Introduction: Centralization of ovarian cancer treatment is associated with higher rates of optimal surgery and longer survival. However, preoperative diagnosis of ovarian cancer is challenging and some diagnoses are made incidentally after surgery. This study investigated the surgical and oncological outcomes of patients with incidental findings of borderline ovarian tumors or ovarian cancer who were centralized postoperatively and treated with a two-stage surgical procedure, and compared these with those of patients with adnexal masses of suspected malignancy who were offered a single-stage surgical procedure with intraoperative frozen section in a tertiary hospital. Methods: A database of 390 patients with adnexal masses and surgical treatment at the Bern University Hospital, Switzerland was retrospectively reviewed to identify patients with borderline ovarian tumors or ovarian cancer between 2010 and 2020. Results: Among 390 patients with adnexal masses, 223 were diagnosed with a borderline ovarian tumor or ovarian cancer. Compared with patients with suspected malignancy and a centralized single-stage surgical procedure, patients with an incidental postoperative malignancy diagnosis and a two-stage surgical procedure underwent more surgical interventions (1.3 vs. 2.1 p<.001) and had a longer time interval from diagnosis to initiation of chemotherapy (33.3 vs. 45.1 p=.005) and to completion of surgical cytoreduction (31.9 vs. 73.7 days, p<.001). However, there were no differences in the rates of complete cytoreduction (90.0% vs. 93.2%, p=.719), intraoperative (11.3% vs. 13.7%, p=.664) or postoperative (38.7% vs. 37.0%, p=.884) complication rates, and number of hospitalization days (11.1 vs. 12.0 days, p=.369). An incidental diagnosis of malignancy with postoperative referral was neither associated with an increased risk of recurrence (hazard ratio (HR) 0.8, 95% confidence interval (CI) 0.6-1.8, p=.839) nor death (HR 0.7, 95% CI 0.4-1.1, p=.113), and there was no difference in mean recurrence-free survival between the study subgroups. Discussion: Although patients with incidental findings of borderline ovarian tumors or ovarian cancer treated with a two-stage surgical procedure had a longer time to completion of surgical staging and initiation of chemotherapy, our results showed no negative impact on oncological outcomes.

Borderline ovarian tumors (BOTS) are rare neoplasms of intermediate aggressiveness between cystadenomas and low-grade ovarian cancers (lgOvCa), which they share some molecular resemblances with. In contrast to the most frequent and well-described high-grade ovarian carcinomas (hgOvCa), the molecular background of BOTS and lgOvCa is less thoroughly characterized. Here, we aimed to analyze genetic variants in crucial tumor suppressors and oncogenes in BOTS (with or without the BRAF V600E mutation), lgOvCa, and hgOvCa in two gene panels using next-generation sequencing. Then, we verified the existence of selected polymorphisms by Sanger sequencing. Finally, Western blot analyses were carried out to check the impact of the selected polymorphisms on the expression of the corresponding proteins. Our study contributes to the molecular characterization of ovarian neoplasms, demonstrating divergent polymorphic patterns pointing to distinct signaling pathways engaged in their development. Certain mutations seem to play an important role in BOTS without the BRAF V600E variant (KRAS) and in lgOvCa (KRAS and NRAS), but not in hgOvCa. Additionally, based on multivariable regression analyses, potential biomarkers in BOTS (PARP1) and hgOvCa (FANCI, BRCA2, TSC2, FANCF) were identified. Noteworthy, for some of the analyzed genes, such as FANCI, FANCD2, and FANCI, FANCF, TSC2, the status of BRCA1/2 and TP53, respectively, turned out to be crucial. Our results shed new light on the similarities and differences in the polymorphic patterns between ovarian tumors of diverse aggressiveness. Furthermore, the biomarkers identified herein are of potential use as predictors of the prognosis and/or response to therapy. [ABSTRACT FROM AUTHOR]

Objectives: To assess the long-term oncological safety of laparoscopic fertility-sparing surgery (FSS) in borderline ovarian tumors and the impact of laparoscopic surgical factors on recurrences. Primary outcomes were the recurrence rate and time to recurrence after laparoscopic FSS. Secondary outcomes were to evaluate the recurrence rate after a second laparoscopic surgery and to assess factors associated with the risk of relapse. Methods: This is a retrospective single-center observational study in a tertiary university-affiliated hospital. Thirty-four patients diagnosed with borderline ovarian tumors who underwent laparoscopic FSS were recruited. Patients were categorized into two groups: the adnexectomy group, including patients who underwent unilateral adnexectomy, and the cystectomy group, which included patients who underwent unilateral cystectomy, bilateral cystectomy, and unilateral adnexectomy with contralateral cystectomy. Results: Eleven relapses (32.3%) were observed during a median follow-up period of 116.1 [62.5–185.4] months. The recurrence rate was similar for patients who underwent cystectomy (6/19, 31.6%) and adnexectomy (5/15, 33.3%). Cystectomy led to a shorter time to first recurrence (36-month progression-free survival rates of 66% vs. 85%) and higher rates of capsular rupture (71.4% vs. 20%, p = 0.04) compared to adnexectomy. No deaths due to progression of disease were reported. Conclusions: Laparoscopic FSS for borderline ovarian tumors is a safe, long-term oncological option. Although the recurrence rate was similar in patients undergoing adnexectomy or cystectomy, the time to recurrence was shorter in cases treated with cystectomy. Further research is needed to identify eventual laparoscopic risk factors more strongly correlated with recurrence. [ABSTRACT FROM AUTHOR]

Abstract Background Despite the recent progress of fertility preservation technique, achievement of pregnancy in women with ovarian tumor is still challenging. Here, we report a case of OTO-IVM (ovarian tissue oocyte in-vitro maturation) resulting in a successful delivery. Case presentation The patient, a 33-year-old woman with a history of left borderline ovarian tumor (BOT) who underwent left salpingo-oophorectomy three years ago, presented with an enlarged right ovary during infertility treatment, indicating the recurrence of BOT. Because the patient disagreed with curative surgery and normal part-preservation surgery, we eventually performed OTO-IVM. A right salpingo-oophorectomy was first performed. Eight immature oocytes were immediately aspirated not only from visible follicles, but also from entire cortex for invisible follicles, of the removed ovary. In addition, IVM procedure generated six mature oocytes, and were subjected to intracytoplasmic sperm injection (ICSI). Accordingly, three embryos were obtained and cryopreserved. Three months after surgery, hormone replacement therapy was initiated, and a frozen-thawed embryo was transferred, resulting in a successful pregnancy. Although a cesarean section was performed at 36 weeks due to maternal ileus, the baby was delivered without complications. Conclusions This report indicates this treatment to be an effective approach for fertility preservation in BOT patients, especially, the importance of collecting oocytes from the entire ovarian cortex was suggested.

