In general, chemoprophylaxis should be initiated only when the benefits of treatment outweigh the risks. The cost associated with chemoprophylaxis may be prohibitive, particularly when the cost of treatment is high or the incidence of the target disease is low. Many forms of chemoprophylaxis are therefore not cost-effective.
A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations. In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy. The majority of drugs used in cancer chemotherapy are cytostatic, many via ...
Salvage chemotherapy or palliative chemotherapy is given without curative intent, but simply to decrease tumor load and increase life expectancy. For these regimens, in general, a better toxicity profile is expected. [6]: 55–59 All chemotherapy regimens require that the recipient be capable of undergoing the treatment.
Targeted therapies may also be described as "chemotherapy" or "non-cytotoxic chemotherapy", as "chemotherapy" strictly means only "treatment by chemicals". But in typical medical and general usage "chemotherapy" is now mostly used specifically for "traditional" cytotoxic chemotherapy.
Antimicrobial chemotherapy is the clinical application of antimicrobial agents to treat infectious diseases. There are five types of antimicrobial chemotherapy: [citation needed] Antibacterial chemotherapy, the use of antibacterial drugs to treat bacterial infections; Antifungal chemotherapy, the use of antifungal drugs to treat fungal infections
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

Besides chemotherapy, medical oncology (pharmacotherapy for cancer) includes several noncytotoxic classes of therapy, such as hormonal therapy and targeted therapy (biologic therapy). Those agents are described in the relevant articles.
Despite this, many chemotherapy treatments can also suppress the immune system by causing lymphopenia or impairing lymphocyte function. Integrating immune-based therapies with chemotherapy has the potential to alter the body's overall environment and the local tumor microenvironment, disrupting immune tolerance and suppression pathways.
