Primary results of the AGO-Zervix-1 Study: A prospective, randomized phase III study to compare the effects of paclitaxel and topotecan with those of cisplatin and topotecan in the treatment of patients with recurrent and persistent cervical cancer

BACKGROUND

Before the era of immunotherapies and antibody-drug conjugates, there were limited chemotherapeutic options for patients with recurrent and metastatic cervical cancer. Combination therapies with cisplatin have shown some superiority over monotherapy. This study examined platinum-free treatment regimens, comparing a combination of topotecan and paclitaxel (TP) with topotecan and cisplatin (TC) in patients with recurrent or metastatic cervical cancer, with or without prior platinum-based treatment.

METHODS

The AGO-Zervix-1 Study (NCT01405235) is a prospective, randomized phase III study in which patients were randomly assigned at a 1:1 ratio to treatment within the control arm with topotecan (0.75 mg/m2) on days 1-3 and cisplatin (50 mg/m2) on day 1 every 3 weeks and in the study arm topotecan (1.75 mg/m2) and paclitaxel (70 mg/m2) on days 1, 8, and 15 every 4 weeks or treatment. The primary study aim was overall survival; progression-free survival, toxicity, and quality of life were secondary aims. The interim and final analysis is here reported after recruitment of 173 of 312 planned patients.

RESULTS

Median overall survival in the TP arm was 9.6 months, compared with 12.0 months in the TC arm (log-rank test, P = 0.33). Median progression-free survival rates were 4.4 months with TP and 4.2 months with TC (log-rank test, P = 0.47). Leukopenia and nausea/vomiting were more frequent in the cisplatin-containing arm. Otherwise, toxicity profiles were comparable. There were no differences in FACT-G-assessed quality of life.

CONCLUSION

Platinum-based combination chemotherapy remains the standard of care chemotherapy regimen for patients with recurrent or metastatic cervical cancer.

Topical imiquimod compared with conization to treat cervical high-grade squamous intraepithelial lesions: Multicenter, randomized controlled trial

OBJECTIVE

In a previous phase II trial, we showed that topical imiquimod (IMQ) therapy is an efficacious treatment for high-grade squamous intraepithelial lesion (HSIL). Aim of the present study was to investigate the non-inferiority of a 16-week topical, self-applied IMQ therapy compared to large loop excision of the transformation zone (LLETZ) in patients diagnosed with HSIL.

METHODS

Phase III randomized, controlled, multicenter, open trial performed by Austrian Gynecologic Oncology group. Patients with histologically proven cervical intraepithelial neoplasia (CIN)2 (30 years and older) or CIN3 (18 years and older) and satisfactory colposcopy were randomized to topical IMQ treatment or LLETZ. Successful treatment was defined as negative HPV high-risk test result 6 months after start of the treatment. Secondary endpoints were histological outcome and HPV clearance rates.

RESULTS

Within 3 years 93 patients were randomized, received the allocated treatment and were available for ITT analysis. In the IMQ group negative HPV test at 6 months after treatment start was observed in 22/51 (43.1%) of patients compared to 27/42 (64.3%) in the LLETZ group on ITT analysis (rate difference 21.2%-points, 95% two-sided CI: 0.8 to 39.1). In the IMQ group histologic regression 6 months after treatment was observed in 32/51 (63%) of patients and complete histologic remission was observed in 19/51 (37%) of patients. Complete surgical resection was observed in 84% after LLETZ.

CONCLUSION

In women with HSIL, IMQ treatment results in lower HPV clearance rates when compared to LLETZ. LLETZ remains the standard for women with HSIL when treatment is required.

Austria-based real-world data on bevacizumab in newly diagnosed epithelial ovarian cancer

Background

Front-line maintenance therapy with bevacizumab demonstrates high efficacy and safety in epithelial ovarian cancer, as already shown in large phase III trials; however, the corresponding study populations are often not fully representative of patients in clinical routine. In this Austria-based multicenter study, we aimed to explore the real-world outcomes of bevacizumab use in front-line treatment of ovarian cancer, including patients with comorbidities and poor performance status.

Patients

This study is an open label single arm multicenter noninterventional trial and included patients with newly diagnosed advanced epithelial ovarian cancer, who were treated with platinum-based chemotherapy and were candidates for receiving bevacizumab according to the product label. Data collection started in the third quarter of 2012 and ended in the third quarter of 2018.

Results

In this study 50 patients were included and 575 adverse events were reported for 90% of the patients. The majority of the adverse events were mild (47%) or moderate (37%). The most common adverse events were hypertension (60%), anemia (48%), leukopenia (42%), thrombocytopenia (36%), neutropenia (36%) and proteinuria (26%). A relation to bevacizumab was documented only for 10.3% of all adverse events. In almost 50% of all adverse events, no intervention was needed and bevacizumab treatment had to be interrupted only in 3.3% of all adverse events. The median progression-free survival was 1.3 years (95% CI 1.1–1.8).

Conclusion

The routine use of front-line bevacizumab for advanced ovarian cancer is associated with high efficacy comparable with that obtained in randomized phase III clinical trials; however, hypertension and proteinuria were reported significantly more often in our Austria-based real-world population.

The Pretreatment Controlling Nutritional Status Score in Ovarian Cancer: Influence on Prognosis, Surgical Outcome, and Postoperative Complication Rate

Introduction The Controlling Nutritional (CONUT) Status score is an established predictor of impaired prognosis in patients with solid tumors. The aim of this study was to investigate the prognostic value of the CONUT score for overall survival and perioperative complication rates in patients with epithelial ovarian cancer.

