Purpose To determine whether gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict presence of lymphovascular invasion and T-stages. Results Gross tumor volume increased with the lymphovascular invasion (r = 0.426, P < 0.0001) and T stage (r = 0.656, P < 0.0001). Univariate analysis showed gross tumor volume could predict lymphovascular inv...

The transcription factor c-Jun mediates several cellular processes, including proliferation and survival, and is upregulated in many carcinomas. Liver-specific inactivation of c-Jun at different stages of tumor development was used to study its role in chemically induced hepatocellular carcinomas (HCCs) in mice. The requirement for c-jun was restricted to early stages of tumor development, and ...

UNLABELLED The aim of this study was the detection of circulating tumor cells (CTC) in three tumor types of epithelial origin. PATIENTS AND METHODS Four hundred and thirty-eight patients with breast cancer (56.2% localized and 43.8% metastatic), 195 with colorectal tumors (84.1% localized and 15.9% metastatic) and 50 with prostate cancer (52% localized and 48% metastatic) took part in this st...

Background: The dynamic phantom is one of the best tools to study the impact of motion on tumor target delineation and absorbed dose verification during dose delivery. Materials and Methods: this study, a 6-DOF (degrees of freedom) phantom was designed following the stacked serial kinematics and assembled by six commercial motion stages to generate 6-DOF motion, which were RotX (pitch, around X...

Differentiation of CD8(+) T cells at the tumor site toward effector and memory stages may represent a key step for the efficacy of antitumor response developing naturally or induced through immunotherapy. To address this issue, CD8(+) T lymphocytes from tumor-invaded (n = 142) and tumor-free (n = 42) lymph nodes removed from the same nodal basin of melanoma patients were analyzed for the expres...

BACKGROUND New tumor markers and markers of tumor progression are needed for improved staging and for better assessment of treatment of many cancers. Gene expression profiling techniques offer the opportunity to discover such markers. We investigated the feasibility of sample pooling strategy in combination with a novel analysis algorithm to identify markers. METHODS Total RNA from human colo...

Transforming growth factor beta (TGFbeta) is a multifunctional polypeptide. Its role in carcinogenesis can be either suppressive or promoting depending on tumor developmental stages and cellular context. During the early phase of epithelial tumorigenesis, TGFbeta inhibits primary tumor development and growth by inducing cell cycle arrest and possibly apoptosis. However, in late stages of progre...
