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

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

    @@ The majority of men with advanced prostate cancer develop bone metastases as opposed to metastases at other sites.1 It has been unclear why prostate cancer selectively metastasizes to and proliferates in bone.Recently, Shiozawa et al.Delineated a mechanism that may account for the establishment of prostate cancer in bone.2 Specifically, they identified that prostate cancer cells compete with hematopoietic stem cells (HSC) for the osteoblast in the HSC niche of the bone.Defining the mechanisms through which prostate cancer cells establish themselves in bone is critical towards developing effective therapeutic strategies to prevent or target bone metastases.

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

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

    2011-01-01

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

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

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

    Full Text Available 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.

    Full Text Available Background/Aim. Detection of metastatic bone disease by skeletal scintigraphy is a classical application of nuclear medicine in cancer patients. Detection of bone metastases in patients with lung cancer is necessary for an appropriate treatment modality. The aim of this study was to report the frequency and imaging characteristics of bone metastases detected by bone scintigraphy (BS using technetium-99m phosphonates in patients with lung cancer. Methods. We retrospectively analyzed a total of one hundred patients (78 males and 22 females, mean age of 63.3 years, with the diagnosis of lung cancer, who underwent BS during a three-year period (2003−2005. Scintiscans were classified as positive, negative and suspicious with regard to the presence of bone metastases. Results. The incidence of positive, negative and suspicious findings were 57%. 32% and 11%, respectively. Out of 57 patients with bone metastases, 51 had multiple asymmetric foci of increased tracer activity localized in the ribs, spine, extremities, pelvis, sternum, scapula and skull in 72%, 54%, 49%, 37%, 12%, 9% and 5% of scans, respectively. BS revealed solitary metastases in 6 of the patients. The lesions were located in the lower limbs in three patients and in the upper limbs, pelvis and sternum in the remaining three patients. Conclusion. Bone scintigraphy plays a significant role in staging and selecting of patients for curative lung surgery. Due to the fact that metastatic involvment of the extremities was frequently shown, our study suggests that systematic inclusion of the limbs in BS acquisition should be obligatory.

    The administration of a radionuclide in unsealed source whose radiation will destroy cells that have selectively accumulated product is called radiometabolic therapy. The management of bone pain is a major problem, particularly in cases of breast or prostate where the presence of metastases can remain compatible with long-term survival of cancer patients. In this context, the radiometabolic therapy reduces the pain secondary to bone metastases, in association or not with analgesics. This technique is rarely prescribed as first-line. It can also be combined with external beam radiotherapy or chemotherapy, if clinical conditions permit (due to the increased risk of hematologic toxicity). In this setting, the currently used substances are Metastron® and Quadramet®. Recently, a new product, radium chloride (or Alpharadin®) has shown efficacy in bone metastases from prostate cancer, particularly in terms of bone pain palliation, but also of increased overall survival. In addition, this product has virtually no hematologic toxicity.

    The development of novel therapies for breast cancer bone metastasis is a major unmet medical need. Toward that end, we have constructed an oncolytic adenovirus, Ad.dcn, and a nonreplicating adenovirus, Ad(E1-).dcn, both containing the human decorin gene. Our in vitro studies showed that Ad.dcn produced high levels of viral replication and the decorin protein in the breast tumor cells. Ad(E1-).dcn-mediated decorin expression in MDA-MB-231 cells downregulated the expression of Met, β-catenin, and vascular endothelial growth factor A, all of which are recognized decorin targets and play pivotal roles in the progression of breast tumor growth and metastasis. Adenoviral-mediated decorin expression inhibited cell migration and induced mitochondrial autophagy in MDA-MB-231 cells. Mice bearing MDA-MB-231-luc skeletal metastases were systemically administered with the viral vectors, and skeletal tumor growth was monitored over time. The results of bioluminescence imaging and X-ray radiography indicated that Ad.dcn and Ad(E1-).dcn significantly inhibited the progression of bone metastases. At the terminal time point, histomorphometric analysis, micro-computed tomography, and bone destruction biomarkers showed that Ad.dcn and Ad(E1-).dcn reduced tumor burden and inhibited bone destruction. A nonreplicating adenovirus Ad(E1-).luc expressing the luciferase 2 gene had no significant effect on inhibiting bone metastases, and in several assays, Ad.dcn and Ad(E1-).dcn were better than Ad.luc, a replicating virus expressing the luciferase 2 gene. Our data suggest that adenoviral replication coupled with decorin expression could produce effective antitumor responses in a MDA-MB-231 bone metastasis model of breast cancer. Thus, Ad.dcn could potentially be developed as a candidate gene therapy vector for treating breast cancer bone metastases.

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

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

    Full Text Available Abstract Background The invasion of a new species into an established ecosystem can be directly compared to the steps involved in cancer metastasis. Cancer must grow in a primary site, extravasate and survive in the circulation to then intravasate into target organ (invasive species survival in transport. Cancer cells often lay dormant at their metastatic site for a long period of time (lag period for invasive species before proliferating (invasive spread. Proliferation in the new site has an impact on the target organ microenvironment (ecological impact and eventually the human host (biosphere impact. Results Tilman has described mathematical equations for the competition between invasive species in a structured habitat. These equations were adapted to study the invasion of cancer cells into the bone marrow microenvironment as a structured habitat. A large proportion of solid tumor metastases are bone metastases, known to usurp hematopoietic stem cells (HSC homing pathways to establish footholds in the bone marrow. This required accounting for the fact that this is the natural home of hematopoietic stem cells and that they already occupy this structured space. The adapted Tilman model of invasion dynamics is especially valuable for modeling the lag period or dormancy of cancer cells. Conclusions The Tilman equations for modeling the invasion of two species into a defined space have been modified to study the invasion of cancer cells into the bone marrow microenvironment. These modified equations allow a more flexible way to model the space competition between the two cell species. The ability to model initial density, metastatic seeding into the bone marrow and growth once the cells are present, and movement of cells out of the bone marrow niche and apoptosis of cells are all aspects of the adapted equations. These equations are currently being applied to clinical data sets for verification and further refinement of the models.

    Full Text Available Context: Bone marrow (BM metastases are an integral part of tumor dissemination in many malignancies. Prostate carcinoma, which has high tendency to metastasize to bone, shown to have affinity for endosteal niche as well as tendency to compete with hematopoietic cells to home in BM. This marrow dissemination can be confidently proved by histopathological examination of BM. Aims: In this study, we are trying to detect the presence of metastases and micrometastases in BM of prostate carcinoma patients with the help of immunohistochemical markers prostate-specific antigen (PSA and prostate-specific acid phosphatase and correlate the findings with American Joint Committee on Cancer Tumor, Node and Metastasis 7 th (2010 classification, serum PSA, and biopsy Gleason′s score. Materials and Methods: We performed BM examination and hematological workup of 11 known prostate carcinoma patients including metastatic cases also, during our study period of 1 year. The BM biopsy sections and clot sections were used to carry out immunohistochemistry. The data were analyzed by using SPSS (Statistical Package for Social Sciences version 15.0 statistical analysis software. Results: We found that two patients were positive for metastases in BM out of the 11. Both of these patients already had metastases to other site with very high serum PSA levels. Anemia was common hematological alteration in both of them and one of them showed increased osteoblasts in the aspirate film. Conclusion: Taking into account our small sample size and short study duration, we conclude that further large sized future studies with long-term follow-up in to this BM dissemination by prostate cancer cells could open new horizons to understand the biology of metastasis of this common malignancy and also provide more effective therapeutic options as well as prognostic implications in these patients.

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

    Full Text Available Channing J Paller,1 Michael A Carducci,1 George K Philips21Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, Baltimore, MD, USA; 2Georgetown Lombardi Comprehensive Cancer Center, Washington DC, USAAbstract: This article reviews the problem of bone disease in prostate cancer and the evolving role of the novel agent denosumab, a fully human monoclonal antibody that inhibits the receptor activator of nuclear factor-ΚB ligand, in suppressing bone resorption and offering bone protection in this disease. Prostate cancer frequently metastasizes to bone, and additionally its treatment with androgen deprivation leads to accelerated bone loss resulting in clinically relevant skeletal complications associated with disabling symptoms. Among the bone-targeting therapeutic strategies investigated for the prevention of bone complications, the potent bisphosphonate zoledronic acid has been the most widely used agent for bone protection in the past decade. Denosumab is the first among a new class of osteoclast-targeting agents to show superior efficacy in several clinical scenarios in both prostate and breast cancer, as well as in osteoporosis, but the focus of this review will be on its role in prostate cancer. The safety and efficacy of denosumab versus zoledronic acid was established in a randomized trial, demonstrating a delay in skeletal-related events in metastatic castration-resistant prostate cancer patients. This study led to the approval of denosumab in the US. The chief risks of denosumab were hypocalcemia and osteonecrosis of the jaw. Denosumab was also approved for fracture risk reduction in patients on androgen-deprivation therapy for nonmetastatic prostate cancer. Although denosumab extended bone metastasis-free survival in a Phase III trial in men with castration-resistant nonmetastatic prostate cancer to a statistically significant degree, a Food and Drug Administration committee found that the effect was not sufficiently clinically

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

    Bone is the most common site for breast cancer metastases, occurring in up to 70% of those with metastatic disease. In order to effectively manage these patients, it is essential to have consistent, reproducible and validated methods of assessing response to therapy. We present current clinical practice of imaging response assessment of bone metastases. We also review the biology of bone metastases and measures of response assessment including clinical assessment, tumour markers and imaging techniques; bone scans (BSs), computed tomography (CT), positron emission tomography, magnetic resonance imaging (MRI) and whole-body diffusion-weighted MRI (WB DW-MRI). The current standard of care of BSs and CT has significant limitations and are not routinely recommended for the purpose of response assessment in the bones. WB DW-MRI has the potential to address this unmet need and should be evaluated in clinical trials.

    Bone metastases have a major impact on morbidity and on mortality in cancer patients. Despite its clinical relevance, metastasis remains the most poorly elucidated aspect of carcinogenesis. The biological mechanisms leading to bone metastasis establishment have been referred as "vicious circle," a complex network between cancer cells and the bone microenvironment. This review is aimed to underline the new molecular targets in bone metastases management other than bisphosphonates. Different pathways or molecules such as RANK/RANKL/OPG, cathepsin K, endothelin-1, Wnt/DKK1, Src have recently emerged as potential targets and nowadays preclinical and clinical trials are underway. The results from those in the advanced clinical phases are encouraging and underlined the need to design large randomised clinical trials to validate these results in the next future. Targeting the bone by preventing skeletal related events (SREs) and bone metastases has major clinical impact in improving survival in bone metastatic patients and in preventing disease relapse in adjuvant setting.

    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

    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 {sup 18}F FDG PET/CT seems to exhibit high specificity and accuracy in detecting bone metastases. However, there is a limitation of {sup 18}F FDG PET in assessing sclerotic bone metastases because some lesions may be undetectable. Recent studies showed that {sup 18}F fluoride PET/CT is more sensitive than WBBS in detecting bone metastases. This study aims to evaluate the usefulness of {sup 18}F fluoride PET/CT by comparing it with WBBS and {sup 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 {sup 99m}Tc MDP WBBS, {sup 18}F FDG PET/CT and {sup 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. {sup 18}F fluoride PET/CT, {sup 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 {sup 18}F fluoride PET/CT were 94.2%, 46.3%, 57.7% and 91.2%, respectively. Most true metastatic lesions of {sup 18}F fluoride PET/CT had osteosclerotic change (45/49, 91.8%), and only four lesions showed osteolytic change. Most lesions on {sup 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 {sup 18}F FDG PET/CT were identified on {sup 18}F fluoride PET/CT. {sup 18}F FDG PET/CT in detecting osteosclerotic metastatic lesions. {sup 18}F fluoride PET/CT might be useful in evaluating osteosclerotic metastases in breast cancer patients.

    Bone metastases are usually seen on imaging studies as lytic lesions and less often as sclerotic or mixed lesions. We report an exceedingly unusual case of breast cancer identified after magnetic resonance imaging showed bone metastases with fluid-fluid levels in the spine and sacrum. Bone images containing fluid-fluid levels are usually solitary abnormalities produced by aneurismal bone cysts. The fluid-fluid level is due to bleeding within the tumor followed by layering of the blood components based on density differences. Only two other cases of bone metastases with multiple fluid-fluid levels have been reported. Although fluid-fluid levels are exceedingly rare, clinicians should be aware that they might indicate a malignancy, particularly when they are multiple.

    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.

    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.

    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.

    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

    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.)

    Full Text Available Abstract: Background. Aberrant promoter methylation of classical tumor suppressor genes occurs frequently during carcinogenesis. Several lines of evidences suggest that this epigenetic change also regulates microRNAs expression and may represent a potential molecular marker for cancer. Methods. We examined the methylation status at the hsa-miR-9-1 gene promoter in a series of 66 breast cancer cases by methylation sensitive PCR (MSP analysis. For 43 of the 66 patients paired normal breast tissue and/or pre invasive (ADH, DCIS lesions were also available. As control methylation status was determined on 6 normal breast tissues obtained from reductive mammoplasty.   Results. Methylation at mir-9-1 gene was detected in 32 out of 66 breast tumours (49% and in none of the 6 normal breast tissues derived from reductive mammoplasty (P=0.02 χ2- Test. In all cases the same methylation status was demonstrated in tumour specimen, paired normal breast tissues and/or pre-invasive (ADH and DCIS lesions. An higher frequency of methylation was found in patients showing metastases at diagnosis as compared with non metastatic patients (P=0.03 χ2-Test. Moreover, methylation at mir-9-1 gene was more frequent in patients showing bone metastases as first metastatic sites (P=0.04 χ2-Test, and in the subgroup of patients developing only bone metastases as compared with patients developing metastases  to visceral organs (P=0.03 χ2-Test. Conclusions. This study give further evidence of epigenetic mechanisms as regulators of miR-9 expression in breast cancer. Moreover, our results suggest an association between hypermethylation  at the miR-9-1 gene and metastatic site.

    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.)

    To provide practice guidelines and clinical recommendations on preferred standard palliative radiation therapy of bone metastases as well as metastatic spinal cord compression (MSCC) for metastatic breast cancer patients. Methods: The breast cancer expert panel of the German Society of Radiation Oncology (DEGRO) performed a comprehensive survey of the literature comprising recently published data from clinical controlled trials. The literature search encompassed the period 1995-2008 using databases of PubMed and Guidelines International Network (G-I-N). Search terms were ''breast cancer'', ''bone metastasis'', ''osseous metastasis'', ''metastatic spinal cord compression'' as well as ''radiotherapy'' and ''radiation therapy''. Clinical recommendations were formulated based on the panel's interpretation of the level of evidence referring to the criteria of evidence-based medicine. Results: Different therapeutic goals (pain relief, local tumor control, prevention or improvement of motor deficits, stabilization of the spine or other bones) require complex approaches considering individual factors (i.e. life expectancy, tumor progression at other sites). Best results are achieved by close interdisciplinary cooperation minimizing the interval between diagnosis and onset of treatment. Most important criteria for prognosis and choice of treatment (mostly combined multimodal therapy) are neurologic status at diagnosis of MSCC, time course of duration and progression of the neurologic symptoms. Radiation therapy is effective and regarded as treatment of choice for MSCC with or without motor deficits and/or bone metastases, which do not need immediate surgical intervention. It may be used either postoperatively or as primary treatment in case of inoperability. An optimal dose fractionation schedule or optimal standard dose for treatment of bone

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

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

    Directory of Open Access Journals (Sweden)

    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.

    Prostate cancer bone metastases occur frequently in advanced cancer and this is matter of particular attention, due to the great impact on patient's management and considering that a lot of new emerging therapeutic options have been recently introduced. Imaging bone metastases is essential to localize lesions, to establish their size and number, to study characteristics and changes during therapy. Besides radiological imaging, nuclear medicine modalities can image their features and offer additional information about their metabolic behaviour. They can be classified according to physical characteristics, type of detection, mechanism of uptake, availability for daily use. The physiopathology of metastases formation and the mechanisms of tracer uptake are essential to understand the interpretation of nuclear medicine images. Therefore, radiopharmaceuticals for bone metastases can be classified in agents targeting bone (99mTc-phosphonates, 18F-fluoride) and those targeting prostatic cancer cells (18F-fluoromethylcholine, 11C-choline, 18F-fluorodeoxyglucose). The modalities using the first group of tracers are planar bone scan, SPECT or SPECT/CT with 99mTc-diphosphonates, and 18F-fluoride PET/CT, while the modalities using the second group include 18F/11C-choline derivatives PET/CT, 18F-FDG PET/CT and PET/CT scans with several other radiopharmaceuticals described in the literature, such as 18F/11C-acetate derivatives, 18F-fluoro-5α-dihydrotestosterone (FDHT), 18F-anti-1-amino-3-fluorocyclobutane-1-carboxylic acid (FACBC), 18F-2'-fluoro-5-methyl-1-β-D-arabinofuranosyluracil (FMAU) and 68Ga-labeled-prostate specific membrane antigen (PMSA) PET/TC. However, since data on clinical validation for these last novel modalities are not conclusive and/or are not still sufficient in number, at present they can be still considered as promising tools under evaluation. The present paper considers the nuclear modalities today available for the clinical routine. This overview wants

    The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival of patients by 50%. Bone metastases represent a frequent complication especially of follicular thyroid cancer and severely reduce the quality of life causing pain, fractures, and spinal cord compression. Diagnosis is established by correlating clinical suspicion with imaging. Imaging is essential to detect, localize, and assess the extension of the lesions and should be used in conjunction with clinical evidence. Bone metastases are typically associated with elevated markers of bone turnover, but these markers have not been evaluated in differentiated thyroid cancer. Skeletal and whole-body magnetic resonance imaging and fusion 2-deoxy-2-[18F]fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) are the best anatomic and functional imaging techniques available in specialized centers. For well-differentiated lesions, iodine-PET scan combined (124)I-PET/CT is the newest imaging development and (131)I is the first line of treatment. Bisphosphonates reduce the complications rate and pain, alone or in combination with radioiodine, radionuclides, or external beam radiotherapy and should be employed. Surgery and novel minimally invasive consolidation techniques demand an appropriate patient selection for best results on a multimodal approach. Basic research on interactions between tumor cells and bone microenvironment are identifying potential novel targets for future more effective therapeutic interventions for less differentiated tumors.

    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.

    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

Methods A total of 76 patients with bone metastases in breast cancer among 172 breast cancer patients during 2007 to 2010 were retrospectively analysed. Factors such as age, pathological types, axillary lymph node metastases and their number, HER-2, estrogen and progesteron receptor, tumor size, Ki-67 were analysed to clarify whether there was any correlation with bone metastases in breast cancer. Results Bone metastases in breast cancer were associated with axillary lymph node metastases and their number, HER-2, estrogen and progesteron receptor, Ki-67,but there was no correlation with age. Conclusion Breast cancers patients with more than 4 axillary lymph node metastases, positive HER-2, positive estrogen and progesteron receptor and high expression of Ki-67 are more likely to undergo bone metastases. These patients should strengthen the regular follow-up after operation. Patients who have several risk factors should use bone protection drugs after operation and adjuvant chemotherapy as preventive measures.

    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.

    Objective: To investigate the risk factors of bone metastases in breast carcinoma. Methods: By cross sectional study, the data of 225 breast cancer patients who were inpatients in four hospitals in Hangzhou were analyzed. All patients underwent total body bone scan with single photon emission computed tomography (SPECT) at least once during 1995 to 2000. Results: All patients were followed-up to 294 months after operation, bone metastases were found in 113 cases, suspected bone metastases 3 cases, with a bone metastases rate of 50.9% (113/222). Multivariate analysis by Cox's proportional hazards regression model showed that there were four risk factors of bone metastases in breast cancer: (1) clinical stage, I(IV stages with a hazard ratio of bone metastases of 1.945, 95% confidence interval 1.396(2.710; (2) number of invaded axillary lymph nodes, with a hazard ratio of 1.039, 95% confidence interval 1.0142(1.068; (3) skeletal complications (yes vs. no), with a hazard ratio of bone metastases of 1.722, 95% confidence interval 1.060(2.796; (4) age at the time of surgery or diagnosis, with a hazard ratio of 2.048, 95% confidence interval 1.123(3.876 for patients of age 40(50 y versus patients bellow 40 y of age and 2.837, 95% confidence interval 1.473(5.465 for patients of age above 50 y versus patients of ages between 40 and 50. Kaplan-Meier curves showed that for patients with more than 5 invasive axillary lymph nodes, compared with those with 1(5, the bone metastasis rates increased significantly ((2 =6.3319, P=0.012). Conclusion: The clinical stage, number of metastatic axillary lymph nodes, age at the time of operation and skeletal complications are essential risk factors of bone metastases.

As a result, more interventional studies now measure patient’s QOL as a meaningful endpoint. However, well-developed bone metastases specific quality of life instruments are lacking. A literature review was conducted to better understand the nature of QOL instruments used in bone metastases trials. A total of 47 articles evaluating QOL in patients with bone metastases were identified. Twenty-five different instruments were used to evaluate QOL with study-designed questionnaires and the EORTC QLQ-C30 being most commonly employed. Many studies used more than one scale or instrument to measure QOL. This makes it difficult to compare QOL in bone metastases patients across studies and come to any formal conclusions. Therefore, this review demonstrates the need to develop a bone module that can be used across countries in future clinical trials.Keywords: bone metastases, quality of life, QOL instrument, review

    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.

    Distant metastases at primary diagnosis are a prognostic key factor in breast cancer patients and play a central role in therapeutic decisions. To detect them, chest X-ray, abdominal ultrasound, and bone scintigraphy are performed as standard of care in Germany and many centers worldwide. Although FDG PET detects metastatic disease with high accuracy, its diagnostic value in breast cancer still needs to be defined. The aim of this study was to compare the diagnostic performance of FDG PET with conventional imaging. Patients, methods: a retrospective analysis of 119 breast cancer patients who presented for staging was performed. Whole-body FDG-PET (n = 119) was compared with chest X-ray (n = 106) and bone scintigraphy (n = 95). Each imaging modality was independently assessed and classified for metastasis (negative, equivocal and positive). The results of abdominal ultrasound (n = 100) were classified as negative and positive according to written reports. Imaging results were compared with clinical follow-up including follow-up imaging procedures and histopathology. Results: FDG-PET detected distant metastases with a sensitivity of 87.3% and a specificity of 83.3%. In contrast, the sensitivity and specificity of combined conventional imaging procedures was 43.1% and 98.5%, respectively. Regarding so-called equivocal and positive results as positive, the sensitivity and specificity of FDG-PET was 93.1% and 76.6%, respectively, compared to 61.2% and 86.6% for conventional imaging. Regarding different locations of metastases the sensitivity of FDG PET was superior in the detection of pulmonary metastases and lymph node metastases of the mediastinum in comparison to chest X-ray, whereas the sensitivity of FDG PET in the detection of bone and liver metastases was comparable with bone scintigraphy and ultrasound of the abdomen. Conclusions: FDG-PET is more sensitive than conventional imaging procedures for detection of distant breast cancer metastases and should be

    Full Text Available Bone scintigraphies are widely applied for detecting bone metastases. The aim of this study was to investigate distribution features of bone metastases in pulmonary and prostate cancers. Bone scintigraphies were performed in 460 patients with pulmonary cancer and 144 patients with prostate cancer. Patients were divided into three groups according to the total number of bone metastases: few bone metastases, moderate bone metastases, and extensive bone metastases. We compared the distribution of bone metastases in the two cancers, and analyzed the relationship between the distribution of metastatic lesions and their metastatic patterns. A total of 2279 and 2000 lesions of bone metastases were detected in 258 patients with pulmonary cancer and 102 patients with prostate cancer, respectively. In patients with few bone metastases, the distributions of metastatic lesions in the vertebrae (χ2 = 16.0, P = 0.000 and thoracic bones (χ2 = 20.7, P = 0.002 were significantly different between pulmonary and prostate cancers. In cases with moderate bone metastases, the distributions in the vertebrae (χ2 = 6.6, P = 0.010, pelvis (χ2 = 15.1 P = 0.000, and thoracic bones (χ2 = 38.8, P = 0.000 were also significantly different between the two cancers. However, in patients with extensive bone metastases, the distributions were very similar. As the total number of bone metastases increased, their distribution in pulmonary cancer did not noticeably change, but the distribution in the vertebrae and thoracic bones of prostate cancer patients significantly changed. Accordingly, the distribution characteristics of bone metastases differed in pulmonary and prostate cancers, mainly in the early stages of metastasis.

The qualities of the studies were evaluated with QUADAS quality assessment tool. A software program, Meta-disc, was used to obtain the pooled estimates and heterogeneity test for sensitivity, specificity, SROC curve, and so on. Finally the 17 article were included. On a per-patient basis, the pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (LR+), negative likelihood ratio (LR-), diagnostic odds ratio (DOR), Q*, SROC area under curve for 99mTc-MDP bone scan and computed tomography (CT) were 0. 87 and 0.99, 0.81 and 0.98, 3.88 and 13.86, 0.2 and 0.03, 27.73 and 612.17, 0.8418 and 0.9732, 0.9097 and 0.9952, respectively. On a per-focus basis, the pooled SEN, SPE, LR+, LR-, DOR, Q*, SROC area under curve for 99mTc-MDP bone scan was 0.86, 0.97, 13.32, 0.16, 102.4, 0.8944, 0.9528, respectively. For CT, only 1 article were included. This paper demonstrate: whether 99mTc-MDP or CT both have high diagnostic efficiency for bone metastase of breast cancer.

