ABSTRACT

To date, there are no biomarkers that define a patient subpopulation responsive to bevacizumab (BEV), an effective treatment option for advanced ovarian carcinoma (OC). In the context of the MITO16A/MaNGO OV-2 trial, a Phase IV study of chemotherapy combined with BEV in first-line treatment of advanced OC, we evaluated TP53 mutations by next-generation sequencing and p53 expression by immunohistochemistry (IHC) on 202 and 311 cases, respectively. We further correlated TP53 mutations in terms of type, function, and site, and IHC data with patients' clinicopathological characteristics and survival. TP53 missense mutations of unknown function (named unclassified) represented the majority of variants in our population (44.4%) and were associated with a significantly improved overall survival (OS) both in univariable (hazard ratio [HR] = 0.43, 95% confidence interval [CI] = 0.20-0.92, p = .03) and multivariable analysis (HR = 0.39, 95% CI = 0.18-0.86, p = .02). Concordance between TP53 mutational analysis and IHC was 91%. We observed an HR of 0.70 for OS in patients with p53 IHC overexpression compared to p53 wild-type, which however did not reach statistical significance (p = .31, 95% CI = 0.36-1.38). Our results indicate that the presence of unclassified TP53 mutations has favorable prognostic significance in patients with OC receiving upfront BEV plus chemotherapy. In particular, unclassified missense TP53 mutations characterize a subpopulation of patients with a significant survival advantage, independently of clinicopathological characteristics. Our findings warrant future investigations to confirm the prognostic impact of TP53 mutations in BEV-treated OC patients and deserve to be assessed for their potential predictive role in future randomized clinical studies.

ABSTRACT

BACKGROUND: CA-125 alone is widely used to diagnose progressive disease (PD) in platinum-sensitive recurrent ovarian cancer (PSROC) on chemotherapy. However, there are increasing concerns regarding its accuracy. We assessed concordance between progression defined by CA-125 and RECIST using data from the CALYPSO trial. METHODS: We computed concordance rates for PD by CA-125 and RECIST to determine the positive (PPV) and negative predictive values (NPV). RESULTS: Of 769 (79%) evaluable participants, 387 had CA-125 PD, where only 276 had concordant RECIST PD (PPV 71%, 95% CI 67-76%). For 382 without CA-125 PD, 255 had RECIST PD but 127 did not (NPV 33%, 95% CI 29-38). There were significant differences in NPV according to baseline CA-125 (≤100 vs >100: 42% vs 25%, P < 0.001); non-measurable vs measurable disease (51% vs 26%, P < 0.001); and platinum-free-interval (>12 vs 6-12 months: 41% vs 14%, P < 0.001). We observed falling CA-125 levels in 78% of patients with RECIST PD and CA-125 non-PD. CONCLUSION: Approximately 2 in 3 women with PSROC have RECIST PD but not CA-125 PD by GCIG criteria. Monitoring CA-125 levels alone is not reliable for detecting PD. Further research is required to investigate the survival impact of local therapy in radiological detected early asymptomatic PD.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: There are no data, and thus no consensus, on the optimal duration of poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy for exceptional responders (here defined as progression-free for 5 years or longer) with platinum sensitive recurrent ovarian cancer. The current licence is to continue PARP inhibitors until progression or toxicity; however, international practice varies considerably. The risks of late progression and late-onset myeloid malignancies, defined as occurring beyond 5 years of PARP inhibition, are unknown. This study aims to examine the practice patterns and opinions regarding the management and surveillance protocols of exceptional responders with platinum sensitive recurrent ovarian cancer. METHODS: An online international survey of experts from June 2023 to June 2024 was carried out, disseminated at Gynaecologic Cancer Intergroup meetings and by Chairs of Cooperative Groups. RESULTS: 210 responses were received from 26 countries including Australia (27 respondents), Germany (24), the UK (21), the Netherlands (16), France (13), Spain (12), Canada (12), Italy (11), Japan (11), and other countries (63). Most respondents did not have institutional or trials group guidelines regarding duration of PARP inhibitors (154, 73.3%). For the minority with guidelines, recommendations varied: 1 year (2), 2 years (13), 3 years (4), and indefinite treatment (22). Individual practice varied considerably for those without guidelines: most (116, 76.3%) recommended ≥5 years of PARP inhibition, of which 73 (48.0%) recommended indefinite PARP inhibition. Sixty-six respondents (31.4%) reported having patients with late progression and 46 (22.0%) had cases with late-onset myeloid malignancies. Surveillance practices varied widely across all respondents. CONCLUSIONS: This international survey highlights the diverse practice variations and disparate views on the optimal duration of maintenance therapy with PARP inhibitors in platinum sensitive recurrent ovarian cancer. The responses suggest a notable risk of late progression and myelodysplastic syndrome/acute myeloid leukemia among exceptional responders which needs confirmation. Detailed individual patient data is required to draw more reliable conclusions; another study is underway addressing this.

