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

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

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.

2010-06-01

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

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

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.

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

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

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

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

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

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

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

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

Incidence of bone metastases and skeletal-related events in breast cancer patients: A population-based cohort study in Denmark

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

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

Bone metastases from breast cancer at the time or radical mastectomy as detected by bone scan. Eight-year follow-up.

1976-07-01

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

Criteria for palliation of bone metastases - Clinical applications

International Nuclear Information System (INIS)

2008-02-01

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

The overall importance of the problem of bone metastases is well recognized by the fact that each year hundreds of thousands of cancer patients develop bone metastases. For example, more than 100 000 new patients develop this condition in the United States of America, although the prevalence is estimated to be double the number of new cases. While it is virtually unknown how many cancer patients in the developing countries develop bone metastases, it is not unrealistic to expect that these figures largely surpass those coming from the developed countries. The reason is simply that more patients in the developing countries are diagnosed as having locally advanced or metastatic cancer that will eventually widely disseminate, including bone metastasis as well. Furthermore, at least some of the cancer patients may survive prolonged periods of time. They can also develop earlier and more severe symptoms than patients harbouring other types (locations) of metastases, emphasizing the importance of the overall problem of painful bone metastases. In addition, there is a big socioeconomic problem of bone metastasis, burdening health care systems worldwide, while having continuous adverse psychological effect on both patients and their families. The management of patients with metastatic bone pain must be a multidisciplinary approach and includes the use of analgesia, radiotherapy, surgery, chemotherapy, hormone treatment, radioisotopes and bisphosphonates.

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

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

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

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

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

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

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

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

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

Pain in castration-resistant prostate cancer with bone metastases: a qualitative study

Directory of Open Access Journals (Sweden)

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

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

We counted the lesions at the time of detection of bone metastases and calculated the rate of increase in the number of bone metastases from changes in serial bone scintigrams, and investigated the usefulness of serial scintigrams as a prognostic indicator in patients with metastatic bone tumors. Subjects were 112 patients with bone metastases from four types of primary lesion: 21 with prostate cancer, 27 breast cancer, 39 lung cancer and 25 stomach cancer. Of these, 18 (prostate), 19 (breast), nine (lung) and eight (stomach) underwent serial bone scintigrams in which bone metastases were first detected and identified as progressing. The numbers of lesions at the time of detection of bone metastases for prostate and stomach cancers were significantly greater than those for lung cancer. The rate of increase in the number of bone metastases for stomach cancer was significantly higher than that for prostate or breast cancers. There was no correlation between the survival time after the detection of bone metastases and the number of lesions at the time of detection in the four types of cancer. However, in prostate cancer, a negative correlation existed between the survival time after the detection of bone metastases and the rate of increase in the number of bone metastases. Thus, in patients with bone metastases from prostate cancer, it appears that the rate of increase in the number of bone metastases, estimated from serial bone scintigrams, was indicative of prognosis.

Bone metastases of differentiated thyroid cancer: the importance of early diagnosis and 131I therapy on prognosis

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

Understanding the Progression of Bone Metastases to Identify Novel Therapeutic Targets

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

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

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

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

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

Among 109 patients with bone metastases reported by Bernier et al., only 4 had both radioiodine uptake and a negative standard radiography examination. Similarly, Durante et al. reported that only 8 of 115 patients had negative radiography findings at presentation. Prognosis may improve if bone metastases are detected earlier. In a recent study, bone metastases were first detected by {sup 131}I scanning in 8 of 16 patients, when complementary radiologic studies were negative. Six of these patients showed an excellent response to {sup 131}I therapy. Today, the nuclear medicine community is well armed for this challenge toward earlier diagnosis. Postsurgery thyroid remnant ablation is more widely used. The {sup 131}I whole body scan associated with thyroid remnant ablation after thyroidectomy has a major role in early diagnosis of functioning distant metastases at a time when complementary imaging techniques (CT, MRI, bone scanning) are often still showing negative findings. Early diagnosis of specific {sup 131}I-avid bone foci will be improved with the advent and generalization of SPECT/CT. When early diagnosis is achieved, repeated {sup 131}I therapy can be effective by targeting not only visible

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

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.

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

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

2015-01-01

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

Importance of antiresorptive therapies for patients with bone metastases from solid tumors

Talreja DB

2012-09-01

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

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

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

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

Paradoxical expression of E-cadherin in prostatic bone metastases.

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

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.

How does iliac crest bone marrow biopsy compare with imaging in the detection of bone metastases in small cell lung cancer?

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

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

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

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

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

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.

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

Breast cancer metastases to the neurocranium might involve the bone, the dura, or the brain parenchyma. The latter location is the far most common. The annual incidence of brain metastases in patients with breast cancer is in the range of 4–11 per 100.000 persons per year. Symptoms and findings mainly result from the location of the lesion. The diagnostic method of choice is magnetic resonance imaging before and after administration of contrast material. Breast cancer brain metastases present...

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.)

2014-01-01

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.

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

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

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.

[Lymph node and distant metastases of thyroid gland cancer. Metastases in the thyroid glands].

Schmid, K W

2015-11-01

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 %).

Osteopoikilosis: A Sign Mimicking Skeletal Metastases in a Cancer Patient

2011-01-01

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.

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

Importance of antiresorptive therapies for patients with bone metastases from solid tumors

International Nuclear Information System (INIS)

Talreja, Draupadi B

2012-01-01

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

General y bone is the most common site of distant. Metastases in beast cancer. Bone scan has an important place in the bone metastases and extent of bone disease and even in the staging and treatment protocol. In study done during 1 year, breast cancer patients and place of bone scan were studied. Every year more than 2000 new patients with cancer are diagnosed and treated in Khorasan state. And more than half of them are treated in Omid Hospital. In the year 2000 a study was done. 1336 new cases were admitted for treatment out of which 164 persons (13%) were breast cancer patients. 100 patients were selected randomly and different factors were studied. How many patients had bone scan and its place in breast cancer? Where is the most common metastatic place and relation with bone scan? The differential diagnosis in positive bone scans and comparing with radiography and patient's clinic were studied. Bone scan is positive in 35% of patients in stage III. Bone is the most common place for distant metastases in breast cancer in patients admitted in Omid hospital in year 2000. Clinical and para clinical study such as radiography and tumour markers were adjusted with bone scan, more in stages III and IV. 39 patients out of 100 studied patients had bone scan. 28 bone scan were adjusted radiologically. In 20 positive bone scan out of 28 patients with metastases 12 patients had bone metastases. Despite 5% positive bone scan in early stages can suggest that bone scan be taken for all patients with breast cancer as a basic step?

Cancer Metastases to Bone: Concepts, Mechanisms, and Interactions with Bone Osteoblasts

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

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

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

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

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.

A 74-year-old man had an endoscopic type 0'-IIc tumor in the upper gastric body on the greater curvature and biopsy showed the tumor to be a well-differentiated adenocarcinoma (Group 5). He was referred to us for endoscopic submucosal dissection (ESD). Endoscopy revealed fold convergency, fold swelling, and fusion of the fold, indicating tumor invasion into the submucosa, which was outside the indications for ESD. In addition, there was an increase of serum bone-type alkaline phosphatase (ALP-III and ALP-IV) and urinary cross-linked N-terminal telopeptide of type I collagen (a bone metabolism marker), while (18)F-fluorodeoxyglucose positron emission tomography showed increased uptake in the left pelvis and Th10, suggesting bone metastases. We first diagnosed gastric cancer with bone metastases; however, the symptoms suggested pathological bone fracture and no bone pain. Therefore, a computed tomography-guided aspiration bone biopsy was performed to exclude the possibility of Paget's disease of bone. Biopsy specimens revealed no tumor and a mosaic pattern. No increased uptake of (18)F-FAMT (L-[3-(18)F] α-methyltyrosine) supported a diagnosis of no bone metastases from gastric cancer. We finally diagnosed gastric cancer accompanied by Paget's disease of bone and performed a laparoscopy-assisted proximal gastrectomy. The pathological diagnosis was U less 0-IIb, and U post 0-IIc ypT1a (M) N0H0P0M0 yp stage IA. In gastric cancer patients with suspected bone metastasis, we also need to consider Paget's disease of bone.

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

OBJECTIVE: In the 10 most common primary types with bone metastases, we aimed to examine survival, further stratifying on bone metastases only or with additional synchronous metastases. METHODS: We included all patients aged 18 years and older with incident hospital diagnosis of solid cancer...... between 1994 and 2010, subsequently diagnosed with BM until 2012. We followed patients from date of bone metastasis diagnosis until death, emigration or 31 December 2012, whichever came first. We computed 1-year, 3-year and 5-year survival (%) and the corresponding 95% CIs stratified on primary cancer...... prostate (34%), breast (22%) and lung (20%). One-year survival after bone metastasis diagnosis was lowest in patients with lung cancer (10%, 95% CI 9% to 11%) and highest in patients with breast cancer (51%, 50% to 53%). At 5 years of follow-up, only patients with breast cancer had over 10% survival (13...

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

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

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

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

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.

