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

Objectives: To analyze the incidence and overall survival rate of patients with vulvar cancer in Poland, based on the reporting data from the National Health Fund.Material and methods: The incidence of vulvar cancer in Poland in 2008–2016 (9-year follow-up period) by voivodship and the number of patients undergoing combined hospital treatment were analyzed. For the group of patients treated systemically, overall survival (OS) probability was calculated using the Kaplan-Meier estimation method.Results: In the period 2008–2016 in Poland, the diagnosis of malignant neoplasm of the vulva (C51% group) was made in 29,702 patients. The mean annual prevalence rate per 100,000 inhabitants was 8.3 ± 1.2 for Poland. The largest numbers of patients were reported in Mazowieckie and Slaskie voivodeships and the lowest in Opolskie and Podlaskie voivodeships. The median overall survival of patients treated with the combined method in 2008–2016 in Poland was 64.7 months (95% Cl: 58.0–70.0). One-year survival rate was observed in 77.6% of patients, 2-year in 64.4%, 3-year in 58%, over 5 years — 54.22%.Conclusions: 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

Overall survival (OS) in patients after chemotherapy for cervical cancer in Poland in years 2008–2015

Objectives: To analyze cervical cancer prevalence as well as treatment methods, and its effects and assessment of overall survival of patients after chemotherapy for cervical cancer in Poland. Material and methods: Data were collected from the registry of the National Health Fund (the only public payer in Poland). The data of patients treated in 2008–2015, who were shown to the payer with the diagnosis of malignant neoplasm of cervix (C53 according to the ICD-10 classification), were included in the analysis. The annual and eight-year prevalence rates were calculated. The overall survival was calculated for patients treated with chemotherapy. Results: In the analyzed period (2008–2015), 83,100 women were diagnosed with C53, of which 33,300 (40%) were reported in the group of hospital treatment. The median age of patients was 59 years (58.8 ± 12.87). The highest prevalence rate was observed in 2008 (16.94 patients/100,000 inhabitants). The highest annual and period (2008–2015) prevalence rates patients per 100,000 inhabitants were observed in the Podlaskie (17.03 and 115.53 respectively) and Pomorskie (14.19 and 101.43 respectively) voivodeships and the lowest in Dolnośląskie voivodeship (10.47 and 78.87 respectively) and Podkarpackie voivodeship (10.79 and 71.29 respectively). Mean survival time was 55.12 months and its median 45.46 months. Annual survival time was observed in 76.79% of patients, 2-year in 60.61%; 3-year in 53.08% and 5-year in 46.65%. Conclusions: In the years 2008–2015 in Poland, the incidence of cervical cancer was even 4 times higher than the EU average, and the mortality was as much as 70% higher than the average for EU countries
