Objective: Since there have been few large series studies to date, we investigated the relationship between Trousseau's syndrome associated with cerebral infarction and its clinical associations with ovarian cancer. Methods: In this study, we investigated the association between cerebral infarction onset and ovarian cancer. Eight-hundred twenty-seven consecutive ovarian cancer patients from 4 affiliated academic institutions were included in the study over a 12 years period. All patients were histopathologically diagnosed as epithelial ovarian cancer and were analyzed retrospectively. Results: The 27 patients (3.2%) presented with cerebral infarction during the study period, 14 patients onset prior to treatment (1.7%), and 13 patients onset after start of initial treatment (1.5%). Univariate analysis and multivariate analysis was performed for onset of Trousseau's syndrome and various clinical and pathological parameters. There was no statistical significance between the occurrence of Trousseau's syndrome with age or International Federation of Gynecology and Obstetrics (FIGO) stage; however, univariate analysis and multivariate analysis demonstrated a statistically significant association between clear cell carcinoma (CCC) and non-CCC histology. Conclusion: Thus, our results demonstrate that Trousseau's syndrome with cerebral infarction occurred with greater incidence among CCC cases compared to non-CCC cases.

Objective: The aim of the study is to investigate recurrence of stage I epithelial ovarian cancer. Methods: Six hundred two patients diagnosed with stage I epithelial ovarian cancer at 4 hospitals between 2000 and 2013 were retrospectively analyzed. Age, surgical procedure, substage, histologic type, adjuvant chemotherapy, recurrence, initial recurrence site (peritoneal dissemination [P], hematogenous recurrence [H], lymphogenous recurrence [L], and others [O]), and frequency of recurrence at each site were investigated retrospectively. Results: Median age was 54 years and median follow-up was 60 months. The stage was IA in 180 cases (30%), IB in 8 (1%), IC1 in 247 (41%), IC2 in 63 (10%), and IC3 in 104 (17%). Systematic lymph node dissection including both pelvic and para-aortic lymph nodes was performed in 224 patients (37%), and 412 patients (68%) received adjuvant chemotherapy. Recurrence occurred in 70 patients (11.6%). The median time to recurrence was 18 months, and the stage was IA in 13 (19%), IB in 1 (1%), IC1 in 24 (34%), IC2 in 9 (13%), and IC3 in 23 (33%) cases. The numbers of recurrence at the P, H, L, and O sites, including overlapping cases, were 49 (70%), 18 (26%), 9 (13%), and 6 (9%), respectively, and recurrence by peritoneal dissemination in the pelvis occurred in 43 cases (61%). Conclusion: Recurrence of stage I epithelial ovarian cancer by peritoneal dissemination was frequent, especially in the pelvis. There is a need to elucidate the pathogenesis of peritoneal recurrence and to prepare a treatment strategy to prevent pelvic peritoneal recurrence.

Objective: Direct oral anticoagulants (DOACs) are increasingly being used for the treatment of cancer-associated venous thromboembolism (CAT). However, there is limited evidence of the efficacy of DOACs for the treatment of gynecological CAT. Thus, this study aimed to investigate the efficacy and safety of edoxaban for the treatment of gynecological CAT using Japanese real-world data. Methods: We reviewed the medical records of patients with 371 gynecological cancer who received edoxaban or vitamin K antagonist (VKA) between January 2011 and December 2018. Results: Altogether, 211 and 160 patients were treated with edoxaban and VKA, respectively. Fourteen patients (6.8%) in the edoxaban group and 22 (13.8%) in the VKA group showed recurrence of venous thromboembolism (VTE). Cumulative VTE recurrence was not significantly different between the 2 groups (p=0.340). Adverse events occurred in 15 (7.1%) and 11 (6.9%) patients in the edoxaban and VKA groups, respectively (p=0.697). Subgroup analysis of the edoxaban and VKA groups according to different tumor types, including ovarian, endometrial, and cervical cancer, showed equivalent outcomes in terms of VTE recurrence and adverse events. Patients without pulmonary embolism (PE) were mostly omitted from initial unfractionated heparin (UFH) therapy prior to administration of edoxaban. However, this did not increase the recurrence of VTE. Conclusion: This study confirmed that edoxaban is effective and safe for the treatment of gynecological CAT. This finding was consistent for different types of gynecological cancer. Additionally, initial UFH therapy prior to the administration of edoxaban may be unnecessary for patients without PE.
