Purpose Surgery consists the main treatment of endometrial cancer; however, decision of lypmhadenectomy is controversial. Intra-operative frozen section (FS) is commonly used in guiding surgical staging; nevertheless, there are different reports regarding its adequacy and reliability. Aim of this study is to assess accuracy of FS in predicting paraffin section (PS) results in patients with endometrium cancer. Methods Data of 223 cases, who were operated for endometrial cancer at a tertiary hospital in 2012-2019, were analyzed retrospectively. Histological type, grade, tumor diameter, depth of myometrial invasion, and cervical and adnexal involvement in frozen and paraffin section were evaluated. Positive and negative predictive values and accuracy of frozen results in predicting paraffin results for each parameter was assessed. Statistical significance was taken as 0.05 in all tests. Results Accuracy of FS in predicting PS results were 76.23% for histology, 75.45% for grade, 85.31% for depth of myometrial invasion, and 95.45% for tumor diameter. Surgery, based on FS results, caused undertreatment in 4 patients, while metastatic lymph node ratios were found in only 35.3-50.0% of cases who had high risk parameters at FS. Conclusion Our FS results have reasonable accuracy rates in predicting PS results, in comparison with the previous literature. However, even if the high risk parameters detected in FS predict PS accurately, absence of lymph node involvement in all cases with high risk parameters indicates that FS-based triage cannot prevent unnecessary lymphadenectomies.
Laparoscopic para-aortic lymphadenectomy: Technique and surgical outcomes
(2021) Durda, Gulsen Dogan; Alemdaroglu, Songul; Baran, Safak Yilmaz; Yaginc, Didem Alkas; Simsek, Seda Yuksel; Celik, Husnu; 0000-0003-4335-6659; 0000-0001-5874-7324; 0000-0001-8309-3537; 0000-0003-1185-9227; 32961327; AAI-8400-2021; AAK-2461-2021; AAL-1923-2021
Objective: Pelvic and para-aortic lymph node dissection is an important part of staging surgery. Aim of this study is to evaluate perioperative outcomes of patients, who underwent laparoscopic para-aortic lymphadenectomy for gynecological cancer in a single center over a period of 7 years, based on body mass index (BMI), and to present the surgical technique in steps. Methods: Data of patients who underwent para-aortic lymphadenectomy at gynecological oncology department of a tertiary center in between March 2013 and July 2020 were analyzed retrospectively. Patients were evaluated in two groups according to their BMI (< 30 kg/m(2) as non-obese and >= 30 kg/m(2) as obese groups). Surgical technique is described in steps. Perioperative outcomes of the two groups were evaluated. Results: A total of 230 patients were included in the study. BMI was >= 30 at 58.46 % of the patients. Perioperative features were not significantly affected by the patient's BMI with the presented surgical technique, however, collected para-aortic lymph node numbers were higher in the group with BMI <30, though sufficient number of lymph nodes were achieved in both groups. Conclusion: Although some technical difficulties may be encountered, laparoscopic para-aortic lymphadenectomy is feasable in gynecologic oncological surgery independent of BMI. However, surgical experience is important. (C) 2020 Elsevier Masson SAS. All rights reserved.
