Revista colombiana de obstetricia y ginecologia · Jun 2024 · expert consensus / practice guideline based on literature review
This paper is an expert consensus, not a clinical study of a single drug. Eleven specialists reviewed the literature and issued recommendations for managing advanced or metastatic high-grade epithelial ovarian cancer, including surgery, chemotherapy, genetic testing, bevacizumab, and PARP inhibitors. It does not report new patient outcomes from a trial. The document mainly summarizes what the panel suggested based on existing guidelines and evidence.
Studied with: platinum-based chemotherapy, bevacizumab, paclitaxel, carboplatin.
Key findings
- The panel suggested primary cytoreductive surgery as the initial approach when complete resection is feasible.
- Neoadjuvant chemotherapy followed by interval surgery was suggested when complete cytoreduction is unlikely or the patient has poor functional status/comorbidities.
- Bevacizumab was suggested with platinum-based chemotherapy for high-risk disease, with maintenance only if it was part of first-line therapy.
- PARP inhibitors (olaparib, niraparib, rucaparib) were suggested as maintenance in selected BRCA/HRD-defined groups.
- For platinum-resistant relapse, sequential non-platinum single-agent chemotherapy and best supportive care for poor performance status were suggested.
Limitations: This is a consensus statement/practice guideline, not an original comparative trial.; No new efficacy or safety data are reported in the abstract.; Recommendations are based on literature review and expert agreement, so they are subject to guideline-selection and expert-opinion bias.; The abstract does not provide patient-level outcomes, follow-up, or effect estimates.; Several recommendations are conditional/suggested rather than based on direct evidence from this paper..
Provides management recommendations for advanced/metastatic epithelial ovarian cancer, including several anticancer agents and maintenance strategies.

Relacorilantovarian cancerovarian epithelial carcinomaprimary peritoneal cancerfallopian tube cancerovarian carcinosarcoma This phase II study tested relacorilant added to nab-paclitaxel in women with recurrent platinum-resistant or refractory ovarian and related cancers. The intermittent relacorilant schedule improved progression-free survival and duration of response compared with nab-paclitaxel alone, while overall response rate was similar across groups. Side effects were broadly comparable between arms, and the study did not meet its prespecified statistical threshold after multiplicity adjustment.
Reported effects: PFS HR 0.66, p P = .038, n=178 · DOR HR 0.36, p P = .006, n=178 · +1 more
Studied with: nab-paclitaxel.
Key findings
- Intermittent relacorilant plus nab-paclitaxel improved PFS versus nab-paclitaxel monotherapy (HR 0.66; P = .038).
- Intermittent relacorilant plus nab-paclitaxel improved DOR versus nab-paclitaxel monotherapy (HR 0.36; P = .006).
- ORR was similar across arms.
- At the preplanned OS analysis, the OS HR was 0.67 with P = .066 for the intermittent arm versus nab-paclitaxel monotherapy.
- Continuous relacorilant plus nab-paclitaxel showed numerically improved median PFS but no significant improvement over monotherapy.
- Adverse events were comparable across study arms; common grade ≥3 events included neutropenia, anemia, peripheral neuropathy, and fatigue/asthenia.
Limitations: Phase II study with relatively small sample size.; Open-label design.; Primary end point did not reach statistical significance after protocol-prespecified Hochberg step-up multiplicity adjustment.; Median follow-up was limited for PFS and OS analyses.; Safety and efficacy were compared against nab-paclitaxel monotherapy, but the abstract does not provide detailed absolute event rates..

ovarian epithelial carcinomaovarian epithelial masses
This cross-sectional study compared three blood markers—HE4, ROMA, and CA-125—in 203 people with ovarian epithelial masses before surgery. The markers were higher in malignant tumors than in benign or borderline tumors. The study also reported that CA-125 had the highest sensitivity overall, while HE4 and ROMA had higher specificity in some groups.
Reported effect: P value for higher marker levels in malignant tumors, p < 0.001, n=203
Key findings
- All three markers were significantly higher in malignant tumors than in benign or borderline tumors (P < 0.001 for all).
- CA-125 had the highest sensitivity overall in pre- and post-menopausal patients (90.7%).
- HE4 and ROMA had higher specificity than CA-125 overall (98.1% and 97.5% vs 86.9%).
- In postmenopausal patients, HE4 and ROMA sensitivities were both 90.5%, while CA-125 specificity and sensitivity were the highest (95.2% and 100%).
- In premenopausal patients, ROMA sensitivity was 90.9% and HE4 specificity was 100%.
Limitations: Cross-sectional design limits causal inference.; Single study with a modest sample size.; Diagnostic accuracy was assessed against pathology, not patient outcomes.; The abstract does not provide confidence intervals for the reported sensitivities/specificities.; The study evaluates biomarkers for prediction/diagnosis rather than effects on cancer growth or survival..

