Validation of tumour-free distance as novel prognostic marker in early-stage cervical cancer: a retrospective, single-centre, cohort study.

ABSTRACT:

Background

The aim of the present study was to assess the prognostic value of tumour-free distance (TFD), defined as the minimum distance of uninvolved stroma between the tumour and peri-cervical stromal ring, in early-stage cervical cancer.

Methods

Patients with pathologic FIGO 2009 stage IA1-IIA2 cervical cancer, treated by primary radical surgical treatment between 01/2000 and 11/2019, were retrospectively included. Adjuvant treatment was administered according to the presence of previously established pathologic risk factors. TFD was measured histologically on the hysterectomy specimen. Pre-operative TFD measured at MRI-scan from a cohort of patients was reviewed and compared with pathology TFD.

Results

395 patients were included in the study. 93 (23.5%) patients had TFD ≤ 3.0 mm and 302 (76.5%) had TFD > 3.0 mm. TFD ≤ 3.0 mm together with lymph vascular space involvement represented the strongest predictor for lymph node metastasis at multivariate analysis. TFD ≤ 3.0 mm was associated with worse 5-year disease-free survival (DFS) and overall survival (OS), compared with TFD > 3.0 mm (p = 0.022 and p = 0.008, respectively). DFS difference was more evident in the subgroup of patients with low-risk factors who did not receive adjuvant treatment (p = 0.002). Cohen's kappa demonstrated an agreement between TFD measured at pre-operative MRI-scan and histology of 0.654.

Conclusions

Pathologic TFD ≤ 3.0 mm represents a poor prognostic factor significantly associated with lymph node metastasis and it may be considered a novel marker to select candidates for adjuvant treatment. The possibility to obtain this parameter by radiological imaging makes it a potential easy-measurable pre-operative marker to predict the presence of high-risk pathologic factors in early-stage cervical cancer.

Project description:BackgroundCervical cerclage has been proposed as an effective treatment for cervical insufficiency, but there has been controversy regarding the surgical options of cervical cerclage in singleton and twin pregnancies. This study aimed to compare the pregnancy outcomes between transvaginal cervical cerclage (TVC) and laparoscopic abdominal cervical cerclage (LAC) in patients with cervical insufficiency. We also aimed to evaluate the efficacy and safety, and provide more evidence to support the application of cervical cerclage in twin pregnancies.MethodsA retrospective study was carried out from January 2015 to December 2021. The primary outcomes were the incidence of spontaneous preterm birth (sPTB) < 24 weeks, < 28, < 32, < 34 weeks, and < 37weeks, gestational age at delivery, and the incidence of admission for threatened abortion or preterm birth after cervical cerclage. The secondary outcomes included admission to the Neonatal Intensive Care Unit, adverse neonatal outcomes and neonatal death. We also analysed the pregnancy outcomes of twin pregnancies after cervical cerclage.ResultsA total of 289 patients were identified as eligible for inclusion. The LAC group (n = 56) had a very low incidence of sPTB ˂ 34 weeks, and it was associated with a significant decrease in sPTB < 28 weeks, ˂32 weeks, ˂34 and < 37 weeks, and admission to the hospital during pregnancy for threatened abortion or preterm birth after cervical cerclage (0 vs.27%; 1.8% vs. 40.3%; 7.1% vs. 46.8%; 14% vs. 63.5%, 8.9% vs. 62.2%, respectively; P < 0.001), and high in gestational age at delivery compared with the TVC group (n = 233) (38.3 weeks vs.34.4 weeks,P < 0.001). Neonatal outcomes in the LAC group were significantly better than those in the TVC group. The mean gestational age at delivery was 34.3 ± 1.8 weeks, with a total foetal survival rate of 100% without serious neonatal complications in twin pregnancies with LAC.ConclusionIn patients with cervical insufficiency, LAC appears to have better pregnancy outcomes than TVC. For some patients, LAC is a recommended option and may be selected as the first choice. Even in twin pregnancies, cervical cerclage can improve pregnancy outcomes with a longer latency period, especially in the LAC group.
