The Current Status of the Evidence of Malignant Tumours of the Eye and its Adnexa (dg. C69) in the Slovak Republic and in the Czech Republic

The area of ophthalmooncology includes not only intraocular tumors but also adnexal and extraocular tumors, relatively rare malignancies. To get valid data and to study the incidence, diagnosis and treatment is extremely difficult. The most frequently occurring intraocular tumor in adults is malignant melanoma, in children it is retinoblastoma. We present the results of the nationwide group of patients based on the diagnosis report C69 – Tumors of the eye and adnexa according to data of the National Cancer Registry in Slovak Republic. We monitor the incidence, distribution by age group, survival and staging. In the second part of the thesis analyzed data are compared with the data from Cancer
Registry in the Czech Republic. After analyzing the data, we found that the incidence of intraocular tumors have been reported to be comparable with neighbouring countries. The classification of the disease in different stages due to TNM classifying in the report is below 50 % in Slovakia. The incidence observed in each year ranges from 0.6 to 1.0 per 100 000 inhabitants. Survival of patients with dg. C69 is comparable with other countries. The proportion of clinically defined stages of the disease is in the database of Slovakia lower than in the Czech Republic. The delay of inserting data of patients in the National Cancer Registry in Slovakia and the availability of data for analysis is currently unsatisfactory. In Slovakia are available data only up to year 2003, in Czech Republic up to year 2009.a
