Every year, nearly 900,000 individuals worldwide are diagnosed with head and neck cancer, encompassing tumors from the oral cavity, pharynx, larynx, and other related structures. The heterogeneity within HNC—differing in location, pathology, and molecular profiles—makes it imperative to collect detailed clinical and biological data to understand tumor behavior and therapeutic response. Traditional registries have largely focused on basic characteristics, offering limited insight into tumor biology or treatment nuances. Moreover, many hospital cohorts suffer from selection bias due to non-consecutive patient inclusion. RONCDOC addresses these limitations with a robust methodology that guarantees consecutive and high-fidelity data capture directly from electronic patient files.

The innovative RONCDOC system integrates multiple data sources to build a comprehensive and verifiable dataset.
