**PROFILES OF INTRATUMORAL MICROBIOTA IN NEUROENDOCRINE NEOPLASMS AND SOFT TISSUE SARCOMAS: NEW PERSPECTIVES FOR DIAGNOSIS, PROGNOSIS AND PREDICTION OF TREATMENT EFFICACY IN RARE TUMORS

Intratumoral microbiota, a component of the tumor microenvironment, is gaining attention for its role in cancer development, progression, and treatment response, largely through its interactions with the host immune system. These interactions may contribute to increased mutational rates and carcinogenesis-related inflammation and mechanisms. Among microorganisms in tumor tissues, bacteria have been notably studied due to their ability to establish symbiotic relationships with the host. Early comprehensive studies have shown that different types of tumors harbor distinct bacterial communities.

Specifically in rare cancers like Neuroendocrine Neoplasms (NEN) and Soft Tissue Sarcoma (STS), which exhibit diverse biological and clinical traits, there is limited but growing research on their particular microbiomes. Preliminary studies in STS have utilized techniques like fluorescence in situ hybridization and bacterial 16S rRNA gene sequencing, revealing distinct bacterial communities within various sarcoma types compared to adjacent healthy tissues. Furthermore, culturomic approaches have allowed for the isolation of live bacteria from sarcoma tissues, which have shown resistance to doxorubicin.

The project aims to:

- Broaden the study of intratumoral microbiota in STS and NEN across different body sites.

- Investigate bacterial mechanisms behind chemotherapy resistance using advanced techniques like mass spectrometry and functional genomics.

- Evaluate the clinical relevance of bacterial activity through in vivo studies and retrospective analyses of patient responses to chemotherapy and immunotherapy.

- Explore potential interventions to counteract bacterial drug degradation to enhance treatment outcomes.

This project will be performed under the guidance of Prof. Silvia Uccella (Silvia Uccella - Hunimed) and Prof. Salvatore Piscuoglio (Salvatore Piscuoglio - Hunimed) in the Precision Medicine research group and will closely cooperate with the Prof. Maria Rescigno (Maria Rescigno - Hunimed) research group

- Microbiota Profiling and Analysis

- Perform fluorescence in situ hybridization (FISH) analysis and gene sequencing to identify and profile intratumor microbiota in histopathological samples.

- Conduct culturomic experiments to isolate and identify live bacteria from tumor tissues

- Assess the ability of bacteria isolated from tumor tissues to degrade chemotherapeutic drugs using mass spectrometry and functional genomic approaches.

- Conduct in vitro and in vivo experiments to understand the mechanisms used by bacteria to resist chemotherapy.