Patients In this retrospective study we assessed the data of 337 consecutive patients with ovarian cancer. The CONUT score was associated with surgical outcome, postoperative complications and clinicopathological parameters. We used univariate log-rank test and multivariable Cox regression models to evaluate the association between pretreatment CONUT scores and survival.

Results A low CONUT score (0 – 2) was associated with an early FIGO stage (p = 0.004), complete tumor resection (p < 0.001), less neoadjuvant chemotherapy (p = 0.017) and other histologies than serous cystadenocarcinoma (p = 0.006). Postoperative complications were observed in 51.4% and 60.5% of patients with a CONUT score of 0 – 2 and a score > 2, respectively (p = 0.161). A shorter overall survival was observed in patients with a CONUT score > 2 compared to patients with a low CONUT score, with 5-year overall survival rates of 31.5% and 58.7%, respectively (p < 0.001). In multivariable analysis, both advanced age (p < 0.001) and FIGO stage (p < 0.001), residual disease (p < 0.001) and a high CONUT score (p = 0.048) were independently associated with unfavorable overall survival.

Conclusion Pretreatment CONUT score is an independent prognostic marker for overall survival and associated with successful surgery. Patients with a high CONUT score might benefit from pretreatment nutritional intervention.

Randomized Trial of Cytoreductive Surgery for Relapsed Ovarian Cancer

BACKGROUND

Treatment for patients with recurrent ovarian cancer has been mainly based on systemic therapy. The role of secondary cytoreductive surgery is unclear.

METHODS

We randomly assigned patients with recurrent ovarian cancer who had a first relapse after a platinum-free interval (an interval during which no platinum-based chemotherapy was used) of 6 months or more to undergo secondary cytoreductive surgery and then receive platinum-based chemotherapy or to receive platinum-based chemotherapy alone. Patients were eligible if they presented with a positive Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) score, defined as an Eastern Cooperative Oncology Group performance-status score of 0 (on a 5-point scale, with higher scores indicating greater disability), ascites of less than 500 ml, and complete resection at initial surgery. A positive AGO score is used to identify patients in whom a complete resection might be achieved. The primary end point was overall survival. We also assessed quality of life and prognostic factors for survival.

RESULTS

A total of 407 patients underwent randomization: 206 were assigned to cytoreductive surgery and chemotherapy, and 201 to chemotherapy alone. A complete resection was achieved in 75.5% of the patients in the surgery group who underwent the procedure. The median overall survival was 53.7 months in the surgery group and 46.0 months in the no-surgery group (hazard ratio for death, 0.75; 95% confidence interval, 0.59 to 0.96; P = 0.02). Patients with a complete resection had the most favorable outcome, with a median overall survival of 61.9 months. A benefit from surgery was seen in all analyses in subgroups according to prognostic factors. Quality-of-life measures through 1 year of follow-up did not differ between the two groups, and we observed no perioperative mortality within 30 days after surgery.

CONCLUSIONS

In women with recurrent ovarian cancer, cytoreductive surgery followed by chemotherapy resulted in longer overall survival than chemotherapy alone. (Funded by the AGO Study Group and others; DESKTOP III ClinicalTrials.gov number, NCT01166737.).

•Checkpoint inhibitor therapy affecting PD-L1 as treatment for advanced solid tumors.•Success in trial pembrolizumab therapy in multiresistant metastatic choriocarcinoma.•Long-term remission after pembrolizumab therapy in multiresistant choriocarcinoma.•Only six reported cases, one with comparable follow-up and outcome.

The Long-Term Prognostic Significance of Circulating Tumor Cells in Ovarian Cancer-A Study of the OVCAD Consortium

INTRODUCTION

We previously reported the prognostic impact of circulating tumor cells (CTCs) in a multicenter study on minimal residual disease in primary ovarian cancer. With additional follow-up data, we evaluated the combined CTC approach (CTCs^combo), in particular for the patients who had survived more than five years.

MATERIAL AND METHODS

Blood samples taken at baseline and six months after adjuvant treatment (follow-up) were assessed by quantitative PCR (qPCR) measuring PPIC transcripts and immunofluorescent staining (IF). A positive result with either IF or qPCR was classified as CTC^combo-positive. Further, PPIC was assessed in the primary tumor tissue.

RESULTS

The concordance of IF and qPCR was 65% at baseline and 83% after treatment. Results showed that 50.5% of the baseline and 29.5% of the follow-up samples were CTC^combo-positive. CTCs^combo after treatment were associated with increased mortality after adjusting for FIGO stage (HR 2.574, 95% CI: 1.227-5.398, p = 0.012), a higher risk of recurrence after adjusting for peritoneal carcinosis (HR 4.068, 95% CI: 1.948-8.498, p < 0.001), and increased mortality after five survived years.

DISCUSSION

The two-sided analytical approach revealed CTC subpopulations associated with ovarian cancer progression and may illuminate a potential treatment-related shift in molecular phenotypes. That approach can identify patients who have elevated risk of recurrence and death due to ovarian cancer and who may require risk-adapted treatment strategies.

