Simultaneous breast cancer and DLBCL lymphoma — role of PET/CT examination with 18F-FDG and 18F-FES

Abstract

Breast cancer is the most common cancer in women in the western world.

The estrogen receptor (ER) is expressed in two thirds of newly diagnosed breast cancers, so hormonal treatment is performed only in the receptor positive patients. The most successful ER imaging radiopharmaceutical in PET techniques is 16α-[18F]-flouro-17β-estradiol (¹⁸F-FES).

The diffuse large B cell lymphoma (DLBCL) is one of the most common NHL, however, non-Hodgkin lymphoma constitutes only 4% of all primary cancers in women. The typical staging of disease is done using 18-fluorodeoksyglukose (¹⁸F-FDG) PET/CT.
