RESUMEN
Ovarian cancer is the second most common cause of gynecologic cancer death in women around the world. The outcomes are complicated, because the disease is often diagnosed late and composed of several subtypes with distinct biological and molecular properties (even within the same histological subtype), and there is inconsistency in availability of and access to treatment. Upfront treatment largely relies on debulking surgery to no residual disease and platinum-based chemotherapy, with the addition of antiangiogenic agents in patients who have suboptimally debulked and stage IV disease. Major improvement in maintenance therapy has been seen by incorporating inhibitors against poly (ADP-ribose) polymerase (PARP) molecules involved in the DNA damage-repair process, which have been approved in a recurrent setting and recently in a first-line setting among women with BRCA1/BRCA2 mutations. In recognizing the challenges facing the treatment of ovarian cancer, current investigations are enlaced with deep molecular and cellular profiling. To improve survival in this aggressive disease, access to appropriate evidence-based care is requisite. In concert, realizing individualized precision medicine will require prioritizing clinical trials of innovative treatments and refining predictive biomarkers that will enable selection of patients who would benefit from chemotherapy, targeted agents, or immunotherapy. Together, a coordinated and structured approach will accelerate significant clinical and academic advancements in ovarian cancer and meaningfully change the paradigm of care.

BACKGROUND: Cyclic nucleotides play critical roles in cardiovascular biology and disease. PDE10A (phosphodiesterase 10A) is able to hydrolyze both cAMP and cGMP. PDE10A expression is induced in various human tumor cell lines, and PDE10A inhibition suppresses tumor cell growth. Chemotherapy drug such as doxorubicin (DOX) is widely used in chemotherapy. However, cardiotoxicity of DOX remains to be a serious clinical complication. In the current study, we aim to determine the role of PDE10A and the effect of PDE10A inhibition on cancer growth and cardiotoxicity induced by DOX. METHODS: We used global PDE10A knockout (KO) mice and PDE10A inhibitor TP-10 to block PDE10A function. DOX-induced cardiotoxicity was evaluated in C57Bl/6J mice and nude mice with implanted ovarian cancer xenografts. Isolated adult mouse cardiomyocytes and a human ovarian cancer cell line were used for in vitro functional and mechanistic studies. RESULTS: We found that PDE10A deficiency or inhibition alleviated DOX-induced myocardial atrophy, apoptosis, and dysfunction in C57Bl/6J mice. RNA sequencing study revealed a number of PDE10A-regulated signaling pathways involved in DOX-induced cardiotoxicity. PDE10A inhibition increased the death, decreased the proliferation, and potentiated the effect of DOX on various human cancer cells. Importantly, in nude mice with implanted ovarian cancer xenografts, PDE10A inhibition attenuated tumor growth while protecting DOX-induced cardiotoxicity. In isolated cardiomyocytes, PDE10A contributed to DOX-induced cardiomyocyte death via increasing Top2ß (topoisomerase 2ß) expression, mitochondrial dysfunction, and DNA damage by antagonizing cGMP/PKG (protein kinase G) signaling. PDE10A contributed to cardiomyocyte atrophy via potentiating FoxO3 (forkhead box O3) signaling via both cAMP/PKA (protein kinase A)- and cGMP/PKG-dependent signaling. CONCLUSIONS: Taken together, our study elucidates a novel role for PDE10A in cardiotoxicity induced by DOX and cancer growth. Given that PDE10A has been already proven to be a safe drug target, PDE10A inhibition may represent a novel therapeutic strategy in cancer therapy, with effects preventing DOX-induced cardiotoxicity and simultaneously antagonizing cancer growth.