Risk Reclassification of Patients with Endometrial Cancer Based on Tumor Molecular Profiling: First Real World Data

Recently, guidelines for endometrial cancer (EC) were released that guide treatment decisions according to the tumors’ molecular profiles. To date, no real-world data regarding the clinical feasibility of molecular profiling have been released. This retrospective, monocentric study investigated the clinical feasibility of molecular profiling and its potential impact on treatment decisions. Tumor specimens underwent molecular profiling (testing for genetic alterations, (immune-)histological examination of lymphovascular space invasion (LVSI), and L1CAM) as part of the clinical routine and were classified according to the European Society for Medical Oncology (ESMO) classification system and to an integrated molecular risk stratification. Shifts between risk groups and potential treatment alterations are described. A total of 60 cases were included, of which twelve were excluded (20%), and eight of the remaining 48 were not characterized (drop-out rate of 16.7%). Molecular profiling revealed 4, 6, 25, and 5 patients with DNA polymerase-epsilon mutation, microsatellite instability, no specific molecular profile, and TP53 mutation, respectively. Three patients had substantial LVSI, and four patients showed high L1CAM expression. Molecular profiling took a median of 18.5 days. Substantial shifts occurred between the classification systems: four patients were upstaged, and 19 patients were downstaged. Molecular profiling of EC specimens is feasible in a daily routine, and new risk classification systems will change treatment decisions substantially.

Olaparib plus bevacizumab as maintenance therapy in patients with newly diagnosed, advanced ovarian cancer: Japan subset from the PAOLA-1/ENGOT-ov25 trial

OBJECTIVE

The addition of maintenance olaparib to bevacizumab demonstrated a significant progression-free survival (PFS) benefit in patients with newly diagnosed, advanced ovarian cancer in the PAOLA-1/ENGOT-ov25 trial (NCT02477644). We evaluated maintenance olaparib plus bevacizumab in the Japan subset of PAOLA-1.

METHODS

PAOLA-1 was a randomized, double-blind, phase III trial. Patients received maintenance olaparib tablets 300 mg twice daily or placebo twice daily for up to 24 months, plus bevacizumab 15 mg/kg every 3 weeks for up to 15 months in total. This prespecified subgroup analysis evaluated investigator-assessed PFS (primary endpoint).

RESULTS

Of 24 randomized Japanese patients, 15 were assigned to olaparib and 9 to placebo. After a median follow-up for PFS of 27.7 months for olaparib plus bevacizumab and 24.0 months for placebo plus bevacizumab, median PFS was 27.4 versus 19.4 months, respectively (hazard ratio [HR]=0.34; 95% confidence interval [CI]=0.11-1.00). In patients with tumors positive for homologous recombination deficiency, the HR for PFS was 0.57 (95% CI=0.16-2.09). Adverse events in the Japan subset were generally consistent with those of the PAOLA-1 overall population and with the established safety and tolerability profiles of olaparib and bevacizumab.

CONCLUSION

Results in the Japan subset of PAOLA-1 support the overall conclusion of the PAOLA-1 trial demonstrating that the addition of maintenance olaparib to bevacizumab provides a PFS benefit in patients with newly diagnosed, advanced ovarian cancer.

miR-181a overexpression predicts the poor treatment response and early-progression of serous ovarian cancer patients

Ovarian cancer (OC) remains a leading cause of gynecological cancer-related death worldwide, characterized by poor 5-year survival. Molecular markers could serve as crucial tools of personalized prognosis and therapy. Herein, we present miR-181a as novel predictor of OC prognosis, using five independent OC cohorts. In particular, a screening (n = 81) and an institutionally independent validation (n = 100, OVCAD multicenter study) serous OC (SOC) cohorts were analyzed. Bagnoli et al (2016) OC179 (n = 124) to OC133 (n = 100) and TCGA (n = 489) served as external validation cohorts. Patients' survival and disease progression were assessed as clinical endpoint events. Bootstrap analysis was performed for internal validation and decision curve analysis was utilized to evaluate clinical benefit. miR-181a overexpression was unveiled as powerful and independent molecular predictor of patients' poor survival and higher risk for disease progression after debulking surgery and platinum-based chemotherapy. Analysis of the OVCAD institutionally independent cohort, as well as of Bagnoli et al. and TCGA external cohorts further confirmed the unfavorable prognostic nature of miR-181a overexpression in SOC. Strikingly, multivariate prognostic models incorporating miR-181a with established disease markers clearly improved patients' risk-stratification and offered superior clinical benefit in OC prognostication. Conclusively, miR-181a evaluation could augment prognostic accuracy and support precision medicine decisions in OC.

miR-203 is an independent molecular predictor of prognosis and treatment outcome in ovarian cancer: a multi-institutional study

Ovarian cancer (OC) accounts for the most gynecological cancer-related deaths in developed countries. Unfortunately, the lack of both evident early symptoms and effective asymptomatic population screening results in late diagnosis and inevitably poor prognosis. Hence, it is urgent to identify novel molecular markers to support personalized prognosis. In the present study, we have analyzed the clinical significance of miR-203 in OC using two institutionally independent cohorts. miR-203 levels were quantified in a screening (n = 125) and a validation cohort (n = 100, OVCAD multicenter study). Survival analysis was performed using progression and death as clinical endpoint events. Internal validation was conducted by bootstrap analysis, and decision curve analysis was used to evaluate the clinical benefit. Increased miR-203 levels in OC patients were correlated with unfavorable prognosis and higher risk for disease progression, independently of FIGO stage, tumor grade, residual tumor after surgery, chemotherapy response and age. The analysis of the institutionally independent validation cohort (OVCAD study) clearly confirmed the shorter survival outcome of the patients overexpressing miR-203. Additionally, integration of miR-203 levels with the established disease prognostic markers led to a superior stratification of OC patients that can ameliorate prognosis and benefit patient clinical management. In this regard, miR-203 expression constitutes a novel independent molecular marker to improve patients' prognosis in OC.

