Letter From the Editor - May

Dear JITC Readers,

Welcome to the latest edition of the JITC Digest. Astute readers have likely noticed that this month’s digest is debuting a new feature. In addition to the usual programming—exciting new publications in JITC—the digest will now also highlight popular papers from the journal archive.

 

This month, we have four original research articles that offer novel insight on one of our field’s most challenging obstacles: resistance to therapy. Addressing immunotherapy resistance is a priority for the field as a whole, and the Society for Immunotherapy of Cancer is spearheading efforts toward developing uniform clinical definitions of resistance as well as support the basic and translational research in order to understand and overcome the mechanistic underpinnings.

 

Barbara Manzanares-Martin and colleagues reveal a surprising association between genomic heterozygosity for the killer-cell immunoglobin-like receptor and overcoming KRAS mutation-mediated resistance to cetuximab.

 

Disease that develops resistance to anti-PD-1 therapies is often highly challenging to treat, but results from two early phase trials in this month’s digest may offer patients new options. Brendan D Curti et al show safety and promising efficacy with the combination of a novel galectin antagonist and pembrolizumab for melanoma and head and neck cancer. Intratumoral injection of the oncolytic poliovirus PVSRIPO led to complete regressions even in uninjected lesions in some patients with melanoma in a phase I trial reported by Georgia M Beasley et al.

 

Finally, Michael W Knitz and colleagues provide deep mechanistic characterization of the interplay between dendritic cells and regulatory T cells that causes head and neck cancers to remain stubbornly immunologically cold after radioimmunotherapy.

 

Be sure to browse this month’s highlight of classic papers as well as the new original research—perhaps perspective from the archives may help spark novel insight into a new finding or vice versa.

 

Best regards,

Pedro J. Romero, MD
Editor-in-Chief, Journal for ImmunoTherapy of Cancer
