr-89 is expected. (author)

    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

    Percutaneous vertebroplasty (PV) is a therapeutic option in patients with vertebral metastases (VM). However its efficacy in pain relief, improvement in quality of life and safety in patients with VM from breast cancer has not been reported. We present a longitudinal retrospective study of 31 consecutively treated female patients with VM from breast cancer where 88 vertebrae were treated in 44 sessions of PV, in which osteolytic, osteoblastic and mixed lesions were recorded. The visual analogue pain scale (VAS) was used to evaluate pain pre-PV, at one, three, six and 12 months post-PV. The Eastern Cooperative Group (ECOG) performance status scale was used at the same time intervals to measure quality of life: 90.3% pain relief was identified with a VAS reduction from 5.7 ± 2.0 pre-PV to 2.9 ± 2.2 post-PV at one-month follow-up (ppain relief, and improvement of quality of life in patients with diverse types of VM from breast cancer.

    The objective of this study was to evaluate the feasibility and diagnostic value of 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) and 99m Tc-methylenediphosphonate (MDP) whole-body bone scanning (BS) for the detection of osteolytic bone metastases. Thirty-four patients with pathologically confirmed malignancies and suspected osteolytic bone metastases underwent 18 F-FDG PET/CT and 99m Tc-MDP whole-body BS within 30 days. The sensitivity, specificity, and accuracy with respect to the diagnosis of osteolytic bone metastases and bone lesions were compared between the two imaging methods. The sensitivity, specificity, and accuracy of 18 F-FDG PET/CT for the diagnosis of osteolytic bone metastases were 94.3% (95% confidence interval [CI], 91.6–96.2%), 83.3% (95% CI, 43.6–96.9%), and 94.2% (95% CI, 91.5–96.1%), respectively. It was found that 99m Tc-MDP whole-body BS could discriminate between patients with 50.2% (95% CI, 45.4–55.1%) sensitivity, 50.0% (95% CI, 18.8–81.2%) specificity, and 50.2% (95% CI, 45.5–55.1%) accuracy. 18 F-FDG PET/CT achieved higher sensitivity, specificity, and accuracy in detecting osteolytic bone metastases than 99mTc-MDP whole-body BS (p<0.001). F-FDG PET/CT has a higher diagnostic value than 99m Tc-MDP whole-body BS in the detection of osteolytic bone metastases, especially in the vertebra

    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

    To perform a meta-analysis comparing the diagnostic value of 18 FDG-PET, MRI, and bone scintigraphy (BS) in detecting bone metastases in patients with breast cancer. MEDLINE, EMBASE, Scopus, ScienceDirect, SpringerLink, Web of Knowledge, EBSCO, and the Cochrane Database of Systematic Review databases were searched for relevant original articles published from January 1995 to January 2010. Inclusion criteria was as follows: 18 FDG-PET, MRI or 99m Tc-MDP BS was performed to detect bone metastases (the number of published CT studies was inadequate for meta-analysis and therefore could not be included in this study); sufficient data were presented to construct a 2 x 2 contingency table; histopathological analysis and/or close clinical and imaging follow-up for at least 6 months were used as the reference standard. Two reviewers independently assessed potentially eligible studies and extracted relevant data. A software program called ''META-DiSc'' was used to obtain the pooled estimates for sensitivity, specificity, diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves, and the *Q index for each modality. Thirteen articles consisting of 23 studies fulfilled all inclusion criteria. On a per-patient basis, the pooled sensitivity estimates for MRI (97.1%) were significantly higher than those for PET (83.3%) and BS (87.0%; P 0.05). The pooled DOR estimates for MRI (298.5) were significantly higher than those for PET (82.1%) and BS (49.3%; P 0.05). The SROC curve for MRI showed better diagnostic accuracy than those for PET and BS. The SROC curve for PET was better than that for BS. The*Q index for MRI (0.935), PET (0.922), and BS (0.872) showed no significant difference (P ≥0.05). On a per-lesion basis, the pooled sensitivity estimates for BS (87.8%) were significantly higher than those for PET (52.7%; P 18 FDG-PET and BS for diagnosis of bone metastases in patients with breast cancer on a per-patient basis.

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate. Of 172 post-operative cases, 20.8% (11/53) of those with lymph node metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymph node metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.).

    Normal and metastatic bone differ in their histological structure. Normal bone is mainly lamellar while metastatic bone formation is made in a large part out of new woven bone. The woven bone has a much larger surface area than the more stable lamellar bone and it is lined with metabolically active osteoblasts. The crystalline structures in the woven bone are smaller and have a larger surface area available for absorption. Uptake of bone seeking radiopharmaceuticals continues in new woven bone longer than in the lamellar bone. Bone scintigraphy was performed in 89 patients at four hours and 24 hours using a digital camera. The lesion to non lesion (L/N) ratio was determined using the camera computer. The T/F ratio was calculated: T/F=((L/N)-24)/((L/N)-4). Three groups were investigated. In 15 patients with metastatic bone carcinoma, T/F ratio was 1.46 +- 0.4. In 47 patients with degenerative joint disease the T/F ratio was 1.05 +- 0.06. In 27 patients with treated metastatic bone carcinoma the T/F ratio was 1.12 +- 0.13. The T/F ratio is significantly (p<0.001) different in patients with metastases compared to patients with benign degenerative disease. Chemotherapeutic and hormonal treatment cause significant (p<0.001) reduction in the T/F ratio. The T/F ratio may have a potential in differentiating degenerative from neoplastic diseases and in the evaluation of patients with bone metastases undergoing treatment

