Clinicopathological Features, Prognostic Factors, Survival Trends, and Treatment of Malignant Ovarian Germ Cell Tumors: A SEER Database Analysis

Objective: The aim of this study was to investigate the clinicopathological prognostic factors of malignant ovarian germ cell tumors (MOGCT) and evaluate the survival trends of MOGCT by histotype. Methods: We extracted data on 1,963 MOGCT cases diagnosed between 2000 and 2014 from the Surveillance, Epidemiology, and End Results (SEER) database and the histological classification of MOGCT, including 5 categories: dysgerminoma, embryonal carcinoma (EC), yolk sac tumor, malignant teratoma, and mixed germ cell tumor. We examined overall and disease-specific survival of the 5 histological types. Kaplan-Meier and Cox proportional hazards regression models were used to estimate survival curves and prognostic factors. We also estimated survival curves of MOGCT according to different treatments. Results: There was a significant difference in prognosis among different histological classifications. Age, histotype, grade, SEER stage, and surgery were independent prognostic factors for survival of patients with MOGCT. For all histotypes, 1-, 3-, and 5-year survival rate estimates were >85%, except for EC, which had the worst outcomes at 1 year (55.6%), 3 years (44.4%), and 5 years (33.3%). In the distant SEER stage, both chemotherapy and surgery were associated with improved survival outcomes compared with surgery- and chemotherapy-only groups. Conclusions: Dysgerminoma patients had the most favorable outcomes, whereas EC patients had the worst survival. A young age, low grade, and surgery were all significant predictors for improved survival. In contrast, a distant SEER stage was a risk factor for poor survival. Chemotherapy combined with surgery contributed to longer survival times of patients with MOGCT in the distant SEER stage.

Abstract BACKGROUND Limited data is available in intracranial nongerminomatous germ cell tumors (NGGCTs) in Chinese population. Here we aimed to retrospectively assess the clinical-pathological and prognostic factors of NGGCTs in a single large institution in China. METHODS From June 2003 to December 2018, 111 consecutive NGGCTs were treated in Guangdong Sanjiu Brain Hospital, China. RESULTS The median follow-up was 36.2 months (range, 1.2 to 131.2 months). Three-year EFS and OS for 111 NGGCTs patients were 78.5%±4.5% and 82.8%±4.0%, respectively. 98 patients received CSI plus boost yielded better survival than those who received reduced-volume radiotherapy or no radiotherapy (3y OS, 86.7% vs. 51.4%, p=0.007). Patients had at least four cycles of chemotherapy were strongly associated with improved 3-year OS, compared to those received less than 4 cycles (94.1% vs. 63.6%, p＜0.001). There was no significant difference in survival of patients stratified by age, surgery, hydrocephalus, as well as tumor diameter. Multivariate analysis identified chemotherapy cycles less than 4 was the only prognostic factor that conferring a worse OS (p=0.003). Patients both received CSI and at least 4 courses of chemotherapy were correlated with lower incidence of relapse (p=0.044). CONCLUSIONS Multimodal approach including CSI and enough courses of chemotherapy was effective and should be recommended for the treatment of newly diagnosed NGGCTs in Chinese population.

Objective:To compare the survival of patients with bilateral versus unilateral malignant ovarian germ cell tumors (OGCT).Methods:Patients with a diagnosis of OGCT were identified from the Surveillance, Epidemiology, and End Results Program for the period 1988 to 2006 and were divided into bilateral and unilateral subgroups. Only surgically treated patients were included. Histologic types were grouped into dysgerminoma, malignant teratoma, and mixed germ cell tumors with pure nondysgerminoma cell tumors. Statistical analysis using Wilcoxon rank sum test, Kaplan-Meier survival methods, and Cox proportional hazards regression model were performed.Results:In 1529 patients with OGCT, 1463 (95.7%) were unilateral and 66 (4.3%) were bilateral. Bilaterality was more common with dysgerminomas (6.5%) and mixed germ cell tumors with pure nondysgerminoma cell tumors (6.25%) than with immature teratomas (1.7%),P< 0.001. Most OGCT (67.3%) were stage I. Bilateral OGCT were more likely than unilateral tumors to be associated with advanced-stage disease (FIGO III and IV, 41% vs 20%,P< 0.04). Overall 5-year survival was 93.6% for unilateral OGCT and 80.7% in bilateral OGCT,P< 0.001. In multivariate analysis, bilaterality was not an independent predictor of survival when controlling for age, histology, stage, and surgical staging (hazard ratio, 1.3; 95% confidence interval, 0.7-2.5;P= 0.40).Conclusions:Compared with unilateral tumors, bilateral OGCT are more often associated with advanced-stage disease, high-risk histology, and poor survival. When other prognostic factors are accounted for, bilaterality was not an independent prognostic predictor of survival.

