Laparoscopic pelvic lymph node dissection system based on preoperative primary tumour stage (T stage) by computed tomography in urothelial bladder cancer: results of a single-institution prospective study.

Unlabelled: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Bladder cancer (BC) is a public health problem throughout the world, and now radical cystectomy (RC) has been introduced as a standard treatment for BC invading muscle and some BCs not invading muscle. Pelvic lymph node dissection (PLND) is considered an integral part of RC for its prognostic and therapeutic significance, but the extent of the PLND has not been precisely defined. Computed tomography is considered one of the most preferable methods to assess the BC stage preoperatively because of its high sensitivity and specificity.

A proteomic study of potential VEGF-C-associated proteins in bladder cancer T24 cells.

Background: Overexpression of vascular endothelial growth factor-C (VEGF-C) has been found to play an important role in malignant progression of various cancer cells, in addition to lymphangiogenesis. However, the mechanisms involved are still largely unknown. Our early research has confirmed that the expression of VEGF-C in bladder cancer was markedly higher than that in normal bladder tissues.

RNA interference-mediated vascular endothelial growth factor-C reduction suppresses malignant progression and enhances mitomycin C sensitivity of bladder cancer T24 cells.

Vascular endothelial growth factor-C (VEGF-C) has been found to be significantly associated with lymphangiogenesis and regional lymph node metastasis in various human tumors. The present work was aimed to explore the role of VEGF-C in malignant progression of human bladder cancer T24 cell line. First, the expression of VEGF-C in T24 cells was detected by western blotting.
