Objective. This study was aimed at exploring the diagnostic and prognostic value of long noncoding RNA LINC01554 (LINC01554) in epithelial ovarian cancer (EOC) patients. Patients and Methods. The expressions of LINC01554 in 161 EOC patients were analyzed using RT-PCR. The area under the ROC curve (AUC) was used to estimate the effectiveness of LINC01554 for prediction. The chi-square test was performed to explore the association between LINC01554 expressions and clinical characteristics in EOC patients. Kaplan-Meier assays were conducted for the examination of the influence of LINC01554 expression on the overall survival of EOC patients. Multivariate analyses were carried out to further determine prognostic values of LINC01554 expression in EOC patients. Results. LINC01554 expressions were strongly downregulated in EOC specimens compared with matched nontumor specimens ( p < 0.01 ). Importantly, LINC01554 provided a high diagnostic performance for the detection of EOC specimens ( AUC = 0.7827 ; p < 0.001 ). Low expression of LINC01554 was distinctly associated with the FIGO stage ( p = 0.034 ) and distant metastasis ( p = 0.007 ). The assays of survival data (five years) revealed that the 5-year overall survival of the low LINC01554 expression group was distinctly shorter than that of the high LINC01554 expression group ( p = 0.0017 ). Finally, in the multivariate Cox model, LINC01554 expression ( RR = 2.863 , 95% CI: 1.185-4.421, p = 0.014 ) was demonstrated to be an independent prognostic factor for overall survival of EOC patients. Conclusions. Our findings suggested that LINC01554 is an important EOC-related lncRNA, providing a potential diagnostic, prognostic biomarker and therapeutic target for EOC patients.

Tumor-stroma ratio (TSR) has recently been identified as a promising prognostic parameter for several solid tumors. This study aimed to evaluate the prognostic role of TSR in epithelial ovarian cancer (EOC) and 838 EOC patients were enrolled in this study. TSR was estimated on hematoxylin-and-eosin-stained tissue sections from the most invasive part of the primary tumor. Patients were classified as stroma-rich or stroma-poor according to the proportion of stroma ≥50% or <50%. Chi-square test analysis revealed that TSR were significantly associated with FIGO stage, LN status, and recurrence or not (all of themP<0.001). The higher stroma-rich proportions were found in EOC patients with advanced stage (36.13% versus 19.75%), LN metastasis (51.93% versus 27.25%), and recurrence (34.27% versus 6.82%). Stroma-rich EOC patients had obvious shorter median time of progression-free survival (29 versus 39 months) and overall survival (50 versus 58 months), respectively. TSR was an independent prognostic factor for the evaluation of PFS in EOC. Stroma-rich tumors had worse prognosis and higher risk of relapse compared with those in stroma-poor tumors in EOC patients. Considered easy to determine for routine pathological examination, TSR may serve as a new prognostic histological parameter in EOC.

ObjectiveThe revised version of the International Federation of Gynaecology and Obstetrics (FIGO) staging system (2014) for epithelial ovarian cancer includes a number of changes. One of these is the division of stage IV into 2 subgroups. Data on the prognostic and predictive significance of this classification are scarce. The effect of neoadjuvant chemotherapy (NACT) versus primary debulking surgery (PDS) in relation to the subclassification of FIGO stage IV is also unknown.MethodsWe used data of the EORTC 55971 trial, in which 670 patients with previous stage IIIC or IV epithelial ovarian cancer were randomly assigned to PDS or NACT; 160 patients had previous stage IV. Information on previous FIGO staging and presence of pleural effusion with positive cytology were used to classify tumors as either stage IVA or IVB. We tested the association between stage IVA/IVB and survival to evaluate the prognostic value and interactions between stage, treatment, and survival to evaluate the predictive performance.ResultsAmong the 160 participants with previous stage IV disease, 103 (64%) were categorized as stage IVA and 57 (36%) as stage IVB tumors. Median overall survival was 24 months in FIGO stage IVA and 31 months in stage IVB patients (P = 0.044). Stage IVB patients treated with NACT had 9 months longer median overall survival compared with IVB patients undergoing PDS (P = 0.025), whereas in IVA patients, no significant difference was observed (24 vs 26 months, P = 0.48).ConclusionsThe reclassification of FIGO stage IV into stage IVA or IVB was not prognostic as expected. Compared with stage IVA patients, stage IVB patients have a better overall survival and may benefit more from NACT.

BackgroundThe addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery improves recurrence-free and overall survival in patients with FIGO stage III ovarian cancer who are ineligible for primary cytoreductive surgery. The effect of HIPEC remains undetermined in patients who are candidates for primary cytoreductive surgery.Primary objectiveThe primary objective is to evaluate the effect of HIPEC on overall survival in patients with FIGO stage III epithelial ovarian cancer who are treated with primary cytoreductive surgery resulting in no residual disease, or residual disease up to 2.5 mm in maximum dimension.Study hypothesisWe hypothesize that the addition of HIPEC to primary cytoreductive surgery improves overall survival in patients with primary FIGO stage III epithelial ovarian cancer.Trial designThis international, randomized, open-label, phase III trial will enroll 538 patients with newly diagnosed FIGO stage III epithelial ovarian cancer. Following complete or near-complete (residual disease ≤2.5 mm) primary cytoreduction, patients are randomly allocated (1:1) to receive HIPEC or no HIPEC. All patients will receive six courses of platinum-paclitaxel chemotherapy, and maintenance PARP-inhibitor or bevacizumab according to current guidelines.Major eligibility criteriaPatients with FIGO stage III primary epithelial ovarian, fallopian tube, or primary peritoneal cancer are eligible after complete or near-complete primary cytoreductive surgery. Patients with resectable umbilical, spleen, or local bowel lesions may be included. Enlarged extra-abdominal lymph nodes should be negative on FDG-PET or fine-needle aspiration/biopsy.Primary endpointThe primary endpoint is overall survival.Sample sizeTo detect a HR of 0.67 in favor of HIPEC, 200 overall survival events are required. With an expected accrual period of 60 months and 12 months additional follow-up, 538 patients need to be randomized.Estimated dates for completing accrual and presenting resultsThe OVHIPEC-2 trial started in January 2020 and primary analyses are anticipated in 2026.Trial registrationClinicalTrials.gov:NCT03772028
