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

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

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

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

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

  8. Bone scintiscanning in metastases

    1986-01-01

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

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

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

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

    2018-01-01

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

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

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

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

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

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

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

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

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

    1996-01-01

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

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

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

    Basal cell carcinoma (BCC) rarely metastasizes. However, this unfortunate outcome can occur, usually in neglected tumors. We report a 52-year-old man with a BCC on the left chest that enlarged and then ulcerated over a 6-year period. Metastasis of the tumor to lymph nodes in the left axilla resulted, but the patient remains free of disease 24 months after wide excision, lymph node dissection, and local radiation therapy to the axilla.

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases.

    Full Text Available Melanomas are malignant neoplasms that originate from melanocytes. The most common are on the skin and mucous membranes. Choroidal melanomas are quite different from cutaneous melanomas with regard to presentation, metastases, and treatment. We report two cases of metastatic gastric malignant melanoma of the eye and skin, with reference to the literature. The first patient was a woman aged 23 years, who underwent gastrectomy 22 months after enucleation of the eye due to malignant choroid melanoma. The second patient was a man, 72 years old, who underwent surgery 28 months before because of malignant melanoma of the skin of the forehead. Paraffin sections, 4 μm thick were stained using a classic method, as well as immunohistochemical DAKO APAAP method, using a specific S - 100 antibody and Melan A antibodies. The stomach is considered a rare place for the development of metastases. Metastases in the stomach are often limited to the submucosal as well as the serousmuscular layer, as noted in one of our patients. Metastatic melanoma of the gastrointestinal tract should be suspected in any patient with a history of malignant melanoma and new gastrointestinal symptoms. Because of the similarity between certain common histopathological types of malignant melanoma, primarily achromatic, and types of primary cancers of the stomach, the following immunohistochemical studies are needed: Melan A and S - 100 protein ( markers of malignant melanoma , as well as mucins: MUC5AC, MUC2 and CDX2 ( markers of different types of primary gastric carcinoma.

    Substantial proportions of patients with metastatic melanoma develop brain metastases during the course of their disease, often resulting in significant morbidity and death. Despite recent advances with BRAF/MEK and immune-checkpoint inhibitors in the treatment of patients who have melanoma with extracerebral metastases, patients who have melanoma brain metastases still have poor overall survival, highlighting the need for further therapy options. A deeper understanding of the molecular pathways involved in the development of melanoma brain metastases is required to develop more brain-specific therapies. Here, the authors summarize the currently known preclinical data and describe steps involved in the development of melanoma brain metastases. Only by knowing the molecular background is it possible to design new therapeutic agents that can be used to improve the outcome of patients with melanoma brain metastases.

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

  14. Radionuclide therapy of bone metastases

    Palmedo, H.; Bucerius, J.

    2008-01-01

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

    Purpose: To determine the efficacy and safety of radiosurgery in patients with large brain metastases treated with radiosurgery. Patients and Methods: Eighty patients with large brain metastases (>14 cm 3 ) were treated with radiosurgery between 1998 and 2009. The mean age was 59 ± 11 years, and 49 (61.3%) were men. Neurologic symptoms were identified in 77 patients (96.3%), and 30 (37.5%) exhibited a dependent functional status. The primary disease was under control in 36 patients (45.0%), and 44 (55.0%) had a single lesion. The mean tumor volume was 22.4 ± 8.8 cm 3 , and the mean marginal dose prescribed was 13.8 ± 2.2 Gy. Results: The median survival time from radiosurgery was 7.9 months (95% confidence interval [CI], 5.343–10.46), and the 1-year survival rate was 39.2%. Functional improvement within 1–4 months or the maintenance of the initial independent status was observed in 48 (60.0%) and 20 (25.0%) patients after radiosurgery, respectively. Control of the primary disease, a marginal dose of ≥11 Gy, and a tumor volume ≥26 cm 3 were significantly associated with overall survival (hazard ratio, 0.479; p = .018; 95% CI, 0.261–0.880; hazard ratio, 0.350; p = .004; 95% CI, 0.171–0.718; hazard ratio, 2.307; p = .006; 95% CI, 1.274–4.180, respectively). Unacceptable radiation-related toxicities (Radiation Toxicity Oncology Group central nervous system toxicity Grade 3, 4, and 5 in 7, 6, and 2 patients, respectively) developed in 15 patients (18.8%). Conclusion: Radiosurgery seems to have a comparable efficacy with surgery for large brain metastases. However, the rate of radiation-related toxicities after radiosurgery should be considered when deciding on a treatment modality.

    We described magnetic resonance (MR) features of peribiliary metastasis and of periductal infiltrative cholangiocarcinoma. We assessed 35 patients, with peribiliary lesions, using MR 4-point confidence scale. T1-weighted (T1-W), T2-weighted (T2-W) and diffusion-weighted images (DWI) signal intensity, enhancement pattern during arterial, portal, equilibrium and hepatobiliary phase were assessed. We identified 24 patients with periductal-infiltrating cholangiocellular carcinoma. The lesions in 34 patients appeared as a single tissue, while in a single patient, the lesions appeared as multiple individual lesions. According to the confidence scale, the median value was 4 for T2-W, 4 for DWI, 3.6 for T1-W in phase, 3.6 for T1-W out phase, 3 for MRI arterial phase, 3.2 for MRI portal phase, 3.2 for MRI equilibrium phase and 3.6 for MRI hepatobiliary phase. According to Bismuth classification, all lesions were type IV. In total, 19 (54.3%) lesions were periductal, 15 (42.9%) lesions were intraperiductal, and 1 (2.8%) lesion was periductal intrahepatic. All lesions showed hypointense signal in T1-W and in ADC maps and hyperintense signal in T2-W and DWI. All lesions showed a progressive contrast enhancement. There was no significant difference in signal intensity and contrast enhancement among all metastases and among all metastases with respect to CCCs, for all imaging acquisitions (p value >0.05). MRI is the method of choice for biliary tract tumors thanks to the possibility to obtain morphological and functional evaluations. T2-W and DW sequences have highest diagnostic performance. MRI does not allow a correct differential diagnosis among different histological types of metastasis and between metastases and CCC.

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

    Carcinosarcoma of the prostate is an uncommon malignancy with poor long-term prognosis. The cancer is typically discovered at an advanced stage, and with less than 100 reported cases, there is limited literature concerning treatment options. Our patient presented with a history of benign prostatic hypertrophy, erectile dysfunction, and nocturia. Biopsy of his prostate indicated that the patient had prostatic adenocarcinoma, but histopathology after prostatectomy revealed carcinosarcoma. It has been over six years since this patient's diagnosis of carcinosarcoma. Over this span of time, he has received a radical prostatectomy, radiotherapy, and androgen ablative therapy. The patient also developed multiple lung metastases that have been treated with video-assisted thoracic surgery and stereotactic body radiosurgery. Overall, he has remained unimpaired and in good condition despite his aggressive form of cancer.

    Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient.

    Eighteen tumor samples from 11 patients with metastatic colorectal cancer were cytogenetically analyzed after short-term culturing. Of the 13 metastases examined, 11 were from lymph nodes, 1 from the peritoneum and 1 from the lung. In 5 of the 11 patients, matched samples from the primary tumor...... and lymph node metastases were analyzed. Cytogenetic similarities between the primary and secondary lesions were found in all 5 cases, indicating that many of the chromosomal aberrations presumably occurred before disease spreading took place.

    For our study, where clinical and scintigraphic observation seldom lasts more than two years and where measurable metastases always exceed 1 cm 3 , the exponential model was adopted and our results were all calculated with GERSTENBERG's formula which gives an apparent doubling time. The liver metastases were measured on the scintigraphic image obtained, a more or less sharply limited blank which makes for a first difficulty of judgement. Two magnascanner V type PICKER 5-inch crystal scintigraphs were used, giving three images simultaneously by a transcriber made up of a stylus and a light spot built into the detection system. The isotope used is colloidal gold ( 198 Au) phagocytized by the Kuepfferian reticulo-endothelial system. The doubling time for liver metastase scintigraphic images calculated for fifteen patients having undergone one or more isotopic checks after a first metastase image was discovered range from 10 to 103 days [fr

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

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

    Less than 3% of all breast cancers originate from a primitive extra mammary. In 40% of cases it is the first manifestation of the primitive properly studied but 80% are associated with widely disseminated disease. It typically presents as a nodule on external quadrant s painful in half the cases. The majority (60%) of metastases derived from breast contralateral breast tumors are believed to via the lymphatic system. of the ; extra mammary the most common tumors are melanoma; hematologic and neuroendocrine. Although some imaging characteristics can guide diagnosis is histological. Cytology has good performance in experienced hands; but up to 25% of cases there may be difficulty in establishing diagnosis. Treatment depends on the type of tumor. Mastectomy should not be practiced or axillary clearance routine as is generally the context of disease disseminated. Radiation therapy may be useful for local control. It has been proposed laser ablation but no experience with it. The overall prognosis is bad. For a man of 45 with a breast metastasis occurs only a clear cell carcinoma of the kidney

    In addition to personal observations of 77 patients with one or more metastatic sites in the gastrointestinal tract, the authors reviewed over 1000 similar cases in the literature. The general radiologic aspects of each location (oesophagus, stomach, intestine, colon/rectum) are discussed. The pathophysiology of this type of metastasis explains the radiologic images obtained during barium transit examinations. The lymphatic type of spread observed in the oesophageal region in connection with carcinoma of the breast is the origin of stenosis of the middle third. The haematogenous type of diffusion encountered during melanomas creates intramural or intraluminal radiologic images. Two means of spread can be observed in the stomach. Haematogenous spread can result in frequently multiple and ulcerated nodular submucosal lesions from melanomas and bronchogenic carcinomas; it can also cause a more or less stenotic invasive image, especially in connection with carcinoma of the breast. Dissemination by means of the mesenteric reflections, and in particular around the gastrocolic ligament, explains the spread of a carcinoma of the transverse colon towards the stomach. The most frequent secondary sites in the gastrointestinal tract occur in the small intestine, the majority of these metastases being caused by pelvic tumours. Whether occurring in the small intestine or the colon, the patophysiology is similar: direct invasion by a non-contiguous primary carcinoma along the fascias and mesenteric attachments (more rarely by lymphatic permeation), dissemination by the peritoneal fluid or haematogenuous spread. In the first two types of dissemination cited, the image encountered is often hard to differentiate from radiation-induced lesions. (orig.)

  11. The Treatment of Melanoma Brain Metastases.

    2016-12-01

    Melanoma is the malignancy with the highest rate of dissemination to the central nervous system once it metastasizes. Until recently, the prognosis of patients with melanoma brain metastases (MBM) was poor. In recent years, however, the prognosis has improved due to high-resolution imaging that facilitates early detection of small asymptomatic brain metastases and early intervention with local modalities such as stereotactic radiosurgery. More recently, a number of systemic therapies have been approved by the Food and Drug Administration for metastatic melanoma, resulting in improved survival for many MBM patients. Registration trials for these newer therapies excluded patients with untreated brain metastases, and a number of studies specifically tailored to this population of patients have been conducted or are underway. Herein, we review contemporary locoregional and systemic therapies and describe the unique challenges posed by treatment of brain metastases, such as radionecrosis, cerebral edema, and pseudoprogression. Since the number of systemic and combined modality clinical trials has increased, we expect that the treatment landscape for patients with melanoma brain metastasis will change dramatically. In addition to ongoing clinical trials, which show great promise, we conclude that our understanding of intracranial metastasis remains quite limited. In addition to inter-disciplinary, multi-modality studies, bench-side work to better understand the process of cerebrotropism is needed to fuel more drug development and further improve outcomes.

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

    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.)

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

    Metastatic disease to the liver is an important disease from the diagnostic, prognostic and therapeutic points of view. Different imaging modalities, such as US, CT, scintigraphy, and MRI, have been used for detection, characterization, therapy planning, and follow-up of this disease with variable degrees of success and failure. This review handles the problems which face the different imaging modalities in diagnosis of liver metastases in view of the pathological background of the disease. It also discusses the indications, strong points, and shortcomings of each of the imaging modalities in diagnosis of metastases, and surveys the recent efforts done to improve their performance through the optimization of quality control and in the innovations in the field of contrast agents. Finally, a protocol is suggested for the clinical management of patients with liver metastases to optimize cost-effectiveness of the imaging modalities in this era of multimodality approach in diagnostic imaging.

    Metastatic disease to the liver is one of the major factors determining the outcome of colonic resection with curative interventions in human patients. Therefore, animal models for studies of liver metastasis have been developed. Humane endpoints are needed for the evaluation of the animal...... impression of the metastases was obtained. We suggest, as a new humane endpoint, that one animal should only have 1-2 separately growing metastases, each of a maximum size of 10 mm(2). In future, the method has to be developed further to measure the size of the metastases in a more quantitatively precise...... manner. Although the animal has to be anaesthetized each time, laparoscopy is considered a minor surgical procedure as only two small puncture wounds are made through the abdominal wall. Because laparoscopy offers a direct view of the hidden tumours and their sizes, as well as of possible complications...

  17. CyberKnife radiosurgery for brain metastases.

    Classic radiosurgery is a neurosurgical treatment concept for single-fraction irradiation of cerebral lesions not amenable to open surgery. Until recently it has been realized mainly by frame-based technologies (Gamma Knife; stereotactic linear accelerators). The CyberKnife described in 1997 is an image-guided frameless robotic technology for whole-body radiosurgery. It can be used for classic single-fraction radiosurgery and for hypofractionated treatments. The CyberKnife treatment procedure is completely non-invasive and can be repeated throughout the body if necessary. Brain metastases are an important and frequently treated indication of modern radiosurgery. Data concerning radiosurgical treatment of brain metastases with the CyberKnife are reviewed. Scientific evidence shows that the full-body applicability of the CyberKnife is not at the expense of an inferior intracranial treatment quality when compared to standard frame-based technology. The clinical results of CyberKnife single-fraction radiosurgery are in line with the published literature. The attractive therapeutic profile of CyberKnife radiosurgery is reflected by a high tumor control and a low toxicity and the repeatability of the treatments for recurrent metastases. Although hypofractionated treatments (in 3-5 fractions) of brain metastases have been performed with the CyberKnife to treat large metastases, the clinical significance of this new radiosurgical concept is unclear and requires further study. A new approach is to treat the resection cavity with radiosurgery after surgical removal of brain metastases. In this concept radiosurgery replaces fractionated radiation therapy as an adjunct to surgery. The initial results are very promising. The CyberKnife has been established as a modern non-invasive technology for intra- and extracranial radiosurgery. It adds to the oncological armamentarium and confers upon radiosurgery a greater emphasis as an oncological treatment concept. Copyright © 2012 S

    Objectives: The aim of this study is to determine MRI characteristics which indicate liver metastases of neuroendocrine tumors (NET) rather than metastases of other origin (non-NET). Methods: Sixty-nine patients with histopathologically proven liver metastases from NET and 69 patients with known liver metastases of other origin underwent MRI of the liver using a 1.5 T MR-scanner. Two board certified radiologists assessed presence of fluid–fluid-levels, number and distribution pattern, signal intensity (SI) characteristics, lesion homogeneity, presence of central necrosis and intratumoral hemorrhage in T2w and T1w non-contrast imaging. A multivariate logistic regression analysis was performed to determine the independent association of image findings and occurrence of NET. Results: Fluid–fluid-levels were identified in 19/69 of patients with NET-metastases, and in none of the patients in the control group (p < 0.0001). Hyperintense SI in T1w imaging, markedly hyperintense SI in T2w imaging, a disseminated distribution pattern and intratumoral hemorrhage were indicative of NET metastases (p < 0.05). After statistical adjustment for all significant MRI findings, fluid–fluid-levels (OR: 17.6, 95% CI: 1.9–166.5), strongly hyperintense SI in T2w (OR: 4.7, 95% CI: 1.8–12.7) and a disseminated distribution pattern (OR: 2.9, 95% CI: 1.1–7.4) were independent predictors for NET metastases. Conclusions: The presence of fluid–fluid-levels is highly indicative of NET liver metastases and can be used as an independent predictor to distinguish them from metastases of other origin.

    Full Text Available The management of brainstem metastases is challenging. Surgical treatment is usually not an option, and chemotherapy is of limited utility. Stereotactic radiosurgery has emerged as a promising palliative treatment modality in these cases. The goal of this study is to assess our single institution experience treating brainstem metastases with Gamma Knife radiosurgery (GKRS. This retrospective chart review studied 41 patients with brainstem metastases treated with GKRS. The most common primary tumors were lung, breast, renal cell carcinoma, and melanoma. Median age at initial treatment was 59 years. Nineteen (46% of the patients received whole brain radiation therapy (WBRT prior to or concurrent with GKRS treatment. Thirty (73% of the patients had a single brainstem metastasis. The average GKRS dose was 17 Gy. Post-GKRS overall survival at six months was 42%, at 12 months was 22%, and at 24 months was 13%. Local tumor control was achieved in 91% of patients, and there was one patient who had a fatal brain hemorrhage after treatment. Karnofsky performance score (KPS >80 and the absence of prior WBRT were predictors for improved survival on multivariate analysis (HR 0.60 (p = 0.02, and HR 0.28 (p = 0.02, respectively. GKRS was an effective treatment for brainstem metastases, with excellent local tumor control.

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

    Extrahepatic disease (EHD) has been considered a contraindication to hepatectomy. Over the last few years, some series reported interesting 5-year survival rates after resection with hepatic colorectal metastases and EHD free margins. Between August 1989 and October 2005, 116 patients underwent liver resection for colorectal metastases at Surgical Department of the University of Udine, Italy. Among these, we reviewed the data of 5 patients affected by EHD. In 3 patients there were also an anastomotic recurrence of the primary tumor, in 3 patients diaphragm was infiltrated by contiguous liver metastases. We performed in all the patients minor liver resections. We have associated the radiofrequence ablation of a lesion not surgically resectable with liver resection in one case. The surgical procedure was always considered as curative. We observed no case of operative mortality. The mean survival of the entire cohort is 23.2 months (range 4-42 months). Our study, even if based upon a limited number of patients, supports the thesis that extrahepatic disease in patients affected by colorectal cancer with hepatic metastases should not be considered as an absolute contraindication to liver resection especially for the cases in with local radical cure exeresis is achievable.

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

    The advancement in oncology therapies has made brain metastases treatment a major factor influencing the survival time and quality of life of patients with cancer. Although there are numerous publications on the issue, there is not yet to be consensus regarding the best strategy for treatment, which is probably due to population heterogeneity in terms of functional status, type of neoplasia, control of the systemic disease, and the number and localization of the lesions in the central nervous system. Our objective is to present general recommendations based on rational analysis in order to guide the practical management of brain metastases. With this purpose, a multidisciplinary team composed by neurosurgeons, neuro-oncologists, neuro-pathologist, radio therapist and neurologists was brought together, conducting a thorough search, in english and spanish, for publications in Pub- Med from 1980 to July 2006 (the starting period was set at the beginning of use of RM in medical practice). Review and original articles with n= or >20 were selected. Also, book chapters of renowned authors in the different consulted areas were included. The assessment of the literature, in addition to the experience of the authors allowed for the development of the 'Consensus for the brain metastases treatment'. Finally, the authors expect the present work will contribute to the multidisciplinary approach for the management of brain metastases with simple and practical recommendations, and probably stimulating future developments in this field.

    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.)

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

    Full Text Available Cancer metastases represent the most devastating aspect of malignancy, since the mortality of cancer patients is mainly related to the metastatic behavior of the primary neoplasm. Skin metastases are usually late events in the course of tumor progression. Excluding melanoma, the most common tumor to metastasize to the skin is breast cancer. Patients who develop cutaneous metastases rarely present with a zosteriform distribution. Herein, we present a 60-year-old female, an undiagnosed case of breast cancer, with zosteriform metastases along her right T2-T3 dermatome.

    Full Text Available So far, computed tomography (CT and magnetic resonance imaging (MRI have been used in the detection of basal cell carcinomas (BCC metastases. We have used PET-CT postoperatively to detect any further metastases of BCC not visible by other techniques. BCC of the trunk are reportedly larger than those located in the head and neck region. These tumors also have a higher incidence of metastasizing. Although it has been suggested in the literature that the TNM (Tumor–Nodes-Metastases system is not being used routinely for metastasizing BCC. There have been 19 reports of metastasizing BCC of the trunk. We present a case of a 78-year old male patient with large ulcerating metastasizing BCC of the trunk. The literature is reviewed for similar cases and the TNM system is applied.

    Purpose: This is the first Brazilian study intended to evaluate the response of pain relief with radiotherapy in three different fractionation and the clinical differences in managing pain in patients with painful bone metastases. Methods: Prospective study of patients with painful bone metastases referred to the Radiotherapy Sector of the Hospital de Cancer de Barretos for pain-relieving radiotherapy between March and December 2010. It is known that radiotherapy seems to alter the activation of osteoclast-mediated bone resorption, relieving pain in cases of painful bone metastases. Patients were assessed in relation to the status of pain intensity before and after the initiation of radiotherapy. Either a single fraction of 8Gy, five fractions of 4Gy or ten fractions of 3Gy were given. A visual analog scale (VAS) was applied by doctors, nurses and nursing technicians to assess pain intensity at each session of radiotherapy, and follow-up at 8, 30 and 90 days from the end of treatment. Results: We evaluated 92 consecutive patients, 48 male and 44 female, with a median age of 58 years. We found that 14% of patients referred from the Palliative Care or Clinical Oncology sectors need better pharmacological analgesia due to severe pain, compared with 40.5% of patients from the other sectors (p = 0.004). We also found that the onset of pain relief to patients receiving 10 fractions of 300cGy analgesia without changing the pre-radiotherapy analgesia occurred with significance after the fifth fraction. Improvement in pain experienced within 90 days of follow-up was found in eighty percent of patients, independent of fractionated radiotherapy, site of metastases and the clinical condition of the patient. Discussion/Conclusion: The Palliative Care and Clinical Oncology sectors expressed greater concern in regards to analgesia for the patient with painful bone metastases. Radiotherapy is an effective pain-relieving treatment in different fractionation studied, even though the

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

We also found that the onset of pain relief to patients receiving 10 fractions of 300cGy analgesia without changing the pre-radiotherapy analgesia occurred with significance after the fifth fraction. Improvement in pain experienced within 90 days of follow-up was found in eighty percent of patients, independent of fractionated radiotherapy, site of metastases and the clinical condition of the patient. Discussion/Conclusion: The Palliative Care and Clinical Oncology sectors expressed greater concern in regards to analgesia for the patient with painful bone metastases. Radiotherapy is an effective pain-relieving treatment in different fractionation studied, even though the

    Objective: To investigate the effect of stereotatic radiotherapy (SRT) for brain metastases. Methods Retrospect compare 66 patients treated by SRT with whole brain radiotherapy (WBRT+ SRT) to 26 patients treated by SRT alone. Results: The patients treated by WBRT+ SRT had significantly benefit in lesions recurrence (13.3% vs 42.2%), middle recurrence time (10.5 months vs 4.2 months) and middle survival time(13 months vs 6.5 months) over the patients treated by SRT, respectively (P<0.05). But there are no different in terms of improving of Karnofsky score, effective rate, one-year survival rate, one-year death rate between the two groups. Conclusion: WBRT+ SRT play an important role in treating brain metastases, by improving patients life quantity and reducing recurrence. (authors)

    Cancer invasion and metastases is a complex multistep process. In order for a tumor cell to successfully traverse all the steps of this process and initiate a metastatic colony, it must express the right combination of gene products. Such gene products may include proteins which regulate cell...... interaction with the basement membrane and cell motility. Tumor cells attach to the basement membrane glycoprotein laminin via the cell surface laminin receptor. The human laminin receptor was purified and molecularly cloned. The level of laminin receptor mRNA is a variety of human carcinoma cells correlated...... with the number of laminin receptors on the cell surface of these cells. Following attachment to the basement membrane, the tumor cell next secretes proteases which may degrade type IV collagen. A genetic linkage between type IV collagenase secretion and metastases was studied using our new genetic system...

    At time of diagnosis, 10 to 25% of patients with colorectal cancer present synchronous liver metastases. The treatment of such patients remains controversial without any evidence based organization. Therapeutic sequences are discussed including chemotherapy, colorectal surgery, liver resection and even radio-chemotherapy for some rectal cancers. In case of resectable liver metastases, preoperative chemotherapy offers the advantage of earlier treatment of micro-metastases as well as evaluation of tumor responsiveness, which can help shape future therapy. In this setting, different surgical strategies can be chosen (classical staged procedures with colorectal surgery followed by liver surgery, simultaneous resections or liver first approach) depending on the importance of the primary and metastatic tumors. The literature remains limited, but the results of these strategies seem identical in term of postoperative morbidity and long-term survival. Staged procedures are preferred in case of major liver resection. Location of the primary tumor on the low or mid rectum will necessitate preoperative long course chemoradiotherapy and a more complex multidisciplinary organization. For patients with extensive liver metastases, non-resectability must be assessed by experienced surgeon and radiologist before treatment and during chemotherapy. In this group of patients, improved chemotherapy regimen associated with targeted therapies and new surgical strategies (portal vein embolization, ablation, staged hepatectomies…) have improved resection rate (15 to 30-40%) and long-term survival. Treatment organization for the primary tumor remains controversial. Resection of the primary to manage symptoms such as obstruction, perforation or bleeding is advocated. For patients with asymptomatic primary a non-surgical approach permits to begin rapidly chemotherapy and obtain a better control of the disease. On the other hand, initial resection of the primary may avoid complications and

    The aim of the present study was to analyse magnetic resonance findings of intramuscular metastases (IM) in a relatively large series. From January 2000 to January 2010, 28 patients (207 metastases) were retrospectively identified in the radiological database of the Martin-Luther-University. Several different scanning protocols were used depending on the localisation of IM. In 12 patients diffusion-weighted (DW) images were obtained with a multi-shot SE-EPI sequence. Apparent diffusion coefficient (ADC) maps were also calculated. Furthermore, fusion images were manually generated between the DW and half-Fourier acquisition single-shot turbo spin echo (HASTE) images. On T2-weighted images, 97% of the recognised IM were hyperintense in comparison to unaffected musculature, and 3% were mixed iso- to hyperintense. On T1-weighted images most IM (91%) were homogeneously isointense in comparison to muscle tissue, whereas 4% were hypointense, and 5% lightly hyperintense. ADC maps were calculated for 91 metastases ranging from 0.99 to 4.00 mm{sup 2}s{sup -1} (mean value 1.99 {+-} 0.66). ADC values of low (<1.5) signal intensity (SI) were identified in 26%, moderate SI (from 1.5 to 3.0) in 68%, and high SI (>3.0) in 6%. Of the IM that were investigated with contrast medium, 88.5% showed marked enhancement. It was homogeneous in 88% and heterogenous in 6%. Rim enhancement with central low attenuation was seen in 6%. There was no difference in enhancement characteristics with respect to ADC values or fusion patterns. Peritumoral enhancement was identified in 2.4%. Magnetic resonance features of muscle metastases are relatively typical and consist of round or oval intramuscular masses with well-defined margins, marked enhancement, low or moderate ADC values, and moderate to high signal intensity on fusion images.

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

    The ability of tumor cells to invade into the surrounding tissue is linked to defective adhesive and mechanical properties of the cells, which are regulated by cell surface adhesions and the intracellular filamentous cytoskeleton, respectively. With the aim to further reveal the underlying mechanisms and provide new strategies for early cancer diagnostics, we have used ultrahigh resolution stimulated emission depletion (STED) microscopy as a means to identify metastasizing cells, based on their subcellular protein distribution patterns reflecting their specific adhesive and mechanical properties. We have compared the spatial distribution of cell-matrix adhesion sites and the vimentin filamentous systems in a matched pair of primary, normal, and metastatic human fibroblast cells. We found that the metastatic cells showed significantly increased densities and more homogenous distributions of nanoscale adhesion-related particles. Moreover, they showed an increase in the number but reduced sizes of the areas of cell-matrix adhesion complexes. The organization of the vimentin intermediate filaments was also found to be significantly different in the metastasizing cells, showing an increased entanglement and loss of directionality. Image analysis procedures were established, allowing an objective detection and characterization of these features and distinction of metastatic cells from their normal counterparts. In conclusion, our results suggest that STED microscopy provides a novel tool to identify metastasizing cells from a very sparse number of cells, based on the altered spatial distribution of the cell-matrix adhesions and intermediate filaments.

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

    The liver is the most common site for colorectal cancer (CRC) metastases. Radioembolization with yttrium-90 (Y90) represents an alternative approach in the management of unresectable hepatic colorectal metastases. The objective of this study was to evaluate outcomes after treatment with Y90. A retrospective review of patients undergoing Y90 glass microsphere treatment for metastatic CRC from 2009 to 2013 was conducted. Multivariable analysis (MVA) of factors related to overall survival (OS) was performed using the Cox proportional hazard and OS estimates were calculated using the Kaplan-Meier method. We identified 68 patients. Median and 2-year OS were 11.6 months and 34%. For patients with ≤ 25% hepatic burden of disease (HBD) and 1 chemotherapy regimen, 2-year OS was 63%. Median and 2-year OS for patients with ≤ 25% versus > 25% HBD were 19.6 months and 42% versus 3.4 months and 0% (P 25% HBD, ≥ 3 lines of chemotherapy, and higher CEA were independently prognostic for increased mortality, and resected status of the primary tumor was associated with decreased mortality. The presence of extrahepatic metastases was not prognostic. Toxicities were mild and only 5 patients experienced Grade 3/4 biochemical toxicity. Yttrium-90 was associated with acceptable OS with minimal morbidity in this series. Minimal exposure to chemotherapy and low HBD were found to be associated with better OS, however, even patients with chemotherapy-refractory disease received a benefit from treatment.

    This paper evaluates the accuracy of a fast, automatic three-dimensional (3D) technique in locating hepatic metastases to the Couinaud segments. Ten patients (32 metastases) were studied before surgery by CT during arterial portography (CTAP). After automatic mapping of high-attenuation venous structures and low-attenuation metastases only, a 3D reconstruction was obtained. Couinaud's lever description is based on the distribution of the hepatic venous structures. Three-dimensional reconstruction of those structures is sufficient to locate hepatic metastases. CTAP detected 30 metastases (93.8%). After 3D reconstruction, cranial to caudal views allowed an accurate localization to specific Couinaud sections in 30 cases (100%). Front views permitted location of 29 to 30 metastases (96.7%) above or below the transverse scissura that separates superior from inferior segments of a same section

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

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

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

    Aim. The purpose of the present study was to characterize the morphological features of thymoma metastases in lymph nodes and to evaluate the possibility of their subtyping according to the 2004 WHO classification of thymus tumors. Materials and Methods. We reviewed 210 thymoma cases in our series of thymic epithelial tumors (TET), including their recurrences and lymphogenous metastases. Three cases of lymph node metastases, one case occurring synchronously with the primary tumor and one synchronously with the first relapse (both in intrathoracic location) and one case of metastasis observed in a laterocervical lymph node subsequently to two thymoma relapses were found. Results. The metastatic nodes were variably but extensively involved in all cases. The histological features were similar in both primary tumors and metastases. Thymoma metastases were subtyped according to the WHO classification as B3 (one case) and B2 (two cases), and distinctive features in comparison to metastatic epithelial neoplasias from other sites were observed. Conclusion. Thymoma lymph node metastases, although rare, can be subtyped according to the WHO classification on the basis of their morphological and immunohistochemical features. Clinically, the presence of nodal metastases may herald subsequent relapses and further metastases even in extrathoracic sites. PMID:25105128

    Brain metastasis from epithelial ovarian cancer is uncommon. We studied the presentation, treatment, and prognosis of brain metastasis in a single institution. A retrospective review of clinical details kept in the computer database of gynecologic oncology services in a tertiary institution between 1993 and 2003 was done. A Medline search for English publications on brain metastasis from epithelial ovarian cancer was performed from 1966 to 2003. The study period included 605 patients, and 4 (0.66%) patients developed brain metastases. The patients were usually well, until they presented with hemiparesis. The median primary treatment to brain metastasis interval was 16.5 months. Three out of four cases had multiple brain metastases, and all had small-volume extracranial tumor relapses. Serum CA125 measurement was not reliable in the screening for brain metastasis. The median survival after brain metastasis was 19.5 months. Single brain metastasis can be treated with surgery. Our experience supports the prevalent published opinion that all other cases should be considered for combined radiotherapy and surgery or radiotherapy and chemotherapy. Surveillance of tumor recurrence with serum CA125 monitoring does not predict brain metastasis, which carries a poor prognosis. The best mode of management of these patients is yet to be determined. Large study with multicenter participation to establish the standard treatment is urgently needed.

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

    Full Text Available Abstract Background Metastases to the stomach from an extra-gastric neoplasm are an unusual event, identified in less than 2% of cancer patients at autopsy. The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung, or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy. Methods/Results The first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage. The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent biopsy of "gastric polyps". The third is an 85-year-old man with no known history of malignancy who presented for evaluation of iron deficiency anemia by endoscopy in February 2006. Biopsies of the colonic and gastric mucosa demonstrated moderately differentiated invasive colonic adenocarcinoma with metastatic deposits in the stomach. Conclusion While the accurate recognition of these lesions at endoscopy is fraught with difficulty, pathological awareness of such uncommon metastases in the gastric mucosa is essential for accurate diagnosis and optimal patient management.

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

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

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

    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

    Differentiating melanoma metastasis from benign cutaneous lesions currently requires biopsy or costly imaging, such as positron emission tomography scans. Melanoma metastases have been observed to be subjectively warmer than similarly appearing benign lesions. We hypothesized that infrared (IR) thermography would be sensitive and specific in differentiating palpable melanoma metastases from benign lesions. Seventy-four patients (36 females and 38 males) had 251 palpable lesions imaged for this pilot study. Diagnosis was determined using pathologic confirmation or clinical diagnosis. Lesions were divided into size strata for analysis: 0-5, >5-15, >15-30, and >30 mm. Images were scored on a scale from -1 (colder than the surrounding tissue) to +3 (significantly hotter than the surrounding tissue). Sensitivity and specificity were calculated for each stratum. Logistical challenges were scored. IR imaging was able to determine the malignancy of small (0-5 mm) lesions with a sensitivity of 39% and specificity of 100%. For lesions >5-15 mm, sensitivity was 58% and specificity 98%. For lesions >15-30 mm, sensitivity was 95% and specificity 100%, and for lesions >30 mm, sensitivity was 78% and specificity 89%. The positive predictive value was 88%-100% across all strata, and the negative predictive value was 95% for >15-30 mm lesions and 80% for >30 mm lesions. Malignant lesions >15 mm were differentiated from benign lesions with excellent sensitivity and specificity. IR imaging was well tolerated and feasible in a clinic setting. This pilot study shows promise in the use of thermography for the diagnosis of malignant melanoma with further potential as a noninvasive tool to follow tumor responses to systemic therapies.

