Abstract

To evaluate the occurrence of melanoma in the period 1996-2017 in East Bohemia region in the Czech Republic. We studied the incidence of melanoma and the age of diagnosis (adjusted calculation) and the parameters such as histology, body site of lesions, the length of the duration of lesions in 2810 patients. No change in the occurrence of melanoma and in age of melanoma during this period was found. The difference between men and women was not confirmed in histology, but the difference between men and women was confirmed in the body site of lesion and in the length of duration of lesion. No relation between the length of duration of lesions from which melanoma had originated and its histology was confirmed. The relation was confirmed between histology and body site of melanoma. The relation between the body site and the length of duration of previous lesions was confirmed also. The increasing occurrence of melanoma on the trunk according to the duration of the previous lesions was confirmed.

Highlights

Melanoma is one of the most malignant skin tumors with constantly rising incidence worldwide, especially in fairskinned populations [1,2,3]
We evaluated the relation between the histology and the body site of melanoma
We evaluated the relation between the duration of lesions (0–4 years, 5–9 years, over 9 years, from childhood) and the body site of melanoma

Summary

Introduction

Melanoma is one of the most malignant skin tumors with constantly rising incidence worldwide, especially in fairskinned populations [1,2,3]. Melanoma was a rare cancer, but in the last 50 years its incidence has risen faster than almost any other cancer. Skin cancer (the majority attributed to melanoma) was the cause of almost 2000 deaths in Australia in 2010 and it is current ly the most common cancer in young Australians aged 15 to 39 years [4,5,6,7]. In the United States alone, 87,110 indi viduals were predicted to be diagnosed with melanoma in 2017 [2, 5]. More recently developed im munotherapeutic treatments combined with radiation can improve survival further to several years [9]
