AI Article Synopsis
- The study focuses on cutaneous melanoma, highlighting the importance of Breslow micrometric measurement for treatment planning and survival assessment.
- Researchers analyzed 227 melanoma cases to assess the relationship between tumor size, Breslow index, and other known prognostic factors concerning sentinel lymph node outcomes.
- Results showed that while macroscopic tumor size correlated with sentinel lymph node results in univariate analysis, it was not significant in multivariate analysis, confirming that Breslow thickness is the primary predictor for both sentinel lymph node outcome and melanoma-specific survival.
Article Abstract
Background: Cutaneous melanoma is characterized by a high risk of metastasis to distant organs and a substantial mortality rate. For planning treatment and assessing outcomes, the Breslow micrometric measurement is critical. The tumor macroscopic dimension is not considered a prognostic parameter in cutaneous melanoma, although there are studies showing that tumor size is an independent prognostic factor for melanoma-specific survival. Therefore, this study aimed to evaluate the macroscopic dimension of melanoma and other known prognostic factors (i.e., Breslow index, mitoses, regression, and ulceration) as predictors of sentinel lymph node outcome and survival outcome.
Methods: We performed a retrospective cross-sectional study of 227 melanoma lesions subjected to sentinel lymph node biopsy at two Brazilian referral centers.
Results: On univariate analysis, there was a statistically significant correlation between the largest macroscopic tumor dimension and the sentinel lymph node result (P = 0.001); however, on multivariate analysis considering all evaluated parameters, there was no significant difference between the sentinel lymph node result and the tumor macroscopic dimension (P = 0.2689). Regarding melanoma-specific survival, the macroscopic dimension showed no significant correlation (P = 0.4632) in contrast to Breslow's dimension (P < 0.0001).
Conclusion: The Breslow thickness was the only significant factor related to both the sentinel lymph node outcome and melanoma specific survival among the evaluated variables.

Intraoperative methylene blue staining is effective as a single mapping technique in the identification of sentinel lymph nodes in dogs with low-grade mast cell tumours.
J Small Anim Pract

Department of Veterinary Medical Sciences, University of Bologna, Bologna, Italy.
Objectives: The aim of this prospective study was to assess the association between methylene blue staining pattern and the presence of histologic nodal metastasis in dogs with low-grade mast cell tumour in low-resource settings for the efficient diagnosis of lymphatic spread.
Methods: Dogs with a single, cytologically low-grade mast cell tumour and no documented distant metastases were prospectively included and underwent surgery. Along with primary mast cell tumour removal, intraoperative sentinel lymph node mapping with peritumoral mast cell tumour injection and regional lymph node excision, regardless of whether blue dye was visible in the lymph node, were performed.
The Patent Blue V Paradox: Hidden Offender, Serial Culprit.

From the Department of Allergy and Clinical Immunology, Unidade Local de Saúde de São João, Porto, Portugal.
Patent Blue V (PBV) is extensively used in sentinel lymph node identification in cancer surgery, potentially leading to an increased incidence of hypersensitivity reactions. A retrospective analysis was conducted on patients with suspected PBV hypersensitivity, at our center from 2010 to 2023. Skin prick tests (SPT) were performed on all patients, followed by intradermal tests (IDT) if SPT was negative.

Purpose Of Review: This review aims to explore the evolving management strategies for stage III melanoma, focusing on the comparative effectiveness of traditional surgical approaches like complete lymph node dissection (CLND) versus modern adjuvant therapies. It also examines the latest evidence on the efficacy, risks, and complications of these strategies, emphasizing the role of shared decision-making between patients and clinicians.
Recent Findings: Recent clinical trials and meta-analyses, including the MSLT-II and DeCOG-SLT studies, have demonstrated that CLND may not significantly improve survival outcomes in melanoma patients with sentinel lymph node biopsy (SLNB)-positive status.

Background: Primary breast squamous cell carcinoma (PBSCC) is a unique histopathological type of breast cancer. The majority of current case reports of PBSCC are triple-negative tumors with poor prognosis. Due to its heterogeneous clinical course, no unified management is achieved.

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.