    Purpose: Based on reports of safety and efficacy, stereotactic body radiotherapy (SBRT) for treatment of malignant spinal tumors was initiated at our institution. We report prospective results of this population at Mayo Clinic. Materials and Methods: Between April 2008 and December 2010, 85 lesions in 66 patients were treated with SBRT for spinal metastases. Twenty-two lesions (25.8%) were treated for recurrence after prior radiotherapy (RT). The mean age of patients was 56.8 ± 13.4 years. Patients were treated to a median dose of 24 Gy (range, 10–40 Gy) in a median of three fractions (range, 1–5). Radiation was delivered with intensity-modulated radiotherapy (IMRT) and prescribed to cover 80% of the planning target volume (PTV) with organs at risk such as the spinal cord taking priority over PTV coverage. Results: Tumor sites included 48, 22, 12, and 3 in the thoracic, lumbar, cervical, and sacral spine, respectively. The mean actuarial survival at 12 months was 52.2%. A total of 7 patients had both local and marginal failure, 1 patient experienced marginal but not local failure, and 1 patient had local failure only. Actuarial local control at 1 year was 83.3% and 91.2% in patients with and without prior RT. The median dose delivered to patients who experienced local/marginal failure was 24 Gy (range, 18–30 Gy) in a median of three fractions (range, 1–5). No cases of Grade 4 toxicity were reported. In 1 of 2 patients experiencing Grade 3 toxicity, SBRT was given after previous radiation. Conclusion: The results indicate SBRT to be an effective measure to achieve local control in spinal metastases. Toxicity of treatment was rare, including those previously irradiated. Our results appear comparable to previous reports analyzing spine SBRT. Further research is needed to determine optimum dose and fractionation to further improve local control and prevent toxicity.

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

    Brain metastases affect 37% of patients suffering from metastatic melanoma, and their prognosis remains poor, with an overall survival lower than six months. At the moment, there is no standard therapeutic strategy for management of melanoma brain metastases. In some cases, having recourse to a systemic treatment is justified, for example, when brain metastases are combined with a progressive peripheral disease, or with unresecable brain lesions. In France, the use of fotemustine, which received the AMM approval, for metastatic melanoma treatment, is one of the treatments recommended in the case of brain metastases as this chemotherapy, that is active on the melanoma passes the blood-brain barrier. Temozolomide also shows some activity in the brain metastases treatment of melanoma that remains modest in monotherapy but seems interesting when it is combined with radiotherapy. The place of new drugs, in particular ipilimumab and vemurafenib, in the strategy of melanoma brain metastases treatment, still has to be defined and may improve the prognosis of these patients and their quality of life. The new targeted therapies, the widespread use of stereotactic radiosurgery and the improvement in neurosurgical operations would need a prospective clinical assessment, all the more so, in most of clinical studies, the presence of metastases is an exclusion criterion.

    This review aims to highlight the novel therapeutic agents in the management of brain metastases which are in various stages of clinical development. We review the results from recent clinical trials, publications and presentations at recent national and international conferences. Several new systemic treatment options for brain metastases are in early or advanced clinical trials. These drugs have good intracranial and extracranial activities. As lung cancer, breast cancer, and melanoma are the three most common causes of brain metastases, most agents in clinical development are focused on these tumor types. Several of these therapies are small molecule tyrosine kinase inhibitors or monoclonal antibodies against the tyrosine kinase receptors. Another exciting development in brain metastases management is the use of immunotherapy agents. The anti-CTLA-4 and\\or anti-PD-1 antibodies have shown promising intracranial activity in melanoma and nonsmall cell lung cancer patients with brain metastases. Contemporary clinical trials have shown encouraging intracranial activity of newer tyrosine kinase inhibitors, monoclonal antibodies against tyrosine kinase receptors and immunotherapy agents in select group of patients with brain metastases. Further studies are needed to develop therapeutic strategies, in order to improve survival in patients with brain metastases.

    1998-01-01

    To evaluate the effectiveness of radiosurgery without whole brain radiotherapy in the palliative treatment of melanoma brain metastases, we retrospectively assessed the results in 35 patients: 4 with a solitary brain metastasis, 13 with a single brain metastasis and metastases elsewhere and 18 with multiple brain metastases. The local control rate was 98.2% (55/56 metastases) at 3 months. Median survival was 22 months in patients with a solitary brain metastasis, 7.5 months in patients with a single brain metastasis and metastases elsewhere, and 4 months in patients with multiple brain metastases. Complications were unusual and surgery was required in 2 of 35 patients. These results show for the first time that melanoma patients with a unique brain metastasis with or without metastases elsewhere clearly benefit from tumour control easily obtained by radiosurgery. Although the comparison of radiosurgery with surgery and/or whole brain radiotherapy cannot be adequately addressed, radiosurgery alone seems to provide similar results with lower morbidity and impact on quality of life.

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

    In metastatic colorectal cancers, tumor cells are disseminated prior to surgical resection of the primary tumor but remain dormant until proper colonization mechanisms are activated. To identify the colonization mechanisms of the metastatic tumors, we conducted a pairwise comparison between primary colorectal cancers and metastatic tumors (n=12 pairs), including six hepatic pairs and six pulmonary pairs. The mRNA levels of 224 genes previously reported to be associated with metastasis, cytokines and angiogenesis were quantitatively determined by PCR arrays. Among them, 27 genes were duplicated or triplicated to show consistent expression. Unsupervised hierarchical clustering of the Ct values of metastasis-related genes revealed that liver metastases were indistinguishable from primary colorectal cancers (n=5/6), whereas lung metastases were highly diversified from one another and from the primary tumors (n=6/6). Cytokines and receptor gene expression array data also confirmed the divergence of pulmonary metastases from primary colorectal cancers (n=6/6). Heat map analyses of ΔCt values of the metastasis-related genes identified a 17-gene tropism signature that was sufficient not only to distinguish liver and the lung metastases, but also reconstituted the clustering of primary tumors with the hepatic metastases (n=17/18). In this pilot experiment, pulmonary metastases were significantly diverged from hepatic metastases that were indistinguishable from primary colorectal cancers. Further genomic and clinical studies are in progress to evaluate the potential of the tropism signature as a therapeutic target to inhibit the colonization of metastatic colorectal cancers.

    This paper describes the imaging features of ovarian metastases from adenocarcinoma of the colon in adolescent females. We reviewed retrospectively abdominal and pelvic computed tomographic and pelvic ultrasound examinations, histologic slices, and clinical charts of six adolescent females with ovarian metastases secondary to adenocarcinoma of the colon. One patient had ovarian metastasis at presentation and was presumed to have a primary ovarian tumor. The ovarian metastases were either solid (n = 3), complex with both solid and cystic components (n = 2), or multilocular cysts (n = 1). The ovarian lesions were large, ranging from 6 cm to 18 cm in diameter. Colorectal carcinoma in adolescent females is frequently associated with ovarian metastases. One imaging characteristic differs in adult and adolescent ovarian metastases, although they do have features in common: in adolescents, a smaller proportion of colorectal ovarian metastases are multicystic (17%) compared with the adult series (45%). These lesions are frequently large and may be complex, multicystic, or solid. Although it is a rare disease, the differential dignosis of adnexal masses in adolescent females should include ovarian metastases from adenocarcinoma of the colon. (orig.)

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

    Full Text Available Salivary duct carcinoma is a rare and highly aggressive malignant neoplasm that frequently metastasises to other organs, but cutaneous metastasis is uncommon. There are only 6 cases reported in the literature with metastases to the skin and in all cases the tumour originates from the parotid gland. We present a case of skin metastases from the submandibular gland that was mistaken for basal cell carcinoma. To the best of our knowledge, this is the first reported case of salivary duct carcinoma arising from the submandibular gland with cutaneous metastases.

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

    Improvements in survival and quality of life of patients with lung cancer had been achieved due to the progression of early diagnosis and precision medicine at recent years, however, until now, treatments targeted at lesions in central nervous system are far from satisfying, thus threatening livelihood of patients involved. After all, in the issue of prophylaxis and therapeutics of brain metastases, it is crucial to learn about the biological behavior of tumor cells in brain metastases and its mechanism underlying, and the hypothesis "seed and soil", that is, tumor cells would generate series of adaptive changes to fit in the new environment, is liable to help explain this process well. In this assay, we reviewed documents concerning tumor cells, brain micro-environments and their interactions in brain metastases, aiming to provide novel insight into the treatments of brain metastases.

  4. MR-guided percutaneous cryotherapy of liver metastases

    2001-01-01

    The prognosis for patients with liver metastases depends on the therapeutic options regarding the treatment of the primary tumor, co-existing extrahepatic metastases and the extent and treatment possibilities of the hepatic metastases themselves. Numerous curative or palliative oncological therapeutic concepts have been introduced in case of non-resectable liver metastases to prolong survival while maintaining a highest possible quality of life. Cryotherapy, which can be performed percutaneously and under magnetic resonance guidance, is one of these manifold therapeutic modalities, combining the inherent advantages of MRI with minimal invasiveness. Excellent visualization of the frozen liver tissue, precise tumor ablation, as well as an almost painless intervention due to the analgetic effect of the ice are implicating percutaneous cryotherapy as an attractive alternative to other ablation techniques. First clinical results are promising. However, meticulous and extensive long-term evaluation on a broad clinical scale is required. (orig.) [de

    Metastases of dedifferentiated sarcoma usually contain a dedifferentiated component. We report a rare case of dedifferentiated parosteal osteosarcoma (dd-POS) with well-differentiated multiple metastases in a 65-year-old woman with a painful firm mass on her thigh. Radiological examination revealed that the mass arose from the surface of her femur without medullary involvement. Multiple intramuscular metastases were detected in her lower leg on MR imaging. Small subcutaneous palpable masses were identified on her left lower leg, buttock, chest wall and head. An open biopsy and above-the-knee amputation were performed, and the mass on her femur was diagnosed as a dd-POS. However, histological examination on the subcutaneous lesions in her lower leg, buttock and head showed low-grade conventional POS without dedifferentiated components. To the best of our knowledge, this is the first report of a dd-POS with multiple metastases that do not contain any dedifferentiated components. (orig.)

    The incidence of colorectal cancer in the United States is increasing. Because more than half of patients with colorectal cancer have liver metastases develop, the number of patients with hepatic metastases also is increasing. Unfortunately, metastatic disease will be limited to the liver in perhaps 25% of these patients and confined to only one lobe of the liver 25% of this subgroup. Consequently, solitary or unilobar colorectal metastases are found in as few as 5% of patients with colorectal cancer. The median survival of patients with unresected hepatic metastases is approximately 10.6 months. Patients with solitary lesions or small tumor burdens may attain a median survival of 16-20 months, but 5-year survivors are extremely rare. In contrast, rates of 5-year survival average approximately 36% after resections of solitary hepatic lesions and may approach the same level in selected patients with multiple lesions. Factors that appear to adversely effect survival include detection of metastatic disease because of signs or symptoms of disease, an elevated carcinoembryonic antigen (CEA) level, elevated liver function tests, poorly differentiated primary lesions, lymph node-positive primary lesions, extrahepatic sites of metastases, more than four hepatic lesions, bilobar disease, a satellite pattern of metastases in the liver, positive margins of the liver resection, positive extrahepatic lymph nodes, and more than 10 units of blood transfusion during the perioperative period. Operative mortality for liver resections should remain approximately 4%, and major morbidity should be in the range of 20-30%. Modalities other than surgical resection have not improved survival in patients with colorectal hepatic metastases. Thus, when feasible, patients with metastatic colorectal cancer limited to one lobe of the liver should undergo hepatic resection. Unfortunately, only approximately 5% of patients with colorectal cancer fall into this category, so resection of hepatic

    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)

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

    Ex-situ BNCT for multifocal unresectable liver metastases employing whole or partial autograft techniques requires knowledge of boron concentrations in healthy liver and metastases following perfusion and immersion in Wisconsin solution (W), the procedure employed for organ preservation during ex-situ irradiation. Measurements of boron concentration in blood, liver and metastases following an intravenous infusion of BPA-F in five colorectal liver metastases patients scheduled for surgery were performed. Tissue samples were evaluated for boron content pre and post perfusion and immersion in W. Complementary histological studies were performed. The data showed a dose-dependent BPA uptake in liver, a boron concentration ratio liver/blood close to 1 and a wide spread in the metastases/liver concentration ratios in the range 0.8-3.6, partially attributable to histological variations between samples. Based on the boron concentrations and dose considerations (liver or =40 Gy-Eq) at the RA-3 thermal neutron facility (mean flux of about (6+/-1) x 10(9) n cm(-2)s(-1)), ex-situ treatment of liver metastases at RA-3 would be feasible.

    Breast metastases from extramammary malignancies are uncommon. The most common sources are lymphomas/leukemias and melanomas. Some of the less common sources include carcinomas of the lung, ovary, and stomach, and infrequently, carcinoid tumors, hypernephromas, carcinomas of the liver, tonsil, pleura, pancreas, cervix, perineum, endometrium and bladder. Breast metastases from extramammary malignancies have both hematogenous and lymphatic routes. According to their routes, there are common radiological features of metastatic diseases of the breast, but the features are not specific for metastases. Typical ultrasound (US) features of hematogenous metastases include single or multiple, round to oval shaped, well-circumscribed hypoechoic masses without spiculations, calcifications, or architectural distortion; these masses are commonly located superficially in subcutaneous tissue or immediately adjacent to the breast parenchyma that is relatively rich in blood supply. Typical US features of lymphatic breast metastases include diffusely and heterogeneously increased echogenicities in subcutaneous fat and glandular tissue and a thick trabecular pattern with secondary skin thickening, lymphedema, and lymph node enlargement. However, lesions show variable US features in some cases, and differentiation of these lesions from primary breast cancer or from benign lesions is difficult. In this review, we demonstrate various US appearances of breast metastases from extramammary malignancies as typical and atypical features, based on the results of US and other imaging studies performed at our institution. Awareness of the typical and atypical imaging features of these lesions may be helpful to diagnose metastatic lesions of the breast

    The aim of this study was to report our centre's experience over the past 15 years with patients with lung carcinoma and adrenal metastases treated sequentially with lung resection and adrenalectomy. We analysed a retrospective series of 19 patients who underwent adrenalectomy for lung carcinoma metastasis. All patients were operated on at the same centre, between October 2000 and October 2015. We performed a descriptive analysis and an overall survival and disease-free survival analysis. The study included 13 men and 6 women. The most common primary lung tumour was adenocarcinoma, 87.5% of which were G3. In 7 patients, the adrenal metastasis was detected synchronously, and in 12 patients it was detected metachronously. The median size of the metastasis was 63mm. Twenty-one percent of the cases presented local recurrence, and 79% presented distant metastasis. The median DFS was 21.5 months, while the DFS at 5 years was calculated at 58.33%. The median overall survival was 37.3 months, while survival at 5 years was calculated at 42.86%. None of the prognostic factors evaluated were statistically significant. Adrenalectomy in cases of isolated lung carcinoma metastasis can offer increased overall survival. Age and the degree of differentiation of the primary lung carcinoma are the factors that most influence poorer survival. Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U.

    Thyroid metastases (TM) are uncommon. Dependent on study design, the reported frequency of TM is in the range of 0.1-6% in different analyses. While clinical and histopathological features of TM were well described in the literature, radiological publications consist predominantly of isolated case reports or small series. To estimate the prevalence, clinical signs, and radiological appearances of TM. From 1997 to 2013, a total of 8849 patients with various disorders of the thyroid gland were treated in our institution. In 33 patients TM were diagnosed. Ultrasound (US) images were available in all patients, computed tomography (CT) of the neck in 16 patients, and magnetic resonance imaging (MRI) in nine patients. Clinically, most patients (85%) presented with a painless neck mass. Primary tumors were renal cell carcinoma (79%), colorectal cancer (12%), lung cancer (3%), rhabdomyosarcoma (3%), and breast carcinoma (3%). On US, most lesions were irregular in shape with inhomogenous texture. On CT, all TM were hypodense. On T1-weighted images, most TM were inhomogenously iso-to-hyperintense in comparison to the normal thyroid tissue, and slightly hyperintense on T2-weighted images with an inhomogenous contrast enhancement. The prevalence of TM was 0.4%. Most of the TM originated from renal cell carcinoma. The identified radiological features of TM should be taken into consideration in the differential diagnosis of thyroid lesions. © The Foundation Acta Radiologica 2015.

    Metastases to the thyroid gland from renal cancer pose a challenge to physicians, due in part to the rarity of the phenomenon, the prolonged time interval between removal of the primary renal cancer and the appearance of metastases, the difficulty in diagnosis, and the uncertainty regarding long-term prognosis. We report our experience with diagnosis and management of patients affected by thyroid metastases from renal clear cell carcinoma. We report herein three clinical cases of thyroid metastases from renal clear cell carcinoma. We also present a review of the literature and examine common features of clinical presentation and management recommendations. Over the past 17 years, 918 patients underewent surgery for thyroid cancer in our institution. Histological examination demonstrated a thyroid secondary malignancy from kidney cancer in 3 cases. Two patients underwent total thyroidectomy, whereas in the third patient a palliative right lobectomy with homolateral latero-cervical lymphoadenectomy was performed. At a 5-year follow-up, only one patient survived and was disease-free. Thyroid metastases from renal clear cell carcinoma are a rare occurrence but should be taken into consideration in the differential diagnosis of a thyroid nodule. Preoperative diagnosis is often difficult. Nevertheless, an extensive diagnostic workup is recommended because the subsequent therapy must be tailored on the basis of the local extension of metastases. Surgical treatment of solitary thyroid metastases is recommended. However, patients with disseminated disease have a poor prognosis, and palliative care is the indicated recommendation. In these patients and in surgically untreatable patients, prolonged survival may be achieved by adjuvant medical therapy.

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

    Examination for liver and bone metastases was performed in 30 women suffering from carcinoma of the uterus and in 27 with cervical and 37 with ovarian carcinoma. Scintigraphy was the examination method of choice in bone metastases and computed tomography in liver metastases.

    Full Text Available Objective: to evaluate the impact of cytoreductive surgery on treatment results in patients with colorectal cancer and synchronous lung metastases.Materials and methods. This retrospective investigation analyzed the results of therapy in patients with colorectal cancer and synchronous lung metastases who had been treated in the period 2000 to 2012. The investigators studied the following indicators: the impact of cytoreductive surgery on the survival of patients with this condition, the clinical characteristics of a group of patients with isolated lung involvement, the dissimilarity of this group from a group of patients with extrapulmonary metastases, the possibility of performing complete cytoreductive surgery in patients with varying degrees of a metastatic process, and the number of patients with complications in primary tumor.Results. The investigations included the data of 112 patients with colorectal cancer and synchronous lung metastases. Out of them, 38 (33.9 % patients had isolated lung involvement and the latter was associated with extrapulmonary metastases in 74 (64.1 %. In 16 of the 38 patients, isolated lung metastases were regarded as resectable and complete cytoreductive surgeries were performed. The median follow-up in the examined group was 15.2 months. One- and two-year overall survival rates were 63 and 45 %, respectively. The patients with isolated lung metastases were observed to have higher 2-year overall survival rates than those with multiple metastases (63.0 and 37.5 %, respectively; p = 0.055 and there were significantly higher 2-year overall survival rates in patients after removal of primary tumors than in those who had not undergone cytoreductive surgery (21.0 and 52.5 %, respectively; p = 0.004. Two-year overall survival rates were 72.5 % in the complete cytoreductive treatment group.Conclusion. The prognosis in the patients with colorectal cancer and synchronous lung metastases was better than that in those with

    Full Text Available Electrochemotherapy of colorectal liver metastases has been proven to be feasible, safe and effective in a phase I/II study. In that study, a specific group of patients underwent two-stage operation, and the detailed histopathological evaluation of the resected tumors is presented here. Regressive changes in electrochemotherapy-treated liver metastases were evaluated after the second operation (in 8-10 weeks in 7 patients and 13 metastases when the treated metastases were resected. Macroscopic and microscopic changes were analyzed. Electrochemotherapy induced coagulation necrosis in the treated area encompassing both tumor and a narrow band of normal tissue. The area became necrotic, encapsulated in a fibrous envelope while preserving the functionality of most of the vessels larger than 5 mm in diameter and a large proportion of biliary structures, but the smaller blood vessels displayed various levels of damage. At the time of observation, 8-10 weeks after electrochemotherapy, regenerative changes were already seen in the peripheral parts of the treated area. This study demonstrates regressive changes in the whole electrochemotherapy-treated area of the liver. Further evidence of disruption of vessels less than 5 mm in diameter and preservation of the larger vessels by electrochemotherapy is provided. These findings are important because electrochemotherapy has been indicated for the therapy of metastases near major blood vessels in the liver to provide a safe approach with good antitumor efficacy.

    Prognosis for patients with brain metastasis remains poor. Whole brain radiation therapy is the conventional treatment option; it can improve neurological symptoms, prevent and improve tumor associated neurocognitive decline, and prevents death from neurologic causes. In addition to whole brain radiation therapy, stereotactic radiosurgery, neurosurgery and chemotherapy also are used in the management of brain metastases. Radiosensitizers are now currently being investigated as potential treatment options. All of these treatment modalities carry a risk of central nervous system (CNS) toxicity that can lead to neurocognitive impairment in long term survivors. Neuropsychological testing and biomarkers are potential ways of measuring and better understanding CNS toxicity. These tools may help optimize current therapies and develop new treatments for these patients. This article will review the current management of brain metastases, summarize the data on the CNS effects associated with brain metastases and whole brain radiation therapy in these patients, discuss the use of neuropsychological tests as outcome measures in clinical trials evaluating treatments for brain metastases, and give an overview of the potential of biomarker development in brain metastases research

  10. AKT1 Activation Promotes Development of Melanoma Metastases

    Full Text Available Metastases are the major cause of melanoma-related mortality. Previous studies implicating aberrant AKT signaling in human melanoma metastases led us to evaluate the effect of activated AKT1 expression in non-metastatic BRAFV600E/Cdkn2aNull mouse melanomas in vivo. Expression of activated AKT1 resulted in highly metastatic melanomas with lung and brain metastases in 67% and 17% of our mice, respectively. Silencing of PTEN in BRAFV600E/Cdkn2aNull melanomas cooperated with activated AKT1, resulting in decreased tumor latency and the development of lung and brain metastases in nearly 80% of tumor-bearing mice. These data demonstrate that AKT1 activation is sufficient to elicit lung and brain metastases in this context and reveal that activation of AKT1 is distinct from PTEN silencing in metastatic melanoma progression. These findings advance our knowledge of the mechanisms driving melanoma metastasis and may provide valuable insights for clinical management of this disease.

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

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

    We studied the clinicopathological features of type AB thymoma with liver metastases and explore the histological types, diagnosis and differential diagnosis, treatment and prognosis for this disease. Liver metastasis specimens were derived from one case of type AB thymoma 5 years after operation and were examined histologically using light microscopy and immunohistochemistry. A comprehensive analysis was performed on the patient's clinical manifestations, histopathology, immunohistochemistry features, differential diagnosis, treatment and prognosis in combination with a review of the relevant literature. Metastases were detected 5 years after initial operation on a 49-year-old, female patient with type AB thymoma. The pathological diagnosis for the liver metastases was type AB thymoma. Immunohistochemistry staining showed CKpan (+), CD3 (+), CD2 (+), TdT (+), CD5 (+), P53 (+), Hep-1 (-), and Ki67-positive cells (25%). The expression level of galectin-3 was higher than in the mediastinal thymoma tissue identified 5 years prior. Liver metastases of type AB thymoma are extremely rare. This case indicated that type AB thymoma with low malignant potential might recur and develop distant metastases. Overexpression of p53, galectin-3 and Ki67 in type AB thymoma might coordinately manipulate the process of development, progression and malignant transformation of type AB thymomas.

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

    To assess the clinical value of treatment with 131 I for brain metastases from differentiated thyroid cancer (DTC), the authors have observed 8 cases of brain metastases from DTC who received follow-up after 131 I therapy (2 male, 6 female, aged 12-65 years). The results of 131 I therapy were evaluated with clinical presentation, imaging scan and survival analysis. The main results are as follows. (1) All cases had been survival for 2-35 years in follow-up. (2) A space-occupying lesion in right cerebellum was reduced after taking 20.65 GBq and disappeared after 23.61 GBq, demonstrated by computed tomography. (3) The sequences and doses of 131 I therapy were clearly decreased for the cases with total thyroidectomy in comparison with those with semithyroidectomy (p 131 I for brain metastases from DTC after undergoing thyroidectomy may improve clinical symptoms and lift quality, reduce lesions, and prolong survival.

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

    1999-01-01

    Purpose: Because whole brain radiotherapy (WBRT) may cause dementia in long-term survivors, selected patients with brain metastases may benefit from initial treatment with radiosurgery (RS) alone reserving WBRT for salvage as needed. We reviewed results of RS ± WBRT in patients with newly diagnosed brain metastasis to provide background for a prospective trial. Methods and Materials: Patients with single or multiple brain metastases managed initially with RS alone vs. RS + WBRT (62 vs. 43 patients) from 1991 through February 1997 were retrospectively reviewed. The use of upfront WBRT depended on physician preference and referral patterns. Survival, freedom from progression (FFP) endpoints, and brain control allowing for successful salvage therapy were measured from the date of diagnosis of brain metastases. Actuarial curves were estimated using the Kaplan-Meier method. Analyses to adjust for known prognostic factors were performed using the Cox proportional hazards model (CPHM) stratified by primary site. Results: Survival and local FFP were the same for RS alone vs. RS + WBRT (median survival 11.3 vs. 11.1 months and 1-year local FFP by patient 71% vs. 79%, respectively). Brain FFP (scoring new metastases and/or local failure) was significantly worse for RS alone vs. RS + WBRT (28% vs. 69% at 1 year; CPHM adjusted p = 0.03 and hazard ratio = 0.476). However, brain control allowing for successful salvage of a first failure was not significantly different for RS alone vs. RS + WBRT (62% vs. 73% at 1 year; CPHM adjusted p = 0.56). Conclusions: The omission of WBRT in the initial management of patients treated with RS for up to 4 brain metastases does not appear to compromise survival or intracranial control allowing for salvage therapy as indicated. A randomized trial of RS vs. RS + WBRT is needed to assess survival, quality of life, and cost in good-prognosis patients with newly diagnosed brain metastases

    Full Text Available Pancreatic neuroendocrine tumor (pNET is a rare type of pancreatic tumors. The incidence of pNET shows a gradually increasing trend in recent years. The most common organ of distant metastases is the liver. Surgical resection is still the optimal treatment for resectable, well-differentiated liver metastases with no evidence of extrahepatic spread. For unresectable patients, a combination of multiple modalities, such as transarterial chemoembolization, radiofrequency ablation, systemic chemotherapy, and molecular targeted therapy, can prolong the survival time of patients. Liver transplantation should be strictly evaluated on an individual basis.

  8. Criteria for palliation of bone metastases - Clinical applications

    2008-02-01

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

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

    1996-01-01

    Purpose: Patients with newly diagnosed brain metastases generally benefit from whole brain radiation therapy (WBRT). However, the role of reirradiation for patients who develop progressive brain metastases has been controversial. This retrospective study examines our experience with reirradiation of patients for progressive brain metastases after an initial course of WBRT. Methods and Materials: From 1975-1993, 2658 patients received WBRT for brain metastases at our institution. Eighty-six patients were subsequently reirradiated for progressive brain metastases. The median age of these patients was 58 (range: 31-81). The most common primary sites were breast and lung. Fifty patients had metastatic disease at other sites. Most patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 2 (40 patients) or 3 (38 patients). The median dose of the first course of irradiation was 30 Gy (range: 1.5-50.6 Gy). The median dose of the second course of irradiation was 20 Gy (range: 8.0-30.6 Gy). Results: Twenty-three patients (27%) had resolution of neurologic symptoms, 37 patients (43%) had partial improvement of neurologic symptoms, and 25 patients (29%) had either no change or worsened after reirradiation. The median survival following reirradiation was 4 months (range: 0.25-72 months). The majority of patients had no significant toxicity secondary to reirradiation. Five patients had radiographic abnormalities of their brain consistent with radiation-related changes. One patient had symptoms of dementia that was thought to be caused by radiotherapy. Various potential prognostic factors were evaluated for possible associations with survival, including age, sex, primary site, ECOG performance status, RTOG neurologic functional class, absence of extracranial metastases, number of brain metastases, and dose of reirradiation. Absence of extracranial metastasis, solitary brain metastasis, and a retreatment dose > 20 Gy were associated with improved survival in

    Purpose: Patients with brain metastases generally benefit from whole brain irradiation (WBRT). However, the role of reirradiation for patients who develop progressive brain metastases after a course of WBRT has been controversial. This retrospective study examines our experience with reirradiation of patients for progressive brain metastases after an initial course of WBRT. Materials and Methods: From 1975 to 1993, 2658 patients received WBRT for brain metastases at our institutions. Eighty-six patients were subsequently reirradiated for progressive brain metastases. The median age of these patients was 58 (range: 31-81). The primary sites included breast (31 patients), lung (31 patients), colon (6 patients), melanoma (5 patients), and others (13 patients). Fifty patients had metastatic disease at other sites. Most patients had ECOG performance status of 2 (39 patients) or 3 (36 patients). The median dose of the first course of irradiation was 30 Gy (range: 20-50.4 Gy). The median time interval between the first and second courses of irradiation was 7.6 months (range: 1.5-50.6 months). The median dose of the second course of irradiation was 20 Gy (range: 8.0 to 30.6 Gy). All except one patients were given steroids. Patients were followed until death, except for one patient who was lost to follow-up and one long-term surviver who was followed for 72 months. Results: Twenty-three patients (27%) had complete resolution of neurologic symptoms, 37 patients (43%) had partial improvement of neurologic symptoms, and 24 patients (28%) had either no subjective response or worsened after reirradiation. The RTOG neurological function class improved in 32 patients, remained unchanged in 40 patients, and deteriorated in 8 patients. Survival following reirradiation ranged from 0.25 to 72 months with a median survival of 4 months. The majority of patients had no toxicity secondary to reirradiation. Five patients had radiographic abnormalities of their brains consistent with

    Background and purpose: there is no evidence in the literature about the incidence of synchronous brain metastases in patients with choroidal metastases. This is of major importance, because the radiation fields of choroidal metastases and, later on, brain metastases, if treated consecutively, are partly overlapping, thus potentially increasing the rate of late side effects such as brain necrosis. The goal of this study was to determine the frequency of synchronous brain metastases. Patients and methods: 50 patients with choroidal metastases were enrolled into a study of the ''Arbeitsgemeinschaft Radiologische Onkologie'' of the German Cancer Society (ARO 95-08) with standardized 40 Gy radiotherapy, 2 Gy single dose. All patients were staged before treatment with a computed tomography of the brain (CCT). No patient showed clinical signs of brain metastases. Results: 13 out of 50 patients (26%) had brain metastases in the CCT leading to radiotherapy of the brain and choroidal metastases in one volume. Conclusion: a CCT is indicated at the diagnosis of choroidal metastases for screening of synchronous brain metastases. The incidence is about 25%, and the diagnosis of brain metastases results in a different target volume: the whole brain including the posterior parts of the eyes compared to the posterior parts of the eyes alone. Therefore, the risk of late side effects could be reduced compared with an additional later radiotherapy of the whole brain with partly overlapping fields. (orig.)

    Metastastic carcinoma to extraocular muscles is extremely rare, but even more so is the case of a bilateral one. A 50-year-old woman with a history of mastectomy for a T4N1M0 right breast carcinoma was referred to us with diplopia due to bilateral extraocular muscle metastases, 5 years post mastectomy. Multiple metastases to the whole body were also present. A combination of high-dose irradiation, hormonotherapy and chemotherapy were performed. Despite the multidisciplinary treatment approach, the diplopia persisted. A literature review revealed only 4 cases of bilateral metastases to extraocular muscles. The present case is the second attributed to lobular carcinoma and the only one treated with a high dose of radiotherapy combined with systemic therapy. In a cancer patient, any orbital change must be examined for the possibility of an extraocular metastasis. Conclusions affecting the optimal treatment policy of extraocular muscle metastases are difficult to determine, due to the small number of reported cases. (c) 2008 S. Karger AG, Basel

    Tyrosine kinase inhibitors against the receptors of vascular endothelial growth factor (VEGFR), epidermal growth factor (EGFR) and the platelet derived growth factor (PDGFR) are increasingly used in the treatment of progressive cancers. However, the expression of these receptors especially in lung metastases has not been examined. Tissue specimen from 35 lung metastases of 33 patients with renal cell carcinoma (n=8), sarcoma (n=10), colorectal carcinoma (n=6), otolaryngologic carcinoma (OLC, n=4), testicular and endometrial cancer (n=1 each), malignant melanoma (n=1), adrenal cancer (n=2), malignant fibrous histiocytoma and malignant peripheral nerve sheath tumor (n=1 each) have been immunohistochemically tested for the expression of PDGFR alpha/beta, VEGFR and EGFR. None of the patients had been pretreated with angiogenic inhibitors prior to metastasectomy. PDGFRalpha was expressed in all metastases; 31% stained negative for PDGFRbeta, 86% negative for VEGFR and 45% negative for EGFR. Primary tumors revealed positive staining for PDGFRalpha in 88%, for PDGFRbeta in 59%, for VEGFR in 0% and for EGFR in 18%. Our investigation of a pilot character represents a 'biomarker-based' analysis of pulmonary metastases of different primary tumors; we conclude that an immediate 'tumor profiling' at initial diagnosis should be considered in order to guide tumor therapy individually.

  8. Actual role of radiofrequency ablation of liver metastases

    The liver is, second only to lymph nodes, the most common site for metastatic disease irrespective of the primary tumour. More than 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improved survival in patients with colorectal metastases, only approximately 20% of patients are eligible for surgery. Thermal ablation and especially radiofrequency ablation emerge as an important additional therapy modality for the treatment of liver metastases. RF ablation shows a benefit in life expectancy and may lead in a selected patient group to cure. Percutaneous RF ablation appears safer (versus cryotherapy), easier (versus laser), and more effective (versus ethanol instillation and transarterial chemoembolisation) compared with other minimally invasive procedures. RF ablation can be performed by a percutaneous, laparoscopical or laparotomic approach, and may be potentially combined with chemotherapy and surgery. At present ideal candidates have tumours with a maximum diameter less than 3.5 cm. An untreatable primary tumour or a systemic disease represents contraindications for performing local therapies. Permanent technical improvements of thermal ablation devices and a better integration of thermal ablation in the overall patient care may lead to prognosis improvement in patients with liver metastases.

