The newly developed radioisotope-free technique based on magnetic nanoparticle detection using a magnetic probe is a promising method for sentinel lymph node biopsy. In this study, a novel handheld magnetic probe with a permanent magnet and magnetic sensor is developed to detect the sentinel lymph nodes in breast cancer patients. An outstanding feature of the probe is the precise positioning of the sensor at the magnetic null point of the magnet, leading to highly sensitive measurements unaffected by the strong ambient magnetic fields of the magnet...

INTRODUCTION: Cutaneous melanoma is rare in childhood and published studies have mainly been retrospective single-institution series or small case series. Given the absence of clinical protocols dedicated to pediatric melanoma, the treatment approach is generally extrapolated from the ones applied to adults. METHODS: Coordinated by the European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT), this study collected patients prospectively registered between 2002 and 2012 under national cooperative projects dedicated to rare pediatric tumors in Italy, Poland, Germany, and France...

The purpose of this study was to investigate the effects and mechanisms of oxyresveratrol (Oxyres) on hepatocellular carcinoma (HCC) in vitro and in vivo. The MTT and Transwell assays were performed to investigate the effects of Oxyres on cell proliferation and migration of two HCC cell lines, QGY-7701 and SMMC-7721 cells. H22 cells were subcutaneously injected into hind foot pads of 70 male mice to establish a lymph node metastasis model. These mice were randomly divided into seven groups as follows, control group, HCC group, Oxyres 20 mg/kg group, Oxyres 40 mg/kg group, Oxyres 60 mg/kg group, Resveratrol (Res) group, and Adriamycin (ADM) group...

Management of the axilla in early breast cancer patients has significantly evolved in the last several decades. With the arrival of the sentinel lymph node biopsy, surgical practice for axillary staging in patients with early breast cancer has become gradually less invasive and formal axillary lymph node dissection has been confined to selected patients. Over the last two decades, evidence from randomized clinical trials have allowed for the de-escalation of axillary surgery in the management of early stage breast cancer...

The aim of the study was to perform cryosurgery on a primary breast tumor, coupled with simultaneous peritumoral and intratumoral tracer injection of a blue dye, to evaluate lymphatic mapping. We explored the ability of our strategy to prevent tumor cells, but not that of injected tracers, to migrate to the lymphovascular drainage during conventional resection of frozen breast malignancies. Seventeen patients aged 51 (14) years (mean [standard deviation]), presenting primary breast cancer with stage I to IV, were randomly selected and treated in The Rudolfinerhaus Private Clinic in Vienna, Austria, and included in this preliminary clinical study...

We investigate three aspects of the importance of nodes with respect to susceptible-infectious-removed (SIR) disease dynamics: influence maximization (the expected outbreak size given a set of seed nodes), the effect of vaccination (how much deleting nodes would reduce the expected outbreak size), and sentinel surveillance (how early an outbreak could be detected with sensors at a set of nodes). We calculate the exact expressions of these quantities, as functions of the SIR parameters, for all connected graphs of three to seven nodes...

The prime incision technique is an oncoplastic surgery aimed to remove both the breast tumor and the sentinel lymph node through one incision, thus providing better aesthetic results than the conventional breast conservative two incision technique. We retrospectively evaluated 2 cohorts of 60 consecutive breast cancer patients operated by either conventional breast conservative surgery (N = 26) or one incision surgery (N = 34). There were no recurrence or death events observed in any group. No difference was seen regarding the incidence of surgical complications...

Failure to detect recurrence and lymph node metastasis early represents a fundamental barrier to the improvement of survival rate in early stage oral squamous cell carcinoma (OSCC). The present study evaluated the association between serum interleukin-6 (IL-6) level and clinical outcomes in patients with early stage OSCC patients defined by sentinel node biopsy (SNB). A total of 53 patients with clinical stage I/II OSCC who underwent SNB were enrolled. SNB was determined by a radioisotope method, and was evaluated by histopathological examination and genetic analysis...

