Axillary Lymph

Axillary lymph node status is one of the most reliable prognostic factors of long-term survival in breast cancer surgery. Metastatic involvement of the axillary lymph nodes is also crucial in the decision making of potentially useful adjuvant treatment. Until the last decade, Axillary Lymph Nodes Dissection (ALND) was performed in order to obtain the regional lymphatic system staging. In case of non-metastatic spread, that kind of surgery was limited only to this purpose; no further oncological benefits were obtained and the patients were exposed to several comorbidities affecting this type of surgery. Complications after ALND are reported in 15-30% of cases. They are well known and range from early bleeding, infection, symptomatic nerve damage, and longstanding limb lymph-edema with an incredible impairment of the quality of life.The Sentinel Lymph Node (SLN) theory holds that the SLNs are the first nodes draining lymph from an anatomic region (i.e. the breast) where metastatic disease will most likely to be found. If that node is found to be cancer free, the entire lymphatic system is likely to be cancer free; if it is metastatic, there is an elevated chance of finding more metastatic nodes. Thanks to the application of this hypothesis, several patients over the last 10-15 years have avoided unnecessary major demolitive surgery. To obtain accurate evaluation of the SLN a multidisciplinary dedicated team is necessary. This procedure has been internationally validated and the false negative rate is nowadays less than 5% when performed by expert hands. Dedicated breast surgeons working in a high-volume centres are necessary to reach satisfactory confidence in performing this very specialised procedure in order to obtain an accurate staging. The number of women presenting to the breast oncology units is continuously increasing and the implementation of screening programs has been crucial in detecting numerous patients (more than 75%) with early disease and non-metastatic axillary lymph nodes. The practice of the SLN is clearly able to offer those patients an accurate staging with low comorbidities, preserving their quality of life.

This study aimed to determine whether bypass circulation was present in lymphedema and its effect. This was a retrospective, cross-sectional study. Patients who underwent unilateral breast cancer surgery with axillary lymph node dissection were recruited and underwent single-photon emission tomography/computed tomography (SPECT/CT). SPECT/CT was performed to detect the three-dimensional locations of radio-activated lymph nodes. Patients with radioactivity in anatomical locations other than axillary lymph nodes were classified into a positive group. All patients received complete decongestive therapy (CDT). Exclusion criteria were as follows: History of bilateral breast cancer surgery, cervical lymph node dissection history, and upper extremity amputation. The difference in the upper extremity circumference (cm) was measured at four points: Mid-point of the upper arm, elbow, and 10 and 15 cm below the elbow. Twenty-nine patients were included in this study. Fifteen patients (51.7%) had bypass lymphatic systems on the affected side, six (20.7%) had a bypass lymphatic system with axillary lymph nodes on the unaffected side, and 11 (37.9%) showed new lymphatic drainage. The positive group showed significantly less swelling than the negative group at the mid-arm, elbow, and 15 cm below the elbow. Bypass lymphatic circulation had two patterns: Infraclavicular lymph nodes and supraclavicular and/or cervical lymph nodes. Changes in lymph drainage caused by surgery triggered the activation of the superficial lymphatic drainage system to relieve lymphedema. Superficial lymphatic drainage has a connection through the deltopectoral groove.