    The thyroid gland is a rare site of clinically detectable tumor metastasis and kidneys are frequently the site of the parent malignancy. In the present review on thyroid metastases from renal cell carcinoma, cases were searched on PubMed by entering the strings: "renal carcinoma [or "hypernephroma"] AND thyroid metastasis/metastases". Thus, we retrieved a total of 111 cases that were published between 1964 and 2007, a total that became 113 by adding two patients observed by us. The female to male ratio was 1.35:1. The primary renal cancer was almost always unilateral (90%) (with no significant side preference) and only rarely bilateral (9% in men, 4% in women), whereas bilaterality of thyroid metastases was relatively more frequent (28%). Thyroid metastasis from renal cancer was commonly single with a unique node that appears solid and hypoechoic at ultrasonography, approximately 9 years after nephrectomy. Concordance of lateralization was insignificantly greater for the right kidney/right thyroid lobe pattern (54%) than for the left kidney/left thyroid lobe pattern (40%), regardless of gender. Finally, survival was longer for women. Thyroid metastases, even if rare in the clinical practice, must be considered in the differential diagnosis of a thyroid nodule, particularly in patients who have a history of malignancies.

    Summary: Metastases from uveal melanoma are often confined to the liver. Palliative hepatic chemoembolization has been considered to be a reasonable treatment approach. We enrolled 14 patients with hepatic metastases from uveal melanoma into a pilot trial of transarterial chemoembolization (TACE). All patients received additional systemic immuno-chemotherapy or best supportive care. In 31 procedures 100 mg/m{sup 2} of cisplatine was continuously infused by means of a power injector preceding embolization by manual injection of polyvinyl alcohol particles. In three procedures cisplatine was replaced by 200 mg/m{sup 2} carboplatine because of increased serum creatinine levels. Tumor response was evaluated using RECIST criteria. Fourteen patients received 34 TACE's (mean: 2.4 treatments). Eight patients (57%) achieved partial response (PR), four patients (29%) had stable disease and two patients (14%) tumor progression. Median time to progression was 8.5 months (5-35 months). Median survival after first TACE was 14.5 months in responders compared to 10 months in non-responders (p = 0.18, not significant) and 11.5 months (3-69 months) in all patients. In seven patients with metastases occupying less than 25% of liver volume median survival was 17 months compared to 11 months in seven patients with tumor involvement of more than 25% (p = 0.02) with partial response rate of 86% and 29%, respectively. TACE of liver metastases from uveal melanoma is well tolerated and may prolong survival in patients with limited tumor extension.

    Purpose: There is no consensus about the treatment of rectal tumour when there are synchronous metastases. The interest of radiotherapy is debated. Patients and methods: Thirty-seven patients with rectal tumour and synchronous metastases were treated with radiotherapy first between September 1994 and December 2004. We analysed the tolerance, local control, resectability, overall survival of such a therapeutic strategy. Results: The mean follow-up was 30 months. Twenty-four tumors were resectable for both the primary site and the metastases. Thirteen were unresectable at the time of diagnosis. Thirty-three patients were treated with radio chemotherapy, ten with radiotherapy alone. Eighty-six decimal five percent of them had no pelvic symptom six weeks after the treatment. Twenty-one rectal tumours were finally resected. The disease progressed in six cases during the radiotherapy. Surgery of the metastases was possible for 12 patients with tumour initially resectable. Conclusion: Radio chemotherapy is a 'tolerable' treatment, in spite of more frequent urinary or digestive side-effects. But, if there is no surgery, palliative effect of radiotherapy is limited.

    Metastases to the brain occur in 25 to 35% of patients with systemic cancer. Cerebral metastatic is the most common intracranial tumor in adults and occur up to 10 times more frequently than primary tumors in the central nervous system. Significant advances have occurred in the diagnosis and treatment of metastases to the brain, and the therapeutic nihilism of the past is now no longer warranted for most patients. With the currently available treatments, most patients do not die of their brain metastases and usually experience effective palliation of neurologic symptoms and meaning full extension of life. As a trial to limit the cerebral metastatic disease, many and diverse therapy options have been developed such as: chemotherapy, surgery plus whole-brain radiotherapy, only radiation therapy, therapy with neutron, intersticial brachytherapy and stereotactic radiosurgery. In selected cases, surgery plus whole-brain radiotherapy is the conventional treatment for single metastases. However, recurrence usually limits the quality of life and greatly decrease the patients time life, and the therapy options are scarce. This piece of writing also includes a review of the available therapy forms to manage this kind of lesions. (The author)

    Splenic metastases from solid tumors are a rare event with an incidence of only 2.9% to 9%. Splenic metastases from cervical cancer are a rare entity. Only a few cases have been reported of isolated spleen metastases from cervical cancer. We present the case of a 76-year-old woman with moderately differentiated endocervical adenocarcinoma stromal and endocervical invasion. Clinical stage was Ib1 and Ca-125 values of 150 U. She was managed with hysterectomy and pelvic lymphadenectomy. She received pelvic radiotherapy (45 Gy) followed 24 Gy of brachytherapy. Two years later she presented with abdominal pain. Abdominal computed tomography showed two splenic parenchymal lesions without disease in the remainder of the abdominal cavity and chest with a Ca-125 of 2,733 U. The patient is submitted to splenectomy. Histopathology demonstrates splenic metastases of well-differentiated adenocarcinoma from the endocervix. Immunohistochemical stain showed positivity from carcinoembryonic antigen; estrogen and progesterone receptors are negative. Ca-125 level 8 weeks after surgery was 16 U/ml. The patient received six cycles of adjuvant chemotherapy with paclitaxel and cisplatin. At 12 months follow-up the patient is alive and without evidence of tumor activity. The spleen is an uncommon site of metastasis. Splenectomy is considered the appropriate treatment in order to avoid complications such as splenic rupture and splenic vein thrombosis as well as to improve pain control from splenomegaly. Twelve months after surgery our patient is alive and without evidence of tumor activity.

    Purpose: Because whole brain radiotherapy (WBRT) carries a significant risk of dementia in long-term survivors, it is desirable to determine if some patients with brain metastases may be managed with radiosurgery (RS) alone, reserving WBRT for salvage therapy as needed. To begin to approach this problem, we retrospectively reviewed freedom from brain failure/progression (Brain FFP) and survival of patients with newly-diagnosed solitary or multiple brain metastases treated with Gamma Knife RS ± WBRT. Materials and Methods: All patients treated at our institution with Gamma Knife RS for newly-diagnosed solitary or multiple (2-8) brain metastases from September 1991 through December 1995 were reviewed. Whether or not WBRT was given depended on physician preference and referral patterns. Brain FFP was measured from the date of RS until development of a new brain metastasis or progression of a treated metastasis, with censoring at the time of the last imaging study. Survival was measured from the date of RS until death or last clinical follow-up. Actuarial curves were estimated using the Kaplan-Meier method and compared with the log rank test. Multivariate analyses to adjust for known prognostic variables (age, KPS, history of extracranial metastases, and total target volume) were performed using the Cox proportional hazards model. Results: From September 1991-December 1995, 90 patients with newly-diagnosed brain metastases underwent RS. Three patients treated palliatively to a small component of their intracranial disease were excluded, leaving 54 treated with RS alone and 33 treated with RS + WBRT. Age ranged from 31-83 years (median, 59 years), KPS from 60-100 (median, 90), and total target volume from 0.15-26.1 cm 3 (median, 5.5 cm 3 ). Fifty patients had a history of extracranial metastases. Results are shown below. In the RS alone group, (22(54)) patients (41%) had a brain failure and (20(54)) (37%) died without evidence of brain failure. In the RS + WBRT group

    Full Text Available Purpose: Melanoma is one of the most common malignancies to metastasize to the brain. Many patients with this disease will succumb to central nervous system (CNS disease, highlighting the importance of effective local treatment of brain metastases for both palliation and survival of the disease. Our objective was to evaluate the outcomes associated with stereotactic radiosurgery (SRS in the treatment of melanoma brain metastases. Materials and Methods: We retrospectively reviewed 54 patients with a total of 103 tumors treated with SRS. Twenty patients had prior surgical resection and nine patients underwent prior whole brain radiation therapy (WBRT. 71% of patients had active extracranial disease at the time of SRS. Median number of tumors treated with SRS was 1(range: 1-6 with median radiosurgery tumor volume 2.1 cm 3 (range: 0.05-59.7 cm 3 . The median dose delivered to the 80% isodose line was 24 Gy in a single fraction. Results: The median follow-up from SRS was five months (range:1-30 months. Sixty-five percent of patients had a follow-up MRI available for review. Actuarial local control at six months and 12 months was 87 and 68%, respectively. Eighty-one percent of patients developed new distant brain metastases at a median time of two months. The six-month and 12-month actuarial overall survival rates were 50 and 25%, respectively. The only significant predictor of overall survival was surgical resection prior to SRS. Post-SRS bleeding occurred in 18% of patients and at a median interval of 1.5 months. There was only one episode of radiation necrosis with no other treatment-related toxicity. Conclusion: SRS for brain metastases from melanoma is safe and achieves acceptable local control.

    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

    Purpose. To determine the efficacy of celiac plexus block during thermoablation of liver metastases. Methods. Fifty-five consecutive patients underwent thermoablation therapy of liver tumors by laser-induced thermotherapy. Twenty-nine patients received a temporary celiac plexus block, 26 patients acted as control group. In both groups fentanyl and midazolam were administered intravenously upon request of the patient. The duration of the intervention, consumption of opiates, and individual pain sensations were documented. Results. No complications resulting from the celiac plexus block were recorded. Celiac plexus block significantly reduced the amount of pain medication used during thermoablation therapy of liver tumors (with block, 2.45 μg fentanyl per kg body weight; without block, 3.58 μg fentanyl per kg body weight, p < 0.05; midazolam consumption was not reduced) in patients with metastases ≤5 mm from the liver capsule. For metastases farther away from the capsule no significant differences in opiate consumption were seen. Celiac plexus block reduced the time for thermoablation significantly (178 min versus 147 min, p < 0.05) no matter how far the metastases were from the liver capsule. Average time needed to set the block was 12 min (range 9-15 min); additional costs for the block were marginal. As expected (as pain medications were given according to individual patients' needs) pain indices did not differ significantly between the two groups. Conclusion. In patients with liver metastases ≤5 mm from the liver capsule, celiac plexus block reduces the amount of opiates necessary, simplifying patient monitoring. In addition celiac plexus block reduces intervention time, with positive effects on overall workflow for all patients

    To evaluate tumor response after treating unresectable lung metastases with transpulmonary chemoembolization (TPCE) in palliative intention. From 2001 to 2005, 52 patients (mean: 59.8 years; 32 males/20 females) suffering from 106 unresectable lung metastases (mean:6 metastases/patient; range,1-21) were treated with 2-10 TPCE-sessions (mean: 3.3 sessions/patient). Metastases originated from primaries, including colorectal carcinoma (n = 20), breast cancer (n = 6), renal cellular carcinoma (n = 5), thyroid cancer (n = 4), cholangiocellular carcinoma (n = 2), leiomyosarcoma (n = 2), and others (n = 13). Tumor-feeding pulmonary arteries were selectively probed after puncturing the femoral vein, and administering 10 ml lipiodol, mitomycin C, and microspheres (Spherex) each via balloon catheter over pulmonary approach. During therapy, follow-up was accomplished at 4-week intervals using unenhanced and contrast-enhanced CT. After sequential therapy, follow-up was performed every 3 months for a period of 6 months up to 2.25 years. All patients tolerated the treatments well without major side effects or complications. In 24% (n = 13) moderate to high lipiodol uptake was found, while 75% (n = 39) of the tumors showed a low uptake. According to the RECIST criteria, ''partial response'' was achieved in 16 cases, ''stable disease'' in 11 cases, and ''progressive disease'' in 25 cases [mean survival: 17 months/median: 21.1 months (Kaplan-Meyer)]. According to these findings, TPCE is a well-tolerated procedure for palliative treatment of unresectable lung metastases. (orig.)

    Purpose/Objective(s): Radiation therapy can be used to treat uveal metastases with the goal of local control and improvement of quality of life. Proton therapy can be used to treat uveal tumors efficiently and with expectant minimization of normal tissue injury. Here, we report the use of proton beam therapy for the management of uveal metastases. Methods and Materials: A retrospective chart review was made of all patients with uveal metastases treated at our institution with proton therapy between June 2002 and June 2012. Patient and tumor characteristics, fractionation and dose schemes, local control, and toxicities are reported. Results: Ninety patients were identified. Of those, 13 were excluded because of missing information. We report on 77 patients with 99 affected eyes with available data. Patients were 68% female, and the most common primary tumor was breast carcinoma (49%). The median age at diagnosis of uveal metastasis was 57.9 years. Serous retinal detachment was seen in 38% of treated eyes. The median follow-up time was 7.7 months. The median dose delivered to either eye was 20 Gy(relative biological effectiveness [RBE]) in 2 fractions. Local control was 94%. The median survival after diagnosis of uveal metastases was 12.3 months (95% confidence interval, 7.7-16.8). Death in all cases was secondary to systemic disease. Radiation vasculopathy, measured decreased visual acuity, or both was observed in 50% of evaluable treated eyes. The actuarial rate of radiation vasculopathy, measured decreased visual acuity, or both was 46% at 6 months and 73% at 1 year. The 6 eyes with documented local failure were successfully salvaged with retreatment. Conclusions: Proton therapy is an effective and efficient means of treating uveal metastases. Acutely, the majority of patients experience minor adverse effects. For longer-term survivors, the risk of retinal injury with vision loss increases significantly over the first year.

    Full Text Available 40-50% of patients with colorectal cancer (CRC will develop liver metastases (CRLM during the course of the disease. One third of these patients will additionally develop pulmonary metastases.137 consecutive patients with CRLM, were analyzed regarding survival data, clinical, histological data and treatment. Results were stratified according to the occurrence of pulmonary metastases and metastases resection.39% of all patients with liver resection due to CRLM developed additional lung metastases. 44% of these patients underwent subsequent pulmonary resection. Patients undergoing pulmonary metastasectomy showed a significantly better five-year survival compared to patients not qualified for curative resection (5-year survival 71.2% vs. 28.0%; p = 0.001. Interestingly, the 5-year survival of these patients was even superior to all patients with CRLM, who did not develop pulmonary metastases (77.5% vs. 63.5%; p = 0.015. Patients, whose pulmonary metastases were not resected, were more likely to redevelop liver metastases (50.0% vs 78.6%; p = 0.034. However, the rate of distant metastases did not differ between both groups (54.5 vs.53.6; p = 0.945.The occurrence of colorectal lung metastases after curative liver resection does not impact patient survival if pulmonary metastasectomy is feasible. Those patients clearly benefit from repeated resections of the liver and the lung metastases.

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

    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

    ABSTRACT: A 72-year-old man presented with a two month history of rectal bleeding. Colonoscopy demonstrated synchronous lesions at 3 cm and 40 cm with histological analysis confirming synchronous adenocarcinomata. He developed bilobar hepatic metastases while undergoing neoadjuvant chemoradiotherapy. Treatment was complicated by Fournier\\'s gangrene of the right hemiscrotum which required surgical debridement. Eight months later he re-presented with an ulcerating lesion on the right hemiscrotum. An en-bloc resection of the ulcerating scrotal lesion and underlying testis was performed. Immunohistological analysis revealed metastatic adenocarcinoma of large bowel origin. Colorectal metastasis to the urogenital tract is rare and here we report a case of rectal carcinoma metastasizing to scrotal skin.

    Full Text Available Liver metastases from colorectal cancer (CRC result in substantial morbidity and mortality. The primary treatment is systemic chemotherapy, and in selected patients, surgical resection; however, for patients who are not surgical candidates and/or fail systemic chemotherapy, liver-directed therapies are increasingly being utilized. Yttrium-90 (Y-90 microsphere therapy, also known as selective internal radiation therapy (SIRT or radioembolization, has proven to be effective in terms of extending time to progression of disease and also providing survival benefit. This review focuses on the use of Y-90 microsphere therapy in the treatment of liver metastases from CRC, including a comprehensive review of published clinical trials and prospective studies conducted thus far. We review the methodology, outcomes and side effects of Y-90 microsphere therapy for metastatic CRC

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

    Full Text Available The best clinical treatment for spinal metastases requires an integrated approach with input from an interdisciplinary cancer team. The principle goals of treatment are maintenance or improvement in neurologic function and ambulation, spinal stability, durable tumor control, and pain relief. The past decade has witnessed an explosion of new technologies that have impacted our ability to reach these goals, such as separation surgery and minimally invasive spinal procedures. The biggest advance, however, has been the evolution of stereotactic radiosurgery that has demonstrated durable tumor control both when delivered as definitive therapy and as a postoperative adjuvant even for tumors considered markedly resistant to conventional external beam radiation. In this paper, we perform an update on the management of spinal metastases demonstrating the integration of these new technologies into a decision framework NOMS that assesses four basic aspects of a patient’s spine disease: Neurologic, Oncologic, Mechanical Instability and Systemic disease.

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

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

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

    Accurate segmentation and quantification of liver metastases on CT images are critical to surgery/radiation treatment planning and therapy response assessment. To date, there are no reliable methods to perform such segmentation automatically. In this work, the authors present a method for semiautomatic delineation of liver metastases on contrast-enhanced volumetric CT images. The first step is to manually place a seed region-of-interest (ROI) in the lesion on an image. This ROI will (1) serve as an internal marker and (2) assist in automatically identifying an external marker. With these two markers, lesion contour on the image can be accurately delineated using traditional watershed transformation. Density information will then be extracted from the segmented 2D lesion and help determine the 3D connected object that is a candidate of the lesion volume. The authors have developed a robust strategy to automatically determine internal and external markers for marker-controlled watershed segmentation. By manually placing a seed region-of-interest in the lesion to be delineated on a reference image, the method can automatically determine dual threshold values to approximately separate the lesion from its surrounding structures and refine the thresholds from the segmented lesion for the accurate segmentation of the lesion volume. This method was applied to 69 liver metastases (1.1-10.3 cm in diameter) from a total of 15 patients. An independent radiologist manually delineated all lesions and the resultant lesion volumes served as the "gold standard" for validation of the method's accuracy. The algorithm received a median overlap, overestimation ratio, and underestimation ratio of 82.3%, 6.0%, and 11.5%, respectively, and a median average boundary distance of 1.2 mm. Preliminary results have shown that volumes of liver metastases on contrast-enhanced CT images can be accurately estimated by a semiautomatic segmentation method.

    Full Text Available Abstract Purpose To study the efficacy of whole brain radiotherapy (WBRT with radiosensitizer in comparison with WBRT alone for patients with brain metastases in terms of overall survival, disease progression, response to treatment and adverse effects of treatment. Methods A meta-analysis of randomized controlled trials (RCT was performed in order to compare WBRT with radiosensitizer for brain metastases and WBRT alone. The MEDLINE, EMBASE, LILACS, and Cochrane Library databases, in addition to Trial registers, bibliographic databases, and recent issues of relevant journals were researched. Significant reports were reviewed by two reviewers independently. Results A total of 8 RCTs, yielding 2317 patients were analyzed. Pooled results from this 8 RCTs of WBRT with radiosensitizer have not shown a meaningful improvement on overall survival compared to WBRT alone OR = 1.03 (95% CI0.84–1.25, p = 0.77. Also, there was no difference in local brain tumor response OR = 0.8(95% CI 0.5 – 1.03 and brain tumor progression (OR = 1.11, 95% CI 0.9 – 1.3 when the two arms were compared. Conclusion Our data show that WBRT with the following radiosentizers (ionidamine, metronidazole, misonodazole, motexafin gadolinium, BUdr, efaproxiral, thalidomide, have not improved significatively the overall survival, local control and tumor response compared to WBRT alone for brain metastases. However, 2 of them, motexafin- gadolinium and efaproxiral have been shown in recent publications (lung and breast to have positive action in lung and breast carcinoma brain metastases in association with WBRT.

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

    Hidradenocarcinoma is a rare malignant tumour involving the sweat glands. It classically arises de novo, only rarely resulting from pre-existing hidradenoma. The literature contains few reports of lymph node metastasis in this tumour. We report a case of a patient with hidradenocarcinoma of the heel associated with inguinal node metastases. We report the case of a 64-year-old patient with a history of chronic smoking, who in the last two years developed a painless nodule in his right heel, with no prior injury, and which gradually increased in size to become an ulcerated tumour. Physical examination revealed a rounded tumour mass, ulcerated in the centre, and associated with multiple inguinal adenopathies. Histological and immunohistochemical examination was suggestive of hidradenocarcinoma. The patient had undergone extensive local excision with inguinal lymphadenectomy. Histological examination showed infiltration of lymph nodes by the tumour with capsular rupture. Radiotherapy was subsequently given. The outcome was good without recurrence after 34 months of follow-up. Hidradenocarcinoma is a rare malignant tumour. Diagnosis is based on histological and immunohistochemical examination. However, hidradenocarcinoma may on occasion be difficult to differentiate from hidradenoma, a benign tumour, hence the interest of complete surgical resection with safety margins even in the absence of cytological malignancy. Local recurrences are common. The occurrence of lymph node metastasis during hidradenocarcinoma has been described only rarely in the literature. Such metastases usually occur after tumour resection. The specific features of our case are the rarity of lymph node metastases in hidradenocarcinoma coupled with the fact that these metastases were discovered upon diagnosis of the primary tumour.

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

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002–2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2–8) days. Median survival was 26 months (95% confidence interval (CI), 19–33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2–23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    Purpose: Accurate segmentation and quantification of liver metastases on CT images are critical to surgery/radiation treatment planning and therapy response assessment. To date, there are no reliable methods to perform such segmentation automatically. In this work, the authors present a method for semiautomatic delineation of liver metastases on contrast-enhanced volumetric CT images. Methods: The first step is to manually place a seed region-of-interest (ROI) in the lesion on an image. This ROI will (1) serve as an internal marker and (2) assist in automatically identifying an external marker. With these two markers, lesion contour on the image can be accurately delineated using traditional watershed transformation. Density information will then be extracted from the segmented 2D lesion and help determine the 3D connected object that is a candidate of the lesion volume. The authors have developed a robust strategy to automatically determine internal and external markers for marker-controlled watershed segmentation. By manually placing a seed region-of-interest in the lesion to be delineated on a reference image, the method can automatically determine dual threshold values to approximately separate the lesion from its surrounding structures and refine the thresholds from the segmented lesion for the accurate segmentation of the lesion volume. This method was applied to 69 liver metastases (1.1–10.3 cm in diameter) from a total of 15 patients. An independent radiologist manually delineated all lesions and the resultant lesion volumes served as the “gold standard” for validation of the method’s accuracy. Results: The algorithm received a median overlap, overestimation ratio, and underestimation ratio of 82.3%, 6.0%, and 11.5%, respectively, and a median average boundary distance of 1.2 mm. Conclusions: Preliminary results have shown that volumes of liver metastases on contrast-enhanced CT images can be accurately estimated by a semiautomatic segmentation

    As the occurrence of malignant gliomas and brain metastases is increasing in elderly people, the authors report the definition of an optimal therapeutic strategy for these patients. For patients in good health condition, a prospective randomized showed a modest benefit of radiotherapy alone with respect to support cares in terms of survival. The radiotherapy scheme is discussed in terms of dose and number of fractions. It seems that the physiological age is a strong prognosis factor. Short communication

    Purpose: To describe the mammographical and ultrasound features of IM, and to compare radiological patterns of IM arising from different malignancies. Materials and methods: A retrospective search in the statistical database of our institution from January 2000 to December 2009 revealed 51 cases of intramammary metastases from solid malignancies. Additionally, a retrospective search in the Pubmed database was performed. Publications in the time interval from 1980 to 2010 were considered. After thorough analysis, 119 articles with 229 patients were involved in the study. Therefore, together with our cases our analysis comprises 280 patients. Mammographic and ultrasound findings of different IM were analyzed. Results: The detected metastases showed two main radiological patterns: intramammary masses (81.5%) and architectural distortion (18.5%). Carcinomas of the stomach caused more frequently an architectural distortion, whereas other malignancies tended to present as intramammary masses. The size of the masses ranged from 2 to 104 mm. The largest lesions occurred in rhabdomyosarcoma, followed by hepatocellular carcinoma and squamous cell carcinomas of the head and neck region. The smallest lesions arose from malignancies of the thyroid gland carcinoma. Most IM showed circumscribed margins, while breast lesions in rhabdomyosarcoma were rather microlobulated. On ultrasound, IM from lung cancer were usually inhomogenously hypoechoic with circumscribed margins and showed posterior shadowing in almost 50% of the cases. Breast metastases from ovarian carcinoma had typically microlobulated margins and posterior enhancement. Conclusion: IM can present with a broad spectrum of radiological features. Their imaging findings vary depending on the primary tumor.

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

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

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

    Despite decades of effort, little progress has been made to improve the treatment of cancer metastases. To leverage the central role of the mechanoenvironment in cancer metastasis, we present a mechanoresponsive cell system (MRCS) to selectively identify and treat cancer metastases by targeting the specific biophysical cues in the tumor niche in vivo. Our MRCS uses mechanosensitive promoter-driven mesenchymal stem cell (MSC)-based vectors, which selectively home to and target cancer metastases in response to specific mechanical cues to deliver therapeutics to effectively kill cancer cells, as demonstrated in a metastatic breast cancer mouse model. Our data suggest a strong correlation between collagen cross-linking and increased tissue stiffness at the metastatic sites, where our MRCS is specifically activated by the specific cancer-associated mechano-cues. MRCS has markedly reduced deleterious effects compared to MSCs constitutively expressing therapeutics. MRCS indicates that biophysical cues, specifically matrix stiffness, are appealing targets for cancer treatment due to their long persistence in the body (measured in years), making them refractory to the development of resistance to treatment. Our MRCS can serve as a platform for future diagnostics and therapies targeting aberrant tissue stiffness in conditions such as cancer and fibrotic diseases, and it should help to elucidate mechanobiology and reveal what cells "feel" in the microenvironment in vivo.

    Purpose: To evaluate a retrospective single-institution outcome after hypofractionated stereotactic body radiotherapy (SBRT) for adrenal metastases. Methods and Materials: Between February 2002 and December 2009, we treated 48 patients with SBRT for adrenal metastases. The median age of the patient population was 62.7 years (range, 43–77 years). In the majority of patients, the prescription dose was 36 Gy in 3 fractions (70% isodose, 17.14 Gy per fraction at the isocenter). Eight patients were treated with single-fraction stereotactic radiosurgery and forty patients with multi-fraction stereotactic radiotherapy. Results: Overall, the series of patients was followed up for a median of 16.2 months (range, 3–63 months). At the time of analysis, 20 patients were alive and 28 patients were dead. The 1- and 2-year actuarial overall survival rates were 39.7% and 14.5%, respectively. We recorded 48 distant failures and 2 local failures, with a median interval to local failure of 4.9 months. The actuarial 1-year disease control rate was 9%; the actuarial 1- and 2-year local control rate was 90%. Conclusion: Our retrospective study indicated that SBRT for the treatment of adrenal metastases represents a safe and effective option with a control rate of 90% at 2 years.

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

    To describe the clinical and MDCT findings of metastatic pancreatic tumors (MPTs) from various primary malignancies and to determine whether there are characteristic imaging features of MPTs according to the various histologies of primary tumors. Thirty-six patients with pathologically proven MPTs who underwent MDCT were retrospectively enrolled. Mean survival and factors associated with prolonged survival were analyzed using multivariate Cox regression analysis. MDCT was analyzed for the location, number, margin, and pattern and degree of enhancements of MPTs and main pancreatic duct (MPD) dilatations. Significant differences in CT features among the various histologies of MPTs were determined using the χ (2) or Fisher's exact test. The most common primary tumors metastasized to the pancreas were renal cell carcinomas (RCC) (n = 17), gastric cancers (n = 7), and colorectal cancers (n = 5). Mean survival was significantly different between RCC (106.7 months) and non-RCC (25.1 months) metastases (P MPTs are significantly different between the RCC and non-RCC metastases, potentially aiding in their differentiation and selection of the most appropriate management options for these patients.

  4. Thyroid Metastases from Renal Cell Carcinoma: Review of the Literature

    Full Text Available The thyroid gland is a rare site of clinically detectable tumor metastasis and kidneys are frequently the site of the parent malignancy. In the present review on thyroid metastases from renal cell carcinoma, cases were searched on PubMed by entering the strings: “renal carcinoma [or“hypernephroma”] AND thyroid metastasis/metastases”. Thus, we retrieved a total of 111 cases that were published between 1964 and 2007, a total that became 113 by adding two patients observed by us. The female to male ratio was 1.35:1. The primary renal cancer was almost always unilateral (90% (with no significant side preference and only rarely bilateral (9% in men, 4% in women, whereas bilaterality of thyroid metastases was relatively more frequent (28%. Thyroid metastasis from renal cancer was commonly single with a unique node that appears solid and hypoechoic at ultrasonography, approximately 9 years after nephrectomy. Concordance of lateralization was insignificantly greater for the right kidney/right thyroid lobe pattern (54% than for the left kidney/left thyroid lobe pattern (40%, regardless of gender. Finally, survival was longer for women. Thyroid metastases, even if rare in the clinical practice, must be considered in the differential diagnosis of a thyroid nodule, particularly in patients who have a history of malignancies.

    Metastases to the thyroid gland are uncommon, with rates reported between 0.02% and 1.4% of surgically resected thyroid specimens. Our goal was to present our experience with surgical management of metastases to the thyroid gland. Twenty-one patients with metastatic disease to the thyroid were identified from a database of 1,992 patients with thyroid cancer who had surgery during 1986-2005. Patient, tumor, treatment, and outcome details were recorded by analysis of charts. The median age at time of surgery was 68 (range, 39-83) years; 12 were men and 9 were women. All patients were managed by surgery, including lobectomy in ten patients, total thyroidectomy in six, completion thyroidectomy in two, and subtotal thyroidectomy in one. In two patients, the thyroid lesion was found to be unresectable at the time of surgery. Histopathology revealed renal cell carcinoma in ten, malignant melanoma in three, gastrointestinal adenocarcinoma in three, breast cancer in one, sarcoma in one, and adenocarcinoma from an unknown primary site in three patients. Seventeen patients have died. The cause of death in all 17 was widespread metastatic disease from their respective primary tumors. The median survival from surgery to death or last follow-up was 26.5 (range, 2-114) months. In patients with metastases to the thyroid gland, local control of metastatic disease in the central compartment of the neck can be successfully achieved with minimal morbidity with surgical resection in selected patients.

    Full Text Available Follicular thyroid adenoma and carcinoma are very common. Benign and malignant lesions are usually indistinguishable from cytology alone and often require confirmatory resection. The spread of follicular carcinoma is usually hematogenous and is treated with surgery and adjuvant radioactive iodine. Very rarely, metastases occur in the mediastinum. Patients usually present with severe compressive symptoms. With proper treatment and follow-up, the prognosis for these type of thyroid malignancies is excellent. In the case presented here, our patient presented to the Universiti Kebangsaan Malaysia Medical Center with a progressively enlarging anterior neck swelling. The swelling had started 10 years before his presentation. We diagnosed him with an advanced thyroid malignancy with bulky mediastinal metastases. After extensive investigations and counseling, we chose to treat the patient with tumor excision and mediastinal metastases resection. Typically, mediastinal resection involves the removal of the sternum and use of an acrylic implant to recreate the sternum. In this case, the sternum and ribs were removed with subsequent myocutaneous flap coverage for the wound defect. Our experience represents an alternative treatment option in cases where implant use is unsuitable.

    We describe video electroencephalography (video-EEG) correlates of transient neurological attacks due to plateau waves-paroxysmal elevations in intracranial pressure-in patients with leptomeningeal metastases. We identified 3 patients with leptomeningeal metastases, intracranial hypertension, and transient neurological attacks captured on video-EEG without evidence of seizures or epileptiform activity. We identified all clinical events on video and reviewed the corresponding EEG data for evidence of abnormalities. All 3 patients had mild to moderate slowing and 2 had frontal intermittent rhythmic delta activity during background EEG recording. There were 33 clinical events recorded and stereotyped for each patient. All 33 events were associated with an increase in delta range slowing of ≥30% compared to the background. This abnormality started ≤2 minutes before the onset of clinical symptoms and persisted for minutes after clinical resolution. This study is the first to carefully describe the electrographic correlates of transient neurological attacks due to plateau waves in patients with leptomeningeal metastasis. Clinical attacks were consistently associated with a possible EEG signature of diffuse delta range slowing. Future studies can validate the sensitivity and specificity of these EEG changes as a prognostic and/or response biomarker in patients with leptomeningeal metastases with or without intracranial hypertension.

    In 31 patients resected specimens from primary colorectal cancers, corresponding liver metastases and local recurrences were investigated for the staining pattern of lectins (PNL, UEA, WGA, HPA, SBA, RCA) and tissue antigens (CEA, SP, ACT) by immunohistochemistry. Comparison of staining patterns showed a loss of marker expression from normal colonic mucosa to colorectal primary carcinomas, and a tendency to marker loss from the primary tumour to liver metastases. However, even a neo-expression of markers not present in the primary tumour could be observed. For clinical use, serum markers observed in patient follow-up may be valuable even where the findings are negative at the time of primary tumour surgery. In contrast to the heterogenous marker map of primary tumours and metastases, comparison of primary and locally recurrent tumour revealed a staining pattern that was almost always identical. This supports the hypothesis that locoregional recurrences develop from remnant cells of the primary tumour left behind at surgery. There is no support for the thesis that locoregional recurrences arise from mucosal changes at the anastomosis or from suture material.

    Brain metastases are one of the factors complicating the treatment of a malignant tumor. Radiation therapy, especially radiosurgery, plays an important role in the modern treatment practice. During 2011-2016, 32 patients (from 29 to 67 years old) with multiple brain metastases underwent the treatment with SRS or SRT in our center. The number of secondary lesions varied from 2 to 11. Eight patients underwent microsurgery resection. Seven patients had recurrence after whole brain radiotherapy. Thirty patient underwent single fraction SRS and two patients with large metastases (bigger than 3 cm) underwent fractionated SRT. The treatment was done with dedicated linear accelerator stereotactic system Elekta Axesse (Elekta AB, Stockholm, Sweden). Different stereotactic fixation devices were used, namely, Leksell G frame, non-invasive HeadFIX frame, and reinforced thermoplastic mask (IMRT perforation). All treatments included a volumetric modulated arc therapy (VMAT) technique and of Inage Guided Radiation Therapy (IGRT) technique. All lesions were treated from a single isocenter, which allowed reducing the treatment time and overall dose to the patient's body. All patients suffered the treatment satisfactorily. No adverse reactions or complications were met in any case during or right after the treatment. Different stereotactic fixation devices and modern treatment techniques allowed creating an optimal, safe and comfortable way for patient treatment. The treatment time was from 15 to 50 minutes. Patient position verification after or during the treatment demonstrated good accuracy for all fixation types and low level of intrafraction motion.

