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

    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. PMID:26343511

We evaluated the use of citrate-theophylline-adenosine-dipyridamole (CTAD tubes to reduce preanalytical variation in TGFβ measurements caused by ex vivo platelet activation. CTAD substantially reduced ex vivo platelet activation relative to traditional plasma collections in normal donors, which correlated with a decrease in measured TGFβ levels. We show that TGFβ levels are elevated in the majority of cancer patients with skeletal metastases, and that within-patient variability of these levels is relatively low over several weeks. Patients with elevated TGFβ could be subdivided into groups with or without evidence of platelet contribution to measured TGFβ levels. The use of CTAD tubes allows a better determination of a patient’s TGFβ status, and may improve classification of patients with oncologic disease.Keywords: TGFβ, cancer, biomarker, CTAD

    Most women with advanced breast cancer will develop bone metastases, which are associated with the development of skeletal-related events (sres) such as pathologic fractures and spinal cord compression. This article reviews the evolving definition and incidence of sres, the pathophysiology of bone metastases, and the key evidence for the safety and efficacy of the currently available systemic treatment options for preventing and delaying sres in the setting of breast cancer with bone metastases.

  5. Betulinic acid, a bioactive pentacyclic triterpenoid, inhibits skeletal-related events induced by breast cancer bone metastases and treatment

    International Nuclear Information System (INIS)

    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

    One hundred and eighteen patients with painful skeletal metastases of malignant diseases (predominantly prostate, breast and lung cancer) were treated with 150 MBq of strontium-89 chloride (Metastron, Amersham, UK) intravenously. The results were evaluated according to a score considering pain relief, mobility, analgesic intake and general feeling. In only five patients (4.2%) was no improvement observed; mild improvement was noted in 48 (40.7%), and substantial or complete improvement in 56 (47.5%) and 9 (7.6%), respectively. The mean painless period after a single {sup 89}SrCl dose was 3.3{+-}2.28 months (in patients with prostate, lung, breast and other types of cancer it was 3.65{+-}2.11, 3.29{+-}1.27, 3.08{+-}0.48 and 3.44{+-}1.36 months, respectively). During a 3-year study, {sup 89}SrCl treatment was successively repeated up to 5 times in some patients (total number of Metastron applications was 256) who benefited from the first Metastron administration and did not show signs of myelosuppression. Even after repeated treatment, relief was consistent and the duration of the period without pain increased (in particular in patients with breast cancer, in whom the period of relief was prolonged from 3.08{+-}0.48 months after the first dose to 5.33{+-}2.36 months after the fifth {sup 89}SrCl administration). The increased painless period was not observed after repeated treatment in the patient group comprising miscellaneous types of cancer, and the degree of improvement was less apparent. During the course of successive {sup 89}SrCl treatments, transient signs of myelosuppression indicated by a decrease in white cell and thrombocyte counts of at least 25% were observed 10 times after Metastron administration (twice in two patients), i.e. in 3.9% of all {sup 89}SrCl administrations; these transient haematological changes of moderate grade were closely connected with Metastron administration.

  8. Analgesic therapy of skeletal metastases with radionuclides

    International Nuclear Information System (INIS)

    The radionculide therapy of bone metastases is an unspecific palliative treatment of metastatic skeletal pain especially useful in patients suffering in multiple sites. In these cases the long-term administration of increasing doses of analgesics such as opiate which have important side effects can be reduced. The aim of this therapy is pain relief and improvement of quality of life in patients with advanced cancer. This report is focusing on options, indications and contraindications of the radionuclide therapy of metastases and on used radionuclides such as Strontium-89, Yttrium-90, Rhenium-186 (188) and Samarium-153. In oncology, the analgesic therapy using boneseeking radiopharmaceuticals in combination to drug administration should gain more importance because this therapy can be administered on an outpatient basis.

    Rhenium-188-HEDP ((188)Re-HEDP) is a new and attractive radiopharmaceutical for the treatment of metastatic bone pain. As a product of (188)W/(188)Re generator, it is convenient for clinical therapeutic use with a short physical half-life of 16.9 h and a maximal beta-energy of 2.1 MeV. We investigated the effect of (188)Re-HEDP on pain relief, analgesic intake and impairment of bone marrow function in 27 patients with bone metastases induced from prostate cancer. All patients were interviewed using a standardised set of questions before, and after therapy for 12 weeks. The patients were treated with 2700-3459 MBq of (188)Re-HEDP. Blood samples were taken weekly for 12 weeks, and a blood count was performed. Patients described an improvement on the Karnofsky performance scale from 74+/-7 to 85+/-9% 12 weeks after therapy (P=0.001). The pain score showed a maximum decrease from 44+/-18 to 27+/-20% in the third to the eight week after therapy (P=0.009). Seventy-six percent of the patients described a pain relief without increase of analgesic intake. Twenty percent of the patients could discontinue their analgesics and were pain free. Mean platelet count decreased from (286+/-75)*10(3) microl(-1) to (215+/-92)*10(3) microl(-1), and mean leucocyte count from (7.7+/-1.5)*10(3) microl(-1) to (6.0+/-1.9)*10(3) microl(-1) in the second to the fourth week after therapy. The maximal differences between the values of platelets and leucocytes before and after therapy were not statistically significant (P=0.021 and 0.094). In conclusion, (188)Re-HEDP is an effective radiopharmaceutical used in the palliative treatment of metastatic bone pain in prostate cancer and shows minimal bone marrow toxicity. PMID:12915868

    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

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

    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%).

    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.) With 6 figs., 29 refs.

    Skeletal muscle metastases are very rare events in colorectal carcinoma. By contrast, dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous manifestations and a well-recognized association with several human malignancies and, among others, colorectal cancer. Here, we report the case of a 71-year-old woman with paraneoplastic dermatomyositis followed by the development of a metastatic colon cancer. Interestingly, this patient developed multiple skeletal metastases which were preceded by the worsening of systemic symptoms of dermatomyositis. This observation suggests that, while muscle tissue is usually resistant to the development of tumor metastases, the inflammatory and immune response which characterizes and boosts paraneoplastic myopathy may represent a favorable soil for tumor cell invasion and metastasization to skeletal muscles.

    International Nuclear Information System (INIS)

    Autopsy-based studies report the occurrence of skeletal metastases in up to 70% of the patients with breast or prostate cancer. Common localization of bone metastases in the axial skeleton is probably due to sluggish blood flow in the red marrow (which is particularly abundant in the axial skeleton) and to the fact that venous blood from the pelvis or breast flows through the vertebral-venous plexus (Batson circulation); both these occurrences represent predisposing conditions for tumor seeding

  20. Pathogenesis and pharmacological treatment of bone pain in skeletal metastases

    International Nuclear Information System (INIS)

    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

    We present a rare case of intrahepatic cholangiocarcinoma (ICC) with multiple skeletal muscle metastases. The patient was a 55-year-old Asian woman presenting with abdominal pain; abdominal and pelvic computed tomography and magnetic resonance cholangiopancreatography revealed an unresectable ICC with hepatic metastasis and metastastatic lymphadenopathy in the porto-caval area. After 3 mo of treatment with palliative radiotherapy and chemotherapy, magnetic resonance imaging of the thoracolumbar spine detected right psoas muscle and paraspinous muscle metastases. We performed an ultrasound-guided percutaneous fine-needle biopsy that confirmed a similar pattern of poorly differentiated adenocarcinoma. The patient treated with palliative chemotherapy and achieved 10 mo of survival. Here we report the first case quickly spread to multiple sites of muscle even though the three-month treatment, compare to the other cases reported muscle metastases at diagnosis. PMID:25684968

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

    In oncology, the skeleton is one of the most frequently encountered sites for metastatic disease and thus early detection not only has an impact on an individual patient's management but also on the overall outcome. Multiparametric and multimodal hybrid PET/computed tomography and PET/MR imaging have revolutionized imaging for bone metastases, but irrespective of tumor biology or morphology of the bone lesion it remains unclear which imaging modality is the most clinically relevant to guide individualized cancer care. In this review, we highlight the current clinical challenges of PET imaging in evaluation and quantification of skeletal tumor burden and its impact on personalized cancer management. PMID:27321034

    Central nervous system or brain metastases traditionally occur in 10-16% of metastatic breast cancer patients and are associated with a dismal prognosis. The development of brain metastases has been associated with young age, and tumors that are estrogen receptor negative, Her-2+ or of the basal phenotype. Treatment typically includes whole brain irradiation, or either stereotactic radiosurgery or surgery with whole brain radiation, resulting in an approximately 20% one year survival. The blood-brain barrier is a formidable obstacle to the delivery of chemotherapeutics to the brain. Mouse experimental metastasis model systems have been developed for brain metastasis using selected sublines of human MDA-MB-231 breast carcinoma cells. Using micron sized iron particles and MRI imaging, the fate of MDA-MB-231BR cells has been mapped: Approximately 2% of injected cells form larger macroscopic metastases, while 5% of cells remain as dormant cells in the brain. New therapies with permeability for the blood-brain barrier are needed to counteract both types of tumor cells. PMID:17473372

    Resection of colorectal liver metastases is a treatment standard because patients experience long-term disease-free survival or are even cured after undergoing this procedure. Improved surgical techniques for liver resection in combination with downsizing liver metastases by chemotherapy, interventions to induce liver hypertrophy before resection, and the use of ablative techniques have allowed us to expand the indications for liver surgery and local treatment in situations with limited metastatic colorectal cancer. Resectability and identification of patients who might benefit from liver surgery and local ablative techniques are key factors for the treatment of patients with colorectal cancer. Despite the wide acceptance of liver surgery and ablative techniques, there are many open questions on the management of limited metastatic disease, such as which patients benefit from an aggressive surgical approach, what the indications for ablative and other local techniques are, and what the role of chemotherapy is for patients with resectable or resected disease. Unfortunately, results of randomized trials are only available for a limited number of these questions. PMID:27249722

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

    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.

    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.

  13. A Systematic Overview of Radiation Therapy Effects in Skeletal Metastases

    International Nuclear Information System (INIS)

    A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for skeletal metastases is based on data from 16 randomized trials. Moreover, data from 20 prospective studies, 5 retrospective studies and 22 other articles were used. A total of 63 scientific articles are included, involving 8,051 patients. The results were compared with those of a similar overview from 1996 including 13,054 patients. The conclusions reached can be summarized as follows: Irradiation of skeletal metastases is, with few exceptions, a palliative treatment. There is strong evidence that radiotherapy of skeletal metastases gives an overall (complete and partial pain relief) in more than 80% of patients. There is strong evidence that the duration of pain relief in at least 50% of patients lasts for S6 months. There is convincing evidence that pain relief, in terms of degree and duration, does not depend on the fractionation schedules applied. Irrespective of the fractionation schedule used at irradiation, the number of later complications, such as spinal cord compression or pathological fractures, at the index fields are low. There are some data showing that the difference in cost between single and multifraction treatment is small. However, these data do not permit any firm conclusions to be drawn. Several reports indicate that early diagnosis and early therapy of spinal cord compression are the two most important predictors of a favourable clinical outcome after radiotherapy. However, no controlled studies have been undertaken. When the diagnosis of spinal cord compression is late, a favourable outcome might depend on the radio-responsiveness of the tumour. The documentation is weak and no conclusions can be drawn. There is some evidence that a small proportion

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

    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

    An analysis of X-ray findings in 146 cases of metastatic skeletal involvement in thyroid cancer (TC) led to the following conclusions: the formation of solitary foci of osteoclastic type mainly in the central parts of the skeleton (the vertebral column, ribs, pelvic bones) was typical of TC metastasizing to the bones. Metastatic growth was more often accompanied by bone distention (38.1%) than by the formation of major bone defects (18.2%), showing a tendency to rather slow growth. With tumor growth, the involvement of the adjacent bones via the ligamentous-articular apparatus and interverterbral disks was nated, metastases being localized in the vertebrae, costal articular parts, and the adjacent parts of the iliac bones and sacrum

    Full Text Available Cancer metastasis is the major cause of cancer morbidity and mortality, and accounts for about 90% of cancer deaths. Although cancer survival rate has been significantly improved over the years, the improvement is primarily due to early diagnosis and cancer growth inhibition. Limited progress has been made in the treatment of cancer metastasis due to various factors. Current treatments for cancer metastasis are mainly chemotherapy and radiotherapy, though the new generation anti-cancer drugs (predominantly neutralizing antibodies for growth factors and small molecule kinase inhibitors do have the effects on cancer metastasis in addition to their effects on cancer growth. Cancer metastasis begins with detachment of metastatic cells from the primary tumor, travel of the cells to different sites through blood/lymphatic vessels, settlement and growth of the cells at a distal site. During the process, metastatic cells go through detachment, migration, invasion and adhesion. These four essential, metastatic steps are inter-related and affected by multi-biochemical events and parameters. Additionally, it is known that tumor microenvironment (such as extracellular matrix structure, growth factors, chemokines, matrix metalloproteinases plays a significant role in cancer metastasis. The biochemical events and parameters involved in the metastatic process and tumor microenvironment have been targeted or can be potential targets for metastasis prevention and inhibition. This review provides an overview of these metastasis essential steps, related biochemical factors, and targets for intervention.

  4. Predicting the presence of extracranial metastases in patients with brain metastases upon first diagnosis of cancer

    International Nuclear Information System (INIS)

    This study aimed to determine factors allowing the prediction of extracranial metastases in patients presenting with brain metastases at the first diagnosis of cancer. Data from 659 patients with brain metastases upon first diagnosis of cancer were retrospectively analyzed. The parameters age, gender, Karnofsky performance score (KPS), primary tumor type and number of brain metastases were compared between 359 patients with extracranial metastases and 300 patients without extracranial metastases. Additional analyses were performed for patients with the most unfavorable and those with the most favorable characteristics. The comparison of patients with versus without extracranial metastases revealed significant differences between the groups in terms of KPS (p < 0.001) and number of brain metastases (p < 0.001). Of the study patients, 113 had both most unfavorable characteristics, i.e. KPS ≤ 50 and ≥ 4 brain metastases. The sensitivity for identifying patients with extracranial metastases was 82 %; specificity was 51 %. A total of 50 patients had KPS ≥ 90 and only one brain metastasis. The sensitivity for identifying patients without extracranial metastases was 86 %; specificity was 58 %. The combination of KPS and the number of brain metastases can help to predict the presence or absence of extracranial metastases. (orig.)

    Bone density is controlled by interactions between osteoclasts, which resorb bone, and osteoblasts, which deposit it. The semaphorins and their receptors, the plexins, originally shown to function in the immune system and to provide chemotactic cues for axon guidance, are now known to play a role in this process as well. Emerging data have identified Semaphorin 4D (Sema4D) as a product of osteoclasts acting through its receptor Plexin-B1 on osteoblasts to inhibit their function, tipping the balance of bone homeostasis in favor of resorption. Breast cancers and other epithelial malignancies overexpress Sema4D, so we theorized that tumor cells could be exploiting this pathway to establish lytic skeletal metastases. Here, we use measurements of osteoblast and osteoclast differentiation and function in vitro and a mouse model of skeletal metastasis to demonstrate that both soluble Sema4D and protein produced by the breast cancer cell line MDA-MB-231 inhibits differentiation of MC3T3 cells, an osteoblast cell line, and their ability to form mineralized tissues, while Sema4D-mediated induction of IL-8 and LIX/CXCL5, the murine homologue of IL-8, increases osteoclast numbers and activity. We also observe a decrease in the number of bone metastases in mice injected with MDA-MB-231 cells when Sema4D is silenced by RNA interference. These results are significant because treatments directed at suppression of skeletal metastases in bone-homing malignancies usually work by arresting bone remodeling, potentially leading to skeletal fragility, a significant problem in patient management. Targeting Sema4D in these cancers would not affect bone remodeling and therefore could elicit an improved therapeutic result without the debilitating side effects. PMID:26910109

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

    The radionculide therapy of bone metastases is an unspecific palliative treatment of metastatic skeletal pain especially useful in patients suffering in multiple sites. In these cases the long-term administration of increasing doses of analgesics such as opiate which have important side effects can be reduced. The aim of this therapy is pain relief and improvement of quality of life in patients with advanced cancer. This report is focusing on options, indications and contraindications of the radionuclide therapy of metastases and on used radionuclides such as Strontium-89, Yttrium-90, Rhenium-186 (188) and Samarium-153. In oncology, the analgesic therapy using boneseeking radiopharmaceuticals in combination to drug adminstration shoud gain more importance because this therapy can be administered on an outpatient basis. (orig.) [German] Die nuklearmedizinische Strahlentherapie von Skelettmetastasen ist eine unspezifische, symptomatisch-palliative Schmerztherapie von ossaeren Metastasen. Sie ist insbesondere bei multiplen Lokalisationen eine erfolgreiche und kostenguenstige Therapieoption, die zu einer Einsparung von Analgetika, v.a. von stark nebenwirkungsbehafteten Opiaten, fuehren kann. Die palliative Schmerztherapie hat das primaere Ziel, bei einem in der Regel fortgeschrittenen Tumorleiden durch die Schmerzlinderung die Lebensqualitaet des Patienten deutlich zu verbessern. In der vorliegenden Arbeit werden die Moeglichkeiten, Indikationen und Kontraindikationen der Radionuklidtherapie vorgestellt und die einzelnen Radiopharmaka, die zur Anwendung kommen koennen (Sr-89, Y-90, Re-186[188], Sm-153), einander gegenuebergestellt. Die nuklearmedizinische Schmerztherapie, die haeufig noch zu weit im Hintergrund steht, sollte als Ergaenzung zur medikamentoesen Therapie weiter in den Blickpunkt der Onkologie gerueckt werden, da sie ohne stationaeren Aufenthalt auch von erfahrenen niedergelassenen Nuklearmedizinern durchgefuehrt werden kann.

  12. Treatment strategies for lung cancer brain metastases

    International Nuclear Information System (INIS)

    Forty-one patients suffered initial relapses with brain metastasis after surgery for non-small lung cancer at our hospital between 1978 and 1995. These patients were a total of 8.4% of all cases of surgical removal, and had an average relapse period of 8.6 months ± 8.0 months after surgery on the primary lesions. Of these, surgical removal of metastasized lesions was performed on 18 patients (43%), in which the 5-year post-operative survival rate was 35.7%, and the median survival time was good at 28 months. It was found that the survival period was significantly extended in the group whose relapse period was less than one year after surgery on the primary lesions, and in the group who received cranial irradiation post-operatively on the metastasized brain lesion. Following surgery on the metastasized lesion, second relapses occurred in nine patients, and six patients suffered from second relapses in the brain, of which four did not receive cranial irradiation post-operatively. Cases of radiotherapy in patients of 70 years of age or more frequently manifested post-radiotherapy subacute neuropathy. From the above, it is thought that the following procedures should be adopted: Periodic examination for brain metastasis during the 24 months following surgery for non-small cell lung carcinoma for purposes of early detection; in cases where brain metastasis is detected, if no metastasis is identified in other organs, a policy of surgical removal should be adopted where possible; and, in cases of 70 years of age or less following surgery on the metastasized lesion, cranial irradiation should be considered.

    Bone scans were obtained in 100 patients with carcinoma of the cervix in order to search for occult skeletal metastases. Scans revealed metastases in 4 patients with advanced stages of disease, but the scans in 79 patients with Stage 0, I, or II disease were negative. The scans in 14 patients showed renal asymmetry; 11 of these had obstructive uropathy due to tumor invasion or radiation therapy. Bone scanning does not seem warranted as a screening test in asymptomatic patients with Stage 0, I, or II carcinoma. If the test is done, renal symmetry should be carefully evaluated.

  17. Preliminary clinical study of 89Sr in palliation in painful skeletal metastases

    International Nuclear Information System (INIS)

    89Sr has shown to produce significant pain relief in patients with skeletal metastases from advanced cancer. According to the requirements from the drug agency of Chinese ministry of health, we had treated 27 patients with painful bone metastases to testify the safety and efficiency of Metastron (89Sr injection solution imported from the Amersham company, UK). Strontium was used for the treatment of painful bone metastasis in 27 patients. 2 cases was excluded by missed follow-up, the other 25 cases with metastatic prostate carcinoma, lung cancer, breast cancer have been evaluated in a standard quantitative pain measures before the treatment. Pain scores of these patients were between 6 ∼ 16. According to the guideline of this pharmaceutical, Metastron was given intravenously to these patients as a 1.48 MBq/kg dose. All the patients were monitored at least 3 months. Pain score, radiotoxocity and immediately reaction were observed in the follow-up. Clinically significant metastatic pain relief can be observed in most patients. Total efficiency is 77.8% respectively, patients' life quality have been improved. No clinically significant adverse effects or myelosuppression were observed in most patients. The mild decrease of white blood cell can be seen in 32% patients and platelet counts in 60% patients. Most of these patients can recover except 1 case. For the case, further clinical data show a little change in liver function. Absolute granulocyte counts did not fall bellow 2000 in any patients. Significant increased pain (flare) occurred in 55.5% patients after the injection of Metastron. The flare had been lasting 3-7 days. Only one patient's pain last more than 20 days. It is concluded that 89Sr is an effective agent in palliative therapy for metastatic bone pain in-patients with prostate or breast carcinoma. More than 3 months pain relief can be observed in 94.4% patients. There is only one patient lasted for 2 months. 7 cases had repeated the bone scan before

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

    2016-01-01

    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.

    This study aimed to determine factors allowing the prediction of extracranial metastases in patients presenting with brain metastases at the first diagnosis of cancer. Data from 659 patients with brain metastases upon first diagnosis of cancer were retrospectively analyzed. The parameters age, gender, Karnofsky performance score (KPS), primary tumor type and number of brain metastases were compared between 359 patients with extracranial metastases and 300 patients without extracranial metastases. Additional analyses were performed for patients with the most unfavorable and those with the most favorable characteristics. The comparison of patients with versus without extracranial metastases revealed significant differences between the groups in terms of KPS (p < 0.001) and number of brain metastases (p < 0.001). Of the study patients, 113 had both most unfavorable characteristics, i.e. KPS ≤ 50 and ≥ 4 brain metastases. The sensitivity for identifying patients with extracranial metastases was 82 %; specificity was 51 %. A total of 50 patients had KPS ≥ 90 and only one brain metastasis. The sensitivity for identifying patients without extracranial metastases was 86 %; specificity was 58 %. The combination of KPS and the number of brain metastases can help to predict the presence or absence of extracranial metastases. (orig.)

    2016-01-01

    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical significance of IPN and SPCM detected at the primary staging in CRC. Study I was a systematic review of published studies on IPN in CRC focusing on the prevalence and radiological characteristics of IPN proving to be malignant. This knowledge would be of value in management strategies for IPN. On average 9% of all patients staged with a thoracic CT had IPN, however, the prevalence varied significantly between patients series. This was mainly attributed to varying/lacking definitions on IPN and variable radiological expertise in the assessment of the scans. Data were too inconsistently reported in the case series for a robust statement to be made on potential radiological characteristics suggestive of malignancy in IPN. Lymph node metastasis was the most common clinicopathological finding associated with malignancy of IPN. In conclusion, one patient of every 100 scanned patients had an IPN proving to a SPCM at follow-up, but we found no evidence that IPN should result in intensified diagnostic work-up besides routine follow-up for CRC. Study II was an analysis of the

  6. Treatment of Bone Metastases with Radium-223 in Patients with Castration Resistant Prostate Cancer (CRPC): Alternative or Complementary to Innovative Molecular Therapies?

    International Nuclear Information System (INIS)

    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

  13. Palliative radiotherapy for cancers other than brain or bone metastases

    International Nuclear Information System (INIS)

    Radiotherapy plays a major role in the palliation of patients with uncontrolled cancer and is important in any comprehensive care program. There are fewer phase III trials on palliative radiotherapy of other symptomatic tumors than there are for the treatment of bone metastases. However, the number of such trials has been increasing, especially for the treatment of lung cancer. In particular, symptoms from bronchial obstruction, superior vena cava obstruction and other solid tumors as well as cancer-related bone pain and brain metastases can all be palliated effectively with radiotherapy.

  14. Brain metastases from esophageal cancers. Clinical features and treatment results

    International Nuclear Information System (INIS)

    Metastatic brain tumors from esophageal cancer are relatively rare. We analyzed the clinical features and results of treatment in 14 cases of brain metastases from esophageal carcinoma. The average time to diagnosis of brain metastases in the 11 patients with metachronous lesions was 13 months. The average age of patients at the diagnosis of brain metastasis was 65 years. Most patients had T4 or N1 disease at the time of diagnosis of esophageal cancer. Performance status of grade 3 was most frequent at the time of diagnosis of brain metastasis. Treatment for brain metastases was surgery followed by radiation in five cases, radiotherapy alone in seven cases, and conservative treatment in two cases. The median survival time of all patients from the treatment of brain metastases was 2 months, with only one patient alive after more than one year. Improvement in neurological symptoms was demonstrated in 42% of cases. These extremely poor treatment results reflect the fact that most patients at the time of diagnosis of brain metastasis had poor performance status and the presence of extracerebral metastases. Therefore, a short-course, high-dose-per-fraction treatment for brain metastases from esophageal cancer should be selected from the viewpoint of quality of life. (author)

    International Nuclear Information System (INIS)

    Objective: To evaluate the MRI diagnosis of brain metastases of lung cancer. Methods: MR findings of 45 patients with brain metastases of lung cancer confirmed by pathological examinations were studied retrospectively. Both non-contrast and contrast-enhanced scans were performed in all cases, in which 0.2 mmol/kg of Gd-DTPA was administrated in 40 patients and 0.1 mmol/kg in 5 patients. Results: The brain metastases of lung cancer were solitary or multiple, and round or oval in shape. Peri-lesion brain edema may present or absent. The location of metastases were mainly in supratentorial areas between the cortex and white matter but also were frequently seen in cerebella. Contrast-enhanced imaging revealed not only the lesions silent in non-enhanced scan, but also shown more nodules in 85% of patients. Conclusion: MRI, especially with contrast-enhanced imaging was a very good diagnostic modality for detecting brain metastases of lung cancer

    Full Text Available Mucoepidermoid carcinomas (MECs of lung are rare neoplasms originating in bronchial submucosal glands and comprising 0.1-0.2% of primary lung cancers. MECs, the most common malignancy in salivary glands, were earlier thought to occur only in salivary glands. Later studies showed that they can arise as a primary in bronchus, esophagus, lacrimal glands, pancreas, thymus and thyroid gland. Initially described as a benign adenoma, it is now considered to be a malignant epithelial tumor. There have been reports of metastases to regional lymph nodes, other parts of the lung and distant organs. Cavitary lesion in MEC of lung is rare. Here, we report a case of MEC of lung with metastases to skeletal muscles of thigh and arm. To the best of our knowledge, this is the only case of MEC of lung presenting with such unusual pattern of metastasis as presenting feature with almost no symptoms of primary lesion.

  18. Combination radiation therapy for bone metastases in thyroid cancer

    International Nuclear Information System (INIS)

    Full text: Distant metastases of thyroid carcinoma (TC) occur due to dissemination of cancer cells through the lymph and blood vessels. They develop in 10-15% of patients with differentiated thyroid carcinoma and are the main cause of death in cancer patients. Appearance of distant metastases depends on a number of factors, i.e. the age of the patients (chiefly in children and those over 45); small size tumors; invasive growth of the tumor outside the thyroid capsule; involvement of the sentinel lymph nodes; poor differentiation of the tumor; incomplete surgical removal of the tumor. Distant metastases mainly localize in the lungs and/or bones. In thyroid cancer patients with suspected bone metastases the latter are revealed radiologically on the primary examination (approximately in 95.9% of cases). In 25% of them, they are seen at body scan with I-131 on residual activities. Probability of visualization of iodine-positive bone metastases is higher at ablation of residual thyroid tissue. When the metastases are revealed by x-ray study, they cannot be treated using I-131, which emphasizes the necessity of other methods of treatment: surgery and distant radiation therapy. But due to multiple character of bone metastases surgery for these metastases is impossible. Within the period of 1999-2004 we studied 310 patients with differentiated TC aged 22-72 (of them 254 women and 56 men). Bone metastases were revealed in 15 (4.8%) patients, of them 13 women and 2 men aged 46-68. As to the stage of the tumor with bone metastases, the patients were grouped as follows: T1 N0 M0 -1 (6.7%), T2-3 N0 M0 -1 (6.7%), TxNxMo-4 (26.7%), T1-4 N0 -1M1-9 (60%) patients. Of the 15 patients with bone metastases, papillary cancer was verified in 5 (33.3%) patients, follicular in 5 (33.3%) papillary cancer follicular variant in 1 (6.7%), medullary in 4 (26.3%).

Diaphyses of long tubular bones, as well as plane bone and spine are the most typical localization of bone metastases. Their localization in feet and wrists was noted in some cases. Bone metastases are diagnoses by X-ray diffraction analysis and radioisotope examination of skeletone. Osteolific type of pathological process is the characteristic radiological sign of metastases of hypernephrosis cancer in bone system

  2. Kidney metastases of the lung cancer

    International Nuclear Information System (INIS)

    Renal metastases of the lung tumours are most frequently clinically silent, and their diagnosis is confirmed by postmortem examination. This study presents a patient with diagnosed metastasis of squamous cell lung carcinoma to the kidney. Fifteen months after a tumour of the left lung was removed, ultrasonography and computer tomography revealed the presence of a tumour of the left kidney. Left-sided nephrectomy was performed and histopathological examination confirmed the presence of metastatic squamous cell carcinoma. (authors)

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

    Lutsenko, I.V. (Nauchno-Issledovatel' skij Onkologicheskij Inst., Moscow (USSR))

    Metastases of thyroid cancer to the chest cavity organs were detected in 19.4%. They were found most frequently in the pulmonary tissue (75.8%), in the mediastinal lymph nodes (57.9%), less frequently in the lymph nodes of the roots of the lungs (30.4%) and very rarely in the pleura (2.6%). X-ray signs of metastases are identical for all histological structures of thyroid cancer. The most typical are multiple lesions (91.8%). The nodular form is found in 74.5%, the nodal form in 17.2.%. Solitary metastases and cancerous lymphangitis are rarely noted (7.2 and 0.9% respectively. The regression of metastases, spontaneous pneumothorax and pneumonia are rarely observed as well (1.8, 0.9 and 1.8%) respectively). The doubling time of the size of metastatic tumors of thyroid cancer ranges from 52 to 379 days. The use of radioactive iodine and hormones inhibits their growth rates.

  8. PET/CT in lung cancer with brain metastases

    International Nuclear Information System (INIS)

    PET/CT is a method for diagnosis, staging and evaluating the effect of lung cancer treatment. The lung cancer is one of the cancers with most frequent localization of the metastases in brain. We have studied with 18 FDG-PET/CT 45 patients, 26 male (57.8%) and 19 female (42.2%) between 41 to 71 years of age, diagnosed with non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) and brain metastases by 63 examinations. Examinations have been executed on integrated apparatus Phillips Gemini TF (2009). 18FDG has been applied by i.v. injection with activity 0.14 mCi/kg. Patients are staged by TNM classification. Survival has been evaluated by Kaplan-Meier method, for comparison of studied groups the log rank (Mantel-Cox) has been applied. (P<0.05). Multiple metastases in brain have been detected in 8 patients (17%). Hypo-metabolic have been found in 7 patients (14.9%), with hyper-metabolic - 10 (21.3%), with ring-like -7 (14.9%). In patients with metastases operated on, in the area of the operative intervention a hypo-metabolic zone has been found. New metastases have been found in 3 patients after operation. The median of survival of the patients with NSCLC in months for stage II and III has been estimated to 25.2 months and for stage IV to 12.9 months and total survival to 16.8 months (P=0.03). The median of survival in months for patients with NSCLC and SCLC in II and III stage is estimated to 28.4 months, for stage IV is estimated to 12.4 months and total survival is estimated to 16.8 months (P=0.04). Survival of the patients with NSCLC and SCLC with brain metastases is significantly dependent on the clinical stage. The median of survival in patients to III stage is double times longer than the median of survival of patients in IV stage. The median of total survival is estimated to 16.8 months. Most common histological form of the lung cancer in case of metastases in brain is adenocarcinoma. The established by PET/CT lesions in asymptomatic patients

    Bone metastasis is a common and debilitating consequence of lung cancer: 30%-40% of patients with non-small cell lung cancer develop bone metastases during the course of their disease. Lung cancer cells find a favorable soil in the bone microenvironment due to factors released by the bone matrix, the immune system cells, and the same cancer cells. Many aspects of the cross-talk among lung tumor cells, the immune system, and bone cells are not clear, but this review aims to summarize the recen...

  11. Radiotherapy for brain metastases of the breast cancer

    International Nuclear Information System (INIS)

    Twenty-two patients with brain metastases of breast cancer treated by irradiation between 1974 and 1983 were reviewed. Significant neurologic improvement was obtained in 80 %. The median duration of symptomatic palliation caused by irradiation and the median survival from the diagnosis of brain metastases were 3.0 months and 5.0 months, respectively. As a favorable prognosis can be expected for patients showing good performance, minor neurologic disorders, a long latent period between the first treatment of the primary lesion and the onset of the brain metastasis, and without extracranial metastases, irradiation with more than 40 Gy is recommended. Sequential CT examinations were useful to judge the effectiveness of treatment. (author)

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

    2009-04-01

    Full Text Available Abstract Background Prognostic scores might be useful tools both in clinical practice and clinical trials, where they can be used as stratification parameter. The available scores for patients with brain metastases have never been tested specifically in patients with primary breast cancer. It is therefore unknown which score is most appropriate for these patients. Methods Five previously published prognostic scores were evaluated in a group of 83 patients with brain metastases from breast cancer. All patients had been treated with whole-brain radiotherapy with or without radiosurgery or surgical resection. In addition, it was tested whether the parameters that form the basis of these scores actually have a prognostic impact in this biologically distinct group of brain metastases patients. Results The scores that performed best were the recursive partitioning analysis (RPA classes and the score index for radiosurgery (SIR. However, disagreement between the parameters that form the basis of these scores and those that determine survival in the present group of patients and many reported data from the literature on brain metastases from breast cancer was found. With the four statistically significant prognostic factors identified here, a 3-tiered score can be created that performs slightly better than RPA and SIR. In addition, a 4-tiered score is also possible, which performs better than the three previous 4-tiered scores, incl. graded prognostic assessment (GPA score and basic score for brain metastases (BSBM. Conclusion A variety of prognostic models describe the survival of patients with brain metastases from breast cancer to a more or less satisfactory degree. However, the standard brain metastases scores might not fully appreciate the unique biology and time course of this disease, e.g., compared to lung cancer. It appears possible that inclusion of emerging prognostic factors will improve the results and allow for development and validation

    Breast cancer is the most prevalent cancer among females worldwide. It has long been known that cancers preferentially metastasize to particular organs, and bone metastases occur in ∼70% of patients with advanced breast cancer. Breast cancer bone metastases are predominantly osteolytic and accompanied by bone destruction, bone fractures, pain, and hypercalcemia, causing severe morbidity and hospitalization. In the bone matrix, transforming growth factor-β (TGF-β) is one of the most abundant g...

    Lymph node status is a key prognostic factor in penile squamous cell carcinoma.Recently,growing evidence indicates a multimodality approach consisting of neoadjuvant chemotherapy followed by consolidation surgery improves the outcome of locally advanced penile cancer.Thus,accurate estimation of survival probability in node-positive penile cancer is critical for treatment decision making,counseling of patients and follow-up scheduling.This article reviewed evolving developments in assessing the risk for cancer progression based on lymph node related variables,such as the number of metastatic lymph nodes,bilateral lymph node metastases,the ratio of positive lymph nodes,extracapsular extension of metastatic lymph nodes,pelvic lymph node metastases,metastatic deposit in sentinel lymph nodes and N stage in TNM classification.Controversial issues surrounding the prognostic value of these nodal related predictors were also discussed.

  18. CT images in brain metastases of the primary lung cancer

    International Nuclear Information System (INIS)

    Computed tomography (CT) of the brain was carried out in 366 patients with lung cancer in order to evaluate brain metastases. Suggestive evidences of metastases such as low density or contrast enhancement were observed in 65 cases (18%), although 26% of the metastatic cases revealed no signs or symptoms of neurological disorders. These facts emphasize that brain CT should be conducted in all patients with lung cancer, irrespective of signs and symptoms. A solitary lesion was noted in 37 out of 65 metastatic cases. More than 80% of the metastatic lesions were demonstrated as iso-density on plain CT films and were enhanced by intravenous injection of contrast medium. Although CT images of metastatic lesions reveal certain characteristic appearances according to the histologic type of the primary cancer, perifocal low density and central cavitation were observed independent of histologic type.