    Objective: To evaluate the long-term efficacy and safety of pamidronate disodium in patients with bone lesions secondary to advanced breast carcinoma. Methods: A retrospective chart review was conducted of 62 patients receiving intravenous pamidronate disodium for metastatic breast cancer. The proportion of patients experiencing at least one skeletal related event (SRE) after 12 months of therapy was determined.Results: The proportion of patients who had an SRE was 29.00% (18 individuals) and the median time to first event was greater than 350 days. Radiotherapy(11 individuals)and pathologic fracture(6 individuals)were the most frequent type of SRE, while cord compression(1 individuals) and hypercalcaemia(0 individuals) were rare. A total of 37 individuals had transient hypocalcaemia without any clinical symptom. No significant creatinine abnormalities were encountered. There were no clinically relevant changes of calcium ,phosphate and creatinine before and after therapy.Conclusion: Long-term treatment with pamidronate disodium significantly reduces and delays skeletal morbidity from osteolytic metastases . Prolonged therapy was well tolerated. This study suggests that the rate of clinically relevant SREs is substantially lower than the event rate observed in phase III clinical trials.

    Cancers prone to spread to bone include prostate, lung, kidney, breast and thyroid cancers. While bone scanner has been widely used in the past decades, PET-based imaging modalities are increasingly used. Current modalities of PET imaging of bone metastases include tumor and inflammatory targeting with FDG-PET, bone imaging with NaF-PET, and direct cancer-specific markers such as FDOPA-PET or PET using choline. The cancer-specific metastatic patterns and the relative prognosis conferred by osseous metastases (versus visceral metastases) may determine the need for bone scan, FDG-PET for the detection of bone metastases. Because some cancers have a mixed skeletal and visceral, cocktails PET radiopharmaceuticals may also be discussed in the future. The cancer-specific context and performances of bone scan and PET imaging are discussed.

    {sup 153}Sm-ethylenediaminetetramethylenephosphonic acid (EDTMP; Quadramet {sup registered}) is indicated for the treatment of painful bone metastases, whereas zoledronic acid (Zometa {sup registered}) is indicated for the prevention of skeletal complications. Because of the different therapeutic effects, combining the treatments may be beneficial. Both, however, accumulate in areas with increased osteoblastic activity. Possible drug interactions were investigated. Patients with hormone-refractory prostate cancer were treated with 18.5 MBq/kg {sup 153}Sm-EDTMP in weeks 1 and 3 and with 37 MBq/kg in week 15. Treatment with 4 mg zoledronic acid began in week 3 and continued every 4 weeks through week 23. In weeks 3 and 15, zoledronic acid was administered 2 days before {sup 153}Sm-EDTMP treatment. Urine was collected 48 h after injection of {sup 153}Sm-EDTMP, and whole-body images were obtained 6, 24 and 48 h post-injection. The effect of zoledronic acid on total bone uptake of {sup 153}Sm-EDTMP was measured indirectly by the cumulative activity excreted in the urine in weeks 1, 3 and 15. Biodistribution, safety, tolerability and effect on prostate-specific antigen level were also studied. The urinary excretion in week 3 divided by the urinary excretion in week 1 (baseline) times 100% was mean 98.4 {+-} 11.6% (median 96.2%). From week 1 to 15, after four zoledronic acid treatments, the mean ratio was 101.9 {+-} 10.7% (median 101.8%). Bioequivalence could be concluded by using a two-sample t test for both per-protocol (n = 13) and full-analysis sets (n = 18). Toxicity was comparable to of monotherapy with {sup 153}Sm-EDTMP. Zoledronic acid treatment does not influence {sup 153}Sm-EDTMP skeletal uptake. Combined treatment is feasible and safe. (orig.)

    Bone metastases are a common and distressing effect of cancer, being a major cause of morbidity in many patients with advanced stage cancer, in particular in breast and prostate cancer. Patients with bone metastases can experience complications known as skeletal-related events (SREs) which may cause significant debilitation and have a negative impact on quality of life and functional independence. The current recommended systemic treatment for the prevention of SREs is based on the use of bisphosphonates: ibandronate, pamidronate and zoledronic acid- the most potent one- are approved in advanced breast cancer with bone metastases, whereas only zoledronic acid is indicated in advanced prostate cancer with bone metastases. The 2011 ASCO guidelines on breast cancer, recommend initiating bisphosphonate treatment only for patients with evidence of bone destruction due to bone metastases. Denosumab, a fully human antibody that specifically targets the RANK-L, has been demonstrated in two phase III studies to be superior to zoledronic acid in preventing or delaying SREs in breast and prostate cancer and non-inferior in other solid tumours and mieloma; it's convenient subcutaneous administration and the fact that does not require dose adjustment in cases of renal impairment, make this agent an attractive new therapeutic option in patients with bone metastases. Finally, in a phase III study against placebo, denosumab significantly increased the median metastasis-free survival in high risk non-metastatic prostate cancer, arising the potential role of these bone-modifying agents in preventing or delaying the development of bone metastases.

    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

In support of studies of the natural history of bone metastases and SREs in Danish prostate and breast cancer patients, we estimated the sensitivity and specificity of hospital diagnoses for bone metastases and SREs (ie, radiation therapy to the bone, pathological or osteoporotic fractures, spinal cord compression and surgery to the bone in a nationwide medical registry in Denmark.Study design and setting: In North Jutland County, Denmark, we randomly sampled 100 patients with primary prostate cancer and 100 patients with primary breast cancer diagnoses from the National Registry of Patients (NRP, during the period January 1st, 2000 to December 31st, 2000 and followed them for up to five years after their cancer diagnosis. We used information from medical chart reviews as the reference for estimating sensitivity, and specificity of the NRP International Classification of Diseases, 10th edition (ICD-10 coding for bone metastases and SRE diagnoses. Results: For prostate cancer, the overall sensitivity of bone metastases or SRE coding in the NRP was 0.54 (95% confidence interval [CI]: 0.39–0.69, and the specificity was 0.96 (95% CI: 0.87–1.00. For breast cancer, the overall sensitivity of bone metastases or SRE coding in the NRP was 0.58 (95% CI: 0.34–0.80, and the specificity was 0.95 (95% CI: 0.88–0.99. Conclusion: We measured the validity of ICD-10 coding in the Danish NRP for bone metastases and SREs in prostate and breast cancer patients and found it has adequate sensitivity and high specificity. The NRP remains a valuable tool for clinical epidemiological studies of bone

    In patients with osteotropic primary tumours such as breast and prostate cancer, imaging treatment response of bone metastases is essential for the clinical management. After treatment of skeletal metastases, morphological changes, in particular of bone structure, occur relatively late and are difficult to quantify using conventional X-rays, CT or MRI. Early treatment response in these lesions can be assessed from functional imaging techniques such as dynamic contrast-enhanced techniques by MRI or CT and by diffusion-weighted MRI, which are quantifiable. Among the techniques within nuclear medicine, PET offers the acquisition of quantifiable parameters for response evaluation. PET, therefore, especially in combination with CT and MRI using hybrid techniques, holds great promise for early and quantifiable assessment of treatment response in bone metastases. This review summarises the classification systems and the use of imaging techniques for evaluation of treatment response and suggests parameters for the early detection and quantification of response to systemic therapy.

    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.

    The different biological features of the various major entities of thyroid cancer, e.g. papillary, follicular, poorly differentiated, anaplastic and medullary, depend to a large extent on their different metastatic spread. Papillary thyroid cancer (PTC) has a propensity for cervical lymphatic spread that occurs in 20-50 % of patients whereas distant metastasis occurs in thyroid cancer (FTC) has a marked propensity for vascular but not lymphatic invasion and 10-20 % of FTC develop distant metastases. At the time of diagnosis approximately one third of medullary thyroid cancer (MTC) cases show lymph node metastases, in 10-15 % distant metastases and 25 % develop metastases during the course of the disease. Poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC) spread via both lymphatic and vascular invasion. Thus distant metastases are relatively uncommon in DTC and when they occur, long-term stable disease is the typical clinical course. The major sites of distant metastases are the lungs and bone. Metastases to the brain, breasts, liver, kidneys, muscle and skin are relatively rare or even rare. The thyroid gland itself can be a site of metastases from a variety of other tumors. In autopsy series of patients with disseminated cancer disease, metastases to the thyroid gland were found in up to 10 % of cases. Metastases from other primary tumors to the thyroid gland have been reported in 1.4-3 % of patients who have surgery for suspected cancer of the thyroid gland. The most common primary cancers that metastasize to the thyroid gland are renal cell (48.1 %), colorectal (10.4 %), lung (8.3 %) and breast cancer (7.8 %) and surprisingly often sarcomas (4.0 %).

    Medical oncology is moving toward personalized and precision treatments. This evolution is spearheaded by ongoing discoveries on the fundamental machinery that controls tumor and hosts microenvironment biological behavior. α-Particles with their high energy and short range had long been recognized as potentially useful in the treatment of cancer. More than a century after the discovery of radium by the Curies, 223Ra dichloride is now available in the expanding armamentarium of therapies for metastatic castration-resistant prostate cancer. This advance occurs in the context of several other novel therapeutics in advanced prostate cancer that include more effective androgen receptor pathway inhibition, better chemotherapy, and immunotherapy. We present a concise review on the therapeutic use of 223Ra dichloride in this clinically important setting including excerpts on the radium history, physical properties, the alpharadin in symptomatic prostate cancer clinical trial, and practical information on its use in the clinic. It is anticipated that, with the current emergence of 223Ra as a viable form of therapy, interest in and use of α-particle therapy in the management of cancer will grow.

    Bone metastases from prostate cancer are very common. They are usually located on the axial skeleton. However, cranial bone metastases especially to the parietal bone are rare. We report a case of metastatic prostate cancer presenting with left parietal bone metastasis in a patient with no urological symptoms or signs. We should consider prostate cancer in any man above 60 years presenting unusual bone lesions.

    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

    The aim of this study was to evaluate the clinical usefulness of [{sup 11}C]choline positron emission tomography (PET)/CT in comparison with bone scintigraphy (BS) in detecting bone metastases (BM) of patients with biochemical progression after radical treatment for prostate cancer (PCa). Seventy-eight consecutive patients with biochemical progression of PCa (mean prostate-specific antigen 21.1 ng/ml, range 0.2-500.0 ng/ml) referred for both [{sup 11}C]choline PET/CT and BS for restaging purposes were retrospectively analysed. The diagnostic accuracy of [{sup 11}C]choline PET/CT and BS was assessed by using morphological imaging and/or follow-up as standards of reference. As equivocal findings were found, the accuracy analysis was performed twice, once including them as positive and once as negative. A separate analysis was also performed in hormone-resistant patients and data compared with those of patients who did not receive anti-androgenic treatment. Equivocal findings occurred in 1 of 78 (1%) cases in [{sup 11}C]choline PET/CT and in 21 of 78 (27%) cases in BS. Depending on their attribution as either positive or negative, the ranges of sensitivity, specificity, positive predictive value, negative predictive value and accuracy for [{sup 11}C]choline PET/CT were 89-89%, 98-100%, 96-100%, 94-96% and 95-96%, respectively. For BS they were 100-70%, 75-100%, 68-100%, 100-86% and 83-90%, respectively. Concordant findings between [{sup 11}C]choline PET/CT and BS occurred in 55 of 78 (71%) cases. The accuracy of [{sup 11}C]choline PET/CT did not significantly (p = 0.30) differ between hormone-resistant patients (97%) and those who did not receive anti-androgenic treatment (95%). In clinical practice, [{sup 11}C]choline PET/CT may not replace BS because of its lower sensitivity. However, for its high specificity, [{sup 11}C]choline PET/CT positive findings may accurately predict the presence of BM. Equivocal findings are more frequent in BS than [{sup 11}C]choline PET

    Full Text Available Li-Li Qu, Hai-Feng Qin, Hong-Jun Gao, Xiao-Qing Liu Department of Lung Cancer, Affiliated Hospital of Academy of Military Medical Science, Beijing, People’s Republic of China Abstract: 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.

  20. The role of radioisotopes for the palliation of bone pain from bone metastases

    Institute of Scientific and Technical Information of China (English)

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

    Gastric carcinoma is the third most common gastrointestinal (GI) malignancy after colon and pancreatic carcinoma. A Japanese study showed that the incidence of bone metastases of gastric cancer was 13.4% among autopsies. It is very rare for the primary presentation of a gastric malignancy to be with bone metastases. This case report is of a 46-year-old female patient, who presented with a thoracic vertebral wedge fracture and was subsequently found to have widespread vertebral metastatic deposits with marrow infiltration. The infiltration and suppression of marrow function was complicated by an acute bleed into the extradural space causing spinal cord compression. This case demonstrates two important features. First, that gastric cancer, although far less common than breast, kidney, thyroid, prostate and bronchial cancer, is a cause of metastases to bone. Second, it highlights the complications of bone metastases, marrow suppression, leukoerythroblastic anaemia, spinal canal haematoma and cord compression. The case is illustrated by axial and sagittal MRI slices.

    Objective: To summarize the experience of diagnosis and treatment outcomes for bone metastatic prostate cancer. Methods: A retrospective study with a total of 128 prostate cancer (Pca) was performed from 2000 to 2005, in our institute. We analyzed the clinical features and outcomes of patients with bone metastases and the data and follow-up of 63 bone metastases was collected by one registrar. Cochran Armitage trend test was used for statistic analysis and a P-value of < 0.05 was taken as statistically significant. Results: The mean age was 73 (range 55 to 87) years. The PSA level was from 0.083 ng/mL to 6462 ng/mL. Bone metastases morbidity had good relationship with PSA level. With the mean follow up of 30 (range 6 to 72) months for 52/63 (82.5%) patients, 15 (28.8%) died from Pea with a mean survival of 21 months and 1 patient with PSA less than 4 ng/mL at the time died from cerebrovascular suddenness 6 months post-treatment. Conclusion: The early effect of endocrine treatment for bone metastases is obvious, and palliative prostatectomy is satisfactory and able to improve the quality of life rapidly for patients with obstructive symptoms.

  4. The Surgical Treatment of Pelvic Bone Metastases

    Full Text Available Pelvic bone metastases are a growing concern in the field of orthopedic surgery. Patients with pelvic metastasis are individually different with different needs of treatment in order to attain the best possible quality of life despite the advanced stage of disease. A holistic collaboration among the oncologist, radiation therapist, and orthopedic surgeon is mandatory. Special attention has to be directed to osteolytic lesions in the periacetabular region as they can provoke pathological fractures and subsequent functional impairment. Different reconstruction techniques for the pelvis are available; the choice depends on the patient’s prognosis, size of the bone defect, and response of the tumor to adjuvant treatment. If all the conservative treatments are exhausted and the patient is not eligible for surgery, one of the various percutaneous ablation procedures can be considered. We propose a pelvic analogue to the treatment algorithm in long bone metastasis and a scoring system in pelvic metastasis. This algorithm aims to simplify the teamwork and to avoid under- or overtreatment of pelvic bone metastases.

    Highlights: • Spectral CT were useful for the follow-up of spinal lesions in patients with lung cancer. • Spectral CT were useful for more accurate differential diagnosis of OBMs and BIs. • 110 keV virtual monochromatic images were the optimal for providing this differentiation. - Abstract: Objectives: To evaluate the diagnostic efficacy of spectral CT for the differentiation of osteoblastic metastases (OBMs) from bone islands (BIs) in patients with lung cancer. Methods: In 94 patients with lung cancer who underwent spectral CT, focal hyperdense lesions in vertebral bodies were diagnosed as OBMs or BIs. Regions of interest were placed within each lesion to measure the mean CT value and its standard deviation (SD) on polychromatic single-energy CT (SECT) at 140 kVp and dual-energy virtual monochromatic spectral (VMS) images. The mean bone (D{sub bone(wa)}) and water densities (D{sub wa(bone)}) of each lesion were also measured. The slope (k) of the spectral curve was calculated. Independent-sample t-test was used to compare those values between OBMs and BIs. Receiver operator characteristic analysis was performed to compare the area under curve (AUC) for the differentiation of OBMs from BIs. Results: A total of 79 OBMs and 43 BIs were confirmed. The CT and SD values on SECT at 140 kVp and VMS images at 50–130 keV, k value, and D{sub bone(wa)} for OBMs were significantly lower than for BIs; D{sub wa(bone)} was significantly higher for OBMs than for BIs (p < 0.05 for all). The AUC for the SD value at 110 keV was the highest among those parameters. The optimal cut-off value for this differentiation was 68.6 HU for the SD value on VMS images at 110 keV with sensitivity of 93.0% and specificity of 93.3%. Conclusion: Spectral CT is helpful for the differentiation of OBMs from BIs in patients with lung cancer, particularly using SD of the CT value on high-energy VMS images.

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

    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

    Assessment of the response to treatment of metastases is crucial in daily oncological practice and clinical trials. For soft tissue metastases, this is done using computed tomography (CT), Magnetic Resonance Imaging (MRI) or Positron Emission Tomography (PET) using validated response evaluation criteria. Bone metastases, which frequently represent the only site of metastases, are an exception in response assessment systems, because of the nature of the fixed bony defects, their complexity, which ranges from sclerotic to osteolytic and because of the lack of sensitivity, specificity and spatial resolution of the previously available bone imaging methods, mainly bone scintigraphy. Techniques such as MRI and PET are able to detect the early infiltration of the bone marrow by cancer, and to quantify this infiltration using morphologic images, quantitative parameters and functional approaches. This paper highlights the most recent developments of MRI and PET, showing how they enable early detection of bone lesions and monitoring of their response. It reviews current knowledge, puts the different techniques into perspective, in terms of indications, strengths, weaknesses and complementarity, and finally proposes recommendations for the choice of the most adequate imaging technique.

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

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

    Objective: The purpose of this study was to assess the clinical application value of bone turnover markers in non-small-cell lung cancer (NSCLC) patients with bone metastases. Including diagnosing bone metastases, detecting bone metastatic spread. Methods: Alkaline phosphatase (AKP), β-C-terminal telopeptide of type Ⅰ collagen (β-CTx), osteocalcin (OST) and bone alkaline phosphatase (BALP) were measured in 76 patients with bone metastases from NSCLC and 44 normal people. Results: The level of AKP, β-CTx and BALP in patients with bone metastasis was significantly higher than in the normal people. Significant correlation was observed among bone turnover markers. The levels of BALP and OST were significantly correlated with the extent of bone metastasis. The patients with high-level CTx and low-level BALP had higher risk of pathologic fracture. Conclusion: In NSCLC patients with bone metastases, bone turnover markers can help to make diagnosis and evaluate the severity. It will have a wide range of use in clinical practice.

  14. Suppression of NADPH Oxidase Activity May Slow the Expansion of Osteolytic Bone Metastases

    2016-08-01

    Full Text Available Lysophosphatidic acid (LPA, generated in the microenvironment of cancer cells, can drive the proliferation, invasion, and migration of cancer cells by activating G protein-coupled LPA receptors. Moreover, in cancer cells that have metastasized to bone, LPA signaling can promote osteolysis by inducing cancer cell production of cytokines, such as IL-6 and IL-8, which can stimulate osteoblasts to secrete RANKL, a key promoter of osteoclastogenesis. Indeed, in cancers prone to metastasize to bone, LPA appears to be a major driver of the expansion of osteolytic bone metastases. Activation of NADPH oxidase has been shown to play a mediating role in the signaling pathways by which LPA, as well as RANKL, promote osteolysis. In addition, there is reason to suspect that Nox4 activation is a mediator of the feed-forward mechanism whereby release of TGF-beta from bone matrix by osteolysis promotes expression of PTHrP in cancer cells, and thereby induces further osteolysis. Hence, measures which can down-regulate NADPH oxidase activity may have potential for slowing the expansion of osteolytic bone metastases in cancer patients. Phycocyanin and high-dose statins may have utility in this regard, and could be contemplated as complements to bisphosphonates or denosumab for the prevention and control of osteolytic lesions. Ingestion of omega-3-rich flaxseed or fish oil may also have potential for controlling osteolysis in cancer patients.

    Full Text Available Osteopoikilosis is a rare benign osteosclerotic bone disorder that may be misdiagnosed as skeletal metastases. Here we describe a case of coincidental breast cancer and osteopoikilosis mimicking skeletal metastases. A 41-year-old woman underwent right modified radical mastectomy in April 2007. Twenty-eight months after initial treatment,the patient complained of bilateral knee and foot pain. Plain X-rays of the feet and knees showed multiple well-defined osteosclerotic lesions. According to the radiographic appearance, the most likely differential diagnoses included skeletal metastases from breast cancer and osteopoikilosis. A whole-body bone scintigraphy showed no increase in uptake by the sclerotic lesions, and serum lactic dehydrogenase, carcinoembryonic antigen, alkaline phosphatase and cancer antigen 15-3 were not elevated. We therefore diagnosed the patient’s skeletal lesions as osteopoikilosis. This case and ourliterature review suggest that the radiographic appearance of osteopoikilosis may mimic or mask skeletal metastases, potentially leading to misdiagnosis in patients with cancer.

    2012-11-01

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

    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.......e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM...... is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical...

    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.

    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.

(153)Samarium lexidronam ((153)Sm-EDTMP; Quadramet, Cytogen) is a radiopharmaceutical designed for deposition into bone metastases. Bone scans can identify patients that may benefit from targeted radiation therapy with (153)Sm-EDTMP. As an unsealed source of radiation therapy, (153)Sm-EDTMP is simple to administer: 1 mCi/kg is given in a similar fashion to a bone scan injection ((99m)Tc-MDP bone scan injection is given at 0.2-0.35 mCi/kg. Therefore, both are administered intravenously. However, the radiation-absorbed dose and radiopharmaceutical energy are different). Nevertheless, despite simplicity of administration, (153)Sm-EDTMP is underutilized for improving cancer pain in the skeleton. Repeated cycles and combined treatment with other modalities such as bisphosphonates, chemotherapy and/or external beam radiation are possible. (153)Sm-EDTMP combined with bisphosphonates, chemotherapy and/or radiation may provide better palliation of bone metastases and also in bone-forming tumors (osteosarcoma). Encouraging experience using high-dose (153)Sm-EDTMP for total marrow irradiation in hematologic malignancies involving the bones (e.g., myeloma or acute leukemia) is also reviewed.

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

    Between June 1973 and November 1980, 1,171 patients with metastatic breast cancer were treated with various doxorubicin-containing regimens at our institution (M.D. Anderson Hospital and Tumor Institute, Houston). Retrospective analysis of all 233 cases (20%) with liver metastases was done to correlate various clinical and biochemical characteristics with response to treatment, survival, and causes of death. A similar analysis was performed for 58 consecutive patients with liver metastases treated at this hospital between December 1955 and December 1957 with hormone therapy or single-agent chemotherapy. Objective responses were observed in 132 of 233 patients (57%) treated with combination chemotherapy. The median survival was 14 months in the 1970s and 5 months in the 1950s. Among patients who had liver metastases at the time of initial diagnosis of breast cancer, survival was longer for the group treated with combination chemotherapy. All cases were classified according to the number of organ sites involved by metastases. Patients with only liver metastases, or liver plus bone lesions had the longest survival. Other clinical and biochemical factors that correlated significantly with longer survival were: no prior chemotherapy, performance status of 1 to 2, absence of ascites, normal bilirubin and lactic dehydrogenase (LDH), SGOT less than or equal to 2 times normal and albumin greater than 4.5 g/dL. The main cause of death was multiorgan failure, with only 20% of patients dying of liver failure. The present study shows that the presence of liver metastases in breast cancer is not by itself an ominous factor. Most patients respond to therapy, and significant palliation with extended survival is possible for several prognostic subgroups. Further improvement in length and quality of survival is expected with earlier diagnosis.

    Cancer-associated muscle weakness is poorly understood and there is no effective treatment. Here, we find that seven different mouse models of human osteolytic bone metastases, representing breast, lung and prostate cancers, as well as multiple myeloma exhibited impaired muscle function, implicating a role for the tumor-bone microenvironment in cancer-associated muscle weakness. We found that TGF-β, released from the bone surface as a result of metastasis-induced bone destruction upregulated NADPH oxidase 4 (Nox4), resulting in elevated oxidization of skeletal muscle proteins, including the ryanodine receptor/calcium (Ca2+) release channel (RyR1). The oxidized RyR1 channels leaked Ca2+, resulting in lower intracellular signaling required for proper muscle contraction. We found that inhibiting RyR1 leak, TGF-β signaling, TGF-β release from bone or Nox4 all improved muscle function in mice with MDA-MB-231 bone metastases. Humans with breast cancer- or lung cancer-associated bone metastases also had oxidized skeletal muscle RyR1 that is not seen in normal muscle. Similarly, skeletal muscle weakness, higher levels of Nox4 protein and Nox4 binding to RyR1, and oxidation of RyR1 were present in a mouse model of Camurati-Engelmann disease, a non-malignant metabolic bone disorder associated with increased TGF-β activity. Thus, metastasis-induced TGF-β release from bone contributes to muscle weakness by decreasing Ca2+-induced muscle force production. PMID:26457758

    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 %.

    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.

    2013-10-05

    Breast cancer represents the second most frequent cause of brain metastases. Treatment planning should consider several tumor and patient factors to estimate prognosis based on the Karnofsky Performance Status (KPS), age, extent of extra-cerebral disease as well as genetic subtype. When systemic disease is under control patients with up to three metastases qualify for local therapy, such as surgical excision or stereotactic radiotherapy. After the local treatment the addition of whole brain radiation therapy may be postponed until disease progression in the brain is observed and overall survival will not be compromised. Asymptomatic brain metastases may be first approached with a systemic treatment to which the primary tumor is considered to be sensitive.