In 2018, there will be approximately 22,240 new cases of ovarian cancer diagnosed and 14,070 ovarian cancer deaths in the United States. Herein, the American Cancer Society provides an overview of ovarian cancer occurrence based on incidence data from nationwide population-based cancer registries and mortality data from the National Center for Health Statistics. The status of early detection strategies is also reviewed. In the United States, the overall ovarian cancer incidence rate declined from 1985 (16.6 per 100,000) to 2014 (11.8 per 100,000) by 29% and the mortality rate declined between 1976 (10.0 per 100,000) and 2015 (6.7 per 100,000) by 33%. Ovarian cancer encompasses a heterogenous group of malignancies that vary in etiology, molecular biology, and numerous other characteristics. Ninety percent of ovarian cancers are epithelial, the most common being serous carcinoma, for which incidence is highest in non-Hispanic whites (NHWs) (5.2 per 100,000) and lowest in non-Hispanic blacks (NHBs) and Asians/Pacific Islanders (APIs) (3.4 per 100,000). Notably, however, APIs have the highest incidence of endometrioid and clear cell carcinomas, which occur at younger ages and help explain comparable epithelial cancer incidence for APIs and NHWs younger than 55 years. Most serous carcinomas are diagnosed at stage III (51%) or IV (29%), for which the 5-year cause-specific survival for patients diagnosed during 2007 through 2013 was 42% and 26%, respectively. For all stages of epithelial cancer combined, 5-year survival is highest in APIs (57%) and lowest in NHBs (35%), who have the lowest survival for almost every stage of diagnosis across cancer subtypes. Moreover, survival has plateaued in NHBs for decades despite increasing in NHWs, from 40% for cases diagnosed during 1992 through 1994 to 47% during 2007 through 2013. Progress in reducing ovarian cancer incidence and mortality can be accelerated by reducing racial disparities and furthering knowledge of etiology and tumorigenesis to facilitate strategies for prevention and early detection.

Ovarian cancer is one of the most lethal female cancers. For accurate prognosis prediction, this study aimed to investigate novel, blood-based prognostic biomarkers for high-grade serous ovarian carcinoma (HGSOC) using mass spectrometry-based proteomics methods. We conducted label-free liquid chromatography-tandem mass spectrometry using frozen plasma samples obtained from patients with newly diagnosed HGSOC (n = 20). Based on progression-free survival (PFS), the samples were divided into two groups: good (PFS ≥18 months) and poor prognosis groups (PFS <18 months). Proteomic profiles were compared between the two groups. Referring to proteomics data that we previously obtained using frozen cancer tissues from chemotherapy-naïve patients with HGSOC, overlapping protein biomarkers were selected as candidate biomarkers. Biomarkers were validated using an independent set of HGSOC plasma samples (n = 202) via enzyme-linked immunosorbent assay (ELISA). To construct models predicting the 18-month PFS rate, we performed stepwise selection based on the area under the receiver operating characteristic curve (AUC) with 5-fold cross-validation. Analysis of differentially expressed proteins in plasma samples revealed that 35 and 61 proteins were upregulated in the good and poor prognosis groups, respectively. Through hierarchical clustering and bioinformatic analyses, GSN, VCAN, SND1, SIGLEC14, CD163, and PRMT1 were selected as candidate biomarkers and were subjected to ELISA. In multivariate analysis, plasma GSN was identified as an independent poor prognostic biomarker for PFS (adjusted hazard ratio, 1.556; 95% confidence interval, 1.073-2.256; p = 0.020). By combining clinical factors and ELISA results, we constructed several models to predict the 18-month PFS rate. A model consisting of four predictors (FIGO stage, residual tumor after surgery, and plasma levels of GSN and VCAN) showed the best predictive performance (mean validated AUC, 0.779). The newly developed model was converted to a nomogram for clinical use. Our study results provided insights into protein biomarkers, which might offer clues for developing therapeutic targets.

