Details and patient eligibility

About

Clinicopathological data were collected from ovarian cancer patients treated with PARP inhibitors, with follow-up imaging conducted before and after treatment. The efficacy was evaluated according to RECIST criteria, comparing the correlation between different HRD statuses and the efficacy of PARP inhibitors in ovarian cancer.

Enrollment: 250 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients diagnosed with ovarian cancer (any histological type) and possessing complete pathological hematoxylin and eosin (HE) stained slides and paraffin-embedded tissue blocks.
• Patients must be 18 years of age or older.
• Patients should not have concurrent multiple primary cancers.
• Patients must undergo an MRI or CT scan prior to starting treatment.
• According to RECIST (Response Evaluation Criteria In Solid Tumors) criteria, patients must have at least one measurable lesion.
• Participants must provide informed consent, voluntarily cooperate with clinical follow-up, and sign an informed consent form.

Exclusion criteria

• Patients who do not have accessible tumor tissue required for Homologous Recombination Deficiency (HRD) testing.
• Patients whose clinical records are incomplete, making it impossible to effectively compare treatment efficacy.
• Patients who are lost to follow-up and for whom subsequent treatment outcomes cannot be tracked.

Trial design

250 participants in 2 patient groups

effective group

Description:

The tumor size of each diameter of the tumor before and after treatment was measured on magnetic resonance imaging or CT. According to Recist 1.1 criteria, patients who were evaluated as complete remission, partial remission and stable disease were included in the effective group. Patients assessed as having progressive disease were included in the treatment-refractory group.

Treatment:

Genetic: homologous recombination deficiency

Description:

The tumor size of each diameter of the tumor before and after treatment was measured on magnetic resonance imaging or CT. According to Recist 1.1 criteria. Patients assessed as having progressive disease were included in the ineffective group.

Treatment:
