What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Long-term survival trends by cancer type and treatment era.
A cohort study of 500,000 cancer patients diagnosed from 1975 to 2020, tracking 5-year survival rates by cancer type and correlating with treatment modalities introduced over time.
Efficacy of new treatments on survival for specific cancers.
An RCT comparing immunotherapy vs. standard chemotherapy in 1000 patients with advanced hematologic malignancies, measuring 5-year survival as a primary endpoint.
Current survival rates by cancer type.
A cross-sectional analysis of US cancer survival data from 2014-2020, reporting 5-year relative survival rates overall and by cancer type.