The intraoperative mapping of sentinel lymph nodes (SLNs) is part of the treatment strategy for a number of types of tumor. To retrospectively compare results from the mapping of pelvic SLNs for gynecological oncology, using distinct dyes, the present review was conducted to determine the clinical significance of SLN mapping for gynecological oncology. In addition, the present study aimed at identifying an improved choice for SLN mapping tracers in clinical application. Each dye exhibits demerits when applied in the clinical environment...

While the majority of cutaneous squamous cell carcinomas (cSCCs) can be treated surgically, the additional work-up and treatments indicated for high-risk cSCC remain undefined. In recent years, improvements in tumor staging systems have allowed for the more accurate stratification of tumors into high- and low-risk categories. This insight, along with the publication of cSCC guidelines, brings us closer to the development of a consensus approach. The second article in this continuing medical education series addresses in question and answer format the most common questions related to advanced and high-stage cSCCs, with a simplified flowchart...

BACKGROUND: Planar lymphoscintigraphy (PL) has a lower detection rate of sentinel lymph nodes (SLNs) in head and neck melanoma compared with other sites. We assessed situations when single-photon emission computed tomography/computed tomography (SPECT/CT) identified nodes not seen by PL. We also evaluated the impact of SPECT/CT on surgical approach and oncologic outcomes. METHODS: Patients who underwent SLN biopsy (SLNB) for head and neck melanoma with PL and SPECT/CT between November 2011 and December 2016 were included...

BACKGROUND: Intraoperative frozen sections (FS) of sentinel lymph nodes (SLN) were evaluated to avoid the need for deferred axillary lymph node dissection (ALND) in patients with early breast cancer (EBC). However, FS has low sensitivity for detecting micro-metastases (<2 mm), resulting in patients who later undergo deferred ALND. The aim of the study was to determine the best clinical approach for selecting patients who would derive real benefit from ALND, as well as to minimize the functional and psychological damage caused by delayed surgery, and the risk of undertreating EBC patients...

BACKGROUND: The standard surgical procedure for early-stage cervical cancer is abdominal radical hysterectomy, including pelvic lymphadenectomy. Currently, minimally invasive surgical techniques for early cervical cancer are progressing; total laparoscopic radical hysterectomy (TLRH) is a possible alternative to abdominal surgery. In addition, sentinel node navigation surgery (SNNS), which can prevent lower limb edema, has been widely used for radical hysterectomy. MATERIALS AND METHODS: A radioisotope is injected into the uterine cervix 1 day preoperatively and surgeons carefully identify the correct sentinel lymph nodes (SLNs) to prevent picking up the cervical gamma rays during surgery...

INTRODUCTION: Complete lymph node dissection (CLND) after a positive sentinel node (SN) biopsy provides important prognostic information in melanoma patients but has been questioned for therapeutic use recently. We explored whether quantification of the tumour spread to SNs may replace histopathology of non-sentinel nodes (NSNs) for staging purposes. PATIENTS AND METHODS: We quantified melanoma spread in SNs and NSNs in 128 patients undergoing CLND for a positive SN...

BACKGROUND: Indications for superficial inguinal lymph node (ILN) dissection in melanoma include fine needle aspiration or clinically positive ILN and sentinel lymph nodes (SLN). Open inguinal lymphadenectomy may be complicated by poor wound healing, deep vein thrombosis, and lymphedema. Technical considerations and case series of a novel surgical approach, robotic inguinal lymphadenectomy, are presented. METHODS: This is a case series of four robotic ILN dissections for melanoma at a tertiary care facility...

T regulatory cells (Tregs), involved in tumour tolerance, can generate Adenosine by CD39/CD73 surface enzymes, which identify four Tregs subsets: CD39+CD73- nTregs, CD39+CD73+ iTregs, CD39-CD73+ oTregs and CD39-CD73- xTregs. In melanoma patients, increased Tregs levels are detected in peripheral blood (PB), sentinel lymph node (SLN) and tumour infiltrating lymphocytes (TILs), but Adenosine role was not investigated yet. We examined total Tregs and Adenosine subsets in PB, SLN and TILs from melanoma patients (n = 32) and PB from healthy donors (HD; n = 10) by flow cytometry...
