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

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

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

    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

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

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

    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.

    Many tumors (like prostate- and breast cancer) induce osseous metastases that need to be treated. Bone targeted radionuclide therapy should be performed at an early stage in patients with painful bone metastases and scintigraphically positive lesions. The combination of external beam irradiation and systemic administration of radionuclides is often advantageous and can be performed without clinical problems. In patients with hormone-refractory prostate cancer and bone metastases, radionuclide therapy is increasingly performed as antitumor treatment for asymptomatic patients in clinical trials. By randomised, controlled clinical phase-II studies, it has been shown that new therapy regimens can prolong the progression-free interval and overall survival. New protocols that have been proposed represent the simultaneous application of chemotherapy and radionuclides. Side effects of such protocols are kept within a low toxicity level by reducing the dose of the chemotherapeutic agent (low-dose-chemotherapy). This combined therapy approach, however, is able to generate a radiosensitive state in the tumor cells resulting in an increased tumoricide efficiency of radionuclides. A different, innovative approach is the administration of multiple radionuclide injections at defined time intervals aiming at killing tumor cells with higher radiation doses. Side effects of these new treatment regimens can be scored as moderate. Consequently, in hormone-refractory prostate cancer patients, such new protocols should be considered as an alternative treatment option after standardised therapy regimens have been accomplished. In this situation, extensive experience for treating and selecting appropriate patients is crucial. A randomised pase-III study for the prove of an increased progression-free interval and overall-survival by radionuclide therapy is still missing. (orig.)

    Full Text Available Skeletal metastases are severe complications in the course of cancer, and they indicate a worse prognosis. The use of modern imaging techniques allows rapid diagnosis of bone metastases. Properly selected diagnostic imaging (scintigraphy, positron emission tomography, whole body MRI allows us to evaluate the number of metastatic foci in the skeletal system. Complementary imaging examinations (X-ray, computed tomography, magnetic resonance imaging determine the extent of metastasis and its character: osteolytic, osteoblast, mixed. Hypercalcaemia is a symptom of low specificity for metastatic bone disease (a result of osteolysis; nevertheless, it is a significant complication in oncological treatment and worsens the prognosis of the patient. A biopsy is the final stage of the diagnostic process, which allows us to assess cell and tissue changes. Guided biopsies are performed under the control of musculoskeletal imaging methods (CT, MRI and they are the most promising tools in bone metastases diagnosis. The development of guided biopsy techniques has led to the conclusion that they should be standard in diagnosing bone metastases. Liquid biopsy (LB seems to be the most promising diagnostic method for detection of bone metastases. LB based on tumour-specific DNA mutation gives an opportunity for early detection and assessment of the molecular heterogeneity of the overall disease.

    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

    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.

    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.

    Treatment of patients with multiple bone metastases accompanied by pain syndrome is a complicated clinical task. Radionuclide therapy is one of its solutions, which is used to achieve long reduction of pain syndrome and significant improvement the quality of patients' life. However mechanism of action of bone-seeking radiopharmaceuticals suggests not only pain control but antitumor effect as well. In early clinical studies of safety and efficacy of the most common bone-seeking radiopharmaceuticals in single administration there were not any preferences in overall survival but individual clinical cases with extraordinary tumor regression after radionuclide therapy were reported. Repeated bone targeted therapy and combination with other treatment modalities can help to gain statistical significant increase in overall survival of patients.

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

    In breast cancer patients, the American Society of Clinical Oncology recommends systemic treatment with radionuclides if multiple symptomatic bone metastases are present or if pain reoccurs in a previously irradiated region. There is evidence that targeted therapy with strontium-89 chloride, samarium-153 EDTMP and rhenium-186 HEDP provides effective pain therapy in 60-80% of patients. As an adjuvant to local radiotherapy, strontium-89 can delay the appearance of new metastases and prolong the intervention-free interval. Cost-effectiveness has been proved for this treatment. Side effects of therapy are moderate. Using the standard dosage discussed, thrombo- and leukopenia will not reach a toxicity higher than grade II (WHO) if pretherapeutic blood counts and bone marrow reserve are normal. Recent data show that a combination of chemotherapy and treatment with strontium-89 can prolong survival time in prostate cancer patients with osseous metastases. (orig.)

Strontium-89 Chlorid kann darueber hinaus, wenn es adjuvant zur perkutanen Bestrahlung eingesetzt wird, das Auftreten von neuen Metastasen verzoegern und das interventionsfreie Intervall verlaengern.

    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

    To find vertebral metastases with high risk of symptomatic malignant spinal cord compression (MSCC), features of vertebral metastases caused motor deficits of the lower extremities were examined. From 2004 through 2006, 78 patients with metastases of the thoracic and/or the cervical spine were treated with radiation therapy (RT). Of these, 86 irradiated lesions in 73 patients were evaluable by magnetic resonance imaging and/or computed tomography at the initiation of RT and were reviewed retrospectively in this study. Twenty-eight patients (38%) had motor deficits at the initiation of RT. Assessed factors were age, sex, primary disease (lung, breast, digestive system and other cancer), lamina involvement, main level of tumor location and vertebral-body involvement. Incidence of motor deficits at the initiation of RT was 55% for lesions with lamina involvement and 5% for lesions without lamina involvement (P 0.9999, P=0.7798, P=0.1702 and P=0.366, respectively). Vertebral metastases with lamina involvement tended to cause symptomatic MSCC. Latent development of MSCC occurred more frequently in the MTS compared with other levels of the thoracic and the cervical spine. (author)

    AIM: The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS: Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the study. We used a scoring system to grade the scintigraphic abnormalities. The patients' symptoms and scintigraphic findings were recorded. RESULTS: Though focally increased radiopharmaceutical uptake was observed in all symptomatic accessory naviculars, half of the asymptomatic accessory navicular bones had the same manifestations. The scoring system was of no value in differentiating symptomatic from asymptomatic accessory navicular bones. CONCLUSION: Bone scintigraphy is a sensitive but not a specific tool for diagnosing a symptomatic accessory navicular. Chiu, N.-T. (2000)

    Imatinib has revolutionized the treatment and prognosis of patients with gastrointestinal stromal tumors (GIST). In contrast to liver and/or abdominal involvement, bone metastases are an uncommon event in GIST. We report here two patients with metastatic GIST who developed pelvic bone marrow focal lesions visible on MRI examinations, while Imatinib dramatically improved other tumor sites. A biopsy in one patient diagnosed bone marrow necrosis. The other patient had a favorable follow-up over several years, without bone metastases. Focal bone marrow abnormalities, detected on MRI examinations and mimicking bone metastases in patients who were otherwise responding, should be considered as probable bone marrow necrosis. (orig.)

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

  7. 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.

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

    Full Text Available 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.

    Full Text Available Metastases to the skeletal system are commonly observed in cancer patients, highly affecting the patients' quality of life. Imaging plays a major role in detection, follow-up, and molecular characterisation of metastatic disease. Thus, imaging techniques have been optimised and combined in a multimodal and multiparametric manner for assessment of complementary aspects in osseous metastases. This review summarises both application of the most relevant imaging techniques for bone metastasis in preclinical models and the clinical setting.

    Full Text Available Bladder cancer rarely presents clinically with a myelophthisic picture from diffuse bone marrow infiltration especially in the absence of detectable skeletal metastases. A 75-year old man presented with newly diagnosed urothelial cell carcinoma of the bladder. Pathology from transurethral resection of bladder tumor demonstrated muscle-invasive disease. Pre-therapy imaging including CT abdomen/pelvis, CXR and bone scan demonstrated liver lesions concerning for metastatic disease but no skeletal metastases. Labs were notable for isolated thrombocytopenia, hypercalcemia and acute kidney injury prompting hospitalization. Hematologic work-up including bone marrow aspiration and biopsy revealed diffuse infiltration of the bone marrow by urothelial cancer. The case illustrates the importance of fully investigating otherwise unexplained clinical findings in patients with clinically localized urothelial cancer prior to curative intent surgery.

    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.

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

    We analyzed clinical factors related to uptake on a Tc-99 m HDP bone scan of the accessory navicular (AN). We retrospectively reviewed patients who had been examined by an orthopedic surgeon and underwent bone scan due to suspected symptomatic AN. A three-point grading system was used to evaluate uptake on bone scan. Relationships between grade, symptoms, age, gender, symptom duration, and bone size were analyzed. In total, 73 ANs (30 asymptomatic, 43 symptomatic) were enrolled. The majority of asymptomatic ANs had no uptake but some had grade 1 (n = 8) or 2 (n = 2) uptake. All asymptomatic ANs with uptake remained asymptomatic during follow-up. For the asymptomatic ANs, larger bones showed a higher grade. With a cut-off value of size ≤6.8 mm, there is no chance of uptake. All symptomatic ANs showed uptake on bone scan. For symptomatic ANs, larger size and shorter pain duration were related to a higher grade. Age, gender, and left-/right-sideness were not related to grade. Multiple regressions revealed that only uptake grade, not size or symptom duration, was the significant risk factor for a symptomatic AN. With a cut-off value of grade <1, a symptomatic AN could be ruled out with a negative predictive value of 100 %. Bone scanning is useful for symptomatic ANs with a high negative predictive value. Higher grade is related to larger size and shorter pain duration. For asymptomatic ANs, grade was related to size but did not predict symptom development.

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

    Radiation therapy (RT) is frequently used to palliate symptomatic bone metastases. While high quality literature has shown that for uncomplicated bone metastases, shorter radiotherapy courses are just as effective as longer courses for the treatment of pain, shorter courses remain under-utilized. We aimed to assess the impact of a dedicated palliative radiation oncology service on the frequency of single fraction RT (SF-RT) and hypofractionated radiation (hypo-RT) (≤5 fractions) among patients with bone metastases. We identified 2,086 instances of palliative radiation (RT) for complicated and uncomplicated bone metastases between April 10, 2008 and September 17, 2014. We used multivariable logistic regression analysis (MVA) to estimate the association of the Supportive and Palliative Radiation Oncology (SPRO) service with the likelihood of receiving SF-RT or hypo-RT after controlling for age, sex, tumor type, and treatment site. Prior to SPRO's implementation on July 1, 2011, the proportion of SF-RT and hypo-RT for bone metastases was 6.4% and 27.6% respectively. After SPRO's implementation, the proportion of SF-RT and hypo-RT increased to 22.3% (Pdedicated palliative service, patients receiving care at the SPRO affiliated department were more likely to receive SF-RT (OR =1.9, 95% CI =1.1-3.2, P=0.02) and hypo-RT (OR =1.5, 95% CI =1.1-2.0, P=0.004) for bone metastases. After SPRO's implementation, the average number of RT courses delivered for bone metastases increased from 17.4 to 25.6 per month, (+8.3, 95% CI =4.99-11.55, Pdedicated palliative radiation oncology service was associated with increased use of SF and hypo-RT and with greater courses of RT delivered for bone metastases.

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

    The differential diagnosis of multiple cranial nerve palsies in patients with cancer includes meningeal infections, meningeal carcinomatosis, and skull base metastases. In distinguishing these, spinal fluid analysis and skull base tomography should be helpful in most cases. In circumstances when results of skull base tomography are negative, radionuclide bone scans can demonstrate metastatic disease in the base of the skull, and it should be obtained in all patients who are highly suspicious for having skull base metastasis with negative skull base tomography, including computed tomography (CT).

This guidance is based on an interdisciplinary consensus. These recommendations are a prerequisite for the quality management in the treatment of patients with bone metastases from prostate cancer using (223)Ra. They are aimed at guiding nuclear medicine specialists in selecting candidates to receive therapy and to deliver the treatment in a safe and effective manner. The document contains background information and definitions. It covers the rationale, indications and contraindications for therapy with (223)Ra. Essential topics are the requirements for institutions performing the therapy, which patient data have to be available prior to performance of therapy, and how treatment has to be carried out technically and organisationally. Moreover, essential elements of follow-up and aftercare are specified. As a matter of principle, the treatment inclusive aftercare has to be realised in close cooperation with the involved medical disciplines.

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

    Bone metastasis is a frequent finding in the natural history of several types of cancers. However, its anticipated risk, diagnosis and response to therapy are still challenging to assess in clinical practice. Markers of bone metabolism are biochemical by-products that provide insight into the tumor–bone interaction, with potential to enhance the clinical management of patients with bone metastases. In fact, these markers had a cornerstone role in the development of bone-targeted agents; however, its translation to routine practice is still unclear, as reflected by current international guidelines. In this review, we aimed to capture several of the research and clinical translational challenges regarding the use of bone metabolism markers that we consider relevant for future research in bone metastasis.

    We conducted a large, multicenter, retrospective survey aimed to explore the impact of tumor bone involvement in Non-Small Cell Lung Cancer.Data on clinical-pathology, skeletal outcomes and bone-directed therapies for 661 deceased patients with evidence of bone metastasis were collected and statistically analyzed. Bone metastases were evident at diagnosis in 57.5% of patients. In the remaining cases median time to bone metastases appearance was 9 months. Biphosphonates were administered in 59.6% of patients. Skeletal-related events were experienced by 57.7% of patients; the most common was the need for radiotherapy. Median time to first skeletal-related event was 6 months. Median survival after bone metastases diagnosis was 9.5 months and after the first skeletal-related event was 7 months. We created a score based on four factors used to predict the overall survival from the diagnosis of bone metastases: age >65 years, non-adenocarcinoma histology, ECOG Performance Status >2, concomitant presence of visceral metastases at the bone metastases diagnosis. The presence of more than two of these factors is associated with a worse prognosis.This study demonstrates that patients affected by Non-Small Cell Lung Cancer with bone metastases represent a heterogeneous population in terms of risk of skeletal events and survival.

    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.

    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 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

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

    Full Text Available Denise A Yardley1,2 1Sarah Cannon Research Institute, Nashville, TN, USA; 2Tennessee Oncology, Nashville, TN, USA Abstract: There is a high risk for bone loss and skeletal-related events, including bone metastases, in postmenopausal women with hormone receptor-positive breast cancer. Both the disease itself and its therapeutic treatments can negatively impact bone, resulting in decreases in bone mineral density and increases in bone loss. These negative effects on the bone can significantly impact morbidity and mortality. Effective management and minimization of bone-related complications in postmenopausal women with hormone receptor-positive breast cancer remain essential. This review discusses the current understanding of molecular and biological mechanisms involved in bone turnover and metastases, increased risk for bone-related complications from breast cancer and breast cancer therapy, and current and emerging treatment strategies for managing bone metastases and bone turnover in postmenopausal women with hormone receptor-positive breast cancer. Keywords: breast cancer, bone metastases, hormone receptor-positive, bone-related complications, interventions, management and management strategies, estrogen receptor-positive

    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.

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

    Full Text Available 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.

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

    Bone metastases clinic (BMC) is a multidisciplinary clinic where patients with bony metastases are assessed in conjunction by orthopedic surgery, radiation oncology, interventional radiology, and palliative medicine teams. The objective of the study was to determine the number of older adult (OA) referrals made to BMC and to examine their case dispositions. Patients who were referred to the BMC from 2007 to 2015 were included in the study. Demographic information including gender, age, Karnofsky Performance Status (KPS), primary cancer site and reason for referral, as well as case dispositions were recorded for each patient. The proportion of OA attendance was calculated for each year from the total number of patient visits. OA attendance was defined as individuals ≥65 years of age who attended the BMC, and non-OA patients were those statistics were employed. A total of 551 patients were included with a median age of 64 years. The median KPS was 70 for OA and 80 for non-OA patients. OA attendance ranged per year from 42.5% to 58.7%. 14.1% of non-OA and 10.9% of OA patients were offered surgery. 62 patients in both cohorts (22.6% of OA and 22.4% of non-OA patients) were offered palliative radiation. From 2007 to 2015, OA patients comprised a significant proportion of referrals to the BMC. Younger patients were offered surgery slightly more often when compared to OA patients. Age did not appear to be a precluding factor for BMC referral or a deterrent in treatments offered.

    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

  8. Targeted α Therapies for the Treatment of Bone Metastases

    2017-12-01

    Full Text Available The skeleton is the target tissue for many types of tumors, and, recently, the survival of patients with prostate cancer metastasis has been increased using α-emitting drugs known as targeted α therapies. The use of α-radiopharmaceuticals in medicine was hypothesized at the beginning of the nineteenth century after the observation that α-radionuclides were associated with high cell-killing energy and low tissue penetration in healthy tissues. In the prostate cancer (PC scenario, current research suggests that this class of radiopharmaceuticals has limited toxicity, and that the mechanism of action does not overlap with pre-existing drugs, allowing us to extend therapeutic armaments and address medical oncology towards personalized and precision medicine. Ongoing studies may extend these benefits also to bone metastases deriving from other neoplasms. The aim of this review is to summarize the current research on targeted α therapies and try to identify the right patient to be treated in the right time in order to integrate in these medications in the every-day clinical practice.

    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.

    Cancer-associated inflammation has been receiving increased attention due to its role in cancer development. It is known that tumors can cause an inflammatory reaction and inflammatory cells play an important role in neoplastic growth. In this study, we aimed to investigate any relationship between bone metastases and the neutrophil-to-lymphocyte ratio (NLR). Patients who were referred for bone scintigraphy to investigate bone metastasis were enrolled in the study. Patients’ hematological parameters were obtained from the hospital database retrospectively. Patients with a nonmetastatic bone scan were categorized as Group A (N = 171), patients who had metastatic bone disease without any other organ metastases were categorized as group B (N = 25), and patients who had metastatic bone disease with the other organ metastases were categorized as Group C (N = 48). The median NLR of the patients in Group A was 2.55 (range: 0.38–20.7), in Group B was 2.83 (range: 1.56–31.8), and in Group C was 4.12 (range: 1.79–38). NLR was significantly higher in Group C patients compared to Group A and B patients (P < 0.001). In conclusion, the NLR is significantly associated with the other organ metastases but has no significant correlation with bone metastases

    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.

Method: In 128 diagnosed patients with lung cancer, small cell lung cancer were 26 cases, non-small cell lung cancer were 102 cases which included 44 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 4 cases of large cell carcinoma, 4 cases of squamous adenocarcinoma. 99m Tc-MDP whole-body bone scanning was performed in 128 patients with lung cancer. over the same period, the serum samples were collected in these patients and 30 comparison controls. CEA, CA125, CA199, SCC, NSE, CA15-3, and AFP were measured by ELISA technique. Bone imaging findings analysis used t-test, and serum levels of tumor markers analysis used χ 2 test. Results: The diagnostic of 53 cases of lung cancer with bone metastasis was subject to clinical criteria of lung cancer with bone metastases. The positive ratio of patients with osseous metastasis was confirmed by 99m Tc-MDP whole-body bone scanning was 23.44% (30/128), including 16 cases of lung adenocarcinoma, 9 cases of squamous cell carcinoma, 3 cases of small cell lung cancer , 1 case of large cell lung cancer, 1 case of squamous adenocarcinoma and multiple bone metastases accounted for 66.67% (20/30). The levels of serum CEA, CA125, CA199, SCC, NSE and CA15-3 were higher than the control group (P < O.05). 29 cases of CEA positive and 21 cases of CA125 positive were included in 30 cases of lung cancer with bone metastasis. There was a significant difference between the levels of CEA, CA125, CA199, NSE in lung cancer with bone metastases and without bone metastases (P < 0.05). The sensitivity of 99m Tc-MDP whole-body bone scanning in diagnosis of lung cancer with bone metastasis was 84.91%. Conclusion: The average value of CEA, CA125, and CA199, SCC, NSE and CA15-3 in lung cancer patients were significantly higher than the control group. In addition, there is a significantly correlation between the occurrence of

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

    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

    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.

    Full Text Available Abstract Background This practice guideline was developed to provide recommendations to clinicians in Ontario on the preferred standard radiotherapy fractionation schedule for the treatment of painful bone metastases. Methods A systematic review and meta-analysis was performed and published elsewhere. The Supportive Care Guidelines Group, a multidisciplinary guideline development panel, formulated clinical recommendations based on their interpretation of the evidence. In addition to evidence from clinical trials, the panel also considered patient convenience and ease of administration of palliative radiotherapy. External review of the draft report by Ontario practitioners was obtained through a mailed survey, and final approval was obtained from the Practice Guidelines Coordinating Committee. Results Meta-analysis did not detect a significant difference in complete or overall pain relief between single treatment and multifraction palliative radiotherapy for bone metastases. Fifty-nine Ontario practitioners responded to the mailed survey (return rate 62%. Forty-two percent also returned written comments. Eighty-three percent of respondents agreed with the interpretation of the evidence and 75% agreed that the report should be approved as a practice guideline. Minor revisions were made based on feedback from the external reviewers and the Practice Guidelines Coordinating Committee.

    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.)

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

    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

    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.

    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. 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). (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. (223)Ra and (177)Lu hold the highest potential for palliative treatment of bone metastases of all radioisotopes compared in this study.

    To evaluate the effect of CT software that generates rib unfolding images and automatically numbers ribs and thoracic spines on radiologist performance in detecting thoracic bone metastases from breast cancer. A total of 126 patients with breast cancer who underwent chest CT and fludeoxyglucose (FDG)-positron emission tomography (PET)/CT and/or bone scans were retrospectively reviewed. One board-certified radiologist (R1) and one radiology resident (R2) independently assessed the original chest CT and rib unfolding images using a commercially available post-processing software (Bone Reading) application to evaluate metastasis in the ribs and thoracic spines. Results were compared with reference standard based on CT, FDG-PET/CT and/or bone scan with follow-up. Based on reference standard, 78 metastatic bone lesions in 26 patients were identified. On per-patient-based analysis, Bone Reading assessed by R1/R2 had a sensitivity of 84.6%/80.8% and a specificity of 94.0%/94.0% with an accuracy of 92.1%/91.3%. The original CT reading yielded a sensitivity of 73.1%/57.7% and a specificity of 95.0%/94.0% with an accuracy of 90.5%/86.5%. The sensitivity and accuracy of Bone Reading were significantly higher than those of CT reading, as assessed by R2 (both p = 0.031). On per-lesion-based analysis, Bone Reading assessed by R1/R2 yielded a sensitivity of 84.6%/82.1% and a specificity of 99.7%/99.6% with an accuracy of 99.4%/99.3%, while the original CT reading yielded a sensitivity of 71.8%/62.8% and a specificity of 99.6%/99.5% with an accuracy of 99.2%/98.9%. The sensitivity and accuracy with Bone Reading application were significantly higher than those with CT reading by both readers (R1, p = 0.006 and p = 0.036, respectively; R2, both p reading time needed for Bone Reading application was significantly shorter than that for original chest CT reading (p Reading application helped readers find small and sclerotic lesions missed in original CT reading.

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

Oncol. 28(35), 5132-5139 (2010). Bone is the most common site of recurrence in patients with advanced breast cancer. Bisphosphonates have revolutionized the care for patients with bone metastases by delaying and reducing skeletal complications. The RANK ligand inhibitor denosumab has been developed as a result of our enhanced understanding of bone physiology. In a recent randomized, double-blind trial, denosumab has been shown to be superior to zoledronic acid in delaying the onset of skeletal complications in advanced breast cancer patients. While these results are exciting, the absence of any survival benefit and the considerable cost of this agent mean that further quality-of-life data are needed before it becomes widely used as a new standard of care.

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

    International Nuclear Information System (INIS)

    Remi, J.-P.

    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

    Thirty (3.8%) of 780 patients with differentiated thyroid cancer seen between 1970 and 1987 had bone metastases. The primary tumor was follicular in 26 patients and papillary in four. Mean age at diagnosis was 61 years. The manifestation of bone metastases was the presenting symptom in 18 patients (60%). Treatment included total thyroidectomy, levothyroxine sodium therapy, and radioactive iodine treatments. Twenty-seven patients had bone metastases from the initial observation, with 44 sites involved. Of the sites, 27 (61%) were shown both on iodine 131 whole-body scan (WBS) and on x-ray film, 11 (25%) only on WBS, and six (14%) only on x-ray film. Multiple involvement was observed in 11 patients. The radiologic appearance was invariably osteolytic. Serum thyroglobulin was elevated in all patients. After radioactive iodine, no WBS+/X-ray+ metastases showed a complete response, although a sclerotic border was noted in several cases, whereas six WBS+/X-ray- lesions were no longer detectable by WBS. Treatment with radioactive iodine and bone surgery resulted in a complete cure in three patients and in a reduction of tumor mass in three. Twenty-one (70%) of the patients died of thyroid cancer after a mean survival of 86 months. Of the nine patients still alive, two are free of disease, three have a good quality of life, and four have severe disability.