    An outline of some general scintigraphic principles is followed by a non-isotopic study of liver metastases in order to compare the different methods. Liver scintigraphy is then examined from the viewpoint of both the method itself and the results to be expected. This study covered 62 observations of confirmed metastases and 36 for which a metastase was eliminated, i.e. 98 records altogether. The technique involved the use of technetium with a large (5-inch) scintillating crystal and a beehive collimator. No mishap occurred as a result of this examination. Scintigraphy offers a very useful means of exploration because false negatives are rare (4 doubtful cases for 58 positives in our series), but false positives are much more troublesome: 5 are noted in 36 cases and it seems that the real problem is confusion with cirrhosis. It is therefore necessary to follows up with arteriography, which seems to be a reliable examination in spite of the limited number of cases investigated [fr

    Infiltration of cancers by T cells is associated with improved patient survival and response to immune therapies; however, optimal approaches to induce T cell infiltration of tumors are not known. This study was designed to assess whether topical treatment of melanoma metastases with the TLR7 agonist imiquimod plus administration of a multipeptide cancer vaccine will improve immune cell infiltration of melanoma metastases. Eligible patients were immunized with a vaccine comprised of 12 melanoma peptides and a tetanus toxoid-derived helper peptide, and imiquimod was applied topically to metastatic tumors daily. Adverse events were recorded, and effects on the tumor microenvironment were evaluated from sequential tumor biopsies. T cell responses were assessed by IFNγ ELIspot assay and T cell tetramer staining. Patient tumors were evaluated for immune cell infiltration, cytokine and chemokine production, and gene expression. Four eligible patients were enrolled, and administration of imiquimod and vaccination were well tolerated. Circulating T cell responses to the vaccine was detected by ex vivo ELIspot assay in 3 of 4 patients. Treatment of metastases with imiquimod induced immune cell infiltration and favorable gene signatures in the patients with circulating T cell responses. This study supports further study of topical imiquimod combined with vaccines or other immune therapies for the treatment of melanoma.

    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.

    Breast invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) have different metastatic patterns, but the exact pattern of metastases from ILC is poorly known. This study aimed to determine the frequency of ILC metastases in atypical locations, with an emphasis on gastric metastases. Patients with ILC treated at the Saint-Sacrement Hospital (Quebec City, Canada) and the Maisonneuve-Rosemont Hospital (Montreal, Canada) between January 2003 and December 2009 were retrospectively reviewed. Demographic, clinical, and follow-up data were retrieved from the medical charts. Metastases that were diagnosed during follow-up were recorded. Among the 481 patients with ILC, 74 (15.4%) were diagnosed with metastases after a median follow-up of 46 months. Among these 74 patients, 41.9% had metastases in atypical sites. Five patients were diagnosed with histologically confirmed gastric metastases of ILC. Metastases of breast ILC to atypical sites might be more frequent than previously reported. Clinicians should keep a high level of suspicion when a patient with a history of ILC develops digestive symptoms. It is important to differentiate metastases from a primary GI tumor by using immunohistochemical markers. J. Surg.

    A total of 887 pedal lymphographies have been performed, 178 of them (173 men and 5 women) in a search for metastases of bladder cancer. Lymphography showed positive result for metastases in 110 patients (61,71 per cent); in 58 patients it was evaluated as negative for metastases (32,58 per cent) and in 9 (5,63 per cent) gave equivocal result. Most frequently affected were the iliac lywph groups, thf first barrier - 100 per cent involvement in proven metastases. Next in incidence of involvement (second barrier) were the paraortal lymphgroups - 55,45 per cent. Te external iliac inguinal groups were the ones most seldom affected

    Earlier studies proposed phosphatase and tensin homolog (PTEN) acts as a 3'-specific phosphatidylinositol phosphatase and inhibits the PI3K pathway. Recent reports show that PTEN mRNA expression is significantly downregulated in brain metastases compared to primary breast cancer. We focused on the differential expression of nuclear and cytoplasmic PTEN between primary tumors and brain metastases. We retrospectively studied 30 patients with histologically confirmed primary tumors and brain metastases. PTEN and PDK1 expression levels were examined by immunohistochemical staining and categorized as negative, positive, or strong positive expression. The difference in PTEN expression levels were compared, and the values with PPTEN was 100% at primary site, and 70% at brain metastases. Expression of nuclear PTEN was 87% at primary site, and 20% at brain metastases. Study results demonstrated that PTEN expression levels in brain metastases are lower compared with that of primary tumors. Especially, nuclear PTEN expression was significantly downregulated in various brain metastases. Higher PDK1 expression at brain metastases also confirmed the down regulation of PTEN function. Our findings indicate that decreased PTEN function by loss of nuclear PTEN expression may be associated with brain metastases. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Immune checkpoint inhibitors are reported to be effective in patients with brain metastases. However, detailed characteristics of the brain metastasis immune microenvironment remain unexplored. The median tumor-infiltrating lymphocyte (TIL) category in brain metastases was 5% (1-70%). In 46 pair-matched samples, the percentages of TILs were significantly higher in primary breast tumors than in brain metastases (paired t-test, P L1, PD-L2, and HLA class I was also performed. There are significantly fewer TILs in brain metastases than in primary breast tumors.

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

    In transit metastases (ITM) from extremity or trunk melanomas are subcutaneous or cutaneous lymphatic deposits of melanoma cells, distant from the primary site but not reaching the draining nodal basin. Superficial ITM metastases develop in 5-10% of melanoma patients and are thought to be caused by cells spreading along lymphatics; ITM appear biologically different from distant cutaneous metastases, these probably due to a haematogenous dissemination. The diagnosis is usually clinical and by patients, but patients need to be adequately educated in the recognition of this clinical situation. Ultrasound or more sophisticated instrumental devices may be required if the disease develops more deeply in the soft tissues. According to AJCC 2009 staging classification, ITM are included in stages IIIb and IIIc, which are considered local advanced disease with quite poor 5-year survival rates and outcomes of 24-54% at 5 years. 2 Loco-regional recurrence is in fact an important risk factor for distant metastatic disease, either synchronous or metachronous. Therapy for this pattern of recurrence is less standardised then in most other clinical situations and options vary based on the volume and site of the disease. Definitive surgical resection remains the preferred therapeutic approach. However, when surgery cannot be performed with a reasonable cosmetic and functional outcome, other options must be utilized. 3-6 Treatment options are classified as local, regional or systemic. The choice of therapy depends on the number of lesions, their anatomic location, whether or not these are dermal or subcutaneous, the size and the presence or absence of extra-regional disease.

    Distant metastases remain a significant problem in the treatment of malignancies. Surgical management of pulmonary metastases is considered valuable from the oncological view only on condition that R0 resection can be achieved. The whole spectrum of resection procedures can be used, however most commonly, extraanatomic lung resections are employed. It has not been fully evaluated whether the same efficacy can be obtained with thoracoscopic procedures. The aim was to compare the study complication rates with literature data. The secondary aim was to evaluate the benefit of intraoperative lung palpation examination. The authors present a retrospective study in a group of subjects operated for secondary pulmonary malignancies in the Motol Charles University 2nd Medical Faculty and Faculty Hospital Surgical Clinic, from 2003 to 2007. The authors compared the patient group's morbidity and 30-day mortality rates with literature data. Preoperative CT findings, intraoperative palpation findings and histological examination findings were assessed. Postoperative morbidity of the operated subjects was 16.5%, postoperative 30-day mortality was 0%. The authors compared the preoperative diagnostic data based on CT, the intraoperative findings and histological findings. During the total of 77 surgical procedures, including open and VATS procedures, the authors performed intraoperative palpation examination and detected 60 foci (24.6% out of the total removed foci) previously undetected on CT. All of the foci were of less than 5mm and in 55 cases, the foci were proved metastases. The outcome data showing low postoperative morbidity rates and nul 30-day mortality have confirmed that pulmonary metastasectomy is a safe method, a part of the complex oncological management. A surgeon's palpation finding is considered unsubstitutable in the detection of all lung foci and for necessary orientation in order to identify the safety margin in wedge resections. Therefore, the authors prefer

    The involvement of extra-ocular muscles in malignant diseases has been described only sporadically. The purpose of this study was to estimate the prevalence of orbital muscle lymphoma and metastases and to analyse their radiological findings. In the time period from January 2000 to January 2010, 11 patients with extra-ocular muscle malignancies (EOMM) were retrospectively identified in the radiological database of our institution. There were four women and seven men with a median age of 58 years (range, 47 to 72 years). In three patients non-Hodgkin lymphoma (NHL), in seven cases intramuscular metastases of solid tumours and in one patient plasmacytoma of orbital muscles were diagnosed. In all, magnetic resonance imaging (MRI) was performed on 11 patients using a 1.5-T MRI scanner (Magnetom Vision Sonata Upgrade, Siemens, Germany). The diagnosis of EOMM was confirmed histopathologically by muscle biopsy in all cases. The prevalence of orbital muscle involvement in plasmacytoma was 0.3%, in NHL 0.4% and in carcinomas 0.1%. Clinically, EOMM presented as painless proptosis and motility disturbance. Medial and lateral rectus muscles were involved in most patients. On T2-weighted images, the lesions were isointense or mixed iso-to-hyperintense in comparison to the unaffected musculature. On T1-weighted images, all tumours were homogeneously isointense. After intravenous administration of contrast medium, most lesions showed moderate heterogeneous enhancement. Lymphomas and metastases are rare lesions of the extra-ocular musculature with a prevalence below 0.5%. Their radiological and clinical signs are non-specific and include painless muscle enlargement or masses. They should be considered in the differential diagnosis of diseases of extra-ocular muscles.

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

Strontium-89 Chlorid kann darueber hinaus, wenn es adjuvant zur perkutanen Bestrahlung eingesetzt wird, das Auftreten von neuen Metastasen verzoegern und das interventionsfreie Intervall verlaengern. In der transkanadischen Multizenterstudie konnte ein Kosten sparender Effekt nachgewiesen werden. Die Nebenwirkungen der Behandlung muessen als gering eingestuft werden und beschraenken sich unter Verwendung von den beschriebenen Standarddosen auf eine Thrombo- und/oder Leukopenie maximal der Toxizitaet Grad II n.

    Background. Magnetic resonance imaging (MRI) is the recommended primary investigation method for metastatic spinal cord compression (MSCC). Initiating treatment before the development of motor deficits is essential to preserve neurological function. However, the relationship between MRI-assessed grades of spinal metastatic disease and neurological status has not been widely investigated. Purpose. To analyze the association between neurological function and MRI-based assessment of the extent of spinal metastases using two different grading systems. Material and Methods. A total of 284 patients admitted to our institution for initial radiotherapy or surgery for symptomatic spinal metastases were included in the study. Motor and sensory deficits were categorized according to the Frankel classification system. Pre-treatment MRI evaluations of the entire spine were scored for the extent of spinal metastases, presence and severity of spinal cord compression, and nerve root compression. Two MRI-based scales were used to evaluate the degree of cord compression and spinal canal narrowing and relate these findings to neurological function. Results. Of the patients included in the study, 28 were non-ambulatory, 49 were ambulatory with minor motor deficits, and 207 had normal motor function. Spinal cord compression was present in all patients with Frankel scores of B or C, 23 of 35 patients with a Frankel score of D (66%), and 48 of 152 patients with a Frankel score of E (32%). The percentage of patients with severe spinal canal narrowing increased with increasing Frankel grades. The grading according to the scales showed a significant association with the symptoms according to the Frankel scale (P < 0.001). Conclusion. In patients with neurological dysfunction, the presence and severity of impairment was associated with the epidural tumor burden. A significant number of patients had radiological spinal cord compression and normal motor function (occult MSCC)

    Purpose: In contrast with many analyses of surgical treatment for spinal metastases, there have been only a few recent well-documented publications assessing nonsurgical treatment. This paper is a study of the outcome of nonsurgical therapy for metastatic tumors of the spine. Methods and Materials: One hundred and one patients with spinal metastases were treated with radiation therapy and/or chemotherapy without surgical intervention between 1990 and 1995, in prospective analysis, and had follow-up for more than 24 months. This study included 59 men and 42 women with a mean age of 61 years (range: 14 to 81). Mean follow-up periods were 11 months for patients dying of the disease and 53 months for the survivors. Neurological status, pain relief, functional improvement, and cumulative survival rate were assessed. Results: Of the total treated, 67 patients (66%) were evaluated as being neurologically stable or improved after treatment. Pain relief was achieved in 67%, and 64% showed functional improvement. Primary lesion responsiveness to nonsurgical therapy influenced the survival, neurological recovery, pain control, and function. Neurological findings before therapy were useful in predicting ambulatory status after treatment. Conclusion: Nonsurgical treatment was often successful when primary tumors had responsiveness to radiation therapy and/or chemotherapy. We found this to be evident even when neurological deficits were found, particularly in lumbar spines. Spinal metastases of tumors with less responsiveness, unless patients were neurologically intact, responded poorly to therapy. Most of the patients who were successfully treated enjoyed relief lasting nearly until death. Their functional ability was limited by general debility, rather than by local tumor regeneration

    To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and

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

    Introduction: Ablation of colorectal liver metastases (CRLM) in highly selected patients is an option with curative potential. Patient selection and the ablative technique have continued to improve over the years. This study assessed the trends in long-term survival after ablation of CRLM. Methods...... divided into three subgroups according to time of ablation (2000-2004; 2005-2009, and 2010-2014). Survival was defined as the time from the first ablation procedure until death, censoring or end of the follow-up period (December 31, 2015). Results: 741 CRLM ablations were performed in 444 patients...

    Brain metastases management has evolved over the last fifteen years and may use varying strategies, including more or less aggressive treatments, sometimes combined, leading to an improvement in patient's survival and quality of life. The therapeutic decision is subject to a multidisciplinary analysis, taking into account established prognostic factors including patient's general condition, extracerebral disease status and clinical and radiological presentation of lesions. In this article, we propose a management strategy based on the state of current knowledge and available therapeutic resources. Copyright © 2015. Published by Elsevier SAS.

    The role of perioperative chemotherapy in the management of initially resectable colorectal liver metastases (CRLM) is still unclear. The EPOC trial [the European Organization for Research and Treatment of Cancer (EORTC) 40983] is an important study that declares perioperative chemotherapy as the standard of care for patients with resectable CRLM, and the strategy is widely accepted in western countries. Compared with surgery alone, perioperative FOLFOX therapy significantly increased progression-free survival (PFS) in eligible patients or those with resected CRLM. Overall survival (OS) data from the EPOC trial were recently published in The Lancet Oncology, 2013. Here, we discussed the findings and recommendations from the EORTC 40983 trial. PMID:25713806

    Regression of metastatic melanoma is a rare event, and review of the literature reveals a total of 76 reported cases since 1866. The proposed mechanisms include immunologic, endocrine, inflammatory and metastatic tumour nutritional factors. We conclude from this review that although the precise...... mechanisms remain unknown, some event must trigger the immune system to produce a stronger than normal response that results in regression of the melanoma metastases. Immunologic studies of patients with regression may disclose the underlying mechanisms and lead to new therapies of disseminated melanoma....

  11. Defining treatment for brain metastases patients: nihilism versus optimism.

    Treatment of brain metastases patients has included whole brain radiotherapy (WBRT) for over 50 years, and there is much data showing this to be associated with short-term gains. The integration of resection and radiosurgery to these patients allows some better prognostic groups to experience long-term local control and improvement in quality of life. The recursive partitioning analysis of the Radiation Therapy Oncology Group (RTOG) has been used as a predictive model for over a decade to identify three classes of patients. Number of lesions has been used to define treatment for a good prognostic subgroup that is eligible for surgery or radiosurgery, but there are few prospective studies of poorer prognosis brain metastases patients to evaluate the influence of number of lesions on the prediction of outcome. We examined patient, treatment and outcome parameters of all brain metastases patients in a 5-year period so that we could measure outcome and evaluate various factors on survival. This was a population-based study of all brain metastases patients in Southern Alberta between 2000 and 2005. It used an Excel spreadsheet database and STATA 8 software to analyze outcomes. The study included 568 patients representing 4.4% of our radiotherapy population. Median age, performance status and distribution of primary disease sites were comparable with other large series. Overall survival for the whole group was 3.05 months. Independent factors predicting for improved overall survival included younger age, KPS <70, less than four lesions and the use of stereotactic radiosurgery. Presence of extracranial disease or persistence of primary disease did not adversely impact survival outcome. This series shows that the number of lesions is a strong predictor of outcome. Integration of this factor into a decision-making model allows for identification of not only good prognosis patients who will benefit from aggressive treatment but it also facilitates decision making for poorer

    2010-01-01

    After having indicated the various origins of hepatic metastases, the authors outline that surgery and local treatment are applicable for 20 per cent of patients. But some of these local treatments may have contra-indications or may entail complications. Radiotherapy techniques used to have possible severe late effects on the liver, but new external radiotherapy apparatus, like the Cyberknife, can now be used. With its ballistic technique and its tracking system, it allows healthy tissues to be protected. It is also well tolerated by the patients. A comparative study with other local treatment techniques (radio-frequency, alcoolization, chemoembolisation) is still to be done. Short communication

    Full Text Available Primary cardiac sarcomas are extremely rare with only a few large case series and isolated case reports in the literature. In spite of their aggressive nature with high chances of local recurrence and distant metastases, these tumors and their treatment strategies remain incompletely defined. We report an unsuspected case of primary cardiac pleomorphic undifferentiated sarcoma in a 52-year-old female who presented with progressive dyspnea and palpitation. In the postoperative period, she was detected to have secondaries in brain and thyroid, confirmed thereafter, by fine-needle aspiration cytology.

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

    Full Text Available Cervical sarcomas are extremely rare tumors associated with a poor prognosis. We report the case of a 63-year-old woman who was admitted to our institution due to abnormal vaginal bleeding and abdominal pain. Physical examination revealed a large cervical mass that was biopsied. Pathological features were compatible with a leiomyosarcoma of the uterine cervix. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy. All histological and Immunohistochemical findings confirmed the diagnosis of leiomyosarcoma of the cervix. Adjuvant chemotherapy was started but unfortunately the disease progressed and 1 year after completion of the chemotherapy the patient developed lung metastases and eventually died.

    Full Text Available Intracranial occurrence of Ewing sarcoma (ES is unusual, with a skull-base location being anecdotal. We report a 29-year-old man who presented with rapidly progressive ophthalmoplegia, and was found to be harboring an infiltrative lesion involving the sphenoid sinus, sella, and clivus. He underwent trans-sphenoidal decompression of the lesion which was histologically suggestive of ES. He developed paraparesis 2 weeks after commencing adjuvant therapy. Imaging revealed two thoracic extradural lesions and florid vertebral and pulmonary metastases. This is the first report in indexed literature of a primary intracranial ES on the skull-base with disseminated extracranial disease.

  18. Genetic Characterization of Brain Metastases in the Era of Targeted Therapy

    2017-09-01

    Full Text Available In the current era of molecularly targeted therapies and precision medicine, choice of cancer treatment has been increasingly tailored according to the molecular or genomic characterization of the cancer the individual has. Previously, the clinical observation of inadequate control of brain metastases was widely attributed to a lack of central nervous system (CNS penetration of the anticancer drugs. However, more recent data have suggested that there are genetic explanations for such observations. Genomic analyses of brain metastases and matching primary tumor and other extracranial metastases have revealed that brain metastases can harbor potentially actionable driver mutations that are unique to them. Identification of genomic alterations specific to brain metastases and targeted therapies against these mutations represent an important research area to potentially improve survival outcomes for patients who develop brain metastases. Novel approaches in genomic testing such as that using cell-free circulating tumor DNA (ctDNA in the cerebrospinal fluid (CSF facilitate advancing our understanding of the genomics of brain metastases, which is critical for precision medicine. CSF-derived ctDNA sequencing may be particularly useful in patients who are unfit for surgical resection or have multiple brain metastases, which can harbor mutations that are distinct from their primary tumors. Compared to the traditional chemotherapeutics, novel targeted agents appear to be more effective in controlling the CNS disease with better safety profiles. Several brain metastases-dedicated trials of various targeted therapies are currently underway to address the role of these agents in the treatment of CNS disease. This review focuses on recent advances in genomic profiling of brain metastases and current knowledge of targeted therapies in the management of brain metastases from cancers of the breast, lung, colorectum, kidneys, and ovaries as well as melanoma.

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

    Full Text Available Abstract Background Resection of peritoneal metastases has been shown to improve survival in patients with abdominal metastatic disease from abdominal or extra abdominal malignancy. This study evaluates the benefit of peritoneal metastatic resection in patients with malignant small bowel obstruction and a past history of treated cancer. Patients and methods Patients undergoing laparotomy for resection of peritoneal metastases from recurrence of previous cancer between 1992–2003 were reviewed retrospectively. Data were collected about type of primary cancer, interval to recurrence, extent of the disease and completeness of resection, morbidity and mortality and long-term survival. Results Between 1992 and 2003 there were 79 patients (median age 62, range 19–91 who had laparotomy for small bowel obstruction due to recurrent cancer. The primary cancer was colorectal (31, gynaecologic cancer (19, melanoma (16 and others (13. Overall, the rate of complications was 35% and mortality was 10%. Median survival was 5 months; patients with history of colorectal cancer had better survival than other cancer (median survival 7 months vs. 4 months; p = 0.02. Multivariate analysis showed that the extent of recurrent disease was the only factor that affected overall survival. Conclusion Laparotomy for small bowel obstruction is a worthwhile option for patients with malignant small bowel obstruction. Although it is associated with significant morbidity and mortality it offers a reasonable survival benefit in particular for patients with completely resectable disease.

  5. Prevention of Bone Metastases in Breast Cancer Patients. Therapeutic Perspectives

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

    Colorectal cancer is one of the few malignant tumors in which synchronous or metachronous liver metastases [colorectal liver metastases (CRLMs)] may be treated with surgery. It has been demonstrated that resection of CRLMs improves the long-term prognosis. On the other hand, patients with un-resectable CRLMs may benefit from chemotherapy alone or in addition to liver-directed therapies. The choice of the most appropriate therapeutic management of CRLMs depends mostly on the diagnostic imaging. Nowadays, multiple non-invasive imaging modalities are available and those have a pivotal role in the workup of patients with CRLMs. Although extensive research has been performed with regards to the diagnostic performance of ultrasonography, computed tomography, positron emission tomography and magnetic resonance for the detection of CRLMs, the optimal imaging strategies for staging and follow up are still to be established. This largely due to the progressive technological and pharmacological advances which are constantly improving the accuracy of each imaging modality. This review describes the non-invasive imaging approaches of CRLMs reporting the technical features, the clinical indications, the advantages and the potential limitations of each modality, as well as including some information on the development of new imaging modalities, the role of new contrast media and the feasibility of using parametric image analysis as diagnostic marker of presence of CRLMs.

    Brain metastases (BM) occur in 20-40% of patients with cancer and 60-75% of patients with BM become symptomatic. Due to an aging population and advances in the treatment of primary cancers, patients are living longer and are more likely to experience complications from BM. The diagnosis of BM drastically worsens long-term survival rates, with multiple metastases being a poor prognostic factor. Until recently, the mainstay of treatment consisted of stereotactic radiosurgery (SRS), surgical resection, whole brain radiation therapy (WBRT), or a combination of these modalities. Systemic chemotherapy has been felt largely ineffective in the treatment of BM due to the presence of the blood-brain barrier (BBB), which includes efflux pumps on brain capillaries. Over the past decade however, researchers have identified therapeutic agents that are able to cross the BBB. These findings could make a multimodality treatment approach possible, consisting of surgery, radiation, immunotherapy, and targeted therapy, which could lead to better disease control in this patient population and prolong survival. In this review, we discuss present evidence on available targeted therapies and their role in the treatment of BM from primary tumors with the highest prevalence of central nervous system (CNS) involvement, specifically non-small cell lung cancer (NSCLC), breast cancer melanoma, and renal cell carcinoma.

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

    Carcinoid is a slowly-growing tumor from the group of neuroendocrine or APUD tumors. Characteristic of these tumors is the production of biogene amins & polypeptide hormones. 90% of all carcinoids are located in the GI system. A female patient, 68 years old, comes for a visit with signs of diffuse abdominal pain, diarrhea, irregular bowel movements, weakness, dyspnea and pretibial edemas. The gastroenterologist gives her only symptomatic therapy at first, and starts the examinations after her hospitalization (initial dg: Enterocolitis). One month later she visits again with the same complains. CT scan result shows steatosis hepatica and lots of liquids in the small bowel and colon. She underwent operation--resection of 20 cm of the small bowel with tumor masses and part-time ileostoma. The biopsy of the resected segment of the bowel shows multiple carcinoids. Our patient had no flushing of the skin and therefore couldn't be suspected clinically for this diagnosis. The intestinal carcinoid does not usually produce the carcionid syndrome unless hepatic metastases have occurred. The infiltration of the mesentery provokes an intense fibrotic reaction resulting in kinking of the bowel segments, which causes intestinal obstruction as it happened in this patient. As long as in our clinic we don't have this technique, it is much harder to make an early diagnosis. Fortunately our patient was diagnosed before liver metastases occurred, and therefore her treatment was successful.

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

    For a long time, treatment of peritoneal metastases (PM) was mostly palliative and thus, this status was link with “terminal status/despair”. The current multimodal treatment strategy, consisting of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), has been strenuously achieved over time, but seems to be the best treatment option for PM patients. As we reviewed the literature data, we could emphasize some milestones and also, controversies in the history of proposed multimodal treatment and thus, outline the philosophy of this approach, which seems to be an unusual one indeed. Initially marked by nihilism and fear, but benefiting from a remarkable joint effort of human and material resources (multi-center and -institutional research), over a period of 30 years, CRS and HIPEC found their place in the treatment of PM. The next 4 years were dedicated to the refinement of the multimodal treatment, by launching research pathways. In selected patients, with requires training, it demonstrated a significant survival results (similar to the Hepatic Metastases treatment), with acceptable risks and costs. The main debates regarding CRS and HIPEC treatment were based on the oncologists’ perspective and the small number of randomized clinical trials. It is important to statement the PM patient has the right to be informed of the existence of CRS and HIPEC, as a real treatment resource, the decision being made by multidisciplinary teams.

    1988-01-01

    63 patients, with brain metastases were treated with an accelerated split course regimen; irradiation was given to the whole brain in 3 daily fractions of 160 cGy each for 5 days a week. The cycle was repeated after 2 weeks to a total dose of 4800 cGy. Male-female ratio was 3:1. Median age was 58 years. The most frequent site of primary tumor was lung (41 patients), breast in 6 patients, melanoma in 3 patients, other sites in 8 patients and unknown cancer in 5 patients. Thirty-five patients had multiple brain metastases localizations. Two patients failed to complete the scheduled treatment: one because of early death and the other by refusal of therapy during treatment. Complete remission was obtained in 4 patients and partial remission in 24 patients. The median survival time was 21 weeks. The overall response rate was 42.5%. Toxicity was not considerable. The treatment results were not influenced by the site of primary tumor or by disease spreading; only the neurologic status before radiotherapy and the response to treatment influenced survival. The results obtained are similar to those reported by others; however, with the accelerated split course regimen the treatment time was reduced and a shorter period of hospitalization was required. 36 refs.; 2 figs.; 3 tabs

    Full Text Available Although brain metastases are one of the most frequently diagnosed sequelae of systemic malignancy, their optimal management still is not well defined. In that respect the different diagnostic and therapeutic approaches of BMs patients is an issue for serious discussions. Among the most commonly used diagnostic tools are computed tomography (CT scans, magnetic resonance imaging (MRI scans, single photon emission computed tomography (SPECT and positron emission tomography (PET scans etc. Nowadays the aforementioned diagnostic modalities are usually combined in order to obtain complete diagnostic information important for establishing the optimal treatment. With the present report we try to elaborate on the value of the modern diagnostic tools in differentiating between tumor progressions versus radiation necrosis in irradiated patients with resected brain metastases. Although the present advancement of the modern imaging modalities differentiating between tumor progression versus radiation necrosis is often difficult. Application of the metabolic imaging modalities like SPECT, PET and proton magnetic resonance spectroscopy (1H-MRS contributes for the diagnose but still pathological specimens remain a gold standard for distinguishing tumor from necrosis, because none of the imaging modalities is possible to reliably differentiate necrosis from progression in 100% of the cases.

    Dooms, G.C.; Mathurin, P.; Maldague, B.; Cornelis, G.; Malghem, J.; Demeure, R.

    1987-01-01

    A prospective study was performed to assess the value of MR imaging for demonstrating medullary compression due to vertebral metastases in cancer patients clinically suspected of presenting with that complication. Twenty-five consecutive unselected patients were studied, and the MR imaging findings were confirmed by myelography, CT, and/or surgical and autopsy findings for each patient. The MR examinations were performed with a superconducting magnet (Philips Gyroscan S15) operating at 0.5-T. MR imaging demonstrated the metastases (single or multiple) mainly on T1- weighted images (TR = 0.45 sec and TE = 20 msec). Soft-tissue tumoral mass and/or deformity of a vertebral body secondary to metastasis, compressing the spinal cord, was equally demonstrated on T1- and heavily T2-weighted images (TR = 1.65 sec and TE = 100 msec). In the sagittal plane, MR imaging demonstrated the exact level of the compression (one or multiple levels) and its full extent. In conclusion, MR is the first imaging modality for studying cancer patients with clinically suspected medullary compression and obviates the need for more invasive procedures

    Full Text Available Ovarian metastases from extragenital neoplasms are rare. The prevalent sites of the primary tumors were the breast, colorectum and the stomach. The Krukenberg tumor (KT is defined as a gastrointestinal cancer which metastasized to the ovaries. Metastasis to the ovary may appear at the time of diagnosis of the primary tumor (synchronous or during observation (metachronous. Common clinical presentations are abdominal distention, pain, palpable mass, bloating, ascites or pain during sexual intercourse. Diagnosis can be made by ultrasound examinations, CT or EMR scans, laparotomy and/or a biopsy of the ovary. The current standard treatment for patients with metastatic gastric cancer is systemic chemotherapy, however, treatment strategy for KTs from gastric cancer has not been clearly established and surgical treatment is considered mainly for metachronous tumors. The prognosis of patients with ovarian metastasis of gastric cancer origin is poorer compared with that of other primary tumors. Although the results of cytoreductive surgery – especially in combination with modern chemotherapy – seems to be promising, the optimal therapeutic strategies for such patients requires further prospective studies.

    We describe an unusual case of pleural drop metastases 21 years after complete resection of an encapsulated thymoma in a Southeast Asian patient with myasthenia gravis (MG). This investigation includes a case report and brief review of the literature. The patient presented in 2015 with generalized weakness, fatigue, and shortness of breath, but no diplopia, ptosis, dysphagia, or dysarthria. Because these symptoms were atypical for an MG exacerbation, a de-novo work-up was performed. Chest computed tomography (CT) showed numerous pleural nodules ("drop metastases"), and CT-guided biopsy revealed metastatic thymoma. The average disease-free interval for thymoma ranges from 68 to 86 months. Pleural and mediastinal recurrence are more common than distant hematogenous recurrence. Adverse prognostic factors include an initial higher Masaoka stage, incomplete resection, older age, and pleural or pericardial involvement. Despite apparent complete resection of thymoma, clinicians should remain vigilant for recurrence for as long as 20 years after initial management. Long-term follow-up with radiologic surveillance is recommended. Muscle Nerve 56: 171-175, 2017. © 2016 Wiley Periodicals, Inc.

  17. Melanoma brain metastases presenting as delirium: a case report

    Full Text Available Abstract Background Metastatic tumours sometimes present with neuropsychiatric symptoms, however psychiatric symptoms as rarely the first clinical manifestation. Cutaneous melanoma is the third most common cause of brain metastasis, with known risk factors increasing the chance of such central nervous system metastization. Objectives We present a clinical report of delirium as the first clinical manifestation of melanoma brain metastases, illustrating the relevance of an adequate and early differential diagnosis. Methods In addition to describing the clinical case, searches were undertaken in PubMed and other databases using keywords such as “brain metastasis”, “melanoma”, “agitation”, “psychiatric” and “delirium”. Results We here report the case of a 52-year-old female patient evaluated by Liaison Psychiatry after sudden onset of delirium while admitted at the Gastroenterology Department to study a hypothesis of pancreatitis. A head CT scan identified brain metastases, and after further examination, including brain biopsy, melanoma brain metastization was confirmed. Discussion Some of the diagnostic challenges of psychiatric symptoms associated with secondary brain tumours are discussed, underlining the importance of an adequate differential diagnosis when working in Psychiatry Liaison.

    We report the case of a 59-year-old female with progressive bilateral painful swelling of the thighs. MRI revealed multiple intramuscular necrotic masses with similar morphologic patterns. Whole-body CT and 18-FDG PET-CT scans demonstrated additional hypermetabolic muscular masses and a lobulated lesion within the left atrial cavity. As biopsy of a muscular mass was compatible with a poorly differentiated sarcoma with MDM2 oncogene amplification, two diagnoses were discussed: a dedifferentiated liposarcoma with muscle and heart metastases or a primary cardiac sarcoma, mainly a cardiac intimal sarcoma, with muscular metastases, which was finally confirmed by array-comparative genomic hybridization (aCGH) in a sarcoma reference center. This case emphasizes the potential for intimal sarcoma to disseminate in skeletal muscle prior to any other organ and the need for a genomic approach in addition to classical radiopathologic analyses to distinguish primary from secondary locations facing simultaneous tumors of the heart and skeletal muscles with MDM2 amplification.

    Despite the clinical significance of liver metastases, the difference between molecular and cellular changes in primary colorectal cancers (CRC) and matched liver metastases is poorly understood. In order to compare gene expression patterns and identify fusion genes in these two types of tumors, we performed high-throughput transcriptome sequencing of five sets of quadruple-matched tissues (primary CRC, liver metastases, normal colon, and liver). The gene expression patterns in normal colon and liver were successfully distinguished from those in CRCs; however, RNA sequencing revealed that the gene expression between primary CRCs and their matched liver metastases is highly similar. We identified 1895 genes that were differentially expressed in the primary carcinoma and liver metastases, than that in the normal colon tissues. A major proportion of the transcripts, identified by gene expression profiling as significantly enriched in the primary carcinoma and metastases, belonged to gene ontology categories involved in the cell cycle, mitosis, and cell division. Furthermore, we identified gene fusion events in primary carcinoma and metastases, and the fusion transcripts were experimentally confirmed. Among these, a chimeric transcript resulting from the fusion of RNF43 and SUPT4H1 was found to occur frequently in primary colorectal carcinoma. In addition, knockdown of the expression of this RNF43-SUPT4H1 chimeric transcript was found to have a growth-inhibitory effect in colorectal cancer cells. The present study reports a high concordance of gene expression in the primary carcinoma and liver metastases, and reveals potential new targets, such as fusion genes, against primary and metastatic colorectal carcinoma.

