The mTOR inhibitor everolimus failed to prove progression-free survival noninferiority compared with the VEGF-targeting tyrosine kinase inhibitor sunitinib when given as first-line treatment in patients with metastatic renal cell carcinoma.
The mTOR inhibitor everolimus (Afinitor) has been found to significantly reduce the size of angiomyolipomas, the slow-growing benign tumors commonly associated with tuberous sclerosis complex (TSC) and sporadic lymphangioleiomyomatosis, according to the results of the phase III EXIST-2 study.
Efforts to identify clinical biomarkers of response or resistance to mTOR inhibitors are ongoing. This review will summarize results of preclinical and clinical studies as well as ongoing clinical trials with mTOR or dual PI3K/mTOR inhibitors.
Such a systematic review of the current status of mTOR inhibitors in the treatment of breast cancer demonstrates holes in our knowledge of the role of the tumor, the host, and metabolic factors in breast cancer progression.
I see a time in the not too distant future when we’ll define tumors this way. What will our subspecialties be? Rather than a breast clinic or a lung clinic, will we perhaps be attending a “HER2 clinic” or an “mTOR clinic” instead?
Don Dizon, MD, Brown University, discusses the paradigm shift in the treatment of endometrial cancer with the use of medical therapy, including chemotherapy with biologics, mTOR inhibitors combined with chemotherapy, and targeted therapies.
