RESUMO
BACKGROUND: This study aimed to describe the treatment strategies and outcomes for women with newly diagnosed advanced high-grade serous or endometrioid ovarian cancer (OC). METHODS: This observational study collected real-world medical record data from eight Western countries on the diagnostic workup, clinical outcomes, and treatment of adult women with newly diagnosed advanced (Stage III-IV) high-grade serous or endometrioid OC. Patients were selected backward in time from April 1, 2018 (the index date), with a target of 120 patients set per country, followed for ≥20 months. RESULTS: Of the 1119 women included, 66.9% had Stage III disease, 11.7% had a deleterious BRCA mutation, and 26.6% received bevacizumab; 40.8% and 39.3% underwent primary debulking surgery (PDS) and interval debulking surgery (IDS), respectively. Of the patients who underwent PDS, 55.5% had no visible residual disease (VRD); 63.9% of the IDS patients had no VRD. According to physician-assessed responses (at the first assessment after diagnosis and treatment), 53.2% of the total population had a complete response and 25.7% had a partial response to first-line chemotherapy after surgery. After ≥20 months of follow-up, 32.9% of the patients were disease-free, 46.4% had progressive disease, and 20.6% had died. Bevacizumab use had a significant positive effect on overall survival (hazard ratio [HR], 0.62; 95% CI, 0.42-0.91; p = .01). A deleterious BRCA status had a significant positive effect on progression-free survival (HR, 0.60; 95% CI, 0.41-0.84; p < .01). CONCLUSIONS: Women with advanced high-grade serous or endometrioid OC have a poor prognosis. Bevacizumab use and a deleterious BRCA status were found to improve survival in this real-world population. LAY SUMMARY: Patients with advanced (Stage III or IV) ovarian cancer (OC) have a poor prognosis. The standard treatment options of surgery and chemotherapy extend life beyond diagnosis for 5 years or more in only approximately 45% of patients. This study was aimed at describing the standard of care in eight Western countries and estimating how many patients who are diagnosed with high-grade serous or endometrioid OC could potentially be eligible for first-line poly(adenosine diphosphate ribose) polymerase inhibitor (PARPi) maintenance therapy. The results highlight the poor prognosis for these patients and suggest that a significant proportion (79%) would potentially be eligible for first-line PARPi maintenance treatment.

OBJECTIVE: To examine clinical trends in Denmark for younger and older epithelial ovarian cancer (EOC) patients, focusing on incidence, treatment, and survival changes. METHODS: We included a nationwide cohort diagnosed with EOC from 2005 to 2018. We described age-standardized incidence, surgical patterns, residual disease trends, and cancer-specific survival stratified by age (<70 and ≥ 70 years), stage, and period (2005-09, 2010-13, 2014-18). RESULTS: We included 7522 patients. The incidence decreased from 16.3 (2005) to 11.4 (2018) per 100,000 woman-years, driven by the younger cohort. While the proportion of patients with stage IIIC-IV disease undergoing primary debulking surgery (PDS) decreased, the proportion of patients having interval debulking surgery (IDS) and no debulking surgery increased significantly. In 2014-18, 36% and 24% had PDS for younger and older patients, respectively, compared to 72% and 62% in 2005-09. In both age cohorts, the proportion of patients debulked to no residual disease increased significantly among patients with stage IIIC-IV and in the total cohort. Two-year cancer-specific survival increased from 75% (2005-09) to 84% (2014-18) for younger patients and from 53% to 66% for older patients. After adjusting for potential confounders, age ≥ 70 was associated with a 1.4-fold increased risk of cancer-specific death (95% confidence interval: 1.2,1.5). CONCLUSIONS: The proportion of patients with advanced EOC not undergoing PDS or IDS increased significantly. During the same period, patients debulked to no residual disease, and cancer-specific survival increased. However, a survival gap in favor of the younger patients remains after adjusting for potential confounders.

