Article Abstract
Aim: The aim of this study was to present one center experience in applying the SNOLL technique to patients with suspected occult breast lesions.
Background: In the last years, the widespread use of mammographic screening programs resulted in an increasing number of women with nonpalpable suspicious breast lesions requiring further examination. The new method called sentinel node and occult lesion localization (SNOLL) enables the intraoperative detection of nonpalpable breast tumors and sentinel node biopsy in one surgical procedure.
Materials And Methods: 46 patients with suspected malignant lesions or diagnosed non-palpable breast cancer were subjected to a pre-operative SNOLL procedure. The day before the surgery, they were administered two radiotracers: one to localize the tumor and the other to localize the sentinel node. During the surgery, the breast tumor and the sentinel node, which in most cases had been examined intraoperatively, were detected with a handheld gamma probe and resected under its control.
Results: All 46 (100%) patients had their occult breast lesions resected. Histopathologic examination revealed cancer in 40 patients: in situ in 2 cases, invasive in 38 cases. All these patients had their sentinel nodes examined. In one case only, the sentinel node could not be located with a gamma probe. Intraoperative tests showed the sentinel node to be metastatic in 5 patients, who were then given a simultaneous axillary lymphadenectomy. In addition, the final histopathologic examination revealed metastasis to the sentinel node in one patient, who had to be reoperated.
Conclusion: SNOLL is a modern technique that enables a precise intraoperative localization of non-palpable suspected malignant breast lesions in combination with a sentinel node biopsy. Extended application of intraoperative management leads to significant decrease in the number of reoperations performed in patients with early bread cancer.

Head and neck squamous cell carcinoma (HNSCC) are the most common type of head and neck tumor that severely threatens human health due to its highly aggressive nature and susceptibility to distant metastasis. The diagnosis of HNSCC currently relies on biopsy and histopathological examination of suspicious lesions. However, the early mucosal changes are subtle and difficult to detect by conventional oral examination.

Background: The lymphatic system is the major route of cancer metastasis, and sentinel lymph nodes (SLNs) are the first station for the spread of cancer cells. Accurate identification of SLNs by tracers during surgery is crucial for SLN biopsy and lymphadenectomy. However, conventional monomodal tracers such as blue dyes and carbon nanoparticles often induce a misjudgment of SLNs and thus are still unsatisfying for clinical applications.

Objective: To examine the distribution of non-sentinel lymph nodes (SLNs) and to determine the feasibility of omitting elective neck dissection (END) in cases of cT1/2N0 oral cancer presenting with SLN metastasis.
Methods: A prospective cohort of patients with cT1/2N0 oral cancer underwent SLN biopsy using a γ-probe alongside methylene blue staining, followed by subsequent END. The primary outcome variable was non-SLN metastasis, with its predictors evaluated through logistic regression analysis.
Objectives: To report the first cases of surgical staging for apparently early-stage endometrial cancer performed using the Versius® next-generation robotic surgical system (Cambridge Medical Robots [CMR] Surgical, Cambridge, UK).
Design: Prospective case series. Participants/Materials: Women who underwent surgical staging, including total hysterectomy, bilateral adnexectomy, and sentinel lymph node (SLN) biopsy, for apparently early-stage endometrial cancer using the Versius® next-generation robotic surgical system (CMR Surgical, Cambridge, UK).

BACKGROUND Human Papilloma Virus (HPV)-associated Vulvar Squamous Cell Carcinomas (VSCC) present more frequently in young women than HPV- independent tumors. Due to its association with HPV infection, the incidence of vulvar cancer is increasing in young women; however, during pregnancy, it is still extremely rare. CASE REPORT We present the case of a 36-year-old pregnant woman at 23 weeks of pregnancy, diagnosed with HPV 16-associated VSCC, Federation of Gynecology and Obstetrics (FIGO) stage IB.