Role of denosumab in the management of skeletal complications in patients with bone metastases from solid tumors

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

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

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

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

Objective: To discuss the clinical value of whole body bone imaging on lung cancer bone metastases diagnosis, so as to evaluate the staging of lung cancer patients. Methods: A total of 113 cases of patients diagnosed with lung cancer received whole body imaging, alkaline phosphatase and blood calcium examination. Bone metastasis probability of lung cancer was assessed based on different pathological types. Accuracy rates of bone metastases was compared by whole body bone imaging and suspicious bone metastasis factors (Including one or several items in ostalgia, alkaline phosphatase rising and hypercalcemia). Results The occurrence rate of lung cancer bone metastasis is 36.7%, and the bone metastasis occurrence rate of adenocarcinoma of lung is higher than that of squamous cell lung carcinoma (P < 0.01). Whole body Imaging diagnose of lung cancer bone metastases had sensitivity (92.7%), specificity (83.2%) and accuracy (85.7%). Conclusion: "9"9Tc"m-MDP whole body imaging is a highly sensitive tool to review whole body bone. Lung cancer patients are recommended to receive routine whole body bone imaging. (authors)

Full Text Available Breast cancer metastases to the neurocranium might involve the bone, the dura, or the brain parenchyma. The latter location is the far most common. The annual incidence of brain metastases in patients with breast cancer is in the range of 4–11 per 100.000 persons per year. Symptoms and findings mainly result from the location of the lesion. The diagnostic method of choice is magnetic resonance imaging before and after administration of contrast material. Breast cancer brain metastases present as solid, cystic, or partially cystic lesions with marked contrast enhancement and perilesional edema. The therapeutic option of choice is microsurgical resection whenever possible. Adjuvant treatment includes radiotherapy, radiosurgery, and/or chemotherapy.

Lung cancer is one of the most frequent malignancies, with high mortality rates. It can metastasize in almost all organs, but more often invades hilar nodes, liver, adrenal glands, bones and brain. There are various data on the incidence of lung cancer metastases in the skin. In 1-12% of patients with lung cancer are developed skin metastases. Metastases in the skin may be the first sign of lung cancer. Forty-five years old Albanian male, smoker, was admitted to our department with multiple nodules localized in the skin of the head, neck, back and chest. The nodules measuring 5-15 millimeters in greatest dimension were round and skin-colored, with telangiectasias, firm and tender. They appeared in an eruptive form about two weeks before being admitted at our hospital. In addition, the patient exhibited signs of weight loss, anorexia and fatigue. Excisional biopsy was performed to one of the lesions. Histopathology confirmed metastatic nature of the lesion namely, malignant tumor of neuroendocrine phenotype consistent with small-cell carcinoma. Chest X-ray and computed tomography revealed an expansive process in the 7(th) segment of the left lung, left hilar and mediastinal lymphadenopathy and a suspicious initial secondary deposit in the left adrenal gland. The patient was referred to the department of oncology for further treatment. After the third cycle of chemotherapy, the magnetic resonance imaging revealed brain metastases. The patient passed away four months after the diagnosis of lung cancer first presented with skin metastases. Metastases in skin may be the first sign of lung cancer. Although rare appearing, we should raise suspicion in cases of atypical lesions in the skin not only of the smokers, but also of the non-smokers. Skin metastases from small-cell lung carcinoma are a poor prognostic indicator. The appearance of multiple skin metastases with other internal metastases shorten the survival time.

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.

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

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

To quantitatively analyze bone metastases from prostate cancer and correlate the apparent diffusion coefficients (ADCs) and standardized uptake values (SUVs). Fifty-five patients with biopsy-proven prostate cancer or suspected recurrent prostate cancer were examined with simultaneous [ 18 F] choline Positron emission tomography (PET)/MRI at 3 T. In 11 patients, thirty-two PET-positive bone lesions could be identified that were located in the field-of-view of the Diffusion weighted imaging-sequence. Region-of-interest and volume-of-interest analyses were performed to measure the mean and minimal ADCs and to assess maximum and mean SUVs of every bone lesion. Correlations between maximum and mean SUVs and mean and minimal ADCs were calculated. The SUV max of all lesions was 5.5 ± 3.1 (mean ± SD). The SUV mean was 1.8 ± 0.9. The mean ADC (ADC mean ) of all lesions was 0.67 ± 0.13 x 10 -3 mm 2 /s. The minimal ADC (ADC min ) of all lesions was 0.56 ± 0.14 x 10 -3 mm 2 /s. There was a moderate but significant inverse correlation of SUV max vs. ADC mean with a correlation coefficient of -0.4 (p=0.02). There was also a significant inverse correlation of SUV max vs. ADC min with r=-0.41 (p=0.02). Our initial results demonstrate a moderate but significant inverse correlation between increased choline metabolism and ADC values of bone metastases from prostate cancer. Further research on a multimodality approach using simultaneous PET/MRI in bone metastasis of prostate cancer seems to be justified. (author)

Bone scintiscanning in metastases

Cayla, J.; Basset, J.Y.

1986-01-01

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

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

Contribution of sup(99m)Tc labelled sodium pyrophosphate bone scintigraphy to the diagnosis of bone metastases

1976-01-01

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

Full Text Available The purpose and the objectives of the study were to determine the incidence of metastatic lesions to various parts of the spine, the assessment of the association with other clinical signs of lung cancer (localization, form, histology, degree of differentiation, staging, nature of extraosseous metastasis, to investigate the effect of these parameters on the survi­val of the patients. Material and methods. The study included 1071 patients with lung cancer aged 24 to 86 years. None of the examined patients has been operated previously for lung cancer, and after arriving at a diagnosis, all patients received radiation therapy, 73 % of them — combined radiochemothe­rapy. Results. Metastasis in the vertebral bodies and vertebral joints occurs in 13 % of patients with lung cancer and in 61 % of patients with bone form of the disease, the ratio of the defeat of thoracic, sacral, lumbar and cervical spine was 6 : 4 : 2 : 1. The development of metastases in the spine is mostly associa­ted with the localization of the tumor in the upper lobe of the lung, the peripheral form of the disease, with non-small cell histologic variants (adenocarcinoma and squamous cell carcinoma. The number of metastases in the spinal column directly correlates with the degree of metastatic involvement of the inguinal lymph nodes, abdominal wall and the liver, has an impact on the invasion of lung tumor into the esophagus and the trachea. The life expectancy of the deceased persons with spine metastases is less than that of other patients with the lung cancer, but the overall survival rate in these groups of patients is not very different. Conclusions. Clinical features of lung cancer with metastases in the spine necessitate the development of medical technology of rational radiochemotherapy in such patients.

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

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 %.

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

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

186Re-HEDP for metastatic bone pain in breast cancer patients

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

Technetium 99m pyrophosphate bone scintigraphy in the exploration of breast cancer bone metastases (analysis of 311 examinations)

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

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.

Nieder, Carsten; Dalhaug, Astrid; Pawinski, Adam; Mannsåker, Bård; Haukland, Ellinor

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

Full text: Breast cancer is the most common cancer, affecting women in all developed countries of the world. 60 to 70% of women who die with breast cancer have bone metastases. These metastases are currently detected by means of bone scintigraphy and X-ray examinations. Serial bone scans provide significant prognostic information but the assessment of the treatment response remains a problem as the 'flare phenomena' seen shortly after treatment causes difficulty in interpretation of the bone scan. Moreover, an unchanged bone scan findings do not always indicate poor / absent response to therapy. The assessment of bone marrow regeneration in patients with breast cancer is important because it is the primary site of metastases. The aim of this study was to assess the efficacy of chemotherapy treatment in patients with breast cancer by means of radioimmuno bone marrow scintigraphy. We studied 15 patients (mean age 63 years) with advanced breast cancer (II - III stage) and bone metastases revealed by whole body bone scintigraphy and X-ray examination. All patients were treated with two courses of chemotherapy with FEC (Farmorubicin, Cyclophosphamide and 5-Fuoracil) at an interval of four weeks. After the treatment, all patients underwent bone marrow radioimmuno scintigraphy with AGMoAb BW 250/183 (Granulozyt). The AGMoAb was injected by slow intravenous injection in a dose 0.5 mg labelled with 740 Mbq of Tc-99m in a volume of 2 ml of. The images were obtained between 5 - 6 hours after the injection. Whole body scan was performed in anterior and posterior views under a gamma camera (DIACAM-Siemens) coupled with low energy collimator. Radioimmuno imaging before surgery and chemotherapy showed absence of granulopoeitic bone marrow in many areas of the skeleton coinciding with the bone metastases detected by bone scintigraphy. Radioimmuno imaging performed after chemotherapy demonstrated presence of bone marrow in 8 patients (53%) in areas where it was previously absent

Full text: Breast cancer is one of the most common cancers in women. It is the second most widespread cancer in Mexican women. Among the several methods for diagnosis and follow up of the disease, tumor markers like CA-53 have high sensitivity and specificity. Bone scan is a useful method in the detection of bone metastases. In comparison to other diagnostic modalities, bone scan is more sensitive and less expensive for detection of early bone abnormalities and hence to select an appropriate treatment for better prognosis. In our country, in about 70% of cases diagnosis of breast cancer is made when the disease is in an advanced state - states III and IV. The aim of this study was to evaluate the follow up of breast cancer by bone scans and to correlate these findings with the stage of the disease and other diagnostic modalities. The work was carried out at Mexican General Hospital. A total of 350 patients with breast tumor were included; bone scans were performed in all patients at the time of clinical diagnosis and at every 6 months for a period of 1 to 5 years using an Elscint APEX SP6 HR gamma camera coupled with ultra high resolution collimator. Scan was performed 2-3 hours after intravenous administration of 555-925 MBq of Tc-99m methyl diphosphonate. Tumor classification was made according to TNM criteria. Serum levels of alkaline phosphates, carcino-embrionic antigen (CEA) and Ca 53 were also measured on the same day. Fifty-one patients confirmed to have a diagnosis of benign breast were excluded from the study group. Of the remaining 299 patients, 89 (39%) were between 41 years to 50 years, 69 between 51 to 60 years. The clinical stage most commonly observed was stage III (n=164, 54%) followed by stage II (25%). In 59.5% of patients, scintigraphy showed bone metastasis. Four patients with bone metastases showed regression and 42 (14%) with negative scans became positive on follow up bone scans. Ninety-three patients were free of bone metastases during all

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

Full Text Available In contrast to bone scan and computed tomography (CT, which depend on osteoblastic response to detect bone metastasis, whole-body magnetic resonance imaging (WB-MRI may be able to directly detect viable tumors. A 75-year-old male who had progressive metastatic prostate cancer during primary androgen deprivation therapy was referred to our hospital. Although bone scan and CT showed multiple bone metastases, WB-MRI suggested nonviable bone metastasis and viable tumor of the primary lesion. Prostate needle biopsy demonstrated viable prostate cancer cells from 10 of 12 cores. In contrast, CT-guided needle biopsy from bone metastasis of the lumbar vertebra revealed no malignant cells. Based on these findings, we reasoned that viable tumor cells inducing disease progression may primarily exist in the primary lesions and not in the metastatic lesions, and combined prostate radiotherapy and systemic hormonal therapy resulted in successful clinical response and disease control. The use of WB-MRI to detect viable disease lesions may enable us to design optimal treatment strategies for patients with metastatic castration-resistant prostate cancer.

