The prognosis of pancreatic carcinoma is dismal. Its main reason can be attributed to the difficult early diagnosis. In fact, at diagnosis most patients show advanced disease. In recent years, studies on the biomolecular characteristics of this disease have been conducted. The obtained results have favored the understanding of the basic mechanisms of the biologic aggressiveness and the resistance to chemoradiation of pancreatic carcinoma. They include the frequent oncogene activation as well as the similarly frequent suppressor gene inhibition. Based on this new knowledge, novel therapeutic strategies have been identified and treatments of targeting the ras oncoprotein or mutated p53, metalloproteinase inhibitors and tyrosine kinase receptor inhibitors (trastuzumab and cetuximab) together with antiangiogenic therapies are under experimentation.

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value. Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations.

Background Aims: The role of adjuvant transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) following curative resection remains controversial. We aimed to determine the effectiveness of postoperative adjuvant TACE in HCC patients.
Approach Results: In this randomized phase 3 trial, histologically confirmed HCC patients (AJCC TNM stage I and II) were randomly assigned (1:1) to adjuvant TACE or observation groups.

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.

Pancreatic ductal adenocarcinoma (PDAC) is projected to be the second leading cause of cancer-related death by 2030. Early identification is rare, with a 5-year overall survival (OS) of less than 10%. Advances in the understanding of PDAC tumor biology are needed to improve these outcomes.
