This is a type of drug treatment that attacks specific features of cancer cells, known as molecular targets, to stop the cancer growing and spreading. The molecular targets are found in or on the surface of cancer cells (for example, they may be genes or proteins).

When is targeted therapy used?
Targeted therapy can often be given by mouth as tablets or capsules. These drugs can be highly effective, but they will only work if the cancer contains the particular gene or protein and, even then, they do not work for everyone. Ask your oncologist about molecular testing and whether targeted therapy is an option for you.
Targeted therapy is currently available for people with NSCLC whose tumours have specific genetic changes (mutations) when the cancer is advanced or has come back after initial surgery or radiation therapy. This area of science is changing rapidly, and it’s likely that new mutations and targeted therapy drugs will continue to be discovered. Talk to your oncologist about clinical trials.
Cancer cells often become resistant to targeted therapy drugs over time. If the first-line treatment stops working, your oncologist may suggest trying another targeted therapy drug or another systemic treatment. This is known as second-line treatment.
Side effects of targeted therapy
Although targeted therapy may cause less harm to healthy cells, it can still have side effects. These vary depending on the targeted therapy drugs used – common side effects include:
- skin changes such as acne-like rash
- tiredness
- diarrhoea
- nausea
- vomiting.
It’s important to report any new or worsening side effects to your medical team. If left untreated, some side effects can become serious and may even be life-threatening.
