The availability of radioisotopes for sentinel lymph node biopsy (SLNB) in breast carcinoma is limited in low- and middle-income countries and thus the need for other reliable tracers exists. We aimed to validate the effectiveness of fluorescein sodium (FS) together with methylene blue dye (MBD) for patients with node-negative early breast carcinoma in a prospective cross-sectional study. Patients underwent SLNB using FS and MBD followed by axillary dissection to validate results. Sentinel lymph node (SLN) identification rate and false negative rate were assessed for all three tracers/combinations (MBD, FS, and MBD + FS). We concluded that SLNB using a combination of FS and MBD has an acceptable rate of SLN identification but the addition of FS provided no additional benefit.

Carcinosarcoma (CS), also known as metaplastic breast carcinoma with mesenchymal differentiation, is one of the five distinct subtypes of metaplastic breast cancer. It is considered as a mixed, biphasic neoplasm consisting of a carcinomatous component combined with a malignant nonepithelial element of mesenchymal origin without an intermediate transition zone. Although cellular origin of this neoplasm remains controversial, most researchers declare that neoplastic cells derive from a cellular structure with potential biphasic differentiation.

The prognosis for esophageal cancer is determined in particular by the depth of infiltration (T stage) and lymph node metastasis (N status). In patients with locally advanced tumors, surgical resection is the current standard. The extent of the lymphadenectomy depends on the localization of the tumor, analogous to the choice of surgical technique.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.

Purpose: The purpose of this study was to evaluate the feasibility and safety of indocyanine green (ICG) fluorescence as an alternative to traditional sentinel lymph node biopsy (SLNB) techniques in breast cancer (BC) patients undergoing neoadjuvant chemotherapy (NAC). Specifically, the study aimed to assess sentinel node identification rates and the effectiveness of ICG in axillary staging without the use of radioactive tracers.

Methods: This retrospective study included 71 BC patients treated with NAC, who underwent SLNB using ICG fluorescence between 2020 and 2024.
