RESUMO
INTRODUCTION: Relacorilant (CORT125134, Corcept Therapeutics) is a selective glucocorticoid receptor modulator, which reverses the glucocorticoid-mediated anti-apoptotic effects and restores the taxane chemosensitivity in epithelial ovarian cancer cells. Given those preclinical findings, relacorilant is currently under investigation in clinical trials in combination with nab-paclitaxel for the platinum-resistant ovarian cancer setting. AREAS COVERED: Already published preclinical and clinical evidence of relacorilant antitumor activity was analyzed and discussed. Ongoing clinical trials registered on clincaltrials.gov were also reported. The review aimed to summarize the status of relacorilant, the mechanism of action, the published and ongoing trials, and its safety and efficacy. EXPERT OPINION: Relacorilant combined with nab-paclitaxel, may represent a promising strategy for the treatment of platinum-resistant ovarian cancer patients. After preliminary positive results in terms of clinical efficacy, a randomized phase III trial is ongoing to confirm the findings from the published phase II study.

OBJECTIVES: Despite the individualized starting dose for maintenance therapy in ovarian cancer, the niraparib dose reduction rate remains high. The aim of this study was to evaluate the impact of niraparib dose reduction on progression-free survival in newly diagnosed primary advanced ovarian cancer and recurrent ovarian cancer patients. We also aimed to compare the reduction rates and the safety of niraparib on primary and relapse groups, and identify which factors may predict dose reduction. METHODS: Patients with primary or recurrent ovarian cancer in maintenance who received niraparib between 2019 and 2022 were retrospectively evaluated. Niraparib dosing was based on individualized starting dose of 300 or 200 mg/day. The impact of niraparib dose reductions was focused on patients treated with 200 or 100 mg in both groups. Reduction rates, adverse events and predictive factors of reduction were assessed in each study group. The primary endpoint was progression-free survival in primary and relapse groups; the secondary endpoints were the reduction rates, the safety and tolerability of niraparib in both groups. RESULTS: Of 215 patients identified, 124 (57.7%) primary and 91 (42.3%) recurrent ovarian cancer patients were included. The majority of patients started niraparib at 200 mg/day (92.7% primary and 80.2% relapse group); dose reductions from 300 or 200 mg/day to 200 or 100 mg/day occurred more frequently within cycles 1-3 (67% primary and 45% relapse group, p=0.001). Grade≥3 adverse events were lower in the relapse group (54.8% primary and 35.1% relapse, p=0.001). In both groups, dose modifications over the treatment did not significantly impair median progression-free survival. Univariate and multivariate analysis demonstrated that weight and platinum-doublets were possible risk factors for dose reduction. CONCLUSIONS: Niraparib dose reduction occurs in almost half of patients within cycles 1-3, although it is significantly more common in the first-line setting. Survival outcomes seem not to be impaired by dose reduction.
RESUMO
In the era of single and combination maintenance therapies as well as platinum and Poly (ADP-ribose) polymerase inhibitors (PARPi) resistance, the choice of subsequent treatments following first-line platinum-based chemotherapy in recurrent ovarian cancer (ROC) patients has become increasingly complex. Within the ovarian cancer treatment algorithm, particularly in the emerging context of PARPi resistance, the role of trabectedin, in combination with pegylated liposomal doxorubicin (PLD) still preserves its significance. This paper offers valuable insights into the multifaceted role and mechanism of action of trabectedin in ROC. The main results of clinical trials and studies involving trabectedin/PLD, along with hints of Breast Cancer genes (BRCA)-mutated and BRCAness phenotype cases, are critically discussed. Moreover, this review provides and contextualizes potential scenarios of administering trabectedin in combination with PLD in ROC, according to established guidelines and beyond.

