A new staging proposal for pulmonary metastases. The results of analysis of 5206 cases of resected pulmonary metastases.

Abstract

In 1991, the International Registry of Lung Metastases was formed by 18 thoracic surgery departments in Europe and North America. Statistical analysis of combined data from the Registry revealed significant variables in patient selection, which helped to guide treatment modalities for specific patients. A simple system of stage classification is presented in this article as a basis for discussions on future results and for clinical trial design.