BACKGROUND: Single-agent immune checkpoint inhibitors (ICIs) have demonstrated limited responses in recurrent ovarian cancer; however, 30%-40% of patients achieve stable disease. The primary objective was to estimate progression-free survival (PFS) after sequential versus combination cytotoxic T-lymphocyte antigen 4 and programmed death ligand 1 ICIs in patients with platinum-resistant high-grade serous ovarian cancer (HGSOC). METHODS: Patients were randomized to a sequential arm (tremelimumab followed by durvalumab on progression) or a combination arm (tremelimumab plus durvalumab, followed by durvalumab) via a Bayesian adaptive design that made it more likely for patients to be randomized to the more effective arm. The primary end point was immune-related PFS (irPFS). RESULTS: Sixty-one subjects were randomized to sequential (n = 38) or combination therapy (n = 23). Thirteen patients (34.2%) in the sequential arm received durvalumab. There was no difference in PFS in the sequential arm (1.84 months; 95% CI, 1.77-2.17 months) compared with the combination arm (1.87 months; 95% CI, 1.77-2.43 months) (p = .402). In the sequential arm, no responses were observed, although 12 patients (31.6%) demonstrated stable disease. In the combination arm, two patients (8.7%) had partial response, whereas one patient (4.4%) had stable disease. Adverse events were consistent with those previously reported for ICIs. Patient-reported outcomes were similar in both arms. CONCLUSIONS: There was no difference in irPFS for combination tremelimumab plus durvalumab compared to tremelimumab alone (administered as part of a sequential treatment strategy) in a heavily pretreated population of patients with platinum-resistant HGSOC. Response rates were comparable to prior reports, although the combination regimen did not add significant benefit, as has been previously described.

Although cure rates remain low and effective screening strategies are elusive, the recent advances in systemic therapies over the past year highlighted in this review have prolonged survival for women with ovarian cancer. In 2022, the first antibody-drug conjugate for platinum-resistant ovarian cancer received accelerated US Food and Drug Administration (FDA) approval. Confirmatory studies examining the efficacy of mirvetuximab and other antibody-drug conjugates are underway. In the upfront setting, the first data establishing an overall survival benefit from poly(ADP-ribose) polymerase inhibitor maintenance was demonstrated after a 7-year follow-up period. In contrast, long-term updates from poly(ADP-ribose) polymerase inhibitor trials in the noncurative setting reported survival detriments, and the FDA withdrew the respective indications. Several trials attempted to improve upon the standard of care for platinum-sensitive ovarian carcinoma and those with rare ovarian cancer histologies (carcinosarcoma, clear cell carcinoma) but failed to demonstrate a clinically or statistically meaningful benefit. This leaves the open question of how to further optimize systemic therapy for advanced ovarian carcinoma to improve long-term survival and cure rates.

INTRODUCTION: High-grade serous ovarian cancer (HGSOC) is characterized by high mortality and prevalent recurrences. This study investigates the prognostic value of phosphoglycerate dehydrogenase (PHGDH) in HGSOC which has been linked to metabolic reprogramming and recurrences in other cancers. METHODS: Data from 306 patients with advanced-stage HGSOC treated between 2008 and 2015 were analyzed. PHGDH expression levels were determined using immunohistochemistry and categorized as "low" or "high." RESULTS: PHGDH-high was associated with higher FIGO stage and increased use of neoadjuvant chemotherapy. Patients with PHGDH-high tumors had significantly worse survival than PHDH-low, even after adjusting for confounding factors.