ovarian endometrioid carcinomaovarian epithelial carcinomaovarian neoplasmssex cord-gonadal stromal tumours
This narrative review summarizes the wide range of morphologies and immunophenotypes seen in ovarian endometrioid carcinoma, including metaplastic changes, spindle cell/corded and hyalinised features, and sex cord-like formations. It notes that these tumours can undergo transdifferentiation (for example an association with a somatically derived yolk sac tumour) and that aberrant immunohistochemical profiles may complicate distinction from other ovarian tumours. The review also discusses genomic characteristics and the recent incorporation of seromucinous carcinoma into the endometrioid carcinoma category.
Key findings
- Ovarian endometrioid carcinoma (EC) comprises approximately 10-12% of ovarian epithelial malignancies (stated in abstract).
- EC displays protean and diverse morphologies, including metaplastic changes, spindle cell differentiation/corded and hyalinised features, and sex cord-like formations.
- Ovarian ECs show propensity for transdifferentiation; one example discussed is an association with a somatically derived yolk sac tumour.
- Immunohistochemistry is useful for diagnosing EC and distinguishing it from other ovarian epithelial malignancies, metastases, and sex cord-stromal tumours, but ECs may exhibit aberrant immunophenotypes that increase diagnostic uncertainty.
- The review discusses the genomic characteristics of these tumours and the recent incorporation of seromucinous carcinoma into the EC category.
Limitations: Review article—no new primary data or experiments reported in this paper.; Narrative review (not stated as systematic); potential for selection or reporting bias in which studies/features are emphasized.; Findings are descriptive and focused on diagnostic morphology/immunophenotype; no quantitative synthesis or prospective validation presented..

low-grade serous ovarian carcinomaovarian epithelial carcinoma
This retrospective, registry-based study examined stage at diagnosis, primary surgical treatment (primary vs interval debulking) and 5-year relative survival in 855 patients with low-grade serous ovarian carcinoma in the Netherlands (2000–2019). Over time tumors were more often stage III–IV and interval debulking was used more frequently; overall 5-year relative survival was 61%. Patients who underwent primary debulking surgery had higher 5-year survival than those who underwent interval debulking (60% vs 34%), and absence of macroscopic residual disease after surgery was associated with the best survival.
Reported effects: Stage III (trend), p <0.001 · Stage IV (trend), p <0.001 · +10 more
Key findings
- LGSC was increasingly diagnosed as stage III (39.9%-59.0%) and IV (5.7%-14.4%) and less often as stage I (34.6%-13.5%; p < 0.001).
- Primary debulking surgery was the most common strategy (76.2%), but use of interval debulking increased from 10.6% to 31.1% (p < 0.001).
- Following primary surgery >1 cm residual disease occurred in 15/252 patients (6%) compared with 17/95 patients (17.9%) after interval surgery.
- Full cohort 5-year relative survival was 61%.
- Five-year survival after primary debulking surgery was 60% versus 34% after interval debulking surgery.
- After primary debulking surgery, 5-year survival was 73% with no macroscopic residual disease, 47% with ≤1 cm residual disease and 22% with >1 cm residual disease.
- After interval debulking surgery, 5-year survival was 51% with no macroscopic residual disease versus 24% with >1 cm residual disease.
- Except for FIGO stage II (85%-92%), survival did not change significantly over time.
Limitations: Retrospective, observational design using registry data (cannot establish causality).; Potential selection bias and confounding in choice of primary versus interval debulking (non-randomized comparison).; Single-country (Netherlands) data may limit generalizability to other settings.; Abstract does not report details on systemic therapies, performance status, or reasons for choosing surgical strategy (potential unmeasured confounders)..

