Purpose: Cancer-associated fibroblasts (CAF) are major mediators in tumor microenvironment. We investigated the changes in protein expression in colon cancer-associated fibroblasts compared with normal fibroblasts (NF) in the context of searching for prognostic biomarkers, particularly for stage II patients.
Experimental Design: CAFs and NFs isolated from colon cancer patients were used to identify differentially expressed proteins using quantitative proteomics.
Objective: To determine the clinical, laboratory, serological and histologic characteristics of chronic hepatitis B virus carriers in our environment.
Material And Methods: A retrospective cohort study was performed that included chronic AgHBs carriers aged more than 13 years attending our service since January 2000.
Results: A total of 474 patients were included.
Objectives: To determine the diagnostic value of free perigastric fluid identified by echoendoscopy in patients with gastric cancer and to establish the factors related to the presence of peritoneal carcinomatosis in these patients.
Material And Methods: We retrospectively included 100 patients with a histological diagnosis of gastric adenocarcinoma referred for echoendoscopy. A positive result was defined as the echoendoscopic identification of free perigastric fluid.
Secondary amyloidosis is a rare but serious complication of inflammatory bowel disease that may influence the prognosis even more than the underlying disease. Due to a better knowledge of the association of secondary amyloidosis to inflammatory bowel disease, early diagnosis of this complication is becoming more frequent, but its treatment continues to pose a challenge. We report 4 cases of patients with Crohn´s disease and amyloidosis diagnosed in the inflammatory bowel disease Units of Toledo and Ciudad Real, which represent 0.

Metastatic Crohn's disease is a granulomatous cutaneous lesion that appears in patients with Crohn's disease and is located in any skin area, separated from the lesions in the gastrointestinal tract. This entity is characterized by its heterogeneous behavior, both in its localization and clinical expression and in its effect on patients' quality of life. Histology is essential for diagnosis and shows non-caseating granulomas.

In the present study, we evaluated the utility of a serological panel combining pepsinogen I and II, gastrin-17, and anti-Helicobacter pylori antibodies (Gastropanel) as a screening method for atrophic gastritis.
Patients And Methods: The serological panel was evaluated in 56 patients divided in two groups: group 1 consisted of 47 patients with uninvestigated dyspepsia and group 2 was composed of nine consecutive patients with gastric carcinoma.
Pancreatic metastases represent 2% of pancreatic tumors. The neoplasms most frequently metastasizing to the pancreas are breast, lung, melanoma and kidney tumors. We present the cases of two patients with pancreatic metastases from renal carcinoma diagnosed 4 and 8 years after the diagnosis and surgical treatment of the primary renal tumor.

The purpose of this study was to evaluate, in a prospective, single-center study, the effectiveness of Song's polyurethane stents, modified "in-house," in the percutaneous management of epiphora. Patients (n = 170; age range 18-83, mean = 64; 50 male, 120 female) with severe epiphora had the modified stents inserted (183 eyes/195 stents) to treat unilateral/bilateral and complete/partial obstruction of the nasolacrimal system. The etiology of the obstruction was idiopathic in 119 cases (61%) and chronic dacryocystitis in 76 (39%).

Materials And Methods: Patients (n = 426; age range, 19-88 years, mean, 48; 91 men, 335 women) with severe epiphora had stents (470 eyes/496 stents) inserted to treat unilateral or bilateral and complete or partial obstruction of the nasolacrimal system. The etiology of the obstruction was idiopathic in 280 cases (59.
