Introduction: Sentinel node biopsy in breast cancer has been a standard procedure at the Institute for Oncology of Vojvodina since 1999 and we have done more than 700 biopsy. Before the introduction of axillary sentinel lymph node biopsy, lymph nodes were routinely dissected, and this approach was the gold standard in surgical treatment of breast cancer. The study was aimed at presenting our results in performing sentinel node biopsy in clinical practice for operative treatment in breast cancer.
Material And Methods: All patients (n = 791) were women with clinically T1-2, N0-1, M0 breast cancer. Sentinel lymph node marking was performed by both contrast blue dye (Patentblau V) and radiotracer (antimony sulfide marked with Tc99m). Both contrast media were applied peritumorally or periareolarly. After sentinel lymph node biopsy all patients underwent breast-conserving surgery or mastectomy with or without lymph node dissection of level I and II (depending on sentinel lymph node status).
Results: Sentinel lymph node biopsy was negative in 543 (68.7%) patients, and positive in 248 (31.3%) patients. Solitary tumor was present in 722 (91.2%) cases, multifocal tumors in 36 (4.57%), multicentric in 28 (3.55%) and bilateral in 5 (0.68%) patients. The mean duration of follow-up was 60.59 months (median 65, range 12-132). Distant metastases were mostly found in bones (39.13%).
Conclusion: The number of complications related to axillary dissection can be reduced and the patient's quality of life can be improved by avoiding complete axillary lymph node dissection.

Rosai-Dorfman disease (RDD) is a self-limited, idiopathic, non-neoplastic disorder characterized by the proliferation of phagocytic histiocytes, which can mimic malignant lymphoproliferative disease. Cases of RDD most commonly present as bilateral painless cervical lymphadenopathy, with lesser involvement of the axilla, inguinal, and mediastinal lymph nodes. We present the case of a 62-year-old woman with a history of endometrial serous carcinoma who underwent evaluation at a dedicated breast imaging department after positron emission tomography/computed tomography (PET/CT) revealed breast masses and axillary nodes with increased uptake of fluorodeoxyglucose (FDG).

Objective: The aim of this study was to evaluate the relationship between subclinical lymphedema identified prior to surgical intervention and clinical lymphedema observed in the late period, the incidence of lymphedema in our cohort, and the associated risk factors.
Materials And Methods: This prospective study was conducted with early-stage breast cancer patients who had been enrolled in a previous study. For diagnosing lymphedema, physical examination, L-Dex® score, and circumferential measurement was used.
Adverse Effects of Intraparenchymal and Peritumoral Application of Isosulfan Blue Dye in Sentinel Lymph Node Mapping in Breast Cancer: A Systematic Review and Meta-Analysis.

Department of General Surgery, Barking Havering and Redbridge University NHS Trust, London, England, United Kingdom.
We investigate the evidence for adverse effects of intraparenchymal and peritumoral application of isosulfan blue dye in sentinel lymph node (SLN) mapping in breast cancer patients. A meta-analysis on the adverse effects of intraparenchymal and peritumoral application of isosulfan application in SLN mapping was conducted using Medline and Embase databases up to 2023. Procedure-based adverse reactions were divided into three grades: Grade I (allergic skin reactions), Grade II (hypotension) and Grade III (requiring vasopressor support).

Objective: This study aimed to investigate the diagnostic value of 7-tumor associated autoantibodies (7-TAAB) and to evaluate the relationship between 7-TAAB and clinical features in esophageal squamous cell carcinoma (ESCC), which can be used to guide clinical diagnosis and treatment and achieve its clinical value.
Methods: (1) Blood specimens were collected from patients with ESCC who had not previously received antitumor therapy (ESCC group) and those who had normal medical check-ups in the hospital during the same period (control group). The concentrations of 7-TAAB (P53, PGP9.

Background: Radical cystectomy (RC) combined with pelvic lymph node dissection (PLND) is the standard treatment for muscle-invasive bladder cancer (MIBC). For metastatic MIBC patients, platinum-based chemotherapy remains the first choice treatment. However, approximately 50% of patients with metastatic MIBC are ineligible for platinum-based adjuvant chemotherapy because of impaired renal function.