OBJECTIVE: To evaluate disease characteristics and survival according to BRCA status, administration of poly-(ADP-ribose) polymerase inhibitors (PARPi), and surgery in patients with ovarian cancer and brain metastases. METHODS: This is a monocentric retrospective cohort of patients with ovarian cancer and brain metastases treated between 2000 and 2021. Data were collected by a retrospective review of medical records and analyzed according to: (1) BRCA mutation; (2) PARPi before and after brain metastases; (3) surgery for brain metastases. RESULTS: Eighty-five patients with ovarian cancer and brain metastasis and known BRCA status (31 BRCA mutated (BRCAm), 54 BRCA wild-type (BRCAwt)) were analyzed. Twenty-two patients had received PARPi before brain metastases diagnosis (11 BRCAm, 11 BRCAwt) and 12 after (8 BRCAm, 4 BRCAwt). Brain metastases occurred >1 year later in patients who had received previous PARPi. Survival was longer in the BRCAm group (median post-brain metastasis survival: BRCAm 23 months vs BRCAwt 8 months, p=0.0015). No differences were found based on BRCA status analyzing the population who did not receive PARPi after brain metastasis (median post-brain metastasis survival: BRCAm 8 months vs BRCAwt 8 months, p=0.31). In the BRCAm group, survival was worse in patients who had received previous PARPi (median post-brain metastasis survival: PARPi before, 7 months vs no-PARPi before, 24 months, p=0.003). If PARPi was administered after brain metastases, survival of the overall population improved (median post-brain metastasis survival: PARPi after, 46 months vs no-PARPi after, 8 months, p=0.00038).In cases of surgery for brain metastases, the prognosis seemed better (median post-brain metastasis survival: surgery 13 months vs no-surgery 8 months, p=0.036). Three variables were significantly associated with prolonged survival at multivariate analysis: BRCA mutation, multimodal treatment, and ≤1 previous chemotherapy line. CONCLUSIONS: BRCA mutations might impact brain metastasis occurrence and lead to better outcomes. In a multimodal treatment, surgery seems to affect survival even in cases of extracranial disease. PARPi use should be considered as it seems to prolong survival if administered after brain metastasis.

OBJECTIVE: To investigate the role of BRCA1/2 mutations in early ovarian cancer (eOC) (International Federation of Gynecology and Obstetrics FIGO 2014 stage I-II), and its impact on prognosis after relapse. METHODS: In this multicenter retrospective study, clinical and survival data from high-grade serous (HGS)-eOC patients at presentation and recurrence were compared according to BRCA status: BRCA-mutated (BRCAmut) vs. BRCA wild-type (BRCAwt). RESULTS: Among 191 HGS-eOC patients, 89 were BRCAmut and 102 BRCAwt. There was no significant difference according to the BRCA status in terms of Progression-Free Survival (PFS). A longer Overall Survival (OS) was found in BRCAmut patients. Stage I patients had significantly improved PFS vs stage II, regardless of BRCA status. At multivariate analysis, stage at diagnosis was the only variable with a significant effect on PFS. No factors were significantly relevant on OS, albeit younger age and BRCA mutation showed a slight impact. Post-Recurrence Survival (PRS) in the BRCAmut population was significantly improved compared with BRCAwt. At multivariate analysis, Secondary Cytoreductive Surgery was the strongest predictor for longer PRS, followed by PARPi maintenance at recurrence. CONCLUSIONS: BRCA-status is not a prognostic factor in early ovarian cancer regarding PFS. However, our data suggest a better prognosis after relapse in BRCAm population.

OBJECTIVE: The study aimed to characterize intra-and postoperative complications according to a standardized anatomo-surgical classification for ovarian cancer metastases in the liver area. METHODS: Data from all patients with advanced ovarian cancer undergoing primary or secondary surgery with perihepatic liver involvement (May-2016 to May-2022), were retrospectively retrieved and classified according to a standardized anatomo-surgical classification, and clustered into four Classes: Class I "Peritoneal", Class II "Hepatoceliac-lymph-nodes", Class III "Parenchymal" and Class IV Mixed (≥ 2 classes). RESULTS: Data from 615 patients were collected. Intraoperative complications were observed in 15%, and severe postoperative complications in 17.6% of cases. While surgical complexity scores were similar, Class IV had longer operative times, higher blood loss, and a 30.4% intraoperative transfusion rate. Class II showed a higher prevalence of vascular injuries (8%). Classes II and IV were significantly associated with severe postoperative complications. Specific complications varied among classes, such as perihepatic collection and intrahepatic hematoma/abscess in Class III (p = 0.003, p < 0.001, respectively), and pleuric effusion, sepsis, anemia, and "other complications" in Class IV (p = 0.002, p = 0.004, p = 0.03, p = 0.03, respectively). Multivariable analysis identified Class II and IV (Class II: OR 4.991, p = 0.045; Class IV: OR 5.331, p = 0.030), Surgical Complexity Score group 3 (OR:3.922, p = 0.003), and the presence of residual tumor (OR:1.748, p = 0.048) as independent risk factors for severe postoperative complications. CONCLUSIONS: Liver procedures during advanced ovarian cancer surgery are feasible with acceptable complication rates According to the anatomo-surgical classification, metastatic patterns are related to both different surgical outcomes and postoperative complication profiles.