    To evaluate the reproducibility of the combination of hybrid PET/MRI and the {sup 68}Ga-PSMA-11 tracer in depicting lymph node (LN) and bone metastases of prostate cancer (PC) in comparison with that of PET/CT. A retrospective analysis of 26 patients who were subjected to {sup 68}Ga-PSMA PET/CT{sub low-dose} (1 h after injection) followed by PET/MRI (3 h after injection) was performed. MRI sequences included T1-w native, T1-w contrast-enhanced, T2-w fat-saturated and diffusion-weighted sequences (DWI{sub b800}). Discordant PET-positive and morphological findings were evaluated. Standardized uptake values (SUV) of PET-positive LNs and bone lesions were quantified and their morphological size and conspicuity determined. Comparing the PET components, the proportion of discordant PSMA-positive suspicious findings was very low (98.5 % of 64 LNs concordant, 100 % of 28 bone lesions concordant). Two PET-positive bone metastases could not be confirmed morphologically using CT{sub low-dose}, but could be confirmed using MRI. In 12 of 20 patients, 47 PET-positive LNs (71.9 %) were smaller than 1 cm in short axis diameter. There were significant linear correlations between PET/MRI SUVs and PET/CT SUVs in the 64 LN metastases (p < 0.0001) and in the 28 osseous metastases (p < 0.0001) for SUV{sub mean} and SUV{sub max}, respectively. The LN SUVs were significantly higher on PET/MRI than on PET/CT (p{sub SUVmax} < 0.0001; p{sub SUVmean} < 0.0001) but there was no significant difference between the bone lesion SUVs (p{sub SUVmax} = 0.495; p{sub SUVmean} = 0.381). Visibility of LNs was significantly higher on MRI using the T1-w contrast-enhanced fat-saturated sequence (p = 0.013), the T2-w fat-saturated sequence (p < 0.0001) and the DWI sequence (p < 0.0001) compared with CT{sub low-dose}. For bone lesions, only the overall conspicuity was higher on MRI compared with CT{sub low-dose} (p < 0.006). Nodal and osseous metastases of PC are accurately and reliably depicted by hybrid PET

    Radiotherapy for bone metastases represents an important part of daily practice in our departments of radiotherapy. Majority of treatments deliver either one fraction (6 to 10 Gy) or multi-fractions mainly using 30 Gy in ten fractions. In the past decade, several randomized trials aimed to determine the optimal scheme of radiotherapy in this setting. In the present review, the efficacy of radiotherapy on bone metastases will be evaluated using the following parameters: the partial or complete responses on pain, the reduction of antalgic intake, bone re-calcification, and need for reirradiation. Other parameters must also be considered, such as the primary site, number of metastasis, performance status, overall prognosis and side effects of radiotherapy. (authors)

    Purpose: Clinical pathways are an important tool used to manage the quality in health care by standardizing processes. This study evaluated the impact of the implementation of a peer-reviewed clinical pathway in a large, integrated National Cancer Institute-Designated Comprehensive Cancer Center Network. Methods: In 2003, we implemented a clinical pathway for the management of bone metastases with palliative radiation therapy. In 2009, we required the entry of management decisions into an online tool that records pathway choices. The pathway specified 1 or 5 fractions for symptomatic bone metastases with the option of 10-14 fractions for certain clinical situations. The data were obtained from 13 integrated sites (3 central academic, 10 community locations) from 2003 through 2010. Results: In this study, 7905 sites were treated with 64% of courses delivered in community practice and 36% in academic locations. Academic practices were more likely than community practices to treat with 1-5 fractions (63% vs. 23%; p < 0.0001). The number of delivered fractions decreased gradually from 2003 to 2010 for both academic and community practices (p < 0.0001); however, greater numbers of fractions were selected more often in community practices (p < 0.0001). Using multivariate logistic regression, we found that a significantly greater selection of 1-5 fractions developed after implementation online pathway monitoring (2009) with an odds ratio of 1.2 (confidence interval, 1.1-1.4) for community and 1.3 (confidence interval, 1.1-1.6) for academic practices. The mean number of fractions also decreased after online peer review from 6.3 to 6.0 for academic (p = 0.07) and 9.4 to 9.0 for community practices (p < 0.0001). Conclusion: This is one of the first studies to examine the efficacy of a clinical pathway for radiation oncology in an integrated cancer network. Clinical pathway implementation appears to be effective in changing patterns of care, particularly with online clinical

    Full Text Available Bone is the preferred metastasis site of advanced prostate cancer (PCa. Using an in vivo murine model of human PCa cell metastasis to bone, we noted that the majority of animals that develop skeletal metastasis have either spinal lesions or lesions in the bones of the hindlimb. Much less frequently, lesions develop in the bones of the forelimb. We therefore speculated whether the environment of the forelimb bones is not permissive for the growth of PCa. Consequently, data on tumor prevalence were normalized to account for the number of PCa cells arriving after intravascular injection, marrow cellularity, and number of hematopoietic stem cell niches. None of these factors were able to account for the observed differences in tumor prevalence. An analysis of differential gene and protein levels identified that growth arrest specific-6 (GAS6 levels were significantly greater in the forelimb versus hindlimb bone marrow. When murine RM1 cells were implanted into subcutaneous spaces in immune competent animals, tumor growth in the GAS6-/- animals was greater than in GAS6+/+ wild-type animals. In an osseous environment, the human PC3 cell line grew significantly better in vertebral body transplants (vossicles derived from GAS6-/- animals than in vossicles derived from GAS6+/+ animals. Together, these data suggest that the differences in tumor prevalence after intravascular inoculation are a useful model to study the molecular basis of tumor dormancy. Importantly, these data suggest that therapeutic manipulation of GAS6 levels may prove useful as a therapy for metastatic disease.

    Biochemically failing metastatic prostate cancer is typically treated with androgen ablation. However, due to the emergence of castration-resistant cells that can survive in low androgen concentrations, such therapy eventually fails. Here, we develop a partial differential equation model of the growth and response to treatment of prostate cancer that has metastasized to the bone. Existence and uniqueness results are derived for the resulting free boundary problem. In particular, existence and uniqueness of solutions for all time are proven for the radially symmetric case. Finally, numerical simulations of a tumor growing in 2-dimensions with radial symmetry are carried in order to evaluate the therapeutic potential of different treatment strategies. These simulations are able to reproduce a variety of clinically observed responses to treatment, and suggest treatment strategies that may result in tumor remission, underscoring our model's potential to make a significant contribution in the field of prostate cancer therapeutics.

    Objective To investigate the added diagnostic value of SPECT/CT imaging over routine planar whole-body bone scintigraphy (WBBS) for bone metastases from lung cancer. Methods One hundred and forty-six patients with lung cancer, confirmed by pathological examination, underwent routine 99Tcm-MDP (1110 MBq) WBBS, followed by SPECT/CT over the regions with indeterminate findings on WBBS. Both WBBS and bone SPECT/CT images were interpreted by two experienced nuclear medicine physicians in consensus as the positive, negative or uncertain bone metastases. The final diagnosis was comfirmed by pathology or clinical follow-up. x2 test was used to compare the differences between the two imaging methods. Results Finally, 45 patients were diagnosed as positive bone metastases and the other 101 as negative. The diagnostic sensitivity of bone SPECT/CT for bone metastases from lung cancer was 93.3%(42/45), singnificantly higher than that of WBBS (64.4%, 29/45) (x2 = 19.944, P<0.05). The diagnostic accuracy of bone SPECT/CT was 89.7% ( 131/146), much higher than that of WBBS (44.5%,65/146) ( x2 = 69. 598,P < 0.05). The uncertain and incorrect diagnostic rates of bone SPECT/CT and WBBS were 10.3% ( 15/146, raging from 5.3% to 15.2% with 95% confidence interval (CI) ) and 55.5% (81/146, raging from 47. 4% to 63.5% with95% CI), respectively.

    In the human body, metastases are the most frequently found bone tumors. We can distinguish between lytic, blastic and mixed forms. The authors recall the radiologic aspects of these last ones, and describe even so the imagery with magnetic resonance. they also recall that major differences between a compressive benign osteoporotic tumor and a malignant one remains an every day diagnostic problem. Finally, magnetic resonance is proven to be a better diagnostic tool in comparison with the radiologic standard examination. (author)

    Objective In non-small cell lung cancer (NSCLC), metastatic bone involvement is usually assessed using conventional {sup 99m}Tc-HMDP bone scintigraphy, which has a high sensitivity but a poor specificity. The purpose of this study was to assess the usefulness of the {sup 99m}Tc-D scintigraphy for the detection of malignant bone metastases in patients with NSCLC stage III or IV and to compare these results with {sup 99m}Tc-HMDP bone scan findings. Methods Nineteen patients (13 M and 6 F, mean age 59 years) with proven NSCLC, suspected to have stage III or IV were enrolled prospectively. All patients underwent whole body {sup 99m}Tc-HMDP and {sup 99m}Tc-D scintigraphy to detect bone metastases within a mean interval of 14 days. Each focal uptake of {sup 99m}Tc-D or {sup 99m}Tc-HMDP was considered benign or malignant, leading to positive or negative diagnosis for bone involvement. The final diagnosis of bone metastases was established by a lung specialist, on the basis of additional imaging modalities and of 12 months follow-up. Results Twelve bone lesions were identified by {sup 99m}Tc-D scintigraphy, 10 were classified as bone metastases and two were classified as inflammatory bone lesions. Four patients were metastatic. Fifty eight bone lesions were detected by {sup 99m}Tc-HMDP scintigraphy, 26 of whom were considered malignant, eight patients were thus considered metastatic. Thereby, the two nuclear medicine modalities were concordant for 13 patients, that is 68% of cases and were discordant for six patients, representing 32% of cases. Diagnostic sensitivity, specificity and accuracy of depreotide scintigraphy and {sup 99m}Tc-HMDP bone scintigraphy were 75% for both, 93.3 and 73.3%, and 89.5 and 73.3% respectively. Conclusion Our data suggest that depreotide scintigraphy with the same sensitivity, a better accuracy and specificity than those of {sup 99m}Tc-HMDP bone scan can detect metastatic bone lesions in patients with NSCLC suspected to have stage III or IV

    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

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

    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.

    Distant metastases of differentiated thyroid cancer are unusual; lung and bones are the most frequently affected sites. Soft tissue metastases (STM) are extremely rare. We describe two cases of patients with differentiated thyroid cancer metastasizing to soft tissues. Both patients had widespread metastatic disease; clinically asymptomatic soft tissue metastases were found by 18-Fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F FDG PET-CT), and confirmed by cytological and/or histopathological studies. These findings underscore the ability of {sup 18}F FDG PET-CT in accurately assessing the extent of the disease, as well as the utility of the method to evaluate regions of the body that are not routinely explored.

    Objective:To analyze the clinical course and treatment result of lung metastases from breast cancer. Method:122 cases with lung metastases from breast cancer were treated with chemotherapy or chemotherapy plus endocrine therapy, response was assessed according to WHO criteria and survival rate estimated using the life Table. Results: The median time from initial treatment of primary tumor to lung metastases was 22 months. Sites of common consecutive metastases were lung, liver and bone. The overall response rate was 48% with a CR rate of 15%. Compared to non- DDP- encompassing regimen, the CR rate was higher in DDP-based chemotherapy (7%versus 21%, P<0.05) with a longer median survival time (MST). The PR rate was higher in regimens containing anthracycline (48%) than in those without anthracycline (20%, P<0.01). The response rate was similar between chemotherapy and chemotherapy plus endocrine therapy (P>0.05). No difference in MST was observed between patients receiving anthracycline-and non-anthracyclineencompassing regimens. The 1-, 3-, 5-, and 10-year survival rate was 77%, 22 %, 11%, and 10%, respectively.Conclusion: Size of primary tumor, the length of diseasefree interval, the number of lung metastases may provide additional information for predicting patients survival after treatment of lung metastases. Combination chemotherapy, especially DDP-based chemotherapy may prolong survival time of patients with lung metastases from breast cancer.

Results: Twenty patients were enrolled in this study, twelve patients in zoledronic acid group and eight in pamidronate group. Zoledronic acid and pamidronate significantly palliated pain. Pain scores were significantly lower at end-point after Zoledronic acid or pamidronate infusion(5.92 vs 3.25,P<0.01;6.13 vs 4.38, P<0.01, respectively). The mean CSC level decreased significantly after Zoledronic acid or pamidronate infusion from 12.86 to 10.28mg/dl and 13.19 to 10.36mg/dl respectively. The CSC effective rate was about 90% at 14 days after infusion in two groups. There was no statistical significance for all primary efficacy parameters in zoledronic acid group compared with pamidronate group. An adverse reaction was mild fever after pamidronate infusion and then completely reversible. Conclusion: Zoledronic acid and pamidronate disodium were well tolerated and effective for bone metastases and hypercalcemia of malignancy in advanced solid tumor.

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

    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

    ABSTRACT The aim of this study was to reduce barriers that prevent implementation of evidence-based recommendations about single-fraction palliative radiotherapy (PRT) and to demonstrate that single-fraction PRT yields similar outcomes as long-course treatment (≥10 fractions) in patients with bone metastases from breast cancer. This retrospective study (2007–2014) included 118 Norwegian female patients. All patients received guideline-conform systemic therapy including bone-targeting agents. Median survival was 12.7 months. Long-course PRT was prescribed in 60% of patients, while 21% had PRT with a single fraction of 8 Gy to at least one target. Reirradiation rate was not significantly higher after 8 Gy (9%, compared to 5% after long-course PRT and 6% after 4 Gy x5). Patients with favorable baseline characteristics such as younger age and good performance status (PS) were significantly more likely to receive long-course PRT. Biological subtype and comorbidity did not correlate with fractionation. Prognosis was influenced by biological subtype, extra-skeletal disease extent, severe anemia and abnormal CRP. The limited need for reirradiation after single fraction PRT might encourage physicians to prescribe this convenient regimen, which would improve resource utilization. Even patients with PS3 had a median survival of 3 months, which indicates that they could experience worthwhile clinical benefit.

    Full Text Available Background. Metastasis is a crucial endpoint for patients with prostate cancer (PCa, but currently lacks a validated claims-based algorithm for detection. Objective. To develop an algorithm using ICD-9 codes to facilitate accurate reporting of PCa metastases. Methods. Medical records from 300 men hospitalized at Robert Wood Johnson University Hospital for PCa were reviewed. Using the presence of metastatic PCa on chart review as the gold standard, two algorithms to detect metastases were compared. Algorithm A used ICD-9 codes 198.5 (bone metastases, 197.0 (lung metastases, 197.7 (liver metastases, or 198.3 (brain and spinal cord metastases to detect metastases, while algorithm B used only 198.5. Sensitivity, specificity, positive predictive value (PPV, and negative predictive value (NPV for the two algorithms were determined. Kappa statistics were used to measure agreement rates between claim data and chart review. Results. Algorithm A demonstrated a sensitivity, specificity, PPV, and NPV of 95%, 100%, 100%, and 98.7%, respectively. Corresponding numbers for algorithm B were 90%, 100%, 100%, and 97.5%, respectively. The agreement rate is 96.8% for algorithm A and 93.5% for algorithm B. Conclusions. Using ICD-9 codes 198.5, 197.0, 197.7, or 198.3 in detecting the presence of PCa metastases offers a high sensitivity, specificity, PPV, and NPV value.

    Full Text Available Abstract Background Foetal antigen 2 (FA-2, first isolated in the amniotic fluid, was shown to be the circulating form of the aminopropeptide of the alpha 1 chain of procollagen type I. Serum concentrations of FA-2 appeared to be elevated in a number of disorders of bone metabolism. This paper is the first report of its role as a marker of bone metabolism in metastatic breast cancer. Methods Serum FA-2 concentrations were measured by radioimmunoassay in 153 women with different stages of breast cancer and in 34 normal controls. Results Serum FA-2 was significantly elevated in women with bony metastases (p Conclusions FA-2 is a promising blood marker of bone metabolism. Further studies to delineate its role in the diagnosis and management of bony metastases from breast cancer are required.

    Context • Researchers have reported improved survival rates for patients with cancer when 10-75 g of vitamin C (ascorbic acid, or AA) is administered intravenously. AA exhibits a cytotoxic effect upon entering a cancer cell. Objective • The current study examined the benefits of intravenous administration of AA in treatment of bone metastases. Design • The study was a pilot study. Setting • The study was performed at Bezmialem Vakif University Medical Facility (BVUMF) in the Department of Radiation Oncology, from 2010-2012. Participants • Participants were 11 cancer patients with bone metastases who were unresponsive to standard cancer treatments and who experienced the following issues after receiving a total of 3000 cGy of radiotherapy: (1) intensifying pain, (2) an increase in metastatic sites, and/or (3) a deterioration in general health. Intervention • The 11 patients received 2.5 g of AA in a physiological saline solution, within 1 h period with 3-10 applications following at 1-wk intervals. Outcome Measures • The ECOG Performance Scale and Visual Analog Scale were used to assess performance and pain. Results • Among the participants administered AA, the mean reduction in pain was 55%, and the median survival time was 10 mo. Participants experienced a 40% grade-I gastrointestinal toxicity and a 30% urinary toxicity. Conclusions • Given the study's results, the current research team found considerable encouragement in the use of AA after radiotherapy for treatment of patients with bone metastases. Toxicity was in the acceptable range for AA treatment.

    Vertebral metastases are a common manifestation of many cancers, potentially leading to vertebral collapse and neurological complications. Conventional treatment often involves percutaneous vertebroplasty/kyphoplasty followed by external beam radiation therapy. As a more convenient alternative, we have introduced radioactive bone cement, i.e. bone cement incorporating a radionuclide. In this study, we used a previously developed Monte Carlo radiation transport modeling method to evaluate dose distributions from phosphorus-32 radioactive cement in simulated clinical scenarios. Isodose curves were generally concentric about the surface of bone cement injected into cadaveric vertebrae, indicating that dose distributions are relatively predictable, thus facilitating treatment planning (cement formulation and dosimetry method are patent pending). Model results indicated that a therapeutic dose could be delivered to tumor/bone within ∼4 mm of the cement surface while maintaining a safe dose to radiosensitive tissue beyond this distance. This therapeutic range should be sufficient to treat target volumes within the vertebral body when tumor ablation or other techniques are used to create a cavity into which the radioactive cement can be injected. With further development, treating spinal metastases with radioactive bone cement may become a clinically useful and convenient alternative to the conventional two-step approach of percutaneous strength restoration followed by radiotherapy.

    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

    Aim: To assess and compare the diagnostic accuracy of whole-body magnetic resonance imaging (MRI) and bone scintigraphy in the detection of metastases to bone. Material and methods: Forty randomly selected patients with known malignant tumours were prospectively studied using bone scintigraphy and whole-body MRI. Two patients were excluded. Symptoms of bone metastasis were present in 29 (76%) patients and absent in nine (24%). Findings were classified into four categories according to the probability of bone metastasis: (1) negative, (2) probably negative, (3) probably positive, and (4) positive. Diagnostic accuracy was determined according to the area under the receiver operating characteristic (ROC) curve. The definitive diagnosis was reached using other imaging techniques, biopsy, or 12 months clinical follow-up. Results: Metastases were present in 18 patients. The sensitivity, specificity, and diagnostic accuracy were 94, 90, and 92%, respectively, for whole-body MRI and 72, 75, and 74%, respectively, for bone scintigraphy. Diagnostic accuracy measured by the area under the ROC curve was significantly higher for whole-body MRI (96%) than for bone scintigraphy (77%; p<0.05). Interobserver agreement measured by the kappa index was significantly higher for whole-body MRI (0.895) than for bone scintigraphy (0.524; p<0.05). Whole-body MRI detected lesions in tissues other than bone in 17 (45%) patients. Conclusions: Whole-body MRI is more accurate and more objective than bone scintigraphy for the detection of bone metastases. Whole-body MRI can also detect lesions in tissues other than bone.

    The relationship between spinal metastases diagnosed by plain-film, bone scintigraphy, and MR imaging and biological characteristics in 26 patients with breast cancer was investigated retrospectively. It was found that bone scintigraphy is useful for detecting metastases in case with slow-growing tumors determined by DNA polymerase {alpha} or with estrogen-receptor (ER) positivity. In contrast, cases with rapidly growing tumors showed false-negative plain-film or bone scintigraphy results, including cases with ER-negative tumors or DNA polymerase {alpha} of more than 20%. MR imaging was found to be highly sensitive in detecting spinal metastases even in aggressive cases. MR imaging was found to have greater reliability in detecting spinal metastases of breast cancer compared to bone scintigraphy. In conclusion, it may be important to consider the degree of malignancy of each case with spinal metastases of breast cancer in evaluating imaging diagnosis. (author).

    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.

    Background: Brain metastases (BM) are frequently diagnosed in patients with HER-2-positive metastatic breast cancer; in addition, an increasing incidence was reported for triple-negative tumours. We aimed to compare brain metastases free survival (BMFS) of breast cancer subtypes in patients treated between 1996 until 2010. Methods: Brain metastases free survival was measured as the interval from diagnosis of extracranial breast cancer metastases until diagnosis of BM. HER-2 status was analysed by immunohistochemistry and reanalysed by fluorescent in situ hybridisation if a score of 2+ was gained. Oestrogen-receptor (ER) and progesterone-receptor (PgR) status was analysed by immunohistochemistry. Brain metastases free survival curves were estimated with the Kaplan–Meier method and compared with the log-rank test. Results: Data of 213 patients (46 luminal/124 HER-2/43 triple-negative subtype) with BM from breast cancer were available for the analysis. Brain metastases free survival differed significantly between breast cancer subtypes. Median BMFS in triple-negative tumours was 14 months (95% CI: 11.34–16.66) compared with 18 months (95% CI: 14.46–21.54) in HER-2-positive tumours (P=0.001) and 34 months (95% CI: 23.71–44.29) in luminal tumours (P=0.001), respectively. In HER-2-positive patients, co-positivity for ER and HER-2 prolonged BMFS (26 vs 15 m; P=0.033); in luminal tumours, co-expression of ER and PgR was not significantly associated with BMFS. Brain metastases free survival in patients with lung metastases was significantly shorter (17 vs 21 months; P=0.014). Conclusion: Brain metastases free survival in triple-negative breast cancer, as well as in HER-2-positive/ER-negative, is significantly shorter compared with HER-2/ER co-positive or luminal tumours, mirroring the aggressiveness of these breast cancer subtypes.

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

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

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

  8. Cancer Cell Colonisation in the Bone Microenvironment

    2016-10-01

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

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

    Lymph node metastases are important determinants in the prognosis of primary colorectal cancer. Although it has been established that enlarged, palpable lymph nodes contain metastases in less than half of the cases, no definitive data concerning the incidence of metastases in lymph nodes measuring 5 mm or less are available. We treated the surgical specimens of 52 consecutive patients who had colon cancer with a lymph node clearance technique at the Roswell Park Memorial Institute, Buffalo. We found 2699 lymph nodes in the 52 specimens, with a mean of 52 lymph nodes per specimen (range, five to 151). Sixty-four lymph nodes were found with metastases in 21 (40%) of the 52 patients. Fifty-nine of 64 of the lymph nodes were reexamined and remeasured. Thirty-nine lymph node metastases measured less than 5 mm, 13 were between 5 and 10 mm, and eight were larger than 10 mm. We concluded that lymph node metastases in colon cancer occur most frequently in lymph nodes measuring less than 5 mm (small lymph nodes). The use of lymph node clearing techniques in surgical specimens improves detection of small lymph node metastases and thereby diminishes understaging.

    2014-02-01

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

    2011-11-01

    Radiological and nuclear medicine imaging modalities used for assessing bone metastases treatment response include plain and digitalised radiography (XR), skeletal scintigraphy (SS), dual-energy X-ray absorptiometry (DEXA), computed tomography (CT), magnetic resonance imaging (MRI), [(18)F] fluorodeoxyglucose positron emission tomography (FDG-PET) and PET/CT. Here we discuss the advantages and disadvantages of these assessment modalities as evident through different clinical trials. Additionally, we present the more established response criteria of the International Union Against Cancer and the World Health Organization and compare them with newer MD Anderson criteria. Even though serial XR and SS have been used to assess the therapeutic response for decades, several months are required before changes are evident. Newer techniques, such as MRI or PET, may allow an earlier evaluation of response that may be quantified through monitoring changes in signal intensity and standard uptake value, respectively. Moreover, the application of PET/CT, which can follow both morphological and metabolic changes, has yielded interesting and promising results that give a new insight into the natural history of metastatic bone disease. However, only a few studies have investigated the application of these newer techniques and further clinical trials are needed to corroborate their promising results and establish the most suitable imaging parameters and evaluation time points. Last, but not least, there is an absolute need to adopt uniform response criteria for bone metastases through an international consensus in order to better assess treatment response in terms of accuracy and objectivity.

    Leptomeningeal disease (LMD) is a highly aggressive and usually rapidly fatal condition. The purpose of this study is to identify clinical factors that can serve to predict for LMD at the time of stereotactic radiosurgery (SRS) for brain metastases from breast carcinoma. We conducted a retrospective review of patients with brain metastases from breast cancer treated with SRS from 1995 to 2014 at our institution. Clinical, radiographic, and dosimetric data were collected. LMD was diagnosed by cerebrospinal fluid (CSF) cytology or MRI demonstrating CSF seeding. Comparative statistical analyses were conducted using Cox proportional hazards regression, binary logistic regression, and/or log-rank test. 126 patients met inclusion criteria. Eighteen patients (14 %) developed LMD following SRS. From the time of SRS, the actuarial rate of LMD at 12 months from diagnosis of brain metastasis was 9 % (11 patients). Active disease in the chest at the time of SRS was associated with development of LMD (p = 0.038). Factors including receptor status, tumor size, number of intra-axial tumors, cystic tumor morphology, prior WBRT, active bone metastases, and active liver metastases were not significantly associated with the development of LMD. In patients with brain metastasis from breast cancer that undergo SRS, there is a relatively low rate of LMD. We found that while tumor hormonal status, bone metastases, and hepatic metastases were not associated with the development of LMD, active lung metastases at SRS was associated with LMD. Further research may help to delineate a causative relationship between metastatic lung disease and LMD.

