INCA names her, with João Paulo Viola, as coordinator of the Atlas Tumoral da População Brasileira (ATPBR), approved in 2023 with R$8.72 million over three years under the federal Genomas Brasil programme, and she is first author of the paper describing it in The Lancet Regional Health - Americas (2026). Her group's other recent work includes a microRNA-based prognostic model for high-grade serous ovarian cancer in the same journal (2026, last author) and a contribution to a Latin American single-cell genomics perspective in Cell (2025).","asOf":"2026-11-03","links":[{"label":"PubMed author search","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Boroni%20M%5Bau%5D%20INCA"},{"label":"INCA: INCA leads project that drives precision oncology in Brazil (13 March 2026)","url":"https://www.gov.br/inca/pt-br/assuntos/noticias/2026/inca-lidera-projeto-que-impulsiona-oncologia-de-precisao-no-brasil"}],"tags":["computational-biology","genomics"],"related":[],"cancers":["ovarian"],"sections":[],"technologies":["cgp"],"targets":[],"drugs":[],"companies":[],"institutions":["inca-brazil"],"pathways":[],"terms":["ngs"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":["paper-boroni-atpbr-lancet-rha-2026"],"journals":[],"dependsOn":[],"notes":[],"provenance":{"editedBy":"OnCo country deep dive, Brazil (wave 2)","editedOn":"2026-11-03"},"role":"Researcher, Laboratory of Bioinformatics and Computational Biology, Instituto Nacional de Câncer (INCA), Rio de Janeiro","institutionId":"inca-brazil","specialisms":["Cancer bioinformatics","Cancer genomics","Single-cell and multi-omics analysis","Ovarian cancer"],"profiles":[{"label":"PubMed author search","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Boroni%20M%5Bau%5D%20INCA"},{"label":"INCA: INCA leads project that drives precision oncology in Brazil (13 March 2026)","url":"https://www.gov.br/inca/pt-br/assuntos/noticias/2026/inca-lidera-projeto-que-impulsiona-oncologia-de-precisao-no-brasil"}],"papers":[{"title":"The Brazilian Population Tumor Atlas Project: addressing representation in cancer genomics in Brazil","journal":"The Lancet Regional Health - Americas","year":2026,"doi":"10.1016/j.lana.2026.101397"},{"title":"Development and validation of a miRNA-based prognostic model for high-grade serous ovarian cancer: a retrospective cohort study","journal":"The Lancet Regional Health - Americas","year":2026,"doi":"10.1016/j.lana.2026.101527"},{"title":"Exploring Latin America one cell at a time","journal":"Cell","year":2025,"doi":"10.1016/j.cell.2025.09.013","note":"One of 57 authors."}]},"route":"/people/mariana-boroni/","neighbours":{"cancer":[{"id":"ovarian","kind":"cancer","name":"Ovarian cancer","route":"/cancers/ovarian/"}],"technology":[{"id":"cgp","kind":"technology","name":"Comprehensive genomic profiling","route":"/technologies/cgp/"}],"institution":[{"id":"inca-brazil","kind":"institution","name":"Instituto Nacional de Câncer (INCA)","route":"/institutions/inca-brazil/"}],"term":[{"id":"ngs","kind":"term","name":"Next-generation sequencing (NGS)","route":"/terms/ngs/"}],"paper":[{"id":"paper-boroni-atpbr-lancet-rha-2026","kind":"paper","name":"The Brazilian Population Tumor Atlas Project: addressing representation in cancer genomics in Brazil","route":"/key-papers/paper-boroni-atpbr-lancet-rha-2026/"}]}}
