About this trial

This project aims to perform complete sequencing of the somatic (tumor) and germline exomes during clinical investigation of cancer patients treated through the Brazilian Unified Health System to generate genomic and phenotypic data for the Brazilian Ministry of Health's National Precision Genomics and Health Program, called Genomas Brasil, as well as to collect data on the population's ancestry.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Women aged ≥ 18 years;

Brazilian nationality;

After review at the Hospital Moinhos de Vento, confirmed histological diagnosis of breast carcinoma with overexpression of HER2 (classified by immunohistochemistry as 3+ or 2+ with positive in-situ hybridization) or triple-negative (estrogen and progesterone receptors <1% and no overexpression of HER2);

Clinical stage II or III for HER2-positive and I, II and III for triple-negative patients - American Joint Committee on Cancer (AJCC) 8th edition;

Disqualifiers

No available paraffin-embedded tumor tissue for genomic analysis;

Inability to collect blood for genomic evaluation.

Trial population

Institutions from each region that serve Public Health System patients and have high complexity oncology care centers will be included in both Arms to provide a sample that represents the heterogeneity of the Brazilian population. Institutions previously evaluated and validated by the Brazilian Ministry of Health will be selected after completing a feasibility questionnaire. It is estimated that 25 to 30 institutions will be included (at least one from each region) in Arm 1. For Arm 2, 10 centers will be selected from among previously approved institutions.

Trial outcomes

Primary outcomes

1

To characterize complete somatic and germline exomes/genomes in a Brazilian population

Mutations in the somatic and germline exomes/genomes of women with HER2-positive and triple-negative breast cancer and of men with metastatic prostate cancer will be described

Time frame
12 months

Secondary outcomes

1

To identify genetic variants related to tumor prognosis

Mutations in the somatic and germline exomes/genomes will be correlated to clinical outcomes

Time frame
12 months
2

To identify genetic variants predictive of response to treatments

Mutations in the somatic and germline exomes/genomes will be correlated to response to treatments

Time frame
12 months
3

Number of patients with mutations in cancer-predisposing genes

Identify mutations in germline exomes/genomes related to hereditary cancer syndromes

Time frame
12 months

Other outcomes

1

To identify the ancestry of patients with breast and prostate cancer

Characterize the genomic ancestry of Brazilian patients with breast and prostate cancer

Time frame
12 months
