“…Significant increase in melanoma incidence (from 5.1 in 1998 to 7.8 new cases per 100 000 inhabitants in 2008) was observed in Latvia and similar trend was observed in other European countries [2] where the estimated incidence of melanoma (measured per 100 000 inhabitants) varies form 19.1 in Northern Europe (NE) to 6.1 in Central and Easter Europe (CEE) with average value of 11.2 in whole Europe [3]. Melanoma mortality rates are much more similar -2.3 in CEE, 3.0 in NE and 2.3 in whole Europe.…”

The purpose of this paper is to offer a method for discrimination of cutaneous melanoma from benign nevus, founded on analysis of skin lesion image. At the core of method is calculation of mean and standard deviation of pixel optical density values for a few narrow spectral bands. Calculated values are compared with discriminating thresholds derived from a set of images of benign nevi and melanomas with known diagnosis. Classification is done applying weighted majority rule to results of thresholding. Verification against the available multispectral images of 32 melanomas and 94 benign nevi has shown that the method using three spectral bands provided zero false negative and four false positive melanoma detections. The proposed classifier is characterized by high sensitivity and specificity concerning statistical point estimates whereas its possible technical implementation is fairly simple. The proposed method may be instrumental for designing low cost diagnostic equipment to be used in primary care that is important for early detection of cutaneous melanoma.

“…The mean invasive MM Breslow thickness in this study was 1.29 mm (range 0.1–14.00 mm), suggesting that early detection was not compromised, despite the low NNT. The range in the literature is 0.72–6.00 . In our study, three patients had thick melanomas of 5.80, 7.40 and 14.0 mm.…”

“…Stratification of 103 patients with invasive melanoma in this study by staging and Clark invasion level showed that the major part of patients were diagnosed on (Azarjana et al, 2012), 2.7 in men and 3.5 in females in Belarus, 4.4 in men and 4.6 in females in Poland (Curado et al, 2007). Being in agreement with a recent research, this observation showed melanoma incidence rates to vary considerably within European countries with the highest rates in Switzerland (19.2/100.000) (Forsea et al, 2012).…”

Russian rates for melanoma incidence and mortality are relatively low as compared to some other white populations but the tumor is of increasing importance. In this paper, data are based on a retrospective descriptive analysis of melanoma epidemiology and clinicopathological characteristics in Krasnoyarsk Territory belonging to the Siberian Federal District of the Russian Federation. The age-adjusted incidence and mortality rates for the period 1996-2009 were determined with subsequent retrospective analysis of clinicopathological data of 103 primary melanoma cases. Our results showed that incidence and mortality rates in the region under consideration match the Russian national trends and correspond to epidemiological data of the countries of Eastern Europe. Stratification of melanoma cases by age, sex, clinicopathological state and localization revealed a prevalence of lesions on the trunk and lower extremities. Most melanomas diagnosed were of superficial spreading type and the third Clark's level of tumor invasion and stage II according to AJCC. In spite of comparatively low rates of incidence and mortality the trend to increase of melanoma cases in the region under consideration obviously calls for more attention and further investigation.

Melanoma epidemiology, prognosis and trends in Latvia

Abstract: There is a steady increase in melanoma incidence in Latvia with the majority of melanomas diagnosed at late stages with poor prognosis for survival.
