Aim: In the management of early breast carcinoma, biopsy of sentinel lymph nodes has gradually replaced dissection of Level I and II axillary nodes. The aim of the study is to assess feasability and reliability of the method in our conditions.
Method: From June 1998 to June 2007, a total of 458 sentinel node biopsies (SLNB) were performed. Originally, patent blue sentinel node mapping was used. Since 2000, a combination of radiocolloid application and a gamma- probe (detector), as well as the patent blue, has been used. Originally, SLNBs were followed by axillary dissections, however, in 2002, the procedure was waived in cases of negative sentinel nodes findings.
Results: Out of the total of 458 SLNB patients, 382 female patients were included in the study. SLNB, without concomitant axillary dissection, was performed in 170 subjects. In 70 subjects, the sentinel node was positive and they were indicated for axillary dissections. Positive non-sentinel nodes were detected 17 times. In total, 899 sentinel nodes were examined in the study group of 382 biopsies. The mean was 2.35. False negative nodes were recorded in three cases in female patients with SLNB and axillary dissection (4.6%). No local relapses in the axilla were recorded in negative sentinel node findings without subsequent axillary dissections.
Conclusion: Sentinel node biopsy is a safe alternative to axillary dissection in the surgical management of early breast carcinoma.

Lymph node assessment at the time of robotic hysterectomy for endometrial intraepithelial neoplasia: A cost-effectiveness analysis.

Objective: We sought to determine the cost-effectiveness (CE) of lymph node dissection (LND) at the time of hysterectomy for endometrial intraepithelial neoplasia (EIN).
Methods: A decision analytic model was created to evaluate the strategies of routine full LND, sentinel lymph node dissection (SNLD), SNLD without advancing to full LND in the event of non-mapping, and full LND based on Mayo Criteria, versus no LND. Patients in the no LND group and those in the SLND group without advancement to full LND in the event of non-mapping who were found to have EC on final pathology and suspicious post-operative imaging underwent full LND.
Added prognostic value of sentinel lymph node mapping in endometrial cancer to molecular subgroups.

Objective: Treatment approaches for endometrial cancer became more personalized in the last decade, mainly due to two key advancements - sentinel lymph node (SLN) mapping and molecular classification. However, their prognostic interaction remains relatively unexplored.
Methods: This retrospective cohort study included patients with endometrial cancer, who underwent surgical treatment including SLN mapping at the Bern University Hospital, Switzerland.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

Background: There is compelling evidence that the incidence of melanoma in cigarette smokers is substantially lower than in non-smokers. However, the risks of both recurrence and death appear to be higher in smokers if melanoma does develop. The magnitude of these increased risks is poorly documented.