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

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

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

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

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

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

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.

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).

Bone metastases are frequent complications of breast cancer. Recent literature implicates multiple chemokines in the formation of bone metastases in breast cancer. However, the molecular mechanism of metastatic bone disease in breast cancer remains unknown. We have recently made the novel observation of the BST2 protein expression in human breast cancer cell lines. The purpose of our present study is to investigate the expression and the role of BST2 in bone metastatic breast cancer. cDNA microarray analysis was used to compare the BST2 gene expression between a metastatic to bone human breast cancer cell line (MDA-231BO) and a primary human breast cancer cell line (MDA-231). The BST2 expression in one bone metastatic breast cancer and seven non-bone metastatic breast cancer cell lines were also determined using real-time RT-PCR and Western blot assays. We then employed tissue array to further study the BST2 expression in human breast cancer using array slides containing 20 independent breast cancer tumors that formed metastatic bone lesions, 30 non-metastasis-forming breast cancer tumors, and 8 normal breast tissues. In order to test the feasibility of utilizing BST2 as a serum marker for the presence of bone metastasis in breast cancer, we had measured the BST2 expression levels in human serums by using ELISA on 43 breast cancer patients with bone metastasis, 43 breast cancer patients without bone metastasis, and 14 normal healthy controls. The relationship between cell migration and proliferation and BST2 expression was also studied in a human breast recombinant model system using migration and FACS analysis. The microarray demonstrated over expression of the BST2 gene in the bone metastatic breast cancer cell line (MDA-231BO) compared to the primary human breast cancer cell line (MDA-231). The expression of the BST2 gene was significantly increased in the bone metastatic breast cancer cell lines and tumor tissues compared to non-bone metastatic breast cancer

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

Objective: To evaluate the large field diffusion weighted imaging (DWI) (from head vertex to lower leg) in detection of bone metastases from prostate cancer. Methods: One hundred and sixty- six consecutive patients who were suspected of prostate cancer received pelvic MRI and large field diffusion weighted imaging examination. Forty-nine of them underwent bone scintigraphy within one month of the examination of large field DWI. The images were double-blindly evaluated without the knowledge of the pathology result. Conventional MR T 1 and fat saturation T 2 weighted images were taken as standard for the diagnosis of bone metastasis. The sensitivity, specificity, and area under curve between large field DWI and bone scintigraphy were compared with McNemar test. Five patients with bone metastases exceeding 10 per patient were excluded in the lesion-by-lesion analysis. Results: Ten of the 49 patients were diagnosed as bone metastases. The diagnosis of bone metastasis were made in 15 patients by large field DWI and in 17 patients by bone scintigraphy. With patient number as study units (n=49), the diagnostic sensitivity of bone metastases with large field DWI and bone metastases were both 100% (10/10), and specificity were 87.2% (34/39) vs. 82.1% (32/39), respectively. ROC study showed the area under curve (AUC) of large field DWI and bone scintigraphy were 0.936 vs. 0.910, respectively. Totally 68 abnormal foci were identified from large field DWI and/or bone scintigraphy in 44 patients (while 5 patients with bone metastases exceeding 10 foci per patient were excluded), 20 of them were diagnosed as foci of bone metastasis. The diagnosis of bone metastases was made in 23 foci by large field DWI and in 34 by bone scintigraphy. With lesion numbers as study units (n=68), the diagnostic sensitivity of large field DWI and bone scintigraphy were both 90.0% (18/20), and specificity were 89.6% (43/48) vs. 66.7% (32/48), respectively. ROC study showed the area under curve of

Maintaining bone health in prostate cancer throughout the disease continuum.

2010-06-01

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

We performed a meta-analysis to evaluate 18FDG PET/PET-CT for the detection of bone metastases in patients with head and neck cancer. We calculated sensitivities, specificities, likelihood ratios, and constructed summary receiver operating characteristic curves for PET and PET-CT, respectively. We also compared the performance of PET/PET-CT with that of bone scintigraphy by analysing studies that had also used bone scintigraphy on the same patients. Across 9 PET studies (1621 patients) and 10 PET-CT studies (1291 patients), sensitivity and specificity of PET were 0.81 and 0.99, and of PET-CT were 0.89 and 0.99, respectively. In 5 comparative studies (1184 patients), sensitivity and specificity of PET/PET-CT were 0.85 and 0.98, and of bone scintigraphy were 0.55 and 0.98, respectively. 18FDG PET and PET-CT have high sensitivity and accuracy for the detection of bone metastasis in patients with head and neck cancer.

Metastases to cervical lymph node are fairly common in differentiated thyroid cancer. In iodine-refractory disease, the disease may persist in the thyroid bed, cervical lymph nodes, lungs, or the bones commonly. Retropharyngeal lymph nodal involvement in thyroid cancer is unusual and may even be the presenting complaint. We represent a case of iodine-refractory thyroid cancer with retropharyngeal lymph nodal involvement in addition to lung metastases.

Bone metastases are involved in a 65-75% of advanced metastatic breast cancer cases. Tumoral markers (CEA, CA 15.3) are useful in the follow-up and evaluation of response to treatment. Hormonal therapy is the optimal treatment option in low grade metastatic breast cancer due to low toxicity and general long term good response. We present a breast cancer case treated with surgery, chemotherapy and radiotherapy. The patient was asymptomatic during the follow-up and multiple bone metastases were diagnosed as a result of an increased CA 15.3 marker found. Hormone therapy was the recommended initial treatment with good response and tolerance. Bone lesions remained stabilized for 7 years but after treatment suspension new bone lesions appeared. CA 15.3 marker had increased again. Reintroduction of hormonal therapy achieved again the stabilization of the lesions

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

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

Full text: The objective of this study was to compare the levels of CA15-3 and CEA with the bone scan findings in patients with breast cancer. Retrospective analysis of 76 bone scans from 61 patients diagnosed with breast cancer in the last 5 years was performed by two nuclear medicine specialists. All bone scans were performed after surgical treatment of the disease. Patients with loco-regional residual disease or distant metastases in the liver, lung or the brain were excluded from the study. According to the bone scan the patients were divided in 5 groups: normal bone scan (N), equivocal bone scan (E), single metastasis (1MS), three metastases (3MS) and multiple metastases (MMS). Tumor markers were determined within a month before or after the bone scan was performed. Cut-off value for CA 15-3 was 35 U/ml, and for CEA 3 ng/ml. Statistical analysis was performed using descriptive statistic and Kolmogorov-Smirnov test. Bone metastases were revealed in 38% of the patients referred for bone scintigraphy out of which 26% had MMS, 7.8% had single MS and 4% had 3MS. The results of 6.5% of the patients were determined as equivocal. The values of CA15-3 were higher in all patient groups compared with the group that had normal bone scan, but this difference reached statistical significance only in groups with 3MS and MMS (p < 0.01). The values of CEA were significantly higher only in patients with multiple metastases when compared with group N (p < 0.01). Values higher than cut-off value for CA 15-3 was found in 9 patients out of 42 in the group with normal bone scan. The highest value of CA 15-3 in this group was 47 U/ml. Only one patient in this group showed elevated levels for CEA. Three patients in the group with single metastasis had normal CA 15-3, while CEA was elevated only in one patient. All patients in the group with 3MS had elevated levels of CA 15-3 while CEA was in the normal range. All patients with MMS had elevated CA 15-3 values while CEA was elevated in

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

This study aims to explore physician-patient communications about bone metastases and cancer treatment-induced bone loss (CTIBL). The study utilizes online survey of patients with breast cancer, prostate cancer, and multiple myeloma, and the physicians who treat them. Even though 69 and 48 % of patients with nonmetastatic breast and prostate cancer aware of treatment-induced bone loss, only 39 and 23 %, respectively, were concerned about bone loss. Yet, 62 and 71 % of oncologists treating breast and prostate cancer felt that their patients were concerned. Among patients with metastatic breast and prostate cancer, two thirds had not discussed treatment for bone metastases with their doctor; when discussed, 88 and 91 % of discussions were initiated by the doctor, usually prior to initiating treatment. Most myeloma patients (77 %) had discussed treatment options with their physicians; 99 % of hematologists reported discussing treatment of bone disease with patients. Physicians are primary sources of information to patients regarding bone health. There is a gap between what physicians assume their patients know about bone health and the patients' perceptions, presenting a need for systematic awareness and education.

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

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

Eight patients with malignant tumor (3 with gastric cancer, 4 with prostatic cancer, 1 with transitional cell carcinoma), which showed diffusely increased uptake of 99m Tc labelled phosphorous compound in axial skeleton (''Super Bone Scan'') on bone scintigraphy were clinically studied. No relationship with its histological type of the tumor was recognized. All cases revealed extremely high serum ALP concentration, which might reflect increased osteoblastic activity. Furthermore, on bone roentgenograms all cases showed predominantly osteosclerotic change in the metastatic bones, while some did locally osteolytic change. In three cases with gastric cancer, although they had diffuse skeletal metastases, two had no evidence of liver metastases. Thus, it seemed that clinical study of patients with ''Super Bone Scan'' was interesting to evaluate the mechanism of accumulation of 99m Tc labelled phosphorous compound to bone and bone metabolism, and the pathophysiology in the pathway of bone metastases.