    While metastases directed therapy for oligometastatic disease is recommended in different cancer entities, the treatment of solitary metastases in head and neck squamous cell carcinoma (HNSCC) patients is not clearly defined. A retrospective analysis was performed on data from 143 HNSCC patients treated between 2001 and 2016 in a tertiary university hospital. Clinical factors and outcome were measured using the median survival of patients receiving metastases specific therapy in comparison with matched control patients. In 37 patients, distant metastases were treated specifically with either surgery and/or stereotactic ablative radiotherapy and had with 23.97 months a more than three times higher median survival than 10 untreated matched controls with potentially treatable distant metastases (7.07 months). Our retrospective analysis demonstrates a significant survival benefit for HNSCC patients who received a specific therapy regarding distant metastasis irrespective of localization as compared to a matched control cohort.

    Disseminated metastatic disease, including brain metastases, is commonly encountered in malignant melanoma. The classical treatment approach for melanoma brain metastases has been neurosurgical resection followed by whole brain radiotherapy. Traditionally, if lesions were either too numerous or surgical intervention would cause substantial neurologic deficits, patients were either treated with whole brain radiotherapy or referred to hospice and supportive care. Chemotherapy has not proven effective in treating brain metastases. Improvements in surgery, radiosurgery, and new drug discoveries have provided a wider range of treatment options. Additionally, recently discovered mutations in the melanoma genome have led to the development of "targeted therapy." These vastly improved options are resulting in novel treatment paradigms for approaching melanoma brain metastases in patients with and without systemic metastatic disease. It is therefore likely that improved survival can currently be achieved in at least a subset of melanoma patients with brain metastases.

    Full Text Available Abstract Background Consolidation with or without ground-glass opacity is the typical radiologic finding of lung metastases of adenocarcinoma from the gastrointestinal tract. Lung excavated metastases from gastrointestinal carcinoma are very rare. Case presentation The authors describe an unusual presentation of multiple cavitated lung metastases from colon adenocarcinoma and discuss the outcome of a patient. The absence both of symptoms and other disease localizations, the investigations related to different diagnostic hypotheses and the empirical treatments caused a delay in correct diagnosis. Only a transparietal biopsy revealed the neoplastic origin of nodules. Conclusions This report demonstrates that although lung excavated metastases are described in literature, initial failure to reach a diagnosis is common. We would like to alert clinicians and radiologists to the possibility of unusual atypical features of pulmonary metastases from colon adenocarcinoma.

    Molecular heterogeneity within primary breast carcinomas and among axillary lymph node (LN) metastases may impact diagnosis and confound treatment. In this study, we used short tandem repeated sequences to assess genomic heterogeneity and to determine hereditary relationships among primary tumor areas and regional metastases from 30 breast cancer patients. We found that primary carcinomas were genetically heterogeneous and sampling multiple areas was necessary to adequately assess genomic variability. LN metastases appeared to originate at different time periods during disease progression from different sites of the primary tumor and the extent of genomic divergence among regional metastases was associated with a less favorable patient outcome (P = 0.009). In conclusion, metastasis is a complex process influenced by primary tumor heterogeneity and variability in the timing of dissemination. Genomic variation in primary breast tumors and regional metastases may negatively impact clinical diagnostics and contribute to therapeutic resistance. PMID:26279627

    Ameloblastoma is a locally aggressive, epithelial odontogenic tumor involving mandibles and maxillas. Distant metastasis is a very rare condition and is designated as metastasizing (malignant) ameloblastoma despite its benign histological appearance. Up to now, only 27 well-documented cases of metastasizing ameloblastomas are reported in the literature, and lung is the most commonly involved organ. In previous reports of pulmonary metastasizing ameloblastomas, there was little description of the histopathologic finding. Here, the authors report 2 cases of pulmonary metastasizing ameloblastomas with special emphasis on their interesting, interstitial spread along alveolar septa, resulting in a unique 2-cell pattern under microscopic examination. Pulmonary metastasizing ameloblastoma may pose difficulty in diagnosis if the pathologist is not aware of patient's clinical history of ameloblastoma. © The Author(s) 2013.

    52 own cases are retrospectively evaluated in order to investigate the importance of radiotherapy for the treatment of the metastazing hypernephroma. The treatment is above all indicated in case of painful osseous metastases, but the success is retarded and often appears only after a focal dose of more than 30 Gy. Furthermore, radiotherapy of brain metastases and lymph node metastases within the mediastinum is often successful, whereas the irradiation of pulmonary metastases has to be judged less favorably. In most of all cases, surgical interventions are not an alternative, but a complementary treatment to radiotherapy. In default of promising systemic therapy methods, radiotherapy of metastases of the hypernephroma are a possibility to achieve a real palliative effect. (orig.) [de

    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 objectives of this study were to determine the cumulative incidence and timing of new brain metastases over the course of systemic therapy for metastatic melanoma and to identify prognostic factors for brain metastases. Chemo-naive patients underwent computed tomography or MRI of the brain every 6 weeks. The cumulative incidence of confirmed brain metastases was calculated at 12-week intervals. Univariable and multivariable competing risk regression models were used to assess the association between the development of brain metastases and potential risk factors of interest. Cumulative incidence with competing risk and competing risk regression was used to assess the brain metastasis-free interval from the time of diagnosis of stage IV disease. The clinical characteristics of the 315 patients with brain metastases were compared with those of 370 brain metastasis-free patients. Among patients with brain metastases, a significantly higher proportion had stage M1b and M1c disease at diagnosis compared with stage M1a and a greater proportion had metastatic disease in three or more visceral sites. Significantly shorter brain metastasis-free intervals were found in these patients compared with patients with M1a disease and those with no visceral metastases. More than 80% of the 230 patients who developed brain metastases during systemic therapy had their brain metastases confirmed within 60 weeks from the onset of advanced melanoma. Imaging studies at 12-week intervals for 60 weeks after the diagnosis of advanced melanoma will detect brain metastases in most of the patients who will eventually develop them.

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

  14. Is dual-phase abdominal CT necessary for the optimal detection of metastases from renal cell carcinoma?

    International Nuclear Information System (INIS)

    Jain, Y.; Liew, S.; Taylor, M.B.; Bonington, S.C.

    2011-01-01

    Aim: To determine whether dual-phase abdominal computed tomography (CT) detected more metastases than portal-phase CT alone in patients with renal cell carcinoma (RCC). Materials and methods: Audit committee approval was obtained. A retrospective audit was undertaken in 100 patients who underwent both arterial and portal phase CT. The CT images were independently reviewed by two consultant radiologists. The presence of metastases in the liver, pancreas, and contralateral kidney were recorded for each phase of contrast enhancement. Results: Metastases were identified in the liver in 27 patients, pancreas in 12, and contralateral kidney in 23 patients. Nine of the 27 (33%) liver metastases, three of the 12 (25%) pancreatic metastases, and two of the 23 (9%) renal metastases were only detected in the arterial phase, whilst four of the 27 (15%) liver metastases, three of the 12 (25%) pancreatic metastases, and two of the 23 (9%) renal metastases were only detected in the portal phase. Nine patients (9%) had metastases only visualized in the arterial phase, and six (6%) only in the portal phase. Detection of metastases only visible in the arterial phase led to a change of management in two patients (2%). Conclusion: The audit results support our current standard of dual-phase abdominal CT for optimal detection of RCC metastases.

    Full Text Available To identify pre-operative prognostic parameters for survival in patients with spinal epidural neoplastic metastasis when the primary tumour is unknown.This study was a retrospective chart review of patients who underwent surgery for spinal epidural neoplastic metastases between February 1997 and January 2011. The inclusion criteria were as follows: known post-operative survival period, a Karnofsky Performance Score equal to or greater than 30 points and a post-operative neoplastic metastasis histological type. The Kaplan-Meier method was used to estimate post-operative survival, and the Log-Rank test was used for statistical inference.A total of 52 patients who underwent 52 surgical procedures were identified. The mean age at the time of spinal surgery was 53.92 years (std. deviation, 19.09.

    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

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases.

    The liver is the second most common location of metastases following the lymph nodes. The accurate characterization of focal liver lesions in oncology patients is especially important because of the high prevalence of benign liver lesions and the possibility of co-existing benign and malignant lesions. The exact interpretation of these lesions is crucial for therapeutic decisions and thus for the prognosis of the patient. It is essential to detect all focal liver lesions and to distinguish benign from malignant lesions, especially in the management of oncology patients. Numerous imaging modalities are available for these challenges in the daily routine. An extensive understanding of the advantages and limitations of the various imaging modalities and knowledge of the morphology and the typical and atypical appearances of the different metastases is important. This review explains the radiological criteria for various metastases in different modalities. To evaluate the individual prognosis and risk assessment preoperatively, functional imaging is necessary. These personalized pretherapeutic diagnostics are discussed. (orig.) [German] Die Leber stellt nach den Lymphknoten die zweithaeufigste Lokalisation von Metastasen dar. Aufgrund der hohen Praevalenz gutartiger Leberlaesionen ist die genaue Charakterisierung fokaler Leberlaesionen bei Patienten mit bekanntem Malignom besonders wichtig, da maligne und benigne Tumoren koexistieren koennen. Die eindeutige Zuordnung dieser Laesionen ist entscheidend fuer die Therapie und somit die Prognose des Patienten. Insbesondere fuer das Management onkologischer Patienten ist es daher essenziell, alle fokalen Leberlaesionen zu detektieren und zwischen benignen und malignen zu differenzieren. Um dieser Anforderung im radiologischen Alltag nachzukommen, stehen derzeit zahlreiche Bildgebungsmodalitaeten zur Verfuegung. Daher sind sowohl ein tiefgreifendes Verstaendnis der Vorteile und Limitationen der verschiedenen diagnostischen

    From the clinical point of view, rectal cancer and colon cancer are clearly different nosological units in their progress and treatment. The aim of this study was to analyse and clarify the differences between the behaviour of liver metastases from colon and rectal cancer. The study of these factors is important for determining an accurate prognosis and indication of the most effective surgical therapy and oncologic treatment of colon and rectal cancer as a systemic disease. 223 patients with metastatic disease of colorectal carcinoma operated at the Department of Surgery, University Hospital in Pilsen between January 1, 2006 and January 31, 2012 were included in our study. The group of patients comprised 145 men (65%) and 117 women (35%). 275 operations were performed. Resection was done in 177 patients and radiofrequency ablation (RFA) in the total of 98 cases. Our sample was divided into 3 categories according to the location of the primary tumor to C (colon), comprising 58 patients, S (c. sigmoideum) in 61 patients, and R (rectum), comprising 101 patients. Significance analysis of the studied factors (age, gender, staging [TNM classification], grading, presence of mucinous carcinoma, type of operation) was performed using ANOVA test. Overall survival (OS), disease-free interval (DFI) or no evidence of disease (NED) were estimated using Kaplan-Meier curves, which were compared with the log-rank and Wilcoxon tests. As regards the comparison of primary origin of colorectal metastases in liver regardless of their treatment (resection and RFA), our study indicated that rectal liver metastases showed a significantly earlier recurrence than colon liver metastases (shorter NED/DFI). Among other factors, a locally advanced finding, further R2 resection of liver metastases and positivity of lymph node metastases were statistically significant for the prognosis of an early recurrence of the primary colon and sigmoid tumor. Furthermore, we proved that in patients with

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

    A 53-year-old man presented with a 12-year history of a progressively growing solid mass at his left shoulder. A 39 x 30 x 18-cm and 14.440-kg mass including the scapula was resected. Pathologic features were specific for chondroblastoma. During the 36-month follow-up, he had multiple inoperable metastatic lesions in his lungs. Histology of the transthoracic needle biopsy showed the metastatic nodules had features specific for chondroblastoma; however, the microscopic features additionally had hyperchromasia and increased mitotic activity in some areas. In the English literature, there are a few cases of chondroblastoma located in the scapula. It is exceptional to see this lesion in the sixth decade of life and with pulmonary metastases. (orig.)

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; alpha-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 reevaluated 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.

    This study was undertaken to determine whether 131-I labeled B72.3 monoclonal antibody, when injected subcutaneously in patients with known breast cancer, successfully detects lymph node metastases. Eleven women with biopsy-proven B72.3 antibody-reactive breast cancer (determined by immunoperoxidase staining) received subcutaneous injections of 500 μ Ci 131-I B72.3 in ipsilateral finger web spaces (or, in three cases, intralesional injections into the site of the breast tumor). The antibody is a IgGlk reactive with a high molecular weight antigen found on most breast carcinomas. Images of the axilla were obtained immediately after injection and serially to 72 hours. Nodal uptake was scored on a 0-3+ scale in a blinded fashion and correlated with pathologic findings from lymph node dissection

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.

    Clear-cell renal cell carcinoma (ccRCC) exhibits a broad range of metastatic phenotypes that have not been systematically studied to date. Here, we analyzed 575 primary and 335 metastatic biopsies across 100 patients with metastatic ccRCC, including two cases sampledat post-mortem. Metastatic competence was afforded by chromosome complexity, and we identify 9p loss as a highly selected event driving metastasis and ccRCC-related mortality (p = 0.0014). Distinct patterns of metastatic dissemination were observed, including rapid progression to multiple tissue sites seeded by primary tumors of monoclonal structure. By contrast, we observed attenuated progression in cases characterized by high primary tumor heterogeneity, with metastatic competence acquired gradually and initial progression to solitary metastasis. Finally, we observed early divergence of primitive ancestral clones and protracted latency of up to two decades as a feature of pancreatic metastases. Crown Copyright © 2018.

    From January 1966 through April 1980, 38 patients with squamous cell carcinoma and one patient with basal cell carcinoma of the skin with lymphatic metastases to the parotid area were treated with curative intent at the University of Florida. Fourteen were initially treated with surgery, nine inoperable patients were treated primarily with radiation therapy, and 16 were treated with planned combined therapy, i.e., superficial or total parotidectomies with preoperative or postoperative radiation therapy. The ultimate parotid area control rate for the group treated with radiation alone was 50%; there were no failures at doses above 6500 rad. The parotid area control rate was 88% in the combined-treatment group with no failures when the surgical margins of resection were free; however, when gross residual disease was left behind, only 4 to 6 lesions were controlled. The major sequela from combined therapy was sacrifice of the seventh nerve at surgery. Treatment methods are discussed

    Brain metastases (BMs) are the most common malignancy of the central nervous system. Recently it has been demonstrated that plasminogen activator inhibitor serpins promote brain metastatic colonization, suggesting that mutations in serpins or other members of the coagulation cascade can provide critical advantages during BM formation. We performed whole-exome sequencing on matched samples of breast cancer and BMs and found mutations in the coagulation pathway genes in 5 out of 10 BM samples. We then investigated the mutational status of 33 genes belonging to the coagulation cascade in a panel of 29 BMs and we identified 56 Single Nucleotide Variants (SNVs). The frequency of gene mutations of the pathway was significantly higher in BMs than in primary tumours, and SERPINI1 was the most frequently mutated gene in BMs. These findings provide direction in the development of new strategies for the treatment of BMs.

    Historically leptomeningeal metastases (LM) from melanoma have a poor prognosis, with a median survival of only 2 months despite treatment. Targeted therapy and immune checkpoint inhibitors are promising new treatment options in advanced melanoma. We sought to determine the impact of targeted therapy and immunotherapy on the outcome of melanoma patients with LM and to evaluate the influence of prognostic factors. We analyzed a series of 39 consecutive patients diagnosed with LM from melanoma between May 2010 and March 2015 treated at the Netherlands Cancer Institute. Thirty-four of these patients also had brain metastases (BM). Statistical analyses assessed the influence of clinical and biological characteristics on survival. Median overall survival of the entire cohort was 6.9 weeks (95% confidence interval 0.9-12.8). Due to a poor performance status or rapidly progressive disease, 14 patients received no treatment. Median overall survival of untreated patients after the diagnosis of LM was 2.9 versus 16.9 weeks for treated patients (P treatment was given, whereas 2 patients are in ongoing remission for 26 weeks (following dabrafenib) and 235 weeks (following WBRT and ipilimumab). Elevated serum lactate dehydrogenase and S100B at diagnosis of LM were associated with shorter survival. LM from melanoma still has an extremely poor prognosis. As observed in extracranial metastatic disease, new treatment modalities such as systemic targeted therapy and immune checkpoint inhibitors seem to increase overall survival in LM, and may result in long-term remission. These new treatment options should be considered in patients with LM. © The Author 2016. Published by Oxford University Press on behalf of the European Society for Medical Oncology.

    OBJECTIVE The aim of this systematic review was to provide an objective summary of the published literature pertaining to the use of stereotactic body radiation therapy (SBRT) specific to previously untreated spinal metastases. METHODS The authors performed a systematic review, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, of the literature found in a search of Medline, PubMed, Embase, and the Cochrane Library up to March 2015. The search strategy was limited to publications in the English language. RESULTS A total of 14 full-text articles were included in the analysis. All studies were retrospective except for 2 studies, which were prospective. A total of 1024 treated spinal lesions were analyzed. The median follow-up time ranged from 9 to 49 months. A range of dose-fractionation schemes was used, the most common of which were 16-24 Gy/1 fraction (fx), 24 Gy/2 fx, 24-27 Gy/3 fx, and 30-35 Gy/5 fx. In studies that reported crude results regarding in-field local tumor control, 346 (85%) of 407 lesions remained controlled. For studies that reported actuarial values, the weighted average revealed a 90% 1-year local control rate. Only 3 studies reported data on complete pain response, and the weighted average of these results yielded a complete pain response rate of 54%. The most common toxicity was new or progressing vertebral compression fracture, which was observed in 9.4% of cases; 2 cases (0.2%) of neurologic injury were reported. CONCLUSION There is a paucity of prospective data specific to SBRT in patients with spinal metastases not otherwise irradiated. This systematic review found that SBRT is associated with favorable rates of local control (approximately 90% at 1 year) and complete pain response (approximately 50%), and low rates of serious adverse events were found. Practice guidelines are summarized based on these data and International Stereotactic Radiosurgery Society consensus.

    2016-01-01

    Full Text Available Background: The most common sites of origin for neuroendocrine carcinoma are gastrointestinal tract and its accessory glands, and lungs. Materials and Methods: One-hundred fifty cases diagnosed with metastatic brain lesions were retrieved from hospital records within 5 years. For these cases, the primary neoplasm, histopathological classification, metastasis, treatment, and fate all were studied. Results: Intracranial deposits were detected in 10%. The primary lesion was in the lungs in 87% of patients, and 1 patient in the breast and 1 in esophagus. Pathological classification of the primary lesion was Grade 2 (MIB-1: 3–20% in 1 patient and neuroendocrine carcinoma (MIB-1: ≥21% in 14 patients. The median period from onset of the primary lesion up to diagnosis of brain metastasis was 12.8 months. About 33% of patients had a single metastasis whereas 67% patients had multiple metastases. Brain metastasis was extirpated in 33% of patients. Stereotactic radiotherapy alone was administered in 20% of patients, and brain metastasis was favorably controlled in most of the patients with coadministration of cranial irradiation as appropriate. The median survival period from diagnosis of brain metastasis was 8.1 months. Conclusion: Most of patients with brain metastasis from neuroendocrine carcinoma showed the primary lesion in the lungs, and they had multiple metastases to the liver, lymph nodes, bones, and so forth at the time of diagnosis of brain metastasis. The guidelines for accurate diagnosis and treatment of neuroendocrine carcinoma should be immediately established based on further analyses of those patients with brain metastasis.

    To describe the imaging and clinical characteristics of chordoma osseous metastases (COM). Our study was IRB approved and HIPAA compliant. A retrospective search of our pathology database for pathology-proven COM yielded 15 patients who had undergone MRI, CT, bone scan, and/or FDG-PET/CT. The imaging and clinical features of the COMs were recorded. A control group of age and gender matched chordoma patients without osseous metastasis was evaluated. The COM mean maximal dimension was 6.4 ± 4.0 cm. The majority (60%) of patients had one lesion. Extra-osseous soft tissue component was present in 85% and was larger than intra-osseous component in 76%. On MRI the lesions were heterogeneous but predominantly T2 hyperintense with hypointense septae, and with variable enhancement. On CT the lesions were typically destructive or permeative; calcifications were rare. The extent of the soft tissue component was isodense to muscle on CT and therefore better evaluated on MRI. COM was in a body part contiguous to the site of the primary tumor. Compared to the controls, COM patients were more likely to have local recurrence (P = 0.0009) and positive resection margins (P = 0.002). At 1 year, 33% of COM patients were deceased and 13% had progressive metastases. COM are associated with large extra-osseous soft tissue components, which are better visualized by MRI. They are often located in a body part contiguous to the site of the primary tumor, portend poor prognosis, and are associated with positive resection margins and local recurrence. (orig.)

    2016-01-01

    The presence of multiple symptomatic pulmonary nodules and one cardiac tumour in a child requires urgent diagnosis and treatment. Until a few decades ago, the diagnosis of a cardiac tumour was difficult and was based on a high index of suspicion from indirect signs, and required angiocardiography for confirmation. Echocardiography and other imaging techniques have also helped in the detection of cardiac neoplasms. However, it is not always easy to make the correct diagnosis. The case is presented of a 12 year-old boy with pulmonary symptoms, and diagnosed with a cardiac tumour with lung metastases. The presence of numerous pulmonary nodules was confirmed in our hospital. The echocardiogram detected a solid cardiac nodule in the right ventricle. Magnetic resonance imaging confirmed the findings and the diagnosis. Puncture-aspiration of a lung nodule gave the diagnosis of hydatidosis. He underwent open-heart surgery with cardiac cyst resection and treated with anthelmintics. The lung cysts were then excised, and he recovered uneventfully. This child had multiple pulmonary nodules and a solid cardiac nodule, and was suspected of having a cardiac tumour with pulmonary metastases. However, given the clinical history, background and morphology of pulmonary nodules, another possible aetiology for consideration is echinococcosis. The clinical picture of cardiac hydatidosis and its complications is highly variable. The clinical history is essential in these cases, as well as having a high index of suspicion. Hydatidosis should be included in the differential diagnosis of a solid, echogenic, cardiac nodule. The treatment for cardiopulmonary hydatid cysts is surgical, followed by anthelmintics.

    ObjectiveTo evaluate prognostic factors associated with local control and disease-free-survival (DFS) of oligometastatic breast cancer patients treated by percutaneous thermal ablation (PTA).Materials and MethodsSeventy-nine consecutive patients (54.5 ± 11.2 years old) with 114 breast cancer metastases (28.9 ± 16.1 mm in diameter), involving the lungs, the liver, and/or the bone, were treated using PTA with a curative intent. The goal was to achieve a complete remission in association with systemic chemotherapy and hormonal therapy. We retrospectively evaluated the prognostic factors associated with 1- and 2-year local control and the 1- and 2-year DFS rates.ResultsThe 1- and 2-year local control rates were 83.0 and 76.1 %, respectively. Tumor burden was associated with a poorer outcome for local control after PTA (HR 1.027 by additional millimeter, p = 0.026; >4 cm HR 3.90). The 1- and 2-year DFS rates were 54.2 and 30.4 %, respectively. In multivariate analysis, triple-negative histological subtype and increased size of treated metastases were associated with a poorer DFS (HR 2.22; 95 % CI [1.13–4.36]; p = 0.02 and HR 2.43; 95 % CI [1.22–4.82]; p = 0.011, respectively).ConclusionPTA is effective for local control of breast cancer oligometastases. Tumor burden >4 cm and triple-negative histological subtype are associated with a poorer outcome.

    Brain metastases are unusual from urethelial carcinoma of bladder and particularly the occurrence of leptomeningeal metastases is extremely rare, with few cases described in the literature. We present a case of a 45-year-old man with a rare brain metastases as the first metastatic manifestation secondary to urethelial carcinoma of bladder followed by leptomeningeal metastases without any other organ involvement. Eleven months after the diagnosis of high-grade urethelial carcinoma of bladder (T2N0M0), the patient was detected having brain metastases by MRI. FDG PET/CT images for the metastatic evaluation showed no abnormal FDG uptake elsewhere in the body except the brain. Histopathology examination from brain lesion demonstrated the cerebral lesion to be a metastatic urothelial carcinoma. Two months later, the patient was diagnosed to have leptomeningeal metastases by MRI. Our patient's condition gradually worsened, and he died 3 months after the diagnosis of leptomeningeal metastases. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

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

    Purpose: Differentiating glioblastoma from brain metastases is important for therapy planning. Diffusion tensor imaging (DTI) was described as a promising tool, however with conflicting results. Aim: of this study was to analyze the clinical utility of DTI for the differentiation of brain metastases and glioblastoma. Methods: 294 patients (165 glioblastoma, 129 brain metastases) with preoperative DTI were included in this retrospective study. Fractional anisotropy (FA) was measured via regions of interest (ROIs) in the contrast-enhancing tumor, the necrosis and the FLAIR-hyperintense non-enhancing peritumoral region (NEPTR). Two neuroradiologists classified patient cases as glioblastoma or brain metastases without and with knowledge of FA values. Results: Glioblastoma showed significantly higher FA{sub contrast} (median glioblastoma = 0.33, metastases = 0.23; P < 0.001) whereas no significant difference was observed for FA{sub NEPTR} (0.21 vs. 0.22; P = 0.28) and for FA{sub necrosis} (0.17 vs. 0.18, P = 0.37). FA improved diagnostic accuracy of the neuroradiologists significantly from an AUC of 0.84/0.85 (Reader1/Reader2) to 0.89/0.92. Conclusions: Glioblastoma show significantly higher FA values in the contrast enhancing tumor part than brain metastases. Implementation of a ROI-based measurement of FA values and FA color maps in clinical routine helps to differentiate between glioblastoma and brain metastases.

    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.

    To assess the appearance of gastrointestinal melanoma metastases on CT and PET/CT and evaluate the diagnostic value of CT and PET/CT compared with surgery and histopathology. We retrospectively included 41 consecutive patients (aged 56.1 ± 13.5 years) with gastrointestinal melanoma metastases who underwent preoperative imaging (CT: all, PET/CT: n = 24) and metastasectomy. Two blinded radiologists assessed CT and PET/CT for gastrointestinal metastases and complications. Diagnostic accuracy and differences regarding lesion detectability and complications were assessed, using surgical findings and histopathology as standard of reference. Fifty-three gastrointestinal melanoma metastases (5.0 ± 3.8 cm) were confirmed by surgery and histopathology. Lesions were located in the small bowel (81.1 %), colon (15.1 %) and stomach (3.8 %), and described as infiltrating (30.2 %), polypoid (28.3 %), cavitary (24.5 %) and exoenteric (17.0 %). Fifteen patients (37 %) had gastrointestinal complications. Higher complication rates were associated with large and polypoid lesions (p ≤.012). Diagnostic accuracy was high for CT and PET/CT (AUC ≥.802). For reader B (less experienced), CT yielded lower diagnostic accuracy than PET/CT (p =.044). Most gastrointestinal melanoma metastases were located in the small bowel. Large and polypoid metastases were associated with higher complication rates. PET/CT was superior for detection of gastrointestinal melanoma metastases and should be considered in patients with limited disease undergoing surgery. (orig.)

    To compare the findings of high-resolution computed tomography (HRCT) between patients with miliary metastases and miliary tuberculosis. Between May 1998 and April 2002, 11 patients with miliary metastases and 18 with miliary tuberculosis underwent HRCT, and we reviewed the findings. In miliary metastases, the primary lesions were adenocarcinoma of the lung (n=2), stomach (n=1), or pancreas (n=1), or unknown origin (n=5), and papillary carcinoma of the thyroid (n=2). Two radiologists blinded to the clinical and pathologic data reached a consensus regarding nodule size and margin, their distribution and coalescence, interstitial involvement, and other ancillary HRCT findings. Data were analyzed using the chi-square test. CT scans showed numerous 1 to 5-mm nodules randomly distributed throughout both lungs of all patients. Nodules larger than 1.5 mm in diameter were more often seen in miliary metastases (81.9%). In six (54.5%) patients with miliary metastases and in three (16.7%) with miliary tuberculosis, nodule size varied (p<0.05). Pleural effusion occurred in three (27.3%) patients with miliary metastases and three (16.7%) with miliary tuberculosis. Interlobular septal thickening (100%) and peribronchovascular thickening (63.6%) were more common in miliary metastases than in miliary tuberculosis (p<0.01). Lymph node enlargement was seen in 11 (100%) patients with miliary metastases and five (27.8%) with miliary tuberculosis (P<0.001). At HRCT, lymph node enlargement and both interlobular and peribronchovascular thickening are more commonly observed in miliary metastases than in miliary tuberculosis.

    Background  Our pilot study describes our initial experience to do a laser resection of lung metastases under video-assisted thoracoscopic control via a minithoracotomy. With this approach, if needed, mediastinal lymphadenectomy is also possible. Methods  In this study, 15 patients (11 men and 4 women, mean age: 60 years) with resectable lung metastases of different solid primary tumors (colorectal cancer in seven patients, melanoma in three patients, renal cell carcinoma in two patients, and one each with oropharyngeal cancer, breast cancer, and seminoma) were included. An anterior minithoracotomy incision (approximately 5-7 cm length) was created in the fifth intercostal space and a soft tissue retractor (Alexis Protector; Applied Medical) was positioned. Two additional working ports were inserted. The entire lung was palpated via the minithoracotomy. All detected lung metastases were removed under thoracoscopic control. Nonanatomic resections were performed using a diode-pumped neodymium-doped yttrium aluminium garnet laser (LIMAX120; KLS Martin GmbH & Co KG) with a laser power of 80 W in a noncontact modus. Deeper parenchymal lesions were sutured. Results  A total of 29 lung metastases up to 30 mm in size were resected and all metastases diagnosed on preoperative imaging were detected. All diagnosed lung metastases were completely resected (R0). The median operation time was 102 (range: 85-120) minutes. Median blood loss was 47.6 mL and no postoperative complications occurred. Neither local recurrences nor new lung metastases were observed within 6 months after the procedures. Conclusion  Video-assisted laser resection of lung metastases is safe, effective, and fulfills the requirements of modern lung metastases surgery. Georg Thieme Verlag KG Stuttgart · New York.

    Metastasizing adnexal carcinomas are rare; thus, currently there is no uniform treatment guideline. Chemotherapeutic drugs that selectively target cancer-promoting pathways may complement conventional therapeutic approaches. We performed immunohistochemistry (epidermal growth factor receptor (EGFR), HER2, and CD117), EGFR and ERBB2 fluorescence in situ hybridization (FISH), and multiplexed SNaPshot® genotyping (testing for recurrent mutations in 15 cancer genes including BRAF, EGFR, KRAS, PIK3CA, and TP53) on primary tumors and corresponding metastases of 14 metastasizing adnexal carcinomas (three apocrine, six eccrine, two hidradenocarcinomas, two porocarcinomas, and one aggressive digital papillary adenocarcinoma). Metastasis to regional lymph node was most common, followed by skin and then lungs. Follow-up was available in 12 patients (5 months to 8 years) with 1 died of widespread metastases. Although EGFR overexpression was a prevalent feature in this cohort, seen in 7/11 (64%) primary tumors and 10/14 (71%) metastases; FISH for EGFR gene amplification was negative in 9 tested primary tumors and 12 metastases. FISH of the one primary tumor and three metastases with 2+ HER2 overexpression revealed a low level of ERBB2 gene amplification in one apocrine carcinoma and corresponding metastasis. CD117 expression was seen only in rare cases. PIK3CA (2/12, 17%) and TP53 (3/12, 25%) mutations were detected in two (one hidradenocarcinoma, one porocarcinoma) and three (one eccrine, one hidradenocarcinoma, and one aggressive digital papillary adenocarcinoma) cases, respectively. The role of EGFR inhibitor therapy in metastasizing adnexal carcinomas with protein overexpression remains unclear. Targeted therapy including PI3K pathway inhibitors might be a potential treatment for rare cases of adnexal carcinomas with metastases.

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

    Conclusions: Cases of metastases to the penis are very rare and often carry a grave prognosis, as it is a late manifestation of malignant disease. The average survival from the diagnosis of penile metastases in our review was just under 4 months. It is however important to be aware and recognise this rare phenomenon, and differentiate it from primary penis cancer. Treatment of penile metastases is mostly palliative, but much can be done to improve the patient's quality of life. Early correct diagnosis may also alter the treatment of the primary tumour.

    Full Text Available The progression of organ-confined prostate cancer to metastatic cancer is inevitably fatal. Consequently, identification of structural changes in the genome and associated transcriptional responses that drive this progression is critical to understanding the disease process and the development of biomarkers and therapeutic targets. In this study, whole genome copy number changes in genomes of hormone-naïve lymph node metastases were profiled using array comparative genomic hybridization, and matched primaries were included for a subset. Matched primaries and lymph node metastases showed very similar copy number profiles that are distinct from primary tumors that fail to metastasize.

    Due to increased effectiveness of cancer treatments and increasing survival rates, metastatic disease has become more frequent compared to the past, with the spine being the most common site of bony metastases. Diagnostic imaging is an integral part of screening, diagnosis and follow-up of spinal metastases. In this article, we review the principles of multimodality imaging for tumor detection with respect to their value for diagnosis and stereotactic body radiation therapy planning for spinal metastases. We will also review the current international consensus agreement for stereotactic body radiation therapy planning, and the role of imaging in achieving the best possible treatment plan.

    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....... The reason for the large difference in OS despite similar DFS/PFS is likely different metastatic patterns at relapse/progression. Relapse in the liver transplantation group was often detected as small, slowly growing lung metastases, whereas progression of nonresectable liver metastases was observed...

    We report the case of a patient in whom brain MR imaging was requested for initial symptoms of intracranial hypertension. The presence of multiple intracranial hemorrhagic lesions suggested brain metastases. Body screening showed periosteal osteosarcoma of the left fibula with no lung metastases, but with a patent foramen ovale which probably allowed neoplastic cells to reach the brain without being filtered through the lungs. The conclusion of this study was that a left-right cardiac communication is to be considered in cases of isolated brain metastases from osteosarcoma. (orig.). With 3 figs

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

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

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available Cannonball metastases refer to well-defined spherical nodules scattered over both lungs, being a classical presentation of hematogenous tumor spreading. Striking progression of lung metastases without established primary malignancy can raise a diagnostic challenge. We herein report three cases with cannonball metastases at initial presentation. Two patients ended up having a choriocarcinoma but no awareness of the presence of primary tumors, and the third had abrupt lung metastases of endometrial cancer while she was being asymptomatic. Relentless progression was illustrated by clinical and radiographic changes. Ectopic expression of human chorionic gonadotropin (hCG would seemingly go some way responsible for fulminant cancer spreading associated with poor prognosis in our patients. The goal of this presentation is to raise awareness of ectopic hCG expression in patients presenting with similar astonishing scenarios.