AIMS: The invasive pattern in HPV-associated endocervical adenocarcinoma (HPVA) has prognostic value. Non-destructive (pattern A) HPVA has excellent prognosis mirroring adenocarcinoma in-situ (AIS). However, the rare occurrence of ovarian spread in these tumours suggests aggressiveness in a subset of patients with these otherwise indolent lesions. We hypothesise that AIS/pattern A HPVA with ovarian metastases are biologically different than metastatic destructively invasive HPVA. METHODS AND RESULTS: Samples from patients with HPVA and synchronous or metachronous metastases were retrieved and reviewed to confirm diagnosis and determine the Silva pattern in the primary lesion. For each case, normal tissue, cervical tumour and at least one metastasis underwent comprehensive sequencing using a 447-gene panel. Pathogenic single-nucleotide variants and segmental copy-number alterations (CNA), tumour mutational burden and molecular signatures were evaluated and compared between primary and metastases and among invasive pattern categories. We identified 13 patients: four had AIS/pattern A primaries, while nine had pattern B/C tumours. All AIS/pattern A lesions had metastasis only to ovary; 50% of patients with ovarian involvement, regardless of invasive pattern, also had involvement of the endometrium and/or fallopian tube mucosa by HPVA. In the ovary, AIS/pattern A HPVA showed deceptive well-differentiated glands, often with adenofibroma-like appearance. Conversely, pattern C HPVAs consistently showed overt infiltrative features in the ovary. Sequencing confirmed the genetic relationship between primary and metastatic tumours in each case. PIK3CA alterations were identified in three of four AIS/pattern A HPVAs and three of eight pattern B/C tumours with sequenced metastases. Pattern C tumours showed a notably higher number of CNA in primary tumours compared to pattern A/B tumours. Only one metastatic AIS/pattern A HPVA had a novel pathogenic variant compared to the primary. Conversely, five of eight pattern B/C tumours with sequenced metastases developed novel pathogenic variants in the metastasis not seen in the primary. All four AIS/pattern A patients were alive and free of disease at 31, 47, 58 and 212 months after initial diagnosis. Conversely, cancer-related death was documented in five of nine pattern B/C patients with follow-up at 7, 20, 20, 43 and 87 months. CONCLUSION: Morphologically and genomically, AIS/pattern A HPVA with secondary ovarian involvement appears distinct from destructively invasive tumours. In at least a subset of these cases, ovarian spread appears to occur via trans-Mullerian superficial extension, different from the stromal and lymphatic vascular spread typical of more aggressive tumours (pattern C). These differences may explain the indolent outcome observed in the rare subset of patients with AIS/pattern A HPVA and ovarian metastasis. Our data underscore the potential for conservative surgical management approaches to pattern A HPVA.

OBJECTIVES: To determine the incidence of thromboembolic events (TEEs) in ovarian cancer patients and to identify risk factors that are significantly associated with the development of venous thromboembolism (VTE), arterial thromboembolism (ATE), or overall TEEs in this population. METHODS: This is a retrospective cohort study of 4491 patients with epithelial ovarian cancer identified in the British Columbia cancer registry between 1996 and 2017. The presence of TEEs and risk factors were identified in administrative health records from fee-for-service provider visits and hospital data using ICD-9-CM and ICD-10-CM billing codes. Statistical analysis was performed using Chi-squared test and Fischer's exact test. RESULTS: Of 4491 patients with epithelial ovarian cancer included in this study, 1.74% experienced ATE and (9.44%) experienced VTE. There was a significant association found between the occurrence of TEEs and all-cause mortality. Sepsis was significantly associated with both venous and arterial thromboembolism. The top three risk factors for arterial thromboembolism included peripheral vascular disease (PVD), open wound, and aneurysm. CONCLUSIONS: Risk factors predictive of thrombosis in ovarian cancer patients are not consistent between ATE and VTE, thus thrombotic events should not be combined for analysis. Differential thrombosis risk assessment is needed to improve prevention strategies and guide thromboprophylaxis for these patients.

OBJECTIVES: The phase 2, multicohort, open-label LEAP-005 study evaluated lenvatinib plus pembrolizumab in patients with previously treated advanced solid tumors. We report outcomes from the ovarian cancer cohort. METHODS: Eligible patients had metastatic/unresectable ovarian cancer and had received 3 previous lines of therapy. Patients received lenvatinib 20 mg/day plus pembrolizumab 200 mg every 3 weeks. Treatment continued until progression, unacceptable toxicity, or (for pembrolizumab) completion of 35 cycles. Primary endpoints were objective response rate (ORR) per RECIST version 1.1 and safety. Secondary endpoints included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). RESULTS: Thirty-one patients were enrolled. 39% had high grade serous ovarian cancer, 23% were platinum-sensitive, 55% were platinum-resistant, 23% were platinum-refractory, and 84% had tumors that had a PD-L1 combined positive (CPS) score ≥1. ORR (95% CI) was 26% (12%-45%) by investigator assessment and 35% (19%-55%) by blinded independent central review (BICR). Per BICR, median DOR was 9.2 (1.5+ to 37.8+) months. ORRs (95% CI) by BICR were 35% (9/26 patients; 17%-56%) for PD-L1 CPS ≥ 1 disease and 50% (2/4 patients; 7%-93%) for PD-L1 CPS < 1 disease. Median (95% CI) PFS by BICR and OS were 6.2 (4.0-8.5) months and 21.3 (11.7-32.3) months, respectively. Treatment-related AEs occurred in 94% of patients (grade 3-4, 77%). One patient died from treatment-related hypovolemic shock. CONCLUSIONS: Lenvatinib plus pembrolizumab demonstrated antitumor activity as fourth line therapy in patients with advanced ovarian cancer, and no unanticipated safety signals were identified. Responses were observed regardless of PD-L1 status.