Decrease in gynecological cancer diagnoses during the COVID-19 pandemic: an Austrian perspective

Background

On March 16, 2020, the federal government of Austria declared a nationwide lockdown due to the COVID-19 pandemic. Since the lockdown, screening examinations and routine checkups have been restricted to prevent the spread of the virus and to increase the hospitals’ bed capacity across the country. This resulted in a severe decline of patient referrals to the hospitals.

Objective

To assess the impact of the COVID-19 pandemic on the rate of newly diagnosed gynecological and breast cancers in Austria.

Methods

Data of 2077 patients from 18 centers in Austria with newly diagnosed gynecological or breast cancer between January and May 2019 and January and May 2020 were collected. Clinical parameters, including symptoms, performance status, co-morbidities, and referral status, were compared between the time before and after the COVID-19 outbreak.

Results

Our results showed a slight increase of newly diagnosed cancers in January and February 2020 as compared with 2019 (+2 and +35%, respectively) and a strong decline in newly diagnosed tumors since the lockdown: −24% in March 2020 versus March 2019, −49% in April 2020 versus April 2019, −49% in May 2020 versus May 2019. Two-thirds of patients diagnosed during the pandemic presented with tumor-specific symptoms compared with less than 50% before the pandemic (p<0.001). Moreover, almost 50% of patients in 2020 had no co-morbidities compared with 35% in 2019 (p<0.001). Patients, who already had a malignant disease, were rarely diagnosed with a new cancer in 2020 as compared with 2019 (11% vs 6%; p<0.001).

Conclusions

The lockdown led to a decreased number of newly diagnosed gynecological and breast cancers. The decreased accessibility of the medical services and postponed diagnosis of potentially curable cancers during the COVID-19 pandemic may be a step backwards in our healthcare system and might impair cancer treatment outcomes. Therefore, new strategies to manage early cancer detection are needed to optimize cancer care in a time of pandemic in the future.

Impact of frailty on the management of patients with gynecological cancer aged 80 years and older

Purpose

To assess the impact of frailty on compliance of standard therapy, complication, rate and survival in patients with gynecological malignancy aged 80 years and older.

Methods

In total, 83 women with gynecological malignancy (vulva, endometrial, ovarian or cervical cancer) who underwent primary treatment between 2007 and 2017 were retrospectively analyzed. Frailty index was calculated and its association with compliance of standard treatment, peri- and postoperative mortality and morbidity, and survival was evaluated.

Results

Frailty was observed in 24.1% of cases. Both frail and non-frail patients were able to receive standard therapy in most cases − 75.0% and 85.7%, respectively (p = 0.27). Frail patients did not show an increased postoperative complication rate. Frail patients had shorter 3 years overall survival rates (28%) when compared to non-frail patients (55%) (p = 0.02). In multivariable analysis high frailty index (Hazard Ratio [HR] 12.15 [1.39–106.05], p = 0.02) and advanced tumor stage (HR 1.33 [1.00–1.76], p = 0.05) were associated with poor overall survival, but not age, histologic grading, performance status, and compliance of standard therapy.

Conclusion

Majority of patients was able to receive standard therapy, as suggested by the tumor board, irrespective of age and frailty. Nonetheless, frailty is a common finding in patients with gynecological malignancy aged 80 years and older. Frail patients show shorter progression-free, and overall survival within this cohort.

Randomized phase III study to evaluate the impact of secondary cytoreductive surgery in recurrent ovarian cancer: Final analysis of AGO DESKTOP III/ENGOT-ov20

6000

Background: The role of secondary cytoreductive surgery in recurrent ovarian cancer (ROC) has been under debate for decades. A recent trial in unselected patients (pts) failed to show an OS benefit. Methods: Pts with ROC and 1st relapse after 6+ months (mos) platinum-free interval (TFIp) were eligible if they presented with a positive AGO-score (PS ECOG 0, ascites ≤500 ml, and complete resection at initial surgery) and were prospectively randomized to second-line chemotherapy alone vs. cytoreductive surgery followed by the same chemotherapy; platinum combination therapy was recommended. OS was primary endpoint in this superiority trial. Results: 407pts were randomized 2010-2014. The TFIp exceeded 12 mos in 75% of pts. 206 pts were allocated to the surgery arm of whom finally 187 (91%) were operated. A complete resection was achieved in 75%; almost 90% in both arms received a platinum-containing second-line chemo. Primary endpoint analysis showed median OS of 53.7 mos with and 46.2 mos without surgery (HR 0.76, 95%CI 0.59-0.97, p=0.03); median PFS was 18.4 and 14 mos (HR: 0.66, 95%CI 0.54-0.82, p<0.001), median time to start of first subsequent therapy (TFST) was 17.9 vs. 13.7 mos in favor of the surgery arm (HR 0.65, 95%CI 0.52-0.81, p<0.001). An analysis according to treatment showed an OS benefit exceeding 12 mos for pts with complete resection (CR) compared to pts without surgery (median 60.7 vs. 46.2 mos); pts with surgery and incomplete resection even did worse (median 28.8 mos). 60 d mortality rates were 0 and 0.5% in the surgery and no-surgery arm. Re-laparotomies were performed in 3.7% of operated pts. Further grade 3/4 adverse events did not differ significantly between arms. Conclusions: This is the first surgical study demonstrating a meaningful survival benefit in OC: Surgery in pts with first relapse and TFIp of 6+ mos and selected by a positive AGO-Score resulted in a significant increase of OS, PFS and TFST with acceptable morbidity and, therefore, should be offered to suitable pts. The benefit was exclusively seen in pts with CR indicating the importance of both the optimal selection of pts (eg. by AGO score) and of centres with expertise and a high chance of achieving a CR. Clinical trial information: NCT01166737.

