Normal prostate cells and prostate cancer cells produce prostate-specific antigen (PSA): thus, it is frequently increased in non-malignant conditions such as prostatitis and benign prostatic hyperplasia. Indeed, PSA is an excellent biomarker to monitor disease progression. The low diagnostic specificity of PSA leads to many false-positive and a large number of biopsies. These well-recognized limitations of PSA suggest that new prostate cancer biomarkers could play a useful role in reducing the number of unnecessary biopsies. 相似文献

Nuclear medicine could significantly contribute to management of patients with prostate carcinoma. Apart from bone scintigraphy, and success of sentinel lymph node procedure, from a diagnosis point of view 18F-fluorocholine, which is now disposable, will certainly allow better staging accuracy, better efficiency of recurrences detection, and better treatments evaluation. Regarding to treatments, several radiopharmaceuticals demonstrated their efficiency as palliative treatment of painful bone metastasis, and maybe in the near future will contribute to curative treatment when associated to chemotherapy. 相似文献

Most of patient suffering from a prostate cancer will develop a castration resistance. In this common and clinically challenging situation, chemotherapy was not considered very useful until mid 2000s. Docetaxel is now recognized as a standard of care, improving overall survival and quality of life. However, new drugs are needed. Two compounds (cabazitaxel and abiraterone) are now underway to official registration and an autologous vaccin strategy (Sipuleucel) demonstrated a benefit in survival. Based on a greater knowledge of biology, many other agents are currently under development, such as new specific peripheral anti-androgens, anti-angiogenic therapies, or proteasome inhibitors. All these new drugs are promising and may provide more efficient therapies against this incurable disease in the near future. 相似文献

For the past decade, PET and PET/CT have been widely studied for myocardial perfusion imaging. Several studies demonstrated the incremental value of PET for the diagnostic and prognostic assessment of patients with coronary artery disease. Moreover, PET allows for non-invasively quantifying myocardial blood flow and myocardial flow reserve, that both are recognized as surrogate marker of cardiac event free survival. By enabling the exploration of epicardial disease and the microvasculature, PET constitutes a unique tool to study pathophysiogical mechanisms leading to atherosclerosis genesis. The recent emergence of high-tech hybrid machines may even provide further incremental information about coronary function and morphology. By taking the best of each modality, a better assessment of patients with coronary artery disease is expected. 相似文献

As part of an overall review on the role of PSA and other emerging biomarkers in the detection, diagnosis and treatment of prostate cancer, we present here a part of a review of the literature made by the working group Biologie de la Prostate (AFU, CNBH, SFBC, SFMN) on the use of PSA and other biomarkers in the early detection of prostate cancer with an assessment of the level of evidence. 相似文献

Myocardial 123-I-metaiodobenzylguanidine (MIBG) imaging enables the assessment of postganglionic sympathetic cardiac innervation. Recently myocardial 123-I-MIBG scintigraphy has been found to be useful to distinguishing Parkinsońs disease (PD) from other akinetic rigid syndromes. The absence of published guidelines for cardiac 123-I-MIBG imaging makes standardization of procedures among individual users of this technique even more important. Cardiac MIBG study showed markedly decreased uptake in PD, dementia with Lewy bodies (DLB) and pure autonomic failure, which is a common feature of Lewy body disease. The cardiac MIBG uptake is severely impaired even in the early disease stage. Atypical parkinsonian syndromes, including Multiple System Atrophy, Progressive Supranuclear Palsy, and other, show modest reduction of cardiac MIBG uptake. The MIBG study can be used for differentiating patients with extrapyramidal signs and dementia, and might provide useful diagnostic information to discriminate DLB and Alzheime?s disease. 相似文献

The attention is turned here to one kind of tools, characterized by a special morphology: the grooved hammer-stones. They are known in Europe and all over the world in various cultures, as Neolithic or Bronze Age remains and generally linked to extraction or mining activity; but, the discovery of several of these tools in western France, within pre-roman archaeological contexts, especially in sites devoted to marine salt production, leads us to a discussion on dating and the function of such tools, and feeds a more general reflexion about the existence of a specialised lithic set of tools during the Iron Age. 相似文献
