Objectives: To determine the usefulness of sentinel lymph node biopsy in early stage vulvar cancer and to assess recurrences after surgical treatment with sentinel node identification or surgical treatment without sentinel node identification.
Methods: We reviewed the records of 55 patients with early stage vulvar cancer operated on between 1995 and 2005. A prospective series of 28 patients who underwent vulvectomy and lymphadenectomy with intraoperative sentinel lymph node identification between 2000 and 2005 (SLN group) was compared with a retrospective series of 27 patients who underwent vulvectomy and lymphadenectomy without sentinel node procedure between 1995 and 2000 (non-SLN group). Patients in the sentinel node identification group underwent preoperative lymphoscintigraphy (technetium-99 colloid albumin injection around the tumor) and intraoperative mapping with isosulfan blue dye.
Results: In the SLN group, 9 tumors were T1 and 19 were T2, with a total of 40 groins dissected and 9 positive nodes in 7 patients. Sixty-two sentinel lymph nodes were detected with a mean of 2.2 sentinel nodes per patient (range 0-4). A false negative case was found. In the non-SLN group, 7 tumors were T1 and 20 were T2, with a total of 49 groins dissected and 9 positive nodes in 6 patients. Recurrence occurred in 8 patients (28.6%) in the SLN group and in 6 (26.9%) in the non-SLN group (P=0.8).
Conclusions: Sentinel lymph node identification in early stage vulvar cancer is a feasible. Analysis of recurrence may allow considering this procedure as a possible alternative to inguino-femoral lymphadenectomy.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.

Breast cancer is one of the most common cancers diagnosed in both countries with high and low levels of socio-academic development. Routine, regular screening tests being introduced in an increasing number of countries make it possible to detect breast cancer at an early stage of development, as a result of which the trend in the incidence of metastatic breast cancer has been decreasing in recent years. The latest guidelines for the treatment of this tumor do not recommend axillary dissection, which limits the need for rapid assessment of the nodes during surgery.

: The EndoPredict assay has been widely used in recent years to estimate the risk of distant recurrence and the absolute chemotherapy benefit for patients with estrogen (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer. However, there are no well-defined criteria for selecting patients who may benefit from the test. The aim of this study was to develop a novel nomogram to estimate the probability of obtaining a high-risk EndoPredict result in clinical practice.

To evaluate the neoadjuvant chemotherapy (NACTx) process in breast cancer (BC), its significant treatment-related adverse events (trAEs), tumor clinical response rates, and surgical and pathological outcomes, and to analyze factors influencing cavity shaving and axillary lymph node dissection (ALND) following sentinel lymph node biopsy (SLNB). A comprehensive retrospective study was conducted at a single center on patients who received NACTx for BC between 2015 and 2021. Medical records of 242 patients were reviewed.

Introduction: Sentinel lymph node (SLN) detection is the technique of choice for staging early-stage breast cancer (BC). The preferred technique for SLN detection is labeling with the radioisotope Technetium-99 (Tc-99). Other methods have been evaluated, including methylene blue, magnetic tracers, iodine seeds, or fluorescent substances.
