Staging In Early Stage Endometrial Cancer Research Articles

Comparing Surgical and Oncological Outcomes between Indocyanine Green (ICG) Sentinel Lymph Node Mapping with Routine Lymphadenectomy in the Surgical Staging of Early-Stage Endometrioid Endometrial Cancer.

A retrospective single-centre cohort study of patients with early-stage endometrioid endometrial cancer undergoing staging surgery (total hysterectomy, bilateral salpingo-oophorectomy with/without pelvic lymph node, and/or para-aortic lymph node dissection (PLND)) with either SLN mapping or routine lymphadenectomy between July 2017 and December 2018. 203 cases with clinical and radiological International Federation of Gynaecology and Obstetrics (FIGO) stage I endometrioid endometrial cancer were included, out of which 109 cases underwent SLN mapping and 94 cases complete lymphadenectomy. Compared to the PLND group, the SLN group had shorter operative time (129 vs. 162 minutes), less blood loss (100 vs. 300 ml), and decreased length of postoperative hospital stay (3 vs. 4 days) (p < 0.001). The lymph node metastases detection rate was 4.6% and 7.4% for the SLN and PLND groups, respectively (p = 0.389). With a median follow-up of 14 months for the SLN and 15 months for the PLND group, the disease-free (DFS) and overall survival (OS) were comparable for both at 13 months (p = 0.538 and p = 0.333, respectively). SLN mapping has been shown to be an acceptable alternative to routine lymphadenectomy in the surgical staging of early-stage endometrial cancer in our centre, with a comparable lymph node metastases detection rate, DFS and OS, and reduction in operative morbidity. Our results with SLN mapping reproduce comparable outcomes to those reported in the literature.

Utility of indocyanine green as a single tracer for sentinel node biopsy in endometrial cancer.

Our study aims to investigate the safety and effectiveness of sentinel lymph node biopsy using indocyanine green (ICG) for the surgical staging of early-stage endometrial cancer in comparison to technetium-99 m use. We conducted an observational retrospective study with patients diagnosed of endometrial cancer and FIGO stages I-II. All participants were injected technetium-99m the day prior to the surgery and underwent lymphoscintigraphy along with single-photon emission computed tomography. In addition, all patients were administered intraoperatively ICG injection to detect sentinel lymph node biopsy. The surgical staging was then completed according to the European Society for Medical Oncology preoperative risk category. Data obtained from the analysis of technetium-99m detection was compared to ICG detection. A total of 53 women with endometrial cancer were included in the study, 49 (92.5%) of them showed drainage preoperatively in the single-photon emission computed tomography and/or lymphoscintigraphy. The intraoperative bilateral detection rate for technetium-99 m was 26 (49.1%) patients compared to 40 (75.5%) patients with ICG (p= 0.013). We observed a 42.5% increase in the mean number of lymph nodes retrieved by ICG compared to technetium-99m (2.85 vs 2,0 nodes; p= 0.002). We intraoperatively identified 164 lymph nodes, 104 (63.4%) located in both obturator areas and external iliac vessels. The use of ICG for the performance of sentinel node biopsy in patients with endometrial cancer seems safe and could be superior to technetium-99 m, since it offers a higher bilateral detection rate and nodal retrieval, resulting in the possibility to perform safely less full staging lymphadenectomies.

Identification of microRNA expression profile related to lymph node status in women with early-stage grade 1–2 endometrial cancer

Conventional methods used for histologic classification and grading of endometrial cancer (EC) are not sufficient to predict lymph node metastases. microRNA signatures have recently been related to EC pathologic characteristics or prognosis. The aim of this study was to evaluate whether microRNA profiles of grade 1–2 endometrioid adenocarcinomas can be related to nodal status and used as a tool to adapt surgical staging in early-stage EC. microRNA expression was assessed in nine formalin-fixed paraffin-embedded (FFPE) EC primary tumors with positive lymph node and in 27 FFPE EC primary tumors with negative lymph node, matched for grade, stage, and lymphovascular space involvement status. A microarray analysis showed that there was more than a twofold significant difference in the expression of 12 microRNAs between the two groups. A quantitative reverse transcriptase–PCR assay was used to confirm these results: the expression levels of five microRNAs (microRNA-34c-5p, -375, -184, -34c-3p, and -34b-5p) were significantly lower in the EC primary tumor with positive lymph node compared with those with negative lymph node. A minimal P-value approach revealed that women with a microRNA-375-fold change <0.30 were more likely to have positive lymph node (n=8; 53.3%) compared with those with a microRNA-375-fold change >0.30 (n=1; 4.8%), P=0.001. Furthermore, women with a microRNA 184-fold change <0.30 were more likely to have positive lymph node (n=6; 60.0%) compared with those with a microRNA 184-fold change >0.30 (n=3; 11.5%), P=0.006. This is the first study investigating the relative expression of mature microRNA genes in early-stage grade 1–2 EC primary tumors according to the nodal status. This microRNA expression profile provides a potential basis for further study of the microRNA function in EC and could be used as a diagnostic tool for nodal status.

Analysis of survival after laparoscopic-assisted vaginal hysterectomy compared with the conventional abdominal approach for early-stage endometrial carcinoma: A review of the literature

Study objective To assess potential differences in perioperative features and survival between laparoscopic-assisted vaginal hysterectomy and conventional transabdominal hysterectomy in stage I endometrial cancer. Design Retrospective, nonrandomized clinical study (Canadian Task Force classification II-2). Setting Acute-care, teaching hospital. Patients A total of 370 patients undergoing hysterectomy and bilateral salpingo-oophorectomy with surgical staging for primary treatment for clinical stage I endometrial cancer from January 1995 through June 2001. Intervention Clinical outcomes and survival in patients treated with laparoscopic-assisted vaginal hysterectomy (n = 55) and hysterectomy using the conventional abdominal approach (n = 315) were compared. Measurements and main results Baseline characteristics and histopathologic variables were similar in both groups. A total of 91.4% of patients underwent pelvic lymphadenectomy and 49.7% paraaortic lymphadenectomy. The median follow-up was 38.1 months. Blood loss, blood transfusions required, and length of stay were significantly lower in the laparoscopic group, but surgical time was significantly longer. The mean number of pelvic and aortic nodes recovered was higher in the laparoscopic group (p <.001). Differences in overall and recurrence-free survival rates were not observed. Conclusion Surgical staging of early-stage endometrial cancer by laparoscopic-assisted vaginal hysterectomy is feasible, with lower perioperative morbidity and shorter hospital stay compared with transabdominal hysterectomy. Prognosis and survival were not affected by the laparoscopic vaginal approach to hysterectomy.