    Orbital metastases from breast cancer (BC) are rare, but often debilitating. BC accounts for nearly half of metastases to the orbit. Orbital metastases may be discovered years after the initial diagnosis of BC, and are rare at initial presentation. A search of the institutional data base at an academic cancer center identified BC patients who developed or presented with orbital metastases from 2000 to 2013. Baseline characteristics, treatment modalities, survival and treatment responses were collected from the electronic medical record. There were 20 patients identified with orbital metastases (0.7% of all BC cases). The median age at diagnosis of BC was 49 years; 80% had estrogen positive disease. The interval between the initial diagnosis of BC and the presentation of orbital metastases was 8.5 years (0-19 years). Orbital disease was the initial presentation of BC in two cases. Three patients developed bilateral orbital metastases and seven had accompanying brain metastases. The most common presentation was decreased vision (55%), followed by diplopia (25%). The median survival after orbital metastases was 24 months. Thirteen patients (65%) received local radiation therapy. Of those radiated, 90% reported improvement of orbital symptoms. Other treatments included intraocular bevacizumab, surgery, and systemic therapy. Orbital metastases tend to occur in estrogen receptor positive disease and are often found years after BC onset. Orbital metastases may be associated with the development of brain metastases. Radiotherapy is the preferred local therapy and had high symptom control in this cohort. Oncologists should be aware of the signs of orbital metastases and the treatment options. PMID:27143519

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

    2014-01-01

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

    Full Text Available Abstract Background Skeletal metastases are often accompanied by bone pain. To investigate the clinical meaning of bone pain associated with skeletal metastasis in breast cancer patients after surgery, we explored whether the presence of bone pain was due to skeletal-related events (SREs or survival (cause specific death, CSD, retrospectively. Methods Consecutive breast cancer patients undergoing surgery between 1988 and 1998 were examined for signs of skeletal metastasis until December 2006. Patients who were diagnosed as having skeletal metastasis were the subjects of this study. Bone scans were performed annually for 5, 7 or 10 years; they were also conducted if skeletal metastasis was suspected. Data concerning bone pain and tumor markers at the time of skeletal metastasis diagnosis, and data relating to various factors including tumors, lymph nodes and hormone receptors at the time of surgery, were investigated. The relationships between factors such as bone pain, SRE and CSD were analyzed using the Kaplan-Meier method and Cox's analysis. Results Skeletal metastasis occurred in 668 patients but the pain status of two patients was unknown, therefore 666 patients were included in the study. At the time of skeletal metastasis diagnosis 270 patients complained of pain; however, 396 patients did not. Analysis of data using Cox's and Kaplan-Meier methods demonstrated that patients without pain had fewer SREs and better survival rates than those with pain. Hazard ratios regarding SRE (base = patients without pain were 2.331 in univariate analysis and 2.243 in multivariate analysis. Hazard ratios regarding CSD (base = patients without pain were 1.441 in univariate analysis and 1.535 in multivariate analysis. Similar results were obtained when analyses were carried out using the date of surgery as the starting point. Conclusion Bone pain at diagnosis of skeletal metastasis was an indicator of increased SRE and CSD. However, these data did not

    Clinical management of breast cancer is increasingly personalized and based on molecular profiling. Often, primary tumors are used as proxies for systemic disease at the time of recurrence. However, recent studies have revealed substantial discordances between primary tumors and metastases, both with respect to traditional clinical treatment targets and on the genomic and transcriptomic level. With the increasing use of molecularly targeted therapy, discordance of actionable molecular targets between primary tumors and recurrences can result in nonoptimal treatment or unnecessary side effects. The purpose of this review is to illuminate the extent of cancer genome evolution through disease progression and the degree of molecular concordance between primary breast cancers and matched metastases. We present an overview of the most prominent studies investigating the expression of endocrine receptors, transcriptomics, and genome aberrations in primary tumors and metastases. In conclusion, biopsy of metastatic lesions at recurrence of breast cancer is encouraged to provide optimal treatment of the disease. Furthermore, molecular profiling of metastatic tissue provides invaluable mechanistic insight into the biology underlying metastatic progression and has the potential to identify novel, potentially druggable, drivers of progression.

    2009-12-01

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

    2016-06-01

    Occurring either synchronously or metachronously to the primary tumor, peritoneal metastases (PM) are diagnosed in 8 to 20 % of the patients with colorectal cancer (CRC). Prognosis of these patients appears to be worse than those with other sites of metastases. While systemic therapy has shown significant prolongation of survival in patients with stage IV colorectal cancer, the outcomes in the subset of patients with PM has been much inferior. Over the last 2 decades, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) have been effective in substantially prolonging survival in patients with colorectal PM and have the potential to cure certain patients as well. This article reviews the current evidence for CRS and HIPEC to treat colorectal PM as well as future research going on in this form of locoregional treatment. PMID:27065708

    Full Text Available Lung cancer is mostly common occurring oncological disease in the developed countries. Currently lung cancers are subdivided into nonsmall-cell (adenocarcinoma, large-cell, squamous cell and small-cell. The difference in the clinical and morphological picture leads to the necessity of choosing therapeutic approaches to patients of various groups.Lung cancer should be referred to encephalotropic diseases since metastatic lesion of the central nervous system is sufficiently common complication. Successes of complex treatment of primary tumor result in increase of total longlivety currently ther is ageing of patients suffering lung cancer. These factors increase the risk of metastatic lesions of the brain.Interest to the problem of neurosurgical treatment of patients suffering lung cancer is determined by frequency of lesion, varicosity of morphological variants of the disease, requiring various algorithms of treatment and diagnosis.The main role of neurosurgical intervention in cerebral metastases of lung cancer consist in creation of the paled of carrying out combined therapy. Ideally, a neurosurgical operation should be carried out with clearcut observance of oncological principles of ablasty.Adequate comprehensive approach to treatment or patients with cerebral metastases of various forms of lung cancer with the developed of optimal tactics of and stages of treatment would make it possible to increase duration and quality of life of patients.

  9. Treatment of brain metastases from primary lung cancer

    International Nuclear Information System (INIS)

    Purpose: A retrospective study of patients treated at the Peter MacCallum Cancer Institute for brain metastases from primary carcinoma of the lung is presented. Methods and Materials: The medical records of 416 patients with the diagnosis of primary carcinoma of the lung who presented with, or subsequently developed, brain metastases during the period January 1984 to December 1987 were reviewed. Information on a number of factors of potential prognostic significance (sex, age, histology, performance status and interval between diagnosis of the primary and brain metastases) was collected. Details of surgery, radiation and steroid usage were recorded, and any steroid side effects documented. Survival was calculated from the date of diagnosis of brain metastases. Stepwise regression based on Cox's proportional hazards model was used to determine significant prognostic factors affecting survival. Patients with and without steroid side effects were compared using Yate's corrected chi-square test. Results: The overall estimated median survival was only 3.3 months (95% confidence interval 2.9-3.7 months). Only two factors were found to be associated with a significantly improved survival--surgical intervention and good performance status. After taking these two factors into account, the dose of radiation used (< 30 Gy or ≥ 30 Gy) did not influence survival. There was a 3% incidence of gastric bleeding or perforation in patients taking steroids, with a 40% fatality rate. Predisposing factors to gastric side effects were a prior history of peptic ulcer and/or aspirin or nonsteroidal anti-inflammatory drug consumption. Conclusion: Radiation of brain metastases from primary lung cancer results in modest survival benefit. Radiation dose (< 30 Gy or ≥ 30 Gy) is not a significant determinant of survival. Other treatment modifications, such as concurrent radiation and chemotherapy, should be explored. Steroids should be used with caution as fatal side effects can occur

    The management of patients with brain metastases from breast cancer continues to be a major clinical challenge. The standard initial therapeutic approach depends upon the size, location, and number of metastatic lesions and includes consideration of surgical resection, whole-brain radiotherapy, and stereotactic radiosurgery. As systemic therapies for control of extracranial disease improve, patients are surviving long enough to experience subsequent progression events in the brain. Therefore,...

    Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized. PMID:27561800

    Full Text Available Wilms’ tumor (nephroblastoma is the most common renal tumor in children. It is uncommon in adolescent and skeletal metastasis at the time of presentation is even rare. The present case is a rare monophasic blastemal variant of Wilms’ tumor presenting with multiple skeletal metastases in a young female. We report a case of 23-year-old female presented with severe low backache and colicky right loin pain of 1 month and constant dull aching left upper arm pain of 20 days duration. Contrast-enhanced computed tomography (CECT abdomen revealed heterogeneously enhancing soft tissue density mass with central nonenhancing areas arising from the upper pole of the right kidney. Whole body 18F-Sodium Fluoride (NaF Positron emission tomography– computed tomography (PET/CT bone scintigraphy revealed multiple skeletal metastases. The patient underwent right radical nephrectomy and the tumor was confirmed as adult Wilms’ tumor by histopathology and immunohistochemistry. Skeletal metastasis may be the first presentation in a case of adolescent Wilms’ tumor, and this possibility should be considered when an adolescent patient presents with flank pain and a renal mass. The clinical course of adult Wilms’ tumor with blastemal component is very aggressive with high chances of recurrence and mortality

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

    2012-01-01

    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 meaningful for regulatory approval, and the Food and Drug Administration issued a letter concurring with the committee's recommendation. The role of denosumab in prostate cancer will continue to evolve either as monotherapy or in

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

    Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the body's neuroendocrine system. Rectal high grade NEC (HG-NEC) constituting less than 1% of colorectal cancers can cause large ovarian metastasis that may be the initial presenting complaint. Ovarian Krukenberg tumor from a primary rectal HG-NEC is a very unusual and exceedingly uncommon differential diagnosis for secondary ovarian malignancy. This case report describes one such extremely rare case of a woman who had presented to the gynecology department with features suggestive of ovarian malignancy and was ultimately diagnosed to have Krukenberg tumor originating from neuroendocrine cancer of rectum. We felt this is a good opportunity to spread more light on neuroendocrine neoplasms that are very rare in gynecological practice. PMID:27293931

  2. Thyroid metastases in renal cell cancer: two case reports

    International Nuclear Information System (INIS)

    Non-thyroid cancers rarely metastasize to the thyroid gland. Metastases can be divided into those with clinical expression and those identified at necropsy. Symptom producing thyroid metastases are usually due to a primary renal cell cancer. We report two cases of thyroid metastasis of a clear cell renal carcinoma. In the first case, an 82-year-old woman presented with an enlarged thyroid metastasis and identification of recurrent renal cell carcinoma which had been treated by radiotherapy 24 years earlier. After radiotherapy for a concomitant pulmonary metastasis, the patient is in good general health with no signs of recurrence. In the second case, increased thyroid volume led to signs of compression in a 71-year-old-man. The pathology report after left lobular thyroidectomy suggested trabecular adenoma or metastasis of a clear-cell primary tumour. Abdominal CT-scan revealed a 3.5 cm tumour found to be a clear-cell renal carcinoma at nephrectomy. Another osteolytic metastasis to the femur was also observed three months after surgery. The patient is in good health 15 months after the initial diagnosis. The significance of thyroid metastasis of renal cell carcinoma would vary according to the different cases reported in the literature with survival ranging from 32 months to 3-7 years after surgical exeresis. Prognosis would thus not appear to be as poor as for thyroid metastasis from other primary tumours. (authors). 24 refs

  7. Skeletal-related events in urological cancer patients with bone metastasis. A multicenter study in Japan

    International Nuclear Information System (INIS)

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

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

    Full Text Available Lung cancer is the most common cause of cancer related mortality in men and women. Approximately 15% of lung cancers are small cell type. Chemotherapy and radiation are the mainstay treatments. Currently, the standard chemotherapy regimen includes platinum/etoposide. For extensive small cell lung cancer, irinotecan and cisplatin have also been used. Patients with relapsed small cell lung cancer have a very poor prognosis, and the morbidity increases with brain metastases. Approximately 10%–14% of small cell lung cancer patients exhibit brain metastases at the time of diagnosis, which increases to 50%–80% as the disease progresses. Mean survival with brain metastases is reported to be less than six months, thus calling for improved regimens. Here we present a case series of patients treated with irinotecan for progressive brain metastases in small cell lung cancer, which serves as a reminder of the role of systemic chemotherapy in this setting.

    The literary data and the author's material (132 patients with peripheral lung cancer and 112 patients with central lung cancer) are used to develop a technique for calculated table diagnosis of lung cancer metastases to regional lymph nodes. The results of table diagnostics are compared with therapeutic and computer diagnostics. The above technique improves the diagnostics of lung cancer metastases to regional lymph nodes by 20%. However, the results of table diagnostics of metastases are somewhat worse (2.8-4.4 %) than those of computer diagnosis. 5 refs.; 3 tabs

  16. Stereotactic radiosurgery with the gamma knife for brain metastases in patients with lung cancer

    International Nuclear Information System (INIS)

    Between February 1992 and April 1993, six patients with lung cancer were treated with gamma knife radiosurgery for brain metastases. Five patients had adenocarcinoma, and one patient had small cell carcinoma. Two patients had solitary metastases, and four patients had multiple metastases. Twelve metastases were treated with the gamma knife (peripheral dose between 12 Gy and 25 Gy). After radiosurgery, three complete and eight partial responses were achieved, which resulted in an overall response rate of 92%. In two patients, histological studies showed that few viable cells were surrounded by necrosis. Neurological status improved in all patients, and none died of complications. However, four of six patients later developed new intracranial metastases outside the treatment field. These data suggest that radiosurgery with the gamma knife is effective against brain metastases in patients with lung cancer, especially when the lesions are deep in the brain. (author)

    Full Text Available Brown tumors of bone are highly vascular, lytic bone lesions representing a reparative cellular process rather than a neoplastic process usually seen in patients with hyperparathyroidism. These tumors can behave aggressively and be destructive. We report a 49-year-old male patient who was admitted to our hospital with a long-term history of right shoulder and right hip pain. Multiple lytic and destructive bone lesions were found in X-ray graphy and CT images. These bone lesions mimicked multiple skeletal metastatic lesions and seemed to be those of the terminal stage of malignancy. PET scan was requested for the evaluation of FDG uptake of these lesions and to search the unknown primary tumor site. Positron emission tomography/computed tomography (PET/CT images showed multiple hypermetabolic malignant or metastatic FDG avid bone lesions in skeletal system. However the biopsy results revealed no signs of malignancy and laboratory data showed elevated serum calcium, alkaline phosphatase, parathyroid hormone, low serum phosphate and parathyroid scintigraphy was performed. Adenoma in the left parathyroid gland was seen with Tc-99m MIBI parathyroid scintigraphy. Pathological results confirmed the diagnosis of parathyroid adenoma. Brown tumor is the potential cause of false-positive result in evaluation of a patient for unknown primary tumor or skeletal metastases with PET/CT imaging.

    Full Text Available Abstract Introduction Osseous tuberculosis can be present with unifocal or multifocal bony involvement. Although multifocal involvement of the skeletal system in areas where tuberculosis is endemic is not a rare presentation, its exact prevalence is not well known. A case of atypical skeletal tuberculosis mimicking multiple secondary metastases on radiologic and scintigraphic imaging is presented to emphasize the contribution of bone scintigraphy in the assessment of osseous tuberculosis in typical and atypical presentations. Case presentation A 73-year-old cachectic Asian man (Iranian presented with a general feeling of being unwell and an acute loss of vision in his left eye accompanied by a severe headache. A Tc-99 m-methylene diphosphonate bone scan demonstrated multiple regions of intense activity in the appendicular and axial skeleton, suggesting metastatic involvement. Tumor markers (PSA, CA125, CA 19-9 and AFP were within normal ranges. Based on clinical presentation and laboratory, radiological and scintigraphic findings, a presumptive diagnosis of tuberculosis was made. Quadruple antituberculous chemotherapy was consequently started and the patient later showed marked improvement. Conclusion Scintigraphic bone scanning should be kept in mind when assessing bone pain in patients at a high risk of tuberculosis infection or reactivation. We present this unusual case of multifocal skeletal tuberculosis, and stress the related clinical and diagnostic points with the aim of stimulating a high index of suspicion that could facilitate early diagnosis and appropriate treatment.

    Cancer patients with severe renal dysfunction represent a challenge for the physician. This is the first case report on the use of denosumab in a dialysis patient with bone metastases. We present the clinical case of a 45-year-old woman who had hepatorenal polycystic disease, diagnosed during childhood, and stage IV chronic kidney failure at the time of breast cancer diagnosis. Three years after surgery plus adjuvant hormonal therapy she suffered a further worsening of renal function, requiring dialysis, and very advanced bone metastasis in the hip with severe pain. As pamidronate was the only bone agent available in the center, she received it for 4 months (before a dialysis session), during which time the bone metastases stabilized. In March 2014, the patient switched to denosumab (which had become available in the center), and continued with hormone therapy. Seven months after denosumab initiation, the patient had almost complete pain relief, and the bone metastases exhibited radiological improvement. The tolerability was excellent, without any related adverse event. There were no changes in albumin-adjusted serum calcium, serum phosphorus, and intact parathyroid hormone, except for a transient and mild hypocalcemia at 3 months and an increase in intact parathyroid hormone levels, which required adjustment of vitamin D analog dose. Denosumab can be administered to prevent skeletal-related events in patients with bone metastasis from solid tumors and severely impaired renal function, even in those requiring dialysis. In this particular patient, the safety was good. PMID:26813866

  20. Comparative study between characteristics of the lung cancer, breast cancer and esophageal cancer distal bone metastases

    International Nuclear Information System (INIS)

    Objective: To compare the characteristics of the distribution of bone metastases in lung cancer, breast cancer and esophageal cancer. Methods: SPECT bone imaging of the entire body was performed after the injection of 99Tcm-methylene diphosphonate (99Tcm-MDP) in 454 cases. Analyzed the distribution of metastatic bone lesions in upper limbs' middle and distal or the pelvis and lower limbs and the distinction of metastatic bone lesions between different diseases were distinguished. Results: Of all the 454 patients, 130 cases showed abnormal radionuclide concentration in the region of upper limbs' middle and distal or the pelvis and lower limbs. One thousand three hundreds and three metastatic bone lesions were found in all the patients [893 were in lung cancer (64.4%), 36 1 were in breast cancer (27.7%) and 103 were in esophageal cancer (7.9%)]. Radioactive uptake in rotor area of femur lesions in these diseases was demonstrated to be of large proportion. Conclusions: The result of 99Tcm-MDP bone imaging shows that the distribution of the metastatic bone lesions in lung cancer, breast cancer and esophageal cancer vary from place to place. (authors)

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

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

    Breast cancer patients typically develop brain metastases years after their initial diagnosis. During this clinical latency, cancer cells must evolve and adapt to the neural microenvironment to colonize. We hypothesized that breast cancer cells may assume brain-like properties to survive in the brain. Our results suggest that metastases overexpress many variables related to the γ-aminobutyric acid (GABA) and were able to proliferate by metabolizing GABA as a biosynthetic energy source. The ex...

  8. Computed tomography in brain metastases of colorectal cancer

    International Nuclear Information System (INIS)

    Metastatic brain tumors from colorectal cancers are relatively rare. In previous reports, the incidence ranged from 3 to 5 percent of all metastatic brain tumors. We report 7 cases of metastatic brain tumors from colorectal cancers. The time interval from the diagnosis of the primary tumors to the brain metastasis was 3 years on the average. Metastasis to the lung and liver were also found in 6 cases at the time of the diagnosis of the brain metastasis. The CEA levels in the serum were highly elevated in all cases. Solitary metastasis was found in all cases; cancers tend to metastasize in the deep area of the cerebrum or cerebellum. On a plain CT scan, tumors were demonstrated as ring-type, with a high-density mass, and ring-like enhancement was seen in 6 cases. Prognosis was very poor in most cases. The median survival time from diagnosis of brain metastasis was 4.5 months in the 2 cases with surgery and 3.5 months in the 4 cases without surgery. (author)

  12. Brain metastases in lung cancer. Impact of prognostic factors on patient survival

    International Nuclear Information System (INIS)

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

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

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

    Lung metastasis is frequent in rectal cancer patients and has a poor prognosis, with an expected three-year survival rate of about 10%. Though western medicine has made great strides in the curative resection of liver metastases, resection of lung metastases has lagged far behind. Many preclinical studies have suggested that herbal treatments block metastasis, but few clinical studies have addressed this topic. We present the case of a 57-year-old Asian male with lung metastases from rectal cancer. He first underwent resection of the primary lesion (stage IIA, T3N0M0) and six cycles of adjuvant chemotherapy. Unfortunately, lung metastases were confirmed about one year later. Palliative chemotherapy was begun, but his disease continued to progress after three cycles and chemotherapy was halted. The patient was exclusively treated with herbal medicine-standardized allergen-removed Rhus verniciflua stokes extract combined with Dokhwaljihwang-tang (Sasang constitutional medicine in Korea). After seven weeks of herbal medicine treatment, the lung metastases were markedly improved. Regression of lung metastases has continued; also, the patient's rectal cancer has not returned. He has been receiving herbal medicine for over two years and very few side effects have been observed. We suggest that the herbal regimen used in our patient is a promising candidate for the treatment of lung metastases secondary to rectal cancer, and we hope that this case stimulates further investigation into the efficacy of herbal treatments for metastatic colorectal cancer patients.

    Peter J Mazzone

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

  19. Disseminated osteomyelitis or bone metastases of breast cancer. 18F-FDG-PET/CT helps unravel an unusual presentation

    International Nuclear Information System (INIS)

    We present a case wherein striking 18F-FDG-PET/CT findings initially considered consistent with recurrent disseminated skeletal metastases of breast cancer were later identified as an unusual presentation of disseminated chronic pyogenic osteomyelitis with Staphylococcus aureus and warneri identified on microbiological culture. A 76-year-old female with previous history of breast cancer presented with a 6-month history of pyrexia, myalgia and weight loss. Besides neutrophilia and elevated C-reactive protein, other blood indices, cultures and conventional imaging failed to identify the cause of pyrexia of unknown origin (PUO). 18F-FDG-PET/CT demonstrated multiple widespread foci of intense FDG uptake in lytic lesions throughout the skeleton. Coupled with previous history of malignancy, findings were strongly suggestive of disseminated metastases of breast cancer. Through targeting an FDG avid lesion, 18F-FDG-PET/CT aided CT-guided biopsy, which instead identified the lesions as chronic pyogenic osteomyelitis. Following prolonged antibiotic therapy, repeat 18F-FDG-PET/CT demonstrated significant resolution of lesions. This case demonstrated an unusual presentation of disseminated osteomyelitis on 18F-FDG-PET/CT and highlighted the use of 18F-FDG-PET/CT as a trouble shooter in PUO but demonstrated that unusual presentations of benign or malignant pathologies cannot always reliably be differentiated on imaging alone without aid of tissue sampling. Furthermore, this case highlights the potential role 18F-FDG-PET/CT could provide in assessing response to antibiotic therapy. (author)

    International Nuclear Information System (INIS)

    Objective: To assess the clinical efficacy and prognostic factors of Stereotactic Radiotherapy (SRT) for patients with brain metastases (BM) from lung cancer. Methods: From March 1995 to July 2006, 152 consecutive patients with BM from lung cancer were treated by SRT, among them,59 patients received SRT alone, 40 patients received SRT plus whole brain radiotherapy (SRT + WBRT), and 53 patients were salvaged by SRT after WBRT (salvaged group). Log-rank method was used for univariate analyses. Cox regression model was used for multivariate analyses. Results: The follow-up rate was 97.4%. The half year and 1 year local control rate for SRT alone group, SRT + WBRT group and salvage group were 96. 0% and 93.4%, 94.2% and 90.8%, 81.7% and 77.5% (χ2 = 5.39, P = 0.068)respectively. The 1-, 2-, 5 year survival rate for SRT alone group, SRT + WBRT group and salvage group were 47.4%, 23.7%, 8.5%; 55.0%, 20.0%, 0%; 41.5%, 7.5%, 1. 9%, respectively. The median overall survival or each group was 11, 12, 11 months (χ2 = 4.08, P = 0130). The univariate analysis showed that the interval between diagnosis of lung cancer and BM, KPS, thoracic surgery, GPA grade, RPA class, system disease stable were significant prognostic factors (χ2 =11.97, 5.91, 15.48, 14.48, 15.86, 17.36, P = 0.001, 0.015, 0.000, 0.000, 0.000, 0.000). The multivariate analysis showed that the RPA class , thoracic surgery were the independent prognostic factors (χ2 = 21.02, 8.18, P = 0.000, 0.004). KPS score less than 70, 80 ,90 for all patients before SRT and 3 months later after SRT were 48.7%, 33.6%, 17.8% and 27.0%, 46.7%, 26.3% respectively (t = 7.16, P=0.000). Conclusions: A definitive benefit of SRT in the treatment BM from lung cancer is observed; there is no difference of survival among SRT alone, SRT + WBRT and salvage treatment. SRT can improve the patients' KPS score. Thoracic surgery, RPA class were the independent prognostic factors for patients with BM from lung cancer. (authors)

    A multicentre observational study was conducted by the Italian Association of Nuclear Medicine between 1996 and 1998. Twenty-nine Nuclear Medicine Departments participated. The aims of the study were to systematically evaluate the efficacy, toxicity and repeatability of radionuclide therapy of painful bone metastases (RTBM) in a large number of patients and to assess its incidence in patients with prostate cancer. Out of 818 treatments performed with a single i.v. dose of 148 MBq of strontium-89 chloride or 1,295 MBq of rhenium-186 hydroxyethylidene diphosphonate (HEDP), 610 could be evaluated (527 with {sup 89}Sr and 83 with {sup 186}Re-HEDP). Eighty-one patients received multiple (up to five) RTBM. The total number of retreatments was 100. Patients were followed up for a period of 3-24 months. Results, assessed according to pain relief and consumption of analgesic drugs, were expressed at four levels: 1, no response; 2, mild response; 3, good response; 4, excellent response. Responses were: level 1 in 19%, level 2 in 21.3%, level 3 in 33.3% and level 4 in 26.4% of cases. Retreatments showed significantly (P<0.01) worse responses (48% levels 3+4), in comparison to first RTBM. Duration of palliation was 5.0{+-}3.5 months, and was longer in cases of excellent response, in first RTBM, in patients with limited metastases and when {sup 89}Sr was used. Better responses were found in cases of limited skeletal disease, under good clinical conditions, when life expectancy exceeded 3 months, and in radiologically osteoblastic or mixed bone lesions. The only statistically significant predictive factor was life expectancy (P<0.001). Flare phenomenon (14.1% of cases) did not correlate with the response. Haematological toxicity (mild to moderate in most cases) mainly affected platelets, and was observed in 25.5% of cases overall and in 38.9% of retreatments. RTBM did not seem to prolong life, though in some cases scintigraphic regression of bone metastases was observed. The two

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

    Liver metastases in colorectal cancer patients decreases the expected 5 year survival rates by a factor close to nine. It is generally accepted that resection of liver metastases should be attempted whenever feasible. This manuscript addresses the optimal therapeutic plan regarding timing of resection of synchronous liver metastases and the use of chemotherapy in combination with resection of synchronous metachronous liver metastases. The aim is to pool all published results in order to attribute a level of evidence to outcomes and identify lacking evidence areas. A systematic search of guidelines, reviews, randomised controlled, observational studies and updating a meta-analysis was performed. Data were extracted and analysed. Data failed to demonstrate an effect of timing of surgery or use of chemotherapy on overall survival. Concomitant resection of liver metastases and the primary tumour may result in lower postoperative morbidity. Systemic peri-operative chemotherapy may improve progression free survival compared to surgery alone. PMID:25666309

  6. Does colon cancer ever metastasize to bone first? a temporal analysis of colorectal cancer progression

    International Nuclear Information System (INIS)

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

    Different therapeutic options for the management of prostate cancer (PC) have been developed, and some are successful in providing crucial improvement in both survival and quality of life, especially in patients with metastatic castration-resistant PC. In this scenario, diverse combinations of radiopharmaceuticals (for targeting bone, cancer cells and receptors) and nuclear medicine modalities (e.g. bone scan, SPECT, SPECT/CT, PET and PET/CT) are now available for imaging bone metastases. Some radiopharmaceuticals are approved, currently available and used in the routine clinical setting, while others are not registered and are still under evaluation, and should therefore be considered experimental. On the other hand, radiologists have other tools, in addition to CT, that can better visualize bone localization and medullary involvement, such as multimodal MRI. In this review, the authors provide an overview of current management of advanced PC and discuss the choice of diagnostic modality for the detection of metastatic skeletal lesions in different phases of the disease. In addition to detection of bone metastases, the evaluation of response to therapy is another critical issue, since it remains one of the most important open questions that a multidisciplinary team faces when optimizing the management of PC. The authors emphasize the role of nuclear modalities that can presently be used in clinical practice, and also look at future perspectives based on relevant clinical data with novel radiopharmaceuticals.

  9. Clinical effect of percutaneous radiofrequency ablation for residual lung metastases from breast cancer after systemic chemotherapy

    International Nuclear Information System (INIS)

    Objective: To determine the clinical effect of Radiofrequency Ablation (RFA) for residual lung metastases from breast cancer after systemic chemotherapy. Study Design: An experimental study. Place and Duration of Study: The Second Affiliated Hospital of Soochow University, Suzhou, Fudan University Shanghai Cancer Center, Shanghai, China, from January 2008 to October 2014. Methodology: Thirty-five breast cancer patients with 67 pulmonary metastases were involved in this study. All lesions were treated by RFA and followed by CT-scan. Primary endpoint of this clinical study was local control; secondary endpoints were overall survival and treatment-related toxicities. Results: Complete Response (CR) was observed in 59 lesions, with Partial Response (PR) in 4 lesions, Stable Disease (SD) in 1 lesion and Progression Disease (PD) in 3 lesions. The lesion diameter > 2 cm was related to poor local control (p=0.04). The median Overall Survival (OS) was 33 months (95%CI: 21.6 - 44.4). One, 2-, and 3-year OS rates were 88.6%, 59.3% and 42.8% respectively. The mumber of pulmonary metastases (2), the diameter of lesion (> 2 cm) and coexisting with liver metastases were significantly correlated to poor OS by multivariate analysis. Log-rank test showed statistically significant difference of OS in diameter of lesion and coexisting with other metastases. Conclusion: RFA is a promising treatment option for patients with residual lung metastases from breast cancer after systemic chemotherapy in selected patients. (author)

    Full Text Available Development of an optimal algorithm of ray diagnostic examinations in the case of colorectal cancer liver metastases is extremely important. The paper reviews the literature on the diagnosis of colorectal cancer liver metastases. Diagnosis of liver metastases is based on imaging techniques that allow you to assess the condition of the liver, the number and size of lesions and the number of parameters on which the patient is suitable for radical surgery. Described ultrasound (US, computed tomography (CT and magnetic resonance imaging (MRI semiotics of liver metastases, and reflect additional information that can be obtained using beam methods of research, which is of great importance in determining resectability and preoperative planning of surgery. We consider differential diagnosis with benign tumors of the liver. The value and priority of such methods of radiation diagnosis as ultrasound with contrast, CT and MRI contrast agents, is widely debated among experts.

    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.

  17. Calcifying liver metastases. Computed tomography imaging and incidence of primary colorectal cancer

    International Nuclear Information System (INIS)

    A total of 24 patients with liver metastases of the calcifying type were detected during CT scan imaging for cancer of different primary origin (colorectal, ovarian, mammary, gastric, prostatic melanoma). These calcifying metastases represented 27% of the 89 liver metastases cases detected, and the incidence of a colorectal origin for these calcifying lesions (20% of cases) appears to be highly significant, their number being relatively larger than reported in previous studies. Identification of liver calcifications of possible diagnostic importance requires a two-stage CT scan investigation, before and after bolus. Paraclinical examinations should be directed selectively towards the digestive tract when the primary tumor is unknown

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

  4. Efficacy and safety of a modular multi-modal exercise program in prostate cancer patients with bone metastases: a randomized controlled trial

    International Nuclear Information System (INIS)

    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 treatment of lymph node metastases involving the carotid artery is controversial. The aim of the present study was to determine the outcomes of head and neck cancer patients with radiographic carotid artery involvement in neck metastases. A total of 27 patients with head and neck cancer and radiologically diagnosed advanced metastases involving the common carotid artery or internal carotid artery were enrolled. All patients underwent a primary or salvage neck dissection and surgical carotid peeling. The oncological outcome and survival of all patients were analyzed. Loco-regional control was observed in 13 of the 27 patients (48.1%). During follow-up, five patients (18.5%) developed second primaries and 11 (40.7%) developed distant metastases. The survival time was poor independent of regional control. The median overall survival was 1.55 years and disease-free survival was 0.71 year. Radiographic carotid artery involvement in neck metastases in head and neck cancer appears to correlate with a poor long-term prognosis, with a high rate of distant metastases despite loco-regional control.

    2015-03-01

    Full Text Available Background: Small cell lung cancer is an aggressive subtype of lung cancer whereby about one-third of cases are complicated with bra­in metastases. However, cerebellar metastases are uncommon and contribute to less than 10% of brain metastases. Case: We report a 76-year-old Malay male, an active smoker who presented with dyspnea and occasional cough with hemoptysis for one week. He also pre­sented with headache and constitutional symptoms of malignancy. Clinical examination suggested the presence of right upper chest patholo­gy and positive left cerebellar signs. His condition deteriorated two days later and he passed away after failed attempts at resuscitation. Chest radiograph showed right upper lobe collapse, and brain magnetic resonance imaging showed metastatic lesion in the left cerebellum extending to the right cerebellum. Post-mortem findings revealed small cell lung cancer with cerebellar metastases. Conclusion: Small cell lung cancer patients with brain metastases deteriorate very rapidly, and the management is mainly supportive. Primary prevention through education is the best way to reduce the incidence of lung cancer. In addition, secondary prevention and screening should be undertaken at earlier stages of the disease, as some studies have shown that combined chemotherapy and radiotherapy improve prog­nosis of malignancies detected at early stage.

  13. Results of radioiodine therapy in patients with pulmonary metastases of differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Factors affecting the effect of 131I treatment and survival after pulmonary metastases in patients with differentiated thyroid cancer, were studied. Between 1984-1999, pulmonary metastases was observed in 51 out of 153 patients with differentiated thyroid cancer at our institution. Of these 41 patients had papillary and 10 follicular thyroid cancer. There were 37 females and 14 males with mean age (±S.D.) of 50.5±19.0 years. These 51 patients were subjected to 131I therapy. The effect of 131I treatment and the prognostic values of the following variables were examined: sex, age at the time of 131I treatment, histologic type of cancer, size of pulmonary metastases on CT, total-body scintigraphy with 201Tl and 131I, serum thyroglobulin levels and presence of metastases in distant sites other than lung. The effect of 131I treatment was evaluated by means of changes in the number and size of metastatic shadows on chest CT and by serum thyroglobulin levels. The minimum duration of follow-up was 12 months. Therapeutic 131I dose scans revealed detectable uptake in 25 of 51 patients. Therapeutic 131I dose uptake was achieved more frequently in patients under 40 years of age and in those with follicular cancers. Of the 51 patients, 13 were evaluated to be treated successfully. Those under 40 years of age, with 131I up-take in the lung and presence of other metastases showed a good response to treatment than others. Follicular cancer showed a more significant association with coarse type of lung metastases (>5 mm in diameter on chest CT) and good 131I uptake than papillary cancer. Of all the variables studied, the best prognosis for survival was demonstrated by increased 131I uptake in pulmonary metastases. These results indicate that age, 131I uptake and presence of other metastases are important factors in predicting the effect of 131I treatment for pulmonary metastases of differentiated thyroid cancer.