Background and objectives: With improved diagnostic means of early breast cancer, the percentage of cases with metastasis in axillary lymph nodes has decreased from 50–75% to 15–30%. Lymphadenectomy and sentinel lymph node biopsy are not treatment procedures, as they aim at axillary nodal staging in breast cancer. Being surgical interventions, they can lead to various complications. Therefore, recently much attention has been paid to the identification of non-invasive methods for axillary nodal staging. In many countries, ultrasound is a first-line method to evaluate axillary lymph node status. The aim of this study was to evaluate the prognostic value of ultrasound in detecting intact axillary lymph nodes and to assess the accuracy of ultrasound in detecting a heavy nodal disease burden. The additional objective was to evaluate patients’ and tumor characteristics leading to false-negative results. Materials and Methods: A total of 227 women with newly diagnosed pT1 breast cancer were included to this prospective study conducted at the Breast Surgery Unit, Clinic of Surgery, Hospital of Lithuanian University of Health Sciences Kauno Klinikos, between May 1, 2016, and May 31, 2018. All patients underwent preoperative axillary ultrasound examination. Ultrasound data were compared with the results of histological examination. The accuracy and true-negative rate of ultrasound were calculated. The reasons of false-negative results were analyzed. Results: Of the 189 patients who had normally appearing axillary lymph nodes on preoperative ultrasound (PAUS-negative), 173 (91.5%) patients were also confirmed to have intact axillary lymph nodes (node-negative) by histological examination after surgery. The accuracy and the negative predictive value of ultrasound examination were 84.1% and 91.5%, respectively. In ≥3 node-positive cases, the accuracy and the negative predictive value increased to 88.7% and 98.3%, respectively. In total, false-negative results were found in 8.5% of the cases (n = 16); in the PAUS-negative group, false-negative results were recorded only in 1.6% of the cases (n = 3). The results of PAUS and pathological examination differed significantly between patients without and with lymphovascular invasion (LV0 vs. LV1, p < 0.001) as well as those showing no human epidermal growth factor receptor 2 (HER2) expression and patients with weakly or strongly expressed HER2 (HER2(0) vs. HER2(1), p = 0.024). Paired comparisons revealed that the true-negative rate was significantly different between the LV0 and LV1 groups (91% vs. 66.7%, p < 0.05), and the false-negative rate was statistically significant different between the HER2(0) and HER2(1) groups (10.5% vs. 1.2%, p < 0.05). Evaluation of other characteristics showed both the groups to be homogenous. Conclusions: Negative axillary ultrasound excluded axillary metastatic disease in 91.5% of the patients. PAUS had an accuracy of 88.7% in detecting a heavy nodal disease burden. With the absence of lymphovascular invasion (LV0), we can rely on PAUS examination that axillary lymph nodes are intact (PAUS-negative), and this patients’ group could avoid sentinel lymph node biopsy. Patients without HER2 expression are at a greater likelihood of false-negative results; therefore, the findings of ultrasound that axillary lymph nodes are intact (PAUS-negative results) should be interpreted with caution.

Abstract Objective To describe tattoo ink marking of axillary lymph nodes (TIMAN) and the elements leading to successful removal at sentinel lymph node biopsy (SLNB). Methods An IRB-approved retrospective image review was conducted of breast cancer patients who underwent SLNB after TIMAN from February 2013 to August 2017, noting patient and tattooed lymph node (TLN) features, initial biopsy type, time to surgery, if the TLN was identified at surgery, and correlation with the SLN. Cases were divided into two groups: the presurgical group, which had primary surgery, and the pre-neoadjuvant chemotherapy (NACT) group, which underwent surgery after completing NACT. Results Of 30 patients who underwent 32 TIMAN procedures, 10 (33.3%) were presurgical and 20 (66.7%) were pre-NACT. The average lymph node (LN) depth from the skin was 1.6 cm, with an average of 0.3 mL of tattoo ink injected. Of 32 procedures, 29 (90.6%) had US images demonstrating the injection. Of these, 10 (34.5%) were injected in the LN cortex surface and 19 (65.5%) in the middle cortex. Seven (24.1%) were injected in the LN lateral aspect, 12 (41.4%) in the mid aspect, and 10 (34.5%) in the medial aspect. Of 32 LNs, 28 (87.5%) were tattooed immediately after initial biopsy and 4 (12.5%) at a later date. At SLNB, all 32 (100%) TLNs were identified, all correlated with the SLN, and 10 (31.3%) were positive for cancer. Conclusion Using an average of 0.3 mL of tattoo ink, all TLNs were successfully identified for removal at surgery, despite variability in LN and injection factors.

AbstractThe 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.
