Prognostic value of the 2018 FIGO staging system for cervical cancer. Gynecol Oncol 2022; 165:506-513. [PMID: 35346512 DOI: 10.1016/j.ygyno.2022.02.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 02/02/2022] [Accepted: 02/20/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To compare the prognostic performance of the FIGO 2009 and FIGO 2018 staging systems for cervical cancer (CC) in regards to risk stratification, survival and treatment outcome. METHODS A total of 4461 CC patients diagnosed in Denmark during 2005-2018 were identified through the Danish Gynaecological Cancer Database and restaged from the 2009 FIGO to the 2018 FIGO staging system. 5-year survival estimates were made for each group. Also, association between lymphovascular space invasion (LVSI) and lymph node metastasis (LNM) was assesed for tumors with a horizontal spread >7 mm and depth of invasion ≤5 mm. RESULTS Overall, stage migration was observed in 41.4% of our cases due to the introduction of stage IIIC (20.1%), refined tumor size criteria within stage I (76.2%), and use of radiological findings to define stage IV (3.7%). 5-year overall survival increased for all stages except IA2, IIA2, IIIA and IIIB. Restaging of 2009 IB1 to 2018 FIGO resulted in significant stage allocations. Furthermore, an association between LVSI and LNM was observed in squamous cell carcinomas with a depth of invasion of 3-5 mm and a horizontal spread >7 mm (p = 0.03). CONCLUSION The 2018 FIGO staging system provided improved discriminatory ability for stage I and IV. Grouping all patients with positive pelvic or paraortal lymph nodes to stage IIIC led to pronounced heterogenous survival rates within these stages. Lymph node assessment was proven imperative in FIGO 2018 IA2 squamous cell carcinomas with a depth of invasion of 3-5 mm, a horizontal spread >7 mm and LVSI.

Abstract
Aim The influence of sample handling on soluble urokinase plasminogen activator receptor (suPAR) concentrations in serum and EDTA plasma was studied in 16 healthy premenopausal women. Method Blood was collected in dry tubes and tubes containing EDTA and kept at 4°C or 20°C for 1, 3, 8, 24 or 72 hours before processing into serum or EDTA plasma. In addition, serum and EDTA plasma were frozen and thawed 1–8 times. All suPAR measurements were performed by ELISA. Results No significant differences were found between serum or EDTA plasma suPAR concentrations when whole blood samples were kept for 1, 3, 8 or 24 hours. Significantly higher suPAR levels were found in samples kept for 72 hours at 20°C compared to samples processed into serum or EDTA plasma after short-term storage for no more than 24 hours after collection. No significant differences were observed when whole blood was kept at 4°C for up to 72 hours. Repeated freezing and thawing had no significant effect on the serum and EDTA plasma suPAR levels. Conclusion suPAR values in blood samples are dependent on the handling procedures of the samples. All samples of whole blood must be processed into EDTA plasma or serum within 24 hours if kept at 20°C and within 72 hours if kept at 4°C. However, repeated freezing/thawing cycles had no influence on suPAR values in the samples.

