PD-L1 testingImmunotherapyImmune checkpoint inhibitorsPurpose of Review Atezolizumab has emerged as a novel treatment in patients with triple-negative breast cancer showing unprecedented survival gain. This breakthrough benefit is exclusively observed in PD-L1-positive patients, but PD-L1 positivity still ...
Programmed death ligand-1 (PD-L1) has been recently adopted for breast cancer as a predictive biomarker for immunotherapies. The cost, time, and variability of PD-L1 quantification by immunohistochemistry (IHC) are a challenge. In contrast, hematoxylin and eosin (H&E) is a robust staining used...
Next, we assessed treatment-induced changes by carboplatin and anti-PD-L1 within the tumor microenvironment of ILC metastases. Using CIBERSORTx immune cell deconvolution34, we observed increased CD8+T cells during anti-PD-L1 treatment, most notably in the patient with a durable response (Fig.4c)...

Breast cancer Melanoma When is it ordered? PD-L1 testing is ordered when you have been diagnosed with cancer and your healthcare practitioner wants to determine whether you would likely be a good candidate for treatment with a PD-L1 or PD-1 inhibitor. ...
What is the best practical scoring scheme for PD-L1 expression in breast cancer? PD-L1 expression scoring currently plays a significant role in the immunotherapy for an increasing number of advanced carcinomas23,24,25. Nevertheless, standardization of this subjective testing has not been achieved. ...
