Does Smoking Cessation at Primary Diagnosis Reduce the Recurrence Risk of Nonmuscle-Invasive Bladder Cancer? Results of a Prospective Study.

2020

<b><i>Introduction:</i></b> Evidence that smoking cessation at first diagnosis of nonmuscle-invasive bladder cancer (NMIBC) reduces the risk of recurrence is lacking. The aim of our prospective study was to analyze the association between patients’ changes in smoking habits after diagnosis and recurrence-free survival (RFS). <b><i>Patients:</i></b> After transurethral resection of primary NMIBC, patients were classified as “ex-smokers,” i.e., those definitively stopping, and as “active smokers,” i.e., those continuing or restarting to smoke. Smoking status was reassessed every 3 months during the first year and every 6 months thereafter. Data …

Primary intraosseous squamous cell carcinoma arising from an odontogenic keratocyst: case series and literature review

2020

Background The aim of this study was to investigate the clinicopathologic features of primary intraosseous squamous cell carcinoma arising from an odontogenic keratocyst (PIOSCC ex OKC) and comprehensively improve the understanding of this disease. Material and Methods We retrospectively investigated five cases of PIOSCC ex OKC at Peking University School and Hospital of Stomatology. We also conducted a systematic review of studies on PIOSCC ex OKC by using online databases from their inception until February 2020. Results In our series of five cases, all lesions were located in the mandible. Three cases (60%) showed recurrent OKCs and two cases (40%) showed primary OKCs. During the follow-…

THE ROLE OF ENDOSCOPY IN ACUTE RECURRENT AND CHRONIC PANCREATITIS AND PANCREATIC CANCER

1999

Endoscopy plays an important role in the diagnosis and treatment of acute and chronic pancreatitis as well as pancreatic cancer. Sphincterotomy and stone removal in biliary pancreatitis, stone extraction and drainage in chronic pancreatitis, and stent implantation in pancreatic cancer are the predominant procedures. With endoscopy, minimal invasive techniques are at hand to solve urgent and long term problems.

Safety and Feasibility of Robotic-Assisted Drainage of Symptomatic Pancreatic Pseudocysts: A Case-Series Analysis (with video).

2021

Background: The surgical treatment of pancreatic pseudocysts (PPs) in patients who fail nonoperative management has evolved from aggressive open to a minimally invasive approach. The application of robotic surgery in this setting is scarcely reported. The aim of this study is to analyze the safety and feasibility of the robotic approach to pancreatic pseudocyst drainage. Methods: A single centre retrospective review of consecutive patients undergoing robotic-assisted pancreatic pseudocyst surgeries in an academic tertiary institution was performed. Results: There were 14 patients studied, of whom 10 underwent cystogastrostomy and 4 Roux-En- Y cystojejunostomy. Eight patients had gallstone p…

Influence of Lymphangio (L), Vascular (V), and Perineural (Pn) Invasion on Recurrence and Survival of Resected Intrahepatic Cholangiocarcinoma

2021

(1) Background: Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy. Besides tumor, nodal, and metastatic status, the UICC TNM classification describes further parameters such as lymphangio- (L0/L1), vascular (V0/V1/V2), and perineural invasion (Pn0/Pn1). The aim of this study was to analyze the influence of these parameters on recurrence and survival. (2) Methods: All surgical explorations for patients with ICC between January 2008 and June 2018 were collected and further analyzed in our institutional database. Statistical analyses focused on perineural, lymphangio-, and vascular invasion examined histologically and their influence on tumor recurrence and survival. (3) Results: Of 2…

Evaluation of atrial function by 2D strain echocardiography in patients with atrial fibrillation

2012

Abstract Objectives To evaluate atrial function by 2D strain in patients with atrial fibrillation (AF) and normal or slightly increased atrial size and to verify whether lower atrial strain is associated with more frequent AF recurrences. Materials and methods We studied 50 patients with AF, mean age 59.6 ± 13 years and 50 age-and gender-matched controls. We analyzed left atrial function through 2Dstrain imaging, after the re-establishment of sinus rhythm (SR) and we investigated about the recurrences of the arrhythmia. Results Atrial strain (AS) was lower in AF patients vs controls (LA p Conclusions The assessment of atrial function by strain imaging might help to identify patients who nee…

Effects of the number of removed lymph nodes on survival outcome in patients with sentinel node-negative breast cancer.

2021

Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant ther…

Endoluminal sonography in follow-up of rectal carcinoma.

1989

Fourteen patients who had undergone local excision, anterior resection or low anterior resection for rectal carcinoma were examined by endoscopic ultrasonography. In two of three cases of local recurrent carcinomas, endoscopic sonography was superior to computed tomography in determining the depth of tumor infiltration. There were difficulties in differentiating scar tissue from local tumor formation when the mucosa appeared normal upon endoscopic examination. Only repeated follow-up examinations starting in the postoperative period, will allow a differentiation between scar tissue and local tumor recurrence.

Repeated resection for recurrent intrahepatic cholangiocarcinoma: A retrospective German multicentre study.

2020

Background Tumour recurrence is common after resection of intrahepatic cholangiocarcinoma (ICC). Repeated resection is a potential curative treatment, but outcomes are not well-defined thus far. The aim of this retrospective multicentre cohort study was to show the feasibility and survival of repeated resection of ICC recurrence. Methods Data were collected from 18 German hepato-pancreatico-biliary centres for patients who underwent repeated exploration of recurrent ICC between January 2008 and December 2017. Primary end points were overall (OS) and recurrence-free survival from the day of primary and repeated resection. Results Of 156 patients who underwent repeated exploration for recurre…
