Prognosis of triple-negative breast cancer associated with pregnancy: A propensity score-matched analysis from the French CALG (Cancer Associé à la Grossesse) network.

Introduction: Triple-negative (TN) breast cancer represents one third of pregnancy-associated breast cancers (PABC). The aims of the current study were to describe oncological and obstetrical outcomes of patients with TN-PABC and to compare their prognosis with TN-non-PABC patients using a propensity score.

Materials And Methods: Between January 2005 and December 2020, data of patients with histologically proven TN-PABC were collected and compared with data of TN-non-PABC patients under the age of 46 years diagnosed during the same period using a propensity score (PS).

Feasibility, Safety and Impact of (18F)-FDG PET/CT in patients with pregnancy-associated cancer: experience of the French CALG (Cancer Associé à La Grossesse) network.

Background: The incidence of pregnancy-associated cancers has been increasing for decades. (18F)-FDG Positron Emission Tomography (PET)/Computed Tomography (CT) imaging has become a golden standard in the staging of many malignant diseases. The aims of the current study were to evaluate the feasibility, safety and impact of (18F)-FDG PET/CT performed during pregnancy.