Molecular Guided Treatments in Gynecologic Oncology: Analysis of a Real-World Precision Cancer Medicine Platform

INTRODUCTION

Advanced gynecologic cancers have a poor prognosis and constitute a major challenge for adequate treatment strategies. By analyzing and targeting molecular alterations, molecular guided treatments may be a viable option for the treatment of advanced gynecologic cancers.

PATIENTS AND METHODS

In this single-center, real-world retrospective analysis of our platform for precision cancer medicine (PCM), we describe the molecular profiling of 72 patients diagnosed with different types of advanced gynecologic malignancies. Tumor samples of the patients were examined by next-generation sequencing panel and immunohistochemistry (IHC).

RESULTS

In total, we identified 209 genetic aberrations in 72 patients. The ten most frequent alterations were TP53 (n = 42, 20%), KRAS (n = 14, 6.6%), PIK3CA (n = 11, 5.2%), PIK3R1 (n = 9, 4.3%), ATR (n = 8, 3.8%), PTEN (n = 8, 3.8%), BRCA1 (n = 6, 2.8%), NF1 (n = 4, 1.9%), NOTCH1 (n = 4, 1.9%), and POLE (n = 4, 1.9%), which account for more than half of all molecular alterations (52.6%). In 21 (29.1%) patients only one mutation could be detected, and 44 (61.1%) patients had more than one mutation. No molecular alterations were detected in seven (9.7%) patients. IHC detected expression of phosphorylated mammalian target of rapamycin and epidermal growth factor receptor in 58 (80.6%) and 53 (73.6%) patients, respectively. In over two thirds (n = 49, 68.1%), a targeted therapy was suggested, based on the identified genetic aberrations. The most frequently recommended specific treatment was the combination of everolimus with exemestane (n = 18, 25 %).

CONCLUSION

Based on our observations, it seems that PCM might be a feasible approach for advanced gynecologic cancers with limited treatment options.

IMPLICATIONS FOR PRACTICE

Nowadays molecular profiling of advanced gynecologic malignancies is feasible in the clinical routine. A molecular portrait should be done for every patient with an advanced therapy-refractory gynecologic malignancy to offer molecular-based treatment concepts.

Effect of Viewing Disney Movies During Chemotherapy on Self-Reported Quality of Life Among Patients With Gynecologic Cancer: A Randomized Clinical Trial

IMPORTANCE

In addition to treatment efficacy, evaluation of adverse effects and quality of life assessments have become increasingly relevant in oncology.

OBJECTIVE

To evaluate the association of watching Disney movies during chemotherapy with emotional and social functioning and fatigue status.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was performed from December 2017 to December 2018 at a cancer referral center in Vienna, Austria. A consecutive sample of women with gynecologic cancers was recruited through July 2018. Inclusion criteria included age older than 18 years, written informed consent, and planned 6 cycles of chemotherapy with either carboplatin and paclitaxel or carboplatin and pegylated liposomal doxorubicin. Exclusion criteria were inadequate knowledge of the German language or receipt of other chemotherapy regimens. Data analysis was performed from February 2019 to April 2019.

INTERVENTION

Participants were either shown Disney movies or not during 6 cycles of chemotherapy. Before and after every cycle, they completed standardized questionnaires from the European Organisation for Research and Treatment of Cancer (EORTC).

MAIN OUTCOMES AND MEASURES

Primary outcomes were change of quality of life, as defined by the EORTC Core-30 (version 3) questionnaire, and fatigue, as defined by the EORTC Quality of Life Questionnaire Fatigue, during 6 cycles of chemotherapy.

RESULTS

Fifty-six women entered the study, and 50 completed it, including 25 women in the Disney group (mean [SD] age, 59 [12] years) and 25 women in the control group (mean [SD] age, 62 [8] years). In the course of 6 cycles of chemotherapy, patients in the Disney group felt less tense and worried less than patients in the control group according to their responses to the questions about emotional functioning (mean [SD] score, 86.9 [14.3] vs 66.3 [27.2]; maximum test P = .02). Furthermore, watching Disney movies was associated with less encroachment on patients' family life and social activities, as evaluated by the social functioning questions (mean [SD] score, 86.1 [23.0] vs 63.6 [33.6]; maximum test P = .01). Moreover, this intervention led to fewer fatigue symptoms (mean [SD] score, 85.5 [13.6] vs 66.4 [22.5]; maximum test P = .01). Perceived global health status was not associated with watching Disney movies (mean [SD] score, 75.9 [17.6] vs 61.0 [25.1]; maximum test P = .16).

