Purpose: Malignant ovarian germ cell tumors are rare and knowledge about prognostic parameters currently is limited. This study was undertaken to evaluate long-term outcome of patients with malignant ovarian germ cell tumors (MOGCTs) after chemotherapy and to assess prognostic parameters.
Patients And Methods: A total of 113 patients with stage IC to IV MOGCTs were included into this retrospective study. Patients were treated at two large regional cancer centers between 1977 and 2003.
Results: Ten-year recurrence-free and overall survival rates were 82% and 81%, respectively. A total of 20 patients experienced relapse, all within the first 8 years. Outcome after relapse was poor, with only 10% of patients achieving long-term survival. Univariate and multivariate analyses demonstrated that initial stage of disease (relative risk [RR], 5.96; 95% CI, 3.47 to 10.22; P = .03) and elevation of serum markers beta-human chorionic gonadotropin and alpha-fetoprotein (RR, 3.90; 95% CI, 1.40 to 10.9; P = .009) were significant predictors of overall survival, whereas age at diagnosis was of no prognostic value.
Conclusion: This is the first study to identify stage and tumor markers as prognostic parameters for patients with MOGCTs. This might help to select patients for risk-adapted treatment. There is need for improvement of therapeutic strategies after relapse.

Introduction: Ovarian cancer is one of the most lethal gynecological cancers. Despite diagnosis and treatment advances, survival rates have not increased over the past 32 years. This study estimated and reported the global burden of ovarian cancer during the past 32 years to inform preventative and control strategies.

Objective: To evaluate the impact of the different types of neoplasms and lineages on Sjögren syndrome (SjS) patient mortality.
Methods: Medical records review study based on the Spanish Hospital Discharge Database and the International Classification of Diseases, Tenth Revision, Clinical Modification coding list. The neoplasm-related deaths in SjS patients with the general population during the period 2016-2019 were compared.

The ovarian oncobiome is subject to increasing scientific focus, but a potential link between bacterial dysbiosis and ovarian carcinogenesis remains controversial. Our primary aim was to characterize the bacterial microbiota in epithelial ovarian cancer samples. Secondarily, we aimed to compare results from the bacterial microbiota in formalin-fixed, paraffin-embedded ovarian tissue samples from 194 patients with epithelial ovarian cancer, fallopian tube tissue samples from 16 patients with serous tubal intraepithelial carcinomas and in benign fallopian tube tissue samples from 25 patients.

Cancer stem cells play an important role in tumor progression and chemotherapy resistance. Leucine-rich G repeat-containing protein-coupled receptor 5 (LGR5) has been identified as a cancer stem cell marker in several cancer types. LGR5 is involved in cancer development and progression via several pathways including WNT/β-catenin signaling pathway.
