• How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

Researchers have developed a patient-derived cell line-based model to study how intratumor heterogeneity affects sensitivity of hepatocellular carcinoma (HCC) to different therapeutic agents, reported in the January issue of Gastroenterology. HCCs have a large amount of genetic heterogeneity within each tumor, making them difficult to treat. Multiple regions of tumors

  • Can Statin Use After Diagnosis of Esophageal Cancer Prolong Survival?

Can Statin Use After Diagnosis of Esophageal Cancer Prolong Survival?

Statin use after a diagnosis of esophageal adenocarcinoma, but not esophageal squamous cell carcinoma, reduces esophageal cancer–specific and all-cause mortality, researchers report in the April issue of Gastroenterology. Esophageal cancer is the fifth most common cause of cancer-related death in men and eighth most common cause in women, worldwide. Esophageal

  • Distinguishing a Pancreatic Pseudocyst from a Mucinous Cystic Neoplasm

Distinguishing a Pancreatic Pseudocyst from a Mucinous Cystic Neoplasm

Researchers describe the case of a patient with what appeared to be a pancreatic pseudocyst that was found to be a benign mucinous cystic neoplasm (MCN), based on analysis of a cyst wall biopsy. In the March issue of Gastroenterology, Katie Connor et al  describe a 22-year-old woman who came

Pancreaticobiliary Maljunction and Neuroendocrine Carcinoma

Researchers describe an unusual case—a patient with a neuroendocrine carcinoma of the gallbladder accompanied by pancreaticobiliary maljunction—in the March issue of Clinical Gastroenterology and Hepatology. Tomonori Matsumoto et al examined a 58-year-old man with epigastric pain. Computed tomography (A) and fluoro-2-deoxy-d-glucose positron emission tomography (B) revealed angular diffuse thickening of the gallbladder

  • Biomarker of Early-stage Aggressive Colon Cancer

Biomarker of Early-stage Aggressive Colon Cancer

Lack of the biomarker CDX2 identifies a subgroup of patients with high-risk stage II colon cancer who appeared to benefit from adjuvant chemotherapy. These patients are usually treated with surgery alone. The findings come from a study published online January 21 in the New England Journal of Medicine. Piero Dalerba

  • A Nanoparticle-based Approach to Selectively Target Hepatocellular Carcinomas

A Nanoparticle-based Approach to Selectively Target Hepatocellular Carcinomas

Researchers have created nanoparticles that selectively kill hepatoma cells and reduce growth of liver tumors in rats, they report in the February issue of Gastroenterology. They show that the particles induce tumor-specific necrosis by selectively disrupting redox balance within cancer cells. Dietary intake of the natural omega-3 fatty acid docosahexaenoic

  • Can a Cocktail Prevent Colorectal Adenoma Recurrence?

Can a Cocktail Prevent Colorectal Adenoma Recurrence?

The combination of calcitriol, aspirin, and calcium carbonate did not prevent recurrence of colorectal adenomas over a 3-year period, found a prospective study published in the January issue of Gastroenterology. This negative result might have been affected by the numbers of smokers included in the study or low doses of

  • Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Circulating tumor cells (CTCs) can be isolated from portal venous blood collected during endoscopic ultrasound (EUS) of patients with pancreaticobiliary cancers, researchers report in the December issue of Gastroenterology. CTCs isolated from peripheral blood of patients with metastatic breast, colorectal, or prostate cancer can be analyzed to predict patient survival. However, blood samples from

  • Do Patients Really Prefer Colon Capsule Endoscopy Over Colonoscopy?

Do Patients Really Prefer Colon Capsule Endoscopy Over Colonoscopy?

Slightly more than 50% of people with an inherited risk for colorectal cancer (CRC) agree to undergo screening for this cancer, and most prefer colonoscopy to colon capsule endoscopy—even though these are equally effective screening tools—researchers report in the December issue of Clinical Gastroenterology and Hepatology. Colonoscopy should therefore remain

  • Who Should Undergo Surgery for Pancreatic Cysts?

Who Should Undergo Surgery for Pancreatic Cysts?

When should a patient with a pancreatic cystic lesion undergo surgery? How can we tell if the surgery will provide relief, or prevent death from pancreatic cancer, or burden a patient with an unnecessary procedure? Two articles in the October issue of Clinical Gastroenterology and Hepatology increase our understanding of