    International Nuclear Information System (INIS)

    Matsumoto, T.; Ando, K.; Koike, S.

    1988-01-01

    We have previously reported that abdominal irradiation prior to i.v. injection of syngeneic tumor cells reduced metastases in lung. Our report described an investigation of the significance of intestinal organisms in the radiation effect. We found that eliminating intestinal organisms with antibiotics totally abolished the radiation effect. Monoassociation of germ-free mice revealed that the radiation effect was observable only for Enterobacter cloacae, never for Streptococcus faecium, Bifidobacterium adlesentis, or Escherichia coli. After abdominal irradiation of regular mice, E. cloacae multiplied in cecal contents, adhered to mucous membranes, invaded the cecal wall, and translocated to mesenteric lymph nodes. Intravenous administration of E. cloacae in place of abdominal irradiation inhibited metastases. E. cloacae-monoassociated mice developed fewer metastases than germ-free mice, and the reduction was further enhanced by abdominal irradiation. We concluded that abdominal irradiation caused the invasion of E. cloacae from the mucous membrane of the intestine and inhibited formation of lung metastases

    Haumann, S.

    1986-01-01

    The thesis is aimed at reviewing a therapy plan worked out previously for the treatment of patients with cerebral metastases, and at studying computerized tomography for its potential benefit in the planning and implementation of radiotherapy. 61 patients were irradiated and examined neurologically and by CT before, during and after treatment, thus allowing a thorough-going analysis of the findings. CT evaluations differentiated between the change of volume and the number of metastases as well as the change of the extension of perifocal oedema. Our experience shows a dose of 30 Gy related to the centre of the skull to be sufficient, on the one hand, in order to determine by CT whether or not the existing intracerebral tumour metastases of the patient concerned will be accessible by radiotherapy at all, and, on the other hand, to destroy metastases smaller than 5 mm which cannot be detected by CT.

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

    Full Text Available This paper analyzes the experience in treating 20 patients with nonseminomatous germ cell tumors metastasizing to the brain. It presents brain metastasis-associated factors: multiple lung metastases; IGCCCG poor prognosis; and a baseline human chorionic gonadotropin level of > 50000 mIU/ml. The authors have identified a group to be screened for brain metastasis, which includes patients with intermediate/poor prognosis and multiple lung metastases. Long-term survival was achieved in 45 % of patients with baseline brain damage and in 22 % of those with metastases revealed after first-line chemotherapy. The positive prognostic factors associated with long-term survival were a single brain lesion, no neurological symptoms, and achievement of clinical complete personse in the brain.

    The aim of this study was to report a case of metastatic uveal melanoma in which radioembolized nodular liver metastases decreased in size while infiltrative sinusoidal metastases progressed, leading to jaundice without obstruction of the biliary ducts. The relevant clinical features, imaging, and histopathologic findings of this case are reviewed. A 61-year-old Caucasian male with a history of uveal melanoma of the left eye status post plaque brachytherapy developed numerous liver metastases. After progression on systemic therapies, he underwent palliative radioembolization. Despite some radiographic improvement in the liver metastases, he developed hyperbilirubinemia without biliary tract obstruction or signs of liver failure. A biopsy of radiographically normal liver demonstrated extensive sinusoidal infiltration with melanoma. Distinct angiographic and histopathologic growth patterns of metastatic uveal melanoma differ in their amenability to radioembolization. Sinusoidal infiltration may lead to hyperbilirubinemia in the absence of overt obstruction or liver failure.

    The multimodality management of brain metastases has undergone significant refinement in the last decade. Although brain metastases remain a significant source of morbidity and mortality for many cancer patients, aggresive management has led to pronounced gains in neurological functioning, disease free survival and overall survival compared to standard treatment regimens consisting of only whole brain radiation therapy. Representative studies reviewing the role of aggressive management approaches including surgical resection with or without whole brain radiation therapy or non-surgical approaches employing stereotactic radiosurgery alone or in combination with whole brain radiation therapy are highlighted. Additionally, the emerging role of systemic agents showing distinct clinical activity in patients with brain metastases are also discussed. As we continue to gain advances in systemic therapies for metastatic disease, local control of brain metastases in these patients is likely to become more critical in improving survival and quality of life, thereby calling for a more aggressive multi-modal approach to this population of patients.

    We have previously reported that abdominal irradiation prior to i.v. injection of syngeneic tumor cells reduced metastases in lung. Our report described an investigation of the significance of intestinal organisms in the radiation effect. We found that eliminating intestinal organisms with antibiotics totally abolished the radiation effect. Monoassociation of germ-free mice revealed that the radiation effect was observable only for Enterobacter cloacae, never for Streptococcus faecium, Bifidobacterium adlesentis, or Escherichia coli. After abdominal irradiation of regular mice, E. cloacae multiplied in cecal contents, adhered to mucous membranes, invaded the cecal wall, and translocated to mesenteric lymph nodes. Intravenous administration of E. cloacae in place of abdominal irradiation inhibited metastases. E. cloacae-monoassociated mice developed fewer metastases than germ-free mice, and the reduction was further enhanced by abdominal irradiation. We concluded that abdominal irradiation caused the invasion of E. cloacae from the mucous membrane of the intestine and inhibited formation of lung metastases.

    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.

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

    To assess the appearance of gastrointestinal melanoma metastases on CT and PET/CT and evaluate the diagnostic value of CT and PET/CT compared with surgery and histopathology. We retrospectively included 41 consecutive patients (aged 56.1 ± 13.5 years) with gastrointestinal melanoma metastases who underwent preoperative imaging (CT: all, PET/CT: n = 24) and metastasectomy. Two blinded radiologists assessed CT and PET/CT for gastrointestinal metastases and complications. Diagnostic accuracy and differences regarding lesion detectability and complications were assessed, using surgical findings and histopathology as standard of reference. Fifty-three gastrointestinal melanoma metastases (5.0 ± 3.8 cm) were confirmed by surgery and histopathology. Lesions were located in the small bowel (81.1 %), colon (15.1 %) and stomach (3.8 %), and described as infiltrating (30.2 %), polypoid (28.3 %), cavitary (24.5 %) and exoenteric (17.0 %). Fifteen patients (37 %) had gastrointestinal complications. Higher complication rates were associated with large and polypoid lesions (p ≤ .012). Diagnostic accuracy was high for CT and PET/CT (AUC ≥ .802). For reader B (less experienced), CT yielded lower diagnostic accuracy than PET/CT (p = .044). Most gastrointestinal melanoma metastases were located in the small bowel. Large and polypoid metastases were associated with higher complication rates. PET/CT was superior for detection of gastrointestinal melanoma metastases and should be considered in patients with limited disease undergoing surgery. • Gastrointestinal melanoma metastases (GI-MM) are rare but often cause serious gastrointestinal complications. • Early detection of GI-MM is important to prevent complications and guide surgery. • PET/CT is superior to CT for detection of GI-MMs. • PET/CT should be considered for patients with limited disease before surgical resection.

    Purpose: To evaluate feasibility and patterns of failure in adult patients with Ewing sarcoma (ES) treated with whole lung irradiation (WLI) for pulmonary metastases. Methods and Materials: Retrospective review of all ES patients treated at age 18 or older with 12-15 Gy WLI for pulmonary metastases at a single institution between 1990 and 2014. Twenty-six patients met the study criteria. Results: The median age at WLI was 23 years (range, 18-40). The median follow-up time of the surviving patients was 3.8 years (range, 1.0-9.6). The 3-year cumulative incidence of pulmonary relapse (PR) was 55%, with a 3-year cumulative incidence of PR as the site of first relapse of 42%. The 3-year event-free survival (EFS) and overall survival (OS) were 38 and 45%, respectively. Patients with exclusively pulmonary metastases had better outcomes than did those with extrapulmonary metastases: the 3-year PR was 45% in those with exclusively lung metastases versus 76% in those with extrapulmonary metastases (P=.01); the 3-year EFS was 49% versus 14% (P=.003); and the 3-year OS was 61% versus 13% (P=.009). Smoking status was a significant prognostic factor for EFS: the 3-year EFS was 61% in nonsmokers versus 11% in smokers (P=.04). Two patients experienced herpes zoster in the radiation field 6 and 12 weeks after radiation. No patients experienced pneumonitis or cardiac toxicity, and no significant acute or late sequelae were observed among the survivors. Conclusion: WLI in adult patients with ES and lung metastases is well tolerated and is associated with freedom from PR of 45% at 3 years. Given its acceptable toxicity and potential therapeutic effect, WLI for pulmonary metastases in ES should be considered for adults, as it is in pediatric patients. All patients should be advised to quit smoking before receiving WLI

    Brain metastases are a common complication of cancer and occur in about 15-40% of patients with malignancies. The aim of this retrospective study was to differentiate between metastases from different primary tumors/CNS lymphyomas using morphologic criteria, fractional anisotropy (FA) and apparent diffusion coefficient (ADC). Morphologic criteria such as hemorrhage, cysts, pattern of contrast enhancement and location were reported in 200 consecutive patients with brain metastases/primary CNS lymphomas. FA and ADC values were measured in regions of interest (ROIs) placed in the contrast-enhancing tumor part, the necrosis and the non-enhancing peritumoral region (NEPTR). Differences between histopathological subtypes of metastases were analyzed using non-parametric tests, decision trees and hierarchical clustering analysis. Significant differences were found in morphologic criteria such as hemorrhage or pattern of contrast enhancement. In diffusion measurements, significant differences between the different tumor entities were only found in ADC analyzed in the contrast-enhancing tumor part. Among single tumor entities, primary CNS lymphomas showed significantly lower median ADC values in the contrast-enhancing tumor part (ADC{sub lymphoma} 0.92 [0.83-1.07] vs. ADC{sub no} {sub lymphoma} 1.35 [1.10-1.64] P=0.001). Further differentiation between types of metastases was not possible using FA and ADC. There were morphologic differences among the main subtypes of brain metastases/CNS lymphomas. However, due to a high variability of common types of metastases and low specificity, prospective differentiation remained challenging. DTI including FA and ADC was not a reliable tool for differentiation between different histopathological subtypes of brain metastases except for CNS lymphomas showing lower ADC values. Biopsy, surgery and staging remain essential for diagnosis.

    To compare gadoxetic acid alone and combined gadoxetic acid/gadofosveset trisodium-enhanced liver MRI for detection of metastases and differentiation of metastases from haemangiomas. Ninety-one patients underwent gadoxetic acid-enhanced liver MRI before and after additional injection of gadofosveset. First, two readers retrospectively identified metastases on gadoxetic acid alone enhanced delayed hepatobiliary phase T1-weighted images together with all other MR images (dynamic images, T2-weighted images, diffusion-weighted images). Second, readers assessed additional T1-weighted images obtained after administration of gadofosveset trisodium. For both interpretations, readers rated lesion conspicuity and confidence in differentiating metastases from haemangiomas. Results were compared using alternative free-response receiver-operating characteristic (AFROC) and conventional ROC methods. Histology and follow-up served as reference standard. There were 145 metastases and 16 haemangiomas. Both readers detected more metastases using combined gadoxetic acid/gadofosveset (reader 1 = 130; reader 2 = 124) compared to gadoxetic acid alone (reader 1 = 104; reader 2 = 103). Sensitivity of combined gadoxetic acid/gadofosveset (reader 1 = 90 %; reader 2 = 86 %) was higher than that of gadoxetic acid alone (reader 1 = 72 %; reader 2 = 71 %, both P < 0.01). AFROC-AUC was higher for the combined technique (0.92 vs. 0.86, P < 0.001). Sensitivity for correct differentiation of metastases from haemangiomas was higher for the combined technique (reader 1 = 98 %; reader 2 = 99 % vs. reader 1 = 86 %; reader 2 = 91 %, both P < 0.01). ROC-AUC was significantly higher for the combined technique (reader 1 = 1.00; reader 2 = 1.00 vs. reader 1 = 0.87; reader 2 = 0.92, both P < 0.01). Combined gadoxetic acid/gadofosveset-enhanced MRI improves detection and characterization of liver metastases compared to gadoxetic acid alone. (orig.)

    Purpose: To examine the outcomes of patients with five or more brain metastases treated in a single session with stereotactic radiosurgery (SRS). Methods and Materials: Sixty-four patients with brain metastases treated with SRS to five or more lesions in a single session were reviewed. Primary disease type, number of lesions, Karnofsky performance score (KPS) at SRS, and status of primary and systemic disease at SRS were included. Patients were treated using dosing as defined by Radiation Therapy Oncology Group Protocol 90-05, with adjustments for critical structures. We defined prior whole-brain radiotherapy (WBRT) as WBRT completed >1 month before SRS and concurrent WBRT as WBRT completed within 1 month before or after SRS. Kaplan-Meier estimates and Cox proportional hazard regression were used to determine which patient and treatment factors predicted overall survival (OS). Results: The median OS after SRS was 7.5 months. The median KPS was 80 (range, 60-100). A KPS of {>=}80 significantly influenced OS (median OS, 4.8 months for KPS {<=}70 vs. 8.8 months for KPS {>=}80, p = 0.0097). The number of lesions treated did not significantly influence OS (median OS, 6.6 months for eight or fewer lesions vs. 9.9 months for more than eight, p = nonsignificant). Primary site histology did not significantly influence median OS. On multivariate Cox modeling, KPS and prior WBRT significantly predicted for OS. Whole-brain radiotherapy before SRS compared with concurrent WBRT significantly influenced survival, with a risk ratio of 0.423 (95% confidence interval 0.191-0.936, p = 0.0338). No significant differences were observed when no WBRT was compared with concurrent WBRT or when the no WBRT group was compared with prior WBRT. A KPS of {<=}70 predicted for poorer outcomes, with a risk ratio of 2.164 (95% confidence interval 1.157-4.049, p = 0.0157). Conclusions: Stereotactic radiosurgery to five or more brain lesions is an effective treatment option for patients with

    Full Text Available Abstract Background Despite the fact that metastases are the leading cause of colorectal cancer deaths, little is known about the underlying molecular changes in these advanced disease stages. Few have studied the overall gene expression levels in metastases from colorectal carcinomas, and so far, none has investigated the peritoneal carcinomatoses by use of DNA microarrays. Therefore, the aim of the present study is to investigate and compare the gene expression patterns of primary carcinomas (n = 18, liver metastases (n = 4, and carcinomatoses (n = 4, relative to normal samples from the large bowel. Results Transcriptome profiles of colorectal cancer metastases independent of tumor site, as well as separate profiles associated with primary carcinomas, liver metastases, or peritoneal carcinomatoses, were assessed by use of Bayesian statistics. Gains of chromosome arm 5p are common in peritoneal carcinomatoses and several candidate genes (including PTGER4, SKP2, and ZNF622 mapping to this region were overexpressed in the tumors. Expression signatures stratified on TP53 mutation status were identified across all tumors regardless of stage. Furthermore, the gene expression levels for the in vivo tumors were compared with an in vitro model consisting of cell lines representing all three tumor stages established from one patient. Conclusion By statistical analysis of gene expression data from primary colorectal carcinomas, liver metastases, and carcinomatoses, we are able to identify genetic patterns associated with the different stages of tumorigenesis.

  3. Effect of size of lymph node metastases on the radiation response: influence of misonidazole

    Courdi, A.; Malaise, E.P.

    1980-01-01

    Metastatic lymph nodes of EMT6 tumors growing in athymic nude mice were used at different sizes and their radiosensitivity was tested with the in vitro colony method. Following the administration of 1250 rad, the surviving fraction in air-breathing animals was found to be dependent on the size of these metastases, expressed either in weight or in cell yield per lymph node. The increasing radioresistance with increase in size was probably due to the presence of higher hypoxic fraction in big nodes (0.43 in nodes weighing more than 320 mg vs 0.10 in nodes less than 80 mg). The surviving fraction after irradiation in acutely hypoxic conditions (asphyxiated animals) or in fully oxygenated ones (in vitro) was not size dependent. Great variations were observed in the radiosensitivity of small metastatic nodes, whereas bigger metastases had a more homogeneous response. The effect of the radiosensitizer misonidazole at a dose of 0.3 mg/g was assessed on lymph node metastases of different sizes. In the presence of the drug, the survival level of big and small metastases differed by a factor of 2.2, as opposed to 4.3 in untreated metastases. This suggests that the radiosensitization is less pronounced in metastases containing a smaller hypoxic fraction

    Fifty-one patients with spinal multiple myeloma (MM) metastases were operated and followed between January 2004 and July 2014. The aim of this study was to consider the efficiency of surgical prognosis scores in the management of spinal metastases myelomas. The spine is the most common site of bone metastases in MM. Surgery in spine metastases MM is a matter of debate and its impact on the increase of a patient's survival time is not clear. Several surgical survival scores have been developed to determine the best treatment in these patients. We studied 51 patients operated for spinal MM metastases between January 2004 and July 2014. We determined the Tokuhashi and Tomita survival scores and compared them with documented patient survivals. The two scores were also compared with the International Staging System (ISS). Median survival (MS) was 108 months [standard deviation (SD) 62] for ISS I, 132.2 (SD 40) for ISS II, and 45.5 months (SD 16.3) for ISS III (P = 0.09). According to Tokuhashi survival score, 21 patients (41.2%) will survive 12 months. According to Tomita et al., 50 patients (98%) will survive >49.9 months and 1 patient (2%) spine surgical prognosis scores are not accurate and are not able to predict the survival of patients with spine myeloma metastases. Spine surgeons have to be guided not by the initial ISS stage but rather by spinal instability and neurological status. N/A.

    Purpose: To assess the survival of patients with hepatic uveal melanoma metastases undergoing sequential transarterial hepatic chemoperfusion. Materials and Methods: 61 patients (mean age, 60.3 {+-} 13.8y) underwent a total of 249 hepatic chemoperfusion procedures (mean: 4 chemoperfusion procedures; range, 1 - 7 chemoperfusion procedures; standard deviation, 2.3 chemoperfusion procedures). All patients started with melphalan. In the case of progressive disease, melphalan was replaced by a different chemoperfusion agent. 38 patients were treated with melphalan only, 23 patients were treated with a combination of melphalan and other drugs. The median overall survival time was calculated for the overall population and several sub-groups. Differences in the survival rate between the sub-groups were assessed for statistical significance. The complication rate was assessed. Results: The median overall survival of the entire population was 10 months. The patients in the subgroups with a maximum number of 9 hepatic metastases as well as the patients in the subgroup without extrahepatic metastases at the beginning of therapy survived significantly longer than patients with more than 9 metastases/extrahepatic metastases (p = 0.019, p = 0.008). One patient (0.4 %) died from liver failure after initial infusion of melphalan. Conclusion: Intraarterial sequential hepatic chemoperfusion offers a minimally invasive treatment in patients with hepatic uveal melanoma metastases with good survival times and an acceptable major complication rate.

    Full Text Available Abstract Background Malignant melanoma occurs infrequently in Taiwan. Once it has progressed into osseous metastases, the prognosis is poor. There are no reported clinical experiences of surgical management in this area. Methods To improve our understanding of the rare clinical experiences, we retrospectively investigated clinical characteristics, radiological findings, treatment modalities, survival outcomes and prognoses of 11 Taiwanese patients with osseous metastasis of melanoma treated surgically at two national medical centers, National Taiwan University Hospital and National Cheng Kung University Hospital from January 1983 to December 2006. Results Six patients suffered from acral-lentiginous melanoma. Nine patients sustained multiple osseous metastases and most lesions were osteolytic. Nine patients also had sustained metastases to other organs including liver, lungs, lymph nodes, brain and spleen. Second malignancies including lung cancer, thyroid papillary carcinoma, renal cell carcinoma and cervical cancer co-existed in four patients. The interval from the initial diagnosis of melanoma to the clinical detection of osseous metastases varied from 0–37.8 months (mean 9.75 months. Metastatic melanoma was invariably fatal; the mean survival time from bone metastases to death was 5.67 months. Conclusion Due to the high morbidity and poor survival of Taiwanese patients with osseous metastases of melanoma, surgical treatment should be directed towards pain relief and the prevention of skeletal debilitation in order to maintain their quality of life.

  7. Metastatic disease of the brain: extra-axial metastases (skull, dura, leptomeningeal) and tumour spread.

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

  8. Update on the prevention of local recurrence and peritoneal metastases in patients with colorectal cancer.

    The prevention of a disease process has always been superior to the treatment of the same disease throughout the history of medicine and surgery. Local recurrence and peritoneal metastases occur in approximately 8% of colon cancer patients and 25% of rectal cancer patients and should be prevented. Strategies to prevent colon or rectal cancer local recurrence and peritoneal metastases include cytoreductive surgery and hyperthermic perioperative chemotherapy (HIPEC). These strategies can be used at the time of primary colon or rectal cancer resection if the HIPEC is available. At institutions where HIPEC is not available with the treatment of primary malignancy, a proactive second-look surgery is recommended. Several phase II studies strongly support the proactive approach. If peritoneal metastases were treated along with the primary colon resection, 5-year survival was seen and these results were superior to the results of treatment after peritoneal metastases had developed as recurrence. Also, prophylactic HIPEC improved survival with T3/T4 mucinous or signet ring colon cancers. A second-look has been shown to be effective in two published manuscripts. Unpublished data from MedStar Washington Cancer Institute also produced favorable date. Rectal cancer with peritoneal metastases may not be so effectively treated. There are both credits and debits of this proactive approach. Selection factors should be reviewed by the multidisciplinary team for individualized management of patients with or at high risk for peritoneal metastases.

    The effect of 5 mg of intravenous diazepam (Valium) on contrast media-associated seizer incidence was studied in a randomized controlled trial involving 284 patients with known or suspected brain metastases undergoing cerebral computed tomography. Of these patients, 188 were found to have brain metastases, and it is estimated that for this subgroup prophylactic diazepam reduces the risk of contrast-assocated seizure by a factor of 0.26. Seizures occurred in three of 96 patients with metastases on diazepam and in 14 of 92 patients with metastases but without diazepam. Factors related to increased risk of contrast media-associated seizures are: (1) prior seizure history due to brain metatases and/or prior contrast, (2) progressive cerebral metastases, and (3) prior or concurrent brain antineoplastic therapy. Factors not related to an increased risk of these seizures are: (1) contrast media dosage, chemical composition, or osmolarity, (2) computed tomographic appearance of metastases, and (3) type of primary malignancy. Concomitant therapeutic levels of diphenylhydantoin (Dilantin) do not protect completely against contrast media-associated seizures. Pathophysiology of contrast media-associated seizures is discussed in view of the risk factors determined by this study

    Five cases of penile metastases are presented. Axial and sagittal T1-weighted and T2-weighted scans were performed in all patients. In some, coronal images were also obtained. The penile metastases were most often seen as discrete masses in the corpora cavernosa or corpus spongiosum. An atypical pattern of diffuse infiltration is also illustrated. Limitations of cavernosography, ultrasound (US) and computed tomography (CT) are discussed. The magnetic resonance (MR) features of penile metastases and possible role MR may have in the management of these patients are described. Metastatic deposits in the penis are uncommon. First described by Eberth in 1870 in a patient with a primary rectal carcinoma, there have since been over 300 cases reported in the literature. The imaging of penile metastases is, however, less clearly defined. Until now, cavernosography, ultrasound (US) and computed tomography (CT) have been used. These techniques have limitations. Only recently has magnetic resonance imaging (MRI) been employed. We describe five cases of penile metastases evaluated with MRI and discuss the role and features of penile metastases on MRI.

    Objective: To compare the diagnostic value of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the preoperative detection of colorectal liver metastases in diffuse fatty infiltration of the liver, associated with neoadjuvant chemotherapy. Materials and methods: Twenty preoperative tri-phasic MDCT (4-64-row, Siemens) and dynamic contrast-enhanced MRI (1.5 T or 3.0 T, Siemens) examinations of patients with colorectal cancer and liver metastases in diffuse steatosis were retrospectively evaluated. All patients underwent surgical resection for liver metastases (time interval 1-60 days). The amount of fatty infiltration of the liver was determined histopathologically by semi-quantitative percent-wise estimation and ranged from 25 to 75%. Results: Overall, 51 metastases were found by histopathology of the resected liver segments/lobes. The size of the metastases ranged from 0.4 to 13 cm, with 18 (35%) being up to 1 cm in diameter. In the overall rating, MDCT detected 33/51 lesions (65%), and MRI 45/51 (88%). For lesions up to 1 cm, MDCT detected only 2/18 (11%) and MRI 12/18 (66%). One false positive lesion was detected by MDCT. Statistical analysis showed that MRI is markedly superior to MDCT, with a statistically significant difference (p 1 cm. Conclusion: For the detection of colorectal liver metastases after neoadjuvant chemotherapy and consecutive diffuse fatty infiltration of the liver, MRI is superior to MDCT, especially for the detection of small lesions.

    In follow-up examinations of irradiated brain metastases conventional contrast-enhanced morphological MR imaging is often unable to distinguish between transient radiation effects, radionecrosis, and tumor recurrence. To evaluate changes of relative cerebral blood flow (rCBF) in irradiated brain metastases arterial spin-labeling techniques (ASL) were applied and compared to the outcome of 1 H MR spectroscopy and spectroscopic imaging ( 1 H MRS, SI). Patients and methods In 2 patients follow-up examinations of irradiated brain metastases were performed on a 1.5-T tomograph (average single dose: 20 Gy/80% isodose). Relative CBF values of gray matter (GM), white matter (WM), and metastases (Met) were measured by means of the ASL techniques ITS-FAIR and Q2TIPS. 1 H MRS was performed with PRESS 1500/135. In both patients with initially hyperperfused metastases (Met/GM >1) the reduction of rCBF after stereotactic radiosurgery indicated response to treatment - even if the contrast-enhancing region increased - while increasing rCBF values indicated tumor progression. The findings were confirmed by 1 H MRS, SI and subsequent follow-up. The ASL techniques ITS-FAIR and Q2TIPS are able to monitor changes of rCBF in irradiated brain metastases. The two cases imply a possible role for ASL-MR perfusion imaging and 1 H MR spectroscopy in differentiating radiation effects from tumor progression. (orig.) [de

    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.

    Metastases from ileal neuroendocrine tumors (NETs) to the myocardium are rare and generally seen in patients with widespread metastatic NET disease. The objectives of this investigation were to describe the frequency of intracardiac metastases in ileal NET patients examined by (68)Ga-DOTA-TOC-PET/CT and to describe the cases in detail. All (68)Ga-DOTA-TOC-PET/CT examinations performed at the Karolinska University Hospital since 2010 until April 2012 were reviewed. In all, 128 out of 337 examinations were in patients with ileal NETs. Four patients had seven myocardiac metastases, yielding a frequency of 4.3 % in patients with ileal NETs. One patient had cardiac surgery while three were treated with somatostatin analogs. The cardiac metastases did not affect the patients' activity of daily life. (68)Ga-DOTA-TOC-PET/CT is an established imaging modality in identifying cardiac metastases in ileal NETs. Prospective studies are needed to confirm the true clinical value of (68)Ga-DOTA-TOC-PET/CT in detecting cardiac metastases in both ileal and non-ileal NETs.

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

    Extra-axial intracranial metastases may arise through several situations. Hematogenous spread to the meninges is the most frequent cause. Direct extension from contiguous extra-cranial neoplasms, secondary invasion of the meninges by calvarium and skull base metastases, and migration along perineural or perivascular structures are less common. Leptomeningeal invasion gives rise to tumour cell dissemination by the cerebrospinal fluid (CSF), eventually leading to neoplastic coating of brain surfaces.

    Our understanding of the mechanism of cancer dormancy is emerging, but the underlying mechanisms are not fully understood. Here we analyzed mouse xenograft tumors derived from human breast cancer tissue and the human breast cancer cell line MDA-MB-231 to identify the molecules associated with cancer dormancy. In immunohistological examination using the proliferation marker Ki-67, the tumors included both proliferating and dormant cancer cells, but the number of dormant cells was remarkably increased when they metastasized to the lung. In the gene expression analysis of the orthotopic cancer cells by a single-cell multiplex real-time quantitative reverse transcription PCR followed by flow cytometric analysis, restrained cellular proliferation was associated with downregulation of the chemokine receptor CXCR4. In the immunohistological and flow cytometric analyses, the expression level of CXCR4 in the metastasized cancer cells was decreased compared with that in the cancer cells in orthotopic tumors, although the expression level of the CXCR4 ligand CXCL12 was not reduced in the lung. In addition, the proliferation of the metastasized cancer cells was further decreased by the CXCR4 antagonist administration. In the ex vivo culture of the metastasized cancer cells, the expression level of CXCR4 was increased, and in the xenotransplantation of ex vivo cultured cancer cells, the expression level of CXCR4 was again decreased in the metastasized cancer cells in the lung. These findings indicate that CXCR4 is downregulated in metastasized breast cancer cells and implicated in their dormancy. PMID:26083776

  18. Medulloblastoma in an Adult With Late Extraneural Metastases to the Mediastinum

    2014-04-01

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

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

    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.

    1980-01-01

    Im 1971 and 1972, liver scintiscanning with 99 technetium-S-colloid was carried through in 1,570 patients. Their referral diagnoses reflected almost the entire range of medical specialties. 501 patients suspected of carrying liver metastases of the most different kinds of primary tumors, and 122 patients with systemic diseases of supposedly hepatic participation could be selected. From these two collectives it was possible to isolate 218 and 45 patients whose scintigraphic diagnoses could be confirmed. Including the scintigraphically uncertain diagnoses, accuracy in the tumor patients was 87.61%, sensitivity was 90%, and specificity was 86.23%. Without the uncertain diagnoses accuracy was 93.90%, sensitivity 81.39% and specificity 98.34%. Including the scintigraphically uncertain findings, accuracy in the patients with systemic diseases was 77.77%, sensitivity was 50% and specificity was 96.29%. Without the uncertain diagnoses accuracy was 76.31%, sensitivity 25% and specificity 100%. The low sensitivity in systemic diseases, which was due to the rather large number of false-negative diagnoses, was particularly striking as compared to the high specificity. (orig./MG) [de

    Full Text Available Liver transplantation remains a controversial therapy for Neuroendocrine liver metastases (NLM, with coflicting suvival data reported. The aim was to assess the evolution of outcomes for patients transplanted for NLM in the US, both before and after the introduction of the MELD scoring system in 2002. The UNOS/OPTN database was reviewed to identify patients diagnosed with NLM who subsequently underwent a liver transplantation from 1988 to March 2011 (=184; Patient survival was determined using Kaplan-Meier methods and log-rank tests, and cox regression analysis was performed, using SPSS 15.0 (SPSS, Inc, Chicago, IL. The overall NLM patient survivals in the pre-MELD era were 79.5%, 61.4%, and 49.2% at 1, 3, and 5 years, respectively. After the introduction of the MELD score, NET/NLM patients had improved overall patient survivals at 1, 3, and 5 years of 84.7%, 65%, and 57.8%. Patients transplanted after 2002 had an improved survival outcome. Notably, the overall patient survival for NET is not significantly different when compared to the outcomes of patients transplanted for HCC, in the current era. This progress acknowleges the significant improvement in outcomes for NLM patients after liver transplantation and the potential for further gain in the survival of otherwise nonsurgical, terminal patients.

    To evaluate the clinical and sonographic (US) features of metastatic tumors from extramammary malignancies to the breast. This study included 23 patients with pathologically proven metastases in the breast. Two radiologists retrospectively analyzed the images from US (n = 23), mammography (n = 11), and MRI (n = 5) examinations according to BIRADS. Patients presented with a palpable mass or diffuse breast swelling (21/23) or were asymptomatic (2/23). Eighteen patients had solitary or multiple breast masses on US. The common US finding was an ovoid hypoechoic mass with a noncircumscribed margin. The final assessment categories were BIRADS 3 (probably benign finding) in 6 cases (25%) and BIRADS 4 (suspicious abnormality) in 18 cases (75%). In five patients, US displayed a diffuse infiltrative pattern without a focal lesion, which was categorized as BIRADS 4. Metastatic tumors in the breast have a wide range of sonographic appearances, with some resembling benign lesions. Any newly developed mass in a patient with a known history of extramammary malignancy, even with a probably benign US appearance, should undergo biopsy for pathologic confirmation.

    Background and purpose: To analyze the location of metastatic lymph nodes in seminoma patients relative to vascular and bony anatomy and conventional radiation fields. Materials and methods: Cross-sectional scans of 90 seminoma patients with infradiaphragmatic adenopathy were analyzed. The position of each node respective to vascular anatomy was transferred to a standardized template. Conventional radiation fields were overlaid on the template and locations of metastatic nodes were assessed. Results: One hundred and forty-five nodes were radiographically positive. Eighty-four percent, 9%, and 7% of nodes were located in the para-aortic, common iliac, and pelvic regions, respectively. Ninety-nine percent of nodes were within a 2.5 cm lateral and 2.1 cm anterior expansion of the aorta inferior to T12/L1. No radiographically positive nodes were identified within the renal hilum or superior to L1 in left-sided seminomas. For right-sided seminomas, no radiographically positive nodes were superior to L2. Three percent of all radiographically positive nodes would have been located outside of conventional and modified fields. Conclusions: Infradiaphragmatic nodal metastases from a contemporary cohort of seminoma patients localized to a smaller area than is targeted by conventional radiation fields. Modified treatment fields based on vascular, rather than bony, anatomy are smaller and may allow for a significant decrease in normal tissue irradiation and toxicity

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

    The patterns of nodal spread of nasopharyngeal carcinoma (NPC) have an important influence on treatment planning, but have not yet been fully addressed. We prospectively used MRI and FDG PET to document the patterns of nodal spread in NPC. One hundred and one patients with newly diagnosed NPC were studied with MRI and FDG PET. On MRI, nodes were considered as metastatic according to criteria regarding size, the presence of nodal necrosis, and extracapsular spread. FDG PET images were interpreted visually, and nodes were considered metastatic if they showed prominent FDG uptake against the background. Nodal metastases were found in 89 of our 101 patients. Analysis of the distributions of nodal metastases in these 89 patients showed that retropharyngeal nodes were less frequently involved than cervical nodes (82.0% vs 95.5%). The vast majority of cervical nodal metastases were to the internal jugular chain, including nodes at levels II, III, and IV, with decreasing incidences of 95.5%, 60.7%, and 34.8%, respectively. Level V nodal involvement was found in 27% of patients. Supraclavicular fossa nodal metastases were not uncommon and occurred in 22.5% of patients. Skip metastases in the lower-level nodes or supraclavicular fossa nodes occurred in 7.9% of patients. Mediastinal and abdominal metastatic adenopathy was present in 4.5% and 3.4% of patients, respectively, and was associated with advanced nodal metastasis in the supraclavicular fossa. Level VI (2.2%), level VII (1.1%), submandibular (2.2%), and parotid (3.4%) nodal metastases were uncommon and were always associated with advanced ipsilateral nodal metastases of the neck. We conclude that the combined use of FDG PET and MRI can comprehensively depict the pattern of nodal metastasis in NPC patients. Nodal metastases principally affected level II nodes, from which lymphatic spread extended down in an orderly manner to involve level III, level IV, and the supraclavicular fossa nodes, or extended posteriorly to

    It is a well-established fact that in squamous cell carcinoma cases, the presence of lymph node metastases decreased the 5-year survival rate by 50% and also caused the recurrence of the primary tumor with development of distant metastases. Till date, the predictive factors for occult cervical lymph nodes metastases in cases of tongue squamous cell carcinoma remain inconclusive. Therefore, it is imperative to identify patients who are at the greatest risk for occult cervical metastases. This study was thus performed with the aim to identify various histopathologic parameters of the primary tumor that predict occult nodal metastases. The clinicopathologic features of 56 cases of lateral tongue squamous cell carcinoma with cT1NoMo/cT2NoMo as the stage and without prior radiotherapy or chemotherapy were considered. The surgical excision of primary tumor was followed by elective neck dissection. The glossectomy specimen along with the neck nodes were fixed in formalin and 5 urn thick sections were obtained. The hematoxylin & eosin stained sections were then subjected to microscopic examination. The primary tumor characteristics that were analyzed include tumor grade, invading front, depth of tumor, lymphovascular invasion, perineural invasion and inflammatory response. The nodes were examined for possible metastases using hematoxylin & eosin followed by cytokeratin immunohistochemistry. A total of 12 cases were found with positive occult nodal metastases. On performing univariate analysis, the histopathologic parameters that were found to be statistically significant were lymphovascular invasion (p = 0.004) and perineural invasion (p = 0.003) along with a cut-off depth of infiltration more than 5 mm (p = 0.01). Histopathologic assessment of the primary tumor specimen therefore continues to provide information that is central to guide clinical management, particularly in cases of occult nodal metastases. Clinical significance The study highlights the importance of

    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.

