Biomarkers are usually required to aid the selection of patients who will likely respond to a given targeted therapy. [6] Co-targeted therapy involves the use of one or more therapeutics aimed at multiple targets, for example PI3K and MEK, in an attempt to generate a synergistic response [5] and prevent the development of drug resistance.

Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.
Targeted alpha-particle therapy (or TAT) is an in-development method of targeted radionuclide therapy of various cancers. It employs radioactive substances which undergo alpha decay to treat diseased tissue at close proximity. [1] It has the potential to provide highly targeted treatment, especially to microscopic tumour cells.
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.

Monoclonal antibodies used to boost an anticancer immune response is another strategy to fight cancer where cancer cells are not targeted directly. Strategies include antibodies engineered to block mechanisms which downregulate anticancer immune responses, checkpoints such as PD-1 and CTLA-4 ( checkpoint therapy ), [ 20 ] and antibodies ...
Nuclear medicine encompasses various substances, either alone or in combination, that can be used for diagnostic imaging and targeted therapy. These substances may include ligands of receptors present on the target tissue or compounds, like iodine, that are internalized by the target through metabolic processes.
The use of drugs (whether chemotherapy, hormonal therapy, or targeted therapy) is systemic therapy for cancer: they are introduced into the blood stream (the system) and therefore can treat cancer anywhere in the body.
Examples include therapeutic cancer vaccines (also known as treatment vaccines, [13] which are designed to boost the body's immune system to fight cancer), CAR-T cells, and targeted antibody therapies. In contrast, passive immunotherapy does not directly target tumor cells, but enhances the ability of the immune system to attack cancer cells.
