Project description:IntroductionIt is debated whether women with FIGO (International Federation of Gynecology and Obstetrics) Stage IV epithelial ovarian cancer should be offered primary debulking surgery (PDS) or interval debulking surgery (IDS). Furthermore, the impact of complete resection of intra-abdominal disease (R0) despite their extra-abdominal metastases is questioned. The objective of this study was to investigate the impact of intra-abdominal residual tumor, Stage IVA vs IVB, the localization and number of metastases defining Stage IV disease on overall survival (OS) comparing PDS and IDS in FIGO Stage IV epithelial ovarian cancer.Material and methodsWe included 2091 women registered with Stage IIIC-IV ovarian cancer in the Danish Gynecological Cancer Database during 2009-2016. The impact of residual tumor was evaluated using univariate and multivariate analyses.ResultsIn total, 681 patients had stage IV disease, of whom 26% underwent PDS, 38% IDS, and 36% chemotherapy only. Overall survival for PDS and IDS were similar. Patients achieving R0 at PDS showed a tendency towards a higher OS than patients achieving R0 at IDS, though the difference was non-significant. In women with Stage IVA and IVB disease there was a survival benefit in achieving R0 both when treated with PDS and IDS. Women with Stage IVB disease treated with chemotherapy only had a significantly lower OS than patients achieving R0 at both PDS and IDS. Malignant pleural effusion and having five metastatic sites compared with having one was associated with a poorer OS.ConclusionsOur study shows similar OS in patients with Stage IV disease treated with IDS compared with PDS. Complete intra-abdominal tumor resection improves the prognosis in both PDS and IDS in Stage IV ovarian cancer. Malignant pleural effusion seems to be a negative prognostic factor and should have more focus in future studies.

Project description:BackgroundSarcopenia is commonly observed in patients with advanced-stage epithelial ovarian cancer (EOC). However, the effect of body composition changes-during primary debulking surgery (PDS) and adjuvant platinum-based chemotherapy-on outcomes of patients with advanced-stage EOC is unknown. This study aimed to evaluate the association between body composition changes and outcomes of patients with stage III EOC treated with PDS and adjuvant platinum-based chemotherapy.MethodsPre-treatment and post-treatment computed tomography (CT) images of 139 patients with stage III EOC were analysed. All CT images were contrast-enhanced scans and were acquired according to a standardized protocol. The skeletal muscle index (SMI), skeletal muscle radiodensity (SMD), and total adipose tissue index were measured using CT images obtained at the L3 vertebral level. Predictors of overall survival were identified using Cox regression models.ResultsThe median follow-up was 37.9 months. The median duration between pre-treatment and post-treatment CT was 182 days (interquartile range: 161-225 days). Patients experienced an average SMI loss of 1.8%/180 days (95% confidence interval: -3.1 to -0.4; P = 0.01) and SMD loss of 1.7%/180 days (95% confidence interval: -3.3 to -0.03; P = 0.046). SMI and SMD changes were weakly correlated with body mass index changes (Spearman ρ for SMI, 0.15, P = 0.07; ρ for SMD, 0.02, P = 0.82). The modified Glasgow prognostic score was associated with SMI loss (odds ratio: 2.42, 95% confidence interval: 1.03-5.69; P = 0.04). The median time to disease recurrence was significantly shorter in patients with SMI loss ≥5% after treatment than in those with SMI loss <5% or gain (5.4 vs. 11.2 months, P = 0.01). Pre-treatment SMI (1 cm2 /m2 decrease; hazard ratio: 1.08, 95% confidence interval: 1.03-1.11; P = 0.002) and SMI change (1%/180 days decrease; hazard ratio: 1.04, 95% confidence interval: 1.01-1.08; P = 0.002) were independently associated with poorer overall survival. SMD, body mass index, and total adipose tissue index at baseline and changes were not associated with overall survival.ConclusionsSkeletal muscle index decreased significantly during treatment and was independently associated with poor overall survival in patients with stage III EOC treated with PDS and adjuvant platinum-based chemotherapy. The modified Glasgow prognostic score might be a predictor of SMI loss during treatment.

