Metastasis to regional lymph nodes, after distant metastasis, is the most important prognostic factor of colorectal carcinomas. It is also of primary importance in decisions related to the administration of adjuvant treatments. Most scientific associations recommend the examination of at least 12 lymph nodes for the reliable determination of the absence of(More)
The assessment and interpretation of the results of a clinical study are a real challenge for the clinicians. In this paper we establish a general basis for a critical and reserved assessment of these, from the fundamental aspects of the design and statistics, as well as the application of the results to our own patients according to risk and benefit(More)
