Newer drugs to control a few of these effects have already been developed. Systemic chemotherapy is normally prescribed and overseen by an expert known as a medical oncologist. The severity of unwanted effects varies by person. For unknown reasons, some individuals tolerate chemotherapy much better than others. Probably the most common side effects of systemic chemotherapy include vomiting and nausea, reduction of appetite, hair thinning, sores within the mouth area or in the digestive system, feeling exhausted or lacking energy , elevated susceptibility to infection , and easy bruising or bleeding .Finally, an individual subject matter's network expression value measured prior to the treatment predicted his/her subsequent blinded response to sham treatment. This shows that this novel image-centered way of measuring the sham-related network can help reduce the amount of topics designated to sham treatment in randomized scientific trials for human brain disorders by excluding those topics who will display placebo results under blinded conditions.
