Generation of tumor-specific cytotoxic T-lymphocytes from the peripheral blood of colorectal cancer patients for adoptive T-cell transfer.

This study designs a strategy for an adoptive cellular therapy (ACT) protocol based on the ex-vivo selection of autologous peripheral blood-derived CD8-enriched T-cells, stimulated with dendritic cells (DCs) that had been pulsed with apoptotic tumor cells to generate cytotoxic T lymphocytes (CTLs) with anti-tumor activity. Seventy-eight colorectal cancer (CRC) patients were enrolled in this study. Tumor tissues and peripheral blood (PB) were obtained at surgery.

Italian multicenter experience of Roux-en-Y gastric bypass on vertical banded gastroplasty: four-year results of effective and safe innovative procedure enabling traditional endoscopic and radiographic study of bypassed stomach and biliary tract.

Background: Cancer, perforation, and bleeding in the bypassed stomach after Roux-en-Y gastric bypass (RYGB) are rare, but serious, complications that need an early diagnosis. Our goal was to perform gastric bypass such that traditional endoscopic and radiographic study of the gastric remnant would be possible and, at the same time, obtain results in terms of weight loss equivalent to those found after standard RYGB. A previously published study demonstrated that complete occlusion of the gastrogastric outlet was not necessary to lose weight.
