A clinical nomogram incorporating salivary level and oral hygiene index for predicting colorectal cancer.

Background: Emerging evidence demonstrates that the salivary microbiome could serve as a biomarker for various diseases. To date, the oral microbiome's role in the diagnosis of colorectal cancer (CRC) has not been fully elucidated. We aimed to illustrate the salivary microbiome's role in diagnosing and predicting the risk of CRC.

Osteopontin as potential biomarker and therapeutic target in gastric and liver cancers.

Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide, due to late detection and high recurrence rates. Today, these cancers have a heavy socioeconomic burden, for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets. Osteopontin (OPN) is overexpressed in most patients with gastric and liver cancers.

Role of beta1-adrenoceptor in increased lipolysis in cancer cachexia.

Increased production of hormone-sensitive lipase (HSL) protein has been demonstrated to be the major cause behind enhanced lipolysis in cancer cachexia. The mechanism governing this alteration is unknown and was presently investigated. This study was conducted to detect the expression of relevant receptors in the adipocytes of cancer cachexia patients, and to elucidate their implication in the increased lipolysis.

Diagnostic methods for initial evaluation of primary gastrointestinal stromal tumors.

Objective: To describe the imaging features of gastrointestinal stromal tumors (GISTs) at initial presentation with clinical, surgical, and pathologic correlation, and to evaluate values of various techniques in GISTs.

Methods: This retrospective study recruited 70 patients with histologically proved GISTs between December 2004, and May 2009 in the Department of General Surgery, Zhongshan Hospital, Fudan Univeristy, Shanghai, China. Each patient underwent CT scanning, 39 patients underwent simultaneous endoscopy, 12 patients underwent endoscopic ultrasound (EUS), and 36 patients underwent transabdominal ultrasonography (TAUS) simultaneously.

Resting energy expenditure and body composition in patients with newly detected cancer.

Background & Aims: Elevated resting energy expenditure (REE) may be a major determinant in the development of cancer cachexia. The aim of the study was to evaluate REE and body composition in cancer patients and find out the relationship between energy expenditure and substrate utilization.

Methods: Measured resting energy expenditure (mREE), carbohydrate oxidation (C-O), and fat oxidation (F-O) were measured by indirect calorimetry in 714 cancer patients and 642 controls.

[Assessment of energy expenditure and body composition in cancer patients].

Objective: To demonstrate the changes of resting energy expenditure (REE), substrate metabolism and body composition in cancer patients.

Methods: From September 2004 to March 2008, REE, carbohydrate oxidation (CO) and fat oxidation (FO) in 936 cancer patients and 840 control subjects were measured by indirect calorimetry. Bioelectrical impedance appliance was applied to assess intracellular fluid, extracellular fluid, fat mass (FM) and fat free mass (FFM) in the two groups.
