RESUMEN
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.
RESUMEN
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: Poly (ADP-ribose) polymerase (PARP) inhibitor resistance is problematic in epithelial ovarian cancer management and sequencing strategies may be performed to overcome this issue. In this context, our study evaluated the role of non-platinum doublet pegylated liposomal doxorubicin/trabectedin in ovarian cancer platinum-sensitive patients who experienced disease progression under PARP inhibitor maintenance. METHODS: This case-control study includes patients with recurrent epithelial ovarian cancer treated between March 2016 and April 2021 who progressed under PARP inhibitor maintenance. Data of patients treated with pegylated liposomal doxorubicin/trabectedin (experimental group) were matched 1:1 with a series of patients who received platinum-based treatment (control group). The study outcomes were overall clinical benefit (including complete, partial, and stable response), progression-free survival, and overall survival. The safety of both treatments was also evaluated. RESULTS: A total of 26 patients in both groups were analyzed. Clinical benefit was achieved in 15 (57%) patients in the study group and 17 (65%) patients in the control group (p=0.38). Patients receiving pegylated liposomal doxorubicin/trabectedin had 5 months of progression-free survival, compared with 5 months in patients treated with platinum-based treatment (p=0.62). Patients in the experimental group achieved a median overall survival of 16 months compared with 19 months in the control group (p=0.26) There was no difference concerning severe toxicities (G3-G4) between groups, except for hepatic toxicity, which was experienced in 30% of the patients receiving pegylated liposomal doxorubicin/trabectedin and none in the control group (p<0.009). CONCLUSIONS: Pegylated liposomal doxorubicin/trabectedin might be an alternative option to platinum-based treatment in patients experiencing disease progression during PARP inhibitor maintenance with an acceptable toxicity profile. This might be a therapeutic option in this setting, sparing platinum compounds for subsequent relapse.

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.

Ovarian cancer (OC) is the second most common cause of death in women with gynecological cancer. Considering the poor prognosis, particularly in the case of platinum-resistant (PtR) disease, a huge effort was made to define new biomarkers able to help physicians in approaching and treating these challenging patients. Currently, most data can be obtained from tumor biopsy samples, but this is not always available and implies a surgical procedure. On the other hand, circulating biomarkers are detected with non-invasive methods, although this might require expensive techniques. Given the fervent hope in their value, here we focused on the most studied circulating biomarkers that could play a role in PtR OC.

OBJECTIVES: Olaparib is approved as maintenance therapy in patients with BRCA mutated platinum sensitive (PS) recurrent ovarian cancer (OC) after response to last platinum based therapy. Few data are available regarding the use out of the registration trials and on response to further treatments after progression. MATERIALS AD METHODS: In this non interventional, retrospective study, patients treated with olaparib in 13 centers, according to the label, have been collected and analyzed. Primary objectives of the study are to describe effectiveness and safety of olaparib in a real world setting with a focus on post progression treatments and response. RESULTS: 234 patients were analyzed. All patients were BRCA mutated and most of them had germline mutations. Around 50% of the patients received olaparib after 3 or more lines of platinum based chemotherapy achieving a radiologic complete (CR) or partial response. 12.4% patients with stable disease were also included. Median PFS was 14.7 months (95% CI:12.6-18), with statistically longer PFS in patients with normal serum Ca125 at baseline, a CR after last platinum based therapy and that received olaparib after second platinum based therapy. Median OS was not reached. Most frequent G3-G4 toxicity was anaemia (6%) with dose discontinuation and dose reduction in 11 (4.7%) and 49 (20.9%) of cases, respectively. Among 66 patients receiving further treatment after olaparib progression and evaluable for response, ORR was 22.2, 11.1% and 9.5% in patients with Platinum Free interval (PFI) of more than 12 months, between 6 and 12 months and less than 6 months, respectively. CONCLUSIONS: Olaparib is effective and safe in real world setting. Data on post-progression treatments seem to suggest cross resistance with chemotherapy and need to be confirmed in larger studies because of the potential importance in clinical practice decisions.

