Why is Chemo considered a systemic treatment?
Chemo is considered a systemic treatment because the drugs travels throughout the body, and can kill cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumor. This makes it different from treatments like surgery and radiation.
How does chemotherapy work to treat cancer?
It works by keeping the cancer cells from growing and dividing to make more cells.

Some drugs work best when given continuously over a set number of days.

What drugs are used to treat acute leukemia?
These drugs induce differentiation of cancer cells. All- trans -retinoic acid and arsenic are capable of curing acute promyelocytic leukemia. Other drugs in this class include hypomethylating drugs, such as azacitidine and decitabine, and drugs with target mutations that block differentiation. Examples include enasidenib and ivosidenib, which counteract mutations in IDH2 and IDH1. Another approach uses venetoclax, which reverses a differentiation block caused by BCL2. Differentiating drugs are ineffective in most cancers.

How do antimitotics work?
Antimitotics work by disrupting the formation of spindles, which are needed to fully separate a cell that has undergone cell division into two new cells. Antimetabolites work by placing counterfeit bases into DNA so that those genes do not work properly and cell division does not occur. Antitumor antibiotics also damage the DNA and interrupt both DNA synthesis and RNA synthesis. Alkylating agents cross-link DNA so that it cannot separate.
