Analysis of incidence and overall survival of patients with vulvar cancer in Poland in 2008-2016 - implications for cancer registries.

In the years 2008-2016 in Poland, based on the data reported to the National Health Fund, the incidence of vulvar cancer was 4 times higher than the statistics of the National Cancer Registry, the WHO or the USA, which indicates either substantive or reporting errors. In Poland, 54% of patients treated with the combined therapy survive over 5 years which is a much lower result compared to highly developed countries.