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

    Key Clinical Message The patient developed multiple bone metastases following mastectomy with silicone reconstruction and contralateral augmentation for ductal carcinoma in situ (DCIS) of the breast. She was diagnosed with contralateral invasive cancer. Distant metastasis of DCIS is rare, and other metastatic origins must be screened. However, screening of augmented breasts is difficult.

    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.

    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)

    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.

    This study examined the usefulness of diffusion-weighted (DW) Magnetic Resonance Imaging (MRI) in monitoring bone metastases response to radiation therapy in 15 oligometastatic patients. For each metastasis, both mean apparent diffusion coefficient (ADC) changes and high b-value DW metastasis/muscle signal intensity ratio (SIR) variations were evaluated at 30 ± 5 days and 60 ± 7 days after the end of treatment. On baseline DW-MRI, all bone metastases were hyperintense and had signal intensities higher than normal bone marrow on calculated ADC maps. At follow-up evaluations, 4 patterns of response were identified: (I) decreased high b-value DW SIR associated with increased mean ADC (83.3% of cases); (II) increased mean ADC with no change of high b-value DW SIR (10% of cases); (III) decreased both high b-value DW SIR and mean ADC (3.3% of cases); (IV) a reduction in mean ADC associated with an increase in high b-value DW SIR compared to pretreatment values (3.3% of cases). Patterns (I) and (II) suggested a good response to therapy; pattern (III) was classified as indeterminate, while pattern (IV) was suggestive of disease progression. This pattern approach may represent a useful tool in the differentiation between treatment-induced necrosis and highly cellular residual tumor. 1. Introduction

    The objective of this study was to determine if dual-energy computed-tomography bone marrow color maps can improve sensitivity, specificity, accuracy, and confidence of detection of bone metastases. Institutional review board approved this retrospective review of a consecutive series of cancer patients. Two radiologists first evaluated the fused 120 kV computed tomography images and recorded a number of suspicious lesions, confidence level, and Hounsfield units for each lesion. After a time gap, the studies were randomized for a second review with dual-energy computed-tomography bone marrow color maps. Eighteen patients and 1105 bones were reviewed. A total of 227 true metastatic lesions were present. With bone marrow color map review, sensitivity increased from 76.2% to 86.8%, for reader 1, and from 80.2% to 92.8%, for reader 2. Specificity and accuracy also increased. Confidence level increased for 12 lesions. Dual-energy computed-tomography bone marrow color map analysis of patients with metastatic cancers can improve the sensitivity, specificity, accuracy, and confidence level for the detection of bone metastases.

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

    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

    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.

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

    Purpose: 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

    To evaluate the clinical outcomes of symptomatic bone lesions in patients with multiple myeloma (MM) who received local radiotherapy (LRT). Fifty-one patients with 87 symptomatic bone lesions treated via LRT were analyzed. LRT was delivered at a median total dose of 21 Gy (range, 12 to 40 Gy) in a median of 7 fractions (range, 4 to 20 fractions). The clinical outcomes of LRT and the factors affecting treatment response were assessed. After a median follow-up time of 66.7 weeks, symptom relief was achieved for 85 of 87 lesions (97.7%). The median time to symptom relief was 7 days from the start of LRT (range, 1 to 67 days). The duration of in-field failure-free survival ranged from 1.1 to 450.9 weeks (median, 66.7 weeks). The radiation dose or use of previous and concurrent chemotherapy was not significantly associated with in-field failure for LRT (p = 0.354, 0.758, and 0.758, respectively). Symptomatic bone lesions in patients with MM can be successfully treated with LRT. A higher radiation dose or the use of concurrent chemotherapy may not influence the in-field disease control. A relatively low radiation dose could achieve remission of symptoms in patients with MM.

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

    Directory of Open Access Journals (Sweden)

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

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

    Taking into consideration the different radiation procedures reported in literature and related dosage problems, palliative fractionated radiation therapy of bone metastases of mammary carcinoma with a low radiation dose of 25 Gy HD (2,500 rad) was critically assessed. For the evaluation 106 patients treated between 1964 and 1976 were considered. The radiation results were as follows: a subjective reaction rate of 95 per cent with 80 per cent disappearance of pain lasting as a rule till the end of the patients' life. An objective reaction rate of, on the whole, 78 per cent with distinct recalcification respectively conversion of osteolysis into osteoplasy in 56 per cent of the cases. No response to the radiation therapy was only seen in 5 per cent each. The patients' total survival time was 50 months on average with a median of 41 months. The life time from the diagnosis of bone metastases, corresponding to the beginning of radiation therapy, to the patients' death was 18 months on average with a median of 12 months. Radiation therapy to palliate the fiercest pain caused by bone metastases is a method so far unequalled. Generally it can be said that radiation therapy for bone metastases should be applied with some flexibility. It is to be seen in close relation to each patient's individual set of problems. According to the current state of knowledge prolonged radiation courses with high doses (50 Gy) should where possible be avoided because of the late manifestations and high psychic stress. By contrast, relatively low-dosed (10 Gy) single-time irradiation can be the most appropriate treatment of patients in the terminal stage. (orig./MG) [de

    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.

  9. Pheochromocytoma presenting as musculoskeletal pain from bone metastases

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

    Introduction: In patients with neuroendocrine gastrointestinal tumors and liver metastases, but without known extrahepatic manifestations, liver transplantation may be indicated as curativ or 'long-term-palliativ' therapy. For these patients the absence of bone lesions is mandatory. Methods: 4 patients with a histologically proven neuroendocrine tumor were examined in order to exclude further metastases. We compared the diagnostic value of somatostatin-receptor-scintigraphy (SRS), X-ray, 99 m Tc-DPD-scintigraphy, CT and MRI. Results: In all 4 patients bone metastases could be detected using SRC, CT and MRT. In one case MRI proved multiple infiltrations, while SRS showed only a solitary, focal lesion. 99 m Tc-DPD-scintigraphy was positive in 3 cases, X-ray in 1 case. Conclusion: As a diagnostic strategy we initially recommend somatostatin-receptor-scintigraphy. When locating suspect areas in SRS, MRI should be the method of choice for the exact evaluation of malignant bone infiltrations. A CT-guided biopsy is necessary to gain histological information.

    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

    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

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

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

    Targeted therapies have improved patient survival in metastatic lung adenocarcinoma. Molecular diagnosis is a key element to identify oncogenic drivers predicting the efficacy of these agents. In stage IV patients, histopathological diagnosis is often performed on bone metastases biopsy, but routine procedure of decalcification may alter DNA quality for subsequent molecular tests. We set up a procedure to perform molecular analyses on bone metastasis and describe the results of mutational profiling. POUMOS-TEC is a prospective study conducted in stage IV lung adenocarcinomas. Bone metastasis specimens from surgery and CT-scan guided biopsies were sent fresh for immediate formalin-fixation. Decalcification was performed, only when necessary, using EDTA. Controls were processed with acid decalcification. DNA extraction was performed after laser microdissection. Mutational profiling of oncogenic drivers was conducted as recommended by the French National Cancer Institute. Diagnosis efficiency of the computed tomography (CT)-scan guided biopsy process was assessed. Among 177 collected bone metastases specimens, 49 came from lung adenocarcinomas. Specimens processed with no decalcification or EDTA (n=45) provided high-quality DNA. Molecular profiling was performed in 44/45 (98%) of cases. The results of the whole panel of oncogenic drivers (EGFR, KRAS, BRAF, PIK3CA, HER2 and ALK) were obtained in 41/45 (91%) of cases. A mutation was observed in 50% of cases including 32% of KRAS and 14% of epidermal growth factor receptor (EGFR) mutations. CT-scan biopsy efficiency rate was 96%. We demonstrated the feasibility to routinely conduct mutational profiling on bone metastases biopsies. We observed a higher rate of EGFR mutations (+42%) in comparison with the average rate of all stage IV lung adenocarcinomas. This procedure is a new step toward the goal of personalized medicine to treat lung cancers and other osteophilic tumors.

    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

    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.

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

    To compare the effects of resistance training versus passive physical therapy on bone survival in the metastatic bone during radiation therapy (RT) as combined treatment in patients with spinal bone metastases. Secondly, to evaluate overall survival and progression-free-survival (PFS) as well as to quantify prognostic factors of bone survival after combined treatment. In this randomized trial 60 patients were allocated from September 2011 until March 2013 into one of the two groups: resistance training (group A) or passive physical therapy (group B) with thirty patients in each group during RT. We estimated patient survival using Kaplan-Meier survival method. The Wald-test was used to evaluate the prognostic importance of pathological fracture, primary site, Karnofsky performance status, localization of metastases, number of metastases, and cerebral metastases. Median follow-up was 10 months (range 2-35). Bone survival showed no significant difference between groups (p = .303). Additionally no difference between groups could be detected in overall survival (p = .688) and PFS (p = .295). Local bone progression was detected in 16.7 % in group B, no irradiated bone in group A showed a local progression over the course (p = 0.019). In univariate analysis breast cancer, prostate cancer, and the presence of cerebral metastases had a significant impact on bone survival in group B, while no impact could be demonstrated in group A. In this group of patients with spinal bone metastases we were able to show that guided resistance training of the paravertebral muscles had no essential impact on survival concomitant to RT. Importantly, no local bone progression in group A was detected, nevertheless no prognostic factor for combined treatment could be evaluated. Clinical trial identifier NCT 01409720 .

    1999-01-01

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

    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

  5. Modeling invasion of metastasizing cancer cells to bone marrow utilizing ecological principles.

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

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

    To document the incidence and timing of radiotherapy-induced nausea and vomiting (RINV) in the treatment of bone metastases among patients receiving prophylaxis with a 5-HT(3) receptor antagonist. Patients receiving single (SF) or multiple fraction (MF) palliative radiotherapy (RT) of moderate or low emetogenic risk for bone metastases were prescribed prophylactic Ondansetron. The frequency and duration of prophylaxis and the use of rescue antiemetics were left to the discretion of the treating physicians. Patients documented episodes of nausea (N) and vomiting (V) in daily diaries before and during RT, and until 10 days following RT completion. Rates of complete prophylaxis (CP) for N&V, respectively (CP = no event and no rescue medication), were calculated for the acute phase (the period from the start of RT to the first day following RT completion inclusive) and the delayed phase (the second to tenth days following RT completion inclusive). Fifty-nine patients were enrolled, and 32 were evaluable. CP rates were as follows: moderate-risk SF group (n = 16), acute phase (CP for N = 56%, CP for V = 69%) and delayed phase (CP for N = 31%, CP for V = 44%); moderate-risk MF group (n = 7), acute phase (CP for N = 71%, CP for V = 57%) and delayed phase (CP for N = 43%, CP for V = 57%); low-risk SF group (n = 8), acute phase (CP for N = 50%, CP for V = 100%) and delayed phase (CP for N = 43%, CP for V = 57%); and low-risk MF group (n = 1), acute phase (CP for N = 100%, CP for V = 100%) and delayed phase (CP for N = 100%, CP for V = 100%). Despite prophylaxis, RINV was common among patients receiving palliative radiotherapy for bone metastases, especially during the delayed phase.

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

    2011-01-01

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

Bisphosphonate treatment for bone metastases is frequently administered via intravenous infusion, while a newer treatment is administered as a subcutaneous injection. This study estimated the impact of these treatment modalities on health state preference. Methods: Participants from the UK general population completed time trade-off interviews to assess the utility of health state vignettes. Respondents first rated a health state representing cancer with bone metastases. Subsequent health states added descriptions of treatment modalities (ie, injection or infusion to this basic health state. The two treatment modalities were presented with and without chemotherapy, and infusion characteristics were varied by duration (30 minutes or 2 hours and renal monitoring. Results: A total of 121 participants completed the interviews (52.1% female, 76.9% white. Cancer with bone metastases had a mean utility of 0.40 on a standard utility scale (1 = full health; 0 = dead. The injection, 30-minute infusion, and 2-hour infusion had mean disutilities of −0.004, −0.02, and −0.04, respectively. The mean disutility of the 30-minute infusion was greater with renal monitoring than without. Chemotherapy was associated with substantial

    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

    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

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

    The authors assessed the adequacy and sensitivity of CT-guided bone biopsy in 308 procedures performed in 286 cancer patients with suspected bone metastases. An electronic search of our CT-guided bone biopsy database was retrospectively performed to evaluate the adequacy of samples and, in the event of negative samples, whether the patients had radiological progression at the site of biopsy (false negative). Adequacy and false-negative rate were compared with radiological features, biopsy location, specimen length and complications to assess any statistically relevant association with a multivariate logistic regression model. A total of 290/308 (94.1 %) samples were adequate. Forty-five patients had normal bone marrow and were followed-up, with evidence of progression at the site of biopsy in 10 cases (false-negative cases); overall sensitivity was 96.7 %. Specimen length was significantly correlated to the probability of an adequate biopsy (p = 0.035) and inversely correlated to the probability to obtain a false-negative result (p = 0.02). We encountered 11/308 (3.5 %) minor complications and no major complications. CT-guided biopsy of bone lesions in cancer patients allows for a final diagnosis in 94 % of cases. A specimen longer than 1 cm may lead to a significant result in terms of adequacy and sensitivity. Negative biopsies with positive positron emission tomography or magnetic resonance imaging and specimen shorter than 1 cm should be repeated to avoid a false-negative result.

    The dorsal patellar defect is a relatively rare entity that involves the superolateral quadrant of the patella. It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity. Furthermore, the presented case shows that symptomatic dorsal patellar defects can be treated conservatively with success and that (decrease of) pain symptoms are likely related to (decrease of) bone marrow edema.

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

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

    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.

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

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

    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

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

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

    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

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

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

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

    Complete text of publication follows: Distant metastases are found at diagnosis or during follow-up in 10%-15% of patients with differentiated thyroid cancer. Bone is the second most commonly involved site. Patients with bone metastases, whether isolated or associated with lung metastases, have a markedly poor prognosis. Ten-year survival rates range from 13% to 21%. Given such poor prognosis, the use of 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

    Surgical castration is still considered the 'gold standard' for androgen deprivation therapy which have become the mainstay for the management of advanced prostate cancer. The main drawback of this safe operation is that it may have a negative psychological effect, thus, in recent years, a decline in the utilization of bilateral orchiectomy which is the most cost-effective form of androgen deprivation therapy can be witnessed. Testicular prostheses have been shown to reduce the psychological impact resulting from loss or absence of a testicle in those patients. Besides, patients with advanced prostate cancer are at risk of skeletal complications and bisphosphonates are used in treatment. Zoledronic acid is the only bisphosphonate agent demonstrated to effectively reduce skeletal related events in patients with advanced prostate cancer metastatic to bone. Therefore, zoledronic acid releasing testicular prostheses can be used in the treatment of prostate cancer patients with bone metastases after bilateral orchiectomy. This technology has the potential to become the preferred clinical management tool for prostate cancer patients with bone metasthases after bilateral orchiectomy.

    The present study was undertaken to identify patient populations at high risk for bone metastases (BM) at any time after diagnosis of operable breast cancer. A total number of 59 cases with breast cancer after mastectomy was subdivided into two main groups that included 30 patients with radiologically confirmed BM and 29 patients with no bone metastasis (NBM). Patients with NBM were formerly observed for a one-year follow-up interval to monitor the development of bone metastasis (new BM). Parameters included a full blood picture, tumour markers (carcinoembryonic antigen and CA 15.3) and some biochemical markers (vascular endothelial growth factor and zinc levels, as well as tartrate-resistant acid phosphatase and alkaline phosphatase activities). A significant elevation was recorded in carcinoembryonic antigen level and alkaline phosphatase activity, as well as inflammation and vascularisation markers at the time of primary diagnosis in patients with BM, compared with those without BM. CA 15.3 was significantly higher in the new BM group as compared with the other two groups (patients free of bone metastasis [free BM] and BM). According to the likelihood ratio, a panel of single, calculated as well as combined markers was proposed to predict BM within one year in breast cancer patients. Vascularisation and inflammation markers, as well as CA 15.3 are predictive of bone recurrence within one year in breast carcinoma patients. We suggest that in cancer validation studies it is imperative to search for markers that link to the premetastatic process and to determine what type of mechanism is active in each stage.

    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.

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

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

    The role of radiotherapy in stabilizing metastatic bones is unclear. This systematic review assessed the effects of (1) radiotherapy, (2) radiotherapy combined with bisphosphonates, and (3) radiotherapy combined with RANK ligand (RANKL) inhibitors on bone quality and bone strength in bone metastases originating from solid tumors. Pubmed, EMBASE and the Cochrane Library were searched. Any type of study design and type and dose of radiotherapy, bisphosphonates and RANKL inhibitors were allowed. 39 articles were identified. Animal studies showed that radiotherapy had similar effects on bone quality and strength as receiving no treatment, whereas adding bisphosphonates to radiotherapy restored bone quality and strength. In patient studies, bone density increased after radiotherapy and radiotherapy combined with bisphosphonates. However, due to the often non-optimal study design and study quality, it was unclear whether this increase could be attributed to these treatments. There was insufficient evidence to assess the additional effect of bisphosphonates or RANKL inhibitors. Despite the clinical experience that radiotherapy is an effective treatment for bone metastases, there was no sufficient evidence for a positive effect on bone quality and fracture risk. Animal studies showed that adding bisphosphonates to radiotherapy restored bone quality and strength, whereas this was not proven in patients. There were no studies addressing the adjunct effect of RANKL inhibitors to radiotherapy. Although associated with several methodological, practical and ethical challenges, randomized controlled trials are needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

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

    In this paper,the value of differentiating metastases from benign of bone lesions in patients with hepatocellular carcinoma using SPECT/ CT fusion imaging is evaluated. From patients with hepatocellular carcinoma (HCC) confirmed by pathology underwent bone scintigraphy, 97 patients were selected to undergo SPECT/CT scanning. The bone scintigraphy and SPECT/CT fusion images were analyzed by two experienced nuclear medicine physicians together. Each patient was rated using a 3-point diagnostic confidence scale: metastasis, benign and uncertainty. The analyzed items were divided into two groups, i.e. certainty to diagnose (metastasis and benign) and uncertainty to diagnose. The percentage and its 95% confidence intervals of each group were calculated. The coincidence rate of bone metastases compared with the final diagnosis and its 95% confidence interval were calculated. The degree of certainty to diagnose on bone scintigraphy was 36.1% (35/97), its 95% confidence intervals range from 26.5% to 45.6%. The degree of uncertainty to diagnose on bone scintigraphy was 63.9% (62/97), its 95% confidence intervals range from 54.4% to 73.5%. The coincidence rate of bone metastases was 50.0% (24/48), its 95% confidence intervals range from 35.9% to 64.1%. The degree of certainty to diagnose on SPECT/CT fusion images was 81.4% (79/97), its 95% confidence intervals range from 73.7 % to 89.1%. The degree of uncertainty to diagnose on SPECT/CT fusion images was 18.6% (18/97), its 95% confidence intervals range from 10.9% to 26.3%. The coincidence rate of bone metastases was 95.8% (46/48), its 95% confidence intervals range from 90.1% to 100%. SPECT/CT fusion images provide more information than bone scintigraphy in differentiating metastases from benign lesions in patients with HCC, increase the degree of certainty to diagnose, especially increase the diagnostic accuracy in some false-negative cases diagnosed by bone scintigraphy.

    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

    The accuracy of bone metastases diagnostic coding based on International Classification of Diseases, ninth revision (ICD-9) is unknown for most large databases used for epidemiologic research in the US. Electronic health records (EHR) are the preferred source of data, but often clinically relevant data occur only as unstructured free text. We examined the validity of bone metastases ICD-9 coding in structured EHR and administrative claims relative to the complete (structured and unstructured) patient chart obtained through technology-enabled chart abstraction. Female patients with breast cancer with ≥1 visit after November 2010 were identified from three community oncology practices in the US. We calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of bone metastases ICD-9 code 198.5. The technology-enabled abstraction displays portions of the chart to clinically trained abstractors for targeted review, thereby maximizing efficiency. We evaluated effects of misclassification of patients developing skeletal complications or treated with bone-targeting agents (BTAs), and timing of BTA. Among 8,796 patients with breast cancer, 524 had confirmed bone metastases using chart abstraction. Sensitivity was 0.67 (95% confidence interval [CI] =0.63-0.71) based on structured EHR, and specificity was high at 0.98 (95% CI =0.98-0.99) with corresponding PPV of 0.71 (95% CI =0.67-0.75) and NPV of 0.98 (95% CI =0.98-0.98). From claims, sensitivity was 0.78 (95% CI =0.74-0.81), and specificity was 0.98 (95% CI =0.98-0.98) with PPV of 0.72 (95% CI =0.68-0.76) and NPV of 0.99 (95% CI =0.98-0.99). Structured data and claims missed 17% of bone metastases (89 of 524). False negatives were associated with measurable overestimation of the proportion treated with BTA or with a skeletal complication. Median date of diagnosis was delayed in structured data (32 days) and claims (43 days) compared with technology-assisted EHR. Technology

    Full Text Available Abstract Background A substantial number of breast cancer patients are identified as being at high risk of developing metastatic disease. With increasing number of targeted therapeutics entering clinical trials, chronic administration of these agents may be a feasible approach for the prevention of metastases within this subgroup of patients. In this preclinical study we examined whether Sunitinib, a multi-tyrosine kinase inhibitor which has anti-angiogenic and anti-resorptive activity, is effective in the prevention of bone metastases. Method Sunitinib was administered daily with the first dose commencing prior to tumor cell inoculation. Intracardiac injection was performed with MDA-MB23 bone-seeking cells, which were stably transfected with DsRed2. In vivo plain radiography and fluorescent imaging (Berthold NightOwl was used in the analysis of bone metastases. Histomorphometry was used for the quantification of TRAP+ cells from bone sections and immunohistochemistry was performed using an antibody reactive to CD34 for quantification of microvessel density. Results Preventive dosing administration of Sunitinib does not inhibit colonization of tumor cells to bone or reduce the size of osteolytic lesions. There was a decrease in the number of TRAP+ cells with Sunitinib treatment but this did not reach significance. Sunitinib inhibited tumor growth as determined by imaging of fluorescent tumor area. Immunohistochemical analyses of microvessel density revealed a concomitant decrease in the number of tumor blood vessels. Conclusions The findings suggest that Sunitinib can be used as a therapeutic agent for the treatment of bone metastases but as a single agent it is not effective in terms of prevention. Therefore a combination approach with other cytostatic drugs should be pursued.

    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.

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.