BACKGROUND: Few studies have evaluated the role of cytoreductive surgery in patients with recurrent adult granulosa cell tumors of the ovary. Despite a multitude of treatment modalities in the recurrent setting, the optimal management strategy is not known. Cytoreductive surgery offers an attractive option for disease confined to the abdomen/pelvis. However, few studies have evaluated the role of surgery compared with systemic therapy alone following the first recurrence and subsequent disease progressions. OBJECTIVE: This study aimed to determine the impact of secondary, tertiary, and quaternary cytoreductive surgery on survival outcomes in recurrent adult granulosa cell tumors of the ovary. STUDY DESIGN: This is a multicenter, retrospective cohort study evaluating patients with recurrent adult granulosa cell tumors of the ovary enrolled in the MD Anderson Rare Gynecologic Malignancy Registry from 1970 to 2022. Study inclusion criteria consisted of histology-proven recurrent disease, at least 1 documented recurrence, and treatment/treatment planning at the MD Anderson Cancer Center or Lyndon B. Johnson General Hospital. The primary exposure was cytoreductive surgery, and the outcomes of interest were progression-free survival and overall survival. Survival analyses were restricted to eligible patients with resectable disease without medical barriers to surgery at each progression episode. Demographic and clinicopathologic characteristics were summarized using descriptive statistics. Progression-free survival (after first, second, and third progression) and overall survival were estimated with methods of Kaplan and Meier, and were modeled via Cox proportional hazards regression. Multivariable analyses were performed for progression-free survival after first progression and overall survival. RESULTS: Among the 369 patients with adult granulosa cell tumors of the ovary in the registry, 149 patients met the study inclusion criteria. Secondary cytoreductive surgery was associated with a significant improvement in progression-free survival on univariable (hazard ratio, 0.37; 95% confidence interval, 0.17-0.81, P=.01) and multivariable analyses (hazard ratio, 0.42; 95% confidence interval, 0.19-0.92; P=.03). Those who underwent secondary cytoreductive surgery had a significantly improved median overall survival compared with those who did not undergo cytoreductive surgery (181.92 vs 61.56 months, respectively; P=.002). Overall survival benefit remained statistically significant on multivariable analysis (hazard ratio, 0.28; 95% confidence interval, 0.11-0.67; P=.004). Tertiary cytoreductive surgery was similarly associated with a significant improvement in progression-free survival (hazard ratio, 0.43; 95% confidence interval, 0.26-0.70; P=.001). Despite a similar trend, quaternary cytoreductive surgery was not associated with a significant improvement in progression-free survival (hazard ratio, 0.74; 95% confidence interval, 0.42-1.26; P=.27). CONCLUSION: Among those with resectable disease and no medical contraindications to surgery, cytoreductive surgery may have a beneficial impact on progression-free survival and overall survival in patients with recurrent adult granulosa cell tumors of the ovary.