CONCLUSIONS AND RELEVANCE

These findings suggest that watching Disney movies during chemotherapy may be associated with improvements in emotional functioning, social functioning, and fatigue status in patients with gynecologic cancers.

Bevacizumab and platinum-based combinations for recurrent ovarian cancer: a randomised, open-label, phase 3 trial

BACKGROUND

State-of-the art therapy for recurrent ovarian cancer suitable for platinum-based re-treatment includes bevacizumab-containing combinations (eg, bevacizumab combined with carboplatin-paclitaxel or carboplatin-gemcitabine) or the most active non-bevacizumab regimen: carboplatin-pegylated liposomal doxorubicin. The aim of this head-to-head trial was to compare a standard bevacizumab-containing regimen versus carboplatin-pegylated liposomal doxorubicin combined with bevacizumab.

METHODS

This multicentre, open-label, randomised, phase 3 trial, was done in 159 academic centres in Germany, France, Australia, Austria, and the UK. Eligible patients (aged ≥18 years) had histologically confirmed epithelial ovarian, primary peritoneal, or fallopian tube carcinoma with first disease recurrence more than 6 months after first-line platinum-based chemotherapy, and an Eastern Cooperative Oncology Group performance status of 0-2. Patients were stratified by platinum-free interval, residual tumour, previous antiangiogenic therapy, and study group language, and were centrally randomly assigned 1:1 using randomly permuted blocks of size two, four, or six to receive six intravenous cycles of bevacizumab (15 mg/kg, day 1) plus carboplatin (area under the concentration curve [AUC] 4, day 1) plus gemcitabine (1000 mg/m², days 1 and 8) every 3 weeks or six cycles of bevacizumab (10 mg/kg, days 1 and 15) plus carboplatin (AUC 5, day 1) plus pegylated liposomal doxorubicin (30 mg/m², day 1) every 4 weeks, both followed by maintenance bevacizumab (15 mg/kg every 3 weeks in both groups) until disease progression or unacceptable toxicity. There was no masking in this open-label trial. The primary endpoint was investigator-assessed progression-free survival according to Response Evaluation Criteria in Solid Tumors version 1.1. Efficacy data were analysed in the intention-to-treat population. Safety was analysed in all patients who received at least one dose of study drug. This completed study is registered with ClinicalTrials.gov, NCT01837251.

FINDINGS

Between Aug 1, 2013, and July 31, 2015, 682 eligible patients were enrolled, of whom 345 were randomly assigned to receive carboplatin-pegylated liposomal doxorubicin-bevacizumab (experimental group) and 337 were randomly assigned to receive carboplatin-gemcitabine-bevacizumab (standard group). Median follow-up for progression-free survival at data cutoff (July 10, 2018) was 12·4 months (IQR 8·3-21·7) in the experimental group and 11·3 months (8·0-18·4) in the standard group. Median progression-free survival was 13·3 months (95% CI 11·7-14·2) in the experimental group versus 11·6 months (11·0-12·7) in the standard group (hazard ratio 0·81, 95% CI 0·68-0·96; p=0·012). The most common grade 3 or 4 adverse events were hypertension (88 [27%] of 332 patients in the experimental group vs 67 [20%] of 329 patients in the standard group) and neutropenia (40 [12%] vs 73 [22%]). Serious adverse events occurred in 33 (10%) of 332 patients in the experimental group and 28 (9%) of 329 in the standard group. Treatment-related deaths occurred in one patient in the experimental group (<1%; large intestine perforation) and two patients in the standard group (1%; one case each of osmotic demyelination syndrome and intracranial haemorrhage).

INTERPRETATION

Carboplatin-pegylated liposomal doxorubicin-bevacizumab is a new standard treatment option for platinum-eligible recurrent ovarian cancer.

Olaparib plus Bevacizumab as First-Line Maintenance in Ovarian Cancer

BACKGROUND

Olaparib has shown significant clinical benefit as maintenance therapy in women with newly diagnosed advanced ovarian cancer with a BRCA mutation. The effect of combining maintenance olaparib and bevacizumab in patients regardless of BRCA mutation status is unknown.

METHODS

We conducted a randomized, double-blind, international phase 3 trial. Eligible patients had newly diagnosed, advanced, high-grade ovarian cancer and were having a response after first-line platinum-taxane chemotherapy plus bevacizumab. Patients were eligible regardless of surgical outcome or BRCA mutation status. Patients were randomly assigned in a 2:1 ratio to receive olaparib tablets (300 mg twice daily) or placebo for up to 24 months; all the patients received bevacizumab at a dose of 15 mg per kilogram of body weight every 3 weeks for up to 15 months in total. The primary end point was the time from randomization until investigator-assessed disease progression or death.

RESULTS

Of the 806 patients who underwent randomization, 537 were assigned to receive olaparib and 269 to receive placebo. After a median follow-up of 22.9 months, the median progression-free survival was 22.1 months with olaparib plus bevacizumab and 16.6 months with placebo plus bevacizumab (hazard ratio for disease progression or death, 0.59; 95% confidence interval [CI], 0.49 to 0.72; P<0.001). The hazard ratio (olaparib group vs. placebo group) for disease progression or death was 0.33 (95% CI, 0.25 to 0.45) in patients with tumors positive for homologous-recombination deficiency (HRD), including tumors that had BRCA mutations (median progression-free survival, 37.2 vs. 17.7 months), and 0.43 (95% CI, 0.28 to 0.66) in patients with HRD-positive tumors that did not have BRCA mutations (median progression-free survival, 28.1 vs. 16.6 months). Adverse events were consistent with the established safety profiles of olaparib and bevacizumab.

