Abstract
Introduction In early-stage epithelial ovarian cancer (EOC), how to perform lymphadenectomy to avoid stage migration and achieve reliable targeted excision has not been explored in depth. This study comprehensively considered the stage migration and survival to determine appropriate numbers of examined lymph node (ELN) for early-stage EOC and high-grade serous ovarian cancer (HGSOC). Methods From the Surveillance, Epidemiology, and End Results database, we obtained 10372 EOC cases with stage T1M0 and ELN ≥ 2, including 2849 HGSOC cases. Generalized linear models with multivariable adjustment were used to analyze associations between ELN numbers and lymph node stage migration, survival and positive lymph node (PLN). LOESS regression characterized dynamic trends of above associations followed by Chow test to determine structural breakpoints of ELN numbers. Survival curves were plotted using Kaplan-Meier method. Results More ELNs were associated with more node-positive diseases, more PLNs and better prognosis. ELN structural breakpoints were different in subgroups of early-stage EOC, which for node stage migration or PLN were more than those for improving outcomes. The meaning of ELN structural breakpoint varied with its location and the morphology of LOESS curve. To avoid stage migration, the optimal ELN for early-stage EOC was 29 and the minimal ELN for HGSOC was 24. For better survival, appropriate ELN number were 13 and 8 respectively. More ELNs explained better prognosis only at a certain range. Discussion Neither too many nor too few numbers of ELN were ideal for early-stage EOC and HGSOC. Excision with appropriate numbers of lymph node draining the affected ovary may be more reasonable than traditional sentinel lymph node resection and systematic lymphadenectomy.

Trefoil factor family proteins as potential diagnostic markers for mucinous invasive ovarian carcinoma. Front Oncol 2023; 12:1112152. [PMID: 36818673 PMCID: PMC9932968 DOI: 10.3389/fonc.2022.1112152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 12/28/2022] [Indexed: 02/05/2023] Open
Abstract
Introduction Ovarian cancer (OC) is the leading cause of gynecological cancer-related death. Of the main OC histologic subtypes, invasive mucinous carcinomas (MC) account for only 3% of OC cases and are frequently associated with favorable prognosis. Nevertheless, MCs differ greatly from the other OC histotypes in clinical, pathological, and biological behavior. However, the origin and molecular pathogenesis of MC are not yet fully understood. Therefore, identification of novel diagnostic markers could potentially facilitate early diagnosis of OC, particularly the MC histotype, thereby leading to the development of histotype-specific treatment regimens and improved survival rates. Methods In the present study, Trefoil factor gene family members (TFF1, TFF2 and TFF3) were identified as MC histotype-specific biomarkers using RNA sequencing (RNA-seq) data for 95 stage I-II OCs. The diagnostic value of TFF1, TFF2 and TFF3 was then evaluated by immunohistochemistry on 206 stage I-II OCs stratified by histotype (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], clear cell carcinoma [CCC], and MC). Results We showed significantly elevated intracytoplasmic protein expression levels for TFF1, TFF2 and TFF3 in MC samples, thereby revealing an association between expression of Trefoil factor gene family members and the MC histotype. Taken together, these findings suggest that the TFF proteins may play a pivotal role in tumor initiation and progression for the MC histotype. Conclusion Taken together, these findings suggest that the TFF proteins may play a pivotal role in tumor initiation and progression for the MC histotype. Moreover, these novel histotype-specific diagnostic biomarkers may not only improve patient stratification of early-stage ovarian carcinomas but may also be candidates for the development of molecular targeted therapies.

Abstract
ObjectiveTo evaluate the therapeutic role of pelvic and aortic lymphadenectomy in patients with epithelial ovarian cancer (EOC) and positive nodes (stages IIIC and IV).MethodsRetrospective chart review. Data from all consecutive patients with EOC and positive retroperitoneal lymph nodes (stage IIIC and IV) in Mayo Clinic from 1996 to 2000 were included. To evaluate the impact of nodal metastases, the extent of lymphadenectomy was compared according to the number of nodes removed and positive nodes resected. Multivariable Cox regression and Kaplan-Meier survival curves were used for analysis.ResultsThe median number of nodes removed was 31 (pelvic, 21.5, and aortic, 10), and the median number of positive nodes was 5. The 5-year overall survival was 44.8%. On multivariate analysis, only the extent of peritoneal metastases before surgery was a significant factor for survival (P = 0.001 for stage IIIC and P = 0.004 for stage IV). Analysis of 83 patients with advanced peritoneal disease more than 2 cm demonstrated before debulking, removal of more than 40 lymph nodes was a significant prognostic factor for overall survival (hazard ratio, 0.52; P = 0.032; 95% confidence interval, 0.29–0.35). In 29 patients with advanced peritoneal disease and no residual disease after debulking, removal of more than 10 positive was a factor for survival.ConclusionsThere was a survival benefit in patients with EOC with advanced peritoneal disease more than 2 cm before debulking when more than 40 lymph nodes were removed. There was an additional survival benefit in those patients with no residual disease after debulking when more than 10 positive nodes were removed.