ABSTRACT

BACKGROUND: Adding immunotherapy to first-line chemotherapy might improve outcomes for patients with advanced or recurrent endometrial cancer. We aimed to compare carboplatin and paclitaxel versus avelumab plus carboplatin and paclitaxel as first-line treatment with avelumab given concurrent to chemotherapy and as maintenance after the end of chemotherapy. METHODS: MITO END-3 is an open-label, randomised, controlled, phase 2 trial conducted at 31 cancer institutes, hospitals, and universities in Italy. Eligible patients were aged 18 years or older with histologically confirmed advanced (FIGO stage III-IV) or recurrent endometrial cancer, an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, and no previous systemic anticancer therapy as primary treatment for advanced or metastatic disease. Participants were randomly assigned (1:1) using a computerised minimisation procedure stratified by centre, histology, and stage at study entry, to either receive carboplatin (area under the curve [AUC] 5 mg/mL × min) and paclitaxel (175 mg/m2; standard group) intravenously every 3 weeks for six to eight cycles or avelumab (10 mg/kg intravenously) added to carboplatin and paclitaxel (experimental group) every 3 weeks and then every 2 weeks as a single maintenance treatment after the end of chemotherapy until disease progression or unacceptable toxicity. Patients, treating clinicians, and those assessing radiological examinations were not masked to study treatment. The primary endpoint was investigator-assessed progression-free survival, measured in the intention-to-treat (ITT) population. Patients who received at least one dose of study drug were included in the safety analysis. Experimental group superiority was tested with 80% power and one-tailed α 0·20. This trial is registered with ClinicalTrials.gov (NCT03503786) and EudraCT (2016-004403-31). FINDINGS: From April 9, 2018, to May 13, 2021, 166 women were assessed for eligibility and 39 were excluded. 125 eligible patients were randomly assigned to receive carboplatin and paclitaxel (n=62) or avelumab plus carboplatin and paclitaxel (n=63) and included in the ITT population. The median follow-up was 23·3 months (IQR 13·2-29·6) and was similar between the two groups. 91 progression-free survival events were reported, with 49 events in 62 patients in the standard group and 42 events in 63 patients in the experimental group. The median progression-free survival was 9·9 months (95% CI 6·7-12·1) in the standard group and 9·6 months (7·2-17·7) in the experimental group (HR of progression or death 0·78 [60% CI 0·65-0·93]; one-tailed p=0·085). Serious adverse events were reported more frequently in the experimental group (24 vs seven events in the standard group); neutrophil count decrease was the most frequent grade 3-4 adverse event (19 [31%] of 61 patients in the experimental group vs 26 [43%] of 61 patients in the standard group). Two deaths occurred in the experimental group during treatment (one respiratory failure following severe myositis [possibly related to treatment] and one cardiac arrest [not related to treatment]). INTERPRETATION: Adding avelumab to first-line chemotherapy deserves further testing in patients with advanced or recurrent endometrial cancer, although consideration of mismatch repair status is warranted. FUNDING: Pfizer.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Standard treatment of newly diagnosed, advanced ovarian carcinoma (OC) consists of cytoreductive surgery followed by platinum-based chemotherapy with or without bevacizumab. Maintenance therapy with PARP inhibitors and olaparib-bevacizumab has recently shown to significantly improve progression-free survival in the first-line setting. Some practical aspects of maintenance therapy, however, are still poorly defined. AIM OF THE STUDY: To provide guidance to clinicians in the selection of maintenance therapy for newly diagnosed, advanced ovarian carcinoma. METHODS: A board of six gynecologic oncologists with expertise in the treatment of OC in Italy convened to address issues related to the new options for maintenance treatment. Based on scientific evidences, the board produced practice-oriented statements. Consensus was reached via a modified Delphi study that involved a panel of 22 experts from across Italy. RESULTS: Twenty-seven evidence- and consensus-based statements are presented, covering the following areas of interest: use of biomarkers (BRCA mutations and presence of homologous recombination deficiency); timing and outcomes of surgery; selection of patients eligible for bevacizumab; definition of response to treatment; toxicity and contraindications; evidence of synergy of bevacizumab plus PARP inhibitor. Two treatment algorithms are also included, for selecting maintenance therapy based on timing and outcomes of surgery, response to platinum-based chemotherapy and biomarker status. A score for the assessment of response to chemotherapy is proposed, but its validation is ongoing. CONCLUSIONS: We provide here consensus statements and treatment algorithms to guide clinicians in the selection of appropriate and personalized maintenance therapy in the first-line setting of advanced OC management.