    Full Text Available Colorectal carcinoma (CRC is one of the leading causes of cancer-related deaths worldwide. Alterations in keratin expression, including keratin 7 (K7, are frequent findings in multiple cancers, and they constitute a prognostic factor. The aim of our study was to evaluate the prognostic significance of K7 in the primary tumour and lymph node metastases in two separate cohorts of patients: the first one with lymph node involvement (LN+, 129 cases and the second one free of LN metastases (LN–, 85 cases. Keratin 7 expression in CRC was analysed on tissue microarrays with immunohistochemistry and evaluated using the h-score. In the LN+ group K7 positivity was identified in 7/129 (5.4% of primary tumours (PT and lymph node metastases (LNM; concordance between them was 94% ( 0.396. Keratin 7 was expressed in 8/85 cases (9.4% in the LN– group. K7 expression in LNM of the LN+ cohort correlated with shorter overall survival (OS (p = 0.047 and presence of distant metastases at diagnosis (p = 0.005. Expression of K7 in the primary tumour in both cohorts did not correlate with survival. We conclude that the status of K7 expression in metastatic lymph nodes from CRC is a poor prognostic factor.

    Recently, a high rate of brain metastases has been reported among patients with human epidermal growth factor receptor (HER2)-overexpressing metastatic breast cancer who were treated with trastuzumab. The present study examined risk factors for the development of brain metastasis in patients with HER2-overexpressing breast cancer who were treated with trastuzumab. We retrospectively reviewed 204 patients with HER-2-overexpressing breast cancer who were treated with a trastuzumab-containing regimen between 1999 and 2006. Patients with clinical symptoms were diagnosed as having brain metastases when brain magnetic resonance imaging (MRI) or a computed tomography (CT) scan revealed positive findings for brain metastases. The median follow-up time of this cohort was 53.6 months. Among the patients who received a trastuzumab-containing regimen, 74 patients (36.3%) developed brain metastases. The median survival from the diagnosis of brain metastases was 13.5 months (95% confidence interval [CI], 12.2-14.7 months). The median time interval between the beginning of trastuzumab treatment and the diagnosis of brain metastases was 13.6 months (range, 0.0-45.8 months). Among patients with brain metastases, the median overall survival period was 39 months. A multivariate logistic regression analysis showed that age (≤50 years), recurrent breast cancer, and liver metastases were significant risk factors for the development of brain metastases. Patients with HER2-overexpressing breast cancer treated with trastuzumab had a high incidence of brain metastases (36.3%). Routine screening for brain metastases 1 year after the start of trastuzumab treatment, may be warranted in younger patients (≤50 years) who had recurrent breast cancer with liver metastases.

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

    The O(6)-methylguanine-methyltransferase (MGMT) promoter methylation status is a predictive parameter for the response of malignant gliomas to alkylating agents such as temozolomide. First clinical reports on treating brain metastases with temozolomide describe varying effects. This may be due to the fact that MGMT promoter methylation of brain metastases has not yet been explored in depth. Therefore, we assessed MGMT promoter methylation of various brain metastases including those derived fr...

    Aberrant expression of E-cadherin has been associated with the development of metastases in patients with breast cancer. Even though the expression of E-cadherin has been studied in primary breast tumors, little is known about its expression at the distant metastatic sites. We investigate the relationship between E-cadherin expression in primary breast carcinoma and their distant, non-nodal metastases. Immunohistochemical analysis of E-cadherin was performed in tissues from 30 patients with primary invasive breast carcinoma and their distant metastases. E-cadherin expression was evaluated as normal or aberrant (decreased when compared with normal internal positive controls, or absent). Twenty-two (73%) invasive carcinomas were ductal, and eight (27%) were lobular. Of the primary invasive ductal carcinomas, 55% (12/22) had normal E-cadherin expression and 45% (10/22) had aberrant expression. All of the metastases expressed E-cadherin with the same intensity as (12 tumors) or with stronger intensity than (10 tumors) the corresponding primaries. Of the invasive lobular carcinomas, one of eight (12%) primary carcinomas and none of the metastases expressed E-cadherin in the cell membranes, but they accumulated the protein in the cytoplasm. Aberrant E-cadherin expression is frequent in invasive ductal carcinomas that progress to develop distant metastases. Distant metastases consistently express E-cadherin, often more strongly than the primary tumor. Invasive lobular carcinomas have a different pattern of E-cadherin expression, suggesting a different role for E-cadherin in this form of breast carcinoma

    To determine whether the inferior outcome noted with triple-negative breast cancer (TNBC) reflects a higher risk population among patients with breast cancer liver metastases. A total of 123 patients with breast cancer liver metastases diagnosed at Tianjin Medical University Cancer Hospital were included in this study. Breast cancer subtype was assigned using immunohistochemistry or fluorescence in situ hybridization: hormone receptor (HR) positive (+)/human epidermal growth factor receptor 2 (HER2) negative (-), HR+/HER2+, HR-/HER2+ and triple-negative subtype. Clinical features and survival were evaluated in different subtypes. The median age at breast cancer diagnosis was 47 years (range, 23-67 years). Breast cancer subtype was confirmed in all patients (39.8% with HR+/HER2-, 24.4% with HR+/HER2+, 15.3% with HR-/HER2+ and 20.3% with TNBC). The median overall survival after liver metastases was 29 months (range, 4-89 months), and the overall 1-, 2- and 3-year survival rate was 68.3, 48.0 and 34.1%, respectively. Survival was found to be impacted by breast cancer subtype (P = 0.001), and was shortest for patients with TNBC. Time to liver metastases (TTLM) less than 24 months and liver metastasis lesions ≥3 were found to be important predictors of poor survival after liver metastases (P = 0.009 and 0.001, respectively). The results indicate that clinical breast cancer subtype remains an independent prognostic predictor among patients with breast cancer liver metastases. Liver metastases arising from TNBC confers the worst prognosis, and novel agents capable of controlling intrahepatic and extrahepatic TNBC are needed.

    Surgical resection in combination with radiotherapy in selected cases remains the best option for patients with cerebral metastases. Postoperative relapse of brain metastases occurs frequently and can be reduced by postoperative whole-brain radiotherapy (WBRT). Continuous spread of tumor cells from the primary lesions is debated as a cause of recurrence. It is well known that in gliomas, infiltration takes place within the surrounding edema. Obviously, most brain metastases are usually associated with peritumoral edema, which may act as an indicator of infiltration and more aggressive tumor biology. Therefore, we aimed to investigate the correlation of tumor and edema volumes with overall survival in patients with cerebral metastases. A total of 143 patients diagnosed with brain metastasis (male:female=1.1:1) who underwent surgical resection were included retrospectively in this analysis. Clinical data were retrieved from electronic patient files. The volumes of tumor and edema calculated by manual delineation. The ratio of edema to tumor volume was calculated, leading to dichotomization of the patients. The median tumor volume was 20.1 cc (range=0.8-90.8 cc) and the median volume of edema 49.5 cc (range=0-179.9 cc). The volume of metastases did not significantly correlate with overall survival. The ratio of edema to tumor volume was also not a prognostic factor in terms of overall survival. Only surgical resection, preoperative recursive partitioning analysis class, and postoperative addition of WBRT, as well as female sex, demonstrated beneficial effects. The extent of edema surrounding cerebral metastases does not appear to influence overall survival in patients suffering from brain metastases, although it seems to be responsible for most of the patients' symptoms. The hypothesis that the extent of edema was disadvantageous concerning survival was supported by our data. Copyright© 2017, International Institute of Anticancer Research (Dr. George J. Delinasios

    Full Text Available Background: Papillary thyroid carcinoma is typical by regional lymph nodes metastases. Therefore we decided to analyse associated risk factors. Objective: In this retrospective study we focused on the incidence of metastatic involvement of the central compartment’s lymph nodes correlated with age, size of the primary tumour, infiltration of thyroid gland capsule, positive lymphangioinvasion in order to assess risk factors. Method: We analysed group of 156 patients with papillary carcinoma, who have undergone total thyroidectomy and bilateral elective central compartment neck dissection. We evaluated the occurrence of metastases, size, infiltration and lymphangioinvasion based on definitive histology of the whole group and separately for subgroups of patients under and over 45 years. Result: We found metastatic involvement in 88 (56.4% patients. When comparing the subgroups of patients under (73 patients and over 45 years (83 patients, we found metastases in 56 vs. 32 (76.7% vs. 38.6% patients. In the subgroup of younger patients we found significant higher incidence of metastases compared with the group of over 45 years, P < 0.001 (P = 0.000027. We found significant higher incidence of metastases in patients with positive capsule infiltration in the whole group, P < 0.001 (P = 0.00049; in the subgroup of under 45 years, P < 0.001 (P = 0.00091 and in patients with positive lymphangioinvasion in the whole group, P < 0.01 (P = 0.00177; in the subgroup of over 45 years, P < 0.001 (P = 0.0002. In patients with metastases we found tumour size ≥1cm more frequently in all groups. Conclusion: We recorded higher incidence of regional metastases in patients under 45 years, positive capsule infiltration, lymphangioinvasion. Age under 45 years itself does not correlate with less aggressive disease, to the contrary some of other analysed risk factors correlate with more aggressive disease.

    Adenocarcinoma of the lung with EML4-ALK translocation is a rare subtype of Non Small-Cell Lung Cancer (NSCLC) that has recently shown to benefit from treatment with crizotinib. Despite the concerns about the efficacy of crizotinib over cerebral metastases, some reports have described its activity, although always after local treatment with radiotherapy. Recently it has been reported activity of crizotinib over choroidal metastases, again after radiotherapy. Herein we report a case of activity of crizotinib over choroidal metastases not previously treated with radiotherapy. We suggest crizotinib may be active over choroidal metastases in a patient harboring ALK translocation with no need of radiotherapy.

    The poors outcomes associated with pancreatic cancer clearly reflect the advanced stage of disease at diagnosis for most patients. Through this lens, it is easy to lose sight of the fact that roughly 50% of patients with pancreatic cancer have no clinically detectable metastases at presentation. Herein, we discuss how patients with localized pancreatic cancer are currently managed. The primary goal of care for patients with resectable and borderline-resectable tumors is cure, facilitated by achieving margin-negative resection of the primary disease and delivering effective adjuvant and/or neoadjuvant therapy. For patients with locally advanced disease, the focus is on limiting local progression and outgrowth of metastatic disease and maintaining quality of life. Although it was once a centerpiece of therapy for localized pancreatic cancer, the value and place of radiation therapy in the treatment algorithm is now under increased scrutiny. In contrast, given its value as demonstrated in multiple prospective trials, chemotherapy is an established part of the treatment paradigm for all patients. With the demonstration that cytotoxic combinations such as fluorouracil, leucovorin, irinotecan, and oxaliplatin as well as gemcitabine/nab-paclitaxel are active in the metastatic setting, these agents are now being studied in patients with localized disease. The neoadjuvant setting provides a particularly favorable setting for evaluating new systemic strategies. Given the array of new targets, including immunomodulatory approaches, there is reason for optimism that we can markedly improve survival for all patients with pancreatic cancer and enter an era in which surgery with curative intent actually fulfills this goal on a much more regular basis. © 2015 by American Society of Clinical Oncology.

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

    Background. The humerus is a common localisation of cancer metastases. The restoration of anatomical order and tumor resection within humerus is important for patients quality of everyday life and for their pain relief. The surgical treatment is one of the most important part of the whole oncological ways of tratment. The study objective was a clinical assesment of tumor resection and reconstruction within humerus according to matastasis localisation and the choice of surgical technique. Material and methods. In the years 1999-2002 19 patients underwent surgery due to pathological fracture or/and cancer metastasis within humerus. The shaft localisation of the tumor was found in 8 cases and in 11 patients the metastatic foci were found in proximnal diaphysis. In patients with proximal diaphysis localisation of the tumor the partial resection with subsequent joint exchange procedure was made. The humeral shaft metastatic cancer changes were treated by the segmental resection with subsequent surgical cement filling or auto/allogenical bone grafting combined with intramedullary nail or AO/ASIF plate stabilisation. The average follow-up period was 8,5 months. Results. In patients after resection with shoulder joint alloplasty according to the Enneking test a very good result was found in 7 and very good in 4 cases. In patients with femoral shaft metastatic tumor locaslisation, 6 good and 2 fair results were found. In 1 patient after 2 months rehabilitation a reoperation was needed due to the mechanical destabilisation. The best results were found in patients after intramedullary nailing.An acute soft tissue inflamation requiering surgical treatment was found in 1 patient after shoulder joint replacement. Conclusions. After clinical analysis of the material we highly recomend the partial humeral bone resection with subsequent shoulder alloplasty in patients with proximal humeral diaphysis metastatic localisation. In cases with shaft localisation a better results were

    Yttrium-90 (Y-90) radioembolization is an emerging treatment option for unresectable neuroendocrine liver metastases (NELM). However, the data regarding this treatment are currently limited. This study evaluates the efficacy and tolerability of Y-90 radioembolization and identifies prognostic factors for radiographic response and survival. Thirty-eight patients underwent Y-90 radioembolization for NELM at our institution between April 2004 and February 2012. Patients were assessed radiographically (RECIST criteria, enhancement), serologically, and clinically at 1month, and then at every 3months after treatment for tumor response, toxicity, and survival outcomes. Median length of follow-up was 17.0months (IQR, 9.0-37.0). Median survival was 29.2months. Three patients (9%) had a radiographic complete response to treatment, 6 (17%) had a partial response, 21 (60%) had stable disease, and 5 (14%) developed progressive disease. Two factors were significantly associated with a good radiographic response (complete/partial response): islet cell histological subtype (p=0.043) and hepatic tumor burden ≥33% (p=0.031). Multivariate analysis revealed that patients requiring multiple Y-90 treatments (HR 2.9, p=0.035) and patients who had previously failed systemic therapy with octreotide/chemotherapy (HR 4.4, p=0.012) had worse survival. Grade 3 serologic toxicity was observed in 2 patients (5%; hyperbilirubinemia, elevated alkaline phosphatase) after treatment. Grade 3 non-serologic toxicities included abdominal pain (11%), fatigue (11%), nausea/vomiting (5%), ascites (5%), dyspnea (3%), diarrhea (3%), and peripheral edema (3%). No grade 4 or 5 toxicity was reported. Y-90 radioembolization is a promising treatment option for inoperable NELM and is associated with low rates of grade≥3 toxicity. Copyright © 2016.

    Purpose: To review experiences in the treatment of regionally advanced melanoma to the neck and/or parotid with emphasis on the role of adjuvant radiotherapy. Patients and Methods: Clinical and histopathologic data, treatment details, and outcomes in patients treated during the period 2000-2006 at the Institute of Oncology, Ljubljana, Slovenia, were reviewed. Results: A total of 40 patients with 42 dissections underwent surgery, and 43 patients with 45 dissections received irradiation postoperatively to a median equivalent dose (eqTD 2 : 2 Gy/fraction, 1 fraction/day, 5 fractions/week) of 60 Gy (range, 47.8-78.8). Regional control 2 years after surgery was 56% (95% confidence interval [CI] 40-72%) and after postoperative radiotherapy 78% (CI 63-92%) (p = 0.015). On multivariate analysis, postoperative radiotherapy (yes vs. no: hazard ratio [HR] 6.3, CI 2.0-20.6) and sum of the risk factors present (i.e., risk factor score; HR 1.7 per score point, CI 1.2-2.6) were predictive for regional control. On logistic regression testing, the number of involved nodes was associated with the probability of distant metastases (p = 0.021). The incidence of late toxicity did not correlate with the mode of therapy, eqTD 2 , or fractionation pattern. Conclusions: Adjuvant radiotherapy has the potential to compensate effectively for the negative impact of adverse histopatologic features to disease control in a dissected nodal basin. More conventionally fractionated radiotherapy regimens using fraction doses of 2-2.5 Gy, with cumulative eqTD 2 ≥60 Gy, are recommended. The number of involved lymph nodes is proposed as an additional criterion for limiting the implementation of adjuvant irradiation.

    Although clinically evident metastases of nonthyroid malignancies (NTMs) to the thyroid gland are uncommon, it is important to suspect them in patients who present with a new thyroid mass and a history, however far back, of prior malignancy. In fact, metastases from NTMs to the thyroid gland have been reported in 1.4%-3% of all patients who have surgery for suspected cancer in the thyroid gland. Here we review the literature over the last decade regarding this topic. Based on recent literature, the most common NTMs that metastasize to the thyroid gland are renal cell (48.1%), colorectal (10.4%), lung (8.3%), and breast carcinoma (7.8%), and sarcoma (4.0%). Metastases of NTMs to the thyroid are more common in women than men (female to male ratio=1.4 to 1) and in nodular thyroid glands (44.2%). The mean and median intervals between diagnosing NTMs and their metastases to thyroid gland are 69.9 and 53 months, respectively. In 20% of cases the diagnosis of the NTM and its metastases to the thyroid was synchronous. Recent reports indicate that there is a higher frequency of sarcoma metastasizing to the thyroid gland than reported in prior years. Fine-needle aspiration biopsy (FNAB) of thyroid masses is useful in diagnosis of thyroid metastases. However, this requires information about the NTM so that the proper antibodies can be used for immunohistochemical analysis; therefore it is of lesser utility if the NTM is occult. In patients with preexisting thyroid pathology the FNAB diagnosis can be more difficult due to more than one lesion being present. It is important to keep in mind that the thyroid gland can be a site of metastases for a variety of tumors when evaluating a thyroid nodule, especially in a patient with a prior history of malignancy. In patients with thyroid lesions and a history of malignant disease, regardless of time elapsed since the initial diagnosis of the primary neoplasm, disease recurrence or progression of malignancy must be considered until

    Factors affecting the effect of {sup 131}I 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 {sup 131}I therapy. The effect of {sup 131}I treatment and the prognostic values of the following variables were examined: sex, age at the time of {sup 131}I treatment, histologic type of cancer, size of pulmonary metastases on CT, total-body scintigraphy with {sup 201}Tl and {sup 131}I, serum thyroglobulin levels and presence of metastases in distant sites other than lung. The effect of {sup 131}I 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 {sup 131}I dose scans revealed detectable uptake in 25 of 51 patients. Therapeutic {sup 131}I 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 {sup 131}I 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 {sup 131}I uptake than papillary cancer. Of all the variables studied, the best prognosis for survival was demonstrated by increased {sup 131}I uptake in pulmonary metastases. These results indicate that age, {sup 131}I uptake and presence of other metastases are important factors in predicting the effect of {sup 131}I treatment for pulmonary metastases of

    Full Text Available We report a case of penile metastases from recurrent prostatic adenocarcinoma that was the first sign of a widespread metastatic disease in the absence of any increase in prostate-specific antigen (PSA level. In April 2011, an 80-year-old man presented to our Radiotherapy Unit with multiple palpable hard nodules in the penis, dysuria, and moderate perineal pain, 7 years after he had received radiotherapy for prostate cancer. Nodules in the penis had appeared in February 2011. The ultrasound and magnetic resonance (MR imaging suggested the diagnosis of multiple penile metastases. A total body computed tomography scan revealed a systemic spread of the disease, with multiple metastases in the liver, bones, and lungs. PSA level was 0.126 ng/ml. A fine needle aspiration biopsy of the liver lesion was undertaken, and the histopathologic examination revealed the prostatic origin of the metastases, so androgen deprivation therapy was started. The diagnosis of metastases should be considered in a patient with prior history of prostate malignancies presenting with solid nodules in the penis, even if the PSA level is low.

    Small focal ischaemic brain lesions are said to be easy to identify in the acute stage and to differentiate from older lesions using diffusion-weighted imaging (DWI). Brain metastases are common and the aim of this study was to evaluate the risk of misinterpretation as ischaemic lesions in a standard MRI protocol for clinical stroke. Of 26 patients investigated with MRI for possible metastases, 12 did have metastatic brain lesions, including most of the common tumours. On a 1.5 tesla imager, we obtained DWI, plus T2- and T1-weighted images, the latter before and after triple-dose contrast medium. Well-circumscribed brain lesions with a decreased apparent diffusion coefficient and a slightly or moderately increased signal on T2-weighted images were found in patients with metastases from a small-cell bronchial carcinoma and a pulmonary adenocarcinoma. The same features were also found in metastases from a breast carcinoma but the lesions were surrounded by oedema. With a standard DWI protocol, the features of common brain metastases may overlap with those of small acute and subacute ischaemic lesions. (orig.)

    Objective: To study the clinical characteristics of pulmonary metastases (PM) from differentiated thyroid cancers (DTC) and 131 I therapeutic efficacy. Methods: Of 42 DTC patients with PM, 12 were male and 30 female. The clinical diagnosis of PM derived evidence from patients' history, lab tests, X-ray examination and 131 I whole body scan ( 131 I-WBS). 131 I treatment protocol was subject to each patient's condition and 131 I-WBS results, with 152.6±14.3 mCi each time and periodical duration 137±21 days. The follow-up time ranged from 1 to 10 yrs. Results: Before the onset of 131 I treatment, 18 patients with PM showed no pulmonary symptoms, but 14 came up with mild symptoms and other 10 severe; the latter aged elder than the former. 22 patients (52.4%) were cured after 131 I treatment, and other 9 patients' condition become favorable or stable. Metastases other than PM were found in 34 cases for which 131 I treatment were more effective on the cervical and mediastinum metastases than on bone metastases (p 131 I occurred in 4 cases. Conclusion: Absence of pulmonary symptoms is an important characteristic of early PM from DTC. Early PM is well related with favorable outcomes from 131 I treatment. Other elements affecting 131 I treatment results include patients' age, other metastases and severities of adverse reaction to 131 I therapy

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

    A 64-year-old woman underwent polypectomy for a rectal polyp (Isp). Pathological findings were invasion of the submucosa (3,500 μm diameter), and she underwent anterior resection for rectal cancer (RS, pT1b, pN0, cM0, Stage I ) without adjuvant chemotherapy. Lung masses were found in her right (8 mm) and left lung (7 mm). The tumors enlarged during the 4 month follow-up period. We decided to perform left partial pneumonectomy. The tumor was diagnosed as a lung metastasis from colon cancer by pathology. Because the right tumor was located towards the center, performing right pneumonectomy would have been quite invasive and we feared occult metastases. We decided to apply SRT (50 Gy) to the right tumor. The tumor shrunk and became a scar after treatment. There were no complications such as radiation pneumonitis. The patient was in good health without any recurrence for 12 months after SRT. Surgical resection is an optimal method to control lung metastasis from colon cancer if the lesion is operable. However, in the case of a tumor centrally located, surgical resection may cause deterioration of lung function. There are also cases with contraindications for surgery due to co-morbidities. In addition, there is no consensus on observation periods to exclude occult metastases. SRT can be an effective treatment for lung metastases from colon cancer when there are bilateral lung metastases and no metastases outside the lungs. (author)

    The liver is the most common site of metastatic tumour deposits. Hepatic metastases are the major cause of morbidity and mortality in patients with gastrointestinal carcinomas and other malignant tumours. The rationale and results for interventional therapeutic techniques in the treatment of liver metastases are presented. For the treatment of patients with irresectable liver metastases, alternative local ablative therapeutic modalities have been developed. Technique and results of local interventional therapies are presented such as microwave-, radiofrequency (RF)- and ultrasound ablation, and laser-induced interstitial therapy (LITT), cryotherapy and local drug administration such as alcohol injection, endotumoral chemotherapy and regional chemoembolisation. In addition to cryotherapy, all ablative techniques can be performed percutaneously with low morbidity and mortality. Cryotherapy is an effective and precise technique for inducing tumour necrosis, but it is currently performed via laparotomy. Percutaneous local alcohol injection results in an inhomogeneous distribution in liver metastases with unreliable control rates. Local chemotherapeutic drug instillation and regional chemoembolisation produces relevant but non-reproducible lesions. Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate. Interventional therapeutic techniques of liver metastases do result in a remarkable local tumour control rate with improved survival results. (orig.) With 5 figs., 1 tab., 43 refs.

    Cerebral metastases appear frequently and necessitate therapeutic measures. The authors report the incidence and particularities as well as the different modes of formation of metastases in the central nervous system. Surgical procedure should be carried out in case of favorable solitary metastases, young patients, and unknown primary tumors. Radiotherapy, which has proved for 30 years to be a valuable treatment method, has to be applied in a modified form in every case. Furthermore, the possibilities of chemotherapy should be studied and applied in a more intensive manner than hitherto. The chance of a one-year survival time is 22 to 44% for those patients presenting with an easily operable tumor. For the total group of radiotherapy patients suffering from various tumor types and generalized metastases, this rate is between 12% and 16%. Despite the short survival times, one should not forget that radiotherapy can produce many successful long-term results in case of cerebral metastases. Therapeutic nihilism is not the right attitude towards this problem.

  16. Whole-brain radiation therapy for brain metastases: detrimental or beneficial?

    2015-01-01

    Stereotactic radiosurgery is frequently used, either alone or together with whole-brain radiation therapy to treat brain metastases from solid tumors. Certain experts and radiation oncology groups have proposed replacing whole-brain radiation therapy with stereotactic radiosurgery alone for the management of brain metastases. Although randomized trials have favored adding whole-brain radiation therapy to stereotactic radiosurgery for most end points, a recent meta-analysis demonstrated a survival disadvantage for patients treated with whole-brain radiation therapy and stereotactic radiosurgery compared with patients treated with stereotactic radiosurgery alone. However the apparent detrimental effect of adding whole-brain radiation therapy to stereotactic radiosurgery reported in this meta-analysis may be the result of inhomogeneous distribution of the patients with respect to tumor histologies, molecular histologic subtypes, and extracranial tumor stages between the groups rather than a real effect. Unfortunately, soon after this meta-analysis was published, even as an abstract, use of whole-brain radiation therapy in managing brain metastases has become controversial among radiation oncologists. The American Society of Radiation Oncology recently recommended, in their “Choose Wisely” campaign, against routinely adding whole-brain radiation therapy to stereotactic radiosurgery to treat brain metastases. However, this situation creates conflict for radiation oncologists who believe that there are enough high level of evidence for the effectiveness of whole-brain radiation therapy in the treatment of brain metastases

    Most men with metastatic castration-resistant prostate cancer (CRPC) have biochemical response to docetaxel, but the objective response rate is low. Liver metastases are uncommon with CRPC and associated with shorter survival. More active treatment might benefit these patients. Epirubicin, cisplatin and flurouracil (ECF) is a standard regimen for gastric cancer and response in CRPC liver metastases has been reported. We reviewed our experience with ECF in CRPC with the primary objective of determining its anti-tumour activity in patients with liver metastatic CRPC. Men with CRPC treated with ECF were identified from electronic databases and data were extracted from medical records. Men with tumours showing neuroendocrine features were excluded. In total, we identified 14 CRPC patients treated with ECF were identified, of which 8 had liver metastases. The median age was 56 (range: 42-76) and all had multiple poor prognostic features. A median of 6 cycles of ECF were administered (range: 1-10) and toxicities were similar to previous reports. Of the 8 patients with liver metastases, 5 had partial remission. ECF was highly active in this small selected group of younger men with liver metastases from CRPC and multiple poor prognostic features. Despite important limitations, this is the third report of high objective response rates with ECF in CRPC. Objective response rates are low with current monotherapies. A higher probability of ORR is preferred for critical organ disease, therefore the anti-tumour activity should encourage testing of ECF in comparison to the most active current therapies.

    Phenotypical change in metastatic breast carcinoma has widely been accepted as an inherent biological feature rather than technical fault. We analyzed the immunohistochemical phenotype and histopathological features of 25 primary breast carcinomas and 90 corresponding distant metastases in 23 organs retrospectively. Histological slides were reviewed for prognostic and predictive factors. Overall, metastases were more similar to each other and often differed from the primary tumor. We created a 3-step grouping system based on the localization of metastases. Regions: tumors metastasizing to the abdominal region were likely to lose ER (p = 0.002); we detected loss of PR in metastases to the thorax (p = 0.039) and abdomen (p < 0.001). Organ systems: loss of ER and PR was observed in metastases to the gastrointestinal system (p = 0.026 and p = 0.001, respectively), in the respiratory system only the loss of PR was significant (p = 0.05). Individual organs: the primaries were likely to lose the hormone receptors in liver metastases (ER p = 0.026; PR p = 0.004). In lung metastases only loss of PR was apparent (p = 0.049). We did not observe significant change in HER2 status, regarding Ki67 change occurred only in bone metastases compared to the primary (p = 0.048). 7/25 patients' distant metastases had heterogeneous immunoprofiles. The later the metastasis was discovered the more likely it had a differing IHC profile compared to the primary tumor, patients who had longer OS had a higher chance to develop a discordant metastasis. Immunoprofile of metastases may differ from primary breast cancer and from each other, probably resulting in different response to therapy.

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

    We report a case of a 53-year-old man who presented with two nodules in the lower lobe and one nodule in the upper lobe of the right lung almost 7 years after radical prostatectomy for pT3aN0M0, Gleason 4+5 disease, without evidence of osseous or lymphatic spread. Surgical resection of the lower lung nodules confirmed metastases, but prostate-specific antigen did not drop to undetectable levels. Isolated pulmonary metastases from prostate cancer are rare with only 33 previously described cases in the English-language literature, 18 of which were solitary metastases. We review the principles of management, including metastasectomy and long-term prognosis. PMID:22154171

    Metastases to the oral cavity are uncommon, accounting for only 1% of all oral malignant tumors. When they occur they mostly originate from primary tumors of the lungs, kidney, breast and prostate. Oral metastases from the primary colorectal carcinoma are much more infrequent. We present an unusual case of a 78-year-old man with a soft tissue oral metastasis originating from the primary colorectal carcinoma.The patient was referred to the Department of Otorhinolaryngology, Head and Neck Surgery with an intraoral mass on the right side of the maxilla. The diagnosis was confirmed by histopathologic examination and immunohistochemical analysis. Oral metastases occur rarely and often can mimic much more common benign lesions, therefore they should be considered as a possibility in a differential diagnosis.

    Computed tomography is the imaging modality of choice for detection or exclusion of pulmonary metastases. In most cases these are spheric, multiple, bilateral, and located in the peripheral areas of the middle and lower fields of the lungs. Differential diagnosis of solitary pulmonary nodules is difficult. Evaluating whether they are malignant or benign is insufficient despite the application of multiple CT criteria. Spiral computed tomography acquiring an imaging volume in a breathhold has led to significant improvement in the sensitivity of detecting pulmonary nodules. Imaging protocols are presented, and the influence of the different parameters is discussed. Although not all pulmonary metastases may be detected with spiral computed tomography, it is the most important examination when considering pulmonary metastasectomy. Computed tomography is the imaging modality of choice when monitoring pulmonary metastases during systemic therapeutic regimens by measuring all nodules or 'indicator lesions'. (orig.) [de

    Full Text Available Prostate cancer is the most common solid tumor malignancy worldwide with an estimated 180,000 new cases of prostate cancer and 26,000 deaths in the USA in 2016. Although significant advances in the treatment of prostate cancer have recently been made, the treatment of metastatic disease remains a challenge. With visceral metastases marking more advanced tumor stages, liver involvement is associated with the worst prognosis. So far, no locoregional treatment regimens for the management of liver metastases of prostatic cancer exist. Herein, we report for the first time a successful treatment of hepatic metastases of prostatic cancer using radioembolization with selective intra-arterial administration of Yttrium-90 resin microspheres.

    To report two cases of late metastases of clear cell renal cell carcinoma. Two patients, a male and a female with history of nephrectomy 17 and 16 years before for renal cell carcinomas, presented new tumours in the thyroid and pancreas, which were excised. Pathology reported that both lesions were clear cell tumours and immunohistochemically they were consistent with metastases from clear renal cell carcinomas. 1) Previous history of any type of carcinoma should suggest the possibility of metastases when facing a thyroid or pancreatic nodule. 2) All-life follow-up should be made, nephrectomy (resection) for a renal cell carcinoma. 3) In the presence of a clear cell tumour of the thyroid or pan-creatic glands, the differential diagnosis must always include metastatic renal cell carcinoma. 4) The treatment of choice is surgical resection.

  7. Understanding the Progression of Bone Metastases to Identify Novel Therapeutic Targets

    2018-01-01

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

    Pseudo-Meigs' syndrome associated with colorectal cancer is extremely rare. We report here a case of pseudo-Meigs' syndrome secondary to metachronous ovarian metastases from colon cancer. A 65-year-old female with a history of surgery for transverse colon cancer and peritoneal dissemination suffered from metachronous ovarian metastases during treatment with systemic chemotherapy. At first, neither ascites nor pleural effusion was observed, but she later complained of progressive abdominal distention and dyspnea caused by rapidly increasing ascites and pleural effusion and rapidly enlarging ovarian metastases. Abdominocenteses were repeated, and cytological examinations of the fluids were all negative for malignant cells. We suspected pseudo-Meigs' syndrome, and bilateral oophorectomies were performed after thorough informed consent. The patient's postoperative condition improved rapidly after surgery. We conclude that pseudo-Meigs' syndrome should be included in the differential diagnosis of massive or rapidly increasing ascites and pleural effusion associated with large or rapidly enlarging ovarian tumors.

