Analysis of cancer survival data and related outcomes is necessary to assess cancer treatment. The survival analysis, although considered a cornerstone of oncology papers, is the weak point for the interpretation of results when used without robust data, without verifying the conditions of usage, and without defining the terminology we are using; leading to missing the real message. Unfortunately, a lot of scientific papers dealing with oncology violates the assumptions necessary for the usage of these tests, consequently, the conclusions in these papers cannot be assumed by the methodology used.