ABSTRACT

Numerous disease- and patient-related factors must be considered when selecting systemic therapy for recurrent ovarian cancer. Anti-angiogenics (bevacizumab) and poly(ADP-ribose) polymerase inhibitors (olaparib, niraparib and rucaparib) have an important role as maintenance of platinum-based chemotherapy for recurrent disease and their use in the first-line setting of advanced-stage disease is becoming established. As previous exposure to none, one or both of these drug classes is integral to selecting next therapy, front-line use impacts on options available to treat recurrent disease. A key strategy to delay platinum resistance and improve prognosis of recurrent disease is to alternate treatments with different mechanisms of action. The multiple mechanisms of trabectedin and its complementarity with platinum allow intercalation between platinum regimens in potentially platinum-responsive patients with recurrent disease.

ABSTRACT

BACKGROUND: Chemotherapy with carboplatin, paclitaxel, and bevacizumab is the standard therapy for patients with advanced stage ovarian cancer wild-type BRCA after primary surgery. The most frequent side effects of bevacizumab in this setting are hypertension, thrombosis, hemorrhage, and proteinuria, while arthralgia has been poorly described. OBJECTIVE: To examine the incidence, duration, and reversibility of arthralgia. PATIENTS AND METHODS: A retrospective analysis was performed to describe the occurrence and outcome of arthralgia in 114 patients with advanced ovarian cancer, given first-line treatment with a combination of carboplatin, paclitaxel, and bevacizumab. Statistical analysis was performed to investigate a possible prognostic role of arthralgia, with progression-free survival as endpoint. RESULTS: 47 of 114 patients (41%) developed arthralgia during therapy. All patients had grade 1 or grade 2 arthralgia. Toxicity persisted after the end of bevacizumab in 17/47 patients (36%). Median progression-free survival for patients without arthralgia was 18 months (95% CI 14 to 24) compared with 29 months (95% CI 21 to not reached) for patients experiencing arthralgia (p=0.03). In order to avoid possible biases related to treatment duration, a multivariable Cox proportional hazards model including toxicity as a time dependent variable and age, stage, and residual disease after primary surgery was performed. In this model no variable showed a statistically significant association with progression-free survival. CONCLUSION: A high incidence of arthralgia (41%) was found and although rogression-free survival was worse for those patients who developed arthralgia, this was not maintained on multivariate analysis. Guidelines for treatment of this adverse event are needed.

ABSTRACT

INTRODUCTION: The role of cytoreductive surgery in the poly-ADP ribose polymerase inhibitors era is not fully investigated. We evaluated the impact of surgery performed prior to platinum-based chemotherapy followed by olaparib maintenance in platinum-sensitive BRCA-mutated recurrent ovarian cancer. METHODS: This retrospective study included platinum-sensitive recurrent ovarian cancer BRCA-mutated patients from 13 Multicenter Italian Trials in Ovarian cancer and gynecological malignancies centers treated between September 2015 and May 2019. The primary outcomes were progression-free survival and overall survival. Data on post-progression treatment was also assessed. RESULTS: Among 209 patients, 72 patients (34.5%) underwent cytoreductive surgery followed by platinum-based chemotherapy and olaparib maintenance, while 137 patients (65.5%) underwent chemotherapy treatment alone. After a median follow-up of 37.3 months (95% CI: 33.4 to 40.8), median progression-free survival in the surgery group was not reached, compared with 11 months in patients receiving chemotherapy alone (P<0.001). Median overall survival was nearly double in patients undergoing surgery before chemotherapy (55 vs 28 months, P<0.001). Post-progression therapy was assessed in 127 patients: response rate to chemotherapy was 29.2%, 8.8%, and 9.0% in patients with platinum-free interval >12 months, between 6 and 12 months, and <6 months, respectively. CONCLUSION: Cytoreductive surgery performed before platinum therapy and olaparib maintenance was associated with longer progression-free survival and overall survival in BRCA-mutated platinum-sensitive relapsed ovarian cancer patients. In accordance with our preliminary results, the response rate to chemotherapy given after progression during olaparib was associated with platinum-free interval.