CONCLUSIONS

In patients with advanced ovarian cancer receiving first-line standard therapy including bevacizumab, the addition of maintenance olaparib provided a significant progression-free survival benefit, which was substantial in patients with HRD-positive tumors, including those without a BRCA mutation.

TRUST: Trial of Radical Upfront Surgical Therapy in advanced ovarian cancer (ENGOT ov33/AGO-OVAR OP7)

BACKGROUND

Primary cytoreductive surgery followed by chemotherapy has been considered standard management for patients with advanced ovarian cancer over decades. An alternative approach of interval debulking surgery following neoadjuvant chemotherapy was subsequently reported by two randomized phase III trials (EORTC-GCG, CHORUS), which were criticized owing to important limitations, especially regarding the rate of complete resection.

PRIMARY OBJECTIVE

To clarify the optimal timing of surgical therapy in advanced ovarian cancer.

STUDY HYPOTHESIS

Primary cytoreductive surgery is superior to interval cytoreductive surgery following neoadjuvant chemotherapy for overall survival in patients with advanced ovarian cancer.

TRIAL DESIGN

TRUST is an international open, randomized, controlled multi-center trial investigating overall survival after primary cytoreductive surgery versus neoadjuvant chemotherapy and subsequent interval cytoreductive surgery in patients with FIGO stage IIIB-IVB ovarian, tubal, and peritoneal carcinoma. To guarantee adequate surgical quality, participating centers need to fulfill specific quality assurance criteria (eg, ≥50% complete resection rate in upfront surgery for FIGO IIIB-IVB patients, ≥36 debulking-surgeries/year) and agree to independent audits by TRUST quality committee delegates. Patients in the primary cytoreductive surgery arm undergo surgery followed by 6 cycles of platinum-based chemotherapy, whereas patients in the interval cytoreductive surgery arm undergo 3 cycles of neoadjuvant chemotherapy after histologic confirmation of the disease, followed by interval cytoreductive surgery and subsequently, 3 cycles of platinum-based chemotherapy. The intention of surgery for both groups is complete tumor resection according to guideline recommendations.

MAJOR INCLUSION/EXCLUSION CRITERIA

Major inclusion criteria are suspected or histologically confirmed, newly diagnosed invasive epithelial ovarian cancer, fallopian tube carcinoma, or primary peritoneal carcinoma FIGO stage IIIB-IVB (IV only if resectable metastasis). Major exclusion criteria are non-epithelial ovarian malignancies and borderline tumors; prior chemotherapy for ovarian cancer; or abdominal/pelvic radiotherapy.

PRIMARY ENDPOINT

Overall survival.

SAMPLE SIZE

772 patients.

ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS

Accrual completion approximately mid-2019, results are expected after 5 years' follow-up in 2024.

TRIAL REGISTRATION

Pre-operative hypoalbuminemia is associated with complication rate and overall survival in patients with vulvar cancer undergoing surgery

Objective

Hypoalbuminemia, a known marker for malnutrition, has been associated with an increased risk for perioperative morbidity and poor prognosis in patients with solid tumors. The aim of this study was to investigate the prognostic and predictive value of pre-treatment serum albumin levels for survival and postoperative complications in patients with vulvar cancer undergoing surgery.

Methods

Within in this retrospective study, we assessed data of 103 consecutive patients with vulvar cancer undergoing primary surgery into this study. Pre-treatment serum albumin levels were correlated with clinico-pathological parameters and complications. We performed univariate log-rank test and multivariable Cox regression models to evaluate the association between pre-treatment serum albumin and survival.

Results

We found hypoalbuminemia (< 35 mg/dl) in 9 of 103 (8.7%) patients. No difference in tumor characteristics was observed between patients with hypoalbuminemia and normal serum albumin levels. Difference in postoperative complications (55.6% and 37.8% of patients with hypoalbuminemia and normal serum albumin levels, respectively) was not statistically significant (p = 0.345). Shorter overall survival (OS) was observed in patients with hypoalbuminemia (5-year OS rate 17.1%) when compared to patients with normal serum albumin levels (5-year OS rate 58.6%, p = 0.004). In multivariable analysis, age (p = 0.017), FIGO stage (p = 0.011) and serum albumin levels (p = 0.013) were independently associated with OS.

Conclusion

Pre-treatment hypoalbuminemia is an independent prognostic biomarker for OS in patients with vulvar cancer. We did not find an association between pre-treatment hypoalbuminemia and a higher risk for postoperative complications.

Prognostic value of serum creatine level in patients with vulvar cancer

Vulvar cancer is a rare malignancy with poor prognosis that generally occurs in elderly patients. The individual prognosis is difficult to assess. Serum creatinine levels are frequently elevated in elderly patients. Recent evidence have shown shown that - besides indicating kidney impairment - serum creatinine levels may be used to predict the survival in cancer patients. Several studies observed an association between elevated serum creatinine levels and poor prognosis in patients with solid tumors. In this retrospective cohort study, serum creatinine levels were evaluated in 170 patients with invasive vulvar cancer. Serum creatinine levels were correlated to established clinicopathologic factors. Univariate and multivariate survival analysis were performed. Elevated serum creatinine levels (>1.2 mg/dl) were significantly associated with both poor disease specific and overall survival. Three year overall survival rates were 74.8% and 32.5% for patients with serum creatinine levels of ≤ and >1.2 mg/dl, respectively. In a multivariate survival model, serum creatinine levels were significantly associated with overall survival independent of tumor stage and patients’ age. In conclusion, pretherapeutic serum creatinine levels may be useful as an independent prognostic parameter in patients with vulvar cancer.

