NEUROENDOCRINE TUMORS

• Neuroendocrine Tumors are ill-understood, enigmatic malignancies

• An increased clinical and pathological focus as well as the advent of biochemical and immunohistochemical diagnostic technology has led to a greater awareness of the disease

MEN I • NETs may occur as part of multiple endocrine

neoplasia type 1 (MEN1), • An autosomal dominant disorder associated

with the gene locus MEN1 located on 11q13. • Its protein product (menin) is involved in

transcriptional regulation and genome stability.

CLINICAL PICTURES

• Primary GEP-NETs can be:– Asymptomatic – May present with obstructive symptoms (pain, nausea,

and vomiting)– The syndromes are typically seen in patients with

secretory tumours.

NEUROENDOCRINE TUMORSTREATMENT

The aim of treatment should be curative where possible but is palliative in the majority of cases.

These patients often maintain a good quality of life for a long period despite having metastases.

Although the rate of growth and malignancy are variable, the aim should always be to maintain a good quality of life for as long as possible.

NEUROENDOCRINE TUMORS

SURGERYThis is the only curative treatment for NETs.

Conduct of surgery with intent to cure is dependent on the method of presentation and stage of disease.

TERAPIA ENDOSCOPICA

• Tumori neuroendocrini ben differenziati• Basso indice proliferativo• Dimensioni < 1 cm• Localizzati nella mucosa e/o nella sottomucosa

GI a livello di tutte le sedi raggiungibili da un endoscopio e quindi esofago, stomaco, duodeno, colonretto

• Intestino tenue