Abstract Objective To describe the characteristics of children and adolescents with borderline ovarian tumors (BOTs) and evaluate the efficacy and safety of fertility-sparing surgery (FSS) in these patients. Methods Patients with BOTs younger than 20 years who underwent FSS were included in this study. Results A total of 34 patients were included, with a median patient age of 17 (range, 3–19) years; 97.1% (33/34) of cases occurred after menarche. Of the patients, 82.4% had mucinous borderline tumors (MBOTs), 14.7% had serous borderline tumors (SBOTs), and 2.9% had seromucinous borderline tumor (SMBOT). The median tumor size was 20.4 (range, 8–40)cm. All patients were at International Federation of Gynecology and Obstetrics stage I and all underwent FSS: cystectomy (unilateral ovarian cystectomy, UC, 14/34, 41.2% and bilateral ovarian cystectomy, BC, 1/34, 2.9%), unilateral salpingo-oophorectomy (USO; 18/34; 52.9%), or USO + contralateral ovarian cystectomy (1/34; 2.9%). The median follow-up time was 65 (range, 10–148) months. Recurrence was experienced by 10 of the 34 patients (29.4%). One patient with SBOT experienced progression to low-grade serous carcinoma after the third relapse. Two patients had a total of four pregnancies, resulting in three live births. The recurrence rate of UC was significantly higher in MBOTs than in USO (p = 0.005). The 5-year disease-free survival rate was 67.1%, and the 5-year overall survival rate was 100%. Conclusions Fertility-sparing surgery is feasible and safe for children and adolescents with BOTs. For patients with MBOTs, USO is recommended to lower the risk of recurrence.

Women diagnosed with gynecological cancer are likely to face additional consequences beyond those common to all cancer patients leading to significant physical and psychological morbidity. Longitudinal studies addressing the prevalence of psychological distress, anxiety, or psychosexual health during follow-up in patients diagnosed with borderline ovarian tumors are lacking. This study explores this prevalence compared with controls who underwent comparable surgical treatment for benign ovarian tumors. A prospective 1:1 nonmatched case-control study was set up, registered on ClinicalTrials.gov under number NCT 04253327. Thirty early stage borderline ovarian tumor patients participated, and 30 controls were included. The study materials consisted of different questionnaires. A general one on patient’s sociodemographic and medical information. A questionnaire about anxiety and distress made up of three validated questionnaires: Hospital Anxiety and Depression Scale, Perceived Stress Scale and Body Image Scale. As last one the psychosexual health questionnaire consisted of the Female Sexual Function Index, the Female Sexual Distress Scale and two European Organisation for Research and Treatment of Cancer questionnaires. Both groups were comparable and did not differ significantly in terms of demographic characteristics. Patients with early stage borderline ovarian tumors experience a significant higher burden of mental health issues due to disease and treatment and/or are more worried about their future health. Surprisingly, both early stage borderline ovarian tumor patients and controls showed high levels of anxiety and moderate stress. Many patients in both groups experience sexual dysfunction and distress. These findings support active screening for anxiety, depression and psychosexual perturbance during postoperative follow-up to accommodate this.

Purpose: What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)? Methods: A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth. Results: In total, thirteen patients who performed 31 FP cycles were included. Of those, six patients achieved eight live births after a mean follow-up period of 79 months. Three further pregnancies are still ongoing. All pregnancies/live births were obtained without using their cryopreserved oocytes or embryos. Conclusion: Women who had FSS for BOT have favorable prospects of live offspring, even without the need to use their cryopreserved material. Fertility preservation in patients with BOT has to be considered as a tool to mitigate the risk of infertility that may arise in case of BOT recurrence requiring castrating surgery.

• BOC is worth recommending for bilateral borderline ovarian tumors and a critical factor in fertility is the preservation of maximum healthy ovarian tissue. • GnRHa increase the rate of successful clinical pregnancies.. To investigate the oncological safety and fertility outcomes of different fertility-sparing surgery procedures for bilateral borderline ovarian tumors (BOTs) and to identify the safest and most effective approach to help patients conceive with minimal risk. A retrospective study of 144 patients (≤40 years) with pathologically confirmed bilateral BOTs were included in the study.The effects of surgery type on fertility outcome and recurrence were compared. Cox regression analysis was employed to determine potential prognostic factors. Survival analysis utilized the Kaplan–Meier method. Three therapeutic modalities were applied in our study, including bilateral ovarian cystectomy (BOC; n = 29), unilateral adnexectomy + contralateral cystectomy (UAC; n = 4) and radical surgery (n = 61). Totally 33 cases (22.9 %) relapsed during the follow-up period. In 37 % of cases administered conservative surgery, relapses were diagnosed in the first 2 years. Only conservative surgery and adjuvant chemotherapy were risk factors for recurrence. Meanwhile, a pregnancy rate of 55.4 % was obtained in patients with bilateral BOTs. The pregnancy rate was slightly higher but no significant (P = 0.539) difference in patients treated with BOC (n = 17, 63 %) compared with UAC (n = 29, 55.8 %) group. GnRHa treatment significantly improved the clinical pregnancy rate in this study(P = 0.029). Satisfactory pregnancy rate can be achieved after conservative surgery in patients with bilateral BOTs. BOC is worth recommending for bilateral borderline ovarian tumors and a critical factor in fertility is the preservation of maximum healthy ovarian tissue. Patients should make a pregnancy plan in 2 years after the first surgery. GnRHa increase the rate of successful clinical pregnancies. [ABSTRACT FROM AUTHOR]

Simple Summary: Although fertility sparing surgery (FSS) may be a favorable surgical option for young women with early-stage borderline ovarian tumors (BOTs) or epithelial ovarian cancer (EOC) who wish to preserve their fertility, there still possessed risks of recurrence and disease progression during follow-up. The purpose of this retrospective article is to investigate the treatment outcomes in early-stage BOTs/EOC patients who underwent FSS. In this cohort, we found that the rate of pregnancy was higher among the married BOTs patients who had no prior live birth experience than among those who had prior live birth experience. The fertility and pregnancy outcome presented in this article may provide an important reference during pre-operative counseling. This study examined treatment outcomes, including preserved fertility, menstrual regularity, and pregnancy outcomes, in patients with stage I epithelial ovarian cancer (EOC) or borderline ovarian tumors (BOTs) who underwent fertility-sparing surgery (FSS). Patients with stage I EOC and BOTs who were aged 18–45 years and underwent FSS between 2007 and 2022 were retrospectively reviewed. Significant differences between various subgroups in terms of disease recurrence, menstrual irregularity due to the disease, and pregnancy outcomes were analyzed. A total of 71 patients with BOTs and 33 patients with EOC were included. In the BOT group, the median age was 30 (range, 19–44) years. Recurrence occurred in eight patients, with one case exhibiting a malignant transformation into mucinous EOC. Among the 35 married patients with BOTs, 20 successfully conceived, resulting in 23 live births and 3 spontaneous abortions. A higher pregnancy rate was observed in those without prior childbirth (82.4%) than in those who had prior childbirth (33.3%). In the EOC group, the median age was 34 (range, 22–42) years. Recurrence occurred in one patient. Menstrual regularity was maintained in 69.7% of the patients. Among the 14 married patients in this group, 12 achieved a total of 15 pregnancies (including 2 twin pregnancies), 16 live births, and 1 spontaneous abortion. The results of the study confirmed that FSS is a favorable surgical option for young women with early-stage BOTs or EOC who wish to preserve their fertility. However, additional investigations are needed to validate these findings. [ABSTRACT FROM AUTHOR]

Abstract Background Metastatic lung tumors rarely present with cystic formations. This is the first report of multiple cystic formations in pulmonary metastases from mucinous borderline ovarian tumors written in English. Case presentation A 41-year-old woman underwent left adnexectomy + partial omentectomy + para-aortic lymphadenectomy for a left ovarian tumor 4 years ago. The pathological finding was mucinous borderline ovarian tumor with a microinvasion. A chest computed tomography performed 3 years after surgery revealed multiple cystic lesions in both lungs. After 1-year follow-up, the cysts increased in size and wall thickness. Subsequently, she was referred to our department with multiple cystic lesions in both lungs. No laboratory findings indicated infectious diseases or autoimmune disorders that could cause cystic lesions in both lungs. Positron emission tomography showed slight accumulation in the cyst wall. Partial resection of the left lower lobe was performed to confirm the pathological diagnosis. The diagnosis was consistent with pulmonary metastases from a previous mucinous borderline ovarian tumor. Conclusions This is a rare case of lung metastases from a mucinous borderline ovarian tumor presenting with multiple lesions with cystic formation. Pulmonary cystic formations in patients with a borderline ovarian tumor should be considered as possible pulmonary metastases.

