Medicine & Evidences

The clinical decision process used into cancer diagnosis and treatment is based on evidences. Papers published in peer-review journals create sustained grades of recommendation. The most accurate data comes from randomized clinical trials and metanalysis. When browsing the following icons, you will better understand the clinical decision process.

  • Oncology is a medical specialty whose knowledge is systematized. Medical knowledge can be divided into standard and experimental. Standard knowledge means the one already globally recognized as the best option available at the moment. Experiential knowledge is a technical and ethical well-designed project that might or might not be useful, since it is still in a trial phase.

  • The physician is the only professional qualified to judge and guide the patient into a standard or experimental cancer treatment. The decision process requires very specific knowledge, often discussed in many international scientific meetings, requiring continuous updating. The right treatment's recommendation is the most important step in achieving the specific disease's expected outcome.

  • The clinical oncologist knows how to categorize medical knowledge in levels of evidence, which is very important for the safety of the recommendation. These levels of evidence are presented in cancer diagnosis, staging, treatment and prevention. There are international classifications that categorize the levels of evidence. They are based on the type of clinical trial, its methodology and statistical power, which will define a degree of recommendation.
