Opis:
Neoplasms of the head and neck stands for 6th most common malignant neoplasms in terms of morbidity in Poland. The effectiveness of the treatment depends on the complete resection and presence of the lymphatic metastases, detection of which might not be possible at the moment of diagnosis. Routine performance of the elective neck dissection among patients without lymphadenopathy (cN0) may favour the occurrence of surgical complication and seems to be too invasive procedure, particularly in group with non-advanced tumours (cT1-2). The sentinel lymph node biopsy is diagnostic procedure, which allows to exclude presence of metastases in nodes draining lymph directly from primary tumour. This technique let for a limitation of the extent of the procedure and the evaluation of the lymphatic tissue under the microscope in order to exclude presence of neoplastic cells. Sentinel lymph node biopsy is commonly use among patients with malignant melanoma of the skin and breast cancer. Multiple studies prove its usefulness during treatment of patients with head and neck cancer.

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:
The presence of metastases in the lymph nodes of the axillary fossa is the most important prognostic factor in patients with breast cancer. The surgical treatment option required for evaluation of the condition of the axillary lymph nodes depends on the results of a preoperative physical examination of the patients. The aim of the study was to evaluate the correctness of breast cancer patients’ qualification to surgical procedures allowing for evaluation of the condition of the axillary lymph nodes. Material and methods. A retrospective analysis of a group of 963 patients with a diagnosed malignancy of the breast, treated surgically in the period from 01 Jan 2011 to 29 Feb 2012. Depending on the result of evaluation of the axillary lymph node clinical condition, the patients underwent sentinel lymph node biopsy or elective axillary lymphadenectomy. Results. In 27.4% of patients subjected to excision of the sentinel lymph node, metastatic lesions were found in the lymph nodes removed during the procedure. In most cases (98.1%) that concerned the lymph nodes of the lower part of the axilla. In 17.4% of patients, metastases were located also in the middle or upper part (9%). In the group of patients primarily qualified to lymphadenectomy, the metastatic lesions in the axillary lymph nodes were diagnosed in 67.2% of patients. They were most commonly located in the lower part of the axillary fossa (in 96.7% of cases), and in 68.8% of patients in the middle or upper part (35.8%). Conclusions. Biopsy of the sentinel lymph node in patients with clinically advanced breast cancer is an effective and safe method of evaluation of the condition of the axillary fossa lymph nodes. A high rate of false positive results concerning the clinical stage of the disease requires changing the rules of patients’ qualification to elective axillary lymphadenectomy.