    Purpose Cabozantinib, an inhibitor of tyrosine kinases including MET, vascular endothelial growth factor receptors, and AXL, increased progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) in patients with advanced renal cell carcinoma (RCC) after previous vascular endothelial growth factor receptor-targeted therapy in the phase III METEOR trial. Because bone metastases are associated with increased morbidity in patients with RCC, bone-related outcomes were analyzed in METEOR. Patients and Methods Six hundred fifty-eight patients were randomly assigned 1:1 to receive 60 mg cabozantinib or 10 mg everolimus. Prespecified subgroup analyses of PFS, OS, and ORR were conducted in patients grouped by baseline bone metastases status per independent radiology committee (IRC). Additional end points included bone scan response per IRC, skeletal-related events, and changes in bone biomarkers. Results For patients with bone metastases at baseline (cabozantinib [n = 77]; everolimus [n = 65]), median PFS was 7.4 months for cabozantinib versus 2.7 months for everolimus (hazard ratio, 0.33 [95% CI, 0.21 to 0.51]). Median OS was also longer with cabozantinib (20.1 months v 12.1 months; hazard ratio, 0.54 [95% CI, 0.34 to 0.84]), and ORR per IRC was higher (17% v 0%). The rate of skeletal-related events was 23% with cabozantinib and 29% with everolimus, and bone scan response per IRC was 20% versus 10%, respectively. PFS, OS, and ORR were also improved with cabozantinib in patients without bone metastases. Changes in bone biomarkers were greater with cabozantinib than with everolimus. The overall safety profiles of cabozantinib and everolimus in patients with bone metastases were consistent with those observed in patients without bone metastases. Conclusion Cabozantinib treatment was associated with improved PFS, OS, and ORR when compared with everolimus treatment in patients with advanced RCC and bone metastases and represents a good treatment

    Purpose To determine the improvement of radiologist efficiency and performance in the detection of bone metastases at serial follow-up computed tomography (CT) by using a temporal subtraction (TS) technique based on an advanced nonrigid image registration algorithm. Materials and Methods This retrospective study was approved by the institutional review board, and informed consent was waived. CT image pairs (previous and current scans of the torso) in 60 patients with cancer (primary lesion location: prostate, n = 14; breast, n = 16; lung, n = 20; liver, n = 10) were included. These consisted of 30 positive cases with a total of 65 bone metastases depicted only on current images and confirmed by two radiologists who had access to additional imaging examinations and clinical courses and 30 matched negative control cases (no bone metastases). Previous CT images were semiautomatically registered to current CT images by the algorithm, and TS images were created. Seven radiologists independently interpreted CT image pairs to identify newly developed bone metastases without and with TS images with an interval of at least 30 days. Jackknife free-response receiver operating characteristics (JAFROC) analysis was conducted to assess observer performance. Reading time was recorded, and usefulness was evaluated with subjective scores of 1-5, with 5 being extremely useful and 1 being useless. Significance of these values was tested with the Wilcoxon signed-rank test. Results The subtraction images depicted various types of bone metastases (osteolytic, n = 28; osteoblastic, n = 26; mixed osteolytic and blastic, n = 11) as temporal changes. The average reading time was significantly reduced (384.3 vs 286.8 seconds; Wilcoxon signed rank test, P = .028). The average figure-of-merit value increased from 0.758 to 0.835; however, this difference was not significant (JAFROC analysis, P = .092). The subjective usefulness survey response showed a median score of 5 for use of the technique

    To study the role of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in monitoring the response of bone metastases to endocrine therapy combined with bisphosphonates in patients with breast cancer. Ten breast cancer patients with bone metastases who were to receive endocrine therapy and bisphosphonates were investigated prospectively by DCE-MRI. We chose a reference lesion for each patient who was studied at baseline, within 3 weeks from the second administration of bisphosphonates, and after 4 and 8 months from the initiation of medical treatment. Time/intensity curves, representing temporal changes of signal intensity in areas of interest in the context of the target lesions (ROI), were obtained for each DCE-MRI. Changes in the shape of the T/I curves suggesting tumor regression were seen shortly after the initiation of medical treatment in the three patients who had the most durable responses. DCE-MRI has the potential to detect early changes related to medical treatment in bone metastases from breast cancer. If confirmed in larger series, these data identify DCE-MRI as a diagnostic tool for evaluating new bone targeting antineoplastic agents.

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

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

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

    Full Text Available 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

    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

    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.

    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.

    Everolimus has shown to stop formation and activity of osteoclasts. Breast cancer patients with bone metastases only are candidates for effective but low toxic treatment. We evaluated everolimus in a double-blind, placebo-controlled, phase II, randomized discontinuation study in breast cancer patients with HER2 negative breast cancer patients with bone metastases only. After being stable on 8 weeks of everolimus 10 mg/day, patients were randomized to everolimus-continuation or placebo. Primary outcome was time (from randomization) to progression (TTP). Seventy-six patients would have had to be randomized to show a hazard ration (HR) of 0.5 for everolimus-continuation. Eighty-nine patients were enrolled in 4 years. Thirty-nine patients with SD after 8 weeks on everolimus were randomized to everolimus-continuation or placebo. TTP in patients with everolimus-continuation was 37.0 (95 % CI 16.7-40.3) versus 12.6 weeks (95 % CI 7.1-17.9) with placebo [HR 0.554 (95 % CI 0.282-1.09) p = 0.0818], adjusted for endocrine therapy [HR 0.464 (95 % CI 0.226-0.954) p = 0.037]. TTP in everolimus responders (n = 6) was 86 weeks. The RADAR study is mainly hypothesis generating. It suggests that everolimus has single-agent activity, and patients with bone metastases only may retrieve long-term benefit from everolimus if they do not progress within 8 weeks of treatment.

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

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

    Two new bisphosphonates have been examined for their ability to bind {sup 188}Re and deliver it selectively to bone. The bisphosphonates are prototype compounds with potential to deliver rhenium radionuclides and a second therapy modality to bone metastases. A conjugate between diethylenetriaminepentaacetic acid and bisphosphonate (DTPA/BP) and a conjugate between 5-fluorouracil and bisphosphonate (5-FU/BP) were prepared and labeled at high radiochemical purity with {sup 188}Re and biodistribution studies were carried out in normal Balb/C mice. The compounds showed rapid blood clearance and elimination from soft tissues with substantial retention of activity in the bone comparable to {sup 188}Re-hydroxyethylidine diphosphonate used as a control. At 8 h bone activity was 3.51% of injected dose for {sup 188}Re-DTPA/BP and 6.38% of injected dose for {sup 188}Re-5-FU/BP representing 69.6% and 80.6% of total body radioactivity, respectively. The two compounds show the potential for combination therapy of painful bone metastases.

    To compare the effects of resistance training versus passive physical therapy on bone density in the metastatic bone during radiation therapy (RT) as combined treatment in patients with spinal bone metastases. Secondly, to quantify pathological fractures after combined treatment. In this randomized trial, 60 patients were allocated from September 2011 until March 2013 into one of the two groups: resistance training (group A) or passive physical therapy (group B) with thirty patients in each group during RT. Bone density in metastatic and non-metastatic vertebral bone was assessed at baseline, 3 and 6 months after RT. Bone density in all metastases increased significantly by 28.3% (IQR 11.4-139.0) and 80.3% (IQR 32.6-250.6) after 3 and 6 months in group A (both p < 0.01). The bone density in group A was significantly increased compared to control group after 3 and 6months (both p < 0.01, median 59.7; IQR 21.1-98.3 and median 62.9; IQR -9.7 to 161.7). The bone density data in group B showed no significant increase over the course of time (p = 0.289, median 5.5, IQR 0.0-62.2 and p = 0.057, median 52.1, IQR 0.0-162.7). 23.3% of the patients in group A and 30.0% of the patients in group B had pathological fractures, no fracture was assigned to intervention, and no difference between groups after 3 and 6 months was observed (p = 0.592 and p = 0.604). Our trial demonstrated that resistance training concomitant to RT can improve bone density in spinal bone metastases. This combined treatment is effective, practicable, and without side effects for patients. Importantly, the pathological fracture rate in the intervention group was not increased. The results offer a rationale for future large controlled investigations to confirm these findings. Clinical trial identifier NCT01409720. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

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

    To evaluate the post-radiation lesions of the bone marrow with magnetic resonance imaging (MRI) and image analysis in patients with bone metastases undergoing radiation therapy (RT). Thirty-five patients with bone metastases were studied from June 2008 to December 2010. All patients had osseous metastases from various primary malignancies and underwent palliative RT. MRI was performed in a Philips Gyroscan Intera 1T scanner at the beginning of RT and 12-18 days later. T1-TSE, T2-TSE and short tau inversion recovery (STIR) sequences were used. All images obtained were evaluated for early post-radiation lesions. Additionally, 1st and 2nd order textural features were extracted from these images and were introduced into a probabilistic neural network (PNN) classifier in order to create an automated classification system for those lesions. Changes of signal intensity in T1-TSE, T2-TSE and STIR sequences were evaluated for the presence of edema, fatty conversion of the bone marrow or areas of hemorrhage within the limits of the irradiated area. The automated classification system showed positive results in correctly discriminating the post-radiation lesions that MRI revealed. The overall classification accuracy for discriminating between pre-radiation and post-radiation lesions was 93.2%. Furthermore, the overall classification accuracy for discriminating between post-radiation lesions was 86.67%. It seems that MRI can evaluate the degree of early therapy-induced bone marrow lesions observed during the first 18 days from the beginning of RT. The proposed neural network-based classification system might be used as an assisting tool for the characterization of these lesions.

    1,1-Bisphosphonates (BPs) are a family of compounds extensively used in the management of disorders of bone metabolism. 1 They accumulate in areas of high bone metabolism, such as bone metastases, and consequently have been receiving increasing attention as molecular imaging probes and pain palliation treatments. 2 Imaging bone metastases with BPs using single photon emission computed tomography (SPECT) or planar scintigraphy is one of the most often-performed clinical imaging procedures. Beta-emitting analogues capable of producing a therapeutic effect have also been developed. 3 In particular, the rhenium compounds 186/188 Re-hydroxyethylidene-1,1-diphosphonate ( 186/188 Re-HEDP) have shown promise as palliative agents for bone metastases in recent clinical trials. 4 The radiochemicals consist of a complex of a BP (e.g. methylene diphosphonate, MDP) with gamma- ( 99m Tc) or beta- ( 186/186 Re) emitters

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

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

    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

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

    To retrospectively assess the results of computed tomographic (CT) fluoroscopy-guided percutaneous osteoplasty (PO) of osteolytic lung cancer bone metastases, focusing on pain reduction, improved quality of life, and patient mobility. Over a 43-month interval, 92 patients with lung cancer bone metastases underwent PO, including vertebroplasty and acetabuloplasty. A total of 261 lesions of the vertebral column and 22 lesions of the pelvis, ilium, and femur were treated with the use of CT fluoroscopic guidance. Clinical outcomes were assessed, including pain, quality of life, and mobility, 24 hours before, 24 hours after, and 1 and 3 months after osteoplasty. Pain reduction and improved quality of life and patient mobility were observed in most patients. Visual analog scale and Karnofsky Performance Scale scores changed significantly (P < .05), from 6.1 ± 1.4 and 69.3 ± 5.5 at 24 hours before osteoplasty, respectively, to 3.5 ± 1.2 and 75.2 ± 5.4 at 24 hours after the procedure, 3.3 ± 1.2 and 76.5 ± 5.8 at 1 month, and 2.9 ± 1.5 and 79.6 ± 5.8 at 3 months after PO. Mobility scale score, Frankel classification of spinal cord injury, and Harris hip score also changed significantly (P < .05) after osteoplasty. No major complications occurred. PO was shown to be a highly effective and safe palliative therapy to reduce pain and improve quality of life and patient mobility, not only in vertebral metastases, but also in pelvic, iliac, and femoral metastases.

    785 combined diagnostic procedures are reported which were carried out on 353 patients with microscopically proven carcinoma of the prostate in order to detect metastases. X-ray films of the thorax, spine and pelvis were taken. Also bone-scintigraphy was done with 87MSr or 99MTc-polyphosphate. Additionally the alcaline, acid and prostate phosphatases were determined. A diagnostic coincidence between radiological results and bone-scan was found in 95.1% of cases. The bone-scan was false negative in 3.7%. Only in 1.2% metastases were detected earlier by the bone-scan than by x-ray examinations. Referring to the number of studies identical results were found. In roentgenologically detected metastases an increased serum level of the alcaline phosphatase was found in 61%, of the acid phosphatase in 31% and of the prostate-phosphatase in 25%.

    Magnetic resonance imaging (MRI) and single-photon emission computerised tomography/computerised tomography (SPECT/CT) are used as diagnostic tools in symptomatic patients after reconstruction of the anterior cruciate ligament (ACL). The benefit of SPECT/CT in comparison with MRI is under debate. The purpose of this study was to investigate whether and how bone tracer uptake (BTU) intensity and distribution in SPECT/CT correlate with MRI findings in symptomatic patients after ACL reconstruction. Twenty-nine patients (male:female = 22:7, mean age ± SD 26 ± 10 years) with symptoms of pain and instability after ACL reconstruction were retrospectively investigated using prospectively acquired SPECT/CT and MRI. On MRI graft tear, graft signal intensity, bone marrow oedema, tunnel cyst formation, roof impingement, roof osteophytes, local arthrofibrosis, joint effusion and synovial thickness were analysed by two readers blinded to the BTU results. BTU was anatomically localised and volumetrically quantified. Spearman's rho test was used for correlation of BTU in SPECT/CT and MRI findings (p tracer uptake in SPECT/CT and defined MRI findings in symptomatic patients after ACL reconstruction were correlated. Both imaging modalities have a definite role in post-operative diagnostic and have established their value in those patients. This study provides a better understanding of the clinical value of SPECT/CT versus MRI in the clinical decision-making process. SPECT/CT provides a window into the in vivo loading of the joint as well as bone remodelling and graft incorporation process. In addition, ACL graft insufficiency can be detected by increased BTU.

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

    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.

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

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

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

    Mostly radionuclide therapy was used as a sole method in clinical practice and seldom combined with chemotherapy, immunotherapy or radiotherapy as a treatment procotol. Pain palliation of bone metastases has become a main field in radionuclide therapy in the recent years and strontium-89 is a main radionuclide clinical used. Combining with chemotherapy, doxorubicin, gemcitabin, cisplatin, and radiotherapy can enhance the affect of radionuclide therapy and prolong the period of pain palliation. This concomitant method was used in the treatment of lymphoma, neuroblastoma and glioma and showed excellent prospect. (authors)

    Purpose To determine the usefulness of whole-body diffusion-weighted imaging (DWI) to assess the response of bone metastases to treatment in patients with metastatic castration-resistant prostate cancer (mCRPC). Materials and Methods A phase II prospective clinical trial of the poly-(adenosine diphosphate-ribose) polymerase inhibitor olaparib in mCRPC included a prospective magnetic resonance (MR) imaging substudy; the study was approved by the institutional research board, and written informed consent was obtained. Whole-body DWI was performed at baseline and after 12 weeks of olaparib administration by using 1.5-T MR imaging. Areas of abnormal signal intensity on DWI images in keeping with bone metastases were delineated to derive total diffusion volume (tDV); five target lesions were also evaluated. Associations of changes in volume of bone metastases and median apparent diffusion coefficient (ADC) with response to treatment were assessed by using the Mann-Whitney test and logistic regression; correlation with prostate-specific antigen level and circulating tumor cell count were assessed by using Spearman correlation (r). Results Twenty-one patients were included. All six responders to olaparib showed a decrease in tDV, while no decrease was observed in all nonresponders; this difference between responders and nonresponders was significant (P = .001). Increases in median ADC were associated with increased odds of response (odds ratio, 1.08; 95% confidence interval [CI]: 1.00, 1.15; P = .04). A positive association was detected between changes in tDV and best percentage change in prostate-specific antigen level and circulating tumor cell count (r = 0.63 [95% CI: 0.27, 0.83] and r = 0.77 [95% CI: 0.51, 0.90], respectively). When assessing five target lesions, decreases in volume were associated with response (odds ratio for volume increase, 0.89; 95% CI: 0.80, 0.99; P = .037). Conclusion This pilot study showed that decreases in volume and increases in median ADC

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

    Full text: It is estimated that approximately two-thirds of the patients with advanced malignancy experience substantial pain. Alleviation of bone pain in such patients may be achieved with narcotic and non-narcotic analgesics, surgery, radiotherapy and hormonal agents. Nowadays radionuclide treatment is accepted as a systemic and specific treatment in patients with intractable bone pain. The aim of the study was to share our first experience with application of Sr-89 chloride and to compare the results with P-32 orthophosphate therapy in patients with painful bone metastases. A total of 24 patients (group-I), 11 of breast cancer, 10 of prostate cancer and 3 of other type of cancers were treated with Sr-89. 114 patients (group-II), 93 of breast cancer and 21 of prostate cancer were treated with P-32. Sr-89 (Amersham Health) was administered intravenously in a dose of 148 MBq while P-32 (Polatom- Poland) was given orally in activities starting from 37 MBq increased up to total dose of 222 MBq at 30-60 days intervals. Efficacy of the treatment was evaluated on the basis of pain score and frequency and quality of analgesic medication, Karnovsky index and findings of bone scan. A symptomatic reduction of the pain was achieved in 17 (72%) of the group-I patients while 28% showed full response with Sr-89. From group-II treated with P-32, 78% showed partial and 10% full response. Adverse effects noticed in group-I were reduction of platelet and leukocyte counts in 18% and 19% respectively while in group-II the same was noticed in 20% and 30% of patients respectively. In most of the patients, bone marrow toxicity observed in the first month following treatment recovered shortly in both the groups. None of the patient required blood transfusion. The duration of the response was 3.3 months (10 days to 9 months) in group-I and 3.4 months (7 days to 7 months) in group- II patients. Two patients from group-II had a short lasting nephro-toxicity.

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

    A 73-year-old man, followed for prostatic hyperplasia, developed submandibular gland cancer. Initially, because of the concurrent presence of elevated serum prostate-specific antigen (PSA) and multiple bone metastases, he was clinically determined as having stage IV prostate cancer in addition to stage II submandibular gland cancer, and radical surgery for his submandibular gland cancer was performed first. However, subsequent detailed examinations of the prostate gland showed no prostate cancer, and a diagnosis of advanced submandibular gland cancer with increased PSA and multiple bone metastases was established. Serum PSA is highly specific for prostate diseases and is widely used as a tumor marker of prostate cancer. However, clinicians should be aware that, in patients with non-prostate cancer, the detection of increased PSA and multiple bone metastases does not necessarily indicate the concurrent presence of prostate cancer.

    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.

    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

    Due to the fact that fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) and technetium-99m-methylenediphosphonate ((99m)Tc-MDP) whole body scans identify bone metastases by different mechanisms, i.e. by using glucose metabolism and osteoblastic response in the bone, respectively, it can be expected that there may be some differences between these two methods in the number of lesions identified. The aim of this study was to compare the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) in detecting bone metastases between (18)F-FDG-PET/CT and conventional (99m)Tc-MDP whole body scans. Between 2006-2009, 121 patients with malignancies (62 male and 59 female, mean age 59.3±10.8 years, range 37-84) were examined with (18)F-FDG-PET/CT and conventional (99)Tc-MDP whole-body scans for detection of bone metastases. For (18)F-FDG-PET/CT and for (99m)TC-MDP, sensitivity, specificity, accuracy, PPV and NPV for detecting all studied bone metastases were 88.3, 83.6, 86.7, 91.7, 77.8% and 91.7, 71.0, 84.9, 86.6, 80.8%, respectively. For bone metastases of breast and lung cancers, the specificity and accuracy of PET/CT was higher than that of bone scintigraphy. On the other hand, the sensitivity of bone scintigraphy was higher than PET/CT in breast and lung cancers groups and all patients. In the detection of osteolytic and osteosclerotic metastases no difference was found between the two methods, while for osteolytic lesions the mean standardized uptake value (SUV) max was higher than for osteosclerotic lesions. For the detection of bone metastases the specificity and accuracy of (18)F-FDG-PET/CT were higher compared to bone scintigraphy, while the sensitivity was lower. It is the opinion of the authors that both studies are complementary to final diagnosis.

    The objective of this study was to evaluate the feasibility and diagnostic value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-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 18F-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 18F-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. 18F-FDG PET/CT achieved higher sensitivity, specificity, and accuracy in detecting osteolytic bone metastases than 99mTc-MDP whole-body BS (pMDP whole-body BS in the detection of osteolytic bone metastases, especially in the vertebra.

    Recombinant human bone morphogenetic protein-2 (rhBMP-2) has been approved for use in the lumbar spine in conjunction with the lumbar tapered cage. However, off-label use of this osteoinductive agent is observed with anterior fusion applications as well as with both posterior lumbar interbody fusion and transforaminal lumbar interbody fusion (TLIF). Complications using rhBMP-2 in the cervical spine have been reported. Although radiographic evidence of ectopic bone in the lumbar spine has been described following rhBMP-2 use, this finding was not previously believed to be of clinical relevance. This study was a retrospective review of 4 patients who underwent minimally invasive spinal TLIF (MIS-TLIF) in which bone fusion was augmented with rhBMP-2 applied to an absorbable collagen sponge. Case presentations, operative findings, imaging data, and follow-up findings were reviewed. Four cases with delayed symptomatic neural compression following the off-label use of rhBMP-2 with MIS-TLIF were identified. Although previously believed to be only a radiographic finding, the development of ectopic bone following rhBMP-2 use in lumbar fusion can be clinically significant. This paper describes 4 cases of delayed neural compression following MIS-TLIF. The reader should be aware of this potential complication following the off-label use of rhBMP-2 in the lumbar spine.

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

    To compare the value of prostatic specific antigen (PSA) with bone scan results, a study was conducted enrolling 25 prostatic adenocarcinoma patients, fulfilling the following criteria for inclusion: a) histological confirmation of diagnosis b) radical prostatectomy at least three months before bone scan as curative therapy c) at least one month between bone scan and PSA measurement. Fourteen cases were within normal ranges on both techniques. Eleven had metastases on bone scans, with PSA in normal range in five of them. The Spearman's ranks coefficient was rs=0,92, with alfa=0,01, accepting that both tecniques are comparable. (Authors). 10 refs., 1 tab., 2 figs

    To obtain the necessary acquisition and calibration parameters in order to evaluate the possibility of detecting and quantifying 223 Ra uptake in bone metastases of patients treated for castration resistant prostate carcinoma. Furthermore, in the cases in which the activity can be quantified, to determine the absorbed dose. Acquisitions from a Petri dish filled with 223 Ra were performed in the gamma camera. Monte Carlo simulations were also performed to study the partial volume effect. Formulae to obtain the detection and quantification limits of 223 Ra uptake were applied to planar images of two patients 7 days post-administration of 55kBq/kg of 223 Ra. In order to locate the lesions in advance, whole-body scans and SPECT/CT images were acquired after injecting 99m Tc-HDP. The optimal energy window was found to be at 82keV with a medium-energy collimator MEGP. Of the lesions found in the patients, only those that had been detected in both the AP and PA projections could be quantified. These lesions were those which had shown a higher 99m Tc-HDP uptake. The estimated values of absorbed doses ranged between 0.7Gy and 7.8Gy. Of the lesions that can be detected, it is not possible to quantify the activity uptake in some of them, which means that the absorbed dose cannot be determined either. This does not mean that the absorbed dose in these lesions can be regarded as negligible. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

    Full Text Available Abstract Background To assess prognostic and predictive effects of clinical and biochemical factors in our published randomized study of a weekly low dose (metronomic arm versus a conventional dosage of zoledronic acid (conventional arm in breast cancer patients with bone metastases. Methods Treatment outcome of 60 patients with bone metastases were used to assess impacts of following potential prognostic factors, estrogen receptor status, lymph node status, 2 year-disease free interval (DFI, numbers of chemotherapy regimens administered, interventions, and serum levels of VEGF, N-telopeptide of type I collagen (NTx, CEA, and CA 15-3. Results In univariate analyses, patients pretreated with 2 or fewer chemotherapy regimens, ER-positive tumors, 3 or fewer lymph nodes, DFI of more than 2 years, serum VEGF of less than 500 pg/mL after 3 months of intervention, serum CEA and CA 15-3 of less than ULN, and baseline serum NTx of less than 18 nM BCE had significantly longer progression free survival (PFS. The multivariate analysis showed that ER positivity (hazard ratio [HR], 0.295; 95% confidence interval [CI], 0.141-0.618; P = 0.001, serum VEGF of less than 500 pg/mL after 3 months of intervention (HR, 2.220; 95% CI, 1.136-4.338; P = 0.020, baseline serum NTx of less than 18 nM BCE (HR, 2.842; 95% CI, 1.458-5.539; P = 0.001, and 2 or fewer chemotherapy regimens received (HR, 7.803; 95% CI, 2.884-21.112; P = 0.000 were associated with a better PFS. When evaluating the predictive effect of the biochemical factors, an interaction between NTx and zoledronic acid intervention was shown (P = 0.005. The HR of weekly low dose versus a conventional dosage of zoledronic acid was estimated to be 2.309 (99% CI, 1.067-5.012 in patients with baseline serum NTx of more than 18 nM BCE, indicating a superiority of weekly low dose of zoledronic acid. Conclusions ER, serum VEGF level after intervention, and numbers of chemotherapy regimens administered are prognostic

    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.