  17. 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.

    Purpose: This study demonstrates a methodology for tracking changes in metastatic bone disease using trajectories in material basis space in serial dual energy computed tomography (DECT) studies. Methods: This study includes patients with bone metastases from breast cancer that had clinical surveillance CT scans using a General Electric CT750HD in dual energy mode. A radiologist defined regions-of-interested (ROI) for bone metastasis, normal bone, and marrow across the serial DECT scans. Our approach employs a Radon transform to forward-projection the basis images, namely, water and iodine, into sinogram space. This data is then repartitioned into fat/bone and effective density/Z image pairs using assumed energy spectrums for the x-ray energies. This approach both helps remove negative material densities and avoids adding spectrum-hardening artifacts. These new basis data sets were then reconstructed via filtered back-projection to create new material basis pair images. The trajectories of these pairs were then plotted in the new basis space providing a means to both visualize and quantitatively measure changes in the material properties of the tumors. Results: ROI containing radiologist defined metastatic bone disease showed well-defined trajectories in both fat/bone and effective density/Z space. ROI that contained radiologist defined normal bone and marrow did not exhibit any discernible trajectories and were stable from scan to scan. Conclusions: The preliminary results show that changes in material composition and effective density/Z image pairs were seen primarily in metastasis and not in normal tissue. This study indicates that by using routine clinical DECT it may be possible to monitor therapy response of bone metastases because healing or worsening bone metastases change material composition of bone. Additional studies are needed to further validate these results and to test for their correlation with outcome.

In an attempt to improve the sensitivity of registry-based identification of metastases from prostate cancer, we tested a series of algorithms, combining elevated prostate-specific antigen (PSA levels, use of antiresorptive therapy, and performed bone scintigraphy. Patients and methods: We randomly selected 212 men diagnosed with prostate cancer in 2005–2010 in the Central Denmark Region with prespecified PSA values, antiresorptive therapy, and bone scintigraphy who did not have a registry-based diagnostic code indicating presence of distant metastases. We defined three candidate algorithms for bone metastases: 1 PSA >50 µg/L and bone scintigraphy, 2 PSA >50 µg/L and antiresorptive therapy, and 3 PSA ≤50 µg/L with antiresorptive therapy or bone scintigraphy. An algorithm for distant metastasis site other than bone was defined as PSA >50 µg/L alone. Medical chart review was used as the reference standard to establish the presence or absence of metastases. Validity was expressed as a positive predictive value (PPV or a negative predictive value, based on whether the algorithms correctly classified metastases compared with the reference standard. Results: We identified 113 men with evidence of metastases according to the candidate algorithms, and 99 men without evidence of metastases according to the candidate algorithm. The PPVs of PSA >50 µg/L were 0.10 (95% confidence interval [CI] 0.04–0.19 for bone metastases and 0.14 (95% CI 0.07–0.24 for nonbone metastases, regardless of receipt of antiresorptive

    Receptor activator of NFκB ligand (RANKL), RANK, and osteoprotegerin (OPG) represent the key regulators of bone metabolism both in normal and pathological conditions, including bone metastases. To our knowledge, no previous studies investigated and compared RANK expression in primary tumors and in bone metastases from the same patient. We retrospectively examined RANK expression by immunohistochemistry in 74 bone metastases tissues from solid tumors, mostly breast, colorectal, renal, lung, and prostate cancer. For 40 cases, tissue from the corresponding primary tumor was also analyzed. Sixty-six (89%) of the 74 bone metastases were RANK-positive and, among these, 40 (59.5%) showed more than 50% of positive tumor cells. The median percentage of RANK-positive cells was 60% in primary tumors and metastases, without any statistically significant difference between the two groups (P=0.194). The same percentage was obtained by considering only cases with availability of samples both from primary and metastasis. Our study shows that RANK is expressed by solid tumors, with high concordance between bone metastasis and corresponding primary tumor. These data highlight the central role of RANK/RANKL/OPG pathway as potential therapeutic target not only in bone metastasis management, but also in the adjuvant setting.

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

    There is controversy surrounding the optimal radiotherapy dose-fractionation for retreatment of painful bone metastases. Two commonly used regimens are 8 Gy in a single-fraction or 20 Gy in five or eight fractions. Randomized evidence, including the NCIC SC.20 randomized clinical trial, has failed to standardize clinical practice. Practitioners who use single-fraction regimens cite patient convenience, fewer acute adverse effects, and better cost-effectiveness. Practitioners who prefer multiple fractions raise questions about the interpretation of data that justifies single-fraction treatment, and the possibility that single-fraction treatment may provide inferior pain relief. Given this clinical controversy, should single-fraction irradiation be standard in retreatment of uncomplicated bone metastases? In this article, two teams debate both sides of the argument with commentary to summarize the relevant issues. The conclusion from the debate is that the "standard" treatment should be individualized to the patient with shared-decision making between the oncologist, patient and family members. In a cancer patient with poor performance status and short life expectancy, single-fraction repeat radiotherapy may be preferred; in a patient with a prolonged disease course, perhaps multiple fraction retreatments would be preferred. The choice between different fractionation schemes depends on an assessment of individual patient factors, tumour factors and unique patient circumstances.

    The prevalence of thyroid metastases in colorectal cancer (CRC) patients is unknown. We retrieved the records of all patients with CRC and pathologically proved thyroid metastasis for the period 1993-2004. Among 5,862 consecutive patients with CRC, 6 (0.1%) were diagnosed with thyroid metastases, a median of 61 months after the diagnosis of primary tumour, and a median of 19 months after the last surgical resection or radiofrequency ablation of other metastases (which were present in all cases). Signs and symptoms, when present (n=3), consisted of cervical pain, cervical adenopathy, goitre, dysphagia, and/or dysphonia. In other cases, the diagnosis was made by positron emission tomography scanning. Thyroidectomy was performed in the 5 patients with isolated thyroid metastases, with cervical lymph node dissection being required in all cases. The only patient treated conservatively because of concomitant liver and lung metastases developed life-threatening dyspnoea, which required emergent tracheal stenting. Median overall survival was 77 months, 58 months, and 12 months after the diagnosis of primary CRC, initial metastases, and thyroid metastasis, respectively. It is concluded that thyroid metastases are rare and occur late in the course of CRC. Thyroidectomy (with cervical lymph node dissection) may result in prevention or improvement of life-threatening symptoms and prolonged survival.

  10. Review of Animal Models of Prostate Cancer Bone Metastasis

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

    Objective:To study the clinical value of determination of serum procollagen I N-terminal propeptide (PINP), pro-collagen I carboxy-terminal propeptide (PICP) and carboxyterminal telopeptide of type I collagen (ICTP) contents in cancer patients with bone metastases for diagnosis . Methods- Serum PINP, PICP and ICTP contents were measured in 41 patients with bone metastases and 39 controls without bone metastases. The patients with bone metastases consisted of Group A, Group B and Group C. The comparison of bone turnovers among patients with different bone loads were analyzed. Results.- Serum PICP, ICTP contents was significantly greater in patients with bone metastases than without bone metastases(P<0. 01).

    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.)

    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 {sup 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 {sup 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

    Full Text Available Abstract Background Cancer of unknown primary site (CUP is considered an aggressive metastatic disease but whether the prognosis differs from metastatic cancers of known primary site is not known. Such data may give insight into the biology of CUP and the metastatic process in general. Methods 6,745 cancer patients, with primary metastatic cancer at diagnosis, were identified from the Swedish Cancer Registry, and were compared with 2,881 patients with CUP. Patients were diagnosed and died between 2002 and 2008. The influence of the primary site, known or unknown, on survival in patients with metastases at specific locations was investigated. Hazard ratios (HRs of death were estimated for several sites of metastasis, where patients with known primary sites were compared with CUP patients. Results Overall, patients with metastatic cancers with known primary sites had decreased hazards of death compared to CUP patients (HR = 0.69 [95% CI = 0.66–0.72]. The exceptions were cancer of the pancreas (1.71 [1.54–1.90], liver (1.58 [1.36–1.85], and stomach (1.16 [1.02–1.31]. For individual metastatic sites, patients with liver or bone metastases of known origin had better survival than those with CUP of the liver and bone. Patients with liver metastases of pancreatic origin had an increased risk of death compared with patients with CUP of the liver (1.25 [1.06–1.46]. The median survival time of CUP patients was three months. Conclusions Patients with CUP have poorer survival than patients with known primaries, except those with brain and respiratory system metastases. Of CUP sites, liver metastases had the worst prognosis. Survival in CUP was comparable to that in metastatic lung cancer. The aggressive behavior of CUP may be due to initial immunosuppression and immunoediting which may allow accumulation of mutations. Upon escape from the suppressed state an unstoppable tumor spread ensues. These novel data on the epidemiology of the

    AIM: To explore the oncological outcomes of unresectable lung metastases without extrapulmonary metastases in colorectal cancer. METHODS: Patients with unresectable isolated lung metastases from colorectal cancer were prospectively collected in a single institution during a 5-year period. All patients received either the fluorouracil/leucovorin plus oxaliplatin, fluorouracil/leucovorin plus irinotecan or capecitabine plus oxaliplatin regimen as first-line treatment. The resectability after preoperative chemotherapy was evaluated. Patients’ outcome and predictive factors for overall survival were also investigated by univariate and multivariate analysis. RESULTS: A total of 70 patients were included in the study. After standardized first-line chemotherapy, only 4 patients (5.7%) were converted to resectable disease. The median overall survival time in all patients was 19 mo (95% CI: 12.6-25.4), with a 2-year overall survival rate of 38.8%. No survival difference was found among different first-line chemotherapeutic regimens. Prognostic analysis demonstrated that only the first response assessment for first-line treatment was the independent factor for predicting overall survival. The median survival time in partial response, stable disease and progressive disease patients were 27 mo, 16 mo and 8 mo (P = 0.00001). CONCLUSION: Pulmonary metastasectomy can only be performed in a small part of unresectable lung metastases patients after chemotherapy. Patients’ first response assessment is an important prognostic factor. PMID:20614489

    Urologists have two scenarios where they have to address bone loss or increased risk of fractures in men with prostate cancer. In the first setting, a patient who has been started on androgen deprivation therapy may develop cancer-treatment-induced bone loss. In the second setting, a patient's prostate cancer may have metastasized to the bone. This article describes six steps to manage bone health in patients diagnosed with prostate cancer in a community practice.

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

    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.

    Full Text Available Bone scintigraphy has been widely used to assess skeletal metastasis in patients with breast cancer. 18F-FDGPET/CT is another imaging modality that has gained previously wide use to determine metastasis based on increased glucose metabolism in malignant cells. Generally, these two modalities give similar results in evaluation of bone metastasis of breast cancer. In this breast cancer case, 99mTc-MDP bone scintigraphy showed normal findings in regards to skeletal metastasis while 18FFDG-PET/CT, contrast-enhanced CT and MRI revealed multiple metastatic focuses.

    Unusual sites of metastases are recognized in patients with renai cell carcinoma (RCC). However, the prognostic implications of these sites are not well understood. We used the Memorial Sloan-Kettering Cancer Center (MSKCC) risk classification for metastatic RCC to evaluate 912 consecutive patients with RCC managed at the Singapore General Hospital between 1990 and 2009. Among these patients, 301 had metastases either at diagnosis or during the course of illness. Nasal metastases, all arising from clear cell RCC, were identified histologically in 4 patients (1.3% of those with metastasis). All 4 patients were classified as MSKCC poor prognosis by current risk criteria. Nasal metastases were significantly associated with lung and bone metastases. The frequency of nasal metastases in patients with metastatic RCC is about 1%, occurring predominantly in patients with clear cell RCC. Nasal metastases are associated with poor prognosis as estimated by the MSKCC risk classification, with attendant implications for selection of targeted therapy, and are usually associated with multi-organ dissemination, including concurrent lung and bone involvement.

    To assess the hypothesis that the dynamics of plasma angiogenic and inflammatory cytokines after docetaxel chemotherapy with or without the c-kit/abl/platelet-derived growth factor receptor (PDGFR) inhibitor imatinib mesylate for prostate cancer are associated with outcome, the kinetics of 17 plasma cytokines before versus after chemotherapy were assessed and associations with progression-free survival (PFS) examined. After adjusting for multiple tests, significantly different declines in placental growth factor (PIGF), soluble vascular endothelial growth factor receptor-1 (VEGFR1), VEGF, and soluble c-kit were observed with docetaxel plus imatinib (n=41) compared to docetaxel alone (n=47). Based on a piecewise linear regression model for change in concentration of each cytokine as a function of the probability of change in p-PDGFR in vivo, only the dynamics of PIGF (Pmodel for PFS, a rise in human matrix metalloproteinase 9 after docetaxel alone associated with a longer PFS. Distinct plasma angiogenic cytokines are modified by imatinib and partitioned by in vivo p-PDGFR dynamics after docetaxel chemotherapy for metastatic prostate cancer. Plasma PIGF and soluble c-kit kinetics are candidate biomarkers of imatinib effect. The predictive value of human matrix metalloproteinase 9 kinetics for docetaxel efficacy requires prospective validation.

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

    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 after treatment. Results. Relief of pain was observed in 76% of the patients receiving HBI with 8.8% of the patients experiencing complete pain relief with no residual pain in the treated field. For most patients, the pain relief was lasting throughout the follow-up period. About one third of the patients were able to reduce their intake of analgesics. Grade 1-2 diarrhoea was the most common side effect observed in 49% of the patients two weeks after treatment. Mild pulmonary symptoms (grade 1-2) were observed in four of seven patients receiving upper HBI. No clear effect was observed on the patients' global quality of life.Conclusion. Single fraction HBI is safe and effective providing long lasting pain reduction in 76% of patients with multiple bone metastases.

    Skeletal tumour burden is a biomarker of prognosis and survival in cancer patients. This study proposes a novel method based on the linear quadratic model to predict the reduction in metastatic tumour burden as a function of the absorbed doses delivered from molecular radiotherapy treatments. The range of absorbed doses necessary to eradicate all the bone lesions and to reduce the metastatic burden was investigated in a cohort of 22 patients with bone metastases from castration-resistant prostate cancer. A metastatic burden reduction curve was generated for each patient, which predicts the reduction in metastatic burden as a function of the patient mean absorbed dose, defined as the mean of all the lesion absorbed doses in any given patient. In the patient cohort studied, the median of the patient mean absorbed dose predicted to reduce the metastatic burden by 50% was 89 Gy (interquartile range: 83–105 Gy), whilst a median of 183 Gy (interquartile range: 107–247 Gy) was found necessary to eradicate all metastases in a given patient. The absorbed dose required to eradicate all the lesions was strongly correlated with the variability of the absorbed doses delivered to multiple lesions in a given patient (r  =  0.98, P  <  0.0001). The metastatic burden reduction curves showed a potential large reduction in metastatic burden for a small increase in absorbed dose in 91% of patients. The results indicate the range of absorbed doses required to potentially obtain a significant survival benefit. The metastatic burden reduction method provides a simple tool that could be used in routine clinical practice for patient selection and to indicate the required administered activity to achieve a predicted patient mean absorbed dose and reduction in metastatic tumour burden.

    Full Text Available Aim.The purpose of this study was to examine the outcome of patients with skeletal metastases from well-differentiated thyroid carcinoma and analyse the effect of variables that influence the prognosis of this disease. Method. We retrospectively reviewed 352 patients treated and followed-up at the Charlotte Maxeke Johannesburg Academic Hospital’s thyroid cancer clinic from 1982 - 1999. Findings. Skeletal metastases were diagnosed in 24 (6.8%, 17 at presentation to the thyroid clinic, and 7 at follow-up. Patients’ ages ranged from 30 - 77 years (mean 53.9 years and the female:male ratio was 3.8:1. Based on the original pathology reports from resected tumours, 9 were papillary and 15 were follicular cancers. Twenty-three of the 24 patients underwent thyroid surgery as the initial management – total thyroidectomy in 18, subtotal thyroidectomy in 3, and lobectomy plus neck dissection in one. The diagnosis of thyroid cancer was based on lobectomy in a single subject. Radioactive iodine (RAI was used as part of the original treatment; external radiation therapy (XRT was mainly used to alleviate severe symptoms. Twenty-one patients (87.5% were treated with RAI; 11 (45.8% received radiotherapy. Seven patients died – 4 from neurological disease directly associated with bone metastases. Of the 17 surviving patients, 2 appeared to be disease-free, 8 were asymptomatic despite overt bony disease, and 7 had persistent symptoms which much improved in 5. Bone metastases were uncommon, and follicular cancer predominated in this survey. Conclusion. RAI therapy improves quality of life in most patients. There is a place for XRT.

    Median survival from liver metastases secondary to breast cancer is only a few months, with very rare 5-year survival. This study reviewed 145 patients with liver metastases from breast cancer to determine factors that may influence survival. Data were analysed using Kaplan-Meier survival curves, univariate and multivariate analysis. Median survival was 4.23 months (range 0.16-51), with a 27.6% 1-year survival. Factors that significantly predicted a poor prognosis on univariate analysis included symptomatic liver disease, deranged liver function tests, the presence of ascites, histological grade 3 disease at primary presentation, advanced age, oestrogen receptor (ER) negative tumours, carcinoembryonic antigen of over 1000 ng ml(-1) and multiple vs single liver metastases. Response to treatment was also a significant predictor of survival with patients responding to chemo- or endocrine therapy surviving for a median of 13 and 13.9 months, respectively. Multivariate analysis of pretreatment variables identified a low albumin, advanced age and ER negativity as independent predictors of poor survival. The time interval between primary and metastatic disease, metastases at extrahepatic sites, histological subtype and nodal stage at primary presentation did not predict prognosis. Awareness of the prognostic implications of the above factors may assist in selecting the most appropriate treatment for these patients.British Journal of Cancer (2003) 89, 284-290. doi:10.1038/sj.bjc.6601038 www.bjcancer.com

    The purpose was to evaluate the clinical results of stereotactic radiotherapy in primary liver tumors and hepatic metastases. Five patients with primary liver cancer and 39 patients with 51 hepatic metastases were treated by stereotactic radiotherapy since 1997. Twenty-eight targets were treated in a 'low-dose'-group with 3x10 Gy (n=27) or 4x7 Gy (n=1) prescribed to the PTV-encl. 65%-isodose. In a 'high-dose'-group patients were treated with 3x12 - 12.5 Gy (n=19; same dose prescription) or 1x26 Gy/PTV-enclosing 80%-isodose (n=9). Median follow-up was 15 months (2-48 months) for primary liver cancer and 15 months (2-85 months) for hepatic metastases. While all primary liver cancers were controlled, nine local failures (3-19 months) of 51 metastases were observed resulting in an actuarial local control rate of 92% after 12 months and 66% after 24 months and later. A borderline significant correlation between dose and local control was observed (p=0.077): the actuarial local control rate after 12 and 24?months was 86% and 58% in the low-dose-group versus 100% and 82% in the high-dose-group. In multivariate analysis high versus low-dose was the only significant factor predicting local control (p=0.0089). Overall survival after 1 and 2 years was 72% and 32% for all patients and was impaired due to systemic progression of disease. No severe acute or late toxicity exceeding RTOG/EORTC-score 2 were observed. Stereotactic irradiation of primary liver cancer and hepatic metastases offers a locally effective treatment without significant complications in patients, who are not amenable for surgery. Patient selection is important, because those with low risk for systemic progression are more likely to benefit from this approach.

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

    Full Text Available The discovery of various driver pathways and targeted small molecule agents/antibodies have revolutionized the management of metastatic breast cancer. Currently, the major targets of clinical utility in breast cancer include the human epidermal growth factor receptor 2 (HER2 and epidermal growth factor receptor (EGFR, vascular endothelial growth factor (VEGF receptor, mechanistic target of rapamycin (mTOR pathway, and the cyclin-dependent kinase 4/6 (CDK-4/6 pathway. Brain metastasis, however, remains a thorn in the flesh, leading to morbidity, neuro-cognitive decline, and interruptions in the management of systemic disease. Approximately 20%–30% of patients with metastatic breast cancer develop brain metastases. Surgery, whole brain radiation therapy, and stereotactic radiosurgery are the traditional treatment options for patients with brain metastases. The therapeutic paradigm is changing due to better understanding of the blood brain barrier and the advent of tyrosine kinase inhibitors and monoclonal antibodies. Several of these agents are in clinical practice and several others are in early stage clinical trials. In this article, we will review the common targetable pathways in the management of breast cancer patients with brain metastases, and the current state of the clinical development of drugs against these pathways.

    2009-12-01

    Full Text Available Abstract Background Microarray technology has allowed to molecularly characterize many different cancer sites. This technology has the potential to individualize therapy and to discover new drug targets. However, due to technological differences and issues in standardized sample collection no study has evaluated the molecular profile of epithelial human cancer in a large number of samples and tissues. Additionally, it has not yet been extensively investigated whether metastases resemble their tissue of origin or tissue of destination. Methods We studied the expression profiles of a series of 1566 primary and 178 metastases by unsupervised hierarchical clustering. The clustering profile was subsequently investigated and correlated with clinico-pathological data. Statistical enrichment of clinico-pathological annotations of groups of samples was investigated using Fisher exact test. Gene set enrichment analysis (GSEA and DAVID functional enrichment analysis were used to investigate the molecular pathways. Kaplan-Meier survival analysis and log-rank tests were used to investigate prognostic significance of gene signatures. Results Large clusters corresponding to breast, gastrointestinal, ovarian and kidney primary tissues emerged from the data. Chromophobe renal cell carcinoma clustered together with follicular differentiated thyroid carcinoma, which supports recent morphological descriptions of thyroid follicular carcinoma-like tumors in the kidney and suggests that they represent a subtype of chromophobe carcinoma. We also found an expression signature identifying primary tumors of squamous cell histology in multiple tissues. Next, a subset of ovarian tumors enriched with endometrioid histology clustered together with endometrium tumors, confirming that they share their etiopathogenesis, which strongly differs from serous ovarian tumors. In addition, the clustering of colon and breast tumors correlated with clinico-pathological characteristics

    Background and Aim A close relationship between phosphoglycerate kinase 1 (PGK1) and the CXCR4/SDF1 axis (chemokine receptor 4/stromal cell derived factor 1) has been shown for several cancers. However, the role of PGK1 has not been investigated for neuroblastoma, and PGK1 might be a therapeutic target for this tumor entity. The aim of the current study was to evaluate the role of PGK1 expression in neuroblastoma patients, to determine the impact of PGK1 expression levels on survival, and to correlate PGK1 expression with CXCR4 expression and bone marrow dissemination. Materials and Methods Samples from 22 patients with neuroblastoma that were surgically treated at the University Medical Center Hamburg-Eppendorf were evaluated for expression of PGK1 and CXCR4 using immunohistochemistry. Results were correlated with clinical parameters, metastases and outcome of patients. Immunocytochemistry, proliferation and expression analysis of CXCR4 and PGK1 were performed in neuroblastoma cell lines. Results PGK1 is expressed in neuroblastoma cells. PGK1 expression is significantly positively correlated with CXCR4 expression and tumor dissemination to the bone marrow. Moreover the expression of PGK1 is significantly associated with a negative impact on survival in patients with neuroblastoma. PGK1 is downregulated by inhibition of CXCR4 in neuroblastoma cells. Conclusion PGK1 appears to play an important role for neuroblastoma, predicting survival and tumor dissemination. Further in vivo studies outstanding, it is a candidate target for novel therapeutic strategies. PMID:24376734

    Full Text Available Background. The worldwide increasing incidence of thyroid cancer (TC is mainly due to a rise in its major form of differentiated TC (DTC: papillary. Most patients with DTC have a good prognosis; 10-year survival overall rates are as high as 85 %, but not greater than 40 % in a group of patients with distant metastases. At the same time, the lung is the most frequent target for distant metastases, accounting for 70 % of all sites.Objective: to estimate and compare the capabilities of different diagnostic techniques to detect lung metastases of DTC. Materials and methods. The results of diagnosing lung metastases were retrospectively analyzed in 36 patients (33 women and 3 men; mean age 53 years with DTC (29 patients with papillary TC and 7 with follicular TC treated at the department of radiotherapy with systemic therapy, Chelyabinsk Regional Clinical Oncology Center from 2011 to 2014.Results. Chest X-ray could reveal pulmonary metastases in 13 (36 % patients; lung pathology foci were absent in 23 (64 % patients. 131I whole-body scintigraphy (WBS proved to be of informative value in 24 (66.7 % patients, it displayed no increased accumulation of the radiopharmaceutical in the lung of 12 (33.3 % cases. Multislice spiral computed tomography (MSCT of the chest was carried out in 22 (61 % patients; out of them 21 (95.5 % were found to have 1.4-to-20-mm lung cancer foci. 18Fluorodeoxyglucose (18FDG positron emission tomography / computed tomography (PET / CT was performed in 18 (50 % patients, which showed 3–26-mm lung pathology foci in all the patents; out of them 16 (88.9 % were detected to have metastases owing to the CT component of this method. Thus, the highest sensitivity was exhibited by MSCT (95.5 %, 18FDG PET / CT (100 % due to its CT component, and 131I WBS (66.7 %.Conclusion. When lung metastases of DTC are suspected, 1 chest X-ray should be used as a screening test; 2 131I WBS should be performed in all patients; 3 MSCT of the chest is

  8. Esophageal Cancer with Bone Marrow Hyperplasia Mimicking Bone Metastasis: Report of a Case

    Hiromi Yasuda

    2016-11-01

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

    2017-03-01

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

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

    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.

