We believe it is unethical to recommend this assay to individuals like a testing test, because its harms would outweigh any (unproven) benefit in avoiding tumor mortality [1].

However, due to methodological flaws, we believe that the true level of sensitivity and specificity of the assay are lower than offered in the study. Testing appears to have been carried out in independent batches for malignancy cases and healthy settings without blinding, leaving results vulnerable to bias from batch effects. The instances and settings lack a common resource human population, but were pooled for AUC analyses which also omitted organizations with EGFR-IN-7 undesirable results post-hoc. No details are provided regarding the healthy settings, whose demographic and health EGFR-IN-7 characteristics could impact the specificity estimate. Details will also be lacking for laboratory methods, assay reproducibility, and validity as compared with standard assays. No pre-diagnostic sera were analyzed to address early detection [2], [3], [4], [5], and for malignancy recurrence, statements for utility were based on a single patient. Formal statistical comparisons are lacking and many confidence intervals are omitted. The authors statement 27% seroprevalence of HPV16 L1 DRH1 antibodies in young women, and all vaccinated individuals in the study were EGFR-IN-7 strongly seropositive. This demonstrates seropositivity reflects not only tumor-related antibodies, but also natural illness and vaccine-induced antibodies. Consequently, the assay could not be used to detect malignancy or malignancy recurrence in vaccinated individuals, or among people with unknown vaccination status.
