Pankreascancer kan metastasera tidigt : Tumörbiologi tycks viktigare än tumörstorlek

Pancreatic cancers are associated with poor survival and only some 10 per cent are resectable, but even in this subgroup recurrence is very frequent. The traditional view of sequential development of pancreatic cancer has been challenged by novel molecular biological findings, where the tumor quite rapidly might turn metastatic. In about 60 000 patients with diagnosed pancreatic cancer the association between tumor size, metastatic spread and survival was analyzed. Even the smallest tumors (