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

The level of QoL is related to the actual survival, with a rather stable course of QoL for most of the remaining survival time and afterward a sharp decrease, starting only a few weeks before the end of life. Six fractions of 4 Gy lead to a temporary worse physical QoL compared with a single fraction of 8 Gy.

    Diffusion-weighted imaging quantified using the mono-exponential model has shown great promise for monitoring treatment response in prostate cancer bone metastases. The aim of this prospective study is to evaluate whether non-mono-exponential diffusion models better describe the water diffusion properties and may improve treatment response assessment. Diffusion-weighted imaging data of 12 treatment-naïve patients with 34 metastases acquired before and at one, two, and three months after initiation of antiandrogen treatment are analysed using the mono-exponential, the intravoxel incoherent motion, the stretched exponential, and the statistical model. Repeatability of the fitted parameters and changes under therapy are quantified. Model preference is assessed and correlation coefficients across times are calculated to delineate the relationship between the prostate-specific antigen levels and the diffusion parameters as well as between the diffusion parameters within each model. There is a clear preference for non-mono-exponential diffusion models at all time points. Particularly the stretched exponential is favoured in approximately 60% of the lesions. Its parameters increase significantly in response to treatment and are highly repeatable. Thus, the stretched exponential may be utilized as a potential optimal model for monitoring treatment response. Compared with the mono-exponential model, it may provide complementary information on tissue properties and improve response assessment.

    The diagnostic value of whole body scanning using {sup 99m}Tc-N-pyridoxylmethyltryptophan (PMT) was evaluated in 16 patients with bone metastases from hepatocellular carcinoma, in combination with {sup 99m}Tc-MDP. Of the 72 known lesions of bone metastases, 63 (87.5%) were detected by {sup 99m}Tc-PMT scintigraphy, which demonstrated increased uptake of radionuclide. However, {sup 99m}Tc-MDP bone scintigraphy detected only 45 lesions (62.5%), which were shown as increased, decreased, or mixed patterns of uptake. Thus {sup 99m}Tc-PMT scintigraphy was more sensitive than {sup 99m}Tc-MDP bone scintigraphy. In addition, the latter showed poor specificity because of its high false positive rate due to degenerative change. All lesions undetected by {sup 99m}Tc-PMT scintigraphy were located in areas that overlapped the liver or bowel activity. In conclusion, it is recommended that whole body {sup 99m}Tc-PMT scintigraphy be combined with {sup 99m}Tc-MDP bone scintigraphy for the detection of bone metastases from hepatocellular carcinoma.

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

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

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

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

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

    The skeletal 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

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

    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.

    The purpose of this study was to compare, retrospectively, the detection of bone metastases in patients with breast cancer by means of [18F]-FDG PET and bone scintigraphy using [{sup 99m}Tc]-HMDP. Twenty three patients with known breast cancer were examined with both methods within 2 months (mean 22 days). The findings were correlated in 20 patients with other imaging modalities including computed tomography (CT), magnetic resonance imaging (MRI), standards X-rays and, in unclear circumstances, with clinical and imaging follow up examinations over 6 months. We found that the sensitivity, specificity and accuracy of FDG-PET were respectively 86%, 100% and 94% and were for bone scintigraphy 100%, 77% and 85%. In conclusion, our findings suggest that [18F]--FDG PET was superior to bone scintigraphy in its specificity and accuracy for detecting bone metastases in patients with breast cancer, in concordance with the others studies in the literature.

    Full Text Available Patients with solid cancer frequently develop bone metastases (BM. Zoledronic acid (Zometa®, ZA, routinely used to treat patients with BM, acts on osteoclasts and also has antitumor properties. We aimed to assess the effect of ZA over time in novel bone turnover markers (RANK/receptor activator of nuclear factor-k B ligand (RANK-L/ Osteoprotegerin (OPG and to correlate these with serum N-terminal telopeptide (NTX. The study prospectively evaluated levels of RANK, RANK-L and OPG transcripts by real-time PCR and NTX expression by ELISA in the peripheral blood of 49 consecutive patients with advanced breast, lung or prostate cancer. All patients received the standard ZA schedule and were monitored for 12 months. Median baseline values of RANK, RANK-L and OPG were 78.28 (range 7.34–620.64, 319.06 (21.42–1884.41 and 1.52 (0.10–58.02, respectively. At 12 months, the median RANK-L value had decreased by 22% with respect to the baseline, whereas median OPG levels had increased by about 96%. Consequently, the RANK-L/OPG ratio decreased by 56% from the baseline. Median serum NTX levels decreased over the 12-month period, reaching statistical significance (p < 0.0001. Our results would seem to indicate that ZA modulates RANK, RANK-L and OPG expression, thus decreasing osteoclast activity.

    Background and purpose: The aim of this study was to compare the need for re-irradiation, rates of pathological fractures, and spinal cord compressions in patients randomised to single-fraction radiotherapy (8 Gy x 1) or multiple-fraction therapy (3 Gy x 10) and with a long-term follow-up. The underlying hypothesis was that single-fraction and multiple-fraction regimens are equally effective. Material and methods: The present study reports on the Norwegian sub sample of an international large prospective-randomised multicentre study. One hundred and eighty patients with painful skeletal metastases in four Norwegian hospitals were randomised to receive single-fraction (8 Gy x 1) or multiple-fraction (3 Gy x 10) radiotherapy. Results: Patients in the single-fraction arm received significantly more re-irradiations as compared to the multiple-fraction arm (27% versus 9%, p = 0.002). There were no significant differences in the rate of pathological fractures (5% versus 5%, p = 1.00) or spinal cord compressions (1% versus 4%, p = 0.37) between the two treatment groups. Conclusion: The present study indicates no difference between radiotherapy with 8 Gy x 1 and 3 Gy x 10 for the majority of patients with painful bone metastases, also in a long-term perspective. Importantly, the patients in this study were followed up until death, and the trial showed no disadvantage for 8 Gy x 1 compared to 3 Gy x 10. Despite the fact that single-fraction treatment will imply an approximately 2.5-fold greater need for re-irradiation, single-fraction treatment is considered more convenient for the patients and more cost-effective for the radiotherapy departments.

    Only few procedures for Lisfranc ligaments reconstruction to treat subtle injury of the Lisfranc joint have been reported. We have developed a novel technique for Lisfranc ligaments reconstruction, which was applied to treat chronic symptomatic subtle injuries that had failed to respond to initial treatment or were misdiagnosed. This article describes the technique and its operative outcome in a small case series. Between April 2011 and October 2013, 5 (4 male and 1 female) athletes with a mean age of 19.4 (range 17-21) years were diagnosed with chronic subtle injury of the Lisfranc joint and underwent our novel reconstructive operation. In this technique, only a bone tunnel between the medial cuneiform and the second metatarsal bone is needed for near-anatomical reconstruction of the dorsal and interosseous ligaments. All patients were evaluated before and at 1 year after surgery using the American Orthopaedic Foot and Ankle Society (AOFAS) scale for the ankle-midfoot. In addition, the interval between surgery and return to athletic activity, defined as return to near pre-injury performance level, was investigated. Mean duration of postoperative follow-up was 18.8 (range 12-26) months. Mean AOFAS score improved significantly from 74.6 ± 2.5 (range 71-77) preoperatively to 96.0 ± 5.5 (range 90-100) at 1 year after the operation (p athletic activities and the interval between surgery and return to athletic activity was 16.8 ± 1.1 (range 15-18) weeks. There was no complication related to the operation. The results of this study suggest that our technique of Lisfranc ligaments reconstruction using autologous graft is effective for athletes with chronic subtle injury.

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

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

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

    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).

    Bisphosphonates have effects that are antiresorptive, antitumor, and antiapoptotic to osteoblasts and osteocytes, but an effective means of eliciting these multiple activities in the treatment of bone metastases has not been identified. Antimetabolite-bisphosphonate conjugates have potential for improved performance as a class of bone-specific antineoplastic drugs. The primary objective of the study was to determine whether an antimetabolite-bisphosphonate conjugate will preserve bone formation concomitant with antiresorptive and antitumor activity. 5-FdU-ale, a highly stable conjugate between the antimetabolite 5-fluoro-2'-deoxyuridine and the bisphosphonate alendronate, was tested for its therapeutic efficacy in a mouse model of MDA-MB231 breast cancer bone metastases. In vitro testing revealed osteoclasts to be highly sensitive to 5-FdU-ale. In contrast, osteoblasts had significantly reduced sensitivity. Tumor cells were resistant in vitro but in vivo tumor burden was nevertheless significantly reduced compared with untreated mice. Sensitivity to 5-FdU-ale was not mediated through inhibition of farnesyl diphosphate synthase activity, but cell cycle arrest was observed. Although serum tartrate-resistant acid phosphatase (TRAP) levels were greatly reduced by both drugs, there was no significant decrease in the serum bone formation marker osteocalcin with 5-FdU-ale treatment. In contrast, there was more than a fivefold decrease in serum osteocalcin levels with alendronate treatment (p bisphosphonates offers flexibility in creating potent bone-targeting drugs with cytostatic, bone protection properties that show limited nephrotoxicity. This unique class of drugs may offer distinct advantages in the setting of targeted adjuvant therapy and chemoprevention of bone diseases. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

    A 73-year-old man, followed for prostatic hyperplasia, developed submandibular gland cancer. Initially, because of the concurrent presence of elevated serum prostate-specific antigen (PSA) and multiple bone metastases, he was clinically determined as having stage IV prostate cancer in addition to stage II submandibular gland cancer, and radical surgery for his submandibular gland cancer was performed first. However, subsequent detailed examinations of the prostate gland showed no prostate can...

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

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

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

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

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

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

    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.

    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.

    The aim of this study was to compare (18)F-fluoride PET/CT and (99m)Tc-MDP bone scintigraphy in the detection of skeletal metastases in urinary bladder carcinoma. In this prospective study, 48 patients with urinary bladder carcinoma (44 male and 4 female patients, aged 35-80 years) underwent (99m)Tc-MDP planar and SPECT/CT bone scan (BS) followed by (18)F-fluoride PET/CT within 48 hours. Skeletal metastasis diagnosed on each of these techniques was compared against a final diagnosis based on contrast-enhanced CT, MRI, skeletal survey, clinical follow-up, and histological correlation. (18)F-fluoride PET/CT identified bony metastases and changed the management in 17 of 48 patients (35%). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of (99m)Tc-MDP planar BS were 82.35%, 64.51%, 56%, 86.95%, and 70.83%; of (99m)Tc-MDP SPECT/CT were 88.23%, 74.19%, 65.21%, 92%, and 79.16%; and of (18)F-fluoride PET/CT were 100%, 87.09%, 80.95%, 100%, and 91.66%, respectively. Fair agreement between (99m)Tc-MDP planar BS and F-fluoride PET/CT (κ = 0.42) and excellent agreement between SPECT/CT and (18)F-fluoride PET/CT (κ = 0.74) were found. ( 18)F-fluoride PET/CT has higher sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in detecting bone metastases in urinary bladder carcinoma than conventional (99m)Tc-MDP planar BS. SPECT/CT improves all these parameters compared with planar BS and may serve as a cost-effective screening procedure for the detection of skeletal metastases in high-risk patients.

    Full Text Available Small cell carcinoma (SmCC of the prostate is a very rare and aggressive type of prostatic cancer. It is hard to early diagnose and most cases are diagnosed at advanced stage. The bones, liver, regional and distant lymph nodes are the most common sites of metastasis. The treatment for SmCC of the prostate is different from that of acinar adenocarcinoma. While chemotherapy is suggested, there is no standard regimen, let alone personalized strategy. Additionally, hormone therapy does not often work for this type of prostate cancer. Here, we report a rare case of SmCC of the prostate who initially presented with lower cervical spine radiculopathy.

    Bisphosphonates (BPs) are often used for the treatment of several diseases such as osteoporosis, cancer-associated hypercalcemia, and osteolytic bone metastasis. Recently, there have been reports of osteonecrosis of the jaw (ONJ) in cancer patients whose treatment regimens include BPs. In this case report, we describe complications and treatment of ONJ in a breast cancer patient with bone metastases who received long-term treatment with BPs. A 70-year-old woman underwent modified radical mastectomy on her left breast cancer and received oral 5-fluorouracil derivatives for 2 years in another hospital. Eleven years after the surgery, she came to our hospital complaining of spinalgia and was diagnosed with recurrent breast cancer with multiple metastases to the stomach, liver, multiple lymph nodes, and spine. After surgery for spine metastases, she was given a combination therapy of trastuzumab (initial bolus: 170 mg/body, followed by two or more cycles of 85 mg/body) every week, docetaxel (100 mg/body) every 3 weeks, and BPs (90 mg/body) every 4 weeks. About 1 year and 4 months later, she complained of pain in her right maxilla; biopsy revealed ONJ. Medical oncologists need to recognize ONJ as a serious side effect of BP treatment; dentists and oral and maxillofacial surgeons need to thoroughly consult patients regarding the administration of BPs and have them make an informed consent.

    Purpose: To evaluate local transarterial chemoperfusion (TACP) of therapy-resistant, locally recurrent malignant tumors and lymph node metastases in the pelvis with respect to clinical response, tumor response and survival. Materials and methods: Between 2003 and 2005, 24 outpatients (median age 56.5 years, range 33 - 82) were treated with 128 TACPs (min. 3; mean 5 sess/patient) in 4-week intervals. Depending on the tumor location and vascularization, a fluoroscopy catheter was placed either in the abdominal aorta or internal pelvic artery. A combination of mitomycin C (6 mg/m{sup 2}) and gemcitabine (1500 mg/m{sup 2}) was administered over 60 minutes. The tumor size was measured using CT or MRI. The radiological response was classified according to RECIST (Response Evaluation Criteria In Solid Tumors) as 'complete response' (CR), 'partial response' (PR), 'stable disease' (SD) and 'progressive disease' (PD). The clinical response was classified as 'response{sub clinical}' if the symptoms improved distinctly, 'stable disease{sub clinical}' if complaints were stabilized, and 'progression{sub clinical}' if symptoms deteriorated or new symptoms appeared. After the third TACP, patients were evaluated for clinical and radiological response. In the case of clinical and radiological progression, therapy was stopped and the patient was referred to the hospital's tumor board. In the case of radiological response and clinical progression or clinical response and radiological progression, therapy was continued. Therapy could be stopped by the patient at any time. Results: Treatment was tolerated well by all patients. No clinically relevant problems and no grade III or IV toxicity according to CTC (Common Toxicity Criteria) appeared. Tumor-related pain, bleeding, restricted mobility of the lower extremities, incontinence, urinary tract obstruction, and constipation were reduced in 9/17, 5/6, 3/3, 1/3, 2

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

    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.

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

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

    We aimed to compare the role of (18)F-fluoride PET/CT, FDG PET/CT and (99m)Tc-MDP bone scans in the detection of bone metastases in patients with lung, breast and prostate carcinoma. This was a prospective study including patients for staging (S) and restaging (R). Seventy-two patients (23S, 49R) with infiltrating ductal breast carcinoma, 49 patients (25S, 24R) with prostate adenocarcinoma and 30 patients (17S, 13R) with non-small-cell lung carcinoma (NSCLC), without known bone metastases but with high risk/clinical suspicion for the same, underwent a (99m)Tc-MDP bone scan, FDG PET/CT and (18)F-fluoride PET/CT within 2 weeks. All scans were reviewed by two experienced nuclear medicine physicians, and the findings were correlated with MRI/thin-slice CT/skeletal survey. Histological verification was done wherever feasible. Sensitivity and negative predictive value (NPV) of (18)F-fluoride PET/CT was 100 % in all three malignancies, while that of FDG PET/CT was 79 % and 73 % in NSCLC, 73 % and 80 % in breast cancer and 72 and 65 % in prostate cancer. Specificity and positive predictive value (PPV) of FDG PET/CT were 100 % in NSCLC and prostate and 97 % and 96 % in breast cancer. As compared to the (99m)Tc-MDP bone scan, all parameters were superior for (18)F-fluoride PET/CT in prostate and breast cancer, but sensitivity and NPV were equal in NSCLC. The MDP bone scan had superior sensitivity and NPV compared to FDG PET/CT but had low specificity and PPV. To rule out bone metastases in cases where there is a high index of suspicion, (18)F-fluoride PET/CT is the most reliable investigation. (18)F-fluoride PET/CT has the potential to replace the (99m)Tc-MDP bone scan for the detection of bone metastases.

    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

    2017-01-01

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

    To explore the age difference in response and patient-reported outcomes in patients with cancer having bone metastases undergoing palliative radiotherapy. Patients completed the European Organisation for Research and Treatment of Cancer (EORTC) Quality-of-Life (QOL) Bone Metastases module (QLQ-BM22), EORTC QOL Core-15-Palliative (QLQ-C15-PAL), and Dexamethasone Symptom Questionnaire (DSQ) before a single 8-Gy radiation treatment, on days 10 and 42 after treatment. Patient demographics, performance status, analgesic consumption, BM22, C15, and DSQ were compared with multivariant analysis between patients under 75 years and 75 years and older. Multiple linear regression models were used to assess the differences between age-groups, adjusting for baseline demographics and primary disease sites. There were 298 patients (170 male) with 209 (70%) less than 75 years of age. Most common primary cancer sites include lung, prostate, and breast. At baseline, younger patients had better performance status, consumed more analgesic, and reported worse scores in nausea, insomnia, and functional interference, while older patients more commonly had prostate cancer. There were no significant differences in the incidence of radiation-induced pain flare; response to radiation; changes from baseline for BM22, C15-PAL; and DSQ, nor overall survival at day 42 between the 2 groups. Responders to radiation in the elderly group reported better improvement in physical and emotional domains when compared with nonresponders. In patients with cancer having bone metastases undergoing palliative radiotherapy, there was no significant difference in general with age in response to radiation and patient-reported outcomes. Palliative radiotherapy should be offered to elderly patients when needed.

    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

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

    We prospectively evaluated and compared the diagnostic performance of 99m Tc-hydroxyethylene-diphosphonate ( 99m Tc-HDP) planar bone scintigraphy (pBS), 99m Tc-HDP SPECT/CT, 18 F-NaF PET/CT, and 18 F-NaF PET/MRI for the detection of bone metastases. Methods: One hundred seventeen patients with histologically proven malignancy referred for clinical pBS were prospectively enrolled. pBS and whole-body SPECT/CT were performed followed by 18 F-NaF PET/CT within 9 d. 18 F-NaF PET/MRI was also performed in 46 patients. Results: Bone metastases were confirmed in 16 patients and excluded in 101, which was lower than expected. The number of equivocal scans was significantly higher for pBS than for SPECT/CT and PET/CT (18 vs. 5 and 6, respectively; P = 0.004 and 0.01, respectively). When equivocal readings were excluded, no statistically significant difference in sensitivity, specificity, positive predictive value, negative predictive value, or overall accuracy were found when comparing the different imaging techniques. In the per-patient analysis, equivocal scans were either assumed positive for metastases ("pessimistic analysis") or assumed negative for metastases ("optimistic analysis"). The percentages of misdiagnosed patients for the pessimistic analysis were 21%, 15%, 9%, and 7% for pBS, SPECT/CT, PET/CT, and PET/MRI, respectively. Corresponding figures for the optimistic analysis were 9%, 12%, 5%, and 7%. In those patients identified as having bone metastases according to the reference standard, SPECT/CT, 18 F-NaF PET/CT, and PET/MRI detected additional lesions compared with pBS in 31%, 63%, and 71%, respectively. Conclusion: 18 F-NaF PET/CT and whole-body SPECT/CT resulted in a significant reduction of equivocal readings compared with pBS, which implies an improved diagnostic confidence. However, the clinical benefit of using, for example, 18 F-NaF PET/CT or PET/MRI as compared with SPECT/CT and pBS in this patient population with a relatively low prevalence of bone

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

    Blood-spinal cord barrier (BSCB) alterations, including capillary rupture, have been demonstrated in animal models of amyotrophic lateral sclerosis (ALS) and ALS patients. To date, treatment to restore BSCB in ALS is underexplored. Here, we evaluated whether intravenous transplantation of human bone marrow CD34+ (hBM34+) cells into symptomatic ALS mice leads to restoration of capillary integrity in the spinal cord as determined by detection of microhemorrhages. Three different doses of hBM34+ cells (5 × 104, 5 × 105 or 1 × 106) or media were intravenously injected into symptomatic G93A SOD1 mice at 13 weeks of age. Microhemorrhages were determined in the cervical and lumbar spinal cords of mice at 4 weeks post-treatment, as revealed by Perls’ Prussian blue staining for ferric iron. Numerous microhemorrhages were observed in the gray and white matter of the spinal cords in media-treated mice, with a greater number of capillary ruptures within the ventral horn of both segments. In cell-treated mice, microhemorrhage numbers in the cervical and lumbar spinal cords were inversely related to administered cell doses. In particular, the pervasive microvascular ruptures determined in the spinal cords in late symptomatic ALS mice were significantly decreased by the highest cell dose, suggestive of BSCB repair by grafted hBM34+ cells. The study results provide translational outcomes supporting transplantation of hBM34+ cells at an optimal dose as a potential therapeutic strategy for BSCB repair in ALS patients. PMID:29535831

    To evaluate the detection rate of bone metastases obtained with the PSMA targeting tracer 99m Tc-MIP-1427 as opposed to the conventional bone scan with 99m Tc-MDP in a collective of advanced stage patients with known osseous metastasized prostate cancer. Methods: 21 Patients with known metastatic disease were staged with both, conventional bone scan and PSMA-ligand scintigraphy, within a time-frame of MDP. Lesions were scored: typical tumor, equivocal (benign/malignant), or normal within a standard reporting schema divided into defined anatomical regions. Blind and consensus reads were performed with sequential un-blinding: first planar scans, then SPECT/CT, then best valuable comparator including MRI, PET/CT and follow-up exams. Results: 11 patients had PSMA-positive visceral metastases which were predictably not diagnosed with conventional bone scan. However, SPECT/CT was required to distinguish between soft tissue uptake and overlapping bone. 4 patients had extensive MDP negative bone marrow lesions. 7 patients had superscan character in bone scan; in contrast, extent of red marrow involvement was more evident by PSMA-scan. Only 3 patients had completely equal results in the bone-scan and PSMA-scan. Also more suspicious lesions were detected in 16 patients using PSMA-scan in comparison to bone-scan. In two patients (about 10 %) a PSMA-negative tumor phenotype was present. Conclusion: PSMA-scanning presented a clearly advantage versus bone-scans by reducing the number of equivocal findings, in most patients. SPECT/CT is pivotal to differentiate between benign (e.g. degenerative changes), bone metastases and extra-osseous tumor lesions.

    It is well known that malignant melanoma can metastasize widely. Although these metastases in the gastrointestinal tract usually appear as small 'bull's-eye' or 'target' lesions, there are a few reports of relatively large melanoma metastases. We report five cases of large melanoma lesions metastatic to the alimentary canal. We also emphasise the consideration of a thorough gastrointestinal tract evaluation in patients with malignant melanoma especially if they are symptomatic.

    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.