Abstract
Objective To examine if the determination of the levels of serological tumor markers at time of relapse had any predictive value for chemoresistance in the second-line treatment of ovarian cancer patients. Methods From a registry of consecutive single-institution patients with epithelial ovarian carcinoma pretreated with paclitaxel plus platinum, we selected 82 patients with (a) solid tumor recurrence, and (b) second-line chemotherapy consisting of topotecan (platinum-resistant disease) or paclitaxel plus carboplatin (platinum-sensitive disease). Stored serum samples were analyzed for the biochemical tumor markers tetranectin, YKL-40, CASA (cancer-associated serum antigen), and CA 125. The serum tumor marker levels at time of relapse were correlated with response status at landmark time after 4 cycles of second-line chemotherapy. Univariate and multivariate logistic regression analyses (chemoresistant vs non-chemoresistant disease) were performed. Results At landmark time, 26% of patients had progression according to the GCIG (Gynecologic Cancer Intergroup) progression criteria. In univariate logistic regression analysis, the tumor markers tetranectin (OR 0.4; 95% CI: 0.2–0.8; p=0.008), YKL-40 (OR 1.8; 95% CI: 1.0–3.3; p=0.045), and CASA (OR 1.8; 95% CI: 1.2–2.7; p=0.007) had predictive value for second-line chemoresistance, whereas serum CA 125 had no predictive value. In a multivariate logistic regression analysis, serum tetranectin and CASA both had independent predictive value for chemoresistance. The combined determination of tetranectin and CASA had a specificity of 90% with 33% sensitivity for the prediction of chemoresistance (area under the receiver operating characteristic curve = 0.78; 95% CI: 0.66–0.91; p=0.001). Conclusion Low serum levels of tetranectin, or high serum levels of CASA or YKL-40, are associated with increased risk of second-line chemoresistance in patients with ovarian cancer.

Obesity and survival among women with ovarian cancer: results from the Ovarian Cancer Association Consortium. Br J Cancer 2015; 113:817-26. [PMID: 26151456 PMCID: PMC4559823 DOI: 10.1038/bjc.2015.245] [Citation(s) in RCA: 97] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2015] [Revised: 06/01/2015] [Accepted: 06/10/2015] [Indexed: 12/15/2022] Open
Abstract
Background: Observational studies have reported a modest association between obesity and risk of ovarian cancer; however, whether it is also associated with survival and whether this association varies for the different histologic subtypes are not clear. We undertook an international collaborative analysis to assess the association between body mass index (BMI), assessed shortly before diagnosis, progression-free survival (PFS), ovarian cancer-specific survival and overall survival (OS) among women with invasive ovarian cancer. Methods: We used original data from 21 studies, which included 12 390 women with ovarian carcinoma. We combined study-specific adjusted hazard ratios (HRs) using random-effects models to estimate pooled HRs (pHR). We further explored associations by histologic subtype. Results: Overall, 6715 (54%) deaths occurred during follow-up. A significant OS disadvantage was observed for women who were obese (BMI: 30–34.9, pHR: 1.10 (95% confidence intervals (CIs): 0.99–1.23); BMI: ⩾35, pHR: 1.12 (95% CI: 1.01–1.25)). Results were similar for PFS and ovarian cancer-specific survival. In analyses stratified by histologic subtype, associations were strongest for women with low-grade serous (pHR: 1.12 per 5 kg m−2) and endometrioid subtypes (pHR: 1.08 per 5 kg m−2), and more modest for the high-grade serous (pHR: 1.04 per 5 kg m−2) subtype, but only the association with high-grade serous cancers was significant. Conclusions: Higher BMI is associated with adverse survival among the majority of women with ovarian cancer.

Evidence for a time-dependent association between FOLR1 expression and survival from ovarian carcinoma: implications for clinical testing. An Ovarian Tumour Tissue Analysis consortium study.

