We are pleased to inform you that recently an article summarizing the final results of the CEEGOG ox-01/HE4-FU-OVCA study has been published. The CEEGOG ox-01/HE4-FU-OVCA study was the first CEEGOG study to be proposed and approved, focusing on the role of the HE4 marker in the follow-up of advanced ovarian, fallopian tube, and primary peritoneal cancer. The article was published in the Cancers journal, and for your reference, is to be found in the CEEGOG Members´ shared area. Once again, we sincerely thank all participating sites for their valuable cooperation in the CEEGOG ox-01 study. It was a great pleasure for us to work with each of you!
