Huang T, Lu F. Prognostic nomogram for predicting the overall survival rate of patients with uterine clear-cell carcinoma: Based on SEER database. Int J Gynaecol Obstet 2024; 166:707-717. [PMID: 38444201 DOI: 10.1002/ijgo.15456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 02/14/2024] [Accepted: 02/20/2024] [Indexed: 03/07/2024]
Abstract
OBJECTIVE To evaluate the risk factors for uterine clear-cell carcinoma (UCCC) and construct nomograms predicting 1-, 3-, and 5-year overall survival rates of patients with UCCC. METHODS The demographic and clinical information of 1674 patients diagnosed with UCCC between 2004 and 2015, including age, race, marital status, tumor size, American Joint Committee on Cancer (AJCC) stage, and details of surgery and radiotherapy/chemotherapy, was collected from the Surveillance, Epidemiology, and End Results (SEER) database. After excluding patients with unknown AJCC stage, race, marital status, or lymph node information, 1469 patients remained. Risk factors were determined using univariate and multivariate analyses, and nomograms were developed to predict 1-, 3-, and 5-year overall survival of UCCC. Various indicators were used to evaluate the performance of the nomogram, such as the C-index, net classification improvement (NRI) and decision curve analysis (DCA). RESULTS Age, log odds of positive lymph nodes, AJCC stage, surgery status, and chemotherapy status were independent risk factors for UCCC. The C-indexes of the training group and AJCC stage groups were 0.771 and 0.697, respectively. The results for the area under the receiver operating characteristics curve, NRI, and calibration curves indicated that the nomogram had good predictive ability. DCA revealed that the nomogram had greater clinical applicability than AJCC stage alone. Internal validation using the validation cohort also demonstrated that this nomogram had good predictive performance. CONCLUSION A new nomogram comprising a combination of demographic and clinical characteristics provided better survival predictions than the AJCC staging system alone, which will facilitate prognostic assessments and clinical decision-making.

J Cancer Res Clin Oncol 2023; 149:14475-14492. [PMID: 37567988 DOI: 10.1007/s00432-023-05174-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 07/09/2023] [Indexed: 08/13/2023]
Abstract
PURPOSE To investigate the prognostic indicators, develop and verify nomograms for predicting overall survival (OS) and cancer-specific survival (CSS) in elderly patients with uterine serous carcinoma (USC). METHODS Data of eligible USC patients aged ≥ 65 years from 2004 to 2015 in the Surveillance, Epidemiology and End Results (SEER) database were collected for retrospective analysis. X-tile software was used to assess the optimal cut-off values. Univariate and multivariate Cox regression analyses were performed to explore the prognostic factors. Nomograms were developed to predict the probability of 1-, 3- and 5-year OS and CSS. Concordance indexes (c-index), receiver operating characteristic analysis and calibration curves were used to evaluate the model. Decision curve analysis (DCA) was introduced to examine the clinical value of the models. RESULTS Age, Federation International of Gynecology and Obstetrics stage, N stage, tumor size, number of lymph nodes resected, and adjuvant therapy were independent prognostic factors for OS and CSS. The C-indexes were 0.736 (OS), 0.754 (CSS) in the training set and 0.731 (OS), 0.759 (CSS) in the validation set. The area under the curve (AUCs) of OS and CSS for 1-, 3-, and 5-years all exceeded 0.75. The calibration plots for the probability of survival were in good agreement. As shown in DCA curves, the nomograms showed better discrimination power and higher net benefits than the 6th American Joint Committee on Cancer staging system. CONCLUSIONS The nomograms constructed based on prognostic risk factors could individually predict the prognosis of elderly USC patients and provide a reference for clinical decision-making.