ABSTRACT

OBJECTIVE: To explore the clinical and biological prognostic factors for advanced ovarian cancer patients receiving first-line treatment with carboplatin, paclitaxel, and bevacizumab. METHODS: A multicenter, phase IV, single arm trial was performed. Patients with advanced (FIGO (International Federation of Gynecology and Obstetrics) stage IIIB-IV) or recurrent, previously untreated, ovarian cancer received carboplatin (AUC (area under the curve) 5), paclitaxel (175 mg/m2) plus bevacizumab (15 mg/kg) on day 1 for six 3-weekly cycles followed by bevacizumab single agent (15 mg/kg) until progression or unacceptable toxicity up to a maximum of 22 total cycles. Here we report the final analysis on the role of clinical prognostic factors. The study had 80% power with a two-tailed 0.01 α error to detect a 0.60 hazard ratio with a factor expressed in at least 20% of the population. Both progression-free and overall survival were used as endpoints. RESULTS: From October 2012 to November 2014, 398 eligible patients were treated. After a median follow-up of 32.3 months (IQR 24.1-40.4), median progression-free survival was 20.8 months (95% CI 19.1 to 22.0) and median overall survival was 41.1 months (95% CI 39.1 to 43.5). Clinical factors significantly predicting progression-free and overall survival were performance status, stage, and residual disease after primary surgery. Neither baseline blood pressure/antihypertensive treatment nor the development of hypertension during bevacizumab were prognostic. There were two deaths possibly related to treatment, but no unexpected safety signal was reported. CONCLUSIONS: Efficacy and safety of bevacizumab in combination with carboplatin and paclitaxel and as maintenance were comparable to previous data. Hypertension, either at baseline or developed during treatment, was not prognostic. Performance status, stage, and residual disease after primary surgery remain the most important clinical prognostic factors. TRIAL REGISTRATION NUMBER: EudraCT 2012-003043-29; NCT01706120.

ABSTRACT

INTRODUCTION: The use of routine antithrombotic prophylaxis is not recommended for advanced cancer patients receiving chemotherapy. The effect of bevacizumab-containing therapy on the risk of thromboembolic events remains controversial in ovarian cancer patients. We report on the incidence of thromboembolic events and the prevalence of antithrombotic therapy in patients enrolled in the single arm, phase IV, MITO-16A/MaNGO-OV2A trial. METHODS: In this trial, potential prognostic factors for patients with previously untreated ovarian cancer receiving a combination of platinum-based chemotherapy and bevacizumab were explored and the final analysis has already been reported. In this secondary analysis, the occurrence of thromboembolic events and the use of antithrombotic therapy were described according to the clinical characteristics of the patients. The prognostic role of thromboembolic events for progression-free and overall survival were also evaluated. RESULTS: From October 2012 to November 2014, 398 eligible patients were enrolled. 76 patients (19.1%) were receiving some type of anticoagulant or anti-aggregant treatment at baseline. Overall, 24 thromboembolic events were reported (cumulative incidence of 6.0%). The occurrence of thromboembolic events was not associated with baseline patient characteristics and was not modified by the use of antithrombotic prophylaxis (HR 0.60, 95% CI 0.18 to 2.0). Occurrence of thromboembolic events was not associated with progression-free survival (HR 1.34, 95% CI 0.83 to 2.15) or overall survival (HR 0.78, 95% CI 0.37 to 1.61). CONCLUSIONS: In our study, a 6.0% rate of thromboembolic events was reported during treatment with bevacizumab plus chemotherapy. Thromboembolic events were not associated with the clinical characteristics of the patients or with the use of antithrombotic prophylaxis, nor did they significantly affect the long-term prognosis.

ABSTRACT

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.

