“Neoadjuvant immunotherapy with the PD-1 inhibitor nivolumab is safe and feasible prior to surgery for early lung cancer, researchers reported at the ESMO 2016 Congress in Copenhagen.
” ‘Until now nivolumab and the other anti-PD-1 and anti-PD-L1 drug studies have only been reported in metastatic or advanced lung cancer,’ said lead author Dr Patrick Forde, Assistant Professor of Oncology, Sidney Kimmel Comprehensive Cancer Centre, Johns Hopkins, Baltimore, US. “This was the first study of neoadjuvant PD-1 blockade in early stage lung cancer.”
“All 13 newly diagnosed breast cancer patients with BRCA mutations had their tumors shrink significantly when treated with a PARP inhibitor ahead of frontline presurgical chemotherapy in a pilot study at The University of Texas MD Anderson Cancer Center.
“Tumor shrinkage after two months of treatment with the PARP inhibitor talazoparib, measured by ultrasound, ranged from 30 to 98 percent with an average reduction in tumor volume of 78 percent among the 13 patients.”