Project description:The object of this study is to evaluate the clinical safety and efficacy of total parietal peritonectomy (TPP) in primary debulking surgery (PDS) for advanced ovarian cancer. This retrospective single-center study analyzed 16 patients with FIGO stages IIIC-IVB epithelial ovarian cancer who underwent TPP in PDS and achieved macroscopically complete resection between April 2015 and June 2016. The median age of 16 patients was 52.5 years old. 12 were in stage IIIC and 4 were in stage IV. Regarding intraoperative complications, unintended diaphragm perforation was observed in two patients. Regarding postoperative complications (Clavien-Dindo classification grade 3-5) before the adjuvant chemotherapy, lymph cysts occured in 3 patients, intra-abdominal abscess in 3, ileus in 2, pancreatic fistula in 1 and temporary kidney failure in 1. Regarding postoperative complications (grade 3-5) after the initiation of adjuvant chemotherapy, diaphragmatic hernia occured in 1 patient, ileus in 2 and intra-abdominal abscess in 2. Except 1 patient who relapsed approximately one month from surgery and died, the other 15 patients overcamed complications and recovered without problems in daily life. This analysis was conducted 3 years after all patients underwent PDS, with the 3-year progression-free and overall survival of 62.5% (95% confidence interval [CI], 34.9-81.1) and 87.5% (95 %CI, 58.6-96.7), respectively. Based on the above results, TPP in PDS may improve the prognosis compared to previous reports such as LION trial. On the other hand, complications may increase. Therefore, further studies are necessary on its safety and efficacy.

Project description:ObjectiveThe aim of this study was to evaluate the use of neoadjuvant chemotherapy (NACT) and primary debulking surgery (PDS) before and after results from a randomized trial were published and showed non-inferiority between NACT and PDS in the management of advanced-stage ovarian carcinoma.MethodsWe evaluated consecutive patients with advanced-stage ovarian cancer treated at our institution from 1/1/08-5/1/13, which encompassed 32 months before and 32 months after the randomized trial results were published. We included all newly diagnosed patients with high-grade histology and stage III/IV disease. Associations between the use of NACT and clinical variables over time were evaluated.ResultsOur study included 586 patients. Median age was 62 years (range, 30-90); 406 patients (69%) had stage III disease, and 570 (97%) had disease of serous histology. Twenty-six percent (154/586) were treated with NACT and 74% (432/586) with PDS. NACT use increased significantly from 22% (56/256) before 2010 (at which point the results of the randomized trial were published) to 30% (98/330) after 2010 (p=0.037). Although patients who underwent PDS were more likely to experience grade 3/4 surgical complications than those who underwent NACT, those selected for PDS had a median OS of 71.7 months (CI, 59.8-not reached) compared with 42.9 months (CI 37.1-56.3) for those selected for NACT.ConclusionsIn this single-institution analysis, the best survival outcomes were observed in patients who were deemed eligible for PDS followed by platinum-based chemotherapy. Selection criteria for NACT require further definition and should take institutional surgical strategy into account.

Project description:ObjectiveOptimal debulking with no macroscopic residual disease strongly predicts ovarian cancer survival. The ability to predict likelihood of optimal debulking, which may be partially dependent on tumor biology, could inform clinical decision-making regarding use of neoadjuvant chemotherapy. Thus, we developed a prediction model including epidemiological factors and tumor markers of residual disease after primary debulking surgery.MethodsUnivariate analyses examined associations of 11 pre-diagnosis epidemiologic factors (n=593) and 24 tumor markers (n=204) with debulking status among incident, high-stage, epithelial ovarian cancer cases from the Nurses' Health Studies and New England Case Control study. We used Bayesian model averaging (BMA) to develop prediction models of optimal debulking with 5x5-fold cross-validation and calculated the area under the curve (AUC).ResultsCurrent aspirin use was associated with lower odds of optimal debulking compared to never use (OR=0.52, 95%CI=0.31-0.86) and two tissue markers, ADRB2 (OR=2.21, 95%CI=1.23-4.41) and FAP (OR=1.91, 95%CI=1.24-3.05) were associated with increased odds of optimal debulking. The BMA selected aspirin, parity, and menopausal status as the epidemiologic/clinical predictors with the posterior effect probability ≥20%. While the prediction model with epidemiologic/clinical predictors had low performance (average AUC=0.49), the model adding tissue biomarkers showed improved, but weak, performance (average AUC=0.62).ConclusionsAddition of ovarian tumor tissue markers to our multivariable prediction models based on epidemiologic/clinical data slightly improved the model performance, suggesting debulking status may be in part driven by tumor characteristics. Larger studies are warranted to identify those at high risk of poor surgical outcomes informing personalized treatment.