  14. Radiation therapy for brain metastases from breast cancer by histological classification

    International Nuclear Information System (INIS)

    One hundred thirteen patients with metastatic brain tumor from breast cancer who were treated with external irradiation between 1989 and 1997 at Cancer Institute Hospital were studied. The patients were all histopathologically proven to have invasive ductal carcinoma (scirrhous type 54 cases, papillotubular type 18, solid-tubular type 41). The patients were evaluated for efficacy and histopathological subtypes. The time interval between the diagnosis of breast cancer and brain metastases was 53.6 months for the scirrhous type, 75.0 months for the papillotubular type, and 35.5 months for the solid-tubular type. The time interval between the diagnosis of initial distant metastases and brain metastases was 14.3 months for the scirrhous type, 22.5 months for the papillotubular type, and 12.5 months for the solid-tubular type. Efficacy rates (CR+PR) for external irradiation of the brain metastases were 40.0% for the scirrhous type, 66.7% for the papillotubular type, and 36.6% for the solid-tubular type. The papillotubular type had a favorable efficacy rate compared with the other two types. Median survival time (MST) from the start of treatment for brain metastases and one-year survival rate were 5 months and 11.1% for the scirrhous type, 7 months and 41.5% for the papillotubular type, and 4 months and 28.3% for the solid-tubular type, respectively. No statistically significant difference between survival rates was observed among the histopathological types. Univariate analysis showed performance status, number of metastatic tumors, and existence of extracranial metastases without bony metastasis to be significantly related to prognosis. Multivariate analysis showed only extracranial metastases without bony metastases to be related to prognosis. (author)

    2010-01-01

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

A risk calculator that incorporates many factors to evaluate an individual's risk of harbouring synchronous metastases would be useful to adapt cancer management. Patients and Methods: Patients with primary diagnosis of BC were identified from three institutional databases sharing homogeneous work-up recommendations. A risk score for synchronous metastases was estimat...

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of 89Sr 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 89Sr. 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 (χ2=0.78, P>0.05). The Karnofsky score was significantly improved in both groups (t=2.46, P89Sr treatment was good, and the quality of life was improved in patients with multiple bone metastases breast or prostate cancer.

    Of ophthalmic involvement from metastatic breast cancer, extraocular/intraorbital metastases are extremely rare. External beam radiotherapy has been a mainstay palliation for symptomatic orbital metastases. We present a case of bilateral orbital metastases from breast cancer successfully treated with stereotactic radiotherapy (SRT). A 38-year-old woman presented with decreased vision in the right eye for 3 weeks. Eight months previously, she underwent whole-brain radiotherapy for multiple brain metastases from breast cancer. Visual acuity was hand motion, and the eyelid closed incompletely in the affected eye. Computed tomography scans showed a 3-cm extraconal mass in the right orbit. She underwent temporary tarsorrhaphy followed by SRT. A total dose of 39 Gy was delivered to the right orbital mass in three daily fractions. Four months later, her visual function was normal in both eyes and the right orbital mass disappeared. A new lesion was detected in the left orbit. She underwent SRT for the left orbital lesion using the same dose-fractionation schedule. No radiation-related toxicities were observed. She died 19 months after the first SRT. Our case suggests that SRT may be an effective and safe treatment option in patients with orbital metastases from breast cancer. PMID:21999613

  20. Intracranial arterial infusion chemotherapy for lung cancer complicated by brain metastases: a clinical observation

    International Nuclear Information System (INIS)

    Objective: T evaluate the efficacy of intracranial arterial infusion chemotherapy in treating advanced lung cancer with brain metastases and to discuss the factors influencing prognosis. Methods: From September 2007 to August 2008, a total of 27 patients of lung cancer with brain metastases received intracranial arterial infusion chemotherapy. This procedure was performed every 4 weeks for three times in succession. Follow-up brain MRI was regularly performed at intervals of eight weeks after the treatment in order to evaluate the therapeutic efficacy, which was conducted until the disease became worse or the patient could tolerate the drug toxicity no longer. Results: All 27 cases were treated 3 times at least, and one case received 7 times. Of the 27 cases, partial response was obtained in 15 (55.6%), stable condition in 8 (29.6%) and deterioration in 4 (14.8%), although no one showed complete alleviation. The effective rate for intracranial lesions was 55.6% (15/27) and the 85.2% of lesions (23/27) were brought under control. Overall median survival time was 7 months. The 6-month survival rate and 1-year survival rate were 81.5% and 14.8%, respectively. Conclusion: Intracranial arterial infusion chemotherapy is one of the most effective methods for the treatment of lung cancer associated with brain metastases. Karnofsky performance status ≥ 60 and absent of extra cranial metastases are good prognostic factors for lung cancer patients with brain metastases. (authors)

  1. Treatment by 131I of differentiated thyroid cancers pulmonary metastases in child. About one case

    International Nuclear Information System (INIS)

    Differentiated thyroid cancers, rare in children, are often at the pulmonary metastases stage. Because of the diffuse character of these metastases, the treatment consists exclusively in iodine 131. We report the case of a girl in whom a papillary carcinoma was diagnosed at the age of five. The post surgery scanning revealed the presence of a pulmonary miliaria. The patient received 7 cures of iodine 131, with a cumulative activity of 650 mCi. These cures allowed to get a remission labeled on the scanning cleaning with iodine 131 as well as the rate of thyroglobulin became undetectable. The follow-up after five years does not detect neither sign of recurrence, nor sign of pulmonary fibrosis, nor second cancer. Ira-therapy stays the preferred treatment for pulmonary metastases of which effectiveness can reach 80%. The risk to develop second cancers is low. Less frequent treatments reduce the risk of pulmonary fibrosis. (N.C.)

    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.

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

    Breast cancer brain metastases remain a significant clinical problem. Chemotherapy is ineffective and a lack of treatment options result in poor patient outcomes. Targeted therapeutics have proven to be highly effective in primary breast cancer, but lack of molecular genomic characterization of metastatic brain tumors is hindering the development of new treatment regimens. Here we contribute to fill this void by reporting on gene copy number variation (CNV) in 10 breast cancer metastatic brai...

    Metastasized rectal cancer has long been considered incurable. During recent years, the treatment of rectal cancer patients has been improved, and nowadays, a subgroup of patients might even be cured. The aim of this study was to investigate the optimal timing of treatment in a multimodal therapy schedule in order to see whether the addition of bevacizumab (Avastin) to conventional chemotherapy was effective. The study included 39 patients with metastatic rectal cancer between 2009 and 2011, ...

  7. HSV-1 as a novel therapy for breast cancer meningeal metastases.

    Science.gov (United States)

    Kuruppu, D; Tanabe, K K

    2015-10-01

    Meningeal metastasis is a fatal complication of breast cancer that affects 5-8% of patients. When cancer cells seed in the meninges, their subsequent growth results in severe neurological complications involving the cranial nerves, cerebrum and spinal cord, limiting life expectancy to less than 4 months. The incidences of meningeal metastases increase with prolonged lifespan resulting from treatment advances for primary breast cancer and their metastases. Currently, there is no cure. Aggressive multimodal therapies such as radiation and chemotherapy (intra-cerebrospinal fluid (CSF) and systemic) are ineffective. Therapeutic agents are often quickly cleared from the CSF, while higher doses that can achieve a therapeutic response are highly toxic. The secure guarding of the subarachnoid space by the blood-brain barrier on one side and the blood-CSF barrier on the other prevents chemotherapy from reaching cancer cells in the meninges. These challenges with treating meningeal metastases highlight the urgent need for a new therapeutic modality. An ideal treatment would be an agent that avoids rapid clearance, remains within the CSF, reaches the meninges and selectively destroys tumor cells. Replication conditional oncolytic herpes simplex virus type 1 (HSV-1) may be effective in this regard. Viral oncolysis, the destruction of cancer cells by replicating virus, is under clinical investigation for cancers that are unresponsive to current therapies. It is based on the model of multiple cycles of lytic virus replication in cancer cells that amplify the injected dose. The therapeutic potential of oncolytic HSV-1 for breast cancer meningeal metastases is discussed here. HSV-1 could be a potential novel treatment for meningeal metastases that can be translated to the clinic. PMID:26384139

  8. Efficacy and toxicity of Samarium-153-EDTMP locally produced in the treatment of painful skeletal metastases

    International Nuclear Information System (INIS)

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

  9. Treatment outcomes using CyberKnife for brain metastases from lung cancer

    International Nuclear Information System (INIS)

    We investigated the clinical outcomes following treatment using stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) for brain metastases from lung cancer. A total of 67 patients with 109 brain metastases from lung cancer treated using CyberKnife between 1998 and 2011 were retrospectively analyzed. SRS (median dose, 24 Gy) was used to treat 79 lesions, and 3-fraction SRT (median dose, 30 Gy) was used to treat 30 lesions. The median follow-up time was 9.4 months (range, 0.4 - 125 months). The 1-year local control rate was 83.3%, and the 1-year distant brain failure rate was 30.1%. The median survival time was 13.1 months, and the 1- and 3-year overall survival (OS) rates were 54.8% and 25.9%, respectively. On multivariate analysis, three factors were found to be statistically significant predictors of OS: (1) presence of uncontrolled primary disease [hazard ratio (HR) = 3.04; P = 0.002]; (2) Brinkman index (BI) ≥ 1000 (HR = 2.75; P = 0.007); and (3) pulmonary metastases (HR = 3.54; P = 0.009). Radionecrosis and worsening of neurocognitive function after radiosurgery were observed in 5 (7%) and 3 (4%) patients, respectively. Our results indicated that SRS/SRT for brain metastases from lung cancer was effective. Uncontrolled primary disease, high BI, and pulmonary metastases at treatment were significant risk factors for OS. (author)

  10. Changes in the renin angiotensin system during the development of colorectal cancer liver metastases

    International Nuclear Information System (INIS)

    Blockade of the renin angiotensin system (RAS) via angiotensin I converting enzyme (ACE) inhibition reduces growth of colorectal cancer (CRC) liver metastases in a mouse model. In this work we defined the expression of the various components of the RAS in both tumor and liver during the progression of this disease. Immunohistochemistry and quantitative RT-PCR was used to examine RAS expression in a mouse CRC liver metastases model. CRC metastases and liver tissue was assessed separately at key stages of CRC liver metastases development in untreated (control) mice and in mice treated with the ACE inhibitor captopril (750 mg/kg/day). Non-tumor induced (sham) mice indicated the effect of tumors on normal liver RAS. The statistical significance of multiple comparisons was determined using one-way analysis of variance followed by Bonferroni adjustment with SAS/STAT software. Reduced volume of CRC liver metastases with captopril treatment was evident. Local RAS of CRC metastases differed from the surrounding liver, with lower angiotensin II type 1 receptor (AT1R) expression but increased ANG-(1-7) receptor (MasR) compared to the liver. The AT1R localised to cancer and stromal infiltrating cells, while other RAS receptors were detected in cancer cells only. Tumor induction led to an initial increase in AT1R and ACE expression while captopril treatment significantly increased ACE expression in the final stages of tumor growth. Conversely, captopril treatment decreased expression of AT1R and angiotensinogen. These results demonstrate significant changes in RAS expression in the tumor-bearing captopril treated liver and in CRC metastases. The data suggests the existence of a tumor-specific RAS that can be independently targeted by RAS blockade

  11. Amphiregulin and Epiregulin mRNA expression in primary colorectal cancer and corresponding liver metastases

    International Nuclear Information System (INIS)

    Amphiregulin (AREG) and Epiregulin (EREG), ligands of EGFR, are reported to be predictive biomarkers of colorectal cancer patients treated with Cetuximab, an anti-EGFR antibody. The purpose of this study is to determine the correlation of AREG and EREG expression between primary colorectal cancer and corresponding liver metastases. One hundred twenty colorectal cancer patients with liver metastases (100 with synchronous metastases, 20 with metachronous) were evaluated. No patients had ever received anti-EGFR antibody agents. AREG and EREG mRNA expression from both the primary tumor and liver metastases were measured using real-time RT-PCR. KRAS codon 12, 13 mutation status was analyzed by direct sequencing. Modest, but significant, correlations were observed between primary tumor and corresponding liver metastases in both AREG mRNA expression (Rs = 0.54, p < 0.0001) and EREG mRNA expression (Rs = 0.58, p < 0.0001). AREG and EREG mRNA expression was strongly correlated in both the primary tumor (Rs = 0.81, p < 0.0001) and the liver metastases (Rs = 0.87, p < 0.0001). No significant survival difference was observed between low and high AREG or EREG patients when all 120 patients were analyzed. However, when divided by KRAS status, KRAS wild-type patients with low EREG mRNA levels in the primary site showed significantly better overall survival rates than those with high levels (p = 0.018). In multivariate analysis, low EREG expression was significantly associated with better overall survival (p = 0.006). AREG and EREG expression showed a modest correlation between primary tumor and liver metastases. As EREG mRNA expression was associated with decreased survival, it is appeared to be a useful prognostic marker in KRAS wild-type patients who never received anti-EGFR therapy

  12. Treatment options in patients with small-cell lung cancer and brain metastases

    International Nuclear Information System (INIS)

    Small cell lung cancer (SCLC) accounts for some 20-25% of all lung cancers, with some 60-70% of patients presenting with the extensive stage (ES) of SCLC at the time of the diagnosis. Brain metastases are observed in 10-35% patients with ES SCLC, and 33% of them are asymptomatic. The main method of treatment in case of ES SCLC patients is cisplatin-containing systemic therapy. Radiotherapy is used as palliative treatment (primary tumour in chest, metastases localized in bones, brain or spinal cord) or as a prophylactic procedure (prophylactic cranial irradiation).The purpose of paper is to present the treatment possibilities in case of ES SCLC patients with brain metastases. Between 1995 and 2005 at the Oncology Centre in Krakow we evaluated 170 patients with SCLC in order to establish the stage of the disease recognising 39 cases (22.9%) with the extensive stage of the disease. The most frequent localizations of distant metastases were: the brain (11 patients, of whom 3 developed brain metastases without clinical symptoms), liver (10 patients), and bones (10 patients). Further analysis has been performed in the group of patients with brain metastases. In these patients treatment based on palliative irradiation of the whole brain and on chemotherapy according to the EP (etoposide and cisplatine) regimen. For cranial irradiation the dose of 20 Gy was given in 5 fractions. In 3 patients with brain metastases without clinical symptoms radiotherapy of brain was repeated after a 4-week interruption. These patients received 5-6 cycles of EP chemotherapy, followed by consolidation radiotherapy of the primary tumour region in the chest. Overall survival was estimated at 2 to 19 months (median: 8.9 months). In the subgroup of 3 patients with brain metastases without clinical symptoms we observed complete regression within the primary tumour region and of the brain metastases. These results were confirmed radiologically. In these patients disease-free survival of 5-9 months

  13. Pulmonary metastases of the thyroid differentiated cancer: role of iodine 131 in early detecting and treatment

    International Nuclear Information System (INIS)

    The detection of functional pulmonary metastases of differentiated cancer in thyroid is often done in the radiological stage and a 10 year survival is of the order of 50%. We have evaluated the results of a protocol based on to principles: 1. systematic administration of 3.7 GBq of iodine 131 after any total thyroidectomy; 2. repeated treatment by iodine 131 of functional metastases without fixed limit of cumulated activity. Five hundreds and nine differentiated cancers of thyroid were operated between 1970 and 1996. A total thyroidectomy was decided in 76% of cases followed by a iodine 131 therapy. Thirty two patients presented pulmonary metastases. This work refers to 20 patients in which the metastases were functional (fixating). These metastases were not visible on the thorax radiography in 11 patients (group 1) but visible in 9 patients (group 2). In group 1, the metastases were detected at initial treatment by iodine 131 in 11 patients (100%). Three patients had also an osseous metastasis. The average span of surveillance for this group is 9 years. The pulmonary fixation disappeared in 9 patients. A single decease has been recorded, due to a cervical recurrence. In group 2 the metastases were present at initial accounting examination in 8/9 patients. Four of them presented also osseous metastases. The treatment with iodine 131 was associated to a pulmonary metastasis-ectomy in 3 cases and to a surgery and/or osseous radiotherapy in 3 cases. A remission of the metastases was noted in all the patients as well as 2 healings. The average span survival was 8 years. A patient deceased 2 years after interrupting the treatment. The 10 year survival for the ensemble of this series, calculated by the Kaplan-Meier method, was 87%. In conclusion: 1. the therapy by iodine 131 after thyroidectomy allows the early diagnosis of functional metastases prior to the rise of thyroglobulin rate or appearance of radiological signs; 2. the repeated treatment by iodine 131 associated

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

  15. Metastases and Colon Cancer Tumor Growth Display Divergent Responses to Modulation of Canonical WNT Signaling.

    Directory of Open Access Journals (Sweden)

    Chandan Seth

    Full Text Available Human colon cancers commonly harbor loss of function mutations in APC, a repressor of the canonical WNT pathway, thus leading to hyperactive WNT-TCF signaling. Re-establishment of Apc function in mice, engineered to conditionally repress Apc through RNAi, resolve the intestinal tumors formed due to hyperactivated Wnt-Tcf signaling. These and other results have prompted the search for specific WNT pathway antagonists as therapeutics for clinically problematic human colon cancers and associated metastases, which remain largely incurable. This widely accepted view seems at odds with a number of findings using patient-derived material: Canonical TCF targets are repressed, instead of being hyperactivated, in advanced colon cancers, and repression of TCF function does not generally result in tumor regression in xenografts. The results of a number of genetic mouse studies have also suggested that canonical WNT-TCF signaling drives metastases, but direct in vivo tests are lacking, and, surprisingly, TCF repression can enhance directly seeded metastatic growth. Here we have addressed the abilities of enhanced and blocked WNT-TCF signaling to alter tumor growth and distant metastases using xenografts of advanced human colon cancers in mice. We find that endogenous WNT-TCF signaling is mostly anti-metastatic since downregulation of TCF function with dnTCF generally enhances metastatic spread. Consistently, elevating the level of WNT signaling, by increasing the levels of WNT ligands, is not generally pro-metastatic. Our present and previous data reveal a heterogeneous response to modulating WNT-TCF signaling in human cancer cells. Nevertheless, the findings that a fraction of colon cancers tested require WNT-TCF signaling for tumor growth but all respond to repressed signaling by increasing metastases beg for a reevaluation of the goal of blocking WNT-TCF signaling to universally treat colon cancers. Our data suggest that WNT-TCF blockade may be effective

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

    LENUS (Irish Health Repository)

    Jones, Claire

    2012-02-01

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

    OBJECTIVE:: The primary objective was to compare overall survival (OS) in patients with colorectal cancer (CRC) with nonresectable liver-only metastases treated by liver transplantation or chemotherapy. BACKGROUND:: CRC is the third most common cancer worldwide. About 50% of patients will develop...... metastatic disease primarily to the liver and the lung. The majority of patients with liver metastases receive palliative chemotherapy, with a median OS of trial patients of about 2 years, and less than 10% are alive at 5 years. METHODS:: Patients with nonresectable liver-only CRC metastases underwent liver...... transplantation in the SECA study (n = 21). Disease-free survival (DFS) and OS of patients included in the SECA study were compared with progression-free survival (PFS) and OS in a similar cohort of CRC patients with liver-only disease included in a first-line chemotherapy study, the NORDIC VII study (n = 47...

  18. Outcome of small cell lung cancer (SCLC) patients with brain metastases in a routine clinical setting

    International Nuclear Information System (INIS)

    Small cell lung cancer (SCLC) represents approximately 13 to 18% of all lung cancers. It is the most aggressive among lung cancers, mostly presented at an advanced stage, with median survival rates of 10 to12 months in patients treated with standard chemotherapy and radiotherapy. In approximately 15-20% of patients brain metastases are present already at the time of primary diagnosis; however, it is unclear how much it influences the outcome of disease according the other metastatic localisation. The objective of this analysis was to evaluate the median survival of SCLC patients treated by specific therapy (chemotherapy and/or radiotherapy) with regard to the presence or absence of brain metastases at the time of diagnosis. All SCLC patients have been treated in a routine clinical practice and followed up at the University Clinic Golnik in Slovenia. In the retrospective study the medical files from 2002 to 2007 were review. All patients with cytological or histological confirmed disease and eligible for specific oncological treatment were included in the study. They have been treated according to the guidelines valid at the time. Chemotherapy and regular followed-up were carried out at the University Clinic Golnik and radiotherapy at the Institute of Oncology Ljubljana. We found 251 patients eligible for the study. The median age of them was 65 years, majority were male (67%), smokers or ex-smokers (98%), with performance status 0 to 1 (83%). At the time of diagnosis no metastases were found in 64 patients (25.5%) and metastases outside the brain were presented in 153 (61.0%). Brain metastases, confirmed by a CT scan, were present in 34 patients (13.5%), most of them had also metastases at other localisations. All patients received chemotherapy and all patients with confirmed brain metastases received whole brain irradiation (WBRT). The radiotherapy with radical dose at primary tumour was delivered to 27 patients with limited disease and they got 4–6 cycles of

    According to the requirements of department of special drug, bureau of drug administration, Chinese Ministry of Health, the safety and efficiency of metastron injection solution imported from the Amersham Company, U.K. were tested. 27 patients were treated with metastron for metastatic bony pain (MBP). 2 cases were excluded by interrupted follow-up, the other 25 cases with metastatic prostate carcinoma, lung cancer, breast cancer were evaluated in a standard quantitative pain measurement before the treatment.Pain scores of these patients were between 6 - 16. 1.48 MBq/kg metastron was given intravenous. All the patients were observed at least 3 months. Pain score, immediate adverse reaction were observed . Results shown that clinical significant metastatic pain relief can be observed in most patients. Total efficiency was 72%, patients' life quality have been improved. There was mild decrease of white blood cell in 32% and platelet counts in 60% patients, but can recovered in most patients temporary except 1. In this case liver function abnormal was also appeared. Significant increased pain (flare) occurred in 55.5% patients after the injection, the flare up pain had been lasting 3 - 7 days, only one lasting more than 20 days. It was concluded that 89Sr is most effective in palliative therapy for MBP in-patient with prostate or breast carcinoma. In 94.4 % patients, the pain relief can lasted more than 3 months, but only one patient for 2 months. 7 cases had repeated the bone scan after therapy, but no significant changes can be observed. There by 89 Sr was safe and effective for the treatment of MBP

  1. Skeletal scintigraphy

    International Nuclear Information System (INIS)

    Skeletal scintigraphy, using phosphates or diphosphonates labeled with technetium 99m, is a sensitive method of detecting bone abnormalities. The most important and most frequent role of bone scanning is evaluating the skeletal areas in patients who have a primary cancer, especially a malignant condition that has a tendency to spread to bone areas. The bone scan is superior to bone radiographs in diagnosing these abnormalities; 15 percent to 25 percent of patients with breast, prostate or lung cancer, who have normal roentgenograms, also have abnormal scintigrams due to metastases. The majority of bone metastases appear as hot spots on the scan and are easily recognized. The incidence of abnormal bone scans in patients with early stages (I and II) of breast cancer varies from 6 percent to 26 percent, but almost invariably those patients with scan abnormalities have a poor prognosis and should be considered for additional therapies. Progression or regression of bony lesions can be defined through scanning, and abnormal areas can be identified for biopsy. The incidence of metastases in solitary scan lesions in patients with known primary tumors varies from 20 percent to 64 percent. Bone scintigraphy shows positive uptake in 95 percent of cases with acute osteomyelitis. Stress fractures and trauma suspected in battered babies can be diagnosed by scanning before there is radiological evidence. The procedure is free from acute or long-term side effects and, except in cases of very young patients, sedation is seldom necessary. Although the test is sensitive, it is not specific and therefore it is difficult to overemphasize the importance of clinical, radiographic, biochemical and scanning correlation in each patient

    Full Text Available A case of squamous cell carcinoma of the tongue with advanced N3 cervical lymph node metastases in an 80-year-old female is reported. The patient was treated with a combination of radiotherapy (2 Gy/day, total 60 Gy, superselective intra-arterial chemotherapy via a superficial temporal artery and a femoral artery (docetaxel, total 124 mg; cisplatin, total 135 mg, and four sessions of hyperthermia for cervical lymph node metastases. The tumor responded well to therapy, and 18-fluorodeoxyglucose uptake in both primary and neck lesions disappeared on positron emission tomography-computed tomography. The patient has shown no clinical or radiological evidence of local recurrence or distant metastases 6 years after the end of treatment. Advanced oral cancer patients with N3 cervical lymph node metastases are particularly difficult to treat and have a poor prognosis. This method of thermochemoradiotherapy seems a promising modality for patients with N3 cervical lymph node metastases of oral cancer.

  3. Radioimmune imaging of bone marrow in patients with suspected bone metastases from primary breast cancer

    International Nuclear Information System (INIS)

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

  4. New Breast Cancer Recursive Partitioning Analysis Prognostic Index in Patients With Newly Diagnosed Brain Metastases

    International Nuclear Information System (INIS)

    Purpose: The aim of the study was to present a new breast cancer recursive partitioning analysis (RPA) prognostic index for patients with newly diagnosed brain metastases as a guide in clinical decision making. Methods and Materials: A prospectively collected group of 441 consecutive patients with breast cancer and brain metastases treated between the years 2003 and 2009 was assessed. Prognostic factors significant for univariate analysis were included into RPA. Results: Three prognostic classes of a new breast cancer RPA prognostic index were selected. The median survival of patients within prognostic Classes I, II, and III was 29, 9, and 2.4 months, respectively (p < 0.0001). Class I included patients with one or two brain metastases, without extracranial disease or with controlled extracranial disease, and with Karnofsky performance status (KPS) of 100. Class III included patients with multiple brain metastases with KPS of ≤60. Class II included all other cases. Conclusions: The breast cancer RPA prognostic index is an easy and valuable tool for use in clinical practice. It can select patients who require aggressive treatment and those in whom whole-brain radiotherapy or symptomatic therapy is the most reasonable option. An individual approach is required for patients from prognostic Class II.

    Brain metastases occur in about 10% to 30% of breast cancer patients, which culminates in a poor prognosis. It is, therefore, critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII-tubulin, Nestin, and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII-tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2, and MDA-MB-468), which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells. PMID:25724666

  11. A case of jawbone necrosis resulting from radiation treatment of multiple bone metastases from breast cancer

    International Nuclear Information System (INIS)

    Radiotherapy for malignant tumors is sometimes associated with side effects that can appear early in the course of treatment. Radiation necrosis of the jawbone sometimes occurs after exposure to a radiation dose of 60 Gy or more for treatment of malignant tumors of the head and neck, and this can have a marked influence on subsequent dental care. The effect is often more marked in the lower than in the upper jaw, and becomes typically evident at the time of tooth extraction. As well as cancers of the head and neck, patients with breast cancer can also be affected by radiation necrosis of the jawbone. It is well known that the rate of bone metastases from breast cancer is much high especially appearing the mandibular in the head and neck lesions. Here we report an overview of jawbone necrosis in the light of our experience of one such case following radiation treatment of multiple bone metastases from breast cancer. (author)

    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.

    International Nuclear Information System (INIS)

    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.

  7. The added diagnostic value of SPECT/CT imaging for bone metastases from lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the added diagnostic value of SPECT/CT imaging over routine planar whole-body bone scintigraphy (WBBS) for bone metastases from lung cancer. Methods: One hundred and forty-six patients with lung cancer, confirmed by pathological examination, underwent routine 99Tcm-MDP (1110 MBq) WBBS, followed by SPECT/CT over the regions with indeterminate findings on WBBS. Both WBBS and bone SPECT/CT images were interpreted by two experienced nuclear medicine physicians in consensus as the positive, negative or uncertain bone metastases. The final diagnosis was com-firmed by pathology or clinical follow-up. χ2 test was used to compare the differences between the two imaging methods. Results: Finally, 45 patients were diagnosed as positive bone metastases and the other 101 as negative. The diagnostic sensitivity of bone SPECT/CT for bone metastases from lung cancer was 93.3% (42/45), significantly higher than that of WBBS (64.4%, 29/45) (χ2=19.944, P<0.05). The diagnostic accuracy of bone SPECT/CT was 89.7% (131/146), much higher than that of WBBS (44.5%, 65/146) (χ2=69.598, P<0.05). The uncertain and incorrect diagnostic rates of bone SPECT/CT and WBBS were 10.3% (15/146, raging from 5.3% to 15.2% with 95% confidence interval (CI)) and 55.5% (81/146, raging from 47.4% to 63.5% with 95% CI), respectively. Conclusion: Bone SPECT/CT provides incremental diagnostic value over routine WBBS for bone metastases from lung cancer. (authors)

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

Methods: We retrospectively analyzed 35 patients with brain metastases from small-cell lung cancer treated with linear accelerator FSRT after the WBRT failure. Multivariate analysis was used to determine significant prognostic factor related to survival. Results: The following-up rate was 100%. The median following-up time was 11 months. The median over-all survival (OS) time was 10.3(1 -30) months after FSRT. Controlled extra cranial disease was the only identified significant predictor of increased median OS time (χ2 =4.02, P =0.045 ). The median OS time from the diagnosis of brain metastasis was 22 (6 - 134 ) months. 14 patients died from brain metastasis, 14 from extra-cranial progression, 1 from leptomeningeal metastases, and 3 from other causes. Local control at 6 months and 12 months was 91% and 76%, respectively. No significant late complications. New brain metastases outside of the treated area developed in 17% of patients at a median time of 4(2 -20) months; all patients had received previous WBRT. Conclusions: Fractionated stereotactic radiotherapy was safe and effective treatment for recurrent small-cell lung carcinoma brain metastases. (authors)

  12. Approaches to chemoradiation therapy of patients with relapses and metastases of brain cancer

    International Nuclear Information System (INIS)

    A possibility and efficacy of chemoradiation therapy (CRT) in patients with relapses and metastases of breast cancer (BC) with the history of radical treatment (combination or chemoradiation therapy with hormone therapy) for local BC is shown. The treatment was differentiated depending of the disease localization. The patients with local relapses in the area of the breast were administered distance radiation therapy (DRT) and 4 courses of polychemotherapy (PCT) by TC protocol (Neotaxel 175 mg/m2 + Carboplatin 250-300 mg/m2). The patients with metastases to the brain were administered Temodal in radiomodifying dose of 75 mg/m2 per day during the course of DRT to the neurocranium, after 4 week break the patients were administered 6 courses of Temozolomide as monotherapy by the standard protocol. The patients with metastases to the skeleton were administered DRT with bisphonoites administration. The described techniques of CRT for relapses and metastases of breast cancer are moderately toxic and demonstrate a favorable profile of safety, which positively influences the quality of life of these patients.

  14. PTEN expression is consistent in colorectal cancer primaries and metastases and associates with patient survival

    International Nuclear Information System (INIS)

    Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) negatively regulates the phosphoinositide-3-kinase (PI3K) signaling pathway. In colorectal cancer (CRC), observed frequencies of loss of PTEN expression, concordant expression in primary tumors and metastases, and the association of PTEN status with outcome vary markedly by detection method. We determined the degree to which PTEN expression is consistent in 70 matched human CRC primaries and liver metastases using a validated immunohistochemistry assay. We found loss of PTEN expression in 12.3% of assessable CRC primaries and 10.3% of assessable liver metastases. PTEN expression (positive or negative) was concordant in 98% of matched colorectal primaries and liver metastases. Next we related PTEN status to mutations in RAS and PI3K pathway genes (KRAS, NRAS, BRAF, and PIK3CA) and to overall survival (OS). PTEN expression was not significantly associated with the presence or absence of mutations in RAS or PI3K pathway genes. The median OS of patients whose tumors did not express PTEN was 9 months, compared to 49 months for patients whose tumors did express PTEN (HR = 6.25, 95% confidence intervals (CI) (1.98, 15.42), P = 0.0017). The association of absent PTEN expression with increased risk of death remained significant in multivariate analysis (HR = 6.31, 95% CI (2.03, 17.93), P = 0.0023). In summary, PTEN expression was consistent in matched CRC primaries and in liver metastases. Therefore, future investigations of PTEN in metastatic CRC can use primary tumor tissue. In patients with liver-only metastases, loss of PTEN expression predicted poor OS. We observed concordant PTEN expression in 98% of colorectal cancer (CRC) primary and liver metastasis pairs using a validated immunohistochemistry assay. Consistent PTEN expression at both disease sites is significant because tumor tissue is usually available from CRC primaries but not metastases. Loss of PTEN expression associated with poor survival of

  16. Impact of Triple-Negative Phenotype on Prognosis of Patients With Breast Cancer Brain Metastases

    International Nuclear Information System (INIS)

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

  17. Results of whole brain radiotherapy in patients with brain metastases from breast cancer: a retrospective study

    International Nuclear Information System (INIS)

    Purpose: To analyze the factors that affect survival in patients with brain metastases (BM) from breast cancer who were treated with whole brain radiotherapy (WBRT). Methods and Materials: We identified 116 women with breast cancer who were treated with WBRT alone between February 1984 and September 2000. All patients had treatment and follow-up data available in their medical charts, which we extracted for this retrospective study. We evaluated a number of potential predictors of survival after WBRT: age, primary tumor stage, control of primary tumor, presence of other systemic metastases, site of systemic metastases, Karnofsky performance status, Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis class, total dose of WBRT, and number of BM. Eighteen patients received a total dose >3000 cGy and 7 received a partial brain boost. Results: For the entire cohort, the median survival from the start of WBRT was 4.2 months. The 1-year survival rate was 17%, and the 2-year survival rate was 2%. Using univariate analysis, only Karnofsky performance status (p=0. 0084), recursive partitioning analysis class (p=0. 0147), and total WBRT dose (p=0.0001) were predictive of longer survival. In multivariate analysis, Karnofsky performance status was the only significant predictor. Conclusion: Overall survival in breast cancer patients with BM treated with WBRT is poor. We recommend breast cancer patients with BM be enrolled in prospective trials to improve results

  19. Clinical efficacy of stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer

    International Nuclear Information System (INIS)

    Limited data describe the prognosis after stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer. Thus, we evaluated treatment outcomes of stereotactic ablative radiotherapy for those patients. The study involved patients received stereotactic ablative radiotherapy for one to three lung metastases arising from colorectal cancer at a single institution. A total dose of 40–60 Gy (median, 48 Gy) in three or four fractions was prescribed. A total of 79 metastatic lung lesions from 50 patients who underwent curative resection for their primary colorectal cancer or salvage treatment at a recurrent site were included. The one- and three-year local control rates were 88.7 % and 70.6 %, respectively. The three-year overall survival and progression-free survival rates were 64.0 % and 24.0 %, respectively. Patients with tumor volume ≤1.5 mL had a significantly better overall survival rate than those with tumor volume >1.5 mL (68.0 % vs. 60.0 % at three-year, p = 0.02). Local control was associated with a trend towards better survival (p = 0.06). No pulmonary complications greater than grade 2 were observed. Stereotactic ablative radiotherapy is a competitive treatment modality for the management of lung metastases arising from colorectal cancer

  1. Treatment results of radioiodine therapy in patients with pulmonary metastases of differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Purpose: Radioiodine treatment is a popular treatment approach for patients with pulmonary metastases of differentiated thyroid cancer. In this study, we evaluated the survival of patients with pulmonary metastases of differentiated thyroid cancer receiving periodic 131I therapy and influence factors of prognosis. Methods: Ninety six patients with pulmonary metastases from well-differentiated thyroid carcinoma received initial 131I therapy in our department from 1976 to December 2001 were reviewed retrospectively. Follow-up data were recorded up to December 2003. Most of them underwent total or near total thyroidectomy before 1311 treatment. Sixty eight patients were PTC and 28 were FC. We had 49 males and 47 females with a mean age of 48.6 years. Thyroid hormone medications were withheld for two weeks for triiodothyronine (T3) and five weeks for thyroxine (T4). For postoperative ablation of thyroid bed remnants, activity in the range of 2.75-5.5 GBq (75-150 mCi) is administered. For treatment of pulmonary metastases, activity of 5.55-7.4 GBq (150-200 mCi) is given every six months. The range of accumulative dose of 131I was 100-1650 mCi. Survival was estimated by using the Kaplan-Meier method. Results: The overall 5-year and 10-year survivals for all patients were 95% and 85%, respectively. The post-lung-metastasis 5-year and 10-year survivals were 81% and 56%, respectively. Twenty-one of 59 (61.5%) of patients had a response after 131I treatment, with a complete response of 24.0% and a partial response of 37.5%, Papillary carcinoma, age less than 45 at diagnosis, treatment response (CR+PR), without other distant metastases, the radioiodine uptake in the lesions are favorite important facts affected prognosis. Conclusions: The results suggest that differentiated thyroid cancer patients with pulmonary metastases are indolent clinical course. 131I is an effective treatment for these patients with pulmonary 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.

