RESUMO
A corded and hyalinized pattern has been described in endometrial endometrioid carcinoma. Herein, we describe a clinicopathological and molecular analysis of the first reported case of endometrial serous carcinoma with a corded and hyalinized pattern.A 64-year-old woman underwent hysterectomy and bilateral salpingo-oophorectomy due to a 5.5 cm endometrial lesion. Histologically, the tumor was composed of a minor (20%) serous carcinoma component and a predominant corded component embedded in a hyaline-to-myxoid matrix. This component showed diffuse and strong p53 and p16 expression, heterogeneous positivity for epithelial markers and WT1, focal positivity for estrogen and progesterone receptors, retained MMR, SMARCA4/BRG1, and SMARCB1/INI1 expression, and negativity for smooth muscle, germ cell, sex cord, neuroendocrine, endothelial, and melanocytic markers and GATA3. Next-generation sequencing showed a mutation of uncertain significance in APC and no mutations in MLH1, MSH2, MSH6, PMS2, MUTYH, POLE, POLD1, EPCAM, or CTNNB1. The patient had a recurrence on the vaginal stump after 15 months.In conclusion, endometrial serous carcinoma can show a corded and hyalinized pattern, which may represent a diagnostic challenge.

INTRODUCTION: Sentinel lymph node (SLN) biopsy is part of surgical treatment of apparent early-stage cervical cancer. SLN is routinely analyzed by ultrastaging and immunohistochemistry. The aim of this study was to assess the survival of patients undergoing SLN analyzed by one-step nucleic acid amplification (OSNA) compared with ultrastaging. METHODS: Single-center, retrospective, cohort study. Patients undergoing primary surgery and SLN mapping ( ±pelvic lymphadenectomy) for apparent early-stage cervical cancer between May 2017 and January 2021 were included. SLN was analyzed exclusively with OSNA or with ultrastaging. Patients with bilateral SLN mapping failure, with SLN analyzed alternatively/serially with OSNA and ultrastaging, and undergoing neo-adjuvant therapy were excluded. Baseline clinic-pathological differences between the two groups were balanced with propensity-match analysis. RESULTS: One-hundred and fifty-seven patients were included, 50 (31.8%) in the OSNA group and 107 (68.2%) in the ultrastaging group. Median follow up time was 41 months (95%CI:37.9-42.2). 5-year DFS in patients undergoing OSNA versus ultrastaging was 87.0% versus 91.0% (p = 0.809) and 5-year overall survival was 97.9% versus 98.6% (p = 0.631), respectively. No difference in the incidence of lymph node recurrence between the two groups was noted (OSNA 20.0% versus ultrastaging 18.2%, p = 0.931). In the group of negative SLN, no 5-year DFS difference was noted between the two groups (p = 0.692). No 5-year DFS and OS difference was noted after propensity-match analysis (87.6% versus 87.0%, p = 0.726 and 97.4% versus 97.9%, p = 0.998, respectively). CONCLUSION: The use of OSNA as method to exclusively process SLN in cervical cancer was not associated with worse DFS compared to ultrastaging. Incidence of lymph node recurrence in the two groups was not different.

OBJECTIVE: To evaluate the safety and feasibility of the new surgical robot HUGO robotic assisted surgery (RAS) in a series of gynecologic surgical procedures. METHODS: Between March and October 2022, 138 patients treated at Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy were enrolled in the study. All patients suitable for a minimally-invasive approach were prospectively included and divided into two groups: Group 1 (78 patients) made up of patients operated on for uterine and/or adnexal pathologies, and Group 2 (60 patients) made up of patients treated for pelvic organ prolapse. RESULTS: In Group 1, median docking time (DT) was 5 min and median console time (CT) was 90 min. In two patients (2.6%) redocking was necessary. In two patients (2.6%), the surgeon continued the surgery laparoscopically. Intraoperative complications occurred in two surgeries (2.6%). In Group 2, median DT was 4 min and median CT was 134.5 min. In three patients (5%), redocking was necessary. In all patients, the surgery was successfully completed robotically without intraoperative complications. CONCLUSIONS: The present study demonstrates that the new HUGO RAS system for gynecologic surgery is safe with good results in terms of surgical efficacy and perioperative outcomes. Further studies are needed to investigate its use in other technical and surgical aspects.