Ovarian masses encompass various conditions, from benign to highly malignant, and imaging plays a vital role in their diagnosis and management. Ultrasound, particularly transvaginal ultrasound, is the foremost diagnostic method for adnexal masses. Magnetic Resonance Imaging (MRI) is advised for more precise characterisation if ultrasound results are inconclusive. The ovarian-adnexal reporting and data system (O-RADS) MRI lexicon and scoring system provides a standardised method for describing, assessing, and categorising the risk of each ovarian mass. Determining a histological differential diagnosis of the mass may influence treatment decision-making and treatment planning. When ultrasound or MRI suggests the possibility of cancer, computed tomography (CT) is the preferred imaging technique for staging. It is essential to outline the extent of the malignancy, guide treatment decisions, and evaluate the feasibility of cytoreductive surgery. This article provides a comprehensive overview of the key imaging processes in evaluating and managing ovarian masses, from initial diagnosis to initial treatment. It also includes pertinent recommendations for properly performing and interpreting various imaging modalities. KEY POINTS: MRI is the modality of choice for indeterminate ovarian masses at ultrasound, and the O-RADS MRI lexicon and score enable unequivocal communication with clinicians. CT is the recommended modality for suspected ovarian masses to tailor treatment and surgery. Multidisciplinary meetings integrate information and help decide the most appropriate treatment for each patient.
RESUMEN
OBJECTIVE: To assess the association between childhood body fatness and epithelial ovarian cancer (EOC), and whether this association differs by type of EOC. METHODS: Using data from a population-based case-control study (497 cases and 902 controls) in Montreal, Canada conducted 2011-2016, we examined the association between childhood body fatness and EOC, overall and separately for invasive vs. borderline EOCs. A figure rating scale was used to measure body fatness at ages 5 and 10. Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (95% CI). Quantitative bias analyses were conducted to assess the impact of exposure misclassification and non-participation. RESULTS: The aOR (95% CI) of overall EOC for high vs. low body fatness was 1.07 (0.85-1.34) at age 5 and 1.28 (0.98-1.68) at age 10. The associations were stronger for invasive EOC, specifically the endometrioid histological type. For borderline cancers, the aORs were below the null value with wide confidence intervals. Bias analyses did not reveal a strong influence of non-participation. Non-differential exposure misclassification may have biased aORs towards the null for invasive cancers but did not appear to have an appreciable influence on the aORs for borderline cancers. CONCLUSIONS: Childhood body fatness may be a risk factor for invasive EOC in later adult life. Our study highlights the potential importance of examining early life factors for a comprehensive understanding of EOC development.

Ovarian cancer remains the most lethal gynaecological malignancy with 314 000 cases and 207 000 deaths annually worldwide. Ovarian cancer cases and deaths are predicted to increase in Australia by 42% and 55% respectively by 2040. Earlier detection and significant downstaging of ovarian cancer have been demonstrated with multimodal screening in the largest randomised controlled trial of ovarian cancer screening in women at average population risk. However, none of the randomised trials have demonstrated a mortality benefit. Therefore, ovarian cancer screening is not currently recommended in women at average population risk. More frequent surveillance for ovarian cancer every three to four months in women at high risk has shown good performance characteristics and significant downstaging, but there is no available information on a survival benefit. Population testing offers an emerging novel strategy to identify women at high risk who can benefit from ovarian cancer prevention. Novel multicancer early detection biomarker, longitudinal multiple marker strategies, and new biomarkers are being investigated and evaluated for ovarian cancer screening. Risk-reducing salpingo-oophorectomy (RRSO) decreases ovarian cancer incidence and mortality and is recommended for women at over a 4-5% lifetime risk of ovarian cancer. Pre-menopausal women without contraindications to hormone replacement therapy (HRT) undergoing RRSO should be offered HRT until 51 years of age to minimise the detrimental consequences of premature menopause. Currently risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) should only be offered to women at increased risk of ovarian cancer within the context of a research trial. Pre-menopausal early salpingectomy is associated with fewer menopausal symptoms and better sexual function than bilateral salpingo-oophorectomy. A Sectioning and Extensively Examining the Fimbria (SEE-FIM) protocol should be used for histopathological assessment in women at high risk of ovarian cancer who are undergoing surgical prevention. Opportunistic salpingectomy may be offered at routine gynaecological surgery to all women who have completed their family. Long term prospective opportunistic salpingectomy studies are needed to determine the effect size of ovarian cancer risk reduction and the impact on menopause.