    This study compared FDG PET with Tl SPECT in the diagnosis of lymph node metastases from lung cancer. FDG PET and Tl SPECT were performed in the 42 patients with lung cancer. All patients had thoracotomy. FDG PET detected mediastinal lymph node metastasis that was negative on Tl SPECT, whereas both techniques excluded tumor involvement in enlarged node at CT. However, both techniques may show false-negative results for microscopic metastases in normal-sized lymph node. (author)

  4. Gamma knife radiosurgery for metastatic brain tumors. Study of 500 cases with cerebral metastases from major primary cancers

    International Nuclear Information System (INIS)

    The purpose of this retrospective study was to determine the outcome of gamma knife radiosurgery in a variety of patients including relatively poor-risk patients with multiple or large brain metastases. Between April 2000 and March 2007, many patients with cerebral metastases from cancers of the lung, gastrointestinal tract, breast, and kidney were treated with gamma knife radiosurgery at Aizawa Hospital. Of the 500 patients who were suitable for analysis, there were 322 patients with lung cancer, 105 with gastrointestinal cancer, 48 with breast cancer, and 25 with renal cell carcinoma. A total of 728 treatment sessions were required for salvage therapy by June 2008 (the average was 1.5 times in one individual). The median follow-up period was 13.9 months. When the number of metastases was less than 10, the median survival after first gamma knife radiosurgery was 8.5 months in patients with lung cancer, 6 months with gastrointestinal cancer, 13 months with breast cancer, and 11 months with renal cell carcinoma. In a group of 284 patients with non-small cell lung cancer, the median survival was 13 months in patients with one metastasis, 11 months with 2 to 4 metastases, and 5 months with 5 to 10 metastases. There were 66 patients with metastases 3 to 4 cm in diameter, and the median survival was 6 months. There were 10 patients who died from brain metastases (median survival was 16 months), and 8 patients in whom brain-tumor control had failed within 6 months after gamma knife radiosurgery. The results of this study suggest that gamma knife radiosurgery may improve survival in poor-risk patients with multiple or large brain metastases even in palliative management. (author)

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

  7. Diagnosis of bone metastases in prostate cancer patients with SPECT/CT

    International Nuclear Information System (INIS)

    Full text: Introduction: The bone metastases are the first and foremost place for metastases of about 80% of patients with prostate cancer. The diagnosis of bone metastases can be achieved by various imaging methods. They visualize different aspects of the bone tissue according to the bone density, water content, blood flow and metabolism. The bone scintigraphy is a relatively sensitive, inexpensive and low exposure method, which displays the entire skeleton in one session. Materials and Methods: The bone scintigraphy is performed with gamma camera for whole body scanning and SPECT/CT in case of lesions of uncertain nature. 99mTs -MDP (methylene diphosphonate) was used which localizes in bones through physicochemical absorption of phosphorus groups on the calcium of the hydroxyapatite. A pathologically increased focal inclusion was observed in case of overproduction (activation of osteoblasts) with increased mineral metabolism in all pathologies with osteoblastic reactions, such as primary and metastatic tumors, inflammation, fracture, degenerative changes. The absence of bone (osteoclasts activation) is visualized as a cold zone, with or without a hot edge. For multiple metastases the scintigraphic image is typical. In solitary lesions, more careful assessment and use of other imaging methods (SPECT / CT, CT, MRI) is needed in order to differentiate benign from malignant foci. Results: The hybrid image from the SPECT / CT allows precise anatomical localization of pathological foci, which in most of the cases can differentiate benign from malignant lesions. The CT image displays lytic foci, missed by the scintigraphy and improves the scintigraphic image by correction for scattered radiation. The use of low-dose CT reduces radiation exposure more than 40 %. In a retrospective study of 167 newly diagnosed patients with prostate cancer, bone metastases were detected in 20.8%. In asymptomatic patients with Glison score 5 and PSA> 15 and in all patients with T3 - 4 and

  9. Management of germ cell testicular cancer with pulmonary metastases

    International Nuclear Information System (INIS)

    Twenty eight patients with germ cell testicular pulmonary metastases received primary chemotherapy including bleomycin, etoposide, and cisplatin. Complete response (CR) was achieved in 21 (75%) patients, in 11 of them CR was achieved following chemotherapy alone. Post-chemotherapy surgery of residual mass performed in 12 (42.9%) patients with normalized serum tumor markers. Retroperitoneal lymph node dissection was performed in one patient, pulmonary surgery in four, and both post-chemotherapy treatments in 7 patients. Overall cure rate was 89.3%, 26 (92.9%) patients are still alive at a mean follow-up of 19.7+ months (range, 3-34+ months) after the treatment start. Two (7.1%) died: one of them due to disease progression during chemotherapy, and the second one due to postoperative complication (acute respiratory failure). Relapse of disease was observed in one patient 21 months following CR achievement, and sequential chemotherapy was introduced. Authors recommend surgical remove of all radiologically detected residual deposits, because the available imaging methods are not adequate for determining the histologic composition of residual mass, which is decisive for further therapy and has prognostic value.

    As systemic cancer therapies improve and are able to control metastatic disease outside the central nervous system, the brain is increasingly the first site of relapse. The blood–brain barrier (BBB) represents a major challenge to the delivery of therapeutics to the brain. Macrophages originating from circulating monocytes are able to infiltrate brain metastases while the BBB is intact. Here, we show that this ability can be exploited to deliver both diagnostic and therapeutic nanoparticles s...

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

  16. Combined use of zoledronic acid and 153Sm-EDTMP in hormone-refractory prostate cancer patients with bone metastases

    International Nuclear Information System (INIS)

    153Sm-ethylenediaminetetramethylenephosphonic acid (EDTMP; Quadramet registered) is indicated for the treatment of painful bone metastases, whereas zoledronic acid (Zometa registered) is indicated for the prevention of skeletal complications. Because of the different therapeutic effects, combining the treatments may be beneficial. Both, however, accumulate in areas with increased osteoblastic activity. Possible drug interactions were investigated. Patients with hormone-refractory prostate cancer were treated with 18.5 MBq/kg 153Sm-EDTMP in weeks 1 and 3 and with 37 MBq/kg in week 15. Treatment with 4 mg zoledronic acid began in week 3 and continued every 4 weeks through week 23. In weeks 3 and 15, zoledronic acid was administered 2 days before 153Sm-EDTMP treatment. Urine was collected 48 h after injection of 153Sm-EDTMP, and whole-body images were obtained 6, 24 and 48 h post-injection. The effect of zoledronic acid on total bone uptake of 153Sm-EDTMP was measured indirectly by the cumulative activity excreted in the urine in weeks 1, 3 and 15. Biodistribution, safety, tolerability and effect on prostate-specific antigen level were also studied. The urinary excretion in week 3 divided by the urinary excretion in week 1 (baseline) times 100% was mean 98.4 ± 11.6% (median 96.2%). From week 1 to 15, after four zoledronic acid treatments, the mean ratio was 101.9 ± 10.7% (median 101.8%). Bioequivalence could be concluded by using a two-sample t test for both per-protocol (n = 13) and full-analysis sets (n = 18). Toxicity was comparable to of monotherapy with 153Sm-EDTMP.

    Recent genomic studies challenge the conventional model that each metastasis must arise from a single tumor cell and instead reveal that metastases can be composed of multiple genetically distinct clones. These intriguing observations raise the question: How do polyclonal metastases emerge from the primary tumor? In this study, we used multicolor lineage tracing to demonstrate that polyclonal seeding by cell clusters is a frequent mechanism in a common mouse model of breast cancer, accounting for >90% of metastases. We directly observed multicolored tumor cell clusters across major stages of metastasis, including collective invasion, local dissemination, intravascular emboli, circulating tumor cell clusters, and micrometastases. Experimentally aggregating tumor cells into clusters induced a >15-fold increase in colony formation ex vivo and a >100-fold increase in metastasis formation in vivo. Intriguingly, locally disseminated clusters, circulating tumor cell clusters, and lung micrometastases frequently expressed the epithelial cytoskeletal protein, keratin 14 (K14). RNA-seq analysis revealed that K14(+) cells were enriched for desmosome and hemidesmosome adhesion complex genes, and were depleted for MHC class II genes. Depletion of K14 expression abrogated distant metastases and disrupted expression of multiple metastasis effectors, including Tenascin C (Tnc), Jagged1 (Jag1), and Epiregulin (Ereg). Taken together, our findings reveal K14 as a key regulator of metastasis and establish the concept that K14(+) epithelial tumor cell clusters disseminate collectively to colonize distant organs.

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

    Full Text Available Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT/calcium folinate (leucovorin, LV was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

  1. Strontium-89 and pamidronate in combined palliative therapy of osteoblastic-osteolytic breast cancer bone metastases

    International Nuclear Information System (INIS)

    Introduction: The cancer bone metastases in 40% of patients with advanced breast cancer are detected; osteolysis predominates in 70% of cases, but in 30% osteoblastic component is observed, that gives the possibility for use of strontium-89. Aim: The aim of this study was to evaluate the effectiveness of connected therapy using strontium-89 (osteoblastic component) and pamidronate therapy (osteolytic component) in the group of breast cancer patients with multiple osteoblastic-osteolytic (mixed) bone metastases. Material and methods. 13 patients with breast cancer and multiple bone painful metastases (2 or more) detected by scintigraphy and by radiogram or CT or MRI (character of metastases) were included in the study. All patients have been treated with analgetics (NSAID + opioids). Each patient received 150 MBq of strontium-89 (Metastron, Nycomed-Amersham) combined with intravenous infusion of 60 mg pamidronate (Aredia, Novartis) and short low-dose steroid therapy. The bisphosphonate therapy was repeated every month. For assessment of therapy effectiveness, pain relief (VAS scale), a reduction in analgesic requirements and motor activity (ECOG and Karnofsky scale) were evaluated. The group of 10 patients treated with bisphosphonate only in the same time was observed. Results. During follow-up after 4 weeks and 10 weeks of the end of strontium-89 therapy, we noticed pain relief effects as follows: 'good' (VAS5) in 4 patients. We have observed that the analgesic requirements decreased to 30% of dose on average. The motor activity of the points evaluated increased from 3 to 2 in the ECOG scale and from 40 to 60 in the Karnofsky scale. No pathological fractures, hypercalcaemia and other serious side effects with clinical manifestations were observed. The results of treatment in the group with strontium 89 and bisphosphonate were better than in the group treated with bisphosphonates only (40% 'good' and 'moderate' response rate, one case of pathological fracture

    Most breast cancer metastases in bone form osteolytic lesions, but the mechanisms of tumor-induced bone resorption and destruction are not fully understood. Although it is well recognized that Wnt/β-catenin signaling is important for breast cancer tumorigenesis, the role of this pathway in breast cancer bone metastasis is unclear. Dickkopf1 (Dkk1) is a secreted Wnt/β-catenin antagonist. In the present study, we demonstrated that activation of Wnt/β-catenin signaling enhanced Dkk1 expression i...

    The aim of this study was to determine trends in incidence, treatment and survival of colorectal cancer (CRC) patients with synchronous metastases (Stage IV) in the Netherlands. This nationwide population-based study included 160,278 patients diagnosed with CRC between 1996 and 2011. We evaluated changes in stage distribution, location of synchronous metastases and treatment in four consecutive periods, using Chi square tests for trend. Median survival in months was determined, using Kaplan-Meier analysis. The proportion of Stage IV CRC patients (n = 33,421) increased from 19 % (1996-1999) to 23 % (2008-2011, p < 0.001). This was predominantly due to a major increase in the incidence of lung metastases (1.7-5.0 % of all CRC patients). During the study period, the primary tumor was resected less often in Stage IV patients (65-46 %) and the use of systemic treatment has increased (29-60 %). Also an increase in metastasectomy was found in patients with one metastatic site, especially in patients with liver-only disease (5-18 %, p < 0.001). Median survival of all Stage IV CRC patients increased from 7 to 12 months. Especially in patients with metastases confined to the liver or lungs this improvement in survival was apparent (9-16 and 12-24 months respectively, both p < 0.001). In the last two decades, more lung metastases were detected and an increasing proportion of Stage IV CRC patients was treated with systemic therapy and/or metastasectomy. Survival of patients has significantly improved. However, the prognosis of Stage IV patients becomes increasingly diverse. PMID:25899064

  4. Pulmonary fibrosis in youth treated with radioiodine for juvenile thyroid cancer and lung metastases after Chernobyl

    International Nuclear Information System (INIS)

    The objective of this project was to systematically determine the prevalence and consequences of pulmonary fibrosis in youth with thyroid carcinoma and lung metastases from Belarus who were treated with radioiodine (131I). A total of 69 patients treated for juvenile thyroid carcinoma and lung metastasis with 131I were assessed. A group of 29 patients without lung metastases and prior 131I treatment served as controls. The assessments included a CT scan of the lungs, extensive pulmonary function testing and an incremental cycle test to volitional fatigue with measurements of oxygen uptake (V. O2), oxygen saturation and alveolar-arterial difference in oxygen partial pressure (ΔaaO2). Five patients with lung metastases showed advanced pulmonary fibrosis on CT scans and also had poorer lung functions compared with the 62 patients with none or minor signs of fibrosis and the 29 controls. Furthermore, these five patients showed lower peak V.O2, lower oxygen saturation at peak exercise and higher exercise ΔaaO2. They were younger at the time of cancer diagnosis and had received chemotherapy more frequently than youth with pulmonary metastases who did not develop fibrosis. One of the five patients subsequently died from pulmonary fibrosis. Following the Chernobyl catastrophe, about 7% of children treated with radioiodine for thyroid carcinoma and lung metastases displayed pulmonary fibrosis which was associated with functional impairments. Based on the characteristics of affected individuals, the number of radioiodine courses may have to be limited, especially in young children, and chemotherapy should be avoided. (orig.)

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

    Metastatic growth by colorectal cancer cells in the liver requires the ability of the cancer cells to interact with the new microenvironment. This interaction results in three histological growth patterns of liver metastases: desmoplastic, pushing, and replacement. In primary colorectal cancer...... several proteases, involved in the degradation of extracellular matrix components, are up-regulated. In liver metastases, their expression is growth pattern dependent. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a strong prognostic marker in plasma from colorectal cancer patients......, with significant higher levels in patients with metastatic disease. We therefore wanted to determine the expression pattern of TIMP-1 in primary colorectal cancers and their matching liver metastases. TIMP-1 mRNA was primarily seen in α-smooth-muscle actin (α-SMA)-positive cells. In all primary tumors and liver...

  8. Bone metastases in breast cancer and its risk factor

    International Nuclear Information System (INIS)

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

  9. Do patients with very few brain metastases from breast cancer benefit from whole-brain radiotherapy in addition to radiosurgery?

    International Nuclear Information System (INIS)

    An important issue in palliative radiation oncology is the whether whole-brain radiotherapy should be added to radiosurgery when treating a limited number of brain metastases. To optimize personalized treatment of cancer patients with brain metastases, the value of whole-brain radiotherapy should be described separately for each tumor entity. This study investigated the role of whole-brain radiotherapy added to radiosurgery in breast cancer patients. Fifty-eight patients with 1–3 brain metastases from breast cancer were included in this retrospective study. Of these patients, 30 were treated with radiosurgery alone and 28 with radiosurgery plus whole-brain radiotherapy. Both groups were compared for local control of the irradiated metastases, freedom from new brain metastases and survival. Furthermore, eight additional factors were analyzed including dose of radiosurgery, age at radiotherapy, Eastern Cooperative Oncology Group (ECOG) performance score, number of brain metastases, maximum diameter of all brain metastases, site of brain metastases, extra-cranial metastases and the time from breast cancer diagnosis to radiotherapy. The treatment regimen had no significant impact on local control in the univariate analysis (p = 0.59). Age ≤59 years showed a trend towards improved local control on univariate (p = 0.066) and multivariate analysis (p = 0.07). On univariate analysis, radiosurgery plus whole-brain radiotherapy (p = 0.040) and ECOG 0–1 (p = 0.012) showed positive associations with freedom from new brain metastases. Both treatment regimen (p = 0.039) and performance status (p = 0.028) maintained significance on multivariate analysis. ECOG 0–1 was positively correlated with survival on univariate analysis (p < 0.001); age ≤59 years showed a strong trend (p = 0.054). On multivariate analysis, performance status (p < 0.001) and age (p = 0.041) were significant. In breast cancer patients with few brain metastases, radiosurgery plus whole

  10. Prognostic factors for survival of women with unstable spinal bone metastases from breast cancer

    International Nuclear Information System (INIS)

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

  11. Value of diffusion-weighted imaging for diagnosting vertebral metastases due to prostata cancer in comparison to other primary tumors

    International Nuclear Information System (INIS)

    Purpose: Several publications have reported that the apparent diffusion coefficient is generally lower in metastatically affected vertebrae. Therefore, metastases are represented in diffusion-weighted images by increased signal intensity in comparison to unaffected vertebrae. However, there were indications that metastases due to prostate cancer may differ from this. Therefore, the contrast behavior of vertebral metastases due to prostate cancer or tumors with another histology are to be systematically studied using diffusion-weighted images. The present study is intended to examine whether the two groups differed and whether possible differences depended on the degree of sclerosis. Materials and Method: In a retrospective study the vertebral metastases of patients with prostate cancer (n=18) were compared to those of patients with tumors of another histology (n=20). A steady-state free precession sequence was used for the diffusion-weighted imaging. Additionally, a T1 weighted sequence before and after administration of contrast agent as well as a fat suppressed T2 weighted sequence were performed. The contrast behavior of the metastases was evaluated for all four sequences and was compared to that of the unaffected parts of the vertebra. Results: In 18 patients of the tumor group, the vertebral metastases showed positive contrast in the diffusion-weighted images, and 2 had minimally negative contrast up to -0.04. In the prostate cancer group, the contrast was positive in 9 patients and negative in 9.6 of the metastases with negative contrast had an osteoblastic metastasization, 1 had an osteolysis, and 1 had a normal finding in the conventional X-ray image. Between the tumor group and the prostate cancer group, the medians of the contrasts were not significantly different (p=0.054). (orig.)

  12. Whole brain radiotherapy for brain metastases from breast cancer: estimation of survival using two stratification systems

    International Nuclear Information System (INIS)

    Brain metastases (BM) are the most common form of intracranial cancer. The incidence of BM seems to have increased over the past decade. Recursive partitioning analysis (RPA) of data from three Radiation Therapy Oncology Group (RTOG) trials (1200 patients) has allowed three prognostic groups to be identified. More recently a simplified stratification system that uses the evaluation of three main prognostics factors for radiosurgery in BM was developed. To analyze the overall survival rate (OS), prognostic factors affecting outcomes and to estimate the potential improvement in OS for patients with BM from breast cancer, stratified by RPA class and brain metastases score (BS-BM). From January 1996 to December 2004, 174 medical records of patients with diagnosis of BM from breast cancer, who received WBRT were analyzed. The surgery followed by WBRT was used in 15.5% of patients and 84.5% of others patients were submitted at WBRT alone; 108 patients (62.1%) received the fractionation schedule of 30 Gy in 10 fractions. Solitary BM was present in 37.9 % of patients. The prognostic factors evaluated for OS were: age, Karnofsky Performance Status (KPS), number of lesions, localization of lesions, neurosurgery, chemotherapy, absence extracranial disease, RPA class, BS-BM and radiation doses and fractionation. The OS in 1, 2 and 3 years was 33.4 %, 16.7%, and 8.8 %, respectively. The RPA class analysis showed strong relation with OS (p < 0.0001). The median survival time by RPA class in months was: class I 11.7, class II 6.2 and class III 3.0. The significant prognostic factors associated with better OS were: higher KPS (p < 0.0001), neurosurgery (P < 0.0001), single metastases (p = 0.003), BS-BM (p < 0.0001), control primary tumor (p = 0.002) and absence of extracranial metastases (p = 0.001). In multivariate analysis, the factors associated positively with OS were: neurosurgery (p < 0.0001), absence of extracranial metastases (p <0.0001) and RPA class I (p < 0.0001). Our

    The sizes and locations of pulmonary and pleural metastases in chest X-rays of 50 symptomatic and 65 asymptomatic breast cancer patients were compared and correlated to survival. The diameters of the metastases were about the same in both groups as also their distribution. The incidence of pleural fluid was higher in symptomatic patients. The survival curve of symptomatic patients did not deviate from that of the asymptomatic ones. Symptoms in pulmonary metastatic disease do not mean rapid progress of the disease but may be beneficial in that they cause the patient to visit the oncologist early. The cost-effectiveness of chest X-rays in the follow-up is questionable.

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

  15. Treatment of brain metastases from differentiated thyroid cancer with 131I

    International Nuclear Information System (INIS)

    Objective: To study the clinical value of treatment of brain metastases from differentiated thyroid cancer (DTC) with 131I. Methods: Eight cases of brain metastases from DTC were followed-up after 131I therapy (2 males, 6 females). The results of 131I therapy were evaluated with clinical presentation, imaging scan and survival analysis. Results: 1) All cases had been survival for 2-35 years within follow-up. 2)A space-occupying lesion in right cerebellum was shrunk after taking 131I 20.65 GBq and disappeared after 23.61 GBq, demonstrated by CT. 3)The times of treatment and total dose of 131I used for each case were clearly decreased with total thyroidectomy than with semithyroidectomy (P131I may improve clinical symptoms and life quality, reduce lesion size, and prolong survival

  17. Functioning pulmonary metastases of thyroid cancer: does radioiodine influence the prognosis?

    International Nuclear Information System (INIS)

    Functioning pulmonary metastases are the most common distant lesions of differentiated thyroid cancer. About 50% of patients with such metastases die within 10 years. The impact of iodine-131 therapy is controversial. In this study we examined: (1) the early diagnostic value of post-surgery 131I ablation for lung invasion and (2) the survival of patients receiving periodic 131I therapy. Between January 1970 and December 1995 we provided initial treatment for 509 patients with thyroid cancer. Most of them (74%) underwent total thyroidectomy and 131I ablation. Functioning pulmonary metastases occurred in 20 patients. All these patients received periodic 131I therapy for as long as 131I uptake persisted. Additional therapy consisted of lung surgery in three patients and local treatment of bone lesions in four patients. Follow-up data were recorded up to December 2001. Functioning pulmonary metastases occurred late in one patient, and were visible on the post-surgery 131I therapy scan in the other 19 patients. At diagnosis of lung invasion, 11 patients had negative chest X-ray findings, and serum thyroglobulin levels were not suggestive of metastatic disease in 56% of these cases. One of the 11 patients with negative chest X-ray findings died with a neck recurrence, two have persistent pulmonary 131I uptake, and the other eight are in apparent remission after receiving an average cumulative 131I activity of 338 mCi (12.51 GBq). The nine patients with positive chest X-ray findings received an average of 939 mCi (34.74 GBq); two of them died, five are continuing to receive therapy and two are in apparent remission. Overall survival at 10 years is 84%. The average follow-up of the 17 survivors is 12.7 years. These results suggest that patients with functioning pulmonary metastases, even in advanced stages, may survive for many years on 131I therapy. Early diagnosis, during post-surgery 131I scanning, of radiologically inapparent metastases is associated with a better

    International Nuclear Information System (INIS)

    Lytic bone metastases are rare in prostate cancer. We here present 18 fluorine fluorodeoxyglucose (18F-FDG) positron emission tomography computed tomography (PET-CT) images of a 67-year-old male patient with lytic metastases from prostate cancer. Repeat 18F-FDG PET-CT done 6 months later showed response to medical castration therapy. While the role of 18F-FDG PET-CT for sclerotic bone metastases in prostate cancer remains controversial, it appears to be useful for detection and response assessment of lytic prostate cancer metastases.

    A 69-year-old woman was diagnosed with descending colon cancer with multiple liver metastases, and a left hemicolectomy was performed. The patient was treated with capecitabine/oxaliplatin (CapeOX) plus bevacizumab (Bmab). After 5 courses of chemotherapy, the number and size of liver metastases remarkably reduced, and after the 12th course, because of peripheral neuropathy, a "stop-and-go"fashion of administering oxaliplatin (L-OHP) was initiated. After 14 courses, the liver metastases had disappeared. After the 33rd course of L-OHP treatment, the patient started receiving capecitabine therapy. The patient is recurrence-free 3 years after surgery, 14 months after achieving a complete response (CR). We report a case of long-term CR after surgery for descending colon cancer with multiple liver metastases, followed by a "stop-and-go" method of administering L-OHP or CapeOX plus Bmab therapy.

    OBJECT Surgical procedures and/or adjuvant therapies are effective modalities for the treatment of symptomatic spinal metastases. However, clinical results specific to the skin cancer spinal metastasis cohort are generally lacking. The purpose of this study was to systematically review the literature for treatments, clinical outcomes, and survival following the diagnosis of a skin cancer spinal metastasis and evaluate prognostic factors in the context of spinal skin cancer metastases stratified by tumor subtype. METHODS The authors performed a literature review using PubMed, Embase, CINAHL, and Web of Science to identify articles since 1950 that reported survival, clinical outcomes, and/or prognostic factors for the skin cancer patient population with spinal metastases. The methodological quality of reviews was assessed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) tool. RESULTS Sixty-five studies met the preset criteria and were included in the analysis. Of these studies, a total of 25, 40, 25, and 12 studies included patients who underwent some form of surgery, radiotherapy, chemotherapy, or observation alone, respectively. Sixty-three of the 65 included studies were retrospective in nature (Class of Evidence [CoE] IV), and the 2 prospective studies were CoE II. Based on the studies analyzed, the median overall survival for a patient with a spinal metastasis from a primary skin malignancy is 4.0 months; survival by tumor subtype is 12.5 months for patients with basal cell carcinoma (BCC), 4.0 months for those with melanoma, 4.0 months for those with squamous cell carcinoma, 3.0 months for those with pilomatrix carcinoma, and 1.5 months for those with Merkel cell carcinoma (p radiation) alone, or the combination of therapies was similar across interventions. Age, spinal region, and neurological status may be associated with poor survival following surgery. PMID:26544595

  3. Percutaneous cryoablation of liver metastases from breast cancer: Initial experience in 17 patients

    International Nuclear Information System (INIS)

    Aim: To assess the feasibility, safety, and effectiveness of percutaneous cryoablation for the treatment of liver metastases from breast cancer. Materials and methods: This study included 39 liver metastases in 17 female breast cancer patients who underwent computed tomography (CT)-guided percutaneous cryoablation. The mean age of the cohort was 55 years (range 30–66 years). The tumour response was evaluated by CT performed before treatment, 1 month after treatment, and every 3 months thereafter. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) was used to assess the patients' quality of life before, 1 week, 1 month, and 3 months after cryoablation. The primary endpoints were technique effectiveness, quality of life, and complications. Results: The technical success rate was 92% with no major complication reported. At the 1-month follow-up, the primary technique effectiveness was 87.1% (34 of 39 tumours). At the 3-months follow-up, local tumour progression was observed in six of 39 lesions (15.4%). The 1-year survival from the time of cryoablation was 70.6%. The quality of life symptoms and functioning scales were preserved in patients alive at 3 months after cryoablation. The global quality of life, mean value of “pain” and “fatigue” between 3 months after cryoablation and prior to treatment showed statistically significant differences, but no clinical significance. Conclusions: Cryoablation is a safe and effective ablative therapy, providing a high rate of local tumour control in breast cancer liver metastases

    Brain metastases usually present late during the course of breast cancer and are associated with an unfavorable prognosis. It was previously demonstrated that the status of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor type 2 (HER2) may be altered in the time window between the emergence of the primary breast tumor and the development of metastases. The aim of this study was to compare the expression of ER, PR and HER2 in pathology samples of pr...

    Purpose Brain metastases of breast cancer cause neurocognitive damage and are incurable. We evaluated a role for temozolomide in the prevention of brain metastases of breast cancer in experimental brain metastasis models. Experimental Design Temozolomide was administered in mice following earlier injection of brain-tropic human epidermal growth factor receptor 2 (HER2)-positive Jimt1-BR3 and triple negative 231-BR-EGFP sublines, the latter with and without expression of 06-methylguanine-DNA methyltransferase (MGMT). Additionally, the percentage of MGMT-positive tumor cells in 62 patient-matched sets of breast cancer primary tumors and resected brain metastases was determined immunohistochemically. Results Temozolomide, when dosed at 50, 25, 10 or 5 mg/kg, 5 days/week, beginning 3 days after inoculation, completely prevented the formation of experimental brain metastases from MGMT-negative 231-BR-EGFP cells. At a 1 mg/kg dose, temozolomide prevented 68% of large brain metastases, and was ineffective at a dose of 0.5 mg/kg. When the 50 mg/kg dose was administered beginning on days 18 or 24, temozolomide efficacy was reduced or absent. Temozolomide was ineffective at preventing brain metastases in MGMT-transduced 231-BR-EGFP and MGMT-expressing Jimt-1-BR3 sublines. In 62 patient-matched sets of primary breast tumors and resected brain metastases, 43.5% of the specimens had concordant low MGMT expression, while in another 14.5% of sets high MGMT staining in the primary tumor corresponded with low staining in the brain metastasis. Conclusions Temozolomide profoundly prevented the outgrowth of experimental brain metastases of breast cancer in an MGMT-dependent manner. These data provide compelling rationale for investigating the preventive efficacy of temozolomide in a clinical setting. PMID:24634373

  11. Methylation signature of lymph node metastases in breast cancer patients

    International Nuclear Information System (INIS)

    Invasion and metastasis are two important hallmarks of malignant tumors caused by complex genetic and epigenetic alterations. The present study investigated the contribution of aberrant methylation profiles of cancer related genes, APC, BIN1, BMP6, BRCA1, CST6, ESR-b, GSTP1, P14 (ARF), P16 (CDKN2A), P21 (CDKN1A), PTEN, and TIMP3, in the matched axillary lymph node metastasis in comparison to the primary tumor tissue and the adjacent normal tissue from the same breast cancer patients to identify the potential of candidate genes methylation as metastatic markers. The quantitative methylation analysis was performed using the SEQUENOM’s EpiTYPER™ assay which relies on matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The quantitative DNA methylation analysis of the candidate genes showed higher methylation proportion in the primary tumor tissue than that of the matched normal tissue and the differences were significant for the APC, BIN1, BMP6, BRCA1, CST6, ESR-b, P16, PTEN and TIMP3 promoter regions (P<0.05). Among those candidate methylated genes, APC, BMP6, BRCA1 and P16 displayed higher methylation proportion in the matched lymph node metastasis than that found in the normal tissue (P<0.05). The pathway analysis revealed that BMP6, BRCA1 and P16 have a role in prevention of neoplasm metastasis. The results of the present study showed methylation heterogeneity between primary tumors and metastatic lesion. The contribution of aberrant methylation alterations of BMP6, BRCA1 and P16 genes in lymph node metastasis might provide a further clue to establish useful biomarkers for screening metastasis

  12. Macrophage inhibitory cytokine-1 (MIC-1/GDF15 slows cancer development but increases metastases in TRAMP prostate cancer prone mice.

    Yasmin Husaini

    Full Text Available Macrophage inhibitory cytokine-1 (MIC-1/GDF15, a divergent member of the TGF-β superfamily, is over-expressed by many common cancers including those of the prostate (PCa and its expression is linked to cancer outcome. We have evaluated the effect of MIC-1/GDF15 overexpression on PCa development and spread in the TRAMP transgenic model of spontaneous prostate cancer. TRAMP mice were crossed with MIC-1/GDF15 overexpressing mice (MIC-1(fms to produce syngeneic TRAMP(fmsmic-1 mice. Survival rate, prostate tumor size, histopathological grades and extent of distant organ metastases were compared. Metastasis of TC1-T5, an androgen independent TRAMP cell line that lacks MIC-1/GDF15 expression, was compared by injecting intravenously into MIC-1(fms and syngeneic C57BL/6 mice. Whilst TRAMP(fmsmic-1 survived on average 7.4 weeks longer, had significantly smaller genitourinary (GU tumors and lower PCa histopathological grades than TRAMP mice, more of these mice developed distant organ metastases. Additionally, a higher number of TC1-T5 lung tumor colonies were observed in MIC-1(fms mice than syngeneic WT C57BL/6 mice. Our studies strongly suggest that MIC-1/GDF15 has complex actions on tumor behavior: it limits local tumor growth but may with advancing disease, promote metastases. As MIC-1/GDF15 is induced by all cancer treatments and metastasis is the major cause of cancer treatment failure and cancer deaths, these results, if applicable to humans, may have a direct impact on patient care.

  13. Diagnosis of metastases in the skeletal system of carcinomas of the prostate by means of camera scintigraphy

    International Nuclear Information System (INIS)

    The findings of the present study indicate that camera scintiscanning is of major importance in the diagnosis of carcinomas of the prostate. With a diagnostic sensitivity of 100%, camera scintiscanning with the aid of sup(99m)Tc phosphate compounds is the most sensitive method of detecting bone metastases, although the X-ray picture, necessary in case of positive findings, cannot be dispensed with. In carcinomas of the prostate, skeleton scintisanning is very valuable as basic examination and for course control. In patients without primary bone metastases, control scintiscans at regular intervals and especially comparisons of scintiscans are the fastest and safest way of detecting new foci in the skeleton. In existing metastases, the accumulation intensity - which is a function of the extent to which the bone metabolism is enhanced - enables the physician to control the effectivity of a tumour therapy by means of scintiscanning and thus to gain an objective picture of the onset, the amount or the lack of a therapeutic effect.

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.

    2009-12-01

    Full Text Available Background and objective Brain metastases are common in non-small-cell lung cancer (NSCLC and the prognosis is poor. Erlotinib is a specific inhibitor of the epidermal growth factor receptor-associated tyrosine kinase (EGFRTKI, which has been gradually used in the treatment for advanced NSCLC. The aim of this study is to evaluate the antitumor efficacy and its relevant factors of erlotinib in NSCLC patients with brain metastases. Methods The clinical data of 30 NSCLC patients with brain metastases were reviewed retrospectively. All of them were treated with erlotinib, given orally 150mg daily. These patients discontinued administration of erlotinib until disease progression, death or intolerable side effects. Results In terms of intracranial lesions, partial response (PR was observed in 2 patients (6.7%, with stable disease (SD in 17 patients (56.7%, for overall disease control rate (DCR of 63.4%. As for systemic disease, PR was observed in 2 patients (6.7%, with SD in 5 patients (16.7%, for overall DCR of 23.4%. There was no statistical difference in DCR among different subtypes of age, gender, smoking history, histology, PS score, the number of brain metastases, the onset of brain metastases, chemotherapy, brain radiotherapy and side effects. The median time to disease progression (MTTP and median survival time (MST was 2.4 months and 7.7 months respectively. The 1 and 2 year survival rate was 38.4% and 15.2%. The univariate analysis showed that the survival time was related to the patients’ PS score, smoking history, brain radiotherapy and chemotherapy. The multivariate analysis indicated that brain radiotherapy was the independent prognostic factor and the relationship between the survival time and smoking history was near to statistical significance. Conclusion The patients receiving brain radiotherapy may have better survival benefit. Non-smokers have a trend to survive longer than smokers. Erlotinib may be effective on brain metastases

  18. Role of radiotherapy for the esophageal cancer with distant organ metastases

    International Nuclear Information System (INIS)

    Eighty-nine patients with esophageal cancer that had metastases of distant organs were categorized into three groups on the basis of prognosis. Median survival time of the poor-prognosis group (performance status ≥2 and metastases not confined to the thoracic cavity) was 2 months. Because the median time to treatment effect by radiotherapy in this group was 4 weeks, the selection of a modality that can achieve more rapid improvement is recommended. Median survival time of the good-prognosis group (performance status =0-1 and metastases confined to the thoracic cavity) was 7.5 months. Because the contribution of local control to survival was greatest in this group, combined-modality treatment with radiotherapy is recommended. Among patients who could not eat solid food, swallowing function was improved temporarily by radiotherapy in more than 60%. However, this improvement did not result in long-term normal or near-normal swallowing function. In patients who could eat solid food, radiotherapy was effective for maintaining normal swallowing function. (author)

Materials and methods: The study was retrospectively performed. 56 patients (mean age, 52.4) with unresectable liver metastases of gastric cancer who did not respond to systemic chemotherapy were repeatedly treated with TACE in 4-week intervals. In total, 310 chemoembolization procedures were performed (mean, 5.5 sessions per patient). The local chemotherapy protocol consisted of mitomycin alone (30.4%), mitomycin and gemcitabine (33.9%), or mitomycin, gemcitabine and cisplatin (35.7%). Embolization was performed with lipiodol and starch microspheres. Local tumor response was evaluated by MRI according to RECIST. Survival data from first chemoembolization were calculated according to the Kaplan–Meier method. Results: The local tumor control was: complete response in 1.8% (n = 1), partial response in 1.8% (n = 1), stable disease in 51.8% (n = 29) and progressive disease in 44.6% (n = 25) of patients. The 1-, 2-, and 3-year survival rate from the start of chemoembolization were 58%, 38%, and 23% respectively. The median and mean survival times were 13 and 27.1 months. A Statistically significant difference between patients treated with different chemotherapy protocols was noted (ρ = 0.045) with the best survival time in the mitomycin, gemcitabine and cisplatin group. Conclusion: Transarterial chemoembolization is a minimally invasive therapy option for palliative treatment of liver metastases in patients with gastric cancer.

