Robson staging is inaccurate in predicting tumor behavior. Patients with tumors larger than 4 cm. and a normal contralateral kidney may be best served by radical nephrectomy rather than elective nephron sparing surgery. However, nephron sparing surgery may result in an outcome similar to that of radical nephrectomy for low grade, low stage renal cell carcinomas of 4 cm. or smaller.

Primary pulmonary synovial sarcoma is a rare primary lung tumor. Due to extensive size of the tumor with pleural and mediastinal invasion only a R1-resection status could be achieved by thoracic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