Highlights: •DKK1 level was associated with NSCLC bone metastases. •Lung tumor cells derived DKK1 inhibited osteoblast differentiation. •Lung tumor cells derived DKK1 modulates β-catenin and RUNX2. -- Abstract: Wnt/β-catenin signaling and Dickkopf1 (DKK1) play important roles in the progression of lung cancer, which preferably metastasizes to skeleton. But the role of them in bone dissemination is poorly understood. This study aims to define the role of DKK1 in lung cancer bone metastases and investigate the underlying mechanism. Our results demonstrated that DKK1 over-expression was a frequent event in non-small-cell lung cancer (NSCLC) blood samples, and serous DKK1 level was much higher in bone metastatic NSCLC compared to non-bone metastatic NSCLC. We also found that conditioned medium from DKK1 over-expressing lung cancer cells inhibited the differentiation of osteoblast, determined by alkaline phosphatase activity and osteocalcin secretion, whereas the conditioned medium from DKK1 silencing lung cancer cells exhibited the opposite effects. Mechanistically, DKK1 reduced the level of β-catenin and RUNX2, as well as inhibiting the nuclear translocation of β-catenin. Taken together, these results suggested that lung cancer-produced DKK1 may be an important mechanistic link between NSCLC and bone metastases, and targeting DKK1 may be an effective method to treat bone metastase of NSCLC.

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.

The objective of this study was to investigate the incidence of skeletal-related events (SRE) in urological cancer patients with bone metastases in Japan. Five hundred eleven patients with urological cancer and documented bone metastases treated from January 2003 to April 2008 in ten Japanese institutions were included in a retrospective analysis. Type and incidence of SRE (fracture, radiotherapy, spinal cord compression, surgery, hypercalcemia, and bone pain) were determined from patient medical records. The overall incidence of SRE, including 'pain', was 61%. The most common event was radiotherapy for bone metastases, with an incidence of 31%. The overall incidence of events seemed to be similar among Japanese and Western patients with prostate cancer and renal cell carcinoma when comparing data with previously published reports. Nevertheless, a much lower incidence of fracture (19.1%) was observed in Japanese renal cell carcinoma patients. The overall incidence of SRE in Japanese urological cancer patients with bone metastasis was similar to that in Western patients, but the incidence of fracture was lower in Japanese renal cancer patients.

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

The recent development of the technique described, especially in the systematic search for metastases was due to the introduction of stannous diphosphate complexed with sup(99m)Tc well suited to bone scintigraphy. The documents are obtained in two stages. First a whole-body scintigraph is taken by means of an omniview device fitted to a Picker dynacamera, and this scanning phase is followed immediately by static views centred mainly on abnormal or doubtful regions. The results are given for 136 breast cancers and 61 prostate cancers, two cancers particularly liable to affect the bone, and show that scintigraphy offers positive advantages over radiological investigations. These advantages are offset to some extent by the non-specific nature of the hyperfixing regions since different diseases involving changes in the bone structure can give similar images, but for breast and prostate cancers bone scintigraphy presents distinct possibilities in the search for metastases of the skeleton [fr

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.

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.

Bone is the most common site for metastasis in human prostate cancer patients. Skeletal metastases are a significant cause of morbidity and mortality and overall greatly affect the quality of life of prostate cancer patients. Despite advances in our understanding of the biology of primary prostate tumors, our knowledge of how and why secondary tumors derived from prostate cancer cells preferentially localize bone remains limited. The physiochemical properties of bone, and signaling molecules including specific chemokines and their receptors, are distinct in nature and function, yet play intricate and significant roles in prostate cancer bone metastasis. Examining the impact of these facets of bone metastasis in vivo remains a significant challenge, as animal models that mimic the natural history and malignant progression clinical prostate cancer are rare. The goals of this article are to discuss (1) characteristics of bone that most likely render it a favorable environment for prostate tumor cell growth, (2) chemokine signaling that is critical in the recruitment and migration of prostate cancer cells to the bone, and (3) current animal models utilized in studying prostate cancer bone metastasis. Further research is necessary to elucidate the mechanisms underlying the extravasation of disseminated prostate cancer cells into the bone and to provide a better understanding of the basis of cancer cell survival within the bone microenvironment. The development of animal models that recapitulate more closely the human clinical scenario of prostate cancer will greatly benefit the generation of better therapies

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

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

In this paper we report on a successful management of multiple bone metastases from differentiated thyroid cancer. In 2007, a 75-year-old female patient, previously referred for thyroidectomy for multinodular goiter, underwent surgical removal of a lumbar mass with histological findings of metastasis from well differentiated thyroid cancer. After surgery, serum thyroglobulin (sTg) was 204.4 ng/mL. A diagnostic/dosimetric (123)I WBS was performed, following stimulation by rTSH. Serial WBSs were acquired, along with SPECT/CT and bone scan for localization of lesions. sTg raised to 3.810 ng/mL, and (123)I WBS showed thyroid remnants and numerous areas with high iodine-uptake corresponding to skeletal sites, the two largest loading on the skull, with osteolytic pattern. Calculated radiation absorbed dose for skull lesions, determined by mean of MIRD methodology, was 63.5 mGy/MBq. The patient underwent surgical removal of the two major skull lesions. Successively, 100 mCi (131)I was administered after stimulation by rTSH, with stimulated sTg 297 ng/mL. After 8 months, diagnostic WBS was negative both for remnants and metastases and rTSH-stimulated Tg was 0.6 ng/mL. To date, the patient has maintained sTg values <1 ng/mL during L-T4 suppressive therapy and after rTSH stimulations. In this unusual case of extensive bone cancerous involvement with high iodine avidity, a multidisciplinary approach based on surgery and dosimetry-guided radiometabolic therapy allowed to accurately assess the patient, execute a small number of treatments and achieve a complete remission of the disease in a very short time, with no additive morbidity.

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 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, γ-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.

Purpose: prostate cancer continues to be the third leading cancer-related mortality of western men. Early diagnosis of bone metastasis is important for the therapy regime and for assessing the prognosis. The standard method is bone scintigraphy. Whole-body MRI proved to be more sensitive for early detection of skeletal metastasis. However, studies of homogenous tumor entities are not available. The aim of the study was to compare bone scintigraphy and whole-body MRI regarding the detection of bone metastasis of prostate cancer. Materials and methods: 14 patients with histologically confirmed prostate cancer and a bone scintigraphy as well as whole-body MRI within one month were included. The mean age was 68 years. Scintigraphy was performed using the planar whole-body technique (ventral and dorsal projections). Suspect areas were enlarged. Whole-body MRI was conducted using native T1w and STIR sequences in the coronary plane of the whole body, sagittal imaging of spine and breath-hold STIR and T1w-Flash-2D sequences of ribs and chest. Bone scintigraphy and whole-body MRI were evaluated retrospectively by experienced radiologists in a consensus reading on a lesion-based level. Results: whole-body MRI detected significantly more bone metastasis (p = 0.024). 96.4% of the demonstrated skeletal metastases in bone scintigraphy were founded in whole-body MRI while only 58.6% of the depicted metastases in MRI were able to be located in scintigraphy. There was no significant difference regarding bone metastasis greater than one centimeter (p = 0.082) in contrast to metastasis less than one centimeter (p = 0.035). Small osteoblastic metastases showed a considerably higher contrast in T1w sequences than in STIR imaging. Further advantages of whole-body MRI were additional information about extra-osseous tumor infiltration and their complications, for example stenosis of spinal canal or vertebral body fractures, found in 42.9% of patients.

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

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

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

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

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

One of the main limitations, when studying cancer-bone metastasis, is the complex nature of the native bone environment and the lack of reliable, simple, inexpensive models that closely mimic the biological processes occurring in patients and allowing the correct translation of results. To enhance the understanding of the mechanisms underlying human bone metastases and in order to find new therapies, we developed an in vitro three-dimensional (3D) cancer-bone metastasis model by culturing human breast or prostate cancer cells with human bone tissue isolated from female and male patients, respectively. Bone tissue discarded from total hip replacement surgery was cultured in a rolling apparatus system in a normoxic or hypoxic environment. Gene expression profile, protein levels, histological, immunohistochemical and four-dimensional (4D) micro-CT analyses showed a noticeable specificity of breast and prostate cancer cells for bone colonization and ingrowth, thus highlighting the species-specific and sex-specific osteotropism and the need to widen the current knowledge on cancer-bone metastasis spread in human bone tissues. The results of this study support the application of this model in preclinical studies on bone metastases and also follow the 3R principles, the guiding principles, aimed at replacing/reducing/refining (3R) animal use and their suffering for scientific purposes.

In January 2014 the Comision Federal para la Proteccion contra Riesgos Sanitarios of the Ministry of Health in Mexico, authorize the use of 223 RaCl 2 as the first radiopharmaceutical emitter α for therapeutic purposes in cases of bone metastases resulting from prostate cancer resistant to castration. The paper analyzes the main variables that affect the metrological traceability using activity meters to evaluate the gamma activity of 223 RaCl 2 in hospitals, because it has a chain of complex decay with alpha, beta and gamma emitters, so was important to verify if a gamma activity measurement for a multiple emitter is reliable to determine the total alpha absorbed dose to bone in a patient.

