Targeted therapy for breast cancer treatment helps target cancer cells which grow out of control.
Cancers happen when our normal body cells start multiplying and grow out of control.
Targeted therapy for breast cancer treatment, is the administration of new age drugs which inhibit or block the uncontrolled growth of cancer cells.
Unlike regular chemotherapy which attacks all cells, good and bad, targeted drugs attack only specific cancer cells and inhibit growth.
They tend to have fewer and also different side effects than chemotherapy drugs.
Breast Cancers are caused by various mutants such as BRCA1, BRCA 2, PIK3CA. Each mutant requires a different targeted for control and treatment works better with targeted drugs even when traditional chemotherapy has limited value.
1 in 5 women with breast cancer, test positive for HER2/neu. Which means that the cancer cells have too much of a growth-promoting protein known as HER2/neu (or just HER2) on their surface.
These cancers, known as Her2/neu positive cancers tend to grow and spread more aggressively. A number of drugs have been developed that target this protein such as Herceptin or trastuzumab, Perjeta or TDM-1.
Most of these drugs are given as an IV infusion.
Breast cancers which are hormone receptor positive or ER, PR positive as they are commonly known, respond well to the addition of hormone therapy in addition to regular chemotherapy.
CDK4/6 inhibitors work well for hormone receptor positive and Her2/neu negative breast cancers.
Many of these drugs are in addition to regular chemotherapy and many are given post initial chemotherapy and even after radiotherapy.
The decision on drugs to be used depends on whether the woman is pre-menopausal, post-menopausal or still ovulating.
A good breast cancer specialist, a good medical oncologist helping with cancer treatment is necessary to take an overview based on age, diagnosis, genotype, and mutants.
