Story summary

A groundbreaking study in Nature Genetics uncovers that tumor metastases thrive on copy number alterations (CNAs), such as whole-genome duplication, instead of mutations. This clever adaptation allows cancer cells to dodge the immune system and withstand immunotherapy. Analyzing over 8,000 samples, researchers linked CNAs to worse survival rates and treatment outcomes, highlighting a critical challenge in cancer therapy.