Whether infertility drug exposure increases the risk of borderline ovarian tumors (BOTs) remains controversial. The present study was conducted with a comprehensive search for studies published from January 1990 to December 2021 in the online databases Cochrane Library, PubMed, Web of Science and EMBASE. We considered the first diagnosis of a BOT as the primary outcome. The odds ratio (OR) was calculated with corresponding 95% confidence intervals (CIs) for the risk of BOTs in patients who were treated with infertility drugs. Ten studies, a total of 2,779,511 women, qualified for inclusion in this meta-analysis. The pooled OR of 1.56 (95% CI: 1.09–2.22) revealed a significant positive association between infertility drugs and an increased risk for BOTs, but for specific drugs, only CC plus Gn had statistical significance. No publication bias was detected using the Egger and Begg tests (p > 0.05). A significant difference in BOT incidence was observed among infertile women and nulliparous women who were treated with or without infertility drugs. In conclusion, the use of infertility drugs may increase the risk of BOTs, but a dose-dependent relationship was not observed between the number of assisted reproduction technology cycles and the risk of BOTs, and infertile women who successfully became pregnant might have a reduced risk.

To explore the differences in clinicopathological characteristics and prognosis between seromucinous borderline ovarian tumors (SMBOTs) and mucinous borderline ovarian tumors (MBOTs). Ninety-one patients with SMBOTs and MBOTs who underwent surgery at the Obstetrics and Gynecology Hospital of Fudan University from July 2006 to January 2015 were included. The median onset age of patients with SMBOTs (29 years, 20–77) was younger than that of patients with MBOTs (37 years, 16–71). SMBOTs were more likely to be exogenous and show bilateral ovarian involvement and had a smaller average tumor size of 10.63 cm, while MBOTs were more prone to endogenous growth and show unilateral involvement and had a larger average tumor size of 18.55 cm (p < 0.05). Compared with MBOTs, SMBOTs were characterized by the expression of Mullerian differentiation markers (p < 0.05). Recurrence occurred in 15.8% patients with SMBOT and 9.1% patients with MBOT. One case of SMBOT (2.6%) and one case of MBOT (2.3%) progressed to malignancy during follow-up, but no disease-related death was observed. Age less than 40 years was a risk factor for recurrence, while the effect of fertility-sparing surgery (FSS) on recurrence requires a larger sample size to be validated. The clinical characteristics of SMBOTs and MBOTs are similar but also quite different. High expression of Mullerian differentiation markers in SMBOT may indicate a better response to hormone therapy. Repeated FSS should be performed with caution and fully informed because of the risk of recurrence and progression to malignancy. [ABSTRACT FROM AUTHOR]

Abstract Objective To explore the association between ovulation induction drugs and ovarian cancer. Design Systematic review and meta-analysis. Setting Not applicable. Patient(s) Women without ovarian cancer who ever or never underwent ovarian induction. Intervention(s) An extensive electronic search of the following databases was performed: PubMed, EMBASE, MEDLINE, Google Scholar, Cochrane Library and CNKI, from inception until January 2022. A total of 34 studies fulfilled our inclusion criteria and were included in the final meta-analysis. The odds ratio (OR) and random-effects model were used to estimate the pooled effects. The Newcastle-Ottawa Scale was used to assess the quality of included studies. Funnel plots and Egger tests were used to assess publication bias. Main outcomes New diagnosed borderline ovarian tumor (BOT) and invasive ovarian cancer (IOC) between ovulation induction (OI) group and control (CT) group considering fertility outcome, OI cycles and specific OI drugs. Results Primarily, there was no significant difference in the incidence of IOC and BOT between the OI and CT groups. Secondly, OI treatment did not increase the risk of IOC and BOT in the multiparous women, nor did it increase the risk of IOC in the nulliparous women. However, the risk of BOT appeared to be higher in nulliparous women treated with OI treatment. Thirdly, among women exposed to OI, the risk of IOC and BOT was higher in nulliparous women than in multiparous women. Fourthly, the risk of IOC did not increase with increasing OI cycles. Lastly, exposure to specific OI drugs also did not contribute to the risk of IOC and BOT. Conclusion Overall, OI treatment did not increase the risk of IOC and BOT in most women, regardless of OI drug type and OI cycle. However, nulliparous women treated with OI showed a higher risk of ovarian cancer, necessitating their rigorous monitoring and ongoing follow-up.

Borderline ovarian tumors or atypical proliferative tumors are abnormal cells that arise from ovarian epithelium in contrast to ovarian cancers which form from stroma, the supportive tissue of ovaries. They are not invasive and tend to grow slowly. Many patients with BOTs are asymptomatic, while others have nonspecific symptoms like abdominal pain or abdominal distension. The absence of symptoms makes Borderline Ovarian Tumor hard to diagnose until it is in an advanced size or stage. Very rarely, the borderline tumor cells change into cancer cells. It usually affects patients at the reproductive age, for whom preserving the childbearing potential plays a very important role.In this report, we present the case of 58-year-old female patient who is presented to the neurosurgeon's office with complaints of lower abdominal pain. Incidentally while investigating the intervertebral discs through a lumbar MRI, an abnormal finding was present in the coronal view, where a mass was noted on the lower right adnexal region of the abdomen. The patient was referred to a gynecologist for further investigations,This case report emphasizes the high sensitivity and specificity of contrast MRI in the diagnosis of various pelvic pathologies in female patients.

Borderline ovarian tumor (BOT) accounts for 15–20% of all epithelial ovarian tumors. Concerns have arisen about the clinical and prognostic implications of BOT with exophytic growth patterns. We retrospectively reviewed all cases of BOT patients surgically treated from 2015 to 2020. Patients were divided into an endophytic pattern (with intracystic tumor growth and intact ovarian capsule) and an exophytic pattern (with tumor growth outside the ovarian capsule) group. Among the 254 patients recruited, 229 met the inclusion criteria, and of these, 169 (73.8%) belonged to the endophytic group. The endophytic group showed more commonly an early FIGO stage than the exophytic group (100.0% vs. 66.7%, p < 0.001). Furthermore, tumor cells in peritoneal washing (20.0% vs. 0.6%, p < 0.001), elevated Ca125 levels (51.7% vs. 31.4%, p = 0.003), peritoneal implants (0 vs. 18.3%, p < 0.001), and invasive peritoneal implants (0 vs. 5%, p = 0.003) were more frequently observed in the exophytic group. The survival analysis showed 15 (6.6%) total recurrences, 9 (5.3%) in the endophytic and 6 (10.0%) patients in the exophytic group (p = 0.213). At multivariable analysis, age (p = 0.001), FIGO stage (p = 0.002), fertility-sparing surgery (p = 0.001), invasive implants (p = 0.042), and tumor spillage (p = 0.031) appeared significantly associated with recurrence. Endophytic and exophytic patterns in borderline ovarian tumors show superimposable recurrence rates and disease-free survival. [ABSTRACT FROM AUTHOR]