    Dima Y. Jadaan

    2015-01-01

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

    Detection and segmentation of ovarian cancer metastases have great clinical impacts on women’s health. However, the random distribution and weak boundaries of metastases significantly complicate this task. This paper presents a variational framework that combines region competition based level set propagation and image matching flow computation to jointly detect and segment metastases. Image matching flow not only detects metastases, but also creates shape priors to reduce over-segmentation. ...

  5. Acupuncture for Cancer-Induced Bone Pain?

    Directory of Open Access Journals (Sweden)

    Carole A. Paley

    2011-01-01

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

    growth factor receptor 2 subtypes had similar median survival duration and mortality risk. Patients with triple-negative breast cancer had a median survival duration of only 9.9 months. CONCLUSION: Patients with spinal metastases with ER/HR (-) status and triple-negative breast cancer could be downgraded...... from score "5" to "3" in Tokuhashi scoring system and from "slow growth" to "moderate growth" in Tomita scoring system. Spine surgeons should be critical before performing high-risk extensive surgery in patients with ER/HR (-) status, and especially, in those with triple-negative status. LEVEL...... hazards regression model unadjusted and adjusted by age were used. RESULTS: Patients with ER-negative (-) breast cancer had 11 months shorter median survival duration (10.6 vs. 21.5 mo) and 48% higher mortality risk (P=0.03) than those with ER-positive (+) breast cancer. Patients with PgR (-) status had...

    Full Text Available Purpose. To check whether primary involvement of brain/spinal cord by bone/soft tissue sarcomas’ metastases in children is as rare as described and to present various morphological forms of bone/soft tissue sarcomas’ CNS metastases. Methods. Patients with first diagnosis in 1999–2014 treated at single center were included with whole course of disease evaluation. Brain/spinal canal magnetic resonance imaging (MRI/computed tomography were performed in cases suspicious for CNS metastases. Extension from skull/vertebral column metastases was excluded. Results. 550 patients were included. MRI revealed CNS metastases in 19 patients (incidence 3.45%, 14 boys, aged 5–22 years. There were 12/250 osteosarcoma cases, 2/200 Ewing’s sarcoma, 1/50 chondrosarcoma, 3/49 rhabdomyosarcoma (RMS, and 1/1 malignant mesenchymoma. There were 10 single metastases and 7 cases of multiple ones; in 2 RMS cases only leptomeningeal spread in brain and spinal cord was found. Calcified metastases were found in 3 patients and hemorrhagic in 4. In one RMS patient there were numerous solid, cystic, hemorrhagic lesions and leptomeningeal spread. Conclusions. CNS metastases are rare and late in children with bone/soft tissue sarcomas, although in our material more frequent (3.45% than in other reports (0.7%. Hematogenous spread to brain and hemorrhagic and calcified lesions dominated in osteosarcoma. Ewing sarcoma tended to metastasize to skull bones. Soft tissue sarcomas presented various morphological forms.

    Myxoid liposarcomas (MLS) have a tendency to metastasize to unusual sites. We report an unusual case of bone metastases not detected by bone scan and neither by fluorodeoxyglucose positron emission tomography (PET-FDG) and successfully identified with magnetic resonance imaging (MRI) in a patient with metachronic MLS. Histopathological examination of the primary tumor evidenced a tumor with unfavorable prognostic markers, and the biopsy of an iliac bone lesion confirmed the diagnosis of metastatic disease. On histological grounds, the tumor showed features of a more differentiated neoplasm without foci of round cells or necrosis in the latter. MRI allowed the identification of disseminated disease compared to computed tomography (CT) and PET scans. Thus, because of the heterogeneous histological features of MLS and the biological behavior of the disease, a combined approach of FDGPET-CT and MRI, may allow a more accurate staging of soft tissue sarcomas.

    2014-02-01

    Metastatic disease to bone is commonly seen in the advanced stages of many cancers. The cardinal symptom, pain, is often the cause of significant morbidity and reduced quality of life. Treatment of bone pain includes nonsteroidal analgesics and opiates; however, long-term use of these drugs is commonly associated with significant side effects, and tolerance is common. External-beam radiation therapy is effective mainly in localized disease sites. Bone-targeting radiopharmaceuticals are beneficial in the management of patients with multiple metastatic lesions. This article focuses on the 3 most commonly used agents: the Food and Drug Administration-approved (89)Sr-chloride, (153)Sm-ethylenediaminetetramethylene phosphonic acid (EDTMP), and (223)Ra-dichloride. We will discuss the physical characteristics, clinical data, dosage, and administration of these agents, including optimal patient selection and toxicity associated with their use. These radioactive agents have proven efficacy in the treatment of painful osseous metastases from prostate cancer and breast cancer. Significant recent advances include use of these agents in combination with chemotherapy and the use of the α emitter (223)Ra-dichloride in prostate cancer, primarily to improve survival and skeletal related events. The review is presented in 2 parts. The first will discuss the characteristics and clinical use of (223)Ra-dichloride, and the second will discuss the β emitters (89)Sr and (153)Sm-EDTMP.

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

    Full Text Available Patients with triple receptor-negative breast cancer often develop aggressive metastatic disease, which also might involve the brain. In many cases, systemic and local treatment is needed. It is important to consider the toxicity of chemo- and radiotherapy, especially when newly approved drugs become available. Randomised studies leading to drug approval often exclude patients with newly diagnosed brain metastases. Here we report our initial experience with eribulin mesylate and whole-brain radiotherapy (WBRT in a heavily pretreated patient with multiple brain, lung, and bone metastases from triple receptor-negative breast cancer. Eribulin mesylate was given after 4 previous lines for metastatic disease. Two weeks after the initial dose, that is, during the first cycle, the patient was diagnosed with 5 brain metastases with a maximum size of approximately 4.5 cm. She continued chemotherapy and received concomitant WBRT with 10 fractions of 3 Gy. After 3 cycles of eribulin mesylate, treatment was discontinued because of newly diagnosed liver metastases and progression in the lungs. No unexpected acute toxicity was observed. The only relevant adverse reactions were haematological events after the third cycle (haemoglobin 9.5 g/dL, leukocytes 3.1×109/L. The patient died from respiratory failure 18.5 months from diagnosis of metastatic disease, and 2.7 months from diagnosis of brain metastases. To the best of our knowledge, this is the first report on combined WBRT and eribulin mesylate.

    2014-01-01

    Full Text Available This study examined the usefulness of diffusion-weighted (DW Magnetic Resonance Imaging (MRI in monitoring bone metastases response to radiation therapy in 15 oligometastatic patients. For each metastasis, both mean apparent diffusion coefficient (ADC changes and high b-value DW metastasis/muscle signal intensity ratio (SIR variations were evaluated at 30 ± 5 days and 60 ± 7 days after the end of treatment. On baseline DW-MRI, all bone metastases were hyperintense and had signal intensities higher than normal bone marrow on calculated ADC maps. At follow-up evaluations, 4 patterns of response were identified: (I decreased high b-value DW SIR associated with increased mean ADC (83.3% of cases; (II increased mean ADC with no change of high b-value DW SIR (10% of cases; (III decreased both high b-value DW SIR and mean ADC (3.3% of cases; (IV a reduction in mean ADC associated with an increase in high b-value DW SIR compared to pretreatment values (3.3% of cases. Patterns (I and (II suggested a good response to therapy; pattern (III was classified as indeterminate, while pattern (IV was suggestive of disease progression. This pattern approach may represent a useful tool in the differentiation between treatment-induced necrosis and highly cellular residual tumor.

    The aim of this study was to observe effects of ascorbic acid application on pain, performance status, and survival time in cancer patients. A retrospective cohort of 39 patients with bone metastases treated with radiotherapy was identified. All patients were radiotherapy-resistant. Fifteen patients who received chemotherapy, and 15 patients who received an infusion of 2.5 g ascorbic acid were included in the study. Nine control patients were treated with neither chemotherapy nor vitamin C. Eastern Cooperative Oncology Group Performance Status Scale and Visual Analog Scale were used to determine performance status and pain assessments. Survival time and rate in patients were defined. Statistical analyses were performed to compare the results of groups. Performance status was increased in 4 patients of vitamin C group and 1 patient of chemotherapy group, whereas performance status in control group was decreased. A median reduction of 50% in pain was observed among the patients in the vitamin C group. Median survival time was 10 mo in patients receiving ascorbic acid, whereas the chemotherapy and control groups had a median survival of 2 mo. Intravenous vitamin C application seems to reduce pain in patients in comparison to other patients who did not receive it. Patient performance status and survival rate were increased using vitamin C.

    The liver is the commonest site of distant metastasis ofcolorectal cancer and nearly half of the patients withcolorectal cancer ultimately develop liver involved duringthe course of their diseases. Surgery is the only therapythat offers the possibility of cure for patients with hepaticmetastatic diseases. Five-year survival rates after resectionof all detectable liver metastases can be up to 40 %.Unfortunately, only 25 % of patients with colorectal livermetastases are candidates for liver resection, while the othersare not amenable to surgical resection. Regional therapiessuch as radiofrequency ablation and cryotherapy may beoffered to patients with isolated unresectable metastasesbut no extrahepatic diseases. Hepatic artery catheterchemotherapy and chemoembolization and portal veinembolization are often used for the patients with extensiveliver metastases but without extrahepatic diseases, whichare not suitable for regional ablation. For the patients withmetastatic colorectal cancer beyond the liver, systemicchemotherapy is a more appropriate choice. Immunotherapyis also a good option when other therapies are used incombination to enhance the efficacy. Selective internalradiation therapy is a new radiation method which can beused in patients given other routine therapies Without effects.

    Objective: To calculate the focus absorption dose of 153Sm-EDTMP with the Monte Carlo (MC) EGS4 method for treatment of bone metastases from nasopharyngeal carcinoma or breast cancer, and investigate the relationship between the focus absorption dose and painkilling effect of 153Sm-EDTMP. Methods: Four patients with multiple bone metastases from nasopharyngeal or breast carcinoma and suffered from grade Ⅳ bone pain were treated with radionuclide internal irradiation of 153Sm-EDTMP. The absorption dose and dose distribution of bone metastases and other targeted organs were calculated with MC EGS4 program based on the time-order SPECT/CT scanning and the measurement of the radioactivity in the urine accumulation. The release of bone pain and the improvement of life quality were observed. Results: Bone pain of the patients was significantly alleviated to grade Ⅱ for 3-4 weeks after internal 153Sm-EDTMP irradiation. The 3-dimensional absorption dose distribution image of bone metastases and targeted organs showed that the dose distribution in bone metastases was not asymmetrical. After injection of 0.65 × 37 MBq/kg 153Sm-EDTMP, the highest absorption dose in bone lesions was about 4.9-5.9 Gy, and the dose in the lesion margin was about 2.0 Gy. Using the highest dose as reference dose point, the relative absorption dose values of bone marrow, vertebra and sex organ near lesions were 0.48-1.1 Gy, 0.51-0.85 Gy, and 0.01-0.14 Gy, respectively. Conclusion: The absorption dose of bone metastases is significantly lower than treatment dose of 30 Gy after single irradiation of 153Sm-EDTMP. The painkilling effect is limited and in accordance with clinical observation.

  2. Downregulation of CXCR4 in Metastasized Breast Cancer Cells and Implication in Their Dormancy.

    Directory of Open Access Journals (Sweden)

    Kentaro Nobutani

    Full Text Available Our understanding of the mechanism of cancer dormancy is emerging, but the underlying mechanisms are not fully understood. Here we analyzed mouse xenograft tumors derived from human breast cancer tissue and the human breast cancer cell line MDA-MB-231 to identify the molecules associated with cancer dormancy. In immunohistological examination using the proliferation marker Ki-67, the tumors included both proliferating and dormant cancer cells, but the number of dormant cells was remarkably increased when they metastasized to the lung. In the gene expression analysis of the orthotopic cancer cells by a single-cell multiplex real-time quantitative reverse transcription PCR followed by flow cytometric analysis, restrained cellular proliferation was associated with downregulation of the chemokine receptor CXCR4. In the immunohistological and flow cytometric analyses, the expression level of CXCR4 in the metastasized cancer cells was decreased compared with that in the cancer cells in orthotopic tumors, although the expression level of the CXCR4 ligand CXCL12 was not reduced in the lung. In addition, the proliferation of the metastasized cancer cells was further decreased by the CXCR4 antagonist administration. In the ex vivo culture of the metastasized cancer cells, the expression level of CXCR4 was increased, and in the xenotransplantation of ex vivo cultured cancer cells, the expression level of CXCR4 was again decreased in the metastasized cancer cells in the lung. These findings indicate that CXCR4 is downregulated in metastasized breast cancer cells and implicated in their dormancy.

    Full Text Available Maintaining bone health remains a clinical challenge in patients with prostate cancer (PC who are at risk of developing metastatic bone disease and increased bone loss due to hormone ablation therapy. In patients with cancer-treatment induced bone loss (CTIBL, antiresorptive agents have been shown to improve bone mineral density (BMD and to reduce the risk of fractures. For patients with bone metastases, both zoledronic acid and denosumab delay skeletal related events (SREs in the castration resistant stage of disease. Novel agents targeting the Wnt inhibitors dickkopf-1 and sclerostin are currently under investigation for the treatment of osteoporosis and malignant bone disease. New antineoplastic drugs such as abiraterone, enzalutamide, and Radium-223 are capable of further delaying SREs in patients with advanced PC. The benefit of antiresorptive treatment for patients with castration sensitive PC appears to be limited. Recent trials on the use of zoledronic acid for the prevention of bone metastases failed to be successful, whereas denosumab delayed the occurrence of bone metastases by a median of 4.1 months. Currently, the use of antiresorptive drugs to prevent bone metastases still remains a field of controversies and further trials are needed to identify patient subgroups that may profit from early therapy.

  4. Pheochromocytoma presenting as musculoskeletal pain from bone metastases

    1987-10-01

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

    Full Text Available Evidence about distribution patterns of brain metastases with regard to breast cancer subtypes and its influence on the prognosis of patients is insufficient. Clinical data, cranial computed tomography (CT and magnetic resonance imaging (MRI scans of 300 breast cancer patients with brain metastases (BMs were collected retrospectively in four centers participating in the Brain Metastases in Breast Cancer Registry (BMBC in Germany. Patients with positive estrogen (ER, progesterone (PR, or human epidermal growth factor receptor 2 (HER2 statuses, had a significantly lower number of BMs at diagnosis. Concerning the treatment mode, HER2-positive patients treated with trastuzumab before the diagnosis of BMs showed a lower number of intracranial metastases (p < 0.001. Patients with a HER2-positive tumor-subtype developed cerebellar metastases more often compared with HER2-negative patients (59.8% vs. 44.5%, p = 0.021, whereas patients with triple-negative primary tumors had leptomeningeal disease more often (31.4% vs. 18.3%, p = 0.038. The localization of Brain metastases (BMs was associated with prognosis: patients with leptomeningeal disease had shorter survival compared with patients without signs of leptomeningeal disease (median survival 3 vs. 5 months, p = 0.025. A shorter survival could also be observed in the patients with metastases in the occipital lobe (median survival 3 vs. 5 months, p = 0.012. Our findings suggest a different tumor cell homing to different brain regions depending on subtype and treatment.

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

    Background APOBEC3B was recently identified as a gain-of-function enzymatic source of mutagenesis, which may offer novel therapeutic options with molecules that specifically target this enzyme. In primary breast cancer, APOBEC3B mRNA is deregulated in a substantial proportion of cases and its expression is associated with poor prognosis. However, its expression in breast cancer metastases, which are the main causes of breast cancer-related death, remained to be elucidated. Patients and methods RNA was isolated from 55 primary breast cancers and paired metastases, including regional lymph node (N = 20) and distant metastases (N = 35). APOBEC3B mRNA levels were measured by RT-qPCR. Expression levels of the primary tumors and corresponding metastases were compared, including subgroup analysis by estrogen receptor (ER/ESR1) status. Results Overall, APOBEC3B mRNA levels of distant metastases were significantly higher as compared to the corresponding primary breast tumor (P = 0.0015), an effect that was not seen for loco-regional lymph node metastases (P = 0.23). Subgroup analysis by ER-status showed that increased APOBEC3B levels in distant metastases were restricted to metastases arising from ER-positive primary breast cancers (P = 0.002). However, regarding ER-negative primary tumors, only loco-regional lymph node metastases showed increased APOBEC3B expression when compared to the corresponding primary tumor (P = 0.028). Conclusion APOBEC3B mRNA levels are significantly higher in breast cancer metastases as compared to the corresponding ER-positive primary tumors. This suggests a potential role for APOBEC3B in luminal breast cancer progression, and consequently, a promising role for anti-APOBEC3B therapies in advanced stages of this frequent form of breast cancer.

    Full Text Available Abstract Giant cell tumor (GCT of bone is a locally destructive tumor that occurs predominantly in long bones of post-pubertal adolescents and young adults, where it occurs in the epiphysis. The majority are treated by aggressive curettage or resection. Vascular invasion outside the boundary of the tumor can be seen. Metastasis, with identical morphology to the primary tumor, occurs in a few percent of cases, usually to the lung. On occasion GCTs of bone undergo frank malignant transformation to undifferentiated sarcomas. Here we report a case of GCT of bone that at the time of recurrence was found to have undergone malignant transformation. Concurrent metastases were found in the lung, but these were non-transformed GCT.

    Background The incidence of brain metastases in patients with breast cancer is approximately 10%-16%,and survival after diagnosis of brain metastases is usually short.This study was designed to evaluate the risk factors associated with brain metastases in advanced breast cancer patients,with a view to help predict patient groups with high risk of brain metastases.Methods In total,295 patients with advanced breast cancer were evaluated.All patients were pathologically confirmed and metastatic lesions were confirmed pathologically or by imaging.All patients were examined at least once every 6 months with head CT or MRI.Patients showing symptoms underwent immediate inspection,and brain metastatic lesions were confirmed by head CT and/or MRI.Results At a median follow-up of 12 months from the occurrence of metastases,brain metastases had occurred in 49 patients (16.6%).In our univariate analysis,variables significantly related to increased risk of brain metastases were hormone receptor-negative tumors,epidermal growth factor receptor 2 (HER2)-positive tumors,and multiple distant metastases.Patients with dominant tumor sites in soft tissue,or defined as Luminal A subtype,tended to have a lower risk of brain metastases than patients with visceral metastases,Luminal B subtype,triple-negative subtype or HER2-enriched subtype tumors.Conclusions Our results strongly suggest that factors such as Luminal B,triple-negative,and HER2-enriched subtypes are high risk factors for brain metastases.These data,therefore,provide pivotal clinical evidence towards a comprehensive understanding of the risk factors of brain metastases in advanced breast cancer patients.

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

    The exact tumor stage needs to be determined with the help of the TNM classification before the optimal therapeutic procedure for the patient is proposed. If M-staging is under question bone metastases must be excluded or be proven. Bone scintigraphy plays a major role for bone metastases screening of patients with lung cancer, prostate and breast cancer in whom osseous disease is often present. The result of bone scintigraphy has a significant impact on further therapy e.g. whether curative treatment is possible, whether operative resection or chemotherapy must be performed. PET and PET/CT with {sup 18}F sodium fluoride are new imaging modalities for the detection of bone metastases. PET with {sup 18}F fluoride allows for cross sectional imaging with high resolution in a way that is not achievable by conventional bone scintigraphy. Pharmacokinetic properties of {sup 18}F fluoride are advantageous and lead to high tracer uptake and quick renal clearance. This allows the acquisition of high quality images as early as one hour after the injection. Compared with planar whole body scintigraphy, {sup 18}F fluoride is able to detect significantly more bone metastases (especially in the vertebral column). In comparison to bone SPECT, less additional metastatic lesions are detected by bone PET. This could be demonstrated in detail for lung and prostate cancers. In a small group of patients, {sup 18}F fluoride will diagnose osseous metastatic disease in spite of a negative planar whole body scintigraphy and a negative bone SPECT. However, specificity of bone SPECT is not markedly improved by {sup 18}F fluoride PET. It seems that new camera systems like PET/CT and SPECT/CT can enhance specificity impressively by adding the CT component to exactly localize a tracer accumulation. (orig.)

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; α-fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was revaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

    Renal cell cancer rarely metastasizes to the thyroid gland, and it has been reported to present as a solitary mass. We present a case of diffuse thyroid cancer metastases from renal cell cancer. Bilateral internal jugular vein tumor thrombi were also present. To the best of our knowledge, this is the first description of diffuse thyroid metastases from renal cell cancer in the English literature. Renal cell cancer metastases should be considered in the differential of thyroid imaging abnormalities arising in the setting of known renal cell carcinoma, particularly late in the course of disease. This is frequently associated with internal jugular vein thrombi, which should be evaluated with an abnormal thyroid. Thyroglobulin levels are usually normal in such patients.

    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.

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

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

    AIM: Liver metastases from breast cancer (BCLM) are associated with poor prognosis. Cytotoxic chemotherapy can result in regression of tumor lesions and a decrease in symptoms. Available data, in the literature, also suggest a subgroup of patients rraay berefit from surgery, but few talked about transcatheter arterial chemoembolization (TACE).We report the results of TACE and systemic chemotherapy for patients with liver metastases from breast cancer and evaluate the prognostic factors. METHODS: Forty-eight patients with liver metastases, from proved breast primary cancer were treated with TACEor systemic chemotherapy between January 1995 and December 2000. Treatment results were assessed according to WHO criteria, along with analysis of prognostic factors for survival using Cox regression model.RESULTS: The median follow-up was 28 mo (1-72 mo). Response rates were calculated for the TACE group and chemotherapy group, being 35.7% and 7.1%,respectively. The difference was significant. The one-, two- and three-year Survival rates for the TACE group were 63.04%, 30.35%, and 13.01%, and those for the systemic chemotherapy group were 33.88%, 11.29%, and 0%. According to univariate analysis, variables significantly associated with survival were the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight. Other factors such as age, the intervals between the primary to the metastases, the maximal diameter of the liver metastases, the number of liver metastases, extrahepatic metastasis showed no prognostic significances. These factors mentioned above such as the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight were also independent factors in multivariate analysis.CONCLUSION: TACE treatment of liver metastases from breast cancer may prolong survival in certain patients. This approach offers new promise for the curative treatment of the patients

    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.

    The biology of colorectal cancer differs according to itsitss location within the large intestine. A report publishedinpublished inin a previous issue of World Journal of Gastroenterology (November 2010) evaluated the importance of tumor location as a risk factor for lymph node metastasis in colorectal cancer, and showed that rectal cancer is prone to metastasize to lymph nodes as compared with colon cancer. However, in order to conclude that the tumor location is independently associated with the occurrence of lymph node metastasis, it is necessary to consider a selection bias or other patient- and tumor-related factors carefully.

    Bone scintigraphy (BS) has been used extensively for many years for the diagnosis of bone metastases despite its low specificity and significant rate of equivocal lesions. {sup 18}F-Fluoride PET/CT has been proven to have a high sensitivity and specificity in the detection of malignant bone lesions, but its effectiveness in patients with inconclusive lesions on BS is not well documented. This study evaluated the ability of {sup 18}F-fluoride PET/CT to exclude bone metastases in patients with various malignant primary tumours and nonspecific findings on BS. We prospectively studied 42 patients (34-88 years of age, 26 women) with different types of tumour. All patients had BS performed for staging or restaging purposes but with inconclusive findings. All patients underwent {sup 18}F-fluoride PET/CT. All abnormalities identified on BS images were visually compared with their appearance on the PET/CT images. All the 96 inconclusive lesions found on BS images of the 42 patients were identified on PET/CT images. {sup 18}F-Fluoride PET/CT correctly excluded bone metastases in 23 patients (68 lesions). Of 19 patients (28 lesions) classified by PET/CT as having metastases, 3 (5 lesions) were finally classified as free of bone metastases on follow-up. The sensitivity, specificity, and positive and negative predictive values of {sup 18}F-fluoride PET/CT were, respectively, 100 %, 88 %, 84 % and 100 % for the identification of patients with metastases (patient analysis) and 100 %, 82 % and 100 % for the identification of metastatic lesions (lesion analysis). The factors that make BS inconclusive do not affect {sup 18}F-fluoride PET/CT which shows a high sensitivity and negative predictive value for excluding bone metastases even in patients with inconclusive conventional BS.

    Peritoneal Carcinomatosis (PC) from metastasization of Gastric Cancer (GC), either present at ifrst diagnosis of GC or as recurrence, is considered a fatal disease with no hope of deifnitive cure. Although newer agents like S1 and docetaxel have shown some promise, the median overall survival with the current ifrst line chemotherapy is only 8 to 14 months, and is not greatly improved by adding targeted therapy. A multi-modal approach with cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed along the last two decades in order to tackle this problem. It’s an aggressive, combined treatment still under investigation. Studies coming from Europe and Far East reported long-term survival with 5-year survival rates up to nearly 25% in case of complete cytoreduction. Prophylactic/adjuvant setting is the most evidence-based indication for HIPEC in advanced-stage GC patients without PC, in order to prevent peritoneal recurrence and to improve overall survival. The rationale for immuno treatment in patients with gastric PC is strong. A randomized phase II study, combining complete CRS with intraperitoneal catumaxomab is on-going. The detection of free peritoneal cancer cells is the more realistic and practical way for the identiifcation of patients at risk of carcinomatosis after surgery. The routine use of techniques of molecular detection in peritoneal washing appears to be the more sensitive method. Such patients are potential candidate for multimodal and locoregional treatments in order to prevent the peritoneal recurrence.