    Pain and quality of life following palliative radiotherapy of bone metastases Background and purpose: palliative irradiation is used to provide pain relief and to increase quality of life. Most studies exclude patients with advanced cancer disease and, therefore, a positive selection results. This prospective clinical study investigates the effect of palliative radiotherapy on pain and quality of life of patients with painful bone metastases. Patients and methods: 263 patients with bone metastases due to advanced cancer were observed with respect to pain and quality of life during a 2-month course of radiotherapy. Missing data were substituted by the LOCF method (last observation carried forward) to prevent a biased reduction of data. Results: radiotherapy resulted in pain relief. In the complete group, pain medication was not increased. Quality of life was not affected positively. Side effects of radiotherapy increased remarkably. Conclusion: Radiotherapy leads to pain relief. However, risks and benefits must be considered critically due to side effects. (orig.)

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

    Contrast enhanced ultrasound (CEUS) is an imaging technique which appeared on the market around the year 2000 and proposed for the detection of liver metastases in gastrointestinal cancer patients, a setting in which accurate staging plays a significant role in the choice of treatment. A total of 109 patients with colorectal (n = 92) or gastric cancer prospectively underwent computed tomography (CT) scan and conventional US evaluation followed by real time CEUS. A diagnosis of metastases was made by CT or, for lesions not visible at CT, the diagnosis was achieved by histopathology or by a malignant behavior during follow-up. Of 109 patients, 65 were found to have metastases at presentation. CEUS improved sensitivity in metastatic livers from 76.9% of patients (US) to 95.4% (p cancer. Findings at CEUS and CT appear to be complementary in achieving maximum sensitivity.

  15. Skeletal metastases - the role of the orthopaedic and spinal surgeon.

    Science.gov (United States)

    Eastley, Nicholas; Newey, Martyn; Ashford, Robert U

    2012-09-01

    Developments in oncological and medical therapies mean that life expectancy of patients with metastatic bone disease (MBD) is often measured in years. Complications of MBD may dramatically and irreversibly affect patient quality of life, making the careful assessment and appropriate management of these patients essential. The roles of orthopaedic and spinal surgeons in MBD generally fall into one of four categories: diagnostic, the prophylactic fixation of metastatic deposits at risk of impending fracture (preventative surgery), the stabilisation or reconstruction of bones affected by pathological fractures (reactive surgery), or the decompression and stabilisation of the vertebral column, spinal cord, and nerve roots. Several key principals should be adhered to whenever operating on skeletal metastases. Discussions should be held early with an appropriate multi-disciplinary team prior to intervention. Detailed pre-assessment is essential to gauge a patient's suitability for surgery - recovery from elective surgery must be shorter than the anticipated survival. Staging and biopsies provide prognostic information. Primary bone tumours must be ruled out in the case of a solitary bone lesion to avoid inappropriate intervention. Prophylactic surgical fixation of a lesion prior to a pathological fracture reduces morbidity and length of hospital stay. Regardless of a lesion or pathological fracture's location, all regions of the affected bone must be addressed, to reduce the risk of subsequent fracture. Surgical implants should allow full weight bearing or return to function immediately. Post-operative radiotherapy should be utilised in all cases to minimise disease progression. Spinal surgery should be considered for those with spinal pain due to potentially reversible spinal instability or neurological compromise. The opinion of a spinal surgeon should be sought early, as delays in referral directly correlate to worse functional recovery following intervention

    Ovarian metastases from colorectal cancer (OM-CRC) often are unresponsive to chemotherapy and are associated with poor survival. To the authors' knowledge, the clinicopathologic and genomic predictors of OM-CRC are poorly characterized and optimal clinical management remains unclear. Women with a histopathological diagnosis of OM-CRC who were treated at Memorial Sloan Kettering Cancer Center from 1999 to 2015 were identified. Next-generation somatic mutation profiling (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets [MSK-IMPACT]) was performed on 38 OM-CRC cases, including 21 matched tumor pairs/trios. Regression models were used to analyze variables associated with progression-free survival and overall survival (OS). Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS), SMAD family member 4 (SMAD4), and neurotrophic receptor tyrosine kinase 1 (NTRK1) mutations were more frequent in cases of OM-CRC than in instances of CRC occurring without OM. SMAD4 and lysine methyltransferase 2D (KMT2D) mutations were associated with reduced OS. Matched multisite tumor sequencing did not identify OM-specific genomic alterations. Of the 195 patients who underwent oophorectomy for OM-CRC (median age, 49 years with a progression-free survival of 9.4 months and an OS of 23 months from oophorectomy), 76% had extraovarian metastasis (EOM). In multivariable analysis, residual disease after surgery (R2 resection) was associated with worse survival. Patients with EOM were less likely to achieve R0/R1 surgical resection status (complete macroscopic resection without clinical/radiological evidence of disease) (48% vs 94%). However, if R0/R1 resection status was achieved, both patients with (35.9 months vs 12 months) and without (43.2 months vs 14.5 months) EOM were found to have better OS. Among 114 patients with R0/R1 resection status, 23 (20%) had no disease recurrence, including 10 patients (9%) with > 3 years of follow-up. Loss

    We determined the incidence of isolated pelvic metastases at restaging computed tomography (CT) in patients with testicular germ cell tumors to consider if imaging the pelvis could be omitted. After receiving IRB approval for this HIPAA-compliant retrospective study, medical records of 560 men (mean age 32.8) with 583 testicular germ cell tumors who underwent 3683 restaging CT scans of the abdomen and pelvis were reviewed to determine the proportion of patients with metastatic disease in the pelvis alone, as verified by histology or by resolution after therapy. Chi-square statistical analysis tested the association between factors currently thought to predispose patients to pelvic metastases. Patients were also categorized by clinical stage, tumor histology, and initial treatment. Isolated pelvic metastases were detected in nine (1.6%) of 560 men. Neither bulky abdominal disease (p=0.85) nor extratesticular invasion by the primary tumor (p=0.37) were statistically significant in predicting which patients were more likely to have isolated pelvic metastases. Among the nine patients with isolated pelvic recurrence, only three (0.7%) of 408 men with no known pelvic disease at initial staging and no tumor marker elevation at restaging had isolated pelvic metastases. Isolated pelvic recurrence was not statistically different when analyzed by initial stage and treatment. The incidence of isolated pelvic metastases in testicular germ cell tumors at restaging CT is low, but no group of patients was found to be without risk. Therefore, given the small, if any, risk of radiation-induced harm, the decision about whether to include routine pelvic CT in surveillance protocols should be individualized.

  18. Netrin-1 expression is an independent prognostic factor for poor patient survival in brain metastases.

    Directory of Open Access Journals (Sweden)

    Patrick N Harter

    Full Text Available The multifunctional molecule netrin-1 is upregulated in various malignancies and has recently been presented as a major general player in tumorigenesis leading to tumor progression and maintenance in various animal models. However, there is still a lack of clinico-epidemiological data related to netrin-1 expression. Therefore, the aim of our study was to elucidate the association of netrin-1 expression and patient survival in brain metastases since those constitute one of the most limiting factors for patient prognosis. We investigated 104 brain metastases cases for netrin-1 expression using in-situ hybridization and immunohistochemistry with regard to clinical parameters such as patient survival and MRI data. Our data show that netrin-1 is strongly upregulated in most cancer subtypes. Univariate analyses revealed netrin-1 expression as a significant factor associated with poor patient survival in the total cohort of brain metastasis patients and in sub-entities such as non-small cell lung carcinomas. Interestingly, many cancer samples showed a strong nuclear netrin-1 signal which was recently linked to a truncated netrin-1 variant that enhances tumor growth. Nuclear netrin-1 expression was associated with poor patient survival in univariate as well as in multivariate analyses. Our data indicate both total and nuclear netrin-1 expression as prognostic factors in brain metastases patients in contrast to other prognostic markers in oncology such as patient age, number of brain metastases or Ki67 proliferation index. Therefore, nuclear netrin-1 expression constitutes one of the first reported molecular biomarkers for patient survival in brain metastases. Furthermore, netrin-1 may constitute a promising target for future anti-cancer treatment approaches in brain metastases.

    Background To report location and management of atypical metastases from renal cell carcinoma (RCC) in the Instituto Nacional de Ciencias Medicas e Investigacion Salvador Zubiran (INCMNSZ) in Mexico City. Methods Between 1987 to 2009, 545 patients with RCC were retrospectively identified at the INCMNSZ. Patients with unusual metastases confirmed by histopathology were analyzed. Epidemiological, clinical, diagnosis, treatment and outcome data were reviewed. Results Sixty patients developed 98 unusual metastases secondary to RCC. The group was comprised of 35 men (58.3%), with a median age of 60 years at diagnosis. Metachronous unusual metastases with primary renal cancer were observed in 37 individuals (61.7%). Median time from primary RCC diagnosis to the first unusual metastasis was 16.5 months. Median survival from diagnosis of the first unusual metastasis to death was 5.0 months (CI 95%: 2.8-7.2 months). Patients with an initial solitary metastatic lesion in an unusual site (28.3%) had a better survival compared to patients who primarily presented with multiple metastases, 17.0 (CI 95%: 6.1-27.9) Vs 3.0 months (CI 95%: 0.9-5.1), p = 0.001. Unusual metastasis resection (21 patients) improved survival, 25.0 (CI 95%: 5.1-44.9) Vs 3.0 months (CI 95%: 0.8-5.2), p < 0.0001. No survival difference was observed between localization of unsual metastases (p = 0.72). Conclusions In patients with advanced RCC we suggest an individual diagnostic and surgical approach to achieve complete resection with disease-free margins, even in the presence of unusual metastatic sites, multifocality, or history of metastasectomy. These strategy might provide not only palliation for symptoms, but an opportunity for meaningful disease free and overall survival. PMID:29147198

    2009-01-01

    Purpose: The prognosis of hepatocellular carcinoma (HCC) patients with extrahepatic metastases is extremely poor. Helical tomotherapy, an image-guided, intensity-modulated radiotherapy system, can allow for simultaneous and precise targeting of multiple cancerous lesions, while sparing normal tissues. This study evaluated the feasibility and outcome of tomotherapy for advanced HCC with metastases. Patients and Methods: A total of 42 consecutive HCC patients with metastases were treated with tomotherapy using the Hi-Art system. A total of 152 intra- and extrahepatic lesions (3.5 lesions/patient) were treated simultaneously, with a dose of 51.03 Gy (range, 30-57.61) in 10 fractions. Transarterial chemolipiodolization using epirubicin (50 mg) and cisplatin (60 mg) was repeated in patients with intrahepatic HCC (mean size, 9.0 cm) after tomotherapy. Results: An objective response (complete response and partial response) was achieved in 45.2% of patients with intrahepatic tumors, 68.4% of patients with pulmonary lesions, 60.0% of patients with lymph node/adrenal lesions, and 66.7% of patients with soft-tissue metastases. The complete response rate for those with pulmonary and lymph node/adrenal metastases was 26.3% and 5.0%, respectively. The overall survival rate at 1 and 2 years was 50.1% and 14.9%, respectively, with a median survival of 12.3 months. The actuarial in-field tumor control rate for ≤1 year was 79.0%. No cases of Grade 4-5 acute toxicity occurred. Conclusion: The results of this study have shown that helical tomotherapy is safe and feasible without major toxicities for the treatment of advanced HCC and results in excellent tumor control and a potential survival benefit. This approach is expected to be a useful palliative option for selected HCC patients with metastases.

    2016-01-01

    Full Text Available Background: More than half of female patients with breast cancer are diagnosed with a  luminal subtype of the disease; however, specific characteristics of its metastases to the brain have been not well studied, unlike those of HER2 positive and triple negative subtypes. Aim: A  comparative analysis of characteristics of metastatic brain lesions in patients with luminal breast cancer. Materials and methods: The time from surgery for breast cancer to the first recurrence and to metastatic brain lesions (assessed by contrast-enhanced MRI imaging was measured in 41 patients with luminal subtype of breast cancer (median age, 49.5±9.6  years, depending on a  diameter of the primary tumor and numbers of involved axillary lymph nodes. Results: The time interval to occurrence of brain metastases in luminal subtype of breast cancer is not associated with the size of the tumor. If≥4  axillary lymph nodes are involved (N2–3, brain metastases are identified much earlier (p<0.05 than in patients with N0–1 (34.5±23.9 months and 62.7±50 months, respectively. Neither the size nor the involvement of axillary lymph nodes has any impact on the rates of metastatic lesion to the brain during the first recurrence. Conclusion: Brain metastases occur at a much shorter time in those patients of luminal subtype of breast cancer who have metastases in≥4  axillary lymph nodes. Brain metastases develop in 50% of patients with the first recurrence of the luminal subtype of breast cancer.

    Stereotactic ablative body radiotherapy (SABR) is an emerging treatment technique for pulmonary metastases in which conventional Response Evaluation Criteria in Solid Tumours (RECIST) may be inadequate. This study aims to assess the utility of CT perfusion imaging in response assessment of pulmonary metastases after SABR. In this ethics board-approved prospective study, 11 patients underwent a 26-Gy single fraction of SABR to pulmonary metastases. CT perfusion imaging occurred prior to and at 14 and 70 days post-SABR. Blood flow (mL/100 mL/min), blood volume (mL/100 mL), time to peak (seconds) and surface permeability (mL/100 mL/min), perfusion parameters of pulmonary metastases undergoing SABR, were independently assessed by two radiologists. Inter-observer variability was analysed. CT perfusion results were analysed for early response assessment comparing day 14 with baseline scans and for late response by comparing day 70 with baseline scans. The largest diameter of the pulmonary metastases undergoing SABR was recorded. Ten patients completed all three scans and one patient had baseline and early response assessment CT perfusion scans only. There was strong level of inter-observer agreement of CT perfusion interpretation with a median intraclass coefficient of 0.87 (range 0.20-0.98). Changes in all four perfusion parameters and tumour sizes were not statistically significant. CT perfusion imaging of pulmonary metastases is a highly reproducible imaging technique that may provide additional response assessment information above that of conventional RECIST, and it warrants further study in a larger cohort of patients undergoing SABR. © 2015 The Royal Australian and New Zealand College of Radiologists.

  3. MiRNA-21 Expression Decreases from Primary Tumors to Liver Metastases in Colorectal Carcinoma.

    Fabian Feiersinger

    Full Text Available Metastasis is the major cause of death in colorectal cancer patients. Expression of certain miRNAs in the primary tumors has been shown to be associated with progression of colorectal cancer and the initiation of metastasis. In this study, we compared miRNA expression in primary colorectal cancer and corresponding liver metastases in order to get an idea of the oncogenic importance of the miRNAs in established metastases.We analyzed the expression of miRNA-21, miRNA-31 and miRNA-373 in corresponding formalin-fixed paraffin-embedded (FFPE tissue samples of primary colorectal cancer, liver metastasis and healthy tissues of 29 patients by quantitative real-time PCR.All three miRNAs were significantly up-regulated in the primary tumor tissues as compared to healthy colon mucosa of the respective patients (p < 0.01. MiRNA-21 and miRNA-31 were also higher expressed in liver metastases as compared to healthy liver tissues (p < 0.01. No significant difference of expression of miRNA-31 and miRNA-373 was observed between primary tumors and metastases. Of note, miRNA-21 expression was significantly reduced in liver metastases as compared to the primary colorectal tumors (p < 0.01.In the context of previous studies demonstrating increased miRNA-21 expression in metastatic primary tumors, our findings raise the question whether miRNA-21 might be involved in the initiation but not in the perpetuation and growth of metastases.

    BACKGROUND: Axillary nodal status is an important prognostic predictor in patients with breast cancer. This study evaluated the sensitivity and specificity of ultrasound-guided core biopsy (Ax US-CB) at detecting axillary nodal metastases in patients with primary breast cancer, thereby determining how often sentinel lymph node biopsy could be avoided in node positive patients. STUDY DESIGN: Records of patients presenting to a breast unit between January 2007 and June 2010 were reviewed retrospectively. Patients who underwent axillary ultrasonography with or without preoperative core biopsy were identified. Sensitivity, specificity, positive predictive value, and negative predictive value for ultrasonography and percutaneous biopsy were evaluated. RESULTS: Records of 718 patients were reviewed, with 445 fulfilling inclusion criteria. Forty-seven percent (n = 210\\/445) had nodal metastases, with 110 detected by Ax US-CB (sensitivity 52.4%, specificity 100%, positive predictive value 100%, negative predictive value 70.1%). Axillary ultrasonography without biopsy had sensitivity and specificity of 54.3% and 97%, respectively. Lymphovascular invasion was an independent predictor of nodal metastases (sensitivity 60.8%, specificity 80%). Ultrasound-guided core biopsy detected more than half of all nodal metastases, sparing more than one-quarter of all breast cancer patients an unnecessary sentinel lymph node biopsy. CONCLUSIONS: Axillary ultrasonography, when combined with core biopsy, is a valuable component of the management of patients with primary breast cancer. Its ability to definitively identify nodal metastases before surgical intervention can greatly facilitate a patient\\'s preoperative integrated treatment plan. In this regard, we believe our study adds considerably to the increasing data, which indicate the benefit of Ax US-CB in the preoperative detection of nodal metastases.

    Since the introduction of the sentinel node technique for breast cancer in the 1990s patient's morbidity was reduced. Tracer uptake is known to be dependent from lymph node integrity and activity of macrophages. The aim of this study was to assess whether radioactivity of the tracer can predict sentinel lymph node metastases. Furthermore, a potential association with Ki-67 index was examined. Non-invasive prediction of lymph node metastases could lead to a further decrease of morbidity. We retrospectively analyzed patients with primary breast cancer who underwent surgery at the Department of Obstetrics and Gynecology in the University Hospital of Cologne between 2012 and 2013. Injection of radioactive tracer was done a day before surgery in the department of Nuclear Medicine. Clinical data and radioactivity of the sentinel node measured the day before and intraoperatively were abstracted from patient's files. Of 246 patients, 64 patients had at least one, five patients had two and one patient had three positive sentinel lymph nodes. Occurrence of sentinel lymph node metastases was not associated with preoperative tracer activity (p = 0,319), intraoperative tracer activity of first sentinel node (p = 0,086) or with loss of tracer activity until operation (p = 0,909). There was no correlation between preoperative Ki-67 index and occurrence of lymph node metastases (p = 0,403). In our cohort, there was no correlation between radioactivity and sentinel node metastases. Tracer uptake might not only be influenced by lymph node metastases and does not predict metastatic lymph node involvement. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Stereotactic ablative body radiotherapy (SABR) is an emerging treatment technique for pulmonary metastases in which conventional Response Evaluation Criteria in Solid Tumours (RECIST) may be inadequate. This study aims to assess the utility of CT perfusion imaging in response assessment of pulmonary metastases after SABR. In this ethics board-approved prospective study, 11 patients underwent a 26-Gy single fraction of SABR to pulmonary metastases. CT perfusion imaging occurred prior to and at 14 and 70 days post-SABR. Blood flow (mL/100 mL/min), blood volume (mL/100 mL), time to peak (seconds) and surface permeability (mL/100 mL/min), perfusion parameters of pulmonary metastases undergoing SABR, were independently assessed by two radiologists. Inter-observer variability was analysed. CT perfusion results were analysed for early response assessment comparing day 14 with baseline scans and for late response by comparing day 70 with baseline scans. The largest diameter of the pulmonary metastases undergoing SABR was recorded. Ten patients completed all three scans and one patient had baseline and early response assessment CT perfusion scans only. There was strong level of inter-observer agreement of CT perfusion interpretation with a median intraclass coefficient of 0.87 (range 0.20–0.98). Changes in all four perfusion parameters and tumour sizes were not statistically significant. CT perfusion imaging of pulmonary metastases is a highly reproducible imaging technique that may provide additional response assessment information above that of conventional RECIST, and it warrants further study in a larger cohort of patients undergoing SABR.

    The objective of this retrospective study was to evaluate the safety and efficacy of percutaneous microwave ablation (MWA) for treating lung metastases from nasopharyngeal carcinoma (NPC). From December 2012 to November 2014, 17 patients (15 males, and two females, averaged 45.7 years old) with lung metastases from NPC accepted computed tomography (CT)-guided percutaneous MWA. The average number of lung metastases was 1.7 (range: 1-4), and the biggest tumor diameter was 4.2 cm (range: 0.8-4.2 cm). Nineteen nodules located in the right lung and 10 nodules located in the left lung. A total of 29 ablation sites were performed to 29 lung metastases in 22 MWA sessions. Postoperative assessments of complete tumor necrosis rate, safety, local tumor progression, and survival period were carried out. Of the 29 lesions, complete response was achieved for 27 lesions; residual tumor was found in one lesion 3 months postoperatively; and another lesion was found enlarged 3-month postoperatively with obvious enhancement. Four patients had a small amount of postoperative parenchyma bleeding and two patients had a small amount of pneumothorax. Six months after MWA treatment, new metastatic lesions appeared in six patients, five patients had new metastatic lesions inside the lung, and the other patient had metastatic lesions in the thoracic vertebra. The time for the appearance of new pulmonary metastases for the five patients was 4-20 months, averaged 7.2 months. CT-guided MWA is a promising treatment alternative for local tumor control in selected patients with lung metastases from NPC.

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

    Surgery is the treatment of choice in patients with colorectal liver metastases. However, only 10% to 20% of these cases are resectable. The use of neoadjuvant chemotherapy may allow surgery in patients with tumors initially considered unresectable. The aim of this study was to compare the results of liver resection due to colorectal liver metastases in patients with and without neoadjuvant chemotherapy. We studied 105 patients who underwent surgery for liver metastases from colorectal cancer. The patients were divided into two groups according to treatment: surgery in patients with initially resectable tumors (group 1) and neoadjuvant chemotherapy plus surgery (group 2) in patients with initially irresectable tumors, who were considered for surgery after response to chemotherapy. Age, sex, origin of primary tumor, time of presentation, number, maximum size and location of metastases, CEA, resection margin, postoperative morbidity and mortality, length of hospital stay, recurrence rate, survival and disease-free survival were compared between the 2 groups of patients. When group 1 was compared with group 2, statistically significant differences were observed in synchronicity (30.8% vs 77.4%), bilobarity (13.5% vs 58.5%), number and size of metastases (1 vs 3 nodules and 4 cm vs 2 cm), resectability rate (96.1% vs 81.1%), disease-free interval (25 vs 11 months) and long-term survival at 1, 3 and 5 years (93%, 67% and 36% vs 78%, 26% and 12%). However, no statistically significant differences were found in postoperative morbidity and mortality (28.8% and 0% in group 1 and 22.6% and 1.8% in group 2, respectively). Neoadjuvant chemotherapy was not associated with greater postoperative morbidity and mortality after resection of colorectal liver metastases, but long-term survival was lower in the group of patients receiving this treatment modality than in those with tumors initially considered resectable.

    Purpose: Many patients with brain metastases receive whole-brain radiotherapy (WBRT) alone. Using 10 × 3 Gy in 2 weeks is the standard regimen in most centers. Regarding the extraordinarily poor survival prognosis of elderly patients with multiple brain metastases, a shorter WBRT regimen would be preferable. This study compared 10 × 3 Gy with 5 × 4 Gy in elderly patients (≥65 years). Methods and Materials: Data from 455 elderly patients who received WBRT alone for brain metastases were retrospectively analyzed. Survival and local (= intracerebral) control of 293 patients receiving 10 × 3 Gy were compared with 162 patients receiving 5 × 4 Gy. Eight additional potential prognostic factors were investigated including age, gender, Karnofsky performance score (KPS), primary tumor, number of brain metastases, interval from tumor diagnosis to WBRT, extracerebral metastases, and recursive partitioning analysis (RPA) class. Results: The 6-month overall survival rates were 29% after 5 × 4 Gy and 21% after 10 × 3 Gy (p = 0.020). The 6-month local control rates were 12% and 10%, respectively (p = 0.32). On multivariate analysis, improved overall survival was associated with KPS ≥ 70 (p < 0.001), only one to three brain metastases (p = 0.029), no extracerebral metastasis (p = 0.012), and lower RPA class (p < 0.001). Improved local control was associated with KPS ≥ 70 (p < 0.001), breast cancer (p = 0.029), and lower RPA class (p < 0.001). Conclusions: Shorter-course WBRT with 5 × 4 Gy was not inferior to 10 × 3 Gy with respect to overall survival or local control in elderly patients. 5 × 4 Gy appears preferable for the majority of these patients.

    Purpose: The 1-year local control rates after single-fraction stereotactic radiotherapy (SRT) for brain metastases > 3 cm diameter are less than 70%, but with fractionated SRT (FSRT) higher local control rates have been reported. The purpose of this study was to compare our treatment results with SRT and FSRT for large brain metastases. Materials and methods: In two consecutive periods, 41 patients with 46 brain metastases received SRT with 1 fraction of 15 Gy, while 51 patients with 65 brain metastases received FSRT with 3 fractions of 8 Gy. We included patients with brain metastases with a planning target volume of > 13 cm{sup 3} or metastases in the brainstem. Results: The minimum follow-up of patients still alive was 22 months. Comparing 1 fraction of 15 Gy with 3 fractions of 8 Gy, the 1-year rates of freedom from any local progression (54% and 61%, p = 0.93) and pseudo progression (85% and 75%, p = 0.25) were not significantly different. Overall survival rates were also not different. Conclusion: The 1-year local progression and pseudo progression rates after 1 fraction of 15 Gy or 3 fractions of 8 Gy for large brain metastases and metastases in the brainstem are similar. For better local control rates, FSRT schemes with a higher biological equivalent dose may be necessary. (orig.)

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

    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.

    Carcinomas of lung, breast, colon, kidney, and malignant melanomas are the most common malignancies that metastasize to the central nervous system (CNS). Phyllodes tumor is a rare fibroepithelial tumor of the breast, often having unpredictable recurrences, with increasing histological grade and distant metastasis. Malignant forms exist, which may develop distant metastases usually to the lung, pleura, bone, and liver. CNS metastasis of phyllodes tumor is rare and associated with a poor prognosis, with resistance to chemotherapy and radiation. We present a rare case of cerebellar metastasis in recurrent phyllodes tumor breast with subsequent rapid downhill course.

    Full Text Available Because stage 4 lung cancer is associated with dismal 5-year survival rates, new treatment approaches targeting extrapulmonary disease are necessary. Yttrium-90 microsphere radioembolization is an emerging treatment for metastatic hepatic malignancies that results in high tumor response rates and extended patient survival. To date, application of this therapy toward management of lung cancer hepatic metastases has not been extensively described. Herein, we present 2 cases of effective yttrium-90 radioembolization for treatment of lung cancer hepatic metastases, and emphasize the potential coadjuvant value of this procedure in patients with advanced-stage lung cancer and liver-dominant metastatic disease.

    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

    Colorectal cancer (CRC) is a leading cause of cancer-associated deaths with liver metastases developing in 25-30% of those affected. Previous data suggest a survival difference between right- and left-sided liver metastatic CRC, even though left-sided cancer has a higher incidence of liver metastases. The aim of the study was to describe the liver metastatic patterns and survival as a function of the characteristics of the primary tumour and different combinations of metastatic disease. A retrospective population-based study was performed on a cohort of patients diagnosed with CRC in the region of Stockholm, Sweden during 2008. Patients were identified through the Swedish National Quality Registry for Colorectal Cancer Treatment (SCRCR) and additional information on intra- and extra-hepatic metastatic pattern and treatment were retrieved from electronic patient records. Patients were followed for 5 years or until death. Factors influencing overall survival (OS) were investigated by means of Cox regression. OS was compared using Kaplan-Meier estimations and the log-rank test. Liver metastases were diagnosed in 272/1026 (26.5%) patients within five years of diagnosis of the primary. Liver and lung metastases were more often diagnosed in left-sided colon cancer compared to right-sided cancer (28.4% versus 22.1%, p = 0.029 and 19.7% versus 13.2%, p = 0.010, respectively) but the extent of liver metastases were more extensive for right-sided cancer as compared to left-sided (p = 0.001). Liver metastatic left-sided cancer, including rectal cancer, was associated with a 44% decreased mortality risk compared to right-sided cancer (HR = 0.56, 95% CI: 0.39-0.79) with a 5-year OS of 16.6% versus 4.3% (p < 0.001). In liver metastatic CRC, the presence of lung metastases did not significantly influence OS as assessed by multivariate analysis (HR = 1.11, 95% CI: 0.80-1.53). The worse survival in liver metastatic right-sided colon cancer could possibly be

    Several studies have shown that the immunophenotype of distant breast cancer metastases may differ significantly from that of the primary tumor, especially with regard to differences in the level of hormone receptor protein expression, a process known as receptor conversion. This study aimed to compare expression levels of several membrane proteins between primary breast tumors and their corresponding distant metastases in view of their potential applicability for molecular imaging and drug targeting. Expression of Claudin-4, EGFR, CAIX, GLUT-1 and IGF1R was assessed by immunohistochemistry on tissue microarrays composed of 97 paired primary breast tumors and their distant (non-bone) metastases. In both the primary cancers and the metastases, Claudin-4 was most frequently expressed, followed by GLUT-1, CAIX and EGFR.From primary breast cancers to their distant metastases there was positive to negative conversion, e.g. protein expression in the primary tumor with no expression in its paired metastasis, in 6%, 19%, 12%, 38%, and 0% for Claudin-4 (n.s), GLUT-1 (n.s), CAIX (n.s), EGFR (n.s) and IGF1R (n.s) respectively. Negative to positive conversion was seen in 65%, 47%, 43%, 9% and 0% of cases for Claudin-4 (p = 0.049), GLUT-1 (p = 0.024), CAIX (p = 0.002), EGFR (n.s.) and IGF1R (n.s.) respectively. Negative to positive conversion of Claudin-4 in the metastasis was significantly associated with tumor size (p = 0.015), negative to positive conversion of EGFR with negative PR status (p = 0.046) and high MAI (p = 0.047) and GLUT-1 negative to positive conversion with (neo)adjuvant chemotherapy (p = 0.039) and time to metastasis formation (p = 0.034). CAIX and GLUT-1 expression in the primary tumor were significantly associated with high MAI (p = 0.008 and p = 0.038 respectively). Claudin-4 is frequently expressed in primary breast cancers but especially in their metastases and is thereby an attractive membrane bound molecular imaging and drug target. Conversion in

    The aim of this case report and review was to determine the characteristics of retinoblastoma. One case report was introduced along with previous reports on retinoblastoma metastasizing to the mandible. Sixteen cases from 14 reports were included in this study. Including the present case, 11 of 16 patients died within 8 months. Retinoblastoma rarely metastasizes to the mandible. However, metastasis to other organs should be considered, and specialists should be consulted if retinoblastoma metastasis to the mandible is observed. Moreover, it is necessary to follow up patients after multidisciplinary therapy is completed, because subsequent complications of the teeth and jawbones associated with therapy could occur.

Case 2 presents a 60-year-old man with liver metastasis found at autopsy, and, in this case, it is more difficult to find an explanation. This patient had two spontaneous intracerebral bleeding incidents...... and extensive bleeding during acute surgery with tumor removal, which might have induced extracranial seeding. The cases presented might have hematogenous spreading in common as an explanation to extracranial metastases from GBM....

    The efficacy of internal radiotherapy of metastases of differentiated thyroid carcinoma is optimal when the lesions are small or microscopic in size, but decreases rapidly when the metastatic mass exceeds several grams. In this last situation the role of internal radiotherapy should be discussed relative to surgery (when possible) and external radiotherapy. When metastases do not take up iodine-131 (about a third of cases) and are not visualized by conventional imaging techniques, several radiopharmaceutical agents with relative tumor specificity can facilitate their visualization and guide surgical strategy. None of the radiopharmaceutical agents currently under evaluation have demonstrated a clear superiority for this purpose.

    Adenoid cystic carcinoma (ACC) of the breast is a rare malignant salivary-type neoplasm that has a good prognosis and represents less than 1% of all breast cancers. It is a triple negative carcinoma that presents as a painful mass. The mean age at the time of diagnosis is 50-60 years old. The solid variant of this type of tumour with basaloid features and presence of nodal metastases is very rare and considered to have a more aggressive clinical course. We present a case with presence of axillary lymph node metastases that was successfully treated with no evidence of recurrence one year after the diagnosis and review the literature.

    Detection of incidental malignant lesions in the breast has a significant clinical impact not only on healthy individuals but also on patients with known malignant disease. This review describes a spectrum of metastatic breast lesions incidentally detected by FDG PET-CT at staging that may be misinterpreted as second primary malignancy. The common non-mammary malignancies that metastasize to the breast include melanoma, hematopoietic malignancies and epithelial cancers. We present the FDG PET-CT features of incidental non-mammary metastases to the breast that may help distinguish primary breast cancer from metastatic disease and aid in the management of patients with a known malignancy.

    Purpose: Brain metastases in bladder cancer patients are extremely rare. Most patients with multiple lesions receive longer-course whole-brain radiotherapy (WBRT) with 10 x 3 Gy/2 weeks or 20 x 2 Gy/4 weeks. Because its radiosensitivity is relatively low, metastases from bladder cancer may be treated better with hypofractionated radiotherapy. This study compared short-course hypofractionated WBRT (5 x 4 Gy/1 week) to longer-course WBRT. Methods and Materials: Data for 33 patients receiving WBRT alone for multiple brain metastases from transitional cell bladder carcinoma were retrospectively analyzed. Short-course WBRT with 5 x 4 Gy (n = 12 patients) was compared to longer-course WBRT with 10 x 3 Gy/20 x 2 Gy (n = 21 patients) for overall survival (OS) and local (intracerebral) control (LC). Five additional potential prognostic factors were investigated: age, gender, Karnofsky performance score (KPS), number of brain metastases, and extracranial metastases. The Bonferroni correction for multiple tests was used to adjust the p values derived from the multivariate analysis. p values of <0.025 were considered significant. Results: At 6 months, OS was 42% after 5 x 4 Gy and 24% after 10 x 3/20 x 2 Gy (p = 0.31). On univariate analysis, improved OS was associated with less than four brain metastases (p = 0.021) and almost associated with a lack of extracranial metastases (p = 0.057). On multivariate analysis, both factors were not significant. At 6 months, LC was 83% after 5 x 4 Gy and 27% after 10 x 3/20 x 2 Gy (p = 0.035). Improved LC was almost associated with a KPS of ≥70 (p = 0.051). On multivariate analysis, WBRT regimen was almost significant (p = 0.036). KPS showed a trend (p = 0.07). Conclusions: Short-course WBRT with 5 x 4 Gy should be seriously considered for most patients with multiple brain metastases from bladder cancer, as it resulted in improved LC.

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