    The purpose of this study was to evaluate the efficacy of transarterial chemoembolization (TACE) using different drug combinations in the treatment of breast cancer liver metastases in terms of local tumor control and survival rate. A total of 208 patients (mean age 56.4 years, range 29-81) with unresectable hepatic metastases of breast cancer were repeatedly treated with TACE at 4-week intervals. In total, 1,068 chemoembolizations were performed (mean 5.1 sessions/patient, range 3-25). The chemotherapy protocol consisted of mitomycin-C only (8 mg/m{sup 2}; n=76), mitomycin-C with gemcitabine (n=111), and gemcitabine only (1,000 mg/m{sup 2}; n=21). Embolization was performed with lipiodol and starch microspheres. Tumor response was evaluated by MRI according to RECIST criteria. Survival rates were calculated using Kaplan-Meier method. For all protocols, local tumor control was partial response 13% (27/208), stable disease 50.5% (105/208), and progressive disease 36.5% (76/208). The 1-, 2-, and 3-year survival rates after TACE were 69, 40, and 33%. Median and mean survival times from the start of TACE were 18.5 and 30.7 months. Treatment with mitomycin-C only showed median and mean survival times of 13.3 and 24 months, with gemcitabine only they were 11 and 22.3 months, and with a combination of mitomycin-C and gemcitabine 24.8 and 35.5 months. TACE is an optional therapy for treatment of liver metastases in breast cancer patients with better results from the combined chemotherapy protocol. (orig.)

    International Nuclear Information System (INIS)

    Objective: This study was to evaluate the efficacy of Samarium-153-EDTMP in breast cancer with bone metastases. Methods: 438 cases with advanced breast cancer that had metastatic bone pain were treated with 153Sm-EDTMP at a dosage of 25.9 MBq/Kg once a month. One course of treatment was 3 to 4 times. Results: The results were evaluated according to the degree of pain relief, mobility, analgesic intake and general feeling. 52.7% (231/438) of patients got complete remission and 33.8% (148/438) incomplete remission. There was no response in the remaining 13.8% (59/438). 52 cases had improved bone scan findings. Conclusion: Palliative treatment of metastatic bone pain from breast cancer with 153Sm-EDTMP improves the quality of life and may be safely repeated with the same benefit and without significant myelosuppression

    Background KRAS mutations in colorectal cancer primary tumors predict resistance to anti-Epidermal Growth Factor Receptor (EGFR) monoclonal antibody therapy in patients with metastatic colorectal cancer, and thus represent a true indicator of EGFR pathway activation status. Methodology/Principal Findings KRAS mutations were retrospectively studied using polymerase chain reactions and subsequent sequencing of codons 12 and 13 (exon 2) in 110 patients with metastatic colorectal tumors. These studies were performed using tissue samples from both the primary tumor and their related metastases (93 liver, 84%; 17 lung, 16%). All patients received adjuvant 5-Fluorouracil-based polychemotherapy after resection of metastases. None received anti-EGFR therapy. Mutations in KRAS were observed in 37 (34%) of primary tumors and in 40 (36%) of related metastases, yielding a 94% level of concordance (kappa index 0.86). Patients with primary tumors possessing KRAS mutations had a shorter disease-free survival period after metastasis resection (12.0 vs 18.0 months; P = 0.035) than those who did not. A higher percentage of KRAS mutations was detected in primary tumors of patiens with lung metastases than in patients with liver metastases (59% vs 32%; p = 0.054). To further evaluate this finding we analyzed 120 additional patients with unresectable metastatic colorectal cancer who previously had their primary tumors evaluated for KRAS mutational status for clinical purposes. Separately, the analysis of these 120 patients showed a tendency towards a higher degree of KRAS mutations in primary tumors of patients with lung metastases, although it did not reach statistical significance. Taken together the group of 230 patients showed that KRAS was mutated significantly more often in the primary tumors of patients with lung metastases (57% vs 35%; P = 0.006). Conclusions/Significance Our results suggest a role for KRAS mutations in the propensity of primary colorectal tumors to

  4. Axillary lymph node metastases in breast cancer: preoperative detection with dynamic contrast-enhanced MRI

    International Nuclear Information System (INIS)

    Metastatic involvement of axillary lymph nodes is one of the most important prognostic variables in breast cancer. The aim of our work was to study the value of dynamic contrast-enhanced MR imaging in revealing axillary lymph node metastases from breast cancer. A total of 65 patients with invasive breast cancer treated with axillary lymph node dissection were preoperatively evaluated by MRI. T1-weighted dynamic contrast-enhanced 3D images were acquired using a coil covering the breast and the axilla. The dynamic contrast enhancement, size, and morphology of the axillary lymph nodes were registered. Histopathological examination revealed axillary lymph node metastases in 24 patients. When using a signal intensity increase in the lymph nodes of > 100 % during the first postcontrast image as a threshold for malignancy, 57 of 65 patients were correctly classified (sensitivity 83 %, specificity 90 %, accuracy 88 %). These results were not improved when lymph node size and morphology were used as additional criteria. Axillary lymph nodes can be evaluated as a part of an MR-mammography study without substantial increase in examination time, and provide the surgeon with knowledge about the localization of possible metastatic lymph nodes.

    Full Text Available The data of 60 patients with metastatic kidney cancer involving the vertebrae who had undergone different-volume surgery were retrospectively analyzed. The role of surgical volume was assessed. In patients with solitary spinal metastases, their radical removal was found to lead to better quality of life and longer survival. Puncture vertebroplasty with bone cement in patients with spinal metastatic involvement permits one to avoid traumatic fixing operations, without reducing the median survival at the same time.

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

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

    Objective: To evaluate the association between p53 codon 72 polymorphism (R72P) and the risk of colorectal liver metastases. Methods: The p53 R72P genotype was identified by polymerase chain reaction-restriction fi'agment length poly-morphism (PCR-RFLP) method in 78 consecutive colorectal cancer patients with liver metastases and 214 age- and sex-matched cases with nonmetastatic colorectai cancer. Results: The R allele of the p53 R72P polymorphism was more frequently found in metastatic cases than in nonmetastatic cases (P=0.075). Carriers of the 72R allele had a 2.25-fold (95% CI (confidence inter-val)=1.05~4.83) increased risk of liver metastases. On the stratification analysis, 72R-carrying genotype conferred a 3.46-fold (95% CI=1.02~11.72) and a 1.05-fold (95% CI=0.36~3.08) increased risk of liver metastases for p53 overexpression-positive and negative colorectal cancers, respectively. Conclusion: These results demonstrate for the first time that the 72R allele of the p53 polymorphism has an increased risk for liver metastases in colorectal cancers positive for p53 overexpression.

    Up to 40% non-small cell lung cancer patients developed brain metastasis during progression. Multiple brain metastases are common in non-small cell lung cancer. The prognosis of brain metastasis is poor with median survival of less than 1 year. Radio therapy for brain metastases has gradually developed from whole brain radiotherapy (WBRT) to various radiation strategies. WBRT, surgery+WBRT, stereotactic radiotherapy+WBRT or WBRT with simultaneous integrated boost (SIB), etc. have better overall survival than those untreated patients. The damage of the cognitive function from WBRT has been realized recently, however, options of radiation strategies for long expected survival patients remain controversial. This paper will discuss different WBRT strategies and treatment side effects of non-small cell lung cancer with brain metastases. PMID:27118651

  11. The relationship between initial 131I uptake by lung metastases from differentiated thyroid cancer and treatment outcomes

    International Nuclear Information System (INIS)

    Objective: To investigate the potential relationship between initial 131I uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods: From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131I whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The χ2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131I treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% (15/41) patients, 131I treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131I lung uptake had higher effective rate than those with 131I lung uptake during the second or later 131I treatment (76% (22/29) vs 33% (4/12), χ2=4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), χ2=6.312, P=0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% (14/23), χ2=0.146, P=0.702). The positive rate of initial 131I uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12)). Those positive rates in patients with papillary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131I uptake by lung metastases (r= 0.411, P<0.05), but no correlation was found between the histological type and the initial 131I uptake by lung metastases (r=0.047, P>0.05). Conclusion: Initial uptake of 131I by lung metastases alone is a favorable prognostic factor for DTC

    Objective: Evaluation of the efficacy and tolerability of transarterial chemoembolization with gemcitabine in patients with inoperable liver metastases of breast cancer. Materials and methods: Open-label, prospective non-randomized single-center study design; patients had previous chemotherapy including anthracyclines and/or taxanes in the metastatic setting, adequate bone marrow reserve, sufficient liver/renal function, no centralnervous system metastases, Karnovsky-performance-status >70%, and life expectancy >12 weeks. Forty-three patients were enrolled (median 58 years, range 48–71). A suspension of gemcitabine 1.200 mg/m{sup 2}, 2–10 ml/m{sup 2} of Lipiodol, and 5 ml of a degradable starch microsphere (Embocept) suspension, were administered intra-arterially up to 3 times with a 4-weaks-interval. Dose-limiting toxicit is defined as grade 4 thrombocytopenia, neutropenia, or nonhematologic toxicity > grade 3. Tumor response was evaluated by magnetic resonance (MRI) and computed tomography (CT) imaging. Results: All patients tolerated the treatment well; with no dose limiting toxicities. Imaging follow-up according to the RECIST-criteria (Response Evaluation Criteria in Solid Tumors) revealed a partial response in 3 patients, stable disease in 16 patients and progression in 22 patients. The progression free survival was 3.3 months. A significant correlation exists only with the factor vascularization: strongly vascularized tumors show a significantly lowered response. Patients with complete or partial response and the main fraction of the stable disease group showed in the MRI and angiography only a moderate vascularization. The resulting estimate of the total survival rate amounts to a median of 10.2 months. Conclusion: Transarterial chemoembolization with gemcitabine is well tolerated and provides an alternative treatment method for patients with liver metastases of breast cancer.

    Abstract The mutational profiles of primary colorectal cancers (CRCs) and corresponding ovarian metastases were compared. Using a custom‐made next generation sequencing panel, 115 cancer‐driving genes were analyzed in a cohort of 26 primary CRCs and 30 matching ovarian metastases (four with bilateral metastases). To obtain a complete overview of the mutational profile, low thresholds were used in bioinformatics analysis to prevent low frequency passenger mutations from being filtered out. A subset of variants was validated using Sanger and/or hydrolysis probe assays. The mutational landscape of CRC that metastasized to the ovary was not strikingly different from CRC in consecutive series. When comparing primary CRCs and their matching ovarian metastases, there was considerable overlap in the mutations of early affected genes. A subset of mutations demonstrated less overlap, presumably being passenger mutations. In particular, primary CRCs showed a substantially high number of passenger mutations. We also compared the primary CRCs and matching metastases for stratifying variants of six genes (KRAS, NRAS, BRAF, FBXW7, PTEN and PIK3CA) that select for established (EGFR directed) or future targeted therapies. In a total of 31 variants 12 were not found in either of the two locations. Tumours thus differed in the number of discordant variants between the primary tumours and matching metastases. Half of these discordant variants were definitive class 4/5 pathogenic variants. However, in terms of temporal heterogeneity, no clear relationship was observed between the number of discordant variants and the time interval between primary CRCs and the detection of ovarian metastases. This suggests that dormant metastases may be present from the early days of the primary tumours. PMID:27499925

    Background The prognosis for patients with gastric cancer and synchronous liver metastases is very poor.However,a standard therapeutic strategy has not been well established.The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.Methods Records of 105 patients who underwent gastrectomy regardless of hepatic surgical treatment for gastric cancer with synchronous liver-only metastases in our center between 1995 and 2010 were retrospectively reviewed.Results The overall survival rate for the 105 patients was 42.1%,17.2%,and 10.6% at 1,2,and 3 years,respectively,with a median survival time of 11 months.Multivariate survival analysis revealed that the extent of lymphadenectomy (D) (P <0.001),lymph node metastases (P <0.001),extent of liver metastases (H) (P=0.008),and lymphovascular invasion (P=-0.002) were significant independent prognostic factors for survival.Among patients who underwent D2 lymphadenectomy,those who underwent hepatic surgical treatment had a significantly improved survival compared with those who underwent gastrectomy alone (median survival,24 vs.12 months; P <0.001).However,hepatic surgical treatment was not a prognostic factor for patients who underwent D1 lymphadenectomy (median survival,8 vs.8 months;P=0.495).For the 35 patients who underwent gastrectomy plus hepatic surgical treatment,D2 lymphadenectomy (P <0.001),lymph node metastases (P=-0.015),and extent of liver metastases (H1 vs.H2 and H3) (P=-0.017) were independent significant prognostic factors for survival.Conclusions D2 lymphadenectomy plus hepatic surgical treatment may provide hope for long-term survival of judiciously selected patients with hepatic metastases from gastric cancer.Patients with a low degree of lymph node metastases and H1 liver metastases would make the most appropriate candidates.However,if D2 dissection cannot be achieved,hepatic surgical treatment is not recommended.

  18. In vivo imaging of pancreatic tumours and liver metastases using 7 Tesla MRI in a murine orthotopic pancreatic cancer model and a liver metastases model

    International Nuclear Information System (INIS)

    Pancreatic cancer is the fourth leading cause of tumour death in the western world. However, appropriate tumour models are scarce. Here we present a syngeneic murine pancreatic cancer model using 7 Tesla MRI and evaluate its clinical relevance and applicability. 6606PDA murine pancreatic cancer cells were orthotopically injected into the pancreatic head. Liver metastases were induced through splenic injection. Animals were analyzed by MRI three and five weeks following injection. Tumours were detected using T2-weighted high resolution sequences. Tumour volumes were determined by callipers and MRI. Liver metastases were analyzed using gadolinium-EOB-DTPA and T1-weighted 3D-Flash sequences. Tumour blood flow was measured using low molecular gadobutrol and high molecular gadolinium-DTPA. MRI handling and applicability was similar to human systems, resolution as low as 0.1 mm. After 5 weeks tumour volumes differed significantly (p < 0.01) when comparing calliper measurments (n = 5, mean 1065 mm3+/-243 mm3) with MRI (mean 918 mm3+/-193 mm3) with MRI being more precise. Histology (n = 5) confirmed MRI tumour measurements (mean size MRI 38.5 mm2+/-22.8 mm2 versus 32.6 mm2+/-22.6 mm2 (histology), p < 0,0004) with differences due to fixation and processing of specimens. After splenic injection all mice developed liver metastases with a mean of 8 metastases and a mean volume of 173.8 mm3+/-56.7 mm3 after 5 weeks. Lymphnodes were also easily identified. Tumour accumulation of gadobutrol was significantly (p < 0.05) higher than gadolinium-DTPA. All imaging experiments could be done repeatedly to comply with the 3R-principle thus reducing the number of experimental animals.

    Full Text Available Trastuzumab treatment does not prevent intracranial seeding and is largely ineffective for established central nervous system metastasis in HER2 overexpressing breast cancer patients. Combination therapy of lapatinib and capecitabine may be an effective treatment option for brain metastasis of HER2-positive breast cancer. We report a patient with breast cancer overexpressing HER-2 where brain metastases were successfully treated with radiation and a combination of lapatinib and capecitabine.

    Recent studies conducted in patients with chronic diseases have reported an inverse association between body mass index (BMI) and mortality. However, the question as to whether BMI may predict prognosis in patients with metastatic cancer remains open. We therefore designed the current retrospective study to investigate the potential association between BMI and overall survival (OS) in patients with distant metastases (DM) and a favorable performance status. Between 2000 and 2012, a total of 4010 cancer patients with DM who required radiotherapy (RT) and had their BMI measured at the initiation of RT were identified. The relation between BMI and OS was examined by univariate and multivariable analysis. The median OS time was 3.23 months (range: 0.1-122.17) for underweight patients, 6.08 months (range: 0.03-149.46) for normal-weight patients, 7.99 months (range: 0.07-158.01) for overweight patients, and 12.49 months (range, 0.2-164.1) for obese patients (log-rank: P HR = 0.676; 95% P HR = 0.84; P HR = 1.41; P performance status. Increased BMI may play a role to identify metastatic patients with superior survival outcome and exhibit a potential to encourage aggressive management in those patients even with metastases.

    2010-05-01

    Breast cancer continues to be one of the leading causes of cancer death in women. Mortality is primarily due to the development of metastases. Although therapies exist, they lack efficacy in preventing metastatic growth. As a result, novel agents are being investigated. In particular, treatments that target the immune system are being examined as potential anti-neoplastic agents. Cordyceps sinensis (Cs) is a fungus that has been used for over 2,000 years in China as a treatment for a variety of conditions including neoplasms. The available evidence suggests that efficacy of Cs as an anti-neoplastic therapeutic agent is related to a role as an activator of innate immune responses. The objectives of this study were: to investigate the ability of Cs to activate macrophages to produce factors that will induce protective responses against tumour growth; to study the ability of Cs to reduce primary tumour growth in vivo; and to examine the ability of Cs to reduce lung metastasis growth in vivo. We found that oral Cs does not reduce primary tumour growth but can reduce lung metastasis occurrence in a surgical excision model of metastatic mammary carcinoma. The evidence we have shown to date suggests that the reduction in metastases growth may be due to the effects of macrophage-derived factors on tumour cell cycle. PMID:19956948

  3. EORTC QLQ-BM22 and QLQ-C30 quality of life scores in patients with painful bone metastases of prostate cancer treated with strontium-89 radionuclide therapy

    International Nuclear Information System (INIS)

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

  4. Palliative effect of Re-186 HEDP in different cancer patients with bone metastases

    International Nuclear Information System (INIS)

    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 3rd and the 7th 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

    We treated 17 patients with metastatic pulmonary and pleural breast cancer by a combination of radiation, chemotherapy and hyperthermia. Hyperthermia with chemotherapy using adriamycin, farmorubicin, mitomycin C, 5-fluorouracil, tegafur and/or cisplatin in the form of continuous intravenous infusion was given. The thermochemotherapy had only a limited effectiveness. But good responses are seen in postirradiation adjuvant thermochemotherapy. Heating could alleviate some chemotherapeutic side effects in some way by heat reservoir. Fifty percent survival period was 12 months by the Kaplan-Meier method. As severe or serious side effects were not experienced, this treatment was thought available for outpatients. We believe that multimodality treatment by thermochemotherapy with radiation is promising for advanced or recurrent pulmonary metastases of breast cancers. (author).

  6. Can bone metastases from mammary carcinomas and their regional distribution patterns established on the basis of radionuclide studies provide any clues to the mechanisms of their further spread over the skeletal system

    International Nuclear Information System (INIS)

    Retrospective analysis of data from 100 female patients showing metastisation from mammary carcinomas into the bones led to the conclusion that the vertrebral column must be a factor in the spread of those metastases to more remote skeletal regions. This is primarily explained by the role of the vertebral venous system and the special action of the red bone marrow that enhances the establishment of cells capable of metastisation. (TRV)

  7. 177Lu-EDTMP for palliation of pain from bone metastases in patients with prostate and breast cancer: a phase II study

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the efficacy and safety of 177Lu-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 177Lu-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 177Lu-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 177Lu-EDTMP was found to be a safe and effective radiopharmaceutical for bone pain palliation in patients with metastatic prostate and breast carcinoma. There were no differences in efficacy or toxicity between patients receiving low-dose and high-dose 177Lu-EDTMP. (orig.)

  8. Multi-factor analysis on events related to hematological toxicity in 153Sm-EDTMP palliative therapy for skeletal metastases

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical factors related to hematological toxicity induced by intravenous samarium-153 ethylenediaminetetramethylene phosphonic acid (153Sm-EDTMP) treatment. Methods A total of 206 patients with bony metastases treated with 153Sm-EDTMP were retrospectively analyzed. Logistic regression (SPSS 10.0 for Windows) and correlation analysis were used to evaluate the factors concerned. Results: Age of the patient, number of bone metastatic lesion, chemotherapy before 153Sm-EDTMP therapy, concurrent radiotherapy and repeat-times of 153Sm-EDTMP treatments were found the individual factors related to hematological toxicity. Chemotherapy before 153Sm-EDTMP, concurrent radiotherapy, medication for normal blood counting and repeat-times of 153Sm-EDTMP treatments were the hematological toxicity factors in multi-factor analysis. Conclusion: In 153Sm-EDTMP therapy, several factors were found related to hematological toxicity suggesting more attention be paid to the change of blood cell counting after the palliative therapy.

    Liver metastases in breast cancer are associated with a poor prognosis. We report long-term survival of a patient with breast cancer and liver metastases. After operation the patient declined further standard therapy. Instead, she was treated with local hyperthermia, Newcastle disease virus and dendritic cell vaccination at the Immunological and Oncological Center Cologne (IOZK), Germany. A continuous high quality of life was reported and the patient survived more than 66 months after initial diagnosis. No recurrence or further metastases developed under treatment. Following treatment, a long-lasting tumor-reactive memory T-cell responsiveness could be documented. This possibly explains the favorable course of disease. Since this combination of therapies is not restricted to a particular tumor type, further exploration is warranted. PMID:26020523

  10. EGFR and HER2 expression in primary cervical cancers and corresponding lymph node metastases: Implications for targeted radiotherapy

    International Nuclear Information System (INIS)

    Proteins overexpressed on the surface of tumor cells can be selectively targeted. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are among the most often targeted proteins. The level and stability of expression in both primary tumors and corresponding metastases is crucial in the assessment of a receptor as target for imaging in nuclear medicine and for various forms of therapy. So far, the expression of EGFR and HER2 has only been determined in primary cervical cancers, and we have not found published data regarding the receptor status in corresponding metastatic lesions. The goal of this study was to evaluate whether any of these receptors are suitable as target for clinical diagnosis and therapy. Expression of EGFR and HER2 was investigated immunohistochemically in both lymph node metastases and corresponding primary cervical cancers (n = 53). HER2 and EGFR expression was scored using HercepTest criteria (0, 1+, 2+ or 3+). EGFR overexpression (2+ or 3+) was found in 64% (35/53) of the primary cervical tumors and 60% (32/53) of the corresponding lymph node metastases. There was a good concordance between the primary tumors and the paired metastases regarding EGFR expression. Only four patients who had 2+ or 3+ in the primary tumors changed to 0 or 1+ in lymph node metastases, and another two cases changed the other way around. None of the primary tumors or the lymph node metastases expressed HER2 protein. The EGFR expression seems to be common and stable during cervical cancer metastasis, which is encouraging for testing of EGFR targeted radiotherapy. HER2 appears to be of poor interest as a potential target in the treatment of cervical cancer

    Full Text Available Purpose: Metastasis to adrenal gland from lung, breast, and kidney malignancies are quite common. Historically radiotherapy was intended for pain palliation. Recent studies with stereotactic body radiotherapy (SBRT including Cyberknife robotic radiosurgery aiming at disease control brings about encouraging results. Here we represent the early clinical experience with Cyberknife stereotactic system from an Indian cancer care center. The main purpose of this retrospective review is to serve as a stepping stone for future prospective studies with non- invasive yet effective technique compared to surgery. Methods: We retrospectively reviewed four cases of adrenal metastases (three: lung and one: renal cell carcinoma treated with Cyberknife SBRT. X sight spine tracking was employed for planning and treatment delivery. Patients were evaluated for local response clinically as well as with PETCT based response criteria.Results: With a median gross tumor volume of 20.5 cc and median dose per fraction of 10 Gy, two patients had complete response (CR and two had partial response (PR when assessed 8-12 weeks post treatment as per RECIST. There was no RTOG grade 2 or more acute adverse events and organs at risk dosage were acceptable. Till last follow up all the patients were locally controlled and alive. Conclusion: Cyberknife SBRT with its unique advantages like non- invasive, short duration outpatient treatment technique culminating in similar local control rates in comparison to surgery is an attractive option. World literature of linear accelerator based SBRT and our data with Cyberknife SBRT with small sample size and early follow up are similar in terms of local control in adrenal metastases. Future prospective data would reveal more information on the management of adrenal metastases.

  12. Gamma Knife Radiosurgery for Treatment of Cerebral Metastases From Non–Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To evaluate clinical and physico-dosimetric variables affecting clinical outcome of patients treated with Gamma Knife radiosurgery (GKRS) for brain metastases from non–small cell lung cancer (NSCLC). Methods and Materials: Between 2001 and 2006, 373 patients (298 men and 75 women, median age 65 years) with brain metastases from NSCLC underwent GKRS. All of them had KPS ≥ 60%, eight or fewer brain metastases, confirmed histopathological diagnosis and recent work-up (3. Median marginal dose was 22.5 Gy at 50% isodose.; median 10 Gy and 12 Gy isodose volumes were 30.8 cm3 and 15.8 cm3, respectively. Follow-up with MRI was performed every 3 months. Overall survival data were collected from internal database, telephone interviews, and identifying registries. Results: Mean follow-up after GKRS was 51 months (range, 6 to 96 months); mean overall survival was 14.2 months. Of 373 patients, 29 were alive at time of writing, 104 had died of cerebral progression, and 176 had died of systemic progression. In 64 cases it was not possible to ascertain the cause. Univariate and multivariate analysis were adjusted for the following: RPA class, surgery, WBRT, age, gender, number of lesions, median tumor volume, median peripheral dose, and 10 Gy and 12 Gy volumes. Identified RPA class and overall tumor volume >5 cc were the only two covariates independently predictive of overall survival in patients who died of cerebral progression. Conclusions: Global volume of brain disease should be the main parameter to consider for performing GKRS, which is a first-line therapy for patient in good general condition and controlled systemic disease.

  13. Microinvasion of liver metastases from colorectal cancer: predictive factors and application for determining clinical target volume

    International Nuclear Information System (INIS)

    This study evaluates the microscopic characteristics of liver metastases from colorectal cancer (LMCRC) invasion and provides a reference for expansion from gross tumor volume (GTV) to clinical targeting volume (CTV). Data from 129 LMCRC patients treated by surgical resection at our hospital between January 2008 and September 2009 were collected for study. Tissue sections used for pathology and clinical data were reviewed. Patient information used for the study included gender, age, original tumor site, number of tumors, tumor size, levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199), synchronous or metachronous liver metastases, and whether patients received chemotherapy. The distance of liver microinvasion from the tumor boundary was measured microscopically by two senior pathologists. Of 129 patients evaluated, 81 (62.8 %) presented microinvasion distances from the tumor boundary ranging between 1.0 − 7.0 mm. A GTV-to-CTV expansion of 5, 6.7, or 7.0 mm was required to provide a 95, 99, or 100 % probability, respectively, of obtaining clear resection margins by microscopic observation. The extent of invasion was not related to gender, age, synchronous or metachronous liver metastases, tumor size, CA199 level, or chemotherapy. The extent of invasion was related to original tumor site, CEA level, and number of tumors. A scoring system was established based on the latter three positive predictors. Using this system, an invasion distance less than 3 mm was measured in 93.4 % of patients with a score of ≤1 point, but in only 85.7 % of patients with a score of ≤2 points. The extent of tumor invasion in our LMCRC patient cohort correlated with original tumor site, CEA level, and number of tumors. These positive predictors may potentially be used as a scoring system for determining GTV-to-CTV expansion

    The blood-brain barrier (BBB) is compromised in brain metastases, allowing for enhanced drug permeation into brain. The extent and heterogeneity of BBB permeability in metastatic lesions is important when considering the administration of chemotherapeutics. Since permeability characteristics have been described in limited experimental models of brain metastases, we sought to define these changes in five brain-tropic breast cancer cell lines: MDA-MB-231BR (triple negative), MDA-MB-231BR-HER2, JIMT-1-BR3, 4T1-BR5 (murine), and SUM190 (inflammatory HER2 expressing). Permeability was assessed using quantitative autoradiography and fluorescence microscopy by co-administration of the tracers (14)C-aminoisobutyric acid (AIB) and Texas red conjugated dextran prior to euthanasia. Each experimental brain metastases model produced variably increased permeability to both tracers; additionally, the magnitude of heterogeneity was different among each model with the highest ranges observed in the SUM190 (up to 45-fold increase in AIB) and MDA-MB-231BR-HER2 (up to 33-fold in AIB) models while the lowest range was observed in the JIMT-1-BR3 (up to 5.5-fold in AIB) model. There was no strong correlation observed between lesion size and permeability in any of these preclinical models of brain metastases. Interestingly, the experimental models resulting in smaller mean metastases size resulted in shorter median survival while models producing larger lesions had longer median survival. These findings strengthen the evidence of heterogeneity in brain metastases of breast cancer by utilizing five unique experimental models and simultaneously emphasize the challenges of chemotherapeutic approaches to treat brain metastases.

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

    International Nuclear Information System (INIS)

    Objective: To investigate effect of radioiodine therapy on pulmonary metastases from well-differentiated thyroid cancer. Methods: Fifty-eight cases of pulmonary metastases were studied utilizing chest X-ray, pulmonary function test and 99Tcm-DTPA aerosol clearance examination. Results: The data of pulmonary function test were of no difference between groups of various radiation doses cumulation (P > 0.05). The differences of vital capacity (VC), fast vital capacity (FVC) and forced expiratory volume in one second (FEV1) were not remarkable between the two groups of male or female patients (P > 0.05), but the difference of maximal volume ventilation (MVV) was P 99Tcm-DTPA aerosol clearance rates between various groups were of no difference (P > 0.05). Only for one female, 43 years old who had received an accumulative dose of 51.8 GBq radioiodine over an 8-yr period, her pulmonary function test showed evidence of restrictive lung disease, chest X-ray showed haziness and DTPA half-time clearance was 26.4 min, which is suggestive of interstitial fibrosis. Conclusion: The cumulative dose of radioiodine and gender of the patients had not statistically significant effects on the pulmonary function. Interstitial fibrosis must be carefully watched when the cumulative radioiodine dose is over 37 GBq

  18. Minimally invasive treatment of peristomal metastases from gastric cancer at an ileostomy site by electrochemotherapy

    International Nuclear Information System (INIS)

    Peristomal metastases are rare, but potentially associated with relevant morbidity. Surgical resection, followed by stoma relocation, represent the gold standard in most patients. We describe electrochemotherapy (ECT), a minimally invasive method for locally-enhancing drug delivery by means of electric pulses, as an alternative approach. A 49-year-old man with advanced gastric cancer developed skin metastases around an ileostomy site. The ulcerated and oozing tumor growth impaired patient’s quality of life due to continuous trouble in fitting the ostomy appliance, its poor adherence and consequent stools spillage. ECT consisted of a 20-minute course under mild general sedation. A bleomycin bolus of 15 000 IU/m2 was followed by the percutaneous application of multiple, 1.5 ms -long electric pulses by means of a needle electrode. Post ECT course was uneventful and the patient was discharged on the same day. After one week, tumor nodules were flattened and partial tumor regression was appreciable at one-month follow-up. More importantly, peristomal skin conditions significantly improved, thus allowing for an effective application of the ostomy appliance during the following moths, until patient’s death. This report suggests the feasibility of ECT as a minimally invasive approach for peristomal tumors. In selected cases, ECT, by achieving a rapid tumor control, may ensure effective ostomy management and preserve patients’ quality of life

    Pre-therapeutic prediction of outcome is important for clinicians and patients in determining whether selective internal radiation therapy (SIRT) is indicated for hepatic metastases of colorectal cancer (CRC). Pre-therapeutic characteristics of 100 patients with colorectal liver metastases (CRLM) treated by radioembolization were analyzed to develop a nomogram for predicting survival. Prognostic factors were selected by univariate Cox regression analysis and subsequent tested by multivariate analysis for predicting patient survival. The nomogram was validated with reference to an external patient cohort (n = 25) from the Bonn University Department of Nuclear Medicine. Of the 13 parameters tested, four were independently associated with reduced patient survival in multivariate analysis. These parameters included no liver surgery before SIRT (HR:1.81, p = 0.014), CEA serum level ≥ 150 ng/ml (HR:2.08, p = 0.001), transaminase toxicity level ≥2.5 x upper limit of normal (HR:2.82, p = 0.001), and summed computed tomography (CT) size of the largest two liver lesions ≥10 cm (HR:2.31, p < 0.001). The area under the receiver-operating characteristic curve for our prediction model was 0.83 for the external patient cohort, indicating superior performance of our multivariate model compared to a model ignoring covariates. The nomogram developed in our study entailing four pre-therapeutic parameters gives good prediction of patient survival post SIRT. (orig.)

These parameters included no liver surgery before SIRT (HR:1.81, p = 0.014), CEA serum level ≥ 150 ng/ml (HR:2.08, p = 0.001), transaminase toxicity level ≥2.5 x upper limit of normal (HR:2.82, p = 0.001), and summed computed tomography (CT) size of the largest two liver lesions ≥10 cm (HR:2.31, p < 0.001). The area under the receiver-operating characteristic curve for our prediction model was 0.83 for the external patient cohort, indicating superior performance of our multivariate model compared to a model ignoring covariates. The nomogram developed in our study entailing four pre-therapeutic parameters gives good prediction of patient survival post SIRT. (orig.)