    The bone is among the most common sites of metastasis in patients with lung cancer. Over 30%-40% of lung cancers can develop bone metastasis, and no effective therapeutic methods exist in clinic cases. Wnt/β-catenin signaling and Dickkopf1 (DKK1) play important roles in the progression of lung cancer, which preferentially metastasizes to the skeleton. However, the role of DKK1 in osteotropism of small cell lung cancer (SCLC) remains to be elucidated. This study aimed to define the role of DKK1 in SCLC bone metastasis and investigate the underlying mechanisms. Our results demonstrated that the expression level of DKK1 was dramatically higher in bone metastatic SCLC cells (SBC-5 cell line) compared with that in cells without bone metastatic ability (SBC-3 cell line). Therefore, we hypothesized that DKK1 was involved in the bone metastasis of SCLC. We then suppressed the DKK1 expression in SBC-5 cells by RNAi and found that downregulation of DKK1 can inhibit cell proliferation, colony formation, cell migration, and invasion, but increase the apoptosis rate. Downregulation of DKK1 did not affect the cell cycle progression of SBC-5 cells in vitro. In vivo, downregulated DKK1 in SBC-5 cells resulted in attenuated bone metastasis. These results indicated that DKK1 may be an important regulator in bone metastases of SCLC, and targeting DKK1 may be an effective method to prevent and treat skeleton metastases in SCLC cases.

    Full Text Available BACKGROUND: Brain metastases occur commonly in patients with lung cancer. Small vessel ischemic disease is frequently found when imaging the brain to detect metastases. We aimed to determine if the presence of small vessel ischemic disease (SVID of the brain is protective against the development of brain metastases in lung cancer patients. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort of 523 patients with biopsy confirmed lung cancer who had received magnetic resonance imaging of the brain as part of their standard initial staging evaluation was reviewed. Information collected included demographics, comorbidities, details of the lung cancer, and the presence of SVID of the brain. A portion of the cohort had the degree of SVID graded. The primary outcome measure was the portion of study subjects with and without SVID of the brain who had evidence of brain metastases at the time of initial staging of their lung cancer.109 patients (20.8% had evidence of brain metastases at presentation and 345 (66.0% had evidence of SVID. 13.9% of those with SVID and 34.3% of those without SVID presented with brain metastases (p<0.0001. In a model including age, diabetes mellitus, hypertension, hyperlipidemia, and tobacco use, SVID of the brain was found to be the only protective factor against the development of brain metastases, with an OR of 0.31 (0.20, 0.48; p<0.001. The grade of SVID was higher in those without brain metastases. CONCLUSIONS/SIGNIFICANCE: These findings suggest that vascular changes in the brain are protective against the development of brain metastases in lung cancer patients.

    Objective:To explore the role and significance of the joint detection of serum alkaline phosphatase (ALP) and osteocalcin in prostate cancer bone metastases.Methods:A total of 87 cases of prostate cancer patients were diagnosed by radionuclide bone imaging, and 51 cases of them were included in the bone metastases group, while the other 36 cases were selected as the non-metastases group. Serum levels of ALP and osteocalcin of all patients were detected. The sensitivity, specificity, accuracy, likelihood ratio and the predictive value of patients in the two groups were analyzed. The sensitivity and specificity of the combined detection of ALP and osteocalcin and their expression levels in different bone metastases degrees were analyzed.Results:Serum ALP and osteocalcin levels of patients in metastases group were higher than those in non-metastases group and normal control group. In non-metastases group, the ALP level was higher than that in normal control group, while its osteocalcin level was lower than that in control group (P<0.05); The sensitivities of ALP and osteocalcin were 77.2% and 70.6%, respectively, and their specificities were 61.1% and 54.6%, respectively. The sensitivity and specificity became 93.3% and 82.33% in combined detection of ALP and osteocalcin, which was significantly higher than the single detection (P<0.05). The expression levels of ALP and osteocalcin increased with the increase of the metastases degrees (P<0.05). Conclusions:Combined detection of ALP and osteocalcin can be used in the early diagnosis of prostate cancer with improved diagnostic efficiency.

    Intact bone tissue exhibits a characteristic anisotropic microstructure derived from collagen fiber alignment and the related c-axis orientation of apatite crystals, which govern the mechanical properties of bone tissue. In contrast, tumor-invaded bone exhibits a disorganized, less-aligned microstructure that results in severely disrupted mechanical function. Despite its importance both in basic principle and in therapeutic applications, the classical understanding of bone metastasis is limited to alterations in bone mass regulated by metastatic cancer cells. In this study, we demonstrate a novel mechanism underlying the disruption of bone tissue anisotropy in metastasized bone. We observed that direct attack by cancer cells on osteoblasts induces the less-organized osteoblast arrangement. Importantly, the crystallographic anisotropy of bone tissue is quantitatively determined by the level of osteoblast arrangement. Osteoblast arrangement was significantly disrupted by physical contact with cancer cells such as osteolytic melanoma B16F10, breast cancer MDA-MB-231, and osteoblastic prostate cancer MDA-PCa-2b cells. The present findings demonstrate that the abnormal arrangement of osteoblasts induced by physical contact with cancer cells facilitates the disorganized microstructure of metastasized bone.

    Liver metastases in colorectal cancer patients decreases the expected 5 year survival rates by a factor close to nine. It is generally accepted that resection of liver metastases should be attempted whenever feasible. This manuscript addresses the optimal therapeutic plan regarding timing of resection of synchronous liver metastases and the use of chemotherapy in combination with resection of synchronous metachronous liver metastases. The aim is to pool all published results in order to attribute a level of evidence to outcomes and identify lacking evidence areas. A systematic search of guidelines, reviews, randomised controlled, observational studies and updating a meta-analysis was performed. Data were extracted and analysed. Data failed to demonstrate an effect of timing of surgery or use of chemotherapy on overall survival. Concomitant resection of liver metastases and the primary tumour may result in lower postoperative morbidity. Systemic peri-operative chemotherapy may improve progression free survival compared to surgery alone.

    Full Text Available Knowledge on lymph node metastases is crucial for the prognosis and treatment of prostate cancer patients. Conventional anatomic imaging often fails to differentiate benign from metastatic lymph nodes. Pelvic lymph node dissection is an invasive technique and underestimates the extent of lymph node metastases. Therefore, there is a need for more accurate non-invasive diagnostic techniques. Molecular and functional imaging has been subject of research for the last decades, in this respect. Therefore, in this article the value of imaging techniques to detect lymph node metastases is reviewed. These techniques include scintigraphy, sentinel node imaging, positron emission tomography/computed tomography (PET/CT, diffusion weighted magnetic resonance imaging (DWI MRI and magnetic resonance lymphography (MRL. Knowledge on pathway and size of lymph node metastases has increased with molecular and functional imaging. Furthermore, improved detection and localization of lymph node metastases will enable (focal treatment of the positive nodes only.

    Full Text Available Neuroblastoma (NB, which arises from embryonic neural crest cells, is the most common extra-cranial solid tumor of childhood. Approximately half of NB patients manifest bone metastasis accompanied with bone pain, fractures and bone marrow failure, leading to disturbed quality of life and poor survival. To study the mechanism of bone metastasis of NB, we established an animal model in which intracardiac inoculation of the SK-N-AS human NB cells in nude mice developed osteolytic bone metastases with increased osteoclastogenesis. SK-N-AS cells induced the expression of receptor activator of NF-κB ligand and osteoclastogenesis in mouse bone marrow cells in the co-culture. SK-N-AS cells expressed COX-2 mRNA and produced substantial amounts of prostaglandin E2 (PGE2. In contrast, the SK-N-DZ and SK-N-FI human NB cells failed to develop bone metastases, induce osteoclastogenesis, express COX-2 mRNA and produce PGE2. Immunohistochemical examination of SK-N-AS bone metastasis and subcutaneous tumor showed strong expression of COX-2. The selective COX-2 inhibitor NS-398 inhibited PGE2 production and suppressed bone metastases with reduced osteoclastogenesis. NS-398 also inhibited subcutaneous SK-N-AS tumor development with decreased angiogenesis and vascular endothelial growth factor-A expression. Of interest, metastasis to the adrenal gland, a preferential site for NB development, was also diminished by NS-398. Our results suggest that COX2/PGE2 axis plays a critical role in the pathophysiology of osteolytic bone metastases and tumor development of the SK-NS-AS human NB. Inhibition of angiogenesis by suppressing COX-2/PGE2 may be an effective therapeutic approach for children with NB.

    We assessed the diagnostic capabilities of SPECT-CT in patients with unclear and suspicious on the secondary lesion with bone scintigraphy background in planar mode (227 patients (mean age - 57 years) with various primary malignancies). All patients underwent planar scintigraphy with 99mTc-labeled phosphates in the "whole body" mode and then - bizonal single-photon-emission computed tomography combined with X-ray computed tomography (SPECT-CT). In patients with the presence of lesions in the skeleton, suspicious on metastases, there was conducted comparison with the data of SPECT-CT. During planar investigation the suspicion on metastases was detected in 41 patients (18%). The use of SPECT-CT allowed excluding metastases in 29 (71%) and confirmed in 7 (17%) of them. In 5 (12%) cases the nature of the changes remained unclear. Thus, in cancer patients with revealed by planar bone scintigraphy unclear or suspicious for metastatic foci in the skeleton, the use of SPECT-CT allowed in most cases (88%) to clarify the nature of these changes.

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

    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.

    Aims Breast cancer (BC) is the most frequent tumour in women, representing 20–30% of all malignancies, and continues to be the leading cause of cancer deaths among European women. Triple-negative (TN) BC biological aggressiveness is associated with a higher dissemination rate, with central nervous system (CNS) metastases common. This study aims to elucidate the association between gene expression profiles of PTGS2, HBEGF and ST6GALNAC5 and the development of CNS metastases in TNBC. Methods This is a case-controlled retrospective study comparing patients (pts) with CNS metastases versus patients without them after adjuvant treatment. The selection of the samples was performed including 30 samples in both case and control groups. Formalin-fixed, paraffin-embedded samples were retrieved from the Hospital 12 de Octubre Biobank. Five 10 µm sections from each FFPE sample were deparaffinised with xylene and washed with ethanol, and the RNA was then extracted with the RecoverAll Kit (Ambion). Gene expression was assessed using TaqMan assays. Results A total of 53 patients were included in the study. The average age was 55 years (range 25–85). About 47 patients (88.67%) had ductal histology and presented high grade (III) tumours (40 patients; 75.47%). Eight women in the case group presented first distant recurrence in the CNS (34.80%), local recurrence (three patients, 13.04%), lungs (two patients; 8.7%), bone (one patient; 4.34%) and other locations (seven patients; 30.38%). In the control group, first distant recurrence occurred locally (six patients; 46.1%), in bone (two patients; 15.4%), lungs (one patient; 7.7%) and other sites (four patients; 23.1%). RNA was successfully obtained from 53 out of 60 samples. PTGS2, HBEGF, and ST6GALNAC5 expression values were not related to metastasis location. Conclusion TN tumours frequently metastasise to the visceral organs, particularly lungs and brain, and are less common in bone. The literature suggests that expression of

    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.

    Purpose: To characterize temporal trends in the application of various bone metastasis fractionations within the United States during the past decade, using the National Cancer Data Base; the primary aim was to determine whether clinical practice in the United States has changed over time to reflect the published randomized evidence and the growing movement for value-based treatment decisions. Patients and Methods: The National Cancer Data Base was used to identify patients treated to osseous metastases from breast, prostate, and lung cancer. Utilization of single-fraction versus multiple-fraction radiation therapy was compared according to demographic, disease-related, and health care system details. Results: We included 24,992 patients treated during the period 2005-2011 for bone metastases. Among patients treated to non-spinal/vertebral sites (n=9011), 4.7% received 8 Gy in 1 fraction, whereas 95.3% received multiple-fraction treatment. Over time the proportion of patients receiving a single fraction of 8 Gy increased (from 3.4% in 2005 to 7.5% in 2011). Numerous independent predictors of single-fraction treatment were identified, including older age, farther travel distance for treatment, academic treatment facility, and non-private health insurance (P<.05). Conclusions: Single-fraction palliative radiation therapy regimens are significantly underutilized in current practice in the United States. Further efforts are needed to address this issue, such that evidence-based and cost-conscious care becomes more commonplace.

    Up to 20% of the patients with colorectal cancer (CRC) will have liver metastases at the time of the diagnosis, and some of these metastases may be missed during preoperative evaluation. While intraoperative ultrasound is considered the gold standard for liver evaluation during primary open CRC...... surgery, laparoscopic ultrasound (LUS) is not performed routinely during laparoscopic CRC surgery. Based on the available literature LUS had a higher detection rate for especially small liver metastases compared to preoperative imaging modalities, but better prospective trials are needed....

    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.

    The annual incidence of new cancer patients in China is about 2 million, 30-40% of which will end up with bone metastasis. Profound study on the preclinical model and early diagnosis of cancer bone metastasis in rats are very significant for the drug development, better understanding and treatment of bone metastases. In order to monitor the process of bone metabolism and early detection of bone metastasis of cancer cells, a technique of 41Ca isotope tracer combined with AMS has been developed and applied in the study on the bone metastasis of cancer cells by rat model. In this work, 3-month-old female Sprague-Dawley (SD) rats were randomly divided into different groups, and tumor cells injected respectively into the tail vein, femoral artery, femoral cavity and the thigh muscle to establish the rat models for bone metastases. The most appropriate model, i.e., the thigh muscle group, was finally adopted in our real metastases experiment. Each rat in this group was intramuscularly (i.m.) injected with 250 μl CaCl2 solution (containing 1.4 mg Ca and 5nCi 41Ca). About 40 days later, the rat mammary gland carcinoma cells (Walker 256) were injected into these rats following the established protocol. After bone metastasis, medicine interventions were performed. The sequential urine and blood samples were collected and analyzed for 41Ca (by AMS) and N-terminal telopeptide (Ntx), respectively. Bone Mineral Density (BMD) values in the femur and the tibia were measured by CT scan. The results of 41Ca/Ca in longitudinal urinary samples can sensitively reveal the skeletal perturbations caused by bone metastasis of rats, suggests that 41Ca might be similarly developed for human use and improve clinical management through the assessment of the curative effect and non-invasive detection of the earliest stages of cancer growth in bone.

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

    AIM: To analyze the risk factors for interval time,number and pattern of hepatic metastases from gastric cancer after radical gastrectomy, and provide evidence for predicting and preventing hepatic metastasis from gastric cancer after radical gastrectomy. METHODS: A retrospective study of 87 patients with hepatic metastasis who underwent radical gastrectomy for gastric cancer from 1996 to 2001. The data was analyzed to evaluate significant risk factors for interval time, number and pattern of hepatic metastases originating from gastric cancer after radical gastrectomy.RESULTS: The size of gastric cancer and lymph node metastases were independently correlated with the interval time of hepatic metastases; the depth of invasion was independently correlated with the number of hepatic metastases; while the depth of invasion and Lauren classification were independently correlated with the pattern of hepatic metastases.CONCLUSION: We evaluated the interval time of hepatic metastases with the size of gastric cancer and lymph node metastases. The depth of invasion could be used to evaluate the number of hepatic metastases, while the depth of invasion and the Lauren classification could be used to evaluate the pattern of hepatic metastases in patients who underwent radical gastrectomy.

    Complement 5a (C5a), a potent immune mediator generated by complement activation, promotes tumor growth; however, its role in tumor metastasis remains unclear. We demonstrate that C5a contributes to tumor metastases by modulating tumor inflammation in hepatic metastases of colon cancer. Colon cancer cell lines generate C5a under serum-free conditions, and C5a levels increase over time in a murine syngeneic colon cancer hepatic metastasis model. Furthermore, in the absence of C5a receptor or upon pharmacological inhibition of C5a production with an anti-C5 monoclonal antibody, tumor metastasis is severely impaired. A lack of C5a receptor in colon cancer metastatic foci reduces the infiltration of macrophages, neutrophils, and dendritic cells, and the role for C5a receptor on these cells were further verified by bone marrow transplantation experiments. Moreover, C5a signaling increases the expression of the chemokine monocyte chemoattractant protein-1 and the anti-inflammatory molecules arginase-1, interleukin 10, and transforming growth factor β, but is inversely correlated with the expression of pro-inflammatory molecules, which suggests a mechanism for the role of C5a in the inflammatory microenvironment required for tumor metastasis. Our results indicate a new and potentially promising therapeutic application of complement C5a inhibitor for the treatment of malignant tumors.

    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.

    2015-01-01

    The present study reports a rare case of bone multicentric epithelioid hemangioendothelioma (EH) involving the upper and lower extremities simultaneously, with visceral involvement of the lung. Osteolytic lesions were first identified in the right distal femur and proximal tibia. Slight increased radionuclide uptake was observed in the right shoulder joint on bone scintigraphy, however, this was ignored, as no clinical symptoms were present. The patient was initially misdiagnosed with multifocal chondroblastoma, and an extra-articular curettage of lesions was performed in the proximal tibia and medial femoral condyle, which was filled with bone cement. The histopathological diagnosis was corrected post-operatively following immunohistochemical analysis, which indicated EH, and subsequently, an amputation of the right leg at thigh level was performed. In addition, multiple lytic lesions in the right shoulder joint and pulmonary metastases were identified on whole-body radiological examination. Radiotherapy was administered to the right shoulder joint, however, the patient refused chemotherapy or further surgery. At 15 months after the initial surgery, the patient currently remains alive. This case indicates that an improved understanding with regard to the clinical features of this disease may prevent misdiagnosis and improve EH treatment. PMID:26137035

    Long-term survival is difficult after manifestation of distant lymph node metastasis following curative resection for advanced gastric cancer. Two patients who achieved long survival with linac therapy after curative treatment of gastric cancer, are reported. Case 1: 45 years old, male. Distal gastrectomy with D2 dissection was carried out for such gastric cancer as L.M, less.Post.Ant, fType 3, T2 (MP), fStage II, on July 13, 1994. As paraaortic lymph nodes metastases was observed with CT examination on October 12, 1995, irradiation therapy using linac was conducted, and CR was achieved. Though Virchow's lymph nodes metastases was followed that episode, PR was achieved with 4,750 cGy of linac therapy. Finally, however, the patient died with metastases to lung and bone on May 19, 2002. Case 2: 62 years old, male. Distal gastrectomy with D2 + No.8p and also No.16b1 interaorticocaval dissection was conducted for such advanced gastric cancers as M, less, fType 3, T3 (SE), fStage III B on June 7, 1995. Paraaortic lymph nodes metastases were observed through CT examination on October 12, 1995. Irradiation therapy using linac resulted in CR. Virchows lymph node metastasis, which appeared on December 12, 1997, was also treated with 5,000 cGy of linac, and CR was also achieved. The patient is surviving today without recurrence.

    Background Morphologic imaging after radiofrequency ablation (RFA) of liver metastases is hampered by an inflammatory response in the ablation margin, making the identification of local tumor progression (LTP) difficult. The aim of this study was to evaluate the efficacy of early 18F-FDG PET/CT scanning to monitor the effectiveness of RFA in colorectal liver metastases.Methods Twelve patients with 20 metastases were treated with RFA for colorectal liver metastases. They underwent PET/CT within 2 weeks before RFA and within 24 hours after RFA (so termed "early PET/CT"). PET/CT was repeated at 1, 3, and 6 months, and then every 6 months after ablation. The standard of reference was based on available clinical and radiological follow-up data.Results Early PET/CT revealed total photopenia in 16 RFA-treated metastases, which were found to be without residual tumor on the final PET/CT scan. Three RFA-treated metastases with focal uptake were identified as local tumor progression, which necessitated further treatment. One RFA-treated metastasis with rim-shaped uptake was regarded as inflammation. The results of the early PET/CT scanning were consistent with the findings of the final follow-up. Conclusions PET/CT performed within 24 hours after RFA can effectively detect whether residual tumor exists for colorectal cancer liver metastases. The results can guide further treatment, and may improve the efficacy of RFA.

    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

    INTRODUCTION: Colorectal carcinoma accounts for 10% of cancer deaths in the Western World, with the liver being the most common site of distant metastases. Resection of liver metastases is the treatment of choice, with a 5-year survival rate of 35%. However, only 5-10% of patients are suitable for resection at presentation. AIMS: To examine the referral pattern of patients with liver metastases to a specialist hepatic unit for resection. METHODOLOGY: Retrospective review of patient\\'s charts diagnosed with colorectal liver metastases over a 10-year period. RESULTS: One hundred nine (38 women, 71 men) patients with liver metastases were included, mean age 61 years; 79 and 30 patients had synchronous and metachronus metastases, respectively. Ten criteria for referral were identified; the referral rate was 8.25%, with a resection rate of 0.9%. Forty two percent of the patients had palliative chemotherapy; 42% had symptomatic treatment. CONCLUSION: This study highlights the advanced stage of colorectal cancer at presentation; in light of modern evidence-based, centre-oriented therapy of liver metastasis, we conclude that criteria of referral for resection should be based on the availability of treatment modalities.

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

    Full Text Available Abstract Background Accurate staging of colorectal cancer (CRC with clinicopathological parameters is important for predicting prognosis and guiding treatment but provides no information about organ site of metastases. Patterns of genomic aberrations in primary colorectal tumors may reveal a chromosomal signature for organ specific metastases. Methods Array Comparative Genomic Hybridization (aCGH was employed to asses DNA copy number changes in primary colorectal tumors of three distinctive patient groups. This included formalin-fixed, paraffin-embedded tissue of patients who developed liver metastases (LM; n = 36, metastases (PM; n = 37 and a group that remained metastases-free (M0; n = 25. A novel statistical method for identifying recurrent copy number changes, KC-SMART, was used to find specific locations of genomic aberrations specific for various groups. We created a classifier for organ specific metastases based on the aCGH data using Prediction Analysis for Microarrays (PAM. Results Specifically in the tumors of primary CRC patients who subsequently developed liver metastasis, KC-SMART analysis identified genomic aberrations on chromosome 20q. LM-PAM, a shrunken centroids classifier for liver metastases occurrence, was able to distinguish the LM group from the other groups (M0&PM with 80% accuracy (78% sensitivity and 86% specificity. The classification is predominantly based on chromosome 20q aberrations. Conclusion Liver specific CRC metastases may be predicted with a high accuracy based on specific genomic aberrations in the primary CRC tumor. The ability to predict the site of metastases is important for improvement of personalized patient management.

    Full Text Available Medications increasing the survival of patients with metastatic castration-refractory prostate cancer (CRPC are lacking today. In the past 3 years, in the pharmaceutical market there have been a few novel drugs to treat progressive prostate cancer. Abiraterone acetate is an androgen synthesis inhibitor, which is also used to increase the survival of patients with metastatic CRPC that progresses after chemotherapy. The results of treatment for metastatic CRPC depend on a number of factors. Visceral metastases are poor predictors of the course of the disease. The results of abiraterone acetate treatment were analyzed in CRPC patients with visceral metastases.

    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).

  6. Influence of the Different Primary Cancers and Different Types of Bone Metastasis on the Lesion-based Artificial Neural Network Value Calculated by a Computer-aided Diagnostic System,BONENAVI, on Bone Scintigraphy Images

    2017-01-01

    Full Text Available Objective(s: BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN and bone scan index (BSI values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, the ANN value provided by BONENAVI may be influenced by the characteristics of bone metastasis. In this study, we aimed to assess the relationship between ANN value and characteristics of bone metastasis. Methods: We analyzed 50 patients (36 males, 14 females; age range: 42–87 yrs, median age: 72.5 yrs with prostate, breast, or lung cancer who had undergone bone scintigraphy and were diagnosed with bone metastasis (32 cases of prostate cancer, nine cases of breast cancer, and nine cases of lung cancer. Those who had received systematic therapy over the past years were excluded. Bone metastases were diagnosed clinically, and the type of bone metastasis (osteoblastic, mildly osteoblastic,osteolytic, and mixed components was decided visually by the agreement of two radiologists. We compared the ANN values (case-based and lesion-based among the three primary cancers and four types of bone metastasis.Results: There was no significant difference in case-based ANN values among prostate, breast, and lung cancers. However, the lesion-based ANN values were the highest in cases with prostate cancer and the lowest in cases of lung cancer (median values: prostate cancer, 0.980; breast cancer, 0.909; and lung cancer, 0.864. Mildly osteoblastic lesions showed significantly lower ANN values than the other three types of bone metastasis (median values: osteoblastic, 0.939; mildly osteoblastic, 0.788; mixed type, 0.991; and osteolytic, 0.969. The possibility of a lesion-based ANN value below 0.5 was 10.9% for bone metastasis in prostate cancer, 12.9% for breast cancer, and 37

    Purpose Summarize current knowledge, critical gaps in knowledge, and recommendations to advance the field of metastatic bone cancer. Experimental Design A multidisciplinary consensus conference was convened to review recent progress in basic and clinical research, assess critical gaps in current knowledge, and prioritize recommendations to advance research in the next 5 years. The program addressed three principal topics: biology of metastasis, preserving normal bone health, and optimizing bone-targeted therapies. Results A variety of specific recommendations were identified as important to advance research and clinical care over the next 5 years. Conclusions Priorities for research in bone biology include characterizing components of the stem cell niche in bone, developing oncogenic immunocompetent animal models of bone metastasis, and investigating the unique contribution of the bone microenvironment to tumor growth and dormancy. Priorities for research in preserving normal bone health include developing methods to measure and characterize disseminating tumor cells, assessing outcomes from the major prevention trials currently in progress, and improving methodologies to assess risks and benefits of treatment. Priorities for optimizing bone-targeted therapies include advancing studies of serum proteomics and genomics to reliably identify patients who will develop bone metastases, enhancing imaging for early detection of bone metastases and early response evaluation, and developing new tests to evaluate response to bone-directed treatments.