Hereditary breast and ovarian cancer syndrome is an autosomal dominant cancer susceptibility syndrome mainly due to variants in BRCA1 or BRCA2 genes. Patients presenting with BRCA1 or BRCA2 gene mutations have a lifetime risk of developing breast or ovarian cancer (80% and 40%, respectively). Genetic testing to explore the predisposition to develop cancer represents a pivotal factor in such cases, and this review wants to explore the main implications in terms of medicolegal liability and insurance issues. Medicolegal issues related to these diagnostic processes include: (a) failure to recommend the test; (b) failure to properly interpret the test; (c) failure to correctly translate results into clinical practice; (d) lack of informed consent; and (e) failure to refer patients to specialized genetic counseling. Such errors may lead to compensation since the legal burden inherent in the efficacy of prophylactic interventions is a proof that requires the so-called 'preponderance of the evidence'. Concerning insurance issues, the carriers of such alleles without cancer are healthy because the genetic predisposition is not a disease per se but represents a (relevant) health risk. However, disclosure of these conditions can be impelled by insurers. It can lead to so-called 'genetic discrimination' because insurance companies might use genetic information to limit insurance options or increase their costs. Many private and public healthcare funders do not cover risk reducing surgeries, even when recommended as part of a risk reduction management plan for BRCA gene mutation carriers. Here, positions on these matters from different high income countries are discussed, stressing the importance of a common supranational or international regulatory framework to reach a trade-off between the economic interests of insurers and the rights of carriers not to disclose extremely sensitive information.

Precision medicine through molecular profiling has taken a prominent role in the treatment of solid tumors and it is widely expected that this will continue to expand. With respect to gynecological cancers, a major change has particularly been observed in the treatment landscape of epithelial ovarian, endometrial, and cervical cancers. Regarding the former, maintenance therapy with either poly(ADP-ribose) polymerase inhibitors (PARPi) and/or bevacizumab has become an indispensable treatment option following the traditional combination of cytoreductive surgery and platinum-based chemotherapy. Considering endometrial cancer, the molecular classification system has now been incorporated into virtually every guideline available and molecular-directed treatment strategies are currently being researched, presumably leading to a further transformation of its treatment paradigm. After all, treatment with immune-checkpoint inhibitors that target the programmed cell death 1 (PD-1) receptor has already been shown to significantly improve disease outcomes in these patients, especially in those with mismatch repair deficient, microsatellite stability-high (MMRd-MSI-H) disease. Similarly, in recurrent/metastatic cervical cancer patients, these agents elicited improved survival rates when being added to platinum-based chemotherapy with or without bevacizumab. Interestingly, implications of these targeted therapies for surgical management have been touched on to a minor extent, but are at least as intriguing. This review therefore aims to address the wide-ranging opportunities the molecular tumor characteristics and their corresponding targeted therapies have to offer for the surgical management of epithelial ovarian, endometrial, and cervical cancers, both in the primary and recurrent setting.

OBJECTIVE: In the era of target therapy and personalized medicine, BRCA mutational status has a major influence on survival in ovarian cancer patients. Our aim is to verify if the poorer prognosis of elderly ovarian cancer patients can be related to the biology of the tumor beyond their own morbidities and/or suboptimal treatments. METHODS: This is a retrospective single-institution study evaluating prognosis of patients with a diagnosis of ovarian cancer and known BRCA status. We collected clinical and surgical characteristics and the distribution of BRCA mutational status according to age groups. RESULTS: 1840 patients were included in the analysis. The rate of BRCA mutated decreased over age-range from 49.7% in patients aged <50 years to 18.8% in ≥80 years old women. The prognostic role of BRCA status on survival is maintained when focusing on the elderly population, with improved Disease Free Survival (27.2 months vs 16.5 months for BRCA mutated and wild type respectively, p = 0.001) and Cancer Specific Survival (117.6 months vs 43.1 months for BRCA mutated and wild type respectively, p = 0.001) for BRCAmut compared to BRCAwt patients. In the multivariable analysis, among elderly women, upfront surgery and BRCA mutation are independent factors affecting survival. CONCLUSIONS: Elderly patients experiment a poorer prognosis due to multiple factors that include both their medical condition and comorbidities, under-treatment and most importantly disease characteristics. We found that beyond disparities, BRCA mutation is still the strongest independent prognostic factor affecting both the risk of recurrence and death due to disease.

