Use of inhibitors of the renin-angiotensin system is associated with longer survival in patients with hepatocellular carcinoma.
2016
Inhibition of the renin-angiotensin system (RAS) was associated with longer survival in patients with different solid malignancies.The objective of this study was to investigate the effect of RAS inhibitor (RASi) treatment (angiotensin-converting enzyme inhibitors or angiotensin-II-receptor blockers) on survival of patients with hepatocellular carcinoma (HCC).Patients diagnosed with HCC and Child-Pugh A between 1992 and 2013 who received sorafenib, experimental therapy, or best supportive care were eligible for the Vienna cohort. The Mainz cohort included patients with HCC and Child-Pugh A who received sorafenib treatment between 2007 and 2016. The association between RASi and overall survi…

The use of neural networks in identifying risk factors for lymph node metastasis and recommending management of t1b esophageal cancer.
2012
The objective of this study was to establish a prediction model of lymph node status in T1b esophageal carcinoma and define the best squamous and adenocarcinoma predictors. The literature lacks a satisfactory level of evidence of T1b esophageal cancer management. We performed an analysis pooling the effects of outcomes of 2098 patients enrolled into 37 retrospective studies using “neural networks” as data mining techniques. The percentages for lymph node, lymphatic (L1), and vascular (V1) invasion in Sm1 esophageal cancers were 24, 46, and 20 per cent, respectively. The same parameters apply to Sm2 with 34, 63, and 38 per cent as opposed to Sm3 with 51, 69, and 47 per cent. The respective …
What is the prognostic importance of lymphovascular space invasion in the absence of lymph node metastasis for early-stage endometrial cancer?
2021
Objective: The aim of this study is to analyze the prognostic role of lymph-vascular space invasion (LVSI), evaluated in a semi-quantitative fashion on prognosis of early stage, low risk endometrial cancer (EC). Methods: We enrolled patients who underwent surgery for endometrial cancer between 2003 and 2018 in two referral cancer center. All patients had endometrioid EC, G1–G2, with myometrial invasion <50%, and no lymph-node involvement. LVSI was analyzed in a semi-quantitative way, according to a 3-tiered scoring system in absent, focal and substantial. Results: Among 524 patients, any positive LVSI was found in 57 patients (10.9%) with focal LVSI (n=35, 6.7%) and substantial LVSI (n=2…