Abstract Background: Prognostic factors in pneumonectomy (PN) are not yet fully defined. This study is to analyze and evaluate long-term survival after PN for non-small cell lung cancer (NSCLC). Methods: We obtained data from the Surveillance, Epidemiology, and End Results (SEER) database for patients who underwent PN between 2004 and 2015. In order to reduce bias and imbalance, propensity score matching (PSM) analysis was performed. We used Kaplan-Meier curves to estimate overall survival (OS), performed univariate and multivariate Cox proportional hazards regression analyses to identify independent prognostic factors for OS, and applied the Cox proportional hazards model to create a forest plot. Results: A total of 1557 PN patients from the SEER database were included. The patients were grouped according to the side of PN. Before matching, OS was worse after right PN (hazard ratio [HR]: 1.303; 95% confidence interval [CI] 1.133-1.498; P<0.001), but survival difference between groups was not significant after matching (HR: 1.061; 95% CI 0.912-1.235; P=0.443). Regression analysis revealed that age, grade, N-stage, radiotherapy, and chemotherapy were independent predictors of OS (P<0.05). Chemotherapy was associated with improved OS (HR: 0.709; 95% CI 0.609-0.825; P<0.001), but radiotherapy was associated with increased risk of death in OS (HR: 1.268; 95% CI 1.061-1.561; P=0.009). On the forest plot, patients with primary overlapping lesions had better OS (HR: 0.684; 95% CI 0.497-0.941; P=0.020) in left, vs right, PN; patients diagnosis during 2004 to 2007 had lower OS (HR: 0.576; 95% CI 0.346-0.960; P=0.034) for left PN vs right PN.Conclusions: Laterality was not a significant prognostic factor for long-term survival after PN for NSCLC. Chemotherapy was a significant independent predictor of improved OS, while radiotherapy appeared to be a negative prognostic factor with increased risk of death in OS.

AbstractHepatectomy and transplantation are the main surgical therapies for HCC patients, and radiotherapy or chemotherapy is often used as adjuvant treatment. Researches have evaluated the independent predictors of HCC, but evidence for factors predicting the efficacy of chemotherapy is rare. Patients diagnosed with HCC between 2010 and 2015 from the SEER database were included and randomly divided into non-chemotherapy and chemotherapy groups. The predictors of CSS and OS were analyzed with the Cox proportional-hazards regression model and Fine and Gray’s competing risk model. Although there was no significant difference in survival analysis between the chemotherapy and non-chemotherapy groups, the cumulative cancer-specific mortality of most HCC patients was decreased in the chemotherapy group. AJCC stage, tumor size, grade, surgery and radiotherapy were predictors of OS and CSS in the non-chemotherapy group, while AJCC stage, tumor size, AFP, grade and surgery in the chemotherapy group. Surgery combined with chemotherapy was applicable to all AJCC stage patients. Surgery was the major treatment option for patients in AJCC I and AJCC II stage, and chemotherapy in AJCC III and AJCC IV stage. In conclusion, the study provided population-based estimates of the prognostic factors in HCC patients with or without chemotherapy.

Abstract Background Bladder cancer is the most common cancer in the urinary system and the fourth most common cancer in males. This study aimed to examine differences in the survival of bladder cancer patients of different ethnicities. Method We used the SEER database to obtain data pertaining to bladder cancer patients from 2010 to 2015. Univariate and multivariate Cox proportional hazards regression analyses were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between ethnicity and death. Kaplan–Meier survival and nomogram analyses were used to compare survival differences among patients with different ethnicities. Results Among 101,364 bladder cancer patients, 90,910 were white, 5893 were black, 337 were American Indian/Alaska Native (AIAN), and 4224 were Asian or Pacific Islander (API). Our multivariate analysis identified differences between different ethnicities. Compared to the API group, the AIAN (HR = 1.31, 95% CI = 1.09–1.57, P < 0.001), black (HR = 1.56, 95% CI = 1.46–1.67, P < 0.001), and white (HR = 1.18, 95% CI = 1.12–1.25, P < 0.001) groups showed lower survival probabilities. Based on data from all Kaplan–Meier survival curves, there was no significant difference in survival between the black and AIAN groups, but the survival of these two races was worse than that of the white and API groups. We also used a nomogram to estimate patient survival and validated its predictive value. Conclusion Our results suggest that ethnic differences exist in patients with bladder cancer, that the survival of black and AIAN bladder cancer patients is worse than that of other ethnicities and that the survival of API patients is the best. The significant prognostic factors of overall survival, which include age, sex, ethnicity, summary stage, American Joint Committee on Cancer stage, surgery type, and histologic type, should be applied to bladder cancer patient prognostication.