Highlights: •PCDH7 is overexpression in high bone metastatic MDA-MB-231 cells. •PCDH7 is up-regulation in bone metastatic breast cancer tissues. •Suppression of PCDH7 inhibits cell proliferation, migration, and invasion in vitro. •PCDH7 induces breast cancer bone metastasis in vivo. -- Abstract: Breast cancer had a propensity to metastasize to bone, resulting in serious skeletal complications associated with poor outcome. Previous study showed that Protocadherin-7 (PCDH7) play an important role in brain metastatic breast cancer, however, the role of PCDH7 in bone metastatic breast cancer has never been explored. In the present study, we found that PCDH7 expression was up-regulation in bone metastatic breast cancer tissues by real-time PCR and immunohistochemistry assays. Furthermore, suppression of PCDH7 inhibits breast cancer cell proliferation, migration, and invasion in vitro by MTT, scratch, and transwell assays. Most importantly, overexpression of PCDH7 promotes breast cancer cell proliferation and invasion in vitro, and formation of bone metastasis in vivo. These data provide an important insight into the role of PCDH7 in bone metastasis of breast cancer.

We used a combination of bone and bone-marrow scintigraphy to study 25 patients with prostatic cancer. Of the 18 cases whose sup(99m)Tc-methylene diphosphonate (MDP) bone scans showed hot spots in the lower lumbar region of the spine and/or the pelvic bone, 8 had normal bone-marrow scintigrams. These 8 patients, were subsequently shown to have senile, degenerative changes of the spine. On the other hand, in 9 of the 10 patients whose bone-marrow scintigrams showed accumulation defects, follow-up study and characteristic X-ray findings confirmed the presence of metastases. In all 6 cases with extensive bone metastases shown by sup(99m)Tc-MDP bone scintigraphy, sup(99m)Tc-sulphur-colloid bone-marrow scintigraphy showed multiple accumulation defects. In conclusion, bone-marrow scintigraphy was found to be useful in distinguishing metastatic lesions from benign degenerative changes in the cases with suspected bone involvement, as well as in evaluating equivocal lesions in the pelvis.

Most cases of disseminated carcinomatosis of the bone marrow (DCBM) arise from gastric cancer. DCBM from pancreatic cancer is very rare. We herein present a case of DCBM from pancreatic cancer. A 57-year-old man was referred to our hospital for severe lumbago. Laboratory data indicated that he suffered from disseminated intravascular coagulation (DIC). Non-contrast abdominal computed tomography (CT) revealed multiple bone masses but no other abnormal findings. Left iliac bone marrow biopsy revealed poorly differentiated adenocarcinoma cells. Positron emission tomography (PET)-CT showed diffuse abnormal uptake in the bones and tail of the pancreas. Contrast whole-body CT showed a tumor measuring approximately 28 mm in diameter with poor enhancement in the tail of the pancreas. The patient’s final diagnosis was pancreatic cancer located in the tail of the pancreas with diffuse bone metastases and DIC. His DCBM was thus believed to originate from the pancreatic cancer. He succumbed to the disease approximately 2 months after admission to our hospital. We herein describe a case of pancreatic cancer located in the tail of the pancreas with diffuse bone metastases and DIC, which, in our case, was DCBM. Therefore, in cases of DCBM with an unknown primary tumor, pancreatic cancer should be considered during differential diagnosis

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

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

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.

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.)

Radionuclide therapy is widely used as an effective modality in the management of bone pain. The main indication for this treatment is symptomatic bone metastases, confirmed by bone scintigraphy. We present a case of small cell lung cancer (SCLC) stage T 4 N 2 M 1b , with a good metabolic response to systemic therapy and radiotherapy of the primary tumor and locoregional disease, which became metabolically less active and remarkably smaller in size (reduction to 1/6 of the original volume). In spite of the good overall response, the patient developed a syndrome with severe bone pain and had progression in the bone marrow metastases, confirmed by 18 F-FDG PET/CT. The patient received 153 Sm-EDTMP treatment with a good clinical response. However, in the whole body bone scan with the therapeutic dose, there was no visual evidence of bone metastasis. Retrospectively, by drawing the region of interest, it was possible to identify one metastatic site. The possible mechanisms of the efficacy of this treatment modality, in this specific setting, are also discussed

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

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.

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

Objective. To characterise the uptake of 18 F in skeletal metastases from breast cancer using positron emission tomography (PET) and to relate these findings to the appearance on CT. Patients and design. PET with 18 F and CT were performed in five patients with multiple skeletal metastases from breast cancer. The CT characteristics were analysed in areas with high uptake on the PET study. Dynamic PET imaging of the skeletal kinetics of the 18 F-fluoride ion were included. Results. The areas of abnormal high accumulation of 18 F correlated well with the pathological appearance on CT. Lytic as well as sclerotic lesions had markedly higher uptake than normal bone, with a 5-10 times higher transport rate constant for trapping of the tracer in the metastatic lesions than in normal bone. Conclusion. PET with 18 F-fluoride demonstrates very high uptake in lytic and sclerotic breast cancer metastases. (orig.)

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

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.

Hyperfunctioning distant metastasis (HFDM) from differentiated thyroid cancer (DTC) is a rare entity. This study aimed to assess the outcomes of DTC patients presenting with HFDM after total thyroidectomy and radioactive iodine therapy. A total of 5367 DTC patients treated with (131)I after total thyroidectomy were analyzed retrospectively from January 1991 to June 2013. Therapeutic efficacy was evaluated based on changes in serum thyroglobulin (Tg) and anatomical imaging changes in metastatic lesions. The relationships between survival time and several variables were assessed by univariate and multivariate analyses using the Kaplan-Meier method and Cox's proportional hazards model respectively. Thirty-eight patients with HFDM from DTC were diagnosed, including four with hyperthyroidism, four with subclinical hyperthyroidism, and three with subclinical hypothyroidism. The remaining 27 were euthyroid. Of 25 patients with lung metastases, 84% (21/25) showed disappearance or shrinkage of lung nodules; of 24 patients with bone metastases, 66.67% (16/24) exhibited no obvious imaging changes in metastatic bone lesions after (131)I therapy. Serum Tg decreased significantly in 81.58% (31/38) and increased in 18.42% (7/38) after (131)I therapy. The 10-year survival rate of DTC patients with HFDM was 65.79% (25/38). Multivariate analyses identified age at occurrence of distant metastases (thyroid cancer (PTC; p=0.032, NA, and 0.043) as independent predictors of survival. The response of hyperfunctioning lung metastases to (131)I treatment was better than that of non-hyperfunctioning lung metastases in DTC, while hyperfunctioning bone metastases responded similarly compared to non-hyperfunctioning bone metastases. Patients younger than 45 years at occurrence of distant metastases, those with only lung metastases, and patients with PTC had better prognoses.

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

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.

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

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

Incidence and sites of distant metastases from head and neck cancer.

The incidence of distant metastases in head and neck squamous cell carcinoma (SCC) is relatively small in comparison to other malignancies. Distant metastases adversely impact survival and may significantly affect treatment planning. The incidence of distant metastases is influenced by location of the primary tumor, initial T and N stage of the neoplasm, and the presence or absence of regional control above the clavicle. Patients with advanced nodal disease have a high incidence of distant metastases, particularly in the presence of jugular vein invasion or extensive soft tissue disease in the neck. Primary tumors of advanced T stages in the hypopharynx, oropharynx and oral cavity are associated with the highest incidence of distant metastases. Pulmonary metastases are the most frequent in SCC, accounting for 66% of distant metastases. It may be difficult to distinguish pulmonary metastasis from a new primary tumor, particularly if solitary. Other metastatic sites include bone (22%), liver (10%), skin, mediastinum and bone marrow. An important question remains as to how intensely pre- and postoperative screening for distant metastases should be performed. Preoperative chest X-ray is warranted in all cases. If the primary tumor and nodal status place the patient at high risk for pulmonary metastasis, then preoperative computed tomography scan of the chest should be done. Screening for distant metastases at other sites is usually not indicated in SCC of the upper aerodigestive tract. Postoperatively, annual X-rays of the chest are usually sufficient, but in high-risk situations a chest X-ray performed every 3-6 months may be beneficial. Certain histologic types of primary tumor have greater or lesser propensity to metastasize distantly, and have a different natural history. Adenoid cystic carcinoma metastasizes frequently, even in the absence of extensive local or regional disease. Basaloid squamous cell carcinoma and neuroendocrine carcinomas also metastasize widely

Distant metastases are the most common and lethal type of breast cancer relapse. The authors examined whether older African American breast cancer survivors were more likely to develop metastases compared with older white women. They also examined the extent to which 6 pathways explained racial disparities in the development of metastases. The authors used 1992-1999 Surveillance, Epidemiology, and End Results (SEER) data with 1991-1999 Medicare data. They used Medicare's International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify metastases of respiratory and digestive systems, brain, bone, or other unspecified sites. The 6 pathways consisted of patient characteristics, tumor characteristics, type of treatment received, access to medical care, surveillance mammography use, and area-level characteristics (poverty rate and percentage African American) and were obtained from the SEER or Medicare data. Of the 35,937 women, 10.5% developed metastases. In univariate analysis, African American women were 1.61 times (95% confidence interval [CI], 1.54-1.83) more likely to develop metastasis than white women. In multivariate analysis, tumor grade, stage at diagnosis, and census-tract percentage African American explained why African American women were more likely to develop metastases than white women (hazard ratio, 0.84; 95% CI, 0.68-1.03). Interventions to reduce late-stage breast cancer among African Americans also may reduce racial disparities in subsequent increased risk of developing metastasis. African Americans diagnosed with high-grade breast cancer could be targeted to reduce their risk of metastasis. Future studies should identify specific reasons why the racial distribution in census tracts was associated with racial disparities in the risk of breast cancer metastases.

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 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 2 solution (containing 1.4 mg Ca and 5nCi 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 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 41 Ca/Ca in longitudinal urinary samples can sensitively reveal the skeletal perturbations caused by bone metastasis of rats, suggests that 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.

