Treatment
For symptomatic relief of carcinoid syndrome:
- octreotide (a somatostatin analogue which decreases the secretion of serotonin by the tumor and, secondarily, decreases the breakdown product of serotonin (5-HIAA))
- peptide receptor radionuclide therapy (PRRT) with lutetium-177, yttrium-90 or indium-111 labelled to octreotate is highly effective
- methysergide maleate (antiserotonin agent but not used because of serious side effect of retroperitoneal fibrosis)
- cyproheptadine (an antihistamine drug with antiserotonergic effects)
Alternative treatment for qualifying candidates:
- Surgical resection of tumor and chemotherapy (5-FU and doxorubicin)
- Endovascular, Chemoembolization, targeted chemotherapy directly delivered to the liver through special catheters mixed with embolic beads (particles that block blood vessels). For patients with liver metastases.

Famous quotes containing the word treatment:
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
“I am glad you agree with me as to the treatment of the mining riots. We shall crush out the lawbreakers if the courts and juries do not fail.”
—Rutherford Birchard Hayes (1822–1893)
