In patients with Merkel cell carcinoma (MCC), how reliable are Merkel cell polyomavirus antibody titers in identifying recurrence?In this cohort study of 503 patients with Merkel cell carcinoma, after a falling or negative titer, the chance of remaining free of recurrence over 3 months was 99.3%. In contrast, the risk of recurrence after a single rising oncoprotein antibody titer was 58% by 12 months.A rising oncoprotein antibody titer often precedes clinical or radiographic recurrence, prompting intensified surveillance, whereas a falling or negative titer has high negative predictive value, providing reassurance and potentially reducing the need for surveillance imaging.