    Objective Cancer-induced bone pain is a common clinical problem in breast cancer patients with bone metastasis. However, the mechanisms driving cancer-induced bone pain are poorly known. Recent studies show that a novel protease, asparaginyl endopeptidase (AEP) plays crucial roles in breast cancer metastasis and progression. We aim to determine the functions and targeted suppress of AEP in a mouse model of breast cancer-induced bone pain. Methods Breast cancer cells with AEP knocked-down or overexpression were constructed and implanted into the intramedullary space of the femur to induce pain-like behavior in mice. AEP-specific inhibitors or purified AEP proteins were further used in animal model. The histological characters of femur and pain ethological changes were measured. The expressions of AEP and neurotrophin receptors (p75NTR and TrkA) in dorsal root ganglion and spinal cord were examined. Results Femur radiographs and histological analysis revealed that cells with AEP knocked-down reduced bone destruction and pain behaviors. However, cells with AEP overexpression elevated bone damage and pain behaviors. Further, Western blot results found that the expressions of p75NTR and TrkA in dorsal root ganglions and spinal cords were reduced in mice inoculated with AEP knocked-down cells. Targeted suppression of AEP with specific small compounds significantly reduced the bone pain while purified recombinant AEP proteins increased bone pain. Conclusions AEP aggravate the development of breast cancer bone metastasis and bone pain by increasing the expression of neurotrophin receptors. AEP might be an effective target for treatment of breast cancerinduced bone pain.

    Prostate cancer (PC) is the most prevalent malignancy in men, with 604,506 new cases diagnosed yearly worldwide. Maintaining bone health is important during all stages of PC, including patients who experience bone loss from androgen-deprivation therapy and patients who develop bone metastases. Patients with bone metastases often experience severe bone pain and are at increased risk for potentially debilitating skeletal-related events. Bisphosphonates are a well-established treatment option for patients with bone metastases from solid tumors and bone lesions from multiple myeloma. Zoledronic acid (ZOL) is the only bisphosphonate (BP) that has been extensively studied in patients with castration-recurrent PC and is indicated for treating patients with bone metastases from PC in conjunction with standard antineoplastic therapy. This review will examine the breadth of evidence supporting a role for ZOL and emerging therapies in managing patients with PC throughout the disease continuum. 2010 Elsevier Inc.

    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.

    Full Text Available A 57-year-old man who presented with urinary retention was found to have a sarcomatoid carcinoma of the urethra. Evaluation with CT scan of the abdomen and pelvis revealed multiple pulmonary nodules and osteolytic lesions of left posterior ribs. After external beam radiation therapy and six cycles of systemic chemotherapy, patient underwent a surgical resection of the urethral cancer. After his surgery, patient was also found to have multiple brain metastases and underwent whole brain radiation therapy, nine months after his initial diagnosis. Sarcomatoid carcinomas of the genitourinary tract are extremely rare tumors that require a very aggressive, multimodal treatment approach.

    Uveal melanoma (UM) is the most common intraocular tumor in adults and liver metastasis is the leading cause of death in UM patients. We have previously shown that NKT cell-deficient mice develop significantly fewer liver metastases from intraocular melanomas than do wild-type (WT) mice. Here, we examine the interplay between liver NKT cells and NK cells in resistance to liver metastases from intraocular melanomas. NKT cell-deficient CD1d(-/-) mice and WT C57BL/6 mice treated with anti-CD1d antibody developed significantly fewer liver metastases than WT mice following either intraocular or intrasplenic injection of B16LS9 melanoma cells. The increased number of metastases in WT mice was associated with reduced liver NK cytotoxicity and decreased production of IFN-γ. However, liver NK cell-mediated cytotoxic activity was identical in non-tumor bearing NKT cell-deficient mice and WT mice, indicating that liver metastases were crucial for the suppression of liver NK cells. Depressed liver NK cytotoxicity in WT mice was associated with production of IL-10 by bone marrow-derived liver cells that were neither Kupffer cells nor myeloid-derived suppressor cells and by increased IL-10 receptor expression on liver NK cells. IL-10(-/-) mice had significantly fewer liver metastases than WT mice, but were not significantly different from NKT cell-deficient mice. Thus, development of melanoma liver metastases is associated with upregulation of IL-10 in the liver and an elevated expression of IL-10 receptor on liver NK cells. This impairment of liver NK activity is NKT cell-dependent and only occurs in hosts with melanoma liver metastases. © 2015 UICC.

