More Therapeutic Roads When The Breast Tumors Switches To HER2-Low

The research that tumors in the breast can be evolved to a low HER2 increase the number of certified patients who can get benefit from the agents of investigation, which are generally novel anti-body conjugate drug therapies that are present in the clinical trials for the low HER2 tumors.

The very study of its kind explored how cancer in the breast evolves from primary to recurrent tumors has found that 30 percent of the cancer patients get converted from human epidermal growth factor receptor, which is the HER2 low state.

The study also found out that 14 percent of the triple-negative cancers in the breasts with the negative expression of HER2 in the stages of primary tumor converts to HER2 low symptoms in the tumor, which is recurrent possible opened the gates to cure such hard to treat cancer.

The researchers of breast cancer divided the study into different categories. (HR+)/HER2 negative or also known as luminal-like and (HR+)/HER2 positive or also known as triple-negative or negative for excess HER2 proteins, progesterone receptors, and estrogen receptors.

HER2 low implies HER2 tumors, which are negative with comparatively low expression of bio mark. Almost 50 percent of the cases studied under breast cancer are classified as HER2 negative, which falls under the category of low HER2. Dr. Federica Miglietta, who presented the findings at the ESMO breast cancer, stated that the results which they found give knowledge regarding how HER2 tumors may evolve in subgroups. This can challenge the present dichotomy established between the HER2 positive and the HER2 negative expressions of breast cancer.

She said that researchers now need to focus more on the insights and the study of the HER2 low expressions of the tumor since it can lead to the findings for the options of new and tested scientific therapies to treat the patients who are presently in trial and hopefully at the clinics in the upcoming days. She exclaimed that several Clinical trials are already going on the HER 2 low expressions of Breast Cancer.

A total of 29 percent of the findings of recurrent breast cancer showed the changes or development either from or to the HER2 low expression. HER2 low was seen around the percentage of 34 to 38 in the primary tumors and the relapse tumor, respectively. Around 15 percent of the HER2 negative tumors changed to HER2 low, and around 14 percent of the HER low tumor changed to HER2 negative tumor.

Dr. Aleix Prat, who is the Head of medical oncology at a clinic, claimed the substantial nature of the HER2 low expression. He said that the researchers need to study the finding thoroughly to determine the responses to the treatment among different patients. The question arises that is the HER2 in the primary tumor important more than the metastatic biopsy? Whatsoever be the result of the research, it is sure that in the upcoming years, we will have adequate data for the analysis.
