Immunological Phenotype of Desmoid-fibromatosis-affected Patients.

This observational study aims to characterize the molecular, phenotypic, and functional inflammatory and immunological profile of patients with sporadic desmoid-type fibromatosis undergoing either active surveillance or systemic therapy. The study includes analysis of the tumor immune microenvironment (TIME), circulating immune and inflammatory molecules, immune cell subsets, and circulating tumor DNA (ctDNA). The goal is to identify biomarkers associated with spontaneous or treatment-induced tumor regression and to evaluate potential correlations with specific ß-catenin mutations.

Familial Adenomatous Poliposys Italian Network (Rete Italiana Poliposi Adenomatosa Familiare)

RIPAF (Rete Italiana Poliposi Adenomatosa Familiare) is a national, multicenter observational registry designed to establish a coordinated Italian network for the management of Familial Adenomatous Polyposis (FAP) and related adenomatous polyposis syndromes. The registry includes patients with APC-related FAP (classic and attenuated forms), MUTYH-associated polyposis (MAP), and adenomatous polyposis not associated with APC or MUTYH mutations (NAMP), including cases linked to other susceptibility genes or without identified pathogenic variants. The study combines retrospective and prospective data collection across 28 Italian centers. Its primary purpose is to generate standardized, large-scale clinical data to better characterize disease presentation and evolution, evaluate current surveillance and surgical strategies, and assess oncological outcomes and quality-of-care indicators in real-world practice. The registry will collect detailed information on genotype-phenotype correlations, colorectal and upper gastrointestinal cancer incidence, desmoid tumor development, timing and type of prophylactic surgery, postoperative outcomes, and long-term survival. Additional objectives include evaluating adherence to surveillance guidelines, timing of genetic diagnosis, and preventive surgical uptake among at-risk relatives. By harmonizing data collection and promoting collaboration among referral centers, RIPAF aims to reduce variability in clinical management across Italy, improve risk stratification and decision-making, and create a national platform to support future multicenter research initiatives and international collaborations in hereditary colorectal cancer syndromes.