Simple Summary: Ovarian cancer is the most lethal gynecologic cancer since it is often diagnosed at advanced stages. Current tools for diagnosis are currently insufficient and include physical examination, ultrasound and pelvic magnetic resonance imaging, as well as algorithms combining thoraco-abdomino-pelvic scans and blood markers. In this context, there is a need for new tools not only to assess the diagnosis but also to predict the response to chemotherapy and to detect recurrences. Previous studies have highlighted the potential value of non-coding RNAs (ncRNA) in tissue samples, but rarely in biofluids. In this review, we aim to summarize the existing literature on ncRNAs and ovarian tumors in biofluids. Most studies are focused on serum and blood with no data on other biofluids and with few ncRNAs investigated using qRT-PCR or microarray, which does not reflect the heterogeneity of ovarian cancers. Ovarian tumors are the most frequent adnexal mass, raising diagnostic and therapeutic issues linked to a large spectrum of tumors, with a continuum from benign to malignant. Thus far, none of the available diagnostic tools have proven efficient in deciding strategy, and no consensus exists on the best strategy between "single test", "dual testing", "sequential testing", "multiple testing options" and "no testing". In addition, there is a need for prognostic tools such as biological markers of recurrence and theragnostic tools to detect women not responding to chemotherapy in order to adapt therapies. Non-coding RNAs are classified as small or long based on their nucleotide count. Non-coding RNAs have multiple biological functions such as a role in tumorigenesis, gene regulation and genome protection. These ncRNAs emerge as new potential tools to differentiate benign from malignant tumors and to evaluate prognostic and theragnostic factors. In the specific setting of ovarian tumors, the goal of the present work is to offer an insight into the contribution of biofluid non-coding RNAs (ncRNA) expression. [ABSTRACT FROM AUTHOR]

Introduction The occurrence of two primary tumors at an interval of no more than two months is called a synchronous tumor. This also applies to female reproductive organs among which synchronous occurrence of ovarian and endometrial cancers is most frequently observed. This phenomenon is observed mainly in young women before menopause. A rare and problematic diagnostic situation is the synchronous co-occurrence of borderline ovarian carcinoma with endometrioid carcinoma of the endometrium. The diagnostic problem and treatment of this combination of cancers are presented in the following case. Case description: A 30-year-old female patient presented to the Gynecologic Oncology Department with a suspected malignant lesions of both ovaries. She underwent fertility-sparing surgery with preservation of the left ovary and uterus. Examination of the resected tissues revealed an endometrioid borderline tumor. During the next hospitalization, an excision of uterine polyps was performed, during which no neoplastic lesion of the endometrium was observed. Ultrasound examination, in which the endometrial lesion was also invisible, raised suspicion of cancer recurrence on the left ovary. The patient was scheduled for resection of the left ovary with the recurrence and hysterectomy. The histopathological examination performed confirmed the recurrence on the ovary and showed foci of G1 endometrioid carcinoma of the uterus. Conclusions Cases that meet the criteria for synchronous tumor occurrence should be considered. Appropriate diagnosis and selection of radical treatment could affect the curability of patients. Further research on rare combinations of synchronous neoplasms could be helpful in clinical practice.

Background: Borderline ovarian tumor (BOT) predominantly affects young women and is often diagnosed at an early stage. BOT accounts for 15% of all epithelial tumors. In this regard, a minimally invasive surgical approach and the ability to preserve fertility, without increasing the incidence of recurrences or worsening the prognosis, are crucial. This review aims to provide an update on the role and indications of laparoscopic surgery in BOTs. Methods: The electronic research was performed on Pubmed, Medline, and Embase. Articles published in the last 20 years (2004–2023) were included, and the following keywords were used: ‘borderline ovarian tumor’ and ‘laparoscopic surgery’, ‘borderline ovarian tumor’ and ‘minimally invasive surgery’, ‘borderline ovarian tumor’ and ‘fertility sparing’, ‘borderline ovarian tumor’ and ‘recurrence’ and ‘Borderline ovarian tumor’ and ‘relapse’. The agreement about potential relevance was reached by consensus of the researchers and according to PRISMA statement guidelines. We thoroughly reviewed all bibliographies to assess the inclusion of any further eligible studies. We excluded studies that did not align with the study’s objectives. Results: The electronic database search yielded 767 total studies. Of whom, 188 were published before 2004, 84 were case reports, and 45 were not in the English language. Of the remaining 450 studies, 148 were considered eligible for the study. We included 20 studies in this review. Conclusions: Despite the latest guidelines recommending an open approach for the treatment of BOT, the laparoscopic approach has gained popularity as a feasible and safe alternative. The use of an endo-bag, along with advanced laparoscopic skills, has made the minimally invasive approach increasingly safe, with oncological outcomes almost comparable to those of reference. Moreover, in the context of fertility-sparing surgery (FSS), laparoscopy seems to be associated with improved obstetrical outcomes, without detrimental effects on overall survival and disease-free survival. Therefore, the laparoscopic approach in the treatment of BOT appears to be a safe and effective option, especially in the case of FSS.

Simple Summary: Serous borderline ovarian tumors (SBOTs) are typically associated with an excellent prognosis. Recurrences occur in 5–10% of cases, often several years after initial diagnosis, and might display malignant transformation. Lymph node involvement can be found in up to 30% of primary SBOTs, but its prognostic value is controversial. In this review, we discuss the clinical implications of lymph node involvement in recurrent disease. Borderline ovarian tumors (BOTs) account for 10–20% of epithelial ovarian neoplasms. They are characterized by their lack of destructive stromal invasion. In comparison to invasive ovarian cancers, BOTs occur in younger patients and have better outcome. Serous borderline ovarian tumor (SBOT) represents the most common subtype of BOT. Complete surgical staging is the current standard management but fertility-sparing surgery is an option for SBOT patients who are at reproductive age. While most cases of SBOTs have an indolent course with favorable prognosis, late recurrence and malignant transformation can occur, usually in the form of low-grade serous carcinoma (LGSC). Thus, assessment of the recurrence risk is essential for the management of those patients. SBOTs can be associated with lymph node involvement (LNI) in up to 30% of patients who undergo lymph node dissection at diagnosis, and whether LNI affects prognosis is controversial. The present review suggests that recurrent SBOTs with LNI have poorer oncological outcomes and highlights the biases due to the scarcity of reports in the literature. Preventing SBOTs from recurring and becoming invasive overtime and a more profound understanding of the underlying mechanisms at play are necessary. [ABSTRACT FROM AUTHOR]

Main outcomes: New diagnosed borderline ovarian tumor (BOT) and invasive ovarian cancer (IOC) between ovulation induction (OI) group and control (CT) group considering fertility outcome, OI cycles and specific OI drugs. Results: Primarily, there was no significant difference in the incidence of IOC and BOT between the OI and CT groups. Secondly, OI treatment did not increase the risk of IOC and BOT in the multiparous women, nor did it increase the risk of IOC in the nulliparous women. However, the risk of BOT appeared to be higher in nulliparous women treated with OI treatment. Thirdly, among women exposed to OI, the risk of IOC and BOT was higher in nulliparous women than in multiparous women. Fourthly, the risk of IOC did not increase with increasing OI cycles. Lastly, exposure to specific OI drugs also did not contribute to the risk of IOC and BOT. Conclusion: Overall, OI treatment did not increase the risk of IOC and BOT in most women, regardless of OI drug type and OI cycle. However, nulliparous women treated with OI showed a higher risk of ovarian cancer, necessitating their rigorous monitoring and ongoing follow-up. [ABSTRACT FROM AUTHOR]