Conditional estimates for uterine serous cancer: Tools for survivorship counseling and planning. Gynecol Oncol 2022; 166:90-99. [PMID: 35624045 DOI: 10.1016/j.ygyno.2022.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 05/06/2022] [Accepted: 05/14/2022] [Indexed: 11/04/2022]
Abstract
OBJECTIVES Develop conditional survival and risk-assessment estimates for uterine serous carcinoma (USC) overall and stratified by stage as tools for annual survivorship counseling and care planning. METHODS Patients in the National Cancer Data Base diagnosed between 2004 and 2014 with stage I-IV USC were eligible. Individuals missing stage or survival data or with multiple malignancies were excluded. Five-year conditional survival was estimated using the stage-stratified Kaplan-Meier method annually during follow-up. A standardized mortality ratio (SMR) estimated the proportion of observed to expected deaths in the U.S. adjusted for year, age, and race. The relationships between prognostic factors and survival were studied using multivariate Cox modeling at diagnosis and conditioned on surviving 5-years. RESULTS There were 14,575 participants, including 43% with stage I, 8% with stage II, 29% with stage III, and 20% with stage IV USC. Five-year survival at diagnosis vs. after surviving 5-years was 52% vs. 75% overall, 77% vs. 81% for stage I, 57% vs. 72% for stage II, 40% vs. 66% for stage III, and 17% vs. 60% for stage IV USC, respectively (P < 0.0001). Incremental improvements in 5-year conditional survival and reductions in SMR tracked with annual follow-up and higher stage. The adjusted risk of death at diagnosis vs. after surviving 5-years was 1.15 vs. 1.40 per 5-year increase of age, 1.26 vs. 1.68 for Medicaid insurance, 3.92 vs. 2.48 for stage III disease, and 6.65 vs. 2.79 for stage IV disease, respectively (P < 0.0001). CONCLUSION In USC, the evolution of conditional survival permits annual reassessments of prognosis to tailor survivorship counseling and care planning.

[PMID: 34934360 PMCID: PMC8684396 DOI: 10.2147/cmar.s337271] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 12/07/2021] [Indexed: 12/25/2022] Open
Abstract
Purpose Programmed death-ligand 1 (PD-L1) has been widely used as a prognostic biomarker and an immunotherapeutic target in numerous cancers, but information on the clinical significance of its expression in endometrial serous carcinoma (ESC) is largely lacking. Here, we evaluate the predictive value of PD-L1 expression in ESC. Materials and Methods A total of 79 cases of ESC accessioned between January 2003 and September 2015 were selected for further analysis. PD-L1 expression was evaluated in whole tissue sections of these cases by using the tumor proportion score (TPS, cut-off 1%) and combined positive score (CPS, cut-off 1) scoring methods. Results Overall, there was a heterogeneous expression of PD-L1, focal or patchy, in ESCs. PD-L1 positivity was observed in 43.0% of ESCs by TPS and 73.4% of ESCs by CPS. Kaplan–Meier survival analysis showed that patients with PD-L1-positive tumors suffered significantly worse OS and PFS, when compared with PD-L1 negative tumors (log-rank p = 0.037 and p = 0.003, respectively). In contrast, PD-L1 positivity by CPS within the ESC cases showed no statistical significance for OS and PFS (log-rank p = 0.720 and p = 0.928, respectively). Multivariate Cox analysis showed that PD-L1 positivity by TPS was significantly associated with PFS (HR = 1.921, p = 0.039) but not OS (HR = 1.229, p = 0.631). Conclusion PD-L1 expression is frequently found in ESC, suggesting a potential role of the PD-1/PD-L1 pathway as a potential therapeutic target for these tumors. PD-L1 expression by TPS also serves as a negative prognostic marker in ESC and implies an unfavorable outcome.

Abstract
OBJECTIVE To evaluate factors impacting survival outcomes in patients with uterine serous carcinoma (USC). METHODS Data of consecutive patients diagnosed with USC undergoing surgery between 2000 and 2020 at Fondazione IRCCS Istituto Nazionale Tumori of Milan (Italy) were reviewed. Progression-free (PFS) and overall survival (OS) outcomes were evaluated using Kaplan-Meier and Cox proportional hazard models. RESULTS Records of 147 consecutive patients meeting the inclusion criteria were analyzed. Stage distribution was: 67 (45.6%) patients with early-stage with uterine confined disease and 80 (54.4%) with advanced stages disease. Minimally invasive surgery was performed in 43 patients (29.5%). The median follow-up period was 78.6 months (IQ range = 35.7-117.3 months). The overall recurrence rate was 41% (60 patients): 19/67 patients (28.4%) with early-stage disease and 41/80 patients (51.3%) with advanced stage. The 5-year PFS rate was 35.0% (95% confidence interval [CI]: 27.5-44.7%). In multivariate analysis, age, BMI, depth of myometrial invasion, cytology, and optimal cytoreduction with postoperative residual tumor absent significantly impacted on PFS. The 5-year OS rates were 46.5% (95% CI: 38.1-56.8). The result of multivariate analysis showed that there was significant difference in OS based only on optimal cytoreduction and accuracy of retroperitoneal surgery. CONCLUSIONS In apparent early-stage USC, peritoneal and retroperitoneal staging allows to identify patients with disease harboring outside the uterus. Optimal cytoreduction is the most significant prognostic factor. Further collaborative studies are warranted in order to improve outcomes of USC patients.