Endometriosis is a chronic, estrogen-dependent, inflammatory disease that mainly affects women of reproductive age and is defined by the presence of endometrial glands and stroma at ectopic sites. Spontaneous hemoperitoneum due to bleeding of pelvic endometriotic foci represents a very rare and severe complication of endometriosis, although most cases described in literature regard pregnant women. We hereby present a case of a severe hemoperitoneum in a non-pregnant, 42 years old woman, under dienogest therapy for deep endometriosis. This life-threatening condition was promptly managed by performing an exploratory laparoscopy where the source of bleeding was found and hemostasis successfully achieved.Bleeding from pelvic endometriotic foci ought to be considered in the differential diagnosis of gynecological causes of acute abdomen and hemoperitoneum, even under medical therapy.

OBJECTIVE: To evaluate hematologic adverse effect profiles associated with frontline platinum-based chemotherapy in ovarian cancer patients according to BRCA 1/2 mutational status. METHODS: Patients with high-grade serous ovarian cancer and a known BRCA mutational status who received in frontline 6â¯cycles of Carboplatin (AUC 5) plus Paclitaxel 175â¯mg/mq were retrospectively selected from our databases. Hematologic toxicity profiles of BRCA mutated patients were compared to non-mutated patients, according to EORTC Common Terminology Criteria for Adverse Events (CTCAE_4.02). RESULTS: Totally, 176 women of whom 58 (33%) were BRCA1/2 mutation carriers - 40 BRCA1 (69%) and 18 (31%) BRCA2 mutations carriers - and 118 (67%) non-carriers were identified. A significant higher frequency of thrombocytopenia (24% vs 5%; pâ¯<â¯0.001), anemia (21% vs 7%; pâ¯=â¯0.006) and neutropenia (62% vs 27%; pâ¯≤0.001) was observed in BRCA mutated patients, resulting in a higher percentage of granulocyte-colony stimulating growth factors injection (12% versus 1%, pâ¯<â¯0.001) and dose delay (19% versus 27%, pâ¯=â¯0.005). The multivariate analysis confirmed that granulocyte-colony stimulating growth factors injection and dose delay were statistically significantly more frequent in BRCA mutated patients (OR 2.567, 95% CI 1.136-5.798, pâ¯=â¯0.035; OR 3.860, 95% CI 1.098-13.570, pâ¯=â¯0.023). Finally, the total number of hematologic adverse events compared between the two groups of patients during the entire treatment period showed a substantial higher rate of hematologic adverse events in BRCA mutated population. CONCLUSIONS: Germline BRCA 1/2 mutations are associated with a higher hematologic toxicity in patients with ovarian cancer who underwent platinum-based chemotherapy.

OBJECTIVE: The aim of this study was to assess the efficacy and tolerability of trabectedin given every 10 days as a single agent in recurrent ovarian cancer after 3 prior regimens. METHOD: Trabectedin 0.6 mg/m2 was administered as a 3-h infusion every 10 days on a 21-day cycle. The study population was compared to patients treated with weekly paclitaxel 80 mg/m2 intravenously on days 1, 8, 15, and 22 every 4 weeks. RESULTS: We identified 34 patients previously submitted to at least 3 lines of chemotherapy who received single-agent trabectedin between 2010 and 2015. They were matched with a historical series of 34 patients who received weekly paclitaxel. No significant differences in response rate were found. Median progression-free survival was 4 months; 5 months in the trabectedin group and 4 months in the paclitaxel group. Overall survival (OS) was 13 months for the trabectedin group and 7 months for the paclitaxel group (p = 0.015). Patients who received platinum after trabectedin had a significant OS increase compared to those who received platinum after paclitaxel (18 vs. 9 months, respectively; p = 0.009). The most frequent drug-related grade 3/4 toxicities were reversible hepatic toxicity, neutropenia, anemia, thrombocytopenia, and gastrointestinal toxicity. CONCLUSION: Single-agent trabectedin every 10 days is an active treatment with a manageable toxicity profile in heavily pretreated advanced relapsed ovarian cancer patients.

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.