INTRODUCTION: Tubo-ovarian carcinomas (OCs) are highly sensitive to platinum-based neoadjuvant chemotherapy (NACT) but almost never demonstrate complete pathologic response. METHODS: We analyzed paired primary and residual tumor tissues from 30 patients with hereditary BRCA1/2-driven OCs (BRCA1: 17; BRCA2: 13), who were treated by carboplatin/paclitaxel NACT (median number of cycles: 3, range: 3-6). BRCA1/2 and TP53 genes were analyzed by the next-generation sequencing. The ratio between TP53 mutation-specific versus wild-type reads was considered to monitor the proportion of tumor and non-tumor cells in the tissue sample, and the ratio between BRCA1/2-mutated and wild-type reads was used to estimate the presence of cells with the loss or retention of heterozygosity (LOH or ROH, respectively). RESULTS: All 30 OCs had BRCA1/2 LOH in primary tumor and carried somatic TP53 mutation. Twenty-eight OCs had sufficient tumor cell cellularity in the post-NACT tissue to evaluate the ratio between mutated and wild-type BRCA1/2 alleles. Five (18%) out of 28 informative tumor pairs showed transition from LOH to ROH during NACT presumably affecting all or the vast majority of residual tumor cells. There were no signals of the emergence of a second open reading frame-restoring BRCA1/2 mutation. CONCLUSION: Chemonaive BRCA1/2-driven carcinomas may contain a fraction of tumor cells with preserved BRCA1/2 heterozygosity. NACT can cause a selection of pre-existing BRCA1/2-proficient tumor cells, without gaining secondary reversal BRCA1/2 mutations.

During withdrawal from cocaine, calcium permeable-AMPA receptors (CP-AMPAR) progressively accumulate in nucleus accumbens (NAc) synapses, a phenomenon linked to behavioral sensitization and drug-seeking. Recently, it has been suggested that neuroimmune alterations might promote aberrant changes in synaptic plasticity, thus contributing to substance abuse-related behaviors. Here, we investigated the role of microglia in NAc neuroadaptations after withdrawal from cocaine-induced conditioned place preference (CPP). We depleted microglia using PLX5622-supplemented diet during cocaine withdrawal, and after the place preference test, we measured dendritic spine density and the presence of CP-AMPAR in the NAc shell. Microglia depletion prevented cocaine-induced changes in dendritic spines and CP-AMPAR accumulation. Furthermore, microglia depletion prevented conditioned hyperlocomotion without affecting drug-context associative memory. Microglia displayed fewer number of branches, resulting in a reduced arborization area and microglia control domain at late withdrawal. Our results suggest that microglia are necessary for the synaptic adaptations in NAc synapses during cocaine withdrawal and therefore represent a promising therapeutic target for relapse prevention.

OBJECTIVE: Retrospective series have shown secondary cytoreductive surgery improves oncological outcomes in recurrent low-grade serous ovarian cancer. We aim to compare surgical procedures and complications between patients with low-grade and high-grade recurrent serous ovarian cancer. METHODS: This retrospective single-institution study includes patients with recurrent low-grade and high-grade serous ovarian cancer undergoing surgery between January 2012 to December 2021. Patients were propensity matched 1:3 for residual tumor at first surgery, presence of ascites and performance status. Complexity of surgery and postoperative complications were analyzed. RESULTS: A total of 116 patients undergoing secondary cytoreductive surgery were included with 29 patients (25%) having low-grade ovarian cancer. The median age of the patients was 54 years (range: 19-85) and 57 years (range: 29-78) in low-grade and high-grade ovarian cancer, respectively (p=0.13). Stages III/IV at diagnosis were more frequent in patients with high-grade ovarian cancers (p<0.001). Peritoneal involvement was higher in low-grade compared with high-grade ovarian cancer as shown by the higher rate of diaphragmatic (41.4% vs 21.8%, p=0.05), abdominal wall (41.4% vs 18.4%, p=0.02) and pelvic (51.7% vs 21.8%, p=0.01) peritonectomy. Multiple bowel resections were higher in low-grade ovarian cancer (24.1% vs 8.0%, p=0.04), while high-grade ovarian cancer had a higher rate of nodal recurrences (73.2%% vs 37.9%, p=0.03). Overall, surgical complexity was higher in low-grade ovarian cancer (58.6% vs 36.8%; p=0.05), with higher median estimated blood loss (400 vs 200 mL; p=0.01) compared with high-grade. Complete cytoreduction was achieved in 26 patients (89.7%) with low-grade and 84 (96.6%) with high-grade (p=0.16) ovarian cancer, with no significant differences in postoperative complications. CONCLUSIONS: Secondary cytoreductive surgery in low-grade serous ovarian cancer patients was associated with higher complexity, multiple bowel resections, and higher median estimated blood loss than in high-grade serous ovarian cancer. The comparable rate of postoperative complications suggests that secondary cytoreductive surgery in this group of patients is feasible in expert centers.