Simple Summary: Borderline ovarian tumors have a favorable prognosis, and with one third of tumors diagnosed in women under 40 years of age, fertility preserving approaches are necessary. However, recurrence occurs and more frequently in those with fertility preserving treatment, but there is limited evidence regarding recurrence monitoring. The aim of this retrospective chart review was to determine if regular ultrasound follow-up is effective for recurrence monitoring in those with borderline ovarian tumors. We identified 56 patients with borderline ovarian tumors at our institution, all of whom had at least yearly ultrasound follow-up. Recurrence occurred in 6 patients and ultrasound first identified recurrence in 5 patients (83.3%), prior to findings on physical exam or patient-reported symptoms. Thus, our study suggest ultrasound as an accessible, inexpensive, and safe modality of recurrence monitoring that allows early detection of tumor recurrence and thus earlier intervention and prevention of further disease progression. Borderline ovarian tumors (BOTs) are non-invasive tumors frequently diagnosed in young patients. Surgical removal of the uterus, fallopian tubes, ovaries, and omentum is considered definitive management, however fertility-sparing approach is a recognized option. Surveillance is important due to known recurrence, but there is controversy over the effectiveness of follow-up modalities. The objective is to determine the efficacy of ultrasound screening in identifying tumor recurrence. This retrospective chart review evaluated all patients consulted and/or treated surgically at our institution from January 2015 to June 2020 diagnosed with BOT. Patients were excluded if concurrently diagnosed with another gynecologic malignancy, did not have yearly ultrasound follow-up, or were lost to follow-up. This study included 56 patients, 17 of whom underwent fertility preserving surgery. The overall rate of recurrence was 10.7%; with recurrence rates of 23.5% for the fertility preserving surgery population and 5.1% for the definitive surgery population. Ultrasound first identified 5 of the 6 (83.3%) recurrences. Overall time to recurrence was 51.5 months. In conclusion, recurrences were identified on routine ultrasound screening prior to symptom onset or detection via physical exam in 83.3% of cases. While the best modality of follow-up remains controversial, this review provides evidence supporting the use of routine ultrasound follow-up for early detection of BOT recurrence.

To study the extent of hormone replacement therapy (HRT) dispensing in premenopausal women after being treated with bilateral salpingo-oophorectomy (BSOE) for ovarian cancer (OC). Nationwide population- and register-based cohort study including women 18–50 years old, registered in The Swedish Quality Register for Gynecological Cancer (SQRGC), where BSOE was performed due to epithelial (EOC) and non-epithelial ovarian cancers (NEOC) or borderline ovarian tumor (BOT) between 2008 and 2014. Data on HRT dispensing was obtained from the National Prescribed Drug Register analyzed at semi-annual intervals from surgery until end of follow-up December 2015, including a logistic regression analysis. A cohort of 664 women were identified with OC, whereas 396 women had an EOC, 61 a NEOC and 207 a BOT. At surgery 49% of the women were ≤44 years. HRT dispensed to the total cohort varied between 32% and 41% the first five years after surgery. During follow-up at first 0.5–1 year 51% of the women <40 years were dispensed HRT compared to 25% of women ≥40 years. Of women with EOC, 21% dispensed HRT at first 0.5–1 year. In the multivariable regression analysis; age <40 (OR6.17, p < 0.001) and age 40–44 (OR2.95, p < 0.001) as well as BOT histology (OR3.84, p < 0.001) were found significant variables for dispensing of HRT. A majority of premenopausal women undergoing BSOE for OC did not use HRT postoperatively. Our study shows that there is a need to address HRT use after OC treatment in young women to prevent from morbidity and a poorer quality of life. • HRT prescription pick-up is low in women with premature menopause and ovarian cancer. • <50% of premenopausal women with ovarian cancer were dispensed HRT after surgical menopause. • Young age and borderline ovarian tumors were factors that led to a significant dispensing of HRT.

Borderline or low malignant potential ovarian tumors are an intermediate entity of benign and malignant tumors whose histological alterations of the ovarian epithelial cells do not meet specific criteria for benignity or malignancy. They are tumors that generally appear during the 3rd - 4th decade of a woman's life and are diagnosed limited to the ovary in 80% of cases. In this way, the biological-oncological behavior is very good with a global survival to 10 years of 90% for initial stages and 60-70% for advanced stages. Clinically show few symptoms such as abdominal distension and oppressive pain. Imaging studies are important since it can help to consider your diagnosis, it is recommended to first perform an abdominopelvic ultrasound and then an abdominopelvic tomography. We present a 40-year-old patient case, nulliparous with a desire to preserve fertility, performing an early diagnosis and subsequent intervention with exploratory laparotomy plus left adnexectomy with a satisfactory evolution in 48 hours.

Abstract Background There are several genes associated with ovarian cancer risk. Molecular changes in borderline ovarian tumor (BOT) indicate linkage of this disease to type I ovarian tumors (low-grade ovarian carcinomas). This study determined the prevalence and association of mutations in BRCA1, BRCA2, PALB2, RAD51C, and CHEK2 with the risk of BOTs. Methods The study group consisted of 102 patients with histologically confirmed BOT and 1743 healthy controls. In addition, 167 cases with ovarian cancer G1 were analyzed. The analyses included genotyping of 21 founder and recurrent mutations localized in 5 genes (BRCA1, BRCA2, PALB2, RAD51C, and CHEK2). The risk for developing BOT and low-grade ovarian cancer, as well as the association of tested mutations with survival, was estimated. Results The CHEK2 missense mutation (c.470T>C) was associated with 2-times increased risk of BOT (OR=2.05, p=0.03), at an earlier age at diagnosis and about 10% worse rate of a 10-year survival. Mutations in BRCA1 and PALB2 were associated with a high risk of ovarian cancer G1 (OR=8.53, p=0.005 and OR=7.03, p=0.03, respectively) and were related to worse all-cause survival for BRCA1 carriers (HR=4.73, 95%CI 1.45–15.43, p=0.01). Conclusions Results suggest that CHEK2 (c.470T>C) may possibly play a role in the pathogenesis of BOT, but due to the low number of BOT patients, obtained results should be considered as preliminary. Larger more in-depth studies are required.

Univariate log rank test and Cox regression analysis were performed in the training cohort to identify prognostic factors, and a nomogram was developed to predict the recurrence rate. The model was validated by calculating the C-index and drawing the calibration curve and receiver operating curve (ROC).Conclusion: In the multivariate Cox regression analysis, practice period, past history of benign ovarian disease, past history of benign breast disease, elevated CA125 levels, elevated CA199 levels, surgical methods, greater omentum resection, FIGO stage, postoperative pregnancy, and re-operation were independently associated with recurrence-free survival (p< 0.05). The aforementioned prognostic factors were used to develop a nomogram. The nomogram demonstrated a good ability to predict the risk of recurrence (training cohort C-index: 0.866, validation cohort C-index: 0.920). The calibration curve suggested that the predicted recurrence-free survival was closely related to the actual recurrence. ROC analysis showed that the nomogram had a good discriminatory power with the area under curve between 0.776 and 0.956. The nomogram can predict the 1-, 3-, and 5-year recurrence-free survival of BOT patients undergoing fertility-preserving surgery. The predictive model can help guide surgical plans, postoperative monitoring, and prognostic evaluation of BOT patients.Keywords: borderline ovarian tumor, fertility-preserving surgery, recurrence, disease-free survival, prediction model