    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)

    The presence of bone metastases has excluded participation of prostate cancer patients in exercise intervention studies to date and is also a relative contraindication to supervised exercise in the community setting because of concerns of fragility fracture. However, this group of patients often have developed significant muscle atrophy and functional impairments from prior and continuing androgen deprivation that is exacerbated by subsequent and more intensive interventions such as chemotherapy. The aim of this study is to determine the efficacy and safety of a modular multi-modal exercise program in prostate cancer patients with bone metastases. Multi-site randomized controlled trial in Western Australia and New South Wales to examine the efficacy and safety of a modular multi-modal physical exercise program in 90 prostate cancer survivors with bone metastases. Participants will be randomized to (1) modular multi-modal exercise intervention group or (2) usual medical care group. The modular multi-modal exercise group will receive a 3-month supervised exercise program based on bone lesion location/extent. Measurements for primary and secondary endpoints will take place at baseline, 3 months (end of the intervention) and 6 months follow-up. Delaying or preventing skeletal complication and improving physical function for men with bone metastases would provide clinically meaningful benefits to patients. However, exercise programs must be designed and executed with careful consideration of the skeletal complications associated with bone metastatic disease and cumulative toxicities from androgen deprivation such as osteoporosis and increased risk of fractures. The results from this study will form the basis for the development of a specific exercise prescription in this patient group in order to alleviate disease burden, counteract the adverse treatment related side-effects and enhance quality of life.

    A well-recognized difficulty in assessing the response to therapy for advanced prostate cancer is the infrequency of measurable metastatic disease. The most common metastatic site is bone, and it is manifested by diffuse ostoblastic lesions that cannot be measured reliably to allow for assessments of therapeutic benefits. We assessed the clinical usefulness of quantifying the extent of disease on bone scans in monitoring treatment response in patients with advance prostate cancer using computer-assisted image analysis. Percentage of the positive area on the bone scan (%PABS) was quantified automatically using a personal computer with the NIH Image program. Serial measurements of %PABS in 44 patients with bone metastasis from prostate cancer followed for a mean of 33 month (range 4 to 72) with hormonal therapy were compared with those of the extent of disease (EOD) grades in bone lesions and serum prostate specific antigen (PSA) levels according to treatment response. Serial measurements of EOD grades and %PABS in 13 patients with partial response (PR) disease and those in 12 patients with progressive disease (PD) who did not show bone metastasis progression demonstrated a downward trend during the treatment. On the other hand, changes of EOD grades and %PABS in the remaining 19 patients with PD who showed bone metastasis progression demonstrated an upward trend. Estimated survival curves showed that %PABS was a useful prognostic indicator, with the patients who showed a 25% decline in %PABS surviving longer than the patients who showed a less than 25% decline in %PABS after treatment (p=0.0207). The %PABS is a simple and reproducible estimate of the percentage of the skeleton involving tumors in patients with advanced prostate cancer, and serial measurements of %PABS can assist in monitoring the treatment response in patients with bone metastatic prostate cancer.

    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 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...

    This prospective, epidemiologic study was designed to translate the original Spanish Bone Metastases Quality-of-Life-10 (BOMET-QoL-10) questionnaire and undertake a validation of the translated German version of BOMET-QoL-10 in Germany to assess health-related quality of life (HRQoL) in patients with bone metastases (BM). The translation process included forward and backward translations, and a linguistic validation. Patients aged ≥18 years with histological confirmation of cancer, diagnosed with BM, life expectancy ≥6 months, and fluency in German were eligible for this study (enrolled consecutively in 33 outpatient centers in Germany). Patients were given the German version of BOMET-QoL-10 together with European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire QLQ-C30 and EORTC QLQ-BM22 questionnaires at inclusion, 6 weeks, 3 months, and 6 months after inclusion. A debriefing questionnaire was administered at inclusion to determine patient acceptability and understanding. Data include 364 patients with BM (median age: 68 years; female sex: 71.7%). The BOMET-QoL-10 is brief and clear (median completion time: 5 minutes; >90% of patients completed the questionnaire without assistance). The BOMET-QoL-10 forms only one overall scale. All 10 items showed a substantial correlation with the first factor (factor loading, range: 0.58 - 0.86). BOMET-QoL-10 exhibits high internal consistency and reproducibility (Cronbach's alpha: 0.91; intra-class correlation coefficient: 0.76). BOMET-QoL-10 showed significant correlations (range: 0.69 - 0.79) both with EORTC QLQ-C30 and EORTC QLQ-BM22 within the functioning (physical, social, interference) and symptom (fatigue, pain) scales, displayed significant sensitivity to change in EORTC QLQ-BM22 scores, and proved potential ability to detect change in HRQoL in patients with different disease status. There was a high proportion of females in our study which might represent a limitation. The

    To perform a meta-analysis comparing the diagnostic value of {sup 18}FDG-PET, MRI, and bone scintigraphy (BS) in detecting bone metastases in patients with breast cancer. MEDLINE, EMBASE, Scopus, ScienceDirect, SpringerLink, Web of Knowledge, EBSCO, and the Cochrane Database of Systematic Review databases were searched for relevant original articles published from January 1995 to January 2010. Inclusion criteria was as follows: {sup 18}FDG-PET, MRI or {sup 99m}Tc-MDP BS was performed to detect bone metastases (the number of published CT studies was inadequate for meta-analysis and therefore could not be included in this study); sufficient data were presented to construct a 2 x 2 contingency table; histopathological analysis and/or close clinical and imaging follow-up for at least 6 months were used as the reference standard. Two reviewers independently assessed potentially eligible studies and extracted relevant data. A software program called ''META-DiSc'' was used to obtain the pooled estimates for sensitivity, specificity, diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves, and the *Q index for each modality. Thirteen articles consisting of 23 studies fulfilled all inclusion criteria. On a per-patient basis, the pooled sensitivity estimates for MRI (97.1%) were significantly higher than those for PET (83.3%) and BS (87.0%; P <0.05). There was no significant difference between PET and BS (P <0.05). The pooled specificity estimates for PET (94.5%) and MRI (97.0%) were both significantly higher than those for BS (88.1%; P <0.05). There was no significant difference between PET and MRI (P >0.05). The pooled DOR estimates for MRI (298.5) were significantly higher than those for PET (82.1%) and BS (49.3%; P <0.05). There was no significant difference between PET and BS (P >0.05). The SROC curve for MRI showed better diagnostic accuracy than those for PET and BS. The SROC curve for PET was better than that for BS