A consensus regarding subsequent therapeutic strategies for patients with platinum- and poly (ADP-ribose) polymerase inhibitor (PARPi)-resistant ovarian cancer is lacking. These patients typically receive non-platinum-based chemotherapy; however, survival outcomes remain poor. Compared with chemotherapy alone, combination therapy with novel target agents can provide additional benefits to these patients. Oregovomab, an investigational murine monoclonal antibody against CA-125, has shown promising efficacy in a phase II study in patients with recurrent ovarian cancer. Herein, we described the rationale and design of OPERA/KGOG 3065/APGOT-OV6, a multicenter, investigator-initiated, two-cohort, single-arm phase II trial, aimed at examining the efficacy of oregovomab plus non-platinum-based chemotherapy in patients with PARPi/platinum-resistant ovarian cancer. The primary end point was the objective response rate, according to RECIST 1.1.Clinical Trial Registration: NCT05407584 (ClinicalTrials.gov).
OPERA/KGOG 3065/APGOT-OV6 is a promising phase II studies that test new drug (oregovomab) on the patients with poly (ADP-ribose) polymerase inhibitor (PARPi)/platinum-resistant epithelial ovarian cancer. PARPis have changed the treatment landscape of ovarian cancer in a relatively short time. PARPi/platinum-resistant epithelial ovarian cancer refer to a subtype of recurrent epithelial cancer of ovarian, tubal or peritoneal origin who experienced disease progression despite treatment with a PARPi or platinum-based chemotherapy drugs. Although various new drugs have been tested to improve the treatment response in resistant patients, a consensus regarding the international standard of treatment is yet to be established, despite the poor survival outcomes of these patients. OPERA/KGOG 3065/APGOT-OV6 has been designed to add oregovomab, a murine monoclonal antibody to cancer antigen-125 (CA-125), to non-platinum chemotherapy (pegylated liposomal doxorubicin or paclitaxel) for patients with ovarian cancer determined as PARPi/platinum-resistant and ineligible for bevacizumab treatment. The results of this study will aid in developing effective treatment strategies for patients with PARPi/platinum-resistant ovarian cancer.
RESUMEN
OBJECTIVE: The single-arm, phase II SORAYA trial (NCT04296890) of mirvetuximab soravtansine-gynx in folate receptor alpha (FRα)-high platinum-resistant ovarian cancer (n=105 (efficacy-evaluable)) met its primary endpoint with an objective response rate of 32.4% (95% CI, 23.6 to 42.2). Here we report final SORAYA trial results for overall survival and post hoc objective response rates in subgroups by sequence and number of prior therapies. METHODS: Eligible patients had high-grade serous platinum-resistant ovarian cancer with high FRα expression and one to three prior therapies (prior bevacizumab required). Enrolled participants received 6 mg/kg mirvetuximab soravtansine-gynx adjusted ideal body weight intravenously once every 3 weeks until progressive disease, unacceptable toxicity, withdrawal of consent, or death. Final overall survival and post hoc objective response rates were assessed in efficacy-evaluable participants. The safety population included all patients who received ≥1 dose of mirvetuximab soravtansine-gynx. RESULTS: At data cut-off (December 22, 2022; n=105), final median overall survival was 15.0 months (95% CI, 11.5 to 18.7). Median overall survival in participants with one to two prior therapy lines was 18.7 months (95% CI, 13.8 to not estimable (NE)) and 11.6 months (95% CI, 7.1 to 16.7) with three prior therapy lines. Median overall survival was 15.0 months (95% CI, 11.5 to NE) in participants with prior poly (ADP-ribose) polymerase inhibitor (PARPi) treatment versus 14.0 months (95% CI, 7.1 to NE) in those without. Objective response rate (data cut-off: November 17, 2021) differed among participants who received mirvetuximab soravtansine-gynx as their first treatment in the platinum-resistant setting (34.8%; 95% CI, 23.5 to 47.6) versus a different first treatment (28.2%; 95% CI, 15.0 to 44.9) or had received prior bevacizumab in a platinum-sensitive (34.0%; 95% CI, 24.6 to 44.5) versus platinum-resistant setting (17.6%; 95% CI, 3.8 to 43.4). No new safety signals were observed. CONCLUSION: These results support the clinically meaningful efficacy of mirvetuximab soravtansine-gynx in FRα-expressing platinum-resistant ovarian cancer, irrespective of prior treatment or sequence.

