Rare Cancer Responds Unusually Well to New Treatment

“Vienna, Austria: Patients with advanced gastrointestinal neuroendocrine tumours (NETs) have limited treatment options and there are few oncologists who are specialised in this relatively rare disease. But now results from a multi-centre randomised international trial of an innovative treatment show a marked improvement in the length of time patients with mid-gut NETs live without the disease getting worse (progression-free survival, or PFS), researchers will report to the 2015 European Cancer Congress today.

“Professor Philippe Ruszniewski, MD, Head of the Department of Gastroenterology-Pancreatology, Beaujon Hospital, Clichy, France, who is also a Professor at Paris Diderot University, will tell the Congress that results of the NETTER-1 phase III trial of 177Lu-DOTATATE (Lutathera) show a PFS that has never been shown before in this type of cancer. “Because these patients have a real unmet medical need, this is particularly pleasing for us,” he says.

“Lutathera is a member of the family of novel treatments called Peptide Receptor Radionuclide Therapy (PRRTs) which involve targeting tumours with radiolabelled somatostatin analogue (SSA) peptides. The technique belongs to the larger family of molecular nuclear medicine, where trace amounts of active substances, or radiopharmaceuticals, are used to create images and to treat various diseases including cancer. SSAs are widely used in gastrointestinal NETs cancer to reduce symptoms such as diarrhoea.”
