The true survival benefit of different curative strategies involving type of operative procedure and timing for patients with initial noncurative colorectal liver metastases remains uncertain. The goal of this study was to examine the effect of primary tumor resection on patients' survival and to clarify the predictive factors related to overall survival (OS).This was a retrospective study that...

Background and Importance: The extent of resection seems a solid prognostic factor in patients suffering from high-grade gliomas (HGGs). When administered orally, 5-ALA is exclusively converted by malignant cells into protoporphyrin IX (PPIX), identifying contrast-enhancing glial lesions under blue 400-nm light. The authors thoroughly assess the efficacy, accuracy, and safety profile of 5-ALA-g...

Primary synovial sarcoma of mediastinum is very rare among soft tissue sarcomas. Only a few cases have been reportedin the literatures. The best treatment is still unclear, but, surgical resection is the main therapy. In this article we reporta case of a 20*20 cm (2000gr) primary giant mediastinal synovial sarcoma in a 42 year-old man. We performed radicalexcision of the tumor...

Chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. It is more common in older age and often affects the axial skeleton. We report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. A 40 yr woman presented with decreasing visual acuity and headache. Magnetic resonance (MR) image revealed a cystic sellar and suprasellar...

  Liposarcoma is a common malignant soft tissue tumor, accounting for 10% to 16% of all sarcomas. Multicentric myxoid liposarcoma is an uncommon condition. Differentiation between several primary tumors and metastasis of a single liposarcoma represents the main difficulty in diagnosis. A 47-years old woman presented with right thigh myxoid liposarcoma and underwent wide margin tumor resection. ...

Surgery represents the mainstream therapeutic modality in oncology. Aggressive radical surgery to achieve no residual tumor would improve survival, which is mainly affected by vascular involvement and accuracy of judging negative margin resection. However, there currently intraoperative tool that can simultaneously perform microscopic analysis peritumoral vasculature vivo surgical pathology ex ...

background & aim: glioblastoma multiforme (gbm), the highest grade glioma (grade iv), is the most malignant form of astrocytoma in adults. this study aimed at evaluating the relationship between demographic, clinical and medical factors with gbm outcome. methods & materials/patients: through a cross-sectional design, 58 patients with newly diagnosed gbm were studied from 1999 to 2015 in guilan ...

BACKGROUND AND PURPOSE Length of survival of patients with low-grade glioma correlates with the extent of tumor resection. These tumors, however, are difficult to distinguish intraoperatively from normal brain tissue, often leading to incomplete resection. Our goal was to evaluate the effectiveness of intraoperative MR guidance in achieving gross-total resection. METHODS We studied 12 patient...