BackgroundAlbumin-to-alkaline phosphatase ratio (AAPR) has been reported as a novel prognostic predictor for numerous solid tumors. We aimed to assess the prognostic role of preoperative AAPR in surgically resectable esophageal squamous cell carcinoma (ESCC) by a propensity score matching (PSM) analysis with predictive nomograms.MethodsOur study was conducted in a single-center prospective database between June 2009 and December 2012. Kaplan-Meier analysis was used to distinguish the difference in survival outcomes between patients stratified by an AAPR threshold. Multivariable Cox proportional hazards regression model was finally generated to specify independent prognostic markers for the entire and PSM cohorts.ResultsA total of 497 patients with ESCC were included in this study. An AAPR of 0.50 was determined as the optimal cutoff point for prognostic outcome stratification. Patients with AAPR<0.50 had significantly worse overall survival (OS), and progression-free survival (PFS) compared to those with AAPR≥0.50 (Log-rank P<0.001). This significant difference remained stable in the PSM analysis. Multivariable analyses based on the entire and PSM cohorts consistently showed that AAPR<0.50 might be one of the most predominant prognostic factors resulting in unfavorable OS and PFS of ESCC patients undergoing esophagectomy (P<0.001). The nomograms consisting of AAPR and other independent prognostic factors further demonstrated a plausible predictive accuracy of postoperative OS and PFS.ConclusionAAPR can be considered as a simple, convenient and noninvasive biomarker with a significant prognostic effect in surgically resected ESCC.

384 Background: The International Germ Cell Consensus (IGCC) classification is based on primary tumor localization, presence of non-pulmonary visceral metastases, and serum tumor marker levels, not the general condition of patients. The present study aimed to identify novel prognostic factors for nonseminomatous germ cell tumors (NSGCTs) with IGCC intermediate or poor prognosis. Methods: We retrospectively analyzed 399 patients with germ cell tumors (GCT) treated at Tohoku University Hospital between 1979 and 2011. Of these, 52 and 61 patients with NSGCTs were classified as having intermediate and poor prognosis, respectively. Several clinical parameters were reviewed, including age, IGCC prognosis group, kind of induction chemotherapy, and extra-scrotal symptoms at presentation. Extra-scrotal symptoms were defined as symptoms other than scrotal swelling, such as abdominal pain, lumbago, and dyspnea. Survival was estimated using the Kaplan-Meier method. A Cox proportional hazards model was used to assess potential predictors of outcome. Results: The median age of the 113 patients was 30. Median length of follow-up was 57 months. At presentation, 12 (23%) patients with intermediate prognosis and 32 (52%) patients with poor prognosis had extra-scrotal symptoms. In the intermediate prognosis group, the five year overall survival (OS) of patients with extra-scrotal symptoms was significantly worse than that of patients without symptoms (95% vs. 63%, p= 0.0008), but there was no significant difference in five year OS between patients with and without extra-scrotal symptoms in the poor prognosis group (60% vs. 66%, p= 0.265). On multivariate analysis, the presence of extra-scrotal symptoms (hazard ratio [HR] = 2.48, p= 0.0184) and induction chemotherapy not including etoposide (HR = 12.0, p< 0.0001) were independent predictors of inferior OS. Conclusions: The presence of extra-scrotal symptoms was associated with inferior OS, particularly in patients with intermediate prognosis. Intermediate-prognosis patients with extra-scrotal symptoms should be recognized as having poor prognosis.

Purpose: The survival times of glioblastoma (GB) patients after the standard therapy including safe maximal resection followed by radiotherapy plus concomitant and adjuvant temozolomide are heterogeneous. In order to define a simple, reliable method for predicting whether patients with isocitrate dehydrogenase (IDH)-wildtype GB treated with the standard therapy will be short- or long-term survivors, we analyzed the correlation of preoperative blood counts and their combined forms with progression-free survival (PFS) and overall survival (OS) in these patients. Methods: Eighty-five patients with primary IDH-wildtype GB treated with the standard therapy between 2012 and 2019 were analyzed retrospectively. Cox proportional hazards models and Kaplan–Meier analysis were used to investigate the survival function of preoperative hematological parameters. Results: Preoperative high neutrophil-to-lymphocyte ratio (NLR, >2.42), high platelet count (>2.36 × 109/L), and low red blood cell (RBC) count (≤4.59 × 1012/L) were independent prognostic factors for poorer OS (p = 0.030, p = 0.030, and p = 0.004, respectively). Moreover, a high NLR was an independent prognostic factor for shorter PFS (p = 0.010). We also found that, like NLR, preoperative high derived NLR (dNLR, >1.89) was of poor prognostic value for both PFS (p = 0.002) and OS (p = 0.033). A significant correlation was observed between NLR and dNLR (r = 0.88, p < 0.001), which had a similar prognostic power for OS (NLR: AUC = 0.58; 95% CI: [0.48; 0.68]; dNLR: AUC = 0.62; 95% CI: [0.51; 0.72]). Two scores, one based on preoperative platelet and RBC counts plus NLR and the other on preoperative platelet and RBC counts plus dNLR, were found to be independent prognostic factors for PFS (p = 0.006 and p = 0.002, respectively) and OS (p < 0.001 for both scores). Conclusion: Cheap, routinely ordered, preoperative assessments of blood markers, such as NLR, dNLR, RBC, and platelet counts, can predict the survival outcomes of patients with IDH-wildtype GB treated with the standard therapy.
