Interval cancers in nasopharyngeal carcinoma screening: comparing two screening intervals after a negative initial screening result

Conclusions
The incidence of NPC, especially aggressive NPC, was low during the first few years after a negative screening; the incidence increased to the general population level afterwards. A screening interval of 4–5 years may therefore be more suitable than 9–10 years after a negative VCA-IgA test in NPC screening.
