Abstract

Background Head and neck squamous cell carcinoma (HNSCC) is the sixth most frequent malignancy worldwide. Immunotherapy with checkpoint inhibitors such as anti-CTLA-4 anti-PD-l and anti-PD-L1 has shown promising results in treating patients with recurrent/metastatic HNSCC. We aimed to systematically review the literature on immunotherapy with checkpoint inhibitors as treatment for advanced HNSCC.Methods PubMed, EMBASE, Google Scholar, and the Cochrane Library were systematically searched with the purpose of identifying all studies addressing the effects of checkpoint inhibitors as treatment for HNSCC in human clinical trials. We assessed effects of the treatment with checkpoint inhibitors on overall survival (OS), progression-free survival (PFS), HPV-status, PD-L1-status, and adverse events.Results We identified eight studies (n = 1431 patients) with an OS ranging from 7.5 to 14.9 months in PD-1 checkpoint inhibition. Two studies (n = 541 patients) observed a significantly (p = 0.01) and (p = 0.007) longer OS with checkpoint inhibition compared to standard-treatment, platinum-based chemotherapy (7.5 versus 5.1 months and 14.9 months versus 10.7 months). Two studies (n = 411 patients) found an increased OS associated with PD-L1-postive patients compared to PD-L1-negative patients. The eight studies have heterogenous design with only three being randomized.Conclusion Few clinical trials have investigated the treatment with checkpoint inhibition for HNSCC. Solely, two randomized studies comprising 240 patients treated with nivolumab (anti-PD-L) and 301 patients treated with pembrolizumab (anti-PD-L) showed a significantly prolonged survival in patients with recurrent/metastatic HNSCC compared with standard-treatment. There is a further need for randomized clinical trials investigating a putative role of checkpoint inhibition in the treatment of advanced HNSCC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