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

Contribution of scintigraphy in the search for bone metastases

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

Radiation therapy for metastatic lesions from breast cancer. Breast cancer metastasis to bone

International Nuclear Information System (INIS)

Hayashi, Shinya; Hoshi, Hiroaki

2000-01-01

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

Eighty seven patiensts with mammary carcinoma and positive skeletal scintigram were submitted to a roentgenologic study to determine the accuracy of the scintigram findings. The skeletal roentgenograms performed immediately after the scintigram confirmed osseous metastases in 60.9% of the cases, after 3 months in 76.5%, after 6 months in 81.5% and, finally, after 12 months the metastases were radiologically confirmed in 89.3% of the cases. The reasons of no confirmation of metastases in 10.7% of the cases are discussed. (Author) [pt

Strontium nitrate Sr-87m bone scans were made preoperatively in a group of women with suspected breast cancer, 35 of whom subsequently underwent radical mastectomy. In 3 of the 35 (9 percent), the scans were abnormal despite the absence of clinical or roentgenographic evidence of metastatic disease. All three patients had extensive axillary lymph node involvement by tumor, and went on to have additional bone metastases, from which one died. Roentgenograms failed to detect the metastases in all three. Occult bone metastases account in part for the failure of radical mastectomy to cure some patients with breast cancer. It is recommended that all candidates for radical mastectomy have a preoperative bone scan. (U.S.)

1999-01-01

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

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

Full Text Available Osteoporosis is one of the most significant bone complications of cancer. About 1.5 million cancer patients worldwide have bone metastases. Patients with myeloma, breast cancer, prostate, thyroid, bladder and lung have very high risk of development of bone lesions and related complications. Currently, osteodensitometry is the gold standard for the diagnosis of osteoporosis. In recent years we frequently use the innovative imaging techniques for bone metastases, such as CT, MRI, PET/CT. Unfortunately, the diagnostic value of these methods is that it is not always possible to identify abnormalities of bone metabolism in cancer, especially in the early stages. This review shows the world experience of usage of biochemical markers of bone resorption (calcium, hydroxyproline, NTX, CTX, PYD, DPD, TRAP-5b, bone sialoprotein - BSP and markers of bone synthesis (osteocalcin, CSF, ACF, Karlovy vary IFF, their advantages and disadvantages. The level of these markers is increased in most patients with osteoporosis and bone metastases, it is suggesting a potential role in early diagnosis of bone metastases.

What Is Breast in the Bone?

The normal developmental program that prolactin generates in the mammary gland is usurped in the cancerous process and can be used out of its normal cellular context at a site of secondary metastasis. Prolactin is a pleiotropic peptide hormone and cytokine that is secreted from the pituitary gland, as well as from normal and cancerous breast cells. Experimental and epidemiologic data suggest that prolactin is associated with mammary gland development, and also the increased risk of breast tumors and metastatic disease in postmenopausal women. Breast cancer spreads to the bone in approximately 70% of cases with advanced breast cancer. Despite treatment, new bone metastases will still occur in 30%-50% of patients. Only 20% of patients with bone metastases survive five years after the diagnosis of bone metastasis. The breast cancer cells in the bone microenvironment release soluble factors that engage osteoclasts and/or osteoblasts and result in bone breakdown. The breakdown of the bone matrix, in turn, enhances the proliferation of the cancer cells, creating a vicious cycle. Recently, it was shown that prolactin accelerated the breast cancer cell-mediated osteoclast differentiation and bone breakdown by the regulation of breast cancer-secreted proteins. Interestingly, prolactin has the potential to affect multiple proteins that are involved in both breast development and likely bone metastasis, as well. Prolactin has normal bone homeostatic roles and, combined with the natural "recycling" of proteins in different tissues that can be used for breast development and function, or in bone function, increases the impact of prolactin signaling in breast cancer bone metastases. Thus, this review will focus on the role of prolactin in breast development, bone homeostasis and in breast cancer to bone metastases, covering the molecular aspects of the vicious cycle.

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

According to several guidelines, it is acceptable to spare a bone scan in the patients who are newly diagnosed with low-risk prostate cancer. Our aim is to clarify a suitable group whereby a bone scan could be spared at the initial staging of prostate cancer. Consecutive 857 patients who were newly diagnosed from 2004 through 2009 and received bone scans using technetium 99m methylene diphosphonate at the initial staging were enrolled. The proportion of positive bone metastases by age distribution, prostate-specific antigen level at diagnosis, Gleason score and clinical T stage were evaluated. Univariate and multivariate logistic regression analyses were performed to identify the predictors of positive bone metastases. Of all 857 patients, 40 patients (4.7%) showed bone metastases. Patients with higher age, prostate-specific antigen level, clinical stage and Gleason score showed significantly higher rate of bone metastases (P 50 ng/ml and the Gleason score ≥4+3 were independent predictors of bone metastases. The incidences of bone metastases in patients with a prostate-specific antigen level of ≤20 ng/ml and Gleason score of ≤6 were reasonably low. Collectively, a bone scan is not necessary as a routine examination for these patients at their initial staging of prostate cancer. (author)

Neurologic disturbances in case of breast cancer disseminated into cranial bones

Tarasyuk, S.V.; Letyagin, V.P.

1986-01-01

The paper presents data on 52 cases of breast cancer disseminated into cranial vault bones (2 into the orbit). Metastases into the brain (2) and meninges (6) were detected in 17 cases with the aid of computerized tomography of the brain and examination of cerebrospinal fluid. The latter cases were not included into the study group. Metastases into cranial bones were identified by craniography and scanning of the skeleton. Half the patients (18 out of 35) revealed the following neurologic syndromes which were determined by the site of metastases into cranial vault bones and tumour growth pattern (into cranial cavity or soft tissues of the head): lesions in ramus primus nervi trigemini, greater occipital nerve, migraine, pseudotumorous and pseudoencephalitic syndromes. Cases of such neurologic disorders require an all-round examination including ophthalmooscopy, EEG, computerized tomography of the brain, craniography and scanning of the skeleton

Full Text Available A characteristic feature of many cancer types is their ability to metastasise to the skeleton. Bone is the most common site of metastatic invasion, after hematogenous spreading of breast cancer. Early detection of bone metastases is mandatory in the evaluation and management of these patients. Bone scintigraphy is commonly performed in detection and evaluation bone metastases. Tumor markers are present in healthy individuals as well as in patients with malignant diseases but in different concentration. Aim of study was to correlate serum levels of tumor marker Ca (15-3, CEA and presence of bone metastases detected by bone scintigraphy. Study included 25 patients with breast cancer, previously surgically treated. All patients underwent whole body scintigraphy. Ca (15-3 and CEA was measured by radioimmunoassay. Presence, number of bone metastases were correlated with Ca (15-3 and CEA levels. Median age of patients included in study was 50 varying from 30 to 67. Bone scintigraphy revealed bone metastases in 16 (64% patients. A weak correlation was found between number of metastases and level of Ca (15-3 (r=0.139, p=0.254. Significant differences in Ca (15-3 level was found in patient with metastases compared to patients without metastases (chi square 0, p=1.0. Good correlation was found between number of metastases and serum level of CEA. Correlation between level of two tumor markers Ca (15-3 and CEA was a weak (r = 0.096 , p=0.323. Bone scintigraphy is a sensitive diagnostic toll for detecting breast cancer metastases to bone. Serum levels of tumor markes in isolation can not give complete accuracy about bone metastases.

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

Bone metastases are common in patients with advanced solid tumors, and many individuals experience debilitating skeletal-related events (SREs; e.g. pathologic fracture, hypercalcemia, radiotherapy or surgery to bone, and spinal cord compression). These events substantially affect disease outcomes, including survival and quality of life, and healthcare systems. Plain radiography is the most widely used imaging modality for the detection of bone metastases; skeletal scintigraphy, computed tomography, positron emission tomography and magnetic resonance imaging offer greater sensitivity but their use in routine practice is restricted by high costs and limited availability. Biomarkers of bone turnover may also have a role in the early detection of bone metastases and can provide valuable prognostic information on disease progression. SREs can be delayed or prevented using agents such as the receptor activator of nuclear factor kappa B ligand (RANKL) inhibitor, denosumab, and bisphosphonates. Painful bone metastases can be treated with radiofrequency ablation, radiotherapy, or radionuclides such as radium-223 dichloride, which has been shown to delay the onset of SREs in men with castration-resistant prostate cancer. Close monitoring of bone health in patients with advanced cancer may lead to early identification of individuals with bone metastases who could benefit from early intervention to prevent SREs. This review examines current guideline recommendations for assessing and monitoring bone health in patients with advanced cancer, use of biomarkers and treatment of patients with bone metastases. The emerging evidence for the potential survival benefit conferred by early intervention with denosumab and bisphosphonates is also discussed, together with best practice recommendations.

2000-01-01

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

Objective: To evaluate positron emission tomography/computed tomography (PET/CT) and conventional imaging tests for the detection of distant metastases in patients with locally advanced breast cancer. Materials and Methods: We included 81 patients with breast cancer who had undergone {sup 18}-fluorodeoxyglucose (FDG) PET/CT before treatment. Conventional imaging included the following: bone scintigraphy; chest X-ray (in 14.5%) or CT (in 85.5%); and abdominal ultrasound (in 10.8%), CT (in 87.8%), or magnetic resonance imaging (in 1.4%). Histopathology and clinical/imaging follow-up served as reference. Results: Distant metastases were observed in nine patients (11.1%). On patient-based analysis, conventional imaging identified distant metastases in all 9 patients. In one patient, the initial {sup 18}F-FDG PET/CT failed to demonstrate bone metastases that was evident on bone scintigraphy. In two patients, the CT scan failed to show extra-axillary lymph node metastases that were identified on {sup 18}F-FDG PET/CT. There was no significant difference between {sup 18}F-FDG PET/CT and conventional imaging in terms of their sensitivity for the detection of distant metastases in patients with locally advanced breast cancer. Conclusion: This study showed that {sup 18}F-FDG PET/CT and conventional imaging with CT scans had similar sensitivity for the diagnosis of distant metastases in patients with locally advanced breast cancer. {sup 18}F-FDG PET/CT can add information about extra-axillary lymph node involvements.

