Long-term experience supports efficacy and safety of PRRT for treating neuroendocrine tumours

smiling woman_quality of life_oncology news australiaMore than ten years of published clinical data and personal experience using peptide receptor radionuclide therapy of neuroendocrine tumours supports the effectiveness of this novel treatment approach and the ability to minimise and manage potential toxic side effects.

A comprehensive review of somatostatin analogue PRRT is published in Cancer Biotherapy and Radiopharmaceuticals.

In the article “Myelotoxicity of Peptide Receptor Radionuclide Therapy of Neuroendocrine Tumours: A Decade of Experience,” Murali Kesavan and J. Harvey Turner from The University of Western Australia, state that PRRT has revolutionised the management of patients with neuroendocrine tumours, improving tumour response rates and patients’ progression-free survival.

However, the associated toxicity to blood cells – with the potential to cause thrombocytopenia and neutropenia and, in the long term, myelodysplastic syndrome and acute leukaemia – remains a risk and has limited the use of PRRT.

The researchers suggest that PRRT should more readily be considered a first-line agent in appropriate patients.

“This is an important discussion of the efficacy and toxicity issues relating to the use of PRRT, as the therapy becomes more widely available for the treatment of gastroenteropancreatic tumours with radiolabeled somatostatin analogs,” says Co-Editor-in-Chief Donald J. Buchsbaum, PhD, Department of Radiation Oncology, Division of Radiation Biology, University of Alabama at Birmingham.
