Molecular Ovarian Cancer Assessment in LatiNoAmerican PAtients (MOANA)

24. august 2026 oppdatert av: Latin American Cooperative Oncology Group

This is a multicentric observational study conducted at selected sites across Latin America. Eligible participants will be identified through the medical records of participating institutions. The study aims to describe overlap of expression of folate receptor alpha (FRα), HER2 and PD-L1 using immunohistochemistry (IHC) and HRD and BRCA (somatic and germline) by NGS. Additionally, to describe clinical demographic and socioeconomic variables, as well as treatment patterns, pathological characteristics, outcomes, and genetic and molecular testing part of clinical practice.

All data (including patient characteristics, treatment patterns, outcomes and available tests) will be collected once, retrospectively from medical records, ensuring adherence to ethical standards and participant confidentiality. Biomarkers analysis (including FRα, HER2 and PD-L1) will be performed prospectively, a Formalin-Fixed Paraffin-Embedded (FFPE) tumor block will be collected to evaluate and describe the expression of folate receptor alpha (FRα) and HER2, using immunohistochemistry (IHC) with the Roche Ventana kit (FOLR1 and HER2 4B5) and Dako's 22C3 for PD-L1. The study will analyze samples collected between 1st January 2018 to 31 December 2024 (analysis of historically collected samples).

The study comprises a retrospective data collection from medical charts. Participants will continue to receive treatment and clinical evaluations according to what is determined by their medical team, according to the usual standards of treatment and clinical practice of each center. No intervention or prospective follow-up is proposed in this study.

Detaljert beskrivelse

The study combines a retrospective collection of clinical, sociodemographic, pathological, and treatment history data from medical records with a prospective laboratory analysis of archived tumor tissue samples collected between 2018 and 2024.

Biomarker Evaluation & Central Pathology:

Archival formalin-fixed paraffin-embedded (FFPE) tumor tissue blocks or unstained slides will undergo centralized digital pathology review and immunohistochemical (IHC) evaluation to assess expression levels:

  • Folate Receptor Alpha (FRa): Assessed using the Roche Ventana FOLR1 assay.
  • HER2: Evaluated using the Roche Ventana HER2 (4B5) assay.
  • PD-L1: Evaluated using Dako 22C3.
  • Additional exploratory IHC markers (ER, PR, MLH1, MSH2, MSH6, PMS2) will also be evaluated.

Genetic and molecular status for BRCA1/2 mutations and Homologous Recombination Deficiency (HRD) obtained via Next-Generation Sequencing (NGS) will be extracted retrospectively from medical records as available in routine clinical practice.

All clinical and historical data will be abstracted once retrospectively from participant charts and recorded electronically using a validated REDCap Electronic Data Capture (EDC) system. The study design involves no prospective clinical follow-up or therapeutic interventions; all participants continue standard-of-care treatment as dictated by their treating physicians.

An interim statistical analysis is planned after 50% of the target sample in Brazil has completed baseline assessments, followed by a final analysis upon full study completion.