Project description:OBJECTIVE:To assess whether neoadjuvant chemotherapy (NACT) is superior to primary debulking surgery (PDS) with regard to optimal cytoreduction, peri-operative morbidity, mortality, and quality of life (QOL) in advanced epithelial ovarian cancer (EOC). METHODS:We searched the PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, Registers of Clinical Trials for randomized controlled trials (RCTs) comparing NACT to PDS in women with Federation of International Gynaecologists and Obstetricians stage Ⅲ-Ⅳ EOC. RevMan 5.3 software was utilized for statistical analysis. RESULTS:Four RCTs involving 1,607 women with advanced EOC were included. Compared with PDS, NACT provided a higher rate of complete cytoreduction (risk ratio [RR], 1.95; 95% confidence interval [CI], 1.33 to 2.87), optimal cytoreduction (RR: 1.61 [95%CI: 1.05 to 2.47]), but there was no significant difference in residual disease 0-1 cm (p = 0.49). NACT was associated with lower peri-operative morbidity with respect to infection (RR: 0.30 [95% CI: 0.16 to 0.56]), gastrointestinal fistula (RR: 0.24 [95% CI: 0.06 to 0.95]), any grade 3 or 4 adverse event (RR: 0.29 [95% CI: 0.11 to 0.78]), and less post-surgical death within 28 days (RR: 0.14 [95% CI: 0.04 to 0.49]). NACT provided better QOL in terms of fatigue (weight mean difference [WMD], -3.28; [95% CI: -3.99 to -2.57]), role functioning (WMD: 5.29 [95% CI: 4.44 to 6.14]), emotional functioning (WMD: 6.19 [95% CI: 5.57 to 6.82]), and cognitive functioning (WMD: 1.02 [95% CI: 0.43 to 1.61]) at 6-month follow-up compared with PDS. CONCLUSIONS:NACT is associated with superior optimal cytoreduction, lower peri-operative morbidity as well as post-surgical mortality, and better QOL compared to initial surgery in patients with advanced EOC. Future research should focus on improving the efficacy of NACT.

Project description:The aim of this study is to evaluate the effects on survival outcomes of the disease burden before interval debulking surgery (IDS), surgical complexity, and residual disease after IDS in advanced-stage ovarian cancer treated with neoadjuvant chemotherapy (NAC). We reviewed the data of 268 epithelial ovarian cancer patients who had received three or four cycles of NAC and undergone optimal resections through IDS. The Kaplan-Meier method and Cox regression analysis were used to assess the effects of disease burden (peritoneal cancer index (PCI)), degree of complexity of surgery (surgical complexity score/s (SCS)), and extent of residual disease. In no residual disease (R0) patients, those with intermediate/high SCS had shorter progression-free survival (PFS; p = 0.001) and overall survival (OS; p = 0.001) than patients with low SCS. An analysis of a subset of patients with R0 and low PCIs showed those with intermediate/high SCS had worse PFS and OS than patients with low SCS (p = 0.049) and OS (p = 0.037). In multivariate analysis, patients with R0 as a result of intermediate/high SCS fared worse than patients whose R0 was achieved by low SCS (PFS hazard ratio (HR) 1.80, 95% CI 1.05-3.10; OS HR 5.59, 95% CI 1.70-18.39). High PCIs at the time of IDS, high SCS, and residual disease signal poor prognoses for patients treated with NAC.

Project description:ObjectivesNeoadjuvant chemotherapy (NACT) versus primary debulking surgery (PDS) for advanced epithelial ovarian cancer (AEOC) remains controversial in the United States. Generalizability of existing trial results has been criticized because of less aggressive debulking procedures than commonly used in the United States. As a result, economic evaluations using input data from these trials may not accurately reflect costs and outcomes associated with more aggressive primary surgery. Using data from an ongoing trial performing aggressive debulking, we investigated the cost-effectiveness and cost-utility of NACT versus PDS for AEOC.MethodsA decision tree model was constructed to estimate differences in short-term outcomes and costs for a hypothetical cohort of 15,000 AEOC patients (US annual incidence of AEOC) treated with NACT versus PDS over a 1-year time horizon from a Medicare payer perspective. Outcomes included costs per cancer-related death averted, life-years and quality-adjusted life-years (QALYs) gained. Base-case probabilities, costs, and utilities were based on the Surgical Complications Related to Primary or Interval Debulking in Ovarian Neoplasms trial. Base-case analyses assumed equivalent survival; threshold analysis estimated the maximum survival difference that would result in NACT being cost-effective at $50,000/QALY and $100,000/QALY willingness-to-pay thresholds. Probabilistic sensitivity analysis was used to characterize model uncertainty.ResultsCompared with PDS, NACT was associated with $142 million in cost savings, 1098 fewer cancer-related deaths, and 1355 life-years and 1715 QALYs gained, making it the dominant treatment strategy for all outcomes. In sensitivity analysis, NACT remained dominant in 99.3% of simulations. Neoadjuvant chemotherapy remained cost-effective at $50,000/QALY and $100,000/QALY willingness-to-pay thresholds if survival differences were less than 2.7 and 1.4 months, respectively.ConclusionsIn the short term, NACT is cost-saving with improved outcomes. However, if PDS provides a longer-term survival advantage, it may be cost-effective. Research is needed on the role of patient preferences in tradeoffs between survival and quality of life.