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

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

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

Detection of bone marrow involvement in patients with cancer

Federico, M.; Silingardi, V.; Wright, R.M.

Current methods for the study of bone marrow to evaluate possible primary or metastatic cancers are reviewed. Bone marrow biopsy, radionuclide scan, computed tomography and magnetic resonance imaging (MRI) are analyzed with regard to their clinical usefulness at the time of diagnosis and during the course of the disease. Bone marrow biopsy is still the examination of choice not only in hematologic malignancies but also for tumors that metastasize into the marrow. Radionuclide scans are indicated for screening for skeletal metastases, except for those from thyroid carcinoma and multiple myeloma. Computed tomography is useful for cortical bone evaluation. MRI shows a high sensitivity in finding occult sites of disease in the marrow but its use has been restricted by high cost and limited availability. However, the future of MRI in bone marrow evaluation seems assured. MRI is alredy the method of choice for diagnosis of multiple myeloma, when radiography is negative, and for quantitative evaluation of lymphoma when a crucial therapeutic decision (i.e. bone marrow transplantation) must be made. Finally, methods are being developed that will enhance the sensitivity and specificity of MRI studies of bone marrow

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

Guerra Liberal, Francisco D. C.; Tavares, Adriana Alexandre S.; Tavares, João Manuel R. S.

2014-01-01

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

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.

Colon cancer has been one of the major tumors in the world, both men and women; and it is constituted the third most commonly diagnosed tumor, with approximately 1.2 million of new cases per year. This cancer type is considered of great importance in Costa Rica and has occupied the fifth place. Age is the main risk factor, followed by environmental, diabetic and genetic factors. An IV colon cancer has been manifested with any T, with any N and metastases. Metastases from colon cancer to liver can be classified according to whether have been synchronous (20 to 25%) or metachronous (15 to 29%). In turn, they can be synchronous, resectable or unresectable or mechanical resectable or unresectable. The liver has been the most common site of metastases, and the status of this organ has been an important determinant of overall survival in patients with advanced disease. Half of the patients developed metastases during the course of the disease. Metastases has represented the leading cause of death from this tumor. With the advent of new surgical techniques, new anesthetic care, new chemotherapeutic and molecular agents, together with new radiofrequency modalities and ablative treatment, the approach of metastases from colon cancer to the liver has been shown to be decisive in the prolongation of survival of the patient, who in the past was considered a terminal patient [es

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.

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

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

Disseminated cancer cells may initially require local nutrients and growth factors to thrive and survive in bone marrow. However, data on the influence of bone marrow derived cells (BMDC, also called bone stromal cells in some publications) on lung cancer cells is largely unexplored. This study explored the mechanism of how bone stromal factors contribute to the bone tropism in lung cancer. The difference among lung cancer cell lines in their abilities to metastasize to bone was found using the SCID animal model. Supernatant of bone marrow aspiration (BM) and condition medium from human bone stromal cells (BSC) were used to study the activity of bone stromal factors. We found bone stromal factors significantly increased the proliferation, invasion, adhesion and expression of angiogenosis-related factors, and inhibited the apoptosis for high bone metastasis H460 lung cancer cells. These biologic effects were not seen in SPC-A1 or A549 cells, which are low bone metastasis lung cancer cells. Adhesion of H460 cells to surface coated with bone stromal cells can activate some signal transduction pathways, and alter the expression of adhesion associated factors, including integrin β 3 and ADAMTS-1, two potential targets related with bone metastasis. We concluded that bone marrow derived cells had a profound effect on biological behavior of lung cancers, therefore favoring the growth of lung cancer cells in bone.

Chemokines and their receptors have key roles in cancer progression. The present study investigated chemokine activity in the prostate cancer bone metastasis microenvironment. Growth and migration of human prostate cancer cells were assayed in cocultures with bone stromal cells. The migration of LNCaP cells significantly increased when co-cultured with bone stromal cells isolated from prostate cancer bone metastases. Cytokine array analysis of conditioned medium from bone stromal cell cultures identified CCL5 as a concentration-dependent promoter of LNCaP cell migration. The migration of LNCaP cells was suppressed when C-C motif ligand 5 (CCL5) neutralizing antibody was added to cocultures with bone stromal cells. Knockdown of androgen receptor with small interfering RNA increased the migration of LNCaP cells compared with control cells, and CCL5 did not promote the migration of androgen receptor knockdown LNCaP. Elevated CCL5 secretion in bone stromal cells from metastatic lesions induced prostate cancer cell migration by a mechanism consistent with CCL5 activity upstream of androgen receptor signaling. © 2017 The Authors.

Where Do Bone-Targeted Agents RANK in Breast Cancer Treatment?

Directory of Open Access Journals (Sweden)

Roger von Moos

Full Text Available Breast cancer cells preferentially metastasise to the skeleton, owing, in part, to the fertile environment provided by bone. Increased bone turnover releases growth factors that promote tumour cell growth. In turn, tumour cells release factors that stimulate further bone turnover, resulting in a vicious cycle of metastasis growth and bone destruction. The RANK-RANK ligand (RANKL pathway plays a key role in this cycle, and inhibition of RANKL using the fully-human monoclonal antibody denosumab, has demonstrated efficacy in delaying skeletal complications associated with bone metastases in three phase 3 trials. Preclinical studies suggest that the RANKL pathway also plays a role in breast cancer tumourigenesis and migration to bone. In a subgroup analysis of the negative Adjuvant Zoledronic Acid to Reduce Recurrence (AZURE trial, the bisphosphonate zoledronic acid showed potential for improving survival in patients who were postmenopausal; however, a prospective study in this patient population is required to validate this observation. Ongoing trials are examining whether adjuvant blockade of the RANKL pathway using denosumab can prevent disease recurrence in patients with high-risk breast cancer. These are building on analogous studies that have shown that denosumab improves bone metastasis-free survival in prostate cancer and suggested that it confers an overall survival benefit in non-small-cell lung cancer.

Skeleton is one of the most common metastatic organs for breast cancer, which has a better prognosis than visceral metastases. Bone-only metastasis was defined"non-measurable" in the RECIST (Response Evaluation Criteria in Solid Tumors) criteria, and was excluded by clinical trials. However, patients with bone-only metastasis are also in need of effective treatment to prolong survival. Endocrine therapy is the most important treatment for bone metastatic patients. Tumor response of bone metastases can be determined objectively by bone-window CT. Effective treatment should be continued if the symptoms are relieved or osteogenesis is observed. Osteoblastic change in bone-window CT is a sign of improvement after treatment. Endocrine therapy is proper for ER-positive patients. The patients with initial osteoblastic metastasis should not be treated with salvage chemotherapy or anti-HER2 treatment, only if osteolytic metastasis or visceral metastasis is observed. Bishosphonates are just auxiliary drugs in bone metastasis, which should not be abused.

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

Breast cancer is one of the most common cancers in women in the world. Although breast cancer is well treatable at the early stage, patients with distant metastases show a poor prognosis. Data from recent studies using transplantation models indicate that Mint3/APBA3 might promote breast cancer malignancy. However, whether Mint3 indeed contributes to tumor development, progression, or metastasis in vivo remains unclear. To address this, here we examined whether Mint3 depletion affects tumor malignancy in MMTV-PyMT breast cancer model mice. In MMTV-PyMT mice, Mint3 depletion did not affect tumor onset and tumor growth, but attenuated lung metastases. Experimental lung metastasis of breast cancer Met-1 cells derived from MMTV-PyMT mice also decreased in Mint3-depleted mice, indicating that host Mint3 expression affected lung metastasis of MMTV-PyMT-derived breast cancer cells. Further bone marrow transplant experiments revealed that Mint3 in bone marrow-derived cells promoted lung metastasis in MMTV-PyMT mice. Thus, targeting Mint3 in bone marrow-derived cells might be a good strategy for preventing metastasis and improving the prognosis of breast cancer patients. Copyright © 2017 Elsevier Inc.

Stimulation of host bone marrow stromal cells by sympathetic nerves promotes breast cancer bone metastasis in mice.

Full Text Available Bone and lung metastases are responsible for the majority of deaths in patients with breast cancer. Following treatment of the primary cancer, emotional and psychosocial factors within this population precipitate time to recurrence and death, however the underlying mechanism(s remain unclear. Using a mouse model of bone metastasis, we provide experimental evidence that activation of the sympathetic nervous system, which is one of many pathophysiological consequences of severe stress and depression, promotes MDA-231 breast cancer cell colonization of bone via a neurohormonal effect on the host bone marrow stroma. We demonstrate that induction of RANKL expression in bone marrow osteoblasts, following β2AR stimulation, increases the migration of metastatic MDA-231 cells in vitro, independently of SDF1-CXCR4 signaling. We also show that the stimulatory effect of endogenous (chronic stress or pharmacologic sympathetic activation on breast cancer bone metastasis in vivo can be blocked with the β-blocker propranolol, and by knockdown of RANK expression in MDA-231 cells. These findings indicate that RANKL promotes breast cancer cell metastasis to bone via its pro-migratory effect on breast cancer cells, independently of its effect on bone turnover. The emerging clinical implication, supported by recent epidemiological studies, is that βAR-blockers and drugs interfering with RANKL signaling, such as Denosumab, could increase patient survival if used as adjuvant therapy to inhibit both the early colonization of bone by metastatic breast cancer cells and the initiation of the "vicious cycle" of bone destruction induced by these cells.