ABSTRACT

Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved as maintenance therapy of recurrent ovarian cancer (OC) patients with a BRCA mutation. To achieve the maximum clinical benefit, adherence to olaparib must be persistent. However, in clinical practice, this is challenged by the frequent suboptimal management of toxicities. In view of the expanding use of olaparib also in Italy, physicians must learn how to adequately and promptly manage drug toxicities not to unnecessarily interrupt or reduce the dose. The experts agreed that nausea,vomiting, anemia, and fatigue are the most frequent events experienced by OC patients on olaparib, and that these toxicities usually develop early during treatment, are mainly of grade 1-2 and transient and can be managed with simple non-pharmacological interventions. By sharing their real-world experiences, the panel prepared, for each toxicity, an algorithm organized by grade and besides the procedures indicated in the local label, included supportive care interventions based also on nutritional and lifestyle modifications and psycho-oncology consultation. Moreover, in view of the tablet entry into the Italian market, the full and reduced dosages of capsules and tablets were compared. This practical guidance is intended to be a tool to support especially less-experienced physicians in the management of these complex patients, with the aim to help preventing the worsening of patients' conditions and the unnecessary interruption/reduction of olaparib dosage, which may jeopardize treatment efficacy.

ABSTRACT

The majority of patients with advanced ovarian cancer progress after first-line therapy and require further treatment. Tumor biology, prior chemotherapy, responses to previous therapy, performance status, and toxicity are the characteristics that influence treatment choice. These criteria have been linked to the time between relapse and last platinum therapy: the platinum-free interval. Today, patients are classified as either those who are eligible for a new platinum-based therapy or those for whom platinum is not an option. A nonplatinum regimen should be administered to patients who are not candidates for platinum re-treatment. This group includes patients with early relapse after, or progression during, previous platinum-based chemotherapy and patients with platinum intolerability. A single agent such as weekly paclitaxel, pegylated liposomal doxorubicin (PLD), gemcitabine, or topotecan represents the standard. For patients not treated with bevacizumab in the first line, this drug should be added to chemotherapy. For patients for whom platinum rechallenge is an option (because they are potentially platinum-responsive), different strategies are available with the incorporation of biological drugs targeting angiogenesis or the mechanisms of DNA repair. A BRCA mutation status predicts a better response to platinum and poly(adenosine diphosphate-ribose) polymerase (PARP) inhibition. PARP inhibitors and antiangiogenic drugs have proven efficacy as maintenance therapy after chemotherapy and concurrently with chemotherapy, respectively. These agents have changed current practice, although few biomarkers are available to guide decisions. Patients potentially responsive to platinum who cannot receive the drug again can be treated with a combination of trabectedin and PLD, the most active nonplatinum therapy in this setting.

ABSTRACT

BACKGROUND: Cervical cancer cells often express Epidermal Growth Factor Receptor (EGFR). Cetuximab (CET), an anti-EGFR antibody, can be safely combined with carboplatin (C) and paclitaxel (P), a standard treatment for advanced/recurrent cervical cancer (ARCC) patients. PATIENTS AND METHODS: ARCC patients, ECOG PS ≤ 1, were randomized to CP for 6 cycles with or without CET (400 mg/m2 one week before starting CP, then 250 mg/m2 weekly) until disease progression or unacceptable toxicity. Event-free survival (EFS) was the primary endpoint. With a 4.5 months expected median EFS and a 6.4 months predicted EFS (HR 0.70), 0.20 one-tailed α and 80% power, 89 events were required for the final intent-to-treat analysis. RESULTS: 108 patients were assigned to CP (n = 53) or CP-CET (n = 55). Median age was 50, 69% were PS0, 76% had recurrent disease, 91% had distant metastasis and 57% had received previous chemotherapy. After a median follow-up of 23 months, 102 patients had an event, 97 progressed and 61 died. Median EFS was 4.7 and 6.0 months (one-tail P = 0.43), median PFS was 5.2 and 7.6 months (one-tail P = 0.20) and median OS was 17.7 and 17 months (one-tail P = 0.27), with CP and CP-CET, respectively. There was no difference in the occurrence of severe adverse events, except for skin toxicity. Biomarker analysis, in a small subgroup of patients, suggests that PIK3CA mutation might be predictive of CET resistance. CONCLUSION: CP-CET was not more active than CP alone in unselected ARCC patients.