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

    The purpose of this study was to investigate what pseudo-CT (pCT) strategy is sufficient for online MRI based treatment plan adaptation of a stereotactic treatment for spinal bone metastases. For this purpose, the dosimetric accuracy of five increasingly complex pCT strategies was evaluated using the planning CT data of 20 patients suffering from spinal metastases. For each pCT, a treatment plan was developed and simulated on both the pCT and the original CT data of the patient. The two resulting dose distributions were compared using gamma analysis of 2%/2 mm. In this paper, a Gamma Pass Rate (GPR) of ⩾95% within the Target Volume (TV) was considered clinically acceptable. We additionally demonstrated in this paper the automatic generation of each investigated pCT strategy with the use of dedicated MRI data complemented with pre-treatment CT data of a patient in treatment position. The dosimetric accuracy of a pCT increases when additional bulk densities are utilized for a pCT. However, the dosimetric accuracy of even the most complex ‘bulk density’ pCT strategy used in this study had an average GPR of only 78% within the TV. However, if information on the heterogeneous electron density distribution within the affected vertebral body was available, a clinically acceptable 99% mean GPR was observed. All pCTs could successfully be generated using the MRI data in combination with the CT data of a patient in treatment position. The results presented in this study show that a simple ‘bulk density’ pseudo-CT strategy is not feasible for online MRI based treatment plan adaptation for spinal bone metastases. However, a clinically acceptable result is generated if the information on the heterogeneous electron density (ED) distribution within the affected vertebral bone is available. Therefore, any pCT strategy for this tumor site should include a method which can estimate the heterogeneous ED of the affected vertebral bone. (paper)

    Central nervous system metastases cause grave morbidity in patients with advanced malignancies. Lung cancer, breast cancer, and melanoma are the three most common causes of brain metastases. Although the exact incidence of brain metastases is unclear, there appears to be an increasing incidence which has been attributed to longer survival, better control of systemic disease, and better imaging modalities. Until recently surgical resection of solitary or symptomatic brain metastases, and radiation therapy (either whole-brain radiation therapy or stereotactic radiation) were the mainstay of treatment for patients with brain metastases. The majority of traditional chemotherapies have shown limited activity in the central nervous system, which has been attributed to the blood-brain barrier and the molecular structure of the used agents. The discovery of driver mutations and drugs targeting these mutations has changed the treatment landscape. Several of these targeted small-molecule tyrosine kinase inhibitors do cross the blood-brain barrier and/or have shown activity in the central nervous system. Another major advance in the care of brain metastases has been the advent of new immunotherapeutic agents, for which initial studies have shown intracranial activity. In this chapter, we will review the unique challenges in the treatment of brain metastases. The pertinent clinical studies of chemotherapy in brain metastases will be discussed. The currently reported clinical trials and evidence for use of targeted therapies and immunotherapeutic agents will be emphasized. Copyright © 2018 Elsevier B.V. All rights reserved.

    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.

    Periostin is an extracellular matrix protein that is implicated in the biology of normal bone remodeling and in different cancer cell growth and metastasis. However, there is no information on the role of periostin in multiple myeloma (MM). Thus, we evaluated periostin in six myeloma cell lines in vitro; in the bone marrow plasma and serum of 105 newly diagnosed symptomatic MM (NDMM) patients and in the serum of 23 monoclonal gammopathy of undetermined significance (MGUS), 33 smoldering MM (SMM) patients, 30 patients at the plateau phase post-first-line therapy, 30 patients at first relapse and 30 healthy controls. We found high levels of periostin in the supernatants of myeloma cell lines compared with ovarian cancer cell lines that were not influenced by the incubation with the stromal cell line HS5. In NDMM patients the bone marrow plasma periostin was almost fourfold higher compared with the serum levels of periostin and correlated with the presence of fractures and of diffuse magnetic resonance imaging pattern of marrow infiltration. Serum periostin was elevated in NDMM patients compared with healthy controls, MGUS and SMM patients and correlated with advanced disease stage, high lactate dehydrogenase, increased activin-A, increased bone resorption and reduced bone formation. Patients at first relapse had also elevated periostin compared with healthy controls, MGUS and SMM patients, while even patients at the plateau phase had elevated serum periostin compared with healthy controls. These results support an important role of periostin in the biology of myeloma and reveal periostin as a possible target for the development of antimyeloma drugs.

    Full Text Available The aim of the present study was to investigate the relationship between degenerative bone changes of the head of the mandible and the presence of joint effusion (JE. This study was based on sagittal magnetic resonance imaging (MRI reports of 148 temporomandibular joints (TMJs of 74 patients complaining of pain and/or dysfunction in the TMJ area. The mandible heads were surveyed for osteoarthritis characteristics, which were classified as osteophytosis, sclerosis or erosion. The presence of JE was checked whenever high signal intensity was observed in the articular space. The results evidenced the presence of bone changes in 30% of the sample. Osteophytes and erosions were the changes most commonly observed. JE was reported in 10% of TMJs. The results from the statistical tests revealed that bone changes in the head of the mandible are associated with the presence of JE.

    The aim of this study was to compare the diagnostic and prognostic values of (99m)Tc-MDP-planar bone scintigraphy ((99m)Tc-MDP-BS), (131)I single-photon emission computed tomography/computed tomography ((131)I-SPECT/CT) and (18)F-fluorodeoxyglucose ((18)F-FDG)-PET/CT for the detection of bone metastases from differentiated thyroid cancer (DTC). Eighty patients with DTC with suspected bone metastases from DTC were retrospectively analysed. All patients were examined with (99m)(99m)Tc-MDP-BS, (131)I-SPECT/CT and (18)F-FDG-PET/CT, with a maximum interval of 2 months between scans. The diagnostic performances of (99m)Tc-MDP-BS, (131)I-SPECT/CT and (99m)F-FDG-PET/CT were investigated and compared. Univariate and multivariate analyses were carried out to evaluate the effects of variables on the survival of patients. Out of the 80 patients with 148 foci, 43 with 106 foci were diagnosed as being true positive for bone metastases from DTC. In patient-based analysis, the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of (99m)Tc-MDP-BS were 79.07, 83.78, 85.00, 77.50 and 81.25%, respectively; those of (131)I-SPECT/CT were 93.02, 97.30, 97.56, 92.31 and 95.00%, and those of (18)F-FDG-PET/CT were 86.05, 94.59, 94.87, 85.36 and 87.80%, respectively. In lesion-based analysis, the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of (99m)Tc-MDP-BS were 72.64, 73.81, 87.50, 51.67 and 72.97%, respectively; those of (131)I-SPECT/CT were 92.45, 97.62, 98.99, 83.67 and 93.92%, and those of (18)F-FDG-PET/CT were 85.85, 88.10, 94.50, 71.15 and 86.49%, respectively. Comparing the receiver-operating characteristic area using the McNemar test, both (131)I-SPECT/CT and (18)F-FDG-PET/CT were found to be superior to (99m)Tc-MDP-BS for the detection of bone metastases from DTC in patient-based and lesion-based analyses (PMDP-BS might be completely replaced by (131)I-SPECT/CT in

  8. Approach to the thyroid cancer patient with extracervical metastases.

    Patients with distant, or extracervical, metastases from differentiated thyroid cancer require multimodality diagnostic, therapeutic, and monitoring approaches. Whereas cure is the initial goal, especially in those with small, radioiodine-avid pulmonary metastases, improved survival and management of symptoms become the primary objective in many patients with persistent disease, especially those with bone metastases. Levothyroxine therapy with suppression of serum TSH is a primary therapy in all patients with advanced differentiated thyroid cancer, and this therapy has been shown to improve overall survival and slow disease progression. Radioiodine is also an important systemic therapy for those patients with radioiodine-avid disease who respond to this targeted therapy. In this review, we compare standard fixed-dose radioiodine therapy vs. the dosimetric approach. Directed therapy such as external beam radiotherapy, surgery, and embolization is generally considered for large or painful lesions. Careful collaborations with multiple specialties through tumor boards or other mechanisms help to optimize complex management decisions in these patients with advanced thyroid cancer. Multimodality monitoring focused on the organ of interest such as pulmonary [computed tomography (CT)], bone (magnetic resonance imaging, CT, bone scan), and brain (CT, magnetic resonance imaging) metastases as well as general metastatic surveillance (bone scan, (18)F-fluorodeoxyglucose-positron emission tomography) aid decision making about careful monitoring vs. directed or systemic therapy. (18)F-fluorodeoxyglucose-positron emission tomography imaging has an additional role in patient prognosis and guiding directed therapy for fluorodeoxyglucose-avid lesions. Patients with asymptomatic, stable, radioiodine-resistant metastases may be carefully monitored for disease progression.

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

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

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

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

    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

    An instance of malignant endothelioma, primary in the aorta, metastasizing to intestine and bone, is reported. The aortic tumor was successfully resected. The unexpected finding of a large hepatic growth at autopsy raised the possibility that the aortic neoplasm was a metastasis. Histochemical, immunologic, and ultrastructural studies supported the diagnosis of an endothelial neoplasm. Although a number of malignant aortic and large vessel tumors have been reported, only four previous instances appear to be endotheliomatous.

    Full Text Available Urachal carcinoma (UC is a rare tumor mainly affecting middle-aged males. Metastases occur most frequently in lymph nodes and the lungs. There are no standard adjuvant and metastatic treatments. We report the case of a 36-year-old female with UC treated with partial cystectomy who relapsed 3 years after surgery with left choroidal, lung, mediastinal lymph node, right adrenal, mammary, and bone metastases as well as peritoneal carcinomatosis. She obtained a partial response after 10 cycles of chemotherapy with a modified docetaxel, cisplatin and 5-fluorouracil (mTPF regimen. This is the first report on the use of the mTPF regimen in UC and on the existence of choroidal, adrenal, and mammary metastases.

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

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

    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 aim of this study was to compare the metabolic activity of metastatic foci from breast and prostate cancer patients as scanned by fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) and by technetium-99m methyl diphosphonate ( 99m Tc-MDP) bone scan (BS). Forty one patients were studied, divided into 2 groups based on histologically confirmed diagnosis: a) Breast cancer group, 23 women, mean age: 61±12 years, range: 37-79 years and, b) Prostate cancer group, 18 men, mean age 68±8 years, range: 52-82 years. Another group of 17 non cancer atherosclerotic subjects 9 women and 8 men, of mean age and age range similar to the above were also studied for comparison. The R index (the total count rate in bone metastases divided by the total count rate in a contralateral area), the maximum semi-quantitative standardized uptake value (SUVmax) of BS lesions and the mean number of metastases were evaluated. For the metastatic findings in the PET/CT scans the automatic method of contouring with 50% background cut-off was used, while for the 99m Tc-MDP BS metastases were delineated manually. The mean R index of the bone metastatic foci studied by 18 F-FDG PET/CT was 1.89±0.69 for Groups I and II patients. There was no significant difference of the R index between prostate cancer and breast cancer metastases (1.95±0.86 vs 1.83±0.52). The average SUVmax value was significantly higher in breast cancer patients than in prostate cancer patients (5.15±2.54 vs 4.01±1.71; PMDP BS scan was much less than by the 18 F-FDG PET/CT. No significant correlation was noticed in the metabolic activity-glucose utilization of metastatic bone foci between breast and prostate cancer cases. This observation validates the independent value of analyzed diagnostic methods and suggests negligible influence of glucose utilization in bone re-modeling in the above metastatic cancer cells. The 18 F-FDG PET/CT bone scan was much better in diagnosing

    Type I collagen is the major constituent of bone and its breakdown products are increasingly used as sensitive markers of bone resorption. The N-terminal peptide-bound crosslinks of type I collagen (NTX) can be measured in urine and is useful for the monitoring of patients with metastatic bone disease. Studies have shown that raised NTX levels in metastatic bone disease correlate with an increased risk of complications and pathological fracture. The development of accurate and instantaneous point of care devices (POCD) would facilitate patient treatment and avoid delays in awaiting results from specialist laboratories. This study assesses the clinical performance of a single use POCD (OSTEOMARK NTx Point of Care Rx Home Use) to monitor NTX levels in patients with metastatic bone disease. NTX was measured in duplicate in 136 urine samples from patients attending clinic with metastatic bone disease using the POCDs. In our centre the frequency of bisphosphonate treatment is dependent on the NTX level, which is categorised into three groups (0-50, 50-100 and >100 nmol BCE/mmol creatinine). We used these categories to compare the clinical performance of the POCDs to that of a laboratory immunoassay. From a total of 272 devices, 231 (84.9%) successfully recorded a value in nM BCE/mM creatinine. Statistical analysis of the measure of agreement between POCD and laboratory assay found moderate agreement between the two assays (kappa 0.508). Out of the 72 samples with a laboratory assay value of 100, 19 (95.0%) were found to be within the same category using POCDs. The measurement of urinary NTX by POCD appears to be a viable option for the monitoring of metastatic cancer patients. Whilst POCDs appear to record higher values than laboratory assays, the correlation between devices is good and with further research the NTX categories could be modified to accommodate this variation.

    The aim of this study was to demonstrate the renal safety equivalence of ibandronate 6 mg infused over 15 min versus 60 min, in patients with bone metastases of breast cancer. Patients were females having breast cancer with at least one bone metastasis. Exclusion criteria were renal failure (creatinine clearance jaw disorder or uncontrolled severe disease. Eligible patients were randomly assigned to receive nine ibandronate 6 mg i.v. infusions over either 15 min or 60 min. The primary outcome was the 95% confidence interval (CI) of the difference in creatinine clearance between groups, 28 days after the last infusion. The equivalence margin was ±8 mL/min. Overall 334 patients were randomized (165-15 min infusions vs. 169 to 60 min infusions, 325 (159 vs. 166) were analyzed by intent-to-treat, and 312 (151 vs. 161) were analyzed per protocol. Per protocol, the 15 min-60 min difference in creatinine clearance [95% CI] was -3.00 [-8.18, 2.18]. By intent-to-treat, this difference was-2.91 [-7.99, 2.16]. Death and serious adverse event rates did not differ between groups. Three serious adverse events were considered related to ibandronate: an osteonecrosis of the jaw (15-min group), a pain in jaw and an enamel cracking (60-min group). Two renal failures, reported in the 60 min group, were not considered related to ibandronate. None occurred in the 15 min group. Ibandronate may be infused over 15 min without clinically significant consequence on renal safety. Copyright © 2011 Elsevier Ltd. All rights reserved.

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

    Purpose: With a growing demand of alpha-emitting radiopharmaceuticals, especially Xofigo ({sup 223}RaCl{sub 2}) which is used in the treatment of metastatic bone disease, the optimization of dosimetry becomes necessary. Indeed, in Europe, as stated on the council directive 2013/59/euratom, exposures of target volumes for radiotherapeutic purposes shall be individually planned taking into account that doses to non-target volumes and tissues shall be as low as reasonably achievable. To that aim, the possibility of imaging {sup 223}Ra was first investigated. Methods: The experiments were conducted at the Hopital Europeen Georges Pompidou with an Infinia Hawkeye 4 gamma camera, equipped with a medium-energy collimator. Imaging parameters, such as sensibility, spatial resolution and energy spectrum, were determined using several physical phantoms with a source of 6 MBq of {sup 223}Ra. Bone metastases were modeled with a NEMA Body Phantom to investigate image degradation based on the concentration of {sup 223}Ra. Results: The acquired energy spectrum allowed to visualize several photon peaks: at 85, 154 and 270 keV. Camera sensitivity measured from the phantom study was 102.3 cps/MBq for the 85 keV ± 20 %, 89.9 cps/MBq for the 154 ± 20 % window and 65.4 cps/MBq for the 270 ± 10 % window. The spatial resolution (full-width at half-maximum) was respectively 1.7, 1.9 and 1.8 cm for the three energy windows. SPECT/CT images of NEMA Body Phantom without and with attenuation have permitted to determine the best reconstruction parameters. Conclusion: This study has demonstrated that it is possible to obtain clinically relevant information from images of {sup 223}Ra. All these results will be valuable to analyze biodistribution imaging of the radiopharmaceutical in the patient body and go further in the reconstruction of patient images in order to personalize the dosimetry.

    Full Text Available Background. Mobilization of c-Kit+ hematopoietic cells (HCs contributes to tumor vascularization. Whereas survival and proliferation of HCs are regulated by binding of the stem cell factor to its receptor c-Kit, migration of HCs is directed by stromal cell-derived factor (SDF-1. Therefore, targeting migration of HCs provides a promising new strategy of anti-tumor therapy. Methods. BALB/c mice (=16 were pretreated with an anti-c-Kit antibody followed by implantation of CT26.WT-GFP colorectal cancer cells into dorsal skinfold chambers. Animals (=8 additionally received a neutralizing anti-SDF-1 antibody. Animals (=8 treated with a control antibody served as controls. Investigations were performed using intravital fluorescence microscopy, immunohistochemistry, flow cytometry and western blot analysis. Results. Blockade of c-Kit significantly enhanced tumor cell engraftment compared to controls due to stimulation of tumor cell proliferation and invasion without markedly affecting tumor vascularization. C-Kit blockade significantly increased VEGF and CXCR4 expression within the growing tumors. Neutralization of SDF-1 completely antagonized this anti-c-Kit-associated tumor growth by suppression of tumor neovascularization, inhibition of tumor cell proliferation and reduction of muscular infiltration. Conclusion. Our study indicates that bone marrow suppression via anti-c-Kit pretreatment enhances tumor cell engraftment of colorectal metastases due to interaction with the SDF-1/CXCR4 pathway which is involved in HC-mediated tumor angiogenesis.

  6. Strontium-89 for prostate cancer with bone metastases. The potential of cancer control and improvement of overall survival

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

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

    Otto Warburg observed in 1924 that cancer cells were dependent exclusively on glycolysis for the production of energy even in the presence of oxygen (the 'Warburg effect'). Consequently, cancer cells require ~19 times more glucose uptake to obtain equivalent amounts of energy as normal cells. The Warburg effect is the scientific basis for positron emission tomography (PET), which has markedly improved cancer detection. During chemotherapy, cancer cells may upregulate their expression of multi-drug resistance proteins and ultimately cause treatment failure. As multi-drug resistance proteins require energy to operate, the present report evaluated the potential clinical efficacy of lowering blood glucose with insulin during chemotherapy for a patient with advanced pulmonary adenocarcinoma with multiple metastases. A 64-year-old male was admitted to the Department of Medical Oncology at Changzhou Tumor Hospital (Changzhou, China) due to an irritating cough and multiple bone pain. PET/computed tomography (CT) with F-18 fluorodeoxy glucose (18F-FDG) identified multiple hypermetabolic foci in the right hilum, right upper lung, shoulder blades, thoracic vertebrae, lumbar, sacrum, bilateral iliac crest and pelvis. Additionally, magnetic resonance imaging detected multiple metastases in the brain. The patient received 56 repeat treatments with insulin to induce hypoglycemia combined with reduced doses of chemotherapy over an 8-month period. For each treatment, insulin at 0.2 U/kg body weight was injected intravenously (i.v.), and when blood glucose level reached 2.5-3.0 mmol/l, navelbine (10 mg), cisplatin (10 mg) and fluorouracil (250 mg) were injected (i.v.) over a period of ~10 min. The patient's blood glucose level was returned to normal immediately after chemotherapy with an i.v. injection of 20 ml 50% glucose solution. During the 8-month chemotherapy regimen, the patient received two PET/CT follow-ups. The results demonstrated that the levels of 18F-FDG uptake in all

    The successful labelling of bisphosphonates (BP) with 68 Ga using macrocyclic chelators such as the based triazacyclononane (NO2AP) is a step forward in the in-house availability of a novel bone-seeking PET radiopharmaceutical with dual advantage of PET/CT imaging and generator production. In this study, we compared the novel generator-based skeletal radiotracer 68 Ga-1,4,7-triazacyclonone-1,4-diacetic acid ( 68 Ga-NO2AP-BP) with sodium fluoride ( 18 F-NaF) for the detection of skeletal metastases in breast cancer patients. In addition, dosimetric analysis of 68 Ga-NO2AP-BP was performed in a subset of patients. This was a prospective study of histopathologically proven cases of breast cancer patients who were referred for bone scintigraphy and underwent positron emission tomography/computed tomography (PET/CT) with 18 F-NaF and 68 Ga-NO2AP-BP within a week in random order. The scans of each patient were compared both qualitatively for image quality and quantitatively for number of lesions and SUVmax of lesions. Dosimetric analysis was performed in five patients. Their PET/CT scans were acquired at multiple time points and urine and blood samples were collected. Dosimetric calculations were performed using OLINDA/EXM 1.1 software. Statistical analysis was done using Stata 13 (StataCorp) software package. An agreement analysis regarding number of lesions detected with the two skeletal radiotracers was carried out. The image quality of 68 Ga-NO2AP-BP PET/CT scans were comparable to that of 18 F-NaF. There was no statistically significant difference in the SUVmax of lesions, normal bone and lesion to background ratio between the two skeletal radiotracers. There was good agreement in the number of lesions detected by both skeletal radiotracers. The mean whole body effective dose for 68 Ga-NO2AP-BP was 0.00583 mSv/MBq and the effective dose equivalent was 0.0086 mSv/MBq. The excellent lesion detection agreement between 68 Ga-NO2AP-BP and 18 F-NaF favours the former as

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

    The aim was to systematically extrapolate the occurrence, risk factors, prognostic characteristics, management and outcome of bone metastases (BM) and skeletal related events (SREs) of breast cancer survivors in the real world clinical setting. A systematic literature search of PubMed, Web of Science, EMBASE OvidSP and EBSCO Academic Search Complete was conducted. Published prospective and retrospective papers investigating BM and SREs in breast cancer patients in non-trial settings were identified and systematically reviewed. Twenty-four studies met the inclusion criteria. Incidences of BM based on new diagnosis, length of BM-free interval (BMFI) and number and sites of BM were detected by 17 of 24 studies. Seven studies included in the review were subjected to analyses of risk factors for BM. Developments of SREs regarding the occurrence ratio of total and specific SREs, SERs-free interval (SREFI) and the first-line therapy for SREs were observed in 16 of 24 studies. Out of 5 studies, we extracted uni- and multivariate analysis of risk factor for SREs and out of 16 studies - predictors for survival in breast cancer patients with BM. BM and SREs are common problems in non-trial breast cancer populations. Patient demographics, clinical stage, tumor pathological type, molecular receptors status are significantly risk factors for incidence of BM, SREs and the survival. The unique characteristics of BM and SREs in breast cancer patients should be taken into account in future randomized controlled trials, as to optimize individual treatment options and assure a maximally long good quality of life.

    The purpose of this paper is to document the use of intravenous (IV) bisphosphonates for prevention of skeletal-related events (SREs) in patients with bone metastases (BM) due to breast cancer (BC), lung cancer (LC), or prostate cancer (PC). Using data from two large US health systems, we identified all patients aged ≥ 18 years with primary BC, LC, or PC and newly diagnosed BM between 1/1/1995 and 12/31/2009. Starting with the diagnosis of BM, we reviewed medical and administrative records for evidence of receipt of IV bisphosphonates (zoledronic acid or pamidronate) and occurrence of SREs. Initiation of IV bisphosphonates prior to occurrence of an SRE was designated "primary prophylaxis"; use following an SRE was designated "secondary prophylaxis". We identified a total of 1,193 patients with newly diagnosed BM, including 400 with BC, 332 with LC, and 461 with PC. Use of IV bisphosphonates was substantially higher in BC (55.8 % of all patients) than in LC (14.8 %) or PC (20.2 %). Use of IV bisphosphonates was fairly evenly split between primary and secondary prophylaxis in BC (26.3 vs. 29.5 %, respectively) and PC (10.6 vs 9.5 %); in LC, however, primary prophylaxis was much less common than secondary prophylaxis (4.8 vs 9.9 %). Almost one half of all patients with BM due to BC, and substantially more with LC and PC, do not receive IV bisphosphonates. Among patients receiving such therapy, treatment often is not initiated until after the occurrence of an SRE. Our study suggests that IV bisphosphonates may be substantially underutilized in patients with BM due to these common cancers.

    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)

    The detection of occult bone metastases is a key factor in determining the management of patients with renal cell carcinoma (RCC), especially when curative surgery is considered. This prospective study assessed the sensitivity of (18)F-labelled sodium fluoride in conjunction with positron emission tomography/computed tomography ((18)F-NaF PET/CT) for detecting RCC bone metastases, compared with conventional imaging by bone scintigraphy or CT. An adaptive two-stage trial design was utilized, which was stopped after the first stage due to statistical efficacy. Ten patients with stage IV RCC and bone metastases were imaged with (18)F-NaF PET/CT and (99m)Tc-labelled methylene diphosphonate ((99m)Tc-MDP) bone scintigraphy including pelvic single photon emission computed tomography (SPECT). Images were reported independently by experienced radiologists and nuclear medicine physicians using a 5-point scoring system. Seventy-seven lesions were diagnosed as malignant: 100% were identified by (18)F-NaF PET/CT, 46% by CT and 29% by bone scintigraphy/SPECT. Standard-of-care imaging with CT and bone scintigraphy identified 65% of the metastases reported by (18)F-NaF PET/CT. On an individual patient basis, (18)F-NaF PET/CT detected more RCC metastases than (99m)Tc-MDP bone scintigraphy/SPECT or CT alone (P = 0.007). The metabolic volumes, mean and maximum standardized uptake values (SUV mean and SUV max) of the malignant lesions were significantly greater than those of the benign lesions (P < 0.001). (18)F-NaF PET/CT is significantly more sensitive at detecting RCC skeletal metastases than conventional bone scintigraphy or CT. The detection of occult bone metastases could greatly alter patient management, particularly in the context when standard-of-care imaging is negative for skeletal metastases. © The Author 2015.

