Tumor Load

Although sentinel lymph node biopsy (SLNB) has proved to be able to diagnose axillary lymph node status safely and reliably, there is still not enough evidence to suggest that it can be used in patients who have undergone neoadjuvant chemotherapy (NAC) for lymph node-sparing surgery. The present study used molecular approaches to determine whether SLNB can be reliably used in patients who have been treated with NAC before SLN surgery, and whether the total tumor load of the SLN can be used as a predictive factor in axillary lymphadenectomy (ALD). We used one-step nucleic acid amplification (OSNA) to analyze a total of 111 consecutive patients who presented operable invasive breast carcinomas and who had been treated with NAC. SLN was positive in 55 patients and the identification rate was 100%. In 9 of these 55 patients, ALD showed that other lymph nodes were also involved. In all of the other 46 patients, the only lymph node to be identified as positive was SLN. Metastasis was not found in any of the axillary lymph nodes in the isolated tumor cell group. The total tumor load, defined as the amount of cytokeratin 19 mRNA copy numbers in all positives SLN (copies/µL), showed three risk groups related to the possibility of positive non-sentinel nodes. OSNA is a diagnostic technique that is highly sensitive, specific, and reproducible and it can be used to analyze sentinel lymph nodes after NAC. Total tumor load may be able to help predict additional metastases in axillary lymphadenectomy.

ObjectiveWe compared ultrastaging and one-step nucleic acid amplification (OSNA) examination of sentinel lymph nodes in two homogeneous patient populations diagnosed with early stage cervical cancer. The primary aim of our study was to evaluate the rate and type of sentinel lymph node metastases detected by ultrastaging and OSNA assay. Secondary aims were to define the sensitivity and the negative predictive value of sentinel lymph node biopsy assessed with OSNA and ultrastaging and to define the role of sentinel lymph node assessment in predicting non-sentinel lymph node status.MethodsConsecutive patients who underwent surgery (radical hysterectomy or trachelectomy or cervical conization) at our institution, between January 2018 and March 2020, were enrolled. All patients had a preoperative diagnosis of early-stage cervical carcinoma (International Federation of Gynecology and Obstetrics (FIGO) 2018 stages IA–IIB) and underwent sentinel lymph node assessment with ultrastaging or OSNA. Patients with advanced FIGO stages and special histology subtypes (other than squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma) or patients with sentinel lymph nodes analyzed only with hematoxylin and eosin were excluded. Clinical data were compared using the χ2 test and Fisher’s exact test. A κ coefficient was determined with respect to lymph node assessment. A p value <0.05 was considered statistically significant.ResultsA total of 116 patients were included in this retrospective analysis (53 ultrastaging, 63 OSNA). Overall, 531 and 605 lymph nodes were removed in the ultrastaging and OSNA groups, respectively, and 140 and 129 sentinel lymph nodes were analyzed in the ultrastaging and OSNA groups, respectively. 22 patients had metastatic sentinel lymph nodes: 6 (11.3%) of 53 patients in the ultrastaging group and 16 (25.4%) of 63 patients in the OSNA group. The total amount of positive SLNs was 7 (5%) of 140 in the ultrastaging group and 21 (16.3%) of 129 in the OSNA group, respectively (p=0.0047). Pelvic lymphadenectomy was performed in 26 (49.1%) of 53 patients in the ultrastaging group and in 34 (54%) of 63 patients in the OSNA group due to comorbidities. Metastatic non-sentinel lymph nodes were found in 4 patients: 2 (7.7%) of 26 patients in the ultrastaging group and 2 (5.9%) of 34 patients in the OSNA group, respectively. The total amount of positive pelvic lymph nodes was 3 (0.6%) of 531 in the ultrastaging group and 4 (0.7%) of 605 in the OSNA group (p=0.61). In the OSNA group, only 2 patients with negative sentinel lymph nodes had metastatic disease in the pelvic lymph nodes. By contrast, no patients with OSNA-positive sentinel lymph nodes had metastases in the pelvic lymph nodes. In the ultrastaging group, all patients with negative sentinel lymph nodes did not have metastatic disease in other pelvic lymph nodes.ConclusionsOSNA assessment of sentinel lymph nodes was associated with a negative predictive value of 91% but poor reliability in detecting node metastases in non-sentinel pelvic lymph nodes. Of note, the ultrastaging protocol revealed higher sensitivity and more reliability in predicting pelvic non-sentinel lymph node status.

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.

