Seromucinous borderline tumors (SMBT) are papillary neoplasms without invasive capabilities. Originally categorized as ovarian tumors, SMBT, being an endometriosis‐related tumor, can manifest beyond the ovaries. To date, only four cases of extraovarian SMBT have been documented in literature. In this report, we present our experience with the first case of SMBT in the uterine cervix, which exhibited highly elevated CA19‐9 levels. The patient, initially clinically diagnosed with cervical cancer, underwent treatment with radical hysterectomy and was later pathologically diagnosed with SMBT of the uterine cervix. While extraovarian SMBT, especially in the uterine cervix, is extremely rare, this condition should be considered in patients with cervical masses lacking pathological evidence of malignant disease but displaying elevated CA19‐9 levels.

Simple Summary: This systematic review was conducted using four public electronic databases (PubMed, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials) from the date of inception to 31 May 2023, and 10 original articles with information regarding neoadjuvant chemotherapy (NACT) for malignant ovarian germ cell tumors (MOGCT) were identified. The results of the meta-analysis showed that NACT was used in approximately 40% of advanced MOGCT cases, with a response rate of 95.8%. The uterine preservation rate was approximately 70%, and the cumulative resumed menstruation rate was 100% (n = 30). Four comparator studies evaluating NACT versus primary debulking surgery between the groups showed similar overall survival, disease-free survival, recurrence rate, and adverse event rate (grade 3–4) from chemotherapy. Although available data are limited and level I evidence is lacking, we believe that NACT may be feasible for advanced MOGCT. Further studies are required to confirm this study's results. Randomized clinical trials assessing the efficacy of neoadjuvant chemotherapy (NACT) for advanced epithelial ovarian cancer have predominantly included women with high-grade serous carcinomas. The response rate and oncological outcomes of NACT for malignant ovarian germ cell tumors (MOGCT) are poorly understood. This study aimed to examine the effects of NACT on women with MOGCT by conducting a systematic review of four public search engines. Fifteen studies were identified, and a further descriptive analysis was performed for 10 original articles. In those studies, most women were treated with a bleomycin, etoposide, and cisplatin regimen, and one to three cycles were used in most studies. Four studies comparing NACT and primary debulking surgery showed similar complete response rates (n = 2; pooled odds ratio [OR] 0.90, 95% confidence interval [CI] 0.15–5.27), comparable overall survival (n = 3; 87.0–100% versus 70.0–100%), disease-free survival (n = 3; 87.0–100% versus 70.0–100%), recurrence rate (n = 1; OR 3.50, 95%CI 0.38–32.50), and adverse events rate from chemotherapy between the groups. In conclusion, NACT may be considered for the management of MOGCT; however, possible candidates for NACT use and an ideal number of NACT cycles remain unknown. Further studies are warranted to validate the efficacy of NACT in advanced MOGCT patients. [ABSTRACT FROM AUTHOR]

Simple Summary: To investigate the efficacy of minimally invasive surgery (MIS) in the treatment of uterine-confined and node-negative cervical cancer in Japan, we conducted a population-based study using Osaka Cancer Registry data ranging between 2011 and 2018. A total of 2279 patients who underwent surgical treatment for uterine-confined and node-negative cervical cancer were identified. The patients were classified into groups according to surgery type (open and MIS groups) and year of diagnosis (2011–2014 and 2015–2018), and their oncologic outcomes were compared between the MIS and open groups. In the analyses including all patients, i.e., patients diagnosed in 2011–2014 and those diagnosed in 2015–2018, there were no differences in overall survival between the MIS and open groups. Our population-based cohort study provides epidemiological evidence that MIS does not compromise survival outcomes when compared with conventional open surgery in Japanese patients with FIGO 2018 stage I cervical cancer. We aimed to compare the oncological outcomes between Japanese women with uterine-confined and node-negative cervical cancer who underwent open surgery and those who underwent minimally invasive surgery (MIS). A population-based retrospective cohort study was conducted using data from the Osaka Cancer Registry that ranged from 2011 to 2018. A total of 2279 patients who underwent surgical treatment for uterine-confined and node-negative cervical cancer were identified. The patients were classified into groups according to surgery type (open and MIS groups) and year of diagnosis (group one, 2011–2014; group two, 2015–2018). The oncologic outcomes were compared between the MIS and open groups. When the MIS group (n = 225) was compared with open group (n = 2054), overall, there was no significant between-group difference in terms of overall survival. Based on Kaplan–Meier estimates, the probability of overall survival at four years was 99.5% in the MIS group and 97.2% in the open group (p = 0.1110). When examined according to the year of diagnosis, there were no significant between-group differences in the overall survival in both groups one and two. In this population-based cohort study, MIS did not compromise survival outcomes when compared with conventional open surgery in Japanese patients with uterine-confined and node-negative (FIGO 2018 stage I) cervical cancer.