    Recent many studies have shown that whole body "diffusion-weighted imaging with background body signal suppression" (DWIBS) seems a beneficial tool having higher tumor detection sensitivity without ionizing radiation exposure for pediatric tumors. In this study, we evaluated the diagnostic performance of whole body DWIBS and 18 F-FDG PET/CT for detecting lymph node and bone metastases in pediatric patients with neuroblastoma. Subjects in this retrospective study comprised 13 consecutive pediatric patients with neuroblastoma (7 males, 6 females; mean age, 2.9 ± 2.0 years old) who underwent both 18 F-FDG PET/CT and whole-body DWIBS. All patients were diagnosed as neuroblastoma on the basis of pathological findings. Eight regions of lymph nodes and 17 segments of skeletons in all patients were evaluated. The images of 123 I-MIBG scintigraphy/SPECT-CT, bone scintigraphy/SPECT, and CT were used to confirm the presence of lymph node and bone metastases. Two radiologists trained in nuclear medicine evaluated independently the uptake of lesions in 18 F-FDG PET/CT and the signal-intensity of lesions in whole-body DWIBS visually. Interobserver difference was overcome through discussion to reach a consensus. The sensitivities, specificities, and overall accuracies of 18 F-FDG PET/CT and whole-body DWIBS were compared using McNemer's test. Positive predictive values (PPVs) and negative predictive values (NPVs) of both modalities were compared using Fisher's exact test. The total numbers of lymph node regions and bone segments which were confirmed to have metastasis in the total 13 patients were 19 and 75, respectively. The sensitivity, specificity, overall accuracy, PPV, and NPV of 18 F-FDG PET/CT for detecting lymph node metastasis from pediatric neuroblastoma were 100, 98.7, 98.9, 95.0, and 100%, respectively, and those for detecting bone metastasis were 90.7, 73.1, 80.3, 70.1, and 91.9%, respectively.

    Objective: To present computed tomography findings observed in four patients submitted to radical nephrectomy for renal cell carcinoma who developed pancreatic metastases afterwards. Materials and methods: The four patients underwent radical nephrectomy for stage Tz1 (n=2) and stage T3a (n=2) renal cell carcinoma. The mean interval between nephrectomy and detection of pancreatic metastases was eight years. Two asymptomatic patients presented with solitary pancreatic metastases (confined to the pancreas). Two symptomatic patients presented with single and multiple pancreatic metastases, both with tumor recurrence in the contralateral kidney. Results: Computed tomography studies demonstrated pancreatic metastases as solitary (n=2), single (n=1) or multiple (n=1) hypervascular lesions. Partial pancreatectomy was performed in two patients with solitary pancreatic metastases and both are free of disease at four and two years after surgery. Conclusion: Pancreatic metastases from renal cell carcinoma are rare and can occur many years after the primary tumor presentation. Multiple pancreatic metastases and pancreatic metastases associated with tumor recurrence in the contralateral kidney are uncommon. Usually, on computed tomography images pancreatic metastases are visualized as solitary hypervascular lesions, simulating isletcell tumors. Surgical management should be considered for patients with solitary pancreatic lesions. (author)

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

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

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

    This retrospective study, including 275 patients who underwent stereotactic radiotherapy due to brain metastases between 2003 and 2008, investigates influencing factors regarding cerebral control and survival, symptomatic effects and a potential benefit for patients older than 70 years. We were able to identify risk factors for remote brain failure which leads to a therapeutic recommendation. Furthermore we confirm a positive symptomatic effect and a benefit of stereotactic readiotherapy for patients over 70 years.

    We have developed a {sup 186}Re-mercaptoacetylglycylglycylglycine complex-conjugated bisphosphonate ({sup 186}Re-MAG3-HBP) for the treatment of painful bone metastases. We assumed competitive inhibitors of protein binding to be useful for procuring a favorable biodistribution of {sup 186}Re-MAG3-HBP for the palliation of bone pain because it has been reported that the concurrent administration of {sup 99m}Tc-MAG3 and drugs with high affinity for serum protein produced competitive displacement at specific binding sites and enhanced total clearance and tissue distribution. The displacement effects of several protein-binding inhibitors on the protein binding of {sup 186}Re-MAG3-HBP were investigated. Biodistribution experiments were performed by intravenously administering {sup 186}Re-MAG3-HBP into rats with ceftriaxone as a competitive protein-binding inhibitor or saline. The protein binding of {sup 186}Re-MAG3-HBP in rat serum, human serum, and a human serum albumin solution was significantly decreased by the addition of ceftriaxone, which has high affinity for binding site I on serum albumin. In the biodistribution experiments, pretreatment with ceftriaxone enhanced the clearance of the radioactivity of {sup 186}Re-MAG3-HBP in blood and nontarget tissues but had no effect on accumulation in bone. The findings suggested that the use of protein-binding competitive inhibitors would be effective in improving the pharmacokinetics of radiopharmaceuticals with high affinity for serum protein.

    The objective of this study was to determine the utility of {sup 99m} Tc-(V)- Dmsa whole body planar scan in the diagnostic of skeletal metastases. Nineteen patients were studied, having a recent {sup 99m} Tc-HDP bone scan reporting different pathologies (3 normal scans, 5 equivocal scans and 11 with disseminated bone metastases). 72 hours later, a whole body planar scan was obtained at 3 and 24 hours after the i.v. administration of {sup 99m} Tc-(V)-Dmsa. Counts per pixel were determined in regions of interest drawn over metastases sites and in normal tissue, and were correlated with the bone scan. Statistical analysis was carried out by using the Kruskal-Wallis analysis of variance followed by Mann Whitney U test. Other comparisons were done with Momios, chi square and t Student tests. 273 lesions were studied in the whole body bone scan and 184 lesions in the {sup 99m} Tc-(V)-Dmsa scintigraphy (t Student test n.s.). The tumor to normal tissue ratios were 3.3 (+/- 0.521) and the soft to normal tissue ratios were 1.01 (+/- 0.01), Mann Whitney p< 0.01. The study sensitivity was 92% an overall specificity was 97%. As conclusions we have that {sup 99m} Tc-(V)-Dmsa scintigraphy is an useful choice in the diagnostic of bone metastases when the whole body planar bone scan ({sup 99m} Tc- HDP) is equivocal or abnormal. It also points out other lesions such as in bone and in soft tissue. (Author)

    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 symptom particularly of (micro) PTC. In contrast follicular 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 %).

    Metastatic bone disease is a frequent complication of advanced non-small-cell lung cancer and causes skeletal-related events which result in a poor prognosis. A standard method to assess the therapeutic response of bone metastases does not currently exist. We used dynamic contrast-enhanced MRI to obtain quantitative measures to assess the suitability of this technique to gauge therapeutic response to vinorelbine-cisplatin plus rh-endostatinfor previously untreated non-small cell lung cancer with bone metastases. We did a phase 4, randomised, prospective, double-blind, placebo-controlled clinical trial in Shanghai Sixth People's Hospital, Shanghai, China. Inclusion criteria were non-small-cell lung cancer patients with bone metastases confirmed by pathology or cytology; available imaging data of pelvic metastatic lesions; aged 18 to 75 years old; expected survival at least 3 months; not receiving taxane, bevacizumab, thalidomide, rh-endostatin, or bisphosphonate; not having radiation therapy within 3 months of enrollment into study; normal results of routine blood tests, liver and kidney function, and electrocardiogram; absence of cardiovascular disease, autoimmune disease, vasculitis, severe infection, diabetes, and other concomitant disease; and signed informed consent. Exclusion criteria were receiving granulocyte colony stimulating factor or granulocyte-macrophage colony stimulating factor during chemotherapy, intolerance to adverse reaction, and allergy to contrast agents. Patients were randomly assigned to treatment group and control group at a ratio of 2:1 by random code generation by an independent biostatistician in a double-blind fashion. Participants received either vinorelbine-cisplatin plus rh-endostatin or vinorelbine-cisplatin plus placebo. Vinorelbine (25 mg/m 2 ) and cisplatin (75 mg/m 2 ) were administered intravenously on the first day of a 21 day cycle. Patients received rh-endostatin (7·5 mg/m 2 ) or placebo on days 1-14 of a cycle. The primary

    Bone is one of the organs to which cancer metastasizes most frequently. However, it is not a vital organ, therefore, survival after the occurrence of osseous metastasis is relatively favorable. Improvements of medical treatment bring prolonged survival to patients with osseous metastases. But this makes us to recognize the importance of quality of life (QOL) due to several factors, including pain. It is important for oncologists to know how to deal with such painful osseous metastases, as pain relief may enable patients to live their remaining lives to the fullest. Strontium-89 (89Sr) has been used worldwide as in Japan, while being reported to have positive effects on pain relief and QOL improvement in patients with osseous metastases. This review paper is aimed to present not only the history, roles, and medical characters of 89Sr, but also new aspects, such as how to use bone turnover markers, which location of osseous metastases is suitable for effective use of 89Sr. (author)

    The most common sites of metastatic differentiated thyroid cancer are the neck lymph nodes, while distant metastases typically involve the lungs, the bones, and less frequently the brain. Uncommon metastatic sites include the liver, adrenal gland, kidney, pancreas, and skin. The epidemiological aspects of thyroid metastases in rare sites are largely unknown and their identification could have a significant impact on patients management. A mini-series of unusual metastatic sites of thyroid carcinoma is proposed as a contribution to current knowledge on anatomopathological characteristics and clinical outcome. Of the six cases that were assessed, the metastases were the following: skin metastases (2), skin and pancreas metastases (1), renal metastasis (1), adrenal metastasis (1), and liver metastasis (1). In our experience, metastases in rare sites do not always represent a negative prognostic factor for disease outcome. In fact they can occur as single distant lesion and if surgically resectable, their treatment can also lead to local disease remission.

  12. Prevalence of Prostate Cancer Metastases after Intravenous Inoculation Provides Clues into the Molecular Basis of Dormancy in the Bone Marrow Microenvironment

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

    The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation.

    Currently, two radiopharmaceuticals are available in France to treat painful bone metastases Metastron for prostate cancers and Quadramet whatever is the primitive tumour. Efficacy is high since 70% of response is observed with 30% of complete response, allowing diminution and even withdrawal of antalgic medication. Toxicity is purely hematologic and is predictable in time, moderate and always transient. The interest is to use internal radiotherapy very early in the course of disease, as soon as there is one painful osseous site (and several metastatic localizations on bone scan), to treat pain, to prevent pain on other sites, and to delay recourse to other forms of therapy (such as morphinic with their side effects) and thus to ensure adequate quality of life for as long as possible.

    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.

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

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

    Avascular necrosis of bone (AVN) is an important complication of systemic lupus erythematosus (SLE). Corticosteroid therapy has been underlined as a main risk factor for osteonecrosis. However, AVN development in patients who have never received corticosteroid and the absence of AVN in the majority of the patients, who received corticosteroid, propose a role for non-corticosteroid risk factors in AVN development. This case-control study included two subsets: oral corticosteroid (66 AVN and 248 non-AVN patients) and pulse-therapy subset (39 AVN and 312 non-AVN patients) who have attended our Lupus clinic from 1979 to 2009. Patients received similar cumulative dose corticosteroid, equal maximum dose and 1-year maximum dose of corticosteroid. The demographic data (including sex, age of disease onset, age at the diagnosis of AVN), organs involvement, SLE Disease Activity Index (SLEDAI), Systemic Lupus International Collaborating Clinics/American College of Rheumatology-Damage index (SLICC/ACR-DI), number of disease flare ups were compared between two subsets. The mean age of SLE onset was younger (P value = 0.04) in the AVN patients. In oral corticosteroid subset, malar rash (P value < 0.001) and oral ulcer (P value = 0.003) were seen more frequently in non-AVN patients, whereas psychosis (P value = 0.03) was significantly more prevalent AVN subset in oral corticosteroid subset. In corticosteroid pulse subset, no significant difference in clinical features was noted. In oral corticosteroid subset, younger age of disease onset and psychosis were significantly associated with AVN, whereas malar rash and oral ulcer showed negative association AVN.

    The objective of this study was to support our hypothesis that surgical resection of abdominal metastases of melanoma, regardless of symptomatology, could provide prolonged palliation and improved survival. We performed a retrospective chart review at M.D. Anderson Cancer Center. A series of 251 melanoma patients (stages I, II, or III at registration) who developed intraabdominal metastases during follow-up were studied. Altogether, 96 patients underwent 119 laparotomies; 51 underwent endoscopic or percutaneous procedures; and 116 patients were treated medically. Surgery was associated with a median survival of 11 months, significantly longer than that with other treatment (p < 0.001). Tumor was extirpated during 37% of the first laparotomies, and in an additional 33% very good palliation was achieved with incomplete resection. Tumor extirpation was associated with 10-month symptom-free survival (SFS), significantly longer than that with any other approach (p < 0.0001). In the nonsurgically treated patients, good palliation was achieved in 8% to 17% of patients with no complete response. The median SFS after surgery was 5 months, but 23% of patients were symptom-free more than 12 months; 87 patients with minimal symptoms; and 72 severely symptomatic patients underwent surgery. Complete resection was feasible in 42% and 34%, respectively. Surgery was associated with 12 months median survival in both groups. There was a significant survival benefit from surgery in patients with gastrointestinal (GI) tract metastases in contrast to those who had non-GI metastases. For the 96 surgically treated patients, a time interval of more than 4 years between diagnosis of the primary lesion and the abdominal recurrence predicted decreased risk of death (p = 0.038). The 30-day postoperative complication and mortality rates were 19.0% and 3.3%, respectively. Complete surgical resection of melanoma metastases in the abdomen is associated with median and symptom-free survival

    Full Text Available Secondary osseous involvement in lymphoma is more common compared to primary bone lymphoma. The finding of osseous lesion can be incidentally discovered during the course of the disease. However, osseous metastases are infrequently silent. Detection of osseous metastases is crucial for accurate staging and optimal treatment planning of lymphoma. The aim of imaging is to identify the presence and extent of osseous disease and to assess for possible complications such as pathological fracture of the load-bearing bones and cord compression if the lesion is spinal. We are presenting two patients with treated lymphoma who were in complete remission. On routine follow-up contrast enhanced CT, there were new osteoblastic lesions in the spine worrisome for metastases. Additional studies were performed for further evaluation of both of them which did not demonstrate any corresponding suspicious osseous lesion. The patients have a prior history of chronic venous occlusive thrombosis that resulted in collaterals formation. Contrast enhancement of the vertebral body marrow secondary to collaterals formation and venous flow through the vertebral venous plexus can mimic the appearance of spinal osteoblastic metastases.

    Two cases of osteogenic sarcoma with skeletal muscle metastases are described. A 40-year-old woman presented with progressive swelling of both calves and a soft tissue back lump. She had been diagnosed with mandibular chondroblastic osteogenic sarcoma 6 years earlier. Radiographs showed calcified masses. MRI scans and bone scintigraphy revealed multiple soft tissue masses in both calves. Bone scintigraphy also showed uptake in the back lump, right thigh and left lung base. Biopsy confirmed metastatic chondroblastic osteogenic sarcoma, which initially responded well to chemotherapy. However, the metastatic disease subsequently progressed rapidly and she died 21 months after presentation. The second case concerns a 20-year-old man who presented with a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector spinae and gluteal muscles. The patient's disease progressed rapidly and he died 30 months after presentation. (orig.)

The second case concerns a 20-year-old man who presented with a pathologic fracture of the humerus, which was found to be due to osteoblastic osteogenic sarcoma. He developed cerebral metastases 17 months later, followed by metastases at other sites. Calcified masses were subsequently seen on radiographs of the abdomen and chest. CT scans confirmed the presence of densely calcified muscle metastases in the abdominal wall, erector spinae and gluteal muscles. The patient`s disease progressed rapidly and he died 30 months after presentation. (orig.) With 6 figs., 29 refs.

    The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : < 5 mm (n=16), 5-10 mm (n=12), and > 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation. (author). 21 refs., 1 tab., 6 figs.

    EML4-ALK lung cancer accounts for approximately 3-7% of non-small-cell lung cancer cases. To investigate the molecular mechanism underlying tumor progression and targeted drug sensitivity/resistance in EML4-ALK lung cancer, clinically relevant animal models are indispensable. In this study, we found that the lung adenocarcinoma cell line A925L expresses an EML4-ALK gene fusion (variant 5a, E2:A20) and is sensitive to the ALK inhibitors crizotinib and alectinib. We further established highly tumorigenic A925LPE3 cells, which also have the EML4-ALK gene fusion (variant 5a) and are sensitive to ALK inhibitors. By using A925LPE3 cells with luciferase gene transfection, we established in vivo imaging models for pleural carcinomatosis, bone metastasis, and brain metastasis, all of which are significant clinical concerns of advanced EML4-ALK lung cancer. Interestingly, crizotinib caused tumors to shrink in the pleural carcinomatosis model, but not in bone and brain metastasis models, whereas alectinib showed remarkable efficacy in all three models, indicative of the clinical efficacy of these ALK inhibitors. Our in vivo imaging models of multiple organ sites may provide useful resources to analyze further the pathogenesis of EML4-ALK lung cancer and its response and resistance to ALK inhibitors in various organ microenvironments. © 2015 The Authors.

    Full Text Available Background: Brain metastases are a common manifestation of systemic cancer and exceed primary brain tumors in number and are a significant cause of neurologic problems. They affect 20-40% of all cancer patients. Aggressive management of brain metastases is effective in both symptom palliation and prolonging the life. Radiotherapy has a major role to play in the management of brain metastases. AIM: The aim of the study was to know the outcome of palliative radiotherapy in symptomatic brain metastases in terms of improvement in their performance status. Materials and Methods: This is a retrospective study of 63 patients diagnosed to have brain metastases and treated with palliative whole brain radiotherapy to a dose of 30 Gy in 10 fractions over two weeks between June 1998 and June 2007. Diagnosis was done in most of the cases with computed tomography scan and in a few with magnetic resonance imaging. Improvement in presenting symptoms has been assessed in terms of improvement in their performance status by using the ECOG scale. Results: Fifty-four patients completed the planned treatment. Eight patients received concurrent Temozolamide; 88% of patients had symptom relief at one month follow-up; 39/54 patients had a follow-up of just one to three months. Hence survival could not be assessed in this study. Conclusion: External beam radiotherapy in the dose of 30 Gy over two weeks achieved good palliation in terms improvement in their performance status in 88% of patients. Addition of concurrent and adjuvant Timozolamide may improve the results.

    Objective: The spine is the most common location for bone metastases. Since cure is not possible, local control and relief of symptoms is the basis for treatment, which is grounded on the use of conventional radiotherapy. Recently, spinal radiosurgery has been proposed for the local control of spinal metastases, whether as primary or salvage treatment. Consequently, we carried out a literature review in order to analyze the indications, efficacy, and safety of radiosurgery in the treatment of spinal metastases. Methods: We have reviewed the literature using the PubMed gateway with data from the Medline library on studies related to the use of radiosurgery in treatment of bone metastases in spine. The studies were reviewed by all the authors and classified as to level of evidence, using the criterion defined by Wright. Results: The indications found for radiosurgery were primary control of epidural metastases (evidence level II), myeloma (level III), and metastases known to be poor responders to conventional radiotherapy – melanoma and renal cell carcinoma (level III). Spinal radiosurgery was also proposed for salvage treatment after conventional radiotherapy (level II). There is also some evidence as to the safety and efficacy of radiosurgery in cases of extramedullar and intramedullar intradural metastatic tumors (level III) and after spinal decompression and stabilization surgery. Conclusion: Radiosurgery can be used in primary or salvage treatment of spinal metastases, improving local disease control and patient symptoms. It should also be considered as initial treatment for radioresistant tumors, such as melanoma and renal cell carcinoma. (author)

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

    The authors present the changes in the immune system in tumor-bearing hosts that may influence the development of progression of metastases. Included are mononuclear cell infiltration of metastases; alterations in natural resistance mediated by natural killer cells and macrophages; development of specific immunity mediated by T-lymphocytes or antibodies; modulation of tumor-associated antigen expression; and the down-regulation of the immune response to the tumor by several suppressor mechanisms; the augmentation of the immune response and its potential for therapeutic application; includes the prophylaxis of metastases formation by NK cells; the therapy of metastases by augmentation NK-, macrophage-, or T-lymphocyte-mediated responses by biological response modifiers; and the transfer of anticancer activity by cytoxic T-lymphocytes or immunoconjugates of monoclonal antibodies with specificity for tumors

    One hundred and thirty five patients with carcinoma of the nasopharynx were treated by radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University between August 1977 and July 1987. Of the 30 patients omitted: 8 had distant metastases at initial diagnosis or during radiotherapy; 18 patients refused or did not received a full course of radiation therapy, and four had not been confirmed histologically. The remaining 105 patients were analyzed to determine the incidence and patter of distant metastases. Diagnosis of distant metastases was made based on clinical signs and radiography, even though histologic confirmation was not made. Twenty-six patients developed distant metastases after definite irradiation of nasopharynx and neck, an incidence rate of 24.8%. The common sites of distant metastases were, in descending order, bone, lung, liver, and brain. There was a strong correlation between Ho's N stage and distant metastases rate. But sex, age, histologic subtype (squamous cell and undifferentiated cell), AJC T and N stage, treatment modalities (radiotherapy alone and radiotherapy combined with chemotherapy) were not significant. Of those patients who developed distant metastases, 80.8% were discovered within 2 years of their radical radiotherapy. The prognosis for nasopharyngeal carcinoma patients developing distant metastases was poor: median survival was nine months and 80% of those patients died within two years of the initial diagnosis of distant metastasis

    Purpose: Stereotactic radiosurgery is an alternative option to neurosurgical excision in the management of patients with brain metastases. We retrospectively analyzed patients with brain metastases of malignant melanoma who were treated at our institution for outcome and prognostic factors. Patients and Methods: 64 patients with 122 cerebral metastases were treated with stereotactic radiosurgery between 1986 and 2000. Twelve patients (19%) showed neurologic symptoms at the time of treatment, and 46 patients (72%) had extracerebral tumor manifestation at that time. The median dose to the 80% isodose line, prescribed to encompass the tumor margin, was 20 Gy (range, 15-22 Gy). Results: Neurologic symptoms improved in five of twelve symptomatic patients. 41 patients remained asymptomatic or unchanged in their neurologic symptoms. Only five patients (8%) temporarily worsened neurologically after therapy despite no signs of tumor progression. With a mean follow-up time of 9.4 months, actuarial local control was 81% after 1 year. There was a statistically significant dose and size dependency of local tumor control. Median actuarial survival after treatment was 10.6 months. Patients without extracerebral tumor manifestation showed a superior survival (p = 0.04). Conclusions: Despite high local tumor control rates, the prognosis of patients with cerebral metastases of malignant melanoma remains poor. Stereotactic radiosurgery has the potential of stabilizing or improving neurologic symptoms in these patients in a palliative setting. (orig.)

