Abrikossoff-Granulosazelltumor: Ein seltener Tumor des Oesophagus
1997
Es wird uber einen 41 jahrigen Patienten berichtet, bei dem eine abdominothorakale Oesophagusresektion durchgefuhrt wurde nachdem ein Granulosazelltumor der Speiserohre in der praoperativen Diagnostik als malignes Plattenepithelcarcinom verkannt worden war. Granulosazelltumoren des Oesophagus sind sehr seltene zumeist benigne Tumoren neuroektodermalen Ursprungs. Die Diagnose ergibt sich aus dem endoskopischen Aspekt und der histologischen Untersuchung und immunohistochemischen Aufarbeitung des Biopsats. Aufgrund der histologischen Eigenart des Tumors besteht Verwechslungsgefahr mit Plattenepithelcarcinomen.
Survival of patients with hepatocellular carcinoma in cirrhosis: a comparison of BCLC, CLIP and GRETCH staging systems
2008
A major problem in assessing the likelihood of survival of patients with hepatocellular carcinoma (HCC) arises from a lack of models capable of predicting outcome accurately.To compare the ability of the Italian score (CLIP), the French classification (GRETCH) and the Barcelona (BCLC) staging system in predicting survival in patients with HCC.We included 406 consecutive patients with cirrhosis and HCC. Seventy-eight per cent of patients had hepatitis C. Independent predictors of survival were identified using the Cox model.One-hundred and seventy-eight patients were treated, while 228 were untreated. The observed mortality was 60.1% in treated patients and 84.9% in untreated patients. Among…
Moderate hypofractionated helical tomotherapy for localized prostate cancer: preliminary report of an observational prospective study.
2019
Objective: To report preliminary findings of a phase II study exploring the clinical outcomes of moderate hypofractionated radiotherapy performed with helical tomotherapy (HT) using computed tomography–magnetic resonance imaging–based planning for localized prostate cancer. Methods: The phase II prospective study received ethics approval from our institutional ethics committee. A dose of 60 Gy/20 fractions for low–intermediate risk prostate cancer by means of HT was explored. Primary endpoints of the study were acute and late gastrointestinal (GI) and genitourinary (GU) toxicities. Secondary endpoints were quality of life and biochemical-free survival. Results: A total of 35 patients were i…
Comparison between Laparoscopic and Robotic Approach for Sentinel Lymph Node Biopsy in Endometrial Carcinoma Women
2022
Robotic surgery has been approved as an alternative to laparoscopy to improve surgical outcomes. There is neither a consensus nor a systematic assessment of the literature about the superiority of the robotic approach over the laparoscopic one for sentinel lymph node (SLN) biopsy in endometrial carcinoma (EC) women. Therefore, a systematic review and meta-analysis was performed to compare the laparoscopic and robotic approaches for SLN biopsy in EC patients. Five electronic databases were queried from their inception to May 2022 for peer-reviewed studies, comparing such approaches in SLN biopsy in EC patients. The rate of detected SLN, dissected SLN, intraoperative and postoperative complic…
IMAGING FINDINGS SYSTEMATIZATION AND IMAGING STAGING PROPOSAL IN BISPHOSPHONATES ASSOCIATED OSTEOMYLITIS/OSTEONECROSIS OF THE JAWS
2011
INTRODUZIONE I Bifosfonati (BPs), farmaci analoghi al pirofosfato, sono usati nel trattamento dell’osteoporosi, nella malattia di Paget, nel mieloma multiplo e nelle metastasi ossee. Sebbene siano molto utili nella sintomatologia osteolitica, dal 2003 è stata descritta la correlazione tra la loro somministrazione e l’insorgenza dell’osteonecrosi dei mascellari (BRONJ). Il nostro studio si propone di descrivere la superiorità delle immagini TC nei pazienti in cura con BPs affetti da BRONJ, e di raggruppare gli stessi in accordo con una classificazione radiologica basata sulla presenza o meno dei segni dell’osteomielite/osteonecrosi e delle successive complicanze. Si dimostra, inoltre, l’impo…
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…

Early-stage small-bowel adenocarcinoma: a review of local endoscopic therapy.
2005
Early adenocarcinomas in the small intestine are a rare entity. Most adenocarcinomas in the small intestine are diagnosed at a more advanced stage. After surgical resection, only 3 - 10 % are found in stage T1 and 0 - 3 % in stage Tis (high-grade intraepithelial neoplasia), resulting in an overall 3 - 13 % rate of early-stage small-intestinal adenocarcinomas. The diagnosis of early small-intestinal carcinoma by endoscopy is still very rare, although it will probably improve with the development of new endoscopic techniques. At present there have been only two studies and a few case reports on the treatment of early duodenal carcinoma by endoscopic resection. No major complications such as m…
Computerised tomography and magnetic resonance imaging of laryngeal squamous cell carcinoma: A practical approach
2017
Squamous cell carcinoma is the most common head and neck cancer. This review describes the state-of-the-art computerised tomography and magnetic resonance imaging protocols of the neck and the normal larynx anatomy, and provides a practical approach for the diagnosis and staging of laryngeal squamous cell carcinoma.
