Summary
Brief summary (as posted)
Development of tools to predict patients chemo-sensitivity and identification of corresponding biomarkers is an urgent challenge for BC patients lacking targeted therapies, such as TNBC, or for patients experiencing relapse after adjuvant chemotherapy or targeted therapies. The refinement of 3D-cultivation techniques, experienced in the last decade, has allowed cultivation of patients-derived cancer cells in organotypic structures, named patient-derived organoids (PDO), which preserve histologic, genomic and transcriptomic features of primary tumors. PDO allow propagation, pharmacological treatment and genetic manipulation of patients-derived cancer cells in a close to physiology setting, thus representing a promising tool in the development of personalized therapies

[]Primary outcomes (2)
- measure
- evaluate the histological and molecular conformity (yes/no) between PDO and matched primary and/or recurrent BC sample, in order to develop a live biobank of ER/PR+, HER2+ and TNBC PDO.
- timeFrame
- 36 months
- description
- Part of each surgical specimen will be used to obtain PDOs according to established procedures, part will be fixed and paraffin embedded for histological analysis and part will be flash-frozen for DNA, RNA and protein analyses. At first passages, organoids will be characterized for histologic and cytologic features. PDOs that faithfully recapitulate features of the matched primary tumor will be analysed for genomic features and splicing-sensitive transcriptomic signatures by next generation sequencing (NGS). Dichotomic variable: Yes (conform)/No (not conform)
- measure
- evaluate the sensitivity of ER/PR+, HER2+ and TNBC PDO to novel therapeutic agents in clinical trials for BC or other cancer types
- timeFrame
- 42 months
- description
- PDO will be tested for their susceptibility to the therapeutic agents administered to the corresponding patients and/or to novel therapeutic agents in clinical trials for BC or other cancer types by performing cell viability assays and clonogenic potential assay before and after treatments. Sensitivity to the tested drugs will be evaluated on the basis of the known maximal plasma concentration of the drug (Cmax): sensitive if survival is \<50% at Cmax dose; resistant if survival is \>50% at Cmax dose. Dichotomic variable: Yes (sensitive)/No (resistant)