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

    Full Text Available IntroductionThe aim of the present study was to compare the therapeutic efficacy of 153Sm-EDTMP and 177Lu-EDTMP in pain palliation in cancer patients with skeletal metastases.Materials and methodsThirty patients (25 M:5 F, mean age: 66.0 ± 14.7 years of breast/prostate cancer with documented skeletal metastases were recruited prospectively. Twenty patients were considered randomly for treatment with 153Sm-EDTMP and with 177Lu-EDTMP in 10 patients, respectively. Using fixed dose of 37.0 MBq/kg body weight of each, the mean administered doses of 153Sm-EDTMP and 177Lu-EDTMP were 2,155.2 ± 419.6 MBq (1,347–2,857 and 1,935.1 ± 559.4 MBq (1,073–2,627, respectively. Anterior and posterior whole body images were acquired at different time points following radioactivity administration. The first data set of pre-void images (acquired at 0.5 h representing the total activity of either of 153Sm-EDTMP or 177Lu-EDTMP was considered as reference images. All the serial images were used for patients’ dosimetry analysis by using organ level internal dosimetry assessment algorithm. Reduction in pain scoring was assessed clinically over 8 weeks by using appropriate WHO criteria and correlated with the absorbed dose to the metastatic sites.ResultsA total of 86 metastatic lesions clearly visualized on post-therapy serial images (matching on bone scans were evaluated for absorbed dose calculations. Both 153Sm-EDTMP and 177Lu-EDTMP delivered similar absorbed dose to the metastatic sites, i.e., 6.22 ± 4.21 and 6.92 ± 3.92 mSv/MBq, respectively. The mean absorbed doses to various other organs were found to be comparable and within the safe limits. A complete response (CR for each radionuclide was evaluated as 80.0%. No significant alternation in blood parameters and no untoward reaction were observed. However, a mild to severe toxicity was observed in two patients (1 each with 153Sm-EDTMP and 177Lu-EDTMP.

    The element radium (Ra) was discovered by the Curies in 1898 and within a decade was in broad scientific testing for the management of several forms of cancer. The compound was known to give rise to a series of both high-energy particulate and penetrating γ-emissions. The latter found an important role in early 20th century brachytherapy applications, but the short-range α-particles seemed much less useful. Although highly cytotoxic when released within a few cell diameters of critical cell nuclei, the dense double-strand break damage was poorly repaired, and concerns regarding treatment-related toxicities and secondary malignancies halted clinical development. Moreover, the most common isotope of Ra has an exceptionally long half-life (>1600 years for {sup 226}Ra) that proved daunting when aiming for a systemic cancer therapy. Fortunately, other radium isotopes have more convenient half-lives while still producing cytotoxic α particles. Radium-223 dichloride has a half-life of 11.4 days, and this isotope was identified as an excellent candidate for radionuclide therapy of cancers metastatic to bone. The calcium-mimetic chemical properties of the radium allowed intravenous infusion with rapid uptake to sites of new bone formation. The highly efficient bone localization suggested a potential therapeutic role for osteoblastic bone metastases, and a series of phase 1, 2, and 3 clinical trials was undertaken to explore this possibility. This series of clinical explorations culminated in the ALSYMPCA trial, an international, placebo-controlled, phase 3 study that accrued 921 symptomatic men with bone-metastatic, castrate-resistant prostate cancer. Results of this trial demonstrated a prolongation of overall survival, and regulatory agencies around the world have now approved this product as a treatment for advanced prostate cancer.

    The results of treatment of hepatic metastases secondary to carcinoma of the breast, bronchus and gastrointestinal tract, are reported in 36 patients; asymptomatic improvement was obtained in 26 patients. The symptomatic relief of pain, anorexia, nausea, vomiting, weakness, fatigue, sweating and abdominal distention was accompanied by reduction in the size of the enlarged liver, by gain in body weight, and by improvement in liver function as measured by determination of the serum bilirubin, alkaline phosphatase, cholesterols and proteins, and by the bromsulphalein retention test, the prothrombin time, the cephalin flocculation test and the thymol turbidity. The method of treatment was supervoltage roentgen therapy alone in 22 cases; in 14 cases a single intravenous dose of nitrogen mustard (0.4 mg. per kilogram body weight) was given immediately before the first roentgen treatment. The whole liver, however large, was irradiated through opposed anterior and posterior fields, and the tumor dose ranged from 2,000 to 3,750 roentgens. The over-all time of treatment was eight days in 24 cases, fifteen days in 6 cases, and twenty-two days in 6 cases

    Full Text Available Background. The aim of this study was to show the importance of the bone marker procollagen type 1 aminoterminal propeptide (P1NP in detecting bone metastases in women suffering from breast cancer. We furthermore investigated to what degree P1NP is correlated to the degree of bone metastases, and if P1NP is increased in patients with metastases other than bone. Patients and Methods. We analyzed 80 serum samples of women (17 premenopausal/63 postmenopausal with breast cancer. Therefore we used a specific immunoassay “ELECSYS 2010” by Roche Diagnostics. We divided our group of patients with regard to menopausal status, sites of metastases and number of bone metastases. Results. As a result we found higher concentrations of P1NP in women with radiologically confirmed bone metastases (median: 125.75 ng/mL in comparison to the collective without bone involvement (median: 73.61 ng/mL. However, both groups showed values above the applied cutoff values of median 27.8 ng/mL for premenopausal women and median: 37.1 ng/mL for the postmenopausal group due to the fact that all patients had cancer. Furthermore higher P1NP concentrations were found in women with more than 5 sites of bone metastases (median: 183.9 ng/mL than in patients with only one site of bone metastases (median: 37 ng/mL. Also patients with no bone involvement but other sites of metastases showed quite high P1NP concentrations (median: 73.61 ng/mL. Conclusion. The marker of bone turnover procollagen type 1 aminoterminal propeptide can be considered as a useful tool for estimating the extent of bone involvement and for the detection of bone metastases. P1NP cannot replace conventional methods for detecting bone metastases such as radiological methods but it can help clarify unclear radiological results. This study does not take into account the change of P1NP concentration during the course of therapy.

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

    Extraneural metastases from CNS medulloblastoma are rare and poorly described. The purpose of this study is to describe the clinical and radiological characteristics of a large single institution series of patients with medulloblastoma who developed extraneural metastases. We retrospectively reviewed a departmental database over a 20 year period for all patients with medulloblastoma who developed extraneural metastases. Chart and imaging reviews were performed, and overall survival (OS) estimated by the Kaplan-Meier method. We found 14 patients with medulloblastoma and extraneural metastases. The median age at initial diagnosis was 16.3 years (range, 3.2-44.2), and the most common subtype was desmoplastic (n = 6, 42.9%). After initial gross total resection, most patients received radiation therapy alone (n = 10, 71.4%). Metastases to bone were most common (n = 11, 78.6%) followed by metastases to bone marrow (n = 6, 42.9%), usually to the spine. The median time from initial diagnosis to first extraneural metastasis was 1.5 years (range, 0.2-17.4), and the median OS from extraneural metastasis to death was 3.3 years (range, 0-18). The Kaplan-Meier estimate of 5 year OS from extraneural metastasis diagnosis was 40.0% (95% CI, 20.2-79.2). Extraneural metastases from medulloblastoma may rarely develop after initial diagnosis to involve bone and bone marrow. We found that desmoplastic variant extraneural tumors had longer survival than nondesmoplastic variants, suggesting that histopathological and more recent molecular subtyping have important roles in determining the prognosis of medulloblastoma patients. © 2014 Wiley Periodicals, Inc.

    Malignant gliomas account for approximately 60% of all primary brain tumors in adults. Prognosis for these patients has not significantly changed in recent years— despite debulking surgery, radiotherapy and cytotoxic chemotherapy—with a median survival of 9–12 months. Virtually no patients are cured of their illness. Malignant gliomas are usually locally invasive tumors, though extra-neural metastases can sometimes occur late in the course of the disease (median of two years). They generally appear after craniotomy although spontaneous metastases have also been reported. The incidence of these metastases from primary intra-cranial malignant gliomas is low; it is estimated at less than 2% of all cases. Extra-neural metastases from gliomas frequently occur late in the course of the disease (median of two years), and generally appear after craniotomy, but spontaneous metastases have also been reported. Malignant glioma metastases usually involve the regional lymph nodes, lungs and pleural cavity, and occasionally the bone and liver. In this review, we present three cases of extra-neural metastasis of malignant gliomas from our department, summarize the main reported cases in literature, and try to understand the mechanisms underlying these systemic metastases.

    Distant metastases in differentiated thyroid cancer involve mainly lung and bone. Lung metastases were found in 5% of papillary forms and 10% of follicular forms respectively. I 131 uptake was found in 55% of the cases irrespective of histology. Bone metastases were found in 20% of follicular and 3.5% of papillary forms, respectively. Ablation of post-operative thyroid remnants is obtained by administering 3.7 GBq I 131; I 131 (.2 to .4 GBq) is then used to localize distant metastases and a further 3.7 to 7.4 GBq is administered for therapy. Results are good in lung metastases, with a survival of 72% at 5 years. Bone metastases cannot be cured with I 131 alone. Surgery is indicated as a first line therapy if possible. In order to reduce the vascularization of the metastases a pre-operative embolization should be attempted. After bone surgery a therapeutic dose of I 131 is given if a post-operative I 131 uptake is found. Others treatments of bone metastases are palliative surgery, external radiotherapy, cementing of the metastases. (author). 6 refs.

    : Intracranial dural metastases (IDM) are found at autopsy in 9% of patients with advanced systemic cancer. However, to the authors' knowledge, IDM have not been studied systematically in the modern neuroimaging era. The objective of the current study was to evaluate the demographics, clinical presentation, imaging, treatment, and prognosis of patients with IDM. : The current study was a retrospective review of 122 patients with IDM diagnosed at Memorial Sloan-Kettering Cancer Center between 1999 and 2006. Patients with concurrent brain or leptomeningeal metastases were excluded. : Sixty-one percent of the patients were women; the median age at diagnosis was 59 years, the median Karnofsky performance scale (KPS) at diagnosis was 80, and the median time to IDM diagnosis from initial cancer diagnosis was 37 months. Breast (34%) and prostate (17%) cancers were the most frequent primary tumors associated with IDM. Fifty-six percent of patients had a single dural metastasis. On imaging, 70% had metastases of the overlying skull, 44% had dural tail metastases, 53% had vasogenic edema, and 34% had brain invasion. Direct extension from skull metastases was the most common mode of spread. Eighty-three percent of patients had active systemic disease at the time of IDM diagnosis. A lower KPS and lung cancer were associated with worse overall survival. Surgical resection and chemotherapy improved progression-free survival, but only resection was found to be associated with improved overall survival. : IDM affect a significant proportion of cancer patients. KPS and status of systemic cancer should guide treatment decisions. Cancer 2009. (c) 2009 American Cancer Society.

    2017-04-01

    Brain metastases are the most common intracranial tumors in adults. Historically, the median survival after the diagnosis of brain metastases has been dismal and medical therapies had a limited role in the management of these patients. The advent of targeted therapy has ushered in an era of increased hope for patients with brain metastases. The most common malignancies that result in brain metastases-melanoma, lung cancer, and breast cancer, often have actionable mutations, which make them good candidates for targeted systemic therapy. These brain metastases have been shown to have relevant and sometimes divergent genetic alterations, and there has been a resurgence of interest in targeted drug delivery to the brain by using standard or pulsatile dosing to achieve adequate concentration in the brain. An increased understanding of oncogenic alterations, a surge in targeted drug development with good blood barrier penetration, and inclusion of patients with active brain metastases on clinical trials have led to improved outcomes for patients with brain metastases.

    Tumor hemorrhage on computed tomography (CT) was found in 14 patients with brain metastases (7 % of two hundred patients with brain metastases), from April 1979 to July 1983. Primary foci of these lesions were the lung (6 patients), breast (2), kidney (2), uterus (2), colon (1) and adrenal gland (1). ''Stroke'' syndrome was the initial presenting symptom in 3 patients; neurological focal sign or symptoms of increased intracranial pressure in the remaining patients. CT demonstrated peritumoral hemorrhage in all patients with solid mass, intratumoral hemorrhage in a few patients and also cerebral or ventricular hemorrhage, which was fatal complication, in 2 patients (colon and breast cancers). A cystic mass with fluid-blood level was noted in a patient with breast cancer. Several predisposing factors including chemotherapy, thrombocytopenia, radiotherapy or combination of these were recognized in 8 patients. Of these, chemotherapy was the most causative factor of tumor hemorrhage. Brain irradiation for hemorrhagic brain metastases was effective for prolongation of mean survival time of these patients as follows; 10 months in irradiated group, whereas 1.5 months in non-irradiated group.

    The diagnosis of intravascular metastatic tumor emboli to the lungs is rarely made. The authors present a characteristic radiographic finding of intravascular lung metastases that they observed in four patients with diagnoses or right atrial myoxoma, invasive renal cell carcinoma, invasive pelvic osteosarcoma, and recurrent pelvic chondrosarcoma. Substantiation of intravascular pulmonary metastases was achieved by means of autopsy, pulmonary artery biopsy, and surgical documentation of tumor invasion of the inferior vena cava or pelvic veins. In all four cases, chest computed tomography (CT) demonstrated branching, beaded opacities extending from the hila into the periphery of the lung in the distribution of pulmonary arteries. In one case, similar findings were observed in magnetic resonance (MR) images of the chest. Follow-up studies in three cases showed progressive enlargement and varicosity of the abnormal pulmonary artery consistent with proliferation of intravascular tumor. In the case of metastatic osteosarcoma, intraluminal ossification was also observed at CT. In three of four cases, pulmonary infarction was demonstrated in the distribution of the abnormal pulmonary arteries seen at CT as small, peripheral, wedge-shaped opacities. The demonstration of progressively dilated and beaded pulmonary arteries in patients with extrathoracic malignancies is suggestive of intravascular lung metastases, particularly when accompanied by peripheral infarction

    Standard radiotherapy is the treatment of first choice in patients with symptomatic spinal metastases, but is only moderately effective. Stereotactic body radiation therapy is increasingly used to treat spinal metastases, without randomized evidence of superiority over standard radiotherapy. The VERTICAL study aims to quantify the effect of stereotactic radiation therapy in patients with metastatic spinal disease. This study follows the ‘cohort multiple Randomized Controlled Trial’ design. The VERTICAL study is conducted within the PRESENT cohort. In PRESENT, all patients with bone metastases referred for radiation therapy are enrolled. For each patient, clinical and patient-reported outcomes are captured at baseline and at regular intervals during follow-up. In addition, patients give informed consent to be offered experimental interventions. Within PRESENT, 110 patients are identified as a sub cohort of eligible patients (i.e. patients with unirradiated painful, mechanically stable spinal metastases who are able to undergo stereotactic radiation therapy). After a protocol amendment, also patients with non-spinal bony metastases are eligible. From the sub cohort, a random selection of patients is offered stereotactic radiation therapy (n = 55), which patients may accept or refuse. Only patients accepting stereotactic radiation therapy sign informed consent for the VERTICAL trial. Non-selected patients (n = 55) receive standard radiotherapy, and are not aware of them serving as controls. Primary endpoint is pain response after three months. Data will be analyzed by intention to treat, complemented by instrumental variable analysis in case of substantial refusal of the stereotactic radiation therapy in the intervention arm. This study is designed to quantify the treatment response after (stereotactic) radiation therapy in patients with symptomatic spinal metastases. This is the first randomized study in palliative care following the cohort multiple Randomized

    Metastases are the most frequent malignant tumors of the kidney, but these lesions are of late onset in neoplastic disease. The 19 cases reported here were all investigated with various imaging techniques (CT 12 cases, ultrasonography 12 cases, urography 8 cases, angiography 2 cases, MRI 1 case). The most common primary malignancies were lung cancer, melanoma and cancer of the controlateral kidney. In this series, 8 of the lesions were solitary, and 9 were unilateral. Tumor vascularity was evaluated in 15 cases: 14 of these lesions were hypovascular. The differential diagnosis includes small cysts, lymphoma, bilateral renal cancer, multiple small abscesses and multiple small infarcts [fr

    Full Text Available Medulloblastoma is the most common childhood malignant tumor of central nervous system, but it may also occur in adults. It presents high invasive growth with spreading of tumor cells into the leptomeningeal space along the neuroaxis early in the course of the disease. Extraneural metastases are rare but frequently lethal, occurring only in 1 to 5% of patients, and are related, in the most of cases, to the presence of ventriculoperitoneal shunt. Here we characterize the clinical profile of five cases of medulloblastoma with systemic spreading of tumor cells, also comparing them to cases already described in the literature.

    Full Text Available Abstract Background Minimally invasive vertebral augmentation procedures are widely used to treat vertebral compression fractures although procedural polymethylmethacrylate cement leakage remains common. We report herein our initial experience with a novel vertebral augmentation technique designed to treat symptomatic vertebral osteoporotic fractures and osteolytic metastases with minimal cement extravasation. Methods Forty-two vertebral fractures were identified in 26 consecutive patients (mean age 74 ± 9 years. All patients were treated with a novel percutaneous vertebral augmentation device (Kiva® VCF Treatment System, Benvenue Medical, Santa Clara, CA, USA. Indications for surgery included recent (≤ 3 months symptomatic osteoporotic vertebral fracture (n = 34 and pathologic vertebral fractures (e.g. metabolic bone disease, myeloma, metastasis (n = 8 located between T10 and S1. Patient outcomes were evaluated pre-treatment and at 2- and 6-month follow-up visits. Postoperative cement extravasation was assessed with computed tomography. Patient-reported back pain was quantified using an 11-point numeric scale. Back-specific functional disability was self-reported with the Oswestry Disability Index on a 0 to 100% scale. Results No cases of intraoperative hypotension, respiratory disturbance, neurological deterioration, infection, or death were observed. There were 2 (4.8% levels where anterior cement leakage was visible radiographically in patients with osteolyses. No intracanal leakage was observed. Back pain scores improved 71% (p Conclusions The initial clinical experience with the Kiva® System demonstrated significant improvements in back pain and function with minimal and clinically insignificant procedural cement leakage.

    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.

    Full text: Measurement Thyroglobulin (Tg), an iodo-protein specific to the thyroid gland, is very useful to study the pathogenesis, establish the diagnosis and follow the course of thyroid disorders. In thyroid cancer, Tg is a valuable tumor marker for diagnosing, as well as for following-up and evaluating the status of thyroid cancer after surgical and radioiodine therapy. We retrospectively analysed the relation of serum thyroglobulin concentration and the post-surgical status of thyroid in patients with papillary or follicular thyroid cancer. 321 patients who underwent thyroidectomy due to thyroid cancer were included in this study. They were divided into groups such as group-1 (no metastases), group-2 (neck lymph node metastases) and group-3 (distant metastases) as well as subgroup of lung, bone and combined lung and bone metastases. All the patients were asked to stop T4 for 6 weeks and T3 for 2 weeks before performing a whole body scan with 2 mCi of radioiodine-131. Radioimmuno-assay measurement of FT3, FT4, TSH, serum thyroglobulin (Tg) and serum anti-thyroglobulin antibody (TgAb) was also done. Mean serum Tg concentration in patients with follicular cancer was higher than that of papillary but there was not statistically significant difference (p>0.05). However, there was a significant difference in mean serum Tg concentration between distal metastases group and no metastases group as well as neck lymph node metastases group (p 0.05). In general, serum Tg concentration was proportionate to the amount of functional thyroid tissue remaining in the neck or metastatic sites in the body. Although conventional diagnostic methods such as ultrasound, X-ray, bone scan were helpful to detect and evaluate the progression of thyroid cancer, but were poor indicators for detecting micro-metastases in early stage. Therefore, it is very important to combine the above-mentioned method with serum Tg measurements. In conclusion serum thyroglobulin measurement was really

    Abhimanyu Ghose MD

    2014-04-01

    Full Text Available Background. Medulloblastoma, although the most common brain tumor of childhood, is exceedingly rare in adults. These tumors have a propensity for local recurrence and to metastasize along the leptomeninges; however, extraneural metastases are very rare and typically occur in the bone or bone marrow. We have not come across any case in literature of medulloblastoma with mediastinal metastases in an adult. Case Presentation. We report a case of medulloblastoma in a 38-year-old lady who was treated with surgery followed by craniospinal radiation. Ten years later she presented with hoarseness from true vocal cord paralysis. She was diagnosed to have infiltrating metastases of her medulloblastoma to the mediastinum, which was confirmed by biopsy. There was no local recurrence. This was treated with chemotherapy followed by stem cell rescue, and she remained progression free for 2 years. Conclusion. Medulloblastomas are rare in adults and can present with late extraneural metastases following treatment. Although most common reported sites are bone and bone marrow, late metastases to other unexpected areas like the mediastinum are possible too and warrant awareness. This can be treated with chemotherapy followed by high-dose chemotherapy and stem cell rescue in a young patient with good performance status.

  7. A short account of metastatic bone disease

    Directory of Open Access Journals (Sweden)

    Lemmer Johan

    2011-07-01

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

    2010-01-01

    Purpose: The aim of the study is to evaluate disease-free survival, survival from the detection of brain metastases, overall survival, and cause of death in patients with occult brain metastases (Group I) vs. patients with symptomatic brain metastases (Group II). Methods and Materials: In 80 HER2-positive breast cancer patients, treated with trastuzumab and cytostatic agents for metastatic disease, magnetic resonance imaging screening of the brain was performed, and in 29 patients (36%) occult brain metastasis was detected (Group I). Whole-brain radiotherapy was delivered to Group I. This first group was compared with 52 patients who had symptomatic brain metastases (Group II) and was treated the same way, at the same clinic, during the same time period. Results: Median disease-free survival was 17 months in Group I and 19.9 months in Group II (p = 0.58). The median time interval between the dissemination of the disease and the detection of occult or symptomatic brain metastases was 9 and 15 months, respectively (p = 0.11). When the brain metastases were detected, the median survival was 9 and 8.78 months, respectively (p = 0.80). The median overall survival was 53 and 51 months, respectively (p = 0.94). In the group with occult brain metastases (Group I) 16% of patients died because of progression within the brain. In the group with symptomatic brain metastases (Group II) the rate of cerebral death was 48% (p = 0.009). Conclusions: Whole-brain radiotherapy of occult brain metastases in HER2-positive breast cancer patients with visceral dissemination produces a three-fold decrease in cerebral deaths but does not prolong survival.

    The prognosis of patients diagnosed with metastatic prostate cancer seems to be modulated by factors such as the number and site of metastases. Our objective is to evaluate survival outcomes according to the number and site of metastases in our series of metastatic patients over the last 15 years. A retrospective analysis was performed on patients diagnosed between 1998 and 2014. We analyzed overall survival and progression-free survival, depending on the number and location of metastases on patients with newly diagnosed metastatic prostate cancer. Other potential prognostic factors were also evaluated: age, clinical stage, PSA at diagnosis, Gleason, PSA nadir, time till PSA nadir and first-line or second-line treatment after progression. We analyzed a series of 162 patients. The mean age was 72.7yr (SD: 8.5). The estimated median overall survival was 3.9 yr (95% CI 2.6-5.2). The overall survival in patients with only lymph node metastases was 7 yr (95% CI 4.1-9.7), 3.9 (95%CI 2.3-5.5) in patients with only bone metastases, 2.5 yr (95% CI 2-2.3) in lymph nodes and bone metastases, and 2.2 yr (95% CI 1.4-3) in patients with visceral metastases (Pnumber of metastases showed no association with survival. The site of metastases has a clear impact on both overall survival and progression-free survival. Patients with only lymph node involvement had a better prognosis. The number of metastases showed no significant impact on survival in our series. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    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).