Abstract
BACKGROUND Folate receptor 1 (FOLR1) is expressed in the majority of ovarian carcinomas (OvCa), making it an attractive target for therapy. However, clinical trials testing anti-FOLR1 therapies in OvCa show mixed results and require better understanding of the prognostic relevance of FOLR1 expression. We conducted a large study evaluating FOLR1 expression with survival in different histological types of OvCa. METHODS Tissue microarrays composed of tumour samples from 2801 patients in the Ovarian Tumour Tissue Analysis (OTTA) consortium were assessed for FOLR1 expression by centralised immunohistochemistry. We estimated associations for overall (OS) and progression-free (PFS) survival using adjusted Cox regression models. High-grade serous ovarian carcinomas (HGSC) from The Cancer Genome Atlas (TCGA) were evaluated independently for association between FOLR1 mRNA upregulation and survival. RESULTS FOLR1 expression ranged from 76% in HGSC to 11% in mucinous carcinomas in OTTA. For HGSC, the association between FOLR1 expression and OS changed significantly during the years following diagnosis in OTTA (Pinteraction=0.01, N=1422) and TCGA (Pinteraction=0.01, N=485). In OTTA, particularly for FIGO stage I/II tumours, patients with FOLR1-positive HGSC showed increased OS during the first 2 years only (hazard ratio=0.44, 95% confidence interval=0.20-0.96) and patients with FOLR1-positive clear cell carcinomas (CCC) showed decreased PFS independent of follow-up time (HR=1.89, 95% CI=1.10-3.25, N=259). In TCGA, FOLR1 mRNA upregulation in HGSC was also associated with increased OS during the first 2 years following diagnosis irrespective of tumour stage (HR: 0.48, 95% CI: 0.25-0.94). CONCLUSIONS FOLR1-positive HGSC tumours were associated with an increased OS in the first 2 years following diagnosis. Patients with FOLR1-negative, poor prognosis HGSC would be unlikely to benefit from anti-FOLR1 therapies. In contrast, a decreased PFS interval was observed for FOLR1-positive CCC. The clinical efficacy of FOLR1-targeted interventions should therefore be evaluated according to histology, stage and time following diagnosis.

Abstract
Low-moderate risk alleles that are relatively common in the population may explain a significant proportion of the excess familial risk of ovarian cancer (OC) not attributed to highly penetrant genes. In this study, we evaluated the risks of OC associated with common germline variants in five oncogenes (BRAF, ERBB2, KRAS, NMI and PIK3CA) known to be involved in OC development. Thirty-four tagging SNPs in these genes were genotyped in approximately 1800 invasive OC cases and 3000 controls from population-based studies in Denmark, the United Kingdom and the United States. We found no evidence of disease association for SNPs in BRAF, KRAS, ERBB2 and PIK3CA when OC was considered as a single disease phenotype; but after stratification by histological subtype, we found borderline evidence of association for SNPs in KRAS and BRAF with mucinous OC and in ERBB2 and PIK3CA with endometrioid OC. For NMI, we identified a SNP (rs11683487) that was associated with a decreased risk of OC (unadjusted P(dominant)=0.004). We then genotyped rs11683487 in another 1097 cases and 1792 controls from an additional three case-control studies from the United States. The combined odds ratio was 0.89 (95% confidence interval (CI): 0.80-0.99) and remained statistically significant (P(dominant)=0.032). We also identified two haplotypes in ERBB2 associated with an increased OC risk (P(global)=0.034) and a haplotype in BRAF that had a protective effect (P(global)=0.005). In conclusion, these data provide borderline evidence of association for common allelic variation in the NMI with risk of epithelial OC.

Preoperative serum tetranectin, CA125 and menopausal status used as single markers in screening and in a risk assessment index (RAI) in discriminating between benign and malignant ovarian tumors. Gynecol Oncol 2009; 113:221-7.

Abstract
OBJECTIVES To improve the poor survival in ovarian cancer (OC) patients, the research has been focused on new OC markers. One aim is to find markers to identify the cancers in early preclinical stages by screening. Another aim is to find new diagnostic markers, which may select patients at high risk for OC for quick referral to highly specialized centers in gynecologic oncology. These aims were addressed in the present study by evaluating serum tetranectin (TN) and serum CA125 on a large number of pre- and postmenopausal women with ovarian tumors and controls. METHODS The potential ability of the markers to discriminate between the four groups (208 benign ovarian tumor, 153 borderline ovarian tumor (BOT), 445 OC and 1333 age matched controls) in OC screening was examined. We also constructed a risk assessment index (RAI) for discrimination between tumor groups based on these variables and menopausal status. RESULTS Highly significant differences in both TN and CA125 levels were found between all the four groups as well as between the different FIGO stages of OC patients. A very high probability of having OC or a benign tumor, respectively, was predicted by the RAI. CONCLUSIONS In the case-control part of the study, we found that TN and CA125 deserve to be validated on pre-clinical samples by inclusion in future marker panels. The RAI is also a potential new candidate for a diagnostic tool for selecting patients at high risk for having OC; hence it deserves further evaluation in a prospective clinical study.

