Sentinel node

Jie Sun, Jingang Zhang
PURPOSE: To evaluate the value of sentinel lymph node (SLN) identification using carbon nanoparticles in abdominal lymph node metastasis in elderly (>60 years old) patients with colorectal cancer. METHODS: Eighty patients admitted at Weihai Second Municipal Hospital affiliated to Qingdao University from November 2014 to February 2017 were selected and divided into the control group (n=40) and the observation group (n=40) using the random number method. The control group was treated with surgery, while the observation group was administered carbon nanoparticle tracer for intraoperative dye detection and positioning; the first to four black-stained lymph nodes were marked as SLN, then radical surgery for colorectal cancer was performed...

BACKGROUND: In colon cancer, appropriate tumour excision and associated lymphadenectomy directly impact recurrence and survival outcomes. Currently, there is no standard for mesenteric lymphadenectomy, with a lymph node yield of 12 acting as a surrogate quality marker. Our goal was to determine the safety and feasibility of indocyanine green (ICG) fluorescence imaging to demonstrate lymphatic drainage in colon cancer in a dose-escalation study. METHODS: A prospective pilot study of colon cancer patients undergoing curative laparoscopic resection was performed...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare cutaneous malignancy of neuroendocrine origin with a high propensity for lymph node metastasis. Sentinel lymph node (SLN) status is important for accurate staging; however, the optimal treatment following SLN biopsy, regardless of nodal status, remains unclear. METHODS: 150 patients with MCC who underwent SLN biopsy from 1995 to 2011 at 3 Mayo Clinic sites were reviewed. RESULTS: Of 150 patients with MCC who underwent SLN biopsy, 39 (26%) were positive and 111 (74%) were negative...

BACKGROUND: Recently there are efforts to use sentinel lymph node biopsy (SLNB) techniques after neoadjuvant chemotherapy (NAC) to minimize axillary surgery. However, studies have shown higher false negative rates in this scenario, which might result in inaccurate assessment of treatment response and patient prognosis as well as leaving residual disease behind. In this study, we describe the use of reflector-guided excision of the percutaneously biopsied node (PBN) as an aid to conventional SLNB and its predictor of the axillary status after NAC...

AIM: Accurate staging of penile cancer requires invasive methods such as sentinel node biopsy or lymphadenectomy (LAD). We assessed the value of [18 F]FDG PET/CT for non-invasive nodal staging in penile cancer (PC) patients before inguinal LAD. PATIENTS AND METHODS: 41 consecutive patients with PC (stage pT1 or higher, cN0) received [18 F]FDG PET/CT before undergoing bilateral modified or radical inguinal staging LAD. Lymph nodes with a visually increased [18 F]FDG uptake were classified as suspicious of lymph node metastases (LNM)...

BACKGROUND: Recent studies suggested that ALND (axillary lymph node dissection) can be avoided in breast cancer patients with limited SLN (sentinel lymph node) metastasis. However, these trials included only several invasive lobular carcinoma (ILC) cases, and the validity of omitting ALND for ILC remains controversial. Here, we examined whether omitting ALND is feasible in ILC treatment. METHODS: A total of 3771 breast cancer patients underwent surgery for breast cancer at the Aichi Cancer Center Hospital between January 2006 and December 2015...

BACKGROUND: The performance of a prototype novel digital single-photon emission computed tomography (SPECT) camera with multiple pixelated CZT detectors and high sensitivity collimators (Digital SPECT; Valiance X12 prototype, Molecular Dynamics) was evaluated in various clinical settings. Images obtained in the prototype system were compared to images from an analog camera fitted with high-resolution collimators. Clinical feasibility, image quality, and diagnostic performance of the prototype were evaluated in 36 SPECT studies in 35 patients including bone (n = 21), brain (n = 5), lung perfusion (n = 3), and parathyroid (n = 3) and one study each of sentinel node and labeled white blood cells...

PURPOSE: Sentinel-lymph-node (SLN) resection seems to minimize systematic axillary-lymph-node dissection (sALND) side effects in operated breast cancer patients. We explored whether SLN resection achieves similar therapeutic outcomes as sALND but with fewer side effects. METHODS: A randomized, controlled, open-label trial with parallel-group design compared sALND restricted to cases with positive SLN biopsy (test arm, n = 774) versus SLN biopsy followed by sALND (control arm, n = 770)...

BACKGROUND: Biological pathways underlying major depressive disorder (MDD) can be viewed as systems biology networks. The psycho-immune-neuroendocrine (PINE) network comprises central nervous, immune, endocrine and autonomic systems, integrating biological mechanisms of MDD. Such networks exhibit recurrent motifs with specific functions, including positive and negative feedback loops, and are subject to critical transitions, influenced by feedback loop transitions (FLTs). AIMS: We aim to identify critical feedback loops and their FLTs, as well sentinel network nodes (SNNs), key network nodes that drive FLTs, within the PINE network...

BACKGROUND: Lymph node metastasis is a significant predictive factor for disease recurrence and survival in cervical cancer patients. Given the importance of lymph node metastasis, it is imperative that patients harboring metastasis are identified and can undergo appropriate treatment. Sentinel lymph node (SLN) mapping has drawn attention as a lymph node mapping technique. We evaluated the feasibility and efficacy of (SLN) mapping using indocyanine green (ICG) in cervical cancer. METHODS: We performed a single-center, retrospective study of 103 surgically treated cervical cancer patients who underwent SLN mapping...

BACKGROUND: The immune response to melanoma is manifested locally by tumor-infiltrating lymphocytes (TILs). Men and women are known to have varying patterns of immunity, yet sex-specific prognostic implications of TILs have not been explored. METHODS: Patients with clinically localized primary melanoma ≥0.76mm in Breslow thickness who underwent sentinel lymph node (SLN) biopsy at our institution were identified. Association between TILs (absent, nonbrisk, and brisk) and SLN positivity was evaluated using logistic regression...

The applications of 2-deoxy-2-[18 F]fluoro-D-glucose positron emission tomography/X-ray computed tomography (PET/CT) in the management of patients with breast cancer have been extensively studied. According to these studies, PET/CT is not routinely performed for the diagnosis of primary breast cancer, although PET/CT in specific subtypes of breast cancer correlates with histopathologic features of the primary tumor. PET/CT can detect metastases to mediastinal, axial, and internal mammary nodes, but it cannot replace the sentinel node biopsy...