  1. Prognostic Significance of PSA, Gleason Score, Bone Metastases in Patients with Metastatic Prostate Cancer Under Palliative Androgen Deprivation Treatment

    International Nuclear Information System (INIS)

    Objective: The aim of this study was to evaluate the prognostic significance of each of the following in the development and progression of hormonal refractory disease in patients with metastatic prostate cancer under hormonal palliative treatment: The initial serum level prostate specific antigen (PSA), the Gleason score (GS), the presence of bone metastases with or without visceral metastases, and the PSA decline. Patients and Methods: During the time period from January 2005 to December 2008, a total of 92 patients with newly diagnosed, histologically confirmed metastatic prostate cancer (MPC) were under palliative androgen deprivation therapy. The age range was 52 to 85 years with a mean age of 66.2±7.9 years. MPC was diagnosed histologically after transrectal ultrasonography guided biopsy. The Gleason score assessment was determined by low power microscopic examination. Metastases were confirmed by positive bone scintigraphy with 925 MBq 99mTc-MDP using a tomographic gamma camera, computerized axial tomography or magnetic resonance imagining. Measurements of PSA levels were conducted by the radioimmunoassay method. The influences of the following prognostic factors were evaluated: The initial serum level of prostate specific antigen (PSA), the Gleason score (GS), the presence of bone metastases with or without visceral metastases, and the PSA decline, on the time to disease progression. Results: The time to progression was significantly delayed in patients with initial PSA level £50 ng/ml (median: 32 months), Gleason Score £7 (median: 33 months), bone metastases only (median: 30 months) and PSA level normalization within 6 months (median: 30 months) compared to that of patients with initial PSA level >50 ng/ml (median: 24 months), Gleason Score >7 (median: 24 months), bone, distant lymph nodes and/or visceral metastases (median: 24 months), PSA level decline (median: 18 months) (p-values were 0.002, 6 sites bone metastases (median: 28 months) (p=0

  2. Factors influencing the uptake of a new monoclonal antibody (LICR-LON-M8) in skeletal metastases from breast carcinoma

    International Nuclear Information System (INIS)

    Preliminary studies with an In 111 labelled monoclonal antibody to Human Milk Fat Globule Membrane (LICR-LON-M8) showed successful localisation of breast carcinoma bone metastases without the necessity of blood background subtraction. A further 18 patients with breast carcinoma have been investigated to elucidate in more detail the factors influencing the uptake of antibody. All patients had serial bone scintigrams and X-rays in addition to the antibody scintigrams at 18-48 hours after injection. The M8 was labelled with In 111 DTPA. Thirteen sites were positive on the antibody scintigrams alone. In X-ray positive lesions (25) antibody scintigrams were more often positive in lytic (15) than sclerotic (5) or mixed (5) lesions. In nine cases the focal disease was smaller than 2 cm but five larger focal lesions were negative. Correlative studies showed that positive antibody scintigrams were found in new lesions or progressive disease preceding X-ray or positive bone scintigrams. In a few patients, negative antibody scintigrams were found with positive X-ray or bone scintigrams following successful therapy. The study was particularly valuable in two patients differentiating malignant disease from other causes of positive bone scintigrams or X-rays

    2006-01-01

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

  4. Surgery and radiotherapy of brain metastases in breast cancer patients - an analysis of survival and prognostic factors

    International Nuclear Information System (INIS)

    The study assesses the results of radical neurosurgical treatment and adjuvant radiotherapy of one or two brain metastases in breast cancer patients. The survival analyses were performed according to different factors and in different prognostic class. We analyzed 31 breast cancer patients with one or two metastatic brain tumours treated at Maria Sklodowska-Curie Memorial Cancer Center and Institute of Oncology (MSMCC) between the years 1998 and 2005. The patients underwent neurosurgical excision with radical intent, followed by whole brain irradiation. Overall survival from the time of the diagnosis of brain metastases has been assessed both in the entire group and in the different prognostic groups. Median survival calculated for the entire group was 12 months (range: 2-77 months) while in the different prognostic groups it reached: 28 months (range: 2-77 months) for class I patients, 14 months (range: 5-17 months) for class II patients and 3 months (range: 3-8 months) for class III patients. We had observed that prognosis was significantly better in patients with a good performance status, with a single brain metastases and without the symptoms of active extracranial disease. The time lapse from the diagnosis of breast cancer to the development of brain metastases, the localization of the metastatic mass in the brain and systematic treatment did not affect survival. The overall survival of breast cancer patients with brain metastases treated neurosurgically with adjuvant whole brain radiotherapy is significantly longer in case of prognostic class I patients, as compared to prognostic class II and III patients. The patients to benefit the most from surgery and irradiation were in good overall condition, without symptoms of active extracranial disease and with a single metastatic brain tumour. In the case of such patients combined therapy (surgery and whole brain, radiotherapy) should always be considered, as radiotherapy alone may not allow to achieve comparable

    Common and deadly complications of non-small cell lung cancer (NSCLC) are brain metastases (BM). BM portends a poorer prognosis with limited effective treatment options and current management strategies present several challenges from iatrogenic complications of supportive medications, optimal delivery of drug across the blood-brain barrier, and preservation of neurocognitive function. Long term side effects and survivorship issues have become more evident in the era of targeted therapy where a systemic disease is much better controlled. Targeted therapies and immunotherapy are beginning to provide improvements in responses and survival rates. With further advancements and experience, our knowledge in this era of precision medicine will likely lead to strides in improving the quality of life and overall survival of patients with BM from NSCLC. In this review, we present the most recent updates in treatment of BM in NSCLC in regards to targeted and immunotherapy. PMID:26709658

    Advances in surgical and medical treatments have significantly changed the management of colorectal cancer liver metastases (CRCLMs). In particular, new drugs and modern combination chemotherapy regimens, together with the improvement of surgical techniques, allow a potentially curative approach in an increasing number of patients. Nevertheless, there is no strong evidence for an optimal treatment strategy for CRCLMs, mainly because of the extensive heterogeneity in the patients. In fact, although we consider them a population, they represent different clinical and biological subtypes requiring different approaches. Furthermore, results from different studies in this setting may be difficult to interpret, also because the definitions of different patient subgroups are unclear and overlapping. In this review we discuss the results of clinical trials evaluating the role of chemotherapy in the multimodal management of CRCLMs, in either the pre- or postoperative setting. Then we identify three main categories of CRCLM patients, providing clinical recommendations for each. PMID:22964298

    A microbeam synchrotron X-ray fluorescence ({mu}SRXRF) technique has been used to determine the localization and the relative concentrations of Zn, Cu, Fe and Ca in primary colorectal cancer and secondary colorectal liver metastases. 24 colon and 23 liver samples were examined, all of which were formalin fixed tissues arranged as microarrays of 1.0 mm diameter and 10 {mu}m thickness. The distribution of these metals was compared with light transmission images of adjacent sections that were H and E stained to reveal the location of the cancer cells. Histological details were provided for each sample which enable concentrations of all elements in different tissue types to be compared. In the case of liver, significant differences have been found for all elements when comparing tumour, normal, necrotic, fibrotic, and blood vessel tissues (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have also been found to be significantly different among tumour, necrotic, fibrotic, and mucin tissues in the colon samples (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have been compared between primary colorectal samples and colorectal liver metastases. Concentration of Zn, Cu, Fe and Ca are higher in all types of liver tissues compared to those in the colon tissues. Comparing liver tumour and colon tumour samples, significant differences have been found for all elements (Mann Whitney, P<0.0001). For necrotic tissues, significant increase has been found for Zn, Ca, Cu and Fe (Mann Whitney, P<0.0001 for Fe and Zn, 0.014 for Ca, and 0.001 for Cu). The liver fibrotic levels of Zn, Ca, Cu and Fe were higher than the fibrotic colon areas (independent T test, P=0.007 for Zn and Mann Whitney test P<0.0001 for Cu, Fe and Ca). For the blood vessel tissue, the analysis revealed that the difference was only significant for Fe (P=0.009) from independent T test.

    Background Differentiated thyroid cancer (DTC) is a common primary cancer for spinal metastases (SM).The treatments for DTC spinal metastases (SM) have evolved from simple surgery and radiotherapy to a multidisciplinary comprehensive therapeutic strategy of combined spinal surgery,general surgery,radiotherapy,nuclear medicine and endocrinology.The purpose of this study was to discuss the efficacy and prognosis associated with different surgical treatments of SM patients with DTC.Methods A total of 21 consecutive patients with SM of DTC that were treated between 1999 and 2013 were studied.Biopsy was routinely performed to achieve the pathological diagnosis before treatment.Three patients underwent total spondylectomy intralesionally or piecemeally,and 18 had curettage.Postoperative recurrence and survival times were analyzed by the Kaplan-Meier methods.Results Nineteen patients (90%) had an average of 42.7 months (range,7-170 months) follow-up.The median visual analogue scale for pain reduced from 5 points to 1 point (P <0.01),and the median Karnofsky performance score increased from 70 to 90 points after surgery (P <0.01).Seventeen patients with neurological deficits attained improvements after surgeries,of at least one level according to the Frankel classification (P <0.01).Eight patients with curettage had recurrence.Four patients died of DTC,12 patients lived with disease,and three patients were disease-free.No significant effects on postoperative recurrence or survival were observed between surgery combined with conservative treatment,total spondylectomy,the number of bone metastases and visceral metastasis.Conclusions DTC-SM have a relatively favorable prognosis,and curettage and stabilization can effectively relieve the pain and improve the quality of life and neurological status of the patients.For patients with Tomita scores of <3,total spondylectomy may have better clinical outcomes.Comprehensive therapeutic strategies including surgery

  13. Prognostic indices in stereotactic radiotherapy of brain metastases of non-small cell lung cancer

    International Nuclear Information System (INIS)

    Our purpose was to analyze the long-term clinical outcome and to identify prognostic factors after Linac-based stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) on patients with brain metastases (BM) from non-small cell lung cancer (NSCLC). We performed a retrospective analysis of survival on 90 patients who underwent SRS or FSRT of intracranial NSCLC metastases between 04/2004 and 05/2014 that had not undergone prior surgery or whole brain radiotherapy (WBRT) for BM. Follow-up data was analyzed until May 2015. Potential prognostic factors were examined in univariable and multivariable analyses. The Golden Grading System (GGS), the disease-specific graded prognostic assessment (DS-GPA), the RADES II prognostic index as well as the NSCLC-specific index proposed by Rades et al. in 2013 (NSCLC-RADES) were calculated and their predictive values were tested in univariable analysis. The median follow-up time of the surviving patients was 14 months. The overall survival (OS) rate was 51 % after 6 months and 29.9 % after 12 months. Statistically significant factors of better OS after univariable analysis were lower International Union Against Cancer (UICC) stage at first diagnosis, histology of adenocarcinoma, prior surgery of the primary tumor and lower total BM volume. After multivariable analysis adenocarcinoma histology remained a significant factor; higher Karnofsky Performance Score (KPS) and the presence of extracranial metastases (ECM) were also significant. The RADES II and the NSCLC-RADES indices were significant predictors of OS. However, the NSCLC-RADES failed to differentiate between intermediate- and low-risk patients. The DS-GPA and GGS were not statistically significant predictors of survival in univariable analysis. The ideal prognostic index has not been defined yet. We believe that more specific indices will be developed in the future. Our results indicate that the histologic subtype of NSCLC could add to the prognostic

  14. Distant Metastases Following Permanent Interstitial Brachytherapy for Patients With Clinically Localized Prostate Cancer

    International Nuclear Information System (INIS)

    Purpose: Recent publications have suggested high-risk patients undergoing radical prostatectomy have a lower risk of distant metastases and improved cause-specific survival (CSS) than patients receiving definitive external beam radiation therapy (XRT). To date, none of these studies has compared distant metastases and CSS in brachytherapy patients. In this study, we evaluate such parameters in a consecutive cohort of brachytherapy patients. Methods and Materials: From April 1995 to June 2007, 1,840 consecutive patients with clinically localized prostate cancer were treated with brachytherapy. Risk groups were stratified according to National Comprehensive Cancer Network ( (www.nccn.org)) guidelines. Subgroups of 658, 893, and 289 patients were assigned to low, intermediate, and high-risk categories. Median follow-up was 7.2 years. Along with brachytherapy implantation, 901 (49.0%) patients received supplemental XRT, and 670 (36.4%) patients received androgen deprivation therapy (median duration, 4 months). The mode of failure (biochemical, local, or distant) was determined for each patient for whom therapy failed. Cause of death was determined for each deceased patient. Multiple parameters were evaluated for impact on outcome. Results: For the entire cohort, metastases-free survival (MFS) and CSS at 12 years were 98.1% and 98.2%, respectively. When rates were stratified by low, intermediate, and high-risk groups, the 12-year MFS was 99.8%, 98.1%, and 93.8% (p < 0.001), respectively. CSS rates were 99.8%, 98.0%, and 95.3% (p < 0.001) for low, intermediate, and high-risk groups, respectively. Biochemical progression-free survival was 98.7%, 95.9% and 90.4% for low, intermediate, and high-risk patients, respectively (p < 0.001). In multivariate Cox-regression analysis, MFS was mostly closely related to Gleason score and year of treatment, whereas CSS was most closely associated with Gleason score. Conclusions: Excellent CSS and MFS rates are achievable with high

    OBJECTIVE To evaluate the safety and effectiveness of treatment of hepatic metastases from colorectal cancer using high-intensity focused ultrasound (HIFU). METHODS Thirty-one lesions in 18 patients with hepatic metastases from colorectal cancer after colectomy were treated with HIFU therapy. The vital signs, function of the vital organs, complications and pathological outcome were studied using imaging examinations such as CT or MRI. RESULTS The vital signs of all patients remained stable and their liver and kidney functions normal. Two of the 18 patients were not followed-up. After a mean follow-up of 16.1 months (6-38 months), 13 survived. The survival rates at the 12th and 18th months were 83.3% and 66.7%, respectively. The median survival rate was 16 months. Among the 25 lesions followed-up, 17 shrank over 50%, 5 grew new metastases and superficial degree II skin injury occurred in 8. CONCLUSION HIFU is a safe, effective and non-invasive option for the treatment of hepatic metastases from colorectal cancer.

  16. Evaluation of diagnostic procedures such as plain-film scintigraphy and MR imaging for spinal metastases in relation to biological characteristics in breast cancer

    International Nuclear Information System (INIS)

    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 α 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 α 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)

  17. The stability of osseous metastases of the spine in lung cancer – a retrospective analysis of 338 cases

    International Nuclear Information System (INIS)

    The objective of this retrospective analysis is to systematically assess osseous lesions on the basis of a validated scoring system in terms of stability and fractures prior to and following radiotherapy in 338 lung cancer patients with bone metastases in the vertebral column. The stability of 338 patients with 981 osteolytic metastases in the thoracic and lumbar spine was evaluated retrospectively on the basis of the Taneichi-Score between January 2000 and January 2012. 64% (215 patients) were classified stable prior to radiotherapy. Of the stable osseous metastases, none were rated unstable in the further course (p < 0.001, McNemar test). Of the 123 patients in whom the metastases were classified unstable prior to radiotherapy, 21 patients (17%) were classified stable after three months, and 30 patients (24%) stable after six months. A pathological fracture was diagnosed in 62 patients (18%) prior to radiotherapy. Regarding cases of osteolytic metastases of the vertebral bodies in which no fractures could be detected prior to the start of therapy, fractures occurred in 2% of all patients (n = 7) within six months following radiotherapy. Our analysis demonstrated that pathological fractures following radiotherapy occur in the very minority of vertebral lesions for patients with a favorable outcome. The use of a systematic radiological scoring system to classify osteolytic metastases of the vertebral column has shown to be feasible in daily routine. Prospective clinical trials are warranted in order to analyse, to what extent patients with osseous metastases can be mobilized by physiotherapy for strengthening the paravertebral muscles before radiotherapy effects can be measured by means of radiological recalcification

    Full Text Available Abstract Background The transcription factor SOX2, which is involved in the induction of pluripotent stem cells and contributes to colorectal carcinogenesis, is associated with a poor prognosis in colon cancer (CC. Furthermore, SOX2 is a repressor of the transcriptional activity of β-catenin in vitro. Since the majority of CC develop via an activation of the Wnt/β-catenin signalling pathway, indicated by nuclear expression of β-catenin, we wanted to investigate the expression patterns of SOX2 and β-catenin and correlate them with the occurrence of lymph node and distant metastases as indicators of malignant progression. Methods The expression of SOX2 and β-catenin was investigated in a case control study utilizing a matched pair collection (N = 114 of right-sided CCs with either corresponding distant metastases (N = 57 or without distant spread (N = 57 by applying immunohistochemistry. Results Elevated protein expression of SOX2 significantly correlated with the presence of lymph node- (p = 0.006 and distant metastases (p = 0.022. Nuclear β-catenin expression correlated significantly only with distant metastases (p = 0.001. Less than 10% of cases showed a coexpression of high levels of β-catenin and SOX2. The positivity for both markers was also associated with a very high risk for lymph-node metastases (p = 0.007 and distant spread (p = 0.028. Conclusion We demonstrated that increased expression of either SOX2 or nuclear β-catenin are associated with distant metastases in right-sided CC. Additionally, SOX2 is also associated with lymph-node metastases. These data underline the importance of stemness-associated markers for the identification of CC with high risk for distant spread.

    International Nuclear Information System (INIS)

    Provide evaluation of investigation of kinetics of 153Sm-oksabifor in metastases of cancer the results of complex scintigraphic investigations of 26 patients who were treated by radionuclide therapy were analyzed. The angioscintigraphy during 60 seconds, dynamic scintigraphy during 60-90 minutes and whole body scanning after intravenous bolus injection of 4130-4950 MBq of the radiopharmaceutical in sequence were made. Considerable variability of indices of the radiopharmaceutical kinetics was determined. The features of angioscintigrams from bone metastases with intensive accumulation of the radiopharmaceutical are a short descending segment or its absents and passing an ascending segment into plateau or slowly ascending curve, which are determined the radiopharmaceutical fixation in metastases during first passing the bolus through the vessels. Character of the radiopharmaceutical fixation at angioscintigraphy may be a prognostic factor of the efficacy of radionuclide therapy

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

    International Nuclear Information System (INIS)

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

    Full Text Available Gap junctions are specialized cell membrane channels composed of connexins (Cxs, which mediate the direct passage of small molecules between adjacent cells. They are involved in the regulation of cell cycle, cell signaling and differentiation as well as probably invasion and metastasis. Up to now, Cx32 status in human breast cancer has not been studied. Consequently, the aim of the present study was the evaluation of the expression of connexin 32 (Cx32 in primary breast tumors (PTs and matched-paired metastases to lymph nodes (MLNs in correlation with selected clinicopathological features. Tissue samples from 79 women were examined by immunohistochemistry, using the streptavidin-biotin-peroxidase complex technique for Cx32. Cytoplasmic expression of Cx32 was detected in 31 of 79 breast cancers (39.2%. Both epithelial and myoepithelial cells of normal ducts adjacent to the tumor did not express Cx32. Increased expression of studied Cx was observed in metastases to lymph nodes relative to primary tumors. Additionally, Cx32-negative primary tumors developed Cx32-positive metastases. Statistical comparisons of Cx32 expression in the matched pairs indicate that this protein significantly increased in lymph node metastases compared to primary tumors (p<0.001. The expression of Cx32 in primary breast cancer was not statistically associated with age of patients, tumor size, lymph node status, but we observed a tendency toward association between Cx32 expression and histological differentiation. In conclusion, transformed cells may have an ability to produce Cxs also atypical for normal cells. Increased expression of Cx32 in metastases to the lymph nodes might reflect alteration in connexin gene transcription during breast carcinogenesis and finally, it may be a sign of more malignant phenotype of cancerous cells.

    Skeletal muscle atrophy in cancer cachexia is mediated by the interaction between muscle stem cells and various tumor factors. Although Notch signaling has been known as a key regulator of both cancer development and muscle stem cell activity, the potential involvement of Notch signaling in cancer cachexia and concomitant muscle atrophy has yet to be elucidated. The murine K7M2 osteosarcoma cell line was used to generate an orthotopic model of sarcoma-associated cachexia, and the role of Notc...

  5. Clinical results of N0 tongue cancer treated with interstitial brachytherapy and management of occult cervical node metastases

    International Nuclear Information System (INIS)

    One hundred patients with T1-2N0 squamous cell carcinoma of the oral tongue were treated with interstitial brachytherapy between 1962 and 1983. The patients were followed for more than two years. The cumulative 5-year survival rate was 89% in T1N0 and 66% in T2N0. The relapse-free survival rate was 88% in T1N0 and 51% in T2N0. The 2-year local control rate in the primary site was 100% in T1N0 and 73% in T2N0. Cervical node metastases developed in 41% (T1N0: 33%, T2N0: 43%) of the patients. The 5-year survival rate for patients with subsequent cervical node metastases was 42%, and 92% for patients without them (p2 + PEP 6 mg/m2 x 5 days), the 2-year local control rate was 90%, the incidence of cervical node metastases was 38%, and the incidence of distant metastases was 15%. In 15 patients without chemotherapy, the corresponding figures were 93%, 20% and 7%. No statistically significant difference between the two groups was found. In conclusion, the development of cervical node metastasis worsens the prognosis of patients with T1-2N0 oral tongue cancer treated with interstitial brachytherapy. The combination with prophylactic neck irradiation or chemotherapy failed to decrease the incidence of cervical node metastases or improve survival rate. (J.P.N.)

    Objective: to evaluate the comparative impact of magnetic resonance imaging and bone scintigraphy in bone metastases of breast cancer. Methods and patients: in 81 patients with histologically proven breast cancer magnetic resonance imaging of the axial skeleton and whole-body bone scintigraphy had been performed. Images were retrospectively reviewed and compared for detection of metastases, extent of metastatic disease and therapeutic implications according to the patients' records. Results: about 54/81 (67%) patients revealed bone metastases. In 7/54 (13%) patients with bone metastases, scintigraphy was false negative. In one patient a solitary sternal metastases was seen. In 26/53 [49%] patients with spinal metastases, magnetic resonance imaging showed more extensive disease. Local radiotherapy or surgery was indicated in ten patients with metastases not evident in bone scintigraphy, in 20 patients with positive results by both imaging modalities and in six patients with metastases of pelvis imaged by bone scintigraphy only. Conclusion: magnetic resonance imaging of the axial skeleton and pelvis appears superior for staging as only one patient had metastases merely outside the axial skeleton and local therapy was indicated even in spinal regions negative in bone scintigraphy.

    Full Text Available Cytogenetic and molecular genetic analyses of colorectal adenomas and carcinomas have shown that loss of the distal part of chromosome arm 1p is common, particularly in tumors of the left colon. Because the importance of 1p loss in colorectal cancer metastases is unknown, we compared the frequency, exact site and extent of ip deletions in primary carcinomas (n=28, local recurrences (n=19 and metastases (n=33 from 67 colorectal cancer patients using 14 markers in an allelic imbalance study. Loss of 1p was found in 50% of the primary carcinomas, 33% of the local recurrences, and 64% of the metastases, revealing a significant difference between the local recurrences and the metastases (P=.04. The smallest region of 1p deletion overlap (SRO defined separately for each group of lesions had the region between markers Di S2647 and D1 S2644, at 1 p35-36, in common. The genes PLA2G2A (1p35.1-36 and TP73 (1p36.3 were shown to lie outside this consistently lost region, suggesting that neither of them are targets for the 1p loss. In the second part of the study, microdissected primary carcinomas and distant metastases from the same colorectal cancer patients (n=18 were analyzed, and the same 1p genotype was found in the majority of patients (12/18, 67%. The finding that primary carcinoma cells with metastatic ability usually contain 1p deletions, and that some cases lacking 1p alterations in the primary tumor acquire such changes during growth of a metastatic lesion, supports the notion that 1p loss may be important both early and late in colorectal carcinogenesis, with the apparent exception of local recurrences.

    Pelvic lymphadenectomy in early-stage endometrial cancer is controversial, but the findings influence prognosis and treatment decisions. Noninvasive tools to identify women at high risk of lymph node metastasis can assist in determining the need for lymph node dissection and adjuvant treatment for patients who do not have a lymph node dissection performed initially. A retrospective review of surgical pathology was conducted for endometrioid endometrial adenocarcinoma at our institution. Univariate and multivariate logistic regression analysis of selected pathologic features were performed. A nomogram to predict for lymph node metastasis was constructed. From August 1996 to October 2013, 296 patients underwent total abdominal or laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and selective lymphadenectomy for endometrioid endometrial adenocarcinoma. Median age at surgery was 62.7 yr (range, 24.9-93.6 yr). Median number of lymph nodes removed was 13 (range, 1-72). Of all patients, 38 (12.8%) had lymph node metastases. On univariate analysis, tumor size ≥4 cm, grade, lymphovascular space involvement, cervical stromal involvement, adnexal or serosal or parametrial involvement, positive pelvic washings, and deep (more than one half) myometrial invasion were all significantly associated with lymph node involvement. In a multivariate model, lymphovascular space involvement, deep myometrial invasion, and cervical stromal involvement remained significant predictors of nodal involvement, whereas tumor size of ≥4 cm was borderline significant. A lymph node predictive nomogram was constructed using these factors. Our nomogram can help estimate risk of nodal disease and aid in directing the need for additional surgery or adjuvant therapy in patients without lymph node surgery. Lymphovascular space involvement is the most important predictor for lymph node metastases, regardless of grade, and should be consistently assessed. PMID:26598977

    Background Squamous cell carcinoma (SCC) of the tongue is one of the most common cancers in the oral and maxillofacial region. To provide clinical evidence for selective neck dissection in management of cN0 patients by analyzing the characteristics and correlation of factors of occult cervical lymph node metastases (OCLNM) in patients with SCC of the tongue.Methods From 2002 to 2006, 100 consecutive patients with SCC of the tongue were reviewed by analyzing the characteristics of OCLNM, diameter of the tumor, T classifications, depth of invasion, forms of growth, pathological grade and degree of differentiation.Results The rate of OCLNM in 100 patients with SCC of the tongue was 22%. The most common region with OCLNM was level Ⅱ in the ipsilateral neck, followed by levels Ⅰ and Ⅲ. There were 51.61% (16/31) of OCLNM in level Ⅱ and 87.10% (27/31) of OCLNM in levels Ⅰ-Ⅲ. There was no significant correlation between the diameter of tumor and OCLNM (P >0.05). OCLNM was statistically significantly correlated with the depth of invasion, forms of growth, pathological grade and degree of differentiation (P <0.05). The rate of occult metastases increased with the increased pathological grade,the decreased degree of differentiation and the increased depth of invasion.Conclusions The most common regions with OCLNM in cN0 patients with SCC of the tongue were levels Ⅰ-Ⅲ in the ipsilateral neck. Supraomohyoid neck dissection should be the elective treatment to the neck in patients with cN0 SCC of the tongue by consideration of the clinical and pathological factors for the depth of invasion, forms of growth, pathological grade, and degree of differentiation.

  12. Carbon ion radiotherapy for oligo-recurrent lung metastases from colorectal cancer: a feasibility study

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the efficacy and feasibility of carbon ion radiotherapy (CIRT) for oligo-recurrent lung tumors from colorectal cancer (CRC). From May 1997 to October 2012, 34 consecutive patients with oligo-recurrent pulmonary metastases from CRC were treated with CIRT. The patients were not surgical candidates for medical reasons or patient refusal. Using a respiratory-gated technique, carbon ion therapy was delivered with curative intent using 4 coplanar beam angles. A median dose of 60 GyE (range, 44–64.8 GyE) was delivered to the planning target volume (PTV), with a median daily dose of 15 GyE (range, 3.6–44 GyE). Treatment outcome was analyzed in terms of local control rate (LCR), survival rate, and treatment-related complications. In total, 34 patients with 44 oligo-recurrent pulmonary lesions were treated with CIRT. Median follow-up period was 23.7 months. The 2- and 3-year actuarial LCRs of the treated patients were 85.4% ± 6.2% and 85.4% ± 6.2%, respectively. Overall survival was 65.1% ± 9.5% at 2 years, and 50.1% ± 10.5% at 3 years. Although survival rates were relatively worse in the subsets of patients aged < 63 years or with early metastasis (< 36 months after resection of primary site), these factors were not significantly correlated with overall survival (P = 0.13 and 0.19, respectively). All treatment-related complications were self-limited, without any grade 3–5 toxicity. CIRT is one of the most effective nonsurgical treatments for colorectal lung metastases, which are relatively resistant to stereotactic body radiotherapy. CIRT is considered to be the least invasive approach even in patients who have undergone repeated prior thoracic metastasectomies

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

  14. Expression of androgen receptor splice variants in prostate cancer bone metastases is associated with castration-resistance and short survival.

    Directory of Open Access Journals (Sweden)

    Emma Hörnberg

    Full Text Available BACKGROUND: Constitutively active androgen receptor variants (AR-V lacking the ligand binding domain (LBD may promote the development of castration-resistant prostate cancer (CRPC. The expression of AR-Vs in the clinically most important metastatic site, the bone, has, however, not been well documented. Our aim was therefore to compare levels of AR-Vs in hormone-naive (HN and CRPC bone metastases in comparison to primary PC and non-malignant prostate tissue, as well as in relation to AR protein expression, whole-genome transcription profiles and patient survival. METHODOLOGY/PRINCIPAL FINDINGS: Hormone-naïve (n = 10 and CRPC bone metastases samples (n = 30 were obtained from 40 patients at metastasis surgery. Non-malignant and malignant prostate samples were acquired from 13 prostatectomized men. Levels of full length AR (ARfl and AR-Vs termed AR-V1, AR-V7, and AR-V567es mRNA were measured with RT-PCR and whole-genome transcription profiles with an Illumina Beadchip array. Protein levels were examined by Western blotting and immunohistochemistry. Transcripts for ARfl, AR-V1, and AR-V7 were detected in most primary tumors and metastases, and levels were significantly increased in CRPC bone metastases. The AR-V567es transcript was detected in 23% of the CRPC bone metastases only. A sub-group of CRPC bone metastases expressed LBD-truncated AR proteins at levels comparable to the ARfl. Detectable AR-V567es and/or AR-V7 mRNA in the upper quartile, seen in 1/3 of all CRPC bone metastases, was associated with a high nuclear AR immunostaining score, disturbed cell cycle regulation and short survival. CONCLUSIONS/SIGNIFICANCE: Expression of AR-Vs is increased in CRPC compared to HN bone metastases and associated with a particularly poor prognosis. Further studies are needed to test if patients expressing such AR-Vs in their bone metastases benefit more from drugs acting on or down-stream of these AR-Vs than from therapies inhibiting androgen synthesis.

  15. Relationship Between HER2 Status and Prognosis in Women With Brain Metastases From Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To analyze factors affecting outcomes in breast cancer patients with brain metastases (BM) and characterize the role of HER2 status. Methods and Materials: We identified 264 breast cancer patients treated between 1999 and 2008 for BM. HER2 status was known definitively for 172 patients and was used to define cohorts in which survival and risk factors were analyzed. Results: Kaplan-Meier survival analysis demonstrated improved mean overall survival (105.7 vs. 74.3 months, p < 0.02), survival after diagnosis of BM (neurologic survival, NS) (32.2 vs. 18.9 months, p < 0.01), and survival after treatment with stereotactic radiosurgery (RS) (31.3 vs. 14.1, p < 0.01) in HER2+ patients relative to those with HER2− breast cancer. HER2+ status was an independent, positive prognostic factor for survival on univariate and multivariate hazard analysis (hazard ratio: overall survival = 0.66, 0.18; NS = 0.50, 0.34). Additionally, subgroup analysis suggests that stereotactic radiosurgery may be of particular benefit in patients with HER2+ tumors. Conclusions: Overall survival, NS, and RS are improved in patients with HER2+ tumors, relative to those with HER2− lesions, and HER2 amplification is independently associated with increased survival in patients with BM from breast cancer. Our findings suggest that the prognosis of HER2+ patients may be better than that of otherwise similar patients who are HER2− and that stereotactic radiosurgery may be beneficial for some patients with HER2+ lesions.

  17. Results of radiotherapy of primary lung cancer with reference to metastases in regional lymph nodes

    International Nuclear Information System (INIS)

    The results of radiotherapy in the treatment of primary lung cancer is presented with reference to metastases in regional lymph nodes. The study involved 382 patients with histologically proven lung cancer of all cell types who, between 1945 and 1955, initially underwent definitive radiotherapy with TDFs of more than 70. The evaluable patients comprised 66 for N0, 177 for N1 and 139 for N2. Cumulative five-year survival rates for N0, N1 and N2 were 23.9%, 6.1% and 5.6%, respectively. Although surgical treatment before radiotherapy did not significantly improve a cumulative five-year survival rate for each N category, it kept patients alive longer for the median survival time (month). In 89 patients with involved mediastinal lymph nodes that specific sites were identified at the time of the surgical treatment (pN2), prolonged survival was obtained by radiotherapy if lymphatic spread was absent in the sites of No.1, No.2, No.3, No.5 and No.6. If present, however, none of patients were alive at the post-treatment time of three years. As to 155 patients with stage III disease comprising T3 and/or N2, both cumulative five-year survival rate and median survival time showed better results in the group of N2 disease than those in T3.

    Full Text Available Although cutaneous metastasis occurs usually at the terminal stage of the disease, it may be rarely concurrent with the diagnosis and may also present as the first sign of the illness. A 55-year-old male patient presented with vasculitic-type cutaneous nodular lesions and a necrotic distal phalangeal lesion developed over the last month. He was a tradesman and smoked 40 packets year. On physical examination, he was found to have multiple cutaneous lesions on the skin of the face, limbs, neck, scalp, dorsal side, fingers, subungual side, right leg, and feet. A skin lesion punch biopsy was performed and squamous cell carcinoma metastasis was detected. He was diagnosed as having squamous cell lung cancer with bronchoscopic biopsy. Although it is very rare, cutaneous metastases that is concurrent with the diagnosis of lung cancer may be the first sign of the disease. In patients with suspicious skin lesions, the patient′s age, smoking history, and other symptoms should be evaluated and a biopsy should be performed.

We evaluated CPT-11 and bevacizumab, which can both cross the blood–brain barrier, as combination therapy to treat HER2–neu-positive breast cancer with brain metastases.

    Skeletal muscle atrophy in cancer cachexia is mediated by the interaction between muscle stem cells and various tumor factors. Although Notch signaling has been known as a key regulator of both cancer development and muscle stem cell activity, the potential involvement of Notch signaling in cancer cachexia and concomitant muscle atrophy has yet to be elucidated. The murine K7M2 osteosarcoma cell line was used to generate an orthotopic model of sarcoma-associated cachexia, and the role of Notch signaling was evaluated. Skeletal muscle atrophy was observed in the sarcoma-bearing mice, and Notch signaling was highly active in both tumor tissues and the atrophic skeletal muscles. Systemic inhibition of Notch signaling reduced muscle atrophy. In vitro coculture of osteosarcoma cells with muscle-derived stem cells (MDSCs) isolated from normal mice resulted in decreased myogenic potential of MDSCs, while the application of Notch inhibitor was able to rescue this repressed myogenic potential. We further observed that Notch-activating factors reside in the exosomes of osteosarcoma cells, which activate Notch signaling in MDSCs and subsequently repress myogenesis. Our results revealed that signaling between tumor and muscle via the Notch pathway may play an important role in mediating the skeletal muscle atrophy seen in cancer cachexia. PMID:27378829

    Selection of the optimal surgical and interventional therapies for advanced colorectal cancer liver metastases (CRLM) requires multidisciplinary discussion of treatment strategies early in the trajectory of the individual patient's care. This paper reports on expert consensus on locoregional and interventional therapies for the treatment of advanced CRLM. Resection remains the reference treatment for patients with bilateral CRLM and synchronous presentation of primary and metastatic cancer. Patients with oligonodular bilateral CRLM may be candidates for one-stage multiple segmentectomies; two-stage resection with or without portal vein embolization may allow complete resection in patients with more advanced disease. After downsizing with preoperative systemic and/or regional therapy, curative-intent hepatectomy requires resection of all initial and currently known sites of disease; debulking procedures are not recommended. Many patients with synchronous primary disease and CRLM can safely undergo simultaneous resection of all disease. Staged resections should be considered for patients in whom the volume of the future liver remnant is anticipated to be marginal or inadequate, who have significant medical comorbid condition(s), or in whom extensive resections are required for the primary cancer and/or CRLM. Priority for liver-first or primary-first resection should depend on primary tumour-related symptoms or concern for the progression of marginally resectable CRLM during treatment of the primary disease. Chemotherapy delivered by hepatic arterial infusion represents a valid option in patients with liver-only disease, although it is best delivered in experienced centres. Ablation strategies are not recommended as first-line treatments for resectable CRLM alone or in combination with resection because of high local failure rates and limitations related to tumour size, multiplicity and intrahepatic location.

    Full Text Available To develop prognostic nomograms for predicting outcomes in patients with locally advanced rectal cancers who do not receive preoperative treatment.A total of 883 patients with stage II-III rectal cancers were retrospectively collected from a single institution. Survival analyses were performed to assess each variable for overall survival (OS, local recurrence (LR and distant metastases (DM. Cox models were performed to develop a predictive model for each endpoint. The performance of model prediction was validated by cross validation and on an independent group of patients.The 5-year LR, DM and OS rates were 22.3%, 32.7% and 63.8%, respectively. Two prognostic nomograms were successfully developed to predict 5-year OS and DM-free survival rates, with c-index of 0.70 (95% CI = [0.66, 0.73] and 0.68 (95% CI = [0.64, 0.72] on the original dataset, and 0.76 (95% CI = [0.67, 0.86] and 0.73 (95% CI = [0.63, 0.83] on the validation dataset, respectively. Factors in our models included age, gender, carcinoembryonic antigen value, tumor location, T stage, N stage, metastatic lymph nodes ratio, adjuvant chemotherapy and chemoradiotherapy. Predicted by our nomogram, substantial variability in terms of 5-year OS and DM-free survival was observed within each TNM stage category.The prognostic nomograms integrated demographic and clinicopathological factors to account for tumor and patient heterogeneity, and thereby provided a more individualized outcome prognostication. Our individualized prediction nomograms could help patients with preoperatively under-staged rectal cancer about their postoperative treatment strategies and follow-up protocols.

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

  7. Importance of Extracranial Disease Status and Tumor Subtype for Patients Undergoing Radiosurgery for Breast Cancer Brain Metastases

    International Nuclear Information System (INIS)

    Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases. Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) ≤ 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS ≤ 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes. Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS.

    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.

  10. Incremental value of metabolic radiotherapy of bone metastases with 153Sm-EDTMP in prostate cancer. About 67 cases

    International Nuclear Information System (INIS)

    Full text of publication follows. Introduction: painful bone metastases are common in advanced prostate cancer. Samarium-153-ethylenediaminetetra-methylenephosphonic acid (153Sm-EDTMP; Quadramet) is a beta-particles emitter that concentrates in the areas of enhanced osteoblastic activity and used for palliate pain from bone metastases. Our purpose is to evaluate the incremental value of the 153Sm-EDTMP, in patients affected of cancer of the prostate with painful bony metastasis. Methods: 67 patients with metastatic prostate cancer received a single bolus infusion of 153Sm (37 MBq/kg). All patients had painful bone metastases to more than one anatomical region. Bone specific pain, analgesic score, and blood count were evaluated before and after treatment with a receding of 38 months. Results: we observed a positive answer in 85% of the cases; this answer was complete in 35% of the cases. The results gotten after multiple administrations show that the cures could be repeated with results comparable to those of the first cure. The therapeutic efficiency is at least equivalent to those of the other therapeutic means, with nearly non-existent secondary effects. The only toxicity is of hematological order; it is the most often moderate and reversible with a complete recuperation at the end of 8 weeks. Besides, the effect on the pain came with an improvement of the quality of life of the patients treaties. Conclusion: due to its half-life of 46 hours and its beta emissions, a high dose rate of 153Sm can be delivered to regions adjacent to enhanced osteoblastic activity over a short period of time with little residual long term activity being left in the bone marrow. Its administration to patients with prostate cancer suffering from painful bone metastases that enhance on bone scans, offered clinical relevant pain relief with tolerable hematological toxicity and then enjoy a better quality of life.