ovarian epithelial carcinomaovarian neoplasmshigh grade serous ovarian carcinomaendometrioid ovarian carcinomaclear cell ovarian carcinomamucinous ovarian carcinomalow grade serous ovarian carcinoma
This review discusses how ovarian epithelial cancers differ by histotype in their molecular features and clinical behavior. It notes that knowledge of high-grade serous ovarian cancer has led to advances such as PARP inhibitor use, but that these agents are not suitable for all patients, especially many with rare histotypes. The paper emphasizes that more molecular profiling is needed to find additional targeted strategies for these cancers.
Key findings
- Ovarian carcinoma comprises multiple distinct histotypes with different developmental origins, clinical behavior, and molecular profiles.
- Knowledge of driver events in high-grade serous ovarian cancer has led to major advances in treatments, including PARP inhibitor use.
- PARP inhibitors are not suitable for all patients, notably many with rare ovarian cancer histotypes.
- Genomic characterization in endometrioid, clear cell, mucinous, and low-grade serous ovarian cancer has expanded understanding of mutational events.
- Substantial knowledge gaps remain, and the review calls for histotype-specific targeted therapeutic strategies.
Limitations: Review article; no original experimental or clinical data.; No quantitative outcomes reported.; Does not evaluate a specific intervention in a controlled study.; Conclusions are based on synthesis of prior literature..
Provides a review of molecular characteristics and clinical behavior of ovarian epithelial cancers, with mention of PARP inhibitors as part of the broader treatment landscape.

ovarian epithelial carcinoma (OEC)
The study measured miR-130a-3p expression by qRT-PCR in ovarian epithelial carcinoma (OEC) tissues and cell lines, analyzed associations with clinicopathologic features and overall survival, and performed in vitro functional assays. miR-130a-3p expression was reported as lower in OEC samples compared with adjacent normal tissue, low expression associated with worse survival/advanced clinicopathologic features, and overexpression in cell lines reduced proliferation and affected the cell cycle. The authors propose miR-130a-3p as a prognostic biomarker and potential therapeutic target, but clinical validation is not provided.
Key findings
- miR-130a-3p expression was assessed by qRT-PCR in OEC tissues and cell lines.
- Expression of miR-130a-3p was found to be lower in 7 OEC samples compared with adjacent normal tissues.
- Low miR-130a-3p expression was associated with lower overall survival and with FIGO stage and lymph node metastasis (clinicopathologic features).
- Multivariate Cox analysis identified miR-130a-3p as an independent candidate for predicting prognosis in OEC patients.
- Over-expression of miR-130a-3p in OEC cell lines inhibited cell proliferation and altered the cell cycle in vitro.
Limitations: Abstract does not report total cohort/sample size (only notes lower expression in 7 OEC samples), so the patient sample size and statistical power are unclear.; Prognostic associations are observational and may be subject to confounding; causality is not established.; Functional experiments were performed in vitro (cell lines) with no in vivo or clinical intervention data presented.; Abstract lacks detailed statistical values (HRs, CIs, p-values) and methodological details in the text provided..

ovarian cancerovarian epithelial carcinomahigh-grade serous carcinomaendometriosis-associated carcinoma
This narrative review summarizes current understanding of the origins and precursor lesions of ovarian epithelial carcinomas (especially high-grade serous and endometriosis-associated carcinomas) and implications for surgical prevention. It reviews epidemiologic evidence on endometriosis excision, tubal procedures, and bilateral salpingo-oophorectomy and discusses short- and long-term consequences for women's health and quality of life. The authors provide recommendations for women with high-risk genetic mutations and average-risk women and highlight remaining gaps and ongoing research needed to define optimal surgical approaches.
Key findings
- Effective screening for ovarian cancer is lacking, and surgical removal of at-risk tissue is described as the most successful strategy to decrease risk of cancer development.
- Optimal timing of surgery, which tissues to remove, and appropriate patient selection for preventive procedures are poorly understood.
- The review discusses origins and precursor lesions of ovarian epithelial carcinomas, focusing on high-grade serous and endometriosis-associated carcinomas.
- The authors summarize epidemiologic evidence on surgical prevention strategies including endometriosis excision, tubal procedures, and bilateral salpingo-oophorectomy and consider short- and long-term consequences on women's health and quality of life.
- The review concludes with recommendations for women with high-risk genetic mutations and for average-risk women and notes ongoing research to clarify optimal approaches that balance risk reduction with quality of life.
Limitations: This is a narrative review and does not present new primary data.; The epidemiologic evidence reviewed is likely observational in nature (as stated) and subject to limitations of such studies.; The abstract states important knowledge gaps remain (optimal timing, tissues to remove, and patient selection), limiting definitive guidance.; Potential short- and long-term consequences for quality of life mean risk-reduction benefits must be balanced against harms; the review does not resolve these trade-offs..