Abstract
OBJECTIVE To prospectively identify combined PET/CT predictors of incomplete/suboptimal primary cytoreduction in advanced ovarian cancer. METHODS From September 2004 to March 2007, 179 patients with a Risk of Malignancy Index (RMI) >150 based on serum CA-125, ultrasound examinations and menopausal state, underwent PET/CT within 2 weeks prior to standard surgery/debulking of a pelvic tumor. Ten PET/CT features were identified and evaluated as predictors of cytoreduction in 54 patients with advanced ovarian cancer. RESULTS Complete cytoreduction (no macroscopic residual disease) was achieved in 35% and optimal cytoreduction (<1 cm residual disease) was achieved in 56%. Using univariate analysis, predictors of incomplete cytoreduction were large bowel mesentery implants (LBMI) (P<0.003), pleural effusion (P<0.009), ascites (P<0.009) and peritoneal carcinosis (P<0.01). LBMI (P<0.03) and ascites (P<0.05) were also predictors of suboptimal cytoreduction. Using multivariate analysis, LBMI was the only independent predictor of incomplete cytoreduction (P=0.004) and no predictor of suboptimal cytoreduction was found. CONCLUSION PET/CT predictors of cytoreduction were found. But they should not be used to withhold patients form primary cytoreductive surgery. We suggest PET/CT as a supplementary image modality prior to surgery in primary OC patients whenever accurate and comprehensive preoperative evaluation of primary tumor and metastases is desired.

Abstract
5057 Background: Previously we discovered seven serum biomarkers: ITIH4, transthyretin, ApoA1, CTAPIII, hepcidin, transferrin, and SAA, for the detection of ovarian cancer. They are fragments, cleavages, or PTMs of circulating proteins that are difficult to measure by conventional immunoassays. Using optimzed mass spectrometry assays, we evaluated these biomarkers in a large-scale multi-center study. Methods: A total of 607 serum samples from five sites were analyzed using SELDI TOF-MS protocols optimized for the seven biomarkers. They included 234 women with benign gynecologic diseases, and 373 patients with invasive epithelial ovarian cancer (101 early stage, 231 late stage, and 40 stage unknown). Among them, 165 benigns and 228 cancers had a CA125 available at time of analysis. The median and quartiles of CA125 for benign, early stage, and late or unknown stage were 26/11/57 IU, 80/22/434 IU, and 234/40/1114 IU, respectively. The biomarkers were assessed individually using the Mann-Whitney U Test. A linear composite index was derived in an unsupervised fashion using data from one site and then calculated for the remaining data using the fixed formula. ROC curve analyses were performed on data from individual sites and all sites combined. Results: All seven biomarkers individually demonstrated statistically significant differentiating power, and the majority had p-value<0.00001. AUCs of the composite index in ROC analyses for the six sites were 0.602, 0.566, 0.821, 0.813, and 0.592 in detecting cancer at all stages from benign. On the combined data, the differences in AUC between the index and CA125 were not statistically significant for the detection of cancer at all stages (AUC=0.706 vs. 0.725) or early stages only (AUC=0.534 vs. 0.653). However, the index did better at the high-sensitivity range. At a fixed sensitivity of 86%, the specificity of the index was 34% (77/226) compared to CA125 at 26% (42/163). For early stage cases, at a fixed sensitivity of 84%, the specificity of the index was 24% (55/226) compared to CA125 at 14%% (22/163). Conclusions: We validated seven previously discovered biomarkers, individually and in combination. Prospective studies and assay development are under way to further characterize their clinical utility. [Table: see text]