    There are three distinct areas of cancer management that make bone health in cancer patients of increasing clinical importance. First, bone metastases are common in many solid tumours, notably those arising from the breast, prostate and lung, as well as multiple myeloma, and may cause major...... morbidity including fractures, severe pain, nerve compression and hypercalcaemia. Through optimum multidisciplinary management of patients with bone metastases, including the use of bone-targeted treatments such as potent bisphosphonates or denosumab, it has been possible to transform the course of advanced...... cancer for many patients resulting in a major reduction in skeletal complications, reduced bone pain and improved quality of life. Secondly, many of the treatments we use to treat cancer patients have effects on reproductive hormones, which are critical for the maintenance of normal bone remodelling...

    Aim of the study. The aim of the study was the evaluation of the diffusion coefficient (ADC) of vertebral metastasis and regular vertebral bodies with diffusion weighted MRI (DWI). DWI evaluates the tissue-specific molecular diffusion of protons. In tissues with high cell densities (neoplasm) a decreased ADC can be expected due to restricted diffusion according to an exaggerated amount of intra- and intercellular membranes (i.e. diffusion barriers). Methods. In 5 breast cancer patients the ADC of both known vertebral metastases and of adjacent regular vertebral bodies were measured with DWI (1.0 T; Phased-Array-Body-Coil; b: 880 and 440 s/mm 2 ). Results. The ADC of regular vertebral bodies (1.3±0.23x10 -3 s/mm 2 ) was significantly (p -3 s/mm 2 ). Conclusions. These data demonstrate that the ADC can be reliably measured in vertebral bodies. The quantitative evaluation of the ADC in vertebral bodies seems to be an objective and comparable parameter for differentiating malign from benign vertebral tissue. (orig.) [de

    Zoledronic acid (ZOL) is a standard therapy for the prevention of skeletal-related events (SREs) in patients with castration-resistant prostate cancer (CRPC). Although prostate-specific antigen (PSA) is an established marker for monitoring prostate cancer patients, correlations between PSA and disease outcomes during ZOL therapy are unclear. To evaluate the relationships among PSA kinetics, bone-directed therapy with ZOL, and clinical outcomes in men with bone metastases from CRPC using a ZOL phase 3 trial database. Exploratory analyses from a phase 3 trial in men with bone metastases from CRPC (n=643) randomized to ZOL or placebo every 3 wk. PSA levels during the first 3 mo of the study were evaluated in linear and logarithmic (log) models stratified using prognostic factors established in a ZOL phase 3 trial and a CRPC nomogram. Relative risks of SREs, bone disease progression (BDP), and death were calculated per 1 log (nanograms per milliliter) PSA increase. Baseline PSA models used the study median (PSA: 77.3 ng/ml) as the high/low cut-off point. A total of 202 placebo- and 434 ZOL-treated patients were assessable. In both groups, PSA increases correlated with significantly increased risks of death, BDP, and first SRE. In the placebo and ZOL groups, associated increases in risk per 1 log (nanograms per milliliter) PSA increase were 29% (p<0.0001) and 10% (p<0.0074), respectively, for BDP, and 24% (p=0.0010) and 13% (p=0.0079), respectively, for first SRE. Limitations include the retrospective nature of these analyses and the potential confounding effects of concurrent antineoplastic therapies. PSA is an important prognostic tool for survival in patients with bone metastases from CRPC, and these analyses show that PSA is also prognostic for BDP and SREs regardless of bone-targeted therapy.

We characterized inpatient and outpatient hospital visits in a national population-based cohort of Danish women with SREs secondary to breast cancer and bone metastases. Methods: We identified first-time breast cancer patients with bone metastases from 2003 through 2009 who had a subsequent SRE (defined as pathologic fracture, spinal cord compression, radiation therapy, or surgery to bone. Hospital visits included the number of inpatient hospitalizations, length of stay, number of hospital outpatient clinic visits, and emergency room visits. The number of hospital visits was assessed for a pre-SRE period (90 days prior to the diagnostic period, a diagnostic period (14 days prior to the SRE, and a post-SRE period (90 days after the SRE. Patients who experienced more than one SRE during the 90-day post-SRE period were defined as having multiple SREs and were followed until 90 days after the last SRE. Results: We identified 569 women with SREs secondary to breast cancer with bone metastases. The majority of women had multiple SREs (73.1%. A total of 20.9% and 33.4% of women with single and multiple SREs died in the post-SRE period, respectively. SREs were associated with a large number of hospital visits in the diagnostic period, irrespective of the number and type of SREs. Women with multiple SREs generally had a higher number of visits compared to those with a single SRE in the post-SRE period, eg, median length of hospitalization was 5 days (interquartile range 0–15 for women with a single SRE and 13 days (interquartile range 4

