The present review synthesizes current evidence to outline the benefits of WaW while critically examining its inherent challenges. A comprehensive analysis interrogates the dualistic nature of WaW. It can provide favorable survival (5-year overall survival of 85% and cancer-specific survival of 94% in the International WaW Database) and meaningful quality-of-life improvements by avoiding radical surgery; concurrently, it embodies substantial risks due to the inherent imprecision of clinical complete response (cCR) assessment (a 10-25% discordance with pCR), a marked local regrowth rate (~25%) and unresolved long-term oncological uncertainties. In the present review it is argued that successful implementation of WaW depends on transcending current limitations through technological integration. Circulating tumor DNA is a promising but still investigational biomarker that may enable dynamic risk stratification; however, its clinical utility requires prospective validation. In conclusion, WaW has evolved from a radical concept to a reasonable, evidence-supported option within a precision oncology framework for a meticulously selected patient cohort, contingent upon rigorous multidisciplinary team assessment and an unwavering, structured surveillance protocol.

In the present review, findings from novel multi-omics studies were integrated to reframe PNET biology through the perspective of TME co-evolution. The present review highlighted how genomic instability serves as a key driver, promoting transcriptomic reprogramming and clonal evolution that subsequently remodels the TME into an immunosuppressive niche rich in cancer-associated fibroblasts and characterized by immune exclusion.