Abstract
AIM The objective was to analyse the impact of secondary cytoreductive surgery in patients with recurrent ovarian carcinoma. METHODS Retrospective review of 572 consecutive patients with primary ovarian carcinoma. Thirty-eight patients with intraabdominal/pelvic recurrence consisted the study group. Clinical variables affecting tumour resectability and survival were evaluated. RESULTS Complete tumour resection was obtained in 42% of patients. A solitary tumour recurrence was independently associated with complete tumour resection (p=0.009). Median survival for patients with complete and incomplete tumour resection was 51.8 and 19.9 months. The parameter, residual tumour, was found independently correlated with survival after the relapse surgical procedure (p=0.02). However, including also the parameter, number of relapse tumour sites, in the multivariate analysis, the parameter, residual tumour, was no longer significantly associated with survival. CONCLUSIONS Complete tumour resection following secondary cytoreductive surgery is associated with improved survival in selected groups of patients with recurrent ovarian cancer. However, other clinical factors than surgical cytoreduction are of considerable significance in determining the outcome of the salvage treatment.

Abstract
Recent studies indicate that cancer antigen 125 (CA125) response criteria tend to overestimate a tumour reduction measured by standard WHO response criteria in recurrent epithelial ovarian carcinoma. The aim of the study was to validate the recently introduced GCIG (The Gynaecological Cancer Intergroup) CA125 response criteria in predicting a tumour response measured by WHO (World Health Organization) criteria. Changes in CA125 levels (GCIG criteria) were retrospectively compared with alterations in the tumour load (WHO criteria) during second-line chemotherapy with topotecan or paclitaxel-platinum in 124 consecutive patients with recurrent or refractory disease. In patients assessable by both response criteria (n=72), the overall response rate using GCIG CA125 criteria was 57% (95% confidence interval (CI): 45-69%) and significantly higher than the response rate of 39% (95% CI: 28-51%) using WHO response criteria (P=0.045). The GCIG CA125 criteria had a sensitivity of 96% (95% CI: 82-100%), a specificity of 68% (95% CI: 52-81%) and an accuracy of 79% (95% CI: 68-88%) in predicting a response measured by WHO criteria. In conclusion, the GCIG CA125 response criteria seem to overestimate a tumour response by WHO criteria when monitoring the efficacy of second-line chemotherapy with topotecan or paclitaxel-platinum in patients with epithelial ovarian carcinoma.

Abstract
OBJECTIVE The purpose of the study was to evaluate the treatment results and toxicity of a retreatment regimen of paclitaxel and carboplatin in patients with ovarian cancer relapse. METHODS A retrospective analysis of 241 consecutive patients with primary epithelial ovarian cancer receiving paclitaxel and a platinum analogue as first-line treatment was performed. Relapse treatment of platinum-sensitive patients consisted of paclitaxel (175 mg/m(2)) over 3 h followed by carboplatin at an area under the concentration-time curve of 5, repeated every 3 weeks. RESULTS Forty-three patients with relapse were treated with paclitaxel and carboplatin after a median progression-free interval from the end of first-line chemotherapy of 15.8 months (range 6.0-41.7 months). In patients with evaluable disease the overall response rate was 84% (95% CI: 68.0-93.8%). The progression-free survival and overall survival from start of relapse treatment were a median of 9.7 months (range 1.4-26.9 months) and 13.1 months (range 4.5-35.5 months), respectively. In a multivariate Cox analysis independent prognostic factors for progression-free survival after first relapse were response to relapse treatment (P = 0.002, hazard ratio = 13.9) and time to first recurrence (P = 0.016, hazard ratio = 0.167). The planned treatment was accomplished by 67% of patients. Grade 4 neutrocytopenia over 1 week was observed in 9.3% of patients. Grade 1-2 peripheral neuropathy was reported in 30% of patients. Only 1 patient had her paclitaxel dose attenuated because of grade 4 neuropathy. CONCLUSION Retreatment with paclitaxel and carboplatin in patients with platinum-sensitive epithelial ovarian cancer relapse yielded a high response rate and encouraging progression-free survival and overall survival. Paclitaxel-carboplatin reinduction therapy is generally well tolerated and the toxicity is manageable.