Objective: We aimed to evaluate adnexal masses in pregnant women who were referred to the gynecologic oncology department. Material and Methods: Data of the pregnant women referred to the gynecological oncology department between November 2016 and June 2019 with suspicion of adnexal malignancy were retrieved through the hospital's electronic medical records that included patients' demographic characteristics, gestational age, ultrasonographic, and magnetic resonance imaging findings, serum tumor markers, histopathological results. Patients with a spontaneously regressed adnexal mass, benign adnexal masses, and concurrent ectopic pregnancy were excluded. Results: The mean age of the patients was 30.9±0.87 years. The mean gestational age at diagnosis was 14.05±1.36 weeks and the mean gestational age at delivery was 35.9±1.23 weeks. The mean gestational age at diagnosis was 14.05±1.36 weeks. Twenty-five patients (59.5%) underwent laparotomy while 18 patients (40.5%) managed conservatively. The histopathological results were mucinous cystadenoma in 8 (32%) patients, mature cystic teratoma in 6 (24%) patients, borderline mucinous cystadenoma in 3 (12%) patients, borderline serous cystadenoma in 2 (8%) patients, serous cystadenoma in 2 (8%) patients, Brenner’s tumor in 2 (8%) patients, theca lutein cysts in 1 (4%) patient, and fibroma in 1 (4%) patient. None of the patients has malignant neoplasm. Conclusion: Adnexal masses at pregnancy should be referred gynecologic oncology department after the 17th week of gestation.

The patient was an unmarried nulliparous 21‐year‐old female who was referred to our hospital with an abdominal mass. Bilateral ovarian tumors with a solid component were detected and both were suspected to be ovarian cancer. Since the patient strongly wished to preserve fertility, we performed left salpingo‐oophorectomy, right cystectomy, and omentectomy. A postoperative histopathological examination revealed that the bilateral ovarian tumors were mucinous borderline tumors. The patient selected oocyte cryopreservation. Oocyte retrieval from the right ovary was performed 2 years after surgery, and six oocytes were obtained. The puncture of a small cyst revealed mucinous fluid, not normal follicular fluid; therefore, puncture fluid cytology was performed. A recurrent mucinous borderline ovarian tumor was suspected. Right salpingo‐oophorectomy was performed and a recurrent mucinous borderline ovarian tumor was diagnosed. Puncture fluid properties need to be considered when there is an opportunity for oocyte retrieval after fertility‐sparing surgery. [ABSTRACT FROM AUTHOR]

Borderline ovarian tumor is a type of tumor with generally low malignant potential. However, these tumors pose diagnostic challenges with benign and malignant epithelial ovarian tumors because the clinical symptoms are similar and investigation procedures for specific diagnosis are still debated. In addition, a small number of borderlines transform into high-grade serous ovarian carcinoma with a poor prognosis. Therefore, tools improving a better characterization of high-risk subtypes of borderline tumors to enable understanding of possible unfavorable evolution are essential for patients' management. Psammoma bodies (PBs) are microcalcifications found both in serous epithelial ovarian cancer and serous borderline tumors with possible correlation with disease progression. In this work, the chemical composition of PBs found in the tissues of borderline, high-grade and low-grade ovarian tumors was evaluated using micro-FTIR spectroscopy. Applying principal component analysis to spectral data, it was observed that among the borderline tumors analyzed (1-bl,2-bland3-bl), the PBs of3-blshowed a different chemical content from that of the PBs of the high-grade and low-grade tumors, while the PBs of1-bland2-blappeared to have similar chemical content to the PBs of high- and low-grade tumors. The discriminating wavenumbers were found to be those related to carbonate CO 3 2- (1454, 1413 cm -1 and 872 cm -1 ) and phosphate PO 4 3- (1018 cm -1 and 960 cm -1 ) present in microcalcifications. A higher ratio between peak intensities at 1413 cm -1 and 1018 cm -1 (I 1413 /I 1018 ) was observed in the PBs of3-blcompared with those of high- and low-grade ovarian carcinoma patients, which correlates with higher CO 3 2- content. On the other hand, the PBs of1-bland2-blshowed a CO 3 2- level close to that of the PBs of high- and low-grade patients. Several studies on microcalcifications in breast carcinoma have reported that increased carbonate content is related to decreased tumor aggressiveness. Therefore, case bl-3 appeared to be the less aggressive. The results obtained from FTIR analysis were in agreement with histopathological tumor classification and molecular analysis for BRAFV600E. The FTIR technique could become a reliable tool for identifying borderline low- and high-risk tumors., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

The resemblance between fallopian tube cells and serous borderline ovarian tumors (BOTs) suggests a potential origin link, with salpingitis proposed as a contributing factor in the pathogenesis of BOT. This study aimed to explore the potential association between pelvic inflammatory disease (PID) and the risk of developing BOT. A national population-based case-control study in Sweden included women with BOT between 1999 and 2020 and 10 matched controls. Data from nationwide registers were analyzed using conditional logistic regression, adjusting for age, residential district, educational level and parity. Among 4782 cases and 45,167 controls, 2.0% of cases and 1.3% of controls had a history of PID. Previous PID was associated with an increased risk of BOT overall (aOR, 1.48; 95% CI, 1.19-1.85). Significant association was observed with serous tumors (aOR, 1.76; 95% CI, 1.36-2.29), while not with mucinous tumors (aOR, 0.95; 95% CI, 0.60-1.49). A dose-response relationship between number of PID episodes and serous BOT risk was noted (P trend  < .001). This study demonstrates that PID is associated with increased risk of serous BOT, with a dose response relationship. The study highlights the potential serious implications of upper reproductive tract infections and inflammation. This underscores the need for further investigation of biological mechanisms and possible impact of PID on serous BOT development., (© 2024 The Author(s).

Whether infertility drug exposure increases the risk of borderline ovarian tumors (BOTs) remains controversial. The present study was conducted with a comprehensive search for studies published from January 1990 to December 2021 in the online databases Cochrane Library, PubMed, Web of Science and EMBASE. We considered the first diagnosis of a BOT as the primary outcome. The odds ratio (OR) was calculated with corresponding 95% confidence intervals (CIs) for the risk of BOTs in patients who were treated with infertility drugs. Ten studies, a total of 2,779,511 women, qualified for inclusion in this meta-analysis. The pooled OR of 1.56 (95% CI: 1.09–2.22) revealed a significant positive association between infertility drugs and an increased risk for BOTs, but for specific drugs, only CC plus Gn had statistical significance. No publication bias was detected using the Egger and Begg tests (p > 0.05). A significant difference in BOT incidence was observed among infertile women and nulliparous women who were treated with or without infertility drugs. In conclusion, the use of infertility drugs may increase the risk of BOTs, but a dose-dependent relationship was not observed between the number of assisted reproduction technology cycles and the risk of BOTs, and infertile women who successfully became pregnant might have a reduced risk.

