Interobserver variability in rectum contouring in high-dose-rate brachytherapy for prostate cancer: A multi-institutional prospective analysis
2017
PURPOSE: The aim of this study was to evaluate the interobserver variability (KW) of rectum contouring, and its dosimetric consequences, for high-dose-rate brachytherapy in patients with prostate cancer across multiple institutions. METHODS AND MATERIALS: Five radiation oncologists contoured rectums in 10 patients on transperineal ultrasound image sets after establishing a delineation consensus. The D-0.1cc, D-1cc, and D-2cc rectum volume parameters were determined. The mean, standard deviation, and range of each dose-volume histogram parameter were evaluated for each patient. The JOY was determined using the coefficient of variation, and the dosimetric impacts on the total dose were analyz…
Prognostic Heterogeneity of Endosonographic T3 Rectal Cancer
2009
PURPOSE: This study aimed to assess the prognostic implications of uT3 rectal carcinomas according to the tumor thickness and to analyze the correlation between this ultrasound-based parameter and other prognostic factors. METHODS: Seventy-four patients with uT3(pM0) rectal tumors underwent primary surgery from 1996 to 2003. Preoperative endorectal ultrasound was used to assess uN stage, maximum tumor perimeter, and maximum tumor thickness. An ultrasound maximum tumor thickness cutoff point for local recurrence subdividing T3 tumors into uT3a and uT3b was established. RESULTS: Median follow-up was 41 months (range, 24-59). The 5-year actuarial local and overall recurrence rates were 9.82 pe…
Curative endoscopic resection of early esophageal adenocarcinomas (Barrett's cancer).
2005
Background In view of the increasing incidence of adenocarcinoma in Barrett's esophagus and the mortality and high morbidity rates associated with surgical therapy for this condition, safe and effective but less invasive methods of treatment are needed. Objective To evaluate efficacy and safety of endoscopic resection in these patients. Design Single-center prospective study. Setting Teaching hospital, conducted between October 1996 and September 2003. Patients A total of 100 consecutive patients (mean age, 62.1 ± 10.9 years; range, 31–86 years) with low-risk adenocarcinoma of the esophagus (macroscopic types I, IIa, IIb, and IIc; lesion diameter up to 20 mm; mucosal lesion without invasion…
The SIC-GIRCG 2013 Consensus Conference on Gastric Cancer.
2014
Abstract The topic chosen by the Board of the Italian Society of Surgery for the 2013 annual Consensus Conference was gastric cancer. With this purpose, under the direction of 2 chairmen, 36 experts nominated by the Regional Societies of Surgery and by the Italian Research Group for Gastric Cancer (GIRCG) participated in an experts consensus exercise, preceded by a questionnaire and mainly held by telematic vote, in accordance with the rules of the Delphi method. The results of this Consensus Conference, presented to the 115th National Congress of the Italian Society of Surgery, and approved in plenary session, are reported in the present paper.

Endoscopic ultrasonography and portal hypertension: where are we in 2009?
2009
Endoscopic ultrasonography is currently a sensitive diagnostic and therapeutic tool with established indications, but its role in the management of portal hypertension is not well defined. This article briefly reviews indications, technologic improvements, diagnostic and interventional applications of endoscopic ultrasonography in portal hypertension.
Detection of lymph node metastases in esophageal cancer.
2011
Lymph node status is the most important single prognostic factor in esophageal cancer. The detection of involved lymph nodes is therefore the key to cure. This article will provide a meta-analysis and metaregression analysis on the diagnostic performances of current lymph node-detection devices; discuss the recent status of the sentinel lymph node concept in esophageal cancer by the two sentinel node-mapping procedures (the radio-guided and the blue dye techniques) and the developing computed tomography (CT) lymphography; discuss the detection of micrometastases; and the potential clinical application of molecular-based patients' profiles. Combined use of endoscopic ultrasonography fine-nee…
