Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

DOTABREAST: Evaluation of Somatostatin Receptor Expression in PET 68Ga-DOTATOC in Patients Followed for Metastatic Breast Cancer

This is a prospective, monocentric, non-controlled, non-randomized, open-label, interventional study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In women, breast cancer is the 1st largest cancer and accounted for 31% of new cancer cases in women in 2017. With 11,913 deaths in 2015, breast cancer is the 1st largest cancer death in women (19%) and the 3rd largest cancer death (men and women included) after lung and colorectal cancer. At initial diagnosis at any stage, approximately 31% of patients have regional lymph node involvement and 5 to 10% present metastatic involvement from the outset. Progression to a metastatic form occurs in about 20% of cases. The risk of metastatic evolution is variable depending on the histological subtype and is a major prognostic event directly impacting overall survival. DOTATOC-68Ga PET scans allows in vivo evaluation of SST2 somatostatin receptor expression. Its use is widely validated in clinical practice for the assessment of extension of neuroendocrine tumors. It is also being used to evaluate the feasibility of SST2-targeted internal radiotherapy therapy with Lutathera (177Lu-Oxodotreotide) in patients with metastatic small intestine neuroendocrine tumours.