Multiple Cutaneous Metastases as Initial Presentation in Advanced Colon Cancer

Directory of Open Access Journals (Sweden)

Sudheer Nambiar

2018-01-01

Full Text Available Skin metastases from advanced colorectal cancer are relatively rare and occur most often when the cancer is advanced, following the spread to other organs. Cutaneous metastases occur in about 3% of advanced colorectal cancers. We present an extremely rare case of a 68-year-old woman with advanced ascending colon adenocarcinoma that presented with multiple rapidly progressing painless cutaneous metastatic lesions with no other distant metastases. Of all the tumors, breast cancer most commonly spreads as cutaneous metastasis is followed by lung, colorectal, renal, ovarian, and bladder cancers. Cutaneous metastases can present in a variety of clinical manifestations, such as a rapidly growing painless dermal or subcutaneous nodule with intact overlying epidermis or as ulcers. In cases where the cutaneous deposit is isolated, as in visceral metastasis, there is a role for radical management such as wide local excision and reconstruction. In our patient, since she had multiple cutaneous metastases she began treatment with palliative systemic combination chemotherapy.

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

1985-01-01

A combination study of bone and bone marrow scintigraphy was performed on 25 pts with prostatic cancer, and, in order to study the usefulness in the diagnosis of bone metastasis, the findings of 2 scintigraphies were compared with those of skeletal roentgenography. Out of the 18 cases with the hot spots of sup(99m)Tc-MDP in the lower lumbar spine or/and the pelvic bone, 8 showed normal bone marrow scintigrams which were eventually proved to have degenerative changes of the spine accompanied by aging. On the other hand, nine cases of the ten, who had accumulation defects on the bone marrow scintigrams were finally proved having bone metastasis. All six cases with extensive bone metastases shown by bone scintigraphy with sup(99m)Tc-MDP, demonstrated multiple accumulation defects on bone marrow scintigraphy with sup(99m)Tc-sulfur colloid. In conclusion, bone marrow scintigraphy was thought to be helpful in distinguishing the metastatic lesions from the benign spinal degenerative changes in the cases with suspicions bone involvement and in evaluating equivocal lesions in the pelvis. Therefore, it was shown that, in the detection and diagnosis of bone metastasis from prostatic cancer, bone scintigraphy alone was insufficient, and that combination with bone marrow scintigraphy was found to be useful.

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

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

Palliative radiotherapy for painful bone metastases, single versus multiple fraction treatment: a literature review

International Nuclear Information System (INIS)

McKee, L.

2005-01-01

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

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.

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.

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

The purpose of this study 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

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

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.

Radiological diagnosis of skeletal metastases

International Nuclear Information System (INIS)

Soederlund, V.

1996-01-01

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

For decades, planar bone scintigraphy has been the standard practice for detection of bone metastases in prostate cancer and has been endorsed by recent oncology/urology guidelines. It is a sensitive method with modest specificity. (18)F-fluoride positron emission tomography/computed tomography has shown improved sensitivity and specificity over bone scintigraphy, but because of methodological issues such as retrospective design and verification bias, the existing level of evidence with (18)F-fluoride positron emission tomography/computed tomography is limited. The primary objective is to compare the diagnostic properties of (18)F-fluoride positron emission tomography/computed tomography versus bone scintigraphy on an individual patient basis. One hundred forty consecutive, high-risk prostate cancer patients will be recruited from several hospitals in Denmark. Sample size was calculated using Hayen's method for diagnostic comparative studies. This study will be conducted in accordance with recommendations of standards for reporting diagnostic accuracy studies. Eligibility criteria comprise the following: 1) biopsy-proven prostate cancer, 2) PSA ≥ 50 ng/ml (equals a prevalence of bone metastasis of ≈ 50% in the study population on bone scintigraphy), 3) patients must be eligible for androgen deprivation therapy, 4) no current or prior cancer (within the past 5 years), 5) ability to comply with imaging procedures, and 6) patients must not receive any investigational drugs. Planar bone scintigraphy and (18)F-fluoride positron emission tomography/computed tomography will be performed within a window of 14 days at baseline. All scans will be repeated after 26 weeks of androgen deprivation therapy, and response of individual lesions will be used for diagnostic classification of the lesions on baseline imaging among responding patients. A response is defined as PSA normalisation or ≥ 80% reduction compared with baseline levels, testosterone below castration levels

The purpose of this study was to investigate the diagnostic performance of 68 Ga-PSMA-11 PET/CT in the evaluation of bone metastases in metastatic prostate cancer (PC) patients scheduled for radionuclide therapy in comparison to [ 18 F]sodium fluoride ( 18 F-NaF) PET/CT. Sixteen metastatic PC patients with known skeletal metastases, who underwent both 68 Ga-PSMA-11 PET/CT and 18 F-NaF PET/CT for assessment of metastatic burden prior to radionuclide therapy, were analysed retrospectively. The performance of both tracers was calculated on a lesion-based comparison. Intensity of tracer accumulation of pathologic bone lesions on 18 F-NaF PET and 68 Ga-PSMA-11 PET was measured with maximum standardized uptake values (SUV max ) and compared to background activity of normal bone. In addition, SUV max values of PET-positive bone lesions were analysed with respect to morphologic characteristics on CT. Bone metastases were either confirmed by CT or follow-up PET scan. In contrast to 468 PET-positive lesions suggestive of bone metastases on 18 F-NaF PET, only 351 of the lesions were also judged positive on 68 Ga-PSMA-11 PET (75.0%). Intensity of tracer accumulation of pathologic skeletal lesions was significantly higher on 18 F-NaF PET compared to 68 Ga-PSMA-11 PET, showing a median SUV max of 27.0 and 6.0, respectively (p PET, with a median SUV max of 1.0 in comparison to 2.7 on 18 F-NaF PET; however, tumour to background ratio was significantly higher on 18 F-NaF PET (9.8 versus 5.9 on 68 Ga-PSMA-11 PET; p = 0.042). Based on morphologic lesion characterisation on CT, 18 F-NaF PET revealed median SUV max values of 23.6 for osteosclerotic, 35.0 for osteolytic, and 19.0 for lesions not visible on CT, whereas on 68 Ga-PSMA-11 PET median SUV max values of 5.0 in osteosclerotic, 29.5 in osteolytic, and 7.5 in lesions not seen on CT were measured. Intensity of tracer accumulation between 18 F-NaF PET and 68 Ga-PSMA-11 PET was significantly higher in osteosclerotic (p�

Background. Brain metastases are common patterns of dissemination in lung cancer patients. In this paper we would like to assess the pattern of brain metastases in lung cancer patients and the impact of prognostic factors on the survival of lung cancer patients with brain metastases. Patients and methods. In the year 1998 there were 974 registered patients with lung cancer in Slovenia, six hundred and fifteen of them were treated at the Institute of Oncology Ljubljana and we analyzed them. Among 615 patients 137 (22.3 %) of them have had brain metastases during a natural course of disease. Results. For 12 patients presenting with solitary brain metastases (most of them were undertaken metastasectomy) median survival was 7.6 months, while in patients with multiple brain metastases the median survival was 2.8 months (p 0.0018). Of the 137 patients 45 (32.8 %) were small cell lung cancer patients, 43 (31.4 %) were adenocarcinoma patients and 19 (13.9 %) were squamous cell carcinoma patients. Patients with performance status (WHO scale) less than 2 had the median survival time 3.7 months while patients with performance status 2 or more had median survival time 2.7 moths (p=0.0448). Conclusions. Patients with solitary brain metastases had better survival comparing with those who had multiple metastases. It is surprisingly that the portion of brain metastases patients with adenocarcinoma is almost equal to those with small-call lung cancer therefore, the prophylactic cranial radiation becomes actual for both groups of patients. The performance status of patients with brain metastases remains very important prognostic factor. (author)

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

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.

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

In the pre-treatment work-up in breast carcinoma cases, the bone scan findings could be of major interest. If the presence of occult metastases is discovered management may be modified accordingly. In a group involving 78 cases of breast carcinoma, classified as primary, operable, in three cases only scintigraphy revealed bone metastases before they produced clinical and radiological signs. In two of them there was agreement, in one disagreement over the findings. Moreover, in 5 cases a bone metastasis was revealed and immediately confirmed on a complete bone assessment.

Breast cancer with stomach metastasis rare with an incidence of 1% or less among metastatic breast cancer patients. We experienced a case of breast cancer metastasizing to the stomach in 65-year-old female patient. She experienced dyspepsia and poor oral intake before visiting the clinic. Diffuse infiltration with nodular mucosal thickening of the stomach wall was observed, suggesting advanced gastric cancer based on gross endoscopic finding. Spread of poorly cohesive tumor cells in the gastric mucosa observed upon hematoxylin and eosin stain resembled signet ring cell carcinoma, but diffuse positive staining for GATA3 in immunohistochemical stain allowed for a conclusive diagnosis of breast cancer metastasizing to the stomach. Based on the final diagnosis, systemic chemotherapy was administered instead of primary surgical resection. After 2 cycles of docetaxel administration, she showed a partial response based on abdominal computed tomography scan. This case is an unusual presentation of breast cancer metastasizing to the gastrointestinal tract.

BACKGROUND: The ability of colour Doppler, power Doppler and echo-enhanced Doppler imaging to detect the blood flow in liver metastases from colorectal cancer was investigated. An evaluation was then made to determine whether the flow pattern could be used as an indication of disease elsewhere....... METHODS: Forty-two patients with hepatic metastases from colorectal cancer were examined, 8 of whom had local recurrence of their colorectal cancer. Seventy-seven liver metastases were evaluated with colour Doppler and power Doppler, and the presence or absence of a Doppler signal in the halo or centre...... was noted. Forty-three of these metastases were further examined after contrast media echo-enhancement. RESULTS: Signals from the peripheral halo were detected by colour Doppler imaging in 34% of the metastases, and in 77% by power Doppler (P power Doppler...

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.
