RESUMO
Neuroendocrine Tumors (NETs) encompass a wide variety of tumors arising from neuroendocrine cells, which produce bioactive substances. The incidence of NETs increased significantly lately, becoming one of the most common tumors of the digestive tract. Their clinical presentation is as diverse as their capacity for hormone production. Carcinoid syndrome is the most common hormonal syndrome produced by NETs and is characterized by diarrhea, flushing and cardiac valvular lesions. New research brought multiple changes in the classification of these neoplasms and a new understanding about their diagnosis and treatment, promoting a multidisciplinary approach. Somatostatin analogues, radiation, biological, and cytotoxic drugs have improved the prognosis of these patients, which entails a great challenge for healthcare providers.

Medication-related osteonecrosis of the jaw is a disease where there is necrotic bone exposed or that can be explored by means of a fistula in the maxillofacial region. It has been associated with the use Biphosphonates and denosumab for osteoporosis. Although its etiology is unclear, it may be related to a decrease in bone turnover produced by these drugs, rendering the bone more prone to generate cell necrosis during invasive dental procedures, especially in the posterior region of the jaw. There is no consensus about the prevention and treatment of this condition. The aim of this paper is to present a review of the literature with the main characteristics of osteonecrosis of the jaws associated with drugs, together with a proposal for prevention and treatment for these patients.

Recently, we have witnessed major improvements in cancer treatment. Early diagnosis and development of new therapies have reduced cancer-related mortality. However, these new therapies, along with greater patient survival, are associated with an increase in untoward effects, particularly in the cardiovascular system. Although cardiotoxicity induced by oncologic treatments affects predominantly the myocardium, it can also involve other structures of the cardiovascular system, becoming one of the main causes of morbidity and mortality in those who survive cancer. The main objective of cardio-oncology is to achieve the maximum benefits of oncologic treatments while minimizing their deleterious cardiovascular effects. It harbors the stratification of patients at risk of cardiotoxicity, the implementation of diagnostic tools (imaging techniques and biomarkers) for early diagnosis, preventive strategies and early treatment options for the complications. Herein, we discuss the basic knowledge for the implementation of cardio-oncology units and their role in the management of cancer patients, the diagnostic tools available to detect cardiotoxicity and the present therapeutic options.
