ABSTRACT
Background: Skin cancer is the most common type of cancer in most countries and it holds the first or the second place in terms of frequency in different areas of the country. BCC is the most usual type of tumor in the white skinned people, and its incidence rate rises as individuals get older, especially after age 40.Thistype of skin cancer mostly occurs in the white skinned people and, in85% of cases; it develops on the head and neck. This study aimed at examining the geographical distribution of skin cancer (BCC type) in Ardabil province through GIS. Methods: This cross-sectional study has been done on 131 cases of skin cancer with type BCC in 2007-2014. The required information such as age, sex, occupation, and the locus of BCC, was extracted from the patients' records based on their place of residence. Data analysis was performed using SPSS (version 20). ARC GIS (version 10) was used for drawing geographic maps. Results: 50.4% of the subjects were men and the mean age of them was 62.8±14.5 years. Of the subjects, 66.4% were from Ardabil city, 80.2% from urban population and 15.3% of the subjects were smokers. Of the patients, 78.5% had developed cancer in their face. Conclusions: Results showed that for control of cancer, educational interventions should be given priority, and people should be instructed about the use of personal protection equipment, like proper sunscreen cream, hat and sunshade in the workplace, as far as it is possible.
ABSTRACT
BCC and SCC are the most prevalent malignant non-melanoma skin tumors. BCC is the most common skin tumor in white-skinned people, and as one ages, after being 40 year-old, incidence rate of BCC increases. SCC has the next rank and is more common in middle-aged and old persons. The present study addresses the prevalence of melanoma and non-melanoma malignancies in patients visiting dermatology clinics in Ardabil during 2002-2013. Methods: This study was of retrospective descriptive type. Approximately out of 100000 medical records of patients visiting dermatology clinics, 371 cases were chosen. The selected cases had undergone biopsy on suspicion of malignancy and their pathological response was attached to the record. Data were analyzed through SPSS, version 19, and descriptive as well as inferential statistical tests were used. Results: The prevalence of malignant skin tumors was 0.37%. 48% of cases were male, and 52% were females. The mean age of patients was 62.4 with a standard deviation of 15, and individuals of 50-70 age range had the peak incidence (46.1%). BCC was the most prevalent lesion (72%). Nose was the most common area for skin tumors (35.6%). For BCC the mean age was 62 ± 14, and for SCC it was 64.6 ± 17. Conclusions: According to the results, BCC was the most prevalent tumor. Skin tumors were mostly observed among females, and the most common locus was nose.