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

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

    Primary liver tumours and liver metastases from colorectal carcinoma are the two most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the patients with metastatic liver disease will die from metastatic complications. In cryoablation, liquid nitrogen or argon gas is delivered to the liver tumour, guided by ultrasound using a specially designed probe. Ice crystal formation during the rapid freezing process causes destruction of cellular structure and kills the tumour cells. To study the beneficial and harmful effects of cryotherapy compared with no intervention, other ablation methods, or systemic treatments in patients with liver metastases. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, and CINAHL up to December 2012. We included all randomised clinical trials assessing the beneficial and harmful effects of cryotherapy and its comparators, irrespective of the location of the primary tumour. We extracted relevant information on participant characteristics, interventions, study outcomes, and data on the outcomes for our review, as well as information on the design and methodology of the trials. Bias risk assessment of and data extraction from the trials fulfilling the inclusion criteria were done by one author and checked by a second author. One randomised clinical trial fulfilled the inclusion criteria of the review. The trial was judged as a trial with high risk of bias due to the unclear report on the generation of the allocation sequence and allocation concealment, blinding, incomplete outcome data and the selective outcome reporting domain. The trial included 123 consecutive patients with solitary or multiple unilobar or bilobar liver metastases who were randomised into two groups, 63

    Extra-axial intracranial metastases may arise through several situations. Hematogenous spread to the meninges is the most frequent cause. Direct extension from contiguous extra-cranial neoplasms, secondary invasion of the meninges by calvarium and skull base metastases, and migration along perineural or perivascular structures are less common. Leptomeningeal invasion gives rise to tumour cell dissemination by the cerebrospinal fluid (CSF), eventually leading to neoplastic coating of brain surfaces. Contrast-enhanced magnetic resonance (MR) imaging is complementary to CSF examinations and can be invaluable, detecting up to 50% of false-negative lumbar punctures. MR findings range from diffuse linear leptomeningeal enhancement to multiple enhancing extra-axial nodules, obstructive communicating and non-communicating hydrocephalus. Both calvarial and epidural metastases infrequently transgress the dura, which acts as a barrier against tumour spread. Radionuclide bone studies are still a valuable screening test to detect bone metastases. With computed tomography (CT) and MR, bone metastases extending intracranially and primary dural metastases show the characteristic biconvex shape, usually associated with brain displacement away from the inner table. Although CT is better in detecting skull base erosion, MR is more sensitive and provides more detailed information about dural involvement. Perineural and perivascular spread from head and neck neoplasms require thin-section contrast-enhanced MR.

    2011-01-01

    This paper will focus on knowledge related to brain metastases from ovarian carcinoma. So far, less than 600 cases were documented in the literature with an incidence among ovarian carcinoma patients ranging from 0.29% to 11.6%. The ovarian carcinoma was usually an advanced-stage epithelial serous carcinoma, and the median interval between diagnosis of ovarian carcinoma and brain metastases was 2 years. Most often, brain metastases, affected the cerebrum, were multiple and part of a disseminated disease. Treatment of brain metastasis has evolved over the years from whole brain radiotherapy (WBRT) only to multimodal therapy including surgical resection or stereotactic radiosurgery followed by WBRT and/or chemotherapy. The median survival after diagnosis of brain metastases was 6 months; nevertheless, a significantly better survival was achieved with multimodal therapy compared to WBRT only. It is suggested that brain imaging studies should be included in the followup of patients after treatment for ovarian carcinoma. PMID:22191058

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

    A number of different methods have been proposed for pain relief in cancer patients with bone metastases, each with different indications, contraindications and complications (systemic analgesics, bisphosphonates, antitumor chemotherapy, radiotherapy, systemic radio-isotopes, local surgery and vertebroplasty). The ideal treatment has to be fast, safe, effective and tolerable for the patient. CT-guided radiofrequency (RF) ablation may fulfill these criteria. Our experience in the treatment of 30 patients (34 lesions) with painful bone metastases using RF ablation was assessed. There was a significant decrease in the mean past-24-h Brief Pain Inventory (BPI) score for worst pain, for average pain and for pain interference during daily life (4.7, 4.8 and 5.3 units respectively) 4 and 8 weeks after treatment. There was a marked decrease (3 out of 30 patients 4 and 8 weeks after treatment) in the use of analgesics. CT-guided RF ablation appears to be effective for treatment of painful bone metastases.

    Although systematic vitamin D supplementation in adolescents remains debated, rickets is nevertheless a well recognized pathology in this age group. Adolescence is an at-risk period because of rapid growth, insufficient calcium intake and/or vitamin D status. Surveys have shown that calcium intake is insufficient (population at risk. Forty-one adolescents with rickets were hospitalized between 1985 and 2000. Most of the cases were from the Northern France: 20 from Paris and suburbs, eight from the North-West, four from the North, four from the North-East; five were from the Center of France. The mean age was 13 years and two months for the 28 girls, and 14 years and four months for the 13 boys. Eighty per cent of the adolescents were from immigrant families (33/41): 15 were from sub-Saharan Africa, ten from North Africa, six from Pakistan and two from Turkey. Two thirds of the adolescents were hospitalized in the 2nd quarter of the year. Some adolescents suffered from lower limb pain, 16 had deformations of lower limbs, particularly genu valgum, associated with pain; seven others had either muscle spasms (4), tetany (3). Serum calcium level was low (average 1.84 mmol/l: [1.1-2.5]), and serum 25-OH D level was extremely low. Radiographic characteristics observed were metaphyseal strips on the knees, with condensed edges at times, with the presence of bone demineralization. The treatment combined calcium and vitamin D, and was often administered intravenously when a hypocalcemia was detected. Rickets is not frequent in adolescents, but nonetheless this pathology is not exceptional, and the number of cases is probably under-estimated. Rickets affects immigrant adolescents in particular but nevertheless could also present a certain risk period for the general population.

    Full Text Available Metastasis to the brain is a feared complication of systemic cancer, associated with significant morbidity and poor prognosis. A better understanding of the tumor metabolism might help us meet the challenges in controlling brain metastases. The study aims to characterize the metabolic profile of brain metastases of different origin using high resolution magic angle spinning (HR-MAS magnetic resonance spectroscopy (MRS to correlate the metabolic profiles to clinical and pathological information. Biopsy samples of human brain metastases (n = 49 were investigated. A significant correlation between lipid signals and necrosis in brain metastases was observed (p < 0.01, irrespective of their primary origin. The principal component analysis (PCA showed that brain metastases from malignant melanomas cluster together, while lung carcinomas were metabolically heterogeneous and overlap with other subtypes. Metastatic melanomas have higher amounts of glycerophosphocholine than other brain metastases. A significant correlation between microscopically visible lipid droplets estimated by Nile Red staining and MR visible lipid signals was observed in metastatic lung carcinomas (p = 0.01, indicating that the proton MR visible lipid signals arise from cytoplasmic lipid droplets. MRS-based metabolomic profiling is a useful tool for exploring the metabolic profiles of metastatic brain tumors.

    The authors describe a case of a 47-year-old male smoker with a 3-month history of hearing loss, tinnitus and dizziness. Physical examination revealed neurosensory hearing loss. Small rounded hypodensities without mass effect were evident in a computed tomography scan of the head, confirmed by brain magnetic resonance imaging as multiple cystic lesions in both cerebral and cerebellar hemispheres, without perilesional edema or gadolinium enhancement, suggestive of neurocysticercosis. Extraparenchymal involvement was also noted. Albendazole and dexamethasone were started. As a chest radiograph showed a bilateral reticulonodular pattern, a bronchoscopy was performed showing normal results. However, transbronchial biopsy revealed lung adenocarcinoma. Thoracoabdominopelvic computed tomography scan showed secondary lung and bone lesions. Since brain lesions were not suggestive of secondary tumor lesions, a brain biopsy was performed confirming metastatic disease. This case illustrates some peculiar imagiological features of brain metastases in lung cancer, indicating that sometimes invasive procedures are required to establish a definitive diagnosis.

    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...

    radiation related changes. One patient had symptoms of dementia that was thought to be caused by radiotherapy. Various potential prognostic factors were evaluated for possible associations with survival, including age, sex, primary site, tumor histology, performance status, neurological function class, presence of extracranial metastases, number of brain metastases, and the dose of reirradiation. Patients with solitary brain metastasis survived significantly longer than those with multiple brain metastases (median survival = 5.75 vs 3.5 months, p = 0.03 [log rank test]). Patients receiving more than 20 Gy at reirradiation also appeared to survive longer than those who received lower doses (median survival = 4.5 vs 3.5 months [log-rank test: p<0.06, Wilcoxon test: p<0.033]). Conclusion: This represents the largest published series of patients reirradiated for brain metastases. The median survival of 4 months after reirradiation is comparable to most series when patients were treated with WBRT after initial diagnosis of brain metastases. The majority of patients in our series had favorable symptomatic responses. Clinically significant complications are minimal. Reirradiation should be offered to patients who develop progressive brain metastases. Doses of greater than 20 Gy may provide a better outcome than lower doses

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

    Stereotactic radiosurgery (SRS) is frequently used in the management of brain metastases, but concerns over potential toxicity limit applications for larger lesions or those in eloquent areas. Fractionated stereotactic radiation therapy (SRT) is often substituted for SRS in these cases. We retrospectively analyzed the efficacy and toxicity outcomes of patients who received SRT at our institution. Seventy patients with brain metastases treated with SRT from 2006-2012 were analyzed. The rates of local and distant intracranial progression, overall survival, acute toxicity, and radionecrosis were determined. The SRT regimen was 25 Gy in 5 fractions among 87 % of patients. The most common tumor histologies were non-small cell lung cancer (37 %), breast cancer (20 %) and melanoma (20 %), and the median tumor diameter was 1.7 cm (range 0.4-6.4 cm). Median survival after SRT was 10.7 months. Median time to local progression was 17 months, with a local control rate of 68 % at 6 months and 56 % at 1 year. Acute toxicity was seen in 11 patients (16 %), mostly grade 1 or 2 with the most common symptom being mild headache. Symptomatic radiation-induced treatment change was seen on follow-up MRIs in three patients (4.3 %). SRT appears to be a safe and reasonably effective technique to treat brain metastases deemed less suitable for SRS, though dose intensification strategies may further improve local control.

  6. Correlation Between Bone Scintigraphy and Tumor Markers in Patients with Breast Carcinoma

    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.

    Bone scans or skeletal surveys were obtained in 104 patients with ovarian carcinoma. No metastases were identified at staging in the 43 patients with Stage I or II disease. Four patients in the entire series had osseous metastases. Three of the 40 patients with Stage III epithelian ovarian carcinoma has osseous metastases at the time of staging. All of these were Grade III lesions. One Stage I, Grade III patient demonstrated osseous metastases two years after initial diagnosis. None of the four patients with osseous metastases had an elevated alkaline phosphatase; three of the four had bone pain. Based on these results, it is suggested that radiographic bone survey and radionuclide bone scans are not indicated as screening procedures in asymptomatic patients with ovarian carcinoma

    Aim of this single center, retrospective study was to assess the efficacy and safety of linear accelerator-based hypofractionated stereotactic radiotherapy (HFSRT) to the resection cavity of brain metastases after surgical resection. Local control (LC), locoregional control (LRC = new brain metastases outside of the treatment volume), overall survival (OS) as well as acute and late toxicity were evaluated. 46 patients with large (> 3 cm) or symptomatic brain metastases were treated with HFSRT. Median resection cavity volume was 14.16 cm 3 (range 1.44-38.68 cm 3 ) and median planning target volume (PTV) was 26.19 cm 3 (range 3.45-63.97 cm 3 ). Patients were treated with 35 Gy in 7 fractions prescribed to the 95-100 % isodose line in a stereotactic treatment setup. LC and LRC were assessed by follow-up magnetic resonance imaging. The 1-year LC rate was 88 % and LRC was 48 %; 57% of all patients showed cranial progression after HFSRT (4% local, 44% locoregional, 9% local and locoregional). The median follow-up was 19 months; median OS for the whole cohort was 25 months. Tumor histology and recursive partitioning analysis score were significant predictors for OS. HFSRT was tolerated well without any severe acute side effects > grade 2 according to CTCAE criteria. HFSRT after surgical resection of brain metastases was tolerated well without any severe acute side effects and led to excellent LC and a favorable OS. Since more than half of the patients showed cranial progression after local irradiation of the resection cavity, close patient follow-up is warranted. A prospective evaluation in clinical trials is currently being performed. (orig.) [de

    Although skeletal muscles comprise nearly 50% of the total human body mass and are well vascularised, metastases in the musculature are rare. The reported prevalence of skeletal muscle metastases from post-mortem studies of patients with cancer is inconstant and ranges from 0.03 to 17.5%. Of 5,170 patients with metastasised cancer examined and treated at our institution during the period from January 2000 to December 2007, 61 patients with muscle metastases (80 lesions) were identified on computed tomography (CT). Genital tumours (24.6%) were the most frequent malignancies metastasising into the skeletal musculature, followed by gastrointestinal tumours (21.3%), urological tumours (16.4%), and malignant melanoma (13.1%). Other primary malignancies were rarer, including bronchial carcinoma (8.2%), thyroid gland carcinoma (4.9%), and breast carcinoma (3.3%). In 8.2%, carcinoma of unknown primary was diagnosed. Skeletal muscle metastases (SMM) were located in the iliopsoas muscle (27.5%), paravertebral muscles (25%), gluteal muscles (16.3%), lower extremity muscles (12.5%), abdominal wall muscles (10%), thoracic wall muscles (5%), and upper extremity muscles (3.8%). Most (76.3%) of the 80 SMM were diagnosed incidentally during routine staging CT examinations, while 23.7% were symptomatic. Radiologically, SMM presented with five different types of lesions: focal intramuscular masses (type I, 52.5% of SMM), abscess-like intramuscular lesions (type II, 32.5%), diffuse metastatic muscle infiltration (type III, 8.8%), multifocal intramuscular calcification (type IV, 3.7%) and intramuscular bleeding (type V, 2.5%).

    Samarium-153-EDTMP has been successfully used for pain palliation in metastatic bone cancer to a lesser extend in rheumatoid arthritis. Were studied 110 patients, 90 with metastatic bone cancer and 20 with rheumatoid arthritis. Each patient received 37 MBq/kg (1mCi/kg) of Sm-153-EDTMP, intravenously injected. Urine samples were collected during 6 hours. Blood samples were collected before and one hour after the injection. The MIRD formalism was utilized for dosimetric calculations. The absorbed dose for red marrow, cortical and trabecular for patients with rheumatoid arthritis were respectively: 206{+-}66,38 cGy; 544,04{+-}171,31 cGy; 630,80{+-}197,15 cGy. For the patients with metastatic bone cancer, the absorbed dose for red marrow was 319,07{+-}94,06 cGy, cortical 841,58{+-}236,12 cGy; trabecular 978,23{+-} 264,05 cGy. The leukocyte counts decreased 48,5%{+-}19%, the platelets 54,7%{+-}26% and hemoglobin 13,7%{+-}11%, from the baseline values. The principal kind of the structural aberrations observed were: acentric fragments, breaks, chromosomal gaps, centric ring and double minute. The number of the aberrations in blood cells, after the application of Sm-153-EDTMP, was 2,13 times bigger than the baseline. The absorbed dose radiation, the hematological and genetics effects established were in the limits accepted for this kind of treatment. (author)

    Bone tumors and especially bone sarcomas are rare lesions of the skeletal system in comparison to the much more frequently occurring bone metastases. Despite the relative rarity they are important differential diagnoses of bone lesions. The aim of this article is to give the reader an insight into the fundamentals of the primary imaging of bone sarcomas and to illustrate this with the help of two examples (e.g. osteosarcoma and chondrosarcoma). The foundation of the imaging of bone sarcomas is the radiograph in two planes. This method delivers important information on bone tumors. This information should be analyzed with the help of the Lodwick classification, the configuration of periosteal reactions and a possible reaction of the cortex. A possible tumor matrix and the localization within the skeleton or within long bones also provide important information for differential diagnostic delimitation. Magnetic resonance imaging (MRI) with specific adapted bone tumor sequences allows an exact local staging of a bone sarcoma. In addition to local imaging a compartmental MRI which illustrates the entire extent of tumor-bearing bone and the adjacent joints should be performed to rule out possible skip lesions. The most common distant metastases of osteosarcoma and chondrosarcoma occur in the lungs; therefore, a computed tomography (CT) of the chest is part of staging. Other imaging methods, such as CT of the tumor, positron emission tomography CT (PET-CT), bone scan and whole body MRI supplement the imaging depending on tumor type.

    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.

    A case of primary hemangiosarcoma of the spleen in a 48-year-old woman is presented. Twenty-eight months after splenectomy the patient developed a severe anemia of the microangiopathic type, thrombocytopenia, and a leukoerythroblastic peripheral blood picture. In contrast to x-ray and conventional /sup 99m/Tc-methylene-diphosphonate (MDP) bone scintigraphy, which showed only a few minor focal changes in the spine and ribs, angioscintigraphy with in vitro labeled /sup 99m/Tc-erythrocytes revealed extensive pathologic accumulations throughout the spine, femurs, and the liver, indicating the presence of extremely vascular metastases. Autopsy 15 months later confirmed the scintigraphic findings. Angiography with /sup 99m/Tc-labeled erythrocytes seems to be useful for monitoring metastases from hemangiosarcomas.

    Medulloblastoma is one of the most undifferentiated primitive neuroectodermal tumors and represents about 30% of all posterior fossa tumors in children. Disseminated medulloblastoma, mainly involving cerebral surfaces, ventricles and the subarachnoid space can, in 50% of patients, be identified on intial imaging studies. One third of these lesions metastasize to an extracranial sity, primarily to bone. Osseous metastases, which occur mainly after craniectomy are typically lytic, but osteoblastic lesions also may occur. We experienced the case of a 14 year-old female patient with multiple bone metastases of medulloblastoma after craniectomy. Bone metastatic lesions were present in the right femur and thoracic spine and were osteoblastic or osteolytic

    Full Text Available Abstract Colorectal cancer (CRC is the third most common cancer in the word. Liver metastasis is the most common site of colorectal metastases. The prognosis of resectable colorectal liver metastases (CRLM was improved in the recent years with the consideration of chemotherapy and surgical resection as part of the multidisciplinary management of the disease; the current 5-year survival rates after resection of liver metastases are 25% to 40%. Resectable synchronous or metachronous liver metastases should be treated with perioperative chemotherapy based on three months of FOLFOX4 (5-fluorouracil [5FU], folinic acid [LV], and oxaliplatin chemotherapy before surgery and three months after surgery. In the case of primary surgery, pseudo-adjuvant chemotherapy for 6 months, based on 5FU/LV, FOLFOX4, XELOX (capecitabine and oxaliplatin or FOLFIRI (5FU/LV and irinotecan, should be indicated. In potentially resectable disease, primary chemotherapy based on more intensive regimens such as FOLFIRINOX (5FU/LV, irinotecan and oxaliplatin should be considered to enhance the chance of cure. The palliative chemotherapy based on FOLFIRI, or FOLFOX4/XELOX with or without targeted therapies, is the mainstay treatment of unresectable disease. This review would provide additional insight into the problem of optimal integration of chemotherapy and surgery in the management of CRLM.

    A retrospective study was undertaken of factors affecting survival in 129 patients with cerebral metastases from malignant melanoma referred to the Department of Radiation Oncology from June '82-January '90. Their ages ranged from 19-83 years and the time interval form diagnosis of the primary tumour to development of cerebral metastases ranged from 1 month-17 years. Cerebral metastases were apparently solitary in 59 (46%) and multiple in 70 (54%) patients. Craniotomy with resection of tumour was performed in 49 patients, of whom 24 had a solitary cerebral metastasis as the only evidence of disease Most patients (94%) received radiotherapy-course. Median survival of the whole group after detection of cerebral metastases was 5 months (range <1-87+). Univariate analysis indicated that a solitary cerebral metastasis, absence of extracranial disease and tumour resection predicted improved survival, but only surgical intervention was of independent prognostic significance in a multivariate analysis. The effect of cranial irradiation on survival could not be assessed, but the dose of radiation did not influence survival. Of the 10 patients who survived for more than 2 years, 8 had total resection of a solitary cerebral metastasis. (author). 25 refs., 3 figs., 3 tabs.

    Purpose: This study evaluates the influence of several prognostic factors on overall survival and progression free survival in patients undergoing stereotactic radiosurgery (SRS) for brain metastases. Materials and Methods: Records of 61 coecutive patients with pathologically confirmed extra-cranial malignancies undergoing SRS at Yale University School of Medicine between 12/18/91 and 7/2/96 were reviewed. All patients underwent head frame localization and CT and/or MRI based treatment planning. Outcome was analyzed with respect to age, number of lesions, size of lesions, location of lesions, site and stage of primary tumor, status of primary tumor at time of SRS, history of whole brain radiation therapy (WBRT), surgery, and/or chemotherapy prior to or after SRS, delay in SRS from diagnosis of brain metastases, dose of radiation delivered, and brain metastasis free interval. Both overall survival and progression free survival were analyzed by the Kaplan-Meier method. Tests for statistical significance were performed using the Cox proportional hazards model. Results: Median follow-up was 29 months. 3% ((8(61))) of patients displayed evidence of progressive disease at the site of SRS, and 87% ((53(61))) of patients have died. Overall and progression free survival rates for the entire cohort of patients were 43.8% and 89.5% at 1 year and 11.1% and 71.4% at 2 years, respectively. Patients undergoing SRS for a solitary brain metastasis had a significant improvement in overall survival with 1 year survival rates of 52.6% vs. 32.7% for patients undergoing SRS for more than 1 brain metastasis (p=0.002). Patients who presented with progressive systemic disease at the time of SRS had an inferior overall survival with a 1 year survival rate of 15.4% compared to patients with presumed/known stable disease who had a 1 year survival rate of 51.5%/54.2% (p<0.001). Patients treated for cerebral metastases had a higher progression free survival compared to patients undergoing SRS

    Fourteen F-18 fluorodeoxyglucose (FDG) studies were carried out in 13 patients known to have bony metastases from carcinoma of the prostate. One patient was newly diagnosed. The remaining patients had various types of therapy and were considered hormonally resistant. The average age was 67. All patients had extensive bony metastases shown on the conventional Tc99m-MDP bone scans. Only about 18% of bony lesions apparent on the conventional bone scans showed corresponding increase of FDG uptake. Anatomical correlation was performed by using co-registered images of SPECT and PET in the same area. The positive FDG uptake was not related to the duration of illness, level of PSA, previous therapy, and magnitude of disease involvement. It appears that only a small percentage of bony metastases is associated with increased glycolysis. It is possible that other metabolic processes are more important than glycolysis for providing prostate cancer with a source of energy and nutrients

    Objective: To evaluate the efficacy and safety of the interventional radiological techniques for management of symptomatic portal vein (PV) occlusion. Methods: Nine patients with PV trunk occlusion were treated using interventional procedures. Four patients presented with abdominal pain, distention, and malabsorption; five presented with portal hypertension and repeated bleeding from esophagogastric varices. The etiologic factors were identified in all 9 patients, including post-transplantation of the liver in 2, hepatocellular carcinoma (HCC) associated with PV tumor thrombus in 3, post abdominal operative state in 1, and PV thrombosis in 3 cases. The portal access was established via a percutaneous transhepatic route in 4, and via a transjugular intrahepatic portosystemic shunt ( TIPS) approach in 5 patients. The interventional procedures included stent placement in 4, balloon angioplasty in 6, and catheter directed pharmacologic and mechanical thrombolysis in 7 patients. Results: The technical success was achieved in all cases. No complications related to the procedure occurred. Portal flow was reestablished in all patients after the procedures. Clinical improvement was seen in 3 patients with symptomatic PV thrombosis, characterized by progressive reduction of abdominal pain, distention, and diarrhea. Follow-up time ranged from 4 to 36 months. One patient with HCC died of multiple organs metastases at 11 months after the treatment . One patient died of intraabdominal sepsis and multiple organs failure 12 days after the procedure even though the antegrade flow was re-established in the main trunk of the PV. Patency of the PV trunk was confirmed by follow-up color Doppler ultrasound scan in the rest 7 patients, without recurrence of variceal bleeding or PV thrombus. Conclusions: Interventional minimally invasive procedures, including balloon angioplasty, stent placement, catheter directed local pharmacologic and mechanical thrombolysis, are safe and effective in

    Full Text Available Multiple sclerosis (MS is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment.

    A 65-year-old woman underwent surgery for right breast cancer (TIN1aM0) in December 2005. In March 2011, the breast cancer recurred with multiple lung and lymph node metastases. In February 2013, because of multiple brain metastases whole-brain radiation therapy was performed. In January 2014, she developed paralysis of the left leg. Spinal cord magnetic resonance imaging revealed a mass lesion (Th12 to L1 level) in the spinal cord, and she was diagnosed with intramedullary spinal cord metastasis (ISCM) from the breast cancer. Spinal cord irradiation reduced the metastasis and improved her paralysis. Although pharmacotherapy was continued, her metastases, with the exception of ISCM, progressed and she died of the disease in November 2014. It is necessary to diagnose ISCM at the time of its onset. Additionally immediate therapeutic intervention can significantly reduce the volume of ISCM, resulting in symptomatic relief from neurological deficit; in this case, radiation therapy was effective.