The authors performed a systematic review and meta-analysis of 11 studies (1058 patients) to assess whether MMP-2 expression predicts prognosis in epithelial ovarian cancer. They found that MMP-2 overexpression in tumor cells was associated with worse prognosis (pooled HR 1.42, 95% CI 1.14–1.70), while stromal MMP-2 overexpression was not clearly associated (pooled HR 1.09, 95% CI 0.32–1.86). The authors note heterogeneity in the stromal analysis and conclude additional high-quality studies are needed to confirm the finding.
Reported effects: Pooled HR (stromal MMP-2 overexpression) 1.09 [0.32–1.86], p=0.006 · Pooled HR (tumor-cell MMP-2 overexpression) 1.42 [1.14–1.7], p=0
Key findings
- 11 studies comprising 1058 patients were included in the meta-analysis.
- Pooled hazard ratio (HR) for stromal MMP-2 overexpression: 1.09 (95% CI 0.32-1.86, p = 0.006) with significant heterogeneity between studies (I2 = 53.1%, p = 0.074).
- Pooled HR for tumor-cell MMP-2 overexpression: 1.42 (95% CI 1.14-1.70, p = 0.000) with no significant heterogeneity between studies (I2 = 43.4%, p = 0.078).
- Sensitivity analyses were reported as stable.
- Conclusion stated: MMP-2 overexpression in tumor cells rather than stroma was significantly associated with poor prognosis in patients with epithelial ovarian cancer, but further high-quality studies are needed.
Limitations: Meta-analysis includes only 11 studies and 1058 patients (limited study count).; Significant heterogeneity reported for the stromal MMP-2 analysis (I2 = 53.1%).; The authors state results require confirmation with additional high-quality studies (possible limitations in included study quality or consistency)..

This study looked at microRNA-490-3P in ovarian epithelial carcinoma using cell experiments and in vivo studies. The researchers found that increasing miR-490-3P reduced cancer cell growth, migration, and invasion, and increased cell-cycle arrest and apoptosis. They also reported that miR-490-3P directly targeted CDK1 and reduced tumor development in vivo.
Key findings
- miR-490-3P expression was lower in ovarian carcinoma and metastatic ovarian carcinoma than in benign or primary ovarian carcinoma samples.
- MiR-490-3P overexpression promoted G1/S or G2/M arrest and apoptosis and reduced proliferation, migration, and invasion in ovarian cancer cells.
- Dual-luciferase reporter assay indicated miR-490-3P directly targeted CDK1.
- In vivo studies showed miR-490-3P transfection suppressed tumor development and altered CDK1, Bcl-xL, MMP2/9, and P53 expression.
Limitations: Preclinical study; findings are based on cell experiments and in vivo models, not human treatment.; The abstract does not provide sample size, animal species, dose, or follow-up duration.; No quantitative effect sizes or statistical values are reported in the abstract for the main functional outcomes..

This study looked at REG4 in ovarian epithelial carcinoma using SKOV3 cells and ovarian tissue samples. In cells, adding REG4 or making cells overexpress REG4 reduced apoptosis and increased proliferation, migration, invasion, and G2/S cell-cycle progression. In patient tissues, REG4 was more highly expressed in tumor samples than in normal ovarian tissue, and higher REG4 expression was linked with worse survival outcomes.
Key findings
- REG4 overexpression and recombinant REG4 inhibited apoptosis in SKOV3 cells.
- REG4 increased proliferation, migration, invasion, and G2/S progression in SKOV3 cells.
- Wnt5a, p70s6k, survivin, and VEGF increased, while Bax decreased with REG4 overexpression.
- REG4 mRNA and protein were higher in ovarian tumor tissues than in normal ovarian tissue.
- Higher REG4 expression was associated with poorer cumulative and relapse-free survival.
Limitations: Primarily cell-line and tissue-expression study; no therapeutic intervention in patients.; Observational survival association cannot establish causality.; Abstract does not report sample sizes, effect sizes, or detailed statistical estimates.; Findings are based on one ovarian cancer cell line (SKOV3) and may not generalize to all ovarian cancers..
REG4 was studied as a biomarker and functional regulator in ovarian cancer, not as a repurposed drug or natural compound.
