BACKGROUND Studies have shown the existence of gender- and age-related differences in the incidence and anatomic distribution of colorectal cancers. The purposes of this study were to analyze the distribution characteristics of colorectal cancer patients regarding gender, age, location and tumor size in the course of colonoscopy. MATERIALS AND METHODS All colorectal cancer patients who underw...

BACKGROUND Tumor location of extrahepatic cholangiocarcinoma (CCA) might influence survival after resection. METHODS A consecutive series of 175 patients who had undergone a potentially curative resection of extrahepatic CCA was analyzed. We calculated concordance indices of different constructed prognostic models for survival including TNM (tumour-node-metastasis) staging and developed a nom...

primary cardiac tumors are quite rare, especially in the pediatric age group, and their atypical presentations often prevent a timely diagnosis. most primary cardiac tumors in the pediatric age group are benign. fibromas are generally reported as the second most common primary cardiac tumors in the pediatric age group. these neoplasms are often intramural and involve the left ventricular free w...

Ewing's sarcoma (ES) is a highly malignant neoplasm of childhood and adolescence seen commonly in both axial and appendicular skeleton but uncommonly in acral region. Ewing’s tumor in the hand is extraordinarily rare. Radiological features are variable and can mimic other common lesions. We present a case of 13 year old female, with complaints of pain and swelling in right hand, which on X-ray ...

conclusions pc-rplnd is one the major operations in the field of urology, which is associated with significant adjunctive surgeries. in appropriate cases, pc-rplnd was associated with good cancer specific survival in tertiary oncology center. results twenty-one patients underwent bilateral pc-rplnd. mean age was 26.3 years (ranged 16 - 47). mean size of retroperitoneal mass after chemotherapy w...

Background: Gastrointestinal Stromal Tumor (GIST) arises from the interstitial cells of Cajal. Stomach is most common site GIST. The usual presentations GIST are gastrointestinal bleeding and abdominal pain. GISTs in duodenum uncommon. Duodenal obstruction due to even more usually detected on endoscopy, however they can be missed routine endoscopy if located third part duodenum. Computed Tomogr...

BACKGROUND Assessing the impact of glioma location on prognosis remains elusive. We approached the problem using multivoxel proton magnetic resonance spectroscopic imaging (1H-MRSI) to define a tumor "metabolic epicenter", and examined the relationship of metabolic epicenter location to survival and histopathological grade. METHODS We studied 54 consecutive patients with a supratentorial glio...

Introduction: Glioma is the most common type of primary brain tumor that originates from glial tissues. These types of tumors have a high degree of malignancy and poor prognosis and low survival rates. The evaluation response to treatment is essential to decide whether present treatment is adequate or need for alternative therapy. The aim of this study was to evaluate the resp...

Background: A method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. Materials and Methods: The method was based on the following idea: (i) Before treatment, a series of fluoroscopic images corresponding to different bre...

The safest and most effective cytokine therapies require the favorable accumulation of the cytokine in the tumor environment. While direct treatment into the neoplasm is ideal, systemic tumor-targeted therapies will be more feasible. Electroporation-mediated transfection of cytokine plasmid DNA including a tumor-targeting peptide-encoding sequence is one method for obtaining a tumor-targeted cy...