Low anterior resection syndrome (LARS) in patients with epithelial ovarian cancer after primary debulking surgery

OBJECTIVE

To evaluate the prevalence of low anterior resection syndrome (LARS) in patients with debulking surgery for primary advanced epithelial ovarian cancer and to identify potential risk factors for development of LARS.

METHODS

We reviewed data on 552 consecutive patients with primary epithelial ovarian cancer (EOC), who underwent upfront or interval cytoreductive surgery including low anterior resection at two different academic institutions (Kliniken-Essen-Mitte, Germany, and Medical University of Vienna, Austria). Intestinal dysfunction was assessed by the validated LARS-questionnaire via telephone call. We performed descriptive statistics and a binary logistic regression model to evaluate risk factors for LARS.

RESULTS

In total, 341 patients were eligible and 206 (60.4%) were successfully contacted and provided complete information. Major LARS was observed in 78 (37.9%) patients, minor LARS in 44 (21.4%) patients, and no LARS in 84 (40.8%) patients. The prevalence rate of major LARS was not influenced by time interval between surgery and LARS assessment, type of cytoreductive surgery, and recurrent disease at the time of assessment. In multivariate analyses, number of anastomosis was independently associated with an increased risk for presence of major LARS (OR 3.76 [1.95-7.24]). In the present cohort, 25.2% patients had more than one bowel anastomosis.

CONCLUSIONS

LARS in general and major LARS in particular seem to be a frequent long-term complication after debulking surgery including low anterior resection in primary advanced EOC patients. Particularly EOC patients with more than one bowel anastomosis during surgery seem to be at an increased risk for major LARS.

Gamma-glutamyltransferase as a preoperative differential diagnostic marker in patients with adnexal mass

OBJECTIVE

Gamma-glutamyltransferase (GGT) is involved in tumor development, progression and chemotherapy resistance. The present study evaluated GGT serum levels as a preoperative predictive marker for ovarian cancer in patients with adnexal mass.

STUDY DESIGN

Preoperative GGT serum levels of 2235 patients with adnexal mass and subsequent surgery were ascertained (patients with benign ovarian tumors: n = 1811; borderline tumor of the ovary [BTO]: n = 85; epithelial ovarian cancer [EOC]: n = 339). Standardized expert transvaginal ultrasound was documented.

RESULTS

Median (interquartile range) GGT serum levels in patients with benign ovarian tumors, BTO, and EOC were 15.0 U/l (11.0-23.0), 17.0 U/l (10.0-23.5), and 20.0 U/l (13.0-34.0), respectively (p = 0.002). Elevated GGT serum levels were associated with the presence of BTO/EOC in univariate analysis (p < 0.0001, hazard ratio 1.8, confidence interval 1.5-2.3). GGT did not outperform established tools for preoperative prediction of BTO/EOC in patients with adnexal mass, such as CA-125 measurement or transvaginal ultrasound.

CONCLUSION

Elevated GGT serum levels were not associated with the presence of BTO/EOC in women with suspicious adnexal mass in multivariate analysis. GGT serum levels did not outperform established risk factors and therefore might add only limited additional value to CA-125 serum levels in the differential diagnosis between benign and malignant adnexal masses.

Heavy black tea consumption and elevated CA 19-9 and CA 125 levels. A case report on a patient with ovarian endometriotic cysts

In this case report, we present a case of false positive CA 19-9 and CA 125 levels in a patient with suspected endometriotic cysts. The patient is a 34-year-old nulliparous woman with heavy black tea consumption and elevated CA 19-9 and CA 125 levels. After discontinuation of black tea intake and careful exploration of other possible factors, CA 19-9 and CA 125 levels dropped markedly. As a conclusion, heavy black tea consumption can lead to false positive results of elevated CA 19-9 and CA 125 levels.

Patient-derived cell line models revealed therapeutic targets and molecular mechanisms underlying disease progression of high grade serous ovarian cancer

High grade serous ovarian cancer (HGSOC) is the most frequent type of ovarian cancer. Most patients have primary response to platinum-based chemotherapy but frequently relapse, which leads to patient death. A lack of well documented and characterized patient-derived HGSOC cell lines is so far a major barrier to define tumor specific therapeutic targets and to study the molecular mechanisms underlying disease progression. We established 34 patient-derived HGSOC cell lines and characterized them at cellular and molecular level. Particularly, we demonstrated that a cancer-testis antigen PRAME and Estrogen Receptor could serve as therapeutic targets. Notably, data from the cell lines did not demonstrate acquired resistance due to tumor recurrence that matched with clinical observations. Finally, we presented that all HGSOC had no or very low CDKN1A (p21) expression due to loss of wild-type TP53, suggesting that loss of cell cycle control is the determinant for tumorigenesis and progression. In conclusion, patient-derived cell lines reveal that PRAME is a potential tumor specific therapeutic target in HGSOC and counteracting the down-regulation of p21 caused by loss of wild-type TP53 might be the key to impede disease progression.
