Rare cancers are collectively common but each is too rare for normal trials. Link every rare cancer patient worldwide into one network with registries and trial designs built for small numbers.
Rare cancers make up roughly a quarter of cancer diagnoses and have worse survival; each is too infrequent for conventional trials and expertise is scattered. Networks such as EURACAN and the International Rare Cancers Initiative show partial solutions. The proposal is a global federated rare cancer network: a single patient-facing registration and referral pathway, standardised molecular workup, a shared registry with outcomes, and pre-agreed trial frameworks (Bayesian borrowing across related histologies, n-of-1 crossover designs, external control arms from the registry) accepted by regulators for approval decisions.
