BackgroundCutaneous melanoma is a skin cancer with low incidence but high mortality rates. The South region of Brazil has the highest death rates by melanoma per 100,000 inhabitants of the country. Little is known about the spatial distribution of this malignancy in southern Brazil.ObjectivesIdentify the spatial patterns of deaths from cutaneous melanoma in South region of Brazil, using geoprocessing tools.MethodsThis is an ecological and exploratory study of death information by cutaneous melanoma obtained from portal Datasus, for Brazil's southern region, from January 2008 to December 2012. Deaths were separated by gender and rates per 100,000 inhabitants were calculated and used to compile thematic maps, Moran maps and Kernel maps, using TerraView software. It was adopted an alpha = 5%.ResultsThere were data on 2378 deaths from cutaneous melanoma in the study period. High rates were identified in the northern and littoral regions of Rio Grande do Sul; the northeast of Santa Catarina; and west of Paraná - for the total population, with minor differences detected and indicated regarding gender. The global Moran index presented p-values of 0.03, 0.04 and 0.03, respectively, for male, female and overall deaths. All the micro-regions that showed high priority for intervention were detected in the Rio Grande do Sul.ConclusionSpatial clusters of micro-regions with high death rates from cutaneous melanoma in South region of Brazil were identified, serving as an important tool for health managers.

“…Their research highlighted that the risk was incredibly signi cant for the coastal region and for body sites like the face and neck that are typically linked to high accumulated exposures, particularly in the male gender (15). In the study of Amancio and Nascimento (2014), spatial clusters of cutaneous melanoma incidence in Sao Paulo at the district level were identi ed. The researchers applied geostatistical techniques in addition to TerraView software to generate Moran maps, thematic maps, and Kernel maps.…”

Introduction: Skin cancer is among the most common cancer categories with an increasing global trend of incidence rate. This study explores the spatial distribution of skin cancer, considering body sites exposed and not exposed to sunshine separately. Methods: We used 4302 skin cancer cases recorded by Fars Cancer Registry in southwestern Iran for over six years (2011-2017). The variables included in the study were patients' residence address, gender, age, report date, and final topographical code. The patients' addresses were geocoded to the counties of the study area. Skin cancer sites were categorized based on sun exposure in male and female cases. We used the empirical Bayesian smoothing approach to estimate the skin cancer incidence rate at the county level. Finally, Anselin's Local Moran's Index was used to identify the high-risk skin cancer occurrence areas. Results: In general, skin cancer incidence increased in the study area over the study period (mid-March 2011 to mid-March 2017). Out of 4302 patients with skin cancer, 2602 cases (60%) were male. The age- and sex-specific rate of reported cases with skin cancer was higher in the 80-89 age group (in both male and female genders) compared to other age groups. There were some high-risk spatial clusters of skin cancer in the study area. Further investigations are required to identify the underlying cause of the formation of these clusters.Conclusions: Patients exposed to sunshine, especially among the male group, experienced much higher rates of cancer occurrence as compared to unexposed individuals. With a heterogeneous spatial pattern, hotspots were identified in non-sun-exposed and sun-exposed categories in the study area. Researchers and policymakers can significantly benefit from the spatial analyses of skin cancer incidence. These analyses can provide useful and timely prevention policies as well as tailored monitoring techniques in high-risk regions.

“…Such activities combine such exposure to high incidence of this radiation. Another important factor is represented by the historical construction of Brazilian population, with European ascendency in some regions (mainly the South 6 ) and indigenous and Afro-American ascendency in other regions due to colonization (North and Northeast).…”

Melanoma is the main serious skin cancer, due to its high lethality. This study aimed to make projections and analyze melanoma mortality trends in Brazil. Mortality Information System data were utilized for the period 1998-2012, which were projected until 2032, using the age-period-cohort model, with software R. The analysis of trends was made by Joinpoint regression, with 95% confidence interval, estimating the annual percentage change. It was revealed higher amounts of deaths in men for all regions. Brazilian trends presented reductions in men (APC = -0.4; CI95% = -0.6; -0.1; p < 0.01) and in women (APC = -0.8; CI95% = -0.9; -0.7; p < 0.01). The Midwest region presented increases for both sexes, while the Southeast region presented reducing trends for both sexes. In the North, there was stability for men and increases followed by stability in women, while the South presented reductions in men and stability in women; finally, the Northeast revealed one joinpoint per sex, with an increase followed by stability in men, and stability followed by reducing trends in women. The highest rates of the country were found in the South and Southeast regions, however, with reducing trends throughout time. Higher mortality trends in men were associated with later diagnoses in this group.
