Is advanced bipolar v anced bipolar vessel sealing de essel sealing device really eff eally effective in decreasing the pelvic lymphocele ratio in open surgery for endometrial cancer?

BACKGROUND: We aim to show pelvic lymphocele (PL) rates in patients who were operated for endometrial cancer (EC) and underwent systematic paraaortic bilateral pelvic lymph node dissection (PABPLND) with advanced bipolar vessel sealing device (ABVSD). METHODS: The medical files of all patients who underwent open surgery for EC between January 2017 and December 2021 were retrospectively analyzed. One hundred three patients who operated with the diagnosis of high-intermediate and high-risk endometrial cancer were included. Systematic PABPLND was performed with total abdominal hysterectomy with or without bilateral salpingo-oophorectomy during surgery to all patients. All operations were performed by same three surgeons who were expert in their field. While the lymph packages were removed during surgical dissection, the distal afferent and proximal efferent lymphatic channels were sealed with LigaSure™ blunt tip sealer/divider (Medtronic, Covidien, USA). The patients were scanned with computed tomography (CT) between 8 and 12 weeks postoperatively. Lymphocele diagnosis was confirmed by radiologists and largest diameter was recorded. Clinical-pathological findings of all patients were recorded. RESULTS: Mean age and body mass index (BMI) of all participants were 58.6 ±10.2 years and 28.1± 5.6 kg/m2 . The most histopathological findings were endometrioid type (84.5%) and grade 2 (44.2%) ECs. The pelvic lymphocele (PL) was detected with CT in 24 of 103 patients at 8 to 12 weeks postoperatively. Only two PL patients were symptomatic. The first patient had symptoms of pelvic fullness and compression while the second patient had infected image. PL was located to right pelvic area in first case while the second was located on the vaginal cuff. DISCUSSION: The dissection and sealing of major lymph vessels were achieved during the removal of all lymph packages with LigaSure™ blunt tip laparoscopic sealer/divider. The use of advanced bipolar systems can reduce the formation of PL in lymph node dissection in endometrial cancer.

The Effect of Prognostic Factors and Adjuvant Radiotherapy on Survival in Patients with High-Grade Early-Stage Endometrial Cancer: A Retrospective Clinical Study.

BACKGROUND This retrospective clinical study aimed to investigate the effect of prognostic factors and adjuvant radiotherapy in patients with high-grade early-stage endometrial cancer on overall survival (OS) and disease-free survival (DFS). MATERIAL AND METHODS The medical records of patients diagnosed with high-grade, early stage (I or II) endometrial adenocarcinoma who had received adjuvant radiotherapy after surgery were reviewed. RESULTS Seventy-nine patients included 39 patients (49.4%) with stage II endometrial cancer, 25 patients (31.6%) with histologic grade 3 tumors, and 47 patients (59.5%) with endometrial cancer showing lymphovascular space invasion (LVSI). There were 45 patients (57.0%) who received external pelvic radiotherapy with an average dose of 46.0 Gy (range, 11.2-50.4 Gy), and 34 patients (43.0%) received vaginal brachytherapy (VBT) with an average dose of 21.5 Gy (range, 10-36 Gy). Multivariate analysis showed that tumor stage (HR, 4.066; 95% CI, 1.227-13.467; p=0.022) and histologic grade (HR, 16.652; 95% CI, 4.430-62.589; p<0.001) were independent predictors for OS. Increased serum CA-125 levels (HR, 1.136; 95% CI, 0.995-1.653; p=0.047) and histologic grade (HR, 3.236; 95% CI, 1.107-15.156; p=0.015) were independent predictors for DFS. Adjuvant radiotherapy was not found to be significantly associated with improved OS (HR, 1.259; 95% CI, 0.518-3.058; p=0.612) or DFS (HR, 1.056; 95% CI, 0.994-1.123; p=0.078). CONCLUSIONS This retrospective study showed that in high-grade early-stage endometrial cancer treated with postoperative adjuvant radiotherapy, independent predictors for OS were tumor stage and grade. Adjuvant radiotherapy was not associated with improved OS or DFS.