    Full Text Available The analysis of the performed study has established that zoledronic acid is an effective agent in multimodality therapy for locally advanced prostate cancer (PC and allows long-term stabilization of bone tissue. In addition, there is evidence for the efficacy of zoledronic acid in preventing bone metastases (BM and increasing the time to the first BM. The currently accumulated experience with zoledronic acid used in PC permits one to consider its use as standard concomitant therapy.

    Bone is the most common site of prostate cancer (PCa) progression to a therapy-resistant, lethal phenotype. We found that blockade of fibroblast growth factor receptors (FGFRs) with the receptor tyrosine kinase inhibitor dovitinib has clinical activity in a subset of men with castration-resistant PCa and bone metastases. Our integrated analyses suggest that FGF signaling mediates a positive feedback loop between PCa cells and bone cells and that blockade of FGFR1 in osteoblasts partially medi...

  15. SPECT/CT fusion imaging for differential diagnosis of bone solitary metastases in patients with lung cancer

    International Nuclear Information System (INIS)

    Background: Making an accurate diagnosis of bone metastasis earlier is very important for lung cancer clinical stage and making treatment plans. SPECT/CT fusion imaging provides more information than SPECT in diagnosing bone metastases from benign lesions of the solitary abnormal radioactive nuclide distribution in patients with lung cancer. Purpose: We want to investigate the value of SPECT/CT fusion imaging in identifying solitary bone metastases in patients with lung cancer. Methods: 196 patients with lung cancer, whose bone scintigraphy demonstrated solitary abnormal radioactive nuclide distribution, were selected. SPECT/CT was employed for those lesions. SPECT and SPECT/CT bone images were analyzed by two seasoned nuclear medicine physicians separately. Each lesion was diagnosed with metastasis and benign lesion, The diagnosed results were compared with the final diagnosis. Results: 196 patients with lung cancer had 196 lesions, 112 bone metastatic lesions were proved to be bone metastatic criterion, 89 metastatic lesions were found by SPECT, and 106 metastatic lesions were found by SPECT/CT. The sensitivity, specificity and accuracy of SPECT/CT and SPECT in the diagnosis of bone metastasis were 94.6% (106/112), 92.9% (78/84), 93.9% (184/196); 79.5% (89/112), 78.6% (78/84) and 79.1% (155/196), respectively. The sensitivity, specificity and accuracy of SPECT/CT were higher than those of SPECT (χ2=11.25, P<0.05; χ2=7.00, P<0.05; χ2=18.35, P<0.05). Conclusions: SPECT/CT fusion imaging provided more information than SPECT imaging in distinguishing metastases from benign lesions of the solitary abnormal radioactive nuclide distribution in patients with lung cancer and improved the accuracy of the diagnosis of solitary bone metastasis of lung cancer.

    2016-04-01

    The development of trastuzumab and other targeted systemic therapies has transformed the management of HER-2 positive breast cancers. However, as patients live longer and systemic therapies may not cross the blood brain barrier a rising number of patients are developing leptomeningeal metastases and brain metastases as a sanctuary site of disease. Intrathecal trastuzumab has been reported to treat these. We describe a breast cancer patient with HER-2 positive leptomeningeal disease in the spinal cord successfully treated with intrathecal trastuzumab and methotrexate, alongside systemic anti-HER-2 therapy and radiotherapy. We also review the literature to date on the efficacy and safety of intrathecal trastuzumab, and recent evidence suggesting that intrathecal trastuzumab passes via the blood brain barrier into the serum to achieve intravenous concentrations similar to that seen with systemic therapy alone. Overall, intrathecal trastuzumab appears to be a safe and often effective treatment for leptomeningeal metastases in HER-2 positive breast cancer. Ongoing phase I and II studies are required to determine optimum dosing schedules, validate CSF and CSF-to-serum pharmacokinetics, determine efficacy, and to assess the added benefits or disadvantages of prior radiotherapy and concomitant systemic therapy.

  18. Evaluation of superficial hyperthermia and radiotherapy combination as a palliative treatment of skin and lymphatic nodes cancer metastases

    International Nuclear Information System (INIS)

    Full text: Evaluation of superficial hyperthermia and radiotherapy combination effectiveness and toxicity as a palliative treatment of skin and lymphatic nodes cancer metastases. Mean tumor diameter before the treatment was 4.7 cm and varied from 0.5 to 15 cm. Tumor diameter decreased to 3.2 cm within two weeks. During following two controls mean tumor diameters were 3.6 and 3.8 cm. Next, majority of tumors started to progress and 7.5 months after treatment mean diameter was 5.4 cm. During two next examinations mean tumor diameter were 6.0 and 5.7 cm respectively. Mean percentage regression was biggest two weeks after treatment completion (28 %). This values were 20 % and 23 % during two following controls. Next, the progression started. The correlation analysis showed statistically significant dependency between total radiation dose and regression after 1.5 months after the treatment (p=0.04, R=0.4). No significant dependencies were found between tumor regressions dependently on pathological, clinical diagnoses and metastases location. Obtained results allow to form conclusion that combination of hyperthermia and radiotherapy could be as useful as a palliative treatment modality for skin and nodal cancer metastases, but final evaluation of such treatment is very difficult because of its local character and systemic character of advanced cancers. Eventual gain from this combined treatment should be confirmed in relation to radiotherapy alone, probably for each techniques performed in particular centers. (author)

  19. The expression of Dicer and Drosha in matched normal tissues, tumours and lymph node metastases in triple negative breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is the most common malignancy in women world-wide. Triple negative breast cancer (TNBC) is a highly aggressive subtype that lacks expression of hormone receptors for estrogen, progesterone and human epidermal growth factor 2; and is associated with a high propensity for metastatic spread. Several studies have identified critical roles for microRNAs in breast cancer, but the role of two critical enzymes involved in microRNA biogenesis, Dicer and Drosha, is not well understood, particularly with respect to metastatic progression in this subtype. We examined the expression of Dicer and Drosha in a series of invasive 35 TNBCs with matched normal adjacent tissues (n = 18) and lymph node metastases (n = 15) using semi-quantitative real time RT-PCR. The relationship of their expression with clinical features including age at diagnosis, lymph node positivity and tumour size was analysed. We report that Dicer was significantly decreased while Drosha was significantly increased in tumours when compared to normal adjacent tissues. While there was no difference in Drosha expression in lymph node metastases when compared to the primary tumour, Dicer was significantly increased. There was no correlation between the expression of either Dicer or Drosha to age at diagnosis, lymph node positivity and tumour size. In conclusion, Dicer and Drosha are dysregulated in TNBC and matched lymph node metastases however, the clinical relevance of this is still not known. The altered expression of Dicer and Drosha may serve as markers for disrupted miRNA biogenesis in TNBC

    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.

    Electrochemotherapy (ECT) has emerged among European centers as an innovative locoregional treatment for patients with unresectable skin cancers or superficial metastases from any histotype. The combined administration of a cytotoxic agent (bleomycin or cisplatin) with properly tuned electric pulses results in locally-enhanced drug delivery (reversible electroporation) into malignant cells and sustained tumor response. Reversible electroporation represents the basis of ECT and allows the potentiation of two low permeant cytotoxic agents such as bleomycin (~8000 fold) and cisplatin (~80 fold). The procedure was standardized in 2006 - thanks to a European project - and shortly after introduced in the clinical practice. In recent years, experience with ECT has accumulated mainly in melanoma and breast cancer patients with cutaneous metastases, in whom complete response rates of 20-50% and 40-75% have been reported, respectively, depending on tumor size. Currently, this therapy is being investigated in deep-seated (i.e. bone, soft tissue) metastases and visceral malignancies (i.e. locally advanced pancreatic cancer), with encouraging results.

    Metastatic growth and invasion by colon cancer cells in the liver requires the ability of the cancer cells to interact with the new tissue environment. Plasmin(ogen) is activated on cell surfaces by urokinase-type PA (uPA), and is regulated by uPAR and plasminogen activator inhibitor-1 (PAI-1......). To compare the expression patterns of uPA, uPAR and PAI-1 in colon cancer with that in their liver metastases, we analysed matched samples from 14 patients. In all 14 primary colon cancers, we found upregulation of uPAR, uPA mRNA and PAI-1 in primarily stromal cells at the invasive front. In 5 of the 14......, whereas 8 of the remaining 9 showed direct contact between the cancer cells and the liver parenchyma. We conclude that there are 2 distinct patterns of expression of uPAR, uPA and PAI-1 in colon cancer liver metastases and that these correlate closely with 2 morphological growth patterns. These findings...

    For lung cancer patients with epidermal growth factor receptor (EGFR) mutations, the advent of EGFR tyrosine kinase inhibitors (TKIs) has prolonged survival rates. Even though disease sites have been well controlled by EGFR-TKIs, some patients develop carcinomatous meningitis, which reduces their quality of life drastically. Although multidisciplinary approaches have improved patient survival and quality of life, the outcomes are not yet satisfactory. We report the case of a 54-year-old Japanese woman diagnosed with leptomeningeal metastases (LM) from a lung adenocarcinoma harboring an EGFR exon 21 L858R point mutation. She was treated with gefitinib for 2 months, and symptoms of LM emerged during the treatment period. Although the treatment was switched to erlotinib, disturbance of consciousness worsened because of progressive hydrocephalus. Because all extracranial lesions remained responsive to treatment, and the exon 20 T790M point mutation was not detected in cerebrospinal fluid, we placed a ventriculoperitoneal shunt. The patient’s disturbed consciousness improved dramatically after the shunt was placed; however, the optic and auditory nerve impairments due to direct invasion of LM lesions into nerve canals persisted. Administration of bevacizumab subsequent to whole-brain radiotherapy reduced the cranial nerve impairment, and the patient survived for 10 months. In conclusion, a combination of erlotinib and ventriculoperitoneal shunt was effective for hydrocephalus, and the immediate administration of additional therapies, including bevacizumab and radiation therapy, was useful in a patient suffering from LM.

    Abstract Background: Brain metastases (BMs) are a common and serious complication of non-small cell lung cancer (NSCLC). Whole-brain radiotherapy (WBRT), surgery, and molecular targeted therapy are usually used to treat NSCLC with BM. Chemotherapeutic options for BM are limited by tumor resistance, ineffective agents, and the blood–brain barrier. Pemetrexed/cisplatin is the preferred chemotherapy in nonsquamous NSCLC, but the efficacy of this treatment for nonsquamous NSCLC with BM is uncertain. Methods: We present a case of nonsquamous NSCLC with asymptomatic BM presenting with irritating cough and right shoulder back pain (unknown sensitizing epidermal growth factor receptor mutations or anaplastic lymphoma kinase). Results: He benefited from administration of first-line chemotherapy of pemetrexed/cisplatin. Partial remission was achieved in the primary lesion of the lungs and BM lesion. He was further given 3 cycles of pemetrexed monotherapy and WBRT. Complete remission was further achieved in BM lesion. Conclusion: The findings of clinical trials and theoretical studies about the current pemetrexed/cisplatin in the treatment of nonsquamous NSCLC with BM are also summarized to provide a reference for the application of pemetrexed/cisplatin in nonsquamous NSCLC with BM. Whether or not pemetrexed/cisplatin is definitely effective in nonsquamous NSCLC with BM must be proven by subsequent phase III clinical trials. PMID:27512852

  6. Peri-operative chemotherapy in the management of resectable colorectal cancer pulmonary metastases

    International Nuclear Information System (INIS)

    Surgery is often advocated in patients with resectable pulmonary metastases from colorectal cancer (CRC). Our study aims to evaluate peri-operative chemotherapy in patients with metastastic CRC undergoing pulmonary metastasectomy. Patients treated for CRC who underwent pulmonary metastasectomy by a single surgeon were identified. Outcome measures included survival, peri-operative complications, radiological and histological evidence of chemotherapy-induced lung toxicities. Between 1997 and 2009, 51 eligible patients were identified undergoing a total of 72 pulmonary resections. Thirty-eight patients received peri-operative chemotherapy, of whom 9 received an additional biological agent. Five-year overall survival rate was 72% in the whole cohort - 74% and 68% in those who received peri-operative chemotherapy (CS) and those who underwent surgery alone (S) respectively. Five-year relapse free survival rate was 31% in the whole cohort - 38% and ≤18% in CS and S groups respectively. Only 8% had disease progression during neoadjuvant chemotherapy. There were no post-operative deaths. Surgical complications occurred in only 4% of patients who received pre-operative chemotherapy. There was neither radiological nor histological evidence of lung toxicity in resected surgical specimens. Peri-operative chemotherapy can be safely delivered to CRC patients undergoing pulmonary metastasectomy. Survival in this selected group of patients was favourable

  8. Use of Yttrium-90 Microspheres in the Treatment of Unresectable Hepatic Metastases From Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: Therapy for patients with unresectable liver metastases from breast cancer that were refractory to multiple treatment regimens was performed using radioactive microspheres. High doses of radiation were delivered to tumors from these permanently implanted yttrium-90 (90Y) microspheres, delivered through the hepatic arterial vessels. Methods and Materials: Women from three institutions were selected for treatment, after screening that demonstrated vascular access to all tumors and after imaging confirmed that microspheres would be implanted only in the liver tumors. All patients were followed with laboratory and imaging studies at regular intervals until death. Toxicities, both acute and late were recorded, and actuarial survival determined. Results: A total of 44 women were treated from April 2002 to April 2005. Median follow-up of these women was 14 months (1-42 months). No treatment-related procedure deaths or radiation related veno-occlusive liver failures were found. Computed tomographic imaging partial response was 47% and positron emission tomographic response 95%. Conclusion: In this group of heavily pretreated patients, radioactive microspheres produced an encouraging median survival, with acceptable toxicity and a significant objective response rate, suggesting that further investigation of this approach is warranted

  9. Regression of brain metastases of non-small cell lung cancer after radiotherapy

    International Nuclear Information System (INIS)

    Regression of metastatic brain tumors after irradiation was studied. Twenty-three patients with 80 metastatic tumors were irradiated by conventional fractionation (8-9 Gy/5 Fx/week, 17 patients with 54 tumors) or a hypofractionation (10 Gy/1 Fx/week, 6 patients with 26 tumors). TDF (Time Dose Fractionation Factor) calculated from radiation doses was between 60 and 106 in the former fractionation, and 80 and 89 in the latter. The tumor regression curves were obtained from the volume of each tumor measured on contrast enhanced CT. The tumor regression correlated well with the initial tumor volume. Smaller volume tumors showed greater regression. This trend was more remarkable in patients treated by hypofractionation than in those by conventional fractionation 4 and 6 weeks after starting the radiotherapy. Response rates (PR+CR) after 4, 6, 12 and 26 weeks were 56% (45/80), 83% (40/48), 89% (24/27) and 90% (17/19). Complete response was observed in 6%, 15%, 59% and 74%, respectively. Eighty seven percent (14/16) of the tumors smaller than 103 mm3 showed CR after 12 weeks. All the 14 CR tumors had been treated by the conventional fractionation. Based on our results the brain metastases of non-small cell lung cancer were controled well by radiotherapy with doses below the brain tolerance dose level, especially in tumors smaller than 103 mm3.

Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases is hitherto controversial. Patients and methods: We retrospectively analyzed the cases of NSCLC patients with brain metastases who underwent neurosurgical resection at the Sun Yat-sen University Cancer Center, and assessed the efficacy of surgical resection and the necessity of aggressive treatment for primary NSCLC in synchronous brain metastases patients. Results: A total of 62 patients, including 47 men and 15 women, with brain metastases from NSCLC were enrolled in the study. The median age at the time of craniotomy was 54 years (range 29–76 years. At the final follow-up evaluation, 50 patients had died. The median OS time was 15.1 months, and the survival rates were 70% and 37% at 1 and 2 years, respectively. The median OS

    Radioactive iodine (RAI) remains one of the primary treatment options for metastatic, follicular cell derived thyroid cancers. The aim of this study was to determine the likelihood that metastatic lesions arising from one of the aggressive thyroid cancer histologies [tall cell variant of papillary thyroid carcinoma (TCV-PTC), poorly differentiated thyroid carcinoma (PDTC) and Hurthle cell carcinoma (HCC)] would demonstrate sufficient RAI avidity for visualization on RAI scanning and therefore could potentially benefit from RAI therapy. The study shows that in patients selected for RAI scanning or therapy at our center, RAI avid lesions can be identified in more than two thirds of the patients with distant metastases arising in the setting of C-PTC, WD-FTC, FV-PTC, TCV-PTC, or PDTC primary tumors. While RAI avidity on a post-therapy scan does not always correlate with clinically significant tumor killing activity, it is likely that some of these patients with RAI avid metastatic disease did obtain a clinical benefit

    Full Text Available Objective: Cancer represents the second cause of mortality in the world. Saffron as a medicinal plant is known for its anti-cancer and anti-depressant properties. In this randomized double blind clinical trial, the effects of saffron on response to treatment in patients suffering from liver metastasis were evaluated. Materials and Methods: Thirteen patients suffering from liver metastases who referred to Ghaem and Imam Reza hospital, Mashhad, Iran were included in this study and then divided into two different groups. Both groups received chemotherapy regimen. Patients in group one were treated with saffron capsule (50 mg, twice daily during chemotherapy periods whereas patients in group two received placebo. A sum of the longest diameter were calculated and compared for all lesions in IV contrast CT scan before and after the treatment. Results: from 13 patients included in this study, six patients quit and seven continued until the end. In saffron-treated group, two patients showed partial and complete response (50% whereas in placebo group, no response was seen. Also, two deaths in placebo and one in saffron group occurred. Conclusion: This research suggests that saffron might be useful in patients suffering from liver metastasis. However, further investigations with larger sample size are required.

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

    The causality between the metastatic potential, mismatch repair status (MMR) and survival in colorectal cancer (CRC) is complex. This study aimed to investigate the impact of MMR in CRC on the occurrence of synchronous metastases (SCCM) and survival in patients with SCCM on a national basis. A nationwide cohort study of 6,692 patients diagnosed with CRC between 2010 and 2012 was conducted. Data were prospectively entered into the Danish Colorectal Cancer Group's database and merged with data from the Danish Pathology Registry and the National Patient Registry. Multivariable and multinomial logistic- and Cox-regression and proportional excess hazards analyses were used for confounder adjustment and to adjust for the general population mortality. In total, 983 of 6,692 patients (14.7%) had dMMR and 935 (14.0%) had SCCM. dMMR was associated with a decreased risk of SCCM, adjusted Odds Ratio (aOR) = 0.54 (95% confidence interval (CI):0.40-0.70, p Hazard Ratio (aHR) = 0.76, 95% CI: 0.54-1.06, p = 0.101; Proportional excess hazards: aHR = 0.73, 95% CI: 0.50-1.07, p = 0.111) when adjusting for other prognostic factors. The metastatic pattern varied according to MMR status. MMR had no impact on survival in patients with UICC Stage IV CRC. These findings may be important for the understanding of the metastatic processes and thus for optimizing staging and treatment in CRC patients. PMID:25921209

  15. Lactate stimulates migration of human cancer cells: possible consequences for the development of metastases

    International Nuclear Information System (INIS)

    A high lactate production is a common feature of the majority of malignant tumors. In several independent series of clinical studies we could show that a high lactate content in primary human carcinomas was correlated with a higher incidence of metastases and a reduced patient survival, compared to tumors with a lower lactate content. Since one of the early events in metastasis is the active movement of cancer cells out of the primary tumor site, we have investigated the effect of exogenous lactate on the migratory activity of human cancer cells in vitro. - A 48 well micro chemotaxis chamber was used to quantify the migration of SQ20B and PCI13 cells which were derived from human head and neck squamous cell carcinomas. The chamber consists of bottom and a top Lucite slide, separated by a gelatin covered polycarbonate membrane with pores of 8 μm, where cells eventually migrate through. - In summary, there was a time and concentration dependent unidirectional enhancement of cell migration. For example, cells were incubated in growth medium supplemented with 20 mM L-lactate. On the average, the rate of cell migration was significantly enhanced (p < 0.001) to 139 % for SQ20 and 136 % for PCI cells, compared to untreated control cells (100 %). No effects on cell migration were detected for culture media containing 20 mM D-lactate or 20 mM sodium chloride. These results suggest that an elevated lactate production may not only be an accompanying phenomenon of malignant transformation, but may also play an active part in tumor progression by enhancing cell migration and dissemination of potentially metastatic cells from primary lesions

    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

    A new type of signaling network element, called cancer signaling bridges (CSB), has been shown to have the potential for systematic and fast-tracked drug repositioning. On the basis of CSBs, we developed a computational model to derive specific downstream signaling pathways that reveal previously unknown target-disease connections and new mechanisms for specific cancer subtypes. The model enables us to reposition drugs based on available patient gene expression data. We applied this model to ...

  18. Radiation therapy for epithelial ovarian cancer brain metastases: clinical outcomes and predictors of survival

    International Nuclear Information System (INIS)

    Brain metastases (BM) and leptomeningeal disease (LMD) are uncommon in epithelial ovarian cancer (EOC). We investigate the outcomes of modern radiation therapy (RT) as a primary treatment modality in patients with EOC BM and LMD. We evaluated 60 patients with EOC treated at our institution from 1996 to 2010 who developed BM. All information was obtained from chart review. At EOC diagnosis, median age was 56.1 years and 88% of patients were stage III-IV. At time of BM diagnosis, 46.7% of patients had 1 BM, 16.7% had two to three, 26.7% had four or more, and 10% had LMD. Median follow-up after BM was 9.3 months (range, 0.3-82.3). All patients received RT, and 37% had surgical resection. LMD occurred in the primary or recurrent setting in 12 patients (20%), 9 of whom received RT. Median overall survival (OS) after BM was 9.7 months for all patients (95% CI 5.9–13.5), and 16.1 months (95% CI 3.8-28.3) in patients with one BM. On multivariate analysis, Karnofsky performance status less than 70 (hazard ratio [HR] 2.86, p = 0.018), four or more BM (HR 3.18, p = 0.05), LMD (HR 8.22, p = 0.013), and uncontrolled primary tumor (HR 2.84, p = 0.008) were significantly associated with inferior OS. Use of surgery was not significant (p = 0.31). Median central nervous system freedom from progression (CNS-FFP) in 47 patients with follow-up was 18.5 months (95% CI, 9.3–27.9). Only four or more BM (HR 2.56, p = 0.04) was significantly associated with poorer CNS-FFP. Based on our results, RT appears to be an effective treatment modality for brain metastases from EOC and should be routinely offered. Karnofsky performance status less than 70, four or more BM, LMD, and uncontrolled primary tumor predict for worse survival after RT for EOC BM. Whether RT is superior to surgery or chemotherapy for EOC BM remains to be seen in a larger cohort

    Full Text Available Brain metastases are the most common cancerous neoplasm in the brain. The treatment of these lesions is challenging and often includes a multimodality management approach with whole-brain radiation therapy, stereotactic radiosurgery, and neurosurgery options. Although advances in biomedical imaging technologies and the treatment of extracranial cancer have led to the overall increase in the survival of brain metastases patients, the finding that select patients survive several years remains puzzling. For this reason, we present the case of a 70-year-old patient who was diagnosed with multiple brain metastases from small-cell lung cancer five years ago and is currently alive following treatment with chemotherapy for the primary cancer and whole-brain radiation therapy and Gamma Knife radiosurgery on four separate occasions for the neurological cancer. Since the diagnosis of brain metastases five years ago, the patient’s primary cancer has remained controlled. Furthermore, multiple repeat GKRS procedures provided this patient with high levels of local tumor control, which in combination with a stable primary cancer led to an extended period of survival and a highly functional life. Further analysis and clinical research will be valuable in assessing the durability of multiple GKRS for brain metastases patients who experience long-term survival.

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

    Each year in the UK, between 12-14,000 people develop liver metastases from colorectal cancer. These metastases will contribute to the death of the patient in about 80% of cases. Treatments aimed at these tumours are best administered when the tumour is small. Current investigative methods allow tumours as small as 0.5 mm to be detected, and should be offered to all colorectal cancer patients at risk of developing liver metastases.

  2. Use of Stereotactic Radiosurgery for Brain Metastases From Non-Small Cell Lung Cancer in the United States

    International Nuclear Information System (INIS)

    Purpose: The indications for treatment of brain metastases from non-small cell lung cancer (NSCLC) with stereotactic radiosurgery (SRS) remain controversial. We studied patterns, predictors, and cost of SRS use in elderly patients with NSCLC. Methods and Materials: Using the Surveillance, Epidemiology, and End Results-Medicare (SEER-Medicare) database, we identified patients with NSCLC who were diagnosed with brain metastases between 2000 and 2007. Our cohort included patients treated with radiation therapy and not surgical resection as initial treatment for brain metastases. Results: We identified 7684 patients treated with radiation therapy within 2 months after brain metastases diagnosis, of whom 469 (6.1%) cases had billing codes for SRS. Annual SRS use increased from 3.0% in 2000 to 8.2% in 2005 and varied from 3.4% to 12.5% by specific SEER registry site. After controlling for clinical and sociodemographic characteristics, we found SRS use was significantly associated with increasing year of diagnosis, specific SEER registry, higher socioeconomic status, admission to a teaching hospital, no history of participation in low-income state buy-in programs (a proxy for Medicaid eligibility), no extracranial metastases, and longer intervals from NSCLC diagnosis. The average cost per patient associated with radiation therapy was 2.19 times greater for those who received SRS than for those who did not. Conclusions: The use of SRS in patients with metastatic NSCLC increased almost 3-fold from 2000 to 2005. In addition, we found significant variations in SRS use across SEER registries and socioeconomic quartiles. National practice patterns in this study suggested both a lack of consensus and an overall limited use of the approach among elderly patients before 2008.

  3. Radioimmunodetection of hepatic metastases from human colon cancer in nude mice with a gamma-detecting probe

    International Nuclear Information System (INIS)

    The utility of a gamma detecting probe (GDP) in the detection of experimental hepatic metastases in nude mice using radiolabeled monoclonal antibody (mAb) was assessed. Twelve mice with established hepatic metastases from the HT-29 LMM cell line, 5 mice with s.c. tumors in the left flank and 6 non-tumor-bearing control mice were given i.v. injections of 40 microCi/4 micrograms of 125I-labeled mAb HT-29-15. Six tumor-bearing mice were given i.v. injections of an isotype-matched control mAb (BL-3). Using the GDP, measurements were obtained daily over the region of the heart, the region of the liver (i.e., the right flank), and the s.c. tumor when applicable. Intraoperative measurements were obtained at laparotomy on days 5 and 7. Subsequently, the metastases, normal liver, and blood were resected and the radioactivity/g tissue was measured in a gamma well counter. External right flank/heart ratios were significantly higher in the tumor-bearing group than in controls. External measurements allowed detection of small tumors weighing only 161 ± 87 (SD) mg and occupying 11.5 ± 4% of the entire liver weight. Metastases counted intraoperatively with the GDP measured 1 to 7 mm in greatest diameter. The mean metastasis/heart GDP ratio was 1.7 ± 0.4:1. Tumors weighing as little as 51 ± 42 mg could be identified. These experimental results confirm the usefulness of the GDP for the detection of small hepatic metastases from colon cancer and illustrate important features of probe measurement of radiolabeled mAb uptake

  4. Upfront systemic chemotherapy and preoperative short-course radiotherapy with delayed surgery for locally advanced rectal cancer with distant metastases

    International Nuclear Information System (INIS)

    Choosing the most effective approach for treating rectal cancer with mesorectal fascia (MRF) involvement or closeness and synchronous distant metastases is a current clinical challenge. The aim of this retrospective study was to determine if upfront systemic chemotherapy and short-course radiotherapy (RT) with delayed surgery enables R0 resection. Between March 2009 and October 2009, six patients were selected for upfront chemotherapy and short-course RT (5 × 5 Gy) with delayed surgery. The patients had locally advanced primary tumors with MRF involvement or closeness, as well as synchronous and potentially resectable distant metastases. Chemotherapy was administered to five patients between the end of the RT and surgery. All patients underwent total mesorectal excision (TME). The median patient age was 54 years (range 39-63). All primary and metastatic lesions were resected simultaneously. The median duration between short-course RT and surgery was 13 weeks (range, 7-18). R0 resection of rectal lesions was achieved in 5 patients. One patient, who had a very low-lying tumor, had an R1 resection. The median follow-up duration for all patients was 16.7 months (range, 15.5-23.5). One patient developed liver metastasis at 15.7 months. There have been no local recurrences or deaths. Upfront chemotherapy and short course RT with delayed surgery is a valuable alternative treatment approach for patients with MRF involvement or closeness of rectal cancer with distant metastases

    Full Text Available Abstract A 31-year-old man with sigmoid colon cancer with concomitant simultaneous multiple liver metastases had received FOLFIRI (leucovorin, fluorouracil and irinotecan and FOLFOX6 (leucovorin, fluorouracil and oxaliplatin after an ordinary sigmoidectomy. However, his serum carcinoembryonic antigen (CEA level increased rapidly during the fifteen months after the operation while he was on FOLFOX6. Abdominal computed tomography revealed expanding multiple liver tumors. As the third line chemotherapy, a combination therapy of cetuximab with irinotecan was given, which markedly reduced his levels of serum CEA, and the size and number of liver tumors. He underwent lateral segmentectomy of the liver and microwave coagulation of the liver metastases in the remnant liver. Thereafter, a good quality of life with tumor dormancy was obtained for 6 months. However, his serum CEA started to rise again in the absence of liver tumors. Therefore, FOLFOX6 with bevacizumab was chosen as the fourth line chemotherapy, and the serum CEA was reduced with tumor dormancy. A good quality of life was obtained again at 3 years after the first surgery. This report indicates the effectiveness of sandwiched liver surgery with the molecular targeting drugs cetuximab and bevacizumab on multiple liver metastases of colon cancer, and suggests the possibility of a regimen consisting of bevacizumab following cetuximab.

  6. Evaluation of 131I treatment efficacy and prognostication for bone metastases from differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of 131I treatment for bone metastases from DTC and analyze the survival rates after 131I treatment and prognostic factors. Methods: One hundred and six DTC patients with bone metastases treated by 131I during January 1991 and January 2009 were retrospectively analyzed. Treatment efficacy was assessed based on serum Tg change, bone pain palliation and changes on medical imaging. Univariate analysis was performed for defining the factors affecting 131I treatment efficacy. Survival curves were estimated using the life table method. Survival analysis was performed using Kaplan-Meier method. Results: Serum Tg decreased dramatically in 37/106 (34.9%) patients treated with 131I. Thirty-nine of 61 patients (63.9%) with bone pain had pain relief. Age, tumor subtype and presence of non-osseous distant metastases were significant factors affecting 131I treatment efficacy based on serum Tg change (χ2=6.443, 11.455, 6.756, all P2=0, 0, 0.060, all P>0.05). There were no imaging changes of bone metastases in 77.4% of patients after 131I treatment. The overall 5-year and 10-year survival rates from initial diagnosis of bone metastases was 86.47% and 57.90%, respectively. Univariate analysis showed that number of metastases, presence of non-osseous distant metastases and pre-131I treatment surgery were significant factors for survival (Log-rank values were 4.05, 5.98, 4.22, all P131I treatment for bone metastases from DTC is effective for lowering serum Tg and palliation of bone pain. Single metastasis, absence of non-osseous distant metastases and pre-131I therapy surgery are favorable predictors of prognosis. (authors)

  7. Stereotactic, single-dose irradiation of stage I non-small cell lung cancer and lung metastases

    International Nuclear Information System (INIS)

    We prospectively reviewed response rates, local control, and side effects after non-fractionated stereotactic high single-dose body radiation therapy for lung tumors. Fifty-eight patients underwent radiosurgery involving single-dose irradiation. With 25 patients, 31 metastases in the lungs were irradiated; with each of 33 patients, stage I non-small cell lung cancer (NSCLC) was subject to irradiation. The standard dose prescribed to the isocenter was 30 Gy with an axial safety margin of 10 mm and a longitudinal safety margin of 15 mm. The planning target volume (PTV) was defined using three CT scans with reference to the phases of respiration so that the movement span of the clinical target volume (CTV) was enclosed. The volume of the metastases (CTV) varied from 2.8 to 55.8 cm3 (median: 6.0 cm3) and the PTV varied from 12.2 to 184.0 cm3 (median: 45.0 cm3). The metastases ranged from 0.7 to 4.5 cm in largest diameter. The volume of the bronchial carcinomas varied from 4.2 to 125.4 cm3(median: 17.5 cm3) and the PTV from 15.6 to 387.3 cm3 (median: 99.8 cm3). The bronchial carcinomas ranged from 1.7 to 10 cm in largest diameter. Follow-up periods varied from 6.8 to 63 months (median: 22 months for metastases and 18 months for NSCLC). Local control was achieved with 94% of NSCLC and 87% of metastases. No serious symptomatic side effects were observed. According to the Kaplan-Meier method the overall survival probability rates of patients with lung metastases were as follows: 1 year: 97%, 2 years: 73%, 3 years: 42%, 4 years: 42%, 5 years: 42% (median survival: 26 months); of those with NSCLC: 1 year: 83%, 2 years: 63%, 3 years: 53%, 4 years: 39%: (median survival: 20.4 months). Non-fractionated single-dose irradiation of metastases in the lungs or of small, peripheral bronchial carcinomas is an effective and safe form of local treatment and might become a viable alternative to invasive techniques

    Breast cancer metastasizing to the pleura, pericardium and leptomeninges, but not to other sites, is rare. Although malignant pericardial and pleural effusions are common complications during the course of malignancies, they are rarely the initial manifestations of malignant disease, particularly pericardial effusion with cardiac tamponade. This report describes a case of breast carcinoma in a 44-year-old woman who initially presented with malignant pleural effusion and pericardial tamponade and suffered from meningeal metastases after 4.5 months. Unfortunately, the patient succumbed to pericardial tamponade 7 months later. There was no metastasis identified in other organs during the course of the disease. To the best of our knowledge, no similar case has been reported in the literature to date. PMID:27123295

  9. Whole-body MRI (WB-MRI) versus axial skeleton MRI (AS-MRI) to detect and measure bone metastases in prostate cancer (PCa)

    International Nuclear Information System (INIS)

    To compare whole-body MRI (WB-MRI) and axial skeleton MRI (AS-MRI) in detecting and measuring bone metastases in patients with prostate cancer (PCa). WB-MRI and AS-MRI examinations were performed in 60 patients with PCa at high risk of metastases. Two radiologists separately categorised the AS-MRI and WB-MRI as negative or positive for metastases, and measured focal metastases using the ''Response evaluation criteria in solid tumours'' (RECIST) criteria transposed to bone. One radiologist reviewed all examinations 2 months later. Inter- and intraobserver agreements in establishing the presence/absence of metastases were calculated. Bland-Altman plots were used to assess measurement agreement between AS-MRI and WB-MRI. Strong to perfect inter- and intraobserver agreements were found between AS-MRI and WB-MRI in defining the presence/absence of bone metastases. There were no patients with isolated ''peripheral'' metastases at WB-MRI, missed at AS-MRI. There was no difference in lesion count between the two radiologists. AS-MRI and WB-MRI provided statistically equivalent RECIST values for one radiologist and slightly lower values at AS-MRI for the other. In our series of PCa patients, AS-MRI and WB-MRI were equivalent in determining the presence/absence of bone metastases and provided similar evaluation of the metastatic burden. (orig.)

  11. 32-Phosphorus for bone pain palliation due to bone metastases, its safety and efficacy in patients with advanced cancer

    International Nuclear Information System (INIS)

    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.

