Rate of false-negative findings in sentinel lymph node biopsy in patients with head and neck malignant melanoma.
2017
e17566 Background: Sentinel Lymph Node Biopsy (SLNB) is the standard procedure for malignant melanoma with a thicknes above 1mm. However, the benefits of this procedure have recently been questioned because of a high number of false negative findings. The aim of our study was to investigate the number of early recurrence in patients with negative SLNB. Methods: All patients with malignant melanoma of the head and neck region who underwent SLNB between 2010 and 2016 in our department were included and data reviewed retrospectively. Recurrence in the same cervical lymph node region of the previously extirpated sentinel lymph node (SLN) within one year was defined as primary false-negative. R…
Sentinel lymph node biopsy in T1/T2 squamous cell carcinomas of the tongue: A prospective study
2014
Commonly used staging procedures often cannot predict the absence of cervical metastases (CM) in squamous cell carcinomas (SCCs) of the oral cavity. Due to the high incidence of occult CM in numerous N0 cases in the clinic, an elective neck dissection (ND) is performed. The sentinel lymph node biopsy (SNB) is a common concept in the modern surgical therapy of malignancies. The present study evaluates the applicability of this concept for T1/T2-SCC of the tongue. In a prospective clinical study, 10 consecutive patients with T1/T2-SCC of the tongue and cN0 necks, were enrolled. Following sentinel lymph node (SLN) scintigraphy, all patients underwent SNB with a γ-probe and a subsequent ND. SNB…
Risk factors for recurrence after robot-assisted radical hysterectomy for early-stage cervical cancer: a multicenter retrospective study

This retrospective analysis aimed to assess the risk factors for recurrence in patients diagnosed with early-stage cervical cancer (&le
Clinical Practice Guideline on Melanoma From the Spanish Academy of Dermatology and Venereology (AEDV)
2020
El diagnóstico y tratamiento del melanoma en atención especializada es un campo en el que se han producido numerosos cambios. El objetivo de esta guía es ofrecer a los dermatólogos españoles una referencia para resolver las dudas clínicas más frecuentes basándose en la evidencia actual. Para la realización de esta guía se escogió a miembros del Grupo Español de Dermato-Oncología y Cirugía con experiencia en el tratamiento de estos tumores y con interés en participar en la elaboración de la guía. Se hizo una adaptación de las guías de práctica clínica existentes mediante el método ADAPTE: inicialmente se resumió el proceso de atención y se elaboraron las preguntas clínicas relevantes. Se sel…
Beyond sentinel node algorithm. Toward a more tailored surgery for cervical cancer patients
2016
none 12 Nowadays cervical cancer is frequently diagnosed at early stage. For these patients lymph node metastasis (LNM) is considered the most important prognostic factor. During the last decade many efforts have been made to reduce rate of complications associated with lymphadenectomy (LND). A great interest has arisen in sentinel lymph node (SLN) biopsy as a technique able to decrease number of LND performed and, at the same time, to assess lymph nodal status. High diagnostic performances have been reached thanks to SLN surgical algorithm. However, despite the efforts, about 25% of these patients undergo at least unilateral LND to meet NCCN recommendations. Data of women with Internationa…
Vulvar and Vaginal Cancers
2021
Vulvar cancer and vaginal cancer are relatively rare tumors, typically affecting elder women, although they still represent the fourth and fifth, respectively, most common cancers in the gynecologic oncology field. Treatment of the early stages includes surgery and radiotherapy (external beam radiotherapy and brachytherapy). The sentinel lymph node sampling procedure is becoming the new standard of care in vulvar cancer. Chemotherapy has a role in combination with radiotherapy for the locoregional management or as palliative therapy for stage IV patients.
A systematic review on external ear melanoma
2014
Summary Background External ear melanoma accounts for only 1% of all cutaneous melanomas, and data on its optimal management and prognosis are limited. Aim We aim to review the literature on external ear melanoma to guide surgeons in the treatment of this uncommon and peculiar pathology. Materials and methods A systematic review of English language studies on ear melanoma published from 1993 to 2013 was performed using the PubMed electronic database. Data on epidemiology, oncological treatment (tumor resection and regional lymph nodes management), and reconstruction were extrapolated from selected papers. Results The total number of patients was 858 (30 studies). The helix was the most comm…
Impact of Obesity on Sentinel Lymph Node Mapping in Patients with apparent Early-Stage Endometrial Cancer: The ObeLyX study
2022
Conflicting data exists on the impact of Body Mass Index (BMI) on sentinel lymph-node (SLN) detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate of SLN. In addition, we evaluated possible differences in terms of surgical management and "empty-packet dissection" rate among obese and non-obese patients.Multicenter, propensity-matched, retrospective study. Patients with apparent early-stage endometrial cancer were included. Study population was divided into women with BMI/≥ 30 (Group-1 and Group-2). To lower the selection bias, a propensity-matched analysis was performed. Matching was based on hist…
A large multicenter propensity match study of sentinel lymph node biopsy feasibility in endometrioid variants of endometrial cancer
2022
Introduction: Sentinel lymph node (SLN) biopsy algorithm has been routinely applied in all endometrial endometrioid tumors, however, no studies analyzed the feasibility of SLN mapping in endometrioid variants (EV), which included villoglandular, secretory, ciliated cell, mucinous, and squamous differentiation. This study aimed to demonstrate the feasibility of SLN biopsy in EV of EC. Materials and methods: All patients undergoing minimally invasive surgical treatment for early-stage EC were included in the study. Patients were divided into 2 study groups: Group 1 which included patients with EV, and Group 2 which included patients with typical endometrioid histology. A propensity match anal…
Sentinel node mapping in endometrial cancer: Tips and tricks to improve bilateral detection rate. The sentitricks study, a monocentric experience.
2020
Abstract Objective The objective of the study is to show some small tricks for bilateral sentinel lymph node (SLN) uptake in endometrial cancer. Materials and methods Each step of the sentinel lymph node technique was analyzed. The cervix was exposed through the use of vaginal valves and by Martin pliers stapling of the anterior cervical lip. Fifty mg Indocyanine Green (ICG) powder was diluted with 10 ml of physiological solution. The spinal needle was marked at 15 mm with a steri-strip. After 20 min from the administration, in case of no LNS identification, an additional 1 ml in the non-detected side was administered in the superficial cervical area. All cervical injections were made by a …
