Background/aims: The prognosis remains unsatisfactory even if the patient undergoes extensive surgery, which is the only curative treatment for these tumors. Therefore, early detection and diagnosis are needed to improve long-term survival. To investigate the clinicopathological feature of extrahepatic cholangiocarcinoma in patients presenting without jaundice compared with the features of tumors in patients presenting with jaundice.
Methodology: This was a retrospective study of 50 patients resected for extrahepatic cholangiocarcinoma. There were 15 non-jaundiced (Group A) and 35 jaundiced patients (Group B). Data on demographic and clinical features, surgical procedures and pathological diagnoses were collected retrospectively.
Results: Preoperative mean serum levels of total bilirubin, aspartate aminotransferase, alanine aminotransaminase, alkaline phosphatase and gamma-glutamyltranspeptidase were statistically different between the groups. There was also a significant difference in the location of tumors. The distal tumors occurred in 9 non-jaundiced and 31 jaundiced patients (p=0.048). There were no significant differences between the characteristics and preoperative laboratory data of the patients with perihilar tumors and those with distal tumors.
Conclusions: We believe that finding the disease in asymptomatic and non-jaundiced patients is very important for their prognosis. Further studies are needed and efforts should also continue to identify patients with suspicious findings.

Epidermal growth factor (EGF) binds with its surface receptor to stimulate gene expression and cancer cell proliferation. EGF stimulates cancer cell growth via phosphoinositide 3‑kinase (PI3K) and programmed cell death ligand 1 (PD‑L1) pathways. As an integrin αvβ3 antagonist, heteronemin exhibits potent cytotoxic effects against cancer cells.

Background: Recent research indicates a role of gut microbiota in development and progression of life-threatening diseases such as cancer. Carcinomas of the biliary ducts, the so-called cholangiocarcinomas, are known for their aggressive tumor biology, implying poor prognosis of affected patients. An impact of the gut microbiota on cholangiocarcinoma development and progression is plausible due to the enterohepatic circulation and is therefore the subject of scientific debate, however evidence is still lacking.

Introduction: Molecular alterations in the PI3K/AKT and Ras/Raf/MEK/ERK pathways are frequently observed in patients with endometrial cancers. However, mTOR inhibitors, such as temsirolimus, have modest clinical benefits. In addition to inducing metabolic changes in cells, metformin activates AMPK, which in turn inhibits the mTOR pathway.

The cause was prolonged exposure to high concentrations of 1,2-dichloropropane that was included in the ink cleaning agent. Until then, it was not known that this substance could cause cancer in humans.

Purpose: To examine incidence trends and patterns for early- and late-onset liver cancer.
Methods: Liver and intrahepatic bile duct (IBD) cancers diagnosed between 2000 and 2019 were acquired from 22 SEER registries. Variables included early-onset (20-49) vs.
