The CNE compared with the infiltrating ductal and lobular carcinoma are statistically different in relation to the expression of the receptor of c-erb-B2, p53, progesterone, for the lymph node state at diagnosis and the risk of reappearance of breast tumour. Our study confirms the choice to consider the neuroendocrine carcinoma of the breast as a separate histological group and seems to suggest a less aggressiveness of this type of tumour.
There are no significant series of patients in worldwide literature to develop standard protocols. Pregnant women must be followed by a multidisciplinary team.
Pregnancy-related breast cancer (PBC) is one of the most common malignancies during pregnancy (approx. one in 3,000 pregnancies); up to 3% of breast cancers are diagnosed in pregnancy. As maternal age at the time of pregnancy continues to increase as the incidence of breast cancer, the incidence of PBC is expected to increase. A review of the literature was performed in order to identify optimal treatment strategies. Most of the data surrounding the diagnosis and treatment PBC is small cohort studies, and there are no randomized controlled trials. Diagnostic delays are common. Preoperative histologic confirmation is required. Conservative surgery can be proposed at the end of second and third trimester, and radiotherapy is delayed after childbirth. The safety of sentinel lymph node biopsy has yet to be confirmed, and the axillary dissection is the traditional treatment of choice. The chemotherapeutic agents utilized are the same as those used in non-pregnant patients, but they should not be administered in the first trimester. Radiotherapy and endocrine therapy are recommended to be avoided during pregnancy. The treatment of PBC is multidisciplinary and necessitates active communication among the patient, obstetrician, medical, surgical, and radiation oncologists. Diagnosis is often delayed because of physiologic changes of the breast; obstetricians should perform a thorough breast examination at the first prenatal visit and maintain a high index of suspicion for cancer. Other therapies may need to be considered, although their usage now is not currently recommended owing to the paucity of safety data.
Three-dimensional constructive interference in steady state (3D CISS) is a steady-state gradient-echo sequence in magnetic resonance imaging (MRI) that has been used in an increasing number of applications in the study of brain disease in recent years. Owing to the very high spatial resolution, the strong hyperintensity of the cerebrospinal fluid signal and the high contrast-to-noise ratio, 3D CISS can be employed in a wide range of scenarios, ranging from the traditional study of cranial nerves, the ventricular system, the subarachnoid cisterns and related pathology to more recently discussed applications, such as the fundamental role it can assume in the setting of acute ischemic stroke, vascular malformations, infections and several brain tumors. In this review, after briefly summarizing its fundamental physical principles, we examine in detail the various applications of 3D CISS in brain imaging, providing numerous representative cases, so as to help radiologists improve its use in imaging protocols in daily clinical practice.
Objectives: To discuss the non-surgical strategies for the management of cervical lymphangiomas in children, with particular attention to sclerotherapy.
Methods: A literature review of the last fifteen years about sclerotherapy of cervical lymphangiomas in children was performed and the main sclerosing agents were reported, highlighting the nature, the mechanism of action and the rates of success, recurrences and complications related to each and every substance; furthermore, the several steps of the procedure are illustrated. Alternative approaches are also mentioned.
Results: 47 articles were collected, mostly dealing with sclerotherapy with OK-432, bleomycin/pingyangmycin and doxycycline; other potential substances include, above all, sodium tetradecyl-sulphate and ethanol. Laser therapy and radio-frequency ablation are valid options in case of mucosal micro-cystic lesions; oral medications (e.g. Sirolimus) and the newest target-therapies are added to local treatments in some Series.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