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

    Approximately half of all patients with non-small cell lung cancer (NSCLC) develop central nervous system metastases during the course of their disease which indicate poor prognosis. A part of NSCLC patients demonstrates activating epidermal growth factor receptor gene (EGFR) mutations who represent effectiveness and well tolerance of EGFR-specific tyrosine kinase inhibitors (TKIs) therapy. Although the systemic efficacy of targeted agents is established, the efficacy of central nervous system (CNS) metastases is not as well characterized. In this article, we review recent data on the use of EGFR inhibitors for treatment of patients with NSCLC and CNS metastases. PMID:27561797

  17. Gamma knife radiosurgery for multiple brain metastases from non-small cell lung cancer. Comparison with whole brain radiation therapy

    International Nuclear Information System (INIS)

    The purpose of this retrospective study is to compare the effectiveness of gamma knife radiosurgery (GKS) with that of whole-brain radiation therapy (WBRT) for multiple cerebral metastases from non-small cell lung cancer. Among 302 cases with cerebral metastases from non-small cell lung cancer treated at the Chiba Cardiovascular Center and Chiba Cancer Center between 1990 and 1999, 100 consecutive patients filling the following 4 entry criteria were analyzed in this study: Up to 10 multiple brain lesions at initial MRI study; No surgically inaccessible tumors with more than 30 mm in diameter; No carcinomatous meningitis; More than 3 months of life expectancy. The patients were divided into two groups: the GKS group (66 patients) and the WBRT group (34 patients). In the GKS group, large lesions (≥30mm) were removed microsurgically and all other small lesions (<30 mm) were treated by GKS. New distant lesions were treated by repeated GKS without prophylactic WBRT. In the WBRT group, the patients were treated by the traditional combined therapy of WBRT and surgery. In both groups, chemotherapy was administered according to the primary physician's protocol. The two groups did not differ in terms of age, gender, initial Karnofsky Performance Scale (KPS) score, pathology of lung caner, number, and size of brain lesion, systemic control, and chemotherapy. Overall survival (OS), neurological survival (NS) and qualitative survival (QS) of the GKS group were longer than those of the WBRT group according to Kaplan-Meier's method. In a multivariate analysis the WBRT group also had significant poor prognostic factors for OS, NS and QS. GKS without prophylactic WBRT could be a primary choice of treatment method for patients with as many as 10 cerebral metastases from non-small cell lung cancer. (author)

    Highlights: • CT is more sensitive than PET/CT in detecting hepatic metastases. • PET/CT is more specific in detecting hepatic metastases. • CT and PET/CT have equal sensitivity in detecting extra hepatic metastases. • PET/CT is more specific in detecting extra hepatic metastases. • PET/CT has an impact of about 40% on changing the management strategies. - Abstract: Purpose: To investigate the efficacy of positron emission tomography/computed tomography (PET/CT) in detection and management of hepatic and extrahepatic metastases from gastrointestinal cancers. Materials and methods: Between February 2008 and July 2010, patients histopathologically diagnosed with gastrointestinal cancer and showing suspected metastasis on CT screening were subsequently evaluated with PET/CT. All patients were subgrouped according to histopathological origin and localization of the primary tumor. Localization of gastrointestinal cancers was further specified as lower gastrointestinal system (GIS), upper GIS, or hepato-pancreato-biliary (HPB). Both accuracy and impact of CT and PET/CT on patient management were retrospectively evaluated. Results: One hundred and thirteen patients diagnosed histopathologically with gastrointestinal cancers were retrospectively evaluated. Seventy-nine patients had adenocarcinoma and 34 patients other gastrointestinal tumors. Forty-one patients were in the upper GIS group, 30 patients in the HPB group, and 42 patients in the lower GIS group. Evaluation the diagnostic performance of PET/CT for suspected metastasis according to histopathological origin of the tumor, revealed that the sensitivity of PET/CT – although statistically not different – was higher in adenocarcinomas than in non-adenocarcinomas (90% (95% CI, 0.78–0.96) vs. 71.4% (95% CI, 0.45–0.88), P = 0.86).

  20. JTE-522, a selective COX-2 inhibitor, inhibits growth of pulmonary metastases of colorectal cancer in rats

    International Nuclear Information System (INIS)

    Epidemiological studies have shown that individuals who regularly consume NSAIDs have lower rates of mortality associated with colorectal cancer. Because COX-2 inhibitors prevent tumor growth through some mechanisms, we assessed the effect of JTE-522, a selective COX-2 inhibitor, on pulmonary metastases of colon cancer in a rat model. A suspension of 5 × 106 RCN-9 (rat colon cancer cells) was injected into the tail vein of 24 anesthetized male F344/DuCrj rats. Oral JTE-522 (0, 3, 10, or 30 mg/kg/day) was administered from the day before RCN-9 injection until the end of the study. Twenty-four days later, the lungs were removed from sacrificed rats and weighed. Pulmonary metastatic tumors were microscopically evaluated in the largest cross sections. We also performed immunohistochemical staining for both COX-2 and VEGF. JTE-522 dose-dependently decreased lung weight (p = 0.001) and the size of pulmonary metastatic tumors (p = 0.0002). However, the differences in the number of metastatic tumors among 4 groups were insignificant. Significant adverse effects of JTE-522 were undetectable. Immunohistochemical staining showed high levels of both COX-2 and VEGF in pulmonary metastatic tumors. JTE-522 dose-dependently decreased the size, but not the number of pulmonary metastases. COX-2 inhibitors might block metastatic tumor growth, but not actual metastasis. Selective COX-2 inhibitors might be useful as therapeutic agents that inhibit the growth of metastatic tumors, as well as the tumorigenesis of colorectal cancer

    Skeletal metastases result in significant morbidity and mortality.This is particularly true of cancers with a strong predilection for the bone,such as breast,prostate,and lung cancers.There is currently no reliable cure for skeletal metastasis,and palliative therapy options are limited.The Wnt signaling pathway has been found to play an integral role in the process of skeletal metastasis and may be an important clinical target.Several experimental models of skeletal metastasis have been used to find new biomarkers and test new treatments.In this review,we discuss pathologic process of bone metastasis,the roles of the Wnt signaling,and the available experimental models and treatments.

  2. Regional differences in prostaglandin E2 metabolism in human colorectal cancer liver metastases

    International Nuclear Information System (INIS)

    Prostaglandin (PG) E2 plays a critical role in colorectal cancer (CRC) progression, including epithelial-mesenchymal transition (EMT). Activity of the rate-limiting enzyme for PGE2 catabolism (15-hydroxyprostaglandin dehydrogenase [15-PGDH]) is dependent on availability of NAD+. We tested the hypothesis that there is intra-tumoral variability in PGE2 content, as well as in levels and activity of 15-PGDH, in human CRC liver metastases (CRCLM). To understand possible underlying mechanisms, we investigated the relationship between hypoxia, 15-PGDH and PGE2 in human CRC cells in vitro. Tissue from the periphery and centre of 20 human CRCLM was analysed for PGE2 levels, 15-PGDH and cyclooxygenase (COX)-2 expression, 15-PGDH activity, and NAD+/NADH levels. EMT of LIM1863 human CRC cells was induced by transforming growth factor (TGF) β. PGE2 levels were significantly higher in the centre of CRCLM compared with peripheral tissue (P = 0.04). There were increased levels of 15-PGDH protein in the centre of CRCLM associated with reduced 15-PGDH activity and low NAD+/NADH levels. There was no significant heterogeneity in COX-2 protein expression. NAD+ availability controlled 15-PGDH activity in human CRC cells in vitro. Hypoxia induced 15-PGDH expression in human CRC cells and promoted EMT, in a similar manner to PGE2. Combined 15-PGDH expression and loss of membranous E-cadherin (EMT biomarker) were present in the centre of human CRCLM in vivo. There is significant intra-tumoral heterogeneity in PGE2 content, 15-PGDH activity and NAD+ availability in human CRCLM. Tumour micro-environment (including hypoxia)-driven differences in PGE2 metabolism should be targeted for novel treatment of advanced CRC

    The aim was to investigate whether the biochemical prognostic markers TIMP-1, Ki67, and HER2 could predict metastatic spread to non-sentinel nodes (NSN) in breast cancer patients with micrometastases to sentinel node (SN). We included all breast cancer patients with micrometastases to SN operated...... tumor characteristics were retrieved from the Danish Breast Cancer Cooperative Group database. Immunohistochemical analyses of TIMP-1 and Ki67 and measurements of HER2 on formalin-fixed paraffin-embedded tumor tissue were performed. No significant differences in the immunoreactivity of TIMP-1 and Ki67...... were found between patients with and without NSN metastases. Six of seven HER2 positive patients did not have NSN metastases, but the results did not reach statistical significance. Despite being prognostic markers in breast cancer, TIMP-1 and Ki67 could not predict NSN metastases in women with...

    Radium-223 dichloride is an alpha-emitting radiopharmaceutical shown to prolong survival in patients with castrate-resistant prostate cancer (CRPC) and symptomatic skeletal metastases. This report describes in two patients the acute changes in bone metastatic activity detected by F-18 choline PET/CT imaging midway during treatment with radium-223 dichloride. In addition to visual and standardized uptake value analysis, changes in the whole-body tumor burden were quantified by measuring the difference in net metabolically active tumor volume (MATV) and total lesion activity (TLA) between pre- and mid-treatment PET scans. After the third dose of radium-223 dichloride, near-total disappearance of abnormal skeletal activity was observed in one case (net MATV change from 260.7 to 0.8 cc; net TLA change from 510.7 to 2.1), while a heterogeneous tumor response was observed in the other (net MATV change from 272.2 to 241.3 cc; net TLA change from 987.1 to 779.4). Corresponding normalization and persistent elevation in serum alkaline phosphatase levels were observed in these cases, respectively. Further research is needed to determine the predictive value of serial F-18 choline PET/CT imaging in patients receiving radium-223 dichloride for CRPC.

    2014-01-01

    Background: Since the liver metastases rather than the colorectal cancer itself is the main determinant of patient’s survival, the ‘Liver-First Approach (LFA)’ with upfront chemotherapy followed by a hepatic resection of colorectal liver metastases (CLM) and finally a colorectal cancer resection was proposed. The aim of this review was to analyse the evidence for LFA in patients with colorectal cancer and synchronous CLM. Methods: A literature search of databases (MEDLINE and EMBASE) to identify published studies of LFA in patients with colorectal cancer and synchronous CLM was undertaken focussing on the peri-operative regimens of LFA and survival outcomes. Results: Three observational studies and one retrospective cohort study were included for review. A total of 121 patients with colorectal cancer and synchronous CLM were selected for LFA. Pre-operative chemotherapy was used in 99% of patients. One hundred and twelve of the initial 121 patients (93%) underwent a hepatic resection of CLM. In total, 60% had a major liver resection and the R0 resection rate was 93%. Post-operative morbidity and mortality after the hepatic resection were 20% and 1%, respectively. Ultimately, 89 of the initial 121 (74%) patients underwent a colorectal cancer resection. Post-operative morbidity and mortality after a colorectal resection were 50% and 6%, respectively. The median overall survival was 40 months (range 19–50) with a recurrence rate of 52%. Conclusions: Current evidence suggests that LFA is safe and feasible in selected patients with colorectal cancer and synchronous CLM. Future studies are required to further define patient selection criteria for LFA and the exact role of LFA in the management of synchronous CLM. PMID:23509899

  9. Bone-seeking radiopharmaceuticals in skeletal malignancy: evolution, not revolution

    International Nuclear Information System (INIS)

    Many advanced malignancies are complicated by skeletal metastases, with attendant pain and disability. External beam radiotherapy is still the most effective treatment for isolated lesions. Bone-seeking radiopharmaceuticals were perceived as a means of delivering radiation to multiple lesions simultaneously. A wide variety of radioisotopes have been used in this endeavor, with myelosuppression being the most significant potential adverse effect. Benefits of treatment are modest, including a transient improvement in pain control and perhaps prolongation of the treatment-free period. This is best demonstrated in prostate cancer with lower responses by skeletal metastases from breast and lung cancers. However, the treatment is yet to produce any improvement in patient survival. Experimental approaches to improve treatment efficacy include combination with cytotoxic therapy, and administration earlier in the course of the disease. Bone seeking radiopharmaceuticals have been used in treatment of advanced osteosarcoma in humans and canines and achieved effective palliation. The myelosuppressive effects of these agents have been exploited in patients with multiple myeloma to assist in attaining myeloablation prior to stem cell transplantation. Development of more potent non-radiolabelled bisphosphonates and recognition of their antitumour effect against several tumours has sparked a recrudescence of interest in their use for bone metastases. Set against these developments, the role of bone-seeking radiopharmaceuticals in skeletal metastases may need to be redefined

  10. The Effect of Early Detection of Occult Brain Metastases in HER2-Positive Breast Cancer Patients on Survival and Cause of Death

    International Nuclear Information System (INIS)

    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.

    Purpose: We previously developed a multigene expression model of tumor radiation sensitivity index (RSI) with clinical validation in multiple independent cohorts (breast, rectal, esophageal, and head and neck patients). The purpose of this study was to assess differences between RSI scores in primary colon cancer and metastases. Methods and Materials: Patients were identified from our institutional review board–approved prospective observational protocol. A total of 704 metastatic and 1362 primary lesions were obtained from a de-identified metadata pool. RSI was calculated using the previously published rank-based algorithm. An independent cohort of 29 lung or liver colon metastases treated with 60 Gy in 5 fractions stereotactic body radiation therapy (SBRT) was used for validation. Results: The most common sites of metastases included liver (n=374; 53%), lung (n=116; 17%), and lymph nodes (n=40; 6%). Sixty percent of metastatic tumors, compared with 54% of primaries, were in the RSI radiation-resistant peak, suggesting metastatic tumors may be slightly more radiation resistant than primaries (P=.01). In contrast, when we analyzed metastases based on anatomical site, we uncovered large differences in RSI. The median RSIs for metastases in descending order of radiation resistance were ovary (0.48), abdomen (0.47), liver (0.43), brain (0.42), lung (0.32), and lymph nodes (0.31) (P<.0001). These findings were confirmed when the analysis was restricted to lesions from the same patient (n=139). In our independent cohort of treated lung and liver metastases, lung metastases had an improved local control rate compared to that in patients with liver metastases (2-year local control rate of 100% vs 73.0%, respectively; P=.026). Conclusions: Assessment of radiation sensitivity between primary and metastatic tissues of colon cancer histology revealed significant differences based on anatomical location of metastases. These initial results warrant validation in a larger

  15. CT-guided 125I seed implantation for locoregional lymph node metastases in patients with recurrent gastric cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the safety and short term effect of 125I seed implantation for locoregional lymph node metastases in patients with recurrent gastric cancer. Methods: The data of 23 gastric cancer patients with locoregional lymph node metastases treated by CT-guided 125I seed implantation were retrospectively studied. Patient characteristics and survival data were collected and analyzed. The procedure for seed implantation was performed under CT guidance according to preoperative treatment planning. Evaluation of short-term effect was carried out two months after the 125I seed implantation using response evaluation criteria in solid tumors (RECIST). The 1-, 2-and 3-year survival rates were plotted using the life table method.The potential predictors of survival were tested using univariate Cox models. Log-rank method was used to test the difference of survival in subgroups with tumor size >3 cm and <3 cm. Twenty patients underwent fluoropyrimidine-based chemotherapy after 125I seed implantation. Results: None of the 23 patients had serious complications. Two months after 125I seed implantation, the CR, PR and PD rates were 60.9% (14/23), 21.7% (5/23) and 17.4% (4/23), respectively. The median survival time was (22.1±5.1) months,and the 1-, 2-, 3-year survival rates were (87±7)%, (47± 11)% and (13 ±9)%, respectively. The tumor size (longest diameter) was the most significant factor for prognosis (χ2=9.752, P=0.002). Patients with tumor <3 cm in diameter had longer survival time than those with tumor >3 cm ((30.0±5.1) vs (17.0±5.0) months; χ2=5.828, P=0.016). Conclusion: CT-guided brachytherapy using 125I seed implantation is a safe and effective method for palliative treatment of locoregional lymph node metastases for recurrent gastric cancer. (authors)

    Lok, Edwin

    Whole brain radiation is the standard treatment for patients with brain metastasis but unfortunately tumors can recover from radiation-induced damage with the help of the immune system. The hypothesis that differences in immunokines in the cerebrospinal fluid (CSF) pre- and post-irradiation could reveal tumor biology and correlate with outcome of patients with metastatic breast cancer to the brain is tested. Collected CSF samples were analyzed using Luminex's multiplexing assays to survey global immunokine levels while Enzyme-Linked Immunosorbent Assays were used to quantify each individual immunokines. Cluster analysis was performed to segregate patients based on their common immunokine profile and each cluster was correlated with survival and other clinical parameters. Breast cancer brain metastasis was found to have altered immunokine profiles in the CSF, and that Interleukin-1α expression was elevated after irradiation. Therefore, immunokine profiling in the CSF could enable cancer physicians to monitor the status of brain metastases.

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

  19. Development of combining bone scintigraphy and tumor markers in the diagnosis of bone metastases

    International Nuclear Information System (INIS)

    Bone is one of the most common metastatic sites for advanced cancers. The skeletal-related events caused by bone metastases could have a significant influence on patient's clinical outcome and quality of life. Currently, bone scintigraphy is the first choice for detecting bone metastases. Although the sensitivity is high, the specificity of bone scintigraphy is still very low. It has been reported that by combining bone scintigraphy and tumor markers, the specificity can be significantly increased. Meantime, the sensitivity and accuracy of bone scintigraphy in diagnosis of bone metastases can be improved. We reviewed the literatures in the recent years to evaluate the potential value of combination with bone scintigraphy and tumor markers in the diagnoses of bone metastases. (authors)

    Objective: To evaluate the treatment outcomes in lung cancer patients with brain metastases (BM) after stereotactic radiotherapy (SRT) according to magnetic resonance imaging (MRI) findings and the Response Evaluation Criteria In Solid Tumors (RECIST). Methods: A retrospective analysis was performed on 31 lung cancer patients with 60 BM lesions who were treated with SRT. Tumor responses were evaluated according to MRI findings and the RECIST. Results: The MRI after SRT showed that (1) 14 lesions recurred, with nodular enhancement in 8 lesions, homogeneous enhancement in 5 lesions, and inhomogeneous enhancement in 1 lesion; (2) 11 lesions (18%) had suspected progression, with homogeneous enhancement in 5 lesions, inhomogeneous enhancement in 3 lesions, peripheral enhancement in 2 lesions,and nodular enhancement in 1 lesion; (3) 35 lesions were controlled, with decreased volume or disappearance in 19 lesions, insignificant volume change in 10 lesions, and increased volume in 6 lesions; (4) the overall response rate was 76.7% (suspected progression + controlled). According to the RECIST, 15 lesions (25%) achieved a complete response (CR), 9 lesions (15%) achieved a partial response (PR), 12 lesions (20%) had stable disease,and 24 lesions (40%) had progressive disease, and the response rate (CR + PR) was 40%. Conclusions: There are various MRI findings for brain metastases in lung cancer patients after SRT, and 18% of the lesions are difficult to evaluate by MRI. RECIST underestimates the short-term effect of SRT. (authors)

    International Nuclear Information System (INIS)

    Purpose: This case was reported to describe a case of cure in a 61-year old patient with squamous cell lung cancer and multiple extrathoracic metastasis. Methods and materials: A left upper lobectomy of lung for a squamous cell carcinoma was performed on a 61-year old man with curative intent. Fourt months later two osseous metastases were irradiated with Cobalt 60 up to 40 Gy. Results: The two irradiated lesions showed continuously shrinkage as well as signs of recalcification. Eleven years later the patient shows clinically absolut well being and on CT there are no signs of recurrent disease of the lung or bone anymore. Discussion: To our knowledge has nobody so far reported of a case of a squamous cell lung cancer which was operated and irradiated on thus resulting in cure. Furtheron the authors discuss that it might well be worthwile to define subgroups in stage 4 non-small cell lung cancer (presence of extrathoracic metastases) which might benefit from a more aggressive treatment approach than pure palliation.

  2. Overexpression of β1-chain-containing laminins in capillary basement membranes of human breast cancer and its metastases

    International Nuclear Information System (INIS)

    Laminins are the major components of vascular and parenchymal basement membranes. We previously documented a switch in the expression of vascular laminins containing the α4 chain from predominantly laminin-9 (α4β2γ1) to predominantly laminin-8 (α4β1γ1) during progression of human brain gliomas to high-grade glioblastoma multiforme. Here, differential expression of laminins was studied in blood vessels and ductal epithelium of the breast. In the present study the expressions of laminin isoforms α1–α5, β1–β3, γ1, and γ2 were examined during progression of breast cancer. Forty-five clinical samples of breast tissues including normal breast, ductal carcinomas in situ, invasive ductal carcinomas, and their metastases to the brain were compared using Western blot analysis and immunohistochemistry for various chains of laminin, in particular laminin-8 and laminin-9. Laminin α4 chain was observed in vascular basement membranes of most studied tissues, with the highest expression in metastases. At the same time, the expression of laminin β2 chain (a constituent of laminin-9) was mostly seen in normal breast and carcinomas in situ but not in invasive carcinomas or metastases. In contrast, laminin β1 chain (a constituent of laminin-8) was typically found in vessel walls of carcinomas and their metastases but not in those of normal breast. The expression of laminin-8 increased in a progression-dependent manner. A similar change was observed from laminin-11 (α5β2γ1) to laminin-10 (α5β1γ1) during breast tumor progression. Additionally, laminin-2 (α2β1γ1) appeared in vascular basement membranes of invasive carcinomas and metastases. Chains of laminin-5 (α3β3γ2) were expressed in the ductal epithelium basement membranes of the breast and diminished with tumor progression. These results suggest that laminin-2, laminin-8, and laminin-10 are important components of tumor microvessels and may associate with breast tumor progression. Angiogenic switch

    2012-12-01

    Full Text Available CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients

    Full Text Available Introduction: Colorectal cancer (CRC is the 3rd leading cause of cancer-related death in the U.S. Many patients with CRC develop hepatic metastases as the sole site of metastases. Historical treatment options were limited to resection or conventional radiation therapy. Stereotactic body radiation therapy (SBRT has emerged as a rational treatment approach. This study reviews our experience with SBRT for patients with liver metastases from CRC.Material and Methods: Fourteen histologically confirmed hepatic CRC metastases in 11 consecutive patients were identified between November, 2004 and June, 2009 at Georgetown University. All patients underwent CT-based treatment planning; a few also had MRI or PET/CT. All patients had fiducial markers placed under CT guidance and were treated using the CyberKnife system. Treatment response and toxicities were examined; survival and local control were evaluated.Results: Most patients were treated to a single hepatic lesion (n=8, with a few treated to 2 lesions (n=3. Median treatment volume was 99.7 cm3, and lesions were treated to a median BED10 of 49.7 Gy (range: 28 – 100.8 Gy. Median follow-up was 21 months; median survival was 16.1 months, with 2-year actuarial survival of 25.7%. One-year local control was 72%. Among patients with post-treatment imaging, 8 had stable disease (80% and 2 had progressive disease (20% at first follow-up. The most common grade 1-2 acute toxicities included nausea and alterations in liver function tests; there was one grade 3 toxicity (elevated bilirubin, and no grade 4-5 toxicities.Discussion: SBRT is safe and feasible for the treatment of limited hepatic metastases from CRC. Our results compare favorably with outcomes from previous studies of SBRT. Further studies are needed to better define patient eligibility, study the role of combined modality treatment, optimize treatment parameters, and characterize quality of life after treatment.

  5. Fractionated stereotactic radiosurgery for patients with skull base metastases from systemic cancer involving the anterior visual pathway

    International Nuclear Information System (INIS)

    To analyze the tumor control, survival outcomes, and toxicity after stereotactic radiosurgery (SRS) for skull base metastases from systemic cancer involving the anterior visual pathway. We have analyzed 34 patients (23 females and 11 males, median age 59 years) who underwent multi-fraction SRS for a skull base metastasis compressing or in close proximity of optic nerves and chiasm. All metastases were treated with frameless LINAC-based multi-fraction SRS in 5 daily fractions of 5 Gy each. Local control, distant failure, and overall survival were estimated using the Kaplan-Meier method calculated from the time of SRS. Prognostic variables were assessed using log-rank and Cox regression analyses. At a median follow-up of 13 months (range, 2–36.5 months), twenty-five patients had died and 9 were alive. The 1-year and 2-year local control rates were 89% and 72%, and respective actuarial survival rates were 63% and 30%. Four patients recurred with a median time to progression of 12 months (range, 6–27 months), and 17 patients had new brain metastases at distant brain sites. The 1-year and 2-year distant failure rates were 50% and 77%, respectively. On multivariate analysis, a Karnofsky performance status (KPS) >70 and the absence of extracranial metastases were prognostic factors associated with lower distant failure rates and longer survival. After multi-fraction SRS, 15 (51%) out of 29 patients had a clinical improvement of their preexisting cranial deficits. No patients developed radiation-induced optic neuropathy during the follow-up. Multi-fraction SRS (5 x 5 Gy) is a safe treatment option associated with good local control and improved cranial nerve symptoms for patients with a skull base metastasis involving the anterior visual pathway

    A 77-year-old woman was referred because of local reoccurrence of cancer of the breast. Chest x-ray showed a mediastinal tumor with dislocation of the trachea to the right. A Tc-99m pertechnetate scan showed irregular tracer uptake in an enlarged left lobe of the thyroid gland. Ultrasound confirmed...... the diagnosis of a nodular goiter with intrathoracic growth of the left lobe. A SPECT/CT scan of the mediastinum clearly showed that the soft tissue tumor was the left lobe of the thyroid gland, and not lymphatic metastases....

  7. Brain imaging in lung cancer patients without symptoms of brain metastases: a national survey of current practice in England

    International Nuclear Information System (INIS)

    Aim: To determine current practice regarding brain imaging for newly diagnosed lung cancer patients without symptoms of brain metastases. Materials and methods: A survey questionnaire was sent by e-mail to all the lung cancer lead clinicians in England currently on the National Cancer Intelligence Network database. The survey asked whether brain imaging was used in new lung cancer patients without symptoms or signs to suggest brain metastases; and if so, which patient subgroups were imaged according to cell type, stage of disease, and intention to treat, and which techniques were used to image these patients. Responses were received between February and May 2014. Results: Fifty-nine of 154 centres replied to the survey (38%). Thirty of the 59 centres (51%) did not image the brain in these patients. Twenty-nine of the 59 (49%) centres imaged the brain in at least certain subgroups. Of those centres that did image the brain 21 (72%) used CT as the first-line imaging technique and six (20%) used MRI. Twenty-five of 59 (42%) centres stated that the 2011 NICE guidelines had led to a change in their practice. Conclusion: There is wide variation in practice regarding brain imaging in this patient group in England, with no brain imaging at all in approximately half of centres and a spectrum of imaging in the other half. When the brain is imaged, CT is the technique most commonly used. The 2011 NICE guidelines have led to some change in practice but not to national uniformity. - Highlights: • Ascertain current practice in brain imaging for staging asymptomatic lung cancer patients. • Survey questionnaire sent to all the lung cancer lead clinicians in England. • Wide variation in practice with regard to brain imaging in this patient group. • No brain imaging at all in approximately half of centres and a spectrum of imaging in the other half • The 2011 NICE guidelines have led to some change in practice but not to national uniformity

  8. Survival and prognostic factors in non-small cell lung cancer patients with spinal bone metastases. A retrospective analysis of 303 patients

    International Nuclear Information System (INIS)

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

    OBJECTIVE To understand the characteristics of celiac trunk lymph-node metastases of thoracic esophageal carcinoma and their influence on prognosis of the patients, and to investigate a reasonable range for regional celiac trunk lymph-node clearance.METHODS Clinical specimens of 241 patients receiving resection of a thoracic esophageal carcinoma were analyzed retrospectively.RESULTS The rate of the patient celiac lymph-node metastases was 32.4%(78/241), and of the lymph nodes examined, 9.8% were found to have metastasis. The extent of metastases adjacent to the common hepatic artery and celiac trunk and within the hepatoduodenal ligaments was 6.6%, 6.9% and 6.3%, respectively. The tumor site, extent of invasion and level of cell differentiation were the factors influencing lymph-node metastases, but they were unrelated to the length of the tumor. The overall rate of regional celiac recurrence for the patients 3 years after operation was 5.4%. The 3-year survivals for the patients with metastases of the celiac lymph nodes was 42.3%, which was lower compared to the non-metastatic patients (70.6%) (P<0.01).CONCLUSION Celiac lymph-node metastases are one of key factors affecting the prognosis of the patients receiving resection of esophageal cancer, and extensive clearance of the celiac-trunk lymph nodes can reduce the rate of postoperative regional metastases.

    Full Text Available Abstract Objective To investigate the prognostic significance of tumor necrosis factor receptor (TNFR,-associated factor 6 (TRAF6,-and ubiquitin in gastric cancer patients. Methods Biopsies of the rectus abdominis muscle were obtained intra operatively from 102 gastric cancer patients and 29 subjects undergoing surgery for benign abdominal diseases, and muscle TRAF6 and ubiquitin mRNA expression and proteasome proteolytic activities were assessed. Results TRAF6 was significantly upregulated in muscle of gastric cancer compared with the control muscles. TRAF6 was upregulated in 67.65% (69/102 muscle of gastric cancer. Over expression of TRAF6 in muscles of gastric cancer were associated with TNM stage, level of serum albumin and percent of weight loss. Ubiquitin was significantly upregulated in muscle of gastric cancer compared with the control muscles. Ubiquitin was upregulated in 58.82% (60/102 muscles of gastric cancer. Over expression of ubiquitin in muscles of gastric cancer were associated with TNM (Tumor-Node-Metastasis stage and weight loss. There was significant relation between TRAF6 and ubiquitin expression. Conclusions We found a positive correlation between TRAF6 and ubiquitin expression, suggesting that TRAF6 may up regulates ubiquitin activity in cancer cachexia. While more investigations are required to understand its mechanisms of TRAF6 and ubiquitin in skeletal muscle. Correct the catabolic-anabolic imbalance is essential for the effective treatment of cancer cachexia.

    Recent studies have suggested that in humans and animals with significant skeletal pain, changes in the mechanical hypersensitivity of the skin can be detected. However, whether measuring changes in skin hypersensitivity can be a reliable surrogate for measuring skeletal pain itself remains unclear. To explore this question, we generated skeletal pain by injecting and confining GFP-transfected NCTC 2472 osteosarcoma cells unilaterally to the femur of C3H male mice. Beginning at day 7 post-tumor injection, animals were administered vehicle, an antibody to the P2X3 receptor (anti-P2X3) or anti-NGF antibody. Pain and analgesic efficacy were then measured on days 21, 28, and 35 post-tumor injection using a battery of skeletal pain-related behaviors and von Frey assessment of mechanical hypersensitivity on the plantar surface of the hind paw. Animals with bone cancer pain treated with anti-P2X3 showed a reduction in skin hypersensitivity but no attenuation of skeletal pain behaviors, whereas animals with bone cancer pain treated with anti-NGF showed a reduction in both skin hypersensitivity and skeletal pain behaviors. These results suggest that although bone cancer can induce significant skeletal pain-related behaviors and hypersensitivity of the skin, relief of hypersensitivity of the skin is not always accompanied by attenuation of skeletal pain. Understanding the relationship between skeletal and skin pain may provide insight into how pain is processed and integrated and help define the preclinical measures of skeletal pain that are predictive end points for clinical trials.

    In order to evaluate the sensitivity of computed tomography (CT) scan in detecting the abdominal lymph node metastases, preoperative CT scan was performed in 16 patients with carcinoma of the esophagus and gastric cardia. Ten patients (62.5%) had pathological evidence of lymph node metastases in the abdominal cavity and 4 of them were identified to involve the para-aortic nodes. CT scan correctly demonstrated the lymph node metastases in the para-aortic and celiac axisis areas, but failed to detect other abdominal lymph node involvements, which were small enough to be excised by operation. The para-aortic nodes on the CT scan showed the following two features; one was nodular mass in shape, which did not obscure the aorta or inferior vena cava, and the other was conglomerated mass, which was difficult to be distinguished from the aorta. The former was resectable and the latter was not.

  14. MRI detection of brain metastases at initial staging of small-cell lung cancer

    International Nuclear Information System (INIS)

    We prospectively investigated 40 patients with small-cell carcinoma of the lung (SCLC) for signs of brain metastasis by neurological examination and MRI of the brain, to determine the significance of MRI for staging. MRI could not be completed in one patient, who was excluded from the study. The MRI studies of the remaining patients showed no abnormalities in 12, cerebral infarcts in 2 and brain metastases in 11 patients, of whom 3 no relevant symptoms. Nonenhancing white matter lesions were found in 14 patients. In 3 of the 4 patients with an abnormal neurological examination at diagnosis, nonenhancing white matter lesions later developed into contrast enhancing lesions compatible with breain metastases; in 2, this occurred during the course of the chemotherapy. MRI did not change the clinical staging in patients with asymptomatic brain metastases. (orig.)

    Full Text Available Radiation therapy is associated with a variety of complications, including the development of primary skin cancers in the radiated region. However, it is rare for patients with visceral cancers who are treated with radiation therapy to subsequently develop cutaneous metastasis within the radiation port. We describe two patients with internal malignancies who developed cutaneous metastases within their radiation ports following radiotherapy. In addition, we used PubMed to perform an extensive literature review and identify additional reports of cutaneous metastasis within a radiation port. We excluded patients who developed melanoma or primary skin cancers in the radiation port. We also excluded patients with non-solid organ malignancies. Herein, we summarize the characteristics of 23 additional patients who experienced radiation port cutaneous metastases and explore possible mechanisms for the occurrence of radiation port cutaneous metastases.

    BACKGROUND: Benefit from axillary lymph node dissection in sentinel node positive breast cancer patients is under debate. Based on data from 1820 Danish breast cancer patients operated in 2002-2008, we have developed two models to predict high risk of non-sentinel node metastases when...... cohort to 0.60 in the validation cohort. When dividing patients with isolated tumor cells into high and low risk of non-sentinel node metastases according to number of risk factors present, 37% in the high-risk group had non-sentinel node metastases. Specificity and sensitivity was 0.48 and 0...... micrometastases or isolated tumor cells are found in sentinel node. The aim of this study was to validate these models in an independent Danish dataset. MATERIAL AND METHODS: We included 720 breast cancer patients with micrometastases and 180 with isolated tumor cells in sentinel node operated in 2009-2010 from...

  17. The value of performing head CT in screening for cerebral metastases in patients with potentially resectable non-small cell lung cancer: experience from a UK cardiothoracic centre

    International Nuclear Information System (INIS)

    AIM: To evaluate the whether screening for cerebral metastases in neurologically intact patients with potentially resectable non-small cell lung cancer patients is both worthwhile and cost-effective. METHODS: We prospectively performed computed tomography (CT) of the head in 105 consecutive patients with potentially resectable lung cancer over an 18-month period. None of these patients had neurological symptoms or signs. RESULTS: Five patients (4.8%) with cerebral metastases were identified using CT. At our institution the financial saving of avoiding five thoracotomies was 45,000 Pounds, whilst the cost of performing 105 head CTs was 16,000 Pounds. This represented a substantial saving for the healthcare provider and preserved the quality of life in five patients. CONCLUSIONS: We conclude that screening for cerebral metastases in neurologically intact patients with potentially resectable non small cell lung cancer patients is both worthwhile and cost effective

    Brain metastasis is a major cause of systemic cancer morbidity and mortality. Many factors participate in the development and maintenance of brain metastases. The survival of the metastasis depends upon crucial interactions between tumour cells and the brain microenvironment during its development at the new site. This review focuses on the pathobiological mechanisms involved in the establishment and regulation of brain metastases. Developments in molecular biology have vastly expanded our kn...

  19. Utility of Brain PET-MRI in the restaging of a colorectal cancer with brain metastases

    International Nuclear Information System (INIS)

    We report a case of a 47 year-old male diagnosed with carcinoma of sigmoid who presented initially with lung metastases and later with a single brain metastasis which was surgically removed. During follow up, brain tumor recurrence was detected by FDG PET-MRI scan up to 4 times using radiosurgery and /or stereotactic radiotherapy for salvage. The FDG PET-MRI study was useful and crucial for the detection of brain metastases and to guide treatment. Brain re-irradiation is useful to improve symptoms and survival, but may also have toxic affects so its indication must be cautious and applied in selected patients

    Full Text Available Draupadi B TalrejaDepartment of Medicine, David Geffen School of Medicine at UCLA and Northridge Hospital Medical Center, Northridge, CA, USAAbstract: Patients with bone metastases are at risk of skeletal-related events such as pathologic fractures, spinal cord compression, the need for orthopedic surgery to bone, and palliative radiotherapy for severe bone pain. Antiresorptive therapies have demonstrated efficacy for reducing the risk of skeletal-related events and ameliorating bone pain. Despite the well documented clinical benefits of antiresorptive therapies, patient benefits can be limited or compromised by nonadherence with scheduled therapy. Potential reasons for poor compliance include lack of understanding of how antiresorptive therapies work, neglecting the importance of bone health in maintaining quality of life, and being unaware of the potentially debilitating effects of skeletal-relat