Abstract
BACKGROUND The prognostic factors of uterine serous carcinoma (USC) vary among studies, and there is no report of Chinese USC patients. OBJECTIVE The aim of this study was to investigate the clinicopathological characteristics and prognostic factors in Chinese patients with USC. METHODS Patients with USC from 13 authoritative university hospitals in China and treated between 2004 and 2014 were retrospectively reviewed. Three-year disease-free survival rate (DFSR), cumulative recurrence, and cumulative mortality were estimated by Kaplan-Meier analyses and log-rank tests. Multivariate Cox regression analysis was used to model the association of potential prognostic factors with clinical outcomes. RESULTS Data of a total of 241 patients were reviewed. The median follow-up was 26 months (range, 1-128 months). Median age was 60 years (range, 39-84 years), and 58.0% had stages I-II disease. The 3-year DFSR and cumulative recurrence were 46.8% and 27.7%. Advanced stage (III and IV) (P = 0.004), myometrial invasion (P = 0.001), adnexal involvement (P < 0.001), lymph node metastasis (P = 0.025), and positive peritoneal cytology (P = 0.007) were independently associated with 3-year DFSR. Advanced stage (P = 0.017), myometrial invasion (P = 0.008), adnexal involvement (odds ratio, 2.987; P = 0.001), lymph node metastasis (P = 0.031), and positive peritoneal cytology (P = 0.001) were independently associated with the cumulative recurrence. Myometrial invasion (P = 0.004) and positive peritoneal cytology (P = 0.025) were independently associated with 3-year cumulative mortality. CONCLUSIONS Peritoneal cytology and myometrial invasion could be independent prognostic factors for 3-year DFSR, cumulative recurrence, and cumulative mortality of patients with USC. Prospective studies are needed to confirm these results.

Abstract
Objectives The objectives of this study were to analyze clinicopathological features and to investigate the prognostic determinants in patients with uterine papillary serous carcinoma (UPSC). Materials and methods A cohort of 106 UPSC patients diagnosed and treated at Peking Union Medical College Hospital between 2000 and 2016 were retrospectively reviewed. The Kaplan-Meier method and Cox regression analysis were used for survival analysis. Differences between categorical data were calculated by using the chi-squared test. Results The median follow-up was 29.0 months (range =2-170 months), with an overall recurrence rate of 35.8%. The coincidence rate between preoperative endometrial sampling and postoperative definitive pathology of hysteroscopy group was significantly higher than that of the dilation and curettage group (88.5% vs 65.0%, P=0.019). Adjuvant therapy-treated patients with stage I UPSC experienced significantly fewer recurrences than those receiving observation (P=0.003). Patients with advanced-stage UPSC who received combination therapy demonstrated a lower risk of local recurrence compared with those who received chemotherapy alone with a borderline significance (P=0.051). Elevated serum cancer antigen 125 level was associated with advanced-stage disease and recurrence (P<0.001). In multivariate analysis, tumor stage and optimal cytoreduction were independent predictors of survival. In substage analysis, complete surgical staging was associated with better overall survival (OS; yes vs no, HR: 0.05 [95% CI: 0.01-0.51], P=0.037) in patients with stage I UPSC. As for advanced stage, paclitaxel-platinum chemotherapy regimen and optimal cytoreduction were independent favorable prognostic factors for progression-free survival (paclitaxel-carboplatin [TC] vs other; HR =0.38, P=0.010; yes vs no, HR =0.45, P=0.032) and OS (TC vs other, HR =0.38, P=0.022; yes vs no, HR =0.54, P=0.013). Conclusion In patients with stage I UPSC, complete staging was associated with better OS, and therefore, it should be performed in all patients. Tumor stage and optimal cytoreduction are the most significant prognostic factors. Recurrence can be improved in stage I patients treated with adjuvant therapy and in patients with advanced-stage disease treated with combined therapy. TC regimen may be the preferred regimen for chemotherapy.
