Identification of Genetic, Phenotypic, Clinical, Biological and Histological Factors Differentiating Patients With Ovarian Cancer Who Are Refractory to Platinum-based Therapy From Patients Defined as Long-term Responders to Platinum-based Therapy (ORTRAI)

Centre Jean Perrin

Status: Not yet enrolling

Conditions: Ovarian Cancer

Treatments: Genetic: molecular analysis

Study type: Interventional

Funder types: Other

Identifiers

NCT07361471

Details and patient eligibility

About

After having constituted the ORTRAI cohort using the CONSORE database at the Jean PERRIN Center, the objective is to characterize the patients both clinically and biologically, histologically and genomically.

The clinical and biological characterizations will allow us to confirm that our cohort is comparable with data from the literature.

The complement of immunohistochemical and molecular analyses will provide more details on the differences between long-term patients responding to treatment and refractory patients.

Enrollment: 55 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

  • Group of long-term responders: patients who have not progressed 5 years after the end of first-line platinum salt treatment