OBJECTIVES: The aim of our study was to evaluate the feasibility of the modified International Germ Cell Cancer Collaborative Group risk classification system in Chinese female patients with malignant ovarian germ cell tumors and to identify predictive factors to enhance the risk classification system. METHODS: In this retrospective cohort analysis, patients with malignant ovarian germ cell tumors who received surgery with/without chemotherapy were included. These patients had been followed-up by Peking Union Medical College Hospital between 2011 to 2020. Patients without complete medical records or no follow-up information were excluded. RESULTS: The study enrolled a total of 271 patients. The risk model classified 106 (39.1%) patients as good-, 84 (31%) as intermediate-, and 81 (29.9%) as poor-risk. With a median follow-up time of 34 months (range 2-147), 48 (17.7%) recurrence and 16 (5.9%) deaths were observed. The risk classification significantly correlated with 3 year disease-free survival and overall survival (log rank p<0.001 and p=0.003, respectively). The survival outcomes of disease-free survival and overall survival were not statistically different among risk groups in patients who received neoadjuvant chemotherapy (log rank p=0.77 and 0.41, respectively). Univariate and multivariable analysis showed that tumor stage (p=0.033, hazard ratio (HR) 2.05, 95% confidence interval (CI) 1.06 to 3.96) was significantly associated with relapse or progression of disease. Patients over age 40 years exhibited a poor prognosis. CONCLUSION: The modified International Germ Cell Cancer Collaborative Group risk classification system was efficacious in patients with malignant ovarian germ cell tumors and was significantly associated with disease-free survival and overall survival. Risk assessment after neoadjuvant chemotherapy may be more predictive than stratification at initial diagnosis. Age and tumor stage were definitive prognostic factors for germ cell tumors, which may need to be incorporated in the stratification system.
RESUMEN
OBJECTIVE: To evaluate the impact of adjuvant chemotherapy, type of ovarian surgery, and the surgical approach on fertility in patients with stage I immature teratoma of the ovary. METHODS: Clinicopathologic data were retrospectively collected and analyzed from a cohort of 47 patients with childbearing desire treated for a stage I immature teratoma of the ovary at IRCCS San Gerardo dei Tintori Hospital, Monza, Italy. Multivariate logistic regression was used to address the influence of chemotherapy and type of surgery on the outcome. RESULTS: Among the patients included, 78.7% (37/47) were able to get pregnant, with a live birth rate of 80.9% (51/63 pregnancies). These rates were not different between adjuvant chemotherapy versus surveillance group (62.5% (5/8) and 82.0% (32/39), respectively; p=0.22) nor between the type of ovarian surgery (cystectomy vs unilateral salpingo-oophorectomy; p=0.57) and surgical approach (laparotomy or laparoscopy; p=0.18). A statistically significant difference was found for stage of disease (a decrease in pregnancy rate from 86.5% (32/37) for stage IA to 50.0% for stage IC (5/10); p=0.02), but it was not confirmed in the multivariate analysis. After relapse diagnosis and management, a total of 62.5% (5/8) of patients conceived and had at least one live birth baby. CONCLUSIONS: The fertility-sparing approach is feasible in this population, and fertility does not depend on surgical approach or post-operative treatment. However, adjuvant chemotherapy should be carefully evaluated in this setting.

Epithelial ovarian cancer most commonly presents at advanced stages, and prognosis is influenced by residual disease following cytoreduction. The significance of cardiophrenic lymph node resection at the time of cytoreductive surgery in advanced ovarian cancer remains a topic of debate. Enlarged cardiophrenic lymph nodes are detected through high-resolution imaging; however, the optimal imaging technique in determining feasibility of node resection remains uncertain. Similarly, the impact of excision of cardiophrenic lymph nodes on progression-free and overall survival remains elusive. The indications for resection of cardiophrenic lymph nodes are not addressed in standard ovarian cancer guidelines. Patients with cardiophrenic lymph nodes exceeding 1 cm in size may be considered for resection if complete intra-abdominal cytoreduction is feasible to no gross residual. The surgical approach might be either by open access or by video-assisted thoracoscopic surgery (minimally invasive approach), and major complications following cardiophrenic lymph nodes resection are low. Pathological cardiophrenic lymph nodes are associated with a poorer overall prognosis and can serve as a prognostic parameter; however, the therapeutic benefit of cardiophrenic lymph nodes resection remains inconclusive.