Breast cancer susceptibility gene 1 (BRCA1) and breast cancer susceptibility gene 2 (BRCA2) deleterious variants were the first and, still today, the main biomarkers of poly(ADP)ribose polymerase (PARP)-inhibitors (PARPis) benefit. The recent, increased, numbers of individuals referred for counseling and multigene panel testing, and the remarkable expansion of approved PARPis, not restricted to BRCA1/BRCA2-Pathogenic Variants (PVs), produced a strong clinical need for non-BRCA biomarkers. Significant limitations of the current testing and assays exist. The different approaches that identify the causes of Homologous Recombination Deficiency (HRD), such as the germline and somatic Homologous Recombination Repair (HRR) gene PVs, the testing showing its consequences, such as the genomic scars, or the novel functional assays such as the RAD51 foci testing, are not interchangeable, and should not be considered as substitutes for each other in clinical practice for guiding use of PARPi in non-BRCA, HRD-associated tumors. Today, the deeper knowledge on the significant relationship among all proteins involved in the HRR, not limited to BRCA, expands the possibility of a successful non-BRCA, HRD-PARPi synthetic lethality and, at the same time, reinforces the need for enhanced definition of HRD biomarkers predicting the magnitude of PARPi benefit.

OBJECTIVE: To investigate the effect of treatment with neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS), versus primary debulking surgery (PDS), on quality of life (QoL) in patients with advanced epithelial ovarian cancer (EOC). DESIGN: Randomised trial conducted in a single institution. SETTING: Division of Gynaecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. SAMPLE: Patients with stage-IIIC/IV EOC and high tumour load. METHODS: Patients were randomised (1:1) to undergo either PDS (PDS group) or NACT followed by IDS (NACT/IDS group). MAIN OUTCOME MEASURES: Quality-of-life (QoL) data, assessed using the European Organization for Research and Treatment of Cancer core QoL questionnaire (QLQ-C30) and ovarian cancer module (OV28); co-primary outcomes were the QLQ-C30 global health score at 12 months (cross-sectional analysis) and the difference in mean QLQ-C30 global health score over time between treatment groups (longitudinal analysis). RESULTS: From October 2011 to May 2016, 171 patients were enrolled (PDS = 84; NACT/IDS = 87). We observed no clinical or statistically significant difference between treatment groups in any of the QoL functioning scales at 12 months, including QLQ-C30 global health score (NACT/IDS group vs PDS group, mean difference 4.7, 95% CI -4.99 to 14.4, p = 0.340). Over time, we found lower global health scores for those undergoing PDS than for those receiving NACT (difference in mean score 6.27, 95% CI 0.440-12.11, p = 0.035), albeit this was not clinically relevant. CONCLUSIONS: We found no difference in global QoL related to treatment approach at 12 months, even though patients in the NACT/IDS group reported better global health scores across the 12-month period compared with the PDS group; these findings further confirm that NACT/IDS might be a feasible option for patients unsuitable for PDS.

INTRODUCTION: In patients with newly diagnosed advanced high-grade serous and endometrioid epithelial ovarian cancer (EOC) first-line maintenance therapy with poly(ADP-ribose) polymerase inhibitors (PARPi) tremendously improved progression-free survival (PFS). Yet, data on the effect of PARPi in proportion to postoperative residual disease status were lacking. MATERIAL AND METHODS: A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items of Systematic reviews and Meta-Analysis (PRISMA) guidelines. We searched Medline/Pubmed, Embase and Cochrane databases as well as meeting abstracts until 18th March 2023. Hazard ratios (HRs) alongside their 95% confidence intervals (CIs) for PFS were extracted from the studies. A subgroup analysis was conducted to examine the effect of PARPi according to postoperative residual disease. RESULTS: A total of six phase III randomised controlled trials were included and comprised SOLO 1, PAOLA 1, PRIMA, PRIME, ATHENA-MONO and VELIA. Patients who received PARPi following complete gross resection showed greatest PFS benefit. Compared with placebo, maintenance with PARPi significantly improved PFS in patients with macroscopic residual disease (pooled HR 0.55; 95% CI 0.44-0.68). This magnitude was comparable to that found in patients with complete gross resection (pooled HR 0.53; 95% CI 0.41-0.67). CONCLUSIONS: Patients with macroscopic residual disease benefit from PARPi at the same extent as cases with complete gross resection. However, patients with complete gross resection who were treated with PARPi show the most favourable PFS rates. Hence, the pursuit of achieving complete cytoreduction remains valid in the PARPi era.

