Despite impressive treatment advances, few options for refractory or relapsed Hodgkin Lymphoma (HL) are available and there is a need for new compounds development. A number of promising agents with multiple mechanisms of action are under investigation. Microenvironment and neoangiogenesis are acquiring a rising relevance in the pathophysiology and progression of HL. Everolimus (RAD001) is an oral antineoplastic agent derived from rapamycin, a macrocyclic lactone antibiotic, targeting the mammalian target of rapamycin (mTOR). Although the importance of mTOR signaling in the deregulated cell growth of human neoplastic cells has been recognized, this pathway is also emerging as a key regulator of the tumor response to hypoxia, as well as endothelial and stromal cells function, thereby regulating neoangiogenesis. Furthermore, mTOR plays an important role in anticancer drug resistance. The actions of everolimus within the mTOR pathway in HL result in decreased protein synthesis and cell cycle arrest, as well as in decreased angiogenesis. Everolimus has shown preliminary evidence of efficacy as a single-agent in heavily pretreated relapsed/refractory HL, with an overall fair safety profile. The purpose of this review is to discuss the employment of everolimus as an antiproliferative and antiangiogenic agent in HL and to report the critical role of the mTOR pathway and angiogenesis in this malignancy.

Antiresorptive agent-related osteonecrosis of the jaw results in appreciable morbidity in affected patients. Nowadays many physicians prescribe an antiangiogenic agent for the management of malignant metastases. Everolimus is a serine-threonine kinase that acts as an inhibitor of mammalian target of rapamycin, which results in reduced growth of cells, angiogenesis, and survival of cells. We report the first case to our knowledge of osteonecrosis of the jaw that seemed to result from the additive effect of everolimus.

Over the past few years, knowledge regarding the molecular pathology of sporadic pancreatic neuroendocrine tumors (PNETs) has increased substantially, and a number of targeted agents have been tested in clinical trials in this tumor type. For some of these agents there is a strong biological rationale. Among them, the mammalian target of rapamycin inhibitor Everolimus and the antiangiogenic agent Sunitinib have both been approved for the treatment of PNETs. However, there is lack of knowledge regarding biomarkers able to predict their efficacy, and mechanisms of resistance. Other angiogenesis inhibitors, such as Pazopanib, inhibitors of Src, Hedgehog or of PI3K might all be useful in association or sequence with approved agents. On the other hand, the clinical significance, and potential for treatment of the most common mutations occurring in sporadic PNETs, in the MEN-1 gene and in ATRX and DAXX, remains uncertain. The present paper reviews the main molecular changes occurring in PNETs and how they might be linked with treatment options.

Primary intestinal lymphangiectasia (PIL), also known as Waldmann's disease, is an exudative enteropathy resulting from morphologic abnormalities in the intestinal lymphatics. In this article, we describe a 12-year-old boy with PIL that led to protein-losing enteropathy characterized by diarrhea, hypoalbuminemia associated with edema (serum albumin level: 1.0 g/dL), and hypogammaglobulinemia (serum IgG level: 144 mg/dL). Severe hypoalbuminemia, electrolyte abnormalities, and tetany persisted despite a low-fat diet and propranolol. Everolimus (1.6 mg/m(2)/day) was added to his treatment as an antiangiogenic agent. With everolimus treatment, the patient's diarrhea resolved and replacement therapy for hypoproteinemia was less frequent. Hematologic and scintigraphy findings also improved (serum albumin level: 2.5 g/dL). There were no adverse reactions during the 12-month follow-up. To the best of our knowledge, this is the first report of everolimus use in a patient with PIL.