Project description:OBJECTIVE:To examine outcomes of patients having treatments for newly diagnosed advanced stage low-grade serous ovarian cancer (LGSC). METHODS:We conducted a retrospective case series of women affected by advanced stage (stage IIIB or more) LGSC undergoing surgery in a single oncologic center between January 2000 and December 2017. Survival outcomes were assessed using Kaplan-Meier and Cox models. RESULTS:Data of 72 patients were retrieved. Primary cytoreductive surgery was attempted in 68 (94.4%) patients: 19 (27.9%) had residual disease (RD) >1 cm after primary surgery. Interval debulking surgery (IDS) was attempted in 15 of these 19 (78.9%) patients and the remaining 4 patients having not primary debulking surgery. Twelve out of 19 (63.1%) patients having IDS had RD. After a mean (±standard deviation) follow-up was 61.6 (±37.2) months, 50 (69.4%) and 22 (30.5%) patients recurred and died of disease, respectively. Via multivariate analysis, non-optimal cytoreduction (hazard ratio [HR]=2.79; 95% confidence interval [CI]=1.16-6.70; p=0.021) and International Federation of Obstetrics and Gynecologists (FIGO) stage IV (HR=3.15; 95% CI=1.29-7.66; p=0.011) were associated with worse disease-free survival. Via multivariate analysis, absence of significant comorbidities (HR=0.56; 95% CI=0.29-1.10; p=0.093) and primary instead of IDS (HR=2.95; 95% CI=1.12-7.74; p=0.027) were independently associated with an improved overall survival. CONCLUSION:LGSC is at high risk of early recurrence. However, owing to the indolent nature of the disease, the majority of patients are long-term survivors. Further prospective studies and innovative treatment modalities are warranted to improve patients care.

Project description:ObjectiveThe selection of minimally invasive surgery (MIS) or open laparotomy for ovarian cancer (OC) after neoadjuvant chemotherapy still remains controversial. This study aimed to assess the efficacy and safety of MIS versus open laparotomy following neoadjuvant chemotherapy for advanced OC, so as to provide another option to select optimal surgical procedures for patients with OC.MethodsRelevant literature studies about the risks of progression or mortality between women receiving MIS and open laparotomy for interval debulking surgery (IDS) were searched in the online databases, including PubMed, Embase, and the Cochrane Library with the following keywords: "ovarian neoplasms", "minimally invasive surgical procedures", "laparotomy", and "neoadjuvant therapy". Eligible studies were screened out for further meta-analysis.ResultsSix eligible literature studies, with 643 patients in the MIS group and 2,885 patients in the open laparotomy group, were included in this meta-analysis. No significant differences were detected in the overall survival (OS) of patients with OC who were treated with MIS or open laparotomy [hazard ratio (HR) = 0.85; 95% confidence interval (CI) = 0.59-1.23; heterogeneity: P = 0.051, I2 = 57.6%]. However, the progression-free survival (PFS) was significantly higher in patients with OC treated with MIS than those treated with laparotomy (HR = 0.73; 95% CI = 0.57 to 0.92; heterogeneity: P = 0.276, I2 = 22.4%). The completeness of debulking removal (R0 rate) in the open laparotomy group was not statistically higher compared with the control group (RR = 1.07; 95% CI = 0.93 to 1.23; heterogeneity: P = 0.098, I2 = 52.3%), and no significant differences in residual disease of ≤1 cm (R1) (RR = 1.08; 95% CI = 0.91 to 1.28; heterogeneity: P = 0.330, I2 = 12.6%) and postoperative complications were found between the two groups (RR = 0.72; 95% CI = 0.34 to 1.54; heterogeneity: P = 0.055, I2 = 60.6%). Furthermore, the length of stays in hospital was significantly shorter in patients with OC treated with MIS than those treated with open laparotomy (Standard Mean Difference (SMD) = -1.21; 95% CI = -1.78 to -0.64; heterogeneity: P < 0.001, I2 = 92.7%].ConclusionsFor IDS after NACT in patients with advanced OC, complete cytoreductive surgery with MIS is another feasible and effective choice.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022298519, identifier CRD42022298519.
