Active surveillance as the default for tiny papillary thyroid cancers
Papillary thyroid cancers under 1 cm almost never cause harm. Japanese hospitals have watched thousands safely. Make watching, not surgery, the default everywhere, with a registry.
Kuma Hospital and Cancer Institute Hospital (Tokyo) cohorts show under 1% distant progression and no disease deaths over decades of surveillance for low-risk papillary microcarcinoma. Propose making surveillance the default option in guidelines, with an international registry, a standardised ultrasound protocol, and reimbursement parity with surgery.
Hypothesis
Default surveillance reduces surgery for papillary microcarcinoma by at least 60% with disease-specific mortality unchanged and lower rates of hypoparathyroidism and nerve injury.
Rationale
Long-term Japanese outcomes have been replicated in US and Korean pilots.
What would test it
Registry-based comparison plus a randomised decision-aid trial on uptake of surveillance.
Maturity
being tested at scale

Bottlenecks it attacks
- Overdiagnosis and false alarms · Finding more cancer is not the same as saving lives. Screening also finds cancers that would never have hurt anyone, and treats them.
