Introduction: A gastric perforation is a form of hollow digestive organ perforation in which the entire thickness of the stomach wall is injured. Perforation of hollow organs can be suspected based upon the clinical picture, and the diagnosis becomes obvious through an image of free air on imaging performed. Methods: Data of patient characteristics were observed retrospectively from medical records of patients diagnosed with gastric perforation between January and December 2018. Results: Between January and December 2018, 45 patients with gastric perforation were identified, with data distributed by gender. There were 36 women (80%) and 9 men (20%) in the group. Based on the age group, 32 patients (71%) were distinguished by the age group over 40 years and 13 patients (29 %) under 40 years of age. When viewed from the location of the gastric perforations, it was found that 4 patients (9%) had a perforation in the antrum, 36 patients (80%) in the Prepylorus, and 5 patients (11.2%) in the major curvature. Data on analgesic use revealed 32 patients (71%) had a history of taking analgesics and 13 patients (29%) without a history of taking analgesics. Conclusion: In 2018, the majority of gastric perforation patients at Dr. Moewardi Hospital were female (80%), with the highest age group being over 40 years (71%) and the most gastric perforations occurring in the pylori (80%). The number of patients with gastric perforation who had previously used herbs and analgesics was higher (70%) than those who had not. Thus, the results of this retrospective study are consistent with previous research findings and can be used to continue research into the relationships (correlations) between the aforementioned variables.

AIM: This study aims to evaluate the effect of adjuvant chemotherapy on estradiol levels in patients with HER 2-overexpression breast cancer in a developing country. METHODS: This comparative study with pre- and post-design model observation approach, involving patients with HER 2-overexpression breast cancer who had undergone surgery and had never received chemotherapy or hormonal therapy before, who were then given adjuvant chemotherapy. Estradiol levels were measured before and after chemotherapy. The study was carried out in the surgical oncology division of RSUD Dr. Moewardi (RSDM) Surakarta from January 2020-December 2020. Descriptive data are presented in a frequency table based on age, menstrual status, parity status, breastfeeding status, contraception, contraception duration, family history, stage, and histological grade. Before and after chemotherapy in patients with breast cancer, the estradiol levels employed the paired sample t-test of the Wilcoxon rank test because the data did not meet the normality assumption. RESULTS: From the total data of 21 patients, 15 patients experienced a decrease in estradiol levels after chemotherapy, while six patients underwent an increase. The mean estradiol level before chemotherapy was 89.41 pg/ml, whereas the mean estradiol level after chemotherapy was 55.90 pg/ml. It indicates a difference in the decrease in estradiol levels of 33.51 pg/ml. The statistical test results also obtained a p-value of = 0.033 (p < 0.05), which signifies a significant difference between estradiol levels before and after chemotherapy. Thus, chemotherapy is effective in lowering estradiol levels in patients with breast cancer. CONCLUSION: Chemotherapy affects decreasing estradiol levels in patients with HER2 overexpression breast cancer.