    [sup 123]I-IMP and bone scintigraphy with [sup 99m]Tc-MDP were consecutively performed in patients with vertebral bone metastases from hepatocellular carcinoma and lumbar spondylosis deformans in a 7-day interval or shorter. The intensity of uptake was compared. Eighteen of the 20 metastatic lesions (90%) were classified as increased uptake areas in [sup 123]I-IMP scintigraphy. MDP-scintigraphy disclosed 16 metastatic lesions (80%), 9 as ''hot'' lesions (56%) and 7 as ''cold'' lesions (44%). [sup 123]I-IMP scintigraphy was negative in all 12 lesions of lumbar spondylosis deformans. Compared to MDP-scintigraphy, [sup 123]I-IMP scintigraphy was more sensitive in detecting vertebral bone metastases of hepatocellular carcinoma with smaller rates of false-positive and false-negative findings.

    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

    The utilization of nuclear medicine bone scanning examinations early in the diagnostic process allows physicians to render prompt and correct treatment in urgent or difficult athletic cases. Bone scanning should be performed for athletic injuries whenever (1) x-rays are normal but bone or joint pain persists; (2) x-rays are positive but it cannot be determined if the findings are acute or chronic; (3) soft-tissue injuries present and x-rays are not useful; and (4) bone pain or joint impairment present without a history of trauma.89 references

    Full Text Available Squamous cell carcinoma (SCC is the second most common type of skin cancer after basal cell carcinoma (BCC. The overall prevalence of BCC is 3 times higher than that of SCC, but this can vary when looking at specific locations such as the hand, where SCC is much more common than BCC. Carcinoma (or epithelioma cuniculatum is a rare variant of SCC. It was originally described as a verrucous carcinoma of the soles. Exceptionally, it can arise in other parts of the skin. We report a rare case of carcinoma cuniculatum of the right thenar region with bone and lymph node involvement.

    The results of an analysis of craniographic findings were provided for 58 patients with primary hyperparathyrosis, 12 with fibrous osteodysplasia, 6 with deforming osteodystrophy, 14 with multiple myeloma and 16 with tumor metastases to the cranial bones. A study was made of some features of roentgenological semiotics (changes in the structure thickness and shapes of the cranial bones) of cranial bone lesions in the above diseases. Differential radiodiagnosis of cranial lesions in hypeparathyroid and deforming osteodystrophy, fibrous osteodysplasia, multiple myeloma and metastatic lesions of the cranial bones should be based not on single signs but on the symptom-complex (x-ray syndrome). For each of the analysed diseases x-ray syndromes were described

    To determine if the histology of a breast malignancy influences the appearance of untreated osseous metastases on FDG PET/CT. This retrospective study was performed under IRB waiver. Our Hospital Information System was screened for breast cancer patients who presented with osseous metastases, who underwent FDG PET/CT prior to systemic therapy or radiotherapy from 2009 to 2012. Patients with invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), or mixed ductal/lobular (MDL) histology were included. Patients with a history of other malignancies were excluded. PET/CT was evaluated, blinded to histology, to classify osseous metastases on a per-patient basis as sclerotic, lytic, mixed lytic/sclerotic, or occult on CT, and to record SUVmax for osseous metastases on PET. Following screening, 95 patients who met the inclusion criteria (74 IDC, 13 ILC, and 8 MDL) were included. ILC osseous metastases were more commonly sclerotic and demonstrated lower SUVmax than IDC metastases. In all IDC and MDL patients with osseous metastases, at least one was FDG-avid. For ILC, all patients with lytic or mixed osseous metastases demonstrated at least one FDG-avid metastasis; however, in only three of seven patients were sclerotic osseous metastases apparent on FDG PET. The histologic subtype of breast cancer affects the appearance of untreated osseous metastases on FDG PET/CT. In particular, non-FDG-avid sclerotic osseous metastases were more common in patients with ILC than in patients with IDC. Breast cancer histology should be considered when interpreting non-FDG-avid sclerotic osseous lesions on PET/CT, which may be more suspicious for metastases (rather than benign lesions) in patients with ILC.

    Purpose: To assess the impact of a population-based intervention to increase the consistency and use of single-fraction radiation therapy (SFRT) for bone metastases. Methods and Materials: In 2012, an audit of radiation therapy prescriptions for bone metastases in British Columbia identified significant interphysician and -center (26%-73%) variation in the use of SFRT. Anonymous physician-level and identifiable regional cancer center SFRT use data were presented to all radiation oncologists, together with published guidelines, meta-analyses, and recommendations from practice leaders. The use of SFRT for bone metastases from 2007 through 2011 was compared with use of SFRT in 2013, to assess the impact of the audit and educational intervention. Multilevel logistic regression was used to assess the relationship between the usage of SFRT and the timing of the radiation while controlling for potentially confounding variables. Physician and center were included as group effects to account for the clustered structure of the data. Results: A total of 16,898 courses of RT were delivered from 2007 through 2011, and 3200 courses were delivered in 2013. The rates of SFRT use in 2007, 2008, 2009, 2010, 2011, and 2013 were 50.5%, 50.9%, 48.3%, 48.5%, 48.0%, and 59.7%, respectively (P<.001). Use of SFRT increased in each of 5 regional centers: A: 26% to 32%; B: 36% to 56%; C: 39% to 57%; D: 49% to 56%; and E: 73% to 85.0%. Use of SFRT was more consistent; 3 of 5 centers used SFRT for 56% to 57% of bone metastases RT courses. The regression analysis showed strong evidence that the usage of SFRT increased after the 2012 intervention (odds ratio 2.27, 95% confidence interval 2.06-2.50, P<.0001). Conclusion: Assessed on a population basis, an audit-based intervention increased utilization of SFRT for bone metastases. The intervention reversed a trend to decreasing SFRT use, reduced costs, and improved patient convenience. This suggests that dissemination of programmatic quality