INTRODUCTION: Radical surgery combined with chemotherapy is the only potential curative treatment of patients with advanced epithelial ovarian cancer (EOC). However, 43% of older Danish patients with EOC are not referred to surgery due to frailty, age, or fear of complications. Comprehensive geriatric assessment (CGA) has demonstrated ability to reduce frailty in older patients, but there is a knowledge gap regarding its effect before or during treatment in older adults with EOC. This protocol presents a randomized controlled trial (RCT), which evaluates the effect of CGA-based interventions including individualized physical exercise therapy in older adults with EOC during neoadjuvant chemotherapy (NACT). MATERIALS AND METHODS: This RCT will include patients aged ≥70 years with primary EOC referred to NACT. Patients will be randomized 1:1 to intervention or standard of care, along with neoadjuvant antineoplastic treatment. Stratification for performance status and center of inclusion will be performed. In the intervention arm, a geriatrician will perform CGA and corresponding geriatric interventions and patients will undergo an individualized home-based exercise program managed by a physiotherapist. All patients will be evaluated with Geriatric-8, modified Geriatric-8, clinical frailty scale, and physical tests at randomization. Predictive values (positive/negative) will be evaluated for CGA detected impairments. The primary endpoint is the proportion of patients referred to interval debulking surgery (IDS). Secondary endpoints include the proportion who complete oncological treatment, improvements in physical tests, quality of life measured by European Organization for Research and Treatment of Cancer-Quality of Life questionnaires at inclusion, after three cycles of chemotherapy, and at end of chemotherapy treatment. Furthermore, the association between results of geriatric screening tests, CGA, and physical tests with complication rate and progression free survival will be examined. The primary outcome will be analyzed with logistic regression in the intention-to-treat population. Power calculations reveal the need to enroll 216 patients. DISCUSSION: The present study examines whether CGA-based interventions including individualized physical exercise can increase the referral rate for potential curative IDS in older patients with EOC. If successful, this will result in more patients undergoing surgery and completing chemotherapy, preventing complications, and ultimately improving quality of life and survival. The study setup may establish the basis for direct clinical implementation if proven effective.

INTRODUCTION: To explore differences in surgical complexity, chemotherapy administration, and treatment delays between younger and older Danish patients with epithelial ovarian cancer (EOC). MATERIALS AND METHODS: We included a nationwide cohort diagnosed with EOC from 2013 to 2018. We described surgical complexity and outcomes, the extent of chemotherapy and treatment delays stratified by age (<70 and ≥ 70 years), and surgical modality (primary, interval, or no debulking surgery). RESULTS: In total, we included 2946 patients. For patients with advanced-stage disease, 52% of the older patients versus 25% of the younger patients did not undergo primary debulking surgery (PDS) or interval debulking surgery (IDS). For patients undergoing PDS or IDS, older patients underwent less extensive surgery and more often had residual disease after surgery >0 cm compared to younger patients. Furthermore, older patients were less often treated with chemotherapy. Older patients had PDS later than younger. We did not find any differences between age groups concerning treatment delays. Two-year cancer-specific survival differed significantly between age groups regardless of curatively intended treatment. DISCUSSION: This study demonstrates that older patients are treated less actively concerning surgical and oncological treatment than younger patients, leading to worse cancer-specific survival. Older patients do not experience more treatment delays than younger ones.

