Opis:
Introduction: Cutaneous melanoma is estimated for 2% of malignant neoplasms occurring in humans. It is characterized by a high level of malignancy and low sensitivity to cytostatic drugs. The incidence of cutaneous melanoma is increasing in Poland. The lymphatic system is the most common route of dissemination of this neoplasm. The appearance of a sentinel node biopsy technique has made it possible to identify patients with a regionally advanced disease. It is a minimally invasive method with a small percentage of complications. Aim: Analysis of disease free survival (DFS) in cutaneous melanoma patients with sentinel lymph node biopsy. Material and methods: The analysis included 222 patients with cutaneous melanoma treated in the Department of Oncological Surgery in 2010–2015, who underwent a sentinel node biopsy. The study group consisted of 136 women and 86 men, the average age of patients was 59 years. Patients were qualified for sentinel node biopsy based on clinical evaluation and ultrasound of regional lymph nodes. The average follow-up was 25.1 months. About 2 hours before surgery, patients received a radioisotope, then lymphoscintigraphy SPECT was performed. Additionally, they were administered the Patent Blue dye in the operating room. Results: The sentinel node was identified in 217 patients (98%), and the average sentinel nodes were 2.25. Twenty-seven patients (12%) had a metastasis in sentinel nodes. In this group, the duration of symptom free survival was significantly shorter. Sentinel node status and age of the patient were independent factors affecting the prognosis of disease free survival. Conclusions: Sentinel node biopsy is a precise method to identify patients with cutaneous melanoma who have metastasis to regional lymph nodes, as well as the most important prognostic factor.

Opis:
Although both uveal (UM) and cutaneous (CM) melanoma cells derive from the transformed melanocytes, their biology varies significantly in several aspects. Malignant transformation is frequently associated with alternations in cell glycosylation, in particular those concerning branched complex-type N-glycans. These changes occur principally in β1,4-N-acetylglucosaminyltransferase III (GnT-III) that catalyzes the synthesis of glycans with bisected N-acetylglucosamine (GlcNAc) and β1,6-N-acetylglucosaminyltransferase V (GnT-V) that is involved in forming β1,6-branched antenna in complex-type glycans. We searched for the reasons of a different behavior of CM and UM cells in the expression of GnT-III and GnT-V and their oligosaccharide products. Our study showed that UM cells have more β1,6-branched glycans than CM cells, what results from a higher expression of MGAT5 gene encoding GnT-V. The higher β1,6-branching of glycans in UM may contribute to their higher potential to migrate on fibronectin and weaker binding to main extracellular matrix proteins, observed in our previous studies.