    {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

    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

  13. Can the National Health Service Cancer Plan timeline be applied to colorectal hepatic metastases?

    LENUS (Irish Health Repository)

    Jones, Claire

    2012-02-01

    INTRODUCTION: The National Health Service (NHS) Cancer Plan guidelines recommend a maximum 2-week wait from referral to first appointment, and 2 months from referral to treatment for primary cancers. However, there are currently no guidelines available for metastatic disease. In the UK, nearly half of all colorectal cancer patients develop hepatic metastases. Timely, surgical resection offers the potential for cure. The aim of this study was to audit current practice for colorectal liver metastases in a regional hepatobiliary unit, and compare this to the NHS Cancer Plan standards for primary disease. PATIENTS AND METHODS: A retrospective review of the unit\\'s database was performed for all hepatic metastases referrals from January 2006 to December 2008. The dates of referral, first appointment, investigations and initiation of treatment, along with patient\\'s age and sex, were recorded on Microsoft Excel and analysed. Time was expressed as mean +\\/- SD in days. RESULTS: A total of 102 patients with hepatic metastases were identified. Five were excluded due to incomplete data. The average time from referral to first appointment was 10.6 +\\/- 9.4 days and the average time from referral to treatment was 38.5 +\\/- 28.6 days. Seventy-five (72.7%) had surgical intervention, of whom 37 also had chemotherapy. CONCLUSIONS: The data compare favourably to the NHS Cancer Plan guidelines for primary malignancy, demonstrating that a regional hepatobiliary unit is capable of delivering a service for colorectal liver metastases that adheres to the NHS Cancer Plan. Therefore, the NHS Cancer Plan can be applied to this cohort.

    Full Text Available Carmelo Caldarella,1 Giorgio Treglia,2 Alessandro Giordano,1 Luca Giovanella2 1Institute of Nuclear Medicine, Catholic University of the Sacred Heart, Rome, Italy; 2Department of Nuclear Medicine and PET/CT Centre, Oncology Institute of Southern Switzerland, Bellinzona, Switzerland Abstract: Skeletal metastases are very common in prostate cancer and represent the main metastatic site in about 80% of prostate cancer patients, with a significant impact in patients' prognosis. Early detection of bone metastases is critical in the management of patients with recently diagnosed high-risk prostate cancer: radical treatment is recommended in case of localized disease; systemic therapy should be preferred in patients with distant secondary disease. Bone scintigraphy using radiolabeled bisphosphonates is of great importance in the management of these patients; however, its main drawback is its low overall accuracy, due to the nonspecific uptake in sites of increased bone turnover. Positron-emitting radiopharmaceuticals, such as fluorine-18-fluorodeoxyglucose, choline-derived drugs (fluorine-18-fluorocholine and carbon-11-choline and sodium fluorine-18-fluoride, are increasingly used in clinical practice to detect metastatic spread, and particularly bone involvement, in patients with prostate cancer, to reinforce or substitute information provided by bone scan. Each radiopharmaceutical has a specific mechanism of uptake; therefore, diagnostic performances may differ from one radiopharmaceutical to another on the same lesions, as demonstrated in the literature, with variable sensitivity, specificity, and overall accuracy values in the same patients. Whether bone scintigraphy can be substituted by these new methods is a matter of debate. However, greater radiobiological burden, higher costs, and the necessity of an in-site cyclotron limit the use of these positron emission tomography methods as first-line investigations in patients with prostate cancer

    Brain metastases occur in about 10% to 30% of breast cancer patients, which culminates in a poor prognosis. It is, therefore, critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII-tubulin, Nestin, and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII-tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2, and MDA-MB-468), which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells.

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

    Lung cancer frequently develops multiple organ metastases, which thus makes this disease a leading cause of malignancy-related death worldwide. A gender difference is reported to affect the incidence and mortality of lung cancer; however, whether and how the gender difference is involved in lung cancer metastasis is unclear. This study evaluated the gender difference in multiple organ metastases in human small cell lung cancer (SBC-5) cells by using natural killer cell-depleted severe combined immunodeficient mice. Among multiple organ metastases, only bone metastasis formation significantly increased in female mice in comparison to males, while no significant difference was observed in the metastases to the liver and lungs. The suppression of androgen by castration or androgen receptor antagonist treatment in male mice also induced a significant increase of bone metastases. The number of osteoclasts in the bone metastatic lesions was greater in female mice and in mice with androgen suppression than in control male. However, there was no significant difference in the serum concentration of parathyroid hormone-related protein (PTHrP) associated with gender or androgen suppression. An in vitro study also indicated that sex steroid treatment had no effect on the proliferation or PTHrP production in SBC-5 cells. These results indicate that the balance of sex steroids therefore plays an important role in the formation of bone metastasis in small cell lung cancer, and suggests diverse mechanisms of interaction between cancer cells and host cells in the bone microenvironment.

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

    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.

    It is still not clear whether pulmonary resection may have a role in the multidisciplinary management of gastric cancer lung metastases. A systematic literature search was performed to identify all studies published between January 1998 and December 2014 about pulmonary resection of gastric cancer metastases. Ten studies published between 1998 and 2013 were retrieved, including a total of 44 patients. After gastrectomy, median disease-free interval was 35 months. Thirty-eight patients had single lung metastases, whereas six presented with more than one lesion. Median overall survival after lung resection was 45 months, and median disease-free survival was 9 months. Our analysis of the recent literature shows that lung metastasectomy for gastric cancer pulmonary metastases has been reported only in the setting of anecdotic cases or small series of highly selected patients. Lung metastasectomy has no role in the standard management of metastatic gastric patients and may actually be proposed only in individual highly selected cases.

    Therapeutic phosphonate-based radiopharmaceuticals radiolabeled with beta, alpha and conversion electron emitting radioisotopes have been investigated for the targeted treatment of painful bone metastases for >35years. We performed a systematic literature search and focused on the pharmaceutical development, preclinical research and early human studies of these radiopharmaceuticals. The characteristics of an ideal bone-targeting therapeutic radiopharmaceutical are presented and compliance with these criteria by the compounds discussed is verified. The importance of both composition and preparation conditions for the stability and biodistribution of several agents is discussed. Very few studies have described the characterization of these products, although knowledge on the molecular structure is important with respect to in vivo behavior. This review discusses a total of 91 phosphonate-based therapeutic radiopharmaceuticals, of which only six agents have progressed to clinical use. Extensive clinical studies have only been described for (186)Re-HEDP, (188)Re-HEDP and (153)Sm-EDTMP. Of these, (153)Sm-EDTMP represents the only compound with worldwide marketing authorization. (177)Lu-EDTMP has recently received approval for clinical use in India. This review illustrates that a thorough understanding of the radiochemistry of these agents is required to design simple and robust preparation and quality control methods, which are needed to fully exploit the potential benefits of these theranostic radiopharmaceuticals. Extensive biodistribution and dosimetry studies are indispensable to provide the portfolios that are required for assessment before human administration is possible. Use of the existing knowledge collected in this review should guide future research efforts and may lead to the approval of new promising agents.

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

    We describe the clinical and therapeutic course of a 51-year-old woman with HER-2+ breast cancer who developed leptomeningeal (LM) and spinal cord metastases after 8 years of stable disease on combination therapy with intravenous (IV) trastuzumab. Due to progressive CNS disease, intrathecal (IT) trastuzumab was introduced to enhance HER-2+ therapy into the CSF space. A combination HER-2+ targeted approach achieved clinical remission with stable disease in our patient 46 months after she was diagnosed with LM metastases. However, spinal cord C-1 metastasis was not fully controlled with IT trastuzumab, ultimately leading to the patient's respiratory compromise. In our patient, IT trastuzumab immunotherapy improved prognosis and was an effective strategy to manage HER-2+ LM disease. Given alone or alongside other anti-HER-2+ therapeutics with sufficient CNS penetration, IT trastuzumab could extend the lifespan of patients with leptomeningeal and CNS metastases.

    Wnt signaling is critical for tumorigenesis and skeletal remodeling. However, its contribution to the formation of metastatic bone lesions remains poorly defined. One major challenge of unraveling its role in cancer progression is the high complexity of Wnt signaling, which includes numerous ligands, receptors, and inhibitors, with intricate biological effects and specific signaling pathways depending on the cellular context. In this perspective, we summarize the role of the noncanonical Wnt ligand WNT5A in the development and metastatic process of osteotropic cancer entities. We focus on its tumor-suppressive function in breast cancer, tumor promoting effects in melanoma, and ambiguous role in prostate cancer, and discuss potential challenges and opportunities that may be associated with targeting Wnt signaling for cancer therapy and treatment of bone metastases. © 2016 American Society for Bone and Mineral Research.

    Full Text Available Prostate cancer (PCa is the second leading cause of cancer death in men worldwide. Most PCa patients die with osteoblastic bone metastases. What triggers PCa metastasis to the bone and what causes osteoblastic lesions remain unanswered. A major contributor to PCa metastasis is the host microenvironment. In this revew, we address how the primary tumor microenvironment influences PCa metastasis via integrins, extracellular proteases, and transient epithelia-mesenchymal transition (EMT to promote PCa progression, invasion, and metastasis. We discuss how the bone microenvironment influences metastasis; where chemotactic cytokines favor bone homing, adhesion molecules promote colonization, and bone-derived signals induce osteoblastic lesions. Animal models that fully recapitulate human PCa progression from primary tumor to bone metastasis are needed to understand the PCa pathophysiology that leads to bone metastasis. Better delineation of the specific processes involved in PCa bone metastasize is needed to prevent or treat metastatic PCa. Therapeutic regimens that focus on the tumor microenvironment could add to the PCa pharmacopeia.

    Full Text Available Abstract Background Several studies have identified rare genetic variations responsible for many cases of familial breast cancer but their contribution to total breast cancer incidence is relatively small. More common genetic variations with low penetrance have been postulated to account for a higher proportion of the population risk of breast cancer. Methods and Results In an effort to identify genes that influence non-familial breast cancer risk, we tested over 25,000 single nucleotide polymorphisms (SNPs located within approximately 14,000 genes in a large-scale case-control study in 254 German women with breast cancer and 268 age-matched women without malignant disease. We identified a marker on chromosome 14q24.3-q31.1 that was marginally associated with breast cancer status (OR = 1.5, P = 0.07. Genotypes for this SNP were also significantly associated with indicators of breast cancer severity, including presence of lymph node metastases (P = 0.006 and earlier age of onset (P = 0.01. The association with breast cancer status was replicated in two independent samples (OR = 1.35, P = 0.05. High-density association fine mapping showed that the association spanned about 80 kb of the zinc-finger gene DPF3 (also known as CERD4. One SNP in intron 1 was found to be more strongly associated with breast cancer status in all three sample collections (OR = 1.6, P = 0.003 as well as with increased lymph node metastases (P = 0.01 and tumor size (P = 0.01. Conclusion Polymorphisms in the 5' region of DPF3 were associated with increased risk of breast cancer development, lymph node metastases, age of onset, and tumor size in women of European ancestry. This large-scale association study suggests that genetic variation in DPF3 contributes to breast cancer susceptibility and severity.

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

    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

    Bisphosphonates are widely used in the treatment of breast cancer with bone metastases. We report a case of a female with breast cancer presented with a rash around a previous mastectomy site and a discharge lesion on her right chest wall in August 2010. Biopsy of the lesion showed dystrophic calcification and metaplastic bone formation. The patient's history revealed a long term use of zoledronic acid for the treatment of breast cancer with bone metastasis. We stopped the treatment since we believed that the cutaneous dystrophic calcification could be associated with her long term bisphosphonate therapy. Adverse cutaneous events with bisphosphonates are very rare, and dystrophic calcification has not been reported previously. The dystrophic calcification and metaplastic bone formation in this patient are thought to be due to long term bisphosphonate usage. PMID:23956898

    Qualitative and quantitative bone features were determined in nondecalcified and decalcified bone from 20 predetermined bone sites in each of 44 patients who died with castration-resistant prostate cancer (CRPC), some of which received bisphosphonate treatment (BP) in addition to androgen-deprivation therapy (ADT). Thirty-nine of the 44 patients (89%) had evidence of bone metastases. By histomorphometric analysis, these bone metastases were associated with a range of bone responses from osteoblastic to osteolytic with a wide spectrum of bone responses often seen within an individual patient. Overall, the average bone volume/tissue volume (BV/TV) was 25.7%, confirming the characteristic association of an osteoblastic response to prostate cancer bone metastasis when compared with the normal age-matched weighted mean BV/TV of 14.7%. The observed new bone formation was essentially woven bone, and this was a localized event. In comparing BV/TV at metastatic sites between patients who had received BP treatment and those who had not, there was a significant difference (28.6% versus 19.3%, respectively). At bone sites that were not invaded by tumor, the average BV/TV was 10.1%, indicating significant bone loss owing to ADT that was not improved (11%) in those patients who had received BPs. Surprisingly, there was no significant difference in the number of osteoclasts present at the metastatic sites between patients treated or not treated with BPs, but in bone sites where the patient had been treated with BPs, giant osteoclasts were observed. Overall, 873 paraffin-embedded specimens and 661 methylmethacrylate-embedded specimens were analyzed. Our results indicate that in CRPC patients, ADT induces serious bone loss even in patients treated with BP. Furthermore, in this cohort of patients, BP treatment increased BV and did not decrease the number of osteoclasts in prostate cancer bone metastases compared with bone metastases from patients who did not receive BP.

  9. Are primary renal cell carcinoma and metastases of renal cell carcinoma the same cancer?

    2016-05-01

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

    Bone metastases are common among patients with stage IV genitourinary cancers. Most patients with bone metastases develop at least one debilitating and potentially life-limiting skeletal-related event. These events are associated with increased medical expenses and decreased quality of life. Current guidelines recommend screening for bone metastases in men with high-risk prostate cancer, but guidance for screening and treatment of bone metastases from genitourinary cancers varies by country and setting. Several bisphosphonates have been evaluated in the advanced genitourinary cancer setting. Zoledronic acid has demonstrated efficacy in significantly reducing the risk of skeletal-related events in patients with bone metastases from a broad range of solid tumors including prostate, renal and bladder cancers, and is recommended for preserving bone health.

    The annual incidence of new cancer patients in China is about 2 million, 30–40% of which will end up with bone metastasis. Profound study on the preclinical model and early diagnosis of cancer bone metastasis in rats are very significant for the drug development, better understanding and treatment of bone metastases. In order to monitor the process of bone metabolism and early detection of bone metastasis of cancer cells, a technique of {sup 41}Ca isotope tracer combined with AMS has been developed and applied in the study on the bone metastasis of cancer cells by rat model. In this work, 3-month-old female Sprague–Dawley (SD) rats were randomly divided into different groups, and tumor cells injected respectively into the tail vein, femoral artery, femoral cavity and the thigh muscle to establish the rat models for bone metastases. The most appropriate model, i.e., the thigh muscle group, was finally adopted in our real metastases experiment. Each rat in this group was intramuscularly (i.m.) injected with 250 μl CaCl{sub 2} solution (containing 1.4 mg Ca and 5nCi {sup 41}Ca). About 40 days later, the rat mammary gland carcinoma cells (Walker 256) were injected into these rats following the established protocol. After bone metastasis, medicine interventions were performed. The sequential urine and blood samples were collected and analyzed for {sup 41}Ca (by AMS) and N-terminal telopeptide (Ntx), respectively. Bone Mineral Density (BMD) values in the femur and the tibia were measured by CT scan. The results of {sup 41}Ca/Ca in longitudinal urinary samples can sensitively reveal the skeletal perturbations caused by bone metastasis of rats, suggests that {sup 41}Ca might be similarly developed for human use and improve clinical management through the assessment of the curative effect and non-invasive detection of the earliest stages of cancer growth in bone.

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

    Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes.

    Pancreatic cancer patients underwent surgical resection often present distant metastases early after surgery. Detection of circulating tumor cells (CTCs) has been correlated to a worse oncological outcome in patients with advanced pancreatic cancer. The objective of this pilot study is to investigate the possible prognostic role of CTCs in patients undergoing surgery for pancreatic cancer. In 20 patients undergoing pancreatic resection, 10 mL blood sample was collected intraoperatively from both systemic circulation (SC) and portal vein (PV). Blood sample was analyzed for CTCs with CellSearch® system. All patients underwent an oncologic follow-up for at least 3 years, quarterly. CTCs were detected in nine (45%) patients: five patients had CTCs in PV only, three patients in both SC and PV, and one patient in SC only. CTC-positive and CTC-negative patients were similar for demographics and cancer stage pattern. No significant differences were found in both overall and disease-free survival between CTC-positive and CTC-negative patients. At 3-year follow-up, portal vein CTC-positive patients presented a higher rate of liver metastases than CTC-negative patients (53 vs. 8%, p = 0.038). CTCs were found in 45% of the patients. No correlation between CTCs and survival was found. The presence of CTCs in portal vein has been associated to higher rate of liver metastases after surgery.

    Purpose: To elucidate survival times and identify potential prognostic factors in patients with triple-negative (TN) phenotype who harbored brain metastases arising from breast cancer and who underwent stereotactic radiosurgery (SRS). Methods and Materials: A total of 103 breast cancer patients with brain metastases were treated with SRS and then studied retrospectively. Twenty-four patients (23.3%) were TN. Survival times were estimated using the Kaplan-Meier method, with a log-rank test computing the survival time difference between groups. Univariate and multivariate analyses to predict potential prognostic factors were performed using a Cox proportional hazard regression model. Results: The presence of TN phenotype was associated with worse survival times, including overall survival after the diagnosis of primary breast cancer (43 months vs. 82 months), neurologic survival after the diagnosis of intracranial metastases, and radiosurgical survival after SRS, with median survival times being 13 months vs. 25 months and 6 months vs. 16 months, respectively (p < 0.002 in all three comparisons). On multivariate analysis, radiosurgical survival benefit was associated with non-TN status and lower recursive partitioning analysis class at the initial SRS. Conclusion: The TN phenotype represents a significant adverse prognostic factor with respect to overall survival, neurologic survival, and radiosurgical survival in breast cancer patients with intracranial metastasis. Recursive partitioning analysis class also served as an important and independent prognostic factor.

    The liver is one of the commonest sites of metastatic involvement in breast cancer, usually evident as focal lesions on imaging tests. Rarely, the pattern of metastatic spread is so diffuse that it remains radiologically occult. Such patients usually present with signs of hepatic insufficiency without any focal lesions on liver imaging. In such cases, liver biopsy is required to make a definitive diagnosis. We report a case of a 56-year-old postmenopausal woman with metastatic breast cancer who presented with subacute progressive liver failure. Repeated imaging of the liver was normal or non-descript. Liver biopsy finally established the diagnosis of intrasinusoidal metastases from breast cancer.

    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.

    Full Text Available Treatment results of low rectal cancer patient with internal sphincter involvement and synchronous liver metastases is presented. After combined treatment including preoperative targeted therapy, chemotherapy, chemoradiotherapy a synchronous resection of primary tumour and liver metastases was carried out (R0. Synchronous right hepihepatectomy and proctectomy was performed with resection of the deep part of external sphincter, neorectum creation by transverse coloplasty, neoanal sphincter creation using colonic smooth muscle layer without preventive colostomy. A possibility of synchronous plastic sphincter-sparing surgery in metastatic rectal cancer patient with locally advanced tumour is demonstrated. Such treatment allows to remove the risk of primary tumour complications, facilitates further chemotherapy treatment and improves quality of life and long-term treatment outcome.

    We present a case of a 72-year-old man with a common bile duct cancer, who was initially believed to have multiple liver metastases based on computed tomography findings, and in whom magnetic resonance cholangiography (MRC) revealed a diagnosis of bile duct hamartomas. At exploration for pancreaticoduodenectomy, liver palpation revealed disseminated nodules at the surface of the liver. These nodules showed gray-white nodular lesions of about 0.5cm in diameter scattered on the surface of both liver lobes, which were looked like multiple liver metastases from bile duct cancer. Frozen section of the liver biopsy disclosed multiple bile ducts with slightly dilated lumens embedded in the collagenous stroma characteristics of multiple bile duct hamartomas (BDHs). Only two reports have described the MRC features of bile duct hamartomas. Of all imaging procedures, MRC provides the most relevant features for the imaging diagnosis of bile duct hamartomas.

    Of 42 radionuclide bone scans in 35 children with neuroblastoma, 21 were abnormal for the presence of skeletal metastases. Of the 21 abnormal scans, 16 were corroborated by positive bone-marrow biopsy or clinical data. The false-negative and false-positive rates for bone scanning were 4.8% and 9.5%, respectively. Calcification of the primary tumor was seen on pretreatment computed tomographic (CT) scans in 24 (89%) of 27 cases, while only 13 (48%) of 27 were detectable by plain radiographs. Uptake of /sup 99m/Tc methylene diphosphate /sup 99m/Tc-MDP) by the primary tumor occurred in 20 of 27 cases, but correlation between tumor uptake and calcification was not statistically significant. All children with markedly elevated urinary vanillylmandelic acid exhibited primary tumor uptake. Survival was not affected independently by primary tumor uptake.

    Cellular proliferation depends on refilling the tricarboxylic acid (TCA) cycle to support biomass production (anaplerosis). The two major anaplerotic pathways in cells are pyruvate conversion to oxaloacetate via pyruvate carboxylase (PC) and glutamine conversion to α-ketoglutarate. Cancers often show an organ-specific reliance on either pathway. However, it remains unknown whether they adapt their mode of anaplerosis when metastasizing to a distant organ. We measured PC-dependent anaplerosis ...

  6. Large bilateral adrenal metastases in non-small cell lung cancer

    2004-11-01

    Full Text Available Abstract Background The adrenal gland is one of the common sites of metastasis from primary lung cancer. Adrenal metastases are usually unilateral however bilateral adrenal metastases are seen in 10% of all lung cancer patients; of these 2–3% occurs at the initial presentation of non-small cell lung cancer. Secondary tumors can disrupt the structure and function of the adrenal. This can lead to adrenal hemorrhage, which constitutes a life threatening hazard for the patient. Case presentation A 59-year-old male presented with persisting abdominal pain. His initial work-up revealed significant anemia, an invasive process in the right upper lobe of the lung and large masses of heterogeneous texture, with hemorrhagic and necrotic elements in both adrenal glands. A biopsy confirmed it to be a large-cell carcinoma of the lungs. The patient developed severe leukocytosis akin to the paraneoplastic syndrome and died suddenly five days after the administration of chemotherapy. Conclusion Intratumoral hemorrhage is a rare but life threatening complication of adrenal metastases and should be treated as soon as it has been diagnosed. If adrenalectomy is not feasible, combination chemotherapy should be applied as in metastatic disease. For choosing the appropriate chemotherapeutic regimen it is important to accurately achieve the diagnosis.

    Abstract This study aimed to determine the prognostic effects of preoperative chemotherapy for colorectal cancer liver metastasis (CLM). We retrospectively evaluated 2 groups of patients between January 2006 and August 2012. A total of 53 patients who had ≥3 hepatic metastases underwent resection after preoperative chemotherapy (preoperative chemotherapy group), whereas 96 patients who had ≥3 hepatic metastases underwent resection with a curative intent before chemotherapy for CLM (primary resection group). A propensity score (PS) model was used to compare the both groups. The 3-year disease-free survival (DFS) rates were 31.7% and 20.4% in the preoperative chemotherapy and primary resection groups, respectively (log-rank = 0.015). Analyzing 32 PS matched pairs, we found that the DFS rate was significantly higher in the preoperative chemotherapy group than in the primary resection group (3-year DFS rates were 34.2% and 16.8%, respectively [log-rank = 0.019]). Preoperative chemotherapy group patients had better DFSs than primary resection group patients in various multivariate analyses, including crude, multivariable, average treatment effect with inverse probability of treatment weighting model and PS matching. Responses to chemotherapy are as important as achieving complete resection in cases of multiple hepatic metastases. Preoperative chemotherapy may therefore be preferentially considered for patients who experience difficulty undergoing complete resection for multiple hepatic metastases. PMID:28207557

    Detection and segmentation of ovarian cancer metastases have great clinical impacts on women's health. However, the random distribution and weak boundaries of metastases significantly complicate this task. This paper presents a variational framework that combines region competition based level set propagation and image matching flow computation to jointly detect and segment metastases. Image matching flow not only detects metastases, but also creates shape priors to reduce over-segmentation. Accordingly, accurate segmentation helps to improve the detection accuracy by separating flow computation in metastasis and non-metastasis regions. Since all components in the image processing pipeline benefit from each other, our joint framework can achieve accurate metastasis detection and segmentation. Validation on 50 patient datasets demonstrated that our joint approach was superior to a sequential method with sensitivity 89.2% vs. 81.4% (Fisher exact test p = 0.046) and false positive per patient 1.04 vs. 2.04. The Dice coefficient of metastasis segmentation was 92 +/- 5.2% vs. 72 +/- 8% (paired t-test p = 0.022), and the average surface distance was 1.9 +/- 1.5mm vs. 4.5 +/- 2.2mm (paired t-test p = 0.004).

