Cytostatic and/or cytotoxic chemotherapy
The logic of chemotherapy on malignant tumors is that it is possible to selectively inhibit the growth of a malignant cell without significantly damaging the healthy tissues and organs of the patient. However, not all locations and forms of malignant tumor are equally sensitive to chemotherapy drugs.
Rational chemotherapy is adapted to the case it is treating. The treatment regimen can be intense, causing significant side effects, toxic or even non-toxic. Repeat courses are typical, but the intervals between the courses are determined by the nature of the treated case as well as the side effects of the drugs. The efficacy of antitumor drugs is evaluated after each course of treatment, normally after 2-4 weeks.
The use of therapeutic drugs, particularly at relatively large doses, can mean the occurrence of side effects. These may be immediate (e.g. nausea, vomiting, allergic reactions), short-term (leukopenia, thrombocytopenia, diarrhea, stomatitis) or long term as a result of prolonged drug use (nephrotoxicity, cardiotoxicity, neurotoxicity, ototoxicity, etc.). Side effects are carefully monitored, and are important in the planning of further chemotherapy.
Targeted chemotherapy or "smart" chemotherapy drugs
Smart chemotherapy, also known as targeted treatment, is a medical treatment for cancer. The drugs used in this case belong the category of 'smart drugs'.
The difference between classical chemotherapy and targeted chemotherapy is that 'smart' drugs can clearly identify mutating cells, and can therefore exert a destructive effect exclusively on the malignant neoplasm without affecting healthy organs or tissues. These drugs are less toxic than the drugs traditionally used in chemotherapy, and therefore they can be used in those cases when the other drugs are contraindicated for the patient.
Treatment of cancer with the help of modified drugs of the target therapy is successfully carried out in Turkey.