Objective: The study retrospectively analyzed the clinical characteristics and prognosis of 17 cases of pregnancy complicated by borderline ovarian tumors to provide help for clinical workers. Materials and Methods: The clinicopathological data of 17 patients with ovarian borderline tumors during pregnancy at the Shengjing Hospital of China Medical University from January 2015 to June 2021 were collected and analyzed retrospectively. The average age of the patients was 31.82 years (25-45 years), the average number of pregnancies was 2.06 times (1-6 times), and the average number of births was 0.41 times (0-1 time). Results: Among the 17 patients, 4 were diagnosed in the first trimester, 2 in the second trimester, and 11 in the third trimester. Most of the first symptoms were cysts, cyst enlargement, or cyst rupture. Among them, 3 cases (1 in the first trimester and 2 in the second trimester) continued pregnancy after a conservative operation, 9 cases underwent cesarean section and a conservative operation simultaneously, and the mother and child had a good outcome. Two cases underwent conservative operations and induced abortion, and 1 case underwent an ectopic pregnancy operation at the same time. The prognosis of the patients was good without recurrence. Conclusion: Preoperative diagnosis of borderline ovarian tumors in pregnancy is delayed, and imaging and tumor markers are not specific. The coincidence rate between intraoperative frozen pathology and postoperative paraffin pathology was not high. Borderline tumors are mainly treated by surgery, and the prognosis for mothers and infants is good. [ABSTRACT FROM AUTHOR]

Unlike ovarian carcinomas, borderline ovarian tumors (BOTs) are associated with a favorable prognosis: their recurrence rate is around 5–7%, and the survival rate is more than 97% when diagnosed early. There are only a few reports of recurrence and fatal outcomes. Herein, we report a novel case of recurrent mucinous BOT, with a literature review. A 63-year-old woman presented to a local doctor with abdominal fullness. She was diagnosed as having a polycystic tumor. The lesion was suspected to be a mucinous BOT (M-BOT) on magnetic resonance imaging. Upper and lower gastrointestinal endoscopy revealed no digestive cancerous lesions, and surgery was performed. Intra-operative diagnosis confirmed the diagnosis, and total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy were performed. The final pathological diagnosis was non-invasive M-BOT (stage I c1 (T1c1N0M0)). The result of immunohistochemical staining supported the diagnosis of primary ovarian mucinous tumor.Four months after surgery, relapse occurred. Blood tests revealed an elevated carbohydrate antigen 19-9 level, and computed tomography revealed multiple liver metastases, peritoneal dissemination, left ureter infiltration, and carcinomatous peritonitis. Although the patient underwent chemotherapy, she died. This case of a very short progression-free and overall survival in stage I M-BOT indicates that some M-BOTs could result in fatal clinical outcomes despite diagnosis at an early stage. Frequent follow-up appointments after surgery could help detect relapse and increase survival in such cases. [ABSTRACT FROM AUTHOR]

To study the progression of benign ovarian lesions to mucinous borderline ovarian tumors (mBOTs); analyze the clinicopathologic features, diagnosis, and management of mBOTs in pediatric and adolescent girls; and provide a review of the literature on mBOTs in this population. Retrospective chart review of female adolescents younger than 18 years diagnosed with mBOTs between July 2017 and February 2021. Yale New Haven Hospital, New Haven, Connecticut; and Yale New Haven Health Bridgeport Hospital, Bridgeport, Connecticut. Three female patients diagnosed with mBOTs between ages 12 and 17 years. None. Clinical presentation, preoperative characteristics, surgical technique, histology, tumor stage, treatment, progression, outcome, and rate of recurrence. Three adolescent patients were identified to have mBOTs. All three patients presented with a chief complaint of abdominal pain. One of the 3 patients was premenarchal at presentation. Two of the 3 patients were initially diagnosed with a mucinous cystadenoma and had recurrences of an ovarian cyst in the same ovary within 5 and 17 months, respectively. Pathology of the recurrent cyst was consistent with mBOT. Two of the 3 patients initially underwent cystectomy, and all ultimately had a unilateral salpingo-oophorectomy. Subsequent surveillance over 2 to 4 years found no evidence of disease recurrence. mBOTs are rare in the pediatric and adolescent population and could arise from benign ovarian tumors.

Borderline ovarian tumors (BOTs) represent around 15% of all epithelial ovarian cancer. Around one third of those patients is under 40 and has not completed childbearing when the tumor is diagnosed. Cancer survivors are more and more concerned about their future fertility since a large proportion of those with BOTs are young. Whatever the tumor stage, information regarding future fertility after treatment and fertility preservation (FP) options must be delivered to all patients before treatment. A multidisciplinary team will discuss and propose personalized treatment and FP strategies. Nowadays, the FP options offered to patients with BOT are the followings: i) minimal invasive conservative surgery, ii) oocyte cryopreservation after controlled ovarian stimulation (COS) or in vitro maturation (IVM) and iii) ovarian tissue cryopreservation. Generally, the most common strategy to preserve future fertility is represented by minimal invasive conservative surgery. However, with the remarkable success and evolution of assisted reproductive technologies (ART) – notably progress and efficiency in COS and oocyte vitrification – have led to offer another potential approach for FP consisting in oocyte cryopreservation. Several COS protocols, such as random start or dual stimulation associating tamoxifen or aromatase inhibitors with gonadotropins provide similar results when compared to standard protocols while providing safety by minimizing the risk of high estrogen exposure. When COS is contraindicated, oocyte cryopreservation can still be possible throw IVM. Even though, oocyte competence after IVM is lower than that obtained after COS. A less used approach is cryopreservation of ovarian tissue, consisting in freezing ovarian cortex fragments for a future thawing and graft. Some concerns and limitations regard the ovarian cortex graft and the risk of reintroducing malignant cells once performed. Nonetheless, the latter it is the only option in prepubertal patients.

Abstract We report a case of ultrasound-guided ex vivo oocyte retrieval for fertility preservation in a woman with bilateral borderline ovarian tumor, for whom conventional transvaginal oocyte retrieval was deemed unsafe because of the increased risk of malignant cell spillage. Ovarian stimulation with gonadotropins was performed. Surgery was scheduled according to the ovarian response to exogenous gonadotropic stimulation; oophorectomized specimens were obtained by laparoscopy, and oocyte retrieval was performed ~ 37 hours after the ovulatory trigger. The sum of 20 ovarian follicles were aspirated, and 16 oocytes were obtained.We performed vitrification of 12 metaphase II oocytes and 3 oocytes matured in vitro. Our result emphasizes the viability of ex vivo mature oocyte retrieval after controlled ovarian stimulation for those with high risk of malignant dissemination by conventional approach.

