In patients with localized disease, overall 5-year survival rates have improved to more than 80%?

In patients with localized disease, overall 5-year survival rates have improved to more than 80% with the combined use of surgery, radiation therapy, and chemotherapy.6 However, in patients with metastatic disease, little progress has been made in survival rates, with a 5-year event-free survival rate less than 30%. Does this mean that they only live for 5 years??