Osna Method

The aim of the study was to compare the prognostic significance of lymph node status of patients with lung cancer analyzed by three different methods: hematoxylin and eosin (H&E), immunohistochemistry of cytokeratin 19 (IHC CK19), and One-Step Nucleic Acid Amplification (OSNA). The clinical relevance of the results was evaluated based on relation to prognosis; the disease-free interval (DFI) and overall survival (OS) were analyzed. During radical surgical treatment, a total of 1426 lymph nodes were obtained from 100 patients, creating 472 groups of nodes (4–5 groups per patient) and examined by H&E, IHC CK19 and OSNA. The median follow-up was 44 months. Concordant results on the lymph node status of the H&E, IHC CK19 and OSNA examinations were reported in 78% of patients. We recorded shorter OS in patients with positive results provided by both OSNA and H&E. The study demonstrated a higher percentage of detected micrometastases in lymph nodes by the OSNA method. However, the higher sensitivity of the OSNA, with the cut-off value 250 copies of mRNA of CK19/µL, resulted in a lower association of OSNA positivity with progress of the disease compared to H&E. Increasing the cut-off to 615 copies resulted in an increase in concordance between the OSNA and H&E, which means that the higher cut-off is more relevant in the case of lung tumors.

Axillary Lymphadenectomy

Biopsy of the sentinel lymphnode (SLNB), the first lymphnode to receive lymphatic drainage from the primary tumor, accurately predicts the axillary lymph node status and, when negative, obviates the need for axillary lymphadenectomy (AL). The aim of this study was, to verify the SLN localization in breast cancer through preoperative lymphoscintigraphy and intraoperative gamma-probe, as well as to demonstrate the benefits of such techniques in preventing complications of AL. Medical records of 228 patients with breast carcinoma, who were underwent SLN localization and, radioguided surgery, from March 2005 to December 2007 were analyzed retrospectively. Data regarding age, tumor characteristic, breast involved, type of surgery, radiopharmaceutical drainage pattern, axillary assessment (SLNB or AL) and number of lymph nodes dissected were collected. It was ascertained that radioguided surgery is a selective method of axillary assessment in breast cancer, which makes this technique a safe alternative to radical assessment of total dissection of axillary lymph nodes and its subsequent complications.

At the Centre Oscar Lambret, the anticancer centre of the North of France, sentinel lymph node (SLN) procedures are routinely performed for localized (T0–T1, N0, M0) breast carcinoma without any previous treatment, in order to prevent the deleterious effects of axillary lymph node dissection. The present study was undertaken to assess if the expression in the tumor of a panel of 19 genes would allow to predict histological SLN involvement. We looked at cytokeratin 19 (CK19), mucin-1 (MUC1), mammaglobin (MGB1), cyclin D1 (CCND1), the four members of the HER/ErbB growth factor receptor family (EGFR, HER2–4), insulin-like growth factor-1 receptor (IGF-1R), estradiol receptors (ERcx, ERβ), progesterone receptor (PR), vascular endothelial growth factors (VEGF, VEGF-C), urokinase-like plasminogen activator (uPA), matrix metalloproteinases 2 and 9 (MMP2, MMP9), ets-related transcription factor ERM, and E-cadherin (CDH1). Their expression was quantified by real-time RT-PCR in 134 breast cancer samples and the relationships with SLN metastases were analyzed. A slight increase (35–40%) in CK19 and HER3 expression was observed in the tumors of patients with SLN metastases compared to those of patients without metastases, even if neither CK19 expression nor HER3 expression allowed to distinguish patients with micrometastases from patients with macrometastases. We conclude that the tumoral expression of biological parameters involved in cell proliferation or playing a critical role in the metastatic process, including tumor invasion and angiogenesis, is not strongly associated with SLN metastases.

Background : Locally advanced breast carcinoma (LABC) includes a wide range of clinical scenarios- advanced primary tumors (T4), advanced nodal disease and inflammatory carcinomas(1). Traditionally, treatment of LABC included a combination of Chemotherapy, Radiation and Surgery(2). However, there has been a shift to Neoadjuvant Chemotherapy in recent times.(3) Histological status and the number of axillary lymph nodes with metastasis is one of the most important prognostic factors and most powerful predictor of recurrence and survival in patients of breast carcinoma and remains so, even after neo-adjuvant chemotherapy. (3) Information derived from the sentinel lymph node is considered valuable, with less discomfort to the patient when compared with axillary dissection.(4) However, its role in detecting nodal metastasis after neo-adjuvant chemotherapy in LABC is still debatable and definitive studies to evaluate its role are still evolving. (5) Materials and Methods: Patients of LABC were evaluated using ultrasonography (USG) of axilla. Neo-adjuvant chemotherapy (NACT) was administered and patients were reassessed by USG of axilla. Thirty patients with node negative axillary status were subjected to Sentinel lymph node mapping using isosulfan blue followed by Modified Radical Mastectomy and Axillary Lymph Node Dissection. Histopathological evaluation of stained and unstained lymph nodes done and the data, thus obtained, was statistically analysed.   Results: Sentinel lymph node biopsy performed using Isosulfan Blue dye alone, after neo-adjuvant chemotherapy predicts the status of axillary lymph nodes with low accuracy.   Conclusions: Further studies would be required to establish the role of sentinel lymph node biopsy in patients with LABC after NACT.
