RESUMO
Carcinoid tumors are malignancies originating from neuroendocrine cells, most commonly encountered in the gastrointestinal tract, in a rate of 64%, with the majority affecting the ileum. Certain genetic syndromes sometimes include carcinoid tumors in their phenotype. These malignancies may be rather asymptomatic, although occasionally they behave aggressively. They are typically diagnosed due to the effects of a locally advanced disease, or when producing symptoms because of hormone secretion (carcinoid syndrome). A better understanding of their molecular biology and behavior is demanded so that these tumors to be diagnosed precociously and managed effectively.

The main goal of the paper is to clarify anthelminthic treatment as an alternative hydatic cyst therapy, its indications and contraindications. Chemotherapy constitutes a non-invasive treatment and is less limited by the patient's status than surgery or PAIR. Many investigators have employed benzoimidazole carbonates for the management of human hydatid disease. Both, albendazole and mebendazole have, a favourable effect in patients suffering from multiorgan and multicystic disease, in inoperable primary liver or lung echinococcosis, and they can also prevent secondary echinococcosis. Chemotherapy is contraindicated for large cysts that are at risk to rupture and for inactive or calcified cysts. The main adverse events are related to changes in liver enzyme levels. The best efficacy is observed with liver, lung, and peritoneal cysts. Certain various factors influence the therapeutic results of medical treatment. The vast majority of the recurring cysts show good susceptibility to re-treatment.