ABSTRACT

The MITO 15 was a prospective, single-arm trial, evaluating trabectedin monotherapy in patients with recurrent ovarian cancer (OC) who were BRCA mutation-carriers or had a BRCAness phenotype. It is largely reported that trabectedin may induce nausea and vomiting but the real emetogenic potential of the drug, in the different schedules, has never been fully described; furthermore, OC patients are known to have an enhanced risk of developing nausea and vomiting due to female gender, abdominal spreading of the disease, and major surgery experienced by most of them. We thought to carry on a sub-study in the MITO 15 context focused on chemotherapy-induced nausea and vomiting (CINV) associated with trabectedin single agent. For all patients enrolled in the trial, we evaluated the antiemetic regimen at the first cycle, acute and delayed CINV, any rescue therapy, any change in the prophylactic antiemetic regimen, and the potential relationship between dexamethasone dosage and incidence of CINV. Overall, our findings were consistent with literature and confirmed that trabectedin can be classified as moderately emetogenic. We observed slightly higher rates of both nausea and vomiting compared to previous experiences with trabectedin monotherapy, probably due to intrinsic features of our population: all females and suffering from ovarian cancer. It seems that in preventing acute CINV, the combination of three drugs was more effective than the doublet; however, the difference did not reach statistical significance; further studies are required to verify such hypothesis. Given the extreme heterogeneity of the antiemetic regimens used, it appears that a standard antiemetic protocol does not exist and more specific guidelines for clinicians are needed.

ABSTRACT

OBJECTIVE: The aim of this study was to analyze the long-term toxicity and quality of life (QOL) in patients with locally advanced cervical cancer (LACC) treated with chemoradiation [chemotherapy/radiotherapy (CT/RT)] or neoadjuvant CT (NACT) followed by radical surgery (RS). METHODS: Fifty-nine patients with LACC in remission after treatment with NACT + RS (n = 34) or CT/RT (n = 25) were interviewed with an Incontinence Impact Questionnaire (IIQ-7), a Quality of Life Questionnaire (EORTC QLQ-C30), and a Quality of Life Questionnaire for Cervical Cancer (EORTC QLQ-CX24) to compare long-term toxicity and QOL. RESULTS: The mean age was 53 ± 9.8 and 59 ± 11.5 years in the NACT + RS and CT/RT groups, respectively. Overall, diarrhea and constipation were reported in 15 and 68%, respectively, while bladder complaints and a low level of sexual enjoyment were reported in 36 and 47%, respectively. The NACT + RS patients showed a worse sexual activity (74.71 ± 33.57 vs. 92.06 ± 17.96; p = 0.019) and sexual enjoyment (71.21 ± 23.67 vs. 88.88 ± 21.71; p = 0.040) and more frequently complained of constipation (49.01 ± 34.06 vs. 26.66 ± 31.66; p = 0.013), while CT/RT patients more frequently suffered from diarrhea (1.96 ± 7.96 vs. 14.66 ± 28.40; p = 0.017). CONCLUSIONS: Many patients treated for LACC have long-term complaints regarding sexual activity and bladder and bowel function. The majority of QOL aspects were similar in the two groups at long-term follow-up. However, diarrhea was more frequent and severe in CT/RT patients, while constipation was more frequent and severe in NACT + RS patients, and they showed a worse sexual life perception. Larger randomized trials addressing these issues are needed.

ABSTRACT

Ovarian cancer remains a major issue for gynecological oncologists, and most patients are diagnosed when the disease is already advanced with a poor chance of survival. Debulking surgery followed by platinum-taxane chemotherapy is the current standard of care, but based on several different strategies currently under evaluation, some encouraging data have been published in the last 4 to 5 years. This review provides a state-of-the-art overview of the available alternatives to conventional treatment and the most promising new combinations. For example, neoadjuvant chemotherapy does not seem to be inferior to primary debulking. Despite its outcome improvements, intraperitoneal chemotherapy struggles for acceptance due to the heavy toxicity. Dose-dense chemotherapy, after showing an impressive efficacy in Asian populations, has not produced equal results in a European cohort, and the results of alternative platinum doublets are not superior to those of carboplatin and paclitaxel. In this setting, adherence to a maintenance therapy after first-line treatment and multiple (primarily antiangiogenic) agents appears to be effective. Although many questions, including the duration of maintenance treatment and the use of bevacizumab beyond progression, remain unanswered, new biologic agents, such as poly(ADP-ribose) polymerase (PARP) inhibitors, nintedanib, and mitogen-activated protein/extracellular signal-regulated kinase (MEK) inhibitors, have emerged as potential therapeutic options in the very near future. Based on the multiplicity of available strategies, the histological and molecular features of the tumor, in addition to patient's clinical condition and disease state, continue to gain importance in guiding treatment choices.