PURPOSE: A practice synthesis of available evidence-based medicine data in ovarian cancer (OC), aiming to provide directions for future research. MATERIALS AND METHODS: We performed a systematic review. PubMed was searched for relevant OC trials between January 2000 and December 2019. RESULTS: Out of 865 references screened, 199 trials were found eligible for inclusion. Most trials were multicenter (83.9%). There was a trend reduction in the number of patients enrolled/per study over the years. Studies testing targeted/biological therapies dominated the second decade (60 trials in 2010-2019 versus 2 trials in 2000-2009). The proportion of trials with positive survival and clinical outcomes significantly increased from 23.8% in early 2000s to 54.1% in the last 5 years. Trials with histology/molecular biomarker criteria were more likely to meet progression-free survival endpoint than those without these selection criteria (69.2% versus 32.6%). CONCLUSION: This systematic review suggests a trend of increased positive studies, mainly linked to precision medicine.
RESUMEN
Although around 80% of endometrial cancers are diagnosed at early stages and present with a 5-year survival rate exceeding 95%, patients with advanced and recurrent disease show a poor prognosis and low response rates to standard chemotherapy. In the era of targeted therapy, the great advances in the understanding of programmed death-ligand 1 (PD-L1) upregulation in cancer cells, which is responsible for tumor immune escape, have contributed to the increasing interest in immune checkpoint inhibitors as a promising strategy for the treatment of several refractory solid malignancies, including endometrial cancer. Several clinical trials have investigated the efficacy and safety of immune checkpoint inhibitors in endometrial cancer, which already led to the approval of the anti-programmed cell death protein 1 (anti-PD-1) antibody pembrolizumab as a satisfactory alternative for selected patients with unresectable or metastatic disease. As the future of cancer treatment will probably rely on combination therapy strategies, currently, innovative ongoing trials are exploring the potential role of immune checkpoint inhibitors associated with chemotherapy, radiotherapy, and other targeted therapies. Moreover, further research is warranted to discover new specific biomarkers that can accurately predict the response to immunotherapy.
RESUMEN
Olaparib is currently approved in maintenance treatment of advanced ovarian cancer after response to first-line chemotherapy for breast related cancer antigens (BRCA) mutated patients. The use of this agent is based on data from SOLO1 study that observed a decreased risk of disease progression or death and a median progression-free survival about 36 months longer in case of therapy with olaparib. However, this trial recruited only patients with advanced stage ovarian cancer. The aim of this review is to retrace the available data in order to clarify the potential efficacy and feasibility of olaparib administration in newly diagnosed epithelial ovarian cancer also in early stages.
RESUMEN
INTRODUCTION: Endometrial cancer (EC) is the most common gynaecological cancer. Despite significant progress in the multimodality treatment approach, the prognosis remains poor for patients with advanced disease. Thus, there is the necessity of more effective strategies. The microtubule-stabilizing agent ixabepilone is the first drug in this new class of agents that has been approved for metastatic breast cancer treatment. Based on empiric data and on the clinical efficacy demonstrated in breast cancer, several clinical trials were proposed to define its role in EC. The aim of this review is to determine whether ixabepilone improved the clinical outcome in patients with locally advanced, recurrent or metastatic EC. AREAS COVERED: Preclinical and clinical studies of ixabepilone in endometrial cancer were analyzed and discussed. Data were obtained by searching for English peer-reviewed articles on PubMed, phase I and II studies registered on clincaltrials.gov, and related abstracts recently presented at major international congresses. EXPERT OPINION: Advanced or recurrent EC still represents a challenge and an unmet need in the panorama of gynaecological malignancies. Ixabepilone's future therapeutic role in EC remains ill defined. Nevertheless, despite its limited efficacy in EC, clinicians treating gynaecological tumours should be aware of its main aspects.

According to international guidelines, treatment of cervical cancer (CC) consists of surgery in early stages and of chemoradiation in locally advanced disease. Metastatic disease is usually treated with palliative chemotherapeutic regimens, but cytostatic drugs present significant side effects and show limited activity. Thus, the discovery of new anticancer agents, interfering with molecular targets expressed by the tumor's microenvironment or by the tumor cell itself, represents a possible chance for the struggle against this tumor. The aim of this review is to report all targets that have been investigated in preclinical and clinical studies. We discuss these potential targets according to "targeted therapies" NCI classification. The most investigated molecular targets have been epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF), both involved in CC etiopathogenesis. Studies with anti-angiogenetic agents showed encouraging clinical efficacy and acceptable toxicity. Other interesting results have been obtained by immunotherapeutic strategies. Since biological characteristics of CC, especially in recurrent disease, are still partially unknown, future studies are necessary to understand mechanisms involved in CC carcinogenesis, in order to give to patients the most tailored and efficient treatments.
