What type of cancer is resistant to chemotherapy?
Most advanced cancers, including ovarian cancers, eventually become resistant to therapy.
Why do some cancers not respond to chemo?
Cancer cells may stop taking in the drugs because the protein that transports the drug across the cell wall stops working. The cancer cells may learn how to repair the DNA breaks caused by some anti-cancer drugs. Cancer cells may develop a mechanism that inactivates the drug.
Do all cancers respond to chemo?
Some cancers are very sensitive to chemotherapy. So it can work very well for them. But some types of cancer don’t tend to respond well to chemotherapy. In that case, your doctor isn’t likely to suggest it as a treatment for you.
Does cancer become resistant to chemotherapy?
Cancer has the ability to become resistant to many different types of drugs. Increased efflux of drug, enhanced repair/increased tolerance to DNA damage, high antiapoptotic potential, decreased permeability and enzymatic deactivation allow cancer cell survive the chemotherapy.
What is the most aggressive chemotherapy?
Doxorubicin (Adriamycin) is one of the most powerful chemotherapy drugs ever invented. It can kill cancer cells at every point in their life cycle, and it’s used to treat a wide variety of cancers.
What does it mean if chemo doesn’t work?
Your oncologist might suggest new treatments, such as trying different combinations of chemotherapy drugs that include experimental options. Still, you and your oncologist must consider whether more treatment will improve your health, or whether it’s best to stop treatment altogether and pursue palliative care.
What is palliative chemotherapy?
Palliative chemotherapy is treatment that is given in the non-curative setting to optimize symptom control, improve or maintain QoL and, ideally, to also improve survival.
What happens if you refuse chemotherapy?
Studies have reported rates of less than 1\% for patients who refused all conventional treatment [4] and 3\%–19\% for patients who refused chemotherapy partially or completely [5–9]. We tend to think that refusing therapy leads to a poorer quality of life as the disease progresses without treatment.
Why do some tumors become resistant to chemo?
Resistance can occur when cancer cells—even a small group of cells within a tumor—contain molecular changes that make them insensitive to a particular drug before treatment even begins. Because cancer cells within the same tumor often have a variety of molecular changes, this so-called intrinsic resistance is common.
What chemo is known as the Red Devil?
Can the red devil be defanged? Doxorubicin, an old chemotherapy drug that carries this unusual moniker because of its distinctive hue and fearsome toxicity, remains a key treatment for many cancer patients.
