Introduction and objective:
Testicular cancer is a rare cancer constituting approximately 1% of all cancers diagnosed in men worldwide. Simultaneously the burden of the testicular cancer increased in last decades, becoming the most frequent cancer diagnosed among adolescents and young males aged 14 – 44 years of live. Our study was aimed to present the epidemiology and assess the impact of COVID-19 pandemic on the testicular cancer morbidity in Poland.

Material and methods:
The secondary epidemiological data obtained from the National Health Fund of Poland regarding males aged over 20 years of life diagnosed with the testicular cancer who have obtained healthcare services in at least one of the over 250 specialized healthcare services provided to cancer patients were analysed. The incidence rate per 100,000 males standardized to the European Standard Population 2013 (SIR) was calculated divided into subregions, according to patients’ domicile.

Results:
In 2015 – 2021, the average national testicular cancer incidence rate remained stable, but in 2021, an almost 10% increase in incidence compared to 2020 was noted. Furthermore, an epidemiological analysis conducted at the subregional level pointed out an increase in testicular cancer incidence in 52 of the 73 subregions, with spatial differantiation. The largest increases in incidence were observed in the Żyrardów, Tychy, and Tricity subregions, with differences between the subregions with the lowest and highest incidence.

Conclusions:
The incidence of testicular cancer in Poland in 2015 – 2021 increased despite the pandemic restrictions and limited availability of in-patient healthcare services. The spatial differentiation of incidence’s annual percent change was also demonstrated identifying areas where health promotion and health education activities should be intensified.