    Ra-dichloride is an alpha-emitting radiopharmaceutical used in the treatment of bone metastases from castration-resistant prostate cancer. Image-based dosimetric studies remain challenging because the emitted photons are few. The aim of this study was to implement a methodology for in-vivo quantitative planar imaging, and to assess the absorbed dose to lesions using the MIRD approach. The study included nine Caucasian patients with 24 lesions (6 humeral head lesions, 4 iliac wing lesions, 2 scapular lesions, 5 trochanter lesions, 3 vertebral lesions, 3 glenoid lesions, 1 coxofemoral lesion). The treatment consisted of six injections (one every 4 weeks) of 50 kBq per kg body weight. Gamma-camera calibrations for {sup 223}Ra included measurements of sensitivity and transmission curves. Patients were statically imaged for 30 min, using an MEGP collimator, double-peak acquisition, and filtering to improve the image quality. Lesions were delineated on {sup 99m}Tc-MDP whole-body images, and the ROIs superimposed on the {sup 223}Ra images after image coregistration. The activity was quantified with background, attenuation, and scatter correction. Absorbed doses were assessed deriving the S values from the S factors for soft-tissue spheres of OLINDA/EXM, evaluating the lesion volumes by delineation on the CT images. In 12 lesions with a wash-in phase the biokinetics were assumed to be biexponential, and to be monoexponential in the remainder. The optimal timing for serial acquisitions was between 1 and 5 h, between 18 and 24 h, between 48 and 60 h, and between 7 and 15 days. The error in cumulated activity neglecting the wash-in phase was between 2 % and 12 %. The mean effective half-life (T{sub 1/2eff}) of {sup 223}Ra was 8.2 days (range 5.5-11.4 days). The absorbed dose (D) after the first injection was 0.7 Gy (range 0.2-1.9 Gy). Considering the relative biological effectiveness (RBE) of alpha particles (RBE = 5), D{sub RBE} = 899 mGy/MBq (range 340-2,450 mGy/MBq). The

    Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the most frequently occurring histological subtypes of breast cancer, accounting for 80-90% and 10-15% of the total cases, respectively. At the time of diagnosis and surgical resection of the primary tumour, most patients do not have clinical signs of metastases, but bone micrometastases may already be present. Our aim was to develop a novel preclinical ILC model of spontaneous bone micrometastasis. We used murine invasive lobular breast carcinoma cells (KEP) that were generated by targeted deletion of E-cadherin and p53 in a conditional K14cre;Cdh1((F/F));Trp53((F/F)) mouse model of de novo mammary tumour formation. After surgical resection of the growing orthotopically implanted KEP cells, distant metastases were formed. In contrast to other orthotopic breast cancer models, KEP cells readily formed skeletal metastases with minimal lung involvement. Continuous treatment with SD-208 (60 mg/kg per day), an orally available TGFβ receptor I kinase inhibitor, increased the tumour growth at the primary site and increased the number of distant metastases. Furthermore, when SD-208 treatment was started after surgical resection of the orthotopic tumour, increased bone colonisation was also observed (versus vehicle). Both our in vitro and in vivo data show that SD-208 treatment reduced TGFβ signalling, inhibited apoptosis, and increased proliferation. In conclusion, we have demonstrated that orthotopic implantation of murine ILC cells represent a new breast cancer model of minimal residual disease in vivo, which comprises key steps of the metastatic cascade. The cancer cells are sensitive to the anti-tumour effects of TGFβ. Our in vivo model is ideally suited for functional studies and evaluation of new pharmacological intervention strategies that may target one or more steps along the metastatic cascade of events. © 2014 The Authors.

    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.

    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.

    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®

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate (p<0.05). Of 172 post-operative cases, 20.8% (11/53) of those with lymphnode metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymphnode metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.)

    Two case studies are used to discuss topical issues current in follow-up management of patients with early stage breast cancer. These issues include the role of screening and diagnostic bone scintigraphy and patient self-advocacy in clinical management. Breast cancer is common. Standard clinical practice in Australia for patients treated for early stage carcinoma of the breast is regular follow-up, usually lasting 5 years, and often 10 years. There are numerous benefits for patients receiving regular clinical checkups post-treatment of breast cancer. However, the three prime objectives are early detection of recurrence, assessment of treatment-related morbidity, and provision of psychological support. Not surprisingly, a variety of intercurrent clinical events can occur in a population of post-treatment breast cancer patients on long-term follow-up. In this article we describe two interesting cases, each presenting with a solitary new destructive rib lesion highly suggestive of a first clinical diagnosis of metastatic breast cancer. Subsequent biopsy revealed the lesions to be benign. Copyright (1999) Blackwell Science Pty Ltd

    Hypophosphatemia is an important finding in the evaluation of patients with chronic bone pain. Fibroblast-growth factor 23 (FGF23) plays a role in the differential diagnosis of hypophosphatemia. A 34-year-old man had progressive pain in both shoulders and hips due to hypophosphatemic osteomalacia.

