A series of PET/CT scans (Maximum Intensity Projections) in the first patient showing: (A) signs of peritoneal carcinomatosis in the subdiaphragmatic space infiltrating the large omentum and associated with ascites, in addition to supradiaphragmatic laterocervical and mediastinal lymphadenopathies, (B) persisting multiple peritoneal implant lesions at the time of treatment initiation, (C)  a significant improvement of the previously described peritoneal lesions with an overall regression of their metabolic activity.

Positron emission tomography/computed tomography (PET/CT) revealed pleuropericardial effusion with multiple mediastinal, internal mammary, and right costo-diaphragmatic angle adenopathies as well as signs of peritoneal carcinomatosis infiltrating the large omentum and associated with ascites ( Figure 1A ). A PET/CT examination at baseline showed progression of multiple peritoneal implant lesions and an overall metabolic progression of a diffuse pleural affection on the right side ( Figure 1B ). Restaging PET/CT examinations performed at 3, 6, and 9 months of treatment initiation showed an overall metabolic regression of the previously described pleural and peritoneal lesions ( Figure 1C ).
