Article Abstract
Objectives: The main objective of this study is to analyze factors associated with nodal yield in level II-IV selective neck dissections (NDs) and the secondary objective is to assess its impact on overall and disease-free survival.
Methods: Observational retrospective study including adult patients submitted to level II-IV ND from January 2015 to December 2021 in the otorhinolaryngology department of a tertiary hospital center.
Results: A total of 44 patients and 78 level II-IV NDs (34 bilateral and 10 unilateral) were included. The median age at diagnosis was 60 (22-74) years, and 93.2% of the patients were male. A lower nodal yield was significantly associated with previous radiotherapy (p = 0.042) and extranodal invasion (p < 0.001) and was non-significantly associated with older age (p = 0.065). Furthermore, on a analysis adjusted to the cN status and age, the nodal yield was not associated with five-year disease-free survival (HR = 0.986; 95% CI = 0.922-1.054; p = 0.681) nor with five-year overall survival (HR = 1.006; 95% CI = 0.925-1.095; p = 0.888).
Conclusion: A reduced nodal yield in level II-IV NDs was significantly associated with previous radiotherapy and extranodal extension and non-significantly associated with age. There was no association between the nodal yield and five-year overall survival or disease-free survival.

Gynecologic Oncology Department, Clinic Hospital, Barcelona, Spain.
Purpose: To evaluate the detection rate of sentinel lymph node (SLN) mapping in early-stage ovarian cancer using [Tc]Tc-nanocolloid and indocyanine green (ICG), and the added value of an intraoperative gamma camera.
Methods: This was a prospective single-center trial of 63 patients with suspected early-stage epithelial ovarian cancer who underwent SLN mapping with combined tracers. [Tc]Tc-nanocolloid was injected into the ovarian ligaments before adnexectomy, and if malignancy was confirmed on intraoperative frozen section, ICG was administered after adnexectomy in immediate staging cases.

Objective: To evaluate the feasibility, safety, and quality of a standardized technique for single-port laparoscopic paraaortic lymphadenectomy guided by a novel anatomical concept.
Methods: This single-center prospective study enrolled patients with gynecological cancers requiring paraaortic lymphadenectomy from February 2022 to May 2025. All patients underwent single-port laparoscopic paraaortic lymphadenectomy using a standardized technique grounded in a novel "renal vein angle" anatomical concept.

Introduction: Depth of invasion (DOI) in vulvar squamous cell carcinoma (vSCC) predicts risk of nodal metastasis, with measurement >1 mm dictating the need for lymph node diagnostic procedures. In 2021, the International Federation of Gynecology and Obstetrics (FIGO) changed its advice on how pathologists measure DOI. Some organizations revised guidelines to this "New" method; others continued to endorse the FIGO 2009 "Old" method.

Background Although the Node Reporting and Data System (Node-RADS) offers a standardized method for assessing lymph node metastasis, its performance may vary according to the histologic type of breast cancer. Purpose To evaluate the applicability of the Node-RADS score in assessing axillary lymph node involvement in patients with invasive ductal carcinoma (IDC) or invasive lobular carcinoma (ILC). Materials and Methods In this retrospective study, data from consecutive women with pathologically confirmed IDC or ILC who underwent preoperative breast MRI between January 2017 and December 2018 were analyzed.

Purpose: To compare the outcomes between mastectomy (MAST) and breast-conserving surgery (BCS) in patients with metastatic breast cancer (dnMBC).
Methods: Patients diagnosed with dnMBC between 2010 and 2020 were retrospectively included. The chi-square test, binomial logistic regression, propensity score matching (PSM), Kaplan-Meier method, and multivariate Cox proportional analysis were used for statistical analyses.