    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. 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. 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 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. 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.

    The purpose of this study was to compare the diagnostic accuracy of whole-body MRI (WB-MRI) and bone scintigraphy (BS) for the screening of bone metastases for the first time in a large and homogeneous patient collective with breast cancer in a systematic and controlled study. 213 breast cancer patients were evaluated for bone metastases under randomized, double-blinded and prospective conditions at two hospitals. All participants were examined by WB-MRI and BS over an average period of four days. The examinations were performed separately at two different locations. The WB-MRI protocol included T 1-TSE and STIR sequences. WB-MRI and BS were reviewed independently by experienced radiologists and nuclear medicine specialists in a consensus reading. In 66 % of cases bone metastases were excluded by both procedures, and bone metastases were detected concordantly in 2 % of cases. In 7 % of cases there were discrepant results: in 7 cases BS was false-positive when WB-MRI was negative. In 5 / 7 cases BS was negative when WB-MRI identified bone metastases. In 89 % of cases BS was uncertain when WB-MRI was true-negative. In 17 % of cases WB-MRI showed important (non-) tumor-associated findings. The sensitivity, specificity, positive and negative predictive value and diagnostic accuracy for WB-MRI were 90 %, 94 %, 82 %, 98 % and 99 % and for BS those were 40 %, 81 %, 36 %, 91 % and 93 %.

    Strontium chloride, 89 SrCI 2 , a radiopharmaceutical used for palliative therapy of bone metastases from breast and prostate cancer is produced by irradiation in a nuclear reactor. The analytical quality control procedures are established to confirm the radionuclidic purity of the preparation, its chemical composition and specific activity. Chemical concentration of strontium in the product is determined by complexometry with arsenazo III and chlorides assay by potentiometric titration with silver nitrate. The contamination with chemical impurities is determined by DC graphite spark spectrography. The specific activity and isotonicity of the solution are corrected by addition of natural SrCI 2 and NaCI. 90 Sr is produced in the 89 Sr(n,γ) 90 Sr reaction contributes to impurities. It decays to 90 Y and the activity of 90 Sr can be calculated from the activity of 90 Y. The extraction chromatography on nonionic acrylic ester polymer coated with organic solutions of selective features (Spec resins for Eichrom) is applied for separation of radionuclides. The extraction chromatography system consisting of two columns: strontium selective resin and rare earth elements selective resin was used for separation of 90 Y from 90 Sr in the 89 SrCI 2 solution. The 90 Y and 90 Sr carrier-free solutions used as tracers helped for determination of extraction conditions and efficiency. The concentration of 90 Sr determined in the analysed solution is at the level of 2.10 -4 % which conforms with the data calculated from irradiation parameters. The obtained product, strontium chloride 89 SrCI 2 for injection, forms a sterile and isotonic water solution (pH - 4-7) with specific activity of 89 Sr in the range from 3.5 to 6.3. MBq/mg and radioactive concentration of 37.5 MBq/ml. The radionuclidic purity of the obtained preparations is at the level of 99.9% with respect to 89 Sr

    Over the past 6 years, the authors evaluated 300 patients with hepatoma as part of phase 1 and 2 treatment protocol trials. Analysis of the available clinical data and radiographic studies revealed 22 patients (7.3%) with skeletal metastases demonstrated by radiography, computed tomography (CT), and/or nuclear scintigraphy. The plain film appearance of skeletal metastases from hepatoma was osteolytic in all cases. CT scanning best demonstrated the expansile, destructive nature of these metastases, which were often associated with large, bulky soft-tissue masses. Skeletal metastases from hepatomas demonstrated increased radiotracer uptake on standard bone scans and were gallium avid, similar to the hepatoma itself. In addition, they could be targeted therapeutically with I-131 antiferritin immunoglobulin. The most frequent sites of skeletal metastases were the ribs, spine, femur, pelvis, and humerus. An initial symptom in ten patients was skeletal pain corresponding to the osseous metastases. In five patients, pathologic fractures of the proximal femur or humerus developed and required total hip replacement or open-reduction internal fixation. Patients with long-standing cirrhosis or known hepatocellular carcinoma who also have skeletal symptoms should be evaluated for possible osseous metastases

