Our results show that the above described combined treatment is an effective method for the chemotherapy of both Pgp+ and Pgp− human ovarian carcinoma and epidermoid adenocarcinoma tumors growing in mice, and the efficacy of the treatment can be followed by miniPET using 18FDG, 18F-FLT, and 11C-methionine radiotracers. This evidence concerns the gene PGP and ovarian carcinoma.
