Treatment of colorectal cancer stays in the focus of medical attention due to the high prevalence of pathology and complicated diagnosis making. Systemic therapy is becoming more asked-for as it can be administered instead of invasive interventions and has proven its efficacy at the advanced cancer stages.
Chemotherapy is the most studied type of systemic treatment. It has been applied in the clinical practice for over a few decades. Chemotherapy for colon cancer treatment in Germany includes the administration of both innovative and conventional chemotherapeutic agents with the best safety and effectiveness profiles.
When chemotherapy is performed
According to the colon cancer stage, therapeutic aims, patient’s age, and general health state, chemotherapy is given in the following modes.
Neoadjuvant chemotherapy is administered prior to surgical intervention. It shrinks the tumor so that the specialist can remove it completely or with fewer surgical complications. In certain cases, chemotherapeutic agents are given along with radiation therapy, as they make the tumor more sensitive to the irradiation.
Adjuvant chemotherapy is administered after surgical intervention. Its main aim is to kill cancer cells that may have been missed. These include pathological foci in the liver or micrometastases in the other localizations. Adjuvant chemotherapy is a measure of relapse prevention.
Palliative chemotherapy is administered when the tumor is advanced and has already spread to distant organs. Its aim is prolonging life and alleviating symptoms. Palliative chemotherapy is performed in specialized hospitals or, sometimes, on an outpatient basis.
