Abstract 32P


Worldwide breast cancer morbidity and mortality was still positioned in the top. Epidemiological data for breast cancer in Bali was not available although is essential for planning health measures. This study aimed to summarise the demographics of breast cancer subjects in Sanglah Genral Hospital from 2012-2019 and emphasize variables that related.


This is a descriptive study, collecting all breast cancer subjects data from January 2012 to 2019. All data from the cancer registry were analyzed and tabulated. Data were described as count and percentages. Reasoning analysis was done by looking at the counts from year to year. Information for counting age standardized rate was taken in national census data of population in Bali. Literature review if articles were also screened for the filtering out of the data regarding epidemiology of breast cancer in worldwide for comparison.


A total of 1627 cases from 2012 to 2019 were included in this study for analysis. The incidence of breast cancer increase from 187 cases to 364 cases from 2013 to 2016. The age-standardized incidence rate was 84.33 per 100.000 women Balinese population. Most cases were found in advanced stages, stage IIIB (29.38%) and stage IV (22.56%). The most common tumor status found was T4 (49.78%), N1 (41.49%), and 22.5% were found to have metastasis. Lung metastasis dominated all the metastasis cases with the rate of 42.35%. Majority of histopathology subtypes in breast cancer subjects were invasive carcinoma of non special type (NST) (78.8%), followed by invasive lobular carcinoma (12.4%). From 1627 subjects, only 1160 (71.3%) had subtype tested, with luminal B subtype dominated the cases (36.5%).


Geographical and phenotypical variations differ from breast cancer subject epidemiology. Thus, statistical data should be done in each region for a better diagnosis and treatment care.