    In the past 20 years, the incidence of prostate cancer has risen rapidly. It has been ranked as the third most common malignant tumor of the male genitourinary system. Testicular metastasis is uncommon in prostate cancer. Most cases are incidentally found in the treatment of prostate cancer with orchiectomy. Therefore, we believed it was necessary to report the case of our patient with this disease. We present a case of a 69-year-old Han Chinese man with a high total prostate-specific antigen level. A transrectal ultrasound-guided prostate biopsy was performed. A pathology report showed prostate cancer tissue with a Gleason score of 4 + 4 = 8/10. Imaging findings suggested that the prostate cancer tissue involved bilateral seminal vesicles and multiple bones. Next, radioactive seed implantation was carried out, and endocrine therapy was continued after the operation. Then enlargement of the left scrotum was found along with a total prostate-specific antigen level of 19.21 ng/ml. Computed tomography of the middle abdomen and pelvic cavity revealed 2.0 × 1.3-cm lesions of the left testis. The patient underwent a left testicular high resection and right orchiectomy. The postoperative pathology report showed metastatic prostate cancer cells in the left testis. Testicular metastasis of prostate cancer is rare. Therefore, a testicular physical examination is necessary for patients without relapse to avoid a missed diagnosis. Testicular metastasis should be treated according to the principle of treatment for advanced prostate adenocarcinoma if testicular metastasis of prostate adenocarcinoma is detected.

    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.)

    The theranostic nanobiomaterials have received much attention of the scientific community around the world since these materials can accumulate spontaneously and selectively in tumor regions, being internalized by its cells and promoting simultaneously the diagnosis and the treatment of many types of cancer. Among many nanobiomaterials able to act as theranostic systems, hydroxyapatite nanorods (HA) stand up as promising theranostic agents to act in the early stages of osteosarcoma due to their important properties such as biocompatibility, bioactivity and high affinity to bone tissues, being able to act as drug delivery systems and radioisotopes carries, among many others biomedical applications. Apatite structures such as HA have high stability and flexibility that make them susceptible to the doping process and the conjugation with other crystallographic phases to confer theranostic properties to the material. However, the performance of these materials depends directly on the ability of these nanoparticles to bind to tumor cells. The process of surface functionalization of hydroxyapatite improves the adhesion of this material to the cell membranes. An important property acquired by hydroxyapatite functionalized with folic acid refers to the active and preferential accumulation in tumor sites of osteosarcoma. The present work consists in the investigation of theranostic systems through the synthesis of hydroxyapatite nanorods doped with gadolinium and copper, and functionalized with folic acid (FA). The process of neutron activation enabled the production of the radioisotopes 32 P, 159 Gd and 64 Cu in the HA lattice. A systematic study of the morphological and physicochemical characteristics was carried out, as well as the characterization of the magnetic and structural properties of these samples, including a study on the chemical interaction between folic acid, gadolinium, tenorite and the surface of nanoparticles. The synthesized materials were characterized

    Purpose: There is abundant evidence that a single fraction (SF) of palliative radiation therapy (RT) for bone metastases is equivalent to more protracted and costly multiple fraction courses. Despite this, there is low utilization of SFRT internationally. We sought to determine the utilization of SFRT in a population-based, publicly funded health care system. Methods and Materials: All consecutive patients with bone metastases treated with RT during 2007 to 2011 in British Columbia (BC) were identified. Associations between utilization of SFRT and patient and provider characteristics were investigated. Results: A total of 16,898 courses of RT were delivered to 8601 patients. SFRT was prescribed 49% of the time. There were positive relationships among SFRT utilization and primary tumor group (P<.001; most commonly in prostate cancer), worse prognosis (P<.001), increasing physician experience (P<.001), site of metastases (P<.001; least for spine metastases), and area of training (P<.001; most commonly for oncologists trained in the United Kingdom). There was wide variation in the prescription of SFRT across 5 regional cancer centers, ranging from 25.5% to 73.4%, which persisted after controlling for other, potentially confounding factors (P<.001). Conclusions: The large variability in SFRT utilization across BC Cancer Agency (BCCA) cancer centers suggests there is a strong cultural effect, where physicians' use of SFRT is influenced by their colleagues' practice. SFRT use in BC was similar to that in other Canadian and western European reports but strikingly higher than in the United States. Further work is needed to standardize SFRT prescribing practices internationally for this common indication for RT, with the potential for huge health system cost savings and substantial improvements in patients' quality of life.

    Full Text Available Aim: Peripheral cytokines contribute to arthritis and bone cancer pain through sensory nerve actions. However, increased spinal cytokine and glial filament expression, coined neuroinflammation, has also been proposed to play a part in chronic pain. Therefore, spinal cord, dorsal root ganglia and circulating cytokines were compared in murine arthritis and bone cancer models in relationship to behavioral signs of pain. Methods: Exploratory behaviors were studied after intra-articular complete Freund's adjuvant or bone intramedullary sarcoma cell injection. Nervous tissue and blood cytokine expression were determined by real-time polymerase chain reaction (PCR and multiplex immunoassays, respectively. Results: PCR analysis did not reveal any hallmark of spinal neuroinflammation in spontaneously-behaving mice with cartilage or bone lesions. However, imposed paw stimulation during joint inflammation increased spinal interleukin-1β (IL-1β expression. Spontaneous paw guarding during rearing was displayed by animals with joint inflammation and bone destruction and was accompanied by increased circulating IL-6 and monocyte chemoattractant protein-1, respectively. In addition, dorsal root ganglia were found to constitutively express receptors for this chemotactic cytokine. Conclusion: Our findings indicate that spinal neuroinflammation is not a necessary condition for chronic pain and suggest that circulating cytokine action in dorsal root ganglia may contribute to experimental joint inflammation and bone cancer pain.