    Full Text Available We present a case of early onset pancreatic cancer related extra-axial brain metastases. A 46-year-old Caucasian non-Jewish nonobese male with a history of PC diagnosed 3 months ago with metastases to the liver, omentum, malignant ascites, and a history of a pulmonary embolism was admitted to the hospital because of a new onset headache, nausea, and vomiting which started 2 days prior to the encounter. Brain MRI was ordered, which showed acute bihemispheric subdural hematomas and left hemispheric extra-axial heterogeneously enhancing lesions consisting with metastatic disease. The patient was started on ondansentron, metoclopramide, and dexamethasone. The cranial irradiation was started, and the patient’s headache and nausea significantly improved. There are only 9 published reports of extra-axial brain metastases related to the pancreatic cancer, whereas our paper is the first such case reported on a patient with epidural metastases and early onset pancreatic cancer.

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

    Rachel Riera

    Full Text Available CONTEXT AND OBJECTIVE: Around 16% to 20% of women with breast cancer have advanced, metastasized breast cancer. At this stage, the disease is treatable, but not curable. The objective here was to assess the effectiveness of lapatinib for treating patients with advanced or metastasized breast cancer. DESIGN AND SETTING: Systematic review of the literature, developed at Centro Paulista de Economia da Saúde (CPES, Universidade Federal de São Paulo (Unifesp. METHOD: Systematic review with searches in virtual databases (PubMed, Lilacs [Literatura Latino-Americana e do Caribe em Ciências da Saúde], Cochrane Library, Scirus and Web of Science and manual search. RESULTS: Only one clinical trial that met the selection criteria was found. This study showed that lapatinib in association with capecitabine reduced the risk of cancer progression by 51% (95% confidence interval, CI: 0.34-0.71; P < 0.001, compared with capecitabine alone, without any increase in severe adverse effects. CONCLUSION: The combination of lapatinib plus capecitabine was more effective than capecitabine alone for reducing the risk of cancer progression. Further randomized clinical trials need to be carried out with the aim of assessing the effectiveness of lapatinib as monotherapy or in association for first-line or second-line treatment of advanced breast cancer.

    Yoonjin Kwak

    Full Text Available BACKGROUND: We aimed to evaluate the clinical significance of microvessel density (MVD, lymphatic vessel density (LVD, and cancer-associated fibroblasts (CAFs in relation to tumor location in advanced colorectal cancer (CRC. METHODS: Using immunohistochemistry, we examined 181 advanced CRC patients for CD31 and D2-40 to measure MVD and LVD, respectively, α-smooth muscle actin (SMA and desmin to identify CAFs, and PTEN to examine genetic changes of CAFs. To evaluate the regional heterogeneity of these properties, we examined tissue from four sites (the center and periphery of the primary cancer, a distant metastasis, and a lymph node metastasis in each patient. RESULTS: MVD, LVD, and CAFs showed significant heterogeneity with respect to the tumor location. LVD was the greatest in the center of the primary cancers and the amount of CAFs was the lowest in distant metastases. In distant metastases, those from the lung had higher LVD and MVD, but fewer CAFs than those from the liver, peritoneum, or ovary. Patients with low MVD and LVD in the center of the primary cancer had worse outcomes and patients with few CAFs in distant metastases and in the primary tumor had a lower survival rate. PTEN expression in CAFs in distant metastases was lost in 11 of 181 CRC patients (6.1%, which was associated with a worse prognosis. CONCLUSIONS: The microenvironment, including cancer-associated microvasculature and fibroblasts, is heterogeneous with respect to the tumor location in CRC patients. Therefore, heterogeneity of microenvironments should be taken into account when managing CRC patients.

    The objective of this project was to systematically determine the prevalence and consequences of pulmonary fibrosis in youth with thyroid carcinoma and lung metastases from Belarus who were treated with radioiodine ({sup 131}I). A total of 69 patients treated for juvenile thyroid carcinoma and lung metastasis with {sup 131}I were assessed. A group of 29 patients without lung metastases and prior {sup 131}I treatment served as controls. The assessments included a CT scan of the lungs, extensive pulmonary function testing and an incremental cycle test to volitional fatigue with measurements of oxygen uptake (V. O{sub 2}), oxygen saturation and alveolar-arterial difference in oxygen partial pressure ({delta}aaO{sub 2}). Five patients with lung metastases showed advanced pulmonary fibrosis on CT scans and also had poorer lung functions compared with the 62 patients with none or minor signs of fibrosis and the 29 controls. Furthermore, these five patients showed lower peak V.O{sub 2}, lower oxygen saturation at peak exercise and higher exercise {delta}aaO{sub 2}. They were younger at the time of cancer diagnosis and had received chemotherapy more frequently than youth with pulmonary metastases who did not develop fibrosis. One of the five patients subsequently died from pulmonary fibrosis. Following the Chernobyl catastrophe, about 7% of children treated with radioiodine for thyroid carcinoma and lung metastases displayed pulmonary fibrosis which was associated with functional impairments. Based on the characteristics of affected individuals, the number of radioiodine courses may have to be limited, especially in young children, and chemotherapy should be avoided. (orig.)

    A patient presented with local pain and voiding difficulties due to a bulky prostatic cancer and diffuse metastatic lesions throughout the pars spongiosa of the urethra. This rare event prompted us to review the literature. Lacking a specific palliative therapy, we developed a technique of intraurethral brachytherapy. With this treatment, we were able to reach a life-lasting palliation. (orig.)

    To prospectively compare the diagnostic accuracy of diffusion-weighted whole body imaging with background whole body signal suppression (DWIBS) with skeletal scintigraphy for the diagnosis and differentiation of skeletal lesions in patients suffering from prostate or breast cancer. A diagnostic cohort of 36 patients was included in skeletal scintigraphy and 1.5 T DWIBS MRI. Based on morphology and signal intensity patterns, two readers each identified and classified independently, under blinded conditions, all lesions into three groups: (1) malignant, (2) unclear if malignant or benign and (3) benign. Finally, for the definition of the gold standard all available imaging techniques and follow-up over a minimum of 6 months were considered. Overall, 45 circumscribed bone metastases and 107 benign lesions were found. DWIBS performed significantly better in detecting malignant skeletal lesions in patients with more than 10 lesions (sensitivity: 0.97/0.91) compared to skeletal scintigraphy (sensitivity: 0.48/0.42). No statistical difference could be found between DWIBS (0.58/0.33) and skeletal scintigraphy (0.67/0.58) in the sensitivity values for malignant skeletal lesions in patients with less than 5 lesions. For benign lesions, scintigraphy scored best with a sensitivity of 0.93/0.87 compared to 0.20/0.13 for DWIBS. Interobserver agreement with Cohen's kappa coefficient was calculated as 0.784 in the case of scintigraphy and 0.663 for DWIBS. With respect to staging, in prostate and breast carcinoma, the DWIBS technique is not superior to skeletal scintigraphy, but ranks equally. However, in the cases with many bone lesions, markedly more metastases could be discovered using the DWIBS technique than skeletal scintigraphy. (orig.)

    Breast cancer liver metastases (BCLM) are not uncommon (about 18% of cases): although some patients have been reported as still living after 25 months, median survival after hormonal- or chemotherapy is 6-14 months. In recent years, new chemotherapy regimens and molecular targeted therapies have given medical oncologists reason to believe that metastatic disease can be eradicated, or at least controlled for prolonged periods. In an attempt to improve survival, consideration has also been given to loco-regional treatments such as hepatic resection and radio-frequency ablation, which have been associated with better outcomes in selected patients. This review considers the role of two loco-regional approaches in a multidisciplinary perspective in the treatment of single or multiple breast cancer metastases limited to the liver. An expanded role for hepatic resection and ablation is being investigated. We assessed available data in the literature to determine their role on survival outcomes. They suggest that loco-regional treatments might be of significant benefit in a selected group of women with BCLM, but the role of these local treatments in multimodality treatment of liver metastases remains controversial. It can generally be said that loco-regional treatments can improve overall survival, with no mortality and less than 20% morbidity in patients at low surgical risk; however, they should only be considered cytoreductive treatments and, as such, always need to be integrated with systemic therapy.

    Full Text Available Abstract Backround Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. Case presentation A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0 sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided. Conclusion Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

    It is now common to resect colorectal cancer by laparoscopic surgery. Hepatectomy has become a standard treatment for patients with colorectal cancer with resectable liver metastases. The resection of liver tumors can now be done partly by laparoscopic surgery. However, metastatic tumors in the right lobe are often difficult to resect laparoscopically. Furthermore, simultaneous resection of the colorectum and liver may also be difficult. In this study, we evaluated a new method to resect both colorectal cancer and liver metastases in the right lobe by laparoscopic surgery. Two cases are presented that underwent total laparoscopic resection of a right lobe tumor, associated with laparoscopic colorectal resection. The metastatic tumor in the right lobe was first resected in the left hemi-prone position. Then, the colorectal cancer was resected in the lithotomy position. The method for resecting the right lobe liver tumor and colorectal cancer was safe and feasible. The mean duration of surgery was 443.5 min, and the mean blood loss was 158 mL. The postoperative course was uneventful. In selected patients, laparoscopic hepatectomy for right lobe synchronous metastatic tumors can be safely performed simultaneously with colorectal surgery.

    Personalized medicine uses genomic information for selecting therapy in patients with metastatic cancer. An issue is the optimal tissue source (primary tumor or metastasis) for testing. We compared the DNA copy number and mutational profiles of primary breast cancers and paired metastases from 23 patients using whole-genome array-comparative genomic hybridization and next-generation sequencing of 365 "cancer-associated" genes. Primary tumors and metastases harbored copy number alterations (CNAs) and mutations common in breast cancer and showed concordant profiles. The global concordance regarding CNAs was shown by clustering and correlation matrix, which showed that each metastasis correlated more strongly with its paired tumor than with other samples. Genes with recurrent amplifications in breast cancer showed 100% (ERBB2, FGFR1), 96% (CCND1), and 88% (MYC) concordance for the amplified/non-amplified status. Among all samples, 499 mutations were identified, including 39 recurrent (AKT1, ERBB2, PIK3CA, TP53) and 460 non-recurrent variants. The tumors/metastases concordance of variants was 75%, higher for recurrent (92%) than for non-recurrent (73%) variants. Further mutational discordance came from very different variant allele frequencies for some variants. We showed that the chosen targeted therapy in two clinical trials of personalized medicine would be concordant in all but one patient (96%) when based on the molecular profiling of tumor and paired metastasis. Our results suggest that the genotyping of primary tumor may be acceptable to guide systemic treatment if the metastatic sample is not obtainable. However, given the rare but potentially relevant divergences for some actionable driver genes, the profiling of metastatic sample is recommended.

    Purpose Surgical resection of isolated hepatic or pulmonary metastases of colorectal cancer is an established procedure, with a 5-year survival rate of about 50%. However, the role of surgical resections in patients with both hepatic and pulmonary metastases is not well established. We aimed to analyze overall survival of these patients and associated factors. Methods Data retrospectively collected from 66 patients who underwent both hepatic and pulmonary metastasectomy after colorectal cancer surgery from August 2002 through August 2013 were analyzed. In univariate analysis, the log-rank test compared patient survival between groups. P < 0.1 was considered indicative of significance. Multivariate analysis of the significance data using a Cox proportional hazard model identified factors associated with overall survival. The synchronous group (n = 57) was defined as patients who had metastasectomy within 3 months from primary colorectal cancer surgery. The remaining nine patients constituted the metachronous group. Results Median follow-up was 126 months from the primary colorectal cancer surgery. The 5-year survival was 73.4%. There was no difference in overall survival between the synchronous and metachronous groups, consistent with previous studies. Distribution (involving one hemiliver or both, P = 0.010 in multivariate analysis) of liver metastases and multiplicity of the pulmonary metastasis (P = 0.039) were predictors of poor prognosis. Conclusion Sequential or simultaneous resection of both hepatic and pulmonary metastasis of colorectal cancer resulted in good long-term survival in selected patients. Thus, an aggressive surgical approach and multidisciplinary decision making with surgeons seems to be justified. PMID:28203555

    To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

    This study examines the Helix pomatia lectin (HPA) binding characteristics of metastases arising from primary breast cancer, and compares HPA binding patterns with binding of Dolichos biflorus lectin (DBA), Limax flavus lectin (LFA), and a monoclonal antibody against the Tn epitope. Of 81 blocks of metastases in a range of tissues, taken at autopsy from 46 individuals, 79% were HPA positive. No site specificity with regard to HPA binding was observed. Both HPA-positive and -negative tumour deposits were seen within a single individual. HPA-positive tumours were commonly negative for binding of sialic acid specific lectin LFA (86% were negative). Binding patterns of alpha-GalNAc specific HPA and DBA, and a monoclonal antibody against Tn epitope (GalNAc-O-Ser/Thr) were markedly different.

    A 76-year-old man insidiously developed diffuse neurological symptoms: cognitive decline, dysphagia, dysphasia and mental disturbance. Computed tomography of the cranium revealed widespread bilateral brain edema and symmetrical bilateral sphenoid wing hyperostosis. Adjacent to the hyperostosis that resembled skull base meningiomas, two separate parenchymatous temporal lobe lesions enhancing with contrast medium were observed. The patient had earlier been diagnosed to have prostatic carcinoma. Dexamethasone therapy resulted in discontinuation of the neurological symptoms. The diagnosis of metastasized adenocarcinoma of the prostate was confirmed histologically on autopsy after a sudden death from pneumonia. Intracranial metastases of prostate cancer may have a predilection site at the sphenoid wing, and can mimic a skull base meningioma. Intracranial spread of prostatic adenocarcinoma should be considered in elderly men as a treatable cause of gradual neurological deterioration, especially if cranial malignancy or hyperostosis is found.

    Metastatic growth by colorectal cancer cells in the liver requires the ability of the cancer cells to interact with the new microenvironment. This interaction results in three histological growth patterns of liver metastases: desmoplastic, pushing, and replacement. In primary colorectal cancer several proteases, involved in the degradation of extracellular matrix components, are up-regulated. In liver metastases, their expression is growth pattern dependent. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a strong prognostic marker in plasma from colorectal cancer patients, with significant higher levels in patients with metastatic disease. We therefore wanted to determine the expression pattern of TIMP-1 in primary colorectal cancers and their matching liver metastases. TIMP-1 mRNA was primarily seen in α-smooth-muscle actin (α-SMA)-positive cells. In all primary tumors and liver metastases with desmoplastic growth pattern, TIMP-1 mRNA was primarily found in α-SMA-positive myofibroblasts located at the invasive front. Some α-SMA-positive cells with TIMP-1 mRNA were located adjacent to CD34-positive endothelial cells, identifying them as pericytes. This indicates that TIMP-1 in primary tumors and liver metastases with desmoplastic growth pattern has dual functions; being an MMP-inhibitor at the cancer periphery and involved in tumor-induced angiogenesis in the pericytes. In the liver metastases with pushing or replacement growth patterns, TIMP-1 was primarily expressed by activated hepatic stellate cells at the metastasis/liver parenchyma interface. These cells were located adjacent to CD34-positive endothelial cells, suggesting a function in tumor-induced angiogenesis. We therefore conclude that TIMP-1 expression is growth pattern dependent in colorectal cancer liver metastases.

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

    A number of studies have demonstrated that bone scintigraphy has high sensitivity and efficacy in the early detection of bone metastases from several tumours, including breast cancer. Bone scintigraphy is the most definitive tool for diagnosing and monitoring metastatic spread of breast cancer. However, in the past decade there has been a wide debate on its impact on survival time, morbidity and quality of life. Worldwide economic restrictions and these studies have led to the adoption of an almost minimalist policy for breast cancer follow-up using evidence-based guidelines. The recommended breast cancer surveillance testing includes only a few procedures (history, physical and breast self-examination, patient education on symptoms, pelvic examination). The routine use of additional tests, such as blood cell count, tumour markers, liver ultrasonography, bone scan and chest X-rays, is not recommended. Accordingly, scintigraphy should be reserved for a limited number of patients. On the other hand, early diagnosis of bone involvement may reduce the risk of skeletal related events, thus leading to a significant improvement in quality of life. Furthermore, new drugs (e.g. bisphosphonates) can now delay the onset of bone metastasis and reduce the number of patients who experience skeletal complications. In conclusion, the evidence of the clinical usefulness of bone scintigraphy (to allow early planning of new treatments in advanced disease) has to be re-evaluated, possibly by large randomised prospective trials.

    From a murine breast cancer cell line, 4T1, we established a subclone, 4T1.3, which consistently metastasizes to bone upon its injection into the mammary fat pad. 4T1.3 clone exhibited similar proliferation rate and migration capacity as the parental clone. However, the intra-bone injection of 4T1.3 clone caused larger tumors than that of the parental cells, accompanied with increases in fibroblast, but not osteoclast or osteoblast numbers. 4T1.3 clone displayed an enhanced expression of a chemokine, CCL4, but not its specific receptor, CCR5. CCL4 shRNA-transfection of 4T1.3 clone had few effects on its in vitro properties, but reduced the tumorigenicity arising from the intra-bone injection. Moreover, intra-bone injection of 4T1.3 clone caused smaller tumors in mice deficient in CCR5 or those receiving CCR5 antagonist than in wild-type mice. The reduced tumor formation was associated with attenuated accumulation of CCR5-positive fibroblasts expressing connective tissue growth factor (CTGF)/CCN2. Tumor cell-derived CCL4 could induce fibroblasts to express CTGF/CCN2, which could support 4T1.3 clone proliferation under hypoxic culture conditions. Thus, the CCL4-CCR5 axis can contribute to breast cancer metastasis to bone by mediating the interaction between cancer cells and fibroblasts in bone cavity.

    A 66-year-old woman was referred to our hospital with a right renal tumor in October 2010. In 1984, she underwent a mastectomy because of left breast cancer. In 2006, she underwent a lobectomy because of right lung cancer. A follow-up computed tomography of the lung cancer revealed a right renal tumor which extended to the right quadratus lumborum muscle. An exploratory laparotomy was performed and the tumor was found to be malignant by an intra-operative examination. Then, we performed a right radical nephrectomy together with the excision of quadratus lumborum muscle. Pathological examination revealed breast cancer metastasized to the pararenal fat. We could not find any invasion of the tumor into the renal parenchyma. We followed her for 2 months after the operation without any evidence of recurrence, but she suddenly expired due to an unrelated accident.

    Full Text Available Background: C-Myc, a well-known oncogene located on 8q24.12–q24.23, is often amplified and over-expressed in both primary and metastasizing colorectal cancer. In addition, PRL-3 (also known as PTP4A3, a tyrosine phosphatase located on 8q24.3, is amplified in colorectal cancer metastasis. Beside PRL-3 and c-myc, other oncogenes located on the 8q23–24 region might be involved in this process. Therefore, the present study aims to correlate DNA copy number status of a series of genes at 8q23–24 in colorectal cancer at high resolution in correlation to metastatic disease. Materials and Methods: Thirty-two cases of colorectal cancer, 10 stage B1, 10 B2 and 12 D (Astler–Coller with their corresponding liver metastasis and one colorectal cell line (colo205, previously analyzed by array-CGH, were included in this study. A chromosome 8 specific MLPA probe mixture was used to analyze the presence of DNA copy number changes. The probe mixture contained 29 probes covering 25 genes on chromosome 8, as well as 6 control probes on other chromosomes. Results and Discussion: MLPA results obtained of the colo205 colorectal cell line were comparable with previous array-CGH results, thus validating the MLPA probe mixture. Astler–Coller B1 and B2 colorectal cancers differed significantly in DNA copy number of the genes, MOS (p = 0.04, MYC (p = 0.007, DDEF1 (p = 0.004, PTK2 (p = 0.02 and PTP4A3 (p = 0.04. When comparing these with Astler–Coller D primary tumors, significant differences were seen for several genes as well (MYC (p < 0.000, DDEF1 (p < 0.000, SLA (p < 0.000, PTK2 (p < 0.000, PTP4A3 (p = 0.002, and RECQL4 (p = 0.01. When comparing primary Astler–Coller D tumors and their corresponding liver metastases, a similar pattern of gains and losses was observed. Most of the liver metastases showed higher DNA copy number ratios than the corresponding primary tumors, but this difference was only significant for TPD52 (p = 0.02 and EIF3S6 (p = 0

    Tumour metastasis is a complex process involving reciprocal interplay between cancer cells and host stroma at both primary and secondary sites, and is strongly influenced by microenvironmental factors such as hypoxia. Tumour-secreted proteins play a crucial role in these interactions and present strategic therapeutic potential. Metastasis of breast cancer to the bone affects approximately 85% of patients with advanced disease and renders them largely untreatable. Specifically, osteolytic bone lesions, where bone is destroyed, lead to debilitating skeletal complications and increased patient morbidity and mortality. The molecular interactions governing the early events of osteolytic lesion formation are currently unclear. Here we show hypoxia to be specifically associated with bone relapse in patients with oestrogen-receptor negative breast cancer. Global quantitative analysis of the hypoxic secretome identified lysyl oxidase (LOX) as significantly associated with bone-tropism and relapse. High expression of LOX in primary breast tumours or systemic delivery of LOX leads to osteolytic lesion formation whereas silencing or inhibition of LOX activity abrogates tumour-driven osteolytic lesion formation. We identify LOX as a novel regulator of NFATc1-driven osteoclastogenesis, independent of RANK ligand, which disrupts normal bone homeostasis leading to the formation of focal pre-metastatic lesions. We show that these lesions subsequently provide a platform for circulating tumour cells to colonize and form bone metastases. Our study identifies a novel mechanism of regulation of bone homeostasis and metastasis, opening up opportunities for novel therapeutic intervention with important clinical implications.

    BACKGROUND: Prognostic markers of bone metastatic clear cell renal cell cancer (ccRCC) are poorly established. We tested prognostic value of HIF1β/HIF2β and their selected target genes in primary tumors and corresponding bone metastases. RESULTS: Expression of HIF2β was lower in mRCC both at m......RNA and protein level in 59 non-metastatic ccRCCs (nmRCC), 40 bone metastatic primary ccRCCs (mRCC) and 55 corresponding bone metastases. Results were validated in 399 ccRCCs from the TCGA project. CONCLUSIONS: We identified HIF2β protein as an independent marker of the metastatic potential of ccRCC, however...

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

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

    The bone scan continues to be recommended for both the staging and therapy response assessment of skeletal metastases from prostate cancer. However, it is widely recognised that bone scans have limited sensitivity for disease detection and is both insensitive and non-specific for determining treatment response, at an early enough time point to be clinically useful. We, therefore, review the evolving roles of nuclear medicine and radiology for this application. We have reviewed the published literature reporting recent developments in imaging bone metastases in prostate cancer, and provide a balanced synopsis of the state of the art. The development of single-photon emission computed tomography combined with computed tomography has improved detection sensitivity and specificity but has not yet been shown to lead to improvements in monitoring therapy. A number of bone-specific and tumour-specific tracers for positron emission tomography/computed tomography (PET/CT) are now available for advanced prostate cancer that show promise in both clinical settings. At the same time, the development of whole-body magnetic resonance imaging (WB-MRI) that incorporates diffusion-weighted imaging also offers significant improvements for detection and therapy response assessment. There are emerging data showing comparative SPECT/CT, PET/CT, and WB-MRI test performance for disease detection, but no compelling data on the usefulness of these technologies in response assessment have yet emerged.

    Full Text Available Abstract Introduction A first metastasis to the hand is extremely rare. Usually, an acrometastasis is a sign of very advanced disease, with the presence of previous multiple metastases elsewhere. The present paper is one of the very few case reports of first metastatic location to carpal bones. To date, only Lederer et al., in 1990, and Song and Yao in 2012, have described a metastasis to the trapezium from lung cancer. Case presentation A 74-year-old Caucasian man was submitted to several physical examinations for thumb pain. The first diagnosis was tendonitis and the second diagnosis was thumb carpometacarpal osteoarthritis. Only when the patient was admitted to an internal medicine department for deterioration of his general condition and an enormous mass on his left hand was an open biopsy performed. It revealed a metastasis from large-cell lung carcinoma. A total-body scintigraphy and total-body computed tomography scan were negative for other secondary locations. The patient underwent an amputation at the distal third of the forearm. Conclusion Less than 20 case reports are available in the literature dealing with metastases to carpal bones. Very few cases are described as carpal metastases in the absence of other previous metastases, and only two articles, before the present one, have reported a metastasis to the trapezium. This case report teaches us two things: first, patient adherence to follow-up is extremely important; and, second, a thorough examination of diagnostic findings needs to be carried out at all times.

    The mechanisms that guide organ-specific metastases are not fully established. The aberrant expression of carbohydrates may play a fundamental role in defining the molecular mechanisms for metastases to distant organs and facilitate positive interactions within the target organ. The purpose of the present study was to determine the glycomic profile of a variant of the MDA-MB-231 breast cancer cell line that colonizes the bone and to ascribe mechanistic functions mediated by carbohydrates that might correlate with clinical bone metastases. The carbohydrate expression profiles of osteolytic MDA-MET breast cancer cells and non-osteolytic parental MDA-MB-231 cells were determined. MDA-MET cells were derived from MDA-MB-231 cells by in vivo selection of metastatic bone lesions following intracardiac inoculation. The two related breast cancer cell lines expressed distinct carbohydrate profiles; MDA-MET cells displayed an increased expression of alpha (2,6) linked sialic acid, N-beta1-6 GlcNAc, and sialylated Lewis-A antigen, and decreased expression of Galbeta1,3GalNAc as detected using a combination of lectins and anti-carbohydrate antibodies. Microarray analysis demonstrated an increased expression of glycosyltransferase genes, correlative for the distinct glycomic phenotype. The altered glycomic phenotypes of MDA-MET cells include effects on the differential binding to bone marrow endothelial cells, enhanced ECM binding and an increase in invasive potential. These data suggest that the glycomic phenotype of MDA-MET cells is associated with a select set of accumulated functions that collectively impact on the bone metastases and bone colonization capacity of breast cancer cells.

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