TL;DR: The ability of circulating tumor DNA (ctDNA) to detect tumors in 640 patients with various cancer types was evaluated and suggested that ctDNA is a broadly applicable, sensitive, and specific biomarker that can be used for a variety of clinical and research purposes.

TL;DR: Overall survival following nivolumab treatment in patients with advanced treatment-refractory melanoma compares favorably with that in literature studies of similar patient populations, and responses were durable and persisted after drug discontinuation.

TL;DR: First-line therapy with pembrolizumab in patients with advanced Merkel-cell carcinoma was associated with an objective response rate of 56% and effectiveness was correlated with tumor viral status, as assessed by serologic and immunohistochemical testing.

TL;DR: It is found that dual therapy results in long-term disease control for most patients, if there are no single mutations that cause cross-resistance to both drugs; in patients with large disease burden, triple therapy is needed.

TL;DR: These data represent the most prolonged observation to date of patients with solid tumors responding to anti- PD-1 immunotherapy and the first report of successful reinduction therapy following delayed tumor progression, and underscore the potential for immune checkpoint blockade with anti-PD-1 to reset the equilibrium between tumor and the host immune system.
