Prognostic Factors of Non-epithelial Ovarian Cancer in a Tertiary Hospital in Indonesia

@#Introduction: Non-epithelial is a rare type of ovarian cancer but the most common ovarian neoplasm in reproductive age. This study analyzed the correlation of clinical characteristics to disease-free survival (DFS) and 3-year survival in non-epithelial ovarian cancer. Methods: A cohort analysis of medical records of 30 patients with non-epithelial ovarian cancer from 2016 to 2017 at Dr. Soetomo General Academic Hospital. Survival analysis was performed using Kaplan–Meier test, log-rank test, and Cox regression to determine the correlation of characteristics including age, stage, tumor size, tumor residue, histopathology type and chemotherapy status as prognostic factors for recurrence and mortality. Results: DFS was significantly affected by stage (p=0.049), tumor residue (p<0.0001), and chemotherapy (p=0.005). Stage I, no residual disease, and adequate chemotherapy had the highest DFS and mean DFS rates (94.1% and 35.6 months; 95.5% and 35.7 months; 75% and 31.94 months, respectively). Highest recurrence rates were found in patients with unstaged disease (hazard ratio [HR]=10.08), residue >0 cm (HR=23.13), and inadequate chemotherapy (HR=6.55). Three-year survival was significantly affected by stage (p=0.001), tumor residue (p<0.0001), and chemotherapy (p<0.0001). Stage I, no residual disease, and adequate chemotherapy had the highest 3-year survival rate and mean survival time (94.1% and 35.47 months; 95.5% and 35.7 months; 87.5% and 33 months). The highest mortality were found in patients with unstaged disease (HR=19.99), residue >0 cm (HR=11.33), and inadequate chemotherapy (HR=11.71). Conclusion: Stage, tumor residue, and chemotherapy status in patients with non-epithelial ovarian cancer are significant prognostic factors for DFS and 3-year survival.

Simulation-based training using a novel Surabaya hysterectomy mannequin following video demonstration to improve abdominal hysterectomy skills of obstetrics and gynecology residents during the COVID-19 pandemic in Indonesia: a pre- and post-intervention study / 보건의료교육평가

Purpose@#During the coronavirus disease 2019 (COVID-19) pandemic, the number of abdominal hysterectomy procedures decreased in Indonesia. The existing commercial abdominal hysterectomy simulation model is expensive and difficult to reuse. This study compared residents’ abdominal hysterectomy skills after simulation-based training using the Surabaya hysterectomy mannequin following a video demonstration. @*Methods@#We randomized 3rd- and 4th-year obstetrics and gynecology residents to a video-based group (group 1), a simulation-based group (group 2), and a combination group (group 3). Abdominal hysterectomy skills were compared between before and after the educational intervention. The pre- and post-tests were scored by blinded experts using the validated Objective Structured Assessment of Technical Skills (OSATS) and Global Rating Scale (GRS). @*Results@#A total of 33 residents were included in the pre- and post-tests. The OSATS and GRS mean differences after the intervention were higher in group 3 than in groups 1 and 2 (OSATS: 4.64 [95% CI, 2.90–6.37] vs. 2.55 [95% CI, 2.19–2.90] vs. 3.82 [95% CI, 2.41–5.22], P=0.047; GRS: 10.00 [95% CI, 7.01–12.99] vs. 5.18 [95% CI, 3.99–6.38] vs. 7.18 [95% CI, 6.11–8.26], P=0.006). The 3rd-year residents in group 3 had greater mean differences in OSATS and GRS scores than the 4th-year residents (OSATS: 5.67 [95% CI, 2.88–8.46]; GRS: 12.83 [95% CI, 8.61–17.05] vs. OSATS: 3.40 [95% CI, 0.83–5.97]; GRS: 5.67 [95% CI, 2.80–8.54]). @*Conclusion@#Simulation-based training using the Surabaya hysterectomy mannequin following video demonstration can be a bridge to learning about abdominal hysterectomy for residents who had less surgical experience during the COVID-19 pandemic.
