Abstract
BackgroundThe body site location of primary Malignant Melanoma (MM) has been correlated with prognosis and survival. Ethnic, genetics, sun exposure factors are related to the anatomical distribution of MM. Low and high socioeconomic strata in Chile differ in ethnic, genetic and cultural conditions. The purpose of this study was to analyze the anatomical MM distribution in the Chilean population in both strata searching for differences due to their ethno-genetic-cultural differences. Records of 1148 MM, 575cases from state hospitals (Low Socioeconomic Strata, LSS) and 573 cases from private clinics (High Socioeconomic Strata, HSS) were analyzed by body site.ResultsFemales from LSS showed a higher number of MM in soles, cheeks, and around the eye area. Females from the HSS showed a higher number of MM in dorsal feet and dorsal hands. Males from LSS showed a higher number of MM in soles, around the eye area, and cheeks. However, males from HSS showed a higher number of MM in the trunk, and in the arms. Acral MM was significantly higher in LSS than in the HSS in both sexes. The Chilean population from the HSS and LSS showed differences in the distribution of MM by site. Furthermore, gender differences in the proportion of MM analyzed by anatomical site are observed in both strata.ConclusionsResults show evidence that differential genetics factors, sun exposure, or other environmental or cultural factors of both strata may account for these differences.
Highlights
The body site location of primary Malignant Melanoma (MM) has been correlated with prognosis and survival
Because prognosis and survival of MM has been related to anatomical location we considered it important to analyze the anatomical MM distribution in the Chilean population seen in public and private healthcare services due to the different ethnic composition of populations of both strata
Despite notable limitations mainly due to the fact that this is a retrospective study with data bank files and we cannot access further data on the patients, we have established that the anatomical MM distribution in the Chilean population seen in public and private healthcare services is different, we showed that acral MM was significantly higher in LSS that in the health system (HSS)
Summary
The body site location of primary Malignant Melanoma (MM) has been correlated with prognosis and survival. Low and high socioeconomic strata in Chile differ in ethnic, genetic and cultural conditions. The purpose of this study was to analyze the anatomical MM distribution in the Chilean population in both strata searching for differences due to their ethno-genetic-cultural differences. Records of 1148 MM, 575cases from state hospitals (Low Socioeconomic Strata, LSS) and 573 cases from private clinics (High Socioeconomic Strata, HSS) were analyzed by body site. Anatomic location of MM differs according to the race and gender of the patient. The anatomical location of primary cutaneous MM has been correlated with prognosis and survival. Patients with MM located on the soles show poor prognosis and poor survival (five year survival rate of 35%) [6].