Objective: To investigate the impact of cystectomy for borderline ovarian tumor (BOT) on tumor recurrence compared with salpingo-oophorectomy using inverse probability of treatment weighting (IPTW). Methods: A central pathologic review and a search of the medical records from 14 collaborating institutions from 1986 to 2017 identified 4708 women with a malignant ovarian neoplasm. Data for young women with Stage I BOT were extracted. To compare recurrence-free survival between the surgery groups, Cox regression analyses and the IPTW-adjusted Kaplan-Meier method were employed. Results: During a median follow-up of 62.0 (1.2-270.4) months, 10 of the 285 patients identified (3.5%) developed recurrence. In multivariate analysis, the practice of cystectomy was not a significant prognostic indicator of recurrence-free survival (hazard ratio [95% confidence interval] 1.276 [0.150-10.864]; P = 0.823). In the IPTW-adjusted cohort, the 5-year recurrence-free survival rates were 95.8% and 96.0% in patients receiving cystectomy and salpingo-oophorectomy, respectively (P = 0.378). Conclusion: If patients are selected appropriately, cystectomy in itself may not increase tumor recurrence in young women with early-stage BOT. A large-scale prospective clinical study is necessary to validate this finding. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the prediction efficacy of malignant transformation of ovarian endometrioma (OE) using the Copenhagen Index (CPH-I), the risk of ovarian malignancy algorithm (ROMA), and the R2 predictive index. This retrospective study was conducted at the Department of Gynecology, Nara Medical University Hospital, from January 2008 to July 2021. A total of 171 patients were included in the study. In the current study, cases were divided into three cohorts: pre-menopausal, post-menopausal, and a combined cohort. Patients with benign ovarian tumor mainly received laparoscopic surgery, and patients with suspected malignant tumors underwent laparotomy. Information from a review chart of the patients' medical records was collected. In the combined cohort, a multivariate analysis confirmed that the ROMA index, the R2 predictive index, and tumor laterality were extracted as independent factors for predicting malignant tumors (hazard ratio (HR): 222.14, 95% confidence interval (CI): 22.27–2215.50, p < 0.001; HR: 9.80, 95% CI: 2.90–33.13, p < 0.001; HR: 0.15, 95% CI: 0.03–0.75, p = 0.021, respectively). In the pre-menopausal cohort, a multivariate analysis confirmed that the CPH index and the R2 predictive index were extracted as independent factors for predicting malignant tumors (HR: 6.45, 95% CI: 1.47–28.22, p = 0.013; HR: 31.19, 95% CI: 8.48–114.74, p < 0.001, respectively). Moreover, the R2 predictive index was only extracted as an independent factor for predicting borderline tumors (HR: 45.00, 95% CI: 7.43–272.52, p < 0.001) in the combined cohort. In pre-menopausal cases or borderline cases, the R2 predictive index is useful; while, in post-menopausal cases, the ROMA index is better than the other indexes. [ABSTRACT FROM AUTHOR]

The risk for developing BOT and low-grade ovarian cancer, as well as the association of tested mutations with survival, was estimated. Results: The CHEK2 missense mutation (c.470T>C) was associated with 2-times increased risk of BOT (OR=2.05, p=0.03), at an earlier age at diagnosis and about 10% worse rate of a 10-year survival. Mutations in BRCA1 and PALB2 were associated with a high risk of ovarian cancer G1 (OR=8.53, p=0.005 and OR=7.03, p=0.03, respectively) and were related to worse all-cause survival for BRCA1 carriers (HR=4.73, 95%CI 1.45–15.43, p=0.01). Conclusions: Results suggest that CHEK2 (c.470T>C) may possibly play a role in the pathogenesis of BOT, but due to the low number of BOT patients, obtained results should be considered as preliminary. Larger more in-depth studies are required. [ABSTRACT FROM AUTHOR]

Objective: Epithelial borderline ovarian tumor (BOT) frequently occurs in young women. Because progression‐free survival, overall survival, and reproductive function are important outcomes, BOT is often treated by fertility‐sparing surgery (FSS). We conducted a Japan‐wide study to understand post‐FSS prognosis in relation to clinical characteristics and types of FSS performed. Methods: We analyzed clinical and outcome data pertaining to 531 adolescent and young adult (AYA) patients (aged 15–39 years) who underwent FSS for BOT between 2009 and 2013. Results: Median (range) age was 30 (15–39) years, and median observation time was 70 (2–120) months. The disease was of FIGO stage I in 492 (93%) patients. Histopathologically, tumors were of the mucinous (n = 372, 70%), serous (n = 120, 23%), seromucinous (n = 23, 4%), and other (n = 16, 3%) types. Five‐year overall survival was 99.5% among patients with stage I and 100% among those with stage II–IV. Five‐year progression‐free survival was 96.7% and 69.3%, respectively. Multivariate analysis in cases of stage I showed a positive peritoneal cytology to be a significant risk factor for recurrence (HR, 5.199; p = 0.0188). The post‐FSS pregnancy rate was relatively low for patients aged ≥30 years (OR, 0.868; 95% CI, 1.16–3.00; p = 0.0090). Conclusion: Post‐FFS outcomes in terms of overall and progression‐free survival are favorable, especially for AYA patients with stage I BOT. However, the relapse rate is high for patients with FIGO stage II–IV and for those with stage I but a positive peritoneal cytology. A long‐term prospective observation is needed before reproductive outcomes can be fully established. [ABSTRACT FROM AUTHOR]

Borderline ovarian tumor is a tumor with pathomorphological characteristics, biological behavior and prognosis between benign and malignant tumors. Preoperative diagnosis of ovarian cancer is usually based on imaging and tumor markers. Because of the early diagnosis and good prognosis of borderline ovarian tumors, fertility preserving surgery can be selected for patients with borderline ovarian tumors who have not completed fertility. Compared with radical surgery, fertility preserving surgery has a higher recurrence rate, but most of them are not malignant, which will not affect the overall survival rate, and the postoperative fertility rate is also very good. Patients with borderline ovarian tumors, especially those with BOT stage II or above, should get pregnant as soon as possible and be followed up closely for a long time. [ABSTRACT FROM AUTHOR]

Multivariate logistic regression was used to identify all independent risk factors associated with LNI; these were then incorporated into the prediction model.Results: In total, we included 248 patients with BOT who were undergoing lymphadenectomy. These were divided into a training cohort (n=174) and a validation cohort (n=74). When considering histopathological data, 16 and 5 patients were identified to have LNI in the training and validation cohorts, respectively. Overall, 13.5% (21/156) patients with serous BOT had LNI while 0% (0/92) patients with non-serous BOT had LNI. We identified several predictors of LNI: the largest tumor being ≥ 12.2cm in diameter, the presence of lesions on the ovarian surface, and the presence of pelvic or abdominal lesions. We created a prediction model and nomogram that incorporated these three risk factors for serous BOT. The model achieved good discriminatory abilities of 0.951 and 0.848 when predicting LNI in the training and validation cohorts, respectively. The LNI-predicting nomogram had an area under curve (AUC) of 0.951 and generated well-fitted calibration curves.Conclusion: Non-serous BOT may not require lymphadenectomy as part of surgical staging. The individual risk of LNI in patients with serous BOT can be accurately estimated using our prediction model and nomogram. The use of LNI criteria provides a practical way to support the clinician in making an optimal decision relating to surgical scope for patients with BOT.Keywords: lymph node involvement, borderline ovarian tumor, lymphadenectomy, prediction model, nomogram

Women diagnosed with gynecological cancer are likely to face additional consequences beyond those common to all cancer patients leading to significant physical and psychological morbidity. Longitudinal studies addressing the prevalence of psychological distress, anxiety, or psychosexual health during follow-up in patients diagnosed with borderline ovarian tumors are lacking. This study explores this prevalence compared with controls who underwent comparable surgical treatment for benign ovarian tumors. A prospective 1:1 nonmatched case-control study was set up, registered on ClinicalTrials.gov under number NCT04253327. Thirty early stage borderline ovarian tumor patients participated, and 30 controls were included. The study materials consisted of different questionnaires. A general one on patient's sociodemographic and medical information. A questionnaire about anxiety and distress made up of three validated questionnaires: Hospital Anxiety and Depression Scale, Perceived Stress Scale and Body Image Scale. As last one the psychosexual health questionnaire consisted of the Female Sexual Function Index, the Female Sexual Distress Scale and two European Organisation for Research and Treatment of Cancer questionnaires. Both groups were comparable and did not differ significantly in terms of demographic characteristics. Patients with early stage borderline ovarian tumors experience a significant higher burden of mental health issues due to disease and treatment and/or are more worried about their future health. Surprisingly, both early stage borderline ovarian tumor patients and controls showed high levels of anxiety and moderate stress. Many patients in both groups experience sexual dysfunction and distress. These findings support active screening for anxiety, depression and psychosexual perturbance during postoperative follow-up to accommodate this.