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease.

OBJECTIVE: The aim of the present analysis was to explore the efficacy of Bevacizumab (Bev) on survival outcome in advanced low grade serous ovarian cancer (LGSOC) both in first line and in recurrent setting. METHODS: In retrospective observational multicenter study, we described the outcome of LGSOC patients enrolled in the MITO 22 study and treated with chemotherapy (CT) with or without Bev. Patients receiving Bev in first-line or in recurrence were considered and compared with patients receiving CT alone (stage III and IV in first line; platinum based-CT in second line). Descriptive and survival analyses were performed for each group. RESULTS: Out of 128 patients included in MITO 22, 46 LGSOC patients receiving Bev in first line setting or at the time of first recurrence were identified. In first line, 30 patients received Bev + CT and 65 CT alone and the median PFS were 47.86 months (95% CI: 31.48 - NR) and 22.63 months (95% CI 15-39.24) (p-value 0.0392), respectively. In the recurrent setting, 16 patients who received Bev + CT were compared to 33 women treated with platinum-based CT alone. Median PFS were 37.1 months (95% CI: 13.42-40.56) and 11.22 months (95% CI: 8.26-15.63) (p-value 0.013), respectively. CONCLUSIONS: Our study suggests that Bev might be effective in LGSOC both at diagnosis and at the time of relapse. These data warrants further studies.

PURPOSE: To evaluate the role of upper-neck irradiation versus standard whole-neck irradiation in patients with N0-1 nasopharyngeal carcinoma. METHODS: We conducted a PRISMA guideline based systematic review and meta-analysis. Randomized clinical trials assessing upper-neck irradiation versus whole-neck irradiation with or without chemotherapy in non-metastatic N0-1 nasopharyngeal carcinoma patients were identified. The studies were searched on the PubMed, Embase and Cochrane library up to March 2022. Survival outcomes, including overall survival, distant metastasis-free survival and relapse-free survival, and toxicities rate were evaluated. RESULTS: There were two randomized clinical trials with 747 samples finally included. Upper-neck irradiation had similar overall survival (hazard ratio = 0.69, 95% confidence interval = 0.37-1.30), distant metastasis-free survival (hazard ratio = 0.92, 95% confidence interval = 0.53-1.60) and relapse-free survival (risk ratio = 1.03, 95% confidence interval = 0.69-1.55) compared to whole-neck irradiation. No differences in both acute and late toxicities were recorded between upper-neck irradiation and whole-neck irradiation. CONCLUSION: This meta-analysis supports the potential role of upper-neck irradiation in this population of patients. Further research is needed to confirm results.

OBJECTIVE: Correlation between BRCA1/2 (BRCA) pathogenic variants and the response to poly (ADP-ribose) polymerase inhibitors (PARPi) has been recognized in patients with ovarian cancer. Moreover, data on the clinical implications of variants of unknown significance are lacking. The aim of this study was to evaluate differences in survival outcomes in patients with BRCA variants of unknown significance, mutated, and wild type relapsed ovarian cancer treated with PARPi. METHODS: Patients with ovarian cancer whose somatic BRCA testing was available and who were receiving PARPi as maintenance treatment at the first recurrence between January 2014 and January 2021 were included in the present study and analyzed. Patients were divided into three groups according to BRCA mutational status (variant of unknown significance, mutated, and wild type). Progression-free survival was assessed in each study group. RESULTS: Of 67 patients identified, 20 (29.9%), 24 (35.8%), and 23 (34.3%) had BRCA variant of unknown significance, mutated, and wild type, respectively. Patients received PARPi as maintenance treatment at the time of the first relapse after a complete response or partial response to platinum-based chemotherapy without differences in the previous platinum-free interval among the analyzed groups. The median progression-free survival of patients with BRCA mutation was significantly longer than for those with BRCA wild type or variant of unknown significance (not reached vs 4 months vs 7 months, respectively; p<0.001). Additionally, no significant difference was found between patients with BRCA wild type and BRCA variant of unknown significance (p=0.50). CONCLUSION: Our study suggests that carriers of BRCA variant of unknown significance have survival outcomes comparable to patients with BRCA wild type and shorter progression-free survival than women harboring BRCA pathogenic variants.