OBJECTIVE: Days alive and out of hospital (DAOH) is a validated outcome measure in perioperative trials integrating information on primary hospitalization, readmissions, and mortality. It is negatively associated with advanced age. However, DAOH has not been described for surgical treatment of epithelial ovarian cancer (EOC), primarily diagnosed in older patients. METHODS: We conducted a Danish nationwide cohort study including patients undergoing debulking surgery for EOC from 2013 to 2018. DAOH was explored for 30 (DAOH30), 90 (DAOH90), and 180 (DAOH180) postoperative days in younger (<70 years) and older (≥70 years) patients with advanced-stage disease stratified by surgical modality (primary (PDS) or interval debulking surgery (IDS)). We examined the associations between patient- and surgical outcomes and low or high DAOH30. RESULTS: Overall, 1168 patients had stage IIIC-IV disease and underwent debulking surgery. DAOH30 was 22 days [interquartile range (IQR): 18, 25] and 23 days [IQR: 18, 25] for younger and older patients treated with PDS, respectively. For IDS, DAOH30 was 25 days [IQR: 22, 26] for younger and 25 days[IQR: 21, 26] for older patients. We found no significant differences between age cohorts regarding DAOH30, DAOH90, and DAOH180. Low DAOH30 was associated with poor performance status, PDS, extensive surgery, and long duration of surgery in adjusted analysis. CONCLUSIONS: DAOH did not differ significantly between age cohorts. Surgical rather than patient-related factors were associated with low DAOH30. Our results likely reflect a high selection of fit older patients for surgery, reducing the patient-related differences between younger and older patients receiving surgical treatment.

BACKGROUND/AIM: The aim of the study was to compare platinum resistance and treatment-free interval (TFI) following treatment with neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) or primary debulking surgery (PDS) in women with advanced epithelial ovarian cancer (EOC). PATIENTS AND METHODS: The study included patients diagnosed with primary EOC, stage IIIC or IV, between 2005 and 2013. Patients were grouped according to first-line treatment (PDS vs. NACT-IDS). Date of second-line treatment initiation was used to evaluate platinum sensitivity. RESULTS: The study population included 521 patients, of which 371 (71%) and 150 (29%) underwent PDS and NACT-IDS, respectively. We found no difference in platinum resistance between groups. Platinum-sensitive patients treated with NACT-IDS had a shorter median TFI (372 vs. 497 days, p=0.042). Similarly, patients with no residual tumor after IDS had a shorter median TFI (280 vs. 302 days, p=0.005). CONCLUSION: NACT-IDS may shorten the TFI after first-line platinum-based chemotherapy.

OBJECTIVE: Ovarian cancer is the leading cause of death among gynecologic malignancies. This is partly due to a non-durable response to chemotherapy. Prediction of resistance to chemotherapy could be a key role in more personalized treatment. In the current study we aimed to examine if microRNA based predictors could predict resistance to chemotherapy in ovarian cancer, and to investigate if the predictors could be prognostic factors for progression free and overall survival. METHODS: Predictors of chemotherapy-resistance were developed based on correlation between miRNA expression and differences in measured growth inhibition in a variety of human cancer cell lines in the presence of Carboplatin, Paclitaxel and Docetaxel. These predictors were then, retrospectively, blindly validated in a cohort of 170 epithelial ovarian cancer patients treated with Carboplatin and Paclitaxel or Docetaxel as first line treatment. RESULTS: In a multivariate cox proportional analysis the predictors of chemotherapy-resistance were not able to predict time to progression after end of chemotherapy (hazard ratio: 0.64, 95% CI: 0.36-1.12, P = 0.117). However, in a multivariate logistic analysis, where time to progression was considered as either more or less than 6 months, the predictors match clinical observed chemotherapy-resistance (odds ratio: 0.19, 95% CI: 0.05-0.73, P = 0.015). Neither univariate nor multivariate, time-dependent, cox analysis for progression free survival (PFS) or overall survival (OS) in all 170 patients showed to match predicted resistance to chemotherapy (PFS: hazard ratio: 0.69, 95% CI: 0.40-1.19, P = 0.183, OS: hazard ratio: 0.76, 95% CI: 0.42-1.40, P = 0.386). CONCLUSION: In the current study, microRNA based predictors of chemotherapy-resistance did not demonstrate any convincing correlation to clinical observed chemotherapy-resistance, progression free survival, or overall survival, in patients with epithelial ovarian cancer. However the predictors did reflect relapse more or less than 6 months.
